Is body mass index directly associated with biomarkers of angiogenesis and inflammation in children and adolescents?
Increasing BMI was associated with plasma levels hs-CRP and VEGF, which are involved in the initiation and progression of atherosclerosis. The lack of association between BMI and markers of cardiac damage (hs-TnT) or ventricular volume overload (NT-proBNP) suggest that atherosclerotic risk may still at a preclinical stage in this population of obese but otherwise healthy young individuals. Collectively, this suite of biomarkers could provide mechanistic insights into the physiopathologic progression of cardiovascular risk associated with childhood obesity.
These data suggest that combined moderate to high dose khat and ethanol co-dependence produce a greater deleterious CNS effect than either drug alone. Future studies will address neurochemical effects, in addition to neuroadaptations, resulting from coabuse of these drugs.
