Background: Previous studies have suggested a significant association between diet quality and mental health. However, a limited number of studies have utilized the Prime Diet Quality Score (PDQS) to examine this association. Additionally, no study has yet compared the PDQS and Healthy Eating Index-2015 (HEI-2015) in terms of their association with depression and anxiety., Aim: This cross-sectional study aimed to investigate the association between diet quality, measured by the PDQS and HEI-2015, and the odds of depression and anxiety in adults., Methods: This study utilized data from the LIPOKAP study, which was conducted between February 2018 and July 2019 in five cities in Iran. We included 1994 adults aged 18 and above who were selected through a multistage cluster sampling method. Participants completed a validated semiquantitative food frequency questionnaire (FFQ) to evaluate their dietary intake. The FFQ was used to calculate the PDQS and HEI-2015. Depression and anxiety levels were determined using the Hospital Anxiety and Depression Scale (HADS)., Results: The participants had a mean age of 39.79 ± 13.87 years, with females accounting for 1,041 (52.2%) of the total population. PDQS showed a significant inverse association with the odds of depression (OR = 0.45, 95% CI: 0.28-0.71) and anxiety (OR = 0.40, 95% CI: 0.25-0.62) in the fully adjusted model. Similarly, the highest quartile of HEI-2015 showed a significantly lower odds of depression (OR = 0.60, 95% CI: 0.40-0.90) and anxiety (OR = 0.62, 95% CI: 0.42-0.92) compared to the lowest quartile., Conclusion: Both PDQS and HEI-2015 were associated with a reduced risk of depression and anxiety. However, the PDQS demonstrated a stronger inverse association with these risks compared to the HEI-2015. This suggests that the PDQS could be a more beneficial dietary pattern for preventing depression and anxiety compared to HEI-2015. Further large-scale studies are required to confirm these findings., (© 2024. The Author(s).)

Objective: With rising demand for soft drinks (SDs) in low-income countries, studies examining mental disorders in relation to SDs are rather scarce. Therefore, we aimed to explore this association in a sample of Iranian adults., Methods: This cross-sectional study was carried out within the framework of the multi-centric LIPOKAP project, with 1970 Iranian healthy adults. Dietary intake and symptoms of depression and anxiety were collected using validated, Persian versions of a food frequency questionnaire and a Hospital Anxiety and Depression Scale (HADS), respectively. Artificial juices were considered fruit-flavored carbonated sugar beverages, sugar-sweetened beverages (SSB) included fruit-flavored carbonated sugar beverages and carbonated colas, and soft drinks included SSB and drinks containing non-nutritive sweeteners., Results: The mean age of the participants was 39.8 ± 13.9 years. Compared to lower intake, higher intake of SDs (OR = 1.30, 95 % CI: 1.01, 1.69; P = 0.041), SSBs (OR = 1.30, 95 % CI: 1.00, 1.67; P = 0.045) and artificial juice (OR = 1.63, 95 % CI: 1.24, 2.13; P < 0.001) was associated with higher risk of depression in adjusted model. These associations were sex-specific and more evident in males. No significant association was found between any of the drinks and anxiety risk except for artificial juice in men which was directly associated with anxiety risk (OR = 1.66, 95 % CI: 1.06, 2.61; P = 0.028)., Conclusion: This study found a positive association between SDs, SSBs and artificial juice and depression, but not anxiety. These associations varied between men and women. Prospective cohort studies are warranted to confirm our results and reveal the causal relationship., Competing Interests: Declaration of competing interest Authors declare that there is no conflict of interest., (Copyright © 2024.

Background: This article introduces the first national guidelines for the management including diagnosis, treatment, and secondary prevention of acute coronary syndrome (ACS) in Iran., Materials and Methods: The members of the guideline development group (GDG) were specialists and experts in fields related to ACS and were affiliated with universities of medical sciences or scientific associations in the country. They carefully examined the evidence and clinical concerns related to ACS management and formulated 13 clinical questions that were sent to systematic review group who developed related evidence using Grade method. Finally the GDG developed the recommendations and suggestions of the guideline., Results: The first three questions in the guideline focus on providing recommendations for handling a patient who experience chest pain at home, in a health house or center, during ambulance transportation, and upon arrival at the emergency department (ED) as well as the initial diagnostic measures in the ED. Subsequently, the recommendations related to the criteria for categorizing patients into low, intermediate and high-risk groups are presented. The guideline addressed primary treatment measures for ACS patients in hospitals with and without code 247 or having primary percutaneous coronary intervention (PCI) facilities, and the appropriate timing for PCI based on the risk assessment. In addition, the most efficacious antiplatelet medications for ACS patients in the ED as well as its optimal duration of treatment are presented. The guideline details the recommendations for therapeutic interventions in patients with ACS and acute heart failure, cardiogenic shock, myocardial infarction with nonobstructive coronary arteries (MINOCA), multivessel occlusion, as well as the indication for prescribing a combined use of anticoagulants and antiplatelet during hospitalization and upon discharge. Regarding secondary prevention, while emphasizing the referral of these patients to rehabilitation centers, other interventions that include pharmaceutical and nonpharmacological ones are addressed, In addition, necessary recommendations for enhancing lifestyle and posthospital discharge pharmaceutical treatments, including their duration, are provided. There are specific recommendations and suggestions for subgroups, such as patients aged over 75 years and individuals with heart failure, diabetes, and chronic kidney disease., Conclusion: Developing guidelines for ACS diagnosis, treatment and secondary prevention according to the local context in Iran can improve the adherence of our health care providers, patients health, and policy makers plans., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Research in Medical Sciences.)

This guideline is the first Iranian guideline developed for the diagnosis, management, and treatment of hyperlipidemia in adults. The members of the guideline developing group (GDG) selected 9 relevant clinical questions and provided recommendations or suggestions to answer them based on the latest scientific evidence. Recommendations include the low-density lipoprotein cholesterol (LDL-C) threshold for starting drug treatment in adults lacking comorbidities was determined to be over 190 mg/dL and the triglyceride (TG) threshold had to be >500 mg/dl. In addition to perform fasting lipid profile tests at the beginning and continuation of treatment, while it was suggested to perform cardiovascular diseases (CVDs) risk assessment using valid Iranian models. Some recommendations were also provided on lifestyle modification as the first therapeutic intervention. Statins were recommended as the first line of drug treatment to reduce LDL-C, and if its level was high despite the maximum allowed or maximum tolerated drug treatment, combined treatment with ezetimibe, proprotein convertase subtilisin/kexin type 9 inhibitors, or bile acid sequestrants was suggested. In adults with hypertriglyceridemia, pharmacotherapy with statin or fibrate was recommended. The target of drug therapy in adults with increased LDL-C without comorbidities and risk factors was considered an LDL-C level of <130 mg/dl, and in adults with increased TG without comorbidities and risk factors, TG levels of <200 mg/dl. In this guideline, specific recommendations and suggestions were provided for the subgroups of the general population, such as those with CVD, stroke, diabetes, chronic kidney disease, elderly, and women., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Research in Medical Sciences.)

Background: The National Persian Registry of Cardiovascular Disease (N-PROVE) has been established to provide a comprehensive database of cardiovascular diseases in the Iranian community for further investigations and to develop national guidelines for the diagnosis, treatment, and prevention of cardiovascular disease (CVD). As with most clinical registries, a quality control audit is necessary to ensure a comprehensive and accurate registry; the current study aims to assess the validity and quality of the N-PROVE/Angiography/Percutaneous Coronary Intervention (PCI) registry., Methods: The current cross-sectional quality assessment study serves as an example of data quality assessment in N-PROVE on a sample of patients registered in the N-PROVE/Angiography/PCI registry since 2020. Accordingly, data of 194 patients, including comorbidities, angiography, and angioplasty characteristics, were collected from the N-PROVE/Angiography/PCI registry as the main database and reevaluated by a panel consisting of a cardiologist and two coronary intervention fellowships as a test database., Results: The quality control of the population-based healthcare database, the N-PROVE/PCI, revealed that the average error rate in terms of comorbidities, angiography characteristics, angioplasty characteristics, and in total were 3.8%, 2.3%, 3%, and 3.03%, respectively., Conclusion: According to the findings of this study, the N-PROVE/PCI registry had an average error of less than 4% in the assessed dimensions, including comorbidities, angiography, and angioplasty characteristics. Therefore, this registry appears valid and may be used for contemporary epidemiological studies., Competing Interests: None.

Background: This study examined the perceived barriers of migrants and refugees to vaccinating their children against measles and polio in Iran., Methods: First, an instrument was developed and validated through several steps. Next, 1,067 parents who had not vaccinated their children against polio and measles or had delayed receiving any dose of these two vaccines until the age of 15 were selected from 16 provinces and completed the instrument. Finally, the data were analyzed., Results: The results of the explanatory factor analysis showed that the perceived barriers affecting vaccination against polio and measles vaccines were categorized into five factors: low knowledge, negative attitude, communication challenges, lack of participation in vaccination programs, and problems related to migration and refugees. Additionally, the results indicated a significant difference in the mean score of perceived barriers based on participants' level of education, economic status, and nationality., Conclusion: The identified barriers may provide a perspective for developing effective efforts in this area. Interventions should focus on parents with low education and poor economic status., (© 2023. The Author(s).)

Purpose: To evaluate the effect of oral magnesium sulfate (MgSO 4 ) on the gene expression and serum levels of inflammatory cytokines including TNF-α, IL-18, IL-1β, IL-6, and IFN-γ in patients with moderate coronary artery disease (CAD)., Methods: 60 CAD patients were selected based on angiography findings and were randomly divided into two groups that received 300 mg/day MgSO 4  (n = 30) or placebo (n = 30) for 3 months. Gene expression and serum levels of inflammatory cytokines were assessed., Results: After 3 months of intervention, gene expression and serum levels of IL-18 and TNF-α in the MgSO 4  group were significantly less than the placebo group (P < 0.05). However, no significant difference in gene expression and serum levels of IL-1β, IL-6, and IFN-γ was observed between the two groups (P > 0.05). In addition, within group analysis demonstrate that Mg-treatment significantly decrease serum level of TNF-α and IL-18 as compared to pretreatment., Conclusion: The results of our study demonstrate that 3-month magnesium sulfate administration (300 mg/day) to CAD patients could significantly decrease serum concentration and gene expression levels of IL-18 and TNF-α. Our findings support the potential beneficial effect of magnesium supplementation on alleviating CAD complications through modulating inflammatory cytokines., (© 2023.

This study aims to provide a comprehensive risk-assessment model including lifestyle, psychological parameters, and traditional risk factors to determine the risk of major adverse cardiovascular events (MACE) in patients with the first acute ST-segment elevation myocardial infarction episode. Patients were recruited from new hospital admissions of acute ST-segment elevation myocardial infarction and will be followed up to 3 years. Clinical and paraclinical characteristics, lifestyle, psychological, and MACE information are collected and will be used in the risk-assessment model. Totally, 1707 patients were recruited (male: 81.4%, mean age: 56.60 ± 10.34). Primary percutaneous coronary intervention was the most prevalent type of coronary revascularization (81.9%). In case of baseline psychological characteristics, mean depression score was 5.40 ± 4.88, and mean distress score was 7.64 ± 5.08. A comprehensive approach, focusing on medical, lifestyle, and psychological factors, will lead to better identification of cardiovascular disease patients at risk of developing MACE through comprehensive risk-assessment models., (Copyright © 2022 Elsevier Inc.

Background: Dietary patterns emphasizing plant foods might be neuroprotective and exert health benefits on mental health. However, there is a paucity of evidence on the association between a plant-based dietary index and mental health measures., Objective: This study sought to examine the association between plant-based dietary indices, depression and anxiety in a large multicentric sample of Iranian adults., Methods: This cross-sectional study was performed in a sample of 2,033 participants. A validated food frequency questionnaire was used to evaluate dietary intakes of participants. Three versions of PDI including an overall PDI, a healthy PDI (hPDI), and an unhealthy PDI (uPDI) were created. The presence of anxiety and depression was examined via a validated Iranian version of the Hospital Anxiety and Depression Scale (HADS)., Results: PDI and hPDI were not associated to depression and anxiety after adjustment for potential covariates (age, sex, energy, marital status, physical activity level and smoking). However, in the crude model, the highest consumption of uPDI approximately doubled the risk of depression (OR= 2.07, 95% CI: 1.49, 2.87; P<0.0001) and increased the risk of anxiety by almost 50% (OR= 1.56, 95% CI: 1.14, 2.14; P= 0.001). Adjustment for potential confounders just slightly changed the associations (OR for depression in the fourth quartile= 1.96; 95% CI: 1.34, 2.85, and OR for anxiety in the fourth quartile= 1.53; 95% CI: 1.07, 2.19)., Conclusions: An unhealthy plant-based dietary index is associated with a higher risk of depression and anxiety, while plant-based dietary index and healthy plant-based dietary index were not associated to depression and anxiety., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Haghighatdoost et al.

Importance: The protein-based SARS-CoV-2 vaccines FINLAY-FR-2 (Soberana 02) and FINLAY-FR-1A (Soberana Plus) showed good safety and immunogenicity in phase 1 and 2 trials, but the clinical efficacy of the vaccine remains unknown., Objective: To evaluate the efficacy and safety of a 2-dose regimen of FINLAY-FR-2 (cohort 1) and a 3-dose regimen of FINLAY-FR-2 with FINLAY-FR-1A (cohort 2) in Iranian adults., Design, Setting, and Participants: A multicenter, randomized, double-blind, placebo-controlled, phase 3 trial was conducted at 6 cities in cohort 1 and 2 cities in cohort 2. Participants included individuals aged 18 to 80 years without uncontrolled comorbidities, coagulation disorders, pregnancy or breastfeeding, recent immunoglobulin or immunosuppressive therapy, and clinical presentation or laboratory-confirmed COVID-19 on enrollment. The study was conducted from April 26 to September 25, 2021., Interventions: In cohort 1, 2 doses of FINLAY-FR-2 (n = 13 857) or placebo (n = 3462) were administered 28 days apart. In cohort 2, 2 doses of FINLAY-FR-2 plus 1 dose of FINLAY-FR-1A (n = 4340) or 3 placebo doses (n = 1081) were administered 28 days apart. Vaccinations were administered via intramuscular injection., Main Outcomes and Measures: The primary outcome was polymerase chain reaction-confirmed symptomatic COVID-19 infection at least 14 days after vaccination completion. Other outcomes were adverse events and severe COVID-19. Intention-to-treat analysis was performed., Results: In cohort 1 a total 17 319 individuals received 2 doses and in cohort 2 5521 received 3 doses of the vaccine or placebo. Cohort 1 comprised 60.1% men in the vaccine group and 59.1% men in the placebo group; cohort 2 included 59.8% men in the vaccine group and 59.9% in the placebo group. The mean (SD) age was 39.3 (11.9) years in cohort 1 and 39.7 (12.0) years in cohort 2, with no significant difference between the vaccine and placebo groups. The median follow-up time in cohort 1 was 100 (IQR, 96-106) days and, in cohort 2, 142 (137-148) days. In cohort 1, 461 (3.2%) cases of COVID-19 occurred in the vaccine group and 221 (6.1%) in the placebo group (vaccine efficacy: 49.7%; 95% CI, 40.8%-57.3%) vs 75 (1.6%) and 51 (4.3%) in cohort 2 (vaccine efficacy: 64.9%; 95% CI, 49.7%-59.5%). The incidence of serious adverse events was lower than 0.1%, with no vaccine-related deaths., Conclusions and Relevance: In this multicenter, randomized, double-blind, placebo-controlled, phase 3 trial of the efficacy and safety of FINLAY-FR-2 and FINLAY-FR-1A, 2 doses of FINLAY-FR-2 plus the third dose of FINLAY-FR-1A showed acceptable vaccine efficacy against symptomatic COVID-19 as well as COVID-19-related severe infections. Vaccination was generally safe and well tolerated. Therefore, Soberana may have utility as an option for mass vaccination of the population, especially in resource-limited settings, because of its storage condition and affordable price., Trial Registration: isrctn.org Identifier: IRCT20210303050558N1.

Purpose: There is a paucity of evidence regarding the influential factors on Iranian children's diet quality. To assess this issue, we explore the relationship between parental diet quality, socioeconomic status (SES), and nutritional knowledge with their children's diet quality using a cross-sectional sample of the Iranian population., Methods: In this study, paired parents along with one of their children (aged 6-18 years old) who lived with them were included. Dietary intake was assessed using a food frequency questionnaire (FFQ) and diet quality was determined using an Alternative Healthy Eating Index-2010 (AHEI). Nutritional knowledge and SES were also explored using validated questionnaires. Multiple linear regression analysis was used and beta (β) and corresponding 95% confidence interval (CI) were reported., Results: After controlling for potential confounders, the parents' AHEI was significantly associated with their children's diet quality (β = 12.34, 95% CI: 10.75, 13.93; P < 0.001). The nutritional knowledge of parents was significantly associated with children's AHEI after controlling for potential confounders (β = 1.63, 95% CI: 0.14, 3.11; P = 0.032). Moreover, the parents' SES was inversely associated with the AHEI of children (β=-3.76, 95% CI: -5.40, -2.11; P < 0.001); however, further adjustment for confounders attenuated this relationship (Model 3: β = 0.87, 95% CI: -0.76, 2.34; P = 0.269)., Conclusions: We found that the children's diet quality could be influenced by their parents' SES, nutritional knowledge, and diet quality. Our findings suggest that improving the nutritional knowledge of parents not only may improve the healthy eating pattern of parents but also could influence their children's diet quality., (© 2023.

Objective: To identify ultra-processed foods (UPF) contribution to daily energy and nutrient intake in Iranians and examine whether UPF intake is associated with nutrient profile and diet quality., Design: In this cross-sectional study, a validated FFQ was used to evaluate usual dietary intake over the preceding year. NOVA system was applied to categorise foods based on their levels of processing. Diet quality was evaluated using the nutrient adequacy ratio (NAR), Nutrient Rich Food Index (NRF) and hybrid nutrient density., Setting: The LIPOKAP study conducted in five cities of Iran (Isfahan, Birjand, Bandar Abbas, Kermanshah and Shahrekord)., Participants: A total of 1994 adults aged ≥18 years were recruited using stratified multistage random cluster sampling method., Results: UPF were responsible for 8·5 % of daily energy intake. In the adjusted model, UPF consumption was inversely associated with carbohydrate, protein, refined and whole grains, fibre, fruit and meat, but was positively linked to energy, total fat, saturated and trans fatty acids and cholesterol. Compared with those in the lowest tertile, individuals in the highest tertile of UPF had smaller NAR for Ca, Mg, Zn, Fe, phosphorus, thiamin, niacin, folate and vitamin C. Both NRF and hybrid nutrient density decreased when the share of daily energy intake from UPF increased., Conclusion: The higher consumption of UPF is associated with poorer diet quality and lower nutrient intake. It is recommended that UPF be replaced with minimally processed foods to improve diet quality and nutrient profile.

Magnesium seems to play a role in improving cardiovascular function, but its exact mechanism is unknown. In this study, we hypothesized that magnesium could modulate the expression of genes involved in atherosclerosis. The aim of the present investigation was to evaluate the effect of magnesium sulfate on the expression of sirtuin1 (SIRT1), tumor protein p53 (TP53), and endothelial nitric oxide synthase (eNOS) genes in patients with atherosclerosis. This study was a placebo-controlled double-blind randomized clinical trial on 56 patients with angiographically proven atherosclerosis. Participants were randomly divided into two groups receiving 300 mg/day magnesium sulfate (n = 29) and placebo (n = 27) for three months (following up every month). Fasting blood samples were taken before and after the intervention and total RNA was extracted and used to evaluate the expression level of SIRT1, TP53, and eNOS genes by Real-Time PCR. The expression of eNOS gene was significantly increased ( P  < 0.0001) and the expression of TP53 gene was decreased ( P  = 0.02) in the magnesium sulfate group compared to the placebo group. But SIRT1 gene expression was not significantly different between the two groups. Our findings demonstrate that magnesium sulfate supplementation may have a protective role against the progression of atherosclerosis through upregulation of eNOS and downregulation of TP53 gene. Trial registration : This present clinical trial has been registered in the Iranian Registry of Clinical Trials (IRCT) with the registration code of "IRCT20151028024756N3", https://www.irct.ir/trial/29097?revision=114102.

Background: Determining cardiovascular disease (CVD) research priorities is essential given the high burden of these diseases, limited financial resources, and competing priorities. This study aimed to determine the research priorities in CVD field in Iran using standard indigenous methods., Materials and Methods: An extensive search was done in relevant international and national studies. Then, an indigenous standard multistage approach based on multicriteria decision analysis steps was adapted to local situation and implemented. This process included forming a working group of experts in priority setting methodology, identifying the context and prioritization framework, discussing the methodology with the National Network of CVD Research (NCVDR) members who ultimately determined the priority research topics, weighted topics criteria, ranked topics, and reviewed all determined research priorities for final report., Results: Thirteen cardiovascular research priorities were determined by the NCVDR members. The first five priorities based on their scores include studies in hypertension, prevention and control of ischemic heart disease (IHD) and its risk factors, burden of IHD, Registration of CVDs, and COVID-19 and CVDs., Conclusion: Cardiovascular research priorities were determined using a standard indigenous approach by national experts who are the NCVDR members. These priorities can be used by researchers and health decision makers., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Research in Medical Sciences.)

There is ambiguity about the airborne transmission of the SARS-CoV-2. While a distance of 6 feet is considered a safe physical distance, new findings show that the virus can be transmitted more than that distance and cause infection. In hospitals, this may cause the virus to be transmitted from the treatment wards of COVID-19 patients to adjacent wards and infect medical staff, non-COVID-19 patients, and patient companions. The aim of this study was to investigate the presence of coronavirus in the air of ICU and adjacent wards. The low volume sampler (LVS) with two separate inlets for PM2.5 and PM10 was applied to collect indoor air of intensive care unit (ICU) with confirmed COVID- 19 patients and its surroundings. The samples were collected on 0.3μ PTFE filter fitted to the holder. Sampling was done at flow rate of 16.7 l/min for 24 h. The SRAS-CoV-2 virus was isolated using a SinaPure™ Virus Extraction Kit (SINACLON, Iran). The presence of SARS-CoV-2 genome was assessed using a commercially available SARS-CoV-2 Test Kit (Pishtaz-Iran), according to the manufacturer's instructions using One Step plus Real-Time PCR system tool (Applied Biosystems, USA). A total of sixteen samples were taken, and the positive test rate for SRAS-CoV-2 was 12.5 % (2/16). All samples from surrounding (rest room and hallway) were negative, but two air samples from indoor of ICU (next to the patient bed and nursing station) were found to be positive. The results support the possibility of transmitting the SRAS-CoV-2 through the air at a greater distance than what is known as a safe physical distance. Therefore, in addition to maintaining a safe physical distance, other precautions including wearing a face mask, preventing air recirculation, and maximizing the use of natural ventilation should be considered, especially in crowded and enclosed environments., (© 2021.

Background: Macronutrients' quality may impact differently on mental health and quality of life (QOL). This study aimed to investigate the potential relationship between the carbohydrate quality index (CQI), fat quality index (FQI), protein quality index (PQI), the affective mental symptoms and QOL among Iranian adults., Methods: The LipoKAP is a cross-sectional study, conducted with 2456 adults in Iran. A validated food frequency questionnaire was used to evaluate usual dietary intakes. A validated Iranian version of the Hospital Anxiety and Depression Scale was used to assess the severity of anxiety and depression. QOL was assessed by EQ-5D., Result: In the fully adjusted model, participants in the highest tertile of CQI had lower QOL than those in the lowest tertile (OR = 1.35; 95 % CI: 1.06, 1.73). Individuals in the top tertile of FQI (OR = 0.71; 95 % CI: 0.55, 0.91) and PQI (OR = 0.78; 95 % CI: 0.60; 1.01) were less likely to report lower QOL than those in the bottom tertile. An inverse association was found between PQI and depressive symptoms (OR = 0.72, 95 % CI: 0.55, 0.95), but not for CQI and FQI., Limitations: The cross-sectional design of the study and the use of a memory-based dietary tool may limit the generalizability of our findings., Conclusion: Higher PQI was associated with lower risk of depressive symptoms and having a low-quality life. Although CQI and FQI were not related to depressive and anxiety symptoms, higher values of FQI were associated with better QOL, while CQI showed an inverse association., (Copyright © 2022 Elsevier B.V.

From December 2019, the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was started as a cluster of pneumonia cases in Wuhan, Hubei Province, China. The disturbing statistics of SARS-CoV-2 promoted scientists to develop an effective vaccine against this infection. NOM protein is a multi-epitope protein that designed based on Nucleocapsid, ORF3a, and Membrane proteins of SARS-CoV-2. Flagellin is a structural protein that binds to the Toll-like receptor 5 and can enhance the immune response to a particular antigen. In this study, NOM protein as vaccine candidate was linked to the carboxyl and amino terminals of flagellin adjuvant derived from Salmonella enterica subsp. enterica serovar Dublin. Then, informatics evaluations were performed for both NOM protein and NOM protein linked to flagellin (FNOM). The interaction between the NOM and FNOM proteins with the TLR5 were assessed using docking analysis. The FNOM protein, which compared to the NOM protein, had a more suitable 3D structure and a stronger interaction with TLR5, was selected for experimental study. The FNOM and Spike (S) proteins expressed and then purified by Ni-NTA column as vaccine candidates. For analysis of immune response, anti-FNOM and anti-S proteins total IgG and IFN-γ, TNF-α, IL-6, IL-10, IL-22 and IL-17 cytokines were evaluated after vaccination of mice with vaccine candidates. The results indicated that the specific antisera (Total IgG) raised in mice that received FNOM protein formulated with S protein were higher than mice that received FNOM and S proteins alone. Also, IFN-γ and TNF-α levels after the spleen cells stimulation were significantly increased in mice that received the FNOM protein formulated with S protein compared to other groups. Immunogenic evaluations showed that, the FNOM chimeric protein could simultaneously elicit humoral and cell-mediated immune responses. Finally, it could be concluded that the FNOM protein formulated with S protein could be considered as potential vaccine candidate for protection against SARS-CoV-2 in the near future., (Copyright © 2022.

Favipiravir (FVP), lopinavir/ritonavir (LPV/RTV), and interferon-beta (INF-beta) are considered as potential treatments for COVID-19. We examined the efficacy and safety of FVP and INF-beta compared to LPV/RTV and INF-beta combinations for the treatment of SARS-CoV-2. It was a single-center randomized clinical trial. Eligible patients were randomized to receive FVP plus INF-beta versus LPV/RTV plus INF-beta. The primary endpoint was the viral clearance after seven days of randomization. ICU admission, length of stay (LOS) in hospital, in-hospital mortality, and the incidence of adverse events were also measured. This trial was registered on the Iranian Registry of Clinical Trials (IRCT20200506047323N3). Patients were randomly allocated to the FVP (n = 33) and LPV/RTV (n = 33) groups. The viral clearance on Day seven was not significantly different between the FVP (31.1%) and the LPV/RTV groups (16.1%). The rate of ICU admission and likewise the in-hospital mortality in the FVP group (12.5% and 6.3%, respectively) were similar to the LPV/RTV groups (19.4% and 19.4%, respectively). The median LOS in the hospital was also not different (6.8 days [interquartile range; IQR = 5.0-11.0] in the FVP and (8.0 days [IQR = 5.5-12.5]) in LPV/RTV groups (p = 0.140). Adverse events were observed in 25.0% of FVP and 32.3% of LPV/RTV groups. The combination therapy with FVP did not exert a higher efficacy compared to the combination regimen of LPV/RTV. However, both treatment regimens demonstrated a mild profile of adverse events., (© 2022 Wiley Periodicals LLC.)

Chronic non-communicable diseases (NCDs), are the leading causes of death among adults worldwide. It is projected that half of the NCDs could be avoided by preventing measures. Under the prospective epidemiological research studies in Iran (PERSIAN), we established a prospective population-based cohort study in southern Iran. The present study was designed to observe changing pattern of lifestyle transition over time and investigate the incidence and prevalence of regional modifiable risk factors as well as their associations with major NCDs. At baseline, 4063 participants aged 35-70 years were recruited on Oct, 2016and planned to get re-evaluated every 5 years along with annual follow-up. Data using validated electronic questionnaire comprising 55 questions and 482 items including general, medical and nutrition queries was collected. Blood, hair, nails, urine specimens and anthropometric measurements were taken. The response rate was 99%. In the results; male and female participants were 42.5% and 57.5%, respectively. Of note, 30.4% of women and 16.1% of men were obese. The prevalence of hypertension in men and women was 14.6% and 21%; however, diabetic men and women were 17.4% and 12.4%, respectively. Living in rural areas increased the odds of having hypertension by 1.33 (AOR = 1.33, 95% CI:1-09, 1.61). Noteworthy, logistic regression displayed that aging could predispose individuals to be more overweight, hypertensive and diabetic. The prevalence of multimorbidity of 3 or more NCDs were 8% (No. 326) and 6% (No.240), respectively. Intake of fruits, vegetables and dairy was less than two servings per day in 9.2%, 13% and 58.3% of the participants. Lower cardiovascular diseases and serum level of FBS and higher HDL level in sailors/fishermen compared to other job groups were significant (p-value <0.001). The second annual follow-up was completed and now at the end of the third wave. Findings of the present study signified the high prevalence of behavioral risk factors and their associations with respective NCDs. Subsequently, it is essential to keep track lifestyle variations, the modifiable risk factors and NCDs trends by prospective population-based cohort studies., Competing Interests: The authors have declared that no competing interests exist.

Background: Vaccination against Covid 19 disease was based on rational practice theory. One of the most effective methods to control the COVID-19 pandemic is extensive vaccination coverage in the shortest time. The relevant beliefs and predictors of COVID-19 vaccine and the barriers to and facilitators of receiving COVID-19 vaccine should be identified. Individuals' intention to receive COVID-19 and the effective factors are of an utmost importance. This study aimed to predict intention to receive COVID-19 vaccine in the South of Iran., Methods: This cross-sectional study was performed over a period of 2 months (May 2021 to July 2021) in 4 southern provinces in Iran. The study population of this study included people over 18 years of age who did not receive the COVID-19 vaccine. The online questionnaire was used to collect data. We recruited participants through a self-selection sampling method and posted the online survey link. The questionnaire had two parts: demographic information and Theory of Reasoned Action (TRA) questions. All statistical calculations and hypotheses tests were performed using SPSS21 and Amos21 software and the significance level was considered 0.05., Results: A total number of 2556 people participated in this study with a mean age of 37.76 (10.7) of years (Age Range = 18-75). The findings showed that attitudes and subjective norms and the use of social media predict the intention to receive COVID-19 vaccine. SEM showed that attitude (β = 0.596, P < 0.001), subjective norms (β = 0.265, P < 0.001) were significant predictors of vaccination intention. In this study, 78% of people were willing to receive the vaccine when they were officially allowed to., Conclusion: According to the results of the study, it is suggested to strengthen positive attitudes and subjective norms about the importance of COVID-19 vaccination as well as using social media to inform the community in order increase the intention to vaccinate COVID-19 and increase vaccine coverage., (© 2022.

Although malaria burden and its active foci have sharply declined after the implementation of elimination programme since 2010, it is still considered as a major public health problem in southeast Iran. This descriptive-analytical study aimed to determine 10-years of malaria epidemiological trends in Bashagard County. Data were collected from 7 selected malarious region of the county based on active and passive surveillance of clinical cases. For diagnosis of malaria, the examination of microscopic slides and rapid diagnostic test, were used. In total, 237 malaria cases were found from 2009 to 2018. Plasmodium vivax was the dominant parasite species and identified in 232 (97.9%) individuals. Males were infected more than females and the majority of malaria cases (67.4%) were recorded from rural areas. Although about 98% of malaria cases were indigenous, they have decreased form 200 cases in 2009 to zero indigenous transmission in 2018. During the study period, malaria cases had decreased significantly by about 99% and the incidence rate had declined from 5.47/1000 cases in 2009 to 0.002/1000 in 2018. The incidence of malaria, especially indigenous cases, in Bashagard County has decreased dramatically in the past 10 years. However, there is still probability of malaria re-introduction and outbreak in the county due to climatical and geographical conditions. Therefore, it is necessary to implement an active surveillance system to detect and treat malaria cases quickly, during the elimination phase in this county., Competing Interests: Conflict of interestThe authors declare that they have no competing interests., (© Indian Society for Parasitology 2021.)

Background: Patients who undergo percutaneous coronary intervention (PCI) receive anticoagulants, most commonly heparin to prevent thrombotic events during the procedure. Opioid addicts may require higher doses of heparin for PCI. We aimed to compare the effect of heparin on activated clotting time (ACT) between opioid addicts and non-addicts prior to and during PCI., Methods: This comparative study included 107 patients scheduled for elective PCI, of whom 50 were opioid addicts and 57 non-addicts. Patients' baseline characteristics including age, gender, weight, comorbidities, drug history, and smoking were recorded. Prothrombin time (PT), ýpartial thromboplastin time (PTT), international normalized ratio (INR), and platelet count were measured in venous blood samples collected from all participants. All patients underwent PCI through femoral access. They received 100 IU/kg heparin right at the beginning of the procedure. ACT was measured at 2 and 30 minutes., Findings: Age, gender, weight, and the amount of heparin used were comparable between groups. As for general characteristics, the number of patients with hyperlipidemia was significantly higher in non-addicts (P = 0.031), and cigarette smoking was higher in opioid addicts (P < 0.001). No significant difference was found between the groups regarding PT, PTT, INR, and platelet count (P > 0.050). ACT at 2 and 30 min were significantly lower in opioid addicts (P < 0.001). Taking other variables into account, ACT at 2 min was directly correlated with drug history of aspirin in opioid addicts (P = 0.031) and inversely correlated with cigarette smoking in non-addicts (P = 0.023)., Conclusion: Opioid addicts may require higher doses of heparin in PCI for the prevention of thrombotic complications compared to non-addicts., (©2021 Kerman University of Medical Sciences.)

Purpose    Here, for the first time, the possible association between IL-25 and the risk of acute coronary syndrome (ACS) in Iranian patients was investigated.Material and methods    In this study, serum IL-25 concentrations were measured with an enzyme-linked immunosorbent assay in 88 ACS patients, 40 stable angina pectoris (SAP) patients, and 50 healthy control subjects.Results    No significant differences in IL-25 concentrations were observed between SAP (340±168 ng / l), ACS (330±151 ng / l), and control (302±135 ng / l) groups (p=0.5), nor was there a difference among patients with 1, 2, or 3 vessel disease in the SAP and ACS groups. Linear regression analyses revealed that IL-25 was not correlated with coronary artery disease risk factors. Biochemical and demographic variables did not differ significantly among IL-25 quartiles.Conclusion    Despite previous murine and human studies showing a protective role of IL-25 in atherosclerosis, our results revealed that IL-25 does not have potential implications for atherosclerosis development and management in humans.

We aimed to present the methodology of a national registry entitled "Persian CardioVascular Disease Registry (PCVDR)." Persian Registry Of cardioVascular diseasE (PROVE) was a demonstration registry conducted in Isfahan since 2014 to test the feasibility and practicality of PCVDR in Iran. Built on that experience, the first phase of PCVDR that consist of angiography and percutaneous coronary intervention (PCI) registry at national level started in March 2017. Currently, PCVDR is in place in 19 hospitals, located in 7 provinces. Five questionnaires including basic information, angiography, and PCI techniques, discharge and follow-up were completed for registered patients. Since beginning until October 7th, 2019, the number of angiography and PCI cases registered in all provinces were 37,120 and 16,277, respectively. Of all PCI cases registered, 11,846 patients (72.8%) were followed up until 12 months. We expect that this registry be expanded to cover most hospitals and centers with cardiology departments in the country., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: With the onset of the coronavirus disease-2019 (COVID-19) pandemic, hospitalization and treatment of non-covid patients decreased worldwide. The aim of this study is to evaluate the admission and treatment of patients with coronary artery diseases (CADs) by examining coronary Cath labs activities in some centers of Iran during the COVID-19 period., Methods: A retrospective, multi-center survey was conducted in four cites in Iran which participated in National Persian Registry Of CardioVascular diseasE (N-PROVE). Two periods of COVID-19 occurrence peak in Iran were compared with the same date in 2019. Information was collected on the number of diagnostic and therapeutic coronary catheterizations in both stable ischemic heart diseases (SIHDs) and acute coronary syndrome (ACS) settings., Results: In the first peak of COVID-19 pandemic, coronary angiographies and angioplasties decreased by 37 and 38% compared to the same period in 2019, respectively. The most common indication for coronary angiography during this period was ACS [especially ST-Segment Elevation Myocardial Infarction (STEMI)]; however, at the time of peak decrease, the SIHDs were the most. In the second peak of COVID-19 pandemic in Iran, 34% and 27% decrease in diagnostic and therapeutic coronary procedures were seen, respectively. During this period, the number of elective admissions increased, although it was still lower than that in 2019. The tendency to rescue percutaneous coronary intervention increased in most centers during the COVID-19 era, especially in the second peak., Conclusion: A significant reduction in the coronary Cath lab activity has been observed during the COVID-19 pandemic that can indicate an increased risk of cardiovascular mortality and morbidity., (© 2021 Isfahan Cardiovascular Research Center & Isfahan University of Medical Sciences.)

Background: Neuregulin 4 (Nrg4) is a novel adipocytokine that has been proposed to play a role in modulating energy metabolism and pathogeneses of atherosclerosis. However, no published research is available about the mechanisms underlying the anti-atherosclerotic effect of Nrg4. Regarding the close link between adipocytokines and the immune system, we wonder whether there is a relation between Nrg4 and athero-protective cytokines. The aim of this study was to investigate the relationship between serum Nrg4 levels and type 2 cytokines in Iranian patients with coronary artery disease (CAD)., Methods: In this case-control study, 125 CAD patients were compared to 55 healthy controls. The serum concentrations of Nrg4, IL-5, IL-9, and IL-13 were measured using ELISA. The associations of circulating Nrg4 and IL-5, IL-9, IL-13 were assessed using linear regression analyses., Results: Serum concentration of IL-9 was significantly higher in patients compared to the healthy controls (317.9±139 versus 228.3±99.1, P= ˂0.0001). IL-13 and Nrg4 were significantly lower in patients compared to the healthy controls (4.3±3.7 versus 6.1±3.9, P=0.01 and 0.5 versus 1.3, P=0.001 respectively). Multiple linear regression analyses revealed that IL-9 was negatively correlated with Nrg4 (β= -0.3, P=0.009)., Conclusion: Our study, for the first time, provides the clinical evidence revealing that circulating Nrg4 concentrations are inversely correlated with IL-9 in Iranian patients with CAD, suggesting that the protective role of Nrg4 on atherosclerosis may be, in part, mediated by the proatherogenic cytokine, IL-9., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Purpose: Given the beneficial effect of MgSO 4 on the cardiovascular system, this study was designed to investigate the effect of MgSO 4 administration on suppressing some atherosclerotic risk factors in moderate coronary artery disease patients with one or two atherosclerotic vessels., Patients and Methods: In a randomized double-blind placebo-controlled clinical trial study, 64 patients with moderate coronary artery disease (55-69% stenosis) were selected according to angiography findings. Patients were divided into four groups including patients with one or two atherosclerotic vessels treated with MgSO 4 (Mg-treated-VR1, Mg-treated-VR2, respectively), placebo treated patients with one or two atherosclerotic vessels (Control-VR1, Control-VR2, respectively). The patients received either placebo or MgSO 4 supplement capsule containing 300 mg MgSO 4 for six months on a daily basis. ESR, Ca/Mg ratio, urine Mg level, serum Mg, fibrinogen, homocysteine, uric acid, Na, K, Ca, CRP, T3, T4, TSH, BUN, and Cr concentrations were measured at baseline and every three months., Results: Serum T3, Ca, K, homocysteine, CRP, and Mg concentrations were significantly improved in Mg-treated groups compared to placebo groups., Conclusion: The results of this study showed that despite the slight change in serum magnesium level, oral administration of MgSO 4 for six months could slightly reduce the serum levels of some inflammatory and vascular factors in moderate coronary artery disease patients., Competing Interests: The authors report no conflicts of interest in this work., (© 2020 Sobhani et al.)

Magnesium (Mg) deficiency is known to promote vascular and cardiac dysfunctions such as atherosclerosis. This study investigated the effect of oral MgSO4 therapy to improve lipid profile and serum oxidized LDL level and its receptor (LOX1) in moderate coronary atherosclerotic patients. In this randomized double-blind placebo-controlled clinical trial study, 64 patients with moderate coronary artery disease were selected according to angiography findings. Participants were divided into 2 groups including Mg-treated (n = 32) and placebo (n = 32) The patients received either placebo or MgSO4 supplement capsule, containing 300 mg MgSO4 for 6 months on a daily basis. Lipid profile, HbA1c, 2h postprandial (2hpp) blood glucose, fasting blood sugar, serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), oxidized low-density lipoprotein, and lectin-like ox-LDL receptor 1 (LOX1) concentrations were measured at baseline and every 3 months. HbA1c, serum LOX1, and oxidized low-density lipoprotein concentrations were significantly lower in the Mg-treated group than the placebo group 3 months after MgSO4 administration. 2hpp, serum low-density lipoprotein cholesterol, SGPT, SGOT levels, and HbA1c levels significantly improved in the Mg-treated group compared with the placebo-received group. Overall, the results of this study showed that magnesium treatment improved some of the major risk factors of atherosclerosis. According to the results of liver function tests (SGOT and SGPT), magnesium therapy seems to be safe in patients with moderate atherosclerotic plaque. Therefore, it is suggested that magnesium to be used along with other atherosclerosis control drugs.

Endothelial Nitric Oxide Synthase (eNOS) is an indispensable regulator of blood pressure through producing Nitric Oxide (NO). There is some evidence to suggest that eNOS gene polymorphisms are associated with Essential Hypertension (EHT). In this study, the potential association between eNOS 4a/4b, A922G, G894T, T786C gene polymorphisms and EHT as individual risk factors and as haplotypes are examined in the southern population of Iran (Bandar-Abbas). In this study, 200 EHT patients and 200 normotensive subjects which were matched for age and sex were included. Genotyping was performed by either utilizing Polymerase Chain Reaction (PCR) or PCR followed by Restriction Fragment length Polymorphism (RFLP) method. Our results demonstrated statistically significant associations between T786C, G894T, and 4a/4a and EHT (p < 0.05); however, A922G had no significant association with EHT (p > 0.05). Haplotype analysis also suggested that - 786C/- 922A/4a, - 786C/- 922A/4b and - 786C/- 922G/4a haplotypes were more frequent in EHT group than control group, hypothesizing a positive association with EHT. The present study has identified that the eNOS genetic variations are associated with EHT in southern population of Iran (Bandar-Abbas). These findings also suggested that a number of haplotypes of eNOS gene may be a driving factor for EHT susceptibility in respected population.

Acute coronary syndrome (ACS) is closely associated with an increased risk of death. Nrg4, a novel adipocytokine, has negative correlations with indicators of metabolic syndrome. Here, we investigated whether circulating Nrg4 associates with the prevalence of ACS. In this case-control study, a total of 257 subjects (144 patients with ACS and 56 patients diagnosed with stable angina pectoris (SAP)) compared to 57 healthy controls. Serum Nrg4 and hs-CRP concentrations were determined by ELISA. The associations of circulating Nrg4 with other clinical parameters were also analyzed. Serum levels of Nrg4 were lower in patients compared to the control subjects (0.7 ± 0.53 ng/mL versus 1.1 ± 0.9 ng/mL, P = 0.018). There was a significant association between higher Nrg4 level and lower risk of ACS (OR = 0.15; 95%CI = 0.02-0.9; P = 0.046), but not with SAP. This association was independent of potential confounders including traditional cardiovascular risk factors. The distribution of patients with no, 1, 2 and 3 vessel stenosis was significantly different in Nrg4 quartiles. Patients in the lower quartile of Nrg4 were more likely to experience 3 vessel diseases. Serum levels of Nrg4 correlated negatively with HDL-cholesterol in ACS patients. Decreased serum levels of Nrg4 might be an independent risk factor for ACS.

Background: Hypertension is a common risk factor for developing cardiovascular, brain, and kidney disorders; and today, it affects about one billion people worldwide. Insufficient clinical knowledge of the practitioners and family physicians and not following the guidelines has led to the improper control of hypertension. This study intended to investigate the knowledge, attitude, and practice of general practitioners (GPs) about hypertension in Hormozgan province, Iran., Methods: This cross-sectional study used consecutive sampling method. A three-part researcher-made questionnaire was used to collect data on demographic, attitude, knowledge, and practice information from 220 GPs working in Hormozgan province., Results: The mean and standard deviation (SD) of scores on knowledge, practice, and attitude of GPs about hypertension management were (5.00 ± 0.50), (10.00 ± 0.02) and (9.00 ± 0.15), respectively; which present a proper state. Attending training courses and increased work experience have statistically significant effects on the knowledge and attitude of GPs (P < 0.050). The only exception was the area of practice, where there was no significant relationship between the practitioners' work experience and their practice (P = 0.266)., Conclusion: The results of this study can be utilized by decision-makers and general medicine curriculum designers to plan effective training courses for medical graduates to be used in clinical settings for health promotions.

Background: Percutaneous coronary intervention (PCI) is the most common revascularization procedure, with over 1 million performed each year, worldwide. Over the past 20 years, the increasing experience of operators coupled with the advent of newer technologies, including coronary stents and a variety of adjuvant drug therapies, have permitted more successful procedures and decreased the morbidity associated with PCIs., Objective: To identify the incidence, predictors, and clinical implications of Major Adverse Cardiovascular Events (MACE) after PCIs., Methods: This descriptive cross-sectional study was done in Bandar Abbas in Iran in 2015. All patients which treated with PCI in Shahid Mohammadi Hospital during a one-year period were employed. A total of 192 patients were included. At one-year follow-up in this study, incidence and predictors of MACE were evaluated in a prospective study. The data were analyzed by SPSS 19.0 and descriptive tests included frequency and percentage and mean and standard deviation. Also, Chi-square test was used for data analysis. A p value <0.05 was determined as significant., Result: Of the 192 patients, 126 (65.6%) were men and 66 patients were female. Stent had been implemented in 93.8% of patients. Sixty two percent of patients were treated with only one stent, two stents were deployed in 29.7% of patients and 3.6% of patients were treated with three or more stents. Of these patients, 46.9% were treated with Drug Eluted Stent (DES) and 40.1% were treated with Bare Metal Stent (BMS). Both types of stents were used in 8.3% of patients. Also, 4.7% of the patients were treated with balloon angioplasty (POBA). Angioplasty success rate was 95.3% and procedural success rate defined as achieving TIMI III flow with residual coronary stenosis under 30%. No in-hospital mortality or emergency CABG was reported. Re-admission in first year after PCI was required in 34 (17.7%) patients of which, 20 of them (10.4%) needed target vessel revascularization (TVR). Readmission was significantly higher (p=0.034) in the group with BMS compared to those who had DES. MI occurred in 8 patients., Conclusion: Our study showed the superiority of DES in comparison with BMS in decreasing readmission and less TVR, but no effect on long term mortality. We recommend more studies in this setting because patients in special groups may benefit more from DES or BMS., Competing Interests: Conflict of Interest: There is no conflict of interest to be declared.

Background: Recent studies have reported an association between periodontitis and cardiovascular diseases. Atherosclerosis is also a risk factor for cardiovascular diseases. IL-6 and CRP are important inflammatory markers that are important because they have been shown to be higher when a patient has periodontitis, and they are related to atherosclerosis. The aim of this study was to assess the relationship between periodontitis and CRP and IL-6 in atherosclerotic patients., Methods: The study population in this case control study was atherosclerotic patients in Bandar Abbas, Iran in 2014. The participants included 30 individuals with periodontal diseases and 30 individuals without periodontal diseases, and they were allocated into two groups according to probe depth (PD) and clinical attachment loss (CAL). Inflammatory markers, including CRP and IL-6 were measured in the two groups. The data were analyzed using IBM SPSS 21 statistical software. Descriptive statistics, chi-squared, independent samples t-test, and Mann-Whitney tests were used to analyze the data., Results: Individuals with abnormal CRP had significantly higher PD and CAL than individuals with normal CRP (P<0.001). Although PD was not significantly different in individuals with normal and abnormal IL-6 (P=0.124), CAL was significantly higher in individuals with abnormal IL-6 than in the other individuals (P=0.005)., Conclusion: The results of this study showed that CRP and IL-6 are associated with periodontal diseases in atherosclerotic patients. Treatment of periodontal diseases is recommended in atherosclerotic patients.

Background: Treatment of patients with acute myocardial infarction (AMI) is time related, so delay in treatment could affect prognosis. Recognizing pre-hospital or in-hospital delays in initiating treatment and reducing these factors is very efficacious in treatment of these patients., Objectives: The aim of this study is evaluate the causes of pre-hospital delay just as other studies on effect of different variables such as socioeconomic and personal factors on pre-hospital delay in with patients with AMI., Materials and Methods: A cross sectional study was carried out on 227 patients with acute myocardial infarction and demographic data, educational level, marital status, type of transfer to hospital and delay in arrival to hospital were recorded., Results: 35.7% patients arrived during one hour of symptom onset, and 7.9% arrived after 24 hours. Patients having high level education (P = 0.0492) and with a family history of coronary artery disease (P = 0.01) had significantly less delay in arriving to hospital. Age, marital status, gender, and route of transfer to hospital were not related with pre-hospital delay (P > 0.05). Patients thought most common cause of delay in arrival was unawareness of coronary artery disease (38.8%) and self-medication (34.3%)., Conclusions: Increasing awareness of patients about cardiovascular symptoms and their risk factors could be helpful in patient's decision in seeking medical help. So general education via media and primary and middle schools could be helpful.

Introduction: End-stage renal disease causes impairment of all body organs including the heart and the lung. The main problems in the afflicted patients are pulmonary edema due to increased permeability of the capillaries, intravascular and interstitial volume overload, hypertension, and congestive heart failure. These changes cause altered physiologic and mechanical function of the lungs and subsequently increase in airway resistance. We aimed to study the impact of hemodialysis on spirometry parameters., Materials and Methods: In a cross-sectional study performed on 41 patients on maintenance hemodialysis, spirometry was done before and after the dialysis session. The patients were on either acetate or bicarbonate hemodialysis with the same method, dialysis machine, and duration of dialysis. Alterations in spirometry parameters including forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, and maximal midexpiratory flow rate were determined and their relation with serum electrolytes, serum creatinine, blood urea nitrogen, and hemoglobin were analyzed., Results: Twenty-nine patients undergoing dialysis with bicarbonate dialysate and 21 on dialysis with acetate were compared. Improvement in spirometry parameters was only significant in patients undergoing dialysis with bicarbonate dialysate. All spirometry parameters showed significant increases in the bicarbonate group except for the FEV1/FVC ratio. Furthermore, significant increase in these parameters was only prominent in the men. Postdialysis weight reduction and laboratory indexes had no significant correlation with improvement of spirometry parameters., Conclusions: Dialysis with bicarbonate dialysate causes significant improvement in spirometry parameters in men on maintenance dialysis. This effect might be independent of the effect of removing the volume overload by dialysis.
