Purpose: This study investigates the relationship between surgical levels and coronal deformity to identify risk factors for failing to achieve a minimal clinically important difference (MCID) in the Oswestry Disability Index (ODI) following short-segment isolated decompression or fusion surgery in patients with degenerative scoliosis (DS) and concurrent lumbar canal stenosis (LCS), without severe sagittal deformity malalignment.
Methods: Patients with degenerative scoliosis who underwent 1- or 2-level lumbar isolated decompression or fusion surgery were included. Surgical level was labeled as "Cobb-related" when decompression or surgical levels spanned or were between end vertebrae, and "outside" when the operative levels did not include the end vertebrae.
Study Design: Retrospective cohort study.
Summary Of Background Data: The optimal surgical approach for multilevel cervical stenosis in elderly patients is controversial because of the risk of life-threatening complication.
Objective: To compare life-threatening early complication rates between ≥3 levels anterior and posterior cervical surgery in elderly patients.
Potassium-sulfur batteries (KSBs) have garnered immense attention as a high-energy, cost-effective energy storage system. Nevertheless, achieving optimal sulfur utilization and long-term cycling is the primary challenge. To address some of the different challenges of KSBs, a potassium-sulfur (K/S) battery cathode was fabricated using MoS, SiC, and S (Mo@Si@S) in a fixed ratio.

However, the sluggish conversion reaction kinetics and the shuttle effect of magnesium polysulfides hinder their practical application. The high charge density of the divalent Mg cations leads to slow kinetics caused by significant electrostatic interactions between Mg and its surrounding solvent and anion species.
