Safety of Triple-Dose Rifampin in Tuberculosis Treatment: A Systematic Review and Meta-Analysis.

Background: There is growing interest in using high-dose rifampin for tuberculosis treatment. Recent studies suggest that triple-dose rifampin (TDR; ≥30 mg/kg/day) may be unsafe. We updated a systematic review to investigate the safety and efficacy of TDR.

Utility of T2-weighted MRI and contrast-enhanced MRA in locating the fistula level of spinal arteriovenous fistula.

Objective: To investigate the value of routine T2-weighted magnetic resonance imaging (MRI) and contrast-enhanced magnetic resonance angiography (CE-MRA) sequences in locating the fistula level of spinal arteriovenous fistula (SAVF).

Methods: Retrospectively analyzed the radiological findings of patients with SAVF diagnosed by surgery from May 2018 to September 2024. All patients completed spinal CE-MRA and routine T2-weighted MRI.
