RESUMEN
OBJECTIVE: To assess limited English proficiency (LEP) asthma caregiver quality of life (QoL), skills retention and healthcare utilization after an asthma education fair (AEF). METHODS: A language concordant AEF was conducted at a Latino community center. LEP caregivers of children 1-12 years old and an established asthma diagnosis participated in three skill stations: (a) medication recognition and administration, (b) peak flow use (if child ≥ 5 years) and (c) action plan dissemination. Spacers, peak flow meters and individualized action plans were distributed. A validated, pediatric asthma caregiver quality of life questionnaire (PACQLQ-Spanish version) was administered. Baseline data was compared to follow-up interview data at three and six months after the AEF. Mean PACQLQ scores were analyzed with Wilcoxon signed-rank test and nominal paired data with McNemar's test. RESULTS: We analyzed data from 18 caregivers able to speak English well (22%), not well (28%) or not at all (50%). After three months, improved caregiver QoL was experienced (51 vs. 72, p<0.01). No differences were observed in medication recognition, spacer and peak flow use or peak flow interpretation. After six months, mean school days missed due to asthma decreased (4.1 vs. 0.4, p<0.01). Mean clinic visits, emergency department visits and hospitalizations remained unchanged. CONCLUSIONS: Implementation of a community-based AEF with action plan administration can be beneficial for LEP caregivers and their children. QoL improvements to emotional wellbeing and activity limitations were observed, and lower rates of school absenteeism were reported. Caregiver ability to accurately identify medications was not enhanced.

AIM: To compare the impact of low-grade haemorrhage on neurocognitive function in 16-year-old adolescents born preterm, by grade of intraventricular haemorrhage, and term controls. METHODS: We evaluated 338 preterm adolescents (birth weight 600-1250 g) for intelligence, executive function and memory tasks. Eleven had grade 3-4 haemorrhage, 44 had grade 2, 31 had grade 1, and 251 had no haemorrhage. Group comparisons were made with 102 term age-matched controls, and regression models used to identify the risk that low-grade haemorrhage posed for cognitive, executive function and memory deficits. RESULTS: Preterm adolescents with grade 2 haemorrhage had higher deficit rates of verbal intelligence, receptive vocabulary, phonemic fluency, cognitive flexibility and phonological fluency than preterm adolescents with grade 1 or no haemorrhage, compared with term controls. After excluding preterm adolescents with both grade 2 haemorrhage and cystic periventricular leukomalacia, those with isolated grade 2 haemorrhage remained at greater risk of cognitive and executive function deficits than term controls and of cognitive deficits than preterm adolescents with no haemorrhage. CONCLUSION: Our findings suggest that preterm adolescents born in the early 1990s with isolated grade 2 haemorrhage are at increased risk of learning challenges, including cognitive and executive function deficits.

Preterm (PT) subjects are at risk for developmental delay, and task-based studies suggest that developmental disorders may be due to alterations in neural connectivity. Since emerging data imply the importance of right cerebellar function for language acquisition in typical development, we hypothesized that PT subjects would have alternate areas of cerebellar connectivity, and that these areas would be responsible for differences in cognitive outcomes between PT subjects and term controls at age 20 years. Nineteen PT and 19 term control young adults were prospectively studied using resting-state functional MRI (fMRI) to create voxel-based contrast maps reflecting the functional connectivity of each tissue element in the grey matter through analysis of the intrinsic connectivity contrast degree (ICC-d). Left cerebellar ICC-d differences between subjects identified a region of interest that was used for subsequent seed-based connectivity analyses. Subjects underwent standardized language testing, and correlations with cognitive outcomes were assessed. There were no differences in gender, hand preference, maternal education, age at study, or Peabody Picture Vocabulary Test (PPVT) scores. Functional connectivity (FcMRI) demonstrated increased tissue connectivity in the biventer, simple and quadrangular lobules of the L cerebellum (p<0.05) in PTs compared to term controls; seed-based analyses from these regions demonstrated alterations in connectivity from L cerebellum to both R and L inferior frontal gyri (IFG) in PTs compared to term controls. For PTs but not term controls, there were significant positive correlations between these connections and PPVT scores (R IFG: r=0.555, p=0.01; L IFG: r=0.454, p=0.05), as well as Verbal Comprehension Index (VCI) scores (R IFG: r=0.472, p=0.04). These data suggest the presence of a left cerebellar language circuit in PT subjects at young adulthood. These findings may represent either a delay in maturation or the engagement of alternative neural pathways for language in the developing PT brain.

This study tested the hypothesis that preterm early adolescents' short-term memory is compromised when presented with increasingly complex verbal information and that associated neuroanatomical volumes would differ between preterm and term groups. Forty-nine preterm and 20 term subjects were evaluated at age 12 years with neuropsychological measures and magnetic resonance imaging (MRI). There were no differences between groups in simple short-term and working memory. Preterm subjects performed lower on learning and short-term memory tests that included increased verbal complexity. They had reduced right parietal, left temporal, and right temporal white matter volumes and greater bilateral frontal gray and right frontal white matter volumes. There was a positive association between complex working memory and the left hippocampus and frontal white matter in term subjects. While not correlated, memory scores and volumes of cortical regions known to subserve language and memory were reduced in preterm subjects. This study provides evidence of possible mechanisms for learning problems in former preterm infants.

Prematurely born children are at increased risk for cognitive deficits, but the neurobiological basis of these findings remains poorly understood. Because variations in neural circuitry may influence performance on cognitive tasks, recent investigations have explored the impact of preterm birth on connectivity in the developing brain. Diffusion tensor imaging studies demonstrate widespread alterations in fractional anisotropy, a measure of axonal integrity and microstructural connectivity, throughout the developing preterm brain. Functional connectivity studies report that preterm neonates, children and adolescents exhibit alterations in both resting state and task-based connectivity when compared with term control subjects. Taken together, these data suggest that neurodevelopmental impairment following preterm birth may represent a disease of neural connectivity.

OBJECTIVE: Given the propensity for heart disease in obese patients, the authors investigated the effects of pneumoperitoneum on cardiac performance. DESIGN: A pilot observational intraoperative study. SETTING: A single-center university hospital. PARTICIPANTS: Patients undergoing laparoscopic gastric bypass surgery. INTERVENTIONS: Abdominal insufflation. MEASUREMENTS AND RESULTS: Hemodynamic, respiratory, and echocardiographic data were collected at 4 epochs: (1) baseline after the induction of anesthesia, (2) after abdominal insufflation in supine position, (3) after abdominal insufflation in the reverse Trendelenburg (RT) position, and (4) after desufflation in RT position. At epoch 1, 3 of 13 patients manifested systolic dysfunction (SD), 5 of 13 patients exhibited diastolic dysfunction (DD) according to transmitral flow (TMF) Doppler criteria, and 4 of 8 patients according to Doppler tissue imaging (DTI) criteria. With pneumoperitoneum, the total systemic resistance increased to values of 142% from baseline (p < 0.05). Compared with baseline, stroke volume decreased by 25%, cardiac output by 35%, and fractional area change by 13% (p < 0.05). Mean arterial blood pressure and heart rate remained stable. Additionally, new-onset DD manifested in 1 of 8 patients according to TMF criteria and in 3 of 4 patients according to DTI criteria. Desufflation of the abdomen reverted the diastolic function to baseline in all but 1 patient. CONCLUSION: The study data revealed that surgical pneumoperitoneum used in patients with clinically severe obesity resulted in the deterioration of cardiac performance including the development of new-onset DD. These patients, despite their relative young age and without a history of heart failure or coronary artery disease, displayed a cardiovascular profile during laparoscopic surgery similar to that seen in patients with significant heart disease.

Very low birth weight preterm (PT) children are at high risk for brain injury. Employing diffusion tensor imaging (DTI), we tested the hypothesis that PT adolescents would demonstrate microstructural white matter disorganization relative to term controls at 16 years of age. Forty-four PT subjects (600-1250 g birth weight) without neonatal brain injury and 41 term controls were evaluated at age 16 years with DTI, the Wechsler Intelligence Scale for Children-III (WISC), the Peabody Picture Vocabulary Test-Revised (PPVT), and the Comprehensive Test of Phonological Processing (CTOPP). PT subjects scored lower than term subjects on WISC full scale (p=0.003), verbal (p=0.043), and performance IQ tests (p=0.001), as well as CTOPP phonological awareness (p=0.004), but scored comparably to term subjects on PPVT and CTOPP Rapid Naming tests. PT subjects had lower fractional anisotropy (FA) values in multiple regions including bilateral uncinate fasciculi (left: p=0.01; right: p=0.004), bilateral external capsules (left: p<0.001; right: p<0.001), the splenium of the corpus callosum (p=0.008), and white matter serving the inferior frontal gyrus bilaterally (left: p<0.001; right: p=0.011). FA values in both the left and right uncinate fasciculi correlated with PPVT scores (a semantic language task) in the PT subjects (left: r=0.314, p=0.038; right: r=0.336, p=0.026). FA values in the left and right arcuate fasciculi correlated with CTOPP Rapid Naming scores (a phonologic task) in the PT subjects (left: r=0.424, p=0.004; right: r=0.301, p=0.047). These data support for the first time that dual pathways underlying language function are present in PT adolescents. The striking bilateral dorsal correlations for the PT group suggest that prematurely born subjects rely more heavily on the right hemisphere than typically developing adults for performance of phonological language tasks. These findings may represent either a delay in maturation or the engagement of alternative neural pathways for language in the developing PT brain.

OBJECTIVE: To assess the blood pressure of former preterm and term matched adolescent controls and to identify risk factors associated with blood pressure at 16 years. DESIGN: Observational cohort study. Secondary analysis of a randomized clinical trial. SETTING: Three academic centres participating in the Multicenter Indomethacin IVH Prevention Trial. PARTICIPANTS: A total of 296 children born in 1989-1992 with birth weights 600 to <1250 g who participated in the Multicenter Indomethacin IVH Prevention Trial and 95 term controls were evaluated at 16 years. MAIN OUTCOME MEASURES: Blood pressure and predictors of blood pressure. RESULTS: The adjusted mean difference in blood pressure for preterm adolescents was 5.1 mm Hg; p=0.002 for systolic and 2.1 mm Hg; p=0.027 for diastolic blood pressure. Among preterms, the primary predictors of increased systolic blood pressure were weight gain velocity between birth and 36 months (b=8.54, p<0.001), pre-eclampsia (b=5.67, p=0.020), non-white race (b=3.77, p=0.04) and male gender (b=5.09). Predictors of diastolic blood pressure were weight gain velocity between birth and 36 months (b=4.69, p=0.001), brain injury (b=6.51, p=0.002) and male gender (b=-2.4, p=0.02). CONCLUSIONS: Early programming secondary to increased early weight gain velocity, intrauterine stress and neonatal brain injury may all contribute to risk of increased blood pressure among former preterm adolescents.

Prematurely born children are at increased risk for language deficits at school age and beyond, but the neurobiological basis of these findings remains poorly understood. Thirty-one PT adolescents (600-1250g birth weight) and 36 T controls were evaluated using an fMRI passive language task and neurodevelopmental assessments including: the Wechsler Intelligence Scale for Children-III (WISC-III), the Peabody Picture Vocabulary Test-Revised (PPVT-R), the Comprehensive Test of Phonological Processing (CTOPP) and the Test of Word Reading Efficiency (TOWRE) at 16years of age. Neural activity was assessed for language processing and the data were evaluated for connectivity and correlations to cognitive outcomes. PT subjects scored significantly lower on all components of the WISC-III (p<0.05) compared to term subjects, but there was no significant difference in PPVT-R scores between the groups. Functional connectivity (fcMRI) between Wernicke's area (left BA 22) and the right supramarginal gyrus (BA 40) was increased in preterm subjects relative to term controls (p=0.03), and the strength of this connection was inversely related to performance on both the PPVT-R (R(2)=0.553, p=0.002), and the verbal comprehension index (R(2)=0.439, p=0.019). Preterm adolescents engage a dorsal right hemisphere region for language at age 16years. Those with the greatest cognitive deficits demonstrate increasing reliance on this alternate pathway.

OBJECTIVES: The goal was to examine whether indomethacin use, gender, neonatal, and sociodemographic factors predict patterns of receptive language development from 3 to 12 years of age in preterm children. METHODS: A total of 355 children born in 1989-1992 with birth weights of 600 to 1250 g were evaluated at 3, 4.5, 6, 8, and 12 years with the Peabody Picture Vocabulary Test-Revised. Hierarchical growth modeling was used to explore differences in language trajectories. RESULTS: From 3 to 12 years, preterm children displayed catch-up gains on the Peabody Picture Vocabulary Test-Revised. Preterm children started with an average standardized score of 84.1 at 3 years and gained 1.2 points per year across the age period studied. Growth-curve analyses of Peabody Picture Vocabulary Test-Revised raw scores revealed an indomethacin-gender effect on initial scores at 3 years, with preterm boys assigned randomly to receive indomethacin scoring, on average, 4.2 points higher than placebo-treated boys. However, the velocity of receptive vocabulary development from 3 to 12 years did not differ for the treatment groups. Children with severe brain injury demonstrated slower gains in skills over time, compared with those who did not suffer severe brain injury. Significant differences in language trajectories were predicted by maternal education and minority status. CONCLUSION: Although indomethacin yielded an initial benefit for preterm boys, this intervention did not alter the developmental trajectory of receptive language scores. Severe brain injury leads to long-term sequelae in language development, whereas a socioeconomically advantaged environment supports better language development among preterm children.

Converging data suggest recovery from injury in the preterm brain. We used functional magnetic resonance imaging (fMRI) to test the hypothesis that cerebral connectivity involving Wernicke's area and other important cortical language regions would differ between preterm (PT) and term (T) control school age children during performance of an auditory language task. Fifty-four PT children (600-1250 g birth weight) and 24 T controls were evaluated using an fMRI passive language task and neurodevelopmental assessments including: the Wechsler Intelligence Scale for Children - III (WISC-III), the Peabody Individual Achievement Test - Revised (PIAT-R) and the Peabody Picture Vocabulary Test - Revised (PPVT-R) at 8 years of age. Neural activity was assessed for language processing and the data were evaluated for connectivity and correlations to cognitive outcomes. We found that PT subjects scored significantly lower on all components of the WISC-III (p<0.009), the PIAT-R Reading Comprehension test (p=0.013), and the PPVT-R (p=0.001) compared to term subjects. Connectivity analyses revealed significantly stronger neural circuits in PT children between Wernicke's area and the right inferior frontal gyrus (R IFG, Broca's area homologue) and both the left and the right supramarginal gyri (SMG) components of the inferior parietal lobules (p=0.02 for all). We conclude that PT subjects employ neural systems for auditory language function at school age differently than T controls; these alterations may represent a delay in maturation of neural networks or the engagement of alternate circuits for language processing.

OBJECTIVES: Our goals were to compare cognitive, language, behavioral, and educational outcomes of preterm children to term controls and to evaluate the impact of neonatal brain injury, indomethacin, and environmental risk factors on intellectual function at 12 years of age. METHODS: A total of 375 children born in 1989-1992 with birth weights of 600 to 1250 g enrolled in the Indomethacin Intraventricular Hemorrhage Prevention Trial and 111 controls were evaluated. Neuropsychometric testing, neurologic examination, and interviews on educational needs were completed. Severe brain injury was defined as the presence of grade 3 to 4 indomethacin intraventricular hemorrhage, periventricular leukomalacia, or severe ventriculomegaly on cranial ultrasound. RESULTS: On the Wechsler Scales of Intelligence for Children, the preterm cohort obtained a full-scale IQ of 87.9 +/- 18.3, verbal IQ of 90.8 +/- 18.9, and performance IQ of 86.8 +/- 17.9. Preterm children obtained scores 6 to 14 points lower than term controls on all psychometric tests after adjustment for sociodemographic factors. On the Clinical Evaluation of Language Fundamentals (test of basic language skills), 22% to 24% of preterm children scored in the abnormal ranges (<70) as opposed to 2% to 4% of controls. Preterm children with and without brain injury required more school services (76% and 44% vs 16%), and support in reading (44% and 28% vs 9%), writing (44% and 20% vs 4%), and mathematics (47% and 30% vs 6%) compared with controls. Preterm children also displayed more behavior problems than their term counterparts. Severe neonatal brain injury was the strongest predictor of poor intelligence. Antenatal steroids, higher maternal education, and 2-parent family were associated with better cognition, whereas minority status incurred a disadvantage. Indomethacin did not affect intellectual function among preterm children. CONCLUSIONS: Preterm children born in the early 1990s, especially those with severe brain injury, demonstrate serious deficits in their neuropsychological profile, which translates into increased use of school services at 12 years.

OBJECTIVES: This study examined risk of maltreatment among children exiting foster care using a statewide sample of children reunified between 2001 and 2004 in Rhode Island. The objectives were: (1) to compare rates of maltreatment following parental reunification for youth in care as a result of maltreatment with those in care for other reasons; and (2) to assess the effects of child, family, and case characteristics on rates of re-maltreatment among children placed in foster care due to maltreatment. METHOD: A longitudinal dataset of all reunified cases was matched with state records of substantiated Child Protective Service (CPS) investigations. Two Cox proportional hazards models were tested. The first model compared rates of subsequent maltreatment for two groups: children in foster care as a result of maltreatment, and those in care for other reasons. The second model investigated the effects of child, family, and case characteristics on re-maltreatment rates for those in care as a result of maltreatment. RESULTS: Children in foster care due to maltreatment were significantly more likely to be maltreated following reunification. Among children in foster care due to maltreatment, factors that raised risk for re-maltreatment included a previous foster care placement, exiting care from a non-relative foster home, and removal due to neglect. Older adolescents had lower rates of re-maltreatment than infants. Child neglect was the primary type of recurrent maltreatment that occurred following reunification. CONCLUSIONS: Supports are needed for families about to be reunified, particularly when the removal was prompted by incidents of abuse or neglect. Incidents of neglect are particularly likely and appropriate services should specifically target factors contributing to neglect. Cases involving youth with a history of repeated foster care placement or in which non-relative placements are utilized may need additional supports. PRACTICE IMPLICATIONS: This study suggests that services should be developed to minimize the risk for recurrent maltreatment following reunification. Services would be most useful for high-risk cases prior to reunification and during the first year following reunification. Understanding the risks associated with maltreatment will help guide development of appropriate interventions.

OBJECTIVE: Although preterm very low birth weight infants have a high prevalence of neuroanatomical abnormalities when evaluated at term-equivalent age, patterns of brain growth in prematurely born infants during school age and adolescence remain largely unknown. Our goal was to test the hypothesis that preterm birth results in long-term dynamic changes in the developing brain. METHODS: We performed serial volumetric MRI studies at ages 8 and 12 years in 55 preterm infants born weighing 600 to 1250 g and 20 term control children who participated in the follow-up component of a prospective, randomized, placebo-controlled intraventricular hemorrhage prevention study. RESULTS: Total brain volumes increased 2% to 3% between the ages of 8 and 12 years for both preterm and term children. These changes involved reductions in cerebral gray matter while white matter increased. Between 8 and 12 years of age, preterm subjects experienced a 2% decrease in left cerebral gray matter compared with a 10% reduction in left cerebral gray for term controls. For right cerebral gray matter, preterm children experienced a 3% decrease in volume between years 8 and 12, compared with 9% for term controls (group-by-time). In contrast, preterm subjects had a 10% increase in cerebral white matter volumes bilaterally between ages 8 and 12 years, compared with >26% increases for both hemispheres for term controls. Significant differences in regional volume changes between study groups were found in bilateral temporal gray and in parietal white matter. CONCLUSIONS: Preterm birth continues to perturb the trajectory of cerebral development during late childhood and early adolescence with preterm children, showing both lower gray matter reduction and less white matter gain over time compared with term control subjects.

Recent data suggest recovery of language systems but persistent structural abnormalities in the prematurely born. We tested the hypothesis that subjects who were born prematurely develop alternative networks for processing language. Subjects who were born prematurely (n = 22; 600-1250 g birth weight), without neonatal brain injury on neonatal cranial ultrasound, and 26 term control subjects were examined with a functional magnetic resonance imaging (fMRI) semantic association task, the Wechsler Intelligence Scale for Children-III (WISC-III) and the Clinical Evaluation of Language Fundamentals (CELF). In-magnet task accuracy and response times were calculated, and fMRI data were evaluated for the effect of group on blood oxygen level dependent (BOLD) activation, the correlation between task accuracy and activation and the functional connectivity between regions activating to task. Although there were differences in verbal IQ and CELF scores between the preterm (PT) and term control groups, there were no significant differences for either accuracy or response time for the in-magnet task. Both groups activated classic semantic processing areas including the left superior and middle temporal gyri and inferior frontal gyrus, and there was no significant difference in activation patterns between groups. Clear differences between the groups were observed in the correlation between task accuracy and activation to task at P < 0.01, corrected for multiple comparisons. Left inferior frontal gyrus correlated with accuracy only for term controls and left sensory motor areas correlated with accuracy only for PT subjects. Left middle temporal gyri correlated with task accuracy for both groups. Connectivity analyses at P < 0.001 revealed the importance of a circuit between left middle temporal gyri and inferior frontal gyrus for both groups. In addition, the PT subjects evidenced greater connectivity between traditional language areas and sensory motor areas but significantly fewer correlated areas within the frontal lobes when compared to term controls. We conclude that at 12 years of age, children born prematurely and children born at term had no difference in performance on a simple lexical semantic processing task and activated similar areas. Connectivity analyses, however, suggested that PT subjects rely upon different neural pathways for lexical semantic processing when compared to term controls. Plasticity in network connections may provide the substrate for improving language skills in the prematurely born.

OBJECTIVES: To more precisely examine regional and subregional microstructural brain changes associated with preterm birth. STUDY DESIGN: We obtained brain volumes from 29 preterm children, age 12 years, with no ultrasound scanning evidence of intraventricular hemorrhage or cystic periventricular leukomalacia in the newborn period, and 22 age- and sex-matched term control subjects. RESULTS: Preterm male subjects demonstrated significantly lower white matter volumes in bilateral cingulum, corpus callosum, corticospinal tract, prefrontal cortex, superior and inferior longitudinal fasciculi compared with term male subjects. Gray matter volumes in prefrontal cortex, basal ganglia, and temporal lobe also were significantly reduced in preterm male subjects. Brain volumes of preterm female subjects were not significantly different from those of term female control subjects. Voxel-based morphometry results were not correlated with perinatal variables or cognitive outcome. Higher maternal education was associated with higher cognitive performance in preterm male subjects. CONCLUSIONS: Preterm male children continue to demonstrate abnormal neurodevelopment at 12 years of age. However, brain morphology in preterm female children may no longer differ from that of term female children. The neurodevelopmental abnormalities we detected in preterm male subjects appear to be relatively diffuse, involving multiple neural systems. The relationship between aberrant neurodevelopment and perinatal variables may be mediated by genetic factors, environmental factors, or both reflected in maternal education level.

OBJECTIVE: The goal was to use diffusion tensor imaging to test the hypothesis that prematurely born children demonstrate long-term, white matter, microstructural differences, relative to term control subjects. METHODS: Twenty-nine preterm subjects (birth weight: 600-1250 g) without neonatal brain injury and 22 matched, term, control subjects were evaluated at 12 years of age with MRI studies, including diffusion tensor imaging and volumetric imaging; voxel-based morphometric strategies were used to corroborate regional diffusion tensor imaging results. Subjects also underwent neurodevelopmental assessments. RESULTS: Neurodevelopmental assessments showed significant differences in full-scale, verbal, and performance IQ and Developmental Test of Visual Motor Integration scores between the preterm and term control subjects. Diffusion tensor imaging studies demonstrated widespread decreases in fractional anisotropy (a measure of fiber tract organization) in the preterm children, compared with the control subjects. Regions included both intrahemispheric association fibers subserving language skills, namely, the right inferior frontooccipital fasciculus and anterior portions of the uncinate fasciculi bilaterally, and the deep white matter regions to which they project, as well as the splenium of the corpus callosum. These changes in fractional anisotropy occurred in subjects with significant differences in frontal, temporal, parietal, and deep white matter volumes. Fractional anisotropy values in the left anterior uncinate correlated with verbal IQ, full-scale IQ, and Peabody Picture Vocabulary Test-Revised scores for preterm male subjects. In addition, preterm male subjects were found to have the lowest values for fractional anisotropy in the right anterior uncinate fasciculus, and fractional anisotropy values in that region correlated with both verbal IQ and Peabody Picture Vocabulary Test-Revised scores for the preterm groups; these findings were supported by changes identified with voxel-based morphometric analyses. CONCLUSIONS: Compared with term control subjects, prematurely born children with no neonatal ultrasound evidence of white matter injury manifest changes in neural connectivity at 12 years of age.

Standardized approaches to the treatment of neonatal seizures remain undeveloped. We assessed the type and number of anticonvulsants selected, blood levels attained, and postdischarge anticonvulsant treatment of neonatal seizures among five neonatal intensive care units in the United States between 2000-2003. Almost all of the 480 neonates (94%) with seizures were treated, initially with phenobarbital (82%), lorazepam (9%), phenytoin (2%), other anticonvulsants (1%), or a combination of the first two drugs (6%). While the majority of neonates were treated with one drug (59%), the number of anticonvulsants varied (P<0.0001), as did the peak serum phenobarbital levels (P<0.0001). The majority (75%) of survivors received anticonvulsant treatment after discharge. These neonates were more likely to have had abnormal electroencephalography or brain imaging, or to have needed a second anticonvulsant, compared with neonates whose drug therapy was discontinued. Anticonvulsant therapy is used in the majority of neonates with seizures, mostly with phenobarbital, and treatment is continued beyond discharge. The observed wide therapeutic variability may reflect a lack of standardized diagnostic and treatment approaches, particularly for seizures refractory to initial phenobarbital therapy. Trials of anticonvulsants with long-term neurodevelopmental follow-up are needed to develop evidence-based treatment guidelines.

INTRODUCTION: This study examines child, family, and case characteristics that impact rates of re-referral to Child Protective Services (CPS) using data on all closed CPS investigations for the state of Rhode Island between 2001 and 2004. METHOD: A longitudinal dataset of all referrals to CPS was created using state submissions to the National Child Abuse and Neglect Data System (NCANDS). After excluding children whose initial CPS investigation resulted in removal from the home, a Cox proportional hazards model was tested to examine factors impacting the likelihood of re-referral. RESULTS: Consistent with other research in this area, the initial 6-month period following case disposition is the period of greatest risk of re-referral. Approximately 13% of cases experienced a recurrent allegation during the first 6-month period; an additional 14% experienced a re-referral over the following 12-month period; 7% during the next 12-month period. Family poverty was the strongest predictor of re-referral, though a number of child and case characteristics were significantly related to recurrence. Cases that were substantiated at index were significantly less likely to result in a new allegation, though substantiated cases of physical abuse or those receiving post-investigation services were at higher risk. CONCLUSIONS: Children from families facing multiple stressors (e.g., low SES, parental substance abuse child disability) are at highest risk of re-referral to CPS and may benefit from the development of preventive services targeted immediately following case closings within CPS.

Research has established the coincidence of parental alcohol and other drug (AOD) use and child maltreatment, but few studies have examined the placement experiences and outcomes of children removed because of parental AOD use. The present study examines demographic characteristics and placement experiences of children removed from their homes because of parental AOD use (n = 1,333), first in comparison to the remaining sample of children in foster care (n = 4,554), then in comparison to a matched comparison group of children in foster care who were removed for other reasons (n = 1,333). Relative to the comparison sample, children removed for parental AOD use are less likely to experience co-occurring removal because of neglect and physical or sexual abuse and are more likely to be placed in relative foster care. In addition, these children remain in care longer, experience similar rates of reunification, and have significantly higher rates of adoption.
