Post-liver transplantation diabetes mellitus (PLTDM) develops in up to 30% of liver transplant recipients and is associated with increased risk of mortality and multiple morbid outcomes. PLTDM is a multicausal disorder, but the main risk factor is the use of immunosuppressive agents of the calcineurin inhibitor (CNI) family (tacrolimus and cyclosporine). Additional factors, such as pre-transplant overweight, nonalcoholic steatohepatitis and hepatitis C virus infection, may further increase risk of developing PLTDM. A diagnosis of PLTDM should be established only after doses of CNI and steroids are stable and the post-operative stress has been overcome. The predominant defect induced by CNI is insulin secretory dysfunction. Plasma glucose control must start immediately after the transplant procedure in order to improve long-term results for both patient and transplant. Among the better known antidiabetics, metformin and DPP-4 inhibitors have a particularly benign profile in the PLTDM context and are the preferred oral agents for long-term management. Insulin therapy is also an effective approach that addresses the prevailing pathophysiological defect of the disorder. There is still insufficient evidence about the impact of newer families of antidiabetics (GLP-1 agonists, SGLT-2 inhibitors) on PLTDM. In this review, we summarize current knowledge on the epidemiology, pathogenesis, course of disease and medical management of PLTDM.

Highlights Pneumoperitoneum is a rare cause of ACS. A defined approach has not been established. Whenever possible a minimally invasive approach should be attempted. Avoiding laparotomy may benefit certain patients. Reports are important in order to establish a treatment protocol.

Introduction: To evaluate the effect of a lipidbased formulation containing unusual polyunsaturated fatty acids, trace elements, polyphenols and plant sterols on insulin resistance and its associated disturbances among adults at risk of diabetes. Methods: This was an 8-week, three-arm, openlabel randomized clinical trial. We studied individuals aged C 18 years old with diabetes risk given by a body mass index C 25 kg/m 2 or a Enhanced Digital Features To view enhanced digital features for this article go to:

Objective To explore the influence of socioeconomic position on habitual dietary intake in Colombian cities. Design We conducted a cross-sectional, population-based study in five Colombian cities. Dietary intake was assessed with a 157-item semi-quantitative food frequency questionnaire previously developed for the Colombian population. Nutrient analysis was performed using national and international food composition tables. Socioeconomic position was assessed with two indicators: a government-defined, asset-based, household-level index called socioeconomic stratum (SES) and, among adults, highest educational level attained. Setting The five main urban centers of Colombia: Bogotá, Medellin, Barranquilla, Cali and Bucaramanga. Participants Probabilistic, multistage sample of 1865 participants (n=1491 for analyses on education). Results For both sexes, increasing SES was associated with a lower consumption of energy (p-trend <0.001 in both sexes), carbohydrates (p-trend ˂0.001 in both sexes), sodium (p-trend=0.005 in males, <0.001 in females), saturated fatty acids (p-trend <0.001 in both sexes) and among females, cholesterol (p-trend=0.002). More educated men consumed significantly less energy and carbohydrates (p-trend=0.036 and ˂0.001, respectively). Among men, intake of trans fats increased monotonically with educational level, being 21% higher among college graduates relative to those with only elementary education (p-trend=0.023). Among women, higher educational level was associated with higher MUFA intake (p-trend=0.027). Conclusions SES and educational level are strong correlates of the usual diet of urban Colombians. Economically deprived and less educated segments of society display dietary habits that make them vulnerable to chronic diseases and should be the primary target of public health nutrition policies.
