Cocoa-flavanols enhance moderate-intensity pulmonary [Formula: see text] kinetics but not exercise tolerance in sedentary middle-aged adults.

Eur J Appl Physiol 2021 May 10. Epub 2021 May 10.

School of Sport and Exercise Science, Liverpool John Moores University, Byrom Street, Liverpool, L3 3AF, UK.

Introduction: Cocoa flavanols (CF) may exert health benefits through their potent vasodilatory effects, which are perpetuated by elevations in nitric oxide (NO) bioavailability. These vasodilatory effects may contribute to improved delivery of blood and oxygen (O) to exercising muscle.

Purpose: Therefore, the objective of this study was to examine how CF supplementation impacts pulmonary O uptake ([Formula: see text]) kinetics and exercise tolerance in sedentary middle-aged adults. 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

Ann Palliat Med 2021 Apr;10(4):4994-4998

Department of Gastrointestinal Surgery, The First Affiliated Hospital, Chongqing Medical University, Chongqing, China.

Gastrointestinal stromal tumor (GIST) is the most common type of gastrointestinal mesenchymal tumor. Fewer than 2% of patients with metastatic GIST treated with imatinib experience a pathologic complete response. Furthermore, response to imatinib and subsequent-line tyrosine kinase inhibitor is limited by most patients developing drug resistance; median time to progression is 2 years for imatinib, and about half a year for sunitinib and regorafenib.

Eltrombopag for Post-Transplantation Thrombocytopenia: Results of Phase II Randomized, Double-Blind, Placebo-Controlled Trial.

Transplant Cell Ther 2021 May 6;27(5):430.e1-430.e7. Epub 2021 Feb 6.

Department of Stem Cell Transplantation and Cellular Therapy, The University of Texas MD Anderson Cancer Center, Houston, Texas. Electronic address:

Prolonged thrombocytopenia occurs in up to 37% of patients after hematopoietic stem cell transplantation (HSCT) and is associated with adverse prognosis and increased risk of bleeding. Eltrombopag, a thrombopoietin receptor agonist, can increase platelet counts in thrombocytopenic patients. We conducted a phase II study, adaptively randomizing patients at ≥35 days post-HSCT to receive placebo or eltrombopag at a platelet count ≤20,000/µL for 7 days or platelet transfusion-dependent and a neutrophil count ≥1500/µL.

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).

Int J Clin Pract 2021 May 7:e14334. Epub 2021 May 7.

Nutrition Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.

Background: Type 2 diabetes (T2D) is a metabolic disorder that is related to hyperglycemia, hyperlipidemia, and liver dysfunction and has detrimental effects on a patient's mental health. Hence, the current study investigated the effects of saffron supplementation on dietary intake, anthropometric measures, mood, sleep quality, and metabolic biomarkers in overweight/obese patients with T2D.

Novel application of a discrete time-to-event model for randomized oral immunotherapy clinical trials with repeat food challenges.

Stat Med 2021 May 6. Epub 2021 May 6.

Quantitative Sciences Unit, Division of Biomedical Informatics Research, Department of Medicine, Stanford University, Palo Alto, California, USA.

The evaluation of double-blind, placebo-controlled food challenges (DBPCFC) generally focuses on a participant passing a challenge at a predetermined dose, and does not consider the dose of reaction for those who fail or are censored due to study discontinuation. Further, a number of food allergy trials have incorporated multiple DBPCFCs throughout the duration of the study in order to evaluate changes in reaction over time including sustained unresponsiveness from treatment. Outcomes arising from these trials are commonly modeled using Chi-squared or Fisher's exact tests at each time point. Read More

Front Pharmacol 2021 20;12:652688. Epub 2021 Apr 20.

GlobalCures, Inc., Newton, MA, United States.

Fluvoxamine is a well-tolerated, widely available, inexpensive selective serotonin reuptake inhibitor that has been shown in a small, double-blind, placebo-controlled, randomized study to prevent clinical deterioration of patients with mild coronavirus disease 2019 (COVID-19). Fluvoxamine is also an agonist for the sigma-1 receptor, through which it controls inflammation. We review here a body of literature that shows important mechanisms of action of fluvoxamine and other SSRIs that could play a role in COVID-19 treatment. Read More
