    膳食纤维(DF)对于整体健康和疾病预防很重要。然而,西方国家的DF摄入量低于建议水平,主要是由于过度食用低纤维食品。强化主食,比如面包,使用膳食纤维成分是缩小我们饮食中纤维差距的一种方法。然而,将纯化和化学改性的纤维成分掺入食品中是具有挑战性的。这项研究揭示了可溶性可发酵(阿拉伯木聚糖)之间的相互作用,使用响应面法,不溶性可发酵(抗性淀粉IV型)和不溶性不可发酵(纤维素)纤维成分及其对面包质量的影响。这导致这些纤维成分的优化混合物可以共存于面包基质中,同时保持与白小麦面包相当的质量特性。与对照(不添加纤维)相比,用纤维成分部分替代面粉会干扰面筋网络,导致面筋强度降低12.4%,面筋网络发育时间延长24.4%。然而,面团发酵过程中的CO2保留系数不受纤维成分含量的影响。白面包的纤维含量增加了128%,对面包质量只有轻微的负面影响。此外,纤维强化面包在体外淀粉消化过程中显示出还原糖的释放较低。这项研究说明了面包系统中不同类型的纤维成分在缩小纤维间隙方面的协同作用。
    Dietary fibre (DF) is important for overall health and disease prevention. However, the intake of DF in Westernised countries is below the recommended level, largely due to the excessive consumption of low-fibre foods. Fortifying staple foods, such as bread, with dietary fibre ingredients is one approach to closing the fibre gap in our diet. However, incorporating purified and chemically modified fibre ingredients into food is challenging. This study unveils interactions between soluble-fermentable (arabinoxylan), insoluble-fermentable (resistant starch type IV) and insoluble-unfermentable (cellulose) fibre ingredients and their impact on bread quality using Response Surface Methodology. This resulted in an optimised mixture of these fibre ingredients that can coexist within a bread matrix while maintaining quality characteristics comparable to white wheat bread. The partial replacement of flour with fibre ingredients led to an interference with the gluten network causing a reduction in gluten strength by 12.4% and prolonged gluten network development time by 24.4% compared to the control (no fibre addition). However, the CO2 retention coefficient during dough fermentation was not affected by fibre ingredient inclusion. The fibre content of the white bread was increased by 128%, with only a marginal negative impact on bread quality. Additionally, the fibre-fortified bread showed a lower release of reducing sugars during in vitro starch digestion. This study illustrates the synergy of different types of fibre ingredients in a bread system to advance in closing the fibre gap.

    目的:早产儿代谢性骨病(MBDP)仍然是极早产儿发病的重要原因。在高危患者中,怀疑诊断和随后的治疗修改,在灵敏度和特异性方面有局限性,依赖低磷水平和/或高水平的碱性磷酸酶(ALP)。我们研究了成纤维细胞生长因子-23(FGF23)作为MBDP的早期标志物的潜力,当在有风险的患者中3-4周时进行测量时。
    方法:一项单中心前瞻性观察性非干预性研究,包括男女早产儿,胎龄小于32周和/或出生体重小于1500g。在营养概况中,在生命的3至4周之间进行的MBDP标准生化筛查中,FGF23的测定与其他临床和代谢研究一起纳入.这项研究是在桑坦德侯爵·德瓦尔德利亚大学医院进行的,西班牙,从2020年4月到2021年3月。参与者提供知情同意书。使用各种平台进行生化分析,随访评估由新生儿科医生自行决定.MBDP高危患者接受相应的治疗修改。样本进行了描述性分析,给出连续变量的集中趋势和分散的度量,以及类别数字的绝对数/百分比。使用的测试包括t检验,曼恩·惠特尼U测试,卡方检验,逻辑回归,皮尔逊相关性,和ROC曲线分析(IBMSPSSStatistics19版)。显著性水平:P<0.05。
    结果:在涉及25名高危早产儿的研究中,发现20%(n=5)被诊断为MBDP。根据3-4周龄的标准生化评估,这些患者中有3例(60%)被确定为高风险,而另外两名患者(40%)在随后的几周内被诊断出。然而,在所有5名患者中,FGF23水平的测量将允许在其他标志物改变之前早期识别和优化治疗。低水平的FGF23在3-4周,即使磷和ALP水平正常,表明需要修改营养补充剂。
    结论:MBDP仍然是极早产新生儿的一个重要问题。目前的诊断方法依赖于有限的生化标记。早期发现低FGF23水平可以及时干预,有可能避免去矿化。
    OBJECTIVE: Metabolic bone disease of prematurity (MBDP) remains a significant cause of morbidity in extremely premature newborns. In high-risk patients, suspected diagnosis and subsequent treatment modifications, with limitations in terms of sensitivity and specificity, rely on low phosphorus levels and/or high levels of alkaline phosphatase (ALP). We investigated the potential of fibroblast growth factor-23 (FGF23) as an early marker for MBDP when measured at 3-4 weeks of life in at-risk patients.
    METHODS: A single-center prospective observational non-interventional study including preterm newborns of both sexes, with a gestational age of less than 32 weeks and/or a birth weight of less than 1500 g. In the standard biochemical screening for MBDP performed between 3 and 4 weeks of life within a nutritional profile, the determination of FGF23 was included along with other clinical and metabolic studies. The study was conducted at Marqués de Valdecilla University Hospital in Santander, Spain, from April 2020 to March 2021. Participants provided informed consent. Biochemical analyses were conducted using various platforms, and follow-up evaluations were performed at the discretion of neonatologists. Patients at high risk for MBDP received modifications in treatment accordingly. The sample was descriptively analyzed, presenting measures of central tendency and dispersion for continuous variables, and absolute numbers/percentages for categorical ones. Tests used included t-tests, Mann‒Whitney U tests, chi-square tests, logistic regressions, Pearson correlation, and ROC curve analysis (IBM SPSS Statistics version 19). Significance level: P < 0.05.
    RESULTS: In the study involving 25 at-risk premature newborns, it was found that 20% (n = 5) were diagnosed with MBDP. Three of these patients (60%) were identified as high-risk based on standard biochemical evaluation at 3-4 weeks of age, while the other two patients (40%) were diagnosed in subsequent weeks. However, in all 5 patients, measurement of FGF23 levels would allow for early identification and optimization of treatment before other markers become altered. Low levels of FGF23 at 3-4 weeks, even with normal phosphorus and ALP levels, indicate the need for modifications in nutritional supplementation.
    CONCLUSIONS: MBDP remains a significant concern in extremely premature newborns. Current diagnostic methods rely on limited biochemical markers. Early detection of low FGF23 levels enables timely interventions, potentially averting demineralization.

    Millet products have garnered global recognition for their exceptional nutritional profile, appealing to various age demographics, and, therefore, fortifying such products with minerals can ensure nutritional security. This research explores the feasibility of utilizing millet as a substitute for refined wheat flour in biscuit production. Three distinct millet varieties were investigated: finger, pearl, and buckwheat. Employing response surface methodology (RSM), the optimal ratio of these flours was determined, resulting in a blend of 1.5:1:1, respectively. The optimized multi-millet biscuits were further enhanced with calcium fortification and subjected to comprehensive physico-chemical analysis. Proximate composition analysis revealed favorable levels of protein (5.472 ± 0.31%), ash (2.80 ± 0.57 g/100 g), and energy density (5.8015 ± 0.004 kcal/g), indicating a significantly higher protein content, enriched mineral profile, and high energy density as compared to refined wheat flour products. Sensory evaluation encompassing attributes such as color and texture and organoleptic assessment using a nine-point hedonic scale demonstrated favorable acceptance. Additionally, the overall acceptability of the biscuits remained consistently high throughout storage, ranging from 8.263 ± 0.65 (day 0) to 8.053 ± 0.85 (day 14). This study underscores the potential of multi-millet biscuits as a nutritious and palatable alternative to traditional wheat-based snacks, offering an avenue for diversifying dietary options and promoting healthier food choices.

    本研究旨在综合,表征,并评估了椰油酰胺丙基甜菜碱稳定的MnO2纳米颗粒(NPs)对豌豆幼苗萌发和发育的影响。合成的NP表现为50-600nm的聚集体,包括尺寸在19至50nm之间的球形颗粒。这些颗粒表现出部分结晶,由2θ=25.37、37.62、41.18、49.41、61.45和65.79°处的峰指示,MnO2的特征为具有I4/m空间群的四方晶格。量子化学模型表明,MnO2NPs与椰油酰胺丙基甜菜碱的稳定过程在能量上是有利的(ΔE>1299.000kcal/mol),并且在化学上是稳定的,正的化学硬度值(0.023≤η≤0.053eV)证实了这一点。揭示了MnO2分子与椰油酰胺丙基甜菜碱之间的相互作用,由仲氨基(NH)促进,是最可能的情况.这种确定得到了总能量(ΔE=1299.519kcal/mol)和化学硬度(η=0.053eV)的差值的支持。使用FTIR光谱进一步证实了这些发现。发现各种浓度的MnO2NPs对豌豆种子发芽的影响是非线性且模糊的。调查显示,浓度为0.1mg/L的MnO2NPs导致最高的发芽能量(91.25%),发芽性(95.60%),以及所有实验样品中根和幼苗的长度。然而,制剂浓度的增加导致轻微的生长抑制(1-10mg/L),并显着抑制幼苗和根系发育(100mg/L)。对豌豆幼苗的抗氧化指标和植物化学物质的分析表明,只有100mg/L的MnO2NPs对可溶性糖含量有负面影响,叶绿素a/b,类胡萝卜素,和酚类。相反,低浓度对光合作用指标有刺激作用。然而,所有浓度的MnO2NPs通常会降低豌豆幼苗的抗氧化潜力,ABTS参数除外。豌豆幼苗显示出显着的吸收锰的能力,在10mg/L时达到586.5μg/L,在100mg/L时达到892.6μg/L的MnO2NPs,根据科学文献,超过了豌豆的毒性水平。然而,最重要的结果是在用椰油酰胺丙基甜菜碱稳定的0.1mg/LMnO2NPs时观察到的生长刺激活性,为进一步研究提供了一个有希望的途径。
    This study aimed to synthesize, characterize, and evaluate the effect of cocamidopropyl betaine-stabilized MnO2 nanoparticles (NPs) on the germination and development of pea seedlings. The synthesized NPs manifested as aggregates ranging from 50-600 nm, comprising spherical particles sized between 19 to 50 nm. These particles exhibited partial crystallization, indicated by peaks at 2θ = 25.37, 37.62, 41.18, 49.41, 61.45, and 65.79°, characteristic of MnO2 with a tetragonal crystal lattice with a I4/m spatial group. Quantum chemical modelling showed that the stabilization process of MnO2 NPs with cocamidopropyl betaine is energetically advantageous (∆E > 1299.000 kcal/mol) and chemically stable, as confirmed by the positive chemical hardness values (0.023 ≤ η ≤ 0.053 eV). It was revealed that the interaction between the MnO2 molecule and cocamidopropyl betaine, facilitated by a secondary amino group (NH), is the most probable scenario. This ascertain is supported by the values of the difference in total energy (∆E = 1299.519 kcal/mol) and chemical hardness (η = 0.053 eV). These findings were further confirmed using FTIR spectroscopy. The effect of MnO2 NPs at various concentrations on the germination of pea seeds was found to be nonlinear and ambiguous. The investigation revealed that MnO2 NPs at a concentration of 0.1 mg/L resulted in the highest germination energy (91.25%), germinability (95.60%), and lengths of roots and seedlings among all experimental samples. However, an increase in the concentration of preparation led to a slight growth suppression (1-10 mg/L) and the pronounced inhibition of seedling and root development (100 mg/L). The analysis of antioxidant indicators and phytochemicals in pea seedlings indicated that only 100 mg/L MnO2 NPs have a negative effect on the content of soluble sugars, chlorophyll a/b, carotenoids, and phenols. Conversely, lower concentrations showed a stimulating effect on photosynthesis indicators. Nevertheless, MnO2 NPs at all concentrations generally decreased the antioxidant potential of pea seedlings, except for the ABTS parameter. Pea seedlings showed a notable capacity to absorb Mn, reaching levels of 586.5 μg/L at 10 mg/L and 892.6 μg/L at 100 mg/L MnO2 NPs, surpassing the toxic level for peas according to scientific literature. However, the most important result was the observed growth-stimulating activity at 0.1 mg/L MnO2 NPs stabilized with cocamidopropyl betaine, suggesting a promising avenue for further research.

    目的:模拟每100克面粉用200、400和500毫克钙强化小麦面粉对钙摄入有效性和安全性的影响。
    方法:使用IOWA摄入量模型对通过重复24小时饮食召回收集的横截面数据进行二次分析,评估和规划方案。
    方法:阿根廷国家健康和营养调查中的城市(ENNyS2018-2019)。
    方法:21358名参与者,包括孩子,青少年,和成年人。
    结果:所有年龄段的大多数人都报告食用小麦粉。在9岁以上的人群中,低钙摄入量的患病率超过80%。模拟每100克小麦粉500毫克钙的强化表明,在19岁至51岁以下的女孩和妇女以及4岁至71岁以下的男孩和男子中,低钙摄入量的患病率可以降低40个百分点以上,而在老年人中,低钙摄入量保持在65%以上。在所有年龄组中,高于上限摄入量的百分比仍低于1.5%。
    结论:可以进一步探索钙粉强化以提高钙摄入量。可以进行国家以下各级的模拟,以确定可以在阿根廷探索的这一战略可能无法达到的群体。该分析可用于倡导强化小麦粉的策略。
    OBJECTIVE: to simulate the impact on calcium intake- effectiveness and safety- of fortifying wheat flour with 200, 400 and 500 mg of calcium per 100 g of flour.
    METHODS: secondary analysis of cross-sectional data collected through repeated 24-hour dietary recalls using IOWA the Intake Modelling, Assessment and Planning Program.
    METHODS: urban cities in the National Health and Nutrition Survey of Argentina (ENNyS 2018 - 2019).
    METHODS: 21358 participants, including children, adolescents, and adults.
    RESULTS: Most individuals in all age groups reported consuming wheat flour. The prevalence of low calcium intake was above 80% in individuals older than 9 years. Simulating the fortification of 500 mg of calcium per 100 g of wheat flour showed that the prevalence of low calcium intake could be reduced by more than 40 percentage points in girls and women aged 19 to less than 51 and boys and men aged 4 to less than 71, while it remained above 65% in older ages. The percentages above the upper intake level remained below 1.5% in all age groups.
    CONCLUSIONS: Calcium flour fortification could be further explored to improve calcium intake. Subnational simulations could be performed to identify groups that might not be reached by this strategy that could be explored in Argentina. This analysis could be used to advocate for a strategy to fortify wheat flour.

    这项研究的目的是调查不同浓度(3%和6%)的两种成分(糊和面粉)的影响从价值的日期水果副产品对营养(近似组成和矿物质概况),工艺(凝血曲线,pH值,酸度,糖和有机酸含量和脱水收缩),物理化学(颜色,水活度和质地),山羊酸奶冷藏21天的微生物学和感官特性。两种成分都增强了酸奶发酵剂的生长和稳定性,从而提高添加日期的酸奶的益生菌潜力。物理化学,添加日期粉(在两个浓度)诱导更强的修改(质地,颜色和脱水收缩)在酸奶中比日期糊。储存期间,枣膏减少了脱水收缩,因此保持了酸奶的物理质量。消费者更喜欢用日期糊(3%和6%)而不是日期粉的酸奶,因为它的加入导致更多的棕色和颗粒状的质地。
    The aim of this study was to investigate the impact of different concentrations (3% and 6%) of two ingredients (paste and flour) obtained from the valorization of date fruit coproducts on the nutritional (proximate composition and mineral profile), technological (coagulation curve, pH, acidity, sugar and organic acid content and syneresis), physicochemical (color, water activity and texture), microbiological and sensory properties of goat\'s yogurt during 21 days of refrigerated storage. Both ingredients enhanced the growth and stability of the yogurt starter culture, thereby improving the probiotic potential of date-added yogurts. Physicochemically, the addition of date flour (at both concentrations) induces stronger modifications (texture, color and syneresis) in yogurts than the date paste. During storage, date paste reduced the syneresis and hence maintained yogurts\' physical quality. Consumers preferred the yogurts with date paste (3% and 6%) rather than with date flour, because its addition led to a more brownish color and granular texture.

    背景:对于极早产儿,人乳通常使用基于加工牛乳的配方产品进行强化。完整的牛初乳(BC),牛奶中含有丰富的抗炎因子,被认为是一种替代。我们调查了BC是否会影响早产儿的抗炎/TH2免疫和感染风险。
    方法:对于多中心的二次分析,随机对照试验(NCT03537365),极早产儿(妊娠26-31周,23%小于胎龄,SGA)随机接受BC(ColoDan,生物纤维,丹麦,n=113)或常规强化剂(PreNAN,雀巢,瑞士,n=116)。将感染定义为连续五天或更长时间的抗生素治疗,并在开始强化之前和之后在血浆中测量29种细胞因子/趋化因子。
    结果:一般来说,开始强化后的感染风险与低胎龄有关,强化前的SGA状态和抗生素使用情况。针对混杂因素进行了调整,强化BC的婴儿表现出更多的感染发作(20%vs12%,P<0.05)和更高的累积感染风险(危险比,HR1.9,P=0.06),特别是对于SGA婴儿(HR3.6,P<0.05)。此外,BC强化的婴儿有更高水平的TH2相关细胞因子/趋化因子(IL-10,MDC,MCP4)和与TH1/TH17应答(IL-15,IL-17,GM-CSF)相关的细胞因子水平降低。差异在SGA婴儿中最为明显,在BC组中显示出更高水平的TH2相关IL-4,IL-6和IL-13,而较低的干扰素-γ和IL-1α水平。
    结论:强化BC的婴儿表现出从TH2-到TH1-偏向的全身免疫的延迟转变,特别是在SGA婴儿中,可能受到多种混杂因素的影响,随着抗生素使用的增加,提示对感染的易感性增加。
    BACKGROUND: For very preterm infants, human milk is often fortified with formula products based on processed bovine milk. Intact bovine colostrum (BC), rich in anti-inflammatory milk factors, is considered an alternative. We investigated if BC affects anti-inflammatory/TH2 immunity and infection risk in very preterm infants.
    METHODS: For a secondary analysis of a multicenter, randomized controlled trial (NCT03537365), very preterm infants (26-31 weeks gestation, 23% small for gestational age, SGA) were randomized to receive BC (ColoDan, Biofiber, Denmark, n = 113) or conventional fortifier (PreNAN, Nestlé, Switzerland, n = 116). Infection was defined as antibiotic treatment for five or more consecutive days and 29 cytokines/chemokines were measured in plasma before and after start of fortification.
    RESULTS: In general, infection risk after start of fortification was associated with low gestational age, SGA status and antibiotics use prior to fortification. Adjusted for confounders, infants fortified with BC showed more infection episodes (20 vs 12%, P < 0.05) and higher cumulative infection risk (hazard ratio, HR 1.9, P = 0.06), particularly for SGA infants (HR 3.6, P < 0.05). Additionally, BC-fortified infants had higher levels of TH2-related cytokines/chemokines (IL-10, MDC, MCP4) and reduced levels of cytokines related to TH1/TH17-responses (IL-15, IL-17, GM-CSF). The differences were most pronounced in SGA infants, displaying higher levels of TH2-related IL-4, IL-6, and IL-13, and lower interferon-γ and IL-1α levels in the BC group.
    CONCLUSIONS: Infants fortified with BC displayed a delayed shift from TH2- to TH1-biased systemic immunity, notably in SGA infants, possibly influenced by multiple confounding factors, alongside elevated antibiotic use, suggesting increased susceptibility to infection.
