This is a phase III, randomized, observer-blind, active-controlled, parallel group, multi-center study to compare the immunogenicity and safety of a preventive COVID-19 vaccine EuCorVac-19 to ChAdOx1 in healthy adults aged 18 years and older
This paper is intended to report our observational study in evaluating the impact of the COVID-19 pandemic on Tan Tock Seng Hospital hepatopancreatobiliary unit's surgical workload from January to June across 2019 to 2022, corresponding to the pre-pandemic baseline to its peak and the gradual normalization of hospital services as Singapore entered the transition phase to COVID-19 resilience.
This research was characterized as a cross-sectional observational study, following the recommendations of the STROBE instrument. Therefore, it was conducted in the Intensive Care Unit of Otávio de Freitas Hospital (HOF) in Recife/PE, with patients over 18 years old who had a clinical diagnosis of COVID-19, using two methods of oxygen therapy (Nasal Oxygen Therapy) and (non-rebreather mask). Consequently, clinical evaluations were performed regarding the disease, severity of COVID-19, perception of respiratory effort, and electromyography of respiratory muscles. 1. Leading Question: How does the recruitment pattern of diaphragmatic and extradiaphragmatic muscles in patients with acute hypoxemia caused by COVID-19 behave when assessed through EMGs, considering the SpO2/FiO2 ratio as the analysis parameter? 2. Leading Question: Is there a relationship between the respiratory work estimated by electromyographic activity of diaphragmatic and extradiaphragmatic muscles in patients with acute hypoxemia due to COVID-19 and the parameters of respiratory frequency and levels of acute hypoxemia measured by the SpO2/FiO2 ratio? The rationale for this study is that the COVID-19 pandemic has caused significant impacts on global public health due to the high volume of respiratory complications in the face of a limited supply of healthcare resources, consequently leading to high mortality. Complications are initially manifested by acute hypoxemia associated with COVID-19 infection, sometimes silent upon visual inspection or using less sensitive methods. This complicates the management of compensatory respiratory work for hypoxemia, even with oxygen therapy support. Respiratory muscle recruitment involves aspects of inspiratory effort and ventilatory mechanics. Recognizing the presence and recruitment pattern of muscles involved in a timely manner can contribute to the clinical management success rate of individuals affected by respiratory dysfunction associated with COVID-19, especially at different levels of acute hypoxemia. Surface electromyography is a non-invasive, low-risk tool compatible with the analysis of respiratory muscle recruitment patterns. However, there are no studies describing this pattern in COVID-19 patients, serving as a basis for personalized therapeutic strategies.
This before-and-after study aims to evaluate the usefulness and efficacy of a personalized computerized cognitive training (CCT) to improve cognitive function among people with post-acute sequelae of COVID-19 (PASC).
The purpose of this study is to learn about the safety and effects of nirmatrelvir/ritonavir for the potential treatment of COVID-19 rebound. The study is seeking participants who: - Have completed treatment with nirmatrelvir/ritonavir - Have a rebound in COVID-19 symptoms - Are SARS-CoV-2 (COVID-19) positive All study medications will be taken 2 times a day by mouth for 5 days. The first dose of study medication is taken at the study clinic and the rest at home. We will examine the experiences of people receiving the study medicines to those who do not. This will help us determine if the study medicines are safe and effective. People taking part will be in this study for about 24 weeks. Enrolled participants will need to visit the study clinic at least 8 times during the study.
The rate of nosocomial SARS-CoV2 infections found in the different studies since the beginning of the pandemic is very variable (<1% in hospitals in the USA to about 20% in a British hospital). Mortality related to these nosocomial SARS-CoV2 infections is higher than in the general population. The risk factors identified for this nosocomial acquisition are multiple. We were confronted with nosocomial acquisitions and cluster situations in the services, without exhaustive data to measure these phenomena, and we lacked data to consider areas for improvement. The objectives of this study are to determine the proportion of nosocomial SARS COV 2 infections in the total number of patients hospitalized with a Covid-19 infection at the CHR Metz-Thionville in 2021, and to describe the characteristics of this population.
The current pilot study will recruit participants experiencing new, returning, or ongoing symptoms related to COVID-19 illness for at least four weeks after being first infected with SARS-CoV-2. All participants will attend a virtual 6-week course entitled Mindful Awareness Practices (MAPs) created, hosted and led by expert facilitators from the Mindful Awareness Research Center (MARC) at University of California Los Angeles (UCLA). This intervention will consist of a mix of lecture, practice, group feedback, and discussion regarding mindfulness. Mindfulness is the mental state achieved by focusing one's awareness on the present while acknowledging and accepting any feelings, thoughts, or bodily sensations. The research team will collect self-reported measures of mental health symptoms, physical health symptoms, and demographic information before and after participants attend MAPs. Objective health measures will also be collected by the research team including an active stand test, a 6-minute walk, and a blood sample.
Purpose: To determine the impact of SARS-CoV-2 infection and immunization on ovarian response to controlled ovarian stimulation (COS) and embryo development after in vitro fertilization (IVF) Methods: A retrospective multicentric cohort study of 427 oocyte donors was conducted between January 1st, 2018 and September 18th, 2022. Patients who recovered from SARS-CoV-2 infection, vaccinated or non-exposed were included. Demographic, cycle characteristics, and laboratory outcomes were compared.
By collecting the clinical data of hemodialysis patients with Omicron infection in RenJi Hospital from April 7, 2022 to June 10, 2022, the clinical characteristics of this population were analyzed. And to analyze the risk factors of different clinical outcomes according to the clinical outcome of this population.
