Association of restless legs syndrome in type 2 diabetes: a case-control study.

Abstract: RESTLESS LEGS SYNDROME (RLS) IS AN INTRINSIC SLEEP DISORDER IN WHICH PATIENTS DESCRIBE AN URGE TO MOVE THEIR LEGS OR OTHER EXTREMITIES during rest. This may be accompanied by unpleasant sensations that are temporarily relieved by movement. Typically, the sensory-motor complaints of RLS arise or worsen during the night, showing a circadian pattern. RLS discomfort leads to a severe difficulty in initiating and maintaining sleep due to the fact that the motor activity carried out by patients in search of relief prolongs sleep latency and the frequent association of periodic limb movements during sleep causes arousals. Consequently, patients complain of insufficient and unsatisfactory sleep and of altered daytime functioning. Several conditions (such as iron deficiency,1 uremia,2 pregnancy,3 polyneuropathy,4 and rheumatoid arthritis5), which account for about one quarter of the clinical cases, have been associated with RLS, configuring a secondary or symptomatic form. With reference to type 2 diabetes mellitus, there are still no rigorous studies investigating the association between the endocrine disease and RLS.6,7 An association between the 2 disturbances can be suspected, since both clinical conditions show at least 1 possible common pathophysiologic mechanism (polyneuropathy) and diabetic patients are more at risk of presenting RLS than is the general population.8 The aims of this investigation were: (1) to look for an association between RLS and type 2 diabetes in a case-control study, (2) to analyze the characteristics of RLS in diabetic patients, and (3) to identify possible risk factors for the development of RLS in diabetic patients.

On Fractional Laplacians

Abstract: We compare two natural types of fractional Laplacians (− Δ) s , namely, the “Navier” and the “Dirichlet” ones. We show that for 0 < s < 1 their difference is positive definite and positivity preserving. Then we prove the coincidence of the Sobolev constants for these two fractional Laplacians.

Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at √s = 8 TeV with the ATLAS detector

Abstract: The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1 fb(-1) of proton-proton collision data at = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via or , where denotes the lightest neutralino (chargino) in supersymmetric models. The search targets a fully-hadronic final state in events with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits are reported in terms of the top squark and neutralino masses and as a function of the branching fraction of . For a branching fraction of 100%, top squark masses in the range 270-645 GeV are excluded for masses below 30 GeV. For a branching fraction of 50% to either or , and assuming the mass to be twice the mass, top squark masses in the range 250-550 GeV are excluded for masses below 60 GeV.
