Fifty patients completed the study, with 25 patients receiving 4/0.5 g piperacillin/tazobactam over 30 min as the II group and 25 patients receiving 4/0.5 g piperacillin/tazobactam over 3 h every 6 h as the EI group. Drug assay was performed using high-performance liquid chromatography (HPLC). The percentage of the dosing interval for which the free piperacillin concentration (\%fT) exceeds the minimum inhibitory concentration (MIC) was calculated. The patients' therapy cost, clinical efficiency, and adverse effects were also recorded. \%fT{\textgreater}MIC was about 100, 98.73, and 93.04 \% in the EI arm versus 81.48, 53.29, and 42.15 \% in the II arm, respectively, when the microorganism responsible for HAP had an MIC of 4, 8, and 16 mg/L. The therapy cost in the EI group was lower than that of the II group (\$1351.72+/-120.39 vs. \$1782.04+/-164.51, p=0.001). However, the clinical success rate, clinical failure rate, and drug-related adverse events did not significantly differ between groups.

The aim of this study is to investigate the impact of the time interval between port placement and initiation of chemotherapy and the neutropenia-inducing potential of the chemotherapy administered upon complication-related port removal. PATIENTS AND METHODS: Between January 2010 and December 2013, 4045 consecutive patients were included in this observational, single-center prospective study. The chemotherapy regimens were classified as having a low ({\textbackslash}textbackslashtextless10\%), intermediate (10-20\%), or high ({\textbackslash}textbackslashtextgreater20\%) risk for inducing neutropenia. RESULTS: The overall removal rate due to complications was 7.2\%. Among them, port-related infection (2.5\%) and port expulsion (1\%) were the most frequent. The interval between port insertion and its first use was shown to be a predictive factor for complication-related removal rates. A cut-off of 6 days was statistically significant (p = 0.008), as the removal rate for complications was 9.4\% when this interval was 0-5 days and 5.7\% when it was {\textbackslash}textbackslashtextgreater/=6 days. Another factor associated with port complication rate was the neutropenia-inducing potential of the chemotherapy regimens used, with removal for complications involved in 5.5\% of low-risk regimens versus 9.4\% for the intermediate- and high-risk regimens (p = 0.003). CONCLUSION: An interval of 6 days between placement and first use of the port reduces the removal rate from complications. The intermediate- and high-risk for neutropenia chemotherapy regimens are related to higher port removal rates from complications than low-risk regimens.}, number = {4}, journal = {Eur J Surg Oncol}, author = {Kakkos, A. and Bresson, L. and Hudry, D. and Cousin, S. and Lervat, C. and Bogart, E. and Meurant, J.

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.

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.}, language = {eng}, journal = {Obesity Research \& Clinical Practice}, author = {Kiadaliri, Aliasghar A. and Asadi-Lari, Mohsen and Kalantari, Naser and Jafari, Mehdi and Vaez Mahdavi, Mohammad Reza and Faghihzadeh, Soghrat}, month = sep, year = {2016}, pmid = {26003304}, keywords = {Adolescent, Adult, Aged, Aged, 80 and over, Educational Status, Educational inequality, Female, Generalized linear model, Humans, Iran, Male, Middle Aged, Obesity, Sex Factors, Social Class, Socioeconomic Factors, Urban-HEART, Young Adult}, pages = {S57--S63}, }

MATERIAL AND METHODS: Prospective study conducted at 21 Spanish hospitals including patients with MRSA bacteraemia diagnosed between June/2008 and December/2009. Episodes diagnosed in patients aged 75 or more years old (≥75) were compared with the rest of them ({\textless}75). RESULTS: Out of 579 episodes of MRSA bacteraemia, 231 (39.9\%) occurred in patients ≥75. Comorbidity was significantly higher in older patients (Charlson score ≥4: 52.8 vs. 44\%; p = .037) as was the severity of the underlying disease (McCabe ≥1: 61.9 vs. 43.4\%; p {\textless} .001).

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.

Aims of the present study are to describe the quality indicators of nutritional care in older residents in a sample of NHs in Tuscany, Italy, and to evaluate the predictors of protein-energy malnutrition risk. METHODS: A cross-sectional survey was conducted in 67 NHs. Information was collected to evaluate quality indicators of nutritional care and the individual risk factors for malnutrition, which was assessed using the Malnutrition Universal Screening Tool. A multilevel model was used to analyse the association between risk and predictors. RESULTS: Out of 2395 participants, 23.7 % were at high, 11 % at medium, and 65.3 % at low risk for malnutrition. Forty-two percent of the NHs had only a personal scale to weigh residents; 88 % did not routinely use a screening test/tool for malnutrition; 60 % used some standardized approach for weight measurement; 43 % did not assess the severity of dysphagia; 12 % were not staffed with dietitians. Patients living in NHs where a chair or platform scale was available had a significantly lower risk of malnutrition (OR = 0.73; 95 % CI = 0.56-0.94). None of the other structural or process quality indicators showed a statistically significant association with malnutrition risk. CONCLUSIONS: Of all the process and structural indicators considered, only the absence of an adequate scale to weigh residents predicted the risk of malnutrition, after adjusting for case mix. These findings prompt the conduction of further investigations on the effectiveness of structural and process indicators that are used to describe quality of nutritional care in NHs.}, bibtype = {article}, author = {Bonaccorsi, G and Collini, F and Castagnoli, M and Di Bari, M and Cavallini, M C and Zaffarana, N and Pepe, P and Mugelli, A and Lucenteforte, E and Vannacci, A and Lorini, C}, journal = {BMC health services research} }

However, in many cases, it would be more practical for interventions to be delivered after wounding. This preliminary study investigated whether a brief relaxation intervention could improve healing when administered either before or after skin damage produced by tape stripping in comparison to a control group. METHODS: One hundred twenty-one healthy adults were randomized into one of three groups: (a) relaxation prestripping group, (b) relaxation poststripping group, or (c) no relaxation. Participants completed measures of stress, fatigue, relaxation, and pain. Relaxation consisted of listening to 20 minutes of guided relaxation, whereas the control condition was quiet reading for 20 minutes. Skin barrier function was measured using transepidermal water loss at baseline, immediately after tape stripping and 25 minutes later. RESULTS: Relaxation either before or after tape stripping improved skin barrier recovery compared with the control group (F(2,92) = 3.58, p = .032, partial η = 0.074). Participants who took part in the relaxation intervention were significantly more relaxed and reported greater reductions in pain than the control group did 25 minutes after tape stripping. Perceived stress over the last month was not significantly related to healing. CONCLUSIONS: This study showed that a relaxation intervention had a beneficial effect on skin barrier recovery regardless of whether the intervention was administered before or after wounding.

Fourteen studies were eligible for inclusion. Overall, the literature on the co-occurrence of malnutrition and dysphagia in LTC shows a paucity of high-quality evidence. Articles reviewed lacked consistent definitions for both conditions. Methods used to confirm each diagnosis also differed and were of questionable validity. Based on a review of the literature, evidence of the existence of concurrent concerns with respect to malnutrition and dysphagia emerges. The reported frequency of participants in LTC with dysphagia ranges from 7% to 40%, while the percentage of those who were malnourished ranges from 12% to 54%. Due to discrepancies used to describe and measure these conditions, it is difficult to determine the exact prevalence of either condition separately, or in combination.

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.

METHOD: Case note reviews and interviews with residents, care home staff, and healthcare professionals. RESULTS: Twenty-three out of 121 recruited residents died during the study period. Four trajectories to death were identified: 'anticipated dying' with an identifiable end-of-life care period and death in the care home (n = 9); 'unexpected dying' with death in the care home that was not anticipated and often sudden (n = 3); 'uncertain dying' with a period of diagnostic uncertainty or difficult symptom management leading to hospital admission and inpatient death (n = 7); and 'unpredictable dying' with an unexpected event leading to hospital admission and inpatient death (n = 4).

METHODS. STUDY DESIGN: observational case series. Data on fatal carbon monoxide poisoning in England and Wales from 1979 to 2012 were obtained from coroner reports. Data on unintentional non-fire-related carbon monoxide poisoning were extracted and were analysed by year of registration of death, sex, age group, and whether death occurred at a private house, flat, associated garage, or residential caravan ('home'), or elsewhere. RESULTS AND DISCUSSION: There were 28,944 carbon monoxide-related deaths, of which 82\% were male. Deaths increased from 965 (1979) to 1700 (1987), and then fell to 182 (2012). Of these 2208 (64\% male) were recorded as unintentional non-fire-related deaths. Annual numbers of these latter deaths fell from 166 in 1979 to 25 in 2012 (i.e. from 3.37 to 0.44 per million population). Some 81 and 92\% of such deaths in males and in females, respectively, occurred at 'home'. A clear preponderance of male versus female deaths was seen in the 10-19, 20-39 and 40-64 years age groups, with similar numbers of deaths in males and in females in the younger ({\textless} 1 and 1-9 year) and higher (65-79 and 80 + years) age groups. A higher proportion of these excess deaths in males occurred outside the deceased's 'home' in those aged 10-19, 20-39 and 40-64 years. CONCLUSION: Deaths from unintentional non-fire-related carbon monoxide poisoning are now much less common in England and Wales than in earlier years, but remain a cause for concern.

We evaluated the risks of acute myocardial infarction (AMI) and death in patients initiating Olm compared with an active comparator group, other angiotensin receptor blockers (ARBs), with a focus on high-dose and diabetic subgroups. METHODS: We conducted a cohort study with patients who initiated Olm or another ARB between 2003 and 2011, using the UK Clinical Practice Research Datalink GOLD. We included patients who had no prior ARB or angiotensin converting enzyme inhibitor exposure during the preceding 6 months. Hazard ratios (HRs) were estimated using Cox regression models with both multivariable adjustment and propensity score matching. RESULTS: There were 3964 Olm and 54 653 other-ARB initiators, respectively.

Comparing patients initiated with a high-dose Olm and a high-dose other-ARB, HRs were 3.09 (0.94-10.13) for AMI and 2.03 (0.74-5.61) for death, using multivariable adjustment; and 4.38 (0.97-19.66) and 1.99 (0.63-6.32) for AMI and death, using propensity score matching. CONCLUSIONS: Overall, no differences in risk were observed in the main cohort analyses comparing Olm initiators with patients initiating therapy with other ARBs; however, HRs were marginally increased for all study endpoints which compared high-dose subgroups, suggesting potential increased risk may be associated with high-dose Olm.

As revealed by many cases worldwide, such a marketing strategy led to unintentional self-poisonings and deaths. FIPs therefore constitute a very serious health and public policy issue. To understand why FIPs are a threat, we first conducted a qualitative analysis on real-life cases of household cleaners and personal care products-related phone calls at a poison control center followed by a behavioral experiment. Unintentional self-poisoning in the home following the accidental ingestion of a hygiene product by a healthy adult is very likely to result from these products being packaged like foodstuffs. Our hypothesis is that FIPs are non-verbal food metaphors that could fool the brain of consumers. We therefore conducted a subsequent functional neuroimaging (fMRI) experiment that revealed how visual processing of FIPs leads to cortical taste inferences. Considered in the grounded cognition perspective, the results of our studies reveal that healthy adults can unintentionally categorize a personal care product as something edible when a food-like package is employed to market nonedible and/or dangerous products. Our methodology combining field (qualitative) and laboratory (behavioral and functional neuroimaging) findings could be of particular relevance for policy makers, as it can help screening products prior to their market release--e.g. the way they are packaged and how they can potentially confuse the mind of consumers--and therefore save lives.}, language = {eng}, number = {9}, journal = {PloS One}, author = {Basso, Frédéric and Robert-Demontrond, Philippe and Hayek, Maryvonne and Anton, Jean-Luc and Nazarian, Bruno and Roth, Muriel and Oullier, Olivier}, year = {2014}, pmid = {25207971}, pmcid = {PMC4160172}, keywords = {Adult, Aged, Aged, 80 and over, Behavior, Brain, Cosmetics, Drinking, Female, Food, Functional Neuroimaging, Hair Preparations, Humans, Magnetic Resonance Imaging, Male, Marketing, Middle Aged, Poison Control Centers, Public Health, Safety, Young Adult}, pages = {e100368} }

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).

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.

The current literature shows conflicting results in this regard. We applied the intravoxel incoherent motion model, which allows for the differentiation between diffusion (D) and perfusion (f) effects, to further elucidate potential underlying causes for these divergent reports. MATERIALS AND METHODS: Eighteen patients with primary rectal carcinoma undergoing preoperative CRT were examined before, during, and after neoadjuvant CRT using diffusion-weighted imaging. Using the intravoxel incoherent motion approach, f and D were extracted and compared with postoperative tumor downstaging and volume. RESULTS: Initial diffusion-derived parameters were within a narrow range (D1 = 0.94 ± 0.12 × 10(-3) mm(2)/s). At follow-up, D rose significantly (D2 = 1.18 ± 0.13 × 10(-3) mm(2)/s; P {\textless} 0.0001) and continued to increase significantly after CRT (D3 = 1.24 ± 0.14 × 10(-3) mm(2)/s; P {\textless} 0.0001). The perfusion fraction f did not change significantly (f1 = 9.4 ± 2.0\%, f2 = 9.4 ± 1.7\%, f3 = 9.5 ± 2.7\%). Mean volume (V) decreased significantly (V1 = 16,992 ± 13,083 mm(3); V2 = 12,793 ± 8317 mm(3), V3 = 9718 ± 6154 mm(3)). T-downstaging (10:18 patients) showed no significant correlation with diffusion-derived parameters.

However, the testosterone suppression associated with this therapy may lead to a hypogonadal condition that can have detrimental effects on renal function, thus raising the hypothesis that ADT-induced hypogonadism could potentially lead to acute kidney injury (AKI). OBJECTIVE: To determine whether the use of ADT is associated with an increased risk of AKI in patients newly diagnosed with prostate cancer. DESIGN AND SETTING: A nested case-control analysis using medical information extracted from the UK Clinical Practice Research Datalink linked to the Hospital Episodes Statistics database. PARTICIPANTS: Men newly diagnosed with nonmetastatic prostate cancer between January 1, 1997, and December 31, 2008, were selected and followed up until December 31, 2009. Cases were patients with incident AKI during follow-up who were randomly matched with up to 20 controls on age, calendar year of prostate cancer diagnosis, and duration of follow-up. MAIN OUTCOMES AND MEASURES: Conditional logistic regression was used to estimate odds ratios (ORs) with 95\% CIs of AKI associated with the use of ADT. ADT was categorized into 1 of 6 mutually exclusive groups: gonadotropin-releasing hormone agonists, oral antiandrogens, combined androgen blockade, bilateral orchiectomy, estrogens, and combination of the above. RESULTS A total of 10,250 patients met the study inclusion criteria. During a mean follow-up of 4.1 (SD, 2.9) years, 232 incident cases of AKI were identified (rate, 5.5/1000 person-years). Overall, current use of any ADT was associated with an increased risk of AKI when compared with never use (OR, 2.48 [95\% CI, 1.61-3.82]), generating a rate difference of 4.43/1000 persons per year (95\% CI, 1.54-7.33). This association was mainly driven by a combined androgen blockade consisting of gonadotropin-releasing hormone agonists with oral antiandrogens (OR, 4.50 [95\% CI, 2.61-7.78]), estrogens (OR, 4.00 [95\% CI, 1.06-15.03]), other combination therapies (OR, 4.04 [95\% CI, 1.88-8.69]), and gonadotropin-releasing hormone agonists (OR, 1.93 [95\% CI, 1.20-3.10]).

DESIGN, SETTING, AND PARTICIPANTS: We conducted a case-control study of 153 cases with unexplained HBM recruited from 4 UK centers by screening 219 088 DXA scans. A total of 138 first-degree relatives (of whom 51 had HBM) and 39 spouses were also recruited. Unaffected individuals served as controls. MAIN OUTCOME MEASURES: We measured fat mass, by DXA, and bone turnover markers. RESULTS: Among women, fat mass was inversely related to age in controls (P = .01), but not in HBM cases (P = .96) in whom mean fat mass was 8.9 [95\% CI 4.7, 13.0] kg higher compared with controls (fully adjusted mean difference, P {\textless} .001). Increased fat mass in male HBM cases was less marked (gender interaction P = .03). Compared with controls, lean mass was also increased in female HBM cases (by 3.3 [1.2, 5.4] kg; P {\textless} .002); however, lean mass increases were less marked than fat mass increases, resulting in 4.5\% lower percentage lean mass in HBM cases (P {\textless} .001).

The cost implications for patient care and budgetary management are unclear. AIM: To investigate whether caring for patients with specific disease combinations increases or decreases primary care costs compared with treating separate patients with one condition each. DESIGN: Retrospective observational study using data on 86 100 patients in the General Practice Research Database. METHOD: Annual primary care cost was estimated for each patient including consultations, medication, and investigations. Patients with comorbidity were defined as those with a current diagnosis of more than one chronic condition in the Quality and Outcomes Framework. Multiple regression modelling was used to identify, for three age groups, disease combinations that increase (cost-increasing) or decrease (cost-limiting) cost compared with treating each condition separately. RESULTS: Twenty per cent of patients had at least two chronic conditions. All conditions were found to be both cost-increasing and cost-limiting when co-occurring with other conditions except dementia, which is only cost-limiting. Depression is the most important cost-increasing condition when co-occurring with a range of conditions. Hypertension is cost-limiting, particularly when co-occurring with other cardiovascular conditions. CONCLUSION: Three categories of comorbidity emerge, those that are: cost-increasing, mainly due to a combination of depression with physical comorbidity; cost-limiting because treatment for the conditions overlap; and cost-limiting for no apparent reason but possibly because of inadequate care.

We explored the relation between use of metformin or other anti-diabetic drugs and the risk of esophageal cancer. METHODS: We conducted a case-control analysis in the UK-based general practice research database (GPRD, now clinical practice research datalink, CPRD). Cases were individuals with an incident diagnosis of esophageal cancer between 1994 and 2010 at age 40-89 years. Ten controls per case were matched on age, sex, calendar time, general practice, and number of years of active history in the GPRD prior to the index date. Various potential confounders including diabetes mellitus, gastro-esophageal reflux, and use of proton-pump inhibitors were evaluated in univariate models, and the final results were adjusted for BMI and smoking. Results are presented as odds ratios (ORs) with 95 \% confidence intervals (CI). RESULTS: Long-term use (≥30 prescriptions) of metformin was not associated with a materially altered risk of esophageal cancer (adj.

Rates of cancer diagnosed through unplanned admissions vary within and between countries, suggesting potential inconsistencies in the quality of care. To reduce diagnoses by this route and improve patient outcomes, high risk patient groups must be identified. This cross-sectional observational study determined the incidence of first-ever diagnoses of cancer by emergency (unplanned) admission and identified patient-level risk factors for these diagnoses in England. METHODS: Data for 74,763 randomly selected patients at 457 general practices between 1999 and 2008 were obtained from the General Practice Research Database (GPRD), including integrated Hospital Episode Statistics (HES) data and Office for National Statistics (ONS) mortality data. The proportion of first-ever diagnoses by emergency admission out of all recorded first cancer diagnoses by any route was analysed by patient characteristics. RESULTS: Diagnosis by emergency admission was recorded in 13.9\% of patients diagnosed with cancer for the first time (n = 817/5870). The incidence of first cases by the emergency route was 2.51 patients per 10,000 person years. In adjusted regression analyses, patients of older age (p {\textless} 0.0001), living in the most deprived areas (RR 1.93, 95\% CI 1.51 to 2.47; p {\textless} 0.0001) or who had a total Charlson score of 1 compared to 0 (RR 1.34, 95\% CI 1.06 to 1.69; p = 0.014) were most at risk of diagnosis by emergency admission. Patients with more prior (all-cause) emergency admissions were less at risk of subsequent diagnosis by the emergency route (RR 0.31 per prior emergency admission, 95\% CI 0.20 to 0.46; p {\textless} 0.0001). CONCLUSIONS: A much lower incidence of first-ever cancer diagnoses by emergency admission was found compared with previous studies.

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.

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.

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.

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.

OBJECTIVES: This study aims to quantify the risks associated with nonelective colorectal resection up to 1 year after surgery in elderly patients. DESIGN: This is a population-based observational study. SETTING: Data were obtained from the Hospital Episode Statistics database. POPULATION: All patients aged 70 years and older who underwent a nonelective colorectal resection in an English National Health Service Trust hospital between April 2001 and March 2008 were included. MAIN OUTCOME MEASURES: : The primary outcomes measured were 30-day in hospital mortality, 365-day mortality, unplanned readmission within 28 days of discharge, and duration of hospital stay. RESULTS: During the study period, 36,767 nonelective colorectal resections were performed in patients aged ≥ 70 years in England. Patients were classified into 3 age groups: A (70-75 years), B (76-80 years), and C (>80 years). Thirty-day mortality was 17.0%, 23.3%, and 31.0% in groups A, B, and C (p < 0.001). The overall 30-day medical complication rate was 33.7%, and the reoperation rate was 6.3%. Cardiac and respiratory complications were significantly higher in group C (22.2% and 18.2%, p < 0.001). Mortality in Group C was 51.2% at 1-year postsurgery. Advanced age was an independent determinant of mortality in risk-adjusted regression analyses. LIMITATIONS: This is a retrospective analysis of a prospective database. Stage of disease at presentation, severity of complications, and cause of death cannot be ascertained from this database.

The Global Burden of Disease (GBD) studies done in 1990 and 2000 have been the only studies to quantify non-fatal health outcomes across an exhaustive set of disorders at the global and regional level. Neither effort quantified uncertainty in prevalence or years lived with disability (YLDs). METHODS: Of the 291 diseases and injuries in the GBD cause list, 289 cause disability. For 1160 sequelae of the 289 diseases and injuries, we undertook a systematic analysis of prevalence, incidence, remission, duration, and excess mortality. Sources included published studies, case notification, population-based cancer registries, other disease registries, antenatal clinic serosurveillance, hospital discharge data, ambulatory care data, household surveys, other surveys, and cohort studies. For most sequelae, we used a Bayesian meta-regression method, DisMod-MR, designed to address key limitations in descriptive epidemiological data, including missing data, inconsistency, and large methodological variation between data sources. For some disorders, we used natural history models, geospatial models, back-calculation models (models calculating incidence from population mortality rates and case fatality), or registration completeness models (models adjusting for incomplete registration with health-system access and other covariates). Disability weights for 220 unique health states were used to capture the severity of health loss. YLDs by cause at age, sex, country, and year levels were adjusted for comorbidity with simulation methods. We included uncertainty estimates at all stages of the analysis. FINDINGS: Global prevalence for all ages combined in 2010 across the 1160 sequelae ranged from fewer than one case per 1 million people to 350,000 cases per 1 million people. Prevalence and severity of health loss were weakly correlated (correlation coefficient -0·37). In 2010, there were 777 million YLDs from all causes, up from 583 million in 1990. The main contributors to global YLDs were mental and behavioural disorders, musculoskeletal disorders, and diabetes or endocrine diseases. The leading specific causes of YLDs were much the same in 2010 as they were in 1990: low back pain, major depressive disorder, iron-deficiency anaemia, neck pain, chronic obstructive pulmonary disease, anxiety disorders, migraine, diabetes, and falls. Age-specific prevalence of YLDs increased with age in all regions and has decreased slightly from 1990 to 2010. Regional patterns of the leading causes of YLDs were more similar compared with years of life lost due to premature mortality. Neglected tropical diseases, HIV/AIDS, tuberculosis, malaria, and anaemia were important causes of YLDs in sub-Saharan Africa. INTERPRETATION: Rates of YLDs per 100,000 people have remained largely constant over time but rise steadily with age. Population growth and ageing have increased YLD numbers and crude rates over the past two decades. Prevalences of the most common causes of YLDs, such as mental and behavioural disorders and musculoskeletal disorders, have not decreased. Health systems will need to address the needs of the rising numbers of individuals with a range of disorders that largely cause disability but not mortality. Quantification of the burden of non-fatal health outcomes will be crucial to understand how well health systems are responding to these challenges. Effective and affordable strategies to deal with this rising burden are an urgent priority for health systems in most parts of the world.

We describe the incidence of hospital acquired adverse events in radical cystectomy, and characterize its relationship with in-hospital mortality, length of stay and hospitalization costs. MATERIALS AND METHODS: We identified 10,856 patients who underwent radical cystectomy for bladder cancer at 1,175 hospitals in the Nationwide Inpatient Sample from 2001 to 2008. We used hospital claims to identify adverse events for accidental puncture, decubitus ulcer, deep vein thrombosis/pulmonary embolus, methicillin-resistant Staphylococcus aureus, Clostridium difficile, surgical site infection and sepsis. Logistic regression and generalized estimating equation models were used to test the associations of hospital acquired adverse events with mortality, predicted prolonged length of stay and total hospitalization costs. RESULTS: Hospital acquired adverse events occurred in 11.3\% of all patients undergoing radical cystectomy (1,228). Adverse events were associated with a higher odds of in-hospital death (OR 8.07, p{\textless}0.001), adjusted prolonged length of stay (41.3\%) and total costs (\$54,242 vs \$26,306; p{\textless}0.001) compared to no adverse events on multivariate analysis. The incremental total costs attributable to hospital acquired adverse events were \$43.8 million. Postoperative sepsis was associated with the highest risk of mortality (OR 17.56, p{\textless}0.001), predicted prolonged length of stay (62.22\%) and adjusted total cost (\$79,613). CONCLUSIONS: With hospital acquired adverse events occurring in approximately 11\% of radical cystectomy cases, they pose a significant risk of in-hospital mortality and higher hospitalization costs. Therefore, increased attention is needed to reduce adverse events by improving patient safety, while understanding the economic implications for tertiary referral centers with possible policy changes such as denial of payment for hospital acquired adverse events.}, language = {eng}, number = {6}, journal = {The Journal of Urology}, author = {Kim, Simon P. and Shah, Nilay D. and Karnes, R.

Influenza infection is associated with high rates of complicated illness including pneumonia, heart attacks and strokes in the 65+ population. Changes in both innate and adaptive immune function not only converge in the reduced response to vaccination and protection against influenza, but present significant challenges to new vaccine development. In older adults, the goal of vaccination is more realistically targeted to providing clinical protection against disease rather sterilizing immunity. Correlates of clinical protection may not be measured using standard techniques such as antibody titres to predict vaccine efficacy. Further, antibody responses to vaccination as a correlate of protection may fail to detect important changes in cellular immunity and enhanced vaccine-mediated protection against influenza illness in older people.

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.

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).

The study cohort included AF patients aged 40 years and older included in the UK General Practice Research Database.

We evaluated the association between use of ICS-containing products, specifically fluticasone propionate/salmeterol fixed-dose combination (FSC), and incidence of cataracts and glaucoma among patients with COPD in a large electronic medical record database in the United Kingdom. METHODS: We identified a cohort of patients aged 45 years and over with COPD in the General Practice Research Database (GPRD) between 2003 and 2006. Cases of incident cataracts or glaucoma were defined based on diagnosis and procedure codes and matched to controls from the risk set to estimate odds ratios (OR) and 95\% confidence intervals (CI). The association with FSC or ICS exposure was modeled using conditional logistic regression. Medication exposure was assessed with respect to recency, duration, and number of prescriptions prior to the index date. Average daily dose was defined as none, low (1-250 mcg), medium (251-500 mcg), high (501-1000 mcg), or very high (1001+ mcg) using fluticasone propionate (FP) equivalents. RESULTS: We identified 2941 incident cataract cases and 327 incident glaucoma cases in the COPD cohort (n = 53,191). FSC or ICS prescriptions were not associated with risk of incident cataracts or glaucoma for any exposure category, after adjusting for confounders. We observed a lack of a dose response in all analyses, where low dose was the reference group. The odds of cataracts associated with FSC dose were medium OR: 1.1 (95\% CI: 0.9-1.4); high OR: 1.2 (95\% CI: 0.9-1.5); and very high OR: 1.2 (95\% CI: 0.9-1.7).

The literature on the timing of cancer code appearance in general practice records is scanty but suggests that there may be substantial error by comparison with actual dates of clinical onset. OBJECTIVES: To assess the accuracy of codes for esophageal cancer in the GPRD and to determine whether it was possible to infer clinical date of onset. METHODS: A reviewer adjudicated the records of women with codes for esophageal cancer from 1996 to 2008 by using chronological GPRD listings of codes for diagnoses, services, and tests. GPRD staff sought reviews by the general practices for 75 women whom the reviewer classified as having esophageal cancer and 25 classified as not having the condition. RESULTS: Essentially all cases bearing a code for the condition had esophageal cancer. Where data were available to permit dating of clinical onset (75\% of cases), the result agreed with the date recorded in the clinical record to within 60 days in 89\% of cases. The remaining 25\% of cases had little or no clinical information and could not be dated. Clinical onset preceded the first appearance of a cancer code by more than 6 months in 10\% of cases.

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.}, language = {eng}, number = {12}, journal = {Heart (British Cardiac Society)}, author = {Hippisley-Cox, Julia and Coupland, Carol}, month = jun, year = {2010}, pmid = {20489220}, keywords = {Acute Kidney Injury, Adult, Aged, Aged, 80 and over, Algorithms, Body Mass Index, Cataract, Drug-Induced Liver Injury, England, Epidemiologic Methods, Female, Humans, Hydroxymethylglutaryl-CoA Reductase Inhibitors, Male, Middle Aged, Muscular Diseases, Wales}, pages = {939--947} }

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.

Prediction of such events is highly desirable in clinical routine for prevention. This paper presents a novel prediction method of acute symptomatic hypotension in which the photoplethysmographic signal is analyzed with respect to changes in amplitude, reflecting vasoconstriction, and cardiac output. The method is based on a statistical model in which the noise is assumed to have Laplacian amplitude distribution. The performance is evaluated on 11 hypotension-prone patients who underwent hemodialysis treatment, resulting in seven events with acute symptomatic hypotension and 17 without. The photoplethysmographic signal was continuously acquired during treatment as was information on blood pressure and oxygen saturation. Using leave-one-out cross validation, the proposed method predicted six out of seven hypotensive events, while producing 1 false prediction out of 17 possible. The performance was achieved when the prediction threshold was chosen to be in the range 57%-65% of the photoplethysmographic envelope at treatment onset.}, bibtype = {article}, author = {Solem, Kristian and Olde, Bo and Sörnmo, Leif}, journal = {IEEE transactions on bio-medical engineering}, number = {7} }

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.

The objectives of this study were: (i) to test if constant and accelerated hippocampal loss can be detected in Alzheimer's disease, mild cognitive impairment and normal ageing over short periods, e.g. 6-12 months, with MRI in the large multicentre setting of the Alzheimer's Disease Neuroimaging Initiative (ADNI); (ii) to determine the extent to which the polymorphism of the apolipoprotein E (ApoE) gene modulates hippocampal change; and (iii) to determine if rates of hippocampal loss correlate with cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease, such as the beta-amyloid (Abeta(1-42)) and tau proteins (tau). The MRI multicentre study included 112 cognitive normal elderly individuals, 226 mild cognitive impairment and 96 Alzheimer's disease patients who all had at least three successive MRI scans, involving 47 different imaging centres. The mild cognitive impairment and Alzheimer's disease groups showed hippocampal volume loss over 6 months and accelerated loss over 1 year. Moreover, increased rates of hippocampal loss were associated with presence of the ApoE allele epsilon4 gene in Alzheimer's disease and lower CSF Abeta(1-42) in mild cognitive impairment, irrespective of ApoE genotype, whereas relations with tau were only trends. The power to measure hippocampal change was improved by exploiting correlations statistically between successive MRI observations. The demonstration of considerable hippocampal loss in mild cognitive impairment and Alzheimer's disease patients over only 6 months and accelerated loss over 12 months illustrates the power of MRI to track morphological brain changes over time in a large multisite setting. Furthermore, the relations between faster hippocampal loss in the presence of ApoE allele epsilon4 and decreased CSF Abeta(1-42) supports the concept that increased hippocampal loss is an indicator of Alzheimer's disease pathology and a potential marker for the efficacy of therapeutic interventions in Alzheimer's disease.}, bibtype = {article}, author = {Schuff, N and Woerner, N and Boreta, L and Kornfield, T and Shaw, L M and Trojanowski, J Q and Thompson, P M and Jack Jr., C R and Weiner, M W}, journal = {Brain}, number = {Pt 4} }

METHODS: Using the Nationwide Inpatient Sample, we analyzed data for both LC and OC between 1997 and 2006. Cholecystectomies performed as part of another primary procedure were excluded. Using procedure-specific codes, we calculated annual national volumes for both open and laparoscopic cholecystectomies for the time period under review and the associated in-hospital mortality following both of these procedures. Using logistic regression modeling, we then analyzed selected patient and institutional characteristics to determine if a significant association existed between these factors and in-hospital mortality. RESULTS: There was a 16\% increase in the volume of LC and a corresponding decrease in open procedures over the 10 years under review. In 2006, 12\% of cholecystectomies were still performed using an open approach and the associated mortality remained significantly higher than that seen with LC. Overall, after adjusting for patient and hospital characteristics, the mortality for OC was higher than that for LC (OR 4.57; 95\% CI, 4.37-4.79, p {\textless} 0.001). Age ({\textgreater}60 years), male gender, non-elective admission, admission source, and a primary diagnosis other than cholelithiasis were all independently associated with increased mortality. The average mortality rate associated with conversion from LC to OC was found to be 0.7\%.

AIM: To investigate recent trends in the recorded incidence, lifetime prevalence and prescribing of adrenaline for anaphylaxis in England. METHODS: QRESEARCH is one of the world's largest national aggregated health databases containing the records of over nine million patients. We extracted data on all patients with a recorded diagnosis of anaphylaxis and calculated annual age-sex standardized incidence and lifetime period prevalence rates for each year from 2001-2005. We also analysed trends in adrenaline prescribing in those with a recorded diagnosis of anaphylaxis. National population figures were used to estimate numbers of people in England that have experienced anaphylaxis at some point in their lives. RESULTS: The age-sex standardized incidence of anaphylaxis was 6.7 per 100,000 person-years in 2001 and increased by 19\% to 7.9 in 2005. Lifetime age-sex standardized prevalence of a recorded diagnosis of anaphylaxis was 50.0 per 100,000 in 2001 and increased by 51\% to 75.5 in 2005. Prescribing of adrenaline increased by 97\% over this period. By the end of 2005 there were an estimated 37,800 people that had experienced anaphylaxis at some point in their lives.

We sought to further clarify this association. METHODS: A retrospective cohort study was performed using the General Practice Research Database of the United Kingdom. Patients with a prior diagnosis of ovarian, uterine, or cervical cancers were compared with control patients without a prior gynecologic malignancy. The primary outcome was a diagnosis of CRC. Poisson regression analysis was used to assess the effects of potential confounders. RESULTS: The study included 1995 ovarian, 1348 uterine, and 1101 cervical cancer patients and 7980, 5392, and 4404 matched control patients, respectively. The adjusted incidence rate ratio (IRR) of CRC among ovarian cancer patients was 2.90 [95\% confidence intervals (CI) 1.45-5.82]. Five of 10 cases of CRC in ovarian cancer patients were diagnosed within 6 months of the cancer diagnosis with an adjusted IRR of 8.0 (95\% CI 1.9-33.6). Excluding the initial 6 months of follow-up after the diagnosis of ovarian cancer, the adjusted IRR was 1.6 (95\% CI 0.76-5.03).

DESIGN: Cohort study. SETTING: UK General Practice Research Database. Patients 762 325 patients aged 15 years and older, registered with 128 general practices between 1994 and 2000. First occurrences of haematuria, haemoptysis, dysphagia, and rectal bleeding were identified in patients with no previous cancer diagnosis. MAIN OUTCOME MEASURE: Positive predictive value of first occurrence of haematuria, haemoptysis, dysphagia, or rectal bleeding for diagnoses of neoplasms of the urinary tract, respiratory tract, oesophagus, or colon and rectum during three years after symptom onset. Likelihood ratio and sensitivity were also estimated. RESULTS: 11.108 first occurrences of haematuria were associated with 472 new diagnoses of urinary tract cancers in men and 162 in women, giving overall three year positive predictive values of 7.4\% (95\% confidence interval 6.8\% to 8.1\%) in men and 3.4\% (2.9\% to 4.0\%) in women. After 4812 new episodes of haemoptysis, 220 diagnoses of respiratory tract cancer were made in men (positive predictive value 7.5\%, 6.6\% to 8.5\%) and 81 in women (4.3\%, 3.4\% to 5.3\%). After 5999 new diagnoses of dysphagia, 150 diagnoses of oesophageal cancer were made in men (positive predictive value 5.7\%, 4.9\% to 6.7\%) and 81 in women (2.4\%, 1.9 to 3.0\%). After 15 289 episodes of rectal bleeding, 184 diagnoses of colorectal cancer were made in men (positive predictive value 2.4\%, 2.1\% to 2.8\%) and 154 in women (2.0\%, 1.7\% to 2.3\%). Predictive values increased with age and were strikingly high, for example, in men with haemoptysis aged 75-84 (17.1\%, 13.5\% to 21.1\%) and in men with dysphagia aged 65-74 (9.0\%, 6.8\% to 11.7\%).

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.

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.}, language = {eng}, number = {9}, journal = {Osteoporosis international: a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA}, author = {Shepherd, J.

METHODS: A matched cohort study was implemented in 123 general practices using the General Practice Research Database. Irritable bowel syndrome cases (n = 1827) and controls (n = 3654) were compared for 2 years before and 6 years after diagnosis.

METHODS: We identified 930 people with PBC and 9202 age- and sex-matched control subjects. We used Cox regression to estimate the hazard ratios for any fracture, hip fracture, and ulna/radius fracture in the PBC cohort compared with the general population. RESULTS: There were approximately 2-fold relative increases in the risk of any fracture, hip fracture, and ulna/radius fracture for the PBC cohort compared with the general population (hazard ratio [HR], 2.03; 95\% confidence interval [CI]: 1.70-2.44; HR 2.14 (95\% CI: 1.40-3.28), and HR, 1.96; 95\% CI: 1.42-2.71, respectively).

Since the energetic and nutritional demands of pregnancy and breastfeeding render reproductive costs much higher in women than in men, women with a large number of children should show signs of deterioration in condition, while men with large families should not. However, whether reproductive costs reduce longevity in women is still questionable, and in men this issue has not been adequately addressed. In addition, since sons are energetically more expensive to produce than daughters, having sons should have a more pronounced negative impact on maternal longevity than having daughters. Here we document a striking disparity in the impact of children on the life span of mothers and fathers in a Polish rural population. We show for the first time that number of daughters was positively related to a longer life span of their fathers, increasing their longevity on average by 74 weeks per daughter born, while number of sons did not have a significant effect on paternal longevity. In contrast, in women, the number of daughters and number of sons reduced maternal longevity and did so to the same extent, on average by 95 weeks per son or daughter, indicating that for women, the costs of having sons and daughters are similar.}, bibtype = {article}, author = {Jasienska, G and Nenko, I and Jasienski, M}, journal = {Am J Hum Biol}, number = {3} }

The occurrence of different respiratory infections varies widely at different ages but we do not know whether prescribing has reduced equally in all age groups. OBJECTIVE: We aimed to determine how reductions in consultation rates and antibiotic prescribing varied with age for different respiratory infections. METHODS: Data were abstracted from the General Practice Research Database for 108 general practices in the UK (mean registered population 642 685). We estimated age-specific changes between 1995 and 2000 in consultation rates, and the proportion of consultations resulting in an antibiotic prescription for 'all respiratory infections' and for 'sore throat', 'ear infection', 'bronchitis' and 'chest infection'. RESULTS: Consultation rates for 'all respiratory infections' declined in all age groups with the greatest decreases in children aged 1-4 years (41\%), 5-10 year olds (53\%) and 11-16 year olds (54\%), whereas at 75-84 years the reduction was 28\%. The pattern of greater reductions in children held for each separate condition even though the age of peak incidence varied. The relative reduction in antibiotic prescribing was greatest at 1-4 years (18\%), 5-10 years (17\%) and 11-16 years (17\%), compared with 5\% at 75-84 years. Antibiotic prescribing decreased most for sore throat and this was observed at all ages particularly in 5-10 year olds (relative reduction, 32\%).

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.

METHODS: Cohort study of patients prescribed NSAIDs between June 1987 and January 2000. Exposure to Newer and Older non-specific NSAIDs was identified, and risk factors evaluated for each patient. Results of multiple covariate analyses and the propensity scoring technique to assess potential channelling bias in comparisons between Newer and Older non-specific NSAIDs were compared. RESULTS: This study included 7.1 thousand patient years (tpy) exposure to meloxicam, 1.6 tpy exposure to coxibs, and 628 tpy exposure to Older non-specific NSAIDs. Patients receiving Newer NSAIDs were older, more likely to have a history of GI symptoms, and at higher risk for GI complications. Adjusting for these risk factors reduced the relative risks of UGIH on meloxicam and coxibs versus Older non-specific NSAIDs to 0.84 (95\%CI 0.60, 1.17) and 0.36 (0.14, 0.97) respectively. CONCLUSIONS: Channelling towards high GI risk patients occurred in the prescribing of Newer NSAIDs. Propensity scores highlighted the markedly different risk profiles of users of Newer and Older non-specific NSAID.

DESIGN: Case-control study. SETTING: The study was part of the Longevity Genes Project at Albert Einstein College of Medicine. PARTICIPANTS: Centenarians (n=145), offspring of centenarians (n=180), and spouses of the offspring of centenarians (n=75) as a control group. Two additional groups served as controls: age-matched Ashkenazi Jews, and an age-matched control group from the Third National Health and Nutrition Examination Survey. MEASUREMENTS: Self-reported family history of longevity; prevalence of hypertension, diabetes mellitus, heart attacks, and strokes; and objective measurements of body mass index and fat mass. RESULTS: Parents of centenarians (born in approximately 1870) had a markedly greater ( approximately sevenfold) "risk" for longevity (reaching ages 90-99), supporting the notion that genetics contributed to longevity in these families. The offspring of long-lived parents had significantly lower prevalence of hypertension (by 23%), diabetes mellitus (by 50%), heart attacks (by 60%), and strokes (no events reported) than several age-matched control groups. CONCLUSION: Offspring of centenarians may inherit significantly better health. The authors suggest that a cohort of these subjects and their spouses is ideal to study the phenotype and genotype of longevity and its interaction with the environment.}, bibtype = {article}, author = {Atzmon, G and Schechter, C and Greiner, W and Davidson, D and Rennert, G and Barzilai, N}, journal = {J Am Geriatr Soc}, number = {2} }

OBJECTIVES: To evaluate the frequency that other medical conditions are associated with a new venous leg ulcer. METHODS: We studied a 10\% random sample of elderly patients registered in the General Practice Research Database between 1988 and 1996. We describe the frequency of medical conditions using simple percentages. In order to assess the associations between medical conditions and the onset of a venous leg ulcer, we used logistic regression models. RESULTS: Several medical conditions occur commonly in patients who develop venous leg ulcers, including anaemia, angina, asthma, cellulitis of the lower extremity, depression, diabetes, limb oedema, hypertension, osteoarthritis, pneumonia and urinary tract infection. After statistical adjustment many medical conditions were significantly associated with those who had recent onset of a venous leg ulcer, including asthma, cellulitis of the lower extremity, congestive heart failure, diabetes, deep venous thrombosis, lower limb oedema, osteoarthritis, peripheral vascular arterial disease of the lower extremity, rheumatoid arthritis, history of hip surgery, and history of venous surgery/ligation. Unexpectedly, some illnesses were inversely associated with those that had recent onset of a venous leg ulcer, including angina, cerebral vascular accident, depression, malignancy, myocardial infarction, pneumonia and urinary tract infection.

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.

Family studies revealed that more than one-third of the DAT cases are members of one hamula (tribal group) within Wadi Ara. To map chromosomal loci contributing to DAT susceptibility, we conducted a 10 cM scan in a series of five cases and five controls selected from this hamula. Markers from 18 chromosomal regions showed significant allelic association with DAT (P<0.05). Locations on chromosomes 2, 9 and 10 remained significant after testing additional affected and non-demented individuals. Significant associations were also observed for markers on chromosome 12 which overlap with a locus implicated in previous genome scans. Analysis of allele frequency distributions for 12 markers spanning 20 cM on chromosome 9 narrowed the possible location of an DAT susceptibility gene to a 13 cM interval between D9S157 and D9S259 (most significant result: P = 2.3 x 10(-7)). Analysis of 14 markers spanning 24 cM on chromosome 12 narrowed the possible location to a 14 cM interval distal to the LRP1 locus (most significant result: P = 1.3 x 10(-6)). Evidence for linkage on chromosome 9 stemmed primarily from excess homozygosity of marker alleles in cases compared with controls, suggesting that the gene at this location behaves in either a recessive or additive fashion. The unique characteristics of this community together with the emergent human genome data should allow for the rapid identification of DAT genes in these candidate regions.}, bibtype = {article}, author = {Farrer, L A and Bowirrat, A and Friedland, R P and Waraska, K and Korczyn, A D and Baldwin, C T}, journal = {Hum Mol Genet}, number = {4} }

The children of long-lived parents may therefore age more successfully than the children of short-lived parents. METHODS: We used three major cross-sectional population-based surveys to study the association of parental longevity with successful aging in offspring. The measures of aging were hand-grip strength, cognitive performance (Mini Mental State Examination and a cognitive composite score), self-reported diseases, and self-rated health. RESULTS: For every additional 10 years the parents lived, their children's grip strength increased by 0.32 kg (95% CI = 0.00-0.63), Mini Mental State Examination score by 0.20 points (95% CI = 0.03-0.37), and cognitive composite score by 0.24 points (95% CI = 0.07-0.40). A 10-year increment of parental life was associated with a reduction by approximately 0.20 in the adjusted odds ratio for their children having each of the following conditions: diabetes; hypertension; ischemic heart disease; heart failure; stroke; or fair, poor, or very poor self-rated health. Almost all the effects were seen solely in the cohort of 70+-year-olds, but not among middle-aged or nonagenarian subjects. CONCLUSIONS: Parental life span is positively associated with the children's physical and cognitive functioning and avoidance of some of the common chronic diseases. However, the effects are small and are seen among offspring who are elderly, but not among the middle-aged or the oldest old.}, bibtype = {article}, author = {Frederiksen, H and McGue, M and Jeune, B and Gaist, D and Nybo, H and Skytthe, A and Vaupel, J W and Christensen, K}, journal = {Epidemiology}, number = {3} }

As a result, many have recommended local field radiotherapy. For infratentorial ependymoma, there is controversy regarding what constitutes the local field. Some radiation oncologists advocate coverage of the entire posterior fossa, whereas others recommend radiotherapy to the tumor bed and a safety margin. METHODS AND MATERIALS: From 1984 to 1998, 28 patients with posterior fossa ependymoma were diagnosed at our institution. There were 18 males and 10 females with a median age of 12 years (range, 2-81 years). Four patients (14%) had high-grade ependymoma and 3 (11%) had M+ disease at initial diagnosis. Gross total resection was achieved in 17 (61%) and postoperative radiotherapy (RT) was given to 22 (77%). Radiotherapy fields were craniospinal in 10, whole brain in 1, posterior fossa in 2, and tumor bed with a 2-cm. margin in 9. Median dose to the primary site was 54 Gy (range, 45-55 Gy). All 4 patients with high-grade ependymoma received craniospinal RT. Six patients did not receive RT after surgery. Magnetic resonance imaging (MRI) or computed tomography (CT) scans of the brain at initial diagnosis were compared to MRI or CT scans of patients at relapse to determine if the local relapse was in the tumor bed or nontumor bed posterior fossa. Median follow-up was 127 months (range, 14-188 months). RESULTS: Six patients have relapsed. For the 11 patients who had craniospinal or whole brain radiotherapy (RT), 3 recurred (tumor bed 1, spine 1, nontumor bed posterior fossa + spine 1). Both patients who failed in the spine had high-grade tumors. Neither of the 2 treated with posterior fossa fields relapsed. For the 9 patients who had tumor bed RT alone and the 6 who did not receive RT, there were 3 relapses; all were in the tumor bed. There were no relapses in the nontumor bed posterior fossa. CONCLUSION: For nondisseminated, low-grade infratentorial ependymoma, the radiotherapy volume does not need to include the entire posterior fossa. This information can be used to minimize late effects of RT in the era of three-dimensional (conformal) radiotherapy. No conclusion can be reached regarding the appropriate local field for high-grade infratentorial ependymoma because of the small number of patients.}, bibtype = {article}, author = {Paulino, A C}, journal = {International Journal of Radiation Oncology Biology Physics}, number = {3} }

The method is highly reliable, and three patterns of peaks (QM376-400, QM780-790 and QM480) appeared to be representative for germ-line polymorphisms, as suggested by the results obtained in nine couples of monozygotic twins and four three-generation families. The frequency of these polymorphic peaks was studied in two different age groups (100 young subjects and 69 centenarians). In two out of the three regions (QM376-400 and QM480) a significant increase in homozygote genotypes frequency was observed in centenarians.

METHODS The study was carried out in a prison for detained persons and short term prisoners. Using a standardized questionnaire, we recorded the characteristics of all male detainees and prisoners arriving in the prison between 1989 and 1995. The information collected concerned: demographic data, level of education and professional status, reasons for detention or imprisonment, social and family background, lifestyle, medical and psychiatric history, suicide attempts and illicit use of drugs. The characteristics of the study population were compared with those found in the general regional population. We analyzed developing trends in the health status of the prison population as well as their socio-economic profile over a period of seven years (1989 to 1995). RESULTS A total of 14,785 questionnaires were analyzed. Of the study population, 56\% had no professional qualification, and 62\% was unemployed. About two-thirds of the inmates presented psychiatric problems or problems with illicit drug use (one or several drugs). Amongst these, 70\% had not had any form of care -neither therapeutic nor educational- before their arrival in prison. Between 1989 and 1995, the proportion of drug users increased by 30\%. A parallel increase was observed in the level of unemployment and in the frequency of mental problems. CONCLUSIONS Our results suggest a need for therapeutic and educational care to be provided for prison inmates. This poses a problem which needs to be addressed in terms of public health. The study also illustrates the usefulness of a standardised questionnaire for each arrival. The systematic use of such a tool would make it possible to identify inmates'needs and to propose adapted care solutions.}, number = {3}, urldate = {2012-05-10}, journal = {Revue d'épidémiologie et de santé publique}, author = {Duhamel, A and Renard, J M and Nuttens, M C and Devos, P and Beuscart, R and Archer, E}, month = jun, year = {2001}, pmid = {11427826}, keywords = {*Health Status, Adolescent, Adult, Aged, Aged, 80 and over, Crime, Crime/statistics \& numerical data/trends, Educational Status, Family, Family/psychology, France, France/epidemiology, Health Status, Health Surveys, Humans, Interview, Psychological, Life Style, Male, Marital Status, Marital Status/statistics \& numerical data, Mental Disorders, Mental Disorders/diagnosis/epidemiology, Middle Aged, Needs Assessment, Occupations, Occupations/statistics \& numerical data, Prisoners, Prisoners/education/psychology/*statistics \& numerical data, Questionnaires, Risk Factors, Socioeconomic Factors, Substance-Related Disorders, Substance-Related Disorders/epidemiology, Suicide, Attempted, Suicide, Attempted/statistics \& numerical data, Surveys and Questionnaires}, pages = {229--238}, }

METHODS: The study group consisted of 215 healthy white women aged 20 to 85 years and 51 white women aged 60 to 86 years with osteoporotic fractures. Fifty-two healthy women aged 50 to 85 years were randomly selected from the healthy cohort as the control group. All the women had calcaneal quantitative ultrasonic measurements. The women with osteoporotic fractures and the control group also had proximal femur and lumbar anteroposterior spine bone mineral density measurements using dual X-ray absorptiometry. Bone mineral density was also measured in a subgroup of 54 women at the calcaneus. RESULTS: There was a significant inverse correlation of broadband ultrasound attenuation and speed of sound with age (P {\textless} .001). Short-term measurement precision values expressed as coefficients of variation were 1.72\% for broadband ultrasound attenuation and 0.64\% for speed of sound, and standardized short-term precision values were 6.09\% for broadband ultrasound attenuation and 3.87\% for speed of sound. The correlations between the quantitative ultrasonic parameters and calcaneal bone mineral density were 0.69 (P = .0001) for broadband ultrasound attenuation and 0.45 (P = .0008) for speed of sound. Both quantitative ultrasonic parameters and all bone mineral density measurements of the hip and spine differed significantly between the control and osteoporotic fracture groups (P {\textless} .01). Age-, weight-, and height-adjusted odds ratios per SD decrease were as follows: broadband ultrasound attenuation, 1.79; speed of sound, 1.83; spine bone mineral density, 2.34; femoral neck bone mineral density, 1.69; and total hip bone mineral density, 1.85. The areas under the receiver operating characteristic curve for quantitative ultrasound parameters and bone mineral density measurements were close, ranging from 0.75 to 0.80. CONCLUSIONS: This new quantitative ultrasound system can detect age- and menopause-related influences on skeletal status and can discriminate healthy women from those with osteoporotic fractures in a manner comparable with that of bone mineral density measurement by dual X-ray absorptiometry.}, language = {eng}, number = {11}, journal = {Journal of Ultrasound in Medicine: Official Journal of the American Institute of Ultrasound in Medicine}, author = {Njeh, C.

DESIGN: Analysis of data from the general practice research database. SETTING: England and Wales. PATIENTS: 1.4 million patients registered with 211 general practices. MAIN OUTCOME MEASURES: Age and sex specific prevalence rates of atrial fibrillation; percentage of patients with atrial fibrillation treated with oral anticoagulants or aspirin. RESULTS: The prevalence of atrial fibrillation in 1998 was 12.1/1000 in men and 12.7/1000 in women. Prevalence increased from less than 1/1000 in under 35 year olds to over 100/1000 in those aged 85 years and over. There was a 22\% increase in the age standardised prevalence of atrial fibrillation in men and a 14\% increase in women between 1994 and 1998. The percentage of patients prescribed oral anticoagulants increased from 20\% to 34\% in men and from 17\% to 25\% in women. The percentage of men with atrial fibrillation prescribed aspirin increased from 26\% to 36\%, and the percentage of women increased from 24\% to 36\%. Applying the age and sex specific prevalence and treatment rates to the population gives an estimate of around 650 000 cases of atrial fibrillation in England and Wales. The greatest number of cases occurs in the 75-84 year old age group. CONCLUSIONS: The number of patients in the community with identified atrial fibrillation is increasing.

To further characterize the spectrum of BRCA1 mutations and the impact of BRCA2 mutations in Poland, we have analyzed 25 high-risk breast and/or ovarian cancer families from North-Eastern Poland for mutations in all coding exons of the BRCA1 and BRCA2 genes, using combined heteroduplex analysis/SSCP followed by direct DNA sequence analysis. Out of 25 probands a total of five (20%) carried three recurrent BRCA1 mutations (300T>G, 3819del5, 5382insC). The 300T>G mutation accounted for 60% (3/5) of BRCA1 mutations and allelotyping suggested a common founder of this mutation. No unique mutations were found. In addition, we identified three BRCA2 (12%) mutations, one recurrent 4075delGT, and two novel frameshift mutations, 7327ins/dupl19 and 9068delA. We conclude that 30% of high-risk families from North-Eastern Poland may be due to recurrent BRCA1 and unique BRCA2 mutations.

Starting from the observation that both mtDNA variability and Tyrosine hydroxylase (THO, stress-responder gene) variability are correlated with human longevity, we asked ourselves whether mechanisms similar to RR may exist in humans. As a first investigative step we have analyzed the distribution of the mtDNA inherited variants (haplogroups) according to THO genotypes in three sample groups of increasing ages (20-49 years; 50-80 years; centenarians). We found that the mtDNA haplogroups and the THO genotypes are associated randomly in the first group, while in the second group, and particularly in the centenarians, a non-random association is observed between the mtDNA and nuclear DNA variability. Moreover, in centenarians the U haplogroup is over-represented (p=0.012) in subjects carrying the THO genotype unfavorable to longevity. On the whole these findings are in line with the hypothesis that longevity requires particular interactions between mtDNA and nuclear DNA and do not exclude the possibility that an RR has been maintained throughout evolution and it is present in higher organisms.}, bibtype = {article}, author = {De Benedictis, G and Carrieri, G and Garasto, S and Rose, G and Varcasia, O and Bonafè, M and Franceschi, C and Jazwinski, S M}, journal = {Experimental gerontology}, number = {6-7} }

Two mutations in BRCA1 (185delAG and 5382insC) and one mutation in BRCA2 (6174delT) are common in the Ashkenazi Jewish population. One of these three mutations is present in approximately 2% of the Jewish population. Each mutation is associated with an increased risk of ovarian cancer, and it is expected that a significant proportion of Jewish women with ovarian cancer will carry one of these mutations. To estimate the proportion of ovarian cancers attributable to founding mutations in BRCA1 and BRCA2 in the Jewish population and the familial cancer risks associated with each, we interviewed 213 Jewish women with ovarian cancer at 11 medical centers in North America and Israel and offered these women genetic testing for the three founder mutations. To establish the presence of nonfounder mutations in this population, we also completed the protein-truncation test on exon 11 of BRCA1 and exons 10 and 11 of BRCA2. We obtained a detailed family history on all women we studied who had cancer and on a control population of 386 Ashkenazi Jewish women without ovarian or breast cancer. A founder mutation was present in 41.3% of the women we studied. The cumulative incidence of ovarian cancer to age 75 years was found to be 6.3% for female first-degree relatives of the patients with ovarian cancer, compared with 2.0% for the female relatives of healthy controls (relative risk 3.2; 95% CI 1.5-6.8; P=.002). The relative risk to age 75 years for breast cancer among the female first-degree relatives was 2.0 (95% CI 1.4-3.0; P=.0001).

The method, inspired by data mining methods, is based on discovery of recurrent patterns. We define a class of useful haplotype patterns in genetic case-control data and use the algorithm for finding disease-associated haplotypes. The haplotypes are ordered by their strength of association with the phenotype, and all haplotypes exceeding a given threshold level are used for prediction of disease susceptibility-gene location. The method is model-free, in the sense that it does not require (and is unable to utilize) any assumptions about the inheritance model of the disease. The statistical model is nonparametric. The haplotypes are allowed to contain gaps, which improves the method's robustness to mutations and to missing and erroneous data. Experimental studies with simulated microsatellite and SNP data show that the method has good localization power in data sets with large degrees of phenocopies and with lots of missing and erroneous data. The power of HPM is roughly identical for marker maps at a density of 3 single-nucleotide polymorphisms/cM or 1 microsatellite/cM. The capacity to handle high proportions of phenocopies makes the method promising for complex disease mapping. An example of correct disease susceptibility-gene localization with HPM is given with real marker data from families from the United Kingdom affected by type 1 diabetes. The method is extendable to include environmental covariates or phenotype measurements or to find several genes simultaneously.}, bibtype = {article}, author = {Toivonen, H T and Onkamo, P and Vasko, K and Ollikainen, V and Sevon, P and Mannila, H and Herr, M and Kere, J}, journal = {Am J Hum Genet}, number = {1} }

Additive decomposition of frailty into genetic and environmental components is used to estimate heritability in frailty. The estimate of the standard deviation of frailty from the pooled data is about 1.5. The hypothesis that variance in frailty and correlations of frailty for twins are similar in the data from all three countries is accepted. The estimate of narrow-sense heritability in frailty is about 0.5. The age trajectories of individual hazards are evaluated for all three populations of twins and both sexes. The results of our analysis confirm the presence of genetic influences on individual frailty and longevity.

In this study we describe the terminal extent of quadriceps tendon fibres where they insert into the patellae of adult rabbits, humans, dogs and sheep. Specimens were examined by scanning electron microscopy (SEM) and light microscopy (LM). To facilitate tracing of tendon fibres the specimens were decalcified for SEM, and polarised light microscopy (PLM) was used in the LM segment of the study. By SEM it was possible to identify mature bone by the presence of osteocytes and a lamellar organisation. PLM and SEM showed that, unlike tendon fibres elsewhere, those in the calcified fibrocartilage were not crimped. No specific cement line was identified by SEM. Tendon fibres interdigitated among separate bone lamellar systems, (osteons or marrow spaces), but did not merge with the collagen systems of individual lamellae. The interdigitation was more extensive and the margin between tendon and bone was less distinct in the anterior third of the insertion. The segment of calcified tendon which interdigitated with bone stained less intensely blue and was less cellular than the more proximal calcified fibrocartilage zone adjacent to the tidemark. Lamellar collagen fibres of the bony trabeculae in the anterior patella were unusually parallel and longitudinal in orientation, making distinction of interposed tendon fibres difficult on LM and PLM sections. LM, SEM and transmission electron microscopy of rabbit patellae at birth revealed that anterior quadriceps tendon fibres extended over the patella in a fibrous cellular layer. By 2 wk of age, this layer had acquired chondroid features (i.e. cell lacunae and metachromasia) and contained vessels extending from patellar marrow. At 6 wk of age, part of this fibrocartilaginous layer was replaced by mature bone and osteoid. In the young adult animal, the quadriceps tension interdigitates extensively with the patellar bone. This segment of the insertion is perhaps the remnant of calcified fibrocartilage which has been remodelled by bone formation.}, language = {eng}, journal = {Journal of Anatomy}, author = {Clark, J. and Stechschulte, D.

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).

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.}, bibtype = {article}, author = {Zamel, N and McClean, P A and Sandell, P R and Siminovitch, K A and Slutsky, A S}, journal = {Am J Respir Crit Care Med}, number = {6 Pt 1} }

DESIGN: A retrospective cohort study using data automatically recorded on general practitioners' office computers. SETTING: Some 600 general practices in the United Kingdom. SUBJECTS: 366,064 people who received erythromycin. MAIN OUTCOME MEASURE: Clinically documented cholestatic hepatitis of uncertain origin diagnosed 1-45 days after a prescription for erythromycin. RESULTS: There were 13 cases of cholestatic hepatitis of uncertain origin diagnosed within 45 days of receiving erythromycin which were either characteristic of or consistent with a syndrome previously described as being associated with this drug. CONCLUSION: The risk of cholestatic jaundice associated with erythromycin is estimated to be in the range of 3.6 per 100,000 users (95\% confidence interval, 1.9-6.1).}, language = {eng}, number = {9}, journal = {The Medical Journal of Australia}, author = {Derby, L.

The nature of the effusions was established on the basis of chemical, bacteriologic, and cytologic examination of pleural fluid; pleural biopsy; and clinical follow-up. All patients had high-frequency, real-time sonography performed by one of three sonographers who had no clinical information concerning the patients. The sonographer evaluated the images for internal echogenicity of the effusion, thickness of the pleura, and associated parenchymal lesions of the lung. The images were also printed out and interpreted a second time by the other two sonographers to reach a consensus. Our results showed that the two types of effusions could be distinguished on the basis of sonographic findings. Transudates were anechoic, whereas an anechoic effusion could be either a transudate or an exudate. Pleural effusions with complex septated, complex nonseptated, or homogeneously echogenic patterns were always exudates (p less than .01). Sonographic findings of thickened pleura and associated parenchymal lesions in the lung also were indicative of an exudate (p less than .01). Homogenous echogenic effusions were due to hemorrhagic effusion or empyema. Sonographic evidence of a pleural nodule was a specific finding in patients with a malignant effusion. We conclude that sonography is useful in determining the nature of pleural effusion.}, number = {1}, urldate = {2015-01-20TZ}, journal = {American Journal of Roentgenology}, author = {Yang, P C and Luh, K T and Chang, D B and Wu, H D and Yu, C J and Kuo, S H}, month = jul, year = {1992}, keywords = {Adolescent, Adult, Aged, Aged, 80 and over, Child, Child, Preschool, Female, Humans, Lung, Male, Middle Aged, Pleura, Pleural Effusion, Prospective Studies}, pages = {29--33} }

Of 331 specimens with hyperkalaemia, 71 were excluded because the specimens was haemolysed, old or contaminated. The laboratory served a population of 348,561 and during this time measured the plasma potassium on 25,016 occasions. Sixty-six outpatients and 20 neonates were not evaluated. The survey was undertaken on 86 of 102 inpatients (46 males), 48 of whom were over 66 years of age. Fifty-seven patients were admitted under a medical service and 29 under a surgical service. Fifty-nine had a single episode of hyperkalaemia. Thirty-two underwent a surgical procedure. The commonest contributing factor was impaired renal function which was present in 71 (83\%) patients. Although a definitive causative role for drugs could be identified in only five patients, in 52 (60\%) patients drugs were a contributing factor (potassium supplements 24, ACE inhibitors 16, nonsteroidal antiinflammatory drugs 12). Thirty-five of the 86 (41\%) patients died during their hospital admission. Nineteen of the 35 deaths occurred within three days of the hyperkalaemia being recorded. A normal plasma potassium was eventually documented in 50 of the 86 patients. Of the remaining 36 patients, 25 (69\%) subsequently died. In general the treatment of patients with hyperkalaemia focused on identifying and treating the underlying cause. Hyperkalaemia must always be considered seriously and regard given to the overall clinical status of the patient, with particular attention to drug therapy, renal and cardiac function, acid base status and the possibility of sepsis.}, language = {eng}, number = {878}, journal = {The New Zealand Medical Journal}, author = {Moore, M.
