    Latest Osteoporosis News - September 28th 2009

    General Osteoporosis and Lifestyle News

    Canadian newspaper The Star takes a look between the link between depression and osteoporosis. They stipulate that as bone disease affects your quality of life, it may lead to depression, and that the resultant change in hormones in ones bodies can lead to a further increase in bone degeneration. This site has an feature on osteoporosis and stress that you may like to read. The Star article refers to research that has found up to 9% of elderly women suffer from depression, many cases of which are linked to a persons lack of mobility, partially as a result of bone degeneration and bad diet. The article then goes on to discuss which came first, the osteoporosis or the depression, and takes a look at the viscous circle that many people find themselves within.

    The above news article mentioned the factor of bad diet, and its impact on both a persons physical and mental wellbeing. The Chicago Tribune runs a feature on how to boost calcium in your diet. The article interviews a nutritionist Wendy Brazil and asks her questions about calcium intake with relation to bone health. Wendy recommends that people with weak bones have an intake of between 1200 and 1500mg of calcium; and upto 2000mg for people who have advanced bone loss. She recommends that people incorporate cottage cheese, milk, yogurt, almonds, broccoli and tofu as natural sources of calcium. The article is very highly recommended as she mentions that fact that the body can only absorb 500mg of calcium at a time, so there is little point in taking those 1200mg calcium tablets!

    Staying on the subject of a diet for strong bones the Baltimore sun takes a look at what fruit and vegetables are good for maintaining healthy bones. However they do it at the expense of a calcium intake from dairy products, with a low acid diet. The theory is that eating foods rich in alkaline can higher the pH of the blood (make it less acidic), thus leading to less bone loss. However although there is some evidence for this in the literature (especially with regards to taking potassium bicarbonate supplements) at the present time this site sees a natural intake of both calcium and vitamin D as being much more important than the benefits of a low acid diet. You could of course combine the two by getting your calcium from broccoli and almonds as opposed from milk and other dairy products.

    In osteoporosis drugs news, Bloomberg reports that Eli Lily has defended its patent for the Evista drug; this has stopped the Israel based Teva company from producing a cheap generative form of the osteoporosis drug in the United States until 2014. This is very good news for Eli Lily as they sell around $650 million worth of the drug each year.

    Latest Osteoporosis Research

    Figtree and colleagues at the university of Sydney took a look at Estrogen receptor polymorphisms and how they may play a role in therapy and disease. They report therir findings in the Novemebr issue of Recent Patents in DNA and Gene Sequence. The work is based upon the fact that natural changes in the genes that code for estrogen signalling proteins will lead to differences in hormone sensitivity. They identified many natural polymorphisms in both alpha and beta estrogen receptors, and speculate that some of them may have a biological impact, especially with regards to estrogen related diseases such as osteoporosis and breast cancer. They also state that these polymorphisms in estrogen receptors may lead to differences in sensitivities of the contraceptive pill and of hormone replacement treatments. They have put forward some of the identified genetic variations of the estrogen receptors for patents.

    McNicoll and Heaney of Queen's University in Northern Ireland report in the current drug safety journal of the link between bisphosphonate use and corticosteroids in pre-menopausal women. They discuss the link between glucocorticoid therapy and osteoporosis, especially with regards to findings from animals. The aim of their review is to give an overview of the risks of taking bisphosphonates in pre-menopausal women.

    As always I end the osteoporosis newsletter with an article from the osteoporosis advice website that readers should find useful. As much of this weeks osteoporosis news has been dedicated to calcium, this week I recommend that you read up on dietary calcium. Did you know that not all calcium is absorbed in the body the same way, and that the body can only handle so much at once? After reading this section of the site you should hopefully have a better understanding of how the body handles calcium.
