Management of Persistent Low-Suspicion Cervical Lymphadenopathy in Pediatric Patients.

INTRODUCTION: Cervical lymphadenopathy in children is typically self-limited; however, the management of persistent lymphadenopathy remains unclear. This study aimed to evaluate the management and outcomes of patients with persistent cervical lymphadenopathy. METHODS: Single-institution, retrospective review of children <18 years undergoing ultrasound (US) for cervical lymphadenopathy from 2013 to 2021 was performed. Patients were stratified into initial biopsy, delayed biopsy, or no biopsy groups. Clinical characteristics and workup were compared, and multivariate analyses were performed to assess predictors of delayed biopsy. RESULTS: 568 patients were identified, with 493 patients having no biopsy, 41 patients undergoing initial biopsy, and 34 patients undergoing delayed biopsy. Presenting symptoms differed: no biopsy patients were younger, were more likely to present to the emergency department, and had clinical findings often associated with acute illness. Patients with USs revealing abnormal vascularity or atypical architecture were more likely to be biopsied. History of malignancy, symptoms >1 week but <3 months, and atypical or change in architecture on US was associated with delayed biopsy. Patients with long-term follow-up (LTF) were followed for a median of 99.0 days. Malignancies were identified in 12 patients (2.1%). All malignancies were diagnosed within 14 days of presentation, and no malignancies were identified in LTF. CONCLUSIONS: Patients with persistent low suspicion lymphadenopathy are often followed for long durations; however, in this cohort, no malignancies were diagnosed during LTF. We propose an algorithm of forgoing a biopsy and employing primary care surveillance and education, which may be appropriate for these patients in the proper setting.

Social Media, Misinformation, and Online Patient Education in Emergency General Surgical Procedures.

INTRODUCTION: Patients use the internet to learn about diagnoses and treatment options. These sources vary in quality and accuracy of medical information. Thus, utilization of social media may lead to misinformation regarding treatment for patients in need of emergent general surgery procedures. METHODS: YouTube was searched with keywords "cholecystectomy," "cholecystitis," and "gallbladder surgery" and "appendectomy," "appendicitis," and "appendix surgery." For each procedure, the 100 videos with the greatest views were reviewed. Videos were assessed by four surgical trainees using validated instruments, DISCERN and the Patient Education Materials Assessment Tool (PEMAT), and Likert scales for patient education and misinformation. After appendectomy or cholecystectomy, patients completed a survey assessing use of social media preoperatively. RESULTS: The median DISCERN score was 28.0 of 75. The median PEMAT scores were 66.7% for understandability and 0% for actionability. Nearly half (49%) of videos provided no patient education and only 22% provided moderate or more. More than a third (35%) of videos contained misinformation. Doctors, medical education, and healthcare systems published videos with less misinformation, whereas patients, health/wellness groups published more misinformation (P < 0.001). Videos discoverable with colloquial terms "appendix surgery" and "gallbladder surgery" were more likely to contain misinformation (45.3%) compared to 20.5% of videos with misinformation discoverable using medical search terms only (P < 0.001). CONCLUSIONS: There is a range of video quality online with most videos of poor quality and provide little patient education. Understanding information available to patients online can tailor surgeon-patient discussions to combat misinformation and improve the informed consent process for patients.

Recovery of Skill Decay After COVID-19 Redeployments and Implications for Competency Attainment.

INTRODUCTION: The COVID-19 pandemic immediately interrupted procedural training. The lasting impact of reduced caseloads and service redeployments on procedural-resident training has been underexplored. This longitudinal study investigated the long-term perspectives of skill decay after short breaks in training and implications for ensuring resident competency attainment. METHODS: Web-based cross-sectional surveys distributed immediately after (June 2020) compared to 1 y after (July 2021) COVID-19 redeployments at two tertiary academic medical centers of an integrated health system in New York. Participants included general surgery, surgical subspecialty, and anesthesiology residents and faculty. RESULTS: Fifty-five residents and 33 faculty completed the survey. Ninety-point nine percent of residents and 36.4% of faculty were redeployed to COVID-ICUs. Sixty-three-point seven percent of residents and 75.0% of faculty reported a reduction in resident technical skills in the short-term, with significantly less (45.5% of residents and 21.2% of faculty) reporting persistent reduction in technical skill after 1 y (P = 0.001, P < 0.001). Seventy-five percent of residents and 100% of faculty were confident residents would be able to practice independently at the conclusion of their training. Sixty-five-point five percent of residents and 63.6% of faculty felt that residents experienced a durable improvement in critical care skills. Residents also reported a positive long-term impact on professional core competencies at 1 y. CONCLUSIONS: Longitudinal surveillance of residents after COVID-19 redeployments suggests washout of temporary skill decay and return of resident confidence upon resumption of traditional training. This may provide insight into the impact of other short-term training interruptions on resident skill and promote greater resident support upon training resumption to ensure competency attainment.

Disparities in care of pediatric, adolescent, and young adult patients with solid tumors: A systematic review.

BACKGROUND: Numerous studies have demonstrated a variety of social inequalities within pediatric and young adult patients with solid tumors. This systematic review examines and consolidates the existing literature regarding disparities in pediatric and young adult solid tumor oncology. PROCEDURE: A MeSH search was performed on the following databases: MEDLINE, PubMed, OvidSP Cochrane, Central, Embase, Cinhal, and Scopus. The systematic review was performed using Rayyan QCRI. RESULTS: Total 387 articles were found on the initial search, and 34 articles were included in final review. Twenty-seven studies addressed racial and ethnic disparities; 23 addressed socioeconomic disparities. Patients with Hispanic ethnicity, Black race, and lower socioeconomic status were more likely to present at later stages, have differences in treatments and higher mortality rates. CONCLUSION: This qualitative systematic review identified both racial and socioeconomic disparities in pediatric cancer patients across a variety of solid tumor types. Patients with Hispanic ethnicity, Black race, and lower socioeconomic status are associated with disparities in stage at presentation, treatment, and outcome. Characterization of existing disparities provides the evidence necessary to support changes at a systemic level.

Utilizing ultrasound in suspected necrotizing enterocolitis with equivocal radiographic findings.

BACKGROUND: To examine the use of abdominal ultrasound (AUS) as a diagnostic adjunct in the diagnosis of necrotizing enterocolitis (NEC) in cases where abdominal radiography (AXR) is equivocal in order to reduce unnecessary antibiotic use in neonates. METHODS: Retrospective study (2017-2019) of infants undergoing NEC evaluation with equivocal AXR findings (n = 54). Paired AXR and AUS were reviewed with respect to presence or absence of pneumatosis. Concordance of AUS findings with decision to treat for NEC was evaluated. RESULTS: Among 54 infants where AXR was equivocal, AUS demonstrated presence of pneumatosis in 22 patients (41%), absence of pneumatosis in 31 patients (57%), and was equivocal in 1 patient. All patients with pneumatosis on AUS were treated for NEC. Of 31 patients without pneumatosis on AUS, 25 patients (78%) were not treated for NEC. Patients without pneumatosis on AUS received a significantly shorter mean duration of antibiotics compared to those with pneumatosis (3.3 days (+/- 4.8 days) vs 12.4 days (+/- 4.7 days)); p < 0.001). Of those patients not treated, none required treatment within 1 week following negative AUS. CONCLUSION: AUS is a valuable tool for evaluating the presence or absence of pneumatosis in the setting of equivocal AXR. Absence of pneumatosis on AUS informs clinical decision making and reduces unnecessary treatment and antibiotic usage.

Operative Findings in Pediatric and Adolescent Patients With Presumed Adnexal Torsion.

INTRODUCTION: Clinical and radiographic findings often lead to diagnostic laparoscopy for presumed adnexal torsion (AT). To better understand the preoperative factors leading to AT, we evaluated the clinical course of patients with ultrasound findings concerning for AT to assess intraoperative AT rates and predictive factors for AT. METHODS: An institutional review board-approved retrospective review in two hospital centers over a period of 5 y was performed for females (4-18 y) with ultrasound (US) findings concerning for AT (n = 225). Preoperative clinical, radiographic, and intraoperative findings were assessed for patients with intraoperative AT versus for those without. RESULTS: The median age of patients was 14 y. Of those who went to the operating room (OR) (n = 113), AT was found in 57%. There was no difference between patients taken to the OR with or without AT regarding demographics or presentation. The presence of nausea/vomiting, tenderness, leukocytosis, lack of blood flow, or a mass/cyst >5 cm were found to be more likely in patients with AT than in those without. An ovarian volume ratio >15 was noted to be predictive of AT. Six patients initially discharged from the emergency department returned and went to the OR, two of which had AT, both with ovarian salvage. CONCLUSIONS: Limited data are available when counseling patients with presumed AT. We found the larger mean ovarian volume and an ovarian volume ratio >15 were predictive of AT. Despite this, 43% of patients taken to the OR did not have AT. This relatively high rate of not finding AT intraoperatively may be justified given the sequelae of missing AT.

Prenatal Recognition of Hepatopulmonary Fusion in Right-Sided Congenital Diaphragmatic Hernia for Successful Operative Planning.

INTRODUCTION: Hepatopulmonary fusion (HPF) is a rare anomaly specifically associated with right-sided congenital diaphragmatic hernia (CDH). Fewer than 50 cases of HPF have been reported, most at the time of surgery or postmortem with an associated high morbidity and mortality rate. Prenatal diagnosis and optimal management of these rare cases have not been established. CASE PRESENTATION: We present a case of HPF diagnosed prenatally by fetal ultrasound and magnetic resonance imaging allowing postnatal and intraoperative planning leading to successful HPF separation and repair of the CDH. DISCUSSION: The prenatal recognition allowed the use of preoperative computed tomography angiogram and right cardiac catheterization to plan the surgical approach. Intraoperative ultrasound confirmed abnormal vasculature associated with the HPF facilitating a successful complete HPF separation and CDH repair was performed. The patient survived and continues to do well on long-term follow-up. Prenatal recognition may help reduce the high morbidity and mortality associated with HPF.

Role of interferon regulatory factor 5 (IRF5) in tumor progression: Prognostic and therapeutic potential.

Canonically, the transcription factor interferon regulatory factor 5 (IRF5) is a key mediator of innate and adaptive immunity downstream of pathogen recognition receptors such as Toll-like receptors (TLRs). Hence, dysregulation of IRF5 function has been widely implicated in inflammatory and autoimmune diseases. Over the last few decades, dysregulation of IRF5 expression has been also reported in hematologic malignancies and solid cancers that support a role for IRF5 in malignant transformation, tumor immune regulation, clinical prognosis, and treatment response. This review will provide an in-depth overview of the current literature regarding the mechanisms by which IRF5 functions as either a tumor suppressor or oncogene, its role in metastasis, regulation of the tumor-immune microenvironment, utility as a prognostic indicator of disease, and new developments in IRF5 therapeutics that may be used to remodel tumor immunity.

Pediatric, Adolescent and Young Adult (AYA) Peritoneal and Pleural Mesothelioma: A National Cancer Database Review.

PURPOSE: Malignant peritoneal and pleural mesothelioma are rare in young patients, with a paucity of data regarding clinical characteristics and outcomes. We aimed to describe the clinical characteristics, treatment strategies, and outcomes for pediatric and adolescent/young adult (AYA) patients. METHODS: The National Cancer Database (NCDB) was queried for malignant peritoneal and pleural mesothelioma in pediatric and AYA patients (ages 0-39) from 2004 to 2019. Stratification was performed for pediatric (age 0-21) and young adult (age 22-39) patients. Chi-squared, multivariable cox regression, and Kaplan-Meier analyses were performed. RESULTS: We identified 570 total patients, 46 pediatric and 524 young adult, with mesothelioma (363 peritoneal and 207 pleural). There were significant differences in sex distribution as patients with peritoneal mesothelioma were more frequently female (63.1%). Patients with peritoneal mesothelioma were more likely to have radical surgery compared to pleural mesothelioma (56.7% v. 24.6%, respectively). A majority of patients with peritoneal and pleural mesothelioma received chemotherapy (66.4% and 61.4%, respectively). For peritoneal mesothelioma, surgical resection was associated with improved overall survival, whereas male sex, neoadjuvant chemotherapy, and radiation were associated with worse overall survival. For pleural mesothelioma, intraoperative chemotherapy was associated with improved overall survival, whereas Black race was associated with worse overall survival. Mean overall survival was greater for patients with peritoneal mesothelioma (125 months) compared to those with pleural mesothelioma (69 months), which remained significant after stratification of pediatric and young adult patients. CONCLUSION: By analyzing a large cohort of pediatric and AYA mesothelioma, this study highlights clinical, prognostic, and survival differences between peritoneal and pleural disease. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective.

IRF5 suppresses metastasis through the regulation of tumor-derived extracellular vesicles and pre-metastatic niche formation.

Metastasis is driven by extensive cooperation between a tumor and its microenvironment, resulting in the adaptation of molecular mechanisms that evade the immune system and enable pre-metastatic niche (PMN) formation. Little is known of the tumor-intrinsic factors that regulate these mechanisms. Here we show that expression of the transcription factor interferon regulatory factor 5 (IRF5) in osteosarcoma (OS) and breast carcinoma (BC) clinically correlates with prolonged survival and decreased secretion of tumor-derived extracellular vesicles (t-dEVs). Conversely, loss of intra-tumoral IRF5 establishes a PMN that supports metastasis. Mechanistically, IRF5-positive tumor cells retain IRF5 transcripts within t-dEVs that contribute to altered composition, secretion, and trafficking of t-dEVs to sites of metastasis. Upon whole-body pre-conditioning with t-dEVs from IRF5-high or -low OS and BC cells, we found increased lung metastatic colonization that replicated findings from orthotopically implanted cancer cells. Collectively, our findings uncover a new role for IRF5 in cancer metastasis through its regulation of t-dEV programming of the PMN.

Wounding patterns in pediatric firearm fatalities.

INTRODUCTION: Pediatric firearm injury became the leading cause of death among U.S. children in 2020. Studies evaluating wounding patterns in military and mass casualty shootings have provided insights into treatment and potential salvageability in adults, however, similar studies in the pediatric population do not exist. Hence, our study aimed to analyze wounding patterns of pediatric firearm fatalities and associated demographics and characteristics, such as place of death, to better understand pediatric firearm injuries, potential salvageability, and opportunities to reduce firearm deaths among vulnerable pediatric populations. METHODS: A retrospective review of the National Violent Death Reporting System from 2005-2017 was performed on patients 18 and younger. Mortalities were stratified by patient age: <12 years and 13-18 years and by intent- homicide, suicide, and unintentional. Comparative and exploratory analyses of demographics, location of death and anatomic location of wounds were performed. RESULTS: Of 8,527 pediatric firearm mortalities identified, 4,728 were homicides, 3,180 were suicides and 619 were unintentional injuries. Suicide victims were most likely to be dead on scene and >90% of suicide victims suffered head/neck injuries. For victims of homicide, younger children were more likely to die on scene (61% vs 44% p < 0.001). The pattern of injury in homicides differed for younger children compared to adolescents, with younger children with more head/neck injuries and older children more thoracic, thoracoabdominal, abdominal, and junctional injuries. In both age groups, children with extremity, abdominal and thoracoabdominal injuries were more likely to die later in the emergency department or inpatient setting. CONCLUSIONS: Wounding patterns across pediatric firearm mortalities in the U.S. vary by age and intent. The majority of pediatric firearm deaths were due to head/neck injuries. Children with homicide and unintentional deaths had more wounding pattern variation, including more injuries to the thorax and abdomen, and a much lower rate of dead-on scene than suicide victims. Our study of wounding patterns among U.S. children killed by firearms highlights the complexity of these injuries and offers opportunities for tailored public health strategies across varying vulnerable pediatric populations.

Surgical Rehabilitation for Research Residents: A Pilot Program to Offset Surgical Skill Decay.

OBJECTIVE: Select general surgery residents in the surgeon-scientist pipeline dedicate time away from clinical residency to conduct research. However, these research residents (RR) are vulnerable to operative skill decay. The aim of this study is to assess the feasibility of implementation and impact of an organized intervention designed to combat skill decay experienced by RR. DESIGN: RR were enrolled in a pilot Surgical Rehabilitation Program (SRP). The SRP is comprised of 12 cadaver-based simulation sessions and supplemented with Fundamentals of Laparoscopic Surgery-based simulation workouts. The RR were integrated with the clinical residents (CR) during the cadaver sessions and were subsequently performance tested, surveyed, and interviewed. SETTING: One academic general surgery residency program graduating 8 chief residents yearly in New York. PARTICIPANTS: General surgery CR and residents on dedicated research years. RESULTS: Data were collected for all local RR (n = 8) and 77% (n = 37) of CR. Local RR conducted research within the same health system that sponsors the residency. RR experienced gaps in training ranging from 2 to 4 years. All RR were permitted to moonlight on surgical services, however performed 0 operations and only 0.88 procedures on average per shift. Although RR performed similarly to level-matched CR on basic laparoscopic tasks, they required significantly more time on laparoscopic suturing-based skills than CR (p < 0.001). RR had significantly lower confidence levels precadaver sessions but gained confidence postcadaver sessions (p < 0.05), whereas CR confidence was unchanged. Regarding the SRP, qualitative interviews revealed major themes emphasizing the integration of RR, exposure to CR and faculty, technical skill development, maintenance of surgical know-how, and improved confidence for RR. CONCLUSIONS: The implementation of such structured interventions, like our SRP, aimed at supporting RR over gap years is essential to help residents maintain skills and confidence needed to achieve their goals of becoming surgeon scientists.

Trends and Disparities in Firearm Deaths Among Children.

BACKGROUND AND OBJECTIVES: In 2020, firearm injuries became the leading cause of death among US children and adolescents. This study aimed to evaluate new 2021 data on US pediatric firearm deaths and disparities to understand trends compared with previous years. METHODS: Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research was queried for firearm mortalities in children/adolescents from 2018 to 2021. Absolute mortality, death rates, and characteristics were reported. Death rates were defined per 100 000 persons in that population per year. Death rates across states were illustrated via geographic heat maps, and correlations with state poverty levels were calculated. RESULTS: In 2021, firearms continued to be the leading cause of death among US children. From 2018 to 2021, there was a 41.6% increase in the firearm death rate. In 2021, among children who died by firearms, 84.8% were male, 49.9% were Black, 82.6% were aged 15 to 19 years, and 64.3% died by homicide. Black children accounted for 67.3% of firearm homicides, with a death rate increase of 1.8 from 2020 to 2021. White children accounted for 78.4% of firearm suicides. From 2020 to 2021, the suicide rate increased among Black and white children, yet decreased among American Indian or Alaskan Native children. Geographically, there were worsening clusters of firearm death rates in Southern states and increasing rates in Midwestern states from 2018 to 2021. Across the United States, higher poverty levels correlated with higher firearm death rates (R = 0.76, P < .001). CONCLUSIONS: US pediatric firearm deaths increased in 2021, above the spike in 2020, with worsening disparities. Implementation of prevention strategies and policies among communities at highest risk is critical.

Hospital-Based Violence Intervention Programs to Reduce Firearm Injuries in Children: A Scoping Review.

INTRODUCTION: Hospital-based violence intervention programs (HVIPs) have shown promise in preventing reinjury and enhancing recovery from violent injuries, including those related to firearms. Historically, HVIPs have primarily focused on at-risk adolescents and young adults. The aim of this study is to perform a scoping review of HVIPs targeting children under the age of 18, describe the evidence supporting these programs, and deduce the potential impact of expanding HVIPs to younger children. METHODS: A scoping review was performed utilizing PubMed database with search terms "violence intervention program" and pediatric, or children, or youth. Articles were screened for youth-inclusive violence programs, and the literature was analyzed for program descriptions, evidence supporting interventions, and barriers to evaluation. RESULTS: 36 studies (covering 23 programs) were identified that met criteria (including patients ≤18 years old), with only 4 programs including children under 10. Many HVIPs utilize brief hospital interventions with longitudinal wraparound outpatient services. Despite heterogeneity in programs and studied outcomes, many HVIPs demonstrated positive outcomes, such as reduction of risk factors, decreased reinjury, decreased violent behaviors, decreased criminal justice involvement, and positive attitude or behavioral changes. Only a few studies reported increased odds of enrollment and positive impact in younger patients specifically. CONCLUSIONS: Children are an impressionable population in which HVIPs may have significant impact; however, there remains a gap in targeted programs. Given that firearm injuries are the leading cause of death in children and adolescents, priority should be given to piloting, implementing, and evaluating HVIPs among younger age groups. LEVEL OF EVIDENCE: Level IV.

A Survey of the Impact of the COVID-19 Crisis on Skill Decay Among Surgery and Anesthesia Residents.

OBJECTIVE: The SARS-CoV-2 (COVID-19) pandemic has profoundly impacted healthcare delivery and strained medical training. This study explores resident and faculty perceptions regarding the impact of the COVID-19 crisis on technical skill decay of surgical and anesthesia residents. We hypothesized that many residents perceived that their technical abilities diminished due to a short period of interruption in their training. DESIGN: An IRB-exempt, web-based cross-sectional survey distributed to residents and faculty SETTING: Two large academic tertiary medical centers, North Shore University Hospital and Long Island Jewish Medical Center, of the Northwell Health System in New York. PARTICIPANTS: General surgery, anesthesiology, plastic surgery, cardiothoracic surgery, orthopedic surgery, oral maxillofacial surgery, urology, podiatry residents and faculty. RESULTS: All residents reported a significant impact on their training. Residents (82%) and faculty (94%) reported a significant reduction in case volumes due to the COVID-19 pandemic (p < 0.05). 64% of residents reported a reduction in technical skills, and 75% of faculty perceived a decrease in resident technical skills. Residents were concerned about fulfilling ACGME case requirements, however faculty were more optimistic that residents would achieve level-appropriate proficiency by the conclusion of their training. Both residents and faculty felt that resident critical care skills improved as a result of redeployment to COVID-19 intensive care units (66% and 94%). Additionally, residents reported increased confidence in their ability to care for critically ill patients and positive impact on professional competencies. CONCLUSIONS: Effects of the COVID-19 pandemic on residency training are multi-dimensional. The majority of surgical and anesthesia residents perceived that their technical ability diminished as a result of skill decay, whereas other skillsets improved. Longitudinal surveillance of trainees is warranted to evaluate the effect of reduced operative volume and redeployment on professional competency.

Robotic Approach for Median Arcuate Ligament Release in Pediatrics.

Background: Median arcuate ligament (MAL) syndrome is a rare cause of chronic abdominal pain in adults and children. Release of the MAL has traditionally been performed open or laparoscopically. There have not been any published cases to our knowledge of robotic-assisted MAL release in pediatric patients. Patients and Methods: Two adolescent patients, aged 12 and 15 years, at our institution underwent robotic-assisted MAL release. The procedure involved dissecting the MAL muscle fibers and overlying scar tissue. Patients stayed inpatient postoperatively overnight and with an average outpatient follow-up of 10 months. Results: Both patients had immediate pain relief postoperatively and at 10-month follow-up had no recurrent symptoms. No complications were associated with the procedure. Conclusion: The increasing role of robotic surgery as a new surgical technique is gaining momentum for many procedures. This new approach for MAL release in the pediatric population was explored by our institution. It was found to be successful, safe, and reproducible for future patients.

The association between insurance status and diagnostic imaging for acute abdominal pain among emergency department patients in the United States, 2005-2014.

Introduction and objectives: Acute abdominal pain (AAP) is one of the most common complaints in the emergency department (ED). Rapid diagnosis is essential and is often achieved through imaging. Computed tomography (CT) is widely considered an exemplary test in the diagnosis of AAP in adult patients. As previous studies show disparities in healthcare treatment based on insurance status, our objective was to assess the association between insurance status and frequency of CT ordered for adult patients presenting to the ED with AAP from 2005 to 2014. Methods: This study used the National Hospital and Ambulatory Medical Care Survey: Emergency Department Record (NHAMCS) database, which collects data over a randomly assigned 4 week period in the 50 states and DC, to perform an observational retrospective analysis of patients presenting to the ED with AAP. Patients with Medicaid, Medicare or no insurance were compared to patients with private insurance. The association between insurance status and frequency of CT ordered was measured by obtaining odds ratios along with 95% CIs adjusted for age, gender and race/ethnicity. Results: Individuals receiving Medicaid are 20% less likely to receive CT than those with private insurance (OR 0.8, CI 0.6-0.99, p = .046). Those on Medicare or who are uninsured have no difference in odds of obtaining a CT scan compared to patients with private insurance. Additional findings are that black patients are 42% less likely to receive a CT scan than white patients. Conclusions and implications: Patients on Medicaid are significantly less likely to receive a CT when presenting to the ED with AAP. Differences in diagnostic care may correlate to inferior health outcomes in patients without private insurance.
