RLS is a common yet under-recognized sensory motor disorder characterized by intense, unpleasant leg sensations, and an irresistible urge to move the legs. RLS symptoms can lead to poor sleep and daytime drowsiness. It affects as many as 15 percent of the adult population.
Researchers found that women who reported:
Five to 14 incidences of RLS each month had a 26 percent prevalence of high blood pressure.
More than 15 incidences of RLS had a 33 percent prevalence of high blood pressure.
No RLS symptoms had a 21.4 percent prevalence of high blood pressure.
"If future prospective research confirms this association, then early diagnosis and treatment of RLS might help prevent hypertension," said Salma Batool-Anwar, M.D., M.P.H., the study's first author, and a researcher in the Sleep Medicine Division at Brigham and Women's Hospital and an instructor in medicine at Harvard Medical School in Boston, Mass. "In some cases the treatment of RLS is as simple as prescribing iron supplements, therefore, women who have symptoms suggestive of RLS should talk to their physicians."
In 2005, researchers asked 97,642 women participating in the Nurses Health Study II about their RLS symptoms and hypertension status. More than 80 percent of the participants responded. The average age was 50.4 years.
Specifically, they asked about unusual crawling sensations, or pain combined with motor restlessness and an urge to move. The questions were based on the international restless legs study group criteria.
Researchers found there was a significant relationship between RLS severity and blood pressure, and greater frequency of RLS symptoms was associated with higher concurrent systolic and diastolic blood pressures. This association was independent of other potential covariates such as age, body mass index, smoking status, and presence of stroke or heart attack.
Previous studies in men have suggested a link between frequency of RLS symptoms and the prevalence of high blood pressure.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
