No Evidence of Hepatitis C Virus Infection in Individuals with Cardiovascular Disease in Mashhad
Background and Aim: Hepatitis C virus (HCV) infection is one of the leading causes of morbidity and mortality worldwide. It has been hypothesized that a number of bacteria and viruses might be involved in the pathogenesis of cardiovascular disease. The aim of this study was to define the prevalence of HCV in patients with cardiovascular disease in comparison with a control group.
Methods: In this study, 281 individuals including 143 cardiovascular patients and 138 healthy controls were assessed for identification of HCV antibodies. The data collection was done between April 2016 and February 2017. The prevalence of HCV antibodies was determined by the enzyme-linked immunosorbent assay (ELISA) method.
Results: There was no HCV infection in both patients with or without cardiovascular disease. There was a significant direct correlation between cardiovascular diseases and mean level of FPG (Fasting plasma glucose) (p<0.001). Also the Systolic and Diastolic blood pressures were significantly higher in the patients with cardiovascular disease (p<0.001 and p=0.005, respectively).
Conclusion: The results of this study show that no evidence of HCV infection is found among a group of cardiovascular patients in the city of Mashhad.

Depression and anxiety symptoms are associated with prooxidant-antioxidant balance: a population-based study
Background: Depression and anxiety are significantly associated with systemic inflammation. Moreover, oxidative stress resulting from a disturbance in the prooxidant-antioxidant balance is linked to inflammation-related conditions. Therefore, depression/anxiety symptoms may also be associated with oxidative stress.
Objective: To examine the association between depression/anxiety symptoms and serum prooxidant-antioxidant balance (PAB) in adults who participated in a large population-based, cross-sectional study.
Methods: Serum PAB values were measured in 7,516 participants (62% females and 38% males) aged 35–65 years, enrolled in a population-based cohort study. Beck Depression and Anxiety Inventories were used to evaluate symptoms of depression and anxiety. Multinomial logistic regression was used to examine the effect of confounders on the status of serum PAB change.
Results: Among men, serum PAB values were increased incrementally from 1.55±0.47 to 1.59±0.47, 1.69±0.38, and 1.68±0.38 in the no or minimal, mild, moderate and severe depression groups, respectively (P trend<0.001). Serum PAB values also increased significantly across these four corresponding groups among women [1.70±0.45, 1.73±0.44, 1.75±0.44, and 1.76±0.40, (P trend=0.005)]. About anxiety, serum PAB values increased significantly across the four groups in men (P trend=0.02) but not in women (P trend=0.2). The adjusted odds ratios for serum PAB values among men with severe depression and anxiety symptoms were 1.75 and 1.27, respectively. Moreover, the adjusted odds ratios for serum PAB values among women with severe depression and anxiety symptoms were 1.40 and 1.17, respectively.
Conclusion: Symptoms of depression and anxiety appear to be associated with higher degrees of oxidative stress, expressed by higher serum PAB values
A novel splice site variant in the LDLRAP1 gene causes familial hypercholesterolemia
Background: familial hypercholesterolemia (FH), a hereditary disorder, is caused by pathogenic variants in the LDLR, APOB, and PCSK9 genes. This study has assessed genetic variants in a family, clinically diagnosed with FH.
Methods: A family was recruited from MASHAD study in Iran with possible FH based on the Simon Broom criteria. The DNA sample of an affected individual (proband) was analyzed using whole exome sequencing, followed by bioinformatics and segregation analyses.
Results: A novel splice site variant (c.345-2A>G) was detected in the LDLRAP1 gene, which was segregated in all affected family members. Moreover, HMGCR rs3846662 g.23092A>G was found to be homozygous (G/G) in the proband, probably leading to reduced response to simvastatin and pravastatin.
Conclusion: LDLRAP1 c.345-2A>G could alter the phosphotyrosine-binding domain, which acts as an important part of biological pathways related to lipid metabolism

The prevalence of metabolic syndrome increases with serum hs-CRP concentration in individuals without a history of cardiovascular disease: a report from a large Persian cohort
BACKGROUND:
Metabolic syndrome (MetS) is defined by a clustering of cardiovascular (CV) risk factors and is associated with a heightened inflammatory state. A raised serum high-sensitivity C-reactive protein (hs-CRP), a marker of inflammation, is also known to associate with CV risk. We have investigated the relationship between the presence of MetS and serum hs-CRP concentration in a large representative Persian population cohort without a history of cardiovascular disease (CVD).
METHODS:
The MASHAD study population cohort comprised 9 778 subjects, who were recruited from the city of Mashhad, Iran, between 2007 and 2008. Several cardiovascular risk factors were measured in this population without CVD. Individuals were categorized into quartiles of serum hs-CRP concentration: 1st quartile - 0.72 (0.59-0.85) [median (range)] mg/L, 2nd quartile - 1.30 (1.14-1.4) mg/L, 3rd quartile - 2.29 (1.92-2.81) mg/L and 4th quartile - 6.63 (4.61-11.95) mg/L respectively. The prevalence of MetS in each quartile was determined using either International Diabetes Federation (IDF) or Adult Treatment Panel III (ATPIII) criteria.
RESULTS:
The prevalence of MetS was highest in the 4th quartile for serum hs-CRP [1220 subjects (50.0%)], and significantly higher than that in the 1st quartile (reference group) [634 subjects (25.9%)] (p<0.001). A positive smoking habit [OR, 1.47 (1.26-1.70), p<0.001] and the presence of either MetS-IDF [OR, 1.35 (1.18-1.55), p<0.001] or Mets-ATPIII [OR, 1.40 (1.18-1.50), p<0.001] were strong predictors of a 4th quartile for serum hs-CRP concentration.
CONCLUSIONS:
There was a significant association between high levels of serum hs-CRP and the presence of MetS among individuals without a history of CVD in our Persian cohort

The interaction between a HSP-70 gene variant with dietary calories in determining serum markers of inflammation and cardiovascular risk
Background: The high prevalence of cardiovascular disease (CVD) globally is attributable to an interaction between environmental and genetic factors. Gene × diet interaction studies aim to explore how a modifiable factor interacts with genetic predispositions. Here we have explored the interaction of a heat shock protein (HSP70) gene polymorphism (+1267A>G) with dietary intake and their possible association with serum C-reactive protein (CRP), an inflammatory marker, that is a major component of CVD risk.
Methods: HSP70 genotype was determined using a TaqMan real time PCR based method. Genetic variation of the HSP70 gene +1267A>G locus. Dietary intake was assessed using a dietary questionnaire. Serum high sensitivity (Hs) CRP and other cardiovascular risk factors were assessed by routine methods. This included coronary angioplasty to determine the presence of coronary artery stenosis.
Results: There were significant differences between serum lipid profile and Hs-CRP across the genotypes for Hsp70. The carriers of G allele had higher serum hs-CRP concentrations, compared with the AA homozygotes, with the wild genotype. Interaction analysis showed the association was modulated by total energy intake; the interaction of high energy intake with GG genotype: RERI= 0.77, AP= 0.26, S=1.6.
Conclusion: We have found a significant association between the +1267A>G variant of the HSP70 gene with cardiovascular risk factors and serum hs-CRP concentrations. It is possible that a low energy diet could ameliorate the unfavorable effects of G allele of HSP70
Relationship between platelet count and platelet width distribution and serum uric acid 1 concentrations in patients with untreated essential hypertension
Hematological parameters have emerged as independent determinants of high serum concentrations of uric-acid and predictive-factors in the evaluation of the total cardiovascular-risk in patients with essential-hypertensive. Here we have investigated the possible relationships between hematological-factors and serum uric-acid levels in hypertensive-patients recruited as part of Mashhad-Stroke and Heart-Atherosclerotic-Disorders cohort study. Two-thousand three-hundred and thirty four hypertensive individuals were recruited from this cohort and these were divided into two groups; those with either high or low serum uric acid concentrations. Demographic, biochemical and hematological characteristics of population were evaluated in all the subjects. Logistic-regression-analysis was performed to determine the association of hematological-parameters with hypertension. Of the 2334 hypertensive-subjects, 290 cases had low uric-acid, and 2044 had high serum uric acid concentrations. Compared with the low uric acid group, the patients with high serum uric acid, had higher values for several hematological parameters, whilst platelet counts (PLT) were lower. Multiple linear regression analysis showed that PLT and serum hs-CRP were correlated with serum uric acid level. Stepwise multiple logistic regression model confirmed that PDW and gender were independent determinant of a high serum uric acid. PDW and PLT appear to be independently associated with serum uric acid level in patients with hypertension
Association between obesity categories with cardiovascular disease and its related risk factors in the MASHAD cohort study population
Background
Cardiovascular disease (CVD) is a significant cause of morbidity and mortality globally. Obesity is an important CVD risk factor and is increasing in prevalence.
Methods
In this study, 3829 men and 5720 women (35‐65 years) were enrolled as part of the MASHAD cohort study. Four categories were identified according to body mass index and waist circumference that was defined by the World Health Organization. Logistic regression analysis was used to determine the adjusted odds ratio (OR) for the occurrence of CVD, and Cox regression model was used to evaluate the association of obesity with CVD incidence.
Results
We found that the higher risk groups defined by categories of adiposity were significantly related to a higher prevalence of a high serum total cholesterol (TC), and triglycerides (TG), and lower high‐density lipoprotein cholesterol (HDL), and higher fasting blood glucose (FBG) in both genders and a higher low‐density lipoprotein cholesterol (LDL) in women (P < .001). Additionally, a high percentage of participants with dyslipidemia, high LDL, high TC, and low HDL and a high percentage of participants with metabolic syndrome, diabetes, hypertension, and a high serum TG were observed across obesity categories (P < .001). Moreover, women with the very high degrees of obesity had a greater risk of CVD (HR: 1.91, 95% CI: 1.06‐3.43, P = .03).
Conclusion
Obesity strongly predicts several CVD risk factors. Following 6 years of follow‐up, in individuals within increasing degrees of obesity, there was a corresponding significant increase in CVD events, rising to approximately a twofold higher risk of cardiovascular events in women compared with men
Overweight and obesity are potential risk factors for disrupted nocturnal sleep in Iranian adults: a cross-sectional study
Objectives: Obesity is a risk factor for several chronic conditions, including sleep disorders. We aimed to analyze the relationship between BMI, body fat percentage (FAT%), hip and waist circumference, and weight on the duration of nocturnal sleep.
Methods: This study was part of the MASHAD cohort study. In all participants BMI and FAT% were measured. BMI was used to categorize individuals as obese, overweight, and normal subjects. FAT% was used to categorize individuals into tertile: tertile 1 (low) 41. The level of nightly sleep duration was categorized into three groups: 8 h.
Results: There was a significant inverse association between body weight and duration of sleep (p < 0.05). Obese and overweight participants had 1.152 OR (CI:1.083–1.225) and 1.126 OR (CI:1.063–1.194) for a short duration of nocturnal sleep, respectively, relative to those with a normal BMI.
Conclusion: BMI was an independent determinant of nocturnal sleep duration; obesity and overweight may have negative consequences on sleep duration. Weight control should be considered as a factor in adjusting sleep quality
A genetic variant in proline and serine rich coiled-coil 1 gene is associated with the risk of cardiovascular disease
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.
Conclusions:
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
Factors Associated with The Incidence of Coronary Heart Disease in The Mashad: A Cohort Study
Coronary heart disease (CHD) is the leading cause of morbidity and mortality globally, and specifically in Iran. Accurate assessments of Coronary heart disease (CHD) incidence is very necessary 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 of follow-up. Methods The population of MASHAD cohort study were followed up for 6 years, every 3 years in two step by phone and who reported symptoms of CVD were asked to attend for a cardiac examination, to estimate the incidence of CHD with 95% confidence interval (95% CI) as well multiple logistic regression analysis was performed to assess the association of several baseline characteristics with incidence of CHD event. Evaluation of goodness-of-fit was done using ROC analysis. CHD cases divided into four different classes which include: stable angina, unstable angina pectoris, myocardial infarction and sudden cardiac death. Results In the six years\u27 follow-up of Mashhad study, the incidence rate of all CHD event in men and women in 100,000 people-years with 95% confidence intervals were 1920 (810-3030) and 1160 (730-1590), respectively. The areas under ROC curve (AUC), based on multivariate predictors of CHD outcome, was 0.7825. Conclusion Our findings indicated that the incidence rate of coronary heart diseases in MASHAD cohort study increases with age as well as our final model designed, was able to predict approximately 78% of CHD events in Iranian population
