Objective To explore influencing factors of subsequent fracture among elderly osteoporotic patients and provide a basis for improving the management and early intervention after osteoporotic fracture.Methods A total of 14 349 elderly patients with osteoporotic fracture in 594 hospitals across 31 provinces(autonomous regions and municipalities)were selected by convenience sampling method from September to December 2023.A general information questionnaire and a clinical characteristics of fracture questionnaire were used.The univariate analysis and logistic regression were used to clarify the influencing factors and gender differences.Results A total of 11364 valid questionnaires were collected,with a valid questionnaire recovery rate of 79.20％.Gender,age,occupation,education,marital status,family history of osteoporosis,comorbid osteoarthropathies/rheumatism/ophthalmopathies,bone mineral density,risk of fall,risk of fracture grade,reasons and site for first fracture,whether to use walking aid and receive home rehabilitation guidance were associated with the occurrence of subsequent fracture.Gender comparisons found that widowhood,family history of osteoporosis,comorbid rheumatism,vertebral fracture,alcohol consumption,fall or no causative factor triggering the fracture,and educational level,home rehabilitation instruction were associated with the risk of subsequent fracture only in women(P＜0.05).Smoking was associated with the risk of subsequent fracture only in men(P＜0.05).Conclusion Osteoporotic subsequent fracture in the elderly is affected by multidimensional factors,with significant gender differences.The surveillance of key populations should be strengthened in prevention,control and intervention.

The cure rate of patients with classical Hodgkin’s lymphoma (cHL) has significantly improved and the mortality rate has decreased with the advancement of chemotherapy and radiotherapy, especially the application of combined radio-chemotherapy. However, some patients still face relapse or refractory issues, as well as the risk of death due to treatment-related adverse reaction. Treatment has fully entered the era of targeted therapy in recent years, with the deepening research on cHL. Novel drugs, represented by targeted CD30 antibody-drug conjugates and immune checkpoint inhibitors, have further improved the prognosis of patients with newly diagnosed and relapsed/refractory cHL. This study aims to determine the mechanism of achieving comprehensive optimization management of cHL in the new era of drugs, improve patient prognosis, enhance therapeutic efficacy, and reduce the occurence of adverse reactions.

Objective To investigate the current status and analyze the factors affecting the osteoporosis knowledge among orthopedic nurses,and to provide references for improving osteoporosis knowledge among orthopedic nurses.Methods We investigated 5 681 orthopedic nurses from 621 hospitals in 31 provinces(autonomous regions/municipalities)using a convenient sampling method from September 2023 to November 2023.We collected information using a general information questionnaire and osteoporosis knowledge assessment tool.We used univariate and multivariate logistic regression to identify risk factors.Results A total of 5 204 orthopedic nurses were included.The total mean score of osteoporosis knowledge assessment tool of nurses was[13.00(12.00,14.00)],and 23.48％nurses had a low level of osteoporosis awareness.Logistic regression analysis showed that the age,title and position of the nurses,location of the hospital,the level of the hospital,whether to conduct the fracture liaison service/to set up the refracture prevention team,whether to use calcium tablets/vitamin D,whether to carry out anti-osteoporosis drug therapy,and whether to conduct topical lectures on osteoporosis or secondary fractures,were the factors that affected orthopedic nurses'knowledge of osteoporosis(P＜0.05).Conclusion The osteoporosis knowledge of orthopedic nurses needs to be improved.Nursing managers should carry out personalized interventions from both hospital and nurse levels to improve the osteoporosis knowledge of orthopedic nurses in our country.

Objective To assess the level of knowledge and influencing factors related to osteoporosis in elderly patients with osteoporotic vertebral fractures after surgery in China,providing a basis for improving their under-standing.Methods A total of 5 955 elderly patients with osteoporotic vertebral fractures in 31 provinces(au-tonomous regions and municipalities)were selected as survey subjects from September to November 2023.A gener-al information questionnaire and an osteoporosis knowledge assessment tool were used for a cross-sectional survey.The univariate analysis and logistic regression were used to analyze the influencing factors.Results 5 248 valid questionnaires were collected,and the effective questionnaire recovery rate was 88.13％.The score of osteoporosis knowledge assessment tool of elderly patients with osteoporotic vertebral fractures after surgery was 11.00(7.00,13.00).70.03％of the patients had poor knowledge of osteoporosis.The location of the hospital(eastern re-gion hospitals),presence of tumors,past surgical history,admission for falls,diagnosis of severe osteoporosis,postop-erative complications,use of walking aids,use of anti-osteoporosis drugs,osteoporosis health education,fall prevention health education,and health education forms(video,telephone,manual,and WeChat)were the influencing factors of osteoporosis knowledge in elderly patients with osteoporotic vertebral fractures after surgery(P＜0.05).Conclusion The osteoporosis knowledge of elderly patients with osteoporotic vertebral fractures after surgery needs to be im-proved.To help the secondary prevention of osteoporosis,the standardized osteoporosis health education should be strengthened,and attention should be paid to key groups.

Objective To examine the current state of care services for geriatric osteoporotic fractures in Chinese hospitals and to provide a basis for the improvement of these services and the formulation of related policies.Methods In September to November 2023,a stratified convenience sampling method was used to investigate the implementation of care services for elderly patients with osteoporotic fractures in 621 hospitals across 31 provinces(autonomous regions and municipalities)in China.A self-designed questionnaire was utilized for this purpose.Results A total of 621 hospitals participated in the survey,with 432(69.57%)tertiary hospitals and 189(30.43%)secondary hospitals.Over 95%of hospitals provided health education on diet,medication,fall prevention,and early functional exercise for elderly fracture patients.Less than 80%of hospitals provide specialized training on osteoporosis treatment and secondary fracture prevention for medical staff.Only 263 hospitals(42.35%)routinely conduct bone density tests for patients over 50 years old with fractures,while 221 hospitals(35.59%)routinely conduct bone metabolic biochemical tests for such patients.Less than 50%of hospitals provide specialized services,such as geriatric osteoporotic fracture clinics,for elderly patients with osteoporotic fractures.Additionally,39.77%of hospital departments have not developed postoperative care plans for elderly patients with osteoporotic fractures.The lack of specialized care teams(91.63%),insufficient investment in care resources(88.08%),and the absence of policy support(77.45%)are identified as the primary factors impeding the provision of care services for elderly patients with osteoporotic fractures in hospitals.Although some care services in tertiary hospitals are superior to those in secondary hospitals(P<0.05),they are still far from adequate.Conclusion The development of care services for elderly patients with osteoporotic fractures in Chinese hospitals needs improvement.It is recommended to further standardize and enhance the content and methods of health education,intensify clinical assessments related to osteoporosis in elderly fracture patients,improve the professional care capabilities of medical staff,and at the same time,the state should introduce relevant policies to support and promote the construction and development of hospital care services for elderly osteoporotic fracture patients.
