Impacts of tomato extract on the mice fibrosarcoma cells

Introduction: The anticancer effect of tomato lycopene has been approved in some cancers. This study was aimed to determine the prohibitive and therapeutic effects of tomato extract on the growth of fibrosarcoma in mice. Materials and Methods: In this experimental study 3 groups of 10 male Balb/c mice were injected subcutaneously with 5&times;105 WEHI-164 tumor cells in the chest area. Prevention group was fed tomato extract (5 mg) for a 4 week period (from 2 weeks before tumor cell injection up to 2 weeks after injection) and the treatment group was fed simultaneously with tumor cell injection up to two weeks after injection daily by an oral gastric tube. The tumors areas were measured and recorded on days 10, 12, 14, 16, 18, 20 and 22. The data were analyzed using Kruskal-Wallis and Mann-Whitney tests. Results: The results showed that the tumor areas in control group were significantly more after the intervention than two groups of treatment and prevention (p&lt;0.05). The difference was not statistically significant between the two groups of prevention and treatment. Conclusion: With emphasize on antioxidant of tomato, it seems that tomato extract has an important role in prevention and control fibrosarcoma growth.</p

Situation of fruits and vegetables consumption in the dormitory female students based on the theory of planned behavior

Background and objective: Non correct nutrition is one of the most important risk factors for cardiovascular disease, hypertension, diabetes, and obesity. The aim of this study was to determine the status of fruits and vegetables consumption in dormitory female students of Tehran University of Medical Sciences based on the theory of planned behavior. Methods: This cross-sectional study was down on 300 female students dormitories of Tehran University of Medical Sciences. Samples were selected by random sampling. Data gathered by a questionnaire with 13 demographic questions, 42 questions about daily consumption of fruits and vegetables, 2 questions of behavioral intention, 15 questions of attitude, 5 questions of subjective norms, 7 questions about perceived behavioral control and 5 questions of enabling factors. Validity and reliability of the questionnaire was determined in a pilot study. Data were analyzed by SPSS software (version16) and using descriptive and analytical statistics tests. Results: 86% of the samples had favorable behavioral intentions, all of them had desirable attitudes. 63 percent of them had favorable subjective norms and 78 percent of them had favorable perceived behavioral control and 84.7 percent of them had favorable enabling factors. There were significant correlations between fruit and vegetable consumption behaviors with the intention, perceived behavioral control and enabling factors based on the correlation co-efficient and leaner regression Tests. Intention, perceived behavioral control and enabling factors were predictors of fruits and vegetables consumption among these students. Conclusion: Intention, perceived behavioral control and enabling factors were important predictors of fruit and vegetable consumption in these students. Paper type: Research Articl

Prevalence of and reasons for women’s, family members’, and health professionals’ preferences for cesarean section in Iran: a mixed-methods systematic review

Abstract: Background: Cesarean section (CS) rates have been increasing globally. Iran has one of the highest CS rates in the world (47.9%). This review was conducted to assess the prevalence of and reasons for women’s, family members’, and health professionals’ preferences for CS in Iran. Methods and findings: In this mixed-methods systematic review, we searched MEDLINE/PubMed, Embase, CINAHL, POPLINE, PsycINFO, Global Health Library, Google scholar; as well as Iranian scientific databases including SID, and Magiran from 1 January 1990 to 8th October 2019. Primary quantitative, qualitative, and mixed-methods studies that had been conducted in Iran with Persian or English languages were included. Meta-analysis of quantitative studies was conducted by extracting data from 65 cross-sectional, longitudinal, and baseline measurements of interventional studies. For meta-synthesis, we used 26 qualitative studies with designs such as ethnography, phenomenology, case studies, and grounded theory. The Review Manager Version 5.3 and the Comprehensive Meta-Analysis (CMA) software were used for meta-analysis and meta-regression analysis. Results showed that 5.46% of nulliparous women (95% CI 5.38–5.50%; χ2 = 1117.39; df = 28 [p < 0.00001]; I2 = 97%) preferred a CS mode of delivery. Results of subgroup analysis based on the time of pregnancy showed that proportions of preference for CS reported by women were 5.94% (95% CI 5.86–5.99%) in early and middle pregnancy, and 3.81% (95% CI 3.74–3.83%), in late pregnancy. The heterogeneity was high in this review. Most women were pregnant, regardless of their parity; the risk level of participants were unknown, and some Persian publications were appraised as low in quality. A combined inductive and deductive approach was used to synthesis the qualitative data, and CERQual was used to assess confidence in the findings. Meta-synthesis generated 10 emerging themes and three final themes: ‘Women’s factors’, ‘Health professional factors’, andex ‘Health organization, facility, or system factors’. Conclusion: Despite low preference for CS among women, CS rates are still so high. This implies the role of factors beyond the individual will. We identified a multiple individual, health facility, and health system factors which affected the preference for CS in Iran. Numerous attempts were made in recent years to design, test and implement interventions to decrease unnecessary CS in Iran, such as mother-friendly hospitals, standard protocols for labor and birth, preparation classes for women, midwives, and gynaecologists, and workshops for specialists and midwives through the “health sector evolution policy”. Although these programs were effective, high rates of CS persist and more efforts are needed to optimize the use of CS
