Process evaluation of implementation strategies to reduce potentially inappropriate medication prescribing in older population: A scoping review

ObjectivesSeveral implementation strategies can reduce potentially inappropriate medication (PIM) prescribing. Although use of PIMs has declined in recent years, it remains prevalent. Various strategies exist to improve the appropriateness of medication use. However, little is known about the processes of these different implementation strategies. This scoping review aims to investigate how the process evaluation of implementation strategies for reducing PIM prescribing in the older population has been studied.MethodsWe searched for process evaluations of implementation strategies for reducing PIM prescribing in PUBMED, SCOPUS and Web of Science published between January 2000 and November 2019 in English. We applied the following inclusion criteria: patients aged ≥65 years, validated PIM criteria, and implementation process evaluated. The review focuses on decision support for health care professionals. We described the findings of the process evaluations, and compared the authors’ concepts of process evaluation of the included publications to those of Proctor et al.( 2010).ResultOf 9131 publications screened, 29 met our inclusion criteria. Different process evaluation conceptualizations were identified. Most process evaluations took place in the initial stages of the process (acceptability, adoption, appropriateness, and feasibility) and sustainability and implementation costs were seldom evaluated. None of the included publications evaluated fidelity.Multifaceted interventions were the most studied implementation strategies. Medication review was more common in acceptability evaluations, multidisciplinary interventions in adoption evaluations, and computerized systems and educational interventions in feasibility evaluations. Process evaluations were studied from the health care professionals’ viewpoint in most of the included publications, but the management viewpoint was missing.DiscussionThe conceptualization of process evaluation in the field of PIM prescribing is indeterminate. There is also a current gap in the knowledge of sustainability and implementation costs. Clarifying the conceptualization of implementation process evaluation is essential in order to effectively translate research knowledge into practice.     

Disability policies in Japan and Sweden: A comparative perspective

The aim of this article was to compare disability policies in Japan and Sweden. Social protection in the two countries has taken different directions. Policy orientation in Japan is ‘productivist’, paternalistic, family-oriented, and firmly involves medical expertise in assessing eligibility to disability services. In practice, social services in Japan is the result of negotiations between social service staff at the local level, volunteer agencies and private contributors. In Sweden, social services, were established as social rights, financed by public money, and distributed by public sector agencies or out-sourced to private providers. Such support, assessed by social workers, were intended to facilitate daily life and achieve “good living conditions”. While Japan's disability services are characterized by the medical model and improving physical accessibility, practices in Sweden are based on a social relational model perspective of disability services combined with increasing ‘deservingness ethics’.     

Aligning Developmental and Processing Accounts of Implicit and Statistical Learning

A long‐standing question in child language research concerns how children achieve mature syntactic knowledge in the face of a complex linguistic environment. A widely accepted view is that this process involves extracting distributional regularities from the environment in a manner that is incidental and happens, for the most part, without the learner's awareness. In this way, the debate speaks to two associated but separate literatures in language acquisition: statistical learning and implicit learning. Both fields have explored this issue in some depth but, at present, neither the results from the infant studies used by the statistical learning literature nor the artificial grammar learning tasks studies from the implicit learning literature can be used to fully explain how children's syntax becomes adult‐like. In this work, we consider an alternative explanation—that children use error‐based learning to become mature syntax users. We discuss this proposal in the light of the behavioral findings from structural priming studies and the computational findings from Chang, Dell, and Bock's (2006) dual‐path model, which incorporates properties from both statistical and implicit learning, and offers an explanation for syntax learning and structural priming using a common error‐based learning mechanism. We then turn our attention to future directions for the field, here suggesting how structural priming might inform the statistical learning and implicit learning literature on the nature of the learning mechanism.     

孕烷X受体与炎症反应及中药干预机制研究进展

孕烷X受体(Pregnane X receptor,PXR)是核受体家族成员之一,可被多种内源性和外源性物质激活。PXR通过诱导药物代谢酶和转运体,在肝脏、肠道、皮肤和血管内皮中发挥重要的解毒作用。此外,PXR还具有调节糖脂代谢、胆固醇代谢、胆红素和胆汁酸代谢、免疫炎症反应等功能。研究证实,PXR已被公认为多种炎症性疾病的有效药物干预靶点,如炎性结肠炎、坏死性肠炎、肝炎、皮炎、糖尿病等。多种中药或其活性成分可以作为PXR受体激动剂通过核因子B(NF-κB)和尾部相关同源盒转录因子2(Cdx2)通路干扰炎症反应,如虎杖、木蝴蝶、黄芩、黄连、丹参、白芷、人参、香附、五味子、高良姜等。本文综述了近年来PXR调节炎症反应的最新研究成果以及中药激活PXR干预炎症反应的机制,以期为今后的研究提供参考。

一种度量细胞网络结构的方法

文题释义： 复杂网络：是指具有自组织、自相似、小世界、无标度中部分或全部特征的网络。小世界效应和无标度特性是复杂网络最显著的特点。小世界是指网络具有大的簇系数和较小的平均路径长度，无标度是指网络节点的连接度分布服从幂律分布。 细胞网络：在多细胞生物体中，单个细胞除了完成自身功能外，各个细胞间的通讯联络是必不可少的，如维持生物体的生长发育、各种生理活动的协调等。如果将每个细胞抽象为一个节点，每两个细胞间的通讯抽象为一条边，那么众多细胞及其之间的通讯将抽象成为一个巨大的细胞网络。 背景：在多细胞组成的生物体社会中，细胞之间的通讯必不可少。众多细胞之间相互通讯、相互联系，形成了一个复杂的细胞网络结构。对细胞网络结构相关属性值进行度量和评价，显得极其重要。 目的：基于复杂网络，提出了一种细胞网络结构的度量方法。 方法：结合文献研究及实际应用，搭建细胞网络结构的度量框架，分别从细胞节点的度、细胞网络的度分布、细胞网络的平均路径长度、细胞网络的簇系数等方面对细胞网络结构进行度量。以某小型实验为例，进行了实例验证。 结果与结论：细胞网络的度分布中，绝大部分细胞节点的度值比较小，只有较少量细胞节点的度值较高。细胞网络中细胞节点的度分布P(k)的幂律分布特点越是明显，则此细胞网络结构越是合理，细胞网络越正常；同时，许多细胞网络结构具有较小的平均路径长度。细胞网络的簇系数越大，表明该细胞网络具有较高的聚集特性。一般情况下，细胞网络结构越“紧密”，细胞网络结构的“集团化”特性越明显，细胞网络越正常。 ORCID: 0000-0002-2483-032X(张雨) 中国组织工程研究杂志出版内容重点：干细胞；骨髓干细胞；造血干细胞；脂肪干细胞；肿瘤干细胞；胚胎干细胞；脐带脐血干细胞；干细胞诱导；干细胞分化；组织工程
