醛固酮与肥胖、代谢综合征(metabolic syndrome,MS)、炎症和血栓前状态有关;然而,大多数研究将这些指标与原发性醛固酮增多症(primary aldosteronism,PA)联系起来,排除了非PA的患者。本研究旨在确定在非PA人群中醛固酮、肾素或血浆醛固酮与肾素比值(plasma aldosterone to renin ratio,ARR)与代谢紊乱和炎症/血管生物标志物是否相关。方法:对275例患者(包括2种性别和青少年)进行血浆和尿醛固酮检测,并测定血浆肾素活性。在所有受试者中,MS的诊断根据美国国家胆固醇教育计划成人治疗组(adult treatment panel,ATP)第三次报告Ⅲ(ATPⅢ)来确定,并对代表肾脏、血管、炎症和盐皮质激素活性的生物标记物进行评估。

在407例新英格兰医学中心后循环登记患者中，59%为不伴TIA的卒中，24%在卒中前有TIA，16%仅表现为TIA。栓塞是最常见的卒中机制（占40%，其中24%为心源性栓塞，14%为动脉-动脉栓塞，2%两者兼有）。在32%的患者中，大动脉闭塞性损害导致血流动力学性脑缺血。梗死最常出现在后循环远段供血区（脑干腹侧、小脑上部以及枕叶和颞叶），近段（延髓和小脑后下部）和中段（桥脑和小脑前下部）供血区受累的比例相当。148例患者存在至少累及1支大动脉的重度闭塞性损害（狭窄〉50%），134例患者有单侧或双侧动脉受累。最常见的闭塞部位是椎动脉颅外段（52例患者，15例双侧）、椎动脉颅内段（40例患者，12例双侧）和基底动脉（46例患者）。动脉-动脉栓塞是椎动脉闭塞性疾病患者最常见的脑梗死发病机制。30d病死率为3.6%。发病机制为栓塞，远段供血区受累和基底动脉闭塞性疾病患者的预后最差。具有多处动脉狭窄部位的患者转归最好。他们通常经年累月地发生TIA。

目的确定感染人肠道病毒或腺病毒(均为常见的肠道病毒)是否可作为乳糜泻的预测因素。设计在挪威出生队列中纳入2001至2007年新生儿的巢式病例对照研究,随访至2016年9月。背景挪威人群。参与者携带HLA DR4-DQ8/DR3-DQ2基因型(增加患乳糜泻风险)的儿童。暴露因素采集3~36个月儿童每个月的粪便样本,并且用实时聚合酶链式反应检测其中的肠道病毒和腺病毒。主要结局测量根据乳糜泻的诊断标准诊断乳糜泻。分别在3,6,9和12个月时采集血样并检测乳糜泻抗体,之后每年检测一次。采用混合效应Logistic回归模型得到的调整后的比值比,来评估出现乳糜泻抗体前的病毒感染与乳糜泻之间的关系。结果在220名儿童中,平均9.9年(标准差为1.6)后,25名儿童在筛查后被诊断为乳糜泻,且每名患儿分别与两名对照组儿童进行配对。在2 135个样本中共有370个(17%)发现了肠道病毒,并且乳糜泻患者出现乳糜泻抗体前收集的样本肠道病毒阳性率显著高于对照组(调整后的比值比为1.49,95%可信区间为1.07-2.06;P=0.02)o这种关联仅限于引入鉄质后的感染。样本病毒拷贝数越多(>100 000拷贝/以)(调整后比值比为2.11,1.24-3.60;P=0.01)和长时间感染(>2个月)(2.16,1.16-4.04;P=0.02)具有更高的风险。通常检测到的肠道病毒A和肠道病毒B均与乳糜泻显著相关。在出现乳糜泻抗体期间或之后没有发现与感染的关联。腺病毒感染与乳糜泻无关。结论在这项纵向研究中,儿童早期肠道病毒的高检出率与后期乳糜泻的发生有关,而腺病毒的高检出率与乳糜泻无关。这个发现补充说明了病毒感染在乳糜泻病因学中的作用。

In this paper the Delaware Method published in 1963 is analyzed and upgraded with using correction factors which take into account the undesirable currents of the mean flow. However, this method presents graphically these correction factors which imply an impediment to fulfill the software calculations. Thus, the equations corresponding to the correction factor equations and a Fortran 77 numerical program were established. This system is given to explore different design alternatives in order to find the optimal solution to each proposed problem. The results of this work was a simple software that can perform calculations with the introduction of parameters depending only on the geometry of the heat exchanger, i.e., geometry, temperature and fluid characteristics eliminating the human errors and increasing the calculations speed and accuracy.
