Enquiring about traumatic experiences in psychosis: A comparison of case notes and self-report questionnaires

Purpose: Studies have found an association between a history of trauma and the presence of psychotic symptoms. Despite the research evidence it appears to be the case that many clinicians are not routinely asking about traumatic experiences. This study aims to ascertain the level of agreement between rates of self-reported trauma and that which is recorded in case notes.

Methods: The study population was drawn from all individuals with a confirmed diagnosis of psychosis, residing within a defined catchment area. Rates of childhood trauma, lifetime trauma and trauma related to the Troubles in Northern Ireland recorded in participants’ case notes were compared to their responses on self-report questionnaires: THQ, CTQ and TREQ.

Results: Relatively high levels of trauma were reported by participants on the self-report measures that were administered. The rates of trauma recorded in case note records were similar to that found in other studies. Also in line with other research were poor levels of agreement between self-report and case note data.

Conclusion: High levels of lifetime, childhood and trauma related to the Troubles in Northern Ireland were found when the individuals in the sample were directly assessed for the purposes of this study. In contrast much lower rates were recorded in patient notes on routine clinical assessment. The results suggest that clinicians do not routinely enquire about trauma histories with this population and as a result, case notes underestimate trauma prevalence.

Increase in microbial contamination risk with compression of the lid margin in eyes having cataract surgery

Purpose: To assess the bacterial contamination risk in cataract surgery associated with mechanical compression of the lid margin immediately after sterilization of the ocular surface.

Setting: Department of Cataract, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China.

Design: Prospective randomized controlled double-masked trial.

Methods: Patients with age-related cataract were randomly assigned to 1 of 2 groups. In Group A (153 eyes), the lid margin was compressed and scrubbed for 360 degrees 5 times with a dry sterile cotton-tipped applicator immediately after ocular sterilization and before povidone-iodine irrigation of the conjunctival sac. Group B (153 eyes) had identical sterilization but no lid scrubbing. Samples from the lid margin, liquid in the collecting bag, and aqueous humor were collected for bacterial culture. Primary outcome measures included the rate of positive bacterial culture for the above samples. The species of bacteria isolated were recorded.

Results: Group A and Group B each comprised 153 eyes. The positive rate of lid margin cultures was 54.24%. The positive rate of cultures for liquid in the collecting bag was significantly higher in Group A (23.53%) than in Group B (9.80%) (P=.001).The bacterial species cultured from the collecting bag in Group B were the same as those from the lid margin in Group A. The positive culture rate of aqueous humor in both groups was 0%.

Conclusion: Mechanical compression of the lid margin immediately before and during cataract surgery increased the risk for bacterial contamination of the surgical field, perhaps due to secretions from the lid margin glands.

The ethics of ethical debates in peace and conflict research: Notes towards the development of a research covenant

This article outlines the case for peace and conflict researchers to formulate a research covenant to better shape their ethical obligations and responsibilities. This is an urgent necessity given that ethical debates have in some proponents become emotive and are not conducted in an ethical manner. In coming to this assessment, the article reviews trends in the research ethics literature and draws out some of the generic issues addressed in a review of the personal reflexivity that an assortment of individual peace and conflict researchers have engaged in when recounting their fieldwork experiences. These generic issues are reformulated in an attempt to codify appropriate ethical practice in peace and conflict research, and they go towards determining the contents of the research covenant. It is suggested that the research covenant is a more ethical way to debate the ethics of peace and conflict research.

Multi-scale dynamics on the Eastern Brazilian margin

Este trabalho combina esforços de simulação numérica e de análise de dados para investigar a dinâmica em diversos compartimentos (oceano aberto, plataforma continental e zona costeira-estuarina) e, em multiplas escalas, na Margem Continental Leste Brasileira (MCLB). A circulação de largo e mesoescala espacial e a propagação da maré barotrópica são investigadas através de uma configuração aninhada do modelo numérico ROMS. O estudo da dinâmica regional da Baía de Camamu (CMB) baseia-se na análise de dados locais. A MCLB, localizada a SW do Atlântico Sul entre 8±S e 20±S, possui plataforma estreita, batimetria complexa, e baixa produtividade primária. A sua dinâmica é influenciada pela divergência da Corrente Sul Equatorial (CSE). As simulações refletem as conexões sazonais e espaciais entre a Corrente do Brasil e a Contra Corrente Norte do Brasil , em conexão com a dinâmica da CSE. As simulações revelam atividades vorticais nas proximidades da costa e interações com a dinâmica costeira, cujos padrões são descritos. A validação do modelo em mesoescala é baseada em cálculos de energia cinética turbulenta e em dados históricos de transporte. A CMB, localizada a 13±400S, abriga uma comunidade piscatória tradicional e extenso de manguezal. Situa-se porém sobre uma bacia sedimentar com grande reservas de óleo e gás, estando em tensão permanente de impacto ambiental. Neste trabalho sumarizamos as condições físicas regionais e investigamos sua dinâmica interna, focando sua variabilidade em amostragens realizadas sob condições de seca (Setembro de 2004) e de chuva (Julho de 2005). Finalmente, o modelo numérico ROMS é forçado com o sinal de maré, empregando-se uma configuração simples (com coeficientes de atrito de fundo constantes e condições hidrográficas homogéneas), com o intuito de avaliar sua resposta e investigar a natureza da propagação da maré barotrópica na MCLB, convergindo na CMB. A análise da resposta do modelo à maré basea-se em séries históricas do nível do mar para a MCLB e dados recentes da CMB.

Pathways of recent fine-grained sediment transport on the central Portuguese continental margin

Com o intuito de estudar as principais vias de transporte de sedimentos finos recentes na zona central da margem continental Oeste Portuguesa, parâmetros geoquímicos, mineralógicos e granulométricos foram analisados em sedimentos superficiais e em matéria particulada colhida em armadilhas de sedimentos e integrados com observações da hidrodinâmica de fundo. Os parâmetros geoquímicos foram também estudados na coluna de sedimentos depositada nos últimos 150 anos e em sedimentos pré-industriais. Os referidos parâmetros determinados foram: concentrações elementares, isótopos estáveis de Pb, teores em materiais litogénicos, carbonato de cálcio e carbono orgânico. Os canhões de Lisboa-Setúbal e Cascais tiveram especial destaque no presente estudo dado que, até à data, encontram-se menos estudados que o Canhão da Nazaré. Os resultados mostram que a distribuição de sedimentos na zona central da margem ocidental Portuguesa é particionada pelos canhões e que a exportação de sedimentos da plataforma para zonas mais profundas da margem é restringida pelas correntes do talude, excepto onde os canhões funcionam como corredores para o transporte de sedimentos. Enquanto no Canhão de Lisboa-Setúbal, e provavelmente no Canhão de Cascais, o transporte de sedimentos até à zona inferior é limitada, provavelmente apenas despoletado por eventos de elevada energia, no Canhão da Nazaré o transporte ao longo do todo o canhão parece eficiente. As zonas superiores dos canhões de Lisboa-Setúbal e Cascais presentemente actuam como armadilhas de sedimentos finos, aprisionando partículas em suspensão provenientes da plataforma adjacente. A introdução directa de sedimentos provenientes das plumas dos rios Tejo e Sado nas zonas superiores dos canhões parece limitada, contudo a resuspensão dos sedimentos do prodelta do Tejo como resultado de ondas de tempestade e ondas de maré interna permite o transporte de sedimentos para os canhões adjacentes. Na plataforma de Lisboa-Setúbal-Sines foram identificadas as assinaturas geoquímicas e mineralógicas de diferentes fontes de sedimentos finos (e.g. estuários do Tejo e Sado, arribas costeiras, lagoas de St. André e Melides). As concentrações elementares pré-industriais são muito semelhantes nos canhões da Nazaré e Lisboa-Setúbal, mas variados graus de enriquecimento antrópico de metais traço estão presentes nos sedimentos recentes. A mais acentuada influência antrópica na última área referida é consistente com a sua proximidade a áreas densamente povoadas e industrializadas e com input de sedimentos originários dos rios Tejo e Sado, potenciais transportadores de partículas poluentes. A dispersão de Pb atmosférico parece também significativa sendo que toda a zona da plataforma continental adjacente aos canhões de Lisboa-Setúbal e Cascais apresenta-se enriquecida. A principal fonte de Pb antrópico identificada através de isótopos estáveis de Pb é consistente com a assinatura das cinzas de incineradoras. No Canhão de Lisboa a imersão de dragados contaminados parece ser também uma potencial importante fonte de metais traço antropogénicos.

Modeling the Western Iberian margin circulation: present and future

The purpose of this work is to carry out a comprehensive study on the Western Iberian Margin (WIM) circulation my means of numerical modeling, and to postulate what this circulation will be in the future. The adopted approach was the development of a regional ocean model configuration with high resolution, capable of reproducing the largeand small-scale dynamics of the coastal transition zone. Four numerical experiences were carried out according to these objectives: (1) a climatological run, in order to study the system’s seasonal behavior and its mean state; (2) a run forced with real winds and fluxes for period 2001-2011 in order to study the interannual variability of the system; (3) a run forced with mean fields from Global Climate Models (GCMs) for the present, in order to validate GCMs as adequate forcing for regional ocean modeling; (4) a similar run (3) for period 2071-2100, in order to assess possible consequences of a future climate scenario on the hydrography and dynamics of the WIM. Furthermore, two Lagrangian particle studies were carried out: one in order to trace the origin of the upwelled waters along the WIM; the other in order to portrait the patterns of larval dispersal, accumulation and connectivity. The numerical configuration proved to be adequate in the reproduction of the system’s mean state, seasonal characterization and an interannual variability study. There is prevalence of poleward flow at the slope, which coexists with the upwelling jet during summer, although there is evidence of its shifting offshore, and which is associated with the Mediterranean Water flow at deeper levels, suggesting a barotropic character. From the future climate scenario essay, the following conclusions were drawn: there is general warming and freshening of upper level waters; there is still poleward tendency, and despite the upwellingfavorable winds strengthening in summer the respective coastal band becomes more restricted in width and depth. In what concerns larval connectivity and dispersion along the WIM, diel vertical migration was observed to increase recruitment throughout the domain, and while smooth coastlines are better suppliers, there is higher accumulation where the topography is rougher.
