RESUMO

OBJECTIVE: The aim of this study was to develop and validate an instrument to measure Belonging in Surgery among surgical residents. SUMMARY BACKGROUND DATA: Belonging is the essential human need to maintain meaningful relationships and connections to one's community. Increased belongingness is associated with better well-being, job performance and motivation to learn. However, no tools exist to measure belonging among surgical trainees. METHODS: A panel of experts adapted a belonging instrument for use among United States surgery residents. After administration of the 28-item instrument to residents at a single institution, a Cronbach's alpha was calculated to measure internal consistency, and exploratory principal component analyses (PCA) were performed. Multiple iterations of analyses with successively smaller item samples suggested the instrument could be shortened. The expert panel was reconvened to shorten the instrument. Descriptive statistics measured demographic factors associated with Belonging in Surgery. RESULTS: The overall response rate was 52% (114 responses). The Cronbach's alpha among the 28 items was 0.94 (95% CI: 0.93-0.96). The exploratory PCA and subsequent Promax rotation yielded one dominant component with an eigenvalue of 12.84 (70% of the variance). The expert panel narrowed the final instrument to 11 items with an overall Cronbach's alpha of 0.90 (95% CI: 0.86, 0.92). Belonging in Surgery was significantly associated with race (Black and Asian residents scoring lower than White residents), graduating with one's original intern cohort (residents who graduated with their original class scoring higher than those that did not), and inversely correlated with resident stress level. CONCLUSIONS: An instrument to measure Belonging in Surgery was validated among surgical residents. With this instrument, Belonging in Surgery becomes a construct that may be used to investigate surgeon performance and well-being.

RESUMO

Hybridization of eggs and sperm from closely related species can give rise to genetic diversity, or can lead to embryo inviability owing to incompatibility. Although central to evolution, the cellular and molecular mechanisms underlying post-zygotic barriers that drive reproductive isolation and speciation remain largely unknown. Species of the African clawed frog Xenopus provide an ideal system to study hybridization and genome evolution. Xenopus laevis is an allotetraploid with 36 chromosomes that arose through interspecific hybridization of diploid progenitors, whereas Xenopus tropicalis is a diploid with 20 chromosomes that diverged from a common ancestor approximately 48 million years ago. Differences in genome size between the two species are accompanied by organism size differences, and size scaling of the egg and subcellular structures such as nuclei and spindles formed in egg extracts. Nevertheless, early development transcriptional programs, gene expression patterns, and protein sequences are generally conserved. Whereas the hybrid produced when X. laevis eggs are fertilized by X. tropicalis sperm is viable, the reverse hybrid dies before gastrulation. Here we apply cell biological tools and high-throughput methods to study the mechanisms underlying hybrid inviability. We reveal that two specific X. laevis chromosomes are incompatible with the X. tropicalis cytoplasm and are mis-segregated during mitosis, leading to unbalanced gene expression at the maternal to zygotic transition, followed by cell-autonomous catastrophic embryo death. These results reveal a cellular mechanism underlying hybrid incompatibility that is driven by genome evolution and contributes to the process by which biological populations become distinct species.

RESUMO

PURPOSE: Goal orientation (GO) is a psychological construct which describes an individual's intrinsic motivation for learning in terms of mastery and performance goals. Mastery goals relate to the intrinsic drive to learn for the sake of learning, while performance goals are oriented toward validating one's own competence by seeking favorable judgments (Performance Approach; PAP) or avoiding negative judgments (Performance Avoid; PAV). Having a mastery GO has been shown to improve overall job satisfaction as well as optimize job performance. We therefore aimed to examine how GO changes during the transition to residency, which is a notoriously challenging period in medical education, and identify interventions that can increase mastery of GO. METHODS: The validated Goal Orientation in Surgical Trainees (GO-ST) instrument was administered to incoming surgical interns (n = 19) during orientation in a single, university-based program and again at 3 months into the internship. The perceived stress scale (PSS) was also administered at 3 months. Focus groups were used to assess resident perceptions and identify interventions at the end of the 3-month period. RESULTS: Eighteen interns (95%) completed a baseline GO-ST assessment and the 3-month follow-up, including the PSS. Mastery GO decreased from orientation to 3-month follow-up for the entire cohort, but this was not significant (3.89-3.63; p = 0.19). Preliminary interns showed a significant increase in PAV orientation after 3 months (3.28-3.67; p = 0.04) and had significantly lower mastery orientation scores at this time (4.07 vs 3.19; p = 0.02). PSS was significantly higher in preliminary interns at 3 months (18.56 vs 11.89; p = 0.04). Those who were predominantly mastery oriented had significantly lower perceived stress scores (11.64 vs 20.10; p = 0.002) compared with those that had performance goal orientations (PAP and PAV). Five interns (28%) participated in focus groups-identifying pertinent themes: 1) Perceptions of competence, 2) Training security; 3) Feedback approach, 4) Expectations of competence, and 5) Approaches to growth. CONCLUSION: Mastery GO declines during the transition to surgical residency. Maladaptive PAV orientation increases in preliminary interns due to different short-term priorities and assumptions of competence. Expectations and perceptions of intern competence by senior residents and attendings have a large impact on intern GO. Identifying interventions that optimize mastery goal orientation and minimize performance avoid orientation will potentially minimize intern stress, thereby improving both well-being and clinical performance.

RESUMO

IMPORTANCE: Following the recent expansion of telemedicine during the COVID-19 pandemic, this remote model of care in female pelvic medicine and reconstructive surgery will likely remain and continue to evolve. OBJECTIVE: This study was conducted to assess patients' perceptions of and willingness to participate in a synchronous telemedicine visit beyond the COVID-19 pandemic for women with pelvic floor disorders. STUDY DESIGN: We conducted a cross-sectional study of women who completed a synchronous telemedicine visit from March 16 through May 22, 2020, at a urogynecology practice in an academic medical center. An electronic survey was distributed to women after all telemedicine visits. Demographic data, visit type, and survey responses were analyzed. RESULTS: Two hundred two women received the survey, and 135 women completed it (response rate of 66.8%). The mean age of the respondents was 62.9 ± 16.4 years, and the 3 most common visit diagnoses were overactive bladder (43.7%), stress urinary incontinence (22.2%), and pelvic organ prolapse (21.4%). Most survey participants (88.9%) found that the quality of their telemedicine visits was better than expected, and 89.6% reported that they would like to continue telemedicine care. Our survey showed that 19.4% of women reported difficulty with technology. CONCLUSIONS: We found that most women presenting for synchronous telemedicine urogynecology care had a positive visit experience and would continue to use telemedicine for their care. Further developmental work needs to be done on improving the ease of technology as well as availability of telemedicine in the care of women affected by pelvic floor disorders.

RESUMO

BACKGROUND: Diversity in surgery lags behind the medical student population. We documented first-year medical students' vulnerability to stereotype threat (VST) and its impact on a sense of belonging in surgery. METHODS: All first-year medical students at a single academic institution were surveyed. Demographics, VST, anticipated clerkship experience, and sense of belonging were assessed. RESULTS: 44% of students were vulnerable to ST in upcoming clerkships, with the majority worried about surgical clerkships. More student from races/ethnicities underrepresented in medicine (URM; 74%) and sexual minorities (62%) were vulnerable than white (30%) and heterosexual (38%) students respectively (p = 0.001 and p = 0.017). Knowing a surgeon with a shared identity would enhance belonging for most students (84%). VST was higher for those who do not anticipate working with (p < 0.001) or do not know a surgeon (p = 0.0001) who shares their identity. CONCLUSION: VST significantly influences a student's sense of belonging in surgery. More research is needed to promote inclusivity in surgery.

RESUMO

BACKGROUND: Medical students have negative perceptions of surgery prior to their clerkships. To explore possible explanations, we examined the association between these perceptions, individual identity and vulnerability to stereotype threat (ST). METHODS: All first-year medical students at a single school received an electronic survey which assessed identity groups, vulnerability to ST and perceptions of surgeons/surgery. Multi-method analyses examined these associations. RESULTS: Women held more negative than positive views about the field of surgery (p = 0.007) but not surgeons. Students vulnerable to ST had negative views about both surgeons (p < 0.0001) and surgery (p = 0.007). They were also less interested in pursuing a surgical career compared to non-vulnerable students (56% vs. 80% p = 0.03). CONCLUSION: For some students, negative views of surgeons and surgery appear to be associated with individual identity and ST. Future research should aim to confirm these findings and identify strategies to develop positive perceptions for these populations.

RESUMO

PURPOSE: The conflict between prioritizing education for surgical trainees, promoting trainee wellness, and maintaining optimal patient care has remained challenging since the introduction of the Accreditation Council for Graduate Medical Education (ACGME) work hour restrictions in 2003. There is still a dearth of research examining which interventions successfully enable duty hour adherence. This study assessed the impact of a combination of strategic interventions on improving clinical work hour adherence. METHODS: Monthly clinical work hour submission rates were assessed for all general surgery residents at a single university-based residency program over a 3-year period (2018-2021). Interventions targeted 3 domains and were implemented between academic years 2018 to 2019 (control) and 2020 to 2021 (intervention): 1) improving the accuracy and transparency of work hour reporting, 2) facilitating more timely interventions, and 3) structural scheduling changes. All 80-hour work week and continuous work hour violations were assessed. Findings were also compared to the corresponding ACGME Resident Survey results. RESULTS: There was no significant difference in the rate of monthly work hour submissions pre- and postintervention (78% vs 75%, p = 0.057). However, the number of total reported monthly violations decreased significantly (mean 13.8 vs 2.4, p < 0.01), including decreases in both 80-hour work week and continuous work hour violations (mean 4.7 vs 1.6, p < 0.001 and 9.1 vs 0.8, p < 0.001, respectively). Reported compliance also increased on the annual ACGME resident surveys, where 61% vs 95% of residents felt they were compliant with the 80-hour work week and 71% vs 95% felt they were compliant with the continuous work hours (2018-19 vs 2020-21). CONCLUSION: Innovative strategies addressing schedule changes, the culture of work hour reporting, and early intervention significantly decreased the number of duty hour violations at our institution. Reported resident compliance also improved based on ACGME Resident Survey data. These data may inform similar multifaceted approaches at other institutions to improve overall work hour adherence.

RESUMO

BACKGROUND: The surgical clerkship is the primary surgical learning experience for medical students. This study aims to understand student perspectives on the surgery clerkship both before and after the core surgical rotation. METHODS: Medical students at 4 academic hospitals completed pre and postclerkship surveys that included open-ended questions regarding (1) student learning goals and concerns and (2) how surgical clerkship learning could be enhanced. Thematic analysis was performed, and interrater reliability was calculated. RESULTS: Ninety-one percent of students completed both a pre and postclerkship survey (n =162 of 179), generating 320 preclerkship and 270 postclerkship responses. Mean kappa coefficients were 0.83 and 0.82 for pre and postclerkship primary themes, respectively. Thematic analysis identified 5 broad themes: (1) core learning expectations, (2) understanding surgical careers, culture, and work, (3) inhabiting the role of a surgeon, (4) inclusion in the surgical team, and (5) the unique role of the medical student on clinical clerkships. Based on these themes, we propose a learner-centered model of a successful surgical clerkship that satisfies discrete student learning and goals and career objectives while ameliorating the challenges of high-stakes clinical surgical environments such as the operating room. CONCLUSION: Understanding student perspectives on the surgery clerkship, including preclerkship motivations and concerns and postclerkship reflections on surgical learning, revealed potential targets of intervention to improve the surgery clerkship. Future investigation may elucidate whether the proposed model of the elements of a successful surgery clerkship learning facilitates improvement of the surgical learning environment and enhanced surgical learning.

RESUMO

Determining how size is controlled is a fundamental question in biology that is poorly understood at the organismal, cellular, and subcellular levels. The Xenopus species, X. laevis and X. tropicalis differ in size at all three of these levels. Despite these differences, fertilization of X. laevis eggs with X. tropicalis sperm gives rise to viable hybrid animals that are intermediate in size. We observed that although hybrid and X. laevis embryogenesis initiates from the same sized zygote and proceeds synchronously through development, hybrid animals were smaller by the tailbud stage, and a change in the ratio of nuclear size to cell size was observed shortly after zygotic genome activation (ZGA), suggesting that differential gene expression contributes to size differences. Transcriptome analysis at the onset of ZGA identified twelve transcription factors paternally expressed in hybrids. A screen of these X. tropicalis factors by expression in X. laevis embryos revealed that Hes7 and Ventx2 significantly reduced X. laevis body length size by the tailbud stage, although nuclear to cell size scaling relationships were not affected as in the hybrid. Together, these results suggest that transcriptional regulation contributes to biological size control in Xenopus.
