The purpose of this study is to understand why patients in the World Trade Center program have continuing breathing problems. This study will improve investigators understanding of breathing problems among individuals with World Trade Center exposure by allowing them to review and monitor medication use, lung function, and examine other conditions that can contribute to problems with breathing. The findings from the study will help investigators understand why some people have persistent lower respiratory symptoms (breathing problems) after their exposure to World Trade Center dust and fumes, and may help guide better management and treatment of these symptoms.
The objective of the study is to confirm the safety and efficacy in patients utilizing the aura6000 System for the treatment of Obstructive Sleep Apnea (OSA).

Overall Aim: To better understand the diagnostic process for prolonged respiratory events and determine the potential role of FeNO in assessing the possibility of asthma as the symptoms etiology. Study Objectives: The specific objectives of this study are to: - Determine the frequency of ICS prescription for the treatment of non-specific lower respiratory symptoms. - Determine the frequency of asthma diagnosis as an etiology for the non-specific lower respiratory symptoms. - Explore the value of FeNO in identifying asthma as the etiology of the non-specific lower respiratory symptoms. Number of Subjects: It is anticipated that up to approximately 3,000 patients will be asked to complete the brief screening questionnaire that will be used to identify up to approximately 280 eligible patients who meet the study inclusion/exclusion criteria during a (approximately) 4 to 6 week study enrollment period. Reference Product: NIOX MINO® Duration of the participants involvement in the investigation: Single Visit Performance assessments: Fractional Exhaled Nitric Oxide (FeNO) Measurements will be performed using the NIOX MINO® device according to "Instructions for NO measurements" which will be provided to each Investigative site prior to patient enrollment. Safety Assessments: The Investigator is responsible for the detection, reporting, and documentation of events meeting the definition of an Adverse Event (AE) and/or Serious Injuries as provided in this clinical investigation plan from the time of informed consent/assent and during the study period. Criteria for Evaluation: The relationship(s) between FeNO and both the diagnosis of asthma and prescription of ICS will be explored by correlation, measures of concordance and logistic modeling.
The purpose of this study is to determine whether focused sonography of the heart, lungs and deep veins can increase the number of patients with respiratory symptoms correctly diagnosed in an emergency department.
This study is an evaluation of the composition of human milk and health outcomes in children.
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.
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.
The study is designed to evaluate the efficacy of montelukast on symptom-free days in unselected group of very young children with wheeze and recurrent asthma like symptoms. The secondary aim was to evaluate the effect of montelukast on lung function, airway responsiveness, airway inflammation and use of rescue medication.
