Filter by:This is an observational prospective study. The aim is to assess the prevalence of test positivity (swab or serological examination) to Coronavirus Disease-2019 (Covid-19) in relation to the duties and related occupational risk.
The primary objective of Part 1 (Single Ascending Dose) is to assess the safety and tolerability of anti-SARS-CoV-2 IgY when given as single-ascending doses administered intranasally to healthy participants. The primary objective of Part 2 (Multiple Dose) is to assess the safety and tolerability of anti-SARS-CoV-2 IgY when given as multiple doses administered intranasally to healthy participants. A secondary objective is to assess the pharmacokinetics of anti-SARS-CoV-2 IgY when given as multiple doses administered intranasally to healthy participants. Safety will be evaluated using adverse event (AE), physical examination (including vital signs), electrocardiogram, and clinical laboratory data. Pharmacokinetics will be evaluated by serum anti-SARS-CoV-2 IgY concentration.
This study is a randomized, double-blind, placebo -controlled IIb clinical trial, in order to evaluate the safety and immunogenicity of Recombinant Novel Coronavirus Vaccine (Adenovirus Type 5 Vector) in people 6 years old and above and .
This study will be conducted in 2 phases. Phase 1 of this study will be a single-centre, open label, dose escalation first in human (FIH) study conducted in 2 groups of healthy participants. Group 1 will enrol adults aged 18-55 years (inclusive); Group 2 will enroll elderly adults (elderly) aged 56-75 years (inclusive). Phase 2 of this study will be a single centre, the proposed design will be observer-blind, placebo-controlled study to assess the safety, reactogenicity, and immunogenicity of ChulaCov19 vaccine in healthy adults (18-75 years of age inclusive).
Patients on dialysis are at risk for several infectious diseases, since they have reduced immunological and have to regularly attend dialysis centres even if a pandemic is going on. Dialysis patients and healthcare professionals of dialysis centres can become infected one with the other. The incident risk of COVID-19 in dialysis centres is still unknown. Given the challenges of an early diagnosis of COVID-19, the likely transmission with outbreaks, the possibility of reciprocal transmission of the infection among patients and healthcare professionals, the frequent clinical severity of COVID-19 in dialysis patients because of the coexistence of several comorbidities, CONTACT TRACING could be an effective and efficient tool to contrast COVID-19 spreading in dialysis centres.
The primary goal of this project is to identify the best messaging and implementation strategies to maximize SARS-CoV-2 testing for children with intellectual and developmental disabilities (IDD) and their teachers to help ensure a safe school environment. Additionally, we will understand nationally the perceptions of COVID-19 and identify facilitators and barriers to help with the adoption of testing in other parts of the US and the necessary strategies to address other mitigation strategies including vaccination.
A randomized, double blind, placebo-controlled, phase 2 clinical trial to investigate the efficacy and safety of 2 doses of NuSepin® intravenous infusion in COVID-19 pneumonia patients
Patients with coronavirus disease (COVID-19) and pneumonitis often have hypoxemic respiratory failure and a need of supplementary oxygen. Guidelines recommend controlled oxygen, for most patients with a recommended interval of SpO2 between 92 and 96 %. We aimed to determine if closed-loop control of oxygen was feasible in patients with COVID-19 and could maintain SpO2 in the specified interval.
The purpose of this study is to investigate the clinical correlates of the effects of the COVID-19 pandemic on patients with Functional movement disorder (FMD) and Parkinson s Disease (PD). Primary objectives: To evaluate the change in neurological symptoms domain of the survey between pre and post-COVID 19 in FMD and PD patients. Secondary objectives: - To evaluate the change in total score of the survey between pre and post COVID 19 in FMD and PD patients - To evaluate the change in other symptom domains of the survey between pre and post COVID 19 in FMD and PD patients. Domains include: Mood/Energy, sleep, symptoms of abnormal movements related or unrelated to primary disease, physical health and exercise related change Exploratory objectives: - To evaluate whether there is a modifying effect of disease group in the changes in total score or symptom domains - To evaluate whether there is a relationship between disease severity and changes in total score or symptom domains - To evaluate whether there is a correlation between changes across symptom domains - To evaluate whether there is a correlation in raw score across symptom domains within each period Research Methods: Data will be solely collected through the use of online instruments via CiSTAR as a designed questionnaire. Questionnaire items A questionnaire aimed at determining the effects of the COVID 19 pandemic and subsequent isolation on functional state of patients with FMD and PD. The questionnaire items include: Items investigating Mood/Energy before and after COVID 19 out break Items investigating Sleep habits before and after COVID 19 out break Items investigating Neurological symptoms before and after COVID 19 out break Items investigating daily functioning before and after COVID 19 out break Items investigating Exercise habits before and after COVID 19 out break No questionnaire items will be actionable , which are items that would identify an imminent risk for participant safety requiring urgent and immediate medical or psychiatric
Background: COVID-19 is an infection caused by a coronavirus. It can affect different parts of the body. For most people, it causes fevers or trouble breathing. Some people can have symptoms long after they recover. Researchers want to learn if there are signs of changes in the nervous system that may be related to COVID-19. Objective: To test the nervous system (the brain and nerves) in people who have had COVID-19 yet still have certain symptoms even after recovering. Eligibility: People age 18 and older who had COVID-19 and still have neurologic symptoms after they recovered from the initial infection. Design: Participants will be screened with a medical record review. Participants will have a neurological exam. They will complete pen-and-paper tests of their memory and thinking. They will complete a smell test with 'scratch-and-sniff' booklets. They will give blood samples. Participants will have magnetic resonance imaging (MRI) of the brain. Soft padding or a coil will be placed around their head. They will lie on a table that slides in and out of the MRI scanner. They will get a contrast dye through an intravenous (IV) catheter. Participants blood pressure, blood flow, skin temperature, sweating, and breathing will be monitored. Participants will have an electrocardiogram to measure heart function. Participants will blow into a mouthpiece for several seconds. Participants will lie on a table that has a motor. The motor tilts the table. Participants will have blood drawn through an IV as the table tilts. Participants will have a lumbar puncture. A small needle will be inserted into the spinal canal to obtain fluid. Participants may repeat some tests 8 weeks to 1 year later.
