摘要： Background and Objectives Population aging has led to an increased interest in cognitive health and, in particular, the role that stress plays in cognitive disparities. This paper extends previous work by characterizing coronavirus disease 2019 (COVID-19) stress type prevalence and its association with cognitive health in metro-Detroit among Black, Middle Eastern/Arab (MENA), and White older *** Design and Methods Data come from a regionally representative sample of adults aged 65+ in metro-Detroit (N = 600; MENA n = 199; Black n = 205; White n = 196). We used generalized linear models to compare groups on sociodemographic, objective stress, and social stress indicators. Multiple group structural equation models evaluated whether COVID-19 stress predicted cognitive health and whether that association varied across racial/ethnic *** MENA and Black older adults reported higher levels of objective stress than Whites. There were no racial/ethnic group differences in social stress. More objective stress was associated with better cognitive health, and more social stress was associated with worse cognitive health. The positive effect of objective stress was especially apparent for White older *** and Implications Though it appears that minority stress was not exacerbated in the context of pandemic stress, links between greater objective stress and better cognitive health apparent among White older adults were not evident among MENA or Black older adults. Broadening health disparities research by including underrepresented populations allows us to elevate scientific knowledge by clarifying what is universal and what is unique about the stress process.

摘要： Evolution of SARS-CoV-2 variants emphasizes the need for multivalent vaccines capable of simultaneously targeting multiple strains. SCTV01E is a tetravalent COVID-19 vaccine derived from the spike protein of SARS-CoV-2 variants Alpha, Beta, Delta, and Omicron BA.1. In this double-blinded placebo-controlled pivotal efficacy trial (NCT05308576), the primary endpoint was vaccine efficacy (VE) against COVID-19 seven days post-vaccination in individuals without recent infection. Other endpoints included evaluating safety, immunogenicity, and the VE against all SARS-CoV-2 infections in individuals meeting the study criteria. Between December 26, 2022, and January 15, 2023, 9,223 individuals were randomized at a 1:1 ratio to receive SCTV01E or a placebo. SCTV01E showed a VE of 69.4% (95% CI: 50.6, 81.0) 7 days post-vaccination, with 75 cases in the placebo group and 23 in the SCTV01E group for the primary endpoint. VEs were 79.7% (95% CI: 51.0, 91.6) and 82.4% (95% CI: 57.9, 92.6), respectively, for preventing symptomatic infection and all SARS-CoV-2 infections 14 days post-vaccination. SCTV01E elicited a 25.0-fold higher neutralizing antibody response against Omicron BA.5 28 days post-vaccination compared to placebo. Reactogenicity was generally mild and transient, with no reported vaccine-related SAE, adverse events of special interest (AESI), or deaths. The trial aligned with the shift from dominant variants BA.5 and BF.7 to XBB, suggesting SCTV01E as a potential vaccine alternative effective against present and future variants. Here, the authors report results from a randomized, placebo-controlled phase 3 trial of the tetravalent SARS-CoV-2 protein vaccine SCTV01E, demonstrating a favorable efficacy profile during a time when predominant viral variants were changing from BA.5 and BF.7 to XBB.

摘要： Orthostatic intolerance (OI) is a key symptom of long COVID; however, the pathophysiology remains unknown. Among 688 long COVID patients who visited our clinic during the period from February 2021 to April 2023, 86 patients who were suspected of having OI and who underwent an active standing test (ST) were investigated to elucidate the clinical characteristics of OI in patients with long COVID. Of the 86 patients, 33 patients (38%) were ST-positive. Nausea and tachycardia in daily life were frequent complaints in the ST-positive group. The increase in heart rate (HR) during the ST was significantly greater during a 10-min period after standing in the ST-positive group (+ 30 bpm) than in the ST-negative group (+ 16 bpm). The initial increase in diastolic blood pressure (DBP) just after standing was significantly greater in the ST-positive group (+ 14 mmHg) than in the ST-negative group (+ 9 mmHg). Serum cortisol levels in the ST-positive patients aged over 20 years were higher and growth hormone levels in the patients under 20 years of age were lower than those in the ST-negative group. Autonomous nervous symptoms, transient DBP rise with increasing HR after standing, and endocrine dysfunctions are helpful for detecting OI related to long COVID.

摘要： Objectives: The aim of this study was to describe the effectiveness of the vaccines (Tozinameran and Sputnik V), administered on a convenience sample of healthcare workers, and also to describe the relationship between the levels of neutralizing antibodies (NAbs) and the type of vaccine used, as well as their association with incident cases during follow-up. Methods: The study included 262 participants, who underwent vaccination during the period from September 2021 until August 2022. For determining the levels of NAbs we used the CLIA based method, and all the samples were processed with the SNIBE Maglumi 800 analyzer. The patients were observed for one year for occurrence of incident infection. Results: The participants with prior SARS-CoV-2 positivity showed substantially higher titer of NAbs (8.86 vs. 0.94, p<0.001). The participants in the Gam-COVID-Vac group had median levels of NAbs of 1.57 (IQR 0.42-5.73), while they in the Tozinameran group showed substantially higher levels of 2.37 (IQR 0.9-6.27). The incident cases after immunization had substantially lower median values of NAbs when compared to the rest (0.48 vs. 3.97, p<0.001), and the interval between the second dose and the serological measurements were similar. Conclusions: The current study showed that the tested vaccines demonstrated vaccine effectiveness of over 50 % during the first year after the vaccination in a sample of health care workers. Although health care workers remain separate population group, when compared to the rest, the results could be extrapolated to populations with similar age and immune experience.

摘要： BackgroundDespite the end of the COVID-19 lockdown and reopening of schools, the long-term effects of quarantine on the weight status, eating habits, and lifestyle of children and adolescents remain unknown. This study aimed to determine the long-term effects of the lockdown on the weight status, eating habits, and lifestyle changes of children and adolescents in *** descriptive cross-sectional study was conducted from April to May 2022. The target population comprised one hundred students aged between 10 and 16 years old. Our study obtained students' weight and height data from records maintained by school principals or physical education instructors before and after the quarantine period. The BMI z-score (zBMI) was calculated for each time point. The researchers also provided a questionnaire to collect the students' demographic and lifestyle status changes during school *** found that the zBMI increased significantly from - 0.02 +/- 1.64 to 0.36 +/- 1.12, and the number of individuals with overweight and obesity increased by 3% during quarantine (P <= 0.05). These changes were more pronounced in males and students aged 14-16 years old. We also found that eating habits, sleeping time, sleeping patterns, screen time (time spent on social media per day), and physical activity had significant negative changes during quarantine, and a significant increase in zBMI was observed among students who experienced negative eating behaviors, altered sleeping patterns, and decreased physical activity during school *** prolonged school closures due to the COVID-19 lockdown aggravated students' health and lifestyle status, our findings can aid in proper planning to establish an appropriate framework for the diet, physical activity, and sleeping quality of students during extended school closures.

摘要： The COVID-19 pandemic urged all healthcare providers to collaborate to defeat this mortal infection. SARS-CoV-2 almost hits the respiratory system and may have subsequent serious complications like pulmonary embolism and multi-organ damage. To illustrate the rehabilitation program challenges encountered by physiotherapists in clinically managing hospitalized COVID-19 patients. The goal was to preclude the need for invasive mechanical ventilation and to improve the patient’s oxygen saturation and general health. In this retrospective case-series study, we described the physiotherapy strategies implemented for 14 COVID-19 patients during the hospitalization period at an Egyptian governmental quarantine hospital. The rehabilitation program was customized by physiotherapists to accommodate the specific circumstances, conditions, and acquired complications of individual patients. Patients were under the care of physiotherapists in both the COVID ward and ICU. Overcoming challenges such as patient reluctance, co-morbidities, and the effects of aging was a task faced by these healthcare professionals. Consequently, the program had to be modified to suit the unique needs of each patient. These tailored programs encompassed techniques such as percussion, positioning, range of motion, circulatory exercises, and respiratory exercises. The patients exhibited positive responses to their designated physical therapy program, experiencing improvements on various levels based on the progression of their individual cases. Physiotherapy has a major role in improving patient complications after being infected with COVID-19. In this desperate pandemic era, physiotherapists gave hospitalized patients support both psychologically and physically.

摘要： BackgroundThe Corona Virus Disease 2019 (COVID-19) pandemic overwhelmed health systems and disrupted the delivery of health services globally. Community Health Workers (CHWs) play a critical role in linking communities to health systems, supporting the prevention and control of diseases in many low- and middle-income countries. However, their roles, barriers, and facilitators in the response and control of the COVID-19 pandemic have not been well documented. We described the roles of CHWs in the COVID-19 response, including the barriers and *** cross-sectional study design was used to assess the COVID-19 response in the Democratic Republic of Congo (DRC), Nigeria, Senegal, and Uganda. This involved 110 key informant interviews with policymakers, health facility managers, district health managers, and CHWs to understand the role of CHWs in the COVID 19 response, selected purposively. The total sample size was based on information saturation in each of the countries. A document review on the COVID-19 response was also conducted. We searched Google, Google Scholar, and PubMed for published and grey literature. Data from the selected documents were extracted into a Google master matrix in MS Excel and analyzed *** COVID-19 Control, CHWs supported community-based surveillance, contact tracing, risk communication, community mobilization, and home-based care. To support the continuity of other non-COVID-19 services, the CHWs conducted community mobilization, sensitizations, outreaches, referrals, and patient follow-ups. CHWs were challenged by movement restrictions, especially in the initial stages of the lockdown, inadequate PPE, increased workload, low allowances, and motivation. CHW were facilitated by trainings, the development of guidelines, development partners' support/funding, and the provision of personal protective equipment (PPE) and *** supported both the COVID-19 control and continuity of non-COVID-19 healt

摘要： The pandemic meant a change in academic approach. This had an impact on the mental health of students, leading to, among other problems, depressive disorders. The aim of this study was to find out the prevalence and factors that favoured the development of depression in nursing students during the COVID-19 pandemic. A systematic review with meta-analysis of prevalence was conducted in October 2023, using Pubmed, CINAHL and Scopus as the data sources used for the search. This review followed the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Search equation was: "(undergraduate nurses OR nursing students) AND depression AND (COVID-19 OR Sars-CoV-2)". The final set of articles was N = 12. Quantitative primary studies using anonymous scales and surveys to assess the prevalence of depression in nursing students in the last 3 years were included. Studies show a high prevalence of depression among young university students with figures above 50%. The total sample of students in the meta-analysis was n = 4,479 with a prevalence value of 32% (CI95% 22%-42%). Affected students are characterised by young, female students. Concerns included generalised academic uncertainty, social isolation, work overload, fear of contagion and concern about teaching delivery. Coping mechanisms were generally resilience, spiritual support, laughter therapy, seeking information about COVID-19 and eating food. In conclusion, students, especially female students, are at high risk of depression due to social isolation. In addition, coping techniques were inadequate and future strategies to prevent this situation should be considered.

摘要： The COVID-19 pandemic influenced many changes to daily lifestyles, including public transportation ridership. To accommodate changes in ridership patterns, it is important to consistently update knowledge of the factors that most influence a rider’s decision to use public transportation. Origin-Destination Direct Ridership Models are one of the methods used to accomplish this, as they examine the sensitivity of transit demand to changes across a series of explanatory variables. This study replicated a time-of-day, multi-level Origin-Destination Land Use Ridership Model (OD-LURM), previously developed using 2014 ridership data and published in this journal, with 2022 SmarTrip card data from the Washington, D.C. Metrorail System. Comparing model results from 2014 and 2022, the magnitudes of the effects of various determinants on Metrorail ridership were examined, taking into account three different groups of variables at the level of origin stations, destination stations, and OD-station pairs. The effects of job-related variables, parking users, parking capacity, bus line counts, and median household income in AM peak, PM peak, and off-peak time periods were reduced compared to the previous study, sometimes drastically. The results also indicated a weaker model fit using the updated data. Overall, this replication study provides new context behind changes in post-pandemic ridership, and the results suggest persistent changes in travel behavior since the pre-pandemic period. The findings of this study could be used to inform transit oriented development, fare structures, and service levels in the D.C. metropolitan area post-pandemic. © 2024, The Authors.
