Two hundred patients with liver disease were re-studied after six to eight years. The initial routine diagnosis (mainly based on morphological criteria) was confirmed in almost 80% of cases of chronic liver disease. In chronic active hepatitis, agreement was found in 86%. An alternative classification based on cluster analysis of clinical chemical results from the first admission was also to a great extent confirmed by the follow-up study. Discriminant analysis of clinical chemical data correctly allocated 94% of patients with alcoholic cirrhosis (who had low haptoglobin and albumin) into groups with different prognosis. Clinical chemical results differed between verified and non-verified cases of primary biliary cirrhosis. By retrospective examination , we found that 15 of 16 patients with this disease or chronic active hepatitis who were initially misclassified by biopsy findings could be correctly diagnosed by discriminant analysis of clinical chemical results.

Ageing and inflammation limit the induction of SARS-CoV-2-specific CD8+ T cell responses in severe COVID-19.
JCI Insight

CD8+ T cells are critical for immune protection against severe COVID-19 during acute infection with SARS-CoV-2. However, the induction of antiviral CD8+ T cell responses varies substantially among infected people, and a better understanding of the mechanisms that underlie such immune heterogeneity is required for pandemic preparedness and risk stratification. In this study, we analyzed SARS-CoV-2-specific CD4+ and CD8+ T cell responses in relation to age, clinical status, and inflammation among patients infected primarily during the initial wave of the pandemic in France or Japan.

Antibacterials with Novel Chemical Scaffolds in Clinical Development.
Drugs

Department of Chemical Biology, Helmholtz Centre for Infection Research, Inhoffenstraße 7, 38124, Braunschweig, Germany.
The rise of antimicrobial resistance represents a significant global health threat, driven by the diminishing efficacy of existing antibiotics, a lack of novel antibacterials entering the market, and an over- or misuse of existing antibiotics, which accelerates the evolution of resistant bacterial strains. This review focuses on innovative therapies by highlighting 19 novel antibacterials in clinical development as of June 2024. These selected compounds are characterized by new chemical scaffolds, novel molecular targets, and/or unique mechanisms of action, which render their potential to break antimicrobial resistance particularly high.

Purpose: Chemical chelation with ethylenediaminetetraacetic acid (EDTA) is an established treatment for calcific band keratopathy (CBK), whereas removal of calcium deposits from the subepithelial layer of the cornea may cause corneal irregularity. Using Fourier harmonic analysis, we analyzed the corneal topography in eyes with CBK treated by EDTA chelation.

Manganese exposure induces parkinsonism-like symptoms by Serpina3n-TFEB-v/p-ATPase signaling mediated lysosomal dysfunction.

Manganese (Mn) is a neurotoxin that has been etiologically linked to the development of neurodegenerative diseases in the case of overexposure. It is widely accepted that overexposure to Mn leads to manganism, which has clinical symptoms similar to Parkinson's disease (PD), and is referred to as parkinsonism. Astrocytes have been reported to scavenge and degrade extracellular α-synuclein (α-Syn) in the brain.
