Predicting General Surgery Match Outcomes Using Standardized Ranking Metrics.

INTRODUCTION: Objective measurements for applicant ranking are becoming increasingly important, not only to help address the growing number of general surgery applicants each year but also to minimize bias and ensure consistency. We assessed if our general surgery applicant scoring system was an effective tool for accurately predicting the results of the resident match. METHODS: A retrospective review of applicant rank lists from 2017 to 2020 was conducted. Applicants were ranked based on the sum of preinterview and interview scores. The preinterview score is an objective metric related to the applicant's academic portfolio. The interview score is a standardized score based on interview performance. We reviewed match results from ranked candidates and categorized them as academic categorical (AC), community categorical (CC), preliminary surgical (PS), nonsurgical specialty (NS), or unmatched (UM) positions. RESULTS: A total of 378 applicants were interviewed. Forty-nine percent matched into AC, 22% into CC, 11% into PS, and 5% into NS positions, while 13% of the interviewees were UM. Applicants who matched into AC positions had significantly higher preinterview and interview scores than applicants in other categories. Applicants who matched into CC positions had significantly higher interview scores than those categorized as UM, but their preinterview scores did not differ significantly from the UM group. Applicants who did not match into a categorical position (PS, NS, or UM) did not have significantly different preinterview or interview scores from one another. CONCLUSIONS: Our standardized scoring system was effective in stratifying which applicants would match into categorical general surgery residency programs.

Implications of Demographics and Socioeconomic Factors in Breast Cancer Reconstruction.

BACKGROUND: Not all women undergo breast reconstruction despite its vital role in the recovery process. Previous studies have reported that women who are ethnically diverse and of lower socioeconomic status are less likely to undergo breast reconstruction, but the reasons remain unclear. The purpose of this study is to evaluate the demographic characteristics of our patient population and their primary reason for not undergoing breast reconstruction. METHODS: An institutional review board-approved, single-institution study was designed to evaluate all female breast cancer patients of all stages who underwent mastectomy but did not undergo breast reconstruction from 2008 to 2014. Patients were contacted via telephone and asked to participate in a validated, prompted survey. Data regarding their demographic information and primary reason for not undergoing breast reconstruction were collected. RESULTS: Inclusion criteria were met by 181 patients, of which 61% participated in the survey. Overall, the most common reason for not undergoing breast reconstruction (26%) was unwillingness to undergo further procedures. However, the most common reason for patients that identified as Hispanic, Spanish-speaking, high school graduates, or having an annual income less than US $25,000 (P < 0.05) was insufficient information received. CONCLUSIONS: This study demonstrates that ethnicity and socioeconomic factors play a key role in determining why patients forego breast reconstruction. Ethnicity, language, education, income, and employment status are associated with patients not receiving appropriate education regarding their reconstructive options. Breast surgeons with a diverse patient population should ensure that these patients are adequately educated regarding their options, and if perhaps, more of these patients would decide to partake in the reconstruction process.

Intra-Peritoneal Pseudocyst as a Rare Complication After Peritoneal Dialysis: The Use of a Staged Surgical Approach in Management.

Despite its numerous benefits, peritoneal dialysis (PD) can rarely result in dangerous and even life-threatening complications, including peritonitis, hernias, encapsulating peritoneal sclerosis (EPS), and rarely peritoneal pseudocysts. Herein, we present a rare case of a giant intra-peritoneal pseudocyst that presented four months following the discontinuation of a 5-year course of complicated PD. Despite the initially successful drainages, the patient's symptoms continued to recur, and the imaging findings were concerning for underlying neoplastic processes. As such, a staged surgical approach was performed, starting with a diagnostic laparoscopy and was subsequently followed with cyst excision and marsupialization to the peritoneal cavity. While previous reports of such rare pseudocyst have been documented in the literature as a complication of PD, to our knowledge, this is the second case of pseudocyst formation to occur months after the discontinuation of PD therapy. This case emphasizes the importance of close follow-up in PD patients and showcases how a staged surgical approach can be utilized to accurately diagnose and manage such complicated cases.

Extracorporeal Membrane Oxygenation for Pediatric Burn Patients: Is Management Improving Over Time?

Over the last few decades, extracorporeal membrane oxygenation (ECMO) has become a lifesaving modality for patients with severe respiratory failure following burn injury. With the advancement in critical care and ECMO management, this study aims to analyze the outcomes of ECMO in pediatric burn patients. The Extracorporeal Life Support Organization database was queried from 1999 to 2018 for patients 18 years old and under with a burn injury. The data were divided into two decades, the first (1999-2008) and the second (2009-2018), for analysis of background characteristics and clinical outcomes. Ninety-five patients met inclusion criteria. The overall use of ECMO increased in the second decade (60 cases) when compared to the first decade (35 cases), and use of venovenous ECMO increased in the second decade from 16 cases to 38 cases. Although more patients survived because of the increased application of venovenous ECMO, the survival rate was unchanged between decades (53.4% vs. 54.3%; P = 0.937). Patients with pre-ECMO cardiac arrest had a significant improvement in mortality during the second decade (54.5% vs. 0%; P = 0.043). Metabolic (P = 0.022) and renal (P = 0.043) complications were most common in nonsurvivors during the first decade whereas cardiovascular (P = 0.031) and neurologic (P = 0.003) complication were higher in the second decade (P = 0.031, 0.003). Use of ECMO after burn injury has become more common; however, overall mortality remains unchanged. The data suggests pre-ECMO cardiac arrest is no longer a contraindication to start ECMO.

Effect of Mitochondrial Antioxidant (Mito-TEMPO) on Burn-Induced Cardiac Dysfunction.

BACKGROUND: Imbalance of oxidants/antioxidants results in heart failure, contributing to mortality after burn injury. Cardiac mitochondria are a prime source of reactive oxygen species (ROS), and a mitochondrial-specific antioxidant may improve burn-induced cardiomyopathy. We hypothesize that the mitochondrial-specific antioxidant, Triphenylphosphonium chloride (Mito-TEMPO), could protect cardiac function after burn. STUDY DESIGN: Male rats had a 60% total body surface area (TBSA) scald burn injury and were treated with/without Mito-TEMPO (7 mg/kg-1, intraperitoneal) and harvested at 24 hours post-burn. Echocardiography (ECHO) was used for measurement of heart function. Masson Trichrome and hematoxylin and eosin (H & E) staining were used for cardiac fibrosis and immune response. Qualitative polymerase chain reaction (qPCR) was used for mitochondrial DNA replication and gene expression. RESULTS: Burn-induced cardiac dysfunction, fibrosis, and mitochondrial damage were assessed by measurement of mitochondrial function, DNA replication, and DNA-encoded electron transport chain-related gene expression. Mito-TEMPO partially improved the abnormal parameters. Burn-induced cardiac dysfunction was associated with crosstalk between the NFE2L2-ARE pathway, PDE5A-PKG pathway, PARP1-POLG-mtDNA replication pathway, and mitochondrial SIRT signaling. CONCLUSIONS: Mito-TEMPO reversed burn-induced cardiac dysfunction by rescuing cardiac mitochondrial dysfunction. Mitochondria-targeted antioxidants may be an effective therapy for burn-induced cardiac dysfunction.

Nanoantibiotics: a new paradigm for the treatment of surgical infection.

Infections following orthopedic device implantations often impose a substantial health burden and result in high medical costs. Currently, preventative methods are often employed following an orthopedic implant to reduce risk of infection; however, contamination of the surgical site can still occur. Although antibiotics have demonstrated a substantial reduction in bacterial growth and maintenance, biofilm formation around the implant can often minimize efficacy of the antibiotic. Recently, nanotechnology has garnered significant interest, resulting in the development of several antibiotic delivery strategies that exhibit extended release and increased efficacy. In this review, treatment methods of orthopedic-device-related infections will be discussed and an overview of antimicrobial-based nanotechnologies will be provided. Specifically, nonmetal-, metal- and oxide-based nanotechnologies, incorporating antibacterial strategies, will be discussed.
