Abstract
Background and Aim: Nowadays, because of the intense competition between nutrition consultants and rapid changes in patients' demands for nutrition counseling, application of the concepts such as "Entrepreneurial Opportunities Recognition" in this field seems unavoidable. One of the most commonly used methods for recognition of entrepreneurial opportunities is "Strategic Analysis of External Environment". Present survey has been conducted in order to study the impact of nutrition consultants' educational level on their strategic analysis about entrepreneurial opportunities.
Materials and Methods: This analytical survey was implemented based on the data (nutrition consultants' educational levels and their responses regarding the supply and demand for nutrition counseling services) which was collected during a previous study entitled ((Analysis of supply and demand trends in the field of diabetes nutrition counseling: A basic step towards identifying the entrepreneurial opportunities for nutrition consultants)). Also, ((Spearman's correlation test)) and ((GLM multivariate test)) were performed for the analysis of aforementioned data.
Results: Both statistical tests showed that nutrition consultants' educational levels (including 1- Bachelor of Science and 2- Master of Science and PhD) had significant relationship with two-thirds of their comments.
Conclusion: Nutrition consultants' educational level has a relative impact on their strategic analysis about the entrepreneurial opportunities.

Abstract
Background and Aim: Onychomycosis or nail fungus infection has an increasing prevalence with many effects on patients’ social life and mental health dermatophytes, yeasts and non-dermatophyte molds are among the best known agents of fungal infections of nails. The purpose of this study was to determine the prevalence of non-dermatophyte molds using morphological (direct examination and culture) and molecular (PCR) methods in patients referring to Medical Sciences Mycology Laboratory in Tehran, Iran.
Materials and Methods: In this study, samples were taken from 170 patients. For direct microscopic examination (DME), 15% KOH solution was used for the culture of samples, Sabouraud dextrose agar media (S) was applied together with chloramphenicol (SC) and chloramphenicol and cycloheximide (SCC). Meanwhile, differential tests were done for mycological diagnosis (slide culture), and 28SrDNA amplification and sequencing were performed for suspect or unknown samples.
Results: Of the 170 patients, 74 cases (43.5%) had onychomycosis, of which 53 cases (71.62%) were female and 21 cases (28.38%) were male. Also, of the 74 cases of onychomycosis, 40 cases (54.05%) were reported candidiasis, 21 cases (28.37%) non-dermatophyte molds, and 12 cases (16.21 %) dermatophytes.
Conclusion: The prevalence of onychomycosis in this study was 43.5% and the application of polymerase chain reaction (PCR) technique in cases of false positive, false negative and long-term culture was valuable meanwhile, given that all the samples that had positive results in DME with negative cultures were positive in molecular tests, this study reveals the power of molecular techniques compared with culture method.

Abstract
Background and Aim: Different regulation processes have an effect on osteoblastic differentiation of mesenchymal stem cells (MSCs), and among them Wnt signaling pathway is particularly desirable. In Wnt signaling pathway, Adenomatous Polyposis Coli (APC) bind to β-catenin and induce its degradation, thereby acting as a negative regulator of canonical Wnt pathway. In this study, gene expression and DNA methylation of APC gene during osteoblastic differentiation were determined.
Materials and Methods: In this experimental study, after the isolation of MSCs, the induction of osteoblastic differentiation was done. To confirm osteoblastic differentiation, alizarin red staining together with the expression of Alkaline Phosphatase (ALP) and osteocalcin as specific osteoblastic markers was performed. APC gene methylation status by MSP (Methylation Specific PCR) and gene expression status of APC gene using Real-Time PCR technique during different times were evaluated.
Results: The results of alizarin red staining and the expression of ALP and osteocalcin confirmed osteoblastic differentiation. In addition, the results showed a significant decrease in the expression of APC gene on the 7th day of osteoblastic differentiation (P<0.05). Also, the results revealed hypermethylation status of APC gene promoter during osteoblastic differentiation.
Conclusion: It seems that the decreased expression APC gene will play an important role in Wnt signaling pathway regulation in different stages during osteoblastic differentiation of bone marrow-derived MSC. Also, according to the results, APC gene promoter methylation will play an important role in controlling gene expression.

Abstract
Background and Aim: Giardiasis is the most common pathogenic gastrointestinal parasite worldwide and transmitted by ingesting parasite cyst, through water and food and person-to-person contact. Therefore in food handlers and child care workers it is of high importance. In this study we surveyed the job of individuals with giardiasis.
Materials and Methods: This study was a pilot descriptive-analytic study. Hundred and nine stool samples were collected from individuals referred to medical centers affiliated to Tehran University of Medical Sciences for health certificate.
Samples were examined with wet mount smear and formol-ether concentration methods. Also a questionnaire was given to each individual.
Results: Sixty nine samples were infected with Giardia lamblia. among positive samples for Giardia lamblia 25 (36.23%) were related to food handlers and occupations which are most frequently associated with food, one (1.44%) nurse, one (1.44%) managing director of the nursery, two (2.89%) housekeepers and one servant (1.44%).
Conclusion: Person-to-person Giardia lamblia transmission is often associated with poor hygiene and sanitation, most commonly by food handlers.
Also, day- care workers have a higher risk of infecting children attending day-care centers. Therefore particular attention should be paid to health of this workers as well as three times stool examination.

Abstract
Background and Aim: Currently, utilizing different nutritional indicators to investigate the association between diet and various diseases is considered in previous studies, which is related with some chronic diseases. However, no studies have studied the connection between the indicators with the rate of metabolism at rest (RMR). Therefore, the present study aimed to determine the relationship between dietary index and insulin load with resting metabolic rate (RMR) in overweight and obese women
Materials and Methods: A total of 280 healthy overweight and obese women (aged 18-50 years) who were referred to community health centers of Tehran University of medical sciences were included. In this study anthropometrics measurements such as weight, height, waist circumference, waist to hip ratio, body mass index, fat percentage, and fat-free mass were evaluated for every participant. Data on dietary intakes were collected using 147 semi-quantitative food frequency questionnaire (FFQ). DII and DIL were calculated using food insulin index values published earlier. To assess the RMR, indirect calorimetry was used.
Results: Mean age of study participants was 36.4±8.38 years. Although a significant association was seen between DII and RMR in a crude model (P=0.04); adjusting for different confounders made this significant relationship between DII and RMR insignificant. In addition, the dietary insulin index had no significant relationship with the amount of RMR/kg (p=0.63) and RMR/FFM (p=0.73).
Conclusions: Based on the results of this cross-sectional study, it seems that the insulin index and insulin load of the diet are not associated to the rate of resting metabolism. However, due to the limitations of this study, findings can only confirm or reject the hypothesis under further studies. It is also necessary to determine the role of dietary insulin indicators on human health, especially with a Study Prospective Design

Abstract
Background and Aim: Denture stomatitis is the most prevalent oral mucosal lesion among denture wearers. Because there have been multiple reports of resistance of Candida species to antifungal drugs in the last two decades, if the antifungal properties of Achillea millefolium and Trachyspermum ammi are validated, these compounds may be a suitable adjuvant drug along with the use of common antifungal drugs. Therefore, the current study aimed to assess the antifungal activity of alcoholic extracts of Achillea millefolium and Trachyspermum ammi against Candida albicans isolated from denture stomatitis.
Materials and Methods: Antifungal sensitivity of 50 isolates of C. albicans with the origin of denture stomatitis to the alcoholic extracts of Achillea millefolium and Trachyspermum ammi plants as well as the antifungal drugs miconazole and nystatin was determined by broth microdilution method and according to CLSI-M27S4 guidelines. The range of dilution for all compounds was 0.016-16 μg/ml. A concentration of compounds that showed at least 50% growth inhibition as compared to the positive control group was considered MIC (minimum growth inhibitory concentration). Statistical analysis was done using SPSS software and the significance level was considered as P<0.05.
Results: The MIC ranges in microbroth dilution method for the antifungal drugs miconazole, nystatin, as well as the alcoholic extracts of Achillea millefolium and Trachyspermum ammi plants on C. albicans, were close to each other, indicating that their effectiveness against C. albicans species does not differ significantly (P<0.05). The Achillea millefolium methanolic extract had the highest and lowest MIC values, with an average of 2.67±2.55 μg/ml and 0.067±0.057 μg/ml, respectively. A significant difference (P<0.001) was observed when the MICs outcomes the herbal alcoholic extracts and antifungal drugs were compared.
Conclusion: Based on the obtained MICs, Achillea millefolium and Trachyspermum ammi alcoholic plant extracts have a lesser efficacy than the antifungal drugs, but even though they may have a lower MIC and more effectiveness than other chemical drugs.

Abstract
Background and Aim: All people living in a society are not equally at risk of COVID-19 infection and hospitalization. The current study is aimed to determine the factors related to COVID-19 infection and hospitalization among participants of Ravansar Non-Communicable Disease (RaNCD) cohort study.
Materials and Methods: The present study was conducted between 28th February, 2020 to 27th November, 2021. Data from the RaNCD study, morbidity and hospitalizations cases (extracted from the medical care monitoring system, SAMA system and the handwritten list of the health department) and positive serological results were used. For the case-cohort study, 626 confirmed and/or probable cases and 2107 randomly selected participants as sub-cohort were recruited. For the case-control study, 188 COVID-19 hospitalized patients from RaNCD (as cases) and 632 positive outpatients identified as controls. Data were analyzed using Cox and logistic regression, respectively.
Results: In case-cohort study, the hazard ratio of COVID-19 among people living in rural areas, in smokers and those in middle socioeconomic status was, 0.37 (0.24, 0.58), 1.50 (1.07, 2.11), as compared to the reference groups. While the hazard ratio of people aged 46-64 and those ≥65 years old, as compared to the reference group within the first year, was 3.47 (1.76, 6.86) and 6.45 (2.80, 14.85), the corresponding value after one year was 2.23 (1.13, 4.40) and 3.52 (1.53, 8.10), respectively. The hazard ratio among those with at least one comorbidity was 2.45 (1.53, 3.92) in the first year of study and after one year decreased to 1.82 (1.14, 2.92). In addition, moderate and vigorous physical activity decreased the hazard ratio. In case-control study the odds ratio of hospitalization increased by 0.03% (1.03(1.01, 1.05)) with an increase of one year in age and in people with at least three comorbidities was 2.43 (1.24, 4.73) times of those without comorbidity.
Conclusion: Overall, one year after starting the study the decrease in hazard ratio of COVID-19 was significant. Increase in age and having comorbidities are factors that increased the odds ratio of hospitalization. Such people can be considered for the next waves of COVID-19 prioritized for health care and booster vaccination.

Abstract
Background and Aim: As a result of the COVID-19 pandemic, the global and Iranian economies have been affected in various ways. The tax sector seems to have reacted relatively quickly to this pandemic. This study examined the impact of the COVID-19 pandemic on tax revenues in West Azerbaijan Province.
Materials and Methods: This descriptive-analytic and cross-sectional study was conducted in the second half of 2021. Primary data for 17 cities of West Azerbaijan Province were provided by the General Administration of Tax Affairs of this province in the form of 9 variables in Excel Format. The data were related to 2019 (Before the COVID-19 pandemic) and 2020 (After the COVID-19 pandemic). The data were analyzed by SPSS using descriptive statistics (Frequency, Percentage, Median, Interquartile range) and analytical statistics (Wilcoxon signed rank test) at a 5% significance level.
Results: Based on the descriptive results, the COVID-19 pandemic caused an increase in the tax revenues of West Azerbaijan province in the fields of government employees’ salary tax, stock transfer tax, inheritance tax and stamp duty tax and a decrease in these revenues in the areas of private employee’s salary tax, income tax on legal entities, business income tax, property transfer tax and value-added tax. Based on the analytical results, the impact of this pandemic on the private employee’s salary tax (P=0.003), income tax on legal entities (P=0.019), business income tax (P=0.013), property transfer tax (P=0.015) and value-added tax (P=0.001) was found to be negative and significant. Furthermore, the effect on stock transfer tax (P=0.030) and inheritance tax (P=0.001) was positive and significant. On the other hand, the impact of this pandemic on government employees’ salary tax (P=0.287) and stamp duty tax (P=0.356) was not statistically significant.
Conclusion: The COVID-19 pandemic hurt most of the tax revenue sectors. To compensate for the decreased income in vulnerable sectors, the government must develop international trade with comprehensive support from the non-governmental sector while creating new tax lines. Also, stabilizing the financing cycle and designing mechanisms to prevent tax evasion, especially in high-paying jobs, can be fruitful.

Abstract
Background and Aim: Children’s health is important as the future builders of society. Many children under 5 years of age around the world and in Iran have growth disorders. Due to the importance of growth disorder and its impact on the development, learning and future of the child, the present study was conducted with the aim of determining the frequency of deviations from the growth curves of children under 5 years of age and related factors in Zahedan city.
Materials and Methods: This case-control study was conducted in 2020 in Zahedan. The study population included all children under 5 years old, born in Zahedan between 2013 and 2020 that 784 of whom were selected by random sampling method. To determine the factors related to growth disorder multiple logistic regression analysis was used and to check the significance level, chi-square test and Pearson correlation were used. In this research, the data were analyzed with SPSS software.
Results: The results of this research showed that 54% of the boys and 51.20% of the girls had growth disorders. Between child growth disorder and maternal chronic disease (P<0.05), maternal body mass index (P<0.05), Maternal weight gain during pregnancy (P<0.05), distance between births (P<0.05) maternal urinary tract infection during pregnancy (P<0.05), mother’s age (P=0.006), mother’s education (P<0.05), birth weight (P<0.001), birth order (P<0.05), father’s occupation (P<0.05) and father’s education (P<0.05) a significant association was found. In the present study, the average birth weight in children with growth disorders was 2.75±0.58 and in healthy children was 2.95±0.57, and this difference was statistically significant (P=0.001). The average age of mothers of children with growth disorders was 29.19±6.07 and the average age of mothers of healthy children was 27.98±6.10, this difference was statistically significant (P=0.006).
Conclusion: Growth disorder is a multi-causal complication. Risk factors can be corrected and prevented by developing health education and increasing mothers’ awareness and knowledge. Also, the father’s job and literacy are effective in the child’s growth disorder, so Increasing community health literacy and encouraging fathers’ learning and literacy can partially prevent growth disorders in children.

Abstract
Background and aim: This study aimed to determine the position of Iran in terms of scientific publications in Immunology and Microbiology, and also to identify the general status of science production and the patterns of publishing in the world, the Middle East, and Iran, analyze Iran scientific collaboration with the Middle East and the world, and explore the relationship between these indicators.
Materials and Methods: The study population contained 30622 Middle Eastern publications in Immunology and Microbiology from 2009 to 2018. Positioning the countries and exploring the relations of indicators, the exploratory factor analysis, and the correlation matrix were conducted using Scival.
Results: According to the findings Iran, Turkey, and Saudi Arabia were among the most powerful countries in the region in terms of publication, citation, regional, international, and overall scientific collaboration. As for regional positioning, the citations had the highest weight comparing to other indicators. Iran have the first rank in the indices of scientific production and citations with 43.63% and 33.76% respectively, third rank in the regional cooperation index with 43.63%, second rank in the extra-regional cooperation index with 23.56%, and also second rank in the total cooperation index with 22.12%.
Conclusion: The indicators were strongly connected togather; however, the citations and international scientific collaborations displayed the strongest amongst others. Despite Iran’s prominent position in both fields, the quality of the publication was lower than the regional and global average. This identified the most powerful and weak countries in the region in regards to scientific capacities in Immunology and Microbiology. Moreover, it reckoned that there was a strong relation between citations and scientific production in contrast with others.
