Esophageal cancer in Iranian Turkmens: An ethnic disparity concern

The association between ethnic diversity in Turkmen population with esophageal cancer incidence in Iranian Turkmens (Golestan province) was trying to explore in the present study. This is a cross sectional study in Turkmen patients with confirmed diagnosis of esophageal cancer between 2002 through 2003 at a referral clinic in Gonbad. One hundred and six Turkmen patients, diagnosed with esophageal cancer by endoscopy and biopsy, were included. Demographic factors (sex and age), cancer histology (SCC and adenocarcinoma), tumor origin (upper 3rd, middle 3rd and lower 3rd of esophagus) and patients' contact numbers were retrieved and the patients were categorized into five different groups based on their ethnicity: Ahtahbai, Jafarbai, Googlan, others and unidentified ethnic group. Incidence rate was estimated based on the number of patients and population of each ethnic group. Descriptive statistics was performed and data were analyzed by Kruskal-Wallis Test for continuous variables and Chi-square Test for categorical variables. A total of 106 Turkmen patients with mean age of 64.22±12.12 (61 male and 45 female) were included in this study. Frequency for each ethnic group was identified as: Ahtahbai (n = 31, 29.2%), Googlan (n = 30, 28.3%), Jafarbai (n = 27, 25.5%), others (n = 7, 6.6%) and unidentified ethnic group (n = 11,10.4%). The mean age and gender were not significantly different between these ethnic groups. Heterogeneity was found within Turkmen population, Ahthabai having least and Googlan highest esophageal cancer incidence rate. As esophageal cancer is very common in Turkmen population and with the high incidence rate in Googlan, this ethnic group needs to be more targeted for the esophageal cancer-screening programme. Further population-based studies can better explore possible factors in different Turkmen ethnic groups

Prevalence of goiter among schoolchildren from Gorgan, Iran, a decade after national iodine supplementation: Association with age, gender, and thyroperoxidase antibodies

Background: One decade after universal salt iodization in Iran, goiter prevalence, urinary iodine concentration (UIC) and thyroperoxidase antibody (TPOAb) values were assessed among schoolchildren in Gorgan, Iran. Methods: From 2003-2004, 500 girls and 900 boys aged 7-11 yr were evaluated for goiter by palpation. UIC was measured in 183 randomly-selected goitrous children. Serum TSH, T 4, and TPOAb were measured in 53 goitrous and 30 non-goitrous children with adequate UIC. Results: Goiter was detected in 370 (26.4%) children. Goiter was present in 31 % of girls and 17% of boys age 9 (p<0.012); 37% of girls and 20% of boys age 10 (p<0.003); and 52% of girls and 19% of boys age 11 (p<0.0001). Median (range) UIC for all goitrous children sampled was 190 (20-600) μg/l; 220 (30-590) in boys and 170 (20-600) in girls (p=0.001). Eight point seven percent of goitrous children and 22% of goitrous girls aged 10-11 had UIC<100 μg/l, while 47% of the goitrous children had UIC≥200 μg/l. TPOAb was present in 52.8% of goitrous children and 10% of non-goitrous children (p=0.0001 ). TPOAb was present in 53.9% of 10-11 and 22.7% of 7-9 yr old goitrous and non-goitrous children (p=0.003) with adequate UIC. Median (range) TSH was 2.9 (0.3-10.9) mlU/l in TPO-positive and 1.8 (0.5-4.1) in TPO-negative children (p=0.001 ). Conclusions: Gorgan, Iran, is an iodine-sufficient area and almost half of schoolchildren have more than adequate UIC. TPOAb is associated with endemic goiter. Despite sufficient UIC overall, some school-aged girls remain at risk of iodine deficiency. ©2005, Editrice Kurtis

The french maritime pine bark extract reduce metabolic syndrome risk and improve body composition in obesity: A new clinical approach

Metabolic syndrome is a cluster of conditions which enhance the risk of metabolic and cardiovascular diseases such as diabetes mellitus, dyslipidemia, or hypertension. Obesity plays a pivotal role in the pathogenesis of metabolic syndrome. French maritime Pine bark extract (PBE) in addition to its antioxidant properties, has protective effects on metabolic syndrome component through several mechanisms. At present, there are few data on the net impact of PBE on metabolic syndrome factors in obesity. This trial report the results of 2-month period supplementation of 38 obese women received weight loss diet and PBE (150mg/day) or placebo. The metabolic syndrome parameters and body composition were assessed at the beginning and end of the study. The results showed PBE has significant protective effects on metabolic syndrome factors including central obesity, TG, HDL, BP and FBS (P<0.05), decrease metabolic syndrome risk in obesity and improve body composition. Thus, The PBE is considered as a new approach to obesity and metabolic syndrome prevention. © 2018 Tehran University of Medical Sciences. All rights reserved

Promoting menstrual health among persian adolescent girls from low socioeconomic backgrounds: a quasi-experimental study

<p>Abstract</p> <p>Background</p> <p>Research in the past decade has revealed average to poor menstrual health among many Iranian girls. The present study investigated the effectiveness of a health promotion project on improving menstrual health in adolescent girls in Iran.</p> <p>Methods</p> <p>A quasi-experimental study was conducted to evaluate the effectiveness of the health intervention program. A total of 698 students (study participants and controls) in several schools in Mazandaran province, Iran were included. The project comprised 10 two-hour educational sessions. Educational topics included the significance of adolescence, physical and emotional changes during adolescence, pubertal and menstruation health and premenstrual syndrome. A self-administered questionnaire measuring demographic characteristics, behaviors during menstruation, menstrual patterns, sources of information about menstruation and personal health data was administered. The questionnaire was administered to all participating students after the experimental group received the training.</p> <p>Results</p> <p>Among the most significant results was the impact of educational sessions on bathing and genital hygiene. A total of 61.6% in the experimental group compared with 49.3% in the control group engaged in usual bathing during menstruation (p = 0.002). Individual health status was significantly statistically correlated with menstrual health. Attitude towards menstruation was also significantly related to menstrual health.</p> <p>Conclusions</p> <p>The present study confirms that educational interventions, such as the health promotion project in this study, can be quite effective in promoting menstrual health.</p

NOX4-derived ROS are neuroprotective by balancing intracellular calcium stores

Hyperexcitability is associated with neuronal dysfunction, cellular death, and consequently neurodegeneration. Redox disbalance can contribute to hyperexcitation and increased reactive oxygen species (ROS) levels are observed in various neurological diseases. NOX4 is an NADPH oxidase known to produce ROS and might have a regulating function during oxidative stress. We, therefore, aimed to determine the role of NOX4 on neuronal firing, hyperexcitability, and hyperexcitability-induced changes in neural network function. Using a multidimensional approach of an in vivo model of hyperexcitability, proteomic analysis, and cellular function analysis of ROS, mitochondrial integrity, and calcium levels, we demonstrate that NOX4 is neuroprotective by regulating ROS and calcium homeostasis and thereby preventing hyperexcitability and consequently neuronal death. These results implicate NOX4 as a potential redox regulator that is beneficial in hyperexcitability and thereby might have an important role in neurodegeneration.</p
