Arch Gerontol Geriatr 2024; 117:105175. [PMID: 37688921 DOI: 10.1016/j.archger.2023.105175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 08/11/2023] [Accepted: 08/30/2023] [Indexed: 09/11/2023]
Abstract
BACKGROUND Biological age (BA) has been used to assess individuals' aging conditions. However, few studies have evaluated BA models' applicability in centenarians. METHODS Important organ function examinations were performed in 1798 cases of the longevity population (80∼115 years old) in Hainan, China. Eighty indicators were selected that responded to nutritional status, cardiovascular function, liver and kidney function, bone metabolic function, endocrine system, hematological system, and immune system. BA models were constructed using multiple linear regression (MLR), principal component analysis (PCA), Klemera and Doubal method (KDM), random forest (RF), support vector machine (SVM), extreme gradient boosting (XGBoost), and light gradient boosting machine (lightGBM) methods. A tenfold crossover validated the efficacy of models. RESULTS A total of 1398 participants were enrolled, of whom centenarians accounted for 49.21%. Seven aging markers were obtained, including estimated glomerular filtration rate, albumin, pulse pressure, calf circumference, body surface area, fructosamine, and complement 4. Eight BA models were successfully constructed, namely MLR, PCA, KDM1, KDM2, RF, SVM, XGBoost and lightGBM, which had the worst R2 of 0.45 and the best R2 of 0.92. The best R2 for cross-validation was KDM2 (0.89), followed by PCA (0.62). CONCLUSION In this study, we successfully applied eight methods, including traditional methods and machine learning, to construct models of biological age, and the performance varied among the models.

Abstract
The purpose of this study was to compare the effects of nutritional supplement drinks (NSDs) and nutritional education (NE) on the nutritional status and physical performance of older nursing home residents who were at risk of malnutrition. This study was a clustered, randomized, parallel, multi-center clinical trial, with 107 participants more than 65 years old and at risk of malnutrition recruited from several nursing homes in this study. Participants were divided into two groups: an NE group (n = 50) and an NSD group (n = 57). The NE group was given NE by a dietitian, while the NSD group was provided with two packs of NSD except receiving NE (Mei Balance, Meiji Holdings, Tokyo, Japan) per day as a snack between meals and before bed. Anthropometric data, blood pressure, nutritional status, blood biochemical biomarkers, and physical performance were measured before and after 12-week interventions. After 12 weeks of NE combined with NSD intervention, body weight, body-mass index, the mini nutritional assessment-short form (MNA-SF) score, walking speed, and SF-36 questionnaire score were improved in older nursing home residents at risk of malnutrition.

Abstract
This study assessed the relationship between handgrip strength (HGS) and activities of daily living, balance, walking speed, calf circumference, body muscle, and body composition in elderly patients with thoracolumbar vertebral compression fracture (VCF). A cross-sectional study in a single hospital was performed with elderly patients diagnosed with VCF. After admission, we evaluated HGS, 10-meter walk test (speed), Barthel Index, Berg Balance Scale (BBS), numerical rating scale of body pain, and calf circumference. We examined skeletal muscle mass, skeletal muscle mass index, total body water (TBW), intracellular water, extracellular water (ECW), and phase angle (PhA) in patients with VCF using multi-frequency direct segmental bioelectrical impedance analysis after admission. A total of 112 patients admitted for VCF were enrolled (26 males, 86 females; mean age 83.3 years). The prevalence of sarcopenia according to the 2019 Asian Working Group for Sarcopenia guideline was 61.6%. HGS was significantly correlated with walking speed (P < .001, R = 0.485), Barthel Index (P < .001, R = 0.430), BBS (P < .001, R = 0.511), calf circumference (P < .001, R = 0.491), skeletal muscle mass index (P < .001, R = 0.629), ECW/TBW (P < .001, r = -0.498), and PhA (P < .001, R = 0.550). HGS was more strongly correlated with walking speed, Barthel Index, BBS, ECW/TBW ratio, and PhA in men than women. In patients with thoracolumbar VCF, HGS is associated with walking speed, muscle mass, activities of daily living measured using the Barthel Index, and balance measured using BBS. The findings suggest that HGS is an important indicator of activities of daily living, balance, and whole-body muscle strength. Furthermore, HGS is related to PhA and ECW/TBW.

Associations of Serum Albumin With Disability in Activities of Daily Living, Mobility and Objective Physical Functioning Regardless of Vitamin D: Cross-Sectional Findings From the Chinese Longitudinal Healthy Longevity Survey. Front Nutr 2022; 9:809499. [PMID: 35284431 PMCID: PMC8908380 DOI: 10.3389/fnut.2022.809499] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Accepted: 01/19/2022] [Indexed: 11/17/2022] Open
Abstract
Objective To examine the associations of serum albumin, a nutrition indicator, with disability in activities of daily living (ADL), mobility, and objective physical functioning among Chinese older adults. Materials and Methods Cross-sectional data of 2233 older adults (≥65 years) who participated in the 2011/2012 main survey of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and the 2012 biomarker sub-study was used. Serum albumin was measured by immunoturbidimetric assay. Physical functioning included subjectively (ADL and mobility) and objectively measured disability (standing up from a chair, picking up a book from the floor, and turning around 360°). Multivariable logistic regression models were performed. Results After adjusting for age and sex, compared with participants in the lowest quartile group of serum albumin, those in the highest quartile group had 45% lower odds of disability in ADL (odds ratio [OR]: 0.55; 95% confidence interval [CI]: 0.38, 0.80); 48% lower odds of disability in mobility (OR: 0.52; 95% CI: 0.38, 0.71); 46% lower odds of disability in standing up from a chair (OR: 0.54; 95% CI: 0.34, 0.85); and 37% lower odds of disability in picking up a book from the floor (OR: 0.63; 95% CI: 0.40, 0.97). We did not observe a statistically significant interaction effect between serum albumin and vitamin D on disability in physical functioning. Conclusion Serum albumin level was associated with physical functioning among Chinese older adults, regardless of vitamin D level. The findings indicate that appropriate management of poor nutritional status, in particular low serum albumin levels, may contribute to maintaining physical functioning in older adults.

Abstract
BACKGROUND Objective deterioration in activities of daily living (ADLs) exists among older population, and particularly worsens with age. Considering the criterion standard of positive aging and longevity, little information focusing on centenarians is available. This study set out to explore the relationship between serum albumin and ADLs among centenarians in long-lived areas. METHODS This population-based cross-sectional study investigated a full sample of Chinese centenarians in Hainan, the longest-lived area of China (n = 1002). We assessed serum albumin levels and basic and instrumental activities of daily living (BADLs and IADLs). RESULTS Of 1002 participants included in the analysis, 287 (28.64%) had BADL disabilities and 648 (64.67%) had IADL disabilities. The median level of serum albumin was 38.5 g/L (interquartile range, 36.2-41.3). The multivariable analyses controlling for socio-demographic characteristics, lifestyle, morbidities, and other influential factors showed that albumin level was associated with the total score of BADL (standard β = 0.335, P < 0.001) and IADL (standard β = 0.206, P < 0.001). With the increasing of albumin level, the risk of ADLs disability decreased (BADL: odds ratios [OR] = 0.835, 95% Confidence interval [CI]: 0.797-0.876; IADL: OR = 0.863, 95%CI: 0.824-0.905). In the stratified analyses, similar results were found in both sex, but were more prominent in women. CONCLUSIONS Higher levels of serum albumin was a protective factor for the decline of ADLs in centenarians. This association can be observed in both genders and is more pronounced in women.

Abstract
Patients who become malnourished during hospitalization because of illness or treatment often receive intervention from a nutrition support team (NST). The NST intervention not only enhances the nutritional status but also decreases medical expenses and catheter-related complications. However, the impact of the NST intervention on the home discharge of hospitalized community-dwelling older adults remains unclear. Hence, this study aims to investigate factors related to home discharge in malnourished community-dwelling older adults.In this retrospective longitudinal cohort study, examined 191 community-dwelling older adults aged ≥65 years (108 males; mean age: 80.9 ± 7.8 years) who received the NST intervention. All participants were categorized into two groups based on whether they were home discharged or not (home discharge group and non-home discharge group). We performed intergroup comparisons using serum albumin (Alb) as an index of the nutritional status and functional independence measure (FIM: motor and cognitive items) as an index of activities of daily living (ADL). Furthermore, we constructed a prognostic model of home discharge using the logistic regression analysis.The home discharge group had 94 participants, with a home discharge rate of 50.8%. Baseline body mass index (BMI), motor-FIM score, and cognitive-FIM score were significantly higher in the home discharge group compared with the non-home discharge group (P = .002, P < .001, P < .001, respectively). In the home discharge group, BMI declined significantly, Alb elevated significantly, and both motor-FIM and cognitive-FIM score enhanced significantly by the completion of the NST intervention (P < .001, P < .001, P < .001, P = .005, respectively). The adjusted logistic regression analysis extracted the baseline BMI (odds ratio [OR], 1.146; 95% confidence interval [CI]: 1.034-1.270), baseline motor-FIM score (OR, 1.070; 95% CI: 1.036-1.105), and extent of change in the motor-FIM score (OR, 1.061; 95% CI: 1.026-1.098) as independent factors that predict home discharge.This study highlights the significance of higher baseline BMI, higher baseline ADL level, ADL enhancements, and improvements in the nutritional status by the NST intervention in malnourished community-dwelling older adults considering home discharge.

Abstract
Background Oral health is thought to be associated with diet quality, and socioeconomic status (SES) affects both oral health and diet. The aim of this study was to investigate the association between the number of teeth and dietary intake as well as nutritional biomarker, considering the subjects’ SES. Methods We conducted a cross-sectional analysis of data from 2049 individuals aged ≥ 50 years from the National Integrated Project for Prospective Observation of Non-communicable Disease and its Trends in the Aged 2010. The number of remaining teeth was categorized into age-specific quartiles (Q1 to Q4). We assessed the adjusted means and 95% confidence intervals for dietary variables by the number of teeth using analysis of covariance. Stratified analyses by SES were also conducted. Results The intake of grain products was 31 g higher, and those of vegetables and meat were 30 g and 8 g lower, respectively, in Q1 (fewer teeth) than in Q4 (more teeth). Carbohydrate intake was higher whereas protein, minerals (potassium, magnesium, and zinc), vitamins (vitamins A, E, B1, B6, β-carotene, and folic acid), and dietary fiber intakes were lower among individuals with fewer teeth. Adjusted mean serum albumin levels were low in Q1. The associations between the number of teeth and dietary intake were more evident in individuals with a low SES. Conclusions Having few remaining teeth was associated with a low nutrient intake and low serum albumin levels in middle-aged and older Japanese adults, and these associations were more evident in individuals with low SES.

Abstract
The ethical, logistical, and biological complications of working with an older population of people inherently limits clinical studies of frailty. The recent development of animal models of frailty, and tools for assessing frailty in animal models provides an invaluable opportunity for frailty research. This review summarizes currently published animal models of frailty including the interleukin-10 knock-out mouse, the mouse frailty phenotype assessment tool, and the mouse clinical frailty index. It discusses both current and potential roles of these models in research into mechanisms of frailty, interventions to prevent/delay frailty, and the effect of frailty on outcomes. Finally, this review discusses some of the challenges and opportunities of translating research findings from animals to humans.

Abstract
OBJECTIVES Anemia and malnutrition are risk factors for frailty in older people but data from multicenter studies among German geriatric inpatients are lacking. This analysis evaluated data from the multicenter study "GerAnaemie2013" commissioned by the German Geriatric Society. PATIENTS AND METHODS The study involved an analysis of the 579 geriatric inpatients recruited in the context of the German multicenter study "GeriAnaemie2013". Study parameters: Barthel index (BI), handgrip strength, nutritional data (e.g. loss of appetite, loss of weight and decreased food intake). INCLUSION CRITERIA in-patient age ≥70 years, exclusion criteria: current cancer disease or cancer-associated treatment. Anemia was defined according to the World Health Organization (WHO) criteria. RESULTS The mean age of patients was 81.9 years, overall prevalence of anemia 55.1 %, mean hemoglobin (Hb) level 11.9 g/dl, average BI 50.8 points and 30.3 % of all patients were at risk of malnutrition. While univariate analysis revealed a significantly lower BI in anemic patients, this association was no longer seen in multivariate analysis. Regression analysis revealed that a drug intake of > 5 drugs/day doubles the chance of suffering from anemia with an adjusted odds ratio (OR) of 2.17 (confidence interval (CI) 1.28-3.68, p = 0.004) as well as a serum albumin level below 3.5 g/dl with an adjusted OR of 2.11 (range 1.40-3.19, p < 0.001). CONCLUSION Polymedication and low serum albumin were independent risk factors for anemia in geriatric patients, probably reflecting disease severity.

Abstract
BACKGROUND Low serum albumin levels are associated with aging and medical conditions such as cancer, liver dysfunction, inflammation, and malnutrition and might be an independent predictor of long-term mortality in healthy older populations. We tested the hypothesis that economic status is associated with serum albumin levels and explained by nutritional and health status in Japanese older adults. DESIGN We performed a cross-sectional analysis using data from the Japan Gerontological Evaluation study (JAGES). The study participants were 6528 functionally independent residents (3189 men and 3339 women) aged ≥65 years living in four municipalities in Aichi prefecture. We used household income as an indicator of economic status. Multiple linear regression was used to compare serum albumin levels in relation to household income, which was classified as low, middle, and high. Additionally, mediation by nutritional and health-related factors was analyzed in multivariable models. RESULTS With the middle-income group as reference, participants with low incomes had a significantly lower serum albumin level, even after adjustment for sex, age, residential area, education, marital status, and household structure. The estimated mean difference was -0.17 g/L (95% confidence interval, -0.33 to -0.01 g/L). The relation between serum albumin level and low income became statistically insignificant when "body mass index", "consumption of meat or fish", "self-rated health", "presence of medical conditions", "hyperlipidemia", or "respiratory disease "was included in the model. CONCLUSION Serum albumin levels were lower in Japanese older adults with low economic status. The decrease in albumin levels appears to be mediated by nutrition and health-related factors with low household incomes. Future studies are needed to reveal the existence of other pathways.

Abstract
BACKGROUND The medical care of severe motor and intellectual disabilities (SMID) depends on the empirical medical care. Epileptic seizure specific to SMID is difficult to suppress using anti-epileptic drugs, and its tendency to persist for long periods poses an issue. The present study was undertaken to evaluate the relationship between epileptic seizure in cases with SMID and oxidative stress in the living body by examining endogenous antioxidants, the degree of oxidation (reactive oxygen metabolites (d-ROMs)), and the biological antioxidant potential (BAP) as indicators. METHODS Target patients were 43 SMID epilepsy patients. Blood was sampled before breakfast and medication. As for the specimen, d-ROMs and BAP were measured using the free radical analyzer. RESULTS The present study did not reveal any correlation between endogenous antioxidants (albumin) and the frequency of epileptic seizures. On the other hand, d-ROMs were correlated with the frequency of epileptic seizure. In particular, strong correlations between the frequency of epileptic seizures and the d-ROMs/BAP ratio as well as the BAP/d-ROMs ratio were noted. CONCLUSIONS These results indicate that the use of d-ROMs and BAP as biomarkers can provide a tool for predicting the prognosis of epileptic seizures in patients with SMID.

Abstract
Acetaminophen is a commonly used analgesic that can cause severe hepatotoxicity in overdose. Despite old age and frailty being associated with extensive and long-term utilization of acetaminophen and a high prevalence of adverse drug reactions, there is limited information on the risks of toxicity from acetaminophen in old age and frailty. This study aimed to assess changes in the risk and mechanisms of hepatotoxicity from acute, chronic and sub-acute acetaminophen exposure with old age and frailty in mice. Young and old male C57BL/6 mice were exposed to either acute (300 mg/kg via oral gavage), chronic (100 mg/kg/day in diet for six weeks) or sub-acute (250 mg/kg, t.i.d., for three days) acetaminophen, or saline control. Pre-dosing mice were scored for the mouse clinical frailty index, and after dosing serum and liver tissue were collected for assessment of toxicity and mechanisms. There were no differences with old age or frailty in the degree of hepatotoxicity induced by acute, chronic or subacute acetaminophen exposure as assessed by serum liver enzymes and histology. Age-related changes in the acetaminophen toxicity pathways included increased liver GSH concentrations, increased NQO1 activity and an increased pro- and anti-inflammatory response to acetaminophen in old age. Frailty-related changes included a negative correlation between frailty index and serum protein, albumin and ALP concentrations for some mouse groups. In conclusion, although there were changes in some pathways that would be expected to influence susceptibility to acetaminophen toxicity, there was no overall increase in acetaminophen hepatotoxicity with old age or frailty in mice.

Abstract
This cross-sectional and 4-year longitudinal cohort study aimed to clarify how various lifestyle-related variables affect knee extension strength in elderly Japanese women. The participants were community-dwelling women (n = 575) living in the Itabashi Ward of Tokyo, Japan aged 75-85 years at baseline (in 2008) who returned for a follow-up examination 4 years later (in 2012). Maximum isometric knee extension strength in the dominant leg was measured during comprehensive medical check-ups at baseline and follow-up. Interviews with participants included questions on their history of 11 diseases and lifestyle-related factors such as physical activity as well as dietary, smoking, and drinking habits. Cross-sectional and longitudinal analyses yielded inconsistent results regarding the associations between lifestyle-related factors and knee extension strength. While going out more frequently and regular physical exercise positively affected baseline knee extension strength, they did not affect knee extension strength in the longitudinal analysis. The longitudinal analysis revealed that more frequent intake of soy products or green and yellow vegetables at baseline decreased age-related knee extension strength decline. The inconsistent results from the cross-sectional and longitudinal analyses indicate that conducting both types of analyses is crucial for researching this type of subject. The present study demonstrates that the age-related decline in muscle strength is lower in those who frequently eat soy products or green and yellow vegetables. Thus, recommending higher intake of soy products, and green and yellow vegetables for the elderly might help maintain their muscle health.

Abstract
Albumin is the most abundant plasmatic protein. It is only produced by the liver and the full extent of its metabolic functions is not known in detail. One of the main roles assigned to albumin is as an indicator of malnutrition. There are many factors, in addition to nutrition, that influence levels of albumin in plasma. The main aim of this review is to assess the clinical significance of albumin in elderly people in the community, in hospital and in care homes. Following the review, it can be stated that age is not a cause of hypoalbuminemia. Albumin is a good marker of nutritional status in clinically stable people. Significant loss of muscle mass has been observed in elderly people with low albumin levels. Hypoalbuminemia is a mortality prognostic factor in elderly people, whether they live in the community or they are in hospital or institutionalized. Low levels of albumin are associated to worse recovery following acute pathologies. Inflammatory state and, particularly, high concentrations of IL-6 and TNF-alpha, are two of the main influencing factors of hypoalbuminemia. In elderly patients with a hip fracture, albumin levels below 38 g/L are associated to a higher risk of post-surgery complications, especially infections. Further research is needed on the impact of nutritional intervention upon albumin levels and on the outcomes in elderly people in the community, in hospital and in care.

Abstract
BACKGROUND Several blood biomarkers have been linked to functional disability, a health problem in general populations. However, there are limited data for evaluating the potential association of biomarkers with functional disability in an extremely longevous (95+) population. METHODS We used data from 420 extremely longevous individuals from the Rugao longevity cohort, a population-based association study conducted in Rugao, a longevity town in China. Functional disability was assessed by the Katz Index of Independence in activities of daily living. Blood biomarkers, including serum lipid, lipoprotein cholesterol, serum albumin, and lymphocyte count, were correlated with activities of daily living. RESULTS Among extremely longevous women, following the degree of functional disability, serum albumin and lymphocyte count decreased significantly (all p for trend < .001). In a univariate model, serum albumin (β = -0.279, p < .001), lymphocyte count (β = -0.187, p < .001), and neutrophil count (β = 0.140, p = .012) were found to be significantly associated with activities of daily living in women. After adjustment for other covariates, the significance remained. Notably, multivariate regression analysis revealed independent effects of all the three biomarkers on activities of daily living (β = -0.242, -0.185, and 0.143, all p < .05). We did not observe any association in men. CONCLUSIONS We found significant associations between serum albumin, lymphocyte count, and neutrophil count and physical disability even after adjustment for potential confounders in extremely longevous women, which call for further study. The findings provide preliminary but crucial clues for future studies specifically aimed at exploring the longitudinal relationships of interest before proceeding with interventions.

Abstract
Background We assessed the association between activities of daily living (ADL) and mortality among nursing home residents in Japan. Methods This 1-year prospective cohort study investigated 8902 elderly adults in 140 nursing homes. Baseline measurements included age, sex, height, weight, body mass index (BMI), ADL, and dementia level. ADL levels were obtained by caregivers, using the Barthel Index (BI), after which total BI scores were calculated (higher scores indicate less dependence). Information on dates of discharge and mortality was also obtained to calculate person-years. The Cox proportional hazards model was used to estimate hazard ratios (HRs). Results Mean age was 84.3 years, and mean total BI score was 38.5. The HRs of mortality adjusted for sex, age, BMI, and type of nursing home were 7.6 (95% CI: 3.3–17.8) for those with a BI score of 0 (totally dependent), 3.9 (1.7–9.0) for those with a score of 1 to 10, 3.5 (1.4–8.7) for those with a score of 11 to 40, 2.7 (1.4–5.1) for those with a score of 41 to 70, and 1.3 (0.7–2.4) for those with a score of 71 to 99 (P for trend <0.001), as compared with those with a score of 100. Multivariate analysis revealed that BI, sex, age, and BMI were significantly associated with mortality rate. Conclusions There was a clear inverse association between ADL level and mortality. In conjunction with other risk factors, ADL level might effectively predict short-term mortality in institutionalized elderly adults.
