背景和目的苦胆病是一种复杂的代谢紊乱,以体重减轻、肌肉萎缩和炎症为特征,通常与慢性疾病相关。然而,恶病质在社区居民、中老年人中的发生情况仍未得到充分研究。本研究旨在评估50岁及以上成人恶病质、内在能力(IC)损伤和死亡率之间的关系。方法:我们汇集了三项纵向队列研究的数据,其中包括3112名年龄在50岁及以上的个体。使用亚洲恶病质工作组(AWGC)提出的两种算法定义恶病质表型,即使在没有特定指数疾病的情况下。对于算法1,当患者出现体重减轻或低体重指数(BMI)并伴有以下情况之一时,患者被确定为患有恶病质:厌食症、握力下降或c反应蛋白(CRP)水平升高。对于算法2,识别恶病质需要CRP水平升高,同时体重减轻或低BMI,并伴有厌食症或握力下降。重要的是,使用这些标准来定义恶病质表型并不需要特定指数疾病的存在。相反,我们筛选了以下指标疾病作为合并症:恶性肿瘤,充血性心力衰竭,慢性肺病,慢性肾病,严重肝病,风湿病或免疫疾病,以及获得性免疫缺陷综合征(艾滋病)。使用世界卫生组织的ICOPE框架(第1步筛查;第2步深入评估)对IC进行评估,其中包括六个领域:运动、活力、视觉、听觉、认知和心理能力。采用Logistic回归评估恶病质与IC损伤之间的关系,采用Cox比例风险模型检验恶病质对全因死亡率的影响。结果在三个队列的3112名参与者(中位年龄68.8岁,43.7%为男性)中,使用算法1确定5.4%的参与者具有恶病质表型,而只有0.4%的参与者符合算法2的标准。值得注意的是,只有22%的具有恶病质表型(算法1)的参与者至少有一种筛查的指标疾病,而非恶病质组的这一比例为12% (p < 0.001)。这些发现表明,即使在没有特定指数疾病的情况下,恶病质表型也可以被识别。恶病质表型与多个IC领域的损伤显著相关,包括活力(步骤1:aOR 8.44 [95% CI 5.15-13.83], p < 0.001;步骤2:aOR 15.89 [10.72-23.56], p < 0.001)、认知(步骤1:aOR 1.75 [1.17-2.62], p = 0.007)和心理能力(步骤2:aOR 2.56 [1.39-4.73], p = 0.003)。校正混杂因素后,恶病质表型个体的死亡风险显著高于非恶病质组(aHR 1.77 [95% CI 1.15-2.73], p = 0.010)。结论在没有特定指标疾病的情况下,恶病质表型与中老年人IC损伤和死亡率增加有关。早期识别和有针对性的干预对于减轻恶病质表型患者的功能衰退和提高生存率至关重要。

Background and aims
One potential adverse effect of protein loading in critically ill patients is elevated blood urea nitrogen (BUN) concentrations. Along with kidney function, we hypothesized that muscle volume also affects the BUN trajectory with protein administration.
Methods
A post-hoc analysis was conducted of a prospective historical control study in which intensive care unit (ICU) patients were assigned to protein delivery targets of 0.9 and 1.8 g/kg/day over 10 days. Patients who received renal replacement therapy were excluded. Femoral muscle volume FMV was evaluated by computed tomography on ICU admission. Daily BUN and protein delivery were recorded throughout the 10 days.
Results
Eighty-two eligible patients were analyzed. The BUN trajectories were slightly higher in patients with a lower muscle volume. The relative ratio of total protein delivery over 10 days to FMV showed a positive correlation with the BUN concentration on day 10 (r = 0.37, p = 0.0007); while this relationship was not significant with protein intake to actual body weight (r = 0.22, p = 0.068). In the linear mixed-effects model, protein intake per FMV was significantly associated with higher blood BUN concentrations (coefficient 0.07, 95 % CI 0.01 to 0.13, p = 0.02). Simultaneously, age and baseline creatinine were also significant predictors of BUN concentrations.
Conclusions
In critically ill patients, the relative ratio of total protein delivery to muscle volume was associated with BUN elevations. Protein targets may be more appropriately set based on muscle volume, for example, by using the grams per fat-free mass calculation.

背景和目的:危重患者蛋白质负荷的一个潜在不良影响是血尿素氮(BUN)浓度升高。除了肾功能外,我们假设肌肉体积也会影响蛋白质给药后的BUN轨迹。方法:对一项前瞻性历史对照研究进行事后分析,在该研究中,重症监护病房(ICU)患者在10天内被分配到0.9和1.8 g/kg/天的蛋白质递送目标。接受肾脏替代治疗的患者排除在外。在ICU入院时通过计算机断层扫描评估股骨肌体积FMV。在10天内记录每日BUN和蛋白质递送量。结果:分析了82例符合条件的患者。在肌肉体积较小的患者中,BUN轨迹略高。10 d总蛋白递送量与FMV的相对比值与第10 d BUN浓度呈正相关(r = 0.37, p = 0.0007);而蛋白质摄入量与实际体重之间的关系不显著(r = 0.22, p = 0.068)。在线性混合效应模型中,每FMV蛋白质摄入量与较高的血尿素氮浓度显著相关(系数0.07,95% CI 0.01 ~ 0.13, p = 0.02)。同时,年龄和基线肌酐也是BUN浓度的重要预测因子。结论:危重患者总蛋白递送量与肌肉体积的相对比值与BUN升高有关。蛋白质目标可能更适合根据肌肉体积来设定,例如,通过使用克/无脂质量计算。注册:本研究在大学医院医学信息网临床试验注册中心注册(UMIN000040290,注册日期:2020年5月7日);https://center6.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000045970。

Background and aims
Disagreement between bioelectrical impedance analysis (BIA) technologies in measuring resistance (R), reactance (Xc), and phase angle (PhA) is well documented and mainly due to device-specific features. Whether such a variability translates into differences in body composition estimates remains uncertain. This study evaluated agreement in fat-free mass (FFM) estimates from different BIA technologies against dual-energy X-ray absorptiometry (DXA), while accounting for the role of predictive equations. Additionally, agreement of BIA-based fat mass (FM), indirectly calculated from FFM, was assessed.
Methods
A total of 288 adults (167 men, 37.2 ± 18.7 y, BMI 23.0 ± 3.1 kg/m2; 121 women, 33.8 ± 16.8 y, BMI 25.1 ± 3.3 kg/m2) participated in this study. Whole-body foot-to-hand and direct segmental BIA at 50 kHz measured R, Xc, and PhA. DXA served as the reference. Predictive equations for FFM were developed by stepwise regression in two-thirds of the sample and validated in the remaining third. Agreement was evaluated between BIA technologies and against DXA using Bland–Altman and Lin's concordance correlation coefficient.
Results
Foot-to-hand BIA yielded lower R (p < 0.001) but higher Xc and PhA (p < 0.001) than direct segmental BIA. Despite these differences, no significant bias (p > 0.05) was observed in FFM estimation across devices. Concordance analyses indicated high agreement without systematic deviations. FM derived from FFM agreed with DXA at a group level but showed systematic trends at the individual level.
Conclusions
Although raw bioelectrical parameters differ between technologies, FFM estimates can be comparable when equations are derived within the same population and reference method. However, FM indirectly obtained from FFM lacks accuracy at the individual level.
背景和目的生物电阻抗分析(BIA)技术在测量电阻(R)、电抗(Xc)和相角(PhA)方面的分歧是有案可查的,主要是由于器件的特定特性。这种差异是否会转化为身体成分估计值的差异仍不确定。本研究评估了不同BIA技术对双能x射线吸收测定法(DXA)的无脂质量(FFM)估计值的一致性,同时考虑了预测方程的作用。此外,评估了从FFM间接计算的基于bia的脂肪量(FM)的一致性。方法共288例成人(男性167例,37.2±18.7 y, BMI 23.0±3.1 kg/m2);女性121例,33.8±16.8 y, BMI 25.1±3.3 kg/m2)。在50 kHz下,全身脚到手和直接节段BIA测量R, Xc和PhA。DXA作为参考。在三分之二的样本中,通过逐步回归建立了FFM的预测方程,并在其余三分之一的样本中进行了验证。使用Bland-Altman和Lin的一致性相关系数评估BIA技术与DXA的一致性。结果与直接节段BIA相比,脚-手BIA的R值较低(p < 0.001),而Xc和PhA值较高(p < 0.001)。尽管存在这些差异,但在不同设备的FFM估计中未观察到显著偏差(p > 0.05)。一致性分析显示一致性高,无系统偏差。从FFM得到的FM在群体水平上与DXA一致,但在个体水平上表现出系统的趋势。结论虽然不同技术的原始生物电参数不同,但在相同人群和参考方法中推导方程时,FFM估计值是可以比较的。然而,从FFM间接获得的FM在个体层面上缺乏准确性。

Background and aims
Fruits and sugar-sweetened beverages have opposing effects on cardiometabolic health, despite comparable amounts of fructose per serving. Here, we sought evidence for a role of the food matrix in modifying serum fructose dynamics and blood pressure.
Methods
We first performed multiple linear regression analyses to assess the association between energy-adjusted intake of fructose from different sources (total, fruit, fruit juice and sugar-sweetened beverages) and blood pressure (24-h ambulatory, 7-day ambulatory, and office) using data from The Maastricht Study, a large population-based cohort (n = 5,426–6,471). Next, we conducted a randomized crossover trial in which healthy individuals (n = 21) were exposed to a fixed amount of fructose (20g) from different matrices (apple, mashed apple, apple juice, and fructose dissolved in water), and measured the serum fructose and blood pressure response.
Results
The intake of fructose from sugar-sweetened beverages, but not from fruits or fruit juice, was associated with higher ambulatory 7-day mean blood pressure, higher office blood pressure, and greater risk of hypertension (OR: 1.29, 95%CI 1.12; 1.50 per 10g fructose). In the crossover study, pure fructose intake yielded the greatest serum fructose excursions (p < 0.05 for all comparisons). The systolic blood pressure response was higher after pure fructose compared to the other matrices (+1.8 mmHg, 95%CI 0.02; 3.5).
Conclusions
Here, we provide epidemiological and experimental evidence that highlights the relevance of the food matrix on fructose dynamics and blood pressure, independent of the caloric value of fructose.

Background and aims
Reduced brain vascular function contributes to age-related cognitive decline. While peanut consumption may improve cognitive performance, the underlying mechanisms remain unclear. This study aimed to investigate the longer-term effects of skin-roasted peanut consumption on brain vascular function and cognitive performance in older adults.
Methods
In a randomized, single-blind, controlled crossover trial, 31 healthy individuals (age [mean ± SD]: 67 ± 4 years; BMI: 26.7 ± 3.3 kg/m2) consumed 60 g/day of unsalted, skin-roasted peanuts or no peanuts (control) for 16 weeks, separated by an 8-week washout. During follow-up, brain vascular function was assessed by quantifying global cerebral blood flow (CBF) using arterial spin labeling magnetic resonance imaging, which was the primary outcome. Cognitive performance was evaluated using the Cambridge Neuropsychological Test Automated Battery (CANTAB).
Results
The consumption of peanuts was well-tolerated and median compliance was excellent: 100 % (interquartile range [IQR] 99–100 %). Compared with control, peanut consumption significantly increased global CBF by 3.6 % (intervention effect: 1.5 mL/100 g/min, 95 % CI [0.3, 2.6], p = 0.014) and gray matter CBF by 4.5 % (2.2 mL/100 g/min, 95 % CI [0.9, 3.6], p = 0.002). Verbal memory improved by 5.8 % during the delayed recall condition of the verbal recognition memory (VRM) task (+1.4 words correct (95 % CI [0.0, 2.7], p = 0.043). No beneficial effects were found in executive function and psychomotor speed outcomes. Systolic blood pressure (−5 mmHg; 95 % CI [-8, −2], p = 0.004) and pulse pressure (−4 mmHg; 95 % CI [-7, −1], p = 0.006) decreased during the peanut intervention.
Conclusions
Daily consumption of skin-roasted peanuts for 16 weeks improved brain vascular function in healthy older men and women. These favorable effects may underlie the observed improvements in verbal memory, highlighting a potential mechanism by which increased peanut intake beneficially affects cognitive performance.

In old adult patients with sarcopenia hospitalized for rehabilitation, the superior clinical benefit of a muscle-targeted formula (MTF; whey protein-based enriched with leucine and vitamin D) over an iso-caloric protein-free one was assessed through the IRIS trial (NCT03120026). The aim of this study is to further evaluate the economic benefit in the Italian context.
Methods
A cost-consequence secondary analysis was developed. Clinical inputs were evaluated over the course of the year in terms of nutrition cost, rehabilitation cost and modality of discharge (cost of staying at home vs institution) in three different payer perspectives: (1) hospital, including only nutrition and rehabilitation costs; (2) third-party payer (TPP), including also the economic consequences of patients discharged to an institution; and (3) societal perspective, including also the economic impact on families due to home assistance. For each one, the mean annual cost per patient was calculated. An estimation of the additional number of patients that could be hospitalized each year in Italy using the MTF was also computed.
Results
The MTF was less expensive in all three perspectives considered. Mean saving per patient by perspective was: hospital, € 1536; TPP, € 10,540; societal, € 14,363. Rehabilitation was faster in patients taking the MTF resulting in lower costs to manage sarcopenia, though savings were mostly driven by patients being discharged at home instead of an institution. Finally, assuming a use of the MTF ranging from 50 % to 80 %, about 495,214–792,342 bed days could be saved meaning that 10,538–18,067 additional patients may be treated every year.
Conclusions
Costs associated with the nutritional support of adult patients with sarcopenia hospitalized for rehabilitation with a MTF were inferior than an iso-caloric formula in all payer perspectives. Furthermore, LOS was shorter and more patients could be hospitalized with the same number of beds.

Objectives to background and aims
Obesity is a major global health challenge associated with increased risks of diabetes and cardiovascular disease. Although calorie restriction and exercise are cornerstone strategies for weight management, long-term adherence remains difficult in real-world settings. This randomised controlled trial aimed to evaluate the effectiveness of a structured calorie-restricted dietary therapy package combined with exercise in achieving weight loss and improving metabolic and psychological outcomes among obese adults.
Methods
In this 12-month, parallel-group randomised controlled trial, 99 obese adults were randomly assigned to an intervention group (standardised meal kit + exercise) or a control group (standard dietary advice + exercise). Weight, glucose, lipid profiles, and mental health outcomes were assessed at baseline, 3, 6, and 12 months. LASSO regression was used to identify predictors of successful weight loss, and linear mixed-effects models evaluated associations between percentage weight loss and changes in glycaemic, lipid, and psychosocial outcomes.
Results
By month 12, all participants in the intervention group achieved ≥5 % weight loss, with 59.18 % achieving ≥10 %, compared to 38.00 % and 6.00 % in the control group, respectively. Group assignment was the strongest predictor of weight loss success, followed by HDL levels and family history of obesity. Each 1 % reduction in body weight was significantly associated with lower FPG, 2hPG, TC, TG, and LDL-C, as well as improved SDS, SAS, and SF-36 scores. These associations remained significant after adjusting for confounders. However, interaction analyses showed no significant between-group differences in the effect of weight loss on outcomes.
Conclusion
A standardised dietary therapy package combining calorie restriction and exercise is a feasible and effective strategy to achieve clinically meaningful weight loss and improve metabolic and psychological health in obese adults. Although both groups experienced improvements, the structured intervention enhanced adherence and overall effectiveness.

Background
Dairy derived saturated and trans fatty acids may contribute to inverse associations of dairy intake with type 2 diabetes mellitus (T2DM) risk. Longitudinal studies examining this association are limited. This study investigated longitudinal associations of 15:0, trans-16:1n9, trans-18:1n11, and c9, trans-11 conjugated linoleic acid (CLA) in four serum fractions with insulin sensitivity, beta cell function and glucose concentrations.
Methods
Data were obtained from the Prospective Metabolism Islet Cell Evaluation (PROMISE) cohort (n = 418) from 4 separate evaluations over 9 years. Insulin sensitivity was assessed using Matsuda's insulin sensitivity index (ISI) and the homeostasis model assessment of insulin sensitivity (HOMA2_S). Beta cell function was determined using the insulinogenic index divided by HOMA insulin resistance (IGI/IR) and the Insulin Secretion-Sensitivity Index-2 (ISSI-2). Baseline serum fatty acids (mol%) were analyzed using gas chromatography flame-ionization detection. Longitudinal associations were analyzed using covariate-adjusted generalized estimating equations with false discovery adjusted P values.
Results
In the phospholipid (PL) pool, 15:0 was positively associated with logISSI2 (β = 6.54, CI: [2.84, 10.37], p < 0.01) and logIGI/IR (β = 14.75, CI: [6.92, 23.15], p < 0.01), and significantly inversely associated with logGlucose120 (β = −3.45, CI: [-5.63, −1.22], p < 0.05) and logGlucose Area Under the Curve (AUC) (β = −2.84, CI: [-4.38, −1.40], p < 0.01). Trans-16:1n9was significantly associated with logISI (β = 8.08, CI: [2.06, 14.45], p < 0.05) and inversely associated with logGlucose120 (β = −3.11, CI: [-5.50, −0.66], p < 0.05) and logGlucoseAUC (β = −2.16, CI: [-3.75, −0.55], p < 0.05).
Conclusions
Our findings extend the literature on the potential role of dairy derived saturated and trans conjugate fatty acids in cardiometabolic phenotypes underlying T2DM, specifically in the PL fraction.
