Diagnostic accuracy of MRI without gadolinium for follow-up of pilocytic astrocytoma in the paediatric population.

Purpose: Pilocytic astrocytoma is the most common glial tumour in the paediatric population with a long-term life expectancy after surgery. Long-term radiological follow-up with magnetic resonance imaging (MRI) is necessary to detect recurrence of tumour or growth of residual tumour. Established MRI protocols typically dictate post-gadolinium sequences despite concerns around the side-effect and safety concerns of gadolinium-based contrast agents.

Effect of using home-based dynamic intermittent pneumatic compression therapy during periods of physical activity on functional and vascular health outcomes in chronic stroke: A randomized controlled clinical trial.

Background: Intermittent pneumatic compression (IPC) therapy may benefit stroke patients by eliciting more intensive training sessions that may result in better health, mobility and ultimately quality of life. The purpose of this randomized controlled trial was to assess the effect of using a home-based IPC device on functional outcomes and vascular health in individuals with chronic stroke.

Methods: Thirty-one stroke survivors (64.

Jekyll and Hyde leadership: Examining the direct and vicarious experiences of abusive and ethical leadership through a justice variability lens.

Drawing on uncertainty management theory and the nascent work on justice variability, we examine employees' and experiences of abusive supervision and ethical leadership. Conceptualizing the simultaneous display of abusive and ethical leadership styles as a form of justice variability, we suggest that a direct supervisor's ethical leadership exacerbates, rather than ameliorates, the detrimental effects of his/her abusive supervision on employees' emotional exhaustion and job performance. We further contend that a similar effect exists when employees vicariously experience leadership interactions involving their direct supervisor and higher level manager, whereby higher level managers' ethical leadership exacerbates the negative effects of their abusive supervision toward supervisors on those supervisors' employees' emotional exhaustion and job performance.

Genotype MTBDRsl version 2 and phenotypic drug resistance detection of for fluoroquinolones and aminoglycosides.

Background: Information on genotypic with comparison of phenotypic drug sensitivity test of anti-tuberculosis (TB) has been reported in several studies, which have variable results. The present study aimed to assess the Genotype MTBDRsl version 2.0/Line probe assay (LPA) for the detection of fluoroquinolones (FQ) and aminoglycosides (AMGs) resistance mutations among drug-resistant Mycobacterium TB (MTB) strains and also to compare the patterns of genotypic mutations of gyrA/B, rrs, and eis with mycobacteria growth indicator tube (MGIT 960).
