SAN FRANCISCO – Patients who have had total joint replacement (TJR) are expected to return to their physician's office or clinic regularly for routine follow-up care. In a new study presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers asked 210 TKR patients (with no known complications) to either complete a Web-based follow-up, which included an online survey and an X-ray taken at the nearest Internet-enabled facility; or, to return to the clinic/office for their regular appointment.

AKRON, Ohio, February 8, 2012 – A new community-wide collaboration to reduce the impact of chronic disease and empower patients is generating impressive early results, leaders of the Accountable Care Community (ACC) initiative said today. The Akron-based Austen BioInnovation Institute in Akron (ABIA) is leading the initiative with its founding institutional members and more than 60 public and private community partners.

SAN FRANCISCO – In hip resurfacing the femoral ball in the hip joint is not removed, but instead is trimmed and capped with a smooth metal covering. Young and active patients with arthritis often choose hip resurfacing over total hip replacement to minimize the risk of hip dislocation, and to preserve the bone for a revision surgery should the primary resurfacing fail. However, the long-term effects of sports on a resurfaced hip were unknown.

Fingerprints, ballistics, DNA analysis and other mainstays of the forensic science toolkit may get a powerful new crime-solving companion as scientists strive to develop technology for "fingerprinting" and tracing the origins of chemical substances that could be used in terrorist attacks and other criminal acts. That's the topic of the cover story in the current issue of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.

Washington D.C., February 8, 2012 – Attention-deficit/hyperactivity disorder (ADHD) affects 5-9% of youth and is frequently treated with stimulant medications, such as methylphenidate and amphetamine products. A recent safety communication from the US Food and Drug Administration advised that all patients undergoing ADHD treatment be monitored for changes in heart rate or blood pressure.

Potentially key fingerprint evidence is currently not being considered due to shortcomings in the way it is reported, according to a report published today in Significance, the magazine of the Royal Statistical Society and the American Statistical Association. Researchers involved in the study have devised a statistical model to enable the weight of fingerprint evidence to be quantified, paving the way for its full inclusion in the criminal identification process.

SAN FRANCISCO – The benefits of exercise in minimizing pain and improving mobility for individuals living with osteoarthritis has been well documented.

SAN FRANCISCO —There is growing evidence that supports an association between atypical fractures of the femur– a rare break of the thigh bone, typically without trauma – and the use of bisphosphonates, drugs proven to enhance bone density and reduce fracture incidence caused by osteoporosis.

A new study has demonstrated that a procedure wherein healthy cartilage is transplanted to fix an area of damaged cartilage (osteoarticular cartilage transplantation or OATS procedure) is superior to the standard of care for repairing cartilage defects. It is thought that fixing such lesions may ultimately help to prevent the onset of osteoarthritis, and get athletic individuals back to sporting activities reliably. The study by Hospital for Special Surgery researchers was reported at the annual meeting of the American Academy of Orthopaedic Surgeons, Feb. 7-11.

In low- and middle-income countries, mild cognitive impairment—an intermediate state between normal signs of cognitive aging, such as becoming increasingly forgetful, and dementia, which may or may not progress—is consistently associated with higher disability and with neuropsychiatric symptoms but not with most socio-demographic factors, according to a large study published in this week's PLoS Medicine.

SAN FRANCISCO – Previous studies have found that human behavior during a recession is remarkably different than that during a bullish economy. For example, people tend to spend more time focused on working and less time engaging in leisure and recreation activities, resulting in fewer motor vehicle and other accidents.

According to a 10-year study at a Level 1 regional trauma center, presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), economic trends do impact orthopedic trauma volume.

SAN FRANCISCO – Wrist fractures, also called distal radius fractures (DRF), are among the most common osteoporosis-related fractures occurring on average 15 years earlier than hip fractures. As vitamin D deficiency has recently been linked with muscle weakness, increased fall risks, and bone fractures, investigators sought to determine the prevalence of vitamin D deficiency among post menopausal women with DRF.

(PHILADELPHIA) – Researchers at the Rothman Institute at Jefferson examined data on patients being treated for lumbar stenosis and the degenerative spine condition spondylolisthesis and found that patients who received epidural steroid injections (ESI) had a higher rate of crossover to surgery and fared worse in physical health and bodily pain versus those who did not receive ESI, dispelling their pre-study hypothesis.

How can insurers justify spending hundreds of thousands of dollars per patient per year on "orphan drugs" – extremely expensive medications for rare conditions that are mostly chronic and life-threatening -- when this money could provide greater overall health benefit if spread out among many other patients? Those spending decisions reflect the "rule of rescue," the value that our society places on saving lives in immediate danger at any expense.

SAN FRANCISCO -- Poor emotional health and morbid obesity are associated with less functional gain following total knee replacement (TKR) surgery. In the new study, "Can Telephone Support During Post-TKR Rehabilitation Improve Post-op Function: A Randomized Controlled Trial," presented today at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), approximately 180 patients were categorized by gender, body mass index (BMI) and emotional health.
