Splanchnic Venous Compression Enhances the Effects of ß‐Blockade in the Treatment of Postural Tachycardia Syndrome

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Splanchnic venous pooling induced by upright posture triggers a compensatory increase in heart rate (HR), a response that is exaggerated in patients with postural tachycardia syndrome.

Blood pressure effects of SGLT2 inhibitors and GLP‐1 receptor agonists: Mechanisms, trial evidence and Real‐world data

British Journal of Clinical Pharmacology, EarlyView.
SGLT2 inhibitors and GLP‐1 receptor agonists modestly lower blood pressure across diverse patient populations, including those without diabetes. These effects appear largely independent of glycaemic control and offer additive value in high‐risk patients with overlapping comorbidities.

Ictal semiology in fronto‐opercular epilepsy: A systematic review

Epileptic Disorders, EarlyView.
Abstract A systematic review of the ictal semiology of fronto‐opercular seizures in focal epilepsy was carried out to assess possible anatomical‐clinical correlations and help guide interpretation of ictal semiology during pre‐surgical evaluation. PubMed and Embase databases were searched using the following keywords: “fronto‐opercular OR frontal ...
