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.

The bidirectional relationship between activities of daily living and frailty during short-and long-term follow-up period among the middle-aged and older population: findings from the Chinese nationwide cohort study. Front Public Health 2024; 12:1382384. [PMID: 38746004 PMCID: PMC11091387 DOI: 10.3389/fpubh.2024.1382384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 04/12/2024] [Indexed: 05/16/2024] Open
Abstract
Objective Frailty and activities of daily living (ADL) disability are common conditions among older population. Studies on the bidirectional relationship between frailty and ADL are limited. The current study examined the cross-sectional and longitudinal associations between frailty and ADL in middle-aged and older Chinese individuals. Methods The data was collected through the China Health and Retirement Longitudinal Study (CHARLS), conducted in 2011, 2013, and 2015, encompassing 17,284 individuals aged ≥45 years. We excluded individuals without follow-up data. 2,631 participants finished the baseline survey. The definition of ADL disability encompasses difficulty in engaging in either basic activities of daily living (BADL) or instrumental activities of daily living (IADL). Frailty was assessed according to the Fried criteria. Logistic regression was utilized to examine odds ratios (ORs) and 95% confidence intervals (CIs) for assessing the cross-sectional relationships between ADL with frailty at baseline. The prediction effects were explored using Cox proportional hazards analysis, testing hazard ratios (HRs) and 95%CIs. Results In cross-sectional analysis, BADL [OR = 6.660 (4.519-9.815)], IADL [OR = 5.950 (4.490-7.866)], and ADL [OR = 5.658 (4.278-7.483)] exhibited significant associations with frailty; frailty demonstrated significant associations with BADL [OR = 6.741 (4.574-9.933)], IADL [OR = 6.042 (4.555-8.016)] and ADL [OR = 5.735 (4.333-7.591)]. In longitudinal analysis, IADL and ADL were significantly associated with frailty in participants without baseline frailty in the short-term period [IADL: HR = 1.971 (1.150-3.379), ADL: HR = 1.920 (1.146-3.215)], IADL exhibited a significant association with frailty in the long-term period [HR = 2.056 (1.085-3.895)]. There was no significant link observed between frailty and an elevated risk of disability onset in BADL, IADL and ADL during the short-term period. When considering the long-term perspective, frailty exhibited a significant association with an elevated risk of disability onset in BADL [HR= 1.820 (1.126-2.939)] and IADL [HR = 1.724 (1.103-2.694)]. Conclusion In middle-aged and older adults, ADL and IADL disability predicted frailty after 2-year follow-up, IADL disability predicted frailty after 4-year follow-up. Moreover, frailty did not predict BADL, IADL and ADL disability after 2-year follow-up. However, frailty predicted BADL and IADL disability after 4-year follow-up.

Abstract
BACKGROUND Depression in middle-aged and elderly individuals is multifaceted and heterogeneous, linked to biological age (BA) based on aging-related biomarkers. However, due to confounding with chronological age and the absence of subgroup analysis and causal reasoning, the association between BA and depressive symptoms (DS) might be unstable and requires further investigation. METHODS We utilized data from the China Health and Retirement Longitudinal Study (N = 9478) to perform association analysis, causal inference, and subgroup analysis. BA acceleration (BAA) was derived using machine learning and adjusted for chronological age. A generalized linear mixed-effects model (GLMM) tree algorithm was employed to identify subgroups. The causal reasoning frame included propensity score matching and fast large-scale almost matching exactly. RESULTS In the longitudinal analysis, BAA exhibited a consistent and significant positive association with DS, even after controlling for demographic characteristics, lifestyle factors, health status, and physical functions. This association remained unchanged within the causal framework. GLMM tree analysis identified three partitioning variables (sex, satisfaction, and BMI) and five subgroups. Further subgroup analysis revealed that BAA exerted the strongest effect on DS among women with less satisfying lives. LIMITATIONS Depressive symptoms were evaluated through scale measurements rather than clinical diagnosis. The sample was derived from the general population, not the clinically depressed population. CONCLUSIONS This study provided the first longitudinal evidence that biological age acceleration increases depressive symptoms under causal reasoning and subgroup analysis, particularly among less satisfied women. And the association between BAA and DS was independent of known risk factors.

Abstract
PURPOSE Patients undergoing long-term oxygen therapy (LTOT) are predisposed to progressive cognitive decline; however, the association between cognitive decline progression and activities of daily living (ADL) decline has not been described. We aimed to describe the association between cognitive decline progression and ADL decline in patients undergoing LTOT. MATERIALS AND METHODS In this prospective observational pilot study, data were collected at baseline and 1-year following the ambulatory recruitment of patients in the Department of Respiratory Medicine at the National Hospital Organization Nishiniigata Chuo Hospital. We recruited 96 patients with chronic respiratory disease undergoing LTOT, and 55 patients who completed a 1-year follow-up were finally included. RESULTS Multivariate logistic regression analysis revealed that Montreal Cognitive Assessment score reduction (a measure of cognitive decline) was associated with Barthel index score reduction (a measure of ADL) at 1-year follow-up (odds ratio: 3.98; 95% confidence interval: 1.16 - 13.69; p = 0.02). CONCLUSION A progression of cognitive decline in patients undergoing LTOT may affect ADL decline. An early detection of cognitive decline in patients undergoing LTOT is essential for ADL maintenance in rehabilitation practice.IMPLICATIONS FOR REHABILITATIONPatients undergoing long-term oxygen therapy (LTOT) present with progressive cognitive decline.Cognitive decline progression is associated with a decline in activities of daily living in patients undergoing LTOT.A periodic cognitive assessment is important in rehabilitation practice for the early detection of progressive cognitive decline in patients undergoing LTOT.

Abstract
OBJECTIVES Frailty is associated with a range of poor post-stroke outcomes. There is still a lack of comprehensive understanding of the temporal relationship between pre-stroke frailty status and other related factors with functional recovery after stroke. This study aims to evaluate pre-stroke frailty status and health-related factors associated with functional independence among community-dwelling Chinese older adults. MATERIALS AND METHODS The dataset based on the China Health and Retirement Longitudinal Study (CHARLS) conducted in 28 provinces across China was used. The pre-stroke frailty status was assessed using the Physical Frailty Phenotype (PFP) scale with the 2015 wave data. The PFP scale consisted of five criteria with a total score of 5, and categorized into non-frail (0 point), prefrail (1 and 2 points), and frail (3 or more points). Covariates included demographic factors (age, sex, marital status, residence, and education level) and health-related variables (comorbidities, self-reported health status and cognition). Activities of daily living (ADL) and instrumental activities of daily living (IADL) were assessed as the functional outcomes, with difficulties in at least one of the 6 ADL items and 5 IADL items defined as ADL/IADL limitation respectively. A logistic regression model was used to estimate the associations. RESULTS A total of 666 participants who were newly diagnosed with stroke during the 2018 wave were included. 234 (35.1%) participants were classified as non-frail, 380 (57.1%) participants were classified as prefrail, and 52 (7.8%) participants were classified as frail. Pre-stroke frailty was significantly associated with ADL and IADL limitations post stroke. Additional significant variables with ADL limitation were age, female and more comorbidities. Additional significant variables with IADL limitation were age, female, married or cohabitating, more comorbidities and pre-stroke lower global cognitive score. CONCLUSION Frailty status was associated with ADL and IADL limitations after stroke. A more comprehensive assessment of frailty in older people may help to identify those with most significant risk for declining functional capacities after stroke and to develop appropriate intervention strategies.

Abstract
The purpose of this study was to investigate the relationship between cognitive function and depressive symptoms among Chinese adults aged 40 years and above, as well as the series of multiple mediating effects of Instrument Activities of Daily Living disability and life satisfaction on this relationship. The data was obtained from the China Health and Retirement Longitudinal Study (CHARLS, 2013-2018), including 6466 adults aged 40 years and above. The mean age of the adults was 57.7 ± 8.5. The SPSS PROCESS macro program was conducted to examine the mediating effects. The results indicated that there was a significant association between cognitive function and depressive symptoms five years later (B = -0.1500, 95%CI: -0.1839, -0.1161), which could also be demonstrated through three mediation pathways: (1) the mediating pathway through IADL disability (B = -0.0247, 95%CI: -0.0332, -0.0171); (2) the mediating pathway through life satisfaction (B = 0.0046, 95%CI: 0.0000, 0.0094); and (3) the chain mediation pathway through IADL disability and life satisfaction (B = -0.0012, 95%CI: -0.0020, -0.0003). Both IADL disability and life satisfaction have been proven to be crucial mediators for the relationship between cognitive function and depressive symptoms five years later. It is necessary to improve individuals' cognitive function and reduce the negative impact of disability on them, which is important to enhance their life satisfaction and prevent depressive symptoms.

Abstract
Chronic obstructive pulmonary disease (COPD) is the third cause of death worldwide, presenting poor long-term outcomes and chronic disability. COPD is a condition with a wide spectrum of clinical presentations because its pathophysiological determinants relate to tobacco smoke, genetic factors, alteration of several metabolic pathways, and oxidative stress. As a consequence, patients present different phenotypes even with comparable degrees of airflow limitation. Because of the increasing social and economic costs of COPD, a growing attention is currently payed to "omics" techniques for more personalized treatments and patient-tailored rehabilitation programs. In this regard, the systematic investigation of the metabolome (i.e., the whole set of endogenous molecules) in biomatrices, namely metabolomics, has become indispensable for phenotyping respiratory diseases. The metabolomic profiling of biological samples contains the small molecules produced during biological processes and their identification and quantification help in the diagnosis, comprehension of disease outcome and treatment response. Exhaled breath condensate (EBC), plasma and serum are biofluids readily available, with negligible invasiveness, and, therefore, suitable for metabolomics investigations. In this paper, we describe the latest advances on metabolomic profiling of EBC, plasma and serum in COPD patients.

Abstract
Chronic obstructive pulmonary disease (COPD) is an increasing cause of global morbidity and mortality, with poor long-term outcomes and chronic disability. COPD is a condition with a wide spectrum of clinical presentations, with different phenotypes being identified even among patients with comparable degrees of airflow limitation. Considering the burden of COPD in terms of social and economic costs, in recent years a growing attention has been given to the need of more personalized approaches and patient-tailored rehabilitation programs. In this regard, the systematic analysis of metabolites in biological matrices, namely metabolomics, may become an essential tool in phenotyping diseases. Through the identification and quantification of the small molecules produced during biological processes, metabolomic profiling of biological samples has thus been proposed as an opportunity to identify novel biomarkers of disease outcome and treatment response. Exhaled breath condensate (EBC) and plasma/serum are fluid pools, which can be easily extracted and analyzed. In this review, we discuss the potential clinical applications of the metabolomic profiling of EBC and plasma/serum in COPD.

Abstract
OBJECTIVES This study aimed to examine to what extent depressive symptoms mediated and moderated the association between cognitive function and activities of daily living (ADL) disability in older adults. METHODS In older participants from the China Health and Longitudinal Retirement Survey (CHARLS), structural equation modeling and multiple regression were performed to examine the mediating and moderating role of depressive symptoms (measured by the 10-item Center for Epidemiologic Studies Depression Scale) in the association between baseline cognitive function (episodic memory, attention, orientation to time, and visuospatial ability) and endpoint disability in basic ADL (BADL) or instrumental ADL (IADL). RESULTS Over a 2-year follow-up, among 1677 participants (67.5 ± 6.0 years old) free of BADL disability and 1194 participants (66.9 ± 5.6 years old) free of IADL disability, 8.3% and 22.9% developed BADL disability and IADL disability, respectively. Good baseline cognitive performance was significantly associated with the reduced incidence of BADL/IADL disability. The indirect effects of baseline depressive symptoms explained 16.9% and 14.5% of the total effect between cognition and BADL and IADL dependency, respectively. The Johnson-Neyman technique identified a threshold of 7.88 for endpoint depressive symptoms, beyond which the protective effect of baseline cognitive function on BADL emerged. CONCLUSIONS In older adults, good cognitive function reduces the risk of BADL/IADL disability. Depressive symptoms downregulate the protective effect of cognitive function on BADL/IADL over time. Intervention techniques focusing on the simultaneous improvement of cognitive dimensions and depression help improve ADL difficulty and prevent disability in older adults.

Abstract
OBJECTIVE Cognitive function and depression impact critically the daily functioning of menopausal women. This study aimed to explore the mediating and moderating effects of depressive symptoms on the association between cognitive function and activities of daily living (ADL) difficulty in postmenopausal women. METHODS A total of 2,596 postmenopausal women from the China Health and Retirement Longitudinal Study completed the Chinese version of the Mini-Mental State Examination, basic ADL (BADL) and instrumental ADL (IADL) scales, and 10-item Short-Form Center for Epidemiological Studies Depression. We constructed structural equation modeling to examine the association between cognitive function, depressive symptoms, and BADL/IADL difficulty. RESULTS The prevalence of BADL/IADL difficulty in postmenopausal women was 22.5% and 31.5%, respectively. After adjustments for demographic and health-related covariates, cognitive decline (contributed by four cognitive dimensions with different weights) was significantly associated with BADL/IADL difficulty (contributed by six-item daily activities with different weights). Depressive symptoms mediated and explained 28.8% and 23.2% of cognitive function associations with BADL and IADL difficulty, respectively. The Johnson-Neyman technique identified a threshold of eight and four for depressive symptoms, beyond which the protective effect of cognitive function on BADL and IADL emerged. CONCLUSIONS Depressive symptoms mediated and moderated the association between cognition and BADL/IADL difficulty in postmenopausal women. Compared with BADL, IADL may be more sensitive to changes in cognitive function. More strength should be put on developing comprehensive intervention techniques focusing on simultaneous intervention of multidimensional cognitive function and depression to maintain and improve the quality of life of postmenopausal women.
