Filter by:We are using a tool called QtNGS to measure the abundance of local pathogens in patients with ventilator-associated lower respiratory tract infections. We hypothesize that changes in pathogen abundance before and after treatment are related to patient outcomes. This study aims to evaluate the effectiveness of the tool by analyzing the changes in pathogen abundance and exploring the relationship between these changes and clinical outcomes.
The clinical trial aimes to evaluate multiple large language models in respiratory disease consultations by comparing their performance to that of human doctors across three major medical consultation scenarios. The main question aims to answer are: - How do large language models perform in comparison to human doctors in diagnosing and consulting on respiratory diseases across various clinical scenarios? In three clinical scenarios including the online query section, the disease diagnosis section and the medical explanation section, research assistants or volunteers will be asked to cross-question all LLMs or real doctors using predefined online questions and their own issues. After each questioning session, a short washout period is implemented to eliminate potential biases.
The aim of this study was to compare the efficacy and safety of the essential oil-based product in patients with mild to moderate symptomatic COVID-19 Positive infection confirmed by PCR. A computational simulation approach of the molecular interaction (binding) of the main components of essential oils exhibiting antiviral activity with known intracellular protein targets of SARS-CoV-2 (nsp5: Main Protease) was adopted as a rationale for this study. SARS-CoV-2, a single-stranded RNA virus, has four major structural proteins Spike (S), Membrane (M), Envelope glycoprotein (E) and Nucleocapsid (N) protein and non-structural proteins (nsp). These non-structural proteins, of which there are 16 in total in the genome of the virus, play key roles in the mechanisms of the virus life cycle, including replication, transcription, protein synthesis and modification of RNA. Main protease (Main protease, Mpro, 3CLpro), virus Since they are directly involved in the maturation of these nsp proteins, which have an important role in many mechanisms of the life cycle, they have been the target enzyme in the development of new antiviral drugs for the treatment of COVID-19. In this study, our main rationale is to investigate the effect of essential oils on nsp5: Main Protease enzyme activations.
Prospective, observational multicentric study which aims at identifying lung POCUS (Point of Care UltraSound) findings associated with failure of noninvasive ICU-LRS (Intensive Care Unit Level Respiratory Support) (defined as escalation of settings or need for intubation and invasive mechanical ventilation) in infants requiring noninvasive ICU-LRS in the ICU for bronchiolitis and other LRTI (Low Respiratory Tract Infection) and at identifying lung, pleural, and diaphragm POCUS findings that are associated with a clinical improvement after escalation of ICU-LRS support by comparing POCUS findings from the first 24 hours of ICU stay to a subsequent study 1 day later.
Currently, there is a lack of evidence-based prevention strategies for respiratory infection and management of these conditions can be costly to the public. Airway nitric oxide provides a first line of defense against pathogens, and beetroot juice, a source of dietary nitrate, has been shown to elevate nitric oxide. The main objective of this project is to demonstrate that one week of supplementation with beetroot juice elevates airway nitric oxide during stressful periods in young adults and thereby can protect against respiratory viral infections.
Recurrent respiratory papillomatosis (RRP) is an orphan disease that affects approximately 20,000 people in the United States and is caused by infection with human papillomavirus (HPV) types 6 and 11. Since RRP is an orphan disease, it is an understudied disease entity with correspondingly few treatment options. The investigators hypothesize that by understanding the biology of RRP and the failed host immune responses against HPV, novel and rational therapies can be developed. This study will examine the genetic and immunologic alterations found in these rare tumors and distant metastatic involved sites (such as the lung) in patients diagnosed with RRP.
The primary objective of this effort will be to optimize and operationalize innovative passive surveillance systems and in parallel, the effort will identify, evaluate, and transition groundbreaking new technologies in diagnostics for operationalization. To meet the objective and execute the deliverables for this program of effort, the A&M Breathalyzer PROTECT Kiosk will be tested, modified and validated at Brooke Army Medical Center (BAMC). The collaborative efforts between the PI, Dr. Michael Morris at BAMC and Co-Investigator Dr. Tony Yuan at USU- Center for Biotechnology (4D Bio3) will assess the passive detection technology and provide a capability survey of use-case scenarios for different operational settings. Goals: 1. Optimization and operationalize the A&M Breathalyzer PROTECT Kiosk, portable mass spectrometer (MS) Detector for Deployment in Military Operational Medicine Environments. The Breathalyzer will be deployed to BAMC to test its detection capabilities of COVID-19 among symptomatic and asymptomatic COVID-19 carrier vs. those not infected compared to gold standard RT-PCR. 2. Evaluate the passive sensing, breath capture system, built within the A&M Breathalyzer PROTECT Kiosk. The conversion of the active breath capture system, currently requires a straw that the subject breaths into, where then a series of sensors built in the Breathalyzer would automatically sample the exhaled breath within proximity for recent COVID-19 exposure. This task would conclude with a set of sensors and sensor inputs that would be analyzed by the Atomic AI platform built in the device. Field testing at BAMC is planned to determine the level of detection and discrimination for sensor combinations to SARS-CoV2 components and biomarkers detected. This testing would update the Atomic AI algorithm, within the device, to understand the accuracy of positive detection and the resulting sensitivities.
To establish the relative accuracy of the LIAISON® NES Flu A/B, RSV & COVID-19 assay for viral nucleic acid targets from professionally collected or patient self-collected dry nasal (NS) swabs and to establish the relative accuracy of the LIAISON PLEX® RSP Flex assay from NS and nasopharyngeal swabs (NPS) in applicable transport media from human patients exhibiting clinical signs and symptoms of a respiratory tract infection.
Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities that is associated with altered commensal microbiota and a rising burden of immunological disorders among urban children. The investigators will estimate how rewilding of kindergarten yards affects commensal microbiome, prevalence of allergies, asthma, atopic dermatitis and infections, cortisol levels, cognitive skills and plasma cytokine levels of children. Our specific aims are: To assess if rewilding diversifies health-associated skin, saliva and gut microbiota and reduces infectious diseases and atopic or allergic symptoms. Assess whether the rewilding has positive effects on cognitive skills. Assess whether the rewilding changes cortisol and plasma cytokine levels. The investigators will recruit altogether 320 (160 per treatment) study subjects aged between 1-5 to questionnaire study (Task 2), from which 120 study subjects will be analyzed more detailed using microbiological and blood samples (Task 1).
The objective of our study is therefore to study the evolution of the respiratory microbiome of hospitalized newborns, its interaction with viral infections and their impacts on the evolution of newborns.
