Filter by:In this trial the researchers plan to recruit 25,000 volunteers to be randomly allocated either wearing sunglasses or ordinary glasses in public spaces where they are close to other people, or not wear glasses in such circumstances. For each participant the trial period is 2 weeks, after which they will be asked to complete a brief questionnaire which includes questions about results of COVID-19 tests during the trial period.
Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres throughout the United Kingdom. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. We will also examine the effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination we will perform a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time.
To compare the outcomes of HFNC and HVNI in COVID-19 patients with acute respiratory failure as regard need for mechanical ventilation, changes of arterial blood gases (ABG) parameters, duration of ventilatory support and delay between admission and intubation
In view of the recent COVID surge and difficulties in obtaining testing, we aim to increase Point of Care (POC) testing, whereby University of Pennsylvania (Penn) faculty, staff, and trainees who are working in person at Perelman School of Medicine (PSOM) laboratories can self-test. The purpose of this study is to evaluate the implementation of this POC testing program. We will not be collecting any samples as part of this study. This will ensure that individuals can rapidly identify if they have COVID-19 while balancing use, acceptability, appropriateness, and feasibility. We will start with a pilot phase whereby we will evaluate the implementation of a POC version of COVID-19 screening program that will coordinate several existing systems at the University of Pennsylvania including voluntary, self-administered saliva-based viral testing. We will pilot this program to a small cohort of PSOM labs and then test implementation of the self-testing of the POC version of COVID-19 screening across all PSOM labs for those who wish to participate. All results will be self-reported and will not be used to validate any tests or support any future approval from the FDA. No data from this study will go into the participants' Electronic Medical Record (EMR).

The purpose of this study is to assess the safety, tolerability, and immunogenicity of a booster dose of vaccine in participants who are generally healthy or with stable pre-existing health conditions. Study details include: - The study duration per participant will be approximately 209 days (28 days screening, 1 day vaccination, and 180 days follow-up). - The treatment duration will be 1 day. -The visit frequency will be 6 on-site visits (1 screening visit, 1 treatment visit, and 4 follow- up visits) and 1 phone visit.
This prospective cohort of patients, receiving pre exposure prophylaxis by Anti-SARS-CoV-2 Monoclonal Antibodies, is designed to evaluate the treatment protection against SARS-CoV-2 variants of concerns
In COVID-19 infection caused by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is a dysregulation of the immune system response that causes cytokine storm syndrome. SARS-CoV-2 works like a hijacker (hackers), sabotaging communication between cells so that the immune system, like T-cells, kills not only infected cells but also healthy cells. This dysregulation results in hyper-inflammation which cause damage to organs, not just the lungs. This is the cause of the high mortality rate in COVID-19 patients. Exosomes are vesicles with a size of 30-100 nanometers originating from within cells that function to communicate with other cells. Exosomes are transport containers that contain bioactive cargo: such as proteins, genetic material, and various other molecules. These containers move from cells of origin, flowing through blood vessels or other body fluids to target cells. Exosomes penetrate the cell membrane and act on various organelles within the target cell. All cell types can produce exosomes. What differentiates them is the cargo they contain. The exosome produced by mesenchymal stem cells (MSCs) contains bioactive cargo derived from mesenchymal stem cells, such as anti-inflammatory cytokines, growth factors, messengerRNA (mRNA) and microRNA (miRNA). The target cells are immune system cells, infected cells and progenitor cells from infected organs. On target immune cells, the anti-inflammatory cytokines work as immunomodulators to relieve hyper-inflammation. In infected cells, the miRNAs work to prevent viral replication by inhibiting the expression of SARS-CoV-2 virus RNA (viral mRNA silencing and degrading). In lung progenitor cells and other infected organs, the growth factors work to stimulate protein synthesis processes that function for organ regeneration. This study is a multi-center, double-blind, randomized controlled trial (RCT) clinical trial with two arms: one intervention arm, and one control arm. The EXOSOME-MSC will be tested as adjuvant, on top of standard COVID-19 drugs. It will be injected to participants via intravenous route twice, in day-1 and day-7 of 14 days of study participation.
The latest data indicate that post COVID-19 condition is frequent in children and adolescents, with the most common symptoms being fatigue, shortness of breath, exercise intolerance and weakness. Evidence that COVID-19 can have significant long-term effects on children's health highlights the need for measures to reduce the impact of the pandemic on children, ensuring that they receive appropriate treatments. Those experiencing post COVID-19 condition require more tailored exercise-related advice and improved support to be able to resume activities important to their individual well-being. To the best of our knowledge, no studies have yet addressed the issue of exercise programs for children with post COVID-19 condition. The aim of this study, therefore, is to evaluate the effectiveness of different interventions on pulmonary function, exercise capacity, fatigue and quality of life in children with post COVID-19 condition. This will be a randomized controlled study with pre and post intervention assessment. Children will be recruited from primary schools and primary health care units in Warsaw. Participants meeting the inclusion criteria will be randomized to one of 3 groups: water-based exercise, land-based exercise or control (no exercise). The water-based and land-based exercise groups will be held twice a week, 45 min per session for 8 weeks. Participants will be assessed at baseline and immediately post-intervention in terms of changes in pulmonary function, exercise capacity, fatigue and quality of life. Research outcomes will build the evidence-based practice for health professionals.
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.
