RESUMEN

BACKGROUND: Drinking alcohol during pregnancy is associated with Foetal Alcohol Spectrum Disorders (FASD), and women who drink at higher levels are more likely to have a baby with FASD. Public health responses focus on population-level approaches to FASD prevention such as promoting abstinence and alcohol brief interventions. Efforts to better understand and respond to 'high risk' drinking during pregnancy have been largely ignored. This meta-ethnography of qualitative research aims to inform this policy and practice agenda. METHODS: Ten health, social care, and social sciences databases were searched for qualitative studies published since 2000 exploring drinking during pregnancy. Studies that included accounts of women who described themselves, or were diagnosed as, alcohol-dependent during pregnancy, or reported drinking during pregnancy at levels considered by the Word Health Organisation to constitute 'high risk' drinking, were eligible. Noblit and Hare's analytic approach to meta-ethnography was used to synthesise the studies and eMERGe reporting guidance was followed. RESULTS: Nine diverse studies were included. All explored the impact of social norms and relationships, women's knowledge about the risks involved in drinking during pregnancy, the behaviour of women, and the advice they received. Three key themes were identified: drinking is social and relational, knowledge is not enough, and multiple adversities matter. Multiple adversities were interconnected and primarily related to structural inequalities and oppression. The complex needs of women and the wider context in which their drinking occurred were rarely explored or responded to during pregnancy. CONCLUSION: This meta-ethnography provides a more nuanced understanding of the complex dynamics involved in women's 'high risk' drinking during pregnancy, the contexts in which they drink and their unmet needs. These findings can inform future policy and practice responses to 'high risk' drinking during pregnancy. Further research should explore women's experiences in a UK context and consider how services could meet women's needs.

RESUMEN

Learning to predict rewards based on environmental cues is essential for survival. It is believed that animals learn to predict rewards by updating predictions whenever the outcome deviates from expectations, and that such reward prediction errors (RPEs) are signaled by the mesolimbic dopamine system-a key controller of learning. However, instead of learning prospective predictions from RPEs, animals can infer predictions by learning the retrospective cause of rewards. Hence, whether mesolimbic dopamine instead conveys a causal associative signal that sometimes resembles RPE remains unknown. We developed an algorithm for retrospective causal learning and found that mesolimbic dopamine release conveys causal associations but not RPE, thereby challenging the dominant theory of reward learning. Our results reshape the conceptual and biological framework for associative learning.

RESUMEN

Over the last three decades, researchers have investigated population density and health outcomes at differing scale. There has not been a systematic review conducted in order to synthesise this evidence. Following the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines, we systematically reviewed quantitative evidence published since 1990 on population density and non-communicable disease (NCD) within Westernised countries. Fifty-four studies met the inclusion criteria and were evaluated utilising a quality assessment tool for ecological studies. High population density appears to be associated with higher mortality rates of a range of cancers, cardiovascular disease and COPD, and a higher incidence of a range of cancers, asthma and club foot. In contrast, diabetes incidence was found to be associated with low population density. High and low population density are therefore risk markers for a range of NCDs, indicating that there are unidentified factors and mechanisms underlying aetiology. On closer examination, our synthesis revealed important and complex relationships between population density, the built environment, the nature of greenspace and man-made exposures. In light of increasing rates of morbidity and mortality, future research is required to investigate these associations in order to establish causative agents for each NCD.

RESUMEN

Human African trypanosomiasis, or sleeping sickness, is a neglected tropical disease caused by Trypanosoma brucei rhodesiense and Trypanosoma brucei gambiense which seriously affects human health in Africa. Current therapies present limitations in their application, parasite resistance, or require further clinical investigation for wider use. Our work herein describes the design and syntheses of novel antitrypanosomal 4-phenyl-6-(pyridin-3-yl)pyrimidines, with compound 13, the 4-(2-methoxyphenyl)-6-(pyridine-3-yl)pyrimidin-2-amine demonstrating an IC50 value of 0.38 µM and a promising off-target ADME-Tox profile in vitro. In silico molecular target investigations showed rhodesain to be a putative candidate, supported by STD and WaterLOGSY NMR experiments, however, in vitro evaluation of compound 13 against rhodesain exhibited low experimental inhibition. Therefore, our reported library of drug-like pyrimidines present promising scaffolds for further antikinetoplastid drug development for both phenotypic and target-based drug discovery.

RESUMEN

A study of dialectical behaviour therapy (DBT) for 16 older female adolescents with persistent and severe deliberate self-harm was undertaken. Independent assessments were carried out pre- and post-treatment, and at eight months follow-up. On average subjects completed more than 78% of sessions. There was a marked reduction in self reported depression (F = 12.8, df = 2, p < .001); hopelessness (F = 15.9, df = 2, p < .001); episodes of deliberate self-harm (F = 23.9, df = 2, p < .001); alongside an increase in general functioning (F = 22.9, df = 2, p < .001).
