Objective To explore the facilitators and barriers of palliative care volunteering,and to provide references for further advancement of palliative care volunteering.Methods Purposeful sampling was used to select 12 volunteers from a palliative care ward in Hangzhou,Zhejiang Province,between April and September 2024.Semi-structured interviews were conducted,and directed content analysis was applied to organize and analyze the data,followed by theme analysis.Results Facilitators and barriers for volunteers' participation in palliative care volunteering were extracted.The 5 sub-themes of facilitators include motivating factors and perceived benefits,support and collaboration among volunteers,professional training and healthcare recognition,increased social awareness and public acceptance,and government support and institutional safeguards.The 5 sub-themes of barriers include limitations in individual capacity,challenges in collaboration with patients,families and healthcare workers,inadequate management and service mechanisms,uneven development of palliative care and insufficient public attention to psychological problems,and inadequate relevant laws and incentives.Conclusion There are more factors affecting the development of palliative care volunteering,and healthcare professionals should adopt targeted strategies to promote the active participation of volunteers in order to promote the sustainable development of palliative care volunteering.

Objective:To systematically integrate the work experience of medical and nursing staff in the remote home palliative care model, so as to provide a reference for improving remote home palliative care services.Methods:Qualitative studies on medical and nursing staff providing remote home palliative care were electronically searched in PubMed, Web of Science, Embase, ProQuest, CINAHL, PsycINFO, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to April 30, 2024. Literature quality evaluation was conducted using the Joanna Briggs Institute Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The aggregative integration method was used to synthesize the findings.Results:Researchers repeatedly read, analyzed, and interpreted the 17 included literature, extracting 56 themes and summarizing eight new categories, and further synthesized three integrated results, namely, remote home palliative care provided patients with comprehensive physical, psychological, and mental care, as well as guidance and support for family members; remote home care helped to achieve full coverage of palliative care services; equipment limitations, information security risks, and incomplete processes restricted the development of remote palliative care.Conclusions:Remote home palliative care has improved patient care and family support capabilities, expanded service coverage, and promoted interdisciplinary collaboration. However, there are still issues such as equipment limitations, information security risks, and incomplete processes. Optimizing processes, improving safety mechanisms, and strengthening collaboration platforms will contribute to sustainable development.

Objective To assess the correlation between the severity of postoperative nausea and vomiting(PONV)with the quality of postoperative recovery and capacity of mobility in patients after video-assisted thoracoscopic surgery.Methods A total of 125 patients,80 males and 45 females,aged 18-64 years,BMI 18-35 kg/m2,ASA physical status Ⅰ-Ⅲ,undergoing video-assisted thoracoscopic surgery were observed.The severity of PONV was assessed using the simplified PONV impact scale day 1 after sur-gery.The patients were divided into three groups according to the severity of PONV:non-PONV group(n = 87),mild PONV group(n = 31),and moderate to severe PONV group(n = 7).The quality of recovery was assessed using the quality of recovery-15(QoR-15)on the first day after surgery,and the capacity of mobility was assessed using the 6-minute walk test(6-MWT)on the second day after surgery.The multiple linear regression model was used to analyze the correlation between the severity of PONV and quality of post-operative recovery and capacity of mobility.Results The results of the corrected multiple linear regression model showed that,compared with the patients without PONV,the QoR-15 scores of the patients with mild and moderate-severe PONV on the first day after surgery were reduced by 4.5 scores(95%CI-8.9 to-0.04 scores,P = 0.048)and 15.8 scores(95%CI-24.8 to-6.8 scores,P = 0.001),respectively.Mild(MD =-27.4 m,95%CI-70.1 to 15.4 m,P = 0.207)and moderate-severe PONV(MD =-57.0 m,95%CI-145.7 to 31.6 m,P = 0.204)were not significantly associated with 6-MWT distance shortening on the second day after surgery.Conclusion Increased PONV severity is associated with poorer recovery quality in patients undergoing pulmonary surgery.Active prevention and treatment of PONV may contribute to early recovery of patients.

BACKGROUND:Bibliometrics and visual analyses based on thematic literature are particularly important for understanding the foundation and frontiers of postmenopausal osteoporosis research. OBJECTIVE:To perform bibliometric,citation,and visualization analyses of highly cited SCI papers in postmenopausal osteoporosis research over the last 20 years. METHODS:The top 100 highly cited papers on postmenopausal osteoporosis published between 2003 and 2022 included in SCI-EXPANDED catalog of the Web of Science database were obtained for bibliometric measure and visual analysis using CiteSpace software. RESULTS AND CONCLUSION:The top 100 highly cited papers have a total of 67 377 citations in the Web of Science Core Collection,with an annual average of 49.17 citations per paper.Postmenopausal osteoporosis research primarily involves medical,engineering,biological,and multidisciplinary fields.The subcategories are dominated by endocrinology and metabolism,and medicine:internal medicine.Stable and close cooperative network relationships have been formed globally.United States,University of California System,Cummings,and Steven R are the country,research institution,and author,respectively,with the most highly-cited publications.The frontiers of postmenopausal osteoporosis research mainly include calcium and vitamin D supplementation and fracture risk,clinical studies of bisphosphonates in the treatment of postmenopausal osteoporosis,atypical femur fracture,clinical studies of new drugs and sequential treatment of postmenopausal osteoporosis,predictors of fracture risk,mid-and long-term follow-up of osteoporotic vertebral compression fractures,genetic polymorphisms and hereditary factors,formulation and updating of clinical practice guidelines for postmenopausal osteoporosis.Large cohort studies,high-quality randomized controlled trials,systematic reviews,meta-analyses,and clinical practice guidelines are the great engines that drive the development of clinical research in postmenopausal osteoporosis.We should make efforts in the above areas to improve China's international influence in the field of osteoporosis.

Objective:To investigate the treatment outcome of chemotherapy regimens containing azacitidine and mitoxantrone liposome in the treatment of angioimmunoblastic T-cell lymphoma (AITL).Methods:The clinical data of 1 AITL patient with severe clinical symptoms admitted to Weihai Municipal Hospital in July 2021 were retrospectively analyzed, and the relevant literatures were reviewed.Results:The 74-year-old male patient was presented with the manifestations of rash, lymph node enlargement, bloating and fever. He was pathologically diagnosed as AITL by lymph node biopsy. In the early stage of treatment, due to severe clinical symptoms and poor therapeutic effect, the treatment regimens were constantly adjusted. CHOPE, etoposide + chidamide + thalidomide +dexamethasone + cyclosporine, brentuximab vedotin + bendamustine + dexamethasone + cyclosporine + thalidomide +chidamide regimens were used successively, and the disease progressed after short-term complete remission. Finally complete remission was obtained again after a multi-drug combination regimens containing azacitidine and mitoxantrone liposome, following the maintenance treatment of azacitidine combined with chidamide, and the disease condition of the patient remained stable.Conclusions:The chemotherapy regimens containing azacitidine and mitoxantrone liposome can achieve a good therapeutic effect for relapsed/refractory AITL.
