Page 1BackgroundThe purpose of this study was to evaluate the infl uence of ejection fraction (EF) on peak aortic time (PAT) and peak aortic enhancement (PAE) during coronary computed tomography angiography (CTA).Materials And MethodsOne-hundred and twenty patients (64 men, 56 women) underwent measurement of coronary CTA with a measurement of EF within 3 months of coronary CTA.Pearsons correlation coeffi cient analysis was used to investigate the relationships between EF, PAT and PAE, and peak attenuation of all coronary arteries.ResultsTh e range of EF was (25%70%) (mean: 55 ± 7.7). The range of PAT and PAE of ascending aorta on bolus test was 1331 s (mean: 19.3 ± 2) and 153435 HU (mean: 235 ± 40.6), respectively. Mean peak attenuation of ascending aorta, right coronary artery, left coronary artery, left circumfl ex artery, and left anterior descending were (561 ± 119), (476 ± 109), (505 ± 108), (467 ± 113),and (473 ± 104), respectively. Th ere was a negative correlation between EF and PAT (r =?0.266, P = 0.003); however, there was no signifi cant correlation between EF and PAE (r = ?0.027, P = 0.767).In addition, there was no signifi cant correlation between EF and the peak attenuation of coronary arteries.ConclusionPAT was related to EF, but there was no relationship between PAE and EF.
One of the explanation is that the left ventricular EF used for our study was assessed with echocardiography which is used roughlyestimation of EF with interval of 5%10% and may cause confounding results.Keywords: Computed tomography, contrast enhancement, coronary artery, ejection fraction -
Page 3BackgroundThe celiac axis, superior mesenteric artery (SMA), and hepatic artery are the most important branches of abdominal aorta due to their vascularization field. The aim of our study was to evaluate the prevalence of different anatomical variation of celiac axis, SMA, hepatic artery, and its branches with multidetector computed tomography (MDCT) angiography of upper abdomen arteries.Materials And MethodsMDCT of 607 kidney donor and traumatic patients that referred to MDCT unit at Al Zahra Hospital in Isfahan from 2012 to 2015 were retrospectively evaluated. We participated subjects without any history of abdominal vascular surgery and hepatic or pancreatic surgery. Computed tomography images of the patient were obtained with 64-row MDCT scanner and anatomical variations were analyzed.ResultsThree hundred and eighty-eight (63.9%) of the 607 patients had classic arterial anatomy [Figure 1], and 219 (36.1%) patients had variant types. The most common type of variation was the origin of the right hepatic artery (RHA) from SMA (9.6%), and the next common variation was the origin of the left hepatic artery (LHA) from the left gastric artery (6.9%). Variations in the origin of the common hepatic artery (CHA) were seen in 16 (2.6%) patients. Buhler arc was identified in two patients. The RHA originated from the celiac axis in 11 (1.8%) patients and from the aorta in 8 (1.3%) patients. Trifurcation of CHA into gastroduodenal artery, RHA, and LHA was detected in 11 (1.8%) patients.ConclusionThe results of the present study showed that anatomical variation occurs in a high percentage of patients. Detection of these variations can guide surgical and radiological interventional planning.Keywords: Major branches of abdominal aorta, multidetector computed tomography angiography, normal variation, prevalence

Page 4Background:Myocardial infarction (MI) is one of the major causes of death and disability worldwide which can reduces quality of life in patients. Some disabilities are depression and anxiety which delay returning to work The aim of this study was to evaluate the effect of illness perception focused intervention on quality of life, anxiety and depression in MI patients.
Material andMethodsA randomized controlled trial study of 48 recently hospitalized MI patients was conducted (24 in intervention group and 24 in control group).Intervention group were trained to understand the disease by a mental health counselor in three half an hour sessions for 3 consecutive days. Data were collected from 3 questionnaires (Hospital Anxiety Depression Scale (HADS), The World Health Organization Quality of Life Questionnaire (short form) and Illness Perceptions Questionnaire Brief (IPQ-B)at admission, 1.5 and 3 months post-discharge. Statistical analysis used: Data were analyzed with ANOVA Repeated Measure.ResultsThe mean duration of returning to work was 28.7 ± 8.1 days in intervention groups and 46± 7.6 days in control group which was statistically significant (PConclusionTraining MI patients to understand the disease in three half an hour sessions for 3 consecutive days can decrease the duration of returning to work, anxiety and depression and increase illness perceptions which can make better outcome.Keywords: Myocardial infarction, Illness perceptions, Anxiety, Depression, quality of life -
Page 5BackgroundPreterm labor (PTL) is the main challenge in prenatal health care, leads to high rate of mortality and increases cost of health services. To evaluate the preterm delivery (PTD)?related risk factors, we decided to measure nitrite oxide metabolites and cervical length (CL) as the diagnostic and predictive tools for PTD in women and response to tocolytic therapy.Materials And MethodsIn this casecontrol study, sixty women of 1835 years with first pregnancy during the 2434 gestational weeks with PTL in case group admitted to the delivery section of Beheshti Hospital, Isfahan, Iran were included. Sixty women in control group have the same specifications. NO and CL level were assessed, and the collected data were analyzed by SPSS software,version 20 and MedCalc software, version 15.1.ResultsThe two groups were similar regarding maternal and gestational age (P > 0.05).Lower level of NO was observed in PTL women with a mean of 35.30 ± 8.27 ?mol/L compared to the normal gestation group with a mean of 39.05 ± 10.17 ?mol/L (P = 0.035). In addition, the diagnostic accuracy of both PTL?predicting factors was determined (NO ?31, sensitivity 99.7%, specificity 82.5% and CL ?22, sensitivity 80%, specificity 99.9%).ConclusionAs the previous investigations stated, it can be claimed that NO might be the reliable marker for predicting the PTL, and administration of NO synthesis could be a candidate for the future therapeutic target.Keywords: Cervical length, nitrite oxide, preterm delivery, preterm labor

Page 6BackgroundHealth?related quality of life (HRQL) and voice handicap index (VHI) of laryngectomies seem to be relevant regarding voice rehabilitation. The aim of this study is to assess the impact on HRQL and VHI of laryngectomies, following voice rehabilitation.Materials And MethodsA retrospective study done at the Ear, Nose, and Throat Department of the Emergency County Hospital. Sixty?five laryngectomees were included in this study, of which 62 of them underwent voice rehabilitation. Voice handicap and QOL were assessed using the QOL questionnaires developed by the European Organisation for Research and Treatment of Cancer (EORTC); variables used were functional scales (physical, role, cognitive, emotional, and social), symptom scales (fatigue, pain, and nausea and vomiting), global QOL scale (pain,swallowing, senses, speech, social eating, social contact, and sexuality), and the functional, physical, and emotional aspects of the voice handicap (one?way ANOVA test).ResultsThe mean age of the patients was 59.22 (standard deviation = 9.00) years. A total of 26 (40%) patients had moderate VHI (between 31 and 60) and 39 (60%) patients had severe VHI (higher than 61). Results of the HRQL questionnaires showed that patients who underwent speech therapy obtained better scores in most scales (P = 0.000). Patients with esophageal voice had a high score for functional scales compared with or without other voice rehabilitation methods (P = 0.07), and the VHI score for transesophageal prosthesis was improved after an adjustment period. The global health status and VHI scores showed a statistically significant correlation between speaker groups.ConclusionThe EORTC and the VHI questionnaires offer more information regarding life after laryngectomy.Keywords: Quality of life, voice handicap index, voice rehabilitation

Page 7BackgroundEchinococcosis is a parasitic disease with worldwide distribution which is caused by the tapeworms Echinococcus granulosus. Diagnosis of the disease relies on imaging techniques, but the techniques are not able to differentiate the cyst from benign or malignant tumors; hence, appropriate serologic methods are required for the differential diagnosis of the infection.Materials And MethodsIn this investigation, different sheep hydatid cyst antigens probed with thirty sera of patients with hydatid cyst and also thirty human normal sera using Western immunoblotting technique. Considering results of surgery as gold standard, sensitivity and specificity of Western blotting was estimated.ResultsSera of 29, 26, and 16 patients with hydatid cyst reacted with specific bands of hydatid cyst fluid (HCF), protoscolex crude antigen, and cyst wall crude antigen, respectively. However, none of the normal human sera reacted with those specific bands.ConclusionA 20 kDa band of sheep HCF is an appropriate antigen for serodiagnosis of hydatid cyst infection.Keywords: Antigen, cyst wall, hydatid cyst fluid, protoscolex, Western immunoblottin

Page 8BackgroundPreeclampsia complicates up to 3% of pregnancies in developing countries. Endothelial dysfunction plays an important role in pathogenesis of preeclampsia. In this study, we aim to evaluate the effect of low?dose aspirin on endothelial dysfunction in preeclamptic patients.Materials And Methodsin this triple?blind randomized clinical trial, enrolled patients were divided randomly into two groups. Acetylsalicylic acid (ASA) 80 mg or placebo will be taken daily by oral administration from the initiation of diagnosis until 2 months after delivery. Every patients flow?mediated dilation (FMD) were evaluated at the beginning of study and 2 months after delivery with the same experienced operator at a same period of the time (35 pm) by high?resolution B?mode ultrasonographic. T?test or MannWhitney test was used in the comparison of means between the intervention and placebo groups. To compare FMD in each group, before and after the intervention, paired t?test was used.ResultsMean value of FMD in intervention (9.61 ± 5.58) and control group (9.40 ± 4.33) have no significant differences before drug consumption (P = 0.089). FMD in intervention group significantly increased after ASA consumption ([9.61 ± 5.58 vs. 13.65 ± 7.91] [P = 0.044]).ConclusionIncrease mean of FMD in intervention group shows that this supplement can improve endothelial function.Keywords: Acetylsalicylic acid, endothelial dysfunction, preeclampsia

Page 9BackgroundThis study aimed to compare the percentage of detection of periarthritis in patients with rheumatoid arthritis using clinical examination and ultrasound methods.Materials And MethodsThis study is a cross?sectional study which was conducted in Al?Zahra Hospital (Isfahan, Iran) during 20142015. In our study, ninety patients were selected based on the American College of Rheumatology 2010 criteria. All patients were examined by a rheumatologist to find the existence of effusion, and the data were filled in the checklist. The ultrasonography for detecting effusion in periarticular structures was done by an expert radiologist with two methods, including high?resolution ultrasonography and power Doppler. The percentage of effusion existence found by physical examination was compared by sonography, and the Chi?square and t?tests were used for data analysis.ResultsThe percentage of effusion found in areas with physical examination by rheumatologist was lower than the frequency distribution of effusions found by sonography (8.3% VS 14.2%) (PConclusionThe percentage of periarthritis detection by ultrasonography and power Doppler sonography was higher than clinical examination. Hence, the ultrasonography is more accurate than physical examination.Keywords: Periarthritis, rheumatoid arthritis, ultrasonography

Page 10BackgroundProper sleep is essential for the development of premature infants. Infants, during hospitalization, might suffer from inappropriate postures and insufficient sleep hours. To compare the daily sleep quantities of premature infants in flexed (facilitated fetal tucking) posture and extended (free body) posture. This study is a randomized clinical trial which was conducted in neonatal ward of Al?Zahra Teaching Hospital of Tabriz, Iran, 2015. Thirty?two premature infants with the age range of 3336 weeks were selected for the study.Materials And MethodsEvery infant was studied for 4 days in a sequential format. Every infant was studied for 4 days and in a 12?h period every day (8 a.m8 p.m). Each day, an infant was randomly put in one of the four statuses, namely, free body posture in the supine position, free body posture in the lateral position, facilitated fetal tucking in the supine position and facilitated fetal tucking in the lateral position. Films were recorded in the 12?h period (8 a.m8 p.m). SPSS Software (version 13) was used for data analysis.ResultsThe results showed that about the main effect of posture on sleep variable, there was a statistically significant difference (P = 0.003). In addition, about the main effect of position on sleep variable; there was a statistically significant difference (P = 0.002). Meanwhile, there was no significant interaction effect between the posture and position for the daily sleep duration (P = 0.746). Daily sleep duration of the infants in flexed (facilitated fetal tucking) posture and lateral position is longer than that of the infants in extended (free body) posture and supine position.ConclusionsDaily sleep duration in the infants experiencing flexed posture and lateral position at rest is longer. Moreover, it decreases wakefulness time of the premature infants.Keywords: Facilitated fetal tucking, lateral position, posture, premature infants, supine position

Page 11BackgroundQuality of life in patients represents an important area of assessment. However, attention to health professionals should be equally important. The literature on the quality of life (QOL) of emergency physicians is scarce. This pilot study investigated QOL in emergency physicians in Germany.Materials And MethodsWe conducted a cross?sectional study from January to June in 2015.We approached the German Association of Emergency Medicine Physicians and two of the largest recruitment agencies for emergency physicians in Germany and invited their members to participate. We used the WHO Q?BREF to obtain QOL scores in four domains that included physical, mental, social, and environmental health.ResultsThe 478 German emergency physicians included in the study held board certifications in general medicine (n = 40; 8.4%), anesthesiology (n = 243; 50.8%), surgery (n = 63; 13.2%), internal medicine (n = 81; 17.0%), or others (n = 51; 10.7%). The women surveyed tended to report a better QOL but worse general health than the men. Regarding specific domains, women scored worse in physical health, particularly energy during everyday work (relative risk ratio [RRR]: 1.98 [1.213.24]). Both men and women scored worse in psychological health than general health, particularly young women. Women were also more likely to view their safety (RRR: 1.87 [1.073.28]) and living place (RRR: 2.51 [1.105.73]) as being poor than their male counterparts.ConclusionQOL in German prehospital emergency care physicians is satisfactory for the included participants; however, there were some negative effects in the psychological health domain. This is particularly obvious in young female emergency physicians.Keywords: Clinician, emergency care, mental health, quality of life

Page 12BackgroundIncreased life expectancy and the growing phenomenon of aging can lead to increased burden of Chronic Diseases (CDs) which adversely affects the overall health of elderly, their sexuality in particular. Sexual life of aged population is overlooked in many of the societies. In the present narrative review, we aim to assess the impact of CDs on sexual function of elderly people.Materials And MethodsWe used internet databases including Pub Med, Embase, ISI Web of Science, Google Scholar, SID, Iran Medex, Magiran, IPPF, and UNFPA without time limit. Ninety eight out of 174 relevant articles were selected which met the inclusion criteria: those articles were research-based in English or Persian (original or review articles), and text books; specified one or more chronic diseases and sexual function of the subjects; elderly people over the age of 60, men and women; coordination between articles and research goals. We excluded qualitative and case studies. We reported the most related CDs with sexual function in literature review and used the biological and psychological impact of the CDs on sexual function of aged population based on the conceptual model of Verschuren et al (2010).ResultsThe results of the studies were classified into the themes including physical, psychological, and cultural and social. Diabetes, cardiovascular, cancerous and chronic respiratory diseases and also some medications can reduce sexual capacity and desire in particular resulting in negative impact on the quality of elderly sexual life. CDs may influence sexual expressions and responses which adversely affect ones mood and energy so that can cause depression and grief as well as loss of self-confidence, self-esteem, and self-concept in aged adults. The factors affecting sexuality of an elderly with CDs include cultural and mythical beliefs about age and illnesses, fear, and embarrass of changed physical appearance. The research conducted among elderly population examining the adverse influence of CDs on aged peoples sexual life in general, sexual function and performance, and intimate interaction.ConclusionIt is considered that programs on sexual health needs of aged population for the health care workers can prove beneficial in improving sexual health.Keywords: Ageing, Chronic Diseases, Sexuality, Review

Page 13Currently, gastrointestinal (GI) dysfunctions in Parkinsons disease (PD) are well?recognized problems and are known to be the initial symptoms in the pathological process that eventually results in PD. Many types of PD?associated GI dysfunctions have been identified, including weight loss, nausea, hypersalivation, dysphagia, dyspepsia, abdominal pain, intestinal pseudo?obstruction, constipation, defecatory dysfunction, and small intestinal bacterial overgrowth. These symptoms can influence on other PD symptoms and are the second mostsignificant predictor of the quality of life of these patients.Recognition of GI symptoms requires vigilance on the part of clinicians. Health?care providers should routinely ask direct questions about GI symptoms during office visits so that efforts can be directed at appropriate management of these distressing manifestations. Multiple system atrophy (MSA) and progressive supranuclear palsy are two forms of neurodegenerative Parkinsonism. Symptoms of autonomic dysfunctions such as GI dysfunction are common in patients with parkinsonian disorders. Despite recent progress in the recognition of GI dysfunctions, there are a few reviews on the management of GI dysfunction and GI symptoms in idiopathic Parkinsonism. In this review, the clinical presentation, pathophysiology, and treatment of each GI symptom in PD, MSA, and prostate?specific antigen will be discussed.Keywords: Multiple system atrophy, Parkinson's disease, progressive supranuclear pal

Page 14BackgroundAlthough several studies have investigated the association between ovarian cancer risk and nonisoflavone flavonoids intake, these findings are inconsistent. This systematic review of published epidemiological studies was conducted to summarize and clarify the evidence on the association between ovarian cancer incidence and nonisoflavone flavonoids intake.Materials And MethodsPubMed, Scopus, Google Scholar, and EMBASE databases were searched based on MeSH term (ovarian neoplasm in combination with flavonoids) to identify related English and non?English papers published up to June 2016. We summarized the results of the relevant studies in this review.ResultsIn total, seven studies (four with cohort and three with casecontrol design) included in this review. The results of conducted cohort studies show no relation between ovarian cancer risk and total nonisoflavone flavonoids intake, and only one study reported a significant reduction between ovarian cancer incidence and kaempferol and luteolin intake. Similar to those in the cohort studies, also in casecontrol studies, no association was found between total nonisoflavone flavonoids intake and ovarian cancer risk, just an inverse association between flavonols intake and ovarian cancer was reported.ConclusionSeveral studies investigated the relation of nonisoflavone flavonoids intake and ovarian cancer risk; none of them reported any association for total nonisoflavone flavonoids intake, but some reported an inverse association between certain subclasses or individual flavonoids. These findings are limited, and there is a need for further and more accurate researches to be confirmed.Keywords: Flavanones, flavonols, nonisoflavone flavonoid, ovarian neoplasm
