Filter by:The purpose of this research is to gather information to answer questions about the Coronavirus Disease 2019 (COVID-19) which is caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. This study will collect information and biological specimens from participants who have been tested for the SARS-CoV-2 infection. By doing this study, the investigators hope to learn important new information about SARS-CoV-2 infections and the potentially severe outcomes of COVID-19 to find better ways to manage and treat it in the future. The investigators also hope to learn what makes some people more susceptible to infection to help better inform Veterans on how to reduce their risk of infection. This study also involves the development and maintenance of a participant registry, a data repository, and a biorepository for future research.
The main aim of this study is to compare the effect of two non-invasive neuromodulation targets in patients meeting WHO criteria for the post-COVID condition. A randomized, parallel, double-blind study will be conducted. Patients will receive 15 neuromodulation sessions through transcranial electrical stimulation for 3 weeks, associated with cognitive stimulation during therapy. The main objective will be to evaluate the change in physical fatigue. As secondary objectives, changes in cognition, depression, pain, quality of sleep and quality of life will be evaluated. The objective of this study is to evaluate the effect of two targets (left dorsolateral prefrontal and M1) of the neuromodulation intervention, together with cognitive stimulation.
The objective of this trial is to compare the immunogenicity and the safety of the Beta-variant recombinant protein booster vaccine (VidPrevtyn® Beta, Sanofi) to a bivalent mRNA vaccine (Comirnaty Original/Omicron BA.4-5, BioNTech-Pfizer) in adults previously vaccinated with at least 3 doses of COVID-19 mRNA vaccine. The results will provide important data for the future COVID 19 vaccine strategy. A biobank will also be set up to evaluate the protection conferred by one or other of these vaccines as booster in the event of the emergence of new variants in the future.
The goal of this observational study is to measure the changes in the parameters of endocrine function and tissue sensitivity to hormones induced by SARs-CoV-2 infection. The main questions it aims to answer are: - Does SARs-CoV-2 infection causes endocrine dysfunctions? - Does the treatment of the underlying endocrine dysfunctions, improves the clinical outcome or the occurrence of late onset complications of SARs-CoV-2 infection? - Are patients with previously known endocrine diseases more fragile in case of SARs-CoV-2 infection? Participants will undergo blood testing and a physical examination at admission, during hospitalization at discharge and 3 and 6 moths after discharge They results will be compared to those of patients admitted for other reasons in order to assess whether the prevalence of endocrine dysfunctions is increased compared with controls.
In order to limit the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a significant numbers of measures were taken worldwide. It has been shown that the pandemic and its consequences, such as lockdown and isolation, can have a significant long-term impact on the well-being of children. This study follows the initial DYNAtracs study on SARS-CoV-2 transmission in primary schools. In Belgium, 2488 children and 444 school attenders in 11 primary schools of the Federation Wallonia Brussels are invited. Every participant will be invited to answer a well-being questionnaire. This study aimed to document the children and workers well-being in the primary schools of Belgium after the COVID-19 pandemic. The results of the study should contribute to improved decision making regarding measures for schools and children well-being in the context of current and future pandemics. The objective of this study is to document the well-being of children and workers after the COVID 19 pandemic in primary schools of the Federation Wallonia-Brussels.
The study examines changes in retinal oximetry in patients after COVID-19 disease. It aims to analyze and quantify possible retinal microvascular abnormalities that may result from possible post-inflammatory damage to the endothelium of the vessels associated with COVID-19 disease. Retinal vascular involvement may indicate similar changes in the vascular system in other organs.
Acute and chronic cardiovascular complications of pneumonia are common and result from various mechanisms, including relative ischemia, systemic inflammation, and pathogen-mediated injury. However, there is only limited published data regarding on cardiovascular desease (CV) submissions in the wake of viral outbreaks. Data collected during the COVID-19 pandemic highlighted a number of possible determinants of adverse outcome in these patients, particularly with reference to cardio-respiratory complications.
A randomized, double-blind, parallel-arm, phase II, explorative study investigating the efficacy and safety of orally administered N-Acetylcysteine (NAC) versus placebo in patients with history of SARS-Cov-2 infection and residual respiratory impairment.
The purpose of this trial is to evaluate immunogenicity and safety of CVXGA administered as a single intranasal dose against SARS-CoV-2 S-protein in participants. The trial will enroll up to 400 healthy participants, age 18-80 years.
A pilot Study To investigate the efficacy of a breathing intervention for improving persistent breathlessness due to dysregulated breathing following COVID-19 when compared to usual care.
