[Complications of flexible ureterorenoscopy: a systematic review].

Retrograde intrarenal surgery (RIRS) is a type of endoscopic intervention on the kidneys performed using a semi-rigid or flexible fiber optic endoscope. RIRS is recommended by national clinical guidelines for stone management sized up to 20 mm. However, like any other surgical intervention, RIRS is associated with the risk of complications.

Response of Fluorescent Boron Difluoride β-Diketonates to X-Rays.

This paper reports the results of a detailed study of the optical response of boron difluoride curcuminoids to radiation exposure. Two lines of the dyes fundamentally different in structure (namely, symmetrical and asymmetrical) were tested. If the absorption responses of their solutions in chloroform to X-rays turns out to be quite close quantitatively (note that it has a very indicative visual manifestation - a gradual discoloration is observed in the dose range up to 300 Gy), the fluorescence ones differ notably: among other things, the former demonstrate much more sensitive reactions (the corresponding limit of detection values ​​differ by up to 2.

[Modern problems of plasma donation services: global experience in solving them].

As an analysis of foreign literature on donation has shown, the global market for therapy with drugs from human plasma is growing, which leads to the need for large volumes. With significant geographic imbalances in the global plasma supply and the dependence of most countries on plasma supplies from the United States, the most vulnerable are low- and middle-income countries, where the challenge of meeting the demand for plasma products requires improvements to regional plasma donation systems. An effective tool for the development of plasma collection services is compliance with the standards of plasma donation services, the development of voluntary free plasma donation, and the optimization of donor recruitment and retention processes.

[A healthy lifestyle of students is a resource for preserving the health of the working-age population in the near future].

The issues of acceptance and support of a healthy lifestyle by various social and age groups of the population, especially among the younger generation and youth, through the pursuit of physical, mental and social well-being remain relevant. Educational organizations, including universities, are important actors in this direction, since their students will soon become leaders in society, decision makers, as well as parents of tomorrow. According to scientists, a weak attitude towards sports, lack of time for physical education lead to a vicious circle of focusing on intellectual education, high knowledge scores, low physical abilities and physical fitness.

[Comprehensive analysis of population mortality by cause: regional features].

Chronic non-communicable diseases (CNCDs) are the main most common causes of death both in the Russian Federation and in the Republic of Tatarstan. Thus, in the traditional structure of mortality in the Republic of Tatarstan in 2022, a "classical triad" is defined: diseases of the circulatory system are in first place (46% of all deaths), neoplasms are in second place (15%), and external causes are in third place.

[To assess the effectiveness of treatment methods for patients of different age groups with basal cell cancer of the skin of the nose and ears].

The relevance of the problems of diagnosis and treatment of skin cancer is currently determined not only by the high incidence rate, but by the existing difficulties in differential diagnosis and treatment with traditional methods. For localizations of basal cell skin cancer (BCSC) that are "inconvenient" for treatment, such as the external auditory canal, auricle, and wing of the nose, treatment is associated with certain difficulties and the possible appearance of a cosmetic defect, therefore, when choosing a treatment method, the anatomical features of these organs are taken into account. It has been determined that the effectiveness of treatment for primary BCSC of the nose and auricles is higher than recurrent one, and among the various treatment methods, the most effective and radical is the surgical method.

The digital transformation of healthcare is an integral part of the priorities in modern healthcare. A striking example of the practical implementation of compliance with the basic principles of digital healthcare is the Healthy Moscow project, which has been implemented since 2021, which has become a real breakthrough in Russia in ensuring accessibility and convenience in providing medical care to the population. The aim of the project is the early prevention of chronic non-communicable diseases, the formation of a healthy lifestyle and the improvement of the well-being of Moscow residents, as well as the development of a conscious attitude to taking care of their health.

[Organization of children's otorhinolaryngological care in conditions of biological risks: international experience].

The COVID-19 pandemic has spurred the introduction of new devices and technologies into the organization of otorhinolaryngological care, the development of safety measures and clinical work protocols in order to increase the safety of doctors and patients. Virtual outpatient clinics have been integrated into the pediatric and basic outpatient services, the potential of which for pediatric otolaryngology is considered quite significant. In otorhinolaryngological practice, the transition to the expanded use of telemedicine technologies (individual gadgets for examining ENT patients, including a direct access otoscope connected to an otolaryngologist's computer) was especially significant.

[Main anthropometric indicators of children and adolescents living in the Chuvash Republic in the dynamics of 137 years].

Anthropometric studies conducted in 1884, 1928, 1946, 1965 and 1999 to study the characteristics of growth and weight indicators of children living in the territory of modern Chuvashia, partly reflected the influence of the living conditions of children in certain historical periods of the country's development: revolutions, civil and domestic wars, post-war stabilization, «perestroika». Over the last 22-year period, from 1999 to 2021, there has been the largest increase in the growth rate of indicators of the physical development of children and adolescents, which is considered as a positive trend, a manifestation of ongoing acceleration processes. It was revealed that in modern children, physiological growth jumps in comparison with their peers in 1884, 1930, and 1999 occur earlier - in the prepubertal period.

[Organization of the work of the «Healthy Moscow» pavilions in order to conduct preventive examinations of the adult population in park areas, squares and recreation areas of the city of Moscow].

In modern conditions of global threats caused by infectious risks, the importance of programs and preventive examinations of the working-age population is increasing, which make it possible to identify groups of people at increased risk in the formation of health disorders, and to obtain objective data on the dynamics of morbidity and mortality of the population, to conduct long-term monitoring. The uniqueness of this project lies in the fact that it is based on a patient-centered approach that involves the individualization of the patient's diagnosis, professional counseling about risk factors and a healthy lifestyle, accompanying the patient until the completion of the examination, diagnosis and treatment. The organization of preventive examinations of the population within the framework of the Healthy Moscow program was the result of coordinated work and the realization of the professional potential of various services in the healthcare system, education, science and public administration.

[Methods to restore fine motor skills in stroke patients].

The review article considers the problem of nonmedical post-stroke rehabilitation, in particular the restoration of fine motor skills in patients in the early period of the disease. A review and analysis of various randomized controlled trials concerning the use of various rehabilitation methods both in monotherapy and in their combined application is carried out, and modern technical devices, with the use of computer technology and biofeedback, are reviewed. Proceeding from the presented literature data and their analysis, there are certain grounds for introducing modern apparatus complexes and robotized devices for fine motor skills restoration in post-stroke patients, especially in the early period, into the multimodal rehabilitation system.
