Filter by:This is a multicenter, randomized, double blind, parallel placebo controlled, phase 3 clinical trial to evaluate the protective efficacy, safety and immunogenicity of inactivated SARS-CoV-2 vaccines in healthy population 18 years old and above.
Сonducting in-depth medical and biological studies of the pathogenesis of the disease caused by the SARS-CoV-2 in Moscow, the Moscow region and some other regions of the Russian Federation.
This is a phase 3, randomized, observer-blinded, placebo-controlled study to evaluate the efficacy, safety, and immunogenicity of SARS-CoV-2 rS with Matrix-M1 adjuvant in adult participants and adolescent participants. Additionally providing a Booster Dose to fully vaccinated participants. A substudy is to be conducted at selected sites to evaluate the safety and immunogenicity of a fourth dose (second booster) of NVX-CoV2373 in adults and adolescents, previously fully vaccinated and subsequently boosted with a third dose (first booster)
The worldwide COVID-19 pandemic has led to a dramatic increase in the number of patients hospitalized in intensive care units for an acute respiratory failure in all countries. This situation has quickly led to massive shortage in masks, mechanical ventilation machines and common medications such as hypnotics. All countries over the world are currently experiencing a major shortage in basic hypnotic medications (propofol, midazolam) in the intensive care as well as in the operating theatre. The Principal Investigator proposes to perform a pilot study assessing the benefit-risk ratio of Remimazolam (a novel benzodiazepine with a short half-life) in the critical care units of Nantes University Hospital during the COVID-19 pandemic.
Since the COVID-19 pandemic began, several psychological support programs for health care workers have been implemented, especially group or individual counseling sessions delivered face-to-face or using phones and video conferencing platforms. However, there are significant barriers to the delivery of such psychological initiatives. In this context, digital interventions to improve health services and care outcomes are recommended for implementing and providing remote psychological support. Virtual reality can play a relevant role in providing psychological care to healthcare workers facing COVID-19. New commercial head-mounted display have made virtual reality accessible even to the mass audience, breaking down the barriers in the diffusion and use of this technology. Thanks to this fact, virtual reality can now be autonomously used by people and offered to provide psychological assistance remotely. Within this context, this randomized controlled study aims to investigate the efficacy of a virtual reality home-based program for diminishing stress and anxiety in a sample of Italian healthcare workers involved in the COVID-19 pandemic.
The main objective of the present study is to determine ICU and in-hospital mortality associated with COVID-19 infection and its independent predictors, in patients admitted to adult ICUs in Argentina with a requirement for mechanical ventilation. Secondary objectives include: determining epidemiological and clinical data in patients with COVID-19 disease; the associated morbidity, the support and therapeutic measures implemented, and the evolution of these patients upon discharge from the ICU. Likewise, characteristics of each ICU will be recorded, and a survey will be carried out on the management of the COVID-19 pandemic, which will require information on the additional availability of critical resources for the care of patients admitted to the ICU. Likewise, characteristics of the ICU and hospitals will be registered.
The propose of this study is implement adjuvant therapy with adipose tissue derived-mesenchymal stem cells (MSCs) for critical COVID-19 patients admitted to the intensive care unit of the Regional Hospital Lic. Adolfo López Mateos of the Institute for Social Security and Services for State Workers to reduce cytokine storm and contribute to the favorable resolution of respiratory insufficiency and multiple organic failure.
(a) Objectives 1. To assess the full lung function, exercise capacity, quality of life in patients with COVID-19 over 2 years. 2. To assess the longevity of the serology response to SARS-CoV2. 3. To investigate the association of the neutralization titer in plasma from different vaccinated cohorts to its protection of infection using in vivo model 4. To investigate the SARS-CoV-2 specific cellular and humoral immunities as well as their determinant factors from community subjects who have received different types of COVID-19 vaccines. 5. To assess the third booster dose for subjects who have poor antibody response despite having received two doses of CoronaVac (Sinovac)
The purpose of this study is to assess the efficacy of Xylitol plus Grapefruit Seed Extract (Xlear) nasal spray as an adjunct treatment of COVID-19.
The investigators propose a prospective, randomized, double-blind, placebo-controlled study, conducted in two phases. The purpose of the study is to evaluate the safety and efficacy of methotrexate in a cholesterol-rich non-protein nanoparticle (MTX -LDE) in adults diagnosed with mild Coronavirus-19(COVID-19) disease. A total of 100 patients will be randomized to receive MTX-LDE or placebo each 7 days, up to 3 times, during in hospital treatment.
