Background: Anticholinergic burden (ACB) from medications has been associated with adverse outcomes in older adults. Aim: The aim was to conduct a non-randomized feasibility study of an intervention to reduce the anticholinergic burden in older patients (REGENERATE) to inform a subsequent definitive trial. Methods: The development and evaluation of an ACB reduction intervention was guided by the Medical Research Council framework. Findings from preliminary studies, two systematic reviews, and two qualitative studies informed the design of a mixed-method feasibility study. The study was conducted in one UK primary care site. The clinical pharmacist identified and invited potentially eligible patients, reviewed their medications, and made recommendations to reduce the ACB as needed. Patients completed surveys at baseline and 6 and 12 weeks post-intervention. A purposive sample of patients and healthcare professionals was interviewed. Results: There was a response of 16/20; 14/16 attended the pharmacist-led consultation and completed the baseline questionnaire, and 13/14 completed both follow-up questionnaires. The sustainability of deprescribing was confirmed. The results suggest the potential of the intervention to reduce side effects from medications and improve quality of life (EQ-5D-5L). The interviews showed patients were happy with the study processes and the medication changes and were satisfied with the pharmacist’s consultation. Conclusions: This feasibility study demonstrated that a deprescribing/reducing ACB intervention in older adults is feasible in a primary care setting and may benefit patients. Well-designed RCTs and cost-effectiveness studies should be undertaken to confirm the benefits of ACB deprescribing in primary care settings. Full article

Context: The best treatment for end-stage chronic kidney disease (ESKD) is kidney transplantation (KT). As a result of an aging population, each year more kidney transplants in older adults are performed. Nevertheless, older recipients, characterized by more comorbidities and frailty, raise concerns about the outcomes, potential complications, and the general approach. Aim: The aim of this literature review was to study the outcomes, graft and patient survival, as well as common complications, to establish safety and increase awareness of the potential complications of kidney transplantation in the older population. Methods: PubMed and Google scholar databases were searched. The cut-off age defining an old patient was 60 years. The inclusion criteria were as follows: first kidney transplantation, and studies in English language. The exclusion criteria were as follows: more than one organ transplant, dual transplants, articles published before 2015, meta-analysis, reviews, letter to the editor, case reports, and studies published only as a conference abstract. Comparative and noncomparative studies addressing patient survival, death-censored graft survival, surgical complications, and clinical complications, such as delayed graft function (DGF) and biopsy proven acute rejection (PBAR), were included. Results: After screening the papers, 17 studies met the inclusion criteria and were included for review. Eleven papers compared older recipients with younger recipients and in six papers only older patients were analysed. Two studies used paired deceased donors to eliminate donor bias. The rest of the studies used either deceased donors or both living and deceased donors. The majority of patients were male (61.83%) and received a kidney from a deceased donor (58.08%). Conclusions: Kidney transplantation is safe and can be beneficial for recipients over 60 years of age. Older patients suffered more infectious complications, which were also one of the main reasons for death. Most studies did not show a significant difference in death-censored graft survival compared to the younger population. More research is needed to establish the prevalence of surgical complications, and some clinical complications. Full article

Objective: Imaging biomarkers of bone, muscle, and fat by magnetic resonance imaging (MRI) may depict osteopenia, sarcopenia, and adiposity as the three different conditions of osteosarcopenic adiposity (OSA). Methods: Subjects from a prospective, population-based case–control study underwent a health assessment and 3 Tesla whole-body MRI scan. Imaging biomarkers of bone (bone marrow fat-fraction (BMFF)), skeletal muscle (skeletal muscle FF (SMFF)), and fat (total adipose tissue (TAT)) were determined. Participants were allocated to one phenotype according to the OSA complex. Results: Among 363 participants forming the study cohort, 81 (22.3%, 48.1% males, 62.4 ± 6.9 years) were allocated into the OSA subgroup. Participants with an OSA phenotype were significantly older compared to all remaining subjects and showed the highest grades of SMFF (all p < 0.005). Together with subjects from the osteopenic sarcopenia group, OSA subjects exhibited the highest amounts of BMFF and together with the three other adiposity-containing subgroups also exhibited the highest BMIs. The highest prevalence of an impaired glucose tolerance as well as significantly higher blood pressure, blood dyslipidemia, and hepatic steatosis was found in the OSA subgroup (all p < 0.005). Conclusions: MR biomarkers of bone, skeletal muscle and fat are feasible for body composition phenotyping and may allow for targeted risk stratification in suspected OSA syndrome. Full article

Background/Objectives: A significant proportion of older adults with Alzheimer’s disease or related disorders live in a long-term care facility. This study aimed to determine the time delay between admission and death for older adults with dementia. Methods: A post hoc analysis was conducted using data from a French observational cohort, identifying older adults with dementia who were admitted to nursing homes. This study assessed median survival times after admission to care facilities by using Kaplan–Meier models and evaluated factors potentially associated with the time until death by using Cox models. Results: A total of 201 individuals were included. The median survival time from admission to a nursing home to death was 39 months. Being male, an older age, and having higher cognitive impairment and comorbidities were associated with decreased survival rates. Conclusions: This study provides survival results for institutionalised older adults with dementia in France and provides elements for the definition of future public policies. Full article

Background: The chin-tuck maneuver has been suggested to increase suprahyoid muscle activation, but a method to measure the strength of the chin-tuck maneuver has not been established. We developed a method to measure the strength of the chin-tuck maneuver (chin-tuck strength) and examined the reliability and validity of chin-tuck-strength measurement in community-dwelling older adults. Participants and Methods: The participants were 233 older adults aged ≥65 years without dysphagia or physical disability. Chin-tuck strength was measured twice consecutively using the developed device, and reproducibility was analyzed using intraclass correlation coefficients (ICCs). In addition, maximum tongue pressure, oral diadochokinesis, grip strength, knee extension strength, and the timed up and go test (TUGT) were measured as indices of swallowing-related muscle function and appendicular muscle function. The associations of chin-tuck strength with swallowing-related muscle function and appendicular muscle function were analyzed statistically. Results: The ICCs for chin-tuck strength were 0.82 (95% confidence interval [CI]: 0.73–0.88) in males and 0.87 (95% CI: 0.70–0.93) in females. Chin-tuck strength was significantly associated with maximum tongue pressure, grip strength, knee extension strength, and TUGT. Conclusions: This study suggests that chin-tuck strength is a reliable and valid assessment of swallowing-related muscle strength. Full article

Negative self-perceptions of aging have been linked to poorer health and quality of life and predict significantly depressive symptomatology. The support provided by the partner may have an impact on the effects of self-perceptions of aging on depressive symptoms; a close relationship can go along with additional stress or resources and benefits. The present study analyzes the relationship between negative self-stereotypes and depressive symptomatology, considering positive and negative dyadic coping (DC) as moderator variables in this association. Method: Participants were 365 individuals (convenience sample) 40 years or older (M = 60.86) involved in a partner relationship. Participants completed a questionnaire that included the following variables: negative self-perceptions of aging, positive DC (e.g., “My partner shows empathy and understanding to me”), negative DC (e.g., “When I am stressed, my partner tends to withdraw”), and depressive symptomatology. Two moderation models were tested by linear regression. Results: The effect of negative self-perceptions of aging on depressive symptoms was moderated by positive and negative DC only in women. The effect of negative self-perceptions of aging appears to be smaller among those women with higher levels of positive DC and lower levels of negative DC. Conclusions: Positive DC might buffer the association between negative self-perceptions of aging and depressive symptoms. Negative DC might amplify this association, as it is associated with lower well-being among women who express negative self-perceptions of aging. Implications: Training couples in strategies for providing supportive dyadic coping may be a resource to buffer the negative effect of negative self-perceptions of aging on well-being. Full article

Background: Older people are more likely to have poor nutrition and low muscle mass, which leads to poor physical performance and anemia, resulting in a poor quality of life and risks to mobility and mortality. Furthermore, malnutrition may, in part, raise the level of inflammatory biomarkers as well as muscle catabolism. Moreover, a range of indices related to systemic inflammation, obtained from routine complete blood count (CBC) tests, have been applied to inflammation markers. However, these biomarkers remain insufficiently addressed in the evidence supporting the presence of sarcopenia and malnutrition. This study aimed to explore sarcopenia in terms of malnutrition, anemia, and inflammation among Thai community-dwelling older people. Methods: This study enrolled community-dwelling older people aged 60 years and above. All participants were requested to complete a questionnaire assessing for sarcopenia (SARC-F) and nutritional status using the mini nutritional assessment (MNA). In addition, blood samples were obtained for the CBC test. Logistic regression analysis explored the risk of sarcopenia, CBC, and malnutrition status. Results: Of 126 older people (aged 62–88 years) enrolled, 12 individuals (9.52%) had sarcopenia. Furthermore, 34.9% and 5.56% of the participants were demonstrated to have anemia and malnutrition, respectively. Nutrition status was positively associated with hemoglobin levels (r = 0.241, p = 0.007) and negatively related to SARC-F scores (r = −0.190, p = 0.034). Older people with anemia show an increased risk of malnutrition at an odds ratio (OR) of 3.375. Moreover, individuals with anemia were at a higher risk of developing sarcopenia (OR 4.982) than those with no anemia. However, individuals with a high level of inflammatory markers, e.g., a high systemic inflammatory response index (SIRI) and monocyte-to-lymphocyte ratio (MLR), had a higher risk of sarcopenia than those with low SIRI and MLR values. The systemic immune–inflammation index (SII) and platelet-to-lymphocyte ratio (PLR) were also positively associated with SARC-F scores. Conclusions: The association between sarcopenia, malnutrition status, and anemia might overlap in clinical manifestation. In addition, future research directions regarding the utility of routine CBC testing should focus on sarcopenia and malnutrition status. Full article

Background/Objectives: Respiratory illnesses frequently lead to hospitalization in adults aged 60 and older, especially due to respiratory viral infectious (RVI). This study investigates hospitalization patterns and characteristics of RVI at HM Hospitals from October 2023 to March 2024; Methods: We retrospectively explored hospitalizations of patients aged 60 years and older with RVIs, gathering data on demographics, clinical profiles, comorbidities, and treatments. Outcomes included hospitalization, ICU admissions, and mortality, and independent factors associated with outcomes were identified using a multi-state model; Results: From October 2023 to March 2024, from a total of 3258 hospitalizations, 1933 (59.3%) were identified as positive for RVIs. Overall, SARS-CoV-2 was the most prevalent (52.6%), followed by influenza (32.7%), and RSV (11.8%). Most RVI involved single infections (88.2%). Hospitalization rates increased with age for SARS-CoV-2 (333.4 [95% CI: 295.0–375.2] to 651.6 [95% CI: 532.1–788.4]), influenza (169.8 [95% CI: 142.6–200.7] to 518.6 [95% CI: 412.1–643.1]), and RSV (69.2 [95% CI: 52.2–90.0] to 246.0 [95% CI: 173.8–337.5]), with SARS-CoV-2 showing the highest rate, followed by influenza and RSV. In the multi-state model, RSV infection significantly increased ICU admission risk (HR: 2.1, 95%, p = 0.037). Age on admission (HR: 1.1, 95%, p < 0.001) and Charlson score (HR: 1.4, 95%, p = 0.001) were associated with transitioning from admission to death. ICU to death risks included age at admission (HR: 1.7, 95%, p < 0.001); Conclusions: RVI in adults 60 years and older are associated with high hospitalization and mortality rates, primarily driven by influenza and SARS-CoV-2, followed by RSV. Age and comorbidities significantly impact disease severity, emphasizing the need for targeted prevention and management strategies for RSV in this vulnerable population. Full article

Background: Elderly drivers often face safety challenges due to age-related declines in cognitive, sensory, and motor functions. Advanced Driver Assistance Systems (ADAS) offer a potential solution by enhancing safety and mobility. Objectives and method: This systematic review investigates the factors influencing the perception and usage of ADAS among elderly drivers, focusing on perceived safety, usefulness, trust, and ease of use. Results: Older adults show a preference for Level 1 ADAS, which they perceive as safer. Although they acknowledge the usefulness of ADAS in supporting their autonomy, skepticism remains regarding higher-level systems, primarily due to concerns about reliability and invasiveness. Trust and ease of use are essential factors influencing their acceptance. The review identifies common themes and barriers to the adoption of these technologies and emphasizes the need for senior-friendly interfaces and targeted training. The findings indicate that addressing these issues can significantly improve the safety and mobility of elderly drivers. The successful adoption of ADAS among older adults depends on balancing safety, control, and ease of use, with gradual and supportive integration fostering greater acceptance and trust. Conclusions: This study outlines practical implications for stakeholders, emphasizing the need for user-friendly ADAS design, public awareness campaigns, government incentives, insurance discounts, and community training to enhance adoption among older drivers.

Background/Objectives: As people age, their environment plays a critical role in shaping their health. With Thailand’s rapidly aging population, it is crucial to understand how different living environments affect the well-being of older adults. This study examines differences in biopsychosocial health indicators between older adults living in village communities and private housing estates in Chiang Mai, Thailand. Methods: A cross-sectional study was conducted using baseline data from the Community-Integrated Intermediary Care (CIIC) Service Model, a Cluster Randomized Controlled Trial in Thailand (TCTR20190412004). The study included 2788 older adults (aged 60+). Of these, 89.49% resided in village communities, and 10.51% in private housing estates. Validated instruments were used to assess health indicators. Descriptive statistics, multivariate analysis of variance, and multiple logistic regression analyses were performed. Results: Older adults in private housing estates had significantly lower odds of experiencing pain or discomfort (Adj OR: 0.64, 95% CI: 0.49–0.84) and were 1.36 times more likely to report positive perceived health. However, they had lower odds of perceiving themselves as physically and socially active (Adj OR: 0.74, 95% CI: 0.57–0.97) and were 0.30 times less likely to rate their quality of life higher (Adj OR: 0.30, 95% CI: 0.22–0.40) compared to their village community counterparts. Conclusions: The residential environment significantly influences older adults’ health and well-being. Tailored health promotion interventions should leverage the unique strengths of both village communities and private housing estates to enhance social connections, physical activity, and quality of life, promoting healthy, active aging across diverse settings.

Background/Objectives: Divergent thinking (DT), the ability to generate alternative responses to open-ended problems, has become an increasingly relevant topic in aging research due to its inverse relationship with cognitive decline. Methods: In this narrative review, we explore the latest evidence supporting DT training as a potential strategy for dementia prevention. Results: We identify two pathways through which DT may protect against cognitive decline: (1) by fostering creative cognition and (2) by stimulating DT-related domains. Our findings suggest that verbal DT remains relatively well preserved in older adults, although there is limited empirical evidence to support the idea that DT training enhances creative cognition or DT-related domains in this population. Conclusions: Therefore, while tools designed to enhance DT in older individuals seem promising, it is crucial to rigorously test their effects on the target population to maximize their impact on both the cognitive and psychological domains.

Background: During the time-course of cognitive decline, Behavioral and Psychological Symptoms of Dementia (BPSD) may arise, negatively impacting the outcomes. Methods: The aim of this single center, longitudinal study was to evaluate the correlation between frailty and BPSD in a population of older patients with dementia. BPSD were classified into three clusters: “mood/apathy” (depression, apathy, sleep disturbances, appetite disturbances), “psychosis” (delusions, hallucinations, and anxiety), and “hyperactivity” (agitation, elation, motor aberrant behavior, irritability, disinhibition). Using the Clinical Frailty Scale (CFS), patients were categorized as “severely frail”, “mild/moderately frail” and “robust” (CFS ≥ 7, 4–6, and ≤ 3, respectively). Results: In total, 209 patients (mean age 83.24 ± 4.98 years) with a clinical diagnosis of dementia were enrolled. BPSD were prevalent among the severely frail patients. A positive correlation at regression analysis was found between frailty and “hyperactivity” cluster at baseline and follow-up visits (p < 0.001, p = 0.022, p = 0.028, respectively), and was confirmed at the network analysis. Loss of independence in IADL was correlated to hyperactivity and psychosis symptoms (p < 0.001 and p = 0.013, respectively). Conclusions: Scarce literature is available regarding the correlation between frailty and BPSD, which in our study is significant, especially for symptoms in the hyperactivity cluster. Frailty assessment may help identify patients at the highest risk for developing BPDS who might benefit from targeted intervention in the earliest phases of the disease. Full article

(1) Background: Older adults with chronic stroke may experience compromised upper airway functions due to stroke-related changes and aging. This study aimed to evaluate the functional capacity of the upper airway in older adults with chronic stroke. (2) Methods: A total of 44 patients (22 in each group) were included in the study. The respiratory assessment involved measuring forced vital capacity, forced expiratory volume in one second, maximum voluntary ventilation, and peak cough flow. The voice assessment recorded intensity, frequency, shimmer, and the harmonics-to-noise ratio during a monologue task. Additionally, the maximum phonation time of /a/ and /s/ was recorded. The swallowing assessment included the Eating Assessment Tool—10 and the Swallowing Quality of Life questionnaire. (3) Results: Significant differences were found in the experimental group compared to the control group in maximum voluntary ventilation (44.59 ± 15.61 vs. 58.50 ± 28.08, p = 0.049) and peak cough flow (173.64 ± 101.09 vs. 291.59 ± 176.58, p = 0.009). Additionally, the experimental group showed poorer results than the control group in monologue intensity (66.60 ± 3.72 vs. 114.72 ± 63.09, p = 0.001), the harmonics-to-noise ratio (9.08 ± 2.06 vs. 10.26 ± 1.59, p = 0.042), and the maximum phonation time of /s/ (4.36 ± 1.67 vs. 8.09 ± 4.07, p < 0.001). Patients with stroke also had significantly lower values for swallowing efficiency and safety compared to the control group (7.05 ± 8.44 vs. 2.23 ± 4.14, p = 0.021) and reported poorer quality of life related to swallowing difficulties (185.50 ± 23.66 vs. 200.32 ± 19.60, p = 0.029). (4) Conclusions: Older adults with chronic stroke exhibited significantly reduced cough strength, voice intensity, maximum phonation time, and swallowing function compared to controls. Full article

Well-being and social interaction are among the primary goals to be achieved for the elderly. Intergenerational physical activity (PA) has gained increasing attention due to its potential to encourage PA and social interaction, providing both social and physical benefits to both younger and older individuals. This review aimed to gain a deeper understanding of the potential roles of PA in facilitating intergenerational interactions and provide practical insights. Methods: Following PRISMA guidelines, the systematic review identified specific keywords to search for articles that met the chosen inclusion and exclusion criteria (n. 5 RCT articles, selected between 2009 and 2024), conducted by three independent reviewers. Scopus, PubMed, EBSCOhost, and Web of Science were consulted to identify relevant articles. Risk of bias was assessed using Cochrane RoB 2. For the narrative dissertation, articles were identified across three key areas of focus: types of PA, age groups, and intended goals. Results: Few studies have specifically implemented PA protocols in intergenerational relationships, and most have planned remote activities without monitoring outcomes. The main advantages of intergenerational PA are oriented towards the social and relational sphere rather than simple PA involvement. Conclusions: For the elderly, these programs may help mitigate age-related deficits, while children and adolescents, when adapting to their older counterparts, experience greater effectiveness when provided with clear guidance during shared activities. Considering the characteristics and needs of individuals of different ages, different activities must be proposed to obtain different results. The organization of workshops and preparatory sessions will help in facilitating relationships and interactions among participants. Full article

Background/Objectives: Age-related dysphagia involves sarcopenia and nervous system changes affecting ingestion. The ACT-ING program, a novel task-based occupational therapy intervention, has been developed to improve strength, endurance, and ingestive skills using real-world eating and drinking tasks for older adults with age-related dysphagia. This narrative review evaluates the outcomes and neuromuscular adaptations of task-based eating and drinking interventions in aging animal models to inform potential refinements of the ACT-ING program and interpret results from an ongoing proof-of-concept study. Methods: Publications were obtained from PubMed, SCOPUS, CINAHL, and EMBASE, and selected following the PRISMA guideline. Thirteen randomized trials investigated a task-based fluid-licking intervention in rats, combining strength, endurance, and skill training. Results: Results suggested benefits in improving muscle strength, endurance, and swallowing skills in terms of quantity and speed. Although neuromuscular adaptations were less conclusive, the intervention appeared to induce cortical plasticity and increase fatigue-resistant muscle fibers in the involved muscles. Conclusions: While these findings are promising, methodological concerns and potential biases were identified. Therefore, further research is necessary to refine the ACT-ING program, including both clinical studies in humans and preclinical studies in aging animal models that clearly define interventions targeting all aspects of ingestion-related skills within a motor learning and strength training framework.
