Filter by:In this study, patients with Chronic Obstructive Pulmonary Diseases (COPD) in stable and acute exacerbation stage were selected as the research objects, and the open, parallel and randomized controlled clinical trial design was adopted. Participants were randomly divided into trial group and control group. The control group was only given routine education, and the experimental group, on the basis of routine education, developed a respiratory rehabilitation training program lasting for 12 weeks according to the individual situation of patients. All participants were interviewed for 6 times (baseline and 4,8,12 weeks, 6 months and 12 months after admission) for a period of 1 year. Acute exacerbation, activity tolerance (6-minute walking test), living environment, clinical symptoms, lung function, airway inflammation water level index and biological samples were collected at each visit. At the same time, according to the diary filled in by the patients, the investigators can obtain the daily stay time indoors and outdoors and the longitude and latitude information of the regular stay fixed place, and geographic information system (GIS) is used to match the nearest environmental monitoring station, obtain the data of air pollutants and meteorological indicators (SO2, NO2, Co, O3, PM10, temperature and humidity, etc.), and estimate the individual exposure level of air pollutants.
In the UK, field-based walking is prescribed in the pulmonary rehabilitation (PR) setting as a convenient, less resource-intensive, and highly responsive exercise modality in COPD patients. However, endurance time during the implementation of field-based walking protocols, such as the endurance shuttle walking (ESW) protocol, is limited to only a few minutes secondary to intense exertional symptoms. It therefore seems sensible to develop an intermittent field-based walking protocol that would prolong endurance time and walking distance compared to the commonly implemented in the PR setting continuous ESW protocol. The aim of this study is three-fold: 1) to identify whether an intermittent shuttle walking protocol significantly prolongs walking distance compared to the widely implemented continuous ESW protocol in the PR setting in patients with advanced COPD; 2) to investigate the test re-test reliability of the distance walked during the intermittent shuttle walking protocol; and 3) to explore patients' and health care professionals' experiences of implementing the intermittent walking protocol and the perceived factors affecting the implementation of these protocols in the PR setting. The study hypothesis is that the intermittent shuttle walking protocol would be associated with lower dynamic hyperinflation and breathlessness, thereby facilitating an increase in walking distance compared to the continuous ESW protocol. The same group of patients with advanced COPD will initially perform an incremental shuttle walk test (ISWT) (visit 1) to establish peak walking speed and subsequently patients will perform the continuous ESW protocol (visit 2) at a walking speed corresponding to 85% of peak walking speed to the limit of tolerance. On two additional visits (visits 3 and 4) patients will perform two intermittent shuttle walking protocols to the limit of tolerance by alternating 1-min walking bouts at a walking speed corresponding to 85% peak walking speed (equivalent to the ESW protocol) with 1-min rest periods in between walking bouts to establish the reproducibility of this protocol. Focus group interviews with patients and healthcare professionals will be conducted to explore perceptions of undertaking and implementing, respectively the intermittent walking protocol.
This is a multi-center, observational registry study involving secondary and tertiary hospitals across China. The objective is to study the disease burden, disease progression, comorbidities, treatment pattern and real-world cost, effectiveness and safety of different therapy options for COPD patients in Chinese clinical practice in China.
The main objective of this study is to assess the effects of a myofascial release protocol in patients with chronic obstructive pulmonary disease (COPD).
Chronic Obstructive Pulmonary Disease (COPD), , secondary to smoking, is a major public health issue with very high direct and indirect costs. The impact on the health system of undiagnosed patients, up to 70% of patients, is increasingly documented. However, systematic spirometry screening remains controversial among smokers in the absence of data to link the detection of new patients with improved management and clinical events and health goals. More generally, there is little data on the evolution of patients in real life once they have entered the care system. The premise is that with systematic screening in general medicine, it is possible to identify the evolution of newly diagnosed COPD patients, to distinguish the different possible evolutions according to the initial phenotype and the management.
Although some important progresses were made in the field of the meridian research, no breakthroughs have been achieved. Besides,there are some problems in meridian researches. The majority of the existing studies involve lots of subjective assessments for meridian phenomena. In addition, few studies have investigated the site specificity between two specific meridians.Therefore, this study is designed to detect the microcirculatory characteristics of meridian phenomena by using an objective assessment tool and investigate the site specificity for the meridian-visceral association and surface-surface association between two specific meridians.
It is a phase IV, prospective, interventional, single blind, randomized, crossover trial in which the investigators will evaluate the effects of a 4-week treatment with doxofylline 400 mg bid, in add-on to maximal inhalation therapy, in clinically stable COPD patients.
Prospective, sham controlled, interventional study to evaluate the extent to which PulseHaler improves the functional status of Chronic Obstructive Lung Disease (GOLD) II-IV Chronic obstructive pulmonary disease (COPD) patients.
Chronic Obstructive Pulmonary Disease (COPD) is a lung disorder commonly caused by smoking, which makes breathing more difficult. When COPD patients exercise, they are not efficient breathers and this leads to serious breathing difficulties, which often causes these patients to stop exercise at low intensities. Even though patients with a mild form of COPD have relatively well preserved lung function, they still have inefficient breathing during exercise. The investigators think that these individuals have problems exchanging fresh gas (i.e., oxygen) into the blood stream because of poor lung blood vessel function. The investigators will test whether inhaled medications, specifically nitric oxide, can improve lung blood vessel function and decrease breathing difficulties during exercise. With this research, the investigators will understand more about breathing efficiency and lung blood vessel function in individuals with mild COPD, and find out whether improving lung blood vessel function helps COPD patients breathe easier and exercise longer. Understanding the reasons behind the feeling of difficult breathing may lead to more effective therapy and improved quality of life in COPD patients.
Patients will be recruited during a routine consultation with a physician in the hepato-gastroenterology department. At the end of the consultation, patients will have to complete the following questionnaire: "European Community Respiratory Health Survey" which allows the screening of patients at risk of chronic respiratory diseases (asthma, COPD, bronchiectasis, emphysema). In the event of a declaration of functional respiratory signs, a consultation with a pulmonologist will be systematically proposed. At the end of this consultation, if the doctor deems it necessary, further investigations will be proposed and/or regular follow-up organised. The main objective of this study is to estimate the prevalence of respiratory symptoms leading to a diagnosis of chronic respiratory disease in patients with inflammatory bowel diseases (IBD) (Crohn's disease and UC). The main criterion for judgement will be the frequency of functional respiratory signs (wheezing, dyspnea, cough, sputum) reported by IBD patients through an adapted self-report questionnaire.
