Novel Indices for Lumbar Discectomy: Systemic Immune Inflammation Index, Systemic Inflammatory Response Index, Multi Inflammatory Index, and Prognostic Nutrition Index.

Aim: To evaluate systemic immune inflammation index (SII), systemic inflammatory response index (SIRI), multi-inflammatory index (MII), and prognostic nutrition index (PNI), and to compare them with the previously reported inflammation-related hematologic index in lumbar discectomy (LD).

Material And Methods: This was a retrospective, cross-sectional, single-center study with 105 consecutive patients who underwent surgery for LD. The study comprised three groups: Group I included data from healthy participants, Group II included data before LD, and Group III included data after LD.

COVID-19 Impact on Intraparenchymal Hemorrhage and Surgical Outcomes: A Comprehensive Analysis.

Aim: To investigate the possible association between COVID-19 infection and intraparenchymal hemorrhage (IPH) by examining changes in the preoperative and postoperative periods, mortality, and the impact of COVID-19 on IPH survival times.

Material And Methods: This cross-sectional retrospective analysis included 82 IPH cases operated on and treated between January 2021 and March 2023. Brain computed tomography/magnetic resonance imaging scans were used to confirm the diagnosis of IPH and provide evidence of neurological damage.
