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

Ultrasound-Guided Subclavian Vein Cannulation in Low Birth Weight Neonates.

Pediatr Crit Care Med 2017 02;18(2):172-175

1Pediatric and Neonatal Intensive Care Unit, Paris South University Hospitals, Assistance Publique Hôpitaux de Paris, Le Kremlin-Bicêtre, Paris, France. 2School of Medicine, Paris South University, Le Kremlin-Bicêtre, Paris, France. 3Institute of Integrative Biology of the Cell-UMR 9198, Paris Saclay University, Gif-sur-Yvette, Paris, France. 4Espace Ethique/IDF, Saint Louis University Hospital, Assistance Publique Hôpitaux de Paris, Paris, France.

Objectives: Central venous access in critically ill, small infants remains technically challenging even in experienced hands. Several vascular accesses exist, but the subclavian vein is often preferred for central venous catheter insertion in infants where abdominal malformation and/or closure of the vein preclude the use of umbilical venous catheters, as catheterization of the subclavian vein is easier in very short necks than the internal jugular vein for age-related anatomical reasons. The subclavian vein approach is yet relatively undescribed in low birth weight infants (i. Read More

Hydrogen sulfide suppresses angiotensin II-stimulated endothelin-1 generation and subsequent cytotoxicity-induced endoplasmic reticulum stress in endothelial cells via NF-κB.

Mol Med Rep 2016 Nov 12;14(5):4729-4740. Epub 2016 Oct 12.

Department of Cardiology/Cardiac Catheterization Laboratory, Second Xiangya Hospital, Central South University, Changsha, Hunan 410011, P.R. China.

The effects of hydrogen sulfide (H2S) and the nuclear factor κB (NF-κB) signaling pathway in angiotensin II (AngII)-induced endothelin-1 (ET-1) expression and subsequent cytotoxicity remain unclear. The present study aimed to investigate the hypothesis that H2S protects human umbilical vein endothelial cells (HUVECs) against AngII‑stimulated ET‑1 generation and subsequent cytotoxicity‑induced endoplasmic reticulum stress via the NF‑κB signaling pathway. The results of the present study demonstrated that AngII significantly upregulated the expression levels of ET‑1, glucose‑regulated protein 78, CCAAT‑enhancer‑binding protein homologous protein, phosphorylated (p)‑p65 and inducible nitric oxide synthase; stimulated nitric oxide production; suppressed the expression and activity of cystathionine-γ-lyase (CSE), a H2S synthetase; and decreased cell viability.

Term Neonate With Liver Laceration, Obstructive Uropathy, and Ascites-Secondary to Extravasation of Total Parenteral Nutrition: A Complication of Malpositioned Umbilical Venous Catheter.

Glob Pediatr Health 2016 12;3:2333794X16670494. Epub 2016 Oct 12.

Texas Tech University Health Sciences Center, Amarillo, TX, USA.

We report a rare, but serious, complication of a malpositioned umbilical venous catheter in a term male infant who developed laceration, hematoma, and necrosis of liver, ascites, and left-sided obstructive uropathy secondary to extravasation of total parenteral nutrition. Abdominal paracentesis confirmed the presence of parenteral nutrition in the peritoneal cavity. Although, the umbilical venous catheterization is a common intravenous access used in neonatal intensive care units, judicious continued monitoring of its use should be practiced to avoid serious complications.

Endothelial repair in stented arteries is accelerated by inhibition of Rho-associated protein kinase.

Cardiovasc Res 2016 12 26;112(3):689-701. Epub 2016 Sep 26.

Department of Infection, Immunity and Cardiovascular Disease, University of Sheffield, Sheffield S10 2RX, UK

Aims: Stent deployment causes endothelial cells (EC) denudation, which promotes in-stent restenosis and thrombosis. Thus endothelial regrowth in stented arteries is an important therapeutic goal. Stent struts modify local hemodynamics, however the effects of flow perturbation on EC injury and repair are incompletely understood. Read More

Turk Kardiyol Dern Ars 2016 Sep;44(6):521-3

Department of Pediatric Cardiology, İstanbul University, İstanbul Faculty of Medicine, İstanbul, Turkey.

Balloon valvuloplasty is an effective therapy for severe congenital aortic valve stenosis, with mild aortic insufficiency and minimal intermediate-term restenosis. No consensus currently exists regarding optimal vascular approach for balloon dilatation in newborns with critical or severe aortic valve stenosis. Critical aortic valve stenosis in newborns must be treated promptly and effectively. Read More

Positioning newborns on their back or right side for umbilical venous catheter insertion.

Acta Paediatr 2016 Oct 12;105(10):e443-7. Epub 2016 Aug 12.

Department of Neonatology, The National Maternity Hospital, Dublin, Ireland.

Aim: Newborns are placed supine for umbilical venous catheter insertion, and catheter tip position is confirmed with X-ray. Umbilical venous catheters are considered correctly positioned when the tip is in the inferior vena cava; however, frequently, the catheter tip enters the portal venous circulation. We wished to determine whether placing infants on their right side, rather than on the back, for umbilical venous catheter insertion results in more correctly placed catheters. Read More

Objective: Drug-eluting coronary stents reduce restenosis rate and late lumen loss compared with bare-metal stents; however, drug-eluting coronary stents may delay vascular healing and increase late stent thrombosis. The peroxisome proliferator-activated receptor-delta (PPARδ) exhibits actions that could favorably influence outcomes after drug-eluting coronary stents placement.

Approach And Results: Here, we report that PPARδ ligand-coated stents strongly reduce the development of neointima and luminal narrowing in a rabbit model of experimental atherosclerosis. Read More
