Active clinical trials for "Signs and Symptoms, Respiratory"

Recently integrated in clinical practice, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification states that a mild (stage I) chronic obstructive pulmonary disease (COPD) is present, in a smoker, when the postbronchodilator forced expired volume in 1 second (FEV1) to forced vital capacity (FVC) ratio is < 0.7. A major change that was introduced by the GOLD classification system was that COPD could be diagnosed despite an FEV1 that is within normal predicted values (above 80% predicted). Because it suggests diagnosing and detecting COPD earlier than done until very recently in medical practice, the GOLD standards bring in a new reality to clinicians. In fact, this novel COPD classification comes with new research challenges because the functional impacts and systemic consequences related to COPD are mostly documented in patients with moderate to severe stages with little information specifically in GOLD stage I COPD. This information is important if the investigators are to convince physicians that GOLD stage I COPD needs to be diagnosed and eventually treated. The investigators aimed to characterize GOLD stage I COPD patients according to activity-related dyspnea. More specifically, our objectives were to compare: i) baseline pulmonary function ii) exercise capacity iii) quadriceps muscle function iv) levels of physical activity in daily life between symptomatic (Sx) GOLD stage I COPD patients, asymptomatic (ASx) GOLD stage I COPD patients and healthy control subjects (CTRL). The investigators reasoned that exercise tolerance and physical activity levels would be decreased in Sx GOLD stage I COPD patients as it would be similar between ASx GOLD stage I COPD patients and CTRL.

Work related asthma and rhinitis are frequent diseases with a significant morbidity and a social and economic impact. Farmers are highly exposed to various inhaled agents such as organic or inorganic dust, endotoxin, micro-organisms, pollen, mites, moulds, animal danders and pesticides, inducing rhinitis, asthma, chronic bronchitis, hypersensitivity pneumonitis and organic dust toxic syndrome. Work related respiratory symptoms are frequent in crop farmers. Allergic rhinitis and respiratory symptoms in fruit farmers are mainly related to pollen allergy, especially gramineae pollen. They can also be related to the use of pesticides or exposure to mites .

This study examines the feasibility and acceptability of using mobile applications and biosensing (mHealth) devices in detecting vitality parameters in current smokers with and without respiratory symptoms/COPD (e.g., heart rate, blood oxygenation, steps/motion) for a future big-scale study.

INTRODUCTION Lung function assessment of preschool children is hindered by their limited co-operation in conventional tests such as peak expiratory flow (PEF) or spirometry and the methods available for younger children are, again, laborious and time consuming. However, impedance pneumography (IP) records indices of airway obstruction during normal sleep at home and has been shown accurate in wheezy preschool children (Seppä et al. J Appl Physiol 2013). AIM OF THE STUDY The general purpose of this study is to assess the clinical value of the information provided by overnight home recording of tidal breathing by means of IP technique in young children with asthmatic symptoms and inhaled corticosteroid (ICS) medication. The main hypothesis is that IP measurement can distinguish between groups whose asthmatic symptoms recur or do not recur after ending the ICS drug treatment period. METHODS The study recruits 1-5 year old children (n=75) who have presented at the emergency room due to obstructive bronchitis and for whom an ICS drug treatment period has been prescribed based on the national guidelines. The subjects will perform three overnight IP measurements at home at two weeks intervals close to and after ending of the treatment period. SIGNIFICANCE OF THE STUDY Being an affordable, simple and convenient ambulatory measurement method, IP may bring needed objectivity to asthma diagnostics and asthma drug response assessment in young children.

GER and respiratory symptoms are both common phenomenon in children. Both can coexist in the same patient by chance alone. Research reveals increased incidence for both to coexist leading to suspect a temporal association and possible causality. Therefore we conducted an observational study To determine the primary cause (RS or GER)using for the first time both PH-Impedance as measurements of GER and Wheezy monitoring (WEEM) that records simultaneously wheeze and cough noises. Both modalities will be recorded for 12-24 hours. If GER precedes cough/wheeze recordings it points to GER being the possible precipitating factor and vice versa.

Since the spread of the COVID-19 disease, several studies have reported the presence of neurological symptoms in patients infected with SARS-CoV-2 such as dysgeusia, hypo or anosmia, hypopsia, the presence of headaches or neuralgia. It has also been described an inconsistent association, in the most severe patients, neurological disorders such as labile arterial hypertension, persistent central fever, vigilance disorders as well as a poor adaptation of the cardio vascular and respiratory systems characterized by paradoxical bradycardia and the frequent absence of polypnea in response to profound hypoxemia. These different functional signs are usually described in particular in patients with impairment of the autonomic nervous system (ANS) in connection with other neuropathological processes.

the investigators hypothesis is that milk consumption, either in the acute phase and through prolonged exposure, does not cause or increase respiratory symptoms or airway inflammation. the investigators aim to objectively prove this by examining respiratory symptoms and signs and objectively measuring parameters of airway inflammation and hyper responsiveness after consumption of cow milk or soy milk substitute.

Pulmonary function tests including spirometry, lung volumes, measurements of resistance and diffusing capacity are essential in the diagnosis of several pulmonary diseases. These tests are an integral part of the diagnosis and treatment of lung diseases, but until now there is no clear evidence for the use of many of the pulmonary function tests because of a lack of adequate studies. The obscurity largely pertains to the conditions under which combinations of the various tests are indicated. Therefore the Belgian Thoracic Society, assembling all pulmonologists and the pneumology LOK/GLEM"s, will investigate this matter.

This study is an evaluation of the composition of human milk and health outcomes in children.

Asthma and chronic obstructive pulmonary disease (COPD) are chronic inflammatory conditions involving the small airways with airflow limitations resulting from genetic and environmental interactions. Currently, there are no existing subject diaries with evidence of responsiveness to measure the daily symptoms of asthma. Therefore, there is a need to either develop a new symptom diary to characterize subject burden of asthma symptoms or modify/adapt an existing tool from a related disease area for use in subjects with moderate to severe asthma. The E-RS in COPD (E-RS: COPD®) questionnaire was developed as a measure of daily respiratory symptoms associated with COPD. The fixed dose combination of fluticasone furoate/ umeclidinium/ vilanterol (FF/UMEC/VI) administered via the ELLIPTA® dry powder inhaler (DPI) has been developed for the treatment of asthma. This cross-sectional, qualitative study is designed to understand the symptoms and disease experience of subjects with moderate to severe asthma. This study will also evaluate underlying concepts that are most important to asthmatic subjects compared to symptoms and concepts included in the E-RS: COPD and two supplemental asthma items (wheeze and shortness of breath with physical activity). Approximately 32 subjects will be included in the study and interviewed via telephone. Each interview including time for consent, qualitative interview, and completion of case report forms (CRFs) is expected to last approximately 60 to 90 minutes. Subjects will be expected to complete a daily diary for the next 7 days, following the initial telephone interview.
