Background: Spinal cord (SC) atrophy is a key imaging biomarker of progressive multiple sclerosis (MS). Progressive MS is more common in men and postmenopausal women.

Objective: Investigate the impact of sex and menopause on SC measurements in persons with MS (pwMS).

Aim/hypothesis: The main aim of the study was to identify point of care available laboratory and clinical predictors of 7‑day mortality in critically ill patients with a hyperglycemic crisis.

Methods: A retrospective study of 990 patients with the first hospitalization due to hyperglycemia was performed. Patients were classified as having diabetic ketoacidosis (DKA) or being in a hyperosmolar hyperglycemic state (HHS) according to the recommendations of the American Diabetes Association (ADA).

Importance: Although 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a well-established cross-sectional biomarker of brain metabolism in dementia with Lewy bodies (DLB), the longitudinal change in FDG-PET has not been characterized.

Objective: To investigate longitudinal FDG-PET in prodromal DLB and DLB, including a subsample with autopsy data, and report estimated sample sizes for a hypothetical clinical trial in DLB.

Design, Setting, And Participants: Longitudinal case-control study with mean (SD) follow-up of 3.

Article Synopsis
  • MR fingerprinting (MRF) is an innovative technique for measuring MR relaxometry with high precision, but its complex data requirements hinder its widespread use.
  • A deep learning (DL) network, specifically a U-Net, was created to synthesize MRF signals from regular magnitude-only MRI data collected from 37 volunteers, comparing the results with actual acquired MRF signals.
  • The study found strong concordance between synthesized and actual MRF data, indicating that DL can enable quantitative relaxometry without the need for specialized MRF pulse sequences.

Antimicrobial susceptibility testing (AST) in the veterinary sector by broth microdilution is mainly based on commercially available microtitre plates with specific panels. A critical review of commercially available microtitre panels identified AST panels that fulfil the requirements for obtaining reliable AST results by covering the necessary antimicrobial concentrations for both clinical breakpoints as well as quality control (QC) ranges for approved QC strains. However, there are AST panels in which these prerequisites are only in part fulfilled, and some AST panels that do not fulfil the aforementioned criteria at all.
