Data on COVID-19 in children are still scarce, and their role in SARS-CoV-2 transmission is poorly described. Furthermore, documentation of the best SARS-CoV-2 sampling methods in children are limited. In adults, saliva seems like a promising specimen to collect by noninvasive procedure to diagnose and monitor viral load of SARS-CoV-2, but this has not been tested in children yet. We want to test the following hypothesis: 1. Shedding load and duration of SARS-CoV-2 in children are related to age, gender, clinical symptoms and exposure 2. Salvia samples have equal or higher sensibility than nasal swaps in children for detection of SARS-CoV-2 3. Parental home testing of saliva and feces is feasible in children The study is a prospective cohort study of SARS-CoV-2 PCR-positive children from two test centers in the Capital Region of Denmark. Children aged 0-17 years with a PCR-positive SARS-CoV-2 test from a nasal or pharyngeal swab is included from May 2020 to January 2021 and followed-up for a period of 28 days with weekly sample collection and questionnaires. Samples include a saliva sample, a nasal swap and a rectal swap for children under four years of age. A semiquantitative RT-PCR method, will identify positive and negative samples and provide a Ct value estimating viral load. Saliva and fecal samples will be analyzed from November 2020-February 2021. Shedding duration will be related to medial history, clinical presentation, exposure, gender and age.
The main objective of the study is to evaluate the capacity of a novel nutritional supplement intervention including strains from the species Bifidobacterium longum, Bifidobacterium animalis subsp. Lactis and Lactobacillus rhamnosus, plus vitamin D, zinc and seleniumt) (immune system enhancer, antioxidant and anti-inflammatory capacity) to decrease the viral load by nasopharyngeal smear in patients admitted for COVID-19 coronavirus disease.
Covid-19 (English acronym meaning coronavirus disease 2019) is an emerging infectious disease caused by a strain of coronavirus called SARS-CoV-2. The current pandemic has resulted in a significant number of admissions in the emergency room (ER) due to suspicion of COVID-19 infection. Use of lung ultrasound is standard practice to diagnose acute respiratory failure in ER. Recently, typical lung ultrasonographic characteristics of COVID-19 disease has been described. The investigators demonstrated that the association of 4 signs in pulmonary ultrasound associated with a clinical sign (COVILUS score) could predict the occurrence of a positive RT-PCR in patients suspected of COVID-19 infection admitted to the emergency room. The investigators are going to conduct a new study to validate this COVILUS score in this type of patient. The main objective will be to validate the diagnostic performance of lung ultrasound in patients admitted to the emergency room with suspected COVID19 infection.
This study investigates whether donors with previous exposure to COVID-19 can pass their immunity by hematopoietic (blood) stem cell transplant (HCT) donation to patients that have not been exposed. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus that causes the COVID19 infection. This study may provide critical information for medical decision-making and possible immunotherapy interventions in immunocompromised transplant recipients, who are at high risk for COVID19 severe illness.
This is a Phase 1/2a clinical trial to assess the safety and immunogenicity of AdCLD-CoV19 in healthy adults.
The investigators aim to develop expert consensus statements on infection control management of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in intensive care units (ICU).
The COVID-19 outbreak leads to optimize the pathway in emergency departments. The length of time spent in the Emergency Department is linked to the morbi-mortality and the risk of COVID-19 transmission. The Amiens-Picardy University Hospital has developed an application (3P-U) that optimizes patient flow. It identifies the need of hospitalization and problems on the care path. Patients are categorized in high risk or not high probabilty of hospitalization. The main goal of this project is to evaluate the impact on the patient flow of the 3P-U application. Early lookup of bed for high probability hospitalization should be linked to a reduced time of length. This study will compare the time of length between this both groups.
Background: Some people who have had COVID-19 experience changes in the eye. Sometimes these changes are subtle and may not affect vision. Researchers want to learn how many people experience these eye changes and where in the eye they occur to better understand the outcomes of COVID-19 and its treatments. Objective: To examine possible changes in the eye that might have occurred as a result of COVID-19. Eligibility: Adults age 18 and older who were diagnosed with COVID-19 and recovered. Design: Participants will be screened with a medical history and physical exam. They will have blood tests. Participants will have an eye exam. Their pupils will be dilated with eye drops. Eye pressure and movements will be measured. Participants will have optical coherence tomography. Pictures will be taken of the retina and the inside of the eyes. Participants may have fluorescein angiography and indocyanine green angiography. They will be given a dye through an intravenous line. The dye will travel up to the blood vessels in their eyes. Pictures will be taken of the dye as it flows through the blood vessels. Participants may have electroretinography to test the retina. They will sit in the dark with their eyes patched for 30 minutes. Then they will watch flashing lights while wearing contact lenses that sense signals from the retina. Participants may have adaptive optics-assisted imaging. They will look at a specific location while images are taken of the retina. During the study, participants will have blood drawn through a needle in their arm. Fluid or tissue from the eye may be obtained if participants have a medically needed procedure. Participation will last for 12 months.
In this study, COVID-19 positive patients will be added to a bidirectional texting program to receive daily surveys about their symptoms with the infection. This data will further the understanding of COVID-19 symptom development throughout the infection period, as well as how those symptoms vary at different points of the day. This study will be a single cohort, observational study of COVID-19 patients.
