Efficacy of Bilberry and Grape Seed Extract Supplement Interventions to Improve Glucose and Cholesterol Metabolism and Blood Pressure in Different Populations-A Systematic Review of the Literature.

Nutrients 2021 May 17;13(5). Epub 2021 May 17.

Rowett Institute, University of Aberdeen, Foresterhill, Aberdeen AB25 2ZD, UK.

Intervention with fruit extracts may lower glucose and lipid levels, as well as blood pressure. We reviewed the efficacy of bilberry and grape seed extracts to affect these outcomes across populations with varying health status, age and ethnicity, across intervention doses and durations, in 24 intervention studies with bilberry and blackcurrant ( = 4) and grape seed extract ( = 20). Bilberry and blackcurrant extract lowered average levels of glycated hemoglobin (HbA1c), at least in Chinese subjects, especially in those who were older, who were diagnosed with Type 2 Diabetes Mellitus (T2DM) and who were participating in longer-term studies.

Chronic valproic acid administration enhances oxidative stress, upregulates IL6 and downregulates Nrf2, Glut1 and Glut4 in rat's liver and brain.

Neuroreport 2021 Jul;32(10):840-850

Department of Physiology, College of Medicine and Health sciences, Sultan Qaboos University, Muscat, Oman.

Valproic acid (VPA) is a powerful antiepileptic drug that was associated with several neurological and hepatic problems especially with increasing its dose and duration. These problems may be metabolic in origin and related to glucose homeostasis. So, the present study investigated the effect of different doses and durations of VPA on the expression of glucose transporters (Glut1 and Glut4), oxidative stress and inflammatory cytokine (IL-6) in the liver and specific brain regions.

Evidence-Based Treatment and Monitoring Strategies for Dementia-Related Psychosis.

Clive Ballard

J Clin Psychiatry 2021 Apr 27;82(3). Epub 2021 Apr 27.

University of Exeter College of Medicine and Health, UK.

Atypical antipsychotics play a limited role in the management of dementia-related psychosis (DRP). Major adverse outcomes are associated with most antipsychotics in patients with dementia, and guidelines recommend that these drugs not be prescribed for long durations. When treating symptoms of DRP, clinicians should follow guidelines such as using medication only if the patient or others are in distress or danger and starting with low doses. Read More

Durability of VEGF Suppression With Intravitreal Aflibercept and Brolucizumab: Using Pharmacokinetic Modeling to Understand Clinical Outcomes.

Transl Vis Sci Technol 2021 Apr;10(4)

Medical Affairs Ophthalmology, Bayer Consumer Care AG, Basel, Switzerland.

Purpose: To investigate whether vascular endothelial growth factor (VEGF)-suppression durations contribute to our understanding of clinical trial outcomes by simulating vitreous molar concentrations (Cvm) of intravitreal aflibercept (IVT-AFL) and brolucizumab (IVT-BRO) using pharmacokinetic (PK) modeling.

Methods: A PK model simulated Cvm after single-dose IVT-AFL, IVT-BRO, and ranibizumab (IVT-RAN), and extrapolated intraocular VEGF-suppression thresholds and durations. Vitreous PK after multidose regimens used in studies of IVT-AFL versus IVT-BRO were simulated and compared with best-corrected visual acuity (BCVA) data. Read More

Glucocorticoid signaling in pancreatic islets modulates gene regulatory programs and genetic risk of type 2 diabetes.

PLoS Genet 2021 May 13;17(5):e1009531. Epub 2021 May 13.

Department of Pediatrics, University of California San Diego, La Jolla, California, United States of America.

Glucocorticoids are key regulators of glucose homeostasis and pancreatic islet function, but the gene regulatory programs driving responses to glucocorticoid signaling in islets and the contribution of these programs to diabetes risk are unknown. In this study we used ATAC-seq and RNA-seq to map chromatin accessibility and gene expression from eleven primary human islet samples cultured in vitro with the glucocorticoid dexamethasone at multiple doses and durations. We identified thousands of accessible chromatin sites and genes with significant changes in activity in response to glucocorticoids. Read More
