RESUMEN

BACKGROUND: Mentoring relationships, for all medical school faculty members, are an important component of lifelong development and education, yet an understanding of mentoring among medical school clinical faculty members is incomplete. This study examined associations between formal mentoring relationships and aspects of faculty members' engagement and satisfaction. It then explored the variability of these associations across subgroups of clinical faculty members to understand the status of mentoring and outcomes of mentoring relationships. The authors hypothesised that academic clinical faculty members currently in formal mentoring relationships experience enhanced employee engagement and satisfaction with their department and institution. METHODS: Medical school faculty members at 26 self-selected USA institutions participated in the 2011-2014 Faculty Forward Engagement Survey. Responses from clinical faculty members were analysed for relationships between mentoring status and perceptions of engagement by faculty members. RESULTS: Of the 11 953 clinical faculty respondents, almost one-third reported having a formal mentoring relationship (30%; 3529). Most mentored faculty indicated the relationship was important (86%; n = 3027), and over three-fourths were satisfied with their mentoring experience (77%; n = 2722). Mentored faculty members across ranks reported significantly higher levels of satisfaction and more positive perceptions of their roles in the organisation. Faculty members who were not receiving mentoring reported significantly less satisfaction with their workplace environment and lower overall satisfaction. CONCLUSIONS: Mentored clinical faculty members have significantly greater satisfaction with their department and institution. This multi-institutional study provides evidence that fostering mentoring opportunities may facilitate faculty members' satisfaction and engagement, which, in turn, may help medical schools retain high-quality faculty staff committed to the multidimensional academic mission.

RESUMEN

Transcripts encoding a novel member of the lipoprotein receptor superfamily, termed LDL receptor-related protein (Lrp)13, were sequenced from striped bass (Morone saxatilis) and white perch (Morone americana) ovaries. Receptor proteins were purified from perch ovary membranes by protein-affinity chromatography employing an immobilized mixture of vitellogenins Aa and Ab. RT-PCR revealed lrp13 to be predominantly expressed in striped bass ovary, and in situ hybridization detected lrp13 transcripts in the ooplasm of early secondary growth oocytes. Quantitative RT-PCR confirmed peak lrp13 expression in the ovary during early secondary growth. Quantitative mass spectrometry revealed peak Lrp13 protein levels in striped bass ovary during late-vitellogenesis, and immunohistochemistry localized Lrp13 to the oolemma and zona radiata of vitellogenic oocytes. Previously unreported orthologs of lrp13 were identified in genome sequences of fishes, chicken (Gallus gallus), mouse (Mus musculus), and dog (Canis lupus familiaris). Zebrafish (Danio rerio) and Nile tilapia (Oreochromis niloticus) lrp13 loci are discrete and share genomic synteny. The Lrp13 appears to function as a vitellogenin receptor and may be an important mediator of yolk formation in fishes and other oviparous vertebrates. The presence of lrp13 orthologs in mammals suggests that this lipoprotein receptor is widely distributed among vertebrates, where it may generally play a role in lipoprotein metabolism.

RESUMEN

We evaluated changes in the striped bass (Morone saxatilis) ovary proteome during the annual reproductive cycle using label-free quantitative mass spectrometry and a novel machine learning analysis based on K-means clustering and support vector machines. Modulated modularity clustering was used to group co-variable proteins into expression modules and Gene Ontology (GO) biological process and KEGG pathway enrichment analyses were conducted for proteins within those modules. We discovered that components of the ribosome along with translation initiation and elongation factors generally decrease as the annual ovarian cycle progresses toward ovulation, concomitant with a slight increase in components of the 26S-proteasome. Co-variation within more than one expression module of components from these two multi-protein complexes suggests that they are not only co-regulated, but that co-regulation occurs through more than one sub-network. These components also co-vary with subunits of the TCP-1 chaperonin system and enzymes of intermediary metabolic pathways, suggesting that protein folding and cellular bioenergetic state play important roles in protein synthesis and degradation. We provide further evidence to suggest that protein synthesis and degradation are intimately linked, and our results support function of a proteasome-ribosome supercomplex known as the translasome.

RESUMEN

The Oklahoma Center for Mentoring Excellence (OCME) initiated faculty workshops to enhance their mentoring skills and establish an intercampus network for faculty specializing in clinical and biomedical sciences. The initial importance of mentoring competencies based on early career faculty members' perception and experience had not yet been determined. The Mentoring Competency Assessment validated by Fleming et al. (2013b) was used to rate the perceived importance of competencies and assess senior faculty members' competencies using a seven-point range, Likert-type response scale. Responses were analyzed by presence or absence of a mentor, previous formal mentor training, sex, and health science discipline. Junior faculty (n = 144) rated each competency as important or greater across all categories. A majority (70%) reported not having a current mentor. Junior faculty with current mentors rated senior faculty competencies higher than junior faculty without; participation in formal mentor training as well as a clinical faculty appointment were independently associated with higher assessment scores. This study identifies specific population characteristics that may serve to enhance the effectiveness of OCME workshops and demonstrates that junior faculty identify mentoring as significantly important in their academic career success in a research and clinical health setting.

RESUMEN

Introduction: Increasing faculty and leader diversity has been recommended as a way for health care organizations to achieve cultural competence in their patient care mission. Given the low numbers of underrepresented groups in medical school leadership positions, teaching diverse students and trainees the concept of leadership as influence may empower them to become more involved and bring diverse perspectives to their organizations. Methods: This 70-minute workshop consisted of a short presentation, a self-assessment, small- and large-group discussions, and case studies to: (1) describe the importance of diversity in medical school leadership, (2) define leadership, (3) define self-leadership, and (4) assess one's own self-leadership skills. The workshop was implemented at three US medical schools to diverse medical students and residents between September and December of 2019. Pre- and postworkshop evaluations were analyzed. Results: Greater than 95% of learners (n = 66) agreed that the workshop's learning objectives were met. Comments suggested participants appreciated learning about the lack of diversity among medical school leaders and the importance of cultivating their role in diversity in academic medicine. The case studies were highly rated and considered effective tools for learning. Discussion: This submission defined an empowering notion of leadership as influence. It taught learners that we can all lead (by influence) if we can improve our own self-leadership skills and become involved and bring diverse perspectives to health care organizations. Future research may focus on longer-term follow-up of participants to reassess their self-leadership skills and describe their level of involvement in their organizations.

RESUMEN

Introduction: Transitioning from trainee to practicing physician is a process that is not frequently discussed during postgraduate training, but such a discussion is necessary if the number of academic physicians is to increase and physicians from underrepresented communities are to gain insight about the varied opportunities to join academe. This workshop combines a case-based format in its didactic portion with a step-by-step guide and time line to introduce the process for securing an academic position postresidency. Methods: Kern's six-step model was used as the framework for the workshop's design, delivery, and assessment. The workshop was presented to medical students and residents at a series of programs fostering the development of the next generation of academic physicians that were offered at host medical schools across the US between July 2016 and May 2017. Results: Evaluation data were collected from 64 participants from nine academic medicine conferences across the nation. In comparing pre- and postworkshop responses, there was a statistically significant increase in confidence to find an academic position after residency (1.95 vs. 3.18, paired-sample t test, p < .001). More than 90% of respondents agreed or strongly agreed that the workshop's three objectives were met. Participants commented that they appreciated discussions on contracts and the steps they should take following residency in order to successfully obtain an academic position. Discussion: This workshop may assist trainees in making better-informed decisions about considerations that are important for finding and retaining an academic position long-term.

RESUMEN

Increasing rates of burnout-with accompanying stress and lack of engagement-among faculty, residents, students, and practicing physicians have caused alarm in academic medicine. Central to the debate among academic medicine's stakeholders are oft-competing issues of social accountability; cost containment; effectiveness of academic medicine's institutions; faculty recruitment, retention, and satisfaction; increasing expectations for faculty; and mission-based productivity.The authors propose that understanding and fostering what contributes to faculty and institutional vitality is central to preventing burnout during times of change. They first look at faculty vitality and how it is threatened by burnout, to provide a framework for a greater understanding of faculty well-being. Then they draw on higher education literature to determine how vitality is defined in academic settings and what factors affect faculty vitality within the context of academic medicine. Next, they propose a model to explain and examine faculty vitality in academic medicine, followed by a discussion of the need for a greater understanding of faculty vitality. Finally, the authors offer conclusions and propose future directions to promote faculty vitality.The authors encourage institutional decision makers and other stakeholders to focus particular attention on the evolving expectations for faculty, the risk of extensive faculty burnout, and the opportunity to reduce burnout by improving the vitality and resilience of these talented and crucial contributors. Faculty vitality, as defined by the institution, has a critical role in ensuring future institutional successes and the capacity for faculty to thrive in a complex health care economy.

RESUMEN

Assigning attributes to a birth cohort is one way we identify society-wide, shared life experiences within a group collectively called a "generation." Such assigned attributes influence society's adoption of generation-based expectations held by and about people from a particular birth cohort. Census data and generational attributes inform perspectives on millennial generation birth cohort experiences and engagement as students. The eldest living generation in U.S. society has given way to 3 subsequent generations, the youngest of which is called the millennial generation. What generational attributes influence the effectiveness of teaching and learning between millennial learners and faculty members from other generations? Understanding the role of life cycle effects, period effects and cohort effects can offer medical and health professions educators' insights into different strategies for learner engagement. Discussion includes specific strategies and teaching tactics faculty members can use to engage millennials across a continuum of learning to bridge the "expectation gap."

RESUMEN

We quantified three vitellogenins (VtgAa, VtgAb, VtgC) or their derived yolk proteins (YPs) in the liver, plasma, and ovary during pre-vitellogenic (PreVG), mid-vitellogenic (MVG), and late-vitellogenic (LVG) oocyte growth and during post-vitellogenesis (PostVG) in the striped bass (Morone saxatilis) using label-free quantitative mass spectrometry (MS). Western blotting of the samples using antisera raised against gray mullet (Mugil cephalus) lipovitellins derived from VtgAa, VtgAb, and VtgC confirmed the MS results. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) revealed liver as the primary site of expression for all three Vtgs, with extra-hepatic transcription weakly detected in ovary, foregut, adipose tissue, and brain. Quantitative real-time RT-PCR confirmed vtgAb to be primarily expressed in liver and VtgAb proteins were predominant in liver and plasma from MVG to PostVG. However, the primary period of deposition into oocytes of VtgAb occurred up until MVG, whereas VtgAa was primarily deposited from MVG to LVG. The VtgC was gradually taken up by oocytes throughout vitellogenesis and was detected at trace levels in plasma. The ratio of yolk proteins derived from VtgAa, VtgAb, VtgC (YPAa/YPAb/YPC) in PostVG ovary is 1.4:1.4:1, which differs from ratios previously reported for other fish species in that YPC comprises a greater proportion of the egg yolk. Our results indicate that proportional accumulation of multiple Vtgs in the yolk may depend both on the precise rates of their hepatic secretion and specific uptake by oocytes. Furthermore, composition of the Vtg-derived yolk may vary among Acanthomorph fishes, perhaps reflecting their different early life histories and reproductive strategies.

RESUMEN

PURPOSE: To examine the current state of satisfaction with the academic medicine workplace among U.S. medical school faculty and the workplace factors that have the greatest influence on global satisfaction. METHOD: The authors used data from the 2009 administration of a medical school faculty job satisfaction survey and used descriptive statistics and χ analyses to assess levels of overall satisfaction within faculty subgroups. Multiple regressions used the mean scores of the 18 survey dimensions and demographic variables to predict three global satisfaction measures. RESULTS: The survey was completed by 9,638 full-time faculty from 23 U.S. medical schools. Respondents were mostly satisfied on global satisfaction measures including satisfaction with their department (6,506/9,128; 71.3%) and medical school (5,796/9,124; 63.5%) and whether they would again choose to work at their medical school (5,968/8,506; 70.2%). The survey dimensions predicted global satisfaction well, with the final models explaining 51% to 67% of the variance in the dependent measures. Predictors across models include organization, governance, and transparency; focus of mission; recruitment and retention effectiveness; department relationships; workplace culture; and nature of work. CONCLUSIONS: Despite the relatively unpredictable environmental challenges facing medical schools today, leaders have opportunities to influence and improve the workplace satisfaction of their faculty. Examples of opportunities include fostering a culture characterized by open communication and occasions for faculty input, and remaining vigilant regarding factors contributing to faculty burnout. Understanding what drives faculty satisfaction is crucial for medical schools as they continue to seek excellence in all missions and recruit and retain high-quality faculty.

RESUMEN

An aquaculture research facility experienced high mortality rates in white bass Morone chrysops associated with a monogenean infestation of the gills, but not in striped bass Morone saxatilis in the same facility. All mortalities had pale gills. Monogeneans, identified as Gamacallum macroura (MacCallum and MacCallum 1913) Unnithan 1971, were found on the gills. Pale-gilled and healthy white bass were selected with no particular attention to condition for venipuncture and euthanasia for postmortem examination, including parasite counts from gills. The median packed cell volume (PCV) of fish with gill pallor was 12.5% (range 9-37%) while PVC of fish with more normal color was 30% (27-33%). Association between the PCV and gill pallor score was statistically significant, as was the association between PCV and the number of monogeneans found on the gills of each fish. Median estimated white blood cell count of fish with gill pallor, at 12.05 × 10(3/)µL (range 3.8-24.7), was significantly lower than of apparently healthy fish: 24.7 × 10(3)/µL (17.3-31.5). Histopathology of the gill arches of pale-gilled fish revealed multifocal moderate to severe branchitis, focal areas of dilated hyperplastic lamellae occluded by fibrin, and monogeneans attached to the lamellae. Fish that were apparently healthy had grossly similar histologic lesions, but at lower frequency and severity.
