儿童结核病的合理用药

结核病是严重危害儿童健康的重要传染性疾病，儿童结核病的发病率影响未来成人结核患者的数量，重视儿童结核病对疾病控制具有重要意义，要控制和消灭结核病，必须十分重视儿童结核病的防治，然而不规范的治疗将直接影响治疗效果，该文就儿童结核病的合理用药进行阐述。     

儿童高胆红素血症

儿童高胆红素血症常表现为黄疸，是儿童特别是婴幼儿普遍存在的一种症状，各种病理生理学、解剖学、感染性、自身免疫性疾病及遗传代谢性因素及疾病均可引起黄疸。不同的原因导致的黄疸其严重程度及预后不同，并且有不同的时间敏感性和不同的治疗计划。早期诊断和评估、并给予个性化的优化治疗至关重要。随着分子检测技术的发展，二代测序技术使临床医生能够快速有效的对临床实践中无法通过常规血液检查直接诊断的疾病进行分子学诊断，进而精准治疗。文章主要介绍儿童高胆红素血症常见病因及其诊治策略。     

川崎病静脉注射丙种球蛋白无反应预测模型研究现状

川崎病(Kawasaki disease，KD)是一种急性自身免疫性系统性血管炎，是发达国家儿童获得性心脏病的主要病因。KD最严重的后果是冠状动脉病变(coronary artery lesions，CALs)，与KD的预后相关。临床研究证实静脉注射丙种球蛋白(IVIG)耐药是CALs的独立危险因素。近年来，一系列的预测模型已被开发来评估IVIG耐药的风险。然而，目前基于KD儿童人口学特征、临床表现、实验室检查及遗传特性的IVIG耐药性预测评分系统在不同民族和同一民族不同地区的人群中存在显著差异，尚未建立适用普遍人群的预测模型。     

Overview of Recognition and Prevention of Child Sex Trafficking in the Primary Care Setting: A Primer for Nurse Practitioners

Child sex trafficking (CST) has become a global public health crisis and is a $150 billion criminal enterprise. Nurse practitioners are key in the recognition and prevention of CST in health care settings. Evidence demonstrates that up to 80% of CST victims have had a recent health care encounter. It is the role of the NP in practice to understand risk factors, screen for CST, and educate parents and caregivers on signs of victimization and prevention.     

A commitment to marginalized children in the European Union: The hope and challenges of the EU Child Guarantee

While children in general are usually seen as a societal priority, many children are disadvantaged by marginalization, with adverse effects on health and development. Following feasibility studies, the European Commission has now adopted a formal Child Guarantee of service access. This paper links the Feasibility Studies to other reports on the need to address marginalized and institutionalized children. The problems in identifying and quantifying such children are outlined, as are the challenges of planning for these groups of children and the difficulty of finding universal definitions and data. This European Union initiative is timely, given that around a quarter of European children are marginalized, while the effects of Covid-19 will add to this marginalization.     

Estimated Reductions in Added Sugar Intake among US Children and Youth in Response to Sugar Reduction Targets

BackgroundIn 2021, the National Salt and Sugar Reduction Initiative (NSSRI) released voluntary sugar reduction targets for packaged foods and drinks in the United States.ObjectiveThe objectives of this study were to describe trends in added sugar intake from NSSRI foods and beverages among children and youth and estimate possible reductions if industry were to meet the targets.DesignThis study consisted of cross-sectional and trend analyses of demographic and 24-hour dietary recall data from eight survey cycles (2003-2004 to 2017-2018) of the National Health and Nutrition Examination Survey.Participants/settingThe study sample included 23,248 children and youth (aged 2 to 19 years).Main outcome measuresThe main outcome measure was the percent of daily calories from added sugar for foods and beverages in NSSRI categories.Statistical analyses performedFoods and beverages reported by participants were mapped to one of the NSSRI’s categories or coded as a non-NSSRI item. Trends over time in added sugar intake were assessed using regression models. To assess possible reductions in added sugar intake if industry were to meet the targets, sales-weighted mean percent reductions for 2023 and 2026 targets were applied to NSSRI items in the 2017-2018 National Health and Nutrition Examination Suvey data. Results were examined overall and by demographic characteristics.ResultsFrom 2003-2004 to 2017-2018, added sugar intake from NSSRI foods and beverages declined, but consumption remained high. During 2017-2018, NSSRI categories accounted for 70% of US child and youth added sugar intake. If industry met the NSSRI targets, US children and youth would consume 7% (2023 targets) to 21% (2026 targets) less added sugar.ConclusionsAlthough added sugar intake from NSSRI foods and drinks has declined over the past decade, added sugar intake from all sources remains high and consumption of added sugar from certain NSSRI categories has remained steady over time. If met, the NSSRI targets are expected to result in meaningful reductions in added sugar intake for US children and youth.     

儿童1型糖尿病骨密度变化及影响因素分析

目的 测定儿童1型糖尿病(T1DM)患者骨密度(BMD),分析探讨骨密度变化的影响因素。方法 选取于2018年1月—2021年6月于我院收治的儿童1型糖尿病患者76例,收集性别、年龄、发病年龄、身高、体重、BMI、病程等基本资料,检测空腹血糖、空腹C肽、糖化血红蛋白(HbA1c)、血碳酸氢根(HCO3-)、血清碱性磷酸酶(ALP),应用双能X线吸收测定法测定骨密度,获取Z值。结果 76例儿童1型糖尿病患者骨密度Z值为-0.93±2.14。HbA1c、病程与骨密度Z值呈负相关,差异具有统计学意义(分别B=-0.334,P<0.001;B=-0.191,P=0.017)。结论 儿童1型糖尿病患者骨密度低于健康儿童,血糖控制不良、病程长是1型糖尿病儿童骨密度减低的危险因素。     

HPRT1基因变异致Lesch-Nyhan综合征1例报告

Lesch-Nyhan综合征是一种罕见的X连锁隐性遗传病，在自伤行为出现前，易被误诊为脑瘫，延误诊治。先证者，男，8岁7个月，因发育落后8年余，肌张力异常就诊。多次血生化均提示尿酸增高，遗传学分析结果证实患儿为HPRT1基因c.200＿201delTG变异，经ACMG评级为疑似致病性变异，Sanger测序验证发现该变异遗传自患儿母亲，为未报道的新变异，从而确诊为HPRT1基因相关Lesch-Nyhan综合征，口服别嘌醇片、碳酸氢钠片6月后尿酸水平较前明显下降，仍无自伤行为。临床上遇到不明原因脑瘫表现者，应及早行遗传学检查，以帮助早期诊断和遗传咨询。
