Filter by:An observational (cross-sectional) study in the emergency services of participating hospitals, receiving patients with COVID-19 and influenza, aiming to evaluate the diagnostic performance of the rapid antigen detection test for COVID-19 both in nasal sampling and saliva, in patients attending emergency services in the 2020-2021 winter season, performed on site, compared to the gold standard (RT-qPCR).
Randomized controlled clinical trial on using oral ivermectin in COVID-19 prophylaxis supplying the drug to close contacts of confirmed cases.
In this research, silver nanoparticles (AgNPs) were tested in vitro and shown to have an inhibitory effect on SARS-CoV-2 infection in cultured cells. Subsequently, the investigators assessed the effects of mouthwash and nose rinse with ARGOVIT® silver nanoparticles (AgNPs), in the prevention of SARS-CoV-2 contagion in health workers consider as high-risk group of acquiring the infection in the General Tijuana Hospital, Mexico, a hospital for the exclusive recruitment of patients diagnosed with COVID-19.
How the life style changed multidimensionally with home isolation in the period of COVID-19 is a new research question. Physical and social isolation, home isolation, and quarantine policies applied during epidemic periods such as SARS, MERS, Ebola have been associated with lifestyle changes (Lippi, 2019). Much of the research on the health impact of epidemics and isolation has focused on psychological issues such as stress-related symptoms and disorders and to a lesser extent social support and stress management. In contrast, the epidemic and its associated lifestyle issues during quarantine and isolation, including the impact of dietary changes, restricted physical activity, and increased indoor and screen time, are still not investigated. A limited number of studies have examined lifestyle changes during COVID-19 and previous epidemic periods. However, there is no Turkish survey that comprehensively deals with the lifestyle, the scope of which is expanding, today. The Brief Multidimensional Lifestyle Assessment Scale, which we planned to validate in our study, is a scale developed by Balanzá-Martínez et al to multi-dimensionally evaluate the lifestyle changes that occurred during the COVID-19 outbreak. It consists of 7 parts (Diet and Nutrition, Substance addiction, Physical activity, Stress management, Restorative sleep, Social support and Environmental exposure) and a total of 27 items. There are response options measured using a 4-point Likert scale. High scores indicate a healthy lifestyle (Balanzá-Martínez, 2021). In this context, we think that adapting the Short Multidimensional Lifestyle Assessment Scale / Short Multidimensional Inventory Lifestyle Evaluation - Confinement (SMILE-C) questionnaire into Turkish will make a significant contribution to the literature.
This study is a double-blind, randomized phase Ⅳ clinical trial of the inactivated SARS-CoV-2 vaccine (CoronaVac）manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the lot-to-lot consistency, immunogenicity and safety of CoronaVac in healthy adults aged 26-45 years.
Flow controlled ventilation (FCV) is a fairly new mode of mechanical ventilation, consisting of a constant inspiratory and expiratory flow. Inspiration is thus comparable to volume controlled ventilation (VCV). The actively controlled, constant flow during expiration is unique. FCV is known to minimize dissipated energy to the lung [ref] and is therefore supposed to aid in lung protective ventilation. The VICAR study is designed as a prospective single cohort crossover trial. The intervention consists of a sequence of respiratory modes: baseline pressure controlled ventilation (PCV) during 5 minutes, followed by 30 minutes of FCV with an evone respirator (Ventinova Medical B.V., Eindhoven, The Netherlands) and eventually 30 minutes of VCV. Every participant will receive the intervention. Respiratory rate (RR), positive end-expiratory pressure (PEEP) and inspiratory fraction of oxygen (FiO2) will be held constant. According to the manufacturers guidelines, an I:E ratio of 1:1 will be pursued during FCV. During FCV, the respirator will be set with the same PIP as during baseline PCV. For VCV, the same tidal volume as during baseline PCV will be set.
In April 2020, a meta-analysis on the long-term sequelae of respiratory syndromes related to seasonal coronaviruses (SARS and MERS) showed a significant alteration in quality of life, with in particular a decrease in physical and emotional capacities and a deterioration of social life. An improvement of the quality of life is evidenced after 6 months but without reaching the level usually observed in healthy people. The impact of SARS-CoV-2 infection on quality of life can be explained by the persistence of pleomorphic symptoms in the medium to long term. In the military population, the majority of SARS-CoV-2 cases present minor to moderate forms of the disease. Military personnel have living conditions that differ from those of the general population, in particular because of their geographic mobility, which may be responsible for isolation from the family. This isolation can be regular (we speak of "geographical celibacy" when the soldier is posted in a geographical area far from the family unit) and/or occasional, during missions on the national territory or outside. This singularity justifies a study on the impact of SARS-CoV-2 (COVID-19) infection on the quality of life in this specific population.
Although its safety and efficacy in the COVID-19 patient population are still unclear, tocilizumab is one of treatment. Tocilizumab is a U.S. Food and Drug Administration approved IL-6 receptor antagonist widely used to treat CRS secondary to the chimeric antigen receptor T cell. In this study the investigators will evaluate the efficacy of Tocilizumab, an IL-6 antagonist administered in the early period in intensive care patients with COVID-19 pneumonia followed by hypoxic and systemic inflammation is predominant, but who do not support mechanical ventilation.
This is a randomized, observer-blind, parallel-controlled study, for evaluation of safety and immunogenicity of sequential immunization of a recombinant SARS-CoV-2 vaccine (adenovirus type 5 vector) in Chinese healthy adults aged 18-59 years after the priming vaccination of inactivated vaccine. 300 healthy subjects aged 18-59 years will be recruited in this study. Of them, 200 subjects who have been vaccinated with two dose of inactive SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 3~6 months later. Other 100 subjects who have been vaccinated with one dose of inactivated SARS-CoV-2 vaccine will be recruited and randomized at a 1:1 ratio to receive a booster dose of inactivated SARS-CoV-2 vaccine or recombinant SARS-CoV-2 Ad5 vectored vaccine at 1~3 months later. The occurrence of adverse events within 28 days and serious adverse events within 6 months after vaccination will be observed. In addition, blood samples will be collected on day 0 before the boosting with ad5 vectored vaccine and on day 14, 28 and month 6 after the boosting. Serum antibody levels, cellular immune responses and the subgroups or germlines of the specific B cells will be analyzed. Each subject will remain in this study for approximately 6 months.
The purpose of this clinical trial is to assess the safety and efficacy of Clevudine 150 mg versus placebo once daily administration with standard of care therapy for 10 days in patients with mild and moderate COVID-19.
