RESUMO
Orthopaedic surgery is well recognized as one of the most competitive and least diverse medical specialties. Despite efforts toward improving diversity, studies have shown that gender and racial/ethnic disparities continue to persist in orthopaedic graduate medical education. Therefore, we sought to identify the match rates of traditionally under-represented groups within orthopaedic surgery-female candidates, racial and ethnic minorities under-represented in medicine (URiM), and osteopathic physicians-compared with their application rates. Methods: A retrospective review of the Electronic Residency Application Service (ERAS) application data from the 2017 to 2021 application cycles was performed, and the total number of applicants, sex, race/ethnicity, and degree type of all students applying for orthopaedic surgery were recorded. A separate database, the Orthopaedic Residency Information Network (ORIN), which is a database self-reported by residency programs to provide information to applicants, was also queried to identify the total number of residents, sex, race/ethnicity, and degree type of all current residents in June 2022, corresponding to those residents who matched in 2017 to 2021. Results: From the ERAS application data, a total of 7,903 applicants applied to orthopaedic surgery during the study period. A total of 1,448 applicants (18%) were female, 1,307 (18%) were URiM, and 1,022 (15%) were from an osteopathic medical school. Based on the ORIN database, 688 of 3,574 residents (19%) were female, 1,131 of 7,374 (19%) were URiM, and 1,022 of US medical school graduates (12%) had a DO degree. The application and match rates were not significantly different for female (p = 0.249) and URiM (0.187) applicants; however, there was a significant difference in the application and match rates (15% vs 12%; p = 0.035) for US medical graduates with a DO degree. Conclusion: In recent years, there has been a significant and necessary push to increase diversity in the field of orthopaedic surgery. From 2017 to 2021, match rates of female and URiM candidates are reflective of their application rates. Osteopathic applicants in orthopaedic surgery have a lower match rate than their allopathic counterparts. Level of Evidence: III.
RESUMO
Within this work, we present the first true three-dimensional (3D) analysis of chondrule size. Knowledge about the physical properties of chondrules is important for validating astrophysical theories concerning chondrule formation and their aggregation into the chondritic meteorites (known as chondrites) that contain them. The classification of chondrites into chemical groups also relies on chondrule properties, including their dimensions. Within this work, we quantify the diameters of chondrules in five ordinary chondrites (OCs; comprised of the H, L, and LL chondrites) and one low-iron enstatite (EL) chondrite. To extract the chondrule size data, we use x-ray computed microtomography to image small (~1-2 cm3 ) chondrite samples followed by manual digital segmentation to isolate chondrules within the volumes or subvolumes. Our data yield true 3D results without stereographic corrections necessary for two-dimensional (2D) or petrographic thin section-based determinations of chondrule sizes. Our results are completely novel, but are consistent with previous surface analysis (2D) data for OCs. Within our OC chondrule diameter data, we find the trend of mean chondrule diameters increasing in the order H < L < LL. We also present the first detailed EL chondrite chondrule size-frequency distribution. Finally, we examine the shapes and collective orientations of the chondrules within the chondrites and show that chondrite petrofabrics can be explored with our methodology. Chondrule shape-preferred orientations are identical to the orientations of the metal and sulfide grains in the chondrites and this is likely due to impact-related compaction. HIGHLIGHTS: We present a first true three-dimensional analysis of chondrule size. Our ordinary chondrite chondrule diameter data demonstrate the trend of mean chondrule diameters increasing in the order H chondrites < L chondrites < LL chondrites. We also present the first detailed low-iron enstatite chondrite chondrule size-frequency distribution. We examine the shapes and collective orientations of the chondrules and show that chondrite petrofabrics can be explored with our methodology.
