Haemodialysis improves uraemic patients' cognition : a pilot study

Uraemia is a state of elevated plasma urea well related to a low cognitive profile. Although renal transplantation has been proved to improve cognition in these patients, little is known about how haemodialysis act on this scenario. Here we aimed to conduct a pilot study to fathom the presence and magnitude of a possible benefit of haemodialysis in cognition. Our main instrument was the Montreal Cognitive Assessment (MoCA) test, a tool designed to allow for a sensitive score for cognitive impairment. Although preliminary, our data were significant (p=0.012) to suggest that haemodialysis might be an important tool for cognitive improvement of end-stage kidney disease patients, tough not sufficient for a full cognitive recovery

Attention-deficit/hyperactivity disorder and brain metabolites from proton magnetic resonance spectroscopy : a systematic review and meta-analysis protocol

Despite major advances in the study of the brain, investigations on neurochemistry in vivo still lack the solid ground of more established methods, such as structural and functional magnetic resonance imaging. Proton magnetic resonance spectroscopy (MRS) is a technique that might potentially fill in this gap. Nevertheless, studies using this approach feature great methodological heterogeneity, such as varying voxel of choice, differences on emphasized metabolites, and absence of a standardized unit. In this study, we present a methodology for creating a systematic review and meta-analysis for this kind of scientific evidence using the prototypical case of attention-deficit/hyperactivity disorder
