COVID-19 Clinical Trials and Expanded Access

The purpose of this pilot study is to measure the impact of non-invasive pneumatic manipulation of transthoracic pressure on oxygenation in patients with Acute Respiratory Distress Syndrome (ARDS) due to Coronavirus Disease 2019 (COVID 19) who are on mechanical ventilator support. This will be achieved by a pneumatic Vest placed around the chest wall of consenting patients who meet inclusion criteria. The Vest is essentially a non-invasive segmental device placed upon the anterior and posterior right and left aspects of the chest wall. The researchers have the ability to inflate and deflate the chambers of the Vest to achieve preset pressures as determined by the protocol and observe the patient's physiological response. Participants will have up to four hours of intervention with the study intervention, followed by 1 hour of post-intervention observation.

This study will examine the feasibility of conducting an online Randomized Controlled Trial (RCT) in frontline hospital and long term care healthcare staff in managing COVID-19 patients in London, ON. The study will randomize participants to Sudarshan Kriya Yoga (SKY) or a Health Enhancement Program (HEP).

The COVID-19 pandemic has led to a potential shortage of life-saving mechanical ventilators. The purpose of this study is to determine whether a novel simpler to device, the automated bag-valve-mask (BVM) compressor, can be used to provide assisted ventilation temporarily to patients in need. This includes patients with COVID-19 lung infection and respiratory failure. If successful, this would increase the pool of total available ventilator hours to alleviate any shortage.

Coronavirus COVID-19 is an emerging virus also called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Eighty percent of patients are poor or asymptomatic. However, there are major respiratory complications for some patients, requiring intensive care hospitalization and possibly leading to death in 5% of cases. One of the hypotheses put forward is that much of the pathophysiology is due to endothelial dysfunction associated with disseminated intravascular coagulation. The covid-19 pathology could induce coagulation impairment as observed during sepsis. An increase in D-dimer levels during covid-19 disease is itself associated with excess mortality. While D-dimers are highly sensitive, they are not specific for clotting activity. They may be increased in many other circumstances, particularly in inflammation. On the other hand, the infection stimulates the release of extracellular vesicles. These vesicles, of multiple cellular origin, are an actor of vascular homeostasis, and participate in the state of hyperactivation of coagulation. They have a major role in the prothrombotic state and the development of coagulopathy associated with sepsis. The aim of our monocentric prospective study would be to study early and more specific markers of hypercoagulability and markers of routine endothelial dysfunction, as soon as the patient is hospitalized, in order to predict the risk of hospitalization in intensive care.

The infectious disease COVID-19, caused by coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), has been declared a pandemic and an international healthcare emergency by the World Health Organization (WHO). It has spread across the globe, overwhelming healthcare systems by causing high rates of critical illness. Mortality from COVID-19 exceeds 4%, with older people with comorbidities being extremely vulnerable. It is expected that between 50-80% of the world's population may contract SARS-CoV-2 over the next two years. It is expected that the outcomes will be potentially worse in Africa, because firstly, there is a limited workforce, and secondly there are limited intensive care facilities and critical care resources across Africa to provide sufficient care. It is important therefore to establish what resources, comorbidities and interventions are potentially associated with either mortality or survival in patients with COVID-19 who are referred for critical care in Africa. Rapid dissemination of these findings may help mitigate mortality from COVID-19 in critical care patients in Africa. These points provide the rationale for the African COVID-19 Critical Care Outcomes Study (ACCCOS).

The novel coronavirus (SARS-CoV-2) has spread all around the world and testing has posed a challenge globally. Health care providers are highly exposed and are an important group to test. On top of these concerns, health care workers are also stressed by the needs on responders in the COVID-19 crisis. The investigators will look at different ways to measure how common COVID-19 is among health care workers, how common is the presence of antibodies by serological tests (also known as serostatus). The investigators will describe health worker mental and emotional well-being and their coping strategies in their institutional settings. Lastly, the investigators will describe how knowing serostatus can affect individuals' mental and emotional well-being and how to cope in the midst of the COVID-19 response. This will help to how to better test and help healthcare workers in the COVID-19 pandemic and prepare for possible future outbreaks.

This study is a case-control study to characterize the molecular and cellular anomalies of the olfactory epithelium of COVID-19 patients with isolated anosmia, by comparison with the olfactory epithelium of non-infected subjects.

The International Registry of Coronavirus Exposure in Pregnancy (IRCEP) is a prospective cohort study of pregnant and recently pregnant women who have been tested for SARS-CoV-2 (regardless of the result) or have been clinically diagnosed with COVID-19 by a health care professional. Data from the IRCEP will be used to evaluate the impact of COVID-19 on pregnancy and birth outcomes.

Prospective registry for multimodal assessment of neuromuscular pathology associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, enrolling consecutive patients with corona virus disease 2019 (Covid-19), who are admitted to the intensive care unit of the department of anesthesiology and intensive care medicine, or the department of neurology at Tübingen University Hospital.

The administration of Calcifediol in patients with COVID-19, will reduce the development of SARS and the worsening of the various phases of the syndrome. Reducing at least 25% in ICU admission and death from the process, reducing days of hospitalization, facilitating the recovery of the same, acting significantly and positively, in any of its phases throughout the natural history of illness. As a treatment with extensive experience of clinical use, safe, inexpensive, and potentially very effective, it will have a highly efficient cost-benefit impact on the prevention of SARS.
