Objective To systematically search,evaluate,and summarize the evidence for risk management of breast and ovarian cancers in carriers of breast cancer susceptibility gene 1/2(BRCA1/2)mutations.Methods A systematic search was conducted in BMJ Best Practice,UpTo-Date,the National Guideline Clearinghouse(NGC),the National Institute for Health and Care Ex-cellence(NICE),the Scottish Intercollegiate Guidelines Network(SIGN),the Guidelines Interna-tional Network(GIN),the New Zealand Guidelines Group(NZGG),the Canadian Medical Associa-tion Infobase(CMA InfoBase),the Registered Nurses' Association of Ontario(RNAO),the National Comprehensive Cancer Network(NCCN),Cancer Care Ontario(CCO),the Medlive website,the American Society of Clinical Oncology(ASCO),the European Society for Medical Oncology(ESMO),the American Cancer Society(ACS),the American College of Obstetricians and Gynecologists(ACOG),the Joanna Briggs Institute(JBI),the Cochrane Library,PubMed,Web of Science,Em-base,CINAHL,ProQuest,ClinicalTrials.gov,China National Knowledge Infrastructure,Wanfang Data,VIP Database,and SinoMed for evidence related to risk management of breast and ovarian canc-ers in BRCA1/2 mutation carriers,including clinical decisions,guidelines,systematic reviews,expert consensus,and evidence summaries.The search period was from the inception of each database to September 20,2024.Results A total of 14 articles were included,comprising 1 clinical decision,8 guidelines,and 5 expert consensus documents.Based on five themes-risk assessment,risk moni-toring,risk-reducing surgery,pharmacologic prevention,and health guidance,a total of 24 pieces of evidence were summarized.Conclusion The evidence summarization process in this study is standardized,and the summarized evidence is relatively comprehensive.Healthcare professionals should comprehensively consider patients' individual characteristics,family history,personal prefer-ences,and the accessibility of healthcare resources to achieve effective prevention and control of he-reditary tumor risks.

Objective:To systematically evaluate the qualitative research on the practical experience of hospice care among medical staff in nursing homes, and to provide a reference basis for the implementation of hospice care services in nursing homes.Methods:The qualitative research on the practical experience of hospice care among medical staff in nursing homes was searched from databases including the Web of Science, PubMed, Cochrane Library, Embase, CINAHL, China National Knowledge Infrastructure, China Biology Medicine disc, Wanfang Data and VIP Database. The retrieval period was from the establishment of the database to March 21, 2024. The quality evaluation standards for qualitative research of the Australian Joanna Briggs Institute Evidence-Based Health Care Center were used to evaluate the quality of the literature. The results were integrated by the method of aggregative integration.Results:A total of 15 studies were included, and 47 clear research results were extracted, summarized into 11 categories, and 4 integrated results were obtained: the palliative care work responsibilities of medical staff; the emotional experience of medical staff in practice; coping with negative experience and gaining personal growth;the practical dilemmas faced by nursing homes when implementing hospice care.Conclusions:Nursing homes face multiple obstacles and challenges in the process of providing hospice care services. It is recommended that future research should focus on improving the policy system of hospice care in nursing homes, building a support system for hospice care services, and promoting the development and practice of death literacy among the public, so as to promote the healthy and long-term development of hospice care services in nursing homes.
