Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The feasibility study will involve mixed methods, this means interviews as well as assessment of treatment with inspiratory muscle training therapy (IMT). There are two pathways within the study depending on whether people want to have inspiratory muscle training. People who accept to have inspiratory muscle training will have assessments before training, after 8 weeks of training and at 6 month follow up in addition to interviews before and after the study (at 6 months). For those who choose not to have the inspiratory muscle training the investigators will offer them an interview so that the investigators can find out more about what might have made the study more appealing or what treatments they would have preferred. The investigators will also ask if they wish to be followed up with baseline assessments for the study period and if the investigators can access health records. Interviews Semi-structured interviews lasting approximately an hour will be performed at the beginning of the study with participants who accept the IMT pathway and those who decline IMT until no knew themes are raised. These interviews will be used to provide information on reasons for declining pulmonary rehabilitation, attitudes to exercise, attitudes to IMT, treatment preferences and opinions regarding study design and outcome measures (see Interview Topic guide). The interviews will be taped and transcribed verbatim. A follow up interview with study participants who have received IMT will be conducted at 6 months addressing attitudes to IMT and study design and whether they have decided that they wish to engage with other services (such as pulmonary rehabilitation and smoking cessation). Inspiratory Muscle Training (IMT) method Participants will perform 8 weeks of IMT strength training using the Powerbreathe Kinetic device (Powerbreathe). Training will progress to 60% maximum inspiratory pressure (PiMax). This means that each breath in through the device is set at 60% of the maximum force you are able to create when you breathe in rather than at full force. 30 breaths are performed at high velocity (paced initially over a period of 15 minutes to allow recovery between each breath through the device). Once established it is anticipated that each training session should take no more than five minutes. Training is performed twice a day, 5 days per week for the first 8 weeks. Training will be titrated (set to a level suitable for the participant) and supervised weekly for the first 8 weeks by a physiotherapist. After 8 weeks training the participants are advised to continue training unsupervised, twice a day, 3 times per week for a further 18 weeks.

The purpose of this study was to evaluate the effects of telemedicine video-consultation (TVC) on the frequency of hospital re-admissions during 12 months follow-up after TVC among patients with chronic obstructive pulmonary disease (COPD). Our secondary aims were to assess the impact of TVC on the length of recurrent hospital stays and time to re-admission within 12 months follow-up after TVC. We also wanted to evaluate the patient satisfaction related to TVC.

The main aim of pulmonary rehabilitation is to improve the quality of life of patients that have been diagnosed with chronic lung disease. The challenge for pulmonary rehabilitation is that many patients do not complete their agreed or prescribed training targets which may be related to the way pulmonary rehabilitation is delivered. There is a belief among doctors and other healthcare professionals delivering pulmonary rehabilitation care that patients who are working together as part of a group may better accomplish their agreed training targets (intervention). The intervention aims to encourage members of the group to interact and support each other during the rehabilitation sessions in order to attain agreed pulmonary rehabilitation goals

The objective of this study is to investigate molecular, cytological and genetic features of occupational chronic obstructive pulmonary disease (COPD) in conditions of different occupational exposures. In order to achieve this goal serum pro-inflammatory cytokines and standard inflammation markers level, hemostasis, cytological analysis of bronchoalveolar lavage and associations of single nucleotide polymorphisms (SNPs) rs1800470 transforming growing factor β1 (TGF β1) gene, rs1828591 hedgehog interacting protein (HHIP) gene, rs4129267 interleukin 6 receptor (IL-6R) gene, rs1051730 nicotinic acetylcholine receptor 3 (CHRNA3) gene with COPD in subjects exposed to silica dust and in those exposed to polycyclic aromatic hydrocarbons exhaust will be investigated. The relationship between genotype and phenotype characteristics, such as an inflammation activity, assessed by C-reactive protein (hsCRP) and tumor necrosis factor-α (TNF α) serum concentration, in different occupational COPD groups will be studied. The hypothesis is that the mechanisms underlying disease development and progression are different due to environmental risk factor that reflex in differs in disease attributes - molecular biomarkers, cytology results and genetic susceptibility between COPD due to dust, COPD due to chemicals and COPD in smokers therefore COPD can be subdivided into ecological phenotypes according to environmental risk factor.

The current definition of chronic obstructive pulmonary disease (COPD) is based on the presence of persistent airflow obstruction assessed by spirometry. About half of the subjects with mild COPD (i.e. reduced forced expiratory volume in one second (FEV1) on forced vital capacity (FVC) ratio along with normal FEV1] are asymptomatic. Subjects with symptomatic mild COPD have reduced exercise tolerance and abnormal dynamic ventilatory mechanics compared to healthy subjects. The physiological and perceptual responses to exercise of subjects with asymptomatic mild COPD are currently unknown. The purpose of this study is to assess exercise tolerance, ventilatory constraints on tidal volume expansion and dyspnoea in asymptomatic mild COPD subjects undergoing incremental cycle cardiopulmonary exercise testing (CPET) to the limit of tolerance compared with symptomatic mild COPD and healthy controls.
