Are there ethnic disparities in risk of preterm birth among infants born with congenital heart defects?
The increased risk of PTB among SGA and AGA NH-Black infants with CHDs is not explained by the overall disparities in risk of PTB between NH-Blacks and NH-Whites. Additional studies are needed to determine the specific subtypes of CHD for which these relationships are present and if these findings are seen among infants with other birth defects.
These results suggest that low-dose ethanol attenuates the gut I/R-induced hepatic microvascular dysfunction and sequential liver injury by increasing sinusoidal NO levels.
