Viral infections provoke the systemic inflammatory response and cause an imbalance between the procoagulant and anticoagulant homeostatic mechanisms. Multiple pathogenic mechanisms are involved, including endothelial dysfunction, increased von Willebrand factor, Toll receptor activation, and tissue factor pathway activation. D-dimer levels greater than 1000 ng / mL are associated with an 18-fold increased risk of mortality. In this context, many patients may require prophylaxis or antithrombotic treatment with low molecular weight heparins. Currently, there is no validated scheme on the dose and timing of the use of antithrombotic drugs. The study aims to identify the effect of two anticoagulant strategies (prophylactic and therapeutic) on the progression to ventilatory support or death in patients with COVID-19 infection who require hospital care.
There is a considerable variation in the disease behavior in terms of contracting the infection, manifesting none to a range of symptoms and severity of the infection among individuals exposed to or infected with SARS-CoV-2 virus, the causative organism of COVID-19. Although the respiratory system appears to be the primary target of this virus infection, emerging evidences suggests involvement of extra-pulmonary organs including central nervous system. We aim to compare the genetic profile of individuals with vs without COVID-19 after being exposed to infected cases. Additionally, we will assess the cognitive function in covid-19 positive cases with vs. without neurological symptoms at the time of infection and 1-month follow-up using the Montreal Cognitive Assessment (MoCA) questionnaire.
Acute Respiratory Distress Syndrome (ARDS) reflects the hallmark of the critical course of coronavirus (COVID19). The investigators have recently shown that Exhaled Breath Particles (EBP) measured as particle flow rate (PFR) from the airways could be used as a noninvasive real-time early detection method for primary graft dysfunction (which bears a pathophysiological resemblance to ARDS) in lung transplant patients. The investigators have also previously demonstrated the utility of PFR in early detection and monitoring of ARDS in a large animal model. PFR has been shown to be elevated prior to the cytokine storm which classically occurs in ARDS. Early detection of ALI and ARDS is intimately linked to a patient's chance of survival as early treatment consisting of the preparation for intensive care, prone positioning and protective mechanical ventilation can be implemented early in the process. In the present study the investigators aim to use real-time PFR as an early detector for COVID19-induced ARDS. The investigators will also collect EBPs onto a membrane for subsequent molecular analysis. Previous studies have shown that most of those proteins found in bronchoalveolar lavage (BAL) can also be detected in EBPs deposited on membranes. The investigators therefore also aim to be able to diagnose COVID19 by analyzing EBPs using Polymerase Chain Reaction (PCR) with the same specificity as PCR from BAL, with the added benefit of being able to identify protein biomarkers for early detection of ARDS.
In December 2019, a highly infectious disease caused by a novel coronavirus (SARS-CoV-2) emerged in Wuhan, China. On March 11th 2020, the World Health Organization (WHO) declared COVID-19 a pandemic. Facing this critical situation, health care workers on the front line are at risk of developing psychological distress and other mental health symptoms. Physical medicine and rehabilitation (PM&R) physicians works both in specialty outpateint/inpatient clinic and pandemic outpatient/inpatient clinics during the outbreak. Accordingly, PM&R physicians are expected to be mentally affected by COVID-19 pandemic. In this study we aimed to evaluate mental health status of PM&R physicians and related factors during COVID-19 pandemic. This study is a cross-sectional survey which is conducted on an online platform. Demographic data, working conditions of PM&R physicians and factors that may be related to mental health status is questioned in the survey. The Depression, Anxiety and Stress Scale - 21 (DASS-21) is used to measure the emotional states of depression, anxiety and stress.The Insomnia Severity Index (ISI) is used to assess the severity of both nighttime and daytime components of insomnia.
At least 1 in 6 COVID-19 patients admitted to hospital to receive extra oxygen will die of complications. In patients with COVID-19, invasive treatment such as mechanical ventilation (e.g. breathing with a machine) is associated with a 50% increased risk of death. Invasive treatments use a lot of healthcare resources in intensive care units and may lead to further deaths if patients do not have access to care. The investigators aim to improve outcomes for COVID-19 patients by implementing hyperbaric oxygen therapy (HBOT). HBOT allows patients to breathe 100% oxygen in a special chamber at a pressure higher than sea level. It is approved by Health Canada for 14 conditions. HBOT is safe when administered by experienced teams. There are two main causes of death in severe COVID-19 respiratory infections: (i) a decreased diffusion of oxygen from the lungs to the blood and (ii) an increased inflammatory response (also called a "cytokine storm"). HBOT leads to increased oxygen level in blood, has strong anti-inflammatory effects, and may destroy the virus responsible for COVID-19 disease. The initial experience with HBOT and COVID-19 from China, France and the United States is promising in that it prevents further worsening of the condition and need for intensive care. The investigators propose to test the effectiveness of HBOT for COVID-19 patients who are admitted to hospital to receive extra oxygen. Using the most rigorous and innovative research methods, this Canadian-led international study will operate at 5 centers across 3 countries (Canada: Ottawa, Toronto, Edmonton; Switzerland: Geneva; UK: Rugby/London). The investigators anticipate that when treated by HBOT, COVID-19 patients needing extra oxygen to breathe will see significant health improvements as well as a decrease in complications, inflammation in the blood, need for invasive care, death, and cost of care.
This study investigates the well-being and health-related quality of life in cancer patients and survivors during the COVID-19 pandemic. Using questionnaires may help researchers gain an understanding of how experiences during the COVID-19 pandemic (e.g., exposure, risk factors, testing, isolation, seropositivity, hospitalization, loss of family or friends, loss of income), may impact multiple domains of health-related quality of life (physical, emotional and social well-being), and other areas such as COVID-19-specific psychological distress (e.g., fear, anxiety and depressive symptoms), and disruptions to health care, finances, and social interactions.
Nursing homes are ground zero for the COVID-19 pandemic. Nursing homes are ill-equipped for the pandemic; though facilities are required to have infection control staff, only 3% have taken a basic infection control course. Significant research has focused on infection control in the acute care setting. However, little is known about the implementation of practices and effective interventions in long-term care facilities.The investigators propose an intervention utilizing Project ECHO, an evidence-based telehealth model, to connect Penn State University experts with remote nursing home staff and administrators to proactively support evidence-based infection control guideline implementation. Our study seeks to answer the critical research question of how evidence-based infection control guidelines can be implemented effectively in nursing homes
The investigators decided to conduct a longitudinal study that compares the pulmonary tomographic patterns found in patients with viral pneumonia (i.e. influenza H1N1 and SARS-CoV-2) at a regional hospital. The primary aim of this study is to evaluate the association between the radiological CT pattern and the need for invasive mechanical ventilation. A secondary aim is to assess the mortality within the first 28 days of intensive care unit admission.
A randomized clinical trial designed and intended to evaluate the efficacy of Dexamethasone and Methylprednisolone as a treatment for severe Acute Respiratory Distress Syndrome (ARDS) caused by coronavirus disease 19 (COVID-19). Our aim is to find the best option for the treatment and management of ARDS in COVID-19 patients.
