Filter by:This trial is a randomized, double-blind, parallel placebo clinical trial, the purpose of which is to investigate whether the adjuvant therapy of using probiotics during the treatment of diabetic patients can decrease blood sugar levels significantly in comparison with placebo, and observe if the reduced lung function could be recovered in patients with type 2 diabetes (T2DM) and chronic obstructive pulmonary disease (COPD) simultaneously.
The aim of pulmonary rehabilitation is to improve exercise capacity and reduce dyspnoea. As well as improving the patient's overall condition, pulmonary rehabilitation provides a means to monitor the patient regularly. During physical exercise, the increased activity of the muscle system increases cardiac and respiratory output. If the patient's respiratory status deteriorates, as occurs, for example, before the onset of an exacerbation, exercise capacity could be reasonably expected to reduce. The investigators hypothesised, therefore, that changes in the physical capacity of patients with COPD during a rehabilitation session could provide a predictive indication regarding the risk of occurrence of exacerbation.
The national COPD screening program is in a cross-sectional manner at the baseline, planning to recruit a total of 800,000 participants from 160 districts or counties (5,000 for each site on average) from 31 provinces, autonomous regions or municipalities directly under the central government of China. The filtered COPD high-risk population and confirmed COPD patients will be managed and followed up according to the standardized clinical guidelines. The major aims of the program are to estimate the prevalences of COPD high-risk population and under- or miss- diagnosed COPD patients, and to manage the development and outcomes of the disease.
Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease defined by permanent airway obstruction. In this disease, a large part of the muscular work is taken up by breathing (fight against bronchial, parietal or fibrous resistances of the pulmonary tissue, reduction of the exchange surface), requiring a physiotherapeutic care. Physiotherapy management of "respiratory rehabilitation" includes 4 items: respiratory therapy for decongestion, muscle strengthening, improvement of endurance and therapeutic education. In this context, the techniques of de-cluttering aim to decrease the hydrodynamic resistance of the bronchial tree. A systematic evaluation of the patient's condition is carried out by the practitioners to assess, at the time of the session, the bronchial congestion. In addition to their knowledge of the history of the patient they are following and the result of the oximetry measurement, practitioners use several indicators to assess the patient's bronchial congestion and define their therapeutic approach: cough, sputum, oximetry and peak expiratory flow, pulmonary auscultation. Sound expertise remains delicate: even the most educated human auditory system is not physiologically capable of detecting some of the relevant information. The current quantification criteria are therefore not very objective, depend on the practitioner's expertise and do not allow recommendations to be made on the conduct of the session during the follow-up of patients. Consequently, the objectification of bronchial congestion is clearly part of the process of improving management. In this context, the MUKROBS project seeks to objectify the bronchial congestion of COPD patients during their management by means of respiratory physiotherapy techniques of de-congestion by means of expiratory flow modulation techniques. The Sybille device, designed, developed and validated in the framework of a previous project funded by the ANR VirtualChest, allows continuous, non-invasive and simultaneous measurements of sound and displacement information at specific points of the thoracic cage.
Background : Long-term oxygen therapy is prescribed for patients with severe COPD. The aim of oxygen therapy is to administer oxygen at a concentration level higher than that of ambient air, in order to treat or prevent the symptoms and manifestations of arterial hypoxemia; this therapy can be applied either in an acute situation or as a long-term treatment, in cases of stabilized severe chronic hypoxemia. Currently, pneumologists do not have the possibility, between 2 consultations spaced several months apart, to measure the patient's compliance with the treatment (adherence to oxygen therapy) nor the respect of the prescribed dosage (O2 flow and duration). In addition to the patient's adherence to the treatment, the specialist does not have the possibility to assess the patient's physical activity (walking ...). This observational study is a e-health, prospective, multicenter study conducted in France under the control of pneumologists. The main objective of this study is to evaluate the adherence to oxygen therapy in real life, and its evolution, in COPD patients justifying a long term oxygen therapy in stable state.
Symptoms such as cough, wheeze, and breathlessness are among the most common reasons for general practitioner or emergency department visits in the UK. Such symptoms have a profound impact on patients' ability to live a fulfilled life, often rendering people unable to work and socialise. Azithromycin (a type of antibiotic) improves symptoms and reduces flare-ups of diseases such as asthma and chronic obstructive pulmonary disease (COPD). The reason why it works is unclear. Many people believe that it either decreases the number of bacteria in the lungs or reduces inflammation in the lungs and the upper airways. Neither theory is proven. Another possible mechanism that has been much less studied is that Azithromycin encourages the body to move food and fluid through the gut more quickly, thus preventing reflux and aspiration of small food particles and stomach acid. It has been shown that lung damage can occur when gut contents enter the airways, which may contribute chronic lung disease patients' symptoms In this study the investigators will test the effect of azithromycin on the gut in patients with chronic lung diseases. The investigators will measure the strength of a patients swallow by measuring the pressures in their gullet, using high-resolution oesophageal manometry (HROM), before and after treatment, in people being started on azithromycin as part of their routine care. The investigators will also measure the effect that azithromycin has on their symptoms and observe whether there is a relationship between the strength of their swallow and their symptoms. At the end of this study, the investigators hope to better understand the way in which azithromycin helps to improve the symptoms of patients with chronic lung diseases. The investigators also hope to open the door to investigate the effect of other drugs that improve gut function in patients with chronic lung diseases.
The aim of the study is to synthesize qualitative evidence related to preventable hospitalizations/ emergency department visits from the perspectives of patients, their families/caregivers, health care providers, and stakeholders, in the hope to identify generalizable conclusions about why social risk factors matter to preventable hospitalizations/ emergency department visits
The study is conducted in the context of the COVID-19 pandemic in general, and more specifically in the context of the evaluation of the use of protective masks as a barrier to the spread of the virus. The wearing of masks is one of the recommended barrier measures to limit the spread of the SARS-CoV-2 virus responsible for COVID-19. It is recommended in all circumstances, and mandatory in some. Regardless of the type of mask used (noting that the so-called "surgical" masks are by far the most common), there are various disadvantages associated with wearing them. Dyspnoea (unpleasant or upsetting perception of respiratory activity) is one of these disadvantages. It can lead to reluctance to wear the mask, or to the adoption of inappropriate practices that reduce its effectiveness. This "side effect" of the mask is more pronounced in patients with underlying respiratory diseases. However, not all mask designs are equivalent in terms of their physical properties, which can theoretically generate varying levels of dyspnoea. It is therefore important to determine which mask designs are more or less dyspnogenic, in order to guide the preferential use of certain designs in certain patient categories. The TOLMASK study (Tolerance of SARS-CoV2 Surgical Masks in Patients with Chronic Respiratory Diseases) is a prospective, randomised, triple-blind, single-centre study comparing several surgical masks in a crossover design. The primary objective of the study is to evaluate the respiratory tolerance of different surgical masks and the secondary objective is to evaluate their general tolerance.
Does an educational intervention for untreated COPD and cardiovascular disease which is integrated in an existing lung cancer screening program improve guideline concordant medication adherence at 12 months
COPD and non-COPD patients will be included in the study after collection of their non-objection. The exhalation will be collected to study the microbiological diversity of human exhalations. a second collection for the year +1 will be made, at the same time (between October and March).
