Evaluation of bedside blood glucose monitoring by the phlebotomy team in an acute general care hospital

A feasibility study was undertaken to evaluate laboratory phlebotomists performing bedside glucose monitoring (BGM) over a 3-month period on a medical and surgical floor. Specific questions included: feasibility of providing testing on a 24-h basis, accuracy, appropriate utilization, effect on patient care, and an analysis of cost. In all, 1975 tests were performed on 114 patients. BGM results were within 15% of the laboratory's result 97% of the time. Patient and physician satisfaction was high. Although the cost of BGM is slightly higher than a laboratory glucose test, its use appeared to reduce the length of hospital stay by 0.47 days. Practical information on initiating a highly successful BGM program is provided.

放射性碘标记的抗肺癌单克隆抗体在载瘤裸鼠体内的代谢

放射性碘标记的抗人肺癌单克隆抗体2E3和6DI注入载人肺癌移植瘤裸鼠体内,静脉血放射性-时间曲线符合二室开放模型;血放射性清除半减期为3.4d,表观分布容积636ml/kg;标记抗体在体内的脱碘率为18.6％,脱落的放射性碘绝大部分从尿排出。腹腔给药吸收快,半吸收期2.08h,生物利用度89％。~(125)I标记的单克隆抗体注射后1～3d,放射性主要分布在肿瘤、血、肝、脾中,其次为肺、肾、胃、小肠;此后,血和正常组织的放射性下降,肿瘤中的放射性较高。~(131)I标记的单克隆抗体能使移植瘤清晰显像。     

Alcohol controls and Aboriginal society: The effects of the Northern Territory restricted areas legislation

The “restricted areas” provisions of the Northern Territory Liquor Act constitute a preventative policy aimed at reducing the effects of alcohol abuse, particularly on Aboriginal communities. Under the provisions, communities can apply to be declared “dry” or semi-restricted with respect to liquor. Since their inception in 1979, the provisions have given rise to continuing controversy. This paper addresses some of the issues associated with the controversy. Patterns of alcohol consumption on “dry”, semi-restricted and unrestricted communities are compared, and the incidence of apprehension for public drunkenness before and after restricted area declarations is examined. The paper also discusses the provisions under which vehicles implicated in acts of illicit “grog-running” are forfeited to the NT Government. It is concluded that the restricted area provisions are associated with reduced levels of alcohol consumption and apprehensions for drunkenness, and are therefore beneficial in outcome. However, it is also argued that at present the provisions are flawed in that, while some aspects serve to promote community control over alcohol consumption, other elements have the effect of undermining community control and responsibility.     

婴儿母乳喂养与学龄前肥胖症关系的病例对照研究

①目的　探讨婴儿期母乳喂养行为与学龄前期单纯性肥胖症发生之间的关系。②方法　对 180 0名4～ 5岁儿童的婴儿期母乳喂养情况及其体质指数 (BMI)、发育情况等进行调查 ,分析母乳喂养类型和持续时间与学龄前肥胖症发生之间的关系。③结果　单因素分析发现 ,4个月内只喂母乳、主要喂母乳、母乳与配方奶量基本相同、主要喂配方奶、只喂配方奶者 4～ 5岁时肥胖发生率分别为 12 .6 3% ,13.0 4 % ,16 .98% ,18.18% ,30 .0 0 % ;儿童母乳喂养持续时间 0 ,<1,1～ 3,4～ 6 ,7～ 9,>9个月者 4～ 5岁时肥胖发生率分别为 2 9.4 1% ,30 .0 0 % ,33.33% ,17.2 4 % ,13.92 % ,12 .2 2 % .母乳喂养类型和持续时间不同的儿童学龄前期单纯性肥胖症发生率不同 ,差异有显著性 (χ2 =10 .4 0 7,P <0 .0 5 ;χ2 =2 0 .90 3,P <0 .0 0 1)。多因素Logistic回归分析发现 ,4个月内喂配方奶量越多 ,肥胖发生率越高 (OR =1.12 0 ) ;母乳喂养持续时间越长 ,肥胖发生率越低 (OR =0 .782 )。④结论　婴儿母乳喂养对学龄前期肥胖症的发生有预防作用 ;婴儿期应提倡母乳喂养 ,并尽可能延长母乳喂养时间至 9个月以上。

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.     

State and output feedback design for robust tracking of linear systems with rate limited actuators

A design technique (Control of Uncertain Systems with Bounded Inputs, Tarbouriech S, Garcia G, (Eds), Lecture Notes in Control and Information Sciences, vol. 227 , Springer: Berlin, 1997; 173–186) recently proposed for stabilization of a linear system with rate‐limited actuators is utilized to design feedback laws that cause the system output to track a desired command signal. This design technique combines two design techniques recently developed for linear systems with position limited actuators, piecewise‐linear LQ control (Automatica, 1994; 30 : 403–416) and low‐and‐high gain feedback (IEEE Trans. Automat. Control, 1996; 41 : 368–378), and hence takes advantage of both design techniques, while avoiding their disadvantages. In the case that only the output is available for feedback, the performance of the state feedback law is preserved by the use of a fast observer. An open‐loop exponentially unstable fighter aircraft is used to demonstrate the effectiveness of the proposed control design method. Copyright © 2002 John Wiley & Sons, Ltd.
