Investigating the effect of nurses’ supportive and educative careon the quality of life in breast cancer patients referred for radiotherapy in Seyedoshohada hospitals in Isfahan in 1392
Background and aims: breast cancer is the most common cancer among women in Iran and many countries; but in recent years, survival rate was longer in patients and yet there is a greater emphasis on their quality of life. Therefore, this study was aimed to evaluate the effect of nurses’ supportive and educative care on the quality of life in breast cancer patients.
Methods: This is a quasi-experimental, pre- and post- study. 45 patients with breast cancer referred to radiotherapy clinic of Seyedoshohada hospital were studied in 2013. The instruments used in this study were demographic and quality of life questionnaires from Backman institute completed before and after the training and support for patients. Questionnaires were completed and finally the obtained data were analyzed using SPSS software and statistical tests.
Results: Based on the results obtained on the overall quality of life, it was observed that the average score for the quality of life in the sample was 51.73±13.91 before the intervention and 60.46±13.80 after the intervention (P<0.001). Also, the average scores in all four domains of quality of life after the intervention has increased, but the difference was significant only in two dimensions, physical and mental health (P<0.001).
Conclusion: The results confirm the positive effect of nurses’ supportive and educative programs on the promotion of quality of life in patients with breast cancer. Therefore, planning and implementation of such programs on a broader basis and based on the educational and supportive patients' needs is recommended
Treatment of a Maxillary First Molar with Two Palatal Roots
Thorough knowledge of the morphology and internal anatomy of the root canal system is essential, because it determines the successful outcome of endodontic treatment. The main goal of endodontic treatment is to prevent apical periodontitis and/or to promote the healing of periapical lesion. Presence of two canals or roots on the palatal side of the first maxillary molar has rarely been reported. This case report presents a maxillary first molar with two separate palatal roots.Keywords: Anatomic Variation; Maxillary First Molar; Palatal Root; Root Canal Anatomy
Marked increase in breast cancer incidence in young women : A 10-year study from Northern Iran, 2004-2013
Introduction: Breast cancer is the most frequent cancer among women worldwide. Breast cancer incidence in young women is a health issue of concern, especially in middle-income countries such as Iran. The aim of this study is to report the breast cancer incidence variations in Golestan province, Iran, over a 10-year period (2004-2013). Methods: We analyzed data from the Golestan Population-based Cancer Registry (GPCR), which is a high-quality cancer registry collecting data on primary cancers based on standard protocols throughout the Golestan province. Age-standardized incidence rates (ASRs) and age-specific incidence rates per 100,000 person-years were calculated. Time trends in ASRs and age-specific rates were evaluated using Joinpoint regressions. The average annual percentage change (AAPC) with correspondence 95% confidence intervals (95%CIs) were calculated. Results: A total of 2106 new breast cancer cases were diagnosed during the study period. Most cases occurred in women living in urban areas: 1449 cases (68%) versus 657 cases (31%) in rural areas. Statistically significant increasing trends were observed over the 10-year study period amongst women of all ages (AAPC = 4.4; 95%CI: 1.2-7.8) as well as amongst women in the age groups 20-29 years (AAPC = 10.0; 95%CI: 1.7-19.0) and 30-39 years (AAPC = 5.1; 95%CI: 1.4-9.0). Conclusion: The incidence of breast cancer increased between 2004 and 2013 in Golestan province amongst all age groups, and in particular amongst women aged 20-39 years. Breast cancer should be considered a high priority for health policy making in our community.Peer reviewe
Determination of Dosimetric Parameters of the Second Model of Pd-103 Seed Manufactured at Agricultural, Medical and Industrial Research School
Introduction: The use of low energy isotopes such as 103 Pd in brachytherapy for the treatment of cancers such as prostate, eye, head, neck, breast and cervix is increasing. In this regard, different models of Pd- 103 seeds have been designed and manufactured at the Agricultural, Medical and Industrial Research School (AMIRS) of Atomic Energy Organization of Iran. In this research, the dosimetric parameters of the second model of Pd-103 seed manufactured at AMIRS have been calculated and measured. Materials and Methods: The dosimetric parameters of the second Pd-103 seed manufactured at AMIRS were determined according to TG-43U1 protocol using Monte Carlo calculations (MCNP4C computer code) and measurements performed using TLD-GR200A dosimeters in a Perspex phantom. The parameters include dose rate constant, geometry function, radial dose function, anisotropy function, anisotropy factor and anisotropy constant. Results: It was found that by using MCNP4C code the calculated dose rate constant in water and Perspex was 0.706±0.001 and 0.501±0.001 cGyh -1 U -1 , respectively. Using the calculated geometry function, the radial dose function and the anisotropy function were determined by experimental and theoretical methods in water and Perspex phantom. Also, the calculated value of anisotropy constant in water was equal to 0.88. Discussion and Conclusion: A discrepancy of less than 10% between the calculated and the measured values indicates a reasonable agreement between the simulation and the measurement method. Also, the dosimetric parameters of this seed have been compared to the dosimetric parameters of the first Pd-103 seed manufactured at AMIRS and some other seeds. The obtained results indicate that the seeds manufactured at AMIRS have acceptable dosimetric parameters suitable for brachytherapy applications
