Considering that type 2 diabetes mellitus is a multicomponent disease and is associated with an extremely high risk of macrovascular complications (myocardial infarction, stroke and death from cardiovascular diseases), at present, much attention is paid to the choice of hypoglycemic drugs, given the individual characteristics of the patient. Preference is given to drugs of those classes that have a positive effect on cardiovascular outcomes. Along with relatively new molecules (inhibitors of the sodium-glucose cotransporter type 2 and agonists of glucagon-like peptide-1 receptors), the well-known drug pioglitazone, which belongs to the thiazolidinediones group, has not left the field of attention of researchers. Importantly, the cardioprotective effect of pioglitazone has been confirmed in several large randomized trials that showed a delay in atherosclerosis and a reduced risk of cardiovascular disease (PERISCOPE, CHICAGO, IRIS and PROactive). As an insulin sensitizer, pioglitazone reduces insulin resistance, has a protective effect on pancreatic β-cells, and also has a beneficial effect on components of insulin resistance syndrome (lowers blood pressure, lipid spectrum parameters) and improves the course of non-alcoholic fatty liver disease. There is evidence of possible side effects (weight gain, fluid retention, fractures), but their severity decreases with decreasing dose of the drug.

Radioactive iodine 131I is a theranostic isotope used both for diagnosis and therapy of benign thyroid diseases and thyroid cancer for 85 years. The formation of nuclear medicine is closely linked with the use of 131I. The history of radioiodine therapy began in 1941, when endocrinologist Saul Hertz for the first time used 131I to treat patients with Graves' disease. Since 1946 radioactive iodine 131I became widely available, and its effectiveness became public knowledge after reports on thyrotoxicosis treatment published in the Journal of the American Medical Association by multidisciplinary groups of scientists physicists and endocrinologists. In 1951, isotope 131I became the first Food and Drug Administration approved RP for the treatment of thyroid disorders. Around the same time on the basis of the First Moscow Medical Institute studies on the use of radioiodine isotopes in patients with thyrotoxicosis began. The head of the Soviet group on the studying of radioactive iodine was the physician-scientist Vera Georgievna Spesivtseva. The research works of medical physicists Edith Quimby and Leonidas Marinelli in optimizing therapeutic strategies using radioactive substances in the late 1940s and the wording of the ALARA (As Low As Reasonably Achievable) principle of minimizing exposure of ionizing radiation by the International Commission on Radiological Protection in 1954 contributed to the greater introduction of radionuclides into the medicine.
