The article examines whether there are disparities in the prevalence of structural brain abnormalities in white and black first-episode psychosis patients in Great Britain. Results reveal no evidence in support of the hypothesis. Compared with ethnic controls, white British patients and African-Caribbean/black African patients had ventricular enlargement and increased lenticular nucleus volume. African-Caribbean/black African patients had reduced global grey matter and increased lingual gyrus grey-matter volume.

In order to determine the prevalence and risk factors for necrotic enteritis in broilers, a cross-sectional survey was conducted among 857 farms, rearing broilers for nine UK poultry companies. The main data collection tool was a postal questionnaire directed at farm managers. Additional information on disease occurrence on the farm was collected from veterinary postmortem reports. The response rate to the questionnaire was 75%, ranging from 54% to 90% within companies. During 2001, 32.8% of the respondents indicated that they had observed a case of necrotic enteritis (95% confidence interval, 29.1 to 36.8) in at least one flock. The disease was most often reported during the months October to February. The point prevalence (necrotic enteritis occurrence in the most recently reared flock) reported by farm managers was 12.3% (95% confidence interval, 9.8 to 15.2). Multilevel logistic regression was performed with the poultry company as the random effect, using the occurrence of necrotic enteritis in the farm's most recently reared flock as the dependent variable. Strong associations were found between the outcome variable and the occurrence of wet litter (odds ratio, 2.39; 95% confidence interval, 1.27 to 4.52; P=0.007) and coccidiosis (odds ratio, 4.68; 95% confidence interval, 1.74 to 12.55; P=0.002). In addition, the use of ammonia as a disinfectant for coccidial oocysts appeared to be an independent risk factor (odds ratio, 3.44; 95% confidence interval, 1.53 to 7.71; P=0.003). Finally, the positive association between the use of plasterboard walls in poultry houses and the occurrence of necrotic enteritis might point to an important role of cleaning and disinfection in the epidemiology of this disease (odds ratio, 3.72; 1.38 to 10.00; P=0.009).

Despite the clinical benefits and safety profile of primary percutaneous coronary intervention (PCI), the health care system in the UK has been slow to adopt this strategy as first line management for ST segment elevation myocardial infarction. The cost implications of a 24 hour a day, seven days per week primary PCI service and the absence of an existing efficient working model within the National Health Service (NHS) framework are two of the major deterrents for provision of such a service. The existent cost effectiveness data for primary PCI is critically reviewed, with particular reference to the NHS. [ABSTRACT FROM AUTHOR]

The article discusses a study that discusses the role of a workplace-based risk assessment in improving a lifetime cardiovascular disease risk in male steelworkers in Great Britain. It informs that the study included a sample of male employees from a local steelworks in Carmarthenshire, South Wales, and undergone cardiovascular disease (CVD) and diabetes risk assessment and the results showed that workplace-based CVD initiatives were beneficial to shift workers.

BackgroundThere is evidence that a range of socio-environmental exposures is associated with an increased risk of psychosis. However, despite the fact that such factors probably combine in complex ways to increase risk, the majority of studies have tended to consider each exposure separately. In light of this, we sought to extend previous analyses of data from the AESOP (Aetiology and Ethnicity in Schizophrenia and Other Psychoses) study on childhood and adult markers of disadvantage to examine how they combine to increase risk of psychosis, testing both mediation (path) models and synergistic effects.MethodAll patients with a first episode of psychosis who made contact with psychiatric services in defined catchment areas in London and Nottingham, UK (n = 390) and a series of community controls (n = 391) were included in the AESOP study. Data relating to clinical and social variables, including parental separation and loss, education and adult disadvantage, were collected from cases and controls.ResultsThere was evidence that the effect of separation from, but not death of, a parent in childhood on risk of psychosis was partially mediated through subsequent poor educational attainment (no qualifications), adult social disadvantage and, to a lesser degree, low self-esteem. In addition, there was strong evidence that separation from, but not death of, a parent combined synergistically with subsequent disadvantage to increase risk. These effects held for all ethnic groups in the sample.ConclusionsExposure to childhood and adult disadvantage may combine in complex ways to push some individuals along a predominantly sociodevelopmental pathway to psychosis.

Background. Childhood adversity has been associated with onset of psychosis in adulthood but these studies have used only general definitions of this environmental risk indicator. Therefore, we sought to explore the prevalence of more specific adverse childhood experiences amongst those with and without psychotic disorders using detailed assessments in a large epidemiological case-control sample (AESOP). Method. Data were collected on 182 first-presentation psychosis cases and 246 geographically matched controls in two UK centres. Information relating to the timing and frequency of exposure to different types of childhood adversity (neglect, antipathy, physical and sexual abuse, local authority care, disrupted living arrangements and lack of supportive figure) was obtained using the Childhood Experience of Care and Abuse Questionnaire. Results. Psychosis cases were three times more likely to report severe physical abuse from the mother that commenced prior to 12 years of age, even after adjustment for other significant forms of adversity and demographic confounders. A non-significant trend was also evident for greater prevalence of reported severe maternal antipathy amongst those with psychosis. Associations with maternal neglect and childhood sexual abuse disappeared after adjusting for maternal physical abuse and antipathy. Paternal maltreatment and other forms of adversity were not associated with psychosis nor was there evidence of a dose--response effect. Conclusions. These findings suggest that only specific adverse childhood experiences are associated with psychotic disorders and only in a minority of cases. If replicated, this greater precision will ensure that research into the mechanisms underlying the pathway from childhood adversity to psychosis is more fruitful. [ABSTRACT FROM AUTHOR]

Abstract: Background: Family involvement in help-seeking is associated with a shorter duration of untreated psychoses [DUP], but it is unknown whether neighbourhood-level factors are also important. Methods: DUP was estimated for all cases of first-episode psychoses identified over 2 years in 33 Southeast London neighbourhoods (n=329). DUP was positively skewed and transformed to the natural logarithm scale. We fitted various hierarchical models, adopting different assumptions with regard to spatial variability of DUP, to assess whether there was evidence of neighbourhood heterogeneity in DUP, having accounted for a priori individual-level confounders. Results: Neighbourhood-level variation in DUP was negligible compared to overall variability. A non-hierarchical model with age, sex and ethnicity covariates, but without area-level random effects, provided the best fit to the data. Discussion: Neighbourhood factors do not appear to be associated with DUP, suggesting its predictors lie at individual and family levels. Our results inform mental healthcare planning, suggesting that in one urbanised area of Southeast London, where you live does not affect duration of untreated psychosis. [Copyright &y& Elsevier]

Abstract: In 2004, the United Kingdom began for the first time a systematic, countrywide initiative to increase organ donations. The approach, based on international research and with consultation from the United States, entailed encouraging the early identification and referral of potential donors, training critical care physicians in breaking bad news and in collaborating with donor coordinators, training coordinators in donation conversation skills, and getting them in to speak with families. The strategy represented a large culture change in the procurement of organs in the United Kingdom and has met resistance. However, the change has started to take hold and, despite a dramatic and unexpected 21% reduction in potential brain stem death donors over a 4-year period, is showing positive results. Herein we have described the historical model for procuring organs in the United Kingdom, the development of the new strategy, its components, and the results of its implementation, in terms of earlier referrals, the identification of non–heart-beating donors, the collaboration between physicians and coordinators in speaking with families and in converted donors.

Objective:  We sought to investigate the prevalence and social correlates of psychotic-like experiences in a general population sample of Black and White British subjects. Method:  Data were collected from randomly selected community control subjects, recruited as part of the ÆSOP study, a three-centre population based study of first-episode psychosis. Results:  The proportion of subjects reporting one or more psychotic-like experience was 19% ( n = 72/372). These were more common in Black Caribbean (OR 2.08) and Black African subjects (OR 4.59), compared with White British. In addition, a number of indicators of childhood and adult disadvantage were associated with psychotic-like experiences. When these variables were simultaneously entered into a regression model, Black African ethnicity, concentrated adult disadvantage, and separation from parents retained a significant effect. Conclusion:  The higher prevalence of psychotic-like experiences in the Black Caribbean, but not Black African, group was explained by high levels of social disadvantage over the life course.

BackgroundNumerous studies have reported high rates of psychosis in the Black Caribbean population in the UK. Recent speculation about the reasons for these high rates has focused on social factors. However, there have been few empirical studies. We sought to compare the prevalence of specific indicators of social disadvantage and isolation, and variations by ethnicity, in subjects with a first episode of psychosis and a series of healthy controls.MethodAll cases with a first episode of psychosis who made contact with psychiatric services in defined catchment areas in London and Nottingham, UK and a series of community controls were recruited over a 3-year period. Data relating to clinical and social variables were collected from cases and controls.ResultsOn all indicators, cases were more socially disadvantaged and isolated than controls, after controlling for potential confounders. These associations held when the sample was restricted to those with an affective diagnosis and to those with a short prodrome and short duration of untreated psychosis. There was a clear linear relationship between concentrated disadvantage and odds of psychosis. Similar patterns were evident in the two main ethnic groups, White British and Black Caribbean. However, indicators of social disadvantage and isolation were more common in Black Caribbean subjects than White British subjects.ConclusionsWe found strong associations between indicators of disadvantage and psychosis. If these variables index exposure to factors that increase risk of psychosis, their greater prevalence in the Black Caribbean population may contribute to the reported high rates of psychosis in this population.

A postal questionnaire was sent to the managers of 857 broiler farms in the UK to determine the prevalence and risk factors for wet lifter. The response rate was 75 percent. Wet litter was reported by 75 per cent (95 percent confidence interval [cl] 71.3 to 78.3) of the respondents in at least one flock during the year 2001 and 56.1 percent (95 percent cl 52.O to 60.0) of them reported that they had an outbreak of wet litter in their most recently reared flock. Wet litter occurred more often during the winter months and farms using side ventilation systems were at an increased risk (odds ratio 1.74; 95 percent cl 1.09 to 2.76). A multivariable analysis was carried out using two different definitions of wet litter as outcome variables - all cases of wet litter, and cases of wet litter associated with disease. Consistent risk factors for both outcomes were coccidiosis, feed equipment failures and the availability of separate farm clothing for each house. Cases of wet lifter associated with disease were reported by 33.7 percent (95 per cent cl 28.8 to 39.1) of the managers in their last flock and were associated with the use of hand sanitisers and broiler houses with walls made of concrete.
