Active clinical trials for "Lung Diseases"

Fatigue is a prevalent symptom in Chronic Obstructive Pulmonary Disease (COPD) that limits patients in their daily living activities. It is now well established that COPD patients may have altered neuromuscular functions compared to healthy individuals. However, the different studies conducted on muscle fatigue in COPD have been done independently of any cognitive solicitation, yet present in most of daily living activities. Therefore, the aim of this research is to evaluate the impact of the disease on neuromuscular fatigue during dual-task situation (simultaneous accomplishment of a muscle contraction and a cognitive task). A better understanding of fatigue in COPD will promote the development of new perspectives in patient management. The hypothesis is that COPD patients will exhibit increased fatigue level (compared to healthy subjects), particularly during dual-task situation. It is assumed that the higher negative effect associated with the dual-task will be related to different neurophysiological mechanisms (i.e., neuromuscular fatigue, autonomic nervous system activity, mental fatigue).

Recruitment of patients with COPD. Assessment of clinical status, determination of vitamin D and cathelicidin levels. In the group with vitamin D deficiency, patients receive cholecalciferol (vitamin D) daily for 3 months. After 3 months, the clinical status was assessed again, the level of vitamin D and cathelicidin was determined. When vitamin D levels normalize, cholecalciferol replacement therapy is discontinued for 3 months. After that, a control inspection and laboratory tests are performed.

The current study recruited patients with fibrosing interstitial lung diseases (f-ILD) whatever was the underlying pathology. The investigators aimed to compare the effects of aerobic exercises for lower limbs (LL) versus upper limbs, lower limbs, and breathing exercises (ULB) on the peak exercise measurements that was measured using cardiopulmonary exercise testing (CPET), dyspnea and health related quality of life assessment in this group of patients.

Chronic Obstructive Pulmonary Disease (COPD) has a significant impact on one's quality and quantity of life resulting in increased morbidity and mortality. In Ireland, COPD has the highest hospital admissions in comparison to other countries within the organisation for economic cooperation and development (OECD). There is a need to improve knowledge and self-management behaviour in order to improve recognition of early signs of an exacerbation thereby seeking early treatment from the general practitioner (GP) thus reducing hospital admissions among this cohort . There are limited studies pertaining to the use of a comprehensive self-management programme via a smartphone app for people with COPD on a longitudinal basis.The aim of this study is to investigate the effectiveness of a smartphone application self-management programme on clinical health outcomes in patients with COPD.

This study evaluates the effects of KOL-webben (the COPD web), an interactive web-based system directed towards two target groups; people with chronic obstructive pulmonary disease (COPD) and health professionals in primary care. KOL-webben include tools that improve health literacy with a specific focus on 1) increased physical activity and 2) use of appropriate self-management strategies. Moreover, KOL-webben include knowledge and tools directed towards staff in the primary care aimed to implement provision of evidence based health promotion interventions.The feasibility and effects of KOL-webben will be evaluated.

The purpose of this randomized controlled trial was to evaluate the effects of a respiratory rehabilitation exercise training package on dyspnea, cough, exercise tolerance, and sputum expectoration of hospitalized elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Using purposive sampling, 61 participants were recruited and randomly assigned to either the experimental group (n = 30) or the control group (n = 31). The experimental group participants received the respiratory rehabilitation exercise training twice a day and 10-30 minutes per session for four days. The control group participants received usual care and health education. Data were collected at baseline and at the end of the four-day intervention.

The prevalence, low cost, and low burden of wearable devices that provide quantitative and qualitative feedback on a subject's activity level present an opportunity for the use of these devices in clinical and observational studies. However, the accuracy and reproducibility of any given device may vary with device design and algorithm implementation. Therefore, validation of emerging technologies against known standards such as analysis of exhaled breath and currently available medical devices is critical. This is a single center, two-cohort, single period, open-label, methodology study. No investigational product will be used in this study. Eligible subjects will wear 2 generations of SenseWear Armband devices, 2 ActiGraph GT9x devices (one on the wrist and one on the waist) and a Garmin Vivofit 2 activity tracker wristband for up to 24 hours per day. Subjects who consent to participate in an optional sub-study will wear a SOMNOwatch Plus EEG-6 device while sleeping. Subjects will perform a variety of laboratory and field-based exercise tests and strength exercises using Latex-Free Therabands.The co-primary objectives of this study are firstly to compare the outputs of the test devices (SenseWear Armband Gecko and Actigraph GT9x) to those of the SenseWear Armband MF and secondly to assess the sensitivity and accuracy of the test devices in subjects with COPD or asthma while performing laboratory-based exercise testing.

Among many other causes, Bronchial obstruction in Chronic Obstructive Pulmonary Disease (COPD) is also caused by inflammation of peripheral airways walls. Neutrophils and other inflammatory mediators like Interleukin-6 (IL6), Interleukin-8 (IL8), Interleukin-1 alpha (IL-1 alpha),Interleukin-1beta (IL-1 beta), Tumor Necrosis Factor alfa (TNF-alfa), Reactive Oxygen Species (ROS), Leukotriene B4 (LTB4), Nitric Oxyde (NO) are implicated in the inflammation. NO is produced in response to physical and chemical stress on bronchial epithelium and plays a critical role in small airways remodelling Exhaled NO concentration is usually used to monitor bronchial inflammation The relationship between stretch and strain of small airways and bronchial inflammation is not well understood. The investigators hypothesis is that cyclic opening and closure of peripheral obstructed airways through the consequent stretching and strain acting on them can provoke an inflammatory response which can be monitored by exhaled NO. The pharmacological effects of bronchodilators may play a role on bronchial inflammation by reducing the stretching stress on bronchiolar walls thus reducing the production of NO in exhalate Data about these physiopathological aspects is missing in literature.
