Review Multicenter Study Comparative Study
Perinatal care at the threshold of viability: an international comparison of practical guidelines for the treatment of extremely preterm births.
Over the last 2 decades, the survival rate of infants born at < or = 25 weeks of gestation has increased; however, significant morbidity and disability persist. The commitment for their care gives rise to a variety of complex medical, social, and ethical aspects. Decision-making is a crucial issue that involves the infant, the family, health care providers, and society. ⋯ We found that many scientific societies and professional organizations have issued guidelines that address the recommendations for the care of these fetuses/neonates although to varying degrees. In this article we compare different approaches and assess the scientific grounds of the specific recommendations. With current standards, intensive care is generally considered justifiable at > or = 25 weeks, compassionate care at < or = 22 weeks, and an individual approach at 23 to 24 weeks, consistent with the parents' wishes and the infant's clinical conditions at birth.

Multicenter Study
Managing attention-deficit/hyperactivity disorder in primary care: a systematic analysis of roles and challenges.
This study was designed to investigate the perceptions of primary care providers about their roles and the challenges of managing attention-deficit/hyperactivity disorder and to evaluate differences between providers who serve families primarily from urban versus suburban settings. ⋯ Primary care providers believe that it is highly appropriate for them to have a role in the management of attention-deficit/hyperactivity disorder. Feasibility issues were particularly salient related to assessing attention-deficit/hyperactivity disorder and providing mental health care. The findings highlight the need not only for additional training of primary care providers but also for practice-based resources to assist with school communication and collaboration with mental health agencies, especially in urban practices.

Children with central venous catheters and suspected bloodstream infection are often hospitalized for 48 hours to receive empiric antibiotic therapy pending blood-culture results. Continuous monitoring blood-culture systems allow for more rapid detection of bloodstream infection than previous blood-culture systems, a feature that may facilitate earlier determination of the true presence or absence of bloodstream infection and shorten empiric antibiotic therapy and duration of hospitalization. ⋯ The time to blood-culture positivity depends on bacterial category. Bloodstream infections caused by gram-negative bacteria are detected most quickly. Our data suggest that discontinuation of empiric antibiotic coverage may be warranted in clinically stable children with central venous catheters if the blood-culture results remain negative 24 to 36 hours after collection.

Neonatal respiratory distress syndrome is associated with intrahepatic cholestasis of pregnancy, and bile acids may play a major role in neonatal bile acid pneumonia. Our aim was to demonstrate the bile acid presence in the bronchoalveolar lavage fluid of neonates affected by respiratory distress syndrome who were born from intrahepatic cholestasis of pregnancy and to investigate bile acid mechanisms of action in acute lung injury. ⋯ Bile acids are detectable in the bronchoalveolar lavage fluid of newborns from intrahepatic cholestasis of pregnancy affected by respiratory distress syndrome. Elevated serum bile acid levels in these infants allow us to hypothesize that bile acid reaches the lung after an uptake from the circulation. These findings strongly support a role for bile acid in causing bile acid pneumonia.

The goal was to investigate the clinical impact of 3 early management practice changes for infants of < or = 1000 g. ⋯ Successful early management of extremely preterm infants with surfactant treatment followed by continuous positive airway pressure treatment at delivery, lowered oxygen saturation goals, and early amino acid supplementation is possible and is associated with reductions in the incidence and severity of bronchopulmonary dysplasia.
