A murine model of acute and prolonged abdominal sepsis, supported by intensive care, reveals time-dependent metabolic alterations in the heart.

Background: Sepsis-induced cardiomyopathy (SICM) often occurs in the acute phase of sepsis and is associated with increased mortality due to cardiac dysfunction. The pathogenesis remains poorly understood, and no specific treatments are available. Although SICM is considered reversible, emerging evidence suggests potential long-term sequelae.

Patient Perceptions of Pessaries for Treatment of Pelvic Organ Prolapse.

Importance: A vaginal pessary is a highly effective treatment for patients with pelvic organ prolapse (POP). Patient views of pessaries and how their beliefs affect whether they choose pessary treatment is unknown.

Objective: Our objective of this study was to describe the knowledge, understanding, and patient concerns regarding pessary use for POP management.

Evaluation of Safety, Immunogenicity and Cross-Reactive Immunity of OVX836, a Nucleoprotein-Based Universal Influenza Vaccine, in Older Adults.

In a Phase 2a, double-blind, placebo-controlled study including healthy participants aged 18-55 years, OVX836, a nucleoprotein (NP)-based candidate vaccine, previously showed a good safety profile, a robust immune response (both humoral and cellular) and a preliminary signal of protection (VE = 84%) against PCR-confirmed symptomatic influenza after a single intramuscular dose of 180 µg, 300 µg or 480 µg. : Using the same methodology, we confirmed the good safety and strong immunogenicity of OVX836 at the same doses in older adults (≥65 years), a key target population for influenza vaccination. : Significant humoral (anti-NP IgG) and cellular (interferon gamma (IFNγ) spot-forming cells per million peripheral blood mononuclear cells and specific CD4 IFNγ T-cells) immune responses were observed at the three dose levels, without clear dose-response relationship.

Single-cell analysis of cerebrospinal fluid reveals common features of neuroinflammation.

Neuroinflammation is often characterized by immune cell infiltrates in the cerebrospinal fluid (CSF). Here, we apply single-cell RNA sequencing to explore the functional characteristics of these cells in patients with various inflammatory, infectious, and non-inflammatory neurological disorders. We show that CSF is distinct from the peripheral blood in terms of both cellular composition and gene expression.
