A low-toxicity method for the separation of lanosterol and dihydrolanosterol from commercial mixtures
We describe an inexpensive, low-toxicity and high-yielding method for the production of pure lanosterol and dihydrolanosterol from the commercially available mixture. Optimum conditions are presented for the one-pot production of the intermediate 24,25 vicinal diol of lanosterol acetate (via either epoxidation or hydroxyhalogenation) which is readily separated from the unreacted dihydrolanosterol acetate. The lanosterol diol can then be converted to pure (>97%) lanosterol. Hypophosphorous acid was used for both the conversion of the epoxide to the diol, and as a catalyst for the hydroxyhalogenation by N-halosuccinimides of the olefinic bond
Efficient routes to epimerically-pure side-chain derivatives of lanosterol
A technically simple route is described to individual epimers of side-chain derivatives of lanosterol (3-hydroxy-5-lanosta-8,24-diene). Epimerically pure 24,25-epoxy-, 24,25-dihydroxy- and 24-bromo-25-hydroxy-lanosterol have been prepared in good yield from commercial (50-60%) lanosterol. Hypophosphorous acid was used as a catalyst for the cohalogenation of the 24(25) bond and also for the efficient conversion of 24,25-epoxy- and 24-bromo-25-hydroxylanosterol to epimerically pure 24(R) or 24(S)-24,25-dihydroxylanosterols
Transforming the workforce through systems leadership and workplace facilitation of learning development and improvement
Developing standards for an integrated approach to workplace facilitation for interprofessional teams in health and social care contexts: a Delphi study
Integration of health and social care forms part of health and social care policy in many countries worldwide in response to changing health and social care needs. The World Health Organizationâs appeal for systems to manage the global epidemiologic transition advocates for provision of care that crosses boundaries between primary, community, hospital, and social care. However, the focus on structural and process changes has not yielded the full benefit of expected advances in care delivery.
Facilitating practice in the workplace is a widely recognised cornerstone for developments in the delivery of health and social care as collaborative and inclusive relationships enable frontline staff to develop effective workplace cultures that influence whether transformational change is achieved and maintained. Workplace facilitation embraces a number of different purposes which may not independently lead to better quality of care or improved patient outcomes. Holistic workplace facilitation of learning, development, and improvement supports the integration remit across health and social care systems and avoids duplication of effort and waste of valuable resources. To date, no standards to guide the quality and effectiveness of integrated facilitation have been published.
This study aimed to identify key elements constitute standards for an integrated approach to facilitating work-based learning, development, improvement, inquiry, knowledge translation, and innovation in health and social care contexts using a three rounds Delphi survey of facilitation experts from 10 countries. Consensus about priority elements was determined in the final round, following an iteration process that involved modifications to validate content. The findings helped to identify key qualities and skills facilitators need to support interprofessional teams to flourish and optimise performance.
Further research could evaluate the impact of skilled integrated facilitation on health and social care outcomes and the well-being of frontline interprofessional teams
Sorption of sulfamethoxazole, sulfachloropyridazine and sulfamethazine onto six New Zealand dairy farm soils
We have investigated the sorption potential of three sulfonamides (SAs) in six New Zealand dairy farming soils using a modified batch equilibrium method employing 0.005 M CaClâ as background solution. Both liquid and solid phases were extracted to analyse for the antibiotic concentrations in order to avoid underestimation that may arise a result of photolysis or biotic degradation. The experimental data were later used to construct Freundlich isotherms to determine the effective distribution coefficients. Low log Koc value for all SAs suggests considerable leaching potential for SAs under conditions that are conducive for leaching. The sorption affinity for all soils followed the trend SCP>SMZ>SMO
\u3ci\u3eCorynebacterium nebraskense\u3c/i\u3e, a New, Orange-Pigmented Phytopathogenic Species
A new species of Corynebacterium isolated from field corn is described. The isolates form a homogeneous group that is recognized as a new species, Corynebacterium nebraskense. The organism is characterized by orange-pig-mented colonies, inability to grow on 0.005% triphenyltetrazolium chloride agar, specific bacteriophage sensitivity, and a guanine plus cytosine content of 73.5 mol%. These and other characters differentiate this organism from other described phytopathogenic corynebacteria. The type strain of C. nebraskense is Fur-1 (= ATCC 27822 = NCPPB 2578)
Advancing the practice development outcomes agenda within multiple contexts
To-date the major focus and activity has been on clarifying the nature of practice development intervention and in developing and identifying approaches, methods and processes that fit with the intent of practice development work. Further effort has emphasised the importance of achieving this intent while ensuring that practice development work, as a 'complex intervention', is adapted locally and contextually. Whilst a range of outcomes have been achieved from systematic practice development work, the need to develop strategic level evaluation frameworks that reflect the complex and multi-faceted nature of practice development interventions has also been identified. The evolution of practice development as an effective intervention for enhancing practice and workplace cultures is contingent on the explication and demonstration of both the process and health outcomes it achieves. The accumulation of this evidence of effectiveness is required to ensure the uptake of practice development by policy makers and commissioners of quality and research enhancements across both health and academic sectors

Abstract
Safety in health care is an international concern with impact on quality of care (Hollnagel, et al, 2015). A Regional Patient Safety Collaborative (PSC), one of 15 nationally set up to place patients, carers and staff at the heart of quality improvements in patient safety, supported four large acute NHS hospital trusts with a PSC model to help facilitators use safety and quality improvement tools with frontline teams and to be mutually supported through action learning. The evaluation used realistic evaluation (Pawson & Tilley, 2004) (and the study and its findings are reported using the RAMESES 11 international standards (Wong et al, 2017). The study took place between June 2016-October 2017. Its aim was to understand what works for whom 3S.40-5.10pm1 Symposia- â Tuesday 17 April 2018 and why, when: working with frontline teams in large acute hospitals to embed a safety culture, and grow leadership and quality improvement capability. Specifically, to identify which strategies are effective in supporting front line teams to sustain bottom up change and quality improvement driven by the needs of patients and practitioners.
The study drew on ethnographic principlesacross study sites usingdescriptive case study design. Mixed methods of critical observation of frontline practice, stakeholder evaluation,emotional touch points, self-assessment;qualitative 360 degree feedback; and the Texas safety culture survey tool were used to facilitate the development of a rich picture for each teamand each context so as to answer the evaluation questions. In tandem, interrogation of the literature to distilled relationships between context, mechanisms and outcomes generating hypotheses at individual, team and organisational level factors for safety culture.
Key findings identified an interdependence between clinical leadership within frontline teams, safety culture, safety behaviours and teamwork echoed in microcosm through safety huddles; the skills and attributes of facilitators;and the impact of organisations on microsystems. Theories of culture change at the microsystems level are further embellished.

Abstract
This paper shares insights into the impact of system wide leadership initiatives that develop the facilitation capacity of the workforce to be effective clinical leaders in a time of increasingly complex system wide change (Manley et al, 2016, Crisp & Wilson 2011). The aim of this Delphi study (2015-16), was to develop a set of standards that could be used to guide an integrated approach to facilitation in and about the workplace. This includes the key qualities and skills required of facilitators who aim to integrate learning, development, improvement, inquiry, knowledge translation and innovation in and about the workplace. The study influenced by the knowledge base underpinning practice development methodology engaged international facilitation expertise. Three e-Delphi rounds involved participants from ten countries with expertise in facilitating either one or more of the purposes in work and/or about the workplace. The result, a set of standards builds on the current knowledge base about facilitation. The standards clarify the key components that facilitators need to attend to when supporting individuals, teams, organisations and services to achieve higher order learning in and about the workplace and positively impact on person centred cultures and health outcomes. The contribution of practice development as a discipline that integrates all the agendas was highlighted and needs to be promoted more explicitly at the policy level.
The key messages from this work are that: Facilitators work within different contexts and help staff appreciate the broader contexts in which they work. These contexts impact on both facilitator and staff purposes within and across each context. An integrated approach to facilitation aims to support a number of purposes. Enablers, skills and strategies for achieving these purposes are identified in the set of standards developed Facilitators need to attend to the evaluation of outcome and impact in the given context whilst keeping focus on constantly refining the processes that are effective.

Abstract
Definitions for continuous Professional Development (CPD) tend to focus on individual objectives, yet the goals of CPD activity are mutually interdependent on individual and system aspects (Billet, 2002) This paper presents the theoretical and practical insights gathered from a realist synthesis and evaluation (2014-2015) that led to a tool designed to measure the impact of learning on individual, team and organisational effectiveness in relation to improvements in quality of care and patient outcomes in the workplace. The aim of the project was to develop and test a CPD Impact Tool that identifies mechanisms for measuring the impact of learning on individual, team and organisational effectiveness and the indicators useful for providing information on individual and team effectiveness in relation to outcomes in the workplace? The study used mixed methods across two phases with different stakeholder groups to first develop theories about the relationship between contexts, mechanisms and outcomes for CPD to help understand which strategies work best for whom in what circumstance and why?
Phase 1 methods included: a literature review, underpinned by 12 critical questions, to identify what is known about CPD across three broad themes 1) What is CPD is and why it is important? 2) Purpose and impact of CPD, and 3) Facilitating and Judging the Effectiveness of CPD. This together with a stakeholder surveyanalysis and documentary analysis of CPDlearning outputs informed the development of the CPD framework and indicators which was then further tested in phase 2 with CPD providers, learner and an expert international reference group.
Key findings centre on four transformation theories that underpin an overarching framework for understanding effective CPD and a set of Impact indicators for guiding evaluation In order for CPD to be effective it has to address all of the interdependent outcomes for individual, team, service and organisational transformation.

Abstract
This paper presents a synthesis of the theoretical insights emerging from the three research studies together with outputs from a workshop for an international network of fellows. This synthesis is presented as a theoretical framework â the Venus Model for sustainable person centered transformation. This framework describes the key elements and linked concepts (and relationships) required to support front line teams (micro-systems) transform practice through interprofessional learning, development, improvement and innovation, and the essential organisational and systems factors required to enable this.
The five key elements of the model are 1) supporting development of facilitation skills across a continuum of complex purposes, 2) leadership development at clinical to systems levels, 3) practice development - a complex methodology that focuses on collaborative, inclusive and participative approaches with stakeholders,to develop person-centred, safe and effective cultures, 4) using quality improvement skills and tools, and 5) the culture change skills at the front line of practice. Bottom up, as opposed to top down models for supporting complex change in organisations are crucial to understand how to transform systems, services and cultures of care within and across organisations to deliver new models for 21st century health and well-being.
The symposium will conclude by sharing implications for practice based research and inquiry, workforce development and new emergent roles by considering how best to support and evidence the contribution of nurses to the future workforce on a global platform. This will include consideration of how nurses can take a leadership roles in both the delivery and evaluation of sustainable transformation across the health economy to impact on future new models of care
