Core and surface structure and magnetic properties of mechano-synthesized LaFeO nanoparticles and their Eu-doped and Eu/Cr-co-doped variants.

The core and surface structure, and magnetism of mechano-synthesized LaFeO nanoparticles (30-40 nm), Eu-doped (LaEuFeO), and Eu/Cr co-doped (LaEuFeCrO) are reported. Doping results in a transition from the O'-type to the O-type distorted structure. Traces of reactants, intermediate phases, and a small amount of Eu ions were detected on the surfaces of the nanoparticles.

Perceived Knowledge, Attitude, and Practices (KAP) and Fear toward COVID-19 among Patients with Diabetes Attending Primary Healthcare Centers in Kuwait.

Objectives: To assess perceived fear and to evaluate the level of knowledge, attitude, and prevention practices (KAP) regarding COVID-19 infection among patients with diabetes mellitus (DM) attending primary healthcare centers (PHCs) in Kuwait. This will help evaluate gaps and provide appropriate support to limit the spread of COVID-19 infection in high-risk patients.

Methods: A descriptive cross-sectional study was carried out using a self-administered questionnaire.

Minimally invasive retrieval of a bullet settling into the thoracic spinal canal in a pediatric patient: A case report.

A 10-year-old boy presented to neurosurgery department after a gunshot wound to the upper thoracic spine. The bullet entered through the right deltoid muscle and lodged inside the spinal canal at T1 level. The patient arrived conscious and obeying commands; however, he experienced a loss of sensation below T3 level, loss of reflexes below the injured T1 level, loss of anal sphincter tone and paraplegia in the lower limbs (American Spinal Injury Association grade-A).
