Active clinical trials for "Respiratory Sounds"

The purpose of this study is to evaluate hair trace elements and toxic metals and plasma total antioxidant activity in children with recurrent wheezing and to evaluate whether these toxic metals and trace elements have any impact on serum cytokine levels.

This is an open-label, non-drug methodology trial in which subjects undergo a stepwise series of tests to evaluate their ability to use a mouthpiece to deliver nebulized therapy. The trial consists of a screening assessment and familiarization session, and two nebulization assessments, conducted over two site visits. The screening assessment, familiarization session and first nebulization assessment will take place at Visit 1, while the second nebulization assessment will take place at Visit 2. The total duration between Visits 1 and 2 will be 4 - 8 days. Each visit is expected to last up to 2 hours.

The present study was aimed at investigating the efficacy of nebulizing Budesonide sin comparison with intravenous Dexamethasone before extubation in prevention of post-extubation complications amongst patients admitted in intensive care unit. In this double-blind randomized clinical trial study, 90 patients (age between 18 to 65) who are intubated (at least for 48 hours) and now are ready for extubation will be enrolled in the study after obtaining a written informed consent from their parents or guardians. The investigators divide our patients randomly into two equal groups. -In the budesonide group patients underwent a therapy with nebulizing Budesonide at a dose of 1 mg diluted in 4 cc of sterile water for 20 minutes, one hour preceding extubation. After extubation patients received nebulizing budesonide via oxygen mask at the same dose every 12 hours for 48 h.i In dexamethasone group intravenous dexamethasone was administered to patient at a dose of 0.15 mg/kg before extubation. After extubation, the administration of intravenous Dexamethasone continued at the same dose every 12 h. for 48 h. Another anesthesiologist who is unaware about kind of medication, will evaluate the patients for severity of stridor. We will record the vital sings and grade of stridor every 6 hour. Respiratory rate (RR), heart rate (HR), blood pressure (BP) and oxygen saturation (SPO2) were recorded for each patient immediately before aerosol administration (time 0) and at 30 and 60 min; and 2,4,8,12,24,36 and 48 hrs. After extubation then the presence of stridor (heard with the aid of stethoscope) was recorded within 48 hr of extubation

The Polish Mother and Child Cohort is multicentre prospective study on different exposures. Prospective cohort study design enables identification of exposures that may influence pregnancy outcome and chil-dren's health, verification of such exposures by biomarker measurements and notification of any changes in exposure levels. The aim of the study is to evaluate the impact of exposure to different environmental factors during pregnancy and after birth on pregnancy outcome and children's health. Specific research hypotheses refer to the role of heavy metals, exposure to polycyclic aromatic hydrocar-bons (PAHs) and environmental tobacco smoke (ETS) in the aetiology of intrauterine growth retardation (IUGR), preterm delivery (PD) and the risk of respiratory diseases, allergy and poor mental and physical development. It is also intended to explain the role of oxidative stress and nutritional status of the pregnant women. The impact of occupational exposures and stressful situations on pregnancy outcome will be evaluated from question-naire data. The results of the study will help to determine levels of child prenatal and postnatal exposure in several areas of Poland and their im-pact on course and outcome of pregnancy and children's health. This protocol concerns the children that are followed-up from birth to the age of 2 years to determine long term effects of pre- and postnatal environmental exposures.

Infants will be enrolled into this study in one of three groups. First, there will be a group of full term infants with no history of wheezing. Second, there will be a group of infants receiving a ct scan that is non-respiratory related. Third, there will be a group of infants that are born full term but have a history of wheezing of at least 3 episodes. The three groups will be compared to see if there is a difference in lung function, lung structure and lung size. Besides comparing the testing results we will be evaluating environmental and inherited characteristics. There are 2 purposes of this study. The first purpose is: To determine whether asymptomatic groups of infants at high risk for wheezing (Environmental tobacco smoke (ETS) exposure, Fm Asthma, male Gender) have fixed or reversible airway narrowing. The second purpose of this study is: To determine the relative contributions of fixed and reversible airway narrowing in infants with recurrent symptomatic wheezing, and to determine whether fixed and reversible airway narrowing is related to ETS exposure, Fm Asthma, and male Gender.

As most of the upper airways infections (UAI) leading to wheezing are secondary to viral triggers, the possible antinflammatory and antiviral role of resveratrol has been suggested in several studies, both in vitro and in vivo. However, its efficacy has been studied only when evaluating upper respiratory symptoms. With the aim to define new approaches in patients with recurrent wheezing triggered by UAI we have performed a prospective observational study to evaluate the efficacy of a short-course of intranasal resveratrol, administered for 7 days at the beginning of UAI, when compared to standard nasal lavage with 0.9% saline solution, in terms of reduction in wheezing episodes.

Children 2-11 years of age who are given the influenza vaccine (inactivated influenza (IIV) or live attenuated influenza vaccine (LAIV)) as part of their routine care can enroll in this study if their parent has the ability to receive and send text messages. Children enrolled in this study will be observed daily for an eight-day period starting on the day of vaccine administration, and then continuing over the next 7 days, and then weekly for 42 days. On the day of enrollment and nightly for the next seven days, the parent will report via text message what their child's highest temperature is. If fever is present, they will then be prompted for additional information including other symptoms, antipyretic use and medical care sought. On day 3 as well as weekly from day 7 through day 42 post-vaccination, parents will be asked via text message about breathing problems, specifically cough, wheezing and chest tightness. They will also be asked about medications taken and care sought. The purpose of this study is to assess the feasibility of collecting this data.

The aim of this study is evaluation of the effect of administration nebulized budesonide after extubation. The specific objectives of our study are to determine whether multiple doses of nebulized budesonide are effective to reduce or prevent postextubation edema. In this double-blind randomized clinical trial study, 70 patients (age between 18 to 65) who are intubated (at least for 48 hours) and now are ready for extubation will be enrolled in the study after obtaining a written informed consent from their parents or guardians. The investigators divide our patients randomly into two equal groups. -Patients who are in budesonide group will receive nebulized budesonide (1 mg-every 12 hours; n=35) and patients in placebo group receive placebo (normal saline; n=35) until 48 hours after extubation. If patient have extubation criteria the investigators will extubate him and for 24 hours after, another anesthesiologist who is unaware about kind of medication, will evaluate the patients for severity of stridor. We will record the vital sings and grade of stridor every 6 hour. Respiratory rate (RR), heart rate (HR), blood pressure (BP) and oxygen saturation (SPO2) were recorded for each patient immediately before aerosol administration (time 0) and at 30 and 60 min; and 2,4,8,12,24,36 and 48 hrs. After extubation then the presence of stridor (heard with the aid of stethoscope) was recorded within 48 hr of extubation.

This clinical trial is conducted within the research project 'Computerized Lung Sound Analysis'. The research goal is the development of a system enabling the automatic classification of lung sounds, which will result in a decision support system for physicians. The objective of this trial is to create a small lung sound corpus, enabling the development of a prototype of the described system. Therefore, investigators record lung sounds with several lung sound transducers distributed on the posterior chest of human test subjects.

The study goal is to create a database of respiratory sounds recordings, to evaluate and validate the WIM technology and to evaluate the efficacy of a specific treatment by comparing the severity of the respiratory symptoms before and after the administration of the treatment.
