Mammals have evolved a complex system for controlling bone remodeling. Babies require calcium for healthy bones and they obtain it from their mother's milk. Nursing mothers release calcium from their bones. Surprisingly, however, the same system also plays a key part in the control of fever and of female body temperature. This finding is reported in a paper in this week's issue of Nature from Josef Penninger's group at the IMBA in Vienna, Austria. http://www.physorg.com/news178377435.html Medicine & Health Wed, 25 Nov 2009 13:18:13 EST news178377435 Animal studies suggest that adding flaxseed oil to the diet could reduce the risk of osteoporosis in post-menopausal women and women with diabetes, according to a report to be published in the International Journal of Food Safety, Nutrition and Public Health. http://www.physorg.com/news178208985.html Medicine & Health Mon, 23 Nov 2009 15:00:01 EST news178208985 Many biological processes are controlled by small molecules known as microRNAs, which work by suppressing the expression of specific sets of genes. Xiang-Hang Luo and colleagues, at Second Xiangya Hospital of Central South University, People's Republic of China, have now identified a previously unknown microRNA (miR-2861) as crucial to bone maintenance in mice and humans. Of clinical importance, expression of functional miR-2861 was absent in two related adolescents with primary osteoporosis. http://www.physorg.com/news177620522.html Medicine & Health Mon, 16 Nov 2009 19:30:03 EST news177620522 Aggressively managing patients at risk for osteoporosis could reduce the hip fracture rate in the United States by 25 percent, according to a Kaiser Permanente study published in the November issue of the Journal of Bone & Joint Surgery. The first step must be a more active role by orthopedic surgeons in osteoporosis disease management, researchers say. http://www.physorg.com/news176374147.html Medicine & Health Mon, 02 Nov 2009 09:00:01 EST news176374147 A recent study determined glucocorticoid-induced osteoporosis (OP) is now treatable with Teriparatide, a synthetic form of the human parathyroid hormone. Researchers found patients with glucocorticoid-induced OP who were treated with teriparatide for 36 months had a greater increase in bone mineral density (BMD) and fewer new vertebral fractures than those treated with alendronate. The findings of this study are published in the November issue of Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR). http://www.physorg.com/news176014810.html Medicine & Health Thu, 29 Oct 2009 06:50:02 EST news176014810 Celiac disease (CD) is an inherited intestinal disorder characterized by life-long intolerance to the ingestion of gluten, a protein found in wheat, rye, and barley. Although CD can be diagnosed at any age, it commonly occurs during early childhood (between 9 and 24 months). Reduced bone mineral density is often found in individuals with CD. A new article in the journal Nutrition Reviews examines the literature on the topic and reveals that a gluten-free diet can affect children's recovery. http://www.physorg.com/news174225813.html Medicine & Health Thu, 08 Oct 2009 13:20:01 EST news174225813 People with coeliac disease may develop osteoporosis because their immune system attacks their bone tissue, a new study has shown. http://www.physorg.com/news174155269.html Medicine & Health Wed, 07 Oct 2009 17:28:10 EST news174155269 A study published in the October 2009 issue of the Journal of Bone and Joint Surgery suggests a disconnect between the way wrist-fracture patients and those with a spine or hip fracture are managed and evaluated. The study, conducted in 2007 among 97 percent of the women in Korea, reviewed the incidence of fractures around the hip, spine, and wrist in female patients age 50 and older and the prescription frequencies of bone density scans for osteoporosis, along with the use of medications for its treatment. http://www.physorg.com/news173623898.html Medicine & Health Thu, 01 Oct 2009 14:40:01 EST news173623898 A new audit report issued by the International Osteoporosis Foundation (IOF) today shows that osteoporosis is a serious and growing problem throughout Asia. http://www.physorg.com/news172819492.html Medicine & Health Tue, 22 Sep 2009 06:25:22 EST news172819492 Dietary supplements claiming to help postmenopausal women with bone health may not be doing what they say, according to new research from Purdue University. http://www.physorg.com/news171119366.html Medicine & Health Wed, 02 Sep 2009 14:12:00 EST news171119366 Standardized rates of hip fracture have steadily declined in Canada since 1985, with a more rapid decline between 1996 and 2005 and a more marked decrease among individuals age 55 to 64 years, according to a report in the August 26 issue of JAMA. http://www.physorg.com/news170437598.html Medicine & Health Tue, 25 Aug 2009 16:47:49 EST news170437598 Scientists investigating the effects of cannabis on bone health have found that its impact varies dramatically with age. http://www.physorg.com/news169375322.html Medicine & Health Thu, 13 Aug 2009 10:00:06 EST news169375322 Vertebral and hip fractures are associated with an increased risk of death, found a new study of 7753 people in Canada aged 50 years and older published in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/press/cmaj081720.pdf. According to the results, approximately 25% of people (both men and women) living in the community who develop a hip fracture and 16% who develop a spine fracture will die over a 5 year period. http://www.physorg.com/news168609431.html Medicine & Health Tue, 04 Aug 2009 13:07:51 EST news168609431 Osteoporosis comes from a Latin term which means "holes in the bone." In reality it is a skeletal disease characterized by low bone mineral density and structural deterioration of bone, leading to bone weakness and increased risk of fracture. Untreated, osteoporosis can lead to fragility fractures, which are broken bones that occur from falls at a standing height. These most commonly occur at the wrist, hip, or spine. http://www.physorg.com/news168104676.html Medicine & Health Wed, 29 Jul 2009 16:45:25 EST news168104676 An osteoporosis drug proven to save lives after hip fractures may do so by strengthening the body's immune system, according to geriatrics researchers at Duke University Medical Center. http://www.physorg.com/news166885585.html Medicine & Health Wed, 15 Jul 2009 14:07:09 EST news166885585 Researchers at the University of Alabama at Birmingham (UAB) have discovered a molecular coupling factor that helps bones grow and remodel themselves to stay strong, a finding that could lead to better bone-building therapies and new osteoporosis drugs, the researchers said. http://www.physorg.com/news166270408.html Medicine & Health Wed, 08 Jul 2009 11:13:59 EST news166270408 Monitoring bone mineral density in postmenopausal women taking osteoporosis drugs (bisphosphonates) is unnecessary and potentially misleading, concludes a study published on BMJ.com today. http://www.physorg.com/news165005376.html Medicine & Health Tue, 23 Jun 2009 20:40:01 EST news165005376 (AP) -- It isn't just the thunder thighs that shrink after obesity surgery. Melting fat somehow thins bones, too. Doctors don't yet know how likely patients' bones are to thin enough to break in the years after surgery. But one of the first attempts to tell suggests they might have twice the average person's risk, and be even more likely to break a hand or foot. http://www.physorg.com/news164300455.html Medicine & Health Mon, 15 Jun 2009 16:30:01 EST news164300455 After weight loss surgery, people have nearly twice the expected risk of breaking a bone and an even higher risk of a foot or hand fracture, a new study has found. http://www.physorg.com/news163939075.html Medicine & Health Thu, 11 Jun 2009 11:38:32 EST news163939075 Rheumatoid arthritis (RA), the most common form of inflammatory arthritis, affects almost three percent of people over age 65. RA patients experience pain, functional limitations and two forms of disabling bone disease: focal erosions and osteoporosis. After five years of disease, up to 50 percent of RA patients show evidence of focal erosions and RA doubles the risk of osteoporosis and fractures. A new study examined the relationship between these two RA-related processes, in the hopes of providing insight into the underlying pathophysiology of RA-related bone disease. The study was published in the June issue of Arthritis & Rheumatism . http://www.physorg.com/news163095769.html Medicine & Health Mon, 01 Jun 2009 17:24:49 EST news163095769 (PhysOrg.com) -- Hyperkyphosis, or "dowager's hump" -- the exaggerated forward curvature of the upper spine seen commonly in elderly women -- may predict earlier death in women whether or not they have vertebral osteoporosis, UCLA researchers have found. http://www.physorg.com/news162139052.html Medicine & Health Thu, 21 May 2009 15:37:57 EST news162139052 (PhysOrg.com) -- Osteoporosis and periodontitis are common diseases whose sufferers must cope with weakness, injury and reduced function as they lose bone more quickly than it is formed. While the mechanism of bone destruction in these diseases is understood, scientists have had less information about how bone formation is impaired. http://www.physorg.com/news161949438.html Medicine & Health Tue, 19 May 2009 10:58:28 EST news161949438 Osteoporosis, or bone loss, is a disease that is most common in the elderly population, affecting women more often than men. Until now, it was not clear exactly how the disease develops. Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now elucidated a molecular mechanism which regulates the equilibrium between bone formation and bone resorption. Dr. Jeske J. Smink, Dr. Valérie Bégay, and Professor Achim Leutz were able to show that two different forms of a gene switch - a short isoform and a long isoform - determine this process. The MDC researchers hope these findings will lead to new therapies for this bone disease. http://www.physorg.com/news161528731.html Medicine & Health Thu, 14 May 2009 14:05:49 EST news161528731 A new study provides doctors with guidelines on when to repeat bone mineral density (BMD) tests for their patients. http://www.physorg.com/news161360289.html Medicine & Health Tue, 12 May 2009 15:18:33 EST news161360289 The advice and treatment given to patients with vertebral compression fractures is not satisfactory. A thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden, shows that the majority of patients still have severe pain one year after the fracture. http://www.physorg.com/news159700955.html Medicine & Health Thu, 23 Apr 2009 10:23:18 EST news159700955 Rarely will physicians use the word "miraculous" when discussing patient recoveries. But that's the very phrase orthopaedic physicians and scientists are using in upstate New York to describe their emerging stem cell research that could have a profound impact on the treatment of bone injuries. Results from preliminary work being released todayshow patients confined to wheelchairs were able to walk or live independently again because their broken bones finally healed. http://www.physorg.com/news158928137.html Medicine & Health Tue, 14 Apr 2009 11:43:01 EST news158928137 People who have osteoporosis are more likely to also have vertigo, according to a study published in the March 24, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology. http://www.physorg.com/news157044736.html Medicine & Health Mon, 23 Mar 2009 16:32:24 EST news157044736 While interferon gamma sounds like an outer space weapon, it's actually a hormone produced by our own bodies, and it holds great promise to repair bones affected by osteoporosis. In a new study published in the journal Stem Cells, researchers from the Research Institute of the McGill University Health Centre explain that tweaking a certain group of multipotent stem cells (called mesenchymal stem cells) with interferon (IFN) gamma may promote bone growth. http://www.physorg.com/news155395155.html Medicine & Health Wed, 04 Mar 2009 13:19:48 EST news155395155 (PhysOrg.com) -- You may be wondering at this point whether to toss those vitamins into your mouth or into the trash. That's not surprising since several recent reports have called the value of vitamins into question, leaving people to wonder if it's time to ditch their supplements all together. http://www.physorg.com/news154023079.html Medicine & Health Mon, 16 Feb 2009 16:12:00 EST news154023079 A new study shows that osteoporotic fractures increase a person's risk of dying, even after relatively minor fractures if that person is elderly.
