Virtual Mentoring: A Novel Approach to Facilitate Medical Student Applications to General Surgery Residency.

OBJECTIVE: The COVID-19 pandemic rapidly altered the landscape of medical education, particularly disrupting the residency application process and highlighting the need for structured mentorship programs. This prompted our institution to develop a virtual mentoring program to provide tailored, one-on-one mentoring to medical students applying to general surgery residency. The aim of this study was to examine general surgery applicant perception of a pilot virtual mentoring curriculum. DESIGN: The mentorship program included student-tailored mentoring and advising in 5 domains: resume editing, personal statement composition, requesting letters of recommendation, interview skills, and residency program ranking. Electronic surveys were administered following ERAS application submission to participating applicants. The surveys were distributed and collected via a REDCap database. RESULTS: Eighteen out of 19 participants completed the survey. Confidence in a competitive resume (p = 0.006), interview skills (p < 0.001), obtaining letters of recommendation (p = 0.002), personal statement drafting (p < 0.001), and ranking residency programs (p < 0.001) were all significantly improved following completion of the program. Overall utility of the curriculum and likelihood to participate again and recommend the program to others was rated a median 5/5 on the Likert scale (5 [IQR 4-5]). Confidence in the matching carried a premedian 66.5 (50-65) and a postmedian 84 (75-91) (p = 0.004). CONCLUSION: Following the completion of the virtual mentoring program, participants were found to be more confident in all 5 targeted domains. In addition, they were more confident in their overall ability to match. General Surgery applicants find tailored virtual mentoring programs to be a useful tool allowing for continued program development and expansion.

Racial disparities in triage of adolescent patients after bullet injury.

BACKGROUND: While pediatric trauma centers (PTCs) and adult trauma centers (ATCs) exhibit equivalent trauma mortality, the optimal care environment for traumatically injured adolescents remains controversial. Race has been shown to effect triage within emergency departments (EDs) with people of color receiving lower acuity triage scores. We hypothesized that African-American adolescents were more likely triaged to an ATC than a PTC compared with their White peers. METHODS: Institutional trauma databases from a neighboring, urban Level I PTC and ATC were queried for gunshot wounds in adolescents (15-18 years) presenting to the ED from 2015 to 2017. The PTC and ATC were compared in terms of demographics, services, and outcomes. Results were analyzed using univariate analysis and logistic regression. RESULTS: Among 316 included adolescents, 184 were treated in an ATC versus 132 in a PTC. Patients at the PTC were significantly more likely to be younger (16.1 vs. 17.5 years; p < 0.001), White (16% vs. 5%; p = 0.001), and privately insured (41% vs. 30%; p = 0.002). At each age, the proportion of Whites treated at the PTC exceeded the proportion of African-Americans. At the PTC, patients were more likely to receive inpatient and outpatient social work follow-up (89% vs. 1%, p < 0.001). Adolescents treated at the PTC were less likely to receive opioids (75% vs. 56%, p = 0.001) at discharge and to return to ED within 6 months (25% vs. 11%, p = 0.005). On multivariate logistic regression, African-American adolescents were less likely to be treated at a PTC (odds ratio, 0.30; 95% confidence interval, 0.10-0.85; p = 0.02) after controlling for age and Injury Severity Score. CONCLUSION: Disparities in triage of African-American and White adolescents after bullet injury lead to unequal care. African-Americans were more likely to be treated at the ATC, which was associated with increased opioid prescription, decreased social work support, and increased return to ED. LEVEL OF EVIDENCE: Therapeutic/Care Management, Level IV.

The impact of retained bullet fragments on outcomes in patients with gunshot wounds.

BACKGROUND: Nationally, 115,000 non-fatal firearm injuries occurred in 2017, with many such victims possessing retained bullet fragments (RBFs); however, the impact of RBFs has not been well studied. METHODS: An institutional trauma database from an urban, level one trauma center was queried for patients presenting with gunshot wounds (GSWs) to the ED in 2017. GSWs were stratified by the presence or absence of RBFs. Groups were compared using t-tests, chi-squared, and logistic regression. RESULTS: Of 674 patients with GSWs who met inclusion criteria, 394 had RBFs versus 280 with no RBFs. Patients with RBFs were more likely admitted from the ED (57.4% vs. 41.8%, p < 0.001), had significantly higher rates of return to the ED within six months (30.7% vs. 18.6%, p < 0.001), and higher rates of subsequent GSW in the next year (5.1% vs. 1.8%, p = 0.03). On return to ED, 17.6% of those with a RBF had symptoms associated with their RBF. CONCLUSION: RBFs may represent an unrecognized risk factor for both repeat ED visits and subsequent bullet injury.

A prospective cohort study to analyze the interaction of tumor-to-breast volume in breast conservation therapy versus mastectomy with reconstruction.

PURPOSE: We explored the impact of the relative volume of a tumor versus the entire breast on outcomes in patients undergoing breast conservation therapy (BCT) versus mastectomy and reconstruction (M + R). We hypothesized that there would be a threshold tumor:breast ratio (TBR) below which patient-reported outcomes (PRO) would favor BCT and above which would favor M + R. METHODS: We conducted a prospective cohort study of patients with ductal carcinoma in situ (DCIS) or invasive breast cancers undergoing BCT or M + R. A prerequisite for inclusion, analysis of tumor and breast volumes was conducted from three-dimensional magnetic resonance imaging reconstructions to calculate the TBR. Three-dimensional photography was utilized to calculate pre- and postoperative volumes and assess symmetry. Oncologic, surgical, and patient-reported outcome data were obtained from relevant BREAST-Q modules administered pre- and postoperatively. RESULTS: The BCT cohort had significantly smaller tumor volumes (p = 0.001) and lower TBRs (p = 0.001) than patients undergoing M + R overall. The M + R group, however, comprised a broader range of TBRs, characterized at lower values by patients opting for contralateral prophylactic mastectomy. Postoperative satisfaction with breasts, psychosocial, and sexual well-being scores were significantly higher in the BCT cohort, while physical well-being significantly favored the M + R cohort 480.2 ± 286.3 and 453.1 ± 392.7 days later, respectively. CONCLUSIONS: Relative to BCT, M + R was used to manage a broad range of TBRs. The relative importance of oncologic and surgical risk reduction, symmetry, and number of procedures can vary considerably and may limit the utility of TBR as a guide for deciding between BCT and M + R.

Overlapping Surgery in Plastic Surgery: An Analysis of Patient Safety and Clinical Outcomes.

BACKGROUND: Overlapping surgery is an important and controversial health care issue. To date, there is minimal evidence on the safety of overlapping surgery in plastic surgery. The purpose of this study was to evaluate and compare outcomes for patients undergoing overlapping surgery versus nonoverlapping surgery in plastic surgery. METHODS: This is a retrospective cohort study of consecutive patients undergoing plastic surgery procedures at a tertiary academic center between January of 2016 and January of 2018. Demographic and procedural characteristics, clinical outcomes, and adverse events were analyzed for patients undergoing overlapping versus nonoverlapping surgery. An a priori power analysis was performed, and chi-square, Wilcoxon rank sum, and bivariate logistic regression tests were used for analyses. RESULTS: Eight hundred sixty-six patients constituted the study population: 555 (64.1 percent) underwent nonoverlapping surgery and 311 (35.9 percent) underwent overlapping surgery. There was no significant difference (p > 0.050) in mean age, body mass index, tobacco use, American Society of Anesthesiologists rating, or Charlson Comorbidity Index score between cohorts. Comparison of nonoverlapping and overlapping cases revealed no differences in complications (12.1 percent versus 11.9 percent; p = 0.939), reoperations (6.1 percent versus 6.8 percent; p = 0.717), readmissions (3.6 percent versus 3.5 percent; p = 0.960), or emergency room visits (4.7 percent versus 4.8 percent; p = 0.927). Stratification by procedure demonstrated no difference (p > 0.050) in complications between cohorts. Median operative time was significantly longer for overlapping operations (105 minutes versus 83 minutes; p = 0.004). CONCLUSIONS: This study supports the safety of overlapping surgery in plastic surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Vaginal Laxity, Sexual Distress, and Sexual Dysfunction: A Cross-Sectional Study in a Plastic Surgery Practice.

BACKGROUND: Sexual health issues can be characterized by vaginal laxity (VL), sexual distress, and sexual dysfunction. The epidemiology of these issues in plastic surgery patients, and especially breast cancer survivors, remains poorly understood. OBJECTIVES: To prospectively assess sexual health issues in a plastic surgery patient population with and without breast cancer. METHODS: A prospective cohort study was created in our practice from June to August 2017 with administration of a survey including the vaginal laxity questionnaire (VLQ), female sexual distress scale-revised (FSDS-R), and female sexual function index (FSFI). Multivariate logistic regression identified the controlled effect of patient variables on development of sexual health issues. RESULTS: Of 291 patients solicited, 239 completed the survey (37.7% breast cancer survivors vs 62.3% without). Prevalence of VL was nearly 1 in 6 women. Of these, 46.0% met criteria for sexual distress (FSDS-R ≥ 11.0) and 64.8% had sexual dysfunction (FSFI ≤ 26.5). Breast cancer survivors exhibited significantly greater overall sexual dysfunction (P < 0.001) and greater dysfunction within all FSFI domains of desire, arousal, lubrication, orgasm, satisfaction, and pain (all P < 0.02). On multivariate regression, number of vaginal deliveries predicted development of VL (OR 1.87, P < 0.001), presence of VL predicted sexual distress (OR 3.01, P = 0.007), while history of breast cancer predicted sexual dysfunction (OR 1.87, P < 0.05). CONCLUSIONS: Sexual health issues are prevalent amongst plastic surgery patients. Aesthetic practices can improve patients' quality of life by focusing on these areas. Potential therapeutic options to address sexual health issues should consider addressing vaginal laxity.

DNA Binding Polyamides and the Importance of DNA Recognition in their use as Gene-Specific and Antiviral Agents.

There is a long history for the bioorganic and biomedical use of N-methyl-pyrrole-derived polyamides (PAs) that are higher homologs of natural products such as distamycin A and netropsin. This work has been pursued by many groups, with the Dervan and Sugiyama groups responsible for many breakthroughs. We have studied PAs since about 1999, partly in industry and partly in academia. Early in this program, we reported methods to control cellular uptake of polyamides in cancer cell lines and other cells likely to have multidrug resistance efflux pumps induced. We went on to discover antiviral polyamides active against HPV31, where SAR showed that a minimum binding size of about 10 bp of DNA was necessary for activity. Subsequently we discovered polyamides active against two additional high-risk HPVs, HPV16 and 18, a subset of which showed broad spectrum activity against HPV16, 18 and 31. Aspects of our results presented here are incompatible with reported DNA recognition rules. For example, molecules with the same cognate DNA recognition properties varied from active to inactive against HPVs. We have since pursued the mechanism of action of antiviral polyamides, and polyamides in general, with collaborators at NanoVir, the University of Missouri-St. Louis, and Georgia State University. We describe dramatic consequences of ß-alanine positioning even in relatively small, 8-ring polyamides; these results contrast sharply with prior reports. This paper was originally presented by JKB as a Keynote Lecture in the 2nd International Conference on Medicinal Chemistry and Computer Aided Drug Design Conference in Las Vegas, NV, October 2013.

Alternative sources of adult stem cells: a possible solution to the embryonic stem cell debate.

The complex moral and ethical debate surrounding the definition of the origins of human life, together with conflicting current and proposed legislation on state and federal levels, is hindering the course of research into the therapeutic uses of human embryonic stem cells. However, newly identified sources of adult stem cells, free from many of the ethical and legal concerns attached to embryonic stem cell research, may offer great promise for the advancement of medicine. These alternative sources may alleviate the need to resolve the stem cell debate before further therapeutic benefits of stem cell research can be realized. While legislation and ethics evolve to address the legal and moral issues of embryonic stem cell research, innovative researchers will continue to search for and find real and present solutions for cell-based therapies using adult stem cells.

Automation and validation of DNA-banking systems.

DNA banking is one of the central capabilities on which modern genetic research rests. The DNA-banking system plays an essential role in the flow of genetic data from patients and genetics researchers to the application of genetic research in the clinic. Until relatively recently, large collections of DNA samples were not common in human genetics. Now, collections of hundreds of thousands of samples are common in academic institutions and private companies. Automation of DNA banking can dramatically increase throughput, eliminate manual errors and improve the productivity of genetics research. An increased emphasis on pharmacogenetics and personalized medicine has highlighted the need for genetics laboratories to operate within the principles of a recognized quality system such as good laboratory practice (GLP). Automated systems are suitable for such laboratories but require a level of validation that might be unfamiliar to many genetics researchers. In this article, we use the AstraZeneca automated DNA archive and reformatting system (DART) as a case study of how such a system can be successfully developed and validated within the principles of GLP.
