Sepsis subtypes and differential treatment response to vitamin C: biological sub-study of the LOVIT trial.

Intensive Care Med

January 2025

Centre for Inflammation Research, Institute For Regeneration and Repair, University of Edinburgh, Edinburgh, Scotland, UK.

Purpose: We hypothesised that the biological heterogeneity of sepsis may highlight sepsis subtypes with differences in response to intravenous vitamin C treatment in the Lessening Organ Dysfunction with VITamin C (LOVIT) trial. Our aims were to identify sepsis subtypes and to test whether sepsis subtypes have differences in treatment effect to vitamin C and describe putative biological effects of vitamin C treatment.

Methods: We measured biomarkers of inflammation, at baseline and at 7 days post-randomisation, in 457/863 (53.

Purpose: Primary bilateral macronodular adrenal hyperplasia (PBMAH), the most common cause of Cushing's syndrome due to bilateral nodules, is a heterogeneous disease at the clinical, hormonal and morphological levels. ARMC5 inactivating pathogenic variants are causative of PBMAH and rare variants of PDE11A have been associated with PBMAH.

Methods: Leukocyte DNA of 354 PBMAH index cases was sequenced for ARMC5 and PDE11A genes by Next generation sequencing (NGS).

Chronic stress can result in various conditions, including psychological disorders, neurodegenerative diseases, and accelerated brain aging. Gut dysbiosis potentially contributes to stress-related brain disorders in individuals with chronic stress. However, the causal relationship and key factors between gut dysbiosis and brain disorders in chronic stress remain elusive, particularly under non-sterile conditions.

This was an original article, and the objective of this study was to investigate the effects of bipolar transurethral plasma kinetic prostatectomy (TUPKP) on urodynamics and sexual function in benign prostatic hyperplasia (BPH) patients. One hundred and four BPH patients were divided into a control group and an intervention group. The control group received transurethral resection of prostate, while the intervention group received TUKEP.

Can Aluminum Affect Social Behavior and Cortisol Plasma Profile in the Neotropical Freshwater Teleost (Teleostei: Characidae)?

Life (Basel)

December 2024

Laboratório de Aquicultura e Ecofisiologia Marinha (LAQUEFIM), Departamento de Fisiologia, Instituto de Biociências, Universidade de São Paulo (IB/USP), Rua do Matão, trav. 14, No. 321, Cidade Universitária, São Paulo 05508-090, SP, Brazil.

Aluminum (Al) can cause endocrine disruption in aquatic animals, but assessments of animal social behavior in neotropical teleost fish species with importance for Brazilian aquaculture have still not been addressed so far, which can further complete this ecotoxicological knowledge. In order to evaluate the social behavior and plasma cortisol concentration of fish exposed to Al, we performed a 1 h acute exposure with couples in three different experimental groups: control in neutral pH (CTL/n group), acid pH (pH/ac group), and aluminum in acid pH (Al/ac group; 2.0 mg L).
