Filter by:The use of personal protective equipment is mandatory for healthcare workers caring patient with COVID-19. To maximise the reduction of virus spread during clinical procedures involving the presence of healthcare workers, it is also recommended to patients to wear surgical facemask. Routine clinical procedures include cardio-pulmonary and strengthening exercises. During these exercises, the wearing of a face mask may be difficult to tolerate by patients, especially since they experience breathing difficulties due to the illness. Therefore, this study aims to verify the effects of the surgical facemask on breathing difficulties and exercise performance during a 1-minute sit to stand test.
We conducted a national, single center (Hospital Clínico Universitario de Valladolid, Spain, Valladolid), prospective study of patients with prior hospitalization because of COVID-19 who were admitted between March 1st, 2020, and May 15th, 2020. All eligible patients underwent at least at first-time follow-up from the index event. Exclusion criteria were age < 18 years old, pregnant women, terminally ill patients, active SARS-CoV-2 infections, inability to exercise and previous known severe pulmonary or heart disease. Patients underwent a clinical assessment for symptom burden, questionnaire for quality of life (Kansas City Cardiomyopathy Questionnaire and SF-36), venous blood sampling, 6-minute walking test (6-MWT), tests of lung function (spirometry and diffusing capacity of the lungs for carbon monoxide) and treadmill cardio-pulmonary exercise testing (CPET). 48-hours before the test of lung function and the CPET, all patients yielded a negative result in the reverse transcription-polymerase chain reaction (RT-PCR) for SARS-CoV-2. For definitive analysis patients were assigned to the control group if they did not refer dyspnea at the time of the follow-up, a small asymptomatic out-patient control group without prior hospitalization was also included.
The covid-19 pandemic started to spread worldwide since December 2019. It promoted to an exaggerated psychological stress and anxiety in humans due to the intolerable symptoms higher than usual death of many infected patients. This study examines the corona related anxiety and if there is need for drug intervention to treat this anxiety. To answer these questions, a survey made to the hospitalized patients including sex, age, educational level, Marital state, and a standardized questionnaires (GAD-7 and PHQ-9) which has been validated and shown to possess good psychometric qualities in studies of participants from multiple populations.
This project aims to investigate the sensitivity and specificity of the rapid antigen test compared to RT-PCR test performed on samples from the nasopharynx and the anterior nasal cavity and the oropharynx, respectively.
A retrospective cohort study will be conducted using a large administrative database of U.S. hospitals to understand the volume-outcome relationship among patients hospitalized with COVID-19.
The purpose of the study is to assess safety and immunogenicity of heterologous booster vaccine containing combination of AZD1222 and rAd26-S (one of components of Gam-COVID-Vac vaccine) in adult subjects aged ≥ 18 years old to prevent COVID-19 spread.
The overarching objective for this prospective cohort study of COVID-19 in adolescents is to study the long-term effects, with particular emphasis on post-infectious chronic fatigue. A total of 500 individuals with a SARS-CoV-2 positive test will be enrolled in the acute phase of COVID-19 and followed for 6 months. A total of 100 individuals with SARS-CoV-2 negative test will be included during the same time period as a control group. Investigations include autonomic, pulmonary and cognitive assessement; a questionnaire charting symptoms, emotionality, personality, loneliness, life events and demographics; and extensive biobanking including genetic markers, viable PBMC, urine, feces and hair. A subgroup of 40 SARS-CoV-2 positive and 20 SARS-CoV-2 negative individuals will also undergo detailed cardiological examination by echocardiography. Primary endpoints are fatigue at 6 months as assessed by the Chalder Fatigue Scale and post-COVID-19 syndrome cases at 6 months according to the WHO definition
The primary aim of this study is to examine whether lower-risk activities displace participation in higher-risk behaviors during COVID-19. Investigators will test this aim by promoting specific activities that are expected to be low-risk when it comes to COVID-19 transmission (e.g., participating in a hiking challenge) and assessing impacts on participants' activity choices. Investigators also aim to describe adults' activity participation during COVID-19 generally and to examine secondary outcomes, including reported stress and sleep.
COVID-19 pandemic is currently affecting the globe. To date, there is no effective oral therapy against SARS-CoV2 infection. The investigators propose to test as a repurposing drug combination, a short course of tenofovir disoproxil and emtricitabine (TDF/FTC), as a proof-of-concept randomized open-label study to test its viral efficacy against SARS-CoV2.
In the course of Coronavirus Disease-19 (COVID-19) uncontrolled inflammation has been related to disease severity and unfavorable outcomes. Here, the investigators study the longitudinal changes of pro- and anti-inflammatory markers in a population of patients undergoing maintenance hemodialysis (HD) affected by COVID-19, evaluating the potential modulating effects of two different dialysis approaches
