3D modeling to predict vascular involvement in resectable pancreatic adenocarcinoma.

Background: Current management of patients with borderline resectable pancreatic adenocarcinoma (BR-PDAC) depends on the degree of involvement of the major arterial and venous structures. The aim of this study was to evaluate 3D segmentation and printing to predict tumor size and vascular involvement of BR-PDAC to improve pre-operative planning of vascular resection and better select patients for neoadjuvant therapy.

Methods: We retrospectively evaluated 16 patients with BR-PDAC near vascular structures who underwent pancreatoduodenectomy (PD) with or without vascular resection between 2015 and 2021.

New Saccharomyces cerevisiae-Kluyveromyces marxianus fusant shows enhanced alcoholic fermentation performance.

Kluyveromyces marxianus has a promising enological potential because of strong extracellular pectinase activity and the copious production of specific higher alcohols and esters. However, K. marxianus is unable to complete alcoholic fermentation on its own.

Meta-analysis on pharmacological therapies in the management of xerostomia in patients with Sjogren's syndrome.

Sjogren's syndrome is an immunologic disorder, characterized by symptoms of dry mouth and dry eyes. Management of xerostomia is more difficult and challenging, various pharmacologic agents have been tried and evaluated in the management of xerostomia in these patients, but the results were inconsistent and variable. Hence, the present study is aimed at evaluation and comparison of different pharmacological agents in the management of xerostomia in patients with Sjogren's syndrome.

Assessment and comparison of target registration accuracy in surgical instrument tracking technologies.

Image guided surgery systems aim to support surgeons by providing reliable pre-operative and intra-operative imaging of the patient combined with the corresponding tracked instrument location. The image guidance is based on a combination of medical images, such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) and Ultrasonography (US), and surgical instrument tracking. For this reason, tracking systems are of great importance as they determine location and orientation of the equipment used by surgeons.
