Genomic landscape of high-grade meningiomas.

High-grade meningiomas frequently recur and are associated with high rates of morbidity and mortality. To determine the factors that promote the development and evolution of these tumors, we analyzed the genomes of 134 high-grade meningiomas and compared this information with data from 587 previously published meningiomas. High-grade meningiomas had a higher mutation burden than low-grade meningiomas but did not harbor any statistically significant mutated genes aside from .

Elevated Hemoglobin A1c Is Associated With Lower Socioeconomic Position and Increased Postoperative Infections and Longer Hospital Stay After Cardiac Surgical Procedures.

Background: Patients with elevated hemoglobin A1c (HbA1c) levels have an increased risk of adverse short- and long-term outcomes after cardiac surgical procedures. Whether elevated HbA1c levels are associated with lower socioeconomic position (SEP) has been unknown.

Methods: All adult patients undergoing cardiac surgical procedures at Kansas University Medical Center in Kansas City, Kansas in 2014 (n = 567) were reviewed.

Prevalence of problematic mobile phone use in British adolescents.

The problematic use of mobile phones among adolescents has not been widely studied. There are very few instruments for assessing potential technological addiction to mobile phones, or for categorizing different types of users or uses. The most widely used scale is the Mobile Phone Problem Use Scale (MPPUS), which is used to study adult populations, and has been applied in various forms in international contexts.

Online vs. face-to-face discussion in a Web-based research methods course for postgraduate nursing students: a quasi-experimental study.

Background: Web-based technologies are increasingly being used to create modes of online learning for nurses but their effect has not been assessed in nurse education.

Objectives: Assess whether participation in face-to-face discussion seminars or online asynchronous discussion groups had different effects on educational attainment in a web-based course.

Design: Non-randomised or quasi-experimental design with two groups-students choosing to have face-to-face discussion seminars and students choosing to have online discussions.
