ObjectiveTo systematically review the effectiveness of breastfeeding duration and intensity in reducing the risk of overweight or obesity among offspring exposed to intrauterine hyperglycemia. MethodsThe PubMed, EMbase, Web of Science, CBM, WanFang Data, CNKI and VIP databases were electronically searched to collect observational studies on the associations of breastfeeding with the risk of overweight or obesity among offspring exposed to intrauterine hyperglycemia from inception to September 25th, 2021. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Stata 16.0 software was used for the meta-analysis. ResultsA total of 12 657 participants from 13 observational studies were included. The results of meta-analysis showed that breastfeeding could reduce the risk of overweight or obesity among offspring exposed to intrauterine hyperglycemia (OR=0.67, 95%CI 0.53 to 0.84, P=0.001). Subgroup analysis revealed a protective effect of breastfeeding for both 1-6 months (OR=0.53, 95%CI 0.37 to 0.75, P<0.001) and ≥6 months (OR=0.56, 95%CI 0.46 to 0.69, P<0.001); however, breastfeeding shorter than one month was suggested to increase the risk of overweight or obesity (OR=2.15, 95%CI 1.41 to 3.27, P<0.001). ConclusionAvailable evidence suggests that breastfeeding for more than one month is effective in reducing the risk of overweight or obesity in offspring exposed to intrauterine hyperglycemia, and women with hyperglycemia should be encouraged to breastfeed their offspring for at least 1 month to achieve the effect. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To evaluate the role of systematic lymphadenectomy (SL) vs. unsystematic lymphadenectomy (USL) for improving overall survival (OS) in epithelial ovarian cancer (EOC). Methods The databases such as PubMed, EMbase, The Cochrane Library, Evidence-Based Medicine Reviews (EBMR), CBM, CNKI and VIP were searched between January 1, 1995 and December 31, 2010, the randomized controlled trials (RCTs) and observational studies on SL vs. USL in treating EOC were included. Based on Cochrane handbook, the data were extracted, the methodological quality was assessed, and then meta-analyses were conducted by using RevMan 5.0 software. Results The total 13 studies involving 22 796 patients were included, including 5 420 patients in the SL group, and the other 17 376 patients in the USL group. Two of the 13 studies were RCTs, and the other 11 were observational studies (including 2 studies retrieved from SEER data). The analyses on 2 RCTs showed that compared with USL, a) SL could not improve 5-PFS (OR=0.70, 95%CI 0.40 to 1.22, P=0.21) in early-stage EOC (FIGO I to II), but it did improve 5-PFS (OR=0.62, 95%CI 0.40 to 0.96, P=0.03) in advanced-stage EOC (FIGO III to IV); b) SL could not improve 5-OS in both early-stage EOC (OR=0.84; 95%CI 0.44 to1.58, P=0.58) and advanced-stage EOC (OR=0.93, 95%CI 0.64 to 1.37, P=0.73); and c) SL could not improve 5-OS in both early-stage (OR=0.84, 95%CI 0.44 to 1.58, P=0.58) and advanced-stage (OR=0.93, 95%CI 0.64 to 1.37, P=0.73) of EOC patients who had optimal tumor dubulking surgery. The analyses on observational studies showed that compared with USL, a) SL could not improve 5-PFS in both early-stage EOC (OR=0.38, 95%CI 0.08 to 1.74, P=0.21) and advanced-stage (OR=2.88, 95%CI 0.95 to 8.72, P=0.06) EOC; b) Whether SEER impacts were excluded or not, SL did improve 5-OS in both early-stage EOC (OR=0.54, 95%CI 0.46 to 0.63, Plt;0.000 01) and advanced-stage (OR=0.47, 95%CI 0.43 to 0.52, Plt;0.000 01) EOC; and c) For EOC patients who had optimal tumor dubulking surgery, SL could not improve 5-OS in early-stage (OR=0.32, 95% CI 0.02 to 6.19, P=0.45), but it did improve 5-OS in advanced-stage (OR=0.53, 95%CI 0.32 to 0.88, P=0.01). Conclusion These findings suggest that maybe SL can improve 5-PFS and 5-OS in EOC. However, the efficacy of SL on 5-PFS and 5-OS is still undetermined, so more relevant studies are required for further investigating the role of SL in EOC.

Nonrandomized studies are an important method for evaluating the effects of exposures (including environmental, occupational, and behavioral exposures) on human health. Risk of bias in nonrandomized studies of exposures (ROBINS-E) is used to evaluate the risk of bias in natural or occupational exposure observational studies. This paper introduces the main contents of ROBINS-E 2022, including backgrounds, seven domains, signal questions and the operation process.
