AI Article Synopsis

  • Encephalitis symptoms usually include seizures, memory issues, and altered consciousness, with initial cases sometimes involving psychosis, prompting questions about the relationship between first-episode psychosis (FEP) and encephalitis.
  • Researchers studied 36 encephalitis patients with FEP, evaluating outcomes based on various factors, with a focus on the modified Rankin scale for measuring functional outcomes.
  • Findings revealed that female sex and the need for mechanical ventilation during early treatment are significant indicators of worse outcomes, particularly highlighting mechanical ventilation as a strong prognostic factor for adverse developments in patients with encephalitis and FEP.

Article Abstract

Introduction: Although symptomatic manifestations in encephalitis vary, they typically include seizures, memory deficit(s), and altered consciousness. Psychosis also occurs as an initial manifestation. In clinical practice, clinicians often encounter the question of whether first-episode psychosis (FEP) originates from encephalitis itself or if encephalitis presenting with FEP develops concurrently. The prognosis of FEP among patients with overall encephalitis, including autoimmune encephalitis, remains uncertain.

Methods: We examined a prognostic factor in patients with encephalitis who had both FEP and CSF pleocytosis. A total of 36 patients who presented with FEP were enrolled. A score of ≥3 and ≤2 on the modified Rankin scale were defined as poor and good outcomes, respectively. A total of 13 independent variables were analyzed by the multivariate logistic regression analysis.

Results: Significant variables on univariate logistic regression analysis included female sex (OR 5.571, 95% CI: 1.297-23.934; p = 0.021) and the use of mechanical ventilation during the acute stage (OR 7.286, 95% CI: 1.508-35.211; p = 0.013). On multivariate logistic regression analysis, the use of mechanical ventilation during the acute stage (OR 5.446, 95% CI: 1.044-28.615; p = 0.044) was significantly associated with poor outcomes.

Conclusions: The use of mechanical ventilation is a poor prognostic factor of subacute encephalitis with FEP, and female sex may be a risk factor for unfavorable development of the disease.

Identifying inflammation-induced leukocyte subsets and their derived circulating factors has been instrumental in understanding the progession of ALI/ARDS. Nevertheless, how primary inflammation-induced non-leukocyte populations in distal organs contribute to ALI/ARDS remains poorly defined. Here, we report one population of erythroblast-like cells (Ter-cells) deriving from megakaryocyte- erythroid progenitor cells with a unique Ter-119+CD45-CD71+ phenotype in ALI/ARDS.

Microfilaria in the Urine of a Dog with Concurrent Urinary Bladder Sarcoma.

J Am Anim Hosp Assoc

January 2025

From the Department of Veterinary Clinical Services, College of Veterinary Medicine, University of Minnesota, St. Paul, Minnesota (N.S., A.H., D.H.).

A 12 yr old female spayed American Staffordshire terrier was referred for stranguria, pollakiuria, and concern for a mass in the trigone of the urinary bladder. A urinalysis and abdominal ultrasound were performed to further investigate the bladder mass. Nematode larvae were identified in the urine, termed microfilaruria, while a caudal abdominal mass was found on ultrasound impinging on the urethra.

MYCN-amplified spinal ependymomas: a rare aggressive subtype. Illustrative cases.

J Neurosurg Case Lessons

January 2025

Department of Radiology and Biomedical Imaging, University of California, San Francisco, California.

Background: Spinal ependymomas are typically slow-growing tumors with a favorable prognosis. Recently, a new aggressive subtype has emerged with its own distinct histopathological and molecular features characterized by MYCN amplification. However, this subtype of spinal ependymoma is rare, and studies on its imaging characteristics are limited.

Purpose: To report one-year real-world evidence on intraocular inflammation (IOI) adverse events (AEs) in patients undergoing faricimab therapy in a tertiary care hospital.

Methods: A retrospective review of electronic medical records was conducted for patients receiving faricimab treatment for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME) at Moorfields Eye Hospital between September 1st, 2022, and August 31st, 2023. The primary outcome was the incidence of IOI (excluding endophthalmitis).
