Anxiety and depression in COPD: current understanding, unanswered questions, and research needs

Trends in the prevalence and incidence of chronic obstructive pulmonary disease among adults aged ≥50 years in the United States, 2000-2020

Background

Understanding the trends of the prevalence and incidence rate of chronic obstructive pulmonary disease (COPD) is vital for improving the control and prevention of COPD. We aimed to examine the trends in the prevalence and incidence rate of COPD among adults aged 50 years or older in the United States during 2000-2020.

Methods

Utilizing data from the Health and Retirement Study, we analyzed COPD prevalence across survey waves and calculated COPD incidence rates between consecutive interview waves, stratified by gender and race. We employed joinpoint regression models to investigate trends in COPD prevalence and incidence.

Results

The individuals reporting COPD are more likely to be women and Caucasians. The age-adjusted prevalence of COPD among adults aged 50 years and over showed an increasing trend throughout the study period, spanning from 9.02% in 2000 to 9.88% in 2020 (average biennial percent change [ABPC] = 0.41, 95% confidence interval [CI]: 0.10, 0.71; p = 0.01). The age-adjusted incidence rate of COPD among adults aged 50 and over showed a decreasing trend throughout the study period 1031.1 per 100,000 person-years in 2000 to 700.5 per 100,000 person-years in 2020 (ABPC = -1.63, 95% CI: -2.88, -0.36; p = 0.02).

Conclusion

Our findings indicate a rising prevalence of COPD among older adults in the United States since 2000, while the incidence rate of COPD has shown a declining trend.

Sleep Deficiency, Sleep Apnea, and Chronic Lung Disease

With sleep occupying up to one-third of every adult's life, addressing sleep is essential to overall health. Sleep disturbance and deficiency are common in patients with chronic lung diseases and associated with worse clinical outcomes and poor quality of life. A detailed history incorporating nocturnal respiratory symptoms, symptoms of obstructive sleep apnea (OSA) and restless legs syndrome, symptoms of anxiety and depression, and medications is the first step in identifying and addressing the multiple factors often contributing to sleep deficiency in chronic lung disease. Additional research is needed to better understand the relationship between sleep deficiency and the spectrum of chronic lung diseases.

The Obesity Paradox in Pulmonary Rehabilitation: Relevance and Implications to Clinical Practice

Pulmonary rehabilitation (PR) increases exercise capacity, reduces dyspnea, and improves quality of life (QoL) in patients with chronic obstructive pulmonary disease (COPD). Patients requiring PR can present with multiple comorbidities. One of the most common comorbidities is obesity. The prevalence of obesity in patients with COPD is increasing at an alarming rate. To date the efficacy of PR to ameliorate obesity in patients with COPD is unclear. Obesity in patients with COPD is associated with increased morbidity and mortality compared to patients without obesity. However, the benefits of obesity paradox in lower mortality rate health-related QoL and health care utilization remain unclear. This review discusses the challenges of prescribing PR to patients with obesity and COPD. In addition, the definition of and the potential challenges and benefits of the obesity paradox in patients with COPD will be discussed. Treatment strategies that include combining PR with lifestyle management, individually tailored nutritional advice, pharmacotherapy, and surgery need to be tested in prospective, randomized controlled trials. The challenges of providing complex care, prioritizing patient needs, and future directions will also be discussed for patients with obesity and COPD.

Research of related factors of depression in COPD patients

We aimed to investigate the related risk factors of depression in patients with chronic obstructive pulmonary disease (COPD) to detect depressed patients early and perform timely intervention to improve the disease prognosis of chronic obstructive pulmonary disease. This cross-sectional study included COPD patients who were discharged from the First People's Hospital of Hefei, China from October 2018 to October 2019, and all participants were diagnosed with COPD according to the Global Initiative for Chronic Obstructive Pulmonary Disease. There was no COPD exacerbation during follow-up 1 month after discharge. Psycho-cognitive disorders, psychiatric disorders or other conditions causing psychiatric symptoms were excluded. We divided stable patients with chronic obstructive pulmonary disease into depression group (HAM-D 24 ≥ 8) and non-depression group (<8), and compared the sociodemographic data, clinical characteristics and serum inflammatory parameters between the 2 groups. In this cross-sectional study, 100 eligible COPD patients were initially recruited, 64 of whom completed all the programs. Univariate logistic regression analysis, female, chronic obstructive pulmonary disease assessment test (CAT) score, serum interferon alpha-a (IFN-α) level, and low smoking index were associated with depression in patients with chronic obstructive pulmonary disease. Multivariate logistic regression analysis showed that high serum IFN-α level (OR = 1.099, 95% CI: 1.010-1.196; P = .028), high CAT score (OR = 1.250, 95% CI: 1.052-1.484; P = .011) and low smoking index (OR = 10.154, 95% CI: 1.886-54.664; P = .007) were significant risk factors for depression in patients with chronic obstructive pulmonary disease. Our findings suggest that high serum IFN-α levels, and high CAT scores are risk factors for comorbid depression in COPD patients. Continuous high-dose smoking may aggravate the primary disease and ultimately aggravate depression.

Dynamic changes in quality of life in older patients with chronic obstructive pulmonary disease: a 7-year follow up

PURPOSES

Chronic obstructive pulmonary disease (COPD) is a major cause of the rapid decline of health-related quality of life (HRQoL), associated with accelerated frailty in older populations. This study aimed to analyse the long-term dynamic changes of HRQoL and the predictive factors for the rapid decline of HRQoL in older patients with COPD.

METHODS

Overall 244 patients with COPD, aged ≧ 65 years from one medical centre were enrolled between March 2012 and July 2020. Further, we prospectively assessed HRQoL scores with utility values, using EuroQol Five-Dimension (EQ-5D) questionnaires. Additionally, long-term dynamic changes in HRQoL were analysed using the Kernel smoothing method and examined the factors contributing to the deterioration of HRQoL using a linear mixed effects model.

RESULTS

Older patients with COPD with forced expiration volume (FEV1) < 50% of prediction entered the phase of rapid and continuous decline of HRQoL ~ 2 years after enrolment, but patients with FEV1 ≥ 50% of prediction without rapidly declined HRQoL during 7 years follow up. Therefore, FEV1 < 50% of prediction is a novel predictor for the rapid decline of HRQoL. The course of rapidly declining HRQoL occurred, initially in the usual activities and pain/discomfort domains, followed by the morbidity, self-care, and depression/anxiety domains ~ 2 and 4 years after enrolment, respectively. The mixed effects model indicated that both FEV1 < 50% of prediction and a history of severe acute exacerbation (SAE) requiring hospitalisation were contributing factors for deterioration in HRQoL .

CONCLUSIONS

Both FEV1 < 50% of prediction and exacerbations requiring hospitalisation were contributing factors for the deterioration of HRQoL in long-term follow up. Additionally, FEV1 < 50% of prediction was a novel predictor for patients entering the phase of rapid decline of HRQoL.

Effect of pulmonary rehabilitation duration on exercise capacity and health-related quality of life in people with chronic obstructive pulmonary disease (PuRe Duration Trial): A randomized controlled equivalence trial

BACKGROUND AND OBJECTIVE

There is no strong evidence on the optimal duration of pulmonary rehabilitation (PR) programmes. The aim of the study was to determine whether an 8-week PR programme was equivalent to a 12-week PR programme in improving endurance exercise capacity in people with chronic obstructive pulmonary disease (COPD).

METHODS

Participants with COPD were randomized to either an 8-week (8-wk Group) or 12-week (12-wk Group), twice weekly, supervised PR programme consisting of endurance and strength training and individualized self-management education. Between group comparisons were made at completion of each programme (i.e., week 8 or week 12), for both programmes at week 12, and at 6-12-month follow-up. The primary outcome was endurance exercise capacity measured by the endurance shuttle walk test (ESWT) with the minimally important difference of 186 s set as the equivalence limit.

RESULTS

Sixty-six participants [mean (SD); age 69 (7) years, FEV1 48 (17) %predicted] were randomized (33 per group). Between-group comparisons demonstrated that the ESWT time was equivalent for the 12-wk Group compared to the 8-wk Group at programme completion [mean (95% CI)] [71 s (-61 to 203)], week 12 [70 s (-68 to 208)], and 6-12-month follow-up [93 s (-52 to 239)], though superiority of the 12-wk Group could not be ruled out at each time point.

CONCLUSION

Equivalence was shown between 8-and 12-week PR programmes for endurance exercise capacity, but superiority could not be ruled out for the 12-wk Group. Decisions about programme duration may depend on local waitlist times, healthcare budgets and patient preference.

Cross-sectional association between posttraumatic stress and cognition is moderated by pulmonary functioning in world trade center responders

BACKGROUND

Posttraumatic stress disorder (PTSD) symptomatology and poorer pulmonary function are highly prevalent psychiatric and medical conditions. In the present study, we tested for the individual, additive, and modifying associations of PTSD symptomatology and pulmonary function with cognitive performance.

METHODS

In this cross-sectional study, a total of 1,401 World Trade Center (WTC) responders (mean age = 53, SD = 8 years, 92% males) participated in the study. Cogstate assessment measured cognitive performance. PTSD symptomatology was measured using the trauma-specific version of the posttraumatic stress disorder checklist (PCL-17) adapted for the WTC attacks. The 1-second forced expiratory volume and forced vital capacity (FEV1/FVC) ratio was used to measure pulmonary function. Linear regressions with cognitive performance as the outcome were conducted to assess individual, additive, and moderating associations of PTSD symptomatology and pulmonary function.

RESULTS

Higher PTSD symptomatology and poorer pulmonary function were negatively associated with cognitive performance. A 10% increase on the FEV1/FVC ratio moderated the association between PTSD symptomatology and cognition, whereby its association with cognition was stronger when PTSD symptomatology was higher (est. = 0.01, 95%CI = 0.004, 0.01, p < 0.001). When stratified by responder type, these associations persisted in trained (est. = 0.01, 95%CI = 0.01, 0.02, p < 0.001), but not in non-trained (est. = 0.004, 95% C.I. = -0.01, 0.02, p = 0.39) responders.

CONCLUSIONS

In the presence of higher PTSD, better pulmonary functioning is associated with better cognitive performance. Early intervention efforts to mitigate preventable cognitive decline in high-risk populations should be studied, especially since intervention in one modality may have an impact on others.

[Effects of gender on pulmonary rehabilitation outcomes in patients with COPD]

INTRODUCTION

COPD has become more prevalent among women, revealing a specific feminine phenotype. Women experience greater dyspnea and a more impaired quality of life. The main objective of this study was to assess the effect of gender on dyspnea during a pulmonary rehabilitation program (PRP).

METHODS

Retrospective study including COPD patients having participated in PRPs. The following data were analyzed according to gender before and after a PRP: dyspnea, quality of life, anxiety and depression, exercise capacity, muscle function (quadriceps and inspiratory muscles).

RESULTS

More than 500 patients (252 men and 252 women) were included. We did not find a significant effect of gender on the evolution of dyspnea, anxiety or depressive disorders, exercise capacity, inspiratory muscle strength, or overall quality of life score. That said, we found a possible effect on the sub-scores of the quality of life questionnaire, and regarding quadriceps strength. All criteria improved during the program in both groups.

CONCLUSIONS

During a PRP, gender does not impact the evolution of dyspnea. While women may nonetheless benefit to a greater extent in terms of quality of life sub-scores (impact, activities, symptoms) and quadriceps strength, these results still require confirmation.

The Effect of Spiritual Well-Being on Self-care Agency in Chronic Obstructive Pulmonary Patients in Turkey: The Mediating Role of Psychological Resilience

The aim of the present study was to determine the mediator role of psychological resilience in examining the effect of spiritual well-being on self-care agency in Chronic Obstructive Pulmonary Patients (COPD). The present cross-sectional and correlational study has a descriptive design, and it was conducted with 200 COPD patients admitted to the chest diseases outpatient clinic of a university hospital. "Spiritual Well-Being Scale (FACIT Sp-12)," "Brief Resilience Scale (BRS)" and "Self-Care Agency Scale (SCAS)" were used in the study for collecting the research data. STROBE recommendations were followed while reporting this study. FACIT Sp-12 total score average, the BRS total average score and the ASAS total average score of the patients were found to be 29.88 ± 1.44, 21.47 ± 66.31, and 84.81 ± 14.69, respectively. In addition, it was determined that both spiritual well-being (β = 0.170) and psychological resilience (β = 0.777) positively affected self-care agency. SCAS mediates the effect of FACIT-Sp-12 on self-care agency and strengthens the positive effect of FACIT-Sp-12 on self-care agency (β = 0.843). It was seen that the predictive effect of these two variables in explaining self-care power was 60%. Spiritual well-being and self-care agency of the COPD patients were found to be moderate, and the psychological resilience was found to be high. In addition, spiritual well-being was found to affect self-care agency directly and the mediating role of psychological resilience indirectly.

Obstructive respiratory disease in U.S. veterans: Prevalence, characteristics, and health burden

OBJECTIVE

To examine the psychiatric and physical health burden of obstructive respiratory disease in a nationally representative sample of U.S. Veterans.

METHODS

Secondary data analyses were conducted using data from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of U.S. Veterans. Participants self-reported health professional-diagnosed obstructive respiratory disease (i.e., asthma, chronic bronchitis or chronic obstructive pulmonary disease). Veterans who reported obstructive respiratory disease (n = 502) were compared to veterans without this disease but with at least one or more other medical conditions-controls (n = 3169) on measures of sociodemographic, trauma, psychiatric, and physical health characteristics. Multivariable regression analyses examined independent associations between obstructive respiratory disease and psychiatric conditions and physical characteristics.

RESULTS

A total 12.5% of the sample reported a diagnosis of obstructive respiratory disease. Compared to controls, veterans with obstructive respiratory disease were more likely to be female, unmarried/partnered, lower income, residing in the Midwest, receiving VA healthcare, and had greater lifetime and childhood trauma burden. In adjusted analyses, veterans with respiratory disease had 47-91% greater odds of screening positive for current posttraumatic stress, major depressive, and generalized anxiety disorders, and had 48% greater odds of current suicide ideation. They were also more likely to have lifetime nicotine use disorder and had more medical comorbidities and more severe somatic symptoms.

CONCLUSIONS

Obstructive respiratory disease is prevalent among U.S. veterans and associated with significant mental and physical health burden. Results highlight the need for timely screening and treatment for psychiatric and medical conditions that are highly comorbid with obstructive respiratory disease in this population.

Apocynin Prevents Cigarette Smoke-Induced Anxiety-Like Behavior and Preserves Microglial Profiles in Male Mice

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death globally and is primarily caused by cigarette smoking (CS). Neurocognitive comorbidities such as anxiety and cognitive impairments are common among people with COPD. CS-induced lung inflammation and oxidative stress may "spill-over" into the systemic circulation, driving the onset of these comorbidities. We investigated whether a prophylactic treatment with the NADPH Oxidase 2 (NOX2) inhibitor, apocynin, could prevent CS-induced neurocognitive impairments. Adult male BALB/c mice were exposed to CS (9 cigarettes/day, 5 days/week) or room air (sham) for 8 weeks with co-administration of apocynin (5 mg/kg, intraperitoneal injection once daily) or vehicle (0.01% DMSO in saline). Following 7 weeks of CS exposure, mice underwent behavioral testing to assess recognition and spatial memory (novel object recognition and Y maze, respectively) and anxiety-like behaviors (open field and elevated plus maze). Mice were then euthanized, and blood, lungs, and brains were collected. Apocynin partially improved CS-induced lung neutrophilia and reversed systemic inflammation (C-reactive protein) and oxidative stress (malondialdehyde). Apocynin exerted an anxiolytic effect in CS-exposed mice, which was associated with restored microglial profiles within the amygdala and hippocampus. Thus, targeting oxidative stress using apocynin can alleviate anxiety-like behaviors and could represent a novel strategy for managing COPD-related anxiety disorders.

Examining the Impact of Social Support on Psychological Well-Being Among Canadian Individuals With COPD: Implications for Government Policies

Chronic obstructive pulmonary disease (COPD) is a significant respiratory disease and is globally ranked as the third leading cause of death. In Canada, the direct healthcare costs associated with COPD are estimated to be $1.5 billion annually. This study utilized quantitative analyses to examine the impact of specific dimensions of social support, namely, guidance, reliable alliance, reassurance of worth, attachment, and social integration within a clinically identified population of individuals with COPD who exhibit symptoms of depression and anxiety. The study was based on the Social Provisions Theory and stress-buffering hypothesis, utilizing large-scale population data from Statistics Canada's 2012 Canadian Community Health Survey (CCHS) Mental Health component. On a national scale, individuals were more likely to report a decreased sense of belonging to a group of friends (social integration) and struggle to depend on others in stressful times (reliable alliance) while experiencing symptoms of anxiety and depression. These findings underscore the potential benefits of integrating peer support, socialization initiatives, and caregiver training into clinical programs designed for individuals with COPD.

Management of Refractory Chronic Obstructive Pulmonary Disease: A Review

Chronic obstructive pulmonary disease (COPD) is a common condition with an estimated prevalence of 12% in adults over the age of 30 years worldwide. COPD is a leading cause of morbidity and mortality globally, with a substantial economic and social burden. There are an estimated 3 million deaths annually due to COPD. However, most of the patients with COPD respond to routine interventions like bronchodilator therapy, assessing supplemental oxygen needs, smoking cessation, vaccinations, and pulmonary rehabilitation. There is a significant number of patients who unfortunately progress to have persistent symptoms despite these interventions. Refractory COPD is not yet formally defined. Patients with severe persistent symptoms or exacerbations despite appropriate care can be considered to have refractory COPD. Managing refractory COPD needs a multidimensional approach. In this review article, we will discuss essential interventions like ensuring adequate inhaler techniques, exploring the need for non-invasive ventilatory support, use of chronic antibiotics and phosphodiesterase inhibitors to advanced therapies like bronchoscopic lung volume reduction surgery, and the upcoming role of anti-IL5 agents in managing patients with refractory COPD. We will also discuss non-pharmacologic interventions like psycho-social support and nutritional support. We will conclude by discussing the palliative care aspect of managing patients with refractory COPD. Through this review article, we aim to better the approach to managing patients with refractory COPD and discuss new upcoming therapies.

Rate of severe exacerbations, healthcare resource utilisation and clinical outcomes in patients with COPD in low-income and middle-income countries: results from the EXACOS International Study

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.

Effect of respiratory muscle training in patients with stable chronic obstructive pulmonary disease: A systematic review and meta-analysis

Objectives

Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory disorder characterized by progressive airflow limitation. This meta-analysis aims to evaluate the effectiveness of respiratory muscle training (RMT) on key pulmonary function parameters, inspiratory muscle strength and quality of life in patients with stable COPD.

Methods

A comprehensive search was conducted in the databases including PubMed, Cochrane, Web of Science, Embase, and ClinicalTrials.gov, from their inception to June 12, 2023. Randomized controlled trials (RCTs) evaluating the impact of RMT on stable COPD were included for meta-analysis.

Results

In total, 12 RCTs involving 453 participants were included in the meta-analysis. RMT demonstrated a significant increase in maximal inspiratory pressure (PImax, MD, 95% CI: 14.34, 8.17 to 20.51, P < 0.001) but not on maximal expiratory pressure (PEmax). No significant improvement was observed in 6-Min walk test (6MWT), dyspnea, forced expiratory volume in 1 s (FEV1), forced vital capacity ratio (FVC) and quality of life between RMT and control groups. However, subgroup analysis revealed a significant negative effect of RMT alone on FEV1/FVC (MD, 95% CI: 2.59, -5.11 to -0.06, P = 0.04). When RMT was combined with other interventions, improvements in FEV1/FVC and FEV1 were found, although not statistically significant.

Conclusion

RMT can effectively improve maximal inspiratory pressure in stable COPD patients, but the effect is slight in improving lung function, dyspnea and quality of life. It is recommended to combine with other treatment strategies to comprehensively improve the prognosis of COPD patients.

Psychometric properties of the Hospital Anxiety and Depression Scale (HADS) in individuals with stable chronic obstructive pulmonary disease (COPD): a systematic review

PURPOSE

The Hospital Anxiety and Depression Scale (HADS) is used to assess anxiety and depression in individuals with chronic obstructive pulmonary disease (COPD); however, its measurement properties lack critical appraisal. We aimed to summarize and critically appraise the validity, reliability, and responsiveness of the HADS in COPD.

MATERIALS AND METHODS

Five electronic databases were searched. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines were used to assess the methodological and evidence quality in the selected studies.

RESULTS

Twelve studies assessed the psychometric properties of the HADS-Total and its subscales HADS-Anxiety and HADS-Depression in COPD. High-quality evidence supported the structural and criterion validity of the HADS-A, the internal consistency of the HADS-T, HADS-A, and HADS-D with Cronbach's alpha values of 0.73-0.87, and before-after treatment responsiveness of HADS-T and its subscales (minimal clinically important difference = 1.4-2; effect size = 0.45-1.40). Moderate-quality evidence supported the test-retest reliability of the HADS-A and HADS-D with excellent coefficient values of 0.86-0.90.

CONCLUSIONS

The HADS-A is recommended for use in individuals with stable COPD. The lack of high-quality evidence on the validity of the HADS-D and HADS-T prevented drawing robust conclusions about their clinical utility in COPD.

Feasibility and Design Factors for Home-Based Pulmonary Rehabilitation of Patients With Chronic Obstructive Pulmonary Disease and Chronic Lung Diseases Based on a People-Object-Environment Framework: Qualitative Interview Study

BACKGROUND

The feasibility of implementing home-based pulmonary rehabilitation (PR) can be assessed from the perspectives of patients with chronic lung disease and health care professionals involved in PR.

OBJECTIVE

Through a qualitative inquiry using interviews and the adoption of the people-object-environment framework, this study aims to understand the influences of interpersonal, environmental, and situational factors on the perceptions and considerations of individuals involved in home-based PR for patients with chronic lung disease.

METHODS

One-on-one interviews were conducted with 20 patients with chronic lung disease and 20 health care professionals for investigating their attitudes and opinions based on their experiences regarding home-based PR as well as for identifying the key factors affecting the benefits and drawbacks of such therapies. This study further evaluates the feasibility of using digital tools for medical diagnosis and treatment by examining the technology usage of both parties.

RESULTS

The 4 key issues that all participants were the most concerned about were as follows: distance to outpatient medical care, medical efficiency, internet connectivity and equipment, and physical space for diagnosis and treatment. Interviews with patients and health care professionals revealed that the use of technology and internet was perceived differently depending on age and area of residence. Most participants reported that digital tools and internet connectivity had many benefits but still could not solve all the problems; moreover, these same digital tools and network transmission could lead to problems such as information security and digital divide concerns. This study also emphasizes the significant impact of human behavior and thinking on shaping the design of health care interventions and technologies. Understanding user perspectives and experiences is crucial for developing effective solutions for unmet needs.

CONCLUSIONS

The results of this study indicate that despite the different perspectives of patients and health care professionals, their considerations of the key issues are very similar. Therefore, the implementation of plans related to telemedicine diagnosis, treatment, or rehabilitation should take the suggestions and considerations of both parties into account as crucial factors for telehealth care design.

Effect of experimental modulation of mood on exertional dyspnoea in chronic obstructive pulmonary disease

BACKGROUND AND OBJECTIVE

Dyspnoea is a debilitating symptom in individuals with chronic obstructive pulmonary disease (COPD) and a range of other chronic cardiopulmonary diseases and is often associated with anxiety and depression. The present study examined the effect of visually-induced mood shifts on exertional dyspnoea in individuals with COPD.

METHODS

Following familiarization, 20 participants with mild to severe COPD (age 57-79 years) attended three experimental sessions on separate days, performing two 5-min treadmill exercise tests separated by a 30-min interval on each day. During each exercise test, participants viewed either a positive, negative or neutral set of images sourced from the International Affective Picture System (IAPS) and rated dyspnoea or leg fatigue (0-10). Heart rate (HR) and peripheral oxygen saturation (SpO2 ) were measured at 1-min intervals during each test. Mood valence ratings were obtained using Self-Assessment Manikin (SAM) scale (1-9).

RESULTS

Mood valence ratings were significantly higher when viewing positive (end-exercise mean ± SEM = 7.6 ± 0.3) compared to negative IAPS images (2.4 ± 0.3, p < 0.001). Dyspnoea intensity (mean ± SEM = 5.8 ± 0.4) and dyspnoea unpleasantness (5.6 ± 0.3) when viewing negative images were significantly higher compared to positive images (4.2 ± 0.4, p = 0.004 and 3.4 ± 0.5, p = 0.003). Eighty-five percent of participants (n = 17) met the minimal clinically important difference (MCID) criteria for both dyspnoea intensity and unpleasantness. HR, SpO2 and leg fatigue did not differ significantly between conditions.

CONCLUSION

These findings indicate that the negative affective state worsens dyspnoea in COPD, thereby suggesting strategies aimed at reducing the likelihood of negative mood or improving the mood may be effective in managing morbidity associated with dyspnoea in COPD.

Gender difference on the mediation effects of filial piety on the association between chronic obstructive pulmonary disease and depressive symptoms in older adults: A community-based study

Filial piety is viewed as strong family support for older Chinese people, and strongly associated with depressive symptoms. It is unknown if there exists gender difference in the mediation effects of filial piety on the relationship between chronic obstructive pulmonary disease (manifested as lung function) and depression. We investigated whether filial piety mediates the association between lung function and depression in community-dwelling older men and women using the Healthy Aging Longitudinal Study in Taiwan (HALST). Community dwelling adults aged 65 and above were analyzed. Pulmonary function, depressive symptoms, and filial piety expectation (FPE) and receipt of filial piety (RFP) were collected. The interaction and mediation of filial piety between lung function and depression was analyzed. We found that in older men, forced expiratory volume in the first second (FEV1) was inversely correlated with depression (β = -0.1281, p = 0.004) with no mediation effect of FPE. In older women, FEV1 was negatively associated with FPE, but FPE did not increase the risk of depression (β = 0.0605, p = 0.12). In both older men and women, FEV1 was negatively associated with RFP, while RFP reduced the risk of depression (p< 0.001). In older women, the correlation between FEV1 was complete mediation of RFP. Results indicate that feelings of insufficient filial piety may increase the likelihood of depression, especially in elderly women with worse lung function. Although modest, the main mediation effect of filial piety was improvement of lung function in older subjects, which might decrease depression.

From treatable traits to GETomics in airway disease: moving towards clinical practice

The treatable traits approach represents a strategy for patient management. It is based on the identification of characteristics susceptible to treatments or predictive of treatment response in each individual patient. With the objective of accelerating progress in research and clinical practice relating to such a treatable traits approach, the Portraits event was convened in Barcelona, Spain, in November 2022. Here, while reporting the key concepts that emerged from the discussions during the meeting, we review the current state of the art related to treatable traits and chronic respiratory diseases management, and we describe the possible actions that clinicians can take in clinical practice to implement the treatable traits framework. Furthermore, we explore the new concept of GETomics and the new models of research in the field of COPD.

The impact on thirty day readmissions for patients hospitalized for acute exacerbations of chronic obstructive pulmonary disease admitted to an observation unit versus an inpatient medical unit: A retrospective observational study

OBJECTIVES

We aimed to evaluate the utility of an Observation Unit (OU) in management of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and to identify the clinical characteristics of patients readmitted within 30-days for AECOPD following index admission to the OU or inpatient floor from the OU.

METHODS

This is a retrospective observational study of patients admitted from January to December 2017 for AECOPD to an OU in an urban-based tertiary care hospital. Primary outcome was rate of 30-day readmission after admission for AECOPD for patients discharged from the OU versus inpatient service after failing OU management. Regression analyses were used to define risk factors.

RESULTS

163 OU encounters from 92 unique patients were included. There was a lower readmission rate (33%) for patients converted from OU to inpatient care versus patients readmitted after direct discharge from the OU (44%). Patients with 30-day readmissions were more likely to be undomiciled, with history of congestive heart failure (CHF), pulmonary embolism (PE), or had previous admissions for AECOPD. Patients with >6 annual OU visits for AECOPD had higher rates of substance abuse, psychiatric diagnosis, and prior PE; when these patients were excluded, the 30-day readmission rate decreased to 13.5%.

CONCLUSION

Patients admitted for AECOPD with a history of PE, CHF, prior AECOPD admissions, and socioeconomic deprivation are at higher risk of readmission and should be prioritized for direct inpatient admission. Further prospective studies should be conducted to determine the clinical impact of this approach on readmission rates.

Psychophysical and Social Functioning of Patients with Chronic Obstructive Lung Disease and Depression

The relationship between depression and chronic obstructive pulmonary disease (COPD) is not fully understood. The comorbidity rate ranges from 18 to 84%, and depression is closely related to chronic inflammation, which affects how patients and the people around them perceive their condition. This study aims to examine the relationship between the psychophysical and social functioning of COPD patients who have been diagnosed with depression and the therapeutic benefits of selective serotonin reuptake inhibitors (SSRIs). This prospective study enrolled primary care patients diagnosed with COPD and depression. The entire period of this research was 3 years. The research was conducted at the Primary Health Center, Kragujevac, Serbia, in 87 patients for 8 weeks. The Hamilton Depression Scale (HAM-D) and Questionnaire for Quality of Life and Life Satisfaction Short Form (Q-LES-Q-SF) were used for psychiatric assessment. A positive correlation was found between the psychophysical and social functioning of the participants after 8 weeks of treatment with SSRIs. Based on the value of the phi correlation coefficient (phi = 0.5) obtained using the χ2 test, a large influence was observed in terms of life satisfaction and physical health (p < 0.05). In terms of physical functioning by gender, based on the value of the Pearson's coefficient (r) obtained with the χ2 test, it was shown that physical functioning was superior in the female respondents (p < 0.05). Treatment was found to improve depression in COPD after 8 weeks of therapy.

Anxiety and post-traumatic stress disorders in patients with chronic respiratory diseases

PURPOSE OF REVIEW

This brief critical review evaluates recent research on the impact of anxiety disorders and post-traumatic stress disorders (PTSD) on patients with chronic obstructive pulmonary disease (COPD) and asthma. In these patients, untreated anxiety and PTSD exacerbate acute symptoms, increase disability and impair quality of life. Therefore, effective interventions are also reviewed.

RECENT FINDINGS

Anxiety disorders and PTSD are prevalent in COPD and asthma, worsen symptoms in acute exacerbations, and increase morbidity and healthcare utilization. Pulmonary rehabilitation (PR), cognitive behavioural therapy and pharmacological therapy are each effective in COPD patients with anxiety or PTSD. However, very little work examined therapy for combined anxiety and PTSD in patients with either COPD or asthma.

SUMMARY

Despite the high prevalence of anxiety disorder or PTSD in patients with chronic respiratory diseases, a paucity of literature remains demonstrating the efficacy of pharmacological therapies for these conditions. This review highlights the promising benefits of PR on anxiety, but prospective trials are needed to demonstrate the efficacy of interventions with PTSD alone, or with concomitant anxiety.

Prevalence and Impact of Social Frailty in Patients with Chronic Obstructive Pulmonary Disease

Background

Patients with chronic obstructive pulmonary disease (COPD) are more inclined to have a high level of social vulnerability due to their physical and psychological burden. However, to date, there have been no study on social frailty in patients with COPD. This study aimed to investigate the prevalence, characteristics, and impact of social frailty in patients with COPD.

Methods

Social frailty was assessed using five items in a questionnaire. A patient was diagnosed with social frailty if responses to two or more items were positive. Four hundred and five patients with COPD were assessed for social frailty, dyspnea, and appetite. We also prospectively examined the number of acute exacerbation and unexpected hospitalization for 1 year.

Results

Thirty-six percent of patients with COPD had social frailty. They had reduced appetite and more severe dyspnea [Simplified Nutritional Appetite Questionnaire score: odds ratio (OR) 0.81, 95% confidence interval (CI) 0.69‒0.95, p < 0.01; modified Medical Research Council score: OR 1.42, 95% CI 1.05‒1.93, P = 0.02] than patients without social frailty. Social frailty was not a risk factor for moderate acute exacerbation of COPD but a risk factor for severe acute exacerbation and all-cause unexpected hospitalization (severe acute exacerbation: β, standardized regression coefficient: 0.13, 95% CI 0.01‒0.25, P = 0.04, unexpected hospitalization: β 0.17, 95% CI 0.05‒0.29, P = 0.01).

Conclusion

The prevalence of social frailty is 36%; however, social frailty has a marked clinical impact in patients with COPD.

Anxiety and Depression Among US Nursing Home Residents with Chronic Obstructive Pulmonary Disease

Background

Chronic obstructive pulmonary disease (COPD) is highly prevalent among nursing home residents; however, few studies have focused on the psychological impact of this clinically significant condition on nursing home residents.

Objective

We examine the prevalence of, and factors associated with, anxiety and depression in nursing home residents with COPD.

Methods

Using the US 2018 Minimum Dataset (MDS), we conducted a cross-sectional study among 239,615 residents aged ≥50 years old in US Medicare/Medicaid certified nursing homes with COPD. Anxiety and depression were diagnosed based on clinical diagnoses, physical examination findings, and treatment orders. Multivariable adjusted Poisson models with a generalized estimating equations approach account for the clustering among residents within nursing homes.

Results

The average age of the study population was 79 years (SD: 10.6), 62.0% were women, and 43.7% had five or more comorbid conditions. In this population, 37.2% had anxiety, 57.6% had depression, and 27.5% had both mental health conditions. Women, current tobacco users, persons 50-64 years old, those who reported having moderate or severe pain, and nursing home residents with multimorbidity were more likely to have anxiety or depression than respective comparison groups.

Conclusion

Anxiety and depression are common among US nursing home residents with COPD. Women, medically complex patients, and those who report having moderate-to-severe pain appear to be more likely to have anxiety and depression. Clinical teams should be aware of these findings when managing nursing home residents with COPD and use various nonpharmacological and medical interventions for the effective management of anxiety and depression. Longitudinal studies evaluating how anxiety and depression affect the management of COPD and related outcomes, and how best to improve the quality of life of nursing home residents with COPD, are warranted.

Predictors of Quality-of-Life Improvement at Different Minimum Clinically Important Difference Values in Patients with Chronic Obstructive Pulmonary Disease after Climatic Rehabilitation Treatment

BACKGROUND

The minimum clinically important difference (MCID) for the St George's Respiratory Questionnaire (SGRQ) is debated in chronic obstructive pulmonary disease (COPD) quality-of-life (QoL) assessments. This study aimed to determine whether there is a difference in predictors of clinically significant improvement between the traditional (value of 4) and newly proposed MCID SGRQ (value of 7) after climatic rehabilitation treatment. Climatic rehabilitation treatment consists of two main parts: climatotherapy, which typically involves the controlled exposure of individuals to natural environmental elements, and climatic rehabilitation, which includes other therapeutic factors such as physical activities as well as educating the patient to change their lifestyle.

METHODS

This study included 90 consecutive patients diagnosed with COPD who underwent structured complex pulmonary rehabilitation in High Tatras, part of the Carpathian Mountains. The examination before and after treatment included spirometry, QoL assessment using the SGRQ, 6 min walk test (6-MWT), and the Borg, Beck and Zung scale.

RESULTS

Patients showed statistically significant improvement after the intervention in FEV1, FEV1/FVC, 6-MWT, (p < 0.001), anxiety scores, depression, and improvement in dyspnoea both before and after the 6-MWT (p < 0.001). For both MCID for SGRQ levels 4 and 7, we confirmed the same predictors of clinical improvement for bronchial obstruction grade (spirometry) and exercise capacity (6-MWT), for quality of life in activity score and total score.

CONCLUSION

The results suggest that both the proposed MCID for SGRQ values could be sufficient to assess the clinical significance of the achieved change in health status when assessing the need for pulmonary rehabilitation comprising climatotherapy in patients with COPD.

The Functional and Psychosocial Consequences of COPD

COPD is a chronic respiratory disease that commonly coexists with other chronic conditions. These comorbidities have been shown to influence overall disease burden and mortality in COPD, and these comorbidities have an important impact on functional status and other psychosocial factors. Mental health disorders, especially anxiety and depression are common comorbidities in COPD. However, the mechanisms and interactions of anxiety and depression in COPD are poorly understood and these conditions are often underdiagnosed. The interplay between anxiety and depression and COPD is likely multifactorial and complex. An obvious mechanism is the expected psychological consequences of having a chronic illness. However, there is increasing interest in other potential biological processes, such as systemic inflammation, smoking, hypoxia, and oxidative stress. Recognition and diagnosis of comorbid anxiety and depression in patients with COPD is often challenging because there is no consensus on the appropriate screening tools or rating scales to use in this patient population. Despite the challenges in accurate assessment of anxiety and depression, there is growing evidence to support that these comorbid mental health conditions in COPD result in worse outcomes, including poor health-related quality of life, increased exacerbations with associated health-care utilization and cost, increased functional disability, and increased mortality. There are limited data of variable quality on effective treatment and management strategies, both pharmacologic and non-pharmacologic, for anxiety and depression in COPD. However, cumulative evidence demonstrates that complex psychological and lifestyle interventions, which include a pulmonary rehabilitation component, may offer the greatest benefit. The high prevalence and negative impact of depression and anxiety highlights the need for comprehensive, innovative, and standardized chronic disease management programs for individuals with COPD.

The COPD Assessment Test (CAT) and Depression: A Longitudinal Analysis During the COVID-19 Pandemic

Purpose

Chronic obstructive pulmonary disease (COPD) is multifaceted, with some patients experiencing anxiety and depression. Depression in COPD has been associated with worse total scores for the COPD assessment test (CAT). Also, CAT score worsening has been observed during the COVID-19 pandemic. The relationship between the Center for Epidemiologic Studies Depression Scale (CES-D) score and CAT sub-component scores has not been evaluated. We investigated the relationship between CES-D score and CAT component scores during the COVD-19 pandemic.

Patients and Methods

Sixty-five patients were recruited. Pre-pandemic (baseline) was defined as 23rd March 2019-23rd March 2020, CAT scores and information related to exacerbations were collected via telephone at 8-week intervals between 23rd March 2020-23rd March 2021.

Results

There were no differences in CAT scores pre- compared to during the pandemic (ANOVA p = 0.97). Total CAT scores were higher in patients with symptoms of depression compared to those without both pre- (p < 0.001) and during-pandemic (eg, at 12 months 21.2 versus 12.9, mean difference = 8.3 (95% CI = 2.3-14.2), p = 0.02). Individual CAT component scores showed significantly higher chest tightness, breathlessness, activity limitation, confidence, sleep and energy scores in patients with symptoms of depression at most time points (p < 0.05). Significantly fewer exacerbations were observed during- compared to pre-pandemic (p = 0.04). We observed that COPD patients with symptoms of depression had higher CAT scores both pre- and during the COVID-19 pandemic.

Conclusion

Presence of depressive symptoms was selectively associated with individual component scores. Symptoms of depression may potentially influence total CAT scores.

Associations of self-reported chronic obstructive pulmonary disease with indicators of economic instability and stress - 16 states, 2017

OBJECTIVES

To examine the association between chronic obstructive pulmonary disease status and indicators of economic instability and stress to better understand the magnitude of these issues in persons with chronic obstructive pulmonary disease.

METHODS

Analyzed 2017 Behavioral Risk Factor Surveillance System data from 16 states that administered the 'Social Determinants of Health' module, which included economic instability and stress measures (N = 101,461). Associations between self-reported doctor-diagnosed chronic obstructive pulmonary disease status and each measure were examined using multinomial logistic models.

RESULTS

Adults with chronic obstructive pulmonary disease were more likely (p < 0.001) than adults without to report not having enough money at month end (21.0% vs. 7.9%) or just enough money (44.9% vs. 37.2%); being unable to pay mortgage, rent, or utility bills (19.2% vs. 8.8%); and that often or sometimes food did not last or could not afford to eat balanced meals (37.9% vs. 20.6%), as well as stress all or most of the time (27.3% vs. 11.6%). Associations were attenuated although remained significant after adjustments for sociodemographic and health characteristics.

DISCUSSION

Financial, housing, and food insecurity and frequent stress were more prevalent in adults with chronic obstructive pulmonary disease than without. Findings highlight the importance of including strategies to address challenges related to economic instability and stress in chronic obstructive pulmonary disease management programs.

Mental health and sleep quality among patients with asthma and COPD

This study aims to compare the mental health of patients with asthma and COPD in terms of anxiety, depression, and sleep quality and to examine the factors that predict sleep disturbance, anxiety, and depressive symptoms.

Methods

This quantitative cross-sectional study employed convenience sampling to enroll 200 patients with asthma and 190 patients with COPD. Data were gathered using a standardized self-administered questionnaire that contained sections on patients' characteristics, the Sleep Quality, Anxiety, and Depression.

Results

The prevalence of poor sleep quality was 17.5 and 32.6% among asthmatic and COPD patients, respectively. The incidence of anxiety and depression was 38 and 49.5% among the patients with asthma, respectively. Their prevalence in patients with COPD was 48.9 and 34.7%, respectively. The multivariate regression analysis showed that marital status (married), BMI, education level (pre-university level), presence of comorbid illness, and depression were significant predictors of PSQI in asthmatic patients. Moreover, age, gender (male), marital status (married), education level (pre-university level), depression, and anxiety were significant predictors of PSQI among COPD participants. According to this study, COPD, and asthma pose serious health risks, including reduced sleep quality, anxiety, and depression.

Attitudes, confidence, barriers and current practice of managing depression in patients with COPD in Saudi Arabia: a national cross-sectional survey

OBJECTIVE

To investigate physicians' perceptions and current practices of identifying and managing depression in patients with chronic obstructive pulmonary disease (COPD).

DESIGN

A cross-sectional online survey was employed between March and September 2022.

SETTINGS

Saudi Arabia.

PARTICIPANTS

1015 physicians, including general practitioners and family, internal and pulmonary medicine specialists.

PRIMARY OUTCOME MEASURES

Physicians' perceptions, confidence, practices and barriers to recognising and managing depression in patients with COPD.

RESULTS

A total of 1015 physicians completed to the online survey. Only 31% of study participants received adequate training for managing depression. While 60% of physicians reported that depression interferes with self-management and worsens COPD symptoms, less than 50% viewed the importance of regular screening for depression. Only 414 (41%) physicians aim to identify depression. Of whom, 29% use depression screening tools, and 38% feel confident in discussing patients' feelings. Having adequate training to manage depression (OR: 2.89; 95% CI: 2.02 to 3.81; p<0.001) and more years of experience (OR: 1.25; 95% CI: 1.08 to 1.45; p=0.002) were associated with the intention to detect depression in COPD patients. The most common barriers linked to recognising depression are poor training (54%), absence of standard procedures (54%) and limited knowledge about depression (53%).

CONCLUSION

The prevalence of identifying and confidently managing depression in patients with COPD is suboptimal, owing to poor training, the absence of a standardised protocol and inadequate knowledge. Psychiatric training should be supported in addition to adopting a systematic approach to detect depression in clinical practice.

Omega-3 Polyunsaturated Fatty Acids in Managing Comorbid Mood Disorders in Chronic Obstructive Pulmonary Disease (COPD): A Review

Chronic obstructive pulmonary disease (COPD) is the third-leading cause of mortality globally, significantly affecting people over 40 years old. COPD is often comorbid with mood disorders; however, they are frequently neglected or undiagnosed in COPD management, thus resulting in unintended treatment outcomes and higher mortality associated with the disease. Although the exact link between COPD and mood disorders remains to be ascertained, there is a broader opinion that inflammatory reactions in the lungs, blood, and inflammation-induced changes in the brain could orchestrate the onset of mood disorders in COPD. Although the current management of mood disorders such as depression in COPD involves using antidepressants, their use has been limited due to tolerability issues. On the other hand, as omega-3 polyunsaturated fatty acids (n-3 PUFAs) play a vital role in regulating inflammatory responses, they could be promising alternatives in managing mood disorders in COPD. This review discusses comorbid mood disorders in COPD as well as their influence on the progression and management of COPD. The underlying mechanisms of comorbid mood disorders in COPD will also be discussed, along with the potential role of n-3 PUFAs in managing these conditions.

Association Between Comorbid Psychiatric Disorders and Persistent Smoking After a Diagnosis of Chronic Obstructive Pulmonary Disease Among Patients Seeking Treatment at a Tertiary Care Hospital in India

Introduction Smoking cessation is the most effective approach to slowing down the progression of chronic obstructive pulmonary disease (COPD). Despite this, almost half of COPD patients continue to smoke after diagnosis. COPD patients with current smoking status are more likely to have concurrent psychiatric comorbidities, for instance, depression and anxiety. These psychiatric disorders can contribute to the persistence of smoking in individuals with COPD. This study aimed to investigate predictors of smoking persistence in COPD patients. Materials and methods A cross-sectional study was conducted in the Outpatient Department (OPD) of the Department of Pulmonary Medicine in a tertiary care hospital from August 2018 to July 2019. Patients with COPD were screened for their smoking status. All subjects were then personally assessed for any psychiatric comorbidity using the Mini International Neuropsychiatric Interview (MINI), the Patient Health Questionnaire-9 (PHQ-9), and the Anxiety Inventory for Respiratory (AIR) Disease. Logistic regression was performed to compute the odds ratio (OR).  Results The study included a total of 87 COPD patients. Of the 87 COPD patients, 50 were current smokers, and 37 were past smokers. COPD patients with psychiatric disorders were four times more likely to continue smoking than those without psychiatric comorbidities (OR: 4.62, 95% CI: 1.46-14.54). The results showed that increasing PHQ-9 scores by one unit in COPD patients increased the likelihood of continuing to smoke by 27 percent. Conclusion In our multivariate analysis, current depression was found as a significant predictor of continued smoking in COPD patients. The present results are consistent with reports from previous research that depressive symptoms are associated with continued smoking in patients with COPD. COPD patients who are currently smoking should be examined for psychiatric disorders and treated concurrently to achieve effective smoking cessation.

Nonpharmacological management of psychological distress in people with COPD

Psychological distress is prevalent in people with COPD and relates to a worse course of disease. It often remains unrecognised and untreated, intensifying the burden on patients, carers and healthcare systems. Nonpharmacological management strategies have been suggested as important elements to manage psychological distress in COPD. Therefore, this review presents instruments for detecting psychological distress in COPD and provides an overview of available nonpharmacological management strategies together with available scientific evidence for their presumed benefits in COPD. Several instruments are available for detecting psychological distress in COPD, including simple questions, questionnaires and clinical diagnostic interviews, but their implementation in clinical practice is limited and heterogeneous. Moreover, various nonpharmacological management options are available for COPD, ranging from specific cognitive behavioural therapy (CBT) to multi-component pulmonary rehabilitation (PR) programmes. These interventions vary substantially in their specific content, intensity and duration across studies. Similarly, available evidence regarding their efficacy varies significantly, with the strongest evidence currently for CBT or PR. Further randomised controlled trials are needed with larger, culturally diverse samples and long-term follow-ups. Moreover, effective nonpharmacological interventions should be implemented more in the clinical routine. Respective barriers for patients, caregivers, clinicians, healthcare systems and research need to be overcome.

Psychometric Validity of the Anxiety Inventory for Respiratory Disease (AIR) Scale in an Indian Sample of Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study

Introduction Researchers have found that chronic obstructive pulmonary disease (COPD) patients suffer from anxiety more than the general population. The Anxiety Inventory for Respiratory Disease (AIR) scale has been primarily used to assess non-somatic anxiety in COPD patients. The validity of AIR among COPD patients has not been evaluated in Indian settings. Therefore, this study was undertaken to determine the validity of AIR in these patients. The study aimed to evaluate concurrent criterion and discriminative validity of the AIR screening scale among patients with COPD using Mini International Neuropsychiatric Interview (MINI) 7.0.2 as the gold standard measure for diagnosing Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) anxiety disorders. Materials and methods A cross-sectional study was conducted in the Outpatients Department (OPD) of the Department of Pulmonary Medicine, All India Institute of Medical Sciences (AIIMS), New Delhi, from August 2018 to July 2019. A total of 100 patients diagnosed with COPD and aged 30 or above were recruited. All participants were further assessed in person by a psychiatry resident doctor using semi-structured proforma, MINI 7.0.2, and AIR Disease (Hindi). Mann-Whitney U and receiver operating characteristic (ROC) curves were conducted. The two-sided p-value of less than 0.05 was considered to be statistically significant. Results To assess the concurrent criterion validity of the AIR scale for screening clinical anxiety disorders, the ROC curve was constructed using MINI diagnoses of anxiety disorder as the gold standard measure. A cut-off score of 5.5 was found to maximize both the specificity and sensitivity of the AIR scale for screening anxiety disorders among COPD patients with COPD. The AIR scale showed a high sensitivity (95%) and specificity (89%) at this cut-point. Conclusion The findings of this study recommend a cut-off score of 5.5 on the AIR scale instead of 8 in previous studies, as maintaining the previously recommended cut-offs in Indian settings may lead to an increase in false negatives. This could have negative consequences for patients seeking treatment. Further studies may be planned to explore the psychometric properties of the current tool in a larger population.

The Impact of Anxiety and Depression in Chronic Obstructive Pulmonary Disease

Patients with COPD (chronic obstructive pulmonary disease) are at a higher risk of comorbid conditions such as anxiety and/or depression, which in turn increase their symptom burden and rehospitalizations compared to the general population. It is important to investigate the pathophysiology and clinical implications of mental health on patients with COPD. This review article finds that COPD patients with anxiety and/or depression have a higher rehospitalization incidence. It reviews the current screening and diagnosis methods available. There are pharmacological and non-pharmacologic interventions available for treatment of COPD patients with depression based on severity. COPD patients with mild depression benefit from pulmonary rehabilitation and cognitive behavioral therapy, whereas patients with severe or persistent depression can be treated with pharmacologic interventions.

Cigarette smoke-induced pulmonary impairment is associated with social recognition memory impairments and alterations in microglial profiles within the suprachiasmatic nucleus of the hypothalamus

Chronic obstructive pulmonary disease (COPD) is a major, incurable respiratory condition that is primarily caused by cigarette smoking (CS). Neurocognitive disorders including cognitive dysfunction, anxiety and depression are highly prevalent in people with COPD. It is understood that increased lung inflammation and oxidative stress from CS exposure may 'spill over' into the systemic circulation to promote the onset of these extra-pulmonary comorbidities, and thus impacts the quality of life of people with COPD. The precise role of the 'spill-over' of inflammation and oxidative stress in the onset of COPD-related neurocognitive disorders are unclear. The present study investigated the impact of chronic CS exposure on anxiety-like behaviors and social recognition memory, with a particular focus on the role of the 'spill-over' of inflammation and oxidative stress from the lungs. Adult male BALB/c mice were exposed to either room air (sham) or CS (9 cigarettes per day, 5 days a week) for 24 weeks and were either daily co-administered with the NOX2 inhibitor, apocynin (5 mg/kg, in 0.01 % DMSO diluted in saline, i.p.) or vehicle (0.01 % DMSO in saline) one hour before the initial CS exposure of the day. After 23 weeks, mice underwent behavioral testing and physiological diurnal rhythms were assessed by monitoring diurnal regulation profiles. Lungs were collected and assessed for hallmark features of COPD. Consistent with its anti-inflammatory and oxidative stress properties, apocynin treatment partially lessened lung inflammation and lung function decline in CS mice. CS-exposed mice displayed marked anxiety-like behavior and impairments in social recognition memory compared to sham mice, which was prevented by apocynin treatment. Apocynin was unable to restore the decreased Bmal1-positive cells, key in cells in diurnal regulation, in the suprachiasmatic nucleus of the hypothalamus to that of sham levels. CS-exposed mice treated with apocynin was associated with a restoration of microglial area per cell and basal serum corticosterone. This data suggests that we were able to model the CS-induced social recognition memory impairments seen in humans with COPD. The preventative effects of apocynin on memory impairments may be via a microglial dependent mechanism.

Associations between depression and anxiety index and frequency of acute exacerbation in chronic obstructive pulmonary disease

BACKGROUND

Comorbidities of chronic obstructive pulmonary disease (COPD) influence clinical characteristics and prognosis.

OBJECTIVES

This study compared the clinical characteristics and exacerbation rate of COPD according to the presence of depression or anxiety.

DESIGN

This study used data from The Korea COPD Subgroup Study (KOCOSS) cohort, a nationwide prospective cohort from 54 medical centers, between April 2012 and 2019.

METHODS

Depression and anxiety were diagnosed with the Beck Depression Inventory and Beck Anxiety Inventory. Negative binomial regression analysis was performed to analyze the frequency of exacerbations in depressed patients and anxiety. Differences in lung function trajectory according to presence of depression/anxiety were analyzed using a linear mixed model.

RESULTS

In all, 2147 patients were enrolled. Depressed patients or anxiety had lower lung function, higher modified Medical Research Council (mMRC) grade, St. George Respiratory Questionnaire (SGRQ) score, and COPD assessment test score, and higher rates of exacerbation in the past year than those without depression/anxiety. Depressed patients had a higher frequency of moderate to severe exacerbations [Incidence Rate Ratio (IRR): 1.57, CI: 1.17-2.11, p = 0.002] and those with anxiety had higher frequencies of moderate to severe (IRR: 1.52, CI: 1.03-2.27, p = 0.038) and severe exacerbations (IRR: 2.13, CI: 1.09-4.15, p = 0.025) during 1-year follow-up compared to those without these comorbidities. The differences in the change in annual forced expiratory volume in 1 seconds (FEV1) over 3 years according to the presence of depression or anxiety were not statistically significant.

CONCLUSION

Depressed and anxious patients showed increased respiratory symptoms and exacerbation rate as well as reduced health-related quality of life, whereas there were no significant differences in changes in lung function between groups with and without depression/anxiety.

Relationship between Functional Status and Type D Personality and Psychiatric Symptoms of Patients with Chronic Obstructive Pulmonary Disease (COPD)

Emotional difficulties, adjustment difficulties, anxiety disorder, paranoid reactions and depression are among the common psychiatric disorders in patients with Chronic Obstructive Pulmonary Disease (COPD). Type D personality is characterized by social inhibition and negative affectivity. Individuals with Type D personality have difficulty in coping with chronic diseases. The aim of our study was to determine type D personality and psychiatric symptoms in patients with COPD. A patient group was formed with 44 people hospitalized with COPD in the Chest Diseases service and a control group was formed with 44 healthy people. A sociodemographic data form, the Beck Depression Inventory, State and Trait Anxiety Inventory, Somatosensory Amplification Scale, Type D Personality Scale, and BODE (Body mass index, Obstruction, Dyspnea, Exercise capacity) index, were used to. According to the results of our study, state and trait anxiety, depression and D-type personality, exaggeration of bodily sensations scale scores were statistically significantly higher in the patient group compared to the control group. Moreover, a high score on the somatosensory amplification scale and having a type D personality were correlated with the BODE index score. These results suggest that it is important for patients with COPD to be examined by a psychiatrist..

Fatigue, Depression, and Anxiety in Patients with COPD, Asthma and Asthma-COPD Overlap

INTRODUCTION

Asthma and COPD are extremely common respiratory diseases that have a serious impact on people's lives around the world. A disease characterized by symptoms characteristic for asthma and COPD is called asthma-COPD overlap (ACO). Fatigue and certain psychological disorders such as anxiety and depression are important comorbidities in these diseases. The purpose of this study was to assess the prevalence of fatigue, anxiety, and depression in patients with asthma, COPD, and ACO and to also consider their mutual correlations.

MATERIAL AND METHODS

A total of 325 patients were enrolled in the study. There were 159 women and 166 men and their mean age was 63. Two standardized questionnaires were used: the Modified Fatigue Impact Scale (MFIS) and the Hospital Anxiety and Depression Scale (HADS).

RESULTS

The mean total MFIS score for all patients was 33.03. Patients with asthma generally scored lower than patients with COPD and ACO. There were no statistical differences in the HADS for anxiety between the groups, although around half of the patients registered a score indicating some level of disorder. Patients with COPD and ACO were proven to suffer more from depression than patients with asthma. The HADS and MFIS scores were found to correlate significantly and positively.

CONCLUSIONS

Our study showed that patients with COPD, asthma, and ACO generally suffered from an increased level of fatigue and depression. Anxiety was high in all groups, but it was at a similar level for patients suffering from each of the three diseases under consideration. It is important to treat the physical symptoms as well as the psychological disorders since they greatly impact on the patient outcomes.

Frequent User mit Angststörung in der Berliner Notfallrettung: Analyse von Notrufverhalten, Diagnosegruppe und urbaner Verteilung

Einleitung Patienten mit Angststörung machen einen wesentlichen Anteil derjenigen Anrufer aus, die den Rettungsdienst in Anspruch nehmen. Es ist davon auszugehen, dass viele dieser Patienten als Frequent User wiederholt den Rettungsdienst alarmieren.

Methodik Als Frequent User mit Angststörung wurden diejenigen Patienten definiert, bei denen im Einsatzprotokoll die Kombination aus der (Verdachts-)Diagnose „Psychiatrischer Notfall“ sowie dem psychiatrischen Befund „ängstlich“ dokumentiert wurde und es im betrachteten Zeitraum (01.1.2020 bis 31.5.2021) zu mindestens 2 Einsätzen der Notfallrettung kam (n = 74).

Ergebnisse Die Alarmierung erfolgte in 31% zum psychiatrischen Notfall, aber auch zu Herzbeschwerden, Atembeschwerden oder Brustschmerzen. Bei 56,4% der Einsätze wurde als Hauptdiagnose eine psychiatrische Erkrankung angegeben, bei 43,6% eine sonstige Erkrankung. Ein Zusammenhang zwischen der Einsatzhäufigkeit und dem Patientenalter oder dem Wochentag bestand nicht. Im Stadtgebiet kam es zwar in einzelnen Bereichen mit Status-Index 4 (sehr niedriger sozialer Status) zu vermehrten Einsätzen, insgesamt zeigte sich jedoch eine gleichmäßige Verteilung im Stadtgebiet.

Schlussfolgerung Der wiederholte Transport in ein Krankenhaus kann bei Frequent Usern mit Angststörung einen erneuten Notruf nach sich ziehen. Ein Case Management könnte dazu beitragen, die Einsatzzahlen zu reduzieren und Frequent User mit Angststörung an geeignete Versorgungsformen anzubinden.

Flourishing despite Chronic Obstructive Pulmonary Disease (COPD): Findings from a Nationally Representative Survey of Canadians Aged 50 and Older

Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of mortality and is often associated with serious disability and depression. Little is known about the characteristics of those who are in complete mental health (CMH) despite having COPD. This study’s objectives are to: (1) estimate the prevalence and odds of absence of psychiatric disorders (APD) and CMH among older adults that reported having COPD, compared to their peers that did not; (2) identify factors associated with APD and with CMH. Bivariate and logistic regression analyses were conducted using the nationally representative Canadian Community Health Survey—Mental Health. The results indicate that there was a significantly (p < 0.001) lower prevalence of APD (86.7% vs. 95.0%) and CMH (66.7% vs. 77.0%) among older adults aged 50+ with COPD (n = 703) compared to those without COPD (n = 10,189). Half of the sample was female (50.5%) and the majority of whom were under age 70 (62.5%). Factors significantly (p < 0.05) associated with higher odds of APD and of CMH among older adults with COPD include being married, having a confidant, being physically active, and having no lifetime history of major depressive disorder or generalized anxiety disorder. For every additional adverse childhood experience, the odds of APD declined by 31%. The majority of those with COPD are mentally flourishing despite having this disabling and life-threatening disorder. These findings underline the importance of targeted interventions and outreach to those most vulnerable to poorer mental health outcomes including the socially isolated.

Development and validation of a risk prediction model for anxiety or depression among patients with chronic obstructive pulmonary disease between 2018 and 2020

Anxiety and depression are important risk factors for chronic obstructive pulmonary disease (COPD). The aim of this study was to develop a prediction model to predict anxiety or depression in COPD patients. The retrospective study was conducted in COPD patients receiving stable treatment between 2018 and 2020 to develop prediction model. The variables, were readily available in clinical practice, were analysed. After data preprocessing, model training and performance evaluation were performed. Validity of the prediction model was verified in 3 comparative model training. Between 2018 and 2020, 375 eligible patients were analysed. Thirteen variables were included into the final model: gender, age, marital status, education level, long-term residence, per capita annual household income, payment method of medical expenses, direct economic costs of treating COPD in the past year, smoking, COPD progression, number of acute exacerbation of COPD in the last year, regular treatment with inhalants and family oxygen therapy. Risk score threshold in each sample in the training set was 1.414. The area under the curve value was respectively 0.763 and 0.702 in the training set and test set, which were higher than three comparative models. The simple prediction model to predict anxiety or depression in patients with COPD has been developed. Based on 13 available data in clinical indicators, the model may serve as an instrument for clinical decision-making for COPD patients who may have anxiety or depression.Key messagesThirteen variables were included into the prediction model.The AUC value was, respectively, 0.763 and 0.702 in the training set and test set, which were higher than three comparative models.The simple prediction model to predict anxiety or depression in patients with COPD has been developed.

National Trends in Prevalence of Depression in Men and Women with Chronic Obstructive Pulmonary Disease Hospitalized in Spain, 2016–2020

(1) Background: To describe trends in the prevalence of depression in men and women with COPD hospitalized in Spain (2016–2020). (2) Methods: We used a nationwide discharge database to select all patients ≥35 years with COPD. (3) Results: The prevalence of depression was 3.54-times higher in women with COPD than in men (OR 3.54; 95%CI 3.48–3.6). It decreased significantly between 2016 and 2020, although the reduction was only significant in women (12.27% in 2016 vs. 10.56% in 2020). Older age, comorbidity and the most recent years of hospital admission were associated with lower prevalence of depression in both men and women, while obesity, obstructive sleep apnea (OSA) and use of oxygen prior to admission were risk factors. In-hospital mortality (IHM) increased significantly over time. Older age, comorbidity, the use of oxygen prior to admission and having been hospitalized in 2020 increased the risk of IHM. Female sex was associated with a lower IHM in patients with depression and COPD. (4) Conclusions: The prevalence of depression has decreased over time in women with COPD while it has not changed significantly in men with this disease. IHM increased over time both in men and women with COPD and depression, with higher prevalence in the former.

Dancing for Health and Wellbeing: A Feasibility Study of Examining Health Impacts of Online Dancing among Pulmonary Fibrosis Patients

BACKGROUND

Physical activity (PA) is recommended in the management of patients with pulmonary fibrosis (PF) to improve health outcomes. Dance is one such form of PA which is meaningful, valuable, enjoyable and has demonstrated positive physical and mental health effects.

METHODS

With pre-post design, 16 patients, members of the Irish Lung Fibrosis Association, were enrolled in this study. Once weekly, 75-min dance sessions were delivered for eight weeks via Zoom by an experienced choreographer. Participants completed Chronic Respiratory Questionnaire Self-Administered Standardised Format (CRQ-SAS) and European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L) to assess self-rated quality of life. A paired-sample t-test was employed to assess the mean differences between the pre-and post-intervention scores.

RESULTS

Most patients (78.57%) were aged over 60 years; with 71.43% diagnosed with pulmonary fibrosis more than 3 years ago. We performed an analysis of 10/16 participants who completed the intervention (5 males, 5 females). On CRQ-SAS scale we found, (a) dyspnoea-small to moderate magnitude improvement of 0.5-1.0 among 50%, (b) fatigue-small to moderate magnitude improvement of 0.5-1.0 among 40%, (c) emotional function-small to high magnitude improvement of 0.5-2.0 among 50%, (d) mastery-small magnitude improvement of 0.5 among 20%. Participants reported their health moderate to best on Visual Analogue Scale of EQ-5D-3L which improved by 1-3 scale among 40%. Mental health improved as percentage of not feeling anxious or depressed rose post event from 42.86% to 72.73%.

CONCLUSION

Our findings demonstrate that a virtual dance intervention is acceptable, enjoyable and feasible for improving health outcomes among PF patients. More organised and continuous events in future may reveal cost-benefit ratio and impact on health outcomes.

Disability Retirement After First Admission with Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Danish Nationwide Registry Cohort Study Using a Retrospective Follow-Up Design

Introduction

Many chronic obstructive pulmonary disease (COPD) patients below retirement age are outside the workforce. The existing knowledge about association between acute exacerbation of COPD (AECOPD) and disability retirement is limited.

Aim

The aim of this study is to explore disability retirement in COPD patients 3 years following first-ever AECOPD.

Methods

This retrospective registry-based follow-up cohort study design is based on nationwide Danish registry data. Patients admitted to the hospital for the first time between 1999 and 2017 with AECOPD and age between 35 and 59 years, active in the workforce, were included in the study. Socio-demographics, comorbidities and inhaled medication use were explored. COPD patients’ hazard ratio of disability retirement during 3-year follow-up was calculated. Cox regression was used to examine the effects of covariates on disability retirement.

Results

A total of 4032 patients were included in the study. During follow-up, 17.2% (692/4032) experienced disability retirement from the workforce. Factors associated with disability retirement were expressed as hazard ratio (95% confidence intervals): Higher age (ref. age 46–50: Age 51–55, 1.42, (1.12–1.81); age 56–59, 1.37 (1.08–1.74)); living alone (1.34 (1.14–1.56)); number of comorbidities for 1, 2, and 3 comorbidities (1.36 (1.14–1.62), 1.57 (1.19–2.07), 1.77 (1.20–2.60)); emphysema (2.01 (1.44–2.79)); depression (1.60 (1.12–2.28)); cardiac comorbidity (1.38 (1.07–1.78)); triple inhalation therapy (2.76 (2.20–3.47)); ICS + LAMA or ICS + LABA treatment (1.82 (1.48–2.23)); and ICS treatment (1.49 (1.17–1.90)). Higher educational level was associated with a significantly reduced risk of disability retirement, medium, short higher and long higher educational level, relative to low education level (0.78 (0.67–0.91), 0.63 (0.48–0.83) and 0.27 (0.12–0.60)).

Conclusion

Patients vulnerable to disability retirement are patients with markers of severe COPD, comorbidities, and social vulnerability.
