Overweight children often become obese adults. The main purpose of this study was to define the risk of teenage obesity as a predictor of adulthood obesity in an under-studied and urban population. A secondary aim was to determine whether gender had an effect on the predictive value of teenage obesity. The final goal was to examine the influence of dietary habits on obesity. ⋯ The results of this study provide evidence that high BMI at age 18 is strongly correlated with adulthood obesity, much more so with women than men. Eating habits did not have an impact, suggesting that obesity may be the result of a combination of factors yet to be clearly defined.

Nonalcoholic fatty liver disease (NAFLD) is associated with both dyslipidemia and increased risk for cardiovascular disease. Despite the indication to treat in patients affected by both dyslipidemia and NAFLD, an undertreatment in statin therapy due to the potential liver damage is frequently observed. We sought to evaluate retrospectively the impact of statin on the lipid profile and on the achievement of low-density lipoprotein (LDL) cholesterol targets in relation to the National Cholesterol Education Program--Adult Treatment Panel III-cardiovascular risk in dyslipidemic patients presenting with a clinical--diagnosis of NAFLD and elevated liver enzymes before statin prescription. As a secondary endpoint, the authors investigated whether statin could be associated with changes of liver enzymes. ⋯ Statin treatment was effective (without changes in liver enzymes) in patients with dyslipidemia and NAFLD and therefore, affected by a profound alteration in lipoprotein metabolism. The number of patients achieving LDL target was related to the Adult Treatment Panel III risk classification, being higher in patients with lower risk.

Whether secondary thrombocytosis is a distinguishing clinical biomarker of various diseases, and whether it is an independent predictor of short-term outcome of admitted medical patients is unknown and has never been examined. ⋯ Thrombocytosis is not a simple marker of inflammation. Its presence warrants thorough investigation for the presence of severe underlying disease, mostly complicated pyogenic infections, inflammatory rheumatic diseases and malignancy. Moreover, thrombocytosis is a marker for major complications and is an independent predictor of mortality in admitted medical patients.

Transforming growth factor beta 1 (TGF-β1) gene plays an important role in acute myocardial infarction (AMI); however, little is known about the relation of variations within the gene and risk of cardiovascular diseases. In this study, the authors evaluated the influence of TGF-β1 polymorphisms on the onset and progression of AMI in Iranian patients comparing with healthy individuals. ⋯ Our results confirmed the association between the TGF-β1 polymorphisms and risk of AMI, which suggest that genetic polymorphisms in TGF-β1 might be helpful for determining susceptibility to AMI in Iranian patients. There are also significant relationship between serum TGF-β1 and occurrence of AMI. In addition, susceptibility to AMI might be related to TGF-β1 gene expression, which affects its serum levels.

For as long as the federal regulations governing human subjects research have existed, the practice of informed consent has been attacked as culturally biased, legalistic, ritualistic and unevenly enforced. Its focus on meeting the regulatory requirements is seen as undermining a truly ethical process that produces informed and voluntary participation in medical research. ⋯ Study participants are asked to consent to future studies with unspecified aims, broad data sharing policies and ongoing uncertainties regarding confidentiality protections and the potential benefit of incidental genomic research findings. Because more research is conducted under these new conditions, the very nature of the researcher-subject relationship is shifting and will require new governance mechanisms to promote the original goals of informed consent.
