Given the increasing prevalence of diabetes and obesity worldwide, the deleterious effects of non-alcoholic fatty liver disease (NAFLD) are becoming a growing challenge for public health. NAFLD is the most common chronic liver disease in the Western world. NAFLD is closely associated with metabolic disorders, including central obesity, dyslipidaemia, hypertension, hyperglycaemia and persistent abnormalities of liver function tests.In general NAFLD is a common denominer for a broad spectrum of damage to the liver, which can be due to hepatocyte injury, inflammatory processes and fibrosis. This is normally seen on liver biopsy and can range from milder forms (steatosis) to the more severe forms (non-alcoholic steatohepatitis (NASH), advanced fibrosis, cirrhosis and liver failure). In these patients, advanced fibrosis is the major predictor of morbidity and liver-related mortality, and an accurate diagnosis of NASH and NAFLD is mandatory. Histologic evaluation with liver biopsy remains the gold standard to diagnose NAFLD. Diagnosis of NAFLD is defined as presence of hepatic steatosis, ballooning and lobular inflammation with or without fibrosis. Weight loss, dietary modification, and the treatment of underlying metabolic syndrome remain the mainstays of therapy once the diagnosis is established. Dietary recommendations and lifestyle interventions, weight loss, and the treatment of underlying metabolic syndrome remain the mainstays of therapy once the diagnosis is established with promising results but are difficult to maintain. Pioglitazone and vitamin E are recommended by guidelines in selected patients. This review gives an overview of NAFLD and its treatment options.

ObjectiveSurgery remains an inherently male-dominated profession. The aim of this study was to survey women working within the discipline, to understand their current perceptions, providing insight into their practical day-to-day lives, supporting an action-oriented change.Design and settingThe link to a confidential, online survey was distributed through the Association of Surgeons of Great Britain and Ireland (ASGBI) social media platforms on Facebook and Twitter over a 2-week period in October 2017.ParticipantsWomen working in surgical specialties and actively responding to the link shared through the ASGBI social media platforms. No patients were involved in the study.Primary and secondary outcome measuresData were analysed through a mixed-methods approach. The quantitative data were analysed through descriptive statistics and qualitative analysis was undertaken using a constant comparative analysis of the participants’ comments, to identify salient patterns (themes).ResultsA total of 81 female participants replied (42% response rate based on the Facebook group members), with 88% (n=71) perceiving surgery as a male-dominated field. Over half had experienced discrimination (59%, n=47), while 22% (n=18) perceived a ‘glass ceiling’ in surgical training. Orthopaedics was reported as the most sexist surgical specialty by 53% (n=43). Accounts of gendered language in the workplace were reported by 59% (n=47), with 32% (n=25) of surveys participants having used it. Overall, a lack of formal mentorship, inflexibility towards part-time careers, gender stereotypes and poor work–life balance were the main perceived barriers for women in surgical careers.ConclusionThese findings highlight the implicit nature of the perceived discrimination that women report in their surgical careers. The ASGBI acknowledges these perceptual issues and relative implications as the first of many steps to create an action-oriented change by allowing all staff, regardless of gender, to reflect on their own behaviour, perceptions and the culture in which they work.

There is currently no consensus on the combined length of small bowel that should be bypassed as biliopancreatic or alimentary limb for optimum results with Roux-en-Y gastric bypass. A number of different limb lengths exist, and there is significant variation in practice amongst surgeons. Inevitably, this means that some patients have too much small bowel bypassed and end up with malnutrition and others end up with a less effective operation. Lack of standardisation poses further problems with interpretation and comparison of scientific literature. This systematic review concludes that a range of 100-200 cm for combined length of biliopancreatic or alimentary limb gives optimum results with Roux-en-Y gastric bypass in most patients.
