chronic total obstruction

Atrial fibrillation/flutter (AF) is the most common dysrhythmia in patients with hypertrophic cardiomyopathy (HCM). Unexplained left ventricular hypertrophy and left ventricular outflow tract (LVOT) obstruction are integral components of HCM pathology which can cause increased left atrial pressure and atrial myopathy contributing to the substrate for AF. Our aim was to determine the impact of AF on hospital readmissions in patients with HCM. We conducted a retrospective analysis using the 2015 - 2019 Nationwide Readmission Database to analyze the effect of AF on 30-day readmission and causes of 30-day readmission in patients with HCM...

BACKGROUND: Airway remodeling is a significant pathological characteristic of chronic obstructive pulmonary disease (COPD). In recent years, hypoxia-inducible factor 1-α (HIF-1α), a member of the hypoxia-inducible factor protein family, has gained attention. However, the potential correlation between HIF-1α and COPD airway remodeling remains unclear. OBJECTIVE: This study explored the expression patterns of HIF-1α in patients with COPD and its association with airway remodelling...

Electronic cigarettes (or e-cigarettes) and vape products have multisystemic adverse effects despite being advertised as a safer smoking alternative and cessation device. We present a 22-year-old Filipino male with sudden chest pain. He had no known comorbidities but had a two-year history of daily vape use. Work-up revealed elevated cardiac markers, anteroseptal ST-elevation myocardial infarction, hypokinesia of the anterior wall and interventricular septum, and an ejection fraction of 30%. Chest radiography showed consolidation pneumonia but culture studies and Biofire Pneumonia Panel were negative for microbial detection...

BACKGROUND: The carbon footprint of Canada's health sector is among the worst in the world, responsible for 4·6% of Canada's total greenhouse gas emissions. A quarter of emissions from Canada's health sector are linked to pharmaceuticals, including metered dose inhalers (MDIs). MDIs use propellants, such as hydrofluorocarbons, which act as greenhouse gas emissions and contribute to the health-care sector's overall carbon footprint. The objective of this study was to describe MDI prescribing, dispensing, usage, and waste patterns at The Ottawa Hospital (Ottawa, ON, Canada)...

Chronic obstructive pulmonary disease (COPD) is a frequent cause of morbidity and mortality in the Philippines and majority of the economic burden lies in hospitalizations during an exacerbation. Despite coverage of hospitalization cost with the national health insurance system (Phil-Health) for COPD exacerbations, patients often pay out-of-pocket. This study aimed to determine the demographic characteristics of COPD admissions at a Philippine tertiary care center, Philippine General Hospital, and assess mean cost of hospitalization, and identify predictors of prolonged hospitalization and cost > 20,000 Philippine pesos (Php)...

BACKGROUND: Anxiety is common in patients with chronic obstructive pulmonary disease (COPD). However, there is little evidence available regarding gender differences, and severity of dyspnea in relation to anxiety in patients with COPD. AIMS: We examined gender differences and the association of dyspnea with anxiety in a cohort of patients with COPD prior to entering a pulmonary rehabilitation (PR) program. METHOD: We analyzed data from a prospective cohort of COPD patients who attended PR from 2013 to 2019 in Lytham, Lancashire, UK...

Although several occupational exposures have been linked to the risk of COPD; limited data exists on sex-specific differences. This study aimed to identify at-risk occupations and sex differences for COPD risk. Cases were identified in a large surveillance system established through the linkage of former compensation claimants' data (non-COPD claims) to physician visits, ambulatory care data, and hospital inpatient data (1983-2020). Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CI) for occupation groups (occupation at time of claim), stratified by sex...

BACKGROUND: The objective of this study was to determine whether the concomitant presence of poor health status (COPD Assessment Test, CAT ≥ 10 points) and low exercise tolerance (6-Minute Walking Test, 6MWT < 350 m) is associated with worse clinical characteristics in patients with COPD. In addition, we aimed to develop a readily applicable diagnostic model to discriminate COPD patients with these conditions. METHODS: A cross-sectional multicenter study involving 208 stable COPD patients (FEV1/FVC < 0...

RATIONALE: Although numerous candidate features exist for predicting risk of higher risk of healthcare utilization in patients with chronic obstructive pulmonary disease (COPD), the process for selecting the most discriminative features remains unclear. OBJECTIVE: The objective of this study was to develop a robust feature selection method to identify the most discriminative candidate features for predicting healthcare utilization in COPD, and compare the model performance with other common feature selection methods...

BACKGROUND: The incidence of chronic obstructive pulmonary disease (COPD) and osteoporosis are rising worldwide. Observational studies showed that COPD is associated with increased risk of osteoporosis. We performed the Mendelian randomization (MR) study to genetically investigate the causality of COPD on osteoporosis. METHODS: We explored the causal effect of COPD on osteoporosis by the MR analysis. A total of 108 genetic loci single nucleotide polymorphisms were related to COPD...

OBJECTIVE: To establish an efficient nomogram model to predict short-term survival in ICU patients with aplastic anemia (AA). METHODS: The data of AA patients in the MIMIC-IV database were obtained and randomly assigned to the training set and testing set in a ratio of 7:3. Independent prognosis factors were identified through univariate and multivariate Cox regression analyses. The variance inflation factor was calculated to detect the correlation between variables...

Chronic Obstructive Pulmonary Disease (COPD) is characterized by progressive and irreversible airflow limitation, with individual body composition influencing disease severity. Severe emphysema worsens symptoms through hyperinflation, which can be relieved by bronchoscopic lung volume reduction (BLVR). To investigate how body composition, assessed through CT scans, impacts outcomes in emphysema patients undergoing BLVR. Fully automated CT-based body composition analysis (BCA) was performed in patients with end-stage emphysema receiving BLVR with valves...

This study aimed to determine the influencing factors of good QOL among COPD patients living in Zhejiang, China. A cross-sectional study was conducted to collect data from participants in six tertiary hospitals in Zhejiang Province by a simple random sampling method. A validated questionnaire was used to collect general information, environmental factors, and COPD stage...

BACKGROUND: There are not enough GPs in England. Access to general practice and continuity of care are declining. AIM: To investigate whether practice characteristics are associated with life expectancy of practice populations. DESIGN AND SETTING: A cross-sectional ecological study of patient life expectancy from 2015-2019. METHOD: Selection of independent variables was based on conceptual frameworks describing general practice's influence on outcomes...

Background Pulmonary rehabilitation (PR) is an integral part of non-pharmacological therapy in chronic obstructive pulmonary disease (COPD). Yoga therapy (YT) has been shown to be beneficial in COPD, but the lack of large well-designed trials and standardized modules restricts its acceptability. This randomized control trial compares these two modalities in COPD patients via supervised tele-intervention. Objectives The primary objective of the study is to compare a 45-minute, five-days-per-week series of tele-YT (T-YT) with tele-PR (T-PR) for three months in terms of exercise capacity (6-Minute Walk Distance (6MWD)) in COPD patients...

Background and aim Nasal obstruction is one of the most common reasons for consultation addressed by otolaryngologists. There are anatomical, physiological, and pathological etiologies. Sometimes the treatment can become a challenge for the specialist, so a detailed evaluation of the etiologies must be carried out. The involvement of the nasal vestibular body (NVB) in obstructive symptoms has been described. Therefore, we must be familiar with its anatomy, presentation, and contribution to this symptomatology...

BACKGROUND: Long-standing controversy has existed over whether sublobar resection is an adequate oncological procedure for clinical stage IA non-small cell lung cancer (NSCLC) ≤2 cm, despite the recent randomized trial reports of Japanese Clinical Oncology Group (JCOG) 0802 and Cancer and Leukemia Group B (CALGB) 140503 demonstrating non-inferior outcomes with sublobar resection compared to lobectomy. As practice patterns shift, we sought to compare oncologic outcomes in patients with these early-stage tumors after wedge resection, segmentectomy, or lobectomy in a contemporary, real-world, cohort...
