COVID-19 Clinical Trials and Expanded Access

Prospective observational study aimed at analyzing the incidence, clinical characteristics and outcomes of COVID-19 in LT in Spain.

Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.

The initial symptoms described in the first cases of COVID-19 were mainly fever and respiratory signs. Recently, there has been an increase in cases of hyposmia without associated nasal obstruction or rhinorrhea. Although we do not yet know the long-term consequences of COVID-19 on olfaction, there is evidence in the literature demonstrating that post-viral hyposmias are an important source of long-term olfactory disorders, impacting quality of life. Usually, the treatment of viral hyposmias is based on local and/or general corticosteroid treatment combined with saline nasal irrigation at the onset of signs. Because of the possible development of severe forms of the SARS-Cov-2 infection, the French Society of Otorhinolaryngology has advised against treatment by corticosteroid therapy and nasal irrigation. However, as the virus is present in the nasal fossae on average for 20 days, persistent hyposmia at 30 days would probably result from an inflammatory or neurological damage to the nasal slits or olfactory bulb. Local treatment with corticosteroids could then be instituted from 30 days after the onset of symptoms of COVID-19 without risk of dissemination. In persistent hyposmia other than chronic rhinosinusitis, the only treatment that has proven its efficacy is nasal irrigation associated with budesonide and olfactory rehabilitation. However, this drug does not have marketing authorisation in France for this indication.

The aims of the present study are: 1. To explore the impact of COVID-19 pandemic on the smoking behavior of youth smokers 2. To explore the impact of COVID-19 pandemic on the Youth Quitline service in Hong Kong

A continuous infusion of Dexmedetomidine (DEX) will be administered to 80 patients admitted to Critical Care because of signs of Respiratory Insufficiency requiring non-invasive ventilation. Measurements of respiratory performance and quantification of cellular and molecular inflammatory mediators. The primary outcome will be the avoidance of mechanical ventilation with secondary outcomes duration of mechanical ventilation, avoidance of delirium after sedation and association of mediators of inflammation to outcomes. Outcomes will be compared to a matched historical control (no DEX) series

We plan to perform an observational study to evaluate the prevalence of burnout, depression and medical errors in a designated exclusive Covid-19 patients hospital in Malaysia, during the Covid-19 pandemic. We also seek to assess the relationship between burnout and depression with medical errors. The population studied will be the anaesthesiology fraternity, who are at higher risk to the nature of their work at the frontlines of the pandemic.

Delirium and acute neurocognitive impairment are increasingly observed in adult and pediatric patients with COVID-19. Prospective clinical studies combining clinical and laboratory examinations including specific biomarkers of neuroaxonal injury were not performed for COVID-19. The value of biomarkers of neuroaxonal injury was proven in preliminary studies. These biomarkers could thus contribute to the systematic detection of neurocognitive impairment in patients with COVID-19. Due to worldwide increasing numbers of hospitalized patients with COVID-19, biomarkers of neuroaxonal injury are highly valuable to detect and monitor cognitive impairment, especially with regard to limited resources available to perform time-consuming brain imaging. Biomarkers of neuroaxonal injury are therefore not only of great interest to detect neurocognitive impairment but also to quantify the severity of brain injury in patients with COVID-19.

Coronavirus disease was first diagnosed in December 2019, in the city of Wuhan, China. The World Health Organization recently declared coronavirus disease 2019 (COVID-19) as a pandemic. The infection is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is a single-stranded RNA virus, which in humans causes mild respiratory symptoms and generally has a good prognosis. However, in a certain group of patients it manifests as severe pneumonia, respiratory distress syndrome, multiple organ dysfunction and death. The factors associated with a worse prognosis are older than 60 years, the presence of diabetes, cardiovascular disease and obesity. According to studies carried out in the Eastern world, the prevalence of liver injury in patients with COVID-19 disease varies between 14% and 53%, being more prevalent in patients with severe symptoms of COVID-19 disease. It is not really known whether the liver involvement of patients with SARS-CoV-2 infection is secondary to the direct effect of the virus on the liver. One of the mechanisms of action of SARS-CoV-2 is through the binding to the angiotensin-converting enzyme receptor, which is present in cholangiocytes, this could explain its excretion in faeces. However, liver injury could be due to the immune response generated in the body by the virus with systemic inflammatory response syndrome and the release of inflammatory cytokines such as IL6, generating direct cytopathic damage to the liver. On the other hand, it could be the product of hepatotoxic drugs administered during hospitalization, such as antibiotics, antivirals or non-steroidal anti-inflammatory drugs. Liver biopsy described microvacuolar steatosis, and a mild portal and lobular inflammatory infiltrate . Therefore, the aim this study is to assess the prevalence of liver complications (liver injury, decompensation of cirrhosis) in patients diagnosed with COVID-19 in Latin America. As secondary objectives, the investigators will describe the clinical characteristics of COVID-19 disease and identify risk factors associated with poor prognosis,

The study aims to determine the impact of COVID-19 pandemic lockdown on cardiovascular prevention behaviour.

Following the announcement of the containment of the population due to the COVID-19 epidemic on March 17, 2020 in France, a notable decrease in the number of consultations in general practice was reported. Patients no longer contact their general practitioner, including those with regular follow-up for one or more chronic conditions. This observation raised worries since it could lead to delay or failure in detecting decompensations / complications of these chronic conditions by a lack of recourse to care. Thus, an urgent message from the National Health Department (Direction Générale de la Santé - DGS) was adressed on April 8, 2020 to the health professionals regarding the organization of care aside from COVID-19. The main recommendation was "that the personal physician or the corresponding specialist should contact the most fragile patients with chronic condition to ensure follow-up and detect any risk of decompensation ". Such fragile patients are in great numbers, up to more than 200 for an average general practitioner. Therefore, although this recommendation is regarded as "essential in view of the health needs of the population", it will prove quite difficult to follow without the help of a skilled external assistance that can be quickly mobilized.
