Objective: We aimed to explore the association combined nutritional status and activities of daily living disability with all-cause mortality of older adults with hip fracture in the first year after hospitalization.

Methods: This is a single-center retrospective cohort study in older adults with hip fracture patients. Clinical data and laboratory results were collected from electronic medical record system of our hospital (2014-2021). The endpoint of this study was all-cause mortality in the first year after hospitalization.

Results: A total of 303 older adults were enrolled and all-cause mortality was 21.8%. The study population was categorized by CONUT score. Patients in CONUT score 5-12 had a higher age, ASA status, CRP and creatinine level, more patients with history of fracture, pneumonia and delirium, meanwhile, lower BMI and ADL score, lower hemoglobin, lymphocyte, total protein, albumin, triglyceride, total cholesterol and one year survival than those in CONUT score 0-4 (all P < 0.05). Multivariable Cox analysis showed that BMI, ADL score and CONUT score were independent risk factors for all-cause mortality of hip fracture in older adults (HR (95% CI):2.808(1.638, 4.814), P < 0.001; 2.862(1.637, 5.003), P < 0.001; 2.322(1.236, 4.359), P = 0.009, respectively). More importantly, the combined index of CONUT and ADL score had the best predictive performance based on ROC curve (AUC 0.785, 95% CI: 0.734-0.830, P < 0.0001). Kaplan-Meier survival curves for all-cause mortality showed that patients with CONUT score increase and ADL score impairment had a higher mortality rate at 1 year compared to CONUT score decrease and ADL score well (Log Rank χ2 = 45.717, P < 0.0001).

Conclusions: Combined CONUT and ADL score is associated with one-year mortality after hip fracture surgery for geriatric patients.

Background: Low grip strength and gait speed are associated with mortality. However, investigation of the additional mortality risk explained by these measures, over and above other factors, is limited.

Aim: We examined whether grip strength and gait speed improve discriminative capacity for mortality over and above more readily obtainable clinical risk factors.

Methods: Participants from the Health, Aging and Body Composition Study, Osteoporotic Fractures in Men Study, and the Hertfordshire Cohort Study were analysed. Appendicular lean mass (ALM) was ascertained using DXA; muscle strength by grip dynamometry; and usual gait speed over 2.4-6 m. Verified deaths were recorded. Associations between sarcopenia components and mortality were examined using Cox regression with cohort as a random effect; discriminative capacity was assessed using Harrell's Concordance Index (C-index).

Results: Mean (SD) age of participants (n = 8362) was 73.8(5.1) years; 5231(62.6%) died during a median follow-up time of 13.3 years. Grip strength (hazard ratio (95% CI) per SD decrease: 1.14 (1.10,1.19)) and gait speed (1.21 (1.17,1.26)), but not ALM index (1.01 (0.95,1.06)), were associated with mortality in mutually-adjusted models after accounting for age, sex, BMI, smoking status, alcohol consumption, physical activity, ethnicity, education, history of fractures and falls, femoral neck bone mineral density (BMD), self-rated health, cognitive function and number of comorbidities. However, a model containing only age and sex as exposures gave a C-index (95% CI) of 0.65(0.64,0.66), which only increased to 0.67(0.67,0.68) after inclusion of grip strength and gait speed.

Conclusions: Grip strength and gait speed may generate only modest adjunctive risk information for mortality compared with other more readily obtainable risk factors.

Conducted physically, supervised group-based falls prevention exercise programs have demonstrated effectiveness in reducing the risk of falls among older adults. In this study, we aimed to assess the acceptability, feasibility, and effectiveness of a virtual supervised group-based falls prevention exercise program (WE-SURF™) for community-dwelling older adults at risk of falls.

Method: A preliminary study utilizing virtual discussions was conducted to assess the acceptability of the program among six older adults. Effectiveness was evaluated in a randomized controlled feasibility study design, comprising 52 participants (mean age: 66.54; SD: 5.16), divided into experimental (n = 26) and control (n = 26) groups. The experimental group engaged in a 6-month WE-SURF™ program, while the control group received standard care along with a fall's prevention education session. Feasibility of the intervention was measured using attendance records, engagement rates from recorded videos, dropouts, attrition reasons, and adverse events.

Results: Preliminary findings suggested that WE-SURF™ was acceptable, with further refinements. The study revealed significant intervention effects on timed up and go (TUG) (η2p:0.08; p < 0.05), single leg stance (SLS) (η2p:0.10; p < 0.05), and lower limb muscle strength (η2p:0.09; p < 0.05) tests. No adverse events occurred during the program sessions, and both attendance and engagement rates were high (> 80% and 8/10, respectively) with minimal dropouts (4%). The WE-SURF™ program demonstrated effectiveness in reducing the risk of falls while enhancing muscle strength and balance.

Conclusion: In conclusion, WE-SURF™ was demonstrated to be an acceptable, feasible, and effective virtual supervised group-based exercise program for fall prevention in community-dwelling older adults at risk of falls. With positive outcomes and favourable participant engagement, WE-SURF™ holds the potential for wider implementation. Further research and scaling-up efforts are recommended to explore its broader applicability. (Registration number: ACTRN 12621001620819).

Introduction: Femoral fractures in elderly individuals present significant health challenges, often leading to increased morbidity and mortality. Acute kidney injury (AKI) during hospitalization further complicates outcomes, yet the interaction between AKI severity and comorbidities, as quantified by the Charlson Comorbidity Index (CCI), remains poorly understood in this population. This study aimed to assess the associations between AKI severity and the CCI and between AKI severity and one-year mortality postfemoral fracture in elderly patients.

Methodology: This study utilized data from the Multiparameter Intelligent Monitoring in Intensive Care (MIMIC-IV) database and focused on elderly patients (> 65 years) admitted with hip fractures. Patients were categorized based on AKI stage according to the KDIGO criteria and CCI scores. The primary outcome assessed was all-cause mortality one year after hospital discharge. The statistical analyses included logistic regression, Cox proportional hazards regression and moderation analysis with the Johnson-Neyman technique to evaluate associations between AKI and long-term mortality and between the CCI and long-term mortality.

Results: The analysis included 1,955 patients and revealed that severe AKI (stages 2 and 3) was independently associated with increased one-year mortality. Notably, the CCI moderated these associations significantly. A lower CCI score was significantly correlated with greater mortality in patients with severe AKI. The impact of severe AKI was greater for those with a CCI as low as 3, more than doubling the observed one-year mortality rate. In contrast, higher CCI scores (≥8) did not significantly impact mortality. Sensitivity analyses supported these findings, underscoring the robustness of the observed associations.

Conclusion: This study elucidates the complex interplay between AKI severity and comorbidities and long-term mortality in elderly hip fracture patients. These findings underscore the importance of considering both AKI severity and comorbidity burden in prognostic assessments and intervention strategies for this vulnerable population. Targeted interventions tailored to individual risk profiles may help mitigate the impact of AKI on mortality outcomes, ultimately improving patient care and outcomes. Further research is warranted to explore the underlying mechanisms involved and refine risk stratification approaches in this population.

Background: Health services should anticipate the changing pattern of illnesses associated with population aging to promote healthy aging.

Aim: We aimed to evaluate health indices and chronic illnesses and their relationship with functional independence in community Syrian refugees & Jordanian elderly.

Methods: A stratified sample of 1,718 community older adults aged ≥ 60-year-old from four major Jordanian governorates was interviewed in this cross-sectional study. Katz Index of Independence in Activities of Daily Living was utilized to assess functional status. Data were analyzed using STATA 15.

Results: Despite the similarities in baseline function, Syrian refugees had more multimorbidities but less active health insurance, accessibility to healthcare services and availability of medications and medical devices than Jordanians. Two-thirds had multimorbidities; with heart diseases, musculoskeletal conditions, hypertension, and diabetes being the most commonly reported chronic illnesses. Females had significantly more multimorbidities, and functional dependence, yet less education, income and accessibility to healthcare services. The mean Katz Index score was 4.99 ± 1.61. Significant predictors of functional dependence included increasing age, lower level of education, and some chronic illnesses.

Conclusion: National inclusive plans to support vulnerable older adults especially refugees and older women, provide health insurance, enhance access to health care facilities, and manage chronic medical illnesses comprehensively are urgently needed to improve independence of community-living older adults and to promote healthy aging.

Background: The guideline was promoted by the Italian General Practitioners-Primary Care and Geriatrics Hospital-Community Societies and was carried out involving the National Institute of Health and an Expert Panel including representatives from 25 Scientific and Health-Professional Organizations. The aim of the Guideline was to develop evidence-based recommendations on the efficacy of CGA in older people across different clinical settings and the accuracy and utility of CGA-based tools to assess prognosis.

Methods: According to the methodological handbook of the Italian National System of Guidelines and NICE criteria (National Institute for Health and Care Excellence in England), the Guideline was produced based on the Grading of Recommendations Assessment, Development and Evaluation. Over 20,000 records gathered through databases searches were initially selected. Sixteen recommendations on CGA efficacy were defined based on 117 studies that met the inclusion criteria and were performed in general practices and primary care (26 studies included), medical and surgical clinics (16 studies), emergency departments (17 studies), hospital medical and surgical wards (53 studies), long-term care facilities and nursing homes (5 studies), hospices and palliative care networks (no studies). Nine recommendations on CGA-based prognostic tools were issues based on 42 included studies carried out in general practices and primary care (5 studies), medical and surgical clinics (4 studies), and hospital wards (33 studies).

Results: Using CGA can be useful to reduce hospitalization, mortality, institutionalization, the risk of delirium, and improve appropriateness in drug prescription and maintain functional activities in different settings. Further research on the efficacy of CGA in rehabilitative facilities, nursing homes, and hospice and palliative-care settings is recommended. CGA-based tools, particularly the Multidimensional Prognostic Index, should be used to predict some negative outcomes in different settings.

Conclusions: This Guideline may be useful in clinical practice and as a tool to support research on the use of CGA in older people.

Background: The "PromeTheus" trial is evaluating a home-based, multifactorial, interdisciplinary prevention program for community-dwelling (pre-)frail older adults. These individuals often suffer from reduced participation, which can complicate the recruitment and enrollment in a clinical trial.

Aims: The aim of this study was to evaluate different recruitment strategies and differences in participant characteristics in relation to these strategies.

Methods: This cross-sectional study used baseline data from the randomized-controlled PromeTheus trial, in which community-dwelling (pre-)frail older persons (Clinical Frailty Scale [CFS] 4-6 pt., ≥ 70 years) were recruited via general practitioners ("GP recruitment") or flyers, newspaper articles, and personalized letters ("direct recruitment"). Differences in the sociodemographic, clinical, physical, functional, mobility-related, psychological and social characteristics were analyzed in relation to the recruitment strategy.

Results: A total of 385 participants (mean age = 81.2, SD 5.9 years; women: n = 283, 73.5%) were enrolled, of which 60 (16%) were recruited by GPs and 325 (84%) through direct recruitment. Participants recruited via GPs had significantly higher subjective frailty levels (CFS), were more often physically frail (Fried Frailty Phenotype), and showed lower physical capacity (Short Physical Performance Battery), participation (disability component of the short version of the Late-Life Function and Disability Instrument), and life-space mobility (Life-Space Assessment) compared to those recruited via the direct approach (p = 0.002-0.026). Costs per randomized participant were 94€ for the GP recruitment strategy and €213 for the direct recruitment strategy.

Conclusion: Different strategies may be required to successfully recruit (pre-)frail home-living older adults into preventive programs. Direct recruitment strategies, in which potential participants are directly informed about the prevention program, seem to be more promising than GP recruitment but may result in enrolment of persons with less functional impairment and higher recruitment costs.

Background: Pain is linked to disability, but how multisite musculoskeletal pain leads to disability over time is not well elaborated.

Objective: To examine the associations of multisite musculoskeletal pain with disability among a nationally representative cohort.

Design: We used data from the National Health and Aging Trends Study (NHATS) 2015-22. Disability was assessed by basic activities of daily living (ADL) and instrumental activities of daily living (IADL).

Participants: A total of 5557 individuals with multisite musculoskeletal pain dwelling in the community were included in this study.

Methods: Group-based trajectory models were applied to identify distinct profiles of disability in ADL and IADL. Design-based logistic regressions were used to examine associations among multisite musculoskeletal pain, disability, and dual trajectory group memberships, adjusted for sociodemographic, health status, behavioral, and mental characteristics.

Results: Persons who experienced multisite musculoskeletal pain were at higher risk of disability in ADL and IADL. We identified five heterogeneous disability trajectories and named them based on baseline levels and rates of increase over time. Approximately, 52.42% of older adults with multisite musculoskeletal pain were in trajectories with ADL and IADL declines, and 33.60% experienced a rapid decline. Multisite musculoskeletal pain was associated with elevated relative risk for the adverse disability trajectories, which generally increases with multisite musculoskeletal pain frequency and number of sites.

Conclusions: Persons with multisite musculoskeletal pain had a higher risk of disability. It is essential to adopt effective pain management strategies to maintain the independent living ability of older adults and to realize active aging.

Objective: To describe the 10-year preclinical cognitive trajectories of older, non-demented individuals towards the onset of the four most prevalent types of dementia, i.e., Alzheimer's disease(AD), Lewy body(LBD), vascular(VD) and frontotemporal dementia(FTD).

Methods: Our analysis focused on data from older (≥ 60years) NACC (National Alzheimer's Coordinating Center) participants. Four distinct presymptomatic dementia groups (AD-LBD-VD-FTD) and a comparison group of cognitively unimpaired(CU) participants were formed. Comprehensive cognitive assessments involving verbal episodic memory, semantic verbal fluency, confrontation naming, mental processing speed - attention and executive function - cognitive flexibility were conducted at baseline and on an approximately yearly basis. Descriptive analyses (adjusted general linear models) were performed to determine and compare the yearly cognitive scores of each group throughout the follow-up. Exploratory analyses were conducted to estimate the rates of cognitive decline.

Results: There were 3343 participants who developed AD, 247 LBD, 108 FTD, 155 VD and 3398 composed the CU group. Participants with AD performed worse on episodic memory than those with VD and LBD for about 3 to 4 years prior to dementia onset (the FTD group documented an intermediate course). Presymptomatic verbal fluency and confrontation naming trajectories differentiated quite well between the FTD group and the remaining dementia entities. Participants with incident LBD and VD performed worse than those with AD on executive functions and mental processing speed-attention since about 5 years prior to the onset of dementia, and worse than those with FTD more proximally to the diagnosis of the disorder.

Conclusions: Heterogeneous cognitive trajectories characterize the presymptomatic courses of the most prevalent dementia entities.
