INTRODUCTION: The resolution rate of prenatal urinary tract dilation (UTD) has been documented in several retrospective studies. The present study analyzed prospective observational registry data, with the aim of determining time to resolution among patients prenatally identified with mild postnatal UTD. MATERIALS AND METHODS: A total of 248 subjects, from four centers, were prospectively enrolled from 2008 to 2015. Exclusion criteria included other anomalies (n = 69), fewer than two ultrasounds, and/or <3 months follow-up (n = 26)...

INTRODUCTION: The urinary tract dilation (UTD) classification system was introduced to standardize terminology in the reporting of hydronephrosis (HN), and bridge a gap between pre- and postnatal classification such as the Society for Fetal Urology (SFU) grading system. Herein we compare the intra/inter-rater reliability of both grading systems. MATERIALS AND METHODS: SFU (I-IV) and UTD (I-III) grades were independently assigned by 13 raters (9 pediatric urology staff, 2 nephrologists, 2 radiologists), twice, 3 weeks apart, to 50 sagittal postnatal ultrasonographic views of hydronephrotic kidneys...

OBJECTIVES: We compared effectiveness and cost-effectiveness of: 1) centralized reminder/recall (C-R/R) using the Colorado Immunization Information System (CIIS) versus practice-based reminder/recall (PB-R/R) approaches to increase immunization rates; 2) different levels of C-R/R intensity; and 3) C-R/R with versus without the name of the child's provider. METHODS: We conducted 3 sequential cluster-randomized trials involving children 19-25 months in 15 Colorado counties in 3/2013 (trial 1), 10/2013 (trial 2), and 5/2014 (trial 3)...

BACKGROUND: The urinary tract dilation (UTD) classification system was proposed in 2014. OBJECTIVE: To evaluate the correspondence and reliability of two US grading systems for postnatal urinary tract dilatation in infants: the Society for Fetal Urology (SFU) and the UTD systems. MATERIALS AND METHODS: We assessed 180 kidneys in infants younger than 1 year. Four radiologists assessed the kidneys twice using both the SFU system (grades 0 to 4) and the UTD system (grades normal, P1, P2, P3)...

OBJECTIVE: To explore the potential value of an objective assessment, renal parenchyma-to-hydronephrosis area ratio (PHAR), as an early predictor of surgery. MATERIALS AND METHODS: Initial sagittal renal ultrasound images of patients prospectively entered into a prenatal hydronephrosis (PHN) database from January 2008-2016 with baseline SFU grades III and IV PHN, without vesicoureteral reflux, were evaluated using NIH-sponsored image-processing software. PHAR, APd, SFU grade and urinary tract dilation (UTD) risk categories were contrasted with nuclear scan data (differential renal function [DRF] and drainage time [t ½]), and analyzed for predictive value in determining the decision to proceed with surgery by drawing receiver operator characteristic curves...

PURPOSE: There are limited comparative data on the predictive value of the 2 most commonly used classification systems, that is SFU (Society for Fetal Urology) hydronephrosis grades and urinary tract dilatation risk groups, in regard to the future risk of surgical intervention and the development of febrile urinary tract infection. We explored this topic in infants with isolated hydronephrosis. MATERIALS AND METHODS: After screening 938 patients with prenatal hydronephrosis from 2009 to 2016 we selected 322 patients with ureteropelvic junction obstruction-like hydronephrosis for study...

INTRODUCTION: Antenatal hydronephrosis (ANH) is frequently detected on screening obstetric ultrasonography. Common ANH grading systems include the anterior-posterior diameter (APD) and the Society for Fetal Urology (SFU) grading system. Recent developments in the management of ANH include the use of fetal magnetic resonance imaging (MRI), and a new grading system - Urinary Tract Dilation (UTD). This study reviewed patients who underwent fetal MRI and ultrasound, and compared the grading systems across these imaging modalities...

INTRODUCTION: Urinary stasis in the setting of obstruction provides an opportunistic environment for bacterial multiplication and is a well-established risk factor for UTI. Vesicoureteral reflux (VUR) with delayed upper tract drainage (UTD) on VCUG has been reported to correlate with increased UTI risk. We sought to determine whether delayed UTD can be reliably classified, and whether it correlates with UTI incidence, VCUG, or endoscopic findings. METHODS: Children undergoing endoscopic surgery for primary VUR (2009-2012) were identified...

This study examined whether additional information on parents' employment and household characteristics would help explain the differences in children's up-to-date (UTD) vaccination status using the 2008 National Immunization Survey and its associated Socioeconomic Status Module. After controlling for basic sociodemographic factors in multivariable analyses, parent's work schedules and ease of taking time off from work were not associated with UTD vaccination status among 19- to 35-month-old children. We also conducted a stratified analysis to test the heterogeneous effects of the factors among children at 3 age-restricted maternal education levels and found the benefit of paid sick leave had a significant association only among families where the mother had a college degree...

INTRODUCTION: Renograms are frequently obtained post-pyeloplasty in patients with residual hydronephrosis to confirm adequate drainage. Recent evidence suggests that percent improvement in antero-posterior diameter (PI-APD) ≥38 is predictive of success. We sought to further explore PI-APD ranges that would allow identification of patients who would benefit from ultrasound (US) monitoring alone vs. post-operative renal scan, and those more likely to develop recurrent ureteropelvic junction obstruction (rUPJO)...

This study seeks to better understand the impact of practice-level factors on up-to-date (UTD) rates in children. We compared practice-level vaccination rates for 54 practices to survey data regarding office practices for staffing, vaccine delivery, reminder-recall, and quality improvement. Vaccination rates at 24 and 35 months were analyzed using t tests, analysis of variance, and linear regression. Private practices and those using standing orders had higher UTD rates at 24 months (P = .01; P = .03), but not at 35 months...

National data on vaccine up-to-date (UTD) suggest that insufficient numbers of adolescents receive needed vaccines. This study analyzed public use data of the National Immunization Survey-Teen (NIS-Teen) from 2010 through 2013 for South Carolina (SC) adolescents and compared immunization rates to those of United States (US) adolescents. We also examined trends for each vaccine recommended for adolescents for both SC and US adolescents. UTD rates in SC adolescents for the quadrivalent meningococcal conjugate vaccine (MCV4) and the tetanus- diphtheria, acellular pertussis (Tdap) vaccine lag those of US adolescents, despite demonstrating a trend of improvement in SC adolescents from 45% to 69% for MCV and from 48% to 72% for Tdap...

BACKGROUND: Nationally, immunization coverage for the DTaP/3HPV/1MMR/3HepB/3Hib/1VZV antigen series in children ages 19-35 months are near or above the Healthy People 2020 target (80%). However, children in lower socioeconomic families experience lower coverage rates. OBJECTIVE: Using a community-based participatory research (CBPR) approach, Community Health Improvement for Milwaukee Children (CHIMC) intervened to reduce disparities in childhood immunizations. METHODS: The CHIMC adopted a self-assessment to examine the effectiveness of adhering to CBPR principles...

Yoshihiro Sugi, Ajayan Vinu
Steric interaction of reagents with nanospace of zeolites was studied in alkylation: isopropylation, sec-butylation, and tert-butylation of naphthalene (NP) over several large-pore zeolites to elucidate the mechanism of shape-selective catalysis. Selectivities for β,β- and 2,6-dialkylnaphthalene (DAN) were influenced by the type of zeolite and bulkiness of alkylating agent. Shape-selective formation of β,β- and 2,6-diisopropylnaphthalene (DIPN) occurred only over H-mordenite (MOR) in the isopropylation of NP...

Diffraction phenomena studied in electromagnetism, acoustics, and elastodynamics are often modeled using integrals, such as the well-known Sommerfeld integral. The far field asymptotic evaluation of such integrals obtained using the method of steepest descent leads to the classical Geometrical Theory of Diffraction (GTD). It is well known that the method of steepest descent is inapplicable when the integrand's stationary phase point coalesces with its pole, explaining why GTD fails in zones where edge diffracted waves interfere with incident or reflected waves...

PURPOSE: We assessed the reliability and validity of the Urinary Tract Dilation classification system as a new grading system for postnatal hydronephrosis. MATERIALS AND METHODS: We retrospectively reviewed charts of patients who presented with hydronephrosis from 2008 to 2013. We included patients diagnosed prenatally and those with hydronephrosis discovered incidentally during the first year of life. We excluded cases involving urinary tract infection, neurogenic bladder and chromosomal anomalies, those associated with extraurinary congenital malformations and those with followup of less than 24 months without resolution...

Ultrasonic telemetry imaging systems are used to monitor such immersed structures as main vessels of nuclear reactors. The interaction between acoustic beams and targets involves scattering phenomena, mainly specular reflection and tip diffraction. In order to assist in the design of imaging systems, a simulation tool is required for the accurate modeling of such phenomena. Relevant high-frequency scattering models have been developed in electromagnetic applications, in particular, the geometrical optics (GO), Geometrical Theory of Diffraction (GTD) and its uniform corrections (UAT and UTD), Kirchhoff approximation (KA) and Physical Theory of Diffraction (PTD)...
