Filter by:The goal, with this study, is to leverage Northwell Health System's diverse workforce and robust testing structures, to contribute data-driven, evidence-based strategies to better understand the sustained prevalence of antibodies and how conferred immunity may be modified by environmental factors. The objective is to investigate the COVID-19/SARS-CoV-2 disease prevalence and trajectory over time, by conducting follow-up antibody testing on employees who consented to participate in research during the initial workforce offering. From 70,812 employees contacted, 46,117 were tested and received initial results. Of those participants, approximately, 32,000 agreed to be re-contacted, and 34,000 consented to research. The investigators plan to conduct an additional five rounds of testing that would sample individuals over a two-year period. This study is significant because it leverages Northwell Health's advanced laboratory systems to conduct serosurveillance of antibodies to COVID-19/SARS-CoV-2 across a large and diverse workforce, while taking into account the contextual environmental and occupational exposures that may modify continued immunity to the virus. Northwell Health's employee health services (EHS) is poised to act quickly to adapt policies and practices, where needed, to protect the workforce. The study is also innovative because it will be linking work environment and community measures with COVID-19 seropositive prevalence patterns over time, to build a better understanding of the disease and its controls at the population level. The expected outcomes include serial serology results as a measure of full or partial short-term (6 months) and long-term (2 year) immunity to re-infection and recognition of local environmental factors (e.g., building ventilation rates, zip code, air quality indicators) that could modify this immunity and assist with protecting the workforce and surrounding community. These results could inform national and global policies.
The COVID-19 pandemic has had dramatic effects on health systems and on non-COVID health care. Using French inpatient claims data and retrospectively collected clinical data, the investigators will assess the changes in hospital admissions for acute cardiovascular and neurovascular conditions in France during and after the national lockdown.
The purpose of this study is to evaluate the strategy of investigators for outpatients SARS-CoV-2 moderate pneumonia management in terms of efficacy and patient safety. The investigators ultimate goal is to validate first wave management strategy in order to support the investigators future approach in the event of a second wave, and spare the hospital resources by safely keeping at home as many patients as possible.
The COVID-19 pandemic represents a threat to rheumatology patients. National advice for patients to 'shield' is based on risk stratification of therapies and other risk factors. While the epidemiology of COVID-19 in the rheumatological population is largely unknown large case registries are beginning to show potential drug treatment interactions. Strict self-isolation (shielding) has been recommended for those deemed 'high risk' although its impact on the likelihood of COVID-19 infection and health related quality of life (HRQoL) is unclear. The study aims to explore how this unprecedented situation has impacted the Trust patients primarily evaluating prevalence of the infection, effect of stringent social distancing (shielding) and Quality of Life (QOL). This will be done via a voluntary questionnaire, sent via text messaging at 6 and 12 months.
Recent observations have suggested a role of neutrophil extracellular traps (NETs) in the pathophysiology of severe COVID-19. The aim of the study is to assess efficacy and safety of aerosolized DNase I to remove NETs and decrease respiratory distress in patients with COVID-19.
This study is designed to assess the safety and tolerability of single doses of DWRX2003 in COVID-19 patients.
Methods: Single-center pilot study included PCR+ SARS-CoV2-patients, hospitalized from April to May 2020 in Puebla, Mexico. Comparative treatment with steroids plus CsA or steroids. Mild, moderate or severe pneumonia was measured by clinical, laboratory tests, lung damage score by computed tomography, and score for clinical improvement. Death rate was evaluated at 28 days.
This study is a community hospital-based study that will enhance information being obtained in similar studies taking place in France, Denmark, and China. These studies are designed to assess risk of healthcare workers during outbreaks of Coronavirus 2019 (COVID-19) also known as sudden acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). This will be a prospective, single-center observational study involving human subjects. IgG (Immunoglobulin G) antibody will be tested in the serum of physicians working at Advocate Lutheran General Hospital (ALGH). IgG antibodies are the antibodies that form in response to viral or bacterial infections and typically reflect protection against said infection. To date, there have been no studies confirming that IgG antibody formation confers immunity, but studies are ongoing. Furthermore, data is lacking showing conclusive persistence of (possibly protective) antibodies over time. Attending physicians on the medical staff, fellow physicians, and house staff residents who worked at ALGH from March 1st, 2020 and on, will be eligible for the study. Testing will involve a venipuncture to obtain approximately 3mL of blood to be sent to ACL Laboratories for SARS-CoV-2 IgG testing. For physician subjects, this will be performed on four separate occasions, once at the onset of the study, a second test 3 months after the first test, a third test 6 months from the time of the first test, and a fourth and final test 12 months after the initial test. Two household members (defined below), one-time testing will occur within 2 weeks of the physician subject testing positive. All testing will be performed in a two-week window. All physician subjects will be tested at a centralized site that is only serving these subjects, by appointment. We will be offloading testing for household members to one localized commercial ACL site on the ALGH campus at the Center for Advanced Care. The household member testing will be extended to an additional two-week period after the two week window in which physicians are tested for a total of four weeks maximum. One-time testing for IgG antibodies to COVID-19 will be offered to a maximum of two household members, as defined as, any person over the age of 18 years old who has lived at home with the physician, who has tested positive for IgG antibodies, for at least 2 weeks in total duration since March 1st, 2020. The physician will be permitted to choose who gets tested, and the chosen adult subject will provide their independent consent to be tested.
This study is a phase III clinical trial to evaluate efficacy, reactogenicity and safety of the vaccine Ad5-nCoV compared with placebo in volunteers at the age from 18 to 85 years，with the randomized, double-blind design
This open-label, randomized, and controlled clinical trial aims to determine the feasibility and effectiveness of using NBT-NM108, a novel botanical-based fixed-combination drug, to modulate the gut microbiota and treat early-stage suspected or confirmed symptomatic COVID-19 patients.
