RESUMEN

BACKGROUND: Arts-and-humanities-based interventions are commonly implemented in medical education to promote well-being and mitigate the risk of burnout. However, mechanisms for achieving these effects remain uncertain within graduate medical education. The emerging field of the positive humanities offers a lens to examine whether and how arts-based interventions support well-being in internal medicine interns. AIM: Through program evaluation of this visual art workshop, we used a positive humanities framework to elucidate potential mechanisms by which arts-based curricula support well-being in internal medicine interns. SETTING: We launched the re-FRAME workshop at the Philadelphia Museum of Art in winter 2020. PARTICIPANTS: Fifty-six PGY-1 trainees from one internal medicine residency program. PROGRAM DESCRIPTION: The 3-h re-FRAME workshop consisted of an introductory session on emotional processing followed by two previously described arts-based interventions. PROGRAM EVALUATION: Participants completed an immediate post-workshop survey (91% response rate) assessing attitudes towards the session. Analysis of open-ended survey data demonstrated 4 categories for supporting well-being among participants: becoming emotionally aware/expressive through art, pausing for reflection, practicing nonjudgmental observation, and normalizing experiences through socialization. DISCUSSION: Our project substantiated proposed mechanisms from the positive humanities for supporting well-being-including reflectiveness, skill acquisition, socialization, and expressiveness-among medical interns.

RESUMEN

OBJECTIVE: Two-thirds of United States medical boards require disclosure of mental health treatment or diagnosis during licensure, with negative influence on physician well-being but unknown impact on medical students. This study sought to understand whether medical students perceive mental health treatment to be a threat to their future medical license. METHOD: Students at an American medical school in a state without disclosure questions completed an anonymous fourteen question survey. Analysis with univariate and multivariate statistics explored knowledge, opinion, and impact of disclosure questions. RESULTS: Data was obtained from 327 medical students, a 53% response rate. The majority-91% (299)-were unsure or incorrect as to whether their state licensing board requires mental health disclosure. 33% (86) reported disclosure questions substantially discourage them from seeking mental health treatment. Of the 32% (105) who accessed mental health treatment during medical school, half-52% (74)-would not disclose during licensing. Those who believe that disclosure could impact their license were more likely to be discouraged from seeking care (OR, 5.23 [95% CI, 1.97-15.99]; P = 0.002). Most students-75% (245)-opposed mandatory disclosure. CONCLUSIONS: Concern about mandatory mental health disclosure discourages medical students from seeking care, despite uncertainty about disclosure questions.

RESUMEN

Introduction: Burnout in medical students is extensive and a critical issue. It is associated with increased rates of depression, suicide, and poor perception of the educational environment. Enhancing resilience, the ability to adapt well in the face of adversity, is a potential tool to mitigate burnout and improve medical student wellness. Methods: Our resilience curriculum consisted of facilitated workshops to cultivate resilience in medical students during their core clerkship rotations. This curriculum served as an introduction to the concept of resilience and taught skills to cultivate resilience and promote wellness. The sessions allowed for identification of and reflection on stressors in the clinical learning environment, including straining team dynamics, disappointment, and uncertainty. Educational sessions included resilience skill-building exercises for managing expectations, letting go of negative emotions, dealing with setbacks, and finding meaning in daily work. Associated materials included lesson plans for small-group facilitators, learner pre- and postcurriculum surveys, and a social media activity guide. Results: This curriculum was delivered to 144 clerkship students at two academic institutions over the 2017-2018 academic year. Sessions were well received by medical students, with the majority of students stating that the sessions should continue. The majority of attendees found the sessions valuable and learned new ways to approach challenges. Discussion: Students valued connecting with peers and feeling less alone through their participation. A challenge was constructing a setting conducive to comfortable reflection for all learners. Not all students found these sessions necessary. Sessions may have improved resilience levels.

RESUMEN

BACKGROUND: Technological improvements have shifted the focus from data generation to data analysis. The availability of large amounts of data from transcriptomics, protemics and metabolomics experiments raise new questions concerning suitable integrative analysis methods. We compare three integrative analysis techniques (co-inertia analysis, generalized singular value decomposition and integrative biclustering) by applying them to gene and protein abundance data from the six life cycle stages of Plasmodium falciparum. Co-inertia analysis is an analysis method used to visualize and explore gene and protein data. The generalized singular value decomposition has shown its potential in the analysis of two transcriptome data sets. Integrative Biclustering applies biclustering to gene and protein data. RESULTS: Using CIA, we visualize the six life cycle stages of Plasmodium falciparum, as well as GO terms in a 2D plane and interpret the spatial configuration. With GSVD, we decompose the transcriptomic and proteomic data sets into matrices with biologically meaningful interpretations and explore the processes captured by the data sets. IBC identifies groups of genes, proteins, GO Terms and life cycle stages of Plasmodium falciparum. We show method-specific results as well as a network view of the life cycle stages based on the results common to all three methods. Additionally, by combining the results of the three methods, we create a three-fold validated network of life cycle stage specific GO terms: Sporozoites are associated with transcription and transport; merozoites with entry into host cell as well as biosynthetic and metabolic processes; rings with oxidation-reduction processes; trophozoites with glycolysis and energy production; schizonts with antigenic variation and immune response; gametocyctes with DNA packaging and mitochondrial transport. Furthermore, the network connectivity underlines the separation of the intraerythrocytic cycle from the gametocyte and sporozoite stages. CONCLUSION: Using integrative analysis techniques, we can integrate knowledge from different levels and obtain a wider view of the system under study. The overlap between method-specific and common results is considerable, even if the basic mathematical assumptions are very different. The three-fold validated network of life cycle stage characteristics of Plasmodium falciparum could identify a large amount of the known associations from literature in only one study.

RESUMEN

Microparticles are cell-derived, membrane-sheathed structures that are believed to shuttle proteins, mRNA, and miRNA to specific local or remote target cells. To date best described in blood, we now show that cerebrospinal fluid (CSF) contains similar structures that can deliver RNAs and proteins to target cells. These are, in particular, molecules associated with neuronal RNA granules and miRNAs known to regulate neuronal processes. Small RNA molecules constituted 50% of the shuttled ribonucleic acid. Using microarray analysis, we identified 81 mature miRNA molecules in CSF microparticles. Microparticles from brain injured patients were more abundant than in non-injured subjects and contained distinct genetic information suggesting that they play a role in the adaptive response to injury. Notably, miR-9 and miR-451 were differentially packed into CSF microparticles derived from patients versus non-injured subjects. We confirmed the transfer of genetic material from CSF microparticles to adult neuronal stem cells in vitro and a subsequent microRNA-specific repression of distinct genes. This first indication of a regulated transport of functional genetic material in human CSF may facilitate the diagnosis and analysis of cerebral modulation in an otherwise inaccessible organ.

RESUMEN

In the pediatric cancer alveolar rhabdomyosarcoma (ARMS), the 2;13 chromosomal translocation juxtaposes the PAX3 and FKHR genes to generate a chimeric transcription factor. To explore molecular pathways altered by this oncoprotein, we generated an inducible form by fusing PAX3-FKHR to a modified estrogen receptor ligand-binding domain and expressed this construct in the RD embryonal rhabdomyosarcoma cell line. This inducible system permits short-term evaluation of downstream expression targets of PAX3-FKHR and complements a panel of stable long-term RD subclones constitutively expressing PAX3-FKHR. Using these two sets of resources, we investigated several candidate PAX3-FKHR target genes. First, we demonstrated in both short-term and long-term systems that PAX3-FKHR upregulates expression of the gene encoding the chemokine receptor CXCR4. In addition, we found that expression of wild-type PAX3 is upregulated, whereas expression of wild-type PAX7 is downregulated by PAX3-FKHR. In the presence of cycloheximide, CXCR4 and PAX3 are still inducible, supporting the hypothesis that these genes are direct transcriptional targets of PAX3-FKHR. Finally, studies of ARMS tumors revealed CXCR4, PAX3, and PAX7 expression levels consistent with our cell culture results. These findings of genes regulated by PAX3-FKHR will direct future biological and clinical investigation to important pathways contributing to ARMS tumorigenesis and progression.

RESUMEN

We hypothesized that the CXC chemokine receptor-4 (CXCR4)-stromal-derived factor-1 (SDF-1) axis may be involved in metastasis of CXCR4(+) tumor cells into the bone marrow and lymph nodes, which secrete the alpha-chemokine SDF-1. To explore this hypothesis, we phenotyped by fluorescence-activated cell sorter analysis various human tumor cell lines for expression of CXCR4 and found that it was highly expressed on several rhabdomyosarcoma (RMS) cell lines. We also observed that cell lines derived from alveolar RMS, which is characterized by recurrent PAX3- and PAX7-FKHR gene fusions and is associated with a poor prognosis, expressed higher levels of CXCR4 than lines derived from embryonal RMS. Furthermore, transfer of a PAX3-FKHR gene into embryonal RMS cell activates CXCR4 expression. Because alveolar RMS frequently metastasizes to the bone marrow and lymph nodes, it seems that the CXCR4-SDF-1 axis could play an important role in this process. These findings prompted us to determine whether SDF-1 regulates the metastatic behavior of RMS cells. Accordingly, we found that, although SDF-1 did not affect proliferation or survival of these cell lines, it induced in several of them (1) phosphorylation of mitogen-activated protein kinase p42/44; (2) locomotion; (3) directional chemotaxis across membranes covered by laminin, fibronectin, or Matrigel; (4) adhesion to laminin, fibronectin, and endothelial cells; and (5) increased MMP-2 and diminished tissue inhibitors of metalloproteinases secretion. The small-molecule CXCR4-specific inhibitor, T140, effectively blocked the in vitro responses of RMS cells to SDF-1. On the basis of these observations we suggest that the CXCR4-SDF-1 axis may play an important role in tumor spread and metastasis of RMS cells to bone marrow and that molecular strategies aimed at inhibiting this axis could thus prove to be useful therapeutic measures.

RESUMEN

PAX3 is a transcription factor important for neural, muscle, and facial development in vertebrates. To identify genes regulated by PAX3, we used a cyclic amplification and selection of targets (CASTing) strategy to isolate cis-regulatory elements bound by PAX3. CASTing libraries were constructed with mouse DNA fragments bound by mouse PAX3, and human genomic DNA fragments bound by human PAX3 and the fusion protein PAX3-FKHR. Approximately 1000 clones were sequenced from each of these three libraries. Numerous putative targets of PAX3 and PAX3-FKHR were identified and six genes, Itm2A, Fath, FLT1, TGFA, BVES, and EN2, were examined closely. The genomic DNA fragments near these genes contain PAX3 binding sites and confer PAX3-dependent regulation. The expression levels of these genes correlate with the PAX3 expression levels in mouse embryos or with PAX3-FKHR expression levels in rhabdomyosarcoma cell lines, and indicate they may be part of the PAX3 regulatory circuitry during embryogenesis and tumor formation.
