    塑料的广泛使用导致了各种尺寸的塑料废物的积累,特别是包括微塑料(MP)。将MPs引入水生生态系统可能导致生物体的污染,主要是鱼。这项研究首次对Gresik的乳鱼养殖池塘的水和沉积物中遇到的MPs的丰度进行了定量和定性分析,东爪哇,印度尼西亚。在2021年2月至4月之间在三个站点收集了水和沉积物样本。应用单因素方差分析和Pearson相关分析对MPs的丰度进行分析。结果确定了四种类型的MP:碎片,纤维,电影,和颗粒。3月观察到水(10.40颗粒/L)和沉积物样品(1.15颗粒/g)中MPs的最高丰度。水样中主要的MPs大小为100-500μm,而在沉积物中低于100μm。国会议员的颜色有八种不同的颜色:黑色,紫色,红色,蓝色,黄色,粉色,绿色,和透明。MPs聚合物的鉴定被发现是聚丙烯(PP),聚氨酯(PU),聚碳酸酯(PC),聚对苯二甲酸乙二醇酯(PETE),高密度聚乙烯(HDPE),和低密度聚乙烯(LDPE)。水柱和沉积物中MP的存在与池塘周围的人类活动有关。因此,大量的国会议员是污染的来源,有可能损害养殖奶鱼的营养质量。这项研究为地方政府制定更清洁的环境和改善人类健康的废物管理政策提供了重要信息。
    The widespread use of plastic has resulted in the accumulation of plastic waste across a range of sizes, notably including microplastics (MPs). The introduction of MPs into aquatic ecosystems can lead to the contamination of organisms, mainly fish. This study reports for the first time a quantitative and qualitative analysis conducted on the abundance of MPs encountered in water and sediment of milkfish aquaculture ponds in Gresik, East Java, Indonesia. Water and sediment samples were collected at three stations between February to April 2021. The abundance of MPs was analyzed through the application of one-way ANOVA tests and Pearson\'s correlation analysis. The results identified four types of MPs: fragments, fibers, films, and pellets. The highest abundance of MPs in both water (10.40 particle/L) and sediment samples (1.15 particle/g) was observed in March. The predominant MPs size in the water samples is 100-500 μm, while it is below 100 μm in the sediment. The color of the MPs varied across eight colors: black, purple, red, blue, yellow, pink, green, and transparent. The identification of MPs polymers was found to be polypropylene (PP), Polyurethane (PU), Polycarbonate (PC), Polyethylene terephthalate (PETE), High-density polyethylene (HDPE), and low-density polyethylene (LDPE). The presence of MPs in the water column and sediments was correlated with human activities around the ponds. Hence, the abundance of MPs is a source of pollution that has the potential to damage the nutritional quality of farmed milkfish. This study provides important information for the local governments to develop waste management policies for a cleaner environment and improved human health.

    谷物食品,包括早餐(BC)和婴儿谷物(IC),是最早介绍给婴儿的固体食物之一。BC和IC是对健康有益的宏观和微量营养素的来源,但也可能是有害的化学和微生物污染物和营养素的来源,这些污染物和营养素可能在高消费水平下导致不利的健康影响。这项研究是在RiskBenefit4EU项目下进行的,目的是评估35个月以下葡萄牙儿童食用BC和IC对健康的影响。与黄曲霉毒素的存在相关的副作用,蜡样芽孢杆菌,评估钠和游离糖对纤维摄入的益处.我们采用了风险收益评估方法,并量化了从当前到各种替代消费方案的BC和IC消费变化对健康的影响。根据残疾调整寿命年评估健康影响。结果表明,从当前的消费情景转向考虑的替代情景会导致健康生命年的增加。葡萄牙儿童可以从与BC交换IC的摄入量中受益,如果消耗的BC在纤维方面具有足够的营养特征,钠和游离糖,尽可能降低黄曲霉毒素的含量。
    Cereal-based foods, including breakfast (BC) and infant cereals (IC), are among the first solid foods introduced to infants. BC and IC are sources of macro and micronutrients that have beneficial effects on health, but can also be sources of harmful chemical and microbiological contaminants and nutrients that may lead to adverse health effects at high consumption levels. This study was performed under the RiskBenefit4EU project with the aim of assessing the health impact associated with consumption of BC and IC by Portuguese children under 35 months. Adverse effects associated with the presence of aflatoxins, Bacillus cereus, sodium and free sugars were assessed against the benefits of fiber intake. We applied a risk-benefit assessment approach, and quantified the health impact of changes in consumption of BC and IC from current to various alternative consumption scenarios. Health impact was assessed in terms of disability-adjusted life years. Results showed that moving from the current consumption scenario to considered alternative scenarios results in a gain of healthy life years. Portuguese children can benefit from exchanging intake of IC to BC, if the BC consumed has an adequate nutritional profile in terms of fiber, sodium and free sugars, with levels of aflatoxins reduced as much as possible.

    乳糜泻是在遗传易感个体中由麸质暴露引发的慢性自身免疫性疾病。其管理需要终身摄入无麸质(GF)饮食。小麦,黑麦和大麦在GF饮食中被淘汰,饮食的营养充足性受到质疑。在挪威,谷物和面包构成了饮食的关键作用,是纤维摄入的主要来源。因此,麸质限制可能对营养充足性提供重要影响,尤其是与乳糜泻患者的纤维摄入量有关。
    该研究的目的是调查GF产品的营养质量和价格,并与挪威市场上的含麸质产品进行比较。
    将423种独特的GF产品的大量营养素含量与337当量的面筋进行了比较。所有产品都是从杂货店和基于网络的商店中选择的,目的是包括尽可能多的GF产品。通过Wilcoxon符号秩检验,将11种不同食品类别中列出的大量营养素含量和价格与含麸质的对应物进行了比较。
    GF产品含有较少的蛋白质和纤维,和更高的饱和脂肪含量,与含麸质产品相比,碳水化合物和盐。两组之间的脂肪总量没有差异。在几种食物类别中发现了类似的模式。与GF产品相比,更多的含麸质产品符合“高纤维”(纤维>6g/100g)的营养要求。GF产品的价格更高;比含有麸质的产品贵46%-443%。
    GF产品与同等含麸质产品相比,营养较少,价格较高。知道不健康的饮食是发展非传染性疾病的最重要危险因素,GF饮食的营养质量需要解决,应该提高。
    UNASSIGNED: Celiac disease is a chronic autoimmune disease triggered by gluten exposure in genetically predisposed individuals. A life-long intake of a gluten-free (GF) diet is required for its management. Wheat, rye and barley are eliminated in a GF diet and the nutritional adequacy of the diet has been questioned. In Norway, cereals and bread constitute a key role of the diet and are the main source of fiber intake. Gluten restrictions may therefore offer important implications for nutrient adequacy especially linked to fiber intake in people with celiac disease.
    UNASSIGNED: The aim of the study was to investigate the nutritional quality and price of GF products and compare with gluten-containing counterparts available at instead of in the Norwegian market.
    UNASSIGNED: The macronutrient content of 423 unique GF products were compared with 337 equivalents with gluten. All products were selected from grocery stores and web-based shops, with the aim of including as many GF products as possible. Listed macronutrients content and price in 11 different food categories were compared to gluten-containing counterparts with Wilcoxon signed rank test.
    UNASSIGNED: The GF products contained less protein and fiber, and higher content of saturated fat, carbohydrate and salt compared to the gluten-containing products. The total amount of fat was not different between the groups. A similar pattern was found within several of the food categories. More gluten-containing products met the nutrition claim \"high in fiber\" (fiber > 6 g/100 g) compared to the GF products. The price of the GF products was higher; ranging from 46%-443% more expensive than the gluten-containing products.
    UNASSIGNED: GF products are less nutritious and have a higher price compared to equivalent gluten-containing products. Knowing that an unhealthy diet is the most important risk factor for developing non-communicable diseases, the nutritional quality of a GF diet needs to be addressed and should be improved.

    Primary care physicians frequently evaluate patients with constipation. The history is crucial in uncovering warning symptoms and signs that warrant colonoscopy. Particular elements in the history and rectal examination also can provide clues regarding the underlying etiology. Regardless of etiology, lifestyle modifications, fiber, and laxatives are first-line therapies. Patients who fail first-line therapies can be offered second-line treatments and/or referred for testing of defecatory function. In those with severely refractory symptoms, referrals to a gastroenterologist and a surgeon should be considered.

    一些研究表明,摄入高饮食血糖指数(GI)和血糖负荷(GL)与消化道癌症风险增加之间存在关联。我们假设GI和GL可能与伊朗高危人群的食管鳞状细胞癌(ESCC)风险相关。总的来说,我们采访了47例ESCC事件和96例频率匹配的医院对照,然后通过经过验证的食物频率问卷计算平均饮食GI和GL。膳食GL作为GI的函数计算,碳水化合物含量,以及某些食物的摄入频率。ESCC患者的饮食GI和GL水平明显高于对照组(P<0.05)。在调整了潜在的混杂因素后,饮食GI最高的人群与最低的人群相比,ESCC的风险高2.95倍(95%置信区间,1.68-3.35;趋势的P=.002)。此外,处于饮食GL的最高三分位数与ESCC风险呈正相关(比值比,3.49;95%置信区间,2.98-4.41;趋势的P=.001)。本研究的结果表明,高GI和GL的饮食可能对ESCC风险有潜在的不利影响,并提示过量循环胰岛素和相关的胰岛素样生长因子1在食管癌发展中可能发挥作用。
    Several studies have indicated the association between intake of foods high in dietary glycemic index (GI) and glycemic load (GL) with an increased risk of digestive tract cancers. We hypothesized that GI and GL may be associated with risk of esophageal squamous cell carcinoma (ESCC) in a high-risk population in Iran. In total, we interviewed 47 cases with incident of ESCC and 96 frequency-matched hospital controls, then calculated the average dietary GI and GL via a validated food frequency questionnaire. Dietary GL was calculated as a function of GI, carbohydrate content, and frequency of intake of certain foods. Dietary GI and GL levels were significantly higher among the ESCC cases compared with the controls (P < .05). After adjustment for potential confounders, those in the highest tertile of dietary GI had 2.95 times higher risk of ESCC compared with those in the lowest (95% confidence interval, 1.68-3.35; P for trend = .002). In addition, being in the highest tertile of dietary GL was positively associated with an ESCC risk (odds ratio, 3.49; 95% confidence interval, 2.98-4.41; P for trend = .001). Findings of the present study indicate that diets with high GI and GL might have potentially unfavorable effects on ESCC risk and suggest a possible role for excess circulating insulin and related insulin-like growth factor 1 in esophageal cancer development.
