  The NHS Long Term Plan has a prevention focus and ambition to support patients to self-manage disease through improving health behaviours. An essential requirement of self-management is behaviour change, but many practitioners have not been trained in skills to support behaviour change. 'Healthy Conversation Skills' (HCS) training was developed at the University of Southampton for this purpose. This article reports on a pilot study that aimed to assess the feasibility of primary care practitioners adopting HCS in their routine practice. It describes their experiences and level of competence post-training.
 
  Health Education England (Wessex) commissioned HCS training for 18 primary care practitioners. Fifteen of these practitioners were subsequently observed in their consultations at one or two time points; face-to-face semi-structured, reflective feedback interviews were conducted immediately following the observations. Practitioners' HCS competence was assessed from the observations and interviews using a the prevention agenda by supporting disease self-management, and hence of addressing today's epidemic of lifestyle-related conditions.
 HCS are acceptable to primary care practitioners, can be readily adopted into their routine consultations and are a helpful strategy for supporting patients to make changes. HCS training has the potential to be a sustainable, scalable and effective way of contributing to the prevention agenda by supporting disease self-management, and hence of addressing today's epidemic of lifestyle-related conditions.The antimicrobial and anticaries effects of CaneCPI-5 were evaluated. Ninety bovine enamel samples were treated for 60 s with either phosphate-buffered-saline (PBS), 0.12% chlorhexidine (CHX), 0.05 mg ml-1 CaneCPI-5, 0.1 mg ml-1 CaneCPI-5 or 0.5 mg ml-1 CaneCPI-5. They were incubated with inoculum (human saliva + McBain's saliva) for the first 8 h. From then until the end of the experiment, the enamel was exposed to McBain saliva with sucrose and, once a day, for 5 days, they were treated with the solutions. At the end of the experimental period, resazurin and viable plate count assays were performed. Enamel demineralization was also measured. All concentrations of CaneCPI-5 and CHX significantly reduced the activity of biofilms compared with PBS. For viable plate counts, all treatments similarly reduced the lactobacilli and total streptococci; for the mutans streptococci, 0.05 mg ml-1 CaneCPI-5 performed better than CHX. All CaneCPI-5 concentrations significantly reduced the integrated mineral loss. This study represents the first step regarding the use of CaneCPI-5 within the concept of acquired enamel pellicle and biofilm engineering to prevent dental caries.
  Entrustable professional activities (EPAs) provide a novel approach to support teachers' structured professionalization and to assess improvement in teaching competence thereafter. Despite their novelty, it is important to assess EPAs as a construct to ensure that they accurately reflect the work of the targeted profession.
 
  The co-creation of an EPA framework for training and entrustment of small-group facilitators has been discussed in the literature. Although a rigorous design process was used to develop the framework, its content validity has not been established yet.
  A modified Delphi technique was used. Three survey rounds were conducted from December 2019 to April 2020. Expert health professions educationalists were recruited using purposive sampling and snowball techniques. In Round 1, a rubric consisting of seven items was used to assess the quality of nine pre-designed EPAs. In Round 2, competencies required to perform the agreed-upon EPAs were selected from 12 competencies provided. In Round 3 specification, required competencies, and entrustment resources. Program developers, administrative bodies, and teaching staff may find this EPA framework useful to structure faculty development, to entrust teachers, and to support personal development.
 The final framework delineates three EPAs for small-group facilitation and their associated sub-activities. The full description of each EPA provided in this article includes the title, context, task specification, required competencies, and entrustment resources. Program developers, administrative bodies, and teaching staff may find this EPA framework useful to structure faculty development, to entrust teachers, and to support personal development.Enteropathogenic Escherichia coli E2346/69 (EPEC) has caused foodborne outbreaks worldwide and the bacterium forms antimicrobial-tolerant biofilms. The anti-biofilm formation of various components of essential oils extracted from selected medicinal plants were investigated and tested on EPEC and wild strains of E. coli. Oils extracted from the family Asteraceae and their major common constituents at 0.031 and 0.062% (V/v) were found to significantly inhibit biofilm formation without affecting the growth of planktonic cells. In addition, three plants belonging to this family (Artemisia herba alba, Artemisia campestris and Artemisia absinthium) played important roles in the antimicrobial activity. Interestingly, their essential oils reduced the ability of E. coli (the EPEC and K12 strains) to form a biofilm. The crystal violet reduction assay showed that the plant extracts tested reduced biofilm formation with the inhibition of bacterial attachment up to 45% for EPEC and 70% for E. coli K-12 after 24 h treatment at 0.62 mg ml-1, demonstrating that Artemisia oils had a high anti-biofilm activity on the bacteria tested. The results indicate that the locus of enterocyte effacement (LEE) acquired by horizontal transfer promotes the formation of the attaching and effacing (A/E) lesion and increases the capacity of the photogen strain (EPEC) to form a biofilm. The chemical composition of the volatile compounds was obtained by gas chromatography-mass spectrometry analysis, which showed that the essential oils consisted of thirty-four compounds.  https://www.selleckchem.com/products/liraglutide.html  Chamazulene (39.21%), β-pinene (32.07%), and α-thujone (29.39%) were the main constituents of the essential oils of A. herba alba, A. absinthium and A. campestris, respectively.
