Filter by:Objective: To assess the prognostic value of high-sensitive cardiac troponin T (hs-cTnT) and N-terminal pro brain natriuretic peptide (NT-proBNP) at ICU admission in patients with coronavirus disease 2019 (COVID-19). Design: Multicenter retrospective observational cohort study Setting: Three ICUs at three hospitals in Occitanie, France. Patients: Adults (≥ 18 years old) with laboratory-confirmed COVID-19 and at least one hs-cTnT measurement at ICU admission, from March 9, 2020, to May 9, 2020.
The COVID-19 pandemic challenges available hospital capacity. Strategies to protect health care workers (HCW) are desperately needed. Bacille Calmette- Guérin (BCG) has protective non-specific effects against other infections; a plausible immunological mechanism has been identified in terms of "trained innate immunity". The primary objective of the study is to evaluate whether BCG can reduce unplanned absenteeism due to illness among HCW during the COVID-19 pandemic. Secondary objectives are to reduce the number of HCW that are infected with COVID-19, reduce hospital admissions for HCW and to improve the capacity for clinical research. Design: Single-blind, parallel-group placebo-controlled multi-centre block randomized trial including a total of 1050 HCW. The study sites will be the Manhiça hospital in Mozambique, Central Hospital Dr. Agostinho Neto and Central Hospital Dr. Baptista de Sousa in Cape Verde and Hospital Nacional Simão Mendes and other hospitals in the capital Bissau in Guinea-Bissau. Population: HCW (nurses/physicians/others) ≥18 years. Intervention: Block randomization 1:1 to intradermal standard dose (0.1 ml) of BCG vaccine or placebo (saline). Endpoints: Primary: Days of unplanned absenteeism due to illness. Secondary: Days of absenteeism because of documented COVID-19; cumulative incidence of infectious disease hospitalizations. Follow-up: mobile phone interviews every second week, regarding symptoms, absenteeism and causes, COVID-19 testing (if done) and their results. Perspectives: If BCG can reduce HCW absenteeism it has global implications. The intervention can quickly be scaled up all over the world.
The purpose of this study is to assess the effect of vitamin D and/or zinc supplementation on improving COVID-19 treatment outcomes. The effects of vitamin D, zinc, and both vitamin D and zinc together will be investigated among COVID-19 patients in India.
The aim of this observational study is to evaluate the physiological and clinical effects of prone position in awake patients with respiratory failure due to COVID-19.
This is a phase Ⅱ, single-center, randomized, double-blind, placebo-controlled study, to evaluate the immunogenicity and safety of the recombinant COVID-19 vaccine (Sf9 cells) in the subjects from healthy adults and elderly adults aged 18 years and above (aged 18-60 and 60-85 years) with different immunization procedures (0, 21 days and 0, 14, 28 days) and doses (20μg/40μg).
This study is a multicenter, randomized trial to study the potential benefit of treatments with a direct FXa inhibitor (rivaroxaban) versus standard of care dose subcutaneous low molecular weight heparin (LMWH) (Lovenox) in hospitalized subjects with COVID-19.
ACTT-4 will evaluate the combination of baricitinib and remdesivir compared to dexamethasone and remdesivir. Subjects will be assessed daily while hospitalized. If the subjects are discharged from the hospital, they will have a study visit at Days 15, 22, and 29. For discharged subjects, it is preferred that the Day 15 and 29 visits are in person to obtain safety laboratory tests, oropharyngeal (OP) swabs, plasma (Day 29), and serum for secondary research as well as clinical outcome data. However, if infection control or other restrictions limit the ability of the subject to return to the clinic, these visits may be conducted by phone, and only clinical data will be obtained. The Day 22 visit does not have laboratory tests or collection of samples and is conducted by phone. The primary objective is to evaluate the clinical efficacy of baricitinib + remdesivir versus dexamethasone + remdesivir as assessed by the mechanical ventilation free survival by Day 29.
Initial data from COVID-19 patients suggests that one of the primary causes of death is significant endothelial injury leading to blood clotting and impaired multiorgan microvascular perfusion. The current study uses a safe, convenient bedside imaging tool called contrast-enhanced ultrasound (CEUS) to estimate the extent of microvascular perfusion impairment in the heart, kidneys and/or brain of COVID-19 pediatric patients in vivo and assess the significance of imaging findings by correlating to clinical outcomes. This pilot study will be conducted at one site, The Children's Hospital of Philadelphia. The investigators plan to enroll and evaluate 30 patients.
The purpose of the research is to test out a new form of treatment that examines stimulation of a nerve in the participant's ear. This is called transcutaneous (through the skin) auricular (ear) vagus nerve stimulation (taVNS) which means that the participant will receive stimulation through the ear. The taVNS device looks like an ear bud used with a smart phone or computer. The study team is investigating whether or not taVNS can treat neurologic symptoms of COVID-19 which are termed NEUROCOVID. Some symptoms the participant may experience are new onset anxiety, depression, vertigo, loss of smell, headaches, fatigue, irritability, etc. This study is entirely online and all assessments will be completed virtually.
Screening programs have been associated with a substantial reduction in colorectal cancer (CRC) mortality through endoscopic resection of preneoplastic lesions and detection of early-stage invasive cancers. In March 2020, the World Health Organization declared as a pandemic the outbreak of coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2. Since then, the SARS-CoV-2 have never stopped spreading, causing an unprecedented situation with highly restrictive considerations to be adopted by the majority of countries worldwide. Health-care facilities have been making an enormous effort to assist patients affected by COVID-19, while adopting measures to maintain a safe environment for patients and healthcare professionals. As a result, the usual workflow in endoscopy departments changed dramatically, leading to an increase in cancelled procedures, probably increasing the future burden of Colorectal Cancer due to delays in diagnosis.
