A Pilot Needs Assessment Addressing Gender-Based Microaggressions in Surgical Trainees.

BACKGROUND: Microaggressions result in the unintentional discrimination of marginalized groups. Female trainees are underrepresented in all levels of surgical training, thus, microaggressions are a salient topic for surgical education. This study aims to explore the perceived effect of gender-based microaggressions on surgical trainees. METHODS: After IRB approval, an anonymous Likert-scaled survey on perceptions of microaggressions was distributed to interns at our institution prior to starting surgical residency and one year after. Data was de-identified and analyzed using Likert analysis and Mann-Whitney U testing. Follow-up focus groups were lead and transcriptions analyzed using detailed thematic analysis. RESULTS: Sixty-nine of 104 interns (66%) responded to the initial survey, 34 (49%) were female. Nineteen of 38 interns (50%) responded to the follow-up survey, 10 (53%) were female. Compared to male repondents, females were significantly more likely to believe they were likely to experience microaggressions (median = 5, IQR 4-5 vs median = 4, IQR 3-4, p < 0.0001) and that microaggressions would impact their mental health (median = 4, IQR 4-4 vs median = 3, IQR 2-4, p < 0.0002). One-year follow-up data similarly revealed that, compared to male respondents, females were significantly more likely to have experienced microaggressions on a frequent basis throughout intern year (median = 3, IQR 3-3.75 vs median = 1.5, IQR 1-3, p < 0.05) and to have subjectively felt the impact of microaggressions on their mental health (median = 3, IQR 2.25-4 vs median = 1.5, IQR 1-2.25, p < 0.05). A focus group of female surgical trainees demonstrated patterns consistent with previously validated themes on gender-based microaggressions, including environmental invalidations, being treated as a second class citizen, and assumption of inferiority, at all levels of training. CONCLUSIONS: New trainees experience anxiety and lack preparedness when confronted with the threat of microaggressions. Our study reveals that female surgical interns are more likely than males to worry about microaggressions and to experience microaggressions and their negative effects. Focus group data exposes the wide-ranging impact of microaggressions experienced by female trainees of all levels. Thus, there should be benefit from instituting formal microaggression training prior to starting surgical residency.

Silicone Breast Implant Surface Texture Impacts Gene Expression in Periprosthetic Fibrous Capsules.

BACKGROUND: Silicone breast implants with smooth outer shells are associated with higher rates of capsular contracture, whereas textured implants have been linked to the development of breast implant-associated anaplastic large cell lymphoma. By assessing the gene expression profile of fibrous capsules formed in response to smooth and textured implants, insight into the development of breast implant-associated abnormalities can be gained. METHODS: Miniature smooth or textured silicone implants were surgically inserted into female rats ( n = 10) and harvested for the surrounding capsules at postoperative week 6. RNA sequencing and quantitative polymerase chain reaction were performed to identify genes differentially expressed between smooth and textured capsules. For clinical correlation, the expression of candidate genes was assayed in implant capsules harvested from human patients with and without capsular contracture. RESULTS: Of 18,555 differentially expressed transcripts identified, three candidate genes were selected: matrix metalloproteinase-3 ( MMP3 ), troponin-T3 ( TNNT3 ), and neuregulin-1 ( NRG1 ). In textured capsules, relative gene expression and immunostaining of MMP3 and TNNT3 was up-regulated, whereas NRG1 was down-regulated compared to smooth capsules [mean relative fold change, 8.79 ( P = 0.0059), 4.81 ( P = 0.0056), and 0.40 ( P < 0.0001), respectively]. Immunostaining of human specimens with capsular contracture revealed similar gene expression patterns to those of animal-derived smooth capsules. CONCLUSIONS: An expression pattern of low MMP3 /low TNNT3 /high NRG1 is specifically associated with smooth implant capsules and human implant capsules with capsular contracture. The authors' clinically relevant breast implant rat model provides a strong foundation to further explore the molecular genetics of implant texture and its effect on breast implant-associated abnormalities. CLINICAL RELEVANCE STATEMENT: The authors have demonstrated that there are distinct gene expression profiles in response to smooth versus textured breast implants. Since surface texture may be linked to implant-related pathology, further molecular analysis of periprosthetic capsules may yield strategies to mitigate implant-related complications.

Challenging the Norm: Is Routine Use of Cranial CT in Evaluation of Craniosynostosis Necessary?

BACKGROUND: Cranial CT is routinely taught to be the gold standard for diagnosis of craniosynostosis and used by craniofacial teams for suspected nonsyndromic single suture craniosynostosis. Given the risks associated with infant CTs, do these scans provide significantly enhanced diagnostic accuracy compared to the physical exam when performed by an experienced clinical provider? METHOD: A retrospective chart review was performed for children who underwent corrective surgery for nonsyndromic, single-suture craniosynostosis over an 11 year period by a single craniofacial team. Ages at presentation and surgery, preoperative clinical diagnosis and imaging, co-existing radiographic findings, and correlation with the intraoperative diagnosis were analyzed. RESULTS: A total of 138 patients were included in this study. The mean age was 4.2 months at initial craniofacial evaluation, and 8.0 months at time of surgery. Twenty-seven patients received imaging prior to our clinic. Of those, 21 had plain radiography and 6 had CT scans. Of the remaining 111 patients referred without imaging, craniosynostosis was clinically diagnosed in 102 (92%), whereas 9 (8%) had an unclear clinical diagnosis. Of these 9, 1 (1%) was diagnosed clinically at follow-up exam, and the remaining 8 (7%) were diagnosed using radiography (3 CT scans, 5 plain radiographs). In all patients, the preoperative diagnosis was confirmed during intraoperative assessment. CONCLUSIONS: Cranial CT was not needed by experienced craniofacial providers in 93% of nonsyndromic, single-suture craniosynostosis. Imaging obtained before craniofacial clinic referral may have been unnecessary. These findings question the classic teaching that preoperative cranial CT is the gold standard for diagnosis in infants with nonsyndromic, single-suture craniosynostosis.

Cutaneous Manifestations of COVID-19: An Evidence-Based Review.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has affected 18 million people and killed over 690,000 patients. Although this virus primarily causes respiratory symptoms, an increasing number of cutaneous manifestations associated with this disease have been reported. OBJECTIVE: The aim of this review was to collate and categorize the dermatologic findings reported in patients with COVID-19 and identify specific lesions that may facilitate diagnosis and prognostication. METHODS: An evidence-based review of the PubMed database was conducted on 14 May, 2020 using the search terms "Covid-19 skin," "Covid-19 rash," "Covid-19 exanthem," and "Covid-19 chilblains." Peer-reviewed publications containing original COVID-19 patient cases and a discussion of the associated cutaneous findings were included in the analysis. RESULTS: The literature search identified 115 records, of which 34 publications describing 996 patients with dermatologic conditions were included. Case reports (n = 15), case series (n = 13), and observational prospective studies (n = 4) were the most common publication types. Acral lesions resembling pseudo-chilblains were the most frequent lesion identified (40.4% of cases), appearing in young adults (mean age, 23.2 years) after the onset of extracutaneous COVID-19 symptoms (55/100 patients). Erythematous maculopapular rashes affected 21.3% of patients, most frequently impacting middle-aged adults (mean age, 53.2 years) and occurring at the same time as non-cutaneous symptoms (110/187 patients). Vesicular rashes affected 13.0% of patients, appearing in middle-aged adults (mean age, 48.3 years) after the onset of other symptoms (52/84 patients). Urticarial rashes affected 10.9% of patients, appearing in adults (mean age, 38.3 years) and occurring at the same time as non-cutaneous symptoms (46/78 patients). Vascular rashes resembling livedo or purpura were uncommon (4% of cases), appearing in elderly patients (mean age, 77.5 years) and occurring at the same time as non-cutaneous COVID-19 symptoms (18/29 patients). Erythema multiforme-like eruptions, although infrequent (3.7% of cases), affected mostly children (mean age, 12.2 years). CONCLUSIONS: Vesicular rashes may suggest an initial diagnosis of COVID-19, acral lesions may be most appropriate for epidemiological uses, and vascular rashes may be a useful prognostic marker for severe disease. As a potential correlate to disease severity, prognosis, or infectibility, it is critical that all healthcare professionals be well versed in these increasingly common cutaneous manifestations of COVID-19.

Analysis of Trends in the Selection and Production of U.S. Academic Plastic Surgery Faculty.

In academic plastic surgery, there is a paucity of data examining the relationship between program rank, faculty training history, and production of academic program graduates. The purpose of this study is to determine objective faculty characteristics that are associated with a high program reputation. METHODS: Accreditation Council for Graduate Medical Education-accredited integrated Plastic and Reconstructive Surgery (PRS) programs were ranked using Doximity and divided into Top-quartile programs and Other programs. Accredited medical schools were ranked using U.S. News and World Report. Individual faculty profiles were reviewed on program websites for information on prior training. RESULTS: Seventy-nine programs with 712 faculty were identified and objectively analyzed. Compared to Other PRS programs, Top-quartile programs had a higher proportion of faculty that trained at Top-quartile residency programs (P < 0.0001) and Top-quartile medical schools (P < 0.0001). Top-quartile programs also had the highest proportion of faculty that trained at the same institution for fellowship (P = 0.0001), residency (P = 0.03), medical school (P = 0.4), or any prior training (medical school, residency, or fellowship) (P = 0.002). Top-quartile programs were associated with the largest total faculty size (P < 0.0001) and the largest number of graduates entering the field of academic plastic surgery (P < 0.0001). CONCLUSIONS: Program reputation is associated with PRS faculty selection and production. Top-ranked programs are more likely to have faculty that previously trained at the same institution or at top-ranked programs. Top-ranked programs are more likely to graduate residents that will become academic plastic surgeons.

Prevention of postsurgical lymphedema via immediate delivery of sustained-release 9-cis retinoic acid to the lymphedenectomy site.

BACKGROUND AND OBJECTIVES: Previously, we have shown that 9-cis retinoic acid (9-cis RA) stimulates lymphangiogenesis and limits postsurgical lymphedema in animal models when administered via daily intraperitoneal injections. In this study, we investigate whether a single-use depot 9-cis RA drug delivery system (DDS) implanted at the site of lymphatic injury can mitigate the development of lymphedema in a clinically relevant mouse limb model. METHODS: Hind limb lymphedema was induced via surgical lymphadenectomy and irradiation. Animals were divided into two treatment groups: (1) 9-cis RA DDS, (2) placebo DDS. Outcomes measured included paw thickness, lymphatic clearance and density, epidermal thickness, and collagen deposition. RESULTS: Compared with control animals, 9-cis RA-treated animals had significantly less paw swelling from postoperative week 3 (P = .04) until the final timepoint at week 6 (P = .0007). Moreover, 9-cis RA-treated animals had significantly faster lymphatic clearance (P < .05), increased lymphatic density (P = .04), reduced lymphatic vessel size (P = .02), reduced epidermal hyperplasia (P = .04), and reduced collagen staining (P = .10). CONCLUSIONS: Animals receiving 9-cis RA sustained-release implants at the time of surgery had improved lymphatic function and structure, indicating reduced lymphedema progression. Thus, we demonstrate that 9-cis RA contained within a single-use depot DDS has favorable properties in limiting pathologic responses to lymphatic injury and may be an effective strategy against secondary lymphedema.

A Pre-clinical Animal Model of Secondary Head and Neck Lymphedema.

Head and neck lymphedema (HNL) is a disfiguring disease affecting over 90% of patients treated for head and neck cancer. Animal models of lymphedema are used to test pharmacologic and microsurgical therapies; however, no animal model for HNL is described in the literature to date. In this study we describe the first reproducible rat model for HNL. Animals were subjected to two surgical protocols: (1) lymphadenectomy plus irradiation; and (2) sham surgery and no irradiation. Head and neck expansion was measured on post-operative days 15, 30 and 60. Magnetic resonance imaging (MRI) was acquired at the same time points. Lymphatic drainage was measured at day 60 via indocyanine green (ICG) lymphography, after which animals were sacrificed for histological analysis. Postsurgical lymphedema was observed 100% of the time. Compared to sham-operated animals, lymphadenectomy animals experienced significantly more head and neck swelling at all timepoints (P < 0.01). Lymphadenectomy animals had significantly slower lymphatic drainage for 6 days post-ICG injection (P < 0.05). Histological analysis of lymphadenectomy animals revealed 83% greater subcutis thickness (P = 0.008), 22% greater collagen deposition (P = 0.001), 110% greater TGFß1+ cell density (P = 0.04), 1.7-fold increase in TGFß1 mRNA expression (P = 0.03), and 114% greater T-cell infiltration (P = 0.005) compared to sham-operated animals. In conclusion, animals subjected to complete lymph node dissection and irradiation developed changes consistent with human clinical postsurgical HNL. This was evidenced by significant increase in all head and neck measurements, slower lymphatic drainage, subcutaneous tissue expansion, increased fibrosis, and increased inflammation compared to sham-operated animals.

Analysis of the Microsurgery Match from 2014 to 2018 Reveals Increased Competition for Microsurgery Fellowship Positions.

BACKGROUND: There has been no peer-reviewed published data analyzing the microsurgery match since it was established. The aim of this study is to present and analyze match data to inform residents and programs regarding outcomes. METHODS: Anonymized data were requested from the San Francisco Match, which was plotted and analyzed utilizing Pearson's Chi-square, unpaired t-test, and one-way analysis of variance (ANOVA). RESULTS: Match data was obtained from the years 2014 to 2018. The match rate decreased from 84.6% in 2015 to 67.3% in 2018, mean = 73.7 (8.29%), and (p = 0.01735). The position fill rate fluctuated from 82.9% in 2014 to 90.0% in 2016, mean = 86.5 (3.0%). In 2014 and 2015, 66.7% of applicants matched their first or second choice compared to 48.0% in 2018, mean = 58.7 (8.3%), (p =.04785). Matched applicants ranked mean = 6.6 (1.4%) programs versus 3.4 (1.3) for unmatched, (p < 0.0001). Filled programs ranked a greater number of applicants per position, mean = 8.5 (1.8%), compared to partially filled, mean = 4.6 (2.6%), and unfilled mean = 3.6 (3.4%), programs (p = 0.0014). In 2015, 55.0% of programs matched their first or second choice compared to 30.4% of programs in 2018, mean = 43.0 (10.1%). CONCLUSION: The application process for microsurgery has become more competitive. Matched applicants rank more programs than do unmatched. Fully filled programs rank more applicants per position than do unfilled or partially filled. Applicants and programs are increasingly less likely to match their top choices.

Reporting Practices on Immunosuppression and Rejection Management in Face Transplantation: A Systematic Review.

BACKGROUND: Face transplantation is a demanding operation requiring complex planning and expert technical performance. While the documentation of successes of the first transplants is impressive, there are lacunae in reporting of institutional protocols for other critical operation components, namely, immunosuppression, graft surveillance, and management of rejection and graft failure. The purpose of this review is to assess protocol reporting by face transplant teams to determine where we, as a plastic surgery community, can improve. METHODS: A systematic review of PubMed was conducted to identify literature on face transplants published from November, 2005, starting with the first successful transplant to December, 2018. English-language articles were reviewed for reporting of protocols on antimicrobial prophylaxis, immunosuppression, graft surveillance, and management of rejection and graft failure. RESULTS: A total of 44 face transplantation patients were identified. Protocols for antimicrobial prophylaxis, immunosuppressive induction, and maintenance immunosuppression were reported for 61%, 75%, and 73% of patients, respectively. Protocols for graft surveillance and medical management of rejection were reported for 70% of patients in both cases. Surgical salvage strategies to manage graft failure were documented for 43% of patients. CONCLUSION: The current literature on face transplantation does not include consistent reporting on critical aspects of patient care. Medical protocols outlining guidelines for immunosuppression, graft surveillance, and management of rejection and graft failure are the most critical factors determining overall transplant success. However, they are underreported in the literature. Development and communication of standardized protocols is essential to improve patient outcomes and maximize the results of this procedure.

A Chemopreventive Nanodiamond Platform for Oral Cancer Treatment.

Standard oral cancer therapy generally includes a combination of surgery with chemotherapy and/or radiotherapy. This treatment paradigm has not changed in some time. In this paper, we propose a chemopreventive nanodiamond platform for the delivery of celecoxib (Celebrex) to oral cancer lesions. This innovative platform allows for sustained drug release under physiological conditions, potentially enhancing chemopreventive efficacy of celecoxib without the physical and toxicological damage associated with conventional means of drug delivery.
