Volume 60, Issue 3 (14 2002)
Abstract

Introduction: Ischemic heart disease is the most common cause of mortality in developed countries. CABG (Coronary Artery Bypass Graft) is one of the therapeutic methods in ischemic heart disease.

Methods and Materials: Considering the increased incidence of coronary artery disease in Iran, and with increased rate of CABG, we performed a cross sectioned study (1996-1999). In 635 patients 467 male (73.5 percent), 168 female (26.5 percent) about risk factors of mortality after CABG in cardiac surgery department "Imam Khomeini hospital. 20 risk factors were included in our study: age, gender, smoking, family history, diabetes mellitus, morbid obesity, hypercholesterolemia, hypertension, palpitation, renal failure COPD, (chronic obstructive pulmonary disease), history of myocardial infarction, CHF, angina, cerebral vascular disease, pace maker, Ejection fraction<40 percent, history of PTCA, history of CPR, and coronary endarterectomy.

Results: Cigarette smoking (P=0.40), CHF in female (P=0.003). Endarterectomy in both gender (P=0.0001). Pace maker in both gender (P=0.00006), palpitation in both gender (P=0.0001). CPR in both gender (P=0.0000001), were associated with increased risk of mortality after CABG.

Conclusion: We found that, endarterctomy, cigarette smoking, CHF. Pace maker, CPR, and palpitation are important risk factors for mortality after CABG.

Volume 64, Issue 4 (1 2006)
Abstract

Background: Acute bacterial sinusitis is one of the most common causes for antibacterial treatment. Oral Penbactam (ampicillin- sulbactum or Sultamicillin) is a broad spectrum antibiotic and it has no significant side effect. To our knowledge, this is the first study in Iran in which, oral Penbactam has been prescribed for patients with acute bacterial sinusitis.

Methods: A randomized clinical trial was performed on 44 outpatients diagnosed with acute bacterial sinusitis in Amir- Aalam Hospital from March 2003-2004 to August 2004. Patients were randomized in 2 group: 23 to oral Penbactam (375 mg twice daily), and 21 to oral Co-amoxicolav (625 mg three times daily). Duration of treatment was 10 days for both groups.

Results: Both groups showed a significant clinical improvement after 10 days of treatment. In the Penbactam group, 19 of 23 (86.36%) and in the Co-amoxicolav group ,18 of 21 (85.71%) showed clinical improvement. In the Penbactam group, one patient (4.3 %) developed diarrhea and the medication was discontinued.

Conclusion: Oral Penbactam is an effective and safe antibiotic in the treatment of acute bacterial sinusitis and could be used as an alternative medication for acute bacterial sinusitis.

Volume 70, Issue 4 (5 2012)
Abstract

Background: Various therapeutic options such as calcitonin have been suggested for patients with low bone density, despite uncertain efficacy in most patients. C-telopeptide of type I collagen (CTX) is a new bone marker used for the assessment of bone resorption. The aim of this study was to evaluate the therapeutic effects of nasal spray calcitonin in women with osteopenia via serum CTX and other laboratory tests.

Methods: We conducted a self controlled clinical trial in 2009 on 105 women of menopausal age diagnosed in Baqiyatallah Hospital Clinic with osteopenia based on a bone mineral density score of 1.5 SD lower than peak bone mass. The patients were assigned to receive nasal spray calcitonin (200 IU/day), calcium (1000 mg/day) and Vit-D (400 IU/day) for 6 months. Serum CTX and other laboratory parameters were measured before and after the treatment. The data were analyzed by SPSS, version 17, using t-tests and a P<0.05 was considered statistically significant.

Results: Fifty-two patients completed the study and the mean CTX level decreased significantly from 3.10±2.03 to 2.61±1.82 pmol/lit (P<0.001), but total serum levels of PTH, Ca, AST, ALT and Alkaline Ph decreased insignificantly.

Conclusion: It seems that nasal spray of calcitonin is significantly effective in preventing disease progression and treatment of low bone density by inhibiting bone tissue resorption indicated by CTX although further studies with larger samples sizes and inclusion of control groups are warranted.

Volume 73, Issue 2 (May 2015)
Abstract
Background: Personal characteristics such as gender, ethnicity, disability, age, goals and personal expectations and academic variables such as the number of classes and grades are among the factors that could have an important role in the development of student satisfaction. Besides these factors, the relationship between emotional intelligence (EI) and academic satisfaction has received little attention. Methods: This descriptive cross-sectional study was done in Tehran University of Medical Sciences, Tehran, 2013. Cluster sampling was applied in this study. First, faculties randomly selected from Tehran University of Medical Sciences then randomly selected classes from the faculties. Self-report and Barr-On's emotional Intelligence questionnaires were used to collect data and measuring the variables of educational satisfaction. Questionnaires were completed by students. Overall reliability test using Cronbach's alpha coefficient was 0.73. The cut-off point of questionnaires was considered 70. This means that scores below 70 points showed the low level of satisfaction and scores more than 70 points were considered as a high level of satisfaction. Results: One hundred sixty eight students participated in the study. Average emotional intelligence was 3.25±0.45, the scale of consciousness 3.44±0.59, the self-control scale 3.90±0.59, scale spontaneous 3.17±0.46, Social skills 3.30±0.59, social consciousness 3.24±0.67, satisfactory academic 96.55±14.66 respectively. There was a significant relationship between self-consciousness and educational satisfaction (P=0.002) but self-control variable did not significantly correlated with educational satisfaction (P=0.249). The results showed that emotional intelligence on academic satisfaction can be explained. A change in the variance in one unit emotional intelligence was as much as five unit of the variance student satisfaction in based on standardized beta coefficient. There is a positive and direct relationship between them. Conclusion: The promotion of education satisfaction will increase indirectly possibility of job satisfaction in students in the future. Our results showed self-awareness and motivation skills in students increase their educational satisfaction.

Volume 78, Issue 2 (May 2020)
Abstract
Background: The supratrochlear foramen (STF) is an important and relatively common anatomic variation in the lower end of the humerus in humans. In recent years it has become clear that STF should be emphasized because anatomical knowledge of STF is useful for anatomists, anthropologists, orthopedic surgeons, and radiologists. The anatomical structure of the humerus may play an important role in the intramedullary fixation thereby stressing the need of prior anatomical knowledge and preoperative planning in the presence of variations like STF in the distal end of the humerus. This study focuses on STF in the distal of the humerus bone and as well as the intertubercular sulcus (ITS) in the Iranian population.
Methods: This study was performed on 57 adult human humeral bones regardless of their gender at Arak University of Medical Sciences in Iran that it was done from October 2014 to March 2015. A total of 57 dried humerus (27 right side and 30 left side) were examined to determine the presence of supratrochlear foramen and septum. They were free from any pathological changes and fractures. The STF was analyzed for morphology and morphometric correlation.
Results: STF was found in only four cases (6.8%) of the humerus bones, two cases (3.4%) on the left and two cases (3.4%) on the right. The shape of the STF was oval, round and triangular. The mean STF transverse diameter in the right bones was 2.60±2.68 mm and in the left bones 0.57±0.31 mm and the mean vertical STF diameter in the right and left bones were 1.75±1.76 mm and 0.55±0.07 mm, respectively.
Conclusion: There was no significant difference in the shape of the STF and its number in the right and left bones. Twenty-seven bones (47%) out of 53 bones without supratrochlear foramen (STF) had septum.

Volume 79, Issue 11 (February 2022)
Abstract
Background: Breast cancer is the second leading cause of cancer death in women, after lung cancer. Due to the importance of predicting this disease, the use of data mining methods in medical research is more significant than before. Data mining algorithms can be a great help in preventing the development of lymphedema in patients. The aim Of this study was to create a diagnosis system that can predict the probability of lymphedema in breast cancer patients.
Methods: In the present study, the factors of lymphedema in 1117 patients with breast cancer have been collected. The likelihood of developing lymphedema is predicted using ensemble learning via 5 heterogeneous classification algorithms, feature selection and the genetic algorithm (The Two-layer Ensemble Feature Selection method). After collecting the data of patients with breast cancer from 2009 to 2018, and data preprocessing using the optimized ensemble learning algorithm and feature selection, we will examine the likelihood of developing lymphedema for the new patient. Finally, the factors affecting the disease have been extracted. Excluding the time of collecting statistical data, the period of the study was from September 2019 to February 2021. This study is performed at Seyed Khandan Rehabilitation Center, Tehran, Iran.
Results: The results of algorithms showed that the accuracy of the ensemble learning method with selected classification algorithms (SVM with RBF kernel) is 87% and the accuracy of the ensemble learning with feature selection method is 90%. According to the final evaluation of the proposed method, the most effective risk factors for lymphedema have been extracted.
Conclusion: Unfortunately, treatment and diagnosis are not without complications, and one of the most important of these complications in breast cancer is lymphedema in the upper extremities, which can affect the quality of life in patients. It is essential to have a method that can accurately suggest to a specialist whether a new patient will develop lymphedema in the future or how likely it is to develop it, using patient’s own clinical and demographic characteristics.

Abstract
Background: This study aimed to assess the efficacy and safety of the oral use of ibuprofen suspension in various doses in the treatment of PDA (Patent ductus arteriosus) in mature babies. Mature babies (37-42 weeks) aged more than 3 days who had been diagnosed with PDA were involved in this study. For the measurement of the ratio of left atrial to aortic root diameters (La/Ao) Color, pressure gradient and the internal ductal diameter, Doppler echocardiography (ECHO) was performed. This clinical trial was performed on 60 infants born born between August 2013 to August 2015.
Methods: This clinical trial study was performed on 60 infants were randomly born between August 2013 to August 2015 which Randomly divided into two groups: The first group, received oral ibuprofen in three doses (5, 5, 10 mg/kg at 24-hour intervals) and the second group received an early dose of OIS, in two doses of 10 mg/kg after 24 and 48 hours (totally 20 mg/kg). A follow-up ECHO was performed 48 hours and 2 weeks after treatment by the same pediatric cardiologist who was not aware of the study groups. Evaluation of changes in platelet count, blood urea nitrogen, creatinine and complications of thrombocytopenia, evaluation of elevated serum creatinine, and complications of gastrointestinal bleeding were compared between the two groups using statistical analysis.
Results: Seventy-three percent (73%) patients in the first group and seventy-six (76%) patients in the second group had successful PDA closure in the first 48 hrs. No statistically significant difference between the two groups (P=0.0001) was obtained and the highest response time was observed in the first 48 hours of treatment. After 2 weeks, the PDA closure in both groups was completely successful (100%). No specific side effects were observed between the two groups.
Conclusion: We conclude that higher doses of ibuprofen (20 and 2×510 mg/kg) do not show better results for PDA closure without renal or gastrointestinal complications.
