Interactions between Cognitive, Affective, and Respiratory Profiles in Chronic Respiratory Disorders: A Cluster Analysis Approach. Diagnostics (Basel) 2024; 14:1153. [PMID: 38893678 PMCID: PMC11171769 DOI: 10.3390/diagnostics14111153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2024] [Revised: 05/25/2024] [Accepted: 05/28/2024] [Indexed: 06/21/2024] Open
Abstract
This study conducted at Leamna Pulmonology Hospital investigated the interrelations among cognitive, affective, and respiratory variables within a cohort of 100 patients diagnosed with chronic respiratory conditions, utilizing sophisticated machine learning-based clustering techniques. Spanning from October 2022 to February 2023, hospitalized individuals confirmed to have asthma or COPD underwent extensive evaluations using standardized instruments such as the mMRC scale, the CAT test, and spirometry. Complementary cognitive and affective assessments were performed employing the MMSE, MoCA, and the Hamilton Anxiety and Depression Scale, furnishing a holistic view of patient health statuses. The analysis delineated three distinct clusters: Moderate Cognitive Respiratory, Severe Cognitive Respiratory, and Stable Cognitive Respiratory, each characterized by unique profiles that underscore the necessity for tailored therapeutic strategies. These clusters exhibited significant correlations between the severity of respiratory symptoms and their effects on cognitive and affective conditions. The results highlight the benefits of an integrated treatment approach for COPD and asthma, which is personalized based on the intricate patterns identified through clustering. Such a strategy promises to enhance the management of these diseases, potentially elevating the quality of life and everyday functionality of the patients. These findings advocate for treatment customization according to the specific interplays among cognitive, affective, and respiratory dimensions, presenting substantial prospects for clinical advancement and pioneering new avenues for research in the domain of chronic respiratory disease management.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory disorder often accompanied by comorbidities. Although the past few years have witnessed significant scientific progress, the potential relationship between COPD and mental illness remains a subject of debate. Materials and Methods We retrieved COPD data from the genome-wide association studies (GWAS) directory and data on mental illnesses, including Alzheimer's disease, schizophrenia, panic disorder, attention deficit hyperactivity disorder (ADHD), bipolar disorder, major depressive disorder, multiple disabilities, obsessive-compulsive disorder, post-traumatic stress disorder, and schizophrenia, from the Psychiatric Genomics Consortium. A two-sample Mendelian randomization (MR) approach was applied to explore the association between COPD and mental illnesses, with subgroup analyses based on smoking history. Results Our two-sample MR analysis revealed no causal link between overall COPD and the development of common psychiatric disorders. Subgroup analyses based on smoking history showed no causal association between never-smokers with COPD and the occurrence of psychiatric disorders. However, ever-smokers with COPD were associated with a significantly increased risk of ADHD (OR: 2.303, 95% CI: 1.558-3.403, P = 0.001) and a modestly reduced risk of Alzheimer's disease (OR: 0.994, 95% CI: 0.988-0.999, P = 0.034). Conclusion COPD patients with a history of smoking face a higher risk of developing ADHD but may experience a slight reduction in the risk of Alzheimer's disease. Conversely, there was no observed causal association between COPD and psychiatric disorders among patients who never smoked.

Abstract
Purpose The rural-urban gap in sociodemographic, lifestyle, and disease-related characteristics among COPD patients is prevalent. These differences may influence the prevalence of mild cognitive impairment (MCI). This study aimed to compare the prevalence and determinants of MCI between rural and urban areas among COPD patients. Patients and Methods The cross-sectional study sample comprised 372 COPD patients from China. We evaluated the cognitive function and lung function, collected sociodemographic, lifestyle, and disease-related information, to compare the prevalence of MCI in rural and urban areas. Using multivariate regression analysis to examine the effects of variables to MCI. Results The prevalence of MCI in rural areas was higher than that in urban areas (65.4% vs 47.9%, P=0.001). The prevalence in farm laborers was almost twice as high as that of non-farm laborers in urban areas (82.6% vs 43.1%), but no significant difference in rural areas (P=0.066). However, the data were lower in subjects who insisted on long-term home oxygen therapy (39.7%, CI:27.8-51.6, P<0.001), and who with higher monthly household income (49.6%, CI:40.2-58.9) in rural areas, but no significant difference in urban areas (P=0.985 and 0.502). Multivariate logistic regression analysis indicated that participants aged 71 years and above, former smokers were at a high risk of MCI in both urban and rural areas. However, participants who slept for 6-8 hours a day, shopping frequently, or exercised for more than 2 hours a day had a lower risk of MCI in urban areas. But rural participants who insisted on long-term home oxygen therapy had a lower probability of developing MCI. Conclusion This study revealed that there were significant differences in MCI among COPD patients in rural and urban areas, especially in exercise, sleeping, shopping, and long-term home oxygen therapy. Medical staff should give health guidance according to the actual situation of patients with COPD.

Abstract
OBJECTIVES Many studies document cognitive decline following specific types of acute illness hospitalizations (AIH) such as surgery, critical care, or those complicated by delirium. However, cognitive decline may be a complication following all types of AIH. This systematic review will summarize longitudinal observational studies documenting cognitive changes following AIH in the majority admitted population and conduct meta-analysis (MA) to assess the quantitative effect of AIH on post-hospitalization cognitive decline (PHCD). METHODS We followed Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Selection criteria were defined to identify studies of older age adults exposed to AIH with cognitive measures. 6566 titles were screened. 46 reports were reviewed qualitatively, of which seven contributed data to the MA. Risk of bias was assessed using the Newcastle-Ottawa Scale. RESULTS The qualitative review suggested increased cognitive decline following AIH, but several reports were particularly vulnerable to bias. Domain-specific outcomes following AIH included declines in memory and processing speed. Increasing age and the severity of illness were the most consistent risk factors for PHCD. PHCD was supported by MA of seven eligible studies with 41,453 participants (Cohen's d = -0.25, 95% CI [-0.02, -0.49] I2 35%). CONCLUSIONS There is preliminary evidence that AIH exposure accelerates or triggers cognitive decline in the elderly patient. PHCD reported in specific contexts could be subsets of a larger phenomenon and caused by overlapping mechanisms. Future research must clarify the trajectory, clinical significance, and etiology of PHCD: a priority in the face of an aging population with increasing rates of both cognitive impairment and hospitalization.

Abstract
PURPOSE OF REVIEW Chronic obstructive pulmonary disease (COPD) imposes a large burden on the global population and even more so for the elderly who face significant obstacles in the diagnosis, management, and psychosocial effects of the disease. This review describes the current challenges and key points in the management of COPD in the elderly. RECENT FINDINGS Lower limit rather than fixed cut off of the FEV1/FVC ratio can improve the diagnosis and better predict COPD mortality. High relative to standard dose influenza vaccination reduces confirmed cases of influenza overall and reduces hospitalizations in older nursing home residents. Simple interventions that include electronic health record tracking can significantly improve vaccination rates. Although many inhaler and nebulized medications are available for the elderly, the final regimen is usually determined by a combination of expense, issues with proper device use (from difficulty with coordination, hand grip, inspiratory flows or cognitive function) and the side effect profile. Fortunately, the switch to cheaper or better covered alternatives can be well tolerated with improvement in adherence and exacerbations of COPD. Finally, caution should be made against ageism, which may be a factor in the recommendation of rehabilitation or palliative care in the elderly COPD patient, as both are underused despite evidence of benefit. SUMMARY Although care for the elderly COPD patient can be difficult, we summarize key points that the physician should be cognizant of to provide comprehensive care.

Long-term intradialytic hybrid exercise training on fatigue symptoms in patients receiving hemodialysis therapy. Int Urol Nephrol 2021; 53:771-784. [PMID: 33387217 DOI: 10.1007/s11255-020-02711-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 11/04/2020] [Indexed: 01/12/2023]
Abstract
PURPOSE Hemodialysis (HD) patients suffer from generalized weakness, exercise intolerance and muscle atrophy, all leading to generalized fatigue and lack of energy. HD patients spend at least 50% of their time in a functionally "switch off" mode with their fatigue sensations reaching a peak in the immediate hours after the dialysis session. The purpose of the current study was to assess the effectiveness of a nine-month hybrid intradialytic exercise program on fatigue symptoms occurring during and after hemodialysis session. METHODS Twenty stable hemodialysis patients were included in the study (59 ± 13.7 years; 16 males). All patients completed a 9-month supervised exercise training program composed of both aerobic cycling and resistance training during HD. Aspects related to physical and generalized fatigue were assessed via validated questionnaires, while physical performance was assessed by a battery of tests, before and after the intervention period. RESULTS Exercise capacity and physical performance were increased by an average of 65 and 40%, respectively. Patients reported feeling better during post-dialysis hours in question 1 (p = 0.000), question 3 (p = 0.009) and question 4 (p = 0.003) after the 9-month intervention. In addition, exercise training improved scores in cognitive function (p = 0.037), vitality (p = 0.05), depression (p = 0.000) and fatigue (p = 0.039). CONCLUSION The present study showed that a 9-month hybrid (aerobic + resistance) exercise training program improved symptoms of post-dialysis fatigue and overall general perception of fatigue. Hybrid exercise training is a safe and effective non-pharmacological approach to ameliorate fatigue symptoms in HD patients. TRIAL REGISTRATION NUMBER Trial registration number The study is registered at ClinicalTrials.gov (NCT01721551, 2012) as a clinical trial.

Abstract
Introduction: We evaluated risk factors and demographic characteristics of associated with mild cognitive impairment (MCI) in patients with COPD. Methods: 220 individuals with COPD enrolled in a cohort study designed to evaluate anxiety conducted at 16 clinical centers. Cognitive impairment was assessed with the Montreal Cognitive Assessment (MoCA), a cutoff score of <26 defined as MCI. Data were collected including spirometry, 6-minute walk test, symptom burden by COPD Assessment Test and dyspnea by Modified Medical Research Council, anxiety measured by Anxiety Inventory of Respiratory Disease, Generalized Anxiety Disorder-7 and Hospital Anxiety Depression Scale, depression by Patient Health Questionnaire-9 and health status by Patient Reported Outcomes Measurement Information System and sleep quality by the Pittsburg Sleep Quality Index. Results: The median age was 65 years and 54% of participants were male. 119(54%) of participants had MCI as classified by MoCA. In multivariable logistic regression, higher odds ratios (OR) (95% confidence interval) for MCI (MoCA) <26 were associated with increased years of age, 1.06 (1.02 -1-09, p<0.003); African-American race, 3.68(1.67-8.11, p<0.001); persistent phlegm, 2 (1.12-3.57, p<0.01) and sleep disturbance, 1.04(1.01-1.08, p<0.01). Conclusions: COPD patients commonly screen positive for MCI. Characteristics associated with MCI included age, African-American race, sleep disturbance and persistent phlegm.

Abstract
Purpose Prior studies have indicated that patients with chronic obstructive pulmonary disease (COPD) exhibit significant cognitive defects on neuropsychological testing. Obstructive sleep apnea (OSA) is common in patients with COPD and is associated with reduced cognitive function; however, the combined impact of these two conditions on cognitive function is unknown. The aim of the study was to investigate the impact of OSA on cognitive impairment in patients with COPD. Methods Sixty-five stable COPD patients aged over 60 years underwent overnight polysomnography (PSG). Global cognitive functions were evaluated using the Mini-Mental State Examination (MMSE). Results Compared to patients with COPD alone, patients with both COPD and OSA performed worse on the MMSE (25.5±2.9 vs 23.5±3.2; p=0.01) and were more likely to be at risk for developing dementia based on the MMSE score (MMSE≤24) (31% vs 66%; p<0.01), independent of key demographic, educational and medical variables known to affect cognitive function in COPD. COPD patients with an apnea hypopnea index (AHI) of ≥30 events/h had lower MMSE scores than those with an AHI of <15 events/h. In addition to age and education level, the severity of nocturnal intermittent hypoxia is an independent predictor of the risk of dementia in patients with COPD (OR=1.24, 95% CI 1.04-1.48, p = 0.02). Conclusion The current findings indicate that patients with COPD with comorbid OSA may be at greater risk for global cognitive impairment relative to patients with COPD alone. The mechanisms underlying the exaggerated cognitive dysfunction seem to be related to intermittent hypoxia. Further work is needed to understand the impact of OSA on the specific domains of cognitive impairment and the therapeutic implications of OSA in COPD.

Abstract
Abstract
The American Occupational Therapy Association (AOTA) asserts that occupational therapists and occupational therapy assistants, through the use of occupations and activities, facilitate clients’ cognitive functioning to enhance occupational performance, self-efficacy, participation, and perceived quality of life. Cognitive processes are integral to effective performance across the broad range of daily occupations such as work, educational pursuits, home management, and play and leisure. Cognition plays an integral role in human development and in the ability to learn, retain, and use new information to enable occupational performance across the lifespan.
This statement defines the role of occupational therapy in evaluating and addressing cognitive functioning to help clients maintain and improve occupational performance. The intended primary audience is practitioners1 within the profession of occupational therapy. The statement also may be used to inform recipients of occupational therapy services, practitioners in other disciplines, and the wider community regarding occupational therapy theory and methods and to articulate the expertise of occupational therapy practitioners in addressing cognition and challenges in adapting to cognitive dysfunction.

Abstract
BACKGROUND Attention difficulties are often reported by patients with chronic obstructive pulmonary disease (COPD); however, limited research exists using objective tests designed specifically to measure attention in this population. This study aimed to (1) identify specific attention deficits in COPD and (2) determine which demographic/clinical characteristics are associated with reduced attention. METHODS Eighty-four former smokers (53 COPD, 31 no COPD) completed questionnaires, pulmonary function testing, and the Conner's Continuous Performance Test II (CPT-II). Participants with and without COPD were compared on CPT-II measures of inattention, impulsivity, and vigilance. CPT-II measures that differed significantly between the two groups were further examined using hierarchical regression modeling. Demographic/clinical characteristics were entered into models with attention as the dependent variable. RESULTS Participants with COPD performed worse than those without COPD on CPT measures of inattention and impulsivity (i.e., detectability [discrimination of target from non-target stimuli], perseverations [reaction time under 100 ms], omissions [target stimuli response failures], and commissions [responses to non-target stimuli]). More severe COPD (measured by greater airflow limitation) was associated with poorer ability to detect targets vs. foils and perseverative responding after adjusting for age and other covariates in the model. CONCLUSION Former smokers with COPD experience problems with attention that go beyond slowed processing speed, including aspects of inattention and impulsivity. Clinicians should be aware that greater airflow limitation and older age are associated with attention difficulties, as this may impact functioning.

Abstract
BACKGROUND Despite their poor prognosis, patients with severe chronic obstructive pulmonary disease (COPD) have little access to palliative care and tend to have a high rate of hospital and intensive care unit (ICU) admissions during their last year of life. OBJECTIVES To determine the feasibility of a home palliative care intervention during 1 year versus usual care, and the possible impact of this intervention on emergency, hospital and ICU admissions, survival, mood, and health-related quality of life (HRQL). METHODS Prospective controlled study of patients with severe COPD (GOLD stage III or IV) and long-term oxygen therapy and/or home noninvasive ventilation and/or one or more hospital admissions in the previous year for acute exacerbation, randomized to usual care versus usual care with add-on monthly intervention by palliative care specialists at home for 12 months. RESULTS Of 315 patients screened, 49 (15.5%) were randomized (26 to early palliative care; 23 to the control group); aged (mean ± SD) 71 ± 8 years; FEV1 was 37 ± 14% predicted; 88% with a COPD assessment test score > 10; 69% on long-term oxygen therapy or home noninvasive ventilation. The patients accepted the intervention and completed the assessment scales. After 1 year, there was no difference between groups in symptoms, HRQL and mood, and there was a nonsignificant trend for higher admission rates to hospital and emergency wards in the intervention group. CONCLUSION Although this pilot study was underpowered to formally exclude a benefit from palliative care in severe COPD, it raises several questions as to patient selection, reluctance to palliative care in this group, and modalities of future trials.

Abstract
We aimed to investigate (1) the relationship between cognitive impairment (CI) and
disease severity and (2) the potential differences in exercise performance, daily
activities, health status, and psychological well-being between patients with and without
CI. Clinically stable chronic obstructive pulmonary disease (COPD) patients, referred for
pulmonary rehabilitation, underwent a neuropsychological examination. Functional exercise
capacity (6-minute walk test [6MWT]), daily activities (Canadian Occupational Performance
Measure [COPM]), health status (COPD Assessment Test [CAT]) and St George’s Respiratory
Questionnaire-COPD specific [SGRQ-C]), and psychological well-being (Hospital Anxiety and
Depression Scale [HADS], Beck Depression Inventory [BDI], and Symptom Checklist 90
[SCL-90]) were compared between patients with and without CI. Of 183 COPD patients (mean
age 63.6 (9.4) years, FEV1 54.8 (23.0%) predicted), 76 (41.5%) patients had CI.
The prevalence was comparable across Global Initiative for Chronic Obstructive Lung
Disease (GOLD) grades 1–4 (44.8%, 40.0%, 41.0%, 43.5%, respectively, p =
0.97) and GOLD groups A–D (50.0%, 44.7%, 33.3%, 40.2%, respectively, p =
0.91). Patients with and without CI were comparable for demographics, smoking status,
FEV1% predicted, mMRC, 6MWT, COPM, CAT, HADS, BDI, and SCL-90 scores.
Clinical characteristics of COPD patients with and without CI are comparable. Assessment
of CI in COPD, thus, requires an active case-finding approach.

Abstract
RATIONALE Cognitive dysfunction has been demonstrated in chronic obstructive pulmonary disease (COPD), but studies are limited to cross-sectional analyses or incompletely characterized populations. OBJECTIVES We examined longitudinal changes in sensitive measures of executive function in a well-characterized population of patients with severe COPD. METHODS This study was performed on patients enrolled in the National Emphysema Treatment Trial. To assess executive function, we analyzed trail making (TM) A and B times at enrollment in the trial (2,128 patients), and at 12 (731 patients) and 24 months (593 patients) after enrollment, adjusted for surgery, marriage status, age, education, income, depression, PaO2, PaCO2, and smoking. Associations with survival and hospitalizations were examined using Cox regression and linear regression models. MEASUREMENTS AND MAIN RESULTS The average age of the patients was 66.4 years, and the average FEV1 was 23.9% predicted. At the time of enrolment, 38% had executive dysfunction. Compared with those who did not, these patients were older, less educated, had higher oxygen use, higher PaCO2, worse quality of life as measured by the St. George's Respiratory Quotient, reduced well-being, and lower social function. There was no significant change over 2 years in TM A or B times after adjustment for covariables. Changes in TM B times were modestly associated with survival, but changes in TM B-A times were not. Changes in TM scores were not associated with frequency of hospitalization. Lung function, PaO2, smoking, survival, and hospitalizations were not significantly different in those with executive dysfunction. CONCLUSIONS In this large population of patients with severe emphysema and heavy cigarette smoking exposure, there was no significant decline over 2 years in cognitive executive function as measured by TM tests. There was no association between executive function impairment and frequency of hospitalization, and there was a possible modest association with survival. It is plausible that cerebrovascular comorbidities explain previously described cognitive pathology in COPD.
