    在孟加拉国,营养不良和微量营养素缺乏如贫血被认为是重大的公共卫生挑战。增加鱼类消费是解决这些问题的完善的基于食物的干预措施。本文记录了基于社区的鱼辣酱生产的建立,并报告了其消费对孟加拉国农村150名孕妇和哺乳期妇女(PLW)中上臂围(MUAC)和血红蛋白(Hb)水平的影响。使用当地可用的成分开发了鱼酸辣酱,然后进行了一系列实验室测试,包括营养成分,保质期和食品安全。基于社区的鱼酸辣酱生产过程旨在:(1)提供当地可用的加工原料;(2)建立两个鱼干燥点;(3)启动基于社区的生产点;(4)由六名女性营养领域促进者将鱼酸辣酱分发给PLW,为期一年。然后,针对选定的150PLW设计了干预前后的研究,每天接受30克鱼酸辣酱,持续12个月。使用单向方差分析分析了消费前后平均MUAC和Hb水平的差异。食用30克鱼酸辣酱会导致目标PLW中Hb水平和MUAC的平均值显着增加。
    Undernutrition and micronutrient deficiencies such as anemia are considered significant public health challenges in Bangladesh, which enhancing fish consumption is a well-established food-based intervention to address these. This paper documents the establishment of community-based fish chutney production and reports the impact of its consumption on mid-upper arm circumference (MUAC) and hemoglobin (Hb) levels among targeted 150 pregnant and lactating women (PLW) in rural Bangladesh. A fish chutney was developed using locally available ingredients followed by a series of laboratory tests, including nutrient composition, shelf-life and food safety. A community-based fish chutney production process was designed to: (1) supply locally available ingredients for processing; (2) establish two fish drying sites; (3) initiate a community-based production site; and (4) distribute fish chutney to PLW for one year by six women nutrition field facilitators. Then a pre- and post-intervention study was designed for a selected 150 PLW to receive 30 g of fish chutney daily for 12 months. Differences in mean MUAC and Hb levels pre- and post-consumption were analyzed using one-way analysis of variance. Consumption of 30 g of fish-chutney resulted in significant increases of the mean values of Hb levels and MUAC among the targeted PLW.

    在一些国家,由于对母乳含量的需求和女性肝脏储备有限,哺乳期女性维生素A(VA)缺乏的风险增加。以前,食用三重强化大米,其中包括VA,铁,还有锌,成功改善了泰国儿童的VA状况,他们的全身VA存储(TBS)在2个月内翻了一番。
    这项研究评估了食用VA强化大米的功效,提供500微克视黄醇活性当量(RAE)/d,使用视黄醇同位素稀释(RID)测试对泰国哺乳期妇女的TBS和估计的总肝脏VA储备(TLRs)。
    对70名哺乳期妇女(n=35/组)进行了一项随机对照试验,这些妇女仅在工作日接受VA强化大米(500µgRAEs/d)或未强化大米14周。血清视黄醇浓度(SRs),C反应蛋白,和TBS在干预前后进行评估。配对13C-RID试验用于测量TBS。基线血液样本后,口服2.0μmol[14,15]-13C2-视黄酯乙酸酯。14d后抽取随访血样。干预后重复RID测试。
    干预组的TBS显着增加(P<0.05),从240(182,316)增加到331(251,447)[几何平均值(95%CIs)]µmol视黄醇,TBS的这种变化明显高于对照组[+52.9(-74,453)和-4.3(-106,275)µmol视黄醇](P<0.05)。估计的TLRs表明这些哺乳期妇女中VA缺乏症的患病率很高。初始和最终SRs在组间没有差异,并且在干预过程中没有变化。
    VA强化水稻通过增加TBS改善了哺乳期妇女的VA状况。在某些情况下,应考虑采取有针对性的方法在弱势群体中传播VA干预措施。该试验在clinicaltrials.gov注册为NCT03056625。
    Lactating women are at increased risk for vitamin A (VA) deficiency due to demands for breast milk content and limited hepatic stores for women in some countries. Previously, consumption of triple-fortified rice, which included VA, iron, and zinc, successfully improved the VA status of Thai children in whom their total body VA stores (TBSs) were doubled in 2 mo.
    This study assessed the efficacy of consuming VA-fortified rice, which delivered 500 µg retinol activity equivalents (RAEs)/d, on TBSs and estimated total liver VA reserves (TLRs) in Thai lactating women using the retinol isotope dilution (RID) test.
    A randomized controlled trial was conducted with 70 lactating women (n = 35/group) who received either VA-fortified rice (500 µg RAEs/d) or unfortified rice for 14 wk on weekdays only. Serum retinol concentrations (SRs), C-reactive protein, and TBSs were assessed before and after the intervention. The paired 13C-RID test was used to measure TBSs. After a baseline blood sample, 2.0 µmol [14,15]-13C2-retinyl acetate was administered orally. A follow-up blood sample was drawn 14 d later. The RID test was repeated after the intervention.
    TBSs increased significantly (P < 0.05) in the intervention group from 240 (182, 316) to 331 (251, 447) [geometric means (95% CIs)] µmol retinol, and this change in TBSs was significantly higher (P < 0.05) than that in the control group [+52.9 (-74, 453) compared with -4.3 (-106, 275) µmol retinol]. Estimated TLRs indicated a high prevalence of VA deficiency among these lactating women. Initial and final SRs did not differ by group and did not change over the course of the intervention.
    VA-fortified rice improved the VA status of lactating women by increasing TBSs. A targeted approach to disseminate VA interventions among vulnerable groups should be considered in some contexts. This trial was registered at clinicaltrials.gov as NCT03056625.

    目前针对乳腺癌患者的饮食指南(BCP)未能解决可以改善患者营养状况的大量和微量营养素的充足饮食摄入问题。这篇综述包括过去15年来自PubMed和BiomedCentral数据库的信息,涉及BCP的饮食指南和个性化的潜在影响,特定营养饮食对抗肿瘤治疗期间和之后患者营养状况的影响。结果表明,BCP应在诊断后立即接受营养评估。此外,应鼓励他们追求和保持健康的体重[体重指数(BMI;以kg/m2为单位)20-24.9],保持他们的瘦体重,避免增加脂肪量。因此,在营养状况诊断后,在适当的饮食干预中,可以考虑保守的能量限制为500-1000kcal/d。根据审查的信息,我们建议在抗肿瘤治疗期间和之后对BCP进行个性化营养干预。营养治疗的规范应基于患者的营养状况,饮食习惯,时间表,活动,文化偏好。BCP的每日能量摄入应分配如下:<30%脂肪/天(主要是单不饱和和多不饱和脂肪酸),55%的碳水化合物(主要是全食物,如燕麦,糙米,和水果),和1.2-1.5g蛋白质·kg-1·d-1,以避免节肢性肥胖。研究结果表明,应鼓励5-9份/d的水果(~150克/份)和蔬菜(~75克/份)。大蒜和十字花科蔬菜也必须是营养疗法的一部分。充足的膳食摄入以富含β-胡萝卜素和维生素A的食物为基础的大量和微量营养素,E,C和C都可以预防BCP的营养状况恶化,并改善其整体健康和预后。
    Current dietary guidelines for breast cancer patients (BCPs) fail to address adequate dietary intakes of macro- and micronutrients that may improve patients\' nutritional status. This review includes information from the PubMed and Biomed Central databases over the last 15 y concerning dietary guidelines for BCPs and the potential impact of a personalized, nutrient-specific diet on patients\' nutritional status during and after antineoplastic treatment. Results indicated that BCPs should receive a nutritional assessment immediately after diagnosis. In addition, they should be encouraged to pursue and maintain a healthy body weight [body mass index (BMI; in kg/m2) 20-24.9], preserving their lean mass and avoiding an increase in fat mass. Therefore, after nutritional status diagnosis, a conservative energy restriction of 500-1000 kcal/d could be considered in the dietary intervention when appropriate. Based on the reviewed information, we propose a personalized nutrition intervention for BCPs during and after antineoplastic treatment. Specifications in the nutritional therapy should be based on the patients\' nutritional status, dietary habits, schedule, activities, and cultural preferences. BCPs\' daily energy intake should be distributed as follows: <30% fat/d (mainly monounsaturated and polyunsaturated fatty acids), ∼55% carbohydrates (primarily whole foods such as oats, brown rice, and fruits), and 1.2-1.5 g protein ⋅ kg-1 ⋅ d-1 to avoid sarcopenic obesity. Findings suggest that 5-9 servings/d of fruits (∼150 g/serving) and vegetables (∼75 g/serving) should be encouraged. Garlic and cruciferous vegetables must also be part of the nutrition therapy. Adequate dietary intakes of food-based macro- and micronutrients rich in β-carotene and vitamins A, E, and C can both prevent deterioration in BCPs\' nutritional status and improve their overall health and prognosis.
