Machine Learning-based Models in Prediction of DVT and PTE in AECOPD Patients
Machine LearningChronic Obstructive Pulmonary Disease4 moreChronic Obstructive Pulmonary Disease (COPD) is a common respiratory system disease characterized by persistent respiratory symptoms and irreversible airflow restriction, which seriously endangers people's health. Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) refers to individuals who experience continuous deterioration beyond their daily condition and need to change their routine medication. AECOPD is usually caused by viruses and bacteria, and patients require hospitalization, which brings a huge economic burden to society. AECOPD patients often have limited activities. Because long-term chronic hypoxia causes venous blood stasis, siltation causes secondary red blood cell increase, and blood hypercoagulability, AECOPD patients have a high risk of pulmonary embolism (PE). Pulmonary Thrombo Embolism (PTE) refers to a disease caused by blockage of the pulmonary artery or its branches caused by a thrombus from the venous system or right heart. AECOPD patients experience elevated hemoglobin levels and increased blood viscosity due to long-term hypoxia. At the same time, such patients have decreased activity, venous congestion, and are prone to thrombosis. After the thrombus falls off, it can travel up the vein, causing PTE to occur in the right heart PTE is often secondary to low deep vein thrombosis (DVT). About 70% of patients were diagnosed as deep vein thrombosis in lower limb color ultrasound examination. SteinPD conducted a survey on COPD patients and general patients from multiple hospitals. The results showed that by comparing adult COPD patients with non COPD patients, the relative risk of DVT was 1.30, providing evidence for AECOPD being more likely to combine with PTE AECOPD patients with PTE have similarities in their clinical manifestations. It is difficult to distinguish between the two based solely on symptoms, such as cough, increased sputum production, increased shortness of breath, and difficulty breathing. They lack specificity and are difficult to distinguish between the two based solely on symptoms, which can easily lead to missed diagnosis. CT pulmonary angiography (CTPA) is the gold standard for the diagnosis of PTE, but due to the high cost of testing and high equipment prices, its popularity in grassroots hospitals is not high. Therefore, analyzing the risk factors of AECOPD patients complicated with PTE is of great significance for early identification of PTE. At present, although there are reports on the risk factors for concurrent PTE in AECOPD patients, there is no specific predictive model for predicting PTE in AECOPD patients. In clinical practice, risk assessment tools such as the Caprini risk assessment model and the modified Geneva scale are commonly used for VTE, while the Wells score is the PTE diagnostic likelihood score. The evaluation indicators of these tools are mostly clinical symptoms, and laboratory indicators are less involved, It is difficult to comprehensively reflect the patient's condition, so the specificity of AECOPD patients with PTE is not strong. The column chart model established in this study presents a visual prediction model, which is convenient for clinical use and has positive help for the early detection of AECOPD patients with PTE. In addition, medical staff can present the calculation results of the column chart model to patients, making it easier for patients to understand. It helps improve the early identification and treatment of AECOPD combined with PTE patients, thereby improving prognosis.

Mixed Anxiety DepressionDiabetes Mellitus4 moreThe health care is faced by a growing challenge in the years to come: increasing age and chronic morbidity raising the costs, combined with decreased work participation. Among the conditions on the rise, we find anxiety/depression, musculoskeletal conditions, type 2 diabetes and chronic obstructive pulmonary disease. Recently, the rise of the Corona pandemic has yielded another group of (primarily young) patients with decreased work capacity, the post-Covid syndrome sufferers. The aim of the present study is to establish, describe and summarize the experiences with a novel approach to rehabilitation for five of the most costly conditions; 1) low back pain, 2) chronic obstructive pulmonary disease, 3) type 2 diabetes mellitus, 4) mixed anxiety/depression and 5) post-Covid fatigue. The concentrated interdisciplinary rehabilitation is characterised by three phases; Pre-intervention preparation (1-2 months): with the aim to mobilize the patients' resources for change Concentrated group intervention (2-5 days): interdisciplinary team - individually tailored training (further described below) Post-intervention follow-up (1 year): digital follow-up with the aim of integrate the changes into everyday living The concentrated intervention: The core intervention is based on trans-diagnostic features of the highly successful 4-day intervention for Obsessive Compulsive Disorder, namely: Initiate treatment when the patient is ready for change Focus on the behavioral patterns which maintain the disorder and help the patient to identify situations where they can choose to break the pattern ("micro-choices"). Assist the patient when they practice breaking the patterns. This may pertain to how they do physical training or to the way they walk, sit, eat, talk, take their medication and sleep, or to how they engage in social activities or take care of others. Use long sessions to ensure that they face a broad range of potential micro-choices Work side-by side with others going through an analogous pattern of change Prepare them for taking responsibility for integrating the change into every-day living Main outcomes will be Completion rates Patient satisfaction Changes to perception of illness Patient activation Secondary outcomes will be Level of functioning Qualitative description of participants' experiences

COPD (Chronic Obstructive Pulmonary Disease)The purpose of this study is to demonstrate that the lung function effect from orally inhaled BGF delivered via HFO propellant is equivalent to the lung function effect from orally inhaled BGF delivered via HFA propellant in participants with COPD. The study duration for each participant will be approximately 15 to 16 weeks and consist of: A screening and placebo run-in period of approximately 2 weeks prior to first dosing Three treatment periods of approximately 4 weeks each (one period for each of 3 study interventions) A final safety follow-up visit via telephone contact approximately 1 to 2 weeks after the final dose administration Participants will be provided with rescue SABA (albuterol or salbutamol) to be used as needed throughout the study. Participants will attend in-clinic study visits approximately weekly during the screening/run-in period (Visits 1, 2, and 3), then every 4 weeks (Visits 4, 5, and 6) to receive take-home study treatment, measure their lung function, and assess their health and safety
Dream Analysis in COPD Patients
Chronic Obstructive Pulmonary DiseaseSleep is a fundamental period in life. In a previous work, the investigators have shown that COPD patients presented on the EEG figures found in patients with chronic pain: Alpha-Delta. The link between dyspnea and pain is very strong and this Alpha-Delta could, in these COPD patients, be the witness of nocturnal dyspnea. Although it is not possible in a non-awake patient to evaluate reliably the dyspnea, sleep offers us a window on the emotions and the feeling of the patient: Dreams. A few studies have shown the link between breathing and dreaming, but none of them has focused on nocturnal dyspnea. Our working hypothesis is that respiratory abnormalities in COPD patients are responsible for nocturnal dyspnea, which is reflected in the content of these patients' dreams.
Markers of COPD Exacerbations
COPDCOPD ExacerbationAcute exacerbations of COPD (AECOPD) are episodes of acute worsening of respiratory symptoms that require additional therapy. Exacerbations play a pivotal role in the burden and progressive course of COPD (1). Each event contributes to a progressive decline in lung function (2), reduced health status, low physical activity level (3) and increased health care costs (4). As such, disease management is predominantly based on the prevention of these episodes (1). Yet, in the Netherlands, 30.000 people are admitted to the hospital for an AECOPD every year (5). Although most AECOPD have an infectious origin (6), the underlying mechanisms are heterogeneous and predicting their occurrence in individual patients currently remains unsuccessful (7-9). Furthermore, there is a lack of our understanding in the longitudinal alterations in microbial composition and host-microbiome interactions in the stable state, at AECOPD and during recovery in patients with COPD. This knowledge is essential to improve the early and accurate diagnosis of (the different types of) AECOPD, and for the development of novel antimicrobial and other therapeutic targets and subsequent personalized treatment. These challenges need to be addressed in order to reduce the future impact of these events, avoid unnecessary treatments of individual patients, reduce healthcare utilization and improve overall care for patients with COPD. The current 'Early diagnostic BioMARKers in Exacerbations of COPD' (MARKED) study was designed to investigate several of these gaps in the management of COPD exacerbations. It is anticipated that complex biomarker panels, rather than a single biomarker, will be identified. Since AECOPD are heterogeneous events in terms of origin, trigger, severity, duration, need for treatment and overall clinical presentation (1, 6, 10-15), we expect to identify different biomarker panels for different subtypes of AECOPD. Furthermore, AECOPD diagnosis relies heavily on the exclusion of differential diagnoses (1), which further rules out the potential of a single predictive AECOPD biomarker.
Swiss Chronic Obstructive Pulmonary Disease (COPD) Management Cohort
Chronic Obstructive Pulmonary DiseaseCOPD ExacerbationBackground Chronic Obstructive Pulmonary Disease (COPD) is an inflammatory disease of the lungs, which is most commonly caused by smoking. It is characterized as not fully reversible airflow limitation, chronic cough and dyspnoea. Being the fourth leading cause of death worldwide, COPD is an important public health challenge and can be prevented and treated. It is estimated that at least 400,000 individuals in Switzerland are affected by COPD. This number may increase in the coming years due to increasing nicotine consumption. In response to the rising trend, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) has established new guidelines on the global strategy for diagnosis, management and prevention of COPD. Systematic diagnosis and stratification are crucial for effective treatment measures. As COPD is an irreversible and progressive disease, its treatment aims an early detection and better management, which leads preventing progression. Disease management programs have shown that only patients who understand their exacerbation symptoms can benefit. Moreover, it is a major goal to improve health-related quality of life by reducing symptoms and decelerating disease progression. Spirometry is the golden standard for the diagnosis of COPD, to assess the severity of the obstruction, and as a guide for optimal therapeutic measures. Aim of the study The objective of this project is to establish a COPD cohort database to allow high quality research on diagnosis, treatment, complication and progression of COPD on long-term course. Spirometry should be used consistently for the diagnosis and the monitoring of the development of the disease. Using collected information such as spirometric data, disease progression's data and therapeutic measures should help improve the management and self-management of the patients. Methods 3.1 Study design We are conducting a prospective cohort study, based on COPD patients from northern and western Switzerland, who are managed under primary care setting. Patients with mild to very severe COPD (GLOD stages I-IV) are enrolled in the study. Currently, 67 General practitioners (GPs) are participating in our Study. Each GP recruits 1-20 patients with presumed mild to very severe COPD according to criteria of the Global Initiative for Chronic Obstructive Lung disease [GOLD]. Patients' follow-up-visits occurs at 6-month intervals; their history, symptoms and examination status is recorded. Data is entered into an online database either by the physicians or by study team after receiving the collected data questionnaires by facsimile. Data collection includes demographic data, physical examination, spirometric parameters, medical treatment and exacerbation history besides death. A spirometer (EasyOne™, ndd Medizintechnik AG, Zürich, Switzerland) is used to assess lung function. All participating physicians were instructed on the usage of the spirometer and on how to complete spirometry according to the guidelines. For the assessment of the severity of COPD, we use the spirometric data provided by the GPs. The COPD severity is interpreted according to criteria of the GOLD committee. 3.2 Patient population Patients with newly diagnosed or existing COPD, who are managed in primary-care practices. 3.3 Inclusion criteria Tiffenau (FEV17FVC) < 70 without reversibility (Increase in FEV1 after inhalation of a bronchodilator <200 ml and <12%).
