Single versus double-balloon catheters for the induction of labor of singleton pregnancies: a meta-analysis of randomized and quasi-randomized controlled trials.

Objective: To compare the efficacy of single- versus double-balloon catheter (SBC vs. DBC) for cervical ripening and labor induction with an unfavorable cervix.

Methods: Systematic review and meta-analysis of randomized controlled trials (RCTs) or quasi-RCTs (qRCT) regarding the use of SBC or DBC for labor induction of live singleton cephalic pregnancies (≥ 35 weeks) of any parity with an unripe cervix (Bishop score ≤ 6).

Effects of programmed exercise on depressive symptoms in midlife and older women: A meta-analysis of randomized controlled trials.

Objective: To perform a systematic review and meta-analysis to clarify the effect of programmed exercise on depressive symptoms (DSs) in midlife and older women.

Methods: We carried out a structured search of PubMed-Medline, Web of Science, Scopus, Embase, Cochrane Library and Scielo, from database inception through June 29, 2017, without language restriction. The search included the following terms: "depression", "depressive symptoms", "exercise", "physical activity", "menopause", and "randomized controlled trial" (RCTs) in midlife and older women.

Endometriosis and gestational diabetes mellitus risk: a systematic review and meta-analysis.

Methods: We carried out a search of the following databases: Medline, Embase, Web of Science, Cochrane Library, Scopus, Scielo, Clinicaltrials.gov, the UK Clinical Trials Gateway, and the Australian New Zealand Clinical Trials Registry, from inception through April 28 2017, without language restrictions, in order to evaluate the effect of endometriosis over GDM risk, in women with and without endometriosis.
