Assessing the Prevalence of Microaggressions in Plastic Surgery Training: A National Survey.

There has been increased awareness of microaggressions occurring during medical training. However, the prevalence and characteristics of microaggressions specifically in plastic surgery residency remain unknown. We aimed to fill this literature gap by conducting a nationwide survey to better understand and characterize microaggressions in plastic surgery training. METHODS: A survey was distributed between March and May 2021 via the American Society of Plastic Surgeons Resident Representatives to 1014 integrated and 214 independent track plastic surgery trainees in the United States. Multiple Pearson's chi-square of independence and Fisher exact tests evaluated comparisons of microaggressions by sex, race, Hispanic origin, sexual orientation, and year in training. A multivariate regression analysis assessed associations between variables. RESULTS: One hundred twenty-five participants responded to the survey (response rate: 10.2%). Of those who responded, 68.8% had experienced microaggressions in the past year. Female trainees experienced microaggressions more frequently than male trainees (P < 0.05). Asian trainees had higher odds to be a target of microaggressions compared with White trainees (P = 0.013). Nonheterosexual trainees were more likely to have experienced microaggressions compared with heterosexual trainees (P < 0.05). Independent trainees were more likely to experience microaggressions than PGY 1-2 and 3-4 integrated residents (P < 0.05). CONCLUSIONS: Approximately seven in every 10 trainees stated that they experienced microaggressions in the past year. Females, racial minorities, sexual minorities, and independent trainees had higher odds of reporting that they experienced microaggressions. Further studies are needed to assess the implementation of strategies that address this problem to resolve inequities.

Chitosan as a Bone Scaffold Biomaterial.

The current standard of care for bone reconstruction, whether secondary to injury, nonunion, cancer resection, or idiopathic bone loss, is autologous bone grafting. Alternatives to autograft and allograft bone substitutes currently being researched are synthetic and natural graft materials that are able to guide bone regeneration. One promising material currently being researched is chitosan, a highly versatile, naturally occurring polysaccharide, derived from the exoskeleton of arthropods that is comprised of glucosamine and N-acetylglucosamine. Research on chitosan as a bone scaffold has been promising. Chitosan is efficacious in bone regeneration due to its lack of immunogenicity, its biodegradability, and its physiologic features. Chitosan combined with growth factors and/or other scaffold materials has proven to be an effective alternative to autologous bone grafts. Additionally, current studies have shown that it can provide the additional benefit of a local drug delivery system. As research in the area of bone scaffolding continues to grow, further clinical research on chitosan in conjunction with growth factors, proteins, and alloplastic materials will likely be at the forefront.
