Hyperuricemia Is Associated With Higher Mortality in Non-diabetic Heart Failure Patients.

Introduction: Hyperuricemia (HU) is associated with an increased risk of incident heart failure (HF) and adverse HF outcomes. Patients with diabetes mellitus (DM) have a greater prevalence of HU.

Aims: We evaluated the prognostic impact of HU in patients with HF according to the coexistence of DM.

Platelet distribution width-a prognosis marker in patients with chronic heart failure.

Background: Increased levels of platelet distribution width (PDW) can predict cardiac death and infarction recurrence in acute myocardial infarction. PDW appears to be a prognosis marker in acute heart failure (HF); however, its impact on chronic HF is still unknown. We investigated the impact of PDW on chronic HF.

Preserved working memory performance along with subcortical modulation during peri-ictal phases in spontaneous migraine attacks.

Objective: To analyze cognitive performance and brain activation during a working memory task in patients with migraine during various phases of the migraine cycle and compare to healthy participants.

Background: Cognitive difficulties reported during migraine attacks remain poorly understood, despite evidence that the lateral frontoparietal network undergoes reversible disturbances and decreased activation during attacks. Recent findings in resting state functional magnetic resonance imaging suggest that brain areas involved in this network interact with subcortical regions during spontaneous migraine attacks.
