Status of Women and Infants in Complex Humanitarian Emergencies

Women and children bear the greatest burden in the midst of war and long‐term disasters. Complex humanitarian emergencies are characterized by social disruption, armed conflict, population displacement, collapse of public health infrastructure, and food shortages. Humanitarian assistance for refugees and internally displaced populations requires particular attention to the common issues affecting morbidity and mortality in women and infants. Gender‐based violence and reproductive health concerns are discussed within the context of populations affected by conflict and forced migration. Recommendations for midwives and women's health care providers engaging in care for women and children in complex humanitarian emergencies are discussed.     

Short term correlates of the Neuro Emotional Technique for cancer-related traumatic stress symptoms: A pilot case series

Introduction As many as one quarter of all cancer survivors report traumatic stress symptoms from cancer-related experiences. While the majority of these patients do not meet the criteria for posttraumatic stress disorder (PTSD), there is growing evidence that subsyndromal symptoms can significantly contribute to functional impairment and negative health outcomes. Treatment options for the hallmark symptoms of traumatic stress—unpleasant, intrusive thoughts and avoidant behaviors—have not been well investigated for the cancer survivorship population. Materials and methods Seven female cancer survivors with traumatic stress symptoms from cancer-related experiences and no other major psychopathology, were enrolled to receive three sessions of Neuro-Emotional Technique (NET), a brief, targeted treatment that combines traditional desensitization principles with complementary modalities. Results Psychological outcome measures (Impact of Event Scale (IES) and Subjective Units of Distress (SUD) and physiological measures (Heart Rate (HR) and Skin Conductance Level (SCL) demonstrated the following changes: 71% on IES, 88% SUD, 74% on HR, and 65% on SCL following the intervention. Statistically significant changes were observed for all four parameters, and effect size g for proportion improved were 0.50 each for IES, SUD, and HR, and 0.20 for SCL. Conclusions These cases suggest feasibility of the NET intervention for cancer-related traumatic stress and the potential for change in symptoms and physiological reactivity. Further investigation is needed to determine the specific and long-term effects of such an approach. Implications for cancer survivors Traumatic stress from cancer-related experiences might represent a constellation of symptoms that are amenable to brief, targeted interventions.

停止尿床年龄与青少年自杀行为的关系

目的探讨停止尿床年龄与青少年自杀行为的关系。方法对1920名11岁～16岁的青少年进行调查,由父母完成包括青少年生长发育史、自杀行为、抑郁症状、攻击行为及家庭环境等定式问卷。结果在控制一系列儿童及家庭情况变量后,多变量Logistic回归模型显示3岁后停止尿床与青少年自杀行为的危险性增加显著相关,停止尿床年龄与青少年自杀行为之间存在量效关系（3岁～4岁停止尿床OR值为2.1,5岁及以上停止尿床OR值为3.6）。中介变量分析显示,停止尿床时间晚对自杀行为的效应,至少部分通过抑郁及攻击行为中介。结论停止尿床时间晚可能是青少年自杀行为的早期神经发育预测因素,应进一步探讨青少年自杀行为的早期神经发育危险因素及潜在机制。     

智力残疾的适应性行为评估

适应性行为评估是智力残疾诊断与干预的必要依据。适应性行为的概念至今仍未有统一的观点，AAMR（2002）认为，适应性行为指的是概念、社会和应用3方面的技能，它的限制会影响个体的日常生活运作，进而影响其生活适应。对适应性行为进行评估的方法主要有测验法、行为观察法、功能性评估、生活质量评估和社会技能测量。无论使用什么方法进行评估，都应当以改善智力残疾个体现有状况为目的，考虑到各种评估方法的局限性，对智力残疾个体宜进行全面评估。     

黔东少数民族儿童行为问题与父母教养方式研究

目的探讨西部少数民族儿童行为问题及其与父母养育方式的关系,为少数民族地区开展心理健康教育提供理论依据。方法采用Achenbach儿童行为量表(CBCL)和儿童抚养行为问卷(CRPR)对415名苗族、土家族和侗族儿童进行调查。结果行为问题检出率为29.63%,其中男童为29.94%,女童为29.25%。男童检出率较高的因子为强迫、抑郁、交往不良、分裂样,女童检出率较高的因子为抑郁、分裂样强迫、多动。男童行为问题的绝大多数因子与父母的拒绝、惩罚定向呈显著的正相关,女童行为问题的多数因子与父母的拒绝呈显著正相关。结论黔东地区少数民族儿童行为问题显著高于全国水平,父母教养方式影响儿童的行为问题。     

伴ADHD的对立违抗性障碍儿童行为特征分析

目的：了解伴注意缺陷／多动障碍(ADHD)的对立违抗性障碍(0DD)患儿的行为特征。方法：以ICD-10作为诊断标准对门诊就诊儿童进行诊断，得到ODD伴ADHD者40例(64.52％)．ODD不伴ADHD者22例(35．48％)。自编家庭情况调查表调查患儿的基本情况。用家长填Achenbach儿章行为量表评定儿童行为。结果：与ODD组相比。合并ADHD组的家长更多对患儿经常打骂和严厉管教：对儿童的不良行为更多地采取打骂的方式。合并组父亲急燥易怒者比ODD组多；合并组起病年龄及就诊年龄比ODD组早：合并组在CBCI。思维、注意问题，违纪、攻击行为，外化性问题，行为总分均高于ODD组。结论：ODD合并ADHD的患儿在思维、注意问题，违纪、攻击行为，外化性问题方面表现更突出，家长对儿童管教方式及不良行为处理方式影响ODD的发生。提示要注重ODD、ADHD的早期干预。     

Impairment of schedule-controlled behavior by pre- and postnatal exposure to hexachlorobenzene in rats

 Hexachlorobenzene (HCB) is still frequently found at elevated levels in human adipose tissue and breast milk. As intoxication with HCB causes neurological disturbance in human beings, the purpose of the present study was to examine neurobehavioral functions in rats after pre- and postnatal exposure. Female rats were fed diets with 0, 4, 8, or 16 mg HCB/kg diet. Exposure started 90 days prior to mating and was continued throughout mating, gestation, and lactation. Thereafter, the offspring were given the same diets as their respective mothers. HCB levels were determined in the brain, the liver, and in the adipose tissue from virgin rats, dams, and the offspring. Concentrations on a lipid basis were found to decline in the order adipose>liver>brain. The exposure levels chosen did not cause gross toxic effects in dams or offspring. There were dose-related increases in liver-to-body-weight ratios in exposed dams, but not in unmated females treated alike. Behavioral testing was conducted in the offspring. Examination of open-field activity on PND 21, and of active avoidance learning on PND 90 failed to reveal significant differences between groups. Training of operant behavior started at the age of 150 days in the offspring from the control, the 8-mg group, and the 16-mg group. Animals were trained on a fixed interval schedule of 1 min (FI-1). On this schedule, responses were reinforced by a food pellet every time 1 min had elapsed after the preceding reinforcement. There were dose-dependent reductions in the post-reinforcement pause, e.g. the time between each reinforcement and the first reaction emitted after it. In addition, the index of curvature, which describes the efficiency of performance on the FI-1 schedule, was decreased in a dose-dependent fashion.

Pharmacological interactions between serotonin and dopamine on behavior in the squirrel monkey

 The behavioral effects of GBR 12909, a selective dopamine uptake inhibitor, were determined in squirrel monkeys trained to respond under a fixed-interval (FI) schedule of stimulus termination and a second-order schedule of IV drug self-administration. Intermediate doses of GBR 12909 increased FI response rate markedly, and the highest dose decreased response rate below control values. The 5HT uptake inhibitors, alaproclate and fluoxetine, and the 5HT agonist, quipazine, attenuated the behavioral-stimulant effects of GBR 12909, whereas the 5HT_2A/2C antagonist, ritanserin, enhanced the behavioral-stimulant effects of the lowest dose. GBR 12909 reliably maintained self-administration, and ritanserin increased response rate maintained by the highest dose. The dopamine agonist, quinpirole, increased FI response rate in only one of three subjects, and ritanserin enhanced the behavioral-stimulant effects of quinpirole in that subject. The dopamine agonist, apomorphine, only decreased FI response rate, and ritanserin did not alter its behavioral effects. The pharmacological profile of GBR 12909 administered alone and in combination with selective 5HT drugs in the present study was similar to that obtained previously with cocaine, further demonstrating that 5HT can reliably modulate the behavioral effects of psychomotor stimulants with prominent dopaminergic actions.
