Comparing Efficiency of Rice Washing and Soaking Processes in Reducing the Amount of Aflatoxin B1

Contamination of some agricultural products by mycotoxins has exposed the human and animal health to serious concerns. Aflatoxin B1 is the most toxic type of aflatoxins, which is of the highest amount in different foods, including rice, among various types of aflatoxins. The present study was aimed to evaluate the amount of this toxicant in the consuming rice in Yazd city and investigate the effect of rice washing and soaking process on reduction of the mean concentration of aflatoxin B1. The present study was a descriptive-analytical one, in which 36 rice samples (18 domestic types and 18 foreign types of rice) were randomly selected from the rice distribution centers in Yazd city. The Standard No.6872 of the Institute of Standards & Industrial Research of Iran (ISIRI) was used for measuring the amount of aflatoxin B and G toxicants using HPLC (high pressure or performance liquid chromatography) method and purifying by immune affinity column. Analysis of the collected data was performed using SPSS-22 statistical software as well as the statistical methods of one-way ANOVA and Tukey HSD. The mean concentration of aflatoxin B1 in domestic and imported rice was measured equal to 1.461 and 0.508ng/g, respectively. The contamination rate in the imported rice was lower than that in the domestic one, while there was no significant relationship between them (p≥0.166); furthermore, the effect of soaking process on reduction of the toxicant amount in one and ten hours of soaking was statistically insignificant. There was no significant relationship between the effect of a single time of washing and reduction of the amount of toxicant; however, in case of three and five times of washing, the amount of toxicant exhibited a reduction of 68.2% and 98.7%, respectively, which was statistically significant (

Worldwide incidence and mortality of bladder cancer and human development index: An ecological study

Background and Objective: Bladder cancer (BC) is the most common cancer of the urinary and genital tract. Many factors, including environmental and socioeconomic factors, also affect the incidence and mortality of BC. The aim of this study was to evaluate the epidemiology of BC incidence and mortality worldwide based on the data extracted in 2018. Materials and Methods: The present study is a descriptive-analytic study that extracts the incidence and mortality rates of cancer from the World Bank in 2018. The incidence and mortality rates and BC distribution maps were drawn for world countries. To analyze data, correlation test and regression tests were used to evaluate the correlation between the incidence and mortality with the Human Development Index (HDI). The statistical analysis was carried out by Stata-14 and the significance level was estimated at the level of 0.05. Results: The results showed a positive and statistically significant correlation between the incidence (r = 0.587, P < 0.0001) and mortality (r = 0.271, P < 0.001) of BC with the HDI index. The results showed that there was a positive correlation between the incidence of BC with Gross national income per 1000 capita (GNI) (r = 0.405, P < 0.001), mean years of schooling (MYS) (r = 0.525, P < 0.001), life expectancy at birth (LEB) (r = 0.566, P < 0.001), and expected years of schooling (EYS) (r = 0.574, P < 0.001). In addition, there was a positive and statistically significant correlation between mortality rate with GNI/1000 capita (r = 0.186, P < 0.01), MYS (r = 0.227, P < 0.01), LEB (r = 0.305, P < 0.01), and EYS (r = 0.250, P < 0.01). Conclusion: Given that the incidence and mortality of BC in high-HDI countries is higher, more research in these countries is needed to identify the factors affecting the incidence of disease in these countries. We can perform prophylactic actions to prevent the incidence and mortality of this cancer by identifying the risk factors of the aforementioned disease

Epidemiology of mortality induced by acute respiratory infections in infants and children under the age of 5 years and its relationship with the Human Development Index in Asia: an updated ecological study

Aim: Acute respiratory infection (ARI) is the most commonly reported disease in children. This study was conducted to investigate the epidemiology of mortality from ARI and its relationship with the Human Development Index (HDI) in children under the age of 5 years. Subjects and methods: The study data included the HDI, neonatal mortality rates, and the mortality of children under the age of 5 years due to ARIs retrieved from the World Bank. In this study, the bivariate correlation method was employed and a significance level of less than 0.05 was considered. Results: The mortality of children under the age of 5 years (r = − 0.784, p < 0.0001) and neonatal death (r = − 0.792, p < 0.0001) induced by ARIs was negatively correlated with the HDI. There was also a significant negative correlation between neonatal death caused by ARIs and gross national income (GNI) per capita per 1000 lives (r = − 0.453, p < 0.001), mean years of schooling (r = − 0.645, p < 0.001), life expectancy at birth (r = − 0.801, p < 0.001), and expected years of schooling (r = − 0.736, p < 0.001). A negative and significant correlation was also observed between the ARI-induced mortality of children under the age of 5 years and GNI per capita per 1000 lives (r = − 0.469, p < 0.001), mean years of schooling (r = − 0.619, p < 0.001), life expectancy at birth (r = − 0.771, p < 0.001), and expected years of schooling (r = − 0.756, p < 0.01). Conclusion: The components of the HDI are directly related to ARI deaths. Therefore, a careful analysis of these indicators in countries with a low HDI can be effective in promoting health and reducing ARI-related mortality in children

Effect of Human Development Index on Tuberculosis Incidence in Asia: An Ecological Study

Objective: Tuberculosis (TB) is a global health concern and is one of the main reasons responsible for the death of people by infectious diseases. We conducted this study to investigate the effect of human development index (HDI) on the incidence of TB in Asia. Methods: This ecological study was conducted in Asia to evaluate the correlation between the incidence of TB and HDI (life expectancy at birth, years of education mean and gross national income per capita). Data on TB from 2000 to 2016 were obtained from the World Bank Institution. The bivariate method and regression test were used to evaluate the correlation between incidence and mortality with HDI. Statistical analysis was conducted using Stata-14, and the significance level was considered 0.05. Results: In the recent years, the most occurrence of this disease in Eastern Asia is reported in Democratic Republic of Korea (513 persons/100,000), South-Eastern Asia in Philippines (520-590 persons/100,000), Cambodia (345-575 persons/100,000) and Timor-Leste (498 persons/100,000). A significant negative correlation was found between the incidence of TB and the HDI index in South Eastern (R = -0.609, P < 0.05) and South Central Asia (R = -0.793, P < 0.05). The results of regression analysis indicated that the increase in life expectancy at birth (LBE) (B = -11.45, P < 0.05) and MYS (B = -9.6, P < 0.05) caused a statistically significant decrease in the incidence of TB as well. Conclusion: The incidence of TB has a correlation with the human development index (HDI) in several Asian countries. Therefore, to reduce the incidence of the disease and prevent from it, the human development index should be considered as an effective factor in the occurrence of the disease, particularly in developing countries.

Predictive factors of anxiety and depression in COVID‐19 survivors: A cross‐sectional study

Abstract Background Depression and anxiety are among the most critically recognized psychological complication of the COVID‐19 pandemic. Aim This study aimed to examine the two predictors among COVID‐19 survivors in Ahvaz, Iran, in 2022. Methodology Using a descriptive‐analytical design, 347 COVID‐19 survivors referred to hospitals in Ahvaz were meticulously examined. The database of the COVID‐19 registration system contained primary information about the samples. For data collection, questionnaires, including the Beck Anxiety and Depression Inventory and a demographic questionnaire, were utilized. Results The results revealed a significant relationship between anxiety score and family size (p = 0.019), education level (p < 0.001), occupation (p = 0.015), household income status (p = 0.017), disease history (p = 0.017), ethnicity (p < 0.001), disease severity (p < 0.001), and quarantine period (p < 0.001). Furthermore, a significant correlation was observed between the average depression score and gender (p = 0.023), number of family households (p = 0.009), level of education (p < 0.001), occupation (p < 0.001), household income (p < 0.001), disease severity (p < 0.001), disease history (p < 0.001), and quarantine period (p < 0.001). Moreover, linear regression analysis indicated only a significant relationship between depression scores and the quarantine period variable (p < 0.001), among others. The simultaneous examination of all variables on depression disorder highlighted a meaningful relationship between depression score and disease history (p = 0.013), occupation (p = 0.002), household income status (p = 0.002), and family size (p = 0.039). Conclusions This study revealed a significant relationship between certain demographic variables, such as quarantine period, disease history, employment status, household income status, and the number of family households, and an increase in the average depression and anxiety score
