Predictors of Early Mortality After Open Aorto-Iliac Reconstruction in Patients with Aortoiliac Occlusive Disease: An Observational Cohort Study

Background and Objectives: Open aorto-iliac reconstruction (AIR) for aorto-iliac occlusive disease (AIOD) remains a high-risk procedure due to multifocal atherosclerosis affecting coronary, cerebrovascular, and renal arterial beds. This study aimed to identify factors independent...

Mortality Proportionate Analysis of Cancer and Non-Cancer Diseases Among the Residents of Kazakhstan Exposed to Radiation from the Semipalatinsk Nuclear Test Site: Evidence from the State Scientific Automated Medical Registry

Introduction: The State Scientific Automated Medical Registry (SSAMR) of Residents of Kazakhstan Exposed to Radiation is a unique source of information for scientific research on the impact of radiation on population health. We aimed to conduct a proportionate mortality analysis...

Long-Term Tuberculosis Mortality Trends in Kazakhstan, 1998–2024: Regional Inequalities, Associated Factors and Health System Reforms

Background: Tuberculosis (TB) mortality remains an important indicator of disease burden, health system performance, and progress toward global TB control targets. This study aimed to assess long-term trends in TB mortality in Kazakhstan from 1998 to 2024 and to examine regional...

Elemental Composition, Sources, and Health Risks of Ambient PM2.5 in Ust-Kamenogorsk (Oskemen) and Pavlodar, Kazakhstan

Atmospheric pollution by fine particulate matter (PM2.5) poses a severe threat to public health in industrial regions of Kazakhstan, such as Ust-Kamenogorsk and Pavlodar, where a sharp continental climate exacerbates toxic element accumulation. This study aimed to compare the ele...

Machine Learning for Predicting Protective Behavioral Intention Following Serious-Game-Based Flood Risk Education

Climate change is increasing the frequency of hydrological extremes such as floods, requiring more effective approaches to build community preparedness alongside traditional flood risk management. This study develops and evaluates a serious-game-based flood risk education interve...

National time zone unification in Kazakhstan altered healthcare utilization and circadian re-entrainment patterns

Abstract In March 2024, the Republic of Kazakhstan unified its administrative time to UTC + 5, creating a nationwide natural experiment across a 30-degree longitudinal gradient. This structural shift offered a rare opportunity to evaluate how abrupt temporal restructuring correla...

Radiation Exposure and Cancer Mortality in Populations Living Around the Semipalatinsk Nuclear Test Site in Kazakhstan

Introduction. Mortality rates from malignant neoplasms can be considered a key marker of adverse environmental impacts. The aim of this study was to assess the association between exposure to ionizing radiation and the risk of mortality from malignant neoplasms among the populati...
