Immunity debt or vaccination crisis? A multi-method evidence on vaccine acceptance and media framing for emerging COVID-19 variants

Renewed COVID-19 outbreaks, stemming from the highly infectious Delta and Omicron variants, prompted rising fears of a ‘pandemic among the unvaccinated’. To address this prevalent vaccination crisis, media framing communication strategies can amplify the scientific evidence on COVID-19 vaccines to reach diverse geographic and socio-economic communities. The critical role of media framing strategies to engage and encourage large populations regarding vaccine acceptance has been rarely studied, despite growing evidence on vaccine hesitancy. The present study used a multi-method approach (i.e., content analysis and quasi-experiments) that unpacked the framing practices employed by the mainstream media in Pakistan. The findings of the content analysis revealed that the media extensively used uncertainty, conflict, consequences, and action rather than new evidence and reassurance frames in its COVID-19 related campaigns. In a series of quasi-experiments involving 720 participants, we manipulated these six frames of COVID-19 related news coverage (i.e., uncertainty, conflict, consequences, action, new evidence, and reassurance) to investigate the underlying mechanism that influences vaccine acceptance. The findings established that the message-consistent effects of media frames manifesting fear (e.g., consequence and uncertainty) and action cues made receivers more supportive of vaccination. The present study findings theoretically address the calls for a more inclusive “community-health reporting model”, besides offering new evidence on the media framing strategies to deliver more targeted, meaningful, and effective campaigns to raise public acceptance for COVID-19 vaccines.     

Swedish neonatal nurses’ experiences of enhancing attachment to children born prematurely

The purpose of this study was to illuminate pediatric neonatal nurses' (PNNs') experiences of enhancing early attachment for the premature children in neonatal intensive care (NIC). An interview study with 8 PNNs in NIC in southeastern Sweden was conducted, and analyzed by content analysis. Result, illustrated three categories: Enabling closeness between the child and the parents, Supporting parents’ sense of parenthood, and Obstacles to enhancing attachment. Discussion, PNNs have a great role to supporting parents, but several barriers need to be addressed to make it easier for the PNN in NIC to enhance attachment for the child.

基于网络药理学的气滞胃痛颗粒抗炎镇痛活性作用分析

目的通过网络药理学的方法预测气滞胃痛颗粒抗炎镇痛主要活性成分的作用靶点,结合中医方解配伍理论对其多成分-多靶点-多通路的作用进行分析。方法基于TCMSP中药系统生物学分析数据库收集气滞胃痛颗粒中6味中药的主要化学成分,并借助LC-MS技术对所筛成分进行分析,通过TCMSP检索和Pharmmapper软件预测获取各成分主要的作用靶标,并通过DIP数据库,利用蛋白质相互作用信息建立药物靶标与炎症疼痛靶标的关联,构建药物-靶标-疾病网络,通过网络特征分析气滞胃痛颗粒抗炎镇痛的作用靶标,阐释其抗炎镇痛的主要作用机制。结果根据网络分析,共有44个炎症疼痛靶点与气滞胃痛颗粒密切相关,其中直接作用靶点有20个,主要是对环加氧酶-2(COX-2)和诱导型一氧化氮合酶(i NOS)等蛋白酶的作用,作用机制可能与调节肿瘤坏死因子(TNF)信号通路、NOD样受体(NLR)信号通路、血管内皮生长因子(VEGF)信号通路等与炎症疼痛密切相关的信号通路有关。结论气滞胃痛颗粒抗炎镇痛作用体现了中药多成分、多靶点、多途径的作用特点,该研究为深入阐释气滞胃痛颗粒抗炎镇痛作用机制提供科学依据,并且进一步说明了中医药古方配伍理论的科学性。     

经方中芍药配伍应用规律探析

考察《伤寒杂病论》经方中配伍应用芍药的61首经方（56首原方，5首加减方）及126条相关条文。通过对经方剂量、比例、配伍、病位主症的分析，认为：经方中芍药为白芍；白芍并非补血药，其益阴补血的功效是通过配伍实现；经方中"分"为计量单位；芍药在丸散汤中的常见用量；经方中芍药主治的症状包括四肢挛急、腹痛、烦满、下利、小便不利等。与不同药物配伍，作用部位与症状随之变化，常见配伍有桂枝、附子、甘草、柴胡、黄芩、枳实、当归、茯苓等。     

脉络学说营卫理论指导心律失常辨证论治

经脉包括经(气)络和血(脉)络,清代周学海《读医随笔》将气络末端称为"气之细络",脉络末端称为"血之细络"。心之气络涵盖心脏起搏与传导系统等广泛调控机制,心之脉络涵盖冠状动脉循环系统,心之气络与脉络相互协调,营卫相偕而行,共同维持心脏正常功能。各种致病因素导致营卫异常而发为心律失常,基于脉络学说营卫理论"损其心者,调其营卫"(《难经·十四难》)治疗原则指导心律失常辨证论治,同时充分结合现代致病因素和致病特点,分别选用调节卫气营血之方药,标本兼治,以期为临床诊疗提供有益借鉴。     

辛味中药在治疗消渴证中的应用价值及中药五味理论现代研究的思考

Learning to live with a hand nerve disorder: A constructed grounded theory

Study DesignGrounded theory.IntroductionThe broader perspective of health offered by the World Health Organization's International Classification of Functioning, Disability and Health has had a significant bearing on how we view the measurement of health outcomes after surgical or therapy interventions for peripheral nerve disorders affecting the hand. The value of the patient's perspective is now recognized and outcomes which reflect this are being advocated in the clinical management and support of this population.Purpose of the StudyThis qualitative study sought to explore the lived experience of a hand nerve disorder and in particular the impact on body structure/function, activities, and participation.MethodsIn depth, one-to-one interviews with 14 people with a range of hand nerve disorders were conducted. Constructivist grounded theory methods were used to collect and analyze the data. Patients were also given the option of taking photographs to visually represent what it is like to live with a nerve disorder, to bring with them for discussion during the interview.ResultsThe impact of hand nerve disorders forms part of a wider narrative on adaptation. A process of “struggling” and then “overcoming” was experienced. This was followed by an interior aspect of adaptation described as “accepting.” This gave rise to participants “transforming,” being changed as a result of the journey that they had been on.ConclusionsThis study provides an explanatory theory on the adaptive process following a hand nerve disorder which may inform future patient-therapist interactions.
