Patients with metabolic disorder may face higher complication risk following total joint replacement

Patients who are overweight, with hypertension, most at risk

2014-03-11

(Press-News.org) NEW ORLEANS─In a new study presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers found that total joint replacement patients with three or more metabolic syndrome risk factors were almost three times as likely to have complications within the first year after joint replacement.

Metabolic syndrome is a combination of disorders, such as obesity with a body mass index (BMI) ≥30kg/m², dyslipidemia (an abnormal amount of lipids in the blood), hypertension and diabetes. An estimated 47 million adults, ages 20 and older, and one million adolescents in the U.S. have this syndrome which increases the risk of cardiovascular disease.

The study, "Impact of Metabolic Syndrome on Peri-Operative Complication Rates after Total Joint Replacement Surgery," included 168 patients with characteristics of metabolic syndrome who underwent total hip and total knee replacements. Of the 39 patients with three or more risk factors, only 21 (16.3 percent) had complications within the first year. Obesity, measured by BMI, had the biggest impact on postoperative complications, with complications occurring in 16.2 percent of the patients with a BMI greater than 30 kg/m2. For patients with BMI below 30 kg/m2, risk for complications was only 1.6 percent. The impact of BMI becomes even greater when combined with hypertension: 30.8 percent of patients with a BMI≥30kg/m2 and hypertension experienced complications.

Identifying, counseling and addressing these issues in patients with metabolic syndrome risk factors could reduce complication rates, according to the study authors.

Study finds no greater injury risk on artificial playing surfaces

2014-03-11

NEW ORLEANS─New research presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found no greater injury risk for athletes playing on artificial playing surfaces. The use of artificial playing surfaces at sport venues has increased significantly in recent years, primarily due to the advantages of artificial turf over natural grass: longer playing hours, lower maintenance costs and greater resilience to harsh weather conditions. Despite these advantages, many elite professional soccer teams are reluctant to install artificial ...

Major League Baseball players win more games following Tommy John surgery

2014-03-11

NEW ORLEANS─Ulnar collateral ligament (UCLR) reconstruction, otherwise known as "Tommy John Surgery," is a procedure frequently performed on Major League Baseball (MLB) pitchers with a damaged or torn ulnar collateral ligament, a common elbow injury, typically from overuse. In the new study, "Rate of Return to Pitching and Performance after Tommy John Surgery in Major League Baseball Pitchers," * presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers looked at the rate of return to MLB pitching following UCLR, ...

Total hip replacement surgery safe for nonagenarian patients

2014-03-11

NEW ORLEANS--As more Americans are living well into their 90s, the number of nonagenarian total hip replacement (THR) candidates continues to increase. In the study, "Total Hip Arthroplasty Proves Safe for Nonagenarian Patients," presented today at the at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), researchers reviewed patient characteristics and rates of postoperative morbidity, mortality and readmission among patients who underwent elective THR surgery between April 2001 and December 2011. Of the 43,543 THRs performed during this ...

Genetics may explain high-functioning senior athletes with hip abnormalities

2014-03-11

NEW ORLEANS─Genetics may explain why some senior athletes are high functioning despite having one or both hip abnormalities typically associated with early onset osteoarthritis (OA): developmental dislocation of the hip (dysplasia), a loose hip joint; or femoroacetabular impingement (FAI), a condition in which the hip bones are abnormally shaped, according to new research presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). In the study, "Prevalence of Radiographic Abnormalities in Senior Athletes with Well-functioning ...

Clinical trial identifies women most likely to benefit from vaginal mesh surgery

2014-03-11

Certain women with vaginal prolapse are most likely to benefit from undergoing vaginal mesh surgery, a technique that has become controversial and is the focus of numerous lawsuits. The findings, which are published early online in Ultrasound in Obstetrics & Gynecology, provide valuable information regarding who should and should not be considered candidates for the surgery. Vaginal prolapse—when pelvic tissues weaken and the vaginal canal may protrude through the vaginal opening—affects roughly 10% to 20% of women. A significant number of patients require repeat surgeries ...

Healthy food is good for you -- and can sell, too

2014-03-11

In the fall of 2008, the booster club in Muscatine, Iowa took a chance. Researchers from the University of Iowa asked whether the club would add healthy foods – from apples to string cheese – to its concessions menu. And, by the way, would it also consider putting healthier ingredients in big sellers like nachos and popcorn? These were no idle requests. Booster clubs across the United States directly support schools' athletic and extra-curricular programs like band and choir. The Muskie Boosters, for instance, raise $90,000 annually for athletics and other outside school ...

Light pollution impairs rainforest regeneration

2014-03-11

These new findings were reported by scientists from the German Leibniz Institute for Zoo and Wildlife Research Berlin (IZW). The study – published in the British Ecological Society's Journal of Applied Ecology – is the first to show that seed-dispersing bats avoid feeding in light-polluted areas. Working in Costa Rica with Sowell's short-tailed bats (Carollia sowelli), Daniel Lewanzik from the IZW gave the bats a simple choice. He divided a flight cage into two compartments. One was naturally dark and the other was illuminated by a sodium street lamp, the most common ...

Glucosamine fails to prevent deterioration of knee cartilage, decrease pain

2014-03-11

A short-term study found that oral glucosamine supplementation is not associated with a lessening of knee cartilage deterioration among individuals with chronic knee pain. Findings published in Arthritis & Rheumatology, a journal of the American College of Rheumatology (ACR) journal, indicate that glucosamine does not decrease pain or improve knee bone marrow lesions—more commonly known as bone bruises and thought to be a source of pain in those with osteoarthritis (OA). According to the ACR 27 million Americans over 25 years of age are diagnosed with OA—the most common ...

Speed trap for fish catches domestic trout moving too slow

2014-03-11

PULLMAN, Wash.—Washington State University researchers have documented dramatic differences in the swimming ability of domesticated trout and their wilder relatives. The study calls into question the ability of hatcheries to mitigate more than a century of disturbances to wild fish populations. Kristy Bellinger, who did the study for her work on a Ph.D. in zoology, said traditional hatcheries commonly breed for large fish at the cost of the speed they need to escape predators in the wild. "The use of hatcheries to support declining wild salmon and steelhead is controversial," ...

Prescriptions for opioids stabilizing after fivefold increase in 10-year span

2014-03-11

March 10, 2014 -- Death rates from opioids have been soaring in the U.S. since the 1990s. To support the appropriate use of these controlled substances and inform public health interventions to prevent drug abuse, most states have implemented a prescription drug monitoring program (PDMP). In a latest study, researchers at Columbia University's Mailman School of Public Health evaluated the impact of these state-wide programs and found that after tripling until 2007, annual rates of prescriptions for opioid analgesics have stabilized although the effects of PDMPs on opioid ...
