Abstract
Purpose Tobacco smoking is the major risk factor for COPD, and it is common for other risk factors in never-smokers to be overlooked. We examined the prevalence of COPD among never-smokers in Australia and identified associated risk factors. Methods We used data from the Australia Burden of Obstructive Lung Disease (BOLD) study, a cross-section of people aged ≥40 years from six sites. Participants completed interviews and post-bronchodilator spirometry. COPD was primarily defined as an FEV1/FVC ratio <0.70 and secondarily as the ratio less than the lower limit of normal (LLN). Results The prevalence of COPD in the 1656 never-smokers who completed the study was 10.5% (95% CI: 9.1-12.1%) [ratio Conclusion COPD was prevalent in this population of never-smokers aged 40 years and over. This finding highlights the significance of risk factors other than smoking in the development of COPD.

BMC Pulm Med 2023; 23:481. [PMID: 38031050 PMCID: PMC10687794 DOI: 10.1186/s12890-023-02771-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Accepted: 11/17/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) commonly have coexisting comorbidities that contribute to higher exacerbation frequency, poorer health status, and increased all-cause mortality; however, there are only a few studies available on the sex discrepancy in the comorbidity distribution and outcomes among COPD patients, and there is limited information about the discrepancy in all-cause mortality between men and women. METHODS Based on data from the U.S. National Health and Nutrition Examination Survey conducted between 2007 and 2012, we compared participants aged 40-79 years with spirometry-defined COPD to compare the prevalence of comorbidities between men and women. The survival of the subjects was documented, and the sex discrepancy was determined using Kaplan-Meier analysis. Comorbidities and all-cause mortality were analyzed by using a Cox proportional hazards model to determine their strength of association in different sex groups. RESULTS Compared to men, women had a significantly higher prevalence of asthma (OR 1.93, 95% CI 1.46 to 2.57, p < 0.001) and arthritis (OR 1.77, 95% CI 1.39 to 2.24, p < 0.001). Women had a significantly lower prevalence of coronary heart disease (OR 0.48, 95% CI 0.27 to 0.87, p = 0.015) and gout (OR 0.42, 95% CI 0.25 to 0.67, p = 0.001). Kaplan-Meier analysis revealed that compared with that of the female group, the survival rate of the male group was significantly lower (p < 0.001). Among men, the presence of anemia (HR 2.38, [95% CI 1.52-3.73], p < 0.001), gout (HR 1.55, [95% CI 1.04-2.30], p = 0.029) and congestive heart failure comorbidities (HR 1.85, [95% CI 1.12-3.04] p = 0.016) was associated with a higher risk of mortality; among women, the presence of anemia (HR 2.21, [95% CI 1.17-4.20], p = 0.015) and stroke (HR 2.04, [95% CI 1.07-3.88], p = 0.031) comorbidities was associated with a higher risk of mortality after adjusting for age, race/Hispanic status, BMI, smoking status, FEV1% predicted and prevalent comorbidities. CONCLUSIONS COPD-related comorbidities and all-cause mortality were discrepant between men and women, and men had poorer survival than women in the nationally representative data that were analyzed.

Abstract
BACKGROUND & AIMS Sex differences in muscle function and mass, dyspnea, and clinical outcomes have been observed in patients with Chronic Obstructive Pulmonary Disease (COPD) despite a similar level of airflow obstruction. Protein and amino acid metabolism is altered in COPD, however, it remains unclear whether a difference in metabolic signature exists between males and females with COPD that may explain the observed differences in muscle health and clinical outcomes. METHODS In 234 moderate to severe COPD patients (males/females: 113/121) and 182 healthy controls (males/females: 77/105), we assessed, besides presence of comorbidities and clinical features, muscle function by handgrip and leg dynamometry, and body composition by dual-energy x-ray absorptiometry. In the postabsorptive state, a mixture of 18 stable isotopes of amino acids was administered by pulse and arterialized blood was sampled for 2 h. Amino acid concentrations and enrichments were analyzed by LC-MS/MS to calculate whole body (net) protein breakdown (WBnetPB) and whole body production (WBP) rates (μmol/hour) of the amino acids playing a known role in muscle health. Statistics was done by ANCOVA to examine the effects of sex, COPD, and sex-by-COPD interaction with as covariates age and lean mass. Significance was set as p < 0.05. RESULTS Lung function was comparable between males and females with COPD. Being a female and presence of COPD were independently associated with lower appendicular lean mass, muscle strength, and WBnetPB (p < 0.05). Being a male was associated with higher visceral adipose tissue, C-reactive protein (CRP) (p < 0.05), and higher prevalence of heart failure and obstructive sleep apnea. Sex-by-COPD interactions were found indicating lower fat mass (p = 0.0005) and WBPs of phenylalanine (measure of whole body protein turnover) and essential amino acids (p < 0.05), particularly in COPD females. Higher visceral adipose tissue (p = 0.025), CRP (p < 0.0001), and WBP of tau-methylhistidine (p = 0.010) (reflecting enhanced myofibrillar protein breakdown) were observed in COPD males. CONCLUSIONS Presence of sex specific changes in protein and amino acid metabolism and cardiometabolic health in COPD need to be considered when designing treatment regimens to restore muscle health in males and females with COPD.

Abstract
Objective This study aimed to describe the current situation of knowledge, attitude, and practice (KAP) of chronic obstructive pulmonary disease (COPD) prevention among a high-risk population for COPD. Methods A cross-sectional survey was conducted. A total of 241 participants at risk of COPD were selected who visited the respiratory outpatient department of a Class A tertiary hospital in Chongqing, China from January to December 2021. A self-developed COPD prevention KAP assessment was used for evaluation which included knowledge (21 items), attitude (9 items), and practice (9 items) three dimension, 39 items. Results The average overall KAP score was 68.29 ± 12.91, with scores for the knowledge, attitude, and practice dimension was 68.75 ± 18.07, 71.13 ± 15.09 and 65.00 ± 20.93, respectively. Among the people at risk of COPD, 76.8% experienced a moderate level of KAP toward COPD prevention, while 22.0% were at a poor level. Significant differences in the KAP scores were based on gender, educational level, occupation, type of medical insurance, smoking, and passive smoking status (P < 0.05). The male COPD high-risk group has better KAP toward COPD prevention than the female group (P < 0.05). The knowledge and attitude of COPD prevention present worse in people with a high risk of COPD aged 70 or above, primary school and below educational level, and farmers (P < 0.05). Smoking and passive smoking groups have higher recognition of the knowledge but the lower practice of COPD prevention (P < 0.05). Conclusion The participants with a high risk of COPD had a moderate level of KAP for COPD prevention, in which the understanding and action on vaccination and lung function test was weak, but an active attitude for health. It is necessary to implement tailored health education interventions to their characteristics to reduce the incidence and development of COPD.

Abstract
BACKGROUND Comorbidity burden is commonly measured among hospitalized adults, yet the U.S. national norms for 2 commonly used comorbidity indexes have not yet been reported. Thus, this study reports U.S. national norms for both Charlson Comorbidity Index (CCI) and the Elixhauser Comorbidity Index (ECI) among hospitalized adults based on age, biological sex, and race. METHODS A retrospective observational cohort study using data from the Agency of Healthcare Research and Quality U.S. National Inpatient Sample database for 2017. Patient data were extracted from 7 159 694 inpatient adults, and analyses were focused on individuals older than 45 years, yielding 4 370 225 patients. International Classification of Diseases, 10th Edition, diagnostic codes were used to calculate CCI and ECI scores. These scores were then weighted for the U.S. national population. RESULTS The weighted mean CCI was 1.22 (95% confidence interval [CI]: 1.22, 1.22), and the weighted mean ECI was 2.76 (95% CI: 2.76, 2.76). Both indexes had increasing average scores with increasing age, independent of sex and race (all p values < .001). CONCLUSION For the first time, U.S. national norms for the CCI and ECI are reported for adult inpatients. The norms can serve as a reference tool for determining if clinical and research populations have greater or lesser comorbidity burden than typical hospitalized adults in the United States for their age, sex, and race.

Abstract
BACKGROUND Maintenance and reliever therapy (MART) with inhaled corticosteroid (ICS)/formoterol effectively reduces exacerbations in asthma. We aimed to investigate its efficacy compared with fixed-dose fluticasone/salmeterol in chronic obstructive pulmonary disease (COPD). METHODS Patients with COPD and ≥1 exacerbation in the previous 2 years were randomly assigned to open-label MART (Spiromax budesonide/formoterol 160/4.5 µg 2 inhalations twice daily+1 prn) or fixed-dose therapy (Diskus fluticasone propionate/salmeterol combination (FSC) 500/50 µg 1 inhalation twice daily+salbutamol 100 µg prn) for 1 year. The primary outcome was rate of moderate/severe exacerbations, defined by treatment with oral prednisolone and/or antibiotics. RESULTS In total, 195 patients were randomised (MART Bud/Form n=103; fixed-dose FSC n=92). No significant difference was seen between MART and FSC therapy in exacerbation rates (1.32 vs 1.32 /year, respectively, rate ratio 1.05 (95% CI 0.79 to 1.39); p=0.741). No differences in lung function parameters or health status were observed. Total ICS dose was significantly lower with MART than FSC therapy (budesonide-equivalent 928 µg/day vs 1747 µg/day, respectively, p<0.05). Similar proportions of patients reported adverse events (MART Bud/Form: 73% vs fixed-dose FSC: 68%, p=0.408) and pneumonias (MART: 5% vs FSC: 1%, p=0.216). CONCLUSIONS This first study of MART in COPD found that budesonide/formoterol MART might be similarly effective to fluticasone/salmeterol fixed-dose therapy in moderate to severe patients with COPD, at a lower daily ICS dosage. Further evidence is needed about long-term safety.

Abstract
Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are the most devastating events in the course of the disease. Our aim was to investigate the value of early warning scoring systems: National Early Warning Score (NEWS) and Modified Early Warning Score (MEWS) in AECOPD. This is a prospective observational study of patients with AECOPD who were admitted at hospital. The NEWS and MEWS scores were registered at admission (NEWS-d1, MEWS-d1) and on the second day (NEWS-d2, MEWS-d2). A nasopharyngeal and sputum sample was taken for culture. Follow-up was done at 3 and 6 months after hospitalization. Any possible correlations between NEWS and MEWS and other parameters of COPD were explored. A cohort of 64 patients were included. In-hospital mortality was 4.7% while total mortality at 6 months was 26%. We did not find any significant correlation between in-hospital mortality and any of the scores but we could show a higher mortality and more frequent AECOPD at 6 months of follow-up for those with higher NEWS-d2. NEWS-d2 was associated with higher pCO2 at presentation and a more frequent use of NIV. Higher NEWS-d1 and NEWS-d2 were predictive of a longer hospital stay. The presence of pathogens in the nasopharyngeal sample was related with a higher reduction of both scores on the second day. We therefore support the superiority of NEWS in the evaluation of hospitalized patients with AECOPD. A remaining high NEWS at the second day of hospital stay signals a high risk of hypercapnia and need of NIV but also higher mortality and more frequent exacerbations at 6 months after AECOPD.

Abstract
Background Patients with chronic obstructive pulmonary disease (COPD) and no exacerbations may need less maintenance treatment and follow-up. The aim was to identify factors associated with a non-exacerbator COPD phenotype. Methods Cross-sectional analysis of 1354 patients from primary and secondary care, with a doctor's diagnosis of COPD. In 2014, data on demographics, exacerbation frequency and symptoms using COPD Assessment Test (CAT) were collected using questionnaires and on spirometry and comorbid conditions by record review. The non-exacerbator phenotype was defined as having reported no exacerbations the previous six months. Multivariable logistic regression with the non-exacerbator phenotype as dependent variable was performed, including stratification and interaction analyses by sex. Results The non-exacerbator phenotype was found in 891 (66%) patients and was independently associated with COPD stage 1 (OR [95% CI] 5.72 [3.30-9.92]), stage 2 (3.42 [2.13-5.51]) and stage 3 (2.38 [1.46-3.88]) compared with stage 4, and with CAT score <10 (3.35 [2.34-4.80]). Chronic bronchitis and underweight were inversely associated with the non-exacerbator phenotype (0.47 [0.28-0.79]) and (0.68 [0.48-0.97]), respectively. The proportion of non-exacerbators was higher among patients with no maintenance treatment or a single bronchodilator. The association of COPD stage 1 compared with stage 4 with the non-exacerbator phenotype was stronger in men (p for interaction 0.048). In women, underweight and obesity were both inversely associated with the non-exacerbator phenotype (p for interaction 0.033 and 0.046 respectively), and in men heart failure was inversely associated with the non-exacerbator phenotype (p for interaction 0.030). Conclusion The non-exacerbator phenotype is common, especially in patients with no maintenance treatment or a single bronchodilator, and is characterized by preserved lung function, low symptom burden, and by absence of chronic bronchitis, underweight and obesity and heart failure. We suggest these patients may need less treatment and follow-up, but that management of comorbid conditions is important to avoid exacerbations.

Abstract
Rationale: Women have worse outcomes than men in several conditions more common in men, including cardiac surgery and burns. Objectives: To describe the relationship between sex balance within each diagnostic group of ICU admissions, defined as the percentage of patients who were women, and hospital mortality of women compared with men with that same diagnosis. Methods: We studied ICU patients in the Australian and New Zealand Intensive Care Society's Adult Patient Database (2011-2020). We performed mixed effects logistic regression for hospital mortality adjusted for sex, illness severity, ICU lead time, admission year, and hospital site. We compared sex balance with the adjusted hospital mortality of women compared with men for each diagnosis using weighted linear regression. Measurements and Main Results: There were 1,450,782 admissions (42.1% women), with no difference in the adjusted hospital mortality of women compared with men overall (odds ratio, 0.99; 99% confidence interval [CI], 0.97 to 1). As the percentage of women within each diagnosis increased, the adjusted mortality of women compared with men with that same diagnosis decreased (regression coefficient, -0.015; 99% CI; -0.020 to -0.011; P < 0.001), and the illness severity of women compared with men at ICU admission decreased (regression coefficient, -0.0026; 99% CI, -0.0035 to -0.0018; P < 0.001). Conclusions: Sex balance in diagnostic groups was inversely associated with both the adjusted mortality and illness severity of women compared with men. In diagnoses with relatively few women, women were more likely than men to die. In diagnoses with fewer men, men were more likely than women to die.

Abstract
INTRODUCTION Only a few studies have examined the effectiveness of tobacco control policies on respiratory conditions, and the results were less consistent. The 2015 Beijing tobacco control policy package incorporating all six components of MPOWER has been implemented since Jun 2015. The present study aimed to evaluate the impact of a comprehensive tobacco control policy package on hospital admissions for chronic obstructive pulmonary disease (COPD) in Beijing, China. AIMS AND METHODS An interrupted time-series study was conducted based on the hospital admission information for about 18 million residents, who were covered by the Beijing Medical Claim Data for Employees from January 2013 to June 2017. The average percentage change of COPD hospital admission rates and reductions in hospital admission numbers were estimated by segmented Poisson regression models. RESULTS There were 54 040 COPD hospital admissions with a crude rate of 67.2 per 100 000 residents during the observational period. After the implementation of the policy package, the hospital admission rates of COPD were reduced by -14.7% (95%CI: -17.8%, -11.5%) immediately. The secular trend was slowed down by -3.0% (95% CI: -5.6%, -0.4%) annually. A total of 5 581 reductions in COPD hospital admissions were estimated during the 25 months post-law period, accounting for 17.5% (95% CI: 12.5%, 22.5%) of overall COPD hospital admissions. More reductions were shown in males and those aged over 65 years old. CONCLUSIONS The results indicated significant protections against hospitalization of COPD after the 2015 Beijing comprehensive tobacco control policy package. The results provide support for public health benefits for respiratory conditions from WHO-recommended tobacco control measures. IMPLICATIONS Only a few studies have examined the effectiveness of tobacco control policies on respiratory conditions, and the results were less consistent. Based on medical records for about 18 million residents, this study showed an association between comprehensive tobacco control policies and significant reductions of hospital admissions for chronic obstructive pulmonary disease. The results provide support for public health benefits for respiratory conditions from WHO-recommended tobacco control measures.

Abstract
The prevalence of chronic obstructive pulmonary disease (COPD) is increasing worldwide, with the fourth highest mortality rate. This study aims to analyze pulmonary function, physical activity, and quality of life (QoL) between genders from the perspective of pulmonary rehabilitation in Korean patients with COPD. This study investigated raw data from the Korea National Health and Nutrition Examination Survey from 2015 to 2019 and included 151 COPD patients (men: 66.55 ± 10.07 years, women: 65.21 ± 11.73) out of 39,759 participants. Pulmonary function, such as forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1), and frequency of physical activities (e.g., physical activity for work and leisure, strengthening exercise, and sitting time a day) and QoL by using EQ-5D-3L, were compared between genders in patients with COPD. Smoking status differed in health-related characteristics between genders (P < .001). In pulmonary function, the FVC (men: 3.48 ± 0.98ℓ, women: 2.53 ± 0.56ℓ, P < .05), FEV1 (men: 2.13 ± 0.93 ℓ, women: 1.88 ± 0.53 ℓ, P < .001), FEV6 (men: 3.16 ± 1.00ℓ, women: 2.46 ± 1.56ℓ, P < .001) and peak expiratory flow (men: 5.61 ± 2.44ℓ/s, women: 4.68 ± 1.53ℓ/s, P < .05) was higher in men, however, predicted FEV1 (men: 66.03% ± 23.13%, women: 79.95% ± 18.45%, P < .05) and predicted FEV1/FVC ratio (men: 59.67% ± 15.02%, women: 74.10% ± 10.49%, P < .001) in women. The frequency of strengthening exercise was higher in men (P < .05). QoL of patients with COPD was not significantly different between genders. To provide correct interventions and pulmonary rehabilitation to patients with COPD, gender differences, including physiological and psychological differences, must be considered.

Abstract
Background Patients with mild chronic obstructive pulmonary disease (COPD) account for more than half of the total COPD population but are often undiagnosed and sparsely studied. This real-world, longitudinal study compared the socioeconomic burden, clinical characteristics and treatment patterns in patients with mild COPD and age- and gender-matched controls. Patients and methods Our population included mild COPD patients (forced expiratory volume in one second ≥80% of predicted value) and reference controls from 52 Swedish primary care centres over 15 years (2000-2014). We linked electronic medical record (EMR) data to Sweden's National Health Registries. The outcomes analyzed were socioeconomic status including annual income from work, presence of comorbidities and the use of medications. Results 844 patients with mild COPD were included in this study and matched with 844 reference controls. Compared with the reference controls, mild COPD patients had a significantly lower annual income from work (mean difference, men: 12,559€ and women: 7143€) and were significantly less likely to be married or employed. The presence of comorbidities, including cardiovascular disease, anxiety and depression (only women) was significantly higher in mild COPD patients. The use of medications, such as proton pump inhibitors, antidepressants, central painkillers and sleep medications, was significantly higher in the mild COPD group. Conclusion Mild COPD presents a considerable socioeconomic and clinical burden compared with reference controls The findings suggest that COPD constitutes a condition that influences health status even in mild disease clearly demanding an increased need for early detection and treatment.

Abstract
In patients with COPD, it has not been comprehensively assessed whether the predictive value of comorbidities for mortality differs between men and women. We therefore aimed to examine sex differences of COPD comorbidities in regard with prognosis by classifying comorbidities into a comorbidome related to extrapulmonary disorders and a pulmorbidome, referring to pulmonary disorders. The study population comprised 1044 women and 1531 men with the diagnosis of COPD from COSYCONET, among them 2175 of GOLD grades 1–4 and 400 at risk. Associations of comorbidities with mortality were studied using Cox regression analysis for men and women separately. During the follow-up (median 3.7 years) 59 women and 159 men died. In men, obesity, hypertension, coronary artery disease, liver cirrhosis, osteoporosis, kidney disease, anaemia and increased heart rate (HR) predict mortality, in women heart failure, hyperuricemia, mental disorders, kidney disease and increased HR (p < 0.05 each). Regarding the pulmorbidome, significant predictors in men were impairment in diffusion capacity and hyperinflation, in women asthma and hyperinflation. Similar results were obtained when repeating the analyses in GOLD 1–4 patients only. Gender differences should be considered in COPD risk assessment for a tailored approach towards the treatment of COPD. Clinical Trial Registration: ClinicalTrials.gov NCT01245933.

Abstract
Chronic obstructive pulmonary disease (COPD) is a debilitating medical condition often accompanied by multiple chronic conditions. COPD is more frequent among older adults and affects both genders. The aim of the current cross-sectional survey was to characterize chronic comorbidities stratified by gender and age among patients with COPD under the care of general practitioners (GP) and pulmonologists, using real-world patient data. A total of 7966 COPD patients (women: 45%) with more than 5 years of the observation period in the practice were examined using 60 different Chronic comorbid conditions (CCC) and Elixhauser measures. More than 9 in 10 patients had at least one, and 51.7% had more than three comorbidities. No gender difference was found in the number of comorbidities. However, men had higher Elixhauser-van Walraven index scores than women, and the types of comorbidities differed by gender. An increasing number of comorbidities was seen with aging but the patients in their 30s and 40s also had a high number of comorbidities. Moreover, GP patients had a higher number and a wider array of documented comorbidities than pulmonology patients did. Psychological comorbidities were common in all patients, but particularly among younger patients. These findings around gender- and age-stratified comorbidities under the care of GPs and pulmonologists have implications for the choice of data provenience for decision-making analysis and treatment selection and success.

Abstract
Purpose People with COPD are at a higher risk of cognitive dysfunction than the general population. However, the additional impact of dementia amongst such patients is not well understood, particularly in those admitted with a COPD exacerbation. We assessed the impact of coexisting dementia on inpatient mortality and length of stay (LOS) in patients admitted to hospital with a COPD exacerbation, using the United States based National Inpatient Sample database. Patients and Methods Patients aged over 40 years and hospitalised with a primary diagnosis of COPD exacerbation from 2011 to 2015 were included. Cases were grouped into patients with and without dementia. Multivariable logistic regression analysis, stratified by age, was used to assess risk of inpatient deaths. Cox regression was carried out to compare death rates and competing risk analysis gave estimates of discharge rates with time to death a competing variable. Results A total of 576,381 patients were included into the analysis, of which 35,372 (6.1%) had co-existent dementia. There were 6413 (1.1%) deaths recorded. The odds of inpatient death were significantly greater in younger patients with dementia (41–64 years) [OR (95% CI) dementia vs without: 1.75 (1.04–2.92), p=0.03]. Cases with dementia also had a higher inpatient mortality rate in the first 4 days [HR (95% CI) dementia vs without: 1.23 (1.08–1.41), p=0.002] and a longer LOS [sub-hazard ratio (95% CI) dementia vs without: 0.93 (0.92–0.94), p<0.001]. Conclusion Dementia as a comorbidity is associated with worse outcomes based on inpatient deaths and LOS in patients admitted with COPD exacerbations.

Abstract
Chronic obstructive pulmonary disease (COPD) is no longer a respiratory disease that predominantly affects men, to the point where the prevalence among women has equaled that of men since 2008, partly due to their increasing exposure to tobacco and to biomass fuels. Indeed, COPD has become the leading cause of death in women in the USA. A higher susceptibility of female to smoking and pollutants could explain this phenomenon. Besides, the clinical presentation appears different among women with more frequent breathlessness, anxiety or depression, lung cancer (especially adenocarcinoma), undernutrition and osteoporosis. Quality of life is also more significantly impaired in women. The theories advanced to explain these differences involve the role of estrogens, smaller bronchi, impaired gas exchange in the lungs and smoking habits. Usual medications (bronchodilators, ICS) demonstrated similar trends for exacerbation prevention and lung function improvement in men and women. There is an urgent need to recognize the increasing burden of COPD in women and therefore to facilitate global improvements in disease management (smoking cessation, pulmonary rehabilitation…) in half of the population. Nevertheless, important limitations to the treatment of women with COPD include greater under-diagnosis than in men, fewer spirometry tests and medical consultations. In conclusion there is an urgent need to recognize the increasing burden of COPD in women and therefore to facilitate globally improvements in disease management in this specific population.

Abstract
The primary barrier to initiating palliative care for advanced COPD patients is the unpredictable course of the disease. We enroll 752 COPD patients into the study and validate the prediction tools for 1-year mortality using the current guidelines for palliative care. We also develop a composite prediction index for 1-year mortality and validate it in another cohort of 342 patients. Using the current prognostic models for recent mortality in palliative care, the best area under the curve (AUC) for predicting mortality is 0.68. Using the Modified Medical Research Council dyspnea score and oxygen saturation to define the combined dyspnea and oxygenation (DO) index, we find that the AUC of the DO index is 0.84 for predicting mortality in the validated cohort. Predictions of 1-year mortality based on the current palliative care guideline for COPD patients are poor. The DO index exhibits better predictive ability than other models in the study.

Abstract
The burden of morbidity among privately insured transgender people is largely unknown. We identified transgender people enrolled in private insurance (using claims from 2001-19) and compared their rates of selected chronic conditions, using the Elixhauser Comorbidity Index, with claims for a matched cisgender cohort. We documented disparities between transgender and cisgender people across most conditions and found that transgender people were at elevated risk for nearly all chronic conditions compared with their cisgender counterparts. We also found that trans masculine and nonbinary people had the highest predicted average number of chronic conditions compared with all other gender groups. Our findings highlight key gender differences in morbidity between and within transgender and cisgender populations, and they underscore the importance of collecting gender identity information in national surveillance efforts to increase understanding of the health disparities among transgender and cisgender populations. In addition, these findings underscore the need for nondiscrimination protections for transgender people in the US.

Latiers F, Vandenabeele M, Poncin W, Reychler G. Prevalence and risk factors of musculoskeletal pain in patients with chronic obstructive pulmonary disease: A systematic review. CLINICAL RESPIRATORY JOURNAL 2021; 15:1286-1301. [PMID: 34459145 DOI: 10.1111/crj.13443] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 08/14/2021] [Accepted: 08/25/2021] [Indexed: 11/26/2022]
Abstract
OBJECTIVES This systematic review aimed to discuss the prevalence and the risk factors of the musculoskeletal pain in chronic obstructive pulmonary disease (COPD). DATA SOURCE AND STUDY SELECTION Four databases were analysed (Scopus, PubMed, Cochrane and EMBASE). We excluded systematic reviews, meta-analyses, conference abstracts and case reports. Two authors independently checked for the eligibility of the relevant articles. The risk of bias was evaluated using the Newcastle Ottawa Quality Assessment Scale and the Joanna Briggs Institute critical appraisal checklist. The selection and evaluation of studies followed the PRISMA guidelines. RESULTS Twenty studies were retrieved, including from 21 to 7952 patients with COPD. The prevalence of pain was highly heterogeneous across studies: 7-89.7%. Pain was mostly reported in the lumbar (7-69%) and cervical spine (11-48.3%) and the chest (44-82.8%). The main risk factors for developing pain were old age, sex (female), level of physical activity (low) and comorbidities. CONCLUSION Pain is a very common symptom in patients with COPD. Despite this, few clinical trials have investigated the pain. It appears to be located primarily in the lumbar, cervical and thoracic regions and facilitated by being a female, a low level of physical activity, comorbidity(ies) and old age.

Access to, use, knowledge, and preferences for information technology and technical equipment among people with chronic obstructive pulmonary disease (COPD) in Sweden. A cross-sectional survey study. BMC Med Inform Decis Mak 2021; 21:185. [PMID: 34112150 PMCID: PMC8191435 DOI: 10.1186/s12911-021-01544-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 05/27/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The use of information technology can make pulmonary rehabilitation interventions in people with chronic obstructive pulmonary disease (COPD) more flexible and thereby has the potential to reach a larger proportion of the population. However, the success of using information technology in pulmonary rehabilitation is dependent on the end-user's competence in information technology and access to the Internet. The aim was to describe the access to, and the use, knowledge, and preferences of information technology and technical equipment among people with COPD. METHODS Telephone interviews were conducted using a standardised questionnaire on information technology and technical devises addressing the household, access to and usage of the Internet, contact with authorities, e-commerce, security, the workplace, digital competence, and disabilities. Questions were also posed regarding participants' views on a future eHealth tool for COPD, appropriate content, and the potential likelihood for them to use an eHealth tool for exercise training. RESULTS In total 137 persons agreed to participate, 17 dropped out resulting in 120 included participants (response rate 88%). The participants (86 women) were aged 51 to 92 years (mean: 72.5), and all severity grades of COPD according to GOLD A-D were represented. Over 90% had access to the Internet. Smartphones were used by 81%, and over 90% used apps. Participants had high knowledge of how to use the Internet, 91% had used the Internet during the last 3 months, 85% almost every day. The most common requests for a future eHealth tool for COPD were evidence-based and trustworthy information on COPD, (including medication, exercise training, inhalation and breathing techniques), communication (chat) with others and with health carers. Access to individually adjusted exercise training, and support, (motivation via prompts, chat rooms, digital information board) was also desired. CONCLUSIONS The present study showed that people with COPD in Sweden have high access and ability to use the Internet and information technology. They are frequent users and most of them take part in the digital society, even to a higher extent than the general population. The results show that the use of an eHealth tool could be a suitable strategy for people with COPD.

Developing a short-term prediction model for asthma exacerbations from Swedish primary care patients' data using machine learning - Based on the ARCTIC study. Respir Med 2021; 185:106483. [PMID: 34077873 DOI: 10.1016/j.rmed.2021.106483] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 05/21/2021] [Accepted: 05/23/2021] [Indexed: 12/23/2022]
Abstract
OBJECTIVE The ability to predict impending asthma exacerbations may allow better utilization of healthcare resources, prevention of hospitalization and improve patient outcomes. We aimed to develop models using machine learning to predict risk of exacerbations. METHODS Data from 29,396 asthma patients was collected from electronic medical records and national registers covering clinical and epidemiological factors (e.g. comorbidities, health care contacts), between 2000 and 2013. Machine-learning classifiers were used to create models to predict exacerbations within the next 15 days. Model selection was done using the mean cross validation score of area under precision-recall curve (AUPRC). RESULTS The most important predictors of exacerbation were comorbidity burden and previous exacerbations. Model validation on test data yielded an AUPRC = 0.007 (95% CI: ± 0.0002), indicating that historic clinical information alone may not be sufficient to predict a near future risk of asthma exacerbation. CONCLUSIONS Supplementation with additional data on environmental triggers, (e.g. weather, pollen count, air quality) and from wearables, might be necessary to improve performance of the short-term predictive model to develop a more clinically useful tool.

Abstract
OBJECTIVE Rheumatoid arthritis (RA) and chronic obstructive pulmonary disease (COPD) are both chronic inflammatory diseases; the prevalence of COPD in RA patients is known to be high. However, the prevalence of both RA and COPD differs according to sex; the relationship between RA and COPD may also vary according to sex. Therefore, we investigated the prevalence of COPD and its association in patients with RA in Korea by sex. METHODS We conducted a nationwide cross-sectional study using data from the Korea National Health and Nutrition Examination Survey. A total of 12 417 men and 15 878 women were included. In this study, RA was defined as physician diagnosed or currently under RA treatment. COPD was defined based on spirometry results, chronic symptoms, and smoking history. Multivariable logistic regression models were employed and we calculated the odds ratios (ORs) and 95% confidence intervals (CIs) for COPD prevalence in patients with RA. RESULTS The prevalence of COPD was 15.5% in men with RA, 3.5% in women with RA, 7.8% in men without RA, and 2.2% in women without RA. After adjustment for potential confounding variables, including smoking status, RA was significantly associated with COPD in men (OR 2.16, 95% CI 1.06-4.40), but not in women (OR 1.58, 95% CI 0.81-3.10). CONCLUSIONS In Korea, the prevalence of COPD was high in patients with RA of both sexes; RA and COPD was significantly likely to be associated in men, but not in women.

Abstract
BACKGROUND Living with chronic obstructive pulmonary disease stage III or IV has a major impact on a person's everyday life. This qualitative study focuses on women with chronic obstructive pulmonary disease stage III or IV. AIM The aim of this study was to describe women's experiences of living with chronic obstructive pulmonary disease stage III or IV. METHOD A purposive sample of fifteen women with chronic obstructive pulmonary disease stage III or IV participated in the study. Data were collected through individual semi-structured interviews that were subjected to qualitative content analysis. FINDINGS One theme was identified, stabilizing an ever-present breathlessness by restoring strength, and three categories are as follows: managing a restricted everyday life as an expert of their illness, being afraid of contracting infections leading to suffocation and suffering and importance of continuous help and support from significant others and digital media. Breathlessness restricted women with chronic obstructive pulmonary disease, living with a body they have to wait for. Managing everyday life was adapted to their limited abilities and energy. This required detailed planning, good knowledge of their breathing and body. Women were afraid of contracting life-threatening infections that caused suffering, especially COVID-19. The fear leads to isolation and digital media was described as an important means of communication. Significant others gave support and help that was practical and emotional. Women with chronic obstructive pulmonary disease experienced lack of continuous help and support from healthcare professionals. CONCLUSION Stabilizing an ever-present breathlessness by restoring strength required women with chronic obstructive pulmonary disease stage III or IV to conduct detailed planning to manage everyday life. Being afraid of contracting infections and the consequences of suffocation had increased since the pandemic COVID-19 outbreak, which led to self-isolation and an inactive everyday life. To get help, support and socialize, women used digital media.

Abstract
Objective: To determine the effects of pulmonary rehabilitation in men and women with a COPD diagnosis in a Colombian clinic.
Method: A longitudinal and descriptive study was conducted with 75 COPD patients who entered a pulmonary rehabilitation program during 2018 and 2019. The population was divided into groups according to gender and some sociodemographic characteristics were assessed, such as spirometry expressed in percentage of the predicted value, body mass index, mMRC dyspnea, and capacity for physical exercise, as well as some physiological variables with the six-minute walk test, anxiety-depression (HADS) and quality of life (SGRQ). A p-value<0.05 was considered statistically significant.
Results: The cigarette packs smoked per year index was higher in men, 34±29.11 (p<0.001), whereas the exposure to firewood smoke was five times higher in women (p=0.037). All the variables related to the capacity for physical exercise improved significantly (p<0.021), with distance covered standing out: 63.26±60.03 vs. 51.53±61.02 in favor of women. mMRC dyspnea was initially higher in women when compared to men, 0.709±0.287, and presented a greater change in women with 1.294±0.415 when compared to men, 0.736±0.880, at the end of pulmonary rehabilitation.
Conclusion: Pulmonary rehabilitation in women shows an increase of 63.26 meters in the distance covered and a 1.294-point reduction in dyspnea; while, for men, these figures were 51.53 meters and 0.736 points, respectively, as well as an improvement in quality of life in men by 11.47 SGRQ points when compared to women: 0.600.

Abstract
BACKGROUND There are few reports on exercise-induced desaturation (EID) as a predictor of mortality in chronic obstructive pulmonary disease (COPD). However, the definitions of EID vary in published reports. The main purpose was to evaluate the association between EID and long-term mortality by applying two criteria of EID. METHODS A total of 507 subjects were selected from the Korean Obstructive Lung Disease cohort. EID was assessed using the 6-min walk test (6MWT) and defined using two different criteria [1]: post-6MWT oxygen saturation (SpO2) of ≤88% (criterion A) and [2] post-6MWT SpO2 < 90% or a decrease of ≥4% compared to baseline (criterion B). RESULTS The prevalence of EID was 5.1% based on criterion A and 13.0% based on criterion B. Regardless of the criteria used, mortality was higher in the EID group than in the non-EID group (A: 50 vs. 11.4%, B: 33.3 vs. 10.4%) during up to 161 months of follow-up. COPD patients without EID survived significantly longer than those with EID (A: 143.5 vs. 92.9, B: 144.8 vs. 115.2 months). Multivariate Cox regression analysis revealed that COPD patients with EID had a 2.4-fold increased risk of death by criterion A (adjusted HR 2.375; 95% CI: 1.217-4.637; P = 0.011). The risk of death increased in COPD patients with EID by criterion B, but the difference was not statistically significant. CONCLUSIONS COPD patients with EID demonstrated significantly higher long-term mortality than those without EID. The EID criterion A has a better predictive value for mortality in COPD.

Abstract
Objective To evaluate the perception of physicians on gender-specific differences in the diagnosis of chronic obstructive pulmonary disease (COPD) using a qualitative and anonymous questionnaire-based survey. Methods The survey was conducted amongst respiratory physicians attending a standalone educational conference (29-30 September 2017) using the SpotMe® App. The 20-item standardized closed questionnaire had pre-coded responses to questions on physician's profile, and perception of COPD diagnosis and existing comorbidities between genders. All the responses were recorded anonymously. Results Of 368 physicians who downloaded the SpotMe® App and had access to the survey, 132 (35.9%) completed the survey. Respondents were predominantly hospital-based (57.3%), aged 30-49 years (54.2%), male (56.5%), and from large cities (59.5%). 68.7% of physicians perceived the prevalence of COPD to be higher in men; over 50% of physicians perceived that women were more prone to the effects of smoking. More than 60% of physicians agreed that women experience more severe symptoms (anxiety and depression) and have reduced quality of life than men. Over 50% of physicians agreed that misdiagnosis/underdiagnosis of COPD in women was an important factor for gender-differences. Conclusion Results from this survey indicate that the understanding of COPD burden in women varies among healthcare professionals.

Abstract
Introduction: A growing body of evidence indicates that prevalence of chronic obstructive pulmonary disease (COPD) has been increasing more rapidly among women compared to men, but the available data on the differences between the sexes in the responses to the various COPD therapies are still scarce.Areas covered: The aim of this narrative review is to provide an overview of current knowledge on sex differences in COPD management.Expert opinion: There is no solid evidence of sex differences in response to usual COPD treatments but there are sex-related differences in management of patients with a clinical diagnosis of COPD. It is difficult to explain the reason for these differences, but most likely they are due to local prescribing habits, rather than solid scientific reasons. However, there are also signals of different sex-related responses, the qualification and quantification of which is difficult with the information currently available. These signals should lead to the inclusion of more women in clinical trials, but also to the design of prospective clinical studies to assess the possible differences linked to sex in COPD treatment responses, whose identification is an important step toward the definition of personalized COPD therapy.

Abstract
An individual's experience of COPD is determined by many factors in addition to the pathological features of chronic bronchitis and emphysema and the symptoms that derive directly from them. Multimorbidity is the norm rather than the exception, so most people with COPD are living with a range of other medical problems which can decrease overall quality of life. COPD is caused by the inhalation of noxious particles or gases, in particular tobacco smoke, but also by early life disadvantage impairing lung development and by occupations where inhaled exposures are common (e.g. industrial, farming and cleaning work). Wealthy people are therefore relatively protected from developing COPD and people who do develop the condition may have reduced resources to cope. COPD is also no longer a condition that predominantly affects men. The prevalence of COPD among women has equalled that of men since 2008 in many high-income countries, due to increased exposure to tobacco, and in low-income countries due to biomass fuels. COPD is one of the leading causes of death in women in the USA, and death rates attributed to COPD in women in some countries are predicted to overtake those of men in the next decade. Many factors contribute to this phenomenon, but in addition to socioeconomic and occupational factors, there is increasing evidence of a higher susceptibility of females to smoking and pollutants. Quality of life is also more significantly impaired in women. Although most medications (bronchodilators and inhaled corticosteroids) used to treat COPD demonstrate similar trends for exacerbation prevention and lung function improvement in men and women, this is an understudied area and clinical trials frequently have a preponderance of males. A better understanding of gender-based predictors of efficacy of all therapeutic interventions is crucial for comprehensive patient care. There is an urgent need to recognize the increasing burden of COPD in women and to facilitate global improvements in disease prevention and management in this specific population. Many individuals with COPD follow a trajectory of both lung function decline and also multimorbidity. Unfavourable lung function trajectories throughout life have implications for later development of other chronic diseases. An enhanced understanding of the temporal associations underlying the development of coexisting diseases is a crucial first step in unravelling potential common disease pathways. Lessons can be learned from exploring disease trajectories of other NCD as well as multimorbidity development. Further research will be essential to explain how early life risk factors commonly influence trajectories of COPD and other diseases, how different diseases develop in relation to each other in a temporal way and how this ultimately leads to different multimorbidity patterns in COPD. This review integrates new knowledge and ideas pertaining to three broad themes (i) the overall burden of disease in COPD, (ii) an unappreciated high burden in women and (iii) the contrast of COPD trajectories and different multimorbidity patterns with trajectories of other NCD. The underlying pathology of COPD is largely irreversible, but many factors noted in the review are potentially amenable to intervention. Health and social care systems need to ensure that effective treatment is accessible to all people with the condition. Preventive strategies and treatments that alter the course of disease are crucial, particularly for patients with COPD as one of many problems.

Abstract
Introduction COPD is a major cause of morbidity and mortality. The prevalence, morbidity and mortality of COPD among females have increased. Previous studies indicate a possible gender bias in the diagnosis and management of COPD. The present study aims to determine if there is gender bias in the management of COPD in Sweden. Methods This was a double-blind, randomised (1:1), controlled, parallel-group, web-based trial using the hypothetical case scenario of a former smoker (40 pack-years and quit smoking 3 years ago) who was male or female. The participants were blind to the randomisation and the purpose of the trial. The case progressively revealed more information with associated questions on how the physician would manage the patient. Study participants chose from a list of tests and treatments at each step of the case scenario. Results In total, 134 physicians were randomised to a male (n=62) or a female (n=72) case. There was no difference in initial diagnosis (61 (98%) male cases and 70 (97%) female cases diagnosed with COPD) and planned diagnostic procedures between the male and female cases. Spirometry was chosen by all the physicians as one of the requested diagnostic tests. The management of the hypothetical COPD case did not differ by sex of the responding physician. Conclusion In Sweden, diagnosis and management of a hypothetical patient with COPD did not differ by the gender of the patient or physician.

Inhaled corticosteroids and the risk of type 2 diabetes among Swedish COPD patients. NPJ Prim Care Respir Med 2020; 30:47. [PMID: 33082331 PMCID: PMC7576803 DOI: 10.1038/s41533-020-00207-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 09/23/2020] [Indexed: 11/08/2022] Open
Abstract
This study reports the association of ICS use and the risk of type 2 diabetes mellitus (T2DM) in Swedish patients with COPD using data from real-world, primary care settings. A total of 7078 patients with COPD were included in this analysis and the 5-year cumulative incidence rate per 100,000 person years was 1506.9. The yearly incidence rate per 100,000 person years ranged from 850 to 1919. Use of ICS especially at a high dose in patients with COPD was related to an increased risk of T2DM.

Amerindian Ancestry Influences Genetic Susceptibility to Chronic Obstructive Pulmonary Disease. J Pers Med 2020; 10:jpm10030093. [PMID: 32824824 PMCID: PMC7565405 DOI: 10.3390/jpm10030093] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 08/10/2020] [Accepted: 08/12/2020] [Indexed: 12/21/2022] Open
Abstract
The contribution of genetic ancestry on chronic obstructive pulmonary disease (COPD) predisposition remains unclear. To explore this relationship, we analyzed the associations between 754,159 single nucleotide polymorphisms (SNPs) and risk of COPD (n = 214 cases, 193 healthy controls) in Talca, Chile, considering the genetic ancestry and established risk factors. The proportion of Mapuche ancestry (PMA) was based on a panel of 45 Mapuche reference individuals. Five PRDM15 SNPs and two PPP1R12B SNPs were associate with COPD risk (p = 0.05 to 5×10-4) in those individuals with lower PMA. Based on linkage disequilibrium and sliding window analyses, an adjacent PRDM15 SNPs were associated with COPD risk in the lower PMA group (p = 10-3 to 3.77×10-8). Our study is the first to report an association between PPP1R12B and COPD risk, as well as effect modification between ethnicity and PRDM15 SNPs in determining COPD risk. Our results are biologically plausible given that PPP1R12B and PRDM15 are involved in immune dysfunction and autoimmunity, providing mechanistic evidence for COPD pathogenesis and highlighting the importance to conduct more genome wide association studies (GWAS) in admixed populations with Amerindian descent.

Gender differences in COPD management in a Sicilian general practice setting: a cohort study evaluating the impact of educational interventions. ERJ Open Res 2020; 6:00279-2020. [PMID: 32832528 PMCID: PMC7430144 DOI: 10.1183/23120541.00279-2020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Accepted: 05/21/2020] [Indexed: 01/30/2023] Open
Abstract
Aim The aim of this study was to measure gender differences among COPD patients' quality of care (QOC) before and after two educational interventions in Southern Italy. Methods In this prospective cohort study, COPD patients were identified from primary care electronic medical records (EMRs). Twelve process indicators concerning diagnosis, preventative measures and therapeutic processes were developed as a measure of QOC. Educational interventions consisted of clinical seminars and audits on COPD QOC at baseline, and at 12 and 24 months. QOC indicators were stratified by gender: odds ratios (ORs) (males as reference group) of having a good QOC indicator were calculated at baseline, 12 and 24 months, with 95% confidence intervals (CIs) using hierarchical generalised linear models. Results Of 46 326 people registered in the EMRs, 1463 COPD patients (3.1%) were identified, of which 37% were women. QOC indicators reflecting best practice 24 months after the educational programme were generally not different to baseline, often favouring men. On the other hand, the composite global QOC indicator suggested that while a good overall QOC at baseline was significantly higher in men than women (OR: 0.74; 95% CI: 0.57–0.96), it became nonsignificant at 24 months (OR: 0.96; 95% CI: 0.72–1.29). Conclusions Specific QOC indicators among COPD patients often favoured men. However, several gender disparities seen at baseline disappeared at 24 months, suggesting that even general educational interventions which do not target gender can improve the gender disparity in QOC. This observational study shows that quality of care (QOC) is better among male COPD patients in primary care. Planned educational interventions over 24 months abolished gender difference in global QOC, although not in all QOC items.https://bit.ly/3cfwPST
