Post-ROSC peripheral perfusion index discriminates 30-day survival after out-of-hospital cardiac arrest.

Background: Prognostication after an out-of-hospital cardiac arrest (OHCA) remains a challenge. The peripheral-derived perfusion index (PI) is a simple and non-invasive way to assess perfusion. We sought to assess whether the PI was able to discriminate the prognosis of patients resuscitated from an OHCA.

Positioning issues of spinal surgery during pregnancy.

Background: Albeit rarely, different spinal pathologies may require surgical treatment during pregnancy. The management of such cases poses a series of challenges, starting with adequate body positioning.

Objective: To illustrate limits and indications of the different surgical positioning strategies for pregnant women undergoing spine surgery.

EA-DIVA score (Enhanced Adult DIVA score): A new scale to predict difficult preoperative venous cannulation in adult surgical patients.

Introduction: Providing peripheral intravenous access is one of the most commonly performed technical procedures in hospitals and it is mandatory for all patients undergoing surgery. Obtaining peripheral intravenous access may be difficult and this may cause delays in patient management, increased risk of adverse events and hospitalization costs. The aim of this study is to develop and validate a scale to identify patients at risk of peripheral difficult intravenous access, applicable to any adult patient undergoing surgery.

Expression and activation of platelet-derived growth factor β receptor, mitogen-activated protein/extracellular signal-regulated kinase kinase (MEK) and extracellular signal-regulated kinase (ERK) in canine mammary tumours.

Canine mammary tumours are frequent neoplasms mostly affecting intact female dogs, for which no 100% efficient therapy is available. Platelet derived growth factor β receptor (PDGFβR) is a tyrosine kinase receptor (TKR) with a potential role in human breast cancer and a series of canine tumours. In this study we demonstrated, for the first time, expression of PDGFβR and its downstream transduction molecules, mitogen-activated protein/extracellular signal-regulated kinase kinase (MEK) and extracellular signal-regulated kinase (ERK), as well as their activated forms in canine mammary tumours by both biochemical analysis and immunohistochemistry.
