Active clinical trials for "Lung Diseases"

The use of saturometry at home is more and more widespread in patients suffering from interstitial pulmonary diseases (IPD), the patients seeing it as reassurance and a concrete way to follow the evolution of their disease. However, there are no studies evaluating the real clinical benefit of taking saturation at home in this population. In addition, clinical experience seems rather to demonstrate an increase in the anxiety level and the number of clinically unnecessary consultations related to the use of this measure. The secondary objectives are to determine the impact of this measurement on: (1) the health care use (telephone calls, medical consultations and hospitalizations), (2) dyspnea score, (3) the anxiety and depression score (HADS score) and (4) the physical activity level. The exploratory objectives will be to determine if the measurement of saturation at home makes it possible to (1) predict the occurrence of acute exacerbations of fibrosis, (2) effectively predict the decline in respiratory function tests and (3) 1-year mortality. The investigator will also assess whether this measure makes it possible to screen patients with oxygen therapy needs at home. The investigator hypothesize that measuring oxygen saturation at home will lead to a significant deterioration in quality of life, an increase in the use of health care, a significant increase in the rate of anxiety and depression, dyspnea and a decrease in the physical activity level.

Sufficient muscle strength helps to get out of a chair and can prevent falls. Up to 30% of older adults experience age-related loss of muscle strength, which can lead to frailty and health instability. Exercise helps to build muscle, maintain bone density and prevent chronic disease, especially during the aging process. In older adults at risk of mobility impairment, exercise greatly reduced incidence and effects did not vary by frailty status. However, more than 75% of Canadian adults ≥18 years of age are not meeting physical activity guidelines. In addition, it is known that malnutrition, including low protein intake, may lead to poor physical function. While there are services to support exercise and nutrition, barriers to implementing them persist. The COVID-19 pandemic has exacerbated the potential for physical inactivity, malnutrition, and loneliness among older adults, especially those with pre-existing health or mobility impairments. Now and in future, alternate ways to promote exercise and proper nutrition to the most vulnerable are needed. The investigators propose to adapt MoveStrong, an 8-week education program combining functional and balance training with strategies to increase protein intake. The program was co-developed with patient advocates, Osteoporosis Canada, the YMCA, Community Support Connections and others. MoveStrong will be delivered by telephone or web conference to older adults in their homes, using mailed program instructions, 1-on-1 training sessions through Physitrack®, as well as online nutrition seminars and support groups over Microsoft® Teams. The primary aim of this study is to assess feasibility as determined by recruitment (≥ 25 people in 3 months), retention (≥80%), adherence of (70%) and participant experience.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease that results in progressive airflow limitation and respiratory distress. Physiopathological features of COPD suggest that people who suffer from this disease have many risk factors for falls that have been identified in older individuals. Risk of falls is multi-factorial and impaired balance has been shown to contribute. The investigators aimed to demonstrate that, IMT performed during a PRP may improve Postural control in COPD patients.

The purpose of this study is to assess the effects of a complex telemedicine intervention as a part of an integrated care program for patients with chronic obstructive pulmonary disease (COPD) discharged from the hospital after disease exacerbation. Will be evaluated whether the intervention produces benefits in terms of mortality, reduction in hospital readmissions and health-related quality of life. In addition, the trial evaluates the economical and organizational impact of the new service and examines its acceptability by patients and health professionals.

The effectiveness of Bottle PEP in patients with Chronic Obstructive Pulmonary Disease

The purpose of the study is to assess the efficacy of high-frequency non-invasive ventilation on apnea duration, carbon dioxide clearance and oxygen delivery in healthy subjets and patients with lung disease.

This study will evaluate a complex intervention based on a patient management tool (PMT), combined with educational outreach to primary care doctors, nurses and other health workers, in the Brazilian city of Florianopolis. The intervention is aimed at improving the quality of respiratory care and respiratory health outcomes, and comorbid conditions, in adults with asthma and chronic obstructive pulmonary disease (COPD). The effectiveness of the intervention will be assessed by randomly allocating 48 primary care clinics to receive the intervention or not, and comparing patient and clinic level endpoints that reflect the health and quality of care provided over the following year. About 1250 patients known to have been diagnosed with asthma and 700 with COPD in participating clinics and will be included in the study. The primary endpoints for patients with asthma and COPD, respectively, will be composite scores indicating appropriate prescribing and diagnostic testing. The third primary endpoint, among all adult clinic users, will be rates of new diagnoses of asthma and COPD in each clinic. Secondary endpoints will include the individual components of the composite scores, health measures (hospital admissions and deaths), and indicators of appropriate management of comorbid conditions such as cardiovascular risk factors. Eligible patients will be identified and outcomes measured using electronic medical records.

Chronic Obstructive Pulmonary Disease (COPD) is the most common pulmonary disease, responsible for considerable morbidity and mortality and is the third leading cause of death worldwide. As well as its consequences in the lungs, COPD is well recognized to be associated with a range of important systemic consequences and co-morbidities. Interestingly, skeletal muscle dysfunction is noted in both early and advanced disease, suggesting its origins may not be wholly pulmonary. Treatment strategies targeting lung function are, unfortunately, of limited value. Given the burden of disease, it is becoming increasingly important that investigative and therapeutic work now focuses on other systemic characteristics and sequelae which define the disease phenotype. This is a randomized controlled trial of the effect of 14 days of voluntary reduced activity on muscle mass, muscle strength, body composition, and atrophy signalling in patients with COPD and age-matched controls. The primary hypothesis upon which this study is based is that a short reduction in ambulation will induce a transient reduction in quadriceps muscle mass, quadriceps strength and physical performance in patients with COPD compared to matched COPD patients whose mobility has not been restricted. The secondary hypothesis is that the magnitude of the above changes will be greater in physically inactive COPD patients compared to physically inactive age-matched controls. The overall aim of this research is to use an in vivo human model of 14 days of voluntary reduced physical activity to test the above hypotheses. If the model proves feasible, this will allow for earlier proof of concept studies of novel therapeutic agents.

Chronic obstructive pulmonary disease (COPD) is a condition defined as a disease state characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and is associated with an abnormal inflammatory response of lungs to noxious particles or gases, primarily caused by cigarette smoking. The accelerated decline in lung function is closely associated with an increased number of neutrophils in the sputum and hence with higher level of airway inflammation. It becomes clear that the inflammatory process potentiates as COPD progresses and exerts damage which is irreversible. Oxidative stress is inextricably linked to the inflammatory response. There is increasing evidence that an oxidant/antioxidant imbalance, in favor of oxidants, occurs in COPD. NAC has been reported to reduce the viscosity of sputum in both cystic fibrosis and COPD, facilitating the removal of pulmonary secretions. Moreover, by maintaining the airway clearance, it prevents bacterial stimulation of mucin production and hence mucus hypersecretion. The superiority of NAC over the other mucolytics may be in its anti-inflammatory and antioxidant properties and its mucolytic actions. The aim of this study is to evaluate the effects of treatment with NAC long on oxidative stress marker change and also explore the effect of NAC to airway inflammatory, lung function test and CAT scores. Selected oxidative stress marker was defined as 8 - isoprostane, protein carbonyl, DNA damage.

The short chain fatty acid (SCFA) metabolism has not been studied in subjects suffering from COPD. The purpose of this study is to compare the SCFA metabolism in COPD patients to healthy matched controls. This protocol is an extension of recent studies about protein digestion and absorption abnormalities in COPD patients. The investigators hypothesize that SCFA production might be lower in COPD patients than in healthy subjects.
