Filter by:This protocol describes the challenge non-typhoidal Salmonella (CHANTS) study. This is a first-in-human phase 1, double-blinded, randomised, dose-escalation human infection study, conducted in healthy volunteers aged 18 to 50 years. The primary objective of the study is to perform a dose escalation with two strains (ST19 or ST313) to determine the infectious dose required for 60-75% of volunteers to develop Salmonellosis using a composite diagnostic criterion. The secondary objectives of the study are to describe and compare the clinical and laboratory features following controlled human infection. It is hoped that the successful establishment of an NTS human challenge model can be used in the future to test candidate vaccines for NTS disease.
The goal of the research is to assess candidate COVID-19 rapid diagnostic tests (e.g. immunodiagnostic antibody tests, like Cellex qSARS-CoV-2 IgG/IgM Rapid Test, or antigen tests, like Turklab Test-It COVID-19 Home Test, AllBio Science Inc. and Artron Laboratories Inc. rapid COVID-19 antigen tests in order to judge their clinical accuracy compared to Centers for Disease Control (CDC)-recommended molecular genetic testing and clinical diagnosis. Second, it is our goal to determine if self-testing assisted by COVIDscanDX mobile device camera acquisition software platform and telemedicine clinical/technical support (virtual point-of-care) improves the ease of use and immediate interpretation of the tests, thus making self-testing comparable in accuracy and safety to testing in a clinical setting. Third, we are testing antibodies to SARS-CoV-2 after diagnosis with COVID-19 or following vaccination to measure the onset and time course of detectable antibodies from finger-stick blood drops and rapid antibody lateral flow tests. The overall purpose of the study is to dramatically increase the capacity of COVID-19 testing by establishing the safety, ease-of-use and validity of self-testing assisted by mobile device imaging and telemedicine remote support and provide evidence of antibody time-course response to vaccination.
PENGUIN is a pragmatic multi-center trial investigating the effects of pre-operative mouthwash and perioperative oxygen on the incidences of pneumonia and surgical site infection (SSI) following major abdominal surgery. Patients will be recruited from low and middle income countries and randomly assigned to a trial treatment arms: a) pre-operative chlorhexidine mouthwash and 80-100% FiO2; b) no pre-operative mouthwash and 80-100% fraction of inspired oxygen (FiO2); c) pre-operative chlorhexidine mouthwash and 21- 30% FiO2; or d) no pre-operative mouthwash and 21-30% FiO2.
To examine the impact of health determinants at the individual (e.g. health related behaviors) and societal level (e.g. environmental factors, health related policy, quality of health systems) on health outcomes (e.g. death, non-communicable disease development) across a range of socioeconomic and health resource settings. Additional components of this study will examine genetic factors for non-communicable diseases. This will be examined both through a cross sectional component, and prospectively (cohort component).
