Filter by:The purpose of the study is to evaluate the safety and tolerability of a 30-week aerobic exercise therapy program in cancer patients recovering from COVID-19. The study will look at whether the aerobic exercise therapy causes few or mild side effects in participants. Aerobic exercise is physical activity that uses the large muscle groups (muscles in your legs, buttocks, back, and chest) and can be performed for several minutes at a time. The aerobic exercise therapy being used in this study will be a walking program that will be adjusted so it matches participant fitness levels (how much exercise you can handle).
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most frequent complications of the COVID-19 pandemic. In these conditions, hypoxemia may result from : i) a pulmonary vascular dilatation resulting from an impaired hypoxic pulmonary vasoconstriction and leading to ventilation-perfusion mismatching within the lungs and ii) thrombosis-mediated perfusion defects. Pulmonary vascular dilation might be due to a relative failure of the physiological acute hypoxic pulmonary vasoconstriction, in the context of an over-activation of a regional vasodilatation cascade, as part of a dysfunctional inflammatory process. Perfusion abnormalities associated with pulmonary vascular dilation are suggestive of intrapulmonary shunting toward areas where gas exchange is impaired, ultimately leading to a worsening ventilation-perfusion mismatch, a regional hypoxia and a profound hypoxemia. Increased plasma levels of VEGF have been reported in moderate to severe COVID-19 pneumonia, highlighting the role of VEGF in the pathophysiology of the disease. A better prognosis has been reported in critically ill patients with lower levels of growth factors, HGF and VEGF-A at the time of ICU admission. Recent data of the study NCT 04275414 by Pang J et al have suggested that patients receiving a single-dose of bevacizumab have improved their oxygen support status in 92% of cases during a 28-day follow-up period, as compared with 62% of cases in an external cohort receiving standard care. Correcting endothelial permeability and vasodilatation with VEGF-targeted therapy could allow repair damaged vascular endothelium, have an indirect anti-inflammatory effect (limiting alveolar exudation of circulating inflammatory and procoagulant mediators) and improve oxygenation and therefore reduce the proportion of patients with severe forms requiring ICU referral and finally patient death. This clinical trial will therefore focus on the specific efficacy of bevacizumab in COVID-19 patients with severe hypoxemia.
The investigators' aim is to conduct a study looking into safety and feasibility study of Covid patients participating in a self-guided exercises program while admitted to the hospital. The investigators will test 2 forms of exercise instruction, one using an exercise phone-based application, and the other a printed exercise manual.
Microcirculatory dysfunction appears to play a key role in the development of organ failure leading to the death of patients with coronavirus disease 2019 (Covid-19). It is still uncertain today whether this damage is secondary to direct viral infection of endothelial cells or the consequence of the inappropriate inflammatory response induced by the infection. The analysis of endothelial and microcirculatory dysfunctions and glycocalyx degradation therefore appears to be necessary in the understanding of the pathophysiological mechanisms of Covid sepsis and could play a role in the evaluation of the efficacy of certain therapeutics which would aim at improving regional perfusion by decreasing microcirculatory dysfunction.However, the analysis of microcirculatory failure, endothelial dysfunction and glycocalyx degradation has so far only been evaluated in small cohorts, without quantitative analysis of microcirculatory perfusion
The purpose of this study to evaluate the translational application of the safe and effective treatment of Narrow-Band Ultraviolet light B-band (NB-UVB) to high-risk COVID-19 patients in an effort to improve their immune and hemostatic imbalance to increase survival and improve outcomes.
Ice swimming is an increasingly common phenomenon in Poland. It has been confirmed that it has a beneficial effect on health by increasing the natural non-specific immunity to infections. In the face of the current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic causing Coronavirus Disease 2019 (COVID-19), researchers decided to use a survey to check the incidence of COVID-19 among Polish ice swimmers, as well as recent ailments. Then, the researchers will compare the obtained results with epidemiological data for Poland.Researchers will also investigate the relationship between susceptibility to SARS-CoV-2 infection and the blood group and Rh factor among ice swimmers.
Open label, dose escalation study to investigate: 1. Safety, tolerability and immunogenicity of one or two doses of intranasal ChAdOx1 nCOV-19, in vaccine naïve individuals, with randomisation between one and two dose groups. 2. Safety, tolerability and immunogenicity of intranasal ChAdOx1 nCOV-19, given as a booster dose in individuals who have had two intramuscular COVID-19 vaccinations.
Sedation of severe COVID-19 disease are often complicated. We try to find a correlate for this observation by encephalographic studies.
Although several therapeutic agents have been suggested for the treatment of the disease caused by the Coronavirus of the year 2019 (COVID-19), no antiviral has yet demonstrated consistent efficacy. This is an observational study comparing Tenofovir-DF (disoproxil fumarate) (TDF) with Hydroxychloroquine (HCQ) in the treatment of hospitalized patients with COVID-19 with evidence of pulmonary compromise and with supplemental oxygen required.
A preparation of CimertrA, comprising Artemisinin, Curcumin, and Boswellia, and Vitamin C in a nanoparticular formulation, is proposed as a treatment for the disease associated with the novel coronavirus SARS-CoV-2. This initiative is presented under the urgent circumstances of the fulminant pandemic caused by this lethal disease, which is known as COVID-19 and has spread across the globe causing death and disrupting the normal function of modern society. The grounds for the proposal are rooted in existing knowledge on the components and pharmacological features of this formulation and their relevance to the current understanding of the disease process being addressed. The severe acute respiratory syndrome-associated coronavirus disease 2019 (COVID-19) illness results from the immediate response to the viral infection as well as from a subsequent host inflammatory response. Systemic proinflammatory cytokines and biomarkers are elevated as the disease progresses towards its advanced stages, and correlate with worse chances of survival. Serum cytokine levels that are elevated in patients with Covid-19-associated cytokine storm include interleukin-1β, interleukin-6, IP-10, TNF, interferon-γ, macrophage inflammatory protein (MIP) 1α and 1β, and VEGF. Higher interleukin-6 levels are strongly associated with shorter survival. The relative frequencies of circulating activated CD4+ and CD8+ T cells and plasmablasts are increased in Covid-19. In addition to the elevated systemic cytokine levels and activated immune cells, several clinical and laboratory abnormalities, such as elevated CRP and d-dimer levels, hypoalbuminemia, renal dysfunction, and effusions, are also observed in Covid-19. Laboratory test results reflecting hyper inflammation and tissue damage were found to predict worsening outcomes in Covid-19. CimetrA, comprising Artemisinin, Curcumin, Boswellia, and Vitamin C in a nanoparticular formulation, has been studied on patients with COVID-19 in a randomized double-blind control Phase II study (MGC-006 - under a previous product name - ArtemiC). The study product demonstrated excellent safety and efficacy profiles. Experiments performed in vitro with CimetrA demonstrated the ability to reduce cytokine elevation in response to stimulation of human PBMC preparations. The currently proposed Multi-center multinational-controlled study is designed to include 252 adult patients who suffer from moderate COVID-19 infection. Safety will be assessed through collection and analysis of adverse events, blood and urine laboratory assessments, and vital signs. After the screening visit, the study drug will be administrated twice a day morning and evening (every 12 hours) during (day 1 and day 2) The patients will be randomized in 1:1:1 ratio to study drug (CimetrA) in addition to Standard of Care (Arm 1 (CimetrA-1) or Arm 2 (CimetrA-2)) or Placebo in addition to Standard of Care (Arm 3).
