This study assessed the respiratory health of schoolchildren from the canton of Zurich by combining self-reported information on respiratory symptoms with lung function test results and air pollution measurements. Luftibus in the school (LUIS) is a population-based study conducted in the canton of Zurich, Switzerland. Between the years 2013 and 2016 a bus with equipment for lung function testing and air pollution measurement visited numerous schools across the canton Zurich. The parents of the schoolchildren filled in a questionnaire with validated questions on upper and lower respiratory symptoms, trigger factors, diagnosis, treatment of respiratory symptoms, health behavior and environmental factors. The children were interviewed using a shorter questionnaire. Fieldworkers measured lung function (spirometry and double tracer gas single-breath washout) and an airway inflammation test (fractional exhaled nitric oxide) in the bus. The recruited population included 3500 schoolchildren aged 6 to 16 years from the canton of Zurich. Respiratory symptoms and their influence on physical activity and sleep have a strong impact on children's quality of life and school performance. The results of this study will provide new insights on schoolchildren's respiratory health that may help to establish new recommendations and influence policy makers' decisions.
The aim of this study is to assess the effectiveness of a home-based exercise training program in COPD patients who did not participate in an inpatient or outpatient rehabilitation program within the last 2 years.
Extubation stay at high risk of reintubation even scheduled and in the best condition of hematosis. Re-intubation's rate in main studies in chronic obstructive diseases reach to 20% and it is associated to a higher mortality, higher pneumonia under mechanic ventilation, and higher duration of hospitalization especially in intensive care units. Place of NIV in this situation is still on evaluation. A recent meta-analysis demonstrates that use of NIV in post-extubation in COPD seems to decrease re-intubation rate. HFO, thanks to its properties (oxygen, humidification and heat with high flow) could be useful in this population in ventilatory weaning. Compared to oxygen conventional therapy with high-concentration mask, HFO seems to be as efficient and better tolerated. A recent study shows that HFO is non-inferior to NVI in post-extubation in patient with high risk of re-intubation. Furthermore, oxygenation in post-extubation should be optimized to avoid hypoxemia and hypercapnia in this patient at risk of hypoventilation. Place of AFOT could improve hematosis by providing adapted flow of oxygen to each patient. The investigator choose the hypothesis for this study that HFO is as effective and tolerated in post-extubation than NIV with AFOT.
--> This is a substudy of the main ESTxENDS trial (NCT03589989). Respiratory symptoms outcomes should be considered secondary outcomes of the main smoking cessation outcome formulated in NCT03589989. Cigarette smoking is the leading cause of preventable death in Switzerland. Cigarette smoking eventually kills one in two smokers, mostly through cancer, heart disease and respiratory failure. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. Studies suggest that ENDS use improves health outcomes, such as reducing respiratory symptoms, and presents only minimal respiratory risks, such as mild throat irritation and dry cough. In a prospective 6-month randomized, controlled trial evaluating smoking reduction/abstinence in 300 smokers not intending to quit experimenting two different nicotine strengths of a e-cigarette model compared to its non-nicotine choice, respiratory symptoms similarly improved in all three study groups. One study compared the short-term effects of cigarette smoking to ENDS use and found that cigarette smoking led to an acute reduction in lung function, which was not observed with ENDS. Findings on short-term airway resistance is conflicting. Short term increase in resistance in ENDS users might be caused by aerosolizing the liquid, and not by the same substances that harm lung function in cigarette smokers. Smokers who shifted from tobacco cigarettes to ENDS have offered anecdotes of dramatically improved lung function, but animal models suggest that ENDS liquids can increase markers of asthma. No large randomized trials have tested the effect of ENDS on respiratory symptoms. For the main ESTxENDS trial (NCT03589989), cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-months period. Respiratory symptoms such as chronic obstructive pulmonary disease (COPD), asthma and dyspnea will be assessed by means of questionnaires at baseline and at 6-, 12- and 24-months follow up. This trial will provide useful data on changes in respiratory symptoms in a large sample of participants.
This study will be used to evaluate and observe the overall performance and controls of the Helix ventilator. Pressure and flow data between participants' current devices and the Helix ventilator will be assessed in either invasive or non-invasive ventilation. To evaluate ventilator performance, pressure and waveform data will be assessed as well. Also, patient and caregiver feedback will be captured. The target population is infants to adults weighing more than 5kg. Participants will be recruited by Boston Children's Health Physician's Group. Up to thirty participants will be enrolled in the study.
This study is a prospective observational study which aim to evaluate the feasibility of a total and systematic home respiratory rehabilitation training program in patients who will undergo thoracic surgery, and otherwise tend to define failure reasons.
The aim of this study is to assess the effectiveness of a home-based exercise training program in COPD patients who have completed a pulmonary rehabilitation.
This trial is multicenter prospective study to evaluate clinical efficacy of respiratory rehabilitation personalized mobile services for respiratory disease.
This study evaluates frequency of exacerbations, respiratory symptoms, physical exercise intolerance and abnormal lung functions among participants who use IQOS with heatsticks compared to smokers of conventional cigarettes
