The objective of this pilot study was to assess the reliability of superb microvascular ultrasound (SMI) for the measurement of the cerebrospinal fluid (CSF) flow within VPS systems as an indirect sign for shunt dysfunction. Asymptomatic hydrocephalus patients, with a VPS system implanted between 2017 and 2021, were prospectively enrolled in the study. Using SMI, the CSF flow within the proximal and distal catheters were analysed.

The aim of this study was to evaluate the incidence of, and risk factors for, acute kidney injury and its effect on clinical outcomes of critically ill COVID-19 patients in Tyrol, Austria.
Methods: This multicenter prospective registry study included adult patients with a SARS-CoV-2 infection confirmed by polymerase chain reaction, who were treated in one of the 12 dedicated intensive care units during the COVID-19 pandemic from February 2020 until May 2022.
Objective: Increased intracranial pressure (ICP) is most likely not being transmitted uniformly within the cranium. The ICP profiles in the supra- and infratentorial compartments remain largely unclear. Increased ICP in the cerebellum, however, is insufficiently captured by supratentorial ICP (ICPsup) monitoring due to compartmentalization through the tentorium.

- The study analyzed critically ill COVID-19 patients in Tyrol, Austria, comparing two periods of the pandemic to identify changes in patient characteristics and treatment methods.
- During the second wave, patients were older, and treatments like mechanical ventilation and vasopressors were used less frequently, leading to shorter ICU stays.
- However, while ICU mortality rates remained stable, hospital mortality rates increased, indicating the need for further investigation into factors such as age and comorbidities that may predict outcomes.
Background: Cerebrospinal fluid (CFS) leaks are a well-known complication in spinal surgery, caused mostly by incidental durotomy (ID). Management of ID is a matter of ongoing debate. Different treatment strategies have been described ranging from no specific treatment to intraoperative suture or even complex reconstructive procedures.

- The first COVID-19 cases in Tyrol, Austria were detected on February 25, 2020, leading to swift preparations for ICU patient care amid the pandemic.
- A study tracked 106 critically ill COVID-19 patients admitted to ICUs in Tyrol between March 9 and July 17, 2020, highlighting key demographics and treatment needs like mechanical ventilation and renal support.
- ICU and hospital mortality rates were approximately 21.7% and 22.6%, respectively, with findings suggesting a high severity of illness but a relatively low overall mortality rate in the ICU setting.
