Breast cancer (BC) is currently the most commonly diagnosed cancer in women. BC is most often derived from the epithelial tissue of the mammary gland and is a global problem due to the steady increase in morbidity and mortality in most countries. A particular problem today is the triple negative subtype (TNBC), which accounts for approximately 10-15% of breast cancer cases. BC occurs most frequently in young women and is characterised by various biological characteristics, an unfavourable clinical course and a poor prognosis. Recent studies to detect the effects of histamine receptors on breast cancer have shown that all H1R-H4R receptors are also hyperactive in the cancer microenvironment. Chronically maintaining a high level of histamine in the tumour-affected tissue contributes to increased angiogenesis at this site, induction of cancer cells proliferation and T lymphocyte dysfunction. The rising incidence of breast cancer is contributing to an increasing amount of research into targeted therapies. Studies on the effect of histamine antagonists through H1R-H4R receptors have proven their effectiveness in the treatment of breast cancer. Among those in the study, there was a reduction in tumour growth, cell proliferation and an increase in apoptosis. The use of histamine antagonists also contributed to a reduced risk of death from breast cancer and increased overall survival (OS). Therefore, targeted therapy is needed to improve the prognosis of patients with breast cancer.

Introduction and purpose: Diabetes mellitus (DM) is a metabolic disease caused by a chronic state of hyperglycemia, which results from a defect in the function or secretion of endogenous insulin. It is a disease that leads to serious complications such as blindness, lower limb amputation, ischemic heart disease or ischemic strokes. Description of the state of knowledge: The World Health Organization has identified diabetes mellitus as a global epidemic. Between 1980 and 2014, the number of people with diabetes increased from 108 million to over 422. Between 2000 and 2016, more than 7 million deaths from diabetes were reported in 108 countries, but this is an under-number due to the fact that many patients are not diagnosed with diabetes. The prevalence of diabetes in recent years is also higher in low and middle income (LMIC) countries than in high income (HIC) countries. DM also places a significant financial burden on the healthcare budget. Despite relatively large investments in medical care, clinical trials and public health interventions do not reduce the rate of increase in incidence. In the United States, annual healthcare expenditure for people with diabetes is 2.3 times greater than for people without diabetes.Summary: It is well known that diabetes significantly reduces patients' quality of life. It is influenced by both severe complications related to DM and adherence to strict medical recommendations. The low quality of life of diabetic patients contributes to depression, which is associated with not compliance with medical recommendations and increased mortality.

Introduction and purpose An insulinoma is the most common neuroendocrine tumor of a pancreas. This tumor produces insulin, which in excess causes hypoglycemic attacks, provoked by hunger or physical effort. Delays in diagnostic processes of the insulinoma are associated with the misattribution of symptoms to cardiac, psychiatric or neurological disorders. Thus, the suitable diagnostic procedures play a significant role as they ensure quick introduction of treatment. The purpose of this work is to evaluate advances in demanding diagnostically and therapeutically insulinoma. A brief description of the state of knowledge The used method was a literature review. The basic and the most common method of treating the insulinoma is a surgery. Due to this, finding precise location of the tumor preoperatively is crucial. In the diagnostics of the insulinoma both basic CT and MRI contrast enhanced and an endoscopic ultrasound, a selective arterial calcium stimulation test and the latest molecular imaging are used. In treatment process not only traditional surgical excisions were performed, but also laparoscopic and robotic surgeries turned out to be success. Conclusions Summing up, the insulinoma is a neoplasm with a wide range of therapeutic and diagnostic solutions, thanks to the progress that has been made in recent years. Although there are many difficulties on a diagnostic path of the insulinoma, new solutions and appropriate aproach make this process easier. Nevertheless, doctor’s diagnostic vigilance is essential, because consideration in the differential diagnosis the insulinoma is an essential step and without this step any further actions can be taken.

Introduction: Sauna bathing as a health-promoting activity has been known to mankind for millennia. Sauna session, which consists of alternate overheating and then rapidly cooling the body, has a beneficial effect on the health of the body confirmed by scientific research. In the last few decades, sauna bathing has become more available due to the growing market of recreational services such as water parks and sauna parks. Regular use of sauna bathing reduces the risk of cardiovascular diseases, musculoskeletal disorders, mental stress, accelerates the process of regeneration after physical exertion, as well as increases resistance to the harmful effects of certain environmental factors. Despite the health benefits known for many years, the physiological mechanisms occurring in the body during sauna sessions still remain unknown. Sauna bathing treatments can be an effective complement to the process of treatment and rehabilitation of patients with cardiovascular diseases, musculoskeletal diseases, respiratory tract diseases, skin diseases and many others. Material and methods: A literature analysis on sauna bathing was carried out within the Pubmed and Google scholar platforms. The following keywords were used in search: sauna bathing, infrared sauna, cardiovascular diseases.  Purpose of the work: The aim of the following analysis is to present a historical outline of the use of sauna bathing, the health aspect, risks and the assumptions and indicating an important need for further research into the effects of sauna bathing on the body.

Introduction: Alcohol is one of the most widely-used stimulants. It’s easily accessible, most socially accepted and usually not associated with potential harm it can do. Except for its addictive effect, it has a strong influence on humane systems.  In this analysis the influence of alcohol on the cardiovascular system will be examined. As it is not obvious whether alcohol usage should be only associated with harmful impact on cardiac activity, different types of alcoholic beverages should be examined.  In this work three different sub-groups will be analyzed. They were selected and divided by the beverage type and percentage as follows: beer, wine, high percentage liquors. As the majority of studies show, it’s important to underline the significance of not only the alcohol percentage implied, but mostly of the alcohol type. In favor of alcoholic beverages are only studies analyzing beverages containing low levels of alcohol, but abundant in other organic substances like resveratrol (in wine). Other studies considering other beverages, nonetheless of alcohol levels, diminishing effect on the cardiovascular (and other) systems is observed.    Material and methods: An analysis of scientific papers from Pubmed Google Scholar was performed, wchoch most accurately described the issue of diffrent type of alcohol bevereage on human health. The following keywords were used in search: alcohol, cardiovascular, wine, beer, spirits.  Purpose of the work: Aim of the following analysis is to systematize the knowledge based on latest research and findings about the impact of different alcohol beverages on cardiovascular system.
