This study is planned to be conducted based on the cohort of patients with severe chronic obstructive pulmonary disease in our hospital. Based on gut microbiota, random forest was used to search for potential diagnostic biomarkers in patients with frequent acute exacerbation and controls with non frequent acute exacerbation; Construct a frequent acute exacerbation risk prediction model using random forest, support vector machine, and BP neural network models. The development of this study will provide valuable references for the clinical classification and prognosis evaluation of chronic obstructive pulmonary disease (COPD), and improve the health level of COPD patients by further searching for treatable targets.
Chronic obstructive pulmonary disease is a common disease worldwide. Pulmonary rehabilitation is an important part to decrease the complications of COPD. Blow bottle technique is an economical and subjective technique promote the lung expansion, as compare to ACBTs. It used to treat the different complications in COPD patients and also decrease the dependency of patient. To find the comparative effects of blow bottle and active cycle of breathing on sputum diary, oxygen saturation, pulmonary function and quality of life among the patients of chronic bronchitis. A randomized clinical trial will be conducted at Gulab Devi hospital Lahore. Through convenient sampling technique on 56 patients, allocated through simple random sampling through computer generated technique into group A and Group B. Group A will be treated with blow bottle technique and group B will be treated by with ACBTs. Pretreatment values will be recorded for BCSS for sputum, pulse oximeter, pulmonary function test and st. George for quality of life will be assessed before and after 8 weeks of the treatment. Data will be analyzed using SPSS software version 25. After assessing normality of data by Shapiro-Wilk test, it will be decided either parametric or non-parametric test will be use within a group or between two groups.
The goals of this observational study are to identify factors independently associated with admission eosinopenia in patients with a severe exacerbation of chronic obstructive pulmonary disease (COPD) and to determine when blood eosinophil count (BEC) will recover to baseline stable state in patients who are admitted to hospital with a severe exacerbation of COPD and associated eosinopenia. The main aims of the study are to: 1. Identify demographic, physiological and clinical factors independently associated with admission eosinopenia in patients with a severe exacerbation of COPD 2. Assess the time to recovery from eosinopenia to stable BEC following a severe exacerbation of COPD
Chronic obstructive pulmonary disease (COPD) affects 3.5 million people and is the third leading cause of death worldwide. Emphysema involves air retention in the lungs and is ultimately responsible for a major deterioration in the quality of life. Available drug treatments have moderate efficacy whereas surgical lung volume reduction can improve exercise capacity when offered to a very selected population but at the cost of significant morbidity and mortality. Endoscopic Lung Volume reduction with ZEPHYR® valves improves respiratory function at rest, exercise tolerance and quality of life in patients with little or no interlobar collateral ventilation. If this technique has therefore proven its effectiveness, it is not devoid of complications and is notably responsible for pneumothorax in 27% of cases. The management of this complication is clearly codified, ranging from patient monitoring to the removal of one or more valves. It is therefore a subject of major concern for multiple reasons: high incidence, lengthening of hospital stay, increase in the overall cost of care, potential loss of benefit for the patient in the event of permanent withdrawal. valves and above all a potentially fatal event. A new strategy for implanting ZEPHYR® valves in two stages has been developed in Limoges University Hospital. This innovative algorithm has been evaluated in several non-comparative single or multicenter studies. In those studies, pneumothorax' rate secondary to lung volume reduction with endobronchial valves is rated between 4.5 and 12%. The efficacy of the treatment appears to be comparable with the data found in the trials evaluating in which the entire lobe was treated in one procedure. Moreover, despite two procedures, there does not seem to be any increased risk of occurrence of other complications. Finally, the systematic scheduling of a thoracic computed tomography between the two procedures showed that 26.6% of patients presented a reduction in volume greater than 350mL despite incomplete treatment. These data seem promising but no direct comparison with standard one-step treatment has ever been conducted so far.

Chronic respiratory diseases are a global burden. Treatment options have improved in recent years, pulmonary rehabilitation plays a key role. Oxygen therapy is recommended in patients with a low saturation at rest, but no clear guidance is given for patients who desaturate during exercise. The effect of ambulatory oxygen during exercise is not yet completely understood, especially in those patients with exercise-induced desaturation. Aim: The goal of this study is to analyse the effect of supplemental oxygen given during a constant work rate exercise test (CWRET) on a cycle ergometer compared to sham air. Methods: We plan to include 25 Patients respiratory patients undergoing pulmonary rehabilitation (male and female; aged >18 years; stable condition >3 weeks (e.g. no exacerbations); resting oxygen saturation (SpO2) ≥ 88%) with exercise induced hypoxemia defined by a fall in oxygen saturation by ≥ 4% during a 6-minute walking test. Patients will undergo an incremental exercise test with a ramp protocol (for evaluating the maximal workload) and two CWRET (75% of the maximal workload) with ambulatory oxygen or placebo (sham air) via standard nasal canula at a flow rate of 5l/min. Patients and assessors will be blinded. The difference endurance time of the CWRET with oxygen vs. sham air will be the primary outcome of this study. Data will be summarized by means (SD) and medians (quartiles) for normal and non-normal distributions. Effects of treatment will be evaluated by mean differences with 95% confidence intervals, T-tests or Wilcoxon matched pair tests as appropriate. A p-value threshold of <0.05 or a confidence interval not including zero will be considered as statistically significant. Analyses will be performed according to the intention to treat principle.
Chronic obstructive pulmonary disease (COPD) is a common and treatable disease characterized by progressive airflow limitation and tissue destruction. It is associated with structural lung changes due to chronic inflammation from prolonged exposure to noxious particles or gases most commonly cigarette smoke. POWERbreathe device (POWER-breathe International Ltd., Southam, Warwickshire, UK) is an inspiratory muscle training and this device has recently shown benefits on pulmonary function. Also, the POWER-breathe® device's effects on the strength of the diaphragm muscle and minimize muscle weakness and wasting in COPD patients. Neuromuscular electrical stimulation (NMES) is commonly used in physical therapy to increase muscle strength and promote muscle hypertrophy. NMES applied to respiratory rehabilitation is called transcutaneous electrical diaphragmatic stimulation (TEDS).
This work is a multicentric prospective cohort study designed to improve chronic obstructive pulmonary disease (COPD) treatment and management. The study involves 150 patients diagnosed with COPD who are at risk of exacerbations. These patients are recruited from three tertiary hospitals in Spain, Germany, and Italy. The study will last 18 months, with a 12-month follow-up duration for each patient. The primary objective of this study is to develop and test Artificial Intelligence (AI)-based models that can predict moderate-to-severe COPD exacerbations early on. This will be done by analyzing daily-life data collected from unobtrusive sensors that monitor patients' psycho-physiological and environmental signals. By accurately predicting exacerbations, the study aims to support clinicians in providing more precise, optimized, and personalized treatment to COPD patients. A secondary objective is to train and test AI-based models to estimate the 12-month dynamics of health-related quality of life (HRQoL) in COPD patients. This will involve analyzing data related to the patients' functional exercise capacity, dyspnea (difficulty breathing), and health-related quality of life, as measured by the Clinical COPD Questionnaire (CCQ) score and the COPD Assessment Test (CAT) score.
Chronic obstructive pulmonary disease (COPD) is a complex, heterogeneous disease usually with a decline lung function and worsening symptoms; hence, both forced expiratory volume in 1 s (FEV1; lung function) and validated patient-reported outcomes (PROs) are used in clinical trials to assess disease severity and response to treatment. The PROs are different in terms of their scope of assessment and in the information that they capture. PRO questionnaires such as the Baseline Dyspnoea Index (BDI), Transition Dyspnoea Index (TDI) and modified Medical Research Council (mMRC) dyspnoea scale are used to assess dyspnoea, whereas the Clinical COPD Questionnaire (CCQ), COPD Assessment Test (CAT) and St George's Respiratory Questionnaire (SGRQ) are commonly used to assess patients' health status . Furthermore, the mMRC scale is unidirectional and minimally responsive to treatment interventions, while the BDI, TDI, CAT, CCQ and SGRQ (approved by the USA Food and Drug Administration) are multidirectional.
