Scar Perception: A Comparison of African American and White Self-identified Patients.

Scars can have significant morbidity and negatively impact psychological, functional, and cosmetic outcomes as well as the overall quality-of-life, especially among ethnic minorities. The objective of this study was to evaluate African American and White patients' perception of their scars' impact on symptoms, appearance, psychosocial health, career, and sexual well-being, using validated assessment tools. Method: A total of 675 abdominoplasty and breast surgery patients from four providers completed the SCAR-Q, and Career/Sexual Well-Being scales via phone or email. A higher score on both assessments indicates a more positive patient perception. Results: Of the 675 respondents, 77.0% were White, and 23.0% were African American. White patients scored significantly higher on the SCAR-Q (232 ± 79 versus 203 ± 116), appearance (66 ± 26 versus 55 ± 29), and Career/Sexual Well-Being (16 ± 2 versus 15 ± 5) scales than African American patients (P < 0.001, P < 0.001, P < 0.001, respectively). There was no significant correlation between duration after surgery and symptoms or appearance scores for African American patients (P = 0.11, P = 0.37). There was no significant correlation between patient age and SCAR-Q score or time after surgery and psychosocial scores. Conclusions: African American patients are more likely to have lower perceptions of their scarring appearance, symptoms, psychosocial impact, career impact, and sexual well-being impact than White patients. Scar appearance and symptoms are less likely to improve over time for African American patients. This study highlights the need to address patient ethnicity when considering further follow-up, counseling, or other measures to enhance scar perception.

Representation of African American Patients in Social Media for Breast Reconstruction.

BACKGROUND: Social media use by plastic surgeons may contribute to the overall increase in breast reconstruction in the United States. However, recent data show a concerning decrease in breast reconstruction in African American women. The purpose of this study was to analyze the inclusion of African American women in social media posts for breast reconstruction, with the premise that this may be a possible contributing factor to decreasing rates of breast reconstruction in this population. METHODS: Data from several social media platforms were obtained manually on December 1, 2019. Each image was analyzed using the Fitzpatrick scale as a guide. RESULTS: A total of 2580 photographs were included that met the authors' criteria. Only 172 photographs (6.7 percent) were nonwhite. This study surveyed 543 surgeons, 5 percent of whom were nonwhite. The analysis of the results from the random sample of the top plastic surgery social media influencers showed that only 22 (5 percent) of the photographs uploaded were nonwhite patients. Furthermore, 30 percent of surgeons did not have any photographs of nonwhite patients uploaded. CONCLUSIONS: Numerous factors can contribute to the disparity between the growing trend of white patients seeking reconstructive surgery compared to the decreasing trend of African American patients, one of which may be the disparity in their representation in social media, particularly among common platforms and social media influencers. This study highlights the evolving factors that may impair African American breast cancer patients' access to safe, effective breast reconstruction, which must be identified and resolved.

Local Perturbations of Cortical Excitability Propagate Differentially Through Large-Scale Functional Networks.

Electrophysiological recordings have established that GABAergic interneurons regulate excitability, plasticity, and computational function within local neural circuits. Importantly, GABAergic inhibition is focally disrupted around sites of brain injury. However, it remains unclear whether focal imbalances in inhibition/excitation lead to widespread changes in brain activity. Here, we test the hypothesis that focal perturbations in excitability disrupt large-scale brain network dynamics. We used viral chemogenetics in mice to reversibly manipulate parvalbumin interneuron (PV-IN) activity levels in whisker barrel somatosensory cortex. We then assessed how this imbalance affects cortical network activity in awake mice using wide-field optical neuroimaging of pyramidal neuron GCaMP dynamics as well as local field potential recordings. We report 1) that local changes in excitability can cause remote, network-wide effects, 2) that these effects propagate differentially through intra- and interhemispheric connections, and 3) that chemogenetic constructs can induce plasticity in cortical excitability and functional connectivity. These findings may help to explain how focal activity changes following injury lead to widespread network dysfunction.
