Frailty in elderly people

The association between olfactory subdomains and frailty: A prospective case‒control study investigation

BACKGROUND

Amidst the rise of frailty among a globally aging population, olfactory decline has emerged as a harbinger of frailty and mortality in population-level studies. However, the relationships between frailty and the olfactory subdomains of identification (OI), discrimination (OD), and threshold (OT) remain unexplored. This study prospectively examined the association between olfactory subdomains and the physical frailty phenotype (PFP) to investigate olfactory evaluation as a means of frailty screening.

METHODS

A case‒control study of 45 frail and 45 non-frail individuals matched by age and sex. OT, OD, OI (range 0‒16), and composite sum (threshold, discrimination, and identification scores [TDI], range 0‒48) were measured with Sniffin' Sticks. PFP was defined by presence of three or more criteria: physical inactivity, self-reported exhaustion, muscle weakness, slow gait, and unintentional weight loss. Conditional logistic regression evaluated associations between olfactory subdomains and frailty.

RESULTS

Ninety individuals with mean age of 83.1 ± 4.9 years, 60% female (n = 54), and 87.8% white (n = 79) were included. Olfactory scores were significantly lower in the frail group for OI (9.2 vs. 12.1, p < 0.001), OD (8.1 vs. 11.6, p < 0.001), OT (4.4 vs. 8.5, p < 0.001), and TDI (21.7 vs. 32.2, p < 0.001) than in the non-frail group. A single-point decrease in olfactory score was associated with increased odds of frailty in OT (odds ratio [OR]: 2.21, 95% confidence interval: [1.22, 3.98]), OD (OR: 2.19, 95% CI: [1.32, 3.65]), OI (OR: 2.29, 95% CI: [1.19, 4.39]), and TDI (OR: 1.54, 95% CI: [1.14, 2.08]).

CONCLUSION

The robust association between olfactory subdomain scores and frailty suggests that olfaction may be an accessible signifier of frailty. Future studies should investigate this relationship longitudinally to assess predictive relationships.

Cardiac rehabilitation for old-old patients with heart failure and severe functional impairment

BACKGROUND

The effects of cardiac rehabilitation (CR) in old patients with heart failure (HF) and severe functional impairment (SFI) are not well established.

METHODS

We studied 1397 patients with HF and severe functional impairment, defined as a six-minute walking distance (6MWD) <300 m, admitted to inpatient CR. The patients were divided into three groups: Group A (young, ≤65 years), Group B (old-young, 66 to 75 years), and Group C (old-old, >75 years). The primary outcome was an increase in 6MWD to 300 m or more after CR. We used multivariable Cox modeling to determine the association of the primary outcome with three-year mortality after discharge from CR.

RESULTS

At admission to CR, 38.5 % of the patients in group A, 40.0 % in group B, and 46.3 % in group C (p = .029) were unable to walk unassisted. Of these patients, 29.5 %, 32.6 %, and 30.2 % (p = .835), respectively, regained the ability to walk independently. Overall, 370 (26.5 %) patients achieved the primary outcome, 49.1 % in group A, 32.2 % in group B, and 15.7 % in group C (p < .001). The adjusted HR of 3-year mortality for the patients who achieved the primary outcome was 0.53 (95 %CI 0.34-0.83; p = .005) in group A, 0.49 (95 %CI 0.33-0.74; p = .001) in group B, and 0.68 (95 %CI 0.47-0.98; p = .037) in group C.

CONCLUSIONS

Our findings suggest that old-old patients with HF and severe functional impairment may benefit from CR and that functional improvement may predict improved survival.

Current Health Status of Gulf War Deployed and Gulf War Era Veterans Who Use Veterans Affairs Health Care

Background: Although some recent studies have examined the health of female Gulf War (GW) deployed and non-deployed GW era veterans, these all relied on self-report, which can be inaccurate and subject to recall bias. This study investigated the current health of GW deployed and non-deployed GW era female and male veterans using Veterans Health Administration (VHA) electronic health records (EHR). Methods: We performed a cohort study of deployed GW and non-deployed GW era veterans, identified from a list from the Defense Manpower Data Center (DMDC). We used the VA-Frailty Index (VA-FI), calculated with VHA administrative claims and EHR, as a proxy measure of current health. Results: We identified 402,869 veterans (351,496 GW deployed; 51,3373 non-deployed GW era; 38,555 female) in VHA databases. Deployed female veterans had the highest VA-FI (i.e., were frailest) despite being younger than deployed and non-deployed male veterans and non-deployed female veterans. Compared with deployed male veterans, deployed females were more likely to be pre-frail, mildly, and moderately frail. Health differences between deployed and non-deployed female veterans were more prominent among older (60+ years) than younger (<60 years) veterans. Conclusions: Mirroring reports from recent, smaller survey studies of users and non-users of VA health care, findings from this cohort study indicate that deployed female GW veterans who use VA health care are frailer and have more health deficits than non-deployed female GW era and deployed male GW veterans. Because deployed female GW veterans appear to have additional health care needs, this may warrant increased outreach from women's clinics at VA hospitals.

Urologic care of nonagenarians A retrospective chart review

INTRODUCTION

Nonagenarians represent a rapidly growing patient population in Canada and have unique health concerns. With the goal of preparing urologists to manage this complicated patient population in the future, we sought to characterize referral patterns, diagnoses, investigations, treatments, and associated complications in a cohort of nonagenarians. Our second goal was to review anticholinergic burden (ACB) and rates of anticoagulation in this patient population and to assess the risk of hematuria in those who were anticoagulated.

METHODS

This was a single-center, retrospective chart review of a sample of nonagenarians referred to our tertiary care center between 2009 and 2017. Demographic information, referral patterns, investigations, treatment plans, and outcomes were assessed. We assessed medication lists to calculate ACB scores at the time of referral, in addition to rates of anticoagulation use.

RESULTS

Data was collected for 154 nonagenarians. Hematuria was the most common reason for referral (n=43, 27.9%). Urinary retention and lower urinary tract symptoms (LUTS) were seen in 22 and 36 patients, respectively. The majority of patients underwent routine investigations; however, treatment decisions were frequently based on age and frailty. Mild, moderate and severe ACB scores were seen in 76.6%, 9.33%, and 14.0% of patients, respectively. Of those referred for hematuria, 78.1% were on anticoagulation therapy.

CONCLUSIONS

The most common reasons for urologic referral of nonagenarians include hematuria and LUTS. Most nonagenarians are offered routine investigations, and many are offered minor interventions for common benign and malignant urologic diagnoses. When treating nonagenarians, an individualized patient-centered care approach is likely most appropriate.

Frailty Increases Morbidity and Mortality in Patients Undergoing Oncological Liver Resections: A Systematic Review and Meta-analysis

BACKGROUND

Considered to reflect a patients' biological age, frailty is a new syndrome shown to predict surgical outcomes in elderly patients. In view of the increasing age at which patients are proposed oncological liver surgery and the morbidity associated with it, we attempted to perform a systematic review and meta-analysis to compare morbidity and mortality between frail and nonfrail patients after liver resections.

METHODS

The study was registered with PROSPERO. A systematic search of PubMed and EMBASE databases was performed for all comparative studies examining surgical outcomes after liver resections between frail and nonfrail patients.

RESULTS

Ten studies were included based on the selection criteria with a total of 71,102 patients, split into two groups: frail (n = 17,167) and the control group (n = 53,928). There were more elderly patients with a lower preoperative albumin level in the frail group (p = 0.02, p = 0.001). Frail patients showed higher rates of morbidity with more major complications and a higher incidence of postoperative liver failure (p < 0.001). Mortality (p < 0.001) and readmission rate (p = 0.021) also was higher in frail patients.

CONCLUSIONS

Frailty seems to be a solid predictive risk factor of morbidity and mortality after liver surgery and should be considered a selection criterion for liver surgery in at-risk patients.

Not All Frailty Assessments Are Created Equal: Comparability of Electronic Health Data-Based Frailty Assessments in Assessing Older People in Residential Care

Objectives: To evaluate the comparability of frailty assessment tools - the electronic frailty index (eFI), retrospective electronic frailty index (reFI), and clinical frailty scale (CFS) - in older residents of care facilities. Methods: Data from 813 individuals aged 65 or older, with frailty and co-morbidities, collected between 2022 and 2023, were analysed using various statistical methods. Results: The results showed significant differences in frailty classification among the tools: 78.3% were identified as moderately to severely frail by eFI, 59.6% by reFI, and 92.1% by CFS. Statistical tests confirmed significant differences (p < .05) in their assessments, indicating variability in measurement methods. Discussion: This study advances the understanding of frailty assessment within aged-care settings, highlighting the differences in the efficacy of these assessment tools. It underscores the challenges in frailty assessments and emphasizes the need for continuous refinement of assessment methods to address the diverse facets of frailty in aged care.

Real-Life Management of Patients Aged 80 Years Old and Over With Multiple Myeloma: Results of the EMMY Cohort

INTRODUCTION

Multiple myeloma patients aged 80 years and older are a population more prone to comorbidities and frailty. We aim to describe the real-life management and outcomes of this population. EMMY is a descriptive large-scale study.

PATIENTS

Between 2017 and 2021 we included 4383 patients of which 894 (20.3%) were aged ≥ 80 years. Four cohorts of patients aged ≥ 80 years were analysed: line 1 (L1), line 2 (L2), line 3 (L3) or line 4+ (L4+).

RESULTS

The proportion of patients ≥ 80 years old was 20.8% in L1, 21.3% in L2, 20.9% in L3 and 17.8% in L4+. L1 patients received more treatment including a proteasome inhibitor (PI) (42.9%), L2 patients received mainly an immunomodulator (IMID) (65.9%) or an anti-CD38 (31.5%). For L3, IMID was used in 71.4% than an anti-CD38 (33.5%). L4+ patients received a PI (40.6%), IMID (33.2%) or an anti-CD38 (29.1%). Regarding efficacy, the median progression-free survival was 18.4 months in L1, 15.1 months in L2, 10.4 months in L3 and 6.5 months in L4+. The median overall survival was 49 months in L1, 31.3 months in L2, 21.4 months in L3 and 13.6 months in L4+.

CONCLUSION

EMMY cohort confirmed that patients ≥ 80 years of age represent an important proportion of MM patients, in the de novo or relapse setting. This study is an important step in improving our comprehension and management of treatment in elderly patients.

Frailty assessment and outcomes in primary care for patients with diabetes during Ramadan: implications for risk evaluation and care plans

Background

Frailty is a critical concern for older adults, impacting their susceptibility to adverse events and overall quality of life. This study aimed to determine the frailty status of patients 60 years or older in Abu Dhabi Ambulatory Healthcare Services (AHS) and assess its relation to the stress exerted by Ramadan fasting and the occurrence of any adverse outcomes.

Methods

In this prospective observational study, participants were included if the attending physicians used the IDF-DAR risk stratification assessment tool. A tele-interview was conducted to complete the FRAIL score within 6 weeks before Ramadan 1,444 (CE 2022). The outcome was assessed through another tele-interview and an electronic medical record review after Ramadan.

Results

According to the FRAIL assessment tool, among the 204 patients aged 60 years or older included in the study, 109 (53.4%) were classified as either frail or pre-frail. In total, 20 (9.8%) patients were frail, that is, 1 out of 10, and 89 (43.6%) were pre-frail. The remaining 95 (46.6%) patients were robust. Using logistic regression to assess the occurrence of adverse outcomes after Ramadan fasting, a higher frailty score was identified as the third independent risk factor [B = 0.4, OR = 1.5 (1-2.02-1.86), and p = 0.039] for experiencing an adverse event. The identified factors associated with frailty were age, increased albumin-to-creatinine ratio (ACR), chronic kidney diseases (CKDs), and ischemic heart diseases (beta = 0.27, p = 0.003; beta = 0.24, p = 0.004; beta = 0.2, p = 0.039; and beta = 0.18, p = 0.041, respectively). One-third of the frail patients had an event, while the incidence in pre-frail patients was 11.2%, and among the robust patients, the incidence was 6.3%. Physicians' global assessment of frailty did not align well with the structured FRAIL scoring. Only five (25%) out of the 20 patients identified as frail by the FRAIL assessment tool were also judged as frail or having cognitive function impairment by the physicians' global assessment tool.

Conclusion

Frailty is prevalent among elderly patients with diabetes. Disparity exists between subjective and objective frailty assessments, emphasizing the need for standardized evaluation methods. Using the FRAIL tool is recommended for patients aged 60 or older with diabetes in Abu Dhabi.

Association of preoperative frailty with suboptimal weight loss response among patients undergoing metabolic and bariatric surgery

BACKGROUND

Preoperative patient frailty (i.e., aging-related functional decline across multiple physiological systems) has been linked to greater perioperative complications following metabolic bariatric surgery (MBS). This study evaluated whether preoperative patient frailty predicts 1-year suboptimal weight loss response after primary sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).

METHODS

The Bariatric Frailty Score (BFS), an adapted version of the Canadian Study of Health and Aging-Frailty Index based on 10 variables from MBSAQIP, assessed degree of frailty based on number of deficits (i.e., 0-10). Suboptimal response to MBS was defined as < 20% and < 30% percentage total weight loss (%TWL) at 1 year following SG and RYGB, respectively. Multiple linear and logistic regression models evaluated associations of preoperative BFS score with %TWL and %TWL response thresholds, respectively.

RESULTS

Patients (n = 1574; 78.9% female, 28.3% non-white, mean age 45 ± 12 year; 67% SG) had a mean BFS of 1.6 ± 1.3 (range = 0-7). Overall, higher BFS related to lower %TWL after SG and RYGB (ß = - 0.12 and ß = - 0.17, respectively, p = 0.001). Compared to patients with 0-1 deficits (BFS score ≤ 1; n = 785, 49.9%), those with multiple deficits (BFS score ≥ 2; n = 789, 50.1%) had higher odds of suboptimal weight loss response after SG (OR 1.88, 95% CI 1.40-2.52, p < 0.001) and RYGB (OR 2.18, 95% CI 1.43-3.32, p < 0.001).

CONCLUSION

Having multiple preoperative frailty deficits is associated with higher odds of suboptimal weight loss response after MBS. These findings point to the need for increased frailty screening and appropriate adjunctive interventions (i.e., exercise, nutrition, and cognitive), as these interventions may improve frailty status and MBS outcomes.

Association between frailty and activities of daily living disability in older adults residing in a high-altitude Peruvian Andean community: the Aunqui-Andes study

BACKGROUND

The prevalence of frailty and activities of daily living (ADL) disability may be higher in high-altitude Andean regions, due to chronic hypoxia, malnutrition, and physical challenges. and their association is relevant. This study aimed to evaluate the association between frailty and ADL disability among older adults residing in the Totos district in Peru during the year 2022.

METHODS

A cross-sectional study was conducted in Totos district (mean altitude: 3286 m above sea level), located in Ayacucho, Peru, during 2022. A complete census was employed including residents aged 60 and above. The exposure variable was frailty, defined by fulfilling 3 or more criteria of the Fried phenotype. The outcome variable was ADL disability, defined as a score below 95 on the Barthel index. Generalized linear models with a Poisson family, logarithmic link function, and robust variances were employed to estimate crude prevalence ratios and adjusted prevalence ratios (aPRs), along with their corresponding 95% confidence intervals (CIs).

RESULTS

We evaluated 272 older adults with a mean age of 74 years, of whom 59.9% were female, 62.1% were cohabiting or married and 83.1% had not completed primary education. We found that 19.5% were frail, while 51.1% had ADL disability. In the adjusted regression model, we found frailty increased the prevalence of ADL disability (aPR = 1.77; 95%CI: 1.44-2.16; p < 0.001).

CONCLUSION

Frailty was associated with an increased prevalence of ADL disability. These findings could contribute to establishing government intervention plans to manage disability and frailty within the high-risk group comprising older adults living at high altitudes.

The hazard of mortality across different levels of frailty are increased among patients with high Braden scores

PURPOSE

To examine the prognostic accuracy of the Clinical Frailty Scale (CFS) and Braden Scale (BS) separately and combined for 90-day mortality. Furthermore, to examine the effect of frailty on mortality depending on different levels of the Braden score.

METHODS

The study included acutely admitted medical patients ≥ 65 years. We used an optimum cutoff for CSF and BS at ≥ 4 and ≤ 19, respectively. CFS categorized frailty as Non-frail (< 4), Frail (4-5), and Severely frail (> 5). Prognostic accuracy was estimated by the area under the receiver operating characteristic curves (AUROC) with 95% confidence intervals (CI). Cox regression analysis was used to compute the adjusted hazard ratio (aHR) for mortality.

RESULTS

The mean age among 901 patients (54% female) was 79 years. The AUROC for CFS and BS was 0.65 (CI95% 0.60-0.71) and 0.71 (CI95% 0.66-0.76), respectively. aHR for mortality of CFS ≥ 4, BS ≤ 19, and combined were 2.3 (CI95% 1.2-4.2), 1.9 (CI95% 1.3-2.9), and 1.9 (CI95% 1.3-2.8), respectively. For BS > 19, the aHR for mortality was 2.2 (CI95% 1.0-4.8) and 3.5 (CI95% 1.4-8.6) for 'frail' and 'severely frail', respectively. aHR for BS ≤ 19 was 1.1 (CI95% 0.4-3.2) and 1.3 (CI95% 0.5-3.7) for 'frail' and 'severely frail', respectively.

CONCLUSION

Although CFS and BS were associated with 90-day mortality among older acutely admitted medical patients, the prognostic accuracy was poor-to-moderate, and the combination of CFS and BS did not improve the prognostic accuracy. However, the hazard of mortality across different levels of frailty groups were particularly increased among patients with high BS scores.

Exploring frailty in apparently healthy senior dogs: a cross-sectional study

BACKGROUND

As dogs age, they face various health challenges, and preventive care may be overlooked, impacting their quality of life. Frailty, a concept established in human medicine, has recently been applied to dogs using validated tools like the frailty index and frailty phenotype. This study aims to characterize frailty in senior pet dogs and investigate associated factors. To achieve this goal, 88 apparently healthy dogs, as reported by their owners, voluntarily participated in thorough consultations. These consultations included supplementary examinations such as urinary analyses, hematological assessments, and blood biochemistry. Additionally, owners completed questionnaires addressing their dog's overall health, cognitive and locomotor status, as well as their own attachment to the dog and personality traits. Subsequently, each dog was classified as robust or frail based on the presence of multiple criteria out of a set of five. All collected data underwent preliminary screening by a multiple factorial analysis, followed by binomial logistic regression to model frailty.

RESULTS

The final population consisted of 74 dogs, with a frailty prevalence of 41.9% (95% CI: 30.5 - 53.9). In the statistical analysis, older age of the dog, lower owner attachment score, lack of regular deworming, and a disparity in extraversion between owner and dog were identified as contributing factors to frailty.

CONCLUSIONS

This study emphasizes the importance of regular deworming and strong owner-pet attachment in reducing frailty in dogs. It underscores the significance of proactive pet care and highlights the complex relationship between owner-dog personalities and canine frailty. This research advocates for a holistic approach that considers both human and canine traits to promote better health outcomes.

The application of machine learning for identifying frailty in older patients during hospital admission

BACKGROUND

Early identification of frail patients and early interventional treatment can minimize the frailty-related medical burden. This study investigated the use of machine learning (ML) to detect frailty in hospitalized older adults with acute illnesses.

METHODS

We enrolled inpatients of the geriatric medicine ward at Taichung veterans general hospital between 2012 and 2022. We compared four ML models including logistic regression, random forest (RF), extreme gradient boosting, and support vector machine (SVM) for the prediction of frailty. The feature window as well as the prediction window was set as half a year before admission. Furthermore, Shapley additive explanation plots and partial dependence plots were used to identify Fried's frailty phenotype for interpreting the model across various levels including domain, feature, and individual aspects.

RESULTS

We enrolled 3367 patients. Of these, 2843 were frail. We used 21 features to train the prediction model. Of the 4 tested algorithms, SVM yielded the highest AUROC, precision and F1-score (78.05%, 94.53% and 82.10%). Of the 21 features, age, gender, multimorbidity frailty index, triage, hemoglobin, neutrophil ratio, estimated glomerular filtration rate, blood urea nitrogen, and potassium were identified as more impactful due to their absolute values.

CONCLUSIONS

Our results demonstrated that some easily accessed parameters from the hospital clinical data system can be used to predict frailty in older hospitalized patients using supervised ML methods.

Knowledge mapping of frailty and surgery: a bibliometric and visualized analysis

PURPOSE

Frailty is common in surgical patients and is closely associated with postoperative outcomes.

AIMS

This study employed bibliometric methods to summarize and analyze research related to frailty and surgery, comprehensively analyzing the research structure and providing visualized maps.

METHODS

This study analyzed the volume of publications, countries, institutions, authors, journals, references, and keywords related to perioperative frailty in the Web of Science Core Collection from 1978 to 2024. Visual bibliometric analyses were conducted from multiple perspectives, including collaboration networks, citation analysis, and keyword clustering.

RESULTS

From 1978 to 2024, 21,879 authors from 95 countries and regions published 4,119 papers on perioperative frailty in 973 journals worldwide. The United States has the most publications, while Italy has the highest degree of international collaboration. The University of California System has the highest number of publications. The University of Kansas Medical Center is the institution with the highest centrality. The top nine authors in terms of publication volume are all from the USA. Bowers Christian A. is the most prolific author. The Journal of Vascular Surgery is the journal with the most publications. Current research directions include preoperative risk assessment of frailty, the relationship between frailty and postoperative complications, elderly frailty, and the relationship between frailty and sarcopenia. Research hotspots include risk stratification, postoperative delirium, the elderly, and sarcopenia.

CONCLUSION

This study has identified the research hotspots and trends in perioperative frailty. Our findings will enable researchers to understand this field's knowledge structure better and identify future research directions.

Innovative Chair and System Designs to Enhance Resistance Training Outcomes for the Elderly

INTRODUCTION

This study aims to provide a safe, effective, and sustainable resistance training environment for the elderly by modifying chairs and movement systems used during training, particularly under unsupervised conditions.

MATERIALS AND METHODS

The research focused on investigating the effect of modified chair designs on enhancing physical stability during resistance training by involving 19 elderly participants (mean 72.1, SD 4.7). The study measured changes in the body's acceleration during movements to compare the effectiveness of the modified chairs with those commonly used in chair-based exercise (CBE) training in maintaining physical stability. A system was developed based on experimental video data, which leverages MediaPipe to analyze the videos and compute joint angles, identifying whether the actions are executed correctly.

RESULTS AND CONCLUSIONS

Comparisons revealed that modified chairs offered better stability during sitting (p < 0.001) and stand-up (p < 0.001) resistance training. According to the questionnaire survey results, compared to the regular chair without an armrest, the modified chair provided a greater sense of security and a better user experience for the elderly. Video observations indicated that the correct completion rate for most exercises, except stand-up resistance training, was only 59.75%, highlighting the insufficiency of modified chairs alone in ensuring accurate movement execution. Consequently, the introduction of an automatic system to verify proper exercise performance is essential. The model developed in this study for recognizing the correctness of movements achieved an accuracy rate of 97.68%. This study proposes a new chair design that enhances physical stability during resistance training and opens new avenues for utilizing advanced technology to assist the elderly in their training.

Impact of Pre-Stroke Frailty on Outcome Three Years after Acute Stroke: The Nor-COAST Study

INTRODUCTION

We aimed to explore the predictive value of pre-stroke frailty index (FI) on functional dependency and mortality 3 years after stroke.

METHODS

Based on the Rockwood 36-item FI score, we calculated the pre-stroke FI from medical conditions recorded at baseline in the multicenter prospective Nor-COAST study 2015-2017. Participants with a FI score and a modified Rankin scale (mRS) 0-6 3 years post-stroke were included in this study. We used logistic regression analysis with unfavorable mRS (over 2 vs. 0-2) at 3 years, or dead within 3 years, as dependent variable, and frailty and pre-stroke mRS, one at a time, and simultaneously, as predictors. The analyses were carried out unadjusted and adjusted for the following variables one at a time: Age, sex, years of education, stroke severity at admission, infections treated with antibiotics and stroke progression. We report odds ratio (OR) per 0.10 increase in FI.

RESULTS

At baseline, the 609 included patients had mean age 72.8 (standard deviation [SD] 11.8), 261 (43%) were females, and had a FI mean score of 0.16 (SD 0.12), range 0-0.69. During 3 years, 138 (23%) had died. Both the FI, and pre-stroke mRS, were strong predictors for unfavorable mRS (OR 4.1 and 2.7) and dead within 3 years (OR 2.2 and 1.7). Only adjusting for age affected the result. The OR for pre-stroke mRS decreased relatively more than the OR for FI when entered as predictors simultaneously.

CONCLUSIONS

FI is a stronger predictor than premorbid mRS for prognostication after stroke.

Transition of Physical, Psychological, and Cognitive Frailty and Its' Associated Determinants in Malaysian Older Adults: A 5-Year Follow-up Study

Frailty, a multifaceted syndrome, affects approximately 26% of older adults globally, yet there are limited data on the prevalence and longitudinal impact of frailty subtypes. Therefore, in this study, we aim to determine the prevalence of physical, psychological, and cognitive frailty, transitions between subtypes, and associated health determinants among Malaysian community-dwelling older adults. This study is part of the longitudinal aging study in Malaysia (LRGS Ageless and TUA). We assessed 815 older adults in 2014, with successful follow-up of 402 participants (mean age: 67.08 ± 5.38 years) after 5 years. Frailty subtypes were assessed at baseline, and transitions were evaluated at the 5-year mark. At baseline, the prevalence of older adults categorized as robust, physical frailty, cognitive frailty, and psychological frailty was 26.7%, 36.3%, 12.1%, and 16.7%, respectively, with 8.1% exhibiting concurrent psychological and cognitive frailty. Follow-up results showed that 22.9% remained robust, 46.8% experienced no change, 24.9% deteriorated (adversed), and 5.5% improved (reversed). Logistic regression analysis identified living alone (p < 0.001), increased body fat percentage (p < 0.05), increased waist circumference (p < 0.05), reduced fat-free mass (p < 0.05), decreased lower limb flexibility (p < 0.05), and declined cardiorespiratory fitness (p < 0.05) as significant predictors of frailty deterioration. Higher Mini Mental State Examination (MMSE) scores and improved Timed Up and Go and Chair Stand test results (p < 0.05) were significantly associated with the reversal of frailty subtypes (p < 0.05). Younger older adults (p < 0.001), males (p < 0.05), those with lower WHO Disability Scale scores (p < 0.05), and higher MMSE scores (p < 0.05) were significantly less likely to develop frailty subtypes. Intervention strategies that focus on combined physical, cognitive, and psychosocial functions are crucial for both reversing and preventing the progression of frailty subtypes in older adults.

Predictors of Morbidity, Mortality, and Hospital Utilization Among Endoscopic Retrograde Cholangiopancreatography-related Hospitalizations: A Five-year Nationwide Assessment

OBJECTIVE

We aimed to assess the hospital frailty risk score on the inpatient mortality, morbidity, and health care resource utilization among endoscopic retrograde cholangiopancreatography (ERCP)-related hospitalizations.

BACKGROUND

Data regarding the inpatient mortality, morbidity, and health care resource utilization of ERCP among frail individuals remain limited.

MATERIALS AND METHODS

Using the Nationwide Inpatient Sample, we compared the odds of inpatient mortality and morbidity of ERCP-related hospitalizations among individuals with low frailty scores, intermediate frailty scores (IFSs), and high frailty scores (HFSs).

RESULTS

Overall, 776,025 ERCP-related hospitalizations were recorded from 2016 to 2020. 552,045 had a low frailty score, whereas 217,875 had an IFS, and 6105 had an HFS. Frail individuals had a 5-fold increase in mortality [IFS: adjusted odds ratio (aOR) = 4.81, 95% CI: 3.77-6.14; HFS: aOR = 4.62, 95% CI: 2.48-8.63]. An IFS was associated with a 24% increase in post-ERCP pancreatitis (aOR = 1.25, 95% CI: 1.11-1.41), a 3-fold increase in post-ERCP bleeding (aOR = 2.59, 95% CI: 1.82-3.67), and a 2-fold increase in post-ERCP duct perforation (aOR = 1.91, 95% CI: 1.38-2.64). Frail individuals experienced higher odds of in-hospital morbidity, including secondary sepsis, respiratory failure, acute kidney injury, cerebrovascular accidents, deep vein thrombosis, and pulmonary embolism.

CONCLUSIONS

In summary, our study presents strong evidence in support of using the hospital frailty risk score as an index to predict mortality and morbidity during ERCP-related hospitalizations. Additional caution is warranted in the management of frail individuals undergoing ERCP.

Defining an ageing-related pathology, disease or syndrome: International Consensus Statement

Around the world, individuals are living longer, but an increased average lifespan does not always equate to an increased health span. With advancing age, the increased prevalence of ageing-related diseases can have a significant impact on health status, functional capacity and quality of life. It is therefore vital to develop comprehensive classification and staging systems for ageing-related pathologies, diseases and syndromes. This will allow societies to better identify, quantify, understand and meet the healthcare, workforce, well-being and socioeconomic needs of ageing populations, whilst supporting the development and utilisation of interventions to prevent or to slow, halt or reverse the progression of ageing-related pathologies. The foundation for developing such classification and staging systems is to define the scope of what constitutes an ageing-related pathology, disease or syndrome. To this end, a consensus meeting was hosted by the International Consortium to Classify Ageing-Related Pathologies (ICCARP), on February 19, 2024, in Cardiff, UK, and was attended by 150 recognised experts. Discussions and voting were centred on provisional criteria that had been distributed prior to the meeting. The participants debated and voted on these. Each criterion required a consensus agreement of ≥ 70% for approval. The accepted criteria for an ageing-related pathology, disease or syndrome were (1) develops and/or progresses with increasing chronological age; (2) should be associated with, or contribute to, functional decline or an increased susceptibility to functional decline and (3) evidenced by studies in humans. Criteria for an ageing-related pathology, disease or syndrome have been agreed by an international consortium of subject experts. These criteria will now be used by the ICCARP for the classification and ultimately staging of ageing-related pathologies, diseases and syndromes.

Association of Gut Microbiome with Muscle Mass, Muscle Strength, and Muscle Performance in Older Adults: A Systematic Review

Sarcopenia, characterized by reduced muscle mass, strength, or performance, is a common condition in older adults. The association between the gut microbiome and sarcopenia remains poorly understood. This systematic review aims to evaluate the relationship between muscle parameters and the intestinal microbiome. A systematic search was conducted in PubMed, EMBASE, Cochrane Library, and Google Scholar for studies published between 2002 and 2022 involving participants aged 50+. Studies were included if they assessed sarcopenia using at least one measure of muscle mass (skeletal muscle mass, bioelectrical impedance analysis, MRI), muscle strength, or muscle performance (SARC-F questionnaire, Timed-Up-and-Go Test, Chair Stand Test, grip strength, gait speed, Short Physical Performance Battery, 400 m Walk Test). The microbiome was measured using at least RNA/DNA sequencing or shotgun metagenomic sequencing. Twelve studies were analyzed. Findings revealed that a higher abundance of bacterial species such as Desulfovibrio piger, and Clostridium symbiosum and reduced diversity of butyrate-producing bacteria was associated with sarcopenia severity, as indicated by decreased grip strength, muscle mass, or physical performance. The gut microbiome plays a significant role in age-related muscle loss. Probiotics, prebiotics, and bacterial products could be potential interventions to improve muscle health in older adults.

Frailty and Long-Term Mortality Following Emergency Laparotomy: A Comparison Between the 11-Item and 5-Item Modified Frailty Indices

INTRODUCTION

Emergency laparotomy (EL) is a high-risk operation which is increasingly performed on an aging patient population. Objective frailty assessment using a validated index has the potential to improve preoperative risk stratification. This study aimed to assess the correlation between frailty and long-term mortality and morbidity outcomes for older EL patients. Secondary aims were to compare the 11-item and shortened five-item modified frailty indices (mFIs) in terms of value and predictive validity.

METHODS

A prospective multicenter observational study of patients aged ≥55 y undergoing EL was conducted across five hospitals in New Zealand between 2017 and 2022. Frailty was measured using the 11-item and abbreviated five-item mFIs. Multivariable logistic regression was used to determine whether frailty was independently associated with one-year postoperative mortality and other morbidity outcomes. Correlation between the two frailty indices were assessed with the Spearman's correlation coefficient (P).

RESULTS

Frailty assessments were performed in 861 participants, with the prevalence being 18.7% and 29.8% using the 11-item and five-item mFIs, respectively. Both frailty indices demonstrated similar associations with one-year mortality (two-fold increased risk), major complications, admission to intensive care unit, rehabilitation, and 30-d readmission. The 11-item mFI demonstrated a greater association with early mortality (four-fold increased risk), reoperations, and increased length of stay compared with the five-item frailty index. Spearman P was 0.6 (P < 0.001).

CONCLUSIONS

Frailty, as identified by the 11-item and five-item mFIs, was associated with one-year mortality and other important morbidity outcomes for older EL patients. These forms of frailty assessment provide important information that may aid in risk assessment and patient-centered decision-making.

Comprehensive Geriatric Assessment, Treatment Decisions, and Outcomes in Older Patients Eligible for Pancreatic Surgery

INTRODUCTION

Periampullary cancer has a poor prognosis. Surgical resection is a potentially curative but high-risk treatment. Comprehensive geriatric assessment (CGA) can inform treatment decisions, but has not yet been evaluated in older patients eligible for pancreatic surgery.

METHODS

This prospective observational study included patients ≥ 70 years of age eligible for pancreatic surgery. Frailty was defined as impairment in at least two of five domains: somatic, psychological, functional, nutritional, and social. Outcomes included postoperative complications, functional decline, and mortality.

RESULTS

Of the 88 patients included, 87 had a complete CGA. Sixty-five patients (75%) were frail and 22 (25%) were non-frail. Frail patients were more likely to receive nonsurgical treatment (43.1% vs. 9.1% p = 0.004). Fifty-seven patients underwent surgery, of which 52 (59%) underwent pancreaticoduodenectomy. The incidence of postoperative delirium was three times higher in frail patients (29.7% vs. 0%, p = 0.005). The risk of mortality was three times higher in frail patients (HR: 3.36, 95% CI: 1.43-7.89, p = 0.006).

CONCLUSION

Frailty is common in older patients eligible for pancreatic surgery and is associated with treatment decision, a higher incidence of delirium and a three times higher risk of all-cause mortality. CGA can contribute to shared decision-making and optimize perioperative care in older patients.

Prevalence and potential influencing factors for social frailty among community-dwelling older adults: a systematic review and meta-analysis

OBJECTIVE

To explore the prevalence and potential influencing factors of social frailty among community-dwelling older adults from a global perspective.

METHODS

Systematic searches were conducted on multiple databases including CNKI, VIP, Wanfang Data, CBM, Pubmed, Cochrane Library, Web of Science, and Embase from inception to January 9, 2024. Two researchers performed a thorough literature search, gathered data, and independently evaluated the quality of the articles.

RESULTS

2,426 literatures were examined, 45 were found to meet the specified criteria for inclusion, encompassing 314,454 participants. The combined prevalence of social pre-frailty and social frailty among community-dwelling older adults were found to be 34.5% and 21.1%, respectively. Depression, activities of daily living (ADL), physical inactivity, motor deficits, cognitive impairment, and physical frailty are potential risk factors.

CONCLUSIONS

Social pre-frailty and social frailty are frequent challenges faced by older adults living in the community. The prevalence of these conditions has been on the rise in recent years, underscoring the importance of implementing effective interventions. Early identification and intervention for individuals at risk of social frailty are essential for promoting healthy and active aging globally.

The mediating and moderating effect of health-promoting lifestyle on frailty and depressive symptoms for Chinese community-dwelling older adults: A cross-sectional study

BACKGROUND

This study aims to explore the mediating and moderating effect of health-promoting lifestyles on the relationship between frailty and depressive symptoms to provide a practical reference for effectively promoting the mental health of older adults.

METHODS

A cross-sectional survey of community-dwelling older adults (n = 3107) was conducted in three cities of Ningxia Province, China. Depressive symptoms, frailty, and health-promoting lifestyles were assessed through the 30-item Geriatric Depression Scale, frailty scale, and health-promoting Lifestyle profile-II, respectively. The Bootstrap methods PROCESS program is employed to test the mediation and moderation model.

RESULTS

The findings indicated that health-promoting lifestyles are negatively related to depressive symptoms and frailty, while frailty is positively associated with depressive symptoms. Health-promoting lifestyles have mediated the relationship between frailty and depressive symptoms. Besides, the health-promoting lifestyles weakened the positive relationship between frailty and depression symptoms; there existed a moderating effect of health-promoting lifestyles on the relationship between frailty and depression symptoms among older adults.

LIMITATIONS

Given the cross-sectional study, it is impossible to make causal inferences.

CONCLUSIONS

A health-promoting lifestyle might be a protective factor for older adults' health in China. The mediating and moderating effect of a health-promoting lifestyle on the relationship between frailty and depression symptoms among older adults should be integrated to achieve maximum utility. Healthcare practitioners and medical service personnel are recommended to advance health education and publicity, encouraging healthy lifestyles among community-dwelling older adults with frailty to prevent depressive symptoms and promote healthy aging.

Common Characteristics Between Frailty and Myotonic Dystrophy Type 1: A Narrative Review

Myotonic dystrophy type 1 (DM1) is an inherited neuromuscular disorder often considered a model of accelerated aging due to the early appearance of certain age-related clinical manifestations and cellular and molecular aging markers. Frailty, a state of vulnerability related to aging, has been recently studied in neurological conditions but has received considerably less attention in neuromuscular disorders. This narrative review aims to describe 1) the common characteristics between Fried's frailty phenotype criteria (muscular weakness, slow gait speed, weight loss, exhaustion/fatigue, and low physical activity) and DM1, and 2) the psychological and social factors potentially contributing to frailty in DM1. This review gathered evidence suggesting that DM1 patients meet four of the five frailty phenotype criteria. Additionally, longitudinal studies report the deterioration of these criteria over time in DM1. Patients also exhibit psychological/cognitive and social factors that might contribute to frailty. Monitoring frailty criteria in the DM1 population could help to implement timely preventions and interventions to reduce the disease burden and severity of frailty symptoms.

Association between changes of frailty status/frailty components status and rapid loss of kidney function in middle- aged and older populations

BACKGROUND

Frailty and its components are proposed to associate with kidney function, but little attention is paid to the significance of changes in their status on rapid loss of kidney function. This study aimed to investigate the association between changes in frailty and its components status with rapid loss of renal function.

METHODS

This study used data from China Health and Retirement Longitudinal Study (CHARLS). Frailty status was measured using the Fried frailty phenotype (FP) scale, including five components: slowness, weakness, exhaustion, inactivity, and shrinking. Frailty status was further classified into three levels: robust (0 component), prefrail (1-2 components) and frail (3-5 components). Changes in frailty status were assessed by frailty status at baseline and 4- year follow-up. Rapid loss of kidney function was defined as a rate of estimate glomerular filtration rate(eGFR) decline ≥ 4 ml/min per 1.73 m2per year. Logistic regression models were performed to assess the association between changes in frailty status and its components status with rapid eGFR decline.

RESULTS

A total of 2705 participants were included with 316 (11.68%) participants categorized as rapid eGFR decline during the 4-year follow-up. Compared with baseline prefrail participants who progressed to frail, prefrail participants who maintained prefrail or recovered to robust status had decreased risks of rapid eGFR decline (stable prefrail status, OR = 0.608, 95% CI: 0.396-0.953; recover to robust, OR = 0.476, 95% CI: 0.266-0.846). In contrast, among baseline robust or frail participants, we did not find changes in frailty status significantly affect the risks of rapid loss of kidney function. Moreover, participants who experienced incident weakness showed the significant relationship with an increased risk of rapid eGFR decline (OR = 1.531, 95% CI: 1.051-2.198) compared to stable non-weakness participants. Other changes of frailty components status did not significantly affect the risks of rapid eGFR decline.

CONCLUSIONS

The progression of frailty status increases the risks of rapid eGFR decline among prefrail populations. Preventing weakness, may benefit kidney function.

VO2MAX, 6-minute walk, and muscle strength each correlate with frailty in US veterans

Introduction

Frailty often manifests as an increased vulnerability to adverse outcomes, and detecting frailty is useful for informed healthcare decisions. Veterans are at higher risk for developing frailty and at younger ages. The goal of this study was to investigate approaches in Veterans that can better inform the physiologic underpinnings of frailty, including maximal oxygen uptake (VO2max), 6-min walk, muscle strength, and inflammatory biomarkers.

Methods

Participants (N = 42) were recruited from the Buffalo VA Medical Center. Inclusion criteria: ages 60-85, male or female, any race, and not having significant comorbidities or cognitive impairment. Outcome measures included: the Fried frailty phenotype, the short physical performance battery (SPPB), quality of life (QOL) using the Q-LES-Q-SF, and the following physiologic assessments: VO2max assessment on an upright stationary bicycle, 6-min walk, and arm and leg strength. Additionally, inflammatory biomarkers (C-reactive protein, IL-6, IL-10, interferon-γ, and TNF-α) were measured using ELLA single and multiplex ELISA.

Results

Participants: 70.3 ± 7.4 years of age: 34 males and 8 females, BMI = 30.7 ± 5.4 kg/m2, 26 white and 16 African American. A total of 18 (42.8%) were non-frail, 20 (47.6%) were pre-frail, and 4 (9.5%) were frail. VO2max negatively correlated with Fried frailty scores (r = -0.40, p = 0.03, N = 30), and positively correlated with SPPB scores (r = 0.50, p = 0.005), and QOL (r = 0.40, p = 0.03). The 6-min walk test also significantly correlated with VO2max (r = 0.57, p = 0.001, N = 42) and SPPB (r = 0.55, p = 0.0006), but did not quite reach a significant association with frailty (r = -0.28, p = 0.07). Arm strength negatively correlated with frailty (r = -0.47, p = 0.02, N = 26), but not other parameters. Inflammatory profiles did not differ between non-frail and pre-frail/frail participants.

Conclusion

Objectively measured cardiorespiratory fitness was associated with important functional outcomes including physical performance, QOL, and frailty in this group of older Veterans. Furthermore, the 6-min walk test correlated with VO2max and SPPB, but more validation is necessary to confirm sensitivity for frailty. Arm strength may also be an important indicator of frailty, however the relationship to other indicators of physical performance is unclear.

Frailty and Loneliness in Older Adults: A Narrative Review

(1) Background: In a society with an advancing aging rate, medical systems are coming under pressure due to an increasing flow of older patients with multiple somatic diseases, exacerbated by their psychological and sociological backgrounds. We aimed to investigate the relationship between frailty and loneliness in older adults and to provide a holistic perspective on these concepts. Our research question was "Is there a link between the loneliness and frailty in older people?" (2) Methods: To assess the link between loneliness and frailty, we conducted a search accessing Index Medicus and PubMed; the timeframe of our research was from 2013 until 2023. Data regarding the study population, as well as loneliness and frailty assessments and approaches, were extracted. (3) Results: A positive relationship between loneliness and the appearance and progression of frailty in older adults is argued for. (4) Conclusions: Frailty and loneliness in older adults are often interconnected and can have a significant impact on their overall well-being. Early identification of frailty by assessing risk factors (including loneliness and/or social isolation) should become a standard of care for older patients. Appropriate combined interventions that effectively address both frailty and loneliness (physical exercises, psychological support, and social engagement) can promote healthier aging, prevent health deterioration, maintain independence, and reduce healthcare costs.

Association between healthy lifestyle and frailty in adults and mediating role of weight-adjusted waist index: results from NHANES

BACKGROUND

The relationship between healthy lifestyle and frailty remains unclear. Healthy weight is crucial for overall well-being, but using body mass index (BMI) to evaluate weight management is inefficient. This study clarifies the association between healthy lifestyle or its factors (non-smoking, moderate drinking, healthy weight, healthy diet, sufficeint physical activity, and non-sedentary) and frailty, and the feasibility of using the weight-adjusted waist index (WWI) reflecting central obesity as an intermediate indicator.

METHODS

This study included 4,473 participants from the 2007-2018 National Health and Nutrition Examination Survey (NHANES). Healthy lifestyle quality was assessed by summing the scores of each healthy lifestyle factor. Frailty was assessed using a 49-item frailty index (FI), categorizing participants into robust, pre-frail, and frail. Logistic regression to investigate the association between healthy lifestyle or its factors, WWI, and frailty. Smooth curve fitting and threshold effect analyses were used to elucidate the nonlinear association. Subgroup and two other sensitivity analyses were conducted to confirm the stability of the results. A causal mediation model examined the proportion of frailty mediated by WWI.

RESULTS

The study identified 13.98% of the participants as frail. Optimal healthy lifestyle and frailty were negatively associated (OR: 0.39, 95%CI: 0.27-0.58). Five healthy lifestyle factors (non-smoking, healthy weight, healthy diet, sufficient physical activity, and non-sedentary) were associated with a lower prevalence of frailty, with odds ratios (OR) ranging from 0.48 to 0.61. We also analyzed the association between a healthy lifestyle and WWI (OR: 0.32, 95%CI: 0.27-0.37), WWI and frailty (OR: 1.85, 95%CI: 1.59-2.16). A positive association between WWI and FI was observed beyond the inflection point (9.99) (OR: 0.03, 95%CI: 0.02-0.03). Subgroup and sensitivity analyses confirmed stable associations between healthy lifestyle, WWI, and frailty. WWI partially mediated the association between a healthy lifestyle and frailty (mediating ratio = 20.50-20.65%).

CONCLUSIONS

An optimal healthy lifestyle and positive healthy lifestyle factors are associated with a lower incidence of frailty. WWI may mediate the relationship between a healthy lifestyle and frailty.

Frailty as a sequela of burn injury: a post hoc analysis of the "RE-ENERGIZE" multicenter randomized-controlled trial and the National Health Interview Survey

BACKGROUND

With advancements in burn treatment and intensive care leading to decreased mortality rates, a growing cohort of burn survivors is emerging. These individuals may be susceptible to frailty, characterized by reduced physiological reserve and increased vulnerability to stressors commonly associated with aging, which significantly complicates their recovery process. To date, no study has investigated burns as a potential risk factor for frailty. This study aimed to determine the short-term prevalence of frailty among burn survivors' months after injury and compare it with that of the general population.

METHODS

A post hoc analysis was conducted on the Randomized Trial of Enteral Glutamine to Minimize the Effects of Burn Injury (RE-ENERGIZE) trial, an international randomized-controlled trial involving 1200 burn injury patients with partial- or full-thickness burns. Participants who did not complete the 36-Item Short Form Health Survey (SF-36) questionnaire were excluded. Data for the general population were obtained from the 2022 National Health Interview Survey (NHIS). Frailty was assessed using the FRAIL (Fatigue, Resistance, Ambulation, Illness, Loss of weight) scale. Due to lack of data on loss of weight, for the purposes of this study, malnutrition was used as the fifth variable. Illness and malnutrition were based on admission data, while fatigue, resistance, and ambulation were determined from post-discharge responses to the SF-36. The burn cohort and general population groups were matched using propensity score matching and compared in terms of frailty status. Within the burn group, patients were divided into different subgroups based on their frailty status, and the differences in their (instrumental) activities of daily living (iADL and ADL) were compared. A multivariable analysis was performed within the burn cohort to identify factors predisposing to frailty as well as compromised iADL and ADL.

RESULTS

Out of the 1200 burn patients involved in the study, 600 completed the required questionnaires [follow-up time: (5.5 ± 2.3) months] and were matched to 1200 adults from the general population in the U.S. In comparison to the general population, burn patients exhibited a significantly higher likelihood of being pre-frail (42.3% vs. 19.8%, P < 0.0001), or frail (13.0% vs. 1.0%, P < 0.0001). When focusing on specific components, burn patients were more prone to experiencing fatigue (25.8% vs. 13.5%, P < 0.0001), limited resistance (34.0% vs. 2.7%, P < 0.0001), and restricted ambulation (41.8% vs. 3.8%, P < 0.0001). Conversely, the incidence rate of illness was observed to be higher in the general population (1.2% vs. 2.8%, P = 0.03), while no significant difference was detected regarding malnutrition (2.3% vs. 2.6%, P = 0.75). Furthermore, in comparison with robust burn patients, it was significantly more likely for pre-frail and frail patients to disclose compromise in ADL and iADL. The frail cohort reported the most pronounced limitation.

CONCLUSIONS

Our findings suggest a higher incidence of post-discharge frailty among burn survivors in the short-term following injury. Burn survivors experience compromised fatigue, resistance, and ambulation, while rates of illness and malnutrition were lower or unchanged, respectively. These results underscore the critical need for early identification of frailty after a burn injury, with timely and comprehensive involvement of a multidisciplinary team including burn and pain specialists, community physicians, physiotherapists, nutritionists, and social workers. This collaborative effort can ensure holistic care to address and mitigate frailty in this patient population.

Determinants of received care time among Finnish home care clients and assisted living facility residents: a time-motion study

BACKGROUND

Ageing populations and care workforce shortages across Europe are causing challenges for care services for older people. Therefore, it is paramount that limited care resources are allocated optimally, based on the clients' care needs. Multiple functioning-related factors have been identified that determine the amount of care time clients receive, while organizational and other factors remain largely unexplored. The aim was to examine how various individual and organizational factors are associated with clients' received care time in different care settings.

METHODS

Cross-sectional observational study design with data from time and motion study, registers, and surveys was used. In total, 1477 home care clients and 1538 residents from assisted living facilities with 24/7 service participated, from 61 Finnish care units. Linear mixed-effect modeling was used to examine the association between individual and organizational-level variables and received care time.

RESULTS

Physical functioning was the strongest predictor of received care time in both care settings. In home care, greater pain, more unstable health, and higher team autonomy were associated with increased care time. In assisted living, depressive mood and higher staffing level of the organization were associated with care time. Clients who received informal care also received significantly more care time from nurses in both care settings.

CONCLUSIONS

Physical functioning was the main driver of received care time. Interventions that maintain or improve physical functioning can help restrain the growing need of care resources, although it is important to ensure that each client receives care according to their holistic care needs.

Creatinine-to-cystatin C ratio and frailty in older adults: a longitudinal cohort study

BACKGROUND

Creatinine-to-cystatin C ratio (CCR) has been associated with multiple adverse outcomes. However, little is known about its relationship with frailty. We aimed to explore the association between CCR and frailty among older adults.

METHODS

A total of 2599 participants aged ≥ 60 years (mean age 67.9 ± 6.0 years, 50.4% males) were included from the China Health and Retirement Longitudinal Study (2011-2015). Baseline CCR was calculated as plasma creatinine (mg/dL) / cystatin C (mg/L) × 10 and was grouped by quartiles. Frailty was evaluated by the validated physical frailty phenotype (PFP) scale and was defined as PFP score ≥ 3. The generalized estimating equations model was used to explore the relationship between CCR and frailty.

RESULTS

The frailty risk decreased gradually with increasing CCR in the quartiles (P for trend = 0.002), and the fourth CCR quartile was associated with a significantly lower risk of frailty compared with the lowest quartile (odds ratio [OR] 0.37, 95% confidence interval [CI] 0.19-0.70). When modeling as a continuous variable, per 1-unit increase in CCR was related to 17% decreased odds of frailty (OR 0.83, 95% CI 0.74-0.93). The association was consistent in male and female participants (P for interaction = 0.41). Poisson models revealed that frailty score was negatively associated with CCR (β= -0.11, 95% CI= -0.19 to -0.04), and sex did not significantly moderate the associations (P for interaction = 0.22). The results were not affected by further adjusting for high-sensitivity C-reactive protein. Similar results were observed by analyses with multiple imputation technique and analyses excluding participants with baseline frailty.

CONCLUSIONS

Higher CCR was associated with a lower frailty risk. CCR may be a simple marker for predicting frailty in older adults.

Causal associations between frailty and low back pain: a bidirectional two-sample mendelian randomization study

BACKGROUND

Previous observational studies have revealed a potentially robust bidirectional relationship between frailty and low back pain (LBP). However, the precise causal relationship remains unclear.

METHODS

To examine the potential causal association between frailty and LBP, we conducted bidirectional two-sample Mendelian randomization analysis (MR) study. Genetic data on frailty index (FI) and LBP were acquired from publicly available genome-wide association studies (GWAS). Various MR methodologies were utilized, such as inverse variance weighting (IVW), weighted median, and MR-Egger, to evaluate causality. Additionally, sensitivity analyses were conducted to evaluate the robustness of the findings.

RESULTS

Genetically predicted higher FI (IVW, odds ratio [OR] = 1.66, 95% CI 1.17-2.36, p = 4.92E-03) was associated with a higher risk of LBP. As for the reverse direction, genetic liability to LBP showed consistent associations with a higher FI (IVW, OR = 1.13, 95% CI 1.07-1.19, p = 2.67E-05). The outcomes from various MR techniques and sensitivity analyses indicate the robustness of our findings.

CONCLUSION

Our research findings provide additional evidence bolstering the bidirectional causal relationship between frailty and LBP.

Has multimorbidity and frailty in adult hospital admissions changed over the last 15 years? A retrospective study of 107 million admissions in England

BACKGROUND

Few studies have quantified multimorbidity and frailty trends within hospital settings, with even fewer reporting how much is attributable to the ageing population and individual patient factors. Studies to date have tended to focus on people over 65, rarely capturing older people or stratifying findings by planned and unplanned activity. As the UK's national health service (NHS) backlog worsens, and debates about productivity dominate, it is essential to understand these hospital trends so health services can meet them.

METHODS

Hospital Episode Statistics inpatient admission records were extracted for adults between 2006 and 2021. Multimorbidity and frailty was measured using Elixhauser Comorbidity Index and Soong Frailty Scores. Yearly proportions of people with Elixhauser conditions (0, 1, 2, 3 +) or frailty syndromes (0, 1, 2 +) were reported, and the prevalence between 2006 and 2021 compared. Logistic regression models measured how much patient factors impacted the likelihood of having three or more Elixhauser conditions or two or more frailty syndromes. Results were stratified by age groups (18-44, 45-64 and 65 +) and admission type (emergency or elective).

RESULTS

The study included 107 million adult inpatient hospital episodes. Overall, the proportion of admissions with one or more Elixhauser conditions rose for acute and elective admissions, with the trend becoming more prominent as age increased. This was most striking among acute admissions for people aged 65 and over, who saw a 35.2% absolute increase in the proportion of admissions who had three or more Elixhauser conditions. This means there were 915,221 extra hospital episodes in the last 12 months of the study, by people who had at least three Elixhauser conditions compared with 15 years ago. The findings were similar for people who had one or more frailty syndromes. Overall, year, age and socioeconomic deprivation were found to be strongly and positively associated with having three or more Elixhauser conditions or two or more frailty syndromes, with socioeconomic deprivation showing a strong dose-response relationship.

CONCLUSIONS

Overall, the proportion of hospital admissions with multiple conditions or frailty syndromes has risen over the last 15 years. This matches smaller-scale and anecdotal reports from hospitals and can inform how hospitals are reimbursed.

Association between Frailty and Asthma

Background and Objectives: This study investigated whether there is an association between elderly frailty and asthma. Material Methods: We examined 9745 elderly participants who did not have asthma and 275 elderly patients who had asthma diagnosed by a doctor from the 2020 Survey of Living Conditions and Welfare Needs of Korean Older Persons Survey. Study Selections: The Korean version of the fatigue, resistance, ambulation, illnesses, and loss of weight (K-FRAIL) scale was used to determine their level of frailty. The relationship between frailty and geriatric asthma was examined using multiple logistic regression analysis, which was adjusted for a number of confounding variables (socioeconomic, health behavior, psychological characteristics, and functional status). Results: Frailty as defined by the K-FRAIL scale was significantly higher in the asthma group (7.6%) than the non-asthma group (4.9%). The frailty phenotype component showed that resistance, ambulation, and illness severity were more severe in the asthma group than the non-asthma group. After adjusting, asthma was significantly associated with an increased risk of frailty (OR 1.45; 95% confidence interval [CI] 1.01-2.09) compared to the non-asthma group. Conclusions: Frailty might be associated with elderly asthma in patients from the Korean population. Frailty may not only be associated with asthma, but also with other diseases. So, more evidence is needed to establish this association.

Clinical outcomes after idecabtagene vicleucel in older patients with multiple myeloma: a multicenter real-world experience

ABSTRACT

The safety and efficacy of chimeric antigen receptor T-cell therapy is not well described in older patients, a population that has higher frailty and comorbidities. In this multicenter retrospective study, we evaluated clinical outcomes along with frailty and geriatric characteristics such as comorbidities, polypharmacy, falls, neuropathy, organ dysfunction, and performance status in younger (aged <65 years) vs older (aged ≥65 years) patients who received commercial idecabtagene vicleucel (ide-cel). A total of 156 patients (n = 75, aged ≥65 years) were infused with ide-cel by data cutoff. In older patients (median age: 69 years; range, 65-83; 66.7% frail; 77.3% did not meet KarMMa eligibility criteria), with a median follow-up duration of 14.2 months, best overall response rate (ORR) was 86.7%, which was comparable with pivotal KarMMa study results (ORR: 73%). Median progression-free survival and overall survival in older patients were 9.1 months and 26.5 months, respectively. Grade ≥3 cytokine-release syndrome and immune effector cell-associated neurotoxicity syndrome were observed in 1% and 4% of older patients, respectively. Compared with younger patients, the older patients had significantly higher prevalence of frailty, geriatric characteristics such as polypharmacy (≥5 drugs; 97%), ≥4 comorbidities (69%), and organ dysfunction (35%; P < .05). The safety and efficacy of ide-cel therapy were similar in younger and older patients. Frailty and geriatric characteristics such as polypharmacy, comorbidities, and organ dysfunction in older patients did not confer an inferior overall outcome.

Impact of Cognitive Impairment on Long-Term Outcomes After Transcatheter Aortic Valve Implantation

Background

Cognitive impairment assessed using the Mini-Mental Status Examination (MMSE) is associated with short-term mortality after transcatheter aortic valve implantation (TAVI). We assessed the long-term prognostic impact of cognitive impairment in patients with severe aortic stenosis post-TAVI.

Methods and Results

We enrolled 1,057 consecutive patients who underwent TAVI at the Kokura Memorial Hospital and prospectively assessed them using the MMSE. Results showed that 319 (30%) patients had cognitive impairment. Compared with normal cognition, cognitive impairment was associated with an increased risk for 5-year all-cause mortality (55% vs. 39%; P<0.001), cardiovascular mortality (23% vs. 14%; P=0.007), and non-cardiovascular mortality (42% vs. 29%; P<0.001). Multivariable analysis showed that cognitive impairment was independently associated with all-cause mortality (adjusted hazard ratio [aHR] 1.37; 95% confidence interval [CI] 1.10-1.70; P=0.005), and this result was consistent regardless of stratification based on age, sex, body mass index, left ventricular ejection fraction and clinical frailty scale without significant interaction. Patients with MMSE scores <16 had a significantly higher mortality rate compared with patients with MMSE scores >25, 21-25, and 16-20, respectively.

Conclusions

Cognitive impairment assessed using MMSE scores is independently associated with an increased risk for 5-year all-cause mortality in patients undergoing TAVI.

Frailty Detection in Older Adults with Diabetes: A Scoping Review of Assessment Tools and Their Link to Key Clinical Outcomes

Objectives: With the increasing prevalence of diabetes and frailty among older adults, there is an urgent need for precision medicine that incorporates comprehensive geriatric assessments, including frailty detection. This scoping review aims to map and synthesize the available evidence on validated tools for detecting pre-frailty and frailty in community-dwelling elderly individuals with diabetes and outpatient diabetes patients. Specifically, it addresses: (1) What validated tools are available for detecting pre-frailty and frailty in this population? (2) How are these tools associated with outcomes such as glycemic control, hypoglycemia, and metabolic phenotypes? (3) What gaps exist in the literature regarding these tools? Methods: The review followed PRISMA-ScR guidelines, conducting a systematic search across PubMed, Cochrane Library, and Web of Science. The inclusion criteria focused on studies involving individuals aged 70 years and older with diabetes, emphasizing tools with predictive capacity for disability and mortality. Results: Eight instruments met the inclusion criteria, including the Frailty Index, Physical Frailty Phenotype, and Clinical Frailty Scale. These tools varied in domains such as physical, psychological, and social aspects of frailty and their association with glycemic control, hypoglycemia, and metabolic phenotypes. The review identified significant gaps in predicting diabetes-related complications and their clinical application. Conclusions: Routine management of older adults with diabetes should incorporate frailty detection, as it is crucial for their overall health. Although widely used, the reviewed tools require refinement to address the unique characteristics of this population. Developing tailored instruments will enhance precision medicine, leading to more effective, individualized interventions for elderly individuals with diabetes.

Mediating Effects of Information Access on Internet Use and Multidimensional Health Among Middle-Aged and Older Adults: Nationwide Cross-Sectional Study

BACKGROUND

With the exacerbation of population aging, the health issues of middle-aged and older adults have increasingly become a focus of attention. The widespread use of the internet has created conditions for promoting the health of this demographic. However, little is known about the effects of information access in promoting the relationship between internet use and the health of middle-aged and older adults.

OBJECTIVE

This study aims to examine the relationship between internet use and multidimensional health in middle-aged and older adults, as well as the mediating effect of information access. Moreover, this study will explore the relationship between other dimensions of internet use (purposes and frequency) and health.

METHODS

Data were sourced from the China General Social Survey conducted in 2018. Health outcomes, including self-rated, physical, and mental health, were assessed using the 5-level self-rated health scale, the 5-level basic activities of daily living scale, and the 5-level depression scale, respectively. The ordinal logistic regression model was used to examine the relationship between internet use and health among middle-aged and older adults. Additionally, the Karlson-Holm-Breen decomposition method was used to examine the mediation effect of information access. To address endogeneity issues, the two-stage least squares approach was applied.

RESULTS

In our sample, nearly half (n=3036, 46.3%) of the respondents use the internet. Regression analyses revealed that internet use was positively associated with self-rated health (odds ratio [OR] 1.55, 95% CI 1.39-1.74; P<.001), physical health (OR 1.39, 95% CI 1.25-1.56; P<.001), and mental health (OR 1.33, 95% CI 1.19-1.49; P<.001) of middle-aged and older adults. Various dimensions of internet use positively contribute to health. In addition, information access significantly mediated the relationship between internet use and self-rated health (β=.28, 95% CI 0.23-0.32), physical health (β=.40, 95% CI 0.35-0.45), and mental health (β=.16, 95% CI 0.11-0.20). Furthermore, there were significant differences in the relationship between internet use and health among advantaged and disadvantaged groups.

CONCLUSIONS

The study showed that different dimensions of internet use are associated with better self-rated health, better physical health, and better mental health in middle-aged and older adults. Information access mediates the relationship between internet use and health. This result emphasizes the significance of promoting internet access as a means to enhance the health of middle-aged and older adults in China.

The association between the weight-adjusted-waist index and frailty in US older adults: a cross-sectional study of NHANES 2007-2018

Objective

This study aimed to evaluate the relationship between the weight-adjusted waist circumference index (WWI) and the frailty in American adults aged over 60 years.

Methods

We utilized data from the National Health and Nutrition Examination Surveys (NHANES) spanning from 2007 to 2018. WWI was calculated using the square root of waist circumference (cm) divided by body weight (kg). The frailty index ≥ 0.25 was employed to assess frailty. Weighted multivariate logistic regression was conducted to explore the association between WWI and frailty. Generalized Additive Modeling (GAM) was used to explore potential non-linear relationships. Receiver operating characteristic curve (ROC) analysis was used to assess the predictive ability of WWI for frailty.

Results

The study encompassed 7765 participants. Higher WWI was significantly associated with higher odds of frailty. In the fully adjusted model, each unit increase of WWI was associated with an 82% increased odds of frailty (OR: 1.82, 95% CI: 1.61 - 2.06; P < 0.001). GAM found significant nonlinear relationships and threshold effects.

Conclusion

The study presented a robust correlation between elevated WWI and increased odds of frailty among American older adults. However, these findings require further validation in large-scale, prospective studies.

Everyday ageism experienced by community-dwelling older people with frailty

PURPOSE

Ageism encapsulates stereotypes, prejudice and discrimination towards others or oneself based on age. While identified as the most frequent form of discrimination, relatively little work has captured the problem of day-to-day ageism faced by older people with frailty in community settings. The aim of this study therefore was to examine the prevalence of everyday ageism experienced by older people attending hospital-based ambulatory care services, and to clarify its association with measures of quality of life (QOL) and frailty.

METHODS

A consecutive series (n = 100) of patients aged ≥ 70 years attending ambulatory care completed focused interviews. Day-to-day experience of ageism was measured with the everyday ageism scale, QOL was measured with the control autonomy self-realisation pleasure scale.

RESULTS

Just over half of participants reported exposure to ageist messages; over 5/6 reported experiencing ageism in interpersonal interactions and 2/3 held some ageist beliefs themselves. Logistic regression demonstrated that experiencing ageism in interpersonal interactions was associated with a higher likelihood of internalised ageism [Adjusted Odds Ratio 6.02 (95% CI 1.70, 21.34); p = 0.005)]. Both ageism in interpersonal interactions [β = -5.22 (95% CI -9.52, -0.91); p = 0.018] and internalised ageism [β = -5.36 (95% CI -8.75, -1.97); p = 0.002] were associated with significantly lower QOL.

DISCUSSION

This study highlights the striking prevalence of everyday ageism experienced by a cohort of community-dwelling older people with frailty and multimorbidity. In the context of further projected demographic changes in coming decades, with increasingly higher proportions of older people worldwide, these findings highlight an important societal issue that needs to be addressed.

Frailty Is Associated With Increased Care Dependence in Patients Following Major Vascular Surgery

OBJECTIVE

To assess if frailty scoring can predict increased frailty and care dependence requiring a change in living situation in patients with peripheral artery disease (PAD) following major vascular surgery.

DESIGN

A single center, retrospective cohort study.

SETTING

Fiona Stanley Hospital, a tertiary center located in Perth, Western Australia.

PARTICIPANTS

Seventy-nine patients with PAD who underwent major vascular surgery at the study hospital in 2022 were enrolled.

INTERVENTION

Baseline Clinical Frailty Scale (CFS) scores were assigned retrospectively. A quantitative analysis using two partitions, CFS 1-3 (not frail) versus 4-9 (frail) was used. Cases were screened for hospital-acquired complications, and records were reviewed to assess the level of care dependence at the time of discharge and 6 months following.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was to assess if frailty predicts increased care dependence. Secondary outcomes included unplanned readmissions and hospital-acquired complications in this cohort. A logistic regression was performed to predict the effects of age and baseline, discharge, and 6-month CFS on the likelihood of change in living situation. Baseline frailty was associated with a higher frailty score at discharge (p = 0.001), which persisted at 6 months (p = 0.001). There was no difference in American Society of Anesthesiologists classification, sex, age, 30-day mortality, or in-hospital complications between groups. After correcting for age, a lower baseline CFS (odds ratio 0.19, confidence interval 0.04-0.84, p = 0.028) and discharge CFS (odds ratio 34.00, confidence interval 3.88-298.42, p = 0.001) predicts the likelihood of patients having a change in living situation after surgery.

CONCLUSIONS

Frail patients with PAD undergoing major vascular surgery are at significant risk of functional decline, necessitating a change in living situation to meet their increased care needs. This increased care dependence persisted 6 months following discharge.

Influence of Frailty Status on the Efficacy of Epidural Steroid Injections in Elderly Patients With Degenerative Lumbar Spinal Disease

Background: The global increase in the elderly population has led to a higher prevalence of degenerative lumbar spinal diseases. Epidural steroid injection (ESI) is a widely used procedure for managing lower back pain. This study investigated the association of preprocedural frailty status with the efficacy of ESI in elderly patients diagnosed with degenerative lumbar spinal diseases. Methods: This retrospective observational study included patients aged 65 years and older who underwent lumbar ESI. Frailty status (robust, prefrail, and frail) assessed via the Frailty Phenotype Questionnaire was collected along with demographic and clinical parameters. Good analgesia was defined as a ≥ 50% reduction in pain score at 4-week follow-up evaluation. Multivariable logistic regression analyses were performed to identify factors associated with poor analgesia. Results: We included 289 patients in this study. Frailty status correlated with analgesic outcomes, with worsening frailty status correlating with increasingly poor analgesia after the injection (robust = 34.5%, prefrail = 40.8%, and frail = 60.0%, p=0.003), predominantly in female patients. After adjusting for demographic and clinical factors, frail patients demonstrated much higher odds of poor analgesia than robust individuals (adjusted odds ratio [aOR] = 2.673, 95% confidence interval [CI] = 1.338-5.342, p=0.005). Conversely, prefrail patients did not show a significant association with analgesic outcome (aOR = 1.293, 95% CI = 0.736-2.272, p=0.372). Conclusions: Frailty, but not prefrailty, appeared to be an independent factor associated with poor analgesic efficacy of ESI in elderly patients with symptomatic degenerative lumbar spinal disease receiving conservative care.

The association of frailty with morbidity and mortality following major mucosal head and neck surgery

OBJECTIVES

Frailty refers to a state of reduced physiological reserve and functional decline. We sought to analyse whether frailty, assessed using the 5-item modified frailty index (5mFI), was associated with increased morbidity and mortality following major mucosal head and neck surgery.

MATERIALS AND METHODS

We performed a retrospective study of patients undergoing major mucosal head and neck surgical resection over a 2-year period. Potential confounding variables were controlled by way of multivariable regression analysis.

RESULTS

There were 310 patients included with 77 (24.8 %) classified as frail. Most patients were male (219/310, 70.7 %), had a history of smoking (246/310, 79.4 %) and 151 patients (48.7 %) were older than 65 at time of surgery. Most surgeries related to oral cavity or oropharyngeal subsites (227/310, 73.2 %) and 150 patients (48.4 %) underwent microvascular free tissue reconstruction. On multivariable analysis, frail patients were more likely to suffer adverse outcomes such as a return to theatre (OR 3.47, 95 % CI 1.82-6.62, p < 0.001), a Clavien-Dindo grade IV complication (OR 6.23, 95 % CI 2.55-15.20, p < 0.001) or medical complications, such as respiratory complications (OR 2.61, 95 % CI 1.45-4.69; p = 0.001) or delirium (OR 5.05, 95 % CI 2.46-10.33; p < 0.001). Additionally, hospital length of stay was increased among frail patients (ß 16.46 days, 95 % CI 9.85-23.07 days; p < 0.001). Neither 90-day nor 1-year post-operative mortality was increased in frail patients.

CONCLUSION

Frailty assessed using the 5mFI was associated with greater post-operative morbidity, but not mortality following major mucosal head and neck surgery.

The relationship between social frailty and cognitive impairment among older adults: the role of various types of internet use

Introduction

This study aimed to explore the role of internet use in the relationship between social frailty and cognitive function among Korean older adults.

Methods

A nationally representative survey of community-dwelling older adults in Korea was used in the analysis (N = 8,639).

Results

All types of internet use were significantly associated with cognitive impairment and played a significant role in the relationship between social frailty and cognitive impairment. The advantage of internet use for information searching (OR 0.40, 95% CI 0.35-0.46) was the greatest for cognitive function, followed by internet use for instrumental use (OR 0.59, 95% CI 0.53-0.66). Internet use for entertainment exhibited the greatest influence in the relationship between social frailty and cognitive impairment, with interpersonal communication ranking second in significance. Internet use regulates the relationship between social frailty and cognitive impairment in older adults. The influences of internet use vary depending on the type of online activity and the levels of social frailty.

Discussion

This highlights the importance of considering various forms of internet use when developing non-pharmacological interventions to mitigate the impact of social frailty on cognitive decline.

Defining an Ageing-Related Pathology, Disease or Syndrome: International Consensus Statement

Background

Around the world, individuals are living longer, but an increased average lifespan does not always equate to an increased healthspan. With advancing age, the increased prevalence of ageing-related diseases can have a significant impact on health status, functional capacity, and quality of life. It is therefore vital to develop comprehensive classification and staging systems for ageing-related pathologies, diseases and syndromes. This will allow societies to better identify, quantify, understand, and meet the healthcare, workforce, wellbeing, and socioeconomic needs of ageing populations, while supporting the development and utilisation of interventions to prevent or to slow, halt or reverse the progression of ageing-related pathologies.

Methods

The foundation for developing such classification and staging systems is to define the scope of what constitutes an ageing-related pathology, disease or syndrome. To this end, a consensus meeting was hosted by the International Consortium to Classify Ageing-Related Pathologies (ICCARP), on February 19 th , 2024, in Cardiff, UK, and was attended by 150 recognised experts. Discussions and voting were centred on provisional criteria that had been distributed prior to the meeting. The participants debated and voted on these. Each criterion required a consensus agreement of ≥70% for approval.

Results

The accepted criteria for an ageing-related pathology, disease or syndrome were: Develops and/or progresses with increasing chronological age.Should be associated with, or contribute to, functional decline, or an increased susceptibility to functional decline.Evidenced by studies in humans.

Conclusions

Criteria for an ageing-related pathology, disease or syndrome have been agreed by an international consortium of subject experts. These criteria will now be used by the ICCARP for the classification and ultimately staging of ageing-related pathologies, diseases and syndromes.

"They forget that I'm a human being"-ward round communication with older patients living with frailty and informal caregivers: a qualitative study

PURPOSE

Skilful communication prompts quality patient care. Informal caregivers occupy a crucial role when caring for hospitalised older patients living with frailty. However, skilful communication with both patients and informal caregivers during ward rounds has not been studied. Thus, we aimed to explore communication preferences of patients and informal caregivers during ward rounds.

METHODS

We conducted semi-structured interviews with hospitalized patients and informal caregivers until information redundancy occurred. We used inductive coding of the transcribed interviews followed by a reflexive thematic analysis.

RESULTS

The study included 15 patients and 15 informal caregivers. Patients had a median age of 85 years (range 75-100 years) and seven patients were females. Informal caregivers' median age were 45 years (range 38-80 years) and 13 were females. Three themes were generated: (1) building relationships and conveying information, (2) alleviating informal caregiver strain and (3) sharing the decision-making process. Themes highlighted the importance of collaborative and empathetic approaches in healthcare interactions, emphasizing interpersonal communication skills, such as fostering professional relationships. The interviews unveiled informal caregiver burden stemming from disempowerment during hospital discharge process and managing mistrust within the healthcare system. The shared decision-making process should address patients' and informal caregivers' needs and circumstances.

CONCLUSIONS

Communication preferences of a population of older patients living with frailty and informal caregivers during ward rounds encompass interpersonal communication, demonstrating ample time, and being seen as a human being. Informal caregivers value being included in the decision-making process. Skilful communication includes for doctors to recognize informal caregivers' narratives and burdens.

Understanding the Role of Oxidative Stress in Platelet Alterations and Thrombosis Risk among Frail Older Adults

Frailty and cardiovascular diseases are increasingly prevalent in aging populations, sharing common pathological mechanisms, such as oxidative stress. The evidence shows that these factors predispose frail individuals to cardiovascular diseases but also increase the risk of thrombosis. Considering this background, this review aims to explore advances regarding the relationship between oxidative stress, platelet alterations, and cardiovascular diseases in frailty, examining the role of reactive oxygen species overproduction in platelet activation and thrombosis. The current evidence shows a bidirectional relationship between frailty and cardiovascular diseases, emphasizing how frailty not only predisposes individuals to cardiovascular diseases but also accelerates disease progression through oxidative damage and increased platelet function. Thus, oxidative stress is the central axis in the increase in platelet activation and secretion and the inadequate response to acetylsalicylic acid observed in frail people by mitochondrial mechanisms. Also, key biomarkers of oxidative stress, such as isoprostanes and derivate reactive oxygen metabolites, can be optimal predictors of cardiovascular risk and potential targets for therapeutic intervention. The potential of antioxidant therapies in mitigating oxidative stress and improving cardiovascular clinical outcomes such as platelet function is promising in frailty, although further research is necessary to establish the efficacy of these therapies. Understanding these mechanisms could prove essential in improving the health and quality of life of an aging population faced with the dual burden of frailty and cardiovascular diseases.
