Background: Cardiopulmonary resuscitation, commonly well-known as CPR, is an emergency technique that includes chest compression often with artificial ventilation in an exertion to manually preserve complete brain task until additional measures are taken to return spontaneous blood circulation and breathing in a person who is in cardiac arrest. According to the International Liaison Committee on Resuscitation Guidelines, CPR includes chest compressions for adults between 5 cm (2.0 in) and 6 cm (2.4 in) deep and at a rate of at least 100 to 120 per minute. Cardiopulmonary resuscitation is aimed to reverse vital organs as like as heart, lungs and for subsistence of patients. Several researches showed that different factors affect the resuscitation results. The current study was designed to assess the results of resuscitation and its association factors. |
Methods: This retrospective, descriptive and analytic study was carried out in Baharloo Hospital, Tehran, Iran during March 2014 and February 2015. In current work, all resuscitated patients were imported and patients with uncompleted files and died before entrance to hospital were excluded. The data was obtained from medical records units, office files unit and the unit of quality improvement. Data were analyzed by use of SPSS version 22 (Armonk, NY, USA) software and Chi-square test and Student’s t-test.
|
Results: From 891 patients, 813 cases were entered the study that 498 (61.3%) were male and 315 (38.7%) were female. 41.1% of resuscitation were successful and 58/9% were unsuccessful. The mean and standard deviation time of resuscitation was 28.80 and 12.6 minutes; the most frequent primary diagnosis was cardiovascular disease. In this study there was a significant difference between age and duration of the resuscitation with successful resuscitation (P= 0.02) but, in the variables of ward and resuscitation team were not significant (P> 0.05). Conclusion: The results of this study showed that resuscitation in younger group, short duration of resuscitation and patients without heart diseases are more successful. |

Background: Platelet storage is complicated by deleterious changes that cause progressive structural and functional damages, so-called platelet storage lesion (PSL). PSL is commonly manifested by augmented platelet activation which is also associated with the increased levels of reactive oxygen species (ROS). Whether ROS generation increases during the storage of platelet concentrates and whether it will be correlated with P-selectin expression as a valid marker of platelet activation was investigated in this study. Methods: In our experimental study, six PRP-platelet concentrates were randomly obtained from Iranian Blood Transfusion Organization (IBTO). All the platelet products met the standard quality assessment based on AABB guidelines. Washed platelets were subjected to flow cytometry analysis for the evaluation of P-selectin expression and intracellular ROS production using DHR 123 in day 0, 1, 3 and 5 after storage. Statistical data were analyzed by Kruskal-Wallis test with Dunn’s multiple comparison test. For correlations, linear regression analysis was applied. P values of less than 0.05 were considered to be significant. Results: Platelets ROS generation significantly increased from day 0 to day 5 of storage (P= 0.0002). This observed gradual increase was also directly correlated with the increasing levels of P-selectin expression during platelet storage (r= 0.72, P= 0.0001). Conclusion: Our study showed significant increases in ROS generation during the storage of platelet concentrates correlated with the increments of P-selectin expression as an important marker of platelet activation. This finding suggests that the analysis of ROS generation can also be considered a marker of platelet activation during storage. However, whether ROS generation first induces platelet activation or platelet activation during storage triggers ROS generation is still remain to be determined. |

Background: Doxorubicin (DOX) is a commonly used chemotherapeutic agent that causes hepatotoxicity via depletion of anti-oxidants and activation of apoptosis. Present study was aimed to investigate the interactive effects of two forced treadmill running and voluntary wheel running exercise training method and Nanocurcumin supplement on hepatic damage, in aging model subjects. Methods: This experimental research was performed in animals and exercise physiology laboratory of Faculty of Physical Education and Sport Sciences, University of Mazandaran, Iran, in April, 2014. The statistical population was eighty Wistar male rats that, received a daily injection of D-galactose solution for nine weeks (100 mg/kg body weight per day, i.p.) and then, they randomly assigned to 10 groups. The forced treadmill running protocol was progressively between 25 to 54 min/day at the intensity of 15 to 20 m/min for 5 days per week for six weeks and voluntary wheel running exercise was six weeks. DOX was administrated for 15 days (1 mg/mL/kg body weight per day, i.p.). Nanocurcumin supplement was administrated for 14 days (100 mg/kg body weight per day. orally). Superoxide dismutase and apoptosis inducing factor levels were measured by enzyme-linked immunosorbent assay (ELISA) method. Results: Implementation of two forced treadmill running and voluntary wheel running exercise with Nanocurcumin supplement, respectively led to insignificant decrease and increase in superoxide dismutase levels in comparison with the implementation of this exercise methods alone (P= 0.955 and P= 1.000, respectively). Apoptosis Inducing Factor levels following these two training method with Nanocurcumin supplement, has insignificant decrease in comparison with the implementation of this exercise methods alone (P= 1.000 and P= 1.000, respectively). Conclusion: Our findings suggest that, however implementation of these training methods with Nanocurcumin supplement, partly mitigates the side effects of doxorubicin, but this level of intervention is not sufficient to protect against doxorubicin-induced hepatotoxicity in aging model rats. |

Abstract
Background: Clomiphene citrate is very successful in inducing ovulation; there is usually a discrepancy between ovulation and pregnancy rate. If treatment is started early in the cycle this negative effect is reduced. The aim of this study was to investigate the effect of the time of administration of clomiphene citrate on follicular growth, endometrial thickness and ovulation and pregnancy rates in PCOS (Polycystic ovary syndrome) patients.
|
Methods: This randomized controlled trial study was performed on 115 PCOS (Polycystic ovary syndrome) women in Fateme Zahra Fertility and Infertility Research Health Center in April 2012. Patients randomly divided into two groups. Patients in the early group (No. 55) received 100 milligrams of clomiphene citrate tablet daily starting the next day after finishing medroxyprogesterone acetate tablet for 5 day, whereas the patient in the late group (No. 60) received 100 milligrams of clomiphene citrate tablet daily for 5 day starting on day 3 of the menstrual cycle. Then on follicular growth, endometrial thickness and ovulation and pregnancy rates by SPSS software, version 16 (Armonk, NY, USA) were compared in two groups. Results: 36.4% of patients of early administration of clomiphene and 60% of patients in the later administration of Clomiphene were able to build dominant follicle. This difference was statistically significant (P<0.011). There was no statistically significant difference between the two groups on age, body mass index, duration of infertility. Findings showed that in the early group 14 (63.6%) and in the late groups 8 (36.4%) women who made dominant follicle, were pregnant. There was significant difference between these two groups (P<0.001). But, in the number of follicles, endometrial thickness and pregnancy rate, there were no significant difference. In the early administration of clomiphene, the pregnancy rate was 25.5%. However in the later administration of clomiphene it was 13.3% (P=0.882). Conclusion: According to the results of this study, if the dominant follicle was made, with administration of clomiphene citrate in luteal phase the incidence of successful pregnancy is higher. |

Abstract
Blood transfusion is commonly implemented to manage life and health-threatening conditions on a rapid and short-term basis. Over the years, ongoing technical advances have dramatically improved transfusion medicine to provide more safety and effectiveness. However, transfusion is still complicated with different adverse events that mainly induced by the presence of allogeneic leukocytes in the blood products. Several lines of evidence have shown that leukocytes in blood components are involved in the induction of febrile nonhemolytic transfusion reactions (FNHTRs), HLA alloimmunization and platelet refractoriness as well as the increased risk of the infectious diseases transmitted by leukotropic viruses including cytomegalovirus (CMV), human T-lymphotropic virus (HTLV)-I/II and Epstein-Barr virus (EBV). During current decades, introducing various leuko-reduction techniques have shown to be associated with less transfusion related adverse events and improved clinical outcomes. The lower incidence and severity of febrile transfusion reactions; reduced risk of transfusion related transmission of CMV or other leukocyte-associated infections, lowered incidence of alloimmune platelet refractoriness in addition to reducing risk of mortality and morbidity in patients are considered as clinical benefits of leuko-reduced products. Currently, by the use of 3rd and 4th generation of filters, the highest levels of leukoreduction in blood components have been achieved. Filtration techniques have also the advantages of being performed shortly after preparation of components (pre-storage) or post-storage even at the patient’s bedside. However, it seems that pre-storage depletion of leukocytes provides better protection than post-storage techniques due to the elimination of leukocyte-derived cytokines effects which are increasingly released during storage. Particularly in platelet products, the earlier depletion of leukocyte also favors less platelet-induced leukocyte activation which may be triggered by the interaction between either activated platelets or their released chemokines and residual leukocytes during storage. Despite the benefits attributed to leukoreduction of blood components, the global use of leukoreduced products is commonly hampered by its high cost especially in developing countries in which leukoreduction of blood components is usually limited to some patients with special conditions. In this review, after briefly introducing of some transfusion adverse events that are attributed to allogeneic leukocytes existed in blood products, the effects of leukoreduction process in the attenuation of these events will be discussed.

Abstract
Background: About 90% ovarian cancers are epithelial and 10-15% of this group are mucinous. The treatment is the hysterectomy with bilateral salpingo-oophorectomy. However, most of these tumors occur in young women that have not yet given birth in which preservation of fertility should be considered. We present a case of huge mucinous cystadenoma and massive ascites managed by preserving uterus and ovaries. Meigs’ syndrome is found in fibroma, and thecoma of ovary, however, in rare occasion this syndrome is occurred in mucinous cystadenoma.
Case presentation: A 21-year-old unmarried woman presented with the complaint about weight gains and irregular menstruation for four months to gynecology clinic of Firoozgar hospital in Tehran in October 2016. Preop lab data including tumor marker was gathered, and sonography with CT scanning of pelvic and chest was performed. The ascitic fluid was negative for malignancy. Also, laparotomy with staging the ovarian tumors was carried out including cytology of ascitic-fluid, cytology of diaphragm, ovarian cystectomy, biopsy of the paracolic gutter, exploring abdomen and pelvis. Histopathology report revealed mucinous cystadenoma. Moreover, according to the normal appearance of the appendix in this case, the appendectomy was not performed.
Conclusion: Ovarian cysts in young women who are associated with elevated levels of tumor markers and ascites require careful evaluation. Management of ovarian cysts depends on patient's age, size of the cyst, and its histopathological nature. Conservative surgery such as ovarian cystectomy or salpingo-oophorectomy is adequate in mucinous tumors of ovary. Multiple frozen sections are very important to know the malignant variation of this tumor and helps accurate patient management. Surgical expertise is required to prevent complications in huge tumors has distorted the anatomy, so gynecologic oncologist plays a prominent role in management. In this case, beside of the huge tumor and massive ascites uterine and ovaries were preserved by gynecologist oncologist and patient is well up to now.

Abstract
Background: The prevalence of diabetes mellitus due to existence of various factors is growing rapidly. The insulin resistance phenomenon is one of the main underlying causes of this disease, due to various reasons such as a decrease in serum levels of vitamin D3. In this study, we evaluated the relationship between plasma level of vitamin D3 and some other main plasma factors.
Methods: This clinical trial study carried out on type 2 diabetes mellitus subjects who referred to diabetes clinic of Baqiyatallah Hospital in Tehran city during June to September 2016. First demographic data of all patients were collected. Then the blood samples for evaluation of blood glucose, HbA1c, triglyceride, cholesterol, HDL, LDL and vitamin D3 were obtained. Based on plasma level of vitamin D3, diabetic subjects were divided into two separate treatment groups (with and without vitamin D3 deficiency) and then above-mentioned factors were compared between these two groups. Afterward, in group with vitamin D3 deficiency, treatment by vitamin D3 triggered (50000 unit per week for eight weeks orally) until plasma level of vitamin D3 reached above 30 ng/mL. Then, treatment continued by vitamin D3 (50000 Unit per week orally) and calcium (1.5 g/day PO) until 60 days. Finally, the patients were evaluated about fasting blood glucose, HbA1c, HDL, LDL and blood pressure.
Results: In total, 187 subjects (99 men and 88 women) were evaluated in this study. Total hypovitaminose incidence was 0.65% which was higher in subjects with higher body mass index (BMI). Serum content of vitamin D3 and calcium, significantly changed the values of fasting blood sugar (FBS), HbA1c, HDL and TG, but has no significant effects on other factors.
Conclusion: Our results clearly revealed that hypovitaminose vitamin D3 is one of the main factors that can leading to rise in plasma glucose and dyslipidemia occurrence. Also, our data are demonstrated that treatment by vitamin D3 and calcium can modify fasting blood glucose and dyslipidemia in type 2 diabetes mellitus subjects.

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: Labor induction is one of the most public ways carried out global for delivering mothers. The aim of labor induction is to encourage uterine contractions before the spontaneous onset of labor, resultant in vaginal delivery misoprostol is used off-label for a variety of indications in the practice of obstetrics and gynecology, including medication abortion, medical management of miscarriage, induction of labor, cervical ripening before surgical procedures, and the treatment of postpartum hemorrhage. Regarding the importance and lack of similar researches in Iran, this research was done to compare the efficacy of buccal and sublingual misoprostol for labor induction in pregnant women.
Methods: This study was conducted as a randomized double-blind clinical trial from March 2017 to February 2018. In this survey, 200 women were randomly assigned to receive 50 µg buccal misoprostol and sublingual (100 buccal and 100 sublingual) in Kosar Hospital, Qazvin University of Medical Sciences, Iran. The maternal and fetal complications, Bishop score, and time of pain onset and its interval with labor were monitored in two groups and the findings were analyzed.
Results: Research variables were age, gestational age, BMI, number of previous pregnancy, neonatal weight, total dose, Bishop score 1, Bishop score 6, oxytocin, and delivery type. The results showed that there were no differences between Bishop score 6 (P=0.07), and 1 (P=0.36), total dose (P=0.58), neonatal weight (P=0.43), number of pregnancy (P=0.67), BMI (P=0.67), and pregnancy weak (P=0.108) of sublingual group and buccal group. About 43 patients (43%) in buccal and 64 (64%) in sublingual group had vaginal delivery (P=0.05). The frequencies of maternal and fetal complications were similar between two groups.
Conclusion: It can be concluded that there is no difference between efficacy of sublingual and buccal misoprostol in pregnancy results, maternal, and fetal complications, however, it seems that the sublingual group is more effective than buccal group due to the significant amount of vaginal delivery, achieving vaginal delivery in less than 24 hours, and less need for oxytocin.

Abstract
The cartilage is a connective tissue that, due to the strength of its extracellular matrix, allows the tissue to tolerate mechanical stress without undergoing permanent deformation. It is responsible for the support of soft tissues and due to its smooth surface and elasticity, gives the joints the ability to slip and bend. excessive weight, excessive activity, or trauma can all cause cartilage to injury. The injury can lead to swelling, pain and varying degrees of mobility loss. The process of repairing musculoskeletal (orthopedic) injuries has led to problems in the medical field, which can be attributed to the inherent weakness of adult cartilage tissue. Therefore, this necessitates research focused on the development of a new restructuring strategy by combining chondrocytes or stem cells with scaffolds and growth factors to address these problems. Correspondingly, the recent tissue engineering strategies strongly support the simultaneous use of stem cells, scaffolds and growth factors. It has also been observed that due to the relatively low proliferation of transplanted chondrocytes, new cartilage models construction have examined the use of adipose-derived stem cells. Mature adipose tissue is produced as an important source of multi-functional stem cells that can be easily separated from the stromal vascular fraction (SVF) by adipose liposuction digestion. The adipose-derived stem cells are easily accessible without any serious complications and have the power to differentiate into several cell lines, including chondrocytes as well as, they evidence self-renewal when trapped in gel scaffolds such as collagen. Also, recent studies demonstrate some of the mechanisms involved in the process of making cartilage of adipose-derived stem cells in vitro and their restorative ability in bio-engineered scaffolds in the presence of growth factors. In addition, the important role of non-encoding mRNA molecules (miRNAs) has been identified in the process of chondrogenic differentiation of adipose-derived stem cells. Furthermore, in several studies, the effect of several miRNAs has been confirmed on the regulation of the cartilage differentiation of the adipose-derived stem cells and has also been associated with effective results. In this article, we will present an overview of the advance in adipose-derived stem cells application in cartilage regeneration.

Abstract
Background: Metabolic syndrome (MetS) is characterized by a combination of cardio-metabolic risk factors. Given that genetic factors have been shown to contribute to individual susceptibility to MetS, the identification of genetic markers for disease risk is essential. Recent studies revealed that rs780094 and rs1260326 of glucokinase regulatory gene (GCKR) are associated with serum triglycerides, plasma glucose levels and metabolic syndrome. The aim of this study was to investigate associations of GCKR gene variants with metabolic syndrome and its components.
Methods: This case-control study was conducted from April to August 2017. In this study, 8710 adults (3522 males and 5188 females), over 19 years, were randomly selected from the Tehran Lipid and Glucose Study (TLGS) population. Based on joint interim statement (JIS) criteria, the subjects were divided into two groups: case and control. Genotyping was performed by HumanOmniExpress-24 v1.0 BeadChips (Illumina, San Diego, CA, USA).
Results: Allele frequencies were in conformity with Hardy-Weinberg equilibrium. Comparisons of allele frequencies by the Chi-square test revealed that frequencies of TT genotype of both polymorphisms were significantly higher among patient group than healthy group. Logistic regression analysis with adjustment for age, gender and CRP revealed that the GCKR polymorphisms (rs1260326: odds ratio 2.7, 95% CI 1.6-4.6, rs780094: odds ratio 2.5, 95% CI 1.5-4.2) were significantly associated with MetS. Frequency of TT genotype was more in persons who had C-reactive protein (CRP) levels above 3 mg/l. The minor T allele of both polymorphisms was significantly associated with increases in the blood serum concentration triglyceride and to a decrease in fasting plasma glucose levels.
Conclusion: The results of our study indicated that, rs780094 and rs1260326 common polymorphisms of the GCKR gene were associated with serum triglycerides levels, fasting plasma glucose levels, and metabolic syndrome in a sample of the Tehranian population (TLGS), as it was already confirmed the inverse effect of this polymorphisms on triglycerides and glucose levels in previous studies.

Abstract
Background: There are contradictions in the role of genetic variations and food group intake on metabolic syndrome (MetS). This study was aimed at examining the interaction between food groups and CCND2 rs11063069, ZNT8 rs13266634 and MC4R rs12970134 polymorphisms, regarding MetS and its components.
Methods: In this matched nested case-control study (2006-2014), the data of 1634 (817 pairs) case and controls were selected among participants of the Tehran Lipid and Glucose Study (TLGS). The cases and controls were matched by age, sex and number of follow-up years. Dietary intakes were assessed using a valid and reliable food frequency questionnaire. Polymorphisms were genotyped.
Results: A significant interaction was observed between rs12970134 and green vegetable, read meat, and soft drink, in relation to the risk of low high density lipoprotein cholesterol (HDL-C), high triglyceride (TG) and high fasting blood glucose (FBG), respectively (P<0.05). The consumption of vegetables altered the effect of rs11063069 on MetS. Among G allele carriers, being in the highest quartiles of vegetables intake had a decrease risk of MetS, compared to those in the lowest quartile (P=0.007), but this trend was not observed in AA genotype carrier. There was also a significant interaction between rs13266634 and salty snack and fish intakes, in relation to the risk of abdominal obesity (P<0.05). Increasing salty meals by CT+TT genotypes carriers increased the odds ratio of abdominal obesity, while in the CC genotype, this increase was not observed. A significant interaction was also observed between rs11063069 with other vegetables, red-yellow vegetable and fruit intake respectively, regarding the risk of high FBG, low HDL-C and high blood pressure (P<0.05).
Conclusion: The present study demonstrates the interaction between food groups and MC4R, ZNT8 and CCND2 polymorphisms. To reduce the risk of MetS, high risk allele carriers of rs12970134 must avoid meat consumption, while in high risk allele carriers of rs11063069 and rs13266634, vegetables and fish should be consumed.

Abstract
Background: Nutrition education and introduction of procedures for choosing healthier food have an important role to reduce the rate of non-communicable diseases. It was shown the amount of risk factors of non-communicable diseases such as energy, salt, sugar, fat and trans fatty acid on the traffic light of food labelling. The status of risk is presented through three colors of red, yellow and green that are the signs of risk, precautious and safe use of food. The object of this study was to evaluate the influence of education on the knowledge, attitude and practices of Isfahan University of Medical Sciences students to the traffic light on food labeling.
Methods: This project was an empirical study performed by random sampling of 379 students of nine schools in Isfahan University of Medical Sciences from January 2017 to March 2018. The knowledge, attitude and practices of students toward the traffic light were assessed by self-administered and structured questionnaire. Education was performed face to face with the usage of pamphlet. In the period of three to six months, questionnaires were refilled out by students to determine knowledge, attitude and practice. Descriptive statistics were calculated using SPSS in mean± SD. Paired t-test was performed to assess the influence of education in total score of knowledge, attitudes and practices in test-retest. P value was considered less than 0.05 as statistically significant.
Results: Before education, the average of scores for knowledge, attitude and practice was 1.12±0.84, 14.44±4 and 2.25±2.2, respectively. Afterwards, the scores were increased to 11.72±0.75, 18.67±3.18 and 17.69±4.7 after education. Significant difference was observed in the scores of knowledge, attitude and practice of students before and after education (P<0.05).
Conclusion: Education of traffic light had a significant role in the improvement of knowledge, attitude and to some extent of practice of students in selection of healthier food.

Abstract
Background: Although significant advances have been made in scientific and medical technology, but the rate of medical complaints has also risen. The purpose of this study was to investigate the effect of handling of medical malpractice cases in the hospital complaints committee on the reduction of patient complaints to law enforcement authorities.
Methods: In this descriptive study, patients complained about ophthalmology from April 2005 to December 2005 at Farabi Hospital, Tehran, were evaluated. The complainant's patients, if confirmed by the trusted doctors, were invited to complaints committee, and the subject of the complaint was examined and tried to obtain patient satisfaction.
Results: A total of 87 patients complained to ophthalmologists completed a complaint form 71 (81.7%) of the cases were male. Statistically, the number of complaints was significantly lower in those with lower education (P=0.02). The prevalence of primary disease, 52 cases (59.8%) was cataract and 14 cases (16%) due to refractive errors and refractory surgery. In the examination of complaints by trusted doctors in the hospital, 11 cases of ophthalmologic error were identified, with a mantle rate of 12.6%, and the cases were reviewed by the complaints committee. Of the cases of complained that confirmed by the committee, only one person sued the law enforcement, which represented 9% of the defaulted item. These statistics showed a significant decline compared to the past year at the same center, and the percentage of defaults to law enforcement was 37.5% (P<0.05).
Conclusion: Establishing committees to handle complaints of ophthalmologic failures in hospitals and providing a clear and honest atmosphere to hear the subject of complaints by patients and their companions, and then trying to get patients' satisfaction and helping them continue their treatment can lead to reduced complaints of patients to the authorities Legal, like forensics medicine department and medical council.

Abstract
Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive age women. The prevalence of PCOS among Iranian women is 14.6% based on the Rotterdam definition. PCOS can increase the risk of chronic metabolic complications. Metabolic syndrome (MetS) is one of the most important of them. Insulin resistance is fundamental in PCOS and MetS pathophysiology. MetS is a collection of chronic metabolic derangements, which promotes the risk of serious diseases such as cardiovascular disturbances and diabetes. The quality of diet is inversely correlated with obesity, which is one of the consequences of PCOS and it is a risk factor for metabolic syndrome. As the first study, the present study aimed to compare the dietary intake of macronutrients in PCOS women with and without MetS.
Methods: In this nested case-control study, the convenience sampling method was used to select participants. The case group included 14 PCOS patients with MetS and the control group included 28 PCOS patients without MetS. The investigated macronutrients included fats (total fat, saturated fatty acids, mono and polyunsaturated fats, trans fatty acids), carbohydrate, protein, and fibers (total and soluble). The dietary intake assessment was carried out by a 168-item semi-quantitative food frequency questionnaire (FFQ). This study was performed on Arash Women's Hospital under support of Tarbiat Modares University, Tehran, Iran, from August 2014 to September 2015.
Results: Dietary intake of total fat was significantly higher in PCOS women with MetS than the control group (P<0.001, 146.62±45.17 vs. 59.91±32.79 g/d). Dietary intake of saturated fatty acids (P=0.004, 11.44±11.08 vs. 19.73±6.76 g/d), monounsaturated fats (P<0.001, 14.15±12.66 vs. 26.16±7.76 g/d), polyunsaturated fats (P=0.002, 9.02±9.18 vs. 17.22±6.45 g/d), carbohydrate (P<0.001, 182.34±121.08 vs. 365.64±77.11 g/d), protein (P=0.001, 42.74±42.85 vs. 78.06±24.04 g/d), total fiber (P<0.001, 17.77±15.09 vs. 35.97±22.64 g/d) was significantly lower in PCOS women with MetS than the control group. All results are expressed in terms of grams consumed per day.
Conclusion: Our results demonstrated that dietary intake of macronutrients was significantly different in polycystic ovary syndrome patients with and without metabolic syndrome.

Abstract
Background: Amphotericin B is one of the most useful therapeutic modalities for the treatment of patients with invasive fungal infections, in spite of serious side effects, namely kidney injury, electrolyte imbalances, and infusion-related reactions. The goal of this study was to assess the different aspects of premedication practice and the incidence and types of infusion-related reactions in patients receiving amphotericin B.
Methods: This observational study was performed on 70 hospitalized patients who received amphotericin B in different departments of two university hospitals, affiliated to Isfahan University of Medical Sciences, Isfahan, Iran, from January 2017 to February 2018. Information on physicians’ performance regarding premedication administration for amphotericin B, including the types and doses of medications administered prior to amphotericin B infusion, as well as patients’ clinical data including infusion-related side effects were collected and then analyzed in comparison with the standard practice guidelines.
Results: The study population consisted of 70 patients with the mean age of 51.6±18.3 years, who received amphotericin B for 8.2±3.5 days. From 70 evaluated patients, 21 patients (30%) had encountered the infusion-related reactions, including chills, fever, urticaria, headache, and hypotension. These side effects were evident in 19 patients (27%) who received no premedication and 2 patients (3%) who received only one drug as premedication, before amphotericin B administration. Twenty patients (28%) experienced chills, fever and headache, while 7 patients (10%) had nausea and vomiting during amphotericin B infusion. Hydrocortisone 50-200 mg, was the most prescribed agent for premedication (in 67% of patients), while chlorpheniramine 10 mg (in 50% of patients) and promethazine 10 mg (in 35% of patients) were the second and third prescribed ones, respectively.
Conclusion: In this study, the patients who received no or only one drug as premedication experienced infusion-related side effects. This emphasizes the necessity for standard premedication practices to prevent this type of adverse reactions. Considering the higher price of liposomal form of Amphotericin-B, if prescribed correctly, even the conventional form would be an effective and tolerable treatment for invasive fungal infections.

Abstract
Background: Changing the mental structure of students and identifying creativity inhibitors are essential for academic survival and the pursuit of innovation. This study aimed to identify the inhibitory cognitive factors in medical students.
Methods: This study was a directional qualitative content analysis that conducted based on scientific literature review and opinions of experts in a semiformal expert panel by using semi-structured interviews ranging from 20 to 70 minutes from February 2015 to October 2016. Seventeen talented students were interviewed and conversations were recorded with a digital voice recorder at the Exceptional Talent Development Center (ETDC). The extraction and content analysis was continuously done by listening and writing through several times. The students were in various medical disciplines, and most of them were first rank students in scientific performance and they were collaborating with ETDC.
Results: The inhibition variables of creativity were classified in the four main subcategories according to the semantic relationship and after compression, these classes of inhibitory factors included: teacher-related inhibitors, teaching and assessment methods related inhibitors, student barriers and inhibitors of the university's educational system. Finally, 10 codes were extracted from the 4th categories, which were mentioned as inhibitory variables of creativity. The teachers' lack of enthusiasm with the new ideas, the lack of creativity in the academic context and the lack of motivation among the students were the main inhibitors of creativity that were extracted from interviewing with talented students.
Conclusion: In this study, the most important cognitional inhibitory factors in creativity promotion were the inhibitors related to the teacher’s character and his attitude to creativity, methods of teaching and the university environment. Planning for the removal of these barriers in medical students recommended.

Abstract
Background: Helicobacter pylori (H. pylori) is a highly prevalent, serious and chronic infection. It been associated causally with a diverse spectrum of gastrointestinal disorders including chronic gastritis, peptic ulcer disease, gastric adenocarcinoma. We conducted a study to Evaluation of the role of breastfeeding and breast milk on the colonization of H. pylori in the gastrointestinal tract of 2-24 month old.
Methods: This cross-sectional study was performed on 92 children referred to Ali Asghar Hospital of Iran University of Medical Sciences for two years (from July 2015 to June 2017). At first, a questionnaire was recorded by the neonatal specialist including demographic and clinical characteristics of the infants. Stool samples were taken from infants at 2, 6, 12, and 24 months of age. We used the H. pylori stool antigen test to detection infection in the selected group of children. H. pylori status was evaluated by an enzyme-linked immunosorbent assay (ELISA).
Results: In the study of breastfeeding at 12 months of age, 51.1% were fed only dry milk and 28.3% were breastfed only. At 24 months, 22 infants (24%) were breastfed with supplemental feeding and 54 children (58.7%) were formula-fed only and 8 children (8.7%) were breastfed only. In our study, the prevalence of H. pylori in infants of Tehran, at 2, 6, 12, and 24 months, were 0%, 6.5%, 15.21%, and 34.4%, respectively. Of the 92 children studied, during the first month, 25 children (27.2%) only formula-fed and 49 children (53.3%) were breastfed only and (19.6%) 18 infants were breastfed with dry milk. The prevalence of H. pylori infection was 28.3%. The prevalence of H. pylori infection was 20% in the breastfeeding group and 44% in the infant dry milk feeding group. The prevalence of H. pylori antigen was greater than 12 IU/ml in infants 2, 6, 12, and 24 months of age, including 19.92 (20.6%), 19.92 (20.6%), 24.92 (26.1%) and 21.92 (22.8%), respectively.
Conclusion: According to the findings of the article, breastfed children compared to formula-fed children were less infected by Helicobacter pylori.
