Maryam Vahidi,Nader Mahdavi,Elnaz Asghari,Hossein Ebrahimi,Jamal Eivazi Ziaei,Mina Hosseinzadeh,Hossein Namdar Areshtanab,Iraj Asvadi Kermani 한국간호과학회 2016 Asian Nursing Research Vol.10 No.3
Purpose: This study aimed to determine factors associated with caregiver burden among primary caregivers of women with breast cancer in Iran. Methods: This was a descriptive correlation study conducted in 2012 on 150 main caregivers of patients with breast cancer who came to the oncology clinic of Shahid Ghazi hospital in Tabriz, Iran. A questionnaire which included caregiving-related factors and the Zarit Burden Interview was used for data collection after its validity and reliability were determined. Data was analyzed using SPSS 13.0 software with descriptive and analytic statistics. The association between significant variables and the dependent variable with an observation of the effects of other variables was assessed using the multiple linear regression model. Results: The mean age of caregivers was 39.60 ± 13.80 years old, and 77 (51.3%) of them were men. The mean score of the Zarit Burden Interview was 30.55 ± 19.18. In the regression model, the mean score of activities of daily living, level of education, gender, and financial status were identified as the determining factors of the burden of caregivers. Conclusions: Primary caregivers need to be financially supported by the relevant organizations. Care skills training and providing palliative care seem helpful in reducing the pain and the burden of family caregivers for patients with breast cancer.

In recent years, the use of supplementary cementing materials, especially in addition to concrete, has been the subject of many researches. Rice husk ash (RHA) is one of these materials that in this research, is added to the roller compacted concrete as one of the pozzolanic materials. This paper evaluates how different contents of RHA added to the roller compacted concrete pavement specimens, can influence on the strength and permeability. The results are compared to the control samples and determined optimal level of RHA replacement. As it was expected, RHA as supplementary cementitious materials, improved mechanical properties of roller compacted concrete pavement (RCCP). Also, the application of adaptive neuro-fuzzy inference system (ANFIS) in predicting the permeability and compressive strength is investigated. The obtained results shows that the predicted value by this model is in good agreement with the experimental, which shows the proposed ANFIS model is a useful, reliable, fast and cheap tool to predict the permeability and compressive strength. A mean relative error percentage (MRE %) less than 1.1% is obtained for the proposed ANFIS model. Also, the test results and performed modeling show that the optimal value for obtaining the maximum compressive strength and minimum permeability is offered by substituting 9% and 18% of the cement by RHA, respectively.

Risk Factors for Breast Cancer in Iranian Women: A Hospital-Based Case-Control Study in Tabriz, Iran
Mina Hosseinzadeh,Jamal Eivazi Ziaei,Nader Mahdavi,Parvaneh Aghajari,Maryam Vahidi,Alaviehe Fateh,Elnaz Asghari 한국유방암학회 2014 Journal of breast cancer Vol.17 No.3
Purpose: Breast cancer is the most common cancer in womenworldwide and the leading cause of cancer death among women. In Asian countries such as Iran, the incidence of breast canceris increasing. The present study aimed to assess the riskfactors for breast cancer of women in Tabriz, Iran. Methods: Ahospital-based case-control study was undertaken to identifybreast cancer risk factors. The study consisted of 140 casesconfirmed via histopathological analysis and 280 group-matchedcontrols without any malignancy. Data were analyzed using descriptiveand inferential statistical methods via the SPSS softwareversion 18. Results: In a multivariate analysis, educationallevel (odds ratio [OR], 4.7; 95% confidence interval [CI], 2.11–10.83), menopausal status (OR, 2.54; 95% CI, 1.41–4.59), ahigh-fat diet (OR, 2.76; 95% CI, 1.51–5.04), abortion (OR, 2.13;95% CI, 1.20–3.79), passive smoking (OR, 2.76; 95% CI, 1.51–5.04), oral contraceptive use (OR, 3.18; 95% CI, 1.80–5.59),stress (OR, 3.05; 95% CI, 1.74–5.36), and migration (OR, 3.09;95% CI, 1.39–6.90) were factors associated with a significantlyincreased risk of breast cancer. Breastfeeding (OR, 0.39; 95%CI, 0.16–0.97) and a diet containing sufficient fruit and vegetables(OR, 0.22; 95% CI, 0.12–0.39) had protective roles againstbreast cancer. Conclusion: The study revealed that the risk factorsfor breast cancer among women in the Tabriz area of Iranare related to the lifestyle. Therefore, the provision of educationto change unhealthy lifestyle choices and periodic check-ups forearly breast cancer detection are recommended.
