Satureja khuzestanica is an endemic plant of Iran that is widely distributed in the Southern part of the country. It has antioxidant properties and thus it seems to be useful in diseases related to oxidative stress such as diabetes and hyperlipidemia. The present study investigates the effect of S. khuzestanica supplement in metabolic parameters of hyperlipidemic patients with type 2 diabetes mellitus. Twenty-one hyperlipidemic patients with type 2 diabetes mellitus were randomized in a double blind, placebo controlled clinical trial to receive either S. khuzestanica (tablets contain 250 mg dried leaves) or placebo once a day for 60 days. Blood samples were obtained at baseline and at the end of the study. Samples were analyzed for levels of glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, creatinine, thiobarbituric acid reactive substances (TBARS) as marker of lipid peroxidation and ferric reducing ability (total antioxidant power, TAP). Treatment of patients by S. khuzestanica for 60 days induced significant decrease in total cholesterol (P 0.008) and LDL-cholesterol (P 0.03) while increased HDL-cholesterol (P 0.02) and TAP (P 0.007) in comparison with the baseline values. S. khuzestanica did not alter blood glucose, triglyceride, creatinin and TBARS levels. In comparison with baseline values, no significant change was observed in blood glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, creatinine, TBARS and TAP in placebo-treated group. Usage of S. khuzestanica as a supplement to drug regimen of diabetic type 2 patients with hyperlipidemia is recommended. © 2008 The Author(s).

Objectives: This study was conducted to estimate the prevalence and the associated factors of high-risk sexual behaviors among drug abusers referred to a methadone clinic in Gorgan, the capital of Golestan province in the northeast of Iran, to help health care decision makers on designing interventional programs. Methods: In this cross-sectional study, 400 drug abusers referred to our methadone clinic were evaluated for high-risk sexual behavior. A logistic regression model was fitted for the association between independent variables and high-risk sexual behavior. Results: Approximately a quarter of patients (25.5%) had high-risk sexual behavior among which 47% had not used a condom in their last sexual contact. Drug abusers who had poor economic status had a lower chance of high-risk sexual behavior than those with good economic status (adjusted odds ratio [AOR] = 0.35, 95% confidence interval [CI] = 0.13-0.96). Also, 1-year increase in age reduced the chance by 6% (AOR = 0.94, 95% CI = 0.91-0.98). Heroin abusers, compared with opium abusers, had a duplicated chance of having high-risk sex (AOR = 2.11, 95% CI = 1.12-3.96). Conclusion: According to this study, high-risk sexual behavior in the drug abusers referred to methadone clinic was associated with younger age, good economic status, and heroin addiction. Hence, in interventional planning, more attention should be paid to young drug abusers, patients with good economic status, and heroin addicts as well.

Thyroid | Year: 2011

Background: Germ-line mutations of RET proto-oncogene are the known cause of hereditary medullary thyroid carcinoma (MTC), which account for approximately 25% of all MTC cases and occur as multiple endocrine neoplasia type 2 syndromes. Here, we present the first comprehensive genetic screening and analysis of MTC among Iranian families. Methods: A total of 55 patients with MTC (male to female ratio=1:1.6; average age of disease onset=33±13 years) from 53 independent families participated in this study. All of the patients had undergone total thyroidectomy between 1999 and 2006, and 51 of them were clinically characterized as apparently sporadic cases. Genomic DNA samples were obtained and following highly-specific polymerase chain reaction amplification of the 6 RET key exons (10, 11, 13, 14, 15, and 16) were subjected to direct DNA sequencing without a requirement for a purification step. Results: Sequence analysis revealed that 9 (17.6%) of the apparently sporadic cases (from 8 kindreds) carried an RET germ-line mutation. Of the seven different mutations identified among all of the families studied, five were in the cysteine codons, with Cys634Arg having the highest prevalence (45.5%) among the afflicted families. Mutation carriers have an earlier age of onset (21±6) versus the sporadic cases (37±12). Conclusions: This is the first comprehensive genetic screening and analysis of MTC among Iranian families. The results further confirm the need and advantages of DNA sequencing for identification of hereditary MTC cases. There does not seem to be a meaningful correlation between single nucleotide polymorphism patterns and the average age of disease onset. Geographical distribution of the sporadic cases, however, shows a significant concentration toward the Northern regions of the country, noticeably the provinces situated directly to the south of the Caspian Sea. © Copyright 2011, Mary Ann Liebert, Inc.

Background: It has been suggested that food fortification might be an inexpensive, simple and effective way to control and prevent iron deficiency and its related anemia in many countries. Despite the advantages of this approach and the fact that it has been implemented in some provinces in Iran for more than 6 years, many scientists in the country worry about the negative aspects of the extra iron distributed among non-anemic persons in the community. Objective: This study was designed to assess the effect of the flour fortification program on oxidative stress biomarkers and iron status among non-anemic 40- to 65-year-old adults. Study Design: This study had a special design that was implemented in 3 different parts. The main and first part was a field study. We randomized 2 cities in 1 province. In each city, 200 volunteers (100 men and 100 women) were selected using a multi-stage stratified method. Examination and interview (filling out data collection forms) were the methods of data gathering. In each of the 3 phases, demographic, anthropometric, blood pressure, micro- and macronutrient intakes, physical activities, and some oxidative stress biomarkers were the main data that were gathered. The results of this study can help health policy makers in designing future interventions in the country based on food fortification. © 2010 S. Karger AG, Basel.

Background: Family planning has been defined in the framework of mothers and children plan as one of Primary Healthcare (PHC) details. Besides quantity, the quality of services, particularly in terms of ethics, such as observing individuals' privacy, is of great importance in offering family planning services. Objective: A preliminary study to gather information about the degree of medical ethics offered during family planning services at Tehran urban healthcare centers. Materials and Methods: A questionnaire was designed for study. In the first question regarding informed consent, 47 clients who were advised about various contraception methods were asked whether advantages and disadvantages of the contraceptive methods have been discussed by the service provider. Then a certain rank was measured for either client or method in 2007. Finally, average value of advantage and disadvantage for each method was measured. In questions about autonomy, justice and beneficence, yes/no answers have been expected and measured accordingly. Results: Health care providers have stressed more on the advantages of pills and disadvantages of tubectomy and have paid less attention to advantages of injection ampoules and disadvantages of pills in first time clients. While they have stressed more on the advantages and disadvantages of tubectomy and less attention to advantages of condom and disadvantages of vasectomy in second time clients. Clients divulged their 100% satisfaction in terms of observing turns and free charges services. Observance degree of autonomy was 64.7% and 77.3% for first time and second- time clients respectively. Conclusion: Applying the consultant's personal viewpoint for selecting a method will breach an informed consent for first and second time clients. System has good consideration to justice and no malfeasance.

Background: Cognitive impairment is a prevalent health problem in older people and its global prevalence tends to increase parallel to the extended life expectancy in world. The beneficial effect of ω-3 PUFAs on cognitive impairment has been demonstrated in some experimental and cohort studies. In this study we aimed to assess the effect of low dose docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) supplementation on cognitive status in the elderly.Methods: In a double-blind, randomized placebo-controlled study, 199 individuals aged ≥65 years with normal or mild to moderate cognition impairment were assigned to receive either 180 mg of DHA plus 120 mg of EPA or placebo for 180 days. Cognitive status was assessed using Mini-Mental State Examination (MMSE) and Abbreviated Mental Test (AMT) score.Results: MMSE and AMT scores were not different at the time of allocation [18.84 (5.37), 18.55 (5.12), (P = 0.70) and 4.81 (2.79) and 4.64 (2.77), (P = 0.67) respectively] and over 6 months between the ω-3 PUFA- and placebo- treated groups [18.57 (5.21), 18.39 (5.10), (P = 0.80) and 4.64 (2.77) and 4.48 (2.69) and (P = 0.67)]. The participants were categorized based on MMSE score into normal cognition, mild and moderate cognitive impairment. After multivariate adjustment, there was no significant difference among categorized groups regarding the ω-3 PUFA effect except in normal cognition group, that amount of decline in AMT in ω-3 poly unsaturated fatty acids (PUFAs) was less than placebo group.Conclusions: It seems that prescription of low dose ω-3 PUFAs for 6 months had no significant beneficial effects on improvement of cognition or prevention of cognitive decline in older people. © 2014 Mahmoudi et al.; licensee BioMed Central Ltd.

Survivin is an inhibitor of apoptosis protein, which is up-regulated in endometrial cancer (EC). A promoter region polymorphism (-31G/C) in the survivin gene has been reported as a modulator of gene expression. The aim of this study was to explore the frequency of survivin -31G/C polymorphism in tumor tissues from patients with EC in an Iranian population compared to that of healthy controls.Paraffin-embedded tissue sections from patients diagnosed with EC (n = 31) and healthy controls (n = 30) were examined. Genotyping for survivin -31G/C polymorphism was performed using polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP).The presence of allele C was found to be significantly increased in EC tissues compared to the healthy tissues (GG vs GC + CC, P = 0. 01; OR, 3.6; 95% CI, 1.1-11.9).Our data are in keeping with a previous finding regarding the role of survivin gene polymorphism in malignancies. This finding highlights the role of survivin in pathogenesis of various carcinomas, which might have therapeutic implications.
