Assessing perceived participation among older adults total hip arthroplasty and total knee arthroplasty patients six months post-surgery: a cross-sectional study.

This research sought to assess the perceived levels of participation and autonomy in senior patients who had received total hip arthroplasty (THA) or total knee arthroplasty (TKA) in Hangzhou, China. Furthermore, the study aimed to identify the factors linked to these outcomes. This investigation will utilize a cross-sectional study design to assess perceived participation and autonomy among older adults total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients. The research was conducted in Hangzhou, China, at a tertiary hospital. Convenient sampling was utilized to select 139 patients who underwent THA or TKA between March 2022 and March 2023 and met the inclusion criteria at a tertiary hospital in Hangzhou. The Impact on Participation and Autonomy Questionnaire, Hip/Knee Injury and Osteoarthritis Outcome Score (HOOS/KOOS), 5-Item Geriatric Depression Scale, Multidimensional Scale of Perceived Social Support, and Elders Health Empowerment Scale were used to assess perceived participation, hip/knee-related symptoms and functional restrictions, depression symptoms, social support, and health empowerment. The mean score for perceived participation and autonomy was 22.554 (SD: 13.042). The mean scores for participation in indoor autonomy, outdoor autonomy, family roles, and social relations were 0.654 (SD: 0.608), 1.324 (SD: 0.792), 1.053 (SD: 0.657), and 0.664 (SD: 0.542), respectively. Negative correlations were observed between perceived participation/autonomy scores and HOOS/KOOS, social support, and health empowerment scores. Conversely, a positive correlation was found between perceived participation/autonomy scores and depression scores. The detrimental effect of HOOS/KOOS, social support, and health empowerment scores on perceived participation and autonomy was notable, while the impact of depressive symptoms was comparatively minor. Older Chinese patients, at first six months post THA/TKA surgery, reported higher levels of perceived participation compared to individuals with other conditions, such as stroke patients. Functional limitations resulting from hip/knee-related symptoms, as well as social support and health empowerment, emerged as significant influencing factors for perceived participation and autonomy. This research enhances our comprehension of the elements influencing perceived participation among older adults individuals who have undergone THA/TKA procedures.

Metabolomics and frailty: a "from bench to bedside" approach to atrial fibrillation in older patients

Abstract Background Atrial fibrillation (AF) is the most common sustained arrhythmia diagnosed at an advanced age. The most important complications of AF are stroke, heart failure and dementia. The pathophysiology of the arrhythmia is complex and multifaceted and several aspects are still not completely understood. Purpose Our project aimed at exploring the molecular characteristics of AF in older patients using an untargeted metabolomics approach, an analytical technique that provides an insight of the global metabolic profile at an individual level. As secondary endpoints, we evaluated the association between metabolomics and acylcarnitines, which are mediators of myocyte electrical instability, and difference in metabolomics profile between healthy controls (C) and AF patients (AF-P). Method We evaluated 50 consecutive older AF-P with persistent AF, waiting to be treated with elective electrical cardioversion of the arrhythmia, and 22 healthy controls (C). In all patients, the cardiological evaluation was integrated with tools of the Geriatric Multidimensional Assessment (GMA) to describe neurocognitive function (Mini-Mental State Examination, MMSE), depressive symptoms (15-item Geriatric Depression Scale, GDS), and physical performance (Short Physical Performance Battery, SPPB). Interleukin-6 (IL-6), a marker of low-grade inflammation, was measured with ELISA assays. Metabolomics analysis and acylcarnitine measurements were carried out using gas chromatography coupled with mass spectrometry (GC-MS). Results AF-P and C did not differ by age (76 ± 6 vs. 70 ± 14 years, p = 0.055); patients had a lower proportion of women (AF-P: 32% vs. C: 64%, p = 0.012). Cluster analysis applied to metabolomic data in all population identified two subset of subjects, characterized by a different body mass index (BMI; 23.57 vs. 32.53 Kg/m², p = 0.046). When studying only the AF-P group, the simultaneous presence of a higher CHA2DS2-VASc score (4.17 ± 1.32 vs. 2.88 ± 1.83, p = 0.007), a lower physical function (SPPB; 8.97± 2.22 vs. 10.75 ± 1.13, p = 0.009), and higher IL-6 levels (4.42 vs. 2.39 pg/mL, p = 0.002) described the cluster with a worse clinical phenotype and a specific metabolomics pattern. Furthermore, an association between IL-6 and medium- long-chain acylcarnitines emerged (acylcarnitine 12:1, β = 31.7 ± 9.4, R = 0.446, p = 0.001). Conclusions Present analysis demonstrated that a specific metabolomics profile was characteristic of older AF patients with a frail phenotype, identified by higher CHA2DS2-VASc score and IL-6 concentration, and lower physical performance. Future studies are needed to reveal the single molecular pathways responsible of these behaviour, potentially useful to guide a targeted therapy. Last, inflammation per se could contribute to electrical instability in AF, while body mass index, a surrogate measure of undernutrition, could identify different metabolic pathways in controls and in patients with the arrhythmia.Metabolomics by clinical phenotypes

44 Can Clinical Trial data Inform our Understanding of the role of Depressive Symptoms in Alzheimer's Disease?

Objective:Neuropsychiatric symptoms concerning mood are common in Alzheimer's disease (AD), but it is unclear if they are etiologically related to AD pathophysiology or due to factors considered to be non-pathogenic, such as small vessel cerebrovascular disease. New generation clinical trials for AD often enroll participants with evidence of AD pathophysiology, indexed by amyloid PET scanning, but who are cognitively asymptomatic. We used screening data from the Anti-Amyloid Treatment in Asymptomatic Alzheimer's (A4) study to examine the extent to which depressive symptoms are associated with amyloid pathophysiology and small vessel cerebrovascular disease, in the form of white matter hyperintensities (WMH).Participants and Methods:The A4 study randomizes cognitively healthy older adults with evidence of amyloid pathophysiology on PET scanning. We used screening data, which included amyloid status (positive, negative) by visual read, amyloid PET standard uptake value ratio (SUVR) in cortical regions, and MRI data acquired in a subset (n=1,197, mean age 71.6 +/- 4.8 years, 57% women) to quantitate total WMH volume. Depressive symptoms were evaluated with the 15-item Geriatric Depression Scale, which we used both as a continuous variable and to define 'depressed' and 'non-depressed' groups, based on a cut score of > 5. We examined whether 1) depressive symptoms and proportion of depressed individuals differed between amyloid positive and negative groups, 2) there is a relationship between amyloid SUVR and depressive symptoms that differs as a function of amyloid positivity status, and 3) there is a relationship between WMH volume and depressive symptoms that differs as a function of amyloid positivity status.Results:Although depressive symptom severity did not differ between groups (t=0.14, p=0.88), a greater proportion of individuals were classified as depressed in the amyloid negative group than the amyloid positive group (3.5% vs. 1.9%, X2=4.60, p=0.032). Increased amyloid SUVR was associated with increased GDS scores among amyloid positive individuals (r=0.117, p=0.002) but not among amyloid negative individuals (r=0.006, p=0.68, Positivity Status x SUVR interaction on GDS: ß=0.817, p=0.029). Increased WMH was associated with higher GDS scores (ß=0.105, p=0.017) but not differentially in amyloid positive and negative participants (Positivity Status x WMH interaction on GDS: ß=-0.010, p=0.243).Conclusions:These analyses have several implications. First, individuals who are screened to participate in a clinical trial but do not have evidence of amyloidosis may be misattributing concerns about underlying AD pathophysiology to depressive symptoms. Second, the severity of AD pathophysiology, indexed by amyloid PET SUVR, may drive a small increase in depressive symptomatology among individuals over visual diagnostic thresholds. Third, small vessel cerebrovascular changes are additionally associated with depressive symptoms but in a manner that is independent of AD pathophysiology. Overall, depressive symptoms and depression are likely multiply determined among prospective clinical trial participants for preclinical AD.

39 Relationships among Cardiovascular Risk Factors, White Matter Hyperintensities, and Depressive Symptoms in Black and White Older Adults

Objective:The vascular depression hypothesis posits that there is a relationship between vascular disease and geriatric depressive symptoms. Black Americans are at higher risk for cardiovascular disease (CVD) than their White counterparts. However, it is not fully understood whether risk for CVD or potentially related neurovascular changes have a differential relationship in Black and White Americans. We investigated differences in the relationships between white matter hyperintensities, risk for CVD, and depressive symptoms in Black and White older adults.Participants and Methods:Participants were derived from the National Alzheimer Coordinating Center database. Black (N = 120) and White (N = 120) participants were matched on age, sex, and education. White matter hyperintensity (WMH) and CVD burden data (sum of vascular conditions) on 320 individuals were analyzed (mean age = 75.9; 69.4% female). Age, sex, race, and education were included as covariates in separate regression models in which WMH and CVD burden predicted scores on the 15-item Geriatric Depression Scale (GDS-15). Follow-up stratified analyses were conducted to explore the relationship between WMH and CVD burden on GDS scores in the Black and White samples.Results:Lower WMH volume and higher CVD burden were associated with higher GDS scores in the total sample. Analyses stratified by race showed a positive effect of CVD burden on GDS scores only for the Black sample and a trend effect of WMH on GDS scores only for the White sample, with higher WMH volume associated with lower rather than higher GDS scores.Conclusions:These findings are consistent with previous research showing that WMH and CVD burden are related to depression in older adults. Contrary to expectation, WMH had a negative trend association with GDS scores in the White sample. Findings also suggest that different etiologies may play a role in the clinical presentation of depression in Black and White Americans. Additional research is needed to further explore the relationships among CVD, its neural correlates, and depressive symptoms in diverse samples.

Depressive symptoms and hippocampal volume in autosomal dominant Alzheimer's disease.

Depressive symptoms are among early behavioral changes in Alzheimer's disease (AD); however, the relationship between neurodegeneration and depressive symptoms remains inconclusive. To better understand this relationship in preclinical AD, we examined hippocampal volume and depressive symptoms in cognitively unimpaired carriers of the presenilin-1 (PSEN1) E280A mutation for autosomal dominant AD. A total of 27 PSEN1 mutation carriers and 26 non-carrier family members were included. Linear regression was used to test the relationship between hippocampal volume and 15-item Geriatric Depression Scale. Carriers and non-carriers did not differ in depressive symptoms or hippocampal volume. Within carriers, lower hippocampal volume was associated with greater depressive symptoms, which remained significant after adjusting for age and cognition. This relationship was not significant in non-carriers. Hippocampal neurodegeneration may underlie depressive symptoms in preclinical autosomal dominant AD. These findings provide support for the utility of targeting depressive symptoms in AD prevention. We compared unimpaired autosomal dominant Alzheimer's disease (AD) mutation carriers and non-carriers. Carriers and non-carriers did not differ in severity of depressive symptoms. In carriers, hippocampal volume was inversely associated with depressive symptoms. Depressive symptoms may be a useful target in AD prevention.

Associations of intrinsic capacity, fall risk and frailty in old inpatients.

This study explored the associations of intrinsic capacity (IC), fall risk, and frailty in geriatric inpatients. A total of 703 hospitalized patients aged 75 years or older were recruited for this retrospective observational study from Zhejiang Hospital using a comprehensive geriatric assessment. The IC composite score was constructed from the scores of the Chinese version of the Mini-Mental State Examination, Short Physical Performance Battery, Short Form Mini Nutritional Assessment, 15-item Geriatric Depression Scale, and self-reported hearing and vision impairment. Adverse outcomes were recorded as the fall risk and frailty using the Morse Fall Scale and the Clinical Frailty Scale. Spearman's correlation coefficient analyses and multivariate logistic regression models were used to explore the associations between IC, high fall risk, and frailty. Declined IC composite scores were associated with increased risks of falls [odds ratio (OR) = 0.64, 95% confidence interval (CI): 0.57-0.72] and frailty (OR = 0.45, 95%CI: 0.37-0.54) among older hospitalized patients after adjusting for the related potential confounders. In addition, decreased cognitive, vitality, locomotion, and psychological scores were associated with increased adverse health conditions, with ORs ranging from 0.26 to 0.70. Vision impairment was observed to increase the risk of frailty (OR = 0.42, 95%CI: 0.23-0.76) after adjusting for the related potential confounders. This study indicated that declined IC was associated with fall risk and frailty in older inpatients. Further prospective studies are needed to explore the longitudinal associations between baseline IC and subsequent risk of falls and frailty.

Cognitive frailty and its association with depression, anxiety and stress during the COVID-19 pandemic among older adults in the transforming cognitive frailty into later-life self-sufficiency (AGELESS) study.

Cognitive frailty describes the co-occurrence of cognitive impairment and physical frailty and is classified into reversible and irreversible phenotypes. Data on the impact of COVID-19 pandemic imposed lockdowns, locally known as the Movement Control Order (MCO), on the psychological status of cognitively frail older adults remain scarce. Therefore, this study aimed to determine the relationship between depression, anxiety, stress and cognitive frailty among older adults during the MCO. Participants aged above 60 years from three ageing cohorts in Malaysia were interviewed virtually. The Fatigue, Resistance, Ambulation, Illness and Loss of Weight scale, blind Montreal Cognitive Assessment, 15-item Geriatric Depression Scale, anxiety subscale of Depression, Anxiety and Stress Scale and four-item Perceived Stress Scale measured frailty, mild cognitive impairment (MCI), depression, anxiety and stress, respectively. Cognitive frailty data were available for 870 participants, age (mean ± SD) = 73.44 ± 6.32 years and 55.6% were women. Fifty-seven (6.6%) were robust, 24 (2.8%) had MCI, 451 (51.8%) were pre-frail, 164 (18.9%) were pre-frail+MCI, 119 (13.7%) were frail and 55 (6.3%) were frail+MCI. There were significant differences in depression and anxiety scores between the controlled MCO and recovery MCO. Using multinomial logistic regression, pre-frail (mean difference (95% confidence interval, CI) = 1.16 (0.932, 1.337), frail (1.49 (1.235, 1.803) and frail+MCI (1.49 (1.225, 1.822)) groups had significantly higher depression scores, frail (1.19 (1.030, 1.373)) and frail+MCI (1.24 (1.065, 1.439)) had significantly higher anxiety scores and pre-frail (1.50 (1.285, 1.761)), frail (1.74 (1.469, 2.062)) and frail+MCI (1.81 (1.508, 2.165)) had significantly higher stress scores upon adjustments for the potential confounders. The MCO was a potential confounder in the relationship between depression and prefrail+MCI (1.08 (0.898, 1.340)). Frail individuals with or without MCI had significantly higher depression, anxiety and stress than those who were robust. Increased depression and stress were also observed in the pre-frail group. Interventions to address psychological issues in older adults during the COVID-19 pandemic could target prefrail and frail individuals and need further evaluation.

Is overall and timing-specific physical activity associated with depression in older adults?

Regarding the circadian rhythm regulating an individual's response to external stimulation, it remains unclear whether older adults engaged in physical activity at different times of day may be differently related to depression symptoms. Thus, this study aimed to investigate the association between overall and timing-specific physical activity and depressive symptoms in older Taiwanese adults. This cross-sectional study was conducted at a medical center in Taipei City, Taiwan, between September 2020 and December 2021. The participants were community-dwelling older adults aged ≥65 who could walk independently and were not at high risk of cognitive dysfunction. Physical activity was measured using a triaxial accelerometer (GT3X+, ActiGraph) and categorized into timing-specific periods (morning: 06:01-12:00; afternoon: 12:01-18:00; evening: 18:01-24:00) as well as overall physical activity, which included both light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA). A 15-item Geriatric Depression Scale was utilized to assess and measure depressive symptoms. Multivariate linear regression models were estimated for data analysis. A total of 180 older adults (55.0% female; 80.5 ± 7.1 years old; 18.3% at risk of depression) were included. On average, the participants spent 237.3 (± 85.7) minutes in LPA per day and 12.8 (± 17.0) minutes in MVPA per day. The results showed that overall MVPA engagement was associated with lower depressive-symptom scores [B = -1.357, 95% CI (-2.561, -0.153)] in older adults. However, no significant associations were observed between overall LPA, timing-specific MVPA and LPA, and depression in older adults. To prevent depression in older adults, it is advisable to accumulate a higher amount of MVPA throughout the entire day rather than engage in LPA. Further studies employing a prospective design are necessary to validate and strengthen our findings.

Five-year changes of social activity and incident long-term care needs among depressed older adults: A 15-year follow up

ObjectivesTo examine the effects of changes in individual/multiple social activities between 65 and 70 years of age on incident long-term care (LTC) needs between 70 and 80 in older adults with depressive symptoms. MethodsParticipants were recruited from the New Integrated Suburban Seniority Investigation Project, an ongoing prospective cohort study. A total of 525 older adults with depressive symptoms were included. The validated 15-item Geriatric Depression Scale was used to assess depressive symptoms. A self-report questionnaire was used to measure social activities (social-related, learning, and personal). LTC needs was defined according to Japan's Long-term Care Insurance System. A competing risk model and a Laplace regression model were used to estimate the hazard ratios of LTC needs incidence and the 25th percentile difference in LTC-needs-free survival time and their 95% confidence intervals. ResultsOut of 4314 person-years of mild LTC needs, 108 individuals developed it. Participants who increased their frequency of learning activities have a lower risk of developing mild LTC needs. Increasing the frequency could also prolong LTC-needs-free survival time by approximately 2.61 years. Out of 4535 person-years for severe LTC needs, 54 individuals developed it. Participants with a continuous regular frequency of learning activities had a lower risk of developing severe LTC needs. However, the association between this frequency and LTC-needs-free survival time for severe LTC needs was insignificant in the multivariable models. ConclusionsIncreased frequency of learning activities reduced the risk of LTC needs among older adults with depressive symptoms and prolonged their LTC-needs-free survival time.

Factors associated with the core dimensions of spiritual health among older adults with chronic obstructive pulmonary disease: A cross-sectional study.

To investigate the level of spiritual health in older patients with chronic obstructive pulmonary disease (COPD) from the core dimensions and to explore its associated factors. A cross-sectional study. Participants were recruited from four hospitals between September 2020 and June 2021, using a convenience sampling. Older patients with COPD (n = 162) completed the demographic and disease-related information questionnaires, Function Assessment of Chronic Illness Therapy Spiritual Scale, 10-item Connor-Davidson Resilience Scale, General Self-efficacy Scale, Social Support Rating Scale, COPD Assessment Test, 15-item Geriatric Depression Scale and modified Medical Research Council Dyspnea Scale. Descriptive statistics, Pearson and Spearman correlation analyses, t-tests, one-way ANOVA and multiple linear regression models were used. Older patients with COPD have a moderate level of spiritual health. The multiple linear regression analysis showed that psychological resilience, general self-efficacy, social support, symptom burden and monthly income were associated with the core dimensions of spiritual health. Chinese older patients with COPD have a moderate level of spiritual health. Psychological resilience, general self-efficacy, social support, monthly income and symptom burden were associated with the core dimensions of spiritual health. This study is the first to investigate the level of spiritual health in older patients with COPD from the core dimensions and to explore its associated factors, providing a basis for developing spiritual intervention programs. Our findings can help us realize that intervention strategies of psychological resilience, general self-efficacy and social support can all be used to enhance spiritual health. Nurses should focus on the spiritual health of older COPD patients with high symptom burden and low monthly income. Although we did not directly involve patients and the public because of the COVID-19 pandemic, the results of the study will be disseminated to patients and the public through WeChat and seminars.

The trajectory of non-depressed suicidal ideation in community-dwelling older people in a rural area in Japan: a prospective longitudinal study with a 3-year follow-up.

Suicidal ideation is closely related to severe suicidal behaviour and is an important predictor of suicide attempt and completion, including in older people. Older people tend to have many opportunities to be conscious of death, and may have vague suicidal ideation because of various loss experiences, even if they are not depressed. We hypothesised that suicidal ideation among older people might be a risk factor for later transition to depression. The present study aimed to clarify risk factors that predict the incidence of depression in older people 3 years post-baseline in a rural area of Japan, and to examine the subsequent course of depression among non-depressed older people with suicidal ideation. In 2015 and 2018, survey questionnaires were mailed to residents aged 65 years and over living in a rural area in Japan. Participants were divided into a depression group and a non-depression group using 15-item Geriatric Depression Scale scores 3 years post-baseline. Logistic regression analysis was used to identify predictive factors of late-life depression 3 years post-baseline. We received 597 valid responses, with a 3-year follow-up rate of 78.8%. Regarding suicidal ideation, 6.7% of non-depressed older people exhibited suicidal ideation at baseline. Of these, 9.8% exhibited depression after 3 years post-baseline. Logistic regression analysis indicated that development of late-life depression is significantly associated with suicidal ideation, being female, and poor health-related quality of life (HRQOL). The results revealed that suicidal ideation, being female, and poor HRQOL were predictive factors of the development of late-life depression 3 years post-baseline in a rural area of Japan. These findings provide novel information regarding the transition to depression among community-dwelling older people who are not depressed but have suicidal ideation. Whereas suicidal ideation is considered to be a symptom of depression, the current results suggest that suicidal ideation may precede depression in some older people.

Exploring the occurrence and the risk factors of the desire for hastened death and depression in people with early-stage dementia in Greece.

To assess the factors associated with desire for hastened death and depression in early-stage dementia as well as the association between them. Also, to explore the mediator and moderator role of age in the relationship between depression and desire for hasten death. A prospective cross-sectional study including 100 patients diagnosed with early-stage dementia from a rehabilitation center between December 2018 and July 2019. Measurement tools used were the Mini-Mental State Examination, the Greek Montreal Cognitive Assessment, the Greek Schedule of Attitudes toward Hastened Death, and the Geriatric Depression Scale-15 item. Patients diagnosed with dementia as a result of Stroke history were excluded. Factors of multifactorial analysis significantly associated with desire for hastened death were as follows: age (p=0.009), marital status (p=0.001), and depression (p<0.001). The factor significantly associated with depression was age (p=0.001). Also, a mediation/moderation analysis has shown that depression and age are significant predictors of desire for hasten death. The desire for hastened death and depression in people diagnosed with early-stage dementia includes many components. Younger patients, men, higher educated patients, single, childless, and those with higher depression scores had higher desire for hastened death, while men and older patients had higher scores of desire for depression. Our study provides important information about the desire for hastened death and depression in early-stage dementia, their risk factors, and their association.

Effects of oral function and depressive tendencies on nutritional status in older adults requiring support or low-level care: An investigation using path analysis.

This study investigated the effects of differences in oral function and depressive tendencies on nutritional status in older adults requiring support or low-level care. In 106 older adult participants residing in nursing/care homes or participating in community-level preventive care activities, the Mini Nutritional Assessment-Short Form (MNA®-SF) for nutritional status and oral diadochokinesis (ODK), tongue pressure, and repetitive saliva swallowing test (RSST) for oral function, 15-item Geriatric Depression Scale (GDS), Diet-Related Quality of Life Scale-Short Form (DRQOL-SF), and Functional Independence Measure (FIM) were administered. Basic information, including cognitive function, was evaluated. Hierarchical MNA (dependent variable)-based multiple regression analysis was performed, followed by path analysis using factors with significant associations with MNA scores. RSST, ODK, tongue pressure, FIM, and DRQOL were positively correlated with MNA scores and GDS was negatively correlated. Hierarchical multiple regression demonstrated associations with tongue pressure, GDS, FIM, DRQOL scores, and gender. Path analysis confirmed significant paths from tongue pressure to MNA, tongue pressure to FIM, and FIM to MNA (P < .001). Significant paths were confirmed from GDS to MNA (P < .01), from DRQOL to MNA (P < .05), and from gender to MNA (P < .01). Tongue pressure, GDS, FIM, DRQOL scores, and gender were identified as factors that directly affect MNA. Tongue pressure showed the greatest effect and indirectly affected MNA via FIM. These findings emphasize the importance of early detection of low nutritional risk for preventing depression and oral function deterioration, and of evaluation of dietary satisfaction and improvement of quality of life in diets.

Association between Intrinsic Capacity and Sarcopenia in Hospitalized Older Patients.

This study aimed to clarify the association between intrinsic capacity (IC) and sarcopenia in hospitalized older patients. A cross-sectional study. Hospital-based. This study included 381 inpatients aged ≥ 60 years (225 men and 156 women). IC was evaluated in five domains defined by the World Health Organization: cognition (Mini-Mental State Examination), locomotion (Short Physical Performance Battery test), vitality (Short-Form Mini Nutritional Assessment), sensory (self-reported hearing and vision) and psychological (5-item Geriatric Depression Scale) capacities. IC composite score (0-5) was calculated based on five domains, with lower scores representing greater IC. Sarcopenia was defined in accordance with the criteria recommended by the Asian Working Group for Sarcopenia (AWGS) 2019. Multiple linear and logistic regressions were performed to explore the associations between IC composite score and IC domains with sarcopenia and its defining components. The mean age of 381 patients included was 81.95±8.42 years. Of them, 128 (33.6%) patients had sarcopenia. The median IC composite score was 1 (1, 2). Cognition, locomotion, vitality, sensory and psychological capacities were impaired in 22.6%, 63.5%, 18.9%, 27.3% and 11.3% of patients. Multiple linear regression analyses showed that favorable IC domain scores in cognition, locomotion and vitality were associated with a stronger handgrip strength. A higher vitality score was associated with a greater appendicular skeletal muscle mass index (ASMI), and a higher locomotion score was associated with a greater gait speed. The multiple logistic regression analysis showed that only vitality impairment was associated with sarcopenia. A higher IC composite score was associated with higher risks of sarcopenia, as well as low ASMI, handgrip strength and gait speed. This study indicated that a more serious impairment of IC was associated with a greater risk of sarcopenia. Vitality was the domain most strongly associated with sarcopenia. IC may be employed to detect and manage sarcopenia.

UQE-3D: a usability evaluation method of 3D user interfaces for the elderly

Health professionals could use 3D user interfaces to support elderly rehabilitation, offering fun and engagement during physical and cognitive activities. The evaluation of these immersive applications needs instruments designed for the specific context. This study presents and validates a new usability evaluation method for 3D user interfaces for the elderly. We developed the UQE-3D questionnaire from previous studies keeping in mind the 3D aspects and technological language suitable for the target public. To apply it, we used a protocol considering a demographic questionnaire, the Mini-Mental State Exam, the 15-item Geriatric Depression Scale, the SUS Scale, the UQE-3D, and a structured interview. We also executed an experiment considering a heterogeneous group with 30 subjects (60+ years), where seven participants were institutionalized elderly. UQE-3D presented good results showing a mean score of 82.60 (range 1-100). UQE-3D and SUS scores did not show a statistically significant difference, highlighting the UQE-3D to be sufficient and effective in identifying the usability issues seen in the assessment of 3D user interfaces for the elderly. The method has the potential to evaluate and ensure the quality of 3D context-specific applications, considering appropriate terminology and contributing to the development of technologies fitting for the elderly.

Better Handgrip Strength Is Related to the Lower Prevalence of Pain and Anxiety in Community-Dwelling Older Adults.

Although handgrip strength (HGS) may be treated as a biomarker of many health problems, there is little evidence on the potential role of HGS in the prevention of pain or anxiety in older adults. We investigated the relationship of HGS to the presence of pain and anxiety among community-dwelling older adults. The study was performed in 2038 outpatients, aged 60 to 106 years. The Jamar hand-held hydraulic dynamometer was used to measure HGS. The prevalence of pain and anxiety was assessed with the Euroqol 5D questionnaire. Symptoms of depression were recorded with 15-item Geriatric Depression Scale (GDS). In the multivariate logistic regression model taking into account age, sex, BMI and concomitant diseases, the significant influence of HGS on the presence of pain (odds ratio [OR] = 0.988) in the entire study population and among men (OR = 0.983) was found. HGS was a significant independent predictor for the presence of anxiety in the entire study population (OR = 0.987), in women (OR = 0.985) and in men (OR = 0.988). In the fully adjusted model with included GDS, 1 kg higher HGS was still associated with 1.2% and 1.3% lower probability of the presence of pain and anxiety, respectively. We conclude that low HGS is associated with the presence of pain and anxiety among older adults, independent of age, sex, depression symptoms and concomitant chronic diseases. Future research should assess whether improvement of HGS would alleviate psychological dysfunction in older adults.

The combination of olfactory dysfunction and depression increases the risk of incident dementia in older adults.

Olfactory dysfunction and depression are common in later life, and both have been presented as risk factors for dementia. Our purpose was to investigate the associations between these two risk factors and determine if they had an additive effect on dementia risk. Olfactory function was assessed using the Brief Smell Identification Test (BSIT), and depression was classified using a combination of the 15-item Geriatric Depression Scale (GDS) score and current antidepressant use. Cross-sectional associations between depression and olfactory function were examined using correlations. Cox regression analyses were conducted to examine the longitudinal relationship between olfaction and depression and incident dementia across 12-years of follow-up. Participants were 780 older adults (aged 70-90 years; 56.5% female) from the Sydney Memory and Ageing Study (MAS) without a diagnosis of dementia at baseline. Partial correlation revealed a nonsignificant association between baseline depression and olfactory function after accounting for covariates (r = -.051, p = .173). Cox regression showed that depression at baseline (hazard ratio = 1.706, 95% CI 1.185-2.456, p = .004) and lower BSIT scores (HR = .845, 95%CI .789-.905, p < .001) were independently associated with a higher risk of incident dementia across 12 years. Entering both predictors together improved the overall predictive power of the model. Lower olfactory identification scores and depressive symptoms predict incident dementia over 12 years. The use of BSIT scores and depression in conjunction provides a greater ability to predict dementia than either used alone. Assessment of olfactory function and depression screening may provide clinical utility in the early detection of dementia.

The effects of a magic-based intervention on self-esteem, depressive symptoms, and quality of life among community-dwelling older adults: a randomised controlled trial.

Magic-based programs have been utilised to enhance well-being across various health aspects. However, there is a lack of studies on whether performing magic tricks can provide mental health benefits for older adults living in the community. Therefore, this study aims to investigate the effects of a magic-based intervention program on self-esteem, depressive symptoms, and quality of life (QOL), and to examine the relationship between these factors in older adults. Thirty-eight participants, aged 60-90 years, were randomly assigned to either a magic intervention group or a control group. The magic intervention program, tailored for older adults, was conducted for 90 min, twice weekly, over 6 weeks. The Rosenberg Self-Esteem Scale (RSE), the 15-item Geriatric Depression Scale (GDS-15), and the World Health Organization Quality of Life-BREF scores were measured and analyzed in both groups before and after the intervention. The magic-based intervention significantly increased self-esteem and reduced depressive symptoms in older adults, with large effect sizes. However, no significant impact on QOL was observed. Additionally, no significant correlation was found between the improvement in self-esteem and the reduction in depressive levels. Despite this, a moderate but significant negative correlation was detected between the post-intervention scores of RSE and GDS-15 in the magic intervention group. The study demonstrated that the magic intervention program was beneficial in promoting mental health in community-dwelling older adults. Implementing magic programs in communities appears to be an effective approach to enhance self-esteem and alleviate depressive symptoms in the older population.

Association between serum oxytocin levels and depressive state in community-dwelling older adults: A cross-sectional study.

Identifying peripheral biomarkers related to the prevention or modification of unhealthy mental conditions in older adults would be extremely beneficial. This study aimed to evaluate serum oxytocin levels in older adults living in a rural community and their association with cognitive function, anxiety, depressive state, and well-being. This survey was conducted between November 2016 and September 2017 in Kurokawa-cho, Imari, Saga Prefecture, Japan, among people aged ≥65 years. Blood samples were collected from the participants for serum oxytocin level analysis, which was performed using peptide enzyme immunoassay. Participants underwent neuropsychological assessments, including the Mini-Mental State Examination, Clinical Dementia Rating, Frontal Assessment Battery, State-Trait Anxiety Inventory, 15-item Geriatric Depression Scale, and 17-item Philadelphia Geriatric Center Morale Scale. We examined the association between serum oxytocin levels and neuropsychological assessment results. Out of 94 participants, 25 were men and 69 were women, with mean ages of 78.24 ± 3.85 years and 78.10 ± 5.43 years, respectively. Serum oxytocin levels were negatively associated with 15-item Geriatric Depression Scale scores. Additionally, nondepressive state/depressive state was classified by the 15-item Geriatric Depression Scale (cut-off 5/6). Logistic regression analysis showed that higher serum oxytocin levels tended to be associated with a less depressive state at that time. Serum oxytocin levels may be associated with depressive state in adults aged ≥65 years.

Longitudinal decline in striatal dopamine transporter binding in Parkinson’s disease: associations with apathy and anhedonia

BackgroundMotivational symptoms such as apathy and anhedonia are common in Parkinson’s disease (PD), respond poorly to treatment, and are hypothesised to share underlying neural mechanisms. Striatal dopaminergic dysfunction is considered...
