RESUMEN
Background: Academic inquiry is foundational to the advancement of medicine and resident training and must be demonstrated to the Accreditation Council for Graduate Medical Education. Past attempts at increasing publication rates have failed to identify educational best practice models. Our aim was to increase resident publication rates via culture and value changes that are universally implementable, affordable, effective, and sustainable. Methods: In 2018, a multifaceted initiative was implemented to shift departmental values and foster a culture of academic productivity. This culture change stressed the value of scientific publication through frequent, consistent messaging from department leaders. In addition, residents were provided the freedom to choose their scholarly activities. In this retrospective cohort innovation, resident authors were identified for 4 academic years before and after the intervention and publication rates were determined (2014-2018 vs 2018-2022). Resident authors and publications per resident per year were compared using descriptive statistics and Student t test. Results: The pre- and postintervention groups included 38 and 37 residents, respectively. Resident-authored publications increased from 7 preintervention to 24 postintervention, representing 343% of baseline. Mean ± SD publications per resident per year similarly increased 357% from 0.183 ± 0.16 to 0.654 ± 0.11 postintervention. Unpaired t test analysis demonstrated a significant difference in total publications per year (P = .002) and authorship rate (P = .003). Conclusions: A multifaceted academic initiative resulted in a threefold increase in resident publication rates. This initiative demonstrates that local advocacy by leaders, freedom of choice for authors, and supportive departmental culture are driving factors in publication rates.
RESUMEN
One of the earliest patterning events in the vertebrate neural plate is the specification of mes/r1, the territory comprising the prospective mesencephalon and the first hindbrain rhombomere. Within mes/r1, an interface of gene expression defines the midbrain-hindbrain boundary (MHB), a lineage restriction that separates the mesencephalon and rhombencephalon. wnt1 is critical to mes/r1 development and functions within the MHB as a component of the MHB gene regulatory network (GRN). Despite its importance to these critical and early steps of vertebrate neurogenesis, little is known about the factors responsible for wnt1 transcriptional regulation. In the zebrafish, wnt1 and its neighboring paralog, wnt10b, are expressed in largely overlapping patterns, suggesting co-regulation. To understand wnt1 and wnt10b transcriptional control, we used a comparative genomics approach to identify relevant enhancers. We show that the wnt1-wnt10b locus contains multiple cis-regulatory elements that likely interact to generate the wnt1 and wnt10b expression patterns. Two of 11 conserved enhancers tested show activity restricted to the midbrain and MHB, an activity that is conserved in the distantly related spotted gar orthologous elements. Three non-conserved elements also play a likely role in wnt1 regulation. The identified enhancers display dynamic modes of chromatin accessibility, suggesting controlled deployment during embryogenesis. Our results suggest that the control of wnt1 and wnt10b expression is under complex regulation involving the interaction of multiple enhancers.

OBJECTIVE: Describe the change in intraoperative transcatheter aortic valve replacement (TAVR) care by examining the utilization of transesophageal echocardiography (TEE) versus transthoracic echocardiography (TTE) and general anesthesia (GA) versus conscious sedation (CS) over time. DESIGN: Retrospective, observational. SETTING: A university, single, high-volume TAVR center. PARTICIPANTS: Patients who underwent TAVR. INTERVENTIONS: Retrospective data collection from the electronic medical records on TAVR patients at a single institution from March 1, 2014 to August 31, 2017. The intraoperative echocardiographic modality, anesthetic type, Society of Thoracic Surgeons (STS) operative mortality risk score, and date each new TAVR valve first was employed at the institution were recorded. MEASUREMENTS AND MAIN RESULTS: Data were analyzed using descriptive statistics apportioned into 6-month intervals. The Fisher exact test and chi-square test were used to test the association of anesthesia type and echocardiography over time, respectively. STS score, anesthetic type, and echocardiographic type were compared using the Wilcoxon rank sum test. Analysis showed increased use of TTE and CS, from 0% and 0% intially to 68.42% and 63.16% most recently (p < 0.0001). In the final study period (after March 1, 2017), the use of TTE and CS surpassed TEE and GA, respectively. STS scores were significantly higher among patients having TEE versus TTE (median STS 6.34 v 4.45, respectively [pâ¯=â¯0.0047]) and GA versus CS (median STS 6.36 v 4.37, respectively [pâ¯=â¯0.0090]). CONCLUSION: Although TAVR initially was conducted exclusively under GA with TEE, nearly two-thirds of TAVR procedures now are performed using CS and TTE at the authors' institution. STS scores were significantly lower in patients having CS and TTE.
