COVID-19 Pandemic Changes Epidemiology, Clinical Features and Laboratory Markers of Epstein-Barr Virus Infection in Children: A Three-Period Retrospective Study of 438 Cases

This retrospective study of 438 hospitalized Chinese children reveals that the COVID-19 pandemic significantly altered the epidemiology, clinical severity, and laboratory profiles of Epstein-Barr virus infections, shifting the pattern from primary infections during strict containment to increased viral reactivation and severe complications in the post-pandemic period.

Beyond Ventilation: The Non-linear Impact of Per Capita Spatial Volume on Nosocomial Respiratory Virus Transmission in Hospital Wards — A Real-World Natural Experiment

This real-world natural experiment demonstrates that, even with identical mechanical ventilation systems, a 52% reduction in per capita spatial volume in hospital wards is associated with a six-fold increase in nosocomial SARS-CoV-2 transmission, establishing per capita volume as a critical, non-linear determinant of infection risk that warrants equal consideration with air exchange rates in hospital design standards.

AI Benefits and Machine Learning Errors - Neurology, Psychiatry and Neurosurgery

This systematic review of 79 studies (2018–2026) highlights that while AI significantly enhances neurology, psychiatry, and neurosurgery through improved diagnostics and surgical precision, it also introduces substantial risks of misdiagnosis and bias—particularly in underrepresented populations and edge cases—necessitating strict error tracking, fairness audits, and human oversight to ensure safe clinical implementation.

Phytochemical-Based Protection Against Benzene-Triggered Leukemic Injury Through Hematologic Recovery, Tissue Preservation, and Nrf2/Caspase-3 Modulation in Rats

This study demonstrates that treatment with *Withania somnifera*, either alone or in combination with green tea extract and curcumin, effectively mitigates benzene-induced leukemic injury in rats by restoring hematological parameters, preserving tissue architecture, and modulating Nrf2 and Caspase-3 expression, with the combination therapy showing superior efficacy in addressing oxidative stress and apoptosis.

Post-Landing Orthostatic Intolerance after Spaceflight: Characterization of Intravenous Fluid Resuscitation in NASA Astronauts

A retrospective review of 79 NASA astronauts reveals that post-landing orthostatic intolerance is frequently treated with highly variable, non-standardized intravenous fluid volumes lacking evidence-based guidelines, highlighting an urgent need for physiology-informed protocols for future deep-space missions.

The Quantified Epidemic Energy (QEE) Model: A Stochastic Framework for Climate- Sensitive Cholera Forecasting in Yemen

This study introduces the Quantified Epidemic Energy (QEE) model, a novel stochastic framework that integrates climate risk and reporting delays to accurately forecast cholera incidence in Yemen's Al-Hodeidah Governorate, offering a robust, uncertainty-quantified tool for proactive early-warning systems in data-scarce, conflict-affected settings.

Predictors of Malignancy in Isolated Mammographic Microcalcifications: A Retrospective Cohort Study of Patients Undergoing Stereotactic Biopsy

This retrospective cohort study of 173 patients undergoing stereotactic biopsy for suspicious mammographic microcalcifications found that malignancy was present in 21.4% of cases and identified regional and linear distribution patterns, along with pleomorphic morphology, as independent predictors of malignancy.
