Trekking Poles to Aid Multiple Sclerosis Walking Impairment: An Exploratory Comparison of the Effects of Assistive Devices on Psychosocial Impact and Walking.

Background: Walking dysfunction is reported by two-thirds of persons with multiple sclerosis (MS). Assistive devices are frequently recommended to improve walking; however, it is uncommon to consider their psychosocial impact, although many users abandon their assistive devices. The psychosocial impact, walking, balance, and fatigue associated with three assistive devices were compared to guide clinical decision making.

Efficacy of Vortioxetine Monotherapy for Posttraumatic Stress Disorder: A Randomized, Placebo-Controlled Trial.

Purpose/background: There are few efficacious pharmacological treatments for posttraumatic stress disorder (PTSD) and many patients fail to benefit from existing treatments. Vortioxetine, a recently developed antidepressant, acts as a serotonin modulator through inhibition of the serotonin transporter and actions at multiple types of serotonin receptors. Its unique pharmacodynamic profile suggests it may have efficacy for the treatment of PTSD.

Lifetime employment in schizophrenia: correlates of developing long term unemployment after being employed before.

Background: Challenges in employment are highly prevalent among people with schizophrenia regardless of their employment history. Although supportive employment can be effective, few participants sustain meaningful competitive employment. Our goal was to identify the correlates of developing sustained unemployment.

The evolutionary origins and diversity of the neuromuscular system of paired appendages in batoids.

Appendage patterning and evolution have been active areas of inquiry for the past two centuries. While most work has centred on the skeleton, particularly that of amniotes, the evolutionary origins and molecular underpinnings of the neuromuscular diversity of fish appendages have remained enigmatic. The fundamental pattern of segmentation in amniotes, for example, is that all muscle precursors and spinal nerves enter either the paired appendages or body wall at the same spinal level.

Macrophage-derived netrin-1 promotes abdominal aortic aneurysm formation by activating MMP3 in vascular smooth muscle cells.

Abdominal aortic aneurysms (AAA) are characterized by extensive extracellular matrix (ECM) fragmentation and inflammation. However, the mechanisms by which these events are coupled thereby fueling focal vascular damage are undefined. Here we report through single-cell RNA-sequencing of diseased aorta that the neuronal guidance cue netrin-1 can act at the interface of macrophage-driven injury and ECM degradation.
