Background: Oral health is an often-overlooked component of healthy ageing, as a sign of cumulative functional decline. This study explored the association between oral functional status and all-cause mortality. Methods: This was a secondary analysis of the 2016–2017 Chilean National Health Survey linked to mortality records through December 31, 2022. In total, 223 participants aged ≥ 60 years were included (N = 1,016,557). Minimum dentition (MD) was defined as ≥10 teeth, prosthesis use was self-reported, and frailty was assessed using a modified Fried phenotype. Survey-weighted Cox models estimated associations with all-cause mortality, adjusting for age, sex, area, education, frailty, diabetes, and hypertension. Results: In the survey-weighted Cox model, each category representing MD and/or prosthesis use was associated with lower mortality hazards compared with the reference group (<10 teeth and no prostheses): prostheses only (HR 0.17, 95% CI 0.05–0.61), MD only (HR 0.16, 95% CI 0.04–0.74), and MD with prostheses (HR 0.08, 95% CI 0.01–0.46). Increasing age and rural residence were associated with higher mortality hazards, whereas estimates for sex, education, frailty, diabetes and hypertension were imprecise and generally compatible with no clear association. Conclusions: These findings are hypothesis-generating and support further evaluation of oral functional status as a marker of broader health vulnerability in aged Chileans. Full article

Delayed recovery of oral intake is common in hospitalized patients with pneumonia, particularly among older adults with reduced physical activity. Despite the recent emphasis on early mobilization, the relationship between the timing of first mobilization and recovery of oral intake function remains unclear. Thus, this retrospective cohort study investigated the association between time to first mobilization and recovery of oral intake in patients hospitalized with pneumonia. We analyzed 431 admitted patients with pneumonia, including aspiration pneumonia and coronavirus disease 2019 pneumonia, at two institutions. The Functional Oral Intake Scale ≥ 4 (partial oral intake recovery) was designated as the primary outcome. The main exposure was the number of days from admission to first mobilization. Multivariable Cox proportional hazards models were used after appropriate adjustments. The median time to first mobilization was 4 days (IQR: 2–14 days). Longer time to first mobilization was significantly associated with delayed recovery of oral intake (HR: 0.96, 95% CI: 0.94–0.98, p < 0.001). Thus, early mobilization may promote the recovery of oral intake in patients with pneumonia. These findings suggest that avoiding excessive delays in mobilization may support the recovery of oral intake and swallowing function in hospitalized patients with pneumonia. Full article

Frailty is a multifactorial geriatric syndrome marked by reduced physiological reserves and increased vulnerability to adverse outcomes. This multicenter observational study adopted a One Health approach to examine the association between frailty and biological sex, denture use, and antidepressant medication, as well as their impact on bite force, in two transnational cohorts of physically active older adults. The sample included 499 individuals aged ≥60 years (295 from Brazil and 204 from Portugal), all with functional dentition and regular physical activity. Frailty was assessed using the adapted Fried phenotype and classified as non-frail (G0), pre-frail (G1), or frail (G2). Oral health, depressive symptoms (CES-D), bite force, and self-reported use of dentures and antidepressants were analyzed. Frailty was significantly associated with biological sex (p < 0.001), with higher prevalence among women, especially in G2. Antidepressant use was associated with frailty in the Portuguese cohort (p < 0.001) and in the total sample (p = 0.005), but not in Brazil. No significant association was observed between denture use and frailty. However, Brazilian participants without dentures showed significantly higher bite force (p < 0.001), indicating a functional oral health effect. Frailty was associated with female sex and antidepressant use, while bite force emerged as a complementary functional marker for geriatric assessment. Full article

The oral cavity performs several functions that are essential for sustaining life and carrying out daily activities. Given the importance of maintaining functional abilities for healthy aging, exploration of the adverse health outcomes that may result from impaired oral function is needed. This cross-sectional study examined oral functional status in 176 community-dwelling older adults with preserved cognitive function and activities of daily living, and analyzed the association between oral hypofunction and physical frailty. Oral hypofunction was diagnosed using seven parameters. Frailty was assessed using the Korean version of the Fried Frailty Phenotype, which focuses on physical characteristics. Independent t-tests, one-way analysis of variance, the Kruskal–Wallis test, and multiple logistic regression analysis were conducted to examine the association between oral hypofunction and frailty. The prevalences of oral hypofunction and physical frailty were approximately 48% (n = 85) and 40% (n = 71), respectively. After adjusting for frailty-related factors, including sociodemographic and health-related characteristics, higher oral hypofunction scores were associated with an increased likelihood of physical frailty (odds ratio, 1.382; 95% confidence interval, 1.017–1.876). These findings suggest that maintaining the various functions of the oral cavity, including mastication, within normal ranges and restoring impaired oral abilities as early as possible may be relevant to healthy aging.

Background: Malnutrition and its risk are prevalent in older adults and contribute to frailty, morbidity, and mortality. Poor oral health—particularly tooth loss and inadequate prosthetic rehabilitation—may impair chewing, limit dietary variety, and accelerate nutritional decline. We investigated associations between dentition status, denture use, and nutritional status in a nationally representative sample of Polish older adults. Methods: We analyzed data from 5214 participants aged ≥60 years from the nationwide cross-sectional PolSenior2 study. Dentition status was classified as functional dentition (≥20 teeth), partial dentition (1–19 teeth), or edentulism (0 teeth). Nutritional status was assessed using the Mini Nutritional Assessment—Short Form (MNA-SF); impaired nutritional status was defined as MNA-SF <12 (malnourished or at risk). Additional indicators included hypoalbuminemia (<35 g/L) and small calf circumference (<31 cm). Associations were tested using chi-square and multivariable logistic regression adjusted for age, sex, education, and place of residence. Results: Functional dentition was present in 15.5%, partial dentition in 48.1%, and edentulism in 36.4% of participants. The proportion of edentulous individuals increased across worsening MNA-SF categories (26.2% in well-nourished, 41.8% in at risk, 46.9% in malnourished). In adjusted models, edentulism was associated with higher odds of impaired nutritional status compared with functional dentition (OR: 1.66; 95% CI: 1.32–2.10; p < 0.001), while partial dentition showed a non-significant trend (OR: 1.22; 95% CI: 0.98–1.52; p = 0.077). Among edentulous participants, denture use was more common in well-nourished individuals than in those with impaired nutritional status (93.0% vs. 77.2%), suggesting a possible association between active prosthetic rehabilitation and better nutritional status. Conclusions: In Polish older adults, tooth loss—particularly edentulism—is associated with poorer nutritional status. Screening for malnutrition risk may benefit from incorporating basic oral health and denture-use assessment while improved access to prosthetic rehabilitation may support nutritional resilience in ageing populations.

Background: Oral frailty is an emerging determinant of late-life disability. While objective functional measures have been proposed as key indicators, their combined role in predicting frailty among physically active older adults remains unclear. Therefore, this study aimed to investigate the association between the presence of oral frailty and lip pressure, bite force, and denture use. Methods: This cross-sectional study included 192 participants aged 60 years or older from Brazil (n = 131) and Portugal (n = 61), all physically active and with ≥20 natural or rehabilitated teeth. Data were collected through a questionnaire on sociodemographic data and the Oral Frailty Index-8. The clinical assessment included lip pressure, bite force, and denture use. Multiple logistic regression identified independent predictors; model fit and discrimination were examined using the Hosmer–Lemeshow test and ROC curve. Results: Participants were mainly female (83.3%), mean age ≈72 years; 76% used dentures and frailty prevalence was ≈49%. Higher lip pressure (OR = 0.986, 95% CI = [0.973–0.999]) and higher bite force (OR = 0.925, 95% CI = [0.885–0.967) were independently protective, whereas denture use (OR = 6.898, 95% CI = [2.994–15.895]) markedly increased oral frailty odds. The model showed good discrimination (AUC 0.779). Conclusions: Even small increases in lip pressure and bite force reduced the likelihood of frailty, while denture use identified individuals at substantially higher risk. These findings highlight orofacial muscle strength and masticatory capacity as core components of oral frailty and support incorporating lip pressure and bite force testing into multidimensional frailty assessment and targeted rehabilitation.

Background/Objectives: Patient acceptability of oral anticancer drugs is a critical factor that influences treatment in older outpatients receiving cancer chemotherapy and plays a central role in enhancing adherence and treatment effectiveness. Identifying older outpatients receiving cancer chemotherapy who exhibit poor tablet acceptability before initiating oral anticancer therapy and offering alternative treatment options are beneficial. Therefore, we investigated the characteristics of patients with poor tablet acceptability by focusing on the tablet size, geriatric assessment, and polypharmacy. Methods: A questionnaire survey on experiences with tablet medication was conducted among patients who received chemotherapy at the Outpatient Treatment Center of Tokyo Metropolitan Bokutoh Hospital from September 2024 to September 2025. The median values of the long diameter (12 mm) and the combined length, width, and thickness (26 mm) of the tablets reported as acceptable in the questionnaire described in Method 1 were used as cutoff values. Patients whose reported acceptable tablet dimensions were below these median values were classified as “poor tablet acceptability,” whereas those with values above the median were classified as “good tablet acceptability”. Univariate and multivariate logistic regression analysis was performed to identify characteristic factors associated with poor tablet acceptability in older outpatients receiving cancer chemotherapy, with poor tablet acceptability as the dependent variable and patient sex, body mass index, Geriatric 8 score, each item of the Oral Frailty 5-item Checklist, and polypharmacy as explanatory variables. Results: 90 patients completed the questionnaire survey. Female sex and polypharmacy were independent factors associated with poor tablet acceptability in older outpatients receiving cancer chemotherapy. In addition, subjective difficulty in chewing tended to be associated with poor tablet acceptability. Conclusions: This study suggests that assessing polypharmacy and oral function, along with early multidisciplinary intervention before and during oral anticancer therapy, particularly in females, patients taking multiple medications, and those reporting difficulty in chewing, may help maintain tablet acceptability and improve adherence.

Background: Transcatheter aortic valve implantation (TAVI) is increasingly used across all risk groups, meaning more patients are living long-term with transcatheter bioprosthetic valves. These patients are often multimorbid and vulnerable to both thrombotic and bleeding complications. Optimal antithrombotic therapy remains uncertain due to differences in trial design, patient demographics, and procedural practices. Methods: We undertook a narrative review that included randomised controlled trials, observational studies, biomarker research, and guideline recommendations on post-TAVI antithrombotic therapy. We evaluated the available evidence for antiplatelet and anticoagulant strategies after TAVI, predictors of bleeding and thrombotic complications, to identify emerging approaches using biomarkers for personalised risk stratification. Results: Thrombotic events after TAVI are predominantly early and procedural in origin, while new-onset atrial fibrillation (AF) leads to substantial late risk. Subclinical leaflet thrombosis is frequent, but its clinical significance remains uncertain, as anticoagulation reduces CT-detected leaflet abnormalities without improving clinical outcomes. Early bleeding within the first 30 days remains a principal contributor to mortality, influenced by frailty, vascular access, comorbidity, and intensity of antithrombotic therapy. Randomised evidence consistently supports a minimalist, indication-driven regimen: single antiplatelet therapy for patients without an oral-anticoagulation (OAC) indication, and OAC monotherapy for those with AF. Routine OAC use in unselected patients carries no advantage and exposes them to harm. Biomarkers and machine-learning models show promise for future individualised risk assessment. Conclusions: Antithrombotic strategies post-TAVI should prioritise minimising bleeding while maintaining adequate thromboembolic protection. Single antiplatelet therapy for patients without an indication for OAC and OAC alone for those with AF offer the best balance of safety and efficacy. Ongoing trials may clarify the role of imaging-guided therapy and biomarker-based risk stratification and refine antithrombotic strategies. Full article

Stroke is a major global health concern, particularly among the elderly, who frequently present with multiple comorbidities, most notably cardiovascular diseases. Importantly, atrial fibrillation confers a nearly fivefold increase in stroke risk and accounts for up to one-quarter of ischemic strokes in older adults. Stroke is a neurological disease characterised by a strong cardiovascular interplay, and its multifactorial nature requires an integrated preventive approach. This review focuses on primary and secondary prevention in this population, with a frailty-informed perspective. We synthesise evidence on blood pressure control, lipid-lowering (including LDL-C targets), glycemic management, and antithrombotic strategies—particularly oral anticoagulation for atrial fibrillation—as well as the role of frailty indices in guiding individualised risk–benefit decisions. We also discuss practical care pathways, including structured post-discharge programs, continuity of care, and the need for multidisciplinary collaboration involving cardiologists, neurologists, and primary care. We highlight how frailty indices refine risk–benefit assessments without justifying therapeutic nihilism, and how sex- and age-related factors shape treatment effectiveness and safety. By narrowing scope and emphasising practical, multidisciplinary prevention strategies, this review aims to support clinicians in reducing recurrent events, disability, and mortality in very old patients. Future work should prioritise pragmatic trials, including those involving the oldest old and the use of standardised frailty metrics, to inform prevention decisions. Full article

Background/Objectives: Oral frailty and hypofunction in older adults are strongly associated with declines in nutritional status, physical function, swallowing ability, and overall health. Isolated interventions usually fail to achieve sufficient improvement since these conditions result from interrelated biological, psychological, and social factors. Multidisciplinary approaches combining oral management, nutritional support, and physical rehabilitation have shown promise. This narrative review synthesized evidence from 15 studies examining multifaceted interprofessional interventions across hospitals, communities, long-term care facilities, and home-care settings. Methods: A structured search of PubMed and Web of Science (2000–2025) identified original studies assessing oral, nutritional, or physical outcomes in older adults post-interprofessional interventions. Fifteen eligible studies were extracted; the findings were integrated using narrative synthesis owing to design and outcome heterogeneity. Results: Educational multidisciplinary interventions improved oral hygiene, caregiver awareness, and oral motor function. Multidisciplinary rehabilitation and multidomain programs consistently improved tongue pressure, swallowing function, mastication ability, appetite, body composition, activities of daily living, and oral intake resumption. Nutrition support team-delivered interventions reduced aspiration risks and improved oral environment and swallowing function. Community-based programs using munchy meals and combined exercises enhanced oral and physical functions. Social participation provided psychological benefits. Home-care dysphagia rehabilitation enabled 69% of tube-fed patients to resume oral intake. Conclusions: This narrative review supports a triadic, interprofessional approach in geriatric care, highlighting consistent improvements in oral function through integrated oral, nutritional, and rehabilitative interventions.

Background/Objectives: This study aimed to describe changes in physical performance and nutritional status among frail adults at risk of falls receiving muscle-targeted oral nutritional supplementation (MT-ONS) as part of routine clinical care. Methods: A prospective, open-label, single-centre, uncontrolled, descriptive study was conducted in a real-world clinical setting. Patients ≥ 70 years attending an outpatient fall clinic were consecutively recruited and assessed at baseline and after at least 90 days of MT-ONS (100% whey protein enriched with leucine and vitamin D), provided as part of a comprehensive care plan including exercise recommendations, medication review, and home adaptation advice. Sociodemographic, physical performance [Short Physical Performance Battery (SPPB)], nutritional status [Mini Nutritional Assessment-Short Form, (MNA^®-SF)], walking ability [Functional Ambulation Categories (FACs)], number of falls, muscle strength (dynamometry), body composition (Tanita), health-related quality-of-life (SF-12), functional capacity (Barthel Index), and adherence data were collected. Statistics analyses were descriptive and exploratory. Results: Twenty-six participants were assessed (58% women, age: 82.1 ± 5.4 years). Mean SPPB score increased from 7.3 (±3.6) to 8.0 (±4.0) (p = 0.3). At baseline, 35% were malnourished, 42% at risk of malnutrition, and 23% well-nourished. After ≥90 days of MT-ONS, 4% were malnourished, 54% at risk, and 42% well-nourished. The number of falls decreased from 1.2 falls/month (±0.9) to 0.2 falls/month (±0.3, p < 0.0001). Favourable changes in physical performance were positively correlated with improvements in nutritional status (p = 0.03). Adherence was high (92%), largely attributed to pleasant taste (71%) and smell (58%) and positive health perceptions (58%). Conclusions: In routine clinical practice, frail adults at risk of falls who received MT-ONS, 100% whey protein enriched with leucine and vitamin D for ≥90 days, as part of a comprehensive care plan improved their physical performance and nutritional status and reduced the number of falls. These findings should be interpreted as preliminary. Full article

Weight loss is an indicator of nutritional disorders, is associated with increased morbidity and mortality, and is more likely to be experienced by individuals with fewer teeth. In this study, we examined the relationship between 1-year body weight changes and variations in various oral function tests. In total, we examined 104 individuals aged 45–84 years (70 men and 34 women) who underwent health check-ups at our hospital in 2023 and 2024. Several oral function tests were performed, and changes over a 1-year period were compared using the Wilcoxon signed-rank test. The rate of change in oral function was compared between individuals who lost ≥5% of their body weight in 1 year and those who did not; no significant differences in body weight and oral function were observed between 2023 and 2024, and no significant differences in the rates of change in oral function or weight loss were observed based on sex and age. The rates of change in occlusal force and masticatory function were significantly correlated with weight loss rates, while no differences were observed in terms of sex or age between those who lost ≥5% of their body weight in 1 year and those who did not; the only significant difference was in occlusal force: weight loss was correlated with occlusal force over 1 year, with individuals who lost ≥5% of their body weight exhibiting significantly lower occlusal force, a risk factor for nutritional disorders.

Iron deficiency (ID) is highly prevalent in older adults and remains frequently underdiagnosed despite its relevant prognostic impact. ID may be absolute or functional and is observed across multiple geriatric clinical settings, including heart failure, chronic kidney disease, malnutrition, fragility fractures and long-term care facilities. Beyond anaemia, ID contributes to impaired mitochondrial function, reduced exercise capacity, frailty, cognitive and functional decline, increased hospitalizations and mortality. In heart failure and CKD, ID – irrespective of haemoglobin – worsens clinical outcomes. Systematic assessment of iron status should be integrated into geriatric evaluation. Oral iron therapy is often limited by poor tolerance and hepcidin-mediated malabsorption, whereas intravenous formulations show greater efficacy in selected patients. Early identification and targeted correction of ID may improve symptoms, quality of life and functional recovery in elderly populations, although further large trials in very old and frail subjects are needed.

Background/Objectives: Loneliness is a critical public health concern associated with adverse mental and physical health outcomes in later life. However, few large-scale studies have examined loneliness in relation to depression, aspiration risk, frailty, and social participation among Japanese older adults. This study examined associations between loneliness and psychosocial and health-related factors among older adults. Methods: This cross-sectional study involved a secondary analysis of data obtained from online surveys conducted in 2018 and 2021 among 1000 community-dwelling Japanese adults (≥65 years). Loneliness was assessed using the UCLA Loneliness Scale Version 3 and dichotomized at the median to define a high-loneliness group. Depressive symptoms, aspiration risk, frailty, conversation frequency, and volunteering participation were assessed using validated scales. Multivariable logistic regression was used to identify factors associated with loneliness and interaction terms were examined to assess effect modification. Results: High loneliness was observed in 52.2% of participants. Greater loneliness was significantly associated with depressive symptoms (GDS ≥ 5; OR = 4.69, 95% CI: 2.84–7.76), higher dysphagia risk (DRACE score; OR = 1.08, 95% CI: 1.00–1.16), and lower daily conversation frequency (OR = 0.76, 95% CI: 0.67–0.86); however, volunteering (OR = 0.475, 95% CI: 0.23–0.87) was a protective factor. Conclusions: Loneliness among Japanese older adults is closely linked to depressive symptoms and aspiration risk, while frequent conversations and volunteer participation appear to be protective. Community-based interventions promoting social engagement and oral health may mitigate loneliness and its health consequences and improve quality of life for older adults. Given the cross-sectional design, the observed associations should not be interpreted as causal. Full article

Background: Cognitive aging is a physiological process that involves gradual and mild changes in mental functions. When these changes significantly affect cognitive performance, it is considered cognitive decline. Objective: This analytical cross-sectional pilot study examined the association between periodontal status, systemic conditions, and cognitive performance in middle-aged and older adults. Methods: Forty adults aged 35–59 years (n = 20) and ≥60 years (n = 20) from northeastern Mexico were evaluated. Oral assessments included the Modified Gingival Index and detection of Porphyromonas gingivalis and Fusobacterium nucleatum using qPCR. Cognitive function was evaluated with the Mini-Mental State Examination (MMSE), and frailty with the Clinical Frailty Scale (CFS) and Oral Frailty Checklist (OF-5). Systemic medical history and oral hygiene habits were determined using a questionnaire. Results: MMSE scores were lower in older adults compared with middle-aged adults, and the magnitude of the difference was small. The presence of P. gingivalis or F. nucleatum was similar between groups. Frailty indicators were more prevalent in older adults. Logistic regression identified age and frailty-related variables as the strongest predictors of lower cognitive performance, whereas microbiological findings were not significant predictors. Conclusions: Age and frailty indicators, rather than bacterial presence alone, were associated with reduced cognitive performance in this pilot sample. Although no microbiological differences were observed, the findings highlight the need for larger analytical studies incorporating quantitative bacterial load and additional confounders to better understand the oral–systemic–cognitive interactions.
