Effects of incentives,age, and behavior on brain activation during inhibitory control: A longitudinal fMRI study

We investigated changes in brain function supporting inhibitory control under age-controlled incentivized conditions, separating age- and performance-related activation in an accelerated longitudinal design including 10- to 22-year-olds. Better inhibitory control correlated with striatal activation during neutral trials, while Age X Behavior interactions in the striatum indicated that in the absence of extrinsic incentives, younger subjects with greater reward circuitry activation successfully engage in greater inhibitory control. Age was negatively correlated with ventral amygdala activation during Loss trials, suggesting that amygdala function more strongly mediates bottom-up processing earlier in development when controlling the negative aspects of incentives to support inhibitory control. Together, these results indicate that with development, reward-modulated cognitive control may be supported by incentive processing transitions in the amygdala, and from facilitative to obstructive striatal function during inhibitory control.     

Confidentiality Discussions and Private Time With a Health-Care Provider for Youth,United States, 2016

Purpose

The objective of the study was to define factors associated with adolescent and young adult (AYA) experiences with private time and having discussed confidentiality and the impact of these experiences on improving delivery of clinical preventive services.

Early onset scoliosis and current treatment methods

ObjectiveProvide an update of the management options for early onset scoliosis patients, including general assessment, conservative and surgical options.MethodsWe included the updated information about the assessment and management options of Early Onset Scoliosis, taking into consideration the non-fusion methods, including the burden on the patient and their family.ResultsWith the heterogeneity of this population, it is difficult to get a consensus about a unified protocol for management. Accordingly, the surgeon dealing with these cases needs to be aware of the broad range of surgical and non-surgical methods when treating these patients.ConclusionThe main aim of early onset scoliosis treatment is to gain a flexible spine associated with normal lung development and thoracic growth. Management needs to be individualized between the surgeon and patient in relation to the etiology and patient conditions.     

农村青少年不同时期家庭逆境与精神病理症状的关联

目的探讨家庭逆境致精神病理症状结局的累积性与关键期效应,为预防与干预逆境伤害提供依据。方法2017年12月,采用方便抽样的方法选取安徽省阜阳地区2所农村学校的710名青少年。采用《童年期不良经历问卷》评估家庭逆境,《MacArthur健康与行为问卷》评价内化症状和外化症状。采用多元线性回归分析家庭逆境发生时间与数量和精神病理症状的关联。结果持续家庭逆境组与内化症状、外化症状增加均有相关性[β值(95%CI)分别为0.35(0.15~0.54),0.16(0.01~0.32)]。家庭逆境数量为2和≥3与内化症状[β值(95%CI)分别为0.20(0.04~0.36),0.42(0.24~0.60)]、外化症状[β值(95%CI)分别为0.14(0.01~0.26),0.23(0.09~0.37)]增加有关。在仅童年期家庭逆境中,家庭逆境数量为2和≥3的内化症状[β值(95%CI)分别为0.23(0.06~0.41),0.34(0.11~0.58)]、外化症状[β值(95%CI)分别为0.17(0.02~0.31),0.21(0.02~0.39)]的风险增高。在持续家庭逆境组中,逆境数量≥3与内化症状、外化症状相关[(β值(95%CI)分别为0.56(0.31~0.82),0.24(0.02~0.45)]。仅青春期家庭逆境与精神病理症状无关。结论家庭逆境的多次发生可增加精神病理症状风险,童年期可能是家庭逆境致精神病理症状的关键期。

目的了解利培酮治疗儿童少年期首发精神分裂症或分裂样精神病的临床疗效、安全性和药物剂量。方法用利培酮对62例年龄<14岁的儿童精神分裂症患者治疗8周,采用简明精神病评定量表(BPRS)评定疗效,副反应量表(TESS)及实验室相应检查评定安全性及副反应。结果总有效率85%。不良反应主要为锥体外系反应及失眠,平均治疗剂量(3.26±0.88)mg/d。结论利培酮对于首发儿童少年期精神分裂症或分裂样精神病的治疗,用药安全、疗效可靠、副反应小、依从性高。     

Les scarifications : le regard de la métamorphose

Scarifications are frequently seen in the passage from adolescence to adulthood. Their nosographic context has expanded to include defensive behavior in reaction to the difficulties of assuming autonomy, or those associated with separation, to an attempt to express acute anxiety in borderline states or in certain cases of psychosis.The transition to adulthood is a particularly exacting period for girls. In a society that places value upon visual appearance, the bodily changes that take place during puberty and the occurrence of the first menstruations are often a traumatic experience, and may temporarily inhibit the acceptance of womanhood. Self-mutilations constitute a corporal limit that may facilitate the adolescent's acceptance of the bodily change towards full femininity.As in the myth of Narcissus, scarifications or superficial cutaneous incisions are a means of providing the possibility of withdrawal into oneself; in an attempt to control underlying tension and anxiety the adolescent voluntarily causes blood to appear and disappear through self-mutilation, so that it is no longer perceived as a menace. Scarifications therefore allow girls an appropriation of the female body, and thus may be a means of their coming to terms with the metamorphosis that is taking place. This hypothesis has been illustrated through a specific case history.     

神经纤维瘤蛋白在先天性脊柱侧凸患者成骨细胞和软骨细胞中的表达

目的：检测神经纤维瘤蛋白在先天性脊柱侧凸患者成骨细胞和软骨细胞中的表达。方法：6例先天性脊柱侧凸患者，在后路手术时取髂骨及髂骨生长板，分离、培养成骨细胞和软骨细胞，分别行碱性磷酸酶染色和甲苯胺蓝染色。逆转录-多聚酶链反应（RT—PCR）检测神经纤维瘤蛋白mRNA．间接免疫荧光和Westemblot检测神经纤维瘤蛋白在成骨细胞和软骨细胞中的表达。结果：先天性脊柱侧凸患者成骨细胞和软骨细胞中存在Ⅱ型神经纤维瘤蛋白表达，该蛋白主要分布在细胞浆，所表达蛋白为三磷酸鸟苷酶活化蛋白（GAP）活性较弱的Ⅱ型异构体。结论：先天性脊柱侧凸患者成骨细胞和软骨细胞中存在神经纤维瘤蛋白表达，但该蛋白是否通过对成骨细胞和软骨细胞的影响导致骨骼系统异常还有待于进一步研究。     

Caring for the Involuntarily Hospitalized Adolescent: The Issue of Power in the Nurse-Patient Relationship

TOPIC: The power relations between involuntarily hospitalized adolescents and their caregivers from the viewpoint of theory development in nursing and the concept of medicalization. PURPOSE: To contribute to the development of nursing theories that can guide nursing care of involuntarily hospitalized adolescents by examining the power relations between the adolescents and their caregivers. SOURCES: Published literature in medical sociology, and nursing and psychiatric ethics. Nursing and psychiatric literature, in which Michel Foucault's theories are used to explicate the disciplinary power of psychiatry. CONCLUSIONS: To empower involuntarily hospitalized adolescents nurses must both recognize the inevitable power imbalance and seek guidance from the egalitarian ideals of nursing. Nurses can draw from postmodern thinkers who dismiss the idea that one theory can explain human relationships.
