Active clinical trials for "COVID-19"

The objective of this study is to evaluate the efficacy and safety of the Unisabana-Herons invasive mechanical ventilator designed to provide the basic ventilatory support necessary to preserve the life of patients with respiratory failure and indication of mechanical ventilation, especially for those who suffer from acute respiratory distress syndrome (ARDS) when conventional commercial invasive ventilators are not available in the context of the health emergency due to the COVID-19 epidemic. The Unisabana-Herons ventilator allows to precisely configure the respiratory rate, tidal volume (or inspired air volume), inspiratory time, the inspiration: expiration ratio, the positive pressure at the end of expiration (PEEP), the inspired fraction of oxygen and inspiratory air flow, parameters that allow managing the respiratory failure associated with COVID-19. The ventilator also monitors peak inspiratory pressures (PIP), mean, PEEP, plateau, and graphs in real time the pressure-time, volume-time, flow-time curves, which allows detecting when one of these is at levels dangerous to induce ventilator trauma (barotrauma and volutrauma) and thus ensure effective and safe ventilation, so as to avoid ventilator-induced lung injury.

The study is a randomized controlled trail with an observational arm and aims at collecting information on the prevalence of COVID 19 infection in seasoned yoga practitioners by comparing it with the prevalence of COVID-19 infection prevalence rates among age and gender matched control participants who do not practice yoga. The study hypothesizes that yoga practice promotes protection and enhances recovery from the COVID-19 infection. To prove the hypothesis, the study investigators are collecting and comparing responses from seasoned yoga practitioners to age and gender matched controls participants (who do not practice yoga routinely) regarding their recovery from the COVID 19 infection. Based on validated questionnaires on perceived stress, anxiety, depression, well-being, mindfulness, joy disposition, and resilience in participants over the study duration, the investigators also collect information on participant's mental and emotional predispositions.

This study intends to find out how a cloth mask may impact exercise capacity, to provide guidance for exercisers to adjust their expectations and training accordingly. The investigators plan to asses exercise capacity through estimated peak oxygen consumption (eVO2peak), oxygen saturation and level of perceived exertion during treadmill based exercise while wearing a cloth mask compared to exercising without a cloth mask. The potential significance of this study is to determine if subjects can exercise safely and if their exercise training needs to be adjusted while following the current recommendations of wearing a cloth mask in public. The degree of airflow limitation experienced will depend on the type and fit of the mask being worn, and inadequeate airflow could possibly result in CO2 re-breathing if all air was not fully discharged from the mask with each breath. This re-breathing of CO2 could potentially limit the workload leading to a detriment in performance, and increase in adverse symptoms such as dizziness, lightheadedness, chest pain or shortness of breath that does not improve with rest.

This exploratory, open-label clinical study aims to explore the physiologic effects of KB109, a novel glycan, on adult patients with COVID-19 illness on gut microbiota structure and function in the outpatient setting.

Background: Some people have allergic reactions to COVID-19 mRNA vaccines. Researchers want to learn more about these reactions to provide guidance on who can safely receive the vaccines, including a second dose in people who had a reaction to the first. Objective: To study the safety of giving a second mRNA COVID-19 vaccine dose to people who had a systemic allergic reaction to their first dose. Eligibility: People aged 16-69 who had a systemic allergic reaction to their first dose of COVID-19 vaccine. Design: Individuals who have underlying health issues may need to come to the NIH for screening tests to make sure they are safe to receive the vaccine. People who are eligible to participate in the study will be admitted to the NIH hospital and stay for at least 4 days. They will give urine samples. They will have a nasal swab SARS-CoV-2 test. They will have an intravenous line placed in each arm. They will get the study vaccine (Pfizer-BioNTech COVID-19 vaccine) and one dose of placebo on different days. They will have breathing tests. They may have clinical photography if they develop a rash. Participants will have 4 follow-up visits - 2 by phone and 2 in-person visits at the NIH campus . They will have allergy skin testing at one visit. Drops of different allergens or controls will be placed on their back or arm. The skin under each drop will be scratched with a tool. If the results are negative, a small amount of allergen will be injected just below the surface of their skin. Participants who have no or only a mild allergic reaction to the second dose of the vaccine may be eligible to receive a Booster dose at the NIH. Participation will last for approximately 5 months.

The acute pneumonia pandemic caused by a new strain of corona virus 2019 named as COVID-19 by the World Health Organization (WHO) is a pandemic caused by SARS-CoV-2 virus. The reported symptoms vary from fever or chills, cough, shortness of breath, to muscle aches, headaches, loss of taste or smell. The hard capsule KOVIR is a product based on the traditional medicine named "Nhân sâm bài độc táng" which is used to treat the cold conditions, also known as the initial plague according to the theory of traditional medicine.

The study was conducted experimentally to evaluate the effect of neurolinguistic programming on COVID-19 fear in kidney transplant patients.

The purpose of this study is comparing vital signs between standard care and prone position groups. Standard care will consist of routine clinical care, including any advice to lie in prone position as routinely recommended by participating sites. For those randomized to prone position, a special intervention team will visit patients' rooms aiming for patients to maintain the prone position for at least 8 hours a day.

The virological diagnosis of SARS-CoV-2 infection is pivotal for the control of the outbreak by large screening of a- or pauci-symptomatic subjects. Despite nasopharyngeal swabbing tested by RT-PCR is considered as the gold standard, new strategies based on self-samples are considered as valuable alternatives because of their non-invasiveness and ability to be performed in the absence healthcare worker, especially when the subject is asymptomatic and needs to be tested repetitively. The aim of the present project is to evaluate two strategies both based on self-samples: (i) a saliva sample combined to an anterior nare self-swabbing tested by antigenic test versus (ii) a saliva sample tested by RT-PCR. The comparison will be performed during a mass screening of the population of the city of Saint-Etienne (170000 inhabitants), France. The sensitivity of the rapid antigenic test will be evaluated in comparison to that of RT-PCR considered as gold standard.

Two randomized controlled trials will be conducted to examine the effect of a food supplement on proinflammatory cytokines and biomarkers in an adult population recently diagnosed with COVID-19 who are asymptomatic or experiencing only mild symptoms. The supplement, palmitoylethanolamide (PEA), is marketed under the trademarked product with increased bioavailability and format versatility: Levagen+™ (Gencor Pacific Limited, Irvine, CA). The supplement curcumin is marketed under the trademarked product with increased bioavailability: HydroCurc (Gencor Pacific Limited, Irvine, CA)
