Celiac disease (CD) is a chronic disease causing inflammation of the proximal small intestine that occurs in genetically predisposed individuals when they eat gluten which is a binding protein common in grains wheat, barley, and rye. The disease injury usually resolves when gluten is excluded from the diet. Although the injury will heal, the reaction to gluten is permanent and will recur with the reintroduction of gluten. The condition is surprisingly common, affecting as many as 1% of white populations. The consequences of the disease are predominantly those of malnutrition due to maldigestion and malabsorption, such as diarrhea, weight loss, and anemia. Symptoms caused by inflammation of the small intestine are also common. CD, although it is common and its pathology is well understood, frequently goes undiagnosed, probably because of the nonspecific or vague nature of many of the symptoms that occur. The cornerstone of treatment for CD is elimination of gluten from the diet. In most patients diagnosed with CD, a strict gluten‐free diet (GFD) alone should result in complete symptomatic and histologic resolution of the disease and reduce risk of complications. Noncompliance with diet is the leading cause of failure to respond in patients with CD. For these reasons, thorough assessment and counseling and management at the time of diagnosis and ongoing care are crucial. This article addresses the overview and diagnosis of CD and addresses its nutritional management in detail.
乳糜泻(CD)是一种引起小肠近端炎症的慢性疾病,在遗传易感个体中发生,当他们食用谷蛋白时,谷蛋白是小麦,大麦和黑麦中常见的一种结合蛋白。当饮食中不含麸质时,疾病损伤通常会消失。虽然损伤会愈合,但对谷蛋白的反应是永久性的,并且会随着谷蛋白的重新引入而复发。这种情况出奇地普遍,影响白人人口的比例高达1%。该病的后果主要是由消化不良和吸收不良引起的营养不良,如腹泻、体重减轻和贫血。由小肠炎症引起的症状也很常见。乳糜泻虽然很常见,其病理也很清楚,但常常未被诊断,可能是因为许多症状的非特异性或模糊性。乳糜泻治疗的基础是从饮食中剔除谷蛋白。在大多数被诊断为乳糜泻的患者中,严格的无麸质饮食(GFD)应该会导致疾病的完全症状和组织学解决,并降低并发症的风险。不遵守饮食习惯是导致乳糜泻患者治疗失败的主要原因。因此,在诊断和持续治疗时进行全面的评估、咨询和管理至关重要。本文介绍了乳糜泻的概况和诊断,并详细介绍了乳糜泻的营养管理。

The plasmid vector pET-28b(+) named “Young” was produced according a work of 2014 [1]. This construct is designed to allow the expression of a 13.6 kDA protein with a C-terminal 6histag. It is supposed to be an anti-HRP (Horse-radish peroxydase protein). This protein was not expressed in first E.coli: we attempt to explain this phenomenon.

Australian COVID-19 pandemic: A Bradford Hill Analysis of Iatrogenic Excess Mortality 澳大利亚COVID-19大流行:医源性超额死亡率的Bradford Hill分析
Pub Date : 2023-04-01 DOI: 10.33140/jcei.08.02.01
Australian official mortality data show no clear evidence of significant excess deaths in 2020, implying from an older WHO definition that there was no COVID-19 pandemic. A seasonality analysis suggests that COVID-19 deaths in 2020 were likely misclassifications of influenza and pneumonia deaths. Australian excess mortality became significant only since 2021 when the level was high enough to justify calling a pandemic. Significant excess mortality was strongly correlated (+74%) with COVID-19 mass injections five months earlier. Strength of correlation, consistency, specificity, temporality, and dose-response relationship are foremost Bradford Hill criteria which are satisfied by the data to suggest the iatrogenesis of the Australian pandemic, where excess deaths were largely caused by COVID-19 injections. Therefore, a strong case has been presented for the iatrogenic origins of the Australian COVID-19 pandemic and therefore, the associated mortality risk/benefit ratio for COVID injections is very high.
澳大利亚官方死亡率数据显示,2020年没有明显超额死亡的明确证据,这意味着根据世卫组织较早的定义,没有出现COVID-19大流行。一项季节性分析表明,2020年COVID-19死亡人数可能是对流感和肺炎死亡人数的错误分类。澳大利亚的超额死亡率直到2021年才变得显著,当时的水平高到足以证明是大流行。5个月前大量注射COVID-19与显著的超额死亡率(+74%)密切相关。相关性强度、一致性、特异性、时间性和剂量-反应关系是布拉德福德·希尔最重要的标准,数据满足了这些标准,表明澳大利亚大流行的医源性,其中过量死亡主要由COVID-19注射引起。因此,澳大利亚COVID-19大流行的医源性起源已经提出了强有力的案例,因此,COVID注射的相关死亡率风险/收益比非常高。

Chronic inflammation driven by proinflammatory cytokines (TNFα, IL-1β, IL-6, etc.), and nitric oxide (NO) plays an important role in the pathogenesis of several autoimmune, inflammatory as well as neurodegenerative disorders like rheumatoid arthritis, multiple sclerosis, Alzheimer's disease, Parkinson's disease, Huntington's disease, etc. Therefore, identification of nontoxic anti-inflammatory drugs may be beneficial for these autoimmune, inflammatory and neurodegenerative disorders. Cinnamein, an ester derivative of cinnamic acid and benzyl alcohol, is used as a flavoring agent and for its antifungal and antibacterial properties. This study underlines the importance of cinnamein in inhibiting the induction of proinflammatory molecules in RAW 264.7 macrophages and primary mouse microglia and astrocytes. Stimulation of RAW 264.7 macrophages with lipopolysaccharide (LPS) and interferon γ (IFNγ) led to marked production of NO. However, cinnamein pretreatment significantly inhibited LPS- and IFNγ-induced production of NO in RAW 264.7 macrophages. Cinnamein also reduced the mRNA expression of inducible nitric oxide synthase (iNOS) and TNFα in RAW cells. Accordingly, LPS and viral double-stranded RNA mimic polyinosinic: polycytidylic acid (polyIC) stimulated the production of TNFα, IL-1β and IL-6 in primary mouse microglia, which was inhibited by cinnamein pretreatment. Similarly, cinnamein also inhibited polyIC-induced production of TNFα and IL-6 in primary mouse astrocytes. These results suggest that cinnamein may be used to control inflammation in different autoimmune, inflammatory and neurodegenerative disorders.

由促炎细胞因子(TNFα、IL-1β、IL-6等)和一氧化氮(NO)驱动的慢性炎症在类风湿性关节炎、多发性硬化症、阿尔茨海默病、帕金森病、亨廷顿病等多种自身免疫性、炎性和神经退行性疾病的发病机制中起重要作用。因此,鉴定无毒抗炎药物可能对这些自身免疫性、炎症性和神经退行性疾病有益。肉桂素是肉桂酸和苯甲醇的酯衍生物,被用作调味剂,并具有抗真菌和抗菌性能。本研究强调了肉桂素在抑制RAW 264.7巨噬细胞和小鼠原代小胶质细胞和星形胶质细胞促炎分子诱导中的重要性。脂多糖(LPS)和干扰素γ (IFNγ)刺激RAW 264.7巨噬细胞导致NO的显著产生。然而,肉桂素预处理显著抑制LPS和ifn γ诱导的RAW 264.7巨噬细胞NO的产生。肉桂素还能降低RAW细胞诱导型一氧化氮合酶(iNOS)和TNFα mRNA的表达。因此,LPS和病毒双链RNA模拟多肌苷:多胞酸(polyIC)刺激小鼠原代小胶质细胞中TNFα、IL-1β和IL-6的产生,而肉桂蛋白预处理抑制了这些分泌。同样,肉桂素也能抑制多酚诱导的小鼠原代星形胶质细胞中TNFα和IL-6的产生。这些结果表明,肉桂蛋白可能用于控制不同的自身免疫、炎症和神经退行性疾病的炎症。

Effect of Food Allergy among Patients Affected by Delta and Omicron Variants-A Case Study Delta和Omicron变异对患者食物过敏的影响——一个案例研究
Pub Date : 2022-01-14 DOI: 10.33140/jcei.07.01.04
Background: The variants of SARS-CoV-2 have been affecting people globally since 2020. The Delta variant, mainly in India and the omicron variant in multiple countries since Nov 2021, has infected millions of people; many died out of them. Amongst all factors, food allergy is one factor that also accelerates many infected people’s comorbidities and overall health status during the pandemic. Aims: The study aimed to assess the role of some common food allergies in Delta and Omicron infected people in the Indian population. Methods: The study was designed with 50 covid positive home-isolated patients (out of 62) infected by both the mentioned variants from April 2021 until 15th January 2022. However, they were not severely ill but had comorbidities such as diabetes, obesity, hepatomegaly, etc. After the negative test result, each participant was requested to attend a telephonic interview for 15 minutes. Further, they were offered free online diet consultation considering the fatigue and some allergic symptoms. ATLAS-Ti-9 software was used for the fundamental analysis. Results: Based on their self-referred serological allergy test (SAT), we found that 23 samples of milk (46%), 14 (28%) samples of citrus fruits, 12 (24%) patients were allergic due to mustard oil and other detections too based on the positive interpretation (+ to +++) of specific IgE (IU/ml). The patients were facing type-1 hypersensitivity but no other severe allergic issues. Conclusions: Food allergy accelerated respiratory syndromes and comorbidities, mainly among the infected (Delta and Omicron) patients who could also have a high chance of hypersensitivity due to some common ingesting allergens.
背景:自2020年以来,SARS-CoV-2变体一直在全球范围内影响人类。自2021年11月以来,主要在印度和多个国家出现的Delta型和ommicron型已经感染了数百万人;许多人因此而死。在所有因素中,食物过敏是在大流行期间加速许多感染者的合并症和整体健康状况的一个因素。目的:本研究旨在评估一些常见食物过敏在印度三角洲和欧米克隆感染人群中的作用。方法:在2021年4月至2022年1月15日期间,该研究设计了50名covid阳性家庭隔离患者(来自62名患者),感染了上述两种变体。然而,他们的病情并不严重,但有合并症,如糖尿病、肥胖、肝肿大等。在测试结果为阴性后,每位参与者被要求参加15分钟的电话访谈。此外,考虑到疲劳和一些过敏症状,他们还获得了免费的在线饮食咨询。采用ATLAS-Ti-9软件进行基本分析。结果:基于自检血清过敏试验(SAT),我们发现牛奶23例(46%),柑橘类水果14例(28%),芥末油过敏12例(24%),其他检测也基于特异性IgE (IU/ml)阳性解释(+ ~ +++)。这些患者都有1型超敏反应,但没有其他严重的过敏问题。结论:食物过敏加速呼吸道综合征和合并症,主要发生在感染(Delta和Omicron)的患者中,由于摄入一些常见的过敏原,这些患者也有很高的机会发生超敏反应。

A Prayer from a Vegan Doctor 一个素食医生的祈祷

Lord please save us from the poor choices of food we pile on our plates. We are often unaware of how it determines our fate. With all the meat, fish, and eggs prepped with butter. Is it the saturated fat on our brains that blinds us to the fact that millions of animals suffer? We’re anxious, we’re angry, we have such low mood. Is it possible it’s because of our unhealthy food? “Oh no don’t take away my cheese, I’ll risk it all.” Those are the words from a victim of high cholesterol.
主啊,请拯救我们,让我们不要选择堆在盘子里的劣质食物。我们常常不知道它是如何决定我们的命运的。所有的肉、鱼和鸡蛋都涂上黄油。是我们大脑中的饱和脂肪让我们忽视了数百万动物正在遭受痛苦的事实吗?我们焦虑,我们生气,我们情绪低落。有没有可能是因为我们吃了不健康的食物?“哦,不,不要拿走我的奶酪,我会赌上一切的。”这是一位高胆固醇患者说的话。

Objective: The propose of study was to determine the viral load of Parvovirus B19 in children with proven acute lymphoblastic leukemia (ALL) Methods: A cross-sectional study designed in pediatric ward of Rasoul-e-Akram Hospital (educational, third referral) in Tehran, Iran (2015 – 2016). Sixty-nine children (mean age: 6.57 ± 4.25 years) in preservative phase of ALL selected. BMA had done, and the viral load for Parvovirus B19 determined by quantitative PCR. Results: Type of ALL was Pre B cell: 76.8%; Pro B cell: 14.5% and T-cell type: 7.8%. Low viral load determined in 18.8% (n=13); intermediate in 39.1% (n=27). High and very high viral load observed in 27.1% 15 (n=15) and 20.3% (n=1) of cases respectively. Viral load was related to Pro B cell type (p = 0.050) and lymphadenopathy (p = 0.040), but not related to gender (p = 0.350) and severity of ALL (p = 0.403); like hepatosplenomegaly, anemia, thrombocytopenia or need to transfusion. Conclusion: Parvovirus B19 is a common viral infection in young Iranian population. Near one-third of childbearing age, women in Iran are at risk for primary Parvovirus B19 infection. Here, to evaluate the possible role of parvovirus B19 Infection in the etiology of ALL, 42 % of ALL cases had high and very high viral load (21.7% and 20.3); the low or intermediate viral load is detectable in all cases. The viral load was related to Pro B cell type of ALL (p = 0.050) and the presence of lymphadenopathy. However, there is no relationship observed between Parvovirus B19 viral load and the severity of ALL and gender. It probably might be due to viral detection in the early stages of the ALL
目的:研究确定急性淋巴细胞白血病(ALL)患儿细小病毒B19的病毒载量。方法:在伊朗德黑兰Rasoul-e-Akram医院(教育,第三转诊)儿科病房进行横断面研究(2015 - 2016)。选择ALL保存期患儿69例(平均年龄:6.57±4.25岁)。B19细小病毒经BMA检测,定量PCR检测病毒载量。结果:ALL类型为Pre B细胞占76.8%;亲B细胞:14.5%,t细胞型:7.8%。18.8% (n=13)检测到低病毒载量;39.1%为中间体(n=27)。27.1%的15例(n=15)和20.3%的1例(n=1)的病例中存在高和极高的病毒载量。病毒载量与Pro B细胞类型(p = 0.050)和淋巴结病变(p = 0.040)相关,但与性别(p = 0.350)和ALL严重程度(p = 0.403)无关;如肝脾肿大、贫血、血小板减少或需要输血。结论:细小病毒B19是伊朗青年人群中常见的病毒感染。伊朗近三分之一的育龄妇女面临原发性细小病毒B19感染的风险。为了评估细小病毒B19感染在ALL病因学中的可能作用,42%的ALL病例具有高和非常高的病毒载量(21.7%和20.3%);在所有病例中均可检测到低或中等病毒载量。病毒载量与ALL的Pro B细胞类型(p = 0.050)和是否存在淋巴结病变有关。然而,细小病毒B19病毒载量与ALL的严重程度和性别之间没有关系。这可能是由于在ALL的早期阶段检测到病毒

This 73-year-old female patient has suffered from type 2 diabetes (T2D), hypertension, and hyperlipidemua for over 20 years. She started taking Metformin in 1999 and ceased taking it on 1/7/2019. As of 4/3/2019, her HbA1C level was at 6.6%. Since 4/4/2019, she implemented a lifestyle management program which not only focuses on diet and exercise but also factors in sleep, stress, life routines and habits, as well as environmental factors. In this article, the author applies the final conclusions from the American Diabetes Association (ADA) 2021 consensus report regarding “T2D Remission”. For this clinical case, he analyzes the patient’s present conditions to determine if she satisfies the criteria of “T2D remission” or not. The defined criteria of “remission” include timespan of at least one year, HbA1C level less than 6.5%, fasting plasma glucose (FPG) level less than 126 mg/dL, and estimated HbA1C (eA1C) values based on the mean continuous glucose monitoring (CGM) glucose data less than 6.5%. In conclusion, according to the ADA 2021 consensus report, this female patient is in “remission” for T2D. In summary, over the past year from 9/5/2020 to 9/5/2021, her average lab-A1C is 6.3%, mean CGM FPG value is 102 mg/dL, and CGM eAG is 5.7%. First, the selected one year satisfies the timespan requirement cited in the 2021 consensus report. Her set of glucose data has been collected over ~3 years, after post-Metformin (started on 1/7/2019) and her initiation of lifestyle management program that began on 4/4/2019. Second, all of her A1C values, both lab-tested and CGM eA1C, are less than 6.5% and her mean CGM FPG level is less than 126 mg/dL. Finally, she keeps a regular routine with quarterly medical examinations to monitor various diabetes complications, including macrovascular, micro- vascular, neural, and hormonal systems. The author understands and agrees with the consensus report that diabetes is non-curable and at most is “controllable” or “partially reversible”. Nevertheless, this female patient has also adopted a similar lifestyle improvement program as the author in order to deal with the root causes of her multiple metabolic disorders, particularly T2D, instead of suppressing the external symptoms of diabetes through medication intervention.
患者为女性,73岁,患有2型糖尿病(T2D)、高血压和高脂血症20多年。她于1999年开始服用二甲双胍,并于2019年1月7日停止服用。截至2019年4月3日,她的HbA1C水平为6.6%。自2019年4月4日起,她实施了一项生活方式管理计划,该计划不仅关注饮食和运动,还考虑了睡眠、压力、生活习惯和环境因素。在这篇文章中,作者引用了美国糖尿病协会(ADA) 2021年关于“t2dm缓解”的共识报告的最终结论。对于这个临床病例,他分析了患者目前的状况,以确定她是否满足“T2D缓解”的标准。“缓解”的定义标准包括时间跨度至少一年,HbA1C水平低于6.5%,空腹血糖(FPG)水平低于126 mg/dL,根据平均连续血糖监测(CGM)血糖数据估计的HbA1C (eA1C)值低于6.5%。总之,根据ADA 2021共识报告,该女性患者的T2D处于“缓解期”。综上所述,在过去的一年中,从2020年5月9日到2021年5月9日,她的平均实验室a1c为6.3%,平均CGM FPG值为102 mg/dL, CGM eAG为5.7%。首先,选择的一年符合2021年协商一致报告中提出的时间跨度要求。在服用二甲双胍后(2019年1月7日开始)和2019年4月4日开始的生活方式管理计划之后,她的血糖数据收集了大约3年。其次,她所有的A1C值,无论是实验室检测的还是CGM的eA1C,都小于6.5%,她的平均CGM FPG水平小于126 mg/dL。最后,她每季度定期体检,监测各种糖尿病并发症,包括大血管、微血管、神经系统和激素系统。作者理解并同意关于糖尿病是不可治愈的,最多是“可控”或“部分可逆”的共识报告。然而,该女性患者也采取了与作者类似的生活方式改善方案,以解决其多种代谢紊乱,特别是T2D的根本原因,而不是通过药物干预来抑制糖尿病的外部症状。
