Electromagnetic radiation from cellular phones may adversely affect bone strength, suggests a study in the March Journal of Craniofacial Surgery. http://phys.org/news220453414.html Medicine & Health Sun, 27 Mar 2011 14:04:02 EST news220453414 Low bone mineral density in HIV-infected patients is common and raises concerns about increased risks of fracture. Although there have been several studies regarding bone mineral density, there have been few data on rates of fracture in this population. A new study published in Clinical Infectious Diseases and available online examined differences in the rates of bone fractures between HIV-infected patients and the general population and found higher rates of fracture among HIV patients. http://phys.org/news219039261.html Medicine & Health Fri, 11 Mar 2011 04:40:01 EST news219039261 Preliminary research indicates that use of nitroglycerin ointment among postmenopausal women for 2 years was associated with a modest increase in bone mineral density and decrease in bone resorption (loss), according to a study in the February 23 issue of JAMA. http://phys.org/news217615513.html Medicine & Health Tue, 22 Feb 2011 16:45:31 EST news217615513 A hip fracture is not common in a 54-year-old woman, unless she is a 54-year-old breast cancer survivor, according to a new Northwestern Medicine study. Researchers found that a combination of early menopause due to breast cancer treatment and common drugs used to treat breast cancer, could be weakening the bones of breast cancer survivors once they hit middle age, leading to hip fractures. http://phys.org/news215843805.html Medicine & Health Wed, 02 Feb 2011 04:37:12 EST news215843805 Women who have survived childhood cancer should be advised to breastfeed if they can, in order to offset some of the negative health effects of their earlier cancer treatment. According to Susan Ogg and colleagues from St. Jude Children's Research Hospital in Memphis, Tennessee, making women aware of the benefits of breastfeeding should be part of routine post-cancer diet and healthy lifestyle recommendations. Their work is published online in Springer's Journal of Cancer Survivorship. http://phys.org/news214746300.html Medicine & Health Thu, 20 Jan 2011 11:45:20 EST news214746300 An expert working group of the International Osteoporosis Foundation (IOF) and the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) has released a new position paper which reviews the evidence of bone turnover markers (BTMs) in fracture risk prediction and monitoring of osteoporosis therapy. More importantly, it identifies research priorities and recommends that specific markers be used as reference analytes for BTMs in clinical and observational studies. http://phys.org/news212672678.html Medicine & Health Mon, 27 Dec 2010 11:45:12 EST news212672678 For years, it was believed that obese women were at lower risk for developing osteoporosis, and that excess body fat actually protected against bone loss. However, a study presented today at the annual meeting of the Radiological Society of North America (RSNA) found that having too much internal abdominal fat may, in fact, have a damaging effect on bone health. http://phys.org/news210310894.html Medicine & Health Tue, 30 Nov 2010 03:45:41 EST news210310894 Older adults with even mildly decreased levels of sodium in the blood (hyponatremia) experience increased rates of fractures and falls, according to a study presented at the American Society of Nephrology's 43rd Annual Meeting and Scientific Exposition. Falls are a serious health problem for the elderly and account for about 50 percent of deaths due to injury in the elderly. http://phys.org/news209443720.html Medicine & Health Sat, 20 Nov 2010 03:10:01 EST news209443720 Taking time off from certain osteoporosis drugs may be beneficial to bone health, according to a study conducted at Loyola University Health System. Researchers found that bone density remained stable for three years in patients who took a drug holiday from bisphosphonates, a popular class of osteoporosis drugs that can cause fractures in the thigh bones and tissue decay in the jaw bone. http://phys.org/news209311814.html Medicine & Health Thu, 18 Nov 2010 14:30:01 EST news209311814 A new method for identifying which bones have a high risk of fracture, and for monitoring the effectiveness of new bone-strengthening drugs and techniques, has been developed by scientists at the University of Cambridge. http://phys.org/news207908547.html Medicine & Health Tue, 02 Nov 2010 09:22:44 EST news207908547 Since 2002, the U.S. Preventive Services Task Force has recommended that women ages 65 and older be routinely screened for osteoporosis and has suggested that a 2-year screening interval might be appropriate. However, what length the screening interval should be is a topic that remains controversial and undecided, with no definitive scientific evidence to provide guidance. http://phys.org/news206595253.html Medicine & Health Mon, 18 Oct 2010 04:50:01 EST news206595253 Ultrasound can speed the healing of fractures. A randomized controlled trial reported in the open access journal BMC Musculoskeletal Disorders has found that the use of low-intensity pulsed ultrasound (LIPUS) in patients with tibial fractures which showed inadequate progress toward healing resulted in 34% greater bone mineral density (BMD) in the fracture area after 16 weeks than use of a sham device. http://phys.org/news205730179.html Medicine & Health Fri, 08 Oct 2010 04:16:37 EST news205730179 Health benefits from polyphenol antioxidants -- substances found in many fruits and vegetables -- may come at a cost to some people. Penn State nutritional scientists found that eating certain polyphenols decreased the amount of iron the body absorbs, which can increase the risk of developing an iron deficiency. http://phys.org/news201794074.html Medicine & Health Mon, 23 Aug 2010 15:20:02 EST news201794074 A thesis from the University of Gothenburg (Sweden) is the first in Scandinavia to study the occurrence of low bone mineral density in children and teenagers with inflammatory bowel disease. Half of the patients in the study showed signs of low bone mineral density. The results emphasise the importance of treating the underlying inflammatory bowel disease more effectively, and of measuring bone mineral density in this group of patients. http://phys.org/news201777683.html Medicine & Health Mon, 23 Aug 2010 10:21:40 EST news201777683 A comprehensive Argentinean epidemiological study reveals the staggering costs of osteoporosis in the country. http://phys.org/news198320598.html Medicine & Health Wed, 14 Jul 2010 10:30:01 EST news198320598 Overweight and moderately obese postmenopausal women using diets based on higher protein intake also need to be aware of potential bone loss, according to new research from Purdue University. http://phys.org/news197735443.html Medicine & Health Wed, 07 Jul 2010 15:50:05 EST news197735443 A recent study determined that bone area predicted the development of medial (inner side) and lateral (outer side) knee cartilage damage and loss of medial cartilage volume. Subchondral bone mineral density (BMD) was associated with medial defect development but not cartilage loss. Researchers believe subchondral bone changes and loss of cartilage contribute to the development of osteoarthritis (OA).

When it doesn't, growth hormone is a safe and effective treatment to promote growth, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). http://phys.org/news194806479.html Medicine & Health Thu, 03 Jun 2010 17:54:51 EST news194806479 Individuals treated for acne, psoriasis or another skin condition with vitamin A analogues (retinoids) do not appear to be at increased risk of fracture, according to a report in the May issue of Archives of Dermatology. http://phys.org/news193319586.html Medicine & Health Mon, 17 May 2010 16:00:05 EST news193319586 The recent start of the North American cycling season marks the beginning of a physically demanding time for elite and professional bicycle racers who participate in multi-day stage races. Previous research has found that competitive cyclists have significantly lower bone mineral density (BMD) than other endurance athletes, making them more susceptible to fractures. The reasons for the reduced bone mass in elite cyclists are not fully understood, but one explanation is an imbalance between bone formation and bone breakdown due to the high-energy cost of stage racing. However, a new University of Missouri study reveals that proper nutrition during multi-day stage races might prevent harmful changes in bone turnover. http://phys.org/news192276070.html Medicine & Health Wed, 05 May 2010 11:35:02 EST news192276070 Seniors who consume a higher level of dietary protein are less likely to suffer hip fractures than seniors whose daily dietary protein intake is less, according to a new study by the Institute for Aging Research of Hebrew SeniorLife in Boston, an affiliate of Harvard Medical School. http://phys.org/news192255584.html Medicine & Health Wed, 05 May 2010 05:20:02 EST news192255584 A team of international researchers has identified 20 genes associated with osteoporosis and bone weakness, including 13 genes never previously associated with the disease. Osteoporosis is a highly heritable trait, but this marks the largest international effort to conclusively identify genes linked to the often-devastating bone disorder. http://phys.org/news192112729.html Medicine & Health Mon, 03 May 2010 13:50:01 EST news192112729 The stage for osteoporosis is set well before menopause—but exercise can help rewrite the script, according to Medical College of Georgia researchers. http://phys.org/news191498772.html Medicine & Health Mon, 26 Apr 2010 11:06:30 EST news191498772 Diminished bone density is common among menopausal women and raises their risk of osteoporosis, bone fractures and subsequent complications. Research has traditionally focused on therapies that seek to maintain the level of estrogen in the body. This hormone seems to sustain bone health, but it drops to an extremely low level during and after menopause. http://phys.org/news191417023.html Medicine & Health Sun, 25 Apr 2010 16:00:02 EST news191417023 Increasing calcium intake is a common -- yet not always successful -- strategy for reducing bone fractures. But a study supported in part by the Agricultural Research Service (ARS) underscores the importance of vitamin D and its ability to help the body utilize calcium. The study also may explain why increasing calcium alone isn't always successful in dealing with this problem. http://phys.org/news187608414.html Medicine & Health Fri, 12 Mar 2010 09:40:03 EST news187608414 The observed improvements in bone mineral density, strength and postural balance due to recreational soccer are of particularly interest for a large group of women but also for elderly men, says project leader Associate Professor Peter Krustrup, University of Copenhagen, and continues "It is well known that the risk of falls and fractures increases with age as a result of weaker bones, poorer balance and attenuated ability to trigger rapid muscle force, but the present results suggest that soccer - and possibly other ball games - is an effective training method to reduce bone weakening that comes with increasing age". http://phys.org/news186832695.html Medicine & Health Wed, 03 Mar 2010 09:58:30 EST news186832695 The old advertising slogan that "Guinness is Good for You" may have some truth to it after all. Every pint of the black stuff contains as much silicon as a pinch of sand -- and that silicon, according to recent but controversial research, may help to keep your bones strong in old age. http://phys.org/news185089110.html Medicine & Health Thu, 11 Feb 2010 05:50:01 EST news185089110 A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. Researchers from the Department of Food Science & Technology at the University of California, Davis studied commercial beer production to determine the relationship between beer production methods and the resulting silicon content, concluding that beer is a rich source of dietary silicon. Details of this study are available in the February issue of the Journal of the Science of Food and Agriculture, published by Wiley-Blackwell on behalf of the Society of Chemical Industry. http://phys.org/news184827223.html Chemistry Mon, 08 Feb 2010 04:53:58 EST news184827223 The maximum time an athlete is able to continue climbing to exhaustion may be the only determinant of his/her performance.
