Background: Racial differences in carotid intima-media thickness (cIMT) have been suggested to be associated with the disproportionally high prevalence of cardiovascular disease in black adults. The objective of this study was to evaluate the effects of cardiovascular risk factors on the racial differences seen in cIMT in obese children.
Methods: Obese subjects aged 4 to 21 years were recruited prospectively.
Surfactant treatment has become the standard of care in premature infants with respiratory distress syndrome (RDS). Pulmonary hemorrhage, pulmonary edema, pneumonia, and atelectasis have been shown to liberate inflammatory mediators and plasma proteins, which damage type II pneumocytes and inactivate surfactant. These disease processes may, therefore, lead to a secondary surfactant inactivation or deficiency, which can be an unrecognized cause of respiratory decompensation after initial recovery from RDS in this vulnerable population.
