Tailoring diabetes treatment to older patients yields dramatic results

08.07.2013
More than a quarter of over 70s with type 2 diabetes could benefit simply from improving communication and education in the clinic, new research has revealed

More than a quarter of over 70s with type 2 diabetes could benefit simply from improving communication and education in the clinic, new research has revealed. A study led by the University of Exeter Medical School and published in The Lancet found that 27 percent achieved better glycaemic control through individualised care alone.

At the moment, patients over the age of 70 are treated using a blanket method of aggressively reducing blood glucose levels, but that does little to take their complex needs into account.

Dr David Strain, from the University of Exeter Medical School, who led the study, said: "People over the age of 70 are more likely to have multiple complications, such as heart disease, as well as type 2 diabetes. Yet perversely, these patients have so far been excluded from clinical trials, precisely because of these complications. It means they are generally treated with a 'one-size-fits-all' approach. We found that simply by individualising goals and setting realistic targets, then spending time talking to patients rather than aggressively chasing targets resulted in nearly a quarter of patients achieving better glycaemic control, without the need for medication."

Type 2 diabetes is one of the most common chronic disorders in older adults. The number of people over the age of 65 has grown worldwide, and could now be as high as one in five. Older patients are more susceptible to complications caused by hyperglycaemia, when blood sugar levels are not properly balanced. These complications can increase the risk of falls and dizziness.

The situation has led to calls for treatment to be individualised, but so far evidence to support the case has been lacking. The research was funded by Novartis Pharma AG, the company that produces the antihypertensive agent vildagliptin. In the study, 139 patients from across Europe were given 50mg of the drug twice a day, while the same number of comparable patients were given a placebo, plus individualised care. All patients were over the age of 70, and were included in the trial because their GP thought they needed more medication. The findings were stark: those patients who were given the drug were three times more likely to reach their target than those who were not involved in the study, and received standard treatment. But researchers were particularly excited by the result from the placebo group, in which 27 percent met their targets without any medication.

Dr Strain said: "This was a small trial, but the results were quite dramatic, and it is the first strong evidence that individualised care can make a huge difference to the lives of older patients with type 2 diabetes. We now need to build on this evidence with further research."

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
