Drug Education: Supporting Parents to Support Children

Such research evidence as exists on effective drug strategies in prevention and education draws attention to the importance of involving parents along with other community agencies and school governors. Much depends nevertheless on the way in which 'involvement' is interpreted and the assumptions that are made about parents' knowledge of drugs and drug education as well as their attitudes to drug issues. As the age of initial experimentation and contact with drugs continues to fall, the importance of enskilling parents to support drug education programmes for 5 year olds and upwards continues to rise. This paper reports the first wide ranging survey of parents' knowledge of drugs and drug issues across an entire English county embracing younger as well as older children. The need for more coordinated, informed and systematic guidance to parents is established.     

Elements of psychological support in nursing care

The paper presents the results of a pilot study which involved 50 nurses from several departments of internal medicine of The State Clinical Hospital of the Collegium Medicum, Jagiellonian University in Cracow. The results are based on the Statement Response Questionnaire. They show that the most common responses of the nurses in the face of anxiety expressed by patients are cheering up the patient, collecting information about the symptom, and offering explanation of the symptom. The least common responses included expressing one's own positive emotions and showing empathy towards the patient.     

天然水中三卤甲烷前体活性结构的研究

通过实验证实，可用腐植酸（ＨＡ）代表天然水中三卤甲烷（ＴＨＭｓ）的前体。单一模拟化合物（含一个活性空位碳原子的间苯二酚，三个活性空位碳原子的间苯三酚，及甲基酮类化合物的丙酮酸钠）氯化后氯信形成的规律与氯化ＨＡ的不一致。而间苯二酚与丙酮酸钠的混合物（１：４Ｗ／Ｗ）能很好地反映出ＨＡ中活性结构的特性。为今后研究ＴＨＭｓ的形成提供了一个可资定量比较的ＴＨＭｓ前体。     

Asymptomatic autoimmune chronic active hepatitis in a male adolescent

We report a 12-year-old boy presenting with smooth muscle antibody-positive auto-immune chronic active hepatitis. Suspicion of the diagnosis arose after a routine blood test which revealed abnormal liver function tests. In spite of the presence of cirrhosis and patchy necrosis on liver biopsy, our patient never showed any clinical feature of impaired liver function. This observation demonstrates that auto-immune hepatitis may exist for a long time before clinical symptoms appear and probably explains why some cases of auto-immune hepatitis finally present as fulminant liver failure.     

Moving beyond empiric continuous positive airway pressure (CPAP) trials for central sleep apnea: a multi-modality titration study

There is no universally accepted method to determine effective therapy for central sleep apnea (CSA). Continuous positive airway pressure (CPAP) applied acutely most often does not eliminate apneas and hypopneas. We hypothesized that the application of two or more therapeutic modalities after the diagnostic phase of polysomnography, a multi-modality titration study (MMTS), would identify a successful CSA treatment more often than a standard split-night study (SNS) and obviate the need for additional polysomnograms to determine a successful therapy. We retrospectively analyzed polysomnograms of patients diagnosed with CSA at our Sleep Disorders Center. We defined a therapy trial that resulted in an apnea–hypopnea index < 10 with at least one treatment modality as a therapeutic success. One hundred fifteen patients with CSA were studied. Sixty-six patients (57.4%) underwent a SNS, and 49 patients (42.6%) underwent a MMTS. SNS yielded only 8/66 (12.1%) successes on the first night, whereas a MMTS yielded 19/49 (38.8%) successes (p = 0.001, two-tailed Fishers exact). Patients who underwent a SNS eventually had similar rate of success as patients studied with MMTS (60.6 vs 63.3%, NS), but required more testing. Adaptive servo-ventilation was the most successful modality tested, yielding 36/46 (78.3%) successes. Trials of additional modalities following a failed trial of CPAP often produce a successful option that may guide therapy in patients with CSA. This approach may lead to establishing the diagnosis and treatment plans faster, while reducing unnecessary testing.

同伴支持、父母支持和青少年自我价值感初探

目的：探讨实际的同伴支持、感知到的同伴支持、感知到的父母支持、对同伴支持的重要性评价、对父母支持的重要性评价和自我价值感之间的关系。同时也考察了青少年的同伴接受性。方法：用社会测量法和自我报告法对285名青少年进行集体测试。结果：①社会测量法表明青少年也可以被分为受欢迎的、被拒绝的、被忽略的、和有争议的；②感知到的同伴／父母支持和自我价值感之间存在显著正相关；高低实际同伴支持两组被试在感知到的同伴支持上存在显著差异。但在自我价值感上不存在显著差异；（固在所有被试中，只有对初三学生来说，对同伴／父母支持的重要性评价在感知到的同伴／父母支持和自我价值感之间起到调节作用。结论：感知到的同伴／父母支持可以用来预测青少年的自我价值感：对初三学生来说，对同伴／父母支持的重要性评价可以在感知到的同伴／父母支持和自我价值感之间起到调节作用。     

An Implantable Aortic Valvo-pump for Destination Therapy

To investigate the possibility of a long-term applicable left ventricular assist device, a 23 mm outer diameter and 31 g weight implantable aortic valvo-pump was developed. It consists of a rotor and a stator; the rotor has a driven magnets assemble and an impeller, the stator has a motor coil with iron core and a outflow guide vane. The device locates the position of aortic valve, delivers the blood directly from left ventricle to aorta. Neither connecting conduits nor “bypass” circuits are necessary. Therefore, the device has promisingly better antithrombogenicity than other heart pumps. In hemodynamic testing, the pump can produce a blood flow of 7 l/min volume with 50 mmHg pressure increase at 15,000 rpm rotating speed, and at zero flow rate the pump can maintain a diastolic pressure over 80 mmHg at same rotating speed. For further studies the blood compatibility and the durability of the device are of most importance.
