中药抗呼吸道合胞病毒实验研究进展

中药具有高效低毒的特点,分别从抗呼吸道合胞病毒(RSV)复方和单味中药提取物2个方面,总结中药对RSV的实验抑菌作用及其作用机制,期待为临床治疗提供理论依据,并为进一步挖掘和深入研究中药抗病毒成分提供新的思路。同时指出了单味中药提取物虽然可以较为清晰地说明治疗机制和作用靶点,但目前多数尚停留在物质分析、鉴定和少数动物细胞实验阶段。

Implementing remote triage in large health systems: A qualitative evidence synthesis

Remote triage (RT) allows interprofessional teams (e.g., nurses and physicians) to assess patients and make clinical decisions remotely. RT use has developed widespread interest due to the COVID‐19 pandemic, and has future potential to address the needs of a rapidly aging population, improve access to care, facilitate interprofessional team care, and ensure appropriate use of resources. However, despite rapid and increasing interest in implementation of RT, there is little research concerning practices for successful implementation. We conducted a systematic review and qualitative evidence synthesis of practices that impact the implementation of RT for adults seeking clinical care advice. We searched MEDLINE®, EMBASE, and CINAHL from inception through July 2018. We included 32 studies in this review. Our review identified four themes impacting the implementation of RT: characteristics of staff who use RT, influence of RT on staff, considerations in selecting RT tools, and environmental and contextual factors impacting RT. The findings of our systemic review underscore the need for a careful consideration of (a) organizational and stakeholder buy‐in before launch, (b) physical and psychological workplace environment, (c) staff training and ongoing support, and (d) optimal metrics to assess the effectiveness and efficiency of implementation. Our findings indicate that preimplementation planning, as well as evaluating RT by collecting data during and after implementation, is essential to ensuring successful implementation and continued adoption of RT in a health care system.     

Successful integration of the histology core laboratory in translational research

Abstract

In a diagnostic setting, the histology laboratory is a key resource for production of quality tissues so the pathologist can make an appropriate diagnosis. In a research setting, the histology laboratory is a valuable resource in providing an excellent quality product for publications and grants for the investigator. Optimal collaboration with research investigators requires that histotechnologists recognize the diverse challenges and opportunities in research. This paper emphasizes the importance of positive interaction with researchers, optimizing professional service for these clients and recognizing key services of histology laboratories in a research setting to maximize success.     

Étude qualitative de l’expérience de la formation en hypnose clinique pour les professionnels de santé

ObjectiveTraining in clinical hypnosis leads to important transformations in healthcare professionals, in their professional practices as well as in their personal lives. The objective of this study was to explore how health professionals experience the transformations that result from such a training.MethodSemi-structured interviews with health professionals from France and Europe were conducted. The qualitative method used was Interpretative Phenomenological Analysis. Purposive sampling required to include participants from different professions, experience and regions of origin. They had already completed training in clinical hypnosis at different teaching institutions.ResultsTen participants were included. The analysis showed four meta-themes of experience. First, it revealed participants’ motivations for training in clinical hypnosis as one's desire to improve one's practice, leading to extraordinary discoveries, at a particular timing in their life. Second, participants described that hypnosis sometimes set the ground for a relationship verging on the more “intimate”, therefore requiring greater caution so as not to disrupt the patient/healthcare professional relationship. Third, some participants experienced unforeseen personal fulfilment, better self-regulation of emotions and improved quality of life as well as greater comfort at the workplace. Finally, this study shed light on two limitations of training in clinical hypnosis as it can sometimes generate stress for the participants and/or result in bring about potential harmful effects: one of the risks being that the trainer might cross some ethical lines.DiscussionThe level of personal change experienced by the participants is similar to some changes induced by personal psychotherapy. For several participants, issues of power and vulnerability in the relationship using hypnosis were associated with a feeling of instability during the training. In hypnosis, the management of an asymmetrical relationship involves a two-way risk: vulnerability of the hypnotized person to the all-powerful relationship of their therapist as well as destabilization of therapists by the reduction of power asymmetry during hypnotic work with their patients.
