Cancer support groups – are they effective?

Cancer causes significatlt emotional distress to a considerable majority of patients. Many of these patients typically receive little formal psychological intervention. Support groups, however, have provided one forum from which patients can attempt to gain help and can use to overcome some psychological trauma that accompanies the cancer hagnosis, subsequent treatment and relapse. This article reviews past studies of professionally run cancer support groups as opposed to psychological intervention groups. These studies are considered in light of the proposed benefits and the methodological limitations frequently inherent in such studies.     

大蒜素对脑局灶缺血大鼠血小板活化功能及其结构的影响

目的：观察大蒜素对脑局灶缺血大鼠血小板活化功能或轻药物诱导的血小板活化功能及其结构的影响。方法：（1）将SD大鼠随机分为（空白组、大蒜素大剂量组和小剂量组）3组，于末次给予试药1．5h后颈总动脉插管取血，加入诱导剂二磷酸腺苷（ADP）或胶原，测定血小板最大聚集率；（2）采用化学刺激（FeCl3)诱导血栓闭塞法制备大鼠急性大脑中动脉血栓模型，随机分为（假手术组、模型组、大蒜素大剂量组和小剂量组）4组，给药方法同实验（1），颈总动脉插管取血后分离血浆，测定血浆血栓烷B2（TXB2）、6－酮－前列腺素F1α(6-keto-PGF1α）含量；（3）加入ADP孵育激活性，离心得到血小板沉淀块，透射电镜下观察血小板的超微结构。结果：与空白组或模型组相比，大蒜素大剂量组（10mg/kg)、小剂量组（5mg/kg)均可显著抑制药物诱导的血小板聚集（P＜0．01），且大剂量组显著优于小剂量组（P＜0．05）；均可明显降低模型大鼠血浆TXB2的含量，降低TXB2／6－keto-PGF1α比值，大剂量组还显著升高血浆中6－keto-PGF1α水平（P＜0．05，P＜0．01）；可明显抑制血小板活化过程中超微结构的改变，且有一定的量效关系。结论：大蒜素可能通过抑制血小板聚集，抑制血小板活化时大量释放的活性肽TXA2、促进恢复TXA2／PGI2平衡，抑制血小板激活释放过程中超微结构的改变，从而对脑梗塞起治疗作用。     

The relational underpinnings of quality internal auditing in medical clinics in Israel

Internal auditing is a key mechanism in enhancing organizational reliability. However, research on the ways quality internal auditing is enabled through learning, deterrence, motivation and process improvement is scant. In particular, the relational underpinnings of internal auditing have been understudied. This study attempts to address this need by examining how organizational trust, perceived organizational support and psychological safety enable internal auditing. Data collected from employees in medical clinics of one of the largest healthcare organizations in Israel at two points in time six months apart. Our results show that organizational trust and perceived organizational support are positively related to psychological safety (measured at time 1), which, in turn, is associated with internal auditing (measured at time 2).     

Analysis of the circumstances at the end of life in children with cancer: Symptoms, suffering and acceptance

BACKGROUND: In an effort to improve the quality of life of children with cancer, this study analyzes the signs and symptoms at the end of life in such children. It is hoped that these data will contribute to the development of appropriate programs to address the challenges faced by these children. PROCEDURE: Between 1994 and 2000, 28 children died after treatment for cancer at Hamamatsu University Hospital, Japan. The circumstances, signs and symptoms at the end of life of these children were analyzed through their medical records. RESULTS: Of the 28 children, the underlying diseases were leukemia/lymphoma (LL group; n=11), brain tumors (BT group; n=7), and other solid tumors (OST group; n=10). Records showed poor appetite (100%), dyspnea (82.1%), pain (75.0%), fatigue (71.4%), nausea/vomiting (57.1%), constipation (46.4%) and diarrhea (21.4%) among these children. Anxiety was reported in 53.6% of the entire group of 28 children; however, no child in the BT group manifested anxiety. However, disturbance of consciousness was reported in all children in the BT group, which was significantly greater than in the other groups. Awareness, fear or acceptance of the imminence of his/her own death as indicated by verbal expression was reported in nine children (32.1%). CONCLUSIONS: Using the data obtained in the present study, we describe situations faced in the terminal care of children. It is important to address the problems revealed by this analysis in order to achieve improvements in both the physical and psychological care of children with terminal cancer.     

宁波普通高中教师职业压力、社会支持与亚健康躯体症状的典型相关分析

目的 探讨宁波市普通高中的教师心理压力,社会支持与亚健康状态的相关关系.方法 采用职业压力问卷、社会支持量表与亚健康躯体症状自评量表对随机抽取的128名宁波市普通高中教师进行相关关系分析.结果 当存在社会支持变量时,2组变量的典型相关系数达0.563,0.471( P <0.01).职业压力的增大与社会支持水平的减少都将导致教师亚健康躯体症状的增多.当撤去社会支持变量后,典型相关系数为0.497( P <0.01).典型变量ξ中"考试压力","工作负荷"与"职业期望"的因子负载分别增大为0.801,0.855,0.726.典型变量η中的"疲劳感觉"与"睡眠障碍"的因子负载分别增大为0.774,0.859.结论 社会支持水平在职业压力与亚健康躯体症状之间可能具有中介调节作用.     

Caring for the patient with fibromyalgia: the rehabilitation nurse's role.

Fibromyalgia (FM) is a chronic, potentially disabling, cluster of symptoms that manifests as pain for 3 months or more and pain with pressure on 11 of 18 tender points throughout the body. Because there is no known cause, and therefore, no cure, treatment focuses on the control or relief of symptoms. Many patients are referred to rehabilitation settings for physical or exercise therapy. While exercise is helpful in the control of the pain, stiffness, fatigue, sleep disorders, and mood changes, a holistic approach to treatment is more effective. Rehabilitation nurses provide major support for patients with FM. Validation of the patients' experiences is essential for achieving quality of life. Many patients have a history of being undertreated because of a lack of credibility and invisibility of the illness. This article provides background information about FM, summarizes the FM trajectory, reviews approaches to management, and discusses the role of rehabilitation nurses in a holistic approach to care of clients with FM.     

两种不同方法测定低水平压力支持通气时气道阻断压与自主呼吸时常规方法测定值的相关性分析

目的 拟比较以两种不同方法测定低水平压力支持通气（pressure support ventilation，PSV）病人的气道阻断压（P0．1）与自主呼吸时常规方法测定值的相关性。方法 12例机械通气病人，断开呼吸机自主呼吸时以常规方法测定P0．1得到P0．1-SB：在PSV水平为5cmH20，以常规方法和按压呼气末暂停键测定P0．1分别得到P0．1-PSV5和P0．1-PSV5eeo．分析后二者与前者之间的相关性。结果 P0．1-SB与P0．1-PSV5之间差异无显著性，P0．1-PSV5ee0分别小于P0．1-SB与P0．1-PSV5，差异有显著性；P0．1-PSV5eeo与P0．1-PSV5和P0．1-SB之间的相关系数均为0．97。结论 按压呼气末暂停键测定PSV水平为5cmH2O的P0．1值与常规方法测定的PSV水平为5cmH2O以及自主呼吸时的测定值相比，其值偏小,但前者与后二者之间具有良好的相关性。
