Hepatitis B reactivation in hepatitis B and C coinfected patients treated with antiviral agents: A systematic review and meta-analysis.

Unlabelled: There is an increased awareness of hepatitis B (HBV) reactivation in chronic hepatitis C (CHC) patients coinfected with HBV treated with pan-oral direct-acting antiviral agents (DAAs). We performed a systematic review and meta-analysis to compare the rate of HBV reactivation in CHC patients coinfected with overt HBV (hepatitis B surface antigen [HBsAg] positive) and occult HBV (HBsAg negative with positive HBV DNA) infection separately, treated with interferon (IFN)-based therapy to those with pan-oral DAAs. The primary outcome was HBV reactivation, and the secondary outcomes included hepatitis due to HBV reactivation, sustained virologic response (SVR) for CHC, loss of HBV DNA and HBsAg seroclearance.

Orally Administered Trimethoprim-Sulfamethoxazole and Metronidazole as Infection Prophylaxis in Elective Colorectal Surgery.

Background: This randomized clinical trial evaluated orally administered trimethoprim-sulfamethoxazole and metronidazole (TSM) in elective colorectal surgery as prophylactic for post-operative surgical site infections (SSI).

Methods: Patients undergoing elective colorectal resection were evaluated for inclusion. Randomized subjects received either orally administered TSM or intravenously administered cefuroxime and metronidazole (control group, CXM).

Effects of proton-pump inhibitors on functional dyspepsia: a meta-analysis of randomized placebo-controlled trials.

Background & Aims: The aim of this study was to assess systematically the efficacy of proton pump inhibitors (PPIs) in the treatment of functional dyspepsia compared with placebo and to determine if any difference in the response exists between symptom subgroups of functional dyspepsia.

Methods: A literature search was performed through September 2005 in PubMed, Medline, Embase, CINAHL, and Cochrane databases to include randomized, double-blind, placebo-controlled trials evaluating the efficacy of PPIs for the treatment of functional dyspepsia. Relative risk (RR) and relative risk reduction (RRR) and 95% confidence intervals (CI) were calculated under a random-effects model.

The association between seated immobility and local lower-limb venous coagulability in healthy adult volunteers: a simulation of prolonged travel immobility.

This is the first study to examine the hypothesis that prolonged sitting is associated with procoagulant changes in the local lower-limb venous system. A comparison was made with upper-limb venous changes. Changes in markers of thrombin generation, fibrinolysis, endothelial perturbation and haemoconcentration were analysed as 10 healthy adult male participants sat for 8 h.
