基于HACCP理论构建基层药品不良反应培训模式初探

目的探索基层药品不良反应培训模式。方法通过引入HACCP理论,对当前基层药品不良反应培训过程中潜在的风险和危害进行识别、分析并采取有效措施加以预防控制。结果从培训师资、培训内容、培训方式等方面初步构建了基层药品不良反应培训模式。结论在培训过程中,注重抓住关键控制点,即培训内容要结合实际、培训对象要分层次、培训方式要有创新、培训效果要有长期性。     

Animal models for neonatal diseases in humans

The development of vaccines for infants and young children requires the use of animal models at various stages of preclinical development. Animal models are being used to assess the quantity and quality of the immune response, onset and duration of the response, induction of systemic versus local immunity, protection against challenge infection for the assessment of vaccine efficacy, as well as safety and toxicity of the vaccine formulation itself. A variety of animal models are available, each with its own specific advantages and disadvantages. Here, we review the most common animal models for preclinical vaccine development for human infants.     

Supervision: Critical Reflection for Transformational Learning,Part 1

Rooted in medicine and psychology, genetic counseling is a unique practice with a defined set of skills. Training is guided by practice-based competencies that define the requisite skills of an entry-level practitioner. Practicing genetic counselors with expertise in a variety of medical settings provide direct supervision that guides student development. In this article, we provide background on the history of genetic counseling, the model of practice, accreditation and certification standards, and an overview of clinical supervision as well as a review of supervision literature specific to the field.     

Effectiveness of Community Intervention in Improving Bone Health Behaviors in Older Adults

An 8-week, bone-health community program addressed risks/lifestyle changes within the Health Belief Model and Theory of Reasoned Action frameworks in a randomized format (treatment group n = 35; control group n = 34). Median week 1 values for calcium (control, 963 mg; treatment, 1023 mg) and vitamin D (81 IU both groups) were below recommendations, increasing throughout the program for both control (1023 mg calcium, 128 IU vitamin D) and treatment (1005 mg calcium, 122 IU vitamin D) groups. There was limited response to the exercise outcome variables, with many not participating in that section of the program. Psychosocial variables were positive for both control and treatment groups at week 1, with no significant difference at postintervention. Regression analysis indicated that those with a positive attitude about calcium intake and belief that they could choose calcium-fortified foods were more likely to have higher calcium intake. Intention to exercise was modified by peer and family support. Community-based programs can translate and use clinical trial key topics and outcomes, but participation bias makes impact results difficult to interpret the effectiveness of the program.     

Animal and human models for sepsis

Several preclinical models for sepsis have been used in the last decades to successfully unravel the pathophysiologic processes during sepsis. Furthermore, these models for sepsis revealed promising immunomodulating agents for the treatment of sepsis. Nevertheless, several clinical trials evaluating the efficacy of these new anti-inflammatory agents in septic patients showed disappointing results. In this article the advantages and disadvantages of different models for sepsis are discussed. Most models for sepsis lack an infectious focus. Importantly, investigations studying the effects of several immunomodulating strategies have demonstrated strikingly opposite results when using models for sepsis lacking an infectious focus and when using models for sepsis with a more natural route of infection. These differences will be discussed in this article. In general, it is advised to use a combination of models to test a new therapeutic agent, before starting a clinical study evaluating this new therapy.

骨应力性塑形改建的研究及其对新兵基础训练的指导意义

分组模拟训练的２８８只兔股骨标本病理观察及扭断试验结果表明,较大强度和时限训练的主导作用是加速骨塑形改建,增强抗骨折能力。分３组经３种方法训练的１８０只大鼠的胚骨上段病理切片及电镜观察表明,强化循环训练组的改建完成率（４１．７％）高于其它两组（２６．１％,２１．９％）,而应力性骨折发生率（１１．５％）则低于其它两组（２２．９％,１８．８％）。对１１２９名新兵１２周基础训练的前瞻性流行病学调查证实,下肢长管状骨经历约９周的应力性塑形改建期,训练的第２、７周出现的应力性骨折高发的双峰现象可随训练强度与时限的加大或减少,而提前或延迟出现。在训练中采用“强化循环训练法”将加速骨的塑形改建及降低应力性骨折发生率。
