Filter by:In children with Covid-19, the diagnosis of Kawasaki Disease (KD) and pneumonia should be made very quickly. However, the regional hospitals surrounding Paris don't have the required expertise. The use of MELODY allows the paediatric team to quickly carry out the necessary examinations while avoiding the movement of patients and the risk of contamination. The MELODY remote system developed by the company AdEchoTech is a CE marking telemedicine technique, allowing an expert to perform an ultrasound scan on a distant patient (several hundred/thousands of kms). The Melody system makes it possible to optimize ultrasound expertise resources wherever they are located (all specialties combined) The feasibility of the clinical use of telerobotic sonography has been demonstrated in adults for abdominal, cardiac and prenatal exam. Thus, the aim of this study is to assess the feasibility of this system in children.
The hypothesis of this work is that the COVID 19 pandemic and the associated lockdowns are likely to modify the adherence to positive airway pressure (PAP) treatments among patients with sleep apnea. Identifying these patients and identifying adherence "trajectories" over time would help mobilize human and telemedicine resources on the patients most in need.
Rheumatological diseases (RD) are an important group of different clinical entities and specific diseases that affect a significant proportion of the world population. In Mexico, the RD have a relevant representation in the adult population. COVID-19 vaccination has been proposed as a measure to contain the COVID-19 pandemic. The vaccines have been shown to be effective and reasonably safe in the population without significant risk factors, which has allowed their approval to attend the health emergency. At present, there is little scientific information that allows a solid recommendation on vaccination for COVID-19 in patients with RD, although most authorities have spoken in favor of vaccination in immunocompromised patients, as are a relevant number of patients with RD. However, it is desirable to achieve herd immunity to facilitate the impact of vaccination on the transmission of SARS-CoV-2 infection. For this, it is required that around 70% -80% of the target population be vaccinated, which implies not only access to the vaccine but also accepting to be vaccinated. Vaccine hesitancy is defined as the delay or refusal to accept the vaccine when it is available by health services. Sometimes, they conceptualize it as a continuum and also includes the high demand from the population for the vaccine; In this continuum, there are variations in acceptance and rejection and multiple possible combinations, from acceptance with great concern about the decision to rejection of certain vaccines but not others. It is a complex, contextual, changing phenomenon, specific for each vaccine and the referred disease and probably influenced by cultural determinants.
SARS-CoV-2 enters human cells through the binding of the spike protein with angiotensin converting enzyme-2 (ACE2), a membrane receptor highly expressed in immune or non-immune cells, and in many organs, including lungs and endothelial cells. In COVID-19 disease, the infection of endothelial might cause an acute endothelial dysfunction. The objective of this study is to demonstrate that patients COVID19 (+) hospitalized in ICU present an acute endothelial dysfunction (compared with COVID19 (-) also hospitalized in ICU). This acute endothelial dysfunction could lead to organ failure, systemic immune dysregulation and thrombosis.
Sofosbuvir has been recently recommended as a possible antiviral for COVID-19, based on structural studies and multiple alignment analysis. By comparing the positive-stranded RNA genomes of HCV and SARS-CoV-2, it has been postulated that sofosbuvir might be an optimal nucleotide analogue to repurpose for COVID-19 treatment
VBI-2902a and VBI-2905a are investigational vaccine candidates that use enveloped virus-like particle (eVLP) expression of a modified version of the SARS-CoV-2 spike (S) glycoprotein and are designed to induce neutralizing antibody and cell-mediated immune responses against the SARS-CoV-2 spike protein. VBI-2902a expresses the spike protein of SARS-CoV-2 Wuhan isolate (the first virus variant isolated in 2019 in Wuhan, China), while VBI-2905a expresses the spike protein of SARS-CoV-2 variant Beta (B.1.351 variant, first isolated in 2020 in South Africa). The Phase 1a portion of this study tests one- and two-dose regimens of VBI- 2902a with 5 μg S protein content and aluminum phosphate (alum) adjuvant or placebo delivered by intramuscular (IM) injection. The Phase 1b portion of the study tests a one-dose regimen of VBI-2905a with 5 μg S protein content and alum adjuvant or placebo delivered by IM injection in participants previously vaccinated with an authorized mRNA COVID-19 vaccine.
Introduction: School closures due to the COVID-19 pandemic represent a risk factor for the development of childhood obesity due to the increase in unhealthy behaviors. Online lifestyle interventions in schoolchildren could help to mitigate this problem. However, to date, no randomized controlled trials have been performed to prevent obesity in schoolchildren during the COVID-19 pandemic. The aim of this study is to evaluate the effect of a 4-month online lifestyle intervention on the BMI Z-score of Mexican schoolchildren during the COVID-19 pandemic in an intervention group compared to a control group. Methodology: This is a pilot randomized controlled trial. Schoolchildren from a public elementary school in Hermosillo, Sonora, Mexico will be invited to participate. Participants will be randomized to an intervention group (online lifestyle intervention) or a control group. The intervention will include online sessions of nutrition education and physical activity and nutrition information for parents. The control group will receive a digital brochure with nutrition recommendations at the beginning of the study. The measurements will be performed at baseline and 4 months. The primary outcome will be the BMI Z- score. Secondary outcomes: waist circumference, fat percentage, nutritional knowledge, lifestyle parameters, retention, attendance at the program sessions, and acceptability of the intervention. The difference between groups in changes in the outcomes will be analyzed using an intention to treat analysis. The protocol was approved by the Research Ethics Committee of the University of Sonora Nursing Department (EPM-003-2020). Conclusion: The study will provide the first evidence of the evaluation of online interventions for the prevention of obesity in schoolchildren derived from a Randomized Controlled Trial. This information will be important for the development and implementation of other school-level obesity prevention programs around the world.
Critically ill patients with COVID-19 are exposed to high oxidative stress which is potential harm to the DNA. Peripheral lymphocytes' DNA will be investigated using the comet assay on changes in oxidative damage to the purine and pyrimidine bases and single-stranded DNA breaks.
The SarcoV study aims at assessing the association between sarcopenia and the indication of mechanical ventilation in older hospitalized patients due to COVID-19 infection
As it is evident that Covid-19 may have some impacts on cognition, the primary aim of this study is to investigate -if any- deficits of attention, working memory and executive functions after Covid-19.
