“Driven and Tense,Stressed Out and Anxious”: Clinicians’ Perceptions of Post-Traumatic Stress Disorder Symptom Expressions in Adults with Autism and Intellectual Disability

ABSTRACT

Introduction

Individuals with autism spectrum disorder (ASD) and intellectual disability (ID) seem to be at increased risk for post-traumatic stress disorder (PTSD), but knowledge is sparse regarding its identification in this population. Previous research indicates that certain symptoms of PTSD may be more easily recognized, and that identifying reexperiencing and avoidance is particularly challenging.     

Innovative Thinking on Endpoint Selection in Clinical Trials

ABSTRACT

In clinical trials, selection of appropriate study endpoints is critical for an accurate and reliable evaluation of safety and effectiveness of a test treatment under investigation. In practice, however, there are usually multiple endpoints available for measurement of disease status and/or therapeutic effect of the test treatment under study. For example, in cancer clinical trials, overall survival, response rate, and/or time to disease progression are usually considered as primary clinical endpoints for evaluation of safety and effectiveness of the test treatment under investigation. Once the study endpoints have been selected, sample size required for achieving a desired power is then determined. It, however, should be noted that different study endpoints may result in different sample sizes. In practice, it is usually not clear which study endpoint can best inform the disease status and measure the treatment effect. Moreover, different study endpoints may not translate one another although they may be highly correlated one another. In this article, we intend to develop an innovative endpoint namely therapeutic index based on a utility function to combine and utilize information collected from all study endpoints. Statistical properties and performances of the proposed therapeutic index are evaluated theoretically. A numerical example concerning a cancer clinical trial is given to illustrate the use of the proposed therapeutic index.     

维生素D在孤独症谱系障碍中作用的研究进展

孤独症谱系障碍(ASD)是影响儿童健康的严重公共问题之一,以社交沟通障碍、兴趣或活动范围狭窄以及重复刻板行为为特征。近年来越来越多的研究显示,ASD患儿维生素D(VitD)水平明显低于同龄健康儿童,VitD缺乏可能与ASD的发病机制相关。本文就VitD与ASD的相关研究进行综述。     

Pyramidal and posterior osseous release for maxillary superior/posterior mobilization using an ultrasonic bone-cutting device after Le Fort I osteotomy

AimThe purpose of this study was to evaluate the efficiency of pyramidal and posterior osseous release (PPOR) for maxillary impaction using an ultrasonic bone-cutting device after Le Fort I (LFI) osteotomy.Materials and methodsIn total, 31 Japanese adults with jaw deformities, diagnosed as having maxillary excess with mandibular prognathism or deficiency, underwent LFI osteotomy and bilateral sagittal split osteotomy. The patients were divided into two groups: a trimming group (15 patients, four men and 11 women; mean age 24.8 years) and a PPOR group (16 patients, seven men and nine women; mean age 22.8 years). In the trimming group, osseous interference around the descending palatine artery (DPA) was removed using forceps, rounding bur, and reciprocating rasp. The PPOR technique was used to remove osseous fragments created by V-shaped osteotomy around the DPA following vertical osteotomy behind the DPA using an ultrasonic bone-cutting device (Variosurg 3; NSK, Tochigi, Japan). The operative times for maxillary osteotomy, total operative times (including bilateral sagittal split osteotomy), and total blood loss were assessed.ResultsThe mean planned amounts of maxillary impaction were 4.37 ± 1.27 mm in the trimming group and 4.38 ± 1.36 mm in the PPOR group (p = 0.98). The mean maxillary operative time for the PPOR group was significantly shorter, by 25.5% (p < 0.001). Total operative time for the PPOR group was also significantly shorter, by 24.3% (p < 0.001). Mean blood loss was significantly lower in the PPOR group than in the trimming group (p = 0.003).ConclusionThe PPOR technique for maxillary impaction after LFI osteotomy shortened the operative time and enabled secure reduction of the maxilla in patients who required the treatment of maxillary impaction with preservation of the DPA bundle.     

《艾滋病诊疗指南第三版(2015版)》更新解读

2015年中华医学会感染病学分会艾滋病学组发布了第三版《艾滋病诊疗指南》。新版指南强调抗病毒治疗时点前移:一旦成人确诊感染人类免疫缺陷病毒(HIV), 若无禁忌宜尽早启动抗HIV治疗。对于合并机会性感染的HIV感染者, 在感染控制、病情稳定后也应及早开始抗病毒治疗。尤其强调HIV合并结核患者在CD4阳性淋巴细胞数少于200/μL的情况下, 建议抗结核两周内即开始抗病毒治疗。在抗HIV治疗用药中, 淘汰了一些毒副作用大、依从性较差的药物, 如司他夫定、去羟肌苷、茚地那韦等, 优选抗病毒效力强、服药方便的组合, 如拉米夫定、替诺福韦、依非韦伦组合。对于HIV感染的婴幼儿, 亦主张及早抗HIV治疗。对于五岁以内的幼儿, 主张确诊后即启动抗病毒治疗。对于HIV感染的孕产妇, 建议尽快予以全程、联合抗HIV治疗, 寓防于治。     

Commentary: Broadening the research remit of participatory methods in autism science – a commentary on Happé and Frith (2020)

Autism science has transformed beyond recognition in the last two decades. International investment has grown extensively and the number of papers published on autism has increased 10-fold (Pellicano et al., 2014), far surpassing publications on related topics. The sheer amount of scientific research on autism has no doubt been instrumental in many of the discoveries and insights so eloquently described by Happé and Frith (2020). But, as autistic scientist Michelle Dawson reminds us, quality matters too and, for that reason, it is a delight to recognise the contribution that both Happé and Frith have made, dramatically changing our understanding of autism in a host of ways.     

腹腔镜与开腹手术治疗老年胆囊炎患者的分析

目的观察在治疗老年急性胆囊炎患者采取开腹手术与腹腔镜手术的治疗效果并分析。方法将2017年1月—2018年9月期间医院收治的74例急性胆囊炎患者采用随机数字表法分为观察组和对照组,对照组37例采取开腹手术治疗,观察组37例采取腹腔镜治疗,对比两组治疗效果。结果观察组并发症发生率5.4%、治疗总有效率97.3%优于对照组的24.3%、78.4%,P<0.05。观察组术中出血量(15.7±3.4)mL、手术时间(40.7±4.4)min、住院时间(7.1±1.8)d、术后肠道恢复时间(3.3±1.2)d均低于对照组的(46.4±3.5)mL、(68.6±14.7)min、(12.6±2.3)d、(6.1±1.5)d,P<0.05。观察组躯体疼痛(87.3±0.5)分、总体健康(85.2±1.2)分、精神状况(86.4±1.3)分、社会活动评分(90.2±1.3)分均高于于对照组(78.3±1.2)分、(70.3±10.8)分、(71.3±0.5)分、(75.5±2.1)分,对比有统计学意义(P<0.05)。结论腹腔镜手术治疗老年急性胆囊炎患者效果良好,可有效减少患者病程,促进康复和提高生活质量,值得推广。
