The term 'metabolically healthy obese (MHO)' is distinguished using body mass index (BMI), yet BMI is a poor index of adiposity. Some epidemiological data suggest that MHO carries a lower risk of cardiovascular disease (CVD) or mortality than being normal weight yet metabolically unhealthy. ⋯ Myocardial dysfunction appears to be related to poor metabolic health rather than simply BMI or fat mass. These data may partly explain the epidemiological evidence on CVD risk relating to the different obesity phenotypes.

Multicenter Study
Body mass index, cardiorespiratory fitness and cardiometabolic risk factors in youth from Portugal and Mozambique.
The objectives of this study are to examine differences in cardiometabolic risk indicators, as well as their prevalences, in Portuguese and Mozambican youth, and to investigate the associations between weight status and cardiorespiratory fitness levels with cardiometabolic risk. ⋯ Portuguese and Mozambican youth differ in their cardiometabolic risk profiles, body weight and cardiorespiratory fitness, favoring Portuguese. Overweight/obesity and low cardiorespiratory fitness levels are related to a worse cardiometabolic risk profile, being relevant to design public health intervention strategies to reduce excess weight and increase cardiorespiratory fitness.

The marketing authorization for the weight loss drug sibutramine was suspended in 2010 following a major trial that showed increased rates of non-fatal myocardial infarction and cerebrovascular events in patients with pre-existing cardiovascular disease. In routine clinical practice, sibutramine was already contraindicated in patients with cardiovascular disease and so the relevance of these influential clinical trial findings to the 'real World' population of patients receiving or eligible for the drug is questionable. We assessed rates of myocardial infarction and cerebrovascular events in a cohort of patients prescribed sibutramine or orlistat in the United Kingdom. ⋯ Sibutramine was associated with increased rates of acute cardiovascular events in people with pre-existing cardiovascular disease, but there was a low absolute risk in those without. Sibutramine's marketing authorization may have, therefore, been inappropriately withdrawn for people without cardiovascular disease.

Maternal overweight/obesity and depression are among the most prevalent pregnancy complications, and although individually they are associated with poor pregnancy outcomes, their combined effects are unknown. Owing to this, the objective of this study was to determine the prevalences and the individual and combined effects of depression and overweight/obesity on neonatal outcomes. ⋯ When dually present, maternal overweight/obesity and depression combined have the greatest impact on the risk of adverse neonatal outcomes. Our findings have important public health implications given the exorbitant proportions of both of these risk factors.

The obesity epidemic represents a critical disease burden with broad clinical consequences. At the same time, obesity has been linked to inferior surgical outcomes and considered a contraindication for some elective surgical procedures. ⋯ This concept provides an integrated inflammatory network based on the perception of obesity as a state of chronic low-grade inflammation. With a more detailed understanding of this dynamic network and mechanistic insights, novel treatment and management strategies may be developed with the goal to optimize surgical outcomes in obese patients.
