Objectives

Hand grip measures offer potential indicators for recovery after hospitalization in older adults. We investigated prospective associations of the grip indicators maximal grip strength (GSmax), fatigue resistance (FR) and grip work (GW) with post-discharge functional limitations, health-related quality of life (HRQOL) and survival in older inpatients.

Methods

Grip indicators were evaluated at admission in general geriatric inpatients (GGI, n = 149) and geriatric hip fracture inpatients (HIP, n = 109). Questionnaires on functional limitations (10–40, lower is better) were collected for two weeks pre-admission, admission, three months follow-up, and six months follow-up. HRQOL (−4–10, higher is better) was assessed at admission, three months follow-up and six months follow-up. With individual growth modeling, we established the associations between grip indicators and the outcome trajectories. Three-month survival was analyzed using Cox proportional hazards models.

Results

In GGI, higher FR and GW were associated with better functional recovery from admission to three months follow-up (FR: B = −1.0 points per 10s increase, 95 %CI −1.9, −0.14; GW: B = −0.33 points per 100 kPa × s increase, 95 %CI −0.59, −0.07). HIP with higher grip indicators showed a better functional recovery towards three months follow-up (GSmax: B = −2.4 per 10 kPa increase, 95 %CI −3.9, −0.89; FR: B = −1.1, 95 %CI −2.4, 0.20; GW: B = −0.31, 95 %CI −0.61, −0.02). No or weak associations were found between grip indicators and HRQOL recovery. Hazard ratios pointed towards a better survival for better scores on grip indicators, but associations were not statistically significant.

Conclusion

Higher FR and GW at admission were associated with better recovery post-discharge in geriatric inpatients. Future research should examine the added clinical value of grip indicators in addition to known patient characteristics.
目的:手部握力测量为老年人住院后康复提供潜在指标。我们研究了握力指标最大握力(GSmax)、疲劳阻力(FR)和握力功(GW)与老年住院患者出院后功能限制、健康相关生活质量(HRQOL)和生存率的前瞻性关联。方法:对普通老年住院患者(GGI, n = 149)和老年髋部骨折住院患者(hip, n = 109)入院时握力指标进行评价。在入院前2周、入院后3个月、随访6个月收集功能限制问卷(10-40份,越低越好)。入院时评估HRQOL(-4-10,越高越好),随访3个月和6个月。通过个体成长模型,我们建立了握力指标与结果轨迹之间的关联。采用Cox比例风险模型分析3个月生存率。结果:在GGI,更高的FR和瓦与更好的功能恢复从入学到三个月随访(FR: B = -1.0分10年代增加,CI 95 % -1.9,-0.14;温伯格:B = -0.33分100 kPa × 年代增加,CI 95 % -0.59,-0.07)。臀部高控制指标显示更好的功能恢复对三个月随访(GSmax: B = 每10 -2.4 kPa增加,95年 % -3.9 CI, -0.89; FR: B = -1.1,-2.4 95 % CI, 0.20;温伯格:B = -0.31,-0.61 95 % CI, -0.02)。握力指标与HRQOL恢复之间无或弱关联。风险比表明,握力指标得分越高,存活率越高,但相关关系在统计上并不显著。结论:老年住院患者入院时FR和GW较高,出院后恢复较好。除了已知的患者特征外,未来的研究应检查握力指标的附加临床价值。

Objective

Vascular aging is a critical risk factor for the development and progression of cardiovascular diseases. Age-related degenerative changes in vascular structure and function significantly promote the onset of various vascular disorders. Currently, the specific molecular mechanisms underlying age-associated vascular structural and functional decline have not been fully elucidated. Ginsenoside Rb1 (Rb1), as the primary active component of ginseng, has been confirmed to possess potential anti-aging properties. This study aims to investigate the protective effects of Rb1 on the aorta in aged mice and its underlying molecular mechanisms, thereby providing experimental evidence and theoretical support for the screening of natural anti-vascular aging drugs.

Methods

Naturally aged (72-week-old) male C57BL/6J mice were randomly divided into two groups (n = 5 per group) to receive intraperitoneal injections of either PBS (Old group) or 20 mg/kg Rb1 (Old + Rb1 group) for 6 weeks. Young mice (12-week-old, n = 5) served as controls. Aortic tissues were analyzed using histomorphology (hematoxylin and eosin, H&E), nanoscale biomechanics (Atomic Force Microscopy, AFM), senescence biomarkers (P21 immunofluorescence, SA-β-gal staining), apoptosis (TUNEL assay), and DNA damage (γ-H2AX).

Results

Compared to the Old group, Rb1 significantly alleviated structural remodeling of the aging aorta, restoring smooth muscle cell alignment and extracellular matrix. AFM analysis showed that Rb1 ameliorated the aging-induced impairments in nanobiomechanical properties (including elasticity, viscosity, and surface topography) induced by aging. Furthermore, Rb1 treatment downregulated the expression of P21 in the aorta, reduced the positive area percentage of SA-β-gal positivity, and decreased the proportion of TUNEL-positive apoptotic cells, although none of these indicators were comparable to the levels observed in the Young control group. Notably, Rb1 significantly alleviates the elevation of γ-H2AX (a marker of DNA double-strand breaks) in the aging aorta.

Conclusion

This study demonstrates that Rb1 attenuates DNA damage, thus ameliorating structural remodeling and biomechanical function of the aging aorta, and delaying vascular aging and apoptosis. Our findings suggest that Rb1 counteracts age-related aortic impairment, potentially by targeting the DNA damage pathway, which highlights its therapeutic potential against vascular aging.
目的:血管老化是心血管疾病发生发展的重要危险因素。年龄相关的血管结构和功能退行性改变显著促进各种血管疾病的发生。目前,与年龄相关的血管结构和功能衰退的具体分子机制尚未完全阐明。人参皂苷Rb1 (Ginsenoside Rb1, Rb1)作为人参的主要活性成分,已被证实具有潜在的抗衰老作用。本研究旨在探讨Rb1对衰老小鼠主动脉的保护作用及其分子机制,为天然抗血管衰老药物的筛选提供实验依据和理论支持。方法:将自然衰老(72周龄)雄性C57BL/6J小鼠随机分为两组(每组 = 5只),分别腹腔注射PBS (Old组)和20 mg/kg Rb1 (Old + Rb1组),注射时间为6 周。幼鼠(12周龄,n = 5)作为对照。采用组织形态学(苏木精和伊红,H&E)、纳米尺度生物力学(原子力显微镜,AFM)、衰老生物标志物(P21免疫荧光,SA-β-gal染色)、细胞凋亡(TUNEL试验)和DNA损伤(γ-H2AX)对主动脉组织进行分析。结果:与Old组相比,Rb1显著缓解了老化主动脉的结构重塑,恢复了平滑肌细胞排列和细胞外基质。AFM分析表明,Rb1改善了老化引起的纳米生物力学性能(包括弹性、粘度和表面形貌)的损伤。此外,Rb1处理下调了主动脉P21的表达,降低了SA-β-gal阳性的阳性面积百分比,降低了tunel阳性凋亡细胞的比例,尽管这些指标都无法与Young对照组的水平相比。值得注意的是,Rb1显著缓解了老化主动脉中γ-H2AX (DNA双链断裂的标志)的升高。结论:Rb1可减轻DNA损伤,从而改善老化主动脉的结构重塑和生物力学功能,延缓血管老化和细胞凋亡。我们的研究结果表明,Rb1可能通过靶向DNA损伤途径抵消与年龄相关的主动脉损伤,这突出了其治疗血管衰老的潜力。

Backgrounds

Preserving intrinsic capacity (IC) is essential for healthy aging. This study examined the associations between longitudinal changes in IC and subsequent adverse health outcomes.

Methods

Participants were community-dwelling adults aged ≥60 years from the China Health and Retirement Longitudinal Study (CHARLS). Changes in IC between 2011 and 2013 were classified as consistently well, improved, worsened, or consistently declined. Logistic regression assessed associations with falls and hospitalization (2015), and Cox models evaluated all-cause mortality (2020).

Results

Changes in IC were significant predictors of adverse outcomes. Worsened (OR = 1.674, 95 % CI: 1.163–2.411, P = 0.006) and consistently declined changes in IC (OR = 1.914, 95 % CI: 1.373–2.668, P < 0.001) were both associated with an increased risk of falls, while domain-specific changes, such as worsened locomotion, consistently declined in cognition and fluctuations in psychology or vision, were also linked to increased fall risk (all P < 0.017). Both consistently declined IC (OR = 1.513, 95 % CI: 1.079–2.122, P < 0.017) and worsened locomotion were independent predictors of hospitalization (OR = 1.837, 95 % CI: 1.265–2.670, P = 0.001). Declines in locomotion were also strongly associated with mortality, with higher risk observed in the worsened group (HR = 1.571, 95 % CI: 1.088–2.267, P < 0.017).

Conclusions

Monitoring intrinsic capacity changes, especially locomotion decline, enables early identification of vulnerable older adults and supports timely, targeted interventions to reduce adverse outcomes.

Introduction

It has been suggested that two prominent frameworks in geriatrics, frailty and intrinsic capacity (IC), represent two opposite ends of the same continuum. Frailty quantifies accumulated deficits and vulnerability, and IC measures an individual's capacities and functional reserves. This study investigates the overlap between frailty and IC in a large cohort of older adults.

Methods

We analysed 3246 participants aged 55+ from the Longitudinal Aging Study Amsterdam. Participants were categorised into four groups: neither frail nor low IC, low IC only, frail only, and both frail and low IC. Overlap was examined across age groups. Domain scores (vitality, sensory, cognition, psychology, locomotion) were compared between groups.

Results

Among 57–59 year olds, only 2.2 % were both frail and had low IC. This proportion increased with age, reaching 53.6 % at ages 87–89, while the “frail only” and “low IC only” groups declined. Overlap between frailty and domain scores showed that the “Neither” group consistently had the highest IC scores across all five domains, while the “Both” group consistently had the lowest scores.

Conclusions

In later life, being frail does not necessarily imply low IC, and vice versa. Frailty and low IC identify different groups in early older age, but the overlap between them becomes more pronounced with increasing age. Comprehensive assessment of ageing therefore requires measures that capture both vulnerability to decline and capacity.
有人认为,在老年病学的两个突出的框架,脆弱和内在能力(IC),代表了同一个连续体的两个相反的两端。脆弱量化累积的缺陷和脆弱性,IC衡量个人的能力和功能储备。本研究调查了大量老年人中虚弱和IC之间的重叠。方法我们分析了来自阿姆斯特丹纵向老龄化研究的3246名55岁以上的参与者。参与者被分为四组:既不虚弱也不低IC,只有低IC,只有虚弱,虚弱和低IC。在不同年龄组中检查重叠。各组间各领域评分(活力、感觉、认知、心理、运动)比较。结果在57 ~ 59岁的人群中,体弱多病和低IC的比例仅为2.2%,随着年龄的增长,这一比例在87 ~ 89岁时达到53.6%,而“体弱多病”和“低IC”组则有所下降。脆弱和领域得分之间的重叠表明,“两者都不是”组在所有五个领域中始终具有最高的IC得分,而“两者都是”组始终具有最低的得分。结论在晚年,身体虚弱并不一定意味着IC低,反之亦然。在老年早期,虚弱和低IC是不同的群体,但随着年龄的增长,它们之间的重叠变得更加明显。因此,全面评估老龄化问题需要采取措施,既要考虑到衰退的脆弱性,也要考虑到能力。

Background

Insulin resistance (IR) and inflammation are two crucial risk factors of sarcopenia. C-reactive protein-triglyceride glucose index (CTI) has been proposed to be a novel biomarker reflecting IR and inflammation. However, association between CTI and sarcopenia risk remains unclear.

Aim

To explore the association between CTI and sarcopenia risk.

Methods

Data were obtained from Nutrition Examination Survey (NHANES) 2001–2010 and China Health and Retirement Longitudinal Study (CHARLS) 2011–2015. NHANES was used for cross-sectional analysis, and weighted logistic regression analysis was conducted to explore association between CTI and sarcopenia. CHARLS was used for longitudinal analysis, and the primary endpoint was the first occurrence of sarcopenia over follow-up. Logistic regression analysis and Cox proportional hazard analysis were conducted to explore the relationship between CTI and the risk of sarcopenia. Restricted cubic spline (RCS) analysis was performed to investigate the non-linear association between CTI and sarcopenia risk, and receiver operating characteristics (ROC) curves and the area under the ROC curve (AUC) were utilized to assess the predictive capability of CTI on the risk of sarcopenia.

Results

A total of 11,286 Americans and 1478 Chinese aged ≥60 years were included in this study. Logistic and Cox regression analysis revealed the cross-sectional (OR: 1.52, 95 %CI: 1.15–1.99, P = 0.004) and longitudinal (HR: 1.35, 95 %CI: 1.10–1.65, P = 0.004) correlation between CTI and sarcopenia risk after adjusting the covariates. For the two databases, non-linear association between CTI and sarcopenia risk was observed (P for non-linear <0.001). Additionally, compared to CRP and the TyG index, CTI exhibited the best predictive capability for sarcopenia risk, with the highest AUC (CHARLS: 0.730, NHANES: 0.722).

Conclusion

There exist both the cross-sectional and longitudinal association between CTI level and sarcopenia risk in older adults, and it is crucial to monitor CTI in the prevention and treatment of sarcopenia.
背景:胰岛素抵抗(IR)和炎症是肌肉减少症的两个重要危险因素。c反应蛋白-甘油三酯葡萄糖指数(CTI)被认为是反映IR和炎症的一种新的生物标志物。然而,CTI与肌少症风险之间的关系尚不清楚。目的探讨CTI与肌少症风险的关系。方法数据来源于2001-2010年营养检查调查(NHANES)和2011-2015年中国健康与退休纵向研究(CHARLS)。采用NHANES进行横断面分析,并进行加权logistic回归分析,探讨CTI与肌肉减少症的关系。采用CHARLS进行纵向分析,主要终点为随访期间首次出现肌肉减少症。采用Logistic回归分析和Cox比例风险分析探讨CTI与肌少症风险的关系。采用限制性三次样条(RCS)分析CTI与肌少症风险之间的非线性关系,并利用受试者工作特征(ROC)曲线和ROC曲线下面积(AUC)评估CTI对肌少症风险的预测能力。结果共纳入年龄≥60岁的美国人11,286人,中国1478人。Logistic回归分析和Cox回归分析显示,调整协变量后,CTI与肌少症风险存在截面相关性(OR: 1.52, 95% CI: 1.15 ~ 1.99, P = 0.004)和纵向相关性(HR: 1.35, 95% CI: 1.10 ~ 1.65, P = 0.004)。在这两个数据库中,观察到CTI与肌肉减少症风险之间存在非线性关联(P为非线性<;0.001)。此外,与CRP和TyG指数相比,CTI对肌肉减少症风险的预测能力最好,AUC最高(CHARLS: 0.730, NHANES: 0.722)。结论CTI水平与老年人骨骼肌减少症风险存在横断面和纵向相关性,监测CTI在预防和治疗骨骼肌减少症中具有重要意义。

Background

Musculoskeletal pain (MSP) is prevalent among middle-aged and older adults and may increase fall risk through functional decline, but evidence on pain persistence and the potential role of frailty in China remains limited.

Methods

This study utilized data from the 2011 and 2015 China Health and Retirement Longitudinal Study (CHARLS), involving 13,057 participants in 2011 and a cohort of 7390 who reported no falls in 2011 and completed the 2015 follow-up. Among them, 1046 had persistent MSP identified using standardized CHARLS pain items. Participants indicated body pain locations, with MSP noted if pain was present anywhere. Baseline MSP was recorded in 2011, and persistent MSP was reported in both 2011 and 2015. Falls were self-reported. Survey-weighted logistic regression analyzed associations, while mediation analyses used baseline MSP (2011) as exposure and frailty in 2015 as a mediator, employing a counterfactual framework to decompose effects, interpreted cautiously due to standard assumptions and a two-year fall recall window. Baseline characteristics were compared between included and excluded participants to evaluate potential selection bias.

Results

In the longitudinal cohort, 1072 incident falls were recorded, with a higher fall rate among participants with persistent MSP than among those without (25.69 % vs 12.48 %). Adjusted models showed baseline MSP increased fall risk (OR 1.36, 95 % CI 1.15–1.60), with a stronger link for persistent MSP (OR 2.08, 95 % CI 1.70–2.54). Similar trends were observed for multisite pain. Mediation analysis indicated frailty partially mediated the effect of baseline MSP on falls, accounting for about 29 % of the effect, though results were interpreted cautiously due to the two-year fall recall period.

Conclusions

In middle-aged and older Chinese adults, MSP increases fall risk, particularly with ongoing pain. Frailty might partly explain this risk, indicating the importance of combining pain management with anti-frailty measures for fall prevention.
背景:肌肉骨骼疼痛(MSP)在中老年人中普遍存在,并可能通过功能下降增加跌倒风险,但在中国,关于疼痛持续性和虚弱的潜在作用的证据仍然有限。方法:本研究利用了2011年和2015年中国健康与退休纵向研究(CHARLS)的数据,该研究涉及2011年的13057名参与者和7390名2011年未报告跌倒并完成2015年随访的队列。其中1046例使用标准化CHARLS疼痛项目确诊为持续性MSP。参与者指出身体疼痛的位置,MSP记录疼痛是否存在于任何地方。基线MSP记录于2011年,持续MSP报告于2011年和2015年。跌倒是自我报告的。调查加权逻辑回归分析了关联,而中介分析使用基线MSP(2011年)作为暴露,2015年脆弱性作为中介,采用反事实框架分解效应,由于标准假设和两年的秋季回忆窗口,解释谨慎。比较纳入和未纳入受试者的基线特征,以评估潜在的选择偏倚。结果在纵向队列中,记录了1072例跌倒事件,持续性MSP参与者的跌倒率高于非持续性MSP参与者(25.69% vs 12.48%)。调整后的模型显示,基线MSP增加跌倒风险(OR 1.36, 95% CI 1.15-1.60),与持续性MSP有更强的联系(OR 2.08, 95% CI 1.70-2.54)。多部位疼痛也有类似的趋势。中介分析表明,虚弱部分介导了基线MSP对跌倒的影响,约占29%的影响,尽管由于两年的跌倒回忆期,结果被谨慎地解释。结论:在中国中老年成年人中,MSP增加跌倒风险,特别是持续疼痛。虚弱可能部分解释了这种风险,表明将疼痛管理与抗虚弱措施结合起来预防跌倒的重要性。

Objective

Chronotype represents individual's circadian preference in behavioral and circadian rhythm. This study aimed to investigate association between chronotype and nonalcoholic fatty liver disease (NAFLD) and underlying metabolic mechanisms in middle-aged and older adults.

Methods

This cross-sectional study included 744 general middle-aged and older adults. Chronotype was assessed using the Morningness-Eveningness Questionnaire. Untargeted metabolomic profiling was identified using liquid chromatography with high-resolution mass spectrometry. Logistic regression model was used to evaluate association between chronotype and NAFLD. A metabolome-wide association study coupled with mediation analysis was conducted to assess metabolic dysregulation related with chronotype and NAFLD.

Results

Chronotype was categorized as morning in 33.1 % of participants, intermediate in 46.8 %, and evening in 20.1 %. After adjustment for covariates, evening chronotype was significantly associated with higher NAFLD risk (OR = 1.70, 95 % CI: 1.03, 2.81) compared to morning chronotype. We identified 81 metabolite features that were significantly associated with chronotype. The comparison between NAFLD and non-NAFLD revealed 251 metabolic differences, implicating 5 metabolic pathways: Arginine biosynthesis, Histidine metabolism, Alanine, aspartate and glutamate metabolism, Arginine and proline metabolism, and beta-Alanine metabolism. Mediation analyses suggested that 7 metabolites (such as Asparaginyl-Proline and DG(11D3/11D5/0:0)) might be potential mediators in association of chronotype with NAFLD, with mediated proportions ranging from 12.1 % to 20.6 %.

Conclusion

Evening chronotype was associated with increased risk of NAFLD in middle-aged and older adults. Chronotype-related metabolomic alterations, including Asparaginyl-Proline and some lipid metabolites, might represent an associative pathway between chronotype and NAFLD. This highlighted the importance of maintaining circadian rhythms for metabolic health.
目的:时间型反映了个体在行为和昼夜节律方面的生理偏好。本研究旨在探讨中老年人睡眠类型与非酒精性脂肪性肝病(NAFLD)之间的关系及其潜在的代谢机制。方法:本横断面研究纳入744名普通中老年人。时间类型评估使用晨醒性问卷。使用液相色谱和高分辨率质谱法鉴定非靶向代谢组学分析。采用Logistic回归模型评价睡眠类型与NAFLD的相关性。一项代谢组关联研究结合中介分析来评估代谢失调与时间型和NAFLD的关系。结果:33.1% %的参与者的睡眠类型为早晨,46.8% %的参与者为中间,20.1% %的参与者为晚上。调整协变量后,与晨起型相比,晚睡型与NAFLD风险显著相关(OR = 1.70,95 % CI: 1.03, 2.81)。我们确定了81个与时间型显著相关的代谢物特征。NAFLD与非NAFLD的比较发现了251种代谢差异,涉及5种代谢途径:精氨酸生物合成、组氨酸代谢、丙氨酸、天冬氨酸和谷氨酸代谢、精氨酸和脯氨酸代谢、β -丙氨酸代谢。中介分析表明,7种代谢物(如天冬酰胺脯氨酸和DG(11D3/11D5/0:0))可能是与NAFLD相关的潜在中介,介导比例在12.1 %至20.6 %之间。结论:夜间睡眠类型与中老年人NAFLD风险增加有关。时间型相关的代谢组学改变,包括天冬酰胺脯氨酸和一些脂质代谢物,可能代表了时间型和NAFLD之间的关联途径。这突出了维持昼夜节律对代谢健康的重要性。

Introduction

Menopause is associated with immunosenescence and altered immune profiles, potentially reducing immune competence. Physical exercise may counteract these changes by modulating DNA methylation in fitness-related genes.

Methods

This observational bioinformatics study analyzed genome-wide DNA methylation profiles derived from whole blood using two publicly available datasets from Brazilian cohorts (Illumina MethylationEPIC 850K). The analysis included pre- (PreM, n = 13; 34 ± 4.7 years) and postmenopausal (PostM, n = 49; 59.8 ± 4.7 years) women who completed supervised combined exercise training. Four linear models were applied to examine associations between DNA methylation, cardiorespiratory fitness (VO₂ peak), and exercise intervention (pre- vs. post-training), while adjusting for age, fat percentage, and estimated immune-cell proportions (EpiDISH). Interaction terms were tested to assess whether immune cell composition or menopausal status modulated the relationship between VO₂ peak, exercise response, and DNA methylation.

Results

After adjusting for baseline values using analysis of covariance (ANCOVA), no statistically significant between-group differences were observed in the estimated immune cell proportions (FDR > 0.05). In PostM, exercise-induced DNA methylation changes were significantly associated with baseline VO₂ peak and were modulated by B cells, CD4+ T cells, NK cells, and monocytes. Functional enrichment highlighted pathways involved in lipid kinase regulation, nucleobase metabolism, and membrane organization.

Conclusion

Postmenopausal women showed distinct epigenetic patterns in response to exercise, although these differences must be interpreted cautiously given the small premenopausal sample size. These results suggest potential immune cell–associated DNA methylation markers to inform personalized exercise strategies supporting healthy aging in women.
更年期与免疫衰老和免疫谱改变有关,可能降低免疫能力。体育锻炼可以通过调节健康相关基因的DNA甲基化来抵消这些变化。方法:这项观察性生物信息学研究使用来自巴西队列的两个公开数据集(Illumina MethylationEPIC 850K)分析了来自全血的全基因组DNA甲基化谱。分析包括前置(PreM n = 13;34 ±4.7  年)和绝经后(59.8 n = 49 PostM; ±4.7  年)女性完成指导运动训练相结合。应用四个线性模型来检查DNA甲基化,心肺健康(vo2峰值)和运动干预(训练前与训练后)之间的关系,同时调整年龄,脂肪百分比和估计的免疫细胞比例(EpiDISH)。相互作用项进行测试,以评估免疫细胞组成或绝经状态是否调节vo2峰值、运动反应和DNA甲基化之间的关系。结果:在使用协方差分析(ANCOVA)调整基线值后,估计免疫细胞比例在组间无统计学差异(FDR > 0.05)。在PostM中,运动诱导的DNA甲基化变化与基线vo2峰值显著相关,并受到B细胞、CD4+ T细胞、NK细胞和单核细胞的调节。功能富集强调了涉及脂激酶调节、核碱基代谢和膜组织的途径。结论:绝经后妇女对运动表现出明显的表观遗传模式,尽管考虑到绝经前样本量小,这些差异必须谨慎解释。这些结果表明,潜在的免疫细胞相关DNA甲基化标记可以为支持女性健康衰老的个性化运动策略提供信息。

This study aimed to examine whether resting-state EEG markers show potential for distinguishing individuals as healthy control, mild cognitive impairment (MCI), and motoric cognitive risk syndrome (MCR), based on their levels of cognitive and motor decline. In this cross-sectional study, we enrolled 87 participants and classified them into three groups. Motor functions were measured by gait speed. Cognitive function was assessed by neuropsychologists using standardized tools, including the Mini-Mental State Examination (MMSE), the Symbol Digit Substitution Test (SDST), and the Paired Associates Learning (PAL) task. Resting-state EEG data were recorded for five minutes with eyes closed, using a 19-channel wireless EEG system. Our results showed that individuals with MCI and MCR exhibited increased frontal theta power and widespread default mode network (DMN) connectivity, reflecting underlying neuropsychological changes. These alterations were most pronounced in the MCR group and were associated with both cognitive and motor decline. Our findings highlight the potential of resting-state EEG as a biomarker for the early detection of cognitive and motor decline in community-dwelling older adults.
本研究旨在研究静息状态EEG标记是否显示基于认知和运动衰退水平区分健康对照组、轻度认知障碍(MCI)和运动认知风险综合征(MCR)个体的潜力。在这项横断面研究中,我们招募了87名参与者,并将其分为三组。通过步态速度测量运动功能。认知功能由神经心理学家使用标准化工具进行评估,包括简易精神状态检查(MMSE)、符号数字替代测试(SDST)和配对联想学习(PAL)任务。采用19通道无线脑电图系统,闭眼记录静息状态脑电图数据5分钟。我们的研究结果表明,患有轻度认知障碍和轻度认知障碍的个体表现出增加的额叶θ波功率和广泛的默认模式网络(DMN)连接,反映了潜在的神经心理变化。这些改变在MCR组中最为明显,并且与认知和运动能力下降有关。这些发现突出了静息状态脑电图作为早期检测社区居住老年人认知和运动衰退的生物标志物的潜力。

Our findings highlight the potential of resting-state EEG as a biomarker for the early detection of cognitive and motor decline in community-dwelling older adults.</div></div>","PeriodicalId":94003,"journal":{"name":"Experimental gerontology","volume":"213 ","pages":"Article 113000"},"PeriodicalIF":4.3,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145776963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This cross-sectional study investigates the association between the Food Inflammation Scores of Individuals (FISI34, FISI26-USDA, FISI26-CHINA), derived from the Food Inflammation Index (FII), and sarcopenia in 5489 U.S. adults from the National Health and Nutrition Examination Survey (NHANES 2011–2018). Sarcopenia was defined using appendicular lean mass adjusted for body mass index (BMI). Logistic regression and restricted cubic spline analyses revealed significant positive associations between higher FISI and sarcopenia prevalence, with odds ratios ranging from 1.13 to 1.39 in fully adjusted models. Stronger associations were observed in females, adults aged ≥40 years, Mexican Americans, and those with higher BMI or chronic conditions like hypertension and cardiovascular disease, though no significant interaction effects were observed (p-interaction >0.05). FISI, incorporating individual dietary intake and nutrient reference values, offers a personalized approach compared to the Dietary Inflammatory Index (DII), supporting the evaluation of targeted dietary strategies to address sarcopenia.
这项横断面研究调查了5489 美国个体食物炎症指数(FII)的食物炎症评分(FISI34, FISI26-USDA, FISI26-CHINA)与肌肉减少症之间的关系来自全国健康和营养检查调查(NHANES 2011-2018)的成年人。骨骼肌减少症的定义采用经身体质量指数(BMI)调整的阑尾瘦质量。Logistic回归和限制性三次样条分析显示,高FISI与肌肉减少症患病率之间存在显著正相关,在完全调整模型中,比值比为1.13至1.39。在女性、年龄≥40 岁的成年人、墨西哥裔美国人以及BMI较高或患有高血压和心血管疾病等慢性疾病的人群中观察到更强的相关性,但没有观察到显著的相互作用效应(p-相互作用>0.05)。与膳食炎症指数(DII)相比,FISI结合了个人膳食摄入量和营养参考值,提供了一种个性化的方法,支持评估有针对性的饮食策略,以解决肌肉减少症。
