Filter by:This is a prospective, randomized controlled trial that will evaluate the effectiveness of two different targeted outreach interventions aimed at increasing Covid-19 vaccine uptake. Veterans who are eligible for COVID-19 vaccine receipt by priority status (based on institutional guidelines) will be identified. Veterans must be enrolled into Veterans Health Administration (VHA) care and meet age or illness institutional priority guidelines to be eligible. Veterans eligible for enrollment into the trial will be randomized in a 1:1:1 allocation at an individual level, using permuted block randomization (with random block sizes of 3 and 6) to the following interventions: 1. Control arm - receives a text message with standard messaging 2. Arm 2 - receives a text message with a message framed for scarcity 3. Arm 3 - receives a text message with a message framed for improving the social good
This is a research study to evaluate the Sensitivity and Specificity of BIOZEK COVID-19 Antigen Rapid Test on samples collected by a healthcare professional versus self-collection; and to perform analysis to compare results. In addition, to obtain RT-PCR test results, performed prior to enrollment, and compare all three results.
This study aims to assess how an at-home COVID-19 frequent testing regimen using the CoV-SCAN test kit and a paired phone application to help interpret the test result compares to once-a-week or three-times-a-week polymerase chain reaction (PCR) (molecular) testing to identify a SARS-CoV-2 infection. Employees and cast members at Media and Entertainment Company and its affiliates will be recruited to test whether frequent use of CoV-SCAN will perform as well or better than weekly molecular testing and at least as well as three-times-a-week molecular testing.
Lung ultrasonography (LUS) is also used in COVID 19 pneumonia for diagnostic and follow-up purposes.It has been demonstrated in different studies that it can be used for pathologies in pleural and lung tissue. LUS was applied by different researchers by dividing the lungs into 12 and 14 regions and the results were shared.
This placebo controlled study is intended to generate safety and efficacy data in order to provide a treatment option for COVID-19 in patients with a high risk of disease progression based on age or co-morbid medical conditions.
Studying clinical characterization of critically ill COVID-19 patients in a single center Studying Risk factors for Day 28 Mortality in COVID-19 patients admitted to intensive care unit
This is a prospective cohort study aimed to evaluate short- and mid-term immune response after SARS-CoV-2 vaccination using Gam-COVID-Vac (Sputnik V) vaccine in dialysis patients compared to the control group (medical staff).
The UK Medicine and Healthcare products Regulatory Agency (MHRA) granted temporary authorisation to three Covid-19 vaccines in December 2020 and January 2021. These vaccinations include: - Covid-19 mRNA BNT162b2 vaccine (Pfizer-BioNtech vaccine); - ChAdOx1-S vaccine (Astra Zeneca vaccine); - Covid-19 mRNA vaccine (Moderna vaccine). Any other Covid-19 vaccines approved for use by the MHRA in immunocompromised and immunocompetent patients are to be included in this study. The above vaccines have received temporary authorisation after placebo-controlled phase 3 studies confirmed their safety and efficacy in over 100,000 volunteers. People who were immunocompromised or were receiving chemotherapy, radiotherapy or immunoglobulin treatment were excluded from these studies. Safety, efficacy, and durability of antibody response in these studies has been assessed for up to 14 weeks only. These vaccines are being rolled out in the UK and have been recommended for use for immunosuppressed individuals including patients undergoing chemotherapy, immunotherapy, radiotherapy, and those who have undergone stem cell transplantation. Though the MHRA has approved vaccination for immunocompromised patients there is no published evidence to confirm safety and efficacy in these patients. The durability of antibody response and whether this is affected by concurrent chemotherapy, immunotherapy, radiotherapy treatment is also unknown. This observational study aims to evaluate the immune response to Covid-19 vaccines in haematology patients who have immune suppression either due to disease, treatment, or both. The investigators plan to measure Anti-SARS-COV2 IgG antibody levels at 3-5 time points 30 days apart after patients have received their 2nd dose of Covid-19 vaccine. The investigators will also collect any adverse events reported by patient including Covid-19 infection or disease after vaccination. The study plans to recruit 50 haematology patients who are clinically assessed by a haematologist as immunosuppressed due to their disease, treatment, or both. The study also plans to recruit 30 healthy (immunocompetent) volunteers who would be the control group for comparison of antibody response and durability.
Among all MM patients included in the cohort at the time of diagnosis of SARS-CoV-2 infection, blood samples will be collected at inclusion, at time of the infection acute phase in the most severe cases (when admitted in intensive care units), and at recovery. The following immune function tests will be evaluated, gammaglobulin measurements, lymphocytes counts, B, T, and NK cells analyses by cytometry, including exhaustion analyses. In addition, T cell repertoire sequencing looking for SARS-CoV-2- specific T cells, and serologies, will be evaluated at recovery and 6 months after MM treatment re-initiation.
Up to a third of patients who recovered from SARS coronavirus (SARS-CoV) had a 20% decline in lung function with a long term reduction in exercise capacity and SF-36 health status a year after infection. Similar outcomes are now being reported in COVID-19 patients, with interstitial lung disease (fibrosis) and long term lung function decline being a common feature. Anti-fibrotic monocytes/macrophages are important for the clearance of partially degraded collagen fragments of fibrotic extracellular matrix, in particular fibrillary-type collagen. MON002 is an autologous monocyte product, cultured in vitro prior to intravenous delivery into patients with post-COVID-19 lung fibrosis.
