Dental specialists treat conditions such as facial trauma and oral cancer that can result from alcohol misuse. Visits to primary dental care professionals are oriented towards prevention. Interventions coordinated by specialist services but delivered strategically in primary care could therefore potentially help to reduce burdens on secondary care services. The aim of this study was to determine the feasibility of screening for alcohol misuse and providing brief intervention in a primary dental care setting. ⋯ Royal College of Surgeons of England.

Obesity is an emergent epidemic associated with morbidity, mortality, and psychosocial effects. One of the key gut hormones that controls appetite is peptide tyrosine-tyrosine 3-36 (PYY3-36) whose circulating half-life is only 8 min. A long-acting analogue of PYY3-36 would therefore have great potential as an antiobesity agent. The aims of this study were to investigate the effect of various aminoacid modifications of PYY3-36 on pharmacokinetics and their ability to suppress food intake. ⋯ UK Medical Research Council, Biotechnology and Biological Sciences Research Council, National Institute for Health Research (NIHR), an Integrative Mammalian Biology (IMB) Capacity Building award, an FP7-HEALTH-2009-241592 EuroCHIP grant, NIHR Imperial Biomedical Research Centre Funding Scheme.

The mechanism responsible for left ventricular dysfunction after cardiac surgery is only partly understood. In isolated rat hearts subjected to an ischaemia-reperfusion protocol, left ventricular dysfunction was associated with uncoupling of endothelial nitric oxide synthase (NOS) activity secondary to oxidation of the NOS cofactor, tetrahydrobiopterin (BH4). Here we investigated the effect of cardiopulmonary bypass and reperfusion on myocardial nitroso-redox balance in patients undergoing cardiac surgery. ⋯ British Heart Foundation.

Increased expression of antimicrobial peptides including human beta defensins (HBD) has been reported in the amniotic fluid and vaginal secretions of women who deliver preterm. We have previously shown that these women have increased first trimester serum HBD2. The gene encoding HBD2, DEFB4A, is part of a defensin beta (DEFB) cluster on chromosome 8 that is variable in copy number. Increased serum HBD2 is associated with increased DEFB copy number. We aimed to test the hypothesis that variation in DEFB copy number is associated with preterm birth. ⋯ Wellcome Trust, Wellbeing of Women.

Implementation of the National Early Warning Score in the National Health Service (NHS) has renewed focus on prompt identification and referral of the deteriorating ward patient. A large body of published work suggests that delay in both referral and admission to critical care can be associated with poor outcomes. We sought to explore factors associated with early provision of respiratory support in a cohort of deteriorating ward patients referred to the critical care team. ⋯ Wellcome Trust, National Institute for Health Service Support Costs, Intensive Care National Audit & Research Centre.
