BACKGROUND: Rheumatoid arthritis (RA) is often preceded by symptomatic phases during which classification criteria are not fulfilled. The health burden of these "at-risk" stages is not well described. This study assessed health-related quality of life (HRQoL), function, fatigue and depression in newly presenting patients with clinically suspect arthralgia (CSA), unclassified arthritis (UA) or RA. METHODS: Cross-sectional analysis of baseline Patient-Reported Outcome Measures (PROMs) was conducted in patients from the Birmingham Early Arthritis Cohort...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disorder with systemic consequences that can cause a muscle loss phenotype (MLP), which is characterized by the loss of muscle mass, muscle strength, or loss of both muscle and fat mass. There are limited data comparing the individual traits of MLP with clinical outcomes in a large unbiased cohort of COPD patients. Our aim was to determine the proportion of patients who met criteria for MLP in an unbiased sample of COPD patients at the population-level...

OBJECTIVE: The aim of this study was to assess the postural balance in COPD patients with obstructive sleep apnoea (OSA). Physical activity, anxiety and depression symptoms, mood, and falls were also assessed in this population. METHODS: Moderate to severe COPD patients were assessed for laboratory and clinical postural balance (force platform and mini-balance evaluation systems test (Mini-BESTest)), physical activity (accelerometry), OSA (polysomnography), sleep quality (Pittsburgh Sleep Quality Index), sleepiness (Epworth Sleepiness Scale), anxiety and depression symptoms (Hospital Anxiety and Depression Scale), dyspnoea (modified Medical Research Council), clinical status (COPD Assessment Test) and mood (Brunel Mood Scale)...

Chronic obstructive pulmonary disease (COPD) is a chronic, progressive and debilitating disease that affects quality of life (QOL), especially among patients living in poor environments. 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 Inflammatory markers are elevated in chronic obstructive pulmonary disease (COPD) and can be quantified to detect severity, prognosis, mortality risk, and response to treatment. However, the estimation costs are high. The blood neutrophil-to-lymphocyte ratio (NLR) and eosinophil levels are emerging as biomarkers in COPD, yet there is a paucity of data. Aim and objectives This study was designed to elucidate the roles of the NLR and eosinophil levels in smokers and non-smokers with stable COPD male subjects, correlating them with lung functions...

RATIONALE: According to GOLD, the ratio of FEV1 /FVC is used to confirm airflow obstruction in COPD diagnosis, whereas FEV1 % of predicted (FEV1 %pred) is used for severity grading. STaging of Airflow obstruction by the FEV1 /FVC Ratio (STAR) and its prediction of adverse outcomes has not been evaluated in general populations. OBJECTIVE: To compare the STAR (FEV1 /FVC) versus GOLD (FEV1 %pred) classification for the severity of airflow limitation in terms of exertional breathlessness and mortality in the general US population...

Background . The significance of concomitant tricuspid regurgitation (TR) in the context of transcatheter aortic valve replacement (TAVR) remains unclear. This study aimed to analyze the severity of TR before and after TAVR with regard to short- and long-term survival and to analyze the influencing factors. Methods . In our retrospective analysis, TR before and after TAVR was examined and patients were classified into groups accordingly. Special attention was paid to patients with post-interventional changes in TR...

A 75-year-old man with type 2 diabetes and a history of previous empyema surgery was admitted to our hospital due to difficulty moving caused by chronic obstructive pulmonary disease and dehydration. During the first two days of hospitalization, intestinal myiasis was diagnosed after maggots were found in his diapers. After the maggots disappeared, he developed a fever, prompting antibiotic therapy for a suspected secondary infection, resulting in clinical improvement. Despite thorough home cleaning, no flies or maggots were found, and the source of infection and the fly species remained unknown...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) affecting 334 million people in the world remains a major cause of morbidity and mortality. Proper diagnosis of COPD is still a challenge and largely solely based on spirometric criteria. We aimed to investigate the potential of nitrosative/oxidative stress and related metabolic biomarkers in exhaled breath condensate (EBC) to discriminate COPD patients. METHODS: Three hundred three participants were randomly selected from a 15,000-transit worker cohort within the Respiratory disease Occupational Biomonitoring Collaborative Project (ROBoCoP)...

BACKGROUND: Mortality due to chronic obstructive pulmonary disease (COPD) is increasing. However, dead space fractions at rest (VD /VTrest ) and peak exercise (VD /VTpeak ) and variables affecting survival have not been evaluated. This study aimed to investigate these issues. METHODS: This retrospective observational cohort study was conducted from 2010-2020. Patients with COPD who smoked, met the Global Initiatives for Chronic Lung Diseases (GOLD) criteria, had available demographic, complete lung function test (CLFT), medication, acute exacerbation of COPD (AECOPD), Charlson Comorbidity Index, and survival data were enrolled...

Introduction Pulmonary hypertension (PH) is a recognized complication in patients with end-stage renal disease (ESRD undergoing maintenance hemodialysis (MHD). PH is commonly found in patients with chronic kidney disease (CKD) and ESRD. PH is associated with increased morbidity and mortality in patients with CKD. Methodology This cross-sectional study aimed to assess the prevalence of PH and its associated risk factors in MHD patients. A total of 220 ESRD patients on MHD patients at The Kidney Center, Karachi, Pakistan, aged 18-70 were included...

BACKGROUND: Body composition changes are important extrapulmonary manifestations in chronic obstructive pulmonary disease (COPD) patients. This study aimed to investigate the characteristics of body composition in patients with COPD, and its correlation with disease severity. METHODS: A total of 105 COPD patients admitted to Zhongshan Hospital affiliated to Dalian University, from May 1, 2021 to January 31, 2023, were included as the COPD group, and 105 subjects without COPD were enrolled as the control group during the same period...

BACKGROUND: Cardiovascular comorbidities are increasingly being recognised in early stages of chronic obstructive pulmonary disease (COPD) yet complete cardiorespiratory functional assessments of individuals with mild COPD or presenting with COPD risk factors are lacking. This paper reports on the effectiveness of the cardiocirculatory-limb muscles oxygen delivery and utilisation axis in smokers exhibiting no, or mild to moderate degrees of airflow obstruction using standardised cardiopulmonary exercise testing (CPET)...

Notch signaling is involved in the prevention of cell differentiation and cell fate in various organs, including the lungs. We aimed to determine the transcriptomic and protein expression of Notch receptors, their ligands, and related transcription factors in stable COPD. The expression and localization of Notch receptors, their ligands, and related transcription factors were measured in bronchial biopsies of individuals with stable mild/moderate (MCOPD) (n = 18) or severe/very severe (SCOPD) (n = 16) COPD, control smokers (CSs) (n = 13), and control nonsmokers (CNSs) (n = 11), and in the lung parenchyma of those with MCOPD (n = 13), CSs (n = 10), and CNSs (n = 10) using immunohistochemistry, ELISA tests, and transcriptome analyses...

Background and Objectives : Severe adult-onset eosinophilic asthma and COPD with eosinophilic inflammation are two entities with a similar clinical course and are sometimes difficult to differentiate in clinical practice, especially in patients with a history of smoking. Anti-IL-5 or -IL-5R biological therapy has been shown to be highly effective in severe eosinophilic asthma but has not demonstrated significant benefit in patients with COPD with the eosinophilic phenotype. Our aim was to illustrate this issue in the form of a case report...

BACKGROUND: Recent guidelines for spirometry interpretation recommend both race-neutral reference equations and use of z-score thresholds to define severity of airflow obstruction. RESEARCH QUESTION: How does the transition from race-specific to race-neutral equations impact severity classifications for patients with COPD when using percent-predicted versus z-score thresholds, and do changes in severity correspond to clinical risk? STUDY DESIGN AND METHODS: This retrospective cohort study included Black and White patients with COPD and available spirometry from the Johns Hopkins Health System...

INTRODUCTION: Endoscopic Lung Volume Reduction (ELVR) with endobronchial valves has been widely recognized for treating hyperinflation in advanced COPD and emphysema patients. The main challenges include the technical complexity of upper lobe implantation and the number of endobronchial valves required. These issues might be addressed by placing larger-diameter valves in the lobar bronchus. This study evaluated the feasibility, efficiency, and safety of the new valve PulmValve (model PV-13) in porcine models...

BACKGROUND AND OBJECTIVE: This study investigated changes in retinal nerve fiber layers (RNFL) in patients diagnosed with chronic obstructive pulmonary disease (COPD) compared to healthy control patients, using optical coherence tomography. METHODS: PubMed, Cochrane Library, and Google Scholar databases were systematically searched for published articles comparing RNFL between patients with COPD and healthy controls. Standardized mean difference (SMD) with 95% confidence interval (CI) was computed to compare continuous variables...

INTRODUCTION: Chronic lung disease (CLD) has been associated with risk for more severe manifestations and death with COVID-19. However, few studies have evaluated the risk overall and by type of CLD for severity of COVID-19 outcomes in a US national cohort. METHODS: Using data from the Veterans Health Administration, we determined the risk associated with CLDs including COPD (mild/severe), asthma (mild/active/severe), idiopathic pulmonary fibrosis (IPF), sarcoidosis and other interstitial lung diseases (ILDs) for outcomes among veterans with SARS-CoV-2 positive tests between 3/1/2020-4/30/2021...
