The clinical trial is designed to evaluate the non-inferiority of CHF1535 100/6 µg NEXThaler versus CHF1535 100/6 µg pMDI on the onset of relief from methacholine-induced bronchospasm, in terms of pulmonary function (i.e. change in Forced Expiratory Volume in the 1st second, FEV1, from baseline to 5 min after study drug intake) in asthmatic patients.
This was a randomized, placebo-controlled, double-blind, six-sequence, three-period cross-over study in asthma patients. The study consisted of a 14-day screening period, followed by a 14-day run-in period, and a treatment epoch which consists of three treatment periods, with a minimum duration of 14 days each followed (for the 2 first treatment periods) by a wash-out period. The duration of each treatment period may be extended up to a duration of 18 days if needed for operational reasons. The third treatment period was followed by a Study Completion evaluation at 1-7 days following the last dose. The treatment periods were separated by wash-out periods of 14 to 21 days duration.
This protocol concerns the implementation and evaluation of an intervention designed to realign the existing cadre of Community Health Workers (CHW) in Neno District, Malawi to better support the care needs of the clients they serve. The proposed intervention is a 'Household Model' where CHWs will be assigned to households, rather than HIV or TB specific patients, and will be trained to provide support for a wider range of conditions including HIV, hypertension, diabetes, and pediatric malnutrition. The new model is designed to improve retention in care for clients with chronic, non-communicable diseases, along with increased uptake of women's health services and treatment for pediatric malnutrition, while sustaining the high retention rates for clients in the HIV program. Eleven sites (health centres and hospitals) were arranged into six clusters by estimated size of the catchment area populations, with a population range of 11,680 to 26,260 and an average population of 20,400. The order in which the intervention will be rolled out across the sites will be randomized so that the intervention can be evaluated in a stepped-wedge cluster randomized controlled trial. These clusters were grouped based mostly on geographic location but also on catchment area sizes, in order to maximize feasibility of training for the CHW team and not overload CHW training sessions with too many trainees.
The goal of the Upstate KIDS Study is to track the growth, development and long-term health of children given the increasing use of infertility treatment, occurrence of maternal obesity and pregnancy complications, and rising maternal age at birth.
The objectives of this study are to determine the sensory-mechanical responses to Eucapneic Voluntary Hyperventilation (EVH) and Mannitol in individuals with cough variant asthma (CVA) and methacholine-induced cough with normal airway sensitivity (COUGH) and compare these responses to a control group of healthy individuals without asthma or chronic cough. We hypothesize: 1. EVH and Mannitol cause dyspnea, cough, small airway obstruction with resultant dynamic hyperinflation, gas trapping and autoPEEP in individuals with CVA and COUGH, but not healthy controls. 2. The sensory-mechanical responses to both hyperosmolar challenges (EVH and Mannitol) are comparable within groups (CVA, COUGH and healthy controls).
This is a prospective, remote observational study of adults with persistent asthma who are managed on inhaled corticosteroids.
New insights of small airway contribution to asthma have been gained. Poor levels of control and recurrent exacerbations were shown to have the phenotypic counterpart of asthma with predominant small airway involvement. Very few pathological specificities were identified at this site: mast cells infiltration was suggested as the specific inflammatory change when compared to the proximal airways.Biomarkers in asthma are still complex to validate, especially in the blood, since compartmentalisation is intense in the lung and the airways, a property attributed to the filtering role of the lung to maintain homeostasis. Over the last few years, Fraction exhaled Nitric Oxide (FENO) was developed as a non-invasive and indirect reflection of airway eosinophilic inflammation]. In the blood, peripheral eosinophil counts were shown as a correct T helper 2 (TH2)-phenotype identifier but not perfectly related to airway eosinophilic infiltration. Club cell secretory protein (SCGB1A1) levels have been shown to have some relevance in asthma, chronic obstructive pulmonary disease (COPD), BOS, sarcoidosis, and lung cancer.A biomarker for small airway disease in asthma may improve the management of the disease, identify areas of therapeutic resistance and constitute a therapeutic guidance tool. In this study, investigators aimed to assess small airway involvement in asthmatic women as far as they could. For this purpose, investigators analysed trends in air trapping by acquiring expiratory CT slices at each dose during a bronchoprovocation test with metacholine. Biomarkers were subsequently tested and confronted to clinical and demographical characteristics in their ability to predict the small airway involvement index obtained at CT.
The investigators surveyed the prevalence of animal allergy and sensitization to animal allergen among participants in international symposium of Korean association for laboratory science (laboratory animal researchers) and companion animal exhibition (pet owner and pet-related industry workers).
The purpose of this study is to provide long term safety data of QVM149 in Japanese patients with asthma for the registration of QVM149 in Japan.
