Relationship between ventricular repolarization parameters and the inducibility of ventricular arrhythmias during electrophysiological study in patients with coronary artery disease.
Risk stratification of sudden cardiac death in patients with coronary artery disease is of great importance. We evaluated the association between ventricular repolarization and induction of malignant ventricular arrhythmias on electrophysiological study of patients with coronary artery disease. ⋯ QT interval is an independent factor associated with malignant ventricular arrhythmias in patients with coronary artery disease. The combination of ventricular dysfunction and prolonged QT interval is associated with a 5.44-fold increase of malignant ventricular arrhythmias induction. Male gender, amiodarone use, and decreased left ventricular ejection fraction are also associated with increased risk of inducibility of malignant ventricular arrhythmias on the electrophysiological study.

Aesthetic assessment of breast reconstruction in the eyes of plastic surgeons versus nonplastic physicians.
The aim of this study was to evaluate the perception of the aesthetic result of breast reconstruction surgery from the perspective of plastic surgeons compared with physicians who are not specialists in plastic surgery. ⋯ Plastic surgeons assessed the aesthetic results of breast reconstruction more positively than nonplastic physicians.

Evaluation of the Rho-kinase gene expression and polymorphisms in adult patients with acute appendicitis: a differential impact of gender.
Acute appendicitis represents one of the most common causes of acute intra-abdominal emergencies worldwide. In this case-control study, we aimed to investigate associations of Rho-kinase gene expression and polymorphisms with acute appendicitis in a Turkish population. We also aimed to study the effects of gender on these parameters. ⋯ Our data imply that Rho-kinase1 (rs35996865) and Rho-kinase2 (rs2230774) gene variants are not risk factors for the development of acute appendicitis in the Turkish population. However, increased mRNA expression of the Rho-kinase1 gene in males indicated that Rho-kinase1 is involved in the pathogenesis of acute appendicitis in a gender-specific way.

Serum Prealbumin: a potential predictor of Right Ventricular Dysfunction in patients receiving programmed hemodialysis.
Prealbumin has been a reliable marker to predict protein energy malnutrition and hypercatabolic state. In this analysis, we particularly aimed to investigate the potential association between serum prealbumin levels and right ventricular dysfunction in patients receiving programmed hemodialysis. ⋯ This study suggests that low serum prealbumin might serve as a potential predictor of right ventricular dysfunction (and its clinical consequences) in patients receiving programmed hemodialysis.

Evaluation of cytokine levels as possible predicting elements in patients with chronic lymphocytic leukemia.
This study aimed to assess the patterns of serum cytokines in chronic lymphocytic leukemia patients at baseline and post-chemotherapy and investigate their association with response to treatment and chronic lymphocytic leukemia prognosis. ⋯ Cytokines such as IL-6 and IL-10 may be considered predicting factors for chronic lymphocytic leukemia prognosis.
