Substance use disorder has become an epidemic in the young adult population across the United States, and these numbers rose during the COVID-19 pandemic. Psychotherapy incorporating equine interaction has emerged to show promise in the mental health community as a complementary form of therapy for this age group and offered a viable treatment option during the pandemic due to the outdoor nature of the treatment environment. However, research concerning its use within a residential treatment program was lacking. The objective of this study was to evaluate the efficacy of psychotherapy incorporating equine interaction in a residential treatment program during the COVID-19 pandemic for developing an emotionally safe environment for learning for young adults. Participants (ages 18–25 years) were those in a substance abuse residential treatment program utilizing psychotherapy incorporating equine interaction during the COVID-19 pandemic. Participants were involved in weekly equine therapy for 2–7 weeks. Participants were divided according to length of stay at the residential facility and participation level with equine interactive activities. Assessment of emotional safety and long-term memory development was performed at the beginning and end of the treatment program. The development of memories centered around equine information that was covered during the treatment program. Semantic memory was assessed using a self-reporting knowledge exam and procedural memory was assessed using a skill evaluation. Emotional safety was determined using a self-reporting survey instrument. Paired t-tests determined significant improvement in emotional safety (p = 0.02) and semantic (p = 0.01) and procedural (p = 0.00) memory for all participants by the end of the program. The one-way analysis of variance indicated length of stay and participation level were not significant indicators of emotional safety (length of stay: p = 0.91, participation level: p = 0.98) and semantic (length of stay: p = 0.09, participation level: p = 0.60) and procedural (length of stay: p = 0.25, participation level: p = 0.09) memory development. These results suggest psychotherapy incorporating equine interaction was an efficient complementary therapeutic intervention for developing emotional safety and encouraging learning in a young-adult residential addiction treatment program during the COVID-19 pandemic.
物质使用障碍已成为美国年轻人中的一种流行病,在COVID-19大流行期间,这些数字有所上升。结合马的相互作用的心理治疗已经出现,在精神卫生界显示出希望,作为对这一年龄组的补充治疗形式,并且由于治疗环境的户外性质,在大流行期间提供了一种可行的治疗选择。然而,关于其在住宅治疗方案中的应用的研究是缺乏的。本研究的目的是评估在2019冠状病毒病大流行期间,将马互动纳入住院治疗项目的心理治疗效果,为年轻人创造一个情感安全的学习环境。参与者(年龄在18-25岁)是在COVID-19大流行期间使用包含马互动的心理治疗的药物滥用住院治疗项目中的参与者。参与者每周接受马术治疗2-7周。参与者根据在住宅设施的停留时间和参与马互动活动的程度进行划分。在治疗方案开始和结束时进行情绪安全和长期记忆发展评估。记忆的发展以马的信息为中心,在治疗计划中被覆盖。语义记忆采用自我报告知识测验评估,程序记忆采用技能测验评估。使用自我报告调查工具确定情绪安全。配对t检验表明,到项目结束时,所有参与者的情绪安全(p = 0.02)、语义记忆(p = 0.01)和程序记忆(p = 0.00)都有了显著改善。单因素方差分析显示,留院时间和参与水平对情绪安全(留院时间:p = 0.91,参与水平:p = 0.98)、语义记忆(留院时间:p = 0.09,参与水平:p = 0.60)和程序记忆(留院时间:p = 0.25,参与水平:p = 0.09)发展无显著影响。这些结果表明,在2019冠状病毒病大流行期间,纳入马互动的心理治疗是一种有效的补充治疗干预措施,可用于培养年轻人的情绪安全和鼓励学习。

Given the variability in inflammatory responses to SARS-CoV-2 infection observed within human populations, we aimed to develop an in vitro model system (based on monocyte-macrophages, a key relevant cell type) that could yield insights regarding the impact of rs2228145, a clinically relevant polymorphism within the coding region of a key inflammatory gene in the body’s response to SARS-CoV-2 infection: the interleukin-6 receptor (IL-6R) gene. Three monocyte-macrophage cell-lines (U937, THP-1, MM6) were shown to exhibit AA, AC and CC rs2228145 genotypes, respectively, and to exhibit an MM6 > THP-1 > U937 pattern regarding basal levels of soluble IL-6R (sIL-6R) release. Similar MM6 > THP-1 > U937 patterns were seen regarding the extents to which (i) circulating levels of the IL-6/sIL-6R ‘active complex’ increased and (ii) phosphorylation of the downstream transcription-factor STAT3 occurred, following treatment with SARS-CoV-2 spike protein (SP). Moreover, a blocking antibody for the ACE-2 entry receptor for SARS-CoV-2 suppressed effects (i) and (ii), suggesting that interaction between SP and ACE-2 is the initial event that triggers IL-6/IL-6R signalling in our system. Production of IL-8 occurred to greater extents in A549 lung epithelial cells treated with tissue-culture supernatants from SP-treated MM6 cultures than SP-treated THP-1 or U937 cultures. Our data indicate that the rs2228145 genotype significantly impacts upon SP-associated IL-6/sIL-6R signalling in vitro, suggesting that it may influence in vivo risk of developing severe COVID-19 and/or long-COVID symptoms following infection by SARS-CoV-2. Thus, the rs2228145 genotype may have potential as a biomarker that differentiates between patients at risk of developing severe and/or prolonged symptoms following infection by SARS-CoV-2 and those who are at less risk.
鉴于在人群中观察到的对SARS-CoV-2感染的炎症反应的可变性,我们旨在开发一种体外模型系统(基于单核细胞-巨噬细胞,一种关键的相关细胞类型),该系统可以深入了解rs2228145的影响,rs2228145是人体对SARS-CoV-2感染反应的关键炎症基因编码区域内的临床相关多态性:白细胞介素-6受体(IL-6R)基因。三种单核巨噬细胞细胞系(U937, THP-1, MM6)分别表现出AA, AC和CC rs2228145基因型,并表现出MM6 >THP-1祝辞关于可溶性IL-6R (sIL-6R)释放基础水平的U937模式。类似的MM6 >THP-1祝辞在使用SARS-CoV-2刺突蛋白(SP)治疗后,在以下程度上观察到U937模式(i) IL-6/sIL-6R“活性复合物”的循环水平增加和(ii)下游转录因子STAT3的磷酸化发生。此外,针对SARS-CoV-2的ACE-2进入受体的阻断抗体抑制了效应(i)和(ii),这表明SP和ACE-2之间的相互作用是触发我们系统中IL-6/IL-6R信号传导的初始事件。与sp处理过的THP-1或U937培养物相比,sp处理过的MM6培养物的组织培养上清处理过的A549肺上皮细胞产生IL-8的程度更高。我们的数据表明,rs2228145基因型在体外显著影响sp相关的IL-6/sIL-6R信号传导,这表明它可能影响SARS-CoV-2感染后出现严重COVID-19和/或长时间COVID-19症状的体内风险。因此,rs2228145基因型可能有潜力作为区分感染SARS-CoV-2后出现严重和/或长期症状风险的患者和风险较低的患者的生物标志物。

University students may have experienced heightened levels of stress during the COVID-19 pandemic; however, less is known about coping mechanisms (i.e., approach and avoidance) that were used to manage such stress. Further, there is a need to identify groups of students who may have been at elevated risk for stress. The present study examined the association between coping and perceived stress and whether there were differences in stress based on sociodemographic factors and COVID-19-related changes in employment, housing, and income. Data were collected from 150 university students between the ages of 18 and 25 years (M = 20.68; SD = 1.73). Results indicated that those who endorsed more approach coping skills had lower levels of stress and those who endorsed more avoidance coping skills had higher levels of stress. Additionally, females, those who lost income, and non-heterosexual individuals endorsed higher levels of stress. The results demonstrate the importance of targeted discussions with university students regarding stressors and coping mechanisms.
在2019冠状病毒病大流行期间,大学生可能经历了更大的压力;然而,人们对用来管理这种压力的应对机制(即接近和回避)知之甚少。此外,有必要确定哪些学生可能有较高的压力风险。本研究调查了应对和感知压力之间的关系,以及基于社会人口因素和与covid -19相关的就业、住房和收入变化,压力是否存在差异。数据收集自150名年龄在18至25岁之间的大学生(M = 20.68;Sd = 1.73)。结果表明,采用更接近的应对技巧的人压力水平较低,而采用更回避的应对技巧的人压力水平较高。此外,女性、失去收入的人以及非异性恋者的压力水平更高。结果表明,与大学生就压力源和应对机制进行针对性讨论的重要性。

Vaccination against infectious disease affords direct protection from vaccine-induced immunity and additional indirect protection for unvaccinated persons. A systematic review was conducted to estimate the indirect effect of COVID-19 vaccination. From PubMed and Embase, 31 studies were included describing the impact of original wild-type COVID-19 vaccines on disease transmission or viral load. Overall, study results showed the effectiveness of COVID-19 vaccination against SARS-CoV-2 transmission (range 16–95%), regardless of vaccine type or number of doses. The effect was apparent, but less pronounced against omicron (range 24–95% for pre-omicron variants versus 16–31% for omicron). Results from viral load studies were supportive, showing SARS-CoV-2 infections in vaccinated individuals had higher Ct values, suggesting lower viral load, compared to infections among the unvaccinated. Based on these findings, well-timed vaccination programs may help reduce SARS-CoV-2 transmission—even in the omicron era. Whether better-matched vaccines can improve effectiveness against transmission in the omicron era needs further study.
预防传染病的疫苗接种可直接防止疫苗引起的免疫,并为未接种疫苗的人提供额外的间接保护。对COVID-19疫苗接种的间接效果进行了系统评价。来自PubMed和Embase的31项研究描述了原始野生型COVID-19疫苗对疾病传播或病毒载量的影响。总体而言,研究结果显示,无论疫苗类型或剂量多少,COVID-19疫苗接种对SARS-CoV-2传播的有效性(范围为16-95%)。这种影响是明显的,但对组粒变异的影响不那么明显(组粒前变异的范围为24-95%,而对组粒变异的范围为16-31%)。病毒载量研究的结果是支持性的,显示接种疫苗的个体感染SARS-CoV-2的Ct值较高,表明与未接种疫苗的感染相比,病毒载量较低。基于这些发现,及时的疫苗接种计划可能有助于减少SARS-CoV-2的传播,即使在微米时代也是如此。更好匹配的疫苗是否能提高在微米时代对抗传播的有效性还需要进一步研究。

Objectives: There is a lack of knowledge about the challenges of researchers who continued in-person research during the early phases of the COVID-19 pandemic. Design: Electronic survey assessing work-related exposure to COVID-19, logistical challenges, and procedural changes during the first year of the COVID-19 pandemic on clinical research. Setting: National Heart, Lung, and Blood Institute-sponsored Prevention and Early Treatment of Acute Lung Injury Clinical Trial Network Centers. Subjects: Research staff at research Network Sites. Measurements and Main Results: The 37-question survey was completed by 277 individuals from 24 states between 29 September 2020, and 12 December 2020, yielding a response rate of 37.7%. Most respondents (91.5%) indicated that non-COVID-19 research was affected by COVID-19 research studies. In response to the COVID-19 pandemic, 20% of respondents were reassigned to different roles at their institution. Many survey takers were exposed to COVID-19 (56%), with more than 50% of researchers requiring a COVID-19 test and 8% testing positive. The fear of infection was 2.7-times higher compared to pre-COVID-19 times. Shortages of personal protective equipment were encountered by 34% of respondents, primarily due to lack of access to N95 masks, followed by gowns and protective eyewear. Personal protective equipment reallocation from research to clinical use was reported by 31% of respondents. Most of the respondents (88.5%), despite these logistical challenges, indicated their willingness to enroll COVID-19 patients. Conclusions: During the first year of the COVID-19 pandemic, members of the research network were engaged in COVID-19 research despite logistical challenges, limited access to personal protective equipment, and fear of exposure. The research network’s survey experience can inform ongoing policy discussions to create research enterprises that can dexterously refocus research to address the knowledge gaps associated with novel public health emergencies while mitigating the effect of pandemics on existing research projects and research personnel.
目的:人们对在COVID-19大流行的早期阶段继续进行现场研究的研究人员所面临的挑战缺乏了解。设计:电子调查,评估与工作相关的COVID-19暴露情况、后勤挑战以及临床研究中COVID-19大流行第一年的程序变化。环境:国家心肺血液研究所资助的急性肺损伤预防和早期治疗临床试验网络中心。研究对象:研究网络站点的研究人员。测量和主要结果:来自24个州的277名个人在2020年9月29日至2020年12月12日期间完成了37个问题的调查,回复率为37.7%。大多数受访者(91.5%)表示,非COVID-19研究受到COVID-19研究的影响。为应对COVID-19大流行,20%的受访者被重新分配到所在机构的不同角色。许多受访者(56%)接触过COVID-19,超过50%的研究人员需要进行COVID-19检测,8%的研究人员检测呈阳性。对感染的恐惧是新冠肺炎前的2.7倍。34%的答复者遇到个人防护装备短缺的问题,主要原因是无法获得N95口罩,其次是防护服和防护眼镜。31%的答复者报告了个人防护装备从研究重新分配到临床使用的情况。尽管存在这些后勤挑战,但大多数受访者(88.5%)表示愿意招募COVID-19患者。结论:在2019冠状病毒病大流行的第一年,尽管面临后勤挑战、个人防护装备有限以及害怕接触,研究网络成员仍参与了2019冠状病毒病的研究。该研究网络的调查经验可以为正在进行的政策讨论提供信息,以创建研究企业,这些企业能够灵活地重新调整研究重点,以解决与新型公共卫生紧急情况相关的知识空白,同时减轻流行病对现有研究项目和研究人员的影响。

We provide policy lessons for governments across Latin America by drawing on an original dataset of daily national and subnational non-pharmaceutical interventions (NPIs) during the COVID-19 pandemic for eight Latin American countries: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Mexico, and Peru. Our analysis offers lessons for health system decision-making at various levels of government and highlights the impact of subnational policy implementation for responding to health crises. However, subnational responses cannot replace coordinated national policy; governments should emphasize the vertical integration of evidence-based policy from national to local levels while tailoring local policies to local conditions as they evolve. Horizontal policy integration across sectors and jurisdictions will also improve coordination at each level of government. The Latin American experiences with policy and politics during the COVID-19 pandemic project glocal health policy recommendations that connect global considerations with local needs.
我们利用阿根廷、玻利维亚、巴西、智利、哥伦比亚、厄瓜多尔、墨西哥和秘鲁这八个拉丁美洲国家在2019冠状病毒病大流行期间每日国家和地方非药物干预措施的原始数据集,为拉丁美洲各国政府提供政策经验。我们的分析为各级政府的卫生系统决策提供了经验教训,并突出了地方政策实施对应对卫生危机的影响。然而,次国家层面的应对不能取代协调一致的国家政策;各国政府应强调从国家层面到地方层面的循证政策的纵向整合,同时根据当地情况调整地方政策。跨部门和辖区的横向政策整合也将改善各级政府的协调。拉丁美洲在2019冠状病毒病大流行期间的政策和政治经验项目是将全球考虑与当地需求联系起来的全球卫生政策建议。

Institutional quarantine was one of the key public health measures used to control the spread of the Corona Virus Disease 2019 (COVID-19). Institutional quarantine has been associated with several psychosocial and economic risks. However, little is known about the psychosocial and economic risks it poses to affected persons in low-resource countries since it is a relatively new strategy for controlling disease spread in these settings. This article provides insights into the economic and psychosocial risks encountered by affected persons in a low-resource context. Narrative interviews were conducted with 20 adults placed under institutional quarantine to contain the COVID-19 pandemic in Uganda. Individuals confined in institutional quarantine experienced an intricate range of economic and psychosocial risks including loss of livelihood and/or income, financial distress, fear, worry, anger, loneliness, and stigma. The experience of specific risks was shaped by an intersection between individual and contextual factors. However, disregard for economic and social issues and shortcomings in the implementation of institutional quarantine contributed profoundly to the occurrence of risks. Safety nets to address the emergent financial insecurities of quarantined individuals and their families and bridging gaps in the implementation of institutional quarantine may help to minimise the associated economic and psychosocial risks in Uganda and similar contexts.
机构隔离是用于控制2019冠状病毒病(COVID-19)传播的关键公共卫生措施之一。机构隔离与若干社会心理和经济风险有关。然而,由于这是在这些环境中控制疾病传播的一种相对较新的战略,因此对它对资源匮乏国家的受影响者构成的社会心理和经济风险知之甚少。这篇文章提供了在低资源环境下受影响的人所遇到的经济和社会心理风险的见解。对乌干达为控制COVID-19大流行而被隔离的20名成年人进行了叙述性访谈。被限制在机构隔离中的个人经历了一系列复杂的经济和社会心理风险,包括失去生计和/或收入、经济困难、恐惧、担忧、愤怒、孤独和耻辱。对特定风险的体验是由个人因素和环境因素之间的交集形成的。然而,对经济和社会问题的忽视以及制度隔离实施中的缺陷,深刻地促成了风险的发生。建立安全网,解决被隔离者及其家庭出现的经济不安全感问题,弥合机构隔离实施中的差距,可能有助于最大限度地减少乌干达和类似情况下相关的经济和社会心理风险。

The emergence of SARS-CoV-2, the virus responsible for the COVID-19 pandemic, has sparked intense research on its spike protein, which is essential for viral entrance into host cells. Viral reproduction and transmission, host immune response regulation, receptor recognition and host cell entrance mechanisms, as well as structural and functional effects have all been linked to mutations in the spike protein. Spike protein mutations can also result in immune evasion mechanisms that impair vaccine effectiveness and escape, and they are linked to illness severity and clinical consequences. Numerous studies have been conducted to determine the effects of these mutations on the spike protein structure and how it interacts with host factors. These results have important implications for the design and development of medicines and vaccines based on spike proteins as well as for the assessment of those products’ efficiency against newly discovered spike protein mutations. This paper gives a general overview of how spike protein mutations are categorized and named. It further looks at the links between spike protein mutations and clinical outcomes, illness severity, unanswered problems, and future research prospects. Additionally, explored are the effects of these mutations on vaccine effectiveness as well as the possible therapeutic targeting of spike protein mutations.
导致COVID-19大流行的SARS-CoV-2病毒的出现引发了对其刺突蛋白的激烈研究,该蛋白对病毒进入宿主细胞至关重要。病毒的繁殖和传播、宿主免疫反应调节、受体识别和宿主细胞进入机制以及结构和功能影响都与刺突蛋白的突变有关。刺突蛋白突变还可能导致免疫逃避机制,从而损害疫苗的有效性和逃逸,并且它们与疾病严重程度和临床后果有关。已经进行了大量的研究来确定这些突变对刺突蛋白结构的影响以及它如何与宿主因子相互作用。这些结果对基于刺突蛋白的药物和疫苗的设计和开发以及评估这些产品对抗新发现的刺突蛋白突变的效率具有重要意义。本文概述了刺突蛋白突变是如何分类和命名的。它进一步研究了刺突蛋白突变与临床结果、疾病严重程度、未解决的问题和未来研究前景之间的联系。此外,还探讨了这些突变对疫苗有效性的影响以及刺突蛋白突变的可能治疗靶向性。

The objective of this study was to explore the potential enhancement of response within GP medical centres in New Zealand when facing heightened healthcare demand during a pandemic. This investigation sheds light on effective crisis management and leadership. By elucidating the contributions of this research, we gain a deeper appreciation of its importance in advancing our understanding of pandemic management. This study has yielded fresh insights and knowledge, beneficial to both academic and real-world applications, particularly concerning the adoption and effects of leadership and management within the healthcare domain amidst crisis situations. Using a multiple case study design, we conducted 86 in-depth interviews with staff from 16 General Practice centres in New Zealand. The critical activities delivered during the first six months of the COVID pandemic to keep New Zealand communities safe during the initial COVID-19 outbreak were (a) leadership in health service planning, including workforce planning, new operational processes, and expansion in the use of Information Communication Technology systems by the GP medical centres; (b) environment disinfection using national guidelines, education and establishment of respiratory clinics and expanding testing sites in GP medical centres; and (c) education and outreach to the patients including the protection of Māori, Pasifika, and remote communities. The decision to adopt a localised response to the pandemic, centralise testing, and better understand local-level needs prompted GP medical centres to communicate and engage early and effectively with patients. This enabled centres to lead and manage the COVID-19 pandemic with greater efficiency in the first six months of the outbreak. The New Zealand government’s “team of 5 million” COVID-compliance campaign program provided clear and persistent communication by the Ministry of Health. This campaign assisted in a better national understanding and compliance with the regulation of the COVID-19 pandemic. The dedication of medical centre managers to forward planning using contingency and accrued funding and setting up Community-Based Assessment Centres and respiratory clinics, including walk-in and outreach services, proved to be highly effective. GP centres led the way in COVID-19 pandemic planning, response, and management.
本研究的目的是探讨潜在的提高反应在全科医生医疗中心在新西兰面临在大流行期间提高医疗保健需求。这项调查揭示了有效的危机管理和领导。通过阐明这项研究的贡献,我们对其在促进我们对大流行管理的理解方面的重要性有了更深的认识。这项研究产生了新的见解和知识,有利于学术和现实世界的应用,特别是在危机情况下医疗保健领域的领导和管理的采用和影响方面。采用多案例研究设计,我们对新西兰16个全科医疗中心的工作人员进行了86次深度访谈。在COVID-19大流行的前六个月,为在COVID-19最初爆发期间确保新西兰社区的安全而开展的关键活动是:(a)在卫生服务规划方面发挥领导作用,包括人力规划、新的业务流程和全科医生医疗中心扩大使用信息通信技术系统;(b)使用国家指导方针进行环境消毒,开展教育并建立呼吸道诊所,扩大全科医生医疗中心的检测点;(c)对患者进行教育和外联,包括保护Māori、帕西菲卡和偏远社区。采取局部应对大流行、集中检测和更好地了解地方需求的决定,促使全科医生医疗中心尽早有效地与患者沟通和接触。这使各中心能够在疫情暴发的头六个月以更高的效率领导和管理COVID-19大流行。新西兰政府的“500万团队”covid - 19合规运动项目提供了卫生部明确和持续的沟通。这一运动有助于更好地在全国范围内了解和遵守COVID-19大流行的监管规定。医疗中心管理人员致力于利用应急和应计资金进行前瞻性规划,并设立社区评估中心和呼吸道诊所,包括上门服务和外联服务,证明非常有效。全科医生中心在COVID-19大流行规划、应对和管理方面处于领先地位。

Public market workers may be disproportionally exposed to SARS-CoV-2 due to interactions with shoppers. We aimed to estimate the seroprevalence of SARS-CoV-2 and determine whether occupation or adherence to preventive practices were associated with exposure. From July to December 2021, we longitudinally surveyed two Guatemalan markets twice. We collected blood to detect anti-S IgA, anti-S IgG, and anti-N IgG using ELISA, and a nasopharyngeal swab to detect SARS-CoV-2 using rRT-PCR. We estimated seroprevalences and assessed associations using generalized estimating equations. Of 229 workers, 109 (48%) participated in the first survey and 87 (38%) in the second. At baseline, 77% were female, 64% were aged <40, and 81% were vendors. Overall, the seroprevalence increased between surveys (61% to 89% for anti-S IgA, 53% to 91% for anti-S IgG, and 22% to 29% for anti-N IgG), but the magnitude differed by vaccination status and antibody type. The prevalence of infections decreased from 13% to 1% and most were asymptomatic. Vendor occupation was associated with IgA and IgG anti-S in males but not females. Using a mask was a protective measure. Most market workers had been exposed to SARS-CoV-2, possibly through asymptomatic individuals. Masking is a protective measure to be prioritized during high transmission.
由于与购物者的互动,公共市场工作人员可能不成比例地暴露于SARS-CoV-2。我们的目的是估计SARS-CoV-2的血清患病率,并确定职业或遵守预防措施是否与暴露有关。从2021年7月到12月,我们对危地马拉的两个市场进行了两次纵向调查。采用ELISA法采集血液检测抗s IgA、抗s IgG和抗n IgG,采用rRT-PCR法采集鼻咽拭子检测SARS-CoV-2。我们使用广义估计方程估计血清患病率和评估相关性。229名员工中,109人(48%)参加了第一次调查,87人(38%)参加了第二次调查。在基线时,77%为女性,64%为40岁,81%为供应商。总体而言,血清阳性率在调查期间有所增加(抗s IgA为61%至89%,抗s IgG为53%至91%,抗n IgG为22%至29%),但其幅度因疫苗接种状况和抗体类型而异。感染的流行率从13%下降到1%,并且大多数是无症状的。卖主职业与男性IgA和IgG抗s相关,而女性不相关。戴口罩是一种保护措施。大多数市场工作人员可能通过无症状个体接触过SARS-CoV-2。屏蔽是高传输时优先考虑的保护措施。
