Filter by:The primary objective is to assess the safety and tolerability of samRNA vaccines GRT-R912, GRT-R914, and GRT-R918 when administered as prime and/or boost in healthy adult participants naïve to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), SARS-CoV-2 convalescent, previously vaccinated, or non-vaccinated participants, and people living with HIV (PLWH) or HIV-negative.
Observer-blind, randomized, active-controlled prospective intervention study
Aim of investigators was to study whether abnormalities of lung diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO) in long COVID may have a clinical impact in relation to exercise intolerance.
The primary objective of the study is to measure the anti-SARS-CoV-2 neutralizing antibody titres in adult participants, in particular elderly, so as to demonstrate immunogenic superiority of MVC-COV1901 to the active control, AZD1222 vaccine, in terms of the GMT of neutralizing antibodies at 14 days after the second dose of the study intervention. This study also assesses the safety and tolerability of the study intervention and explores the immunogenicity in terms of antigen-specific immunoglobulin as well as the potential efficacy of MVC-COV1901 in preventing COVID-19.
The aim of this study was to evaluate for the first time in the Gaza-strip the characteristics and incidence of Upper Extremity Trauma (UET) during the COVID-19 pandemic. The participants, investigated the characteristics of UET cases, and evaluated the UET primary medical-care. Additionally, also evaluate the obstacles in treating UET in Gaza during the COVID-19 pandemic.
Introduction: While there is a substantial body of knowledge about acute Covid-19 in children and young people (CYP), less is known about long-COVID, where symptoms continue beyond four weeks, particularly since the most recent wave of the Omicron variant and the UK childhood vaccination programme roll out. This study aims to provide a picture of longer-term effects of an acute Covid-19 infection in CYP and identify their needs. Methods and analysis: The study comprises an observational prospective cohort study and a linked qualitative study. The cohort study will identify CYP aged 8-17 years in the West Midlands of England and, irrespective of Covid-19 status, invite them to complete an online questionnaire at point of recruitment, and after 3, 6, 9 and 12 months. CYP who have experienced long-term effects of COVID-19 will be invited to interview and, those who are currently experiencing symptoms, will be invited to record their experiences in a diary. Adults working in professional or third sector/voluntary roles with CYP will be invited to take part in a focus group to explore the perceived impact of Long-COVID on the wider experience of CYP. Approximately 900 participants will be needed for the cohort study to ensure the sample size is suitable, with approximately 20 CYP invited to interview and approximately 8 professionals invited to a focus group. Descriptive statistics will be used to describe incidence rates of symptoms and symptom resolution trajectories, and comparisons made between exposed and non-exposed groups. Logistic regression models will be used to estimate associations between candidate predictors and development of Long-COVID at each follow-up point. Linear regression will be used to estimate associations between candidate predictors and poor outcome in terms of health-related quality of life, as described by the KIDSCREEN10. Qualitative data will be analysed thematically using the constant comparison method. Ethics and dissemination: Research Ethics Committee and Health Research Authority approvals will be sought. Information about where to seek support will be provided to participants to mitigate against risks of harm. Study findings will be presented at conferences and published in open access journals.
As the COVID-19 pandemic persists, a sizable proportion of the U.S. population remains unvaccinated and at high risk of death and serious illness from COVID-19. Vaccine hesitancy, fueled by the proliferation of vaccine misinformation on social media, is one factor contributing to lack of vaccination. Current attempts to overcome vaccine misinformation focus on correcting or debunking falsehoods. Although debunking strategies are important components to any public health campaign, communications must also address rationales for vaccine hesitancy that vary among individuals and communities, and directly address the gist of their concerns in an empathetic, non-judgmental manner. We will conduct a randomized controlled trial to test the effectiveness of empathic, relationship-building interactions relative to standard provision of information on social media to address COVID-19 vaccine hesitancy.
Easing the morbidity and economic burden of age-related diseases is one of the major medical challenges. One of the key obstacles to healthy ageing is immune senescence, including the failure of lymphocytes to respond adequately to infection, malignancy and vaccination. Infectious diseases remain the fourth most common cause of death among the elderly in the developed world. Moreover, the gain of chronic low-grade non-specific inflammation with age contributes to many age-related diseases. Our early work showed that autophagy, the main cellular bulk degradation pathway in the cell, prevents ageing of the immune system. In preclinical models we showed an age-related decline in T cell autophagy. We rejuvenated the immune system by restoring autophagy in T and B cells with the autophagy-inducing metabolite spermidine. Here we are asking for matched funds for a small human clinical trial to confirm that spermidine has the same effect when administered to humans. We will give the nutraceutical spermidine to human volunteers aged >65 years either during or after vaccination against SARS-CoV-2 or influenza to test improvement of vaccine responses, immune senescence and inflamm-aging. We will also confirm whether a novel pathway we discovered that links spermidine to autophagy operates in humans, allowing us to make more specific drugs in the future. This small study of 120 volunteers overall will pave the way for a larger clinical trial with spermidine or novel related drugs.
At the "Métropole Savoie" hospital, to deal with the daily influx of severe patients during the second wave of COVID-19, 23 patients had to be transferred away from their home city and far from their families as part of a medical evacuation (EVASAN). The purpose of the study is to investigate whether there is an association between medical evacuations and the occurrence of psychological disorders such as post-traumatic stress, anxiety or depression occurring within 6 to 10 months in families of evacuated patients. The investigators want to compare the prevalence of psychological disorders in the families of patients evacuated for a serious form of COVID-19 (cases) compared to that of families of patients not evacuated (controls) hospitalized for a serious form of COVID-19.
The risk of secondary infection is high in critical patients hospitalized with the diagnosis of COVID-19. Immunosuppressive treatments are commonly used in critical COVID-19 patients, and immune dysfunction and CMV reactivation can be unnoticed in these patients.
