Background: Caffeine is a significant component of coffee, which is one of the most extensively, consumed non-alcoholic beverages. Caffeine is a methylxanthine-class central nervous system stimulant that is one of the most extensively utilized medications on the planet. Caffeine stimulates the central nervous system and is perhaps the most extensively used psychoactive stimulant. It causes gastrointestinal disturbances, tremor, headache, and sleeplessness, palpitations, cardiac arrhythmias, and it has been proposed that caffeine is possibly hypertensive. Aim: The goal of the study was to see how caffeine affected the blood pressure of Sudanese adult females in Gezira state's east during July and August 2018. Methods: A descriptive cross-sectional prospective study of 400 females aged 18 to 70 years old from various areas of Gezira State was conducted. Caffeine was not consumed by the participants for 12 hours before to the test. Blood pressure was monitored at baseline after 20 minutes of rest, then 45 minutes later after consuming a 150 mL cup of boiling coffee (120 mg caffeine) (each cup contain teaspoon 10 g of coffee powder). A questionnaire was created to collect personal and demographic information. Body mass index (BMI) was computed after measuring weight and height. Results: The researchers discovered that 120 mg of caffeine increased systolic blood pressure by 5 to 18 mmHg, diastolic blood pressure by 6 to 16 mmHg, and mean blood pressure by 3 to 13 mmHg. Caffeine had a higher effect in older and hypertensive people, according to the study, with a P value of <0.0001. With regular coffee consumption, there was no tolerance to the pressure impact of caffeine, according to the study. There was also racial variance in the caffeine presser response, with the Tama tribe having a stronger response and the Rufaah tribe having a higher baseline BP (P value is <0.0001). In addition, the prevalence of hypertension was 5.8% lower in rural areas. Conclusion: Caffeine raises systolic, diastolic, and mean blood pressure in Sudanese adult females, with a particularly noticeable effect on the elderly and hypertensive.
背景:咖啡因是咖啡的重要成分,而咖啡是消费最广泛的非酒精饮料之一。咖啡因是一种甲基黄嘌呤类中枢神经系统兴奋剂,是地球上使用最广泛的药物之一。咖啡因刺激中枢神经系统,可能是最广泛使用的精神兴奋剂。它会引起胃肠道紊乱、震颤、头痛、失眠、心悸、心律失常,而且有人提出咖啡因可能会导致高血压。目的:该研究的目的是了解咖啡因在2018年7月至8月期间如何影响格齐拉州东部苏丹成年女性的血压。方法:对来自Gezira州不同地区的400名年龄在18至70岁之间的女性进行描述性横断面前瞻性研究。在测试前的12小时内,参与者没有摄入咖啡因。在休息20分钟后监测血压,然后在45分钟后饮用一杯150毫升的沸腾咖啡(120毫克咖啡因)(每杯含有一茶匙10克咖啡粉)。制作了一份调查问卷来收集个人和人口统计信息。测量体重和身高后计算身体质量指数(BMI)。结果:研究人员发现,120毫克的咖啡因使收缩压增加5到18毫米汞柱,舒张压增加6到16毫米汞柱,平均血压增加3到13毫米汞柱。根据这项研究,咖啡因对老年人和高血压患者的影响更大,P值<0.0001。根据这项研究,经常喝咖啡的人对咖啡因的压力影响没有耐受性。咖啡因加压反应也存在种族差异,Tama部落的反应更强,Rufaah部落的基线血压更高(P值<0.0001)。此外,农村地区的高血压患病率低5.8%。结论:咖啡因提高苏丹成年女性的收缩压、舒张压和平均血压,对老年人和高血压患者的影响尤为明显。

The microbiota can be defined as the community of microorganisms that live in a particular environment and as we all know, different types of microbes colonized the human body, derived from bacterial communities, microbial eukaryotes and viruses that are specific for each anatomical sites or environments. The next- generation DNA sequencing has allowed more and more advanced sampling and analysis of these complex systems by methods called culture- independent, these methods are indicating the differences in community structure between individuals, between diseased states and healthy and between anatomical sites. The advent of next generation sequencing (NGS) offered a cost-effective method that eliminated the cloning step by amplifying 16S rRNA genes using primers containing sequencing connecters and barcodes. However, this sequencing may not resolve closely related species at all times and probably miss the intra-species diversity. A shotgun sequencing was developed for direct sequencing of DNA. Metagenomics is the practice of sequencing DNA from the genomes of all organisms present in a particular sample, and has become a common method for the study of microbiota population structure and function. As sequencing-based microbiota analysis continues to be the greatest general technique across the arena, this review aim is to provide a general introduction to the technical opportunities and trials of sequence-based identification of human associated Microbiota and for understanding of the human Microbiota and their effect on human health and diseases.
微生物群可以定义为生活在特定环境中的微生物群落,我们都知道,不同类型的微生物在人体中定植,来自细菌群落,微生物真核生物和病毒,它们对每个解剖部位或环境都是特定的。下一代DNA测序已经允许越来越先进的采样和分析这些复杂的系统的方法被称为培养无关,这些方法表明在个体之间的群落结构的差异,患病状态和健康之间,以及解剖部位之间。下一代测序(NGS)的出现提供了一种低成本的方法,通过使用含有测序连接器和条形码的引物来扩增16S rRNA基因,从而消除了克隆步骤。然而,这种测序可能无法始终解决近亲物种,并且可能错过物种内多样性。采用散弹枪测序法对DNA进行直接测序。宏基因组学是从特定样品中存在的所有生物体的基因组中测序DNA的实践,并已成为研究微生物群结构和功能的常用方法。由于基于测序的微生物群分析仍然是整个领域最重要的通用技术,本综述的目的是提供基于序列的人类相关微生物群鉴定的技术机会和试验的一般介绍,并了解人类微生物群及其对人类健康和疾病的影响。

Background: Interleukin-1 considered as a cytokine type multifunction and it is a feature that causes inflammation. Aim and Objective: to detect and study the immunological and molecular affect of Interleukin-1 α (IL-1 α) in Iraqi Women with Polycystic Ovarian Syndrome. Materials and Methods: 250 Iraqi women, their ages were from 15 to 50 years, they were divided into two groups: study group (n=125, Polycystic Ovary Syndrome PCOS) while the other group (n=125 control group mainly normal women), blood samples were taken in the second menstruate cycle day, the concentration of IL-1 α was calculated for each group, and after this determine the IL-1 α SNP (IL-1 α Rs1800787 A/G) by using real time PCR. Results: PCSO patients show a noticeable difference compared with other group. The mean level of IL-1α was 69.69± 93.38 (Pg /ml), 3.52E2± 139.15 (Pg /ml) in PCOS and healthy control respectively. The levels were ranging between 0 and 591 Pg/ml. The GG genotype (mutant gene) was detected in 94/125 (75.2%) of PCOS, and the AG genotype was detected in 31/125 (24.8%) of PCOS. The AA genotype (wild type) was not detected in both healthy and PCOS groups. Conclusions: The results showed high significant association of G allele in IL-1 α Rs1800787 A/G gene SNP (A/G) with PCOS, (P<0.0001), this increasing may related to ovulation lack, while the polymorphism in IL-1 α, can be a predispose aspect for the PCOS weakness.
背景:白细胞介素-1被认为是一种多功能的细胞因子,是引起炎症的一个特征。目的和目的:检测和研究白细胞介素-1 α (IL-1 α)在伊拉克多囊卵巢综合征妇女中的免疫学和分子作用。材料与方法:250名年龄在15 ~ 50岁的伊拉克妇女,将其分为两组:研究组(n=125,多囊卵巢综合征)和对照组(n=125,以正常女性为主要对照组),于月经周期第2天采血,计算各组IL-1 α浓度,并采用实时荧光定量PCR法测定IL-1 α SNP (IL-1 α Rs1800787 A/G)。结果:PCSO患者与其他组比较有显著性差异。PCOS组和健康对照组IL-1α平均水平分别为69.69±93.38 (Pg /ml)、3.52E2±139.15 (Pg /ml)。水平在0到591 Pg/ml之间。94/125 (75.2%) PCOS患者检测到GG基因型,31/125 (24.8%)PCOS患者检测到AG基因型。健康组和PCOS组均未检测到AA基因型(野生型)。结论:IL-1 α Rs1800787 A/G基因SNP (A/G)等位基因G与PCOS有高度相关性(P<0.0001),这种增高可能与排卵不足有关,而IL-1 α多态性可能是PCOS虚弱的易感因素。

The normal human skin is colonized by huge numbers of bacteria that live as commensals on its surface. At times bacteria not normally found there may colonize the epidermis and lead rapidly to disease. The oral cavity is comprised of many surfaces, each coated with a plethora of bacteria, the proverbial bacterial biofilm. Some of these bacteria have been implicated in oral diseases such as caries and periodontitis, which are among the most common bacterial infections in humans. In addition, specific oral bacterial species have been implicated in several systemic diseases, such as bacterial endocarditis, aspiration pneumonia, osteomyelitis in children, preterm low birth weight, and cardiovascular disease. The aim of this study is to evaluate the bacteria species associated with the skin and orals of different occupational groups in Ekpoma. This study was carried out in the Ekpoma, Esan West Local Government Area of Edo State. Participants were selected from the list of five (5) different occupational groups (Students, Office workers, Bike riders, Food handlers and Brick layers) in Ekpoma. Informed consent was sought from the various individuals. A total of one hundred (100) samples were collected from different occupational groups in the study area. The sample analysis was carried out using standard methods. Results obtained showed the rate of bacterial isolates from the skin and orals of the occupational groups studied is 63% and 43% respectively. Out of the 20 samples collected from the skin of each occupations, 9(45%) were positive for students, 16(80%) were for bike riders, 8(40%) for office workers, 17(85%) were for food handlers and 13(33%) for bricklayers. Food handlers appeared to be the occupation with the highest bacterial isolates on the skin followed by bike riders, bricklayers, students and office workers being the least. While out of the 20 samples collected from the mouth of each occupations, 7(35%) were positive for students, 11(55%) were for bike riders, 4(20%) for office workers, 12(60%) were for food handlers and 9(45%) for bricklayers. Office workers the highest bacteria isolates in the mouth followed by bike riders, food handlers and students been the least. In order to meet the huge challenge of occupational safety in the 21st century, a coordinative and cooperative approach is required. This will be a major task of the public health community and will require the use of new methods of identifying, monitoring and assessing of skin and oral infections, including the wide application of the hazard analysis and critical control point system.
正常的人类皮肤上寄生着大量的细菌,它们以共生的方式生活在皮肤表面。有时不常见的细菌会在表皮上定植,并迅速导致疾病。口腔由许多表面组成,每个表面都覆盖着大量的细菌,即众所周知的细菌生物膜。其中一些细菌与口腔疾病有关,如龋齿和牙周炎,这是人类最常见的细菌感染。此外,特定的口腔细菌种类与一些全身性疾病有关,如细菌性心内膜炎、吸入性肺炎、儿童骨髓炎、早产低出生体重和心血管疾病。本研究的目的是评估Ekpoma不同职业人群皮肤和口腔相关细菌种类。这项研究是在江户州Esan West地方政府区Ekpoma进行的。参与者从Ekpoma的五(5)个不同职业群体(学生、办公室职员、骑自行车的人、食品处理人员和砌砖工人)中选出。征求了不同个人的知情同意。从研究区域的不同职业群体中共收集了一百(100)个样本。样品分析采用标准方法进行。结果表明,职业人群皮肤和口腔细菌分离率分别为63%和43%。从每个职业收集的20个皮肤样本中,学生9个(45%)呈阳性,自行车手16个(80%),办公室工作人员8个(40%),食品处理人员17个(85%),瓦匠13个(33%)。食品加工人员皮肤上细菌分离率最高,其次是骑自行车的人、瓦匠、学生和办公室职员。在从每个职业的口收集的20个样本中,学生7个(35%)为阳性,自行车手11个(55%),办公室工作人员4个(20%),食品处理人员12个(60%),瓦匠9个(45%)。办公室职员的口腔细菌含量最高,其次是骑自行车的人、食品加工人员和学生。为了迎接21世纪职业安全的巨大挑战,需要采取协调合作的方式。这将是公共卫生界的一项主要任务,需要使用新的方法来查明、监测和评估皮肤和口腔感染,包括广泛应用危害分析和关键控制点系统。

The study investigated the effect of Adansonia digitata and garlic on Blood glucose level in streptozotocin induced diabetic rats. Twenty (20) albino rats were divided into four groups (GI, II, III, and IV) of five rats each and their fasting blood glucose was noted prior to inducement with diabetes using streptozotocin (STZ) at dose of 50mg/kg body weight. GI serves as diabetic control, receives no extract, while GII, GIII and GIV were respectively administered with 500mg/Kg Adansonia digitata extract, 400mg/Kg garlic extract and 500mg/Kg Adansonia – Garlic premix orally for 12 days. The serum blood glucose was monitored at interval of three days, after which the rats were allowed for nine days without extract with periodic record of their blood glucose at interval of three days. The fasting blood glucose in each group 24 hours after streptozotocin (STZ) injection was significantly higher (P<0.05) when compared Zero hours (before induction). The periodic Blood glucose levels were significantly lower (P<0.001) in the Group treated with 500mg/kg of Adansonia digitata, 400mg/kg of garlic and 500mg/kg of the premix extract compared to the corresponding period of GI. On withdrawal of the extracts, blood glucose of the diabetics rats increase. It may be concluded that both Adansonia digitata and garlic may possess hypoglycemic activity which could be due to their phytochemical and mineral contents.
本研究探讨了牡丹、大蒜对链脲佐菌素诱导的糖尿病大鼠血糖水平的影响。将20只白化大鼠分为4组(GI、II、III、IV),每组5只,用50mg/kg体重的链脲佐菌素(STZ)诱导糖尿病前记录空腹血糖。GI组作为糖尿病对照组,不给予提取物,GII组、GIII组和GIV组分别给予500mg/Kg adanonia digitata提取物、400mg/Kg大蒜提取物和500mg/Kg adanonia - garlic预混料,口服12 d。每隔3天监测一次血清血糖,之后连续9天不提取,每隔3天定期记录一次血糖。各组小鼠注射STZ后24 h空腹血糖较诱导前0 h显著升高(P<0.05)。与GI相应时期相比,500mg/kg Adansonia、400mg/kg大蒜和500mg/kg预混提取物组的周期血糖水平显著降低(P<0.001)。停药后,糖尿病大鼠血糖升高。由此可见,大蒜和牡丹均具有降血糖作用,这可能与它们的植物化学和矿物质含量有关。

Kawasaki disease (KD), also known as Kawasaki syndrome, is an acute febrile illness of unknown cause that primarily affects children younger than 5 years of age. The present study was conducted to study the clinical profile and outcome and risk factors of Kawasaki disease in children. This observational prospective study was conducted in cardiology ward with a diagnosis of Kawasaki disease from 1st June 2020 to 31 July 2021 in Bangabandhu Sheikh Mujib Medical University Hospital Dhaka, Bangladesh. Forty five (45) children aged between 3 months to 10 years were studied. Kawasaki disease is more prevalent among male child (73.33%). Most commonly encountered risk factor for cardiovascular involvement especially coronary dilatation or aneurysmal change is more observed in younger age of presentation. Fever, rash, conjunctivitis, erythema and edema of limbs, periungual skin desquamations are the presenting features. Cardiovascular involvement of left main coronary artery dilation is the most frequently observed aneurismal change observed among study population which was evident in 68% of the children having coronary involvement. All the study patient received high dose aspirin (100%) and 93% received IVIG of whom 6.66% had IVIG- resistant Kawasaki disease. Commonly occurring complication is uveitis (17.77%). Among the total 45 study population 1 patient expired (2.22%).Clinicians should have a high index of suspicion of Kawasaki disease in persistently febrile patients and once clinically diagnosed, echocardiography should be done and IVIG therapy along with aspirin should be started, specially in infants (<6 months) as they have the higher tendency to develop coronary aneurysm.
川崎病(KD),又称川崎综合征,是一种病因不明的急性发热性疾病,主要影响5岁以下儿童。本研究旨在探讨儿童川崎病的临床特点、预后及危险因素。这项观察性前瞻性研究于2020年6月1日至2021年7月31日在孟加拉国达卡Bangabandhu Sheikh Mujib医科大学医院诊断为川崎病的心脏病病房进行。研究对象为45名年龄在3个月至10岁之间的儿童。川崎病以男童多见(73.33%)。最常见的心血管累及危险因素,特别是冠状动脉扩张或动脉瘤改变,在年轻时更容易观察到。发热、皮疹、结膜炎、四肢红斑水肿、趾周皮肤脱屑是主要表现。左主干冠状动脉扩张累及心血管是研究人群中最常见的动脉瘤改变,68%的儿童有冠状动脉累及。所有患者均接受大剂量阿司匹林治疗(100%),93%的患者接受IVIG治疗,其中6.66%的患者存在IVIG抵抗性川崎病。常见的并发症是葡萄膜炎(17.77%)。在45例研究人群中,1例患者死亡(2.22%)。临床医生对持续发热患者应高度怀疑川崎病,一旦临床确诊,应进行超声心动图检查,并开始IVIG联合阿司匹林治疗,特别是婴儿(<6个月),因为他们更容易发生冠状动脉瘤。
