Exploring Views and Professional Learning Needs of Comprehensive, Integrated, Three-Tiered (Ci3T) Leadership Teams Related to Universal Behavior Screening Implementation.

Research conducted to date has highlighted barriers to initial adoption of universal behavior screening in schools. However, little is known regarding the experiences of those implementing these procedures and there have been no studies conducted examining the experiences of educators in different stages of implementing various tiered systems of supports. Universal screening is foundational to a successful Comprehensive, Integrated Three-Tiered (Ci3T) model of prevention-an integrated tiered system addressing academics, behavior, and social and emotional well-being.

Hydrocephalus in Spina Bifida.

Hydrocephalus is the most important co-morbidity in myelomeningocele from a neurosurgical perspective. Historically, 75-80% of patients with myelomeningocele have required treatment with a shunt but recent advances including intra-uterine myelomeningocele closure and ETV-CPC are reducing this burden. The expression of hydrocephalus differs between patients and across the life span.

Socioeconomic and demographic factors in the diagnosis and treatment of Chiari malformation type I and syringomyelia.

Objective: The goal of this study was to assess the social determinants that influence access and outcomes for pediatric neurosurgical care for patients with Chiari malformation type I (CM-I) and syringomyelia (SM).

Methods: The authors used retro- and prospective components of the Park-Reeves Syringomyelia Research Consortium database to identify pediatric patients with CM-I and SM who received surgical treatment and had at least 1 year of follow-up data. Race, ethnicity, and insurance status were used as comparators for preoperative, treatment, and postoperative characteristics and outcomes.

Impact of ventricle size on neuropsychological outcomes in treated pediatric hydrocephalus: an HCRN prospective cohort study.

Objective: In pediatric hydrocephalus, shunts tend to result in smaller postoperative ventricles compared with those following an endoscopic third ventriculostomy (ETV). The impact of the final treated ventricle size on neuropsychological and quality-of-life outcomes is currently undetermined. Therefore, the authors sought to ascertain whether treated ventricle size is associated with neurocognitive and academic outcomes postoperatively.

Project ENHANCE: Assessing Professional Learning Needs for Implementing Comprehensive, Integrated, Three-Tiered (Ci3T) Models of Prevention.

Unlabelled: We report findings from a multistate survey of 720 faculty and staff from 25 elementary schools in five districts across three states and geographic regions participating in an IES Network grant examining integrated tiered systems. In this preregistered study, we replicated and extended previous inquiry examining educators' views of (1) implementation of core components of their school's Comprehensive, Integrated, Three-Tiered (Ci3T) model of prevention; and (2) preference for professional learning (content and avenue). Results indicated more than half of respondents indicated high levels of implementation of core features of Ci3T across Tiers 1, 2, and 3.

Improving Educators' Knowledge, Confidence, and Usefulness of a Comprehensive, Integrated, Three-tiered (Ci3T) Model of Prevention: Outcomes of Professional Learning.

We examined shifts in educators' perceived knowledge, confidence, and usefulness and actual knowledge of concepts in the Comprehensive, Integrated, Three-tiered (Ci3T) model of prevention before and after participation in a practice-based professional learning series to design, implement, and evaluate a Ci3T model for their school. Participants completed the Knowledge, Confidence, and Use (KCU) survey prior to and at the conclusion of the year-long, six-part Ci3T Professional Learning Series. Results indicated participants demonstrated statistically significant increases in perceived and actual knowledge, perceived confidence, and perceived usefulness of concepts measured, with effect sizes suggesting large effects.

Extradural decompression versus duraplasty in Chiari malformation type I with syrinx: outcomes on scoliosis from the Park-Reeves Syringomyelia Research Consortium.

Objective: Scoliosis is common in patients with Chiari malformation type I (CM-I)-associated syringomyelia. While it is known that treatment with posterior fossa decompression (PFD) may reduce the progression of scoliosis, it is unknown if decompression with duraplasty is superior to extradural decompression.

Methods: A large multicenter retrospective and prospective registry of 1257 pediatric patients with CM-I (tonsils ≥ 5 mm below the foramen magnum) and syrinx (≥ 3 mm in axial width) was reviewed for patients with scoliosis who underwent PFD with or without duraplasty.

Advancing research for HIV prevention among African, Caribbean and Black men: Protocol for a multisite cross-sectional study in Ontario (weSpeak study).

In Ontario, African, Caribbean, and Black (ACB) men account for almost 60% of the estimated number of HIV-positive people (through heterosexual contact), although they constitute less than 5% of the province's population. However, current HIV research, programming and policy in Ontario are not aligned with heterosexual ACB men's healthcare needs and interests, and fail to engage them in community responses to HIV. weSpeak is a multisite (Ottawa, Toronto, London, and Windsor) project that is aims to: 1.

Imaging characteristics associated with surgery in Chiari malformation type I.

Objective: In Chiari malformation type I (CM-I), a variety of imaging findings have been purported to be important; however, results have been inconclusive, inconsistent, or not replicated in independent studies. The purpose of this study was to report imaging characteristics for a large cohort of patients with CM-I and identify the imaging findings associated with surgical decompression.

Methods: Patients were identified using ICD-9 codes for CM-I for the period from 1996 to 2017.

Cerebrospinal fluid NCAM-1 concentration is associated with neurodevelopmental outcome in post-hemorrhagic hydrocephalus of prematurity.

Objective: Efforts directed at mitigating neurological disability in preterm infants with intraventricular hemorrhage (IVH) and post hemorrhagic hydrocephalus (PHH) are limited by a dearth of quantifiable metrics capable of predicting long-term outcome. The objective of this study was to examine the relationships between candidate cerebrospinal fluid (CSF) biomarkers of PHH and neurodevelopmental outcomes in infants undergoing neurosurgical treatment for PHH.

Study Design: Preterm infants with PHH were enrolled across the Hydrocephalus Clinical Research Network.

Occipital-Cervical Fusion and Ventral Decompression in the Surgical Management of Chiari-1 Malformation and Syringomyelia: Analysis of Data From the Park-Reeves Syringomyelia Research Consortium.

Background: Occipital-cervical fusion (OCF) and ventral decompression (VD) may be used in the treatment of pediatric Chiari-1 malformation (CM-1) with syringomyelia (SM) as adjuncts to posterior fossa decompression (PFD) for complex craniovertebral junction pathology.

Objective: To examine factors influencing the use of OCF and OCF/VD in a multicenter cohort of pediatric CM-1 and SM subjects treated with PFD.

Methods: The Park-Reeves Syringomyelia Research Consortium registry was used to examine 637 subjects with cerebellar tonsillar ectopia ≥ 5 mm, syrinx diameter ≥ 3 mm, and at least 1 yr of follow-up after their index PFD.

Smoke-free environments: current status and remaining challenges in Australia.

Objectives: Smoke-free environments have been one of the great success stories in tobacco control in Australia. In this paper, we describe the current situation with respect to smoke-free environments in Australia, identify opportunities for extending and/or strengthening smoke-free environments, and discuss the challenges alternative nicotine delivery devices such as e-cigarettes pose to the traditional notion of 'smoke-free'. Type of program: Smoke-free environments are an essential element in a comprehensive approach to tobacco control.

The growth of pediatric neurosurgery in southern Vietnam and the first separation of pygopagus twins: case report.

Conjoined twins are a rare congenital abnormality with an estimated incidence of 1:50,000 pregnancies and 1:200,000 live births. Pygopagus twins are characterized by sacrococcygeal fusion that is commonly associated with perineal and spinal abnormalities. Management of this complex disease requires a well-developed surgical system with multidisciplinary capacity and expertise.

Outcomes in children undergoing posterior fossa decompression and duraplasty with and without tonsillar reduction for Chiari malformation type I and syringomyelia: a pilot prospective multicenter cohort study.

Objective: Despite significant advances in diagnostic and surgical techniques, the surgical management of Chiari malformation type I (CM-I) with associated syringomyelia remains controversial, and the type of surgery performed is surgeon dependent. This study's goal was to determine the feasibility of a prospective, multicenter, cohort study for CM-I/syringomyelia patients and to provide pilot data that compare posterior fossa decompression and duraplasty (PFDD) with and without tonsillar reduction.

Methods: Participating centers prospectively enrolled children suffering from both CM-I and syringomyelia who were scheduled to undergo surgical decompression.

The Chiari I malformation.

As with many pathologies, the course of our understanding of the Chiari I malformation (CIM) has developed extensively over time. The early descriptions of the Chiari malformations by Hans Chiari in 1891 opened the door for future classification and research on this topic. However, even over a long timeframe, our understanding of the pathophysiology and, more importantly, treatment, remained in its infancy.

Radiological and clinical predictors of scoliosis in patients with Chiari malformation type I and spinal cord syrinx from the Park-Reeves Syringomyelia Research Consortium.

Objective: Scoliosis is frequently a presenting sign of Chiari malformation type I (CM-I) with syrinx. The authors' goal was to define scoliosis in this population and describe how radiological characteristics of CM-I and syrinx relate to the presence and severity of scoliosis.

Methods: A large multicenter retrospective and prospective registry of pediatric patients with CM-I (tonsils ≥ 5 mm below the foramen magnum) and syrinx (≥ 3 mm in axial width) was reviewed for clinical and radiological characteristics of CM-I, syrinx, and scoliosis (coronal curve ≥ 10°).

Pfeiffer type 2 syndrome: review with updates on its genetics and molecular biology.

Introduction: Pfeiffer syndrome is a rare autosomal dominant inherited disorder associated with craniosynostosis, midfacial hypoplasia, and broad thumbs and toes. The syndrome has been divided into three clinical subtypes based on clinical findings.

Methods: This review will specifically examine the most severe type, Pfeiffer syndrome type 2, focusing on its genetics and molecular biology.

Reinfection rates following adherence to Infectious Diseases Society of America guideline recommendations in first cerebrospinal fluid shunt infection treatment.

Objective: CSF shunt infection treatment requires both surgical and antibiotic decisions. Using the Hydrocephalus Clinical Research Network (HCRN) Registry and 2004 Infectious Diseases Society of America (IDSA) guidelines that were not proactively distributed to HCRN providers, the authors previously found high adherence to surgical recommendations but poor adherence to intravenous (IV) antibiotic duration recommendations. In general, IV antibiotic duration was longer than recommended.

Patients with "benign" Chiari I malformations require surgical decompression at a low rate.

Objective: There are sparse published data on the natural history of "benign" Chiari I malformation (CM-I)-i.e., Chiari with minimal or no symptoms at presentation and no imaging evidence of syrinx, hydrocephalus, or spinal cord signal abnormality.

Comprehensive Review of Spinal Neurenteric Cysts with a Focus on Histopathological Findings.

Among the occult spinal dysraphisms, neurenteric cysts (NECs) are rare and are thought to arise due to a failure of the separation of the primitive endoderm and ectoderm. Patients experience various neurological symptoms depending on the location of the lesion. As the epithelial morphology of NECs share similarities with other intracranial and intraspinal cystic growths, the definitive diagnosis of NEC can be made after a histochemical analysis with endodermal markers.

A comprehensive review of Mongolian spots with an update on atypical presentations.

Purpose: Mongolian spots (MS) are grayish-blue macules that typically present in the lumbosacral and gluteal regions of newborns. They are mostly benign and tend to resolve with age. This review brings to light recent findings and disorders associated MS.
