According to World Health Organization (WHO), non-communicable diseases account for 70% of global mortality. Chronic Respiratory Disease (CRD) affects more than one billion people and is the third leading cause of annual death of five million people after cardiovascular disease and cancer. Asthma and chronic obstructive pulmonary disease (COPD) are the two most common diseases of CRD and are part of obstructive airway disease (OAD). Asthma and COPD are distinguished by the clinical manifestations and therapeutic strategy according to Global Initiative for Asthma (GINA) and Global Initiative for Chronic Obstructive Lung Disease (GOLD). However, in Vietnam, most patients with OAD are treated with an inhaled corticosteroid (ICS) combined with a long-lasting bronchodilator because the specific diagnosis is not always possible. In addition, a significant proportion of patients have clinical features of both asthma and COPD that is defined as the asthma COPD overlap (ACO). The definition of ACO remains controversial because it is not a distinct disease in which their specific treatment is still under debate that ICS is being generally proposed. It is understood that most OAD in Vietnam is treated with ICS. However, it is now accepted that in COPD (or COPD-like ACO) patients receiving this treatment may promote respiratory infections and even tuberculosis in endemic countries including Vietnam. Few data on the relative prevalence of asthma, COPD, and ACO are available in Vietnam. A recent study in Vietnam proposed defining asthma, COPD and ACO based on symptoms, ventilatory obstruction and bronchodilator (BD) reversibility, cumulative smoking, and age. Mites sensitization and exposure to biomass fume were then evaluated in patients having ACO. By doing so, COPD patients are smoking (≥ 10 pack-years) and have irreversible bronchial obstruction. Asthmatics are those with completely reversible bronchial obstruction OR non-smoking patients (<10 pack-years) and partially reversible obstructive. The other OAD patients were classified as having "ACO". Based on these definitions, the prevalence of COPD, asthma and ACO was 40%, 18% and 42%, respectively. Then ACO was defined as "from COPD, or ACO-COPD" in case of biomass exposure and negative mite skin tests, the others being ACO "from asthma or ACO-asthma". Currently, several biomarkers have been evaluated in the differential diagnosis and prognosis of OAD. The concentration of immunoglobulin E (IgE), the number of eosinophils in blood and sputum, nitric oxide (NO) in exhaled air, and recently periostin have been associated with asthma. On the other hand, biomarkers of systemic inflammation (C-reactive protein (CRP), fibrinogen, TNFα, IL-6 and IL-8) have also been investigated in COPD. Few data are available on the ACO biomarkers. In this study, the investigators will define the different phenotypes of chronic OAD (asthma, ACO-asthma, ACO-COPD and COPD) taking into account the reversibility of bronchial obstruction, cumulative smoking, biomass fume exposure and immediate sensitization to mites. Blood biomarkers and exhaled NO will be measured and analyzed in each phenotype. The treatment of COPD, asthma, ACO-COPD, and ACO-asthma based on the GINA and GOLD recommendations will be compared to the current practice in Vietnam: use of ICS with or without long-acting beta-agonists (LABA). Specific biomarkers will also be evaluated as predictors of treatment response.
Chronic obstructive pulmonary disease (COPD) is a common disorder that affects approximately 400,000 Danish citizens. About 3,000-3,500 Danes die yearly because of the disorder, and the costs associated with hospital admissions are estimated to be 535 million Danish kroner (DKK). Patients with COPD risk a worsening of their disorder, and in most cases, this will require hospitalization. One of the used treatments is providing oxygen to the patients via e.g. masks. The recommendations on oxygen treatment are currently based on a study from 2010 where 37% of the participants in this study did not receive the intended treatment, which may have had massive effects on the results. It is worrying that no other studies have shown which oxygen treatment is safest for the patients. As such, we deem it important to study how best to treat the patients. Our study is of high clinical relevance as hospitals receive patients with worsening of COPD daily. We need more, better data regarding the oxygen treatment of our patients, in order to provide our patients with the best possible care. The purpose of our study is thus to determine which oxygen treatment is best for patients with acute worsening of COPD symptoms. We will use a prospective, randomized controlled open-label trial. We will use two treatments: Treatment 1 is giving oxygen to the patient to reach a peripheral oxygen saturation of above 94%. Treatment 2 is giving oxygen to reach a peripheral oxygen saturation of between 88% and 92%. Our primary outcome is 30-day all-cause mortality, with secondary outcomes being 7-day all-cause mortality, need for non-invasive ventilation, intubation or intensive care admission, over-all length of hospital stay and respiratory acidosis. We believe that a lower oxygen saturation percentage may be superior as one study (Austin et al., 2010) showed a lower mortality rate in the group of patients that had a lower peripheral oxygen saturation. Additionally, the risk of respiratory acidosis and hypercapnia were lower. We wish to perform our study in the hospital sector as this study was performed in the prehospital sector and thus their results cannot be translated directly.
Discomfort during respiratory decompensation of a patient with chronic obstructive pulmonary disease (COPD) and/or obesity with a BMI greater than 30, in intensive care and the establishment of non-invasive ventilation (NIV) is frequent and a source of failure. this therapy. Pharmacological treatments may be impossible due to the pathology, the risk of it worsening and adverse effects. In this context, hypnosis appears to be a tool that would promote comfort and thus increase tolerance of NIV.
People with chronic obstructive pulmonary disease (COPD) experience distressing breathlessness and high health care utilisation. There is compelling evidence that pulmonary rehabilitation improves symptoms and reduces hospitalisation, but is delivered to <10% of patients who would benefit. The investigators developed a low cost model of pulmonary rehabilitation that can be delivered entirely at home. The HomeBase model had equivalent outcomes to centre-based pulmonary rehabilitation in a phase II efficacy trial, with higher completion rates. The investigators hypothesise that a patient centred model offering a choice between home or centre-based pulmonary rehabilitation may increase program completion rates, with improved outcomes for patients and the health system. This is a cluster randomised implementation trial investigating whether offering a choice of home or centre-based pulmonary rehabilitation can reduce hospitalisation, improve pulmonary rehabilitation completion and enhance patient outcomes in people with COPD. 14 pulmonary rehabilitation programs located across Australia will each recruit 35 people with COPD. Intervention centres: People with COPD will be offered the choice of centre-based pulmonary rehabilitation or the HomeBase model. Comparison centres: Only the existing centre-based model will be offered. The primary outcome is all cause, non-elective hospitalisation at 12 months. Other outcomes are symptoms, exercise capacity and quality of life at 8 weeks and 12 months; and health care costs at 12 months for full economic evaluation.
The onset and offset of the neural inspiratory time are fundamentally important measurements in studies of patientventilator interaction, where the level of assistance delivered by the ventilator is controlled by the patient's demand. The onset of neural inspiratory time can be determined in esophageal pressure, transdiaphragmatic pressure, and EMG signals. The investigator compare the onset measured by EMG, esophageal and transdiaphragmatic pressure, and consider that the correlation between them is well in different conditions.
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the World since 2003. Many people suffer from this disease or its complications for many years and die prematurely. In the European Union, the total direct costs of respiratory diseases are estimated to be around 6% of the total healthcare budget, with COPD accounting for 56% (38.6 billion Euros) of the costs of respiratory diseases. In the natural history of COPD, many patients may experience acute exacerbations (AECOPD) that are described as episodes of sustained worsening of the respiratory symptoms that result in additional therapy. These episodes of exacerbation that often require been seen in the emergency department and/or a hospital admission are associated with significant morbidity and mortality; they are responsible for a significant portion of the economic burden of the disease too. The pharmacological approach used in the management of AECOPD (inhaled bronchodilators, corticosteroids, and antibiotics), has the objective to minimize the negative impact of the current exacerbation and to prevent subsequent events. Despite the collaborative effort between the European Respiratory Society, the American Thoracic Society, and others to provide clinical recommendations for the prevention of AECOPD, there is still a considerable number of patients that are prone to suffer from recurrent exacerbations and to experience a more severe impairment in health status. Based on all the above, the aim is to identify the factors potentially associated with hospital admission in patients with AECOPD in English, French, German, and Spanish, speaking countries, and to develop a predictive model that predicts the risk of hospitalization in this group of patients, by using artificial intelligence. In this study proposes to take advantage of SAVANA, a new clinical platform, created in the context of the era of electronic medical records (EMRs), to analyse the information included in the electronic medical files (i.e., big data). This clinical platform is a powerful free-text analysis engine, capable of meaningfully interpreting the contents of the EMRs, regardless of the management system in which they operate. In this context, this machine learning analytical method can be used to build a flexible, customized and automated predictive model using the information available in EMRs.
Background: Chronic Obstructive Pulmonary (COPD) patients are the paradigm of the chronic complex patient. Their follow up can sometimes be difficult and challenging (1). There are patients with recurrent exacerbations that put an enormous burden on health care resources (2). They also have multiple comorbidities (3) that can sometimes make their management difficult. In an attempt to coordinate all these efforts KGH, HDH and Providence Care have numerous essential resources to take care of COPD patients like the nurse navigators, nurse practitioners and the pulmonary rehabilitation program. These programs provide an excellent support to the clinical activity of Respirologists and other health care providers. Rationale: The main rationale for the development of the Kingston COPD cohort is to translate that highly demanding clinical activity in a teaching and research oriented activity that could be used by clinicians, medical students, residents and fellows. Having a guideline complained established protocol in COPD patients that are usually follow at KGH and HDH could help in not only in unified the way COPD patients are seeing (preserving the importance of the personalized approach) but most importantly established a multidimensional (clinical, physiological, radiological, laboratory) database. This could help know not only the results of our clinical activity but also have a long term (>5yrs) database for clinical research projects in collaboration with national and international research groups. Therefore this proposal is important because it will help translate our busy daily clinical work in a highly productive teaching and research activity.
The ANM is the first initiative that puts advanced pharmaceutical care into practice in Andalusia (Spain). The aim of this is study is to evaluate the effectiveness of the intervention Assistance to New Medicines (ANM) in the improvement of adherence to treatment in community pharmacies.
Chronic obstructive pulmonary disease (COPD) is known as progressive lung disease and the fourth leading cause of death worldwide. Despite valuable efforts, there is still no Individualized accurate diagnostic and prognostic tool for COPD. Hence, the investigators' research integrated multi-dimensional data of COPD patients, which may provide an invaluable bioinformatic resource for understanding the underlying molecular alterations that drive disease progression, with the goal of developing individualized accurate diagnostic and therapeutic inventions.
