Switching From Pregabalin to Mirogabalin in Patients with Peripheral Neuropathic Pain: A Multi-Center, Prospective, Single-Arm, Open-Label Study (MIROP Study).

Pain Ther 2021 Apr 15. Epub 2021 Apr 15.

Department of Anesthesiology and Pain Medicine, Juntendo University Faculty of Medicine, 3-1-3 Hongo, Bunkyo-ku, Tokyo, 113-8431, Japan.

Introduction: Mirogabalin, which is a selective ligand of the αδ subunit of voltage-gated Ca channels, was recently approved in Japan for peripheral neuropathic pain. The αδ ligands, including mirogabalin and pregabalin, are associated with significant risk of adverse events (AEs) such as somnolence or dizziness, leading to poor compliance and subsequent inefficacy. Safety and efficacy data for switching patients from pregabalin to mirogabalin are scarce. Read More

Work environment and related burnout levels: survey among healthcare workers in two hospitals of Southern Italy.

Acta Biomed 2021 Mar 31;92(S2):e2021009. Epub 2021 Mar 31.

"Santa Chiara" Institute, Rome (RM), Italy .

Background And Aim Of The Work: Safety in hospitals is a structural variable on which depends not only on health, but also on physical safety of patients and employees, whom are increasingly exposed to risks as a result of which they may suffer from occupational diseases and/or develop important psycho-physical consequences.

The Neglected C of Intercultural Relations. Cross-Cultural Adaptation Shapes Sojourner Representations of Locals.

Front Psychol 2021 23;12:611630. Epub 2021 Mar 23.

VU University Amsterdam, Amsterdam, Netherlands.

We investigated, by means of the Reverse Correlation Task (RCT), visual representations of the culturally dominating group of local people held by sojourners as a function of their degree of cross-cultural adaptation. In three studies, using three different methods (reduced RCT, full RCT, conceptual replication) with three independent samples of sojourners and seven independent samples of Portuguese and US-American raters, we gathered clear evidence that poor adaptation goes along with more negative representations of locals. This indicates that sojourner adaptation is reflected, at a social-cognitive level, in the valence of outgroup representations. Read More

Fragmented sleep relates to hallucinations across perceptual modalities in the general population.

Sci Rep 2021 Apr 8;11(1):7735. Epub 2021 Apr 8.

Cognitive Neuroscience Center, Department of Biomedical Sciences of Cells and Systems, University Medical Center Groningen, University of Groningen, Internal Zipcode FA32, Antonius Deusinglaan 2, 9713 AW, Groningen, The Netherlands.

Toward more robust and reproducible diffusion kurtosis imaging.

Magn Reson Med 2021 Apr 8. Epub 2021 Apr 8.

Center for Biomedical Imaging, New York University Grossman School of Medicine, New York, NY, USA.

Purpose: The general utility of diffusion kurtosis imaging (DKI) is challenged by its poor robustness to imaging artifacts and thermal noise that often lead to implausible kurtosis values.

Theory And Methods: A robust scalar kurtosis index can be estimated from powder-averaged diffusion-weighted data. We introduce a novel DKI estimator that uses this scalar kurtosis index as a proxy for the mean kurtosis to regularize the fit. Read More

Subclinical anterior optic pathway involvement in early multiple sclerosis and clinically isolated syndromes.

Brain 2021 Apr;144(3):848-862

Experimental Neurophysiology Unit, Institute of Experimental Neurology (INSPE), San Raffaele Scientific Institute, Milan, Italy.

Optical coherence tomography (OCT) is gaining increasing relevance in the assessment of patients with multiple sclerosis. Converging evidence point to the view that neuro-retinal changes, in eyes without acute optic neuritis, reflect inflammatory and neurodegenerative processes taking place throughout the CNS. The present study aims at exploring the usefulness of OCT as a marker of inflammation and disease burden in the earliest phases of the disease. Read More

Transcortical approach and brain mapping techniques allow to identify peri-insular functional networks and, with neurophysiological monitoring, to reduce vascular-associated insults. Cognitive functions to be mapped are still under debate, and the analysis of the functional risk of surgery is currently limited to neurological examination. Read More
