9月1日,一项发表在国际杂志Lancet Infectious Diseases上的研究报告中,来自瑞士的科学家通过研究开发了一种新型可靠的、针对儿童的高特异性的肺结核血液检测技术;这种新型的名为TAM-TB实验的检测技术是第一个可以用于检测阳性肺结核儿童的可靠免疫诊断法,其具有较高的特异性,可以对儿童是否患肺结核进行快测检测。

儿童患肺结核是全球一项比较严重的健康问题,尤其是在资源较为缺乏的国家里,全球每年大约有100万儿童会患上肺结核,但不幸的是,针对儿童的肺结核诊断手段却未能及时开发出来。

这种新型的TAM-TB实验检测技术是一种不依赖于痰液的血液检测手段,其主要利用免疫学原理来进行检测和判断,当患者处于活性感染期间,在分枝杆菌特定的CD4+ T细胞上表达的标志物CD27往往会缺失,利用标准的细胞内细胞因子染色步骤及多色流式细胞仪检测技术,这种新型检测技术就可以在对血液样本分析24小时后给出可靠的结果。

研究者表示,目前这种新型检测技术可以用于评估坦桑尼亚等肺结核高度流行地区,这种新型检测技术的快速及可靠性使其可以潜在地改善活动性结核儿童患者的诊断结果,为下一步制定这种类型患儿的治疗策略会带来极大的帮助。

后期,研究者们将会对这种检测技术进行优化,研究者希望其也可以应用于HIV感染的儿童身上,从而帮助减少这些患儿的家庭负担;研究者的最终目标是开发一种可靠、快速、非侵入型的诊断技术来对活跃期肺结核患儿进行诊断,这将会对一些肺结核高度流行的国家带来实质性的帮助。

JAMA Pediatr:低血铅也会导致儿童攻击行为等问题

铅对儿童健康的影响已经众所周知,但此前研究主要关注高血铅问题。中美研究人员开展的一项新研究发现,低血铅同样会导致儿童行为问题,例如攻击行为、焦虑和忧郁等。 这项研究发表在新一期《美国医学会杂志·儿科学卷》网络版上。研究负责人、宾夕法尼亚大学副教授刘江红对新华社记者说,他们和上海交大医学院和山东 大学等机构的同事合作,在江苏苏南地区采集了约1600名幼儿园孩子的血液,检测含铅量,并通过向教师和父

Arch Dis Child:利用超声技术可准确诊断儿童手骨骨折

意大利学者报告,超声诊断手骨骨折在儿科患者中的准确率高于90%。超声检查是体格检查以外有效的手骨折诊断方法,该项检查可用于快速评估,超声检查结果为阳性时才需使用X线检查。 超声检查可在避免电离辐射暴露的情况下对骨皮质进行高分辨率的评估,多项研究已指出,接受过充分培训的急诊医师可通过超声快速诊断儿童骨折。 Dr. Rabach及其同事通过一项在204例儿科手创伤患者中进行的横断面研究评估了熟

癌症患儿:妈妈陪你剃光头

据美国《赫芬顿邮报》7月31日报道,美国46名癌症患儿的母亲在波士顿街头齐剃光头,表明与孩子们共同对抗癌症的决心(如图)。 据悉,这项活动已持续了近5年,目的是为癌症研究筹集资金,也给这些不幸的母亲带来安慰。今年这46名母亲为圣博得瑞克基金会筹集了20万美元(1美元约合人民币6元),用于儿科癌症研究。自2010年起,该活动共筹集了近150万美元。癌症患儿安妮卡的母亲今年参与了活动

儿童绘画能力或可预示智力发育水平

新华网伦敦8月19日电英国一项最新研究发现,4岁儿童的绘画能力或能预示他们在10年之后的智力发育水平。不过研究人员同时强调,智力水平由大量因素共同决定,孩子在绘画方面表现不佳并不值得忧虑。英国伦敦大学国王学院研究人员在新一期《心理学》杂志上报告说,他们征集了7752对双胞胎,考察绘画能力、智力发育与遗传因素之间的关系。在受试者4岁时进行的绘画能力测试中,他们需要画出一个小孩,评分标准包括四肢、五官

Lancet:四价登革热疫苗对亚洲儿童具有良好的保护作用

据《柳叶刀》发表的最新研究结果,首次进入三期临床试验的登革热候选疫苗(CYD-TDV)对亚洲儿童展现出稳定的疾病预防作用(56%)和良好的安全性。 登革热属于蚊媒传染病,每年约有3.9亿人口感染,其中9,600百万人会出现感染症状。WHO估计在过去50年中,登革热的全球负担上升了30倍,超过半数的世界人口处于该疾病风险中。 目前并未有任何用于登革热的治疗或预防疫苗获批。由于登革热是由四

儿童参加临床试验知情同意书的设计与操作

新药临床试验主要在成年人中开展,儿童使用的大部分药品并未在儿童中开展过相应的研究,儿童用药较之成人存在更多的安全隐患。而且,越来越多的儿童患上了以前认为只有成年人才会患有的疾病,之前只用于成年人的药物现在也越来越多地用于儿童,如抗糖尿病药、抗高血压药、降脂药、精神类药物等。在儿童患者中进行新药的临床研究的需要变得越来越迫切,因此开展儿童参加的临床试验是促进儿童用药健康发展、保障儿童用药安全的重
