Filter by:HRCT was used to evaluate pulmonary vascular remodeling in COPD. The role of H2S in pulmonary vascular remodeling in COPD was analyzed, in order to provide a basis for seeking new therapeutic targets.
Design: this pilot-study uses a two-group random assignment pretest-posttest design. Once the groups are being selected an envelope will be mailed to the participant with the printed version of the exercise program and surveys, a portable SpiroBank Smart FN multi parameter spirometer (MIR), a finger pulse oximeter (LOOKEE), a diary, and a prepaid envelop for a subsequent post-intervention return of the equipment and surveys and the diary. Intervention: A) Exercise program: evidence-based and user friendly educational materials with recommendations on breathing and physical exercises will be developed. B) Patients intake: in a zoom meeting, a registered therapist (Pl) in charge of implementing the intervention will request informed consent to participate in the study, explain specifics of the intervention to each participant, and will conduct an initial assessment. C) Intervention (8 weeks): using the participants' initial assessment and personal characteristics, the therapist will provide personalized recommendations (e.g. maximum heart rate, minimum Sp02), explain the educational materials, and instruct patients on safety precautions (how to pace themselves, when to seek professional or emergency care). All participants (and immediate caregiver I necessary) will receive training: 1) basic device management (join a zoom meeting, watch a YouTube video), 2) use of the portable spirometer and its associated app, 3) use of finger pulse oximeter and 4) recording of the values in a dairy. Group one: will be asked to follow the exercise program with a small group of peers (2 groups/6 participants each) in a zoom meeting 3 times a week/45 min each {including 5 min before and 10 min after the meeting for free talk-chat between the participants e.g. questions, perceptions, etc.). The therapist will lead the first three meetings, gradually encourage participants to take turns leading the exercises with the goal of identifying /empowering potential patient leaders. Beginning with the fourth meeting, participants will be encouraged to connect to the meeting and follow their exercise program on their own, taking into account their individualized recommendations. The RA will organize and attend the zoom meetings to resolve general questions (e.g. equipment, platforms, etc.) and will act as a direct point of contact between the therapist and the participants. Group two: will be asked to follow the exercise program 3 times a week/30 min each while watching a pre-recorded YouTube video. D) Self-monitoring: patients will be asked to wear the finger pulse oximeter at all times while exercising, so that they can control their pace while avoiding exceeding target values (HR, Sp02). They will be asked to record in their HR and Sp02 values before and after participation in every session of the exercise program in a diary. E) Support: participants will be able to contact the therapist at any time during the study if they have questions or concerns. Otherwise, they will receive a follow-up phone call once a week from the RA.
This study uses a new breathing device called 'N-Tidal C' handset which measures breathing patterns. Investigators have found that people with cardiac and respiratory illnesses breathe out a gas, called carbon dioxide (CO2), in a different way to healthy people. The pattern of breathed out CO2 (the waveform) varies according to the underlying health of the user's lungs. Monitoring these changes may help doctors to more accurately diagnose and monitor the most common and serious respiratory conditions.
Observational, cross-sectional study with retrospective data collection from medical records. During the cross-sectional study visit, data will be captured through the use of electronic Case Report Forms (eCRFs). As there will be only one study visit, no prospective data collection will take place, nor collection of data that are not part of the routine clinic visit. For understanding the burden of severe exacerbations of COPD and the association between frequency of severe exacerbations and clinical and health-care utilization outcomes in less well-resourced countries
The primary objectives of the study are to use US and UK data to describe the characteristics of Chronic Obstructive Pulmonary Disease (COPD) patients according to various demographic, lifestyle, clinical, and medication use.
This study will evaluate safety and efficacy of FF/UMEC/VI via ELLIPTA® inhaler. ELLIPTA is a registered trademark of GlaxoSmithKline group of companies.
Develop appropriate individual programs for patients to implement lung rehabilitation safely and effectively.
Whole-body plethysmography (WBP) is the gold standard for measuring lung volume, but its clinical application is limited because it requires expensive equipment and is complicated to use. Studies have shown that the single-breath helium dilution (SBHD) method, which is commonly used in clinical practice, significantly underestimates lung volume in patients with obstructive lung disease (OLD). Therefore, by comparing the differences in lung volume measured by the SBHD method and WBP in patients with different severities of obstructive lung disease, we aim to establish a correction equation for the SBHD method to determine the total lung volume in obstructive lung disease patients.
In preparation for a future mechanistic study, investigators now propose to test the specific hypothesis that carnitine consumption is not reduced in PAH, that plasma carnitine levels are stable over time in PAH and that carnitine supplementation in PAH can increase plasma carnitine and thereby delivery of carnitine to the RV and possibly improve RV function. Investigators propose three aims in humans to test this mechanistic hypothesis, 1) Measure the oral consumption of carnitine in human PAH. This aim will use food diaries and carnitine supplement use questionnaires in PAH patients to test the hypothesis that carnitine supplementation is uncommon in PAH and food consumption is adequate. Aim 2) Measure the stability over time in plasma carnitine levels in PAH patients. This aim will test the hypothesis that plasma carnitine is not affected by disease severity and is stable over time in PAH patients. Investigators will measure plasma carnitine concentration and markers of fatty acid oxidation at Visit 1 and Visit 2. 3) Perform a mechanistic pilot study using carnitine supplementation to enhance circulating carnitine in PAH. This small pilot study will test the hypothesis that carnitine supplementation increases plasma carnitine (primary endpoint) and will test for physiologic effects using six minute walk testing, echocardiography and plasma markers of lipid metabolism.
This is a Phase 2 study in patients with chronic obstructive pulmonary disease (COPD) to assess the efficacy, pharmacodynamics (PD), pharmacokinetics (PK), and safety of two dose levels of CSJ117 in comparison to placebo. For this, the impact of CSJ117 on disease symptom burden and lung function will be explored.
