In-depth analysis and trends of cancer mortality in Kazakhstan: a joinpoint analysis of nationwide healthcare data 2014–2022

BackgroundCancer remains a leading cause of death both globally and in Kazakhstan, making it crucial to track its mortality trends. This study aimed to investigate cancer mortality trends from 2014 to 2022 in Kazakhstan.MethodsThis study utilized data from Kazakhstan’s Unified National Electronic Health System to perform descriptive data analysis and employed Joinpoint regression models to analyze average annual percent change (AAPC) in cancer-related mortality estimates. The authors also examined the mortality-to-incidence ratio (MIR) and proportionate mortality (PM).ResultsThe study analyzed 123,622 cancer-related death reports from 2014 to 2022. Major causes included trachea, bronchus, and lung cancer (16.01%), stomach cancer (11.43%), and colon and rectum cancer (10.05%), accounting for 37.48% of all cancer-related deaths. AAPCs showed a significant increase in mortality for individuals aged 18–44 (1.36%; 95% CI: 0.05%; 2.71%), while those aged 45–59 and 60–74 experienced decreases of -2.02% (95% CI: -3.05%; -0.96%) and − 2.10% (95% CI:-3.22%; -0.96%), respectively. PM was stable until 2019 but decreased from 2020 to 2021, while MIR increased during the same period. A significant decrease in oesophageal cancer mortality was observed in both females (-4.03%; 95% CI: -6.11%; -1.83%) and males (-2.44%; 95% CI: -4.89%; -0.02%), whereas ovarian cancer mortality increased by 0.95% (95% CI: 0.03%; 1.91%). In males, mortality from trachea, bronchus, and lung cancers decreased by -2.14% (95% CI: -3.00%; -1.25%), while “other neoplasms” rose by 6.21% (95% CI: 1.40%; 11.27%). Regional analysis highlighted variability, with the Kyzylorda region showing a pronounced increase in mortality (27.18%; 95% CI: 14.11%; 42.35%).ConclusionsDespite slight increases in MIR during the COVID-19 pandemic, overall cancer mortality trends remained stable. The findings highlight the need for targeted interventions, especially for individuals aged 18–44, ovarian cancer, and “other neoplasms”. Further research is needed to explore regional mortality variations.

Some aspects of zoning of agricultural land in Kyzylorda region of the Republic of Kazakhstan

Currently, the mechanism of territory zoning is one of the main criteria for preserving the productive potential of agricultural land. Reduction of fertile lands, increase in the number of degraded areas as a result of negative desertification processes, decrease in the efficiency of agricultural lands, their conversion into reserve lands, indicates the irrationality of the existing directions and technologies of territorial division of lands by purpose, underutilization of production possibilities. For example, in 1991 the size of land use was 218.3 million hectares, in 2022 land plots are used by 50% (115.9 million hectares). Purpose - to study theoretical and methodological approaches to the planning of agricultural land and rural settlements (RS), taking into account economically balanced development and transparent spatial distribution. Methods - analysis and synthesis, with the help of which the cause-and-effect relations of functional and natural-economic zoning were determined; statistical method allowed to analyze the factors of involvement of agricultural land by categories and information-statistical data on Kyzylorda region. Results - the problems of establishing functional zones for the purpose of regulating the agricultural land market were revealed, socially oriented indicators of land ranking on the basis of land registration materials were outlined, existing systems of land use management were shown. Conclusions - zoning of lands intended for agricultural production in the RS is carried out in order to determine the boundaries of assessment zones and correction factors to the basic rates of payment for land plots, and is also necessary as a tool for regularization of land resources of built-up areas. A necessary condition for ecologically acceptable agricultural nature management is compliance with a set of agrotechnical practices and measures.

Trends in Stage-Specific Kidney Cancer Incidence in Kazakhstan, 2005-2019.

The aim is to analyze the incidence of kidney cancer over a 15-year period, considering factors such as stage, age, sex, and morphological verification in the regional context in Kazakhstan. The retrospective study was done using descriptive and analytical methods of oncoepidemiology. The extensive, crude and age-specific incidence rates are determined according to the generally accepted methodology used in sanitary statistics. The data were used to calculate the average percentage change (APС) using the Joinpoint regression analysis to determine the trend over the study period. Among the meticulously documented 15,277 cases, a conspicuous male predominance was noted, comprising 53.7% of cases compared to 46.3% in females, with peak incidences observed within the 50-69 age cohorts. The average age at diagnosis exhibited a progressive rise over the study period, with discernible variations observed in age-specific incidence rates, particularly pronounced within the 60-84 age brackets. Noteworthy temporal trends indicated a consistent uptick in crude incidence rates, with distinct regional disparities manifesting higher rates in northern regions relative to their southern and western counterparts. Stratification by cancer stage unveiled a significant surge in stages I-II cases alongside a concomitant decrement in stage III incidences, complemented by reductions in stage IV occurrences and instances of unspecified disease stages. Morphological verification rates displayed regional variations, with an overarching ascending trajectory across most regions, albeit exceptions noted, notably in the Kyzylorda region. Our study identified a rise in kidney cancer incidence in Kazakhstan, likely reflecting global trends driven by increased risk factor exposure and incidental imaging findings. Regional disparities and varied stage distributions highlight the complexity of kidney cancer epidemiology. Despite advancements in early detection, delayed diagnosis persists, necessitating improved surveillance and diagnostic practices.

Treatment of functional disorders of gastrointestinal tract of calves with complex phytomineral preparation

Significant economic losses due to diarrhoea morbidity in newborn young animals lead to a decrease in the profitability of the sector in the structure of agricultural production. Therefore, the purpose of this study was to create and investigate the therapeutic effect of application of complex phytomineral preparation using local components: opoka of Taskala deposit and decoction of camelthorn (Alhagi maurorum) for treatment of diarrhoea in calves. The therapeutic effect of the preparation was studied in the conditions of dairy farm in Kyzylorda region on 5-7-day-old calves. The effect of the preparation was studied in a comparative aspect with an analogous preparation of imported production and the results obtained from healthy animals. Clinical, haematological, and biochemical methods of investigation were employed. The findings obtained suggest a high therapeutic effect of the created preparation. Its application allowed reducing the duration of the treatment period by 5-7 days compared to the imported preparation and restoring the positive dynamics of average daily gain as early as on the 5th day after the start of treatment. Haematological studies indicate stimulation of the immune system in animals that was manifested by a 14% increase in the count of lymphocytes and a 37% increase in the proteins of the γ-globulin fraction compared to healthy animals. These indices suggest an increase in the activity of the humoral part of the immune system in animals after treatment with the preparation. Another positive therapeutic effect of the preparation was observed in the protective effect on the liver of diseased animals. Despite the present effect of both preparations, the decrease in the activity of markers characterising hepatocyte destruction was higher with the Kazakh preparation. Thus, the created preparation is characterised by a higher therapeutic effect in comparison with the imported preparation and allow recommending it for treatment and prevention of diarrhoea in young animals

Nutrient regime and balance of nutrients in soil under forage crops under application of different types of fertilizers (on the example of Kyzylorda region)

Modern agriculture is facing a number of challenges, among which the efficient use of fertilisers to provide plants with the necessary nutrients is of particular importance. In particular, the growing focus on sustainable agriculture and the need to preserve soil resources underline the relevance of research into optimising fertiliser use. The purpose of the study was to identify effective methods of fertiliser use to provide plants with nutrients. To achieve this goal, the effectiveness of green manure, organic (manure) and mineral fertilisers under Sorghum and perennial grasses (Medicago sativa, Elytrigia, Agropyron) on saline soil was investigated. The study founded that organic fertilisers, such as manure and green manure, contribute to a more even supply of nutrients to plants compared to mineral fertilisers. This is particularly important in the context of nitrogen and phosphorus balance, where Medicago sativa has a positive nitrogen balance due to its ability to symbiotically fix nitrogen. Other crops studied, such as Elytrigia, Agropyron and Sorghum, showed a negative nitrogen balance on the control variant, but the application of N100P50K110 mineral fertiliser resulted in a positive nitrogen balance. The replacement of mineral fertilisers with organic fertilisers such as manure and green manure increased nitrogen inputs but also increased nitrogen removal from the soil due to the increase in phytomass yields. The results of the study confirmed the importance of transitioning to a more sustainable and environmentally friendly way of production in agriculture, which will ensure the development of the industry and increase its competitiveness in the international market. The practical significance of the study is to provide farmers with the opportunity to increase the yield of their crops and at the same time preserve soil fertility through the optimal use of nutrients contained in fertilisers

Cancer Incidence Relation to Heavy Metals in Soils of Kyzylorda Region of Kazakhstan.

The purpose of this study was to investigate the relationship of soil pollution factors such as heavy metal ions with the incidence of cancer in the Kyzylorda region of Kazakhstan. Concentrations of heavy metal ions in the soils of different sites of Kyzylorda region, Kazakhstan, were sampled and correlated with incidence of cancer in 2021. Chromium content in the soil exceeded maximum permissible concentration (MPC) in the samples for all sites except Kazaly and Shieli, and the highest excess of 2.8 MPC was found in Terenozek. Content of copper, lead, and cobalt ions was also increased and varied in the range 1.9-15.4, 1.2-4, and 1.2-2.44 MPC, respectively. In addition, lung cancer incidence was statistically significantly correlated with soil concentration to MPC ratio of copper, cobalt, and lead; colorectal cancer was correlated with soil concentration of chromium. Cases of invasive cancer and mutations were recorded Terenozek and Kyzylorda areas. The higher the soil concentration correlate with higher cancer incidence in Kyzylorda region, Kazakhstan.

RESEARCH OF WATER-SAVING AND HERBICIDE-FREE IRRIGATION TECHNOLOGY FOR RICE CROP UNDER WATER DEFICIT CONDITIONS IN KYZYLORDA REGION

Kyzylorda region is the main producer of rice in Kazakhstan. Annually, out of 195 thousand hectares of irrigated fields used in the region, about 80-90 thousand hectares are sown with rice. However, every year due to low water in the lower reaches of the Syr Darya River there are problems with water supply for water-loving rice crop. Prospects of rice production under conditions of water deficit in Kyzylorda region are conditioned by necessity of application of water-saving technologies providing favorable thermal, salt and nutrient regimes. Water consumption of rice culture is 9,0-11,0 thousand m3/ha depending on biological specificity of rice and this indicator is 3-4 times lower than irrigation norm of rice in the region. Most of the water excessively applied to rice fields is wasted in summer and increases secondary soil salinization and reduces crop yields. Besides, due to deterioration of technical condition of irrigation canals and collector-drainage systems, mineralized groundwater is located close to the ground surface. Undoubtedly, this will increase soil re-salinization and reduce crop yields. One of the most difficult problems in rice fields is weed control. Application of chemical deteriorates the ecological condition of the region and reduces its economic efficiency. As a result of research on the development of water-saving and herbicide-free technology of rice irrigation under conditions of water shortage in the Kyzylorda region was saved 6460-9070m3 of water per hectare, ie compared to the current irrigation regime was saved 25-30% of water, and rice yield increased by 6.0-8.0 centners per hectare. In addition, an effective method of weed control in rice fields is the destruction of weeds by water regime without the use of pesticides and the improvement of irrigation technology of rice crop. As a result of the research it was found that maintenance of 20 cm water layer in checks after full germination of rice seeds provides 84% weed suppression and high yield of rice without herbicides

Advancing Rice Yield Forecasting and Crop Assessment in Kazakhstan’s Kyzylorda Region: A Multisource Satellite Data Approach

The monitoring and prediction of rice yields are essential across various domains, including agriculture, environmental conservation, ecology, agricultural insurance, and land resource management. The central districts of Kazakhstan’s Kyzylorda region, encompassing 70% of the total rice cultivation area, are of particular importance for ensuring national food security. This study focuses on the central Kyzylorda region, specifically the Syrdarya, Zhalagash, and Karmakshi districts, which serve as the primary hub for rice cultivation in Kazakhstan. The primary objective is to advance remote sensing techniques tailored to evaluate crop conditions and forecast rice yields, accounting for the region’s unique soil and climatic attributes. The research methodology involves comprehensive analysis of Sentinel-2 and Landsat-8 satellite data, harmonized with ground-truth information. This analysis encompasses the latest rice crop data for 2020 and precise sowing dates.

IRRIGATION PROCEDURE (MODE) OF TOMATO GROWN BY THE LOW PRESSURE DRIP IRRIGATION METHOD

Presently, the Republic of Kazakhstan, particularly the Kyzylorda region, grapples with a significant water scarcity issue. In light of this, the utilization of the drip irrigation method plays a crucial role in the judicious management of water resources. In regions like Kyzylorda, characterized by pronounced drought conditions, the efficacy of employing a low-pressure drip irrigation system is notably high. This approach results in an augmented land utilization coefficient, savings in material and labor costs, and an enhanced efficiency in the utilization of irrigation water. The implementation of a drip irrigation system contributes to the improvement of soil nutrition, air circulation, and water-physical properties. It mitigates soil erosion risks, ensures optimal water utilization by supplying irrigation water directly to the roots of each plant, and thereby maximizes the plants' water utilization efficiency. The likelihood of achieving abundant, excellent, and consistent harvests from agricultural crops rises. This method offers several advantages compared to alternative irrigation techniques, including reduced labor costs, preservation of the soil's fundamental structure, prevention of surface soil folds, the ability to concurrently apply fertilizers to the root system area, a potential 30-100% increase in crop productivity, a 50-60% decrease in irrigation water usage, and suitability for use in areas with high slopes.

Inheritance of breeding traits in Karakul sheep under different selection approaches.

In the previous century, each intrabreed type of the Karakul sheep breed was characterized by significant numbers, representing a super population with rich genetic diversity. However, over time, the genetic diversity within the breed's gene pool has undergone significant depletion. At present, the Karakul breed is predominantly composed of only two small populations, distinguished by their fur colors: black and gray. Consequently, under such circumstances, genetic advancements in breeding endeavors are likely to be relatively limited, especially given the potential risk of these populations disappearing altogether in the future. Hence, the preservation and judicious utilization of the available genetic resources within the black and gray Karakul sheep populations hold paramount importance in breeding efforts. The primary objective of our research was to investigate the heritability of breeding traits among gray lambs through various selection options. The study was conducted at the "Kumkent" base farm in the Sozak district of the Kyzylorda region. Our findings revealed that the inheritance of gray and black fur colors across the different selection options occurred in a consistent ratio. In the first selection variant (a gray ram with even silver marking ♂ x a black jacket fur type ewe with intense pigmentation ♀), the proportion of gray offspring was 50.6%. Similarly, in the second selection variant (a black jacket fur type ram with intense pigmentation ♂ x a gray ewe with even silver marking ♀), the proportion of gray offspring was 49.6%. The percentage of black lambs obtained in both selection options was nearly equivalent, with 49.4% and 50.4% in the first and second variants, respectively.

Мониторинг загрязнения почвенного покрова нефтепродуктами и разработка способа его рекультивации

Introduction. Oil waste has a high degree of toxicity and poses a great danger to humans and to the natural environment as a whole. One of the most acute problems is the negative impact of oily waste. The negative impact of petroleum products on the soil can lead to irreversible changes in the chemical composition, physical biochemical and microbiological properties of the soil, which determine, among other things, its fertility. The main potential sources of soil pollution with oil and petroleum products include ground vehicles, oil storage facilities, oil refining enterprises, as well as transport transporting petroleum products. The study of the physico-chemical properties of ash and slag waste to reduce the anthropogenic load on the environment. In Kazakhstan, as a result of the production activities of a number of large oil-producing enterprises, huge amounts of oil-and-oil soils have accumulated, significantly polluting the environment. The areas of polluted lands continue to increase as a result of emergency oil spills. Therefore, on the territory of the Kumkol oil field, it is very relevant to conduct environmental monitoring of soil pollution and carry out reclamation measures to restore land fertility The purpose of the research. Environmental monitoring in the conditions of development of the Kumkol deposit and the development of an effective technology for the reclamation of contaminated lands through the use of highly effective biological products to reduce the anthropogenic load on the natural environment. Research materials. For the research, samples of smeared soils of various sites of the Kumkol deposit of the Kyzylorda region of Kazakhstan were used. Research methods. The choice of soil monitoring methods was carried out taking into account the available sources of pollution and types of soil pollution: chemical, biochemical, biochemical, microbiological, etc. The analysis of existing methods of ecological monitoring of soils shows that due to the high cost and technological complexity, the use of a number of them is limited. Therefore, an effective approach to determine the degree of contamination of soils with petroleum products is the use of bioindication and biotesting methods Research results and discussion. As a result of the environmental monitoring, the technology of recultivation of polluted lands was developed using a biological product obtained by composting rice husks with the help of aerobic and anaerobic soil microorganisms. The scientific novelty of the proposed method of recultivation of contaminated soils is confirmed by the patent of the Republic of Kazakhstan, which confirms the scientific and practical significance of the work. The results of the research can be useful in the reclamation of oil-contaminated lands in other regions and the restoration of their vegetation cover. Conclusion. The monitoring of soil pollution by oil and petroleum products shows that the main potential sources include ground transportation facilities, oil storage facilities, oil refineries and transport, which first brings petroleum products. The developed technology of biorecultivation, firstly, reduces the anthropogenic load on the soil surface due to the biodegradation of oil spills, and, secondly, at the same time, the disposal of spilled oil in the form of vermicompost is carried out. In the work, for the first time on the basis of the application of a new technology for the reclamation of contaminated land resources using a biological product obtained from waste of plant and food origin, a new approach to the problem of utilization of oil-contaminated soils and restoration of their fertility, with the production of vermicompost, is proposed. Suggestions for practical application. A new approach to the problem of utilization of oil-contaminated soils and restoration of their fertility, with the production of vermicompost, is proposed, which can be useful in solving environmental problems in other oil-producing regions of Kazakhstan.
