Filter by:xrAI (pronounced "X-ray") serves as a clinical assistance tool for trained clinical professionals who are interpreting chest radiographs. The tool is designed as a quality control and adjunct, limited, clinical decision support tool, and does not replace the role of clinical professionals. It highlights areas on chest radiographs for review by an interpreting clinician. The objective of this study is to utilize machine learning and artificial intelligence algorithms (xrAI) to improve the quality and efficiency in the interpretation of chest radiographs by family doctors, nurse practitioners, emergency medicine physicians, internists, pulmonologists, and radiologists. The hypothesis is that the addition of xrAI's analysis will reduce inter-observer variability in the interpretation of chest radiographs and increase participants' sensitivity, recall, and accuracy in pulmonary abnormality screening.
The purpose of the study is to explores various psycho-social, physiological, cognitive, behavioral, and environmental factors that may affect the association between pulmonary status and Susceptibility to Electronic Cigarette Use
Secondary data analysis will be performed as our approach to complete the study. A nationally representative dataset (BRFSS, 2017) will be used to answer the above hypotheses.
Inhalation burn injury and lung complications caused by large surface burns occurring during a fire remains a serious problem. Pulmonary rehabilitation has been used successfully to improve pulmonary function(PF) in patients with chronic obstructive pulmonary disease. But there were no studies that pulmonary rehabilitation induce improvements in PF in patient with large surface burn and inhalation injury. The investigators will performe pulmonary function and respiratory muscles strength evaluation in 40 patients with thermal injury in order to evaluate the effects of pulmonary rehabilitation in patients with thermally injury.
Purpose: To determine unmet functional needs in patients referred to the Palliative Care Unit at Rigshospitalet, Copenhagen University Hospital will be asked to fill out self reported questionnaires regarding problem intensity, problem burden and felt needs, physical functioning, emotional functioning, fatigue, sleep, distress. Furthermore patients physical function will be evaluated.
Postoperative pulmonary complications (PPCs) are the most common complication following thoracic surgery. PPCs are associated with prolonged hospital stay, increased morbidity, mortality, ICU admission, and healthcare costs (Azhar, 2015). Current preoperative optimization in this patient group includes smoking cessation and management of Chronic Obstructive Pulmonary Disease with inhaled bronchodilators and inhaled steroids as indicated. There have been studies using preoperative incentive spirometry in patients undergoing laparotomy with conflicting results, but scant data on its use in patients undergoing one-lung ventilation (Tyson, et al., 2015; Cattano, et al., 2010). A study from 2013 investigated the effectiveness of incentive spirometry in patients following thoracotomy and found conflicting results, without significant improvement in lung function or reduction in PPCs, but a larger difference in frequency of PPC was noted, indicating possible benefit to intervention and a need for further study (Agostini, et al., 2013). Volume-based incentive spirometry pre- and postoperatively has also been found to improve pulmonary function and diaphragm excursion in patients undergoing laparoscopic surgery (Alaparthi, et al., 2016). Patients customarily receive an incentive spirometer for use postoperatively in the PACU. There is scant data in the thoracic surgery population concerning prehabilitation by dispensing the incentive spirometer at the PACT evaluation.
The objective is to verify that there is a decrease in the pulsed oxygen saturation with the digital sensor. That is, the drop in oxygen saturation in COPD patients during inhalation is real and not due to an artifact of the measuring tool, because oximeters need a quality pulsatile signal to properly measure oxygen saturation
--> This is a substudy of the main ESTxENDS trial (NCT03589989). Pulmonary function 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 and still more than a quarter of the Swiss population smokes cigarettes. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer, e-cigarette 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. The inhaled ENDS aerosol appears safe in laboratory conditions, its long-term effects on pulmonary function remains unknown. This study will therefore investigate the impact of ENDS on lung function in smokers, who attempt to quit using ENDS compared with smokers, receiving only smoking cessation counseling with nicotine replacement therapy (NRT). Multiple breath washout (MBW) is an established technique for assessment of peripheral airway function in pediatrics and its use is emerging in adult medicine, as it offers a better sensitivity to assess small airway disease before large airway involvement can be detected using conventional pulmonary function tests (PFT - spirometry, body plethysmography and diffusing capacity test). Preliminary evidence from limited studies suggest MBW parameters (LCI, Scond, Sacin) can be impaired in smokers with normal lung function and improve after smoking abstinence. Primary objective of this substudy is to assess changes in LCI from baseline to 6 months post target quit date (TQD) in cigarette smokers randomized to the intervention group compared to the control group. 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 standard of care, i.e. smoking cessation counseling and encouragement to use NRT. Smoking cessation counseling will be provided in person at the first clinical visit and then over the phone at the target quit date and again at week 1, 2, 4 and 8 after the target quit date. Participants in the control group will receive only standard of care. All participants will be followed over a 6-month period. After 6 months, participants will be asked to come to a final clinical visit.
The aim of this study is to investigate the use heated humidified high-flow nasal cannula (HHHFNC) in pulmonary rehabilitation and analysis of cardiopulmonary parameters in adult patients.
This study is designed to enhance the understanding of the possible health effects of e-cigarette use by relating the acute and long-term use of e-cigarettes and conventional cigarettes ("products") to well-validated cardiovascular and pulmonary disease biomarkers. Participants will be enrolled in 3 groups: exclusive e-cigarette users, exclusive cigarette smokers, and a control group of never-users. Participants can expect up to 4 weeks of study participation.
