Pneumonia is a major infectious cause of death worldwide and imposes a considerable burden on healthcare resources. Obstructive lung diseases (COPD and Asthma) are increasingly important causes of morbidity and mortality worldwide. The patients with community-acquired pneumonia (CAP), and acute exacerbations of obstructive lung diseases commonly present with similar signs and symptoms. For antibiotic use, the rapid and accurate differentiation of clinically relevant of bacterial lower respiratory tract infections from other mimics is essential. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid has both extracellular and intracellular effects in mammalian cells. S1P is involved in many physiological processes including immune responses and endothelial barrier integrity. In term of endothelial barrier integrity, S1P plays a crucial role in protecting lungs from the pulmonary leak and lung injury. Because of the involvement in lung injury, S1P would be the potential biomarker of pneumonia. Based on the above evidence, S1P plays an essential role in the pathobiology of pneumonia was hypothesized.
The purpose of this study is to establish the reference values of impulse oscillometry (IOS) in healthy Chinese, and compare the indices of IOS in patients with lung disease, such as chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease (ILD), and upper airway Obstruction (UAO).
assess the efficacy and safety of Salmeterol Xinafoate and Fluticasone Propinate Powder for inhalation (50ug/250ug) in combination with seretide to patients with Asthma. a randomized, double-blind, double-dummy, positive-controlled, parallel-group trail.
Phase I: To develop and validate laboratory urine and blood test for the detection of medications commonly used in the treatment of asthma Phase II: to test the developed assay in the clinic, to determine its practicality to conduct, and its clinical utility in adherence assessment.
Determining how memory T helper type 2 (Th2) initiate recall responses to aeroallergens has the potential to change the therapeutic approach to allergic asthma, the most common asthma subtype. ~5-10% of effector Th2 cells recruited into the lung give rise to long-lived tissue resident memory cells that are poised to respond upon allergen re-exposure.Consequently, targeting memory Th2 cell activation is an attractive therapeutic strategy. However, it is not well understood how allergen inhalation initiates a memory Th2 cell response in the lung. The focus of this new study on the role of lung-resident memory Th2 cells in orchestrating the recall response to allergen in the lung, including the recruitment and activation of circulating Th2 cells, is a natural, timely and exciting extension of the investigators' ongoing Allergen Challenge Protocol.
This is a single centre exploratory study that aims to apply hyperpolarized xenon-129 (129Xe) magnetic resonance imaging (MRI) methods and measurements in individual patients with and without lung disease to better understand lung structure and function and evaluate response to therapy delivered as a part of clinical care.
Health disparities in pediatric asthma persist, with Latino children demonstrating increased asthma morbidity. Middle school children with asthma have greater morbidity than children from any other age group and spend a majority of their day in school, where they must manage any asthma. The investigators developed and piloted a novel group-based intervention - ASMAS (Asthma Self-MAnagement in Schools) in two geographic areas with a high prevalence of urban and Latino children with asthma: Providence, Rhode Island, and San Juan, Puerto Rico. ASMAS is a 4-session, peer-facilitated asthma self-management intervention specific to the school setting for Latino middle school (6th-8th graders) children. It is delivered by trained High School Juniors and Seniors of Latino descent with asthma. The preliminary effects of ASMAS for improving asthma outcomes and self-management relative to controls were demonstrated in a previous intervention development study. This study will evaluate ASMAS through a large-scaled Randomized Control Trial with urban middle school students who have persistent asthma in Providence, Rhode Island and San Juan, Puerto Rico and will identify barriers and facilitators to the implementation of ASMAS. These results will inform future, large-scale dissemination in other urban school settings.
This study will evaluate a new imaging technology, called optical coherence tomography (OCT) to examine the asthmatic airways before and after bronchial thermoplasty, which is a new treatment option for severe asthmatic patients. The aim of this study is to learn more about how airways respond to this new treatment. In the future the investigators hope OCT will aid clinicians in the initial assessment, management and long-term follow up of patients receiving bronchial thermoplasty.
This study has the aim to assess the effectiveness of the Ai Chi method as an adjunct therapy in the treatment of children with asthma.
