Obesity hormone adiponectin increases the risk of osteoporosis in the elderly

02.11.2011
While obesity is a well-known cause of cardiovascular disease, research from the Sahlgrenska Academy at the University of Gothenburg, Sweden, has now revealed that the body’s obesity hormones – adiponectin - are also linked to osteoporosis and an increased risk of fractures.

Our skeleton is more than just bones, vertebrae and joints. In fact, it is an active organ that is constantly linked to our brain, our muscles and our fatty tissue. Stem cells – the body’s most important cells – are formed in the skeleton, which is also home to hormones that control the body’s blood sugar and obesity by sending signals to other organs.

New research has now revealed that raised levels of obesity hormone in the blood could be connected to osteoporosis.

Dan Mellström, a researcher at the Sahlgrenska Academy and consultant at Sahlgrenska University Hospital, is a leading expert in osteoporosis. As part of an international research project studying the risk factors associated with osteoporosis in elderly men, he and his colleagues have been looking into the obesity hormone adiponectin. This research has now shown that people with raised levels of this hormone also have more fragile skeletons and more fractures, as well as reduced muscle strength and lower muscle mass, increasing the risk of fractures. High adiponectin also seems to be related to increased functional ageing.

“High levels of adiponectin in the elderly seem to be associated with both reduced functioning of the musculature and a more fragile skeleton,” says Mellström. “This means a higher risk of fractures and falls, and also increased mortality.”

The results are based on the Mr OS study, led from the Sahlgrenska Academy, which is looking into the risk factors for osteoporosis in elderly men. The study includes around 11,000 men in Sweden, the USA and Hong Kong.

OSTEOPOROSIS
Osteoporosis, or brittle bone disease, involves a reduction in the strength of the skeleton as a result of illness or ageing. The disorder causes much suffering for those affected it and also considerable costs to society. It is estimated that one third of all care places in Swedish orthopaedic clinics go to patients with hip fractures or complications from hip fractures.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
