This study aimed to determine the hotspot areas for Cutaneous Leishmaniasis (CL) in Fasa city and assess the relations between the geographical factors with CL incidence using spatial analysis.
Materials and MethodsThis ecological study was conducted in Fasa city, data of the CL disease such as the total number of CL cases and the population at risk from 2009 to 2014. Weather conditions' data including the means of temperature, humidity, rainfall, sunny days, rainy days, and evaporation were collected from the weather forecast centers in Fars province. The disease cases' information such as the number of disease cases was collected from all healthcare centers located in Fasa City. Ordinary Least Square (OLS) and Global Moran’s Index (GMI) were used to assess the associations of the various environmental variables with CL incidence and to map clustering of CL cases across the region.
ResultsThe cumulative incidence of CL was 16 per 10,000 populations during a six-year period. The results showed the southern area of Fasa as a hotspot area which is considered as hyperendemic foci for CL. OLS revealed a high incidence of CL in areas with maximum temperature, mean of temperature, mean of evaporation, sunny days and wind velocity.
ConclusionA spatial disease pattern was found in the present study. Hence, substantial consideration to environmental data leads to not only suitable protection against CL but also designing a suitable measure for the prevention and control of the disease.

Recently, changes in people's lifestyles and new eating habits have diminished the importance of main dishes and have led to increasing the consumption of fast foods. Therefore, paying close attention to the health conditions and safety of the food provided in these centers can dramatically reduce the incidence of various diseases. The present study examines the environmental health status and the quality of used frying oils (the most important health assessment indicators of fast food restaurants) in the fast food shops and restaurants of the metropolis of Mashhad in the areas adjacent to the holy shrine which has the highest number of pilgrims and tourists.
Materials and MethodsA total number of 120 of fast food shops were selected by quota sampling method and were sampled during peak working times. The environmental health status of these centers was evaluated based on food, drink, cosmetics, and health material regulation. Demographic data of personnel, area and antiquity, type, duration and frequency of using oil, the temperature, TPM, and FFA were also measured.
ResultsAccording to the results; 32.5% of the subjects were in hygienic status, and 67.5% of the subjects were in sanitary status. Palm oil was the most widely used oil type. TPM and FFA indices were in the unfavorable condition in 49 samples (40.8%) and 75 samples (62.5%), respectively. There was a significant relationship between temperature, the period of using oil and TPM, and FFA indices.
ConclusionAccording to the high volume of customers, quality and health assurance of food is of utmost importance. Therefore, the importance of renovating the buildings, training the operators and staff, continuous monitoring, and applying severe legal measures can be the most important corrective actions.

Consumption of vegetable products is increasing commonly in the world because they are recognized as an important source of nutrients, vitamins, and fiber for humans. Salads are among the most widely used foods that are also known as the most contaminated foods in restaurants. This study was conducted to determine the microbial contamination of salad-preparing tables and salad-serving dishes.
Materials and MethodsThis study was conducted at 39 restaurants in Mashhad City in Iran during 2017. In this regard, 78 samples were determined from the salad preparing tables and serving dishes. Samples were tested for cleanliness status using Adenosine Triphosphate (ATP)-bioluminescence method as a rapid test.
ResultsAccording to the ATP bioluminescence device, 43.6% of the assessed dishes were clean, 38.5 % were dirty, and 17.9 % were not adequately clean. According to the results of ATP bioluminescence device for tables, 23.1 % of the tested tables passed the test, 15.4 % were classified in the caution status, and 61.5% failed.
ConclusionThe ATP method has been widely used, especially in the food industry, as a rapid method for measuring general levels of cleanliness. However, this method is not a reliable replacement for measuring the microbial contamination. The ATP bioluminescence should not be used as a substitute for quantitation of microbial load.

Nowadays, water has turned into one of the biggest challenges of the current century, which can be the origin of numerous positive and negative changes across the world. Iran is one of the driest countries with a quarter of the average annual precipitation on a global scale. Thus, the purpose of this study was to investigate the relationship between religious attitudes and tendency towards conserving water in high school students in Zarrin Dasht city, Iran.
Materials and MethodsThis descriptive cross-sectional study was conducted in 2017. To this end, 800 individuals (400 females and 400 males) were selected using random sampling method by taking into account the proportion of students in each school. To collect the data, two questionnaires of the water conservation tendency inventory containing 12 items and religious attitude questionnaire with 60 items were employed. Then, data analysis was performed using SPSS (version 24) and by running the Chi-square test, Pearson correlation coefficient, as well as descriptive statistics (P = 0.05).
ResultsThe mean scores of religious attitudes and tendency towards conserving water among the participants were equal to 36.18 and 175.83, respectively. Moreover, a significant relationship was found between the students’ religious attitudes, their demographic variables of age and gender, tendency to conserve water, and number of family members (p ˂ 0.05). Moreover, the correlation between religious attitudes and tendency towards saving water was also statistically significant (p ˂ 0.05, r = 0.81).
ConclusionConsidering religious attitudes and tendency towards conserving water, religious and moral inputs should be reinforced related to water-saving in students. This can extend their attitudes towards optimal water consumption within the society.

Analyzing the health risk associated with the microbial contamination of seawater is necessary to ensure that there is not any threat to human or environment. The aim of this study was to evaluate the microbiological quality of Caspian sea water using indicator bacteria. Some Physicochemical parameters were studied to assed their association with the contamination level of Caspian sea water due to the important role in the growth organisms in the seawater.
Materials and MethodsIn this study, 100 samples were collected from the northeastern zone of the Caspian sea, Iran, from November 2017 to December 2018. Total coliform, Fecal coliform, E.coli, Fecal Streptococcus and Clostridium perfringens were the indicator bacteria and temperature, pH, electrical conductivity, chloride and turbidity were water physicochemical factors according to standard methods.
ResultsThe finding showed that the mean of Total coliform, Fecal coliform, E.coli, Fecal Streptococcus, and Clostridium perfringens were 614.72 ± 516.13, 62.11 ± 235.30, 49.69 ± 188.24, 348.02 ± 490.01 and 3.04 ± 5.76 MPN/100 ml, respectively. Furthermore, the mean and SD of temperature, pH, electrical conductivity, chloride, and turbidity were 13.84 oC ± 5.62, 8.27 ± 0.45, 17.96 ± 6.56 µs/cm, 5776.95 ± 1996.38 mg/l and 27.48 ± 15.82 NTU, respectively. Statistical analysis showed that microbial qualities were affected significantly by physicochemical factors, but the roles of water temperature were more than others.
ConclusionThe microbiological results revealed that there was a remarkable level of contamination in some areas of Caspian sea. The results suggested that Clostridium perfringens provide better health risk prediction than other analyzed indicator bacteria, particularly in the warm season.

Air pollutants and respiratory diseases have a significant relationship and cause major health problems. Low attention has been paid to the daily hospital admissions due to the presence of pollutants in desert cities such as Yazd city, Iran. Therefore, this study aimed to investigate the short-term relationship between air pollution and daily hospital admissions due to respiratory disease in Yazd hospitals.
Materials and MethodsThis cross-sectional study investigated pollutants including PM10, CO, SO2, NO2, and O3 recorded daily in Yazd air pollution monitoring station. Moreover, the daily hospital admissions (sample size =180) of the pulmonary patients were collected from government hospitals from March to September 2017.
ResultsThe results showed that PM10 concentrations were higher than the Environmental Protection Agency (EPA) and World Health Organization standards. Furthermore, only 7.6% of the patients' diseases were attributed to air pollution. The highest correlation (R = 0.595 and P = 0.002) was observed between daily hospital admissions and NO2 concentration. However, after age adjustment in regression analysis, this relationship was also significant for O3. The behavior and variations of pollutants were interpreted by time series using auto-regressive moving average (ARMA) (1,1). The results showed that the best correlation was found between pollutants and admission of the patients at lag = 48 hr.
ConclusionThe daily admission of patients to hospital due to pulmonary disease was highly related to NO2 and O3. However, the correlation of admission with CO, PM10, and SO2 was not significant, because NO2 and O3 are oxidation factors and stimulate the respiratory system.
