Today, The Endocrine Society released a clinical practice guideline (CPG) providing recommendations on settings where patients are most likely to benefit from continuous glucose monitoring (CGM).
The most common way to self-check blood glucose levels is to prick the skin to get a drop of blood, put the blood on a test strip, and insert it in a glucose meter. CGM, though, measures glucose in the interstitial fluid—the fluid between body cells just under the skin. People with both type 1 and type 2 diabetes use the results of blood glucose tests to make decisions about food, medicines and exercise.
"There are some caveats to consider before accepting continuous monitoring of glucose as a routine measure to improve glycemic control in diabetes," said David Klonoff, MD, of Mills-Peninsula Health Services in San Mateo, California and chair of the task force that authored the CPG. "There are still concerns about the high costs of CGM and the accuracy of the various systems available. However, the new CPG shows that CGM can be a beneficial tool to help maintain target levels of glycemia and limit the risk of hypoglycemia."
Recommendations from The Endocrine Society's CPG include:
Use of CGM with currently approved devices in children and adolescents with type 1 diabetes mellitus (T1DM) because it will assist in maintaining target HbA1c levels while limiting the risk of hypoglycemia;
Use of CGM devices by adult patients with T1DM who have demonstrated they can use these devices on a nearly daily basis; and
Refrainment from using CGM alone for glucose management in the intensive care unit or operating room until further studies provide sufficient evidence for its accuracy and safety in those settings.
The Hormone Foundation, the patient education affiliate of The Endocrine Society, has published a companion patient guide to this CPG. The patient guide, which can be found online at www.hormone.org/glucose, explains how CGM works and who could most benefit from its use.
"Continuous Glucose Monitoring: An Endocrine Society Clinical Practice Guideline," is published in the October 2011 issue of the Journal of Clinical Endocrinology & Metabolism (JCEM), a publication of The Endocrine Society.
Other members of The Endocrine Society task force that developed this CPG include: Bruce Buckingham of Stanford University in California, Jens Christiansen of Aarhus University Hospital in Denmark; Victor Montori of Mayo Clinic in Rochester Minn.; William Tamborlane of Yale University in New Haven, Conn.; Robert A. Vigersky of Walter Reed National Military Medical Center in Bethesda, Maryland; and Howard Wolpert of the Joslin Diabetes Center in Boston, Mass.
The Society established the Clinical Practice Guideline (CPG) Program to provide endocrinologists and other clinicians with evidence-based recommendations in the diagnosis and treatment of endocrine-related conditions. Each CPG is created by a task force of topic-related experts in the field. Task forces rely on scientific reviews of the literature in the development of CPG recommendations. The Endocrine Society does not solicit or accept corporate support for its CPGs. All CPGs are supported entirely by Society funds.
Founded in 1916, The Endocrine Society is the world's oldest, largest and most active organization devoted to research on hormones and the clinical practice of endocrinology. Today, The Endocrine Society's membership consists of over 14,000 scientists, physicians, educators, nurses and students in more than 100 countries. Society members represent all basic, applied and clinical interests in endocrinology. The Endocrine Society is based in Chevy Chase, Maryland.

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.
If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
Researchers from Chalmers University of Technology have demonstrated a detector made from graphene that could revolutionize the sensors used in next-generation space telescopes. The findings were recently published in the scientific journal Nature Astronomy.
Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for...
A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.
In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...
A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.
Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...
