阈值校正方式对PET脑显像统计参数图分析显示结果的影响

目的 探讨各种阈值校正方法对统计参数图(SPM)软件统计比较结果显示的影响.方法 利用Hoffman标准脑模型制作缺损模型PET成像与正常模型PET成像,进行统计参数图的统计比较.并选取脑梗死患者与健康检查者进行统计参数图的统计比较.结果 校正与非校正产生的结果有差异,其中族错误率(FWE)校正(P=5×10-2)得到的统计分析结果激活区最少及最小,其次是错误发现率(FDR)校正(P=5×10-2),非校正方式(P=1×10-3)得到的激活区最多及最大.但FDR校正效果不稳定,有时不如不校正.结论 统计参数图软件中FWE校正方法可明显降低假阳性,得到的结果可信度稳定地高于非校正方法.     

Phenomenology and family history in DSM-III psychotic depression

Depressed inpatients with psychotic features were compared to those without them in terms of demographic features, depressive symptoms at intake and family history. These variables were then used to compare patients with mood-congruent psychotic features to those with mood-incongruent psychotic features. Patterns of familial psychopathology were similar for psychotic and non-psychotic patients. In accord with other studies, the families of mood-incongruent patients had slightly more schizophrenia and significantly less depression than did the families of mood-congruent patients. Depressive symptoms, particularly those used to define major depression and melancholia, were more severe in psychotic patients. Moreover, these particular depressive symptoms were more likely to distinguish mood-congruent from mood-incongruent patients than were other depressive symptoms. Thus mood-congruent psychotic features accompanied a more typical depressive syndrome than did mood-incongruent psychotic features.     

Neuroendocrine and Cardiovascular Stress Reactivity in Middle-Aged Normotensive Adults with Parental History of Cardiovascular Disease

Neuroendocrine and cardiovascular stress reactivity was studied in healthy middle-aged individuals whose parental history included essential hypertension and/or myocardial infarction and a control group without parental history of cardiovascular disease. All subjects completed a rest session (1 hour) and a stress session (1 hour). The stress session included behavioral (mirror image tracing, mental arithmetic, and the Stroop color word conflict test) and physical stressors (the cold pressor test and isometric exercise). Systolic and diastolic blood pressures and heart rate were recorded at baseline before and during all stressors. Specimens for determination of urinary catecholamines and cortisol were sampled after the rest and stress sessions respectively. Generally, a parental history of hypertension but not of myocardial infarction influenced neuroendocrine and cardiovascular stress reactivity. A family history of hypertension was associated with exaggerated epinephrine, norepinephrine, and cortisol excretion during stress and with enhanced heart-rate reactivity to behavioral (mental arithmetic and mirror image tracing) but not to physical stressors (isometric exercise or the cold pressor test). We conclude that individuals with a family history of hypertension tend to display exaggerated cardiovascular and neuroendocrine reactivity to stress.     

成都市家庭医生服务现状的定性研究

目的 本研究针对成都市基层医疗卫生服务机构,调查分析了家庭医生服务开展现况、存在的问题,以及家医服务平台的建设情况并提出了改进建议。方法 本研究共抽取了成都市六个基层社区卫生服务机构,对每家机构的1名管理人员和1个家庭医生团队分别进行深入访谈和专题小组访谈,调查时间为2020年12月—2021年2月。结果 成都市双向转诊取得一定成效,但下转难情况依然突出;有偿签约效果不好,居民就诊观念需转变;基层卫生技术人员不足,家医服务增加了日常工作量;家医信息化平台存在诸多问题,功能亟需改善;家医的绩效考核制度有一定激励作用,但仍需完善;基层卫生投入不足,家医政策落地难。结论 规范分级诊疗秩序,畅通双向转诊通道;加强官方媒体宣传力度,转变居民就诊观念;提升基层职业吸引力,培养优质人才;加强信息化建设,完善家庭医生信息化服务平台;健全家庭医生绩效考核制度,调动工作积极性;完善家医配套政策与措施,强化基层机构服务能力。     

我国家庭医生服务签约意愿相关因素的Meta分析

目的探讨我国家庭医生服务签约意愿的相关因素,为家庭医生服务实践提供参考。方法检索PubMed、Embase、Cochrane Library、中国知网数据库（CNKI）、万方数据库、维普期刊数据库中公开收录的关于我国家庭医生服务签约意愿的横断面研究,提取相关数据后运用Stata 15软件进行Meta分析。结果最终纳入21篇文献,累计调查人数23 727人,签约家庭医生服务12 328人,签约率为51.96%。Meta分析显示,年龄≥60岁、有医疗保险、有婚姻史、有慢病、知晓家庭医生签约服务、接受社区首诊是家庭医生服务签约意愿的促进因素,民族为汉族、自评健康状况好或者一般是家庭医生服务签约意愿的阻碍因素。结论我国家庭医生服务签约仍有进一步发展空间,对于汉族、自评健康状况好或者一般的人群需要采取更多的鼓励措施。     

Adverse Childhood Experiences and Suicidal Behaviors Among Youth: The Buffering Influence of Family Communication and School Connectedness

PurposeThe main objectives of this study were to determine (1) whether family communication and school connectedness offer protection against suicidal behaviors in the presence of adverse childhood experiences (ACEs; direct protective effect) and (2) whether family communication or school connectedness buffer the association between ACEs and suicidal behaviors (interacting protective effect) on the multiplicative and additive scales.MethodsData were obtained from a western state's 2019 Youth Risk Behavior Survey that included 5,341 middle school and 4,980 high school participants. Generalized linear models were used to estimate whether family communication and school connectedness offered direct protection against suicidal behaviors or buffered the association between ACEs and suicidal behaviors using adjusted prevalence ratios and corresponding 95% confidence intervals.ResultsFamily communication and school connectedness offered direct protection against suicidal behaviors in the presence of ACEs (a 1-unit higher score was associated with a 32%–42% lower prevalence of suicidal behaviors for middle school youth and a 27%–39% lower prevalence of suicidal behaviors for high school youth). There was evidence that family communication and school connectedness buffered the association between ACEs and suicidal behaviors on the multiplicative scale.ConclusionsThe findings provide support for the development and implementation of interventions that build family communication and school connectedness to reduce suicidal behaviors. Furthermore, screening for trauma and suicidal behaviors is warranted.     

Short sleep duration at night in 2.5-year-old children is associated with childhood obesity at age 5.5 years: The Japanese children cohort study

BackgroundObesity in children contributes to higher risks of various chronic diseases in adulthood and the prevalence has increased worldwide including Japan.ObjectivesThis study aims to examine the association between sleep duration at night in children aged 2.5 years and the subsequent risk of obesity at age 5.5 years.MethodsThis study is embedded in the Longitudinal Survey on Babies Born in the 21st Century, which recruited families who had a child born in Japan in 2001. The multivariable logistic regression models were applied to calculate odds ratios (OR) and 95 % confidence intervals (CI) of childhood obesity at 5.5 years, defined as percentage of overweight (POW) ≥ 20 % and body mass index (BMI) ≥ 95th percentile of this study population according to sleep duration at night collected at 2.5 years child age.ResultsAmong 25,378 children, 2.6 % and 3.7 % were obese at age 5.5 years defined by POW and BMI respectively. Compared with night sleep duration > 11 h/d, shorter sleep durations in 2.5 years-old children were associated with higher risk of obesity at 5.5 years; the multivariable ORs (95 %CI) were 1.05 (0.81–1.35), 1.23 (0.93–1.62) and 1.54 (1.04–2.31) for sleep duration 10, 9 and ≤ 8 h/d, respectively; p-trend = 0.03. The observed association differed according to the children (child’s sex, napping habits, and children frequently play at park), and family characteristics (mother’s age at delivery and mother’s level of education).ConclusionShort night sleep duration among girls aged 2.5 years was associated with risk of obesity at age 5.5 years, suggesting the importance of sufficient sleep duration at night for the prevention of obesity.     

儿童心理问题的家庭治疗原则与策略

儿童心理问题的常规治疗包括心理治疗和药物治疗,但是两者具有一定的局限性和社会不适性。家庭对儿童的成长具有重大影响,也是儿童出现心理问题的重要源头,所以家庭的介入对于心理问题儿童的治疗非常关键。家庭治疗的主要原则包括培养儿童的独立性、解决儿童与外界之间的冲突以及重视家庭成员间的和谐关系。家庭治疗所采取的策略主要是转变家庭内部态度、重视家庭的整体性、心理治疗和家庭治疗的互相配合以及对医学诊断的重视。在专业医学诊断指导下,通过家庭介入传统的心理治疗,从而更好地改善儿童所面临的心理问题。本文回顾了现有的儿童心理问题的研究成果,强调了家庭对儿童心理问题的影响,总结了儿童心理问题的家庭治疗原则和策略。     

影响10—12岁学龄儿童行为的家庭因素分析

目的 探讨学龄儿童行为问题及影响因素。方法 采用Rutter儿童行为问卷（父母问卷）评价儿童行为,采用Moss家庭环境量表（FES）和自拟的儿童行为问题影响因素调查,调查10－12岁城市学龄儿童325名。结果 学龄儿童行为问题检出率为9．7％;儿童行为与家庭成员的情感表达程度、家庭人员间亲密度呈显著负相关（P＜0．05）;经多因素分析,儿童行为问题的影响因素主要有家庭成员情感表达、家庭道德观。结论 儿童行为与家庭环境有密切关系,和谐的家庭气氛、良好的家庭道德观念是促进儿童行为发育的有利条件。     

流动人口的计划生育管理分析

对1998年在上海闵行区开展的“以现居住地为主”的计划生育综合干预项目中外来育龄妇女的计划生育管理状况进行分析,综合运用定量与定性研究方法以了解她们的计划生育管理状况及对计生管理的态度和要求,评价计生管理干预对改善本市外来育龄妇女的计生管理状况及提高她们对计划生育管理的认知的效果。结果显示：通过管理干预,外来育龄妇女携带原籍计划生育证明的比例和持有计划生育信息卡的比例以及暂住证上加盖计划生育合格章的比例均明显增加,妇女对计划生育服务的满意度也明显增加。认为“以现居住地为主”的流动人口计划生育管理有助于计划生育管理,应进一步加强流入地与流出地的联络、协调与积极配合,加强流动人口的计生双向管理。
