Filter by:This study aims to evaluate simple tests of physical function in hospitalised patients with chronic obstructive pulmonary disease (COPD) and to assess whether they can predict future hospital readmission. The Short Physical Performance Battery (SPPB) is a simple test of standing balance, usual walking speed (4-metre gait speed) and ability to stand from a chair, which reflects global physical functioning and frailty. We hypothesise that the SPPB or 4-metre gait speed can predict future hospital readmissions.
Remote Health Monitoring (RHM) is the assessment of one's own symptoms at home between doctor visits, using things like at-home breathing tests, electronic diaries to answer questionnaires, and other monitoring devices. The hypothesis of this study is that the health and quality of life of people with COPD who do RHM for one year will be better than people with COPD who do not do RHM. Subjects who are at least 40 years old, have been diagnosed with chronic obstructive pulmonary disease (COPD), also known as chronic bronchitis or emphysema, and are current or former smokers will be invited to participate. This study is paid for by eResearch Technology (eRT). Subjects will complete 2 visits at UCLA, separated by one year of RHM. All subjects will participate in RHM. RHM will involve daily monitoring at home using a few electronic devices: blood oxygen levels, symptoms, medication use, breathing tests, and activity monitoring. Visits will include physical exam and medical history, ECG, questionnaires, breathing tests, and exercise tests.
The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.
Patients with advanced heterogeneous emphysema experience improvement in clinical outcomes in the same way following either implantation of endobronchial valves or intrabronchial valves.
The PneumRx Lung Volume Reduction Coil (LVRC) has been shown to effectively improve quality of life, exercise capacity, and static lung volumes, in patients with emphysema. The mechanism of action for these effects is believed to be related to the restoration of elastic recoil to lung parenchyma that has been damaged by emphysema. The objective of this study is to evaluate several physiologic parameters which should provide measures directly related to the mechanism of action by which the coils produce these outcomes.
The purpose of this study is to investigate the effect of endoscopic valve implantation in patients with COPD and PH on hemodynamics, symptoms, exercise tolerance and quality of life in 10 patients in a prospective study. An improvement of objective parameters may also have a prognostic significance
Aims: To prove the benefits of an specific strength training program in COPD patients compared to those achieved with the traditional endurance training. We will assess which is the proper training modality and which of them is the most beneficial according to the features of the patient to whom it is applied. Subjects and Methods: We will study 66 patients diagnosed of COPD with a moderate-severe obstruction (FEV1<60%) and clinically symptomatic. The monitoring will be done for 3 moths. Patients will be differentiated between COPD with "predominant chronic bronchitis" and COPD with "predominant emphysema", with regard to clinical, functional and radiological criteria. After stratification of the sample, patients will be prospectively assigned to three groups of 22 patients each: a) Endurance training group, on cycle ergometer at a workload of 70% VO2max. b) Strength training group, with 5 different weightlifting exercises (4 sets of 6-8 repetitions). c) Mixed training group, with half the time dedicated to each type of training. Training will be developed during 12 weeks, three times per week, in 40 minutes sessions. Analysed variables, at the beginning and at the end of program will be: Chest X-ray, basic blood analyses, electrocardiogram, simple spirometry and bronchodilator test, blood gases, static pulmonary volumes, diffusion measurement and respiratory muscle pressure. Muscle strength will be assessed by means of 1RM test and the Myometer® dynamometer. Using the muscle skeletal ultrasound, we will control changes in muscle fibre size. Maximal and submaximal exercise tests on cycle ergometer will be also performed, so as a walking test (shuttle walking test). At last, we will assess treatment effect on dyspnea (Mahler`s test) and quality of life (CRDQ). Hypothesis: A strength training program would significantly increase peripheral muscle power. This type of training would mainly have effect on the "predominant emphysema" COPD patient, where the important weight lost causes a decrease in muscle strength.
The objective of this study is to demonstrate the safety and performance of the PneumRx, Inc. Lung Volume Reduction Coil (LVRC) in a population of patients with emphysema. The PneumRx, Inc. LVRC is used as a less invasive alternative to lung volume reduction surgery.
This is a multicenter single arm open label study. The primary objective is to evaluate the safety and effectiveness of the Lung Volume Reduction Coil (LVRC) for the treatment of patients with emphysema in multiple centers.
HIV-infected patients have an increased incidence of emphysema compared to non-HIV-infected patients, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infections that amplifies the pulmonary inflammatory response. The investigators will examine the prevalence and progression of emphysema in subjects with and without HIV and determine risk factors for emphysema in this population.
