Active clinical trials for "Respiration Disorders"

This study aimed to evaluate the correlation between the point of care blood analysis obtained from skin puncture blood and conventional blood analysis obtained from venous and arterial blood.

Social distancing during the COVID-19 pandemic could lead to clinical and functional deterioration of people living with chronic respiratory diseases (CRD). As they are considered risk group for COVID-19, it is not recommended that they leave their house and have interaction with people outside. Thus, most of them have not been attend Pulmonary Rehabilitation sections since the beginning of pandemic, neither exercising outdoor, experiencing drastic restrictions in their activities of daily living. It is well known that low level of physical activity in daily life (PADL) in this population is related to poor prognosis, including higher chance of hospitalization due to exacerbation and mortality. Therefore, the aim of this study is to evaluate the short- and mid-term impact of the COVID-19 pandemic on the clinical, physical and functional conditions and the PADL level of people living with CRD (chronic obstructive pulmonary disease, asthma and interstitial lung diseases). Participants will be assessed during the social isolation period and they will be reassessed immediately after release from social isolation. Thus, the subjects will be followed-up during 12 months to record symptoms, functional status, quality of life, exacerbations and hospitalizations. The researchers' hypothesis is that those patients will present very low level of PADL in association to sedentarism, poor functional status, more symptoms of dyspnoea, anxiety and depression, poor sleep quality and, consequently, will present more episodes of acute exacerbation of the disease and more hospital admission during the study protocol.

The study aims at evaluating the AirGoTM system's performance, as compared to standard pulmonary function tests.

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.

30 patients acute hospitalized to medical ward and their medication records are examined. It is to be recorded how the investigators find information about medicine use by the reception when they do not follow the patient. The record of the changes made during hospital stay is examined, whether they are justified in the discharge summaries and whether they are described in the medical list. After a month is to find out if the GP has recorded or possibly rejected changes to medication made in hospital.

The Austrian LEAD study is the first investigation initiated in Austria that aims to investigate the prevalence and the natural history of COPD in a reference population of Austria.

Study the prevalence of the urinary incontinence among adults with respiratory diseases.

A cross-sectional study is expected to conducted by inquiring about the history, diagnosis results and medication details of respiratory diseases of the outpatient pediatric patients with respiratory diseases in the pediatric departments at specialist children's hospital at the second class and above, general hospitals and maternal and child healthcare hospitals. About 10,000 electronic questionnaires are expected to be collected in total, with about 100 participating hospitals and 100 electronic questionnaires from each participating hospital.Diagnosis and treatment information of pediatric patients are expected to be collected in the third week in April, July and October 2021 and in January 2022.

Chronic Respiratory Disease (CRD), particularly asthma and chronic obstructive pulmonary disorders (COPD) are leading causes of mortality and reduced quality of life due to its wide-reported association with other multi-morbidities.There is limited knowledge on the burden of CRD in the rural communities in Bangladesh due to poor awareness on the impact of CRD on quality of life and unavailability of diagnostic facilities due to weaker primary healthcare settings. The study aims to estimate the CRD burden in Bangladesh in a large representative population to draw the attention of policy makers to the creation of social awareness and improvement of primary healthcare infrastructure for respiratory disease in Bangladesh. The study is a prospective observational one in nature. The study will be implemented in Mirzapur, a rural sub-district of Tangail district in Bangladesh within the period of February to May 2021. A total of 981 participants will be enrolled from the study. Verbal consent will be taken initially. Participants who are assessed to be COVID-19 negative will be invited for a visit to the mobile clinic following national health guidelines to perform the spirometry. The study team will provide an information sheet (written in local language) that describes the study aim and objectives with potential risk benefits to the participants. All participants will be enrolled through written consent and satisfactory response to the patient information sheet. The Research Assistant (RA) will collect the relevant metadata such as demographics, information on risk factors, screening questionnaires relevant to asthma and COPD, reported health status and symptoms related to CRD etc. from the participant after obtaining the written consent. Data quality will be ensured by the Field Research Supervisor through checking all the collected information. The enrolled participants will undergo spirometry for the evaluation of their lung function. Spirometry will be collected by trained personnel and will be quality checked by an expert panel at CHRF. Repeated collection will take place in the event if the test results do not pass quality checking. Participant will also be invited to the study clinic within the next 10 days after assessment for any further clinical assessment that is deemed necessary by the study physician. The collected data and spirometry reports will be reviewed to evaluate the CRD patient in terms of their disease. The study will analyse the rate of CRD burden stratified by age, sex, and income group. The productivity loss will be measured in terms of work hours lost due to CRDs.

It is not yet known whether an analysis of daytime sleepiness over the course of the day can predict the diagnosis or severity of sleep apnea. The goal of the study is to examine whether a psychometric determination of daytime sleepiness can adequately and practicably record daytime sleepiness in patients with mainly sleep apnea in comparison to other standardized methods.
