A new study, funded by a grant from the National Institute for Arthritis and Musculoskeletal and Skin Diseases (NIAMS), found that two in five adults (42%) with rheumatoid arthritis (RA) were inactive. Taking measures to motivate RA patients to increase their physical activity will improve public health according to the findings now available in Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology (ACR).
The ACR estimates nearly 1.3 million adults in the U.S. are diagnosed with RA, a chronic autoimmune condition characterized by systemic joint inflammation that can damage joints, impair function, and cause significant disability. Until the early 1980s, medical experts recommended medication and rest for those with arthritis. However, current medical evidence now suggests that regular, moderate physical activity benefits arthritis sufferers by maintaining joint flexibility, improving balance, strengthening muscles, and reducing pain.
"While there is much evidence of the benefits of physical activity, RA patients are generally not physically active, and physicians often do not encourage regular physical activity in this patient population," explains Dr. Jungwha Lee, an Assistant Professor in the Department of Preventive Medicine at Northwestern University Feinberg School of Medicine in Chicago, Illinois. "Our study aims to expand understanding of the risk factors associated with inactivity among adults with RA and encourage clinical interventions that promote participation in physical activity."
Dr. Lee and colleagues analyzed data on 176 RA patients, 18 years of age or older enrolled in a randomized controlled trial to assess the effectiveness of an intervention promoting physical activity. The team evaluated pre-intervention data for inactivity which was defined as no sustained 10-minute periods of moderate-to-vigorous physical activity during a week. Researchers also assessed the relationships between inactivity and modifiable risk factors such as motivation for physical activity, obesity, and pain.
Results show that 42% of RA patients were inactive; participating in no moderate-to-vigorous physical activity periods of at least ten minutes during a 7-day period of objective activity monitoring. Researchers found that 53% of study participants lacked strong motivation for physical activity and 49% lacked strong beliefs in the benefits of physical activity. These two modifiable risk factors account for 65% of excess inactivity in this study group.
While previous research relied on self-reported physical activity measures, the strength of the current study lies in the use of accelerometers—a device used to measure acceleration and movement—to objectively assess physical activity in participants. "Physical inactivity among RA patients is a public health concern," concludes Dr. Lee. "Our results suggest that public health initiatives need to address the lack of motivation to exercise and promote the benefits of physical activity to reduce the prevalence of inactivity in those with RA."

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
