High-frequency episodic migraine: Time for its recognition as a migraine subtype?

Background: High-frequency episodic migraine (HFEM) has gained attention in the field of headache research and clinical practice. In this narrative review, we analyzed the available literature to assess the evidence that could help decide whether HFEM may represent a distinct clinical and/or biological entity within the migraine spectrum.

Methods: The output of the literature search included 61 papers that were allocated to one of the following topics: (i) socio-demographic features and burden; (ii) clinical and therapeutic aspects; (iii) pathophysiology; and (iv) classification.

Glutamine sensing licenses cholesterol synthesis.

The mevalonate pathway produces essential lipid metabolites such as cholesterol. Although this pathway is negatively regulated by metabolic intermediates, little is known of the metabolites that positively regulate its activity. We found that the amino acid glutamine is required to activate the mevalonate pathway.

Differences in Trunk Acceleration-Derived Gait Indexes in Stroke Subjects with and without Stroke-Induced Immunosuppression.

: Stroke-induced immunosuppression (SII) represents a negative rehabilitative prognostic factor associated with poor motor performance at discharge from a neurorehabilitation unit (NRB). This study aims to evaluate the association between SII and gait impairment at NRB admission. : Forty-six stroke patients (65.

Practice makes perfect: the development of a medical student-led crowdsourced question bank for self-study in undergraduate medical education.

The development of multiple-choice questions (MCQs) for undergraduate medical education study purposes is resource intensive. Commercially available question banks are typically expensive, only available in English, and may not be aligned with medical school learning objectives. Here, we introduce : a student-led, bilingual study resource curated to a Canadian undergraduate medicine curriculum (www.
