RESUMEN
BACKGROUND: Acute coronary syndrome is a significant global health concern that can affect patients' health outcomes and quality of life. In addition, adherence to treatment and health literacy can affect health outcomes. OBJECTIVE: This study aimed to investigate the relationship between treatment adherence, health literacy, and quality of life among patients with acute coronary syndrome. METHODS: This cross-sectional study was conducted on 407 patients in Iran from April 2019 to November 2019. Patients were selected by convenience sampling method. Data were collected using demographic questionnaire, World Health Organization Quality of Life Brief Version, Adherence to Treatment Questionnaire, and Health Literacy for Iranian Adults questionnaire. SPSS 25 was used for statistical analysis. RESULTS: Based on descriptive statistics in this study, most of the participants had good treatment adherence level (56.5%); 28.7% of the participants had insufficient health literacy level. The mean score of quality of life was 51.41 ± 12.03, which was greater than the midpoint of the questionnaire. Furthermore, Pearson's correlation coefficient showed a negative association between health literacy, treatment adherence (r = -0.167, p < .01), and quality of life (r = -0.153, p < .01), and a positive association between treatment adherence and quality of life (r = 0.169, p < .01). CONCLUSION: The results of the current study showed a negative relationship between health literacy, quality of life, and treatment adherence among patients with acute coronary syndrome.

Cardiovascular disease (CVD) is the leading cause of death and disability in people with diabetes mellitus (DM), since finding the correlation between DM and CVD risk factors can be effective in preventing the incidence of morbidity and mortality in patients. This study aimed to determine the prevalence of cardiovascular risk factors in people with and without metabolic syndrome (MtS) in DM. This cross-sectional study was part of the Rafsanjan Cohort Study as part of the comprehensive Persian (Prospective Epidemiological Research Studies in IRAN) on 35-70-year old adults with and without MtS in DM. Indicators of CVD risk factors, including gender, age, blood pressure, dyslipidemia, smoking, alcohol consumption, fasting blood sugar, creatinine, blood urea, waist circumference, body mass index, family history, physical inactivity, and fruit and vegetable consumption, were collected in the Persian Cohort Questionnaire. The data was analyzed by SPSS software version 22. The prevalence of MtS in 1933 participants was estimated to be 80% (95% confidence interval 78.1-81.8%). In the logistic regression model, smoking, alcohol consumption, and triglycerides were identified as the factors associated with MtS. Our results show that, based on our study, the prevalence of cardiovascular risk factors in DM was high. The suggested solutions in this field are to reduce smoking and alcohol consumption, as well as to control hypertension, hyperlipidemia, and being overweight.

BACKGROUND: Elevated blood pressure is associated with cardiovascular disease, stroke and chronic kidney disease. In this study, we examined the socioeconomic inequality and its related factors in prevalence, Awareness, Treatment and Control (ATC) of hypertension (HTN) in Iran. METHOD: The study used data from the recruitment phase of The Prospective Epidemiological Research Studies in IrAN (PERSIAN). A sample of 162,842 adults aged > = 35 years was analyzed. HTN was defined according to the Joint National Committee)JNC-7(. socioeconomic inequality was measured using concentration index (Cn) and curve. RESULTS: The mean age of participants was 49.38(SD = ± 9.14) years and 44.74% of the them were men. The prevalence of HTN in the total population was 22.3%(95% CI: 20.6%; 24.1%), and 18.8%(95% CI: 16.8%; 20.9%) and 25.2%(95% CI: 24.2%; 27.7%) in men and women, respectively. The percentage of awareness treatment and control among individuals with HTN were 77.5%(95% CI: 73.3%; 81.8%), 82.2%(95% CI: 70.2%; 81.6%) and 75.9%(95% CI: 70.2%; 81.6%), respectively. The Cn for prevalence of HTN was -0.084. Two factors, age (58.46%) and wealth (32.40%), contributed most to the socioeconomic inequality in the prevalence of HTN. CONCLUSION: The prevalence of HTN was higher among low-SES individuals, who also showed higher levels of awareness. However, treatment and control of HTN were more concentrated among those who had higher levels of SES, indicating that people at a higher risk of adverse event related to HTN (the low SES individuals) are not benefiting from the advantage of treatment and control of HTN. Such a gap between diagnosis (prevalence) and control (treatment and control) of HTN needs to be addressed by public health policymakers.

Coronary artery disease (CAD) and coronary heart disease (CHD) constitute two of the leading causes of death in Europe, USA and the rest of the world. According to the latest reports of the Iranian National Health Ministry, CAD is the main cause of death in Iranian patients with an age over 35 years despite a significant reduction in mortality due to early interventional treatments in the context of an acute coronary syndrome (ACS). Inflammation plays a fundamental role in coronary atherogenesis, atherosclerotic plaque formation, acute coronary thrombosis and CAD establishment. Chemokines are well-recognized mediators of inflammation involved in several bio-functions such as leucocyte migration in response to inflammatory signals and oxidative vascular injury. Different chemokines serve as chemo-attractants for a wide variety of cell types including immune cells. CXC motif chemokine ligand 10 (CXCL10), also known as interferon gamma-induced protein 10 (IP-10/CXLC10), is a chemokine with inflammatory features whereas CXC chemokine receptor 3 (CXCR3) serves as a shared receptor for CXCL9, 10 and 11. These chemokines mediate immune responses through the activation and recruitment of leukocytes, eosinophils, monocytes and natural killer (NK) cells. CXCL10, interleukin (IL-15) and interferon (IFN-g) are increased after a COVID-19 vaccination with a BNT162b2 mRNA (Pfizer/BioNTech) vaccine and are enriched by tumor necrosis factor alpha (TNF-α) and IL-6 after the second vaccination. The aim of the present study is the presentation of the elucidation of the crucial role of CXCL10 in the patho-physiology and pathogenesis of CAD and in identifying markers associated with the vaccination resulting in antibody development.
RESUMEN
BACKGROUND: Self-reported substance use is more likely to be influenced by underreporting bias compared to the biological markers. Underreporting bias or validity of self-reported substance use depends on the study population and cannot be generalized to the entire population. This study aimed to compare the validity of self-reported substance use between research setting and primary health care setting from the same source population. METHODS AND MATERIALS: The population in this study included from Rafsanjan Youth Cohort Study (RYCS) and from primary care health centers. The sample from RYCS is made up 607 participants, 113 (18.62%) women and 494 (81.38%) men and sample from PHC centers is made up 522 individuals including 252 (48.28%) women and 270 (51.72%) men. We compared two groups in respect of prevalence estimates based on self-reported substance use and urine test. Then for evaluating validity of self-reported substance use in both group, the results of reference standard, urine tests, were compared with the results of self-reported drug use using measures of concordance. RESULTS: The prevalence of substance use based on urine test was significantly higher in both settings compared to self-reported substance use over the past 72 h. The sensitivity of self-report substance use over the past 72 h in research setting was 39.4, 20, 10% and zero for opium, methadone, cannabis and amphetamine, respectively and in primary health care setting was 50, 20.7, 12.5% and zero for opium, methadone, cannabis and amphetamine, respectively. The level of agreement between self-reported substance use over the past 72 h and urine test indicated fair and moderate agreement for opium in both research and primary health care settings, respectively and also slight agreement for methadone and cannabis in both settings were reported. There was no significant difference between the two groups in terms of self-reported substance use. For all substances, the level of agreement increased with longer recall periods. The specificity of self-report for all substances in both groups was more than 99%. CONCLUSION: Individuals in primary health care setting were more likely to self-reported substance use than in research setting, but setting did not have a statistically significant effect in terms of self-reported substance use. Programs that rely on self-reported substance use may not estimate the exact prevalence of substance use in both research and primary health care settings, especially for substances that have a higher social stigma. Therefore, it is recommended that self-report and biological indicators be used for more accurate evaluation in substance use studies. It is also suggested that future epidemiological studies be performed to reduce bias of social desirability and find a method providing the highest level of privacy.

INTRODUCTION: The family members' presence during teaching rounds is introduced as a challenging issue. The outcomes of family presence during teaching rounds in adult care settings is an under investigate issue. The propose of this study was to determining the effect of family presence at teaching rounds on patient's anxiety and satisfaction in cardiac intensive care unit (CICU). MATERIALS AND METHODS: In this double-blind randomized controlled trial, 60 patients who were hospitalized in CICU were selected based on inclusion criteria and then assigned into 2 groups (with and without family members presence during teaching round), equally by the random minimization method. The patient's anxiety score was measured before and after rounds on the Spielberger State-Trait Anxiety Inventory (STAI). Furthermore, the patient's satisfaction about various clinical aspects of round was measured by a self-reported questionnaire. The data were analyzed by SPSS software using Kolmogorov-Smirnov test, Chi-square test, independent sample and paired sample t-test, at the significance level of 0.05. RESULTS: The study groups were similar in terms of demographic variables. In the family members presence group, the STAI score significantly decreased after intervention (P = 0.001). Furthermore, in this group, the after-intervention STAI score was significantly lower than family absence group (P = 0.011). The mean changes of patient's satisfaction about quality of round score in family member presence group were significantly higher than family absence group (P = 0.001). CONCLUSIONS: Family presence during teaching rounds led to patient's lower anxiety and higher satisfaction score.
RESUMEN
Arrhythmia means the heart is beating too fast, too slow, or with an irregular pattern. Due to the side effects and low bioavailability of many antiarrhythmic drugs, nano-encapsulation has been widely used for their targeted delivery. Lipid nanocapsules, nano liposomes, nano niosomes, solid lipid nanoparticles and polymeric nanoparticles are common nano-carriers used for this purpose. The aim of this article is to summarize some of nano systems used for the specific delivery of antiarrhythmic agents to target tissues. At first, nanotechnology and its applications in drug delivery are described in brief. Then, some information on arrhythmias and antiarrhythmic drugs are provided. Finally, the nano drug delivery systems are explained and examples of their applications in encapsulation of antiarrhythmic drugs are presented.

Expression of S100A12, a small calcium-binding protein, by neutrophils and monocytes/macrophages induces proinflammatory responses via ligation with the receptor for advanced glycation end-products (RAGE) and subsequent activation of intracellular signal transduction pathways such as the nuclear factor (NF)-κB pathway. Although S100A12 has been demonstrated to be a useful biomarker during inflammatory conditions, its precise role in the pathogenesis of renal and cardiovascular diseases has not been fully understood. Recently, several studies have employed S100A12 transgenic mice to investigate its pathological effects. Further studies using these models are required before we can translate these findings to human diseases such as renal and cardiovascular diseases.

OBJECTIVE: Inflammation plays a significant role in the development of ischemic stroke. CXC chemokines play pleiotropic roles in prolonged leukocyte locomotion, astrocyte migration/activation, and neural attachment/sprouting in response to focal stroke. In this study, we aimed to explore the changes in serum levels of three chemokines, C-X-C motif chemokine ligand 1 (CXCL1), C-X-C motif chemokine ligand 9 (CXCL9), and C-X-C motif chemokine ligand 10 (CXCL10), in ischemic stroke patients at the time of admission and before discharge from the hospital ward. MATERIALS AND METHODS: In this study, we recruited 43 unrelated ischemic stroke patients using an easy convenience method or accidental sampling which is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand. We also enrolled 50 genetically unrelated healthy controls showing no history of neurologic, cardiovascular, or inflammatory diseases. Serum levels of the considered chemokines were measured by enzyme-linked immunosorbent assay (ELISA) in patients and healthy controls. RESULTS: No significant difference was observed in ischemic stroke patients following hospitalization and prior discharging from the hospital; however, there was a significant difference in serum levels of CXCL9 and CXCL10 between patients and healthy controls. We also found that the level of the chemokine was not related to gender or medical therapy. It appears that CXCL9 and CXCL10 are more predisposing factors and play a direct role in stroke considering that they were higher in patients than in healthy controls. CONCLUSION: We believe that this study might be used as a basis for further studies on more effective medication regimens to prevent the onset and subsequent complications of stroke. However, these mediators are useful diagnostic and prognostic tools rather than therapeutic tools.
RESUMEN
OBJECTIVE: To compare heart rate variability (HRV) and QT dispersion in comatose patients with normal brainstem function and with brain death. STUDY DESIGN: Cross-sectional comparative study. PLACE AND DURATION OF STUDY: The Intensive Care Unit of Ali-Ebn-Abitaleleb Hopital, Rafsanjan Medical University from September 2007 to June 2009. METHODOLOGY: Fourteen brain death patients with clinical signs of imminent brain death and 15 comatose patients were examined by neurologist in intensive care unit. HRV, RR interval and QT dispersion on ECG were assessed for 24 hours in both groups. Independent t-test and chi-square test were used for statistical analysis to determine significance which was set at p < 0.05. RESULTS: According to Holter findings, mean of standard deviation of RR-interval in the comatose and brain death groups was 48.33 and 35 respectively (p = 0.045). Mean of covariance coefficient of RR-interval was 0.065 in the comatose group and 0.043 in the brain deaths (p = 0.006). QT dispersion was not significant difference in two groups. CONCLUSION: HRV and RR-interval analysis appeared as an early finding for the diagnosis of brainstem death in comparison to comatose patients with normal brainstem function. QT dispersion had not significant in this regard.

AIM: to investigate the relationship between peripheral blood eosinophil count and history of allergy with CAD. METHODS: in a case-control study in Ali-ebn-Abitaleb Educational Hospital of Rafsanjan, Iran, 190 individuals(95 with CAD and 95 without CAD) with mean age of 59.4 +/- 12.6 were investigated. Eosinophil count in peripheral blood, eosinophil leukocyte ratio, neutrophil count and neutrophil/leukocyte ratio were measured. A history of allergy was taken from the participants. RESULTS: there were no significant differences in sex and age among two groups. The mean leukocyte count was 8802.6 +/- 253.3 and 3813.7 +/- 351.9 for case and control groups,respectively; that is, a statistically significant difference,(p<0.05). Eosinophil percent was 1.43% and 0.88% in case and control groups, respectively and this parameter was also significantly higher in case group. History of allergy was not different between the 2 groups. Elevated numbers of eosinophils were observed in Iranian patients with CAD. CONCLUSION: the present results support the theory that eosinophils may have a role in the pathogenesis of ischemic heart disease.
