Serum interleukin-6, procalcitonin, and C-reactive protein at hospital admission can identify patients at low risk for severe COVID-19 progression.

Background: COVID-19 can show a variable course, from asymptomatic infections to acute respiratory failure and death. For efficient allocation of resources, patients should be stratified according to their risk for a severe course as early as possible.

Methods: 135 hospitalized patients with COVID-19 pneumonia at four German hospitals were prospectively included in this observational study.

Relaxation-weighted Na magnetic resonance imaging maps regional patterns of abnormal sodium concentrations in amyotrophic lateral sclerosis.

Objectives: Multiparametric magnetic resonance imaging (MRI) is established as a technical instrument for the characterisation of patients with amyotrophic lateral sclerosis (ALS). The contribution of relaxation-weighted sodium (NaR) MRI remains to be defined. The aim of this study is to apply NaR MRI to investigate brain sodium homeostasis and map potential alterations in patients with ALS as compared with healthy controls.
