Prenatal Ultrasound Findings of Circumvallate Placenta and Pregnancy Outcomes.

Objective: Circumvallate placenta has a suggested association with adverse pregnancy outcomes (antenatal bleeding, placental abruption, preterm birth, emergency cesarean, small for gestational age infants, and stillbirth). The aim was to determine if prenatal diagnosis of circumvallate placenta is associated with these adverse pregnancy outcomes.

Study Design: Pregnancies with a singleton gestation prenatally diagnosed with circumvallate placenta between January 1, 2012 and March 31, 2021 were identified.

Cerebrospinal fluid findings in infants with pertussis or parapertussis(1)).

Background: Pertussis has been increasing in frequency and can cause protean manifestation in infants, often resulting in extensive laboratory evaluation.

Methods: We examined the prevalence of cerebrospinal fluid (CSF) anomalies in infants with pertussis and parapertussis over a 5-year period.

Results: In total, 239 of 1489 children (16.

Paraoxonase-1 deficiency in mice predisposes to vascular inflammation, oxidative stress, and thrombogenicity in the absence of hyperlipidemia.

Background: Paraoxonase-1 is a polymorphic enzyme that is strongly associated with circulating high-density lipoproteins. The absence of paraoxonase-1 in mice has been shown to promote diet-induced atherosclerosis. As paraoxonase-1 has been recently shown to be a lactonase, its functional role remains to be fully elucidated.
