RESUMO
Vaginal lactobacilli protect against bacterial vaginosis and vaginal candidiasis. They may have probiotic properties and help maintain the balance and health of the vaginal ecosystem while the loss of these bacteria predisposes females to urinary and genital infections. The aim of this study was to investigate the probiotic potential of vaginal Lactobacillus among healthy females in northern Iran. The Lactobacillus strains were isolated from vaginal samples and were identified by sequencing of the 16S rRNA fragment. Functional properties such as tolerance to low pH, H2O2 production, adherence ability to Hela cells and antagonistic activity against Candida albicans was examined. A total of 38 vaginal lactobacilli strains from five species, including Lactobacillus crispatus (n = 13), Lactobacillus gasseri (n = 10), Lactobacillus acidophilus (n = 6), Lactobacillus jensenii (n = 5) and Lactobacillus johnsonii (n = 4), were identified. All of the species showed significant tolerance to low pH over 24 h (p < 0.001). The best adherence ability to Hela cells was seen in Lactobacillus gasseri strains. Nearly 17 of the strains had higher anti-candida activity compared to the other strains. According to the findings, four lactobacilli strains isolated in the vaginal samples of healthy Iranian women had the best probiotic potential.
RESUMO
Background and Objectives: This study assesses the antibiotic susceptibility of vaginal Lactobacillus strains and provides data for determining the prevalence of certain antibiotic resistance genes in the new strains of lactobacilli serving as probiotics and selected from healthy women in northern Iran. Materials and Methods: One hundred premenopausal non-pregnant women in the reproductive age range of 22-50 years participated in this study. The potential probiotic vaginal lactobacilli used in the study included Lactobacillus crispatus (34.2%), Lactobacillus gasseri (26.3%), Lactobacillus johnsonii (10.5%), Lactobacillus acidophilus (15.7%) and Lactobacillus jensenii (13.1%). The phenotypic antibiotic susceptibility of the strains was determined by E test and DNA extraction and PCR were performed to examine the antibiotic resistance genes. Results: 38 potential probiotic vaginal lactobacilli were isolated. All the strains of lactobacilli were resistant to metronidazole and trimethoprim/sulfamethoxazole and all of the strains were susceptible to ampicillin and chloramphenicol antibiotics. The results showed that ermB, ermC, and ermA genes were observed in the strains of Lactobacillus acidophilus. Metronidazole resistance (nim) gene was also found in one strain of Lactobacillus crispatus and Lactobacillus johnsonii. The aminoglycoside resistance (aac6'-aph2â³) gene was observed in 8% of the strains. Also, tetM, tetK and tetW genes were found in more than 80% of the Lactobacillus strains. Conclusion: The antimicrobial susceptibility of vaginal lactobacilli is an important criterion for establishing whether or not the organism is a probiotic. A high level of resistance to clinical antibiotics, such as metronidazole and aminoglycosides, was demonstrated. Antibiotic resistant genes also appeared widely in vaginal lactobacilli.
RESUMO
OBJECTIVES: Understanding patterns of quality of life in people who inject drugs (PWID) can help healthcare providers plan and manage their health problems in a more focused manner. Therefore, the current study aimed to identify patterns of health-related quality of life in PWID in southeast Iran. METHODS: This cross-sectional study was conducted in southeast Iran on men who had injected drugs at least once during the last year. We used convenience sampling in 2 drop-in centers and venue-based sampling at 85 venues. Demographic characteristics, high-risk behaviors, and health-related quality of life were evaluated using the 5-level EQ-5D version (EQ-5D-5L) questionnaire. Latent profile analysis was used to identify patterns of quality of life. RESULTS: This study enrolled 398 PWID, who had a mean age of 34.1±11.4 years. About 47.9% reported a prison history in the last 10 years, 59.2% had injected drugs in the last month, and 31.6% had a history of sharing syringes. About 46.3% reported having 2 or more sexual partners in the last 6 months, and 14.7% had a history of sex with men. Out of the 5 EQ-5D-5L profiles, the fifth profile had the most people (36.6%). Most variations in quality of life were related to pain and discomfort. CONCLUSIONS: We showed that the pain and discomfort dimension of EQ-5D-5L had more variation in PWID. This finding will be useful for allocating appropriate interventions and resources to promote health-related quality of life in this population.

PURPOSE: This research aims to establish a neutrophil-to-lymphocyte ratio (NLR) threshold and evaluate its diagnostic accuracy compared to pathological criteria for diagnosing Epithelial Ovarian Cancer (EOC). METHODS: We conducted a cross-sectional study at Imam Hossein Hospital involving 204 women aged 18 and older with confirmed ovarian mass based on pathology. We recorded clinical, pathological, and preoperative blood count data, including neutrophil-to-lymphocyte ratio (NLR). Patients were categorized into malignant and benign ovarian mass groups based on postoperative pathology. The power of NLR to diagnosis of EOC was evaluated using ROC curve. RESULTS: At total, 204 patients (Benign 75.5% vs. Malignant 24.5%) were included in the analysis with mean age of 54.26 ±12.04 yrs in malignant and 46.31±13.21 in benign. In all cases, the proportion of patients with the following tumor markers HE4 (>140 Pm), CA 125 (> 35U/Ml) and CEA (>5 ng/Ml) were 52.45%, 41.67% and 3.43%, respectively, and proportion of abnormal tumor markers was statistically higher in malignant group compared to benign mass (p <0.05). Odds of having higher NLR levels in the malignancy group was higher than benign group (e.g., OR of 4.45 for NLR in quartile 4 vs. quartile 1). According to model selection criteria, the full model with including NLR level and age, BMI and tumor markers has best performance for diagnosis of malignancy (AUC =0.87). CONCLUSION: High NLR in combination with tumor markers including CA125, HE4 and CEA were associated with malignancy in patients with ovarian mass. More attention and further examinations should be devoted for patients with ovarian mass having high NLR and abnormal tumor markers levels to detect the probable malignancy as soon as possible.

This study aimed to examine the impacts of single and multiple air pollutants (AP) on the severity of breast cancer (BC). Data of 1148 diagnosed BC cases (2008-2016) were obtained from the Cancer Research Center and private oncologist offices in Tehran, Iran. Ambient PM10, SO2, NO, NO2, NOX, benzene, toluene, ethylbenzene, m-xylene, p-xylene, o-xylene, and BTEX data were obtained from previously developed land use regression models. Associations between pollutants and stage of BC were assessed by multinomial logistic regression models. An increase of 10 µg/m3 in ethylbenzene, o-xylene, m-xylene, and 10 ppb of NO corresponded to 10.41 (95% CI 1.32-82.41), 4.07 (1.46-11.33), 2.89 (1.08-7.73) and 1.08 (1.00-1.15) increase in the odds of stage I versus non-invasive BC, respectively. Benzene (OR, odds ratio = 1.16, 95% CI 1.01-1.33) and o-xylene (OR = 1.18, 1.02-1.38) were associated with increased odds of incidence of BC stages III & IV versus non-invasive stages. BC stage I and stage III&IV in women living in low SES areas was associated with significantly higher levels of benzene, ethylbenzene, o-xylene, and m-xylene. The highest multiple-air-pollutants quartile was associated with a higher odds of stage I BC (OR = 3.16) in patients under 50 years old. This study provides evidence that exposure to AP is associated with increased BC stage at diagnosis, especially under premenopause age.

Background: COVID-19 pandemic has affected various aspects of human life. Bank employees who are more in contact with people are more likely to be infected during the pandemic situation. Moreover, mental, physical and social impacts of COVID-19 are more intense among these employees.Objective: this study aims to determine the effect of COVID-19 pandemic on bank employees' health and life satisfaction in Iran. Methods: This cross-sectional study was conducted during the fifth wave of COVID-19 from July to October 2021. The population included all the employees of Tejarat Bank in 20 provinces of Iran, 350 of whom were selected using the multi-stage cluster sampling method. The data were collected by demographic questionnaire, 12-item short-form (SF-12) personal health assessment survey and satisfaction with life scale (SWLS). The objective of the study was examined by the structural equation modeling (SEM). Results: The results showed the two default models of health function (CFI = 0.95) and life satisfaction (CFI = 0.99) had acceptable fit. Assessing the bank employees with COVID-19 revealed this disease had no direct impact on life satisfaction (ß = -0.05, P = 0.28) and health function (ß = 0.04, P = 0.48). However, it had a direct impact on physical function (ß = -0.18, P = 0.001) and, consequently, an indirect impact on life satisfaction. Moreover, low mental function reduced life satisfaction. Conclusion: COVID-19 infection had no direct impact on life satisfaction. However, it had an indirect and positive impact on it. Considering gender showed COVID-19 infection had a direct and positive impact on life satisfaction among women. The employees who recovered from COVID-19 infection reported higher life satisfaction after returning to work for various reasons than those who never got it.
RESUMO
OBJECTIVE: Leukaemia is one of the most common cancers and may be associated with exposure to environmental carcinogens, especially outdoor air pollutants. The objective of this study was to investigate the association of ambient air pollution and leukaemia in Tehran, Iran. DESIGN: In this retrospective cohort study, data about the residential district of leukaemia cases diagnosed from 2010 to 2016 were inquired from the Ministry of Health cancer database. Data from a previous study were used to determine long-term average exposure to different air pollutants in 22 districts of Tehran. Latent profile analysis (LPA) was used to classify pollutants in two exposure profiles. The association between air pollutants and leukaemia incidence was analysed by negative binomial regression. SETTING: Twenty-two districts of Tehran megacity. PARTICIPANTS: Patients with leukaemia. OUTCOME MEASURES: The outcome variables were incidence rate ratios (IRR) of acute myeloid and lymphoid leukaemia across the districts of Tehran. RESULTS: The districts with higher concentrations for all pollutants were near the city centre. The IRR was positive but non-significant for most of the air pollutants. However, annual mean NOx was directly and significantly associated with total leukaemia incidence in the fully adjusted model (IRR (95% CI): 1.03 (1.003 to 1.06) per 10 ppb increase). Based on LPA, districts with a higher multiple air-pollutants profile were also associated with higher leukaemia incidence (IRR (95% CI): 1.003 (0.99 to 1.007) per 1 ppb increase). CONCLUSIONS: Our study shows that districts with higher air pollution (nitrogen oxides and multipollutants) have higher incidence rates of leukaemia in Tehran, Iran. This study warrants conducting further research with individual human data and better control of confounding.

OBJECTIVE: Posttraumatic growth (PTG) is a positive psychological change after challenging life events. The purpose of this study was to investigate the effects of positive and long-term psychological changes in people who experienced the Bam earthquake. METHODS: A total of 916 adolescents were surveyed 17 years after the earthquake. Self-report questionnaires were administered to participants. A latent profile analysis (LPA) was conducted to extract the subgroups of adults. RESULTS: The LPA identified 5 meaningfully profiles that were characterized based on the pattern of PTG dimensions. The common profile was profile, which perceived very low "relating to others" dimension and medium for other PTG dimensions. Also, the results showed significant differences among gender and age and nonsignificant differences in marital status and education level among the profiles of PTG. CONCLUSIONS: For stressful situations, the different dimensions of PTG change indirectly in every person. In Bam, some patterns are seen according to PTG after 17 y. Among these dimensions, the part of "relating to others", has the greatest change. Another conclusion is that according to a relatively high profile for 5 clusters, it seems the impact of 17 y should be less on PTG as the number of extractive patterns is approximately high for the case.

BACKGROUND: Triple-negative breast cancer (TNBC) accounts for 15% of all breast cancer (BC) cases and is a severe type of BC. Since medicinal herbs containing biocompatible substances that are accepted by patient more than chemical therapeutics, they can be considered a safe option for treating BC. OBJECTIVE: This study evaluated the effect of Sambucus Ebulus (S. ebulus) extract on a model of TNBC. METHODS: S. ebulus extract was prepared using petroleum ether, ethyl acetate, and methanol. The petroleum ether extract was fractionated and analyzed using vacuum liquid chromatography and GC-MS, respectively. MDAMB- 231 and MCF-10A were used as TNBC and normal breast cells, respectively. Flowcytometry and MTT assays were performed to evaluate cell cycle, apoptosis, and viability of the cells. Gene expression analysis was performed using RT-qPCR. Nude mouse allograft tumor models were used, and pathological sections were evaluated. RESULTS: The findings indicated that S. ebulus extract remarkably decreased cell proliferation and viability. The extract had no toxicity to the normal breast cells but efficiently killed the cancer cells. Cell cycle- and apoptosisrelated gene expression showed that fraction 4 of S. ebulus extract significantly increased the expression of Bax, Bak, P53, and c-MYC. CONCLUSION: This study showed satisfactory results of the effect of S. ebulus extract on clearing BC cells both in vitro and in vivo. Thus, S. ebulus extract may be a safe herbal compound for eliminating BC cells without toxicity to host cells.

BACKGROUND: Traumatic events and psychological damage are common. Identifying different types of traumatic events contributes to the development of psychopathology and can be very helpful in macroeducational and treatment planners. The current study extracted the patterns (overlap) of different traumatic events that Iranian college students commonly experience, with the aim of understanding their association with posttraumatic growth (PTG) and religiosity. MATERIALS AND METHODS: Four hundred and sixty-six students from Kerman universities completed a cross-sectional survey about religion, and questions about PTG and traumatic events have experienced in the past 5 years. The latent class analysis (LCA) was used for extracting patterns of traumatic events, and the one-way ANOVA test was used to compare PTG and religiosity across these classes in Iranian college students. RESULTS: The LCA revealed that a three-class solution had an adequate relative and absolute fit. The three classes were labeled and characterized as multiple-traumatic events (2.9%), intermediate-traumatic events (31.1%), and low-traumatic events (66.0%). In ANOVA results for PTG and Duke University Religion Index (DUREL) domains across classes, individuals in the multiple-traumatic classes had the lowest score of PTG and DUREL domains. CONCLUSION: Although the current study showed the relative frequency of multiple-traumatic events in Iranian students is low, individuals categorized in this class had the lowest PTG, and these findings reveal the necessitation of planning and interventions for PTG.
RESUMO
Cadmium (Cd) is a widespread environmental pollutant. A number of observational studies have reported that Cd might be a cause of nasopharyngeal (NPC), pharyngeal (PC), or laryngeal cancers (LC). In this study evidence about the relation of Cd and NPC, PC, and LC has been summarized. A literature review was conducted until 20 June 2020 in PubMed, Ovid, Scopus, Web of Science and Google scholar databases to investigate the epidemiologic evidence for the relation between cadmium exposure and cancers of the nasopharynx, pharynx, and larynx. Ten articles were selected after careful screening of retrieved studies. All of these studies obtained a Newcastle-Ottawa Scale (NOS) quality score from 6 to 8. Due to high heterogeneity, in all analyses, random effect was used. The pooled results showed that cadmium levels in NPC (standard mean difference (SMD=0.55; 95% CI=0.20, 0.89; p=0.002) and PC (SMD=9.79; 95% CI=0.62, 18.96; p=0.036) patients/tissues were significantly higher than their controls. But cadmium levels were not significantly different between LC cases/tissues and their controls. (SMD=-0.05; 95% CI=-0.99, 0.89; p=0.921). Exposure to cadmium is likely to cause nasopharyngeal and pharyngeal cancer.

BACKGROUND: Despite the development of their prevention and treatment, infectious diseases cause high mortality, many disabilities and inadequate living conditions worldwide. The aim of this study was to evaluate the pattern of infectious diseases in northern Iran with an approach to internal medicine management. METHODS: This cross-sectional research was conducted in 2019 on all 7095 infectious diseases patient records that referred to Ghaemshahr Razi Hospital, Mazandaran Province, Iran during 2012-2018. A checklist prepared by investigator was used to collect the data. The extracted data were coded and entered into SPSS 22 and analyzed using K2 and independent t-test at p<.05. RESULTS: The mean age of the study patients was 29.7±26.4. 4372 (61%) of the cases were males and the mean duration of hospitalization was 41.6±33.5. Age was significantly correlated to infectious diseases (P=.001). Gastroenteritis was the most common infectious disease among the men and women with 2442 (60.5%) and 1594 (39.47%), respectively. Based on the Pearson's correlation test, the relationship between leptospirosis, brucellosis, pulmonary tuberculosis, shigellosis, sepsis and infectious mononucleosis with gender, habitation, admission mode, discharged mode and age was significant (p<.05). CONCLUSION: As the high frequent diseases were gastroenteritis, leptospirosis, brucellosis and sepsis and an increasing trend was in the prevalence of gastroenteritis, leptospirosis and lung tuberculosis, health system managers should consider training courses, preventive strategies, real-time interventions, increased hospital bed rate for patients with infectious diseases and so on.
RESUMO
Lung cancer is the most rapidly increasing malignancy worldwide with an estimated 2.1 million cancer cases in the latest, 2018 World Health Organization (WHO) report. The objective of this study was to investigate the association of air pollution and lung cancer, in Tehran, Iran. Residential area information of the latest registered lung cancer cases that were diagnosed between 2014 and 2016 (N = 1,850) were inquired from the population-based cancer registry of Tehran. Long-term average exposure to PM10, SO2, NO, NO2, NOX, benzene, toluene, ethylbenzene, m-xylene, p-xylene, o-xylene (BTEX), and BTEX in 22 districts of Tehran were estimated using land use regression models. Latent profile analysis (LPA) was used to generate multi-pollutant exposure profiles. Negative binomial regression analysis was used to examine the association between air pollutants and lung cancer incidence. The districts with higher concentrations for all pollutants were mostly in downtown and around the railway station. Districts with a higher concentration for NOx (IRR = 1.05, for each 10 unit increase in air pollutant), benzene (IRR = 3.86), toluene (IRR = 1.50), ethylbenzene (IRR = 5.16), p-xylene (IRR = 9.41), o-xylene (IRR = 7.93), m-xylene (IRR = 2.63) and TBTEX (IRR = 1.21) were significantly associated with higher lung cancer incidence. Districts with a higher multiple air-pollution profile were also associated with more lung cancer incidence (IRR = 1.01). Our study shows a positive association between air pollution and lung cancer incidence. This association was stronger for, respectively, p-xylene, o-xylene, ethylbenzene, benzene, m-xylene and toluene.

BACKGROUND: Early diagnosis and supportive treatments are essential to patients with coronavirus disease 2019 (COVID-19). Therefore, the current study aimed to determine different patterns of syndromic symptoms and sensitivity and specificity of each of them in the diagnosis of COVID-19 in suspected patients. STUDY DESIGN: Cross-sectional study . METHODS: In this study, the retrospective data of 1,539 patients suspected of COVID-19 were obtained from a local registry under the supervision of the officials at Shahroud University of Medical Sciences, Shahroud, Iran. A Latent Class Analysis (LCA) was carried out on syndromic symptoms, and the associations of some risk factors and latent subclasses were accessed using one-way analysis of variance and Chi-square test. RESULTS: The LCA indicated that there were three distinct subclasses of syndromic symptoms among the COVID-19 suspected patients. The age, former smoking status, and body mass index were associated with the categorization of individuals into different subclasses. In addition, the sensitivity and specificity of class 2 (labeled as "High probability of polymerase chain reaction [PCR]+") in the diagnosis of COVID-19 were 67.43% and 76.17%, respectively. Furthermore, the sensitivity and specificity of class 3 (labeled as "Moderate probability of PCR+") in the diagnosis of COVID-19 were 75.92% and 50.23%, respectively. CONCLUSION: The findings of the present study showed that syndromic symptoms, such as dry cough, dyspnea, myalgia, fatigue, and anorexia, might be helpful in the diagnosis of suspected COVID-19 patients.

Some studies have shown that exposure to polycyclic aromatic hydrocarbons (PAHs) is a dangerous factor for attention deficit hyperactivity disorder (ADHD). This systematic review and meta-analysis aimed to clarify this relationship, and to collect and analyze all the relevant evidences in published reports of epidemiologic studies. PubMed, Science Direct, Web of Science, Scopus, and Google Scholar databases were searched through September 31, 2018. The study quality was evaluated using the Newcastle-Ottawa Scale. Moreover, fixed- and random-effect models were used. The data in this meta-analysis were presented as adjusted odds ratio (AOR). From 959 articles, six articles were included in the systematic review, and for meta-analysis, one study (that was not AOR) was excluded. The participants included in the studies were 2799 with the age range of 5-15 years old, and 93.6% were living in America. Four of the studies were placed in one group, due to having a common author (Perera). Moreover, a significant association was found between PAH exposure and ADHD in these studies (odds ratio = 2.57, 95% CI = 1.75-3.78); however, in all studies, there was no significant association between PAH exposure and ADHD for children (overall odds ratio = 1.99, 95% CI = 0.96-4.11) with low heterogeneity (I2 = 28.73%; P value < 0.001). This study provided a systematic review and meta-analytic evidence for the association between PAH exposure and ADHD by a small number of studies. Further research study can be conducted in various countries. Graphical Abstract.

The prevalence of non-communicable diseases is increasing worldwide. Multimorbidity and long-term medical conditions is common among these patients. This study aimed to investigate the patterns of non-communicable disease multimorbidity and their risk factors at the individual and aggregated level. Data was inquired from the nationwide survey performed in 2011, according to the WHO stepwise approach on NCD risk factors. A latent class analysis on multimorbidity components (11 chronic diseases) was performed and the association of some individual and aggregated risk factors (urbanization) with the latent subclasses was accessed using multilevel multinomial logistic regression. Latent class analysis revealed four distinct subclasses of multimorbidity among the Iranian population (10069 participants). Musculoskeletal diseases and asthma classes were seen in both genders. In males, the odds of membership in the diabetes class was 41% less by increasing physical activity; but with increased BMI, the odds of membership in the diabetes class was 1.90 times higher. Tobacco smoking increased the odds of membership in the musculoskeletal diseases class, 1.37 and 2.30 times for males and females, respectively. Increased BMI and low education increased the chances of females' membership in all subclasses of multimorbidity. At the province level, with increase in urbanization, the odds of membership in the diabetes class was 1.28 times higher among males (P = 0.027). Increased age, higher BMI, tobacco smoking and low education are the most important risk factors associated with NCD multimorbidity among Iranians. Interventions and policies should be implemented to control these risk factors.

BACKGROUND: Bullying in school-age children is a public health concern that less discusses in Middle East countries like Iran. The goal of this study was to determine and compare whether exposure to various forms of bullying behaviors contributes to disparities in life satisfaction and self-rated health among Iranian pupils. STUDY DESIGN: A cross-sectional study. METHODS: Data were obtained from a cross-sectional study on 834, 8th and 9th-grade students conducted in northern Iran in 2014. Bullying was measured by the Iranian-version of the Olweus Bullying Questionnaire. Life satisfaction and self-rated health were assessed by a single item of the Global School Health Survey (GSHS) in Persian. Descriptive statistics and two-level logistic regression analysis were used for data analysis. RESULTS: Positive self-rated health and life satisfaction were significantly higher in boys than girls (P<0.002). Self-related health and life satisfaction were similar in the 8th and 9th-grade students. After controlling for gender and grade, students involved in only-victim of verbal bullying (OR=0.48, 95% CI: 0.34, 0.67), and bully-victim of relational bullying (OR=0.29, 95% CI: 0.12, 0.67) reported lower self-rated health compared to non-involved students. CONCLUSION: Life satisfaction and self-rated health were differently related to types of bullying behaviors. Our findings highlighted the necessity to detect victims and bully-victims and develop prevention programs to stop bullying and its negative consequences in Iranian schools.

BACKGROUND: The objective of this study was to compare various lipid ratios for detection of metabolic syndrome (MetS) in the Iranian general population. METHODS: This cross-sectional study involved 5677 subjects aged ≥18 years from the general population in Kerman, Iran. Associations between lipid ratio quartiles and MetS were analyzed using logistic regression models. The areas under receiver operating characteristic (ROC) was calculated to determine the accuracy of lipid ratios in predicting MetS. RESULTS: The adjusted chance of having MetS across quartiles of all lipid ratios had an increasing significant pattern (P < 0.0001). The area under the curves of triglyceride/high-density-lipoprotein-cholesterol (TG/HDL-C) ratio was 0.85 (95% CI = 0.84-0.87) in men and 0.85 (95% CI = 0.84-0.86) in women, of total cholesterol (TC)/HDL-C ratio was 0.79 (95% CI = 0.77-0.81) in men and 0.79 (95% CI = 0.77-0.81) in women and of low-density-lipoprotein cholesterol (LDL-C)/HDL-C ratio was 0.73 (95% CI = 0.71-0.75) in men and 0.74 (95% CI = 0.72-0.76) in women. CONCLUSION: Our results indicate that the TG/HDL-C Ratio is a better marker than the LDL-C/HDL-C ratio and the TC/HDL-C ratio for identifying MetS in the Iranian population and could be used in clinical practice.

BACKGROUND: Cystic echinococcosis (CE) is a zoonotic disease with global prevalence, which causes considerable health problems and economic losses throughout the world. The aim of this study was to assess the seroepidemiology of CE in Doroud City, Lorestan Province, Iran, considered a neglected endemic location. METHODS: An ELISA was performed using recombinant AgB from Apr to Jul 2015 in Lorestan Province, Western Iran. The commercial Hydatidosis IgG ELISA kit (Vircell SL, Granada, Spain) was used to confirm the obtained results. RESULTS: In the present study, out of 927 collected sera, 25 samples (2.6%) were found as seropositive for E. granulosus IgG antibodies. The prevalence of IgG antibodies against E. granulosus was significantly higher in rural areas (3.24%) than in urban area (1.20%) (P<0.001). Moreover, there was no significant relationship between age, occupation, sex, and literacy with seropositivity (P>0.05). Moreover, there was no statistically significant difference between the prevalence of CE in males (13/349, 3.72%) and females (12/553, 2.12%). With regard to occupation, farmers and ranchmen had the highest rate of infection (5.5%). There was a significant association between eating unwashed vegetables and seropositivity (P<0.001). Seropositive cases in rural areas were more than in urban areas. CONCLUSION: Since all the seropositive cases used unwashed local vegetables, the contamination may occur through the consumption of such vegetables.
