Exploring Limited English Proficiency in the Clinical Outcomes of Pediatric Burn Patients.

INTRODUCTION: Limited English proficiency (LEP) is linked to lower health care access and worse clinical outcomes. This study aims to explore the potential role of LEP on clinical outcomes of pediatric burn patients. METHODS: We conducted a single-institution retrospective study of burn patients presenting at a tertiary pediatric burn referral program between January 2016 and December 2020. Patient demographics, burn mechanism, severity, interventions, and primary patient language were abstracted from the electronic health record. Clinical outcomes (length of stay [LOS], clinic follow-up, and 30-day readmission) of patients with LEP were compared to patients with English as primary language (EPL). RESULTS: Thirty-five (4.2%) patients with LEP were identified of 840 total patients. On univariate analysis, there was no difference in mean total body surface area (6.5% versus 6.1%), report of physical abuse (2.9% versus 8.9%), or need for grafting (14.3% versus 15.0%) comparing patients with LEP to those with EPL. Patients with LEP were more likely to have a scald burn (68.6% versus 48.9%, P = 0.025) and less likely to have a flame/fire burn (20.0% versus 37.6%, P = 0.047). On multivariate analysis, there was no difference between patients with LEP compared to patients with EPL for LOS (2.9 versus 3.5 d), 30-day readmissions (5.6% versus 5.7%), or clinic follow-up (80.6% versus 75.0%). In patients with >10% total body surface area, patients with LEP had a longer emergency department LOS (277 min versus 145 min, P = 0.06) but no difference in outcome measures. CONCLUSIONS: Pediatric patients with LEP were not found to have worse burn outcomes compared to EPL patients in our patient sample. However, a true association is difficult to determine given the small sample size of LEP patients and the potential underestimation of language discordancy as recorded in the electronic medical record. Further research is needed to better explore the role of primary language and health communication as a social determinant of health in pediatric burn patients.

Postoperative Respiratory Complications in SARS-CoV-2 Positive Pediatric Patients Across 20 United States Hospitals: A Cohort Study.

INTRODUCTION: Data examining rates of postoperative complications among SARS-CoV-2 positive children are limited. The purpose of this study was to evaluate the impact of symptomatic and asymptomatic SARS-CoV-2 positive status on postoperative respiratory outcomes for children. METHODS: This retrospective cohort study included SARS-CoV-2 positive pediatric patients across 20 hospitals who underwent general anesthesia from March to October 2020. The primary outcome was frequency of postoperative respiratory complications, including: high-flow nasal cannula/non invasive ventilation, reintubation, pneumonia, Extracorporeal Membrane Oxygenation (ECMO), and 30-day respiratory-related readmissions or emergency department (ED) visits. Univariate analyses were used to evaluate associations between patient and procedure characteristics and stratified analyses by symptoms were performed examining incidence of complications. RESULTS: Of 266 SARS-CoV-2 positive patients, 163 (61.7%) were male, and the median age was 10 years (interquartile range 4-14). The majority of procedures were emergent or urgent (n = 214, 80.5%). The most common procedures were appendectomies (n = 78, 29.3%) and fracture repairs (n = 40,15.0%). 13 patients (4.9%) had preoperative symptoms including cough or dyspnea. 26 patients (9.8%) had postoperative respiratory complications, including 15 requiring high-flow oxygen, 8 with pneumonia, 4 requiring non invasive ventilation, 3 respiratory ED visits, and 2 respiratory readmissions. Respiratory complications were more common among symptomatic patients than asymptomatic patients (30.8% vs. 8.7%, p = 0.01). Higher ASA class and comorbidities were also associated with postoperative respiratory complications. CONCLUSIONS: Postoperative respiratory complications are less common in asymptomatic versus symptomatic SARS-COV-2 positive children. Relaxation of COVID-19-related restrictions for time-sensitive, non urgent procedures in selected asymptomatic patients may be reasonably considered. Additionally, further research is needed to evaluate the costs and benefits of routine testing for asymptomatic patients. LEVEL OF EVIDENCE: Iii, Respiratory complications.

Structural evaluation of child physical abuse in trauma: Social determinants of health at the population level.

PURPOSE: Child physical abuse (CPA) is closely linked to social factors like insurance status with limited evaluation at a structural population-level. This study evaluates the role of social determinants of health within the built environment on CPA. METHODS: A single-institution retrospective review of pediatric trauma patients was conducted between January 2016 and December 2020. Patient address was geocoded to the census-tract level. Socioeconomic metrics, including poverty rate, supermarket access and Social Vulnerability Index (SVI) were estimated from the Food Access Research Atlas. Univariate and multivariable regression analyses were conducted to compare demographics and outcomes. RESULTS: Of 3,540 patients, 317 (9.0%) had concern for physical abuse reported in the registry. CPA patients were younger (7.5 vs 9.6 years, p<0.0001) and more often Black (37.0%, N = 117 vs 23.5%, N = 753; p<0.0001). CPA had higher injury severity scores (ISS) (7.9 vs 5.8, p<0.0001) and longer length of stay (5.3 vs 2.9 days, p<0.0001). CPA had higher Medicaid (73.0%, N = 232 vs 53.8%, N = 1748, p<0.0001) and SVI (0.65 vs 0.59, p<0.0001) with lower median income ($52,100 vs $56,100, p<0.0001) and more low-food access tracts (59.6% vs 53.6%, p = 0.06). Combined low-income and low-food access populations showed widened disparities (40.0% vs 28.9%, p = 0.0002). On multivariate analysis, CPA was associated with poverty (OR 2.3, 95% CI [0.979, 3.60], p = 0.0006), low-access Black share (OR 3.3, 95% CI [1.18, 5.47], p = 0.002) and urban designation (OR 1.5, 95% CI [1.13, 1.87], p = 0.004). CONCLUSION: The built-environment and population-level social determinants of health are related to child physical abuse and should influence advocacy and prevention. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective.

Management of pediatric appendicitis during the COVID-19 pandemic: A nationwide multicenter cohort study.

BACKGROUND: The COVID-19 pandemic has impacted timely access to care for children, including patients with appendicitis. This study aimed to evaluate the effect of the COVID-19 pandemic on management of appendicitis and patient outcomes. METHODS: A multicenter retrospective study was performed including 19 children's hospitals from April 2019-October 2020 of children (age≤18 years) diagnosed with appendicitis. Groups were defined by each hospital's city/state stay-at-home orders (SAHO), designating patients as Pre-COVID (Pre-SAHO) or COVID (Post-SAHO). Demographic, treatment, and outcome data were obtained, and univariate and multivariable analysis was performed. RESULTS: Of 6,014 patients, 2,413 (40.1%) presented during the COVID-19 pandemic. More patients were managed non-operatively during the COVID-19 pandemic compared to before the pandemic (147 (6.1%) vs 144 (4.0%), p < 0.001). Despite this change, there was no difference in the proportion of complicated appendicitis between groups (1,247 (34.6%) vs 849 (35.2%), p = 0.12). COVID era non-operative patients received fewer additional procedures, including interventional radiology (IR) drain placements, compared to pre-COVID non-operative patients (29 (19.7%) vs 69 (47.9%), p < 0.001). On adjusted analysis, factors associated with increased odds of receiving non-operative management included: increasing duration of symptoms (OR=1.01, 95% CI: 1.01-1.012), African American race (OR=2.4, 95% CI: 1.3-4.6), and testing positive for COVID-19 (OR=10.8, 95% CI: 5.4-21.6). CONCLUSION: Non-operative management of appendicitis increased during the COVID-19 pandemic. Additionally, fewer COVID era cases required IR procedures. These changes in the management of pediatric appendicitis during the COVID pandemic demonstrates the potential for future utilization of non-operative management.

Social determinants of health in pediatric scald burns: Is food access an issue?

BACKGROUND: Burn injury risk, severity, and outcomes have been associated with socioeconomic status. Limited data exist to evaluate health access-related influences at a structural population level. This study evaluated factors at the Census-tract level, specifically evaluating food access and social vulnerability in pediatric scald burns. METHODS: A single-institution retrospective review using the trauma registry and electronic medical record was conducted of pediatric burns between 2016 and 2020. Home address was coded to the Census-tract level and bulk analyzed. Socioeconomic metrics of the home environment were evaluated from publicly available databases, the United States Food and Drug Administration Food Access Research Atlas, and the Centers for Disease Control's Social Vulnerability Index. RESULTS: There were 840 patients that met inclusion criteria (49.8% scald, N = 418). The mean total body surface area for scalds was 6.6% with an age of 10.2 years; 76% (n = 317) of scalds had Medicaid, and 15% (n = 63) were due to hot noodles. Scalds occurred more in females (45.7%, N = 191 vs 28.0%, N = 118; P < .0001), non-White race (62.7%, N = 262 vs 29.1%, N = 123; P < .0001), and low-income and low-food access populations (39.8%, N = 147 vs 30.4%, N = 116; P = .007). Low-food access Black populations showed increased scald injury (18% [interquartile range 6-35] vs 10% [interquartile range 4-25]), whereas all other populations showed no association. The patients with scalds had a higher overall social vulnerability index (0.67 vs 0.62, P = .008). CONCLUSION: Often related to poverty, health access, and health equity, population-level social determinants of health like social vulnerability and food access have significant impact on health care and should influence health outreach and systems improvement.

Enterobius vermicularis-associated appendicitis: A 22-year case series and comprehensive review of the literature.

INTRODUCTION: Enterobius vermicularis is known to be associated with appendicitis, however a causal relationship between Enterobius and appendicitis has not been established. The aim of this study was to explore the relationship between appendiceal Enterobius and histologic appendicitis. METHODS: A retrospective review was performed of all pediatric appendectomies between 1997 and 2019. Patients with diagnosed with Enterobius were included for analysis. Patient demographics, operative findings, and pathologic reports were queried. Data were entered into an encrypted database and subsequently analyzed. A comprehensive review of the literature was also conducted. RESULTS: Thirty-eight cases of Enterobius-associated appendicitis were identified out of 3541 (1.07%). Grossly normal appendices at operation were seen in 27% of patients. Inflammatory infiltrate was noted on histopathology in 78.3%, and Enterobius was considered to be the cause of that inflammation in 68.4%. The comprehensive literature review revealed 19 articles (1.87% incidence) that noted 35% of patients with appendiceal Enterobius had appendicitis on either histopathology or gross evaluation. CONCLUSION: The high rate of inflammation on pathology found among our patients with pinworm appendicitis suggests an association with presentation as acute appendicitis. Our comprehensive review revealed a higher proportion of Enterobius appendicitis. Treatment with antihelminthic therapy is recommended. LEVEL OF EVIDENCE (LOE): Level IV(4)-case series and comprehensive review.

Medical Student Career Choice: Who Is the Influencer?

BACKGROUND: While many factors influence medical student career choice, interactions with attending and resident physicians during clinical rotations are particularly important. To evaluate the influence of attending and resident physicians on medical students' career choices, particularly for those pursuing surgical careers, we quantified their respective influence in the context of other known influences. METHODS: Rising fourth-year medical students and new graduates were given an IRB-exempt, 14-item online survey. Descriptive statistics were performed on the demographic information. Chi-square analysis was used, as were Kruskal-Wallis and Mann-Whitney analyses on the Likert responses (α = 0.05). RESULTS: Survey response was 24%. Students pursuing general surgery rated residents greater than or equal to attendings on 7 of 8 key mentoring characteristics. Of students choosing a different specialty than the one they intended to pursue upon entering medical school, the influence of residents was cited by 100% of the students pursuing general surgery, compared to 59% of the entire cohort. Identification of a role model and perceived personality fit were significantly more important than other factors (P < 0.0001). Students pursuing general surgery rated the importance of identifying a role model and perceived personality fit greater than their peers. CONCLUSIONS: Residents have greater influences on medical students' career choice compared to attendings. Students pursuing a surgical specialty, particularly general surgery, considered the influence of role models and perceived personality fit to be the most important factors in their specialty decision. These findings provide valuable insights to improve student experiences and career recruitment in surgical specialties, particularly general surgery.

Analysis of Outcomes in Adolescents and Young Adults With Pilonidal Disease.

Purpose: Numerous definitive surgical techniques exist for the treatment of pilonidal disease with varied recurrence rates and wound complications. Due to the wide array of techniques and lack of consensus on the best approach, we proposed to study our experience treating pilonidal disease in adolescents and young adults. Methods: A retrospective analysis was conducted of patients 10-24 years old treated at a tertiary medical center from 2011 to 2016. Data including demographics, management, and outcomes were collected and analyzed. Primary outcome was recurrence of disease. Results: One hundred and thirty three patients with pilonidal disease underwent operative management. Fifty one percent underwent primary closure and 49% healed by secondary intention with no significant difference in recurrence rates (primary 18%, secondary 11%; p = 0.3245). Secondary healing patients had significantly lower wound complication rates (primary 51%, secondary 23%; p = 0.0012). After accounting for sex, race, weight, and operative technique, age was predictive of disease recurrence with an adjusted odds ratio (OR) of 0.706 (0.560-0.888; p = 0.003). Age and sex were both predictive of wound complications. Older patients had decreased risk of wound complication (adjusted OR 0.806, 95% CI 0.684-0.951; p = 0.0105), and male patients had increased risk of wound complication (adjusted OR 2.902, 95% CI 1.001-8.409; p = 0.0497). Conclusion: In summary, there is no significant difference in the recurrence rates between operative techniques for pilonidal disease. Older patients have decreased risk of recurrence following intervention. Wound complication rates are lower in patients undergoing secondary healing, though this may be better explained by differences in age and sex. Additional research investigating newer, minimally-invasive techniques needs to be pursued.

Outcomes After Prehospital Endotracheal Intubation in Suburban/Rural Pediatric Trauma.

BACKGROUND: Trauma is the leading cause of death in pediatric patients over 1 y of age. Controversy exists regarding prehospital airway management for these patients, with some studies suggesting that endotracheal intubation in the field or at a referring hospital is associated with increased mortality and complication rate. These studies were largely performed at urban centers, and it is unclear whether the results apply to suburban/rural networks with longer transport times and more stops at referring hospitals. The purpose of this study is to evaluate differential outcomes in pediatric trauma patients who underwent endotracheal intubation at the scene of injury, referring hospital, or pediatric trauma center in a predominantly rural/suburban setting. MATERIALS AND METHODS: A retrospective review was performed evaluating trauma patients age 18 y or younger at a single institution over 10 y (2004-2014). Patients were selected who underwent endotracheal intubation and were classified based on location of intubation (scene, referring hospital, or trauma center). Fischer's exact test and t-tests were performed for comparison. Univariate and multivariate regression analyses were performed. RESULTS: 288 patients were identified. 155 (53.8%) were intubated at the scene of injury, 55 (19.1%) at a referring hospital, and 72 (25%) at the trauma center. Overall mortality was 21.9%, which was highest in the scene intubation group (29.7%) compared with the referring hospital (20%) and trauma center (5.6%) groups (P < 0.01). Patients intubated at the scene had higher Injury Severity Scores and lower Glasgow Coma Scale scores (P < 0.01). Duration of intubation was lowest in the trauma center group (P < 0.01). Complication rate was highest in the referring hospital group (P < 0.05). Multivariate analysis revealed that age, injury severity, and neurologic status were the key drivers of mortality rather than location of intubation. CONCLUSIONS: Mortality and duration of intubation were lowest in trauma patients intubated at a pediatric trauma center. However, location of intubation was not a significant independent predictor of mortality or complications on multivariate analysis, suggesting that age, injury severity, and neurologic status are the main indicators of prognosis in severe pediatric trauma.

Primary B cell repertoire remodeling to achieve humoral transplantation tolerance.

The current mainstay of immunotherapy in clinical transplantation is T lymphocyte directed. However, it has long been appreciated that the emergence of an alloimmune response mounted by the B lymphocyte compartment and detectable as donor-specific antibodies is a critical challenge to long-term graft survival. Thus, achieving robust transplantation tolerance will require induction of tolerance in both the T- and B-cell compartments. Here we propose that the natural developmental propensity of the B-lymphocyte compartment acquisition of tolerance to self-antigens can be recapitulated to achieve humoral transplantation tolerance. It is our contention B-lymphocyte directed induction immunotherapy would be an important component of emerging strategies for induction of Transplantation tolerance.

Underutilization of A2 ABO incompatible kidney transplantation.

BACKGROUND: ABO compatibility creates a disadvantage for O and B renal allograft candidates. A2 ABO incompatible transplant may decrease waiting times and generate equivalent graft survival to an ABO compatible transplant. METHODS: Death-censored graft survival was compared between A recipients and O, B, and AB recipients of an A2 allograft with multivariate Cox regression models utilizing data from the United Network of Organ Sharing (UNOS) between 1997 and 2007. RESULTS: Eighty-five percent of A2 kidneys were transplanted into ABO compatible recipients vs. 15% into ABO incompatible recipients. Rates of A2 incompatible kidney transplants did not increase over the study period (14.8% to 14.6%). Mean wait time for A2→O kidneys was 337 vs. 684 d for O→O and for A2→B kidneys, 542 vs. 734 d for B→B. Adjusted relative risk of graft loss at five-yr was similar between O, B, and AB recipients compared to A recipients of an A2 allograft, corresponding to a five-yr graft survival of 84%, 86.2%, 86.1%, and 86.1%, respectively. CONCLUSION: A2 incompatible kidney transplantation is underutilized. Graft outcomes are similar among A2 compatible and incompatible recipients. Shorter waiting time and improved access might be achieved if A2 kidneys are considered in all blood groups.

Essential role for B cells in transplantation tolerance.

T lymphocytes are the primary targets of immunotherapy in clinical transplantation. However, B lymphocytes are detrimental to graft survival by virtue of their capacity to present antigen to T cells via the indirect pathway of allorecognition and the generation of donor specific alloantibody. Furthermore, the long-term survival of organ allografts remains challenged by chronic rejection, a process in which activated B cells have been found to play a significant role. Therefore, the achievement of transplantation tolerance will likely require induction of both T and B cell tolerance to alloantigens. Moreover, human and animal investigations have shown that subsets of B cells, Transitional and Regulatory, are inherently tolerogenic. Developing therapeutic strategies that exploit these populations may be key to achieving transplantation tolerance. In this review we describe the current evidence for the essential role of B cells in transplant tolerance and discuss emerging B cell directed strategies to achieve allograft tolerance.

Strategies for B-lymphocyte repertoire remodeling in transplantation tolerance.

Transplantation tolerance remains an elusive goal as B-cell-initiated chronic humoral rejection evades current immunosuppression. B-cell-directed therapy is thus emerging as a key component in achieving transplantation tolerance and long-term graft survival. Here, we propose strategies of B-cell repertoire remodeling to achieve humoral unresponsiveness to donor antigens with implementation of fundamental B-cell immunobiology and use of newly developed B-cell-directed agents.
