Efficacy, Safety, and Pain Level of Subcutaneous Catheter Use for Administration of Granulocyte Colony-Stimulating Factor (G-CSF) in Children With Cancer: A Randomized Pilot Study.

The aim of this study was to explore the efficacy, safety, and pain level of granulocyte colony-stimulating factor (G-CSF) administration via a subcutaneous catheter compared with direct injection in children with cancer. This was a pilot randomized controlled trial of standard G-CSF administration versus subcutaneous catheter administration. Children 2-15 years of age who were beginning G-CSF after their first chemotherapy cycle and anticipated to receive G-CSF following the next three cycles of chemotherapy were eligible.

Edible films from residual delipidated egg yolk proteins.

Commercial extraction with organic solvents of valuable lipids from egg yolk produces a highly denatured protein waste that should be valorized. In this work, the delipidated protein waste remaining after ethanol extraction was used to prepare edible films. This material was also treated with transglutaminase, obtaining films that have also been characterized.

The Association of Poor Academic Performance with Tic Disorders: A Longitudinal, Mainstream School-Based Population Study.

Background: Little is known about the academic performance of students with tic disorders (TD). Our aim was to investigate the association of TD and poor academic performance over time.

Methods: Longitudinal, observational study of mainstream schoolchildren comparing grade retention (GR) and learning disorders (LD) in students with vs.

Photochemical synthesis of biocompatible and antibacterial silver nanoparticles embedded within polyurethane polymers.

In situ light initiated synthesis of silver nanoparticles (AgNP) was employed for AgNP incorporation within the polymeric matrices of medical grade polyurethane. The resulting materials showed improved antibacterial and antibiofilm activity against Pseudomonas aeruginosa with negligible toxicity for human primary skin cells and erythrocytes.

Prenatal and Perinatal Morbidity in Children with Tic Disorders: A Mainstream School-based Population Study in Central Spain.

Background: While current research suggests that genetic factors confer the greatest risk for the development of tic disorders, studies of environmental factors are relatively few, with a lack of consistent risk factors across studies. Our aim is to analyze the association of tic disorders with exposure to prenatal and perinatal morbidity.

Methods: This was a nested case-control study design.

Association of tic disorders with poor academic performance in central Spain: a population-based study.

Objective: To analyze the association between tic disorders and poor academic performance in school-aged children.

Study Design: This was a cross-sectional, observational study conducted in a randomly selected sample of mainstream school-aged children (aged 6-16 years). The sampling frame included different types of schools and educational levels.
