Filter by:Fluorescence is one of the most commonly used research and detection techniques in the field of biomedical science. The characteristics of fluorescent probe directly affect the performance and application of fluorescence analysis and imaging. Aggregation-Caused Quenching has limited the application of traditional fluorescent probes to some extent. This project intends to systematically evaluate the detection efficiency of new methods through the detection of biomarkers in clinical samples and the comparison with the detection methods of traditional biomarkers, so as to provide theoretical and experimental basis for the establishment of fast and simple biomarker detection technologies with new biological probes.
This pilot study will evaluate study processes and feasibility of a future large-scale clinical trial that proposes to test whether low-risk children managed as outpatients with community-acquired pneumonia (CAP) and procalcitonin (PCT) levels <0.25 ng/mL treated with placebo have a similar clinical response to those treated with antibiotics and fewer adverse effects.
The two-part phases will each have a unique patient population, The goal in this application is to see if that carotid bodies are "offline" is correct and to determine whether a cohort of SARS-Cov-2 patients can be identified who fit this profile and would be suitable for drug treatment. The testing will require one group of subjects to hold their breaths for a short period while the investigators monitor vital signs and blood O2 levels. A second group of "healthier" COVID subjects will be asked perform a walk-test inside their rooms for six minutes while vital signs are monitored as well as blood O2 levels. If the subjects are in the healthy control group, they will perform the walk test in a designated hallway at the medical center also while there vitals are being monitored. The goal, using a mild stimulus, is to determine whether respiration increases if blood O2 saturation is decreased. If it does not, that would indicate a failure of the carotid body oxygen sensing system.
Surveys administered to subjects who have recovered from COVID-19 to assess how effective their treatment was.
This study uses a new breathing device called 'N-Tidal C' handset which measures breathing patterns. Investigators have found that people with cardiac and respiratory illnesses breathe out a gas, called carbon dioxide (CO2), in a different way to healthy people. The pattern of breathed out CO2 (the waveform) varies according to the underlying health of the user's lungs. Monitoring these changes may help doctors to more accurately diagnose and monitor the most common and serious respiratory conditions.
This project will use data obtained from a proprietary vision-based patient monitoring and management system (OxeVision) for measuring heart rate and respiratory rate which is in clinical use at the Coventry and Warwickshire Partnership NHS Trust.
The study will enroll up to 27,200 participants in order to demonstrate the efficacy of the active Ad26.RSV.preF-based study vaccine in the prevention of Reverse Transcription Polymerase Chain Reaction (RT-PCR) confirmed Respiratory Syncytial Virus (RSV)-mediated Lower Respiratory Tract Disease (LRTD) when compared to placebo in adults aged 60 years and above.
COVID-19 is respiratory disease caused by the severe acute respiratory coronavirus 2 (SARS-CoV-2), a novel coronavirus which has spread rapidly across the world with over 149.9 million laboratory confirmed cases and over 3.1 million reported deaths since December 2019. Approximately 4-8% of hospitalized patients with COVID-19 have co-infection with bacterial pathogens however there is widespread and often broad-spectrum antibiotic use in these patients. This is a prospective, multi-center, non-inferiority pragmatic clinical trial of antimicrobial stewardship prospective audit and feedback versus no antimicrobial stewardship intervention on physicians attending to patients with proven SARS-CoV-2 infection confirmed by nucleic acid testing in the preceding 2 weeks of hospitalization for acute COVID-19 pneumonia. Prospective audit and feedback is the real time review of antibacterial prescriptions and immediate feedback to prescribers to optimize antimicrobial prescriptions. Hospital beds will be stratified by COVID unit and critical care unit beds, and will be computer randomized in a 1:1 fashion into 2 arms (antimicrobial stewardship intervention versus no antimicrobial stewardship intervention) prior to study commencement at the participating site. Patients hospitalized to study-eligible beds will be followed for primary and secondary outcomes. The objective of this study is to determine the effect of an antimicrobial stewardship intervention (prospective audit and feedback) on clinical outcomes in patients hospitalized with acute COVID-19.
This study aims to validate dried blood spots (DBS) for SARS-CoV-2 (Severe Acute Respiratory Syndrome 2) antibody detection in elderly individuals.
The main objective of the proposed study is to evaluate the impact of coronavirus (2019-nCoV), hereafter COVID -19, on patients' loss of functional capacity after completion of hospital treatment. Specifically, the research will focus on examining changes in musculoskeletal, cardiovascular, and respiratory function, as well as motor control. In addition, we aim to evaluate rehabilitation treatments after recovery from COVID -19 and consider additional preventive measures based on previous experience.
