Comparison of Training via Short Messages and Group Training on Level of Knowledge and Practice of Middle-Aged Women About Breast Cancer Screening Tests

This study is aimed to compare the effect of two methods of short messages and group training on level of knowledge and practice of middle-aged women about breast cancer screening procedures. This clinical trial study was done on 210 women aged 40–60 years in Mahshahr city, Iran. Eligible middle-aged women were randomly assigned in two groups of short message (n = 105) and group training (n = 105). Data collected through a questionnaire which included three parts (demographic, knowledge and practice of women about breast cancer and screening procedures). Group training was educated for two sessions in 2 weeks that each session lasted 2 h. In the short message group, every woman received texts about breast cancer, reasons, and preventive methods, three times a week, for 2 weeks. The questionnaire (knowledge and practice) was completed 2 months after educational intervention. Data was analyzed using independent t test, paired t test, and chi-square. Results of this study showed that average score of knowledge in two groups increased significantly, from 34.4 ± 7.54 to 40. 8 ± 7.18 in the short text messages (SMS) and from 35 to 39.75 in the group training (P > 0.05). Also, the score of breast examination by health provider in the SMS group was significantly higher than that in the group training, but the score of breast self-examination in the group training was higher than that in the short message (P < 0.05). The results showed that training by each way is effective to increase knowledge and performance of women about breast cancer screening methods. Further studies to compare the cost-effectiveness of two methods are recommended.     

Application of Geant4 Monte Carlo simulation in dose calculations for small radiosurgical fields

The Geant4 toolkit was used to develop a Monte Carlo (MC)-based engine for accurate dose calculations in small radiation field sizes. The Geant4 toolkit (version 10.1.p02) was used to simulate 6-MV photon beam of a Varian2100C linear accelerator that is being used for stereotactic radiosurgery (SRS) treatment with small radiation fields. Geometric models of 3 in-house designed radiosurgical divergent cones, with the diameters of their projections at the isocenter being 10, 20, and 30?mm, were simulated. The accuracy of the MC simulation technique was examined by reproducing several different simulated dosimetric parameters of the primary beams with the experimental data. The dose distributions are first checked for single beams for each cone, then standard multiple field (SMF) techniques are applied. A sample set of DICOM files from computed tomography (CT) scan imaging of a patient's head was converted to the Geant4 geometry format to implement MC-based engine for a clinical test. To validate the accuracy of the MC-based calculations for SMF arrangements, the isodose lines from MC simulation in water phantom were compared with the measured isodose lines using EBT3 Gafchromic film in Solid Water phantoms. Agreements between measured and simulated depth dose values and beam profiles for SRS cones were generally within 2%/2?mm. For output factors, the largest discrepancy was observed for 10?mm SRS cone, which was 1.7%. For SMF techniques, in SRS cones, the MC simulation and EBT3 Gafchromic film dosimetry were in acceptable agreement (5%/5?mm). Excellent agreement between the results of the MC-based and measured dose values for both single and SMF techniques in SRS cones indicates the ability of the Geant4 toolkit to be applied as the platform for treatment planning of advanced radiotherapy techniques.     

Effects of garlic extract on TNF-α expression and oxidative stress status in the kidneys of rats with STZ + nicotinamide-induced diabetes

Context: Allium sativum L. (Liliaceae) (garlic) is a medicinal plant that is widely used in herbal medicine. Nephropathy is a complication of diabetes that is induced by long-term hyperglycaemia.

Objective: The effects of aqueous extract of garlic (AGE) on the expression of tumour necrosis factor-alpha (TNF-α) and oxidative stress status were studied in the kidneys of rats with streptozotocin (STZ)?+?nicotinamide-induced diabetes.

Materials and methods: Twenty-four Wistar rats were divided into four groups: control rats, rats with STZ?+?nicotinamide-induced diabetes that received a single dose of STZ (65?mg/kg) and nicotinamide (110?mg/kg) intraperitoneally, diabetic rats that were treated with garlic (2?g/kg/d, gavage), and normal rats that received garlic (2?g/kg/d, gavage). The glucose level was determined in the start of study, 7 d after induction of diabetes and 33 d after treatment with garlic. At the end of the treatment period, urea, uric acid and creatinine levels were estimated in sera. Malondialdehyde (MDA), total oxidant status (TOS), nitric oxide (NO) levels and TNF-α gene and protein expression were measured in the renal tissues of the rats.

Results: The glucose, uric acid, and urea levels increased in the serum of diabetic rats compared with control rats, and decreased in garlic-treated diabetic rats compared with diabetic rats (p?p?p?p?p?Discussion and conclusion: These results indicate that garlic extract has hypoglycaemic, antioxidant and anti-inflammatory properties; therefore, it can be useful for the alleviation of diabetic complications.

Screening of the pelvic organ prolapse without a physical examination; (a community based study)

Background

The attendance rate in Estonian cervical cancer screening programme is too low therefore the programme is hardly effective. A cross-sectional population based survey was performed to identify awareness of cervical cancer risk factors, reasons why women do not want to participate in cervical screening programme and wishes for better organisation of the programme.

Method

An anonymous questionnaire with a covering letter and a prepaid envelope was sent together with the screening invitation to 2942 randomly selected women. Results are based on the analysis of 1054 (36%) returned questionnaires.

Results

Main reasons for non-participation in the national screening programme were a recent visit to a gynaecologist (42.3%), fear to give a Pap-smear (14.3%), long appointment queues (12.9%) and unsuitable reception hours (11.8%). Fear to give a Pap-smear was higher among women aged 30 and 35 than 50 and 55 (RR 1.46; 95% CI: 0.82-2.59) and women with one or no deliveries (RR 1.56, 95% CI: 0.94-2.58). In general, awareness of cervical cancer risk factors is poor and it does not depend on socio-demographic factors. Awareness of screening was higher among Estonians than Russians (RR 1.64, 95% CI: 1.46-1.86). Most women prefer to receive information about screening from personally mailed invitation letters (74.8%).

Conclusions

Women need more information about cervical cancer risk factors and the screening programme. They prefer personally addressed information sharing. Minority groups should be addressed in their own language. A better collaboration with service providers and discouraging smears outside the programme are also required.
