Filter by:A nasal spray based on Advanced Water S-100 ionized water would clean the nasal cavity, reduce the viscosity of the mucus and facilitate its elimination and the decongestion of the nose and the prevention of the seizure of the SARS-COV-2 to the epithelial cells of the nasal cavity In fact, a nasal spray based on Advanced Water S-100 ionized water would modify the electrostatic environment of all interactions ensuring this seizure. The negative ions (OH-) contained in Advanced Water S-100 compete with the negative ions of the heparan sulfate, which will destabilize this essential bond for the virus to enter the host cell. In addition, positively charged basic amino acids, in the presence of the basic pH of ADW S-100, will be neutralized by OH- ions which will prevent the formation of salt and hydrogen bridges mediating the formation of the protein S/ACE2 complex. The destabilization of all bonds governing the protein S/ACE2 association process will prevent the virus from entering cells and replicating. The aim of this study is to evaluate whether the use of ADW S-100 ionized water nasal spray reduces the salivary and nasopharyngeal viral load during an 8-day follow-up of persons recently infected with SARS-Cov-2, and thus potentially decreases the risk of contamination of the entourage.
The aim of this study is to examine the relationship between the severity of fibrosis in the lung tissue and EGFR positivity in patients who died due to covid-19 pneumonia, with the demographic characteristics, comorbidities, biochemistry values, treatments they received, and radiological appearances. Transthoracic tru-cut biopsy will be performed on patients who have died in the intensive care unit with the diagnosis of Covid 19 pneumonia. EGFR positivity will be evaluated in the material taken. The relationship between the severity of fibrosis and the demographic data of the patients, the drugs used and their radiological appearances will be analyzed statistically.
Identify the relationship of obstructive sleep apnea (OSA) prevalence with post-COVID-19 fatigue that remains at least six months after acute disease
A preliminary open-label case report demonstrated the beneficial effects of an innovative nitrate-based nutritional formula on oxygen saturation in patients with COVID-19. Whether these initial findings are relevant in a more robust research design currently remains unknown. Therefore, the main objective of this randomized controlled trial was to analyze the acute effects of nitrate-based nutritional formula on peripheral SpO2, patient-reported outcomes, and safety indices in patients with acute COVID-19 infection.
Experimental, single-arm study in participants with comorbidities, previously immunized with 2 doses of CoronaVac, who will receive a booster vaccine with 1 dose of the Oxford/AstraZeneca vaccine.
International observational studies confirm the high incidence of post-infectious residual syndrome after infection with severe acute respiratory syndrome corona virus 2 (SARS-COV2), which can occur in 10-15% of all infected persons, regardless of the severity of the acute infection. Post corona virus disease 19 (postCOVID-19) patients suffer mostly from symptoms such as fatigue, muscle pain, problems to focus, depression and sleep disturbances. So far, there are no results of interventional studies for the treatment of chronic fatigue post COVID-19, but there are indicators that post COVID-19 syndrome is a chronic subclinical inflammation, similar to Chronic Fatigue Syndrome / Myalgic Encephalomyelitis CSF/ME, which also often develops from a postviral syndrome. Previously tested and effective strategies for the treatment of chronic fatigue syndrome / myalgic encephalomyelitis (CFS/ME) will be tested in the treatment of chronic fatigue postCOVID-19, in this randomized controlled trial a combination of acupressure and Qigong. The aim of this project is to evaluate an acupressure treatment plus a Qigong exercise series specifically tailored for chronic fatigue postCOVID-19 , used daily by the patients themselves and regularly supervised, in comparison to the advice literature on the treatment of PostCOVID-19 syndrome alone.
Since the beginning of COVID-19 pandemic situation, several modes of ventilation have been tried to correct the hypoxaemia induced by SARS-CoV-2 virus. A few recent studies have concluded that high-flow nasal oxygen therapy (OptiFlow™) is beneficial in COVID-19. All mainly conclude that the use of OptiFlow™ avoid intubations and decrease hospitalization duration in critical care services. At the emergency medical service 83 (SAMU 83), it has been decided to extend this ventilation mode during patient secondary transfers (transfer from an intensive care unit/other hospital unit/emergency department to another hospital's intensive care unit). The emergency medical service 83 has equipped its intensive-care ambulances with OptiFlow™ in order not to interrupt this ventilation mode during transport. The hypothesis is that patients with a severe respiratory form of COVID-19 transported from one health facility to another by the emergency medical service 83 on high-flow nasal oxygen therapy has a reduced risk of intubation compared to the other modes of non-invasive ventilation (NIV) and High Concentration oxygen Masks (HCM).
COVID-19 is an infectious disease which presents a heterogenous clinical presentation. Recent investigations suggest that people who were infected by COVID-19 often develop physical disabilities (i.e. pain, fatigue) and neurological complications after hospital discharge. Many therapeutic approaches such as transcranial direct current stimulation (tDCS) have been proposed to minimize functional and structural impairments. Electroencephalogram (EEG) has been used in this population to assess electrophysiological changes in the brain. However, evidences about EEG utilization as efficacy predictor of tDCS in COVID-19 people rest inconclusive.Our objective is to evaluate EEG as neurobiological predictor marker of tDCS efficacy on fatigue, pain, quality of life, self-efficacy and functional capacity in the chronic phase of COVID-19.
COVID-19 is an infectious disease which presents a heterogenous clinical presentation. Recent investigations suggest that people who were infected by COVID-19 often develop physical disabilities (i.e. pain, fatigue) and neurological complications after hospital discharge. Many therapeutic approaches such as transcranial direct current stimulation high definition (HD-tDCS) have been proposed to minimize functional and structural impairments. Recently, I electroencephalogram (EEG) has been used as predictor of HD-tDCS effectiveness in diverse neurological populations. However, evidences about this tool utilization as efficacy predictor of tDCS in COVID-19 people rest inconclusive. Thereby, our objective is to evaluate HD-tDCS efficacy on fatigue, pain and functional capacity of patients with COVID-19 chronic.
This phase 2 clinical trial will evaluate the safety and immunogenicity of additional doses of prototype and variant (alone or in combination) vaccine candidates in previously vaccinated participants with or without prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and will evaluate innate, cellular, and humoral immune responses to inform on how to shift the immune response to cover new variants as they emerge. A randomized open-label, non-placebo controlled, multi-site, multi-stage clinical trial in individuals, 18 years of age and older, who are in a stable state of health, has received a complete authorized/approved vaccine series (primary series + booster either with homologous or heterologous vaccine products) >/ = 16 weeks prior to enrollment. Subjects will be stratified by i) age (18-64 years and = 65 years of age) (however arms 16 and 17 or stage 4 will only enroll participants between the ages of 18-49 years) and ii) history of confirmed prior SARS-CoV-2 infection, and randomly assigned to receive one of several variant vaccines. Enrollment will target a goal of approximately 45% of each of the variant vaccine arms to be in older adults (= 65 years of age) for stages 1, 2 and 3 and approximately 20% to have had confirmed COVID-19 for all 4 stages. The primary objective is to evaluate humoral immune responses of candidate SARS-CoV-2 variant vaccines, alone or in combination.
