Active clinical trials for "Asthma"

Peak inspiratory flow (PIF) may be due to respiratory muscle strength, especially in those with severe airflow obstruction. PIF appears to be lower in children and adolescents with asthma than in non-asthmatics and correlates positively with age, height, weight, and respiratory muscle strength. Although physical activity and fitness are also believed to be important in lung health, the relationship between lung function and physical fitness is unclear. It measures dynamic lung volumes, s-index and PIF and provides information on dynamic lung function in children and adolescents. In this study, the dynamic components of the lung will be compared between asthmatic and healthy children, and the relationship between respiratory parameters and physical assessment, such as physical fitness, activity and functional capacity, will be investigated in children with asthma.

To study the expression level of biomarkers such as GITRL in peripheral blood of children with asthma and analyze their correlation with the severity of asthma. To study the predictive value of biomarkers level for the occurrence and development of asthma. And to provide supplementary detection means and predictive indicators for the diagnosis of asthma and the severity of asthma.

Pregnancy may impact treatment adherence in women with asthma. This is a major risk factor for asthma exacerbation, which may have an important impact for both women and the babies. This study aims to evaluate the impact of a targeted patient education action tailored for pregnant women with asthma.

Childhood asthma is the most common chronic respiratory disease in childhood. The essence of asthma is chronic airway inflammation and airway hyperresponsiveness.The physiological characteristics of children and adults are very different, and the compensatory ability is very strong. There are often no obvious symptoms at the early stage of attack, or only intermittent or persistent cough of different degrees, without typical chest tightness and asthma.However, at this time, certain physiological indicators such as blood oxygen, heart rate, respiratory rate may have been significantly abnormal.If the disease continues to deteriorate and progresses to decompensation, it can quickly move from an asymptomatic state to a failure stage.Therefore, dynamic and accurate acquisition of real-time vital signs and assessment is of great significance for early warning and improvement of prognosis of asthma attacks in children.Intelligent wearable devices can be used to acquire real-time physiological index data of users, such as heart rate, blood oxygen, exercise and sleep dynamic data.An in-depth analysis of long-term and multi-scene dynamic data before and after asthma attacks can establish an early warning model for children with acute asthma attacks by wearable wrist smart devices, which may provide important help for severity assessment, follow-up tracking and out-of-hospital prevention and control of the disease.

The purpose of this study is to learn more about how asthma develops in early childhood. This will help doctors understand how to prevent and treat asthma better.

Deep Phenotyping of adult asthma patients: severity from mild to severe both atopic and non-atopic both childhood and adult onset both smokers and non-smokers corresponding pediatric cohort (Pediatric Arm of DZL All Age Asthma Cohort) with equivalent SOPs regarding collection of biomaterial and clinical data incl. lung function, further processing of biomaterial and further analyses

This research study is being done to learn more about severe asthma by comparing people with severe asthma to those with milder forms of asthma and people without asthma, at baseline and over time. Individuals are being asked to join a research study to help understand the differences in the lungs and blood of participants with severe asthma compared to those with milder asthma and healthy individuals, as well as differences in overall health. Investigators also want to determine whether these differences predict asthma-related and biologic outcomes over 1 year of follow up.

This will be a single site, mechanistic study of asthmatic subjects and healthy, non-asthmatic controls involving a baseline characterization visit and a research bronchoscopy visit. We will identify differences in airway epithelial epigenetic enhancer signatures in asthma, by analyzing freshly isolated airway epithelial cells from healthy controls and from well-characterized subjects with asthma.

Asthma is a chronic inflammatory airway disease that leads to episodic symptom exacerbations, which exerts a substantial burden on quality of life and can influence other health domains if not adequately controlled. Asthma prevalence rates have increased in the past decade, affecting 8.4% (25.7 million people) of the United States population. The economic costs of asthma have been estimated annually with $56 billion in the US alone. Despite progress in pharmacological treatment, overall asthma control remains unsatisfactory and treatment non-adherence is extremely high. Asthma is particularly under diagnosed and understudied in aging adults. This problem will increase in coming decades given demographic trends and will disproportionally contribute to the societal and personal economic costs associated with asthma treatment and management. In the proposed 4-year project we will evaluate, in a two-session assessment recruiting a total of 126 asthma patients and 66 healthy controls aged 40-69 years, the extent to which asthma and aging are associated with changes in cognition and brain chemistry, structure, and function.

Asthma affects 1 in every 12 persons in the U.S., resulting in 1.9 million ED visits annually; however, the impact of ED care on patient-reported outcomes after acute exacerbations is unknown. The proposed research will train a physician-scientist to develop a novel instrument to assess patient-reported outcomes after adult ED asthma visits, evaluate the association between ED clinical processes and patient-reported outcomes, and test the association between patient-reported outcomes and subsequent acute care utilization. The candidate will acquire skills in patient-centered research, instrument development and validation, and risk adjusted outcome measurement that will enable her transition to independence.
