女性致密性骨炎血清骨转换生化标志物水平变化研究

背景 致密性骨炎（OCI）和其他疾病有时难以鉴别，探讨血清骨转换生化标志物可为OCI的鉴别诊断提供依据。 目的 探索女性OCI患者的血清骨转换生化标志物的水平变化及临床意义。 方法 回顾性选取2013年6月至2022年2月在北京积水潭医院门诊及住院诊断为OCI的61例女性患者作为观察组，年龄15~50岁，平均（33.8±6.6）岁，病程2周~15年。选择同期61例女性体检健康者作为对照组，年龄15~48岁，平均（35.6±7.6）岁。比较两组一般临床资料和血清骨转换生化标志物水平，并对血清骨转换生化标志物与病情相关指标进行相关性分析。 结果 观察组血清白蛋白（45.4±2.9）g/L低于对照组（46.5±2.8）g/L（t=2.190，P<0.05）。血清骨转换生化标志物比较结果显示，观察组血清1型胶原羧基末端肽β特殊序列（β-CTX）〔0.28（0.23，0.37）μg/L〕、N-端骨钙素（OC）〔13.1（11.2，16.2）μg/L〕、25-羟维生素D3〔25-（OH）VD3〕〔（14.1±5.1）μg/L〕低于对照组〔0.36（0.29，0.48）μg/L，15.6（13.7，17.3）μg/L，（17.5±6.6）μg/L〕（Z=-2.983、-3.255，t=3.081，P<0.05）。长病程亚组OC水平〔14.6（12.4，18.5）μg/L〕高于短病程亚组〔11.7（10.2，14.0）μg/L〕（Z=-2.407，P<0.05）。多孕亚组β-CTX〔0.25（0.22，0.32）μg/L〕、OC水平〔12.2（10.3，15.0）μg/L〕低于非多孕亚组〔0.33（0.26，0.44）μg/L、13.4（12.0，18.8）μg/L〕（Z=-2.486、-1.897，P<0.05）。相关性分析显示，观察组血清1型前胶原氨基端延长肽（tP1NP）与妊娠次数、生产次数均呈负相关（rs=-0.276、-0.298，P<0.05），OC与体质指数（BMI）、视觉模拟评分法（VAS）评分、妊娠次数均呈负相关（rs=-0.284、-0.374、-0.360，P<0.05），25-（OH）VD3水平与BMI呈正相关（rs=0.275，P<0.05）。 结论 女性OCI患者血清OC、β-CTX水平明显降低，可为鉴别其他疾病提供依据；血清OC水平可以反映OCI患者的严重程度，同时OC水平与患者妊娠次数相关；tP1NP与妊娠次数、生产次数相关。     

贵州省"5+3"模式订单定向医学毕业生的离职意愿及影响因素研究

背景 我国基层全科医生的离职意愿较高，调查其离职意愿并分析影响因素，可以为减少基层卫生人才流失提供思路。目前，完成"5+3"模式（5年临床医学本科教育+3年住院医师规范化培训）培养的订单定向医学毕业生逐步履约进入基层工作，而针对该部分全科医生离职意向的研究相对较少。 目的 调查贵州省"5+3"模式订单定向医学毕业生回归基层工作后的离职意愿及影响因素，为完善吸引卫生人才留任、建设基层全科医生队伍相关政策提供依据。 方法 以贵州省截至2020年底已完成"5+3"模式培养并履约到基层医疗卫生机构工作的2015—2017级订单定向医学毕业生为研究对象。于2021-01-20至2021-02-10对其开展电子问卷调查，内容包括毕业生的一般情况、职业满意度、离职意愿、服务期满后职业方向。共回收问卷347份，其中有效问卷311份，问卷有效回收率为89.6%。采用单因素分析及多元逐步线性回归分析全科医生离职意愿的影响因素。 结果 贵州省"5+3"订单定向医学毕业生的整体离职意愿得分为（3.98±0.98）分，具有离职倾向者229例（73.6%）。不同性别、单位地理位置、每日工作量者的离职意愿得分比较，差异有统计学意义（P<0.05）。多元逐步线性回归分析显示，单位负责人对待下属的方式、在工作中获得的成就感、对当前收入满意程度、家人对工作的支持程度、当地激励政策执行程度是"5+3"订单定向医学毕业生离职意愿的影响因素（P<0.05）。服务期满后，计划留任原基层医疗卫生机构者12例（3.9%），计划去其他基层医疗卫生机构者21例（6.7%），计划离开基层去上级医院工作者196例（63.0%），计划攻读全日制硕士学位者60例（19.3%）。 结论 贵州省"5+3"模式订单定向医学毕业生的离职意愿较高，预计服务期满后基层全科人才流失较多，需从提高收入、重视全科医生心理需求、优化全科医生培养与使用、发展基层医疗卫生机构、加强全科宣传等方面着手改善。     

男性类风湿关节炎患者骨量减低的相关研究

目的探讨男性类风湿关节炎(rheumatoid arthriti,RA)患者骨量减低的相关情况及合并骨质疏松的危险因素。方法收集2013年8月至2019年5月在苏州大学附属常州市肿瘤医院诊治的男性类风湿关节炎患者38例,年龄(64. 39±9. 44)岁,对照组为40例健康正常人群,年龄(63. 53±8. 14)岁。通过双光能X线骨密度仪测定正位腰椎(L1～4)及左侧股骨近端(包括FN、Troch、Ward、Total)骨密度;运用电化学发光免疫分析法检测BAP、BGP、CTX;记录RA患者的ESR、CRP、关节肿胀及压痛数、RF以及CCP等情况。分析比较两组骨密度及骨生化指标的差异,并采用单因素分析和多因素Logistic回归分析调查类风湿关节炎患者合并骨质疏松的危险因素。结果两组间年龄、体质量指数(body mass index,BMI)差异无统计学意义(P0. 05)。类风湿关节炎组左侧股骨颈、整体髋骨BMD测量值较对照组减低(P0. 05);且类风湿关节炎组骨量减少、骨质疏松发生率较对照组显著增高(P0. 05);在骨生化指标方面,类风湿关节炎组CTX水平高于对照组(P0. 05)。单因素分析显示BMI、CRP、DAS28-ESR及CTX与男性类风湿关节炎患者继发骨质疏松相关(P0. 05);多因素Logistic回归分析显示,BMI 18. 5 kg/m2(OR=0. 014),DAS28-ESR5. 1(OR=21. 433)及CTX0. 7 ng/m L(OR=25. 875)是男性类风湿关节炎继发骨质疏松的独立危险因素(P0. 05)。结论男性类风湿关节炎患者同样易合并骨质疏松的发生,BMI、DAS28及CTX等危险因素应高度重视。     

Turnover Rates and Factors Influencing Turnover of Korean Acute Care Hospital Nurses: A Retrospective Study Based on Survival Analysis

PurposeThis study aimed to explore turnover rates for Korean acute care hospital nurses and identify factors influencing their turnover.MethodsThe study was retrospective in nature. Nurse cohort data were obtained from hospital status data from Korea's Health Insurance Review Assessment Service. The observation period was from January 1, 2012 to December 31, 2016, and data for 96,158 nurses were analyzed. Independent variables included nurses' age and sex and hospital setting, type, ownership, and nurse staffing level. Kaplan–Meier analysis was performed to estimate survival curves, and factors influencing turnover were analyzed using Cox's proportional hazard regression.ResultsThe cumulative turnover probability for all nurses was .17, .29, .38, .45, and .50 for the first, second, third, fourth, and fifth years, respectively. The results showed that the longer the career duration, the lower the turnover rates. According to the factors influencing nurse turnover, both nurses' (i.e., sex and career duration) and hospitals' (i.e., hospital setting, type, ownership, and nurse staffing level) characteristics were statistically significant.ConclusionIt should be noted that the turnover rate of nurses with less than three year of career duration and of those with less than one year has been shown to be quite high. Therefore, target populations for acute care hospital nurse turnover should be expanded from new graduate nurses to experienced nurses with less than 3 years of career. Further studies are required to examine the causes of high turnover rates in hospitals that are small and/or have low nurse staffing levels.     

Factors Affecting the Intention to Quit among Women Smokers in Turkey

Objectives: Tobacco use is an important public health problem that affects adversely the quality of life. A person’s attitude toward quitting tobacco use can be reflected by the desire or intention to quit smoking. The aim of this study was to determine risk factors affecting women’s intention to quit tobacco in Turkey. Methods: In this study, the data obtained from the Global Adult Tobacco Survey (GATS) were used. The GATS is a standard method used in countries to monitor and evaluate the frequency of tobacco use in adults and tobacco control practices. The data used in the study was obtained from the GATS carried out in Turkey in 2008 and 2012. The data related to 1248 women smoking tobacco were used in the analysis. The relationship between women’s intention to quit tobacco use and socio-demographic and economic variables was examined. Results: Men were excluded from the analysis because the focus of the study was women. It was determined that 732 of 1248 women using tobacco intend to quit smoking tobacco. 40.4% of women smoking tobacco are primary school graduates. Women, who were aware of anti-smoking messages and exposed to stimulants that promote smoking, were 36.4% and 27% more likely to intend to stop tobacco use after the next month, respectively. It was observed that women living in a house, where smoking is allowed, are less likely to quit smoking than others (ME = -0.522). This shows the importance of domestic restrictions. Conclusion: Intending to quit is an important preliminary step to quit. Understanding the factors associated with the intention to quit smoking can help tobacco users to stop using it and shape effective policies to increase the quit rates.
