The Nutri­tional Genomics focuses on the interaction between bioactive food components and the genome, which includes Nutrigenet­ics and Nutrigenomics. The influence of nutrients on f genes expression is called Nutrigenomics, while the heterogene­ous response of gene variants to nutrients, dietary components and developing nutraceticals is called Nutrigenet­ics. Genetic variation is known to affect food tolerances among human subpopulations and may also influence dietary require­ments and raising the possibility of individualizing nutritional intake for optimal health and disease prevention on the ba­sis of an individual's genome. Nutrigenomics provides a genetic understanding for how common dietary components af­fect the balance between health and disease by altering the expression and/or structure of an individual's genetic makeup. Nutrige­netics describes that the genetic profile have impact on the response of body to bioactive food components by influenc­ing their absorption, metabolism, and site of action. In this way, considering different aspects of gene-nutrient interac­tion and designing appropriate diet for every specific genotype that optimize individual health, diagnosis and nutri­tional treatment of genome instability, we could prevent and control conversion of healthy phenotype to diseases. https://ijph.tums.ac.ir/index.php/ijph/article/view/3076 https://ijph.tums.ac.ir/index.php/ijph/article/download/3076/2875

The purpopse of  the study was to develop a qualitative dynamic attribute value model which provides insight into the customers' value for healthcare institute managers by conducting the initial open-ended questionnaire survey to select participants purposefully. Methods: A total number of 427 questionnaires was conducted in two hospitals in Taiwan (one district hospital with 635 beds and one academic hospital with 2495 beds) and 419 questionnaires were received in nine weeks. Then, apply qualitative in-depth interviews to explore customers' perspective of values for building a model of partial differential equations. Results: This study concludes nine categories of value, including cost, equipment, physician background, physicain care, environment, timing arrangement, relationship, brand image and additional value, to construct objective network for customer value and qualitative dynamic attribute value model where the network shows the value process of loyalty development via its effect on customer satisfaction, customer relationship, customer loyalty and healthcare service. Conclusion: One set predicts the customer relationship based on comminent, including service quality, communication and em­pahty. As the same time, customer loyalty based on trust, involves buzz marketing, brand and image.  Customer value of the current instance is useful for traversing original customer attributes and identifing customers on different service share. https://ijph.tums.ac.ir/index.php/ijph/article/view/3077 https://ijph.tums.ac.ir/index.php/ijph/article/download/3077/2876

Many studies have been published so far concerning the occupational exposure of industrial workers, embalmers, pathologists and anatomists to FA but very few data regarding medical examiners are available. Methods: To assess the extent to which subjects were exposed to FA, airborne concentrations of this chemical were measured by High Performance Liquid Chromatography (HPLC). In September-October 2006 we examined the person­nel, which worked in an autopsy room (medical examiners) and in three laboratories of pathologic anatomy of the Uni­versity Medical School of Bari, Policlinico Hospital, Southern Italy. Irritative effects were also investigated. Results: All the personal exposure data obtained exceeded the National Institute for Occupational Safety and Health Threshold Limit Value-Time Weighted Average (NIOSH TLV-TWA: 0.02 mg/m3) and, in a few cases, even the Ameri­can Conference of Industrial Hygienists Threshold Limit Value-Ceiling level (ACGIH TLV-C: 0.37 mg/m3). Conclusion: Irritative effects in more than 50% of the workers enrolled, increasing the risk of injuries.   https://ijph.tums.ac.ir/index.php/ijph/article/view/3078 https://ijph.tums.ac.ir/index.php/ijph/article/download/3078/2877

Many species of the genus produce mycotoxins, which are responsible for acute or chronic diseases in ani­mals and humans. Identification of Fusaria to the species level is necessary for biological, epidemiological, pathologi­cal, and toxicological purposes. In this study, we undertook a computer-based analysis of ITS1-5.8SrDNA-ITS2 in 192 GenBank sequences from 36 Fusarium species to achieve data for establishing a molecular method for spe­cie-specific identification. Methods: Sequence data and 610 restriction enzymes were analyzed for choosing RFLP profiles, and subsequently de­signed and validated a PCR-restriction enzyme system for identification and typing of species.  DNA extracted from 32 refer­ence strains of 16 species were amplified using ITS1 and ITS4 universal primers followed by sequencing and restric­tion enzyme digestion of PCR products. Results: The following 3 restriction enzymes TasI, ItaI and CfoI provide the best discriminatory power. Using ITS1 and ITS4 primers a product of approximately 550bp was observed for all Fusarium strains, as expected regarding the se­quence analyses. After RFLP of the PCR products, some species were definitely identified by the method and some strains had different patterns in same species. Conclusion: Our profile has potential not only for identification of species, but also for genotyping of strains. On the other hand, some Fusarium species were 100% identical in their ITS-5.8SrDNA-ITS2 sequences, therefore differentia­tion of these species is impossible regarding this target alone. ITS-PCR-RFLP method might be useful for preliminary differ­entiation and typing of most common Fusarium species. https://ijph.tums.ac.ir/index.php/ijph/article/view/3079 https://ijph.tums.ac.ir/index.php/ijph/article/download/3079/2878

The aim of this study was to evaluate a PCR-based assay for specific and rapid detection of N. meninigitidis in CSF specimens.  Methods: Since April 2002 to July 2006, 130 CSF specimens were collected from patients suspected of having bacterial meningitis. Bacterial isolation and identification was carried out according to the standard bacteriological methods.  The PCR was used to amplify a 101bp fragment of capsular transport gene A (ctrA) of N. meningitidis. Results: PCR yielded an amplified product with the expected size of 101 base pair fragment. Sensitivity test proved 500 ng of N. meningitidis DNA as the final detection limit and specificity test revealed no cross-reaction for a wide range of res­pira­tory pathogenic organisms. Conclusion: The PCR assay was more sensitive than the bacterial culturing. It might be possible to apply this procedure for rapid diagnosis of meningococci in clinical samples. https://ijph.tums.ac.ir/index.php/ijph/article/view/3080 https://ijph.tums.ac.ir/index.php/ijph/article/download/3080/2879

MARS is a new non-parametric method in use in the literature for parameter estimations of cause and effect based research. MARS can both obtain legible model curves and make unbiased parametric predictions. Methods: In order to examine the performance of MARS, MARS findings will be compared to Classification and Regres­sion Tree (C&RT) findings, which are considered in the literature to be efficient in revealing correlations between variables. The data set for the study is taken from "The Internet Addiction Scale" (IAS), which attempts to reveal addiction levels of individu­als. The population of the study consists of 754 secondary school students (301 female, 443 male students with 10 miss­ing data). MARS 2.0 trial version is used for analysis by MARS method and C&RT analysis was done by SPSS. Results: MARS obtained six base functions of the model. As a common result of these six functions, regression equation of the model was found. Over the predicted variable, MARS showed that the predictors of daily Internet-use time on average, the purpose of Internet- use, grade of students and occupations of mothers had a significant effect (P< 0.05). In this compara­tive study, MARS obtained different findings from C&RT in dependency level prediction. Conclusion: The fact that MARS revealed extent to which the variable, which was considered significant, changes the charac­ter of the model was observed in this study. https://ijph.tums.ac.ir/index.php/ijph/article/view/3081 https://ijph.tums.ac.ir/index.php/ijph/article/download/3081/2880

Methods: We developed a single PCR method for this purpose.  After investigation of GenBank, primer pairs were de­signed from highly conserved regions of cysteine proteinase (CP5) gene. The primers were utilized in PCR using isolated ge­nomic DNA template of E. histolytica and the PCR products were then sequenced. The same primer and method for PCR was used for isolated genomic DNA template of E. dispar. Results: A fragment of about 950 bp was isolated in PCR by using DNA from E. histolytica, however, no banding pattern was produced by using the same primers for E. dispar. We characterized CP5 gene at molecular level in E. histolytica iso­lates from 22 positive; including 20 non-dysentery samples isolated from both cities as well as two dysentery samples iso­lated only from Tabriz. Nucleotide sequence comparison in gene data banks (NCBI, NIH) revealed significant homology with CP5 gene in E. histolytica isolates Conclusion: We developed a PCR method, which could detect simply and rapidly E. histolytica by amplifying a specific PCR fragment. https://ijph.tums.ac.ir/index.php/ijph/article/view/3082 https://ijph.tums.ac.ir/index.php/ijph/article/download/3082/2881

This study aimed to prove relationships between weather factors with considering human migration and previous case findings and malaria cases in endemic areas in Purworejo during 2005-2014. Methods: This study employed ecological time series analysis by using monthly data. The independent variables were the maximum temperature, minimum temperature, maximum humidity, minimum humidity, precipitation, human migration, and previous malaria cases, while the dependent variable was positive malaria cases. Three models of count data regression analysis i.e. Poisson model, quasi-Poisson model, and negative binomial model were applied to measure the relationship. The least Akaike Information Criteria (AIC) value was also performed to find the best model. Negative binomial regression analysis was considered as the best model. Results: The model showed that humidity (lag 2), precipitation (lag 3), precipitation (lag 12), migration (lag1) and previous malaria cases (lag 12) had a significant relationship with malaria cases. Conclusion: Weather, migration and previous malaria cases factors need to be considered as prominent indicators for the increase of malaria case projection.     https://ijph.tums.ac.ir/index.php/ijph/article/view/13144 https://ijph.tums.ac.ir/index.php/ijph/article/download/13144/5947

Methods: Overall, 128 adult patients with end-stage renal failure treated with MHD were collected in the Second Affiliated Hospital & Yuying Children’s Hospital of Wenzhou Medical University, Zhejiang Province, China in 2013. Serum sKlotho was detected by ELISA and coronary artery calcification was measured by multi-slice spiral computed tomography (MSCT). With 36 months' follow-up, death notes such as cause of death and death time were recorded. Results: Patients were divided into low sKlotho group and high sKlotho group. Age, blood phosphorus level, hypertension incidence and incidence of diabetes mellitus of the patients in low sKlotho group was significantly higher than that of high sKlotho group (P<0.05). The coronary artery calcification score (CACs) of patients in high sKlotho group was significantly lower than that of low sKlotho group (P<0.001). Logistic regression showed that the decrease of sKlotho level (P<0.001) was an independent risk factor for CAC progression. The mortality of the patients in low sKlotho group was higher than that of high sKlotho group. Kaplan-Meier survival curve had shown that survival time of the patients in low sKlotho group was significantly lower than that of high sKlotho group (P<0.05). Conclusion: SKlotho can increase the degree of CAC. Although MHD patients with low sKlotho level had shorter survival time, sKlotho is not an independent risk factor in prediction of prognosis of MHD patients.   https://ijph.tums.ac.ir/index.php/ijph/article/view/13145 https://ijph.tums.ac.ir/index.php/ijph/article/download/13145/5948

The incidence of colorectal cancer (CRC) in Taiwan is rising. We aimed to determine the five-yr survival rate of patients diagnosed with CRC and determine factors affecting survival. Methods: All patients were identified from the Taiwan Cancer Data Base of the Medical Center Hospital in North Taiwan from 2007 to 2013. Data were collected using medical records and the cancer database. In all, 869 patients with CRC were included. Survival analysis was performed using Kaplan-Meier curves, and differences between the curves were analyzed using the log-rank test. Cox proportional hazards regression models were used to analyze survival by each variable. Results: The five-yr survival rate and the mean survival time after cancer diagnosis were 68.7% and 71.27±1.27 months. Perineural nerve invasion, distant metastasis, age, pathological differentiation grade, obstruction and regional lymph node metastasis were found to be independent predictors of the survival and prognosis of patients with CRC. Conclusion: Perineural nerve invasion was an important factor related to the survival of CRC patients. Thus, the earlier detection of CRC might help improve survival.   https://ijph.tums.ac.ir/index.php/ijph/article/view/13146 https://ijph.tums.ac.ir/index.php/ijph/article/download/13146/5949

China Fang HUANG Special Ward 1, Shanghai Pulmonary Hospital, Shanghai 200082, P.R. China 2018 04 22 2018 04 22 Background: To investigate the effect of psychological intervention on nutrient status of perioperative patients with lung cancer. Methods: Overall, 176 lung cancer patients admitted to Shanghai Pulmonary Hospital, Shanghai China from 2015 to 2016 were divided into control group (n=88) and study group (n=88). Conventional nursing strategy was adopted for patients in control group, while psychological nursing strategy was implemented for those in the study group, and the specific nursing efficiency was compared between the two groups. In addition to the assessment with Symptom Checklist 90 (SCL-90) and Quality of Life Questionnaire-Core 36 (QLQ-C30), patients were required to fulfill the evaluations with nutrition risk screening 2002 (NRS2002) and Patient-Generated Subjective Global Assessment (PG-SGA). Results: After nursing care, significant amelioration in scores of SCL-90 and QLQ-C30 of patients were seen in the study group (P<0.05). In the study group, the scores of NRS2002 and PG-SGA were all lower than those in the control group (P<0.001). Besides, PG-SGA score was also significantly correlated with the levels of serum total proteins, serum albumin, hemoglobin, reduction in diet and weight (P<0.01), while only reduction in diet and weight was obviously correlated with the score of NRS2002 (P<0.01). Moreover, a significant correlation was identified between the scores of PG-SGA and NRS2002 (P<0.01). Conclusion: Psychological intervention could effectively alleviate the psychological stress response and ameliorate the nutrient status of lung cancer patients in perioperative period, thereby reducing the negative feelings and increasing the life quality of patients.   https://ijph.tums.ac.ir/index.php/ijph/article/view/13147 https://ijph.tums.ac.ir/index.php/ijph/article/download/13147/5950
