Pregnancies are increasingly seen in women with a gastric band, but no guidance exists on band management during pregnancy. Although band inflation can prevent excessive gestational weight gain and its associated complications, it might have detrimental effects on fetal growth. We compared maternal and perinatal outcomes according to band management strategy-keeping the band inflated throughout pregnancy versus deflation. ⋯ Bristol Bariatric Pregnancy Research Hub.

Somatic activating mutations in PIK3CA, which encodes the p110α catalytic subunit of phosphoinositide-3-kinase (PI3K) are frequently found in cancers and have been identified in a spectrum of mosaic overgrowth disorders ranging from isolated digit enlargement to more extensive overgrowth of the body, brain, or vasculature. We aimed to study affected dermal fibroblasts with a view to inform therapeutic studies, and to observe cancer-associated mutations in isolation. ⋯ Wellcome Trust, Sackler Fund, National Instititute for Health Research.

Outcome reporting in bariatric surgery needs uniformity. A core outcome set is an agreed minimum set of outcomes reported in all studies of a particular condition, but members of the bariatric multidisciplinary team might value outcomes differently. The aim of this study was to summarise existing outcome reporting in bariatric surgery, to inform the development of a core outcome set, and to compare outcomes selected as important by type of health professional. ⋯ National Institute for Health Research (NIHR), and the NIHR Health Technology Assessment programme. This work was also undertaken with the support of the MRC ConDuCT-II Hub (Collaboration and innovation for Difficult and Complex randomised controlled Trials In Invasive procedures, MR/K025643/1).

We have previously shown that patients with endometrial carcinoma express elevated concentrations of the endocannabinoid, anandamide (AEA), in both their plasma and their endometrial tissue and that the endometrial carcinoma cell line, Ishikawa, contains the receptors to which AEA binds. Several studies have reported that human and rodent cancer cell lines die in response to high AEA concentrations. The incidence of endometrial carcinoma continues to escalate and, although surgical treatment has improved, morbidity and mortality rates have not. A move towards a novel non-surgical therapeutic option is thus required, and the endocannabinoid system provides a good candidate target. We aimed to investigate the effects of AEA on the survival and proliferation of an endometrial carcinoma cell model. ⋯ University Hospitals of Leicester NHS Trust.

Retinitis pigmentosa, which affects one in 3000 people, causes blindness and has no treatment. Mutations in the retinitis pigmentosa GTPase regulator (RPGR) gene cause 20% of all cases. Recent work suggests that RPGR, localised to the photoreceptor connecting cilium, regulates rhodopsin transport to the outer segment through its effect on the turnover of actin. We set out to establish a novel model for RPGR disease to test the hypothesis that RPGR mutations lead to retinal degeneration due to a dysregulation of the actin cytoskeleton. ⋯ Wellcome Trust.
