Hospital-acquired functional decline is common in elderly patients undergoing cardiac surgery，and it is closely related to a variety of adverse outcomes. This article reviews the current situation，adverse prognosis，assessment tools，assessment timing and influencing factors of hospital-acquired functional decline in elderly patients undergoing cardiac surgery，and also makes recommendations for further improvement of hospital-acquired functional decline，in order to provide a reference for clinical medical and nursing staff to explore suitable assessment tools，early identify the risk of hospital-acquired functional decline in elderly patients undergoing cardiac surgery and formulate personalized rehabilitation interventions.

Objective To search,evaluate and integrate the relevant evidence on the prevention and management of port-related venous thromboembolism（VTE） in cancer patients,and to provide references for clinical practice. Methods We searched CNKI,the BMJ Best Practice,UpToDate,Cochrane Library,JBI Database,CINAHL,Embase,PubMed,China Guideline Clearinghouse（CGC）,Scottish Interhospital Guidelines Network（SIGN）,National Guideline Clearinghouse（NGC）,American Intravenous Nurses Society（INS）,National Comprehensive Cancer Network（NCCN）,American Society of Clinical Oncology（ASCO）,European Society for Medical Oncology（ESMO）,and Registered Nurses’ Association of Ontario （RNAO） for relevant guidelines,systematic reviews,evidence summaries,recommended practices,and expert consensuses. The retrieval period is from the inception of databases to March 10,2021. Results A total of 12 articles were enrolled,including 4 clinical practice guidelines,5 systematic reviews,1 evidence summary and 2 expert consensuses. Totally 30 pieces of best evidence were summarized from 6 aspects,namely VTE risk assessment,catheter placement and maintenance,screening and diagnosis,prevention,management and treatment and health education. Conclusion This study summarized the best evidence on the prevention and management of port-related VTE in cancer patients. Nurses and nursing managers can select and apply the evidence according to clinical situation and patients’ wishes,so as to form a scientific,evidence-based,cancer port-related VTE prevention and management scheme,and improve nursing quality.

Objective To search,evaluate and integrate the relevant evidence for sexual health management in breast cancer patients,and to provide references for clinical practice. Methods We searched CNKI,CBM,UpToDate,PubMed,Cochrane Library,Joanna Briggs Institute,CINAHL,National Guideline Clearinghouse,National Comprehensive Cancer Network,American Society of Clinical Oncology,European Society for Medical Oncology for relevant clinical decisions,guidelines,systematic reviews,evidence summaries and expert consensuses. The retrieval period is from the establishment of databases to February 10,2022. Results A total of 17 articles were enrolled,including 4 clinical decisions,5 guidelines,4 expert consensuses and 4 systematic reviews. Totally 33 pieces of best evidence were summarized from 7 aspects,namely screening and evaluation,psychological intervention,instrumental and exercise intervention,non-hormone therapy,hormone therapy,related reproduction and training and follow-up. Conclusion This study summarized the best evidence for sexual health management in breast cancer patients. In clinical practice,nurses can personalize the application of evidence according to clinical situation and patients’ wishes to improve breast cancer patients’ sexual health.

Objective To form the Chinese expert consensus on cardiac rehabilitation nursing care，so as to standardize the work related to cardiac rehabilitation nursing. Methods The first draft was initially formed，based on a comprehensive review of domestic and foreign cardiac rehabilitation guidelines，expert consensuses，systematic reviews，original research and other literature，as well as related disease diagnosis and treatment plans，management consensuses and related literature. Results The draft was thereafter reviewed by a total of 37 experts in related fields. This consensus was finalized after 3 rounds of discussions and modifications. The expert consensus covers the following 4 topics，namely the work goals of cardiac rehabilitation nursing care，the qualifications，training，core competencies and responsibilities of cardiac rehabilitation nursing care，the components of cardiac rehabilitation nursing care，and quality control of cardiac rehabilitation nursing care，and the safety management of cardiac rehabilitation patients. Conclusion The consensus was formed on the basis of comprehensive expert opinions and relevant guidelines，consensuses and clinical research on cardiac rehabilitation，which can provide guidance for medical institutions to carry out cardiac rehabilitation nursing practice.

Objective To systematically evaluate the effectiveness of whole-body vibration（WBV） training on balance ability of the elderly. Methods We searched databases including PubMed,Embase,Web of Science,CINAHL,PEDro,Cochrane Library,CBM,CNKI,Wanfang,and VIP and selected all randomized controlled trials（RCTs） that reported the effects of WBV in the elderly. Meta-analysis was performed by RevMan 5.3. The retrieval time is from the establishment of the database to March 2019. Results A total of 25 RCTs involving 1 763 old people were finally included. Meta-analysis results showed that WBV improved dynamic balance,static balance and functional balance of the elderly,and reduced the rate of falls（P<0.05）,but there was no statistically significant difference in improving the physical health and mental health of the elderly（P>0.05）. Conclusion WBV was effective in improving dynamic balance,static balance and functional balance of the elderly,as well as reducing the incidence of falls,but the effect is not significant in improving physical health and mental health.

Objective To explore the effect of virtual cognitive rehabilitation training on cognitive function and activities of daily living among breast cancer patients with cognitive impairment.Methods Eighty breast cancer patients with cognitive impairment after chemotherapy received cognitive intervention training. Before and after intervention,clinical effects of virtual cognitive rehabilitation training were evaluated by Montreal Cognitive Assessment scale,Activity of Daily Living Scale,Mini-Mental State scale,and semi-structured interviews.Results After 8-week-intervention,the scores of the Montreal Cognitive Assessment Scale increased significantly,and the difference was statistically significant （P<0.05）. After intervention,the scores of ADL were lower than those before intervention,and the difference was statistically significant （P<0.05）. All patients gave recognition of effects of virtual cognitive rehabilitation training on improving cognitive function,while they were willing to continue this training.Conclusion Virtual cognitive rehabilitation training can improve cognitive function and daily life ability of breast cancer patients with cognitive impairment after chemotherapy.
