ObjectivesMany young Canadians experience high levels of networked connectivity, which some suggest may negatively impact their health. Adult monitoring has not been shown to be an effective long-term strategy for supporting young people in healthy engagement with tech. In this study, we explore the benefits of empowering young people to set healthy goals and monitor themselves. We engage with Shapka’s (2019) critique of dual-systems theory, and consider the relationship between the neurological and behavioural systems in relation to adolescent internet use.MethodsUsing a youth participatory action research approach, we co-designed a project with six adolescents to explore the ways that their use of networked technologies was affecting their lives by disconnecting and observing how the lack of networked connectivity changed their experiences. The youth used a media diary to track their use of devices both before and after disconnecting.ResultsThe main benefit of disconnecting appeared to be having the opportunity to reflect on one’s own use of networked devices. This enabled the participants to reconnect in a more intentional way. Findings support Shapka’s speculation that dual-systems theory, with a focus on regulation, may not be the most useful way of supporting adolescents in developing healthy habits around their wired tech.ConclusionAdolescent experiences of networked technologies are complex, yet they are able to navigate this landscape with intelligent strategies. Their self-directed exploration of disconnection helped them to become reflexive practitioners who were able to revisit their use of networked technologies with new insights and self-control. 相似文献

IntroductionTraining through medical simulation allows for continuous learning under controlled conditions. Simulation-based training activities can be used simultaneously with other educational strategies to strengthen the attitudinal skills needed to develop an informed consent process in the context of health research.ObjectiveTo facilitate learning in undergraduate medicine students, and to evaluate their competences to carry out an informed consent process in a scenario that resembles reality.Materials and methodsIn this semi-longitudinal study, a simulation-based activity was conducted with 136 medical students of the fourth (Group A) and fifth year (Group B) of the Marist University of Mérida, in southern Mexico.ResultsThe mean score for both groups was 72.48 ± 1.05 (95% CI = 70.4–74.5); 86.2 ± 0.96 (95% CI = 84.2–88.0); and 77.7 ± 0.72 (95% CI = 76.3–79.1), in the pre-test, the simulation and the post-test, respectively. The students of group A self-evaluated their performance with 3.93/5.00, and those of Group B, 4.04/5.00.DiscussionThis study showed that Group A students did not score lower on simulation-based activity when compared to students in Group B, suggesting that before the fifth year of undergraduate medical education, students could properly develop an informed consent-process for health research if they receive early education about medical ethics and research bioethics. Issues related to bioethics in human health research can be included as soon as medical students initiate research methodology courses. 相似文献

目的观察中西医结合法治疗痰热蕴结型咽喉反流性疾病的临床疗效。方法选取2018年9月至2019年9月就诊于辽宁中医药大学附属医院耳鼻咽喉科的痰热蕴结型咽喉反流患者60例为研究对象,随机分为对照组和治疗组各30例。对照组采用口服埃索美拉唑镁肠溶片治疗,治疗组在对照组的基础上加服中药汤剂治疗,组成:瓜蒌子15 g、甘草10 g、蜜麻黄10 g、麦冬15 g、生石膏30 g、炒枳壳15 g、炒紫苏子15 g、川贝母2 g、清半夏15 g加减,疗程均为2个月。分别于治疗前和治疗后对患者进行电子喉镜检查,并且观察反流症状指数RSI和反流体征评分RFS量表评分变化,从而进行疗效评价。结果两组治疗均能改善患者症状,但观察组方案优于对照组。结论中西医结合法治疗痰热蕴结型咽喉反流患者疗效显著,大大的改善患者的症状,值得推广。 相似文献

PurposeAnnual low-dose CT (LDCT) screening in high-risk individuals has been recommended to detect lung cancer earlier and reduce mortality. The objective of this study was to identify demographic, financial, and health care factors associated with screening uptake in a population-based survey.MethodsData from the Lung Cancer Screening Module and core modules of the 2017 Behavioral Risk Factor Surveillance System, a population-based survey administered via cell phone and landline, were analyzed to examine demographic, health, and financial factors associated with screening uptake among the 10 states that administered the screening module. Weighted frequencies and confidence intervals (CIs) were produced, and weighted Wald χ2 tests were used to compare differences in screening utilization by patient characteristics. A multivariate logistic mixed-effects model was constructed, in which participant clustering by state was accounted for with a random intercept.ResultsThe uninsured were less likely to undergo LDCT screening (odds ratio [OR], 0.28; 95% CI, 0.12-0.65). LDCT screening uptake was higher for participants with chronic respiratory conditions (OR, 4.14; 95% CI, 2.33-7.35); those who were divorced, separated, widowed, or refused to answer (OR, 1.41; 95% CI, 1.05-1.86); those who had previous cancer diagnoses (OR, 1.90; 95% CI, 1.40-2.56); and those aged 65 to 69 years (OR, 1.23; 95% CI, 1.06-1.44) or 70 to 74 years (OR, 1.17; 95% CI, 1.00-1.37). Utilization also varied significantly across states.ConclusionsHaving a related health condition whereby participants were sensitized to the benefits of early screening (ie, another cancer diagnosis, presence of chronic respiratory conditions) and having insurance coverage were associated with higher LDCT screening uptake. Providers should engage LDCT-eligible patients through informed and shared decision making to increase preference-sensitive screening decisions. 相似文献

黄芪始载于《神农本草经》,有补气升阳、益卫固表,利水消肿,托毒生肌之效。被誉为补气健脾之要药,临床上常用于气虚乏力、脾虚泄泻等疾病,已为医者所熟知。近年来,研究学者围绕其补气、健脾、利水功效机制已有较全面的认识。然陶弘景在《本草经集注》首载黄芪"逐五脏间恶血",表明本品兼有活血作用。目前,对于本品活血作用机制阐释,中医常基于"补气活血""气行血行"理论进行论证,但并不等同于本品无活血作用。通过梳理历代本草文献中对黄芪的记载,发现其活血作用应用广泛。综合传统方剂与现代方剂中有关其活血作用的应用,本品在方中行活血通络、活血利水、活血扶正作用,尤能体现其活血作用。且现代药理学研究在有关瘀血病理指标的分子机制中,黄芪有很好的调控作用,表明黄芪有活血作用,但未深入探究,存在研究价值。该文从历代文献对黄芪活血功效的论述、黄芪活血作用的临床应用及现代药理学研究深入探讨其活血作用机制,以期扩展黄芪的临床应用范围,为临床治疗提供理论指导。 相似文献

ABSTRACTThis article analyses how the HIV care cascade, an analytical tool, has become a policy practice that determines the direction and content of international AIDS policy. It traces the development of the cascade through from its emergence around 2011 to its position framing global AIDS policy by 2018. The article distinguishes between the cascade model as a mapping tool and the care cascade as a policy that aims to end the AIDS epidemic. It then argues that the move from an analytical to a policy tool has important implications, both for the scope of policies and for policy-relevant research. It concludes by considering its implications in determining policy direction. The qualitative research that informs the article is based on published care cascade research and policy documents, and observations of the presentations and discussions at the 2012 and 2018 International AIDS Conferences (IAS). The article uses textual analysis to develop its argument. 相似文献

The speed and scale of the COVID-19 pandemic has highlighted the limits of current health systems and the potential promise of non-establishment research such as “DIY” research. We consider one example of how DIY research is responding to the pandemic, discuss the challenges faced by DIY research more generally, and suggest that a “trust architecture” should be developed now to contribute to successful future DIY efforts. 相似文献
