Twelve tips for implementing a community of practice for faculty development

Teaching and learning practices often fail to incorporate new concepts in the ever-evolving field of medical education. Although medical education research provides new insights into curricular development, learners' engagement, assessment methods, professional development, interprofessional education, and so forth, faculty members often struggle to modernize their teaching practices. Communities of practice (CoP) for faculty development offer an effective and sustainable approach for knowledge management and implementation of best practices. A successful CoP creates and shares knowledge in the context of a specific practice toward the development of expertise. CoPs' collaborative nature, based on the co-creation of practical solutions to daily problems, aligns well with the goals of applying best practices in health professions education and training new faculty members. In our article, we share 12 tips for implementing a community of practice for faculty development. The tips were based on a comprehensive literature review and the authors' experiences

Junior doctors' experiences with interprofessional collaboration:Wandering the landscape

Context The transition from medical student to junior doctor is challenging. Junior doctors need to become part of the physician community of practice (CoP), while dealing with new responsibilities, tasks and expectations. At the same time, they need to learn how to navigate the frontiers and intersections with the other communities of practice that form the Landscape of Practice (LoP). This study aims to understand how junior doctors experience interprofessional collaboration (IPC) and what elements shape these experiences considering their transition to clinical practice. Methods In this multicentre qualitative study, 13 junior doctors individually drew two rich pictures of IPC experiences, one positive and one negative. A rich picture is a visual representation, a drawing of a particular situation intended to capture the complex and non-verbal elements of an experience. We used semi-structured interviews to deepen the understanding of junior doctors' depicted IPC experiences. We analysed both visual materials and interview transcripts iteratively, for which we adopted an inductive constructivist thematic analysis. Results While transitioning into a doctor, junior doctors become foremost members of the physician CoP and shape their professional identity based on perceived values in their physician community. Interprofessional learning occurs implicitly, without input from the interprofessional team. As a result, junior doctors struggle to bridge the gap between themselves and the interprofessional team, preventing IPC learning from developing into an integrative process. This professional isolation leaves junior doctors wandering the landscape of practice without understanding roles, attitudes and expectations of others. Conclusions Learning IPC needs to become a collective endeavour and an explicit learning goal, based on multisource feedback to take advantage of the expertise already present in the LoP. Furthermore, junior doctors need a safe environment to embrace and reflect on the emotions aroused by interprofessional interactions, under the guidance of experienced facilitators

Learn+Fun! Social Media and Gamification sum up to foster a community of practice during an Emergency Medicine Rotation

Purpose: Medical students and clinical teachers thrive to establish meaningful learning relationships in overwhelmed and ever-shorter clinical rotations. The challenge for medical educators is to design pedagogical approaches capable of bonding students and teachers into the same community of practice (CoP). In this work, the authors explored how Social Media and Gamification strategies sum up to boost medical students’ participation in a blended learning strategy to teach Emergency Medicine. Method: Final year medical students (n = 462) from 5 consecutive years were included in a longitudinal study with historical controls and were divided into three groups. The first group (CONTROL; n = 125) had access to a blended learning strategy; the second group (FACE; n = 179) had access to the blended learning strategy and interacted with a fictional facilitator in Social Media; and the third group (GAME; n = 158) had access to the former strategies plus a gamification approach. Results: Social media and gamification progressively increased students’ participation in the online course as measured by the number of hours logged on from an average of 60 h in CONTROL to 87 h in FACE and 140 h in GAME (P < 0.01). There was a positive and significant correlation between students’ grades on cognitive tests and OSCEs exams with the online participation. Both strategies nurtured students’ sense of belonging to the community of Emergency Medicine and improved their self-regulation to study. Discussion: Social Media and Gamification catalyzed the consolidation of a shared identity for students and teachers, which fostered the creation of a community of practice and increased the participation of students in learning activities.

Insulin and angiotensin II signaling pathways cross-talk: implications with the association between diabetes mellitus, arterial hypertension and cardiovascular disease

Insulin (Ins) and angiotensin II (AII) play pivotal roles in the control of two vital and closely related systems: the metabolic and the circulatory, respectively. A failure in the proper action of each of these hormones results, to a variable degree, in the development of two highly prevalent and commonly overlapping diseases - diabetes mellitus (DM) and hypertension (AH). In recent years, a series of studies has revealed a tight connection between the signal transduction pathways that mediate Ins and AII actions in target tissues. This molecular cross-talk occurs at multiple levels and plays an important role in phenomena that range from the action of anti-hypertensive drugs to cardiac hypertrophy and energy acquisition by the heart. At the extracellular level, the angiotensin-converting enzyme controls AII synthesis but also interferes with Ins signaling through the proper regulation of AII and the accumulation of bradykinin. At an early intracellular level, AII, acting through JAK-2/IRS-1/PI3-kinase, JNK and ERK, may induce the serine phosphorylation and inhibition of key elements of the Ins-signaling pathway. Finally, by inducing the expression of the regulatory protein SOCS-3, AII may impose a late control on the Ins signal. This review will focus on the main advances obtained in this field and will discuss the implications of this molecular cross-talk in the common clinical association between DM and AH.Insulina (Ins) e Angiotensina II (AII) são fundamentais no controle de dois sistemas vitais e inter-relacionados: o metabólico e o cardiocirculatório, respectivamente. A disfunção de qualquer um desses hormônios pode levar ao desenvolvimento de duas doenças de alta prevalência, muitas vezes concomitantes e, talvez, com fisiopatologia integrada - diabetes mellitus (DM) e hipertensão arterial (HA). Vários estudos mostram que os sistemas de sinalização intracelular de Ins e AII estão conectados e influenciam um ao outro. Esta comunicação molecular ocorre em diferentes etapas da sinalização celular e é importante para vários fenômenos fisiológicos, desde o desenvolvimento de hipertrofia cardíaca e aquisição de energia pelo coração, até a ação de drogas anti-hipertensivas. No nível extracelular, a enzima de conversão de angiotensina regula a síntese de AII e o acúmulo de bradicinina, e ambos desempenham papel regulador sobre a sinalização de Ins. No nível intracelular, a interação dos sinais de Ins e AII ocorre em dois momentos distintos. Inicialmente, em etapas mais precoces da sinalização celular, a AII, atuando através da cascata JAK-2/IRS-1/PI3-quinase, JNK e ERK, provoca a fosforilação em serina e a conseqüente inibição de elementos-chave da via de sinalização da Ins. Finalmente, a AII induz a expressão da proteína regulatória SOCS-3, que impõe um controle mais tardio sobre o sinal de Ins. Esta revisão discute os avanços mais recentes neste campo e a importância dessa interação molecular na fisiopatologia e na associação clínica de DM e HA.19520

Anti-Black racism in clinical supervision:asynchronous simulated encounters facilitate reflective practice

Background: Racist interactions in clinical practice remain a pervasive reality for Black healthcare providers. We sought to develop a framework to inform supervisors' actions when confronting racism in clinical practice and protecting trainees under their oversight.Methods: We conducted a qualitative study in which experienced supervisors responded to seven short, videotaped interactions between: 1) Black trainees and a simulated patient (SP) in a racist role; 2) the trainees and their respective supervisors; and 3) the trainees and their supervisors together with the SP. The clinical exchanges exemplified different types of racist (entrenching) or antiracist (uprooting) behaviors by the supervisors. After viewing each clip, participants wrote their reflections confidentially; they later joined a structured debriefing together. We used thematic analysis to identify supervisors' behavioral patterns when confronting racist interactions.Results: Based on the input of 52 participants recruited into five two-hour-long sessions, we categorized the behaviors of supervisors facing anti-Black racial injuries involving learners under their oversight. We organized supervisor behaviors into five interlocking domains, each with a range of possible themes: 1) Joining: from conciliatory to confrontational in communicating with the aggressor; 2) Explicitness: from avoiding to naming racism; 3) Ownership: from individual to shared responsibility of the event and the response to it; 4) Involving: from excusing to including the aggrieved party when confronting the aggressor; and 5) Stance: from protective to paternalistic in supporting the learner's autonomy.Conclusions: Our qualitative findings can provide a framework for facilitated discussion toward reflective practice among healthcare providers who may have experienced, witnessed, or intervened in anti-Black racist interactions. They can also help medical educators to inform faculty development to fight anti-Black racism in clinical practice. The video materials we developed are available for viewing and download and can be used or adapted as springboards for reflective discussion or faculty development activities. </p

Handling Time and Bite Mass Mechanisms in Large Herbivores: Contrasts between Sward Structure and Grazing Methods

Grazing is a time-dependent process where jaw movements of prehension, handling and chewing compete with them (Laca et al. 1994; Ungar et al. 2006). The grazing efficiency is dependent of bite mass and time per bite. Bite mass has been related to sward structure by forage height, structural components (Cangiano et al. 2002). In rotational stocking this effect becomes more pronounced, especially under high grazing down levels. Consequently, there is a progressive reduction in short-term intake rate (Fonseca et al. in press). New management targets should be proposed based on the predominant influence of sward structure in short-term intake rate by grazing animals (Carvalho et al. 2007). We hypothesise that intake potential of animals grazing tropical pastures will be reduced due to higher constraints in bite formation when compared to temperate pastures. This study aimed to investigate the intake process of heifers under the influence of different sward heights and grazing down levels in two contrasting - tropical and temperate - forage species

Psychological distress among frontline workers during the COVID-19 pandemic:A mixed-methods study

BACKGROUND: Novel virus outbreaks, such as the COVID-19 pandemic, may increase psychological distress among frontline workers. Psychological distress may lead to reduced performance, reduced employability or even burnout. In the present study, we assessed experienced psychological distress during the COVID-19 pandemic from a self-determination theory perspective. METHODS: This mixed-methods study, with repeated measures, used surveys (quantitative data) combined with audio diaries (qualitative data) to assess work-related COVID-19 experiences, psychological need satisfaction and frustration, and psychological distress over time. Forty-six participants (nurses, junior doctors, and consultants) completed 259 surveys and shared 60 audio diaries. Surveys and audio diaries were analysed separately. RESULTS: Quantitative results indicated that perceived psychological distress during COVID-19 was higher than pre-COVID-19 and fluctuated over time. Need frustration, specifically autonomy and competence, was positively associated with psychological distress, while need satisfaction, especially relatedness, was negatively associated with psychological distress. In the qualitative, thematic analysis, we observed that especially organisational logistics (rostering, work-life balance, and internal communication) frustrated autonomy, and unfamiliarity with COVID-19 frustrated competence. Despite many need frustrating experiences, a strong connection with colleagues and patients were important sources of relatedness support (i.e. need satisfaction) that seemed to mitigate psychological distress. CONCLUSION: The COVID-19 pandemic resulted in an increase of psychological distress among frontline workers. Both need frustration and need satisfaction explained unique variance of psychological distress, but seemed to originate from different sources. Challenging times require healthcare organisations to better support their professionals by tailored formal and informal support. We propose to address both indirect (e.g. organisation) and direct (e.g. colleagues) elements of the clinical and social environment in order to reduce need frustration and enhance need satisfaction

Targeted disruption of inducible nitric oxide synthase protects against aging, S-nitrosation, and insulin resistance in muscle of male mice

Accumulating evidence has demonstrated that S-nitrosation of proteins plays a critical role in several human diseases. Here, we explored the role of inducible nitric oxide synthase (iNOS) in the S-nitrosation of proteins involved in the early steps of the insulin-signaling pathway and insulin resistance in the skeletal muscle of aged mice. Aging increased iNOS expression and S-nitrosation of major proteins involved in insulin signaling, thereby reducing insulin sensitivity in skeletal muscle. Conversely, aged iNOS-null mice were protected from S-nitrosation–induced insulin resistance. Moreover, pharmacological treatment with an iNOS inhibitor and acute exercise reduced iNOS-induced S-nitrosation and increased insulin sensitivity in the muscle of aged animals. These findings indicate that the insulin resistance observed in aged mice is mainly mediated through the S-nitrosation of the insulin-signaling pathway
