The lack of physical activity and the adoption of poor nutritional habits is the major cause of the obesity epidemic that is currently sweeping the world. The expansion of adipose tissue mass, especially of the visceral adipose tissue depot, is observed in the vast majority of individuals carrying the clinical features of the metabolic syndrome, an important (and reversible) risk factor of type 2 diabetes and cardiovascular disease. ⋯ However, an elevated waist circumference might also be the result of an increased 'cardioprotective' subcutaneous adipose tissue mass. We have proposed that the measurement of plasma triglycerides along with waist circumference, the so-called 'hypertriglyceridemic waist' might better quantify visceral obesity and its health hazards than waist circumference alone. "Hypertriglyceridemic waist" is thought to represent an altered, dysfunctional, and highly lipolytic adipose tissue that is a major culprit abnormality behind the metabolic syndrome and associated cardiometabolic risk, independently from classical cardiovascular disease risk factors such as age, sex, and plasma low density lipoprotein (LDL) cholesterol levels.

Cutaneous drug reactions are the most common type of adverse drug reaction. These reactions, ranging from simple pruritic eruptions to potentially life-threatening events, are a significant cause of iatrogenic morbidity and mortality. ⋯ Nevertheless, despite being a problem that is global in scope, government and health care agencies worldwide have yet to find a consensus on either diagnostic criteria or therapy for this disorder. Here, we provide the internist and emergency room physician with a brief review the SJS literature and summarize the latest recommended interventions with the hope of improving early recognition of this disease and prevention of permanent sequelae and mortality that frequently complicate SJS.

A mild increase in liver enzyme levels is sometimes observed in patients with diabetic ketosis or ketoacidosis. The aim of the present study was to assess the cause and prevalence of the elevation of liver transaminase levels in fulminant and acute-onset type 1 diabetic patients experiencing diabetic ketosis or ketoacidosis. ⋯ High blood glucose and fatty liver may influence the elevation of liver transaminase levels during the treatment of new-onset type 1 diabetes.

Strengthening causal inference in cardiovascular epidemiology through Mendelian randomization.
Observational studies have contributed in a major way to understanding modifiable determinants of cardiovascular disease risk, but several examples exist of factors that were identified in observational studies as potentially protecting against coronary heart disease, that in randomized controlled trials had no such effect. The likely reason for misleading findings from observational epidemiological studies is that associations are influenced by confounding, bias, and reverse causation--where disease influences a risk factor, rather than vice versa. Mendelian randomization utilizes genetic variants that serve as proxy measures for modifiable risk factors to allow estimation of the causal influence of the modifiable risk factor in question. We present examples of the use of the Mendelian randomization approach and discuss both the limitations and potentials of this strategy.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only proven curative therapy for chronic myeloid leukemia (CML), but lack of human leukocyte antigen (HLA)-matched sibling or unrelated donors has restricted its application. Recently, we developed an effective method for haploidentical allo-HSCT achieving comparable outcomes to HLA-identical transplantation. ⋯ For patients lacking an HLA-identical related donor, haploidentical relatives are alternative HSCT donors.
