A new study shows the prevalence of gout in the U.S. has risen over the last twenty years and now affects 8.3 million (4%) Americans. Prevalence of increased uric acid levels (hyperuricemia) also rose, affecting 43.3 million (21%) adults in the U.S. Greater frequency of obesity and hypertension may be associated with the jump in prevalence rates according to the findings now available in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR).
Gout, an inflammatory arthritis triggered by crystallization of uric acid within the joints, causes severe pain and swelling. Medical evidence suggests that gout is strongly associated with metabolic syndrome—a group of health conditions characterized by central obesity, insulin resistance, high blood pressure and blood lipid issues—and may lead to heart attack, diabetes and premature death. Prior research found that gout incidence in the U.S. more than doubled from the 1960s to 1990s.
"Our study aim was to determine if the prevalence of gout and hyperuricemia among U.S. adults has continued to climb in the new millennium," said Dr. Hyon Choi, Professor of Medicine in the Section of Rheumatology and the Clinical Epidemiology Unit at Boston University School of Medicine in Massachusetts and senior investigator of the present study.
Researchers analyzed data from the latest U.S. National Health and Nutrition Examination Survey (NHANES) which was conducted in 2007 and 2008, comparing the data with those from previous NHANES surveys (1988-1994). There were 5,707 participants who completed the most recent NHANES survey which included questions regarding history of gout diagnosed by a healthcare professional. Researchers defined hyperuricemia as serum urate level greater than 7.0 mg/dL in men and 5.7 mg/dL in women.
Results from the nationally-representative sample of adult Americans suggest gout and hyperuricemia remain prevalent in the U.S. and compared to earlier NHANES data was 1% and 3% higher, respectively. After adjusting for obesity or hypertension, the differences in prevalence rates were substantially lessened. Further analysis revealed that gout prevalence was higher in men (6%) compared to women (2%); hyperuricemia occurred in 21.2% of men and 21.6% of women.
Dr. Choi concluded, "We found that the prevalences of gout and hyperuricemia continue to be substantial in the U.S. adult population. Improvements in managing modifiable risk factors, such as obesity and hypertension, could help prevent further escalation of gout and hyperuricemia among Americans."

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
