Article Abstract
Obesity is a major risk factor for metabolic syndrome and cardiovascular disorders. Obesity related heart disease is the most serious complication of human obesity. Despite several investigations the pathophysiological mechanisms involved remain unclear. Latest studies have emphasized the importance of adipose tissue as a highly endocrine organ which releases a wide variety of biological active substances. In this context we have recently showed that adipose tissue exerts highly potent cardiodepressant activity with an acute effect directly on cardiomyocytes contraction, thus explaining the tight association between obesity and heart failure. Further experiments led to the assumption that the activity is a protein, but some well-known adipocyte-derived proteins could be excluded to be responsible for the effect on cardiomyocytes. In the present study we investigated the production/secretion of this adipocyte-derived negative inotropic activity in more detail.

Background: The effective use of combination antiretroviral therapy (ART) has significantly improved the life expectancy of people living with the human immunodeficiency virus (HIV). However, complications have shifted from opportunistic infections to issues such as drug toxicity and resistance, as well as an increase in premature cardiovascular diseases (CVD). These conditions are attributed to chronic immune activation and persistent inflammation caused by HIV, along with lipid abnormalities and insulin resistance.

Introduction: Impaired physical fitness is a possible late effect among adult survivors of childhood cancer (ASCC). Our study describes lower body muscular strength and endurance among ASCC using the 1-minute sit-to-stand (1-min STS) test, compares them with the general population, identifies risk factors, and describes changes over time.Methods: In a prospective multicenter cohort study, we invited ASCC ≥18 years of age at study, diagnosed between ages 0-20 treated in five pediatric oncology centers across Switzerland from 1976-2017 who survived ≥5 years for a 1-min STS test.
