Hemodynamic monitoring in liver transplantation 'the hemodynamic system'.

Purpose Of Review: The purpose of this article is to provide a comprehensive review of hemodynamic monitoring in liver transplantation.

Recent Findings: Radial arterial blood pressure monitoring underestimates the aortic root arterial blood pressure and causes excessive vasopressor and worse outcomes. Brachial and femoral artery monitoring is well tolerated and should be considered in critically ill patients expected to be on high dose pressors.

Intraoperative anesthetic management of the liver transplant recipient with portopulmonary hypertension.

Purpose Of Review: Liver transplantation in patients with portopulmonary hypertension (POPH) is associated with increased perioperative risk. Important recent advances in the management of liver transplantation recipients with POPH are discussed.

Recent Findings: The presence of POPH at the time of liver transplantation should not be a contraindication for liver transplantation, as POPH is common and may be related to volume overload and/or high cardiac output (CO).

PET/CT in Head-neck Malignancies: The Implications for Personalized Clinical Practice.

PET/CT has been shown to help localize head and neck cancers and provide more accurate staging, post-treatment assessment, and restaging than standard imaging. PET/CT detects synchronous and metachronous cancers and sequelae of therapy and provides prognostic information for each patient. Information provided by PET/CT allows for more individualized therapeutic and surveillance plans for patients with head and neck squamous cell carcinoma.

A corrole nanobiologic elicits tissue-activated MRI contrast enhancement and tumor-targeted toxicity.

Water-soluble corroles with inherent fluorescence can form stable self-assemblies with tumor-targeted cell penetration proteins, and have been explored as agents for optical imaging and photosensitization of tumors in pre-clinical studies. However, the limited tissue-depth of excitation wavelengths limits their clinical applicability. To examine their utility in more clinically-relevant imaging and therapeutic modalities, here we have explored the use of corroles as contrast enhancing agents for magnetic resonance imaging (MRI), and evaluated their potential for tumor-selective delivery when encapsulated by a tumor-targeted polypeptide.
