Framing the child at risk

Risk Assessment Reports are one form of accounting practice which delineate the space of risk considered in a child abuse neglect investigation. The paper analyses two Risk Assessment Reports, contrasting what is reported, what is directly observed and what is hypothesized and implied by child protection practitioners during the assessment of risk. From an analysis of these two reports (each 4 – 5 pages long), the paper identifies the rhetorical strategies and their realizations used by two practitioners in framing the child at risk. The paper problematizes the tension between the institutional need to constrain the exercise of professional judgement through Risk Assessment Models, and the extent to which practitioners actually localize the framing of risk to specific areas of investigation.     

论我国医患冲突成因及和谐关系构建

目前我国医患之间的矛盾与冲突，实质上是新时期我国社会矛盾在卫生工作中的具体表现，反映了社会群体在经济状况、价值取向、角色意识、道德水平、法律法规等多方面的矛盾与冲突。和谐医患关系应是构建我国和谐社会的内容之一。和谐医患关系的构建需要完善的社会医疗保障体系建立、国家卫生行政管理加大、财政补偿合理投入、医疗服务质量提高、医学知识教育普及与提高、媒体理性传播、社会大众道德控制水平提升，法律法规完善等全方位的努力，有赖于医事主体双方及全社会的关注与通力改善。     

Making clinical decisions for dental care: concepts to consider

Clinical decisions are often made with incomplete information, yet patient care decisions are made every day. Patients vary clinically, uncertainty exists in diagnostic and prognostic information, and many preventive and treatment alternatives have not been formally assessed for their effectiveness. Because scientific information will never answer all clinical questions, clinical decisions are partially based on probabilistic information.
This paper describes how to apply clinical decision making to diagnosing and managing dental caries and periodontal diseases. By using explicit information to quantify probabilities and outcomes, clinical decision making analyzes decisions made under uncertain conditions and the uncertain impact of clinical information.
Clinical decision making incorporates concepts for preventing, diagnosing and treating dental caries and periodontal diseases: risk assessment, evidence-based dentistry, and multiple oral health outcomes. This information can serve as a tool for clinicians to augment clinical judgment and expertise.     

医患诚信现状剖析

近几年来,诚信缺失现象大量涌现,信用问题日益凸现,医疗行业也深陷其中。医患诚信问题严重地挫伤了医患感情,医患间不信任情绪不断加深。关注和研究我国医患关系中的诚信伦理问题已刻不容缓。     

From Innumeracy to Insight: The Uncertainty of Help versus Harm in Treatment of Asymptomatic Aortic Aneurysms

There is insufficient evidence that the surgical treatment of asymptomatic infrarenal aneurysms > 5.5 cm. is beneficial to patients. This is the result of serious complications of aneurysm surgery and the dearth of information from randomized trials. Based on evidence from the literature we defined scenarios and translated data into natural frequency trees to improve understanding of the uncertainty of help versus harm due to treatment of aneurysms. Our analysis shows that the majority of patients can expect little on longevity from surgery while they are at risk of dying from surgery or suffering from serious morbidity. We conclude that, as long as uncertainty persist, patients should be treated in hospitals that can show very low surgical mortality and major morbidity rates. To further resolve the problem of uncertainty randomized trials for larger aneurysms should be performed. Important issues to discuss are the lower and upper limits of the diameter of the aneurysms and the age and risk profiles of the patients to be included in such trials.     

Utility of the Brief Symptom Inventory in the Assessment of Psychological Distress

Introduction People with intellectual disabilities are now acknowledged to be susceptible to the full range of mental health disorders. This acknowledgement has resulted in the need to develop and evaluate instruments for the assessment and detection of mental health problems. This research evaluates the use of the Brief Symptom Inventory (BSI) with 200 people with mild intellectual disabilities representing community, clinical and forensic populations. Results and conclusions Results illustrate the reliability of the BSI for each of the groups and demonstrates how the Positive Symptom Total (PST) index effectively discriminates between study groups. Case rates for each group are provided. The study illustrates that the BSI could be employed as a brief multitrait assessment instrument and as a treatment outcome measure with people with an intellectual disability.     

六经气津互化论

气与津皆生于水谷,气生于水,水化于气,津即为水。由于气津互化的密切关系,故任何一方的改变,都会影响到另一方,即所谓水化于气,亦能病气;气生于水,亦能病水。因此,太阳经气可概括为两大功能,即卫外和气化,是由气津互化而体现的;阳明气津之间,表现为相互制约;少阳经的气津互化,关系到少阳气机的条达舒畅及三焦水道的通调运使;太阴脾气的健旺,可使津液化生有源;少阴心肾精血充沛,滋养有时,才可使心肾之气化生有源;而厥阴之气的条达顺畅,又可维持津液代谢的平衡状态。     

Muscle mass index in haemodialysis patients: a comparison of indices obtained by routine clinical examinations.

BACKGROUND: Measurement of muscle mass is useful for evaluating protein nutritional status. Various methods for estimating muscle mass in haemodialysis patients have recently been developed. METHODS: The validity of the estimate of creatinine production calculated with the creatinine kinetic model (CKM) was examined in 46 haemodialysis patients by comparing it with the actual creatinine production, this being determined from the sum of creatinine appearing in the dialysate and the estimated metabolic degradation. The correlation of various other muscle mass indices with creatinine production was also investigated in these patients. RESULTS: The estimate of creatinine production using CKM was significantly correlated with creatinine production calculated from the spent dialysate plus an estimate for the extra-renal creatinine degradation (r=0.90, P<0.001). A Bland-Altman analysis revealed that the mean prediction error for the estimate of creatinine production by CKM was +0.10 g/day and the limits of agreement were +0.34 to -0.14 g/day. The cross-sectional area of the thigh muscle measured by computed tomography (CT) was also significantly correlated with creatinine production (r=-0.86, P<0.01). In contrast, the correlations of 3-methylhistidine production measured in the spent dialysate, the mid-upper arm muscle circumference and the skeletal muscle mass estimated by an anthropometric prediction model with creatinine production were lower (r<0.82). CONCLUSION: Creatinine production calculated using CKM and CT measurement of thigh muscle area are valid methods for estimating muscle mass during routine clinical examinations of haemodialysis patients.     

核酸及核苷酸用于营养及免疫调节治疗的早期卫生技术评估

目的 评价核酸或核苷酸用于临床营养支持和免疫调节治疗的安全性、有效性和经济学价值。方法 检索中国生物医学文献数据库、Cochrane图书馆、MEDLINE光盘数据库、EMBASE光盘数据库,并联机检索SCI数据库,鉴定有关随机对照试验(RCTs),采用RevMan4.l进行Meta-分析。结果 纳入46个随机对照试验,涉及核酸/核苷酸用于肠内营养支持、婴儿营养、免疫调节治疗。18个研究报告了含核苷酸组分的免疫增强型肠内营养对外科术后和危重症患者预后的影响,合并分析发现免疫营养对患者感染率、住院时间和费用有肯定意义。发现1个报告在母乳代用品中加入核苷酸对婴儿免疫功能影响的研究,但报告对临床结局无明显影响。27个对“免疫核酸”用于免疫调节治疗的随机对照试验均为低质量研究,合并分析无法肯定iRNA的临床价值。结论 在外科术后患者应用免疫肠内营养制剂可降低感染率、缩短住院时间并可能减少住院费用,但不能确定作为组分之一的核苷酸的作用。尚无证据支持在母乳代用品中添加核苷酸具有临床意义。不能肯定免疫核酸是否具有免疫调节作用,亦未发现核酸在延缓衰老、改善老年人健康状况方面的可用证据。建议对核酸、核苷酸用于营养支持治疗和免疫调节治疗进行进一步研究,严格规范“核酸营养品”的宣传和应用。     

Sex effects in defensive behavior: Baseline differences and drug interactions

Female rats consistently show a pattern of differences in defensive behaviors compared to males which parallel the effects of exposure to a nonpainful threat stimulus (cat or cat odor) in the same tests and measures. These indications of greater defensiveness for females are particularly common in situations involving potential, as opposed to actual and present, threat, a factor which probably also reflects ceiling or floor effects in situations involving very intense defensiveness. In addition, pharmacological studies indicate sex differences in the effects of selective serotonin (5-HT) receptor agonists and antagonists on defensive responding. These findings indicate that sex effects must be considered in studies of the pharmacological control of defensive behaviors, and suggest that responsivity to sex effects may be an additional criterion for the suitability of animal models of anxiety.
