Filter by:Asthma is the most common chronic disease of childhood and is responsible for large portion of pediatric admissions to Canadian hospitals. There is evidence that clinical pathways allow for optimal delivery of care and may result in decreased length of stay, leading to important economic benefits. Weaning of asthma medications prescribed for asthma exacerbation is not standardized in the current model of care. Currently, weaning is performed by ward physicians; in a teaching hospital, this most often done by residents staff. Differences in practice between different physicians, delays in patient assessment and adjustment of doctor's orders, likely prolong the hospital stay for children admitted with asthma. This study's main objective is to determine the effect of a nursing-driven clinical pathway on children's length of stay when admitted to hospital with a diagnosis of acute asthma exacerbation. The pathway will allow nurses to wean a specific type of medication(β2-agonist), as compared to the current standard of care, which dictates that a physician writes an order to wean the medication. Number of administered β2-agonist treatments will be compared between both groups, as well as asthma-related health care utilization within two weeks of hospital discharge. Nursing, physician, and patients' satisfaction with the pathway will be evaluated, and a cost minimization analysis will be performed. This study has the potential to improve resource use efficiency, increase patient safety by avoiding administration of unnecessary medications, and ameliorate quality of care by standardizing the care of children admitted to the hospital with a diagnosis of acute asthma exacerbation. The results of the study will be disseminated across the Canadian Health Care System with the goal of improving outcomes of children admitted to hospitals with acute asthma exacerbations.
This is a Phase 3, randomized, placebo-controlled, double-blind,double-dummy, parallel-group, 12-week study in male and female patients, 12 years of age and older, with persistent asthma.
Introduction: Recently it has involved the role of TLR (toll-like receptors) in the pathogenesis of asthma. TLRs are a family of proteins responsible for the recognition of Pathogen-Associated Molecular Patters (PAMPs). The possible role that TLRs play in IgE-dependent asthma (not eosinophilic) and its recognition as a new endotype asthma, could open new therapeutic expectations. Objective: To analyze the expression of TLR 2 and 4 in monocytes/ macrophages and neutrophils in peripheral blood and induced sputum from asthmatic patients
In a society where exercise is prescribed by physicians to increase physical condition, improve dietary habits and reduce cardiovascular risk, the impact of exercise, acute or chronic, and diet in inflammation and immunity is unknown. Specific populations can have different responses towards acute and chronic exercise. Moreover specific conditions, like the type of meal ingested, can interfere with these responses. The true effect of pre-competitive meal exercise in the immunity and inflammatory response is unknown. Acute physical inactivity periods, commonly happens during daily life, related to work or acute illness. New evidence points out that it induces immediate metabolic and endocrinological changes, these can might also be associated with changes in immune response. Aims of this project are: 1. to assess the effect of the precompetitive meal on the inflammatory, neuro-immune and metabolic response to exercise; 2. to assess the effects of sedentary behaviour on inflammatory, neuro-immune and metabolic response; 3. to assess differences in changes between healthy, asthmatic and obese subjects
Patients with persistent asthma have different inflammatory phenotypes. The electronic nose is a new technology capable of distinguishing volatile organic compound breath-prints in exhaled breath among different pulmonary diseases. Question of the study. Is the electronic nose breath-print analysis able to discriminate among different inflammatory asthma phenotypes?
Macrolides are potent inhibitors of cytochrome P450 isoenzyme 3A4（CYP3A4）and thus interfere with the pharmacokinetics of many other drugs that are metabolised by this enzyme like theophylline.The aim of this study is to determine whether azithromycin can effect theophylline metabolism in patients.
This is a single centre, randomized, double-blind, placebo-controlled, single ascending dose study, in which the safety and pharmacokinetics of laninamivir octanoate administered by inhalation via the TwinCaps® DPI will be assessed in adults with mild or moderate chronic asthma.
The aim of the prospective cohort study is to: (1) document the magnitude of response to oral corticosteroids administered to children presenting to the emergency department with moderate or severe asthma and (2) quantify clinically available potential determinants of the response to corticosteroids, such as age, gender, triggers of the index exacerbation, environmental tobacco smoke (ETS), gene polymorphisms, and their interactions.
The purpose of this study is to assess the effects of regular exercise on physical fitness, asthma control, and quality of life among adult asthmatics.
We hypothesized that the ability of the Lung Flute to enhance mucus clearance from the lower airways could be used to improve asthma control, if the device is used on a chronic basis. The primary end point of the study is the comparison of Asthma Control Test (ACT) - a validated questionnaire for asthma control and exhaled NO before, during and after using the lung flute. Several secondary end points were assessed for efficacy and safety, including health status, spirometric lung function, "stepping down" controller therapy and daily albuterol use.
