Validation of the Spanish version of the Lawton IADL Scale for its application in elderly people

Resistance exercise to reduce risk of falls in people with Alzheimer's disease: a randomised clinical trial

OBJECTIVES

To evaluate the impact of resistance exercise on the risk of falls, fear of falling, muscle strength, neuropsychiatric symptoms and ability to perform activities of daily living in people with Alzheimer's disease (AD).

DESIGN

Single-blinded randomised controlled trial.

SETTING

Five aged care centres specialising in AD, located in Andalucía, Spain.

PARTICIPANTS

Sixty people diagnosed with AD were assigned at random to either the intervention group (n = 30) or the control group (n = 30).

INTERVENTIONS

The intervention group completed three weekly resistance exercise sessions for 12 weeks, in addition to cognitive training, until completion of the study. The control group undertook cognitive training alone.

MAIN OUTCOME MEASURE

Main outcome measure: risk of falls (Short Physical Performance Battery).

SECONDARY OUTCOMES

muscle strength (hand dynamometry), neuropsychiatric symptoms (Neuropsychiatric Inventory Questionnaire), fear of falling (Activities-Specific Balance Confidence Scale) and ability to perform activities of daily living (Lawton Instrumental Activities of Daily Living Scale).

RESULTS

The analysis demonstrated differences in favour of the intervention group, in both the short and medium term, for risk of falls [post-treatment: mean difference (MD) 1.5, 95% CI of the difference 0.9 to 2.0; 3-month follow up: MD 1.1, 95% CI of the difference 0.6 to 1.6]; fear of falling (post-treatment: MD 1.5, 95% CI of the difference 4.0 to 7.7; 3-month follow up: MD 6.3, 95% CI of the difference 4.3 to 8.2); activities of daily living (post-treatment: MD 0.2, 95% CI of the difference -0.01 to 0.4; 3-month follow up: MD 0.3, 95% CI of the difference 0.01 to 0.5); neuropsychiatric symptoms (post-treatment: MD -2.2, 95% CI of the difference -3.3 to -1.0; 3-month follow up: MD -2.4, 95% CI of the difference -3.7 to -1.2); and dynamometry (post-treatment: MD 3.1, 95% CI of the difference 2.5 to 3.7; 3-month follow up: MD 2.6, 95% CI of the difference 1.9 to 3.3).

CONCLUSION

Resistance exercise effectively reduces the risk of falls, fear of falling and neuropsychiatric symptoms, and improves muscle strength in people with AD in both the short and medium term. CONTRIBUTION OF THE PAPER.

Benefits of an educational intervention on functional capacity in community-dwelling older adults with frailty phenotype: A randomized controlled trial

BACKGROUND

There is an urgent demand for nurses to expand their knowledge and skills in managing frailty in primary care. Frailty is a multifaceted condition that is prevalent among older adults and often leads to reduced functional capacity. Currently, there is a limited understanding of the effectiveness of educational interventions aimed at improving functional capacity among community-dwelling frail older adults in a primary care setting.

OBJECTIVE

This study aimed to evaluate the impact of an educational program on functional capacity among pre-frail and frail older adults living in the community.

DESIGN

A 12-month, multicenter, randomized controlled trial.

SETTINGS

The FRAGSALUD study was conducted across 14 healthcare centers situated within the regions of Cadiz and Malaga, Spain.

PARTICIPANTS

A total of 199 frail/pre-frail community-dwelling older adults (74.2 ± 6.4 years).

METHODS

Participants who met at least one Fried's criteria were assigned to either the control group (n = 90), which received usual healthcare assistance, or the intervention group (n = 109). The 6-month intervention comprised four group sessions and six telephone calls conducted by professional nurses, sport scientists, and nutritionists. This educational program focused on guidelines for physical activity, nutritional habits, cognition, and psychosocial well-being. Functional capacity was assessed using questionnaires for basic (Barthel Index) and instrumental (Lawton and Brody Scale) activities of daily living. All outcome measures were evaluated at baseline, immediately after the intervention (6-month), and six months after the intervention as a follow-up (12-month). Differences in functional capacity (Barthel Index and Lawton and Brody Scale scores) across the three time points were analyzed using Friedman's ANOVA, with Wilcoxon signed-rank test for pairwise comparisons.

RESULTS

At both 6-month and 12-month assessments, the control group showed a statistically significant decline in basic and instrumental activities of daily living compared to the intervention group, which maintained similar levels, preventing this age-related decline.

CONCLUSIONS

The educational intervention, designed for easy implementation within healthcare systems, especially for nurses, successfully maintained levels of functional capacity in basic and instrumental activities of daily living, while the control group experienced a decline in functional capacity during the 12-month follow-up. Thus, educational interventions are encouraged for preserving the functional independence of frail/pre-frail older adults living in the community.

REGISTRATION

This trial was registered at ClinicalTrials.gov (Identifier: NCT05610605) and the first participant was registered in March 2022.

TWEETABLE ABSTRACT

The FRAGSALUD educational intervention prevents the age-related decline in functional independence over 12 months in frail older adults.

Neuropsychological profile of a patient with multiple sclerosis and psychiatric symptoms that masked and delayed the diagnosis. A case report using teleneuropsychology

Objective: Multiple sclerosis (MS) may include not only severe neurological signs and symptoms, but also cognitive and psychiatric disturbances. When psychiatric symptoms precede or are comorbid with MS, it poses a clinical challenge, because it may lead to a mistaken diagnosis of MS as a psychiatric disorder, delaying proper treatment. We describe the neuropsychological profile of a female patient with MS whose diagnosis was delayed due to neuropsychiatric symptoms. Method: A comprehensive analysis of the medical history and the results of a teleneuropsychological assessment of a 36-year-old Mexican woman with a diagnosis of relapsing--remitting MS (RRMS) was performed. Results: The patient indicates a long history of psychotic, anxious, and depressive features years before the first neurological symptom that led to MS going unnoticed for several years. Language, attentional, perceptual, motor, and learning skills were found to be preserved. Short-term memory and spatial orientation problems were identified, with decreased processing speed and executive dysfunction, including working memory and planning deficits. Conclusions: The patient has a non-typical presentation of neuropsychological alterations with cognitive and behavioral symptoms that resemble dorsolateral frontal lobe syndrome. This case study highlights the importance of considering MS in differential diagnosis of patients with psychiatric symptoms, even in the absence of obvious neurological signs.

Comprehensive Gerontological Assessment: An Update on the Concept and Its Evaluation Tools in Latin America and the Caribbean-A Literature Review

In recent decades, Latin America and the Caribbean region have experienced accelerated aging. However, despite the significant progress of gerontology in the region, the number of geriatricians and professionals trained in the field is low; a notable gap in the training related to the assessment of older adults can also be observed. Therefore, in this literature review, we update the concept of Comprehensive Gerontological Assessment (CGA) for its application in the region. We compile the characteristics, validity, and reliability of CGA tools, and their usage in government documents across countries in the region. We also analyze the adaptations made to CGA during the COVID-19 pandemic, and discuss challenges related to CGA administration, academic training, research, innovation, and management. This study is particularly relevant as it proposes lines of action for decision-makers, academics, researchers, university students, and the general community, which will allow for more tailored interventions aimed at meeting the needs of older adults, their families, and caregivers. Such actions will positively impact functionality, autonomy, and quality of life, while promoting healthy, active, and successful aging in the region.

Social and Mental Health Factors Involved in the Severity of Loneliness in Older Individuals in a Spanish Rural Area

Background: Loneliness in older people, especially those living in rural areas, is a phenomenon that has received little attention in research and can have detrimental effects on quality of life. The aim of this study was to evaluate loneliness and the psychosocial factors associated with loneliness in rural Spain, which have been minimally studied. Methods: A cross-sectional study was carried out in a sample of permanently resident older people in the Rincón de Ademuz region (Valencia, Spain), a geographic area with very low population density. Emotional and social loneliness were assessed using the de Jong Gierveld Loneliness Scale. We also assessed whether loneliness is associated with sleep quality, depressive symptoms, and autonomy in basic and instrumental activities of daily living. Results: A total of 108 community-dwelling individuals aged 65 years and older participated in the study out of a total sample of 181. Of them, 30.6% experienced feelings of moderate loneliness, while 2.8% presented severe loneliness. A significant correlation was found between loneliness and age (Rho = 0.28, p = 0.003). Significant differences were also observed between emotional loneliness and gender (p = 0.03) but not between social loneliness and the total score on the de Jong Gierveld Scale. Men experienced more emotional loneliness than women. In the multivariate analyses, significant associations were found between the degree of loneliness and having sons/daughters (p = 0.03; odds ratio [OR] = 0.24; 95% CI 0.06-0.89) and the role of caring for a dependent person (p = 0.002; odds ratio [OR] = 0.05; 95% CI 0.009-0.36) but not living with sons/daughters or the presence of grandchildren. Conclusions: There is a high prevalence of loneliness among older people living in rural areas, which is associated with some social factors. Therefore, nursing care plans should include assessments and interventions to prevent or detect and address loneliness in older people. This study was retrospectively registered in ClinicalTrials on 24 April 2024 with registration number NCT06382181.

[Predictive model and discriminant analysis of the development of dementia in patients with delirium in the emergency department]

OBJECTIVE

The main aim of our study is to know the sociodemographic, clinical, analytical, and functional variables that predict the probability of developing dementia in patients with delirium who attend the emergency room.

METHOD

All patients with delirium (n=45) from the emergency room who were admitted to the Geriatrics service of the General University Hospital of Ciudad Real (HGUCR) in 2016-2018 and met the inclusion and exclusion criteria were included. Subsequently, we ran a bivariate and multivariate analysis of the variables that predicted a diagnosis of dementia at six months and a discriminant analysis.

RESULTS

15.6% of patients presented dementia at six months of follow-up, 22.2% had developed cognitive impairment. We conducted a multivariate model (R2 Nagelkerke 0.459) for the probability of developing dementia, with elevated heart rate being the most crucial variable (OR=11.5). The model could excluded dementia with 100% accuracy. Finally, we achieved a discriminant function capable of correctly classifying 95.6% of the cases. It included the following variables of influence: pH, Lawton Brody index, calcium, urea, and heart rate.

CONCLUSIONS

A few clinical and analytical variables that are easily detectable in the emergency room, especially tachycardia, could help us better identify those patients with delirium at higher risk of developing dementia, as well as formulate hypotheses about the variables involved in the development of dementia in patients with delirium.

Performance of instrumental activities of daily living in patients with haemophilic arthropathy. A cross-sectional cohort study

BACKGROUND

The development of haemophilic arthropathy causes joint damage that leads to functional impairment that limits the performance of activities in patients with haemophilia. The aim was to identify the best predictive model for performing instrumental activities of daily living in adult patients with haemophilia arthropathy.

METHODS

Cross-sectional cohort study. 102 patients were recruited. The dependent variable was the performance of instrumental activities of daily living (Lawton and Brody scale). The dependence on the performance of activities of daily living was the dependent endpoint (Barthel scale). The secondary variables were joint damage (Hemophilia Joint Health Score), pain intensity, and clinical, anthropometric, and sociodemographic variables.

RESULTS

The degree of dependence, joint damage, pain intensity, and marital status (Cp = 5.60) were the variables that best explain the variability in the performance of instrumental activities of daily living (R2 adj = 0.51). Loss of predictive capacity is acceptable with good mean internal (R2 mean = 0.40) and external (R2-r2 = 0.09) validation. According to the predictive pattern obtained, patients with haemophilia, who were married, without joint pain or damage, and independent in their day-to-day lives, had a score of 7.91 points (95% CI: 7.42; 8.39) in the performance of instrumental activities of daily living.

CONCLUSIONS

The predictive model for the functional capacity of instrumental activities of daily living in haemophilia patients encompasses factors such as level of autonomy, joint impairment, pain severity, and marital status. Notably, despite the presence of joint damage, individuals with haemophilia exhibit a significant level of independence in carrying out both basic daily tasks and instrumental activities of daily living.

Evidence for the reliability and validity of a Spanish translation of the Medication Management Ability Assessment administered via tele-assessment

We translated the Medication Management Ability Assessment (MMAA) from English to Spanish for use via tele-assessment and examined its reliability and validity. Following International Test Commission Guidelines for Translating and Adapting Tests, we used translation/back-translation and a small focus group (n = 6) to adapt a Spanish version of the MMAA. Eighty-six Spanish-speaking adults completed the adapted MMAA via tele-assessment at baseline and at a two-week follow-up visit. Participants also completed several self-report and performance-based cognitive and functional measures. The internal consistency of the MMAA was excellent (standardized Cronbach's α = 0.90). Performance-based functional assessments (PBFAs) and objective cognition were positively associated with the MMAA at small to medium effect sizes. Self-report measures of daily function and cognition, measures of health literacy, and estimates of premorbid intellectual functioning were not significantly associated with MMAA performance. The test-retest reliability of the MMAA was good (CCC = 0.73, 95% CI [0.62, 0.81]; rs = 0.37, p < 0.001) and demonstrated a small practice effect (Cohen's d = 0.36, p = 0.001). Preliminary evidence for the construct validity of a Spanish-language MMAA administered via tele-assessment further expands the potential clinical utility of PBFAs in culturally diverse, Spanish-speaking populations.

Latent profile analysis of depression and its influencing factors in older adults raising grandchildren in China

OBJECTIVE

To explore the latent profile of depression in older adults raising grandchildren in China, and to analyze the differences in the characteristics of the different profiles of the population and the factors influencing them.

METHODS

This study utilized the 2018 China Health and Retirement Longitudinal Study (CHARLS). Through a cross-sectional study, the latent profile analysis was used to analyze the potential classification of depression among older adults raising grandchildren, and using ordered multi-categorical logistic regression analyses to assess the effects of each factor on their different classifications.

RESULTS

The 1271 older adults raising grandchildren with depression symptoms were divided into three categories: low-level depression (55.4%), moderate-level depression (31.2%), and high-level depression (13.4%). Ordered multi-categorical Logistic results showed: Gender, marital status, pension insurance, physical health status, life satisfaction, and IADL were predictors of latent profile classification of depression symptoms in older adults raising grandchildren (P < 0.05).

CONCLUSIONS

In the future of primary care, it will be more meaningful to provide targeted interventions for different subgroups of depression in older adults raising grandchildren.

Effects of a dual intervention (motor and virtual reality-based cognitive) on cognition in patients with mild cognitive impairment: a single-blind, randomized controlled trial

BACKGROUND

The increase in cases of mild cognitive impairment (MCI) underlines the urgency of finding effective methods to slow its progression. Given the limited effectiveness of current pharmacological options to prevent or treat the early stages of this deterioration, non-pharmacological alternatives are especially relevant.

OBJECTIVE

To assess the effectiveness of a cognitive-motor intervention based on immersive virtual reality (VR) that simulates an activity of daily living (ADL) on cognitive functions and its impact on depression and the ability to perform such activities in patients with MCI.

METHODS

Thirty-four older adults (men, women) with MCI were randomized to the experimental group (n = 17; 75.41 ± 5.76) or control (n = 17; 77.35 ± 6.75) group. Both groups received motor training, through aerobic, balance and resistance activities in group. Subsequently, the experimental group received cognitive training based on VR, while the control group received traditional cognitive training. Cognitive functions, depression, and the ability to perform activities of daily living (ADLs) were assessed using the Spanish versions of the Montreal Cognitive Assessment (MoCA-S), the Short Geriatric Depression Scale (SGDS-S), and the of Instrumental Activities of Daily Living (IADL-S) before and after 6-week intervention (a total of twelve 40-minutes sessions).

RESULTS

Between groups comparison did not reveal significant differences in either cognitive function or geriatric depression. The intragroup effect of cognitive function and geriatric depression was significant in both groups (p < 0.001), with large effect sizes. There was no statistically significant improvement in any of the groups when evaluating their performance in ADLs (control, p = 0.28; experimental, p = 0.46) as expected. The completion rate in the experimental group was higher (82.35%) compared to the control group (70.59%). Likewise, participants in the experimental group reached a higher level of difficulty in the application and needed less time to complete the task at each level.

CONCLUSIONS

The application of a dual intervention, through motor training prior to a cognitive task based on Immersive VR was shown to be a beneficial non-pharmacological strategy to improve cognitive functions and reduce depression in patients with MCI. Similarly, the control group benefited from such dual intervention with statistically significant improvements.

The Role of Functional Deficits, Depression, and Cognitive Symptoms in the Perceived Loneliness of Older Adults in Mexico City

The world is aging and experiencing loneliness. Functional impairment in instrumental activities of daily living (IADL) in older people (OP) with mild neurocognitive disorder (MNCD) predicts loneliness. After the pandemic, there was an increase in perceived loneliness. We explored the association between loneliness, depression, deficits in IADL, and cognitive symptoms among OP. From February to December 2023, using a cross-sectional design, we interviewed probable cases with mild cognitive impairment and caregivers in two public facilities. We administered the UCLA Loneliness Scale v3, Lawton IADL Scale, Mini-Mental State Examination (MMSE), and Yesavage's Geriatric Depression Scale. Samples were matched: 85 per group, 82.4% were women, married (52.95%), and mean age of 69.17 (±6.93) years. In our study, 30% displayed moderate to high levels of perceived loneliness. Multivariate analysis showed loneliness was associated with depression, low levels of IADL, and older age, but not with cognitive symptoms, which explained 22% of the total variance (F 165) = 16.99, (p < 0.001). Targeting symptoms and behaviors that could be modified (i.e., depression and functionality) can improve feelings of perceived loneliness and have an impact on morbidity and mortality with which it is associated.

[Improving quality of life in older adults with the decline syndrome: The role of occupational therapy in primary care]

OBJECTIVE

To evaluate the effect of an occupational therapy intervention in users recently diagnosed with the decline syndrome, who have experienced a decrease in the Barthel and/or Lawton index in the last month and susceptible to improvement based on medical opinion.

DESIGN

Non-controlled, quasi-experimental longitudinal study. A pre-post intervention.

LOCATION

Sant Hipòlit de Voltregà health centre. Osona, Barcelona.

PARTICIPANTS

Patients referred by the centre's primary care nursing, social work or medical staff with a recent diagnosis of decline syndrome who may benefit from the intervention of an occupational therapy professional.

INTERVENTION

Following the initial assessment visit, four training sessions were conducted to improve functional independence, mobility and adaptation of the home environment, providing training to primary caregivers.

MAIN MEASUREMENTS

Patient autonomy was assessed using the Barthel and Lawton scales, quality of life using the EuroQol questionnaire (EQ-5D) and home suitability using the home suitability assessment questionnaire.

RESULTS

Improvements were observed in autonomy in activities of daily living (p=0.003), mobility (p=0.001) and housing adaptation (p<0.001). The level of anxiety/depression was reduced (p=0.028), and the mean health status score increased markedly (p<0.001).

CONCLUSIONS

This study highlights the improvement in the quality of life and autonomy in the basic activities of daily living for individuals receiving occupational therapy, emphasizing the need for home adaptation and family support.

Analysis of the life course effects of the disability dilemma among rural older adults in China

Objective

To analyse whether the accumulation of early adverse experiences among individuals of different generations has an impact on disabilities and evaluate the cumulative effects of disadvantages in rural older adults in China.

Methods

A Binary Logit Model was used to analyse the life course effects of the disability dilemma among rural older adults.

Results

Regarding Activities of Daily Life (ADLs), there was no significant difference between older adults that experienced 1 adverse events and the control group. The probability of older adults experiencing difficulties in 2, 3, 4, or more types of ADLs was 1.486 times, 2.173 times, and 3.048 times higher than that of the control group, respectively. Regarding Instrumental Activities of Daily Life (IADLs), there was no significant difference between the population that experienced 1 or 2 adverse events and the control group. The probability of experiencing difficulties in 3, 4, or more types of IADLs was 1.527 times and 1.937 times higher than that of the control group, respectively. Early adverse events had a cumulative disadvantageous effect on disability in older adults. The longer the duration of adverse experiences, the higher the risk of disability in old age. Education had a significant mitigating effect on health risks.

Conclusion

Pay attention to early factors in the life course, strengthen the promotion of health prevention concepts, and pay attention to the moderating and relieving effects of education on health. We should also gradually improve the rural disability care system and family health security capabilities in China's rural areas.

Pre-Fracture Functional Status and Early Functional Recovery are Significant Predictors of Instrumental Activities of Daily Living After Hip Fracture: A Prospective Cohort Study

Introduction

Although the overall quality of medicine has improved in recent decades, the functional capacity in many hip fracture patients remains insufficient. The goal of the present study was to identify significant predictors of Instrumental Activities of Daily Living (IADL) measured by the Lawton-Brody scale at 3- and 6-month follow-up in patients with hip fractures admitted to a hospital.

Methods

This observational cohort study included 191 patients with acute hip fractures. IADL was measured at baseline and after 3 and 6 months using the Lawton-Brody scale. Multivariable logistic regression analysis was carried out using pre-fracture functional status, sociodemographic variables, hand grip strength (HGS), surgical procedure, complications, and length of hospital stay, Short Physical Performance Battery, and Barthel Index (BI) on the fifth postoperative day as potential predictors for IADL after a hip fracture surgery.

Results

The mean age of the participants was 80.3 ± 6.8 years, and 77.0% of our cohort were women. Multivariate regression analysis revealed that pre-fracture functional status and early functional recovery were independent predictors of IADL after hip fracture surgery.

Conclusions

Clinicians should take steps to improve functional outcomes by changing how patients are rehabilitated in the first days after hip fracture surgery, especially for the group of patients with a lower functional status before the fracture.

An assessment of the content and properties of extended and instrumental activities of daily living scales: a systematic review

PURPOSE

We performed a systematic review to assess the psychometric properties of extended Activities of Daily Living (eADL) scales.

MATERIALS AND METHODS

Articles assessing eADL scales' properties were retrieved by searching multidisciplinary databases, and reference screening. Data on the following properties were extracted: validity, reliability, responsiveness, and internal consistency. The COSMIN (Consensus-based Standards for the selection of health status Measurement Instruments) risk of bias checklists are used to assess the quality of included articles. All aspects were performed by two independent researchers.

RESULTS

Of 245 titles, 26 articles were eligible, comprising 15 different eADL scales. The Lawton scale had the most papers describing properties, while the Performance-based Instrumental Activities of Daily Living received the highest COSMIN rating. Properties most often assessed were convergent validity and reliability, no articles assessed all COSMIN properties. The COSMIN assessment rated 43% of the properties as 'positive', 31% 'doubtful' and 26% 'inadequate'. Only Lawton was assessed in more than one paper, available data suggest that this scale has excellent reliability, construct validity, internal consistency, and medium criterion validity.

CONCLUSION

Despite their common use, there are limited data on the properties of eADL scales. Where data are available there are potential methodological issues in the studies.

Data-driven clustering approach to identify novel clusters of high cognitive impairment risk among Chinese community-dwelling elderly people with normal cognition: A national cohort study

Background

Cognitive impairment is a highly heterogeneous disorder that necessitates further investigation into the distinct characteristics of populations at varying risk levels of cognitive impairment. Using a large-scale registry cohort of elderly individuals, we applied a data-driven approach to identify novel clusters based on diverse sociodemographic features.

Methods

A prospective cohort of 6398 elderly people from the Chinese Longitudinal Healthy Longevity Survey, followed between 2008-14, was used to develop and validate the model. Participants were aged ≥60 years, community-dwelling, and the Chinese version of the Mini-Mental State Examination (MMSE) score ≥18 were included. Sixty-nine sociodemographic features were included in the analysis. The total population was divided into two-thirds for the derivation cohort (n = 4265) and one-third for the validation cohort (n = 2133). In the derivation cohort, an unsupervised Gaussian mixture model was applied to categorise participants into distinct clusters. A classifier was developed based on the most important 10 factors and was applied to categorise participants into their corresponding clusters in a validation cohort. The difference in the three-year risk of cognitive impairment was compared across the clusters.

Results

We identified four clusters with distinct features in the derivation cohort. Cluster 1 was associated with the worst life independence, longest sleep duration, and the oldest age. Cluster 2 demonstrated the highest loneliness, characterised by non-marital status and living alone. Cluster 3 was characterised by the lowest sense of loneliness and the highest proportions in marital status and family co-residence. Cluster 4 demonstrated heightened engagement in exercise and leisure activity, along with independent decision-making, hygiene, and a diverse diet. In comparison to Cluster 4, Cluster 1 exhibited the highest three-year cognitive impairment risk (adjusted odds ratio (aOR) = 3.31; 95% confidence interval (CI) = 1.81-6.05), followed by Cluster 2 and Cluster 3 after adjustment for baseline MMSE, residence, sex, age, years of education, drinking, smoking, hypertension, diabetes, heart disease and stroke or cardiovascular diseases.

Conclusions

A data-driven approach can be instrumental in identifying individuals at high risk of cognitive impairment among cognitively normal elderly populations. Based on various sociodemographic features, these clusters can suggest individualised intervention plans.

Hearing and Balance in Healthy Aging Project: Characterization of Hearing, Balance, and Other Associated Disorders in Three Population Groups Aged 55 and Over

INTRODUCTION

Active aging emphasizes optimizing health and participation for a better quality of life as people age. This paper explores the significant impact of hearing loss and balance disorders on the elderly. Age-related hearing loss is thought to contribute to communication breakdown and cognitive dysfunctions. The "hearing and balance in healthy aging" project focuses on early detection, mitigation, and advocacy. Objectives include exploring epidemiological traits, evaluating overall well-being impact, proving positive intervention effects, and advocating societal care for the elderly with hearing loss and balance disorders, aiming to reduce their broader impact on cognition, independence, and sociability.

METHODS

This study is observational, prospective study. Subjects over 55 years old with a follow-up every year or every 2 years were divided into three groups, according to their hearing and balance: within the normal range (group A), detected and not treated (group B), and detected and treated (group C). At each visit, they underwent a series of tests or questionnaires, evaluating different areas: hearing, balance, cognition, depression, dependence, tinnitus, loneliness, health.

RESULTS

A total of 710 patients were included in the study. The distribution of patients was as follows: group A - 210 patients, group B - 302 patients, and group C - 198 patients. Significant differences were found between the three groups related to age, sex, educational level, bilingualism, and work activity. In group C, there was a higher percentage of males, older than in groups A and B, and the percentage of individuals with a university education was lower (28%), as was the rate of bilingualism (23%). In terms of hearing, significant differences were found in the three groups in the mean PTA, speech discrimination in quiet, and the HINT test, with worse results for group C. Only patients in group C presented a perception of hearing impairment, and the handicap caused by hearing impairment worsened from group A to C. Concerning balance, both tests performed (TuGT and DHI) revealed increased difficulty in maintaining autonomous walking from group A to C, which, again, exhibited the worst results, with statistically significant differences across the group. Analysis about cognition revealed significant differences in DSST questionnaires and in TMT scores, where group C had the worst scores. In HUI3 questionnaire scores, the differences between each and every group were statistically significant, with group C showing moderate disability.

CONCLUSION

This extensive analysis, encompassing a considerable number of subjects, reveals significant findings that have important implications for the early prevention of hearing loss and its consequent consequences. At the same time, these data represent an initial exploration, which raises the need for in-depth examinations of additional factors and longer follow-up to continue contributing insights and knowledge for a healthy aging.

Predicting progression of cognitive decline to dementia using dyadic patterns of subjective reporting: evidence from the CompAS longitudinal study

Objective

To analyze the validity of self and informant reports, depressive symptomatology, and some sociodemographic variables to predict the risk of cognitive decline at different follow-up times.

Methods

A total of 337 participants over 50 years of age included in the CompAS and classified as Cognitively Unimpaired (CU), Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI) groups were assessed at baseline and three follow-ups. A short version of the QAM was administered to assess the severity of subjective cognitive complaints (SCCs), and the GDS-15 was used to evaluate the depressive symptoms. At each follow-up assessment, participants were reclassified according to the stability, regression or progression of their conditions. Logistic regression analysis was used to predict which CU, SCD and MCI participants would remain stable, regress or progress at a 3rd follow-up by using self- and informant-reported complaints, depressive symptomatology, age and education at baseline and 2nd follow-ups as the predictive variables.

Results

Overall, self-reported complaints predicted progression between the asymptomatic and presymptomatic stages. As the objective deterioration increased, i.e., when SCD progressed to MCI or dementia, the SCCs reported by informants proved the best predictors of progression. Depressive symptomatology was also a predictor of progression from CU to SCD and from SCD to MCI.

Conclusion

A late increase in self-reported complaints make valid estimates to predict subjective decline at asymptomatic stages. However, an early increase in complaints reported by informants was more accurate in predicting objective decline from asymptomatic stages. Both, early and late decrease in self-reported complaints successfully predict dementia from prodromic stage. Only late decrease in self-reported complaints predict reversion from prodromic and pre-symptomatic stages.

Effectiveness of a randomized intervention by a geriatric team in frail hospital inpatients in non-geriatric settings: FRAILCLINIC project

BACKGROUND

Little research has been undertaken on the benefits of frailty management within different hospital settings. The objective of this study is to provide evidence on the viability and effectiveness of frailty management in non-geriatric hospital settings on mortality and functional decline after discharge.

METHODS

Data from the FRAILCLINIC (NCT02643069) study were used. FRAILCLINIC is a randomized controlled trial developed in non-geriatric hospital inpatient settings (emergency room, cardiology and surgery) from Spain (2), Italy (2) and the United Kingdom (1). Inpatients must met frailty criteria (according to the Frailty Phenotype and/or FRAIL scale), ≥75 years old. The control group (CG) received usual care. The intervention group (IG) received comprehensive geriatric assessment (CGA) and a coordinated intervention consisting in recommendations to the treating physician about polypharmacy, delirium, falls, nutrition and physical exercise plus a discharge plan. The main outcomes included functional decline (worsening ≥5 points in Barthel Index) and mortality at 3 months. We used multivariate logistic regression models adjusted by age, gender and the Charlson index. Intention-to-treat (ITT) and per-protocol (PP) analyses were used.

RESULTS

Eight hundred twenty one participants (IG: 416; mean age 83.00 ± 4.91; 51.44% women; CG: 405; mean age 82.46 ± 6.03; 52.35% women) were included. In the IG, 77.16% of the participants followed the geriatric team's recommendations as implemented by the treating physicians. The intervention showed a benefit on functional decline and mortality [OR: 0.67(0.47-0.96), P-value 0.027 and 0.29(0.14-0.57), P-value < 0.001, respectively) when fully followed by the treating physician. A trend to benefit (close to statistical significance) in functional decline and mortality were also observed when any of the recommendations were not followed [OR (95% CI): 0.72 (0.51-1.01), P-value: 0.055; and 0.64 (0.37-1.10), P-value: 0.105, respectively].

CONCLUSIONS

An individualized intervention in frail in-patients reduces the risk of functional deterioration and mortality at 3 months of follow-up when a care management plan is designed and followed.

Attentional Resources and Independence in Basic and Instrumental Activities of Daily Living in Individuals with Intellectual Disabilities

The relationship between attentional resources and functionality in individuals with intellectual disabilities (IDs) is clinically relevant. This study aimed to examine the possible relationship between the degree of ID and attentional resources, and to evaluate whether attentional resources predict the performance of basic and instrumental activities of daily living (ADL) in individuals with mild and moderate ID. This study, which employed a descriptive, cross-sectional, observational design, was conducted between July 2019 and May 2020. The sample consisted of 166 individuals divided into three groups: moderate ID, mild ID, and those without ID. These groups were compared for attentional functions (p < 0.001), obtaining an effect size ranging from medium to large. The results indicated that 40% of the variance in basic ADL performance was explained by the age of the participants, degree of disability, and sustained attention in individuals with ID. Additionally, 64% of the variance in instrumental ADL performance was explained by sustained, divided, and executive attention. Therefore, attentional resources appear to be associated with the performance of basic and instrumental ADL in individuals with mild and moderate ID.

Measurement properties of the Spanish COPM in older adult rehabilitation inpatients

AIMS

To analyse the measurement properties of the Spanish version of the COPM (Canadian Occupational Performance Measure) in older adult rehabilitation inpatients.

METHOD

A sample of 172 users from 17 inpatient care facilities for older adults (47% nursing homes) participated in a quantitative prospective study. We examined validity by correlating the COPM with the Barthel Index (BI), the Lawton Instrumental Activities of Daily Living scale (IADL), the EuroQol-five domains-three level questionnaire (EQ-5D-3L), and the Client-Centred Rehabilitation Questionnaire (CCRQ) and by examining associations with demographic variables. Reliability was evaluated through test-retest and responsiveness through differences in change scores in two types of care facilities.

RESULTS

Participants prioritised 637 occupational performance problems, mainly in the area of self-care (70.5%). The COPM scale scores were significantly correlated with BI, IADL, EQ-5D-3L (except the pain dimension), and CCRQ (except the family involvement and continuity dimensions). COPM scores did not show statistically significant differences concerning educational level. Regarding reliability, high test-retest correlations were obtained (>.80). Nursing home users showed less responsiveness to rehabilitation than other users (change score < 2 vs. > 2 points).

CONCLUSION AND SIGNIFICANCE

The Spanish COPM provides satisfactory measurement properties as a client-centred instrument in older adult rehabilitation inpatient.

Predictive variables of depressive symptoms and anxiety in older adults from primary care: a cross-sectional observational study

BACKGROUND

By 2050, the number of people aged 60 years and older will have doubled worldwide and the most common mental disorders in this age group are currently depressive symptoms and anxiety. This study aimed to analyze the Basic and Instrumental Activities of Daily Living (BADLs and IADLs, respectively) in older adults; socio-demographic, clinical, lifestyle, and environmental variables; and cognitive impairment related to the appearance of depressive symptoms and anxiety.

MATERIAL AND METHODS

A cross-sectional observational study was conducted with 327 participants aged ≥65 years in primary care. The variables were Yesavage's Geriatric Depression Scale, the Goldberg Anxiety Subscale, socio-demographic, clinical, lifestyle, environmental variables, BADLs, IADLs, and the Spanish version of the Mini-Mental State Examination.

RESULTS

An analysis of variance was carried out for the predictive multiple linear regression models. '≥ 1 chronic pathology' and 'low dependency' in BADL are negatively associated with anxiety, while 'physical activity' and 'low dependency' in BADL are associated with positive factors for depressive symptoms.

CONCLUSIONS

Predictor variables could improve the early detection of anxiety and depressive symptoms by general practitioners and serve as a basis for future studies and personalised-adapted cognitive stimulation programs.

Benzodiazepine Consumption, Functionality, Cognition, and Somnolence in Older Adults at a Tertiary Care Psychiatric Hospital in Mexico City

BACKGROUND

The aging population in Mexico, particularly those aged 60 and above, faces challenges in healthcare, including potentially inappropriate prescriptions of benzodiazepines. Physiological changes in older adults make precise drug prescriptions crucial.

OBJECTIVE

This study aims to evaluate and compare functionality, cognition, and daytime somnolence in older adults using benzodiazepines versus non-users. Additionally, it outlines the demographic and clinical characteristics of both groups.

METHODS

A cross-sectional study enrolled 162 participants aged 60 and above, categorized as benzodiazepine consumers or non-consumers. Assessment tools included Lawton's Index, Montreal Cognitive Assessment, Epworth Sleepiness Scale, and Benzodiazepine Dependence Questionnaire. Statistical analysis employed t-tests and chi-square tests.

RESULTS

Benzodiazepine users (n=81) exhibited lower cognitive scores, increased sleepiness, and reduced daily living activities compared to non-users (n=81). Demographically, BZD users had lower education levels.

CONCLUSION

Benzodiazepine use in older adults is associated with cognitive decline, daytime somnolence, and functional limitations, emphasizing the need for cautious prescription practices and continual monitoring. This study contributes insights into the impact of benzodiazepines on the cognitive health of older adults in Mexico.

Gait speed according to cognitive status in older adults: a cross-sectional study in a resource-limited country

OBJECTIVE

We aimed to investigate the association between gait speed and cognitive status in outpatient older adults from a resource-limited setting in Peru.

METHODS

We performed a cross-sectional study including older adults aged ≥60 years attending a geriatrics outpatient clinic between July 2017 and February 2020. Gait speed was measured over a 10-meters distance without considering the first and last meter traveled. Cognitive status was assessed through the Short Portable Mental Status Questionnaire (SPMSQ) and the Mini-Mental State Examination (MMSE). We used a multivariate binomial logistic regression to conduct both an epidemiological and fully adjusted models.

RESULTS

We included 519 older adults (mean age: 75 years; IQR = 10), of whom 95 (18.3%) and 151 (31.5%) were cognitively impaired according to the SPMSQ and MMSE, respectively. Gait speed was slower among patients with poorer cognitive status as assessed by both tools (p < 0.001). Malnutrition (PR: 1.74; CI: 1.45-2.08) and functional dependency (PR: 4.35; CI: 2.68-7.08) were associated with a greater prevalence of cognitive impairment according to the SPMSQ, whereas a faster gait speed (PR: 0.27, CI: 0.14-0.52) and longer years of education (PR: 0.83, CI: 0.77-0.88) were associated with a less prevalence.

CONCLUSIONS

Slower gait speed was associated with poorer cognitive status in outpatient older adults. Gait speed may be a complementary tool in the cognitive assessment of older adults from resource-limited settings.

The Association between Executive Function and Performing Instrumental Daily Activities in People with Intellectual Disabilities

Institutionalized individuals with intellectual disabilities have few opportunities to participate in instrumental activities of daily living (IADLs), which probably affects higher cognitive functions, or vice versa. The objectives of this study were to evaluate the possible difference in the ability to perform IADLs and executive functioning between individuals with and without intellectual disabilities and to determine if executive functions are associated with the performance of IADLs in people with intellectual disabilities. This was a multi-center cross-sectional study, conducted between July 2019 and May 2020. Participants with intellectual disabilities were recruited from four centers for people with intellectual disabilities. Adults without these disabilities were gathered from several community centers. The sample consisted of 90 individuals with moderate intellectual disabilities and 79 individuals with no intellectual disability. Executive functions were evaluated using the Wechsler Adult Intelligence Scale-WAIS-IV, the INECO Frontal Screening test, the Semantic Verbal Fluency Test, and the Behavioural Assessment of the Dysexecutive Syndrome-BADS-Scale. The performance of the IADLs was assessed by the Lawton and Brody Scale. The results showed that the higher the function in instrumental activities, the lower the impairment of executive functions. Executive functions accounted for 81% of the total variance in the ability to perform the IADLs. In conclusion, individuals with moderate intellectual disabilities demonstrated limitations in executing the IADLs, which were partially associated with low performance in executive functions. This information could help in the development of evidence-based intervention programs and facilitate the formulation of appropriate support strategies to enhance participation in these activities.

Fear of Falling Score Is a Predictor of Falls in Community-Dwelling Pre-Frail and Frail Older People

Identifying frail older people at risk of falling is a priority in order to apply preventive strategies. This cross-sectional study included community-dwelling pre-frail and frail people (Fried's criteria) aged 70 years and older to assess the prevalence of falls and identify screening strategies based on comprehensive geriatric assessments to detect an increased risk of falling and recurrent falling in community-dwelling frail and pre-frail old people. Of the 229 participants, 121 (54.9%) had fallen in the previous 12 months, and 20 of these (16.5%) were recurrent fallers (≥2 falls). A score of 20 points or more on the Falls Efficacy Scale International was predictive of falling (area under the receiver-operating characteristics curve 0.67, 95% confidence interval: 0.61-0.74, p < 0.001) with a sensitivity of 51.7% and a specificity of 73.9%. Polypharmacy, Short Physical Performance Battery score of 8 points or less, and Falls Efficacy Scale International score of 20 points or more show an area under the curve of 0.78 (95% confidence interval: 0.67-0.89, p < 0.001) for recurrent falling.

Lawton's Instrumental Activities of Daily Living for Greek-Speaking Adults with Cognitive Impairment: A Psychometric Evaluation Study with Additional Receiver Operating Characteristic Curve Analysis

One of the components of a dementia diagnosis is the assessment of functional abilities. These abilities are measured via screeners, such as the Instrumental Activities of Daily Living (IADL) scale. The IADL scale is a valid tool that has been adapted in many languages. This study aimed to provide a cut-off point and validate the Greek version of the IADL scale in populations with cognitive impairment. IADL data were collected from 132 individuals: 24 PD patients, 24 Parkinson's disease dementia (PDD) patients, and 24 AD patients. The remaining 60 participants were cognitive healthy adults (CHAs). The CHA group and the PD group served as the cognitively unimpaired group (CUG), while the PDD and AD groups served as the cognitively impaired group (CIG). Additionally, the MMSE, the AMTS, the Clock Drawing Test CDT, the Arizona Battery for Communication Disorders of Dementia (ABCD), the NPI, and the GDS-15 were administered to the participants. Statistically significant differences in the IADL scores were exhibited between all subgroups. The IADL scale showed high internal consistency (Cronbach's alpha = 0.890). A threshold equal to 6.00 (AUC = 0.888, p < 0.001) was estimated between the CUG and the CIG. Significant positive correlations were observed between IADL and MMSE (r = 0.764, p < 0.001), IADL and AMTS (r = 0.724, p < 0.001), IADL and ABCD (r = 0.702, p < 0.001), and IADL and CDT (r = 0.627, p < 0.001) results. Given the obtained results, the IADL scale is a valid tool for clinical use with high reliability and sensitivity. Also, the IADL scale is a valuable instrument for screening functional abilities associated with cognitive impairment.

Are Patient-Reported Outcome Measures for Distal Radius Fractures Validated for Spanish and Culture? A Systematic Review

PURPOSE

Patient-reported outcome measures (PROMs) are used commonly to assess function to direct treatment and evaluate outcomes for patients with distal radius fractures. Most PROMs have been developed and validated in English with minimal report of the demographics of patients studied. The validity of applying these PROMs among Spanish-speaking patients is unknown. The purpose of this study was to evaluate the quality and psychometric properties of Spanish-language adaptations of PROMs for distal radius fractures.

METHODS

We conducted a systematic review to identify published studies of adaptations of Spanish-language PROMs evaluating patients with distal radius fractures. We evaluated the methodologic quality of the adaptation and validation using Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures, Quality Criteria for Psychometric Properties of Health Status Questionnaire, and the Consensus-based Standards for the Selection of Health Measurement Instruments Checklist for Cross-Cultural Validity. The level of evidence was evaluated based upon prior methodology.

RESULTS

Five instruments reported in eight studies were included: the Patient-Rated Wrist Evaluation (PRWE), Disability of Arm Shoulder and Hand, Upper Limb Functional Index, Lawton Instrumental Activities of Daily Living Scale, and Short Musculoskeletal Function Assessment. The PRWE was the most frequently included PROM. No study followed all six processes for adaptation or assessed all measurement properties. No study demonstrated the completion of more than eight of the 14 aspects of cross-cultural validity. The PRWE had moderate evidence to support half of the domains of measurement properties evaluating the level of evidence.

CONCLUSIONS

None of the five instruments identified received a good rating on all three checklists. Only the PWRE demonstrated moderate evidence on half of the measurement domains.

CLINICAL RELEVANCE

Given the lack of strong evidence to support the quality of these instruments, we recommend adaptation and testing of PROMs for this population before use. Currently, PROMs in Spanish-speaking patients should be used with caution so as not to perpetuate health care disparities.

Effects of High-Intensity Functional Training (HIFT) on the Functional Capacity, Frailty, and Physical Condition of Older Adults with Mild Cognitive Impairment: A Blind Randomized Controlled Clinical Trial

Physical exercise has been established as an intervention in the integral approach for the physical, functional, and social health of older adults. The objective of this study was to determine the effects of a high-intensity functional training (HIFT) program on the physical condition and functional capacity of an elderly Colombian population with mild cognitive impairment. This research corresponds to a blind randomized controlled clinical trial. A total of 169 men and women aged over 65 years were evaluated and distributed in two groups: the experimental group that received a 12-week HIFT intervention (n = 82) and the control group (n = 87) that received general recommendations on the benefits of physical exercise. The outcome variables included physical condition, assessed using the Senior Fitness battery (SNB); Fried's frailty phenotype was applied, and gait and balance were assessed using the Tinetti scale. For the functional variables, activities of daily living, instrumental activities of daily living, and advanced activities of daily living were evaluated. All variables were measured pre- and post-intervention. Statistically significant improvements were observed in the IG for gait stability and balance (p < 0.001), as well as for independence in activities of daily living (p = 0.003), and instrumental and advanced activities (p < 0.001). Likewise, greater functionality was found when assessed with the SNB (p < 0.001), except for upper limb strength. The frailty classification did not show changes post-intervention (p = 0.170) nor in the group x time interaction. MANCOVA analysis showed that regardless of gender, health level, age, BMI, cognition, and health level, the HIFT intervention produced better results in functional capacity, balance, and gait (F = 0.173, p < 0.001, Wilks' λ = 88.231).

Longitudinal Changes in Dual Decline in Memory and Gait Speed Association with Instrumental Activities of Daily Living: Findings from the National Social Life, Health, and Aging Project

Objective: We investigated the association between dual decline (DD) (loss of memory and gait speed) and the instrumental activities of daily living (IADL) degeneration in older adults. Methods: Data were drawn from the National Social Life, Health, and Aging Project (NSHAP) reflecting changes over 5 years. This study used the NSHAP data set wave 2 (2010-2011, N = 3196) and wave 3 (2015-2016, N = 4377). Results: Data from 1640 participants were retrieved. There were 601 people with DD and 1039 people without-DD. The DD group had a 28.4% (95% CI = 1.013-1.626) greater risk of degrading in IADL than the without-DD group (odds ratio = 1.284, p < .05). Conclusion: Current research can be used when establishing intervention programs or policies that can prevent IADL degradation through simple memory training and walking activities for older adults living in the community.

The influence of meaningful activities in the quality of life and functional autonomy of adults with intellectual disability: A prospective study during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic might negatively impact the quality of life and functional autonomy of Spanish adults with intellectual disability, and meaningful activities could prevent this negative progression.

METHODS

This is a prospective cohort study in Spanish adults with intellectual disability during the COVID-19 pandemic. Quality of life, functional autonomy and functional independence were measured. The meaningful activities studied were structured-leisure, community self-management, and occupational and physical activities.

RESULTS

Seventy-three participants were included in the study. Quality of life and functional autonomy significantly deteriorated during the COVID-19 pandemic (all p > .001). Greater participation in community self-management activities before COVID-19 was associated with less detriment to quality of life (ß = -.312; p = .008), while greater participation in occupational and physical activities was associated with less detriment to the performance of instrumental activities (ß = -.317; p = .016; and ß = -.285; p = .030, respectively).

CONCLUSION

People with intellectual disability living in residential homes experienced a decrease in their quality of life and functional autonomy during the COVID-19 pandemic. Their involvement in community self-management activities and physical and occupational activities before the pandemic had preventive effects on the detriment to the quality of life and functional autonomy.

Factors related to early readmissions after acute heart failure: a nested case-control study

AIMS

To describe the main characteristics of patients who were readmitted to hospital within 1 month after an index episode for acute decompensated heart failure (ADHF).

METHODS AND RESULTS

This is a nested case-control study in the ReIC cohort, cases being consecutive patients readmitted after hospitalization for an episode of ADHF and matched controls selected from those who were not readmitted. We collected clinical data and also patient-reported outcome measures, including dyspnea, Minnesota Living with Heart Failure Questionnaire (MLHFQ), Tilburg Frailty Indicator (TFI) and Hospital Anxiety and Depression Scale scores, as well as symptoms during a transition period of 1 month after discharge. We created a multivariable conditional logistic regression model. Despite cases consulted more than controls, there were no statistically significant differences in changes in treatment during this first month. Patients with chronic decompensated heart failure were 2.25 [1.25, 4.05] more likely to be readmitted than de novo patients. Previous diagnosis of arrhythmia and time since diagnosis ≥ 3 years, worsening in dyspnea, and changes in MLWHF and TFI scores were significant in the final model.

CONCLUSION

We present a model with explanatory variables for readmission in the short term for ADHF. Our study shows that in addition to variables classically related to readmission, there are others related to the presence of residual congestion, quality of life and frailty that are determining factors for readmission for heart failure in the first month after discharge.

Prevalence of transthyretin cardiac amyloidosis in elderly patients diagnosed with heart failure

OBJECTIVE

There is increased interest in studying ATTR-CA, a pathology that primarily affects patients of geriatric age and is frequently underdiagnosed. We aim to establish the prevalence of ATTR-CA in a cohort of patients with a history of HFpEF and to describe its characteristics.

METHODS

We conducted a prospective observational study. Patients ≥75 years, clinical history of HFpEF, atrial dilation ≥34ml/m² and left ventricular wall thickening >13mm, were included. Demographic and analytical parameters were collected, and a comprehensive geriatric assessment was performed, along with a transthoracic echocardiogram and cardiac scintigraphy. Finally, telephone follow-up was carried out at 6 and 12 months.

RESULTS

50 patients were recruited, mean age 86±6 years, 54% women. Age and functional class (I-II vs. III-IV) were factors associated with presenting with ATTR-CA. Patients with positive scintigraphy had a median time to admission of 5.2 months (confidence interval [CI] 95% 0-10.9), while in those with negative scintigraphy, it was 12.2 months (95% CI 11.7-12.8); log-rank: p=0.064. Patients with positive scintigraphy had a median time to the combined endpoint (death and readmission) of 1.9 months (95% CI 0-6.1), and patients with negative scintigraphy of 11.9 months (95% CI 11.7-12); log-rank: p=0.027.

CONCLUSIONS

ATTR-CA appears to be a prevalent etiology in elderly patients within the spectrum of HFpEF. Patients with a diagnosis of ATTR-CA had a shorter time to admission for HF and the combined event of death and admission than patients with a negative result on scintigraphy.

Instrumental activities of daily living trajectories and risk of mild cognitive impairment among Chinese older adults: results of the Chinese longitudinal healthy longevity survey, 2002-2018

Background

The association between the instrumental activities of daily living (IADL) score and the risk of initial cognitive function impairment is inconclusive. We aimed to identify distinctive IADL trajectories and examine their relationship with the onset of mild cognitive impairment (MCI) among Chinese older people.

Methods

The study used six-wave longitudinal data from the Chinese Longitudinal Healthy Longevity Survey conducted between 2002 and 2018. It included a total of 11,044 Chinese people aged 65 years or older. A group-based trajectory model was used to identify distinctive trajectories of the IADL score, and the Cox proportional hazards model was used to explore the hazard ratio of various trajectories at the onset of MCI. Interaction analysis was used to analyze individual modification between the IADL trajectories and the onset of MCI. Finally, we adopted four types of sensitivity analysis to verify the robustness of the results.

Results

During a median follow-up of 16 years, the incidence of MCI was 6.29 cases per 1,000 person-years (95% confidence interval [CI] 5.92-6.68). Three distinct IADL trajectory groups were identified: a low-risk IADL group (41.4%), an IADL group with increasing risk (28.5%), and a high-risk IADL group (30.4%). Using the Cox proportional hazards model after adjusting for covariates, we found that compared with the low risk IADL group, the hazard ratio of the IADL group with increasing risk was 4.49 (95% CI = 3.82-5.28), whereas that of the high-risk IADL group was 2.52 (95% CI 2.08-3.05). Treating the IADL group with increasing risk as the reference, the hazard ratio for the high-risk IADL group was 0.56 (95% CI 0.48-0.66). Interaction analyses showed that age and residence were significant moderators (P for interaction <0.05).

Conclusion

A group-based trajectory model was developed to classify older people into three distinct trajectory groups of the IADL score. The IADL group with increasing risk had a greater risk of MCI than the high-risk IADL group. In the IADL group with increasing risk, city residents of ≥80 years were the most likely to develop MCI.

Evaluation of improvement of functional independence in a multicentre cohort of rehabilitation outpatients with neurological conditions

PURPOSE

The objectives were to examine: (1) the changes in independence in basic activities of daily living (ADL) following an outpatient occupational therapy (OT) intervention in people with neurological conditions; (2) the factors associated with good relative functional gain (RFG) and with good OT efficiency; (3) and the effects on instrumental activities of daily living (IADL) and caregiver assistance.

MATERIALS AND METHODS

A prospective observational study examining changes in a multicentre cohort (three urban hospitals). Ninety-eight adults were assessed on admission and after intervention. Barthel Index was the primary outcome (ADL).

RESULTS

Acquired brain damage (ABI) was the most frequent diagnosis (84.7%). There was an improvement in ADL (p < 0.001); the effect size (r) was large (r = 0.59). RFG was good for 88.8% of participants. A good RFG was significantly associated with ABI, a lower number of hours of caregiver assistance, and a greater intensity of OT. The OT efficiency was good for 43.9% of participants. Factors significantly associated with good efficiency were being young and male patients, and receiving fewer hours of caregiver assistance. Secondary measures were improved: IADL (p < 0.001) and hours of caregiver assistance (p < 0.001).

CONCLUSIONS

This study suggests that the intervention is an effective approach to improve functional independence.Implications for rehabilitationLittle is known about the outcomes of outpatient occupational therapy intervention in neurorehabilitation services for the adult population with neurological diseases.In a multicentre cohort of neurorehabilitation outpatients, the occupational therapy intervention can lead to improvements in the level of independence in basic and instrumental daily activities, as well as reducing the hours of caregiver assistance.A good relative functional gain is associated with acquired brain injury, a lower number of hours of assistance, and a greater intensity of occupational therapy.The factors associated with good efficiency are being younger, male patients, and receiving fewer hours of assistance.

Preventing frailty with the support of a home-monitoring and communication platform among older adults-a study protocol for a randomised-controlled pilot study in Sweden

Background

POSITIVE (i.e. maintaining and imPrOving the intrinSIc capaciTy Involving primary care and caregiVErs) is a new intervention program consisting of home-monitoring equipment and a communication platform to support treatment of frailty symptoms initially in primary care and prevent disability in older adults.

Methods

The primary objectives are to estimate the potential efficacy of the POSITIVE system on improving frailty in at least one point in Fried’s criteria and five points in Frailty Trait Scale. The secondary objectives are to (A) assess the recruitment, retention, drop-out rates, compliance with the intervention and the intervention mechanisms of impact; (B) evaluate the usability and acceptance of the POSITIVE system, and to get estimations on; (C) the potential efficacy of the intervention on improving the participants’ physical performance, cognitive functions, mood, independency level in activities in daily living, the impact on quality of life and number of falls during the follow-up period; (D) the impact on the caregiver quality of life and caregiver burden; and (E) on the consumption of health care resources, participants’ perception of health and level of care received, and healthcare professionals’ workload and satisfaction.

A randomised controlled, assessor-blinded pilot study design recruiting from a primary care centre in Stockholm Region will be conducted. Fifty older adults identified as pre-frail or frail will be randomised into a control or an intervention group. Both groups will receive a medical review, nutritional recommendations and Vivifrail physical exercise program. The intervention group will receive the POSITIVE-system including a tablet, the POSITIVE application and portable measurement devices. The participants receiving the POSITIVE program will be monitored remotely by a primary care nurse during a 6-month follow-up. Data will be collected at baseline, 3 and 6 months into the intervention though the platform, standardised assessments and surveys. A process evaluation as per Medical Research Council guidance will be conducted after the 6-month follow-up period.

Discussion

The implications of the study are to provide estimations on the potential efficacy of the POSITIVE system in improving frailty among older adults and to provide relevant data to inform powered studies of potential efficacy and effectiveness, as well as to inform about the feasibility of the current study design.

Primary and Secondary Caregivers of People with Dementia (PwD): Differential Patterns and Implications for Psychological Support

Very little attention has been paid to identifying the differential characteristics of primary and secondary dementia caregivers. The aims of this study were: to determine whether differences exist between primary and secondary caregivers of people with dementia (PwD) and to explore the profile of primary and secondary caregivers reporting symptoms of anxiety and/or depression. The participants were 146 caregivers of PwD, 73 primary caregivers and 73 secondary caregivers. The results revealed different patterns for each type of caregiver. Primary caregivers showed a more negative profile in terms of poorer self-rated health and higher levels of anxiety and depression: 61.6% of primary and 42.5% of secondary caregivers reported symptoms of anxiety, and 24.7% and 11% reported depression, respectively. The frequency of problem behavior, subjective burden, health, and the comorbidity between anxiety and depression were associated with depression and anxiety among primary caregivers, whereas gender (being a woman), subjective burden, health, and the comorbidity between anxiety and depression were associated among secondary caregivers. These findings may help to guide professionals in targeting psychological support programs and customizing the strategies and skills that need to be provided in accordance with the type of caregiver in question: primary or secondary. The practical implications of the findings are discussed.

Association between physical activity and physical and functional performance in non-institutionalized Mexican older adults: a cohort study

BACKGROUND

Aging is an independent risk factor for deterioration in functional capacity. Some studies have reported that physical activity (PA) improves functional capacity and physical performance among older adults (OA). Thus the objective of the present study was to assess the longitudinal association between PA and functional and physical performance in non-institutionalized OA.

METHODS

A longitudinal analysis using data from the Frailty, Dynapenia and Sarcopenia in Mexican adults (FRADYSMEX, by its Spanish acronym) cohort study was conducted. PA was assessed through the Community Healthy Activities Model Program for Seniors (CHAMPS) instrument. Functionality was measured with the Barthel index and the Lawton and Brody scale, while physical performance was measured with the Short Physical Performance Battery (SPPB). To evaluate the association between the level of PA and physical and functional performance as a continuous variable, a linear regression of mixed effects was performed. To assess PA and dependence in basic activities of the daily life (BADL), instrumental activities of the daily life (IADL), and low physical performance (PP), generalized estimation equation models [to compute odds ratios (OR) and 95% confidence intervals (95%CI)] were computed.

RESULTS

Older people who performed moderate to vigorous-intensity PA had a lower risk of dependence in IADL (OR = 0.17; 95%CI: 0.10, 0.80) and lower risk of low PP (OR = 0.18; 95%CI: 0.11, 0.58) compared to those in lower categories of PA.

CONCLUSIONS

Older adults living in the community who perform PA of moderate to vigorous intensity have a lower risk of dependence in BADL and IADL and have a lower risk of low PP.

How Do Intergenerational Economic Support, Emotional Support and Multimorbidity Affect the Catastrophic Health Expenditures of Middle-Aged and Elderly Families?–Evidence From CHARLS2018

Objectives

The elderly face multiple vulnerabilities such as health, economy and society, and are prone to catastrophic health expenditures. This study aims to analyze the impact of children's intergenerational economic support, emotional support, and illness on the catastrophic health expenditures of middle-aged and elderly families.

Methods

Using China Health and Retirement Longitudinal Study (CHARLS 2018) data to calculate the catastrophic health expenditure of Chinese households as the dependent variable. Taking children's intergenerational economic support, emotional support and multimorbidity as core independent variables, gender, age, marital status, medical insurance and other variables as control variables, and perform logistic regression analysis. According to the heterogeneity analysis of age and gender, the impact of intergenerational economic support, emotional support and multimorbidity on the catastrophic health expenditure of middle-aged and elderly families is explored.

Results

When catastrophic health expenditures occur in middle-aged and elderly families, the children's intergenerational economic support will increase significantly, especially in families with members aged 60–74. Children's emotional support can effectively reduce the risk of catastrophic health expenditures for middle-aged and elderly families. Compared with children's intergenerational economic support and emotional support, the impact of multimorbidity on the catastrophic health expenditures of middle-aged and elderly families is the most significant. Suffering from multimorbidity can increase the risk of catastrophic health expenditures for middle-aged and elderly families, especially families with male members suffering from multiple diseases.

Conclusions

It is recommended that we should do a good job in popularizing the knowledge of chronic diseases to minimize the occurrence of multimorbidity. The government should establish group medical insurance related to chronic disease diagnosis. According to the severity of the disease or the special circumstances of the patient, the level of medical insurance reimbursement is divided in detail, especially for chronic disease clinics and drug reimbursement. Children should be encouraged to strengthen the emotional connection and effective care of the elderly, focusing on the elderly 60–74 years old, in order to reduce their care pressure and maintain the physical and mental health of the elderly.

Evaluation of a patient-centered integrated care program for individuals with frequent hospital readmissions and multimorbidity

Managing patients with multimorbidity and frequent hospital readmissions is a challenge. Integrated care programs that consider their needs and allow for personalized care are necessary for their early identification and management. This work aims to describe these patients' clinical characteristics and evaluate a program designed to reducing readmissions. This prospective study analyzed all patients with ≥ 3 admissions to a medical department in the previous year who were included in the Internal Medicine Department chronic care program at the Lucus Augusti University Hospital (Lugo, Spain) between April 1, 2019 and April 30, 2021. A multidimensional assessment, personalized care plan, and proactive follow-up with a case manager nurse were provided via an advanced hospital system. Clinical and demographic variables and data on healthcare system use were analyzed at 6 and 12 months before and after inclusion. Descriptive and survival analyses were performed. One hundred sixty-one patients were included. Program participants were elderly (mean 81.4 (SD 11) years), had multimorbidity (10.2 (3) chronic diseases) and polypharmacy (10.6 (3.5) drugs), frequently used the healthcare system, and were highly complex. Most were included for heart failure. The program led to significant reductions in admissions and emergency department visits (p = .0001). A total of 44.7% patients died within 1 year. The PROFUND Index showed good predictive ability (p = .013), with high values associated with mortality (RR 1.15, p = .001). Patients with frequent hospital readmissions are highly complex and need special care. A personalized integrated care program reduced admissions and allowed for individualized decision-making.

All-cause mortality and cardiovascular events in a Spanish nonagenarian cohort according to type 2 diabetes mellitus status and established cardiovascular disease

Background

Despite the progressive aging of the population in industrialized countries, few studies have focused on the natural history of cardiovascular disease in the very old, and recommendations on prevention of cardiovascular disease in this population are lacking. We aimed to analyze all-cause mortality and cardiovascular events according to prevalent type 2 diabetes mellitus and established cardiovascular disease in nonagenarians from a Mediterranean population.

Methods

We analyzed the primary health records of all nonagenarians living in the Community of Madrid (N = 59,423) and collected data for 4 groups: Group 1, individuals without T2DM or established CVD (T2DM-, CVD-); Group 2, individuals without T2DM but with established CVD (T2DM-, CVD +); Group 3, individuals with T2DM but without established CVD (T2DM + , CVD-); and Group 4, individuals with both T2DM and established CVD (T2DM + , CVD +), taking into account the influence of sex on the outcomes. Follow-up was 2.5 years. The primary outcomes were cumulative incidence and incidence density rates for all-cause mortality, non-fatal myocardial infarction, non-fatal stroke (the first composite primary outcome [CPO1]), combined with heart failure (CPO2). We evaluated the adjusted effect of each group on all-cause mortality (Cox regression).

Results

Mean age was 93.3 ± 2.8 years (74.2% women). Hypertension, dyslipidemia, heart failure, albuminuria, and estimated glomerular filtration rate < 60 mL/min/1.73 m2 were significantly more prevalent in G4 than in the other groups (all p values < 0.001). We observed significantly higher cumulative incidence rates for all-cause mortality, CPO1, and CPO2 in participants belonging to G4 (all p values ≤ 0.001). People in G2 presented higher rates of all-cause mortality, heart failure, CPO1, and CPO2 than people in G3 (all p values ≤ 0.001). In the fully adjusted model, G4 independently predicted all-cause mortality (HR = 1.48 [95% CI, 1.40 to 1.57] vs reference G1 [p < 0.01]). In addition, significant HRs were recorded for cardiovascular disease alone (G2) and type 2 diabetes mellitus alone (G3) (1.13 and 1.14, respectively; both p values < 0.01).

Conclusions

In Spanish nonagenarians, established cardiovascular disease and type 2 diabetes mellitus conferred a modest risk of all-cause mortality. However, the simultaneous presence of both conditions conferred the highest risk of all-cause mortality.

Information Communication Technology as Instrumental Activities of Daily Living for Aging-in-Place in Chinese Older Adults With and Without Cognitive Impairment: The Validation Study of Advanced Instrumental Activities of Daily Living Scale

Background

The capability in applying information communication technology (ICT) is crucial to the functional independence of older peoples of community living nowadays. The proper assessment of individuals' capability of ICT application is the corner stone for the future development of telemedicine in our aging population.

Methods

With the recruitment of 300 participants of different functional and social background in home-living, hostel-living, and care-and-attention home living; and through assessing the ability of individuals in instrumental activities of daily living and cognitive assessments, this study aimed at capturing the content validity and construct validity of the Advanced Instrumental Activities of Daily Living (AIADL scale). In addition, this study assess the ability of older peoples in applying ICT and how the functional and social background affects their independence in aging-in-place.

Results

The AIADL scale showed good test-retest reliability and good-to-excellent internal consistency. To determine if items of the AIADL scale measure various aspects of community living, exploratory factor analysis revealed a two-factor structure with “home living and management” and “community living”. Validity analysis with the known-groups method showed a high overall accuracy of prediction of individuals' capability of independent living in the community.

Conclusions

The AIADL scale is a valid and reliable instrument to assess the ability of older adults in handling ICT as part of their instrumental activities in daily living. The scale can reflect capability of older peoples in applying ICT. This instrument can serve as a reference in measuring readiness of individuals in receiving telemedicine and their ability of aging-in-place.

Geriatric co-management and interdisciplinary transitional care reduced hospital readmissions in frail older patients in Argentina: results from a randomized controlled trial

BACKGROUND

Hospitalization is a moment of extreme vulnerability for frail older adults. There is scarce evidence on the effectiveness of geriatric co-management or transitional care interventions in Latin America.

AIMS

To assess whether geriatric co-management combined with an interdisciplinary transitional care intervention could reduce 30-day hospital readmission rate compared to usual care in hospitalized frail older patients in a tertiary hospital in Argentina.

METHODS

Single-blinded randomized controlled trial. Usual care treatment arm: all procedures performed during hospitalization were overseen by a senior internal medicine specialist and complied with pre-defined protocols. Patients had access to specialist care if needed, as well as hospital-at-home or home-based primary care services after discharge. Intervention treatment arm: in addition to usual care, a geriatric co-management team performed a comprehensive geriatric assessment during hospitalization, provided tailored recommendations to minimize geriatric syndromes and planned transition of care. A health and social care counselor oversaw continuity of care in patients' homes after discharge.

RESULTS

We included 120 participants in each of the intervention and usual care (control) arms. Thirty-day hospital readmissions were 47.7% lower in the intervention arm (18.3% vs 35.0%; P = 0.040); and emergency room visits within the first 6 months after discharge were 27.8% lower (43.3% vs 60.0%; P = 0.010). There was a non-statistically significant decrease in 6-month mortality in the intervention arm (25.0% vs 35.0%; P = 0.124).

CONCLUSION

Geriatric co-management of frail older patients during hospitalization combined with an interdisciplinary transitional care intervention reduced 30-day hospital readmissions and emergency visits 6 months after discharge.

Substance Use-Related Cognitive Decline in Families with Autosomal Dominant Alzheimer's Disease: A Cohort Study

BACKGROUND

Cigarette smoking is a known risk factor for Alzheimer's disease (AD). However, the association between neurodegeneration and other substances has not been fully determined. It is of vital importance to evaluate this relationship in populations at high risk of dementia. Since substance use possibly modifies the progression rate of cognitive decline, we studied this association in a unique and well-phenotyped cohort from the University of Antioquia: carriers of the PSEN1-E280A genetic variant.

OBJECTIVE

To determine the association between substance use and cognitive decline in carriers of the PSEN1-E280A genetic variant.

METHODS

A retrospective cohort study was conducted with 94 carriers and 69 noncarriers recruited between January 2019 and April 2020. A psychiatrist interviewed the participants using the Consumption of Alcohol, Cigarettes and other Substances questionnaire. The participants were also submitted to cognitive evaluation. The relationship between cognitive decline and substance use was explored through a mixed effects regression model.

RESULTS

There was an association between cigarettes and better performance on tasks related to perceptual organization, verbal fluency, and memory in carriers. Alcohol had a positive or negative effect on memory according to the type of alcoholic beverage. Results on marijuana use were no conclusive. Coffee was associated with progressive improvements in executive function and verbal fluency.

CONCLUSION

Cigarette and alcohol were associated with an improvement of some cognitive assessments, possibly by a survival bias. In addition, coffee was related to improvements in executive function and language; therefore, its short-term neuroprotective potential should be studied.

The Association between Mental Motor Imagery and Real Movement in Stroke

Background: Stroke is the main cause of disability in adults; the most common and long-term sequela is upper-limb hemiparesis. Many studies support the idea that mental motor imagery, which is related to the visualization of movement patterns, activates the same areas of the cortex as if the movement occurred. Objectives: This study aims to examine the capacity to elaborate mental motor images, as well as its relationship to loss of movement in the upper limbs after a stroke. Method: An observational study, in a sample of 39 adults who suffered a stroke, was carried out. The upper limb movement and functionality, cognitive disorders, the ability to visualize mental images, and activities of daily living were examined. Results: The results depicted a statistically significant correlation between the ability to visualize upper limb mental motor images with movement, functionality, and strength. In addition, a correlation between visual–spatial skills and mental visualization of motor ability and upper limb movement was found. Conclusions: These results suggest that the rehabilitation approach focused on the improvement of mental motor imagery could be of interest for the upper limb rehabilitation of movement and functionality.
