  • 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.

  • Association between acid suppressive drug use and fracture risk in children and adolescents: a meta-analysis

    ObjectiveTo systematically review the association between acid suppressive drug use and fracture risk in children and adolescents. MethodsThe PubMed, Web of Science, EMbase, Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect observational studies on the association between acid suppressive drug use and fracture risk in children and adolescents from inception to October 1, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using R4.1.2 software. ResultsA total of 6 studies involving 1 886 423 children and adolescents were included. Meta-analysis results showed that the use of proton pump inhibitors (PPIs) increased the risk of fracture (RR=1.19, 95%CI 1.10 to 1.29, P<0.01), whereas the use of histamine H2 receptor antagonists (H2RAs) did not increase the risk of fracture (P>0.05). Subgroup analysis showed that PPIs use increased risk of fracture in the lower limb and other sites (P<0.05). ConclusionCurrent evidence shows that PPIs can increase fracture risk in children and adolescents, but no association has been found between the use of H2RAs and increased fracture risk in this group. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
