First national survey of anti-tuberculosis drug resistance in Azerbaijan and risk factors analysis.

SETTING: Civilian population of the Republic of Azerbaijan. OBJECTIVES: To determine patterns of anti-tuberculosis drug resistance among new and previously treated pulmonary tuberculosis (TB) cases, and explore their association with socio-demographic and clinical characteristics. DESIGN: National cross-sectional survey conducted in 2012-2013. RESULTS: Of 789 patients (549 new and 240 previously treated) who met the enrolment criteria, 231 (42%) new and 146 (61%) previously treated patients were resistant to any anti-tuberculosis drug; 72 (13%) new and 66 (28%) previously treated patients had multidrug-resistant TB (MDR-TB). Among MDR-TB cases, 38% of new and 46% of previously treated cases had pre-extensively drug-resistant TB (pre-XDR-TB) or XDR-TB. In previously treated cases, 51% of those who had failed treatment had MDR-TB, which was 15 times higher than in relapse cases (OR 15.2, 95%CI 6-39). The only characteristic significantly associated with MDR-TB was a history of previous treatment (OR 3.1, 95%CI 2.1-4.7); for this group, history of incarceration was an additional risk factor for MDR-TB (OR 2.8, 95%CI 1.1-7.4). CONCLUSION: Azerbaijan remains a high MDR-TB burden country. There is a need to implement countrywide control and innovative measures to accelerate early diagnosis of drug resistance in individual patients, improve treatment adherence and strengthen routine surveillance of drug resistance

Characterization of Genomic Variants Associated with Resistance to Bedaquiline and Delamanid in Naive Mycobacterium tuberculosis Clinical Strains

The role of mutations in genes associated with phenotypic resistance to bedaquiline (BDQ) and delamanid (DLM) in Mycobacterium tuberculosis complex (MTBc) strains is poorly characterized. A clear understanding of the genetic variants' role is crucial to guide the development of molecular-based drug susceptibility testing (DST). In this work, we analyzed all mutations in candidate genomic regions associated with BDQ- and DLM-resistant phenotypes using a whole-genome sequencing (WGS) data set from a collection of 4,795 MTBc clinical isolates from six countries with a high burden of tuberculosis (TB). From WGS analysis, we identified 61 and 163 unique mutations in genomic regions potentially involved in BDQ- and DLM-resistant phenotypes, respectively. Importantly, all strains were isolated from patients who likely have never been exposed to these medicines. To characterize the role of mutations, we calculated the free energy variation upon mutations in the available protein structures of Ddn (DLM), Fgd1 (DLM), and Rv0678 (BDQ) and performed MIC assays on a subset of MTBc strains carrying mutations to assess their phenotypic effect. The combination of structural and phenotypic data allowed for cataloguing the mutations clearly associated with resistance to BDQ (n = 4) and DLM (a = 35), only two of which were previously described, as well as about a hundred genetic variants without any correlation with resistance. Significantly, these results show that both BDQ and DLM resistance related mutations are diverse and distributed across the entire region of each gene target, which is of critical importance for the development of comprehensive molecular diagnostic tools

Epidemiology of hip fracture and the development of a FRAX model for Uzbekistan

Summary A prospective population-based survey in a region of the Republic of Uzbekistan determined the incidence of fractures at the hip. The hip fracture rates were used to create a FRAX® model to facilitate fracture risk assessment in Uzbekistan. Objective This paper describes the epidemiology of hip fracture in the Republic of Uzbekistan that was used to develop a country-specific FRAX® tool for fracture prediction. Methods During a 1-year (2016/17) prospective population-based survey in the Pap district of the Republic of Uzbekistan, hip fractures were prospectively identified from hospital registers, trauma centres and primary care and community sources. Age- and sex-specific incidence of hip fracture and national mortality rates were incorporated into a FRAX model for Uzbekistan. Fracture probabilities were compared with those from neighbouring Kazakhstan and Kyrgystan. Results Approximately 41% of hip fracture cases did not come to medical attention, and two thirds of patients overall were not admitted to hospital. The incidence of hip fracture applied nationally suggested that the estimated number of hip fractures nationwide in persons over the age of 50 years for 2015 was 16,764 and is predicted to increase more than three-fold to 60,272 in 2050. FRAX-based probabilities were higher in Uzbekistan than Kazakhstan or Kyrgystan. Conclusion The FRAX model should enhance accuracy of determining fracture probability among the Uzbek population and help guide decisions about treatment

Physical-Chemical Constants and Fatty Acid Composition of Zosima absinthifolia Link. Fruit Oil

Zosima absinthifolia is the only species of Zosima genus in Azerbaijan. The aim of this study was to determine the quantitative and qualitative determination of fatty acids in the fruits of the plant Zosima absinthifolia, which is widespread in Absheron, as well as to study its physicochemical and organoleptic properties, possible use in the pharmaceutical and food industries. The oil obtained from the fruits of the plant collected from the Absheron Peninsula (Bibiheybat) was analyzed by gas chromatography. The oil was obtained at 60 °C for 8 h by the extraction of the fruits in a Soxhlet extractor. The yield was 10.36%. Chromatographic analysis of the oil obtained from plant fruits allowed to determine 14 fatty acids. The main component of Z. absinthifolia fruit oil is oleic acid (74.36%). Small amounts of caprylic and palmitic acids were also found to be 8.9% and 5.39%, respectively. The lowest percentage is palmitinoleic acid (0.07%). Physical-chemical constants and organoleptic properties of Z. absinthifolia fruit oil were also analyzed and it was determined that the percentage of free fatty acids in our sample was 2.47%, the peroxide value 34.16 mg O/kg and the saponification number 200.23 mg KOH/g.</jats:p

Правовой анализ законодательства зарубежных государств в области борьбы с созданием, использованием и распространением вредоносных компьютерных программ

На данный момент во всем мире быстрыми темпами идет процесс информатизации. Практически все сферы общественной жизни так или иначе зависимы от нормального функционирования компьютеров, компьютерных систем и информационно-коммуникационных сетей. Одной из угроз функционированию компьютеров, их систем и сетей являются вредоносные компьютерные программы. По этой причине государства разрабатывают нормативные правовые акты с целью эффективной борьбы с распространением вредоносных программ, их использованием, а также их созданием. В данной статье проанализированы законодательные акты некоторых зарубежных государств, направленные на противодействие созданию, использованию и распространению вредоносных компьютерных программ.
