An international team of researchers led by Antonio Naranjo of the University of Las Palmas de Gran Canaria, Spain, and colleagues in Argentina, Europe, and the USA have analyzed data from the QUEST-RA (Quantitative Patient Questionnaires in Standard Monitoring of Patients with Rheumatoid Arthritis) study.
From this study, including 4,363 patients from 48 sites in 15 countries, the team has examined the causes and effects of rheumatoid arthritis, as well as the potential benefits of medications.
Rheumatoid arthritis is a known risk factor for hardening of the arteries and so can lead to stroke and heart attacks occurring in sufferers ten years earlier than in people without the condition. However, earlier studies have shown that treating rheumatoid arthritis with disease-modifying anti-rheumatic drugs (DMARDs), such as methotrexate, may reduce this risk. The current research quantifies this risk reduction in thousands of patients in the QUEST-RA study.
Naranjo and colleagues found that risk, when adjusted for age, sex, disease activity, and traditional risk factors such as lack of exercise, smoking, diabetes, and high cholesterol levels, correlated strongly with the use of drugs to treat rheumatoid arthritis. Taking methotrexate – the most widely used DMARD – for just one year for example was found to be associated with an 18% reduction in risk of heart attack and an 11% decrease in risk of stroke, the researchers say.
"Our study provides further support of the influence of both traditional and RA specific risk factors in the development of cardiovascular events, especially heart attack" the researchers conclude, "As assessed by this study, the risk was lower with the prolonged use of methotrexate, sulfasalazine, glucocorticoids, leflunomide and TNF-a blockers."
In an accompanying editorial, Dr Ronald van Vollenhoven of Karolinska Institute, Sweden, reviews the research article. “The possibility that antirheumatic therapy decreases the risk for cardiovascular complications is tantalizing," writes the author. "The current study, while not exactly proving this point, adds a further measure of support to the concept, and suggests that it must now be formally addressed.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
