The frequency of arrhythmias in COVID-19 patients, a study in the Shahid Mostafa Khomeini Hospital of Ilam from March to August 2020

Introduction: Cardiac arrhythmias are important causes of death among populations and always responsible for a high percentage of mortality in hospitalized patients. The aim of this study was to evaluate the frequency of arrhythmias in COVID-19 patients in the Shahid Mostafa Khomeini Hospital of Ilam from March to August 2020. Materials and Methods: In this descriptive-analytical study, all the COVID-19 patients with a cardiac condition admitted to the intensive care unit were enrolled by census. Electrocardiography (ECG) and Holter monitoring were used to diagnose arrhythmias. Data analysis was performed in Microsoft Excel using descriptive statistics (frequency and percentage). Results: The total number of eligible patients was 45, of whom 26 (57.8) were men, and 19 (42.2) were women. The mortality rate of arrhythmias among COVID-19 patients was 17.77 (8 out of 45 patients), and the recovery rate was 82.13 (37 out of 45 patients). Conclusion: Tachycardia and the lack of response to heart rate reducing drug be observed in patients with COVID-19.Owing to an overlap between these symptoms and those of heart diseases, there is a need to further evaluate patients with arrhythmias. Although arrhythmias are not common in COVID-19 patients, they can be fatal and inflict a high mortality rate, which can be prevented by early detection

Comparison religious attitudes and aggressiveness in the satellite users and normal

In recent years is one of the factors on various aspects of life of the population, growth and technological progress and the people of them in different ways. One of the most important of these factors is satellites and satellite programs. The present method of this study is descriptive study ex post facto. Population of the study all of satellite users and normal people were city of Ilam. For study 100 patients (50 user of satellite and 50 normal subjects) as available for example in the study participated. To collect data of religiosity of muslims measures questionnaire and aggressiveness of Ahvaz was used. Data t-test for independent groups and using statistical software SPSS were analyzed. Results showed that the total score of religious attitudes and its dimensions (beliefs, experimental results and ceremonial) in satellite user groups and normal there is a significant difference. Also results showed that aggressiveness of satellite user groups and normal also there is a significant difference in such a way that the average of aggressiveness in the of satellite users more than ordinary people. According to the results of this study, experts and activists in the field of health should be the role of new technologies, cultural changes as well as the impact on adolescent risk behaviors the more they studied. © Medwell Journals, 2016

Dosimetry of gamma chamber blood irradiator using PAGAT gel dosimeter and monte carlo simulations

Currently, the use of blood irradiation for inactivating pathogenic microbes in infected blood products and preventing graft-versus-host disease (GVHD) in immune suppressed patients is greater than ever before. In these systems, dose distribution and uniformity are two important concepts that should be checked. In this study, dosimetry of the gamma chamber blood irradiator model Gammacell 3000 Elan was performed by several dosimeter methods including thermoluminescence dosimeters (TLD), PAGAT gel dosimetry, and Monte Carlo simulations using MCNP4C code. The gel dosimeter was put inside a glass phantom and the TL dosimeters were placed on its surface, and the phantom was then irradiated for 5 min and 27 sec. The dose values at each point inside the vials were obtained from the magnetic resonance imaging of the phantom. For Monte Carlo simulations, all components of the irradiator were simulated and the dose values in a fine cubical lattice were calculated using tally F6. This study shows that PAGAT gel dosimetry results are in close agreement with the results of TL dosimetry, Monte Carlo simulations, and the results given by the vendor, and the percentage difference between the different methods is less than 4% at different points inside the phantom. According to the results obtained in this study, PAGAT gel dosimetry is a reliable method for dosimetry of the blood irradiator. The major advantage of this kind of dosimetry is that it is capable of 3D dose calculation

Determination the Amount of Illegal Furazolidone Residues in Broilers in Ahvaz Abattoir by HPLC Method

Background & aim: due to the risks to human health, particularly in terms of carcinogenicity, the application of Furazolidone in animals which their products are consumed by human population is strongly prohibited. The purpose of this study was to determine the amount of unauthorized furazolidone in broiler chickens slaughtered in Ahvaz by using HPLC. Methods: In the present cross-sectional study which was conducted within six months, 100 broiler carcasses were randomly collected from Ahvaz slaughterhouses. Then by using ice, the carcasses were transported to the laboratory in less than 24 hours inorder to illicit the amount of furazolidone drug by the HPLC method. After extraction and degrading processes, using Ethyl-acetate and related protocols for isolation of Furazolidone from muscles, and also calibrating HPLC system to obtain standard curves, the amount of 20 microliters of each sample was injected to the HPLC device and the amounts of Furazolidone were determined in the mixture of pectoral and femoral muscles. Finally the obtained results were statistically analysed by using one sample t-test in the SPSS software. Results: The mean Furazolidone concentration in the mixture of femoral and thorasic muscles was 28.15±2.37 mg/kg. Thirty-nine percent of the samples were positive for containing illegal Furazolidone residue. Conclusion: According to the results of the current study, more attention is seriously recommended by authorized responsibilities to prevent the antibiotic residues such as furazolidone in poultry meat

Calculation of dose distribution in compressible breast tissues using finite element modeling, Monte Carlo simulation and thermoluminescence dosimeters

Compression is a technique to immobilize the target or improve the dose distribution within the treatment volume during different irradiation techniques such as AccuBoost (R) brachytherapy. However, there is no systematic method for determination of dose distribution for uncompressed tissue after irradiation under compression. In this study, the mechanical behavior of breast tissue between compressed and uncompressed states was investigated. With that, a novel method was developed to determine the dose distribution in uncompressed tissue after irradiation of compressed breast tissue. Dosimetry was performed using two different methods, namely, Monte Carlo simulations using the MCNP5 code and measurements using thermoluminescent dosimeters (TLD). The displacement of the breast elements was simulated using a finite element model and calculated using ABAQUS software. From these results,the 3D dose distribution in uncompressed tissue was determined. The geometry of the model was constructed from magnetic resonance images of six different women volunteers. The mechanical properties were modeled by using the Mooney-Rivlin hyperelastic material model. Experimental dosimetry was performed by placing the TLD chips into the polyvinyl alcohol breast equivalent phantom. The results determined that the nodal displacements, due to the gravitational force and the 60 Newton compression forces (with 43% contraction in the loading direction and 37% expansion in the orthogonal direction) were determined. Finally, a comparison of the experimental data and the simulated data showed agreement within 11.5% +/- 5.9%

Clinical features of novel coronavirus 2019-infected cases with pre-existing cardiovascular disease, disaggregated by gender

Objectives: This study was conducted to evaluate the clinical features of 68 coronavirus 2019-infected cardiac cases on gender basis. Methodology: Clinical, laboratory and electrocardiographic data of 68 COVID-19 patients with pre-existing cardiovascular diseases, analyzed and compared by gender-wise. Results: Dry cough (78 of male, 80 females) and fever (62 of male, 75 females) were the most common symptoms. Out of these 97 of them needed O2 supplementation. O2 saturation in patients with O2 therapy was 85; 31 of men and 11 of women experienced intubation. The most common laboratory abnormalities, were neutrophilia, leukocytosis, lymphopenia, thrombocytopenia, decreased hemoglobin level, increased creatinine and urea, in men and women. Troponin level was different between male and female. Pneumonia was found in 86-87 patients. Approximately, Males and female, respectively53.10 and 52.8, shown sinus tachycardia (ST arrythmia). PVC arrythmia was found in 2.9 of total patients. BBB arrythmia was found in 31.20 of males vs. 11.10 of females. The mean systole/diastole blood pressures respectively were 130±4/79.7 ±2 in males and 134±4/81±3 in females. Heart axis changes was identified in 43.8 and 27.8 of males and females respectively. Conclusion: Severity of symptoms and outcomes of COVID-19 in cardiac patients showed some differences between men and women which could be associated with differences in immune responses, respiratory tract properties, renin angiotensin system, sex hormones and lifestyle. However, more studies to categorize gender differences are required. © 2017 Pakistan Cardiac Society. All Rights Reserved
