Filter by:The current COVID-19 epidemic has overwhelmed the health systems of many countries in which it has broken out, forcing various governments to institute population containment measures. Residents of medico-social institutions for the elderly are particularly at risk of developing severe forms because they have a large number of factors favoring the progression to a severe form (very advanced age, multiple comorbidities, dependence in activities of dayli life). The specificity and positive predictive value of clinical signs are not very important in this population; which makes the diagnosis even more complicated. One of the strategies to try to protect these residents, in addition to room containment and clinical surveillance, would be to carry out a systematic screening campaign of all residents and all caregivers, then to consider reorganizing the establishments with a sector "COVID +". This was announced by the French Minister of Health Olivier VERAN on 04/06/2020 from the first confirmed case of COVID-19 in an institution. However, asymptomatic subjects may have a "negative" RT-PCR test at one point but which is positive in the following days. And in this interval they would still be contagious. It is therefore not excluded that the implementation of such a screening campaign will not be effective in reducing the number of new cases of COVID-19 in medico-social institutions for the elderly
The coronavirus disease of 2019 (COVID-19) has affected over 2.4 million individuals worldwide and has resulted in >171,000 deaths. Cardiovascular disease (CVD) is an important contributor to death in these patients. Those who develop cardiac injury during infection have a 4-fold increased risk of death. Furthermore, pre-existing CVD or cardiovascular risk factors (e.g. diabetes, hypertension) are associated with worse outcomes. Given the recent emergence of this disease, there is limited understanding of: (i) the risk factors for cardiovascular events, (ii) blood biomarkers for early recognition, and drug targeting, of patients at risk of adverse outcomes, and (iii) the short term subclinical and clinical cardiovascular manifestations in those who survive to discharge.
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has caused pandemic since outbreak in 2020. Patients with HIV may be at higher risk than those without HIV for coronavirus disease 2019 (COVID-19). At present, limited data are available on the safety and immunogenicity of coronavirus vaccine for patients with HIV.
Part 1: Primary Vaccination in Adults Part 1 will evaluate the safety and immunogenicity of the recombinant two component COVID-19 vaccine (CHO cell) (ReCOV for short) in adults aged 18 years and older, when administered as 2 intramuscular doses, 21 days apart. Part 2: Booster Vaccination in Adults Part 2 will evaluate the immunogenicity and safety and of one booster dose of ReCOV in adult participants who have received primary vaccination with 2 doses of an inactivated COVID-19 vaccine (CoronaVac®). COMIRNATY®, an mRNA COVID-19 vaccine will be used as the active control.
This study involves conducting a telephonic or in person survey regarding parental perception and attitudes about vaccinating the respective "technology dependent" child with the COVID 19 vaccination. "Technology dependent" includes tracheostomy dependence, artificial ventilator dependence and non invasive mechanical ventilation dependence. This population is vulnerable since most patients have underlying lung disease, chronic respiratory failure and require respiratory equipment to assist with breathing. "Technology dependent" patients are particularly vulnerable to respiratory infections and are considered high risk for developing severe COVID 19 illness. Despite this population's high risk for morbidity and mortality from respiratory viral infections, the investigator hypothesize that 50% of the parents are still vaccine hesitant.
Vaccines against the coronavirus type 2 causing severe acute respiratory syndrome Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) have been created in a short period of time due to the rapid spread of the virus. These vaccines use different and sometimes innovative technologies, such as the use of ribonucleic acid (RNA), or a non-replicating viral vector. Efficacy ranging from 70-90% in the first weeks after the second injection of these vaccines has been reported, with side effects whose causality remains to be determined.
This study is a multi-center, randomized, double-blind, parallel, placebo-controlled, phase III clinical trial to evaluate efficacy and safety of pyramax in mild to moderate COVID-19 patients.
Elderly people who have multiple health problems are at higher risk of illness from viral respiratory infections, such as influenza (the flu) and COVID-19. This is especially true for residents in long-term care because the usual methods of infection control (handwashing, mask-wearing, and distancing) are difficult to enforce due to the memory problems of many residents and the frequently shared common spaces. It can also be difficult to prevent the spread of viral infections within long-term care because many residents are unable to tell their caregivers when they are feeling ill. Also, some elderly people do not show typical symptoms of infection (like fever), instead they may suddenly become confused or weak. This study will test if a safe form of ultraviolet light (far-UVC) can be effective as an extra method of disinfection (in addition to usual manual cleaning) against airborne and surface viruses that can cause respiratory infections.
To provide more information on safety profile of VAXZEVRIA in Japanese subjects, specific drug use result study in subjects with underling disease at higher risk of worsening COVID-19 is planned as an additional pharmacovigilance plan. The present study aims to collect information on adverse drug reactions or COVID-19 infection after VAXZEVRIA vaccination and to evaluate the safety of this vaccine.
In this study, investigators aim to reveal how the COVID-19 pandemic process affects testicular cancer presentations, tumor stages, the time elapsed between diagnosis and intervention, tumor recurrence and progression, which are oncological outcomes.
