Determinants of overweight and obesity and preventive strategies in Pacific countries: a systematic review

Objective:This study aimed to explore more on contributing factors and prevention of overweight and obesity among Pacific islanders.Methods:Using Cochrane library guideline,four electronic databases,PubMed,Embase,Scopus and CINAHL,were systematically searched from 2010 to 2020.Search strategy included key concepts,free text terms,and database-controlled vocabulary terms to identify articles on determinants and preventative strategies of overweight and obesity in the Pacific countries.A data extraction sheet was developed to extract relevant information required for analysis and theme development for this study.Results:A total of 22 articles were summarized and categorized.Determinants of overweight and obesity identified two themes:environmental related factors 13.6%(3/22)and sociocultural related factors 27.3%(6/22).The preventative strategies of overweight and obesity was categorized into behavioural change 22.7%(5/22),school-related 18.2%(4/22),and policies 50%(11/22).The quality assessment of articles showed“Good”68.2%(15/22),and“Fair”31.8%(7/22).Conclusion:This study highlighted two contributing,non-medication factors affecting overweight and obesity are both environmental and socio-cultural issues.Overweight and obesity preventative strategies identified in the Pacific context considered behavioural change,knowledge enhancement,and policy development.Further research should aim at exploring the current preventative strategies in-depth,to appreciate the most feasible and recommended preventative approach within the Pacific society.

Use of Social Cognitive Theory to Assess Salient Clinical Research in Chronic Disease Self-Management for Older Adults: An Integrative Review

The purpose of this integrative review is to evaluate research pertaining to self-management programs for older adults with chronic diseases using Albert Bandura’s Social Cognitive Theory (SCT) for behavior change. The focus is application of the SCT domains to self-management programs. The exploration of the current chronic disease self-management research provides an understanding of the Social Cognitive Theory concepts studied in interventional self-management research. The integrative review explicated two areas related to the theory in need of further research. First, social support has not been thoroughly explored as a mechanism for enhancing self-management interventions. Second, moral disengagement was not identified as a focus within chronic disease research raising the question about the impact of moral disengagement on long-term adherence and behavior change.

“前车之鉴”对教育数字化的启迪

出于对追赶世界一流的渴盼,近代中国长期不懈地关注器物文明。对这种历史实践的反思有助于教育数字化的健康发展。其一,明确教育数字化的指导理念,体用统一而中和,融洽共生而相互作用。教育数字化不应只关注表层的“用”,更应关注内核的“体”,即教育技术文化的进步,由此才能触发深层次的教育变革;其二,应走出技术决定论和物本发展观的误区,认识到物只是发展条件,技术本无力承担变革教育的重任,人的开悟才是影响教育发展的核心因素;其三,教育数字化应树立物与人辩证统一的协调发展观,主要包括发展的主要矛盾与次要矛盾的统一、发展平衡与不平衡的统一以及发展短板与潜力的统一。借助上述的历史启迪,人们能够更为警醒地认识当前教育数字化面临的问题,以便有效地探索其发展道路。

自动化阴道分泌物分析系统复检规则的建立与验证专家共识

阴道分泌物显微镜检查(镜检)是妇产科检查的常规项目,随着检验技术自动化的发展,基于不同检测原理的自动化阴道分泌物分析仪器被开发应用,以满足临床大样本量、高效、标准化的需求。目前,湿片/革兰染色镜检仍然是诊断女性常见生殖道感染性疾病的金标准,是自动化仪器检测结果准确性评估的参考方法。当前的质量文件尚缺乏对体液范畴内阴道分泌物自动化检测复检规则的统一要求和细则指导,中国老年保健医学研究会检验医学分会和上海市优生优育科学协会(上海市妇幼保健协会)检验医学专委会基于中国国家标准、行业标准、质量体系要求和国内外相关指南、文献,在自动化阴道分泌物分析系统复检规则的建立、验证、规则应用等方面形成共识,共同制定《自动化阴道分泌物分析系统复检规则的建立与验证专家共识》,以期能更好地规范自动化阴道分泌物分析系统复检规则的建立,保证检验结果的准确性。

被污名化群体创伤后成长的社会心理决定因素及社会工作干预路径

对被污名化群体的创伤后成长研究尚停留在独立影响因素层面,未形成系统化的理论模型或框架结构,使健康社会工作相关循证干预受阻。文章运用范围综述方法,借鉴健康的社会决定因素理论,在知网和Web of Science等高质量论文数据库中检索到了符合标准的114篇文献。整合相关结果发现,被污名化群体的创伤后成长存在五类影响因素:社会文化背景、家庭及邻里社区环境、资源获取条件、创伤事件性质、人格特质与认知进程。初步建构的“被污名化群体创伤后成长的社会心理决定因素框架”能够为健康社会工作领域开展相应理论研究与实务工作提供依据。

肠道菌群及其代谢产物氧化三甲胺与冠心病相关性的中西医研究进展

冠状动脉粥样硬化性心脏病,临床上也称为冠心病,是一种发生率较高的心血管疾病类型,且年轻化趋势明显。从以往的临床实践结果来看,冠心病的常见影响因素包括吸烟、高血压病、糖尿病、高脂血症等。肠道菌群代谢产物氧化三甲胺(TMAO)也是近年来研究证实的一种冠心病影响因素。TMAO可以提升人体的巨噬细胞清道夫受体水平,进而增强血浆胆固醇以及炎症细胞因子的表达,这也是导致细胞热休克蛋白含量升高的原因,直接增加人体的冠心病发生风险,并持续诱发疾病的恶化。针对这一情况,医学领域更加倾向于结合TMAO检查结果开展冠心病的预防和治疗。不同的肠道菌群结构,对三甲胺(TMA)与相应的转化途径加以调节,有利于TMAO水平的抑制,最终起到抑制冠心病的作用。笔者从中医和西医2个维度,对肠道菌群及其代谢产物TMAO与冠心病的关系及相关技术方法的研究进展进行了论述分析。

夫妻共同债务认定规则:内涵检审与司法适用

《民法典》第1064条规定的夫妻共同债务认定规则,规范表达简练、种类概括简易。为确保夫妻共同债务认定规则的适用吻合立法本意,应对其规范内涵、适用规则进行检视。认定合意型夫妻共同债务,应以保护配偶方的“同意权”为原则,若将其“知情”推定为“夫妻合意”,并以此推定该债务为夫妻共同债务,既有违意思自治原则,也欠缺逻辑推理的严谨性,导致债务性质认定欠缺正当性。认定生活型夫妻共同债务,应注重分析家庭日常生活需要的适当性,并要求债权人承担所借债务已用于夫妻共同生活的证明义务。认定生产经营型夫妻共同债务,应同时关注夫妻共同参与生产经营以及夫妻一方经营、另一方共享经营收益的情形,原因在于其均具有夫妻共同生产经营的意志。谨慎适用夫妻共同债务认定规则,有助于维护民众的合法权益,促进社会的和谐稳定。

论刑事诉讼中事故调查报告的证据能力

2021年修订的《刑诉法解释》第一百零一条对事故调查报告的证据能力进行了规定。对事故调查报告在刑事诉讼中的证据能力直接进行规范,为其在实践中作为证据使用提供了法律依据,化解了事故调查报告无法适用现行行刑证据转化规定进入刑事诉讼程序的问题。因对事故调查报告证据能力的规定不具体,存在事故调查报告无法归入法定证据种类、事故调查报告各部分是否均具有证据能力、事故调查报告证据能力审查规则模糊等争议问题。为了规范事故调查报告在刑事诉讼中的适用,需要进一步讨论在我国立法框架下,如何突破法定证据种类的限制、明确事故调查报告各部分的证据能力、从相关性、合法性和可靠性等方面完善审查规则。
