Paper abstract bibtex OBJECTIVE:: To describe and evaluate interventions aimed at reducing psychiatric morbidity in parents and children discharged from PICU. DATA SOURCES:: A systematic review of the literature was undertaken, searching EMBASE, PSYCHinfo, MEDLINE, and CINAHL. Experts in the field were contacted to identify unpublished studies. STUDY SELECTION:: Exclusion criteria: Studies with participants above age 18 or drawn from a neonatal ICU, studies not in English, and those not measuring psychopathology. DATA EXTRACTION:: Seven hundred fifty-three articles initially identified were hand searched which identified three studies, with a further three studies found by contacting experts in the field. Of these, three were randomized controlled trials and three feasibility studies. DATA SYNTHESIS:: The interventions primarily targeted parents (particularly mothers), with the aim of reducing psychopathology especially posttraumatic stress disorder. Findings from these few studies demonstrated that interventions can lead to a reduction in parent and child psychopathology. Key ingredients of these interventions included psychoeducation, parent support after discharge, offering intervention to those families at high risk of developing psychopathology as identified by screening at the point of discharge, follow-up of all families with the aim of case finding, and specific interventions to target posttraumatic stress disorder symptoms. CONCLUSIONS:: Intervention studies are few but do lead to reductions in parent and child psychopathology. There is sufficient information to suggest some of these interventions could be supported and further evaluated.

}Midwife-led maternity care in Ireland - a retrospective cohort study. Dencker A., Smith V., McCann C., & Begley C. 2017.
Paper abstract bibtex
Paper abstract bibtex Background: Midwife-led maternity care is shown to be safe for women with low-risk during pregnancy. In Ireland, two midwife-led units (MLUs) were introduced in 2004 when a randomised controlled trial (the MidU study) was performed to compare MLU care with consultant-led care (CLU). Following study completion the two MLUs have remained as a maternity care option in Ireland. The aim of this study was to evaluate maternal and neonatal outcomes and transfer rates during six years in the larger of the MLU sites. Methods: MLU data for the six years 2008-2013 were retrospectively analysed, following ethical approval. Rates of transfer, reasons for transfer, mode of birth, and maternal and fetal outcomes were assessed. Linear-by-Linear Association trend analysis was used for categorical data to evaluate trends over the years and one-way ANOVA was used when comparing continuous variables. Results: During the study period, 3,884 women were registered at the MLU. The antenatal transfer rate was 37.4% and 2,410 women came to labour in the MLU. Throughout labour and birth, 567 women (14.6%) transferred to the CLU, of which 23 were transferred after birth due to need for suturing or postpartum hemorrhage. The most common reasons for intrapartum transfer were meconium stained liquor/abnormal fetal heart rate (30.3%), delayed labour progress in first or second stage (24.9%) and woman's wish for epidural analgesia (15.1%). Of the 1,903 babies born in the MLU, 1,878 (98.7%) were spontaneous vaginal births and 25 (1.3%) were instrumental (ventouse/forceps). Only 25 babies (1.3%) were admitted to neonatal intensive care unit. All spontaneous vaginal births from the MLU registered population, occurring in the study period in both the MLU and CLU settings (n = 2,785), were compared. In the MLU more often 1-2 midwives (90.9% vs 69.7%) cared for the women during birth, more women had three vaginal examinations or fewer (93.6% vs 79.9%) and gave birth in an upright position (standing, squatting or kneeling) (52.0% vs 9.4%), fewer women had an amniotomy (5.9% vs 25.9%) or episiotomy (3.4% vs 9.7%) and more women had a physiological management of third stage of labour (50.9% vs 4.6%). Conclusions: Midwife-led care is a safe option that could be offered to a large proportion of healthy pregnant women. With strict transfer criteria there are very few complications during labour and birth. Maternity units without the option of MLU care should consider its introduction.

Caregiver-directed home-based intensive bimanual training in young children with unilateral spastic cerebral palsy: A randomized trial. Ferre C.L., Brandao M., Surana B., Dew A.P., Moreau N.G., & Gordon A.M. 2016.
Paper abstract bibtex
Paper abstract bibtex Aim: To examine the efficacy of caregiver-directed, home-based intensive bimanual training in children with unilateral spastic cerebral palsy (USCP) using a randomized control trial. Method: Twenty-four children (ages 2y 6mo-10y 1mo; 10 males, 14 females) performed home-based activities directed by a caregiver for 2 hours per day, 5 days per week, for 9 weeks (total=90h). Cohorts of children were age-matched into groups and randomized to receive home-based hand-arm bimanual intensive therapy (H-HABIT; n=12) or lower-limb functional intensive training (LIFT-control; n=12). Caregivers were trained before the intervention and supervised remotely via telerehabilitation. Dexterity and bimanual hand function were assessed using the Box and Blocks test (BBT) and the Assisting Hand Assessment (AHA) respectively. Caregiver perception of functional goals was measured using the Canadian Occupational Performance Measure (COPM). Results: H-HABIT showed greater improvement on the BBT compared to LIFT-control and no improvement on the AHA. H-HABIT demonstrated significant improvement in COPM-Performance compared to LIFT-control and both groups showed equal improvement in COPM-Satisfaction. Interpretation: H-HABIT improved dexterity and performance of functional goals, but not bimanual performance, in children with USCP compared to a control group receiving intervention of equal intensity/duration that also controlled for increased caregiver attention. Home-based models provide a valuable, family-centered approach to achieve increased treatment intensity. Copyright © 2016 Mac Keith Press.

The aim of the study was to investigate the epidemiology and clinical features of bloodstream infections due to Escherichia coli producing AmpC β-lactamases (AmpC-Ec-BSI). In a multi-centre case-control study, all third-generation-cephalosporin-resistant Escherichia coli BSI (3GC-Ec-BSI) isolates were analysed. Acquired bla AmpC (bla ac-AmpC) detection was done by polymerase chain reaction (PCR) and sequencing. Chromosomal bla AmpC (bla c-AmpC) expression was quantified by real-time PCR. Cases were patients with AmpC-Ec-BSI. Controls were patients with cephalosporin-susceptible E. coli BSI, matched 1:1 by sex and age. Demographics, comorbidities, intrinsic and extrinsic risk factors for antimicrobial resistance, clinical presentation and outcomes were investigated. Among 841 E. coli BSI, 17 were caused by AmpC-Ec (2 %). Eleven isolates (58.8 %) had bla ac-AmpC and six were bla c-AmpC overproducers. The mean age of cases was 66.2 years and 71 % were men. Cases were more frequently healthcare-related (82 vs. 52 % controls, p \textless 0.05) and presented more intrinsic and extrinsic risk factors. At least one risk factor was present in 94.1 % of cases vs. 41.7 % of controls (p = 0.002). Severity and length of stay (LOS) were higher among cases (mean Pitt Score 2.6 vs. 0.38 in controls, p = 0.03; LOS 17.5 days vs. 6 in controls, p = 0.02). Inappropriate empirical therapy (IET) was administered to 70.6 % of cases and 23.5 % of controls (p \textless 0.003). No differences were found in terms of cure rate at the 14th day and mortality. Bloodstream infections due to AmpC-Ec (mostly plasmid-mediated) are infrequent in our area. AmpC-Ec-BSI affects mainly patients with intrinsic risk factors and those with previous antibiotic exposure. A high proportion received IET.

}Pharmacokinetics and pharmacodynamics of albuterol multidose dry powder inhaler and albuterol hydrofluoroalkane in children with asthma. Ratnayake A., Taveras H., Iverson H., & Shore P. 2016.
Paper abstract bibtex
Paper abstract bibtex Background: Many children struggle with the use of albuterol hydrofluoroalkane (HFA) inhalers. Albuterol multidose dry powder inhaler (MDPI) may simplify rescue bronchodilator use in children. Objective: To compare the pharmacokinetics (PK), pharmacodynamics (PD), and tolerability of albuterol MDPI and albuterol HFA after a single inhaled dose in children with asthma. Methods: This single-center, open-label, two-period crossover study randomized children to albuterol MDPI or HFA 180 mug on two treatment days with a 4- to 14-day washout. Plasma albuterol concentrations were measured before the dose and up to 10 hours after the dose to determine the primary PK values of area under the plasma concentration-versus-time curve from time 0 to the last measurable concentration (AUC0-t), maximum observed concentration (Cmax), and AUC from time 0 extrapolated to infinity (AUC0-inf). Heart rate and blood pressure before the dose and after the dose were monitored for PD effects, and adverse events (AE) were monitored for overall safety. Results: Fifteen children, ages 6-11 years, were included (PK, n = 13 for time to Cmax and terminal half-life of elimination; n = 12 for AUC and Cmax due to incomplete data). AUC0-t (geometric mean ratio [GMR] 1.056 [90% confidence interval \CI\, 0.88 -1.268]) and AUC0-inf (GMR 0.971 [90% CI, 0.821-1.147]) were comparable between treatments. Cmax was larger for albuterol MDPI versus HFA (GMR 1.340 [90% CI, 1.098 -1.636]). PD parameters between the treatments were comparable. No deaths, serious AEs, treatment-emergent AEs, or withdrawals due to AEs were reported for either treatment. Conclusion: Albuterol MDPI and albuterol HFA had comparable PK and PD in children after a single 180-mug dose. Copyright ©2016, OceanSide Publications, Inc., U.S.A.

Acceptance and Commitment Therapy (ACT) has been effectively utilized to treat both chronic pain and substance use disorder independently. Given these results and the vital need to treat the comorbidity of the two disorders, a pilot ACT treatment was implemented in individuals with comorbid chronic pain and opioid addiction. This pilot study supported using neurophysiology to characterize treatment effects and revealed that, following ACT, participants with this comorbidity exhibited reductions in brain activation due to painful stimulus and in connectivity at rest.

}Absolute and relative educational inequalities in obesity among adults in Tehran: Findings from the Urban HEART Study-2. Kiadaliri, A. A., Asadi-Lari, M., Kalantari, N., Jafari, M., Vaez Mahdavi, M. R., & Faghihzadeh, S. Obesity Research & Clinical Practice, 10 Suppl 1:S57–S63, September, 2016.

BACKGROUND: The prevalence of obesity is increasing in Iran. Previous studies showed mixed results in relation to association between socioeconomic status and obesity in the country. The current study aimed to examine educational inequalities among adults in Tehran in 2011. METHOD: Data on 90,435 persons 18 years and older from Urban Health Equity Assessment and Response Tool (Urban HEART-2) were analyzed. The Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) were used for assessing educational inequalities in obesity. These measures were quantified using generalized linear models for the binomial family adjusted for sex and age. Subgroup analysis was conducted across sex, age groups and the 22 districts of Tehran. RESULTS: Both SII and RII showed substantial educational inequalities in obesity in favour of more educated adults [RII and SII (95% CI were equal to 2.91 (2.71-3.11) and 0.12 (0.12-0.13)), respectively]. These educational inequalities were persistent even after adjusting for employment, marital status and smoking. Subgroup analysis revealed that educational inequalities were more profound among women. While among men educational inequalities were generally increasing with age, an inverse trend was observed among women. Educational inequalities were observed within all 22 districts of Tehran and generally there were no statistically significant differences between districts. CONCLUSION: An inverse association between education and obesity was observed in the current study. To decrease educational inequalities in Tehran, priority should be given to younger women and older men. Further analyses are needed to explain these inequalities.

abstract = {BACKGROUND: The prevalence of obesity is increasing in Iran. Previous studies showed mixed results in relation to association between socioeconomic status and obesity in the country. The current study aimed to examine educational inequalities among adults in Tehran in 2011.
METHOD: Data on 90,435 persons 18 years and older from Urban Health Equity Assessment and Response Tool (Urban HEART-2) were analyzed. The Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) were used for assessing educational inequalities in obesity. These measures were quantified using generalized linear models for the binomial family adjusted for sex and age. Subgroup analysis was conducted across sex, age groups and the 22 districts of Tehran.
RESULTS: Both SII and RII showed substantial educational inequalities in obesity in favour of more educated adults [RII and SII (95\% CI were equal to 2.91 (2.71-3.11) and 0.12 (0.12-0.13)), respectively]. These educational inequalities were persistent even after adjusting for employment, marital status and smoking. Subgroup analysis revealed that educational inequalities were more profound among women. While among men educational inequalities were generally increasing with age, an inverse trend was observed among women. Educational inequalities were observed within all 22 districts of Tehran and generally there were no statistically significant differences between districts.
CONCLUSION: An inverse association between education and obesity was observed in the current study. To decrease educational inequalities in Tehran, priority should be given to younger women and older men. Further analyses are needed to explain these inequalities.},

Both genetics and physical activity (PA) contribute to bone mineral density (BMD), but it is unknown if the benefits of physical activity on childhood bone accretion depend on genetic risk. We, therefore, aimed to determine if PA influenced the effect of bone fragility genetic variants on BMD in childhood. Our sample comprised US children of European ancestry enrolled in the Bone Mineral Density in Childhood Study (N = 918, aged 5 to 19 years, and 52.4% female). We used a questionnaire to estimate hours per day spent in total, high-, and low-impact PA. We calculated a BMD genetic score (% BMD lowering alleles) using adult genome-wide association study (GWAS)-implicated BMD variants. We used dual-energy X-ray absorptiometry to estimate femoral neck, total hip, and spine areal-BMD and total body less head (TBLH) bone mineral content (BMC) Z-scores. The BMD genetic score was negatively associated with each bone Z-score (eg, TBLH-BMC: estimate = -0.03, p = 1.3 × 10(-6) ). Total PA was positively associated with bone Z-scores; these associations were driven by time spent in high-impact PA (eg, TBLH-BMC: estimate = 0.05, p = 4.0 × 10(-10) ) and were observed even for children with lower than average bone Z-scores. We found no evidence of PA-adult genetic score interactions (p interaction \textgreater 0.05) at any skeletal site, and there was no evidence of PA-genetic score-Tanner stage interactions at any skeletal site (p interaction \textgreater 0.05). However, exploratory analyses at the individual variant level revealed that PA statistically interacted with rs2887571 (ERC1/WNT5B) to influence TBLH-BMC in males (p interaction = 7.1 × 10(-5) ), where PA was associated with higher TBLH-BMC Z-score among the BMD-lowering allele carriers (rs2887571 AA homozygotes: estimate = 0.08 [95% CI 0.06, 0.11], p = 2.7 × 10(-9) ). In conclusion, the beneficial effect of PA on bone, especially high-impact PA, applies to the average child and those genetically predisposed to lower adult BMD (based on GWAS-implicated BMD variants). Independent replication of our exploratory individual variant findings is warranted. © 2016 American Society for Bone and Mineral Research.

AIM: To analyze how the characteristics of institutionalized older people with dementia and residential care centers are associated with the individual's quality of life (QoL). METHODS: Data were collected from a survey carried out on 525 elderly people aged 60 years or older in 14 nursing care homes across Spain. Multilevel linear analysis to assess the differences in QoL level between centers and individuals was carried out. RESULTS: The characteristics of the individuals that were associated with a higher QoL were functional independence, health status and gathering with family, friends or neighbors. In contrast, higher levels of dementia, depression and the length of institutionalization had a negative effect on QoL. In relation to the residential care center characteristics, the availability of geriatricians was associated with higher QoL, compared with those centers with no geriatricians on staff. In addition, public centers (public ownership and publicly-funded residents) were also associated with higher QoL than private/mixed centers. The multilevel analysis showed that the 16.4% of the differences in QoL was related to residence factors. CONCLUSION: These results reflect the importance of the functional, social, mental and residential dimensions in the QoL of older adults with dementia. Actions devoted to improving these key dimensions would contribute to promote the well-being of this vulnerable population.

doi abstract bibtex
OBJECTIVES: To validate the performance of a set of risk prediction algorithms developed using the QResearch database, in an independent sample from general practices contributing to the Clinical Research Data Link (CPRD). SETTING: Prospective open cohort study using practices contributing to the CPRD database and practices contributing to the QResearch database. PARTICIPANTS: The CPRD validation cohort consisted of 3.3 million patients, aged 25-99 years registered at 357 general practices between 1 Jan 1998 and 31 July 2012. The validation statistics for QResearch were obtained from the original published papers which used a one-third sample of practices separate to those used to derive the score. A cohort from QResearch was used to compare incidence rates and baseline characteristics and consisted of 6.8 million patients from 753 practices registered between 1 Jan 1998 and until 31 July 2013. OUTCOME MEASURES: Incident events relating to seven different risk prediction scores: QRISK2 (cardiovascular disease); QStroke (ischaemic stroke); QDiabetes (type 2 diabetes); QFracture (osteoporotic fracture and hip fracture); QKidney (moderate and severe kidney failure); QThrombosis (venous thromboembolism); QBleed (intracranial bleed and upper gastrointestinal haemorrhage). Measures of discrimination and calibration were calculated. RESULTS: Overall, the baseline characteristics of the CPRD and QResearch cohorts were similar though QResearch had higher recording levels for ethnicity and family history. The validation statistics for each of the risk prediction scores were very similar in the CPRD cohort compared with the published results from QResearch validation cohorts. For example, in women, the QDiabetes algorithm explained 50% of the variation within CPRD compared with 51% on QResearch and the receiver operator curve value was 0.85 on both databases. The scores were well calibrated in CPRD. CONCLUSIONS: Each of the algorithms performed practically as well in the external independent CPRD validation cohorts as they had in the original published QResearch validation cohorts.

BACKGROUND: Undernutrition, weight loss and dehydration are major clinical issues for people with dementia in residential care, with excessive weight loss contributing to increased risk of frailty, immobility, illness and premature morbidity. This paper discusses a nutritional knowledge and attitudes survey conducted as part of a larger project focused on improving nutritional intake of people with dementia within a residential care facility in Brisbane, Australia. AIMS: The specific aims of the survey were to identify (i) knowledge of the nutritional needs of aged care facility residents; (ii) mealtime practices; and (iii) attitudes towards mealtime practices and organisation. METHODS: A survey based on those used in other healthcare settings was completed by 76 staff members. The survey included questions about nutritional knowledge, opinions of the food service, frequency of feeding assistance provided and feeding assessment practices. RESULTS: Nutritional knowledge scores ranged from 1 to 9 of a possible 10, with a mean score of 4.67. While 76% of respondents correctly identified risk factors associated with malnutrition in nursing home residents, only 38% of participants correctly identified the need for increased protein and energy in residents with pressure ulcers, and just 15% exhibited correct knowledge of fluid requirements. Further, while nutritional assessment was considered an important part of practice by 83% of respondents, just 53% indicated that they actually carried out such assessments. Identified barriers to promoting optimal nutrition included insufficient time to observe residents (56%); being unaware of residents' feeding issues (46%); poor knowledge of nutritional assessments (44%); and unappetising appearance of food served (57%). CONCLUSION: An important step towards improving health and quality of life for residents of aged care facilities would be to enhance staff nutritional awareness and assessment skills. This should be carried out through increased attention to both preservice curricula and on-the-job training. IMPLICATIONS FOR PRACTICE: The residential facility staff surveyed demonstrated low levels of nutrition knowledge, which reflects findings from the international literature. This has implications for the provision of responsive care to residents of these facilities and should be explored further.

PURPOSE OF REVIEW: In the last decade, sporadic and lethal human disease caused by zoonotic avian influenza viruses, and the seasonal activity of human H1N1 2009 pandemic type have driven intense epidemiological and laboratory studies into the virus life cycle. This article highlights major developments from mid-2012 to early 2014. RECENT FINDINGS: Advances in molecular techniques and efficient rollout of diagnostic tests have enabled the rapid identification of clinical cases and detailed genetic sequencing of viral genomes. Studies have contributed widely to the understanding of how and when influenza viruses circulate, what determines their innate pathogenicity in particular hosts and whether host cofactors influence disease severity. Other imperatives include investigations into how influenza can be better prevented by vaccination, or treated with antiviral drugs. SUMMARY: Avian influenza viruses present a continuous threat to human populations. There is a need for sustained surveillance and downstream research to evaluate the potential for future pandemics.

Open burnings (forest fires, agricultural, and garbage burnings) are the major sources of air pollution in Chiang Mai, Thailand. A time series prospective study was conducted in which 3025 participants were interviewed for 19 acute symptoms with the daily records of ambient air pollutants: particulate matter less than 10 microm in size (PM10), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3). PM10 was positively associated with blurred vision with an adjusted odds ratio (OR) of 1.009. CO was positively associated with lower lung and heart symptoms with adjusted ORs of 1.137 and 1.117. NO2 was positively associated with nosebleed, larynx symptoms, dry cough, lower lung symptoms, heart symptoms, and eye irritation with the range of adjusted ORs (ROAORs) of 1.024 to 1.229. SO2 was positively associated with swelling feet, skin symptoms, eye irritation, red eyes, and blurred vision with ROAORs of 1.205 to 2.948. Conversely, O3 was negatively related to running nose, burning nose, dry cough, body rash, red eyes, and blurred vision with ROAORs of 0.891 to 0.979.

A time series prospective study was conducted in which 3025 participants were interviewed for 19 acute symptoms with the daily records of ambient air pollutants: particulate matter less than 10 microm in size (PM10), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3). PM10 was positively associated with blurred vision with an adjusted odds ratio (OR) of 1.009. CO was positively associated with lower lung and heart symptoms with adjusted ORs of 1.137 and 1.117. NO2 was positively associated with nosebleed, larynx symptoms, dry cough, lower lung symptoms, heart symptoms, and eye irritation with the range of adjusted ORs (ROAORs) of 1.024 to 1.229. SO2 was positively associated with swelling feet, skin symptoms, eye irritation, red eyes, and blurred vision with ROAORs of 1.205 to 2.948. Conversely, O3 was negatively related to running nose, burning nose, dry cough, body rash, red eyes, and blurred vision with ROAORs of 0.891 to 0.979.},

Paper doi abstract bibtex OBJECTIVE: The aim of our study is to show that surgery followed by Gamma Knife Radiosurgery is an effective and safe combined treatment for the control of intracranial meningiomas located close to critical structures. MATERIALS AND METHODS: This retrospective study followed 31 patients with intracranial meningioma between 2005 and 2010. We included patients when initial therapeutic decision was deliberate subtotal surgical resection preparing a target for early postoperative GKR. Early MRI was performed to evaluate the tumor residual volume after surgical procedure. Annual MRI was performed to detect any tumor progression. RESULTS: The mean follow-up was 4.5 years. The mean margin dose was 14.5 Gy and the mean target volume was 2.4 cm3. The mean progression free survival after combined treatment was 4.4 years in the irradiated target volume and 3.9 years on the limit or remotely of irradiated target volume. Of all patients, we recorded 5 tumor progressions after combined treatment, in-field in 1 case and out-of-field in 4 cases. All tumor progressions were high-grade meningiomas. CONCLUSION: Surgery followed by radiosurgery is a safe and effective combined treatment for intracranial meningiomas. We recommend it in case of meningioma located close to critical structures for which it is safer to leave in place a tumor remnant to reduce morbidity.

BACKGROUND: Auditory verbal hallucinations (AVH) in schizophrenia may arise because of aberrant speech perception. We used an electroencephalography method to examine the neural processes underlying speech perception in schizophrenic patients with hallucinations. METHODS: Cortical event-related potentials (ERPs) were analyzed topographically (scalp potential and scalp current density (SCD) mapping) in response to the vowel /a/ using a passive paradigm in 26 patients with schizophrenia. RESULTS: From the SCD distribution of the P1 peak, we showed that, whereas the hallucination score (PSYRATS) was negatively correlated with the amplitude of the frontal currents, the PANSS negative symptom score was negatively correlated with the amplitude of the temporal currents in patients with schizophrenia. CONCLUSIONS: These results provide evidence that AVH and negative symptoms are associated with abnormal early processing of speech. Whereas AVH are related to decreased early frontal activation, negative symptoms are associated with a reduced early temporal response.

OBJECTIVE: Middle-aged people with diabetes have been reported to have significantly higher risks of cardiovascular events than people without diabetes. However, recent falls in cardiovascular disease rates and more active management of risk factors may have abolished the increased risk. We aimed to provide an up-to-date assessment of the relative risks associated with type 2 diabetes of all-cause and cardiovascular mortality in middle-aged people in the U.K. RESEARCH DESIGN AND METHODS: Using data from the General Practice Research Database, from 2004 to 2010, we conducted a cohort study of 87,098 people, 40-65 years of age at baseline, comparing 21,798 with type 2 diabetes and 65,300 without diabetes, matched on age, sex, and general practice. We produced hazard ratios (HRs) for mortality and compared rates of blood pressure testing, cholesterol monitoring, and use of aspirin, statins, and antihypertensive drugs. RESULTS People with type 2 diabetes, compared with people without diabetes, had a twofold increased risk of all-cause mortality (HR 2.07 [95% CI 1.95-2.20], adjusted for smoking) and a threefold increased risk of cardiovascular mortality (3.25 [2.87-3.68], adjusted for smoking). Women had a higher relative risk than men, and people \textless55 years of age had a higher relative risk than those \textgreater55 years of age. Monitoring and medication rates were higher in those with diabetes (all P \textless 0.001). CONCLUSIONS: Despite efforts to manage risk factors, administer effective treatments, and develop new therapies, middle-aged people with type 2 diabetes remain at significantly increased risk of death.

Non-typhoidal Salmonella are an important but poorly characterized cause of paediatric diarrhoea in developing countries. We conducted a hospital-based case-control study in children aged \textless5 years in Ho Chi Minh City to define the epidemiology and examine risk factors associated with Salmonella diarrhoeal infections. From 1419 diarrhoea cases and 571 controls enrolled between 2009 and 2010, 77 (54%) diarrhoea cases were stool culture-positive for non-typhoidal Salmonella. Salmonella patients were more likely to be younger than controls (median age 10 and 12 months, respectively) [odds ratio (OR) 097; 95% confidence interval (CI) 094-099], to report a recent diarrhoeal contact (81% cases, 18% controls; OR 598, 95% CI 18-204) and to live in a household with \textgreater2 children (cases 208%, controls 102%; OR 232, 95% CI 12-47). Our findings indicate that Salmonella are an important cause of paediatric gastroenteritis in this setting and we suggest that transmission may occur through direct human contact in the home.

IMPORTANCE: Handoff miscommunications are a leading cause of medical errors. Studies comprehensively assessing handoff improvement programs are lacking. OBJECTIVE: To determine whether introduction of a multifaceted handoff program was associated with reduced rates of medical errors and preventable adverse events, fewer omissions of key data in written handoffs, improved verbal handoffs, and changes in resident-physician workflow. DESIGN, SETTING, AND PARTICIPANTS: Prospective intervention study of 1255 patient admissions (642 before and 613 after the intervention) involving 84 resident physicians (42 before and 42 after the intervention) from July-September 2009 and November 2009-January 2010 on 2 inpatient units at Boston Children's Hospital. INTERVENTIONS: Resident handoff bundle, consisting of standardized communication and handoff training, a verbal mnemonic, and a new team handoff structure. On one unit, a computerized handoff tool linked to the electronic medical record was introduced. MAIN OUTCOMES AND MEASURES: The primary outcomes were the rates of medical errors and preventable adverse events measured by daily systematic surveillance. The secondary outcomes were omissions in the printed handoff document and resident time-motion activity. RESULTS: Medical errors decreased from 33.8 per 100 admissions (95% CI, 27.3-40.3) to 18.3 per 100 admissions (95% CI, 14.7-21.9; P < .001), and preventable adverse events decreased from 3.3 per 100 admissions (95% CI, 1.7-4.8) to 1.5 (95% CI, 0.51-2.4) per 100 admissions (P = .04) following the intervention. There were fewer omissions of key handoff elements on printed handoff documents, especially on the unit that received the computerized handoff tool (significant reductions of omissions in 11 of 14 categories with computerized tool; significant reductions in 2 of 14 categories without computerized tool). Physicians spent a greater percentage of time in a 24-hour period at the patient bedside after the intervention (8.3%; 95% CI 7.1%-9.8%) vs 10.6% (95% CI, 9.2%-12.2%; P = .03). The average duration of verbal handoffs per patient did not change. Verbal handoffs were more likely to occur in a quiet location (33.3%; 95% CI, 14.5%-52.2% vs 67.9%; 95% CI, 50.6%-85.2%; P = .03) and private location (50.0%; 95% CI, 30%-70% vs 85.7%; 95% CI, 72.8%-98.7%; P = .007) after the intervention. CONCLUSIONS AND RELEVANCE: Implementation of a handoff bundle was associated with a significant reduction in medical errors and preventable adverse events among hospitalized children. Improvements in verbal and written handoff processes occurred, and resident workflow did not change adversely.

Website abstract bibtex OBJECTIVES: To determine if a prediction rule for hospital mortality using dynamic variables in response to treatment of hypotension in patients with sepsis performs better than current models.\n\nDESIGN: Retrospective cohort study.\n\nSETTING: All ICUs at a tertiary care hospital.\n\nPATIENTS: Adult patients admitted to ICUs between 2001 and 2007 of whom 2,113 met inclusion criteria and had sufficient data.\n\nINTERVENTIONS: None.\n\nMEASUREMENTS AND MAIN RESULTS: We developed a prediction algorithm for hospital mortality in patients with sepsis and hypotension requiring medical intervention using data from the Multiparameter Intelligent Monitoring in Intensive Care II. We extracted 189 candidate variables, including treatments, physiologic variables and laboratory values collected before, during, and after a hypotensive episode. Thirty predictors were identified using a genetic algorithm on a training set (n=1500) and validated with a logistic regression model on an independent validation set (n=613). The final prediction algorithm used included dynamic information and had good discrimination (area under the receiver operating curve=82.0%) and calibration (Hosmer-Lemeshow C statistic=10.43, p=0.06). This model was compared with Acute Physiology and Chronic Health Evaluation IV using reclassification indices and was found to be superior with an Net Reclassification Improvement of 0.19 (p<0.001) and an Integrated Discrimination Improvement of 0.09 (p<0.001).\n\nCONCLUSIONS: Hospital mortality predictions based on dynamic variables surrounding a hypotensive event is a new approach to predicting prognosis. A model using these variables has good discrimination and calibration and offers additional predictive prognostic information beyond established ones.

The final prediction algorithm used included dynamic information and had good discrimination (area under the receiver operating curve=82.0%) and calibration (Hosmer-Lemeshow C statistic=10.43, p=0.06). This model was compared with Acute Physiology and Chronic Health Evaluation IV using reclassification indices and was found to be superior with an Net Reclassification Improvement of 0.19 (p<0.001) and an Integrated Discrimination Improvement of 0.09 (p<0.001).\n\nCONCLUSIONS: Hospital mortality predictions based on dynamic variables surrounding a hypotensive event is a new approach to predicting prognosis. A model using these variables has good discrimination and calibration and offers additional predictive prognostic information beyond established ones.},

Paper abstract bibtex
Paper abstract bibtex Long term quality of life data of adult patients harboring intracranial ependymomas have not been reported. The role of adjuvant radiation therapy in Grade II ependymomas is unclear and differs from study to study. We therefore sought to retrospectively analyze outcome and quality of life of adult patients that were operated on intracranial ependymomas at four different surgical centers in two countries. All patients were attempted to be contacted via telephone to assess quality of life (QoL) at the time of the telephone interview. The standard EORTC QoL Questionnaire C30 (EORTC QLQ-C30) and the EORTC QLQ-Brain Cancer Module (QLQ-BN20) were used. 64 adult patients with intracranial ependymomas were included in the study. The only factor that was associated with increased survival was age <55 years (p < 0.001). Supratentorial location was correlated with shorter progression free survival than infratentorial location (PFS; p = 0.048). In WHO Grade II tumors local irradiation did not lead to increased PFS (p = 0.888) or overall survival (p = 0.801). Even for incompletely resected Grade II tumors local irradiation did not lead to a benefit in PFS (p = 0.911). In a multivariate analysis of QoL, irradiated patients had significantly worse scores in the item "fatigue" (p = 0.037) than non-irradiated patients. Here we present QoL data of adult patients with intracranial ependymomas. Our data show that local radiation therapy may have long-term effects on patients' QoL. Since in the incompletely resected Grade II tumors local irradiation did not lead to a benefit in PFS in this retrospective study, prospective randomized studies are necessary. In addition to age, supratentorial tumor location is associated with a worse prognosis in adult ependymoma patients.

Website abstract bibtex We investigated the effectiveness of dedicated orthopedic operating rooms (OR) on minimizing time spent on perioperative processes to increase OR throughput in total knee and hip arthroplasty procedures. The use of a dedicated orthopedic unit that included 6 ORs with staff allocated only for those ORs was compared to the use of a traditional staffing model. After matching to simulate randomization, each group consisted of 422 procedures. The dedicated orthopedic unit improved average anesthesia controlled time by 4 minutes (P<.001), operative time by 7 minutes (P=.004) and turnover time by 8 minutes (P<.001). An overall improvement of 19 minutes per procedure using the dedicated unit was observed.

Acute central nervous system (CNS) infections cause substantial morbidity and mortality, but the etiology remains unknown in a large proportion of cases. We identified and characterized the full genome of a novel cyclovirus (tentatively named cyclovirus-Vietnam [CyCV-VN]) in cerebrospinal fluid (CSF) specimens of two Vietnamese patients with CNS infections of unknown etiology. CyCV-VN was subsequently detected in 4% of 642 CSF specimens from Vietnamese patients with suspected CNS infections and none of 122 CSFs from patients with noninfectious neurological disorders. Detection rates were similar in patients with CNS infections of unknown etiology and those in whom other pathogens were detected. A similar detection rate in feces from healthy children suggested food-borne or orofecal transmission routes, while high detection rates in feces from pigs and poultry (average, 58%) suggested the existence of animal reservoirs for such transmission. Further research is needed to address the epidemiology and pathogenicity of this novel, potentially zoonotic virus.

BACKGROUND: An updated probabilistic causality assessment method and the Liverpool algorithm presented as an improved version of the Naranjo algorithm, one of the most used and accepted causality assessment methods, have recently been proposed. OBJECTIVE: In order to test the validity of the probabilistic method in routine pharmacovigilance, results provided by the Naranjo and Liverpool algorithms, as well as the updated probabilistic method, were each compared with a consensual expert judgement taken as reference. METHODS: A sample of 59 drug-event pairs randomly sampled from spontaneous reports to the French pharmacovigilance system was assessed by expert judgement until reaching consensus and by members of a pharmacovigilance unit using the updated probabilistic method, the Naranjo and Liverpool algorithms. Probabilities given by the probabilistic method, and categories obtained by both the Naranjo and the Liverpool algorithms were compared as well as their sensitivity, specificity, positive and negative predictive values. RESULTS: The median probability for drug causation given by the consensual expert judgement was 0.70 (inter-quartile range, IQR 0.54-0.84) versus 0.77 (IQR 0.54-0.91) for the probabilistic method. For the Naranjo algorithm, the 'possible' causality category was predominant (61 %), followed by 'probable' (35 %), 'doubtful', and 'almost certain' categories (2 % each). Category distribution obtained with the Liverpool algorithm was similar to that obtained by the Naranjo algorithm with a majority of 'possible' (61 %) and 'probable' (30 %) followed by 'definite' (7 %) and 'unlikely' (2 %). For the probabilistic method, sensitivity, specificity, positive and negative predictive values were 0.96, 0.56, 0.92 and 0.71, respectively. For the Naranjo algorithm, depending on whether the 'possible' category was considered in favour or in disfavour of drug causation, sensitivity was, respectively, 1 or 0.42, specificity 0.11 or 0.89, negative predictive value 1 or 0.22 and positive predictive value 0.86 or 0.95; results were identical for the Liverpool algorithm. CONCLUSION: The logistic probabilistic method gave results closer to the consensual expert judgment than either the Naranjo or Liverpool algorithms whose performance were strongly dependent on the meaning given to the 'possible' category. Owing to its good sensitivity and positive predictive value and by providing results as continuous probabilities, the probabilistic method seems worthy to use for a trustable assessment of adverse drug reactions in routine practice.

Paper doi abstract bibtex
Paper doi abstract bibtex Abstract Abstract: In Italy, Emergency Hormonal Contraception (EHC) is a prescription drug, available only in pharmacies. Evidence suggests that a number of doctors and pharmacists refuse to provide EHC, on grounds of conscience, although the exact frequency of this phenomenon is unknown. This creates a barrier to access to EHC for women, thus risking undermining their right to reproductive self-determination. In this article, we aim to offer a clearer empirical and theoretical understanding of the situation and to assess the force of doctors’ and pharmacists’ claims against providing EHC. Unlike standard discussions of the issue, we argue that the category of conscientious objection is not the most appropriate one for making sense of these claims, because they are not grounded in a conflict between two contrasting moral duties. The seemingly forced choice between protecting doctors’ and pharmacists’ professional self-determination and women’s reproductive self-determination could be prevented by distributing EHC without medical prescription and in a number of outlets (including supermarkets), thus relieving doctors and pharmacists from the legal duty to provide it.

AIMS: To estimate the prevalence of dyslipidaemias in high-risk patients new to lipid-modifying therapy (LMT), and establish the extent to which these lipid abnormalities are addressed by treatment in UK clinical practice. METHODS: The PRIMULA study was a retrospective analysis, conducted using the UK General Practice Research Database. Two periods were studied as follows: a pretreatment period, defined as the 12 months before initiation of LMT (the index date), and a follow-up period of at least 12 months. Patients included in the study (n = 25,011) had dyslipidaemia with at least one abnormal lipid measurement [total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) or triglycerides (TG)] in the pretreatment period. All patients were at high risk of cardiovascular events, which was defined as having a history of cardiovascular disease, a 10-year Framingham risk score higher than 20%, diabetes or hypertension, as defined by the Joint British Societies 2 guidelines. RESULTS: At the index date, 98% of patients were initiated on statin monotherapy. After 12 months of treatment, 15.2% (sub-group range: 11.0-22.9%) of all high-risk patients had no lipid abnormalities. The proportions of patients with high TC or LDL-C levels decreased from 98.8% to 68.9%, and from 99.2% to 68.7%, respectively, over 12 months. The prevalence of high TG levels decreased from 45.0% to 26.9%, whereas that of low HDL-C levels increased, from 16.6% to 18.0%. Risk factors for cardiovascular events were not consistently associated with the likelihood of attaining optimal lipid levels. CONCLUSIONS: Despite widespread use of statins, many individuals at high risk of cardiovascular events have persistently abnormal lipid levels, with over two-thirds of patients not achieving target levels of LDL-C or TC. Management of dyslipidaemia is therefore suboptimal in this important high-risk group in UK standard practice.

Quantitative evaluation of white matter tract DTI parameter changes in gliomas using nonlinear registration. Miller, P., Coope, D., Thompson, G., Jackson, A., & Herholz, K. NeuroImage, 60(4):2309-15, 5, 2012.
Website abstract bibtex
Website abstract bibtex Diffusion tensor imaging (DTI) has been used extensively to investigate white matter architecture in the brain. In the context of neurological disease, quantification of DTI data sets enables objective characterisation of the associated pathological changes. The aim of this study is to propose a method of evaluating DTI parameter changes in gliomas in the internal capsule using nonlinear registration to delineate the white matter and enable quantitative assessment of DTI derived parameters. 20 patients selected pre-operatively with probable grade 2 or grade 3 glioma on structural MRI along with ten normal volunteers were included in this study. DTI fractional anisotropy (FA) maps were used to define a common segmented FA skeleton that was projected back onto the original individual FA maps. Objective segment classification as normal or abnormal was achieved by comparison to prediction intervals of FA and mean diffusivity (MD) defined in normal subjects. The internal capsules of each patient were segmented into 10 regions of interest (ROI) with 20 and 16 segments across the group having significantly increased or decreased FA and MD values respectively. Seven glioma patients had abnormal DTI parameters in the internal capsule. We show that the classification of tract segments was consistent with disruption, oedema or compression. The results suggest that this method could be used to detect changes in eloquent white matter tracts in individual patients.

OBJECTIVE: This report presents bone measurement data from dual-energy X-ray absorptiometry scans of the lumbar spine and proximal femur for persons aged 8 years and over from the National Health and Nutrition Examination Survey (NHANES) 2005-2008. METHODS: Means, standard deviations, and selected percentiles were calculated for the proximal femur and lumbar spine (total and subregions) by sex, race and ethnicity, and age. Smoothed mean total lumbar spine and femur neck bone mineral density (BMD) were plotted by age, sex, and race and ethnicity. Multiple regression was used to test for significant interactions and to calculate mean total lumbar spine and femur neck BMD after adjusting for age, sex, and race and ethnicity. Differences by sex, race and ethnicity, and age were summarized by calculating the percent difference in adjusted means. RESULTS: Among scanned individuals, 11% lacked total lumbar spine data due to invalid data for one or more lumbar vertebrae, and 4% had invalid data for the proximal femur. Non-Hispanic black persons had 6% higher total lumbar spine BMD and 9%-10% higher femur neck BMD than non-Hispanic white persons. Mean total lumbar spine BMD and femur neck BMD did not differ between Mexican-American and non-Hispanic white persons in those under age 20. For those aged 20 and over, Mexican-American persons had 4% lower total lumbar spine BMD but 1% higher femur neck BMD than non-Hispanic white persons. Mean total lumbar spine BMD was 8%-17% higher in females aged 8-15 compared with males of the same age. In the age group 16-49, mean total lumbar spine BMD was similar or slightly higher for females compared with males, but after age 50 it was 60%-15% lower for females compared with males. Mean femur neck BMD was 5%-13% lower for females than males in all age groups except 12-15.

BACKGROUND: Rosacea is a chronic facial skin disease of unclear origin. Epidemiological data are scarce and controversial, with reported prevalences ranging from 0·09% to 22%. To our knowledge, incidence rates have not been quantified before. OBJECTIVES: In this observational study we quantified incidence rates of diagnosed rosacea in the U.K. and described demographic characteristics and the prevalence of ocular symptoms in patients with rosacea. We compared lifestyle factors such as smoking and alcohol consumption between patients with rosacea and controls. METHODS: Using the U.K.-based General Practice Research Database, we identified patients with an incident diagnosis of rosacea between 1995 and 2009 and matched them (1:1) to rosacea-free control patients. We assessed person-time of all patients at risk and assessed incidence rates of rosacea, stratified by age, sex, year of diagnosis and region. RESULTS: We identified 60,042 rosacea cases and 60,042 controls (61·5% women). The overall incidence rate for diagnosed rosacea in the U.K. was 1·65 per 1000 person-years. Rosacea was diagnosed in some 80% of cases after the age of 30 years. Ocular symptoms were recorded in 20·8% of cases at the index date. We observed a significantly reduced relative risk of developing rosacea among current smokers (odds ratio 0·64, 95% confidence interval 0·62-0·67). Alcohol consumption was associated with a marginal risk increase. CONCLUSIONS: We quantified incidence rates and characteristics of patients with rosacea diagnosed in clinical practice in a large epidemiological study using primary care data from the U.K. Smoking was associated with a substantially reduced risk of developing rosacea.

PURPOSE: The effect of advanced age per se versus severity of chronic and acute diseases on the short- and long-term survival of older patients admitted to the intensive care unit (ICU) remains unclear. METHODS: Intensive care unit admissions to the surgical ICU and medical ICU of patients older than 65 years were analyzed. Patients were divided into three age groups: 65-74, 75-84, and 85 and above. The primary endpoints were 28-day and 1-year mortality. RESULTS: The analysis focused on 7,265 patients above the age of 65, representing 45.7 % of the total ICU population. From the first to third age group there was increased prevalence of heart failure (25.9-40.3 %), cardiac arrhythmia (24.6-43.5 %), and valvular heart disease (7.5-15.8 %). There was reduced prevalence of diabetes complications (7.5-2.4 %), alcohol abuse (4.1-0.6 %), chronic obstructive pulmonary disease (COPD) (24.4-17.4 %), and liver failure (5.0-1.0 %). Logistic regression analysis adjusted for gender, sequential organ failure assessment, do not resuscitate, and Elixhauser score found that patients from the second and third age group had odds ratios of 1.38 [95 % confidence interval (CI) 1.19-1.59] and 1.53 (95 % CI 1.29-1.81) for 28-day mortality as compared with the first age group. Cox regression analysis for 1-year mortality in all populations and in 28-day survivors showed the same trend. CONCLUSIONS: The proportion of elderly patients from the total ICU population is high. With advancing age, the proportion of various preexisting comorbidities and the primary reason for ICU admission change. Advanced age should be regarded as a significant independent risk factor for mortality, especially for ICU patients older than 75.

OBJECTIVE: To compare clinical features of patients with remitting seronegative symmetrical synovitis with pitting edema (RS3PE) and patients with polymyalgia rheumatica (PMR) and to explore the purported association between RS3PE and malignancy. METHODS: We did a retrospective chart review of patients with RS3PE and PMR treated in a community-based hospital between January 2000 and December 2009. Outcomes assessed were clinical course of disease and associated malignancies. RESULTS: We identified 28 patients with RS3PE and 123 with pure PMR. All patients with RS3PE fulfilled PMR criteria as well. Age, comorbidity, erythrocyte sedimentation rate, duration and progression of symptoms, treatment response to initial low-dose steroids, and steroid complication rates were similar in both groups. Patients with RS3PE were more likely to be male (79% vs 41%; p = 0.001) and to have a history of smoking (39% vs 15%; p = 0.008) and a higher rate of depression (11% vs 2%; p = 0.044) at diagnosis. Among those with RS3PE, hip pain was less common (39% vs 74%; p = 0.001) than in the PMR group. No patients with RS3PE and 6 patients with pure PMR (4.9%) developed another rheumatological disease during followup. Seven of 9 patients (78%) with concurrent cancer presented slightly more frequently with systemic symptoms compared to patients without cancer (48%; p = 0.098), especially with fatigue (56% vs 22%; p = 0.037) and anorexia (33% vs 9.0%; p = 0.047). Despite rigorous cancer screening in patients with RS3PE, however, the rate of associated malignancy was not statistically different from that of patients with pure PMR [2 (7%) vs 7 (6%), respectively; p = 0.673]. CONCLUSION: Despite evidence that RS3PE is clinically distinct from PMR, we observed characteristics, treatment response, and outcomes like those expected in pure PMR. Compared to patients with pure PMR, patients with RS3PE are more likely to be male, to be depressed, and to smoke. Contrary to earlier studies, no clear association of RS3PE with malignancy was found despite rigorous cancer screening, although clinicians should be aware that patients with concurrent cancer may manifest more systemic signs and symptoms, as well as steroid resistance.

BACKGROUND: Pharmacogenetics involves complex interactions of gene products affecting pharmacodynamics and pharmacokinetics, but there is little information on the interaction of multiple genetic modifiers of drug response. Bucindolol is a β-blocker/sympatholytic agent whose efficacy is modulated by polymorphisms in the primary target (β(1) adrenergic receptor [AR] Arg389 Gly on cardiac myocytes) and a secondary target modifier (α(2C) AR Ins [wild-type (Wt)] 322-325 deletion [Del] on cardiac adrenergic neurons). The major allele homozygotes and minor allele carriers of each polymorphism are respectively associated with efficacy enhancement and loss, creating the possibility for genotype combination interactions that can be measured by clinical trial methodology. METHODOLOGY: In a 1,040 patient substudy of a bucindolol vs. placebo heart failure clinical trial, we tested the hypothesis that combinations of β(1)389 and α(2C)322-325 polymorphisms are additive for both efficacy enhancement and loss. Additionally, norepinephrine (NE) affinity for β(1)389 AR variants was measured in human explanted left ventricles. PRINCIPAL FINDINGS: The combination of β(1)389 Arg+α(2C)322-325 Wt major allele homozygotes (47% of the trial population) was non-additive for efficacy enhancement across six clinical endpoints, with an average efficacy increase of 1.70-fold vs. 2.32-fold in β(1)389 Arg homozygotes+α(2C)322-325 Del minor allele carriers. In contrast, the minor allele carrier combination (13% subset) exhibited additive efficacy loss. These disparate effects are likely due to the higher proportion (42% vs. 8.7%, P = 0.009) of high-affinity NE binding sites in β(1)389 Arg vs. Gly ARs, which converts α(2C)Del minor allele-associated NE lowering from a therapeutic liability to a benefit. CONCLUSIONS: On combination, the two sets of AR polymorphisms 1) influenced bucindolol efficacy seemingly unpredictably but consistent with their pharmacologic interactions, and 2) identified subpopulations with enhanced (β(1)389 Arg homozygotes), intermediate (β(1)389 Gly carriers+α(2C)322-325 Wt homozygotes), and no (β(1)389 Gly carriers+α(2C)322-325 Del carriers) efficacy.

These disparate effects are likely due to the higher proportion (42\% vs. 8.7\%, P = 0.009) of high-affinity NE binding sites in β(1)389 Arg vs. Gly ARs, which converts α(2C)Del minor allele-associated NE lowering from a therapeutic liability to a benefit.
CONCLUSIONS: On combination, the two sets of AR polymorphisms 1) influenced bucindolol efficacy seemingly unpredictably but consistent with their pharmacologic interactions, and 2) identified subpopulations with enhanced (β(1)389 Arg homozygotes), intermediate (β(1)389 Gly carriers+α(2C)322-325 Wt homozygotes), and no (β(1)389 Gly carriers+α(2C)322-325 Del carriers) efficacy.},

On February 4, 2008, the world's largest low emission zone (LEZ) was established. At 2644 km2, the zone encompasses most of Greater London. It restricts the entry of the oldest and most polluting diesel vehicles, including heavy-goods vehicles (haulage trucks), buses and coaches, larger vans, and minibuses. It does not apply to cars or motorcycles. The LEZ scheme will introduce increasingly stringent Euro emissions standards over time. The creation of this zone presented a unique opportunity to estimate the effects of a stepwise reduction in vehicle emissions on air quality and health. Before undertaking such an investigation, robust baseline data were gathered on air quality and the oxidative activity and metal content of particulate matter (PM) from air pollution monitors located in Greater London. In addition, methods were developed for using databases of electronic primary-care records in order to evaluate the zone's health effects. Our study began in 2007, using information about the planned restrictions in an agreed-upon LEZ scenario and year-on-year changes in the vehicle fleet in models to predict air pollution concentrations in London for the years 2005, 2008, and 2010. Based on this detailed emissions and air pollution modeling, the areas in London were then identified that were expected to show the greatest changes in air pollution concentrations and population exposures after the implementation of the LEZ. Using these predictions, the best placement of a pollution monitoring network was determined and the feasibility of evaluating the health effects using electronic primary-care records was assessed. To measure baseline pollutant concentrations before the implementation of the LEZ, a comprehensive monitoring network was established close to major roadways and intersections. Output-difference plots from statistical modeling for 2010 indicated seven key areas likely to experience the greatest change in concentrations of nitrogen dioxide (NO2) (at least 3 microg/m3) and of PM with an aerodynamic diameter \textless or = 10 microm (PM10) (at least 0.75 microg/m3) as a result of the LEZ; these suggested that the clearest signals of change were most likely to be measured near roadsides. The seven key areas were also likely to be of importance in carrying out a study to assess the health outcomes of an air quality intervention like the LEZ. Of the seven key areas, two already had monitoring sites with a full complement of equipment, four had monitoring sites that required upgrades of existing equipment, and one required a completely new installation. With the upgrades and new installations in place, fully ratified (verified) pollutant data (for PM10, PM with an aerodynamic diameter \textless or = 2.5 microm [PM2.5], nitrogen oxides [NOx], and ozone [O3] at all sites as well as for particle number, black smoke [BS], carbon monoxide [CO], and sulfur dioxide [SO2] at selected sites) were then collected for analysis. In addition, the seven key monitoring sites were supported by other sites in the London Air Quality Network (LAQN). From these, a robust set of baseline air quality data was produced. Data from automatic and manual traffic counters as well as automatic license-plate recognition cameras were used to compile detailed vehicle profiles. This enabled us to establish more precise associations between ambient pollutant concentrations and vehicle emissions. An additional goal of the study was to collect baseline PM data in order to test the hypothesis that changes in traffic densities and vehicle mixes caused by the LEZ would affect the oxidative potential and metal content of ambient PM10 and PM2.5. The resulting baseline PM data set was the first to describe, in detail, the oxidative potential and metal content of the PM10 and PM2.5 of a major city's airshed. PM in London has considerable oxidative potential; clear differences in this measure were found from site to site, with evidence that the oxidative potential of both PM10 and PM2.5 at roadside monitoring sites was higher than at urban background locations. In the PM10 samples this increased oxidative activity appeared to be associated with increased concentrations of copper (Cu), barium (Ba), and bathophenanthroline disulfonate-mobilized iron (BPS Fe) in the roadside samples. In the PM2.5 samples, no simple association could be seen, suggesting that other unmeasured components were driving the increased oxidative potential in this fraction of the roadside samples. These data suggest that two components were contributing to the oxidative potential of roadside PM, namely Cu and BPS Fe in the coarse fraction of PM (PM with an aerodynamic diameter of 2.5 microm to 10 microm; PM(2.5-10)) and an unidentified redox catalyst in PM2.5. The data derived for this baseline study confirmed key observations from a more limited spatial mapping exercise published in our earlier HEI report on the introduction of the London's Congestion Charging Scheme (CCS) in 2003 (Kelly et al. 2011a,b). In addition, the data set in the current report provided robust baseline information on the oxidative potential and metal content of PM found in the London airshed in the period before implementation of the LEZ; the finding that a proportion of the oxidative potential appears in the PM coarse mode and is apparently related to brake wear raises important issues regarding the nature of traffic management schemes. The final goal of this baseline study was to establish the feasibility, in ethical and operational terms, of using the U.K.'s electronic primary-care records to evaluate the effects of the LEZ on human health outcomes. Data on consultations and prescriptions were compiled from a pilot group of general practices (13 distributed across London, with 100,000 patients; 29 situated in the inner London Borough of Lambeth, with 200,000 patients). Ethics approvals were obtained to link individual primary-care records to modeled NOx concentrations by means of post-codes. (To preserve anonymity, the postcodes were removed before delivery to the research team.) A wide range of NOx exposures was found across London as well as within and between the practices examined. Although we observed little association between NOx exposure and smoking status, a positive relationship was found between exposure and increased socioeconomic deprivation. The health outcomes we chose to study were asthma, chronic obstructive pulmonary disease, wheeze, hay fever, upper and lower respiratory tract infections, ischemic heart disease, heart failure, and atrial fibrillation. These outcomes were measured as prevalence or incidence. Their distributions by age, sex, socioeconomic deprivation, ethnicity, and smoking were found to accord with those reported in the epidemiology literature. No cross-sectional positive associations were found between exposure to NOx and any of the studied health outcomes; some associations were significantly negative. After the pilot study, a suitable primary-care database of London patients was identified, the General Practice Research Database responsible for giving us access to these data agreed to collaborate in the evaluation of the LEZ, and an acceptable method of ensuring privacy of the records was agreed upon. The database included about 350,000 patients who had remained at the same address over the four-year period of the study. Power calculations for a controlled longitudinal analysis were then performed, indicating that for outcomes such as consultations for respiratory illnesses or prescriptions for asthma there was sufficient power to identify a 5% to 10% reduction in consultations for patients most exposed to the intervention compared with patients presumed to not be exposed to it. In conclusion, the work undertaken in this study provides a good foundation for future LEZ evaluations. Our extensive monitoring network, measuring a comprehensive set of pollutants (and a range of particle metrics), will continue to provide a valuable tool both for assessing the impact of LEZ regulations on air quality in London and for furthering understanding of the link between PM's composition and toxicity. Finally, we believe that in combination with our modeling of the predicted population-based changes in pollution exposure in London, the use of primary-care databases forms a sound basis and has sufficient statistical power for the evaluation of the potential impact of the LEZ on human health.

BACKGROUND: Previous descriptions of the epidemiology of peanut allergy have mainly been derived from small cross-sectional studies. OBJECTIVE: To interrogate a large national research database to provide estimates for the incidence, prevalence, and trends of general practitioner (GP)-recorded diagnosis of peanut allergy in the English population. METHODS: Version 10 of the QRESEARCH database was used with data from 2,958,366 patients who were registered with 422 United Kingdom general practices in the years 2001 to 2005. The primary outcome was a recording of clinician-diagnosed peanut allergy. RESULTS: The age-sex standardized incidence rate of peanut allergy in 2005 was 0.08 per 1000 person-years (95% CI, 0.07-0.08), and the prevalence rate was 0.51 per 1000 patients (95% CI, 0.49-0.54). This translated into an estimated 4000 incident cases (95% CI, 3500-4600) and 25,700 prevalent cases (95% CI, 24,400-27,100) of GP-recorded diagnosis of peanut allergy in England in 2005. During the study period, the incidence rate of peanut allergy remained fairly stable, whereas the prevalence rate doubled. In those under 18 years of age, the crude lifetime prevalence rate was higher in males than females. A significant inverse relationship between prevalence and socioeconomic status was found. CONCLUSION: These data on GP-recorded diagnosis of peanut allergy from a large general practice database suggest a much lower prevalence in peanut allergy than has hitherto been found. This difference may in part be explained by underrecording of peanut allergy in general practice. Further research is needed to assess the true frequency of peanut allergy in the population and whether there has been a true increase in recent years.

Adults ask children questions in a variety of contexts, for example, in the classroom, in the forensic context, or in experimental research. In such situations children will inevitably be asked some questions to which they do not know the answer, because they do not have the required information ("unanswerable" questions). When asked unanswerable questions, it is important that children indicate that they do not have the required information to provide an answer. These 2 studies investigated whether preinterview instructions (Experiment 1) or establishing a memory narrative (Experiment 2) helped children correctly indicate a lack of knowledge to unanswerable questions. In both studies, 6- and 8-year-olds participated in a classroom-based event about which they were subsequently interviewed. Some of the questions were answerable, and some were unanswerable. Results showed that preinterview instructions increased the number of younger children's appropriate "don't know" responses to unanswerable questions, without decreasing correct responses to answerable questions. This suggests that demand characteristics affect children's tendency correctly to say "I don't know." The opportunity to provide a narrative account increased children's appropriate "don't know" responses to unanswerable yes/no questions, and increased the number of younger children's correct responses to answerable questions. This suggests that cognitive factors also contribute to children's tendency correctly to say "I don't know." These results have implications for any context where adults need to obtain information from children through questioning, for example, a health practitioner asking about a medical condition, in classroom discourse, in the investigative interview, and in developmental psychology research.

}Concurrent drug use and the risk of perforated colonic diverticular disease: a population-based case-control study. Humes, D. J., Fleming, K. M., Spiller, R. C., & West, J. Gut, 60(2):219--224, February, 2011.
doi abstract bibtex
doi abstract bibtex
OBJECTIVE: To determine the risk of diverticular perforation associated with current and ever use of corticosteroids, opiate analgesics, non-steroidal anti-inflammatory drugs, aspirin, cyclo-oxygenase-2 inhibitors, statins and calcium antagonists. DESIGN, SETTING AND PARTICIPANTS: Case-control analysis using conditional logistic regression analysis of data from the UK General Practice Research Database. The study involved 899 cases of incident diverticular perforation and 8980 population controls from 1990 to 2005. MAIN OUTCOME MEASURES: Odds ratios (ORs) are presented for perforation associated with use of corticosteroids, opiate analgesics, non-steroidal anti-inflammatory drugs, aspirin, cyclo-oxygenase-2 inhibitors, statins and calcium antagonists. Data were adjusted for smoking, comorbidity, prior abdominal pain and body mass index. RESULTS: A total of 899 patients with an incident diagnosis of perforated diverticular disease were identified. Current use of opiate analgesics (OR=2.16; 95% CI 1.55 to 3.01) and oral corticosteroids (OR=2.74; 95% CI 1.63 to 4.61) was associated with a two- and threefold increase in the risk of diverticular perforation, respectively. Current use of a calcium antagonist and aspirin were not associated with an increased risk of diverticular perforation. Current statin use was associated with a reduction in the risk of perforation (OR=0.44; 95% CI 0.20 to 0.95). CONCLUSION: Perforated diverticular disease is a serious surgical emergency with current opiate analgesics and oral corticosteroids being strongly associated with an increased risk of diverticular perforation.

BACKGROUND: Clinical trials suggest that thiazolidinediones (TZDs) may increase the risk of congestive heart failure (CHF). However, their effect on the risk of incident CHF in unselected populations has not been thoroughly investigated. METHODS: Using data from the UK's General Practice Research Database, we conducted a case-control study within a population-based cohort of patients with type 2 diabetes. Cases were identified by a clinical diagnosis of incident CHF and were then classified as possible or probable cases using prescription data. A 90-day drug exposure window was used in the primary analysis, which compared patients prescribed TZDs with those with no prescriptions for anti-diabetic medications. RESULTS: We identified 3405 incident cases (2632 probable and 773 possible) of CHF and 32,042 corresponding controls. TZDs were prescribed in 6.4% of cases and 6.3% of controls. Prescription of TZDs was associated with an increased rate of possible or probable CHF (adjusted rate ratio (RR) = 1.24, 95% CI = 1.01, 1.54 and adjusted RR = 1.24, 95% CI = 0.98, 1.58, respectively). Similar results were obtained when using a 180-day exposure window (RR = 1.38, 95% CI = 1.11, 1.72 and RR = 1.44, 95% CI = 1.12, 1.84, respectively). CONCLUSIONS: Given the totality of the evidence from this and previous studies, the probability of an increased risk for CHF with these agents remains high. However, any increase in CHF risk associated with TZDs may be lower than previously reported.

BACKGROUND: Endometriosis is estimated to affect 1 in 10 women during the reproductive years. There is often delay in making the diagnosis, mainly due to the non-specific nature of the associated symptoms and the need to verify the disease surgically. A biomarker that is simple to measure could help clinicians to diagnose (or at least exclude) endometriosis; it might also allow the effects of treatment to be monitored. If effective, such a marker or panel of markers could prevent unnecessary diagnostic procedures and/or recognize treatment failure at an early stage. METHODS: We used QUADAS (Quality Assessment of Diagnostic Accuracy Studies) criteria to perform a systematic review of the literature over the last 25 years to assess critically the clinical value of all proposed biomarkers for endometriosis in serum, plasma and urine. RESULTS: We identified over 100 putative biomarkers in publications that met the selection criteria. We were unable to identify a single biomarker or panel of biomarkers that have unequivocally been shown to be clinically useful. CONCLUSIONS: Peripheral biomarkers show promise as diagnostic aids, but further research is necessary before they can be recommended in routine clinical care. Panels of markers may allow increased sensitivity and specificity of any diagnostic test.

Website abstract bibtex Although investigations of memory and the dynamics of ERP components and neural oscillations as assessed through EEG have been well utilized, little research into the volitional nature of suppression over memory retrieval have used these methods. Oscillation analyses conducted on the Think/No-Think (TNT) task and volitional suppression of retrieval are of interest to broaden our knowledge of neural oscillations associated not only during successful memory retrieval but also when retrieval is unwanted or suppressed. In the current study, we measured EEG during a TNT task and performed ERP and EEG spectral power band analyses. ERP results replicated other researchers' observations of increases in 500-800 msec parietal effects for items where retrieval was instructed to be elaborated compared with being suppressed. Furthermore, EEG analyses indicated increased alpha (8-12 Hz) and theta (3-8 Hz) oscillations across parietal electrodes for items that were instructed to be suppressed versus those to be elaborated. Additionally, during the second half of the experiment (after repeated attempts at control), increases in theta oscillations were found across both frontal and parietal electrodes for items that were instructed to be suppressed and that were ultimately forgotten versus those ultimately remembered. Increased alpha power for items that were instructed to be suppressed versus elaborated may indicate reductions of retrieval attempts or lack of retrieval success. Increased theta power for items that were instructed to be suppressed versus elaborated may indicate increased or prolonged cognitive control to monitor retrieval events.

doi abstract bibtex
doi abstract bibtex
OBJECTIVE: To derive and validate risk algorithms so that the risks of four clinical outcomes associated with statin use can be estimated for individual patients. DESIGN: Prospective open cohort study using routinely collected data from 368 QResearch general practices in England and Wales to develop the scores. The scores were validated using two separate sets of practices-188 separate QResearch practices and 364 practices contributing to the THIN database. SUBJECTS: In the QResearch derivation cohort 225 922 new users of statins and 1 778 770 non-users of statins were studied. In the QResearch validation cohort 118 372 statin users and 877 812 non-users of statins were studied. In the THIN validation cohort, we studied 282 056 statin users and 1 923 840 non-users of statins were studied. METHODS: Cox proportional hazards models in the derivation cohort to derive risk equations. Measures of calibration and discrimination in both validation cohorts. OUTCOMES: 5-Year risk of moderate/serious myopathic events; moderate/serious liver dysfunction; acute renal failure and cataract. RESULTS: The performance of three of the risk prediction algorithms in the THIN cohort was very good. For example, in women, the algorithm for moderate/serious myopathy explained 42.15% of the variation. The corresponding D statistics was 1.75. The acute renal failure algorithm explained 59.62% of the variation (D statistic=2.49). The cataract algorithm explained 59.14% of the variation (D statistic=2.46). The algorithms to predict moderate/severe liver dysfunction only explained 15.55% of the variation (D statistics=0.89). The performance of each algorithm was similar for both sexes when tested on the QResearch validation cohort. CONCLUSIONS: The algorithms to predict acute renal failure, moderate/serious myopathy and cataract could be used to identify patients at increased risk of these adverse effects enabling patients to be monitored more closely. Further research is needed to develop a better algorithm to predict liver dysfunction.

doi abstract bibtex
doi abstract bibtex
BACKGROUND: Endometriomata are cysts of endometriosis in the ovaries. As artificial reproductive technology (ART) cycles involve oocyte pickup from the ovaries, endometriomata may interfere with the outcome of ART. OBJECTIVES: To determine the effectiveness and safety of surgery, medical treatment, combination therapy or no treatment for improving reproductive outcomes among women with endometriomata, prior to undergoing ART cycles. SEARCH STRATEGY: The review authors searched: Cochrane Menstrual Disorders and Subfertility Group Specialised Register of trials, CENTRAL (The Cochrane Library), EMBASE, MEDLINE, PubMed, PsycINFO, CINAHL, DARE, trial registers for ongoing and registered trials, citation indexes, conference abstracts on the ISI Web of Knowledge, Clinical Study Results, OpenSIGLE (July 2010) and handsearched Fertility and Sterility (2008 to 2010). SELECTION CRITERIA: Randomised controlled trials of any medical, surgical or combination therapy or expectant management for endometriomata prior to ART. DATA COLLECTION AND ANALYSIS: The trials were independently identified and assessed for risk of bias by two authors. The authors of the trials that were potentially eligible for inclusion were contacted for additional information. Outcomes were expressed as Peto odds ratios and mean differences (MD). MAIN RESULTS: Eleven trials were identified of which seven were excluded and four with 312 participants were included.No trial reported live birth outcomes. One trial compared gonadotropin-releasing hormone (GnRH) agonist with GnRH antagonist. There was no evidence of a difference for clinical pregnancy rate (CPR), however the number of mature oocytes retrieved (NMOR) was greater with GnRH agonists (MD -1.60, 95% CI -2.44 to -0.76) and the ovarian response was increased (estradiol (E2) levels on day of human chorionic gonadotropin (hCG) injection) (MD -456.30, 95% CI -896.06 to -16.54).Surgery (aspiration or cystectomy) versus expectant management (EM) showed no evidence of a benefit for clinical pregnancy with either technique. Aspiration was associated with greater NMOR (MD 0.50, 95% CI 0.02 to 0.98) and increased ovarian response (E2 levels on day of hCG injection) (MD 685.3, 95% CI 464.50 to 906.10) compared to EM.Cystectomy was associated with a decreased ovarian response to controlled ovarian hyperstimulation (COH) (MD -510.00, 95% CI -676.62 to -343.38); no evidence of an effect on the NMOR compared to EM. Aspiration versus cystectomy showed no evidence of a difference in CPR or the NMOR. AUTHORS' CONCLUSIONS: There was no evidence of an effect on reproductive outcomes in any of the four included trials. Further RCTs of management of endometrioma in women undergoing ART are required.

AIM: Little is known about pyridoxine nutriture of children treated with isoniazid (INH) regimens. This study documents plasma pyridoxal 5'-phosphate (PLP) concentrations in children, HIV-infected and HIV-uninfected, receiving INH regimens. METHODS: Children from the Western Cape of South Africa hospitalized for tuberculosis (TB) management were studied. Plasma PLP concentrations were determined on enrolment, 1-month after commencing TB treatment, and again after 4-month's treatment. The children received a supplement meeting pyridoxine requirements. RESULTS: Nineteen HIV-infected and 33 HIV-uninfected children received INH (dosage range 4-20 mg/kg) daily. Mean PLP plasma concentrations on enrolment were 8.32 (SD 6.75) ng/mL and 11.28 (SD 3.02) ng/mL in HIV-infected and HIV-uninfected children, respectively (p = 0.11) and after 4-month's treatment 6.75 (SD 2.71) ng/mL and 14.76 (SD 7.96) ng/mL (p \textless 0.001). On enrolment 9 (50%) HIV-infected and 5 (15%) HIV-uninfected children (p = 0.016) had suboptimal PLP concentrations (\textless6 ng/mL); after 4-month's treatment 8 (42%) and 2 (6%) (p = 0.004). CONCLUSION: Plasma PLP concentrations in children treated for TB were low on enrolment in HIV-infected and HIV-uninfected children; after 4-month's treatment low values were still common in HIV-infected children. Additional pyridoxine supplementation of malnourished children treated for tuberculosis is advisable, particularly those HIV-infected.

Quite apart from studies of rare disease events illustrating the importance of key genes in humans and animals, TB at the population level is also influenced by the genetics of the host. Heritability of disease concordance and immune responses to mycobacterial antigens has been clearly shown, and ranges up to 71%. Linkage studies, designed to identify major susceptibility genes in a disease, have produced a number of candidate loci but few, except for regions on chromosome 5p15, 20p and 20q, have been replicated. The region on 5p15 regulates the intensity of the response to the tuberculin skin test, and another locus on 11p14 appears to control resistance to the bacterium. In addition, numerous genes and pathways have been implicated in candidate gene association studies, with validation of polymorphisms in IFNG, NRAMP1, and NOS2A and equivocal results for IL10, CCL2, DC-SIGN, P2RX7, VDR, TLR2, TLR9 and SP110. Other more recently researched candidate genes such as TNFRSF1B remain to be validated, preferably in meta-analyses. New approaches have provided early evidence for the importance of gene-gene interactions in regulating resistance to disease, and also the prospect that applying host genetics in the field of vaccinomics could lead to a more targeted approach in designing interventions to aid the human immune system in combating mycobacteria. Genome-wide association studies and admixture mapping are approaches that remain to be applied to TB, and it is not clear, as is the case with other complex diseases, how much of the heritability of the TB susceptibility phenotype will be determined by multiple genes of small effect versus rare variants with disproportionately large effects.

The standardized bone mineral density (sBMD) values, derived using universal standardized equations, were shown to be equivalent within 1.0% for hip but significantly different for spine for state-of-art fan-beam dual X-ray absorptiometry (DXA) Hologic and GE-Lunar systems. Spine L1-L4 and L2-L4 sBMD mean differences between the two systems were 0.042 g/cm(2) (4.1%) and 0.035 g/cm(2) (3.2%), respectively. INTRODUCTION: The objective of this study is to validate the 1994 pencil-beam DXA "universal standardization equations" for state-of-the-art fan-beam DXA systems. METHODS: The spine and bilateral femurs of 87 postmenopausal women were scanned on both Hologic Delphi and GE-Lunar Prodigy DXA systems at three different clinical centers. The scans were analyzed using Hologic Apex and GE-Lunar EnCore software. The BMD results were converted to sBMD using the equations previously developed. Linear regression analysis was used to describe the relationship of the two systems' BMD results. Bland-Altman analysis was used to assess the differences in measures. RESULTS: The Apex and Prodigy sBMD values were highly correlated (r ranged from 0.92 to 0.98). Spine L1-L4 and L2-L4 sBMD values had significant intercepts and slopes for Bland-Altman regression, with mean differences of 0.042 g/cm(2) (4.1%) and 0.035 g/cm(2) (3.2%), respectively. The total hip and neck sBMD showed no significant intercept and slope, except left total sBMD had a significant difference between the two systems of 0.009 g/cm(2) (1.0%). CONCLUSIONS: The sBMD values were shown to be equivalent within 1.0% for hip but were significantly different for spine on the two systems. Biases may persist in pooled sBMD data from different manufacturers, and further study is necessary to determine the cause.

AIMS: Psoriasis is a common chronic inflammatory T-helper cell-1/17 mediated skin disease. Recent studies suggest that psoriasis, particularly if severe, may be an independent risk factor for atherosclerosis, myocardial infarction (MI), and stroke. We conducted a cohort study using the General Practice Research Database to determine if severe psoriasis patients have an increased risk of cardiovascular (CV) mortality. METHODS AND RESULTS: Severe psoriasis was defined as patients who received a psoriasis diagnosis and systemic therapy consistent with severe psoriasis (n = 3603). Up to four unexposed patients without psoriasis were selected from the same practices and start dates for each psoriasis patient (n = 14 330). For every death, the cause was determined by review of the electronic medical record. Severe psoriasis was an independent risk factor for CV mortality (HR 1.57; 95% CI 1.26, 1.96) when adjusting for age, sex, smoking, diabetes, hypertension, and hyperlipidaemia. Overall, severe psoriasis patients experienced one extra CV death per 283 patients per year, even when adjusting for major CV risk factors. The relative risk of CV mortality was modified by age. For example, the RR of CV death for a 40-year-old and 60-year-old with severe psoriasis was 2.69 (1.45, 4.99) and 1.92 (1.41, 2.62), respectively. The findings were robust to multiple sensitivity analyses. CONCLUSION: Patients with severe psoriasis have an increased risk of CV mortality that is independent of traditional CV risk factors. Additional studies are needed to determine the mechanism of this association and the impact that control of psoriasis has on CV risk.

The effect of CO2 acidified sea water and reduced salinity on aspects of the embryonic development of the amphipod Echinogammarus marinus (Leach). Egilsdottir, H., Spicer, J., I., & Rundle, S., D. Marine pollution bulletin, 58(8):1187-91, Elsevier Ltd, 8, 2009.
Paper Website abstract bibtex
Paper Website abstract bibtex We investigated the effect of CO(2) acidified sea water (S=35, 22 and 10(PSU)) on embryonic development of the intertidal amphipod Echinogammarus marinus (Leach). Low pH, but not low salinity (22(PSU)), resulted in a more protracted embryonic development in situ although the effect was only evident at low salinity. However reduced salinity, not pH, exerted a strong significant effect, on numbers and calcium content of hatchlings. Females exposed to low salinity (10(PSU)) did not carry eggs through to hatching. There was no significant difference in the number of viable hatchlings between females cultured in 22 and 35(PSU) but the exoskeleton of the juveniles at 22(PSU) contained significantly less calcium. Ocean acidification may affect aspects of E. marinus development but exposure to realistic low salinities appear, in the short term, to be more important in impacting development than exposure to CO(2) acidified sea water at levels predicted for 300 years time.

Paper abstract bibtex
Paper abstract bibtex This study focuses on analysis of the relationship between changes in blood oxygen saturation (SaO(2)) and heart rate (HR) recordings from nocturnal pulse oximetry (NPO) in patients suspected of suffering from obstructive sleep apnoea (OSA) syndrome. Two different analyses were developed: a classical frequency analysis based on the magnitude squared coherence (MSC) and a nonlinear analysis by means of a recently developed measure of synchrony, the cross-approximate entropy (cross-ApEn). A data set of 187 subjects was studied. We found significantly higher correlation and synchrony between oximetry signals from OSA positive patients compared with OSA negative subjects. We assessed the diagnostic ability to detect OSA syndrome of both the classical and nonlinear approaches by means of receiver operating characteristic (ROC) analyses with tenfold cross-validation. The nonlinear measure of synchrony significantly improved the results obtained with classical MSC: 69.2% sensitivity, 90.9% specificity and 78.1% accuracy were reached with MSC, whereas 83.7% sensitivity, 84.3% specificity and 84.0% accuracy were obtained with cross-ApEn. Our results suggest that the use of nonlinear measures of synchrony could provide essential information from oximetry signals, which cannot be obtained with classical spectral analysis.

OBJECTIVE: To evaluate the impact of rofecoxib withdrawal on the characteristics of patients prescribed selective cyclooxygenase 2 (COX-2) inhibitors. METHODS: The General Practice Research Database was used to identify patients age \textgreater or =18 years who were prescribed a selective COX-2 inhibitor. Various patient characteristics were noted at the start of therapy: age, sex, nonsteroidal antiinflammatory drug-related risk factors for upper gastrointestinal (GI) events, and the Framingham risk score for cardiovascular disease. Logistic regression was used to compare patients using selective COX-2 inhibitors before and after September 2004. RESULT: The study population included 171,645 patients receiving selective COX-2 inhibitors. The number of users substantially increased over time until September 2004 and sharply declined thereafter. Approximately 80% stopped selective COX-2 inhibitor therapy within 6 months. Patients receiving selective COX-2 inhibitors after September 2004 were younger and included more men compared with those receiving therapy before September 2004. There was no change before and after September 2004 in the proportion of patients with GI risk factors or high Framingham risk scores, after adjustment for age and sex. A correlation was found between presence of GI risk factors and high Framingham risk scores. Only 20% of patients receiving selective COX-2 inhibitors had GI risk factors but low Framingham risk score, which did not change after September 2004. CONCLUSION: There was no channeling in the usage of selective COX-2 inhibitors toward patients with a high risk of GI and low risk of cardiovascular disease following the withdrawal of rofecoxib.

Website abstract bibtex BACKGROUND: Health-related quality of life (HRQOL) and other patient-reported outcomes (PROs) are important in evaluating the impact of psoriasis and its treatment. OBJECTIVES: To assess the impact of adalimumab treatment on HRQOL and other PROs in patients with moderate to severe psoriasis. METHODS: A 16-week, double-blind, double-dummy, randomized controlled trial evaluated the efficacy and safety of adalimumab in 271 adults with moderate to severe chronic plaque psoriasis. Patients were randomized in a 2:2:1 ratio to adalimumab, methotrexate (MTX) or placebo. PROs were evaluated throughout the study and included the Dermatology Life Quality Index (DLQI), Patient's Global Assessment of disease severity, plaque psoriasis and psoriatic arthritis pain visual analogue scale (VAS), Psoriasis-Related Pruritus Assessment and EuroQOL 5D (EQ-5D). RESULTS: Statistically significant differences were observed between the adalimumab- and placebo-treated and the MTX-treated groups on mean DLQI total scores during the 16-week double-blind study (both P<0.001). Significant differences, favouring adalimumab compared with placebo, were also observed on the Patient's Global Assessment of disease severity (P<0.001), VAS for pain (P<0.001), Psoriasis-Related Pruritus Assessment (P<0.001), EQ-5D VAS (P<0.001) and EQ-5D index score (P<0.01). Compared with MTX, adalimumab resulted in statistically significantly greater improvements in the Patient's Global Assessment of disease severity (P<0.001), the VAS for pain (P<0.01) and the Psoriasis-Related Pruritus Assessment (P<0.001). CONCLUSIONS: Adalimumab was efficacious in improving dermatology-specific HRQOL, disease control and symptom outcomes in patients with moderate to severe psoriasis.

abstract = {BACKGROUND: Health-related quality of life (HRQOL) and other patient-reported outcomes (PROs) are important in evaluating the impact of psoriasis and its treatment. OBJECTIVES: To assess the impact of adalimumab treatment on HRQOL and other PROs in patients with moderate to severe psoriasis. METHODS: A 16-week, double-blind, double-dummy, randomized controlled trial evaluated the efficacy and safety of adalimumab in 271 adults with moderate to severe chronic plaque psoriasis. Patients were randomized in a 2:2:1 ratio to adalimumab, methotrexate (MTX) or placebo. PROs were evaluated throughout the study and included the Dermatology Life Quality Index (DLQI), Patient's Global Assessment of disease severity, plaque psoriasis and psoriatic arthritis pain visual analogue scale (VAS), Psoriasis-Related Pruritus Assessment and EuroQOL 5D (EQ-5D). RESULTS: Statistically significant differences were observed between the adalimumab- and placebo-treated and the MTX-treated groups on mean DLQI total scores during the 16-week double-blind study (both P<0.001). Significant differences, favouring adalimumab compared with placebo, were also observed on the Patient's Global Assessment of disease severity (P<0.001), VAS for pain (P<0.001), Psoriasis-Related Pruritus Assessment (P<0.001), EQ-5D VAS (P<0.001) and EQ-5D index score (P<0.01). Compared with MTX, adalimumab resulted in statistically significantly greater improvements in the Patient's Global Assessment of disease severity (P<0.001), the VAS for pain (P<0.01) and the Psoriasis-Related Pruritus Assessment (P<0.001). CONCLUSIONS: Adalimumab was efficacious in improving dermatology-specific HRQOL, disease control and symptom outcomes in patients with moderate to severe psoriasis.},

}The ethics of direct and indirect referral for termination of pregnancy. Chervenak, A, F., McCullough, & B, L. American journal of obstetrics and gynecology, 199(3):232.e1--3, September, 2008.
doi abstract bibtex

Referral of pregnant patients for termination of pregnancy by physicians morally opposed to the procedure is ethically controversial, with polarized positions taken by physician organizations. Based on the ethical principles of beneficence and respect for autonomy, we establish the distinction between direct and indirect referral. Direct referral is beneficence based and requires the referring physician to ensure that the referral occurs. Indirect referral is autonomy based, with a beneficence-based component that requires that the physician provide information to the patient about health care organizations that will provide competent medical care. We show that only indirect referral is ethically required in healthy women for termination of an unwanted pregnancy or a pregnancy complicated by fetal anomalies because the indications for this procedure are solely autonomy based. Direct referral for termination of pregnancy is not ethically required but is permissible. Conscience-based objections to direct referral for termination of pregnancy have merit; conscience-based objections to indirect referral do not.

This research focuses on the relation between color and psychological functioning, specifically, that between red and performance attainment. Red is hypothesized to impair performance on achievement tasks, because red is associated with the danger of failure in achievement contexts and evokes avoidance motivation. Four experiments demonstrate that the brief perception of red prior to an important test (e.g., an IQ test) impairs performance, and this effect appears to take place outside of participants' conscious awareness. Two further experiments establish the link between red and avoidance motivation as indicated by behavioral (i.e., task choice) and psychophysiological (i.e., cortical activation) measures. The findings suggest that care must be taken in how red is used in achievement contexts and illustrate how color can act as a subtle environmental cue that has important influences on behavior.

Website abstract bibtex Multiple sclerosis (MS) is a common inflammatory disease of the central nervous system unsurpassed for its variability in disease outcome. Apolipoprotein E (APOE) is involved in neuronal remodelling and several studies have attempted to examine the effect of APOE on MS disease severity, but its function in modifying the course of MS is controversial. It has been suggested recently that PVRL2, not APOE, is the locus on chromosome 19 which influences clinical outcome of MS. A cohort of sporadic MS cases, taken from opposite extremes of the putative distribution of long-term outcome using the most stringent clinical criteria to date, was used to determine the role of APOE and PVRL2 on MS disease severity. The MS cases selected represent the prognostic best 5% (benign MS) and worst 5% (malignant MS) of cases in terms of clinical outcome assessed by the EDSS. Genotyping the two sets of MS patients (112 benign and 51 malignant) and a replication cohort from Sardinia provided no evidence to suggest that APOE or PVRL2 have any outcome modifying activity. We conclude that APOE and PVRL2 have little or no effect on the clinical outcome of MS.

BACKGROUND: Current guidelines for post-mastectomy radiotherapy (PMRT) derive largely from extrapolating information from multicentre trials. The aim of this study was to describe outcomes of patients who underwent mastectomy without radiotherapy in a single institution. PATIENTS AND METHODS: 650 patients had total mastectomy and axillary dissection without PMRT between 1997 and 2001. Median follow-up was 65 months. RESULTS: 5-year cumulative incidence of loco-regional recurrence (LRR) was 6.8% (3.0, 8.1, 9.9% in node negative, 1-3, \textgreater or =4 positive nodes, respectively). At the multivariate analysis, positive lymph nodes and endocrine non-responsive tumours were found to shorten LRR disease-free survival. In patients with positive hormone receptors, 5-year cumulative incidence of LRR disease-free survival were 2.3%, 7.6% and 7.6% for node negative, 1-3 and \textgreater or =4 positive lymph nodes, respectively. The same figures were 5.9%, 10.3% and 20.0% in patients with endocrine non-responsive tumours. CONCLUSIONS: patients with endocrine-responsive tumours treated by mastectomy and complete (level III) axillary dissection have a low risk of LRR even if four or more positive lymph nodes are involved, thus giving rise to doubts on the use of PMRT in this subset of patients. On the other hand, PMRT might play a role for patients with negative hormone receptors and four or more positive nodes.

}Prefrontal regions orchestrate suppression of emotional memories via a two-phase process. Depue, B., E., Curran, T., & Banich, M., T. Science (New York, N.Y.), 2007.
abstract bibtex
abstract bibtex
Whether memories can be suppressed has been a controversial issue in psychology and cognitive neuroscience for decades. We found evidence that emotional memories are suppressed via two time-differentiated neural mechanisms: (i) an initial suppression by the right inferior frontal gyrus over regions supporting sensory components of the memory representation (visual cortex, thalamus), followed by (ii) right medial frontal gyrus control over regions supporting multimodal and emotional components of the memory representation (hippocampus, amygdala), both of which are influenced by fronto-polar regions. These results indicate that memory suppression does occur and, at least in nonpsychiatric populations, is under the control of prefrontal regions.

BACKGROUND: Since the mid-1990s, the development of new oral antidiabetic agents (OAs) and treatment guidelines have created an opportunity to improve glycemic control in patients with type 2 diabetes. OBJECTIVES: This study aimed to assess the prevalence of good and inadequate glycemic control across a 5-year period among patients with diabetes in the United Kingdom. It also investigated the factors associated with achieving glycemic targets. METHODS: This was a retrospective, cross-sectional analysis of data from the General Practice Research Database. Three limits were used to assess glycosylated hemoglobin (HbA1c): 6.5%, 7.0%, or 7.5%. Values above the cutoffs indicated inadequate control of HbA1c; those at or below the cutoffs indicated good control. The study evaluated clinical and pharmacy data from the years 1998 to 2002 for patients with type 2 diabetes, \textgreater or =2 years of follow-up, and \textgreater or =2 HbA1c measurements during the first year. Five independent cross-sectional analyses were conducted, grouping data by year. Statistical significance was determined by Student t and chi2 tests. RESULTS: Data were analyzed for 10,663 patients aged 17 to 98 years. The number of total eligible type 2 diabetes patients increased over the course of the study period: 5674 patients in 1998, 6553 in 1999, 7314 in 2000, 7323 in 2001, and 6192 in 2002. Overall, the study population had a mean (SD) age of 66 (11.0) years, was 53% male (3033/5674), and had a body mass index of 29 kg/m(2). Seventy-six percent of patients had HbA1c \textgreater7.0% and 37% were taking \textgreater or =2 oral agents. In 1998 and 2002, 79% (4482/5674) and 76% (4732/6192) of patients, respectively, had inadequate glycemic control, defined as HbA1c \textgreater7.0%. When defined as HbA1c \textgreater7.5%, 69% (3923/5674) and 62% (3814/6192) of patients, respectively, had inadequate control. Finally, when defined as HbA1c \textgreater6.5%, 88% (5011/5674) of patients in both 1998 and 2002 had inadequate control. Compared with patients with good disease control (HbA1c \textless or =7.0%), patients with inadequate control were approximately 2 years younger (P \textless 0.001) and had been prescribed more OAs: 41% received \textgreater or =2 OAs in 1998 and 52% in 2002, compared with 23% and 34% (both, P = 0.001), respectively, of patients with good glycemic control (P \textless 0.02). Sex, number of diabetes complications, and number of comorbidities did not differ between groups (P = NS). CONCLUSIONS: Despite the introduction of new OAs and treatment guidelines, the prevalence of inadequate glycemic control remains high (\textgreater60%) in patients with type 2 diabetes in the United Kingdom. Regardless of the HbA1c cutoff, patients with inadequate control were younger and received prescriptions for more OAs than patients with good control.

abstract = {BACKGROUND: Since the mid-1990s, the development of new oral antidiabetic agents (OAs) and treatment guidelines have created an opportunity to improve glycemic control in patients with type 2 diabetes.
OBJECTIVES: This study aimed to assess the prevalence of good and inadequate glycemic control across a 5-year period among patients with diabetes in the United Kingdom. It also investigated the factors associated with achieving glycemic targets.
METHODS: This was a retrospective, cross-sectional analysis of data from the General Practice Research Database. Three limits were used to assess glycosylated hemoglobin (HbA1c): 6.5\%, 7.0\%, or 7.5\%. Values above the cutoffs indicated inadequate control of HbA1c; those at or below the cutoffs indicated good control. The study evaluated clinical and pharmacy data from the years 1998 to 2002 for patients with type 2 diabetes, {\textgreater} or =2 years of follow-up, and {\textgreater} or =2 HbA1c measurements during the first year. Five independent cross-sectional analyses were conducted, grouping data by year. Statistical significance was determined by Student t and chi2 tests.
RESULTS: Data were analyzed for 10,663 patients aged 17 to 98 years. The number of total eligible type 2 diabetes patients increased over the course of the study period: 5674 patients in 1998, 6553 in 1999, 7314 in 2000, 7323 in 2001, and 6192 in 2002. Overall, the study population had a mean (SD) age of 66 (11.0) years, was 53\% male (3033/5674), and had a body mass index of 29 kg/m(2). Seventy-six percent of patients had HbA1c {\textgreater}7.0\% and 37\% were taking {\textgreater} or =2 oral agents. In 1998 and 2002, 79\% (4482/5674) and 76\% (4732/6192) of patients, respectively, had inadequate glycemic control, defined as HbA1c {\textgreater}7.0\%. When defined as HbA1c {\textgreater}7.5\%, 69\% (3923/5674) and 62\% (3814/6192) of patients, respectively, had inadequate control. Finally, when defined as HbA1c {\textgreater}6.5\%, 88\% (5011/5674) of patients in both 1998 and 2002 had inadequate control. Compared with patients with good disease control (HbA1c {\textless} or =7.0\%), patients with inadequate control were approximately 2 years younger (P {\textless} 0.001) and had been prescribed more OAs: 41\% received {\textgreater} or =2 OAs in 1998 and 52\% in 2002, compared with 23\% and 34\% (both, P = 0.001), respectively, of patients with good glycemic control (P {\textless} 0.02). Sex, number of diabetes complications, and number of comorbidities did not differ between groups (P = NS).
CONCLUSIONS: Despite the introduction of new OAs and treatment guidelines, the prevalence of inadequate glycemic control remains high ({\textgreater}60\%) in patients with type 2 diabetes in the United Kingdom. Regardless of the HbA1c cutoff, patients with inadequate control were younger and received prescriptions for more OAs than patients with good control.},

Paper Website abstract bibtex Eggs of seabirds have routinely been used as indicators of environmental pollution in the Arctic. However, the variability in organohalogen concentration and composition associated with the laying sequence, have not been defined. We examined a suite of PCBs, organochlorine (OC) pesticides and by-products, polybrominated diphenyl ethers (PBDEs), polybrominated biphenyls (PBBs) and methylsulfonyl- (MeSO2) PCBs in complete 3-egg clutches of glaucous gulls (Larus hyperboreus), and plasma samples of the laying females collected from the Norwegian Arctic. SigmaPCB, SigmaOC and SigmaPBDE, but not SigmaMeSO2-PCB, concentrations in eggs were positively associated, with increasing magnitude and significance from the first through the last-laid egg, with concentrations in female plasma. However, the concentrations of these organohalogen classes fluctuated irrespective of the laying order in the clutch. In general, maternal transfer favored low K(ow) and/or less persistent compounds, whereas the recalcitrant and/or higher-halogenated compounds were less readily transferred, and consequently more selectively retained in the mother.

INTRODUCTION: Precision error in bone mineral density (BMD) measurement can be affected by patient positioning, variations in scan analysis, automation of software, and both short- and long-term fluctuations of the densitometry equipment. Minimization and characterization of these errors is essential for reliable assessment of BMD change over time. METHODS: We compared the short-term precision error of two dual-energy X-ray absorptiometry (DXA) devices: the Lunar Prodigy (GE Healthcare) and the Delphi (Hologic). Both are fan-beam DXA devices predominantly used to measure BMD of the spine and proximal femur. In this study, 87 women (mean age 61.6+/-8.9 years) were measured in duplicate, with repositioning, on both systems, at one of three clinical centers. The technologists were International Society for Clinical Densitometry (ISCD) certified and followed manufacturer-recommended procedures. All scans were acquired using 30-s scan modes. Precision error was calculated as the root-mean-square standard deviation (RMS-SD) and coefficient of variation (RMS-%CV) for the repeated measurements. Right and left femora were evaluated individually and as a combined dual femur precision. Precision error of Prodigy and Delphi measurements at each measurement region was compared using an F test to determine significance of any observed differences. RESULTS: While precision errors for both systems were low, Prodigy precision errors were significantly lower than Delphi at L1-L4 spine (1.0% vs 1.2%), total femur (0.9% vs 1.3%), femoral neck (1.5% vs 1.9%), and dual total femur (0.6% vs 0.9%). Dual femur modes decreased precision errors by approximately 25% compared with single femur results. CONCLUSIONS: This study suggests that short-term BMD precision errors are skeletal-site and manufacturer specific. In clinical practice, precision should be considered when determining: (a) the minimum time interval between baseline and follow-up scans and (b) whether a statistically significant change in the patient's BMD has occurred.

BACKGROUND: Steroid resistance and steroid dependence constitute a major problem in the treatment of minimal-change disease and focal segmental glomerulosclerosis (FSGS). Cyclophosphamide and cyclosporine are well-established alternative immunomodulating agents, whereas data on FK 506 (tacrolimus) are rare. METHODS: The present work provides data from 10 patients of an open, monocentric, non-randomized, prospective trial. Five patients with steroid-dependent minimal-change nephrotic syndrome, 1 patient with steroid-refractory minimal-change disease and 4 patients with steroid-refractory FSGS were started on tacrolimus at trough levels of 5 10 microg/l. In case of steroid-dependence, prednisolone was tapered off in presence oftacrolimus within one month. RESULTS: Within 6 months, complete remission was achieved in 5 patients (50%) and partial remission in 4 patients (40%), yielding a final response rate of 90%. One patient was primarily resistent to tacrolimus (steroid-refractory minimal-change), another patient became secondarily resistant to tacrolimus after an initial remission (steroid-refractory FSGS). Average proteinuria significantly decreased by 77% from 9.5 +/- 1.4 - 2.2 +/- 1.1 g/day (p \textless 0.01). Serum protein significantly raised from 55.0 +/- 1.9 - 64.6 +/- 1.9 g/l (p \textless 0.01). Tacrolimus induced non-significant increases of blood glucose (4.9 +/- 0.1 - 5.1 +/- 0.2 mmol/l), systolic blood pressure (131.4 +/- 7.1 - 139.0 +/- 7.6 mmHg) and creatinine (93.2 +/- 13.9 103.2 +/- 15.3 mmol/l). Five patients have been tapered off tacrolimus so far, nephrotic syndrome relapsed in 4 of them (80%). Relapse occurred at tacrolimus levels between 2.6 and 6.9 ng/ml. CONCLUSIONS: Our data suggest that tacrolimus may be a promising alternative to cyclosporine both in steroid-resistant and steroid-dependent nephrotic syndrome.

OBJECTIVE: The association between infertility and minimal to mild endometriosis is controversial and poorly understood. The clinical pregnancy rate (PR) per cycle after controlled ovarian hyperstimulation (COH) with or without intrauterine insemination (IUI) is reportedly lower in women with surgically untreated minimal to mild endometriosis than in women with unexplained infertility. It is possible that prior laparoscopic removal of endometriosis has a positive effect on the clinical PR after COH and IUI. Therefore, we tested the hypothesis that after COH and IUI the PR per cycle and the cumulative live-birth rate (CLBR) are equal or higher in women with recently surgically treated minimal to mild endometriosis when compared with women with unexplained infertility. DESIGN: A retrospective, controlled cohort study. SETTING: Leuven University Fertility Centre, a tertiary academic referral center. PATIENT(S): One hundred seven women treated during 259 cycles with COH and IUI including patients with endometriosis (n = 58, 137 cycles) and unexplained infertility (n = 49, 122 cycles). All patients with endometriosis had minimal (n = 41, 100 cycles) or mild (n = 17, 37 cycles) disease that had been laparoscopically removed within 7 months before the onset of treatment with COH and IUI. INTERVENTION(S): Controlled ovarian hyperstimulation using clomiphene citrate (23 cycles) or gonadotrophins (236 cycles) in combination with IUI. MAIN OUTCOME MEASURE(S): Clinical PR per cycle and CLBR within four cycles of treatment with COH and IUI. RESULT(S): The clinical PR per cycle was comparable in women with minimal or mild endometriosis (21% or 18.9%, respectively) and in women with unexplained infertility (20.5%). The CLBR within four cycles of COH and IUI was also comparable in women with minimal endometriosis, mild endometriosis, and unexplained infertility (70.2%, 68.2 %, 66.5%, respectively). CONCLUSION(S): The data from our study suggest that COH and IUI shortly after laparoscopic excision of endometriosis is as effective as COH and IUI in patients with unexplained subfertility.

BACKGROUND: The majority of medicines prescribed for children are prescribed in primary care for common acute and chronic conditions. This is in contrast to prescribing in secondary care where the population of children admitted is small but where a large number of different medicines are prescribed to treat more serious and less common conditions. METHODS: Data on prescribing was extracted from the General Practice Administration System for Scotland (GPASS) for the year November 1999 to October 2000 and prescribing patterns for children aged 0-16 years expressed as percentages. A comparison of age specific consultations for asthma, as an example of a common paediatric condition, was also made between two separate general practice data sets, the General Practice Research Database (GRPD) and the continuous morbidity recording (CMR) subset of GPASS. RESULTS: Of 214 medicines investigated for unlicensed and off-label prescribing no unlicensed prescribing was identified. Off-label prescribing due to age was most common among younger and older children. The most common reasons for off-label prescriptions were, in order of frequency, lower than recommended dose, higher than recommended dose, below the recommended age, and unlicensed formulation. Age and gender specific consultations for asthma were similar in the two representative databases, GPRD and CMR, both showing disappearance of the male predominance in the teenage years. CONCLUSIONS: Large primary care data sets available within a unified health care system such as the UK National Health Service (NHS) are likely to be broadly compatible and produce similar results. The prescribing of off-label medicines to children is common in primary care, most commonly due to prescribing out with the recommended dosage regimen.

Modelling the recent common ancestry of all living humans. Rohde, D., L., Olson, S., & Chang, J., T. Nature, 431(7008):562-566, 2004.
Paper abstract bibtex
Paper abstract bibtex If a common ancestor of all living humans is defined as an individual who is a genealogical ancestor of all present-day people, the most recent common ancestor (MRCA) for a randomly mating population would have lived in the very recent past. However, the random mating model ignores essential aspects of population substructure, such as the tendency of individuals to choose mates from the same social group, and the relative isolation of geographically separated groups. Here we show that recent common ancestors also emerge from two models incorporating substantial population substructure. One model, designed for simplicity and theoretical insight, yields explicit mathematical results through a probabilistic analysis. A more elaborate second model, designed to capture historical population dynamics in a more realistic way, is analysed computationally through Monte Carlo simulations. These analyses suggest that the genealogies of all living humans overlap in remarkable ways in the recent past. In particular, the MRCA of all present-day humans lived just a few thousand years ago in these models. Moreover, among all individuals living more than just a few thousand years earlier than the MRCA, each present-day human has exactly the same set of genealogical ancestors.

}Founder mutations among the Dutch. Zeegers, M., P., van Poppel, F., Vlietinck, R., Spruijt, L., & Ostrer, H. Eur J Hum Genet, 12(7):591-600, 2004.
Paper Website abstract bibtex
Paper Website abstract bibtex Many genetic disorders demonstrate mutations that can be traced to a founder, sometimes a person who can be identified. These founder mutations have generated considerable interest, because they facilitate studies of prevalence and penetrance and can be used to quantify the degree of homogeneity within a population. This paper reports on founder mutations among the Dutch and relates their occurrence to the history and demography of the Netherlands. International migration, regional and religious endogamy, and rapid population growth played key roles in shaping the Dutch population. In the first millenniums BC and AD, the Netherlands were invaded by Celts, Romans, Huns, and Germans. In more recent times, large numbers of Huguenots and Germans migrated into the Netherlands. Population growth within the Netherlands was slow until the 19th century, when a period of rapid population growth started. Today, the Dutch population numbers 16 million inhabitants. Several different classes of founder mutations have been identified among the Dutch. Some mutations occur among people who represent genetic isolates within this country. These include mutations for benign familial cholestasis, diabetes mellitus, type I, infantile neuronal ceroid lipofuscinosis, L-DOPA responsive dystonia, and triphalangeal thumb. Although not related to a specific isolate, other founder mutations were identified only within the Netherlands, including those predisposing for hereditary breast-ovarian cancer, familial hypercholesterolemia, frontotemporal dementia, hereditary paragangliomas, juvenile neuronal ceroid lipofuscinosis, malignant melanoma, protein C deficiency, and San Filippo disease. Many of these show a regional distribution, suggesting dissemination from a founder. Some mutations that occur among the Dutch are shared with other European populations and others have been transmitted by Dutch emigres to their descendents in North America and South Africa. The occurrence of short chromosomal regions that have remained identical by descent has resulted in relatively limited genetic heterogeneity for many genetic conditions among the Dutch. These observations demonstrate the opportunity for gene discovery for other diseases and traits in the Netherlands.

BACKGROUND: Systemic inflammation has been shown to be associated with an increased risk of acute myocardial infarction (AMI). However, the effect of the use of nonsteroidal anti-inflammatory drugs (NSAIDs) on the risk of AMI has not yet been well defined. We therefore studied the risk of AMI during NSAID exposure and after the cessation of NSAID therapy. METHODS: We conducted a large case-control analysis on the British General Practice Research Database. The study included 8688 cases with a first-time AMI between 1995 and 2001 and 33 923 controls, matched to cases on age, sex, calendar time, and general practice attended. RESULTS: After adjusting for hypertension, hyperlipidemia, diabetes mellitus, ischemic heart disease, rheumatoid arthritis, systemic lupus erythematosus, acute chest infection, body mass index, smoking, and aspirin use, the risk of AMI was 1.52 (95% confidence interval [CI], 1.33-1.74) for subjects who stopped taking NSAIDs 1 to 29 days prior to the index date, compared with nonusers. The risk was highest in subjects with rheumatoid arthritis or systemic lupus erythematosus (adjusted OR, 3.68 [95% CI, 2.36-5.74]) and for subjects who discontinued therapy with NSAIDs after previous long-term use (adjusted OR, 2.60 [95% CI, 1.84-3.68]). Current and past NSAID use (discontinued therapy \textgreater/=60 days prior to the index date) were not associated with an increased risk of AMI (adjusted OR, 1.07 [95% CI, 0.96-1.19] and 1.05 [95% CI, 0.99-1.12], respectively). CONCLUSION: Our findings suggest that the risk of AMI is increased during several weeks after the cessation of NSAID therapy.

OBJECTIVE: To increase the knowledge base on the frequency, causality, and avoidability of adverse drug events (ADEs) as a cause for admission in internal medicine or when occurring during hospitalization. METHODS: A prospective study was performed for 6 periods of 8 days each. Epidemiologic data (e.g., age, gender, medical history), drug utilization, and adverse drug reactions on patients hospitalized during these periods were collected by a pharmacy student. RESULTS: A total of 156 patients (70 men and 86 women) were included in the study. The patients' mean age +/- SD was 66.5 +/- 18.1 years and mean length of stay was 13.2 +/- 9 days. Renal and hepatic insufficiency and previous history of drug intolerance were observed in 17.9%, 10.2%, and 2% of the hospitalized patients, respectively. Thirty-eight ADEs occurred in 32 patients; in 15 cases, ADEs were identified as the reason for admission, 10 cases occurred during hospitalization, and 13 cases were present at admission, but were not the cause of admission. The most frequent ADEs involved the neurologic (23.6%), renal (15.7%), and hematologic (13.1%) systems. Among these 38 ADEs, 22 were considered avoidable (57.9%); 20 of these were associated with therapeutic errors (inappropriate administration, drug-drug interactions, dosage error, drug not stopped despite the onset of ADEs). Patients with ADEs stayed longer in the hospital and took more drugs both before and during their hospital stay (p \textless 0.05). CONCLUSIONS: Most of the ADEs observed in this study were avoidable. The risk/benefit ratio of administered drugs could be improved with better knowledge of the patients' medical history and the risk factors of ADEs.

METHODS: A prospective study was performed for 6 periods of 8 days each. Epidemiologic data (e.g., age, gender, medical history), drug utilization, and adverse drug reactions on patients hospitalized during these periods were collected by a pharmacy student.
RESULTS: A total of 156 patients (70 men and 86 women) were included in the study. The patients' mean age +/- SD was 66.5 +/- 18.1 years and mean length of stay was 13.2 +/- 9 days. Renal and hepatic insufficiency and previous history of drug intolerance were observed in 17.9\%, 10.2\%, and 2\% of the hospitalized patients, respectively. Thirty-eight ADEs occurred in 32 patients; in 15 cases, ADEs were identified as the reason for admission, 10 cases occurred during hospitalization, and 13 cases were present at admission, but were not the cause of admission. The most frequent ADEs involved the neurologic (23.6\%), renal (15.7\%), and hematologic (13.1\%) systems.

OBJECTIVES: To review the recent literature on possible causes of the increase in frequency of diagnosed autism reported from three countries, and to compare the medical diagnoses and drug therapy from a new series of autistic boys and their mothers with that of comparable nonautistic boys and their mothers. DESIGN: Case-control evaluation. PARTICIPANTS: Members of over 250 general practices in the United Kingdom. MEASUREMENTS AND MAIN RESULTS: Frequency of exposure to drugs and presence of preexisting clinical illnesses in autistic children and their mothers were compared with nonautistic children and their mothers over time. According to published studies, the incidence of boys diagnosed with autism rose dramatically in the 1990s. Numerous published studies have concluded that the measles-mumps-rubella vaccine is not responsible for the large rise in diagnosed autism. In our study, boys diagnosed with autism had medical and drug histories, such as vaccines, before diagnosis, that were closely similar to those of nonautistic boys, except that developmental and sensory disorders were far more common in autistic boys. No material differences during pregnancy were found between the mothers of autistic boys and those of nonautistic boys in relation to illness or drug therapy. In the early 1990s, boys with diagnosed developmental disorders were infrequently diagnosed with autism. In the later 1990s, such boys more often were diagnosed with autism. CONCLUSION: A major cause of the recent large increase in the number of boys diagnosed with autism probably is due to changing diagnostic practices.

AIMS: Aspirin decreases the risk of clinical manifestations of atherothrombosis. This effect is mainly due to inhibition of platelet aggregation and potentially due to anti-inflammatory properties of aspirin. To evaluate whether use of non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) may also be associated with a decreased risk of first-time acute myocardial infarction (AMI), we performed a population-based case-control analysis using the United Kingdom-based General Practice Research Database (GPRD) METHODS: We identified first-time AMI-patients free of preexisting diagnosed cardiovascular or metabolic diseases. We compared use of NSAIDs prior to the index date between cases and control patients who were matched to cases on age, gender, practice and calendar time. RESULTS: A total of 3319 cases (\textlessor=75 years) with a diagnosis of first-time AMI between 1992 and 1997 and 13139 controls (matched to cases on age, sex, general practice attended, calendar time, years of prior history in the GPRD) were included. Overall, the relative risk estimate of AMI (adjusted for smoking, body mass index, hormone replacement therapy and aspirin) in current NSAID users was 1.17 (95% CI 0.99, 1.37). Long-term current NSAID use (\textgreateror=30 prescriptions) yielded an adjusted odds ratio (OR) of 1.20 (95% CI 0.94, 1.55). Stratification by age (\textless65 years vs\textgreateror=65 years) and sex did not materially change the results. CONCLUSIONS: Our findings indicate that current NSAID exposure in patients free of diagnosed cardiovascular or metabolic conditions predisposing to cardiovascular diseases does not decrease the risk of AMI.

Paper Website abstract bibtex Dementia affects about 5% of the elderly population over age 65 years and has an unexplained predominance in women and a low rate in some cultures. Different forms of dementia are now distinguished-Alzheimer's disease, dementia with Lewy bodies, frontotemporal dementia, and dementia secondary to disease, such as AIDS dementia. However, such nosological boundaries are being re-evaluated because different dementias are believed to have common underlying neuropathology. Neurochemical and neurobiological research has led to advances in understanding causes of dementia, and functional imaging has allowed identification of possible biomarkers; from these, a range of potential treatment approaches have arisen that focus on enhancement of neurotransmitter function, intervention at the level of amyloid production and deposition, and reduction of secondary risk factors such as hypertension, depression, and hypolipidaemia. Molecular diagnostic testing and genetic counselling for families with autosomal dominant early-onset dementia are new developments; however, this approach is not useful for late-onset dementia, in which the identified candidate susceptibility genes have a relatively small effect on risk. While fundamental research works towards new biological treatment strategies, much remains to be done in the area of disease management and the development of appropriate models of long-term care.

Website abstract bibtex
Website abstract bibtex The present paper grounds the linguistic cdategorization of space in aspects of visual perception; specifically, the structure of projective spatial terms such as above are grounded in the process of attention and in vector-sum coding of overall direction. This is formalized in the attentional vector-sum (AVS) model. This computational model accurately predicts linguistic acceptability judgments for spatial terms, under a variety of spatial configurations. In 7 experiments, the predictions of the AVS model are tested against those of 3 competing models. The results support the AVS model and disconfirm its competitors. The authors conclude that the structure of linguistic spatial categories can be partially explained in terms of independently motivated perceptual processes.

abstract bibtex
abstract bibtex
Nonsteroidal anti-inflammatory drugs (NSAIDs) have been associated with an increase in upper gastrointestinal complications. There is no agreement, however, on whether all conventional NSAIDs have a similar relative risk (RR), and epidemiologic data are limited on acetaminophen. We studied the association between these medications and the risk of upper gastrointestinal bleed/perforation in a population-based cohort of 958,397 persons in the United Kingdom between 1993 and 1998. Our nested case-control analysis included 2,105 cases and 11,500 controls. RR estimates were adjusted for several factors known to be associated with upper gastrointestinal bleed/perforation. Compared with non-users, users of acetaminophen at doses less than 2 gm did not have an increased risk of upper gastrointestinal complications. The adjusted RR for acetaminophen at doses greater than 2 gm was 3.6 [95% confidence interval (95% CI) = 2.6-5.1]. The corresponding RRs for low/medium and high doses of NSAIDs were 2.4 (95% CI = 1.9-3.1) and 4.9 (95% CI = 4.1-5.8). The RR was 3.1 (95% CI = 2.5, 3.8) for short plasma half-life, 4.5 (95% CI = 3.5-5.9) for long half-life, and 5.4 (95% CI = 4.0-7.1) for slow-release formulations of NSAIDs. After adjusting for daily dose, the differences in RR between individual NSAIDs tended to diminish except for apazone. Users of H2 receptor antagonists, omeprazole, and misoprostol had RRs of 1.4 (95% CI = 1.2-1.8), 0.6 (95% CI = 0.4-0.9), and 0.6 (95% CI = 0.4-1.0), respectively. Among NSAID users, use of nitrates was associated with an RR of 0.6 (95% CI = 0.4-1.0).

Oral corticosteroids and fracture risk: relationship to daily and cumulative doses. van Staa, T. P., Leufkens, H. G., Abenhaim, L., Zhang, B., & Cooper, C. Rheumatology (Oxford, England), 39(12):1383--1389, December, 2000.

OBJECTIVE: This study examined the effects of daily and cumulative oral corticosteroid doses on the risk of fractures. METHODS: Information was obtained from the General Practice Research Database, which contains medical records of general practitioners in England and Wales. The study included 244 235 oral corticosteroid users and 244 235 controls. RESULTS: Patients taking higher doses (at least 7. 5 mg daily of prednisolone or equivalent) had significantly increased risks of non-vertebral fracture [relative rate (RR)=1.44, 95% confidence interval (CI) 1.34-1.54], hip fracture (RR=2.21, 95% CI 1.85-2.64) and vertebral fracture (RR=2.83, 95% CI 2.35-2.40) relative to patients using oral corticosteroids at lower doses (less than 2.5 mg per day). Fracture risk was also elevated among people with higher cumulative exposure to oral corticosteroids over the study period, but this effect was almost wholly removed by adjustment for daily dose, age, gender and other confounding variables. CONCLUSIONS: These findings suggest that the adverse skeletal effects of oral corticosteroids manifest rapidly and are related to daily dose. The level of previous exposure to oral corticosteroids was not a strong determinant of the risk of fracture. Preventive measures against corticosteroid-induced osteoporosis should therefore be instituted as soon after the commencement of glucocorticoid therapy as possible.

Website abstract bibtex
Website abstract bibtex Multivariate survival models are shown to be appropriate for the analysis of the genetic and the environmental nature of a human life-span. Models which involve continuously distributed individual frailty, play an important role in the genetic analysis of an individual's susceptibility to disease and death. These models, however, are not appropriate for the detection of the effects of separate genes on survival. For this purpose we developed a 'major gene' frailty model of multivariate survival and applied it to simulated and real pedigree data. The analysis shows that this model can be used for the detection of the presence of major genes in the population and for the evaluation of the effects of such genes on survival.

abstract = {Multivariate survival models are shown to be appropriate for the analysis of the genetic and the environmental nature of a human life-span. Models which involve continuously distributed individual frailty, play an important role in the genetic analysis of an individual's susceptibility to disease and death. These models, however, are not appropriate for the detection of the effects of separate genes on survival. For this purpose we developed a 'major gene' frailty model of multivariate survival and applied it to simulated and real pedigree data. The analysis shows that this model can be used for the detection of the presence of major genes in the population and for the evaluation of the effects of such genes on survival.},

}Risk of venous thromboembolism among users of third generation oral contraceptives compared with users of oral contraceptives with levonorgestrel before and after 1995: cohort and case-control analysis. Jick, H., Kaye, J. A., Vasilakis-Scaramozza, C., & Jick, S. S. BMJ (Clinical research ed.), 321(7270):1190--1195, November, 2000.

OBJECTIVE: To compare the risk of idiopathic venous thromboembolism among women taking third generation oral contraceptives (with gestodene or desogestrel) with that among women taking oral contraceptives with levonorgestrel. DESIGN: Cohort and case-control analyses derived from the General Practice Research Database. SETTING: UK general practices, January 1993 to December 1999. PARTICIPANTS: Women aged 15-39 taking third generation oral contraceptives or oral contraceptives with levonorgestrel. MAIN OUTCOME MEASURES: Relative incidence (cohort study) and odds ratios (case-control study) as measures of the relative risk of venous thromboembolism. RESULTS: The adjusted estimates of relative risk for venous thromboembolism associated with third generation oral contraceptives compared with oral contraceptives with levonorgestrel was 1.9 (95% confidence interval 1.3 to 2.8) in the cohort analysis and 2.3 (1.3 to 3.9) in the case-control study. The estimates for the two types of oral contraceptives were similar before and after the warning issued by the Committee on Safety of Medicines in October 1995. A shift away from the use of third generation oral contraceptives after the scare was more pronounced among younger women (who have a lower risk of venous thromboembolism) than among older women. Fewer cases of venous thromboembolism occurred in 1996 and later than would have been expected if the use of oral contraceptives had remained unchanged. CONCLUSIONS: These findings are consistent with previously reported studies, which found that compared with oral contraceptives with levonorgestrel, third generation oral contraceptives are associated with around twice the risk of venous thromboembolism.

Unique PABP2 mutations in "Cajuns" suggest multiple founders of oculopharyngeal muscular dystrophy in populations with French ancestry. Scacheri, P., C., Garcia, C., Hébert, R., Hoffman, E., P., & Hebert, R. Am J Med Genet, 86(5):477-481, 10, 1999.

Paper Website abstract bibtex Oculopharyngeal muscular dystrophy (OPMD) is an adult-onset autosomal dominant myopathy found world-wide, but with the highest incidence in French-Canadians. Short GCG expansions in the poly(A) binding protein 2 (PABP2) gene were identified recently as the molecular basis for OPMD in French-Canadians. All French-Canadian cases of OPMD have been traced to a single founder couple [Bouchard, 1997: Neuromuscul Disord 7(Suppl):S5-S11]. Cultural links between French-Canadians and Cajuns suggest that this same founder couple may have transmitted the OPMD mutation to Cajuns as well. To determine if OPMD patients from Louisiana share a founder effect with French-Canadian families, we collected blood samples and muscle biopsies from several Cajuns with OPMD for mutation and linkage studies. We found a unique 'GCA GCG GCG' insertion mutation in Cajuns. Consistent with these sequence data, we identified a disease haplotype in our Cajun families that is different from the ancestral haplotype defined in French-Canadians. These data prove that different founders introduced the PABP2 mutation to Cajuns and French-Canadians and lend support to emerging genealogical data suggesting that French-Canadians and Cajuns represent distinct immigrant groups from France.

This study investigated the visual-proprioceptive mapping ability of children with DCD from a small selected group, with particular reference to the use of vision in matching tasks. The children with DCD in this study were significantly poorer than control children on all matching tasks. They seemed to have particular difficulty in cross-modal judgements that required the use of visual information to guide proprioceptive judgements of limb position. A distinction is drawn between tasks that can be achieved purely through sensory matching and those that require body-centred spatial judgements, suggesting that it is the latter that posits a particular difficulty for children with DCD

BACKGROUND: Studies of couples, who tend to share an environment but are genetically dissimilar, can shed light on the contribution of environmental factors to hypertension. There has been renewed interest in these environmental factors following the re-analysis of the INTERSALT study. AIM: To determine whether patients whose spouses have hypertension are at increased risk of hypertension, using a population-based case-control study. METHOD: The total study population consisted of all 3923 patients over 30 years old registered with one general practice. Male cases with hypertension were matched to male controls without hypertension. Female cases with hypertension were matched to female controls without hypertension. The variables were: diagnosed hypertension; having a spouse with diagnosed hypertension; age; sex; weight; height; body-mass index; couple status; diabetes; and systolic and diastolic blood pressure readings. RESULTS: On multivariate analysis, when age, body-mass index, diabetes, couple status, and having a blood pressure reading were included, men whose spouses had hypertension had a two-fold increased risk of hypertension (adjusted odds ratio (OR) 2.24; 95% CI 1.77-2.72; P = 0.001). Similarly, on multivariate analysis, women whose spouses had hypertension had a two-fold increased risk of hypertension (adjusted OR = 2.23; 95% CI 1.75-2.72; P = 0.001). The risk for both male and female subjects persisted after adjustment for other variables. There was a significant correlation between systolic (r = 0.41; P \textless 0.0001) and diastolic (r = 0.25; P \textless 0.0001) blood pressures between spouse pairs. CONCLUSION: The independent association between having a spouse with hypertension and increased risk of hypertension supports the view that there are significant environmental factors in the aetiology of hypertension. The finding has implications for the screening and treatment of hypertension in primary care.

A group of 7977 patients taking cyclic etidronate and two age-, gender-, and practice-matched control groups, one with osteoporosis and one without, were analyzed. For the group taking cyclic etidronate, the average age was 71.6 years and follow-up was 10,328 person-years. Conditions that do not induce osteoporosis generally occurred in these patients at a rate comparable to that in the control groups. The incidence of osteomalacia was low and comparable between patients taking cyclic etidronate and controls with osteoporosis. No medically significant increases in frequency were observed among patients taking cyclic etidronate for a broad group of diseases that may potentially be induced by exposure to the drug. These data support the favorable risk:benefit ratio of cyclic etidronate.

abstract bibtex
Birth statistics over a period of 5 years were analyzed to study epidemiological characteristics of twinning in Southeast Uttar Pradesh, India. The data revealed higher incidence of breech twins (11.84% of all cotwins) as compared to breech single births (2.18%). But the perinatal mortality and caesarean section rates were similar in both twin and singleton pregnancies. The cumulative twinning rate over the studied period was 11.70 per 1000 live births. The MZ and DZ twinning rates were estimated respectively as 3.67 and 8.03 per mill. The mean maternal age of sampled mothers was 26.42 years with one standard deviation of 5.30 years. The twinning rate for mothers over 35 years of age was about four times higher than that in mothers younger than 20 years. Incidentally, the twinning rate was the highest at parity four and a non-linear curve could more appropriately be fitted to the series of data. Seasonal variations were observed for both twin and singleton births. The highest frequency of births was observed from August through October. But seasonal index for twinning rate showed a clear bimodal distribution with peaks in April (223) and September (167).

Website abstract bibtex
Website abstract bibtex Although asthma has a significant heritable component, the mode of inheritance remains controversial because of the complexity of the disease and the influence of environmental factors. Isolated, inbred populations serve to reduce variability, thus increasing the probability of gene localization. We studied the inbred population of the remote island of Tristan da Cunha to document asthma prevalence for the purpose of genetic linkage analysis. Medical histories and skin atopy were determined on 282 islanders, representing 97% of the population, and airway responsiveness was measured in 254; 226 by methacholine challenge (tidal breathing method) and 28 by bronchodilator response (400 micrograms salbutamol aerosol). Blood samples were collected from 275 islanders. Participants ranged in age from 3 to 94 yr. Asthma was defined as increased airway responsiveness (AR+: PC20 < 4 mg/ml or > or = 15% increase in FEV1 postbronchodilator) combined with a positive history (Hx+). Fifty-seven percent of the islanders had at least partial evidence of asthma (Hx+ and/or AR+) and 23% had a definitive diagnosis of asthma (AR+ with Hx+). Overall 47% of the population were atopic, atopy was proportionally higher in asthmatics (74%) than nonasthmatics (32%; p < 0.01). Analysis of the methacholine dose-response curves demonstrated that asthmatics were significantly (p < 0.01) more responsive than those with AR+ only, and nonasthmatics (AR-, Hx-) were more responsive than laboratory control subjects (p < 0.05), suggesting that these islanders may also carry an airway hyperresponsiveness gene. A frequency plot of the percent fall in FEV1 for all Hx- subjects compared with control data suggests a bimodal distribution consistent with a major gene mechanism for airway responsiveness. Genealogy mapping revealed that the islanders are direct descendants of the 15 original settlers, and historical records suggest at least two founders may have been asthmatic. The data confirm previous reports of a high asthma prevalence on Tristan and support the postulate that this prevalence is a result of gene enrichment occurring in isolated populations by virtue of extensive inbreeding and a probable founder effect.

Serum ionized calcium concentration in clinically normal dairy cattle, and changes associated with calcium abnormalities. Lincoln, S D & Lane, V M Journal of the American Veterinary Medical Association, 197(11):1471--4, December, 1990.
Paper abstract bibtex
Paper abstract bibtex Serum ionized calcium (ICa) concentration was determined in 141 clinically normal dairy cattle by use of a direct-measuring calcium ion-selective electrode instrument. Mean serum ICa concentration 2 hours after blood withdrawal was 4.59 mg/dl; range varied from 3.79 to 5.25 mg/dl. Regression analysis indicated a high degree of correlation between ICa and serum total calcium concentrations if serum stored at 23 C was analyzed within 12 hours after blood withdrawal. Abnormal ICa concentration was detected in 19 of 85 dairy cows that were affected with various pathologic conditions. All 19 cows had hypocalcemia (n = 13 with parturient hypocalcemia, 4 with hypomagnesemic tetany, and 2 with renal disease). In all cases, the ICa concentration clearly related to the clinical manifestation of disease and the functional status of the cow's calcium metabolism.

Frequency and intensity discrimination in humans and monkeys. Sinnott, J., Petersen, M., & Hopp, S. 78(6):1977-1985, 1985.
abstract bibtex
abstract bibtex
Frequency and intensity DLs were compared in humans and monkeys using a repeating standard "yes-no" procedure in which subjects reported frequency increments, frequency decrements, intensity increments, or intensity decrements in an ongoing train of 1.0-kHz tone bursts. There was only one experimental condition (intensity increments) in which monkey DLs (1.5-2.0 dB) overlapped those of humans (1.0-1.8 dB). For discrimination of both increments and decrements in frequency, monkey DLs (16-33 Hz) were approximately seven times larger than those of humans (2.4-4.8 Hz), and for discrimination of intensity decrements, monkey DLs (4.4-7.0 dB) were very unstable and larger than those of humans (1.0-1.8 dB). For intensity increment discrimination, humans and monkeys also exhibited similar DLs as SL was varied. However, for frequency increment discrimination, best DLs for humans occurred at a high (50 dB) SL, whereas best DLs for monkeys occurred at a moderate (30 dB) SL. Results are discussed in terms of various neural mechanisms that might be differentially engaged by humans and monkeys in performing these tasks; for example, different amounts of temporal versus rate coding in frequency discrimination, and different mechanisms for monitoring rate decreases in intensity discrimination. The implications of these data for using monkeys as models of human speech sound discrimination are also discussed.

Sex differences in the association between body mass index and total hip or knee joint replacement resulting from osteoarthritis. Franklin, J., Ingvarsson, T., Englund, M., & Lohmander, L. S. 68(4):536--540.
doi abstract bibtex
doi abstract bibtex
OBJECTIVE: To examine the association between body mass index (BMI) and osteoarthritis (OA) leading to total hip (THR) or knee (TKR) joint replacement. METHODS: Case-control study design. All patients still living in Iceland who had had a THR or TKR resulting from OA before the end of 2002 were invited to participate. First-degree relatives of participating patients served as controls. A total of 1473 patients (872 women) and 1103 controls (599 women), all born between 1910 and 1939 and who had answered a questionnaire including questions about height and weight, were analysed. A randomly selected sample, representative of the Icelandic population, was used as a secondary control group. RESULTS: The OR, adjusted for age, occupation and presence of hand OA, for having a THR was 1.1 (95% CI 0.9 to 1.5) for overweight men and 1.7 (95% CI 1.0 to 2.9) for obese men. The OR for having a TKR was 1.7 (95% CI 1.1 to 2.6) for overweight men and 5.3 (95% CI 2.8 to 10.1) for obese men. The OR for having a THR was 1.0 (95% CI 0.8 to 1.3) for overweight women and 1.0 (95% CI 0.6 to 1.5) for obese women. The OR for having a TKR was 1.6 (95% CI 1.1 to 2.2) for overweight women and 4.0 (95% CI 2.6 to 6.1) for obese women. CONCLUSION: This study supports a positive association between high BMI and TKR in both sexes, but for THR the association with BMI seems to be weaker, and possibly negligible for women.
