Filter by:Background: Viral infections such as COVID-19 may lead to flare-ups in people with systemic autoimmune diseases (SAD). These infections may also change the function of their immune system and/or cause problems with their blood vessels. Researchers want to learn how people with SAD respond to treatments or vaccines for COVID-19. Objective: To understand how COVID-19 affects inflammation, the immune system, and blood vessels in adults and children with autoimmune diseases. Eligibility: People ages 15 and older who have been diagnosed with an autoimmune disease or are a healthy volunteer Design: Participants will have a screening visit. This will include: Medical history and physical exam EKG Chest x-ray COVID-19 test. A swab will be put in the participant s nose or the back of their mouth. Blood and urine tests Participants will be placed into 1 of 4 groups: 1. Those with previously documented COVID-19 infection or COVID vaccination 2. Those with a recently known COVID-19 exposure or vaccination 3. Those with no known COVID-19 exposure or vaccination 4. Those who developed an acute COVID-19 infection Depending on their group, participants will have 1 to 5 more visits. These will occur over 12 to 18 months. Visits may include: FDG PET/CT scan. Participants will lie in a doughnut-shaped machine. The machine creates pictures of the body. For the scan, they will have a radioactive substance injected into their arm through an IV. Kidney function tests Non-invasive vascular studies test. These tests are similar to what it feels like to have blood pressure checked.
This study is designed to compare the performance of the NOWDx COVID-19 Test to an emergency use authorized PCR test result. The intent is to show the rapid test device is comparable to a currently marketed device. The NOWDx COVID-19 Test is an in vitro lateral flow immunoassay intended for qualitative detection of total antibodies to SARS-CoV-2 in human whole blood (venous and fingerstick).
This study is a randomized, single-blinded, parallel, superiority, controlled trial. The main objective is to verify the effects of a telehealth stretching exercise program on pain, depression, sleep parameters and functionality of women with fibromyalgia, during the Covid-19 pandemic. Participants will be women with primary fibromyalgia, seen at public and private health services, in the city of Pelotas (south of Brazil). Participants will be recruited through social networks, newspapers and support from the National Association of Fibromyalgia and Correlated Diseases (Anfibro). Eligible participants will be randomized, stratified by age (30 to 45; 46 to 60), and allocated to one of the two groups, experimental or control. The experimental group will receive a telehealth stretching exercise program twice a week (guided by a professional) and counseling guide to stretching exercises with explanatory video regarding the execution of the protocol proposed by the guide. The total duration of exercise program will be 40 minutes (will be 12 exercise, 3 sets of each stretching for 10 seconds, carried out individually by a video call application - WhatsApp). The control group will receive only counseling guide to stretching exercises with explanatory video regarding the execution of the protocol. Both interventions will last 12 weeks, with outcomes evaluations in three moments: baseline (week 0), midpoint (week 6) and after the intervention (week 13). The following outcomes will be evaluated: generalized index of pain, fatigue and severity of symptoms, depression, level of physical activity, functionality, quality of life and sleep. All outcomes will be evaluated by questionnaires self-completed, that will be answered on Google Docs by video call, with exception of functional test that will be applied by video call. The study's hypothesis consists of improving outcomes for both groups, but with superiority for the experimental group.
This is an adaptive Phase I trial of a vaccine consisting of autologous dendritic cells previously loaded ex vivo with SARS-CoV-2 spike protein, with or without GM-CSF, to prevent COVID-19 in adults.
The study has a retrospective and a prospective component. The retrospective component aims to review data of all airway management related SAEs in COVID 19 patients (between April and July 2020); hypoxemia, hypotension and cardiac arrest within 15 min of intubation. The prospective component aims to assess the incidence of COVID-19 infection in Airway Management Team members by means of an interview assessing their COVID19 status after participating in airway management in the period outlined above. This prospective interview component is starting in December 2020.
Approximately 20% of patients hospitalized with COVID-19 require intensive care and possibly invasive mechanical ventilation (MV). Patient preferences with COVID-19 for MV may be different, because intubation for these patients is often prolonged (for several weeks), is administered in settings characterized by social isolation and is associated with very high average mortality rates. Supporting patients facing this decision requires providing an accurate forecast of their likely outcomes based on their individual characteristics. The investigators therefore aim to: 1. Develop 3 CPMs in each of 2 hospital systems (i.e., 6 distinct models) to predict: i) the need for MV in patients hospitalized with COVID-19; ii) mortality in patients receiving MV; iii) length of stay in the ICU. 2. Evaluate the geographic and temporal transportability of these models and examine updating approaches. 1. To evaluate geographic transportability, the investigators will apply the evaluation and updating framework developed (in the parent PCORI grant) to assess CPM validity and generalizability across the different datasets. 2. To evaluate temporal transportability, the investigators will examine both the main effect of calendar time and also examine calendar time as an effect modifier. 3. Engage stakeholders to facilitate best use of these CPMs in the care of patients with COVID-19.
This retrospective-prospective longitudinal observational study was designed to evaluate the role of bedside lung ultrasound per se and in association with hemogasanalysis parameters in predicting the severity of COVID-19 patients in the Emergency Departement (ED). Retrospective data regarding patients who presented at the ED of IRCCS San Raffaele Hospital from 10/11/2020, together with those acquired by the observation of patients who will access to the ED until 10/05/2021 will be collected, configuring a total enrollment period of 6 months. Clinical informations about patients' medical history will be recorded, with particular focus on the type and date of onset of the symptoms. The diagnostic and therapeutic strategy will be chosen according to the current standard of care. Results of bedside lung ultrasound, together with vital parameters, blood gas analysis, laboratory and other findings will be recorded. The primary outcome will be defined as patients' outcome at time of discharge from the ED, in terms of intensity of required care (home discharge, low or high-intensity care hospitalization, death). Secondary outcomes will be patients' prognosis 30 days after access to ED and the required intensity of care (eg need for non-invasive ventilation, oro-tracheal intubation).The follow-up 30 days after access to the ED will be evaluated by telephone survey or by consulting medical records.
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 purpose of this study is to characterize microvascular reactivity on the forearm muscle using non-invasive near-infrared spectroscopy in critically ill COVID-19 patients, and to correlate its alterations with 28-day mortality in ICU COVID-19 patients.
