Abstract
Poland is a country with a high burden of COPD and its risk factors. This population-wide and geospatial study on COPD in Poland, aimed to analyze changes in hospitalizations of patients with a diagnosis of COPD between 2006 and 2019 as well as to identify changes in the demographic characteristics of patients hospitalized with COPD. This is a retrospective analysis of hospital discharge records of patients with a diagnosis of COPD (ICD-10 code J44 and age 40 and over), hospitalized in Poland between 2006 and 2019. Data were analyzed separately for all patients hospitalized with COPD (primary and secondary diagnosis), for patients admitted due to COPD (primary diagnosis) and patients hospitalized with COPD as a comorbidity (secondary diagnosis). Between 2006 and 2019, a total of 1,663,420 hospital admissions of patients with COPD were reported. Between 2006 and 2019, the annual number of patients hospitalized due to COPD decreased by 53.8%, including 57.3% among men and 46.6% among women. The number of patients hospitalized with COPD as comorbidity increased by 35.8%. The lowest hospital admissions rate was in north-western Poland and the highest in north-eastern Poland. Among patients admitted due to COPD, the percentage of women increased from 32.6% to 37.7%. The percentage of patients admitted due to COPD and living in rural areas decreased from 51.2% in 2006 to 40.8%in 2019. This study provided data on changes in sociodemographic characteristics of hospitalizations of patients with a diagnosis of COPD, including overall reduction in COPD admissions but an increase in COPD burden among women.

Abstract
This article summarises key themes from a symposium held during the recent European Respiratory Society congress, which took place in Vienna, Austria, 7-11 September 2024. The symposium was sponsored by GSK and entitled 'Striving for disease stability in COPD: Giving patients more of their best days'. During the session, the speakers (MeiLan Han, Lowie Vanfleteren and Dave Singh) highlighted the specific challenges of chronic obstructive pulmonary disease (COPD), such as its unpredictable and unstable nature, with additional insights provided from patients with COPD in the form of video interviews. The faculty discussed whether treatment standards and goals should be more ambitious to provide all patients the stability and predictability they deserve and the opportunity to do more while living with COPD.

Abstract
PURPOSE OF REVIEW To provide timely and relevant insights into the complex relationship between pulmonary vascular disease (PVD) and chronic lung disease (CLD), focusing on the causative and consequential dynamics between these conditions. RECENT FINDINGS There are shared pathogenic mechanisms between pulmonary arterial hypertension (PAH) and group 3 pulmonary hypertension, including altered expression of mediators and growth factors implicated in both conditions. Factors such as hypoxia, hypoxemia, and hypercapnia also contribute to pulmonary vascular remodelling and endothelial dysfunction. However, the role of hypoxia as the sole driver of pulmonary hypertension in CLD is being reconsidered, particularly in chronic obstructive pulmonary disease (COPD), with evidence suggesting a potential role for cigarette smoke products in initiating pulmonary vascular impairment. On the other hand, interstitial lung disease (ILD) encompasses a group of heterogeneous lung disorders characterized by inflammation and fibrosis of the interstitium, leading to impaired gas exchange and progressive respiratory decline, which could also play a role as a cause of pulmonary hypertension. SUMMARY Understanding the intricate interplay between the pulmonary vascular compartment and the parenchymal and airway compartments in respiratory disease is crucial for developing effective diagnostic and therapeutic strategies for patients with PVD and CLD, with implications for both clinical practice and research.

Abstract
Importance Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Observational studies report that β-blocker use may be associated with reduced risk of COPD exacerbations. However, a recent trial reported that metoprolol did not reduce COPD exacerbations and increased COPD exacerbations requiring hospital admission. Objective To test whether bisoprolol decreased COPD exacerbations in people with COPD at high risk of exacerbations. Design, Setting, and Participants The Bisoprolol in COPD Study (BICS) was a double-blind placebo-controlled randomized clinical trial conducted in 76 UK sites (45 primary care clinics and 31 secondary clinics). Patients with COPD who had at least moderate airflow obstruction on spirometry (ratio of forced expiratory volume in the first second of expiration [FEV1] to forced vital capacity <0.7; FEV1 <80% predicted) and at least 2 COPD exacerbations treated with oral corticosteroids, antibiotics, or both in the prior 12 months were enrolled from October 17, 2018, to May 31, 2022. Follow-up concluded on April 18, 2023. Interventions Patients were randomly assigned to bisoprolol (n = 261) or placebo (n = 258). Bisoprolol was started at 1.25 mg orally daily and was titrated as tolerated during 4 sessions to a maximum dose of 5 mg/d, using a standardized protocol. Main Outcomes and Measures The primary clinical outcome was the number of patient-reported COPD exacerbations treated with oral corticosteroids, antibiotics, or both during the 1-year treatment period. Safety outcomes included serious adverse events and adverse reactions. Results Although the trial planned to enroll 1574 patients, recruitment was suspended from March 16, 2020, to July 31, 2021, due to the COVID-19 pandemic. Two patients in each group were excluded postrandomization. Among the 515 patients (mean [SD] age, 68 [7.9] years; 274 men [53%]; mean FEV1, 50.1%), primary outcome data were available for 514 patients (99.8%) and 371 (72.0%) continued taking the study drug. The primary outcome of patient-reported COPD exacerbations treated with oral corticosteroids, antibiotics, or both was 526 in the bisoprolol group, with a mean exacerbation rate of 2.03/y, vs 513 exacerbations in the placebo group, with a mean exacerbation rate of 2.01/y. The adjusted incidence rate ratio was 0.97 (95% CI, 0.84-1.13; P = .72). Serious adverse events occurred in 37 of 255 patients in the bisoprolol group (14.5%) vs 36 of 251 in the placebo group (14.3%; relative risk, 1.01; 95% CI, 0.62-1.66; P = .96). Conclusions and Relevance Among people with COPD at high risk of exacerbation, treatment with bisoprolol did not reduce the number of self-reported COPD exacerbations requiring treatment with oral corticosteroids, antibiotics, or both.

Abstract
INTRODUCTION Proactive tobacco treatment programs are an evidence-based strategy to recruit patients who smoke to make supported quit attempts. However, such programs are rarely implemented. We performed a qualitative assessment of clinicians to inform the creation of a proactive outreach program for patients with chronic obstructive pulmonary disease (COPD) who smoke. METHODS Informed by the Consolidated Framework for Implementation Research, we conducted semi-structured interviews to assess clinician views of proactive outreach, including barriers, program structure, and the use of technology. Clinicians included primary and specialty care physicians, nurses and advanced practice providers, pharmacists, respiratory therapists, a psychologist, and relevant members of leadership. Interviews were transcribed and analyzed using directed content analysis. RESULTS Clinicians in all roles identified that proactive outreach could be an effective use of resources to help patients with COPD who smoke quit with several advantages over the current state. Clinicians disagreed on the priority population (e.g., younger patients, sicker patients), and to some extent on whether proactive outreach is a clinical priority. Though they supported that technology could be part of the outreach program, most advocated for multiple avenues (phone calls, drop-in clinic, texting), as these patients were perceived to be low technology utilizers. The primary implementation barriers were competing priorities and cost, as well as unclear billing and staffing models. CONCLUSIONS Clinicians support proactive outreach for patients with COPD, but the optimal way to structure, staff, and fund such programs remains unclear. Health systems should leverage implementation strategies to speed uptake of these potentially life-saving programs.

Abstract
Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder characterized by enduring airflow limitation and chronic inflammation. Growing evidence highlights mitochondrial dysfunction as a critical factor in COPD development and progression. This review explores the cellular and molecular biology of mitochondria in COPD, focusing on structural and functional changes, including alterations in mitochondrial shape, behavior, and respiratory chain complexes. We discuss the impact on cellular signaling pathways, apoptosis, and cellular aging. Therapeutic strategies targeting mitochondrial dysfunction, such as antioxidants and mitochondrial biogenesis inducers, are examined for their potential to manage COPD. Additionally, we consider the role of mitochondrial biomarkers in diagnosis, evaluating disease progression, and monitoring treatment efficacy. Understanding the interplay between mitochondrial biology and COPD is crucial for developing targeted therapies to slow disease progression and improve patient outcomes. Despite advances, further research is needed to fully elucidate mitochondrial dysfunction mechanisms, discover new biomarkers, and develop targeted therapies, aiming for comprehensive disease management that preserves lung function and enhances the quality of life for COPD patients.

[PMID: 38627182 DOI: 10.1016/j.ejim.2024.03.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Revised: 03/25/2024] [Accepted: 03/28/2024] [Indexed: 07/04/2024]
Abstract
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 < 0.7, smoking history of at least 10 pack-years, and chronic respiratory symptoms) was carried out. The outcome measures were the 6MWT, CAT score, 5-repetition sit-to-stand test (5STS) and modified Medical Research Council Dyspnea Scale (mMRC). Patients were categorized into three groups: no condition (6MWT ≥ 350 m and CAT < 10 points), one condition (6MWT < 350 m or CAT ≥ 10 points), and both conditions (6MWT < 350 m and CAT ≥ 10 points). RESULTS A total of 26 patients (12,5%) presented both conditions. These patients experienced a higher degree of dyspnea (p = 0.001), smoking pack-years (p = 0.011), severe obstruction (p = 0.006), and time on 5STS (p = 0.001). The probability of having both conditions directly increased with the time spent on the 5STS (β=0.188; p = 0.010) and the degree of dyspnea (β=1.920; p < 0.001) (R2=0.413). The scoring system, using the 5STS and dyspnea as surrogate measures, demonstrated adequate calibration between the predicted and observed risk (linear R2=0.852). CONCLUSIONS COPD patients with concurrent conditions have worse clinical status. The diagnostic model developed to discriminate these patients shows good internal validation.

Abstract
INTRODUCTION The EXAcerbations of Chronic obstructive lung disease (COPD) and their OutcomeS (EXACOS) International Study aimed to quantify the rate of severe exacerbations and examine healthcare resource utilisation (HCRU) and clinical outcomes in patients with COPD from low-income and middle-income countries. METHODS EXACOS International was an observational, cross-sectional study with retrospective data collection from medical records for a period of up to 5 years. Data were collected from 12 countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Guatemala, Hong Kong, Mexico, Panama, Russia and Taiwan. The study population comprised patients ≥40 years of age with COPD. Outcomes/variables included the prevalence of severe exacerbations, the annual rate of severe exacerbations and time between severe exacerbations; change in lung function over time (measured by the forced expiratory volume in 1 s (FEV1)); peripheral blood eosinophil counts (BECs) and the prevalence of comorbidities; treatment patterns; and HCRU. RESULTS In total, 1702 patients were included in the study. The study population had a mean age of 69.7 years, with 69.4% males, and a mean body mass index of 26.4 kg/m2. The mean annual prevalence of severe exacerbations was 20.1%, and 48.4% of patients experienced ≥1 severe exacerbation during the 5-year study period. As the number of severe exacerbations increased, the interval between successive exacerbations decreased. A statistically significant decrease in mean (SD) FEV1 from baseline to post-baseline was observed in patients with ≥1 severe exacerbation (1.23 (0.51) to 1.13 (0.52) L; p=0.0000). Mean BEC was 0.198 x109 cells/L, with 64.7% of patients having a BEC ≥0.1 x109 cells/L and 21.3% having a BEC ≥0.3 x109 cells/L. The most common comorbidity was hypertension (58.3%). An increasing number of severe exacerbations per year was associated with greater HCRU. DISCUSSION The findings presented here indicate that effective treatment strategies to prevent severe exacerbations in patients with COPD remain a significant unmet need in low-income and middle-income countries.

Ang BW, Fernandez L. A prospective study on direct out-of-pocket expenses of hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease in a Philippine tertiary care center. BMC Pulm Med 2024; 24:184. [PMID: 38632584 PMCID: PMC11022336 DOI: 10.1186/s12890-024-03011-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Accepted: 04/11/2024] [Indexed: 04/19/2024] Open
Abstract
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). A prospective cross-sectional study was conducted for 6 months by chart review. Patients were categorized as charity service patients, that is, with no charged professional fees and free medications and private service patients who pay for their health care services. A total of 43 COPD admissions were included. The average daily cost of hospitalization (at peso-dollar rate of 56) for service patients was at $ 75.89 compared to private service patients at $ 285.71. Demographic characteristics and type of accommodation were not significant predictors of prolonged hospital stay nor hospitalization cost of ≥ $ 357. Accommodation cost and professional fees accounted for majority or 61.6% of the overall cost for private patients, while medications and diagnostic tests were the major or 76.01% contributor to the overall cost for charity patients. Despite existence of Phil-health, in-patient coverage for COPD remain insufficient. Measures for maximizing COPD control in the out-patient setting could potentially reduce total cost for this disease.

Yang K, Chen R. Association between cooking fuel exposure and respiratory health: Longitudinal evidence from the China Health and Retirement Longitudinal Study (CHARLS). ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 275:116247. [PMID: 38520808 DOI: 10.1016/j.ecoenv.2024.116247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 03/19/2024] [Accepted: 03/20/2024] [Indexed: 03/25/2024]
Abstract
The epidemiological evidences for the association between cooking fuel exposure and respiratory health were inconsistent, and repeated-measures prospective evaluation of cooking fuel exposure was still lacking. We assessed the longitudinal association of chronic lung disease (CLD) and lung function with cooking fuel types among Chinese adults aged ≥ 40 years. In this prospective, nationwide representative cohort of the China Health and Retirement Longitudinal Study from 2011 to 2018, 9004 participants from 28 provinces in China were included. CLD was identified based on self-reported physician diagnosis in 2018. Lung function was assessed by peak expiratory flow (PEF) in 2011, 2013 and 2015. Multivariable logistic and linear mixed-effects repeated-measures models were conducted to measure the associations of CLD and PEF with cooking fuel types. Three-level mixed-effects model was performed as sensitivity analysis. Among the participants, 3508 and 3548 participants used persistent solid and clean cooking fuels throughout the survey, and 1948 participants who used solid cooking fuels at baseline switched to clean cooking fuels. Use of persistent clean cooking fuels (adjusted odds ratio [aOR] = 0.73, 95 % confidence interval [CI]: 0.61, 0.88) and switch of solid fuels to clean fuels (aOR = 0.81, 95 % CI: 0.67, 0.98) were associated with lower risk of CLD. The use of clean cooking fuels throughout the survey and switch of solid fuels to clean fuels in 2013 were also significantly associated with higher PEF level. Similar results were observed in stratified analyses and different statistical models. The evidence from CHARLS cohort suggested that reducing solid cooking fuel exposure was associated with lower risk of CLD and better lung function. Given the recent evidence, improving household air quality will reduce the burden of chronic lung diseases.

Abstract
PURPOSE Immunoglobulin replacement therapy is a standard treatment for patients with antibody production deficiencies, which is of interest in patients with chronic obstructive pulmonary disease (COPD). This systematic review, registered with PROSPERO (CRD42021281118), assessed the current literature regarding immunoglobulin replacement therapy on COPD clinical outcomes in patients with low immunoglobulin G (IgG) serum concentrations. METHODS Literature searches conducted from inception to August 23, 2021, in databases including MEDLINE, EMBASE, and CINAHL. Population (sex, age, comorbidities), baseline clinical characteristics (pulmonary function testing results, IgG levels), and outcome (hospitalizations, emergency department visits) were extracted after title/abstract and full text screening. The Cochrane risk of bias assessment form was used for risk of bias assessment of randomized controlled trials and the National Heart, Lung, and Blood Institute (NHLBI) assessment was used for pre and post studies. RESULTS A total of 1381 studies were identified in the preliminary search, and 874 records were screened after duplicates were removed. Screening 77 full texts yielded four studies that were included in the review. CONCLUSION It is unclear whether immune globulin replacement therapy reduces acute exacerbation frequency and severity in COPD. Current evidence suggests that it is worth considering, but better developed protocols for administration of immune globulin supplementation is required for future randomized controlled trials.

Abstract
The six-minute step test (6MST) has been shown to be effective in assessing exercise capacity in individuals with COPD regardless of severity and, despite its easy execution, accessibility and validity, information on the prognostic power of this test remains uncertain. The aim of this study is to investigate whether the 6MST can predict the occurrence of exacerbations in patients with COPD. This is a prospective cohort study with a 36-month follow-up in patients with COPD. All patients completed a clinical assessment, followed by pulmonary function testing and a 6MST. The 6MST was performed on a 20 cm high step; heart rate, blood pressure, oxygen saturation, BORG dyspnea and fatigue were collected. Sixty-four patients were included in the study, the majority being elderly men. Performance on the 6MST demonstrated lower performance compared to normative values proposed in the literature, indicating a reduced functional capacity. Kaplan Meier analysis revealed that ≤ 59 steps climbed during the 6MST was a strong predictor of COPD exacerbation over a 36-month follow-up. We have identified a minimal threshold number of steps (≤ 59) obtained through the 6MST may be able predict the risk of exacerbations in patients with COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) can negatively affect patients' employment and work-life activities with a significant indirect economic impact. The current study aimed to measure unemployment, work productivity, activity impairment, and their associated factors among COPD patients. A cross-sectional study was conducted in the Chest outpatient clinic, Mansoura University Hospital, Egypt. COPD patients completed an interviewer-administered questionnaire including sociodemographic, occupational data, clinical history, medical research council (mMRC) dyspnea scale, the COPD assessment test (CAT), and work productivity and activity impairment Questionnaire (WPAI-COPD). A total 140 patients were included in the study and 22.1% of them gave up their jobs because of their COPD. Due to COPD, the mean percentage of daily activity impairment was 39.8 among all patients. The mean percentages of absenteeism, presenteeism, and overall work impairment among the 84 working patients were 0.07, 24.4, and 24.5. The CAT score was the significant predictor of all components of WPAI. In conclusion, COPD causes early retirement, high work productivity loss, and impaired daily activities. Higher CAT scores and increased disease severity significantly increase absenteeism, presenteeism, overall work, and activity impairment. Thus, timely diagnosis of COPD with appropriate management can help improve outcomes and lower the disease burden and economic impact.

Abstract
Chronic obstructive pulmonary disease (COPD) is a preventable yet widespread and profoundly debilitating respiratory condition, exerting substantial personal and global health ramifications alongside significant economic implications. The first objective of this literature review was to identify reviews the barriers to optimal COPD care, categorizing them into personal patient factors, professional awareness and knowledge, patient-professional relationships, and healthcare service models, including access to care that significantly impacts the quality of COPD management. The second objective was to introduce three approaches for enhancing COPD care outcomes: Self-Management Educational Programs, Health Qigong, and Telehealth service provision, each demonstrating positive effects on COPD patients' health status. These evidence-based interventions offer promising avenues for enhancing COPD care and patient outcomes. Integrating these approaches into comprehensive COPD management strategies holds potential for improving the well-being and quality of life of individuals living with this chronic condition.

Abstract
Chronic obstructive pulmonary disease (COPD) carries an important economic burden worldwide. However, the cost of this disease in Morocco is not well explored. This study aimed to estimate the economic cost associated with COPD in Morocco and identify its determinants. A cost of illness, prevalence-based study using a bottom-up approach method, including COPD patients, was carried out in 2021-2022. The cost was estimated from a societal perspective, and the time horizon was 1 year. Data collection was performed using a questionnaire including socio-demographic, clinical data, and utilization of health care resources in 2019: hospitalization, medical tests, medications, and medical visits. Direct health cost (DHC) was estimated by multiplying the use of health services by the official prices (unit costs) published by the National Agency for Health Insurance. The indirect cost (IC) represented by labor productivity losses was calculated using the human capital method. Costs were compared according to different socio-demographic and clinical factors. We included 159 patients; 82.4% were men, 80.4% were current or former smokers, and 78.7% were categorized as "high-risk" groups (grades C-D). The DHC was estimated at $1816.6 per patient per year. Pharmaceutical and hospitalization costs represented the highest part of the total DHC (42.5% and 22.1%, respectively). The IC was estimated at $709.5±1081.3 per patient per year. DHC increased with increasing disease severity and with the number of severe exacerbations (p<0.001). Current and former smokers were more costly to the healthcare system than nonsmokers (p=0.029). IC also increased with the number of severe exacerbations (p=0.003). In this study, we showed that COPD in Morocco generates important costs for the health system, mainly related to smoking and the severity of the disease. It is therefore important to strengthen tobacco control measures in our country.

Association Between Rome Classification Among Hospitalized Patients With COPD Exacerbations and Short-Term and Intermediate-Term Outcomes. Chest 2023; 164:1422-1433.

Abstract
BACKGROUND Recently, the Rome proposal updated the definition of exacerbation of COPD (ECOPD). However, such severity grade has not yet demonstrated intermediate-term clinical relevance. RESEARCH QUESTION What is the association between the Rome severity classification and short-term and intermediate-term clinical outcomes? STUDY DESIGN AND METHODS We retrospectively grouped hospitalized patients with ECOPD according to the Rome severity classification (ie, mild, moderate, severe). Baseline, clinical, microbiologic, gas analysis, and laboratory variables were collected. In addition, data about the length of hospital stay and mortality (in-hospital and a follow-up time line from 6 months until 3 years) were assessed. RESULTS Of the 347 hospitalized patients, 39% were categorized as mild, 31% were categorized as moderate, and 30% were categorized as severe. Overall, patients with severe ECOPD had an extended length of hospital stay. Although in-hospital mortality was similar among groups, patients with severe ECOPD presented a worse prognosis in all follow-up time points. The Kaplan-Meier curves show the role of the severe classification in the cumulative survival at 1 and 3 years (Gehan-Breslow-Wilcoxon test, P = .032 and P = .004, respectively). The multivariable Cox regression analysis showed a higher risk of death at 1 year when patients presented a severe (hazard ratio, 1.99; 95% CI, 1.49-2.65) or moderate grade (hazard ratio, 1.47; 95% CI, 1.10-1.97) compared with a mild grade. Older patients (aged ≥ 80 years), patients requiring long-term oxygen therapy, or patients reporting previous ECOPD episodes had a higher mortality risk. A BMI between 25 and 29 kg/m2 was associated with a lower risk. INTERPRETATION The Rome classification makes it possible to discriminate patients with a worse prognosis (severe or moderate) until a 3-year follow-up.

Abstract
A systematic review aimed to investigate the association between schizophrenia and bipolar disorder and chronic obstructive pulmonary disease (COPD), its prevalence and incidence, potential factors associated with its occurrence and its impact on mortality among these patients. We performed the literature search in PubMed, Scopus and PsycInfo from inception to February 2022 and identified 19 studies: ten cross-sectional, 5 that included cross-sectional and longitudinal analyses, and 4 retrospective cohort studies. The reported prevalence of COPD ranged from 2.6% to 52.7% in patients with schizophrenia and between 3.0% and 12.9% in patients with bipolar disorder. Two studies reported an annual incidence of COPD of 2.21 cases/100 person-years in patients with schizophrenia and 2.03 cases/100 person-years in patients with bipolar disorder. Among the risk factors evaluated in three studies, only advanced age was consistently associated with the presence/occurrence of COPD in patients with schizophrenia and bipolar disorder; the role of tobacco consumption was not investigated in those three studies. According to two studies, the likelihood of mortality from COPD showed an over 3-fold increase in patients with schizophrenia and a 2-fold increase in those with bipolar disorder compared to the overall population; COPD was also associated with increased inpatient mortality. Available data indicate that COPD in patients with schizophrenia and bipolar disorder is a major public health problem. National and international health organizations should strive to specifically address this issue by creating awareness about this health problem and developing specific programs for screening and early intervention aimed to reduce the burden of COPD in these populations.

Abstract
INTRODUCTION This study aimed to evaluate the modifying role of dietary fiber intake in the relationship between COPD and cognitive performance. METHODS Data of adults aged ≥60 years were extracted from the National Health and Nutrition Examination Survey (NHANES) 2011-2014. Participants with information on cognitive function measures were included. Dietary fiber intake, identified using participants' 24-h recall surveys, was grouped into high (>25 g/day) and low (≤25 g/day) levels. COPD was identified through self-reported physician diagnoses. Associations between dietary fiber intake, cognitive function and COPD were evaluated using the regression analysis. RESULTS Data of 2,189 participants were analyzed. Multivariate analysis revealed that COPD was significantly associated with lowered CERAD (adjusted beta [aBeta]: -0.17, 95% confidence interval [CI]: -0.33 to -0.002, p = .047) and DSST (aBeta: -2.23, 95% CI: -4.25 to -0.2, p = .032) scores in older adults. The analysis on the association between COPD and cognitive function stratified by dietary fiber intake revealed that COPD remained significantly associated with lowered CREAD among individuals with a high fiber intake (aBeta: -0.54, 95% CI: -1.00 to -0.08, p = .024). CONCLUSIONS In US older adults, COPD is associated with reduced cognitive function. However, the findings do not support that high dietary fiber intake may modify the association between COPD and cognitive impairment.

Abstract
Traditional respiratory rehabilitation training fails to achieve visualization and quantification of respiratory data in improving problems such as decreased lung function and dyspnea in people with respiratory disorders, and the respiratory rehabilitation training process is simple and boring. Therefore, this article designs a biofeedback respiratory rehabilitation training system based on virtual reality technology. It collects respiratory data through a respiratory sensor and preprocesses it. At the same time, it combines the biofeedback respiratory rehabilitation training virtual scene to realize the interaction between respiratory data and virtual scenes. This drives changes in the virtual scene, and finally the respiratory data are fed back to the patient in a visual form to evaluate the improvement of the patient's lung function. This paper conducted an experiment with 10 participants to evaluate the system from two aspects: training effectiveness and user experience. The results show that this system has significantly improved the patient's lung function. Compared with traditional training methods, the respiratory data are quantified and visualized, the rehabilitation training effect is better, and the training process is more active and interesting.

Pepin JL, Lemeille P, Denis H, Josseran A, Lavergne F, Panes A, Bailly S, Palot A, Prigent A. Health trajectories before initiation of non-invasive ventilation for chronic obstructive pulmonary disease: a French nationwide database analysis. THE LANCET REGIONAL HEALTH. EUROPE 2023; 34:100717. [PMID: 37927425 PMCID: PMC10625021 DOI: 10.1016/j.lanepe.2023.100717] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 07/21/2023] [Accepted: 08/01/2023] [Indexed: 11/07/2023]
Abstract
Background Chronic obstructive pulmonary disease (COPD) is the most common indication for long-term domiciliary non-invasive ventilation (NIV) but there is uncertainty in data supporting current guidelines. This study described health trajectories before initiation of at-home NIV in people with COPD, and compared mortality outcomes between groups with different pre-NIV health trajectories. Methods Data were from the French national health insurance reimbursement system database for individuals with COPD aged ≥40 years and ≥1 reimbursement for NIV between 1 January 2015 and 31 December 2019. Common health trajectories were determined using time sequence analysis through K-clustering (TAK analysis). Findings Data from 54,545 individuals were analysed; the population was elderly (median age 70 years) with multiple comorbidities. Four clusters were generated. Cluster 1 (n = 35,975/54,545; 66%) had NIV initiated in ambulatory settings or after the first acute event/exacerbation. Cluster 2 (6653/54,545; 12%) started NIV after ≥2 severe exacerbations in the previous 6 months. Cluster 3 (11,375/54,545; 21%) started NIV after frequent severe COPD-related exacerbations in the previous year. Cluster 4 (652/54,545; 1%) started NIV after many long-lasting severe exacerbations. The four clusters differed in age, sex, comorbidities, pre-NIV investigations, and prescriber/location of NIV initiation. Mortality differed significantly between clusters: highest in Cluster 4 and lowest in Cluster 1. Interpretation The significant heterogeneity in clinical initiation of NIV probably reflects the current lack of strong evidence and guideline recommendations. Knowledge about the characteristics and outcomes in different clusters should be used to address inequities and facilitate more consistent and personalised use domiciliary NIV in COPD.

Abstract
Background: Microbial culture-independent sequencing techniques have advanced our understanding of host-microbiome interactions in health and disease. The purpose of this study was to explore the dysbiosis of airway microbiota in patients with moderate or severe chronic obstructive pulmonary disease (COPD) and compare them with healthy controls. Methods: The COPD patients were investigated for disease severity based on airflow limitations and divided into moderate (50%≤FEV1<80% predicted) and severe groups (FEV1<50% predicted). Spontaneous sputum samples were collected and, the V3-V4 regions of the 16S rRNA coding gene were sequenced to examine the microbiome profile of COPD and healthy participants. Results: A total of 45 sputum samples were collected from 17 severe COPD, 12 moderate COPD cases, and 16 healthy volunteers. The bacterial alpha diversity (Shannon and Simpson's index) significantly decreased in the moderate and severe COPD groups, compared to healthy samples. A significantly higher proportion of Firmicutes and Actinobacteria were present in moderate COPD, and Proteobacteria numbers were comparatively increased in severe COPD. In healthy samples, Bacteroidetes and Fusobacteria were more abundant in comparison to both the COPD groups. Among the most commonly detected 20 bacterial genera, Streptococcus was predominant among the COPD sputum samples, whereas Prevotella was the top genus in healthy controls. Linear discriminant analysis (LDA>2) revealed that marker genera like Streptococcus and Rothia were abundant in moderate COPD. For severe COPD, the genera Pseudomonasand Leptotrichia were most prevalent, whereas Fusobacterium and Prevotella were dominant in the healthy group. Conclusions: Our findings suggest a significant dysbiosis of the respiratory microbiome in COPD patients. The decreased microbial diversity may influence the host immune response and provide microbiological biomarkers for the diagnosis and monitoring of COPD.

Abstract
COPD is a common, preventable and usually progressive disease associated with an enhanced chronic inflammatory response in the airways and lung, generally caused by exposure to noxious particles and gases. It is a treatable disease characterised by persistent respiratory symptoms and airflow limitation due to abnormalities in the airways and/or alveoli. COPD is currently the third leading cause of death worldwide, representing a serious public health problem and a high social and economic burden. Despite significant advances, effective clinical treatments have not yet been achieved. In this scenario, cell-based therapies have emerged as potentially promising therapeutic approaches. However, there are only a few published studies of cell-based therapies in human patients with COPD and a small number of ongoing clinical trials registered on clinicaltrials.gov Despite the advances and interesting results, numerous doubts and questions remain about efficacy, mechanisms of action, culture conditions, doses, timing, route of administration and conditions related to homing and engraftment of the infused cells. This article presents the state of the art of cell-based therapy in COPD. Clinical trials that have already been completed and with published results are discussed in detail. We also discuss the questions that remain unanswered about cell-based regenerative and translational medicine for COPD.

Abstract
AIMS To determine the lived experiences of people with COPD who isolated at home during the coronavirus disease 2019 (COVID-19) pandemic, and explore how these experiences affected health and patient-reported outcomes. METHODS Keyword searches were performed in five bibliographic databases. Critical interpretative synthesis (CIS) methods were used to interrogate and understand patterns across studies. RESULTS 23 studies were identified; three employed qualitative methods and 20 quantitative methods. Application of CIS methods highlighted a core synthetic concept that appeared to underpin experiences and outcomes, that of a heightened perception of risk. Using the Risk Perception Model as a framework, we found that cognitive factors such as knowledge of underlying health status and the transmissibility of COVID-19; experiential factors including previous episodes of breathlessness and hospitalisation; and sociocultural factors such as access to trusted sources of information, influenced perceptions of risk. In turn, this influenced behaviour, which translated to outcomes such as reduced hospitalisations, deconditioning and social isolation as people avoided "high-risk" situations and settings. CONCLUSIONS Patients with COPD who isolated at home during the COVID-19 pandemic had a heightened perception of risk which was influenced by cognitive, experiential and sociocultural factors. The consequences of this were varied and included both positive (reduced exacerbations and hospitalisations) and negative (social isolation, deconditioning, diminished capacity for self-care) outcomes. Understanding risk and the impacts it can have could help clinicians to support people with COPD return to their pre-pandemic way of living and enable better communication of ongoing risk from respiratory viral illness.

Abstract
Chronic obstructive pulmonary disease (COPD) is a common lung disease. There is a limited amount of nationwide data on COPD patients in Poland. This study aimed to characterize patients hospitalized with COPD in Poland in 2019 as well as to identify factors associated with the risk of in-hospital death and prolonged hospitalization among patients with COPD. This study is a retrospective database analysis. Data on patients hospitalized with COPD in Poland were obtained from the Nationwide General Hospital Morbidity Dataset. Data on all adults aged ≥40 years with a diagnosis of COPD from a physician (J44 code) were included in the analysis. Data were analyzed separately for patients hospitalized due to COPD (primary diagnosis) and patients with COPD as a comorbidity (secondary diagnosis). Completed medical records were available for 101,471 patients hospitalized with COPD (36.9% were females). Of those, 32% were hospitalized due to COPD. The mean age was 71.4 ± 9.7 years. The mean duration of hospitalization was 9.4 ± 11.4 days (median 7 days). Most of the COPD patients (89.3%) had at least one comorbidity. The in-hospital mortality rate was 6.8%. Older age, presence of cardiovascular diseases, and diseases of the genitourinary system (p < 0.05) were the most important factors associated with the risk of in-hospital death among patients hospitalized due to COPD.

Int J Chron Obstruct Pulmon Dis 2023; 18:1815-1825. [PMID: 37636901 PMCID: PMC10454752 DOI: 10.2147/copd.s400707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 07/24/2023] [Indexed: 08/29/2023] Open
Abstract
Purpose For patients with chronic obstructive pulmonary disease (COPD) who remain symptomatic despite maintenance treatment, clinical management guidelines recommend a stepwise escalation from monotherapy to dual therapy, and from dual therapy to triple therapy. However, in clinical practice, patients are often escalated directly from monotherapy to triple therapy based on disease severity. This study evaluated the cost-effectiveness of once-daily, single-inhaler fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI) triple therapy compared with long-acting muscarinic antagonist monotherapy with once-daily tiotropium (TIO) in patients with symptomatic moderate-to-very severe COPD, from a UK National Health Service perspective. Patients and Methods The validated GALAXY-COPD disease progression model was populated with patient baseline characteristics and treatment effect data from the 12-week GSK Study 207626 comparing FF/UMEC/VI with TIO in patients with moderate-to-very severe COPD. UK unit costs and drug costs (British Pound, 2021) were applied to healthcare resource utilization and treatments. The base case analysis was conducted over a lifetime horizon, and costs and health outcomes (except for life years [LYs]) were discounted at 3.5% per year. Model outputs included exacerbation rates, healthcare costs, LYs, quality-adjusted LYs (QALYs), and incremental cost-effectiveness ratios. Results Overall, treatment with FF/UMEC/VI resulted in increased clinical benefit (reduction in total exacerbations and increased overall survival and QALYs), coupled with cost savings (derived from lower maintenance and exacerbation healthcare costs) compared with TIO monotherapy. In the base case analysis, FF/UMEC/VI provided an additional 0.393 LYs (95% range: 0.176, 0.655) and 0.443 QALYs (0.246, 0.648), at a cost saving of £880 (£54, £1608) versus TIO. FF/UMEC/VI remained the cost-effective (dominant) treatment option across sensitivity and scenario analyses. Conclusion FF/UMEC/VI offers greater clinical benefits and is a cost-effective treatment option compared with TIO for the treatment of adult patients with COPD with persistent symptoms and/or who are at risk of exacerbation in the UK.

Abstract
Background Pulmonary rehabilitation (PR) is an effective treatment for patients with chronic obstructive pulmonary disease (COPD). However, referral, uptake, and adherence remain low. Objective To determine effectiveness of interventions to increase patient referral, uptake, and adherence to PR programs for patients with COPD. Methods Randomized controlled trials (RCTs), non-randomized controlled trials, pre-post studies, and uncontrolled studies were sought from 7 databases and 3 clinical trial registries, to end August 2021. Full articles/conference abstracts were included if a coordinated set of activities was targeted to healthcare professionals (HCPs) caring for COPD patients, adults with COPD or their carers, to increase referral, uptake or adherence to any type of PR program. Two review authors independently screened titles, abstracts and full texts, extracted data and critically appraised studies using standard risk of bias tools. Results From 11,272 records, 30 studies (23 full-text; 7 abstracts) met inclusion criteria: study interventions and designs were varied and generally low quality, targeting patients (n=13), HCPs (n=14) or both (n=3 studies). A CCT of patient held evidence score cards increased referral by 7.3% compared to 1.3% for usual care (p-0.03). A cluster RCT involving COPD nurse home visits with individualized care plans increased uptake to 31% compared to 10% in usual care (p=0.002). For people with anxiety or depression, one RCT of cognitive behavioral therapy alongside PR increased adherence (mean sessions 14.0 (sd 1.7) compared to 12.4 (sd 2.6)). Conclusion Although a small number of studies, the weight of evidence suggested that interventions incorporating partnership working between patients and HCPs appeared to increase referral, uptake, and adherence with greater effectiveness than those targeting single populations. Increasing knowledge and empowering HCPs and patients may be important strategies. Concerns about study design and risk of bias suggest clear need for well-designed trials of interventions to report full pathway outcomes.

Abstract
INTRODUCTION The prevalence of chronic obstructive pulmonary disease (COPD) has been on the rise, with acute exacerbation of COPD associated with the highest burden and multiple pulmonary and systemic consequences. People with COPD have been found to have an abnormal response of systemic inflammation. To date, although limited, there are studies that suggest negative associations between inflammatory markers and important clinical outcomes such as exercise capacity and muscle force. This protocol aims to systematically review the evidence for (i) the associations between inflammatory markers and lung function, muscle force and exercise capacity and (ii) the influence of other factors (eg, hospitalisation, exercise programme) on the level of inflammatory markers in people with COPD. METHODS AND ANALYSIS Scopus, PubMed, Cochrane, Web of Science and ProQuest will be searched from database inception to February 2023 using PEO search strategy (Population: adults with COPD; Exposure: inflammatory markers; Outcomes: lung function, muscle force and exercise capacity). Four reviewers working in pairs will independently screen articles for eligibility and extract data that fulfilled the inclusion criteria. Depending on the design of the included studies, either Cochrane risk-of-bias version 2 or the Newcastle-Ottawa Scale tools will be used to rate the methodological quality of the included studies. Effect sizes reported in each individual study will be standardised to Cohen's d and a random effects model will be used to calculate the pooled effect size for the association. ETHICS AND DISSEMINATION Ethical approval is unnecessary as this study will only use publicly available data. The findings will be disseminated through publication in peer-reviewed journals and conferences. PROSPERO REGISTRATION NUMBER CRD42022284446.

Abstract
Purpose Digital tools may improve chronic obstructive pulmonary disease (COPD) management, but further evidence of significant, persisting benefits are required. The RECEIVER trial was devised to evaluate the Lenus COPD support service by determining if people with severe COPD would continue to utilize the co-designed patient web application throughout study follow-up and to explore the impact of this digital service on clinical outcomes with its adoption alongside routine care. Patients and Methods The prospective observational cohort hybrid implementation-effectiveness study began in September 2019 and included 83 participants. Recruitment stopped in March 2020 due to COVID-19, but follow-up continued as planned. A contemporary matched control cohort was identified to compare participant clinical outcomes with and minimize biases associated with wider COVID-19 impacts. Utilization was determined by daily COPD assessment test (CAT) completion through the application. Survival metrics and post-index date changes in annual hospitalizations were compared between the RECEIVER and control cohorts. Longitudinal quality of life and symptom burden data and community-managed exacerbation events were also captured through the application. Results High and sustained application utilization was noted across the RECEIVER cohort with a mean follow-up of 78 weeks (64/83 participants completed at least one CAT entry on ≥50% of possible follow-up weeks). Subgroup analysis of participants resident in more socioeconomically deprived postcode areas revealed equivalent utilization. Median time to death or a COPD or respiratory-related admission was higher in the RECEIVER cohort compared to control (335 days vs 155 days). Mean reduction in annual occupied bed days was 8.12 days vs 3.38 days in the control cohort. Quality of life and symptom burden remained stable despite the progressive nature of COPD. Conclusion The sustained utilization of the co-designed patient application and improvements in participant outcomes observed in the RECEIVER trial support scale-up implementation with continued evaluation of this digital service.

Cureus 2023; 15:e41149. [PMID: 37519550 PMCID: PMC10386883 DOI: 10.7759/cureus.41149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Accepted: 06/29/2023] [Indexed: 08/01/2023] Open
Abstract
Chronic obstructive pulmonary disease (COPD) is a significant public health concern in the Indian subcontinent, with high prevalence rates observed in countries like India, Pakistan, Bangladesh, and neighboring nations. This review article critically examines the occupational risks associated with COPD in the region and emphasizes the need for comprehensive preventive strategies. The review begins by providing background on COPD and highlighting its impact on individuals and the economy. It then explores the different occupational hazards that contribute to the development and progression of COPD, including exposure to airborne pollutants and chemicals, occupational dust, and smoking and secondhand smoke in the workplace. The existing occupational health and safety regulations in the Indian subcontinent are assessed, along with an evaluation of their effectiveness in addressing occupational risks for COPD. The review also highlights gaps and challenges in implementing and enforcing these regulations. The impact of COPD on occupational health and the economy is examined, emphasizing the burden it places on affected individuals and their ability to work. The economic implications of COPD-related productivity losses are evaluated, underscoring the importance of addressing occupational risks to improve workforce health and productivity. Prevention and mitigation strategies are explored, including an overview of preventive measures to reduce occupational risks for COPD, the significance of early detection and diagnosis of COPD in the workplace, and the implementation of engineering controls, personal protective equipment, and ventilation systems. The role of education and training programs for workers and employers is also discussed. The review identifies research gaps in the current understanding of occupational risks and COPD in the Indian subcontinent and suggests future research directions to address these gaps. It emphasizes the importance of collaborative efforts between researchers, policymakers, and industry stakeholders to generate evidence, inform policy decisions, and implement effective interventions.

Prediletto I, Giancotti G, Nava S. COPD Exacerbation: Why It Is Important to Avoid ICU Admission. J Clin Med 2023; 12:jcm12103369. [PMID: 37240474 DOI: 10.3390/jcm12103369] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 04/21/2023] [Accepted: 05/03/2023] [Indexed: 05/28/2023] Open
Abstract
Chronic obstructive pulmonary disease (COPD) is one of the major causes of morbidity and mortality worldwide. Hospitalization due to acute exacerbations of COPD (AECOPD) is a relevant health problem both for its impact on disease outcomes and on health system resources. Severe AECOPD causing acute respiratory failure (ARF) often requires admission to an intensive care unit (ICU) with endotracheal intubation and invasive mechanical ventilation. AECOPD also acts as comorbidity in critically ill patients; this condition is associated with poorer prognoses. The prevalence reported in the literature on ICU admission rates ranges from 2 to 19% for AECOPD requiring hospitalization, with an in-hospital mortality rate of 20-40% and a re-hospitalization rate for a new severe event being 18% of the AECOPD cases admitted to ICUs. The prevalence of AECOPD in ICUs is not properly known due to an underestimation of COPD diagnoses and COPD misclassifications in administrative data. Non-invasive ventilation in acute and chronic respiratory failure may prevent AECOPD, reducing ICU admissions and disease mortality, especially when associated with a life-threating episode of hypercapnic ARF. In this review, we report on up to date evidence from the literature, showing how improving the knowledge and management of AECOPD is still a current research issue and clinical need.

Abstract
This study aims to understand healthcare professionals' thoughts and motivations about optimal management and treatment of patients with chronic obstructive pulmonary disease (COPD). We conducted a DELPHI survey through an online questionnaire distributed to 220 panellists from six European countries and a discrete choice experiment to describe the relationship between selected clinical criteria and the initial COPD treatment of choice. One hundred twenty-seven panellists (general practitioners [GPs] and pulmonologists) completed the survey. Despite the familiarity and use (89.8%) of the GOLD classification for initial treatment selection, a frequent use of LAMA/LABA/ICS was noted. In fact, panellists agreed that inhaled corticosteroids (ICS) are over-prescribed in the primary care setting. Our study showed that GPs felt less confident than pulmonologists with ICS withdrawal. This mismatch observed between best practice and behaviour indicates the need to increase awareness and efforts to improve the adherence to guidelines in clinical practice.

Abstract
INTRODUCTION The aim of our work has been to describe the results of the clinical audit carried out in 2021 and to compare the results with 2015 EPOCONSUL audit. METHODS EPOCONSUL 2021 is a cross-sectional audit that evaluated the outpatient care provided to patients with a diagnosis of chronic obstructive pulmonary disease (COPD) in respiratory clinics in Spain with prospective recruitment between April 15, 2021, and January 31, 2022. RESULTS A total of 45 hospitals participated in the 2021 audit and 4.225 clinical records of patients were evaluated. Clinical phenotype according to the Spanish National Guidelines for COPD care (GesEPOC) was reported in 63.1% of the audited patients, and the COPD type assessment for the Global initiative for chronic Obstructive Lung Disease (GOLD) was present in 38.3%. There was an improved compliance with clinical practice guideline (CPG) recommendations in the 2021 audit with respect to the 2015 audit. There was an increase in the proportion of cases with alfa-1-antitrypsin serum level testing available (audit 1: 18.9%; audit 2: 38.7%, p<0.001) and 6-min walk test carried out (audit 1: 24%; audit 2: 45.2%, p<0.001). However, these significant variations adherence to CPG recommendations were not reached for the clinical evaluation and therapeutic intervention category when adjusting for patient and resource variables. CONCLUSIONS The 2021 EPOCONSUL audit showed increased adherence to recommendations although they seem to be related to the availability of resources for care. These results should be taken into account in order to establish improvements in resources to achieve a better quality of care.

Abstract
Introduction Epidemiological studies are urgently needed to assess the prevalence of COPD in the region to determine the baseline, against which the future trends in the risk factor levels can be assessed and preventive strategies be planned to promote health among the population. Therefore, this study was undertaken to assess the awareness of COPD and its risk factors in Saudi Arabia. Materials and Methods The cross-sectional study was conducted among the general adult population aged 18 years and above living in the Aseer region. A minimum sample of 385 was targeted, using the Raosoft sample size calculator. An online questionnaire was prepared in both English and Arabic language using Google forms and distributed among participants through social media. Results It was observed that less than one-third (116, 30.12%) of the study population had ever heard about COPD. Nearly one-third spent time with smokers. Among all, 223 (57.3%) respondents had never heard and 46 (11.9%) respondents did not know anything about COPD. The majority correctly knew that the lungs are the primary organ affected by COPD (92, 79.3%). Age, sex, marital status, income, and occupation showed a significant association with COPD awareness. Nearly 41.4% knew that COPD progresses exclusively with age, COPD is more expensive for society than lung cancer (49.0%), cigarette smoking affects COPD (34.5%), COPD is fully recoverable with short-term antibiotics (35.0%), COPD lasts more than 18 months (48.1%), COPD can worsen with smoke exposure (37.4%), lead to disability (46.7%) and quitting smoking has an important role in preventing COPD (34.0%). Conclusion The awareness regarding the disease was low among the respondents. Only one-third correctly knew that quitting smoking has an important role in preventing COPD. This study projects an urgent need of improving awareness of COPD and its risk factors in the general population.

Abstract
OBJECTIVE This study aimed to assess the comorbidity profile, use of health care resources and medical costs of patients with chronic obstructive pulmonary disease (COPD) treated at the hospital level in Spain. METHODS Admission records of patients with COPD and at least two admissions registered between January 2016 and December 2020 were obtained from a Spanish hospital discharge database and analyzed in a retrospective multicenter study. RESULTS 95,140 patients met the inclusion criteria; 69.1% were males with a median age of 75 years. Mean Charlson comorbidity index (CCI) was 1.9 in the index admission, increasing to 2.1 during the follow-up period. An acute exacerbation of COPD was registered in 93.6% of patients in the index admission; other secondary diagnoses included respiratory failure (56.8%), essential hypertension (36.9%), hypercholesterolemia (26.7%) and diabetes (26.3%). The age-adjusted incidence rate of COPD was 22.6 per 10,000 persons over the study period, decreasing significantly in the year 2020. Mortality rate was 4.1% for COPD patients, increasing to 6.6% in the year 2020. The year 2020, 191 patients registered a COVID-19 infection, with a mortality rate of 23.0%. Length of hospital stay, and intensive care unit (ICU) stay increased in the follow-up period versus the index admission, similar to admission costs. Mean admission cost was €3212 in the index admission, with cost increases being associated with age, length of stay, ICU stay and CCI. CONCLUSIONS Patients' condition worsened significantly over the follow-up period, in terms of comorbidity and dependence on respirator, with an increased mortality rate and higher admission costs.

Abstract
OBJECTIVE To identify the characteristics of people with chronic obstructive pulmonary disease (COPD) who require hospitalisation for exacerbations. METHODS People with COPD were recruited either during hospitalisation or from out-patient respiratory medicine clinics. Hospital admissions were tracked throughout the 5-months recruitment period. For participants who were admitted, hospital readmissions were tracked for at least 30 days following discharge. Participants were grouped as either needing; (i) no hospital admission during the study period (no admission; ø-A), (ii) one or more hospital admissions during the study period but no readmission within 30 days of discharge (no rapid readmission; ø-RR) or (iii) one or more hospital admissions with a readmission within 30 days of discharge (rapid readmission; RR). RESULTS Compared with the ø-A group (n=211), factors that independently increased the risk of ø-RR (n=146) and/or RR (n=57) group membership were being aged >60 years, identifying as an Indigenous person (relative risk ratio, 95% confidence interval 7.8 [1.8 to 34.0]) and the use of a support person or community service for activities of daily living (1.5 [1.0 to 2.4]. A body mass index ≥25 kg/m2 was protective. CONCLUSIONS Variables recorded at the bedside or in clinic provided information on hospitalisation risk.

Abstract
The negative impact of smoking on the lung is well documented. Cigarette smoke is the cause of 90% of cases of chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema. COPD is a progressive and debilitating condition with morbidity and mortality rates similar to myocardial infarction (MI) and stroke. Despite the widely recognised risks, millions of people continue to smoke, in some cases even after receiving a diagnosis of COPD and despite knowing that the habit will accelerate disease progression. While there is no doubt that smoking cessation is the most important health intervention for all cigarette smokers, it can be challenging. Nicotine addiction, social norms and culture, and the length of time it can take smokers to feel the adverse consequences of the habit all contribute to the high cessation failure rate. However, increasing clinical and epidemiological evidence indicates that for those who are unwilling or cannot stop smoking, harm reduction strategies can help reduce exposure to the harmful chemicals and carcinogens released during tobacco combustion. Electronic devices heat processed tobacco without combusting it to deliver an aerosol containing fewer toxic products or harmful and potentially harmful constituents (HPHC) than cigarette smoke. Clinical evidence to support their use is growing. In Japan, for example, a decrease in hospitalisations due to COPD exacerbation after the introduction of such heat-not-burn (HNB), or tobacco heating systems (THS), has been reported.
In this article, Wolfgang Popp, Döbling Doctor’s Center, Privatklinik Döbling, Vienna, Austria, and Klara Szondy, Semmelweis University, Budapest, Hungary, discuss the impact of cigarette smoke on the lung, and how to support smoking cessation in those willing and able to quit smoking. They also explain when strategies that reduce the harmful effects of smoking may be useful, and outline the latest evidence supporting the use of HNB systems.

Abstract
OBJECTIVE This work aims to analyze the evolution of COPD-related hospitalizations in Galicia from 1996 to 2018 both as main cause of admission (DUE TO COPD) or when coded in any diagnostic order (WITH COPD), assessing the influence of age, sex, seasonality, and other main causes of the hospitalization. METHODS An analysis was conducted of administrative healthcare database (CMBD) data on index COPD-related hospitalizations in Galicia from 1996 to 2018. Crude, specific, and standardized rates were calculated for the entire sample and according to age and sex groups. RESULTS In the period from 1996 to 2018, there were 310,883 index admissions WITH COPD in Galicia, of which 29.6% were DUE TO COPD. Both WITH COPD and DUE TO COPD admission rates increased, mainly in men. There was a clear seasonality that was especially relevant in the DUE TO COPD group. The mean male-to-female ratio was approximately 4:1 in both groups, although it was lower in the extreme age groups, with no change over time. The mean age at admission increased three years in men during this period; there were no changes among women. The main causes of admission in those not hospitalized DUE TO COPD were heart failure and pneumonia. CONCLUSION The combined evaluation of records of hospital admissions WITH COPD and DUE TO COPD offers additional information for a better understanding of the trends of this disease and allows for establishing hypotheses that explain the results described, providing information for better healthcare planning.

Abstract
Continuous measurement of heart rate variability (HRV) in the short and ultra-short-term using wearable devices allows monitoring of physiological status and prevention of diseases. This study aims to evaluate the agreement of HRV features between a commercial device (Bora Band, Biosency) measuring photoplethysmography (PPG) and reference electrocardiography (ECG) and to assess the validity of ultra-short-term HRV as a surrogate for short-term HRV features. PPG and ECG recordings were acquired from 5 healthy subjects over 18 nights in total. HRV features include time-domain, frequency-domain, nonlinear, and visibility graph features and are extracted from 5 min 30 s and 1 min 30 s duration PPG recordings. The extracted features are compared with reference features of 5 min 30 s duration ECG recordings using repeated-measures correlation, Bland-Altman plots with 95% limits of agreements, Cliff's delta, and an equivalence test. Results showed agreement between PPG recordings and ECG reference recordings for 37 out of 48 HRV features in short-term durations. Sixteen of the forty-eight HRV features were valid and retained very strong correlations, negligible to small bias, with statistical equivalence in the ultra-short recordings (1 min 30 s). The current study concludes that the Bora Band provides valid and reliable measurement of HRV features in short and ultra-short duration recordings.

Abstract
This study aims to systematically isolate different anatomical features of the human pharynx with the goal to investigate their independent influence on airflow dynamics and particle deposition characteristics in a geometrically realistic human airway. Specifically, the effects of the uvula, epiglottis and soft palate on drug particle deposition are studied systematically, by carefully removing each of these anatomical features from reconstructed models based on MRI data and comparing them to a benchmark realistic airway model. Computational Fluid Dynamics using established turbulence models is employed to simulate the transport of mono-dispersed particles (3 µm) in the airway at two flow-rates. The simulations suggest three findings: 1) widening the space between the oral cavity and oropharynx and where the soft palate is situated leads to the most dramatic reduction in drug deposition in the upper airway; 2) exclusion of the uvula and epiglottis: a) affects flow dynamics in the airway; b) alters regional deposition behaviour; c) does not significantly affect the total number of particles deposited in the pharynx; and 3) the space adjacent to the soft palate is a key determinant for aerosol deposition in the extrathoracic region and is related to mechanisms of flow acceleration, diversion and recirculation.

Int J Chron Obstruct Pulmon Dis 2022; 17:1883-1895. [PMID: 36003323 PMCID: PMC9394660 DOI: 10.2147/copd.s372439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 08/02/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose GOLD 2019 proposed a novel treatment decision tool for follow-up based on the predominant trait (exacerbation or dyspnea) of patients, alongside treatment escalation and de-escalation strategies. This study was designed to provide an up-to-date snapshot of patient and disease characteristics, treatment pathways, and healthcare resource use (HRU) in COPD in real life, and comprehensively examine patients considering GOLD 2019 recommendations. Patients and Methods This mixed design, observational, multicenter (14 pulmonology clinics) study included all patients with a documented COPD diagnosis (excluding asthma-COPD overlap [ACO]) for ≥12 months, aged ≥40 years at diagnosis who had a COPD-related hospital visit, spirometry test and blood eosinophil count (BEC) measurement under stable conditions within the 12 months before enrollment between February and December 2020. Data were collected cross-sectionally from patients and retrospectively from hospital medical records. Results This study included 522 patients (GOLD group A: 17.2%, B: 46.4%, C: 3.3%, D: 33.1%), of whom 79.5% were highly symptomatic and 36.2% had high risk of exacerbation. Exacerbations (n = 832; 46.6% moderate, 25.5% severe) were experienced by 57.5% of patients in the previous 12 months. Inter-rater agreement between investigators and patients regarding the reason for visit was low (κ coefficient: 0.338, p = 0.001). Inhaled treatment was modified in 88 patients at index, mainly due to symptomatic state (31.8%) and exacerbations (27.3%); treatment was escalated (57.9%, mainly switched to LABA+LAMA+ICS), inhaler device and/or active ingredient was changed (36.4%) or treatment was de-escalated (5.7%). 27% had ≥1 hospital overnight stay over 12 months. Emergency department visits and days with limitation of daily activities were higher in group D (p < 0.001). Conclusion Despite being on-treatment, many patients with COPD experience persistent symptoms and exacerbations requiring hospital-related HRU. A treatable trait approach and holistic disease management may improve outcomes by deciding the right treatment for the right patient at the right time.

Abstract
After hospitalization due to acute COPD exacerbations, patient-manageable behaviors influence rehospitalization frequency. This study's aim was to develop a hospital-ward-initiated Behaviour-Change-Wheel (BCW)-based intervention targeting patients' key health behaviors, with the aim to increase quality of life and reduce rehospitalization frequency. Intervention development was performed by University Hospital Zurich working groups and followed the three BCW stages for each of the three key literature-identified problems: insufficient exacerbation management, lack of physical activity and ongoing smoking. In stage one, by analyzing published evidence - including but not limited to patients' perspective - and health professionals' perspectives regarding these problems, we identified six target behaviors. In stage two, we identified six corresponding intervention functions. As our policy category, we chose developing guidelines and service provision. For stage three, we defined eighteen basic intervention packages using 46 Behaviour Change Techniques in our basic intervention. The delivery modes will be face-to-face and telephone contact. In the inpatient setting, this behavioral intervention will be delivered by a multi-professional team. For at least 3 months following discharge, an advanced nursing practice team will continue and coordinate the necessary care package via telephone. The intervention is embedded in a broader self-management intervention complemented by integrated care components. The BCW is a promising foundation upon which to develop our COPD intervention. In future, the interaction between the therapeutic care team-patient relationships and the delivery of the behavioral intervention will also be evaluated.

Abstract
BACKGROUND AND OBJECTIVE Chronic obstructive pulmonary disease (COPD) incidence, prevalence, mortality and socioeconomic burden are considerable and vary across countries. The aim of the present study was to update the analysis of COPD mortality worldwide using data from the World Health Organization (WHO) up to 2019. METHODS We obtained COPD mortality and population data for 22 European countries and the European Union (EU) as a whole, 10 American countries and six other countries from the WHO mortality database. We calculated age-standardized mortality rates in both sexes and examined trends by country with joinpoint analysis between 1994 and 2019. RESULTS Between 2005-2007 and 2015-2017, overall COPD mortality decreased in EU men (-16.3%) but increased in women (12.7%) to reach rates of 14.0/100,000 in men and of 6.4/100,000 in women. In the United States, mortality declined in men to 21.3/100,000 but rose in women to 18.3/100,000. Mortality declined in most Latin American countries and all Asian countries, while an increase in Australian women was observed. CONCLUSION A steady decrease in COPD mortality was observed in most of countries for men, whilst a different trend was observed in women in several countries. These trends are largely explained by changes in smoking habits, with an additional contribution of air pollution and occupational exposures. Despite past and ongoing tobacco control initiatives, this condition still remains a leading cause of death, in particular in countries with lower socio-demographic indices.

Abstract
BACKGROUND Chronic obstructive pulmonary disease is a progressive disorder with significant physical, psychological, and social consequences and adversely affects the persons' quality of life (QOL). OBJECTIVES This study aimed to determine the health literacy (HL) and QOL of persons with COPD and some of the contributing factors. METHODS A cross-sectional study was conducted from May to December 2019 on 270 persons with COPD referring to Shahid-Beheshti Hospital of Kashan, Iran. Data were collected using a demographic questionnaire, the 33-item Health Literacy Questionnaire of the Urban Population of Iran (with a total score ranging from 33 to 165, higher score indicates higher HL) and the 50-item St. George's Respiratory Questionnaire for assessing the QOL (with a total score ranging from zero to 100, greater score means lower QOL). Descriptive statistics, Pearson and Spearman correlation coefficient, Chi-square test, t-test, analysis of variance, and linear regression analysis were used to analyze the data. RESULTS The mean age and the mean duration of COPD were 59.48±13.31 and 3.85±3.47 years, respectively. The mean HL score and the mean QOL were 81.44±23.89 and 57.41±10.70, respectively. A significant correlation was found between HL and QOL (r=-0.21, p<0.001). CONCLUSION Participants had moderate levels of HL and QOL. There was a significant correlation between HL and QOL. Health care providers are recommended to take effective steps to improve the HL of persons with COPD by developing comprehensive educational programs for them.

Abstract
Objective: To analyze all chronic obstructive pulmonary disease (COPD) drugs-related articles that were indexed in the Web of Science Core Collection (WOSCC) database until August 28, 2021 using bibliometric analysis, in order to provide a reliable reference for the treatment of COPD. Methods: A comprehensive search was conducted to analyze all COPD drugs-related articles using WOSCC database from inception to August 28, 2021. Abstracts and potentially eligible articles, which were retrieved during literature search, were screened by two reviewers. Besides, the CiteSpace (5.8.R1) software was utilized to analyze the overall structure of the network, the network clusters, the links between clusters, the key nodes or pivot points, and the pathways. Results: A total of 2552 COPD-drugs related articles were retrieved. From the perspective of categorization of published articles based on country, the United States is the country with the largest number of published articles and completed clinical trials, highlighting the important role of this country in the treatment of COPD. However, in terms of the proportion of ongoing clinical trials, China has the highest proportion, suggesting that China will play a more pivotal role in the medication of COPD in the future. From the perspective of cooperation among countries, the cooperation among European countries was closer than that among Asian countries. In the recent three decades, the top 20 institutions, with a particular concentration on the treatment of COPD, were from North America and Europe. The co-citation analysis showed that, among 2,552 articles, 53154 citations were recorded, and the co-citation network indicated that 24 clusters could be achieved. Conclusion: The administration of bronchodilators and pulmonary drug delivery systems, as well as consideration of elderly COPD patients remained the hotspots, while triple therapy and comorbidity of COPD, as well as the prevention and treatment of elderly COPD patients had been frontiers in recent years.

Abstract
Alveolar macrophages (AMs) are functionally important innate cells involved in lung homeostasis and immunity and whose diversity in health and disease is a subject of intense investigations. Yet, it remains unclear to what extent conditions like smoking or chronic obstructive pulmonary disease (COPD) trigger changes in the AM compartment. Here, we aimed to explore heterogeneity of human AMs isolated from healthy nonsmokers, smokers without COPD, and smokers with COPD by analyzing BAL fluid cells by flow cytometry and bulk and single-cell RNA sequencing. We found that subpopulations of BAL fluid CD206+ macrophages could be distinguished based on their degree of autofluorescence in each subject analyzed. CD206+ autofluorescenthigh AMs were identified as classical, self-proliferative AM, whereas autofluorescentlow AMs were expressing both monocyte and classical AM-related genes, supportive of a monocytic origin. Of note, monocyte-derived autofluorescentlow AMs exhibited a functionally distinct immunoregulatory profile, including the ability to secrete the immunosuppressive cytokine IL-10. Interestingly, single-cell RNA-sequencing analyses showed that transcriptionally distinct clusters of classical and monocyte-derived AM were uniquely enriched in smokers with and without COPD as compared with healthy nonsmokers. Of note, such smoking-associated clusters exhibited gene signatures enriched in detoxification, oxidative stress, and proinflammatory responses. Our study independently confirms previous reports supporting that monocyte-derived macrophages coexist with classical AM in the airways of healthy subjects and patients with COPD and identifies smoking-associated changes in the AM compartment that may favor COPD initiation or progression.

Abstract
Chronic obstructive pulmonary disease (COPD) and pneumonia are lethal pulmonary illnesses with equivocal nature of abnormal pulmonic acoustics. Using lung sound signals, the classification of pulmonary abnormalities is a difficult task. A standalone system was conceived for screening COPD and Pneumonia patients through signal processing and machine learning methodologies. The proposed system will assist practitioners and pulmonologists in the accurate classification of disease. In this research work, ICBHI's and self-collected lung sound (LS) databases are used to investigate COPD and pneumonia patient. In this scheme, empirical mode decomposition (EMD), discrete wavelet transform (DWT), and analysis of variance (ANOVA) techniques are employed for segmentation, noise elimination, and feature selection, respectively. To overcome the inherent limitation of ICBHI's LS database, the adaptive synthetic (ADASYN) sampling technique is used to eradicate class imbalance. Lung sound features are used to train fine Gaussian support vector machine (FG-SVM) for classification of COPD, pneumonia, and heathy healthy subjects. This machine learning scheme is implemented on low cost and portable Raspberry pi 3 model B+ (Cortex-A53 (ARMv8) 64-bit SoC @ 1.4 GHz through hardware-supported language. Resultant hardware is capable of screening COPD and pneumonia patients accurately and assist health professionals.

Abstract
There are currently no good indicators that can be used to predict the medical expenses of chronic obstructive pulmonary disease (COPD). This was a retrospective study that focused on the correlation between the age, dyspnoea, and airflow obstruction (ADO) index and the Charlson comorbidity index (CCI) on the medical burden in COPD patients, specifically, those of patients with complete ADO index and CCI data in our hospital from January 2015 to December 2016. Of the 396 patients with COPD who met the inclusion criteria, 382 (96.5%) were male, with an average age of 71.3 ± 8.4 years. Healthcare resource utilisation was positively correlated with the ADO index. A significant association was found between the ADO index and CCI of COPD patients (p < 0.001). In-hospitalization expenses were positively correlated with the CCI (p < 0.001). Under the same CCI, the higher the ADO score, the higher the hospitalisation expenses. The ADO quartiles were positively correlated with the number of hospitalisations (p < 0.001), hospitalisation days (p < 0.001), hospitalisation expenses (p = 0.03), and total medical expenses (p = 0.037). Findings from this study show that the ADO index can predict the medical burden of COPD.
