Filter by:An Open Comprative Study of the Prophylactic Efficacy and a Non-comparative Study of the Immunogenicity and Safety of the Inactivated Whole-virion Concentrated Purified Coronavirus Vaccine (CoviVac), Produced by FSBSI "Chumakov Federal Scientific Center for Research and Development of Immune-and-Biological Products", on Volunteers at the Age of 18-60 Years
The health crisis linked to the coronavirus has had a significant impact on the mental health. The question of the repercussion of this crisis on the consumption of psychotropic drugs is crucial. It is all the more true in France, which was already among the countries with the highest consumption of psychotropic drugs before the crisis. Indeed, an increase in the number of reimbursements for anxiolytic, hypnotic and antidepressant drugs has been highlighted in the context of the health crisis, using data from the health insurance database. To enhance the understanding about the impacts of the health crisis on the use of psychotropic drugs, it is essential to characterize the evolution of the use at the individual level. The main objective is to assess the impact of the coronavirus-related health crisis on the consumption of psychotropic drugs by studying the trajectories of reimbursements. The secondary objective of the project is to evaluate the evolution of problematic consumption of psychotropic drugs in the context of the health crisis.
Recent advances have been made in prevention of the viral infection via vaccines but there is still need for effective treatment options for patients. Novel therapies need to be developed to further improve clinical outcomes. The biggest medical challenge in the response to COVID-19 is ARDS requiring hospitalization in an intensive care setting and ventilator dependence. Intravenously administered umbilical cord derived exosomes and stem cells have been reported in literature to alleviate pulmonary distress in such patients. The purpose of this study is to explore the safety and benefits of intravenous administration of WJPure and EVPure in the treatment of COVID-19 patients with moderate to severe ARDS. .
The emergence of a novel coronavirus(SARS-CoV-2) in late 2019 has resulted in a global epidemic of the infectious condition COVID-19. Since March 2022, the Omicron mutant has caused widespread transmission in Shanghai, China, and is characterized by the majority of asymptomatic patients. Although showing no obvious symptoms, the asymptomatic patients have high transmissibility because of high viral loads in their oropharynx and nasopharynx. Thereforeļ¼this study puts forwards the hypothesis that local flushing treatment in the sino-nasal and mouth cavity can reduce the viral load to reduce their transmissibility. Nasal Irrigation and gargling is a safe and commonly used mechanism to treat a variety of sinonasal diseases including sinusitis, rhinitis, and upper respiratory tract infections. Povidone-iodine(PVP-I) is a water-soluble complex of povidone, a carrier molecule, and iodine, which has powerful microbicidal activity. Also, recent evidence of in-vitro virucidal action of povidone-iodine in Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS CoV-2) has been supported. Therefore, the study is designed to assess the virucidal effect of nasal irrigation and gargling with PVP-I against SARS-CoV-2 located in the throat. The hypothesis was that the treatment would be effective in improving the negative conversion rate of SARS-CoV-2 nucleic acid on day 10.
Background: Influenza and coronavirus have been repeatedly causing pandemic recently. Like the Influenza A/H7N9 virus has caused five epidemics in China since its first detection in East China in 2013. In 2017, the previously low pathogenic avian influenza (LPAI) H7N9 virus underwent mutation in its haemagglutinin to give to a highly pathogenic avian influenza (HPAI) virus causing 32 human cases and potentially poses a threat to animal and human health. More recently, the SARS-CoV-2 pandemic has been heavily affecting the world. Therefore an effective risk assessment platform is urgently required for better pandemic preparation. Hypothesis: The tissue tropism and pathogenesis of a newly emerged infectious viruses, like the highlypathogenic influenza, like H7N9 and coronavirus, like SARS-CoV-2 would be different from that of their low pathogenic subtype and it would infect and replicate the human respiratory system more efficiently. Because of its resistance to oseltamivir for influenza and no effective antiviral for coronavirus, investigators therefore propose to set up an novel and effective risk assessment platform for emerging infectious viruses. Experimental Design: The tissue tropism and viral replication kinetics of a HPAI and LP influenza and coronavirus will be determined in ex vivo cultures of human brain and compared with their LP subtype. The replication competence and innate immune responses of influenza and coronavirus will be studied and compared with other LP virus in in vitro cultures of human brain cells and human microvascular endothelial cells (HMVEC) both isolated from human brain tissues. Expected outcomes: HPAI influenza and coronavirus particularly SARS-CoV-2 will infect and replicate the human brain tissues and cells more efficiently than their LP subtype. Besides, HPAI influenza and SARS-CoV-2 will induce dysregulated host innate immune response than the LP subtype.
Aimed to understand if yoga exercises are superior to posture exercises as an alternative exercise therapy for relieving musculoskeletal pain, improving functional status, and improving quality of life during the post- corona virus disease (COVID-19) period?
1. Investigate the possible effects of interleukin-6 receptor antagonists such as tocilizumab and sarilumab on the levels of IL-6, inflammtory and anti-inflammtory markers and cytokines before and after treatment in critically ill corona virus disease-19 patients. 2. Correlate between IL-6 levels with other inflammatory markers as ferritin and C-reactive protein. 3. investigate the possible changes on the levels of other inflammatory, anti-inflammatory markers and cytokines such as IL-10 and IP-10, before and after treatment.
Multicenter double-blind placebo-controlled parallel-group randomized clinical trial of efficacy and safety of Raphamin in the treatment of coronavirus disease 2019 in outpatients.
The AudibleHealth Dx is a diagnostic software as a medical device (Dx SaMD) consisting of an ensemble of software subroutines that interacts with a proprietary database of Signal Data Signatures (SDS), using Artificial Intelligence/Machine Learning (AI/ML) to analyze forced cough vocalization signal data signatures (FCV-SDS) for diagnostic purposes. This study will evaluate the performance of the AudibleHealth Dx in comparison to a standard of care Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) test for the diagnosis of COVID-19. A secondary purpose of the study will be usability testing of the device for participants and providers.
NDV-HXP-S is an inactivated COVID-19 vectored-vaccine virus using the Newcastle Disease Virus as basis and expressing Spike (S) protein from SARS-CoV-2 stabilized in pre-fusion form with Hexapro technology. This vaccine was successfully tested in non-clinical and clinical studies with a good safety profile and eliciting neutralizing antibodies against SARS-CoV-2. Clinical testing is conducted by an international consortium including three different manufacturers. Butantan, in Brazil, is one of them.
