Filter by:This is a single-blind, parallel-group, randomized pilot study designed to evaluate and compare the efficacy of 3 different mouthwashes containing 0.2% Chlorhexidine digluconate, 1.5% Hydroxide peroxide or Cetylpyridinium chloride in reducing Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load in the saliva of COVID-19 positive patients at different time-points. A convenient sample of up to 40 COVID-19 positive patients diagnosed via test and/or presenting COVID-19 clinical symptoms will be identified in the inpatients and/or outpatient clinics at the Newham University Hospital and at The Royal London Hospital, Barts Health National Health Service (NHS) Trust, United Kingdom (UK). The study will consist of one visit. Unstimulated saliva samples will be collected from all COVID-19 positive patients before and at 30 minutes, 1, 2, and 3 hours after mouth rinsing (Group 1-3 ) or no rinsing (Group 4). Viral load analysis of saliva samples in the different time-points will be then assessed by Reverse Transcription quantitative PCR (RT- qPCR).
This Phase III study will assess whether AZD7442 (a combination of 2 mAbs) can safely treat outpatient adults with COVID-19 and prevent either severe COVID-19 or death.
The management of the Grand Hôpital de Charleroi hospital authorized the performance of a serology for each member of the establishment's staff in order to better characterize the proportion of its employees who have already been in contact with the SARS CoV-2 virus for organizational and evaluation purposes symptoms.
To evaluate the prevention of SARS-COV-2 infection after administration of DWJ1248 in person who contact from COVID-19 confirmed patient compared to the placebo.
Preoperative antiseptic mouth rinses have been widely used as a standard protocol before routine dental treatment reduces oral microorganism counts. During dental procedures, aerosolized microorganisms contaminate the dental environment and nearby surfaces and remain suspended for 4 hours. Thus, the reduction in the number of aerosolized microorganisms by pre-procedural rinsing may reduce cross-contamination between dentists, office personnel, and patients. Recent reviews have advocated the use of preoperative rinsing to control and reduce the risk of SARS-CoV-2 transmission. However, no clinical studies have been done yet to support the effectiveness of any pre-procedural oral rinses against SARS-CoV-2. The proposed study will mitigate the spread of COVID-19 disease in dental healthcare facilities and ensure the patients' good health and healthcare workers. The purpose of this clinical trial is to compare the efficacy of four commercially available mouth rinses povidone-iodine (PVP-I), hydrogen peroxide (H2O2), cetylpyridinium chloride (CPC), sodium hypochlorite (NaOCl) on the salivary SARS-CoV-2 viral load at four-time points (baseline and 5-, 30-, and 60-min post rinsing) relative to two control groups (distilled water and no-rinse) in a cohort of positive COVID-19 patients.
Distinguishing changes on patients that have received thoracic radiotherapy and patients that are currently receiving or have recently received IO and presenting lung changes which will be identified using AI.
The study assesses the efficacy of early administration of hyperimmune plasma in covid-19 patients who are on CPAP or intubated. Efficacy is measured as a 2 point decrease in the WHO scale
This Lucira COVID-19 All-In-One Test Kit performance study will be used to establish the performance of the Lucira COVID-19 All-In-One Test Kit as compared to a known high sensitivity RT-PCR molecular assay. The results of this study will be used to demonstrate the Lucira COVID-19 'swab to result in 30 minutes' test kit is similar in performance to known high sensitivity best-in-class molecular assays performed in high complexity labs. The results of this study will be combined with other studies the Sponsor has underway and will support a FDA Emergency Use Authorization (EUA) of the Lucira COVID-19 All-In-One Test Kit. This performance study will include nasal swabs self-collected by study subjects at community-based locations with trained medical staff. A subject's participation in this study will consist of one study visit and one collection event. The subject self-collects a nasal swab sample according to Lucira COVID-19 Test Kit instructions and runs test according to Quick Reference Instructions (QRI). Following the Lucira COVID-19 All-In-One Test Kit self-collection will be an additional swab collection for reference method testing. One (1) additional NS specimen will be collected either by the health care professional or self-collection, prepared in Transport Medium and sent to a reference laboratory.
To evaluate if omalizumab is effective in decreasing mortality in severe hospitalized COVID-19 cases.
The current study will be a randomized controlled trial (RCT) investigating an adapted online Mindfulness-Based Stress Reduction (MBSR) program versus daily online self-help mindfulness exercises, in preventing incident/prevalent psychopathology in healthcare workers allocated to work with COVID-19 patients. Outcome measures include depression, anxiety, somatoform symptoms, post-traumatic stress, insomnia, substance abuse, post-traumatic growth and positive mental health. The study also aims to explore possible working mechanisms such as perseverative thinking, mindfulness skills and self-compassion. The study will have a follow-up duration of 7 months from baseline.
