    Adherence to disease-modifying anti-inflammatory rheumatic drugs (DMARDs) in rheumatoid arthritis (RA) patients in Russia and its influence on clinical outcomes have not been studied. The aim of this study was to assess the adherence to DMARDs in rheumatoid arthritis patients. Methods. In cross-sectional study 200 RA patients were interviewed, and their records were analyzed. Inclusion criterion was the duration of follow-up more than a year (mean duration of the disease was 9,2 years). All patients were studied in a tertiary center, and all of them were advised to take different DMARDs. Demographic characteristics and clinical features were assessed, as well as knowledge of patients about RA. Patients were considered to be adherent if they took DMARDs more than 80% of time. Results. 22,5% of RA patients were adherent. The adherence did not influence on clinical features of active inflammation, but it was associated to a less degree of joint destruction: OR=0,32 (95%CI: 0,15-0,67), p=0,003. The main determinants of non- adherence were adverse events of DMARDs, the duration of the disease and the opinion of the patient on the effectiveness of the drug. Conclusion. The adherence to DMARDs in RA patients is low, and it has influence on clinical outcomes.ΠŸΡ€ΠΈΠ²Π΅Ρ€ΠΆΠ΅Π½Π½ΠΎΡΡ‚ΡŒ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… Ρ€Π΅Π²ΠΌΠ°Ρ‚ΠΎΠΈΠ΄Π½Ρ‹ΠΌ Π°Ρ€Ρ‚Ρ€ΠΈΡ‚ΠΎΠΌ (РА) Ρ€Π΅ΠΊΠΎΠΌΠ΅Π½Π΄ΡƒΠ΅ΠΌΠΎΠΌΡƒ Π»Π΅Ρ‡Π΅Π½ΠΈΡŽ базисными ΠΏΡ€ΠΎΡ‚ΠΈΠ²ΠΎΠ²ΠΎΡΠΏΠ°Π»ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹ΠΌΠΈ ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚Π°ΠΌΠΈ (Π‘ΠŸΠ’ΠŸ) ΠΈ Π΅Π΅ влияниС Π½Π° исходы заболСвания Ρƒ российских ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ² Π½Π΅ ΠΈΠ·ΡƒΡ‡Π°Π»Π°ΡΡŒ.

    1D Frustrated Ferromagnetic Model with Added Dzyaloshinskii-Moriya Interaction

    Full text link
    The one-dimensional (1D) isotropic frustrated ferromagnetic spin-1/2 model is considered. Classical and quantum effects of adding a Dzyaloshinskii-Moriya (DM) interaction on the ground state of the system is studied using the analytical cluster method and numerical Lanczos technique. Cluster method results, show that the classical ground state magnetic phase diagram consists of only one single phase: "chiral". The quantum corrections are determined by means of the Lanczos method and a rich quantum phase diagram including the gapless Luttinger liquid, the gapped chiral and dimer orders is obtained. Moreover, next nearest neighbors will be entangled by increasing DM interaction and for open chains, end-spins are entangled which shows the long distance entanglement (LDE) feature that can be controlled by DM interaction.Comment: 8 pages, 9 figure

    Estimate of prevalence of chronic widespread pain syndrome and its association with mental status in rural population

    Chronic widespread pain syndrome (CWPS) affects about 10% of adult population and is associated with several chronic conditions, including mental, according to foreign literature. CWPS in Russia is virtually undiagnosed, although the results of a single pilot study allow to conclude that CWPS in prevalent in Russia and is a medical and social problem. Study aim: examine the prevalence of CWPS in rural population of Russia, activity of pain coping strategies and mental status of such patients. Material and methods. Data of 520 respondents aged 25 and older who were randomly chosen by PC from the rural population of Nizhne-Serginsky district of Sverdlovsk region were analyzed. Responded completed questionnaire by themselves comprised of four parts: a) general pain characterictics; b) body manikins to draw pain; c) questionnaires related to subject attitude to pain; d) mental health questionnaires. Results: Prevalence of CWPS was 8,5% (95% Cl: 6,2-11,2). Prevalence increased with age (OR=1,54, 95% Cl: 1,11-2.16), p=0,007. Analysis of levels of mental distress and somatization showed that CWPS respondents had reasonably higher levels of parameters compared to general population (OR=2,3 (95% Cl: 1,2-4,3) for distress and 0R=7,1 (95% Cl: 3,4-14,8) for somatization). Comparison of CWPS subjects and subjects with non-generalized chronic pain showed that CWPS group has higher intensity of both active pain coping (19,4 vs 17,1, p=0,03) and passive pain coping (33,1 vs 29,5, p=0,005). Conclusion. CWPS in rural population is prevalent and is associated with higher levels of somatization and distress, and high intensity of pain-coping behavior that suggests active seeking of medical and social support. CWPS screening is simple but allows decreasing burden of CWPS on rural healthcare system.Π‘ΠΈΠ½Π΄Ρ€ΠΎΠΌ хроничСской Π³Π΅Π½Π΅Ρ€Π°Π»ΠΈΠ·ΠΎΠ²Π°Π½Π½ΠΎΠΉ Π±ΠΎΠ»ΠΈ (Π‘Π₯Π“Π‘) ΠΏΠΎ Π΄Π°Π½Π½Ρ‹ΠΌ Π·Π°Ρ€ΡƒΠ±Π΅ΠΆΠ½ΠΎΠΉ Π»ΠΈΡ‚Π΅Ρ€Π°Ρ‚ΡƒΡ€Ρ‹ ΠΏΠΎΡ€Π°ΠΆΠ°Π΅Ρ‚ ΠΎΠΊΠΎΠ»ΠΎ 10% взрослого насСлСния, ΠΈ ассоциирован с рядом хроничСских состояний, Π² Ρ‚ΠΎΠΌ числС психичСских.

    Insects and molluscs of the Late Pleistocene at the Gornovo site (Southern Ural foreland, Russia): New data on palaeoenvironment reconstructions

    Get PDF
    The paper presents new data on the subfossil insects and molluscs, as well a new radiocarbon date for the Gornovo site in the Southern Fore-Urals. As a result, the stratigraphic interpretation of the sediments of the lower part of the first above floodplain terrace of the Belaya River is corrected and they are assigned to the Tabulda Horizon (MIS 3) of the Upper Pleistocene in the regional scheme of the Fore-Urals Quaternary. The malacofauna of the locality is represented by 27 species of terrestrial and freshwater molluscs. The composition of molluscs in the deposits of MIS 3 indicates the succession of deposit accumulation in the river valley from the stage of reservoirs that periodically connecting with the river to the stage of the overgrown oxbow lake. Single occurrence of mollusc shells in the loams of MIS 2 is a result of sharp climate change. New insect material includes 136 species of Coleoptera from 17 families, as well as Heteroptera and Hymenoptera representatives. 29 species of beetles (Carabidae, Histeridae, Scarabaeidae, Elateridae, Tenebrionidae, Chrysomelidae, Brentidae and Curculionidae) are recorded for the Pleistocene for the first time. The insect assemblages from Gornovo site are assigned to periglacial and humid boreal faunal types. The entomofauna of the periglacial type has no analogues in the recent fauna; it corresponds to the deposits assigned to the middle of MIS 3. This entomofauna is characteristic to the MIS 2 and MIS 3 insect assemblages from the south of West Siberian Plain. Based on entomological data, the climate of the middle of MIS 3 of the Southern Fore-Urals is reconstructed as dry and cold, extracontinental, with mean July temperature not exceeding +15 Β°C. Steppe landscapes likely prevailed in open areas and coniferous forests were restricted to river valleys. Beetles from deposits dated to end of MIS 3 are assigned to the fauna of the boreal humid type. These insect assemblages are significantly poorer in diversity than periglacial type assemblages and are represented mainly by near water and forest Coleoptera. Based on these species, meadow and forest landscapes were reconstructed. The reconstructed mean air temperature of July ranged from +16 to +19 Β°C. This suggests a trend towards more mild conditions in the region connected to the climate warming at the end of MIS 3. It is likely that humidification during this period was regional, determined by the proximity of the site to the Southern Urals Mountains. Β© 2021 Elsevier Ltd and INQU

    Indices of the 24-hour blood pressure monitoring in young patients with the neurovascular compression of the medulla oblongata

    Get PDF
    Today the neurovascular contact (NVC) is viewed as a possible pathogenetic factor of the development of arterial hypertension. The interrelation between the pulsatile compression of the medulla and the essential hypertension as well as the antihypertensive effect of surgical correction of NVC in the majority of patients have been reported earlier. The goal of the study is the comparison of the results of the 24- hour blood pressure monitoring in young age patients with and without the neurovascular contact of the medulla. We studied 88 young age patients (MΒ±m: 33.3Β±0.78) having performed24 hour blood pressure monitoring and intracranial MR angiography. NVC has been established in 43 patients (48.8%) on the left side, and in 22 patients (25%) - on the right. In patients with NVC on the left side a statistically significant increase of the systolic pressure (135.0Β±2.0 compared 130.5Β±2.8 mmHg, p=0.05) has been established. No other specific changes in the 24- hour arterial blood pressure monitoring parameters have been found in patients with NVC on either left or right side.Π’ настоящСС врСмя нСйроваскулярный ΠΊΠΎΠ½Ρ‚Π°ΠΊΡ‚ (ΠΠ’Πš) рассматриваСтся ΠΊΠ°ΠΊ Π²ΠΎΠ·ΠΌΠΎΠΆΠ½Ρ‹ΠΉ патогСнСтичСский Ρ„Π°ΠΊΡ‚ΠΎΡ€ развития Π°Ρ€Ρ‚Π΅Ρ€ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ Π³ΠΈΠΏΠ΅Ρ€Ρ‚Π΅Π½Π·ΠΈΠΈ.

    Proof of projective Lichnerowicz conjecture for pseudo-Riemannian metrics with degree of mobility greater than two

    Full text link
    We prove an important partial case of the pseudo-Riemannian version of the projective Lichnerowicz conjecture stating that a complete manifold admitting an essential group of projective transformations is the round sphere (up to a finite cover).Comment: 32 pages, one .eps figure. The version v1 has a misprint in Theorem 1: I forgot to write the assumption that the degree of mobility is greater than two. The versions v3, v4 have only cosmetic changes wrt v
