Vitamin D injection fails to prevent fractures in elderly people
An annual injection of vitamin D does not reduce the rate of bone fractures suffered by elderly people.
The finding is the result of a four-year long study in which scientists from the MRC Epidemiology Resource Centre at the University of Southampton compared the number of bone fractures experienced by elderly people who received a vitamin D injection with those of men and women who were given a placebo. They found no change in the rate of hip, wrist or other non-vertebral fractures between the two groups.
The study is published online by the journal Rheumatology and will appear in the journal's December issue.
The clinical trial involved 9,440 men and women aged over 75 living in the Wessex region. Vitamin D deficiency is common amongst elderly people and is thought to contribute to the risk of osteoporotic fractures - bones broken as they are weakened by osteoporosis. The injection of vitamin D, or placebo, was given at the same time as people received their annual flu vaccine. The study aimed to determine whether giving a vitamin D injection to the elderly at the same time would help to protect them against osteoporotic fractures.
'Unfortunately the results suggest that giving vitamin D in the form of an injection doesn't appear to be beneficial to older people,' commented Professor Cyrus Cooper, leader of the research team, Professor of Rheumatology and Director of the MRC Epidemiology Resource Centre at Southampton.
He continued: 'This is one of the largest studies of its kind and we have demonstrated quite conclusively that an annual intramuscular injection of vitamin D, given in association with influenza vaccination, is not effective at reducing fractures caused by osteoporosis among elderly people living in southern England.
'Although encouraging findings were obtained from a smaller European study, our results suggest that a programme of vitamin D injections would not be a justifiable use of stretched health care resources. Although vitamin D insufficiency is common among older people, the most effective means of correcting this would be by combined oral daily calcium and vitamin D supplements.'

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
