Active clinical trials for "Respiratory Sounds"

The effect of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD) has been based on systemic outcome measures, however, little is known about the effectiveness of this intervention on patients' lung function. The forced expiratory volume in one second (FEV1), despite of being the gold standard for assessing lung function in COPD, is poorly responsive to pulmonary rehabilitation. Thus, an objective and responsive outcome measure to assess the effect of pulmonary rehabilitation on lung function is needed. Computerized respiratory sounds have been found to be a more sensitive indicator, detecting and characterizing the severity of respiratory diseases before any other measure, however its potential to detect changes after pulmonary rehabilitation has never been explored. Therefore, this study aims to assess the effects of pulmonary rehabilitation on the characteristics of computerized respiratory sounds in patients with COPD. A randomized controlled study with one group undergoing pulmonary rehabilitation (n=25) and other group receiving standard care (n=25) will be conducted. The pulmonary rehabilitation program will included exercise training (3*week) and psychoeducation (1*week). Computerized respiratory sounds, lung function, exercise capacity, quadriceps muscle strength, health-related quality of life and health services use will be assessed in both groups, at baseline, immediately post-intervention and at follow-ups (3 and 6 months after PR). Descriptive and inferential statistics will be used. It is expected that significant changes occur on the characteristics of computerized respiratory sounds in patients enrolled in the pulmonary rehabilitation group, in comparison with patients receiving standard care. Thus, computerized respiratory sounds could provide a simple, objective and non-invasive measure to assess lung function changes after pulmonary rehabilitation.

The purpose of this long-term follow-up (LTFU) study is to evaluate the incidence of the clinical diagnosis of asthma and the frequency of wheezing in infants and children with respiratory syncytial virus (RSV) infection who were treated with (lumicitabine or placebo) and have completed their last planned study-related visit in a feeding Phase 2 study (64041575RSV2004).

The study aims to analyze and compare the clinical effects of using inhaled budesonide or intravenous dexamethasone in the treatment of postextubation stridor on children admitted to the pediatric intensive care units at Hospital Municipal do M´Boi Mirim and Hospital Albert Einstein.

The incidence of physician confirmed asthma is approximately 4-7% in children. An additional 5% of children suffer from infection-related bronchiolitis and obstructive bronchitis. Of all patient visits at pediatric emergency rooms, 1 out of 10 is due to breathing difficulties with a great proportion leading to hospitalization. Salbutamol is the most commonly used drug in the treatment in acute bronchial obstruction. A vast majority of children require a spacer device (valved holding chamber, VHC) for the delivery of the drug aerosol. There are several different types of VHC on the market, but no recommendations on the device selection have been published. Both in in vivo and in vitro studies significant differences between different spacer devices have been reported. The study compares two different VHCs in the treatment of acute breathing difficulties in children. The end-points in this randomized physician-blinded study are symptom relief, rate of hospitalization, symptom recurrence, treatment compliance, and adverse events. The study will be conducted in pediatric emergency rooms (ER) in three university hospitals in Finland and one private clinic that routinely treat this type of patients. The treatment is given according to national treatment guidelines and no blood samples are drawn for study purposes. Both of the VHCs used in this study have been approved for use in clinical practice.

We can not predict which wheezing child younger than 3 years of age benefits from systemic glucocorticoid and which one does not. It is not known whether the differences in the efficacy are related to the differences in viral etiology, atopy, immunogical maturity or age of the patient. The study aims to answer the following questions: 1. What is the viral etiology of acute childhood expiratory wheezing? 2. What is the efficacy of prednisolone in relation to age, atopy and viral etiology in acute childhood wheezing? 3. Does prednisolone treatment increase risk for secundary bacterial infection in acute childhood expiratory wheezing? 4. What is the significance of inflammatory markers in predicting the efficacy of systemic steroid or patient outcome in acute childhood expiratory wheezing? Study will follow randomized, double blind, placebo-controlled parallel design. Study will start in Septemper 2000 and will be performed at the Department of Pediatrics, Turku University Hospital, Turku Finland. The study population will be 300 hospitalized wheezing children aged 3 months - 15 years. Investigational drug will be prednisolone, first dose 2 mg/kg, then 2 mg/kg/d/3 (max. 60 mg/vrk) p.o. for 3 d and comparative drug will be placebo tablet similar to investigational drug with the equal dosage. The primary outcome will be the time until ready for discharge. The study will provide new and important information for the diagnostics, treatment, disease outcome and prevention of acute childhood expiratory wheezing.

Assessing the feasibility and testing the accuracy of the developed artificial intelligence algorithms for detection of wheezes and crackles in patients with lung pathologies in clinical settings on unseen local patient data acquired through three digital stethoscopes.

The study will be conducted in two hospitals of the same geographic area. It will be included children <3-years-old with recurrent wheezing attacks, confirmed by the review of the medical records, in the previous 12 months or a shorter time for those younger than one year.

In this study children with recurrent wheezing (>/= 2 episodes in the last 6 months)and aged less than 2 years will be enrolled as outpatients. They will undergo lung function evaluation by Rint and by assessment of the flow curves at baseline and after 4 weeks of treatment with Montelukast 4 mg/day. Symptom dairies will be filled by parents during the study period.

This observational study evaluates whether lung sound analysis with LungPass device can be used to differentiate upper and lower respiratory tract infections (URTI and LRTI)

Almost 50% of all children have at least 1 episode of noisy breathing before the age of 2 years and almost 25% of these children have more episodes of noisy breathing. The lack of an objective technique for diagnosing noisy breathing children often leads to overrated diagnosis of "wheezing", whereas there may be other noisy breathing phenotypes, like "rattling", that don't favor from the same therapeutic treatment. Presumably, different underlying pathophysiological mechanisms are involved with different biomarker profiles characteristic for different phenotypes. The goal of this study is to optimize the diagnosis of noisy breathing infants and toddlers. Children will be followed for a treatment period of 6 weeks and will visit the paediatrician 3 times (week 0, 3 and 6). During the consultations breath sound analysis will be performed and a breath sample and a nasal mucus will be collected to analyse biomarker profiles. Both methods for diagnosing noisy breathing infants are non-invasive and will be compared to the standard procedure of the paediatrician which consists of auscultation and palpation of the chest. An objective and non-invasive method for diagnosing noisy breathing infants and toddler will pave the way for more cost-effective and personalized prescription of therapies which will increase the quality of life of children with noisy breathing.
