Effect of body mass index on depression in a UK cohort of 363 037 obese patients: A longitudinal analysis of transition.

With obesity levels increasing, it is important to consider the mental health risks associated with this condition to optimize patient care. Links between depression and obesity have been explored, but few studies focus on the risk profiles of patients across stratified body mass index (BMI) classes above 30 kg/m . This study aims to determine the impact of BMI on depression risk in patients with obesity and to investigate trends of depression in a large cohort of British patients with BMI > 30 kg/m .

Three-dimensional printing in surgery: a review of current surgical applications.

Background: Three-dimensional printing (3DP) is gaining increasing recognition as a technique that will transform the landscape of surgical practice. It allows for the rapid conversion of anatomic images into physical objects, which are being used across a variety of surgical specialties. It has been unclear which groups are leading the way in coming up with novel ways of using the technology and what specifically the technology is being used for.

Do surgery journals insist on reporting by CONSORT and PRISMA? A follow-up survey of 'instructions to authors'.

Aims: Guidance has been published on how best to report randomised controlled trials (Consolidated Standards of Reporting Trials - CONSORT) and systematic reviews (Preferred Reporting Items for Systematic Reviews and Meta-analysis - PRISMA). In 2011, we reported a low rate of enforcement by surgery journals for submitted manuscripts to conform to these guidelines. The aim of this follow-up study is to establish whether there has been any improvement.
