Umbilical catheters as vectors for generalized bacterial infection in premature infants regardless of antibiotic use.

J Med Microbiol 2019 Sep 5;68(9):1306-1313. Epub 2019 Jul 5.

Neonatal Intensive Care Unit, Department of Pediatrics, Jagiellonian University Medical College, Kraków, Poland.

Umbilical catheterization offers unique vascular access that is only possible in the neonatal setting due to unobstructed umbilical vessels from foetal circulation. With the cut of the umbilical cord, two arteries and a vein are dissected, allowing quick and painless catheterization of the neonate. Unfortunately, keeping the umbilical access sterile is challenging due to its mobility and necrosis of the umbilical stump, which makes it a perfect model for vessel catheter colonization analysis.

Technical feasibility of umbilical cannulation in midgestation lambs supported by the EXTra-uterine Environment for Neonatal Development (EXTEND).

Artif Organs 2019 Dec 28;43(12):1154-1161. Epub 2019 Jul 28.

Center for Fetal Research, Department of Surgery, Children's Hospital of Philadelphia Research Institute, Philadelphia, Pennsylvania.

EXTEND (EXTra-uterine Environment for Neonatal Development) is a novel system for supporting extremely premature infants that replicates in utero conditions by maintaining a sterile fluid environment and providing gas exchange via a pumpless arteriovenous oxygenator circuit connected to the umbilical vessels. Target gestational age (GA) for EXTEND support in human infants is 23-27 weeks, when immature lungs are most susceptible to injury in the setting of air ventilation. We previously demonstrated physiologic support of premature lambs cannulated at 105-117 days GA (lungs developmentally analogous to the 23-27 week GA human infant) for up to 28 days on EXTEND.

Balloon atrial septostomy at the bedside versus the catheterisation laboratory.

Cardiol Young 2019 Mar 28;29(3):454. Epub 2019 Jan 28.

Department of Cardiology,Sree Chitra Tirunal Institute for Medical Sciences and Technology,Thiruvananthapuram,Kerala,India.

A shorter umbilical venous approach provides an opportunity for balloon atrial septostomy in the younger neonate as opposed to those who present at the end of first week of life. However, the ideal choice of access for a bedside balloon atrial septostomy is not well established. Wouldn't prostaglandin infusion be a safer option for transport of babies with dextro-transposition in the neonatal period, when the arterial duct can be kept open? A prenatal diagnosis of dextro-transposition facilitates monitoring and planning of septostomy in the early neonatal period explaining why babies underwent bedside procedures more often. Read More

Antenatal exposure to nonsteroidal anti-inflammatory drugs and risk of neonatal hypertension.

J Clin Hypertens (Greenwich) 2018 09 27;20(9):1334-1341. Epub 2018 Jul 27.

Perinatal Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are used as tocolytics, which are medications that suppress uterine contractions for preterm birth prevention. Their effect on cerebral/systemic vascular beds poses the question of whether antenatal NSAID exposure is associated with neonatal hypertension. We performed a retrospective case-control study in a tertiary neonatal intensive care unit, including 40 hypertension cases (hospitalized neonates ≥ 35 weeks with systolic BP > 100 mm Hg on three consecutive days) compared to 134 controls matched by gestational age at delivery, plurality, and delivery date.

Arterioscler Thromb Vasc Biol 2018 06 5;38(6):1368-1380. Epub 2018 Apr 5.

From the Center for Hemostasis and Thrombosis Research, Tufts Medical Center, Tufts University School of Medicine, Boston, MA (R.R., T.H., G.K., E.K.F., S.E.T., A.S., L.C., A.K.)

Objective: Protease-activated receptor-1 (PAR1) is classically activated by thrombin and is critical in controlling the balance of hemostasis and thrombosis. More recently, it has been shown that noncanonical activation of PAR1 by matrix metalloprotease-1 (MMP1) contributes to arterial thrombosis. However, the role of PAR1 in long-term development of atherosclerosis is unknown, regardless of the protease agonist. Read More

Postnatal dilatation of umbilical cord vessels and its impact on wall integrity: Prerequisite for the artificial placenta.

Int J Artif Organs 2018 Jul 22;41(7):393-399. Epub 2018 Mar 22.

1 Division of Neonatology, Department of Pediatrics, McMaster University, Hamilton, ON, Canada.

Introduction: A lung assist device, which acts as an artificial placenta, can provide additional gas exchange for preterm and term newborns with respiratory failure. The concept of the lung assist device requires a large bore access via umbilical vessels to allow pumpless extracorporeal blood flow rates up to 30 mL/kg/min. After birth, constricted umbilical vessels need to be reopened for vascular access. Read More

Umbilical cannulation optimizes circuit flows in premature lambs supported by the EXTra-uterine Environment for Neonatal Development (EXTEND).

J Physiol 2018 05 2;596(9):1575-1585. Epub 2018 Mar 2.

Center for Fetal Research, Department of Surgery.

Key Points: Bronchopulmonary dysplasia is a disease of extreme prematurity that occurs when the immature lung is exposed to gas ventilation. We designed a novel 'artificial womb' system for supporting extreme premature lambs (called EXTEND) that obviates gas ventilation by providing oxygen via a pumpless arteriovenous circuit with the lamb submerged in sterile artificial amniotic fluid. In the present study, we compare different arteriovenous cannulation strategies on EXTEND, including carotid artery/jugular vein (CA/JV), carotid artery/umbilical vein (CA/UV) and umbilical artery/umbilical vein (UA/UV).
