- Berisha, V., Wang, S., LaCross, A., Liss, J., & Garcia-Filion, P. (2017). Longitudinal changes in linguistic complexity among professional football players. Brain and language, 169, 57-63.More infoReductions in spoken language complexity have been associated with the onset of various neurological disorders. The objective of this study is to analyze whether similar trends are found in professional football players who are at risk for chronic traumatic encephalopathy. We compare changes in linguistic complexity (as indexed by the type-to-token ratio and lexical density) measured from the interview transcripts of players in the National Football League (NFL) to those measured from interview transcripts of coaches and/or front-office NFL executives who have never played professional football. A multilevel mixed model analysis reveals that exposure to the high-impact sport (vs no exposure) was associated with an overall decline in language complexity scores over time. This trend persists even after controlling for age as a potential confound. The results set the stage for a prospective study to test the hypothesis that language complexity decline is a harbinger of chronic traumatic encephalopathy.

Hormone research in paediatrics, 88(3-4), 251-257.More infoOptic nerve hypoplasia (ONH), a leading cause of pediatric blindness, is associated with brain malformations and hypopituitarism in the constellation known as septo-optic dysplasia. Neuroimaging is used to anticipate hypopituitarism, but with unconfirmed reliability. We report prospective findings on the association of hypopituitarism with brain malformations.

- Magoteaux, S., Gilbert, M., Langlais, C. S., Garcia-Filion, P., & Notrica, D. M. (2016). Should Children with Suspected Nonaccidental Injury Be Admitted to a Surgical Service?. Journal of the American College of Surgeons, 222(5), 838-43.More infoIn many hospitals, children with suspected nonaccidental trauma (sNAT) are admitted to nonsurgical services (NSS). Although the surgical service (SS) initially admitted sNAT patients at our American College of Surgeons (ACS)-verified level 1 pediatric trauma center (vPTC), a change in hospital policy allowed admission to NSS. The objective of this study was to determine if the rate of care-related indicators (CRIs) varies by admission to an SS vs an NSS in the sNAT patient population.
- Stewart, C., Garcia-Filion, P., Fink, C., Ryabets-Lienhard, A., Geffner, M. E., & Borchert, M. (2016). Efficacy of growth hormone replacement on anthropometric outcomes, obesity, and lipids in children with optic nerve hypoplasia and growth hormone deficiency. International journal of pediatric endocrinology, 2016, 5.More infoHypopituitarism and obesity are causes of major lifelong morbidity in patients with optic nerve hypoplasia (ONH). Growth hormone deficiency (GHD) affects the majority of children with ONH, though the degree of deficiency and variability of early growth patterns range from early severe retardation to normal initial growth. The utility of early GH replacement for improving anthropometric, body composition, and lipid outcomes in patients with ONH and GHD, especially those with normal initial height velocity, is unknown. This study examines the effects of GH replacement in a cohort of children with ONH and GHD.

Computed tomography vs magnetic resonance imaging for identifying acute lesions in pediatric traumatic brain injury. Hospital pediatrics, 5(2), 79-84.More infoPediatric traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Computed tomography (CT) is the modality of choice to screen for brain injuries. MRI may provide more clinically relevant information. The purpose of this study was to compare lesion detection between CT and MRI after TBI.

Pediatric critical care medicine : a journal of the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies, 16(2), 167-74.More infoChanges in technology and increased reports of successful extracorporeal life support use in patient populations, such as influenza, cardiac arrest, and adults, are leading to expansion of extracorporeal life support. Major limitations to extracorporeal life support expansion remain bleeding and thrombosis. These complications are the most frequent causes of death and morbidity. As a pilot project to provide baseline data for a detailed evaluation of bleeding and thrombosis in the current era, extracorporeal life support patients were analyzed from eight centers in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Collaborative Pediatric Critical Care Research Network.

Documenta ophthalmologica. Advances in ophthalmology, 131(1), 25-34.More infoPattern electroretinograms (PERGs) have inherently low signal-to-noise ratios and can be difficult to detect when degraded by pathology or noise. We compare an objective system for automated PERG analysis with expert human interpretation in children with optic nerve hypoplasia (ONH) with PERGs ranging from clear to undetectable.

Nonoperative management of blunt liver and spleen injury in children: Evaluation of the ATOMAC guideline using GRADE. The journal of trauma and acute care surgery, 79(4), 683-93.More infoNonoperative management of liver and spleen injury should be achievable for more than 95% of children. Large national studies continue to show that some regions fail to meet these benchmarks. Simultaneously, current guidelines recommend hospitalization for injury grade + 2 (in days). A new treatment algorithm, the ATOMAC guideline, is in clinical use at many centers but has not been prospectively validated.

Journal of pediatric surgery, 49(2), 330-2.More infoAlcohol use is a risk factor for adult trauma. Alcohol may significantly influence pediatric trauma risk, but literature is sparse. The aim of this study was to examine the impact of alcohol use screening in pediatric trauma patients.
- Lettieri, C. K., Garcia-Filion, P., & Hingorani, P. (2014). Incidence and outcomes of desmoplastic small round cell tumor: results from the surveillance, epidemiology, and end results database. Journal of cancer epidemiology, 2014, 680126.More infoDesmoplastic small round cell tumor (DSRCT) is a rare but highly fatal malignancy. Due to the rarity of this neoplasm, no large population based studies exist. Procedure. This is a retrospective cohort analysis. Incidence rates were calculated based on sex and ethnicity and compared statistically. Gender-, ethnicity-, and treatment- based survival were calculated using the Kaplan-Meier method. Results. A total of 192 cases of DSRCT were identified. Peak incidence age was between 20 and 24 years. Age-adjusted incidence rate for blacks was 0.5 cases/million and for whites was 0.2 cases/million (P = 0.037). There was no statistically significant difference in survival based on gender or ethnicity. When adjusted for age, there was no statistically significant difference in survival amongst patients who received radiation therapy compared to those who did not (HRadj = 0.73; 95% CI 0.49, 1.11). There was a statistically significant survival advantage for patients who received radiation after surgery compared to those who did not (HR 0.49; 95% CI 0.30, 0.79). Conclusion. DSRCT is more common in males and in people of African-American descent. Although overall survival remains poor, radiation therapy following surgery seems to improve outcome in these patients.

The journal of trauma and acute care surgery, 75(6), 1006-11; discussion 1011-2.More infoBlunt cerebrovascular injury (BCVI) has been well described in the adult trauma literature. The risk factors, proper screening, and treatment options are well known. In pediatric trauma, there has been very little research performed regarding this injury. We hypothesize that the incidence of BCVI in children is lower than the 1% reported incidence in adult studies and that many children at risk are not being screened properly.
