Filter by:Of the 1,900,000 Canadians who have been infected by COVID-19, 8 to 15% will continue to experience COVID-19 related symptoms well after 12 weeks. The persistence of such symptoms is now defined as "long COVID" syndrome. Current evidence does not provide a clear understanding of the physical and cognitive impairments and functional limitations that persons with long COVID present. The objectives of this project are to describe the physical and cognitive impairments and functional limitations experienced by people with long COVID and compare the evolution over 6 months of people from three separate groups: a group of people with long COVID (long COVID Group), another group of people who contracted COVID-19 but did not experience persistent symptoms (acute COVID Group), and a group of people who did not contract COVID-19 (Control Group). One hundred and twenty adults in each of the three groups will be recruited and will take part in three evaluations within 6 months (baseline and 3 and 6 months after baseline). At baseline, all participants will complete questionnaires on sociodemographics, COVID symptomatology and comorbidity, and self-reported questionnaires on quality of life, functional status, sleep, pain-related disabilities, anxiety, depression, fatigue and cognitive function. Then, physical and cognitive tests will be performed in a laboratory to provide complementary results on impairments and functional limitations. Finally, participants will wear a fitness tracker watch to monitor their activity and sleep for 7 days. The participants will complete the same measures (questionnaires, lab measures, fitness tracker watch) at 3 and 6 months after baseline evaluations. This project will lead to a better understanding of the impairments/limitations experienced following COVID-19. Hence, these results will allow to identify the interventions needed by the population and ensure these are offered through effective healthcare pathways.
An outbreak of Corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-coV-2) occurred in Wuhan city, Hubei province, China in December 2019. Pulmonary health has been the main focus of studies of COVID-19, current articles show that cutaneous signs appear in COVID-19 patients, their identification may be vital to early diagnosis and lead to possible better prognosis in COVID-19 patients
The investigators aim to carry out a retrospective observational study, analysing lung ultrasound images from patients who have presented to A&E for routine diagnostic purposes (ruling out cardiogenic pulmonary oedema, Pulmonary embolism and pericardial effusions) and systematically assessing for abnormalities typical for COVID-19 infection (Pleural irregularities, B lines, consolidations, pleural effusions). Doing this, the investigators will also develop a suggestion for a standardised technique for lung ultrasound which can be transferred to other clinical settings (Intensive Care, Acute medical Unit) and could form the basis for an international standard. Thirdly, the investigators aim to correlate our findings to clinical severity judged by oxygenation status on arrival in ED. To the investigators' knowledge, this is the first study of this kind.
Multi-center multinational-controlled study in Israel, Brazil, Spain, and South-Africa. 240 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 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 two dosages in addition to Standard of Care - Arm 1, 2 or (Placebo) in addition to Standard of Care- Arm 3.
The recently emerged coronavirus named Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV-2) is the newest threat to human health. It has already infected more than half a million people worldwide, leading to a lot of deaths. Patients with Coronavirus Disease 2019(COVID-19) will experience high levels of anxiety and low sleep quality due to isolation treatment. Purposes: Was to investigate the effect of aerobics and balancing exercises on anxiety and dizziness in patients with COVID-19. Subjects: Thirty anxiety and dizziness patients with COVID-19 aged from 45-65 years of both sexes, randomly divided into two groups, selected from outpatient clinic ,General
This study generates robust, uniform clinical data across emerging COVID-19 strains to train ML/AI algorithms of the Sponsor's imPulseā¢ Una infrasound-to-ultrasound e-stethoscope for digital diagnostic feature synthesis of asymptomatic and symptomatic COVID-19 digital biosignatures for rapid and accurate adult and child mass screening.
In order to assess the mother-to-infant and potential vertical transmission of SARS-CoV-2 infection in pregnant women, maternal and neonatal biological samples will be prospectively collected from women with confirmed or suspected COVID-19 at participating hospitals across Ontario. Samples will be tested for the SARS-CoV-2 serology and viral load. Outcomes for the study objective will be ascertained through the collection and testing of biological samples from the mother and/or infant. Specifically the investigators will: 1. Assess maternal nasopharyngeal or oropharyngeal swab, vaginal mucosa, ano-rectal swab, amniotic fluid, placenta (including subamniotic swab), breastmilk, cord blood and neonatal nasopharyngeal swab for RNA particles of coronavirus, by ddPCR. 2. Assess maternal serum for anti-coronavirus antibodies, by immunoassay. 3. Examine the impact of coronavirus on the neonate with respect to serology and viral load, in addition to placenta pathology findings and ddPCR. 4. Assess vertical transmission and the effect of coronavirus through placental pathology examination using placental pathology synoptic report.
This is a dose optimisation study in healthy adults aged 18-30 who will be experimentally inoculated with SARS-CoV-2. The aim is to cause PCR-confirmed upper respiratory infection in the majority of challenged individuals with minimal or no illness, providing data on the course of COVID-19 and the immune response to SARS-CoV-2 infection. This will establish an optimised dose and study design that will then be used to evaluate the efficacy of treatment and vaccine candidates plus level and duration of immune protection in follow-on trials.
The reason the investigators want to do this research; Especially after Covid-19 infection, no research has been found on functional status in the long term. Therefore, in our study, the investigators aimed to evaluate exercise capacity, functional status, peripheral muscle strength, balance, anxiety and depression level, consciousness, work productivity, pain, fear of movement, and quality of life in patients with Covid-19 and to compare them with healthy individuals who have not had COVID-19.
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.
