Filter by:Randomized, double-blind prospective trial to test the efficacy of therapeutic, antiseptic mouth rinses to inactivate severe acute respiratory syndrome coronavirus (SARS-CoV-2) in saliva of COVID-19 positive patients aged 18-65 years old. All mouthrinses are commercially available and will be used according to on-label instructions. Patients will be randomized to a mouthrinse and will be asked to give a saliva sample immediately before and after a one minute mouthwash. Saliva samples will be collected from patients at 15 minute intervals thereafter up to an hour (15, 30, 45 and 60 minutes). The samples will be stored and used for real-time reverse transcription polymerase chain reaction (RT-PCR) detection of viral SARS-CoV-2 RNA and viral infectivity assays. Patients will also complete a short-survey on the taste and experience of using the mouthwash. This study involves 150 subject participants and one, 75-90 minute visit.
The aim of this study was to evaluate the efficacy and safety of high-dose dual therapy compared with furazolidone-based quadruple therapy as a rescue treatment for helicobacter pylori infection.
The aim of this study is to determine the efficacy of an oral nutraceutical with probiotics in restore vaginal health.
This study aims to investigate the epidemiology of SARS-CoV-2 infection among: i) HCW who triage patients with suspected SARS-CoV-2 infection and provide care to COVID-19 patients; and ii) laboratory personnel who test clinical samples for SARS-CoV-2 infection. After the second wave of the pandemic enrolment will be widen to any person working at the study hospitals.
Background and aims: Patients with severe Coronavirus Disease 2019 (COVID-19) are prone to secondary bacterial pneumonia. The use of probiotics against oral pathogens might prevent lung colonization and progression to bacterial pneumonia. This study aimed to assess the effect of Streptococcus salivarius K12 combined with Lactobacillus brevis CD2 in preventing secondary bacterial pneumonia in patients with severe COVID-19. Methods: This randomized placebo-controlled phase 2 trial involved 70 patients with severe COVID-19 admitted to the intensive care unit (ICU). Patients were randomly assigned to a 7-day course of oral gel containing Streptococcus salivarius K12 2 billion colony-forming units (CFU) and Lactobacillus brevis CD2 4 billion CFU every 8 hours or placebo, starting in the first ICU day. The primary outcome was bacterial pneumonia, established according to clinical, laboratory, radiological, and microbiological findings, whereas secondary outcomes were ICU stay in days and hospital mortality.
A Randomized, Double Blind, Placebo-Controlled Study to Evaluate the Effect of Nicotinamide Mononucleotide (NMN) As an Adjuvant to Standard of Care (SOC) On Fatigue Associated with COVID-19 Infection
This observational study evaluates whether lung sound analysis with LungPass device can be used to differentiate upper and lower respiratory tract infections (URTI and LRTI)
Diabetic foot ulcers (DFU) are one of the most common reasons for hospitalization of diabetic patients and frequently results in amputation of lower limbs. Of the one million people who undergo non-traumatic leg amputations annually worldwide, 75% are performed on people who have type 2 diabetes (T2DM). The risk of death at 10 years for a diabetic with DFU is twice as high as the risk for a patient without a DFU. The rate of amputation in patients with DFU is 38.4%4. Infection is a common (>50%) complication of DFU. Emerging evidence underscores the significant risk that biofilm infection poses to the non-healing DFU. Biofilms are estimated to account for 60% of chronic wound infections. In the biofilm form, bacteria are in a dormant metabolic state. Thus, standard clinical techniques like the colony forming unit (CFU) assay to detect infection may not detect biofilm infection. Thus, biofilm infection may be viewed as a silent maleficent threat in wound care.
The main goal of this study is to characterize the adaptive immune responses to SARS-CoV-2 infection in a cohort of children with cancer and impaired immune responsiveness and prolonged viral shedding of SARS-CoV-2, and to identify SARS-CoV-2 variants that might arise during poorly controlled virus replication
Emerging clinical details of the current SARS-CoV-2 pandemic have illustrated that there are multiple clinical presentations and outcomes of this viral infection. People with an infection have been reported to have a spectrum of disease from severe acute respiratory distress requiring ventilation, to mild respiratory or gastrointestinal symptoms and asymptomatic presentations. The SARS-CoV-2 pandemic has been accompanied with a substantial increase in the number of individuals presenting with new onset type 1 diabetes [1]. Most individuals presenting with type 1 diabetes since the start of the COVID-19 pandemic are SARS-CoV-2 antibody positive. These findings suggest that SARS-CoV-2 infection can cause type 1 diabetes. Investigators have identified that many individuals presenting with type 1 diabetes since the start of the COVID-19 pandemic are SARS-CoV-2 positive by swab or blood test. Researchers have also observed that T cells in patients who have had COVID recognise some of the peptides in the pancreatic islet cells, which are responsible for production of insulin. These findings suggest that SARS-CoV-2 infection may be associated with new onset of type 1 diabetes. The aim of this project is to understand the host immune response to infection with SARS-CoV-2 over time in convalescent newly diagnosed patients with type 1 diabetes, including acquired immune responses, gene expression profiling in peripheral blood and to identify host genetic variants associated with disease progressions or severity. Participants will have Type 1 diabetes and will have had a diagnosis of COVID-19 (confirmed by a positive nasopharyngeal swab PCR test and/or SARS-CoV-2 antibody test) and have recovered from COVID-19. Samples will be processed and analysed to explore the molecular mechanisms by which SARS-CoV-2 infection might precipitate immune attack on insulin-producing cells resulting in autoimmune diabetes.
