  • Efficacy of living preparation of lactobacillus in treatment of bacterial vaginosis during pregnancy: a meta-analysis

    ObjectivesTo systematically review the efficacy of living preparation of lactobacillus for bacterial vaginosis (BV) during pregnancy.MethodsPubMed, Web of Science, Medline (OVID), CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect randomized controlled trials (RCTs) of living preparation of lactobacillus for BV during pregnancy from inception to September 30th, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 21 RCTs involving 2 930 patients were included. The results of meta-analysis indicated that: living preparation of lactobacillus was superior to metronidazole in effective rate (RR=1.05, 95%CI 1.02 to 1.07, P=0.000 4), premature delivery rate (RR=0.49, 95%CI 0.32 to 0.73, P=0.000 4), premature rupture of membrane rate (RR=0.54, 95%CI 0.38 to 0.77, P=0.000 7), infant of low-birth weight rate (RR=0.45, 95%CI 0.22 to 0.94, P=0.03) and puerperal infection rate (RR=0.60, 95%CI 0.39 to 0.94, P=0.03).ConclusionsThe current evidence shows that, living preparation of lactobacillus is superior to metronidazole for BV during pregnancy, and the incidence of adverse pregnancy outcomes (preterm delivery, premature rupture of membranes, low birth weight, puerperal infection) after treatment is lower. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.

  • Association of micronucleus and polycystic ovary syndrome: a meta-analysis

    ObjectiveTo systematically review the association of micronucleus and polycystic ovary syndrome (PCOS).MethodsPubMed, OVID, Elsevier, CNKI, WanFang Data and CBM databases were electronically searched to collect case-control studies on the association of micronucleus and PCOS. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 5 case-control studies were included, in which 170 patients were in the case group and 148 in the control group. The results of meta-analysis showed: there were significant differences between the two groups for micronucleus frequency (MD=2.02%, 95%CI 1.63% to 2.41%, P<0.000 01) in peripheral blood lymphocytes and micro nucleated cells frequency (MD=2.43%, 95%CI 0.10% to 4.76%, P=0.04) in oral epithelial cells.ConclusionThe current evidence shows that micronucleus is associated with PCOS. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
