The effects of opium consumption on severity of disease on hospitalized COVID-19 patients in East of Iran, a prospective cohort study

There are few theories and little empirical evidence about the bilateral impact of substance use and coronavirus disease 2019 (COVID-19), so a logical and accurate picture of this area is required. We investigated the effects of opium use on severity of disease on hospitalized COVID-19 patients in east of Iran. Demographic and clinical characteristics, vital signs, laboratory tests, mortality rate, type and duration of opium consumption in hospitalized patients who recovered from COVID-19 in the follow-up after 3 months were evaluated. In this study, 60 (20%) participants were the opium user and 251 (80%) were the non-user patients. Based on clinical symptoms, hypertension and systolic blood pressure in opium user were significantly higher than non-user patients (p < 0.05). In the laboratory tests, only the level of urea was higher in the opium positive group (37 [26.5-48.5] vs. 32 [23-43], respectively) and the percent of lymphocytes were lower in the opium positive (17 [8.2-25.8] vs. 18.7 [13.85-26.35], respectively). The initial therapies of both opium positive and negative infected patients showed not any significant changes (p > 0.05). Among the studied groups, one deceased case with COVID-19 was related to a drug user patient. Although, uses of opium reduced the levels of some risk factors, vital signs at admission and initial therapies during hospitalization in COVID-19 patients but it increased lung and heart diseases. Also, the severity of COVID-19 including hospitalization and mortality were associated with opium consumption.

Which risk factor best predicts coronary artery disease using artificial neural network method?

BACKGROUND

Coronary artery disease (CAD) is recognized as the leading cause of death worldwide. This study analyses CAD risk factors using an artificial neural network (ANN) to predict CAD.

METHODS

The research data were obtained from a multi-center study, namely the Iran-premature coronary artery disease (I-PAD). The current study used the medical records of 415 patients with CAD hospitalized in Razi Hospital, Birjand, Iran, between May 2016 and June 2019. A total of 43 variables that affect CAD were selected, and the relevant data was extracted. Once the data were cleaned and normalized, they were imported into SPSS (V26) for analysis. The present study used the ANN technique.

RESULTS

The study revealed that 48% of the study population had a history of CAD, including 9.4% with premature CAD and 38.8% with CAD. The variables of age, sex, occupation, smoking, opium use, pesticide exposure, anxiety, sexual activity, and high fasting blood sugar were found to be significantly different among the three groups of CAD, premature CAD, and non-CAD individuals. The neural network achieved success with five hidden fitted layers and an accuracy of 81% in non-CAD diagnosis, 79% in premature diagnosis, and 78% in CAD diagnosis. Anxiety, acceptance, eduction and gender were the four most important factors in the ANN model.

CONCLUSIONS

The current study shows that anxiety is a high-prevalence risk factor for CAD in the hospitalized population. There is a need to implement measures to increase awareness about the psychological factors that can be managed in individuals at high risk for future CAD.

Evaluation of the effect of the COVID-19 pandemic on the all-cause, cause-specific mortality, YLL, and life expectancy in the first 2 years in an Iranian population-an ecological study

Background

COVID-19 pandemic resulted in excess mortality and changed the trends of causes of death worldwide. In this study, we investigate the all-cause and cause-specific deaths during the COVID-19 pandemic (2020-2022) compared to the baseline (2018-2020), considering age groups, gender, place of residence, and place of death in south Khorasan, east of Iran.

Methods

The present ecological study was conducted using South Khorasan Province death certificate data during 2018-2022. The number of death and all-cause and cause-specific mortality rates (per 100,000 people) were calculated and compared based on age groups, place of residence, place of death, and gender before (2018-2020) and during the COVID-19 pandemic (2020-2022). We also calculated total and cause-specific years of life lost (YLL) to death and gender-specific life expectancy at birth.

Results

A total of 7,766 deaths occurred from March 21, 2018, to March 20, 2020 (pre-pandemic) and 9,984 deaths from March 21, 2020, to March 20, 2022 (pandemic). The mean age at death increased by about 2 years during the COVID-19 pandemic. The mortality rate was significantly increased in the age groups 20 years and older. The most excess deaths were recorded in men, Aged more than 60 years, death at home, and the rural population. Mortality due to COVID-19 accounted for nearly 17% of deaths. The highest increase in mortality rate was observed due to endocrine and Cardiovascular diseases. Mortality rates due to the genitourinary system and Certain conditions originating in the perinatal period have decreased during the COVID-19 pandemic. The major causes of death during the pandemic were Cardiovascular diseases, COVID-19, cancer, chronic respiratory diseases, accidents, and endocrine diseases in both sexes, in rural and urban areas. Years of life lost (YLL) increased by nearly 15.0%, which was mostly due to COVID-19, life expectancy at birth has steadily declined from 2018 to202 for both genders (from 78.4 to 75).

Conclusion

In this study, we found that All-cause mortality increased by 25.5% during the COVID-19 pandemic, especially in men, older adult, Rural residents, and those who died at home (outside the hospital). Considering that the most common causes of death during the COVID-19 pandemic are also non-communicable diseases. It is necessary to pay attention to non-communicable diseases even during the pandemic of a serious infectious disease like COVID-19. The years of life lost also increased during the COVID-19 pandemic, which is necessary to pay attention to all age groups, especially the causes of death in young people. In most developing countries, the first cause of death of these groups is accidents.

Prevalence of Metabolic Syndrome and Its Associated Potential Factors among the Elderly in the East of Iran

BACKGROUND AND AIMS

This cross-sectional study aimed to determine potential factors with a strong association with metabolic syndrome (MetS) among obesity and lipid-related parameters, and liver enzymes, fasting blood glucose (FBG), and blood pressure (BP) as well as some sociodemographic factors in elderly over 60 years old from a sample of Birjand Longitudinal Aging Study (BLAS).

METHODS

A total of 1366 elderly Birjand participants were enrolled and divided into non-MetS (n = 512) and MetS (n = 854) groups based on the status of MetS from January 2018 to October 2018. The anthropometric parameters, blood lipid profiles, liver enzymes, and disease history were evaluated and recorded.

RESULTS

62.5% of the participants from our sample of elderly Birjand have MetS (33.4% in males and 66.6% in females). The prevalence of MetS in females was significantly higher than in males (P < 0.001). The increasing trend in the number of MetS components (from 0 to 5) was observed in females (p < 0.001). Odds ratio showed a strong association between female gender [8.33 (5.88- 11.82)], obesity [8.00 (4.87-13.14)], and overweight [2.44 (1.76-3.40)] with MetS and acceptable association between TG/HDL [(1.85 (1.62-2.12)] with MetS.

CONCLUSION

This study indicated that the female sex, overweight and obesity have a strong association with MetS and TG/HDL has an acceptable association found in the sample of the elderly Birjand population. However, due to the obvious limitations of our study including the homogeneous sex and race of population, and no adjustment for several important confounding factors including sex, different ages, stage in the elderly, alcohol consumption, smoking, married status, physical activity, diet, and family history of CVD, more epidemiological investigations are needed to address this question.

Medium-chain acyl-CoA dehydrogenase deficiency (MCADD) precipitating unexpected death in an infant: Report of a case and a brief review of literature

Medium-chain acyl CoA dehydrogenase deficiency (MCADD) and other inborn errors of metabolism are common causes of Sudden Unexpected Deaths in Infancy (SUDI). If identified early or before metabolic decompensation, MCADD is manageable. In the US and other countries, identification of MCADD has improved through the routine use of newborn screening (NBS), which is able to identify most cases. This case study presented here occurred before NBS was implemented in Ohio for MCADD and outlines the typical clinical presentation, pathological features, and relevant biochemical and molecular markers for identifying MCADD. Genetic counselling should be sought for the family if MCADD is identified.

Trace element concentration and cognitive dysfunction in elderly residents in Birjand

Trace elements were suggested to have a main role in modulating cognitive function. However, there are several controversial findings regarding the association between serum trace element concentration and cognitive function in patients with cognitive disorders. Thus, this study aimed to evaluate the changes in serum trace element concentrations in elderly with cognitive dysfunction versus the participants with normal cognitive function. This cross-sectional study included 191 older adults over 60 years from Birjand County, Iran. Participants were assessed for cognitive performance and serum trace elements concentration including aluminum (AL), cobalt (Co), cadmium (Cd), Chrome (Cr), copper (Cu), Iron (Fe), magnesium (Mg), manganese (Mn), selenium (Se) and zinc (Zn). Our findings showed no significant difference in the serum concentration of AL, Co, Cr, Zn, Fe, Mg, Mn, and Se of elderly with cognitive dysfunction versus the subjects with normal cognitive function. However, the concentration of Cu significantly increased in the serum of the elderly with cognitive dysfunction versus participants with normal function. In conclusion, our study indicated an increase in the serum concentration of Cu in the elderly with cognitive dysfunction in the sample of the Birjand Longitudinal Aging Study. However, due to the main limitations of our study including low sample size and cross-section design, these findings should be interpreted with caution.

COVID-19 cases, hospitalizations and deaths after vaccination: a cohort event monitoring study, Islamic Republic of Iran

Objective

To investigate the incidence of coronavirus disease 2019 (COVID-19) cases, hospitalizations and deaths in Iranians vaccinated with either AZD1222 Vaxzevria, CovIran® vaccine, SARS-CoV-2 Vaccine (Vero Cell), Inactivated (lnCoV) or Sputnik V.

Methods

We enrolled individuals 18 years or older receiving their first COVID-19 vaccine dose between April 2021 and January 2022 in seven Iranian cities. Participants completed weekly follow-up surveys for 17 weeks (25 weeks for AZD1222) to report their COVID-19 status and hospitalization. We used Cox regression models to assess risk factors for contracting COVID-19, hospitalization and death.

Findings

Of 89 783 participants enrolled, incidence rates per 1 000 000 person-days were: 528.2 (95% confidence interval, CI: 514.0-542.7) for contracting COVID-19; 55.8 (95% CI: 51.4-60.5) for hospitalization; and 4.1 (95% CI: 3.0-5.5) for death. Compared with SARS-CoV-2 Vaccine (Vero Cell), hazard ratios (HR) for contracting COVID-19 were: 0.70 (95% CI: 0.61-0.80) with AZD1222; 0.73 (95% CI: 0.62-0.86) with Sputnik V; and 0.73 (95% CI: 0.63-0.86) with CovIran®. For hospitalization and death, all vaccines provided similar protection 14 days after the second dose. History of COVID-19 protected against contracting COVID-19 again (HR: 0.76; 95% CI: 0.69-0.84). Diabetes and respiratory, cardiac and renal disease were associated with higher risks of contracting COVID-19 after vaccination.

Conclusion

The rates of contracting COVID-19 after vaccination were relatively high. SARS-CoV-2 Vaccine (Vero Cell) provided lower protection against COVID-19 than other vaccines. People with comorbidities had higher risks of contracting COVID-19 and hospitalization and should be prioritized for preventive interventions.

Prevalence and factors connected with chronic diseases in the elderly residents of Birjand: a community - based study in Birjand, South Khorasan Province, Iran

OBJECTIVES

The rapid rise of non-communicable diseases (NCDs) across the elderly has attracted much attention in Iran due to the high rate of population aging in the country. The current survey intended to evaluate the prevalence of and factors associated with five NCDs in the elderly residents of Birjand, a metropolis of South Khorasan, Iran.

METHODS

Following an observational design, 1820 elderly dwellers of Birjand aged ≥ 60 years residing in urban or rural areas were explored. Data on the target NCDS and socio-demographic features, health behavioral factors, and objective assessment of height and weight were collected using interviews.

RESULTS

The prevalence of hypertension, diabetes mellitus, chronic obstructive pulmonary disease (COPD), stroke, and cancer was 55.2% (1004/1819), 25.5% (463/1819), 1.0% (18/1807), 4.4% (80/1810), and 1.8% (33/1816), respectively. There was no gender difference concerning the prevalence of COPD, whereas the prevalence of hypertension, diabetes mellitus, and cancer was higher in women than men. Stroke was conversely higher in males than females. The common correlations of the five main NCDs were locality of residence and low body mass index (BMI). Rural residents had higher odds of diabetes mellitus and hypertension and lower odds of stroke. Diabetes mellitus, hypertension, and stroke were associated with a low BMI. Gender, age, and occupation were found to be associated with some of the NCDs. Retired and housewives had more chance to have hypertension and diabetes mellitus than the unemployed elderly.

CONCLUSION

The findings demonstrated that hypertension, diabetes mellitus, and stroke are the three prevalent NCDs among elders in the area and warrant a specific focus on reducing the burden of diseases and aligning healthcare services to prepare the whole needs of this population.

Gym and home-based combined training in men with primary hypertension: are they equally effective on functional fitness profile, body composition components, and biochemical parameters of hypertension?

OBJECTIVE

This study aimed to compare the effects of 10 weeks of gym versus home-based combined training on the functional fitness, body composition, and biochemical parameters of hypertension in primary hypertensive men.

METHODS

Forty-six patients (age 48 ± 9 years, BMI 30 ± 4 kg/m²) assigned into three groups: a gym-based combined training (GBCTr: n = 16; resistance at 60-80% of 1RM, using pin-loaded resistance equipment, aerobic at 40-60% HRR, and stretching), home-based combined training (HBCTr: n = 15; resistance at 12-15 RPE, using an elastic exercise band, aerobic at 40-60% HRR, and stretching), and control (CTR, n = 15).

RESULTS

Following GBCTr and HBCTr, the functional aerobic capacity (P = .005 and P = .004, respectively), flexibility (P = .01 and P = .004, respectively), and lower limb muscle strength (P = .01 and P = .02, respectively) was increased significantly compared with the CTR group. The body weight (P = .02), body mass index (P = .008), hip circumference (P = .02), and nitric oxide level in GBCTr and HBCTr group (P = .002 and P = .02, respectively) was decreased significantly compared with the CTR group. No significant changes found in the plasma levels of NADPH oxidase 5, thioredoxin-2, thioredoxin reductase-2, and resting blood pressure after GBCTr and HBCTr compared with the CTR group.

CONCLUSION

These results suggest that in hypertensive men, HBCTr equally to GBCTr improved functional fitness and body composition remarkably without necessarily reducing resting blood pressure. Therefore, they can be advisable substitutes for gaining health benefits.

Association Between Retinoid X Receptor Gene Variants and Dyslipidemia Risk in an Iranian Population

Background

Dyslipidemia is a complex trait that is influenced by various genetic and environmental factors. While the exact cause of dyslipidemia is still unknown, some studies have shown that genetic factors such as single nucleotide polymorphisms (SNPs) have been primarily associated with dyslipidemia. Based on the available data, it appears that retinoid X receptor (RXR) genes are jointly or separately associated with lipid homeostasis and that SNPs may affect RXR gene functions in lipid metabolism.

Methods

To study the possible role of the RXR genes in genetic susceptibility of dyslipidemia, three selected polymorphisms, rs3132294 located in RXRA (RXR-alpha) gene and rs2651860 and rs1128977 located in RXRG (RXR-gamma) gene, were investigated in 391 individuals with the use of tetra-primer amplification refractory mutation system polymerase chain reaction (T-ARMS PCR) method.

Results

For the rs3132294 SNP, the genotype frequencies in the case group were GG 58.5%, GA 33.2%, and AA 8.3%, and in the control group, they were GG 51.8%, GA 36.3%, and AA 11.9%. The genotype distribution of rs2651860 SNP in the case group were TT 43.2%, TG 52.1%, and GG 4.7%, and in the control group, they were TT 50.8%, TG 46.2%, and GG 3%. Genotype frequencies for the rs1128977 SNP in the case group were CC 34.7%, CT 47.6% and TT 17.7%, compared with CC 37.8%, CT 44.3%, and TT 17.9% in the control group. When the clinical characteristics of the case and control groups were stratified by allele carrier status for each SNP, the rs1128977 SNP was associated with increased levels of HDL-cholesterol, body mass index, waist circumference, and diastolic blood pressure (P< 0.05). In contrast, the alleles of the rs2651860 and rs3132294 SNP were not associated with an increased prevalence of dyslipidemia or clinical characteristics in the case group compared to the control group.

Conclusion

The present study suggests that rs1128977 SNP in the RXRG gene may affect the clinical characteristics in cases. However, further genetics association studies on large samples are required to validate our findings.

Twenty Years' Follow-up of a Family with Marfan Syndrome: A Case Series

Marfan syndrome is a rare connective tissue disorder manifesting with cardiovascular pathologies which are also the leading cause of death. Herein, we present the past 20 years follow up of a family with 17 members afflicted with Marfan syndrome. 3 members of the family were deceased and none were due to cardiovascular events. We assume to some extent traumas are a neglected cause for a part of mortality in Marfan syndrome.

Epidemiological, imaging, laboratory, and clinical characteristics and factors related to mortality in patients with COVID-19: a single-center study

Objectives

Coronavirus disease 2019 (COVID-19) is a novel pandemic. Considerable differences in disease severity and the mortality rate have been observed in different parts of the world. The present study investigated the characteristics and outcomes of patients hospitalized with COVID-19 in Iran.

Methods

We established a retrospective cohort to study hospitalized COVID-19 patients in Iran. Epidemiological, imaging, laboratory, and clinical characteristics and outcomes were recorded from medical documents. The chi-square test, t-test, and logistic regression models were used to analyze the data. A p<0.05 was considered to indicate statistical significance.

Results

In total, 364 cases (207 males and 157 females) were analyzed. The most common symptoms were cough, fever, and dyspnea. Multifocal bilateral ground-glass opacities with peripheral distribution were the predominant imaging finding. The mean age of patients was 54.28±18.81 years. The mean age of patients who died was 71.50±14.60 years. The mortality rate was 17.6%. The total proportion of patients with a comorbidity was 47.5%, and 84.4% of patients who died had a comorbidity. Sex, history of diabetes mellitus, and dyslipidemia were not significantly associated with mortality (p>0.05). However, mortality showed significant relationships with body mass index; age; history of hypertension, chronic kidney disease (CKD), ischemic heart disease, cerebrovascular accident (CVA), pulmonary disease, and cancer; and abnormal high-resolution computed tomography (HRCT) findings (p<0.05 for all). Cancer had the highest odds ratio.

Conclusion

Comorbidities (especially cancer, CKD, and CVA), severe obesity, old age, and abnormal HRCT findings affected the health outcomes of patients hospitalized with COVID-19.

Evaluation of LDL goal achievement in statin consumption, south east of Iran

Lipid goal achievement and statin consumption were estimated at extreme/very-high/high/moderate and low cardiovascular risk categories. In the cross-sectional study, 585 patients treated with statin therapy referring to the heart clinic of Birjand were recruited. Patients were classified and examined LDL-C values and the proportion reaching targets according to the American Association of Clinical Endocrinologists guideline. Three patterns of statin use (high/moderate/low-intensity statin therapy) in all patients were examined and attainments of LDL-C goal in cardiovascular risk groups have been demonstrated. Over half the populations (57.6%) were in the very-high CVD risk group. The results showed that the proportion of patients meeting total LDL-C goal values according to the guidelines was 43.4%. The frequency of patient had achievement LDL goal lower in high-intensity pattern (N = 13, 2.3%), compared with moderate (N = 496, 86.1%) and low-intensity patterns (N = 67, 11.6%). In general, LDL-C goal achievement was greatest with moderate-intensity statin use. LDL-C reduction after statin consumption was estimated about one-third of the studied population. It seems likely that the achievement of a therapeutic target for serum lipids such as LDL-C improved is far more cost-effective and would be able to reach the target LDL as well changing the type and intensity of statins.

One-year survival cohort of patients with reduced ejection fraction heart failure in Iranian population: A single center study

BACKGROUND

Cardiovascular diseases (CVDs) are one of the main concerns of health care systems. The aim of this study was to investigate the most important prognostic factors of heart failure (HF) and their survival outcomes in patients in Birjand, East of Iran.

METHODS

A total of 194 systolic HF patients hospitalized in Birjand Valiasr hospital were followed up for 12 months in 2016, and those with reduced left ventricle ejection fraction (LVEF < 50%) were included in this study. Kaplan-Meier and Cox proportional hazard analysis were used to determine the association of each factor with events.

RESULTS

The mean age of patients was 68.23 ± 13.40 (27-95) years, and 57.2% (111 out of 194) were women. Mean survival time was 294.7 ± 9.924 days. Pervious history of myocardial infarction (MI) [2.141 (1.101-4.161)] increased the risk of cardiovascular hospitalization. Elevated blood levels of potassium [2.264 (1.438-3.564)] was found to be a risk factor for all-cause and cardiovascular mortality. Moreover, there was a reverse relationship between body height [0.942 (0.888-0.999)] and cardiovascular death. Patients with opium addiction [4.049 (1.310-12.516)] are at a higher risk of cardiovascular mortality. Lower levels of LDL-C [0.977 (0.960-0.996)] and living in rural areas [3.052 (1.039-8.964)] increased all-cause mortality levels. Lack of pervious history of chronic obstructive pulmonary disease (COPD) decreased cardiovascular hospitalization [0.265 (0.062-1.122)].

CONCLUSION

In our study, serum potassium, LDL-C, and uric acid levels in patients with HF were identified as prognostic factors. The height of patients, which can be an indicator of the functional state of their respiratory system, and the history of COPD were also recognized as prognostic factors. Opium use and rural living were identified as social factors influencing patients' prognosis.

Rationale and Design of the Persian CardioVascular Disease Registry (PCVDR): Scale-Up of Persian Registry Of CardioVascular DiseasE (PROVE)

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.

Toxicity effects of Nerium oleander, basic and clinical evidence: A comprehensive review

Introduction:

Nerium oleander is a plant that is frequently grown in gardens and public areas. N. oleander is distributed originally in subtropical Asia but is now growing in many parts of the world, such as the United States, Australia, China, and Middle East countries. Pharmacological effects of plant including antinociceptive, anti-inflammatory, and anticancer activity were reported, but the potential toxic effects of all parts of the shrub either fresh or dried on animal and human body were documented.

Method:

The data of this review article were obtained from Medline/Pubmed, Scopusand Google Scholar databases in English until September 2019. To include all publications in this field, keywords such as N. oleander and toxicity were used.

Results:

The poisoning effects of plant or their active alkaloids induced infiltration of cells with hemorrhage and sever negative changes in the lung, induce lesions, and infiltration of inflammatory cells into the portal spaces with scattered necrosis of hepatocytes in the liver, cardiac toxicity of the plant in the heart were included, induced varying degrees of hemorrhage, myocardial degeneration, and necrosis. It also induced arrhythmia, sinus bradycardia, and prolonged P-R interval in electrocardiographic records.

Conclusions:

The toxic effects of N. oleander are mostly related to its inhibitory effects on the Na+-K+ ATPase pump in the cellular membrane. However, the exact molecular mechanism involved in the toxicity of N. oleander is not clear.

Effect of a Persian medicine preparation, Ma'aljobon, on constipation in patients with hypertension

Background:

Constipation is a common and prevalent digestive problem. Forcing and straining due to constipation may have a negative effect on some parts of the body, including the heart. The aim of the study was to evaluate the effect of Ma'aljobon (a kind of whey) on functional constipation in hypertensive patients.

Materials and Methods:

The present double-blind, placebo-controlled randomized clinical trial was a part of the study about the effect of Ma'aljobon on stage 1 hypertension, performed in 2017–2018. Hypertensive patients accompanying constipation were included in the study. Patients were randomly divided into two groups: Group A (n = 19) received 25 g of Ma'aljobon powder and Group B (n = 22) received 25 g of maltodextrin powder, twice a day for 6 weeks. The number and quality of defecation during a day were evaluated at baseline and at the end of the study within and between groups. Data were analyzed by SPSS software (version: 17) using Chi-square or Fisher's exact test. P <0.05 was considered as significant level.

Results:

Forty-one patients had inclusion criteria, of whom 34 patients completed the study (19 in Group A and 15 in Group B). The mean ± standard deviation age of patients was 53.86 ± 8.92 years (range: 34–80 years). Before intervention, there was no significant difference between the two groups with respect to constipation; however, after 6 weeks' treatment, the frequency of constipation was significantly different between groups (P < 0.001). At the end of 6^th week, constipation in the Group A was improved completely in terms of the number of defecation and stool consistency; but, in the Group B, eight (53.33%) patients still suffered from constipation (P < 0.001). No specific complications were reported in both groups.

Conclusion:

Ma'aljobon can improve constipation in hypertensive patients without any adverse effect.

Cardiac complications and iron overload in beta thalassemia major patients-a systematic review and meta-analysis

Despite the major improvement in therapeutic management of thalassemia major, iron overload is considered a challenging conundrum in these patients and heart disease still remains a major cause of morbidity and mortality in these patients. Therefore, this study aimed to investigate the prevalence of cardiac iron overload and cardiovascular complications in transfusion-dependent thalassemia patients in the worldwide. The following databases were searched: ISI/Web of Science, Embase, PubMed, Scopus, up to February 30, 2018. The quality of the studies was evaluated using the Joanna Briggs Institute Prevalence Critical Appraisal Tool. The random model based on Metaprop was used. One hundred forty-two studies were included. The total number of patients included was 26,893. The mean age of patients was 22.6 (SD = 1.7) years. Based on Metaprop, the overall prevalence of cardiac iron overload/myocardial sidoresis (T2* < 20 ms) and cardiac complications in thalassemia major patients in the worldwide was 25% (95% CI 22-28%) and 42% (95% CI 37-46%), respectively. The results of this study show that the prevalence of cardiac iron overload and cardiovascular complications in patients with thalassemia major is almost high. Therefore, iron chelation and careful monitoring of serum ferritin level will prevent the cardiac iron overload, and interval monitoring of patients with transfusion-dependent thalassemia (TDT) by echocardiography and electrocardiography will help with early detection of cardiovascular complications.

Comparison of atherogenic index and lipid profiles in candidates for coronary artery bypass graft surgery versus normal people

Information on incidence and risk factors of cardiovascular disease (CVD) is rare in the Middle East. This study aims to compare Iranian candidates for coronary artery bypass graft (CABG) surgery and healthy controls in terms of lipid profile, atherogenic index of plasma (AIP), and atherosclerosis index (ASTI). The individuals recruited in this study were 135 CVD patients before CABG surgery and 135 healthy subjects matching in age with the cases. Lipid profiles of the two groups were analyzed with a commercial kit. The AIP and ASTI indexes were calculated with related formula. The TC, TG, LDL-C and HDL-c parameters were dramatically changed (p<0.01) between study groups. AIP and ASTI indexes were significantly higher in patients than in healthy people (p=0.001). In individuals with CVD, it is suggested to measure these indexes in order for effective diagnosis before CABG surgery.

Cardiovascular Risk Factors and Atherogenic Indices in an Iranian Population: Birjand East of Iran

Introduction: The alteration in serum lipid profile; increase in total cholesterol (TC), triacylglycerol (TAG), and low-density lipoprotein cholesterol (LDL-C); and reduction in high-density lipoprotein cholesterol (HDL-C) are key factors in cardiovascular disease progression. The high prevalence and severity of cardiovascular diseases require new screening tools for better evaluation. Atherogenic index (AI) (LDL-C/HDL-C) and coronary risk index (CRI) (TC/HDL-C) can be strong markers for predicting the risk of atherosclerosis and coronary heart disease and disclose the presence of LDL or TAG in the serum of related patients. To implement this strategy, the AIs and CRIs in our population were assessed. In this study, a total of 5207 subjects were recruited and AIs and CRIs were calculated for all of them. According to our data, age, body mass index, sex, as well as CRI and AI had affirmative correlation with TC, LDL-C, TAG, systolic blood pressure, and diastolic blood pressure. By increasing these factors, AIs and CRIs were augmented. Moreover, in situations where all atherogenic parameters are normal, these parameters may be the alternative screening tool.

Prevalence and Determinants of Hypertension among Iranian Adults, Birjand, Iran

Background:

Hypertension (HTN) is a major cause of noncommunicable diseases. In this study, we report the prevalence rate of HTN in Birjand population.

Methods:

This cross-sectional study was conducted on 1286 individuals in Birjand in 2014. Individuals with systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure (DBP) ≥90 mmHg were considered as hypertensive. Data were analyzed using Chi-square test, independent t-test, and one-way ANOVA. P < 0.05 was considered as statistically significant.

Results:

Among the 1286 participants, 659 were women (51.2%). Prevalence of HTN was 20.1% (10.3% systolic HTN and 6.9% diastolic HTN). Prevalence self-reported HTN was 12.3%. SBP and DBP means were higher in men (P < 0.001). Mean scores of SBP and DBP increased by aging and body mass index (P < 0.001). Diabetic individuals had higher SBP scores (P < 0.001). Dyslipidemic patients had greater SBP and DBP (P < 0.001).

Conclusions:

Prevalence of HTN in our study is high. About one-fifth of the participants had HTN. In addition, BP is higher in men, elderly, and diabetic individual. Therefore, it is necessary to control BP regularly in different groups in society.

Comparison of Carotid Intima-media Thickness in Hypertensive Patients and Control Group

BACKGROUND

Hypertension (HTN), probably, is the most common public health problem among developed countries. Rapid diagnosis and effective treatment of HTN have not truly stopped the rapid rate of mortality and morbidity caused by HTN. Vascular wall changes are one of the most important and mortal complications of HTN. Ultrasonography was used for the evaluation of this vessel wall disorder by assessing the thickness of the intima and media layer.

OBJECTIVE

The objective of this study was to compare the Carotid intima Media Thickness (CIMT) in hypertensive patients and the control group.

METHODS

In a case-control study, 43 patients with documented primary HTN and 43 healthy subjects were assessed as control. Their HTN was controlled by the administration of drugs. The mean age was 53.9 years. The intima-media thickness (IMT) of internal and common carotid and outer vessel diameter were assessed by one radiologist.

RESULTS

CAIMT in all carotid arteries in the case group was more than that of the controls (P < 0.05). It was found that there was no difference between the length of having HTN and mean CAIMT in the hypertensive, except the right internal carotid (P = 0.024).

CONCLUSION

The present study found that the mean CAIMT of all carotid arteries in HTN was more than that of the controls. Moreover, the duration of the HTN can accelerate the atherosclerosis process in hypertensive patients.

The effect of a 10-week high-intensity interval training and ginger consumption on inflammatory indices contributing to atherosclerosis in overweight women

Background:

Most of the cardiovascular diseases can be prevented by doing regular physical exercises and using herbal supplements. The present study is aimed at assessing ginger supplement and high-intensity interval training (HIIT) on inflammatory indices contributing to atherosclerosis in overweight women.

Materials and Methods:

The present study is a randomized, experimental, and controlled one in which thirty healthy overweight women aged 20–30 years were randomly divided into three equal groups, namely, ginger, ginger + HIIT, and placebo + HIIT. The training groups performed high-intensity interval exercises (i.e. 40-m maximal shuttle run) for ten consecutive weeks. The supplement groups daily took 3 g of ginger pills and the third group took placebo.

Results:

Paired t-test revealed a significant decrease in the density of type 1 monocytes chemo tactic protein (MCP-1) in HIIT + ginger (P = 0.026) and HIIT + placebo (P = 0.001) groups. Besides, maximum aerobic capacity in the two training groups significantly increased P = 0.002 and P = 0.000, respectively. In spite of this, analysis of variance showed no significant differences in three groups regarding the three indices such as intercellular adhesion molecule-1 (ICAM-1) (P = 0.093), MCP-1(P = 0.075), and serum interleukin-10 (IL-10) (P = 0.164).

Conclusion:

A 10-week intensive interval exercise, by itself or together with ginger supplement, improved MCP-1 and maximum oxygen consumption in overweight women, without any significant effect on soluble ICAM-1 and IL-10. These findings indicate the relative and efficient role of HIIT in overweight women without the necessity to combine with ginger as an antioxidant/anti-inflammatory supplement.

The Effects of Statins on Pulmonary Artery Pressure in Patients with Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial

Objective:

Pulmonary hypertension is a serious complication in patients suffering from chronic obstructive pulmonary disease (COPD). The aim of this study is to investigate the effects of atorvastatin in reducing pulmonary arterial pressure in COPD patients.

Methods:

This double-blind, randomized trial was conducted on 42 known cases of COPD with systolic pulmonary arterial pressure of more than 25 mmHg. The patients were randomly assigned into two groups, 21 patients with atorvastatin treatment (40 mg/daily for 6 months) and 21 patients without receiving atorvastatin. All the patients participated voluntarily and provided written informed consent. The trial was registered in the Iranian Registry of Clinical Trials. Pulmonary pressure was also anticipated by Doppler echocardiography with peak pressure gradient of tricuspid regurgitation. Both groups were tested with echocardiography to measure systolic pulmonary pressure at baseline and posttreatment. Statistical analysis includes Chi-square, Student's t-test, and Wilcoxon test. P < 0.05 was considered statistically significant.

Findings:

The mean age was 65.8 ± 11.5 years for atorvastatin group and 63.7 ± 7.6 years for control group (P = 0.45). Baseline and posttreatment mean systolic pulmonary artery pressure (PAP) levels in the atorvastatin group were 48.9 ± 3.3 and 38.4 ± 1.9 mmHg, respectively (P = 0.007). In the control group, mean systolic PAP levels at baseline and 6 months later were 45.6 ± 3.1 and 38.9 ± 2.4 mmHg, respectively (P = 0.073). The patients treated with atorvastatin showed significant decrease in total cholesterol (P = 0.001) and low-density lipoprotein cholesterol (P = 0.008).

Conclusion:

A 40 mg dose of atorvastatin daily for 6 months may have beneficial effects in reducing PAP in patients with COPD. Further studies are necessary to find long-term effects of statins in COPD patients.

The Efficacy of Crocin of Saffron (Crocus sativus L.) on the Components of Metabolic Syndrome: A Randomized Controlled Clinical Trial

Objective:

Metabolic syndrome is a set of cardiac risk factors with increased risk of chronic diseases. The aim of this study is to evaluate the efficacy of crocin of saffron on metabolic syndrome.

Methods:

This double-blind, randomized clinical trial was conducted on metabolic syndrome patients who were randomly assigned to crocin of saffron or control (placebo) groups. The intervention group received 100 mg/day crocin tablets (a constituent of saffron) for 6 weeks. Then, the changes in metabolic syndrome component were compared between two groups. The trial was registered in the Iranian Registry of Clinical Trials. Data were entered to SPSS 15. Chi-square, Fisher's exact, paired t-test, and independent t-test were used to analyze data. P < 0.05 was defined as statistical significant level.

Findings:

Totally, 48 patients included in the trial (24 intervention and 24 placebo participants). There were significant reductions from baseline measurements in the levels of total cholesterol (P < 0.001) and triglyceride (P = 0.003) after the 6-week crocin administration. However, this decrease in lipid profile was not significant when compared with placebo group. There was no significant change in other laboratory values, blood pressure, and anthropometric measures.

Conclusion:

The present study indicated that the dose of about 100 mg crocin of saffron was well tolerated and has no complication for 6 weeks of oral administration. However, the dosage used in our study had no effect on metabolic syndrome. Further studies are required to assess this effect with the higher dosages of crocin as well as long time effects of its administration on metabolic syndrome patients.

A Systematic Review on the Prevalence of Acute Myocardial Infarction in Iran

In Iran, cardiovascular diseases are the most common causes of death. We aimed to perform a systematic review on the prevalence of acute myocardial infarction (AMI) in Iran based on Persian and English papers had been published from 1985 to 2015. Among 267 initially found articles, 142 were excluded; finally, a total number of 40 articles were found relevant which were reduced to 18. Smoking, hypertension, diabetes mellitus, and hypercholesterolemia were the most common risk factors for AMI. Premature MI prevalence was high in men, and smoking was the most common risk factor among young people. People in urban areas were more likely to experience AMI than rural people. The prevalence of AMI in Iran is high and has increased in recent years. Therefore, to restrain the rising trend of AMI, it is necessary to make the primary and secondary prevention efforts.

Prevalence of Dyslipidemia among Elementary School Children in Birjand, East of Iran, 2012

BACKGROUND

Various studies have indicated that dyslipidemia starts in childhood. There is a relationship between the concentration of blood lipids and atherosclerosis. In this study, we assessed the prevalence of dyslipidemia in elementary school children.

METHODS

This cross-sectional study was performed on 1,626 (882 girls and 744 boys) elementary school children aged between 6 and 11 years in Birjand in 2012. Samples were selected through multistage random sampling. The lipid profiles (i.e., cholesterol, triglyceride, high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C]) of the subjects were measured after 12 hours' fasting. The definition of dyslipidemia was based on the criteria of The American Children Academia in 2011.

RESULTS

Dyslipidemia (at least one abnormal level of a serum lipid) was detected in 31% of the children (31.3% of the girls vs. 30.6% of the boys). Total cholesterol was ≥ 200 mg/dL in 13.4% of the children, LDL-C was ≥ 130 mg/dL in 8.5%, HDL-C was < 40 mg/dL in 11.3%, and triglyceride was ≥ 130 mg/dL in 15.3%. The prevalence of hypertriglyceridemia was significantly higher in the females than in the males (16.3% in the girls vs. 13.8% in the boys; p value = 0.01) - while hypercholesterolemia (12.2% in the girls vs. 14.9% in the boys; p value = 0.16), high LDL-C (8.5% in the girls vs. 8.5% in the boys; p value = 0.05), and low HDL-C (12.7% in the girls vs. 9.5% in the boys; p value = 0.1) were not significantly different between the two sexes.

CONCLUSION

The prevalence of dyslipidemia was high in the school children in Birjand and, thus, requires preventive measures.

Prevalence of Metabolic Syndrome in Elementary School Children in East of Iran

Introduction: Metabolic Syndrome (MS) in children and adolescents is becoming a global public health concern. MS tracks into adulthood increasing the risk for type 2 diabetes mellitus and cardiovascular diseases. This study was designed to verify the rate of MS in elementary school students of Birjand, as a representative sample of Iranian children to verify the best preventive measures in this age group.

Methods: This descriptive-analytical, cross-sectional study was performed on 1425 elementary school children through multiple-cluster sampling in 2013. Height, weight, waist circumference and blood pressure of children were measured by standard methods. Blood glucose, triglycerides, cholesterol, High-density lipoprotein-cholesterol (HDL-C) and low-density lipoprotein-cholesterol (LDL-C) levels were also measured after 12 hours fasting. MS was defined according to the Adult Treatment Panel III (ATP-III) based on the National Cholesterol Education Program. Data were analyzed by SPSS using t test and chi-square test. Significance level was set at P < 0.05.

Results: The prevalence of MS was 5.3% which increased with age. 43.5% of the studied cases had one or more components of the MS. The most common components were hypertension, abdominal obesity, hypertriglyceridemia, low HDL-cholesterol and impaired fasting glucose, respectively. MS prevalence was 0.9% in normal weight, 11.3% in overweight and 36.2% in obese children.

Conclusion: Regarding the high prevalence of MS in elementary school children in our region, screening for obesity is recommended to prevent adulthood complications. Therapeutic lifestyle changes and maintenance of regular physical activity are the most important strategies for preventing childhood obesity.

Senile Calcification of the Trachea, Aortic Arch, and Mitral Annulus: An Incidental Finding on Chest X-Ray

A 94-year-old woman presented with dizziness and hypotension of 2 days' duration. She denied any syncope, presyncope, or angina. She had received a permanent pacemaker 12 years previously for the management of complete heart block (CHB), but she failed to program it. Twelve-lead electrocardiography revealed CHB with ventricular escape rhythm (40/min), so we inserted a temporary pacemaker. Anteroposterior chest X-ray showed trachea, aortic arch, and severe mitral valve calcification. Tracheal calcification is usually seen after 40 years old without clinical importance. However, it is seen in patients with renal failure, metastases, and prolonged use of warfarin as well as in pregnancy.(1) (-) (3).

Prevalence of high normal FBS and prediabetes among adolescents in Birjand, East of Iran, 2012

BACKGROUND AND OBJECTIVES

To determine the prevalence of impaired fasting glucose in adolescents in Birjand city in eastern Iran.

MATERIALS AND METHODS

This cross-sectional study was done on 2653 students aged 11-18 years selected through multi-stage stratified and random sampling. Fasting blood glucose (FBS) of these students was measured applying the enzymatic process. The obtained data were analyzed by means of SPSS software (V: 15) and statistical tests T and X2.

RESULTS

The mean age of individual was 14.5 ± 2 years. Mean FBS of the whole population was 89.8 ± 9.8 mg/dl, but it was significantly higher among boys than girls (P < 0.001). Out of the whole subjects (92.4%), 1,328 (95.1%) of the girls and 1,122 (89.3%) of the boys, FBS was less than 100 mg/dl among whom 64.4% had FBS above 86 mg/dl. In 200 subjects (7.5%) of whole population, FBS was 100-125 mg/dl; with that of the boys was 2.3 times than the girls revealing a prediabetes condition: OR = 2.3(CI: 1.7-3.2). Among the students, 3 (0.1%) had an FBS > 126 mg/dl. Mean blood glucose was significant regarding age and sex.

CONCLUSIONS

High prevalence of high FBS (within normal range) among adolescents is warning and requires special attention of health officials. Screening of children and adolescents in order to identify those at risk and plan for intervening is urgent to prevent type-2 diabetes epidemic and following cardiovascular complications in the Society.

The Prevalence of Diabetes and Prediabetes Among Elementary School Children in Birjand

Background:

Diabetes is associated with increased cardiovascular disease, mortality and morbidity.

Objectives:

The present study aimed at assessing fasting blood sugar (FBS) in elementary school students in Birjand, 2012.

Materials and Methods:

This cross-sectional and descriptive study was done on 1530 elementary school students who had been selected through multiple cluster sampling. FBS of these students was tested applying the enzymatic process. The obtained data was analyzed by means of SPSS software (v15) and statistical tests t and X².

Results:

In this study, 833 girls and 697 boys were evaluated. Mean FBS of the whole study population was 86.9 ± 8.8 mg/dL; FBS was higher in boys compared to girls. FBS of 1453 (95%) children was < 100 mg/dL, the mean being 85.8 ± 6.8 mg/dL. FBS of 698 (45.6%) students of the above population was 86-99 mg/dl. It was 100-125 mg/dL in 72 (4.7%) individuals. Five (0.3%) students had FBS >126 mg/dL. Mean FBS increased in proportion to age, which was statistically significant.

Conclusions:

Although the prevalence of diabetes is not considerable; however, based on the relatively high portion of those children with high degree of blood glucose in the range in which the risk of diabetes and prediabetes in the following years rises dramatically, the need for further care of health authorities, an extensive screening activity, and undertaking intervening measures to prevent the epidemic of diabetes and consequently cardiovascular disease is emphasized.

Lipid Profiles and Prevalence of Dyslipidemia in Eastern Iranian Adolescents, Birjand, 2012

BACKGROUND

Cardiovascular risk factors begin in childhood and adolescence. This study aimed at assessing serum lipids and prevalence of Dyslipidemia in 11-18 year old students of Birjand.

METHODS

The present cross-sectional, descriptive, and analytical study was done on 2,643 middle and high school students of Birjand aged 11-18 years (1,396 girls and 1,247 boys). Blood samples were collected for the measurement of blood lipids, including Cholesterol, Triglyceride, HDL, and LDL after a 12-hour fasting period. The defined borderline and abnormal values stated in 2011 by the American Academy of Child, was used.

RESULTS

According to our results, it is concluded that: (i) 34.3% (31.3% girls and 37.6% boys) of adolescents had at least one dyslipidemia. (ii) 24.7% of the individuals had HDL lower than 40, where 14% of them TG≥130, 6.1% of cases TC≥200, and 3.5% of cases LDL≥130. Lipid disorder within low HDL type and hypertriglyceridemia were significantly higher in boys (P<0.05) than girls. Hypercholesterolemia and hypertriglyceridemia in the age group of 11-14 years and low HDL in the age group of 15-18 years showed the highest values (P<0.05).

CONCLUSION

Adolescents of Birjand have high prevalence of dyslipidemia. Preventive measures are recommended to improve lifestyle, including healthy nutrition, encouraging adolescents to exercise, and more mobility.

A systematic review of the cardiotoxicity of methadone

Methadone is one of the most popular synthetic opioids in the world with some favorable properties making it useful both in the treatment of moderate to severe pain and for opioid addiction. Increased use of methadone has resulted in an increased prevalence of its toxicity, one aspect of which is cardiotoxicity. In this paper, we review the effects of methadone on the heart as well as cardiac concerns in some special situations such as pregnancy and childhood.

METHODS

We searched for the terms methadone, toxicity, poisoning, cardiotoxicity, heart, dysrhythmia, arrhythmia, QT interval prolongation, torsade de pointes, and Electrocardiogram (ECG) in bibliographical databases including TUMS digital library, PubMed, Scopus, and Google Scholar. This review includes relevant articles published between 2000 and 2013. The main cardiac effects of methadone include prolongation of QT interval and torsade de pointes. Other effects include changes in QT dispersion, pathological U waves, Taku-Tsubo syndrome (stress cardiomyopathy), Brugada-like syndrome, and coronary artery diseases. The aim of this paper is to inform physicians and health care staff about these adverse effects. Effectiveness of methadone in the treatment of pain and addiction should be weighed against these adverse effects and physicians should consider the ways to lessen such undesirable effects. This article presents some recommendations to prevent heart toxicity in methadone users.

The relationship between serum lipids and obesity among elementary school in Birjand: a case control study

BACKGROUND

Childhood obesity could induce some risk factors for cardiovascular disease (CVD) including serum lipid abnormalities, hypertension, and atherosclerosis. The present study aimed to comparison the lipid profile in normal children with cases having overweight, obesity and central obesity.

METHODS

In this case control study, which was conducted 2013, serum lipids for three groups of children including cases with overweight (Body mass index (BMI): 85-95th percentiles to age and sex and waist circumference (WC) <90th percentile to age and sex = Case group1), central obesity without general obesity (BMI <85th percentiles and WC ≥ percentile 90 = Case group 2) and central obesity with general obesity (BMI ≥95th percentile and WC ≥ percentile 90 = Case group 3) were compared with control group (BMI < 85th percentiles WC <90th percentile). Data were analyzed using software SPSS-16 by chi-square and ANOVA tests at significance level α=0.05.

RESULTS

Each group consisted of 100 individuals. The highest mean of serum lipids and the highest extent of dyslipidemia existed in the children having central obesity along with general obesity. So that 49%, 28%, and 38% students of this group show hypertriglyceridemia, hypercholesterolemia, and low high-density lipoprotein cholesterol (HDL-C). Odd ratio of hypertriglyceridemia, hypercholesterolemia and low HDL-c, in children with at least one abnormal index (BMI and /or WC) compared with control group were 3.73 (95% CI: 1.98, 6.99), 1.37 (95% CI: 1.71, 2.65) and 2.98 (95% CI: 1.51, 5.87), respectively.

CONCLUSIONS

With regard to the relationship between central obesity and adverse changes in lipid profiles, the screening children for central obesity to prevention of cardiovascular disease are recommended.
