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.

福建省原发性肝癌遗传因素分析

为了探讨遗传因素与福建省原发性肝癌的关系,应用多种对照配对的病例对照研究方法,对100个原发性肝癌和200个对照家系进行了遗传流行病学分析。结果显示,原发性肝癌先证者一、二级亲属患病率明显高于对照组患病率,分离比为0.04146～0.08654,遗传度加权均值为63.52±4.22％。提示原发性肝癌系多基因遗传病,遗传易感性是原发性肝癌的危险因素之一,原发性肝癌的发生是遗传和环境多种因素共同作用的结果。     

Identifying patients at risk for,and treatment of major psychiatric complications of cancer

A critically important aspect of supportive care in cancer is the prompt recognition and effective treatment of psychiatric complications. Psychiatric disorders such as depression, anxiety and delirium occur in a signifcant percentage of cancer patients, particularly as disease advances and as cancer treatments become more aggressive. This paper reviews factors that can be utilized to identify patients who are at increased risk for developing psychiatric complications, such as those with advanced disease, certain cancer treatments, uncontrolled physical symptoms, functional limitations, lack of social support, and past history of psychiatric disorder. Methods of diagnostic assessment and strategies for managing depression, anxiety, delirium and suicidal ideation are also reviewed.Presented as an invited lecture at the 6th International Symposium: Supportive Care in Cancer, New Orleans, La., USA, 2–5 March 1994

A daily process design study of attentional pain control strategies in the self-management of cancer pain.

This study investigated the use of attentional control strategies in the self-management of pain using daily process design methodology. Twenty six cancer patients with pain completed diaries 3 times daily for 10 days. Diaries incorporated measures of pain intensity, affect, coping, coping efficacy, and the novelty and predictability of pain, and participants completed a cross-sectional measure of catastrophizing. At the across-person level, focusing on pain was associated with increased negative affect, and the use of pain focusing strategies was positively correlated with experiencing pain that was novel in its location or quality. Distractions that were interesting, important and pleasant were positively correlated with positive affect, perceptions of control over pain and ability to decrease pain. Over-prediction of pain was positively correlated with catastrophizing, and negatively correlated with perceptions of control over and ability to decrease pain. The within-person analysis (ARIMA modelling) showed that catastrophizing moderated the effects of pain focusing strategies, novel pain and over-predictions of pain. Meta-analysis of the ARIMA models revealed that the within-person effects of using attentional strategies did not generalize across the sample. These findings indicated that the effects of distraction strategies are influenced by their motivational-affective significance rather than the frequency with which they are used, and provided further evidence that the threat value of pain influences the way in which people cope with their pain. Theoretical and clinical implications are discussed.

DNA双链断裂残留损伤与癌细胞辐射敏感性研究

目的 了解不同组织来源癌细胞株和人体肿瘤组织原代细胞的DNA双链断裂损伤修复的个体差异性,探寻预测癌细胞辐射敏感性的生物指标。方法 ⁶⁰Co γ射线照射诱发DNA损伤,脉冲电场凝胶电泳检测DNA双链断裂损伤修复,细胞克隆形成能力法检测细胞辐射敏感性。结果 8个不同组织来源癌细胞株的辐射敏感性有较大的差异(D₀为0.65~2.15 Gy),不同细胞株20 Gy γ射线照射诱发产生的DNA双链断裂原初损伤有一定的差别,但与细胞辐射抗性无相关性。辐射敏感细胞SX-10的DNA双链断裂修复缺陷发生在早期快速修复相,而A2780细胞的修复缺陷是发生在晚期慢速修复相。20 Gy照射修复2 h后DNA双链断裂残留量与细胞辐射敏感性指标D₀或SF₂值有显著的相关性。不同个体患者脑肿瘤组织原代细胞之间,辐射诱发DNA双链断裂的修复反应存在明显差异,修复2 h后残留损伤的个体差异性分布类似于癌细胞株。结论 DNA双链断裂残留损伤与癌细胞辐射抗性有显著相关性,可作生物指标预测肿瘤组织细胞对放射治疗的反应性。     

RGD-based strategies for selective delivery of therapeutics and imaging agents to the tumour vasculature

During the past decade, RGD-peptides have become a popular tool for the targeting of drugs and imaging agents to alphavbeta3-integrin expressing tumour vasculature. RGD-peptides have been introduced by recombinant means into therapeutic proteins and viruses. Chemical means have been applied to couple RGD-peptides and RGD-mimetics to liposomes, polymers, peptides, small molecule drugs and radiotracers. Some of these products show impressive results in preclinical animal models and a RGD targeted radiotracer has already successfully been tested in humans for the visualization of alphavbeta3-integrin, which demonstrates the feasibility of this approach. This review will summarize the structural requirements for RGD-peptides and RGD-mimetics as ligands for alphavbeta3. We will show how they have been introduced in the various types of constructs by chemical and recombinant techniques. The importance of multivalent RGD-constructs for high affinity binding and internalization will be highlighted. Furthermore the in vitro and in vivo efficacy of RGD-targeted therapeutics and diagnostics reported in recent years will be reviewed.     

Laryngeal Transplantation in 2005: A Review

There is no good surgical, medical or prosthetic solution to the problems faced by those with a larynx whose function is irreversibly damaged by tumor or trauma. Over the past 10 years, the pace of research designed to establish laryngeal transplantation as a therapeutic option for these persons has increased steadily. The biggest milestone in this field was the world's first true laryngeal transplant performed in Cleveland, Ohio in 1998. The recipient's graft continues to function well, in many respects, even after 7 years. However, it has also highlighted the remaining barriers to full-scale clinical trials. Stimulated by these observations, several groups have accumulated data which point to answers to some of the outstanding questions surrounding functional reinnervation and immunomodulation. This review seeks to outline the progress achieved in this field by 2005 and to point the way forward for laryngeal transplantation research in the 21st century.
