Filter by:Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.
The purpose of this research study is to find out how well two different 2023-2024 updated COVID-19 vaccines protect people from COVID-19 (the disease caused by the SARS-CoV-2 virus), and to determine if getting a 2023-2024 updated vaccine provides better protection from COVID-19 than not getting a vaccine. If the participant chooses to get a 2023-2024 updated COVID-19 vaccine as part of this study, they will have a 50/50 chance of receiving either the Novavax or Pfizer mRNA vaccine. If the participant decides not to get a 2023-2024 updated COVID-19 vaccine, the participant can still participate in other study activities. STUDY ACTIVITIES: - An online enrollment survey - An in-person enrollment visit - Weekly online surveys for 20 weeks - Weekly COVID-19 tests for 20 weeks - Additional online surveys if you have COVID-19 symptoms or tested positive for COVID-19. - Additional COVID-19 tests if you have COVID-19 symptoms or tested positive. - Online survey questions in the middle and at the end of the study
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.
Rhinitis, or inflammation of the nasal mucosa, can present with nasal obstruction, nasal discharge, itch or sneezing. If the sinusal mucosa is involved as well, it is called rhinosinusitis and facial pain or loss of smell is possible. Several causes are known, such as an underlying allergy ("allergic rhinitis", AR). If at least 2 symptoms are present for at least 12 weeks, it is called "chronic rhinosinusitis" (CRS). Up to 2/3 of the AR and CRS patients have symptoms upon exposure to triggers such as sudden temperature changes, smoke, fragrances… a phenomenon called "nasal hyperreactivity" (NHR). It is currently not clear why some patients suffer NHR while others do not. In this study, the investigators want to determine the prevalence and severity of nasal hyperreactivity in patients with chronic upper airway inflammation. To this end, patients and healthy controls will be asked to fill out a questionnaire inquiring presence and severity of nasal symptoms upon exposure to particular environmental triggers.
Vaccines work by stimulating the body to produce a high-quality, rapid and specific immune response upon exposure to infection by a particular disease-causing microorganism - the microorganism targeted by the vaccine. Evidence is emerging that some vaccines may have additional 'non-specific effects' (NSEs); that is, effects on the immune system beyond the direct protection against the diseases for which the vaccines were developed. It has been proposed that rabies vaccine has protective NSEs in people and animals, with receipt of rabies vaccine in children associated with a reduced risk of meningitis and cerebral malaria in one study, and a history of rabies vaccination in free-roaming dogs associated with increased survival rates in another study. Studies in mice have shown that prior rabies vaccination protects against bacterial sepsis. The biological mechanism of action of any such NSE of rabies vaccine is unknown. Other vaccines with reported protective NSEs (e.g. bacillus Calmette-Guerin vaccine against tuberculosis, a disease caused by Mycobacterium tuberculosis) have been show to reprogram the immune system, leading to enhanced protection against infection with disease-causing microorganisms unrelated to M. tuberculosis. In this study, we will test the hypothesis that rabies vaccine has non-specific protective effects against common infectious disease (CID) syndromes (upper respiratory illness, diarrhea and fever) in a population of veterinary students. We will randomly assign previously-unvaccinated students who volunteer for the study to receive a primary course of three injections of rabies vaccine (experimental group) or an identical course of three injections of sterile water (control group). Participants will not know to which group they have been assigned. We will ask all participants to report episodes of illness through an online survey each week for 26 weeks, and will also record all clinically- and laboratory-confirmed cases of illness with CID syndromes. We hypothesize that rates of self-reported new episodes of CID illness over 26 weeks will be at least 25% lower in the experimental group, relative to the control group.
The purpose of this prospective study is to evaluate the efficacy of the ResAppDx software application in the diagnosis of childhood acute respiratory disease, including pneumonia, bronchiolitis, asthma/reactive airways disease, croup, lower respiratory tract disease (LRTD), viral lower respiratory tract infection (vLRTI), and upper respiratory tract disease (URTD).
