Traumatic brain injury (TBI) and long bone fractures are a common injury pattern in polytrauma patients and modulate each other's healing process. As only a limited number of studies have investigated both traumatic sites, we tested the hypothesis that brain-bone polytrauma mutually impacts neuro- and osteopathological outcomes. Adult female C57BL/6N mice were subjected to controlled cortical impact (CCI), and/or osteosynthetic stabilized femoral fracture (FF), or sham surgery.

Article Synopsis
  • Many patients with multiple sclerosis (MS) still show gradual deterioration of symptoms even when on treatment that prevents relapses, indicating the need for more comprehensive understanding beyond traditional views of MS progression.
  • The authors introduce a new term, smouldering-associated-worsening (SAW), which refers to ongoing physical and cognitive decline caused by underlying pathological processes that haven’t been adequately addressed in therapy.
  • They also suggest ways to monitor SAW using clinical, radiological, and biological markers, while emphasizing the importance of integrating findings on smouldering MS into both clinical practice and future research.

Article Synopsis
  • - Hereditary hemorrhagic telangiectasia (HHT) is a rare condition that leads to dilated blood vessels and has been linked to a higher prevalence of infections and allergies in affected individuals.
  • - In a study, 430 patients with HHT completed a survey, revealing that they experienced significantly more allergies, particularly type I allergies, along with a higher incidence of infections like sinusitis and pulmonary infections, compared to their non-affected counterparts.
  • - The findings highlight the need for increased awareness and recommendations for patients with pulmonary arteriovenous malformations (PAVMs) to take prophylactic antibiotics, as many do not do so despite their higher risk of complications.

Electronic address:

The intestinal tract generates significant reactive oxygen species (ROS), but the role of T cell antioxidant mechanisms in maintaining intestinal homeostasis is poorly understood. We used T cell-specific ablation of the catalytic subunit of glutamate cysteine ligase (Gclc), which impaired glutathione (GSH) production, crucially reducing IL-22 production by Th17 cells in the lamina propria, which is critical for gut protection. Under steady-state conditions, Gclc deficiency did not alter cytokine secretion; however, C.

Ann Neurol

October 2024

Department of Neurology and Clinical Neuroscience, Medical Center-University of Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.

Objective: To investigate whether choroid plexus volumes in subacute coronavirus disease 2019 (COVID-19) patients with neurological symptoms could indicate inflammatory activation or barrier dysfunction and assess their association with clinical data.

Methods: Choroid plexus volumes were measured in 28 subacute COVID-19 patients via cerebral magnetic resonance imaging (MRI), compared with those in infection-triggered non-COVID-19 encephalopathy patients (n = 25), asymptomatic individuals after COVID-19 (n = 21), and healthy controls (n = 21). Associations with inflammatory serum markers (peak counts of leukocytes, C-reactive protein [CRP], interleukin 6), an MRI-based marker of barrier dysfunction (CSF volume fraction [V-CSF]), and clinical parameters like olfactory performance and cognitive scores (Montreal Cognitive Assessment) were investigated.
