Abstract
Background: Laryngoscopes are one of the potential mediators of infection transmission due to their blades contact with oral mucous membranes. Using single-use plastic blades is a method of preventing infection transmission. The aim of this study is to compare the efficiency of single-use plastic and reusable metal laryngoscope blades in orotracheal intubation during the rapid- sequence induction of anesthesia
Materials and Methods: In this clinical-trial, 310 patients, more than 10 years of age, who were candidates for elective surgery, were selected. After anesthesia induction, orotracheal intubation was done by either single-use plastic or reusable metal blades for patients. Duration of intubation and arterial oxygen saturation were recorded before and after intubation. Data analysis was done using SPSS software.
Results: Orotracheal intubation was done successfully in all patients. Mean differences of intubation time from the standard upper limit were 1.42±8.19 and 13.1±4.22 seconds in the plastic and metal blades groups, respectively. Also, the mean of difference in oxygen saturation of the low 90% after intubation were 6.07±2.71 and 7.16±1.21 in plastic and metal blades groups, respectively. Both parameters indicated statistically significant differences.
Conclusion: In rapid-sequence induction of anesthesia, by using single-use blades, both intubation time and arterial oxygen saturation drop will increase in comparison with metal blades. This will cause complications such as aspiration in the patients.

Abstract
Background: Addiction is undoubtedly one of the biggest problems of human societies that every year governments spend enormous amounts of money on fighting it. Most addicts, besides their addiction, cause many psychological problems in their families therefore, the aim of this study was to compare the presence of these disorders between the families of addicts and non-addicts. Materials and Methods: This case-control study was done on a sample of 650 persons of opium addicts' and non-addicts' families using random sampling method. Data were collected through SCL-90-R questionnaire and were analyzed by Chi-square and t-test using SPSS software version 18. Results: There was a significant difference in psychiatric disorders in addicts' and non-addicts' families (p=0.005). Among the 9 psychiatric disorders under assessment, only anxiety, aggression, paranoia, and depression disorders in three types, including pathologic, borderline, and combined (pathologic-borderline), were significantly higher in addicts' families compared with non-addicts' families (p=0.005). Conclusion: Drug dependence disorder in one member of a family has a very important effect on the mental hygiene of the other family members and requires prevention and treatment in both.

Abstract
Background: Metastasis or compress effect of adjacent tumors and thyroid neoplasms are the most common causes for airway obstruction which may lead to emergent intubation or tracheostomy due to respiratory distress. Case: A 61 year-old, female patient with history of papillary cell carcinoma with metastasis to lung, trachea and vocal cords was referred to our hospital with complaint of dyspnea. In the early hours of hospital admission the patient suffered from attacks of apnea and gasping, and initial efforts to control the airway were performed immediately which were not successful. Then it was decided to perform broncoscopy and tracheostomy to provide a safe airway. Conclusion: In the absence of adequate equipment and emergency respiratory situation, it is better to provide a secure airway immediately. For this purpose, we can use low depth of anesthesia without use of muscle relaxants.

Abstract
Background: The use of propofol alone for insertion of supraglottic devices can lead to undesirable events such as cough, gagging, and laryngeal spasm. Narcotic drugs are used to improve the insertion of these devices. In this study, the effect of two narcotics, remifentanyl and sufentanyl, on ease of insertion of two types of supraglottic airway devices were evaluated. Materials and Methods: In this clinical trial, 200 patients undergoing general anesthesia were divided into four groups through blocked randomization. Induction of anesthesia was performed using propofol 2.5 mg/kg. Then the first group received remifentanyl and laryngeal mask, the second group remifentanyl and SLIPA, the third group sufentanyl and laryngeal mask, and the fourth group sufentanyl and SLIPA. The amount of jaw opening, ease of insertion of supraglottic devices, cough, laryngospasm, gag reflex, heart rate, and arterial blood pressure were recorded one, three, and five minutes after insertion of supraglottic devices. Results: No significant differences were observed in the amount of jaw opening, ease of insertion of supraglottic devices, cough, laryngospasm, gag reflex, and hemodynamic parameters between the four groups. Conclusion: The results of our study indicated that for controlling airways using supraglottic devices, use of laryngeal mask or SLIPA in the presence of remifentanyl or sufentanyl have no priority over each other and do not lead to hemodynamicimpairement

Abstract
Background: Post-anesthetic shivering is the most common cause of patient discomfort during recovery with a prevalence of 5 to 65%. Post-anesthetic shivering can increase pain, oxygen consumption, and cardiac output. The aim of this study was to compare the efficacy of various classes of drugs for preventing post-anesthetic shivering.
Materials and Methods: In this double-blind clinical trial, patients undergoing elective laparotomy were randomly divided into six groups, 40 each. The patients, respectively, received hydrocortisone, ketamine, tramadol, magnesium sulfate, pethidine, and normal saline. All patients were observed for body temperature and shivering for 20 minutes after arrival to recovery room.
Results: Seventy patients in the pethidine group did not have shivering upon arrival to recovery room which was significantly higher than other groups (&chi2=0.00002). Also, the patients in the pethidine group did not shiver 10 and 20 minutes after arrival to recovery room that was significantly lower than other groups.
Conclusion: According to the results, it can be concluded that pethidine is more effective than other drugs in prevention of post-anesthetic shivering.

Abstract
Background: Physical activity and overweight both changethe body homeostasis for this purpose, in this study effect of two models of high and moderate intensity aerobic exercises on the amount of Adiponectin and Resistin were compared inobese and overweight females.
Materials and Methods: In this experimental study, 15 obese and overweight female (Mean age: 22.93±0.54 years weight: 75.15±2.07 kg hight: 160.6±1.38 Cm BMI: 29.24±0.73kg.m-2) were randomly selected as sample. Subjects were placed into high (33 min exercise, 85-90% of max hearat rate) and moderate (41 min exercise, 50-70% of max hearat rate) intensity aerobic exercise groups. Exercises lasted three days a week for eight weeks with an equal volume of consumed energy. In order to analyze data, independent-t test and Repeated Measure analysis of variance were used at a significance level of p<0.05.
Results: The results indicate a significant increase in Adiponectin after eight weeks of high-intensity aerobic exercise compared to moderate-intensity exercise (p=0.02). A significant reduction in fat mass and percentage was observed after moderate intensity exercise (p=0.03), too. In Addition, moderate intensity exercise caused a considerable decrease in Resistin after eight weeks (p=0.06).
Conclusion: High-intensity exercise appears to provide necessary metabolic stress to enhance Adiponectin, even without weight and fat loss.

Abstract
Background: Unpleasant side effect of awareness within general anesthesia is potentially an important concern in patients. The patient may sleep during anesthesia and feels the pain due to loss of pain suppression of sensory perception of pain during surgery. The aim of this study is to determine the effect of BIS monitoring on level of awareness during anesthesia in women undergoing elective caesarean section.
Materials and Methods: In this double-blind, randomized clinical trial, 214 ASAI–II patients, over 15 years of age, candidate for elective cesarean section were included in the study. Patients randomly divided to two groups of anesthesia with and without BIS monitoring. Patients were assessed for awareness within anesthesia immediately, 24 hours, and 3-6 days after operation.
Results: From 107 patients without BIS monitoring, 8 patients (7.4%) suffered from awareness during anesthesia and their awareness score was two and greater than two. While none of the patients in the BIS group experienced awareness during anesthesia. Level of awareness during anesthesia in the control group was significantly more than the BIS group (p<0.0000).
Conclusion: The incidence of awareness during anesthesia is significantly lower in BIS monitored group than the control group.

Abstract
Background: Atrial fibrillation (AF) is the most common complication after coronary artery bypass graft surgery (CABG). This complication causes an increase in morbidity and mortality after CABG and also increases the length of ICU stay and hospitalization. The aim of this study is to evaluate the prophylactic effect of amiodarone in reducing the incidence of post CABG atrial fibrillation.
Materials and Methods: In this clinical trial study, 204 patients, candidate for elective CABG, entered the study according to inclusion and exclusion criteria, and randomly divided into two equal groups. The case group received 300 mg of intravenous amiodarone before anesthesia induction and the control group received normal saline. Incidence of AF was recorded until 24 hours after CABG.
Results: The incidence of post CABG AF was 16 patients in the case group and 35 patients in the control group. Comparison of the frequency of AF between groups by Chi square analyses showed a significant difference (p=0.037) and the incidence of AF was significantly lower in the amiodarone group.
Conclusion: In total, amiodarone could significantly prevent the incidence of atrial fibrillation after coronary artery bypass surgery. In this study, patients took this medication only in the first 24 hours, while in some studies, this drug has been prescribed for even 14 days.

Abstract
Background: Hydatidosis is one of the dengerous zoonotic diseases that cause serious problems for human health, as well as major economic losses for livestock industry. Due to the nature of the parasite life cycle and also the structure of the cyst in human, the control of parasite in community is difficult and its treatment has faced with a major challenge. One of these challenges is inactivating the protoscolices for treatment purposes and preventing secondary cysts. Different chemicals have been used in the treatment of cyst that most of them had serious side effects for the patient. The aim of this study was investigating the scolicidal effects of some herbal extracts in vitro.
Materials and Methods: Liver hydatid cysts were collected from slaughterhouse the cysts fluid containing live protoscolex was aspirated aseptically and stored at 4°C until use. Three concentrations (25, 50 and 100 mg per ml) of each extract (ginger and artemisia) prepared and protoscoleces placed into incubator at 37oC. The viability of the protoscoleces was determined by eosin staining method at the times 5, 10, 25, 40 and 60 minutes.
Results: The methanolic extract of ginger at the concentration of 100 mg/ml leads to kill all of protoscoleces at 40 minutes. While the artemisia extract in none of investigated concentrations had not much effect on the protoscoleces.
Conclusion: The study of animal models and complementary tests showed that methanolic extract of ginger can be used as an effective protoscolex for it has high activity.

Abstract
Background: Boredom is a psychological phenomenon that was defined as an aversive state or incompatibility with every repetitive experience while the release of stability is not allowed. Boredom has several complications. So, the goal of this study is to compare the predictors of boredom in students of Arak University of medical sciences and Islamic Azad University.
Materials and Methods: The current descriptive-comparative study has been done on966 students (from Arak University of medical sciences and Islamic Azad University). The scale of current study was a checklist list of demographic information, predictors of boredom assess questionnaire, Farmer and Sundberg’boredom proneness scale. Data were analyzed by using chi-square, Pearson correlation, multivariate regression, and Fisher'sz.
Results: The greatest number of students from both universities have normal boredom without a statistically significant difference between male and female students (p=0.06). University factor had the highest average between students. Totally, boredom had a significant correlation with each of the home (p=0.000) and society (p=0.001) factors. All three factors including home (p=0.033), university (p=0.033) and society (p=0.031) can explain and predict boredom in male and female students.
Conclusion: The results showed that university factor was the most important factor for predicting boredom between college students. Thus, in order to avoid adverse effects of boredom on students educational activities, this phenomenon and its causes should be considered.

Abstract
Background: The incidence of gastric cancer is different in two sexes with ratio 2 to 1 that it is more common in men. The most important biologically reason is sexual hormones between two sexes that lead to sexual dimorphism and in turn can cause a sex bias in incidence of disease between two sexes. Recently, studies have shown that microRNA is involved in sexual dimorphism in gene expression. Given the sexual dimorphism in the incidence of gastric cancer and sex hormones response elements in the regulatory regions of miR-146a and miR-148a genes, in this study, the expression of these two genes in the stomach of healthy men and women at different age groups were compared.
Materials and Methods: Using endoscopy, gastric antrum tissues of 35 healthy women and 35 healthy men were collected. After RNA extraction and synthesis of cDNA, the expression of miR-146a and miR-148a genes were compared between sexes by Real time RT-PCR and data were analyzed using independent sample t and ANOVA tests.
Results: There was no difference between men and women in genes expression of miR-146a and miR-148a. However, expression of miR-146a gene was significantly more in men under 45 years than men over 45 years (p= 0.017, df= 14, t= 1.47). Also, expression of miR-148a gene was significantly more in men over 45 years than men under 45 years (p=0.001, df= 12, t= 1.28). But the expression of both genes had no significant difference between women under 45 years and women over 45 years.
Conclusion: Expression of miR-146a and miR-148a genes in the stomach is increased and decreased with aging in men, respectively.

Abstract
Background: Pain is a protective process in the body. There are different pathways for pain control in the central nervous system. Descending pain control system is one of pathways. The periaqueductal gray (PAG) is a structure known for its role in pain transmission and modulation. The aim of this study is to investigate the percent of interaction between the left and right PAG in unilateral left foot induced pain.
Materials and Methods: In this study, 60 rats (280+30g) in six groups were used (3test groups and 3 controls groups). In test groups, 0.5 microliter lidocaine was injected in the left PAG, right PAG or both to make local anesthesia. In control groups, 0.5 microliter of normal saline were injected. After 15 minutes, 50 microliter of 2.5% of formalin were injected subcutaneously to right hind paw of rats and nociception was detected in every 15 seconds for one hour.
Results: The induction of unilateral pain (left hind paw) in rats, can affect not only the ipsilateral but also the contralateral PAG nucleus.
Conclusion: This study showed that the left and right PAG nuclei have significant role on unidirectional nociception in formalin test in rats. The contralateral PAG, however, has a minor effect on nociception.

Abstract
Background: The exact diagnosis of schizophrenic disorder from schizoaffective disorder has always been a challenge for therapists due to the comorbidity of many signs and symptoms. The purpose of this study is to investigate the differential diagnosis of schizophrenia disorder from schizoaffective disorder, focusing on the emotional content of their memories.
Materials and Methods: The present study is a causal-comparative study on 23 male and female patients with schizophrenia and schizoaffective disorder (without any comorbid diagnosis). Using a clinical interview, the emotional events and memories of their lives, as well as the amount of affective and emotional words used by these patients in expressing their memories, have been assessed. To determine the differences between the two groups, the data were analyzed by Chi-square test.
Results: Results showed that men with schizophrenia had a significant difference in expressing the amount of emotional events in their lives, as well as in expressing affective and emotional words compared to schizoaffective men. But, this difference was not observed in schizophrenic and schizoaffective women.
Conclusion: The findings of this study suggest that differential diagnosis of schizophrenia and schizoaffective disorder can be made with emphasis on the emotional content of memories, especially in men.

Abstract
Background and Aim: One of the problems of children with Autism Spectrum Disorder (ASD) is behavioral excesses resistance to many educational and rehabilitation programs. Parent-mediated behavioral interventions seem to be effective in overcoming these problems. However, these methods are not well-introduced. The purpose of this study is to systematically review these studies and their primary and secondary outcomes, and finally analyze the components.
Methods & Materials: This study was a systematic review. The search included SID, Magiran, Medline, PubMed, Springer, Science Direct, Online Library, and PsycINFO. We reviewed The articles published between 2000 and 2017 about parent-mediated behavioral interventions on behavioral excesses in autistic children.
Ethical Considerations: This study with ethical code IR.SBU.ICBS.97/1013 was approved by the Biological Research Department of Shahid Beheshti University.
Results: The findings of 9 studies indicated positive effects of parent-mediated behavioral intervention on behavioral excesses, including repetitive behaviors, irritability (including tantrums, aggression, and self-injurious behaviors), echolalia, and destructive behaviors (preliminary results). Also, these interventions improved the adaptive behaviors in autistic children, and parental functions such as self-efficacy, parental style, psychological problems (secondary results). Components of the therapeutic program included the type of consequence-based interventions (such as response interruption and redirection), antecedent-based interventions A (visual cue and daily schedules), antecedent-based interventions B (such as enriching environment with play). Three articles had medium certainty of the evidence, and 6 had high certainty of evidence.
Conclusion: The results of this study indicated the positive effect of parent-mediated behavioral intervention on behavioral excesses in children with ASD. Future studies should emphasize the comprehensiveness of all the effective components in the parent-mediated behavioral intervention and the feasibility of the intervention in various contexts. It is suggested that parent-mediated interventions be implemented on behavioral excesses in children with ASD in Iran.
