Effect of Remote Ischemic Conditioning on the Form and Function of Red Blood Cells in Patients With Acute Ischemic Stroke.

Department of Neurology, Medical College of Georgia, Augusta University. (M.B.K., B.B., D.C.H.).
Background: Remote ischemic conditioning (RIC) is a simple and low-cost intervention that is thought to increase collateral blood flow through the vasodilatory effects of nitric oxide (NO) produced by the endothelium and red blood cells (RBCs). This study aims to investigate whether RIC affects RBC deformability and levels of NO and nitrite in patients with ischemic stroke.
Methods: This is a predefined substudy to the RESIST (Remote Ischemic Conditioning in Patients With Acute Stroke Trial) randomized clinical trial conducted in Denmark.

A consistent area of interest since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been the sequence composition of the virus and how it has changed over time. Many resources have been developed for the storage and analysis of SARS-CoV-2 data, such as GISAID (Global Initiative on Sharing All Influenza Data), NCBI, Nextstrain, and outbreak.info.

Objectives: Chronic Kidney Disease (CKD) has been associated with a prothrombotic state. CKD affects hemostasis through altered platelet function and coagulation factors. Traditional tests provide limited insight into these changes.

The γ-carboxylation of glutamate residues enables Ca-mediated membrane assembly of protein complexes that support broad physiological functions including hemostasis, calcium homeostasis, immune response, and endocrine regulation. Modulating γ-carboxylation level provides prevalent treatments for hemorrhagic and thromboembolic diseases. This unique posttranslational modification requires vitamin K hydroquinone (KH) to drive highly demanding reactions catalyzed by the membrane-integrated γ-carboxylase (VKGC).

Department of Orthopaedics, Sports Medicine Research Institute, The Ohio State University Wexner Medical Center, Columbus, OH, USA.
Goal: Cost-saving initiatives targeting surgical supplies management have become increasingly common to address rising healthcare costs. However, few studies provide details on hospital stakeholder experiences or learnings from implementing such initiatives. Thus, we sought to evaluate hospital stakeholder satisfaction with conversion to a sole supplier for hemostasis products, in addition to economic and clinical impacts, to help develop best practices for implementation.
