For patients admitted to the medical ward, it is often difficult to predict if their clinical condition will deteriorate, however subtle changes in vital signs are usually present 8 to 24 hours before a life-threatening event such as respiratory failure leading to ICU admission, or unanticipated cardiac arrest. Such adverse trends in clinical observations can be missed, misinterpreted or not appreciated as urgent. New continuous and wearable 24/7 clinical vital parameter monitoring systems offer a unique possibility to identify clinical deterioration before patients condition progress beyond the point-of-no-return, where adverse events are inevitable. The WARD-COPD project aims to determine the correlation between cardiopulmonary micro events and clinical adverse events during the first four days after hospital admission with acute exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD).
Chronic Obstructive Pulmonary Disease (COPD) is a common progressive lung disease which causes breathlessness and frequent exacerbations, with patients often requiring hospitalisation. Patients with severe COPD commonly become housebound and lose their independence. They have a higher symptom burden than those with incurable lung cancer, yet are less likely to receive specialist palliative care, or to have been engaged in advance care planning (where patients discuss and often document their wishes regarding their future care). Hospital admissions become increasingly common towards the end-of-life; therefore, hospitalisation is a good opportunity to identify patients at risk of poor outcome. Such patients may wish to consider alternatives to admission and avoid intrusive treatments. Unfortunately, predicting which patients are likely to die in the near future is challenging thus far. The first step required to improve provision of palliative care services, and ensure patients are given the opportunity to make truly informed decisions about their future care, is accurate identification of those most likely to benefit. Well-designed clinical (prognostic) tools outperform clinician judgement in most settings. The investigators will compare the accuracy of one year mortality prediction of several clinical tools in patients who survive a COPD exacerbation requiring admission. This will initially be performed using existing data collected during previous research (the 1,593 patient validation study for the PEARL score - Previous admissions, extended Medical Research Council Dyspnoea score, Age, Right and Left heart failure), then confirmed in at least 310 patients admitted uniquely and consecutively with an exacerbation of COPD. The latter group of patients will be invited to participate in a longitudinal follow-up study, assessing symptom burden, quality of life, and readmissions over one year.
The aim of this study is to assess the effectiveness of a home-based exercise training program in COPD patients who did not participate in an inpatient or outpatient rehabilitation program within the last 2 years.
This is a qualitative research exploration engaging clinical staff at all levels from 10 Practice-Based Research Networks (PBRNs) serving US patient populations of differing gender, racial, ethnic, urban/rural and socio-economic blends, in the incorporation of a one-page, five-item questionnaire with selective PEF measurement (CAPTURE).
A study to evaluate the effects of ACT-541468 on respiration in patients with moderate chronic obstructive pulmonary disease
This is a prospective multicenter cohort study which includes all consecutive COPD patients who come for a visit in one the participating pneumologist. They will have to do a sputum and to complete some questionnaries. Questionnaries will be redone by phone after 1 and 3 months and during the visit after 6 months. We will correlate aspergillus presence in sputum with quality of life (QoL), and COPD symptoms evaluated by questionnaires.
This study will evaluate the efficacy and safety data of AZD8871 in patients with moderate to severe chronic obstructive pulmonary disease (COPD). This study will determine the 24-hour efficacy (lung function) profile of AZD8871 600 μg relative to placebo dry powder inhaler (DPI) based on trough forced expiratory volume in 1 second (FEV1) following repeated dosing (2 weeks). Anoro® Ellipta® (umeclidinium/vilanterol) once daily is included as an active control. This study aims at providing a novel approach to the treatment of COPD with greater efficacy than single-mechanism bronchodilators, equivalent to long-acting muscarinic antagonist (LAMA) and long-acting β2-agonist (LABA) administered as free- or fixed-dose combination therapies, with an equivalent or superior safety and tolerability profile.
Respiratory rehabilitation is one of the main treatments for COPD in the early stages of the disease (Stage 2 of GOLD) with a recognized effect on improving the capacity of the patients to exert effort by fighting against deconditioning. the effort. This treatment also improves the quality of life of patients and reduces the risk of respiratory exacerbations. The patients are very often malnourished and various studies have proposed the addition of oral supplementation such as hormone therapy (testosterone) to improve the exercise performance of these atrophied muscles. The use of branched-chain amino acids (AARs) such as valine, leucine, isoleucine in this indication can be fully justified because they stimulate protein synthesis and promote muscle maintenance and repair.
Chronic obstructive pulmonary disease (COPD) is characterized by dyspnea, as well as musculoskeletal and systemic manifestations. Photobiomodulation therapy (PBMT) with use of low-level laser therapy (LLLT) and/or light emitting diode therapy (LEDT) is an electrophysical intervention that has been found to minimize or delay muscle fatigue. The aim of this study is to evaluate the acute effect of PBMT with combined use of lasers diodes, light emitting diodes (LEDs), on muscle performance, exercise tolerance and metabolic variables during the 6-minute stepper test (6MST) in patients with COPD. Twenty-one patients with COPD will completed the 6MST protocol over 2 weeks, with 1 session per week. PBMT or placebo (PL) will be performed before each 6MST (17 sites on each lower limb, with a dose of 30 J per site, using a cluster of 12 diodes: 4 × 905 nm super-pulsed laser diodes, 4 × 875 nm infrared LEDs, and 4 × 640 nm red LEDs; Multi Radiance Medical™, Solon - OH, USA). Patients will be randomized into two groups before the test according to the treatment they will receive. Assessments will be performed before the start of each protocol. The primary outcomes are oxygen uptake and number of steps, and the secondary outcome are perceived exertion (dyspnea and fatigue in the lower limbs).
