Clinical risk factors for preterm birth and evaluating maternal psychology in the postpartum period.

Background: Although the specific pathogenesis of preterm birth (PTB) has not been thoroughly clarified, it is known to be related to various factors, such as pregnancy complications, maternal socioeconomic factors, lifestyle habits, reproductive history, environmental and psychological factors, prenatal care, and nutritional status. PTB has serious implications for newborns and families and is associated with high mortality and complications. Therefore, the prediction of PTB risk can facilitate early intervention and reduce its resultant adverse consequences.

[Diagnostic Value of Cystain C in Contrast Associated Acute Kidney Injury after Transcatheter Closure for Children with Congenital Heart Disease].

Objectives: To investigate the diagnostic value of cystain C (SCys-C) in contrast associated acute kidney injury (AKI) after transcatheter closure for children with congenital heart disease.

Methods: There were 128 children with congenital heart disease (interventricular septal defect or patent ductus arteriosus) underwent transcatheter closure in West China Second University Hospital during 2013. Blood urea nitrogen (BUN), serum creatinine (SCr) and SCys-C were examined before surgery and at 24 and 48 h after surgery.
