儿童室管膜瘤的临床研究进展

室管膜瘤是一种原发于神经上皮的中枢神经系统肿瘤，病变累及脑和脊髓，多发于儿童。基因分型的新分类方法，为室管膜瘤的治疗和预后评估提供了更为可靠的依据。室管膜瘤对辅助治疗的敏感性低是造成患儿预后较差的重要原因之一。该文对近年来儿童室管膜瘤的分型、诊断、治疗策略等进行综述。     

Barriers to vaccination service delivery within general practice: opportunity to make a sustainable difference in Aboriginal child health?

Objective: To identify behavioural barriers of service provision within general practice that may be impacting the vaccination coverage rates of Aboriginal children in Perth, Western Australia (WA). Methods: A purposive developed survey was distributed to 316 general practices across Perth and three key informant interviews were conducted using a mixed‐methods approach. Results: Of the surveyed participants (n=101), 67.4% were unaware of the low vaccination coverage in Aboriginal children; 64.8% had not received cultural sensitivity training in their workplace and 46.8% reported having inadequate time to follow up overdue child vaccinations. Opportunistic vaccination was not routinely performed by 30.8% of participants. Key themes identified in the interviews were awareness, inclusion and cultural safety. Conclusion: Inadequate awareness of the current rates, in association with a lack of cultural safety training, follow‐up and opportunistic practice, may be preventing greater vaccination uptake in Aboriginal children in Perth. Cultural safety is a critical component of the acceptability and accessibility of services; lack of awareness may restrict the development of strategies designed to equitably address low coverage. Implications: The findings of this study provide an opportunity to raise awareness among clinicians in general practice and inform future strategies to equitably deliver targeted vaccination services to Aboriginal children.     

Fathers of children with autism spectrum disorder: Their perceptions of paternal role a predictor of caregiving satisfaction,self-efficacy and burden

BackgroundThe positive effect of a father’s involvement in children’s upbringing is now recognised. However, research on fathers raising children with autism spectrum disorder (ASD) are still few. This study examines the relationship between the perception, fathers of children with ASD have of the importance of their role in the development of their children and the feelings (self-efficacy, caregiving burden, satisfaction) they express about their parenting experience.MethodSixty-three Swiss Italian fathers of children with ASD completed The Role of the Father Questionnaire (ROFQ), three sub-scales of the Caregiver Survey, a subtest of the Child Adjustment and Parent Efficacy Scale and a home-made questionnaire measuring Perceived Social Support.ResultsThe results from hierarchical multiple regression analyses show that the importance that fathers attach to the paternal role predicts positively their caregiving satisfaction and their feeling of self-efficacy. The children’s challenging behaviours predict positively the caregiving burden whereas the assessment of social support predicts it negatively.ConclusionsThe perception of the importance of the paternal role needs to be considered in the support offered to families with a child with ASD. A better understanding of the fathers’ feelings could be of value for the programmes.

The feasibility of the draw-and-write technique in exploring the resilience of children orphaned by AIDS

Worldwide, researchers routinely study children indirectly through adults who act as proxies for such children. The call for researchers to rather study children directly and adopt less intrusive child-friendly methodologies has become louder. The draw-and-write technique is regarded as a less intrusive child-friendly method of collecting data that can be used for this purpose. This paper reports the findings of a qualitative study that sought to establish the feasibility of the draw-and-write technique in exploring the resilience of children orphaned by AIDS. This study involved a convenience sample of 23 IsiXhosa-speaking orphaned children aged from 13 to 17. The participants were in grades 6 to 10 and they resided in two child and youth care centres in the Eastern Cape province of South Africa. As part of the draw-and-write technique the participants were asked to make drawings of what enabled them to cope with their lives and to write short narratives in which they explained their drawings. Inductive content analysis was used to analyse the data and this process yielded two main themes, namely: personal protective resources and socio-ecological protective resources. The findings show that complex combinations of personal and socio-ecological resilience resources enabled the resilience of the orphaned children. The findings challenge researchers not to be oblivious to alternative child-friendly methods of research such as the draw-and-write technique when young people are the unit of analysis. The findings of this study have implications for research as well as practice in the field of education and psychology.     

幼儿不同跑步着地方式的生物力学特征

文题释义：跑：跑是双脚交替接触地面的周期性运动，但跑有一个双脚都离开地面的腾空期。幼儿在 1 岁多开始学习跑步，最初是走跑结合的移动方式，由于身体发育不完善，下肢力量弱，平衡能力差，容易摔倒；到 2.5岁，幼儿跑步的腾空阶段明显；到 6岁，早期跑步的特点基本消失。 着地方式：指的是人体在跑步着地阶段足部接触地面的方式，一般分为3种方式：分别为足跟着地(fore foot strike)，跟骨先接触地面；全足着地(mid foot strike)，全脚掌着地，即足跟与前足同时接触地面；前足着地(rear foot strike)：前足部首先接触地面。 背景：成年人跑步着地方式一直是国内外学者研究的重点，而幼儿跑步的着地方式也是不容忽视的内容。 目的：运用生物力学方法探究幼儿在跑步过程中，不同着地方式下的运动学和动力学指标的差异，为幼儿正确的跑步着地方式提供科学依据。 方法：在北京市海淀区某公立幼儿园中随机抽取幼儿74名，按年龄分为3岁组、4岁组、5岁组，采用BTS红外动作捕捉系统、Kistler三维测力台和VIXTA录像解析系统同步采集幼儿跑步过程中不同着地方式下的运动学、动力学数据；运用Anybody 5.2仿真建模软件计算下肢肌肉力量指标。试验前向受试者父母详细解释并签署知情同意书，试验方案符合北京师范大学的相关伦理要求。 结果与结论：①3岁组全足着地的比例最高，足跟着地的比例最低，5岁组全足着地的比例最低，足跟着地的比例最高；前足着地者的蹬伸时间大于足跟着地(P < 0.01)和全足着地(P < 0.05)；②着地时刻，踝屈曲角度足跟着地者大于前足着地(P < 0.01)和全足着地者(P < 0.05)，全足着地者大于前足着地(P < 0.05)；前足着地者髋内收-外展角度、最大髋内收-外展角、髋内-收外展的关节变化量及最大膝内收-外展角速度大于足跟着地(P < 0.01)和全足着地者(P < 0.05)；前足着地者的踝屈伸最小值大于足跟着地者(P < 0.05)，而最大髋内收-外展角速度小于足跟着地者(P < 0.05)；③足跟着地和全足着地者的腓骨短肌、腓骨长肌、第三腓骨肌的肌力大于前足着地者(P < 0.05)，前足着地者的股中间肌、股外侧肌下束、股外侧肌上束、股内侧肌下束、股内侧肌上束、股内侧肌中束肌力均大于足跟着地(P < 0.01)和全足着地者(P < 0.05)；④结果提示：在3-6岁阶段，幼儿多采用足跟或全足着地模式进行奔跑，以满足自己在跑步过程的稳定性，随着年龄的增长，逐渐出现前足着地方式的跑步模式；前足着地能够动用更多髋关节和膝关节额状面的运动来维持人体运动中的稳定，足跟着地和全足着地能够动用更多的小腿前侧和后侧的肌力，而前足着地动用更多的大腿前侧肌力。 ORCID: 0000-0002-8337-3931(赵盼超) 中国组织工程研究杂志出版内容重点：组织构建；骨细胞；软骨细胞；细胞培养；成纤维细胞；血管内皮细胞；骨质疏松；组织工程
