Chronic obstructive pulmonary disease (COPD) is a common disease that endangers people's health, causing severe economic and treatment burdens. Sleep breathing disease, as a complication of COPD, increases the hospitalization rate and mortality of COPD. At present, community doctors have insufficient knowledge of COPD and its complications, and they also lack standardized screening and related disease management capabilities. This trail intends to use IoT medical technology to screen for COPD combined with sleep breathing diseases. It can establish a two-way referral channel between primary community hospitals and higher-level hospitals, which provides early warning services for COPD combined with sleep breathing diseases. This trial explores the impact of sleep breathing disease on COPD's acute exacerbation, which improves the understanding of COPD patients combined with sleep breathing diseases. It also improves COPD management and its complications control at the community-level and reduces COPD patients' potential risks and treatment burdens. It also explores tiered diagnosis and treatment models for COPD, promotes the construction of intelligent IoT infrastructure, and enhances standardized diagnosis and treatment of COPD at the grassroots level in China.
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most frequent complications of the COVID-19 pandemic. In these conditions, hypoxemia may result from : i) a pulmonary vascular dilatation resulting from an impaired hypoxic pulmonary vasoconstriction and leading to ventilation-perfusion mismatching within the lungs and ii) thrombosis-mediated perfusion defects. Pulmonary vascular dilation might be due to a relative failure of the physiological acute hypoxic pulmonary vasoconstriction, in the context of an over-activation of a regional vasodilatation cascade, as part of a dysfunctional inflammatory process. Perfusion abnormalities associated with pulmonary vascular dilation are suggestive of intrapulmonary shunting toward areas where gas exchange is impaired, ultimately leading to a worsening ventilation-perfusion mismatch, a regional hypoxia and a profound hypoxemia. Increased plasma levels of VEGF have been reported in moderate to severe COVID-19 pneumonia, highlighting the role of VEGF in the pathophysiology of the disease. A better prognosis has been reported in critically ill patients with lower levels of growth factors, HGF and VEGF-A at the time of ICU admission. Recent data of the study NCT 04275414 by Pang J et al have suggested that patients receiving a single-dose of bevacizumab have improved their oxygen support status in 92% of cases during a 28-day follow-up period, as compared with 62% of cases in an external cohort receiving standard care. Correcting endothelial permeability and vasodilatation with VEGF-targeted therapy could allow repair damaged vascular endothelium, have an indirect anti-inflammatory effect (limiting alveolar exudation of circulating inflammatory and procoagulant mediators) and improve oxygenation and therefore reduce the proportion of patients with severe forms requiring ICU referral and finally patient death. This clinical trial will therefore focus on the specific efficacy of bevacizumab in COVID-19 patients with severe hypoxemia.
The composition of the intestinal microbiota, the level of lipopolysaccharides, TMAO in the blood, and other parameters of patients with COPD (n=50), asthma (n=50) and the control (n=40) will be assessed as factors associated with exacerbations and respiratory symptoms in the prospective study (12 months).
AIM: To advance the development and accuracy of the Lifelight® app for the measurement of vital signs, therefore developing a non-invasive and easy-to-perform means of measuring vital signs which can be implemented across a wide range of settings, both within hospitals and out in the community. METHOD: Lifelight® is a computer program ("app") for measuring vital signs which can be used on smart devices that contain a camera. It is able to measure all of the vital signs by measuring very small changes in skin colour that occur each time the heart beats. This means that it does not need to touch the patient. The investigators believe this could be an effective way of measuring vital signs, especially during the COVID-19 pandemic when prevention of cross-contamination between patients is essential. Patients are also likely to be reassured by a contactless approach. The app uses data from looking at a person's face to calculate the vital signs. This is possible because there are tiny changes in facial skin that occur each time the heart beats. The investigators believe Lifelight® could be an effective way of measuring vital signs. The app is still under development, which means that it is still "learning" the best match between the information it collects from the face and the values of vital signs measured using the standard equipment. The app should become more accurate in calculating the vital signs as it sees more and more information from patients. So far, the app has seen data from inpatients, outpatients, patients attending GP surgeries and healthy people. This has improved its accuracy in measuring vital signs. However, the app needs to see more information so that it can be sufficiently accurate for specific clinical applications such as long-term monitoring of hypertension. To do this, it particularly needs to see information from people with abnormal blood pressures and blood oxygen levels. In order to capture the full range of observations, the app will need to be trialled with some of the most critically ill patients - some of these will not have capacity to consent to participation in the study. It also needs to see more data from people with different skin tones so the investigators can be sure it is accurate for all patients. To do this, the investigators will recruit people who are attending one of two hospitals, either as an inpatient, an outpatient, a friend/relative of a patient, or a member of hospital staff. The exact number will depend on how quickly the app "learns" and how many of the vital signs are outside of the normal range. The investigators will take the participant's vital signs using standard clinical equipment whilst recording a video of their face. The investigators will use most of these measurements and video to teach the app how to become more accurate at measuring vital signs. The investigators will keep the remaining data separate and use it to test how accurate the app is. All of the data will be kept securely. The investigators will also collect feedback from participants and healthcare staff on their experiences using the app and information that allows us to assess whether there are any savings to the healthcare economy through use of this technology.
An observational study to evaluate the accuracy of a digital cough monitoring tool to reflect the incidence of COVID-19 and other respiratory infections at the community level in the city of Pamplona, Spain.
Profile known and novel biomarkers in blood in COVID19 patients to characterize the host response to SARS-CoV-2 over time and in response to treatment. The investigators aim to: - Better understand the disease. The investigators will achieve this by characterizing the biology of COVID-19 infection and the pathophysiology of the host response using clinical data together with cellular and molecular measurements over the course of the disease. This will allow better insights for the discovery and development of novel therapeutics. - Understand why different patients have different phenotypes and disease presentations over time. The investigators will achieve this by analyzing for patient subgroups. This will allow targeted patient stratification and better matching of resources. - Understand how patients are responding to the different medications being tested in clinical trials. The investigators will achieve that by co-enrolling with therapeutic trials. This will allow an understanding of the biological effects of these interventions. Study Design: Observational adaptive study of a translational nature, combining clinical data and basic science investigations in blood samples in the same patients, longitudinally, with serial interim analyses. Primary outcomes: 90 day ICU mortality. Secondary outcomes: measures of ICU utilization and disease severity, and 90 day in-hospital mortality. The study ends after 3 months from admission to the ICU, hospital discharge or death. Location: St. Michael's Hospital (Unity Health Toronto), an academic center in downtown Toronto affiliated with the University of Toronto. The investigators will collect: A) Detailed clinical data including investigations, mechanical ventilation and cardiovascular parameters. B) Blood samples for state-of-the-art multi-omics biomarker discovery and development: cytokines, anti-COVID19 antibodies, autoimmune serology, metabolomics, transcriptomics, epigenomics, deep immune phenotyping, viral loads. For those patients who die with COVID19 The investigators will perform bedside post-mortem biopsies of lung, heart, kidney and muscle. Sampling times: From admission to the maximal severity phase through convalescence, in order to capture the evolution and dynamics of the disease and the recovery process: days 0,1, 3, 5, 7, 10, 15 and 22, and then every 2 weeks until the end of the study (3 months from admission to the ICU, hospital discharge or death).
Recently, interest in ways to monitor and care for patients remotely has significantly increased due to concerns for infection control as well as a way to increase access to regular clinic visits that may be limited for socioeconomic and geographic reasons. However, remote care can be limited by a lack of objective data to help guide clinical care. With respect to respiratory disease, caring for patients remotely may be enhanced by the ability of patients to monitor at home such things as vital signs, lung sounds, and lung function by spirometry. Enhanced methods to follow symptoms and track medication compliance may also be beneficial. These enhancements could improve care and quality of life both for persons with acute respiratory illnesses and those with chronic respiratory disease (such as asthma or COPD). The purpose of this study is to develop and study methods for patients to monitor their respiratory health at home and make that data available to medical providers to improve their care.
Drug-induced sleep endoscopy (DISE) is the most used technique for identifying the obstruction site associated with obstructive sleep apnea (OSA). This is due to the fact that it allows many patients to be examined in a daytime setting. This procedure uses sedative drugs to mimic natural sleep. However, associations with the site of upper airway (UA) collapse during natural sleep remain unclear. The aim of this explorative study is to identify UA collapse in patients with OSA using endoscopic techniques as well as flow shape characteristics and sound analyses during natural and drug-induced sleep. Furthermore, we want to optimize the measurement set-up of natural sleep endoscopy (NSE).
Chronic Respiratory Diseases (CRDs) are associated with substantial morbidity and mortality, ranking as the third leading cause of death worldwide. Pulmonary rehabilitation (PR) is a fundamental evidence-based intervention for the management of a variety of CRDs, such as Chronic Obstructive Pulmonary Disease (COPD) and Interstitial Lung Diseases (ILDs). However, the benefits of PR tend to decline over time and there is currently no strong evidence that patients translate those benefits into a more active lifestyle. There is an urgent need for evidence-based interventions to promote physical activity (PA) participation, whilst maintaining PR positive effects in the long-term. Community-based PA interventions adjusted to the local context, as well as patients' needs and preferences, might be a key strategy to meet this target. CENTR(AR) will be a sustainable response to support healthy lifestyles and enhance long-term PR benefits, by providing access to PR within Primary Healthcare Centres (PHC), followed by the inclusion in a community-based PA program, which embraces urban facilities and available resources.
