Mentoring as a complex adaptive system - a systematic scoping review of prevailing mentoring theories in medical education.

BACKGROUND: Effective mentorship is an important component of medical education with benefits to all stakeholders. In recent years, conceptualization of mentorship has gone beyond the traditional dyadic experienced mentor-novice mentee relationship to include group and peer mentoring. Existing theories of mentorship do not recognize mentoring's personalized, evolving, goal-driven, and context-specific nature. Evidencing the limitations of traditional cause-and-effect concepts, the purpose of this review was to systematically search the literature to determine if mentoring can be viewed as a complex adaptive system (CAS). METHODS: A systematic scoping review using Krishna's Systematic Evidence-Based Approach was employed to study medical student and resident accounts of mentoring and CAS in general internal medicine and related subspecialties in articles published between 1 January 2000 and 31 December 2023 in PubMed, Embase, PsycINFO, ERIC, Google Scholar, and Scopus databases. The included articles underwent thematic and content analysis, with the themes identified and combined to create domains, which framed the discussion. RESULTS: Of 5,704 abstracts reviewed, 134 full-text articles were evaluated, and 216 articles were included. The domains described how mentoring relationships and mentoring approaches embody characteristics of CAS and that mentorship often behaves as a community of practice (CoP). Mentoring's CAS-like features are displayed through CoPs, with distinct boundaries, a spiral mentoring trajectory, and longitudinal mentoring support and assessment processes. CONCLUSION: Recognizing mentorship as a CAS demands the rethinking of the design, support, assessment, and oversight of mentorship and the role of mentors. Further study is required to better assess the mentoring process and to provide optimal training and support to mentors.

Poor Performance of Non-invasive Tests for Advanced Fibrosis in Nonalcoholic Fatty Liver Disease: A Multicentric Asian Study.

BACKGROUND: Non-invasive tests (NITs) are useful to assess advanced fibrosis (AF) in nonalcoholic fatty liver disease (NAFLD). Data from Asian countries suggest that these tests have poor performance. We aimed to assess diagnostic accuracy of established thresholds of biomarker-based NITs and Transient Elastography (TE) in identifying AF and evaluated the utility of a two-step test approach. METHODS: Biopsy-proven 641 NAFLD patients (55.2% males, median age 42 years) were included from three different centers of Asia. AF (≥ F3) was identified as per histological staging (24.8%). RESULTS: TE had the highest area under the receiver operating characteristic curve (AUROC) 0.82 (0.79-0.86), and all other biomarker-based NITs had low AUROC (< 0.7). NITs performed poorly at established thresholds. The combination of NITs utilizing liver stiffness measurement (LSM) and biomarkers, Agile 3+ and FAST, demonstrated acceptable diagnostic accuracy (AUROC 0.82 and 0.78, respectively), but none were superior to LSM alone. LSM measured using appropriate M and XL probes remained accurate regardless of body mass index (BMI); NFS and APRI scores were less accurate at higher BMI ranges. A two-step approach using NFS rule-out criteria (< - 2.97 to rule out) followed by LSM (< 7.3 kPa to rule out and ≥ 12.7 kPa to rule in) correctly classified 62.4% of patients, with only 10.2% of patients incorrectly classified. CONCLUSION: NITs have not been validated to identify AF in the Asian NAFLD population, and internationally accepted thresholds yield high false-negative rates. LSM and LSM-based combination tests remain the most accurate.

The total alkaloids of Sophora alopecuroides L. improve depression-like behavior in mice via BDNF-mediated AKT/mTOR signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Depression has become a global public health problem and the development of new highly effective, low-toxicity antidepressants is imminent. Sophora alopecuroides L. is a common medicinal plant, which has therapeutic effect on central nervous system diseases. AIM OF THE STUDY: In this study, the antidepressant effect of total alkaloids (ALK) isolated from Sophora alopecuroides L. was explored and the mechanism was further elucidated. MATERIALS AND METHODS: A primary neuronal injury model was established in vitro by corticosterone. ICR mice were then selected to construct an in vivo model of chronic unpredictable mild stress (CUMS)-induced depression, and the ameliorative effects of ALK on depression were examined by various behavioral tests. The antidepressant molecular mechanism of ALK was subsequently revealed by ELISA, Western blot, immunohistochemistry and Golgi staining. RESULTS: BDNF secretion as well as TrkB and ERK phosphorylated protein levels were found to be improved in primary cortical neurons, along with improved dendritic complexity of neurons. The results of in vivo showed that the depression-like behavior of CUMS-induced mice was reversed after 2 weeks of continuous gavage administration of ALK, and the neurotransmitter levels in the plasma of mice were increased. Moreover, the expression levels of key proteins of BDNF-AKT-mTOR pathway and the complexity of neuronal dendrites were improved in the prefrontal cortex of mice. CONCLUSIONS: These findings indicate that ALK of Sophora alopecuroides L. can effectively improve the depressive phenotype of mice, possibly by promoting the expression of BDNF in prefrontal cortex, activating the downstream AKT/mTOR signal pathway, and ultimately enhancing neuronal dendritic complexity.

A framework for mentoring of medical students: thematic analysis of mentoring programmes between 2000 and 2015.

A consistent mentoring approach is key to unlocking the full benefits of mentoring, ensuring effective oversight of mentoring relationships and preventing abuse of mentoring. Yet consistency in mentoring between senior clinicians and medical students (novice mentoring) which dominate mentoring processes in medical schools is difficult to achieve particularly when mentors practice in both undergraduate and postgraduate medical schools. To facilitate a consistent approach to mentoring this review scrutinizes common aspects of mentoring in undergraduate and postgraduate medical schools to forward a framework for novice mentoring in medical schools. Four authors preformed independent literature searches of novice mentoring guidelines and programmes in undergraduate and postgraduate medical schools using ERIC, PubMed, CINAHL, OVID and Science Direct databases. 25,605 abstracts were retrieved, 162 full-text articles were reviewed and 34 articles were included. The 4 themes were identified-preparation, initiating and supporting the mentoring process and the obstacles to effective mentoring. These themes highlight 2 key elements of an effective mentoring framework-flexibility and structure. Flexibility refers to meeting the individual and changing needs of mentees. Structure concerns ensuring consistency to the mentoring process and compliance with prevailing codes of conduct and standards of practice.

Mentoring relationships between senior physicians and junior doctors and/or medical students: A thematic review.

INTRODUCTION: Mentoring relationships are pivotal to the outcome of the mentoring process. This thematic review seeks to study the key aspects of mentoring relationships between senior physicians and junior doctors and/or medical students to inform efforts to improve mentoring programs. METHODS: Literature search was performed on publications across PubMed, ERIC, Cochrane Database of Systematic Reviews, OVID and ScienceDirect databases between 1 January 2000 and 31 December 2015 by three independent reviewers. The BEME guide and STORIES statement were used to develop a narrative from the articles selected. RESULTS: Thematic analysis of 49 articles reveals five semantic themes of initiation process, developmental process, evaluation process, sustaining mentoring relationship, and obstacles to effective mentoring. The evolving and relational-dependent nature of mentoring pivots upon the compatibility of mentors and mentees and the quality of their interactions, which in turn depend on mentoring environments and awareness of mentor-, mentee-, organizational-related factors and changes in context and goals. CONCLUSIONS: Embrace of a consistent mentoring approach to ensure effective oversight of the mentoring process must be balanced with sufficient flexibility to ensure a mentee-centered approach. Efforts must be made to optimize the key aspects of mentoring relationships in order to ensure successful mentoring processes and outcomes.
