Picture this: A novel model eye for ophthalmoscopy practice.

WHAT WAS THE EDUCATIONAL CHALLENGE?: Ophthalmoscopy is a challenging skill to learn but essential for identifying ophthalmic pathology. Typically, there are few opportunities for early learners to practice this skill in the non-clinical setting. WHAT WAS THE SOLUTION?: We sought to develop a model eye for the practice of direct and indirect ophthalmoscopy, with realistic dimensions and fundus images, using accessible and affordable supplies. HOW WAS THE SOLUTION IMPLEMENTED?: A simple model eye was created with over-the-counter materials. A free software program was used to modify fundus photographs so that they could be molded to the posterior pole of the model eye. WHAT LESSONS WERE LEARNED THAT ARE RELEVANT TO A WIDER GLOBAL AUDIENCE?: This model eye can be implemented globally given the simple and affordable construction process to facilitate practice of the ophthalmoscopy technique. WHAT ARE THE NEXT STEPS?: Formally assessing the efficacy of our model eye teaching tool with learners, using both self-reported and objective methods.

Prevalence of Women in Medicine Programs at University-Based Internal Medicine Residency Programs.

OBJECTIVE: Women physicians face various forms of inequities during their training process that inhibit them from reaching their full potential. As a response, several academic institutions have established women in medicine (WIM) programs as a support system. Our objective was to investigate the prevalence of WIM programs at university-based Internal Medicine residency programs as of December 2021. METHODS: Using the Fellowship and Residency Electronic Interactive Database, we identified 145 university-based Internal Medicine residency programs. Four independent reviewers reviewed the programs' Web sites, looking for evidence of a WIM program using a standardized checklist of search terms to evaluate and categorize their programs. Categories included whether the program was specific to graduate medical trainees, departments of medicine, or institution-wide. The proportions of programs that had a WIM program, a trainee-specific WIM program, and a Department of Medicine-specific WIM program were then analyzed. RESULTS: Of the 145 programs searched, 58 (40%) had a WIM program. Only 16 (11%) were specific to trainees (11 for only medicine trainees and 5 included trainees graduate medical education-wide). The remaining 42 programs targeted faculty and trainees (5 included only the Department of Medicine and 37 included departments university-wide). CONCLUSIONS: Few university-affiliated Internal Medicine residency programs have a WIM program specific to trainees. Given the gender inequity and evidence that supports early development of leadership skills and support networks, our findings highlight a possible gap in the residency training program infrastructure.

Perceptions of Gender Stereotypes among Women Residents in Surgical and Nonsurgical Specialties.

OBJECTIVE: The objective of this study was to determine whether and to what degree residents experience stereotype perception by gender and specialty type (surgical vs nonsurgical). METHODS: A cross-sectional survey was sent to resident physicians across all specialties at a single academic institution in February 2021. The survey items asked whether participants believe residents, faculty, and the public expect men or women to be better physicians on a numerical scale from 1 to 7. A χ2 test compared the calculated mean and standard error for each survey item. This study took place at Washington University School of Medicine in St. Louis, Missouri, a large academic tertiary care center. RESULTS: A total of 411 (46% of total) residents participated; 13 were excluded because of nonbinary gender or missing demographic information, for a final sample of 398. Participants perceived all three groups to expect men to be better physicians than women. Regression analysis showed a significant effect of gender on stereotype perception, with women reporting stronger stereotype perceptions than men. There were no significant differences in stereotype perceptions by specialty type. CONCLUSIONS: Women resident physicians in both surgical and nonsurgical fields reported higher levels of gender stereotype perception compared with men, making it imperative that graduate medical education leadership support changes to the current learning environment.

Investing in Women Trainees: Building a Women in Medicine Group at an Academic Institution.

Given the importance of proactively supporting women trainees in medicine to address gender inequities, we draw on the experience of a well-established professional development initiative to provide a framework for other institutions seeking to create similar trainee-focused programs.

Outcomes of Mesh Cranioplasty in Scalp-Free Tissue Reconstruction: A Systematic Review and Meta-analysis.

OBJECTIVE: To systematically review the literature to determine the prevalence and risk of the free flap and postoperative complications in scalp-free tissue reconstruction with synthetic mesh cranioplasty. DATA SOURCES: Search strategies created with a medical librarian were implemented using multiple databases in May 2021. REVIEW METHODS: Two reviewers independently performed the review, data extraction, and quality assessment. Cohort studies of patients with scalp-free tissue reconstruction with or without mesh cranioplasty were included. Studies that did not report whether mesh was used or did not separate outcomes by mesh use were excluded. The primary outcomes were free flap failure and postoperative complications. A random-effects model was used for the meta-analysis to estimate prevalence and prevalence ratios (PRs). RESULTS: A total of 28 studies and 440 cases of scalp-free tissue reconstruction were included. The pooled prevalence of free flap failures and postoperative complications in patients with mesh cranioplasty was estimated at 7% (95% confidence interval [CI], 3%-17%; p = .85, I2 = 0%) and 21% (95% CI, 14%-31%; p = .44, I2 = 0%), respectively. In a subgroup analysis, mesh cranioplasty was not associated with a significantly increased risk of free flap failure or postoperative complications when compared to cases without mesh cranioplasty; pooled PR 1.21 (95% CI, 0.50-2.88; p = .90, I2 = 0%) for free flap failure and PR 1.85 (95% CI, 0.89-3.85; p = .28, I2 = 19) for postoperative complications. CONCLUSION: Synthetic mesh cranioplasty does not significantly increase the risk of free flap compromise or postoperative complications. A higher prevalence of postoperative recipient site complications was observed in patients with mesh cranioplasty.

Neighborhood Socioeconomic Status and Racial and Ethnic Survival Disparities in Oral Cavity and Laryngeal Cancer.

BACKGROUND: Oral cavity cancer (OCC) and laryngeal cancer are among the most common cancers worldwide. This study investigated survival in non-Hispanic (NH) Black, NH White, Asian, and Hispanic patients with OCC and laryngeal cancer of low, intermediate, and high neighborhood socioeconomic status (nSES). METHODS: We used data from the SEER 18 Census Tract-level SES and Rurality Database of the National Cancer Institute to create cohorts of OCC and laryngeal cancer patients from 2013 to 2018. Univariate survival analysis was performed with Kaplan-Meier curves and log-rank P values by nSES and then the cross-classification of race, ethnicity, and nSES. We used Cox proportional hazards regression model for multivariable analysis. RESULTS: Higher nSES was associated with better OCC survival for NH White, NH Black, and Asian patients, and better laryngeal cancer survival for NH White, NH Black, Hispanic, and Asian patients. In the multivariable analyses of both OCC and laryngeal cancer survival, NH Black patients had worse survival than NH White patients in the high nSES tertile. NH Black patients with OCC were at higher risk of death than NH White patients at all nSES levels. Conversely, Asian patients with laryngeal cancer demonstrated better survival than other races within the high nSES. CONCLUSIONS: Overall survival differs between racial and ethnic groups of similar nSESs. These health disparities in patients with OCC and laryngeal cancer reflect broader inequities in the cancer control continuum. IMPACT: The cross-classification of race, ethnicity, and nSES revealed disparities in the 5-year overall survival of patients with OCC and laryngeal cancer and highlights the importance of intersectionality in the discussion of health equity.

Characteristics of acute otitis media in primary care are associated with tympanostomy tube outcomes.

Objective: To identify characteristics of acute otitis media (AOM) at primary care presentation associated with TT placement and outcomes. Methods: A retrospective cohort study of pediatric patients (birth-12 years old) with AOM at an academic primary care pediatric practice and affiliated tertiary referral free-standing Children's hospital from August 1, 2017 to December 31, 2019 was performed. The outcomes measured were TT placement, postoperative otorrhea, need for additional tube placement, and other complications (i.e., perforation and/or granulation). Results: The 3189 patients were included, 484 of whom were referred to otolaryngology. Multivariate logistic regression analysis revealed that a greater number of AOM episodes diagnosed at primary care was associated with tube placement (OR = 1.21; 95% CI, 1.04-1.41, p = .02). Of the 336 patients who received tubes, older age at first AOM diagnosis was associated with postoperative otorrhea (OR = 1.02; 95% CI, 1.01-1.03; p = .001) and additional tube placement (OR = 1.03; 95% CI, 1.02-1.04; p < .001). Older age was also associated with other complications (OR = 1.02; 95% CI, 1.01-1.03; p = .001) by univariate analysis. Additionally, postoperative otorrhea was more common among patients who first received an AOM diagnosis at primary care in the spring (OR = 2.69; 95% CI, 1.37-5.29; p = .004), summer (OR = 2.88; 95% CI, 1.46-5.69; p = .002), and fall (OR = 2.18; 95% CI, 1.20-3.96; p = .01) seasons. Conclusions: Clinical data from pediatric primary care visits found older age at first AOM diagnosis and having a first AOM diagnosis outside of winter to be associated with a more complicated eventual disease course. Level of evidence: 3-cohort study.

Urine Drug Screening for Isolated Marijuana Use in Labor and Delivery Units.

Isolated marijuana use is frequently used as an indication for urine drug screening in labor and delivery units. We aimed to identify the results of urine drug screening in a labor and delivery unit for isolated marijuana use. This retrospective cohort study reviewed data from patients admitted for delivery at an urban academic center from January 1, 2020, to December 31, 2020. Patients undergoing urine drug screening for isolated marijuana use were more likely to be younger (median age 25 vs 29 years, P <.001), more often Black (adjusted odds ratio [aOR] 2.58, 95% CI 1.94-3.41), and more likely to have public insurance (aOR 1.54, 95% CI 1.21-1.95). A few (5/338, 1.5%) urine drug screening tests performed for isolated marijuana use were positive for substances besides marijuana. Most patients (177/197, 89.8%) with a urine drug screening test result that was positive for marijuana were reported to the state child abuse hotline. The utility of isolated marijuana use as a criterion for urine drug screening thus appears limited in benefit but rife with inequitable potential to harm.

Ceftriaxone use for acute otitis media: Associated factors in a large U.S. primary care population.

BACKGROUND: Clinicians in the authors' primary care academic practice have anecdotally perceived an increased use of intramuscular (IM) ceftriaxone, particularly for otitis-conjunctivitis in recent years (pre-pandemic). Increasing rates of ceftriaxone administration for acute otitis media (AOM) may be an important marker of antimicrobial resistance. OBJECTIVE: We aimed to characterize the population of patients who received ceftriaxone for treatment of AOM, testing our hypothesis that patients with concomitant conjunctivitis would have increased rates of ceftriaxone receipt. DESIGN/METHODS: We reviewed cases of AOM at a large U.S. primary care practice from August 2017 to July 2019. We determined the association between each of the following variables and ceftriaxone injection using multivariate analysis: age at AOM diagnosis, provider type, insurance (public vs private), season of year, and presence of conjunctivitis. RESULTS: There were 6028 AOM episodes in 5195 patients resulting in a total of 7688 patient encounters. Of these episodes, 642 (10.7%) had a concurrent diagnosis of conjunctivitis; 362 (6.0%) ultimately received ceftriaxone. Conjunctivitis was the strongest predictor of treatment with ceftriaxone. The proportion of episodes with conjunctivitis treated with ceftriaxone was 14.5% (93/642) versus 5.0% (269/5386) without conjunctivitis (p < 0.0001). Patients who received ceftriaxone were younger; mean age (SD) for patients receiving ceftriaxone was 14.0 (8.8) months versus 25.0 (23.4) months (p < 0.0001). CONCLUSION(S): There is a strong correlation between the presence of conjunctivitis and receipt of IM ceftriaxone in this large U.S. academic primary care clinic. Younger age was also associated with ceftriaxone treatment. Further study on emerging resistance patterns and implications for management of AOM in young children is warranted.

Human primary middle ear epithelial cell culture: A novel in vitro model to study otitis media.

OBJECTIVES: Otitis media (OM) is a ubiquitous pediatric disease leading to a significant health care burden. There is no medication beneficial to resolving COM fluid, highlighting the need for research in the field. Crucially, current human middle ear epithelial cell models are transformed cells not recapitulating physiological functions. Herein, we describe a new method to proliferate and differentiate pediatric primary middle ear epithelial cells (pMEEC) from patients as a physiological model for the study of OM. METHODS: We adapted a cell reprogramming protocol using irradiated fibroblast feeder medium in addition to Rho kinase inhibitor to proliferate pMEEC collected during cochlear implant surgery. Cells were plated on transwell membranes, proliferated with conditionally reprogrammed culture medium, and transferred to air-liquid interface (ALI). Cultures were maintained for 4 weeks at ALI, photos were taken and cell lysates and secretions were collected over time for characterization analysis using quantitative polymerase chain reaction, Western bolt, and proteomics. Keratins, MUC5B and MUC5AC mucins, and beta tubulin (TUBB) were analyzed at the mRNA and protein level. RESULTS: Cultures took a mean of 2 weeks to proliferate before transwell plating and forming a tight epithelium at ALI from 2 to 4 weeks. Although mRNA expression of MUC5B, MUC5AC, TUBB, and keratin 5 (KRT5) were variable depending on the differentiation stage and the patient, both TUBB and KRT5 proteins were detected until week 2. CONCLUSION: We demonstrate a novel method to proliferate and differentiate pMEECs that express epithelial markers and that are able to secrete mucins for the study of OM. LEVEL OF EVIDENCE: NA.
