Filter by:The goal of this pilot study is to implement directly observed therapy with preventive asthma medications through a partnership with the school nurse (with input and direction from the primary care provider) to assure that the teen receives guideline based preventive medications, and provide a motivational interviewing intervention to help the teen transition to independence with their medical treatment plan. We hypothesize that this community-based pilot intervention will; 1) be feasible and acceptable among this population and among school personnel, and 2) yield reduced asthma morbidity (symptom-free days, absenteeism, and emergency room / urgent care use for asthma care). We anticipate that enhancing preventive healthcare for urban teens with asthma through partnerships with schools will yield improved health, prevention of suffering, decreased absenteeism from school, and reduced healthcare costs. This new method of preventive care delivery could be sustained within the school nursing system, and could be implemented in schools nationwide. Further, it could be applied to other chronic illnesses affecting disadvantaged populations.
The overall goal of this project is to evaluate whether a multifaceted prompting intervention, administered in the urban primary care office setting, reduces morbidity among urban children with asthma. This study builds on our experience with a pilot study in two urban continuity clinics, in which we found that prompting clinicians about asthma severity and care guidelines at the time of an office visit resulted in improved preventive care delivery to inner-city children. This type of prompting program has the potential to substantially improve care for impoverished children with asthma, and we propose to establish: 1) whether these findings can be replicated in a similar study including a larger sample of urban children from different types of practices, and 2) whether the positive effects can be enhanced by more specific prompting directed towards both the provider and the caregiver and by providing practice-level supports and feedback. We hypothesize that children receiving a multifaceted prompting intervention (MPI) will experience less asthma-related morbidity (defined by symptom-free days at the 2-month follow-up) compared to children receiving usual care. Our secondary hypothesis is that children receiving the MPI will receive improved preventive asthma care (defined by guideline-based corrective actions taken at the index visit) compared to children receiving usual care.
The purpose of this study is to verify and validate the intrinsic diagnostic value in terms of sensitivity and specificity of proteomic profiles determined during a pre-study for discriminating between allergy related asthma and allergy related rhinitis.
This is a 6 week study to assess the effect of BI 671800 in patients with asthma. It is a double blind, parallel arm trial testing the safety and efficacy of BI 671800. The main objective is to assess the effect on lung function. The study will also provide data on the pharmacokinetics of BI 671800.
This interdisciplinary multi-level study moves the research in asthma health disparities from descriptive studies of individual constructs and contexts to testing an integrated, multi-factorial model among Latino families and children with asthma. The investigators seek to gain a more thorough understanding of the interaction of individual characteristics, cultural and experiential factors, social-environmental context, and healthcare system factors on parents' illness representations, use of CAM and controller medications, and children's asthma health outcomes. This will be a one-year longitudinal, multi-site (Phoenix, AZ and Bronx, NY) study among samples of Mexican (N=300) and Puerto Rican (N=300) parents and children aged 5-12 who have asthma. Aim #1: Are there differences in illness representations between Mexican and Puerto Rican parents due to social and contextual factors (i.e., acculturation, education, parental age, poverty, child's illness duration, household members with asthma, and parent-healthcare provider relationship)? Aim #2: Are disparities in asthma control between Mexican and Puerto Rican children due to differences in parents' treatment decisions (CAM and controller medication use) and changes in illness representations over a one year period after controlling for the effects of acculturation, social and contextual factors, environmental triggers, and advice received from others?
A comparator study to assess safety and efficacy of Flutiform® compared with symbicort turbohaler in asthma patients with moderate to severe persistent, reversible asthma.
Exercise induced bronchospasm (EIB), also known as exercise induced asthma (EIA) is a transient obstruction to airflow triggered by exertion. It is now a well known identity, center of discussion in recent years, particularly in the athletes' world. It is more common in asthmatic individuals (regardless of severity of disease), but it is also seen in otherwise healthy subjects, leading to the general consensus that the pathophysiology is different than asthma. The concentration of exhaled nitric oxide (FeNO) in various airway & respiratory disorders, particularly asthma, has been deeply studied. Its use for noninvasive monitoring of asthma control (reflecting airway eosinophilic inflammation) is being closely examined and put into clinical practice. FeNO is significantly elevated in asthma. Elevated FeNO levels have also been noted in patients hospitalized with a COPD exacerbation, acidosis, rhinitis, bronchiectasis, active pulmonary sarcoidosis, active fibrosing alveolitis, and acute lung allograft rejection. Decreased FeNO levels have been seen in patients with primary ciliary dyskinesia, cystic fibrosis, PiZZ phenotype-related alpha-1 antitrypsin deficiency, and pulmonary hypertension Two studies have addressed the variations on FeNO after EIB and they had contradictory results. Scollo et al. found no change in FeNO in either healthy or asthmatic children after a 6-min of vigorous exertion in an exercise laboratory when they studied 24 asthmatic and 18 control children. Terada et al. reported, for 39 subjects, a decrease in FeNO in subjects with EIB and an increase in healthy controls. It is well accepted that the pathophysiology of exercise induced bronchospasm it is not similar to that of asthma. Certainly the inflammation in the airway does not appear to be eosinophilic. Understanding the disease mechanism is a key factor to adequately manage it. This will be a prospective study measuring online exhaled nitric oxide involving children 8 to 21 years old. The study group will include any children coming for a pulmonary exercise test in the exercise laboratory located in the Pediatric Pulmonary Division office. The study will be conducted from the fall of 2009 until the spring of 2011. The change in the FeNO measurement will be correlated with the change in % predicted FEV1. We will consider significant a decrease in FEV1 post exercise of 15% and/or decrease on FEF25-75 of 20% that will persist until 15 minutes after completing exercise. We will also record any symptoms reported by the subject during or after the test. An exercise test is a standard of care when suspecting exercise-induced asthma. The subjects and their parents coming for exercise test will be offered the opportunity to participate in the study. The subject will come for the exercise test and will perform spirometry and FeNO measurement prior to start the test. According to our exercise laboratory protocol 1 minute of warm up at a low speed, followed by 6 minutes of high speed (enough to increase heart rate to 90% predicted or more) and 3 minutes of cool down at a low speed will be performed. Then spirometry will be repeated at 3, 5, 10 and 15 minutes and FeNO measurement will be taken at 5, 10 and 15 minutes. We will analyze the data to find if there is any significant change in FeNO measurements after exercise.
The purpose of this study is to see whether a new investigational drug (Imatinib) may help improve asthma in people whose symptoms are not well controlled with high dose inhaled corticosteroid treatment.
This controlled study is undertaken to investigate the effects of a long term outpatient training program on physical fitness and quality of life in elderly asthmatics.
Background: Occupational exposures are thought to be responsible for 10-15% of new-onset asthma cases in adults, with disparities across sectors. Because most of the data are derived from registries and cross-sectional studies, little is known about incidence of occupational asthma (OA) during the first years after inception of exposure. This study focuses on this early asthma onset period among young workers in the bakery, pastry making and hairdressing sectors in order to assess early incidence of OA in these "at risk" occupations according to exposure duration, and to identify risk factors of OA. Methods: This study is a longitudinal retrospective study with a nested case-control to identify risk factors of OA. The assessment of incidence evolution is made by exploring a series of promotions (or retrospective cohorts) with increasing duration since at work. The study population is composed of subjects who graduated between 2001 and 2006 in sectors where they experience exposure to organic or inorganic allergenic or irritant compounds (with an objective of 150 subjects by year) and 250 young workers with no specific occupational exposure. This study is a descriptive, monocentric, longitudinal and retrospective study with cross-sectional measurements.
