Supraspinal baclofen for the treatment of secondary generalized dystonia: A case series.

Purpose: The aim of the study was to evaluate the use of a novel technique for baclofen delivery using an intrathecal catheter inserted through a lumbar laminotomy with the tip placed at the cisterna magna (supraspinal baclofen (SSB)) for the treatment of severe generalized secondary dystonia.

Methods: A cohort study of six individuals (4M/2F, mean±SD = 15±4.86 years) with generalized dystonia unresponsive to oral medications were treated with SSB and followed clinically for 9 years.

Understanding the Correlates of Firearm Violence Involvement Among Young Adults Experiencing Homelessness: A 7-City Study.

Introduction: Young adults experiencing homelessness are vulnerable to firearm violence. This study aims to explore the correlates of firearm violence involvement among this vulnerable population, which may inform firearm violence reduction intervention development.

Methods: Between 2016 and 2017, young adults experiencing homelessness aged 18-26 years (N=1,426) were recruited in 7 U.

Universal signatures of Majorana-like quasiparticles in strongly correlated Landau-Fermi liquids.

Motivated by recent experiments in the Kitaev honeycomb lattice, Kondo insulators, and the 'Luttinger's theorem-violating' Fermi liquid phase of the underdoped cuprates, we extend the theoretical machinery of Landau-Fermi liquid theory to a system of itinerant, interacting Majorana-like particles. Building upon a previously introduced model of 'nearly self-conjugate' fermionic polarons, a Landau-Majorana kinetic equation is introduced to describe the collective modes and Fermi surface instabilities in a fluid of particles whose fermionic degrees of freedom obey the Majorana reality condition. At large screening, we show that the Landau-Majorana liquid harbors a Lifshitz transition for specific values of the driving frequency.

Unconventional Hund metal in a weak itinerant ferromagnet.

The physics of weak itinerant ferromagnets is challenging due to their small magnetic moments and the ambiguous role of local interactions governing their electronic properties, many of which violate Fermi-liquid theory. While magnetic fluctuations play an important role in the materials' unusual electronic states, the nature of these fluctuations and the paradigms through which they arise remain debated. Here we use inelastic neutron scattering to study magnetic fluctuations in the canonical weak itinerant ferromagnet MnSi.
