15 Clinical Trials for Various Conditions
A phase I clinical research study aimed at determining mechanisms that regulate airway mucosal inflammation in asthma endotypes using intranasal administration of endotoxin (lipopolysaccharide from E. coli) in healthy controls and subjects diagnosed with asthma.
This study is focused on the pathophysiology underlying the association between exposure to particulate pollutants and risk for/response to viral infection. The investigators hypothesize that exposure to wood smoke particles (WSP) enhances influenza virus-induced granulocyte and NK cell activation, via hyaluronic acid-mediated effects on IFNg production. Oxidant stress and viral replication may also be affected. As an NIH funded ViCTER project, the purpose of the study is also to test novel assays of granulocyte activation (Doershuk lab) and lipid mediator activation (Albritton lab) which have not previously been used in this type of research. Healthy, nonsmoking adults age 18-40 years will be recruited. This is a randomized, placebo controlled study comparing NLF granulocyte responses to LAIV administered after either WSP or clean air, in normal healthy volunteers. Subjects receive either WSP or placebo (clean air), followed by a standardized dose of LAIV and serial post-infection sampling of nasal lavage fluids, nasal biopsy and blood
To investigate if low level ozone exposure will cause measurable inflammation in nasal cells.
The goal of the study is to examine the possible underlying causes of sleep apnea (a disorder in which there are problems with breathing during sleep) in World Trade Center Responders. The study will look at the relationship between sleep apnea and various nose and throat conditions. Specifically, the study will look at upper airway disease (problems with the nose and throat), nasal inflammation, and nasal resistance (the amount of airflow through the nose). Subjects will have a physical exam and answer questions about nasal symptoms and sleeping problems. Nasal lavage (washing the inner nasal passages) will be performed on the subjects and markers of inflammation will be measured in the lavage fluid. Rhinomanometry (measuring the airflow through the nose) will also be performed to measure the degree of airflow obstruction. All subjects will be asked to perform in-home sleep apnea monitoring. Those subjects who are diagnosed with sleep apnea will test two treatment methods. Sleep apnea is treated by using a CPAP (continuous positive airway pressure) device. This device blows air into a mask worn by the patient during sleep. The two treatment methods that will be tested are the fixed pressure CPAP (pressure is constant during use) and CPAP-flex (pressure decreases when the subject exhales). Patients will be randomly assigned to one treatment method for one month then crossed to the other treatment method for the next month. The investigators will determine if patients with certain nasal conditions (high nasal resistance) are more likely to use CPAP-flex rather than CPAP.
The purpose of this pilot study is to evaluate allergen-induced nasal airway inflammation following nasal application of felis domesticus, or cat, extract in e-cigarette users, cigarette smokers, and non-smokers.
The purpose of this pilot study is to evaluate allergen-induced nasal airway inflammation following nasal application of Dermatophagoides farinae (Der f), or house dust mite, extract in e-cigarette users, cigarette smokers, and non-smokers.
This Study evaluates the effect of adding Non-steroidal anti-inflammatories (NSAIDs) to the post-operative pain management of sinus surgery patients and wether or not this addition reduces or eliminates the need for narcotic pain medications. Patients will be instructed to take an NSAID regimen after surgery and will be instructed to take narcotics only for breakthrough pain.
To demonstrate the safety and effectiveness of Sonu for the treatment of pediatric patients with moderate to severe nasal congestion.
The goal of this clinical trial is to evaluate the effects of using the SinuSonic on psychological and physical well-being in adults who have nasal/sinus congestion. The study aims are: * Aim #1: to evaluate the effect of the SinuSonic on physical and psychological well-being in individuals with chronic nasal congestion; * Aim #2: to evaluate the relationship between autonomic reactivity and psychological well-being (i.e., anxiety and depression) in individuals with chronic nasal congestion; * Exploratory Aim: to evaluate the impact of adverse experiences on physical and psychological well-being in individuals who experience chronic nasal congestion. Participants will be asked to complete self-report measures of physical health, mental health and autonomic regulation before using SinuSonic (i.e., baseline research session) and after 5 weeks of directed use (post-intervention). Demographic information and adverse experiences will be documented during the baseline research session. Participants will be asked to document (weekly) current nasal symptoms and SinuSonic usage.
To demonstrate the safety and effectiveness of Sonu for the treatment of patients suffering from moderate to severe nasal congestion.
Kennedy et al, in a study of pediatric Emergency Department (ED) use by newborns less than 14 days of age, revealed that half of all visits in this population were non-acute problems. Other pediatric ED utilization studies have shown similar findings in that 32% to 72% of all visits were for non-urgent problems. Many studies have found that primiparity and young maternal age are associated with non-acute ED presentations. A recent factor that has been investigated is the effect of early neonatal discharge. Some other factors are nonwhite mothers and mothers on Medicaid. Zandieh et al, found additional predisposing determinants for non-urgent ED visits, such as single parenthood, Hispanic ethnicity, and having perceptions that their child's overall physical health was poor. Paradis et al found that parents receiving a video intervention rated higher confidence with specific infant care skills and reported feeling better prepared to care for their baby, compared to parents receiving only handouts. However, there isn't any reported study that evaluates the benefits of receiving both, a video intervention along with handouts. Aim: to demonstrate whether conducting anticipatory guidance related to non-urgent problems will reduce non-urgent ED visits, compared to care as usual (CAU) anticipatory guidance (Sudden Infant Death Syndrome and Shaken Baby Syndrome videos; and unstructured talk about jaundice, vaccinations, appointments, care of umbilical stump, normal urination and bowel movement, fever).
The primary goal of this post-marketing surveillance study is to assess whether surgical turbinate reduction performed using a Coblation® device is associated with reduced nasal obstruction symptoms.
Allergic airway disease is a term used to describe conditions such as allergic rhinitis and asthma. Among other causative agents, air pollutants and diesel exhaust in particular, have been shown to create and also worsen existing allergic airway disease. These inhaled pollution particles have oxidative properties that drive inflammation-related effects through specific metabolic-associated processes. These processes are not adequately suppressed by current therapeutics. The purpose of this study is to explore the effects of broccoli sprout extract on the inflammatory process in the nose caused by diesel exhaust particles, which are important elements in air pollution. Broccoli sprout extract is a very potent inducer of Phase II enzymes (natural antioxidants).
Upper respiratory infections (URIs) have long posed a significant burden to the US healthcare system. Well before the coronavirus disease of 2019 (COVID-19) pandemic they have been among the most common acute outpatient illnesses, causing 75-100 million physician visits each year on average, and costing the health care system billions of dollars annually. This double-blind randomized placebo-controlled study tested the efficacy of two anti-inflammatory throat sprays against placebo and against a throat spray taken in conjunction with 325mg of aspirin, a well-known systemically administered cyclooxygenase (COX) inhibitor. Participants having common cold symptoms lasting less than two days were enrolled and given treatment to administer at home. Various common cold symptoms were assessed and measured via clinically validated self-assessment scales. Participants were screened for influenza and COVID-19 before enrollment and were excluded if found positive.
This aim will examine the acute and subacute exposures to electronic cigarette (EC) vapor generated from e-liquids without nicotine (NFEC) on life-time non smokers subjects by measuring changes in nasal ion transport and TGF-β levels. Nasal ion transport will be assessed by nasal potential difference (NPD). Tumor growth factor (TGF)-β levels (mRNA and protein by ELISA) will be assessed on nasal cells and lavages.
