A single-genome assembly program (assembler) is not capable of resolving metagenome sequences, so assemblers designed specifically for metagenomics have been developed. MetaVelvet is an extension of the single-genome assembler Velvet. It has been proved to generate assemblies with higher N50 scores and higher quality than single-genome assemblers such as Velvet and SOAPdenovo when applied to metagenomic sequence reads and is frequently used in this research community. One important open problem for MetaVelvet is its low accuracy and sensitivity in detecting chimeric nodes in the assembly (de Bruijn) graph, which prevents the generation of longer contigs and scaffolds. We have tackled this problem of classifying chimeric nodes using supervised machine learning to significantly improve the performance of MetaVelvet and developed a new tool, called MetaVelvet-SL. A Support Vector Machine is used for learning the classification model based on 94 features extracted from candidate nodes. In extensive experiments, MetaVelvet-SL outperformed the original MetaVelvet and other state-of-the-art metagenomic assemblers, IDBA-UD, Ray Meta and Omega, to reconstruct accurate longer assemblies with higher N50 scores for both simulated data sets and real data sets of human gut microbial sequences.}, language = {eng}, number = {1}, journal = {DNA research: an international journal for rapid publication of reports on genes and genomes}, author = {Afiahayati, null and Sato, Kengo and Sakakibara, Yasubumi}, month = feb, year = {2015}, pmid = {25431440}, pmcid = {PMC4379979}, keywords = {Genome, Humans, Metagenome, Metagenomic, Sequence Analysis, DNA, Software, Support Vector Machine, de novo assembler, microbial community, short read, supervised learning}, pages = {69--77} }

Biological and technical heterogeneity in proteomic experiments further add to the challenge and there are strong differences in opinion regarding the conceptual validity of a protein FDR and no consensus regarding the methodology for protein FDR determination. There are also limitations inherent to the widely used classic target-decoy strategy that particularly show when analyzing very large data sets and that lead to a strong over-representation of decoy identifications. In this study, we investigated the merits of the classic, as well as a novel target-decoy-based protein FDR estimation approach, taking advantage of a heterogeneous data collection comprised of ∼19,000 LC-MS/MS runs deposited in ProteomicsDB (https://www.proteomicsdb.org). The "picked" protein FDR approach treats target and decoy sequences of the same protein as a pair rather than as individual entities and chooses either the target or the decoy sequence depending on which receives the highest score. We investigated the performance of this approach in combination with q-value based peptide scoring to normalize sample-, instrument-, and search engine-specific differences. The "picked" target-decoy strategy performed best when protein scoring was based on the best peptide q-value for each protein yielding a stable number of true positive protein identifications over a wide range of q-value thresholds. We show that this simple and unbiased strategy eliminates a conceptual issue in the commonly used "classic" protein FDR approach that causes overprediction of false-positive protein identification in large data sets. The approach scales from small to very large data sets without losing performance, consistently increases the number of true-positive protein identifications and is readily implemented in proteomics analysis software.}, language = {eng}, number = {9}, journal = {Molecular \& cellular proteomics: MCP}, author = {Savitski, Mikhail M. and Wilhelm, Mathias and Hahne, Hannes and Kuster, Bernhard and Bantscheff, Marcus}, month = sep, year = {2015}, pmid = {25987413}, pmcid = {PMC4563723}, keywords = {Chromatography, Liquid, Databases, Protein, False Positive Reactions, Humans, Proteomics, Reproducibility of Results, Software, Tandem Mass Spectrometry}, pages = {2394--2404} }

Prior studies have noted immunohistochemical and biological characteristics shared by IHs and placental tissue. OBJECTIVES: We investigated the possible association between placental anomalies and the development of IHs, as well as the demographic characteristics and other risk factors for IHs. PATIENTS AND METHODS: Pregnant women (n = 578) were prospectively enrolled and their offspring followed for 9 months. Placental evaluations were performed and demographic data collected on all mother-infant pairs. RESULTS: We evaluated 594 infants: 34 haemangiomas [either IH or congenital (CH)] were identified in 29 infants, yielding an incidence of 4·5\% for IH (27 infants) and 0·3\% for CH (two infants). Placental anomalies were noted in almost 35\% of haemangioma-related pregnancies, approximately twice the incidence noted in pregnancies with unaffected infants (P = 0·025). Other risk factors for IH included prematurity (P = 0·016) and low birth weight (P = 0·028). All IHs were present by 3 months of age, and cessation of growth had occurred in all by 9 months of age. Most occurred on the trunk. Of note, 20\% of identified IHs were abortive or telangiectatic in nature, small focal lesions that did not proliferate beyond 3 months of age. Only one IH required intervention. CONCLUSIONS: This is the first prospective American study to document the incidence of IHs in infants followed from birth to early infancy. The association with placental anomalies was statistically significant.

SETTING: Prospective open cohort study using practices contributing to the CPRD database and practices contributing to the QResearch database. PARTICIPANTS: The CPRD validation cohort consisted of 3.3 million patients, aged 25-99 years registered at 357 general practices between 1 Jan 1998 and 31 July 2012. The validation statistics for QResearch were obtained from the original published papers which used a one-third sample of practices separate to those used to derive the score. A cohort from QResearch was used to compare incidence rates and baseline characteristics and consisted of 6.8 million patients from 753 practices registered between 1 Jan 1998 and until 31 July 2013. OUTCOME MEASURES: Incident events relating to seven different risk prediction scores: QRISK2 (cardiovascular disease); QStroke (ischaemic stroke); QDiabetes (type 2 diabetes); QFracture (osteoporotic fracture and hip fracture); QKidney (moderate and severe kidney failure); QThrombosis (venous thromboembolism); QBleed (intracranial bleed and upper gastrointestinal haemorrhage). Measures of discrimination and calibration were calculated. RESULTS: Overall, the baseline characteristics of the CPRD and QResearch cohorts were similar though QResearch had higher recording levels for ethnicity and family history. The validation statistics for each of the risk prediction scores were very similar in the CPRD cohort compared with the published results from QResearch validation cohorts. For example, in women, the QDiabetes algorithm explained 50\% of the variation within CPRD compared with 51\% on QResearch and the receiver operator curve value was 0.85 on both databases. The scores were well calibrated in CPRD. CONCLUSIONS: Each of the algorithms performed practically as well in the external independent CPRD validation cohorts as they had in the original published QResearch validation cohorts.}, language = {eng}, number = {8}, journal = {BMJ open}, author = {Hippisley-Cox, Julia and Coupland, Carol and Brindle, Peter}, year = {2014}, pmid = {25168040}, pmcid = {PMC4156807}, keywords = {Adult, Aged, Aged, 80 and over, Algorithms, Calibration, Cardiovascular Diseases, Cprd, Ethnic Groups, Family, Female, General Practice, Hemorrhage, Humans, Kidney Diseases, Male, Middle Aged, Osteoporotic Fractures, Prognosis, Prospective Studies, QResearch, Qrisk2, Risk, Validation, Venous Thromboembolism, diabetes mellitus}, pages = {e005809} }

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

However, recent falls in cardiovascular disease rates and more active management of risk factors may have abolished the increased risk. We aimed to provide an up-to-date assessment of the relative risks associated with type 2 diabetes of all-cause and cardiovascular mortality in middle-aged people in the U.K. RESEARCH DESIGN AND METHODS: Using data from the General Practice Research Database, from 2004 to 2010, we conducted a cohort study of 87,098 people, 40-65 years of age at baseline, comparing 21,798 with type 2 diabetes and 65,300 without diabetes, matched on age, sex, and general practice. We produced hazard ratios (HRs) for mortality and compared rates of blood pressure testing, cholesterol monitoring, and use of aspirin, statins, and antihypertensive drugs. RESULTS People with type 2 diabetes, compared with people without diabetes, had a twofold increased risk of all-cause mortality (HR 2.07 [95\% CI 1.95-2.20], adjusted for smoking) and a threefold increased risk of cardiovascular mortality (3.25 [2.87-3.68], adjusted for smoking).

However, challenges in such estimation include: (1) potential cases are not usually virologically tested; (2) cases have non-specific symptoms and are rarely reported to surveillance systems; (3) endpoints for influenza proxies (such as influenza-like illness) need to be matched to case definitions for treatment costs, (4) disease burden estimates vary from year to year with strain transmissibility, virulence and prior immunity, (5) methods to estimate productivity losses due to influenza vary, (6) vaccine efficacy estimates from trials differ due to variation in subtype prevalence, vaccine match and case ascertainment, and (7) indirect (herd) protection from vaccination depends on setting-specific variables that are difficult to directly measure.

In the first, participants completed visuospatial 0-back and 2-back tasks during the encoding of information to be remembered. The concurrent tasks did not differentially disrupt performance on backward digit recall, relative to forward digit recall. Experiment 2 shifted concurrent load to the recall phase instead and, in this case, revealed a larger effect of both tasks on backward recall, relative to forwards recall, suggesting that backward recall may draw on additional resources during the recall phase and that these resources are visuospatial in nature. Experiments 3 and 4 then further investigated the role of visual processes in forward and backward recall using dynamic visual noise (DVN). In Experiment 3, DVN was presented during encoding of information to be remembered and had no effect upon performance. However, in Experiment 4, it was presented during the recall phase, and the results provided evidence of a role for visual imagery in backward digit recall.

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

In the case of mass cytometry, the signal variation over time due to changes in instrument performance combined with intervals between scheduled maintenance must be accounted for and then normalized. Here, samples were mixed with polystyrene beads embedded with metal lanthanides, allowing monitoring of mass cytometry instrument performance over multiple days of data acquisition. The protocol described here includes simultaneous measurements of beads and cells on the mass cytometer, subsequent extraction of the bead-based signature, and the application of an algorithm enabling correction of both short- and long-term signal fluctuations. The variation in the intensity of the beads that remains after normalization may also be used to determine data quality. Application of the algorithm to a one-month longitudinal analysis of a human peripheral blood sample reduced the range of median signal fluctuation from 4.9-fold to 1.3-fold.}, language = {eng}, number = {5}, journal = {Cytometry.

Thirty predictors were identified using a genetic algorithm on a training set (n=1500) and validated with a logistic regression model on an independent validation set (n=613). The final prediction algorithm used included dynamic information and had good discrimination (area under the receiver operating curve=82.0%) and calibration (Hosmer-Lemeshow C statistic=10.43, p=0.06). This model was compared with Acute Physiology and Chronic Health Evaluation IV using reclassification indices and was found to be superior with an Net Reclassification Improvement of 0.19 (p<0.001) and an Integrated Discrimination Improvement of 0.09 (p<0.001).\n\nCONCLUSIONS: Hospital mortality predictions based on dynamic variables surrounding a hypotensive event is a new approach to predicting prognosis.

Image-based meta-analyses use full image information (i.e. the statistical parametric maps) and well-established statistics, but images are rarely available making them highly unfeasible. Peak-probability meta-analyses such as activation likelihood estimation (ALE) or multilevel kernel density analysis (MKDA) are more feasible as they only need reported peak coordinates. Signed-differences methods, such as signed differential mapping (SDM) build upon the positive features of existing peak-probability methods and enable meta-analyses of studies comparing patients with controls. In this paper we present a new version of SDM, named Effect Size SDM (ES-SDM), which enables the combination of statistical parametric maps and peak coordinates and uses well-established statistics. We validated the new method by comparing the results of an ES-SDM meta-analysis of studies on the brain response to fearful faces with the results of a pooled analysis of the original individual data. The results showed that ES-SDM is a valid and reliable coordinate-based method, whose performance might be additionally increased by including statistical parametric maps.

Objective segment classification as normal or abnormal was achieved by comparison to prediction intervals of FA and mean diffusivity (MD) defined in normal subjects. The internal capsules of each patient were segmented into 10 regions of interest (ROI) with 20 and 16 segments across the group having significantly increased or decreased FA and MD values respectively. Seven glioma patients had abnormal DTI parameters in the internal capsule. We show that the classification of tract segments was consistent with disruption, oedema or compression.

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.

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.

@article{kelly_london_2011, title = {The {London} low emission zone baseline study}, issn = {1041-5505}, abstract = {On February 4, 2008, the world's largest low emission zone (LEZ) was established. At 2644 km2, the zone encompasses most of Greater London. It restricts the entry of the oldest and most polluting diesel vehicles, including heavy-goods vehicles (haulage trucks), buses and coaches, larger vans, and minibuses. It does not apply to cars or motorcycles. The LEZ scheme will introduce increasingly stringent Euro emissions standards over time. The creation of this zone presented a unique opportunity to estimate the effects of a stepwise reduction in vehicle emissions on air quality and health. Before undertaking such an investigation, robust baseline data were gathered on air quality and the oxidative activity and metal content of particulate matter (PM) from air pollution monitors located in Greater London. In addition, methods were developed for using databases of electronic primary-care records in order to evaluate the zone's health effects. Our study began in 2007, using information about the planned restrictions in an agreed-upon LEZ scenario and year-on-year changes in the vehicle fleet in models to predict air pollution concentrations in London for the years 2005, 2008, and 2010. Based on this detailed emissions and air pollution modeling, the areas in London were then identified that were expected to show the greatest changes in air pollution concentrations and population exposures after the implementation of the LEZ. Using these predictions, the best placement of a pollution monitoring network was determined and the feasibility of evaluating the health effects using electronic primary-care records was assessed. To measure baseline pollutant concentrations before the implementation of the LEZ, a comprehensive monitoring network was established close to major roadways and intersections. Output-difference plots from statistical modeling for 2010 indicated seven key areas likely to experience the greatest change in concentrations of nitrogen dioxide (NO2) (at least 3 microg/m3) and of PM with an aerodynamic diameter {\textless} or = 10 microm (PM10) (at least 0.75 microg/m3) as a result of the LEZ; these suggested that the clearest signals of change were most likely to be measured near roadsides. The seven key areas were also likely to be of importance in carrying out a study to assess the health outcomes of an air quality intervention like the LEZ. Of the seven key areas, two already had monitoring sites with a full complement of equipment, four had monitoring sites that required upgrades of existing equipment, and one required a completely new installation. With the upgrades and new installations in place, fully ratified (verified) pollutant data (for PM10, PM with an aerodynamic diameter {\textless} or = 2.5 microm [PM2.5], nitrogen oxides [NOx], and ozone [O3] at all sites as well as for particle number, black smoke [BS], carbon monoxide [CO], and sulfur dioxide [SO2] at selected sites) were then collected for analysis. In addition, the seven key monitoring sites were supported by other sites in the London Air Quality Network (LAQN). From these, a robust set of baseline air quality data was produced. Data from automatic and manual traffic counters as well as automatic license-plate recognition cameras were used to compile detailed vehicle profiles. This enabled us to establish more precise associations between ambient pollutant concentrations and vehicle emissions. An additional goal of the study was to collect baseline PM data in order to test the hypothesis that changes in traffic densities and vehicle mixes caused by the LEZ would affect the oxidative potential and metal content of ambient PM10 and PM2.5. The resulting baseline PM data set was the first to describe, in detail, the oxidative potential and metal content of the PM10 and PM2.5 of a major city's airshed. PM in London has considerable oxidative potential; clear differences in this measure were found from site to site, with evidence that the oxidative potential of both PM10 and PM2.5 at roadside monitoring sites was higher than at urban background locations. In the PM10 samples this increased oxidative activity appeared to be associated with increased concentrations of copper (Cu), barium (Ba), and bathophenanthroline disulfonate-mobilized iron (BPS Fe) in the roadside samples. In the PM2.5 samples, no simple association could be seen, suggesting that other unmeasured components were driving the increased oxidative potential in this fraction of the roadside samples. These data suggest that two components were contributing to the oxidative potential of roadside PM, namely Cu and BPS Fe in the coarse fraction of PM (PM with an aerodynamic diameter of 2.5 microm to 10 microm; PM(2.5-10)) and an unidentified redox catalyst in PM2.5. The data derived for this baseline study confirmed key observations from a more limited spatial mapping exercise published in our earlier HEI report on the introduction of the London's Congestion Charging Scheme (CCS) in 2003 (Kelly et al. 2011a,b). In addition, the data set in the current report provided robust baseline information on the oxidative potential and metal content of PM found in the London airshed in the period before implementation of the LEZ; the finding that a proportion of the oxidative potential appears in the PM coarse mode and is apparently related to brake wear raises important issues regarding the nature of traffic management schemes. The final goal of this baseline study was to establish the feasibility, in ethical and operational terms, of using the U.K.'s electronic primary-care records to evaluate the effects of the LEZ on human health outcomes. Data on consultations and prescriptions were compiled from a pilot group of general practices (13 distributed across London, with 100,000 patients; 29 situated in the inner London Borough of Lambeth, with 200,000 patients). Ethics approvals were obtained to link individual primary-care records to modeled NOx concentrations by means of post-codes. (To preserve anonymity, the postcodes were removed before delivery to the research team.) A wide range of NOx exposures was found across London as well as within and between the practices examined. Although we observed little association between NOx exposure and smoking status, a positive relationship was found between exposure and increased socioeconomic deprivation. The health outcomes we chose to study were asthma, chronic obstructive pulmonary disease, wheeze, hay fever, upper and lower respiratory tract infections, ischemic heart disease, heart failure, and atrial fibrillation. These outcomes were measured as prevalence or incidence. Their distributions by age, sex, socioeconomic deprivation, ethnicity, and smoking were found to accord with those reported in the epidemiology literature. No cross-sectional positive associations were found between exposure to NOx and any of the studied health outcomes; some associations were significantly negative. After the pilot study, a suitable primary-care database of London patients was identified, the General Practice Research Database responsible for giving us access to these data agreed to collaborate in the evaluation of the LEZ, and an acceptable method of ensuring privacy of the records was agreed upon. The database included about 350,000 patients who had remained at the same address over the four-year period of the study. Power calculations for a controlled longitudinal analysis were then performed, indicating that for outcomes such as consultations for respiratory illnesses or prescriptions for asthma there was sufficient power to identify a 5\% to 10\% reduction in consultations for patients most exposed to the intervention compared with patients presumed to not be exposed to it. In conclusion, the work undertaken in this study provides a good foundation for future LEZ evaluations. Our extensive monitoring network, measuring a comprehensive set of pollutants (and a range of particle metrics), will continue to provide a valuable tool both for assessing the impact of LEZ regulations on air quality in London and for furthering understanding of the link between PM's composition and toxicity. Finally, we believe that in combination with our modeling of the predicted population-based changes in pollution exposure in London, the use of primary-care databases forms a sound basis and has sufficient statistical power for the evaluation of the potential impact of the LEZ on human health.}, language = {eng}, number = {163}, journal = {Research Report (Health Effects Institute)}, author = {Kelly, Frank and Armstrong, Ben and Atkinson, Richard and Anderson, H.

However, the geographic source and origins of this epidemic remain unclear. METHODS: Here we used phylogenetic inference and "relaxed" molecular clock dating analysis to further characterize the Romanian HIV-1 subtype F epidemic. RESULTS: These analyses revealed a major lineage of Romanian HIV sequences consisting nearly entirely of virus sampled from adolescents and children and a distinct cluster that included a much higher ratio of adult sequences. Divergence time estimates inferred the time of most recent common ancestor of subtype F1 sequences to be 1973 (1966-1980) and for all Angolan sequences to 1975 (1968-1980). The most common ancestor of the Romanian sequences was dated to 1978 (1972-1983) with pediatric and adolescent sequences interspersed throughout the lineage. The phylogenetic structure of the entire subtype F epidemic suggests that multiple introductions of subtype F into Romania occurred either from the Angolan epidemic or from more distant ancestors. Since the historical records note that the Romanian pediatric epidemic did not begin until the late 1980s, the inferred time of most recent common ancestor of the Romanian lineage of 1978 suggests that there were multiple introductions of subtype F occurred into the pediatric population from HIV already circulating in Romania.

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

However, few reports exist of successful research utilization in nursing interventions. Systematic identification and evaluation of individual characteristics associated with and predicting research utilization may inform the development of research utilization interventions. OBJECTIVE: To update the evidence published in a previous systematic review on individual characteristics influencing research utilization by nurses. METHODS: As part of a larger systematic review on research utilization instruments, 12 online bibliographic databases were searched. Hand searching of specialized journals and an ancestry search was also conducted. Randomized controlled trials, clinical trials, and observational study designs examining the association between individual characteristics and nurses' use of research were eligible for inclusion. Studies were limited to those published in the English, Danish, Swedish, and Norwegian languages. A vote counting approach to data synthesis was taken. RESULTS: A total of 42,770 titles were identified, of which 501 were retrieved. Of these 501 articles, 45 satisfied our inclusion criteria. Articles assessed research utilization in general (n = 39) or kinds of research utilization (n = 6) using self-report survey measures. Individual nurse characteristics were classified according to six categories: beliefs and attitudes, involvement in research activities, information seeking, education, professional characteristics, and socio-demographic/socio-economic characteristics. A seventh category, critical thinking, emerged in studies examining kinds of research utilization. Positive relationships, at statistically significant levels, for general research utilization were found in four categories: beliefs and attitudes, information seeking, education, and professional characteristics. The only characteristic assessed in a sufficient number of studies and with consistent findings for the kinds of research utilization was attitude towards research; this characteristic had a positive association with instrumental and overall research utilization. CONCLUSIONS: This review reinforced conclusions in the previous review with respect to positive relationships between general research utilization and: beliefs and attitudes, and current role. Furthermore, attending conferences/in-services, having a graduate degree in nursing, working in a specialty area, and job satisfaction were also identified as individual characteristics important to research utilization. While these findings hold promise as potential targets of future research utilization interventions, there were methodological problems inherent in many of the studies that necessitate their findings be replicated in further research using more robust study designs and multivariate assessment methods.}, bibtype = {article}, author = {Squires, Janet E and Estabrooks, Carole A and Gustavsson, Petter and Wallin, Lars}, journal = {Implementation Science} }

Despite the wealth of data available in neuroscience, our understanding of this system is still very limited. Here we argue that an essential component in our arsenal of methods to advance our understanding of the brain is the construction of artificial brain-like systems. In this way we can encompass the multi-level organisation of the brain and its role in the context of the complete embodied real-world and real-time perceiving and behaving system. Hence, on the one hand, we must be able to develop and validate theories of brains as closing the loop between perception and action, and on the other hand as interacting with the real world. Evidence is growing that one of the sources of the computational power of neuronal systems lies in the massive and specific connectivity, rather than the complexity of single elements. To meet these challenges-multiple levels of organisation, sophisticated connectivity, and the interaction of neuronal models with the real-world-we have developed a multi-level neuronal simulation environment, iqr. This framework deals with these requirements by directly transforming them into the core elements of the simulation environment itself. iqr provides a means to design complex neuronal models graphically, and to visualise and analyse their properties on-line. In iqr connectivity is defined in a flexible, yet compact way, and simulations run at a high speed, which allows the control of real-world devices-robots in the broader sense-in real-time. The architecture of iqr is modular, providing the possibility to write new neuron, and synapse types, and custom interfaces to other hardware systems. The code of iqr is publicly accessible under the GNU General Public License (GPL). iqr has been in use since 1996 and has been the core tool for a large number of studies ranging from detailed models of neuronal systems like the cerebral cortex, and the cerebellum, to robot based models of perception, cognition and action to large-scale real-world systems. In addition, iqr has been widely used over many years to introduce students to neuronal simulation and neuromorphic control. In this paper we outline the conceptual and methodological background of iqr and its design philosophy. Thereafter we present iqr's main features and computational properties. Finally, we describe a number of projects using iqr, singling out how iqr is used for building a "synthetic insect".}, bibtype = {article}, author = {Bernardet, Ulysses and Verschure, Paul F.M.J.}, journal = {Neuroinformatics}, number = {2} }

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

In the current study, we measured EEG during a TNT task and performed ERP and EEG spectral power band analyses. ERP results replicated other researchers' observations of increases in 500-800 msec parietal effects for items where retrieval was instructed to be elaborated compared with being suppressed. Furthermore, EEG analyses indicated increased alpha (8-12 Hz) and theta (3-8 Hz) oscillations across parietal electrodes for items that were instructed to be suppressed versus those to be elaborated. Additionally, during the second half of the experiment (after repeated attempts at control), increases in theta oscillations were found across both frontal and parietal electrodes for items that were instructed to be suppressed and that were ultimately forgotten versus those ultimately remembered. Increased alpha power for items that were instructed to be suppressed versus elaborated may indicate reductions of retrieval attempts or lack of retrieval success. Increased theta power for items that were instructed to be suppressed versus elaborated may indicate increased or prolonged cognitive control to monitor retrieval events.}, bibtype = {article}, author = {Depue, Brendan Eliot and Ketz, Nick and Mollison, Matthew V and Nyhus, Erika and Banich, Marie T and Curran, Tim}, journal = {Journal of Cognitive Neuroscience}, number = {10} }

DESIGN: Prospective open cohort study using routinely collected data from 368 QResearch general practices in England and Wales to develop the scores. The scores were validated using two separate sets of practices-188 separate QResearch practices and 364 practices contributing to the THIN database. SUBJECTS: In the QResearch derivation cohort 225 922 new users of statins and 1 778 770 non-users of statins were studied. In the QResearch validation cohort 118 372 statin users and 877 812 non-users of statins were studied. In the THIN validation cohort, we studied 282 056 statin users and 1 923 840 non-users of statins were studied. METHODS: Cox proportional hazards models in the derivation cohort to derive risk equations. Measures of calibration and discrimination in both validation cohorts. OUTCOMES: 5-Year risk of moderate/serious myopathic events; moderate/serious liver dysfunction; acute renal failure and cataract. RESULTS: The performance of three of the risk prediction algorithms in the THIN cohort was very good. For example, in women, the algorithm for moderate/serious myopathy explained 42.15\% of the variation. The corresponding D statistics was 1.75. The acute renal failure algorithm explained 59.62\% of the variation (D statistic=2.49). The cataract algorithm explained 59.14\% of the variation (D statistic=2.46). The algorithms to predict moderate/severe liver dysfunction only explained 15.55\% of the variation (D statistics=0.89). The performance of each algorithm was similar for both sexes when tested on the QResearch validation cohort.

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

Using a three-dimensional vectorcardiogram (VCG) formulation, we generate the normal cardiac dipole for a patient using a sum of Gaussian kernels, fitted to real VCG recordings. Abnormal beats are specified either as perturbations to the normal dipole or as new dipole trajectories. Switching between normal and abnormal beat types is achieved using a first-order Markov chain. Probability transitions can be learned from real data or modeled by coupling to heart rate and sympathovagal balance. Natural morphology changes from beat-to-beat are incorporated by varying the angular frequency of the dipole as a function of the inter-beat (RR) interval. The RR interval time series is generated using our previously described model whereby time- and frequency-domain heart rate (HR) and heart rate variability characteristics can be specified. QT-HR hysteresis is simulated by coupling the Gaussian kernels associated with the T-wave in the model with a nonlinear factor related to the local HR (determined from the last n RR intervals). Morphology changes due to respiration are simulated by introducing a rotation matrix couple to the respiratory frequency. We demonstrate an example of the use of this model by simulating HR-dependent T-wave alternans (TWA) with and without phase-switching due to ectopy.

However, the resolution of multiple exponential fluorescence decays has remained beyond the reach of most practical FD-FLIM systems. In this paper we describe the implementation of FD-FLIM using a 40MHz pulse train derived from a supercontinuum source for excitation. The technique, which we term multi-harmonic FLIM (mhFLIM), makes it possible to accurately resolve biexponential decays of fluorophores without any a priori information. The system's performance is demonstrated using a mixture of spectrally similar dyes of known composition and also on a multiply-labeled biological sample. The results are compared to those obtained from time correlated single photon counting (TCSPC) microscopy and a good level of agreement is achieved. We also demonstrate the first practical application of an algorithm derived by G. Weber [1] for analysing mhFLIM data. Because it does not require nonlinear minimisation, it offers potential for realtime analysis during acquisition.

Assessing care by using quality indicators could help decrease this variability. The objectives of this study were to formally develop valid quality indicators for melanoma and to assess hospital-level adherence with these measures in the United States. METHODS: Quality indicators were identified from available literature, consensus guidelines, and melanoma experts. Thirteen experts ranked potential measures for validity on the basis of the RAND/University of California, Los Angeles Appropriateness Methodology. Adherence with individual valid indicators and a composite measure of all indicators were assessed at 1,249 Commission on Cancer hospitals by using the National Cancer Data Base (NCDB; 2004 through 2005). RESULTS: Of 55 proposed quality indicators, 26 measures (47\%) were rated as valid. These indicators assessed structure (n = 1), process (n = 24), and outcome (n = 1). Of the 26 measures, 10 are readily assessable by using cancer registry data. Adherence with valid indicators ranged from 11.8\% to 96.5\% at the patient level and 3.7\% to 83.0\% at the hospital level. (Adherence required that {\textgreater}OR= 90\% of patients at a hospital receive concordant care.) Most hospitals were adherent with 50\% or fewer of the individual indicators (median composite score, five; interquartile range, four to seven). Adherence was higher for diagnosis and staging measures and was lower for treatment indicators. CONCLUSION: There is considerable variation in the quality of melanoma care in the United States. By using these formally developed quality indicators, hospitals can assess their adherence with current melanoma care guidelines through feedback mechanisms from the NCDB and can better direct quality improvement efforts.}, language = {eng}, number = {32}, journal = {Journal of Clinical Oncology: Official Journal of the American Society of Clinical Oncology}, author = {Bilimoria, Karl Y. and Raval, Mehul V. and Bentrem, David J. and Wayne, Jeffrey D. and Balch, Charles M. and Ko, Clifford Y.}, month = nov, year = {2009}, pmid = {19826131}, keywords = {Databases, Factual, Delivery of Health Care, Humans, Melanoma, Outcome Assessment (Health Care), Quality Indicators, Health Care, United States}, pages = {5445--5451} }

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

A better understanding of the mechanisms of disease protection could allow novel strategies to disease management and control. OBJECTIVES: To identify human genomic loci with evidence of linkage to tuberculosis susceptibility and, within these loci, to identify individual genes influencing tuberculosis susceptibility. METHODS: Affected sibling pair analysis in South African and Malawian populations. Independent case-control study in West Africa. MEASUREMENTS AND MAIN RESULTS: Two novel putative loci for tuberculosis susceptibility are identified: chromosome 6p21-q23 and chromosome 20q13.31-33--the latter with the strongest evidence for any locus reported to date in human tuberculosis (single point LOD score of 3.1, P = 10(-4), with a maximum likelihood score [MLS] of 2.8). An independent, multistage genetic association study in West African populations mapped this latter region in detail, finding evidence that variation in the melanocortin 3 receptor (MC3R) and cathepsin Z (CTSZ) genes play a role in the pathogenesis of tuberculosis.

We compared the relative sensitivity of these distinct cell types to clinical antimyeloma agents and found that dexamethasone, lenadilomide, bortezomib, and 4-hydroxycyclophosphamide inhibited CD138(+) multiple myeloma plasma cells but had little effect on CD138(neg) precursors in vitro. We further characterized clonogenic multiple myeloma cells and stained cell lines using the Hoechst side population and Aldefluor assays.

We also found that multiple myeloma cells expressing the memory B-cell markers CD20 and CD27 could give rise to clonogenic multiple myeloma growth in vitro and engraft immunodeficient nonobese diabetes/severe combined immunodeficient mice during both primary and secondary transplantation. Furthermore, both the side population and Aldefluor assays were capable of identifying circulating clonotypic memory B-cell populations within the peripheral blood of multiple myeloma patients.

It has been suggested recently that PVRL2, not APOE, is the locus on chromosome 19 which influences clinical outcome of MS. A cohort of sporadic MS cases, taken from opposite extremes of the putative distribution of long-term outcome using the most stringent clinical criteria to date, was used to determine the role of APOE and PVRL2 on MS disease severity. The MS cases selected represent the prognostic best 5% (benign MS) and worst 5% (malignant MS) of cases in terms of clinical outcome assessed by the EDSS. Genotyping the two sets of MS patients (112 benign and 51 malignant) and a replication cohort from Sardinia provided no evidence to suggest that APOE or PVRL2 have any outcome modifying activity.

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

STUDY DESIGN: An observational retrospective database analysis was conducted using override reasons derived from a computerized system at 6 Veterans Affairs medical centers. METHODS: Data on DDI alerts (for interactions designated as "critical" and "significant") were obtained from ambulatory care pharmacy records from July 1, 2003, to June 30, 2004. Prescribers' reasons for overriding alerts were organized into 14 categories and were then rated as clinically useful or not to the pharmacist in the assessment of potential patient harm. RESULTS: Of 291,890 overrides identified, 72\% were for critical DDIs. Across the Veterans Affairs medical centers, only 20\% of the override reasons for critical DDI alerts were rated as clinically useful for order verification.

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.

The present paper deals with the contribution of neuropsychology to the characterization of the type of epilepsy and the possible mechanisms underlying idiopathic epileptic syndromes. The non-lesional, so-called idiopathic epilepsies, constitute an interesting model for assessing the relationship between epileptiform {EEG} discharges and cognition. Among the idiopathic generalized epilepsies, disorders of social integration and personality have been frequently reported in juvenile myoclonic epilepsy ({JME}). Since similar disturbances are observed in frontal-lobe-lesioned patients, impairments in other frontal lobe functions (e.g. executive functions) might be expected in {JME}. This gives rise to speculation about the possible underlying pathophysiological mechanisms in {JME}. With regard to partial idiopathic epilepsies, benign childhood epilepsy with centrotemporal spikes ({BCECTS}) may provide a useful model for the study of the relationship between epileptiform {EEG} discharges in the peri-sylvian region and language functions. Furthermore, the description of mild cognitive dysfunctions in {BCECTS}, and their persistence into adulthood, can provide information about compensatory mechanisms and may allow for the generation of remedial strategies. Thus, 'lesional' neuropsychology has given way to 'dynamic' neuropsychology based on specific postulates. By using the cognitive profile to specify the mechanism underlying the behavioral disturbances observed in different types of epilepsy, neuropsychology may eventually contribute to a revision of the present classification of epileptic syndromes. In addition, the neuropsychological data may help predict the extent and limits of functional recovery and cerebral plasticity.}, language = {eng}, number = {1}, journal = {Neuroscience and Biobehavioral Reviews}, author = {Hommet, Caroline and Sauerwein, Hannelore C. and De Toffol, Bertrand and Lassonde, Maryse}, year = {2006}, pmid = {16120462}, keywords = {Cognition Disorders, Electroencephalography, Epilepsy, Humans, Neuropsychology, Syndrome}, pages = {85--96} }

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.

Cyclophosphamide and cyclosporine are well-established alternative immunomodulating agents, whereas data on FK 506 (tacrolimus) are rare. METHODS: The present work provides data from 10 patients of an open, monocentric, non-randomized, prospective trial. Five patients with steroid-dependent minimal-change nephrotic syndrome, 1 patient with steroid-refractory minimal-change disease and 4 patients with steroid-refractory FSGS were started on tacrolimus at trough levels of 5 10 microg/l. In case of steroid-dependence, prednisolone was tapered off in presence oftacrolimus within one month. RESULTS: Within 6 months, complete remission was achieved in 5 patients (50\%) and partial remission in 4 patients (40\%), yielding a final response rate of 90\%. One patient was primarily resistent to tacrolimus (steroid-refractory minimal-change), another patient became secondarily resistant to tacrolimus after an initial remission (steroid-refractory FSGS). Average proteinuria significantly decreased by 77\% from 9.5 +/- 1.4 - 2.2 +/- 1.1 g/day (p {\textless} 0.01). Serum protein significantly raised from 55.0 +/- 1.9 - 64.6 +/- 1.9 g/l (p {\textless} 0.01).

Five patients have been tapered off tacrolimus so far, nephrotic syndrome relapsed in 4 of them (80\%). Relapse occurred at tacrolimus levels between 2.6 and 6.9 ng/ml.

The clinical pregnancy rate (PR) per cycle after controlled ovarian hyperstimulation (COH) with or without intrauterine insemination (IUI) is reportedly lower in women with surgically untreated minimal to mild endometriosis than in women with unexplained infertility. It is possible that prior laparoscopic removal of endometriosis has a positive effect on the clinical PR after COH and IUI. Therefore, we tested the hypothesis that after COH and IUI the PR per cycle and the cumulative live-birth rate (CLBR) are equal or higher in women with recently surgically treated minimal to mild endometriosis when compared with women with unexplained infertility. DESIGN: A retrospective, controlled cohort study. SETTING: Leuven University Fertility Centre, a tertiary academic referral center. PATIENT(S): One hundred seven women treated during 259 cycles with COH and IUI including patients with endometriosis (n = 58, 137 cycles) and unexplained infertility (n = 49, 122 cycles). All patients with endometriosis had minimal (n = 41, 100 cycles) or mild (n = 17, 37 cycles) disease that had been laparoscopically removed within 7 months before the onset of treatment with COH and IUI. INTERVENTION(S): Controlled ovarian hyperstimulation using clomiphene citrate (23 cycles) or gonadotrophins (236 cycles) in combination with IUI. MAIN OUTCOME MEASURE(S): Clinical PR per cycle and CLBR within four cycles of treatment with COH and IUI. RESULT(S): The clinical PR per cycle was comparable in women with minimal or mild endometriosis (21\% or 18.9\%, respectively) and in women with unexplained infertility (20.5\%). The CLBR within four cycles of COH and IUI was also comparable in women with minimal endometriosis, mild endometriosis, and unexplained infertility (70.2\%, 68.2 \%, 66.5\%, respectively). CONCLUSION(S): The data from our study suggest that COH and IUI shortly after laparoscopic excision of endometriosis is as effective as COH and IUI in patients with unexplained subfertility.}, language = {eng}, number = {3}, journal = {Fertility and Sterility}, author = {Werbrouck, Erika and Spiessens, Carl and Meuleman, Christel and D'Hooghe, Thomas}, month = sep, year = {2006}, pmid = {16952506}, keywords = {Adult, Comorbidity, Endometriosis, Female, Humans, Infertility, Insemination, Artificial, Laparoscopy, Live Birth, Menstrual Cycle, Ovulation Induction, Pregnancy, Pregnancy Rate, Prevalence, Prognosis, Retrospective Studies, Treatment Outcome}, pages = {566--571} }

We demonstrated that exceptional longevity and healthy aging in humans is an inherited phenotype across three generations. Moreover, we demonstrated that subjects with exceptional longevity and their offspring have significantly larger high-density lipoprotein (HDL) levels and particle sizes and low-density lipoprotein (LDL) levels that reflect on their health and cognitive function performance. This phenotype have led us to study candidate genes involved in lipoprotein metabolism, and to the implication of homozygosity for the 405 valine (V) allele of cholesteryl ester transfer protein (CETP). A markedly higher frequency of a functional CETP variant that led to increased particle sizes of HDL and LDL and thus a better health performance is the first example of a phenotype and an associated genotype in humans with exceptional longevity.

Here we show that recent common ancestors also emerge from two models incorporating substantial population substructure. One model, designed for simplicity and theoretical insight, yields explicit mathematical results through a probabilistic analysis. A more elaborate second model, designed to capture historical population dynamics in a more realistic way, is analysed computationally through Monte Carlo simulations. These analyses suggest that the genealogies of all living humans overlap in remarkable ways in the recent past.

In the first millenniums BC and AD, the Netherlands were invaded by Celts, Romans, Huns, and Germans. In more recent times, large numbers of Huguenots and Germans migrated into the Netherlands. Population growth within the Netherlands was slow until the 19th century, when a period of rapid population growth started. Today, the Dutch population numbers 16 million inhabitants. Several different classes of founder mutations have been identified among the Dutch. Some mutations occur among people who represent genetic isolates within this country. These include mutations for benign familial cholestasis, diabetes mellitus, type I, infantile neuronal ceroid lipofuscinosis, L-DOPA responsive dystonia, and triphalangeal thumb. Although not related to a specific isolate, other founder mutations were identified only within the Netherlands, including those predisposing for hereditary breast-ovarian cancer, familial hypercholesterolemia, frontotemporal dementia, hereditary paragangliomas, juvenile neuronal ceroid lipofuscinosis, malignant melanoma, protein C deficiency, and San Filippo disease. Many of these show a regional distribution, suggesting dissemination from a founder. Some mutations that occur among the Dutch are shared with other European populations and others have been transmitted by Dutch emigres to their descendents in North America and South Africa. The occurrence of short chromosomal regions that have remained identical by descent has resulted in relatively limited genetic heterogeneity for many genetic conditions among the Dutch. These observations demonstrate the opportunity for gene discovery for other diseases and traits in the Netherlands.}, bibtype = {article}, author = {Zeegers, M P and van Poppel, F and Vlietinck, R and Spruijt, L and Ostrer, H}, journal = {Eur J Hum Genet}, number = {7} }

Our analysis shows that 22\% (5880) of the human transcription clusters form SA pairs, higher than any previous estimates. Our orientation-specific RT-PCR results along with the comparison of experimental data from previous studies confirm that our SA data set is reliable. This study not only demonstrates that our criteria for the prediction of SA transcripts are efficient, but also provides additional convincing data to support the view that antisense transcription is quite pervasive in the human genome. In-depth analyses show that SA transcripts have some significant differences compared with other types of transcripts, with regard to chromosomal distribution and Gene Ontology-annotated categories of physiological roles, functions and spatial localizations of gene products.}, number = {16}, journal = {Nucleic acids research}, author = {Chen, Jianjun and Sun, Miao and Kent, W James and Huang, Xiaoqiu and Xie, Hanqing and Wang, Wenquan and Zhou, Guolin and Shi, Run Zhang and Rowley, Janet D}, month = jan, year = {2004}, pmid = {15356298}, keywords = {Antisense, Antisense: analysis, Antisense: chemistry, Antisense: genetics, Base Pairing, Chromosomes, Genetic, Genome, Human, Humans, Messenger, Messenger: chemistry, RNA, Reverse Transcriptase Polymerase Chain Reaction, Transcription}, pages = {4812--20} }

In this article we investigate whether there are measurable advantages to having an active free gaze, over a static gaze or tracking gaze, when steering along a winding path. We also examine patterns of free gaze behavior to determine preferred gaze strategies during active locomotion. Participants were asked to steer along a computer-simulated textured roadway with free gaze, fixed gaze, or gaze tracking the center of the roadway. Deviation of position from the center of the road was recorded along with their point of gaze. It was found that visually tracking the middle of the road produced smaller steering errors than for fixed gaze. Participants performed best at the steering task when allowed to sample naturally from the road ahead with free gaze. There was some variation in the gaze strategies used, but sampling was predominantly of areas proximal to the center of the road. These results diverge from traditional models of flow analysis.}, bibtype = {article}, author = {Wilkie, R. M. and Wann, J. P.}, journal = {Journal of vision}, number = {11} }

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

The application of quadrupole ion trap tandem mass spectrometry to the examination of PCBs is focused upon those PCB congeners that have the greatest toxicity. 39 congeners of the total of 209 PCB congeners have been identified as having the greatest toxicities. Chemical ionization has been used for the determination of co-eluting congeners #77 and #110 where the toxicity of the former is much greater than that of the latter.

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

To be effective the antibody must bind to the fibrin component of the clot. The ability of two antifibrin mabs (NIB 1H10 and NIB 12B3) to penetrate occlusive clots in vivo was investigated. Both mabs react with human fibrin but not with human fibrinogen nor with the fibrin or fibrinogen from the species used in this study. Two heterologous animal (sheep and rabbit) thrombus models were used. Clots in both cases were made within isolated vein segments using a mixture of human and native fibrinogen. The clots in sheep veins were observed radiographically and found to be occlusive for a mean of 4.2 +/- 2.2 days and thereafter appeared only partially occlusive. When targeted in their occlusive phase (131)I labelled mab accumulated in the clot reaching a maximum ratio of 1.82 +/- 0.42 when compared to counts in homologous sheep clots in the contralateral limb. It was confirmed in the rabbit jugular vein model that total occlusivity did not prevent antibody accumulation in the heterologous clot by injecting the fibrin specific mab 1H10 and examining the clot excised after 1, 6 and 24 h using immunofluorescence. In a further series of similar experiments (125)I labelled mab 1H10 was used and detected using autoradiography. Both sets of experiments indicated that penetration of occlusive clots by the antibody occurred and that considerable accumulation was present at 6 and 24 h. The results indicate that a circulating antibody can readily gain access to experimentally produced clots in occluded veins.}, bibtype = {article}, author = {McEvoy, F J and Edgell, T A and Webbon, P M and Gaffney, P J}, journal = {Thrombosis and haemostasis}, number = {6} }

Short GCG expansions in the poly(A) binding protein 2 (PABP2) gene were identified recently as the molecular basis for OPMD in French-Canadians. All French-Canadian cases of OPMD have been traced to a single founder couple [Bouchard, 1997: Neuromuscul Disord 7(Suppl):S5-S11]. Cultural links between French-Canadians and Cajuns suggest that this same founder couple may have transmitted the OPMD mutation to Cajuns as well. To determine if OPMD patients from Louisiana share a founder effect with French-Canadian families, we collected blood samples and muscle biopsies from several Cajuns with OPMD for mutation and linkage studies. We found a unique 'GCA GCG GCG' insertion mutation in Cajuns. Consistent with these sequence data, we identified a disease haplotype in our Cajun families that is different from the ancestral haplotype defined in French-Canadians. These data prove that different founders introduced the PABP2 mutation to Cajuns and French-Canadians and lend support to emerging genealogical data suggesting that French-Canadians and Cajuns represent distinct immigrant groups from France.}, bibtype = {article}, author = {Scacheri, P C and Garcia, C and Hébert, R and Hoffman, E P and Hebert, R}, journal = {Am J Med Genet}, number = {5} }

@article{otoole_measuring_1999, title = {Measuring and developing suturing technique with a virtual reality surgical simulator}, volume = {189}, issn = {1072-7515}, abstract = {BACKGROUND We have developed an interactive virtual reality (VR) surgical simulator for the training and assessment of suturing technique. The surgical simulator is comprised of surgical tools with force feedback, a 3-dimensional graphics visual display of the simulated surgical field, physics-based computer simulations of the tissues and tools, and software to measure and evaluate the trainee's performance. STUDY DESIGN This study uses the simulator to measure and compare the skills of 8 experienced vascular surgeons versus 12 medical students when performing a virtual reality suturing task. Eight parameters of the suturing task were measured: total tissue damage, accuracy of needle puncture, peak tissue tearing force, time to complete the task, damage to the surface of the tissue, angular error in needle technique, total distance traveled by the tool tip, and a measure of overall error. Three test conditions (dominant hand, nondominant hand, and 3-dimensional needle guide) were tested. Statistical significance was defined as a univariate two-sided p value {\textless} or = 0.05. RESULTS The surgeons' average performance was significantly better than the students' average performance for three of the measured parameters (total tissue damage, time to complete the task, and total distance traveled by the tool tip) for each of the test conditions. For the test condition most similar to surgery (using the dominant hand to suture) one additional parameter was also significantly different (the measure of overall error). The medical students showed improvements for 6 of the 7 parameters for which the users received feedback during the training process. The surgeons also had significant improvement for 4 of the 7 parameters. The students had a larger improvement than the surgeons for 6 of the parameters, but these differences were not statistically significant. CONCLUSIONS Data indicate differences between surgeon and nonsurgeon performance and in improvement in performance with training. One possible explanation for the superior performance of the surgeons is that their suturing skills applied well to the simulated suturing task.

In this clinical setting, sonography (US), CT or even air enema may be the first modality chosen to evaluate these children rather than the radionuclide Meckel scan (RNMS). PURPOSE: To assess the value of US, CT and air enema for detection of complicated MD. MATERIALS AND METHODS: Review of clinical, imaging, surgical and pathological findings in 64 children (55 males, 9 females) aged 4 days -14 years (mean = 3.7 years) with MD seen during an 8-year period, 1990-1997. RESULTS: (a) In 33 patients with rectal bleeding, MD was detected on RNMS in 32. Ten of these 32 had other imaging studies, all of which were negative. (b) The other 31 patients, with varied clinical presentations, did not undergo RNMS. In these 31 and the 1 with a negative RNMS, 14 (44 \%) had imaging features highly suggestive for the diagnosis of MD on US in all 14, on CT in 1, and on air enema in 3. The radiological spectrum of the inflamed, hemorrhagic MD is illustrated. CONCLUSION: The inflamed, hemorrhagic and the inverted, intussuscepted MD have a spectrum of features recognizable on US, CT and air enema. Some of these appearances are specific, others are not. Knowledge of and recognition of these features will facilitate detection of complicated MD in larger numbers of children presenting with symptoms other than the classic history of painless rectal bleeding and also in those with normal RNMS.}, language = {eng}, number = {12}, journal = {Pediatric Radiology}, author = {Daneman, A. and Lobo, E. and Alton, D.

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

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

Patients in Clinical Group I (localized disease, completely resected) were randomized to receive either vincristine, dactinomycin, and cyclophosphamide (VAC) or VAC + radiation. At 5 years, approximately 80\% of patients given either treatment were still disease-free and there was no significant difference between treatments in the overall percentages of patients surviving of 93\% and 81\%, respectively (P = 0.67). Patients in Clinical Group II (regional disease, grossly resected) were randomized to receive either vincristine and dactinomycin (VA) + radiation or VAC + radiation. At 5 years, 72\% and 65\% of the patients, respectively, were disease-free and there was no evidence of a difference between treatments (P = 0.46). The overall survival percentage at 5 years was approximately 72\% for both treatments. Patients in Clinical Groups III (gross residual disease after surgery) and IV (metastatic disease) were randomized to receive either "pulse" VAC + radiation or "pulse" VAC + Adriamycin (doxorubicin) + radiation. The complete remission (CR) rate was 69\% in Clinical Group III and 50\% in IV, with no statistically significant difference in CR rates between treatments in either group. Those who achieved a CR had a nearly 60\% chance of staying in remission for 5 years in Clinical Group III compared with approximately 30\% in Clinical Group IV. The overall survival percentage at 5 years was 52\% in Clinical Group III compared to 20\% in Clinical Group IV (P less than 0.0001). The 5-year survival percentage for the entire cohort of 686 patients was 55\%. Survival after relapse was poor, being 32\% at 1 year and 17\% at 2 years. The risk of distant metastasis was much greater than the risk of local recurrence within each clinical group, and there was no evidence of differing types of relapses between treatments. Primary tumors of the orbit and genitourinary tract carried the best prognosis, whereas tumors of the retroperitoneum had the worst prognosis. The authors conclude that for the therapeutic regimens evaluated there was no therapeutic advantage to including radiation in the treatment of Clinical Group I disease, or cyclophosphamide given as a daily low-dose oral regimen in the treatment of Clinical Group II disease or Adriamycin in the treatment of Clinical Groups III and IV diseases.}, language = {eng}, number = {2}, journal = {Cancer}, author = {Maurer, H.

There was only one experimental condition (intensity increments) in which monkey DLs (1.5-2.0 dB) overlapped those of humans (1.0-1.8 dB). For discrimination of both increments and decrements in frequency, monkey DLs (16-33 Hz) were approximately seven times larger than those of humans (2.4-4.8 Hz), and for discrimination of intensity decrements, monkey DLs (4.4-7.0 dB) were very unstable and larger than those of humans (1.0-1.8 dB). For intensity increment discrimination, humans and monkeys also exhibited similar DLs as SL was varied. However, for frequency increment discrimination, best DLs for humans occurred at a high (50 dB) SL, whereas best DLs for monkeys occurred at a moderate (30 dB) SL. Results are discussed in terms of various neural mechanisms that might be differentially engaged by humans and monkeys in performing these tasks; for example, different amounts of temporal versus rate coding in frequency discrimination, and different mechanisms for monitoring rate decreases in intensity discrimination. The implications of these data for using monkeys as models of human speech sound discrimination are also discussed.}, bibtype = {article}, author = {Sinnott, J. and Petersen, M. and Hopp, S.}, number = {6} }
