Abstract
|
Background: Schizophrenia (SC) and bipolar disorder (BD) are two chronic psychiatric illnesses with worldwide distribution. People could be involved at any age, particularly in early adolescence. Main symptoms of SC are non- affective symptoms such as auditory hallucination and illogical thinking. In contrast, BD represents affective symptoms such as depression and mania. Although the main cause of these mood disorders has been remained elusive, there are some potential contributing factors that could be considered in the pathogenesis of mentioned illnesses including, genetic and environmental factors. Cytomegalovirus (CMV) is one of the probable contributing factors in SC and BD. CMV is a prototype of herpesviridae family which may infect different cell types such as endothelial and differentiated hematopoietic cells. CMV infections in immunocompromised patients as well as congenitally infected children represent CNS complication such as microcephaly and hearing loss. This virus has capability to impair the limbic structures in brain. Methods: This descriptive study was designed to evaluate the role of CMV in these illnesses. We investigated the level of serum IgG antibody and the presence of CMV DNA in serum and peripheral blood mononuclear cells (PBMCs) samples of 46 SC and BD patients admitted to Iran Psychiatry Hospital Tehran, Iran from 2014 to 2015 as well as 46 healthy control groups at Tehran University of Medical Sciences. First, the level of CMV IgG antibody was evaluated in serum samples, by enzyme-linked immunosorbent assay (ELISA). Then, DNA extraction conducted by using the high pure viral nucleic acid kit (Roche, Germany). Serologically positive sera along with PBMC samples were tested by Real-time PCR, to investigate the presence of CMV DNA. Results: Results indicated higher levels of CMV IgG antibody in psychiatric patients, compared with a healthy control group. Afterward, we did not observe the presence of CMV DNA in either case or control groups. Conclusion: According to the CNS impairment mediated by CMV infection, this virus has been supposed to play an important role in pathogenesis of mental disorders such as SC and BD. We suggest further investigation to be conducted, particularly on other samples such as cerebrospinal fluid. |

Abstract
Background: Postoperative pain is one of the most common complications following laparoscopic cholecystectomy. Because the majority of the analgesic drugs including opioids and nonsteroidal anti-inflammatory drugs have many side effects, using drugs with lesser side effects is beneficial. The aim of this study was to evaluate the effect of N-acetylcysteine on the pain after laparoscopic cholecystectomy.
Methods: In a randomized clinical trial, in two university-affiliated teaching hospitals in Babol City (Shahid Beheshti and Shahid Yahyanezhad Hospitals), Iran, from August 2015 to March 2015, a total number of 38 patients with age of 20-50 years, who were candidates for laparoscopic cholecystectomy with American Society of Anesthesiologists Class-I were chosen and randomly assigned into two groups. The night before operation, 1200 mg oral N-acetylcysteine is given to intervention group. Also, they received 600 mg IV N-acetylcysteine in the morning before operation. In the control group, two vitamin C effervescent tablets as placebo were given at night before operation and 3 ml sterile water as placebo was injected in the morning of operation. Amount of pethidine consumption and the changes in hemodynamic in two groups was recorded and analyzed at 24 hours after operation.
|
Results: The average of patients age was not significant different between two groups (P=0.23). Average of pain score in placebo group was 3.5 and in N-acetylcysteine group was 2.7 that it was not significant difference between two groups (P=0.06). Average of pethidine consumption in placebo group was 52 mg and in N-acetylcysteine group was 29 mg in 24 hours, that the difference was statistically significant between two groups (P=0.01) Conclusion: As the results of the study, it can be concluded that the anti-inflammatory effects N- acetylcysteine can inhibit the function of lipoproteins and prostaglandins, reduced glutathione peroxidase and dismutase has been restored and can be used to treat pain or analgesic dose reduction. In this study the N-acetylcysteine has reduced pain after laparoscopy and analgesic dose of mepridine. |

Abstract
Background: Urinary tract infections are very common in patients with high blood pressure. Hypertensive patients experience an average of three times of urinary tract infection per year. Blood pressure control is very important for preventing complications and also for identifying high-risk groups. Since, there is no national related study in this regard, the present study was conducted to investigate the effect of chronic hypertension on the incidence and recurrence of urinary tract infections.
Methods: In this case-control study, the required data were collected from outpatient cases referring to Taleghani Hospital and Sina Hospital related to Tabriz University of Medical Sciences in Tabriz city, Iran. Data needed for the control group included patients accompanying patients who had no symptoms of urinary tract infection and with no history of blood pressure.

Abstract
Today, the use of information and communication technology (ICT) is an important and key factor in the progress of all organizations, including health-centered and health systems. Given the importance of the subject matter above, these organizations have created a particular transformation and change in order to upgrade their systems in use, one of which is the creation of Electronic Health Records (EHR). This evolving system, by increasing productivity, both by increasing staffing efficiency and by increasing the effectiveness of the treatment process, simplifies the diagnosis path to treatment and prevents the submission of written and bulky reports. Given the ethical principles of protecting the privacy of patients and the confidentiality of their information, how to archive electronic medical records in a secure database is very important. This is one of the most important issues of ethics and hospital managers should provide mechanisms to keep all patient data properly stored and maintained. In this paper, we have tried to provide a model for the Electronic Health Record Hospital, which many of them could use to optimize their medical records systems. The purpose of this model is to accelerate and apply the process of creating electronic records in the health system, especially government hospitals with a large number of patients. By using this model, internal and external interaction of organization is facilitated, and agile responsiveness can be provided at a given time. In addition to the above, with the implementation and operationalization of the model, the possibility of reducing the volume of criticisms and complaints from hospitals will also be realized and the use of drugs will be based on the actual needs of the community and based on individual data. Implementation of this model also has barriers to addressing some of them in this article, but in order to overcome these barriers, more administrative effort and wider governmental support are needed. These efforts in the context of culture-building use of information technology, both among hospital personnel and among patients and healthcare users, are more important.

Abstract
The members of Mycobacterium tuberculosis complex (MTBC) known as causative agents of human tuberculosis. Tuberculosis infection is one of the most important occupational risks for healthcare workers (HCWs) in most countries, such as Iran. In general, there are two types of tuberculosis, they include: latent infection and active TB. Latent tuberculosis infection (LTBI) means: a patient is infected with Mycobacterium tuberculosis but, the patient does not have active tuberculosis, clinical symptoms and radiological findings. According to studies, TB infection from patients to health care workers, depending on geographic region and economic situation is two to five times more than general population. The lowest incidence and the highest rates of LTBI prevalence among HCWs were 7% in Mashhad and 82.8% in Zahedan respectively. The risk factor acquisition of TB infection was a significant relationship with certain hospital wards (lung disease unit, laboratory, etc.), Increasing age and duration of employment. And results of this study show that TB is a significant problem among HCWs in Iran. Infection control and personal protective measures with training programs to patients and HCW is required to reduce the occupational risk of TB. Early detection of Mycobacterium tuberculosis and prevention treatment in people with latent TB are key elements in control of tuberculosis. Until now, different methods for detection of latent tuberculosis infection has been introduced that are not gold standard none of them. However, the most important methods, tuberculin skin test and the tests that based on measuring the production of interferon gamma are recommended, but each one of them has advantages and disadvantages. However, in all the articles of the tuberculin skin test is used for screening and early diagnosis of latent tuberculosis infection. So, the aim of this study was to Incidence and prevalence of latent tuberculosis infection in health care workers and risk factors, advantages and disadvantages of each method for diagnosis of latent tuberculosis infection and evaluate different strategies for reducing the incidence of latent tuberculosis infection in health care workers.

Abstract
Background: Most of colorectal cancers arise from intestinal polyps. Evaluating of the expression level of genes that are involved in tumors growth and development, may consider as diagnostic factor of malignancy in the polyps. Failure of apoptosis is one of the causes of cancers. One of the key molecules in this pathway is Bid gene which connects the extrinsic to the intrinsic apoptosis pathways. The aim of this study was to investigate the quantitative expression of Bid gene in colorectal adenomatous polyps compared to control group.
Methods: The investigated population was chosen from the cases with colonic polyps that referred to the Taleghani Hospital, Tehran, Iran, from April 2014 to May 2016. 22 biopsy samples from patients with adenomatous polyps and 10 samples from healthy individuals as control group were selected. Demographic and clinical properties were collected from patients' files. The Bid gene expression was evaluated using Real-time PCR by ABI 7500 (Applied Biosystems Inc., Foster City, CA, USA). Results were analyzed by the ABI 7500 system SDS version 2.3 and GraphPad Prism, version 5 (GraphPad Software Inc., La Jolla, CA, USA). the expression changes of the intended gene in target groups were compared with the normal tissues using the 2-∆∆CT equation.
Results: Based on the quantitative real-time PCR, the gene expression of Bid gene significantly increased in adenomatous polyps in comparison with the control group (healthy individuals) (RQ>2). Also, polyps were seen in ascending colon, transverse colon, descending colon and rectum showed increased expression compared to control group, but in the sigmoid section of the intestine, there was no change in expression of Bid gene compared to control group.
Conclusion: According to the present study, the expression of Bid gene increased in adenomatous polyps, compared with the normal tissue (healthy group). It suggests that Bid gene by increasing the expression in response to the onset of dysplasia and disruption of the apoptotic cycle, it tries to compensate for the apoptosis.

Abstract
Background: One of the most important causes of chronic liver disease is hepatitis C virus (HCV), which causes liver cirrhosis and hepatocellular carcinoma. To control the prevalence of the disease, knowledge and information in risk factor of HCV are required. The aim of this study was to compare the risk factors of infection between HCV patients with genotypes 1a and 3a.
Methods: This is an observational analytical study. HCV patients who referred to the clinic of hepatology, Rasoul-e-Akram University Hospital from July 2015 to July 2017, were assigned to the genotype 1a and 3a. Demographic (age, sex, family history), clinical (cirrhosis, hepatocellular carcinoma) and laboratory data, history of intravenous drug and alcohol usage, and history of imprisonment were gathered and compared between two groups. All the patients completed the informed consent form. Data analysis was performed by SPSS software, version 22 (IBM SPSS, Armonk, NY, USA). P value less than 0.05 was considered statistically significant.
Results: Overall, 97 HCV patients were included in this study. Mean age was 45±12 years and 78 (80%) of patients were male. Among them, 58 (60%) and 39 (40%) had genotype 1a and 3a. respectively. History of injection drug usage was recorded in 34/39 (87%) of patients with genotype 3a, and significantly higher in genotype 3a as compared to genotype 1a [OR adj: 3.1, CI (1.3-6.2)]. Also, in this study, genotype 3a was significantly recorded in younger patients [OR adj: 1.7, CI (1.2-4.1)]. However, cirrhosis and hepatocellular carcinoma was more common in patients with genotype 1a as compared to genotype 3a [OR adj: 2.05, CI (1.6-5.4) and OR adj: 2.8, CI (1.3-5.7)] respectively.
Conclusion: According to the results of this study, hepatitis C virus transmission risk factors differed in genotypes 3a and 1a. Genotype 3a is found among young patients with a history of intravenous drug usage and genotype 1a in patients with cirrhosis and hepatocellular carcinoma.

Abstract
Background: Coronary artery bypass surgery is one of the surgeries in which high blood transfusions are needed. About 20% of all surgical operations require a blood transfusion. Packed cell administration increases perioperative morbidity and mortality. In the United States, from every 1000 people, one has undergone a coronary artery bypass graft surgery, and it is estimated that around 800,000 coronary artery bypass grafts undergo each year. Knowledge about relative blood administration during coronary artery bypass graft surgery improves the ability of blood transfusion centers in healthy and adequate blood donations. For this purpose, this study was conducted to determine the effective factors in the need for blood in a coronary artery bypass graft surgery.
Methods: This cross-sectional study was performed on 317 patients undergoing coronary artery bypass graft surgery in the heart surgery operating room of Imam Khomeini Hospital in Tehran, Iran, from September 2017 to February 2018. Sampling method has been available. The data of this study were extracted from patient files. The products analyzed in the study included packed cell, fresh frozen plasma and platelets. Demographic data, type of surgery, transfusion of blood and products, and hemoglobin level have been reported. P-value less than 0.05 was reported as meaningful.
Results: In this study, 317 patients underwent coronary artery bypass graft surgery. 236 cases (74.4%) were male and the rest were women. The mean of administration of packed cell in women was 2.74±1.3 and in men it was 2.29±1.09 (P<0.001). The mean packed cell administration in patients with hemoglobin levels less than 10 g/dl was 3.27±1.8 and in patients with hemoglobin levels greater than 10 g/dl was 0.99±2.25 (P<0.0001).
Conclusion: The present study showed that the mean transfusion of packed cells in women were more than men in coronary artery bypass graft surgery. Also, hemoglobin levels were the only factor that had a significant effect on infusion of packed cells.

Abstract
Background: Molecular detection has recently been proposed by nucleic acid amplification, known as polymerase chain reaction (PCR). The aim of this study was to compare the diagnostic method of smear and polymerase chain reaction with culture in terms of sensitivity, specificity, positive and negative predictive value in the diagnosis of pulmonary tuberculosis.
Methods: In this cross-sectional study, sputum samples were collected from 58 patients with suspected pulmonary tuberculosis referred to Ghaem Hospital in Mashhad from the beginning of April 2017 to the end of March 2018. The samples were delivered to the laboratory in less than 72 hours. Patients were sampled for three times. Bronchoscopy and Broncho alveolar lavage were performed in patients who were unable to produce sputum. The smear test was reported by Ghaem’s Laboratory after 24 hours. In our study, the culture method was considered as the gold standard and the sensitivity and specificity of the PCR methods and smear were compared with it.
Results: Patients ranged in age from 18 to 89 years. Among 58 suspected pulmonary tuberculosis, the method of cultivation confirmed the presence of the disease in 25 cases (43.1%). However, with smear, the presence of the disease has been proved in 27 patients (46.6%) and with the method of PCR in 24 patients was (41.4%). Sensitivity of smear in the diagnosis of pulmonary tuberculosis was (100%), and its specificity was 93.9%, the positive predictive value of this test was (92.6%) and the negative predictive value was (100.0%). The sensitivity of the PCR method in diagnosis of pulmonary tuberculosis was 88.0% and its specificity was 93.9%. The positive predictive value of this was (91.7%) and the negative predictive value was (91.2%).
Conclusion: In this study, between the two methods of smear and polymerase chain reaction, the acid fast smear method was more sensitive to the diagnosis of pulmonary tuberculosis than the polymerase chain reaction and the specificity of both methods were the same.

Abstract
Background: The amount of anterior tibial translation during rehabilitation exercises is a key factor in organizing exercise regimen after anterior cruciate ligament injury. Excessive anterior tibial translation could increase the magnitude of tension imposed on injured and reconstructed anterior cruciate ligament knees. Forward lunge and open-kinetic knee extension exercises are commonly used in anterior cruciate ligament rehabilitation. However, there is insufficient data about the amount of anterior tibial translation in the eccentric and concentric phases of these exercises. This study compared the amount of anterior tibial translation in the eccentric and concentric phase of the lunge and seated knee extension in anterior cruciate ligament deficient and intact knees.
Methods: Using a non-probability sampling method, 14 men with unilateral anterior cruciate ligament rupture were selected for participation in this cross-sectional study. Participants were recruited from the university’s physiotherapy clinics. A uni-plane fluoroscope was used to image the knee joint while participants performed the forward lunge and open-kinetic knee extension exercises with the intact and injured legs in random order. Fluoroscopy imaging was performed in the radiology center at Sina Hospital, Tehran, Iran, from September 2013 to February 2014. Two factorial mixed ANOVA was used to analyze the data.
Results: There were no significant differences in the anterior tibial translation between the limbs and contraction phases during the lunge exercise. During open-kinetic knee extension, the anterior tibial translation in anterior cruciate ligament deficient knees was significantly more than that of healthy knees at 0⁰ (P=0.007). The anterior tibial translation in the eccentric phase of open-kinetic knee extension at flexion angles of 0⁰ (P=0.049) and 15⁰ (P=0.024) was significantly greater than that in the concentric phase.
Conclusion: In the lunge exercise, the amount of anterior tibial translation was similar between the eccentric and concentric phases and the intact and anterior cruciate ligament deficient knees, however, during open-kinetic knee extension exercise, in the eccentric phase was greater than that in concentric, and in the intact knees was greater than that in the intact knees, at 0-15⁰ angles.

Abstract
Background: Herpes simplex virus (HSV) encephalitis is the most common cause of sporadic encephalitis, with significant morbidity and mortality that are effectively reduced by antiviral treatment. Herpes simplex infection in pregnant women rarely results in encephalitis. The most common symptoms of a pregnant woman with herpes simplex infection are colds and skin vesicles. Herpetic encephalitis occurs during pregnancy in the third trimester in 60% of cases and with less prevalence in the second trimester. Among HSVs most, HSV-1 causes encephalitis. Early diagnosis and timely treatment are important as mortality decreases from 70% to 20-30%. This case report, reviews a pregnant woman with a diagnosis of herpes encephalitis due to seizure and consciousness disorder, which was negative in polymerase chain reaction (PCR) assay and diagnostic studies.
Case Presentation: The patient was a 23-year-old woman with a gestational age of 29 weeks who presented with fever, headache, delirium, and cognitive impairment three days prior to admission following seizure. Early magnetic resonance imaging (MRI) showed an increase in the cortical signal in the temporal lobe and PCR assay for the detection of herpes virus was negative. Magnetic resonance venography also showed an increase in the left maxillary sinus with differential diagnosis of herpetic encephalitis. Considering the symptoms of the patient with a strong suspicion of herpes simplex encephalitis, the patient was treated with acyclovir, which was associated with improvement of clinical symptoms. Finally, normal delivery was performed after 36 weeks of gestation.
Conclusion: Given that herpes simplex virus encephalitis is a rare and potentially dangerous and complicated disease, it is imperative for a pregnant patient with atypical symptoms to be identified with an appropriate diagnostic and therapeutic measures.

Abstract
Background: Alzheimer dementia as the most common cause of dementia is a chronic, progressive, irreversible and incurable disease. The second most common cause of dementia after Alzheimer is vascular dementia. One of the systems involved in dementia is the visuospatial system and visual evoked potential (VEP) can be one of the diagnostic methods for this disease. Therefore, the present study aims to compare visual evoked potential changes in Alzheimer dementia, vascular dementia and patients with minimally conscious impairment (MCI) with healthy people.
Methods: A case-control study was performed on referred clients to Shariati Hospital, Tehran, Iran, from April 2015 to September 2016. Patients with cognitive impairment went through Montreal cognitive assessment (MOCA) test and divided into three groups of Alzheimer dementia, vascular dementia and patients with minimally conscious impairment. Subjects with normal cognition were included in the control group. The visual evoked potential test was performed on all participants in two Methods: pattern shift visual evoked potential (Ps-VEP) and flash visual evoked potential (f-VEP) and results were compared between groups.

|
Results: Forty patients were studied in four groups (three patient groups and one control group). 70 percent in Alzheimer group and 60 percent in vascular dementia group had abnormal pattern shift visual evoked potential. Only in Alzheimer group visual evoked potential P100 latency was significantly higher than control group and in other groups, there was no significant difference. Also there was no significant difference between groups in the study of flash visual evoked potential variables including P1, N2, P2 and N3.
|
Conclusion: This study showed that only Alzheimer was associated with a significant increase in visual evoked potential P100 latency. On the other hand the other hand, there was no significant difference in flash visual evoked potential variables including P1, N2, P2 and N3 between different groups which shows that flash visual evoked potential cannot differentiate between Alzheimer dementia, vascular dementia, patients with minimally conscious impairment and normal people.

Abstract
Background: Excessive and irrational use of antibiotics in the treatment of acute diarrhea has caused increased resistance to these medications. It is well defined that most cases of diarrhea in children do not require the use of antibiotics. This study was aimed to determine the status of antibiotic administration for treatment of acute diarrhea in children younger than five years. All who admitted at the pediatric ward of Besat Hospital in Sanandaj.
Methods: First, the study was approved by the ethics committee of Kurdistan University of Medical Sciences. The archived files of all children under 5 years with a positive history acute diarrhea who were admitted in Besat Hospital of Sanandaj during the period of 1 years, from May 2016 to May 2016 were reviewed. Demographic information such as age, gender, type of diarrhea, type of nutrition, type of the prescribed antibiotic, results of the stool and blood samples were collected and recorded in the questionnaire.In Stool samples the contained a large number of WBCs and RBCs along with high fever, Shigellosis were considered. The results were analyzed by SPSS software, version 23 (SPSS Inc., Chicago, IL, USA).

Results: A total of 1,029 cases were reviewed. 60% were boys. The highest incidence of diarrhea (75.5%) was observed at 12-24 months and the lowest rate of diarrhea was under 6 months (11.5%). The frequency of diarrhea was lower in winter than in other seasons. Only 31.49% of children received proper and rational treatment with antibiotics. The most commonly used antibiotics in hospitalized patients were ceftriaxone (94.5%) and before hospitalization was cefixime (39.5%). Based on the results of this study, it was found that 66.13% of children younger than 5 years with acute diarrhea had appropriate treatment. 31.94% of patients had inappropriate antibiotic therapy.
Conclusion: In most cases of acute diarrhea in children, no evidence of bacterial or parasitic infection was found. However, a high percentage of patients received antibiotics without laboratory evidence (stool testing). |

Abstract
Background: Early diagnosis of patients in the early stages of Alzheimer's, known as mild cognitive impairment, is of great importance in the treatment of this disease. If a patient can be diagnosed at this stage, it is possible to treat or delay Alzheimer's disease. Resting-state functional magnetic resonance imaging (fMRI) is very common in the process of diagnosing Alzheimer's disease. In this study, we intend to separate subjects with mild cognitive impairment from healthy control based on fMRI data using brain functional connectivity and graph theory.
Methods: In this article, which was done from April to November 2020 in Tehran, after pre-processing the fMRI data, 116 brain regions were extracted using an Automated Anatomical Labeling atlas. Then, the functional connectivity matrix between the time signals of 116 brain regions was calculated using Pearson correlation and mutual information methods. Using functional connectivity calculations, the brain graph network was formed, followed by thresholding of the brain connectivity network to keep significant and strong edges while eliminating weaker edges that were likely noise. Finally, 11 global features were extracted from the graph network and after performing statistical analyses and selecting optimal features; the classification of 14 healthy individuals and 11 patients with mild cognitive impairment was performed using a support vector machine classifier.

Results: Calculations were showed that the mutual information algorithm as a functional connectivity method and five global features of the graph network, including average strength, eccentricity, local efficiency, coefficient clustering and transitivity, using the support vector machine classifier achieved the best performance with the accuracy, sensitivity and specificity of 84, 86 and 93 percent, respectively.
|
Conclusion: Combining the features of brain graph and functional connectivity by the mutual information method with a machine learning approach, based on fMRI imaging analysis, is very effective in diagnosing mild cognitive impairment in the early stages of Alzheimer’s which consequently allows treating or delaying this disease.

Abstract
Background: In the present study, we hypothesized that conditioned medium (CM) derived from mesenchymal stem cells attenuates the brain oxidative stress in sepsis induced by the cecal ligation and puncture (CLP) model.
Methods: This study was performed in the Department of Physiology at Tehran University of Medical Sciences from August 2018 to April 2019. Conditioned medium was collected from mesenchymal stem cells isolated from rat's adipose tissues at the second culture passage. Male Wistar rats weighting (220-250 g) were randomly divided into three experimental groups (n=8 each): Sham, Sepsis and CM. Sepsis was induced by cecal ligation and puncture model in the Sepsis and CM groups. Animals in the CM group received the conditioned medium from 5×105 mesenchymal stem cells (2 h after sepsis induction, i. p., 3-5 mL). The systolic blood pressure and O2 saturation were measured 24 h after the treatment. The plasma and brain tissue samples were taken for inflammatory and oxidative stress assessment, respectively.
| Results: Septic rats showed a significantly lower systolic blood pressure and O2 saturation level. They also had a significant increase in the plasma inflammatory indices (tumor necrosis factor-alpha [TNF-α], interleukin-6 [IL-6]) and brain malondialdehyde (MDA) content as well as a significant reduction in the brain superoxide dismutase (SOD) activity compared to the Sham group. The CM group had significantly higher systolic blood pressure and O2 saturation level compared to the septic rats. The animals in the CM group showed a significant attenuation in the plasma inflammatory indices (TNF-α and IL-6) and brain MDA content while having a significantly higher brain SOD activity compared to the Sepsis group. Conclusion: Our findings showed that conditioned medium derived from mesenchymal stem cells has protective effects in preventing the inflammatory and oxidative stress status and may be suggested as a promising treatment in patients suffering from sepsis and septic shock. |

Abstract
Background: Time management is effective in controlling stress especially for medical residents. Time management in the surgical field and residential education is very important as they are directly involved in treating patients. Proper time management will help decrease work-related stress and increase efficacy, although there is no time management in medical courses. There are few studies in Iran in this field. So, we designed this study to assess the effects of time management on improvement of educational and therapeutic services in surgical residents of Imam Hospital.
Methods: This before–after study was done in Imam hospital between February-March 2015. In this before-after study, 18 surgical residents of Imam Hospital (residents of 1-4 years), were enrolled. Their activities were evaluated in 11 scopes. To evaluate the effects of this self-evaluation, 5 scopes were assessed by the staff. The time during two weeks spent on each item was claimed as a percentage of 336 hours in two weeks. The self-assessment results and their effects on their scores were considered. Data regarding age, sex, and marital status were also gathered. Data were analyzed using SPSS software.

Results: Eighteen residents were enrolled in this study. Ten residents were male (55.6%) and eight were female. Six (33.3%) were married. The mean age was 30±3.7 years. Resting time and emergency room time were significantly higher in the first-year residents while studying time was higher in the fourth-year residents. Second-year residents spend more time in training classes than others. The mean score at the beginning and the end of the study was highest in the forth-year residents and lowest in the first-year residents. All scores at the end of the study were significantly higher than the beginning except clinical judgment. The increase of the mean overall score was significantly higher in the fourth-year group and lowest in the first-year group.
Conclusion: Time management could improve the educational performance of surgical residents. |

Abstract
Background: In patients with ST-segment elevation myocardial infarction (STEMI), Primary percutaneous coronary intervention (PCI) is the preferred reperfusion therapy. Timely primary PCI is essential in improving the clinical outcomes of these patients. The aim of this study was to evaluate the factors affecting balloon delay in STEMI treated patients by primary PCI and its relationship with major adverse cardiac events (MACE).
Methods: This prospective observational study was conducted on 143 cases of STEMI patients, who had the inclusion criteria and were treated by primary PCI, after obtaining written consent in Imam Khomeini hospital in Ahvaz, between May 2019 to May 2020. All-time components from symptom onset to PCI treatment include symptom-to-balloon time or ischemic time, symptom-to-door time and door-to-balloon time calculated. The incidence of major adverse cardiovascular events (MACE) including decompensated heart failure (DHF), acute coronary syndrome (ACS), sudden cardiac death (SCD) and cerebrovascular accident (CVA) was evaluated during 12 months follow up after primary PCI. left ventricular ejection fraction (LVEF) changes were evaluated 3 months after primary PCI.
| Results: The median symptom-to-door time was 200.5 minutes (IQR: 90-438.75 min), the median ischemic time was 406 minutes (IQR: 231-671 min), and most patients had an ischemic time ≥120 minutes (92.4%) and door-to-device time ≥90 minutes (64.3%). The most common delay for treatment was in the symptom-to-door time (76.9%) and then the decision for primary PCI to transfer to the cat lab (17.5%). Overall, 59 (41.3%) of the patients experienced MACE during 1-year of follow-up, including ACS (13.3%), DHF (22.4%), cardiac death (9.8%) and CVA (2.1%). The patients age (OR: 0.96, P=0.020), LVEF changes (OR: 1.123, P=0.005) and STEMI type (OR: 0.705; P=0.039) predicted in-hospital MACE, while the symptom-to-balloon time (P=0.607) and door-to-balloon time (P=0.347) were not associated with MACE. Conclusion: None of the time intervals were associated with the occurrence of MACE in one-year follow-up, and most STEMI patients were admitted to the hospital with a long delay. Therefore, efforts to shorten the time of hospitalization admission can help improve the MACE in STEMI patients under primary PCI in our medical centers. |

Abstract
Background: The patient's position during the recovery time after arthroplasty surgery can be a factor in reducing complications and improving patients’ condition. Therefore, this study was performed to compare the knee range of motion after soft tissue repair in both flexion and extension positions of total knee arthroplasty.
Methods: This study is a double-blind clinical trial. The study population was all candidates for total knee arthroplasty surgery in Al-Zahra and Kashani hospitals in Isfahan from July 2011 to September 2012. The sample size was selected using the statistical formula of 88 patients and randomly divided into two groups of flexion and extension. In the first group during the knee soft tissue repair, the knee was in flexion and in the second group it was in extension and then it was repaired. Information such as age, sex, body mass index and surgical position were recorded in the checklist. The knee range of motion was measured at the end of the first, second, fourth, eighth and twelfth weeks and recorded in a checklist. In order to compare the pattern of changes in mean knee range of motion over time in the two groups, mixed linear models and conventional marginal models to generalized estimator equations were used by STATA software.

Results: The results showed that there was no significant difference between the flexion and extension groups in knee range of motion. In both groups, the mean knee range of motion increased with time (P<0.001). The mean scores of knee function after the end of the twelfth week in the flexion and extension groups were 141.04±23.19 and 143.09±22.34, respectively, and this difference was not significant.
Conclusion: Soft tissue repair in a particular position is not so effective on the outcome that we want to institutionalize it by spending a considerable amount of budget for training surgeons. |

Abstract
Background: Due to the chronic nature of diabetes, children with type 1 diabetes are prone to a number of long-term complications. One of the most important complications of this disease is cardiovascular involvement due to atherosclerosis, which is directly related to the control of blood lipids. The use of probiotics may be effective in the process of complications in these patients by affecting fat metabolism. The aim of this study was to evaluate the effect of oral probiotics on lipid profiles in children with type 1 diabetes.
Methods: This study was conducted at Bahrami Children's Hospital from May 2018 to May 2019. In this single-blind randomized controlled clinical trial, 52 children with type 1 diabetes (aged 2 to 16 years) were studied. We created two groups of 26 individuals. The inclusion criteria were determined as follows: Proof of T1DM by history and information of children’s medical record. Also, the Exclusion criteria were determined in this way: Patients consuming probiotics in the last 4 weeks, gastrointestinal infections in the last 2 weeks, and presence of chronic underlying intestinal diseases. The probiotic group received, in addition to insulin therapy, a daily probiotic capsule for 90 days. The control group received only routine insulin therapy. Blood samples were taken to measure lipid profiles at the beginning and end of the trial.
Results: A total of 52 patients were included. The mean age of children was 9.3±2.9 (4 to 14 years). The mean age in the probiotic and control groups was 9.6±3.5 and 9.4±3.0 respectively. The results of this study showed that HDL-C was increased in the probiotic group compared to the control group, although it was not statistically significant (P>0.05). Also, changes in total cholesterol, LDL-C, and triglyceride were not statistically significant.
