RESUMEN
BACKGROUND: Congenital diaphragmatic hernia (CDH) is a complex birth anomaly with significant mortality and morbidity. Lung hypoplasia and persistent pulmonary hypertension (PPHN) limit survival in CDH. Macrophage migration inhibitory factor (MIF), a key regulator of innate immunity, is involved in hypoxia-induced vascular remodeling and PPHN. We hypothesized that antenatal inhibition of MIF in CDH fetuses, would reduce vascular remodeling, and improve angiogenesis and lung development. METHODS: Pregnant rats were randomized into three groups: Control, nitrofen, and nitrofen + ISO-92. Lung volumes of pups were measured by CT scanning. Right ventricular systolic pressure (RVSP) and vascular wall thickness (VWT) were measured together with MIF concentration, angiogenesis markers, lung morphometry, and histology. RESULTS: Prenatal treatment with ISO-92, an MIF inhibitor, improved normalization of static lung volume, lung volume-to-body weight ratio, decreased alveolar septal thickness, RVSP and VWT and improved radial alveolar count as compared to the non-treated group. Expression of MIF was unaffected by ISO-92; however, ISO-92 increased p-eNOS and VEGF activities and reduced arginase 1, 2 and Sflt-1. CONCLUSION: Prenatal inhibition of MIF activity in CDH rat model improves angiogenesis and lung development. This selective intervention may be a future therapeutic strategy to reduce the morbidity and mortality of this devastating condition.

Despite the many clerkship models of medical education, all can be considered a form of experiential learning. Experiential learning is a complex pedagogical approach involving the development of cognitive skills in an environment with a unique culture with multiple stakeholders, which may impact learner motivation, confidence, and other noncognitive drivers of success. Students may delay the transition to the clerkship year for myriad reasons, and the intricate nature of experiential learning suggested this may impact student performance. This retrospective, observational study investigated the impact of clerkship postponement by measuring subsequent clerkship performance. Pre-clerkship and third-year clerkship performance were analyzed for three cohorts of students (classes of 2018, 2019, and 2020, N = 274) where students had the option to delay the start of their clerkship year. A mixed analysis of variance (ANOVA) and paired t-tests were conducted to compare academic performance over time among students who did and did not delay. Across three cohorts of students, 12% delayed the start of the clerkship year (N = 33). Regardless of prior academic performance, these students experienced a significant reduction in clerkship grades compared to their non-delaying peers. Delaying the start of the clerkship year may have negative durable effects on future academic performance. This information should be kept in mind for student advisement.

BACKGROUND: The Medical Student Performance Evaluation (MSPE) provides important information to residency programs. Despite recent recommendations for standardization, it is not clear how much variation exists in MSPE content among schools. OBJECTIVES: We describe the current section content of the MSPE in US allopathic medical schools, with a particular focus on variations in the presentation of student performance. METHODS: A representative MSPE was obtained from 95.3% (143 of 150) of allopathic US medical schools through residency applications to the Zucker School of Medicine at Hofstra/Northwell in select programs for the 2019-2020 academic year. A manual data abstraction tool was piloted in 2018-2019. After training, it was used to code all portions of the MSPE in this study. The results were analyzed, and descriptive statistics were reported. RESULTS: In preclinical years, 30.8% of MSPEs reported data regarding performance of students beyond achieving "passes" in a pass/fail curriculum. Only half referenced performance in the fourth year including electives, acting internships, or both. About two-thirds of schools included an overall descriptor of comparative performance in the final paragraph. Among these schools, a majority provided adjectives such as "outstanding/excellent/very good/good," while one-quarter reported numerical data categories. Regarding clerkship grades, there were numerous nomenclature systems used. CONCLUSIONS: This analysis demonstrates the existence of extreme variability in the content of MSPEs submitted by US allopathic medical schools in the 2019-2020 cycle, including the components and nomenclature of grades and descriptors of comparative performance, display of data, and inclusion of data across all years of the medical education program.

OBJECTIVE: Alcohol use among survivors of head and neck cancer (HNC) negatively impacts patient outcomes and is an important risk factor for recurrent and second primary tumors. Despite recommendations from several cancer societies, alcohol consumption remains a common problem in this population. METHODS: A cross-sectional study was performed with the Alcohol Use Disorders Identification Test (AUDIT) Self-Report questionnaire. Patients with HNC completed surveys at pre-treatment and follow-up appointments every 3-6 months for at least 2-years after treatment. RESULTS: 796 surveys were available for analysis. Most participants were male (75.7%) and had either oropharyngeal (34.5%) or laryngeal (16.7%) cancer. The percentage of alcohol drinkers decreased from 56.1% at pre-treatment to 40.4% at 0-3 months post-treatment, but then increased and surpassed baseline levels by 24 + months post-treatment (64.4%, p = 0.0079). Concurrently, moderate drinkers (AUDIT = 1 - 3) decreased from 34.2% at pre-treatment to 25.2% at 0-3 months post-treatment, but then increased and surpassed baseline levels at 24 + months post-treatment (39.7%, p = 0.0129). Trends among heavy (AUDIT > 3), and heaviest (AUDIT > 6) drinkers were similar, but not statistically significant. At 24 + months post-therapy, we observed a statistically significant increase in female users (39.1% to 63.2%, p = 0.0213) and moderate drinkers < 55 years old (43.4% to 61.9%, p = 0.0184). CONCLUSION: Alcohol consumption in survivors of HNC transiently decreases in the immediate months after treatment, but then increases and remains largely stable by 24 months. This pattern is particularly concerning and highlights the need for timely interventions.

OBJECTIVE: To report the early experience using an automated chatbot (Chats)for patient-reported outcomes (PRO) and symptom self-managementinhead and neck cancer (HNC) patients undergoing radiation treatment (RT). METHODS: Patients aged ≥ 18 yearsdiagnosed with HNC who were scheduled to begin RT were given the option to use Chats from June 2018 to June 2019. Enrolled patients received chat notifications two days before weekly on-treatment visitsand every 1-4 weeks after RT for an additional 4 months. After the first in-person follow-up visit, participants completed an electronic usability and satisfaction questionnaire. RESULTS: Of 95 patients who agreed to participate, 84 were eligible for analysis.Participantswere significantly younger than patients who declined participation (mean age 61.3 vs 68.3 years;p-value < 0.001). Patient engagement with Chats was highest at 67% during the first month and declined over time (p-value = 0.004). Concordance between PRO and clinician-reported outcomes (CRO) was fair, ranging from 0.10 to 0.43 (Cohen κ statistics). The most commonly under-reported symptoms were salivary duct inflammation (53%), xerostomia (41%), and mucositis (37%). 89% (39 of 44) of patients who completed surveys found Chats easy to use, and 61% reported that Chats helped with symptom self-management and reduced the need to call the care team. CONCLUSIONS: These early results suggest that an interactive chatbot is feasible and provides support for HNC patients during and after RT. Chats identified discordance between PRO and CRO. Further study is required to measure benefits of Chats in a larger population.

BACKGROUND: Patients with head and neck cancer (HNC) frequently experience disease-related symptoms and treatment adverse effects that impact their overall quality of life. Cancer-specific mobile health apps for patient-related outcomes allow patients to communicate with their clinicians and proactively track their symptoms, which have been shown to improve clinical management and disease outcomes. OBJECTIVE: The purpose of this study was to evaluate the feasibility of LogPAL, a novel iPhone-based mobile health app designed to help HNC survivors track and manage their posttreatment symptoms. METHODS: Patients who completed curative treatment for HNC in the preceding 24 months were recruited from 2 clinical sites within a single institution. Upon enrollment, participants completed a brief sociodemographic survey, downloaded the app onto their iPhone devices, and were asked to complete a series of biweekly questionnaires (based on the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events) via the app for an 8-week study period. The primary feasibility endpoints included retention (retaining >80% of the enrolled participants for the duration of the study period), adherence (>50% of the participants completing 100% of the questionnaires over the study period), and usability (a mean system usability scale [SUS] score >68). Additional postintervention questions were collected to assess perceived usefulness, acceptance, and overall satisfaction. RESULTS: Between January and October 2019, 38 participants were enrolled in the study. Three participants dropped out, and 3 were classified as nonusers. The remaining 32 (87%) were eligible for analysis. Their mean age was 57.8 (SD 12.3) years (range 24-77 years, 81% [26/32] male). Overall, 375 of 512 (73.2%) questionnaires were completed, with 17 (53%) of the 32 participants adherent. Participant-reported usability was acceptable; the mean SUS score was 71.9 (95% CI 64.3-79.5) with high satisfaction of LogPAL usefulness and likelihood to recommend to other cancer survivors. CONCLUSIONS: This single-arm prospective pilot study showed that LogPAL is a feasible, regularly used, accepted app for HNC survivors, justifying a full-scale pilot. Based on the findings from this study, future iterations will aim to improve usability and test intervention efficacy.
RESUMEN
This article was migrated. The article was marked as recommended. Introduction: Resident as Teacher (RaT) curriculum continues to be recognized as a critical component of residents' education. However, in busy clinical workplaces, there are time constraints limiting formal training for RaT. This study aimed to assess the engagement and acceptability of Just-in-Time-Teaching (JiTT) infographics, a novel RaT tool that provides digestible evidence-based knowledge & skills at the time & place where teaching happens. Methods: The study focused on residents and faculty between July - September 2019, across 12 residency programs in six specialties. JiTT infographics were distributed weekly for six weeks. Engagement of residents was measured by open rates of infographics. Acceptability was evaluated using mixed-methods analysis of a questionnaire at the conclusion of the study, and a focus group with appointed resident and faculty champions. Descriptive statistical analyses were applied to ascertain preliminary results. Results: Overall, 76.2% (198/260) of residents opened infographics, with an average engagement rate of 64.9% Analysis of acceptability evaluations revealed infographics to be effective and had a positive impact on teaching style. Discussion and Conclusion: JiTT infographics function as an educational approach to support teaching strategies in the busy clinical setting. It can be adapted across diverse programs and integrated into a teaching toolbox for residents and faculty.

Dendritic spines are small protrusions that serve as the principal recipients of excitatory inputs onto cortical pyramidal cells. Alterations in spine and filopodia density and morphology correlate with both developmental maturity and changes in synaptic strength. In order to better understand the developmental profile of dendritic protrusion (dendritic spines + filopodia) morphology and density over the animal's first postnatal year, we used the Golgi staining technique to label neurons and their dendritic protrusions in mice. We focused on quantifying the density per length of dendrite and categorizing the morphology of dendritic protrusions of layer VI pyramidal neurons residing in barrel cortex using the computer assisted reconstruction program Neurolucida. We classified dendritic protrusion densities at seven developmental time points: postnatal day (PND) 15, 30, 60, 90, 180, 270, and 360. Our findings suggest that the dendritic protrusions in layer VI barrel cortex pyramidal neurons are not static, and their density as well as relative morphological distribution change over time. We observed a significant increase in mushroom spines and a decrease in filopodia as the animals matured. Further analyses show that as the animal mature there was a reduction in pyramidal cell dendritic lengths overall, as well as a decrease in overall protrusion densities. The ratio of apical to basilar density decreased as well. Characterizing the profile of cortical layer VI dendritic protrusions within the first postnatal year will enable us to better understand the relationship between the overall developmental maturation profile and dendritic spine functioning.
