Facial Flap Necrosis From COVID-19 Face Mask Precautions.

ABSTRACT: Use of facial mask coverings has been a strong Centers for Disease Control and Prevention recommendation as an essential mitigation measure in the spread of the SARS-CoV-2 novel coronavirus (COVID)-19 virus. Face mask utilization has been shown to induce changes in the skin microclimate, especially around the perioral and perinasal regions. This results in increased mask adjustments and development of friction between masks and the underlying skin. The authors report novel findings of 2 individuals with skin cancer who underwent facial reconstruction during the COVID-19 pandemic. They encountered untoward sequelae of facial flap pressure necrosis due to the use of face mask coverings. These individuals were ultimately successfully treated with local wound care. One individual experienced auricular implant extrusion and flap loss. It is critical that reconstructive surgeons be aware of potential complications and the need for potential revision surgeries due to the use of face masks, and educate their patients to properly position the protective face masks based on the type of reconstruction performed. Plastic surgeons might also reconsider reconstructive management options in light of these additional obstacles.

Reduction of Myocardial Ischemia-Reperfusion Injury by Inhibiting Interleukin-1 Alpha.

BACKGROUND: Interleukin-1α (IL-1α) released by dying cells is an alarmin that activates the innate immunity. We hypothesized that after myocardial ischemia-reperfusion (I/R) injury, IL-1α amplifies the myocardial damage by activating the inflammasome and caspase-1. METHODS: Adult male CD1 mice were used. The left anterior descending coronary artery was ligated for 30 minutes, after 24 hours of reperfusion. An IL-1α blocking antibody (15 µg/kg intraperitoneally) or matching vehicle was given after reperfusion. A subgroup of mice underwent sham surgery. We assessed the effects of IL-1α blockade on caspase-1 activity, infarct size, cardiac troponin I serum levels, and left ventricular fractional shortening, 24 hours after I/R. RESULTS: I/R led to inflammasome formation, and IL-1α blockade significantly reduced inflammasome formation, reflected by a >50% reduction in caspase-1 activity versus vehicle (P = 0.03). IL-1α blockade also reduced the infarct size (-52% infarct expressed as percentage of area at risk, and -79% for cardiac troponin I serum levels, P < 0.001 vs. vehicle) and preserved the left ventricular fractional shortening (31 ± 3% vs. 25 ± 2%, P < 0.001 vs. vehicle). CONCLUSION: IL-1α blockade after I/R reduces the inflammasome activation, decreases the infarct size, and preserves the left ventricular function. IL-1α blockade may therefore represent a novel therapeutic strategy to reduce I/R injury.

Perceptions of Racial and Gender Microaggressions in an Academic Orthopaedic Department.

Orthopaedic surgery consistently ranks last among all medical specialties in diversity and inclusion. While active efforts have recently been implemented to enact change, no study to date has explored the potential effects that social microaggressions have on an individual's career in orthopaedic surgery. The primary aim of this study was to investigate the influence of the perceived experiences of gender and race-based microaggressions on orthopaedic surgery residents, fellows, and attendings in their decision to pursue a career in orthopaedic surgery. Methods: A 34-question institutional review board-approved, modified version of the validated Racial and Ethnic Minorities Scale and Daily Life Experiences survey was sent to a total of 84 individuals at the University of Miami (UM) Department of Orthopaedics. Responses were anonymously collected from current UM orthopaedic residents, fellows, and attendings. Survey results were analyzed for the prevalence of microaggressions in the context of sex, race, ethnicity, academic goals, daily scenarios, and department support. p-Values less than 0.05 were considered statistically significant. Results: Fifty-four of 84 respondents (64%) completed the survey. Female respondents experienced significantly more gender-based microaggressions than male respondents. On average, male participants disagreed that their experiences with microaggressions made them doubt their ability to pursue a career in orthopaedic surgery while female participants responded they were neutral. In comparison with their White counterparts, non-White and Hispanic ethnicity participants demonstrated a statistically significantly greater frequency of race and ethnicity-based microaggressions. Conclusion: Our study demonstrates that female participants, non-White participants, and Hispanic minorities across all levels of training experience a higher frequency of microaggressions. The impact of these experiences on career decisions and goals for women and persons of color in orthopaedic surgery at this single institution is mixed. Experienced microaggressions should be further investigated as a potential barrier to recruitment and retention of under-represented minorities in orthopaedic surgery. Level of Evidence: III.

Racial and ethnic minorities in lower income brackets are associated with late-stage diagnosis of non-ocular melanoma.

INTRODUCTION: Despite advances in oncologic care, racial and socio-economic outcome disparities persist in non-ocular melanoma patients. However, the unmet need is understanding the population at risk for late tumor stage at diagnosis. We sought to analyze the groups with an increased risk of unfavorable tumor stage at diagnosis. METHODS: Patients with non-ocular melanoma were reviewed using the 2000-2019 SEER Research Data (SEER*Stat) and grouped into early tumor stage at diagnosis (stage I-IIC) and late (stage III-IVC). Multivariable logistic and Cox regression examined the association of demographic, socioeconomic, and clinical factors with late-stage diagnosis and overall survival, respectively. Kaplan-Meier estimates were calculated with racial and county-level household income stratification to evaluate overall survival differences. RESULTS: Of 147,606 patients diagnosed with non-ocular melanoma, 38,695 cases were identified based on inclusion and exclusion criteria and separated into those with early-stage diagnosis (median 63 years) and those with late-stage (median 62 years). Male gender, Black race, Asian or Pacific Islander race, and Hispanic ethnicity were significantly associated with late-stage tumor diagnosis (p < 0.001). Receipt of surgery and a median county-level household income >$75,000 were protective for late-stage tumor diagnosis (p < 0.001). Additionally, male gender, Black, Asian or Pacific Islander, American Indian/Alaskan Native races, metastasis, and late-stage diagnosis were associated with factors significantly associated with decreased overall survival (p-value <0.001). Receipt of surgery and a median household income of $50,000-$74,999 and >$75,000 were factors associated with increased overall survival (p < 0.001). The median overall survival was 89 months, but Black patients (58 months) and <$50,000 income households (75 months) had significantly worse survival (p < 0.001). CONCLUSIONS: Hispanic ethnicity, Black and Asian or Pacific Islander race, and low-income households were associated with late-stage non-ocular melanoma at diagnosis. Black, Asian or Pacific Islander and American Indian/Alaskan Native races and lower-income households were associated with worse overall survival. Identifying addressable causal factors that link this at-risk population to poor cancer prognosis is warranted.
