Clinical Manifestations and Diagnosis of Nonalcoholic Fatty Liver Disease.

Background & Objective: Nonalcoholic fatty liver diseases (NAFLD) is the major cause of hepatocellular carcinoma and increases the risk of mortality. Understanding the trends of its clinical and biochemical changes is essential to identify patients with NAFLD that are at the greatest risk of nonalcoholic steatohepatitis (NASH) and cirrhosis in Iran.

Methods: Patients with NAFLD confirmed by ultrasonography were enrolled into the current study.

Expression of Efflux Pumps and Fatty Acid Activator One Genes in Azole Resistant Candida Glabrata Isolated From Immunocompromised Patients.

Acquired azole resistance in opportunistic fungi causes severe clinical problems in immunosuppressed individuals. This study investigated the molecular mechanisms of azole resistance in clinical isolates of Candida glabrata. Six unmatched strains were obtained from an epidemiological survey of candidiasis in immunocompromised hosts that included azole and amphotericin B susceptible and azole resistant clinical isolates.

Accuracy of endoscopic ultrasonography for determination of tumor invasion depth in gastric cancer.

Background: Gastric cancer (GC) is one the common lethal cancers in Iran. Detection of GC in the early stages would assesses to improve the survival of patients. In this study, we attempt to evaluate the accuracy of EUS in detection depth of invasion of GC among Iranian Patients.

Assessing validity and reliability of Dundee ready educational environment measure (DREEM) in Iran.

Background: If an institute is looking for improvement of its learning environment, a reliable and valid assessment tool is needed for measurement of the educational environment .The Dundee Ready Educational Environment Measure (DREEM) has been used in various studies to evaluate the educational environment. However, psychometric evaluations of the instrument seem necessary, for all known versions of the instrument.

Prevalence of colorectal adenoma in an average-risk population aged 40-50 versus 50-60 years.

According to current guidelines, screening colonoscopy begins at 50 years for the average-risk population, although there are not enough data on the incidence of precancerous lesions of individuals in the preceding decades. To evaluate the prevalence of colorectal polyps including potentially premalignant lesions in asymptomatic, average-risk individuals aged 40-49 versus 50-59 years, we offered total colonoscopy screening to individuals without any lower gastrointestinal symptoms. The primary end point was the prevalence of colorectal adenoma in two age groups.
