Shervin Assari
2015, 6:53 (17 June 2015)
DOI

PMID
:26180624
Background:
This study aimed to investigate the additive effects of socio-economic factors, number of psychiatric disorders, and religiosity on suicidal ideation among Blacks, based on the intersection of ethnicity and gender.
Methods:
With a cross-sectional design, data came from the National Survey of American Life, 2001-2003, which included 3570 African-American and 1621 Caribbean Black adults. Socio-demographics, perceived religiosity, number of lifetime psychiatric disorders and lifetime suicidal ideation were measured. Logistic regressions were fitted specific to groups based on the intersection of gender and ethnicity, while socioeconomics, number of life time psychiatric disorders, and subjective religiosity were independent variables, and lifetime serious suicidal ideation was the dependent variable.
Results:
Irrespective of ethnicity and gender, number of lifetime psychiatric disorders was a risk factor for lifetime suicidal ideation (odds ratio [OR] ranging from 2.4 for Caribbean Black women to 6.0 for Caribbean Black men). Only among African-American men (OR = 0.8, 95% confidence interval = 0.7-0.9), perceived religiosity had a residual protective effect against suicidal ideation above and beyond number of lifetime psychiatric disorders. The direction of the effect of education on suicidal ideating also varied based on the group.
Conclusions:
Residual protective effect of subjective religiosity in the presence of psychiatric disorders on suicidal ideation among Blacks depends on ethnicity and gender. African-American men with multiple psychiatric disorders and low religiosity are at very high risk for suicidal ideation.

Background:
This paper presents the methodology and early findings of the fifth survey of a school-based surveillance program in Iran.
Methods:
This nationwide study was conducted in 2015 as the fifth survey of a surveillance program entitled "Childhood and Adolescence Surveillance and PreventIon of Adult Non- communicable disease" (CASPIAN-V) study. The protocol was mainly based on the World Health Organization-Global School student Health Survey. We studied 14400 students, aged 7-18 years, and their parents living in 30 provinces in Iran. Fasting blood was obtained from a sub-sample of 4200 randomly selected students.
Results:
The participation rate for the whole study and for blood sampling were 99% and 91.5%, respectively. The mean (SD) age of participants was 12.3 (3.2) years, consisting of 49.4% girls and 71.4% urban residents. Overall, 16.1% were underweight (17.4% of boys and 14.8% of girls), and 20.8% had excess weight consisting of 9.4% (8.7% of boys and 10.2% of girls) of overweight and 11.4% (12.5% of boys and 10.3% of girls) of obesity. Abdominal obesity was documented in 21.1% of students (21.6% of boys and 20.5% of girls). Low HDL-C was the most prevalent abnormality of the lipid profile (29.5%) followed by high serum triglycerides (27.7%). Of students, 59.9% consumed whole wheat bread; and 57% reported that they never or rarely added salt to table. The reported daily consumption of fresh fruits, vegetables, and milk was about 60%, 32% and 40%, respectively. 13.7% of participants had at least 30-min daily leisure-time physical activity.
Conclusions:
The current findings provide an overview of the current health status and lifestyle habits of children and adolescents. This surveillance program would help planning preventive programs at individual and community levels.

REVIEW ARTICLES
The effect of diabetes mellitus on apoptosis in hippocampus: Cellular and molecular aspects
Akram Sadeghi, Javad Hami, Shahnaz Razavi, Ebrahim Esfandiary, Zahra Hejazi
2016, 7:57 (10 March 2016)
DOI
:10.4103/2008-7802.178531
PMID
:27076895
Background:
Diabetes mellitus is associated with cognitive deficits in humans and animals. These deficits are paralleled by neurophysiological and structural changes in brain. In diabetic animals, impairments of spatial learning, memory, and cognition occur in association with distinct changes in hippocampus, a key brain area for many forms of learning and memory and are particularly sensitive to changes in glucose homeostasis. However, the multifactorial pathogenesis of diabetic encephalopathy is not yet completely understood. Apoptosis plays a crucial role in diabetes-induce neuronal loss in hippocampus.
Methods:
The effects of diabetes on hippocampus and cognitive/behavioral dysfunctions in experimental models of diabetes are reviewed, with a focus on the negative impact on increased neuronal apoptosis and related cellular and molecular mechanisms.
Results:
Of all articles that were assessed, most of the experimental studies clearly showed that diabetes causes neuronal apoptosis in hippocampus through multiple mechanisms, including oxidative stress, inhibition of caspases, disturbance in expression of apoptosis regulator genes, as well as deficits in mitochondrial function. The balance between pro-apoptotic and anti-apoptotic signaling may determine the neuronal apoptotic outcome
in vitro
and
in vivo
models of experimental diabetes.
Conclusions:
Dissecting out the mechanisms responsible for diabetes-related changes in the hippocampal cell apoptosis helps improve treatment of impaired cognitive and memory functions in diabetic individuals.

2015, 6:3 (15 January 2015)
DOI
:10.4103/2008-7802.151433
PMID
:25789138
Background:
The purpose of this study was to evaluate the validity and reliability on the Persian translation of the Modifiable Activity Questionnaire (MAQ) in a sample of Tehranian adolescents.
Methods:
Of a total of 52 subjects, a sub-sample of 40 participations (55.0% boys) was used to assess the reliability and the validity of the physical activity questionnaire. The reliability of the two MAQs was calculated by intraclass correlation coefficients, and validation was evaluated using Pearson correlation coefficients to compare data between mean of the two MAQs and mean of four physical activity records.
Results:
Intraclass correlation coefficient was calculated to assess the reliability between two MAQs and the results of leisure time physical activity over the past year were 0.97. Pearson correlation coefficients between mean of two MAQs and mean of four physical activity records were 0.49 (
P
< 0.001), for leisure time physical activities.
Conclusions:
High reliability and relatively moderate validity were found for the Persian translation of the MAQ in a Tehranian adolescent population. Further studies with large sample size are suggested to assess the validity more precisely.

Effectiveness of school-based interventions to prevent or control overweight and obesity among school children was reviewed for a 11-year period (January 2001 to December 2011). All English systematic reviews, meta-analyses, reviews of reviews, policy briefs and reports targeting children and adolescents which included interventional studies with a control group and aimed to prevent or control overweight and/or obesity in a school setting were searched. Four systematic reviews and four meta-analyses met the eligibility criteria and were included in the review. Results of the review indicated that implementation of multi-component interventions did not necessarily improve the anthropometric outcomes. Although intervention duration is a crucial determinant of effectiveness, studies to assess the length of time required are lacking. Due to existing differences between girls and boys in responding to the elements of the programs in tailoring of school-based interventions, the differences should be taken into consideration. While nontargeted interventions may have an impact on a large population, intervention specifically aiming at children will be more effective for at-risk ones. Intervention programs for children were required to report any unwanted psychological or physical adverse effects originating from the intervention. Body mass index was the most popular indicator used for evaluating the childhood obesity prevention or treatment trials; nonetheless, relying on it as the only indicator for adiposity outcomes could be misleading. Few studies mentioned the psychological theories of behavior change they applied. Recommendations for further studies on school-based interventions to prevent or control overweight/obesity are made at the end of this review.

PMID
:25949777
Background:
Polycystic ovary syndrome (PCOS) is a polygenic endocrine disorder in women of reproductive age that lead to infertility. The aim of this study was to investigate the effects of probiotic on pancreatic b-cell function and C-reactive protein (CRP) in PCOS patients.
Methods:
This randomized double-blind placebo-controlled clinical trial was conducted among 72 women aged 15-40 years old diagnosed with PCOS. Participants were randomly assigned to two groups receiving: (1) Probiotic supplements (
n
= 36), (2) placebo (
n
= 36) for 8-week. Fasting blood samples were taken at baseline and after 8-week of intervention.
Results:
Probiotic supplementation, compare with placebo, reduced fasting blood sugar (−4.15 ± 2.87 vs. 2.57 ± 5.66 mg/dL, respectively
P
= 0.7), serum insulin levels in crude model (−0.49 ± 0.67 vs. 0.34 ± 0.82 mIU/mL, respectively,
P
= 0.09), homeostasis model of assessment-insulin resistance score (−0.25 ± 0.18 vs. −0.05 ± 0.18, respectively,
P
= 0.14) nonsignificantly. Serum insulin levels after adjustment with covariates reduced significantly in probiotic group (
P
= 0.02). We did not found any significant differences in mean changes of CRP between groups (−0.25 ± 0.18 vs. −0.05 ± 0.18, respectively,
P
= 0.14).
Conclusions:
A 8-week multispecies probiotics supplementation had nonsignificantly beneficial effect on pancreatic b-cell function and CRP in PCOS patients. After adjustment for some covariates, serum insulin changes were significantly different between groups.

Does multi-morbidity mediate the effect of socioeconomics on self-rated health? cross-country differences
Shervin Assari, Maryam Moghani Lankarani
2015, 6:85 (3 September 2015)
DOI
:10.4103/2008-7802.164413
PMID
:26445632
Background:
This study explored cross-country differences in how multi-morbidity explains the effects of socioeconomic characteristics on self-rated health.
Methods:
The study borrowed data from the Research on Early Life and Aging Trends and Effects. Participants were 44,530 individuals (age > 65 years) who were sampled from 15 countries (i.e. United States, China, India, Russia, Costa Rica, Puerto Rico, Mexico, Argentina, Barbados, Brazil, Chile, Cuba, Uruguay, Ghana and South Africa). Multi-morbidity was measured as number of chronic medical conditions. In Model I, main effects of socioeconomic factors on self-rated health were calculated using country-specific logistic regressions. In Model II, number of chronic conditions were also added to the models to find changes in coefficients for demographic and socioeconomic factors.
Results:
In the United States, number of chronic medical conditions explained the effect of income on subjective health. In Puerto Rico, number of chronic medical conditions explained the effect of marital status on subjective health. In Costa Rica, Argentina, Barbados, Cuba, and Uruguay, number of chronic medical conditions explained gender disparities in subjective health. In China, Mexico, Brazil, Russia, Chile, India, Ghana and South Africa, number of chronic medical conditions did not explain the effect of demographic or socioeconomic factors on subjective health.
Conclusions:
Multi-morbidity explains the effect of demographic and socioeconomic factors on subjective health in some but not other countries. Further research is needed.

PMID
:26955458
Background:
Green tea is one of the most popular beverages in the world. It is believed to have beneficial effects in the prevention and treatment of many diseases, one of which is nonalcoholic fatty liver disease (NAFLD). The present study investigated the effects of consumption of green tea in NAFLD patients.
Methods:
This study was a double-blind, placebo-controlled, randomized clinical trial. Ultrasonography was used to diagnose fatty liver in patients with alanine aminotransferase (ALT) >31 mg/dl and 41 mg/dl and aspartate aminotransferase (AST) >31 mg/dl and 47 g/dl in women and men, respectively and without other hepatic diseases. A total of 80 participants (20-50 years) with NAFLD were randomly allocated into two groups to receive either green tea extract (GTE) supplement (500 mg GTE tablet per day) or placebo for 90 days. At baseline and at the end of the intervention weight, serum ALT, AST, and alkaline phosphatase (ALP) were measured in fasting state, and dietary data were collected at baseline and end of the study.
Results:
Green tea group showed significant reductions in ALT and AST levels after 12 weeks period (
P
< 0.001). The placebo group showed a reduction in ALT and AST levels at the end of the study, but it was no significant. ALP levels showed significant reductions in both groups after 12 weeks period (
P
< 0.001).
Conclusions:
According to the findings of this study, GTE supplementation decrease liver enzymes in patients with NAFLD. It can be claimed that GTE prescribed can be considered as a treatment to improve serum levels of liver enzymes in NAFLD patients.

PMID
:27076897
Background:
Regarding to the growing prevalence of nonalcoholic fatty liver disease (NAFLD), concentrating on various strategies to its prevention and management seems necessary. The aim of this study was to determine the effects of symbiotic on C-reactive protein (CRP), liver enzymes, and ultrasound findings in patients with NAFLD.
Methods:
Eighty NAFLD patients were enrolled in this randomized, double-blind, placebo-controlled clinical trial. Participants received symbiotic in form of a 500 mg capsule (containing seven species of probiotic bacteria and fructooligosaccharides) or a placebo capsule daily for 8 weeks. Ultrasound grading, CRP, and liver enzymes were evaluated at the baseline and the end of the study.
Results:
In the symbiotic group, ultrasound grade decreased significantly compared to baseline (
P
< 0.005) but symbiotic supplementation was not associated with changes in alanine aminotransferase (ALT) and aspartate transaminase (AST) levels. In the placebo group, there was no significant change in steatosis grade whereas ALT and AST levels were significantly increased (
P
= 0.002,
P
= 0.02, respectively). CRP values remained static in either group.
Conclusions:
Symbiotic supplementation improved steatosis in NAFLD patients and might be useful in the management of NAFLD or protective against its progression.

DOI
:10.4103/2008-7802.180412
PMID
:27141285
Background:
Nigella sativa
has been a nutritional flavoring factor and natural treatment for many ailments for so many years in medical science. Earlier studies have been reported that thymoquinone (TQ), an active compound of its seed, contains anticancer properties. Previous studies have shown that TQ induces apoptosis in breast cancer cells but it is unclear the role of P53 in the apoptotic pathway. Hereby, this study reports the potency of TQ on expression of tumor suppressor gene P53 and apoptosis induction in breast cancer cell line Michigan Cancer Foundation-7 (MCF-7).
Methods:
MCF-7 cell line was cultured and treated with TQ, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was carried out for evaluating the half-maximal inhibitory concentration (IC50) values after 24 h of treatment. The percentage of apoptotic cells was measured by flow cytometry. Real-time polymerase chain reaction (PCR) was performed to estimate the messenger RNA expression of P53 in MCF-7 cell line at different times.
Results:
The IC50 value for the TQ in MCF-7 cells was 25 mM that determined using MTT assay. The flow cytometry and real-time PCR results showed that TQ could induce apoptosis in MCF-7 cells, and the P53 gene expression was dramatically up-regulated by ascending time, respectively. Hence, there was significant difference in 48 and 72 h.
Conclusions:
Our results demonstrated that TQ could induce apoptosis in MCF-7 cells through up-regulation of P53 expression in breast cancer cell line (MCF-7) by time-dependent manner.

Is waist circumference a better predictor of diabetes than body mass index or waist-to-height ratio in Iranian adults?
Karimollah Hajian-Tilaki, Bezad Heidari
2015, 6:5 (15 January 2015)
DOI
:10.4103/2008-7802.151434
PMID
:25789140
Background:
Several measures of adiposity have been used for predicting diabetes. The results of studies regarding superiority of waist circumference (WC) to body mass index (BMI) are inconsistent. This study designed to compare the ability of different anthropometric measures in predicting diabetes and to determine their optimal cut-off values.
Methods:
A population-based cross-sectional study was conducted with 1,000 representative sample among adults aged 20-80 years in Babol, the Northern Iran. The demographic data were collected in a household survey, and the anthropometric measures of weight, height, waist, and hip circumference were measured with a standard method. Fasting blood sugar (FBS) ≥126 mg/dl was considered as diabetes. receiver operating characteristic analysis was used to estimate the predictive ability of different anthropometric indexes and their optimal cut-off values for high FBS.
Results:
The overall prevalence rate of diabetes was 14.0% (14.4% in men vs. 13.5% in women,
P
= 0.65). The prevalence rate was significantly higher in older age (>60 years), low educated and obese (
P
= 0.001). The mean of BMI, WC, waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) were significantly higher among diabetic in both sexes (
P
= 0.001). Among men, WC (area under the ROC curve [AUC] =0.64) and WHtR (AUC = 0.63) have slightly higher accuracy index compared with BMI (AUC = 0.62) or WHR (AUC = 0.60). In contrast, among women, WHtR (AUC = 0.69) and WC (AUC = 0.68) yielded slightly better predictive than BMI (AUC = 0.67). The optimal cut-off values obtained for BMI and WHtR were similar between two sexes (BMI = 24.95 kg/m
2
for men and BMI = 25.2 kg/m
2
for women, WHtR = 0.51 for both sexes) whereas the optimal cut-off value for WC was higher in men than women (98.5 cm men vs. 89.5 cm women).
Conclusions:
Overall WC and WHtR exhibited a slightly better discriminate performance than BMI for diabetes in both sexes, particularly in women.

REVIEW ARTICLES
Magnesium, iron, and zinc supplementation for the treatment of attention deficit hyperactivity disorder: A systematic review on the recent literature
Mitra Hariri, Leila Azadbakht
2015, 6:83 (2 September 2015)
DOI
:10.4103/2008-7802.164313
PMID
:26445630
Background:
The etiology of attention deficit hyperactivity disorder (ADHD) is not exactly known and its etiology is multifactorial. The usual treatment for these children is based on pharmacotherapy treatment, although the pharmacotherapy has a high effectiveness in ADHD treatment, it often causes different side effects. Existing evidence suggests that children who receive mineral supplement without considering their age and supplement formula may perform better on different behavioral tests compared with those receiving placebo.
Methods:
In this study, we tried to review the previous evidence regarding the effects of minerals in prevention and management of ADHD. We searched PubMed/Medline, Google Scholar, Ovid, Scopus, and ISI web of science up to June 2013. "iron," "iron supplementation," "magnesium," "magnesium supplementation," "zinc," "zinc supplementation," "attention deficit hyperactivity disorder" were used as the keywords. Totally 11 randomized controlled trials were eligible to be included in the systematic review.
Results:
Our review showed that we don't have any predominant evidence about using mineral supplementation on children with ADHD.
Conclusions:
We need more evidence for indicating the effect of zinc, magnesium, and iron supplementation in the treatment of ADHD among children.

Tobacco smoking is one of the greatest causes of mortality in the world, responsible for over 5 million deaths per annum. The prevalence of smoking is over 1 billion people, with the majority coming from low or middle income countries. Yet, the incidence of smoking varies vastly between many countries. Some countries have been able to decline the smoking and tobacco related morbidity and mortality through the introduction of health promotion initiatives and effective policies in order to combat tobacco usage. However, on the other hand, in some countries, the incidence of smoking is increasing still further. With the growing body of evidence of detriment of tobacco to health, many control policies have been implemented as health promotion actions. Such methods include taxation of smoking, mass advertising campaigns in the media, peer education programs, community mobilization, motivational interviewing, health warnings on tobacco products, marketing restrictions, and banning smoking in public places. However, the review of the effectiveness of various health promotion methods used for smoking prevention and cessation is lacking. Therefore, the aim of this review is to identify and critically review the effectiveness of health promotion methods used for smoking prevention and cessation. All available studies and reports published were considered. Searches were conducted using PubMed, MEDLINE, Ovid, Karger, ProQuest, Sage Journals, Science Direct, Springer, Taylor and Francis, EMBASE, CINAHL, and Cochrane and Wiley Online Library. Various relevant search terms and keywords were used. After considering the inclusion and exclusion criteria, we selected 23 articles for the present review.

Background:
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the world. Although some studies have been conducted about dietary intakes of these patients, but the results are inconsistent. The aim of this study was to survey all macronutrients and micronutrients included in dietary intake of these patients for better understanding the factors influencing this disease.
Methods:
The present study is a case-control conducted in Isfahan city, Iran. The cases were recently diagnosed patients with NAFLD who identified by ultrasonography. The case (159) and control (158) individuals were matched in age and gender. Data of general characteristics and physical activity of individuals were collected through questionnaire. Dietary intake was also collected using 24 h dietary recall questionnaire.
Results:
Waistline and body mass index for the case group were more than the control group (
P
< 0.05). Physical activity level in healthy individuals was more than patients with NAFLD. Dietary intake of saturated fatty acids and sugar in patients with NAFLD was more than healthy individuals (
P
< 0.05). Intake of total dietary fiber, folic acid, Vitamin D, zinc, and potassium in healthy individuals was more than patients with NAFLD (
P
< 0.05).
Conclusions:
In total, it seems the type of dietary intake source is associated with NAFLD. Increasing saturated fatty acids and sugar and decreasing fiber, folic acid, Vitamin D, zinc, and potassium intake might play a role in the progression of this disease.

Background:
Control of blood sugar, hypertension, and dyslipidemia are key factors in diabetes management.
Cucurbita ficifolia
(pumpkin) is a vegetable which has been used traditionally as a remedy for diabetes in Iran. In addition, consumption of probiotics may have beneficial effects on people with Type 2 diabetes. The aim of this study was an investigation of the effects of
C. ficifolia
and probiotic yogurt consumption alone or at the same time on blood glucose and serum lipids in diabetic patients.
Methods:
Eighty eligible participants randomly were assigned to four groups: 1 - green
C. ficifolia
(100 g); 2 - probiotic yogurt (150 g); 3 -
C. ficifolia
plus probiotic yogurt (100 g
C. ficifolia
plus 150 g yogurt); and 4 -control (dietary advice) for 8 weeks. Blood pressure, glycemic response, lipid profile, and high-sensitive C-reactive protein (hsCRP) were measured before and after the intervention.
Results:
Total cholesterol (TC) decreased significantly in yogurt and yogurt plus
C. ficifolia
groups (within groups
P
= 0.010, and
P
< 0.001, respectively).
C. ficifolia
plus yogurt consumption resulted in a decrease in triglyceride (TG) and an increase in high-density lipoprotein cholesterol (HDL-C) (within groups
P
< 0.001 and
P
= 0.001, respectively). All interventions led to a significant decrease in blood sugar, hemoglobin A1c (HbA1c), hsCRP, and low-density lipoprotein cholesterol (LDL-C) level within groups. Blood pressure decreased significantly in Cucurbita group and yogurt group (within groups
P
< 0.001, and
P
= 0.001 for systolic blood pressure [SBP] and
P
< 0.001, and
P
= 0.004 for diastolic blood pressure [DBP], respectively). All variables changed between groups significantly except LDL-C level.
Conclusions:
Variables including TG, HDL-C, TC, fasting blood sugar, HbA1c, SBP, DBP, and hsCRP changed beneficially between groups. It seems that consumption of
C. ficifolia
and probiotic yogurt may help treatment of diabetic patients.

PMID
:26445636
Background:
Hepatitis C virus (HCV) is the leading cause of transfusion transmitted infections (TTIs) among patients with b-thalassemia major. A high prevalence of HCV was reported among these patients. The aim of this study is seeking the trend of the prevalence of HCV infection among the patients with b-thalassemia major in Guilan province, Northern Iran over a 10-year period.
Methods:
A retrospective study was conducted on 1113 patients with b-thalassemia major in the Guilan province, northern Iran from 2002 to 2012, using multiple data sources. A blood sample was taken from each patient, and a questionnaire regarding demographic data and risk factors was completed for them. Enzyme-linked immunosorbent assay and recombinant immunoblot assay for HCV were performed in all cases. A stepwise forward logistic regression analysis was done.
Results:
The prevalence of hepatitis C infection among b-thalassemia major patients was 13.6%. The risk of hepatitis C among b-thalassemia major patients was greater before screening program for HCV (odds ratio = 9.6, 95% confidence interval: 2.3-40.5). In addition, the prevalence of anti-HCV seropositivity was decreased dramatically among patients who have received transfusions after implementation of blood donor screening for HCV. There were no positive HCV cases in the patients younger than 10 years.
Conclusions:
The risk of TTIs including HCV can be reduced by implementing screening program for healthy blood.

PMID
:27141284
Background:
Healthy lifestyle is a major strategy to promote current and subsequent health status. The aim of this study was to assess the status of health-promoting the lifestyle and its determinants among students.
Methods:
A stratified random sample of 500 students in a university in the city of Sabzevar, Iran participated in this cross-sectional study. Health-promoting lifestyle was measured using Walker's health-promoting lifestyle profile II.
Results:
There was a significant correlation between all domains of health-promoting the lifestyle. The highest score among the domains was for an interpersonal relationship (70.8%), and the lowest score was for nutrition (53.6%), and physical activity (53.4%). Significant differences were found in physical activity by gender (
P
≤ 0.05). There were significant differences in health responsibility, spiritual growth and body mass index by marital status (
P
< 0.01).
Conclusions:
Since one out of five students in this study were overweight/obese, health program planning to promote lifestyle, especially physical activity and nutrition among students is recommended. Our findings may be helpful for faculty administrators, curriculum planners, and health educators in designing guidelines to structuralize a healthier campus and to develop health promotion programs supporting healthy choices among students.

Leishmaniasis is considered as a zoonotic infection and neglected tropical disease.
Leishmania
treatment is not totally successful and imposes high expenditures, especially in developing countries. Since the natural infection leads to the robust immunity in most of the human cases, many bodies of research have been focusing on
Leishmania
vaccines, being capable to control
Leishmania
infection. First generation vaccines (such as Leishmune
®
and CaniLeish
®
) have proved robust protective immunity in dogs. In human, recombinant vaccines, including Leish-F1 could confer some degrees of protective immunity against natural infection. Recently, ChAd63-KH DNA vaccine has been accomplished in providing prevention against
Leishmania
infection; however, this vaccine should be further evaluated in other clinical trials.

Background:
This paper presents the methodology and primary findings of a national project on determinants of weight disorders among Iranian children and adolescents at national and sub-national levels.
Methods:
This nationwide study was conducted in 2011-2012 in Iran as part of the fourth phase of a national surveillance program entitled Childhood and Adolescence Surveillance and PreventIon of Adult Noncommunicable disease-IV study. It had two phases of qualitative and quantitative study. This multicentric study was conducted among 25,000 students aged 6-18 years, living in urban and rural areas of 30 provinces of Iran. Students were selected by multistage cluster sampling method. Data regarding weight disorders including sociodemographic variables, perinatal factors, lifestyle factors, family and student dietary habits, quality of life, and family history of chronic diseases as well as body image were gathered via validated questionnaires.
Results:
Overall, 23043 students completed the survey (participation rate: 92.17%). The mean age of participants was 12.55 ± 3.31 years; 50.8% were boys, and 73.4% were from urban areas. Underweight was found in 10.4% of boys and 9.2% of girls, the corresponding figure for overweight and obesity was 21% and 18.3%. Abdominal obesity was found in 17.6% of students. Among parents, obesity was more frequent than other weight disorders, with higher prevalence in parents of girls than boys (24.5% vs. 21.5%, respectively,
P
< 0.001). Overweight and obesity were more prevalent in urban than in rural parents (66.7% vs. 59.7%, respectively,
P
< 0.001).
Conclusions:
This survey serves as confirmatory evidence on the prevalence of dual burden of weight disorders in Iran. Its findings on determinants of weight disorders would help policymakers to implement relevant programs at national and sub-national levels.

2017, 8:19 (6 April 2017)
DOI
:10.4103/ijpvm.IJPVM_144_17
PMID
:28479961
Background:
Various epidemiological studies have shown that exposure to environmental pollutants including polycyclic aromatic hydrocarbons (PAHs) might increase the risk of cardiovascular diseases (CVDs) and their risk factors. This study aims to systematically review the association of PAH exposure with metabolic impairment.
Methods:
Data were collected by searching for relevant studies in international databases using the following keywords: “polycyclic aromatic hydrocarbon” + “cardiovascular disease,” PAH + CVD, polycyclic aromatic hydrocarbon and “air pollutant” + “CVD,” and the desired data were extracted and included in the study according to the systematic review process.
Results:
From the 14 articles included in the present systematic review, eight articles were conducted on the relationship between PAH and CVDs, four articles were conducted to examine the association of PAH exposure with blood pressure (BP), and two articles investigated the link between PAH and obesity.
Conclusions:
Most studies included in this systematic review reported a significant positive association of PAH exposure with increased risk of CVDs and its major risk factors including elevated BP and obesity. These findings should be confirmed by longitudinal studies with long-term follow-up.

Penile inflammatory skin conditions such as balanitis and posthitis are common, especially in uncircumcised males, and feature prominently in medical consultations. We conducted a systematic review of the medical literature on PubMed, EMBASE, and Cohrane databases using keywords “balanitis,” “posthitis,” “balanoposthitis,” “lichen sclerosus,” “penile inflammation,” and “inflammation penis,” along with “circumcision,” “circumcised,” and “uncircumcised.” Balanitis is the most common inflammatory disease of the penis. The accumulation of yeasts and other microorganisms under the foreskin contributes to inflammation of the surrounding penile tissue. The clinical presentation of inflammatory penile conditions includes itching, tenderness, and pain. Penile inflammation is responsible for significant morbidity, including acquired phimosis, balanoposthitis, and lichen sclerosus. Medical treatment can be challenging and a cost burden to the health system. Reducing prevalence is therefore important. While topical antifungal creams can be used, usually accompanied by advice on hygiene, the definitive treatment is circumcision. Data from meta-analyses showed that circumcised males have a 68% lower prevalence of balanitis than uncircumcised males and that balanitis is accompanied by a 3.8-fold increase in risk of penile cancer. Because of the high prevalence and morbidity of penile inflammation, especially in immunocompromised and diabetic patients, circumcision should be more widely adopted globally and is best performed early in infancy.

Helicobacter pylori
infection is a common health problem related to many gastrointestinal disorders. This study aims to estimate the total and age specific prevalence of
Helicobacter Pylori
infection in Iran. We systematically reviewed all national and international databases and finally identified 21 studies were eligible for meta-analysis. Each of them were assigned a quality score using STROBE checklist. Due to significant heterogeneity of the results, random effects model was used to estimate the pooled prevalence and 95% confidence interval of
Helicobacter Pylori
infection. All statistical analyses were performed using STATA. V11 software. The pooled prevalence (95% confidence interval) of
Helicobacter Pylori
infection among all population, children and adults were estimated as 54% (53%- 55%), 42% (41%- 44%) and 62% (61%- 64%) respectively.
Helicobacter Pylori
, has infected more than half of Iranian people during the last decade. Preventive strategies as well as taking into account this infection during clinical visits should be emphasized to reduce its transmission and prevalence within the community.
