Filter by:This study is a 12-month, four-arm parallel-group randomized control trial of Pfizer-BioNTech versus MODERNA COVID-19 (Corona Virus disease 2019)vaccine boosters in chronic kidney disease and dialysis patients with poor humoral response following COVID-19 vaccination, in collaboration with 5 dialysis centers in Ontario and British Columbia, Canada . Patients will be randomized to MODERNA or Pfizer-BioNTech COVID-19 vaccine, they may have received either MODERNA or Pfizer-BioNTech COVID-19 vaccine for their initial two doses of vaccine, and will be stratified by their initial vaccine type (MODERNA or Pfizer-BioNTech ) prior to randomization, which will result in four study groups.
The primary aim of this study is to evaluate the efficacy and safety of AT1001 versus placebo in pediatric patients with SARS-CoV-2 infection who experience early signs of MIS-C and are at high risk of progression. AT1001 10 μg/kg/dose up to 500 μg/dose (rounded to the nearest 50 μg) or matching placebo will be administered orally four times a day (QID) to the standard of care for MIS-C.
The aim of the clinical study is to study the safety, reactogenicity and immunogenicity indicators of the EpiVacCorona vaccine, with the involvement of volunteers aged 60 years and above. The research tasks are to: - to evaluate the safety of the EpiVacCorona vaccine when administered twice intramuscularly, with the participation of volunteers aged 60 years and older; - to evaluate the reactogenicity of the EpiVacCorona vaccine when administered twice intramuscularly, with the participation of volunteers aged 60 years and older; - to identify any adverse effects to the administration of the vaccine; - to study the humoral and cellular immune responses response following two doses of the EpiVacCorona vaccine, with the participation of volunteers aged 60 and older.
A retrospective, single centre observational study to validate use of the HACOR score (Duan et al, 2017) in determining efficacy of non-invasive ventilation in Covid-19 respiratory failure.
This retrospective study will evaluate characteristics, vaccine utilization and outcomes among subjects with immunocompromising conditions that received COVID-19 vaccination.
In March 2020, the World Health Organization (WHO) declared the novel coronavirus (COVID-19) a global pandemic. Ontario has confirmed more than 547,000 cases of COVID-19 since testing began. For many of these patients, symptoms resolve within 4 weeks of onset. However, it is becoming apparent that a significant number of individuals are experiencing symptoms that persist long after the acute infection, known as Long COVID. These individuals have a wide constellation of presenting symptoms, often varying from initial presentation. For this study, we will be enrolling individuals receiving care at The Ottawa Hospital for Long COVID. This study aims to determine the following four things: 1) will adding electronic case management improve quality of life three months after coming to hospital with Long COVID; 2) is the electronic case management platform cost effective; 3) is there any factors that predict outcomes at 3 months; 4) to determine how a personalized rehabilitation program supported by a digital platform could be implemented for individuals with Long COVID. We will enroll individuals from The Ottawa Hospital who will then be randomly assigned to receive either usual care or usual care plus electronic case management, through a platform called NexJ Connected Wellness. Participants will also complete questionnaires every 4 weeks for 3 months. We will be looking at quality of life, mental and physical health, cognitive symptoms, fatigue and pain.
Viruses are a major health problem for the general public and at risk populations. Normally, detection of antibody titers is the gold standard for determining the effectiveness of the immune system following natural or vaccine caused immunization. However, determining the effectiveness of other parts of the immune system are less common due to the difficulties with testing. Furthermore, there is a critical need to address other therapies in case vaccination is not successful in immuncompromised populations. Exercise has been shown to increase the strength of the immune system against many types of viruses and therefore could be simple way to improve immunity against the COVID-19 virus. The aim of this research is to determine the effects of exercise on anti-viral immunity against many types of common viruses before and after vaccination. We hypothesize that exercise will enhance the anti-viral immunity before and after vaccination. Up to 30 healthy volunteers (age 18-44 years) will be recruited to participate in this study. For completion of Aim 1, three visits are needed totaling around 7 hours of the patient's time and for Aim 2, three visits are needed totaling around 4.5 hours of the patient's time. The initial visit will be for pre-screening and if deemed healthy enough to participate, an exercise test to determine the VO2 max of the participant will be conducted. The following visits will require a trained phlebotomist to insert an in-dwelling catheter and participants will undergo a 20-minute incremental exercise trial. Approximately 50mL of blood will be collected at four different timepoints: at rest, 60% VO2 max, 80% VO2 max, and 1-hr post-exercise. All four collected blood samples will be used to expand viral specific T-cells and compare IFN-γ rele
The purpose of this study is to examine the effect of Andrographis Extract, Boesenbergia Extract compared to standard treatment in asymptomatic COVID patients.
Hypoxemic acute respiratory failure is one of the main COVID-19 patients complication that lead to in intensive care hospitalization. This complication determines a variable mortality from 25 to 30%. To correct hypoxemia (often severe) is often needed non-invasive or invasive mechanical ventilation. Mechanical ventilation is not a therapeutic strategy, but it allows to extend the time-to-recovery necessary to solve COVID-19 respiratory failure cause. Calibration of ventilatory support is essential to ensure adequate time-to-recovery without contributing to onset lung and / or diaphragmatic damage. Basal diaphragmatic activity assessment, device for administering the oxygenation support choice and setting ventilatory support parameters are decisive. Ultrasound is the best method for measuring diaphragmatic work. The aim of this study is to evaluate the diaphragmatic thickening fraction in COVID-19 patients admitted to Intensive Care Unit (ICU) for acute respiratory failure and to record its function on weaning.
Long-term neurocognitive and psychiatric consequences of COVID-19 remain mostly unknown to date. It has been reported that coronaviruses cause direct central nervous system infection (Needham et al. 2020). Besides that, new or worsening cognitive impairment commonly occurs and persists in survivors of intensive care unit (ICU) stay (Hosey & Needham. 2020). The purpose of our study is to search and describe the cognitive and psychiatric long-term consequences of COVID-19 on patients who have been discharged from critical care units. This is an ambidirectional cohort study, that attempts to follow adults discharged from critical Care Units Adults due to COVID-19 up to 12 months after discharge, to evaluate the presence of cognitive impairment, linguistic and phonation function, depression, fatigue, functional gastroenterological symptoms, anxiety, or post traumatic disorder, and performance in activities of daily living and physical response to exercise as well.
