Prenatal detection of critical cardiac outflow tract anomalies remains suboptimal despite revised obstetrical imaging guidelines.

Background: Fetal echocardiography can accurately diagnose critical congenital heart disease prenatally, but relies on referrals from abnormalities identified on routine obstetrical ultrasounds. Critical congenital heart disease that is frequently missed due to inadequate outflow tract imaging includes anomalies such as truncus arteriosus, double outlet right ventricle, transposition of the great arteries, tetralogy of Fallot, pulmonary stenosis, and aortic stenosis.

Objective: This study evaluated the prenatal detection rate of critical outflow tract anomalies in a single urban pediatric hospital before and after "AIUM Practice Guideline for the Performance of Obstetric Ultrasound Examinations," which incorporated outflow tract imaging.

The Impact of the Left Ventricle on Right Ventricular Function and Clinical Outcomes in Infants with Single-Right Ventricle Anomalies up to 14 Months of Age.

Background: Children with single-right ventricle anomalies such as hypoplastic left heart syndrome (HLHS) have left ventricles of variable size and function. The impact of the left ventricle on the performance of the right ventricle and on survival remains unclear. The aim of this study was to identify whether left ventricular (LV) size and function influence right ventricular (RV) function and clinical outcome after staged palliation for single-right ventricle anomalies.

Impact of initial shunt type on cardiac size and function in children with single right ventricle anomalies before the Fontan procedure: the single ventricle reconstruction extension trial.

Background: In children with single right ventricular (RV) anomalies, changes in RV size and function may be influenced by shunt type chosen at the time of the Norwood procedure.

Objectives: The study sought to identify shunt-related differences in echocardiographic findings at 14 months and ≤6 months pre-Fontan in survivors of the Norwood procedure.

Methods: We compared 2-dimensional and Doppler echocardiographic indices of RV size and function, neo-aortic and tricuspid valve annulus dimensions and function, and aortic size and patency at 14.

White matter lesions in children and adolescents with migraine.

Background: The etiology and clinical importance of white matter lesions in migraine remain poorly understood. To understand these issues more fully, we reviewed the brain magnetic resonance imaging scans of pediatric patients and assessed the relationships between white matter lesions, migraine type, patent foramen ovale, and right-to-left shunting.

Methods: The magnetic resonance imaging scans of a cohort of children (n = 89) and adolescents, ages 6 to 18 years, who participated in a study of migraine and patent foramen ovale were reviewed.

Risk factors for prolonged length of stay after the stage 2 procedure in the single-ventricle reconstruction trial.

Background: The single-ventricle reconstruction trial randomized patients with single right ventricle lesions to a modified Blalock-Taussig or right ventricle-to-pulmonary artery shunt at the Norwood. This analysis describes outcomes at the stage 2 procedure and factors associated with a longer hospital length of stay (LOS).

Methods: We examined the association of shunt type with stage 2 hospital outcomes.

Hispanic migrant farm workers' attitudes toward mobile phone-based telehealth for management of chronic health conditions.

Background: Mobile phone-based interventions present a means of providing high quality health care to hard-to-reach underserved populations. Migrant farm workers (MFWs) are among the most underserved populations in the United States due to a high prevalence of chronic diseases yet limited access to health care. However, it is unknown if MFWs have access to mobile phone devices used in mobile health (mHealth) interventions, or if they are willing to use such technologies.

Doppler flow patterns in the right ventricle-to-pulmonary artery shunt and neo-aorta in infants with single right ventricle anomalies: impact on outcome after initial staged palliations.

Background: A Pediatric Heart Network trial compared outcomes in infants with single right ventricle anomalies undergoing Norwood procedures randomized to modified Blalock-Taussig shunt (MBTS) or right ventricle-to-pulmonary artery shunt (RVPAS). Doppler patterns in the neo-aorta and RVPAS may characterize physiologic changes after staged palliations that affect outcomes and right ventricular (RV) function.

Methods: Neo-aortic cardiac index (CI), retrograde fraction (RF) in the descending aorta and RVPAS conduit, RVPAS/neo-aortic systolic ejection time ratio, and systolic/diastolic (S/D) ratio were measured early after Norwood, before stage II palliation, and at 14 months.

Myocardial strain and strain rate in Kawasaki disease.

Aims: We sought to determine whether velocity vector imaging (VVI)-derived left ventricular (LV) myocardial deformation indices could detect subtle myocardial abnormalities in acute Kawasaki disease (KD).

Methods And Results: The study cohort of children with KD was divided by coronary artery dilation (CAD, Z-score >2.5) and/or uncomplicated vs.

Developing a culturally appropriate preconception health promotion strategy for newly immigrated Latinos through a community-based program in South Carolina.

Maternal and Child Health (MCH) experts emphasize the importance of preconception health (PCH) in achieving healthy pregnancies and positive birth outcomes. Research demonstrates that Latinas face significant PCH disparities, yet no comprehensive PCH promotion strategy exists to reach them. As a trusted community-based organization that uses culturally competent strategies to promote MCH in the Latino community, PASOs is well-positioned to address PCH among Latinos in South Carolina.

"Her energy kind of went into a different place": a qualitative study examining supervisors' experience of promoting reflexive learning in students.

For family therapists in training, a key learning outcome is the development of reflexive abilities. This study explores the experience of three experienced training supervisors as they address this learning outcome with students. Transcripts of semi-structured interviews were analyzed using interpretative phenomenological analysis.

Clinical outcomes and resource use for infants with hypoplastic left heart syndrome during bidirectional Glenn: summary from the Joint Council for Congenital Heart Disease National Pediatric Cardiology Quality Improvement Collaborative registry.

The National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) registry captures information on interstage management of infants with hypoplastic left heart syndrome (HLHS). The purpose of this study was to identify interstage risk factors for increased resource use and adverse outcomes during bidirectional Glenn (BDG) hospitalization. All infants in the NPC-QIC registry (31 United States hospitals) undergoing BDG surgery were included (December 2009 to August 2010).

Prenatally diagnosed coarctation: a more sinister disease?

Prenatal diagnosis of coarctation may improve survival, but little is known regarding its association with severity of left heart hypoplasia and surgical outcome. This study compared echocardiographic measurements of left heart structures, surgical strategies, and postoperative outcomes between neonates with a prenatal diagnosis of coarctation and those with a postnatal diagnosis. All the neonates who underwent coarctation repair during 2006-2010 were reviewed.

Patent foramen ovale in children with migraine headaches.

Objective: To determine the prevalence of patent foramen ovale (PFO) in children with migraine.

Study Design: Children aged 6.0 to 18.

Does abciximab promote coronary artery remodeling in patients with Kawasaki disease?

Standard therapy, consisting of intravenous immunoglobulin and aspirin, reduces, but does not eliminate, coronary artery aneurysms (CAAs) in patients with Kawasaki disease. Large CAAs can persist or undergo varying degrees of regression. The treatment of large CAAs using abciximab has been associated with short-term regression; however, longer term data are unavailable.

Enhancing nuclear emergency preparedness: Vermont's distribution program for potassium iodide.

On January 31, 2002, Vermont's health commissioner requested potassium iodide (KI) for individuals in the 10-mile Emergency Planning Zone of the nuclear power facility. Vermont's KI distribution program emphasized public information about the role, risks, and benefits of KI. Predistribution ensured that individuals could receive KI in a 0- to 4-hour time period, to provide maximum protection.

Attributing inpatient medicare costs to diabetes among the Texas elderly.

Objective: This study compares alternative methods for attributing hospital utilization and costs to diabetes. Findings from five "numerator" methods, found in the literature and based on presence of certain diagnoses or combinations of diagnoses in the billing records, were compared to benchmark findings derived from attributable risk calculations.

Research Design And Methods: Estimates of non-HMO, short-term, nonspecialized hospital stays, hospital days, and costs attributable to diabetes in Texas were derived from the 1995 Medicare inpatient database (MEDPAR) for persons aged at least 65 years at the end of 1994.

Effect of hydroxypropyl-beta-cyclodextrin and pH on the solubility of levemopamil HCl.

Levemopamil was solubilized by varying the concentration of hydroxypropyl-beta-cyclodextrin (HPbetaCD) and by the alteration of pH. The drug molecule has two sites for possible complexation with HPbetaCD, creating the possibility of either 1:1 or 1:2 complexation. The solubility as a function of HPbetaCD concentration of the charged and uncharged forms of the drug follows the A(L) and Ap complexation models, respectively.

Costs of diabetes in Texas, 1992.

Objective: To estimate direct and indirect costs of diabetes in Texas in 1992.

Research Design And Methods: For most direct medical costs, we relied on third party and provider billing databases, including Medicare, Medicaid, VA facilities, public hospitals, and others. The researchers identified people with diabetes in the respective databases, located all records of their care, and sorted records as clearly, probably, or probably not attributable to diabetes on the basis of principal diagnoses.

Self-association of dexverapamil in aqueous solution.

The pKa and intrinsic solubility of monomeric dexverapamil were determined from its pH-solubility profile to be 8.90 and 6.6 x 10(-5) M, respectively.

A cost-effectiveness evaluation of primary health care projects for the poor.

A cost-effectiveness analysis was conducted to determine the relative efficacy of nine primary health care projects serving low income persons in urban and rural areas of Texas. The projects were created as part of a government program to provide services in medically underserved areas of the state by contracting with local public and private providers. While they vary widely in terms of sponsoring organizations, service strategy, and scope of services, the projects share a similar goal of providing an array of basic medical and preventive care services to the poor.
