The aim of this study was to investigate the effectiveness of EASY Minds on mathematics anxiety and mathematics self-efficacy in students with dyscalculia. This study was quasi-experimental using a pre-test, post-test, with a control group design. The statistical population consisted of 157 students with dyscalculia who referred to the Center of Learning Disabilities of Department of Education in Dezful in 2018-2019 school year. Using convenience sampling and considering the requirements of the research project based on Malekpour Dyscalculia Diagnosis Questionnaire, Wechsler Intelligence Scale of Children, the fifth Diagnostic and Statistical Manual of Mental Disorder (DSM-5), 40 students were selected and assigned to an experimental group (n=20) and a control group (n=20). The measurement tools were mathematics self-efficacy Questionnaire and mathematics anxiety Scale. The experimental group received 14 sessions (60 minutes each) of group training. For data analysis, mixed variance analysis with repeated measures design is used. Findings showed that EASY Minds training has a significant effect on mathematics anxiety and mathematics self-efficacy and this effect remains unchanged in the two-month follow-up phase (P<0.05). Finally, we can conclude that EASY Minds training, as an effective and functional intervention, could be used to improve mathematics anxiety and mathematics self-efficacy of students with dyscalculia.

Although lung transplantation is a well-accepted treatment for end-stage lung diseases patients, only 15%–20% of the brain-dead donors’ lungs are usable for transplantation. This results in high mortality of candidates on waiting lists. Ex-vivo lung perfusion (EVLP) is a novel method for better evaluation of a potential lung for transplantation.
To report the first experience of EVLP in Iran.
The study included a pig in Vienna Medical University, Vienna, Austria, and 4 humans in Masih Daneshvari Hospital, Tehran, Iran. All brain-dead donors from 2013 to 2015 in Tehran were evaluated for EVLP. Donors without signs of severe chest trauma or pneumonia, with poor oxygenation were included.
An increasing trend in difference between the pulmonary arterial pO2 and left atrial pO2, an increasing pattern in dynamic lung compliance, and a decreasing trend in the pulmonary vascular resistance, were observed.
The initial experience of EVLP in Iran was successful in terms of important/critical parameters. The results emphasize on some important considerations such as precisely following standard lung harvesting and monitoring temperature and pressure. EVLP technique may not be a cost-effective option for low-income countries at first glance. However, because this is the only therapeutic treatment for endstage lung disease, it is advisable to continue working on this method to find alternatives with lesser costs.

Her2/neu is a biomarker which is overexpressed in a subset of breast cancer patients who are eligible to receive treatment. Her-2 gene amplification analyzed by MLPA that is a new method to detect Her-2 status in clinical practice. 60 patients, who were operated in Afzalipour Hospital of Kerman, were enrolled in this cross-sectional study. The pathologic specimens were evaluated by MLPA method for detecting HER2 overexpression. The data were analyzed by SPSS21 software and CHI SQUARE test. Correlation between HER2 overexpression and lymph node involvement was remarkable (P value=0.0). HER2 over overexpression and size of tumor had obvious relation (P value=0.036). All the patients with HER2 overexpression were stage3 of malignancy (P value=0.0). According to the results of this study it can be concluded MLPA method is a suitable method for detecting overexpression of HER2 in patients with breast cancer.

Some studies have shown the relationship between occupational stress and organizational productivity، physical and psychological complications in employee including nursing staffs. However، its relationship with family matters and marital satisfaction of nurses has been less investigated. This study aimed to evaluate the association between occupational stress and marital satisfaction in nurses. This cross-sectional study was conducted with 200 nurses working in selected hospitals of Shahid Beheshti University of Medical Sciences، Tehran. The participants were selected using a clustered random sampling method. The instrument had three sections: demographic data، occupational stress and marital satisfaction questionnaires. In order to data analysis the descriptive statistics، Pearson correlation coefficient، multivariate regression analysis، t-test and ANOVA performed using SPSS v. 16. 0. The mean scores of occupational stress and marital satisfaction were 104. 11 ± 16. 42 and 169. 65 ± 28. 38، respectively. Significant correlation was observed between occupational stress and marital satisfaction (r=-0. 517، p<0. 001). Based on the regression model، the role compatibility could to define 0. 758 of the marital satisfaction، while role ambiguity، relationships with superiors and ergonomic factors defined -0. 123، -0. 136 and -0. 095 of the marital satisfaction، respectively. Occupational stress was significantly associated with marital satisfaction of nurses. Nurses’ knowledge of stress management in work settings may help them to cope better with the work environment and it also has an influence on marital satisfaction.
