        <description><![CDATA[ObjectiveMedication adherence in older adults with chronic diseases is a public health challenge, given the growing and irreversible aging of the population, with direct repercussions on clinical outcomes and collective wellbeing. This scope review seeks to identify the main barriers and facilitators of pharmacological adherence and effective evidence-based interventions to optimize it.MethodsA scope review was conducted for the period 2015–2025. Forty-one observational and interventional scientific studies (clinical trials) were selected from PubMed, Scopus, Web of Science, and ScienceDirect. Initially, a search was performed in six databases covering public health, medicine, life sciences, and biomedicine (PubMed and ScienceDirect), evidence-based healthcare (Cochrane Library), social sciences, arts, and humanities (Scopus and Web of Science), and research output, with an emphasis on Latin America, Spain, and Portugal. The four databases with the largest number of publications on the older adult population were selected, including topics such as medication adherence (compliance with pharmacological treatment and prescribing recommendations), medication persistence (uninterrupted continuity in medication recovery and administration), and patient prioritization interventions using automated mechanisms. The final selection of articles was carried out by three experts, who performed a critical appraisal of the evidence. The discrepancies were resolved by two other researchers, following the identification, screening, selection and inclusion phases of the PRISMA-2020 guidelines. The analysis of the information was carried out through synthesis and narrative integration.ResultsIndividual barriers were identified, including demographic (age, sex, educational level, and income), psychological (anxiety, depression, and self-efficacy), cultural (beliefs, fatalism, and stigmas), physical and mental health status (multimorbidity and cognitive impairment), and pharmacological (number of medications and adverse effects) factors. Facilitators identified are related to the health system (continuity of care, fragmentation of care, assertive communication, access, and provision of medicines). The interventions include personalized health education.ConclusionMedication adherence in older adults should be addressed with comprehensive and sustainable interventions. These interventions combine pharmacist education, technological support, continuous monitoring, and patient participation in therapeutic decision-making. Strategies should be designed with a collaborative approach involving patients, families, and healthcare professionals, ensuring measurable clinical outcomes and improving their quality of life.]]></description>

        <description><![CDATA[Progressive supranuclear palsy (PSP) is a tauopathy and has a multifactorial etiology. The genetic component comprises at least 15 genes with unrelated functions that increase risk for PSP with a high degree of certainty. The function of these genes in increasing risk for PSP is presently unknown. This study was undertaken to identify new pathological pathways of these genes/proteins in increasing risk for PSP. Identification of possible targets and pathways of these genes was investigated using publicly available databases. 13 out of 15 of the risk genes, i.e. MAPT, KANSL1, PLEKHM1, STX6, MOBP, EIF2AK3, DUSP10, APOE, RUNX2, TRIM11, NFASC, CNTN2, and LRRK2 target microtubules, and directly alter their function via variable mechanisms. We now present data that these pathways are predicted to involve common pathways strongly involving microtubule hemeostasis, such as vesicle transport of misfolded proteins to lysosomes and cellular export. Two genes (SLCO1A2 and C4A) are not obviously directly targeting microtubules. Mutations of the risk genes interfere with microtubular function and/or structure as they relate to axon formation/integrity, axon transport, intracellular organelle transport and communication, and cellular, microtubule - guided waste management. Microtubules may be thought of as a conveyor belt for the distribution of nutrients and waste management. Taken together these alterations include an increased risk of tau precipitation (MAPT) and are molecular drivers of neuronal degeneration in PSP. Although microtubular dysfunction has long been documented in PSP mainly based on the findings related to MAPT, this is the first study of the effect of risk genes in PSP. We demonstrate that most of these genes (13/15) also affect microtubular structure and function. These genes/proteins may also be biased towards neurodegeneration in motor neurons.]]></description>

        <description><![CDATA[IntroductionThe purpose of this manuscript is to report on the development of the SIRS (Social Isolation Risk Scale), a brief screening tool to identify HNC survivors at risk for social isolation through assessing for the presence of multiple potential causes from which this risk might arise.MethodThe development of the SIRS occurred in two phases. During the first phase, item generation, the research team leveraged inductive and deductive methods to generate an exhaustive pool of potential scale items based on those in the extent literature and on the opinions of experts in HNC. During the second phase of development, item refinement, we conducted one-to-one interviews with 22 socially isolated HNC survivors. During analyses, items endorsed by 7 or more participants on the checklist were retained. Retained items were reorganized from most impactful to least impactful. General items (i.e., those concerns that were not specific to only HNC survivors, e.g., chemotherapy fatigue) were removed. The remaining items were reorganized so that items with similar content were placed together.ResultsThe item generation phase yielded 39 potential items for the SIRS. These 39 items were reviewed during the item refinement phase by a sample of N = 22 HNC survivors. On average, they were 66.41 years old (SD = 9.04 years), and mostly male (n = 17, 77%). Participants were an average of 3.18 years (SD = 4.81 years) since completing treatment. Of the 39 items, 29 were endorsed by 7 or more HNC survivors and retained. Of the list of 29 items, 16 additional items were removed, as they were not specific to HNC. The remaining 13 items, which were reorganized so that items of similar content were adjacent to each other, composed the SIRS. The stem questions and the Likert-scale response options used during the item refinement phase were retained for the final SIRS.ConclusionAs a first of its kind, SIRS is a brief screening tool for use in busy clinical environments to characterize risk for social isolation in HNC survivors. It was developed through rigorous psychometric methodology including both item generation and refinement phases.]]></description>

        <description><![CDATA[IntroductionCancer survivors and intimate care partners coping with cancer may each experience loneliness that impacts their health, but research within couples and potential benefit of interventions is scarce. METHODS: We added the Cancer Loneliness (CL) scale to measures of anxiety, depressive symptoms, pain and social and physical function mid-way through the Exercising Together trial (NCT03630354) in couples coping with breast (BC; n = 44) or prostate cancer (PC; n = 75). The prevalence of CL scores >1 indicated at least some loneliness and we ran correlations between CL and measures of social, physical and mental health. Within PC couples we explored the potential benefits of different types of dyadic exercise programs (supervised, group partnered exercise, supervised separate groups of survivors or partners, or unsupervised independent exercise) on CL over 6 months.Results96% of breast cancer survivors (BCS) and 77% of prostate cancer survivors (PCS) reported CL at baseline. CL was positively associated with anxiety (rho = 0.44, 0.77), depressive symptoms (rho = 0.60, 0.67) and pain (rho = 0.34, 0.23) and inversely associated with social functioning (rho = −0.54, −0.55) among BCS and PCS, respectively (all p < 0.01). CL was inversely associated with physical functioning in BCS (rho = −0.35), but not PCS. Among care partners, 74%–77% of care partners for each BCS and PCS reported CL related to their partner’s cancer at baseline. CL was positively associated with anxiety (rho = 0.43, 0.30) and depressive symptoms (rho = 0.62, 0.45) among BC and PC care partners, respectively (all p < 0.01). CL was inversely associated with social functioning in BC partners only (rho = −0.45, p < 0.01), but not with physical functioning in either group. Within PC couples, there was a significant (inverse) interaction between change in CL over six-months of exercise and baseline loneliness. Declines in CL for both PCS and care partners were steepest in the exercise program where they trained with other PCS or care partners.ConclusionRelationships may not offer enough social support to avoid feelings of loneliness associated with cancer that in turn affects the physical, emotional and social health of each partner. However, exercise may help rebuild connection within the couple and be an avenue for informal social support that together could reduce loneliness.Clinical Trial Registration[clinicaltrials.gov]: identifier, [NCT03630354].]]></description>

        <description><![CDATA[IntroductionOlder persons who are temporarily non-ambulant are often confronted with the adverse health effects of physical inactivity. These adverse health effects include sarcopenia, reduced strength, reduced health-related quality of life and increased mortality. To counteract those negative effects of immobility, it is important to know how older persons can stay physically active when they are temporarily unable to ambulate. Therefore, the aim of this scoping review was to provide an overview of physical activity interventions that can be performed by older persons who are temporarily non-ambulant.MethodA literature search was performed through PubMed, EMCARE, EMBASE, CINAHL, Web of Science, Cochrane Library, PEDro, Academic search premier and Epistemonikos in August 2023 and updated in October 2024 and December 2025. Included were full-text, English-language articles, describing physical activity interventions for older persons who were temporarily non-ambulant.ResultsTen studies met the inclusion criteria. The physical activity interventions described in the studies were wheelchair mobilization, lower extremity strength training, (seated) physical activity programmes and neuromuscular electric stimulation. The effects of these interventions on physical fitness include; the ability to ambulate and walk, increase in muscle mass and power, slower decline in physical activity and a decrease in fear of falling.Conclusion and implicationsStudies regarding physical activity interventions that can be performed by older persons who are temporarily non-ambulant are scarce, even though being temporarily non-ambulant is common among older persons. This review highlights the need for future studies on how we can help temporarily non-ambulant older persons to remain physically active. We recommend to conduct future studies for the development of a hospital and in-patient geriatric rehabilitation guideline for those older persons.]]></description>

        <description><![CDATA[BackgroundThe increasing prevalence of age-related chronic diseases, driven by the aging population, poses substantial medical and economic challenges. Emerging researches have underscored the crucial roles of gut microbiota and bile acids (BAs) in metabolic and physiological functions regulation.Methods100 elderly and 100 young participants were enrolled in this study. Fecal and serum BAs were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS), while gut microbiota composition was assessed through 16S rRNA gene sequencing. Cytokine levels were measured by Enzyme-Linked Immunosorbent Assay (ELISA).ResultsElderly participants exhibited significantly lower levels of primary fecal BAs, particularly cholic acid (CA) and chenodeoxycholic acid (CDCA), alongside an increase in secondary BAs such as lithocholic acid (LCA), leading to a marked reduction in the primary/secondary BAs ratio. Serum showed a decline in both conjugated and unconjugated BAs, primary/secondary BAs ratio, while a notable rise in 12α-OH/non-12α-OH BAs. Furthermore, increased levels of P21, LPS, IL-6, and TNF-α in the elderly were associated with specific BA changes, including reduced fecal unconjugated primary BAs and increased LCA. Significant differences in gut microbiota composition were observed, with the elderly displaying a higher abundance of microbiota capable of 7α-dehydroxylation. Correlations were observed among BAs, gut microbiota alterations, and markers of chronic inflammation and intestinal barrier dysfunction.ConclusionAging is associated with significant changes in the BA pool, which are associated with gut microbiota dysbiosis. These alterations may be related to intestinal barrier dysfunction and chronic low-grade inflammation. Modulating BA metabolism presents a potential strategy for mitigating the aging process. Due to the cross-sectional design, causal relationships cannot be established.]]></description>

        <description><![CDATA[BackgroundWith the rapid aging of the global population, the wellbeing of urban-dwelling older adults living alone is linked to increasing research attention.MethodsData were derived from the 2017–2018 wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). A sample of 1,261 urban-dwelling older adults living alone was analyzed. Sleep quality, depression, cognitive function, and life satisfaction were assessed. Parallel mediation analysis was conducted using the PROCESS macro (Model 4) with 5,000 bootstrap samples. To validate the robustness of the mediation model, a 5-fold cross-validation procedure was performed, ensuring the stability and association consistency of the indirect effects.ResultsPoor sleep quality was significantly associated with higher depression scores and lower cognitive function, both of which were negatively associated with life satisfaction. The mediation analysis revealed that depression and cognitive function independently mediated the relationship between sleep quality and life satisfaction, with depression was associated with a significantly stronger indirect effect (20.22% of total effect) than cognitive function (2.52%). The cross-validated estimates closely matched the full-sample results, confirming model stability.ConclusionThese findings highlight the crucial role of sleep quality in enhancing life satisfaction among urban solitary older adults, primarily in association with the reduction of depressive symptoms. The study highlights the need for community-based interventions integrating sleep hygiene and depression screening, which is particularly relevant to women living alone.]]></description>

        <description><![CDATA[IntroductionAging is accompanied by changes in lipid metabolism that may influence cellular homeostasis and risk for age-related disease. Circulating polyunsaturated fatty acid (PUFA) status is increasingly recognized as an important marker of metabolic health and may shift with age. Product-to-precursor ratios of fatty acids, including PUFA are commonly used as proxy indices of desaturation and elongation but do not directly reflect enzyme activity.MethodsIn this cross-sectional study, plasma and erythrocyte fatty acid profiles were measured by gas chromatography–flame ionization detection (GC-FID) in patients (n = 1277) from a metabolic disease clinic in Brandenburg, Germany. Participants were stratified into five age groups (≤ 34, 35–44, 45–54, 55–64, ≥ 65 years) and differences between groups were assessed using statistical tests.ResultsParticipants aged ≥ 65 years had higher total omega-3 (n-3) and lower total omega-6 (n-6) PUFA levels in both matrices. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) increased with age, whereas linoleic acid (LA) and dihomo-gamma-linolenic acid (DGLA) decreased. Ratio-based indices showed consistent age associations. The delta-5-desaturase index (D5D) and arachidonic acid (AA)/LA ratio were positively associated with age, while elongation of very long chain fatty acids (ELOVL)2 and ELOVL6 were inversely associated.DiscussionOverall, blood PUFA profiles and multiple ratio-based indices showed consistent, age-related trends in this clinical cohort. Interpretation is limited by the cross-sectional design and the lack of key determinants of PUFA status (e.g., diet, clinical covariates, genetic information and gut/microbiome factors). Nevertheless, these results underscore age-related shifts in PUFA composition and enzymatic proxy indices, providing new insights into lipid metabolism across the lifespan.]]></description>

        <description><![CDATA[Inflammation repairs tissues in response to stressors. Aging alters circulating pro- and anti-inflammatory markers through immunosenescence, the gradual decline of immune function, and increased cytokine secretion, contributing to chronic inflammation. Exercise can modulate cytokine levels, producing anti-inflammatory effects. However, how age and sex influence these responses remains unclear. Methods: We evaluated blood serum levels of proinflammatory (TNF-α, IL-1β, IL-6) and anti-inflammatory (IL-10) cytokines in young and old male and female Fischer 344 rats before and after a moderate treadmill exercise protocol. Results: TNF-α increased in young rats following both sedentary and exercise treatments, but not in old rats, with no sex differences. Exercise increased IL-1β and IL-6 only in young males, while old males showed elevated levels under sedentary condition that were suppressed by exercise. IL-10 increased exclusively in old females after exercise. Conclusion: These results indicate that exercise does not uniformly suppress inflammation but modulates cytokine activity in an age- and sex-dependent manner. In young rats, proinflammatory responses may support tissue repair and muscle remodeling, whereas in old rats, the attenuation of these markers, along with IL-10 elevation in females, suggests a shift toward anti-inflammatory adaptations that may counteract chronic inflammation.]]></description>

        <description><![CDATA[Stroke survivors face a substantially increased risk of hip fractures due to a combination of motor impairments, falls, and stroke-induced bone density loss. Conversely, hip fractures in this population are associated with elevated mortality, reduced functional recovery, and greater healthcare burden. This narrative review synthesizes current evidence on the epidemiological, pathophysiological, and clinical interrelationships between stroke and hip fractures. Key quantitative findings include a 7.6% incidence of hip fractures within 5 years post-stroke—significantly higher than the 2.8% observed in non-stroke populations—and a 30-day postoperative mortality rate of up to 14.8% in stroke patients with hip fractures. Severe post-stroke disability is associated with a 2.1- to 4.8-fold increased risk of hip fracture compared to those with good recovery. The review also highlights the utility of risk assessment tools such as FRAX and emerging prediction models, and evaluates prevention strategies including osteoporosis screening, exercise-based rehabilitation, and lifestyle modifications.]]></description>

        <description><![CDATA[BackgroundAlzheimer’s disease (AD) is a prevalent neurodegenerative disorder characterized by progressive cognitive impairment, with the β-amyloid protein (Aβ) aggregation as a core pathological driver. As global aging intensifies, AD poses a severe public health burden, highlighting the urgency of developing effective immunotherapies. This review aims to systematically summarize the research progress of Aβ-targeted AD vaccines, from first-generation approaches to next-generation strategies, and discuss key challenges and future directions for clinical translation.MethodsA comprehensive literature search was conducted across PubMed, Web of Science, the Cochrane Library, EMBASE, and Google Scholar up to 14 November 2025. Relevant studies were selected using predefined eligibility criteria, focusing on Aβ-targeted AD vaccines’ development, mechanisms, preclinical efficacy, and clinical outcomes. Review articles and meta-analyses were included, while case reports and non-Aβ-targeted studies were excluded. Data extraction and synthesis focused on vaccine strategies, immune mechanisms, and translational challenges.ResultsFirst-generation Aβ vaccine (e.g., AN-1792) showed preclinical promise but failed clinically due to autoimmune complications. Next-generation vaccines, including peptide/epitope vaccines, DNA vaccines, viral vector vaccines, and protein self-assembling vaccines, have been developed to induce protective Th2-biased immune responses while avoiding harmful T-cell reactions. Preclinical studies demonstrate reduced Aβ deposition and improved cognitive function, with several candidates advancing to clinical trials showing favorable safety and immunogenicity. Key mechanisms include Fc receptor-mediated phagocytosis, antibody-mediated fibril disaggregation, and the peripheral Aβ sink effect.ConclusionAβ-targeted AD vaccines have evolved toward safer and more effective designs, with multiple strategies showing translational potential. Challenges remain, including blood-brain barrier (BBB) penetration, immune response modulation, and defining optimal therapeutic time windows. Future research should focus on personalized vaccines, combination therapies, and novel antigen delivery platforms to fully realize the clinical potential of AD immunotherapies.]]></description>

        <description><![CDATA[BackgroundPercutaneous curved kyphoplasty (PCKP) demonstrates early advantages in treating osteoporotic vertebral compression fractures (OVCFs), but its long-term efficacy and patient-selection criteria remain controversial.ObjectiveThe aim of this study is to prospectively compare the mid-to-long-term outcomes of PCKP versus unilateral percutaneous kyphoplasty (UPKP) for single-level OVCFs and establish a hierarchical decision model based on vertebral compression severity.MethodsA total of 139 patients with single-level OVCFs (January 2021–January 2023) were randomized to PCKP (n = 67) or UPKP (n = 72), with ≥24-month follow-up. Outcomes included the visual analog score (VAS), Oswestry dysfunction index (ODI), cement distribution (type I–V classification), leakage rate, and re-fracture incidence. Anti-osteoporosis compliance was analyzed for its impact on efficacy.ResultsBoth groups showed significant postoperative improvement in VAS and ODI (p < 0.05). PCKP achieved superior early pain relief (VAS: 1.99 ± 0.77 vs. 3.47 ± 0.50; ODI: 27.07 ± 1.78 vs. 35.33 ± 3.12 at 2 days, p < 0.001), a higher cement distribution excellence rate (91.04% vs. 76.39%), and a lower leakage rate (10.45% vs. 26.39%). However, outcomes converged from 3 months onward (p > 0.05), with no significant differences in re-fracture (11.94% vs. 15.28%) or anti-osteoporosis compliance (28.36% vs. 33.33%). Subgroup analysis revealed that PCKP provided more symmetric cement distribution (p = 0.02) and a 21% lower leakage risk in moderate-to-severe OVCFs (Genant 2–3).ConclusionPCKP enhances early biomechanical stability in moderate-to-severe OVCFs through optimized cement dispersion, while long-term efficacy relies on standardized anti-osteoporosis therapy. A stepwise decision model (“PCKP for Genant 2–3, UPKP for mild cases”), combined with a “vertebral augmentation–bone metabolism modulation–behavioral intervention” strategy, is recommended.]]></description>

        <description><![CDATA[BackgroundPeptide therapeutics represent an emerging frontier in gerontological medicine, targeting fundamental hallmarks of aging including metabolic dysfunction, telomere attrition, tissue repair impairment, and hormonal decline.ObjectiveTo comprehensively review the mechanisms, clinical applications, evidence base, and safety profiles of therapeutic peptides with demonstrated or potential applications in healthy aging and age-related conditions.MethodsA comprehensive narrative review was conducted through systematic searches of PubMed, Scopus, and regulatory databases (FDA, WADA) from inception through January 2026. Search terms included “peptide therapeutics,” “aging,” “gerontology,” “healthspan,” combined with specific peptide names (tirzepatide, epitalon, GHK-Cu, BPC-157, TB-500, Semax, CJC-1295, ipamorelin, bremelanotide). Peer-reviewed articles, clinical trials, regulatory documents, and preclinical studies were evaluated. A total of 20 primary sources were selected based on relevance, methodological quality, and contribution to understanding peptide mechanisms and clinical outcomes in aging populations.ResultsNine peptides were identified spanning diverse aging interventions: metabolic restoration (tirzepatide), telomere biology (epitalon), dermal regeneration (GHK-Cu), tissue repair (BPC-157, TB-500), neuroprotection (Semax), growth hormone modulation (CJC-1295, ipamorelin), and sexual function (bremelanotide). FDA-approved agents demonstrated robust safety profiles from large-scale trials. Non-approved peptides showed promising preclinical and limited clinical evidence but lack long-term safety data and systematic validation. Significant knowledge gaps include optimal dosing regimens, combination therapy effects, and biomarkers for monitoring efficacy.ConclusionTherapeutic peptides offer mechanistically diverse approaches to multiple aging hallmarks. While FDA-approved agents demonstrate clinical potential, investigational peptides require rigorous validation through well-designed clinical trials to establish safety and efficacy for healthspan extension.]]></description>

        <description><![CDATA[IntroductionFrailty reflects age-related decline across multiple physiological systems, reducing resilience and increasing risks of falls, hospitalization, disability, and mortality. Scalable approaches are needed to identify pre-frailty earlier in community-dwelling older adults and enable timely prevention in primary care.ObjectiveTo develop and evaluate a multivariable sensor-based framework for early frailty detection using standardized gait and balance assessments in general practice.MethodsWe conducted a prospective cohort study (2021–2024) in southern Réunion Island among retired adults aged ≥65 years recruited in primary care. The protocol included: (1) baseline general practitioner (GP) assessment with expert frailty rating, Fried phenotype, and WHO ICOPE Step 1; (2) telephone assessment of mental health, self-rated health, and quality of life; (3) outpatient instrumented evaluation combining IMU-based gait analysis, force-platform posturography, grip strength, and ICOPE Step 2 measures; (4) monthly falls surveillance over 6 months; and (5) repeat instrumented gait and balance assessment at 6 months. Correlation analyses and machine-learning models examined relationships between frailty measures and the discriminative value of sensor-derived and multimodal predictors.ResultsAmong 145 participants (mean age 71 ± 5 years), 98.5% had impairment in at least one intrinsic capacity domain at baseline, most commonly vision (77.7%), locomotion (53.1%), hearing (52.5%), and psychological (27.3%). Sedentary behavior was frequent (77%). Expert frailty scores correlated with the Fried phenotype, whereas associations with self-rated health were weaker. Models based on sensor parameters alone showed limited ability to reproduce Fried-defined frailty, while multimodal models integrating clinical and questionnaire variables improved discrimination. Over 6 months, kinesiotherapy and regular physical activity were associated with improved postural control metrics (including center-of-pressure features and mediolateral sway), while changes in gait speed were modest.ConclusionAn IoT-supported platform combining quantitative gait, balance, and grip strength measures with targeted questionnaires is feasible in outpatient primary care and yields frailty estimates broadly consistent with GP assessment. However, subjective and clinical inputs remain essential to capture psychological aspects of frailty not fully reflected by sensor signals alone. These findings support scalable frailty screening and longitudinal monitoring, and warrant validation in larger samples, including deployment by trained non-medical personnel and integration into precision-prevention pathways.]]></description>

        <description><![CDATA[It has been well-established that social isolation, loneliness, and inadequate social support are critical determinants of psychological and physical outcomes in persons with cancer. In contrast to latent variable analysis, upon which most current research is based, psychometric network analysis offers a framework for understanding how these social factors relate to specific symptoms, coping resources, and wellbeing in the context of cancer. Although very few studies in this area of research have used network analysis methods, this presentation focuses on a small number of recent network-analytic studies in oncology and other related examples, emphasizing methodological choices, stability procedures, interpretation of centrality indicators, and global network analyses. In addition, recommendations are presented for future research, such as longitudinal models, network analysis of interventions, and multifaceted data integration that might inform translational work in psycho-oncology. Psychometric network analysis holds strong potential to advance psychosocial oncology through the identification of specific modifiable targets that might help mitigate social isolation, loneliness, and inadequate support.]]></description>

        <description><![CDATA[BackgroundCardiovascular diseases (CVDs) are the leading cause of death worldwide. Although their prevalence increases with age, their impact on centenarians remains poorly understood.MethodsWe analyzed Electronic Health Records (EHRs) to assess the incidence and effect of CVDs in centenarians (n = 649) and non-centenarians (n = 62,753) in the Basque Country. Descriptive statistics were applied to discern differences between the two population groups in terms of prevalence, number of diagnoses, and treatments. Survival analysis was performed through Kaplan-Meier estimator. Trajectories of laboratory parameters were explored through non-linear mixed models (NLMMs).ResultsCentenarians had lower incidence of severe conditions such as ischemic heart disease, despite overall CVD incidence being similar between groups. Survival analyses revealed extended longevity in centenarians after both first and last CVD diagnosis. Biomarker trajectories suggested favorable biological profiles with greater resilience and faster recovery in centenarians.ConclusionDespite experiencing CVDs, centenarians demonstrate delayed onset, reduced severity, and more favorable biological recovery compared to non-centenarians. These findings indicate potential resilience mechanisms that may contribute to healthy ageing.]]></description>

        <description><![CDATA[PurposeFalls cause serious injuries with partially long immobilization time and decreased quality of life in older adults. The risk factors comprise instability in gait and balance, which were moderately correlated with the strength capacity. While the literature focused on upper-limb strength, in this work, we sought to evaluate the relationship between maximal plantar flexion and dorsiflexion strength and walking and balance parameters in older adults.MethodsA total of 51 healthy and active participants (age: 78.5 ± 5.8 years) participated in the study. Lower-leg maximal strength was determined isometrically. Selected gait parameters (normal and maximal walking velocity), static balance [center of pressure (CoP) sway in different standing conditions], and the timed up and go (TUG) and sit-to-stand (STS) were determined. Correlations [Pearson (rp)/Spearman (rs)] were calculated in general and stratified by sex.ResultsWalking velocity, STS, and TUG were significantly influenced by lower-leg strength (rs up to 0.79 in males). Static balance showed no meaningful relationships. In general, fewer correlations in female participants reached the level of significance and showed smaller effect sizes.DiscussionAlthough smaller sex-subgroup sample sizes might limit confidence in the results, male participants showed higher correlations between strength and walking velocity (up to rs = 0.79) and individual balance parameters (rs = 0.77) than female participants (rs = 0.56 for gait, rs = 0.72 for TUG). The results align with previous studies showing a potential influence of strength on gait parameters; however, a causal relationship must be confirmed by longitudinal study designs. Nevertheless, based on the results, there is a need for future sex-specific studies on the necessity of sex-specific balance and fall-prevention routines.]]></description>

        <description><![CDATA[IntroductionExercise programs implemented among older adults have been extensively demonstrated to yield significant benefits; however, there is a limited body of research addressing the application of such interventions in older adults with severe or profound intellectual disabilities. This study aims to explore the effects of a structured physical exercise program on fall-risk indicators and balance-related outcomes in institutionalized older adults, both with and without intellectual disabilities.MethodsThis pre–post quasi-experimental study included 56 institutionalized older adults, of whom 32 had an intellectual disability. Participants completed a 12-week structured physical exercise program targeting balance, lower-limb strength, gait pattern, and coordination. The primary hypothesis was that the program would be associated with improvements in validated fall-risk indicators within both groups.ResultsAmong participants with intellectual disabilities, significant improvements were observed in lower-limb strength (p < 0.001) and aerobic capacity, with a 12% increase in performance on the 6-Minute Walk Test (p < 0.001). In participants without intellectual disabilities, significant improvements were observed in balance and handgrip strength. Between-group differences were limited after adjustment for baseline values and age.ConclusionThe intervention was associated with improvements in validated fall-risk functional indicators in institutionalized older adults with and without intellectual disabilities. However, due to baseline heterogeneity and the quasi-experimental design, the findings should be interpreted as preliminary and hypothesis-generating rather than confirmatory of equivalent effectiveness.]]></description>

        <description><![CDATA[PurposeNoninvasive quantitative assessment of hip musculature is critically needed, as the structural integrity of hip muscles and the degree of intramuscular fat infiltration are essential determinants of hip stability and function. This study employed a modified DIXON of magnetic resonance imaging (MRI) technique to evaluate the cross sectional area (CSA) and intramuscular fat fraction (IMFF) of hip muscles. We analyzed factors influencing changes in hip muscle structure and intramuscular fat infiltration with the aim of establishing a comprehensive map of hip muscle characteristics.MethodsThis cross-sectional study enrolled participants from the health examination center of our research institution. All participants underwent 3.0T MRI with mDIXON Quant sequence. The CSA and IMFF of 10 muscles of hip were semi-automatically delineated and measured at four predefined anatomical levels. the effects of sex, age, and laterality on hip muscle CSA and IMFF were investigated. Multivariate analysis was also performed to identify factors influencing IMFF in the hip.ResultsA total of 177 participants (100 males, 77 females; age range: 18–80 years) were included. The mean age was 52.70 ± 14.36 years for males and 51.58 ± 14.85 years for females. Compared with females, males exhibited significantly smaller subcutaneous fat area (SFA)/subcutaneous fat thickness (SFT) (p < 0.001) and a larger proximal femoral area (PFA) in the hip (p < 0.001). Additionally, males demonstrated larger CSA in all muscles (p < 0.001) and lower IMFF in most muscles (p ≤ 0.001) of hip. With advancing age, the CSA of all 10 hip muscles progressively decreased, while IMFF increased. Laterality had minimal influence on hip muscle CSA and IMFF. Multivariate analyses showed that age as the predominant factor influencing IMFF.ConclusionThe mDIXON QUANT sequence enables noninvasive quantification of CSA and IMFF of hip muscles, with age identified as a significant influencing factor. This technique holds promise for establishing normative reference data on hip muscle CSA and IMFF in healthy populations, thereby enhancing the understanding of degenerative changes and aiding in clinical decision-making for surgical planning and postoperative rehabilitation guidance.]]></description>
