Filter by:Is precariousness a risk factor for COVID-19 mortality in intensive care units ? Abstract Background: During the SARS-CoV-2 pandemic, the first wave overwhelmed hospitals in Paris area (Ile-de-France) with a variable impact depending on the territory. Several studies highlighted variable ICU mortality rates during COVID-19 surges across territories (10 to 60%) with higher rates in those most affected by poverty. We assessed the impact of precariousness, as an independent risk factor, on mortality linked to Covid-19 between ICUs at Delafontaine hospital and Ambroise Paré hospital. Method: Investigators carry out a retrospective observational cohort study of consecutive ICU patients aged ≥ 18 years admitted at Delafontaine and Ambroise Paré hospitals during the first wave of the Covid-19 outbreak in order to compare mortality rates according to predefined risk factors (age, diabetes, arterial hypertension, BMI, active solid or haematological cancer, IGS2, poverty rate at the threshold of 60% (%) according to the island grouped for statistical information (IRIS)37 of the patient, invasive ventilation or not) that include precariousness. Results: Conclusion:
Contrasting hypotheses, including that of a protective role of nicotine, have been generated concerning the association between smoking and the occurrence of COVID-19 infection. The question has attracted a lively scientific and public debate. However, the studies conducted so far are based on clinical samples, with a majority of hospital case series, thus most likely suffering from bias due to selection. The investigators propose to conduct an analysis of the potential causal association between smoking or the use of the Swedish smokeless tobacco snus and the occurrence of COVID-19 using data from a newly identified retrospective cohort in Sweden. Information on tobacco use will be extracted by public dental clinic records in Stockholm Region between October 2015 and January 2020. Information on diagnoses of COVID-19 will be obtained through record linkage with health care registers of inpatient and outpatient care during the period February 2020-August 2021. Socio-demographic information will be accrued from the register of the total population in Stockholm Region (Statistics Sweden). The risk of COVID-19 for tobacco users compared to non-tobacco users will be calculated as a measure of association adjusting for potential confounders.
The aim of the study is to gain insight into the rehabilitation process and predictive factors for the outcome after rehabilitation in three patient groups: 1. SARS-CoV-2-positive patients in the isolation ward 2. Post-Covid-19 patients 3. Control group; matched for gender, age and co-morbidity
COVID-19 is respiratory disease caused by the severe acute respiratory coronavirus 2 (SARS-CoV-2), a novel coronavirus which has spread rapidly across the world with over 149.9 million laboratory confirmed cases and over 3.1 million reported deaths since December 2019. Approximately 4-8% of hospitalized patients with COVID-19 have co-infection with bacterial pathogens however there is widespread and often broad-spectrum antibiotic use in these patients. This is a prospective, multi-center, non-inferiority pragmatic clinical trial of antimicrobial stewardship prospective audit and feedback versus no antimicrobial stewardship intervention on physicians attending to patients with proven SARS-CoV-2 infection confirmed by nucleic acid testing in the preceding 2 weeks of hospitalization for acute COVID-19 pneumonia. Prospective audit and feedback is the real time review of antibacterial prescriptions and immediate feedback to prescribers to optimize antimicrobial prescriptions. Hospital beds will be stratified by COVID unit and critical care unit beds, and will be computer randomized in a 1:1 fashion into 2 arms (antimicrobial stewardship intervention versus no antimicrobial stewardship intervention) prior to study commencement at the participating site. Patients hospitalized to study-eligible beds will be followed for primary and secondary outcomes. The objective of this study is to determine the effect of an antimicrobial stewardship intervention (prospective audit and feedback) on clinical outcomes in patients hospitalized with acute COVID-19.
AZD7442 mAbs are being evaluated for administration to prevent or treat COVID-19. This Phase I study will gather important information on the safety and tolerability of AZD7442.
This is a 4 dose study with 124 participants (7 adults ,117 children). Adults are considered to be participants 18 years of age or older. Participants are going to be enrolled based on conditions that make them immunocompromised. Participants are going to be followed up for 6 months after dose 4, and each participant is projected to be on the study for approximately 15 months. This study will be conducted in the United States, Brazil, Germany and Mexico.
Case-series and cohort studies have shown the feasibility of reperfusion therapies in patients with ischemic stroke and COVID-19, but due to the absence of a contemporary control group of non-COVID-19 patients, small sample size or lack of long-term outcome assessment, concerns regarding safety and efficacy of these treatments remain to be clarified. Taking into account its limitations, some studies documented higher rates of endovascular treatment complications such as clot fragmentation with distal embolization and vessel re-oclusion, to be more difficult to achieve recanalization after endovascular treatment, and higher rates of any intracerebral hemmorhage. The investigators aim is to assess in a large, multicenter and international cohort, the safety and outcomes of acute reperfusion therapies in patients with ischemic stroke and COVID-19, by comparison with a contemporary control group of patients with ischemic stroke and without COVID-19 from the same centers.
Multi-center phase Ib study to evaluate the Modified Vaccinia Virus Ankara (MVA) vaccine against SARS-CoV-2 in seronegative (Part A) and previously SARS-CoV-2-vaccinated individuals (Part B).
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), is a multisystem infectious disease which has led to a global pandemic. Tele-medicine is a tool to connect patients and health care professions while maintaining social distancing and restrictions. Tele-physiotherapy is a field of physiotherapy which has the advantage of providing therapy. Since some months ago, different organizations have started the tele-physiotherapy/tele-rehabilitation program to manage the patients' complications after COVID-19. This research team have developed a tele-rehabilitation guideline for physiotherapists to help them how to use tele-physiotherapy program for patients after COVID-19 hospitalization. The aim of this study is to evaluate the efficacy of tele-physiotherapy program in patients discharged after COVID-19.
The purpose of this research study is to learn about the factors parents consider when deciding whether their child will go to school in-person or attend from home. Investigators are also interested in learning whether access to in-home COVID testing is of value to parents and also whether it affects decision-making about returning to school. This study is being done at UW-Madison in partnership between the Department of Pediatrics and the Department of Industrial and Systems Engineering. A total of 50 caregivers (plus their children with medical complexity) will participate in this study. Additionally, 20 caregivers involved in the study may also be invited to participate in a one-hour, virtual visit in which the caregiver demonstrates and discusses how they perform in-home COVID testing with their child. The results of the study may help researchers advance their understanding of in-home testing strategies for children with medical complexity.
