METHODS: We sequenced the genomes of six persons with autosomal dominant LOCA who were members of three French Canadian families and identified a candidate pathogenic repeat expansion. We then tested for association between the repeat expansion and disease in two independent case-control series - one French Canadian (66 patients and 209 controls) and the other German (228 patients and 199 controls). We also genotyped the repeat in 20 Australian and 31 Indian index patients. We assayed gene and protein expression in two postmortem cerebellum specimens and two induced pluripotent stem-cell (iPSC)-derived motor-neuron cell lines. RESULTS: In the six French Canadian patients, we identified a GAA repeat expansion deep in the first intron of FGF14, which encodes fibroblast growth factor 14. Cosegregation of the repeat expansion with disease in the families supported a pathogenic threshold of at least 250 GAA repeats ([GAA]{\textgreater}/=250). There was significant association between FGF14 (GAA){\textgreater}/=250 expansions and LOCA in the French Canadian series (odds ratio, 105.60; 95\% confidence interval [CI], 31.09 to 334.20; P{\textless}0.001) and in the German series (odds ratio, 8.76; 95\% CI, 3.45 to 20.84; P{\textless}0.001). The repeat expansion was present in 61\%, 18\%, 15\%, and 10\% of French Canadian, German, Australian, and Indian index patients, respectively. In total, we identified 128 patients with LOCA who carried an FGF14 (GAA){\textgreater}/=250 expansion. Postmortem cerebellum specimens and iPSC-derived motor neurons from patients showed reduced expression of FGF14 RNA and protein. CONCLUSIONS: A dominantly inherited deep intronic GAA repeat expansion in FGF14 was found to be associated with LOCA.

Further evidence is needed to understand the risk of transmission in childcare centres. To this end, we established the DISeases TrANsmission in ChildcarE (DISTANCE) study to understand the interaction among contact patterns, detection of respiratory viruses from environment samples and transmission of viral infections in childcare centres. METHODS AND ANALYSIS: The DISTANCE study is a prospective cohort study in multiple childcare centres of Jiangsu Province, China. Study subjects will be childcare attendees and teaching staff of different grades. A range of information will be collected from the study subjects and participating childcare centres, including attendance, contact behaviours (collected by onsite observers), respiratory viral infection (weekly respiratory throat swabs tested by multiplex PCR), presence of respiratory viruses on touch surfaces of childcare centres and weekly follow-up survey on respiratory symptoms and healthcare seeking among subjects tested positive for any respiratory viruses. Detection patterns of respiratory viruses from study subjects and environment samples, contact patterns, and transmission risk will be analysed by developing statistical and mathematical models as appropriate. The study has been initiated in September 2022 in 1 childcare centre in Wuxi City, with a total of 104 children and 12 teaching staff included in the cohort; data collection and follow-up is ongoing. One more childcare centre in Nanjing City (anticipated to include 100 children and 10 teaching staff) will start recruitment in 2023. ETHICS AND DISSEMINATION: The study has received ethics approval from Nanjing Medical University Ethics Committee (No. 2022-936) and ethics approval from Wuxi Center for Disease Control and Prevention Ethics Committee (No. 2022-011). We plan to disseminate the study findings mainly through publications in peer-reviewed journals and presentations in academic conferences.

To increase this knowledge, the Pan American Hereditary Ataxia Network (PAHAN) conducted an exploratory survey about care for hereditary ataxias in American continents and the Caribbean. A questionnaire was sent to health professionals about the hereditary ataxias identified; access to care; and local teaching and research. The number of ataxics under current care per 100,000 inhabitants was subtracted from the expected overall prevalence of 6/100,000, to estimate the prevalence of uncovered ataxic patients. Local Human Development Indexes (HDI) were used to measure socio-economic factors. Twenty-six sites participated. Twelve sites had very high, 13 had high, and one site had medium HDI. Participants reported on 2239 and 602 patients with spinocerebellar ataxias and recessive forms under current care. The number of patients under current care per inhabitants varied between 0.14 and 12/100,000. The estimated prevalence of uncovered ataxic patients was inversely proportional to HDIs (rho = 0.665, p = 0.003). Access to diagnosis, pre-symptomatic tests, and rehabilitation were associated with HDIs. More and better molecular diagnostic tools, protocols and guidelines, and professional training for ataxia care were the top priorities common to all respondents. Evidence of inequalities was confirmed. Lower HDIs were associated with high potential numbers of uncovered ataxic subjects, and with lack of molecular diagnosis, pre-symptomatic testing, and rehabilitation.

People with BPD experience high rates of crisis presentations and stigma when accessing health services. Educational interventions designed to modify health practitioners' attitudes and practice in treating people with BPD may assist in addressing this stigma. The current review aimed to identify and explore existing educational interventions designed to modify health practitioners' attitudes and practice in BPD; and determine what impact educational interventions have on improving health practitioners' responses towards people with BPD. METHODS: A comprehensive search of the literature was undertaken in MEDLINE, CINAHL, PsycINFO, Scopus, Cochrane Library, and JBI Evidence-Based databases (from inception to February 2022). Secondary sources of literature included grey literature searches and handsearching the references of included studies as part of the comprehensive search strategy. The eligibility criteria included peer-reviewed empirical studies examining BPD-related educational interventions aimed at modifying health practitioners' attitudes and practice in treating people with BPD. Quality appraisal of the included studies were completed using the Mixed Methods Appraisal Tool 2018 version (MMAT v.18) or the Joanna Briggs Institute (JBI) Checklist for Systematic Reviews and Research Syntheses Tool. Thematic Analysis informed data extraction, analysis, interpretation, and narrative synthesis of the data. RESULTS: A total of nine papers containing 991 participants across a diverse range of studies including, quantitative, qualitative, mixed methods, and a systematic review were included in this integrative review. Several BPD-related educational interventions designed to modify health practitioners' attitudes and practice in BPD exist. Findings suggest that training health practitioners in BPD-related educational interventions can enhance positive attitudes and change practice towards people with BPD; however, more high-quality studies are needed to confirm these conclusions. CONCLUSIONS: This review collated and summarized findings from studies examining the impact of BPD-related educational interventions on changing health practitioners' attitudes and practice in treating this population. Results from this review may help inform future research, policy, and practice in stigma-reduction strategies which would improve the delivery of responsive health services and care for people with BPD.

Synovial fluid samples were analyzed using state-of-the-art mass spectrometry with data-independent acquisition. The differential expression of the proteins detected was clustered and evaluated with data mining strategies and a multilevel model. Group-specific slopes of associations were estimated between expressions of each pair of identified proteins to assess the co-expression (i.e., interplay) between the proteins in each group. More proteins were increased in early-OA versus controls than late-stage OA versus controls. For most of these proteins, the fold changes between late-stage OA versus controls and early-stage OA versus controls were remarkably similar suggesting potential involvement in the OA process. Further, for the first time, this study illustrated distinct patterns in protein co-expression suggesting that the interplay between the protein machinery is increased in early-OA and lost in late-stage OA.

We aimed to critically appraise and synthesise published evidence on the risk factors for poor outcomes in hospitalised COVID-19 patients. Methods: We searched PubMed, medRxiv and the WHO COVID-19 literature database for studies that reported characteristics of COVID-19 patients who required hospitalisation. We included studies published between January and May 2020 that reported adjusted effect size of any demographic and/or clinical factors for any of the three poor outcomes: mortality, intensive care unit (ICU) admission, and invasive mechanical ventilation. We appraised the quality of the included studies using Joanna Briggs Institute appraisal tools and quantitatively synthesised the evidence through a series of random-effect meta-analyses. To aid data interpretation, we further developed an interpretation framework that indicated strength of the evidence, informed by both quantity and quality of the evidence. Results: We included a total of 40 studies in our review. Most of the included studies (29/40, 73\%) were assessed as "good quality", with assessment scores of 80 or more. We found that male sex (pooled odds ratio (OR) = 1.32 (95\% confidence interval (CI) = 1.18-1.48; 20 studies), older age (OR = 1.05, 95\% CI = 1.04-1.07, per one year of age increase; 10 studies), obesity (OR = 1.59, 95\% CI = 1.02-2.48; 4 studies), diabetes (OR = 1.25, 95\% CI = 1.11-1.40; 11 studies) and chronic kidney diseases (6 studies; OR = 1.57, 95\% CI = 1.27-1.93) were associated with increased risks for mortality with the greatest strength of evidence based on our interpretation framework. We did not find increased risk of mortality for several factors including chronic obstructive pulmonary diseases (5 studies), cancer (4 studies), or current smoker (5 studies); however, this does not indicate absence of risk due to limited data on each of these factors. Conclusion: Male sex, older age, obesity, diabetes and chronic kidney diseases are important risk factors of COVID-19 poor outcomes.

The authors conducted a randomized controlled telemedicine trial of CBT-guided self-help (CBT-GSH) assisted with a smartphone app, Noom Monitor, for binge eating with or without purging. They hypothesized that coach-delivered CBT-GSH telemedicine sessions plus Noom Monitor would yield greater reductions in symptoms of binge eating, purging, and eating disorders compared with standard care. METHODS: Fifty-two-week outcomes for CBT-GSH plus Noom Monitor (N=114) were compared with outcomes for standard care (N=111) among members of an integrated health care system in the Pacific Northwest. Patients in the health system who met inclusion criteria were ≥18 years old, had a body mass index ≥18.5, met criteria for DSM-5 binge eating disorder or bulimia nervosa, had 12 months of continuous health care enrollment in Kaiser Permanente Northwest, and had a personal smartphone. Participants received eight CBT-GSH telemedicine sessions over 12 weeks administered by health coaches, and outcomes were assessed at baseline and at weeks 4, 8, 12, 26, and 52. The use of available treatment offered within the Kaiser Permanente health care system was permitted for participants assigned to standard care. RESULTS: Participants who received CBT-GSH plus Noom Monitor reported significant reductions in objective binge-eating days (β=-0.66, 95\% CI=-1.06, -0.25; Cohen's d=-1.46, 95\% CI=-4.63, -1.09) and achieved higher rates of remission (56.7\% compared with 30\%; number needed to treat=3.74) at 52 weeks compared with participants in standard care, none of whom received any eating disorder treatment during the intervention period (baseline and weeks 1-12). Similar patterns emerged for compensatory behaviors (vomiting, use of laxatives, and excessive exercise; 76.3\% compared with 56.8\%; number needed to treat=5.11), eating disorder symptoms (body shape, weight, eating concerns, and dietary restraint), and clinical impairment (Cohen's d=-10.07, -2.15).

We compared corticolimbic functional and structural connectivity between OCD patients and healthy controls (HCs), and correlated this with the dispositional use of emotion regulation strategies and with OCD severity. OCD patients (n = 73) and HCs (n = 42) were assessed for suppression and reappraisal strategies using the Emotion Regulation Questionnaire (ERQ) and for OCD severity using the Yale-Brown Obsessive-Compulsive Scale. Resting-state functional magnetic resonance imaging (rs-fMRI) connectivity maps were generated using subject-specific left amygdala (LA) and right amygdala (RA) masks. We identified between-group differences in amygdala whole-brain connectivity, and evaluated the moderating effect of ERQ strategies. Significant regions and amygdala seeds were used as targets in probabilistic tractography analysis. Patients scored higher in suppression and lower in reappraisal. We observed higher rs-fMRI RA-right postcentral gyrus (PCG) connectivity in HC, and in patients this was correlated with symptom severity. Reappraisal scores were associated with higher negative LA-left insula connectivity in HC, and suppression scores were negatively associated with LA-precuneus and angular gyri connectivity in OCD. Structurally, patients showed higher mean diffusivity in tracts connecting the amygdala with the other targets. RA-PCG connectivity is diminished in patients, while disrupted emotion regulation is related to altered amygdala connectivity with the insula and posterior brain regions.

Materials and Methods In this HIPAA-compliant, institutional review board-approved retrospective cohort study, an institutional database was searched for abdominal and pelvic CT studies performed between June 2003 and December 2010 in women reported to have adnexal cysts. Adnexal cyst characterization was determined by prospective report description as well as image review by a research fellow and by a fellowship-trained abdominal radiologist for examinations with disagreement between the original report and the research fellow{\textquoteright}s assessment. Patients with known ovarian cysts or ovarian cancer at time of the index CT examination were excluded. Clinical outcome was assessed by using follow-up imaging studies, medical records, and the state cancer registry. Benign outcome was determined by benign findings at surgery, a decrease in size or resolution of a simple-appearing cyst at follow-up imaging, or stability of the cyst for at least 1 year. Descriptive statistics and 95\% confidence intervals (CIs) were calculated. Results Among 42 111 women who underwent abdominal and pelvic CT examinations in the study period, 2763 (6.6\%; 95\% CI: 6.3\%, 6.8\%) (mean age, 48.1 years {\textpm} 18.1; range, 15-102 years) had a newly detected finding of ovarian cyst described in the body or impression section of the report. Median cyst size was 3.1 cm (range, 0.8-20.0 cm). Eighteen (0.7\%; 95\% CI: 0.4\%, 1.0\%) of 2763 patients were found to have ovarian cancer after an average follow-up of 5.1 years {\textpm} 3.8 (range, 0-12.8 years).

It has been previously demonstrated that the health care process (Hripcsak and Albers, 2012, 2013), as defined by measurement context (Hripcsak and Albers, 2013; Albers et al., 2012) and measurement patterns (Albers and Hripcsak, 2010, 2012), can influence how EHR data are distributed statistically (Kohane and Weber, 2013; Pivovarov et al., 2014). We construct an algorithm, PopKLD, which is based on information criterion model selection (Burnham and Anderson, 2002; Claeskens and Hjort, 2008), is intended to reduce and cope with health care process biases and to produce an intuitively understandable continuous summary. The PopKLD algorithm can be automated and is designed to be applicable in high-throughput settings; for example, the output of the PopKLD algorithm can be used as input for phenotyping algorithms. Moreover, we develop the PopKLD-CAT algorithm that transforms the continuous PopKLD summary into a categorical summary useful for applications that require categorical data such as topic modeling. We evaluate our methodology in two ways. First, we apply the method to laboratory data collected in two different health care contexts, primary versus intensive care. We show that the PopKLD preserves known physiologic features in the data that are lost when summarizing the data using more common laboratory data summaries such as mean and standard deviation. Second, for three disease-laboratory measurement pairs, we perform a phenotyping task: we use the PopKLD and PopKLD-CAT algorithms to define high and low values of the laboratory variable that are used for defining a disease state. We then compare the relationship between the PopKLD-CAT summary disease predictions and the same predictions using empirically estimated mean and standard deviation to a gold standard generated by clinical review of patient records. We find that the PopKLD laboratory data summary is substantially better at predicting disease state. The PopKLD or PopKLD-CAT algorithms are not meant to be used as phenotyping algorithms, but we use the phenotyping task to show what information can be gained when using a more informative laboratory data summary. In the process of evaluation our method we show that the different clinical contexts and laboratory measurements necessitate different statistical summaries. Similarly, leveraging the principle of maximum entropy we argue that while some laboratory data only have sufficient information to estimate a mean and standard deviation, other laboratory data captured in an EHR contain substantially more information than can be captured in higher-parameter models.}, language = {eng}, journal = {Journal of Biomedical Informatics}, author = {Albers, D.

METHODS: We reviewed the 2010 American College of Physicians guidance statement on guidelines development and developed our own adaptation. Ancestry search of the American College of Physicians statement identified specific publications that provided additional detail on key steps in the guideline development process, with additional focus given to evidence, equity, and local adaptation considerations. FINDINGS: Our adaptation produced a 5-step process for developing locally optimized protocols for diagnosis and treatment of common conditions seen in MSTs. For specified conditions, this process includes: 1) a focused environmental scan of current practices based on grey literature protocols from MST sending organizations; 2) a review of relevant practice guidelines; 3) a literature review assessing the epidemiology, diagnosis, and treatment of the specified condition; 4) an eDelphi process with experts representing MST and Latin American and the Caribbean partner organizations assessing identified guidelines; and 5) external peer review and summary.

Moreover, studies have shown that some nutritional deficiencies are related to the abnormal development of oocytes and placenta. In Senegal and Morocco, the annual seasonal cycle contains one period with food shortages and the incidence of complete moles is significant. Accordingly, accurate statistical analyses have been performed in these two countries. METHODS: Each month during a one year period, we investigated the occurrence of normal conceptions, molar conceptions and the conception of the future patients in Senegal and Morocco. The comparisons of the conception dates for these three types of conception were analyzed using the Chi-squared test. RESULTS: 94\% of the patients were conceived just prior to the period in the year with food shortages. Consequently, the development of the female embryos occurred under nutritional constraints, which negatively affect the recruitment of the vital factors required for the normal synthesis of DNA, proteins and placental differentiation. DISCUSSIONS: A nutritional deficiency in the mother at conception of their daughter (future patient) is implicated in the higher incidence of CHM in their daughters' filiation. These nutritional deficiencies during the first weeks of pregnancy will have repercussions on the normal development of the oocytes. Accordingly, these developmental impairments take place during the embryonic life of the future mothers of complete moles and not during the conception of the moles themselves.}, language = {eng}, number = {1}, journal = {Placenta}, author = {Coullin, P. and Diatta, A.

MEASUREMENTS: Cancer type-specific cumulative incidence by age 75 years and calendar trends in cumulative incidence and hazard rates, each by HIV status. RESULTS: Cumulative incidences of cancer by age 75 years for persons with and without HIV, respectively, were as follows: Kaposi sarcoma, 4.4\% and 0.01\%; non-Hodgkin lymphoma, 4.5\% and 0.7\%; lung cancer, 3.4\% and 2.8\%; anal cancer, 1.5\% and 0.05\%; colorectal cancer, 1.0\% and 1.5\%; liver cancer, 1.1\% and 0.4\%; Hodgkin lymphoma, 0.9\% and 0.09\%; melanoma, 0.5\% and 0.6\%; and oral cavity/pharyngeal cancer, 0.8\% and 0.8\%. Among persons with HIV, calendar trends in cumulative incidence and hazard rate decreased for Kaposi sarcoma and non-Hodgkin lymphoma. For anal, colorectal, and liver cancer, increasing cumulative incidence, but not hazard rate trends, were due to the decreasing mortality rate trend (-9\% per year), allowing greater opportunity to be diagnosed. Despite decreasing hazard rate trends for lung cancer, Hodgkin lymphoma, and melanoma, cumulative incidence trends were not seen because of the compensating effect of the declining mortality rate. LIMITATION: Secular trends in screening, smoking, and viral co-infections were not evaluated. CONCLUSION: Cumulative cancer incidence by age 75 years, approximating lifetime risk in persons with HIV, may have clinical utility in this population.

CXCR4 was suggested to be responsible for CXCL12-induced biological effects until the recent discovery of its second receptor, CXCR7. Until now, the participation of CXCR7 in CXCL12-induced HSPC cycling and survival is unknown. We show here that CXCL12 was capable of binding CXCR7 despite its scarce expression at CD34(+) cell surface. Blocking CXCR7 inhibited CXCL12-induced Akt activation as well as the percentage of CD34(+) cells in cycle, colony formation, and survival, demonstrating its participation in CXCL12-induced functional effects in HSPCs. At steady state, CXCR7 and β-arrestin2 co-localized near the plasma membrane of CD34(+) cells. After CXCL12 treatment, β-arrestin2 translocated to the nucleus, and this required both CXCR7 and CXCR4. Silencing β-arrestin expression decreased CXCL12-induced Akt activation in CD34(+) cells. Our results demonstrate for the first time the role of CXCR7, complementary to that played by CXCR4, in the control of HSPC cycling, survival, and colony formation induced by CXCL12.

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.

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). Women had a higher relative risk than men, and people {\textless}55 years of age had a higher relative risk than those {\textgreater}55 years of age. Monitoring and medication rates were higher in those with diabetes (all P {\textless} 0.001).

Findings are inconsistent both across primary studies and previous meta-analyses. This study reanalysed 31 primary data sets as a single large sample (N = 2876) to provide a more definitive view. METHOD: Individual patient and control data were obtained from original authors for 11 measures from four common neuropsychological tests: California or Rey Verbal Learning Task (VLT), Trail Making Test (TMT), Digit Span and/or Wisconsin Card Sorting Task. RESULTS: Impairments were found for all 11 test-measures in the bipolar group after controlling for age, IQ and gender (Ps ≤ 0.001, E.S. = 0.26-0.63). Residual mood symptoms confound this result but cannot account for the effect sizes found. Impairments also seem unrelated to drug treatment. Some test-measures were weakly correlated with illness severity measures suggesting that some impairments may track illness progression. CONCLUSION: This reanalysis supports VLT, Digit Span and TMT as robust measures of cognitive impairments in bipolar disorder patients. The heterogeneity of some test results explains previous differences in meta-analyses.

Five experiments therefore investigated the role of executive-attentional and visuospatial resources in both forward and backward digit recall. 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.

Research to objectively assess the impact of stereotype threat for women in academic medicine is feasible and necessary to confirm this hypothesis. Still, a number of conditions present in the academic medicine community today have been shown to trigger stereotype threat in other settings, and stereotype threat fits with existing research on gender in academic medicine. In the meantime, academic health centers should implement relatively simple measures supported by experimental evidence from other settings to reduce the risk of stereotype threat, including (1) introducing the concept of stereotype threat to the academic medicine community, (2) engaging all stakeholders, male and female, to promote identity safety by enacting and making faculty aware of policies to monitor potential instances of discrimination, and training faculty to provide performance feedback that is free of gender bias, (3) counteracting the effects of sex segregation at academic health centers by increasing exposure to successful female leaders, (4) reducing gender stereotype priming by avoiding stereotypically male criteria for promotion, grants, and awards, and (5) building leadership efficacy among female physicians and scientists.}, number = {4}, journal = {Academic Medicine}, author = {Burgess, Diana Jill and Joseph, Anne and van Ryn, Michelle and Carnes, Molly}, month = apr, year = {2012}, pmid = {22361794}, keywords = {Academic Medical Centers, Academic Medical Centers: organization \& administr, Achievement, Faculty, Female, Humans, Leadership, Male, Prejudice, Stereotyping, Women's Rights, medical, physicians, women}, pages = {506--12}, }

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.

Air and human blood samples were collected from 364 adults aged 20-59 years in 1999-2000 National Health and Nutrition Examination Survey (NHANES). Determinants of popKs were identified using weighted multivariate regression models. In the non-smoking population, median popKs ranged from 3.1 to 77.3, comparable to values obtained in the laboratory. PopKs decreased with increasing airborne VOC concentrations. Smoking elevated popKs by 1.5-3.5 times for aromatic compounds, but did not affect the popKs for methyl tert-butyl ether (MTBE) or chlorinated compounds. Drinking water concentration was a modifier of MTBE's popK. Age, gender, body composition, nor ethnicity affected popKs. PopKs were predictable using linear models with air concentration as the independent variable for both adults and children.

Using a modified telomere repeat amplification protocol (TRAP) method to differentiate the telomere G-quadruplex independent effect from dependent ones, we analyzed several ligands that have high affinity and/or selectivity to telomere G-quadruplex.

Given the highly heritable nature of both disorders, studies of the genes explaining the shared origins of the two neurodevelopmental disorders seem particularly called for. Instead of the clinical diagnosis, using neurocognitive measures as (endo)phenotypes that index genetic liability appears a powerful tool in gene finding. We, therefore, extensively reviewed the literature and not only included research wherein ASD and ADHD were compared within a single study, but extended our search also to the separate lines of cognitive neuroscience research.

Although surgery was once reserved for diagnosis alone, the evolution of surgical practices has elevated resection to the treatment of choice for these lesions. While technological advances continue to improve the capacity for gross-total resections and thus decrease the risk of recurrence, ependymoma spinal surgery still contains a variety of potential complications. The presence of neurological deficits and deterioration are not uncommonly associated with spinal cord ependymoma surgery, including sensory loss, dorsal column dysfunction, dysesthetic syndrome, and bowel and bladder dysfunction, particularly in the immediate postoperative period. Surgical treatment may also lead to wound complications and CSF leaks, with increased risk when radiotherapy has been involved. Radiation therapy may also predispose patients to radiation myelopathy and ultimately result in neurological damage. Additionally, resections of spinal ependymomas have been associated with postoperative spinal instability and deformities, particularly in the pediatric population. Despite the advances in microsurgical techniques and intraoperative cord monitoring modalities, there remain a number of serious complications related to the treatment of spinal ependymoma tumors.

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} }

This review will primarily focus on these medical comorbidities, with a brief review of potential future treatments. RECENT FINDINGS: There continues to be disagreement regarding the exact prevalence and etiological significance of gastrointestinal conditions, epilepsy and other abnormal electroencephalographic findings, and sleep problems. It is not clear whether gastrointestinal conditions occur more frequently than in typically developing children, and whether there are distinct conditions that occur more often in ASD than in non-ASD populations. Abnormal electroencephalographic findings have been reported in up to 60\% of children with ASD, and some believe that these abnormalities may be responsible for parts of the ASD phenotype. Sleep problems are reported more frequently than in the general population, and effective treatments are available. Future medical treatments for ASD may be directed at underlying core symptoms and have greater impact than today{\textquoteright}s symptomatic approach.

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.

OBJECTIVE: To determine the 1-year survival in all infants born before 27 gestational weeks in Sweden during 2004-2007. DESIGN, SETTING, AND PATIENTS: Population-based prospective observational study of extremely preterm infants (707 live-born and 304 stillbirths) born to 887 mothers in 904 deliveries (102 multiple births) in all obstetric and neonatal units in Sweden from April 1, 2004, to March 31, 2007. MAIN OUTCOME MEASURES: Infant survival to 365 days and survival without major neonatal morbidity (intraventricular hemorrhage grade {\textgreater}2, retinopathy of prematurity stage {\textgreater}2, periventricular leukomalacia, necrotizing enterocolitis, severe bronchopulmonary dysplasia). Associations between perinatal interventions and survival. RESULTS: The incidence of extreme prematurity was 3.3 per 1000 infants. Overall perinatal mortality was 45\% (from 93\% at 22 weeks to 24\% at 26 weeks), with 30\% stillbirths, including 6.5\% intrapartum deaths. Of live-born infants, 91\% were admitted to neonatal intensive care and 70\% survived to 1 year of age (95\% confidence interval [CI], 67\%-73\%). The Kaplan-Meier survival estimates for 22, 23, 24, 25, and 26 weeks were 9.8\% (95\% CI, 4\%-23\%), 53\% (95\% CI, 44\%-63\%), 67\% (95\% CI, 59\%-75\%), 82\% (95\% CI, 76\%-87\%), and 85\% (95\% CI, 81\%-90\%), respectively. Lower risk of infant death was associated with tocolytic treatment (adjusted for gestational age odds ratio [OR], 0.43; 95\% CI, 0.36-0.52), antenatal corticosteroids (OR, 0.44; 95\% CI, 0.24-0.81), surfactant treatment within 2 hours after birth (OR, 0.47; 95\% CI, 0.32-0.71), and birth at a level III hospital (OR, 0.49; 95\% CI, 0.32-0.75). Among 1-year survivors, 45\% had no major neonatal morbidity. CONCLUSION: During 2004 to 2007, 1-year survival of infants born alive at 22 to 26 weeks of gestation in Sweden was 70\% and ranged from 9.8\% at 22 weeks to 85\% at 26 weeks.}, number = {21}, urldate = {2015-05-26}, journal = {JAMA}, author = {Fellman, Vineta and Hellström-Westas, Lena and Norman, Mikael and Westgren, Magnus and Källén, Karin and Lagercrantz, Hugo and Marsál, Karel and Serenius, Fredrik and Wennergren, Margareta}, month = jun, year = {2009}, pmid = {19491184}, keywords = {Female, Gestational Age, Humans, Infant, Infant Mortality, Infant, Newborn, Infant, Premature, Infant, Premature, Diseases, Infant, Premature, Diseases: mortality, Intensive Care, Neonatal, Male, Morbidity, Perinatal Care, Perinatal Mortality, Pregnancy, Premature Birth, Prospective Studies, Risk, Survival Analysis, Sweden, Sweden: epidemiology}, pages = {2225--33}, }

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.

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.

Analogous insights play a pivotal role in cognitive development: Children discover that object category labels can be organized into hierarchies, friendship networks are organized into cliques, and comparative relations (e.g., "bigger than" or "better than") respect a transitive order. Standard algorithms, however, can only learn structures of a single form that must be specified in advance: For instance, algorithms for hierarchical clustering create tree structures, whereas algorithms for dimensionality-reduction create low-dimensional spaces. Here, we present a computational model that learns structures of many different forms and that discovers which form is best for a given dataset. The model makes probabilistic inferences over a space of graph grammars representing trees, linear orders, multidimensional spaces, rings, dominance hierarchies, cliques, and other forms and successfully discovers the underlying structure of a variety of physical, biological, and social domains.

Here we synthesized 171 studies that manipulated two or more stressors in marine and coastal systems and found that cumulative effects in individual studies were additive (26%), synergistic (36%), and antagonistic (38%). The overall interaction effect across all studies was synergistic, but interaction type varied by response level (community: antagonistic, population: synergistic), trophic level (autotrophs: antagonistic, heterotrophs: synergistic), and specific stressor pair (seven pairs additive, three pairs each synergistic and antagonistic). Addition of a third stressor changed interaction effects significantly in two-thirds of all cases and doubled the number of synergistic interactions. Given that most studies were performed in laboratories where stressor effects can be carefully isolated, these three-stressor results suggest that synergies may be quite common in nature where more than two stressors almost always coexist. While significant gaps exist in multiple stressor research, our results suggest an immediate need to account for stressor interactions in ecological studies and conservation planning.}, bibtype = {article}, author = {Crain, Caitlin Mullan and Kroeker, Kristy and Halpern, Benjamin S}, journal = {Ecology letters}, number = {12} }

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.

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.

The neurobiological basis for internal models is provided by the connectivity and the dynamical properties of neurons. Thus, the interactions between neural tissues and external devices provide a fundamental means for investigating the connectivity and dynamical properties of neural populations. We developed this idea, suggested in the 1980s by Valentino Braitenberg, for investigating and representing the dynamical behavior of neuronal populations in the brainstem of the lamprey. The brainstem was maintained in vitro and connected in a closed loop with two types of artificial device: (a) a simulated dynamical system and (b) a small mobile robot. In both cases, the device was controlled by recorded extracellular signals and its output was translated into electrical stimuli delivered to the neural system. The goal of the first study was to estimate the dynamical dimension of neural preparation in a single-input/single-output configuration. The dynamical dimension is the number of state variables that together with the applied input determine the output of a system. The results indicate that while this neural system has significant dynamical properties, its effective complexity, as established by the dynamical dimension, is rather moderate. In the second study, we considered a more specific situation, in which the same portion of the nervous system controls a robotic device in a two-input/two-output configuration. We fitted the input-output data from the neuro-robotic preparation to neural network models having different internal dynamics and we observed the generalization error of each model. Consistent with the first study, this second experiment showed that a simple recurrent dynamical model was able to capture the behavior of the hybrid system. This experimental and computational framework provides the means for investigating neural plasticity and internal representations in the context of brain-machine interfaces.}, number = {3}, urldate = {2012-07-20}, journal = {J.

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.

Measurements of the levels of mercury in edible muscle of northern fish have been undertaken for over three decades in efforts to evaluate the risks of consuming northern fish. This report summarizes the data obtained from 7974 fish of 25 species from sites distributed from the Yukon to Labrador. The most abundant species were lake trout, lake whitefish, arctic char, walleye, northern pike and burbot. The question being asked was essentially "Are the fish safe to eat?" The results were used to support decisions on fishing and consumption of fish. They were sorted in several ways, into concentration ranges corresponding to human consumption guidelines, into political jurisdictions and into types of bedrock geology. Overall walleye, northern pike and lake trout, usually exceeded the subsistence consumption guideline of 0.2 microg g-1 total mercury and often exceeded the higher guideline of 0.5 microg g-1 total mercury for commercial sales of fish. Mercury in burbot, another facultative predator, was often lower but several still exceeding a guideline. Arctic char collections were mostly from anadromous populations and these had very low levels of mercury, presumably reflecting marine food sources. Lake whitefish were among the cleanest fish examined with 69 of 81 collections falling in the lowest range. Most collections were from sites in sedimentary rock. However a few sites were in metamorphic, intrusive or volcanic rocks and these, taken together, tended to have a higher proportion of sites in the higher ranges of mercury.

Using yeast two hybrid and coimmunoprecipitation assays, we demonstrate that this N-terminal L27 domain of PSD-95beta, binds to an L27 domain in the membrane-associated guanylate kinase calcium/calmodulin-dependent serine kinase, and to Hrs, an endosomal ATPase that regulates vesicular trafficking. By transfecting heterologous cells and hippocampal neurons, we find that interactions with the L27 domain regulate synaptic clustering of PSD95beta.

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.

In outline, the methods involve formal combination through the use of Bayes's theorem of: 1. a prior distribution or belief about the value of a quantity of interest (for example, a treatment effect) based on evidence not derived from the study under analysis, with 2. a summary of the information concerning the same quantity available from the data collected in the study (known as the likelihood), to yield 3. an updated or posterior distribution of the quantity of interest. These methods thus directly address the question of how new evidence should change what we currently believe. They extend naturally into making predictions, synthesising evidence from multiple sources, and designing studies: in addition, if we are willing to quantify the value of different consequences as a 'loss function', Bayesian methods extend into a full decision-theoretic approach to study design, monitoring and eventual policy decision-making. Nonetheless, Bayesian methods are a controversial topic in that they may involve the explicit use of subjective judgements in what is conventionally supposed to be a rigorous scientific exercise. OBJECTIVES: This report is intended to provide: 1. a brief review of the essential ideas of Bayesian analysis 2. a full structured review of applications of Bayesian methods to randomised controlled trials, observational studies, and the synthesis of evidence, in a form which should be reasonably straightforward to update 3. a critical commentary on similarities and differences between Bayesian and conventional approaches 4. criteria for assessing the reporting of a Bayesian analysis 5. a comprehensive list of published 'three-star' examples, in which a proper prior distribution has been used for the quantity of primary interest 6. tutorial case studies of a variety of types 7. recommendations on how Bayesian methods and approaches may be assimilated into health technology assessments in a variety of contexts and by a variety of participants in the research process. METHODS: The BIDS ISI database was searched using the terms 'Bayes' or 'Bayesian'. This yielded almost 4000 papers published in the period 1990-98. All resultant abstracts were reviewed for relevance to health technology assessment; about 250 were so identified, and used as the basis for forward and backward searches. In addition EMBASE and MEDLINE databases were searched, along with websites of prominent authors, and available personal collections of references, finally yielding nearly 500 relevant references. A comprehensive review of all references describing use of 'proper' Bayesian methods in health technology assessment (those which update an informative prior distribution through the use of Bayes's theorem) has been attempted, and around 30 such papers are reported in structured form. There has been very limited use of proper Bayesian methods in practice, and relevant studies appear to be relatively easily identified. RESULTS: Bayesian methods in the health technology assessment context 1. Different contexts may demand different statistical approaches. Prior opinions are most valuable when the assessment forms part of a series of similar studies. A decision-theoretic approach may be appropriate where the consequences of a study are reasonably predictable. 2. The prior distribution is important and not unique, and so a range of options should be examined in a sensitivity analysis. Bayesian methods are best seen as a transformation from initial to final opinion, rather than providing a single 'correct' inference. 3. The use of a prior is based on judgement, and hence a degree of subjectivity cannot be avoided. However, subjective priors tend to show predictable biases, and archetypal priors may be useful for identifying a reasonable range of prior opinion.}, language = {eng}, number = {38}, journal = {Health Technology Assessment (Winchester, England)}, author = {Spiegelhalter, D.

METHODS: ERD/ERS responses of the 4-6, 6-8, 8-10 and 10-12 Hz EEG frequency bands were studied in 24 normal subjects performing a visual sequential letter task (so-called n-back task) in which memory load was varied from 0 to 2. RESULTS: In the 4-6 Hz theta frequency band, a long-lasting synchronization was observed in the anterior electrodes, especially after the presentation of targets. In the 6-8 and 8-10 Hz frequency bands, anterior ERS was elicited especially in the 2-back condition (highest memory load). In contrast to the responses of the 8-10 Hz frequency band, in the 10-12 Hz frequency band the 2-back experimental condition elicited the greatest ERD. CONCLUSIONS: In the highest memory load (2-back) experimental condition the attentional capacities were most probably exceeded, resulting in 6-8 and 8-10 Hz ERS. This might reflect an inhibition of such brain areas (frontal cortices) no longer involved in task completion when alternative strategies are needed and utilized. These more 'cognitive' strategies were then reflected as an increase in 10-12 Hz ERD. Additionally, our results support the assumption that the simultaneously recorded ERD/ERS responses of different narrow EEG frequency bands differ and reflect distinct aspects of information processing.}, number = {11}, urldate = {2015-05-08}, journal = {Clinical neurophysiology : official journal of the International Federation of Clinical Neurophysiology}, author = {Krause, C M and Sillanmäki, L and Koivisto, M and Saarela, C and Häggqvist, A and Laine, M and Hämäläinen, H}, month = nov, year = {2000}, pmid = {11068244}, keywords = {Adult, Brain, Brain: physiology, Cortical Synchronization, Electroencephalography, Evoked Potentials, Evoked Potentials: physiology, Female, Humans, Male, Memory, Memory: physiology}, pages = {2071--8}, }

A brief introduction to the theory of ion confinement in a quadrupole ion trap permits discussion of ion trajectory stability, mass-selective ion ejection, the frequencies of ion motion, and the role of resonant excitation of ion motion. The tandem mass spectrometric examination of PCDDs and PCDFs eluting and co-eluting from a gas chromatographic column is described. Illustrative examples are given of the analysis of field samples containing PCDDs and PCDFs. A comparison is presented of the performance of each of a quadrupole ion trap tandem mass spectrometer, a triple stage quadrupole mass spectrometer, and a sector instrument of relatively high mass resolution for the determination of PCDDs and PCDFs. This comparison is made with respect to instrument tuning, calibration plots, detection limits, ion signals at low concentration, relative response factors, ionization cross-sections, and the examination of field samples. 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. An analytical protocol, based on the variation of molecular ion fragmentation according to the degree (or absence) of chlorine ortho-substitution, has been proposed for distinguishing between toxic and nontoxic PCB congeners.}, bibtype = {article}, author = {Plomley, J B and Lausevic, M and March, R E}, journal = {Mass spectrometry reviews}, number = {5} }

METHODS: Information was obtained from the General Practice Research Database, which contains medical records of general practitioners in England and Wales. The study included 244 235 oral corticosteroid users and 244 235 controls. RESULTS: Patients taking higher doses (at least 7. 5 mg daily of prednisolone or equivalent) had significantly increased risks of non-vertebral fracture [relative rate (RR)=1.44, 95\% confidence interval (CI) 1.34-1.54], hip fracture (RR=2.21, 95\% CI 1.85-2.64) and vertebral fracture (RR=2.83, 95\% CI 2.35-2.40) relative to patients using oral corticosteroids at lower doses (less than 2.5 mg per day). Fracture risk was also elevated among people with higher cumulative exposure to oral corticosteroids over the study period, but this effect was almost wholly removed by adjustment for daily dose, age, gender and other confounding variables. CONCLUSIONS: These findings suggest that the adverse skeletal effects of oral corticosteroids manifest rapidly and are related to daily dose. The level of previous exposure to oral corticosteroids was not a strong determinant of the risk of fracture. Preventive measures against corticosteroid-induced osteoporosis should therefore be instituted as soon after the commencement of glucocorticoid therapy as possible.}, language = {eng}, number = {12}, journal = {Rheumatology (Oxford, England)}, author = {van Staa, T.

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} }

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} }
