The article is devoted to the study of factors influencing life satisfaction of teenagers raised in families as well as those raised in orphanages. Both groups are studied with regard to their self-attitude, self-confidence and relationships with significant adults. Sample: 96 teenagers aged between 14 and 16 years (46 of them live in or- phanages). Methods: Self-attitude methodology by S.R. Pantileev, Trust questionnaire by T.P. Skripkina, Child-parent relationships questionnaire by O.A. Karabanova and P.V. Troyanskaya, Life Satisfaction scale by E. Diner. The research proved the level of trust in orphanage-raised teenagers to be considerably lower than that of family-raised teenagers. The way teenagers see their relationships with significant adults also turned out to be fairly different in case of orphanage-raised groups due to their caregivers' authoritarian attitude towards them and lack of empathy and communication. The study also shows that the level of life satisfaction in the orphanage group is significantly below the average and substantially lower than in the group from family-raised teenagers. Positive self-attitude, person’s approval of his/ her intellectual capacities, as well as the caregiver's understanding of his pupil's features, are predictors of life satisfaction in the group of teenagers from orphanages. Concerning the family-raised teenagers, much more factors are involved in maintaining their subjective well-being.

Objective. To determine the level of knowledge of doctors on the rational use of antimicrobial drugs in clinical practice and to compare with data of the previous stage of the study and results obtained from students in a parallel project. Materials and Methods. A multicenter questionnaire survey of practitioners with analysis of results – stage of KANT project (full name of the project – «Physicians’ (Students’) knowledge in antimicrobials usage») conducted in 2020–2023. Results. A total of 336 participants were surveyed in 5 centers (10 Russian regions: Belgorod, Novosibirsk, Rostov, Voronezh, Lipetsk, Sakhalin, Primorsky, Krasnodar, and Krasnoyarsk regions, Republic of Tatarstan). The average level of correct answers (LCA) for the whole questionnaire was 47.5% (taking into account the extended analysis of sub-items questions No. 8 and 9 – 46.8%). Doctors showed the best results in answering questions about the time interval during which the effectiveness of antimicrobial therapy is evaluated (LCA – 84.2%); about choosing the most rational action if antimicrobial therapy (AMT) has a positive clinical effect, but requires a long course of therapy (LCA – 72.6%); selection of rational diagnostic/treatment action in the diagnosis of acute tonsillitis or pharyngitis, in a case where etiologic diagnosis is required (LCA – 63.1%). The worst results were recorded in answering to the following questions: indication of the antimicrobial drug of choice in the treatment of various infections (LCA – 29.1%); the choice of auxiliary drugs in addition to the justified appointment of antimicrobial drugs in the treatment of bacterial infections of the respiratory tract for the entire period of the disease or in certain phases (LCA – 26.6% – 35.1%); indication of a combination of antimicrobial drugs that is irrational to prescribe in clinical practice due to a similar mechanism and/or spectrum of activity against pathogens (LCA – 24.4%). Significant differences were found between centers in a number of questions, between physicians in KANT-III and KANT-IV projects (p < 0.001), and between physicians and students in a parallel project (KANT-IV students, LCA – 42.6%, p < 0.001). Conclusions. An unsatisfactory level of physicians’ knowledge of AMT and choice of adjuvant agents, as well as appropriateness of antimicrobial combination was found. The authors believe there is a need for making more efforts in areas of increasing physicians’ compliance to clinical recommendations, expertise and quality control of pharmacotherapy, recruitment of clinical pharmacologists; to optimize the educational process in universities, to expand the scope and availability of additional educational programs within the system of continuous education, as well as to train physicians in using modern sources of scientific medical information.

Both classical and recent reports suggest a right-hemisphere superiority for color discrimination. Testing highly-trained normal subjects and taking care to eliminate asymmetries from the testing situation, we found no significant differences between left and right hemifields or between upper and lower hemifields. This was the case for both of the cardinal axes of color space. In addition, there was no difference according to whether the discriminanda were delivered to the same or to different hemispheres, and we note that the same number of synapses may lie between the retina and the site of comparison whether or not the stimuli are delivered to the same hemisphere.
