BACKGROUND AND PURPOSE Swallowing dysfunction (dysphagia) is common and disabling after acute stroke, but its impact on long-term prognosis for potential complications and the recovery from swallowing dysfunction remain uncertain. We aimed to prospectively study the prognosis of swallowing function over the first 6 months after acute stroke and to identify(More)
OBJECTIVE To determine whether metformin would safely reduce the rate of first-trimester spontaneous abortion without teratogenicity in 19 women with the polycystic ovary syndrome (PCOS). DESIGN Prospective pilot study. SETTING Outpatient. PATIENT(S) Twenty-two previously oligoamenorrheic, nondiabetic women with PCOS; 125 women with PCOS who were not(More)
We prospectively examined 128 patients with acute first-ever stroke to determine the prevalence of swallowing disorders, the diagnostic accuracy of our clinical assessment of swallowing function compared with videofluoroscopy, and interobserver agreement for the clinical and videofluoroscopic diagnosis of swallowing disorders and aspiration. We found(More)
The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton–proton collision data with a centre-ofmass energy of √ s = 7 TeV corresponding to an integrated luminosity of 4.7 fb−1. Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells using the anti-kt(More)
This article documents the performance of the ATLAS muon identification and reconstruction using the LHC dataset recorded at √ s = 13 TeV in 2015. Using a large sample of J/ψ → μμ and Z → μμ decays from 3.2 fb−1 of pp collision data, measurements of the reconstruction efficiency, as well as of the momentum scale and resolution, are presented and compared to(More)
A search for squarks and gluinos in final states containing hadronic jets, missing transverse momentum but no electrons or muons is presented. The data were recorded in 2015 by the ATLAS experiment in √ s = 13 TeV proton–proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 3.2 fb−1 of(More)
The records of the two main referral centres for the western and central Arctic were reviewed for Eskimo patients with cancer diagnosed between 1949 and 1974 inclusive. To these were added the records for the past 6 years of patients from the eastern Arctic, giving the toatal of 180 histologically proved cases of malignant disease. Athe data were analysed(More)
Pulse oximeters may delay displaying the correct oxygen saturation during the onset of hypoxia. We investigated the desaturation response times of pulse oximeter sensors (forehead, ear and finger) during vasoconstriction due to mild hypothermia and vasodilation caused by glyceryl trinitrate. Ten healthy male volunteers were given three hypoxic challenges of(More)
Protein products of 24 loci from the genomes of Yellowstone Park elk were analyzed by electrophoresis. Heterozygosity was detected in only one system, making elk much less polymorphic than eastern whitetailed deer. Data for several other large mammals are compared with those for elk and reveal similarly low levels of isozymic variation. The data are(More)
