Neurological complications in patients undergoing veno-venous extracorporeal membrane oxygenation (V-V ECMO) are challenging, with new intracranial pathologies posing a grave risk. We aimed to evaluate the utility of neuron-specific enolase (NSE) and S100B biomarkers for predicting outcomes in new-onset intracranial pathology during V-V ECMO. A retrospective analysis spanning 2013-2021 at a German university hospital was conducted.

Purpose: Prophylactic insertion of an external ventricular drainage (EVD) prior to the resection of posterior fossa metastases (PFMs) is a common approach to address postoperative transient and permanent hydrocephalus. However, predicting surgery-related hydrocephalus in the preoperative phase continues to be a challenge. This study aims to analyze the incidence, preoperatively collectable risk factors and necessity of perioperative external ventricular drainage placement after posterior fossa metastasis surgery.

Approximately 10-20% of subjects vaccinated with HBsAg-based hepatitis B virus (HBV) vaccines are non-responders. BM32 is a recombinant grass pollen allergy vaccine containing the HBV-derived preS surface antigen as an immunological carrier protein. PreS includes the binding site of HBV to its receptor on hepatocytes.

Purpose: The purpose of this study was to evaluate the temperature generated on the intaglio surface and efficiency when cutting different types of zirconia with different rotary instruments and rotational speeds.

Methods: A conventional diamond rotary instrument (Brasseler, grit size 107 μm) and special diamond rotary instrument marketed to cut zirconia (4 ZR, Brasseler, grit size 126 μm) were tested on 3Y-TZP and 4Y-TZP zirconia with a rotation speed of 100,000 rpm and 200,000 rpm. Zirconia specimens were cut under water cooling (110 mL/min) in a custom-made holder attached to a universal testing machine.

Patients with polytrauma and other severe musculoskeletal injuries often suffer from permanently impaired functionality and quality of life. This results in long-term damage with high costs for the social system. A narrative review will show the impact of targeted coordination in the rehabilitation process from early rehabilitation to long-term case management on patients with severe musculoskeletal injuries.
