Reports have shown that lipoprotein (Lp)(a) can serve as an indicator of atherosclerosis and cardiovascular diseases. Several cardiovascular disease risk factors including age, ethnicity and type 2 diabetes mellitus have been linked to Lp(a) metabolism. Given the structural similarity between Lp(a) and plasminogen, there may be a relationship between Lp(a) level and thrombosis and atherogenesis. In this review, we summarize the latest data about Lp(a) and related conditions on the PubMed database using the following keywords: “Lp(a) and diseases” and “Lp(a) and racial groups”. All available information was extracted and categorized according to the purpose of this study. In conclusion, evidence suggest that increased level of Lp(a) results in coronary artery disease and increases the risk of ischemic stroke. Lack of Lp(a) has no adverse effect on human health. Moreover, Lp(a) can be effective in wound healing as it degrades apolipoprotein(a) products which might have anti-tumor and anti-angiogenetic effects. Keywords: Lipoprotein(a), Atherosclerosis, Apo(a).

Background\ud Cardiovascular disease (CVD) is the most common cause of morbidity and mortality globally. Despite progress being made in the diagnosis and treatment of CVDs, one third of deaths are due to CVDs. We have investigated the association between the rs1333049 polymorphism of the cyclin-dependent kinase inhibitor 2A/B (CDKN2A/B) gene with CVD outcomes in a population sample recruited as part of the Mashhad-Stroke and Heart-Atherosclerotic-Disorders (MASHAD) cohort.\ud \ud Methods and results\ud Five hundred and nine individuals who had a median follow-up period of 10 years were recruited as part of the MASHAD cohort. Anthropometric, and biochemical parameters were assessed followed by genotyping using TaqMan-real-time-PCR based method. Our data showed that carriers of the GG genotype were significantly more likely to develop CVD, compared to those with a CC or CG genotypes (OR: 4.77, 95%CI: 2.62–8.68, p = 0.001). Similar result we also found in second population which were follow up for 10 years. In particular cases who had an event in recessive genetic model (CC vs CG + GG) had a higher risk of developing CVD (OR: 5.57, 95%CI: 2.80–11.06, p = 0.001).\ud \ud Conclusion\ud We have found that carriers of the GG genotype of the CDKN2A/B gene locus were at increased risk of CVD in a representative population-based cohort, indicating further functional analysis to explore the value of emerging marker as a risk stratification biomarker to identify high risk cases.

BACKGROUND: Cardiovascular disease is one of the most common causes of morbidity and mortality worldwide. The Proline and Serine Rich Coiled-Coil 1 gene in 1p13.3 locus has been reported to be associated with low density lipoprotein cholesterol (LDL-C) and coronary artery disease (CAD). The objective of this study was to investigate the association between the rs599839 polymorphism of the Proline and Serine Rich Coiled-Coil 1 (PSRC1) gene with CVD outcomes in a population sample recruited as part of the Mashhad-Stroke and Heart-Atherosclerotic-Disorders (MASHAD) cohort. METHODS: Five hundred and nine individuals who had an average follow-up period of 10 years were enrolled as part of the MASHAD cohort. DNA was extracted and genotyped using the TaqMan-real-time-PCR based method. RESULTS: The study found individuals with GA/GG genotypes were at a higher risk of CVDs (OR= 4.7; 95% CI, 2.5-8.7; p< 0.001) in comparison to those with AA genotype; however, the result was not significant for GG genotype data. CONCLUSION: The results suggest that the GA/GG genotypes of the PSRC1gene locus were at increased risk of CVD in a representative population-based cohort, demonstrating further functional analysis to discover the value of emerging marker as a risk stratification biomarker to recognize high risk cases.

Introduction: Coronary heart disease (CHD) is the leading cause of morbidity and mortality globally, and specially in Iran. An accurate assessment of the incidence of coronary heart disease (CHD) is very important for public health. In current study we aimed to investigate the incidence of CHD and importance of several classical modifiable and un-modifiable risk factors for CHD among an urban population in eastern Iran after 6 years follow-up. Methods: The population of MASHAD cohort study were followed up for 6 years, every 3 years initially by phone and those who reported symptoms of cardiovascular disease (CVD) were asked to attend for a cardiac examination. An estimate of the incidence of CHD was determined with 95% confidence interval (95% CI) and multiple logistic regression analysis was performed to assess the association of several baseline characteristics with the incidence of a CHD event. Evaluation of goodness-of-fit was undertaken using ROC analysis. CHD cases were divided into four different categories: stable angina, unstable angina pectoris, myocardial infarction and sudden cardiac death. Results: In the six years of follow-up of the Mashhad study participants, the incidence density of CHD events in men and women in 1000 person-year with 95% confidence intervals were 19.20 (8.10-30.30) and 11.60 (7.30-15.90), respectively. The areas under ROC curve (AUC), based on multiple logistic regression model of CHD outcome, was determined to be 0.783. Conclusion: Our findings indicated that the incidence rate of coronary heart diseases in MASHAD cohort study increases with age, and our final model was able to predict approximately 78% of CHD events in this Iranian population.

Cardiovascular disease (CVD), one of the main mortality causes worldwide is considered to be affected by general oxidative stress and inadequacy antioxidant system. Superoxide dismutase 1 (SOD1), a cytosolic antioxidant enzyme has a key role in neutralizing the excessive prooxidant by scavenging the super oxide anions. SOD1 polymorphic variants exhibit the altered activity properties. In the current study, we are aimed to investigate the association between the SOD1 polymorphism and CVD prevalence. A 6-years case control follow up study was designed to genotype the 526 participants (311 controls and 215 cases) for studying the 50 bp INS/DEL polymorphism at SOD1 promoter gene and analyze their blood lipid profile and anthropometric characteristics. Among the two possible alleles of the SOD1 gene (Wild [W] and Mutant [M]) the meaningful association was detected between the Mutants' frequency and the prevalence of CVD patients (p-value

The dietary inflammatory index (DII) is a novel way of describing diet that has been studied in relation to various health conditions, including cardiovascular disease (CVD) in several populations. We aimed to investigate the association between DII and CVD events among a representative population sample in northeastern Iran. This prospective cohort study was a subsample of 4,672 adults aged 35-65 years, and recruited as part of Mashhad stroke and heart atherosclerotic disorder cohort study population. The DII was computed at baseline according to a 65-item validated food frequency questionnaire. Cox regression was used to determine the association of DII with incident CVD. One hundred twenty-four participants developed CVD (including 24 cases of myocardial infarction [MI], 34 cases of stable angina [SA], and 66 cases of unstable angina [UA]). After adjusting for potential confounding factors, a hazard ratios of 1.06 (95% confidence interval: 0.70-1.60), 1.36 (95% confidence interval: 0.52-3.52), 1.33 (95% confidence interval: 0.60-2.94), and 0.86 (95% confidence interval: 0.48-1.53) were found for total CVD, MI, SA, and UA events, respectively, among the participants with proinflammatory diet (DII ≥ 0) versus those with anti-inflammatory diet (DII < 0). There was no statistically significant association between the DII and total CVD, MI, SA, or UA in this population of middle-aged Iranian men and women.

Objective Postmenopausal women are at an increased risk of Cardiovascular Disease. We aimed to investigate whether this risk differed between individuals with a naturally occurring and other reasons for menopause within a large population-based Iranian sample. Study Design A total number of 1763 postmenopausal women (defined by amenorrhea for more than a year, or FSH > 30-40 mIU/ml), 900 of them with a natural menopause and 863 of them with other reasons for menopause caused by (hysterectomy without oophorectomy or one side oophorectomy, hysterectomy with oophorectomy or two side oophorectomy without hysterectomy) were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. Biochemical and hematological risk factors were measured in all the subjects and the data were analyzed by SPSS software version 20 Results There was a significant difference in the presence of cardiovascular disease in the natural menopause group compared with other reasons for menopause group (p

Background: Heat shock protein 27 (HSP27) is an intracellular chaperone constitutively expressed in many cell types including cardio myocytes and endothelial cells. Circulating levels of HSP27 and anti-HSP27 antibody are higher in patients with CVD. Anti-HSP27 antibody concentrations were also reported to be increased in atherogenesis. We aimed to evaluate serum anti-HSP27 antibody titers in individuals with, or without, MetS in the MASHAD study cohort with large sample size in 6,568 subjects. Methods: Participants with MetS were identified from MASHAD cohort (n=3358) using the IDF criteria, and the control group were those individuals who did not meet these criteria (n=3210). In-house enzyme-linked immune sorbent assay (ELISA) method was used for measuring Anti-HSP27 antibody levels. The two groups were matched for age, sex and smoking habit. Results: As expected, there were significant differences in height (p= 0.004), waist and hip circumference, weight, BMI, systolic and diastolic blood pressure, TGs, TC, HDL-C, Hs-CRP, glucose, with the presence of diabetes mellitus, hypertension, hyperlipidemia (p Conclusion: In conclusion, our results revealed serum anti-HSP27 antibody titers were not statistically different between individuals with and without MetS. However, it is possible that drug treatment may affect antibody titers and confound our findings in this population sample..

Background: Metabolic syndrome (MetS) is associated with an increased risk of cardiovascular disease and all-cause mortality. Zinc (Zn) is an essential trace element for the synthesis, storage, and release of insulin. The relationship between serum Zn and MetS is controversial. In this study we have evaluated whether serum Zn levels are associated with hsCRP level according to MetS phenotypes. Method: A total of 9493 individuals (3768 men and 5635 women) were recruited as part of the Mashhad Stroke and Heart Association Disorder (MASHAD) study. We measured the concentration of serum Zn by flame atomic absorption (Varian AA240FS) and we divided the subjects into quartile of serum Zn. We used SPSS version 18 statistical analyses for all. GraphPad Prism 6 for figures was used.Results: In this study there were significant differences between quartiles of Zn according to sex. The results showed that the level of serum hs-CRP were higher in subjects with metabolic syndrome who also had a serum Zn >95 µg/dl. In subjects with serum Zn Conclusion: Serum hs-CRP concentrations were related to MetS phenotypes. This relationship was modified by serum Zn level. According to the number of MetS components serum Zn levels decreased as the number of MetS component increased, and low serum zinc levels (Q1) showed an overall greater prevalence of MetS.

It has been shown that increased serum PON1 levels are protective against several disorders. Several single nucleotide polymorphisms (SNPs) of the PON1 gene have been reported to be associated with serum enzyme protein levels and activity.To investigate the association of SNPs of PON1 and serum paraoxonase activity with coronary artery disease (CAD).A total of 601 unrelated patients who underwent coronary angiography including those who hadgt;50% stenosis (N=266) and those withlt;30% stenosis (N=335) were studied. The Paraoxonase gene rs662 and rs840560 SNPs were determined using the ARMS-PCR method and the rs705379 SNP was genotyped using PCR-RFLP analysis. Serum paraoxonase activity was measured using paraoxon as a substrate. A p value of plt;0.05 was considered as significant.Serum paraoxonase activity was not significantly different between the study groups. After adjustment for age, sex, hypertension, diabetes mellitus and dyslipidemia, the GG genotype and co-dominant model of rs662 was positively associated with a positive angiogram (respectively, OR=2.424, 95%CI [1.123-5.233], plt;0.05, OR=1.663, 95%CI [1.086-2.547]). Serum paraoxonase activity was significantly higher in the G allele and GG variant of rs662, A allele and AA variant of rs854560 and C allele and CC variant of rs705379. The haplotype analysis has shown that the ATC haplotype was significantly more prevalent among the angiogram negative group. The analysis between groups indicated that the A allele of rs662 was significantly associated with lower paraoxonase activity in the positive angiogram group (p=0.019).The presence of the G allele of the rs662 single nucleotide polymorphism is independently associated to increased risk of CAD.Tem sido demonstrado que um aumento dos níveis séricos de PON1 é protetor contra vários distúrbios. Foi relatado que vários polimorfismos de nucleotídeo único (SNPs, single nucleotide polymorphisms ) do gene PON1 estão associados a níveis e atividade de proteínas enzimáticas séricas.Investigar a associação de SNPs do PON1 e atividade da paraoxonase sérica com a doença arterial coronariana (DAC).Foram estudados 601 pacientes não relacionados submetidos à angiografia coronária, incluindo aqueles com estenosegt;50% (N=266) e aqueles com estenoselt;30% (N=335). Os SNPs rs662 e rs840560 do gene da paraoxonase foram determinados utilizando o método ARMS-PCR e o SNP rs705379 foi genotipado utilizando análise de PCR-RFLP. A atividade da paraoxonase sérica foi medida utilizando paraoxon como substrato. O valor de plt;0,05 foi considerado significante.A atividade da paraoxonase sérica não foi significativamente diferente entre os grupos de estudo. Após ajuste para idade, sexo, hipertensão, diabetes mellitus e dislipidemia, o genótipo GG e o modelo codominante de rs662 foram positivamente associados a uma angiografia positiva (respectivamente, OR = 2,424, IC 95% [1,123-5,233], plt;0,05, OR = 1,663, IC 95% [1,086-2,547]). A atividade da paraoxonase sérica foi significativamente maior no alelo G e variante GG do polimorfismo rs662, alelo A e variante AA de rs854560 e alelo C e variante CC de rs705379. A análise de haplótipos mostrou que o haplótipo ATC foi significativamente mais prevalente no grupo com angiografia negativa. A análise entre os grupos indicou que o alelo A de rs662 foi significativamente associado à menor atividade da paraoxonase no grupo com angiografia positiva (p=0,019).A presença do alelo G do polimorfismo de nucleotídeo único rs662 está independentemente associada ao aumento do risco de DAC.

Background: Over the last decade, a few cases of visceral leishmaniasis (VL) have been reported in some provinces of northeastern Iran. We aimed to investigate clinical and laboratory findings of VL among children who admitted to the pediatric ward in a referral hospital in Mashhad, northeastern Iran. Methods: A retrospective study, between 1997 and 2017, was performed on the data sheet registered for children with confirmed VL at the referral Emam Reza Hospital in Mashhad. Hematological and biochemical profiles of the patients were analyzed. Results: Thirty-five children with VL, confirmed by the presence of amastigotes of Leishmania in Giemsa stained smears of the bone marrow, had been recorded through 20 yr. The mean age of patients was 3.7±4 yr. The majority of the patients suffered from hepatosplenomegaly (100%, n=35/35), followed by prolonged fever and pallor (91%, n=32/35), weight loss (85%, n=30/35). The main laboratory findings were anemia (94.1%), leukopenia (52.9%) and thrombocytopenia (70.5%). Almost one-third (37.1%; 13/35) of VL patients inhabited in rural areas of the Bojnoord district as a known VL endemic focus in northeastern Iran. Conclusion: Our preliminary data showed that the origin of VL is still in some districts other than Mashhad, where VL just will be diagnosed.

The relationship between physical activity levels (PAL) and the presence of cardiovascular disease (CVD) risk factors such as anthropometric and biochemical indices and heat shock proteins 27 antibody (anti-HSP-27) concentration, and serum inflammatory markers, was investigated in the MASHAD cohort study.The overall study population consisted of 9,684 subjects (3,858 men, 5,826 women) with a mean age of 47.73 ± 8.08 to 48.87 ± 9.26 years respectively. They were divided into four categories based on their PAL. Biochemical parameters were determined for all participants. Also, serum anti-HSP-27 levels were measured using an in-house enzyme-linked immune sorbent assay method. Multiple regression analysis was used to explore the association between the anti-HSP antibody titers and physical activity after adjusting for confounding factors. The level of statistical significance was set at p 0.05.Several CVD risk factors were associated with the level of PAL including: body mass index, waist hip ratio, systolic and diastolic blood pressure, serum HDL-C and TG (p 0.001) and also fasting blood glucose (0.004). Also, serum anti-HSP-27 titers were significantly higher in inactive subjects (P 0.05).We found that PAL was significantly associated with several established CVD risk factors. Also, the level of anti-HSP-27 was lower in individuals with moderate and high PAL.

Introduction: Cardiovascular disease (CVD) is the leading cause of mortality and one of the main challenges for health systems worldwide. In this study, we aimed to evaluate the role of socio-demographic, lifestyle, psychological factors, anthropometric measurements, and presence of underlying diseases in CVD progression among a subpopulation of Iranian adults. Methods A total of 235 CVD patients were enrolled. The control group also included healthy and non-symptomatic individuals (n = 8405). Health and lifestyle questionnaires, the Beck’s anxiety inventory (BAI), Beck’s depression inventory (BDI) and the James and Schofield human energy requirements equations were completed for all participants. Anthropometric measurements were also evaluated in all subjects. Results After six years of follow-up, we found that there were significant positive correlations between CVD risk and age, body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), diabetes mellitus (DM) and family history (FH) of CVD in both genders; though, there was a significant negative correlation between physical activity level (PAL) and risk of CVD among men and women. Also hypertension (HTN), metabolic syndrome (MS), depression and anxiety were positively and higher education level was negatively associated with CVD events only in females. While, waist-to-hip ratio (WHR) was an independent predictor of CVD among males. Conclusion There are several modifiable and non-modifiable risk factors that were independently considered as CVD predictors among the MASHAD study population. It is recommended that the lifestyle modifications, development of local risk calculators and gender-related stratified strategies should be prioritized in order to prevent and manage CVD among the Iranian population.

Background The role of dietary patterns in metabolic syndrome has not been investigated sufficiently among Iranian population. The aim of this study is to investigate the association of major dietary patterns with the risk of metabolic syndrome and its components among healthy individuals of Iran. Methods This is a cross-sectional study that was performed on 5895 men and women who participated in MASHAD study project. Factor analysis was employed to determine major dietary patterns with regard to a validated 65-item food frequency questionnaire. Metabolic syndrome was diagnosed using international diabetes federation (IDF). Logistic regression analysis was used to evaluate the association between dietary patterns and metabolic syndrome risk to generate odds ratios (ORs) and 95% confidence intervals (CI). Results Three major dietary patterns (Balanced, Western and high carbohydrate) were identified. The Western pattern showed a positive association with metabolic syndrome (OR [95%CI] for highest vs. lowest tertile: 1.58 [1.21–2.06]; p value = 0.001). The high carbohydrate dietary pattern was associated with higher metabolic syndrome risk (OR [95%CI] for highest vs. lowest tertile: 1.17 [1.02–1.33]; P value = 0.022). The Balanced dietary pattern was unrelated to metabolic syndrome, but was related to some individual risk factors for metabolic syndrome. Conclusions These results suggest that the Western and high carbohydrate patterns are associated with an increased risk for metabolic syndrome among Iranian adults. The causality of these associations needs to be confirmed.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality globally, and specifically in Iran. Generally, diabetes mellitus is the result of impaired glucose tolerance which together with dyslipidemia are considered as important risk factors of CVD. The aim of this study was to determine the relationship between fasting serum glucose (FSG), lipid profile and CVD endpoints, and to establish an optimal FSG cut-off in the MASHAD cohort study after nearly 6 years of follow-up. METHODS: All the participants of MASHAD study were followed up for 6 years to determine their cardiovascular status. FSG, fasting lipids, and physical examinations were all recorded. To identify the optimal cut- off point of FSG, we carried out receiver operating curve (ROC) analysis RESULTS: We determined MASHAD cutoff point of blood glucose as 90 mg/dl predicting the CVD outcome. The sensitivity and specificity of the FSG criterion were 54.34% and 71.68%, respectively. The AUC was 0.665 (95% CI 0.656-0.675, P< 0.0001). The adjusted hazard ratio show that FSG is associated with 2.34 increase in CVD risk using MASHAD cutoff point (HR 2.34, 95% 1.73–3.17, P< 0.001). CONCLUSION: These findings suggest that not only FSG and lipid profile are related to CVD outcome in the MASHAD study, but also elevated fasting glucose levels is strongly associated with cardiovascular events in this population. Besides, the fasting glucose at a threshold of 90 mg/dl can be used for screening cardiovascular events among the Iranian population.

Summary Background & aims Several genome-wide-association-studies have identified genetic variants in a region on chromosome 9p21 that are associated with an increased risk of Cardiovascular disease (CVD) and diabetes. Here we have explored the interaction of a genetic variant of the CDKN2A/B-rs10811661 gene locus with cardiovascular risk factors and environmental-exposures (e.g., diet and physical activity) in 1165 individuals recruited from the Mashhad-Stroke and Heart-Atherosclerotic-Disorders cohort. Methods Genotyping was carried out using TaqMan-real-time-PCR based method. The association of CDKN2A/B-rs10811661 locus and its interaction with dietary intake in association with the main determinants of dyslipidemia, and cardiovascular-risk-factors were assessed in 2 cohorts. Results Our data showed that obese subjects with a TT genotype had a higher level of TG, TG/HDL ratio and Hs-CRP, compared to the subjects with the wild type genotype, or individuals with a normal BMI. Moreover, the presence of a TT genotype was associated with increased risk of hypercholesterolemia, insulin resistance and CVD. These effects were more pronounced in the sub-group with low physical activity and a high dietary energy intake (e.g., the interaction between TT genotype and total energy intake on serum cholesterol was positive (RERI: 0.2, 95%CI (−0.96–1.3), AP: 0.1, 95%CI (−0.5–0.7) and SI: 1.2, 95%CI (0.3–5.1))). Conclusions We have found a significant association between the CDKN2A-rs10811661 polymorphism with cardiovascular risk factors and dyslipidemia in a non-diabetic population. It is possible that a low energy diet and high physical activity could ameliorate the unfavorable effects of T allele of CDKN2A/B locus. Functional analysis is warranted to investigate the value of this genetic biomarker of CVD risk in obese people.

Metabolically obese normal weight (MONW) individuals are potentially at increased risk of developing metabolic syndrome. Serum zinc and copper concentrations were assessed in individuals with MONW to determine whether MONW is associated with altered serum zinc and/or copper status. Normal weight subjects (total n = 2419; 1298 men and 1121 women), were recruited as part of Mashhad Stroke and Heart Association Disorder (MASHAD) Study cohort. They were divided into two groups according to the presence or absence of MetS, defined using IDF criteria. Serum zinc and copper concentrations were determined by atomic absorption. Of the 2419 normal weight adults, 377 had MetS. Of this group, 53.7% and 49.7% had a serum zinc 131 µg/dl (Q4) (p = 0.034), and 18.8% had a serum zinc >95 µg/dl (Q4). Logistic regression analysis was performed to determine the odds ratio (OR) for an association of serum zinc, copper and zinc to copper ratio with MetS in normal weight subjects. The subjects with a serum zinc >95 µg/dl (Q4) had 0.386 [OR: 0.614(95%CI 0.457–0.823)] lower chance of MetS (p = 0.001) and the subjects with a serum copper >131 (Q4) had OR 1.423 (95% CI: 1.09–1.857) higher chance of MetS (p = 0.009). These data remained significant after adjustment for age and sex, for serum zinc and copper, respectively. Furthermore, our results strongly suggested that zinc and copper were the independent risk factor for metabolic syndrome in normal weight subjects. There is an imbalance between serum copper and zinc concentrations among individuals with MONW when compared with normal BMI individuals without MetS. This may increase the risk of individuals with MONW developing conditions associated with this imbalance, such as diabetes and cardiovascular disease.

Several chronic diseases are mediated by oxidative stress. Oxidative stress affects cell morphology and function and is associated with alterations in the serum protein component. In the current study, we analyzed four individual prognostic factors associating with serum Pro-Oxidant-Antioxidant Balance (PAB): neutrophil to lymphocyte ratio (NLR), Vitamin D, anti-heat shock protein 27 (anti-hsp27) antibody titer, and red blood cell distribution width (RDW) to evaluate them as the potential prognostic markers. In the current study, we attempted to investigate the relationship between serum PAB, RDW, NLR, serum vitamin D and anti-hsp27 concentration.A total of 852 participants (438 males and 414 females) aged 47.64 ± 7.77 years were recruited in a cross-sectional study based on the Mashhad stroke and heart atherosclerotic disorders (MASHAD) cohort study data. Hematological parameters, and vitamin D, PAB and anti-hsp27 antibody titers were measured using the Sysmex auto analyzer system and enzyme-linked immune sorbent assay (ELISA), respectively.The results showed a significant correlation between Vitamin D and anti-hsp27 antibody titers (r = -0.13 and p0.001) as well as between RDW and serum PAB (r = 0.120 and p0.001). Moreover, we found that serum PAB was positively associated with serum anti hsp27 antibody titers. The results showed increasing 1 unit of serum vitamin D can cause 3% decreases in anti hsp 27 values (OR = 0.97; CI 95% (0.96-0.99); p = 0.004). While this association was not significant for RDW, NLR and PAB (p0.05) we found a significant association between serum PAB and serum anti hsp-27 antibody titers. Subjects with PAB levels 36.31-82.63 had a higher risk (1.83 fold) of having an increased anti-hsp27 antibody titers in comparison to the reference group (PAB level36.31) (OR = 1.83 (95% CI = 1.33-2.52), p0.001).The present study shows that serum vitamin D can be associated with reduction in inflammatory status probably by decreasing levels of serum anti-hsp27 antibody titers, reduction in oxidative stress and therefore may reduce the risk of cardiovascular diseases. Anti-hsp27 antibody titers are associated with oxidative stress through the serum PAB, therefore these factors may be of prognostic values in detecting oxidative stress and risk of atherosclerosis. The evaluation of these factors in a larger population may help further confirm these findings.

Background and Purpose: Detection of agents responsible for cutaneous mycosis may be effective in the prevention of fungal infections from environmental and animal sources. With this background in mind, in this study, we aimed to identify the distribution of cutaneous mycotic infections in patients referred to Imam Reza Hospital of Mashhad, Iran during 2000- 2011. Materials and Methods: In total, 8694 patients suspected of superficial and cutaneous mycosis, referred to the Medical Mycology Laboratory of Imam Reza Hospital of Mashhad, Iran, were recruited during March 2000-2011 and were examined in terms of fungal infections. Results: Of 8694 suspected patients, 3804 (43.75%) cases suffered from superficial and cutaneous mycosis. In total, 1936 (50.9%) patients were male, and 1868 (49.1%) were female. Malassezia infections (58.1%), dermatophytosis (33.1%), cutaneous candidiasis (6.8%), aspergillosis (1.6%), and saprophytic cutaneous mycosis (0.4%) were the most common infections. Conclusion: In this study, Malassezia infections were the most common superficial and cutaneous mycoses. Therefore, it seems essential to focus on the prevention of these infections in our society.

Metabolic syndrome (MetS) is a risk factor for type 2 diabetes mellitus and cardiovascular disease. Obesity is a component of the metabolic syndrome. Several genetic variants are reported to be associated with obesity and hypo adiponectinemia, including ars1800796 polymorphism of the interleukin-6 (IL-6) gene. Since obesity is associated with inflammatory factors, the aim of this study was to investigate the association between this polymorphism and MetS and its related features. Obese patients with body mass index (BMI) ≥ 30 (n = 182) were recruited into this study and divided into two groups; 110 patients with MetS, based on the International Diabetes Federation (IDF) criteria, and 72 subjects without MetS. The anthropometric and biochemical data for the groups were compared. Genotyping was carried out using RT-PCR. The association of the genetic polymorphism with MetS and its components were assessed using univariate and multivariate analyzes. There was an association between the presence of the rs1800796polymorphism of the IL-6 gene, with BMI (P = 0.031), high-density lipoprotein (HDL) (P = 0.010) and low-density lipoprotein (LDL) (P = 0.037), while this genetic variant did not show any significant association with the presence of MetS as defined by the IDF. We demonstrate an association between the rs1800796 genetic variant of the IL-6 gene with components of MetS including BMI, and HDL-cholesterol, but not the MetS itself. Therefore, supporting further studies are warranted to investigate this point in a larger population.
