Summary: By analyzing the concentration of heavy metals in rice produced in northeastern Iran and the age-standardized incidence rate of colon cancer, the study found that areas with higher cobalt concentrations were associated with higher colon cancer incidence in men, while higher selenium concentrations were linked to lower incidence. Further investigation is needed to clarify the reasons for these discrepancies, and regular monitoring of heavy metal levels in consumed rice is recommended.

Summary: In this article, we propose a method for estimating large-dimensional factor models using principal component analysis and ordinary least square regression. Theoretically, we show that the proposed method can consistently estimate factor loadings, scores, and common components without any moment constraint. The convergence rates of the estimated parameters are provided. The method is validated through simulations and analysis of a financial dataset.

Summary: The development of urban agglomeration worsens air pollution caused by urbanization. However, the variations in urbanization process across different urban agglomerations may lead to unique regional air pollution characteristics and complicate its driving mechanism. This study focuses on 11 urban agglomerations in China with different levels of urbanization to examine the spatiotemporal heterogeneity of PM2.5 and its potential driving factors related to urbanization. The findings highlight the significant spatial heterogeneity of PM2.5 pollution and the substantial contribution of urbanization to regional PM2.5 pollution.

Summary: Machine learning was used to address the challenges of nonlinearity, output variations, and multidimensionality in the real-world usage of electrochemiluminescence (ECL) sensors. Closed ECL systems with luminol/H2O2-based electrochemistry were used to accurately measure the concentration of biomarkers such as cholesterol, choline, lactate, and glucose. Various regression ML models were employed to predict biomarker concentration and improve accuracy. Real blood serum analysis demonstrated the potential of the ECL device for practical applications.

Summary: This study investigated the spatial patterns of the 10 most prevalent cancers in northeastern Iran. Methods like Getis-Ord G* and Anselin Local Moran's Index were used to identify hotspots and local clusters. The study found that, except for breast cancer, all cancer types were more common in males. Cluster analysis revealed hotspots of breast cancer in the Southwest, skin cancer in the East/Southeast, and brain tumors in the North among men. Among women, hotspots were found for skin cancer in the East and Southeast, and bladder cancer in the Central and East. The study suggests a possible link between the high incidence of certain cancers and environmental factors.

Summary: This study provides a spatiotemporal visualization of cutaneous leishmaniasis (CL) cases in Iran at the county level from 2011 to 2020, detecting high-risk zones and noting the movement of high-risk clusters. The number of new CL cases decreased over the research period, with a regular seasonal pattern. Significant high-risk clusters covering a large area of the country were observed, along with spatial variation in the temporal trend analysis. Overall, the study emphasizes the importance of conducting spatiotemporal analyses at the county level for a more precise understanding of CL distribution.

Summary: This study investigated the relationship between environmental and socioeconomic factors and motor vehicle collisions involving young pedestrians in Mashhad, Iran. The findings revealed several factors, including population of young people, road area ratio, main road intersection ratio, average maximum speed limit, non-motorized travels, sidewalk area ratio, sidewalk disconnections, number of schools, unemployment ratio, illiteracy rate, and open space ratio, significantly associated with child pedestrian-motor vehicle collisions. However, these associations varied across the study area, suggesting the presence of unknown factors or interactions of known factors.

Summary: This study used multi-year data to predict pedestrian-road traffic accidents based on socioeconomic and built-environment factors. Logistic regression and fuzzy-analytical hierarchy process techniques were used to evaluate and assign weights to each factor. The susceptibility map for accidents was generated using the Technique for Order of Preference by Similarity to Ideal Solution. Accidents in 2020 were predicted using real accident data and Markov chain and cellular automata Markov chain models, with high prediction accuracy assessed by the Kappa index. The proposed methodology is generalizable and can aid urban planners in identifying high-risk locations and implementing preventive measures.

Summary: The study identifies fire patterns in the second-most populous city in Iran, Mashhad, from 2015 to 2019. Spatial scan statistics were used to analyze 29,889 fire events in the area and found four primary types of fires. The period from 12:00 to 23:00 was identified as high-risk for all fire incidents. Urban planners should consider socio-economic factors and prioritize high-risk neighborhoods for fire safety resource allocation. Future research could focus on high-risk regions to identify specific characteristics.

Summary: This study aimed to measure spatial access to hospitals in Sistan and Baluchestan Province in Southeast Iran using the enhanced two-step floating catchment area (E2SFCA) approach. The study revealed significant disparities in access to hospital beds in the province, with nearly 30% (938,399 people) of the population lacking access to any beds within a 30-min drive time. These findings have important implications for policymakers and local health planners as they can use the accessibility scores to prioritize resource allocation and improve access to healthcare services in underserved areas.
