J Speech Lang Hear Res 2021 May 10:1-20. Epub 2021 May 10.

Department of Speech, Language, and Hearing Sciences, Auburn University, AL.

Purpose The aim of this study was to examine the influence of menstrual cycle phases (follicular, ovulatory, luteal, and ischemic) and hormone levels (estradiol, testosterone, progesterone, and neuropeptide Y) on vocal fold vibrations in reproductive and postmenopausal women. Method Glottal area waveforms were extracted from high-speed videoendoscopy during sustained phonation, inhalation phonation, and voice onset/offset in the reproductive ( = 15) and postmenopausal ( = 13) groups. Linear mixed-model analysis was conducted to evaluate hormone levels and high-speed videoendoscopy outcome variables between the reproductive and postmenopausal groups. Read More

The novel vasopressin receptor (V1aR) antagonist SRX246 reduces anxiety in an experimental model in humans: a randomized proof-of-concept study.

Psychopharmacology (Berl) 2021 May 10. Epub 2021 May 10.

National Institute of Mental Health, Bethesda, MD, USA.

Rationale: Arginine vasopressin (AVP) is a neuropeptide that modulates both physiological and emotional responses to threat. Until recently, drugs that target vasopressin receptors (V1a) in the human central nervous system were unavailable. The development of a novel V1a receptor antagonist, SRX246, permits the experimental validation of vasopressin's role in the regulation of anxiety and fear in humans. Read More

Effect of KBP-5074 on Blood Pressure in Advanced Chronic Kidney Disease: Results of the BLOCK-CKD Study.

Hypertension 2021 May 10:HYPERTENSIONAHA12117073. Epub 2021 May 10.

Department of Medicine, University of Michigan School of Medicine, Ann Arbor (B.P.).

In patients with resistant or poorly controlled hypertension and advanced chronic kidney disease, mineralocorticoid receptor antagonists are recommended; however, hyperkalemia limits their use. BLOCK-CKD was a phase 2b, multicenter, randomized, double-blind, placebo-controlled, parallel-group study that evaluated the safety, efficacy, and pharmacokinetics of KBP-5074, a nonsteroidal mineralocorticoid receptor antagonist, for uncontrolled hypertension in patients with stage 3b/4 chronic kidney disease. The study tested the hypothesis that addition of KBP-5074 to standard treatment lowers blood pressure without increased risk of hyperkalemia. Read More

Design and rationale of the EMPA-VISION trial: investigating the metabolic effects of empagliflozin in patients with heart failure.

ESC Heart Fail 2021 May 6. Epub 2021 May 6.

Oxford Centre for Clinical Magnetic Resonance Research (OCMR), Division of Cardiovascular Medicine, Radcliffe Department of Medicine, University of Oxford, John Radcliffe Hospital, Headley Way, Oxford, OX3 9DU, UK.

Aims: Despite substantial improvements over the last three decades, heart failure (HF) remains associated with a poor prognosis. The sodium-glucose co-transporter-2 inhibitor empagliflozin demonstrated significant reductions of HF hospitalization in patients with HF independent of the presence or absence of type 2 diabetes mellitus in the EMPEROR-Reduced trial and cardiovascular mortality in the EMPA-REG OUTCOME trial. To further elucidate the mechanisms behind these positive outcomes, this study aims to determine the effects of empagliflozin treatment on cardiac energy metabolism and physiology using magnetic resonance spectroscopy (MRS) and cardiovascular magnetic resonance (CMR).
