Long-term Outcomes Following Thoracoscopic Division of Vascular Rings.

OBJECTIVES: We evaluate long-term symptomatic improvement in vascular ring patients who underwent thoracoscopic division at a single quaternary pediatric surgery center. METHODS: All pediatric patients who underwent vascular ring division without Kommerell's diverticulum resection between 01/2007-12/2022 were included. Surgeries were performed by pediatric general and thoracic surgeons. Patient demographic and clinical characteristics were obtained from retrospective chart review. Data on long-term symptomatic improvement were collected with structured telephone interviews. RESULTS: 60% of patients were male. Median age at operation was 24 months (IQR: 11, 60 months) with a median weight of 11.3 kg (IQR: 8.7, 19.8 kg). All patients were symptomatic preoperatively with dysphagia being the most frequent complaint (42%), followed by chronic cough (21%). Of 41 patients eligible for the long-term follow-up survey, 8 patients with a primary diagnosis of a double arch with an atretic segment in the non-dominant arch and 9 with a right dominant arch with left ligamentum arteriosum and aberrant left subclavian artery (LSCA) were contacted and consented for participation. Median interval from surgery to survey completion was 95 months (IQR 28, 135 months). Most patients had no, or only minor, symptoms related to breathing and swallowing at the time of long-term follow-up. 88% of patients experienced postoperative symptom improvement, and only one patient reported worsening of symptoms over time. CONCLUSION: Division of an atretic arch and/or ligamentum for patients with an aberrant LSCA without Kommerell's resection may be adequate to ensure long-term improvement of breathing and swallowing problems attributable to vascular rings. LEVEL OF EVIDENCE: Level IV.

Modification of Firearm Law-Firearm Injury Association by Economic Disadvantage.

INTRODUCTION: Firearm-related injuries in the U.S. have risen 37% since 2015. Understanding how the association between firearm incidents and state-level firearm restrictiveness is modified by community-level distress and economic connectedness (EC) may inform upstream injury prevention efforts. METHODS: A national cross-sectional study of firearm incidents (interpersonal and unintentional firearm events) occurring between 1/2015 and 12/2021 was performed using the Gun Violence Archive. The exposures were community distress (Distressed Communities Index, DCI), EC, and year-state-level firearm restrictiveness. The primary outcome was mean annual urban firearm incidence rate per ZIP Code Tabulation Area. Generalized linear mixed models were fit to evaluate the modification of the firearm law-firearm incident association by DCI and EC. Data analyses took place in 2022. RESULTS: About 266,020 firearm incidents were included. The mean rate was higher with each DCI tertile, with a RR of 3.18 (95% CI: 3.06, 3.30) in high versus low distress communities. Low EC was associated with over 1.8 times greater rate of firearm-related injury. The least restrictive firearm laws were associated with 1.20 times higher risk of firearm incidents (95% CI: 1.12, 1.28). The association between restrictive laws and lower incidence rates was strongest in low and medium distress and high EC communities. CONCLUSIONS: Stricter firearm laws are associated with lower rate of firearm incidents. The magnitude of this association is smallest for communities experiencing the greatest economic disadvantage.

Community-Level Social Vulnerability and Patterns of Adolescent Injury.

Objective: To describe adolescent injuries by the community-level social vulnerability, focusing on injuries related to interpersonal violence. Background: The Center for Disease Control and Prevention's social vulnerability index (SVI) is a tool used to characterize community-level vulnerability. Methods: Injured adolescent trauma patients (13-17 years old) cared for at a large Level I trauma center over a 10-year period were identified. Injuries were classified by intent as either intentional or unintentional. Census tract level SVI was calculated by composite score and for 4 subindex scores (socioeconomic, household composition/disability, minority/language, housing type/transportation). Patients were stratified by SVI quartile with the lowest quartile designated as low-, the middle two quartiles as average-, and the highest quartile as high vulnerability. The primary outcome was odds of intentional injury. Demographic and injury characteristics were compared by SVI and intent. Multivariable logistic regression was used to estimate the adjusted odds of intentional injury associated with SVI. Results: A total of 1993 injured adolescent patients (1676 unintentional and 317 intentional) were included. The composite SVI was higher in the intentional injury cohort (mean, SD: 66.7, 27.8 vs. 50.5, 30.2; P < 0.001) as was each subindex SVI. The high SVI cohort comprised 31% of the study population, 49% of intentional injuries, and 51% of deaths. The high SVI cohort had significantly increased unadjusted (odds ratio, 4.5; 95% confidence interval, 3.0-6.6) and adjusted (odds ratio, 1.8; 95% confidence interval, 1.6-2.8) odds of intentional injury. Conclusions: Adolescents living in the highest SVI areas experience significantly higher odds of intentional injury. SVI and SVI subindex details may provide direction for community-level interventions to decrease the impact of violent injury among adolescents.

Can magnetic resonance imaging replace computed tomography scans in the evaluation of pediatric post-appendectomy abscess?

BACKGROUND: Computed tomography scans have been used when cross-axial imaging is required to evaluate pediatric post-appendectomy abscesses. To reduce a source of radiation exposure, our institution converted to using contrast-enhanced magnetic resonance imaging to replace computed tomography scans in this clinical context. Our aim is to evaluate the performance of magnetic resonance imaging compared to computed tomography scans and associated clinical outcomes in this patient population. METHODS: A contrast-enhanced comprehensive magnetic resonance imaging protocol was implemented to evaluate a post-appendectomy abscess in 2018. A retrospective chart review was performed from 2015 to 2022 for pediatric patients (<18 years old) with prior appendectomy and subsequent cross-sectional imaging to evaluate for an intraabdominal abscess. Patient characteristics and clinical parameters between the 2 modalities were abstracted and compared using standard univariate statistics. RESULTS: There were a total of 72 post-appendectomy patients who received cross-axial imaging, which included 43 computed tomography scans and 29 magnetic resonance imaging during the study interval. Patient demographics were comparable between cohorts and rates of perforated appendicitis at the index operation (computed tomography: 79.1% vs magnetic resonance imaging: 86.2%). Missed abscess rate, abscess size, management technique, drainage culture results, readmission, and reoperation were similar between imaging modalities. Median request to scan time was longer for magnetic resonance imaging than computed tomography (191.5 vs 108 minutes, P = .04). The median duration of a comprehensive magnetic resonance imaging scan was 32 minutes (interquartile range 28-50.5 minutes). CONCLUSION: Contrast-enhanced magnetic resonance imaging provides an alternative cross-sectional imaging modality to computed tomography scans to evaluate pediatric post-appendectomy abscesses.

Association of Community Vulnerability and State Gun Laws With Firearm Deaths in Children and Adolescents Aged 10 to 19 Years.

Importance: Firearm-related injuries are the leading cause of death among children and adolescents in the US. For youths aged 10 to 19 years, 64% of firearm-related deaths are due to assault. Understanding the association between the rate of death due to assault-related firearm injury and both community-level vulnerability and state-level gun laws may inform prevention efforts and public health policy. Objective: To assess the rate of death due to assault-related firearm injury stratified by community-level social vulnerability and state-level gun laws in a national cohort of youths aged 10 to 19 years. Design, Setting, and Participants: This national cross-sectional study used the Gun Violence Archive to identify all assault-related firearm deaths among youths aged 10 to 19 years occurring in the US between January 1, 2020, and June 30, 2022. Exposure: Census tract-level social vulnerability (measured by the Centers for Disease Control and Prevention social vulnerability index [SVI]; categorized in quartiles as low [<25th percentile], moderate [25th-50th percentile], high [51st-75th percentile], or very high [>75th percentile]) and state-level gun laws (measured by the Giffords Law Center gun law scorecard rating; categorized as restrictive, moderate, or permissive). Main Outcomes and Measures: Youth death rate (per 100 000 person-years) due to assault-related firearm injury. Results: Among 5813 youths aged 10 to 19 years who died of an assault-related firearm injury over the 2.5-year study period, the mean (SD) age was 17.1 (1.9) years, and 4979 (85.7%) were male. The death rate per 100 000 person-years in the low SVI cohort was 1.2 compared with 2.5 in the moderate SVI cohort, 5.2 in the high SVI cohort, and 13.3 in the very high SVI cohort. The mortality rate ratio of the very high SVI cohort compared with the low SVI cohort was 11.43 (95% CI, 10.17-12.88). When further stratifying deaths by the Giffords Law Center state-level gun law scorecard rating, the stepwise increase in death rate (per 100 000 person-years) with increasing SVI persisted, regardless of whether the Census tract was in a state with restrictive gun laws (0.83 in the low SVI cohort vs 10.11 in the very high SVI cohort), moderate gun laws (0.81 in the low SVI cohort vs 13.18 in the very high SVI cohort), or permissive gun laws (1.68 in the low SVI cohort vs 16.03 in the very high SVI cohort). The death rate per 100 000 person-years was higher for each SVI category in states with permissive compared with restrictive gun laws (eg, moderate SVI: 3.37 vs 1.71; high SVI: 6.33 vs 3.78). Conclusions and Relevance: In this study, socially vulnerable communities in the US experienced a disproportionate number of assault-related firearm deaths among youths. Although stricter gun laws were associated with lower death rates in all communities, these gun laws did not equalize the consequences on a relative scale, and disadvantaged communities remained disproportionately impacted. While legislation is necessary, it may not be sufficient to solve the problem of assault-related firearm deaths among children and adolescents.

The association between childhood opportunity index and pediatric hospitalization for firearm injury or motor vehicle crash.

BACKGROUND: Community-level factors can profoundly impact children's health, including the risk of violent injury. This study's objective was to understand the relationship between the Childhood Opportunity Index and pediatric firearm injury owing to interpersonal violence compared with a motor vehicle crash. METHODS: All pediatric patients (<18 years) who presented with an initial encounter with a firearm injury or motor vehicle crash between 2016 to 2021 were identified from 35 children's hospitals included in the Pediatric Health Information System database. The child-specific community-level vulnerability was determined by the Childhood Opportunity Index, a composite score of neighborhood opportunity level data specific to pediatric populations. RESULTS: We identified 67,407 patients treated for injuries related to motor vehicle crashes (n = 61,527) or firearms (n = 5,880). The overall cohort had a mean age of 9.3 (standard deviation 5.4) years; 50.0% were male patients, 44.0% non-Hispanic Black, and were 60.8% publicly insured. Compared with motor vehicle crash injuries, patients with firearm-related injuries were older (12.2 vs 9.0 years), more likely to be male patients (77.7% vs 47.4%), non-Hispanic Black (63.5% vs 42.1%), and had public insurance (76.4 vs 59.3%; all P < .001). In multivariable analysis, children living in communities with lower Childhood Opportunity Index levels were more likely to present with firearm injury than those living in communities with a very high Childhood Opportunity Index. The odds increased as the Childhood Opportunity Index level decreased (odds ratio 1.33, 1.60, 1.73, 2.00 for high, moderate, low, and very low Childhood Opportunity Index, respectively; all P ≤ .001). CONCLUSION: Children from lower-Childhood Opportunity Index communities are disproportionately impacted by firearm violence, and these findings have important implications for both clinical care and public health policy.

Fecal continence disparities in patients with idiopathic constipation treated at referral institutions for pediatric colorectal surgery.

PURPOSE: Fecal continence is a concern for many patients with idiopathic constipation and can significantly impact quality of life. It is unknown whether racial, ethnic, and socioeconomic disparities are seen in fecal continence within the idiopathic constipation population. We aimed to evaluate fecal continence and associated demographic characteristics in children with idiopathic constipation referred for surgical evaluation. METHODS: A multicenter retrospective study of children with idiopathic constipation was performed at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). All patients >3y of age with idiopathic constipation diagnosis were included. The primary outcome was fecal continence, categorized as complete (no accidents ever), daytime (no accidents during the day), partial (occasional incontinence day/night), and none (incontinent). We evaluated for associations between fecal continence and race, sex, age, insurance status, and other patient-level factors, employing Kruskal-Wallis and trend tests. RESULTS: 458 patients with idiopathic constipation from 12 sites were included. The median age of diagnosis was 4.1 years. Only 25% of patients referred for surgical evaluation were completely continent. Age at the visit was significantly associated with fecal continence level (p = 0.002). In addition, patients with public and mixed public and private insurance had lower levels of continence (p<0.001). Patients with developmental delay were also more likely to have lower continence levels (p = 0.009) while diagnoses such as anxiety, ADD/ADHD, autism, depression, obsessive-compulsive disorder were not associated. Approximately 30% of patients had an ACE operation (antegrade continence enema) at a median age of 9.2 years at operation. Black patients were significantly less likely to undergo ACE operation (p = 0.016) when compared to white patients. CONCLUSION: We observed data that suggest differences in fecal incontinence rates based on payor status. Further investigation is needed to characterize these potential areas of disparate care. LEVEL OF EVIDENCE: Level III.

Interpersonal violence affecting the pediatric population: Patterns of injury and recidivism.

PURPOSE: We aim to describe interpersonal violence-related injury patterns in the pediatric trauma population and to identify predictors of recidivism. METHODS: In this retrospective analysis from a single institution, we included pediatric patients (≤17 years) treated (2006-2020) for traumatic injury related to interpersonal violence (IPV). Patient characteristics were compared among mechanism types and between recidivists and non recidivists using two sample t-tests, Wilcoxon rank-sum tests, and Pearson's chi-squared. Multivariate analysis was performed using logistic regression to identify predictors of repeat injury. RESULTS: We identified 635 pediatric patients who sustained injuries owning to IPV: firearm (N = 266), assault (stab/blunt; N = 243), and abuse (N = 126). The average age of the firearm, assault, and abuse groups was 15.5, 14.7, and 1.1 years (SD = 2.2, 3.4, 2.4 years), respectively. Majority of the overall cohort was male (77.5%) and publicly- or un insured (67.8%), with 28.0% being Black. Of the 489 firearm and assault patients who survived the first injury, 30 (6.1%) had repeat injury owning to IPV requiring treatment at our center with a median time of 40 months (IQR 17-62 months) between first and second injury. The majority of recidivists (83.3%) were victims of gun violence whereas the distribution between assault and firearm in the non recidivists was more even at 51 and 49%, respectively (p < 0.001). Eighteen (60.0%) of the recidivist patients had the same mechanism between the first and second injury. In the logistic regression analysis, Black race and firearm injury were associated with greater than 3-fold higher likelihood of repeat injury compared to white race after adjusting for age, sex, insurance, and child opportunity index. CONCLUSIONS: We found that survivors of firearm injuries and assault comprise a vulnerable patient cohort at risk for repeat injury, and Black race is an independent predictor of repeat injury owning to IPV. These findings provide guidance for developing violence prevention programs. TYPE OF STUDY: Retrospective Comparative Study LEVEL OF EVIDENCE: Level III.

Risk factors of perioperative mortality from complicated peptic ulcer disease in Africa: systematic review and meta-analysis.

Introduction: In 2013, peptic ulcer disease (PUD) caused over 300 000 deaths globally. Low-income and middle-income countries are disproportionately affected. However, there is limited information regarding risk factors of perioperative mortality rates in these countries. Objective: To assess perioperative mortality rates from complicated PUD in Africa and associated risk factors. Design: We performed a systematic review and a random-effect meta-analysis of literature describing surgical management of complicated PUD in Africa. We used subgroup analysis and meta-regression analyses to investigate sources of variations in the mortality rates and to assess the risk factors contributing to mortality. Results: From 95 published reports, 10 037 patients underwent surgery for complicated PUD. The majority of the ulcers (78%) were duodenal, followed by gastric (14%). Forty-one per cent of operations were for perforation, 22% for obstruction and 9% for bleeding. The operations consisted of vagotomy (38%), primary repair (34%), resection and reconstruction (12%), and drainage procedures (6%). The overall PUD mortality rate was 6.6% (95% CI 5.4% to 8.1%). It increased to 9.7% (95% CI 7.1 to 13.0) when we limited the analysis to studies published after the year 2000. The correlation was higher between perforated PUD and mortality rates (r=0.41, p<0.0001) than for bleeding PUD and mortality rates (r=0.32, p=0.001). Non-significant differences in mortality rates existed between sub-Saharan Africa (SSA) and North Africa and within SSA. Conclusion: Perioperative mortality rates from complicated PUD in Africa are substantially high and could be increasing over time, and there are possible regional differences.

Pain and Dysfunction with Sexual Activity after Inguinal Hernia Repair: Systematic Review and Meta-Analysis.

BACKGROUND: The reported incidence rates of sexual dysfunction (SD) and pain with sexual activity (PSA) after inguinal hernia repair in males vary considerably. This meta-analysis explores the rates of SD and PSA after different surgical and anesthesia types to understand patient risk after inguinal hernia repair. STUDY DESIGN: We performed a systematic review and meta-analysis using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines to search 3 databases (EMBASE, MEDLINE, and Cochrane Library). We identified retrospective, prospective, and randomized controlled trial studies, published on or before March 1, 2019, reporting on SD and PSA after inguinal hernia repair. We used random-effects models to calculate pooled estimates of incidence rates of SD and PSA after inguinal hernia repair. Subgroup meta-analyses and meta-regression were used to explore sources of variation. RESULTS: A total of 4,884 patients from 12 studies were identified. Study-level median age at the time of repair was 52.3 years old, and study-level median follow-up was 10.5 months. Definitions of SD and PSA focused on completion of intercourse for the former and pain with erection/ejaculation for the latter. The overall incidence of new-onset, postoperative SD was 5.3% (95% CI 3.6% to 7.9%) and of PSA was 9.0% (95% CI 5.8% to 13.6%). Rates of SD associated with minimally invasive surgical (MIS) and open repair were, respectively, 7.8% (95% CI 5.4% to 11.3%) and 3.7% (95% CI 2.0% to 6.8%); rates of PSA were 7.4% (95% CI 4.7% to 11.5%) and 12.5% (95% CI 6.4% to 23.3%), respectively. CONCLUSIONS: Sexual dysfunction and PSA are not rare after inguinal hernia repair. They should be included in preoperative discussions and as standard metrics in reporting outcomes of repair in large cohorts or trials.

Regional, racial, gender, and tumor biology disparities in breast cancer survival rates in Africa: A systematic review and meta-analysis.

BACKGROUND: The survival rates from breast cancer in Africa are poor and yet the incidence rates are on the rise. In this study, we hypothesized that, in Africa, a continent with great disparities in socio-economic status, race, tumor biology, and cultural characteristics, the survival rates from breast cancer vary greatly based on region, tumor biology (hormone receptor), gender, and race. We aimed to conduct the first comprehensive systematic review and meta-analysis on region, gender, tumor-biology and race-specific 5-year breast cancer survival rates in Africa and compared them to 20-year survival trends in the United States. METHODS: We searched MEDLINE, EMBASE, and Cochrane Library to identify studies on breast cancer survival in African published before October 17, 2018. Pooled 5-year survival rates of breast cancer were estimated by random-effects models. We explored sources of heterogeneity through subgroup meta-analyses and meta-regression. Results were reported as absolute difference (AD) in percentages. We compared the survival rates of breast cancer in Africa and the United States. FINDINGS: There were 54 studies included, consisting of 18,970 breast cancer cases. There was substantial heterogeneity in the survival rates (mean 52.9%, range 7-91%, I2 = 99.1%; p for heterogeneity <0.0001). Meta-regression analyses suggested that age and gender-adjusted 5-year survival rates were lower in sub-Saharan Africa compared to north Africa (AD: -25.4%; 95% CI: -34.9 - -15.82%), and in predominantly black populations compared to predominantly non-black populations (AD: -25.9%; 95% CI: 35.40 - -16.43%). Survival rates were 10 percentage points higher in the female population compared to male, but the difference was not significant. Progesterone and estrogen receptor-positive breast cancer subtypes were positively associated with survival (r = 0.39, p = 0.08 and r = 0.24, p = 0.29 respectively), but triple-negative breast cancer was negatively associated with survival. Survival rates are increasing over time more in non-black Africans (55% in 2000 versus 65% in 2018) compared to black Africans (33% in 2000 versus 40% in 2018); but, the survival rates for Africans are still significantly lower when compared to black (76% in 2015) and white (90% in 2015) populations in the United States. CONCLUSION: Regional, sub-regional, gender, and racial disparities exist, influencing the survival rates of breast cancer in Africa. Therefore, region and race-specific public health interventions coupled with prospective genetic studies are urgently needed to improve breast cancer survival in this region.
