Active clinical trials for "Signs and Symptoms, Respiratory"

The proposed research study will be a prospective observational study designed to validate the Canadian Triage Assessment Scale (CTAS) in regard to work of breathing in patients in the emergency department. The investigators will assess inter-rater agreement between nurses & emergency physicians for assessment of work of breathing.

Pulmonary infiltrates frequently complicate the care of hematopoietic stem cell transplant (HSCT) and leukemia patients. Bronchoalveolar lavage (BAL) is frequently used to evaluate new pulmonary infiltrates in this population, however utility is limited by a historically low diagnostic yield for infection. In an effort to improve diagnostic yields, this study will complete a Fiberoptic Bronchoscopy (FOB) within 8 hours of radiographic documentation of pulmonary infiltrates, prior to initiating new antibiotic therapy. To further improve detection of microbiological pathogens, the study will utilize PCR testing with rapid turnaround time to detect atypical pneumonia (M pneumoniae, C. Pneumonia, Legionella species, and respiratory viruses) and aspergillosis.

The purpose of this study is to look at whether an investigational drug can treat the breathing symptoms of RSV bronchiolitis in children 3 to 24 months of age.

Kiryat Tivon is located close to a major industrial zone. The aim of the study is to evaluate the health status of children living in K. Tivon. The health status will be evaluated using health questionnaires and spirometry.

This is a web-based randomized survey to evaluate management of respiratory symptoms among physicians in Sweden. The aim of this study is to determine if there is a gender bias in the diagnosis of COPD and how often physicians identify that chronic refractory breathlessness requires treatment as compared to refractory pain.

Haifa bay region is located close to a major industrial zone. The aim of the study is to evaluate the health status of school children living in Haifa bay region.The health status will be evaluated using health questionnaires and spirometry.

The investigators will conduct a randomized, controlled, double-blind, crossover trial to determine whether the presence of a portable high-efficiency indoor air filter in the bedroom reduces respiratory symptoms in former smokers compared with placebo. The primary outcomes will be change in St. George's Respiratory Questionnaire - COPD (SGRQ-C) score associated with using a portable high-efficiency indoor air filter during the study period. Secondary outcomes of COPD exacerbations and hospitalizations, daily step counts, medication changes, spirometry, and cardiovascular outcomes will also be assessed.

All neonates, ages 0 to 4 months, presenting to LPCH pediatric ENT clinic for airway difficulties or stridor will be screened for inclusion. As is consistent with an acceptable standard of medical care, these children will undergo a flexible nasal endoscopic exam to make the diagnosis of laryngomalacia, as well as be weighed and a breastfeeding history taken. If laryngomalacia is present, the study staff with then administer the Infant Gastroesophageal Reflux Questionnaire (IGERQ) and an airway symptoms questionnaire (ASQ). Those babies with an IGERQ score of less than sixteen (no more than mild reflux) and an ASQ score greater than six will be eligible for randomization. The patient will then be randomly placed in the control group (placebo) or the intervention group (ranitidine 2mg/kg every 12 hours or famotidine 0.5 mg/kg daily). Patients will stay on medication for a minimum of 6 months, or until symptoms resolve. Patients will be seen in follow up at 1, 2, 3, 4, 5, 6, 8 and 10 months. At which time I-GERQ, ASQ and weights will be taken. The primary outcome measure will be the time for the ASQ score to drop to normal on ranitidine or famotidine versus placebo. A secondary outcome will be weight gain in percentile. If the patient's I-GERQ score goes above 16 at any time in the study, the patient will be crossed over to the treatment arm and started on medical treatment.

Biofeedback is a therapeutic paradigm that teaches patients how to gain awareness and control over previously unrecognized sympathetic changes such as body temperature, blood pressure, and heart rate. We propose to use a six session biofeedback protocol that includes heart-rate variability (HRV) biofeedback, respiration/relaxation training, and body temperature control to treat patients with unaddressed respiratory symptoms (e.g. shortness of breath) who are under the care of pulmonologists and have not responded to traditional biomedical approaches (e.g. inhalers, pulmonary rehab, etc.).
