Does age, sex, and area of substantia nigra echogenicity predict the MRI appearance of nigrosome-1?

The appearance of the substantia nigra (SN) can aid diagnosis of Parkinson's disease (PD). The effect of age and sex on the appearance of nigrosome-1 (SN subregion) on magnetic resonance imaging (MRI), and the relationship between nigrosome-1 (viewed with MRI) and SN echogenicity (viewed with transcranial ultrasound) is unknown. The study aimed to address these knowledge gaps.

Prevention of Stroke in Intracerebral Haemorrhage Survivors with Atrial Fibrillation: Rationale and Design for PRESTIGE-AF Trial.

Adequate secondary prevention in survivors of intracerebral hemorrhage (ICH) who also have atrial fibrillation (AF) is a long-standing clinical dilemma because these patients are at increased risk of recurrent ICH as well as of ischemic stroke. The efficacy and safety of oral anticoagulation, the standard preventive medication for ischemic stroke patients with AF, in ICH patients with AF are uncertain. PRESTIGE-AF is an international, phase 3b, multi-center, randomized, open, blinded end-point assessment (PROBE) clinical trial that compared the efficacy and safety of direct oral anticoagulants (DOACs) with no DOAC (either no antithrombotic treatment or any antiplatelet drug).

The background and experience of neuroscience teachers in Australian universities: A cross-sectional survey.

Neuroscience is an academic discipline taught within a broad range of university degrees and programs. The expertise and experience of neuroscience teaching staff contribute to the student's learning experience and knowledge acquisition. We undertook a survey to characterize the neuroscience teaching workforce and practices in Australian universities, and to investigate access to and deficiencies in neuroscience teaching resources and training.
