The optimal protein dosage for neurocritical patients remains uncertain. We hypothesized that higher protein dosage increases azotemia risk and worsens prognosis, and that baseline BUN can guide protein dosage adjustments. In this single-center, retrospective cohort study, we included 327 neurocritical patients aged 18 or older admitted between July 2018 and June 2023 (BMI: 18.5-30 kg/m2). Daily protein intake from all sources was calculated. The primary outcome was azotemia incidence, and secondary outcomes included 30-day functional prognosis (mRS >3). Patients were categorized by protein intake: <0.8 g/kg/d, 0.8–1.3 g/kg/d, and >1.3 g/kg/d. Azotemia incidence was lower in the <0.8 g/kg/d group compared to the >1.3 g/kg/d group (21.9 vs. 45.7%, adjusted p = 0.002), with a significant correlation after adjusting for confounders. Among patients with an APACHE II score <15, the <0.8 g/kg/d group had lower azotemia rates and better prognosis. For those with a score ≥15, the >1.3 g/kg/d group had higher azotemia rates and worse prognosis. A U-shaped relationship between BUN and 30-day prognosis was observed in the <0.8 g/kg/d group. For BUN <4.3 mmol/L, protein intake of 0.8–1.3 g/kg/d improved outcomes, whereas for BUN >4.3 mmol/L, intake <0.8 g/kg/d was beneficial. The research demonstrates that excessive protein intake is associated with increased azotemia risk and worse outcomes. Baseline BUN may help inform protein dosage selection in neurocritical care, though its generalizability requires validation in multicenter prospective studies.

Skipping breakfast has been widely debated due to its potential health consequences across multiple domains. This systematic review evaluates literature from 2010 to 2025, analyzing 66 studies to assess its associations with obesity, diabetes, gut microbiome alterations, neurodegenerative diseases, cancer, sports performance, psychiatric disorders, cognitive health, and socioeconomic factors. The hypothesis suggests that breakfast omission is linked to various adverse health effects. Evidence highlights associations with obesity and weight gain due to altered hormonal responses influencing hunger and energy balance. Additionally, skipping breakfast negatively affects gut microbiota, contributing to systemic inflammation and metabolic dysfunction. Research suggests potential links to increased cancer risk through inflammatory pathways, while cognitive decline, mood disorders, and impaired athletic performance are also observed. Psychiatric disorders, including anxiety and depression, may be exacerbated by irregular meal patterns, influencing neurotransmitter regulation. Emerging studies indicate that breakfast consumption plays a role in bone mineral density, as prolonged fasting periods may affect calcium metabolism and skeletal health. Socioeconomic disparities impact breakfast consumption, affecting diet quality and overall health outcomes. While some individuals experience neutral or even beneficial effects, meal timing and caloric distribution play critical roles in metabolic and cardiovascular health. However, causality remains complex due to confounding factors like diet quality, physical activity, and socioeconomic status. Current studies face limitations, including small sample sizes and short intervention periods, requiring further research to refine conclusions and explore long-term mechanisms behind breakfast omission’s health impacts.

Breast cancer remains a leading global health challenge, with treatment resistance posing significant obstacles to effective therapy. Emerging research highlights the pivotal role of dietary polyunsaturated fatty acids (PUFAs) and gut microbiota in modulating breast cancer progression and therapeutic outcomes. This review explores the interplay and potential relevance of the PUFA–microbiota–ferroptosis axis in breast cancer progression and therapy. Omega-3 PUFAs, abundant in diets like the Mediterranean, exhibit anti-inflammatory properties, promote beneficial gut microbiota, and enhance ferroptosis, thereby reducing tumor proliferation and resistance. Conversely, omega-6 PUFAs, prevalent in Western diets, can exacerbate inflammation and tumor aggressiveness when imbalanced. Gut microbiota, through the production of short-chain fatty acids and PUFA-derived metabolites, further regulate ferroptosis sensitivity and systemic inflammation. We are evaluating the mechanisms by which omega-3 PUFAs and probiotics restore gut dysbiosis, modulate the tumor microenvironment, and synergize with treatments like chemotherapy and immune checkpoint inhibitors. Taken together and considering the generally favorable safety profile of omega-3 PUFAs, these findings suggest that the PUFA–microbiota–ferroptosis axis may represent a promising avenue for further investigation as a complementary strategy to address treatment resistance and improve outcomes. This warrants further translational research to optimize its clinical utility in personalized breast cancer management. Regulatory frameworks are also crucial to ensuring the safe and ethical implementation of PUFA-based interventions in global breast cancer care.

Metabolic syndrome (MetS) comprises a constellation of dysregulated cardiometabolic parameters. This study assessed associations between MetS and vitamin C in the US National Health and Nutrition Examination Survey (NHANES) to determine vitamin C requirements in people with a range of MetS severity, the hypothesis being that people with higher MetS severity would have higher requirements for the vitamin. Data for non-supplementing, fasting adults (n = 4,832) was extracted from NHANES 2003-6 and 2017-18 and included demographic and lifestyle variables, cardiometabolic laboratory variables, vitamin C dietary intakes and serum concentrations. MetS severity score was calculated using sex, waist circumference, systolic blood pressure, HDL cholesterol, triglycerides and fasting glucose concentrations. The mean (range) MetS severity score for the group was 0.19 (-4.0 to 6.8). There was a negative association between MetS severity score and serum vitamin C (r=-0.203, p < 0.001). Participants who met the vitamin C adequacy threshold of ≥50 µmol/L had a mean MetS severity score of 0.00 vs 0.38 in those who did not meet the threshold (p < 0.001). When the group was stratified by MetS severity score tertiles, the participants with the highest scores required an intake >100 mg/d, equating to an additional 65 mg/d (or 2.7-fold higher intake requirement) to meet the adequacy threshold relative to those with the lowest scores. Comparable relationships were observed between the individual MetS severity score components and vitamin C status and requirements. Overall, the results indicate that increased metabolic dysregulation results in decreased vitamin C status and a higher intake requirement for the vitamin to meet adequate circulating concentrations.
代谢综合征(MetS)包括一系列心脏代谢参数失调。这项研究在美国国家健康与营养调查(NHANES)中评估了MetS和维生素C之间的关系,以确定MetS严重程度人群的维生素C需求,假设MetS严重程度较高的人对维生素C的需求也较高。从NHANES 2003-6和2017-18中提取了未补充维生素C的空腹成年人(n = 4,832)的数据,包括人口统计学和生活方式变量、心脏代谢实验室变量、维生素C膳食摄入量和血清浓度。根据性别、腰围、收缩压、高密度脂蛋白胆固醇、甘油三酯和空腹血糖浓度计算MetS严重程度评分。该组MetS严重程度的平均(范围)评分为0.19(-4.0至6.8)。MetS严重程度评分与血清维生素C呈负相关(r=-0.203, p <;0.001)。达到维生素C充足阈值≥50µmol/L的参与者的平均MetS严重程度评分为0.00,而未达到阈值的参与者的平均MetS严重程度评分为0.38 (p <;0.001)。当按met严重程度评分分位数进行分组时,得分最高的参与者需要摄入100毫克/天,相当于额外的65毫克/天(或2.7倍的摄入量要求),以达到相对于得分最低的参与者的充足阈值。在个体MetS严重程度评分成分与维生素C状态和需求之间观察到可比较的关系。总的来说,结果表明,代谢失调的增加导致维生素C状态下降,维生素摄入量需要增加才能满足足够的循环浓度。

Obesity is a chronic multifactorial disease with associated harms and risks to health, as well as to quality of life and well-being. Currently, approximately 8% of the child and adolescent population suffer from obesity. The objective was to review psychoeducational interventions based on mindful eating for the prevention and management of obesity in youth. A review of the literature was conducted following a narrative approach with a review of different sources. Several databases were consulted (Web of Science [all databases], PsycINFO, Scopus). After searching for psychoeducational interventions based on mindful eating, a total of 15 articles were found, of which 10 were of a preventive nature in the normative child-adolescent population and the rest were aimed at the overweight or obese population or both conditions. The programs that trained mindful eating found behavioral improvements such as an increase in the choice and self-control in the consumption of food, in the identification of biological sensations, improvement in self-concept and well-being. In those interventions aimed at young people with obesity, improvements were obtained in aspects related to mindful eating, self-efficacy in weight control and food-related cravings, and in food control and the regulation of associated emotions. However, a great variety of weaknesses have been detected in the programs, such as the heterogeneity of applied models, use of measures, duration, sample size, lack of protocolization, control groups, or follow-up measures, among others. In conclusion, future lines of mindful eating-based interventions are proposed to extend the results by overcoming the limitations of the studies reviewed.
肥胖是一种慢性多因素疾病,对健康以及生活质量和福祉具有相关危害和风险。目前,大约8%的儿童和青少年患有肥胖症。目的是回顾以正念饮食为基础的心理教育干预措施对青少年肥胖的预防和管理。对文献的回顾是按照不同来源的回顾的叙述方法进行的。参考了几个数据库(Web of Science[所有数据库]、PsycINFO、Scopus)。在搜索了基于正念饮食的心理教育干预措施后,总共发现了15篇文章,其中10篇是针对正常儿童-青少年人群的预防性质,其余的针对超重或肥胖人群或两者兼而有之。训练正念饮食的项目发现了行为上的改善,比如在食物消费方面的选择和自我控制的增加,对生物感觉的识别,自我概念和幸福感的提高。在那些针对肥胖年轻人的干预措施中,在注意饮食、体重控制和食物相关渴望的自我效能、食物控制和相关情绪的调节等方面都得到了改善。然而,在项目中发现了各种各样的弱点,例如应用模型的异质性、度量的使用、持续时间、样本量、缺乏协议化、控制组或后续度量,等等。总之,未来的正念饮食为基础的干预建议线,以扩大结果,克服研究审查的局限性。

Vitamin E is a potent antioxidant with anti-inflammatory properties and has been proposed as a promising agent in mitigating conditions associated with metabolic syndrome (MetS). We hypothesize that vitamin E is inversely associated with inflammatory biomarkers and low-grade systemic inflammation while showing a direct association with anti-inflammatory biomarkers. Additionally, we hypothesize that vitamin E will also be inversely associated with the risk of developing MetS. This population-based, cross-sectional study used data from the 2015 ISA-Nutrition survey, which included 368 adults and 212 older adults residing in urban São Paulo. Plasma vitamin E concentration was measured using high-performance liquid chromatography, and MetS was diagnosed based on International Diabetes Federation criteria. Biochemical and anthropometric parameters were assessed using standardized protocols. Restricted cubic spline regression models were applied to evaluate nonlinear associations between vitamin E, inflammation, and MetS. In the linear association between IL-6 and vitamin E, there is an interaction with HDL-c. Our findings also revealed a nonlinear J-shaped association between vitamin E and hepcidin (P < .0001), IL-1β (P < .0001), and adiponectin (P < .001), as well as an inverse association with low-grade systemic inflammation (P < .05). Additionally, vitamin E demonstrated a nonlinear association with MetS (P < .01). These results suggest that vitamin E may play a protective role in modulating inflammation and MetS within this specific urban population. Understanding the interactions between vitamin E, inflammation, and MetS risk is essential for developing prevention and dietary management strategies. Future research should explore the underlying mechanisms and assess optimal vitamin E intake to support metabolic health.

Precision nutrition is emerging as a transformative strategy for optimizing health, particularly in the context of biological aging and chronic disease prevention. This review aims to examine how biological age markers—specifically telomere length and epigenetic clocks—can be integrated into precision nutrition frameworks to personalize interventions, enhance chronic disease management, and support healthy aging. Telomere length is a widely studied biomarker of aging and chronic disease risk, while epigenetic clocks, based on DNA methylation patterns, offer complementary insights into biological age, gene expression, and disease susceptibility. Nutritional interventions rich in antioxidants, omega-3 fatty acids, polyphenols, B vitamins, and anti-inflammatory compounds have shown potential to modulate these biomarkers, supporting cellular health and delaying aging processes. In addition, lifestyle factors such as physical activity, stress management, and adequate sleep play critical roles in maintaining telomere integrity and epigenetic stability. However, challenges remain in translating these biomarkers into clinical practice. Importantly, variability is not the only barrier; most of these biomarkers still lack clinical validation, and there is no consensus on standardized protocols or reference values that would support their routine application in healthcare. Current guidelines recommend combining telomere length and epigenetic age with other molecular markers, such as multi-omics data, within integrative biological age assessment approaches. Nevertheless, translating this approach into clinical practice will require overcoming significant limitations, including the validation of biomarkers, standardization of measurement techniques, cost-effectiveness, and the development of clear clinical guidelines. Continued research is essential to confirm their predictive value and practical utility in precision nutrition strategies aimed at promoting healthy aging and preventing chronic diseases.

Continued research is essential to confirm their predictive value and practical utility in precision nutrition strategies aimed at promoting healthy aging and preventing chronic diseases.</div></div>","PeriodicalId":19245,"journal":{"name":"Nutrition Research","volume":"140 ","pages":"Pages 135-160"},"PeriodicalIF":3.4,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Type 2 diabetes mellitus (T2DM) is a prevalent and multifactorial disease closely linked to overweight. Positive associations between body mass index (BMI) and dysfunctional eating behavior have been observed. However, research specifically examining eating behaviors among individuals with T2DM remains limited. We hypothesized that disordered eating behavior in this population is associated with poorer metabolic control. Thus, this study aimed to investigate the relationship between eating behavior patterns and metabolic control in outpatients with T2DM. In this cross-sectional study, the Three Factor Eating Questionnaire (TFEQ-R21) was administered to 238 outpatients with T2DM. BMI, glycemic control, blood lipids concentration, and blood pressure were examined as outcomes. Eating behavior patterns were identified through cluster analysis based on TFEQ-R21 dimensions. Linear regression models were used to investigate the associations between eating behavior patterns and outcomes, adjusting for age, sex, sedentary lifestyle, and psychiatric medication use. The study was approved by the Hospital's Ethics Committee (ID 2020-0654). Two eating behavior patterns were identified: cognitive restraint (n = 174) and emotional and uncontrolled eating behavior (n = 64). The emotional and uncontrolled eating behavior pattern was associated with higher BMI (b = 2.35; 95% CI = 0.68-4.01), HbA1c (b = 0.54; 95% CI = 0.06-1.01), and triglyceride values (b = 64.42; 95% CI = 16.99-111.86) after adjusting for confounders. In this sample of outpatients with T2DM, the emotional and uncontrolled eating behavior pattern was associated with higher BMI, HbA1c, and triglyceride values as compared to the cognitive restraint eating behavior pattern.
2型糖尿病(T2DM)是一种与超重密切相关的普遍多因素疾病。身体质量指数(BMI)与不正常饮食行为之间存在正相关。然而,专门研究2型糖尿病患者饮食行为的研究仍然有限。我们假设这一人群中饮食失调的行为与较差的代谢控制有关。因此,本研究旨在探讨门诊T2DM患者饮食行为模式与代谢控制之间的关系。在这项横断面研究中,对238例T2DM门诊患者进行了三因素饮食问卷(TFEQ-R21)。研究结果包括BMI、血糖控制、血脂浓度和血压。通过基于TFEQ-R21维度的聚类分析确定饮食行为模式。使用线性回归模型来调查饮食行为模式与结果之间的关系,调整年龄、性别、久坐的生活方式和精神药物的使用。该研究得到了医院伦理委员会(ID 2020-0654)的批准。确定了两种饮食行为模式:认知约束(n = 174)和情绪和不受控制的饮食行为(n = 64)。情绪化和不受控制的饮食行为模式与较高的BMI相关(b = 2.35;95% CI = 0.68-4.01), HbA1c (b = 0.54;95% CI = 0.06-1.01),甘油三酯值(b = 64.42;调整混杂因素后,95% CI = 16.99-111.86)。在该T2DM门诊患者样本中,与认知约束饮食行为模式相比,情绪性和不受控制的饮食行为模式与较高的BMI、HbA1c和甘油三酯值相关。

Functional hypothalamic amenorrhea (FHA) is a multifactorial condition caused by psychological stress, energy deficit, weight loss, and excessive physical activity in the absence of adequate energy intake. Nutrition plays a key role in FHA treatment, with the primary intervention focused on correcting energy imbalance. Evidence regarding the exact amount of energy required to restore menses, the timeframe for recovery, and the optimal nutritional practices to support long-term recovery and optimize reproductive outcomes, remain limited. In this review, we aimed to assess if dietary intervention affects the nutritional status, food intake, nutrition knowledge, and hormonal milieu in women with FHA. We performed this review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method, using the Population, Intervention, Control, Outcome, Study design criteria. A quality appraisal checklist for case series was used. The search included 4 databases and was restricted to English and Italian languages. Eleven articles were included. Five of these referred to the same population analyzed in 2 randomized controlled trials (RCTs); 3 nonrandomized controlled trials (NRCTs); and 1 nonrandomized uncontrolled trial, and 2 case series. Overall, the risk of bias was low for RCTs and moderate-to-high for NRCTs. Menstrual cycle can be restored in 1 to 12 months. One article indicated an additional 350 kcal/d energy intake to achieve this. However, the long-term impact of nutritional intervention alone remains unclear. Further research with a comprehensive, patient-centered approach is needed to confirm these findings and to clarify the possible role of nutritional counseling in FHA treatment.
