The goal of this clinical trial is to learn about exercise in veterans with new respiratory symptoms after deployment to Southwest Asia. The main questions it aims to answer are: 1. Do veterans with new respiratory symptoms after deployment have heart or lung abnormalities that contribute to difficulty exercising? 2. Does high-intensity interval training (HIIT) improve fitness and symptoms? Study participants will complete the following: 1. Study Visits 1A and 1B: Exercise test (VO2max test), echocardiogram (heart ultrasound), blood tests, questionnaires 2. Exercise program: 12 weeks of 3x/week supervised HIIT on upright stationary bicycle (\~40 minutes each) and 3x/week home aerobic exercise (45 minutes each) 3. Study Visits 2A and 2B: Exercise test (VO2max test), echocardiogram (heart ultrasound), blood tests, questionnaires
The overall aim of the study is to determine the clinical efficacy and mechanisms of action of anti-IL-4a (dupilumab) as treatment for patients with Aspirin-Exacerbated Respiratory Disease (AERD).
The investigators will assess the antibody, T cell and B cell responses to SARS-CoV-2 vaccination before and every 3 months for 18 months after the initial vaccination or subsequent vaccinations (boosters) in adults and children including patients with chronic medical conditions.
Background: The COVID-19 outbreak has strained the health care system. New tools are needed for diagnostic testing and monitoring of people who have the virus. Researchers want to test a device they hope can screen, detect, and monitor symptoms linked to respiratory diseases like COVID-19. Objective: To evaluate and validate a device that measures breathing, body temperature, heart rate, and tissue oxygenation. Eligibility: Healthy adults ages 18 and older with no flu-like symptoms and no current signs of infection, cough, fever, or sneezing. Design: Participants will have a physical exam. Their vital signs will be taken. Participants will sit in a chair. They will be monitored for 60 to 80 minutes while they do the following tasks: Rest for 10 minutes. They will repeat this after each task. Hold their breath for up to 2 minutes and then rest for 2 minutes. They will do this task 3 times. Pace-breathe with breathing rates of 10, 20, and 30 breaths per minute. They will do this task 2 times. Breathe air that has 5% of carbon dioxide for 5 minutes. During these tasks, data will be collected and recorded with a pulse oximeter, thermometer, respiratory belt, and spirometer. Participants will fill out questionnaires related to their daily activity (medication intake, exercise, smoking, and drinking). Participation will last for 2 to 3 hours.
This study is being conducted in two parts, A and B. Part A is a randomized, double-blind, parallel arm study to evaluate the safety and efficacy of LYT-100 compared to placebo in adults with post-acute COVID-19 respiratory complications. Part B is an Open Label Extension (OLE) study for patients who complete Part A.
Aspirin Exacerbated Respiratory Disease (AERD) is a relatively homogeneous disease characterized by adult-onset severe asthma, development of non-cancerous growths in the nasal canal (i.e. nasal polyps) and aspirin allergy. The cause of AERD is unknown, although likely results from environmental insults in combination with genetic susceptibility. AERD disease homogeneity increases the possibility of discovering narrowly-defined genetic contributors, and makes it an ideal population to study the genetic and epigenetic changes that cause asthma. Researchers recently discovered that gene expression of epithelial growth and repair (EGR) genes are substantially decreased in bronchial airway epithelial cells of severe asthmatics compared to less severe asthmatics and healthy controls. This new finding indicates that epithelial integrity and related processes may be of primary importance to the development of severe asthma, and potentially the severe asthma subtype, AERD. This finding was later supported in a subsequent lab model, which showed that blocking a central epithelial repair and differentiation gene, human epidermal growth factor receptor 2 (ERBB2), decreased healing time of bronchial epithelial cells after injury. Thus, the objective of the proposed study is to determine whether EGR gene are also down-regulated in AERD, a homogeneous severe asthma subtype. As an extension, the researchers will also determine whether genetic mutations and/or epigenetic changes relate to and potentially explain this down-regulation of EGR genes. Specifically, the researchers plan to obtain gene expression of freshly brushed nasal airway epithelial cells of 140 AERD patients, 70 non-aspirin sensitive asthma patients, and 35 healthy controls, noting that nasal epithelial gene expression has recently been shown to mirror lung epithelial changes in asthmatic airways. Swabbing the nasal canal for epithelial cells allows to evaluate airway epithelial cell gene expression non-invasively. Our experimental design contrasts AERD gene expression profiles against healthy controls, and determines whether EGR genes are depressed in AERD relative to health controls. As a corollary, the researchers look to discover an AERD-specific gene expression profile which may one-day aid in diagnosis and expand current knowledge of disease mechanisms. As an extension, the researchers will correlate gene expression changes, specifically any finding of down-regulated EGR genes, with methylation changes (i.e. epigenetic changes) and genetic mutations.
This study will test the accuracy of an investigational, non-invasive device for measuring heart rate and respiratory rate. The device emits radiowaves that allows it to pick up subtle changes in a person's chest wall, which allows it to calculate the heart rate and respiratory rate. We propose to study whether the device's measurements are accurate and reproducible in patients with chronic obstructive pulmonary disease (COPD) or asthma. The device undergoing study has been evaluated in healthy volunteers, but its accuracy in vital sign monitoring in patients with respiratory conditions has not yet been established. This study will serve as the foundation for additional work to assess the device's accuracy in measuring a patient's overall "work of breathing" or respiratory effort. Future work will examine the device's accuracy in measuring work of breathing in patients having an exacerbation of their underlying respiratory condition. The primary aim of this study will be to assess the validity of heart rate and respiratory rate measurements in patients with either COPD or asthma.
The present study is a prospective, single cohort study involving patients on narcotic medications, undergoing overnight sleep studies in the clinical sleep laboratory. The main hypothesis for the study is that the the frequency of sleep respiratory events (including central apneas) identified by a home sleep apnea test (HSAT) device (WatchPAT200U (wp200U) with centrals; Itamar Medical Ltd.) will significantly correlate with in-lab polysomnography (gold standard).
Subjects with physician-diagnosed aspirin-exacerbated respiratory disease (AERD) who remain unacceptably symptomatic with a SNOT 22 score \> 18 despite routine medical therapy will be enrolled in this single center, single-blinded study assessing the efficacy of dupilumab in AERD.
The overall aim of the study is to determine the efficacy of oral ifetroban, a novel antagonist of T prostanoid (TP) receptors, as a treatment for patients with aspirin-exacerbated respiratory disease (AERD).
The purpose of this phase 2 study is to assess the safety and efficacy of oral ifetroban for the treatment of aspirin-exacerbated respiratory disease (AERD). AERD is a disease that involves asthma, recurring nasal polyps, and respiratory reactions to aspirin and other nonsteroidal anti-inflammatory drugs.
The objective of this study is to look at the effects of distractive auditory stimuli (DAS) on reducing dyspnea intensity and related anxiety and increasing exercise tolerance. Investigators hope that compared to a no-music control condition, that under a music condition participants with COPD will (a) demonstrate increased self-paced walk distance and enjoyment; (b) have less dyspnea intensity, (c) experience less dyspnea anxiety; (d) have less fatigue and state anxiety; and (e) higher maximum heart rate. The upbeat music with a tempo of 90 - 100 bpm (an average-to-moderate walking tempo) is expected to have distractive and performance enhancing effects in order to increase tolerance to dyspnea and exercise. The long-term goal of this study is to increase physical activity in adults with COPD and RLD by promoting dyspnea and fatigue management through use of distractive auditory stimuli in the form of music.
The primary objective of the study is to determine the safety of oral ifetroban compared to placebo as measured by a \> 20% decrease in FEV1 compared to baseline following a dose of Investigational Medicinal Product (IMP) (Study Day 1 or 2) prior to initiation of the aspirin challenge.
The purpose of this trial is to test the hypothesis that a treatment diet low in omega-6 fatty acids and high in omega-3 fatty acids can cause improvement in asthma symptoms, nasal symptoms, and pulmonary function in patients with aspirin-exacerbated respiratory disease (AERD).
We hypothesize that the miRNA expression in subjects with nasal polyps and Aspirin-exacerbated respiratory disease (AERD) differs from the miRNA expressed in subjects with nasal polyps but without Aspirin-exacerbated respiratory disease (AERD).
The investigators are doing this research study to find out if giving a drug called prasugrel, which is used to prevent blood clots, can reduce reactions to aspirin in people with aspirin exacerbated respiratory disease (AERD), and to learn why taking aspirin every day can work as a treatment for people with AERD. People with AERD have symptoms of asthma, severe runny nose, polyps in the nose, and develop allergic reactions if they take medications like aspirin. People with AERD can be desensitized to aspirin in order to be able to safely use it daily, but the investigators do not know if prasugrel may prevent reactions to aspirin and provide a safer way for people with AERD to tolerate aspirin. The investigators also want to understand what is different about the cells and urine from subjects who have AERD, in comparison to subjects who have asthma but do not have AERD and subjects who have allergic rhinitis but do not have asthma. Lastly, the investigators want to understand how aspirin acts differently in subjects who have AERD, in comparison to subjects who have asthma but do not have AERD.
The aim of this study is to reduce the number of subsequent hospital admissions and/or emergency department (ED) visits for hospitalized patients with chronic obstructive pulmonary disease (COPD) by utilizing a respiratory care practitioner-led disease management (RCP-DM) program compared to standard discharge instructions and planning.
To diagnose aspirin hypersensitivity in asthmatics by using and safe, low-dose aspirin oral challenge. Hypothesis 1: A low dose of oral ASA (20 or 40 mg) will induce significantly different concentrations of arachidonic acid metabolites in ASA-sensitive asthmatics as compared to ASA-tolerant asthmatics. Hypothesis 2: The low dose (20 or 40 mg) ASA challenge will be well tolerated by ASA-sensitive asthmatics.
The purpose of this study is to identify biological markers of disease in patients with acute lung injury (ALI) that are predictive of either disease susceptibility or prognosis, or that identify novel targets of therapeutic intervention.
Face masks have become a critically important public health intervention after the COVID-19 pandemic. Multiple types of masks ranging from full face filtering to cloth masks have been developed and commercialized to facilitate protection against respiratory pathogens. Most of these systems are made with opaque fabrics and may prevent individuals from expressing emotions or for those who are deaf and hard of hearing, communicating. To date, few transparent face masks which also confer respiratory pathogen protection have been developed. This study will test the feasability and acceptability of two new masks, the SEEUS-95 mask and CrystalGuard mask which are both transparent versions of N-95 filtering face masks.
The purpose of this research study is to collect cells and liquid from the air passages of healthy adults, both smokers and non-smokers. These samples will be used for test-tube studies to explore mechanisms of diseases of the respiratory tract, and to compare the samples between people who smoke cigarettes and people who don't. Obtaining these samples requires an invasive procedure called "bronchoscopy".
- Estimate the incidence rate of hMPV infection detected by RT-PCR from frozen nasal wash aspirates in children at high risk for severe LRI disease (hospitalized at \<2 years of age).
The purpose of this observational trial is to advance digital health monitoring through the analysis of Photoplethysmography (PPG) waveforms collected via RE.DOCTOR Vitals software. The study aims to collect a diverse and extensive dataset of PPG waveforms, alongside traditional physiological measurements, for the purpose of enhancing existing algorithms and machine learning models used in health monitoring. The primary focus is on improving the accuracy and reliability of algorithms in interpreting PPG data to derive meaningful insights into physiological parameters. The main questions it aims to answer are: * How can extensive datasets of PPG waveforms be utilized to enhance existing algorithms and machine learning models? * How do correlations between PPG waveforms and key physiological parameters (such as glucose levels, blood pressure, heart rate, respiration rate) contribute to refining algorithms for more accurate and reliable health predictions? Participants will be asked to: * Continuously monitor their health using smartphone applications. * Allow the collection of PPG waveforms in diverse settings. * Engage in tasks related to monitor health parameters using medically approved devices
The goal of this randomized controlled trial is to evaluate the impacts of an attachment-based intervention (Attachment Biobehavioral Catch-Up (ABC) and Home Book-of-the-Week (HBOW) program on emerging health outcomes (i.e., common childhood illnesses, body mass index, and sleep) in low-income Latino children (N=260; 9 months at enrollment). It is hypothesized that children randomized to ABC will have better health outcomes in comparison to the HBOW control group.
This observational clinical trial is designed to confirm whether RESP™ Biosensor could be deployed to support clinical decision making in challenging pediatric cases, minimize clinician-to-clinician variability in lung sound interpretation, obviate the need to disrupt change of shift or chart rounds with physicians, and create a durable archive of the patient's lung sounds for longitudinal comparison within or across hospitalizations.
This goal of this study is to assess the suitability of the HealthBeacon Injection Care Management System (ICMS) as a Remote Therapeutic Monitoring (RTM) device for patients on injectable medications in the home-setting, for the management of respiratory disorders. The HealthBeacon ICMS is composed of the Smart Sharps Bin, Companion App and Care Team support. The Smart Sharps Bin a digitally connected sharps container and is pre-programmed with a patient's injection schedule. It creates a time-stamped record of each used injection deposited into it to calculate a patients' adherence to treatment. Following disposal, the next date of injection and rotating injection site is updated without requiring any extra work on behalf of the patient. The system also proactively supports enhanced compliance through a series of smart dose reminders and intervention calls, to help patients stay on track. Clinical teams can then review patient adherence data remotely via an online platform. The main aims of this study include the following: * To demonstrate the suitability of the HealthBeacon ICMS as an RTM device for respiratory patients through successful billing and reimbursement for physicians * To provide data to support the reimbursement of the HealthBeacon ICMS by Private Payors in the future Participants prescribed injectable medication for the treatment of a diagnosed respiratory condition will be enrolled by the Principal Investigator (PI) and referred to HealthBeacon. Participants will then be provided with access to the HealthBeacon ICMS to remotely track and support their adherence to treatment in the home-setting. Participants will use the system for 6 months and their adherence data during this time will be collected, which the PI and clinical team involved will be able to remotely access and review. At various stages of the study, the applicable RTM codes will be billed for, for each participant. These stages include when providing each participant with access to the HealthBeacon system, including the Smart Sharps Bin, when providing each participant with education on how to use the device, and when the clinical team monitors each individual patients' adherence data collected by the HealthBeacon system on a monthly basis.
