Insulin resistance and hyperandrogenism are the cardinal features of polycystic ovary syndrome (PCOS). Women with insulin receptor (INSR) mutations develop severe hyperandrogenism secondary to hyperinsulinaemia. We hypothesised that insulin might drive adipose testosterone generation from androstenedione through aldoketoredutase type 3 (AKR1C3) in women with insulin resistance. Here we assessed the effect of insulin on AKR1C3 activity in vivo and in vitro. ⋯ Wellcome Trust.

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).

Worldwide, obesity has doubled since 1980. WHO declares obesity as preventable and attributes the increase in prevalence to high consumption of energy-rich foods and decreased physical activity. Epidemiological and experimental studies suggest that parents' and grandparents' diet could also have a role. We established a model of grandparents' high-fat diet (HFD) to explore potential mechanisms. ⋯ UK Medical Research Council.

In the USA, more than 7200 new cases of anal cancer were diagnosed in 2014 with incidence rising. Concurrent chemoradiotherapy improves cancer-related outcomes but has led to an increase in acute and late adverse events. Patient-reported outcomes (PRO) are increasingly included in trials as a surrogate measure for reporting of late adverse events. This study aimed to select the most effective PRO to use in clinical research and practice for anal cancer since no questionnaire specific for anal cancer has been developed. ⋯ This abstract presents independent research funded by the National Institute for Health Research (NIHR).

The contemporary associations of type 2 diabetes with a wide range of incident cardiovascular diseases have not been compared. Previous studies have focussed on myocardial infarction and stroke, and these conditions are the usual outcomes chosen in clinical trials in type 2 diabetes, but other diseases such as heart failure and angina are also major causes of morbidity in diabetes. We aimed to study associations between type 2 diabetes and 12 initial manifestations of cardiovascular disease. ⋯ Wellcome Trust, National Institute for Health Research, UK Medical Research Council.
