Even though tick-borne encephalitis (TBE) has been a notifiable disease in Croatia since 2007, there are no or only limited data available on the occurring tick species in the endemic areas, on the prevalence of TBE virus (TBEV) in ticks, its distribution in Croatia, and its genetic characteristics. Reporting of human cases also is very scarce. The Central European subtype of virus (TBEV-EU) appears to be present in Croatia

The Impact

The objective: determining gene polymorphism features ERS1, CYP2D6 in patients with breast cancer (RHZ) and endometrial cancer (EC) and the impact assessment studied genetic characteristics compared to receptor status (immunohistochemical determination of expression levels of ER, PR) tumors and the results of the treatment. Patients and methods. article presents the results of complex clinical, morphological, clinical-genealogical, and molecular-genetic examination of 28 females: 19 patients with breast cancer (BC), 9 patients with endometrial cancer (EC), including 5 patients with primary-multiple tumors (PMT) with and without tumor pathology aggregation in families. Results. The It was determined that in patients’ families malignant tumors of breast, uterine body and/or ovaries prevail that corresponds to Lynch type II syndrome (family cancer syndrome). Molecular-genetic examination of genomic DNA of peripheral blood and histological sections for the presence of SNPs of ESR and CYP2D6*4 genes comparing with the results of immunohistochemical study of tumors for receptors ER and PR status have not found associations between these characteristics; although among EC patients the occurrence of genotypes 397ТТ and 351АА was significantly higher comparing with BC patients (55.55% and 10.5% for genotype 397ТТ,and 15.8% for genotype 351АА, respectively). At the same time the patients with BC and primary-multiple tumors (PMT) of female reproductive system organs (FRSO) that carried mutations in BRCA1 in all the cases demonstrated positive ER and PR receptor status and adverse combinations of polymorphous variants of the genes ESR1 (397СС, 397ТС) and CYP2D6*4 (1846G, 1846GA), suggesting combined effect of these factors on the development of malignant neoplasias of FRSO in families with positive family cancer history. In BC patients, receiving standard hormone therapy with tamoxifen, those, who had genotype 1846GG of the gene CYP2D6*4, in 3 patients (15.8%) of 19 (100%) patients disease recurrence was diagnosed. Conclusion. The obtained results allow clinical use of the assessment of polymorphism frequency of the genes ESR1 and CYP2D6*4 for selection of individual hormone therapy regimens schemes for BC patients, to increase efficacy of dispensary observation after finishing of special therapy for such patients, and also personalization of complex and combined treatment regimens. Key words: breast cancer, endometrial cancer, family cancer syndrome, single nucleotide polymorphisms (SNPs) of the genes ESR1, CYP2D6*4.

The Relationship

The aim of the study is to systematically analyze the data available in the modern literature on the relationship between endometrial thickness and the frequency of pregnancy in the program of assisted reproductive technologies (ART). Materials and methods. The review includes data from foreign and domestic articles found in PubMed on this topic. Results. The article presents data on the relationship between the thickness of the endometrium and the frequency of pregnancy in ART programs. The greatest number of studies is devoted to the evaluation of the relationship between the thickness of the endometrium and the frequency of pregnancy on the day of the ovulation trigger. Data are presented on the existence of a correlation between the thickness of the endometrium measured on the day of the ovulation trigger and the frequency of clinical pregnancy, as well as data on the need to evaluate the structure of the endometrium and the state of subendometric blood flow. The importance of multilayered (three-layered) endometrium as a prognostic marker of success in in vitro fertilization/intracytoplasmic sperm injection programs in the ovum is emphasized. The conclusion. The thickness of the endometrium can not be used as an argument for canceling the cycle or abolishing embryo transfer to the uterine cavity. Further studies in this direction are needed with a study of the morphological and molecular genetic characteristics of the endometrium, which in the future will allow us to evaluate the relationship between the thickness of the endometrium and the probability of pregnancy.

The Individual

The current adverse situation associated with the presence of a pandemic of allergic diseases is due to the lack of a scientifically based concept of treatment and prevention. The increased interest of researchers from different countries in the formation of immunological tolerance by modeling the intestinal microbiota is of high importance. Methods of influence on the microbial communities of the child's intestine should be as delicate as possible, taking into account the individual genetic characteristics of the microecosystem and the possibility of anaphylaxis. Until now, probiotic drugs have been widely used to correct dysbiosis, but data is gradually accumulating that there is no convincing evidence base for their use for the treatment and prevention of atopy. The use of bacteriophages is very relevant and one of the promising, actively studied areas of correction of intestinal biocenosis today, which are an alternative to antibiotic and probiotic medications. Selective decontamination of representatives of opportunistic flora, as the main factor in the implementation of the atopic phenotype, makes it possible to preserve and accelerate the formation of a unique and individual composition of the intestinal microbiota of the child, which can form an immunoregulatory balance. More than a century of experience in the use of bacteriophages indicates the safety of their use. Today, bacteriophages are actively used in various fields of practical medicine − obstetrics-gynecology, perinatology, urology, pediatric otorhinolaryngology, in the treatment of purulent-septic and intestinal infections. In some cases, bacteriophages are very effective against antibiotic-resistant pathogens. The active personalized use of bacteriophages in real clinical practice will make it possible to solve a number of serious, long-standing health problems in the Russian Federation and to win a world priority in this direction.
