Novel Approaches to Restore Pancreatic Beta-Cell Mass and Function.

Handb Exp Pharmacol 2021 Jun 11. Epub 2021 Jun 11.

Institute for Vascular and Islet Cell Biology, German Diabetes Center (DDZ), Leibniz Center for Diabetes Research at Heinrich-Heine-University, Düsseldorf, Germany.

Beta-cell dysfunction and beta-cell death are critical events in the development of type 2 diabetes mellitus (T2DM). Therefore, the goals of modern T2DM management have shifted from merely restoring normoglycemia to maintaining or regenerating beta-cell mass and function. In this review we summarize current and novel approaches to achieve these goals, ranging from lifestyle interventions to N-methyl-D-aspartate receptor (NMDAR) antagonism, and discuss the mechanisms underlying their effects on beta-cell physiology and glycemic control.

Advances in Revascularization for Peripheral Artery Disease: Revascularization in PAD.

Circ Res 2021 Jun 10;128(12):1885-1912. Epub 2021 Jun 10.

Division of Vascular and Endovascular Surgery, University of California, San Francisco (P.A.S., M.S.C.).

Effective revascularization of the patient with peripheral artery disease is about more than the procedure. The approach to the patient with symptom-limiting intermittent claudication or limb-threatening ischemia begins with understanding the population at risk and variation in clinical presentation. The urgency of revascularization varies significantly by presentation; from patients with intermittent claudication who should undergo structured exercise rehabilitation before revascularization (if needed) to those with acute limb ischemia, a medical emergency, who require revascularization within hours.

Using Patient-Reported Outcomes toAssess Healthcare Quality: Toward Better Measurement of Patient-Centered Care in Cardiovascular Disease.

Methodist Debakey Cardiovasc J 2021 Apr;17(1):e1-e9

Saint Luke's Mid America Heart Institute, University of Missouri Kansas City,Kansas City, Missouri.

Patient-reported outcomes (PROs) are elicited directly from patients so they can describe their overall health status, including their symptoms, function, and quality of life. While commonly used as end points in clinical trials, PROs can play an important role in routine clinical care, population health management, and as a means for quantifying the quality of patient care. In this review, we propose that PROs be used to improve patient-centered care in the treatment of cardiovascular diseases given their importance to patients and society and their ability to improve doctor- provider communication.
