Characterizing apparent treatment resistant hypertension in the United States: insights from the All of Us Research Program.

Background: Hypertension (HTN) remains a significant public health concern and the primary modifiable risk factor for cardiovascular disease, which is the leading cause of death in the United States. We applied our validated HTN computable phenotypes within the All of Us Research Program to uncover prevalence and characteristics of HTN and apparent treatment-resistant hypertension (aTRH) in United States.

Methods: Within the All of Us Researcher Workbench, we built a retrospective cohort (January 1, 2008-July 1, 2023), identifying all adults with available age data, at least one blood pressure (BP) measurement, prescribed at least one antihypertensive medication, and with at least one SNOMED "Essential hypertension" diagnosis code.

Optimal hyperglycemia thresholds in patients undergoing chemotherapy: a cross sectional study of oncologists' practices.

Purpose: Neither the United States nor the European oncology guidelines include details for appropriate management of hyperglycemia in cancer patients. The aim was to identify fasting and random blood glucose thresholds, and hemoglobin A1c (HbA1c) targets used by oncologists in clinical practice when managing hyperglycemia in patients with cancer undergoing chemotherapy.

Methods: This national, cross sectional study utilized a questionnaire to collect oncologists' perceptions about optimal blood glucose thresholds and HbA1c targets in patients with cancer undergoing chemotherapy.

New insights on mucormycosis and its association with the COVID-19 pandemic.

COVID-19 continues to cause significant fatality worldwide. Glucocorticoids prove to play essential roles in COVID-19 management; however, the extensive use of steroids together with the virus immune dysregulation may increase the danger of secondary infections with mucormycosis, an angioinvasive fungal infection. Unfortunately, a definite correlation between COVID-19 and elevated mucormycosis infection cases is now clear worldwide.

A genetic insight into vitamin D binding protein and COVID-19.

It's since December 2019 that Corona virus disease (COVID-19) has emerged to be the global issue of concern. A "pandemic"; this is what WHO has declared about the COVID-19 outbreak on March 3rd, 2020. Vitamin D and its deficiency have recently been claimed to be one of the potential factors affecting COVID-19 risks and outcomes [1].

The impact of cholecalciferol on markers of vascular calcification in hemodialysis patients: A randomized placebo controlled study.

Background And Aim: Vascular calcification is an independent risk factor for cardiovascular diseases and all-cause mortality in end stage renal disease, and particularly in hemodialysis patients. Vitamin D deficiency has been shown to be associated with vascular calcification among this category of patients. Cholecalciferol or vitamin D3; the native inactivated 25-hydroxy vitamin D [25(OH)D], has been proposed to have a good impact on vascular calcification and vitamin D deficiency.

Effect of febuxostat on oxidative stress in hemodialysis patients with endothelial dysfunction: a randomized, placebo-controlled, double-blinded study.

Purpose: Oxidative stress, which is most likely a key mediator in the development of cardiovascular disease, is implicated in the progression and deterioration of chronic kidney disease. Patients on hemodialysis exhibit the excessive generation of oxidative stressors, which may also be responsible for the endothelial dysfunction prevalent in these patients. Febuxostat, an inhibitor of xanthine oxidase enzyme, is emerging as a novel drug in the amelioration of oxidative stress status.

Effect of Febuxostat on the Endothelial Dysfunction in Hemodialysis Patients: A Randomized, Placebo-Controlled, Double-Blinded Study.

Background: Endothelial dysfunction is an important risk factor for cardiovascular diseases to occur in end-stage renal disease patients. Febuxostat, being a novel xanthine oxidase inhibitor, is apparently having a beneficial role in improving the endothelial dysfunction; however, data among hemodialysis patients are still limited.

Methods: A prospective, placebo-controlled, block-randomized, double-blinded study was carried out to evaluate the effect of oral febuxostat on the endothelial dysfunction in hemodialysis patients.
