Multifaceted Interventions Inclusive of Medication Optimization for Frailty in Aged Care: A Systematic Review.

OBJECTIVES: Implementation of best practice frailty guidelines in residential aged care is currently unclear, and there is a particular scarcity of evidence regarding multifaceted frailty treatments inclusive of medication optimization in these settings, despite the bidirectional relationship between polypharmacy and frailty. This review aimed to retrieve all relevant literature and evaluate the effect of medication optimization delivered in conjunction with exercise and/or nutritional interventions in the best-practice management of frailty in residential aged care. DESIGN: Systematic review with a qualitative synthesis. SETTINGS AND PARTICIPANTS: Older adults residing within residential aged care (otherwise referred to as nursing homes or long-term care). METHODS: The protocol was prospectively registered on PROSPERO (Reg. No.: CRD42022372036) using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Five electronic databases were searched from inception to November 23, 2023, with alerts monitored until March 28, 2024. Quality of studies was assessed using the ROB 2 and ROBIN-1 tools. RESULTS: A total of 10,955 articles were retrieved; 62 full articles were reviewed, with 3 studies included (2 randomized controlled trials and 1 nonrandomized controlled trial) involving 1030 participants. Included studies did not use specific frailty scores but reported individual components of frailty such as weight loss or number of medications prescribed. No trial combining medication review, exercise, and nutrition was identified. Medication review reduced the number of medications prescribed, whereas the use of nutritional support reduced gastrointestinal medication and maintained weight. CONCLUSION AND IMPLICATIONS: There is no published research investigating best-practice guidelines for medication optimization used in combination with both exercise and nutrition in aged care to address frailty. This review confirms the need for studies implementing Consensus Guidelines for frailty treatment in this vulnerable cohort.

A Deep Learning-Based Rotten Food Recognition App for Older Adults: Development and Usability Study.

BACKGROUND: Older adults are at greater risk of eating rotten fruits and of getting food poisoning because cognitive function declines as they age, making it difficult to distinguish rotten fruits. To address this problem, researchers have developed and evaluated various tools to detect rotten food items in various ways. Nevertheless, little is known about how to create an app to detect rotten food items to support older adults at a risk of health problems from eating rotten food items. OBJECTIVE: This study aimed to (1) create a smartphone app that enables older adults to take a picture of food items with a camera and classifies the fruit as rotten or not rotten for older adults and (2) evaluate the usability of the app and the perceptions of older adults about the app. METHODS: We developed a smartphone app that supports older adults in determining whether the 3 fruits selected for this study (apple, banana, and orange) were fresh enough to eat. We used several residual deep networks to check whether the fruit photos collected were of fresh fruit. We recruited healthy older adults aged over 65 years (n=15, 57.7%, males and n=11, 42.3%, females) as participants. We evaluated the usability of the app and the participants' perceptions about the app through surveys and interviews. We analyzed the survey responses, including an after-scenario questionnaire, as evaluation indicators of the usability of the app and collected qualitative data from the interviewees for in-depth analysis of the survey responses. RESULTS: The participants were satisfied with using an app to determine whether a fruit is fresh by taking a picture of the fruit but are reluctant to use the paid version of the app. The survey results revealed that the participants tended to use the app efficiently to take pictures of fruits and determine their freshness. The qualitative data analysis on app usability and participants' perceptions about the app revealed that they found the app simple and easy to use, they had no difficulty taking pictures, and they found the app interface visually satisfactory. CONCLUSIONS: This study suggests the possibility of developing an app that supports older adults in identifying rotten food items effectively and efficiently. Future work to make the app distinguish the freshness of various food items other than the 3 fruits selected still remains.

Frailty and biological age. Which best describes our aging and longevity?

Frailty and Biological Age are two closely related concepts; however, frailty is a multisystem geriatric syndrome that applies to elderly subjects, whereas biological age is a gerontologic way to describe the rate of aging of each individual, which can be used from the beginning of the aging process, in adulthood. If frailty reaches less consensus on the definition, it is a term much more widely used than this of biological age, which shows a clearer definition but is scarcely employed in social and medical fields. In this review, we suggest that this Biological Age is the best to describe how we are aging and determine our longevity, and several examples support our proposal.

Hospital Staff Perspectives on the Drivers and Challenges in Implementing a Virtual Rehabilitation Ward: Qualitative Study.

Background: Over the past decade, the adoption of virtual wards has surged. Virtual wards aim to prevent unnecessary hospital admissions, expedite home discharge, and enhance patient satisfaction, which are particularly beneficial for the older adult population who faces risks associated with hospitalization. Consequently, substantial investments are being made in virtual rehabilitation wards (VRWs), despite evidence of varying levels of success in their implementation. However, the facilitators and barriers experienced by virtual ward staff for the rapid implementation of these innovative care models remain poorly understood. Objective: This paper presents insights from hospital staff working on an Australian VRW in response to the growing demand for programs aimed at preventing hospital admissions. We explore staff's perspectives on the facilitators and barriers of the VRW, shedding light on service setup and delivery. Methods: Qualitative interviews were conducted with 21 VRW staff using the Nonadoption, Abandonment, Scale-up, Spread, and Sustainability (NASSS) framework. The analysis of data was performed using framework analysis and the 7 domains of the NASSS framework. Results: The results were mapped onto the 7 domains of the NASSS framework. (1) Condition: Managing certain conditions, especially those involving comorbidities and sociocultural factors, can be challenging. (2) Technology: The VRW demonstrated suitability for technologically engaged patients without cognitive impairment, offering advantages in clinical decision-making through remote monitoring and video calls. However, interoperability issues and equipment malfunctions caused staff frustration, highlighting the importance of promptly addressing technical challenges. (3) Value proposition: The VRW empowered patients to choose their care location, extending access to care for rural communities and enabling home-based treatment for older adults. (4) Adopters and (5) organizations: Despite these benefits, the cultural shift from in-person to remote treatment introduced uncertainties in workflows, professional responsibilities, resource allocation, and intake processes. (6) Wider system and (7) embedding: As the service continues to develop to address gaps in hospital capacity, it is imperative to prioritize ongoing adaptation. This includes refining the process of smoothly transferring patients back to the hospital, addressing technical aspects, ensuring seamless continuity of care, and thoughtfully considering how the burden of care may shift to patients and their families. Conclusions: In this qualitative study exploring health care staff's experience of an innovative VRW, we identified several drivers and challenges to implementation and acceptability. The findings have implications for future services considering implementing VRWs for older adults in terms of service setup and delivery. Future work will focus on assessing patient and carer experiences of the VRW.

Medication administration in aged care facilities: A mixed-methods systematic review.

AIM(S): To synthesize aged care provider, resident and residents' family members' perspectives and experiences of medication administration in aged care facilities; to determine the incidence of medication administration errors, and the impact of medication administration on quality of care and resident-centredness in aged care facilities. DESIGN: A mixed-methods systematic review. PROSPERO ID: CRD42023426990. DATA SOURCES: The AMED, CINAHL, MEDLINE, EMBASE, EMCARE, PsycINFO, Scopus and Web of Science core collection databases were searched in June 2023. REVIEW METHODS: Included studies were independently screened, selected and appraised by two researchers. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist was followed, with the Mixed Methods Appraisal Tool was used for critical appraisal. Convergent synthesis of data, thematic synthesis and meta-analysis were performed. RESULTS: One hundred and twenty-eight studies were included (33 qualitative, 85 quantitative and 10 mixed-methods). Five themes were formulated, including 1) Staffing concerns, 2) The uncertain role of residents, 3) Medication-related decision-making, 4) Use of electronic medication administration records and 5) Medication administration errors. Educational interventions for aged care workers significantly reduced medication administration errors, examined across five studies (OR = 0.37, 95%CI 0.28-0.50, p < .001). CONCLUSIONS: Medication administration in aged care facilities is challenging and complex on clinical and interpersonal levels. Clinical processes, medication errors and safety remain focal points for practice. However, more active consideration of residents' autonomy and input by aged care workers and providers is needed to address medication administration's interpersonal and psychosocial aspects. New directions for future research should examine the decision-making behind dose form modification, aged care workers' definitions of medication omission and practical methods to support residents' and their family members' engagement during medication administration. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: It is important that medication administration in aged care facilities be more clearly acknowledged as both a clinical and interpersonal task. More attention is warranted regarding aged care workers clinical decision-making, particularly concerning dose form modification, covert administration and medication omissions. Resident-centred care approaches that support resident and family engagement around medication administration may improve adherence, satisfaction and quality of care. IMPACT: What Problem Did the Study Address? Medication administration in aged care facilities is a complex clinical and interpersonal activity. Still, to date, no attempts have been made to synthesize qualitative and quantitative evidence around this practice. There is a need to establish what evidence exists around the perspectives and experiences of aged care workers, residents and resident's family members to understand the challenges, interpersonal opportunities and risks during medication administration. What Were the Main Findings? There is a lack of empirical evidence around resident-centred care approaches to medication administration, and how residents and their families could be enabled to have more input. Dose form modification occurred overtly and covertly as part of medication administration, not just as a method for older adults with swallowing difficulties, but to enforce adherence with prescribed medications. Medication administration errors typically included medication omission as a category of error, despite some omissions stemming from a clear rationale for medication omission and resident input. WHERE AND ON WHOM WILL THE RESEARCH HAVE AN IMPACT?: The findings of this systematic review contribute to aged care policy and practice regarding medication administration and engagement with older adults. This review presents findings that provide a starting point for aged care workers in regards to professional development and reflection on practice, particularly around clinical decision-making on dose form modification, medication administration errors and the tension on enabling resident input into medication administration. For researchers, this review highlights the need to develop resident-centred care approaches and interventions, and to assess whether these can positively impact medication administration, resident engagement, adherence with prescribed medications and quality of care. REPORTING METHOD: This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (Page et al., 2021). PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution to this systematic review.

Higher Education Institutions as Strategic Centers for Promoting Social Innovation in Gerontology: Insights from the Senior Innovation Lab Training Initiative.

BACKGROUND: Social innovation and gerontology develop a wide range of actions aimed at supporting and improving the needs of long-lived populations. Higher education institutions (HEIs) are drivers of change, and their potential to develop solutions through teaching students' social innovation skills should be considered in the field of longevity. This article reports the results obtained by the Senior Innovation Lab (SIL) training initiative. METHODS: Challenge-based learning, design thinking, and lean startup approaches were implemented in training 26 participants with the final aim of developing innovative solutions to previously identified long-lived population needs. RESULTS: Final products were innovative ideas developed through collaboration between students, academic staff, and business employees, indicating the importance of adopting entrepreneurial approaches in academic teaching. The participants identified motivation and perseverance as the most relevant entrepreneurial skills and most of them also perceived that they possessed it. The participants also considered spotting opportunities (chance to add value) as the most desired skill throughout the whole experience. CONCLUSIONS: SIL's assessment showed that social innovation methodologies contributed to the development of learning strategies, enabling potential solutions for the ageing challenges.

Health professionals' perceptions of prehabilitation before haematopoietic cell transplantation to optimise candidacy in older adults.

PURPOSE: Haematologic malignancies for the most part are diseases of the elderly. Haematopoietic stem cell transplantation (HSCT) remains the only potentially curative strategy for many patients but carries substantial morbidity and mortality risks, particularly in frail or co-morbid patients. Pre-transplant optimisation of key targets through prehabilitation may have significant clinical impact. METHODS: We utilised qualitative methodology (semi-structured interviews) to gain insights and understanding of the perceptions of medical, nursing and allied health professionals towards prehabilitation before haematopoietic cell transplantation to optimise candidacy in older adults. Thematic analysis was performed using a qualitative descriptive approach completed in duplicate by two researchers. RESULTS: Between August and October 2023, eleven health professionals participated from four large cancer centres across the island of Ireland (n = 3 consultant haematologists, n = 7 specialist haematology nurses and n = 1 senior haematology physiotherapist). Four major themes were identified. The themes comprehensive biopsychosocial care and increasing demand for transplant in older patients highlight the unique challenges impacting older adults who receive HSCT. The multimodality pathways of care theme highlights the heterogeneity of treatment pathways across different clinical sites and disease types. This has implications for the prehabilitation: logistics and benefits theme, which indicated strong support for prehabilitation but emphasised that implementation must consider national reach and context. CONCLUSIONS: There is broad national multidisciplinary interest in the development of prehabilitation programmes for patients being considered for transplant. Our results will inform the development of services in this area in consideration of national reach, malignancy-specific pathways and the unique factors associated with older age.

Student experiences with an interprofessional hope-based healthy aging research project.

Interprofessional education (IPE) and research enhances learning, team-based communication, and cross-disciplinary collaborations, which can result in higher quality care for older adults. Despite the importance of IPE, it remains underutilized in higher education, demonstrating the need for extracurricular IPE opportunities. This study describes an interprofessional research project that brought together faculty, undergraduate, and graduate students from several health and social science disciplines to design and deliver a 15-week healthy aging program for older adults living in the urban Circumpolar North. Five faculty and one graduate research assistant led the project while eight students team-taught weekly, 1-hour sessions in the community focusing on healthy lifestyles within a framework of Persuasive Hope Theory. This paper describes the project, the student training procedures, and reports the results of the student satisfaction survey regarding their involvement with the research. Using a student self-assessment survey, students report gains in thinking like a scientist, increased confidence conducting research tasks, benefits from teamwork, and greater consideration of the needs of older adults in their field of study. Despite a small sample size, this study also suggests that students may be more likely to consider a career working with older adults if given hands-on experiences.

Mammal Aging as a Programmed Life Cycle Function - Resolving the Cause and Effect Conundrum.

Because aging and internally determined lifespan vary greatly between similar species it is now widely accepted that aging is an evolved trait, resulting in two classes of evolutionary aging theories: aging is programmed by complex biological mechanisms, and aging is not programmed. As recently as 2002 programmed aging is thought to be theoretically impossible. However, genetics discoveries, results of selective breeding, and other direct evidence strongly support the idea that aging creates an evolutionary advantage and that therefore complex biological mechanisms evolved that control aging in mammals and other multiparous organisms. Like life-cycle programs that control reproduction, growth, and menopause the aging program can adjust the aging trait during an individual's life to compensate for temporary or local changes in external conditions that alter the optimum lifespan for a particular species population. Genetics discoveries also strongly support the evolvability concept to the effect that sexually reproducing species can evolve design features that increase their ability to evolve, and that aging is one such feature. Genetics discoveries also prove that biological inheritance involves transmission of organism design information in digital form between parent and descendant of any organism. This has major implications for the evolution process.

Perspectives of Family Caregivers on Healthcare Provided to Older Adults With Hypertension and/or Diabetes Mellitus in Ghana.

This study explored the perspectives of family caregivers of older adults with hypertension and/or diabetes mellitus on the care provided to their kin when they visit the hospital. A qualitative research approach was used to conduct the study using family members providing informal care for older adults with hypertension and/or diabetes mellitus at a teaching hospital in Ghana. A total of 20 participants were purposively sampled, interviewed, and data was analyzed using reflexive thematic analysis. Family caregivers mainly had perceptions that their older adult kin had poor interactions with the healthcare system because of some healthcare workers' negative attitudes, inadequate facilities at the clinics, and lack of geriatric care services at the facility. This notwithstanding, family caregivers also derived some benefits from accompanying their kin to the hospital. Practice and education in gerontological nursing must be employed to pragmatically meet the unique healthcare needs of older adults in Ghana with a focus on geriatrics units and standalone programs of study to prepare specialized healthcare professionals to provide comprehensive services to older adults. For a thorough understanding of issues of older adult care in the country, their perspectives on this subject should also be explored in future studies.

"I just can't go back": Challenging Places for Older Americans since the COVID-19 Pandemic Onset.

During the pandemic, many older adults felt 'out of place' in their home, work, and community spaces with potentially long-term consequences for health and wellbeing. Using national data from the COVID-19 Coping Study, thematic analysis of online long-answer responses (n = 1171; mean age 68 years; 71% female; 93% non-Hispanic White; 86% with at least a 4-year college degree; data collected April-June 2022) identified four themes regarding why particular places are challenging since the pandemic onset: (1) viral exposure fears, (2) frustrating regulations, (3) uncomfortable and hostile social dynamics, and (4) 'out of place' negative emotions. Participants also shared how they continuously address or adapt to place-based challenges through lifestyle adjustments and coping strategies. Novel findings may inform multi-scalar policymaking and interventions to support wellbeing in later life in times of stress and instability.

Lost in Transition: Community-Dwelling Partners' Stories of Losing a Spouse to Cognitive Decline and Long-Term Care Facilities.

This qualitative narrative study presents three stories told by older community-dwelling partners to spouses moving into long-term care facilities because of cognitive decline. Applying Alvesson and Kärreman's mystery method to these stories reveals that when spouses' caring needs increase, care partners must take on increasing loads of practical work and responsibilities. These partners become lost in the transitions between care work, extended family, and attending to their couplehood. When their spouses move into long-term care, living apart presents new challenges of care and couplehood, each day presenting new and unforeseen tasks to manage. Our findings suggest that if couplehood is to be maintained, well-established habits and work division between the spousal partners are both drivers and barriers. It necessitates agency, creativity from the community-dwelling partner, as well as a supportive extended family and sufficient economic resources. More knowledge is required regarding the interdependent expectations between the next-of-kin, long-term care residents, and caregiving staff members.

Carving and making space through dance - Older people using dance to experience their ageing body and challenge ageist discourse.

Drawing on qualitative data from a study of older adults' participation in a contemporary dance group, this paper asks what can be gained from new materialist concepts of the older body, and how they can expand cultural gerontological thinking about embodiment. This paper examines the connections between the older body, movement, thoughts, words and spaces, arguing that dance demonstrates that there is a spatial dimension to embodiment. In drawing from models of materiality emerging in gerontology, this paper provides insights about the experience of age, questioning fundamental categorizations promoted in Western culture, and re-thinks agency in relation to the body and space. Emphasising the importance of the material world in the production of the social has important implications in terms of understanding the experience of ageing within an ageist society.

Computational analysis of value learning and value-driven detection of neutral faces by young and older adults.

The rapid detection of neutral faces with emotional value plays an important role in social relationships for both young and older adults. Recent psychological studies have indicated that young adults show efficient value learning for neutral faces and the detection of "value-associated faces," while older adults show slightly different patterns of value learning and value-based detection of neutral faces. However, the mechanisms underlying these processes remain unknown. To investigate this, we applied hierarchical reinforcement learning and diffusion models to a value learning task and value-driven detection task that involved neutral faces; the tasks were completed by young and older adults. The results for the learning task suggested that the sensitivity of learning feedback might decrease with age. In the detection task, the younger adults accumulated information more efficiently than the older adults, and the perceptual time leading to motion onset was shorter in the younger adults. In younger adults only, the reward sensitivity during associative learning might enhance the accumulation of information during a visual search for neutral faces in a rewarded task. These results provide insight into the processing linked to efficient detection of faces associated with emotional values, and the age-related changes therein.

A Personalized and Interactive Web-Based Advance Care Planning Intervention for Older Adults (Koda Health): Pilot Feasibility Study.

Background: Advance care planning (ACP) is a process that involves patients expressing their personal goals, values, and future medical care preferences. Digital applications may help facilitate this process, though their use in older adults has not been adequately studied. Objective: This pilot study aimed to evaluate the reach, adoption, and usability of Koda Health, a web-based patient-facing ACP platform, among older adults. Methods: Older adults (aged 50 years and older) who had an active Epic MyChart account at an academic health care system in North Carolina were recruited to participate. A total of 2850 electronic invitations were sent through MyChart accounts with an embedded hyperlink to the Koda platform. Participants who agreed to participate were asked to complete pre- and posttest surveys before and after navigating through the Koda Health platform. Primary outcomes were reach, adoption, and System Usability Scale (SUS) scores. Exploratory outcomes included ACP knowledge and readiness. Results: A total of 161 participants enrolled in the study and created an account on the platform (age: mean 63, SD 9.3 years), with 80% (129/161) of these participants going on to complete all steps of the intervention, thereby generating an advance directive. Participants reported minimal difficulty in using the Koda platform, with an overall SUS score of 76.2. Additionally, knowledge of ACP (eg, mean increase from 3.2 to 4.2 on 5-point scale; P<.001) and readiness (eg, mean increase from 2.6 to 3.2 on readiness to discuss ACP with health care provider; P<.001) significantly increased from before to after the intervention. Conclusions: This study demonstrated that the Koda Health platform is feasible, had above-average usability, and improved ACP documentation of preferences in older adults. Our findings indicate that web-based health tools like Koda may help older individuals learn about and feel more comfortable with ACP while potentially facilitating greater engagement in care planning.

Aging trajectories of subscales in higher-level functional capacity among community-dwelling older Japanese adults: the Otassha study.

BACKGROUND: Maintaining higher-level functional capacity is important for independent living in older age. The aging trajectory of the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) has three patterns; however, the subscale patterns are unclear. AIMS: This study aimed to clarify the aging trajectory patterns of the TMIG-IC subscales among community-dwelling older Japanese. METHODS: Participants were 3,169 community-dwelling older Japanese who participated in the 2012-2022 mail survey of the Otassha study. The aging trajectory patterns of the TMIG-IC total and subscale scores for those aged 65-90 years were identified using group-based trajectory modeling. Further, the combination frequency of the subscale trajectory patterns was determined. RESULTS: Three patterns were identified: early-onset decreasing, late-onset decreasing, and high-stable. DISCUSSION: The instrumental activities of daily living (IADL) trajectory was maintained until approximately 80 years of age; however, chronic disease prevailed the most in the early-onset decreasing pattern. The early-onset decreasing pattern of intellectual activity (IA) was present in 25% of participants, showing impaired IA from 65 years of age. The late-onset decreasing pattern of social roles (SR) was present in 30% of participants, showing a sharp decline compared to other subscales. For many people, the patterns of decrease in SR and IA overlapped. CONCLUSIONS: To maintain higher-level functional capacity, interventions that include disease management and prevention of decline in IADL and increase the awareness of the social support provided throughout old age and interventions for people with an early decline in IA should be implemented.

Gender-specific aspects of socialisation and risk of cardiovascular disease among community-dwelling older adults: a prospective cohort study using machine learning algorithms and a conventional method.

BACKGROUND: Gender influences cardiovascular disease (CVD) through norms, social relations, roles and behaviours. This study identified gender-specific aspects of socialisation associated with CVD. METHODS: A longitudinal study was conducted, involving 9936 (5,231 women and 4705 men) initially healthy, community-dwelling Australians aged 70 years or more from the ASPirin in Reducing Events in the Elderly (ASPREE) study and ASPREE Longitudinal Study of Older Persons, with a median follow-up time of 6.4 years. Variable categorisation, variable selection (using machine learning (ML) models; Elastic Net and extreme gradient boosting) and Cox-regression were employed separately by binary gender to identity socialisation factors (n=25 considered) associated with CVD. RESULTS: Different socialisation factors were identified using the ML models. In the Cox model, for both genders, being married/partnered was associated with a reduced risk of CVD (men: HR 0.76, 95% CI 0.60 to 0.96; women: HR 0.67, 95% CI 0.58 to 0.95). For men, having 3-8 relatives they felt close to and could call on for help (HR 0.76, 95% CI 0.58 to 0.99; reference <3 relatives), having 3-8 relatives they felt at ease talking with about private matters (HR 0.70, 95% CI 0.55 to 0.90; reference <3 relatives) or playing games such as chess or cards (HR 0.82, 95% CI 0.67 to 1.00) was associated with reduced risk of CVD. For women, living with others (HR 0.71, 95% CI 0.55 to 0.91) or having ≥3 friends they felt at ease talking with about private matters (HR 0.74, 95% CI 0.58 to 0.95; reference <3 friends) was associated with a lower risk of CVD. CONCLUSIONS: This study demonstrates the need to prioritise gender-specific social factors to improve cardiovascular health in older adults.

Removable dental prostheses and difficulties with chewing among frail individuals: Results from the Swiss SAPALDIA cohort.

Oral healthcare among the frail is an underestimated geriatric care element. While neglected oral health (OH) is a well-established risk factor for frailty, frailty can be a risk factor for subsequent OH problems. The cross-sectional investigation nested into the SAPALDIA sub-cohort of citizens aged 52 years and older, aims to stimulate longitudinal research into aspects that accelerate poor OH among frail individuals. The hypothesis investigated was that (pre-) frail individuals are more likely to have missing teeth replaced with removable dental prostheses (RDP) resulting in difficulties with chewing. The study included 1489 participants undergoing geriatric assessments and oral examination. The main predictor was frailty status (non-frail; pre-frail; frail), based on Fried's frailty phenotype. The main outcomes of interest were non-functional dentition (presence of ≤ 19 natural teeth), presence of any RDP and self-reported difficulties with chewing. Pre-frailty and frailty were not associated with the presence of ≤ 19 natural teeth, but were associated with a higher RDP prevalence. The presence of at least one complete denture (CD) had 1.71 fold and 2.54 folds higher odds among pre-frail and frail, respectively, compared to non-frail individuals. Frail individuals with CD reported chewing difficulties 7.8 times more often than non-frail individuals without CD. The results are in line with the hypothesis that (pre-) frail individuals may be more likely to have tooth loss restored by RDPs. Future longitudinal research needs to assess potential barriers to oral hygiene and fixed dental prostheses among (pre-) frail and to study their oral health-related quality of life.

Profiles of centenarians' functioning: linking functional and cognitive capacity with depressive symptoms.

BACKGROUND: Despite most centenarians facing age-related declines in functional and cognitive capacities, the severity of these declines varies among individuals, as does the maintenance of good mental health (e.g., depressive symptoms) despite these declines. This study aims to examine this heterogeneity in centenarians from the Second Heidelberg Centenarian Study, which collected data from 112 centenarians living in Germany. In our study, we focus on a subsample of 73 centenarians who provided self-reports for our measures of interest (M age = 100.4, SD age = 0.55). METHODS: We examined correlations between functional capacity (i.e., PADL, IADL), cognitive capacity (i.e., MMSE), and depressive symptoms (i.e., GDS), and the existence of different profiles using hierarchical clustering. RESULTS: Higher functional capacity was related to higher cognitive capacity and to fewer depressive symptoms. Yet, higher cognitive capacity was associated with more depressive symptoms. Hierarchical clustering analysis elucidated this contradiction by identifying three profiles: low-capacity individuals (i.e., 24 individuals had low functional and cognitive capacities, with low depressive symptoms), high-capacity individuals (i.e., 33 individuals with high functional and cognitive capacities, with low depressive symptoms), and low-functional-high-cognitive-capacity individuals (i.e., 16 individuals showed low functional but high cognitive capacity, with high depressive symptoms). Our post-hoc analyses highlighted arthritis and pain as risk factors for functional dependence and depression. CONCLUSIONS: Our findings emphasize the importance of identifying centenarian subgroups with specific resource- and risk profiles to better address their needs, and of treating pain to improve functional capacity and mental health in centenarians.
