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.

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 association of socio-demographic, lifestyle, psychological and anthropometric factors and underlying diseases such as hypertension (HTN), diabetes mellitus (DM) and metabolic syndrome (MS) with CVD risk among a subpopulation of Iranian adults. Methods: In this prospective study, a total of 235 CVD patients along with 8405 healthy and nonsymptomatic individuals who participated in MASHAD cohort study were enrolled. CVD diagnosis was performed by taking electrocardiogram (ECG) and medical history and performing physical examination for each participant. 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 recorded for all subjects. All statistical analyses including chi-square and student independent T-test were performed using SPSS 16.0 software (SPSS Inc., Chicago, IL, USA) at a significant level of 0.05. Results: We found that there were significant associations 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 (P-value< 0.05). Conclusion: There are several modifiable and non-modifiable risk factors that are independently considered as CVD predictors among the MASHAD study population. It is recommended to prioritize the lifestyle modification, development of local risk calculators and gender-related stratified strategies in order to prevent and manage CVD among the Iranian population.

Introduction: The association between the serum antibody titer of several heat shock proteins (HSPs) and cardiovascular disease (CVD) risk factors so far has been the subject of several previous studies. Aim: To evaluate the association of adiposity indices and HSP-27 antibody titers in healthy individuals. Materials and Methods: Overall 4823 individuals were recruited from Mashhad Stroke and Heart Atherosclerotic Disorders Study (MASHAD study), that included 1496 individuals with normal-weight (body mass index (BMI) <25 kg/m2), 1975 individuals with over-weight (BMI 25-30 kg/m2), and 1352 individuals with obesity (BMI≥ 30 kg/m2). Results: The serum anti-HSP-27 antibody titers were not significantly different among obese individuals [0.21 (0.11 - 0.34) absorbency unit (AU)], over-weight individuals [0.19 (0.10 - 0.33) AU] and normal-weight individuals [0.19 (0.10 - 0.33) AU]. Conclusions: we have found no significant relationship among anti-HSP-27 antibody concentration and degrees of adiposity among Iranian adults. [ABSTRACT FROM AUTHOR]

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.

Hypertriglyceridemia is a common form of dyslipidemia and is associated with several comorbidities, such as increased risk of pancreatitis and cardiovascular diseases (CVD). The white blood cell (WBC) count is a non-specific inflammatory marker associated with a wide variety of diseases such as diabetes, hypertension, and atherosclerotic cardiovascular disease. The objective of this study was to perform a genderstratified examination of the association between hypertriglyceridemia and hematological parameters in a large sample of Iranian population. The triglyceride (TG) levels and hematological parameters were measured in 9,780 participants (40% males and 60% females) aged 35-65 years, enrolled in a population-based cohort (MASHAD) study in northeastern Iran. Participants were stratified into three groups based on the definition of hypertriglyceridemia: TG<150 mg/dl (n=6521), TG=150-199 mg/dl (n=1597), and TG≥200 mg/dl (n=1662). A complete blood count (CBC) was obtained for all the subjects. The mean WBC count increased with increasing severity of hypertriglyceridemia among both men and women. Participants with high and very high TG levels had significantly higher WBC count, RBC count, platelet count, hemoglobin, hematocrit, and mean corpuscular hemoglobin concentration and significantly lower RDW. After performing multivariate logistic regression, WBC count and RDW were independently related to hypertriglyceridemia. In conclusion, hypertriglyceridemia is associated with elevated WBC count which may partly explain the observed association between hypertriglyceridemia and CVD. [ABSTRACT FROM AUTHOR]

Background: Heart failure (HF) is becoming one of the important health care problems around the world. Physical activity as the foundation of the cardiac rehabilitation program is poorly adhered by patients with HF. This study aimed to understand the experiences of patients with HF in terms of adherence to physical activity., Materials and Methods: This study was conducted using conventional qualitative content analysis. Data were collected by semistructured telephone interviews with 25 patients with HF through open-ended questions. Data were collected from patients with HF in Birjand and Mashhad hospitals and heart departments from December 2021 to March 2022. Data were analyzed using Max-QDA10 and data analysis was continuous, comparative, and simultaneous with data collection., Results: After data analysis, three main categories were identified: (1) patient-related barriers and facilitators, (2) support system-related barriers and facilitators, and (3) environmental barriers and facilitators. These categories were subdivided into two main themes: (1) threatening disease and (2) challenging disease., Conclusion: The results showed that beyond patient-related, support system-related, and environmental categories, perceiving the disease as a challenge or a threat is crucial in the activity of patients with HF. Nurses and other health care providers can train problem-solving behaviors to patients with HF to improve their physical and mental well-being. It is suggested that theoretical-behavioral approaches can be used in future clinical trials to improve adherence to physical activity., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Journal of Education and Health Promotion.)

Background: Metabolic syndrome (MetS) is a cluster of clinical and metabolic features that include central obesity, dyslipidemia, hypertension and impaired glucose tolerance. These features are accompanied by increased oxidative stress and impaired antioxidant defenses. Vitamin E is a major factor in the non-enzymatic antioxidant defenses. The aim of present study was to investigate the association between serum levels of vitamin E and the presence of MetS and its components in a sample population of Mashhad stroke and heart atherosclerotic disorder (MASHAD) cohort study., Methods: This cross-sectional study was carried out in 128 subjects with MetS and 235 subjects without MetS. MetS was defined according to the International-Diabetes-Federation criteria. Serum levels of vitamin E were measured using the HPLC method. Anthropometric and biochemical parameters were measured using standard protocols.  Results. MetS patients had significantly lower serum levels of vitamin E (Vit E), Vit E/Total cholesterol (TC), and Vit E/ (TC+triglyceride(TG)) compared to the control group (P < 0.05).  Vit E/ (TG+TC) was also significantly lower in diabetics or those with elevated levels of high sensitive C-reactive protein (hs-CRP). Additionally, there was a significant association between Vit E/ (TG + Total Cho) and the number of components of the metabolic syndrome (p= 0.02) Conclusions. There is a significant inverse association between indices of Vit E status and the presence of MetS. Moreover, a significantly lower Vit E/ (TC+TG) was observed along with individuals with increasing numbers of components of the MetS.

Introduction: Fingolimod is the first confirmed oral immune-modulator to treat Relapsing-Remitting Multiple Sclerosis (RRMS). This study aimed to investigate the safety and efficacy of fingolimod therapy in Iranian patients with RRMS., Methods: In our trial, 50 patients resistant to conventional interferon therapy were assigned to receive fingolimod 0.5 mg per day for 12 months. The number of Dadolinium (Gd)-enhanced lesions, enlarged T2 lesions, and relapses over 12 months were considered as endpoints and compared to baseline. Liver biochemical evaluations and lymphocyte count were done at baseline and in months 3, 6, and 12 of the study. Patients were also monitored for possible cardiovascular events within the first 24 h and other side effects routinely., Results: Among the patients who completed the trial, the number of Gd-enhanced and enlarged T2 lesions over 12 months significantly decreased (P=0.03 and P<0.001, respectively). The proportion of relapse-free patients was higher compared to the onset of fingolimod administration. There were no significant alterations in the Expanded Disability Status Scale (EDSS) scores. A slight, transient increase was recorded in liver enzymes among the participants. Lymphocyte count reduced by 61% at month 1 and displayed a gradual increase until month 12. No bradycardia and macular edema were recorded., Conclusion: These findings indicate an effective first-line fingolimod therapy for the first time in Iranian patients with RRMS. The decrease in the number of new attacks and the amelioration of MRI lesions were the benefits of fingolimod therapy, suggesting that it is preferred to other medicines to treat RRMS in Iran., Competing Interests: Conflict of interest The authors declared no conflict of interest., (Copyright© 2021 Iranian Neuroscience Society.)
