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...

INTRODUCTION: There is limited comparative data on the predictive value of the two most commonly employed classification systems (SFU hydronephrosis[HN] grades and urinary tract dilation[UTD] risk groups) in regards to future risk for surgical intervention and the development of fUTI. Herein we explore this topic in infants with isolated HN. METHODS: After screening 938 patients with prenatal HN (2009-2016), we selected patients with UPJO-like HN(n=322). HN grades were prospectively collected at baseline, surgery and last follow-up...

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)...

OBJECTIVE: New emphasis on and requirements for demonstrating health care quality have increased the need for evidence-based methods to disseminate practice guidelines. With regard to impact on pediatric immunization coverage, we aimed to compare a financial incentive program (pay-for-performance [P4P]) and a virtual quality improvement technical support (QITS) learning collaborative. METHODS: This single-blinded (to outcomes assessor), cluster-randomized trial was conducted among unaffiliated pediatric practices across the United States from June 2013 to June 2014...

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...

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)...

BACKGROUND: Vaccination uptake at the individual level can be assessed in a variety of ways, including traditional measures of being up-to-date (UTD), measures of UTD that consider dose timing, like age-appropriate vaccination, and risk reduction from individual doses. This analysis compared methods of operationalizing vaccination uptake and corresponding risk of pertussis infection. METHODS: City-wide case-control study of children in Philadelphia aged 3 months through 6 years, between 2001 and 2013...

PURPOSE: The aim of this study was to assess the effectiveness and cost efficiency of three reminder/recall methods for improving adolescent vaccination rates using the San Diego Immunization Registry. METHODS: Parents of 5,050 adolescents whose records indicated they lacked one or more adolescent vaccines were identified from the San Diego Immunization Registry and contacted by telephone. Based on their preference, consenting participants were enrolled to receive either postal mail (n = 282), e-mail (n = 963), or text (n = 552) reminders for vaccination...

IMPORTANCE: Reminder/recall notifications used by primary care practices increase the rates of childhood immunizations, but fewer than 20% of primary care practitioners nationally deliver such reminders. A reminder/recall notification conducted centrally by health departments in collaboration with primary care practices may reduce practice burden, reach children without a primary care practitioner, and decrease the cost of reminders/recalls. OBJECTIVE: To assess the effectiveness and cost-effectiveness of collaborative centralized (CC) vs practice-based (PB) reminder/recall approaches using the Colorado Immunization Information System (CIIS)...

Nitrate lost from agricultural soils is an economic cost to producers, an environmental concern when it enters rivers and lakes, and a health risk when it enters wells and aquifers used for drinking water. Planting a winter wheat cover crop (CC) and/or use of controlled tile drainage-subirrigation (CDS) may reduce losses of nitrate (NO) relative to no cover crop (NCC) and/or traditional unrestricted tile drainage (UTD). A 6-yr (1999-2005) corn-soybean study was conducted to determine the effectiveness of CC+CDS, CC+UTD, NCC+CDS, and NCC+UTD treatments for reducing NO loss...
