Depression associates with Mini Nutritional Assessment (MNA), Vitamin B12 and Folate status::Findings from Belfast Elderly Longitudinal Free-Living Ageing STudy (BELFAST)

Introduction: An association between depression and folate has been found in clinical studies. Depression and dementia can contribute to nutritional deficiency. This study clinical depression in in octo/nonagenarians from the BELFAST study.
Method: In the BELFAST study, 38 free-living octo/nonagenarians (mean age 82 years), who apparently well and cognitively intact were followed up at 5 years and assessed using the Geriatric Depression Scale (GDS), Folstein (30 point), Mini Nutritional Assessment Tool (MNA) together with serum folate and vitamin B12 levels.
Results: Mean GDS was 3.4 (SD 2.5), serum folate 7.1 umol/l (SD 5.3) and B12 553 umol/l (458). With mean MNA and Folstein -25.8 (SD 2.7) and 27.6 (SD 2.7) respectively with no sex difference (p = 0.78; p = 0.36). 25% of subjects showed a GDS >5 indicating risk of mild depression and 21% had compromised nutritional status. MNA associated with GDS in male (r2 = 0.56 p = 0.01), but not in female elderly subjects (r2 = 0.01; p = 0.44). GDS score and lower serum folate were associated (r2 = -0.23; p = 0.01).
Conclusion: Overall there was the suggestion that nutritional status and depression might be linked in male subjects at 5 year follow-up in octo/nonagenarians from the BEFLAST study. The lower folate in subjects categorised at risk of mild depression might suggest vitamin supplementation could be useful.

Environmental Affordances and Children in Post-conflict Belfast

This paper examines the experiences of children in post-conflict Belfast as peace and social change afford new opportunities at the same time as they regulate behaviours and spatial practices. Theoretically and empirically it draws on the concept of environmental affordances in order to map the experiences of 11-year-old children in separate inner-city segregated and middle-class communities. Whilst the recession has affected the pace of urban restructuring, children in the expanding mixed and largely middleclass city extract multiple advantages from their area in ways not available to segregated communities. The paper concludes by highlighting the implications for effective listening strategies in the management of divided communities. © 2011 Taylor & Francis.

Incidence of colorectal cancer in a population-based cohort of patients with Barrett's oesophagus

Objective. Previous studies have shown a positive association between colorectal cancer and Barrett's oesophagus, but this association is disputed. No population-based studies have examined the incidence of this cancer in patients with Barrett's oesophagus. Material and methods. The present study comprised a population-based cohort of patients with Barrett's oesophagus (constructed using pathology reports of all oesophageal biopsies in Northern Ireland 1993-99; cohort subclassified according to whether specialized intestinal metaplasia (SIM) was present, absent, or not commented on in biopsies). Cases of colorectal cancer were identified by linking with the Northern Ireland Cancer Registry. The comparison group used was the general population in Northern Ireland. Results. A total of 2969 patients with Barrett's oesophagus were followed for a total of 14,014 person-years (mean 4.7 years). SIM was present in 1670 patients (56.2%), absent in 545 (18.4%) and not commented on in 754 (25.4%). Colorectal cancer was diagnosed in 39 patients; 22 patients had cancer diagnosed at least 6 months after diagnosis of Barrett's oesophagus. There was no increased risk of colorectal cancer: the standardized incidence ratio (SIR) for cancer diagnosed at least 6 months after entry into the cohort was 0.82 (95% CI, 0.48-1.17); this risk did not alter with SIM status or gender. To assess a possible effect of diagnostic bias, we calculated SIRs for cancers occurring after at least 3 months, after at least 1 month and at any time after diagnosis of Barrett's oesophagus. These were 0.94 (0.57-1.30), 1.09 (0.69-1.48) and 1.46 (1.00-1.92), respectively. Conclusions. The incidence of colorectal cancer was not elevated in patients with Barrett's oesophagus. Diagnostic bias may explain why previous studies have found an association. © 2005 Taylor & Francis.

An inherited duplication at the gene p21 Protein-Activated Kinase 7 (PAK7) is a risk factor for psychosis

Identifying rare, highly penetrant risk mutations may be an important step in dissecting the molecular etiology of schizophrenia. We conducted a gene-based analysis of large (>100kb), rare copy number variants (CNVs) in the Wellcome Trust Case Control Consortium 2 (WTCCC2) schizophrenia sample of 1,564 cases and 1,748 controls all from Ireland, and further extended the analysis to include an additional 5,196 UK controls. We found association with duplications at chr20p12.2 (P=0.007) and evidence of replication in large independent European schizophrenia (P=0.052) and UK bipolar disorder case-control cohorts (P=0.047). A combined analysis of Irish/UK subjects including additional psychosis cases (schizophrenia and bipolar disorder) identified 22 carriers in 11,707 cases and 10 carriers in 21,204 controls (meta-analysis CMH P value=2x10(-4) (odds ratio (OR)=11.3, 95% CI=3.7, ∞)). Nineteen of the 22 cases and 8 of the 10 controls carried duplications starting at 9.68Mb with similar breakpoints across samples. By haplotype analysis and sequencing we identified a tandem ∼149kb duplication overlapping the gene p21 Protein-Activated Kinase 7 (PAK7, also called PAK5) which was in linkage disequilibrium with local haplotypes (P=2.5x10(-21)), indicative of a single ancestral duplication event. We confirmed the breakpoints in 8/8 carriers tested and found co-segregation of the duplication with illness in two additional family members of one of the affected probands. We demonstrate that PAK7 is developmentally co-expressed with another known psychosis risk gene (DISC1) suggesting a potential molecular mechanism involving aberrant synapse development and plasticity.

Two Trilogies:On Stewart Parker and Tom Murphy

This chapter discusses the relations between Irish cinema and the other arts- chiefly, literature, theatre, painting, and photography. It provides a critical overview of the main scholarly approaches to those forms of adaptation and citation that have tended to dominate Irish film production. It argues that factors such as the historic marginalization of non-literary modernist art in Ireland, a deep cultural resistance to intellectual and politically-engaged filmmaking, and a commercially-driven attachment to formulaic narrative structures, are among the reasons why Ireland has generally failed to produce a distinctive and successful cinema. The chapter concludes by discussing some films that have resisted this trend by offering their audiences a more creative approach to -- or poetics of -- adaptation that has more in common with the visual -- rather than literary -- arts in Ireland.

From Francis Hutcheson to James McCosh: Irish Presbyterians and Defining the Scottish Philosophy in the Nineteenth Century

This article examines the disputes amongst Irish Presbyterians about the teaching of moral philosophy by Professor John Ferrie in the college department of the Royal Belfast Academical Institution in the early nineteenth century and the substantive philosophical and theological issues that were raised. These issues have largely been ignored by Irish historians, but a discussion of them is of general relevance to historians of ideas as they illuminate a series of broader questions about the definition and development of Scottish philosophy. These are represented in the move from two philosophers who had strong connections with Irish Presbyterianism—Francis Hutcheson, the early eighteenth-century moral sense philosopher and theological moderate from County Down, and James McCosh, nineteenth-century exponent of modified Common Sense philosophy at Queen's College Belfast and a committed evangelical. In particular, this article addresses three important themes—the definition and character of ‘the Scottish philosophy’, the relationship between evangelicalism and Common Sense philosophy, and the process of development and adaptation that occurred in eighteenth-century Scottish thought during the first half of the nineteenth century.
