Improving primary aldosteronism diagnosis and treatment: outcomes from an endocrine hypertension service

Internal Medicine Journal, EarlyView.
Abstract Aims To evaluate the sustained impact of the Endocrine Hypertension Service on primary aldosteronism (PA) diagnosis and management over a subsequent 3‐year period. Background PA is a prevalent yet underdiagnosed cause of secondary hypertension, associated with increased cardiovascular, renal and metabolic risk. Limited awareness, resources and

Refining Residual Ischemic Stroke Risk in Anticoagulated Atrial Fibrillation Using Index Outpatient LA Diameter: The CHA2DS2‐VALa Score

Journal of Cardiovascular Electrophysiology, EarlyView.
In anticoagulated atrial fibrillation, residual ischemic stroke risk persists despite guideline‐directed therapy. In this single‐center cohort, an enlarged index outpatient left atrial diameter independently predicted stroke and improved risk stratification when added to CHA2DS2‐VA (CHA2DS2‐VALa), supporting a simple, clinically implementable ...

Risk Factors and Management of Gingival Enlargement: A Systematic Review and Meta‐Analysis

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Objective To identify risk factors/indicators of gingival enlargement (GE) and to summarise evidence for its management. Methods A systematic review was undertaken following PRISMA guidelines and divided into PECOTS and PICOTS questions, related to risk factors/indicators and treatment studies, respectively.

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

The Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

Competitive binding experiments reveal differential interactions for dihydropyridine calcium channel activators and antagonists at dihydropyridine receptors on mouse brain membranes

, 1994
The binding of the dihydropyridine (±)-202-791 and its corresponding calcium channel activating and calcium channel antagonist enantiomers ((+)-S-202-791 and (−)-R-202-791, respectively) to dihydropyridine receptors on mouse brain membranes was studied ...

Diisopropyl 1-(4-methoxyphenyl)-2,6-dimethyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate

Acta Crystallographica Section E, 2011
In the title compound, C28H32N2O7, the 1,4-dihydropyridine ring adopts a flattened boat conformation. The two benzene rings are approximately perpendicular to the dihydropyridine ring, forming dihedral angles of 84.29 (9) and 82.96 (9)

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session
