RESUMEN
BACKGROUND: A dose-response relationship between proportions of donor human milk (DHM) intake and in-neonatal intensive care unit (in-NICU) growth rates, if any, remains poorly defined. Objective was to evaluate interrelationships between percentages of DHM, mother's own milk (MOM), and preterm formula (PF) intake and neonatal growth parameters at 36 weeks postmenstrual age or NICU discharge. METHODS: Infants eligible for this single-center retrospective study were inborn at ≤32 weeks gestation or ≤1800âg, stayed in the NICU for ≥7 days, and received enteral nutrition consisting of human milk fortified with Enfamil human milk fortifier acidified liquid. Study exposures were defined as 10% increments in the total volumetric proportions of infant diet provided as MOM, DHM, or PF. Outcomes were growth parameters at 36 weeks postmenstrual age or NICU discharge. Multivariable linear regression modeled the adjusted additive effect of infant diet on individual growth parameters. RESULTS: A total of 314 infants records were eligible for analysis. Using MOM as reference, the adjusted mean growth velocity for weight significantly decreased by 0.17âgâ·âkgâ·âday for every 10% increase in DHM intake, but did not vary with PF intake. The adjusted mean change in weight z score significantly decreased with increasing proportion of DHM intake but significantly improved with increasing PF intake. The adjusted mean head circumference velocity was significantly decreased by 0.01âcm/wk for every 10% increase in DHM intake, in reference to MOM, but did not vary with PF intake. Neither proportion of DHM nor PF intake was associated with length velocity. CONCLUSIONS: When DHM and MOM are fortified interchangeably, preterm infants receiving incremental amounts of DHM are at increased risk of postnatal growth restriction. The dose-response relationship between DHM, MOM, and PF and long-term growth and neurodevelopmental outcomes warrants further research.

OBJECTIVE: To quantify optimal minimum durations of exclusive breastfeeding associated with maintenance of any breastfeeding at 15 time points during the first year of life. STUDY DESIGN: Mothers (n = 1189) from the prospective Infant Feeding Practices Study II cohort who initiated exclusive breastfeeding with healthy term infants were included. In a 80:20 split-sample validation study, receiver operating characteristic curves estimated optimal minimum durations of exclusive breastfeeding needed to predict maintenance of any breastfeeding at 15 time points during the first year (n = 951). Logistic regression estimated the predictive performance of the identified thresholds adjusted for maternal age, race, education, parity, support system, and return-to-work status. Results were validated in the remaining 20% (n = 238). RESULTS: Optimal minimum durations ranged from 4.0-17.1 weeks of exclusive breastfeeding associated with maintenance of any breastfeeding at 15 time points. All estimated threshold durations were statistically significant after adjustment. CONCLUSIONS: Using a methodological approach unique to breastfeeding duration research, the authors report optimal durations of exclusive breastfeeding associated with duration of any breastfeeding at time points throughout the first year. Perinatal clinicians, pediatricians, lactation professionals, policymakers, researchers, and families might apply these findings to achieve desirable collective breastfeeding duration outcomes.

PURPOSE: Surgical outcomes data for patent ductus arteriosus (PDA) ligation come primarily from single institution case series. The purpose of this study was to evaluate national PDA ligation trends, and to compare outcomes between pediatric general (GEN) and pediatric cardiothoracic (CT) surgeons. METHODS: The Pediatric Health Information System database was queried to identify neonates who underwent PDA ligation from 2006 through 2009. Outcomes evaluated included surgical morbidity, in-hospital mortality, length of stay, and total charges. Outcomes were compared between pediatric general and pediatric cardiothoracic surgeons. RESULTS: The records of 1,482 neonates who underwent PDA ligation were identified and analyzed. Overall mean gestational age was 26 ± 3 weeks and birth weight was 888 ± 428 g. The majority of patients among both surgeons had birth weights of ≤1,000 g (77.2%) and were born at ≤27-week gestation (81.5%). Most of the PDA ligations were performed by pediatric CT surgeons (n = 1,196, 80.7%). The mortality rate did not differ by surgeon subspecialty training (GEN = 5.2%, CT 7.9%, p = 0.16). Neonates in the cardiothoracic surgeon cohort showed lower length of stay (p < 0.001-0.05) and total hospital charges (p < 0.05) among patients with birth weight ≤1,200 g. Proxy measures of surgical morbidity-gastrostomy, fundoplication, and tracheostomy-showed no significant differences between the two surgical subspecialists overall or across birth weight subgroups (p > 0.05). CONCLUSION: These data provide a contemporary snapshot of PDA ligation outcomes at American children's hospitals. Pediatric general surgeons achieve comparable outcomes performing PDA ligation compared to pediatric cardiothoracic surgeons.

Objective The McGill Thyroid Nodule Score (MTNS) is a preoperative tool used to predict the risk for well-differentiated thyroid cancer given a specific nodule in adults. We evaluated the clinical utility of a modified pediatric MTNS with children and adolescents. Study Design Case series with chart review. Setting Tertiary care children's hospital. Subjects and Methods This is a retrospective chart review of 46 patients ≤18 years of age presenting with a solitary or dominant thyroid nodule treated with surgical resection between September 2008 and December 2015. The cumulative MTNS for each nodule was calculated and compared with the final pathology. Results Of 46 patients, 10 (21.7%) were diagnosed with well-differentiated thyroid cancer (80% papillary thyroid carcinoma, 10% follicular variant of papillary thyroid carcinoma, 10% follicular thyroid carcinoma). Malignant nodules were associated with a greater mean MTNS (benign, 5.72 ± 3.03; malignant, 16 ± 3.13; P < .05). The sensitivity, specificity, and positive predictive value of malignancy were 100%, 94.4%, and 83.3% for scores ≥10 and 80%, 100%, and 100% for scores ≥11, respectively. In nodules with indeterminate cytology (Bethesda III and IV), the pediatric MTNS showed good differentiation between benign and malignant disease, with mean scores of 7.95 and 12.5, respectively ( P = .006). Conclusion This pilot study suggests that a comprehensive scoring system may help assess the risk of malignancy in pediatric thyroid nodules and differentiate nodules with indeterminate cytology into higher- and lower-risk categories. Given these findings, larger, multi-institutional studies are warranted.

BACKGROUND: In the United States, there is a perceived divide regarding the benefits and risks of firearm ownership. The American College of Surgeons Committee on Trauma Injury Prevention and Control Committee designed a survey to evaluate Committee on Trauma (COT) member attitudes about firearm ownership, freedom, responsibility, physician-patient freedom and policy, with the objective of using survey results to inform firearm injury prevention policy development. METHODS: A 32-question survey was sent to 254 current U.S. COT members by email using Qualtrics. SPSS was used for χ exact tests and nonparametric tests, with statistical significance being less than 0.05. RESULTS: Our response rate was 93%, 43% of COT members have firearm(s) in their home, 88% believe that the American College of Surgeons should give the highest or a high priority to reducing firearm-related injuries, 86% believe health care professionals should be allowed to counsel patients on firearms safety, 94% support federal funding for firearms injury prevention research. The COT participants were asked to provide their opinion on the American College of Surgeons initiating advocacy efforts and there was 90% or greater agreement on 7 of 15 and 80% or greater on 10 of 15 initiatives. CONCLUSION: The COT surgeons agree on: (1) the importance of formally addressing firearm injury prevention, (2) allowing federal funds to support research on firearms injury prevention, (3) retaining the ability of health care professionals to counsel patients on firearms-related injury prevention, and (4) the majority of policy initiatives targeted to reduce interpersonal violence and firearm injury. It is incumbent on trauma and injury prevention organizations to leverage these consensus-based results to initiate prevention, advocacy, and other efforts to decrease firearms injury and death. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level I; therapeutic care, level II.

INTRODUCTION: Current literature strongly recommends ovarian preservation for pediatric patients with ovarian torsion. The purpose of this study was to evaluate national trends in the surgical management of pediatric ovarian torsion and to compare outcomes between pediatric surgeons (PED) and gynecologists (GYN). METHODS: We queried Pediatric Health Information System (PHIS) data from 2007 to 2011 for patients <18years old with a diagnosis of ovarian torsion who underwent a surgical procedure. Patients with malignant disease were excluded. Outcomes were compared between pediatric surgeons and gynecologists. RESULTS: A total of 1151 patients were identified with a mean age of 10.7±4.1years with a bimodal distribution. Pediatric surgeons performed the majority of procedures (81%) and were more likely to use a laparoscopic approach (PED 27% vs. GYN 17%, p<.05). Pediatric surgeons were more likely to perform an oophorectomy (PED 38% vs. GYN 27%, p<.01), and more likely to administer antibiotics for this clean procedure (PED 61% vs. GYN 29%, p<.001). The overall reoperation rate was 5.1% and did not differ significantly by subspecialty (PED 4.4% vs. GYN 7.8%, p>.05). CONCLUSIONS: These data demonstrate a significant opportunity for pediatric surgeons and gynecologists to improve ovarian salvage rates and to reduce unnecessary antibiotic utilization for children with ovarian torsion.

BACKGROUND: Treatment recommendations for Meckel's diverticulum (MD) come mostly from single-institution case series. The objective of this study was to review the surgical management and outcomes of children undergoing Meckel's diverticulectomy using contemporary data from a national database. METHODS: We queried 2007 to 2008 data from the Pediatric Health Information System database and analyzed demographic and outcome variables for patients undergoing surgical resection of MD. Cases were classified as primary (symptomatic MD) or secondary (incidental MD). Outcomes in primary cases were compared between open and laparoscopic approaches. Statistical analyses were performed using SPSS (Chicago, IL). RESULTS: Eight hundred fifteen children underwent Meckel's diverticulectomy. Meckel's diverticulectomy was more common in boys (boy-girl, 2.3:1), and half (53%) of the children required surgery before their fourth birthday. More cases (n = 485; 60%) were classified as primary, and most children were approached by laparotomy (75%). The most common presentations for primary cases were obstruction (30%), bleeding (27%), and intussusception (19%). In the primary group, patients treated with the laparoscopic approach had a shorter length of stay (open approach, 5.7 ± 5.2 days; laparoscopic approach, 4.3 ± 2.7 days; P < .02). CONCLUSION: These data describe current trends in the surgical treatment of MD in the United States. Laparoscopic Meckel's diverticulectomy appears to shorten length of stay but is used much less frequently than the traditional open approach.

INTRODUCTION: The purpose of this study was to compare laparoscopic and open pyloromyotomy using data from multiple centers in the United States. METHODS: Children's hospitals that have a predominant surgical approach to pyloromyotomy were identified in the Pediatric Health Information System database. Using 2005 data, institutions were stratified into open (OPEN) and laparoscopic (LAP) groups. Patients with significant comorbid conditions were excluded. Group differences were compared using t tests and Mann-Whitney nonparametric tests for continuous variables and exact tests for categorical variables. RESULTS: A total of 3 hospitals were in the LAP group (n = 207), and 4 hospitals were in the OPEN group (n = 357). The LAP group had a longer mean length of stay (LAP = 2.5 +/- 1.7, OPEN = 2.1 +/- 1.4 days; P = .02). Mean total hospital charges were similar in both groups (LAP = $11307 +/- 9499, OPEN = $11245 +/- 4841; P = .93), but there was significant skewness of the distribution for the LAP group. Nonparametric analysis demonstrated a statistically significant difference in charges (LAP median = $9727, min = $5075, max = $94323, OPEN median = $10001, min = $1614, max = $46461; P = .004). Four patients in the LAP group had charges ranging from approximately $56000 to $94000, which may have resulted from surgical complications. CONCLUSION: Prolonged length of stay and skewed hospital charge data in patients undergoing laparoscopic pyloromyotomy may be the result of rare but serious complications associated with the laparoscopic approach.

BACKGROUND: Several clinical asthma scores have been derived from combinations of physical findings in pediatric asthmatic patients. OBJECTIVE: To test the reproducibility and validity of one such score, the Modified Pulmonary Index Score (MPIS), and to evaluate its predictive value in children hospitalized for asthma. METHODS: In the MPIS, 6 categories are evaluated: oxygen saturation, accessory muscle use, inspiratory to expiratory flow ratio, degree of wheezing, heart rate, and respiratory rate. For each of these 6 measurements or observations, a score of 0 to 3 is assigned. To evaluate the reproducibility of the MPIS, inpatients with status asthmaticus were examined by an attending physician, nurse, and respiratory therapist who were blinded to the other observers' scores. To evaluate the validity of the MPIS as a scale of severity of illness in asthmatic patients, the score at admission was compared with selected outcomes in the same patients. RESULTS: A total of 30 patients participated in this study (mean +/- SD age, 7.6 +/- 5.5 years). Our finding revealed that the MPIS is highly reproducible with a high degree of interrater reliability across caregiver groups (physician to nurse: r = 0.98; 95% confidence interval [CI], >0.96; physician to respiratory therapist: r = 0.95; 95% CI, >0.92; nurse to respiratory therapist: r = 0.94; 95% CI, >0.90). The admission MPIS positively correlated with intensive care unit admission (P < .001), days of continuous albuterol therapy (P = .002), days of supplemental oxygen (P = .002), and length of hospital stay (P = .004). CONCLUSIONS: The MPIS is a highly reproducible and valid indicator of severity of illness in children with asthma. To our knowledge, this is the first pediatric clinical asthma score demonstrated to be reproducible across groups of health care professionals who treat pediatric patients with asthma.
