Every animal species has a signature blood glucose level or glycemic set point. These set points are different, and the normal glycemic levels (normoglycemia) of one species would be life threatening for other species. Mouse normoglycemia can be considered diabetic for humans. The biological determinants of the glycemic set point remain unclear. Here we show that the pancreatic islet imposes its glycemic set point on the organism, making it the bona fide glucostat in the body. Moreover, and in contrast to rodent islets, glucagon input from the alpha cell to the insulin-secreting beta cell is necessary to fine-tune the distinctive human set point. These findings affect transplantation and regenerative approaches to treat diabetes because restoring normoglycemia may require more than replacing only the beta cells. Furthermore, therapeutic strategies using glucagon receptor antagonists as hypoglycemic agents need to be reassessed, as they may reset the overall glucostat in the organism.

Department of Surgery, University of Virginia, Charlottesville, Virginia, USA.
Background: While existing risk calculators focus on mortality and complications, elderly patients are concerned with how operations will affect their quality of life, especially their independence. We sought to develop a novel clinically relevant and easy-to-use score to predict elderly patients' loss of independence after gastrointestinal surgery.
Methods: This retrospective cohort study included patients age ≥ 65 years enrolled in the American College of Surgeons National Surgical Quality Improvement Program database and Geriatric Pilot Project who underwent pancreatic, colorectal, or hepatic surgery (January 1, 2014- December 31, 2018).

Background: Health professionals play a key role in promoting health literacy, as they continue to be one of the main points of contact and most trusted source of information for healthcare users on questions and concerns regarding health and disease. To adequately support individuals in dealing with health information and services and to strengthen health literacy, health professionals need a corresponding set of knowledge, skills, and attitudes, hence they need a wide range of health literacy competencies. Despite their crucial role in guiding and supporting patients and their relatives in terms of health-related information and services, in-depth studies on health literacy competencies of health professionals are still scarce.

Background: The identification of the key factors that affect academic success in nursing students, including health-related quality of life, academic burnout, and academic motivation, has been of the utmost importance to date. In this context, the present study sought to examine the relationship between health-related quality of life and academic success, with academic burnout and academic motivation mediating that relationship.
Methods: This analytical cross-sectional study included 262 eligible nursing students selected through convenience sampling from the School of Nursing and Midwifery at Shahid Beheshti University of Medical Sciences, Tehran, Iran.
