Previous studies have found obesity to be associated with adverse events, but others have found no association. The aim of this study was to determine whether increasing body mass index (BMI) is an independent risk factor for development of major postoperative complications. This was a multicentre prospective cohort study across the UK and Republic of Ireland. Consecutive patients undergoing elective or emergency gastrointestinal surgery over a 4-month interval (October-December 2014) were eligible for inclusion. The primary outcome was the 30-day major complication rate (Clavien-Dindo grade III-V). BMI was grouped according to the World Health Organization classification. Multilevel logistic regression models were used to adjust for patient, operative and hospital-level effects, creating odds ratios (ORs) and 95 per cent confidence intervals (c.i.). Of 7965 patients, 2545 (32·0 per...

Although this property represents incredible and unique communication opportunities, it also brings along important challenges. Often, content which constitutes hate speech, abuse, harmful intent proliferates online platforms. Since problematic content reduces the health of a platform and negatively affects user experience, communities have terms of usage or community norms in place, which when violated by a user, leads to moderation action on that user by the platform. Unfortunately, the scale at which these platforms operate makes manual content moderation near impossible, leading to the need for automated or semi-automated content moderation systems. For understanding the prevalence and impact of such content, there are multiple methods including supervised machine learning and deep learning models. Despite the vast interest in the theme and wide popularity of some methods, it is uncl...
