Examination of residency program websites for the use of gendered language and imagery.

BACKGROUND: Significant disparity in gender distribution exists among medical specialties. Residency program websites are a main source of preliminary program information for candidates, and website content may influence a prospective applicant's sense of belongingness within a particular program. Given the importance of the residency program website as a recruiting tool, this study sought to examine and compare the presence of gendered language and imagery on residency program websites across various specialties. METHODS: A list of words considered masculine or feminine was used to evaluate residency program websites of the two most male-dominated specialties (orthopedic and thoracic surgery), female-dominated specialties (pediatrics and obstetrics and gynecology), and gender-balanced specialties (dermatology and family medicine) in the United States in 2022. Forty-five residency programs were randomly selected from each specialty across different regions of the US, with the exception of thoracic surgery of which there are only 33 programs. Masculine and feminine words were evaluated using a parsing and scraping program. Representation of female and male-presenting team members in photos on program websites was also evaluated. RESULTS: Masculine wording occurred more frequently in male-dominated specialties compared to gender-balanced (p = 0.0030), but not female-dominated specialties (p = 0.2199). Feminine language was used more frequently in female-dominated compared to male dominated fields (p = 0.0022), but not gender balanced (p = 0.0909). The ratio of masculine-to-feminine words used was significantly higher in male-dominated specialties compared to both gender-balanced (p < 0.0001) and female-dominated specialties. (p < 0.0001). There was an average of 1, 7, and 10 female-presenting residency team members pictured on each male-dominated, gender balanced, and female-dominated specialty RPW respectively, with significantly more female-presenting team members pictured in the photographs on female-dominated specialty websites when compared to male-dominated and gender-balanced specialty websites (p < 0.0001, p = 0.014). CONCLUSIONS: The use of gendered language and female representation in photographs varies significantly across specialties and is directly correlated with gender representation within the specialty. Given that students' perceptions of specialty programs may be affected by the use of language and photos on residency program websites, programs should carefully consider the language and pictures depicted on their program websites.

The use of artificial intelligence to detect students' sentiments and emotions in gross anatomy reflections.

Students' reflective writings in gross anatomy provide a rich source of complex emotions experienced by learners. However, qualitative approaches to evaluating student writings are resource heavy and timely. To overcome this, natural language processing, a nascent field of artificial intelligence that uses computational techniques for the analysis and synthesis of text, was used to compare health professional students' reflections on the importance of various regions of the body to their own lives and those of the anatomical donor dissected. A total of 1365 anonymous writings (677 about a donor, 688 about self) were collected from 132 students. Binary and trinary sentiment analysis was performed, as well as emotion detection using the National Research Council Emotion Lexicon which classified text into eight emotions: anger, fear, sadness, disgust, surprise, anticipation, trust, and joy. The most commonly written about body regions were the hands, heart, and brain. The reflections had an overwhelming positive sentiment with major contributing words "love" and "loved." Predominant words such as "pain" contributed to the negative sentiments and reflected various ailments experienced by students and revealed through dissections of the donors. The top three emotions were trust, joy, and anticipation. Each body region evoked a unique combination of emotions. Similarities between student self-reflections and reflections about their donor were evident suggesting a shared view of humanization and person centeredness. Given the pervasiveness of reflections in anatomy, adopting a natural language processing approach to analysis could provide a rich source of new information related to students' previously undiscovered experiences and competencies.

Increased medical student understanding of dementia through virtual embodiment.

Given the growing prevalence of Alzheimer's disease (AD), we assessed the impact of virtually embodying someone with progressive AD. This pilot explored students' understanding of individuals' needs with dementia, as well as, the efficacy of virtual reality (VR) as a curricular tool. Second-year medical students (n = 150) completed a pre-survey, Embodied Labs, Inc. Beatriz Lab VR module, and a post-survey. Most students knew someone with dementia (72%), were a family member of someone with dementia (52%) or had worked with a patient (61%) with dementia. Using paired survey questions, students reported significant increases in understanding how their lives would be affected by dementia (71% vs. 94%) and the needs of a person with dementia (64% vs. 95%) after VR. They reported increased understanding of being a caregiver of someone with dementia (24% vs. 81%) and the impact it can have on the entire family (64% vs. 97%). Overall students agreed this simulation made them think about their approach to clinical skills (94%) and should be utilized more in the curriculum (76%). This pilot study indicated that this VR experience can be used to advance understanding of a person's experiences with dementia and that integrating VR into the medical curricula should be considered.

A Pilot Study of the Impact of Virtually Embodying a Patient with a Terminal Illness.

Compassionate end-of-life care matters deeply for patients and their caregivers, but studies continue to demonstrate ways in which physicians fall short. Despite specific training during medical school, many patients report lack of empathy in their providers with respect to end-of-life conversations. This is likely because empathy is simply hard to teach. Numerous activities have been tried to combat the decline in empathy during medical training with little to moderate success. However, virtual reality, which allows users to viscerally experience anything from another person's point of view, could be a game changer for building empathy within medicine. This type of perspective-taking has previously shown to improve understanding, reduce biases, facilitate empathy, and promote prosocial behaviors. In this pilot study, virtual reality was used to allow students to "become a patient" virtually embodying their daily activities, symptoms, and interactions with caregivers. Using the Embodied Labs modules, first-year medical students were able to experience first-hand having a terminal illness, being told no further treatments are available and witnessing loved ones' reactions. Data generated through surveys and reflections indicated a high level of place illusion, plausibility, and embodiment of users. This high level of immersion generated an increase in comfortability with talking about end-of-life issues, produced a better understanding of what patients and their families experience, and promoted a change in the way students would approach clinical skills. Analysis of reflections indicated a high level of empathy for the patient and his family members. Overall, the activity was highly received by students as a valuable learning activity. As such, we propose that virtual reality could be a useful pedagogical tool to facilitate empathy and clinical skills within medical education.

Virtually Walking in a Patient's Shoes-the Path to Empathy?

Empathy is the basis of a patient-physician relationship; however, this is being lost by students throughout medical training. Immersive virtual reality that allows individuals to viscerally experience anything from another person's point of view has the potential to reverse the erosion of empathy and improve clinical practices.

Due Process in Medical Education: Legal Considerations.

Throughout the medical education continuum, some students encounter difficulty in meeting academic or professional standards that leads to remediation or dismissal. Termination of a student without due process may lead to litigation by deprivation of a student's property or liberty interest. This article outlines the concept of procedural and substantive due process as applied to litigated student dismissal cases in undergraduate and graduate medical education. Determination of the amount of due process owed is based on whether the dismissal is academic or nonacademic. The decision to dismiss a student where the entire student record has been reviewed, due process provided, and the institution complied with its own policies is usually upheld by the courts in litigation.

FRAP analysis of chemosensory components of Dictyostelium.

Dictyostelium discoideum is a useful cell model for studying protein-protein interactions and deciphering complex signaling pathways similar to those found in mammalian systems. Many of these interactions were analyzed using classical in vitro biochemical techniques. However, with the accessibility of fluorescently tagged proteins, extensive protein networks are now being mapped out in living cells using a variety of microscopic techniques. One such technique, fluorescent recovery after photobleaching (FRAP), has been used in Dictyostelium to investigate a number of cellular processes including actin and cytoskeleton dynamics during chemotaxis and cytokinesis (J. Muscle Res. Cell Motil. 23:639-649, 2002; Biophys. J. 81:2010-2019, 2001; Mol. Biol. Cell 16:4256-4266, 2005), to follow trafficking of proteins to organelles such as the membrane, nucleus, and endoplasmic reticulum (Development 130:797-804, 2003; J. Cell Biol. 154:137-146, 2001), and to understand the role of proteins in cell adhesion during motility and division (Mol. Biol. Cell 18:4074-4084, 2007; J. Cell Sci. 120:4302-4309, 2007). FRAP is a powerful tool that should provide a vast amount of information on the mobility of a number of proteins, not only in Dictyostelium, but in many organisms. This study will lay out the methods of conducting FRAP experiments in Dictyostelium and discuss the large amount of knowledge which can be gained by adopting this as a common technique.

Dynamic localization of G proteins in Dictyostelium discoideum.

Extracellular stimuli exert their effects on eukaryotic cells via serpentine G-protein-coupled receptors and mediate a vast number of physiological responses. Activated receptors stimulate heterotrimeric G-proteins, consisting of three subunits, alpha, beta and gamma. In Dictyostelium discoideum, cAMP binds to the cAMP receptor cAR1, which is coupled to the heterotrimer containing the Galpha2 subunit. These studies provide in vivo evidence as to how receptors influence the localization of the G-protein complex prior to and after ligand binding. Previous work has shown that the state of the heterotrimer could be monitored by changes in fluorescence (or Förster) resonance energy transfer (FRET) between the alpha2- and beta-subunits of D. discoideum. We now report the kinetics of G-protein activation as a loss of FRET prior to and after cAMP addition by using total internal reflection fluorescence microscopy (TIRFM). We also performed photobleaching experiments to measure G-protein recovery times. Our data show that inactive and active G-proteins cycle between the cytosol and plasma membrane. These data suggest that cAR1 activation slows the membrane dissociation ('off') rate of the alpha2 subunit, while simultaneously promoting betagamma-subunit dissociation.

Thrombospondin 1 binding to calreticulin-LRP1 signals resistance to anoikis.

Anoikis, apoptotic cell death due to loss of cell adhesion, is critical for regulation of tissue homeostasis in tissue remodeling. Fibrogenesis is associated with reduced fibroblast apoptosis. The matricellular protein thrombospondin 1 (TSP1) regulates cell adhesion and motility during tissue remodeling and in fibrogenesis. The N-terminal domain of TSP1 binds to the calreticulin-LRP1 receptor co-complex to signal down-regulation of cell adhesion and increased cell motility through focal adhesion disassembly. TSP1 signaling through calreticulin-LRP1 activates cell survival signals such as PI3-kinase. Therefore, we tested the hypothesis that TSP1 supports cell survival under adhesion-independent conditions to facilitate tissue remodeling. Here, we show that platelet TSP1, its N-terminal domain (NoC1) as a recombinant protein, or a peptide comprising the calreticulin-LRP1 binding site [amino acids 17-35 (hep I)] in the N-terminal domain promotes fibroblast survival under anchorage-independent conditions. TSP1 activates Akt and decreases apoptotic signaling through caspase 3 and PARP1 in suspended fibroblasts. Inhibition of PI3K/Akt activity blocks TSP1-mediated anchorage-independent survival. Fibroblasts lacking LRP1 or expressing calreticulin lacking the TSP1 binding site do not respond to TSP1 with anchorage-independent survival. These data define a novel role for TSP1 signaling through the calreticulin/LRP1 co-complex in tissue remodeling and fibrotic responses through stimulation of anoikis resistance.-Pallero, M.

Thrombospondin signaling through the calreticulin/LDL receptor-related protein co-complex stimulates random and directed cell migration.

The matricellular extracellular matrix protein thrombospondin-1 (TSP1) stimulates focal adhesion disassembly through a sequence (known as the hep I peptide) in its heparin-binding domain. This mediates signaling through a receptor co-complex involving calreticulin and low-density lipoprotein (LDL) receptor-related protein (LRP). We postulate that this transition to an intermediate adhesive state enhances cellular responses to dynamic environmental conditions. Since cell adhesion dynamics affect cell motility, we asked whether TSP1/hep I-induced intermediate adhesion alters cell migration. Using both transwell and Dunn chamber assays, we demonstrate that TSP1 and hep I gradients stimulate endothelial cell chemotaxis. Treatment with focal adhesion-labilizing concentrations of TSP1/hep I in the absence of a gradient enhances endothelial cell random migration, or chemokinesis, associated with an increase in cells migrating, migration speed, and total cellular displacement. Calreticulin-null and LRP-null fibroblasts do not migrate in response to TSP1/hep I, nor do endothelial cells treated with the LRP inhibitor receptor-associated protein (RAP). Furthermore, TSP1/hep I-induced focal adhesion disassembly is associated with reduced chemotaxis to basic fibroblast growth factor (bFGF) but enhanced chemotaxis to acidic (a)FGF, suggesting differential modulation of growth factor-induced migration. Thus, TSP1/hep I stimulation of intermediate adhesion regulates the migratory phenotype of endothelial cells and fibroblasts, suggesting a role for TSP1 in remodeling responses.

Low density lipoprotein receptor-related protein is a calreticulin coreceptor that signals focal adhesion disassembly.

Thrombospondin (TSP) signals focal adhesion disassembly (the intermediate adhesive state) through interactions with cell surface calreticulin (CRT). TSP or a peptide (hep I) of the active site induces focal adhesion disassembly through binding to CRT, which activates phosphoinositide 3-kinase (PI3K) and extracellular signal-related kinase (ERK) through Galphai2 proteins. Because CRT is not a transmembrane protein, it is likely that CRT signals as part of a coreceptor complex. We now show that low density lipoprotein receptor-related protein (LRP) mediates focal adhesion disassembly initiated by TSP binding to CRT. LRP antagonists (antibodies, receptor-associated protein) block hep I/TSP-induced focal adhesion disassembly. LRP is necessary for TSP/hep I signaling because TSP/hep I is unable to stimulate focal adhesion disassembly or ERK or PI3K signaling in fibroblasts deficient in LRP. LRP is important in TSP-CRT signaling, as shown by the ability of hep I to stimulate association of Galphai2 with LRP. The isolated proteins LRP and CRT interact, and LRP and CRT are associated with hep I in molecular complexes extracted from cells. These data establish a mechanism of cell surface CRT signaling through its coreceptor, LRP, and suggest a novel function for LRP in regulating cell adhesion.
