Mortality and Neonatal Morbidity Among Infants 501 to 1500 Grams From 2000 to 2009
Infants weighing 501 to 1500 g are at high risk for mortality and for neonatal morbidities associated with both short- and long-term adverse consequences.
Mortality and major neonatal morbidity in survivors decreased for infants 501 to 1500 g between 2000 and 2009. However, in 2009, a high proportion of these infants still either died or survived after experiencing ≥1 major neonatal morbidity.
Prevalence of Cardiovascular Disease Risk Factors Among US Adolescents, 1999-2008
Overweight and obese children have a higher prevalence of several cardiovascular disease (CVD) risk factors. There is growing evidence demonstrating that CVD risk factors present during childhood persist into adulthood.
US adolescents had no significant change in prehypertension/hypertension and borderline-high/ high low-density lipoprotein cholesterol prevalence from 1999-2000 to 2007-2008; however, prediabetes/diabetes increased by 14%.
Predictors of Survival in Children Born With Down Syndrome: A Registry-Based Study
Survival of children born with Down syndrome has been improving, but few studies have used population-based data to examine the influence of fetal and maternal characteristics on survival.
This study examined predictors of survival for children born with Down syndrome using population-based data from the UK Northern Congenital Abnormality Survey and shows that year of birth, gestational age, birth weight, and presence of additional anomalies influence survival status.
Prevalence of Retinal Hemorrhages in Critically Ill Children
The association of retinal hemorrhages (RHs) with abusive head trauma (AHT) is robust; 46% to 100% RHs are reported in AHT. There is potential selection bias with risk of circular reasoning because the majority of studies describing RH focus on AHT.
This is the first prospective observational study defining prevalence and distribution of RH in critically ill children excluding those with AHT. Severe multilayered RH were rare and observed in children with accidental fatal head injury, severe coagulopathy, severe sepsis, or a combination of these factors.
Transient Neonatal Hypocalcemia: Presentation and Outcomes
Late-onset hypocalcemia is common in neonates, often presents with seizures or tetany, and is often attributed to transient hypoparathyroidism.
Late-onset hypocalcemia in neonates is often a sign of coexisting vitamin D deficiency and hypomagnesemia and is readily managed with therapy of limited duration, and neonates presenting with tetany or seizures due to hypocalcemia are unlikely to benefit from neuroimaging studies.
Youth violence and alcohol misuse are a preventable public health problem. Previous studies have demonstrated the efficacy of brief interventions in the emergency department (ED) in reducing alcohol misuse and related consequences among older adolescents and adults.
This study supports the efficacy of brief interventions in the ED in reducing peer aggression and victimization 12 months after ED visit. The previous reductions in alcohol consequences noted at 6 months follow-up were not sustained at 12 months.
Missed Opportunities in the Referral of High-Risk Infants to Early Intervention
Neonatal follow-up programs are designed in part to identify developmental delays among high-risk infants after NICU hospitalization and make referrals to state-funded early intervention. Early intervention has been shown to benefit children with developmental delays.
Many high-risk infants demonstrating developmental delays at neonatal follow-up programs are not referred to early intervention. Subspecialty clinics share responsibility with the medical home in referring children from birth through three years with developmental problems to early intervention services.
Effect of a Single Inhalation of Laninamivir Octanoate in Children With Influenza
A single inhalation of laninamivir octanoate has previously been shown to be as effective as repeated doses of zanamivir in vitro and in vivo, but it is not known whether this is also the case for children.
Median time to fever resolution was not significantly different between laninamivir octanoate and zanamivir for pediatric patients with influenza. The severity of influenza symptoms and the frequency of complications were similar in the 2 groups.
Hypertonic Saline and Acute Wheezing in Preschool Children
Most acute wheezing episodes in preschool children are associated with rhinovirus, which decreases extracellular adenosine triphosphate levels, leading to airway surface liquid dehydration and submucosal edema, which cause failure of mucus clearance. These children respond poorly to available treatments.
Hypertonic saline inhalation, a pro-airway surface liquid hydration therapy, significantly decreases both length of stay by 33% (1 day) and the absolute risk of hospitalization by 30% in preschool children presenting with acute wheezing episode to the emergency department.
Childhood Cancer Incidence Trends in Association With US Folic Acid Fortification (1986-2008)
The hypothesis that maternal prenatal folic acid lowers risk for childhood malignancy in offspring is supported by experimental and epidemiologic evidence, including 2 Canadian ecologic studies that showed inverse associations for some cancer types in the very young.
Examining Surveillance Epidemiology and End Results Program data, a decrease in the incidence of some childhood cancers (Wilms tumor, primitive neuroectodermal tumors) was observed in those 5 years after mandatory US folic acid fortification, with stronger effects detected in infants.
Neurocognitive Phenotype of Isolated Methylmalonic Acidemia
Isolated methylmalonic acidemia, one of the most common inborn errors of organic acid metabolism, is known to be associated with variably impaired intellectual functioning and severe biochemical and clinical abnormalities. However, the neurocognitive outcomes have yet to be fully described.
This research defines the neurocognitive phenotype of isolated methylmalonic acidemia and identifies processing speed as a specific impairment. Clinical, biochemical, and molecular genetic covariates were explored. A history of hyperammonemia at diagnosis was found to correlate with poorer cognitive outcomes.
Risky Music-Listening Behaviors and Associated Health-Risk Behaviors
Traditional health-risk behaviors, such as problem drinking, smoking, marijuana use, and unsafe sexual behavior are interrelated and not isolated events in the life of adolescents. New health-risk behaviors are emerging: risky music-listening behaviors, which may induce hearing loss.
