Efficacy and tolerability of abatacept treatment: results of 12 months observation
Objectives: This article reports 1-year clinical outcomes of patients with rheumatoid arthritis (RA) receiving abatacept (ABA) therapy. Materials and methods: Patients (n=91) with high RA activity (DAS28 = 5.1 ± 1.0) and an inadequate response on synthetic DMARDs (mainly methotrexate, 70.3%) and biologics (mainly TNF-α inhibitors, 93%) were included in the study. The majority of patients were middle-aged (49 ± 13.5) womens, RF (72.5%) and ACPA (77%) positive, with moderate functional impairment - HAQ = 1.4 (0.9-2). ABA were administered IV, 10 mg/kg according to the standard scheme. The evaluation of the effectiveness of the therapy was carried out according to the EULAR / ACR 2011 criteria using SDAI, CDAI, HAQ and the intention to treat approach. Results: ABA led to a significant (
STUDY OF THE PARAMETERS OF TOLERABILITY AND ADHERENCE TO THERAPY IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE AND ARTERIAL HYPERTENSION ON THE BACKGROUND OF TREATMENT WITH FIXED COMBINATION OF RAMIPRIL AND AMLODIPINE (ACCORDING TO THE RESULTS OF OBSERVATIONAL STUDY "GRANAT-2")
Working group of the “GRANAT-2” study: Tula - Trubitsyn G.I., Ivanov Yu.V., Mirenkova O.K., Eskova R.A., Simonova R.P., Milon M.E., Telegina E.V., Kuznetsov A.M., Zhukova N.A., Zainullina I.K.; Rostov-on-Don - Budanov O.V., London E.M., Minosyan L.V., Nedashkovskaya N.G., Ter-Ananyants Ye.A.; Tomsk - Proskokova I.Yu., Permyakova O.V., Politova L.V., Maneeva I.D., Ivanova S.Yu.; Nizhny Novgorod - Larina O.V., Pokrovskaya I.N., Patselt E.A.; Moscow - Sladkova T.A., Zelenova Т.V. Aim. To study the tolerability and adherence to antihypertensive therapy in patients with hypertension and chronic obstructive pulmonary disease (COPD) using the fixed combination of ramipril and amlodipine in the observational program for patients with arterial hypertension and COPD (GRANAT-2). Material and methods. Patients with hypertension and COPD (n=52) with all inclusion criteria and without exclusion criteria who signed informed consent to participate in the GRANAT-2 program were included into the study. The use of a fixed combination of ramipril and amlodipine was recommended in all patients. The doses were determined by the treating physicians in accordance with the official drug instruction. The patients had 4 visits, and the duration of the study was 5 months. The Morisky-Green test was used to assess an adherence of patients to treatment. Assessments of blood pressure, adverse events were performed at all visits. Results. 50 of 52 patients completed the study: 45 patients used the studied fixed combination in the recommended doses, and 5 patients used other antihypertensive drugs, 2 patients withdrew from the study. Systolic blood pressure after 1 month of treatment decreased by an average of 20 mm Hg from the baseline, and diastolic blood pressure – by 10 mmHg. These rates after 5 months of therapy were 29 mm Hg and 15 mm Hg, respectively. Target blood pressure level was achieved in all patients. Increase in adherence of patients to treatment (according to the Morisky-Green test from 21.1% to 65.1%) was found. 2 cases of adverse events (dry cough) were registered. The discrepancy in adherence assessment was revealed between the results from the Morisky-Green test and the data from program case report forms. Conclusion. Regular patient visits to the doctor and the rapid achievement of an antihypertensive effect with good tolerability of a fixed combination of ramipril and amlodipine contributed to the increase in adherence of patients to treatment. Undesirable effects of the drug therapy are significant, but not leading factors that have a negative impact on the patient adherence to treatment
Measurement of neutral current e+/-p cross sections at high Bjorken x with the ZEUS detector
The neutral current e+/-p cross section has been measured up to values of
Bjorken x of approximately 1 with the ZEUS detector at HERA using an integrated
luminosity of 187 inv. pb of e-p and 142 inv. pb of e+p collisions at sqrt(s) =
318GeV. Differential cross sections in x and Q2, the exchanged boson
virtuality, are presented for Q2 geq 725GeV2. An improved reconstruction method
and greatly increased amount of data allows a finer binning in the high-x
region of the neutral current cross section and leads to a measurement with
much improved precision compared to a similar earlier analysis. The
measurements are compared to Standard Model expectations based on a variety of
recent parton distribution functions.Comment: 39 pages, 9 figure
Measurement of the cross-section ratio sigma_{psi(2S)}/sigma_{J/psi(1S)} in deep inelastic exclusive ep scattering at HERA
The exclusive deep inelastic electroproduction of and
at an centre-of-mass energy of 317 GeV has been studied with the ZEUS
detector at HERA in the kinematic range GeV,
GeV and GeV, where is the photon virtuality, is the
photon-proton centre-of-mass energy and is the squared four-momentum
transfer at the proton vertex. The data for GeV were taken in
the HERA I running period and correspond to an integrated luminosity of 114
pb. The data for GeV are from both HERA I and HERA II
periods and correspond to an integrated luminosity of 468 pb. The decay
modes analysed were and for the

has been measured as a function of

models of exclusive vector-meson production.Comment: 24 pages, 8 figure
High-E_T dijet photoproduction at HERA
The cross section for high-E_T dijet production in photoproduction has been
measured with the ZEUS detector at HERA using an integrated luminosity of 81.8
pb-1. The events were required to have a virtuality of the incoming photon,
Q^2, of less than 1 GeV^2 and a photon-proton centre-of-mass energy in the
range 142 < W < 293 GeV. Events were selected if at least two jets satisfied
the transverse-energy requirements of E_T(jet1) > 20 GeV and E_T(jet2) > 15 GeV
and pseudorapidity requirements of -1 < eta(jet1,2) < 3, with at least one of
the jets satisfying -1 < eta(jet) < 2.5. The measurements show sensitivity to
the parton distributions in the photon and proton and effects beyond
next-to-leading order in QCD. Hence these data can be used to constrain further
the parton densities in the proton and photon.Comment: 36 pages, 13 figures, 20 tables, including minor revisions from

Combined QCD and electroweak analysis of HERA data
A simultaneous fit of parton distribution functions (PDFs) and electroweak
parameters to HERA data on deep inelastic scattering is presented. The input
data are the neutral current and charged current inclusive cross sections which
were previously used in the QCD analysis leading to the HERAPDF2.0 PDFs. In
addition, the polarisation of the electron beam was taken into account for the
ZEUS data recorded between 2004 and 2007. Results on the vector and
axial-vector couplings of the Z boson to u- and d-type quarks, on the value of
the electroweak mixing angle and the mass of the W boson are presented. The
values obtained for the electroweak parameters are in agreement with Standard
Model predictions.Comment: 32 pages, 10 figures, accepted by Phys. Rev. D. Small corrections

Limits on the effective quark radius from inclusive scattering at HERA
The high-precision HERA data allows searches up to TeV scales for Beyond the
Standard Model contributions to electron-quark scattering. Combined
measurements of the inclusive deep inelastic cross sections in neutral and
charged current scattering corresponding to a luminosity of around 1
fb have been used in this analysis. A new approach to the beyond the
Standard Model analysis of the inclusive data is presented; simultaneous
fits of parton distribution functions together with contributions of "new
physics" processes were performed. Results are presented considering a finite
radius of quarks within the quark form-factor model. The resulting 95% C.L.
upper limit on the effective quark radius is cm.Comment: 10 pages, 4 figures, accepted by Phys. Lett.
