RESUMO

A total of 456 nuclear tests were performed from 1949 to 1989 at the Semipalatinsk Test Site (STS) in Kazakhstan, as part of the nuclear weapon test program of the USSR. To identify if radionuclides such as 137Cs, 90Sr, 241Am, 239+240Pu were associated with radioactive particles, soil samples were collected at selected contaminated sites (i.e. Experimental field, Excavation sites, Fallout plume sections, Background global fallout area, and Degelen Mountain) within the STS. A series of techniques have been applied to identify the size distributions of radionuclides, the prevalence of radioactive particles in soils, and the degree of leachability of particle associated radionuclides by different agents. In addition, selected particles were characterized non-destructively using digital autoradiography, environmental scanning electron microscopy (ESEM) and synchrotron radiation microscopic X-ray techniques. Radioactive particles were identified at all sites; large vitrified particles were identified at epicenters, and the size of particles decreased along the plume with distance from the epicenters. The radioactive particles identified varied in composition, size and leachability. In general, 137Cs, 241Am, 239+240Pu were strongly associated with solid phases (90-99%) in soils, while 90Sr exhibited much greater variability. The fraction of 90Sr present in exchangeable forms was low close to epicenters, while the extractability increased along the plume as the particle size distribution decreased. The results suggest that at least four different types of radioactive particles are present at STS: 1) Relatively large spherical particles with a shiny glazed, melted surface with internal porous structure, and surface layers enriched in transuranic elements, identified at epicenters of detonations, 2) Vitrified irregular particles probably originating from debris of nuclear device with interactions from soil components, also identified at epicenters of detonations, 3) Particles with visually unchanged structure, containing micro-inclusions of fissile materials associated with soil components, also identified at epicenters; 4) Particles with amorphous structures associated with underground detonations, identified in soil in the vicinity of the entrance of the detonation tunnels at the Degelen Mountain. These were probably formed by secondary mechanisms due to sorption and fixation of radionuclides. Thus, the present work shows that the STS should be considered an important observatory site to link particle characteristics to specific sources and to release conditions as well as to ecosystem transfer of particle associated radionuclides.

RESUMO

Objective: To evaluate the effect of a disease management programme in Kazakhstan on quality indicators for patients with hypertension, diabetes and chronic heart failure. Methods: A supportive, interdisciplinary, quality improvement programme was implemented between November 2014 and November 2015 at seven polyclinics in Pavlodar and Petropavlovsk. Quality improvement teams were established at each clinic and quality improvement tools were introduced, including patient flowsheets, decision support tools, patient registries, a patient recall process, support for patient self-management and patient follow-up with intensity adjusted for level of disease control. Clinic teams met for four 3-day interactive learning sessions within 1 year, with additional coaching visits. Implementation was managed by five local coordinators and consultants trained by international consultants. National and regional steering committees monitored progress. Findings: Between July and October 2015, the proportion of hypertensive patients with the recommended blood pressure increased from 24% (101/424) to 56% (228/409). Among patients with diabetes, the proportion who recently underwent eye examinations increased from 26% (101/391) to 71% (308/433); the proportion who had their low-density lipoprotein cholesterol measured increased from 57% (221/391) to 85% (369/433); and the proportion who had their albumin : creatinine ratio measured increased from 11% (44/391) to 49% (212/433). The proportion of chronic heart failure patients who underwent echocardiography rose from 91% (128/140) to 99% (157/158). All patients set themselves self-management goals. Conclusion: This intensive, supportive, multifaceted programme was associated with significant improvements in quality of care for patients with chronic disease. Further investment in coaching capacity is needed to extend the programme nationally.

RESUMO

The history of climate is crucially important for any part of the world to understand the nature of climate change. In this context, precipitation reconstruction is still lacking in northern Kazakhstan. The purpose of this study is to present a reconstruction for the total precipitation of October of the previous year to July of the current year in northern Kazakhstan. Pinus sylvestris L. (Scots pine) forests in Burabai Region are quite important to collect samples to study the climate history. A regional chronology, covering the years of 1702-2014 of Pinus sylvestris constructed by using 289/466 trees/cores was used in the reconstruction. The gridded climate data for the years of 1950-2014 were used in the calibration and verification process. High and significant correlations were obtained between tree-ring widths and October to July precipitation in Burabai Region. Based on this significant relationship, reconstruction was performed for the years of 1744-2014. Adjusted R2, F-value, sign test, and r value were found as 0.38, 39.7 (P ≤ 0.001), 47+/17, and 0.62 for reconstruction, respectively. The reconstruction showed that 43 dry and 42 wet years occurred during the years of 1744-2014. Only a one-time four-year duration of the wet period was determined covering the years 1978-1981. However, three of six very dry years occurred after the 1950s. As a conclusion, extremity in recent decades is getting an increase in Burabai region.

RESUMO

The colorectal cancer is considered as the third most common malignant disease in the world. During last decade, the problem of colorectal cancer became especially urgent conditioned not only by increasing of number of metastatic tumors of colon and rectum, but also by implementation of high-tech methods of treatment that significantly improved the results of five-year survival period. Along with success of therapy, understanding of genomics of colorectal cancer and owing to extensive application of next generation sequencing, the opportunity of optimal choice of treatment options was offered. METHODS: The sampling included tumor material of 332 patients diagnosed with colorectal cancer, fixed in formalin and enclosed in paraffin, and treated in oncology dispensaries and centers and in the Kazakh Research Institute of Oncology and Radiology in 2010-2014. After morphological evaluation of the material quality, the molecular genetic analysis was applied to establish mutation of the KRAS gene using polymerase chain reaction in real-time. RESULTS: The study established that KRAS mutation rate in patients with colorectal cancer had no reliable dependency with the region of their residence, since statistical analysis of pair "region of residence - all KRAS mutations" had value of correlation coefficient rp = 0.1 (p = 0.05). CONCLUSIONS: colorectal cancer It was established that there is no reliable dependence of rate of KRAS gene mutation in patients with colorectal cancer in the region of their residence. The high rate of occurrence of mutated type of gene was detected in 3 regions (Kyzyl-Orda, North Kazakhstan and Almaty) within the range of 58.3-76.5% of cases. The wild type of KRAS gene was most frequently detected in patients from the Karaganda region (65.5%), South Kazakhstan (71.4%) and Almaty (60.7%).

RESUMO

Although global warming is an indisputable fact, there is still uncertainty about how climate change will occur at regional levels. Kazakhstan is the largest landlocked country in the world. To best manage this country's limited water resources, socio-economic development and environmental protection, a solid understanding of regional climate change impacts is needed. In this study, tree-ring width and δ13C chronologies were established based on 99 tree-ring samples of Schrenk spruce (Picea schrenkiana Fisch. et Mey.) collected in Almaty, Kazakhstan. Climate response analysis between the tree-ring chronologies and climate data indicates that summer mean temperature is the strongest climate signal recorded by tree-ring δ13C. We reconstructed temperature change in southern Kazakhstan since 1850 C.E. using the tree-ring δ13Ccorr chronology. The results show that the temperatures in southern Kazakhstan have risen at a rate of about 0.27 °C per decade over the past 166 years. However, the rate has increased by as much as 0.44 °C per decade over the past 30 years. Analyses of temperature and precipitation data show that the climate has alternated between warm-dry and cold-humid periods over the past 166 years. The extreme droughts of 1879, 1917 and 1945 were caused by the combination of continuously high temperatures and reduced precipitation.

RESUMO

The methodology for determination of 241Pu in soils of the main test sites of the Semipalatinsk Test Site (STS) has been developed. The results of 241Am and 241Pu activity determination in soil samples sampled at the main testing sites of the STS are presented. 241Pu/241Am activity ratio is calculated. In most cases, on local sites, 241Pu/241Am activity ratio is in a rather narrow range, which makes it possible to estimate 241Pu activity based on the results of 241Am gamma-spectrometric analysis. The accuracy of 241Pu activity estimation using this method will be about 50%, which is quite enough in most cases.

RESUMO

We provide a Kazakh whole genome sequence (MJS) and analyses with the largest comparative Kazakh genomic data available to date. We found 102,240 novel SNVs and a high level of heterozygosity. ADMIXTURE analysis confirmed a significant proportion of variations in this individual coming from all continents except Africa and Oceania. A principal component analysis showed neighboring Kalmyk, Uzbek, and Kyrgyz populations to have the strongest resemblance to the MJS genome which reflects fairly recent Kazakh history. MJS's mitochondrial haplogroup, J1c2, probably represents an early European and Near Eastern influence to Central Asia. This was also supported by the heterozygous SNPs associated with European phenotypic features and strikingly similar Kazakh ancestral composition inferred by ADMIXTURE. Admixture (f3) analysis showed that MJS's genomic signature is best described as a cross between the Neolithic East Asian (Devil's Gate1) and the Bronze Age European (Halberstadt_LBA1) components rather than a contemporary admixture.

RESUMO

BACKGROUND: Celiac disease (CD) is a systemic immune-mediated disorder developing in HLA genetically predisposed individuals carrying HLA-DQ2 and/or HLA-DQ8 molecules. Recent evidences supported a predominant importance of HLA-DQB1 locus and, in particular, HLA-DQB1*02 alleles. This diagnosis is poorly considered in Kazakhstan, because of the assumption that CD is not prevalent in this population. OBJECTIVE: To demonstrate that the genetic predisposition to CD in Kazakhstan is not negligible and is actually comparable to Western populations. METHODS: Through the analysis of HLA-DQ genotypes of healthy bone marrow donors from Kazakhstan's national registry, we estimated the HLA-related genetic predisposition to CD in the country. RESULTS: We demonstrated that the frequency of CD-related HLA-DQB1 alleles and, as a consequence, of predisposed individuals to CD in Kazakhstan is significant and comparable to countries with the highest disease prevalence. CONCLUSION: Considering the dietary style in Kazakhstan, including wheat as a staple food, these results provided a preliminary background of knowledge to expect a significant CD prevalence in Kazakhstan and Central Asia by implementing appropriate and cost-effective diagnostic strategies.

RESUMO

There is an assumption that with the disintegration of the Soviet Union, the Second World ceased to exist. Yet the demise of the Communist bloc as a geopolitical reality did not mean that it stopped exerting a defining influence over how people think and behave. This article examines how the postsocialist state in Kazakhstan deals with potential crises such as earthquakes and the extent to which the Soviet legacy still shapes intellectual debates, state structures, and civil society organisations in in that country. Drawing on fieldwork and interviews, this paper re-examines the Second World in its historical context and re-establishes it as a conceptual framework for considering disaster risk reduction in the former Soviet bloc. It argues that it is essential to pay attention to this legacy in Kazakhstan both in policy and practice if earthquake risk reduction is to be made more effective.

RESUMO

The access barriers to asthma basic treatment and medical care in many countries are an urgent problem and emphasize the need for population studies to examine the associated risk factors for barriers to health care, causes of severe exacerbations, disruption of life quality, and the development of preventive measures. The purpose of study was to evaluate the association of quality of life, access to medical care and emergency of severe exacerbation in persons with bronchial asthma in the Republic of Kazakhstan. The cross-sectional study was applied. The sample included 3,572 patients of both genders aged 18-59 years with bronchial asthma, registered in out-patient clinics of the Republic of Kazakhstan. The assessment of frequency of severe exacerbation in patients with asthma, depending on availability of medical care, demonstrated significant differences in groups of minimal, average and maximum decrease (χ2 = 160.66, 2057.06, 166.19, p<0.001). The most of patients in group with severe asthma exacerbations more than 3 times per year had signs of a maximum decrease in access to medical care - 53.5% and 42.11% were classified as a medium-level barrier of access. The indicator of quality of life was significantly lower in group of patients with severe exacerbation of disease more than 3 times per year in groups with severe access barriers as compared to group with similar number of exacerbations where the number of barriers was less than two - 10.85 vs. 15, 28 (t = 3.985, D.f. = 1, p = 0.003). The study permitted to conclude that improving quality and increasing availability of medical care of asthmatic patient is the key to managing course of asthma at stage of diagnosis and during treatment as well.

RESUMO

BACKGROUND: To provide the population with inexpensive and effective medical products of domestic production is one of the most important public health tasks. These may include therapeutic muds, the high therapeutic value of which is confirmed by many years of positive experience with peloid therapy. The basis for interest in therapeutic muds is their efficiency in treating many diseases and regularly discovered new opportunities for their use. OBJECTIVE: To strive to streamline the use of previously discovered therapeutic muds in Kazakhstan, to search for new hydromineral resources, and to register the latter as minerals. MATERIAL AND METHODS: The material was the results of the analysis of published data on studies of therapeutic muds, their use for medicinal purposes in sanatorium and extrasanatorium conditions, which had been prepared during the grant financing project 'Development of an innovative procedure for the qualitative and quantitative assessment of therapeutic muds in Southeastern Kazakhstan as hydromineral raw materials' (IRN AR 05130934) in 2018. RESULTS AND CONCLUSION: The paper provides a brief description of the results of the study of therapeutic mud deposits in Western Kazakhstan, North Kazakhstan, and the Almaty Region. It gives the main list of diseases in which the use of mud therapy is effective.

RESUMO

The aim of this study was to establish the prevalence, relative risks, and predictive factors of the development of arterial hypertension (AH) in workers of a uranium processing enterprise (UPE). An open cross-sectional comparative study of 809 UPE workers was conducted. The compared them to the 696 workers of the bearing plant, located at a distance of 10 km from UPE. Stratification was performed and odds ratios (OR), gross (RR) and standardized relative (SRR) risks of hypertension were calculated. Our results revealed a high prevalence of hypertension among UPE workers (24.8%), as well as greater risk of development of hypertension among workers of UPE in comparison to the personnel of the non-uranium enterprise: RR=2.4 and SRR=2.9. The most significant predictors of hypertension were burdened heredity (OR = 13.6), total radiation dose (OR=1.5), overweight (OR=1.1), high anxiety (OR=0.5) and systematic use of alcohol (OR=0.5). Thus, among workers chronically exposed to radiation toxicity, high prevalence of hypertension, excessive RR and SRR of developing hypertension and the presence of risk factors for hypertension were established.

RESUMO

Paranoplocephala omphalodes is a widespread parasite of voles. Low morphological variability within the genus Paranoplocephala has led to erroneous identification of P. omphalodes a wide range of definitive hosts. The use of molecular methods in the earlier investigations has confirmed that P. omphalodes parasitizes four vole species in Europe. We studied the distribution of P. omphalodes in Russia and Kazakhstan using molecular tools. The study of 3248 individuals of 20 arvicoline species confirmed a wide distribution of P. omphalodes. Cestodes of this species were found in Microtus arvalis, M. levis, M. agrestis, Arvicola amphibius, and also in Chionomys gud. Analysis of the mitochondrial gene cox1 variability revealed a low haplotype diversity in P. omphalodes in Eurasia.
