Оказание медицинской помощи пациентам с акне. Результаты экспертизы качества медицинской помощи

Goal. To obtain information on typical errors in medical aid rendered to acne patients in dermatovenerology dispensaries in St. Petersburg in order to develop measures to improve the quality of medical aid rendered to this group of patients. Materials and methods. The authors conducted a special expert examination of 55 patients with acne who received treatment at St. Petersburg dermatovenerology dispensaries in 2013. The quality of medical aid was assessed using the Automated Expert Examination Technique (hereinafter referred to as AEET). Major results. The percentage of cases when medical aid of due quality was rendered to acne patients was 49%. Treatment and diagnostics errors prevailed in the structure of errors in medical aid. Errors in treatment were mainly a wrong combination of drugs, simultaneous administration of external and systemic antibacterial drugs, delayed comedolytic therapy and pathogenically infeasible therapy. Errors in diagnostics included absence of indications of the form and/or severity of acne. The most important error in the collection of information was absence of gynecology examinations for women to determine whether peroral contraceptives were necessary including in case of the administration of isotretinoin. Conclusion. The similarity of errors in medical aid rendered for acne as well as high percentage of errors relating to medical aid rendered to patients demand the development of consistent measures to improve the quality of medical aid rendered to such patients and repeated expert examination using preliminary (prompt) control of the quality of medical aid.Цель. Получение информации о типичных ошибках оказания медицинской помощи пациентам с акне в кожно-венерологических диспансерах (КВД) Санкт-Петербурга для разработки мер, направленных на улучшение качества медицинской помощи (КМП) данной группе пациентов. Материал и методы. Проведена тематическая экспертиза КМП 55 наблюдений пациентов с акне, которые получали лечение в КВД Санкт-Петербурга в 2013 г. Изучение КМП проводилось с применением Автоматизированной технологии экспертизы КМП. Результаты. Доля случаев оказания медицинской помощи надлежащего качества пациентам с акне составляла 49%. В структуре ошибок оказания медицинской помощи преобладали ошибки лечения и диагноза. Ошибки лечения были представлены преимущественно неверным сочетанием препаратов, наиболее часто одномоментным назначением антибактериальных препаратов для наружного и системного применения, поздним назначением комедолитической терапии, а также применением патогенетически необоснованной терапии. Ошибками постановки диагноза считали отсутствие указаний на форму и/или степень тяжести акне, наиболее важными ошибками сбора информации - отсутствие обследования женщин у гинеколога для решения вопроса о необходимости применения комбинированных оральных контрацептивов, в том числе и при назначении изотретиноина. Заключение. Сходство характера ошибок медицинской помощи при акне, а также их высокий удельный вес при оказании медицинской помощи пациентам требуют разработки системных мероприятий по улучшению КМП этим больным и повторной экспертизы с применением индикаторов промежуточного (оперативного) контроля КМП

Quantum-mechanical simulations of interaction of many-electron quantum systems with ionizing laser pulses

We develop parallel program for numerical simulation of the interaction of intense laser pulses with manyelectron atoms on the basis of the time-dependent Kohn-Sham equations. It is shown that the use of modern computer clusters makes it possible to solve these equations for a wide class of atoms in a relatively small time, determined by the parameters of the laser pulse and electronic configuration of the atom. High accuracy of the numerical code is demonstrated on the example of calculating the high-frequency spectrum of electron current excited during ionization of noble gas atoms by few-cycle laser pulse.Розробляється паралельний програмний код для чисельного моделювання взаємодії інтенсивних лазерних імпульсів з багатоелектронними атомами на основі нестаціонарного методу функціонала щільності.

Measurement of the View the tt production cross-section using eμ events with b-tagged jets in pp collisions at √s = 13 TeV with the ATLAS detector

This paper describes a measurement of the inclusive top quark pair production cross-section (σtt¯) with a data sample of 3.2 fb−1 of proton–proton collisions at a centre-of-mass energy of √s = 13 TeV, collected in 2015 by the ATLAS detector at the LHC. This measurement uses events with an opposite-charge electron–muon pair in the final state. Jets containing b-quarks are tagged using an algorithm based on track impact parameters and reconstructed secondary vertices. The numbers of events with exactly one and exactly two b-tagged jets are counted and used to determine simultaneously σtt¯ and the efficiency to reconstruct and b-tag a jet from a top quark decay, thereby minimising the associated systematic uncertainties. The cross-section is measured to be: σtt¯ = 818 ± 8 (stat) ± 27 (syst) ± 19 (lumi) ± 12 (beam) pb, where the four uncertainties arise from data statistics, experimental and theoretical systematic effects, the integrated luminosity and the LHC beam energy, giving a total relative uncertainty of 4.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. A fiducial measurement corresponding to the experimental acceptance of the leptons is also presented

Search for strong gravity in multijet final states produced in pp collisions at √s=13 TeV using the ATLAS detector at the LHC

A search is conducted for new physics in multijet final states using 3.6 inverse femtobarns of data from proton-proton collisions at √s = 13TeV taken at the CERN Large Hadron Collider with the ATLAS detector. Events are selected containing at least three jets with scalar sum of jet transverse momenta (HT) greater than 1TeV. No excess is seen at large HT and limits are presented on new physics: models which produce final states containing at least three jets and having cross sections larger than 1.6 fb with HT > 5.8 TeV are excluded. Limits are also given in terms of new physics models of strong gravity that hypothesize additional space-time dimensions

Search for TeV-scale gravity signatures in high-mass final states with leptons and jets with the ATLAS detector at sqrt [ s ] = 13TeV

A search for physics beyond the Standard Model, in final states with at least one high transverse momentum charged lepton (electron or muon) and two additional high transverse momentum leptons or jets, is performed using 3.2 fb−1 of proton–proton collision data recorded by the ATLAS detector at the Large Hadron Collider in 2015 at √s = 13 TeV. The upper end of the distribution of the scalar sum of the transverse momenta of leptons and jets is sensitive to the production of high-mass objects. No excess of events beyond Standard Model predictions is observed. Exclusion limits are set for models of microscopic black holes with two to six extra dimensions

The performance of the jet trigger for the ATLAS detector during 2011 data taking

The performance of the jet trigger for the ATLAS detector at the LHC during the 2011 data taking period is described. During 2011 the LHC provided proton–proton collisions with a centre-of-mass energy of 7 TeV and heavy ion collisions with a 2.76 TeV per nucleon–nucleon collision energy. The ATLAS trigger is a three level system designed to reduce the rate of events from the 40 MHz nominal maximum bunch crossing rate to the approximate 400 Hz which can be written to offline storage. The ATLAS jet trigger is the primary means for the online selection of events containing jets. Events are accepted by the trigger if they contain one or more jets above some transverse energy threshold. During 2011 data taking the jet trigger was fully efficient for jets with transverse energy above 25 GeV for triggers seeded randomly at Level 1. For triggers which require a jet to be identified at each of the three trigger levels, full efficiency is reached for offline jets with transverse energy above 60 GeV. Jets reconstructed in the final trigger level and corresponding to offline jets with transverse energy greater than 60 GeV, are reconstructed with a resolution in transverse energy with respect to offline jets, of better than 4 % in the central region and better than 2.5 % in the forward direction

Search for dark matter produced in association with a hadronically decaying vector boson in pp collisions at sqrt (s) = 13 TeV with the ATLAS detector

A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 fb−1 of pp collisions at View the MathML sources=13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet compatible with a W or Z boson and with large missing transverse momentum are analysed. The data are consistent with the Standard Model predictions and are interpreted in terms of both an effective field theory and a simplified model containing dark matter

Measurement of the cross section for isolated-photon plus jet production in pp collisions at √s=13 TeV using the ATLAS detector

The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti- algorithm with radius parameter and required to have transverse momenta above 100 GeV. Measurements of isolated-photon plus jet cross sections are presented as functions of the leading-photon transverse energy, the leading-jet transverse momentum, the azimuthal angular separation between the photon and the jet, the photon–jet invariant mass and the scattering angle in the photon–jet centre-of-mass system. Tree-level plus parton-shower predictions from Sherpa and Pythia as well as next-to-leading-order QCD predictions from Jetphox and Sherpa are compared to the measurements

Search for resonances in the mass distribution of jet pairs with one or two jets identified as b-jets in proton–proton collisions at √s=13TeV with the ATLAS detector

Searches for high-mass resonances in the dijet invariant mass spectrum with one or two jets identi-fied as b-jets are performed using an integrated luminosity of 3.2fb−1of proton–proton collisions with a centre-of-mass energy of √s=13TeVrecorded by the ATLAS detector at the Large Hadron Collider. Noevidence of anomalous phenomena is observed in the data, which are used to exclude, at 95%credibility level, excited b∗quarks with masses from 1.1TeVto 2.1TeVand leptophobic Z bosons with masses from 1.1TeVto 1.5TeV. Contributions of a Gaussian signal shape with effective cross sections ranging from approximately 0.4 to 0.001pb are also excluded in the mass range 1.5–5.0TeV
