The spread of depressive disorders is extra high nowadays. Depressive disorders are widespread mental disorders in the structure of mental pathology, both causes of psychiatrists' visit, and causes of medical aid. The presence of depressive syndrome in patients with cardiovascular system leads to deterioration patient's condition and adaptive abilities and aggravates somatic abnormality. Adequate therapy causes their reduction, prevention of recurrence and decompansation of comorbid somatic pathology, and eliminates severe medical and prevents social consequences. The study of clinical aspects of depressive conditions which are accompanied with pathology is one of the direction not only psychiatric, but also common pharmacotherapeutic investigations. The aim of the investigation was to determine clinical, pharmacotherapeutic and biorhythmic peculiarities of depressive disorders in patients with comorbid cardiac pathology. And also assessment of efficacy of complex therapy based on chronotherapy principle was used. 50 patients (female patients) with depressive disorders were involved in this investigation. This was performed based on "Depressive disorders of organic genesis, characterized by somatic pathology" (F 06.35), "Somatoform disorder" of heart and cardiovascular system (F 45.30), "Mild depressive episode" (F 32.00), and also comorbid arterial hypertension confirmed by physician. Clinical, laboratory, clinical and psychopathological investigations using psychodiagnostic scales (scale HAMD-21, CGI-S, CGI-І) were used. Individual biorhythmic status was established and it requires medicamentous therapy. Comparing patients of both groups, it has been detected a group of patients in whom principles of chronotherapy, especially antihypertensive and antidepressive therapy were prescribed, dynamics of patient's improvement was better than in the investigated group where the principle of chronotherapy was observed.

Search for Dark Matter Produced in Association with a Dark Higgs Boson Decaying into W^{±}W^{∓} or ZZ in Fully Hadronic Final States from sqrt[s]=13  TeV pp Collisions Recorded with the ATLAS Detector.

Phys Rev Lett 2021 Mar;126(12):121802

CERN, Geneva, Switzerland.

Several extensions of the Standard Model predict the production of dark matter particles at the LHC. An uncharted signature of dark matter particles produced in association with VV=W^{±}W^{∓} or ZZ pairs from a decay of a dark Higgs boson s is searched for using 139  fb^{-1} of pp collisions recorded by the ATLAS detector at a center-of-mass energy of 13 TeV. The s→V(qq[over ¯])V(qq[over ¯]) decays are reconstructed with a novel technique aimed at resolving the dense topology from boosted VV pairs using jets in the calorimeter and tracking information. Dark Higgs scenarios with m_{s}>160  GeV are excluded.

Longitudinal Flow Decorrelations in Xe+Xe Collisions at sqrt[s_{NN}]=5.44  TeV with the ATLAS Detector.

Phys Rev Lett 2021 Mar;126(12):122301

Department of Physics, Alexandru Ioan Cuza University of Iasi, Iasi, Romania.

The first measurement of longitudinal decorrelations of harmonic flow amplitudes v_{n} for n=2-4 in Xe+Xe collisions at sqrt[s_{NN}]=5.44  TeV is obtained using 3  μb^{-1} of data with the ATLAS detector at the LHC. The decorrelation signal for v_{3} and v_{4} is found to be nearly independent of collision centrality and transverse momentum (p_{T}) requirements on final-state particles, but for v_{2} a strong centrality and p_{T} dependence is seen. When compared with the results from Pb+Pb collisions at sqrt[s_{NN}]=5.02  TeV, the longitudinal decorrelation signal in midcentral Xe+Xe collisions is found to be larger for v_{2}, but smaller for v_{3}. Current hydrodynamic models reproduce the ratios of the v_{n} measured in Xe+Xe collisions to those in Pb+Pb collisions but fail to describe the magnitudes and trends of the ratios of longitudinal flow decorrelations between Xe+Xe and Pb+Pb. The results on the system-size dependence provide new insights and an important lever arm to separate effects of the longitudinal structure of the initial state from other early and late time effects in heavy-ion collisions.

Medium-Induced Modification of Z-Tagged Charged Particle Yields in Pb+Pb Collisions at 5.02 TeV with the ATLAS Detector.

Phys Rev Lett 2021 Feb;126(7):072301

Laboratório de Instrumentação e Física Experimental de Partículas-LIP, Lisboa, Portugal.

The yield of charged particles opposite to a Z boson with large transverse momentum (p_{T}) is measured in 260  pb^{-1} of pp and 1.7  nb^{-1} of Pb+Pb collision data at 5.02 TeV per nucleon pair recorded with the ATLAS detector at the Large Hadron Collider. The Z boson tag is used to select hard-scattered partons with specific kinematics, and to observe how their showers are modified as they propagate through the quark-gluon plasma created in Pb+Pb collisions. Compared with pp collisions, charged-particle yields in Pb+Pb collisions show significant modifications as a function of charged-particle p_{T} in a way that depends on event centrality and Z boson p_{T}. The data are compared with a variety of theoretical calculations and provide new information about the medium-induced energy loss of partons in a p_{T} regime difficult to measure through other channels.

THE RIGHT TO MEDICAL ASSISTANCE FOR DRUG ADDICTS: EXAMINATION OF THE PROBLEM.

Wiad Lek 2020 ;73(12 cz 2):2927-2933

Poltava Law Institute of Yaroslav Mudryi National Law University, Poltava, Ukraine.

Objective: The aim: The purpose of this article is to conduct a thorough review and assessment of the exercise of the right to medical care for drug addicts, in particular in custody, through the analysis of international acts and strategies in the fight against drug addiction, as well as drug policies of individual States.

Patients And Methods: Materials and methods: The study is based on the analysis of international documents, the drug control strategies, the case law of the European Court of Human Rights and analytical researches in this area. The article is based on dialectical, system and structural, comparative and legal methods, the method of analysis and synthesis.

Conclusion: Conclusions: Ensuring human rights without any discrimination should be a priority in the politics of modern States. The implementation of prevention and rehabilitation programs based on scientific evidence is also important. The current situation, in which persons who use drugs experience significant restrictions of their rights and freedoms, is unacceptable.
