BACKGROUND: The antenatal diagnosis of a combined esophageal atresia without tracheoesophageal fistula and duodenal atresia with or without gastric perforation is a rare occurrence. These diagnoses are difficult and can be suspected on ultrasound by nonspecific findings including a small stomach and polyhydramnios. Fetal magnetic resonance imaging adds significant anatomical detail and can aid in the diagnosis of these complicated cases. Upon an extensive literature review, there are no reports documenting these combined findings in a twin pregnancy...

BACKGROUND: Arterial blood pressure-induced shear stress causes endothelial cell apoptosis and inflammation in vein grafts after coronary artery bypass grafting. As the inflammatory protein type IIA secretory Phospholipase A2 (sPLA2-IIA) has been shown to progress atherosclerosis, we hypothesized a role for sPLA2-IIA herein. MATERIALS AND METHODS: The effects of PX-18, an inhibitor of both sPLA2-IIA and apoptosis, on residual endothelium and the presence of sPLA2-IIA were studied in human saphenous vein segments (n=6) perfused at arterial blood pressure with autologous blood for 6 hours...

Synthetic artificial vascular grafts have exhibited low patency rate and severe neointimal hyperplasia in replacing small-caliber arteries (<6 mm) because of their failure to generate a functional endothelium. In this study, small-caliber (2.0 mm) electrospun poly(ε-caprolactone) (PCL) vascular grafts were modified with a fusion protein VEGF-HGFI which consists of the class I hydrophobin (HGFI) and vascular endothelial growth factor (VEGF), via hydrophobic interactions. Immunofluorescence staining with the anti-VEGF antibody showed that VEGF-HGFI formed a protein layer on the surface of fibers in the grafts...

Fetal growth restriction (FGR) is a common complication of pregnancy, principally caused by suboptimal placental function, and is associated with high rates of perinatal mortality and morbidity. Clinical studies suggest that the time of onset of placental insufficiency is an important contributor towards the neurodevelopmental impairments that are evident in children who had FGR. It is however currently unknown how early-onset and late-onset FGR differentially affect brain development. The aim of this study was to examine neuropathology in early-onset and late-onset FGR fetal sheep and to determine whether they differentially alter brain development...

Qi Li, Xin-Hua Wu, Wei-She Zhang
RATIONALE: The preferred method for multifetal pregnancy reduction (MFPR) is a transabdominal intrathoracic or intracranial injection of potassium chloride (KCl). However, in monochorionic multiple pregnancies (MMPs), especially in monoamnionic multifetal pregnancies, selective feticide by this method is often associated with miscarriage of the remaining fetuses. Selective fetal reduction in MMPs by blood flow ablation using radiofrequency ablation or fetoscopic laser surgery may improve survival of the remaining fetus...

A 20:1 combination of cafedrine:theodrenaline (Akrinor®) is widely used in Germany for the treatment of hypotensive states during anesthesia and in emergency medicine. Although this drug formulation has been available since 1963, there are few studies relating to its use and many of the data are only available in German. In this article, we summarize the available data and propose mechanisms for the effects of cafedrine/theodrenaline on cardiac muscle cells and vascular smooth muscle cells. Cafedrine/theodrenaline leads to a rapid increase in mean arterial pressure that is characterized by increased cardiac preload, stroke volume, and cardiac output...

Prematurity is a risk factor for hypertension, vascular stiffness, nephron deficit and adult onset cardiorenal disease. The vascular tree and kidneys share morphogenic drivers that promote maturation in utero before 36 weeks of gestation. Vascular elastin accrual terminates after birth leaving collagen to promote vascular stiffness. Our objective was to determine if the histomorphometry of the umbilical artery, an extension of the aorta, parallels nephron mass across gestational age groups. From a cohort of 54 newborns, 32 umbilical cord specimens were adequate for evaluation...

Prophylactic vasopressor administration is commonly recommended to reduce maternal hypotension during spinal anaesthesia for caesarean section. Metaraminol has undergone limited investigation in obstetric anaesthesia for this purpose, particularly in comparison with phenylephrine. In this multicentre, randomised, double-blind, non-inferiority study, we compared prophylactic phenylephrine or metaraminol infusions, started immediately after spinal anaesthesia, in 185 women who underwent elective caesarean section...
