Prospective Study of Persistent Dyspnea in Recovered COVID-19 Patients
Covid19DyspneaWe 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.
Dynamics of the Immune Response to COVID-19 / Infection by SARS-CoV-2

Fatigue and Sleep in Patients With COVID-19
Covid19Recent studies show that patients who have contracted COVID-19 retain very significant fatigue after resolving the infectious episode. This fatigue may be explained by low-grade inflammation. There is more data for patients with COVID-19 who have been hospitalized than for non-hospitalized patients with milder forms. However, COVID-19 related fatigue would not only affect elderly people with severe cardiopulmonary consequences but also young subjects without severities. This notion is not very widespread and to date, COVID contracted by young subjects is considered to have very few consequences on their health. It is also known that the prevalence of sleep debt is significant in the general population and particularly in young people, and it is also known that sleep deprivation increases low-grade inflammation and facilitates the risk of viral contamination. The association between sleep deprivation, drowsiness and possibly low-grade inflammation raise questions about the mechanisms of fatigue in the general population. Investigators are also entitled to wonder to what extent the chronic sleep debt suffered by the French population can explain an increased risk of contamination by COVID 19 but also significant residual fatigue after COVID infection. Bordeaux University Hospital screens 2,000 subjects per day at risk of being infected by COVID, it would be very interesting to measure, in a population of young adults aged 18-45 years, frequently exposed to a sleep debt, sleep hygiene (bedtime and wake-up times, sleep and wake-up schedules, and overall sleep satisfaction), average sleep duration, level of fatigue and drowsiness and to compare these thresholds between subjects with or without COVID 19 according to nasopharyngeal PCR.
Differences in Exhaled Breath by Using Ion Mobility Spectrometry (IMS) in Subjects Tested for SARS-CoV-2...
SARS (Severe Acute Respiratory Syndrome)Covid19Breath gas analysis is the evaluation of exhaled breath. It aims to evaluate the volatile organic compounds (VOCs) in exhaled breath. In this feasibility study it is intended to find specific peaks/pattern in exhaled breath indicating an infection with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2).
Long-term COVID-19 Immune Response in a Vulnerable Neighbourhood in Argentina
Coronavirus Disease 2019Between June 10t h and July 1st, a cross-sectional design study in an Argentina slum, showed a prevalence based on immunoglobuling G-class (IgG) antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) of 53.4%. It remains unanswered whether natural infection produces sustained antibodies. The aim of this study is to evaluate the presence of IgG antibodies for Coronavirus disease 2019 (COVID-19) after 5 months in inhabitants of Barrio 31 who consented the Seroprevalence Study for COVID-19.
Investigational Performance Evaluation of the Nanomix eLab® COVID-19 Rapid Antigen Panel With Samples...
Covid19Prospective samples will be collected to evaluate the agreement between a EUA RT-PCR test as the comparator method against the Nanomix eLab® system.
COVID-19 Impact on the Lombardy Region's Emergency System
Covid19This study has 3 main goals: to quantitavely describe the Covid-19 impact on the organization and functioning of the Lombardy's emergency system; to create statistical model able to predict the flow of patients to the emergency room during the epidemic period and their destination (ex: discharge, hospitalization, death); to value the impact on the non Covid-19 patients, both for their possibility to receive medical treatment and as an outcome on their health
CARTOON: CoronAviRus (COVID-19) educaTional prOgram fOr childreN
Covid19Pediatric Psychiatric Disorder1 moreOur study aims to investigate whether our CoronAviRus educaTional prOgram fOr children (CARTOON) facilitates the adherence to hygiene measures and is feasible to dispel fear in preschool children (3-6 years old) during the pandemic.
Detection of COVID-19 Decompensation
Covid19In this study we will be monitoring for patient events (emergency department admission, hospital admission, admission to an observation unit, or death) and evaluating the feasibility and utility of using pinpointIQ in the management of patients with COVID-19. Vital sign (physiology data) is collected to build a Covid Decompensation Index and contribute data to a Covid Digital Hub supported by the National Institutes of Health.
Prospective Determination of COVID-19 Infection Rate in a Chemotherapy Unit in Mexico.
Covid19Cancer1 moreCancer patients are considered vulnerable to COVID-19 infection. During the pandemic, cancer patients may need to continue their regular treatment of chemotherapy and / or radiotherapy and therefore must visit a hospital unit. As such, they may be at risk for SARS-CoV-2 infection by means of close contact to other patients and health care workers. Hospitals may implement policies to identify symptomatic subjects and limit their access to the chemotherapy / radiotherapy unit. However, asymptomatic COVID-19 positive patients may escape these filters and potentially be contagious to other patients and their health-related workers that care for other several patients. Therefore, there is a real risk of an outbreak that affects a particularly fragile patient population. Patients and their doctors need to know what is the risk associated to visiting a chemotherapy unit in order to decide if the risk outweighs the benefits of cancer treatment in their particular case. To date, this risk is unknown. The study will test patients and health care workers for COVID-19 infection during the peak of the pandemic in a chemotherapy unit in Mexico in order to determine this risk.
