Abstract

Background and Aim: In a severely inflationary environment with unemployment, social problems increase and, therefore, high health care expenses are imposed on the society.

Materials and Methods: This was a correlational study. Panel data model and EVeiws 6 software were used in this study. The data were collected from the World Bank website. The required pre-tests, including F-Limer and Hauseman tests, were given to check the appropriateness of data and to determine a appropriate model. Following the pre-tests, the results were estimated in the form of a regression model.

Results: The results indicated that F-test and t-statistic were significant, and that R2 statistic was high. In the three models, R2 was 99%, 99% and 98%, respectively. Moreover, it can be said that employment is positively related with life expectancy, but negatively related with infant mortality and total fertility rate. Also, inflation is negatively related with life expectancy, but positively related with infant mortality, and total fertility rate. Finally, Gross Domestic Product (GDP) is negatively related with total fertility rate and life expectancy, but has no meaningful relationship with infant mortality (p = 0.31).

Conclusion: Employment, inflation and GDP are the variables that have the greatest impact on health indicators. however, life expectancy is more sensitive to explanatory variables.

Abstract

Background and Aim: Chronic lymphocytic leukemia (CLL) is a lymphoprolifrative disorder, which is very heterogeneous in prognosis. Therefore, the analysis of the prognostic factors should be very helpful in diagnosing patients with a poor prognosis. The aim of this study was to determine the relationship between circulating Endothelial cells number with VWF levels along with the other hematological findings in CLL.

Materials and Methods: Peripheral blood samples were obtained from 30 CLL patients admitted to the hematology department of Firozgar hospital and 30 healthy subjects. The levels of CEC were measured by the presence of CD34 and VWF markers, and absence of CD45 marker, using flow cytometry. VWF levels was evaluated by ELISA.

Results: The CEC levels were significantly higher in blood of the CLL patients (0.64%), when compared to the controls (0.12%, P=0.002). The levels of plasma VWF were higher among high grade patients, when compared to controls and patients in lower grades. There was a negative correlation between CEC levels, and Hb concentration in the patients group (r=-0.47, P=0.01).

Conclusion: Although the levels of both CEC count and plasma VWF in patient with high grade CLL were increased when compared to patients with low grade, there was no significant correlation between these two parameters.

Abstract

Background and Aim: Inclusive implementation of Electronic Medical Records (EMR) is more serious because of physicians’ perception. This study was carried out to identify the effects of organizational contextual factors on physicians’ perception regarding EMR’s adoption in 2013 (The merger of Tehran University and Iran). 
Materials and Methods: This was a descriptive, analytical and cross- sectional study in which a sample of 270 physicians working in hospitals affiliated to Tehran University of Medical Sciences was selected. Physicians’ perception toward adoption of EMR has been assessed by Technology Acceptance Model or TAM questionnaire and organizational context variables. Collected data were analyzed by SPSS. The study model was tested by Structural Equation Modeling (SEM) and represented by AMOS. 
Results: The findings showed that perceived usefulness (PU), perceived ease of use (PEOU), management support, physicians’ involvement, physicians’ autonomy, and physician- patient relationship have direct and significant effect on physicians’ attitudes toward EMR adoption. However, training has no significant effect on TAM variables. Moreover, the results showed authorizing proposed conceptual path model explained about 56 percent of the variance of EMR adoption.
Conclusion: The present study revealed that organizational context factors had significant effect on physicians’ attitude toward EMRs’ adoption. The study clearly identified six relevant factors that affected physicians’ perception regarding EMR adoption. These factors should be considered when comprehensive implementation is pursued.

Abstract

Background and Aim: Employees’ silence is common in organizations, and is mostly neglected. Employees are indifferent towards their supervisors, work quality and organization. Organizational justice is a factor that can diminish employees' silence. The aim of this study was to determine the relationship between organizational justice and headquarters employees' silence in Kerman University of Medical Sciences (KMU).
Materials and Methods: This study was a descriptive-correlational and cross-sectional research. The population included all 400 employees at KMU headquarters, among whom 147 members were selected as the sample using Cochran’s formula. In this study, two questionnaires were used: organizational justice questionnaire with a reliability of 0.91 and employees’ silence questionnaire with a reliability of 0.92. For data analysis, Pearson and Spearman correlation, regression testing, by SPSS software were used.
Results: The findings showed that there was an inverse relationship between organizational, distributive, procedural, and interactional justice with employees' silence in Kerman University of Medical Sciences. The regression findings showed that the variable “distributive justice” had the strongest negative effect on employees' silence.  
Conclusion: Encouraging employees to provide positive ideas, identify the existing problems, and reduce undesirable behavior like employees' silence can make employees operate more efficiently. Organizational justice is based on fair treatment, and it determines the employees’ reaction to organizational decisions. Therefore, it can partly remove problems and lead to the decline of employees' silence.

Abstract

Background and Aim: Cancer disease is one of the main problems of Iranian health system. It is after Cardiovascular diseases and accidents, the third leading cause of death in Iran. In many countries, differences in socio-economic status have been linked with the incidence of disease, death and in general, health inequalities. The aim of this study is to determine the socioeconomic factors associated with the incidence of leukemia in Iran.
Materials and Methods: The present descriptive-analytical study was done with panel data modeling, including information related to 30 provinces of Iran from 2004 to 2009. Socioeconomic data were collected from provincial statistical yearbooks and data on age-standardized incidence rate (ASIR) of leukemia cancer per 100,000 populations were obtained from published reports by Iran Cancer Registry. 
Results: The results showed that the leukemia incidence in men and in women during the period under review has been upward. The highest and lowest incidence of leukemia was in Yazd and Sistan provinces, respectively. Direct relationship between unemployment rate, urbanization ratio, and human development index with cancer incidence rate was evident in this study.
Conclusion: The increase of leukemia cancer in Iran has been confirmed by the current study. Leukemia cancer was significantly higher among provinces with higher socioeconomic status. This should be considered for planning support.

Abstract

Background and Aim: Brain tumors have remained as a significant cause of morbidity and mortality and are often refractory to treatment. The grading of brain tumor has an important implication in clinical management. Currently, magnetic resonance spectroscopy (MRS) is an important dimension in evaluating metabolites and grading brain tumors. The aim of this study is to evaluate metabolites in brain tumors and grading brain gliomas using HMRS (proton magnetic resonance spectroscopy).

Materials and Methods: Studies were performed using single voxel MRS, at a field strength of 3Tesla and pulse sequence using point resolved single volume spectroscopy (PRESS) with repetition time (TR) 1000-6000ms and echo time (TE) 36-136ms, and distinguished metabolites including Choline (Cho), Creatin (Cr), and N-acetyl aspartate (NAA) were detected.

Results: Thirty-seven cases (17 males and 20 females) had data which passed quality control. The patients’ age ranged from 7 to 81 years with a mean of 41.46±2.78. MRS data were processed using SYNGO software in terms of mean spectra and metabolite concentrations which were compared using minitab and SPSS. Significant differences were found in concentrations of key metabolites, and Cho/NAA and Cho/Cr ratios using t-test with a significance level (α≤0.05). In the assessment of age rate and tumor grading, the malignancies of brain tumors did not correlate with patients’ age and sex.

Conclusion: MRS can detect subtle differences between low-grade brain tumors in children and should form part of the clinical assessment of these tumors.

Abstract

Background and Aim: Cosmetic surgery rhinoplasty, has dramatically been increased during the last two decades. This study aims to explore its effects on the quality of life of individuals gone under the surgery.

Materials and Methods: This was a descriptive and analytical study which was performed as a cross-sectional study. From all plastic surgery clinics in Teheran, 25 clinics were selected randomly as the site of study. In the next step 110 patients undergone rhinoplasty were selected randomly from these clinics. Collected data was analyzed by Spss17.

Results: Findings revealed that, the mean score of quality of life before and after surgery was statistically significant. While mean score of general benefits increased the score of social support and physical health was decreased after the surgery. The most motivating factors for surgery were external factors. In addition there was a positive correlation between quality of life and the time of interview. Also the mean cost of surgery was increased.

Conclusion: Overall quality of life among study population was decreased. It could be because of unnecessary surgeries, medical errors, and etc. The reduction for social support may be resulted from unacceptable consequences of rhinoplasty particularly in terms of appearance. Physical health of respondents was negatively affected by rhinoplastiy surgery. Malfunctions of upper respiratory system after rhinoplastiy surgery is known as the main reason for it. Correlations between the times of surgery and interview suggest a long term assessment of impacts of such surgeries.
