Laser Light Therapy in Inflammatory, Musculoskeletal, and Autoimmune Disease.

PURPOSE OF REVIEW: The goal of this review is to summarize the field to date and to discuss strengths and limitations of low-level laser (light) therapy (LLLT) for the future investigation as a treatment of inflammatory disease. RECENT FINDINGS: LLLT is a promising therapeutic, particularly for those diseases of skin and joints because they are most accessible to treatment. Indeed, the known mechanisms of LLLT support its use for anti-inflammatory purposes, as well as stimulation of tissue growth and repair. Although the standard of care for the majority of inflammatory diseases is immunosuppressive agents such as corticosteroids with undesirable toxicities, LLLT offers a unique approach by being non-invasive and incurring minimal side effects. It is also relatively inexpensive and accessible and even has the possibility to be patient directed at home. There is evidence that LLLT is able to modulate the immune system at the skin and joint, and it has been shown to be efficacious in humans by affecting bacterial colonization as it may pertain to chronic rhinosinusitis. However, there is variability in the methods of laser application as well as a lack of evidence for laser type, dose-ranging studies, and wavelength selection that create barriers to the implementation of LLLT without further more rigorous and standardized study. The heterogeneity makes it difficult to draw strong conclusions about the efficacy of LLLT and its mechanisms.

Defining Predictors of Future Academic Productivity in Plastic Surgery Residency.

Background: Research is a valued component of applications to plastic surgery residency. No prior studies have explored factors associated with increased resident research productivity. This study aims to compare the academic productivity levels of plastic surgery residency graduates based on their pre- and postresidency experiences. Methods: Residents graduating in 2019 and 2020 were identified from integrated programs. Metrics collected included the number of publications in medical school and residency. Descriptive statistics were completed along with linear regressions to evaluate the impact of these on academic productivity. Results: A total of 221 residents from the classes of 2019 and 2020 were included. Most residents completed fellowship (75.9%) although less than half went on to academic practice (42.3%). Approximately one in five residents obtained secondary degrees (17.4%). Subjects averaged 3.15 (N = 208, SD = 4.51) publications while in medical school and 8.1 publications during residency (N = 209, SD = 10.0). For h-index calculated at the end of residency, having dedicated medical school research time was the only statistically significant factor (coefficient = 2.96, P = 0.002). Conclusions: Plastic surgery residents published more often as first authors and overall during residency than medical school, indicating increased research involvement and leadership. The present study builds upon prior studies by confirming the importance of dedicated medical school research time and its lasting impact. Understanding the associations of academic factors with increased research productivity in residency is relevant for both applicants and programs evaluating residency candidates.

Who's Auditioning Who? Applicant-Reported Elements of the Best and Worst Plastic Surgery Subinternships.

BACKGROUND: Many integrated plastic surgery applicants choose to complete one or more visiting subinternships or "away rotations" at programs outside of their home institution. As these rotations are so critical on both sides of the application process, the authors sought to identify the factors that influence subinternship experiences for plastic surgery applicants. METHODS: A survey was used to collect information about demographics, the subinternship experience, and interview preferences. The survey was distributed to current plastic surgery interns and applicants who applied to Duke Plastic Surgery in the 2019/2020 application cycle. RESULTS: One hundred forty-two responses were received (response rate, 35.2 percent). The mean number of subinternships completed was 4.47. The defining feature of respondents' best subinternship most often included engagement from faculty and residents, autonomy, and integration with the team. The worst feature of respondents' worst subinternship experience most often included a sense of disinterested or "malignant" residents and faculty, lacking operative/educational opportunities, and disorganization of the rotation. The majority of applicants (60.3 percent) would prefer to return for a standard interview day over interviewing while on rotation. CONCLUSIONS: The subinternship experience remains a critical part of the applicant experience when applying to integrated plastic surgery residency programs. The experience on these rotations leaves a lasting impression that is highly variable and influences future recommendations to peers. Rotating students value inclusivity and case volume, and they take note of negative interactions they witness among residents and faculty. These results can help as programs design their subinternship experience for visiting students in the future.

Light-Triggered Drug Release from Red Blood Cells Suppresses Arthritic Inflammation.

Arthritis is a leading cause of disability in adults, which can be intensely incapacitating. The location and intensity of the pain is both subjective and challenging to manage. Consequently, patient-directed delivery of anti-inflammatories is an essential component of future therapeutic strategies for the management of this disorder. We describe the design and application of a light responsive red blood cell (RBC) conveyed dexamethasone (Dex) construct that enables targeted drug delivery upon illumination of the inflamed site. The red wavelength (650 nm) responsive nature of the phototherapeutic was validated using tissue phantoms mimicking the light absorbing properties of various skin types. Furthermore, photoreleased Dex has the same impact on cellular responses as conventional Dex. Murine RBCs containing the photoactivatable therapeutic display comparable circulation properties as fluorescently labelled RBCs. In addition, a single dose of light-targeted Dex delivery is 5-fold more effective in suppressing inflammation than the parent drug, delivered serially over multiple days. These results are consistent with the notion that the circulatory system be used as an on-command drug depot, providing the means to therapeutically target diseased sites both efficiently and effectively.

Staying Close to Home: The Effects of COVID-19 on the Plastic Surgery Residency Match.

The 2019 novel coronavirus created unique challenges for the integrated plastic surgery match. The goal of this study was to evaluate the trends of the 2020 and 2021 integrated plastic surgery match specifically related to the 2019 novel coronavirus. METHODS: Three separate individual surveys were designed for integrated plastic surgery program directors and applicants from the 2021 to 2020 match. The surveys were distributed to the email addresses of applicants that applied to our institution's integrated residency program. Information of current interns and newly matched applicants from program websites and certified social media accounts were recorded. RESULTS: We received completed surveys from 19 of the 69 program directors for a response rate of 27.5%. The survey for the 2020 and 2021 match applicants was completed by 25 and 68 applicants, respectively, for a response rate of 6.1% and 21.9%. There was a significant difference in the average number of completed virtual subinternships between applicants that did and did not successfully match into plastic surgery (1.48 versus 0.36, P = 0.01). The rate of students matching at their home institution was the highest in 2021 at 26% compared to 2020 (18%) and 2019 (15%). CONCLUSIONS: The results of this study demonstrate that applicants were more likely to match at programs with which they had established previous connections, including home institutions. Applicants also had a higher likelihood to match if they completed a virtual subinternship during the 2021 match. Learning points can be applied to the upcoming application cycle to improve the overall experience.

Assessing the Utility of Post-Mastectomy Imaging after Breast Reconstruction.

BACKGROUND: Few guidelines exist regarding surveillance and diagnostic imaging after breast reconstruction. This study investigated the influence of breast reconstruction on the frequency of post-mastectomy imaging, the relative utility of imaging, and its effect on overall and locoregional recurrence-free survival. STUDY DESIGN: A retrospective review identified breast cancer patients (n = 1,216) who underwent mastectomy with or without reconstruction. Logistic regression identified surgical and oncologic predictors of post-reconstruction imaging. Kaplan-Meier method determined the impact of post-reconstruction imaging on overall and locoregional recurrence-free survival. RESULTS: Overall, 662 (54.4%) patients underwent mastectomy only and 554 (45.6%) underwent breast reconstruction. Patients undergoing reconstruction were more likely to receive imaging compared with patients undergoing mastectomy only (n = 205, 37.0% vs n = 168, 25.4%; p < 0.0001); however, this difference was not statistically significant after adjusting for age and follow-up time (p = 0.16). Most radiographic studies were Breast Imaging Reporting and Data System (BI-RADS) 1 (n = 58, 30%) or 2 (n = 95, 49%) and were ordered by nonsurgical providers (n = 128, 63%). Post-reconstruction imaging did not influence overall or locoregional recurrence-free survival. The 5-year survival probabilities for breast reconstruction patients who underwent imaging for a palpable mass, surveillance, or who did not undergo imaging were 100%, 95% (95% CI 89% to 100%), and 96% (95% CI 94% to 99%), respectively. Post-reconstruction imaging was not a significant predictor of overall survival (hazard ratio [HR] 0.95; 95% CI 0.61 to 1.46; p = 0.30). CONCLUSIONS: The limited utility of routine post-reconstruction imaging should be reinforced when evaluating breast reconstruction patients. Multidisciplinary collaboration should be emphasized when attempting to distinguish benign postoperative findings from a malignant process to reduce unnecessary imaging and biopsy after breast reconstruction.

The Influence of Fat Grafting on Breast Imaging after Postmastectomy Reconstruction: A Matched Cohort Analysis.

BACKGROUND: Fat grafting to the reconstructed breast may result in the development of benign lesions on physical examination, prompting further investigation with imaging and biopsy. The aim of this study was to assess the influence of fat grafting on the incidence of imaging and biopsies after postmastectomy reconstruction. METHODS: Patients who underwent autologous or implant-based reconstruction following mastectomy from 2010 to 2018 were identified. Those receiving fat grafting as part of their reconstructive course were propensity matched 1:1 to those that did not with body mass index, reconstruction timing, and reconstruction type as covariates in a multivariable logistic regression model. RESULTS: A total of 186 patients were identified, yielding 93 propensity-matched pairs. Fat-grafted patients had higher incidences of palpable masses (38.0 percent versus 18.3 percent; p = 0.003) and postreconstruction imaging (47.3 percent versus 29.0 percent; p = 0.01), but no significant difference in the number of biopsies performed (11.8 percent versus 7.5 percent; p = 0.32). Imaging was predominately interpreted as normal (Breast Imaging-Reporting and Data System 1, 27.9 percent) or benign (Breast Imaging-Reporting and Data System 2, 48.8 percent), with fat necrosis being the most common finding [n = 20 (45.5 percent)]. No demographic, oncologic, reconstructive, or fat grafting-specific variables were predictive of receiving postreconstruction imaging on multivariate analysis. Fat grafting was not associated with decreased 5-year overall survival or locoregional recurrence-free survival. CONCLUSIONS: Fat grafting to the reconstructed breast is associated with increased incidences of palpable masses and subsequent postreconstruction imaging with benign radiographic findings. Although the procedure is oncologically safe, both patients and providers should be aware that concerning physical examination findings can be benign sequelae of fat grafting and may lead to increased imaging after breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
