MALE BREAST CANCER IN OLDER ADULTS BELONGING TO THE LOWER-INCOME GROUP

Abstract Male breast cancer is a rare type of cancer constituting around 1% of male malignancies. Cases of 21 elderly (aged>60) patients diagnosed with breast cancer were studied with respect to age of onset, treatment choices, access to care, ability to perform activities of daily living (ADL) from CMIG, resource centre on ageing in east India. All 21 patients belonged to lower income group in society and the study was conducted over a 5 year period of 2018-2022. Primary symptom leading to diagnosis was self-detection of lump and the median time of diagnosis from onset of symptoms was 6 months. Twenty of the 21 patients were diagnosed with Stage III or Stage IV breast cancer and 1 patient was diagnosed with Stage I cancer. The average age of diagnosis of the patients was found to be 69 years. The main method of treatment was surgery for patient diagnosed in Stage I and surgery followed by chemotherapy and radiation therapy for the rest. None of the patients underwent hormone therapy and information regarding presence of hormone receptors was not available in all cases. Five of the 21 cases reported metastasis- 4 in bone and 1 in lung. Spouse or adult children were found to be caregivers with no access to trained caregivers or counsellors. All patients showed moderate decline in motor function and ADL after surgery alongwith susceptibility to fall or injury. Free hand exercises showed slight improvement. Further studies can attract state funding and influence heath policies for lower income groups.

Perioperative treatments for and postoperative activity of daily living of patients with early-stage breast cancer according to age group: A retrospective observational study

IntroductionThe number of older patients with breast cancer is increasing worldwide. However, no studies have clarified to what extent activities of daily living (ADL) decline in older patients after surgery. This study aimed to identify perioperative treatments and the proportion of patients with a postoperative decline in ADL among those with early-stage breast cancer, according to age groups (<65, 65–74, ≥75 years). Materials and methodsThis retrospective study used healthcare utilization data of women aged ≥40 years who were diagnosed with breast cancer in 431 Japanese hospitals. Patients who underwent breast conserving surgery and mastectomy at clinical stages 0–III were included. ADL were assessed using the Barthel index (100 points indicated independent ADL). ResultsOverall, 37,161 patients were analyzed, including 17,313 undergoing a breast conserving surgery and 19,848 undergoing a mastectomy. The difference in the proportion of patients with a postoperative decline in ADL between those in the <65-year and ≥75-year group who underwent mastectomy was approximately 1%. In each age group, a higher proportion of patients received adjuvant chemotherapy (9.4–27.5% for breast conserving surgery; 15.6–40.3% for mastectomy) than neoadjuvant chemotherapy (breast conserving surgery, 2.1–12.0%; mastectomy, 3.0–18.1%). A lower proportion of patients in the ≥75-year group underwent radiotherapy than that in the <65-year group. ConclusionPhysical burden of surgery was low in both younger and older patients. Low proportions of patients in the ≥75-year group who underwent surgery received neoadjuvant and adjuvant chemotherapy and adjuvant radiotherapy. Healthcare providers should inform this to patients.

Neurofunctional Correlates of Activities of Daily Living in Patients with Posterior Cortical Atrophy

AbstractBackgroundResearch on posterior cortical atrophy (PCA) has concentrated on cognitive decline, especially visual processing deficits. However, few studies have focused on the activities of daily living (ADL), and no study has investigated the neurometabolic basis of ADL impairments. We aimed to identify regions of hypometabolism associated with ADL in PCA patients.MethodTwenty‐nine PCA patients, 35 typical Alzheimer’s disease (tAD) patients, and 26 healthy volunteers were recruited. Each subject completed a scale for total ADL [TADL, including basic ADL (BADL) and instrumental ADL (IADL) subscales] and 18F fluorodeoxyglucose positron emission tomography. Voxel‐wise multivariable regression analysis was conducted at the level of the whole‐brain, PCA‐related hypometabolism patterns, and PCA‐specific hypometabolism patterns.ResultThe general cognitive status of PCA patients was similar to tAD patients; however, they performed worse in TADL, BADL, and IADL. In all analysis levels, TADL was associated with the bilateral parietal lobe, including the right superior parietal lobe, right inferior parietal cortex, right angular gyrus, and left superior parietal lobe. BADL was associated with the bilateral parietal lobe located in the right superior parietal lobe, right inferior parietal cortex, and left superior parietal lobe. IADL was associated with the bilateral superior parietal lobe. Bilateral superior parietal lobe hypometabolism was associated with TADL, BADL, and IADL.ConclusionHypo‐metabolism in the bilateral superior parietal lobes contributes to the decline of ADL in PCA, which is a promising target for future non‐invasive neuromodulation interventions.

Is Carer Management Style Associated with Longitudinal Functional Decline in Dementia?

Various intrinsic (related to dementia) and extrinsic (not related to dementia) factors have been suggested to contribute separately to disability in people living with dementia (PLwD). To investigate if the combination of specific intrinsic and extrinsic factors at baseline is associated with longitudinal declines in activities of daily living (ADL) performance of PLwD at 12-month follow-up. 141 community-dwelling PLwD-carer dyads were assessed on their global cognition (ACE-III), apathy (CBI-R), carer management styles (DMSS), medical comorbidities (CCI), and ADL performance (DAD) at baseline, and for a subset of participants (n = 53), at 12-month follow-up. Multiple linear regression models were run to assess: 1) the relationships between PLwD's DAD scores and the remaining variables at baseline and 2) whether these variables' scores at baseline were associated with longitudinal change in the PLwD's DAD scores. At baseline, having lower ACE-III (β= 0.354, p < 0.001), higher CBI-R (β= -0.284, p < 0.001), higher DMSS criticism (β= -0.367, p = 0.013), lower DMSS encouragement (β= 0.370, p = 0.014), and higher CCI scores (β= -2.475, p = 0.023) were significantly associated with having lower DAD scores. The PLwD's DAD scores significantly declined from baseline to follow-up (p < 0.001, d = 1.15), however this decline was not associated with the baseline scores of any of the independent variables. Instead, it was associated with declines in the PLwD's ACE-III scores from baseline to follow-up (β= 1.021, p = 0.001). In our limited sample, cognitive changes seem to be the main factor underlying longitudinal decline in ADL performance for PLwD. Carer management styles appear associated with current ADL performance but not with longitudinal ADL decline.

Association between decreased neck circumference and impaired activities of daily living among older adults in long-term care.

Assessment interventions for the decline of activities of daily living (ADLs) in older adults are crucial, as ADL decline increases hospitalization duration and mortality risk. Decreased neck circumference may result in various physical dysfunctions, including malnutrition. However, the association between neck circumference and ADLs has not been fully clarified. This study aimed to determine the association between decreased neck circumference and ADLs in older adults requiring long-term care. The study included 152 older adults deemed to require support or care under Japan's long-term care insurance system. Neck circumference was measured just below the thyroid cartilage with a measuring tape. The Barthel index was used to evaluate ADLs, and skeletal muscle mass and nutritional status were assessed by bioelectrical impedance analysis instruments. A multivariate analysis was conducted to investigate the association between neck circumference and ADLs. Neck circumference demonstrated a significant inverse correlation with age and a significant positive correlation with body mass index, skeletal muscle mass index, phase angle, and Barthel index. In the multivariate analysis, ADLs was significantly associated with neck circumference (odds ratio [OR] = 0.51, P = 0.002) and phase angle (OR = 0.04, P < 0.001). Neck circumference is associated with age, skeletal muscle mass, and nutritional status. Furthermore, a decrease in neck circumferenceis suggested as an independent risk factor for ADL decline in older adults requiring long-term care. Geriatr Gerontol Int 2023; 23: 906-911.

Factors associated with changes in activities of daily living from admission to discharge among older patients with pneumonia

IntroductionIt has not been fully elucidated that nutritional parameters affect the change of activities of daily living (ADL) during pneumonia treatment. This study assessed the impact of nutritional status, including erector spinae muscle (ESM) size on ADL changes from admission to discharge among older patients with community-acquired pneumonia (CAP). MethodsWe retrospectively included patients (age: ≥65 years) who were admitted to the hospital for CAP and underwent chest computed tomography (CT) on admission. ADL was evaluated using the Barthel index, and patients were divided into the maintained or improved ADL group and the declined ADL group from admission through discharge. The ESM cross-sectional area was measured on a single-slice CT image. Logistic regression models were applied for assessing factors associated with changes in ADL. ResultsA total of 523 patients hospitalized for CAP (median age 86 years) were evaluated. The declined group had significantly higher ADL levels on admission, a greater frequency of smoking history and malignancy, and a lower frequency of cerebrovascular disease and dementia. No significant difference in ESM size was observed between the groups. Multivariate analysis revealed that higher ADL levels on admission (odds ratio 1.034, interquartile range 1.026–1.043) and malignancy (3.002, 1.150–7.836) were associated with a decline in ADL, whereas cerebrovascular disease (0.579, 0.373–0.900) was related to improvement or maintenance of ADL. ConclusionsAlthough nutritional status might not affect the change of ADL among older patients hospitalized with pneumonia, a cerebrovascular disease history may be a good predictor for ADL improvement.

Pre-stroke activities of daily living do not predict functional decline after stroke in a cohort of community dwelling older subjects at risk for vascular disease

Background & purposePre-stroke impairment of activities of daily living (ADL) is considered a major determinant for functional outcome after stroke. However, findings are based on studies in stroke patients in which pre-stroke information is gathered retrospectively, with inherent risks of selection and recall bias. The objective of this study was to verify the predictive value of pre-stroke ADL with respect to ADL decline in a large prospective cohort of community dwelling older subjects with known vascular risk factors or vascular disease, thereby minimizing selection and recall bias. MethodsWithin the four-year study follow-up of a cohort including 5,804 community dwelling older subjects from three countries at risk for vascular disease, incident stroke survivors were identified. Incident myocardial infarction (MI) survivors and the remaining study survivors without incident vascular events served as comparison groups. Multivariate logistic regression analyses for each of the aforementioned groups were performed to assess associations between pre-stroke ADL by the Barthel Index (BI) and Instrumental Activities of Daily Living (IADL) scale and risk for ADL decline. ResultsIn stroke survivors, neither pre-event BI (n = 230, OR 1.00 (95% CI 0.83–1.23)) nor IADL (OR 1.07 (95% CI 0.94 – 1.20)) predicted risk of post-stroke ADL decline in contrast to ADL decline after MI (n = 443, OR 0.83 (95% CI 0.70–0.98) and 0.87 (95% CI 0.78–0.97) respectively) and the group without vascular events (n = 4336, OR 0.85 (95% CI 0.78–0.92) and 0.87 (95% CI 0.83–0.92) respectively). ConclusionsIn the present prospective cohort of community dwelling older subjects with known vascular risk factors, pre-stroke ADL measured by BI and IADL scale did not predict post-stroke ADL decline.

Associations of postoperative delirium with activities of daily living in older people after major surgery: A prospective cohort study.

To assess the association of postoperative delirium developed in the post-anaesthetic care unit (PACU) with older patients' ability to perform activities of daily living (ADL) during the first five postoperative days. Previous studies have focused on the association between postoperative delirium and long-term function decline, however the association between postoperative delirium and the ability to perform ADL, particularly in the immediate postoperative period, needs further investigation. A prospective cohort study. A total of 271 older patients who underwent elective or emergency surgery at a tertiary care hospital in Victoria, Australia, participated in the study. Data were collected between July 2021 and December 2021. Delirium was assessed using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). The Katz Index of Independence in Activities of Daily Living (KATZ ADL) scale was used to measure ADL. ADL was assessed preoperatively and daily during the first five postoperative days. The STROBE checklist was used to report this study. Results showed that 44 (16.2%) patients developed new episode of delirium. Postoperative delirium was independently associated with decline in ADL (RR = 2.83, 95% CI = 2.71-2.97; p < 0.001). Postoperative delirium was associated with a decline in ADL among older people during the first five postoperative days. Screening for delirium in the PACU is essential to identify delirium during the early stages of postoperative period and implement a timely comprehensive plan. Delirium assessment of older patients in the PACU, and for at least the first five postoperative days, is strongly recommended. We also recommend engagement of patients in a focused physical and cognitive daily activity plan, particularly for older patients undergoing major surgery. Patients and nurses helped in data collection at a tertiary care hospital.

Heart failure with comorbid dementia: Association with clinical characteristics and outcomes.

Heart failure (HF) and dementia both have profound effects on function and mortality in older persons. However, we have limited knowledge about the impact of co-occurring HF and dementia. Our goal was to understand how often persons with HF have dementia and the impact of their co-occurrence. Retrospective analysis of participants (age > 65) in the 2015 wave of the nationally representative Health and Aging Trends Study (NHATS) with linkage to Medicare claims. 912 participants with HF (45% older than 80, 51% women) using Medicare claims. We used the validated NHATS dementia algorithm to identify those with probable dementia. Outcomes of interest included the need for help with activities of daily living (ADLs) and instrumental activities of daily living (IADLs) at baseline, functional decline, hospitalization over 1 year, and mortality over 2-years. Baseline functional status, functional decline, and hospitalization were compared using adjusted logistic regression, mortality was analyzed using adjusted Cox regression models adjusted for demographics, socio-economic status, baseline health, and baseline functional status. 200 (21%) of the participants with HF also had dementia. For each I/ADL, patients with both HF and dementia were more likely to need help than those with HF without dementia. 71.8% of participants with HF and dementia needed help with medications versus 16.6% with HF without dementia (p < 0.001). Having HF and dementia was associated with an increased risk of requiring help with additional ADLs after one year (aOR = 2.69, 95% CI 1.53, 4.73). Participants with HF and dementia had an increased risk of being hospitalized within one year (aOR = 2.02 95% CI 1.16, 3.54), or dying within two years (aHR = 1.52 95% CI 1.03, 2.26). One-fifth of persons over age 65 with HF also have comorbid dementia. Co-occurring HF and dementia markedly increase functional impairment and subsequent ADL decline, hospitalization, and death. These results highlight the need for physician awareness for signs of dementia, and appropriate adjustments in the management of HF.

Factors affecting activities of daily living among patients with Wilson disease.

Wilson disease (WD) is a congenital copper metabolism disorder with various manifestations and can be treated with oral medication. This study examined the factors related to decline in activities of daily living (ADL) in patients with WD as research in this area remains limited. We enrolled 308 patients with WD, including patients who participated in a national survey and those who sought cares at the Department of Pediatrics, Toho University Ohashi Medical Center, from 2016 to 2017. We analyzed the association between ADL decline and factors including age at diagnosis, period from diagnosis to survey, hepatic symptoms, neurological signs, and psychiatric presentation at diagnosis. The relative risks (RRs) for ADL decline were estimated for each factor using multivariate modified Poisson regression analysis. Overall, 97 out of 308 (31.5%) patients experienced ADL decline. After adjusting for explanatory variables, regression analysis revealed that factors significantly associated with ADL decline were a period of ≥20 years from diagnosis to survey (adjusted RR = 2.34, 95% confidence interval [CI]: 1.47-3.74), hepatic symptoms with splenomegaly (adjusted RR = 2.57, 95% CI: 1.26-5.24), mild neurological signs (adjusted RR = 3.20, 95% CI: 1.96-5.23), and severe neurological signs (adjusted RR = 3.63, 95% CI: 2.28-5.77). Neurological signs, hepatic symptoms with splenomegaly, and a period of 20 years from diagnosis to survey are associated with ADL decline. Thus, careful assessment of patients for these factors is necessary, and these findings may guide future efforts to improve patient prognosis.

Neurofunctional Correlates of Activities of Daily Living in Patients with Posterior Cortical Atrophy.

Research on posterior cortical atrophy (PCA) has focused on cognitive decline, especially visual processing deficits. However, few studies have examined the impact of PCA on activities of daily living (ADL) and the neurofunctional and neuroanatomic bases of ADL. To identify brain regions associated with ADL in PCA patients. A total of 29 PCA patients, 35 typical Alzheimer's disease (tAD) patients, and 26 healthy volunteers were recruited. Each subject completed an ADL questionnaire that included basic and instrumental subscales (BADL and IADL, respectively), and underwent hybrid magnetic resonance imaging and 18F fluorodeoxyglucose positron emission tomography. Voxel-wise regression multivariable analysis was conducted to identify specific brain regions associated with ADL. General cognitive status was similar between PCA and tAD patients; however, the former had lower total ADL scores and BADL and IADL scores. All three scores were associated with hypometabolism in bilateral parietal lobes (especially bilateral superior parietal gyri) at the whole-brain level, PCA-related hypometabolism level, and PCA-specific hypometabolism level. A cluster that included the right superior parietal gyrus showed an ADL×group interaction effect that was correlated with the total ADL score in the PCA group (r = -0.6908, p = 9.3599e-5) but not in the tAD group (r = 0.1006, p = 0.5904). There was no significant association between gray matter density and ADL scores. Hypometabolism in bilateral superior parietal lobes contributes to a decline in ADL in patients with PCA and can potentially be targeted by noninvasive neuromodulatory interventions.

Effects of Daily Consumption of Soy Products on Basic/Instrumental Activities of Daily Living in Community-Dwelling Japanese Women Aged 75 Years and Older: A 4-Year Cohort Study.

Since soy isoflavones compensate for age-related estrogen reduction, adequate intake of soy products may prevent the decline in activities of daily living (ADL) due to estrogen reduction in women. However, it is unclear whether regular soy product intake prevents ADL decline. This study examined the effects of soy product consumption on basic/instrumental ADL (BADL/IADL) in Japanese women 75 years or older for 4 years. The subject population consisted of 1289 women aged 75 years or older living in Tokyo who underwent private health examinations in 2008. For 1114 (or 1042) participants without baseline BADL (or IADL) disability, we examined the association between baseline soy product consumption frequency and the BADL (or IADL) disabilities 4 years later using logistic regression analyses. The models were adjusted for baseline age, or further for dietary variety for food groups other than soy products, exercise and sport participation, smoking, pre-existing disease number, and body mass index. Regardless of adjustment for potential confounding factors, less frequent soy product consumption was associated with higher BADL or IADL disability incidence. In the fully adjusted models, the trend toward a higher incidence of disabilities with less frequent soy product consumption was statistically significant for both BADL (p = 0.001) and IADL (p = 0.007). Those who consumed soy products more frequently at baseline were less likely to develop BADL and IADL disabilities after 4 years than those who did not. The results show that daily soy product consumption may prevent functional ADL decline in older Japanese women.

PS-P11-2: THE PATTERN OF PHYSICAL DISABILITY AND DETERMINANTS OF ACTIVITIES OF DAILY LIVING AMONG DIABETIC PATIENTS IN BANGLADESH: A CROSS-SECTIONAL ANALYSIS.

Objective: Diabetes mellitus is a known predictor of physical disability and decline in activities of daily living (ADL); however, there are existing controversies about the factors explaining the association between diabetes and disability. Therefore, we assessed the proportion of physical disabilities and possible factors associated with ADL decline among diabetic patients in Bangladesh. Design and Methods: We conducted a cross-sectional study among 480 diabetic individuals from a tertiary level hospital in Dhaka, Bangladesh, aged between 40 and 85 years. For determining the ADL decline, we used the Katz Index Scoring, the highest score of 6 indicates no ADL decline. We divided patients into two groups depending on ADL impairment to compare the population characteristics using the unpaired Students t-test or Wilcoxon rank-sum test for continuous variables and the chi-squared test for categorical variables. Age, sex, educational attainment, household expenditure, BMI, HbA1c, hypertension, and medication adherence to anti-diabetic drugs were included in the statistical models. We defined any ADL decline as an event, and multivariable logistic regression was performed to assess the factors associated with ADL decline. Results: The mean age of the participants was 59.0 (standard deviation [SD], 7.0) years. The majority of the participants (76.3%) had at least some sort of physical disability. Age, educational attainment, household expenditure, systolic blood pressure, waist circumference, quality of life, and comorbidities were different among the groups stratified by ADL impairment status. In multivariable logistic regression analysis after adjusting for all covariates simultaneously, age (OR, 95% CI: 1.35, 1.20–1.75), lower educational attainment (0.97, 0.94–0.99), BMI (1.40, 1.12–1.75), existing comorbidities (2.79, 1.48–5.25) and uncontrolled diabetes (1.35,1.10–1.45) were independently associated with ADL decline among diabetic population. Conclusions: Physical disability was common, and ADL decline was associated with age, educational attainment, BMI, comorbidities, and uncontrolled diabetes among diabetic patients in Bangladesh.

Decreased Physical and Daily Living Activities in Patients with Peripheral Arterial Disease on Hemodialysis.

Decreased physical activity and activities of daily living (ADL) in patients on hemodialysis (HD) are associated with a poor prognosis. Additionally, comorbid peripheral arterial disease is associated with further deterioration. We conducted a cross-sectional study of ADL difficulty and life-space assessment (LSA) in three groups of patients on hemodialysis according to their ankle-brachial index (ABI) values. The 164 patients were divided into ABI Low (ABI < 0.9), Normal (0.9 ≤ ABI < 1.3), and High (1.3 ≤ ABI) groups, and compared using analysis of covariance with LSA and ADL difficulty adjusted for age. The Kihon checklist (KCL) was used to assess the presence of frailty. The LSA was lower in the Low group than in the High group (F = 3.192, p = 0.044). Similarly, the ADL difficulty was significantly lower in the Low group than in the Normal group (F = 3.659, p = 0.028). In the Low group, the proportion of patients with frailty was 47.1% and KCL physical was significantly lower, indicating that patients on HD with a lower ABI had a higher prevalence of frailty and lower LSA and ADL difficulty. In conclusion, patients on HD with decreased ABI values most likely exhibit decline in physical activity and ADL due to frailty and claudication.

A longitudinal study of disability in activities of daily living andactivity restriction-induced fear of falling among Korean older people.

This study examined the effects of the fear of falling (FOF) alone and fear-associated activity restriction (FAR) on future activities of daily living (ADL) disability and analysed predictors of ADL disability among community-dwelling older people with and without FAR. This prospective study involved secondary data analysis of the Korean Longitudinal Study of Aging. We obtained data from 5074 community-dwelling older adults. Generalized estimating equations were used to identify the predictors of changes in ADL disability between 2008 and 2018. Compared with FOF alone, FAR was significantly related to changes in ADL disability. Being older, living with others and having poor self-rated health status were associated with future ADL disability in participants without FAR. Weakened grip strength and social engagement were associated with future ADL disability in those with FAR. Nurses must consider the impact of FAR on future ADL decline and implement tailored interventions. No Patient or Public Contribution.

Nutritional Management in Elderly CKD Patients in Japan.

The munber of chronic kidney disease (CKD) patients is increasing globally because kidney function is affected by aging and lifestyle habits. Malnutrition, muscle weakness, and a decline in activities of daily living (ADL) are often observed in elderly CKD patients and dialysis patients, and are related to their CKD prognosis and life prognoses. Chronic inflammation and atherosclerotic disease are associated with malnutrition. Because malnutrition and its related factors affect patients' prognoses, it is necessary to identify and treat patients with malnutrition at an early stage. The state in which the stored protein and energy sources are reduced in CKD is called protein energy wasting (PEW). PEW is diagnosed on the basis of biochemical test findings such as hypoalbuminemia, unhealthy physique, and decreased muscle mass and dietary intake. For evaluating PEW, a complex nutritional index taking into account the pathophysiology specific to CKD patients is useful. Not only nutritional therapy but also exercise therapy is necessary to stop the vicious cycle associated with PEW and the decline in ADL.

Effect of a multimodal non-pharmacological intervention on older people with dementia: a single-case experimental design study

BackgroundOlder people with dementia (PWD) in nursing homes (NHs) tend to have decreased cognitive function, which may cause behavioral and psychological symptoms of dementia (BPSDs) and hinder activities of daily living (ADLs). Therefore, taking measures against the cognitive decline of PWD in NH and, in turn, the decline of BPSDs and ADLs is crucial. The purpose of this study was to test whether a multimodal non-pharmacological intervention (MNPI) is effective in maintaining and improving global cognitive function, BPSDs, and ADLs in PWD in NHs.MethodsAn intervention study using a single-case AB design was conducted in three subjects in NHs. During the non-intervention phase, participants underwent follow-up assessments, and during the intervention phase, they participated in an MNPI. The ABC Dementia Scale (which concurrently assesses ADLs [“A”], BPSDs [“B”], and cognitive function [“C”]) was used for the assessment.ResultsOne of the three patients showed improvement in dementia severity, global cognitive function, ADLs, and BPSDs. However, the other two participants showed no improvement following the MNPI, although the possibility of a maintenance effect remained.ConclusionAlthough there is room for improvement of the MNPI, it may be effective in maintaining and improving cognitive function, ADLs, and BPSD, in PWD in NHs.Trial registrationThe University Hospital Medical Information Network Clinical Trials Registry (http://www.umin.ac.jp/, No. UMIN000045858, registration date: November 1, 2021).

Muscle Endurance and Self-Perceived Fatigue Predict Decline in Gait Speed and Activities of Daily Living After 1-Year Follow-Up: Results From the BUTTERFLY Study.

Fatigue might influence the losses in activities of daily living (ADL). When fatigue parameters are present before the experience of losses in ADL and gait speed, they can be used as early warning signals. This study aimed to explore the predictive value of muscle endurance and fatigue on changes in ADL and gait speed in community-dwelling older adults aged 80 and older. Three hundred twenty four community-dwelling older adults aged 80 and older of the BUTTERFLY study were assessed after 1 year for muscle endurance, self-perceived fatigue, ADL, and gait speed. Exploratory factor analysis (EFA) was performed to explore, whether there is an underlying arrangement of the fatigue parameters. Mediating logistic regression analyses were used to investigate whether muscle endurance mediated by self-perceived fatigue predicts the decline in gait speed and ADL after 1-year follow-up. EFA indicated a 2-factor model (muscle endurance factor and self-perceived fatigue factor) and had a moderate fit (X2: 374.81, df: 2, comparative fit index; 0.710, Tucker-Lewis index (TLI): 0.961, root mean square error of approximation [90%]: 0.048 [0.00-0.90]). Muscle endurance mediated by self-perceived fatigue had an indirect effect on the prediction of decline in Basal-ADL (-0.27), Instrumental-ADL (-0.25), and gait speed (-0.28) after 1-year follow-up. This study showed that low muscle endurance combined with high self-perceived fatigue can predict changes in ADL after 1-year follow-up. These parameters might be very suitable for use in evaluating intrinsic capacity and can help to reduce the limitations in clinical usage of the vitality domain in the framework of intrinsic capacity.

A Lower CD4+/CD8+ Ratio Predicts Activities of Daily Living Decline Among Older Adults with HIV.

Aging of people with human immunodeficiency virus (HIV) is a worldwide reality, and age-related conditions, including disability, have also increased. Efforts are being made to search for more specific markers of immune system malfunction, which serve as good predictors of adverse health-related outcomes. Therefore, this study aimed to determine the relationship between the CD4+/CD8+ ratio and functional decline in activities of daily living (ADL). Participants in this longitudinal study underwent a standardized comprehensive geriatric assessment by trained staff, using validated tools. Functional decline in ADL was established by the delta resulting from the subtraction of the score on the Barthel index at T1 minus the score at T0 (baseline). Multivariate linear regression analyses were used to determine the independent relationship between the CD4+/CD8+ ratio and ADL decline. Mean age was 57.9 (standard deviation 6.6; range 50-84 years), and 82.7% were men. Eleven of the 209 participants had disability for ADL at baseline. Multivariate linear regression analysis showed an inverse relationship between the log of CD4+/CD8+ ratio at baseline and the delta of Barthel index even after adjustment for multiple confounders (β = -1.68, 95% confidence interval -3.02 to -0.33; p = .01). A CD4+/CD8+ ratio of <1 predicts the development of functional decline in ADL. This ratio can be a useful marker to identify people at risk of disability and should be considered for the tailored management of older adults with HIV.
