Etiology, consequences, and solutions of working women's work-life conflict: a qualitative study.

INTRODUCTION: Work-life conflict (WLC) is important in organizational behavior research and human resource management. The present research aimed to investigate the underlying causes, consequences, and solutions to WLC in Iranian working women. MATERIALS AND METHODS: The present qualitative study was conducted through a content analysis method among 19 working married women in Birjand, a city in the east of Iran, from December 2021 to February 2022. To collect the data, semi-structured interviews were held. The average interview time was 45 minutes, and all interviews were recorded upon the participants' consent. Finally, after coding, the information was analyzed with MAXQDA software. FINDINGS: The causes of conflict included 4 main categories of individual, interpersonal, organizational, and cultural factors, with seven subcategories: the pressure of the mother's role at home, personality traits, lack of individual skills, insufficient support, work characteristics, organizational policies, and the traditional role of women in society. The consequences of conflict included 2 main categories, Decreasing quality of life and work problems with 4 subcategories: physical and mental illnesses, forgetting one's role towards others, limiting social communication, and reducing productivity. Conflict resolution methods included 3 main classes of individual-oriented, other-oriented, and organization-oriented with 8 subclasses: program-oriented, meaning-oriented, emotion-oriented, avoidance, emotional support, instrumental and work support, support work policies, and correct management views. CONCLUSION: To solve the problem of conflict, different aspects should be considered and help to solve this challenge by influencing each dimension.

Expression of the Hepatitis C Virus core-NS3 Fusion Protein on the Surface of Bacterial Ghosts: Prospects for Vaccine Production.

Background: Antigen presentation using bacterial surface display systems, on one hand, has the benefits of bacterial carriers, including low-cost production and ease of manipulation. On the other hand, the bacteria can help in stimulating the immune system as an adjuvant. For example, using bacterial surface display technology, we developed a hepatitis C virus (HCV) multiple antigens displaying bacteria's surface and then turned it into a bacterial ghost. Methods: The HCV core and NS3 proteins' conserved epitopes were cloned into the AIDA gene plasmid as an auto transporter. The recombinant plasmid was then transformed into Escherichia coli (E. coli) Bl21 (DE3). Recombinant bacteria were then turned into a bacterial ghost, an empty cell envelope. Whole-cell ELISA, flow cytometry, and Western blot techniques were used for monitoring the expression of proteins on the surface of bacteria. Results: A fusion protein of HCV core-NS3-AIDA was successfully expressed on the E. coli Bl21 (DE3) surface and confirmed by western blotting, Enzyme-Linked Immunosorbent Assay (ELISA), and flow cytometry detection techniques. Conclusion: The presence of HCV antigens on non-pathogen bacteria surfaces holds promise for developing safe and cost-benefit-accessible vaccines with optimal intrinsic adjuvant effects and exposure of heterologous antigens to the immune system.

Improving the mental health of working women with work-life conflict: A protocol development for an explanatory mixed method study.

BACKGROUND: Today, one problem facing working women is the conflict between work and life, and the resultant stress has a great impact on their mental health. A well-known model for stress management is Lazarus and Folkman's model. The primary goal of the present study is to improve working women's mental health through stress management. MATERIALS AND METHODS: The present study employs a mixed approach and is conducted in 4 phases. The target population is women working in Birjand University (South Khorasan province/Eastern Iran). The first step is to describe the research population of a cross-sectional study. The measurement instrument used is Carlson's standard work-life conflict measurement questionnaire. The sample size in this step is 319. The second step is to conduct a qualitative study by interviewing working women with work and life conflict. The sampling will continue until data saturation and then the data will be analyzed through a content analysis. The third step will be the development of a questionnaire based on Lazarus and Folkman's model using the information obtained from the qualitative step. This questionnaire will be then validated in the target research population. Moreover, an exploratory factor analysis, a confirmatory factor analysis and a reliability test will be run. The last step is to carry out an educational intervention to measure the effect of the intervention on stress management and general health in working women with work and life conflict. The measurement instruments used in this step are Cohen's Perceived Stress Questionnaire, General Health Questionnaire, and a researcher-made stress management questionnaire. CONCLUSION: It seems that the educational intervention of stress management with educational content designed based on the needs of the audience, can be effective in controlling and managing the stress caused by women's work-life conflict.

Investigation of job satisfaction amongst voluntary, counseling and testing centers and health centers in Iran.

BACKGROUND: Job satisfaction is the persons' feeling about their job and if personnel have not good feel to his work, can destroy all plans, intentionally or unintentionally. The present research aims to investigate and compare job satisfaction in the employees and therapists of Voluntary, Counseling and Testing Centers versus Health centers in 9 provinces of Iran. METHODS: All employees of Voluntary, Counseling and Testing Centers were included from Fars, Bushehr, Tehran, Isfahan, South Khorasan, Kurdistan, Kermanshah, Kerman, and Yazd provinces as case group and 103 staffs of similar Health centers selected with the same ratio as the staffs of Voluntary, Counseling and Testing Centers as control samples and answered to Minnesota Satisfaction Questionnaire (MSQ). RESULTS: 50.5% of Health centers employees and 54% of Voluntary, Counseling and Testing Centers employees had high job satisfaction. The highest satisfaction levels were reported in Fars and Kurdistan provinces and the lowest satisfaction levels were reported in Kermanshah and Bushehr. CONCLUSION: According to the findings, in the Iranian treatment centers, the employees' satisfaction were at the same level regardless of their position and workplace. Also, the eastern and western regions of the country reported higher satisfaction score than the southern and central regions.

Analysis of capability, motivation and opportunity to prevent substance abuse in sensation seeking students on the outskirts of a city in Eastern Iran: a qualitative study.

BACKGROUND: Usually, substance abuse begins in adolescence in Iran. Young people who score high on the sensation-seeking trait tend to be more prone to substance abuse and an early experience in using. According to the COM_B model, substance abuse can be observed in situations where a person has the necessary physical and mental abilities, the necessary opportunities, and competing motivations. Therefore the study aimed to deeper understand of capability, motivation, and opportunities of substance abuse behavior to design educational programs. METHODS: This study was conducted based on content analysis approach. Data were collected through a focus group discussion with 18 participants (high school male students) from the outskirts of Birjand, who received a positive score from the Zuckerman Sensation Seeking Questionnaires' summary form. The group discussion was conducted using a guide to semi-structured questions based on COM-B model constructs. RESULTS: Students' knowledge of substance cognition, side effects, and consequences of addiction were incomplete. Some students believed that substance use was a way to control or vent emotions and that smoking was a sedative, and private spaces and uncrowded public places were physical environments that students cited for engaging in substance use. In the analysis, 24 subcategories and 11 categories were identified for the capability analysis section, 16 subcategories and 7 categories for the motivation section, and 21 subcategories and 6 categories for the opportunity section. CONCLUSIONS: In order to achieve more precise prevention interventions against adolescents' tendency for substance abuse and to have a more significant impact on their behaviors, it is beneficial to study the three identified factors in some of the target individuals before intervention.

Anti-lung Cancer Marine Compounds: A Review.

Lung cancer is one of the most common and lethal cancers in human beings. Lung cancer has been divided into two major types: small cell lung cancer (SCLC) and non-small cell lung carcinoma (NSCLC). Current drugs suffer from various side effects, and the insufficient efficacy of present treatments creates a desire for better more efficient new drugs. This review compares the diversity of marine-derived bioactive compounds from different marine species. Some of the natural products from marine resources are in different stages of clinical trials. By the way, most of them have been studied in vitro and in vivo. Additionally, in this review, the mechanisms of action of marine-derived anti-lung cancer components on lung cancer cell lines have been reviewed. In addition, considering growing rate and the high costs of cancer research, attention must be paid to some aspects of targeting and developing anti-lung cancer drug. In better words, like the other therapeutic strategies that have their particular challenges and weak points, several challenges about marine-derived anti-lung cancer components which exist for scientists for doing research are explained. Moreover, as the attentions in the field of cancer therapy are focused on designing and developing new anticancer strategies for the treatment of cancer in the future, the application of marine-derived anti-lung cancer components in the field of future cancer therapy and their role in future anticancer strategies are briefly discussed.

Decellularization of kidney tissue: comparison of sodium lauryl ether sulfate and sodium dodecyl sulfate for allotransplantation in rat.

An automatic decellularization device was developed to perfuse and decellularize male rats' kidneys using both sodium lauryl ether sulfate (SLES) and sodium dodecyl sulfate (SDS) and to compare their efficacy in kidney decellularization and post-transplantation angiogenesis. Kidneys were perfused with either 1% SDS solution for 4 h or 1% SLES solution for 6 h. The decellularized scaffolds were stained with hematoxylin and eosin, periodic acid Schiff, Masson's trichrome, and Alcian blue to determine cell removal and glycogen, collagen, and glycosaminoglycan contents, respectively. Moreover, scanning electron microscopy was performed to evaluate the cell removal and preservation of microarchitecture of both SDS and SLES scaffolds. Additionally, DNA quantification assay was applied for all groups in order to measure residual DNA in the scaffolds and normal kidney. In order to demonstrate biocompatibility of the decellularized scaffolds, human umbilical cord mesenchymal stromal/stem cells (hUC-MSCs) were seeded on the scaffolds. In addition, the allotransplantation was performed in back muscle and angiogenesis was evaluated. Complete cell removal in both SLES and SDS groups was observed in scanning electron microscopy and DNA quantification assays. Moreover, the extracellular matrix (ECM) architecture of rat kidney in the SLES group was significantly preserved better than the SDS group. The hUC-MSCs were successfully migrated from the cell culture plate surface into the SDS and SLES decellularized scaffolds. The formation of blood vessels was observed in the kidney in both SLES and SDS decellularized kidneys. The better preservation of ECM than SDS introduces SLES as the solvent of choice for kidney decellularization.

Birjand longitudinal aging study (BLAS): the objectives, study protocol and design (wave I: baseline data gathering).

OBJECTIVES: The pace of population aging is growing rapidly around the world. Aging is associated with the emergence of different health status including geriatric syndrome such as frailty, diabetes, cardiovascular diseases, and dementia. These conditions are the most prominent challenges for health care systems and also elderly people. Therefore, understanding these changes can help scientists to prevent and treat significant health issues and also improve the functional ability of older adults. METHODS: This is a protocol of the first wave of Birjand Longitudinal Aging Study that is an ongoing community-based prospective cohort study with a following up at least 10 years. This study carries out on aged population ≥ 60 years which were residents in Birjand County (urban and rural older subjects). The selection of the participants of this study in urban areas is based on an age group weighted multistage stratified random sample while in the rural region the sample was selected from all ten rural regions of Birjand County by simple random sampling. The rural region sampling was based on the list of the aged population which were under the coverage of the rural health center. Sociodemographic, past medical history, lifestyle, sleep, activities of daily living, cognitive function, quality of life, and social capital were evaluated by interviewing with the participants and one of the informants. Anthropometric measures, electrocardiography, and interpretation of ophthalmologic examination were carried out by experts. Fasting Blood samples were collected and bio-banked in - 80 °C. then finally biochemical and hematologic markers were measured. RESULTS: This is the protocol of stage one baseline of Birjand Longitudinal Aging Study (BLAS). The BLAS is an enjoining study, the first phase of its baseline was carried out on a community- dwelling aged population sample ≥ 60 years who were residents in urban and rural regions of Birjand County. This is a community based prospective cohort study with at least 10 years follow up of participants. The data for 65% of older subjects (response rate = 65%) that lived in clusters were collected. CONCLUSIONS: This study can help scientists to recognize some risk factors related to the aging process and also aware policymakers about the necessity to create heath care services at regional and even national levels.

Developing and Validating the Functional, Communicative, and Critical Health Literacy Questionnaire among the Iranian General Population.

OBJECTIVES: Many scales have been developed to assess health literacy. These scales have been developed extensively in clinical populations in developed countries. Our study describes the process of development and validation of the Health Literacy Questionnaire to measure health literacy in the general Iranian population. METHODS: We followed the scale development process outlined by Schwab in 1980. After a comprehensive review of the research published on Nutbeam's definition of health literacy and its measurement, two focus groups were considered to generate a pool of items. We then assessed the face validity and content validity of the items. The final version of the questionnaire was subject to independent exploratory and confirmatory factor analysis. The internal consistency of the questionnaire was evaluated using Cronbach's alpha. Finally, construct validity was assessed using bivariate analysis between the total scores on the scale and theoretically relevant variables. RESULTS: The results of exploratory factor analysis revealed a three-factor 14-item structure for the scale. Confirmatory factor analysis provided a good statistical and conceptual fit for the data. The analysis of the internal consistency of the scale was satisfactory (α = 0.798). Further, health literacy was significantly associated with participants' age, educational level, self-rated household income, smoking history, self-rated health, and self-rated health literacy. CONCLUSIONS: The results we obtained indicate that this newly constructed health literacy tool is highly valid and reliable. Prospective studies are required to evaluate the predictive validity of the scale with regard to health outcomes.

A comprehensive study on the application of FeNi3@SiO2@ZnO magnetic nanocomposites as a novel photo-catalyst for degradation of tamoxifen in the presence of simulated sunlight.

Pharmaceutical compounds at trace concentrations are found in the environment, especially in drinking water and food, posing significant negative effects on humans as well as on animals. This paper aimed to examine the diagnostic catalytic properties and efficacy of a novel synthesized photocatalyst, namely FeNi3@SiO2@ZnO magnetic nanocomposite, for the removal of tamoxifen (TMX) from wastewater under simulated sunlight. According to the results, it was found that TMX was completely degraded operating under optimized conditions (i.e. pH = 7, catalyst dose = 0.01 g/L, initial TMX concentration = 20 mg/L and reaction time = 60 min). The reaction kinetics of TMX degradation followed a pseudo-first order kinetics model. The final by-products from the TMX photodegradation were water, carbon dioxide, acetic acid, nitroacetic acid methyl ester, 2-methyl-2-pentenal, and 4-methyl-2-pentanol. In addition, the synthesized photocatalyst could successfully performed five consecutive photodegradation cycles. The obtained results revealed that the synthesized FeNi3@SiO2@ZnO magnetic nanocomposite holds a great potential to be applied as a photocatalyst for the degradation of TMX on an industrial scale.

Segmental Duplications as a Complement Strategy to Short Tandem Repeats in the Prenatal Diagnosis of Down Syndrome.

BACKGROUND: Quantitative fluorescence-polymerase chain reaction (QF-PCR) is an inexpensive and accurate method for the prenatal diagnosis of aneuploidies that applies short tandem repeats (STRs) as a chromosome-specific marker. Despite its apparent advantages, QF-PCR is not applicable in all cases due to the presence of uninformative STRs. This study was carried out to investigate the efficiency of a method based on applying segmental duplications (SDs) in conjunction with STRs as an alternative to stand-alone STR-based QF-PCR for the diagnosis of Down syndrome. METHODS: Fifty amniotic fluid samples from pregnant women carrying Down syndrome fetuses, 9 amniotic fluid samples with 1 or without any informative STR marker (inconclusive), and 100 normal samples were selected from Shiraz, Iran, between October 2015 and December 2016. Analysis was done using an in-house STR-SD-based multiplex QF-PCR and the results were compared. Statistical analysis was performed using MedCalc, version 14. RESULTS: All the normal, Down syndrome, and inconclusive samples were accurately identified by the STR-SD-based multiplex QF-PCR, yielding 100% sensitivity and 100% specificity. Karyotype analysis confirmed all the cases with normal or trisomic results. CONCLUSION: The STR-SD-based multiplex QF-PCR correctly identified all the normal and trisomy 21 samples regardless of the absence of informative STR markers. The STR-SD-based multiplex QF-PCR is a feasible and particularly useful assay in populations with a high prevalence of homozygote STR markers.

Enhancing Stability of Destabilized Green Fluorescent Protein Using Chimeric mRNA Containing Human Beta-Globin 5' and 3' Untranslated Regions.

BACKGROUND: In spite of recent progress in mRNA technologies and their potential applications for treatment of human diseases, problems such as the transient nature of mRNA limit the stability of gene up-regulation and, thus, potentially reduce mRNA efficiency for gene therapy. Using human ß-globin 5' and 3' untranslated regions (UTRs), this study aimed to develop the different chimeric constructs of mRNAs to increase the stability of destabilized green fluorescent protein (EGFPd2) in HEK 293 cells. METHODS: Purified human ß-globin (HBG) 5'-3'UTRs, and the coding sequence of destabilized green fluorescent protein (EGFPd2) were amplified separately and ligated to each other using SOEing PCR method in a different format. As controls, the original construct of EGFPd2 under the control of T7 promoter was used. Following in vitro transcription, HEK 293 cells were then transfected with several constructs and incubated at 37°C in a CO2 incubator. They were monitored under a fluorescence microscope every four hours for the first 24 hr, then every 12 hr afterwards. The resulting fluorescence was measured as a surrogate for translation efficiency and duration. RESULTS: By monitoring the HEK cells over 48 hr, cells transfected with mRNA with various HBG UTRs showed significantly different fluorescence intensity and stability in comparison with the pEGFPd2 prototype (control transcript) overtime. Overall, the images show that replacement of the 3' UTR end of the prototype vector pGFPd2 with the 3' end of ß-globin mRNA increases the half-life of the chimeric mRNA for more than 32 hr. CONCLUSION: This result indicates that ß-globin 3' UTR would definitely increase the half-life of mRNA and may help to decrease the mRNA therapeutic dosage in the treatment of diseases associated with mRNA therapy.

The First Case of a Small Supernumerary Marker Chromosome 18 in a Klinefelter Fetus: A Case Report.

Small supernumerary marker chromosomes (sSMCs), or markers, are abnormal chromosomal fragments that can be hereditary or de novo. Despite the importance of sSMCs diagnosis, de novo sSMCs are rarely detected during the prenatal diagnosis process. Usually, prenatally diagnosed de novo sSMCs cannot be correlated with a particular phenotype without knowing their chromosomal origin and content; therefore, molecular cytogenetic techniques are applied to achieve this goal. The present study aimed to characterize an sSMC in a case of Klinefelter syndrome using an in-house microsatellite analysis method and fluorescent in situ hybridization (FISH) technique. Amniotic fluid was collected from a pregnant woman who was considered to have risk factors for trisomy higher than the screening cut-off. Karyotype analysis was followed by the amplification of different microsatellite loci and FISH technique. Karyotype analysis identified a fetus with an extra X chromosome and also an sSMC with unknown identity. Further investigation of the parents showed that the sSMC is de novo. Microsatellite amplification by quantitative fluorescent PCR (QF-PCR) and FISH analysis showed that the sSMC is a derivative of chromosome 18. Eventually, the patient decided to terminate the pregnancy. Here, the first case of the coincidence of sSMC 18 in a Klinefelter fetus is reported.

Cognitive predictors of cervical cancer screening's stages of change among sample of Iranian women health volunteers: A path analysis.

INTRODUCTION: The uptake of Pap smear among Iranian women is low, resulting in a high rate of casualties from cervical cancer in Iran. The present study used the Health Belief Model (HBM) and the Stages of Change theory as theoretical frameworks for understanding the predictors of the behaviour of Iranian Women Health Volunteers (WHVs) with respect to cervical cancer screening. METHODS: Data from the 1,253 WHVs were analyzed using path analysis to assess the effects of cognitive factors (including knowledge, perceived susceptibility to cervical cancer, perceived severity of cervical cancer, Pap smear benefits, Pap smear barriers, and Pap smear self-efficacy) on the stages of change for Pap-smear behaviour. RESULTS: The majority of the respondents (71.5%) reported that they had not taken previous Pap smear tests; only 3% had received a regular Pap test. The perceived benefits to cervical cancer screening, the perceived barriers to cervical cancer screening, and the perceived self-efficacy to perform cervical cancer screening emerged as the predictors of cervical cancer screening's stages of change; perceived threat to cervical cancer, however, did not. DISCUSSION: Uptake of regular cervical screening for Iranian WHVs was very low. Different interventions, such as media campaigns and educational interventions could provide an opportunity to improve women's knowledge on cervical cancer and Pap test benefits, address any misconceptions or fears about the procedure of the Pap test, and finally increase the cervical screening uptake by Iranian women.

A comparative study of the effectiveness of group-based cognitive behavioral therapy and dialectical behavioral therapy in reducing depressive symptoms in Iranian women substance abusers.

Various therapeutic approaches have been used to improve depressive symptoms in substance abusers. In a quasi-experimental study with a pretest-posttest design and experimental and control groups, we examined and compared the effectiveness of two group-based treatment strategies-cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT)-in reducing depressive symptoms among Iranian women substance abusers. The statistical population included all female addict patients who referred to addiction treatment centers of Birjand city in 2015. A sample of 30 subjects were selected through the available sampling method and randomly assigned into experimental (CBT and DBT) and control groups (each group, 10 patients). The data collection instrument was the Beck Depression Inventory (BDI) questionnaire. The patients in the experimental groups were given skills in eight sessions of 90 min. The data were analyzed by the SPSS-19 software by using mean, standard deviation, and percentages at the descriptive level and analysis of covariance (ANCOVA) test at the inferential level. The comparison of the mean depression score before intervention in all the groups showed no significant difference. However, after intervention, the findings showed that both CBT and DBT interventions could reduce the mean scores of depression in women substance abusers, 17.5 ± 3.0 vs 29.3 ± 4.1 (F[1,17] = 51.91, p value < 0.01) and 14.7 ± 1.8 vs 29.3 ± 4.1 (F[1,17] = 106.62, p value < 0.01), respectively, for CBT and DBT. Post-treatment effect sizes were large and did not differ statistically for CBT (ηp2, 0.75) and DBT (ηp2, 0.86). Therefore, this study highlights the importance of CBT and DBT skills training to substance abusers and provides initial evidence of their effectiveness.

Cultural Adaptation and Psychometric Properties of the Persian Version of the Circumstances, Motivation, and Readiness Scale.

BACKGROUND: Treatment motivation has always been an important issue in substance abuse treatment. In recent decades, several instruments have been developed to measure this concept. OBJECTIVES: In this study, cultural adaptation and psychometric properties of the Persian version of the circumstances, motivation and readiness scale (CMR) are illustrated in a sample of Iranian addicts. MATERIALS AND METHODS: The translation process followed Beaton et al.'s (2000) guideline for the cross-cultural adaptation of self-administered questionnaires, including the steps of translation, synthesis, back translation, expert committee review, and pre-testing. The final version of the Persian CMR was assessed for internal consistency and construct validity (n = 203). RESULTS: There was one eliminated item in the cross-cultural adaptation process. Also, four items that had low correlation with the total score were excluded from the questionnaire during the initial analysis. Using the remaining items, Principle axis factoring with Promax rotation was performed and three factors, circumstance, motivation, and readiness, were identified. The secondary order three factor model provided a good statistical and conceptual fit for the data. Internal consistency met the criterion for a reliable measure (Cronbach's alpha = 0.840). The α range for these identified factors was 0.597 to 0.837. CONCLUSIONS: Although the CMR was originally designed for use in TC treatment, this study suggests that it is also applicable, with some modifications, in short-term residential camps. Also, it is concluded that the Persian translation of the CMR can be applied for studies among Persian addicts.

The effect of instruction on knowledge and attitude of couples attending pre-marriage counseling classes.

BACKGROUNDS: Marriages and establishing a family is one of the most important events in the life of each person. It has significant effects on personal and social health, if it occurs with sufficient knowledge in the proper conditions. The aim of this study is to determine the effect of pre-marriage instruction on the knowledge and health attitudes of the couples attending the pre-marriage counseling classes. MATERIALS AND METHODS: This pre and post quasi-experimental study was conducted on 250 couples attending the pre-marriage counseling classes. The required information was collected using an autonomous questionnaire designed based on the research objectives. The questionnaire included three parts: Demographic information, knowledge (27 questions) and attitude (18 questions. The questionnaire was filled out before and after the pre-marriage counseling program, which was presented as lectures. The effect of the instructional program was analyzed using a statistical test. RESULTS: The results showed that 83.2% of the couples had poor knowledge, 16% average, and 0.8% had good knowledge before the intervention. After the intervention, 60.4% of couples had poor knowledge, 31.6% average and 8% had good knowledge. The results also revealed that that the difference in mean scores of knowledge and attitudes regarding reproductive health, family planning, genetic diseases and disabilities was statistically significant (P < 0.001). CONCLUSIONS: Despite the mean scores of knowledge and attitude of the couples had increased after the instructional intervention, the increase in knowledge level was not very high. So the knowledge score of the couples increased just 4.3%, and only 8% of the couples had good knowledge after the instructional intervention. Therefore, to achieve a relatively stable behavior change in individuals and improving the health level of the young couples, it is recommended that more attention pay to the quality of the instructional classes.

The effect of nutrition and food hygieneeducation on the knowledge of female elementary school teachers in city of ferdows.

INTRODUCTION: Teachers are one of the most influential groups in elevating social health, and their teaching nutritional points to the students can both affect students' awareness and the transferring of such nutritional education to the families. This study was undertaken tosurvey the influence of nutrition and nutritional health education on the awareness of female elementary school teachers. MATERIALS AND METHODS: Fifty-seven female elementary school teachers were chosen from the Ferdows City for this quasi-experimental study. Prior to the outset of the educational workshop, they were asked to fill out a questionnaire about nutrition and nutritional health, which was followed by the two-day workshop. After two months, they were given a second questionnaire. The results were analyzed by paired t-test, ANOVA, and McNemar. In all the tests, a significance level α = 0.05 was considered. RESULTS: Findings of the study showed that the mean score of awareness before interference was 10.98%, which reached up to 18.2% after the interference (P < 0.001). With regard to theimportance of breakfast intake, the teachers' awareness increased from 57.9 to 98.2% from before to after intervention, respectively. CONCLUSION: Applying interventional methods of education in teacher training centers in conjunction with medical and educational centers, with regard to nutrition and nutritional health, can elevate the health of students.

The relationship between emotional intelligence and academic stress in students of medical sciences.

BACKGROUND AND AIM: Emotional intelligence (EI) theory provides a view about predicting effective factors in people's lives whether in education or profession. According to earlier studies, people who have higher emotional skills are more successful in many of life aspects :e.g., reaction to stress and controlling stress situations. Since students are the future of society, this study was carried out to evaluate the relationship between EI and education stress in the students of Birjand University of Medical Sciences (BUMS). MATERIALS AND METHODS: In this cross-sectional study, 260 students were selected by proportional sampling in four faculties: Medicine, Nursing and Midwifery, Paramedical Sciences, and Health. Data were collected using two questionnaires: The standardized EI Shering's (33 questions, five domains) and the Student-Life Stress Inventory (57 questions, nine domains). The obtained data were analyzed by independent t-test, Pearson's correlation coefficient, and linear regression at the significant level of α = 0.05. RESULTS: Totally, 65.8% of participants were females and 31.1% were males. The educational level of the participants included Associate's degree (44.6%) Bachelor's degree in science (31.2%), and medical science (23.1%). There was no significant correlation between EI scores and educational stress in students. But there was a significant relationship between EI with sex (P = 0.02) and mean of EI scores with three domains of academic stress: Personal favorites (P = 0.004), reaction to stressors (P = 0.002), and performance in stressful situations (P = 0.001). CONCLUSION: Although EI growth in different individuals can promote their success, it cannot decrease academic stress by itself which was particularly significant in females. Therefore, other causes of stress such as individual differences must be taken into consideration.
