Abstract Purpose Medical school tuition has increased at alarming rates ahead of inflation over the past 20 years. The authors investigated whether state-funded medical schools have had an increased number of out-of-state matriculants, which may create a diaspora of displaced in-state medical students matriculating to out-of-state programs and incurring substantial debt. Method Publicly available data from the Association of American Medical Colleges (AAMC) were accessed from 2004 through 2019 for applicants and matriculants at U.S. state-funded schools. Schools listed as public that reported tuition charges in the AAMC Tuition and Student Fees reports were included in this study. The numbers and trends of medical school applications and trends in tuition costs and average indebtedness were summarized for in-state and out-of-state matriculants. Values were analyzed by group as median and interquartile range (IQR). Group differences were assessed via t tests. P values less than .05 were considered statistically significant. Results From 2004 through 2019, the annual number of out-of-state matriculants in state-funded schools increased 7% (16%–23% [7,195–11,144]). Among 74 schools with data in 2004, the median percentage of out-of-state applications increased from 60% (IQR, 31%–74%) to 80% (IQR, 57%–85%; P < .001), and the median percentage of out-of-state matriculants increased from 13% (IQR, 5%–23%) to 17% (IQR, 11%–33%; P < .001). In 2004, the mean (standard error) debt upon completion of medical school (inflation adjusted to 2018 dollars) was $144,100 ($10,950); by 2016, the mean debt had increased to $251,600 ($32,040), a 75% increase over 12 years. Conclusions Since 2004, substantial increases have occurred in out-of-state matriculants at state-funded medical schools. This may displace residents from attending their in-state schools, causing them to attend out-of-state or private medical schools, where tuition is typically much higher.

Background Diagnosis of non-esophageal eosinophilic gastrointestinal disorders requires quantification of tissue eosinophils. Our objective was to evaluate eosinophil peroxidase (EPX) immunohistochemistry (IHC) as a method for histologic diagnosis of eosinophilic gastritis (EG) and eosinophilic duodenitis (EoD). Methods We performed a retrospective analysis of biopsies from pediatric EG/EoD cases and controls. Subjects with EG or EoD had ≥30 eosinophils per high power field (eos/hpf) in ≥5 hpf in the stomach and/or ≥3 hpf in the duodenum, respectively. Controls had no histopathologic diagnosis recorded. Tissue eosinophil counts were assessed by hematoxylin & eosin stains. EPX stains were assessed using a unique histopathologic scoring system. Slides were digitized and EPX+ staining area/mm 2 was quantified by image analysis. Results Twenty-six EG/EoD cases and 40 controls were analyzed. EPX scores and EPX/mm 2 levels were markedly elevated in EG/EoD (p ≤ 0.0001). Eosinophil density (eos/mm 2 ) correlated strongly with EPX scores and EPX/mm 2 levels in the stomach (r ≥ 0.77) and moderately with EPX scores and EPX/mm 2 levels in the duodenum (r ≥ 0.52); (p < 0.0001). EPX quantification identified EG/EoD subjects with high diagnostic accuracy (EPX score: AUC = 1 for EG and EoD; EPX/mm 2 : AUC = 0.98 (95%CI 0.96-1) for EG, AUC = 0.91 (95%CI 0.81-1) for EoD). Conclusion EPX-based assessment of eosinophilic inflammation may facilitate automated histologic diagnosis.

The clinical significance of valves within gonadal veins is controversial. In males, the absence of valves in the left testicular vein (compared to the right) has been cited as a potential mechanism for varicocele formation in the pampiniform plexus in the scrotum. In females, ovarian vein valve absence or incompetence may lead to pelvic congestion syndrome, a disputed explanation for pelvic, abdominal, and/or flank pain of unknown etiology. One study suggests that females have incompetent valves in dilated veins more frequently than males due to past pregnancies. Furthermore, inconsistencies exist in the reported incidence of gonadal vein valves, though pelvic insufficiency is more thoroughly documented and diagnosed in males than in females. This study assesses the presence, number, and location of gonadal vein valves in male and females. The right and left gonadal veins were evaluated in 13 embalmed cadavers (7 males, 6 females; mean age = 86.3 +/− 6.2 years). Twenty‐four veins were available for dissection; two veins were lost to dissection and therefore omitted. The veins were dissected from the ovary (females) or deep inguinal ring (males) to the point of drainage into the inferior vena cava (right gonadal vein) or left renal vein (left gonadal vein). The veins were incised along the entire length of this course, and the number and location of valves was noted and photographed. Anatomical variation and pathological dilation in the vasculature was also documented. A total of 8 valves were found among the 24 dissections. Valves were present in four of the six females (67%) compared to one out of seven males (14%). The valve in the male was located in the left gonadal vein; the bilateral distribution in females was more randomly patterned. The majority of the valves (87.5%) in females were located distally, adjacent to the ovary, while a single valve was located adjacent to the left renal vein confluence. No dilation was noted in any of the specimens. The male population in this study had a lower incidence of gonadal vein valves than in previous studies. However, the number of valves in female gonadal veins was considerably greater than in males. This finding has not been reported previously, perhaps due to the emphasis on male pelvic congestion as a risk for infertility versus attributing the condition in females to a psychosomatic etiology. The primary limitation of this research is the small sample size. Future work will explore the clinical implications of these preliminary findings in a patient population. Clinical correlation with patients who are suspected or known to suffer from pelvic congestion syndrome may shed further light on the role of gonadal vein valves in vein sufficiency and inform more effective treatment for this poorly understood condition in the female patient population.
