Filter by:The objective of the clinical study is to evaluate the tolerability, safety, immunogenicity and prophylactic efficacy of the EpiVacCorona vaccine in volunteers aged 18 and above. The study tasks are to: - evaluate the safety of the EpiVacCorona vaccine when administered twice intramuscularly; - evaluate the tolerability of the EpiVacCorona vaccine when administered twice intramuscularly; - identify any adverse events to the administration of the EpiVacCorona vaccine; - investigate the humoral immune response following two doses of the EpiVacCorona vaccine; - investigate the cell-mediated immune response following two doses of the EpiVacCorona vaccine; - evaluate the prophylactic efficacy of the EpiVacCorona vaccine when administered twice intramuscularly.
This is a Phase II study designed to investigate if the Covid 19 vaccines are capable of eliciting production of antibodies against S protein of Sar-S-Cov-2 virus among patients with medical history of cancer previously treated with monoclonal anti CD-20 antibodies. The antibody production is defined based on the detection of antibodies in the serologic Covid-19 rapid test against S protein or with semiquantitative assay when it becomes available.
This is a phase 2 study in which subjects with coronavirus disease 2019 (COVID-19) will receive VIR-7831 (Sotrovimab) Generation 1 (Gen1) or VIR-7831 (Sotrovimab) Generation 2 (Gen2) and will be assessed for safety, tolerability, and pharmacokinetics.
Social technologies for health have already become essential means for providing underserved populations greater social connectedness and increased access to novel health information. However, these technologies have also had negative unintended consequences. The resulting digital divide in social technology takes many forms - from explicit racism that excludes African American and Latinx populations from the resources enjoyed by White and Asian members of online communities, to self-segregation for the purposes of identity preservation and community-building that unintentionally results in limited informational diversity in underserved communities. The result is an often unnoticed, but highly consequential compounding of inequities. This research seeks to use an online social network approach to address these challenges, in which the investigators demonstrate how reducing the online levels of network centralization and network homophily among African American community members directly increases their productive engagement with health-promoting information.
The COVID-19 pandemic has caused changes in health care during pregnancy, childbirth and postpartum. Although adverse effects of COVID-19 on perinatal mental health have been documented, changes in the perinatal mental health care provided to women and their families are yet to be established. As a Task Force in Perinatal mental health and COVID-19 pandemic within RISEUP-PPD COST Action, we aim: (i) to identify policies, guidelines and protocols from different European countries concerning the provision of perinatal mental health care in face of COVID-19, and (ii) to select the best practices to alleviate the negative impact of COVID-19 on perinatal mental health. The survey will be conducted among experts in perinatal mental health who are members of the COST Action RISEUP-PPD and COST Action Devotion in 36 European countries. The experts will fill in the online survey designed for this study that includes a series of open-ended questions, checklists, and response ratings on a 7-point scale. The topic areas cover seven domains of interest: 1) mental health policies, guidelines, protocols, and documents; 2) mental health care practices; 3) best practices; 4) barriers; 5) resources; 6) benefits; and 7) short- and long-term expectations. Data analysis will be mainly a qualitative analysis of the experts' professional views and opinions about the policies, guidelines, protocols, and documents regarding perinatal mental health changes in their country. Additionally, a basic quantitative descriptive analysis will be conducted.
A new coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) appeared in Wuhan, China and it arrived to Europe 2-3 months later. It infected millions of persons and led to the death of thousands until May 2020 where numbers of infections per week decreased significantly. However, starting September, number of infections started to escalate again and continued to rise until now. Hundreds of good quality articles were published during this period to study the relationship and effects of this virus on pregnancy and vice versa, as well as to determine the adverse neonatal and obstetrical outcomes following the infection. In a case-control study using propensity score matching at the level of age, body mass index and comorbidities (diabetes, hypertension, asthma), pregnant women over 20 week's gestation had significantly higher risk for intensive care unit stay, endotracheal intubation, hospitalization for disease related symptoms and need for oxygen therapy. A new systematic review also demonstrated increased risk for ICU admission in pregnant women compared to non-pregnant women and to non-infected pregnant women. On the other hand, many researchers have demonstrated that the rates of preterm delivery and cesarean delivery have increased as well, others reported a close relation between SARS-CoV2 infection and preeclampsia or preeclampsia like condition. Enormous effort was done in order to understand adverse outcomes related to this infection, however, most studies included patients in the third or late second trimester. Few studies stratified adverse outcomes of the patients according to the trimester of infection.
The COVID-19 pandemic is a challenge for the French healthcare system, particularly among the elderly due to their particular vulnerability to the serious consequences of the disease, with an estimated mortality rate of around 30-35% among the frail elderly. The management of the health crisis could take a new turn in 2021 with the arrival in France of vaccines against the SARS-CoV-2 virus. The objectives of this vaccination campaign are to reduce the morbi-mortality attributable to COVID-19 on the one hand, and to maintain essential activities related to the functioning of the country on the other hand and in particular the health system. However, the distrust of vaccination, traditionally strong in France, could have a negative impact on this strategy. While the President of the Republic announced on November 24, 2020 that vaccination against SARS-CoV-2 would not be made compulsory, almost one French person in two declared in several surveys that they did not want to be vaccinated; the main criterion for acceptance of vaccination being advanced age (the older they are, the more French people declare accepting to be vaccinated). In view of the gradual vaccine supply schedule for the year 2021, the French National Authority for Health established at the end of 2020 a prioritization by vaccine availability phases. The critical initial supply phase,which is currently taking place, is the one during which residents of retirement home and long-term care units are prioritized because of their particular vulnerability (age and co-morbidities) and their increased exposure to SARS-CoV-2. For these reasons, and in order to carry out the current vaccination campaign in the most optimal way possible, this national survey is launching to evaluate the acceptance rate of the SARS-CoV-2 vaccine among people living in retirement homes and long-term care units, to understand the mechanisms of acceptance or rejection, and to draw up an initial large-scale inventory of the symptoms observed following vaccination.
This protocol focuses on the seroprevalence in primary care health care providers (PHCPs) in Belgium. PHCPs manage the vast majority of COVID-19 and other patients and therefore are essential to organize health care efficiently. Currently however, evidence is lacking on 1. how many PHCPs get infected or diseased in Belgium, 2. the rate at which this happens, 3. their clinical spectrum, 4. their risk factors, 5. the effectiveness of the measures to prevent this from happening and 6. the accuracy of the immunological serology-based point-of-care test in a primary care setting. This study will be set up as a prospective cohort study. All Belgian GPs in clinical practice will be invited to register online for participation in this national epidemiological study and will be asked to invite the other PHCPs in their practice to do the same. A model and demography-informed sample of registered GPs and other PHCPs will be selected. These participants will be asked at each testing point to perform a capillary blood sample antibody point of care test (OrientGene®) and complete an online questionnaire. All data analysis will be performed and reported after each relevant testing period and at the end of the study.
To investigate the predictive role of lymphocyte subsets and other laboratory measurements in adult patients with COVID-19.This was a single center, retrospective study that involved adult patients with confirmed diagnosis of COVID-19. Electronic medical records were reviewed. Data including age, sex, symptom from onset to hospital admission and laboratory findings at admission of hospitalized patients with confirmed COVID-19 were extracted and analyzed retrospectively.This study indicates that the levels of lymphocyte subsets (CD4+, and CD8+) are associated with disease progression and severity, along with prognosis in patients with COVID-19.
The COVIDOUT study will prospectively investigate the serological immunity of outpatient cancer patients to evaluate the prevalence of previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and dependency of serological immunity on systemic (chemo)therapy after COVID19 disease as well as after vaccination.
