Oral contraceptive use in relation to age at menopause in the DOM cohort

BACKGROUND: We investigated the hypothesis that long-term use of oral contraceptives (OCs), in particular high-dose OCs, could postpone age at menopause. METHODS: Data was used from 8701 women who participated in a breast cancer screening programme in Utrecht (DOM-3 cohort), and who did not use hormone replacement therapy (HRT) or OCs in the 4 years prior to their last menses. Data on OC-use, menopausal status, age at menopause, year of birth, parity, smoking behaviour, socio-economic status, body mass index and age at menarche was available. Use of high-dose OCs has been defined in this study as OC-use before 1972. The data was analysed by means of linear regression and Cox's proportional hazards analysis. Women still menstruating, women with surgical menopause and women lost to follow-up were censored at their last known date of menstruation. Endpoint was the natural menopause (n = 4589). RESULTS: The use of high-dose OCs advanced the onset of menopause by approximately 1.2 months for every year of OC-use compared with no OC-use. High-dose OC-use for > or = 3 years, adjusted for confounding variables, increased the risk of earlier menopause compared with no OC-use (adjusted hazard ratio 1.12; 95% CI 1.03--1.21). The use of lower dose OCs did not increase the risk of earlier menopause (adjusted hazard ratio 1.00; 95% CI 0.91--1.09). CONCLUSIONS: These results are inconsistent with the hypothesis that long-term use of OCs could postpone the onset of menopause by inhibiting follicle depletion. Possible explanations are discussed.     

甲襞、球结膜微循环的应急观测方法

甲襞、球结膜微循环的应急观测方法是在甲襞、球结膜微循环加权积分综合定量评价方法的基础上，保留权值为４、３的指标，同时观察血管清晰度和红细胞聚集二项指标而形成。同时提供其应急观测积分表、异常分度积分值、诊断标准，并与常规方法进行比较，证明其可以反映绝大部分流态类指标和大部分形态类指标及重要的袢周改变，没有丢失微循环重度异常的信息，保证了重度异常诊断的正确。但在大致正常、轻度异常和中度异常的诊断中应急方法部有判重的倾向，说明应急方法漏掉了一些信息，不能全面地了解微循环的改变，造成了判重的倾向。因此应急方法不能代替常规方法，只能在特定条件下应用。     

Avoiding problems in clinical practice after the pill scare

The publications of 1995 and 1996 on the risk of venous thrombosis associated with the use of the combined oral contraceptive pill (COC) suggested that the risks were lower than previous estimates. The debate, which ensued, ensured that the safety of the COC with regard to arterial and venous disease was reassessed. This review details the importance of contraception for public health. It reassesses critically current prescribing practice in the light of the new publications on Factor V Leiden, arterial and venous disease. Methods of communicating information about the COC are assessed, and the difficulties of transmitting complex scientific data to health care professionals and the general public are debated. The importance of attempting to quantify the benefits and risks of the COC and explaining them in the context of other life events is emphasized.     

急诊腹腔镜治疗出血性宫外孕202例临床分析

目的探讨急诊腹腔镜治疗出血性宫外孕的可能性、优越性。方法回顾分析1998年8月~2005年10月急诊腹腔镜出血性宫外孕402例,随机分为腹腔镜组202例,开腹组200例。比较两组手术时间、并发症、术后病率、术后输卵管通畅情况。结果腹腔镜比开腹手术住院时间短、术后恢复快、并发症少、术后病率少。手术时间,腹腔镜组(1998年8月~2001年12月)比开腹手术组长,(2002年1月~2005年10月)短于开腹组,结论腹腔镜手术应用于急腹症出血性宫外孕,当休克早期,在抗休克的同时行腹腔镜手术较安全、有效,病人术后恢复快、不增加并发症,更适应有生育要求患者。     

医院应急医用物资管理实践与效果分析

医院作为应对突发公共卫生事件的主战场,应急医用物资保障能力至关重要。针对突发公共卫生事件中应急医用物资需求复杂、时间紧迫、专业性强等特点,从应急医用物资的产品目录、需求预判、灵活储备、动态调整和供应商考核评分机制等方面,构建了医院应急医用物资管理流程,提升了医院应对突发公共卫生事件的综合管理能力。     

基于信息化的急诊患者早期分级预警方案效果分析

基于早期预警评分系统,构建了急诊患者早期分级预警方案,并借助信息化手段,将方案嵌入急诊护理信息系统中,设置了颜色分级提醒功能,实现了分级预警闭环管理。实施后,急诊患者生命体征监测频次增加,抢救成功率提高,护理不良事件发生率降低。认为基于信息化的急诊患者早期分级预警方案提高了急救质量,保障了患者安全,但需在医护协作、护理人力分配、信息资源整合等方面持续改进。     

亚定点医院在重大突发公共卫生事件中的实践探索

探索重大突发公共卫生事件中以亚定点医院为代表的医疗管理模式。从上海新国际博览中心W1亚定点医院的实际运行情况出发,对其医疗供需、收治标准、运行效果、存在问题等逐一分析,结合本医疗队的经验,提出新的工作模式和管理思路。亚定点医院为普通型和有基础疾病的新冠病毒阳性感染者提供及时有效的救治,缓解了定点医院的运行压力,但也暴露出人员配置、信息化支撑、院感防控等方面的问题。采取“两级缓冲、双向转诊”的工作模式和“三个快、三个准、三个稳、三个全”的管理方案,可为患者提供及时、有效、适宜的医疗服务,缓解定点医院运行压力。     

Characterizing Emergency Department Use in Assisted Living

ObjectivesLittle is known about emergency department (ED) utilization among the nearly 1 million older adults residing in assisted living (AL) settings. Unlike federally regulated nursing homes, states create and enforce AL regulations with great variability, which may affect the quality of care provided. The objective of this study was to examine state variability in all-cause and injury-related ED use among residents in AL.DesignObservational retrospective cohort study.Setting and ParticipantsWe identified a cohort of 293,336 traditional Medicare beneficiaries residing in larger AL communities (25+ beds).MethodsWith Medicare enrollment and claims data, we identified ED visits and classified those because of injury. We present rates of all-cause and injury-related ED use per 100 person-years in AL, by state, adjusting for age, sex, race, dual-eligibility, and chronic conditions.ResultsRisk-adjusted state rates of all-cause ED visits ranged from 100.9 visits/100 AL person-years [95% confidence interval (CI) 92.8, 109.9] in New Mexico to 162.3 visits/100 AL person-years (95% CI 154.0, 174.7) in Rhode Island. The risk-adjusted rate of injury-related ED visits ranged from 18.7 visits/100 AL person-years (95% CI 17.2, 20.3) in New Mexico to 35.7 visits/100 AL person-years (95% CI 34.7, 36.8) in North Carolina.Conclusions and ImplicationsWe observed significant variability among states in all-cause and injury-related ED use among AL residents. There is an urgent need to better understand why this variability is occurring to prevent avoidable visits to the ED.     

情景模拟演练在儿科急诊新护士带教中的应用效果研究

目的研究在儿科急诊对新护士展开临床带教中,使用情景模拟演练教学法的实际应用效果。方法选择该院于2018年5月—2019年5月期间于该院儿科急诊中入岗新护士共计70名,设为该次实验对象。设立常规组与实验组后,将其平均分成两组并分别纳入作为对应组观察患者。其中常规组(2018年5—12月期间)的35名实习护士沿用传统带教模式展开教学,实验组(2019年1—5月期间)的35名实习护士沿用情景模拟演练模式展开教学。在两组同时期下收集各100例临床患者,在带教周期一月期间为其提供护理工作评价。并对其护士进科前后综合能力考评情况、护理技术考核成绩、护士带教护理满意度、患者满意度评价进行统计。结果进科前,两组对象综合能力考评能力于组间对比差异无统计学意义(P>0.05)。进科后,实验组新护士综合能力考评成绩相比常规组更高,同时实验组护士的儿科护士护理技术考核明显优于常规组,差异有统计学意义(P<0.05)。相比较常规组,实验组新护士对带教满意度明显更高,同时对应组患者对护理工作的满意性更高,差异有统计学意义(P<0.05)。结论给予儿科急诊中入岗新护士情境教学法,对培养其岗前护理技能操作技能效率较高,同时能改变其患者护理满意性,加强新上岗护士综合能力,拉近护患之间关系,是较好的临床带教方法。
