Early imaging for back pain in older adults not associated with better outcomes

2015-03-17
(Press-News.org) Older adults who had spine imaging within 6 weeks of a new primary care visit for back pain had pain and disability over the following year that was not different from similar patients who did not undergo early imaging, according to a study in the March 17 issue of JAMA.

When to image older adults with back pain remains controversial. Many guidelines recommend that older adults undergo early imaging because of the higher prevalence of serious underlying conditions. However, there is not strong evidence to support this recommendation. Adverse consequences of early imaging are more substantial in an older population because the prevalence of incidental findings on spine imaging increases with age, which may lead to a cascade of subsequent interventions that increase costs without benefits, according to background information in the article.

Jeffrey G. Jarvik, M.D., M.P.H., of the University of Washington, Seattle, and colleagues compared function and pain at the 12-month follow-up visit among older adults who received early imaging (within 6 weeks) with those who did not. The study included 5,239 patients (65 years or older) with a new primary care visit for back pain in three U.S. health care systems, who did not have radiculopathy (a condition affecting the spinal nerve roots and spinal nerves). Diagnostic imaging (plain films, computed tomography [CT], magnetic resonance imaging [MRI]) was of the lumbar or thoracic spine.

Among the patients studied, 1,174 had early radiographs and 349 had early MRI/CT. At 12 months, neither the early radiograph group nor the early MRI/CT group differed significantly from controls on measures of back or leg pain-related disability.

In contrast, there were marked differences in 1-year resource use and costs. Estimated monetary differences in 1-year total payments (payer and patient contributions) were $1,380 higher for patients with early radiographs and $1,430 higher for patients with early MRI/CTs.

"Among older adults with a new primary care visit for back pain, early imaging was not associated with better 1-year outcomes. The value of early diagnostic imaging in older adults for back pain without radiculopathy is uncertain."

Duration of antiplatelet therapy following PCI, risk of adverse events

2015-03-17
An additional 18 months of dual antiplatelet therapy among patients who received a bare metal coronary stent did not result in significant differences in rates of stent thrombosis (formation of a blood clot), major adverse cardiac and cerebrovascular events, or moderate or severe bleeding, compared to patients who received placebo, according to a study in the March 17 issue of JAMA. The authors note that limitations in sample size may make definitive conclusions regarding these findings difficult. Current clinical practice guidelines recommend a minimum of only 1 month ...

Study raises concerns about reporting of noninferiority trials

2015-03-17
An examination of the reporting of noninferiority clinical trials raises questions about the adequacy of their registration and results reporting within publicly accessible trial registries, according to a study in the March 17 issue of JAMA. Noninferiority clinical trials are designed to determine whether an intervention is not inferior to a comparator by more than a prespecified difference (known as the noninferiority margin). Selection of an appropriate margin is fundamental to noninferiority trial validity, yet a point of frequent ambiguity. Given the increasing ...

Winter hack: Textured rubber that grips slick, icy surfaces

Winter hack: Textured rubber that grips slick, icy surfaces
2015-03-17
WASHINGTON, D.C., March 17, 2015 - Winter storms dumped records amounts of snow on the East Coast and other regions of the country this February, leaving treacherous, icy sidewalks and roads in their wake. Now researchers from Canada are developing new methods to mass-produce a material that may help pedestrians get a better grip on slippery surfaces after such storms. The material, which is made up of glass fibers embedded in a compliant rubber, could one day be used in the soles of slip-resistant winter boots. The researchers describe the manufacturing process in a ...

Teens' approach to social media risk is different from adults'

2015-03-17
For every parent who ever wondered what the heck their teens were thinking when they posted risky information or pictures on social media, a team of Penn State researchers suggests that they were not really thinking at all, or at least were not thinking like most adults do. In a study, the researchers report that the way teens learn how to manage privacy risk online is much different than how adults approach privacy management. While most adults think first and then ask questions, teens tend to take the risk and then seek help, said Haiyan Jia, post-doctoral scholar in ...

West Coast waters shifting to lower-productivity regime, new NOAA report finds
2015-03-17
Large-scale climate patterns that affect the Pacific Ocean indicate that waters off the West Coast have shifted toward warmer, less productive conditions that may affect marine species from seabirds to salmon, according to the 2015 State of the California Current Report delivered to the Pacific Fishery Management Council. The report by NOAA Fisheries' Northwest Fisheries Science Center and Southwest Fisheries Science Center assesses productivity in the California Current from Washington south to California. The report examines environmental, biological and socio-economic ...

New cystic fibrosis research takes aim at deadly pathogen

2015-03-17
AUSTIN, Texas - A new method of testing the most common cause of life-threatening infection in people with cystic fibrosis could improve efforts to study and combat the illness. The bacterium Pseudomonas aeruginosa is a leading contributor to hospitalizations, serious illness and early death for people with cystic fibrosis (CF). Scientists at The University of Texas at Austin have found a way to re-create conditions specific to the environment in which the bacterium spreads in the lungs of a person with CF, allowing them to identify several genes that appear to be necessary ...

RapidScat eyes Ex-Tropical Cyclone Pam's winds near Chatham Islands

RapidScat eyes Ex-Tropical Cyclone Pams winds near Chatham Islands
2015-03-17
The New Zealand Meteorological Service issued a Storm Warning for the Chatham Islands today as NASA's RapidScat instrument found that winds in one quadrant of Ex-Tropical Cyclone Pam is still generating tropical-storm-force winds east of its center. The International Space Station's RapidScat instrument captured data on Ex-Tropical Cyclone Pam's winds on March 16 from 08:30 to 11:36 UTC. RapidScat revealed sustained winds over 30 meters per second (108 kph/67 mph) were still occurring southeast of the center. The forecast calls for southwesterly winds to 50 knots (57 ...

Genetic markers play role in who benefits from aspirin, NSAIDs to lower colon cancer risk

2015-03-17
INDIANAPOLIS - An Indiana University cancer researcher and her colleagues have identified genetic markers that may help determine who benefits from regular use of aspirin and other nonsteroidal anti-inflammatory drugs for lowering one's risk of developing colorectal cancer. Previous studies have shown that regular use of aspirin and NSAIDs lower one's risk of colorectal cancer, but their use is not recommended as a way to prevent the disease because of uncertainty about the risks and benefits. Thus, the researchers set out to examine the interrelationship between genetic ...

Invasive alien species cause a wide variety of problems, including issues related to conservation; to human and animal health; to agriculture and to fisheries management. But how can science be useful to ...

Chronic bowel inflammation is diagnosed too late in children and adolescents

2015-03-17
Cramping abdominal pains, diarrhea, bloody stools--these are common symptoms of chronic inflammatory bowel disease. Every year, up to 1470 children and adolescents in Germany develop the disease. But chronic inflammatory bowel disease is mostly diagnosed too late in these patients, as Stephan Buderus, Dietmar Scholz, and colleagues show in an original article in the current issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2015; 112: 121-7). The average delay between initial symptoms and diagnosis is four to six months. In most cases, the inflammation ...
