Filter by:Hero-19 aims to evaluate if an intensive anticoagulation strategy using Edoxaban on top of standard of care (SOC) of COVID-19 therapy is superior to SOC (in-hospital moderate anticoagulation strategy = low-dose low-molecular weight heparin [LMWH], ambulatory no anticoagulation, i.e. placebo within this trial) in reduction of morbidity and mortality endpoints in patients with COVID-19.
Background: The virus SARS-CoV-2 has spread rapidly throughout the world. Seniors are at high risk of severe COVID-19 when infected. Bacille Calmette-Guérin (BCG) is a vaccine against tuberculosis, with protective non-specific effects against other infections; significant reductions in morbidity and mortality have been reported, and a plausible immunological mechanism has been identified: "trained innate immunity". The investigators hypothesize that BCG vaccination can reduce the risk of COVID-19 and other infections among senior citizens during the COVID-19 pandemic. Objectives: Primary objective: To reduce senior citizens' risk of acute infection during the COVID-19 pandemic. Secondary objectives: To reduce senior citizens' risk of SARS-CoV-2 infection during the COVID-19 pandemic. To reduce senior citizens' risk of self-reported respiratory illness during the COVID-19 pandemic. Study design: A placebo-controlled randomized trial. Study population: 1900 seniors 65 years of age or above. Intervention: Participants will be randomized 1:1 to intradermal administration of a standard dose of BCG vaccine or placebo (saline). Outcomes: Primary outcome: "Acute infection" identified either by a doctor, antibiotics use, hospitalization, or death due to infection. Secondary outcomes: Verified SARS-CoV-2 infection and self-reported respiratory illness. With an expected incidence of "acute infection" of 20%, the trial can show a 25% risk reduction in the the intervention group versus the placebo group by including a total of 1900 individuals, 950 individuals in each group. Risk for participants and impact: Based on previous experience and randomized controlled trials in adult and elderly individuals, the risks of BCG vaccination are considered low. If BCG can reduce the risk of acute infection in seniors by 25% it has tremendous public health importance, both during the COVID-19 pandemic and overall.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been a world health issue during the last months, affecting mostly countries with a high metabolic risk, like Mexico. Patients with type 2 diabetes (T2D) have an increased risk of any kind of infection as well as an increased mortality risk. Hyperglycemia has been established as an important predictor of mortality in patients with T2D and SARS-CoV-2. The standard treatment of hyperglycemia in hospitalized patients has been basen on insulin schemes, but recently evidence suggest the utility of some other drugs, reducing the risk of hypoglucemia and increasing the probability of a proper metabolic control. The goal of this study is to compare the utility of dipeptidyl peptidase-4 inhibitor (DPP4i) as a combination with insulin on metabolic control and prognosis in hospitalized patients with SARS-CoV-2 and hyperglycemia.
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 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.
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.
The rapidly spreading coronavirus Covid-19 pandemic is a major concern worldwide and Italy is at the forefront of this emergency. At the present moment, the effects on the offspring of Covid-19 disease in pregnant women and/or the indirect effect of COVID-19-related prenatal maternal stress are poorly understood. Epigenetic mechanisms - and especially DNA methylation - are involved in the embedding of prenatal exposures to large-scale disasters into the epigenome and phenotypic outcomes of the offspring. Specific target genes include SLC6A4, NR3C1, OXTR, BDNF, and FKBP5. The central hypothesis of this project is that the exposure to the COVID-19-related prenatal maternal stress may affect infants' outcomes from birth to 12 months partially through increased methylation of target genes involved in stress regulation. The main goal is to investigate the association between Covid-19 disease in pregnancy or COVID-19-related PMS in women pregnant during the first 9 months of the year 2020 and the emotional, social, and cognitive developmental outcomes in their infants from birth to 12 months. Additionally, the role of target genes methylation in mediating this association will be investigated. Mothers and their infants will be enrolled from the delivery units of eleven neonatal facilities located in Northern Italy's COVID-19 contagion hotspot. One group will be enrolled from April to October 2020 (COVID-Exposure Pregnancy, CEP), a second group will be enrolled from April to October 2021 (Non-Exposure Pregnancy, NEP). Moreover, the CEP group will include mothers positive or exposed to COVID-19-related MPS during different trimesters of pregnancy, allowing within-group comparisons on developmentally sensitive time windows. Within 48 hours from baby delivery, saliva samples will be obtained from CEP and NEP newborns, immediately stored at -20°C and analyzed for epigenetic analyses using Next-Generation Sequencing. At 3 and 6 months, mothers will be asked to fill-in validated and reliable questionnaires on the emotional and social-behavioral development of their infants. At 12 months, infants' stress regulation and maternal sensitivity will be evaluated through video recording of mother-infant interactions. This study will provide unprecedented relevant insights on the biochemical mechanisms underlying the impact of Covid-19 disease and the related PMS on human offspring's developmental outcomes.
