The Impact Of Household Investments On Early Child Neurodevelopment And On Racial And Socioeconomic Developmental Gaps: Evidence From South America, Ann Mccarthy May 2012

The Impact Of Household Investments On Early Child Neurodevelopment And On Racial And Socioeconomic Developmental Gaps: Evidence From South America, Ann Mccarthy

Ann Marie McCarthy

This paper assesses the effects of household investments through child educating activities on child neurodevelopment between the ages of 3 and 24 months, and evaluates whether investments explain racial and socioeconomic developmental gaps in South America. Quantile regression is used to evaluate the heterogeneity in investment effects by unobserved developmental endowments. The study finds large positive investment effects on early child neurodevelopment, with generally larger effects among children with low developmental endowments (children at the left margin of the development distribution). Investments explain part of the observed racial gaps and the whole socioeconomic developmental gap. Investments may compensate for low …

OBJECTIVE: To evaluate the utility of the Bayley Infant Neurodevelopmental Screener (BINS), standardized in the US, for South American infants, 3-24 months of age. METHODS: Thirty-five physicians administered the BINS to 2471 South American infants recruited during routine well-child visits, 578 (23%) from Brazil and 1893 (77%) from six other South American countries. The BINS was translated into Spanish and Portuguese and participating physicians were trained to administer the BINS. Physician inter-rater agreement with training tapes was 84.4%; test-retest reliability for age item sets ranged from 0.80 to 0.93 (Pearson's r). Infants were classified into being at low, moderate, or …


Clinical Features And Outcomes Of 98 Children And Adults With Dense Deposit Disease, Der-Fa Lu, M. Moon, L. Lanning, Anne Mccarthy, R. Smith May 2012

Clinical Features And Outcomes Of 98 Children And Adults With Dense Deposit Disease, Der-Fa Lu, M. Moon, L. Lanning, Anne Mccarthy, R. Smith

Ann Marie McCarthy

BACKGROUND: Dense deposit disease (DDD) is an ultra-rare renal disease. METHODS: In the study reported here, 98 patients and their families participated in a descriptive patient-centered survey using an online research format. Reports were completed by patients (38%) or their parents (62%). Age at diagnosis ranged from 1.9 to 38.9 years (mean 14 years). RESULTS: The majority of patients presented with proteinuria and hematuria; 50% had hypertension and edema. Steroids were commonly prescribed, although their use was not evidence-based. One-half of the patients with DDD for 10 years progressed to end-stage renal disease (ESRD), with young females having the greatest …


The Impact Of Maternal Smoking During Pregnancy On Early Child Neurodevelopment, G. L. Wehby, K. Prater, Anne Marie Mccarthy, E. E. Castilla, J. C. Murray May 2012

The Impact Of Maternal Smoking During Pregnancy On Early Child Neurodevelopment, G. L. Wehby, K. Prater, Anne Marie Mccarthy, E. E. Castilla, J. C. Murray

Ann Marie McCarthy

Early child neurodevelopment has major impacts on future human capital and health. However, not much is known about the impacts of prenatal risk factors on child neurodevelopment. This study evaluates the effects of maternal smoking during pregnancy on child neurodevelopment between 3 and 24 months of age and interactions with socioeconomic status (SES). Data from a unique sample of children from South America are employed. Smoking has large adverse effects on neurodevelopment, with larger effects in the low SES sample. The study results highlight the importance of early interventions beginning before and during pregnancy for enhancing child development and future …


Parent Behavior And Child Distress During Urethral Catheterization, Charmaine Kleiber, Ann Marie Mccarthy Mar 2012

Parent Behavior And Child Distress During Urethral Catheterization, Charmaine Kleiber, Ann Marie Mccarthy

Ann Marie McCarthy

ISSUES AND PURPOSE: Researchers need a clear understanding of the natural behaviors parents use to help their children cope. This study describes the relationships between naturally occurring parent behaviors and child distress behaviors during urethral catheterization. DESIGN AND METHODS: In this descriptive study, researchers videotaped the behaviors of parent-child interactions during urethral catheterization. RESULTS: Parents used distraction to maintain calm behavior during the first part of the procedure and used more reassurance when the children started to become distressed. Seven of the nine children displayed calm behavior at least half the time following distraction. Parental reassurance did not decrease distress …

The Influence Of Second Intermediate Host Dispersion Pattern Upon The Transmission Of Cercariae Of Echinoparyphium Recurvatum (Digenea: Echinostomatidae), Ann Mccarthy Mar 2012

The Influence Of Second Intermediate Host Dispersion Pattern Upon The Transmission Of Cercariae Of Echinoparyphium Recurvatum (Digenea: Echinostomatidae), Ann Mccarthy

Ann Marie McCarthy

Transmission of cercariae of the echinostome digenean Echinoparyphium recurvatum was observed in experimental populations of the second intermediate host snail Lymnaea peregra. Populations of 100 snails were distributed among plastic mesh cages in an infection arena to produce different patterns of host dispersion. Cercarial transmission was investigated in host populations showing three separate patterns of host dispersion; Ideal Regular, Random and Contagious ('Clumped'). Levels of cercarial transmission in populations showing each type of dispersion pattern were found to be significantly different. The highest rate of cercarial transmission occurred in the contagiously dispersed host population, and the lowest in the randomly …


Speciation Of Echinostomes: Evidence For The Existence Of Two Sympatric Sibling Species In The Complex Echinoparyphium Recurvatum (Von Linstow 1873) (Digenea: Echinostomatidae), Ann Mccarthy Mar 2012

Speciation Of Echinostomes: Evidence For The Existence Of Two Sympatric Sibling Species In The Complex Echinoparyphium Recurvatum (Von Linstow 1873) (Digenea: Echinostomatidae), Ann Mccarthy

Ann Marie McCarthy

Evidence for the existence of 2 first intermediate host-specific sibling species of the 45 collar-spined echinostome Echinoparyphium recurvatum is presented. Experimental studies on their life-cycles were carried out under controlled laboratory conditions. The two entities were found to be morphologically indistinguishable in all major respects, yet they exhibited distinct biological characteristics. One of the sibling species utilizes the freshwater lymnaeid pulmonate snail Lymnaea peregra as first intermediate host, and the adults occur in the anterior small intestine of the wildfowl experimental definitive host Anas platyrhynchos. The other utilizes the freshwater mesogastropod prosobranch snail Valvata piscinalis as first intermediate host, and …

BACKGROUND: The contribution of birth defects, including cleft lip and palate, to neonatal and infant mortality and morbidity is substantial. As other mortality and morbidity causes including infections, hygiene, prematurity, and nutrition are eradicated in less developed countries, the burden of birth defects will increase proportionally. METHODS/DESIGN: We are using cleft lip and palate as a sentinel birth defect to evaluate its burden on neonatal and infant health and to assess the effectiveness of systematic pediatric care during the first month and first two years of life in decreasing this burden. The neonatal intervention, consisting of weekly pediatric evaluation and …
