Comparison of positive BioFire FilmArray meningitis/encephalitis (ME) panels, CSF cultures, CSF parameters, clinical presentation and in-patient mortality among patients with bacterial and fungal meningitis.

Unlabelled: The BioFire FilmArray meningitis/encephalitis panel (MEP) was brought to the University of Kentucky in 2016 to aid in the identification of community-acquired meningitis and encephalitis (ME). This panel has shown variable performance with some institutions showing high sensitivity and specificity for many pathogens but others seeing false positives during clinical use. We evaluated the panel's performance using retrospective chart review of patients at the University of Kentucky from October 2016 to September 2022, including 7,551 MEP results.

Increased Platelet Adhesiveness in Patients with Venous Thromboembolic Disease.

 Association between global platelet function and the risk of venous thromboembolic disease (VTE) has been proposed, though the mechanisms do not involve increased platelet aggregation. However, platelet adhesiveness has not been systematically explored in VTE patients.  To evaluate platelet adhesive functions in VTE patients.

Liquid Biopsy versus CT: Comparison of Tumor Burden Quantification in 1065 Patients with Metastases.

Background Tumor fraction (TF) at liquid biopsy is a potential noninvasive marker for tumor burden, but validation is needed. Purpose To evaluate TF as a potential surrogate for tumor burden, assessed at contrast-enhanced CT across diverse metastatic cancers. Methods This retrospective monocentric study included patients with cancer and metastatic disease, with TF results and contemporaneous contrast-enhanced CT performed between January 2021 and January 2023.

Protein tau phosphorylation in the proline rich region and its implication in the progression of Alzheimer's disease.

Tau has a wide variety of essential functions in the brain, but this protein also plays a determining role in the development of Alzheimer's disease (AD) and other neurodegenerative diseases called tauopathies. This is due to its abnormal aggregation and the subsequent formation of neurofibrillary tangles. Tau hyperphosphorylation appears to be a critical step in its transformation into an aggregated protein.
