Filter by:Prone position (PP) is standard of care for mechanically ventilated patients with severe acute respiratory distress syndrome in the intensive care unit (ICU). Recommendations suggest PP durations of at least 16 hours. In 2020, COVID-19 pandemic led to a great number of patients requiring mechanical ventilation and PP in the ICU. Risk of ICU staff viral contamination and work overload led to prolongation of PP duration up to 48 hours. Here investigators report outcomes of prolonged PP sessions in terms of skin complications (pression injuries) and ventilatory improvement.
The vaccination campaign in France began in early 2021 and was declared mandatory for all French people in July 2021. The efficacy of COVID-19 vaccines has since been widely demonstrated, as well as their safety, and now 60% of the adult population in France has received a first dose, most of them with Pfizer-BioNTech's mRNA vaccine. However, despite the increasing coverage, new data highlight the need for a booster dose for the most vulnerable people, including patients with immune deficiency. This makes it likely that a booster dose will also be needed in the general population, especially among healthcare workers, due to the active circulation of new variants since the beginning of summer 2021 and evidence of reduced protection against them. On the other hand, in addition to evaluating the potential benefit of a booster vaccination, it appears interesting to also evaluate a heterologous vaccination regimen, i.e. a booster with a different vaccine than the one used for the primary vaccination. Some studies have already evaluated a two-dose heterologous regimen and the results have shown stronger protection against SARS-CoV-2. In addition, this alternative could provide a real benefit in terms of accessibility, cost, and acceptability. The vaccine developed by Sanofi-Pasteur is based on a traditional recombinant protein approach using GSK's AS03 adjuvant. Two formulations of this vaccine are currently under development, the first targeting the S protein of the D614 strain (Wuhan strain), the second targeting the B.1.351 variant. Their value as a booster needs to be evaluated. The objective of this trial is therefore to evaluate the immunological response and safety induced by a homologous vaccine booster (Pfizer-BioNTech vaccine booster) and a heterologous vaccine booster (one of the two experimental Sanofi/GSK vaccines booster), on the D614 (Wuhan) strain and on the SARS-CoV-2 variants.
The COVID-19 pandemic represents the most serious global health threat since the Spanish influenza, with repercussions on physical and mental health. The balance between physical and mental state is essential when establishing treatment for a critically ill patient and must be taken into account by health professionals. Therefore, the investigators hypothesize that there is an association between the severity of the clinical picture of COVID-19 and psychiatric morbidity. Objective. Associate the severity of the clinical picture of COVID-19 with psychiatric morbidity. Material and method. Hospitalized participants in the COVID respiratory area at the General Hospital of the Zone will be included. # 51 of Gómez Palacio, Dgo. in the period from October 1, 2021 to March 31, 2022. This is an epidemiological, observational, prospective, longitudinal, analytical study. Sociodemographic, clinical and psychiatric evaluation data will be obtained using GMHAT / PC. A statistical analysis will be carried out using descriptive statistics (frequencies, measures of central tendency and dispersion) and analytical, to evaluate the association (Chi2) and to evaluate the effect of the intervening variables (binary logistic regression and multivariate regression). The data will be analyzed in the SPSS version 21 program.
As few data are available on the epidemiology of the COVID-19 in primary care, the project aims to implement a practice-based surveillance network based on multiprofessional health homes in the French region Auvergne-Rhône-Alpes (Aura), able to monitor the evolution of the current epidemic.
This project capitalizes on a natural experiment imposed by the COVID-19 pandemic in conjunction with an extensive set of cognitive, emotional, biological, and neuroimaging variables already collected at multiple time points in older adults participating in a clinical trial of exercise and mindfulness. This project will elucidate the effects of stress on cognitive function and emotional health in later life, including biological measures of Alzheimer Disease risk, stress, and aging, with the ultimate goal of discovering how to mitigate these effects, among older adults who have made and maintained a lifestyle change.
A Phase 2a, randomized, double-blind, placebo-controlled, multiple ascending dose study in patients who are hospitalized with presumed pneumonia requiring supplemental oxygen therapy. The purpose of this study is to examine the safety, tolerability and efficacy of AV-001 Injection administration daily to the earlier of day 28 or EOT (day prior to hospital discharge). A total of 120 eligible patients (20 patients in each of cohort 1, 2 and 3 and 60 patients in cohort 4) will be recruited from up to 25 participating institutions/hospitals. Patients will be randomized in a 1:1 ratio to receive either AV-001 Injection or AV-001 placebo Injection, together with standard of care (SOC).
The study team will conduct a feasibility study to develop and test out procedures for improved triage and COVID-19 testing in dental practices to increase safety and perceptions of the safety of Dental Health Care Workers (DHCW) and their patients. DHCWs in offices with Practice-Based Regional Network (PBRN) members and their patients will be recruited to participate in one of two protocols. The first, point-of-care (POC), will test out procedures for point-of-care SARS-CoV-2 antigen testing in the dental office along with enhanced triage using pulse oximeters. The second, laboratory (LAB), will test out procedures for a saliva-based laboratory SARS-CoV-2 viral test along with enhanced triage. The feasibility of implementing COVID-related testing and enhanced triage procedures in the dental setting will provide preliminary data to inform a larger network-wide study grant application.
This study evaluates the impact of an intervention to increase COVID-19 prevention behaviors, including COVID-19 testing. The intervention will be developed through a crowdsourcing contest.
Our primary objective is identifying the degree of self-perceived competence in medical students without clinical rotations during the COVID-19 pandemic to know how prepared the students could be when they are professionals because they lack clinical skills in front of an actual patient and can be affected to be accepted in hospitals because they will have to acquire a phase of training later. Without a clinical rotation, one can be deprived of the essential educational value.The study design is an observational cross-section study in which an anonymous survey will be shared online on Google Forms platform. Students will be asked for their participation; after obtaining verbal and consent, the survey will be distributed using social media groups such as foundation school groups. For this study, the Spanish version of the Self-Perceived Competence scale will be used (REF). This scale is comprised of 21 questions divided into five factors that assess: 1) demonstration of the essential clinical skills, 2) demonstration of clinical reasoning, decision making, and problem-solving skills, 3) management of life-threatening medical conditions, 4) management of common medical problems and 5) placing patients' needs and safety at the center of the care process. Each item has a Likert scale answers of 4 options ranging from "incompetent (1)", "somewhat incompetent (2)", "somewhat.
This is the first-in-human clinical study to see if a single dose of an investigational nasal spray made from a modified plant protein called Q-Griffithsin is safe, tolerated and acceptable for use by healthy adults 18 to 60 years of age.
