Insulin-like Growth Factor-1 Levels Reflect Muscle and Bone Health and Determine Complications and Mortality in Decompensated Cirrhosis.

Background: The growth hormone-insulin-like growth factor (GH-IGF-1) axis and its impairment with sarcopenia, frailty, bone health, complications, and prognosis are not well characterized in cirrhosis. Methods: We investigated the adult decompensated cirrhosis out-patients at a tertiary care institute between 2021 and 2023 for serum GH and IGF-1 levels, and associated them with sarcopenia (CT-SMI in cm2/m2), liver frailty index (LFI), osteodystrophy (DEXA), clinical decompensations (overall, ascites, encephalopathy, infection, and bleed), and survival up to 180 days. Results: One-hundred-seventy-two patients, 95% males, aged 46.5 years (median). logIGF-1 levels were negatively associated with sarcopenia, osteodystrophy, LFI, CTP, and MELD-Na score (P < 0.05 each). Patients with low IGF-1 levels had a higher incidence of complications (overall, ascites and encephalopathy) than those with intermediate, and high IGF-1 levels (P < 0.05 each). Both logIGF-1 (AUC: 0.686) and MELD (AUC: 0.690) could predict 180-day mortality (P < 0.05, each). Adding logIGF-1 with MELDNa further improved discriminative accuracy of MELDNa (AUC: 0.729) P < 0.001. The increase in IGF-1 on follow-up was associated with better survival and fewer complications. Conclusion: Reduced IGF-1 levels reflect sarcopenia, frailty, and osteodystrophy in cirrhosis. Low IGF-1 are associated with severity, development of decompensations, and mortality.

A Hybrid Concept Analysis of Frailty Among Older Adults Living in the Community.

AIM: To analyse the concept of frailty through a literature review and in-depth interviews. DESIGN: A hybrid model of concept analysis. METHODS: The theoretical phase identified 43 articles for reviewing the definition and measurement of frailty. Seven frail older adults were invited in the fieldwork phase for in-depth interviews. In the final analysis phase, results from the fieldwork and theoretical phases were integrated to obtain a final definition of frailty. RESULTS: Attributes of frailty were heterogeneous, involving dynamic/bidirectional, multidimensional and multiple systems. The antecedents of the concept were exposure to various stimuli and challenges in responding to these stimuli. Consequences included losing autonomy and adverse health outcomes. Four themes of frailty were identified based on the fieldwork data: 'accumulation of functional decline', 'powerlessness of coping with', 'vicissitudes of lived experience' and 'loss of autonomy and positivity'. CONCLUSIONS: The final definition of frailty was 'a dynamic and fluctuating process of powerlessness to manage biopsychosocial and environmental stimuli, involving functional decline and vicissitudes of life, which results in losing autonomy and positivity or adverse health outcomes'. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Characterising the definition of frailty is essential for nurses to address the lived experiences of older adults when providing person-centred care and for developing interventions that meet the needs of frail older adults. IMPACT: Since some discrepancies existed in the definition of frailty from individual perception of older adults, combined in-depth interviews with a theoretical literature review were used to provide comprehensive insight. This concept analysis provides guidelines of training for nurses and opportunities to improving quality of life for community dwelling older adults. REPORTING METHOD: N/A.

Knee joint dysfunction in the patients immediately before arthroplasty was well reflected by locomotive syndrome, not physical frailty.

OBJECTIVES: We assessed physical function by three different methods in patients with knee osteoarthritis just before total knee arthroplasty (TKA) and investigated the relationship between impairment of mobility and preoperative factors. METHODS: All patients scheduled to undergo TKA at our hospital were assessed for basic attributes, clinical assessment, radiography, whole-body mode DXA, knee muscle strength. And frailty, sarcopenia, and locomotive syndrome (LS) were evaluated. RESULTS: Among 204 patients (213 knees),172 women, mean age 75.0 years, the overall distribution in frailty was ; in sarcopenia ; and in LS . Eighty-seven percent of the patients with frailty and 92% with LS stage 3 did not suffer from sarcopenia. Statistically significant relationships were observed between sarcopenia and frailty, while no relationship between LS and frailty or LS and sarcopenia. Multivariate analysis of related factors with severity level for frailty and LS revealed statistically significant correlations for frailty with gait speed and LS with KSS and muscle strength. CONCLUSION: In the patients with knee OA immediately before arthroplasty, physical frailty and LS was not related with by sarcopenia. Knee joint dysfunction without sarcopenia was well reflected by LS, not by physical frailty.

Effects of intervention by trained care managers on advance care planning engagement among long-term care service users in Japan: a pre- and post-pilot comparative study across multiple institutions.

Background: A majority of Japanese care managers lack medical qualifications, feel uncomfortable discussing future medical choices and believe that it is not their responsibility. Objectives: As there is a paucity of care manager intervention studies, this study aimed to measure changes in advance care planning engagement among long-term care service users before and after intervention by care managers with communication training. Design: A multi-institutional pre- and post-pilot comparative study. Methods: A multi-institutional pre- and post-trial study was performed from August 2022 to January 2023 (trial ID: 000048573). Nine trained care managers communicated with 30 long-term care service users regarding advance care planning, and the pre- and post-trial advance care planning engagement scores were compared. Additionally, the post-trial impact of events score was investigated. Results: All 30 long-term care service users completed the trial. The advance care planning engagement score increased after the trial. The sample size was considered adequate for future trials. Years of experience as a care manager, impact of events score, and having a clinical frailty scale of ⩾5 were significant explanatory variables that affected the objective variable of the difference between pre- and post-trial advance care planning engagement score. Conclusion: This study on the impact of advance care planning communication interventions by trained care managers offers insights into determining appropriate sample sizes and identifying factors influencing future research outcomes. Advance care planning engagement of long-term care service users might change before and after intervention by care managers through advance care planning communication.

Frailty and health-related life quality in long-term follow up of intensive care patients above 65 years old: Protocol for a Norwegian prospective, observational multicenter study.

BACKGROUND: Frailty is strongly correlated with mortality in intensive care unit patients, yet routine screening among intensive care patients is rarely performed. The aim of this study is to assess frailty and health-related quality of life (HRQoL) in patients before intensive care admission and to compare this with outcomes after 3 and 12-months. The Clinical Frailty Scale and EQ-5D-5L will be used to assess frailty and HRQoL, respectively. METHODS: This is an ongoing, prospective observational study including patients from five Norwegian ICU's. Inclusion criteria are patients aged ≥65 years requiring invasive mechanical ventilation for ≥24 h. The Clinical Frailty Scale and EQ-5D-5L are administered at baseline (before critical illness) and at 3- and 12-months post-inclusion. Additional data collected includes patient characteristics, ICU treatment details, illness severity and mortality. The EQ-5D-5L will be compared to Norwegian population norms and assessed for measurement properties. RESULTS: Inclusion started July 2022 and will be stopped at 350 patients. The study will be completed in 2025. CONCLUSION: The study will assess the feasibility and measurement properties of the Clinical Frailty Scale and EQ-5D-5L in ICU survivors by telephone at long-term follow-up study and will give additional information on the frailty and HRQoL of intensive care survivors. CLINICAL TRIAL REGISTRATION: The study is registered in ClinicalTrials.gov NCT06012942. Protocol version 2.7.1, 19.05.2023.

Impact of tailored message notifications for frailty prevention in older adults: a quasi-randomized controlled study using a regression discontinuity design.

[Purpose] This study investigated the potential of tailored message notifications based on municipal health check-up results to improve pre-frailty and frailty in older adults. [Participants and Methods] This study was conducted in Iiyama City, Nagano Prefecture, Japan, by using the Kihon Checklist to assess the health status of older adults. Since 2019, Iiyama City has sent notifications to individuals with pre-frailty (Kihon Checklist score: 4-7) and frailty (Kihon Checklist score: ≥8). A regression discontinuity design was used to estimate the effects of the intervention by comparing the groups with scores just above and below the cutoff points. Data from 6,382 individuals aged ≥65 years from 2019 to 2022 were analyzed. [Results] The intervention slightly improved the Kihon Checklist scores in the pre-frailty group. No statistically significant effects were observed in the frailty group or after multiple imputations for missing data. [Conclusion] The findings suggest that tailored message notifications can improve frailty prevention among pre-frail older adults. However, the limited frequency and content of these messages may have reduced their effectiveness. Therefore, more frequent and targeted messages are needed to address the needs of frail individuals.

A Novel Scale System Based on the Frailty Index and Laboratory Indicators for the Short-Term Prognosis of Patients with Acute Myocardial Infarction: A Retrospective Cohort Study.

Objective: Current scoring systems for short-term prognosis in patients with acute myocardial infarction (AMI) lack coverage of risk factors and have limitations in risk stratification. The aim of this study was to develop a novel assessment system based on laboratory indicators and frailty quantification to better infer short-term prognosis and risk indication in patients with AMI. Methods: A total of 365 patients with MI from January 2022 to June 2023 in Northern Jiangsu Province Hospital were included. The primary endpoint was all-cause mortality and major adverse cardiac events (MACE) during follow-up. A novel scoring model ranging from 0 to 12 was constructed, and the predictive ability of this scoring system was evaluated using the area under the receiver operating characteristic curve (AUC). Results: During follow-up, 68 patients experienced MACE. Five scoring indicators were selected through multivariate logistic regression analysis, resulting in a composite score with an AUC of 0.925, demonstrating good prognostic accuracy. Conclusion: The novel prognostic assessment system, which integrates age, Stress Hyperglycemia Ratio (SHR), Neutrophil to Lymphocyte Ratio (NLR), lactate, and frailty score, exhibits good predictive value for short-term MACE in patients with acute myocardial infarction and may enable more accurate risk classification for future use in MI patient risk management.

Frailty, Body Composition, and Glycemic Control in Older Adults with Type 2 Diabetes.

The relationship between frailty and glycemic control in older adults with diabetes remains uncertain, mainly due to the fact that previous studies have not accounted for measures of body composition. In older adults with diabetes, we examined the association between three types of frailty measures and glycemic control, while accounting for fat-free mass (FFM) and waist circumference (WC). Eighty older adults (age ≥65, 27 women and 53 men, mean age 80.5 ± 0.6 years) had gait speed, Cardiovascular Health Study Index (CHSI), Rockwood Clinical Frailty Scale (RCFS), and glycosylated hemoglobin (HgA1C) measured. HgA1C showed a negative association only with CHSI (standardized ß = -0.255 ± 0.120, p = 0.038), but no association with gait speed or the RCFS. Even after accounting for FFM and WC, we demonstrated a negative association between glycated hemoglobin and increasing frailty in older adults with diabetes.

Effect of non-pharmacological interventions in people with cognitive frailty: a systematic review and network meta-analysis.

ABSRTACT: OBJECTIVE: To evaluate the effects of various non-pharmacological interventions on patients with cognitive impairment by systematic search and network meta-analysis, and to rank the effects of the included non-pharmacological interventions. METHODS: The databases of PubMed, Cochrane Library, EMbase, Web of Science, CNKI, VIP, WANFANG, and SinoMed were searched by computer. All randomized controlled trials (RCTs) of non-pharmacological interventions for people with cognitive frailty were collected. The search was conducted from 2000 to February 2024. Two reviewers independently screened the studies, extracted data, and assessed the risk of bias of the included studies, and then used Stata15 and R4.3.1 software to conduct network meta-analysis, with physical function and cognitive function as the main outcome indicators. RESULTS: A total of 19 randomized controlled trials involving 1738 patients were included. The results of network meta-analysis showed that among the non-pharmacological interventions, nutritional support had the best effect on improving frailty scores and cognitive function scores in patients with cognitive frailty. Aerobic training combined with resistance training is best for improving grip strength. For improving the patient's motor status, cognitive training had the best effect on improving TUG test scores. High-speed resistance training is best for improving walking speed. CONCLUSION: This review analyses the current study of non-pharmacological interventions to improve physical performance in patients with cognitive frailty. Current evidence suggests that nutritional support is most effective at improving physical frailty and cognitive decline in patients with cognitive frailty, and that exercise and cognitive training interventions significantly improve grip strength and motor ability. TRIAL REGISTRATION: This meta-analysis was prospectively registered with PROSPERO (registration number: CRD42023486881).

Association of preoperative frailty with risk of postoperative delirium in older patients undergoing craniotomy: a prospective cohort study.

BACKGROUND: Preoperative frailty is a risk factor associated with postoperative delirium (POD), which has attracted more attention from clinicians, but no research has shown that it is related to elderly patients undergoing craniotomy. Therefore, the aim of this study was to determine the effect of preoperative frailty on POD in older patients, especially those who underwent craniotomy. METHODS: From October 2022 to May 2023, older patients who underwent elective craniotomy were collected. Assess the occurrence of frailty using the FRAIL scale one day before surgery. Evaluate the occurrence of POD using the Confusion Assessment Method (CAM) within three days after surgery. Participants were divided into two groups, one group being POD, Logistic regression analysis was used to find the risk variables for POD, and the predictive value of preoperative frailty to POD was determined by using the operating characteristic curve of the subjects. RESULTS: A total of 300 patients were included in this study, among whom 83 patients (27.7%) exhibited preoperative frailty and 69 patients (23.0%) experienced POD. The results of the multivariate logistic regression analysis indicate that preoperative frailty (OR: 8.816, 95% CI: 3.972-19.572), preoperative hypoalbuminemia (OR: 0.893, 95% CI: 0.811-0.984), low BMI (OR: 0.793, 95% CI: 0.698-0.901), and prolonged operative duration (OR: 1.007, 95% CI: 1.004-1.010) are independent risk factors for POD in older patients who underwent craniotomy. We constructed a risk prediction model using these factors, which had an area under the ROC curve of 0.908 (95% CI: 0.869-0.947, P < 0.001). Preoperative frailty enhanced the discriminative ability of the prediction model by 0.037. POD was associated with a longer length of hospital stay and higher hospitalization costs. CONCLUSIONS: Preoperative frailty is an independent risk factor for POD in older patients undergoing elective craniotomy and can predict the occurrence of POD to a certain extent. In addition, early identification of patients at risk of malnutrition and appropriate surgical planning can reduce the incidence of POD.

Association of dietary inflammatory index, composite dietary antioxidant index, and frailty in elderly adults with diabetes.

BACKGROUND: We aimed to examine the relationship of 2 dietary scores [dietary inflammatory index (DII) and composite dietary antioxidant index (CDAI)] with frailty in elderly adults with diabetes. METHODS: Data were gathered from the National Health and Nutrition Examination Survey (NHANES) between 2007 and 2018. The frailty index was calculated using 49 deficits across various systems to define frailty. To examine the relationship of 2 dietary scores (DII and CDAI) with frailty in elderly adults with diabetes, multiple logistic regression analyses were performed. In logistic regression model, DII and CDAI were calculated as both continuous and tertiles. Subgroup analyses were performed to demonstrate stability of results. Restricted cubic splines were utilized to examine the non-linear correlations. RESULTS: A total of 2,795 elderly adults with diabetes were included in this study. In the multivariate logistic regression model, the odds ratio (OR) of DII for risk of frailty was 1.08 (95% CI 1.02-1.15) and the OR of CDAI for risk of frailty was 0.96 (95% CI 0.93-0.99). The ORs of DII for risk of frailty were 1.36 (95% CI 1.09-1.70) and 1.33 (95% CI 1.04-1.70) for tertiles 2 and 3, respectively (p for trend 0.027). The ORs of CDAI for risk of frailty were 0.94 (95% CI 0.75-1.17) and 0.75 (95% CI 0.58-0.98) for tertiles 2 and 3, respectively (p for trend 0.036). The subgroup analysis demonstrated reliable and enduring connections between 2 dietary scores and frailty (all p for interaction > 0.05). In the restricted cubic spline analyses, we discovered the non-linear relationship between DII and frailty (P for nonlinearity = 0.045) and linear relationship between CDAI and frailty (P for nonlinearity = 0.769). CONCLUSION: The research showed connections between 2 dietary scores (DII and CDAI) and frailty as measured by frailty index in elderly adults with diabetes.

Depression and Plasma pTau181 Levels Are Associated with Frailty Status in Hispanic Community-Dwelling Older Women.

The population of Hispanic older adults is growing along with the burden of chronic diseases. This cross-sectional study aims to assess the factors associated with frailty among community-dwelling Hispanic women aged ≥60 years (n = 357) enrolled in the Panama Aging Research Initiative-Health Disparities study of cognitive-functional health of older persons in Panama. Cognitive function was assessed with a neuropsychological test battery. Depression was measured with the Geriatric Depression Scale. Frailty was defined using the Fried criteria and participants were classified as non-frail, pre-frail or frail. A subsample (n = 281) provided fasting blood samples for quantification of protein biomarkers. Associations were examined using hierarchical multiple linear regressions. 59.4% and 9.0% of participants (M = 69.2 years, SD = 6.3) were pre-frail and frail, respectively. Having more depression (ß = .28, p < .001) was significantly associated with frailty, even after covariate adjustment. Cognitive function was not associated with frailty. Higher pTau181 levels were associated with increased frailty (ß = .13, p = .039), whereas higher α2M levels were associated with decreased frailty (ß = -.16, p = .004). These findings advance the search for health indicators and biomarkers of frailty and warrant further studies to decrease the burden of frailty among older Hispanic women.

Feasibility of a problem-solving exercise program based on short physical performance battery for older patients with chronic respiratory diseases: A multicenter, pilot clinical trial.

BACKGROUND: This study aimed to assess the feasibility and safety of a problem-solving exercise program based on the items in the short physical performance battery (SPPB) for older patients with chronic respiratory diseases (CRDs) to inform future randomized controlled trials. METHODS: This was a multicenter, prospective, non-randomized feasibility study. Participants with CRD received an enhancement program based on the SPPB decline items (balance, walk, and/or chair stand) for 4 weeks. The feasibility, safety, and efficacy of the problem-solving exercise program in improving the SPPB score, physical function, and step count (measured using a pedometer) were assessed. RESULTS: Overall, 36 patients were enrolled in this study, and adherence to the exercise program was high (100%). No exercise program-related adverse events were observed. The implementation of the exercise program ranged from 70 to 100%. The mean daily step count increased from 2152 ± 1498 steps during the first week to 2899 ± 1865 steps in the last week (p<0.01). Additionally, the SPPB total score increased from 8.9 ± 1.8 points to 10.7 ± 1.3 points at the end of the program (p<0.001). CONCLUSIONS: The problem-solving exercise program based on SPPB is feasible and safe for older patients with CRDs. However, the effectiveness of this exercise program should be validated in large-scale, randomized-controlled trials in the future. TRIAL REGISTRATION: University Hospital Medical Information Network Center (UMIN-CTR) UMIN: approval number: UMIN000048761.

Multidomain Intervention for the Reversal of Cognitive Frailty Using a Personalized Approach (AGELESS Trial): Recruitment and Baseline Characteristics of Participants.

BACKGROUND: Reversal of cognitive frailty through a multidomain intervention is desirable to prevent dementia. AGELESS Trial was conducted to determine the effectiveness of a comprehensive, multidomain intervention on older adults with cognitive frailty in Malaysia. However, conducting a clinical trial, particularly during and after Covid-19, posed unique challenges. OBJECTIVE: We aimed to investigate the recruitment process and baseline characteristics of the AGELESS Trial participants to better understand an at-risk population and those who agree to participate in an intervention. DESIGN/SETTING: 24-month, randomized controlled trial. PARTICIPANTS: Community-dwelling older adults with independent mobility, aged ≥ 60 years, with a mini mental state examination score of 19-25, a clinical dementia rating of 0.5 ≥ 1 Fried's physical frailty criteria, and < 22 Beck depression inventory. INTERVENTION: Participants were randomized 1:1 to a structured multidomain intervention consisting of vascular management, diet, exercise, cognitive and psychosocial stimulation, or to the arm, including routine care and general health consultation. MEASUREMENT: We analyzed the group differences between (1) cognitive frailty and non- cognitive frailty screened subjects, (2) recruited and non-recruited participants, (3) baseline characteristics of participants by arm, (4) adherence to AGELESS intervention at 12 months, and (5) preliminary findings on the effectiveness of the intervention at 12 months. RESULTS: A total of 957 older adults from two locations, i.e., urban (n = 764) and rural (n = 193) areas, were screened, of whom 38.9% had cognitive frailty and were eligible to participate. Those with cognitive frailty had fewer years of education (B = -0.08; 95%CI = 0.88-0.97; p = 0.002), and lower functioning cognition (B = -0.24; 95%CI = 0.74-0.84; p < 0.001). Among those from urban areas, only 33.1% (n = 106) agreed to participate, particularly those with multimorbidity (B = 0.86; 95%CI = 1.31-4.30; p = 0.01), higher physical activity (B = -1.02; 95%CI = 0.19-0.69; p = 0.002), slower walking speed (B = 1.26; 95%CI = 1.62-7.61; p = 0.001), and higher systolic blood pressure (B = 0.02; 95%CI = 1.00-1.03; p = 0.03). At baseline, participants' mean age was 68.1±5.6, years of education was 8.3±3.9, body mass index was 27.5±5.3 kg/m2, and mini mental state examination score was 22.7±4.0. Generally, there were no significant differences between the intervention and control groups for the main outcomes, except those in the intervention group had higher body mass index, mid-upper-arm circumference, and waist circumference (p < 0.05 for all parameters). Overall intervention adherence at 12 months was 52.8%, ranging from 52.8%-90.6% for each of the modules. Preliminary analysis of the effectiveness of the intervention at 12 months was positive on most of the cognitive domains, some of the nutrient intake and food groups, physical function, and vascular outcomes (p < 0.05 for all parameters). CONCLUSION: Despite the challenges posed by the pandemic, screening, recruitment, and 12-month intervention delivery were achieved in a Malaysian multidomain preventive randomized controlled trial in older adults at risk of dementia, with a satisfactory adherence rate and cognitive benefits at 12 months.

Moderate physical activity and higher frequency are inversely associated with incidence of frailty in middle-aged and older population: a 4-year longitudinal study in Europe.

BACKGROUND: Global aging is leading to an increase in frailty patients, and physical activity (PA) may have an impact on frail in middle-aged and older population. This study aimed to explore the relationship between the frequency of different PA intensities and the incidence and prevalence of frailty in middle-aged and older adults based on the Survey of Health, Ageing, and Retirement in Europe (SHARE). METHOD: Self-reported questionnaires were used to obtain information on demographics and PA, and frailty was assessed using the SHARE Frailty Instrument (SHARE-FI). Cox regression and logistic regression models were used to explore the association between PA and frailty and stratified according to middle or old age. RESULTS: Among 6315 baseline non-frail participants aged 44-96 years, 16.1% developed frailty over 4 years, with higher incidence and prevalence in women (P < 0.05). Women accounting for 55.80% of the sample. The frequency of participants participating in sports decreased over 4 years (P < 0.05). Compared with participants who engaged in PA more than once a week, participants who engaged in moderated PA less frequently had a higher risk of new-onset frailty (HR: 3.174-6.115), and participants who engaged in vigorous PA 1-3 times a month had a higher risk of new-onset frailty (HR: 1.335). Participation in low-frequency moderate PA and vigorous PA 1-3 times per month were positively associated with the prevalence of frailty (P < 0.05). CONCLUSION: Physical activity frequency decreases with age in middle-aged and older adults. Those adults who engage in moderate PA more than once a week have a lower risk of incidence of frailty, compared to those with more sedentary life-styles. Additionally, women need to pay more attention to frailty management.

Frailty; Time for Global Action : Commentary on "Frailty and its Association with Long-Term Mortality among Community-Dwelling older adults aged 75 years and Over".

This commentary examines the study "Frailty and Its Association with Long-Term Mortality Among Community-Dwelling Older Adults Aged 75 Years and Over" by Lewis et al. The retrospective cohort study utilized data from a primary healthcare provider in Israel to investigate frailty using the Frailty Index (FI) and its correlation with long-term mortality. Nearly half of the older adult cohort was identified as frail, with a strong association between higher frailty levels and increased mortality risk. The commentary emphasizes the importance of routine frailty screening in clinical practice and health policy. Integrating FI calculations into electronic health records can facilitate timely care for high-risk individuals. However, presenting frailty data must be managed carefully and in conjunction with patients' preferences to avoid stigmatizing and negatively influencing clinical decisions. While the FI is a valuable tool, it should complement, not replace, other assessments that provide a more holistic view of the patient's health. Furthermore, the commentary strongly advocates for a more comprehensive approach to patient care, emphasizing that non-geriatricians must also be proficient in recognizing and managing frailty. Effectively addressing frailty can lead to significant cost savings for healthcare systems, reduced burden on healthcare facilities, and decreased need for long-term care.

Development and validation of an explainable machine learning model for predicting multidimensional frailty in hospitalized patients with cirrhosis.

We sought to develop and validate a machine learning (ML) model for predicting multidimensional frailty based on clinical and laboratory data. Moreover, an explainable ML model utilizing SHapley Additive exPlanations (SHAP) was constructed. This study enrolled 622 patients hospitalized due to decompensating episodes at a tertiary hospital. The cohort data were randomly divided into training and test sets. External validation was carried out using 131 patients from other tertiary hospitals. The frail phenotype was defined according to a self-reported questionnaire (Frailty Index). The area under the receiver operating characteristics curve was adopted to compare the performance of five ML models. The importance of the features and interpretation of the ML models were determined using the SHAP method. The proportions of cirrhotic patients with nonfrail and frail phenotypes in combined training and test sets were 87.8% and 12.2%, respectively, while they were 88.5% and 11.5% in the external validation dataset. Five ML algorithms were used, and the random forest (RF) model exhibited substantially predictive performance. Regarding the external validation, the RF algorithm outperformed other ML models. Moreover, the SHAP method demonstrated that neutrophil-to-lymphocyte ratio, age, lymphocyte-to-monocyte ratio, ascites, and albumin served as the most important predictors for frailty. At the patient level, the SHAP force plot and decision plot exhibited a clinically meaningful explanation of the RF algorithm. We constructed an ML model (RF) providing accurate prediction of frail phenotype in decompensated cirrhosis. The explainability and generalizability may foster clinicians to understand contributors to this physiologically vulnerable situation and tailor interventions.

Multimorbidity and the risk of malnutrition, frailty and sarcopenia in adults with cancer in the UK Biobank.

BACKGROUND: Malnutrition, sarcopenia and frailty are distinct, albeit interrelated, conditions associated with adverse outcomes in adults with cancer, but whether they relate to multimorbidity, which affects up to 90% of people with cancer, is unknown. This study investigated the relationship between multimorbidity with malnutrition, sarcopenia and frailty in adults with cancer from the UK Biobank. METHODS: This was a cross-sectional study including 4122 adults with cancer (mean [SD] age 59.8 [7.1] years, 50.7% female). Malnutrition was determined using the Global Leadership Initiative on Malnutrition criteria. Probable sarcopenia and sarcopenia were defined using the European Working Group on Sarcopenia in Older People 2 criteria. (Pre-)frailty was determined using the Fried frailty criteria. Multimorbidity was defined as ≥2 long-term conditions with and without the cancer diagnosis included. Logistic regression models were fitted to estimate the odds ratios (ORs) of malnutrition, sarcopenia and frailty according to the presence of multimorbidity. RESULTS: Genitourinary (28.9%) and breast (26.1%) cancers were the most common cancer diagnoses. The prevalence of malnutrition, (probable-)sarcopenia and (pre-)frailty was 11.1%, 6.9% and 51.2%, respectively. Of the 11.1% of participants with malnutrition, the majority (9%) also had (pre-)frailty, and 1.1% also had (probable-)sarcopenia. Of the 51.2% of participants with (pre-)frailty, 6.8% also had (probable-)sarcopenia. No participants had (probable-)sarcopenia alone, and 1.1% had malnutrition, (probable-)sarcopenia plus (pre-)frailty. In total, 33% and 65% of participants had multimorbidity, including and excluding the cancer diagnosis, respectively. The most common long-term conditions, excluding the cancer diagnosis, were hypertension (32.5%), painful conditions such as osteoarthritis or sciatica (17.6%) and asthma (10.4%). Overall, 80% of malnourished, 74% of (probable-)sarcopenia and 71.5% of (pre-)frail participants had multimorbidity. Participants with multimorbidity, including the cancer diagnosis, had higher odds of malnutrition (OR 1.72 [95% confidence interval, CI, 1.31-2.30; P < 0.0005]) and (pre-)frailty (OR 1.43 [95% CI 1.24-1.68; P < 0.0005]). The odds increased further in people with ≥2 long-term conditions in addition to their cancer diagnosis (malnutrition, OR 2.41 [95% CI 1.85-3.14; P < 0.0005]; (pre-)frailty, OR 2.03 [95% CI 1.73-2.38; P < 0.0005]). There was little evidence of an association of multimorbidity with sarcopenia. CONCLUSIONS: In adults with cancer, multimorbidity was associated with increased odds of having malnutrition and (pre-)frailty but not (probable-)sarcopenia. This highlights that multimorbidity should be considered a risk factor for these conditions and evaluated during nutrition and functional screening and assessment to support risk stratification within clinical practice.
