Effect of multicomponent intervention on malnutrition in older adults: A multicenter randomized clinical trial. Clin Nutr ESPEN 2024; 60:31-40. [PMID: 38479928 DOI: 10.1016/j.clnesp.2024.01.004] [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: 08/15/2023] [Revised: 01/01/2024] [Accepted: 01/04/2024] [Indexed: 04/12/2024]
Abstract
BACKGROUND & AIMS Malnutrition is a significant geriatric syndrome (GS) prevalent in older adults and seriously affects patient prognosis and quality of life. We assessed the impact of the multicomponent intervention of health education, dietary advice, and exercise with oral nutritional supplementation (ONS) on nutritional status, body composition, physical functions, and quality of life. METHODS This multicenter randomized clinical trial (RCT) was performed from April 2021 to April 2022. The intervention lasted for 12 weeks, and 99 older adults with malnutrition or at risk of malnutrition were enrolled in six nursing homes. All participants were randomly assigned to the control (health education plus standard diet plus exercise) or research (health education plus standard diet plus exercise plus ONS) group. The research group consumed ONS (244 kcal, 9.8g protein, and 9.6g fat per time) twice a day between meals. The primary outcomes were changes in the nutritional status and body composition from baseline to 12 weeks. The secondary outcomes were changes in physical function, quality of life and nutritional associated other blood markers. RESULTS For primary outcomes, after 12 weeks, body weight increased similarly in both treatment arms (time × treatment effect, P > 0.05). There were no between-group differences in body mass index (BMI) or mini nutritional assessment tool-short form (MNA-SF) scores (time × treatment effects, P > 0.05). The MNA-SF score from 11.0 (10.5, 12.0) to 13.0 (11.0, 13.0) in the research group and from 11.0 (10.0, 12.0) to 12.0 (11.0, 13.0) in the control group (both P < 0.05). There were no between-group differences in the skeletal muscle mass index (SMI), fat-free mass index (FFMI), appendicular skeletal muscle mass (ASMM), fat mass (FAT), or leg muscle mass (LMM) (time × treatment effects, P > 0.05). Both groups showed similar and highly significant increases in SMI, FFMI, and LMM after (P < 0.05). The research group showed an increase in fat-free mass (FFM) and ASMM and a decrease in the percent of body fat (PBF) and waist circumference (WC) (P < 0.05). For secondary outcomes, There were no between-group differences in grip strength, short physical performance battery (SPPB), 6-min walking distance (6MWD), activities of daily living (ADL), instrumental activities of daily living (IADL), frailty status (FRAIL), mini-mental state examination (MMSE), Tinetti, geriatric depression scale-15 (GDS-15), or 12-item short form survey (SF-12) (time × treatment effects, P > 0.05). Although there was no significant difference, the 6MWD changed differentially between the two treatment arms during the study period in favor of the research group. Although not significant, SF-12 scores improved after 12 weeks in both groups. No between-group differences were observed in prealbumin (PRE), c-reactive protein (CRP), vitamin D (VIT-D), insulin-like growth factor 1 (IGF-1), alanine transaminase (ALT), aspartate aminotransferase (AST), serum creatinine (Scr), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), insulin, and adiponectin levels (time × treatment effects, P > 0.05). Insulin and adiponectin levels were significantly higher in the control group (P < 0.05). CONCLUSION The twelve-week multicomponent intervention improved the nutritional status of older people in China at risk of malnutrition. ONS may enhance the effects of exercise on muscle mass. This clinical trial was registered (https://www. CLINICALTRIALS gov). The trial number is ChiCTR2000040343.

Abstract
Age-related muscle atrophy (sarcopenia), characterized by reduced skeletal muscle mass and muscle strength, is becoming increasingly prevalent worldwide, which is especially true for older people, and can seriously damage health and quality of life in older adults. This study aims to investigate the beneficial effects of 5'-cytimidine monophosphate (CMP) on H2O2-induced muscular atrophy in C2C12 myotubes. C2C12 myotubes were treated with H2O2 in the presence and absence of CMP and the changes in the anti-oxidation, mitochondrial functions, and expression of sarcopenia-related proteins were observed. Immunofluorescence analysis showed that CMP significantly increased the diameter of myotubes. We found that CMP could increase the activity of antioxidant enzymes and improve mitochondrial dysfunction, as well as reduce inflammatory cytokine levels associated with sarcopenia. RNA-seq analysis showed that CMP could relieve insulin resistance and promote protein digestion and absorption. Western blot analysis further confirmed that CMP could promote the activation of the IRS-1/Akt/S6K signaling pathway and decrease the expression of MuRF1 and Atrogin-1, which are important markers of muscle atrophy. The above results suggest that CMP protects myotubes from H2O2-induced atrophy and that its potential mechanism is associated with activating the IRS-1/Akt/S6K pathway to promote protein synthesis by improving mitochondrial dysfunction and insulin resistance. These results indicate that CMP can improve aging-related sarcopenia.

Abstract
Sarcopenia and diabetes are two age-related diseases that are common in the elderly population, and have a serious effect on their general health and quality of life. Sarcopenia refers to the progressive loss of muscle mass, strength and function, whereas diabetes is a chronic disease characterized by elevated blood sugar levels. The comorbidity of sarcopenia and diabetes is particularly concerning, as people with diabetes have a higher risk of developing sarcopenia due to the combination of insulin resistance, chronic inflammation and reduced physical activity. In contrast, sarcopenia destroyed blood sugar control and exacerbated the development of people with diabetes, leading to the occurrence of a variety of complications. Fortunately, there are a number of effective treatment strategies for sarcopenia in people with diabetes. Physical exercise and a balanced diet with enough protein and nutrients have been proved to enhance the muscular quality and strength of this population. Additionally, pharmacological therapies and lifestyle changes can optimize blood sugar control, which can prevent further muscle loss and improve overall health outcomes. This review aims to summarize the pathogenesis and comprehensive treatment strategies of sarcopenia in elderly patients with type 2 diabetes, which help healthcare professionals recognize their intimate connection and provide a new vision for the treatment of diabetes and its complications in this population. Through early identification and comprehensive treatment, it is possible to improve the muscle function and general quality of life of elderly with diabetes and sarcopenia.

Abstract
We recently reported accelerated cognitive decline in Europeans aged > 70 years with low circulating adropin levels. Adropin is a small, secreted peptide that is highly expressed in the human nervous system. Expression profiling indicate relationships between adropin expression in the human brain and pathways that affect dementia risk. Moreover, increased adropin expression or treatment using synthetic adropin improves cognition in mouse models of aging. Here we report that low circulating adropin concentrations associate with poor cognition (worst quintile for a composite score derived from the MMSE and semantic fluency test) in late-middle aged community-dwelling African Americans (OR = 0.775, P < 0.05; age range 45-65 y, n = 352). The binomial logistic regression controlled for sex, age, education, cardiometabolic disease risk indicators, and obesity. Previous studies using cultured cells from the brains of human donors suggest high expression in astrocytes. In snRNA-seq data from the middle temporal gyrus (MTG) of human donors, adropin expression is higher in astrocytes relative to other cell types. Adropin expression in all cell-types declines with advance age, but is not affected by dementia status. In cultured human astrocytes, adropin expression also declines with donor age. Additional analysis indicated positive correlations between adropin and transcriptomic signatures of energy metabolism and protein synthesis that are adversely affected by donor age. Adropin expression is also suppressed by pro-inflammatory factors. Collectively, these data indicate low circulating adropin levels are a potential early risk indicator of cognitive impairment. Declining adropin expression in the brain is a plausible link between aging, neuroinflammation, and risk of cognitive decline.

Abstract
Sarcopenia remains one of the major pathological features of type 2 diabetes (T2D), especially in older individuals. This condition describes gradual loss of muscle mass, strength, and function that reduces the overall vitality and fitness, leading to increased hospitalizations and even fatalities to those affected. Preclinical evidence indicates that dysregulated mitochondrial dynamics, together with impaired activity of the NADPH oxidase system, are the major sources of oxidative stress that drive skeletal muscle damage in T2D. While patients with T2D also display relatively higher levels of circulating inflammatory markers in the serum, including high sensitivity-C-reactive protein, interleukin-6, and tumor necrosis factor-α that are independently linked with the deterioration of muscle function and sarcopenia in T2D. In fact, beyond reporting on the pathological consequences of both oxidative stress and inflammation, the current review highlights the importance of strengthening intracellular antioxidant systems to preserve muscle mass, strength, and function in individuals with T2D.

Frailty in relation to the risk of carotid atherosclerosis and cardiovascular events in Chinese community-dwelling older adults: A five-year prospective cohort study. Exp Gerontol 2023; 180:112266. [PMID: 37536575 DOI: 10.1016/j.exger.2023.112266] [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: 06/07/2023] [Revised: 07/24/2023] [Accepted: 07/31/2023] [Indexed: 08/05/2023]
Abstract
OBJECTIVE To investigate the frailty, as estimated by accumulated health deficits, in association with the symptomatic carotid atherosclerosis and in relation to five-year cardiovascular (CVD) outcomes. METHODS This is a five-year prospective cohort study. Secondary analysis of data from the Beijing Longitudinal Study on Aging. Community-dwelling people aged 55+ years (n = 1257) have been followed between 2009 and 2014, and having carotid ultrasonography examinations with no CVD events at baseline. Frailty was quantified using the deficit accumulation-based frailty index (FI), constructed from 37 health deficits assessed at baseline. The association between the degree of frailty and carotid atherosclerosis was examined using odds ratios (OR) with multivariate logistic regression analyses. Effects of frailty on the probability of five-year cardiovascular events and mortality were evaluated using Cox proportional hazard ratios (HR). The analyses were adjusted for demographics, baseline carotid atherosclerosis status, and CVD risk factors. RESULTS The FI showed characteristic properties and was independently associated with the major carotid atherosclerosis symptoms, including carotid artery intima-media thickening (the most frail vs. the least frail: OR = 4.39: 1.98-7.82), carotid plaque (OR = 3.41: 1.28-6.54), and carotid plaque stability (OR = 1.19, 95 % CI: 1.01-3.59). Compared with the least frail, the most frail individuals were more likely to develop a cardiovascular event in five years, including myocardial infarction (HR = 3.38, 95 % CI = 1.84-6.19), stroke (HR = 1.26, 95 % CI = 1.00-5.87), CVD death (HR = 6.33, 95 % CI = 1.69-11.02), and all-cause death (HR = 5.95, 95 % CI = 2.74-8.95). CONCLUSION Deficit accumulation was closely associated with carotid atherosclerosis risks and strongly predicted five-year CVD events. The frailty index can be used to help identify older adults at high risks of CVD for improved preventive healthcare.

Abstract
Traumatic brain injury (TBI) is a major cause of death and disability in the United States, exacting a debilitating physical, social, and financial strain. Therefore, it is crucial to examine the impact of TBI on medically underserved communities in the U.S. The purpose of the current study was to review the literature on TBI for evidence of racial/ethnic differences in the U.S. Results of the review showed significant racial/ethnic disparities in TBI outcome and several notable differences in other TBI variables. American Indian/Alaska Natives have the highest rate and number of TBI-related deaths compared with all other racial/ethnic groups; Blacks/African Americans are significantly more likely to incur a TBI from violence when compared with Non-Hispanic Whites; and minorities are significantly more likely to have worse functional outcome compared with Non-Hispanic Whites, particularly among measures of community integration. We were unable to identify any studies that looked directly at underlying racial/ethnic biological variations associated with different TBI outcomes. In the absence of studies on racial/ethnic differences in TBI pathobiology, taking an indirect approach, we looked for studies examining racial/ethnic differences in oxidative stress and inflammation outside the scope of TBI as they are known to heavily influence TBI pathobiology. The literature indicates that Blacks/African Americans have greater inflammation and oxidative stress compared with Non-Hispanic Whites. We propose that future studies investigate the possibility of racial/ethnic differences in inflammation and oxidative stress within the context of TBI to determine whether there is any relationship or impact on TBI outcome.

Abstract
Aging-related muscle loss is a hallmark of aging and is the cause of some negative outcomes. An optimized diet and supplements have a positive effect in slowing down the process of muscle loss. D-galactose(d-gal) has been used widely to develop aging model. This study explored the beneficial effects of whey protein peptides (WPPs) on sarcopenia in d-gal-induced aging mice. A total of 72 SPF male C57BL/6N mice were used in this study. Sixty mice were modeled by injected intraperitoneally with d-gal (100 mg/kg body weight for 6 weeks), and the other 12 mice were used as control, and injected with the same amount of normal saline. After 6 weeks, the modeled mice were randomly divided into the model control group, whey protein group (1.5 g/kg*bw), and three WPPs intervention groups (0.3 g/kg*bw, 1.5 g/kg*bw, 3.0 g/kg*bw), according to serum malondialdehyde (MDA) level. The test samples were orally given to mice by daily garaged. During the 30 days intervention period, the model control group, whey protein group, and WPPs group continued receiving intraperitoneal injections of d-gal, whereas the control group continued receiving intraperitoneal injections of normal saline. The results showed that WPPs could significantly improve the grip strength of aged mice. WPPs could significantly increase lean mass of aged mice and increase muscle weight of gastrocnemius and extensor digitorum longus. WPPs could significantly increase the level of insulin-like growth factor-1 (IGF-1) and reduce level of interleukin (IL)-1, IL-6, tumor necrosis factor-alpha (TNF-α) in serum. WPPs could affect the muscle fiber size in d-gal-induced aging mice. Its specific mechanism may be related to the activation of IGF-1/Akt/mTOR protein synthesis signaling pathway and reduction of the level of inflammation. These results indicate that WPPs can improve aging-related sarcopenia. Compared with whey protein, WPPs supplement seems a better form for sarcopenia.

[PMID: 35631191 PMCID: PMC9143134 DOI: 10.3390/nu14102051] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 05/06/2022] [Accepted: 05/10/2022] [Indexed: 02/07/2023] Open
Abstract
Aging-related muscle loss is a hallmark of aging and is the cause of some negative outcomes. An optimized diet and supplements have a positive effect in slowing down the process of muscle loss. This study was designed to evaluate the beneficial effects of walnut oligopeptides (WOPs) on aging-related muscle loss and explore the possible underlying mechanism in Senescence-Accelerated Mouse Prone 8 (SAMP8) Mice. SAMP8 mice were randomly divided into four groups (n = 15/group), including one group which was the SAMP8 age control group and three groups those were WOP intervention groups. Meanwhile, Senescence Accelerated Resistant Mouse 1 (SAMR1) mice (n = 12), which had normal senescence rates, were used as model controls. During the six-month intervention period, the age control and normal control groups were given sterilized water, while the three WOP intervention groups were given WOP solution with low (110 mg/kg·bw), medium (220 mg/kg·bw) and high concentrations (440 mg/kg·bw), respectively. The results showed that WOPs could significantly increase muscle mass and improve physical performance (wire hang and catwalk behavioral tests) in aging mice. Moreover, WOPs could significantly reduce the levels of IL-1β, IL-6 and TNF-α in serum and gastrocnemius tissues and increase the mitochondrial DNA content, as well as the expression levels of AMPK, PGC-1α, NRF-1 and TFAM in the gastrocnemius muscle of aging mice, which was speculated to be the specific mechanism related to mitochondrial function improvement and inflammation reduction. These results indicate that WOPs can improve aging-related muscle loss, in term of both muscle mass and physical performance, and WOP supplements seems to be potentially effective in elderly individuals.

Abstract
Background Maintenance of physical performance is essential for achievement of healthy aging. A few studies have explored the association between inflammatory markers and physical performance in older adults with inconclusive results. Our aim was to analyze the association of tumor necrosis factor-alpha (TNF-α), Interleukin-10 (IL-10), and C-reactive protein (CRP) with physical performance in a sample of older adults in rural settings of Mexico. Methods Our study comprised 307 community-dwelling older men and women who participated in the third wave of the Rural Frailty Study. We assessed the physical performance with the Short Physical Performance Battery (SPPB) and classified older adults as low performance if SPPB scored ≤8. Inflammatory markers were ascertained using serum by immunodetection methods. Logistic regression models were used to estimate the associations between inflammatory markers and physical performance. Results In comparison with the normal physical performance group, low physical performance individuals mainly were female (P < 0.01), older (P < 0.01), more illiterate (P = 0.02), more hypertensive (P < 0.01), fewer smokers (P = 0.02), and had higher CRP levels (P < 0.01). The logistic model results showed a significant association between the 3rd tertile of CRP and low physical performance (OR = 2.23; P = 0.03). IL-10 and TNF-α levels did not show a significant association. Conclusions The results of this study were mixed, with a significant association of physical performance with higher CRP levels but nonsignificant with IL-10 and TNF-α. Further studies with improved designs are needed by incorporating a broader set of inflammatory markers.

Abstract
BACKGROUND The aim of this study was to evaluate the association between systemic non-communicable diseases (NCDs; including lung, kidney, mental and cardiovascular diseases, rheumatoid arthritis, cancer and spinal problems), common risk factors, and tooth loss (TL), as an endpoint of prevalent oral NCDs (periodontitis and caries). METHODS A total of 60,271 noninstitutionalized adults (≥30 years) were evaluated, using data from the 2019 Brazilian National Health Survey. Negative binomial regressions were performed, adjusting for sex, age, ethnicity, educational attainment, oral hygiene, risk factors for periodontitis and caries (diabetes, smoking and a cariogenic diet). The dependent variable was TL expressed as a numerical value. RESULTS Diabetes, current smoking and a frequent cariogenic diet were significantly associated with TL - Incidence Rate Ratio [IRR(95%CI)]: 1.11(1.08-1.14), 1.28(1.25-1.31) and 0.97(0.94-0.99), respectively. Significant associations were observed for TL and all assessed NCDs, except for kidney diseases, cancer and musculoskeletal diseases related to work, with IRR ranging from 1.06 for hypertension and asthma to 1.16 for rheumatoid arthritis. Regular consumption (4-7 days/week) of vegetables, fruits and beef; alcohol up to 8 doses/week; and physical exercise were associated with a lower IRR for TL (p<0.05). Obesity, but not overweight, was associated with increased TL [1.05(1.03-1.07)]. Smoking, hypertension, arthritis, other mental diseases and spinal problems further increased the IRR for TL in individuals with diabetes (p<0.05). CONCLUSION We conclude that certain chronic systemic conditions are associated with TL in Brazilian adults. This is likely due to shared risk factors; however causal associations cannot be examined in this cross-sectional dataset. This article is protected by copyright. All rights reserved.

Abstract
Sarcopenia is an aged-related syndrome that is progressive and can be accelerated by other concomitant disease states. Sarcopenia, characterized by loss of skeletal muscle mass, reduced muscle strength, and/or reduced physical performance, is one of the main reasons for limitation of daily activities in the elderly. It is associated with an increased incidence of many adverse events, such as dysfunction, falls, weakness, hospitalization, disability and even death. Sarcopenia justifies one of the most widely accepted theories that low-grade chronic inflammation associated with aging, known as inflammatory aging, is important to the pathogenesis of many age-related diseases. Currently, the diagnosis of sarcopenia is based on a comprehensive assessment of three aspects: muscle mass, muscle strength and physical performance. The measurement of muscle mass is complicated, as the measurement of muscle strength and gait speed is easily affected by the physical conditions of the subjects. This makes the measurements inaccurate and prospective, and it is difficult to achieve continuous, purposeful monitoring. In addition, serum levels of inflammatory cytokines change as inflammatory states develop in the elderly population. This manuscript focuses on the correlation between serum inflammatory cytokines and sarcopenia in recent years, plus the possible underlying mechanisms.

Abstract
Rationale: The biological mechanisms of long-term cognitive impairment and disability after critical illness are unclear.Objectives: To test the hypothesis that markers of acute inflammation and coagulation are associated with subsequent long-term cognitive impairment and disability.Methods: We obtained plasma samples from adults with respiratory failure or shock on Study Days 1, 3, and 5 and measured concentrations of CRP (C-reactive protein), IFN-γ, IL-1β, IL-6, IL-8, IL-10, IL-12, MMP-9 (matrix metalloproteinase-9), TNF-α (tumor necrosis factor-α), soluble TNF receptor 1, and protein C. At 3 and 12 months after discharge, we assessed global cognition, executive function, and activities of daily living. We analyzed associations between markers and outcomes using multivariable regression, adjusting for age, sex, education, comorbidities, baseline cognition, doses of sedatives and opioids, stroke risk (in cognitive models), and baseline disability scores (in disability models).Measurements and Main Results: We included 548 participants who were a median (interquartile range) of 62 (53-72) years old, 88% of whom were mechanically ventilated, and who had an enrollment Sequential Organ Failure Assessment score of 9 (7-11). After adjusting for covariates, no markers were associated with long-term cognitive function. Two markers, CRP and MMP-9, were associated with greater disability in basic and instrumental activities of daily living at 3 and 12 months. No other markers were consistently associated with disability outcomes.Conclusions: Markers of systemic inflammation and coagulation measured early during critical illness are not associated with long-term cognitive outcomes and demonstrate inconsistent associations with disability outcomes. Future studies that pair longitudinal measurement of inflammation and related pathways throughout the course of critical illness and during recovery with long-term outcomes are needed.

Abstract
Sarcopenia a recognised geriatric syndrome. This study aims to evaluate the prevalence of possible sarcopenia, sarcopenia and severe sarcopenia among older Chinese adults and to identify any associated factors for possible sarcopenia according to the updated diagnostic criteria of the Asian Working Group for Sarcopenia 2019 (AWGS 2019). We used data from the China Health and Retirement Longitudinal Study (CHARLS). The main outcome of this study was possible sarcopenia. Handgrip strength was measured via a dynamometer. The muscle mass was estimated by anthropometric measures. Physical performance was measured by 5-time chair stand test and gait speed test. A multivariate logistic regression model with stepwise method was employed to identify factors associated with possible sarcopenia. A total of 6172 participants aged 60–94 years were included. The prevalence of possible sarcopenia, sarcopenia and severe sarcopenia was 38.5%, 18.6%, and 8.0%, respectively. Age, rural area, falls, higher C-reactive protein (CRP), and chronic diseases (including hypertension, chronic lung diseases, heart disease, psychiatric disease and arthritis) were associated with a higher risk of possible sarcopenia. Conversely, alcohol consumption, higher gait speed and high levels of hemoglobin were associated with decreased risk of possible sarcopenia. However, the associations between possible sarcopenia with alcohol consumption, heart disease, psychiatric disease and hemoglobin were not significant after Bonferroni correction. Our study reported a relatively high prevalence of sarcopenia among older Chinese population, and identified a range of factors associated with sarcopenia. We also found rural elders are more vulnerable to sarcopenia than urban elders. Additionally, we discovered systemic inflammation might be one of the contributing factors between sarcopenia and related comorbidities. We believe the findings of this study would help to identify individuals at high risk of sarcopenia early and therefore implement the prevention and treatment strategies to reduce the disease burden in China.

Abstract
Tooth loss is a prevailing condition in China due to the high prevalence of oral diseases. Since previous studies explored the association between tooth loss and handgrip strength showed incongruous results, the aim of this study was to investigate the association between tooth loss and handgrip strength in Tianjin, China. Cross-sectional data in the present study used baseline data of Tianjin Chronic Low-grade Systemic Inflammation and Health (TCLSIH) Cohort Study during 2013–2016. Eligible adults (n = 26275) were classified into four groups depending on the number of missing teeth (excluding third molars): 0, 1–2, 3–5 and ≥6. Handgrip strength was measured using a handheld type dynamometer. Analysis of covariance was used to examine the relationships between tooth loss and handgrip strength and handgrip strength per body weight according to gender. After adjustment for potential confounders, the relationships existed between increasing categories of tooth loss and handgrip strength, as well as handgrip strength per weight. The data of stratified analysis showed that there was a trending association between decreased handgrip strength and fewer retained teeth both in males and females less than 60 years of age (P for trend <0.01); whereas no significant association 60 years of age or older. Moreover, loss of more than 3 teeth was significantly associated with reduced muscle strength (P <0.01). Tooth loss is independently associated with handgrip strength in Chinese adults less than 60 years of age.

Circulating factors associated with sarcopenia during ageing and after intensive lifestyle intervention. J Cachexia Sarcopenia Muscle 2019; 10:586-600.

Abstract
BACKGROUND Ageing, chronic diseases, prolonged inactivity, and inadequate nutrition pose a severe threat to skeletal muscle health and function. To date, experimental evidence suggests that ageing-related subclinical inflammation could be an important causative factor in sarcopenia. Although inflammatory signalling has been implicated in the pathogenesis of experimental animal models of sarcopenia, few studies have surveyed the clinical association between circulating factors and muscle mass in patients before and after lifestyle interventions. In this study, we evaluated whether proinflammatory cytokines are associated with the onset of sarcopenia, which circulating factors are associated with the severity of sarcopenia, and how these factors change after lifestyle interventions in sarcopenic elderly persons. METHODS A total of 56 elderly subjects (age ≥ 60 years) with sarcopenia and 56 elderly non-sarcopenic subjects, who met entry criteria and had given informed consent, were selected from the Peking Union Medical College Hospital multicentre prospective longitudinal sarcopenia study for testing relevant circulating factors. Thirty-two elderly subjects from the sarcopenic cohort completed a 12 week intensive lifestyle intervention programme with whey supplements (30 g/day) and a personalized resistance training regimen. The levels of proinflammatory cytokines and metabolic hormones, pre-intensive and post-intensive lifestyle interventions, were measured. RESULTS The sarcopenic group was significantly older (72.05 ± 6.54 years; P < 0.001), more likely to be inactive and female (57.1% of all sarcopenic patients), and had a higher prevalence of type 2 diabetes (16% higher risk). Compared with non-sarcopenic subjects, serum interleukin (IL)-6, IL-18, tumour necrosis factor-α (TNF-α), TNF-like weak inducer of apoptosis (TWEAK), and leptin were significantly higher, while insulin growth factor 1, insulin, and adiponectin were significantly lower in sarcopenic patients (all P < 0.05). Logistic regression analyses revealed that high levels of TNF-α (>11.15 pg/mL) and TWEAK (>1276.48 pg/mL) were associated with a 7.6-fold and 14.3-fold increased risk of sarcopenia, respectively. After adjustment for confounding variables, high levels of TWEAK were still associated with a 13.4-fold increased risk of sarcopenia. Intensive lifestyle interventions led to significant improvements in sarcopenic patients' muscle mass and serum profiles of TWEAK, TNF-α, IL-18, insulin, and adiponectin (all P < 0.05). CONCLUSIONS High levels of the inflammatory cytokines TWEAK and TNF-α are associated with an increased risk of sarcopenia, while the metabolic hormones insulin growth factor 1, insulin, and adiponectin are associated with a decreased risk of sarcopenia in our Chinese patient cohort. Intensive lifestyle interventions could significantly improve muscle mass, reduce inflammation, and restore metabolic hormone levels in sarcopenic patients. This trial was registered at clinicaltrials.gov as NCT02873676.

Abstract
Sarcopenia is a loss of muscle mass and function in the elderly that reduces mobility, diminishes quality of life, and can lead to fall-related injuries, which require costly hospitalization and extended rehabilitation. This review focuses on the aging-related structural changes and mechanisms at cellular and subcellular levels underlying changes in the individual motor unit: specifically, the perikaryon of the α-motoneuron, its neuromuscular junction(s), and the muscle fibers that it innervates. Loss of muscle mass with aging, which is largely due to the progressive loss of motoneurons, is associated with reduced muscle fiber number and size. Muscle function progressively declines because motoneuron loss is not adequately compensated by reinnervation of muscle fibers by the remaining motoneurons. At the intracellular level, key factors are qualitative changes in posttranslational modifications of muscle proteins and the loss of coordinated control between contractile, mitochondrial, and sarcoplasmic reticulum protein expression. Quantitative and qualitative changes in skeletal muscle during the process of aging also have been implicated in the pathogenesis of acquired and hereditary neuromuscular disorders. In experimental models, specific intervention strategies have shown encouraging results on limiting deterioration of motor unit structure and function under conditions of impaired innervation. Translated to the clinic, if these or similar interventions, by saving muscle and improving mobility, could help alleviate sarcopenia in the elderly, there would be both great humanitarian benefits and large cost savings for health care systems.

Abstract
BACKGROUND Few studies have explored the factors that are associated with frailty among older people. OBJECTIVE To investigate the frailty status and examine the sociodemographic factors that are associated with of older peoples' frailty status in China. DESIGN Cross-sectional study. METHODS We used convenience sampling to recruit the participants (aged 60 and above) from four communities in an urban area of Wuhu, Anhui, China. Participants completed a questionnaire which included the Edmonton Frail Scale (EFS) and sociodemographic factorsWe used convenience sampling to recruit the participants (aged 60 and above) from four communities in an urban area of Wuhu, Anhui, China. Participants completed a questionnaire which included the Edmonton Frail Scale (EFS) and sociodemographic factors. RESULTS Of 306 participants, the percentage of participants with a robust score (0-4) on the EFS was 71.9%, 14.1% had an apparently vulnerable score (5-6), and 14.0% had a frail score (7-17). Age, chronic disease status and marital status were significantly associated with frailty. CONCLUSIONS There are a high percentage of frail older Chinese adults in the urban area. The present study findings could provide better understanding of the factors associated with frailty status of this population.

Abstract
OBJECTIVES To determine whether combinations of inflammatory markers are related to physical function. DESIGN AND SUBJECTS secondary analysis of baseline of three observational studies of community-dwelling older adults MEASUREMENTS: The baseline data from 3 cohorts of older adults with different health and disease status were employed. Twenty markers of inflammation and metabolism were individually assessed for correlation with usual gait speed and were separated into robust and impairment quartiles. For the robustness and impairment indices, individual markers were selected using step-wise regression over bootstrapping iterations, and regression coefficients were estimated for the markers individually and collectively as an additive score. RESULTS We developed a robustness index involving 6 markers and an impairment index involving 8 markers corresponding positively and negatively with gait speed. Two markers, glycine and tumor necrosis factor receptor 1 (TNFR1), appeared only in the robustness index, and TNFR2; regulated on activation, normal T-cell expressed and secreted; the amino acid factor; and matrix metallopeptidase 3; appeared only in the impairment index. CONCLUSION Indices of biomarkers were associated with robust and impaired physical performance but differ, in composition suggesting potential biological differences that may contribute to robustness and impairment.

Abstract
Venous thromboembolism (VTE) is a common and potentially life-threatening condition which includes both deep-vein thrombosis (DVT) and pulmonary embolism (PE). VTE has a significant clinical and epidemiological impact in the elderly, and its incidence increases to more than 1% per year in older patients, suggesting the presence of specific age-related risk factors in this population. Immobilization seems to predominate as the main cause in patients admitted for medical acute illness in medicine wards, and there is evidence of a high risk in older patients with immobilization resulting from advanced forms of Parkinson’s disease (PD), regardless of the presence of an acute medical condition. In this review, we would to discuss the recent evidence on clinical, molecular and epidemiological features of VTE in older frail subjects focusing on patients with PD and parkinsonism. We also discuss some therapeutic issues about the risk prevention and we suggest a thorough comprehensive geriatric assessment that can represent an optimal strategy to identify and prevent the VTE risk in these patients.

Abstract
The decline in basic and instrumental activities of daily living (BADLs and IADLs, respectively) is a well-established clinical hallmark of dementia. Growing evidence has shown that systemic subclinical inflammation may be related to functional impairment. We evaluated the possible association between low-grade systemic inflammation and functional disability in older individuals affected by dementia. We explored the association between high-sensitivity C-reactive protein (hs-CRP) levels and BADLs/IADLs in older individuals affected by late onset Alzheimer's disease (LOAD; n 110), "mixed" dementia (n 135), or mild cognitive impairment (MCI; n 258), and compared them with 75 normal Controls. Independent of age, gender, comorbidity, and other potential confounders, higher hs-CRP was significantly associated with poorer BADLs (loss ≥ 1 function) in people with LOAD (odds ratio [OR] 3.14, 95% confidence interval [CI], 1.33-7.33) and mixed dementia (OR 2.48, 95%CI 1.12-5.55), but not in those with MCI (OR 1.38, 95%CI 0.83-2.45) or Controls (OR 2.98, 95%CI 0.54-10.10). No association emerged between hs-CRP and IADLs in any of the sub-group. Our data suggest that systemic low-grade inflammation may contribute to functional disability in older patients with dementia.

Abstract
We hypothesized that tumor necrosis factor receptor 1 (TNFR1) levels are associated with long-term trajectories of functional status independently of vascular risk factors and the occurrence of stroke and myocardial infarction (MI) during follow-up. In the Northern Manhattan Study, stroke-free persons aged ≥40 years in northern Manhattan (New York, New York) had annual assessments with the Barthel index (BI) for a median of 13 years (1993-2015). Assessment of baseline demographic factors, risk factors, and laboratory studies included measurement of TNFR1 (n = 1,863). Generalized estimating equations models were used to estimate standardized associations between TNFR1 and 1) baseline functional status and 2) change in function over time, adjusting for demographic factors, vascular risk factors, social variables, cognition, and depression, as well as stroke and MI occurrence during follow-up. The mean age of participants was 70 (standard deviation (SD), 10) years; 66% were women, and 55% were Hispanic. The mean TNFR1 level was 2.57 mg/L. TNFR1 was associated with baseline BI (-0.93 BI points per SD increment in TNFR1; 95% confidence interval: -1.59, -0.26) and change over time (-0.36 BI points per year per SD increment in TNFR1; 95% confidence interval: -0.69, -0.03). In this large population-based study, higher TNFR1 levels were associated with greater baseline disability and disability over time, even with adjustment for baseline covariates and stroke and MI occurrence during follow-up.

Abstract
Pain is common in older adults, is frequently experienced as stressful, and is associated with increased morbidity and mortality. Stress regulatory systems are adaptive to challenge and change, allostasis, until demands exceed the adaptive capacity contributing to dysregulation, resulting in a high allostatic load. A high allostatic load is associated with increased risk of morbidity and mortality. Pain severity, based on the average intensity of frequent pain, was hypothesized to be positively associated with AL. Four formulations of AL were investigated. Cross-sectional data from Wave 4 (2008-2009) of the English Longitudinal Study of Aging (ELSA) were analyzed. Covariates in the model included age, sex, education, smoking status, alcohol consumption, activity level, depression and common comorbid health conditions. A total of 5341 individuals were included; mean age 65.3(±9.2) years, 55% female, 62.4% infrequent or no pain, 12.6% mild pain, 19.1% moderate pain, and 5.9% severe pain. Severe pain was associated with greater AL defined by all four formulations. The amount of variance explained by pain severity and the covariates was highest when allostatic load was defined by the high risk quartile (12.9%) and by the clinical value (11.7%). Findings indicate a positive relationship between pain severity and AL. Further investigation is needed to determine if there is a specific AL signature for pain that differs from other health conditions.

Abstract
Background Reduced muscular strength in the old age is strongly related to activity impairment and mortality. However, studies evaluating the gender-specific association between muscularity and mortality among older adults are lacking. Thus, the objective of the present study was to examine gender differences in the association between muscular strength and mortality in a prospective population-based cohort study. Methods Data used in this study derived from the Cooperative Health Research in the Region of Augsburg (KORA)-Age Study. The present analysis includes 1,066 individuals (mean age 76 ± 11 SD years) followed up over 3 years. Handgrip strength was measured using the Jamar Dynamometer. A Cox proportional hazard model was used to determine adjusted hazard ratios of mortality with 95% confidence intervals (95% CI) for handgrip strength. Potential confounders (i.e. age, nutritional status, number of prescribed drugs, diseases and level of physical activity) were pre-selected according to evidence-based information. Results During the follow-up period, 56 men (11%) and 39 women (7%) died. Age-adjusted mortality rates per 1,000 person years (95% CI) were 77 (59–106), 24 (13–41) and 14 (7–30) for men and 57 (39–81), 14 (7–27) and 1 (0–19) for women for the first, second and third sex-specific tertile of muscular strength, respectively. Low handgrip strength was significantly associated with all-cause mortality among older men and women from the general population after controlling for significant confounders. Hazard ratios (95% CI) comparing the first and second tertile to the third tertle were 3.33 (1.53–7.22) and 1.42 (0.61-3.28), respectively. Respective hazard ratios (95% CI) for mortality were higher in women than in men ((5.23 (0.67–40.91) and 2.17 (0.27–17.68) versus 2.36 (0.97–5.75) and 0.97 (0.36–2.57)). Conclusions Grip strength is inversely associated with mortality risk in older adults, and this association is independent of age, nutritional status, number of prescribed drugs, number of chronic diseases and level of physical activity. The association between muscular strength and all-cause mortality tended to be stronger in women. It seems to be particularly important for the weakest to enhance their levels of muscular strength in order to reduce the risk of dying early.

Abstract
Frailty is a biologic syndrome reflecting a state of decreased physiological reserve of increasing importance in cardiovascular disease given the aging of the population. The relation between frailty and indexes of cardiac structure and function remains unclear, particularly in the "oldest old." The objective of this study was to examine the association between cardiac function and frailty in an age-homogenous, community-dwelling population of subjects aged 85 and 86 years. Subjects were recruited at ages 85 to 86 from the Jerusalem Longitudinal Cohort Study that has followed an age-homogenous cohort of Jerusalem residents. Subjects underwent echocardiography at their place of residence with standard assessment of cardiac structure and function. Frailty was defined according to the "phenotype of frailty" including at least 3 of the following: weakness, slowness, low physical activity level, exhaustion, and weight loss; 405 subjects (193 men and 212 women) were enrolled in the study. Subjects defined as frail had significantly lower ejection fraction compared with the non-frail group (53.7 ± 0.09% vs 56.4 ± 0.09%; p <0.04). In addition, frail subjects had increased LV mass index (130.6 ± 36.2 g/m(2) vs 119.2 ± 31.1 g/m(2); p <0.03) and LA volume index (41.9 ± 14.7 cm(3)/m(2) vs 36.7 ± 13.1 cm(3)/m(2); p <0.001). Indexes of diastolic function (E/e)' were not significantly different in the 2 groups (11.5 vs 11.8; p = NS). In this age-homogenous cohort of the oldest old, structural changes and indexes of systolic but not diastolic function were associated with frailty.

Abstract
BACKGROUND Older adult frail diabetics have high mortality risk, but data are limited regarding frail late middle-aged diabetics, especially for African-Americans. The aim of this study is to examine the association of diabetes with health outcomes and frailty in the African American Health (AAH) study. METHODS AAH is a population-based longitudinal cohort study. Participants were African Americans (N=998) ages 49 to 65 years at baseline. Cross-sectional comparisons for diabetes included disability, function, physical performance, cytokines, and frailty. Frailty measures included the International Academy of Nutrition and Aging [FRAIL] frailty scale, Study of Osteoporotic Fractures [SOF] frailty scale, Cardiovascular Health Study [CHS] frailty scale, and Frailty Index [FI]). Longitudinal associations for diabetes included new ADLs ≥ 1 and mortality at 9-year follow-up. RESULTS Diabetics were more likely to be frail using any of the 4 frailty scales than were non-diabetics. Frail diabetics, compared to nonfrail diabetics, reported significantly increased falls in last 1 year, higher IADLs and higher LBFLs. They demonstrated worse performance on the SPPB, one-leg stand, and grip strength; and higher Tumor Necrosis Factor receptors (sTNFR1 and sTNFR2). Mortality and 1 or more new ADLs also were increased among frail compared to nonfrail diabetics when followed for 9 years. CONCLUSIONS Frailty in middle-aged African American persons with diabetes is associated with having more disability and functional limitations, worse physical performance, and higher cytokines (sTNFR1 and sTNFR2 only). Middle-aged African Americans with diabetes have an increased risk of mortality and frail diabetics have an even higher risk of death, compared to nonfrail diabetics.

Abstract
BACKGROUND Chili consumption may have a beneficial effect on muscle strength in the general population. The aim of this study was to investigate the relationship between frequency of chili consumption and handgrip strength in adults. DESIGN Population-based cross-sectional study. SETTING This study used baseline data from the Tianjin Chronic Low-grade Systemic Inflammation and Health Cohort Study. PARTICIPANTS A total of 3 717 subjects were recruited to the study. Frequency of chili consumption during the previous month was assessed using a valid self-administered food frequency questionnaire. Analysis of covariance was used to examine the relationship between muscle strength and frequency of chili consumption. Handgrip strength was measured using a handheld digital dynamometer. RESULTS After adjustment for potential confounding factors, significant relationships were observed between different categories of chili consumption and handgrip strength in males, the means (95% confidence interval) for handgrip strength across chili consumption categories were 44.7 (42.1, 47.2) for < one time/week; 45.5 (42.9, 48.1) for one time/week; and 45.8 (43.3, 48.4) for ≥ 2-3 times/week (P for trend < 0.01). Similar results were not observed with sweet pepper consumption. CONCLUSIONS This study reveals a positive correlation between frequency of chili consumption and muscle strength in adult males. Further studies are necessary in order to determine whether there is a causal relationship between chili consumption frequency and muscle strength.

Abstract
Background Previous studies have found inflammation, growth factors, and androgen signaling pathways all contribute to sarcopenia. However, few studies simultaneously have investigated the association between these potential risk factors and sarcopenia among older people. The aim of the study was to investigate whether elevated levels of inflammatory cytokines combined with low levels of anabolic hormone have a synergy effect on muscle strength and functional decline in older people. Methods We designed a cross-sectional study of 1,131 subjects aged 60 years and older. Concentrations of serum C-reactive protein, insulin-like growth factor 1 and dehydroepiandrosteronesulphate were assessed using chemiluminescent immunoassays. Handgrip strength was measured using a dynamometer, and physical performance was assessed using a four-meter gait speed and Timed Up and Go test. We defined poor physical performance as a 4-m gait speed <0.8 m/s or Timed Up and Go test ≥13.5 s. Results After adjustment for potential confounding factors, in multiple linear regression analysis, C-reactive protein levels are inversely related to handgrip strength (P <0.01), and in multiple logistic regression analysis, C-reactive protein levels are inversely related to poor physical performance (P for trend <0.05) in males, but not in females. After combining three biomarkers, no significant results were observed between biomarker scores and muscle strength or physical performance. Conclusions In older males, higher serum C-reactive protein levels, but not insulin-like growth factor 1 and dehydroepiandrosteronesulphate levels, are independently related to lower muscle strength and poor physical performance. In this study we did not observe that a combination of higher catabolic biomarkers and lower anabolic biomarkers were better predictors for muscle strength and physical performance.

Abstract
Background HIV-infected patients could exhibit accelerated ageing, since age-associated complications like sarcopenia; increased inflammation; lipodystrophy with loss of subcutaneous adipose tissue and/or gain of visceral adipose tissue (VAT); and cardiovascular disease occur at an earlier age. Inflammation is involved in age-associated complications. However, it is not understood whether it is the same inflammatory changes that are involved in the various ageing-associated complications. Our objective was to study whether leptin, interleukin 6 (IL-6), and soluble urokinase plasminogen activator receptor (suPAR) were associated distinctively with adiposity, lipodystrophy and sarcopenia, in HIV-infected patients and healthy Controls. Results Systemic leptin levels were significantly higher in patients with lipodystrophy than without, whereas there was no difference in IL-6 or suPAR levels. Leptin was significantly positively associated with fat mass index (FMI) and abdominal VAT, but not with lean mass index (LMI). IL-6 was significantly associated with both FMI and VAT, and low LMI. High suPAR was associated with low LMI, and weakly with high FMI and VAT. Conclusions Leptin reflected adiposity- and lipodystrophy-related inflammation, but not sarcopenia. IL-6 reflected both adiposity-, but also sarcopenia-related inflammation; and suPAR was a marker of sarcopenia-related inflammation. Our results indicate that different inflammatory processes can be active simultaneously contributing to the systemic low grade inflammatory state. Identifying major contributors to circulating leptin, IL-6, and suPAR levels could levels could therefore improve our understanding of which inflammatory processes are involved in the various age-related complications.

Abstract
Ageing impairs the muscle anabolic effect of food intake, which may explain muscle loss and an increased risk of sarcopenia. Ageing is also associated with low grade inflammation (LGI), which has been negatively correlated with muscle mass and strength. In rodents, the muscle anabolic resistance observed during ageing and sarcopenia has been ascribed to the development of the LGI. We aimed to investigate this relationship in humans. We studied protein metabolism and physical fitness in healthy elderly volunteers with slight chronic C-reactive protein. Two groups of healthy elderly volunteers were selected on the presence (or not) of a chronic, slight, elevation of CRP (Control: <1; CRP+: >2 mg l(-1) and <10 mg l(-1) , for 2 months). Body composition, short performance battery test, aerobic fitness and muscle strength were assessed. Whole body and muscle protein metabolism and the splanchnic extraction of amino acids were assessed using [(13) C]leucine and [(2) H]leucine infusion. The anabolic effect of food intake was measured by studying the volunteers both at the post-absorptive and post-prandial states. Slight chronic CRP elevation resulted in neither an alteration of whole body, nor skeletal muscle protein metabolism at both the post-absorptive and the post-prandial states. However, CRP+ presented a reduction of physical fitness, increased abdominal fat mass and post-prandial insulin resistance. Plasma cytokines (interleukin-1, interleukin-6, tumour necrosis factor α) and markers of endothelial inflammation (intercellular adhesion molecule, vascular cell adhesion molecule, selectins) were similar between groups. An isolated elevated CRP in healthy older population does not indicate an impaired skeletal muscle anabolism after food intake, nor an increased risk of skeletal muscle wasting. We propose that a broader picture of LGI (notably with elevated pro-inflammatory cytokines) is required to impact muscle metabolism and mass. However, an isolated chronic CRP elevation could predict a decrease in aerobic fitness and insulin resistance installation in elderly individuals.

Abstract
BACKGROUND Recently, a great deal of attention has been paid to the role of inflammatory processes in the pathophysiology of sarcopenia. The aim of the present study was to examine the relationship between NSAID use and sarcopenia in a large sample of community-dwelling elderly people aged 80 years or older. METHODS Data are from the baseline evaluation of 354 individuals enrolled in the ilSIRENTE Study. Following the recommendations of the European Working Group on Sarcopenia in Older People (EWGSOP), the diagnosis of sarcopenia was established on the basis of low muscle mass plus either low muscle strength or low physical performance. The relationship between NSAID use and sarcopenia was estimated by deriving odds ratios (ORs) from multiple logistic regression models considering sarcopenia as the dependent variable. RESULTS Nearly 12% (n = 44) of the study sample used NSAIDs. Using the EWGSOP-suggested algorithm, 103 individuals (29.1%) with sarcopenia were identified. Ninety-nine (31.9%) participants were affected by sarcopenia among non-NSAID users compared with 4 participants (9.1%) among NSAID users (P < .001). Compared with all nonusers, NSAID users had a nearly 80% lower risk of being affected by sarcopenia (OR 0.21, 95% CI 0.07-0.61). After adjusting for potential confounders, NSAID users had a lower risk of sarcopenia compared with nonusers (OR 0.26, 95% CI: 0.08-0.81). CONCLUSIONS The results are consistent with the hypothesis that long-term NSAID use might have a protective effect against the loss of muscle mass and function. Interventions able to reduce inflammation-related adverse outcomes at muscle level may be warranted.

Abstract
Frailty is now a definable clinical syndrome with a simple screening test. Age-related changes in hormones play a major role in the development of frailty by reducing muscle mass and strength (sarcopenia). Selective Androgen Receptor Molecules and ghrelin agonists are being developed to treat sarcopenia. The role of Activin Type IIB soluble receptors and Follistatin-like 3 mimetics is less certain because of side effects. Exercise (resistance and aerobic), vitamin D and protein supplementation, and reduction of polypharmacy are keys to the treatment of frailty.

Abstract
OBJECTIVE To validate the FRAIL scale. DESIGN Longitudinal study. SETTING Community. PARTICIPANTS Representative sample of African Americans age 49 to 65 years at onset of study. MEASUREMENTS The 5-item FRAIL scale (fatigue, resistance, ambulation, illnesses, and loss of weight), at baseline and activities of daily living (ADLs), instrumental activities of daily living (IADLs), mortality, short physical performance battery (SPPB), gait speed, one-leg stand, grip strength and injurious falls at baseline and 9 years. Blood tests for CRP, SIL6R, STNFR1, STNFR2 and 25 (OH) vitamin D at baseline. RESULTS Cross-sectionally the FRAIL scale correlated significantly with IADL difficulties, SPPB, grip strength and one-leg stand among participants with no baseline ADL difficulties (N=703) and those outcomes plus gait speed in those with no baseline ADL dependencies (N=883). TNFR1 was increased in pre-frail and frail subjects and CRP in some subgroups. Longitudinally (N=423 with no baseline ADL difficulties or N=528 with no baseline ADL dependencies), and adjusted for the baseline value for each outcome, being pre-frail at baseline significantly predicted future ADL difficulties, worse one-leg stand scores, and mortality in both groups, plus IADL difficulties in the dependence-excluded group. Being frail at baseline significantly predicted future ADL difficulties, IADL difficulties, and mortality in both groups, plus worse SPPB in the dependence-excluded group. CONCLUSION This study has validated the FRAIL scale in a late middle-aged African American population. This simple 5-question scale is an excellent screening test for clinicians to identify frail persons at risk of developing disability as well as decline in health functioning and mortality.

Abstract
In the present investigation we have analyzed the association between functional dependence and inflammatory biomarkers using the Barthel Index (BI) and the Katz Index (KI). This analysis may contribute to translational medicine by incorporating the clinical and laboratory data to better understand the relationship between chronic inflammation and functional dependence in the elderly population. The ultimate goal of this study was to identify possible useful biomarkers of functional dependence in the elderly. Participants in this study consisted of 120 older subjects (90 women and 30 men; range 68-105 years) who were selected from the Santa Teresa nursing home (Oviedo, Spain). We studied functional status using the following tools to diagnose the functional dependence by clinicians: BI and KI for activities of daily living. We analyzed morbidity, sociodemographic characteristics and a panel of inflammatory and inflammatory-related markers. In linear regression models adjusted by age, sex, anti-inflammatory drug use and morbid conditions high levels of interleukin 6 (IL-6) and soluble TNF receptor-I (sTNF-RI) were associated with functional dependence as measured using BI and KI. Elevated levels of red blood cell distribution width (RDW) were also associated with functional dependence measured using the KI after adjusting for the same potential confounders. The current results suggest that high IL-6, sTNF-RI and RDW levels are associated with the functional dependence in the elderly population. The results are consistent with the presumed underlying biological mechanism, in which the up-regulation of inflammatory mediators is associated with functional dependence in elderly subjects.

Abstract
PURPOSE OF REVIEW Age-related chronic low-grade inflammatory profile (CLIP) has been recognized as an important causative factor for sarcopenia. Here, we report the recent evidence concerning CLIP and sarcopenia. RECENT FINDINGS Twenty-one studies were included (12 observational, five interventional studies and four randomized controlled trials). Observational studies strengthen the association between CLIP and sarcopenia in cross-sectional and longitudinal designs. Interleukin (IL)-6 and tumour necrosis factor-α are the most reported inflammatory parameters. Biopsy studies confirm the role of oxidative mechanisms, protein kinase B and nuclear factor kappa-light-chain-enhancer of activated B cells pathways and implicate stress response mechanisms and heat shock protein. Adipose tissue as source of inflammatory cytokines remains unclear and correction for fat mass is advisable in new research. Exercise interventions (both aerobic and resistance training) demonstrate beneficial effects on CLIP even in the absence of decreases in weight, BMI or fat mass. IL-6 is also released during exercise, in hormone-like fashion unrelated to inflammation, and exercise-induced IL-6 changes require careful interpretation. Soy supplementation in one study showed no influence on CLIP and no recent pharmacological trials were retrieved. SUMMARY Associations between CLIP and sarcopenia are observed quite consistently and underlying mechanisms become apparent. Exercise remains the mainstay intervention to lower CLIP and counter sarcopenia. More research is warranted to unravel the exact dose-response relationship.

Abstract
African Americans (AA) tend to have heightened systemic inflammation and endothelial dysfunction. Endothelial microparticles (EMP) are released from activated/apoptotic endothelial cells (EC) when stimulated by inflammation. The purpose of our study was to assess EMP responses to inflammatory cytokine (TNF-α) and antioxidant (superoxide dismutase, SOD) conditions in human umbilical vein ECs (HUVECs) obtained from AA and Caucasians. EMPs were measured under four conditions: control (basal), TNF-α, SOD, and TNF-α + SOD. Culture supernatant was collected for EMP analysis by flow cytometry and IL-6 assay by ELISA. IL-6 protein expression was assessed by Western blot. AA HUVECs had greater EMP levels under the TNF-α condition compared to the Caucasian HUVECs (6.8 ± 1.1 vs 4.7% ± 0.4%, P = 0.04). The EMP level increased by 89% from basal levels in the AA HUVECs under the TNF-α condition (P = 0.01) compared to an 8% increase in the Caucasian HUVECs (P = 0.70). Compared to the EMP level under the TNF-α condition, the EMP level in the AA HUVECs was lower under the SOD only condition (2.9% ± 0.3%, P = 0.005) and under the TNF-α + SOD condition (2.1% ± 0.4%, P = 0.001). Basal IL-6 concentrations were 56.1 ± 8.8 pg/mL/μg in the AA and 30.9 ± 14.9 pg/mL/μg in the Caucasian HUVECs (P = 0.17), while basal IL-6 protein expression was significantly greater (P < 0.05) in the AA HUVECs. These preliminary observational results suggest that AA HUVECs may be more susceptible to the injurious effects of the proinflammatory cytokine, TNF-α.

Abstract
Weight loss is common in older people. It is associated with increased morbidity and mortality, particularly when unintentional, excessive (>5% body weight), or associated with low body weight (body mass index <22 kg/m(2)). It is often unrecognized, the associated adverse effects not appreciated, and underlying causes not addressed. Intentional weight loss by overweight older people is probably appropriate only when functional problems have resulted from the excess weight. It is important to include, wherever possible, exercise in weight-loss measures to preserve skeletal muscle mass.

Abstract
BACKGROUND Identification of gene variants that contribute to exceptional survival may provide critical biologic information that informs optimal health across the life span. METHODS As part of phenotype development efforts for the Long Life Family Study, endophenotypes that represent exceptional survival were identified and heritability estimates were calculated. Principal components (PCs) analysis was carried out using 28 physiologic measurements from five trait domains (cardiovascular, cognition, physical function, pulmonary, and metabolic). RESULTS The five most dominant PCs accounted for 50% of underlying trait variance. The first PC (PC1), which consisted primarily of poor pulmonary and physical function, represented 14.3% of the total variance and had an estimated heritability of 39%. PC2 consisted of measures of good metabolic and cardiovascular function with an estimated heritability of 27%. PC3 was made up of cognitive measures (h(2) = 36%). PC4 and PC5 contained measures of blood pressure and cholesterol, respectively (h(2) = 25% and 16%). CONCLUSIONS These PCs analysis-derived endophenotypes may be used in genetic association studies to help identify underlying genetic mechanisms that drive exceptional survival in this and other populations.

Abstract
Tumor necrosis factor (TNF) is an immunomodulatory cytokine that plays an important role in many inflammatory and autoimmune diseases. We investigated the correlation between single-nucleotide polymorphisms of the TNF gene [i.e., TNF-α (308), TNF-α (857), TNF-α (863), TNF-α (1031), and TNF-ß (+252)] and dilated cardiomyopathy (DCM). A total of 110 DCM patients and 110 control subjects were genotyped using polymerase chain reaction-restriction fragment length polymorphism and DNA-sequencing assay. GA=AA genotypes of TNF-α (308) were significantly associated with increased risk of DCM compared with GG genotype (odds ratio[OR]=1.92; 95% confidence intervals [CI], 1.05-3.52). Similarly, GA=AA of TNF-ß (+252) was significantly associated with increased risk of DCM compared with GG genotype (OR=1.97; 95% CI, 1.14-3.38). Additionally, A allele of TNF-α (-308) and TNF-ß (+252) was associated with a 1.76-fold increased risk of DCM compared with G allele (OR=1.76; 95% CI, 1.05-2.95 and OR=1.79; 95% CI, 1.22-2.63, respectively). However,no association between DCM and TNF-α (857), TNF-α (1031), and TNF-α (863) was observed. TNF gene polymorphisms may be associated with risk of DCM.

Abstract
Adverse housing and neighborhood conditions are independently associated with an increased risk of various diseases and conditions. One possible explanation relates to systemic inflammation, which is associated with these adverse health outcomes. The authors investigated the association between housing and neighborhood conditions with inflammatory markers using data about 352 persons aged 49-65 years from the African American Health study. Participants were identified by a multistage random selection process in 2000 to 2001(response rate, 76%). Blood was analyzed for soluble cytokine receptors (interleukin-6, tumor necrosis factor alpha), C-reactive protein, and adiponectin. Neighborhood and housing characteristics consisted of five observed block face conditions (external appearance of the block on which the subject lived), four perceived neighborhood conditions, four observed housing conditions (home assessment by the interviewers rating the interior and exterior of the subject's building), and census-tract level poverty rate from the 2000 census. Differences in some inflammatory markers were found by age, gender, chronic conditions, and body mass index (all Bonferroni-adjusted p < 0.0034). There was no association between any of the housing/neighborhood conditions and the pro-inflammatory markers and potential associations between some housing/neighborhood conditions and adiponectin (p < 0.05, Bonferroni-adjusted p > 0.0034). Inflammation does not appear to be a mediator of the association between poor housing/neighborhood conditions and adverse health outcomes in middle-aged African Americans.
