Objective To systematically evaluate relevant guidelines on calories and 3 nutrients allocations during pregnancy in patients with gestational diabetes mellitus,and to compare the similarities and differences in recommendations between these guidelines.Methods Domestic and foreign guideline networks,websites of specialist associations related to diabetes,obstetrics and gynecology,as well as databases,were systematically searched from January 2010 to June 2022.There were 2 appraisers who used the Appraisal of Guidelines for Research &Evaluation Ⅱ to evaluate the quality of guidelines and then used the content analysis method to synthesize the recommendations of each guideline and compare similarities and differences.Results This study included 18 guidelines with fair overall quality(10 with grade A,2 with grade B and 6 with grade C).The guidelines provided recommendations in 5 aspects of meal allocation,calories,carbohydrates,proteins,and fats,totaling 57 recommendations.While the recommendations for meal allocation were consistent across guidelines,there were significant differences in the recommendations for calories and the 3 major nutrients.Conclusion The recommendations regarding the distribution of calories and the 3 major nutrients mostly rely on expert consensuses,with low-quality evidence but mostly strong recommendations.These guidelines exhibit significant variations from one to another.Consequently,future studies with higher quality on the distribution of calories and 3 nutrients should be conducted,and high-quality evidence-based nutrition guidelines for gestational diabetes should be developed in China.

Objective:To systematically search, evaluate, and summarize the best evidence on sexual health management for cervical cancer patients to provide evidence-based guidance for clinical practice.Methods:According to the "6S" pyramid model, a systematic search was conducted for evidence on sexual health management in cervical cancer patients, including clinical decisions, guidelines, evidence summaries, expert consensus, and systematic reviews, from domestic and international guidelines, professional association websites, and comprehensive databases. The search covered literature from the inception of the databases to November 30, 2023. Two researchers trained in evidence-based nursing independently evaluated the methodological quality of the included studies and extracted and summarized the evidence.Results:A total of 13 articles were included, consisting of 3 clinical decisions, 5 guidelines, 1 expert consensus, and 4 systematic reviews. A total of 27 pieces of evidence were extracted and summarized, covering six aspects: screening and assessment, psychological interventions, device and exercise interventions, non-hormonal interventions, hormonal interventions, and follow-up.Conclusions:The best evidence summarized in this study for sexual health management in cervical cancer patients can provide evidence-based guidance for clinical healthcare providers to standardize the sexual health management of cervical cancer patients.
