Hepatitis B virus genotypes in southwest Iran: molecular, serological and clinical outcomes.

Aim: To investigate the associations of hepatitis B virus (HBV) genotype with HBeAg and anti-HBe status, alanine aminotransferase (ALT) levels and HBV-DNA detection in different groups of HBV-infected patients in southwest Iran.

Methods: A total of 89 HBsAg-positive serum samples were collected from the same number of patients. All sera were then investigated to determine HBV DNA and serological markers.

24-hour in-hospital mortality predictions in coronary artery bypass grafting patients.

Background: The purpose of this study was to determine the factors that can help predict risk of mortality in the first 24 h of coronary artery bypass grafting (CABG), because mortality within a few hours of surgery is a disastrous event for surgeons and the patient's family.

Methods: The study population consisted of 120 in-hospital mortality cases (1.07%) from 11,183 patients who underwent CABG from February 2002 to February 2006 by the same group of surgeons in a referral center.
