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 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.

Objective:To analyze the epidemiological characteristics and influencing factors of single-cigarette use and dual cigarette-cigar use in China.Methods:This study was a cross-sectional study that selected 85 638 urban and rural residents who met the inclusion criteria from the 2018 China Health Literacy Survey as research subjects. An analysis was conducted on 21 849 users of cigarettes and cigars among them. Due to the small number of individuals who exclusively used cigars (247 cases), the research subjects were divided into two categories: exclusive cigarette users and dual users of cigarettes and cigars. The groups were categorized by age (18-34 years, 35-54 years, ≥55 years), gender (male, female), education level (primary school and below, junior high school and high school, university and above) and annual household income (<20 000 yuan, 20 000-<80 000 yuan, ≥80 000 yuan) to compare the tobacco usage rate and conduct subgroup analyses for each subgroup. Multivariate logistic regression analysis was employed, incorporating general demographic characteristic information to explore the influencing factors of exclusive cigarette use and dual use of cigarettes and cigars, respectively.Results:The rate of exclusive cigarette use in our country was 24.3%, while the dual use rate of cigarettes and cigars was 0.9%. The exclusive cigarette use rate and the dual use rate of cigarettes and cigars among males were significantly higher than those among females (48.25% vs 2.48%, and 1.84% vs 0.06%) (both P<0.001). For males, the high-risk factors for exclusive cigarette use included living in urban areas ( OR: 1.37, 95% CI: 1.23-1.54), being Han ethnicity ( OR: 1.73, 95% CI: 1.51-1.98), and having an annual household income ≥20 000 yuan ( OR: 1.54, 95% CI: 1.38-1.82) while having a junior high school education or higher was a protective factor ( OR: 0.68, 95% CI: 0.52-0.90). Age≥35 years ( OR: 3.36, 95% CI: 2.62-4.32) and having a junior high school education or higher ( OR: 1.30, 95% CI: 1.02-1.67) were risk factors for dual use of cigarettes and cigars in males. Among females, living in urban areas ( OR: 1.53, 95% CI: 1.19-1.97) and being Han ethnicity ( OR: 5.96, 95% CI: 4.47-7.96) were risk factors for exclusive cigarette use, while having a university education or higher was a protective factor ( OR: 0.28, 95% CI: 0.18-0.42). However, for female dual use of cigarettes and cigars, no significant effects were observed for any demographic characteristics. Conclusions:The use rate of cigarettes alone in China is significantly higher than that of cigarette-cigar dual use, and the rates of cigarette use alone and cigarette-cigar dual use in men are significantly higher than those in women. Tobacco use is being affected by sociodemographic factors, among which place of residence, ethnicity and education level are the main influencing factors of cigarette use alone, and gender, age and education level are the main influencing factors of cigarette-cigar dual use.

Background The residues of pharmaceutical and personal care products (PPCPs) in aquatic environments have become an increasingly prominent urban pollution issue, attracting widespread attention. The analysis of PPCPs pollution in water environments holds profound implications in Zhengzhou, a strategically important city in central China. Objective To analyze the pollution characteristics of PPCPs, such as antidepressants and antibiotics, in rivers of Zhengzhou and assess associated ecological risk. Methods Water samples were collected from three rivers of Zhengzhou, and 13 PPCPs (5 antibiotics and 8 antidepressants) were analyzed quantitatively by high performance liquid chromatography-triple quadrupole mass spectrometry (HPLC-MS/MS) after automatic solid phase extraction. Risk quotient (RQ) was applied to assess ecological risk of PPCPs with high concentration. Results The primary antibiotics pollutants were norfloxacin and ofloxacin, both with a detection rate of 100%. Among antidepressants, venlafaxine and citalopram showed the highest detection rates at 92.3% and 88.5%, respectively. The detected antibiotics with the highest average concentrations included ofloxacin and sulfamethoxazole with concentrations of 99.8 ng·L⁻¹and 96.2 ng·L⁻¹, respectively, while antidepressants venlafaxine and citalopram were detected with the highest average concentrations of 15.2 ng·L⁻¹and 1.35 ng·L⁻¹, respectively. The inter-river comparisons revealed statistically significant differences in contaminant loads (P<0.05). The sums of average PPCP concentrations at sampling points in the Jialu River and Suoxu River were 83.4 ng·L⁻¹ and 100.4 ng·L⁻¹, respectively. The Xiaoqing River exhibited higher pollution levels than both the Jialu and Suoxu Rivers, with a total average concentration of 478.4 ng·L⁻¹, where ofloxacin and sulfamethoxazole were identified as the predominant pollutants. The results of ecological risk assessment indicated the RQ contributed by sulfamethoxazole ranged between 0.50−0.95 in the Xiaoqing River, suggesting a controllable risk but requiring prioritized mitigation strategies. The RQ values of norfloxacin were distributed within the range of 0.10-0.30, indicating a moderate ecological risk. The RQ values for ofloxacin and venlafaxine remained below 0.10, indicating a lower risk level. Conclusion PPCPs contamination is positive in the rivers of Zhengzhou, and sulfamethoxazole and ofloxacin are the primary cantaminants. The Xiaoqing River exhibits the highest pollution levels. The initial risk assessment show that sulfamethoxazole and norfloxacin pose potential ecological risks, requiring prioritized contamination management.
