Active clinical trials for "Lung Diseases"

ScreenFlow is a chronic obstructive pulmonary disease (COPD) screening tool currently being studied and iteratively developed that incorporates a questionnaire administered on a tablet and data from a digital peak flow meter to calculate a risk score to identify the risk of developing moderate-to-severe COPD for the participant. The purpose of this study is to assess the usability of ScreenFlow deployed as a free-standing kiosk and observe where users encounter trouble navigating the system. The kiosk will be situated in a public area of a hospital where passersby can approach and fill out a ScreenFlow survey if they meet the eligibility criteria. A subset of participants will be asked to participate in a follow-up questionnaire about their experience using the system and about any follow-up action they may have taken caused by their results from the ScreenFlow screening.

The purpose of this study is to monitor adherence to a clothing-attached breathing monitor, respiratory patterns, and activity levels in COPD patients, and correlate those respiratory patterns and activity levels with patient-reported symptoms and events. To achieve this purpose, Spire will collect data from a wearable monitor that participants attach to the participant's clothing, an associated smartphone application, and completion of weekly questions. The wearable monitor and the consumer smartphone application to be used are consumer products and currently available in the market. This study does not include clinical intervention and no doctors will be involved in this study. No clinical tests or office visits are included in this study. All data will be collected through an online survey tool and remotely through the wearable sensors.

A cross sectional observation study of body composition in COPD patients consecutively hospitalized with acute exacerbation.

This two-year pilot study will test whether a one-page "Jumpstart Form" will affect goals-of-care discussions in the hospital. This form will be provided to clinicians and will include patient-specific information about preferences for goals-of-care communication and for care, as well as tips to improve this communication. Jumpstart forms will also be provided to patients or, if they are unable to communicate, their surrogates/family members. The information on the form will be obtained from questionnaires. The form is tailored to help patients and surrogates talk with clinicians about goals of care. This study is based on a successful application of Jumpstart Form in the outpatient clinic setting.

The purpose of this research study is to develop CT scanning and image analysis techniques to help define and measure several key properties of the pulmonary system that cannot be obtained by other tests or exams.

Chronic Lung Disease (CLD) of Prematurity is a common yet challenging co-morbidity affecting extremely premature newborns. Multifactorial influences leading to this co-morbidity is known and targeted in various research studies. Gastroesophageal reflux (GER) is common among the same cohort of patients. The investigators hypothesize that recurrent milk reflux into the airways of the premature babies worsen the inflammation of premature lungs and is a major contributor of CLD. The investigators hypothesize that Continuous feeding (CF) minimises GER and micro-aspiration, thereby reducing the incidence and severity of CLD in high-risk infants. Our aim is to compare the effect of intermittent bolus versus continuous intra-gastric feeding on the incidence and severity of CLD in very low birth weight infants ≤ 1250 grams.

Peripheral muscle oxidative function is altered in COPD(chronic obstrutive pulmonary disease) patients. Multiple factors could contribute to this dysfunction including chronic hypoxia and deconditioning (sedentarity). The evaluation of mitochondrial function is based on invasive method (muscle biopsy and in vitro respirometry) or magnetic resonance spectroscopy limited to small muscle groups. Recently, a non invasive method has been described using Near InfraRed Spectroscopy (NIRS). During arterial occlusion, muscle deoxygenation is only dependent of local oxygen consumption. The time constant recovery (k) of the deoxygenation during repeated ischemia periods has been shown to be correlated to measurements of maximal mitochondrial capacity. k is lower in COPD patients compared to smokers without bronchial obstruction. However, the influence of arterial hypoxia has never been studied precisely, no more than the confounding effect of deconditioning on k. So , the aim is to compare k in COPD patients with chronic hypoxemia (treated with long term oxygenotherapy, LTOT+ group) and patients without hypoxia, matched for their physical activity (LTOT- group). The hypothe is that k will be lower in LTOT+ group compared to LTOT- group and that short term O2 supplementation will improve it, which would suggest a muscle hypoxia. By contrast, O2 should not influence k in LOT- group, in whom it is mainly determined by muscle conditioning.

To compariing the uniportal and tubeless video assisted thoracic surgery and trnsbronchial lung cryobiopsy within the multidisciplinary discussion context in the diagnosis of interstitial lung disease，and assess the safety and cost-effectiveness. This is a prospective control trial.

As in-clinic pulmonary function testing is greatly restricted due to Coronavirus Disease 2019 (COVID19), alternative approaches to monitoring patients with long-term respiratory conditions need to be developed and assessed. This project will evaluate the feasibility of a remote monitoring programme designed for interstitial lung disease (ILD) [including idiopathic pulmonary fibrosis (IPF)] patients which includes patient-reported spirometry & pulse oximetry (to estimate lung airflow and oxygen levels in the blood). Patients with a confirmed diagnosis of ILD will be asked to measure spirometry & pulse oximetry once/day for approximately three months. Each patient will be supplied with a spirometer & pulse oximeter for home use. There will be no other changes to patients' care. The clinical teams responsible for care of the patients will be able to view all patient-recorded data immediately after data are recorded by the patient. Feasibility of remote monitoring will be assessed by determining the proportion of patients who provide measurements at least 3 times/week and on at least 70% of days in the observation period. Patient engagement (Patient Activation Measure), changes in spirometry measurements over time and healthcare resource utilisation (e.g. number of in-clinic visits) will also be assessed. Other outcomes assessed will include estimation of the proportion of patients with significant decreases in lung function, number of occasions where critical alert values of physiological parameters are reported and number of interventions by healthcare professionals in response to observations or alerts from remote monitoring. Feedback from patients and healthcare providers on user experience will also be sought. Learnings from this project will be used to assess the wider application of delivery of digitally-based remote monitoring in management of long-term respiratory conditions.

Studies have documented impaired cognitive function in patients with COPD. The possible reasons for this and correlation to the severity of the disease are not well described. This explorative study examines the cognitive skills of COPD patients, quantified by their ability to drive a vehicle and other cognitive test. Furthermore, we want to study the cognitive skills in COPD patients before and after they are diagnosed with and treated for obstructive sleep apnoea (OSA). The overall hypothesis is that chronic lung patients´ cognitive skills correlate with the severity of their disease. We expect that their ability to drive a vehicle drops in relation to the severity of the disease and to comorbidities.
