Exposure to high levels of nitrates in groundwater can have adverse effects on the health of residents who use groundwater for drinking. This study aims to assess the health risk associated with the ingestion of nitrates in well water in the town of M’bahiakro. Health risk maps were created on the basis of hazard quotients (HQ) using the US Environmental Protection Agency (USEPA) health risk assessment model. The results indicate that residents of the Koko, Dougouba and Baoulekro neighbourhoods, whatever their age, are potentially exposed to the toxic effects of NO3−during their daily intake of nitrate-contaminated well water, with reference to hazard quotients (HQ) greater than 1. Nitrate concentrations in the groundwater should therefore be controlled in order to prevent their harmful effects on the health of the population and guarantee its use in rice-growing activities in M’Bahiakro.展开更多

The increasing prevalence of metabolic risks in the 21st century has a profound impact on the disease burden associated with IHD. We analyzed the global, regional, and national burdens of IHD attributable to metabolic risks from 1990 to 2021.Methods The data were taken from Global Burden of Disease(GBD) study 2021. Deaths, disability-adjusted life years(DALYs),the average annual percent change(AAPC), age-standardized death rates per 100,000 persons(ASDR) and age-standardized rate per 100,000 persons(ASR) of DALYs ranging from 1990 to 2021, were extracted and stratified according to region, nationality, socio-demographic index(SDI), sex, and age. Additionally, the global future trends were predicted using Nordpred prediction model.Results Compared to 1990, in 2021, the number of death and DALYs from metabolic risk-attributed IHD increased globally by67.35% and 59.91%, respectively;whereas ASDR and ASR of DALYs showed a decreasing trend and the most severe impact was observed in male and elderly populations. In addition, the burden of disease showed an inverted V-shaped relationship with SDI from 1990 to 2021. AAPC showed a significant increase in developing countries and a decrease in developed countries. We also analyzed the effects of different risk factors including metabolic risk factors on IHD in different SDI regions and genders. The prediction of future disease burden showed that the number of death and DALYs will keep rising, while ASDR and ASR of DALYs will maintain a certain downward trend.Conclusions The results of this study highlighted the need for screening and intervention for metabolic risk factors in specific regions and populations, this should call for increased collaboration between developing and developed countries to reduce the burden of disease and improve the prognosis of patients with IHD.展开更多

文摘Fish constitutes the main protein source for the Amazonian population.However,the impact of different anthropogenic activities on trace element and metal accumulation in fish and their risks for human health at a regional scale remain largely unexplored.Here we assessed exposure levels of 10 trace elements andmetals(Cr,Mn,Fe,Ni,Cu,Zn,As,Cd,Pb,and Hg)in 56 samples belonging to 11 different species of fish from the Brazilian Amazon.We studied the relationship between exposure levels,fish origin,and fish feeding habits,and assessed toxicological and carcinogenic risks for the Amazonian population.No significant correlation was found between sampling site and exposure levels to the studied elements,but a significant difference was found between the accumulation of some metals and the position of the fish species in the food chain.The concentrations of Cr and Hg in fish flesh were found to exceed the Brazilian limits for human consumption.This study shows that current fish consumption patterns can lead to estimated daily intakes of Hg,As and Cr that exceed the oral reference dose,thus posing a toxicological concern.Furthermore,carcinogenic risks may be expected due to the continued exposure to Cr and As.The results of this study show that the consumption of wild caught fish in the Amazon region should be controlled.Moreover,continued monitoring of trace element and metal contamination in fish and on the health of the Amazonian population is recommended,particularly for riverine and indigenous communities.

文摘Excessive concentrations of toxic metals are a global threat to aquatic systems.Taking a typical tributary(Zijiang River,ZR)of the midstream of the Yangtze River as the research area,the concentration distribution and chemical fractions occurrence characteristics of five toxic metals(Cd,Cr,Cu,Pb,and Zn)were analyzed,their potential sources were explored,and their contamination and ecological risk was assessed.In the surface waters and sediments,there were high concentrations of Zn,a low concentration of Cd,and small spatial differences in concentration among the upstream,midstream,and downstream.In terms of speciation,Cd mainly existed in the acid-soluble fraction,Pb mainly existed in the reducible fraction,and Cr,Cu,and Zn mainly existed in the residue fraction.The potential sources in surface waters and sediments were determined to be industrial emissions and agricultural non-point sources through the absolute principal component scores–multiple linear regression model(APCS–MLR).Based on the assessment results of total concentration and speciation,Cd was the typical contamination element in ZR sediments.In addition,the secondary phase enrichment factor(SPEF)based on speciation underestimates the degree of Pb contamination,and the ecological risk of Zn assessed by the ratio of secondary phase and primary phase(RSP)and the risk assessment code(RAC)was higher than that of Cr,which was inconsistent with the results based on total concentrations.SOM and Al/Fe/Mn cycles in sediments influenced the geochemical behavior of toxic metals.
文摘The application of generative artificial intelligence(GAI)in the judicial domain represents an innovative approach to achieving digital justice.GAI’s functionalities are primarily exhibited in the enhancement of judicial efficiency,improving the accuracy and fairness of adjudications,promoting the uniform application of the law,and enhancing transparency and engagement in judicial processes.However,these advancements are accompanied by potential risks and challenges in technology,adjudication,and ethics.It is thus essential to strengthen privacy protection during the processing and transmission of data,ensure data security and confidentiality,and establish and refine clear legal norms regarding the roles,responsibilities,and legal obligations of GAI in judicial settings.In addition,ethical guidelines that delineate the behavioral boundaries and value orientations of GAI need to be formulated.Collectively,these elements can form a trinary model of technical controls,legal norms,and ethical constraints,to facilitate the modernization and intelligent development of the judicial system.

文摘Background Ischemic heart disease(IHD) represents the most significant disease burden among all cardiovascular diseases(CVDs). The increasing prevalence of metabolic risks in the 21st century has a profound impact on the disease burden associated with IHD. We analyzed the global, regional, and national burdens of IHD attributable to metabolic risks from 1990 to 2021.Methods The data were taken from Global Burden of Disease(GBD) study 2021. Deaths, disability-adjusted life years(DALYs),the average annual percent change(AAPC), age-standardized death rates per 100,000 persons(ASDR) and age-standardized rate per 100,000 persons(ASR) of DALYs ranging from 1990 to 2021, were extracted and stratified according to region, nationality, socio-demographic index(SDI), sex, and age. Additionally, the global future trends were predicted using Nordpred prediction model.Results Compared to 1990, in 2021, the number of death and DALYs from metabolic risk-attributed IHD increased globally by67.35% and 59.91%, respectively;whereas ASDR and ASR of DALYs showed a decreasing trend and the most severe impact was observed in male and elderly populations. In addition, the burden of disease showed an inverted V-shaped relationship with SDI from 1990 to 2021. AAPC showed a significant increase in developing countries and a decrease in developed countries. We also analyzed the effects of different risk factors including metabolic risk factors on IHD in different SDI regions and genders. The prediction of future disease burden showed that the number of death and DALYs will keep rising, while ASDR and ASR of DALYs will maintain a certain downward trend.Conclusions The results of this study highlighted the need for screening and intervention for metabolic risk factors in specific regions and populations, this should call for increased collaboration between developing and developed countries to reduce the burden of disease and improve the prognosis of patients with IHD.
文摘Non-obstructive azoospermia is a common condition associated with significant health risks,including increased mortality,cancer,and chronic diseases such as metabolic and cardiovascular disorders.This review aims to highlight the potential health challenges faced by men with this condition compared to fertile counterparts.Through a comprehensive bibliographic search on PubMed,using the following algorithm:(“infertility,male”[MeSH Terms]OR“azoospermia”[MeSH Terms])AND(“mortality”[MeSH Terms]OR“neoplasms”[MeSH Terms]OR“chronic disease”[MeSH Terms]OR“diabetes mellitus”[MeSH Terms]OR“heart diseases”[MeSH Terms]),we analyzed existing literature to explore the associations between infertility,specifically azoospermia,and adverse health outcomes.Findings indicate that infertile men are at a higher risk of death,various cancers(particularly testicular cancer),metabolic syndrome,diabetes,hypogonadism,and cardiovascular disease.Although research specifically addressing azoospermia is limited,available studies support the notion that men with this condition may experience heightened health vulnerabilities.Given these risks,it is imperative for healthcare professionals,especially urologists,to conduct thorough health assessments for men diagnosed with azoospermia.Informing patients of these potential health issues and integrating comprehensive evaluations into their care can facilitate early detection and intervention for life-threatening conditions.Ultimately,men with azoospermia should receive ongoing monitoring to address their specific health concerns,thus improving their long-term health outcomes.
