in obese patients (p=0.0016). A large prospective group is needed to expand the estimated body parameters to the IVF outcomes.One of the new directions in the study of reproductive disorders in obese women is the effect and receptor sensitivity of melatonin on the gonadotropic function of the pituitary gland and ovariogenesis, taking into account the chronology of «light pollution». At the present stage, there is very little literature on the influence of the aspects of «light pollution» on the problem of obesity and reproductive disorders in the literature. This review is an attempt to combine the above problem in terms of the impact of «light pollution» and the level of receptor sensitivity of melatonin in women of reproductive age with obesity. The literature search was carried out in Russian (eLibrary, CyberLeninka.ru) and international (PubMed, Cochrane Library) databases in Russian and English. Free access to the full text of the articles was a priority. The selection of sources was prioritized for the period from 2015 to 2019. However, given the insufficient knowledge of the chosen topic, the choice of sources was dated from 1992. The work was carried out as part of the study «Central and peripheral pathophysiological mechanisms of development of adipose tissue diseases, taking into account clinical and hormonal characteristics» 2020-2022.

The Republic of Tyva is a region with a proven severe natural iodine deficiency and a high prevalence of IDD (iodine deficiency disorders). However, in the region in certain periods of time, measures were taken to eliminate iodine deficiency in the diet of the population. The article presents the results of the October 2020. Voxtalisib by specialists of the Endocrinology Research Centre, a control and epidemiological study aimed at assessing the current state of iodine supply in the population of the Republic of Tyva. The study was carried out on behalf of the Ministry of Health of Russia within the framework of the state task «Scientific assessment of the need to take additional regulatory legal and other measures to eliminate iodine deficiency in pilot regions with severe iodine deficiency».

Assessment of iodine supply of the population of the Republic of Tuva.

The research was carried out in three settlements of the republic - years. Kyzyl, Shagonar, Saryg-Sep settlement. A total of 227 pre-pubertal schoolchildseholds using iodized salt indicates the effectiveness of preventive measures in the-region.

Results of assessment (median urinary iodine concentration) confirm that population of Tuva, Russian Federation, has optimum iodine nutrition. The prevalence of goiter in schoolchildren significantly decreased compared to earlier assessments. The proportion of households using iodized salt indicates the effectiveness of preventive measures in the -region.The exact physiological basis for the suppression of growth hormone secretion by oral glucose intake remains unknown, despite the widespread use of the oral glucose tolerance test in endocrinology. Lack of growth hormone suppression by glucose occurs in about a third of patients with acromegaly, as well as in other disorders. It is currently known that the secretion of growth hormone is affected by various factors, such as age, gender, body mass index, and the redistribution of adipose tissue. There is also evidence of the impact of overeating as well as being overweight on the secretion of growth hormone. It is known that both of these conditions are associated with hyperinsulinemia, which determines the possibility of its predominant role in suppressing the secretion of growth hormone. The purpose of this review is to discuss the accumulated data on the isolated effects of hyperglycemia and hyperinsulinemia on growth hormone secretion, as well as other metabolic regulators and conditions affecting its signaling. Understanding of the pathophysiological basis of these mechanisms is essential for further research of the role of glucose and insulin in the metabolic regulation of growth hormone secretion. However, the studies in animal models are complicated by interspecific differences in the response of growth hormone to glucose loading, and the only possible available model in healthy people may be the hyperinsulinemic euglycemic clamp.

Quality of life (QoL) assessment before and after surgical treatment in patients with primary hyperparathyroidism (PHTP) may be useful for comprehensive evaluation of the treatment effect, as well as for monitoring of the patient' condition after surgery, including in real clinical practice.

The aim of the study was to validate and test the Russian version of the PHPQoL questionnaire for assessment of thequality of life (QoL) in patients with primary hyperparathyroidism (PHPT) for further application in clinical practice and research in Russia.

The linguistic and cultural adaptation of the PHPQoL questionnaire was carried out in accordance with international guidelines. Psychometric properties of the tool, namely, its reliability, validity and sensitivity were tested in the focus group of patients with PHPTResultsIn the whole, 65 patients with PHPT were involved into the study (mean age - 52.3 ± 10.5 years, 97% - -women) 67.7% patients were symptomatic, 35.4% patients had moderate or severe hypercalcemil practice in Russian endocrinology settings has been demonstrated.

The implementation of standardized protocols for combined treatment of cancer into clinical practice inevitably leads to a long-term consequence.

To study the prevalence of endocrine disorders, to assess the prevalence and degree of decline of bone mineral density (BMD) in individuals who have undergone combined treatment of malignant brain tumors in childhood and adolescence.

A retrospective study was conducted with 59 young adults (31 men; 28 women) who have undergone surgical treatment of malignant brain tumour followed by radiation treatment (craniospinal radiation in combination with or without polychemotherapy). Group I consisted of 37 patients, who were treated between the ages of 3 and 16years. Group II included 22 patients who received treatment between the ages of 16 and 38 years.

GH deficiency according to the results of the insulin hypoglycemia test was diagnosed in 48 patients (81%), 22-patients had secondary adrenal insufficiency (37%). The majority of those examined (33 patients (56%)) osteopenic conditions determines the relevance and need for early diagnosis to prevent further bone loss, reduced bone strength and therisk of fractures.

The results show that patients need to be monitored annually and for life after the combined treatment of malignant brain tumors in order to detect the long-term effects of the treatment. The high incidence of osteopenic conditions determines the relevance and need for early diagnosis to prevent further bone loss, reduced bone strength and the risk of fractures.Backgraund Acromegaly is a multi-organ disabling disease, the effectiveness of treatment of which directly depends on timely diagnosis. Latent course and delayed diagnosis increase the exposure of pathological hypersecretion of growth hormone and insulin-like growth factor-1, contributing to the development of irreversible systemic and metabolic changes in the body that negatively affect survival.

The aim of the study was to clinically test a comprehensive diagnostic approach using selective screening to detect cases of acromegaly in patients with combined somatic diseases.

The diagnostic search algorithm included a 2-stage questionnaire, expert assessment of the clinical status, laboratory and instrumental examination. The inpatient examination included the use of additional laboratory and instrumental methods and expert evaluation of the results obtained by filling out a doctor's questionnaire. When the score was higher than 18 points, a more specific examination was performed double determination of thema and 7 - -macroadenoma).

As a result of the study, among the group of 1249 patients (mean age 58±13 years) with the presence ofconcomitant diseases, 9 newly identified patients with acromegaly were found who were prescribed adequate treatment. The introduction of selective screening technology into the practice of an endocrinologist will improve the effectiveness ofdiagnostic search for patients with acromegaly, more accurately assess the prevalence of the disease in Russia and theneed for specialized medical care.

The objective of the NMCPMED will be not only the creation of a system of personalized treatment, but also the training of new specialists for medicine. Fundamental researches, carried out on the basis of the already existing institutes and laboratories of the NMRCE will be expanded by creating new laboratories of the NCPMED created de novo in accordance with the approved project. This article introduces the reader to the most important laboratories that would be created in NCPMED. These are laboratories of general, molecular and population genetics, bioinformatics, pharmacogenomics, microbiota, genome editing, mathematical and digital technologies, non-invasive technologies for the diagnosis of endocrinopathies, cellular technologies, artificial intelligence and a fundamentallyesearches that will allow them to significantly improve the methods of diagnosis and treatment.Radiotheranostics is a radionuclide therapy based on the results of molecular imaging with various radiopharmaceuticals, allowing in vivo whole body imaging (SPECT, PET), and then systemically and at the same time selectively acting on pathological metabolic processes caused by a pathological process. In recent years, thanks to advances in the development of nuclear medicine (an increase in the number of cyclotrons, SPECT / CT and PET / CT in medical institutions) and, particularly, novel radiopharmaceuticals - in the world, radiotheranostics is developing very rapidly. The emergence of new radioligands labelled by 177Lu, 131I, 225Ac and other radioisotopes in the world have initiated a large number of clinical trials of radioligand therapy of neuroendocrine and chromaffin tumors, prostate cancer, etc. Radiotherapy as a new and very promising direction of nuclear medicine and it is perfectly integrated into modern diagnostic algorithms in the field of endocrinology and oncology. Methods of intraoperative radionavigation make it possible to increase the efficiency and safety of surgical methods, external beam radiation therapy, and brachytherapy. In my opinion, the future of personalized medicine will be predominantly determined by the integration of radiotherapy, multimodal imaging, intraoperative navigation and existing/new methods of diagnosis and treatment, in combination with applied genomic and post-genomic technologies.
