Cohort profile: golestan hepatitis B cohort study- a prospective long term study in northern iran ​.

Hepatitis B virus (HBV) infection is the most common cause of end stage liver disease in Iran and in Golestan province. Large-scale population-based prospective cohort studies with long term follow-up are the method of choice to accurately understand the natural course of HBV infection. To date, several studies of HBV epidemiology, natural history, progression to cirrhosis and association with HCC have been reported from other countries.

Polypill for the prevention of cardiovascular disease (PolyIran): study design and rationale for a pragmatic cluster randomized controlled trial.

Background: The complexity of treatment regimens, costs and pill burden decrease the medication adherence and contribute to shortfall in cardiovascular preventive drug coverage. The polypill, a fixed dose combination pill of established drugs, is expected to increase adherence and reduce the costs whilst preventing major cardiovascular events (MCVE).

Design And Methods: The PolyIran trial is a pragmatic cluster randomized trial nested within the Golestan Cohort Study (GCS).

Liver transplant patients have a risk of progression similar to that of sporadic patients with branch duct intraductal papillary mucinous neoplasms.

Intraductal papillary mucinous neoplasms (IPMNs) have malignant potential and can progress from low- to high-grade dysplasia to invasive adenocarcinoma. The management of patients with IPMNs is dependent on their risk of malignant progression, with surgical resection recommended for patients with branch-duct IPMN (BD-IPMN) who develop high-risk features. There is increasing evidence that liver transplant (LT) patients are at increased risk of extrahepatic malignancy.

Impact of microscopic duodenitis on symptomatic response to Helicobacter pylori eradication in functional dyspepsia.

Na(+)-H+ exchange inhibition attenuates ischemic injury in rat random pattern skin flap: the role of mitochondrial ATP-sensitive potassium channels.

Necrosis of distal portion of skin flaps due to ischemia still remains a problem in plastic surgery. Following ischemia, a cascade of deleterious events including over-activity of Na(+)-H(+) Exchanger (NHE) takes place. In present study we evaluated the effect of the potent NHE inhibitor, 5-(N-ethyl-N-isopropyl) amiloride (EIPA) on ischemic tissue injury in a skin flap model, and investigated the role of mitochondrial ATP-sensitive K(+) channels (K(ATP)) in this phenomenon.

Seroprevalence of hepatitis B surface antigen and anti hepatitis C antibody in zahedan city, iran: a population-based study.

Background: There have been studies regarding the prevalence of hepatitis B surface antigen (HBsAg) and anti-hepatitis C antibody (HCVAb) in Iran. However, the majority of these have reported a variety of rates, depending on their study population, which limits the generalizability of their results to the general population. On the other hand, cultural diversity in the different provinces of Iran also necessitates the performing separate population-based studies in the various regions.
