Global View of HIV Prevalence in Prisons: A Systematic Review and Meta-Analysis.

Background: We aimed to estimate the global prevalence of HIV, as well as cross-countries comparison in people who are in prison.

Methods: We systematically assessed published studies reporting HIV prevalence among prisoners in the world. We searched international datasets banks, including PubMed, SCOPUS, Cumulative Index to Nursing and ISI web of science along with local databases and included original articles reporting data on the prevalence of HIV from 1980 to 2017.

MDR1 gene C3435T polymorphism in chronic hepatitis C patients.

Background: MDR1 is a highly polymorphic gene that encodes P-glycoprotein (P-gp). This protein anchor to the cell membrane and transports toxins, xenobiotic, chemicals, and drugs from the intracellular to extracellular and thus protect cells. Polymorphism of the MDR1 gene seems to be effective in gene expression and response to treatment.

Determining the Role of Helicobacter pylori in Chronic Sinus Infections Using the Polymerase Chain Reaction.

Background: Helicobacter pylori are becoming increasingly recognized as a possible pathological cause of chronic rhinosinusitis (CRS).

Objectives: Considering the prevalence of CRS and its impact on quality of life, we decided to determine the role of H. pylori in chronic sinus infections by using the PCR technique.

The Prevalence Rate of Helicobacter pylori Infection in, Chronic Otitis Media With Effusion Patients.

Background: Otitis media with effusion (OME) is a common disease in children. Viral or bacterial infections, allergy, adenoids, functional abnormalities of the Eustachian tube, and gastroesophageal reflux might have a possible role in the pathogenesis of OME. However, the exact pathogenesis of OME is still unsettled.
