Article Synopsis
  • - The study aimed to find opportunities for improving antibiotic stewardship (AS) in medical-surgical intensive care units (MS-ICUs) and general wards (Gral-wards) across 41 hospitals in Latin America from March 2022 to February 2023.
  • - Data was collected on antimicrobial use (AU) from 5780 MS-ICU and 7726 Gral-ward patients, revealing a 53.5% AU prevalence in MS-ICUs and 25.5% in Gral-wards, with a significant portion of antibiotics used for treating infections and surgical prophylaxis.
  • - The study highlighted key areas for improvement in AU practices, including better antibiotic selection, the need for de

NiFe₂O₄ and ZnFe₂O₄ nanoparticles have been prepared encased in the MCM (Mobile Composition of Matter) type matrix. Their magnetic behavior has been studied and compared with that corresponding to particles of the same composition and of a similar size (prepared and embedded in amorphous silica or as bare particles). This study has allowed elucidation of the role exerted by the matrix and interparticle interactions in the magnetic behavior of each ferrite system.

The ordered double perovskite Pb2NiReO6 has been prepared at 6 GPa and temperatures ranging from 1273 to 1373 K. Its crystal structure determined by X-ray powder diffraction and selected area electron diffraction shows monoclinic symmetry with centrosymmetric space group I2/m (a = 5.6021(1) Å, b = 5.
