妊娠期体育锻炼干预对自然分娩影响的Meta分析

背景 自然分娩是人类繁衍的正常生理过程，中国剖宫产率超出了世界卫生组织（WHO）提出的警戒线2倍多，而体育锻炼作为一种非药物性的健康干预方式，应引起相关部门的重视。 目的 运用Meta分析方法检验妊娠期体育锻炼对自然分娩影响的干预效果，并提出最优的锻炼方案。 方法 检索中国知网（CNKI）、中国生物医学文献服务系统（CBM）、维普网中文数据库和PubMed、EMBase、Web of Science、Cochrane Library英文数据库中有关妊娠期体育锻炼干预影响自然分娩结果的随机对照试验（其中干预组以体育锻炼干预为唯一干预方式，对照组进行常规护理知识教育或不进行有规律的体育锻炼），同时追踪相关系统评价所引用的参考文献，检索时间为1990—2021年。提取纳入文献资料，并对纳入文献进行方法学质量评价，采用RevMan 5.2软件进行Meta分析，运用GRADE工具对结局指标进行质量评价。 结果 共纳入30篇文献。Meta分析结果显示，干预组自然分娩发生率高于对照组〔RR=1.34，95%CI（1.28，1.40），P<0.000 01〕。亚组分析结果显示，锻炼开始节点对自然分娩的干预效果从高到低依次为：>24周、13~24周、≤12周；锻炼内容对自然分娩的干预效果从高到低依次为：盆底肌训练、运动课、体操、有氧运动、分娩球、瑜伽；锻炼频率对自然分娩的干预效果从高到低依次为：≥12次/周、3~5次/周、6~8次/周、9~11次/周；中等强度的锻炼较低强度的锻炼对自然分娩具有更大的影响；锻炼时长对自然分娩的干预效果从高到低依次为：30~<50 min/次、<30 min/次、≥50 min/次；锻炼周期对自然分娩的干预效果从高到低依次为：≤8周、17~24周、9~16周、25~34周。绘制体育锻炼干预对孕妇自然分娩影响的漏斗图，结果显示，漏斗图左右两侧基本对称，发表偏倚较小。运用GRADE工具对结局指标进行质量评价，结果显示，妊娠期体育锻炼影响自然分娩的评级为中等级。 结论 孕妇在妊娠期进行一定的体育锻炼对自然分娩结果具有良好的干预效果，且从妊娠期>24周开始锻炼、≥12次/周、30~<50 min/次、持续进行≤8周的中等强度的盆底肌训练、运动课、体操、有氧运动、分娩球以及瑜伽均对孕妇自然分娩的选择具有积极的影响。     

La pleine conscience incarnée : un concept unificateur entre les traditions orientales et occidentales de la pleine conscience

ObjectiveThe interest in mindfulness as a concept continues to grow as shown in the increase in the number of publications pertaining to mindfulness in the last four decades. This increase is also a reflection of the fact that the term “mindfulness” is currently used as an umbrella for a variety of approaches that assign different meanings to the same word. Although differences among varying conceptualizations and definitions of “mindfulness” have been previously highlighted, few efforts have attempted to compare these varying conceptual approaches as a means to address commonalties between them. Therefore, the objective of this paper is to review different conceptualizations of mindfulness in order to understand their common and distinctive components.MethodIn order to investigate commonalities and distinctions among different mindfulness conceptualizations, we conducted a thorough qualitative review of theoretical and empirical papers belonging to three approaches in mindfulness: Eastern Buddhist traditions, Western modern mindfulness meditation programs, and Langerian mindfulness. Each of these approaches is presented first at a conceptual level (i.e., how it defines mindfulness) and then at a practical level (i.e., how to operationalize mindfulness). Empirical research pertaining to the effectiveness of each approach is presented and discussed. As Buddhism incorporates different schools of thoughts, this paper focuses primarily on the conceptualization of mindfulness outlined within Theravada Buddhism. It operationalizes mindfulness through an engagement in intensive and daily meditative practice, which includes both concentrative and open-monitoring meditation. In addition, Buddhism includes a set of ethical principles. Western modern mindfulness meditation programs are conceptualized according to Kabat-Zinn and other western scholars. Definitions varied to some extent according to different scholars, each including a different set of components (e.g., attention, awareness, acceptance, nonjudgement, observation). Western modern mindfulness meditation programs are operationalized though the development and implementation of structured psychosomatic interventions, such as Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy. Langerian mindfulness is conceptualized as a general style or mode of functioning through which individuals actively reconstruct their environment by creating new categories or distinctions, and seeking multiple perspectives. Langer operationalized mindfulness through a set of sociocognitive tasks. The role of the body in these three approaches and more specifically the mind-body connection is highlighted through the analysis of clinical, behavioral, and neuroscientific research findings.Results and DiscussionDefinitions from both eastern and western approaches share self-regulation of attention and awareness as central common elements. Both attention and awareness processes increase interoceptive and exteroceptive body awareness and mind-body connection, therefore suggesting a role of embodiment in conceptualizing and operationalizing mindfulness across different approaches. We therefore introduce the new concept of Embodied Mindfulness as an integration of top-down and bottom-up processes and argue for its utility in the empirical study of mindfulness across the three conceptual approaches.ConclusionsThe new notion of embodied mindfulness integrates different conceptualizations of mindfulness by allowing a common understanding of the mechanisms of change across these conceptualizations. This new notion has also both research and clinical implications. This new notion suggests further emphasizing the body and mind-body connection in both studying/measuring mindfulness and in developing/validating clinical interventions.     

正念减压疗法对妊娠呕吐妇女负性情绪和生活质量的影响

目的 探析正念减压疗法对妊娠呕吐妇女负性情绪和生活质量的影响。 方法 将2017年5月-2018年5月在我院治疗的90例妊娠呕吐妇女纳入本研究,采用数字表法随机分成研究组和对照组,每组各45例。对照组接受宣教,研究组在对照组上实施正念减压疗法。分别于入组时、干预4周和干预8周采用焦虑自评量表(self-rating anxiety scale,SAS)、抑郁自评量表(self-rating depression scale,SDS)、生活质量综合评定问卷(generic quality of life inventory-74,GQOLI-74)进行评估,比较2组妊娠呕吐妇女负性情绪和生活质量。 结果 2组SAS、SDS评分及生活质量综合评定问卷总分在组间效应、时间效应及交互效应上差异具统计学意义。 结论 妊娠呕吐妇女进行正念减压疗法,能够显著减轻妊娠呕吐妇女负性情绪和提高生活质量,值得在临床上广泛应用。     

舒适护理在妊娠合并症患者中的效果评价
