The role of National Immunization Technical Advisory Groups (NITAG) in strengthening health system governance: Lessons from three middle-income countries—Argentina,Jordan, and South Africa (2017–2018)

IntroductionToward the Global Vaccine Action Plan 2020 goal, almost 90% of countries have established a National Immunization Technical Advisory Group (NITAG). However, little is known about NITAG's contributions to governance.MethodsIn 2017–2018, a two-step, qualitative retrospective study was conducted. Jordan (JO), Argentina (AR), and South Africa (SA) were selected owing to government-financed NITAGs from middle-income countries (MICs), geographic diversity, and a vaccine introduction with NITAG support. Country case studies were developed, collecting data through desk review and face-to-face key informant interviews (KIIs) from Ministry of Health (MoH) and NITAG. Case studies were analyzed together, to assess governance applying the European Observatory on Health Systems and Policies framework focusing on transparency, accountability, participation, integrity, and policy capacity (TAPIC).ResultsDocument review and 53 KII (22 AR, 20 SA, 11 JO) showed NITAGs played a pivotal role as advisors promoting a culture of evidence-informed policies. NITAGs strengthened governance, although practices varied among countries. Meetings were conducted behind-closed-doors, participation restricted to members, only in one country agendas, and recommendations were public (AR). To increase participation, policy capacity, and transparency, countries considered adding experts in communications, advocacy, and economics. AR and SA contemplated including community members. NITAGs functioned autonomously from the government, with no established internal or external monitoring or supervision. NITAG meeting minutes allowed the review of integrity, adherence to terms of reference, standard operating procedures, and conflict of interest (CoI). For the most part, NITAGs abided by their mandates. Significant issues were related to the level of MoH support and oversight of CoI declaration and documentation.ConclusionsSystematically implementing governance approaches could improve processes, better tailor policies, and implementation. The long-term survival and resilience of NITAGs in these countries showed they play a significant role in strengthening governance. Lessons learned could be useful to those promoting country-driven evidence-informed decision-making.     

中国精神分裂症患者不同家庭干预措施效果比较的meta分析

目的对中国精神分裂症患者采取家庭干预的研究文献进行综合回顾和系统评价, 比较不同条件下家庭干预效果的差异。方法在中国知网、维普、万方、中国生物医学文献数据库四大中文数据库及OVID Medline、Science Direct、Web of Science、EBSCO四大英文数据库中, 检索各数据库建库至2015年1月为止使用社会功能缺陷筛选量表(SDSS)、简明精神病(科)量表(BPRS)、阳性与阴性症状量表(PANSS)研究中国精神分裂症患者家庭干预效果的文献, 以标准化加权均数差( SMD)作为效应量, 采用meta分析比较不同干预时间、不同干预类型、对不同病程和不同严重程度的精神分裂症患者的家庭干预效果差异。 结果共纳入57篇符合标准的文献。SDSS、PANSS分析结果显示:① 干预时间越长干预效果越好( P < 0.0001、 P=0.0025);② 单独家庭干预比多个家庭合并单独家庭干预的效果更明显( P < 0.0001、 P=0.0131);③ 干预对于病情较重患者效果较好( P < 0.0001、 P=0.0280)。SDSS量表还显示家庭干预对于病程短的患者效果更好( P < 0.0001)。 结论家庭干预更适合病程较短的精神分裂症患者, 干预应实施较长时间; 单独家庭干预更有利于患者阴性症状的改善和社会功能的康复, 且对于病情较轻患者的阴性症状改善效果更好。

Therapeutic alliance,relationship building,and communication strategies-for the schizophrenia population: An integrative review

Background

Schizophrenia is a chronic mental illness that affects the client, family, and community. Nurses are educated to use the nurse-patient relationship to provide health education and collaborative health decision-making. However, challenges abound for nurses and clients with schizophrenia to effectively utilize the relationship to reach these goals.

Determinants of Tobacco Use among Children of a Rural Village in India: An Exploratory Qualitative Study

Background: Tobacco is one of the leading causes of preventable deaths. It is both a major social and health problem. According to National Sample Survey Organization of Government of India about 20 million children of ages 10-14 are estimated to be tobacco-addicted. There are grave consequences of tobacco both socially and also on health thus it is of utmost importance to understand the factors leading to its use and to plan strategies to reduce its intake. However, the health implications of this social issue in a rural context have not been explored. Aims and Objective: this study makes an attempt to explore the health and social implications of tobacco usage by the children below the age of 14 years in hamlet. Materials and Methods:  The present study employed a qualitative study design. Data was collected using focus group discussion and in-depth interview of key informants. Thematic analysis for exploring the explicit and implicit meanings within the data was done. The themes which emerged were knowledge about tobacco and the various products available, children and parents’ tobacco use and habits, the health and social implication of tobacco use, reasons for tobacco use by the children. Results: It was found tobacco use by the children was very common in the community. Parent, peer pressure, sibling pressure were found to be playing important role in the initiation of tobacco habit by the child. Further illiteracy and lack of awareness was also lead to tobacco use among children. Conclusion: The study identifies education and awareness of parents about the ill-effects of tobacco play an important role as parents act as role model for their children, thus equal stress should be laid in improving the parental habits. Even raising the prices of tobacco products can help in controlling this habit.     

利培酮和齐拉西酮对精神分裂症患者血浆细胞因子的影响

目的:研究抗精神病药对精神分裂症患者细胞因子的影响。方法:符合ICD-10精神分裂症诊断的60名患者,随机分为利培酮组(给予利培酮治疗)和齐拉西酮组(给于齐拉西酮治疗),并以健康对照组比较,对患者在治疗前及治疗8周后测量血浆IL-2、IL-6及TNF-α水平,并对患者进行PANSS量表评定。结果:两组患者治疗前后血浆IL-2、IL-6及TNF-α水平与对照组比较,差异有统计学意义(P0.05)。两组患者治疗后血浆IL-2、IL-6及TNF-α水平较治疗前降低,差异有统计学意义(P0.05)。治疗前IL-2水平与PANSS量表阳性症状评分呈正相关(r=0.54,P0.05)治疗后TNF-α与阴性症状分呈显著正相关(r=0.41,P0.05)。结论:精神分裂症患者存在免疫功能异常,利培酮和齐拉西酮可以降低精神分裂症患者细胞因子水平。细胞因子水平与精神病理存在一定相关性。
