Filter by:The primary goal of the VIRIONUM project is to analyze the association of clinical, socio-demographic characteristics of patients and their genetic polymorphism, inflammatory and other biochemical markers with disease progression and death in subjects with COVID-19 disease. The research is an observational, cohort study with nested-case control design, including adult, male and female COVID-19 inpatients. Primary dependent variable will be outcome of disease, defined as discharge from the hospital or death. The outcomes and putative risk factors will be analyzed using binary logistic regressions. The proposed multi- and inter-disciplinary study should provide additional scientific evidence about risk factors for the development of severe forms of the disease and the COVID-19-related death.
Healthcare workers and COVID-19 patients may experience psychological distress consequent to the pandemic, and are at particularly elevated risk for experiencing posttraumatic stress disorder (PTSD), based on evidence from previous infectious disease outbreaks. The best-validated treatment for PTSD is exposure therapy. Exposure therapy help patients suffering from PTSD to revisit and overcome their traumatic experiences. Including virtual reality in exposure therapy has a long history in treating PTSD; and has been used to treat military veterans and first-responders following 9/11. The investigators are developing and testing a virtual reality platform to be used in treating healthcare workers and COVID-19 patients who develop PTSD resulting from their experiences in the COVID-19 pandemic. Participants will complete ten ninety minute sessions, twice a week for five weeks aimed at mitigating their symptoms of PTSD. The pilot study will aim to demonstrate the feasibility and the tolerability of the virtual reality intervention in these populations.
This study aims to enroll patients with acute infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) who do not meet criteria for hospital admission according to protocols developed by the Honduras Ministry of Health (MOH). Patients who are triaged to home must also be over the age of 60 years or have one high risk comorbidity and be over 45 years in order to meet inclusion criteria. These patients will be randomly assigned to one of four home-based care strategies, which may or may not include regular blood oxygenation monitoring and provision of alcohol-based hand-rub. Patients will be followed until resolution of their acute illness, and data will be collected on feasibility, impact and acceptance of the intervention. Some patients will be followed for up to one year to monitor for post-Coronavirus Disease 2019 (COVID-19) symptoms.
This is a prospective intervention study to assess the effectiveness of both the live attenuated and messenger RNA vaccines against SARS-CoV-2 infection
The study investigates the role of positive pressure, inspired oxygen fraction and different decubiti (seated, supine, prone) on breathing effort (as assessed by esophageal pressure swings) in Covid-19 pneumonia (at different disease stages) and in other causes of respiratory failure. The hypothesis is that positive pressure might be deleterious in terms of breathing effort if the main pathological mechanism associated with Sars-CoV-2 infection in the lung is not alveolar damage (as in other causes of respiratory failure) but vascular impairment as previously reported. The effects of high inspired oxygen fractions and decubiti might also be different with respect to other causes of respiratory failure.
Introduction: Coronavirus Disease 2019 (COVID-19) has caused a global pandemic. Epidemiological and clinical inter-individual differences, symptomatology, recovery and humoral response against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) are key factors to better understand and predict the course of the pandemic. As Health Care Workers (HCWs) are caring for infected patients they are more susceptible to infection, which not only is critical for their own health but also because it results in a shortage of HCWs that seriously affects health services. Thus, maintaining the health and welfare of HCWs and enabling their rapid return to work is vital to overcome this crisis. The ProHEpiC-19 cohort presents data on the immune response of HCWs infected with SARS-CoV-2. This dynamic cohort was started in March 2020 and still continues including participants.
This is a prospective, multicentric, non comparative study aiming to evaluate the clinical and virological evolution of high-risk patients infected with SARS-CoV-2 treated withtin the framework of a cohort ATU ('Autorisation temporaire d'utilisation') or authorisation for early access (AAP) delivered by the French drug agency (ANSM).
The proposed study is a phase 1 study which will evaluate the safety, reactogenicity and immunogenicity of two doses regimen of CoVepiT vaccine (OSE-13E) in the population of n=48 healthy volunteers 18 to 45 (inclusive) years old, vaccinated or not by authorized COVID-19 vaccine. Study will be open label and will be randomized 1:1 in two parallel study arms receiving either one single dose or two doses separated by 21 days. First 4 subjects will serve as sentinel cohort and 7 days reactogenicity data of these subjects will be reviewed by the independent safety monitoring committee (SMC) before proceeding to the vaccination of remaining volunteers. The progress of the study will be overviewed by a safety monitoring committee (SMC). The CoVepiT vaccine is a peptide-based vaccine aiming to induce CD8+T-cell-mediated immune response against 11 different proteins of SARS-CoV-2 virus.
Weeks and months after they have seemingly recovered from COVID-19, many patients continue to suffer from major long-term effects. While the virus typically hits the respiratory system, accumulating evidence now indicates a variety of other, non-respiratory symptoms, some of which manifest long after recovery from the acute phase of the disease. Neurologically-related symptoms among COVID-19 convalescents include extreme fatigue, headaches, sleep and mood disorders, cognitive decline and long-lasting impairments in the gustatory and olfactory systems. Interestingly, it seems that there is no direct link between the severity of the disease in its acute stage and the existence or the severity of the long-lasting symptoms. This means that to date, the possibility that even patients who present mild to moderate symptoms will still go on to develop long-lasting neuropsychiatric disorders following the disease cannot be ruled out. Unfortunately, most of the scientific literature relies on self-report of recovered patients and on qualitative assessments of healthcare workers. The literature still lacks a quantified objective characterization of these long-term impairments. Such data ought to be collected using designated questionnaires and validated neuropsychological assessments. In order to allow for a better understanding of the biological mechanisms that underlie long-term effects of COVID-19, comprehensive research in this population is required. Alongside the identification of the variety of symptoms involved, the importance of an interdisciplinary approach that will take into account the emotional and cognitive aspects of the patients is necessary. Patients need accurate information about the possible consequences of this disease, in order to reduce their anxiety and, if needed, to allow them and their family members and caretakers to prepare for the comings. A systematic characterization of the mental effects of COVID-19 will allow global healthcare systems to develop prevention and rehabilitation programs and provide psychological and/or psychiatric follow-up and intervention programs, according to circumstances. By elucidating the mechanisms underlying emotional and cognitive deficits in COVID-19 convalescents, this study may improve future management of the consequences of the pandemic, potentially contributing to the development of efficient medical treatments for populations who suffer from the long-term effects of the disease.
The objective of this research is to build a collection of non-invasive retinal imaging (OCT and OCTA) in order to investigate the incidence and impact of retinal damage in patients who have or have had COVID-19.
