Intraoperative monitoring of stroke volume variation versus central venous pressure in laparoscopic liver surgery: a randomized prospective comparative trial.

HPB : the official journal of the International Hepato Pancreato Biliary Association Nov 17, 2015
BACKGROUND: Central venous pressure (CVP) is used as a marker of cardiac preload to control intraoperative blood loss in open hepatectomies, while its reliability in laparoscopy is less certain. The aim of this randomized prospective trial was to eva...

Pregnancy risk factors in autism: a pilot study with artificial neural networks.

Pediatric research Nov 2, 2015
BACKGROUND: Autism is a multifactorial condition in which a single risk factor can unlikely provide comprehensive explanation for the disease origin. Moreover, due to the complexity of risk factors interplay, traditional statistics is often unable to...
