Enterococci are important pathogens in nosocomial infections. Various types of antibiotics, such as aminoglycosides, are used for treatment of these infections. Enterococci can acquire resistant traits, which can lead to therapeutic problems with aminoglycosides. This study was designed to identify the prevalence of, and to compare, the aac(6')-aph(2") and aph(3)-IIIa genes and their antimicrobial resistance patterns among Enterococcus faecalis and E. faecium isolates from patients at Imam Reza hospital in Kermanshah in 2011 - 2012. One hundred thirty-eight clinical specimens collected from different wards of Imam Reza hospital were identified to the species level by biochemical tests. Antimicrobial susceptibility tests against kanamycin, teicoplanin, streptomycin, imipenem, ciprofloxacin, and ampicillin were performed by the disk diffusion method. The minimum inhibitory concentrations of gentamicin, streptomycin, kanamycin, and amikacin were evaluated with the microbroth dilution method. The aminoglycoside resistance genes aac(6')-aph(2") and aph(3")-IIIa were analyzed with multiplex PCR. The prevalence of isolates was 33 (24.1%) for E. faecium and 63 (46%) for E. faecalis. Eighty-nine percent of the isolates were high-level gentamicin resistant (HLGR), and 32.8% of E. faecium isolates and 67.2% of E. faecalis isolates carried aac(6')-aph(2"). The prevalence of aph(3")-IIIa among the E. faecalis and E. faecium isolates was 22.7% and 77.3%, respectively. Remarkably increased incidence of aac(6')-aph(2") among HLGR isolates explains the relationship between this gene and the high level of resistance to aminoglycosides. As the resistant gene among enterococci can be transferred, the use of new-generation antibiotics is necessary.

The improvement of technology has increased noise levels in hospital Wards to higher than international standard levels (35-45 dB). Higher noise levels than the maximum level result in patient's instability and dissatisfaction. Moreover, it will have serious negative effects on the staff's health and the quality of their services. The purpose of this survey is to analyze the level of noise in intensive care units and emergency wards of the Imam Reza Teaching Hospital, Mashhad. This research was carried out in November 2009 during morning shifts between 7:30 to 12:00. Noise levels were measured 10 times at 30-minute intervals in the nursing stations of 10 wards of the emergency, the intensive care units, and the Nephrology and Kidney Transplant Departments of Imam Reza University Hospital, Mashhad. The noise level in the nursing stations was tested for both the maximum level (Lmax) and the equalizing level (Leq). The research was based on the comparison of equalizing levels (Leq) because maximum levels were unstable. In our survey the average level (Leq) in all wards was much higher than the standard level. The maximum level (Lmax) in most wards was 85-86 dB and just in one measurement in the Internal ICU reached 94 dB. The average level of Leq in all wards was 60.2 dB. In emergency units, it was 62.2 dB, but it was not time related. The highest average level (Leq) was measured at 11:30 AM and the peak was measured in the Nephrology nursing station. The average levels of noise in intensive care units and also emergency wards were more than the standard levels and as it is known these wards have vital roles in treatment procedures, so more attention is needed in this area.

A series of court and tribunal decisions in the course of 2012 in Australia has highlighted the vulnerability of seriously ill patients to overtures and advertising by charismatic health practitioners offering panaceas of unproven efficacy. Drawing upon the findings of the Victorian Court of Appeal in relation to Noel Campbell, the Deputy State Coroner of Western Australia in relation to Helfried Sartori, and the Victorian Civil and Administrative Tribunal in relation to Reza Ghaffurian, it is argued that there is a strong public interest in the capacity for effective early intervention by government in relation to unscrupulous and unethical conduct by health practitioners, whether they are registered or unregistered. For Australia a constructive reform would be nationally consistent legislation to regulate unregistered health practitioners.

Introduction: Androgenetic alopecia (AGA) is one of the most common dermatologic disorders with a multifactorial etiology. Inflammatory activators such as Demodex infestation may play a role in the pathogenesis of some cases of androgenetic alopecia that do not respond to common treatments such as minoxidil and finasteride. The goal of this study is to evaluate the relationship between Demodex infestation and AGA. Materials and Methods: In this case-control study, 41 patients with AGA referred to the Dermatology Clinic of Imam Reza Hospital and 33 healthy individuals were evaluated as control. All of them were between 20 and 40 years old men. In order to identify Demodex infestation they were referred to the Parasitology laboratory. Results: Demodex was detected in 19.5% of patients and 15.2% of controls; therefore, there was no significant relationship between them statistically (P = 0.0787). Most of patients (85.4%) had greasy hair. The most common pattern of baldness was II degree in Hamilton scale. Conclusion: There is no relation between AGA and Demodex. PMID:19881989

Steroid administration during cardiopulmonary bypass is considered to improve cardiopulmonary function by modulating inflammations caused by bypass. This study was performed to compare effectiveness of preoperative and intraoperative methylprednisolone (MP) to preoperative methylprednisolone alone in post bypass inflammatory (IL-6) and anti-inflammatory (IL-10) factors. Fifty pediatric patients undergoing cardiopulmonary bypass surgery from August 2011 to 2012 in the cardiac surgery department of Imam Reza Hospital, the major center for CPB, in Mashhad, Iran were randomly assigned to receive preoperative and intraoperative MP (30 mg/kg, 4 hours before bypass and in bypass prime, number 25) or preoperative MP only (30 mg/kg, number 25). Before and after bypass, four and 24 hours after bypass, serum IL-6 and IL-10 were measured by ELISA. In both groups, no significant difference with variation of expression for IL-6 (inflammatory factor) and IL-10 (anti-inflammatory factor) in different times after bypass was observed. No significant difference in reducing post bypass inflammation between preoperative steroid treatment and combined preoperative and intraoperative steroid administration reported and they had the same effects.

Inadequate data are available on the global epidemiology of mucormycosis, mainly derived from the evaluation of specific population groups. Rhinocerebral mucormycosis is an invading and fatal mycosis, particularly among diabetic patients. In the present study, patients hospitalized in Imam Reza Hospital in Tabriz, from 2007 to 2017, were evaluated. The hospital information system (HIS) was used to collect the records of the patients. A total of 42 patients with a diagnosis of mucormycosis were included in the study, 40 cases (95%) of which had a diagnosis of the rhinocerebral form. Of these 40 patients, 21 (52.5%) and 19 (47.5%) were male and female, respectively. Seven cases (17.5%) of rhinocerebral mucormycosis were due to dental procedures. The most predisposing factor in the patients was diabetes with 36 (90%) cases. In our study, the role of tooth extraction in patients with uncontrolled diabetes was identified as an important factor. It may show the important role of dentists in preventing of the disease in diabetic patients. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Seventy five patients out of total 150 patients with signs and symptoms related to Vulvo Vaginal Candidiasis were treatedwith boric acidpowder everynight for a week and the remaining 75 patients received Fluconazole. The cure rate in first group was 46.7% but the cure rate in second group was 37.3%. The difference was not statistically significant (P>0.3). Difference between the efficacy of the two drugs was not significant either (P=0.47). The recurrence rate among patients in first group was 35% while it was 32% in second group. Their difference was not statistically significant (P=0.54). According to our findings, treatment of vaginal candidiasis with boric acid is as effective as fluconazole. The availability of boric acid and its relatively low cost suggests it as a safe and effective drug for treatment of candidiasis.

Benthic foraminifera species commonly outnumber planktic species in the type area of the Lower Miocene Qom Formation, in north central Iran, where it records the Tethyan link between the eastern Mediterranean and Indo- Pacific provinces. Because measured sections preserve very different sequences of first and last occurrences of these species, no single section provides a completely suitable baseline for correlation. To resolve this problem, we combined bioevents from three stratigraphic sections into a single composite sequence by constrained optimization (CONOP). The composite section arranges the first and last appearance events (FAD and LAD) of 242 foraminifera in an optimal order that minimizes the implied diachronism between sections. The composite stratigraphic ranges of the planktic foraminifera support a practical biozonation which reveals substantial local changes of accumulation rate during Aquitanian to Burdigalian times. Traditional biozone boundaries emerge little changed but an order of magnitude more correlations can be interpolated. The top of the section at Dobaradar is younger than previously thought and younger than sections at Dochah and Tigheh Reza-Abad. The latter two sections probably extend older into the Aquitanian than the Dobaradar section, but likely include a hiatus near the base of the Burdigalian. The bounding contacts with the Upper Red and Lower Red Formations are shown to be diachronous.

We aim to evaluate the impact of age and duration of symptoms on surgical outcome of the patients with cervical spondylotic radiculopathy (CSR) who had been treated by single-level microscopic anterior cervical discectomy and fusion (ACDF). We retrospectively evaluated 68 patients (48 female and 20 male) with a mean age of 41.2 ± 4.3 (ranged from 24 to 72 years old) in our Orthopedic Department, Imam Reza Hospital. They were followed up for 31.25 ± 4.1 months (ranged from 25 to 65 months). Pain and disability were assessed by Visual Analogue Scale (VAS) and Neck Disability Index (NDI) questionnaires in preoperative and last follow-up visits. Functional outcome was eventually evaluated by Odom's criteria. Surgery could significantly improve pain and disability from preoperative 6.2 ± 1.4 and 22.2 ± 6.2 to 3.5 ± 2.0 and 8.7 ± 5.2 (1-21) at the last follow-up visit, respectively. Satisfactory outcomes were observed in 89.7%. Symptom duration of more and less than six months had no effect on surgical outcome, but the results showed a statistically significant difference in NDI improvement in favor of the patients aged more than 45 years (P = 0.032), although pain improvement was similar in the two groups.

Since appropriate and time-table methods in trauma care have an important impact on patients'outcome, we evaluated the effect of Advanced Trauma Life Support (ATLS) program on medical interns' performance in simulated trauma patient management. A descriptive and analytical study before and after the training was conducted on 24 randomly selected undergraduate medical interns from Imam Reza Hospital in Mashhad, Iran. On the first day, we assessed interns' clinical knowledge and their practical skill performance in confronting simulated trauma patients. After 2 days of ATLS training, we performed the same study and evaluated their score again on the fourth day. The two findings, pre- and post- ATLS periods, were compared through SPSS version 15.0 software. P values less than 0.05 were considered statistically significant. Our findings showed that interns'ability in all the three tasks improved after the training course. On the fourth day after training, there was a statistically significant increase in interns' clinical knowledge of ATLS procedures, the sequence of procedures and skill performance in trauma situations (P less than 0.001, P equal to 0.016 and P equal to 0.01 respectively). ATLS course has an important role in increasing clinical knowledge and practical skill performance of trauma care in medical interns.

Determining the true prevalence of celiac disease (CD) is difficult because of many atypical symptoms. Although CD primarily affects the gastrointestinal tract, patients may be asymptomatic or have extra intestinal symptoms. In this study, we assessed the prevalence of CD in patients with epilepsy and the effect of a gluten-free diet on seizure control in these patients. Patients with epilepsy in Imam Reza and Farabi Hospitals, Kermanshah, Iran, were studied. At first, the patients were screened by means of measuring the immunoglobulin A antiendomysial (IgA) antibodies. In the patients testing positive for IgA antibodies, 2-3 endoscopic small bowel biopsies were taken from the distal duodenum to confirm CD changes. People with CD received a gluten-free diet for 5 months and their seizure activity was recorded. During the study period, we studied 113 patients with epilepsy. Seven patients (6%) were diagnosed with CD. After 5 months of instituting a gluten-free diet, in 6 patients seizures were completely under control and antiepileptic drugs were discontinued. In one case, anticonvulsant drugs were reduced by half and seizures were controlled. Our results showed that about 6% of epileptic patients were positive for CD. Institution of a glutenfree diet is useful for seizure control in these patients.

Toxocariasis is the clinical terms applied to infection of human with Ascarid nematodes in the order Ascaridida, named Toxocara canis and T. cati . Because in recent years in Iran many people desire to keep pets (cats and dogs), and lacking of seroepidemiological study of toxocariasis in Mashhad, we decided to determine the seroprevalence of toxocariasis among people who own cats and dogs in comparison with control group. A serological study for detection antibodies to Toxocara in two groups (93 cat and dog owners and 93 healthy people as control group) was conducted from Feb 2013 to Dec 2013. An ELISA method was employed using determination of IgG antibodies against Toxocara . The serum samples were evaluated for anti- Toxocara antibody, using ELISA technique at Parasitology and Immunology Lab of Imam Reza Hospital of Mashhad. Using a questionnaire, epidemiological factors associated with infection were examined. Data were analyzed using Chi-square test. The seroprevalence of Toxocara antibodies in the pet owners and control group was respectively 20.43% and 1.07%. 47.3% of pet owners were female. Presented data showed the significant difference between seroprevalence of toxocariasis among pet owners and control group. Education of society and in particular pet owners consisting of preventing contamination of the environment with Toxocara eggs is advised.

Introduction: Nurses’ spiritual wellbeing and their attitude toward spirituality and competence of nurses in providing of spiritual care can affect the quality of care in nursing. The aim of this study was to evaluate spiritual wellbeing, attitude toward spiritual care and its relationship with the spiritual care competence among nurses. Methods: This was a correlational descriptive study conducted on 109 nurses working in the Intensive Care Units of Imam Reza and Madani hospitals in 2015, Tabriz, Iran. Data collection tools were a demographic data form and three standard questionnaires including Spiritual Wellbeing Scale, Spirituality and Spiritual Results: The mean score of the spiritual wellbeing was 94.45 (14.84), the spiritual care perspective was 58.77 (8.67), and the spiritual care competence was 98.51 (15.44). The linear regression model showed 0.42 variance between the spiritual care competence scores which were explained by the two aspects of spiritual wellbeing (religious health, existential health) and three aspects of spiritual care perspective (spirituality, spiritual care, personalized care). The spiritual care competence had a positive relationship with spiritual wellbeing and spiritual care perspective. Conclusion: Because of the nature of nursing and importance of close interaction of nurses with patients in ICUs, the higher nurses’ SW and the more their positive attitude toward spiritual care, the more they can provide spiritual care to their patients.

The Inflammatory Bowel Disease (IBD) is considered as one of the chronic diseasesre-quiring complicated treatment. This study aimed to assess technical quality of providing care for pa-tients with IBD. This cross-sectional study was conducted on 94 people with IBD using interviews and simple random sampling methods in Gastroenterology, Endoscopy and clinic of Imam Reza Hospital and Golgasht Clinic in Tabriz in 2012. The data collection tool was a researcher-designed questionnaire whose validity and reliability had been confirmed. In order to investigate the statistical relationship between the background variables and compliance with the standards the Chi-square test was applied using SPSS 17 Software. "visit by the physician" and "diet advice by the dietitian" have had the highest and the lowest levels of compliance with the standard respectively, and "the care related to the disease exacerbation" and "the care provided by the other physicians" were not compatible with the standards in 80% of the cases. Data analyses also showed that there was a significant relationship between participant's age, job, education and the smoking status and compliance of some care with the relevant standards (P<0.05). The results indicate a substantial gap between provided care for the people with IBD and the relevant standards. This indicates the areas that need of improvement and requires the serious attention of the authorities.

Datura Stramonium (DS) is a common weed along roadsides, in cornfields and pastures and in waste areas. It belongs to the family Solanaceae and its toxic components are tropane belladonna alkaloids. It has been used voluntarily by teenagers for its hallucinogenic effect. The plant is named in Iran as Tatoore. Symptoms and signs of acute D. Stramonium poisoning usually are similar to anticholinergic syndrome. This study is done in order to clarify the status of this poisoning in our region. This study is a case series on all patients admitted to Imam Reza Hospital, Mashhad, Iran, with acute D. Stramonium poisoning between 2008 and 2011. We observed their symptoms, signs, routine laboratory test results and treatment used to control their symptoms. There were 19 patients included in our study. Children were poisoned more commonly than teenagers and poisoning in adults was rare. All of the children ingested the plant accidentally. The most presenting symptom was irritability and the most common sign was sinus tachycardia. There was not any presentation of seizure or coma. Most of the symptoms were controlled by parenteral benzodiazepines and there were no need to use of cholinergic agents such as physostigmine. Our study showed most of D. Stramonium poisoned population in our region are children. We suggest decreasing accessibility to the plant in order to decrease the incidence of its poisoning.

Gestational diabetes is one of the most common health problems in pregnancy that requires participation through self-care to reduce the maternal and neonatal complications. The present study aimed to determine the needs of women as an essential first step to formulate a self-care guide fitting the Iranian culture. The present qualitative study was conducted through interviews with 13 diabetic pregnant women and 10 care providers using semi-structured questionnaires in several cities of Iran in 2016. Further, the data analysis was performed using conventional content analysis. In addition, purposive sampling was performed at the diabetes clinic of Kermanshah University of Medical Sciences, Imam Reza Hospital, and health centers across Kermanshah, Shahroud, and Tehran. In the present qualitative content analysis study, four themes were identified: awareness and ability (knowing diabetes, mothers training and empowerment, continuity and quality, information resources), lifestyle (healthy diet, physical activity), mental health (counseling, interaction, spirituality, and religion), and supportive family (the husband's unique role, the psychological atmosphere at home). The present study highlighted main aspects of self-care educational/supportive needs, specifically in the domains of lifestyle, awareness and capability, mental health, and family. The results of our analysis highlighted the needs that can be useful for developing comprehensive self-care educational programs, with a higher focus on physical activity, mental health, the role of the family, and the use of religious interests.

This is the first comprehensive cohort study of the health of older people ever conducted in Iran. The aim of this project is to investigate the health status of older people in Amirkola in the northern part of Iran, near the Caspian Sea. The Amirkola Health and Ageing Project (AHAP) is mainly concerned with geriatric medical problems, such as falling, bone fragility and fractures, cognitive impairment and dementia, poor mobility and functional dependence. It is planned that all participants will be re-examined after 2 years. Data are collected via questionnaire, examinations and venepuncture. AHAP started in April 2011 and 1616 participants had been seen by 18 July 2012, the end of the baseline stage of this study. The participation rate was 72.3%. The prevalence of self-reported hypertension (41.2%) and diabetes mellitus (23.3%) are high. Only 14.4% of older people considered their health as excellent or good in comparison with others at this age. The prevalence of osteoporosis (T score≤-2.5) was 57.4% in women and 16.1% in men, and 38.2 % of older people were vitamin D deficient (<20 ng/ml).

Anxiety and spiritual distress are the most common problems among the patients admitted in intensive care units. The elderly are more vulnerable to this problem due to impairment of their adaptation mechanisms. Hence, helping to reduce anxiety is one of the most effective nursing interventions. Therefore, this study aimed at investigating the effect of need-based spiritual/religious interventions on spiritual well-being (SWB) and anxiety of the elderly admitted to coronary care unit (CCU). This quasi-experimental study with pre- and posttest control group design was conducted on 66 patients admitted to CCU of Imam Reza hospital in Lar, southern Iran, in 2014. After obtaining informed consents, the data were collected using the Spielberger State-Trait Anxiety Inventory, the SWB Scale, and a demographic questionnaire. The questionnaires were completed through interviewing the patients before and after the intervention. The participants of the intervention group underwent 60- to 90-minute sessions of spiritual and religious need-based interventions for 3 consecutive days. The results showed a significant increase in the mean scores of SWB in the intervention group after the intervention (P = .001). Also, a significant decrease was found in mean scores of trait and state anxiety in the intervention group in comparing to control group (P < .001). Moreover, a significant correlation was observed between the mean scores of SWB and state and trait anxiety. Spiritual/religious interventions could enhance SWB and reduce anxiety in the elderly admitted to CCU.

Abstract Summary Submission to the MetaboLights repository for metabolomics data currently places the burden of reporting instrument and acquisition parameters in ISA-Tab format on users, who have to do it manually, a process that is time consuming and prone to user input error. Since the large majority of these parameters are embedded in instrument raw data files, an opportunity exists to capture this metadata more accurately. Here we report a set of Python packages that can automatically generate ISA-Tab metadata file stubs from raw XML metabolomics data files. The parsing packages are separated into mzML2ISA (encompassing mzML and imzML formats) and nmrML2ISA (nmrML format only). Overall, the use of mzML2ISA & nmrML2ISA reduces the time needed to capture metadata substantially (capturing 90% of metadata on assay and sample levels), is much less prone to user input errors, improves compliance with minimum information reporting guidelines and facilitates more finely grained data exploration and querying of datasets.

CO poisoning is still a public health concern especially in developing countries. We aimed to focus on CO poisoning secular trends based on registry data for the recent 7 years in Northeast of Iran. Registry database of Imam Reza Hospital in Mashhad, Iran was analyzed. All admitted cases with CO exposure during 2004-2011 were included. Data from two national censuses were used for calculating rates. Data analyses was performed by SPSS 11.5. P < 0.05 was considered statistically significant. There were 443 CO related admissions (0.9% of all poisonings which equals to a prevalence rate of 1.9 per 100,000) during the 7-year period. Mean age was 32.3 ± 18.2 years and 60% of subjects were male. CO prevalence rate was not changed during this period. Case fatality rate was higher in men (5.4% vs. 4.4%). Self-employment and manual or office workers were at greatest risk. Age specific prevalence and mortality rates were highest in >60 age group. (2.9 and 3.1 per 100,000, respectively). As it seems that current health prevention studies are not effectively working, these secular trends can enlighten health policy makers to implement proper population based interventions like education or regulations for CO detectors. We believe that almost all cases of accidental CO poisoning can be prevented. Copyright © 2016 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Postoperative nausea and vomiting (PONV) is a common complication after general anesthesia, and the prevalence ranges between 25% and 30%. The aim of this study was to determine the preventive effects of dry cupping on PONV by stimulating point P6 in the wrist. This was a randomized controlled trial conducted at the Imam Reza Hospital in Kermanshah, Iran. The final study sample included 206 patients (107 experimental and 99 controls). Inclusion criteria included the following: female sex; age>18 years; ASA Class I-II; type of surgery: laparoscopic cholecystectomy; type of anesthesia: general anesthesia. Exclusion criteria included: change in the type of surgery, that is, from laparoscopic cholecystectomy to laparotomy, and ASA-classification III or more. Interventions are as follows: pre surgery, before the induction of anesthesia, the experimental group received dry cupping on point P6 of the dominant hand's wrist with activation of intermittent negative pressure. The sham group received cupping without activation of negative pressure at the same point. Main outcome was that the visual analogue scale was used to measure the severity of PONV. The experimental group who received dry cupping had significantly lower levels of PONV severity after surgery (P < 0.001) than the control group. The differences in measure were maintained after controlling for age and ASA in regression models (P < 0.01). Traditional dry cupping delivered in an operation room setting prevented PONV in laparoscopic cholecystectomy patients.

To develop and psychometrically assess spiritual health scale based on Islamic view in Iran. The cross-sectional study was conducted at Imam Ali and Quem hospitals in Mashhad and Imam Ali and Imam Reza hospitals in Bojnurd, Iran, from 2015 to 2016 In the first stage, an 81-item Likert-type scale was developed using a qualitative approach. The second stage comprised quantitative component. The scale's impact factor, content validity ratio, content validity index, face validity and exploratory factor analysis were calculated. Test-retest and internal consistency was used to examine the reliability of the instrument. Data analysis was done using SPSS 11. Of 81 items in the scale, those with impact factor above 1.5, content validity ratio above 0.62, and content validity index above 0.79 were considered valid and the rest were discarded, resulting in a 61-item scale. Exploratory factor analysis reduced the list of items to 30, which were divided into seven groups with a minimum eigen value of 1 for each factor. But according to scatter plot, attributes of the concept of spiritual health included love to creator, duty-based life, religious rationality, psychological balance, and attention to afterlife. Internal reliability of the scale was calculated by alpha Cronbach coefficient as 0.91. There was solid evidence of the strength factor structure and reliability of the Islamic Spiritual Health Scale which provides a unique way for spiritual health assessment of Muslims.

Thiopental sodium and Propofol are two widely-used drugs in the induction of anesthesia in assisted reproductive technology (ART). However, the side effects and outcome of recovery from anesthesia of these drugs on ART have not been identified yet. This study aimed at investigating the side effects and hemodynamic effects of using thiopental sodium and propofal as well as effects of these drugs on pregnancy outcome in ART cycles. In this double blinded) randomized controlled trial, 90 woman candidate for ART were randomly divided into two groups. 47 patients received Propofol (2.5 mg/kg) and 43 patients received thiopental (5mg/kg) for anesthesia induction. The entry hemodynamic parameters of the patients were documented. During the anesthesia process, hemodynamic parameters were checked at five-minute intervals. The results of the study showed a statistically significant difference between two groups in terms of their response to verbal stimulation (p<0.001), the normalization time of the rate and quality of breathing (p<0.001), nausea (p<0.001), and vomiting (p<0.001). Also, in comparison with the other group, all these parameters were better in Propofol group. There was found no significant difference between two groups in terms of other variables. Based on the findings of the study, Propofol has fewer known side effects. Vomiting and nausea as two known side effect of anesthesia are significantly lower in patients receiving Propofol than patients who received thiopental.

Background: Nowadays, ICU nurses play a significant role in the care of brain-dead patients and their families. Therefore, their knowledge, attitude and practice towards this issue are extremely important to the success of organ donation. Objective: To assess ICU nurses’ knowledge, attitude and practice towards their role in the organ donation process from brain-dead patients and factors influencing it in Iran. Methods: In a cross-sectional analytical study, 90 ICU nurses working in Ghaem and Emam Reza Hospitals affiliated to Mashhad University of Medical Sciences were selected through a stratified random sampling. Data were collected from the participants by a questionnaire included demographic information, and factors influencing the nurses knowledge, attitude, and practice towards their roles in the organ donation process. Results: 90 nurses participated in this study. 70% of the research subjects had spoken with their own families about organ donation; 20% had organ donation cards. The mean±SD score of nurses’ knowledge was 49.13±9.6, attitude 21.49±14.32, and practice was 3.66±6.04. 80% of nurses had a mean knowledge about their roles in the organ donation process; 82% agreed with their roles in this process, and 97% showed weak practice in this regard. Conclusion: Nurses did not have adequate knowledge, attitude, and practice towards their role in organ donation process. It is suggested to include nursing courses on the organ donation process and organ transplantation as well as educational programs to acquaint nurses with their roles in the organ donation process.

Omrani, Hasan, Mohammad Reza Alipour, Fereshteh Farajdokht, Hadi Ebrahimi, Mehran Mesgari Abbasi, and Gisou Mohaddes. Effects of chronic ghrelin treatment on hypoxia-induced brain oxidative stress and inflammation in a rat normobaric chronic hypoxia model. High Alt Med Biol. 18:145-151, 2017. This study aimed to evaluate the probable antioxidant effects of ghrelin in the brain and serum and its effect on tumor necrosis factor-alpha (TNF-α) levels in the brain in a model of chronic systemic hypoxia in rats. Systemic hypoxia was induced by a normobaric hypoxic chamber (O 2 11%) for ten days. Adult male Wistar rats were divided into control (C), chronic ghrelin (80 μg/kg/10 days) (Ghr), chronic hypoxia (CH), and CH and ghrelin (80 μg/kg/ip/10 days) (CH + Gh) groups. The activity of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), and malondialdehyde (MDA), total antioxidant capacity, and TNF-α levels were assessed in the serum and brain tissue. Our results showed that chronic ghrelin administration attenuated the CH-increased oxidative stress by decreasing MDA levels in the serum and brain tissue. Moreover, ghrelin enhanced the antioxidant defense against hypoxia-induced oxidative stress in the serum and brain tissue. Brain TNF-α levels in CH did not change significantly; however, ghrelin significantly (p < 0.001) decreased it. These results indicated that ghrelin promoted antioxidative and anti-inflammatory defense under chronic exposure to hypoxia. Therefore, ghrelin might be used as a potential therapy in normobaric hypoxia and oxidative stress induced by CH.

Evidence is mounting that magnet therapy could alleviate the symptoms of multiple sclerosis (MS). This study was performed to test the effects of the pulsing magnetic fields on the paresthesia in MS patients. This study has been conducted as a randomized, double-blind, parallel-group clinical trial during the April 2012 to October 2013. The subjects were selected among patients referred to MS clinic of Imam Reza Hospital; affiliated to Kermanshah University of Medical Sciences, Iran. Sixty three patients with MS were included in the study and randomly were divided into two groups, 35 patients were exposed to a magnetic pulsing field of 4mT intensity and 15-Hz frequency sinusoidal wave for 20min per session 2 times per week over a period of 2 months involving 16 sessions and 28 patients was exposed to a magnetically inactive field (placebo) for 20min per session 2 times per week over a period of 2 months involving 16 sessions. The severity of paresthesia was measured by the numerical rating scale (NRS) at 30, 60days. The study primary end point was NRS change between baseline and 60days. The secondary outcome was NRS change between baseline and 30days. Patients exposing to magnetic field showed significant paresthesia improvement compared with the group of patients exposing to placebo. According to our results pulsed magnetic therapy could alleviate paresthesia in MS patients .But trials with more patients and longer duration are mandatory to describe long-term effects.

Compelling evidence has shown that motor vehicle accidents have an enormous impact on mental health. Post-traumatic Stress Disorder (PTSD) is one of the most common psychological consequences in adult survivors of accidents, so it is important to understand the prevalence and predictors of this issue since delay causes damage to crucial daily functioning. This study aimed at investigating the prevalence and predictors of PTSD after motor vehicle accident. This cross-sectional study was conducted on 528 injured patients six weeks to six months after motor vehicle accident in Imam Reza Clinic of Poursina hospital, Rasht in 2015. Data collection tools were three questionnaires including post-traumatic stress-self report (PSS), Beck Depression Inventory (BDI-II), and the Numeric Rating Scale (NRS) for pain. The data were analyzed in SPSS (Version 19) using Chi-square, Fischer's exact test and multivariate logistic regression. Significance level was considered P≤0.05. The prevalence of PTSD and depression was 30.49% and 19.89% in participants, respectively. Chi-square test indicated a significant relationship among age (P=0.02), sex (P<0.001), education level (P<0.001), work status (P<0.001) and PTSD. Participants who reported pain (P<0.001) and depression (P<0.001) were more likely to have high score of PTSD than the others. Multivariate logistic regression showed this significance in sex, depression, age, educational status and pain, as constant risk factors in developing PTSD after accident. This study suggests that primary care setting should be readily prompted for diagnosis of these disorders in non-treatment seeking individuals in the community.

Morbid obesity is a chronic disease that contributes to increased oxidative stress. Gastric bypass surgery is the gold standard method in treating co-morbidities. The objective of this study was to evaluate the relation between pro-oxidant antioxidant balance (PAB) as one measure of oxidative stress and glycolipid profile 6 months after gastric bypass surgery. Imam Reza Hospital, Mashhad University of Medical Sciences, Mashhad, Iran. Thirty-five morbidly obese patients with body mass index ≥35 kg/m 2 with co-morbidities or ≤40 kg/m 2 were randomly recruited. The PAB assay was used to estimate oxidative stress. Anthropometrics and glycolipid profile were collected at recruitment and 6 months after surgery. Statistical analysis was performed using SPSS 16 software. The study showed a significant postoperative reduction in serum PAB values compared with the baseline (P<.001). All anthropometric and several glycolipid parameters significantly reduced after surgery (P<.001), while serum high-density lipoprotein cholesterol was unaffected. Repeated measures analysis of variance showed that postoperative PAB values were affected by gastric bypass surgery (F = 12.51, P = .001). Regression analysis demonstrated medication usage controlling co-morbidities (β^ = -.6, P = .002) and fasting blood glucose (β^ = .41, P = .04) as independent factors in predicting PAB values 6 months after surgery. Gastric bypass surgery can reduce PAB values in favor of antioxidants 6 months after the operation. Accordingly, fasting blood glucose after gastric bypass surgery can be an independent factor in predicting PAB values. Copyright © 2018 American Society for Bariatric Surgery.

Gastric cancer is one of the most prevalent cancers in the world. Characterized by poor prognosis, it is a frequent cause of cancer in Iran. The aim of the study was to design a predictive model of survival time for patients suffering from gastric cancer. This was a historical cohort conducted between 2011 and 2016. Study population were 277 patients suffering from gastric cancer. Data were gathered from the Iranian Cancer Registry and the laboratory of Emam Reza Hospital in Mashhad, Iran. Patients or their relatives underwent interviews where it was needed. Missing values were imputed by data mining techniques. Fifteen factors were analyzed. Survival was addressed as a dependent variable. Then, the predictive model was designed by combining both genetic algorithm and logistic regression. Matlab 2014 software was used to combine them. Of the 277 patients, only survival of 80 patients was available whose data were used for designing the predictive model. Mean ?SD of missing values for each patient was 4.43?.41 combined predictive model achieved 72.57% accuracy. Sex, birth year, age at diagnosis time, age at diagnosis time of patients' family, family history of gastric cancer, and family history of other gastrointestinal cancers were six parameters associated with patient survival. The study revealed that imputing missing values by data mining techniques have a good accuracy. And it also revealed six parameters extracted by genetic algorithm effect on the survival of patients with gastric cancer. Our combined predictive model, with a good accuracy, is appropriate to forecast the survival of patients suffering from Gastric cancer. So, we suggest policy makers and specialists to apply it for prediction of patients' survival.

Gender difference has been reported in stroke risk factors and disease history. The aim of this study was to compare risk factors and the severity of ischemic stroke based upon modified Rankin Scale (mRS) and hospital mortality between two genders. In a cross-sectional study, 341 patients (44% males and 56% females with a mean age of 68.94 ± 12.74 years) with ischemic stroke, who were hospitalized in the neurology wards of two referral university hospital of North-West Iran (Imam Reza and Razi Hospitals), from the beginning to the end of 2011 were selected and assessed. Gender difference in terms of demographic findings, vascular risk factors, 7(th) day mRS, and hospital mortality (during admission) were evaluated. In 2.6% of cases, mRS was found to be less than 2 (favorable) and in 97.4% of cases; mRS was 2-5 (with disability). No significant difference in ischemic stroke severity based on mRS was observed between two genders. There was a significant difference in the rate of hypertension (females = 72.3%, males = 59.3%, P = 0.010), diabetes (females = 28.8%, males = 18.7%, P = 0.030), smoking (females = 6.3%, males = 35.3%, P < 0.001). No significant difference was seen in other risk factors between two genders. There was no significant difference in the mortality rate, which constituted 8.9% and 4.7% in females and males respectively (P = 0.140). The evidence from the present study suggests that despite the existence of some difference between risk-factors in two genders, there was no difference in terms of ischemic stroke severity and mortality rate between two genders.

Dialysis patients need to deal and cope with various aspects of their disease. Identifying the adaptation methods provides valuable information for planning specific treatment and medical care delivery and improving the performance of medical teams. The present study aims to evaluate the coping strategies to stress among patients undergoing hemodialysis (HD) and peritoneal dialysis (PD) at the Imam Reza Educational-Medical Hospital, Tabriz, West Azarbaijan, Iran. This descriptive and analytical study was conducted on 70 patients in the year 2012. The subjects were selected through census method and simple random sampling method. Data were collected using a customized questionnaire and consisted of demographic information and the Jalowiec Coping Scale (JCS) through a structured interview. Descriptive and inferential statistics were used to analyze the data in SPSS (version 13). The mean score of frequency of use of the coping strategy as "sometimes used" for the HD patients was 70.94 ± 18.91 and also for PD patients as "seldom used" was 58.70 ± 12.66. The mean score of helpfulness of coping strategies in the HD group was 49.57 ± 19.42 as "slightly helpful", whereas in the PD group it was 37.21 ± 14.38 as "slightly helpful" Furthermore, both groups used the emotion-oriented coping styles more frequently than the problem-oriented methods. HD patients used coping methods more frequently than the PD patients. The majority of patients used emotion-oriented coping strategies to deal with stress factors. Use of educational, counseling and supportive programs to assist in coping techniques can facilitate the coping process with stress factors in dialysis patients.

Cardiac surgery under Cardiopulmonary bypass causes a systemic inflammatory response with a multifactorial etiology including direct tissue damage, ischemia and stimulation of immune system induced by cardiopulmonary bypass. This study was designed due to the high prevalence and complications of this stimulated immune system in mortality, morbidity, length of ICU stay, and mechanical ventilation. This study was aimed to compare preoperative and intraoperative methylprednisolone (MP) to intraoperative MP alone with respect to postbypass inflammation and clinical outcome. Sixty pediatric patients (age < 5years) undergoing cardiopulmonary bypass surgery between September 2011-2012 at Imam Reza hospital-Mashhad were randomly assigned to receive preoperative and intraoperative MP (group 1: 30 mg/kg, 4 hours before bypass and in bypass prime, n = 30) or intraoperative MP only (group 2: 30 mg/kg, n = 30). Postoperative temperature (peak temperature and average temperature during the first 24 hours), amount of inotropic, duration of mechanical ventilation, ICU stay, WBC, BUN, creatinine, and CRP were recorded and compared in both groups. Data were analyzed with SPSS version 13 by T-test, Mann-Whitney test if necessary, and Chi-squared distribution. Patient characteristics including age, weight, gender, and duration of bypass were almost similar in both groups (P > 0.05). No significant difference in amount of inotropic medications used for hemodynamic supports, duration of mechanical ventilation, peak and average temperature and length of ICU stay was observed. Among the laboratory tests (WBC, BUN, creatinine, CRP) only WBC counts raised more in group 2 when compared to group 1(P < 0.05). There was no difference in clinical outcome after cardiac surgery when we administered an additional dose of methylprednisolone compared to a single dose of methylprednisolone.

Posterior tibial slope (PTS) is an important factor in the knee joint biomechanics and one of the bone features, which affects knee joint stability. Posterior tibial slope has impact on flexion gap, knee joint stability and posterior femoral rollback that are related to wide range of knee motion. During high tibial osteotomy and total knee arthroplasty (TKA) surgery, proper retaining the mechanical and anatomical axis is important. The aim of this study was to evaluate the value of posterior tibial slope in medial and lateral compartments of tibial plateau and to assess the relationship among the slope with age, gender and other variables of tibial plateau surface. This descriptive study was conducted on 132 healthy knees (80 males and 52 females) with a mean age of 38.26±11.45 (20-60 years) at Imam Reza hospital in Mashhad, Iran. All patients, selected and enrolled for MRI in this study, were admitted for knee pain with uncertain clinical history. According to initial physical knee examinations the study subjects were reported healthy. The mean posterior tibial slope was 7.78± 2.48 degrees in the medial compartment and 6.85± 2.24 degrees in lateral compartment. No significant correlation was found between age and gender with posterior tibial slope ( P ≥0.05), but there was significant relationship among PTS with mediolateral width, plateau area and medial plateau. Comparison of different studies revealed that the PTS value in our study is different from other communities, which can be associated with genetic and racial factors. The results of our study are useful to PTS reconstruction in surgeries.

Spontaneous bacterial peritonitis (SBP) is a common and important clinical problem and is life-threatening in decompensated liver disease. Ascites fluid test by leukocyte esterase test strip has been recently proposed as an effective and rapid method to diagnose SBP in patients with cirrhosis. This study aimed to evaluate sensitivity and specificity of leukocyte esterase test strip in the diagnosis of SBP. The population of this research was all patients with cirrhosis and ascites admitted to the emergency room at Imam Reza (AS) hospital, Mashhad. A written consent was taken for inclusion in the study. 50 mL ascites sample was taken from all patients for use in a urine test strip (LER) (Urine Test Strips Convergys®Urine Matrix 11). The patient's ascites samples were evaluated for cell counting. Positive dipstick test for LER in this study considered as grade 3 +. The values of WBC > 500 cell/mm(3) or PMN > 250 cell/mm(3) considered as positive result of the gold standard method for the diagnosis of SBP. In this study, 100 patients with ascites due to cirrhosis, with an average age of 38.9 ± 6.54 years were evaluated. Twenty cases had positive results, of whom 17 cases were also detected based on the standard diagnostic criteria and other three cases were healthy individuals. Thus, sensitivity, specificity, positive and negative predictive values, and accuracy of the method were 95%, 96.3%, 85%, 97.5% and 95%, respectively. The use of leukocyte esterase urine dipstick test can be a quick and easy method in early diagnosis of SBP to start the treatment until preparation of SBP-cell count results.

Introduction The European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) is a prediction model which maps 18 predictors to a 30-day post-operative risk of death concentrating on accurate stratification of candidate patients for cardiac surgery. Objective The objective of this study was to determine the performance of the EuroSCORE II risk-analysis predictions among patients who underwent heart surgeries in one area of Iran. Methods A retrospective cohort study was conducted to collect the required variables for all consecutive patients who underwent heart surgeries at Emam Reza hospital, Northeast Iran between 2014 and 2015. Univariate and multivariate analysis were performed to identify covariates which significantly contribute to higher EuroSCORE II in our population. External validation was performed by comparing the real and expected mortality using area under the receiver operating characteristic curve (AUC) for discrimination assessment. Also, Brier Score and Hosmer-Lemeshow goodness-of-fit test were used to show the overall performance and calibration level, respectively. Results Two thousand five hundred eight one (59.6% males) were included. The observed mortality rate was 3.3%, but EuroSCORE II had a prediction of 4.7%. Although the overall performance was acceptable (Brier score=0.047), the model showed poor discriminatory power by AUC=0.667 (sensitivity=61.90, and specificity=66.24) and calibration (Hosmer-Lemeshow test, P<0.01). Conclusion Our study showed that the EuroSCORE II discrimination power is less than optimal for outcome prediction and less accurate for resource allocation programs. It highlights the need for recalibration of this risk stratification tool aiming to improve post cardiac surgery outcome predictions in Iran. PMID:29617500

Please cite this paper as: bin‐Reza et al. (2012) The use of masks and respirators to prevent transmission of influenza: a systematic review of the scientific evidence. Influenza and Other Respiratory Viruses 6(4), 257–267. There are limited data on the use of masks and respirators to reduce transmission of influenza. A systematic review was undertaken to help inform pandemic influenza guidance in the United Kingdom. The initial review was performed in November 2009 and updated in June 2010 and January 2011. Inclusion criteria included randomised controlled trials and quasi‐experimental and observational studies of humans published in English with an outcome of laboratory‐confirmed or clinically‐diagnosed influenza and other viral respiratory infections. There were 17 eligible studies. Six of eight randomised controlled trials found no significant differences between control and intervention groups (masks with or without hand hygiene; N95/P2 respirators). One household trial found that mask wearing coupled with hand sanitiser use reduced secondary transmission of upper respiratory infection/influenza‐like illness/laboratory‐confirmed influenza compared with education; hand sanitiser alone resulted in no reduction. One hospital‐based trial found a lower rate of clinical respiratory illness associated with non‐fit‐tested N95 respirator use compared with medical masks. Eight of nine retrospective observational studies found that mask and/or respirator use was independently associated with a reduced risk of severe acute respiratory syndrome (SARS). Findings, however, may not be applicable to influenza and many studies were suboptimal. None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection. Some evidence suggests that mask use is best undertaken as part of a package of personal protection especially hand hygiene. The effectiveness of masks and respirators is likely linked to

Blood and its derivatives are one of the most lifesaving products in the modern medicine practice. However, it is not an absolutely safe prescription. Many adverse effects such as infection, transfusion-related acute lung injury, immunosuppression, multi-organ dysfunction, acute respiratory syndrome, transfusion errors, transmission of infectious agents such as HIV, HBV, HCV are attributable to blood transfusion. The aim of this study was to describe how and when blood products were transfused in a referral burn center. This cross-sectional study was performed on medical records of all admitted patients in the Department of Burns and Reconstructive Surgery of Imam Reza Hospital, Mashhad, Iran during September 2014 up to August 2015. Transfusion measures such as Hb, Hct and demographic data were extracted from patient records. SPSS version 11.5 was used for data analysis. During the study period, 701 acute burnt patients were admitted with the mean age of 25.5±20.5 years. Sixty-four percent were male and burnt percentage of total body surface area (TBSA) was 30.9±24.3%. About one third (240) of patients received at least one blood product. Mean of the transfused packed red blood cell was 274.1±674.6mL per patient and 8.85mL per 1% of burnt TBSA. Anemia was the most common transfusion trigger. Mortality in burnt patients who received blood products was two folds more than patients who did not receive any blood products. We prescribed less blood products compared with other reviewed burn centers. However, following a written blood transfusion protocol by all clinicians may reduce blood transfusion in unnecessary situations even more significantly. Copyright © 2017 Elsevier Masson SAS.

Appendicitis is the most common cause of severe abdominal pain in the world, and the associated postsurgical pain, as occurs with other surgical procedures, is one of the most common problems. Today, there is a growing tendency toward nondrug methods and alternative medicine to reduce the adverse effects of drugs. Reflexology involves applying pressure on certain areas of the palms, feet, and ears in order to reduce stress and pain in certain areas of the body. The aim of this study was to determine the effect of reflexology massage on pain relief after appendectomy. This clinical trial was conducted at the surgical emergency unit of Imam Reza Hospital of Mashhad, Iran, in 2013. Pain intensity and analgesic consumption were compared between 105 patients before and immediately, 1 hour, 6 hours, and 24 hours after the intervention in three groups of intervention, control, and placebo. Patients in all three groups received analgesics, as required. The experimental group received pressure on a defined area of the right foot for about 10 minutes and the Shen Men point of the ear for 1 minute. This pressure in the placebo group was applied on the left foot and the left earlobe. Patients in the control group received routine care only. The results were evaluated at a 95% confidence level, and data were analyzed using SPSS software version 12 (SPSS, Inc., Chicago, IL). At the beginning of the study, the mean pain intensity in different groups according to analysis of variance was not significantly different (p = 0.439); however, there was a notable difference in pain intensity between the intervention and other groups after reflexology therapy. In addition, methadone consumption was significantly lower in the reflexology group than in the other two groups (p ≤ 0.001). Reflexology is effective for reducing pain after appendectomy surgery.

Background: Gender difference has been reported in stroke risk factors and disease history. The aim of this study was to compare risk factors and the severity of ischemic stroke based upon modified Rankin Scale (mRS) and hospital mortality between two genders. Methods: In a cross-sectional study, 341 patients (44% males and 56% females with a mean age of 68.94 ± 12.74 years) with ischemic stroke, who were hospitalized in the neurology wards of two referral university hospital of North-West Iran (Imam Reza and Razi Hospitals), from the beginning to the end of 2011 were selected and assessed. Gender difference in terms of demographic findings, vascular risk factors, 7th day mRS, and hospital mortality (during admission) were evaluated. Results: In 2.6% of cases, mRS was found to be less than 2 (favorable) and in 97.4% of cases; mRS was 2-5 (with disability). No significant difference in ischemic stroke severity based on mRS was observed between two genders. There was a significant difference in the rate of hypertension (females = 72.3%, males = 59.3%, P = 0.010), diabetes (females = 28.8%, males = 18.7%, P = 0.030), smoking (females = 6.3%, males = 35.3%, P < 0.001). No significant difference was seen in other risk factors between two genders. There was no significant difference in the mortality rate, which constituted 8.9% and 4.7% in females and males respectively (P = 0.140). Conclusion: The evidence from the present study suggests that despite the existence of some difference between risk-factors in two genders, there was no difference in terms of ischemic stroke severity and mortality rate between two genders.

This study aimed to evaluate the therapeutic results and safety of pectoralis major muscle turnover flaps in the treatment of mediastinitis after coronary artery bypass grafting (CABG) procedures. Data regarding 33 patients with post-CABG deep sternal wound infections (DSWIs) who underwent pectoralis major muscle turnover flap procedures in the Emam Reza and Ghaem Hospitals of Mashhad, Iran were reviewed in this study. For each patient, age, sex, hospital stay duration, remission, recurrence, and associated morbidity and mortality were evaluated. Of the 2,447 CABG procedures that were carried out during the time period encompassed by our study, DSWIs occurred in 61 patients (2.5%). Of these 61 patients, 33 patients (nine females [27.3%] and 24 males [72.7%]) with an average age of 63±4.54 years underwent pectoralis major muscle turnover flap placement. Symptoms of infection mainly occurred within the first 10 days after surgery (mean, 10.24±13.62 days). The most common risk factor for DSWIs was obesity (n=16, 48.4%) followed by diabetes mellitus (n=13, 39.4%). Bilateral and unilateral pectoralis major muscle turnover flaps were performed in 20 patients (60.6%) and 13 patients (39.4%), respectively. Complete remission was achieved in 25 patients (75.7%), with no recurrence in the follow-up period. Four patients (12.1%) needed reoperation. The mean hospitalization time was 11.69±6.516 days. Four patients (12.1%) died during the course of the study: three due to the postoperative complication of respiratory failure and one due to pulmonary thromboembolism. Pectoralis major muscle turnover flaps are an optimal technique in the treatment of post-CABG mediastinitis. In addition to leading to favorable therapeutic results, this flap is associated with minimal morbidity and mortality, as well as a short hospitalization time.

de la Reza et al. (1997) suggested that all K giants become Li-rich for a short time. During this period the giants are associated with an expanding thin circumstellar shell supposedly triggered by an abrupt internal mixing mechanism resulting in the surface Li enrichment. In order to test this hypothesis twenty nine late-type giants with far-infrared excess from the list of Zuckerman et al. (1995) were observed in the Li-region to study the connection between the circumstellar shells and Li abundance. Eight giants have been found to have log epsilon (Li) > 1.0. In the remaining giants the Li abundance is found to be much lower. HD 219025 is found to be a rapidly rotating (projected rotational velocity of 23 +/-3 km s(-1) ), dusty and Li-rich (log epsilon (Li) = 3.0+/-0.2) K giant. Absolute magnitude derived from the Hipparcos parallax reveals that it is a giant and not a pre-main-sequence star. The evolutionary status of HD 219025 seems to be similar to that of HDE 233517 which is also a rapidly rotating, dusty and Li-rich K giant. The Hipparcos parallaxes of all the well studied Li-rich K giants show that most of them are brighter than the ``clump" giants. Their position in the H-R diagram indicates that they have gone through mixing and the initial abundance of Li is not preserved. There seems to be no correlations between Li abundances, rotational velocities and carbon isotope ratios. The only satisfactory explanation for the overabundance of lithium in these giants is the creation of Li by the extra deep mixing and the associated ``cool bottom processing".

Venography is an invasive diagnostic test that uses contrast material that provides a picture of the condition of the veins. But, complications, including adverse effects on the kidney, do occur. On the other hand, with the current technological development, application of ultrasound in the diagnosis of obstructive diseases of the veins is gaining popularity, being non-invasive, easy to perform and cost-effective. The aim of this study was to evaluate the diagnostic value of Doppler sonography in the diagnosis of central vein stenosis. In this descriptive-analytical study, 41 hemodialysis patients who had been referred for 50 upper limb venographies to the radiology department of Imam Reza (AS) were included. Patients with chronic kidney disease with a history of catheterization of the vein, jugular or subclavian, and who had established fistulas or synthetic vascular grafts were targeted. Central venous ultrasound was performed on both sides to evaluate stenosis or occlusion. Venography was performed by the radiologist the next day or the day before hemodialysis. Data on demographic characteristics, findings of clinical examination and findings of ultrasound as well as venography were recorded by using the SPSS software, Chi-square test and Spearman correlation, and Kappa agreement was calculated for sensitivity, specificity and predictive values. Twenty-three (56%) patients were male subjects and 18 patients (44%) were female. Twenty-three (56%) patients of the study population were aged <60 years and 18 (43/9%) patients were aged >60 years. The overall sensitivity, specificity and positive predictive value and negative predictive value of Doppler sonography in the proximal veins in hemodialysis patients compared with venography were, respectively, 80.9%, 79.3%, 73.9% and 85.1%. Color Doppler sonography, as a non-invasive method, could be a good alternative for venography in the assessment of the upper limb with central vein stenosis and occlusion.

To determine treatment efficacy of curettage on endometrial polyp. The quasi-experimental pre-and-post study was conducted in 2011-12 at the gynaecology department of Imam Reza Hospital, Mashhad, Iran, and comprised patients who underwent hysteroscopy for endometrial polyp. Location, size, number and base condition of the polyps were recorded before the patient underwent curettage. Hysteroscopy was then performed and the condition of the remaining polyps was compared with initial findings. Also, the remaining polyps were resected. SPSS 13 was used for statistical analysis. There were 51 patients in the study with a mean age of 33.14 ± 8.19 years (range: 23-59 years)Besides, there were 82 polyps; 38(46.3%) having a narrow base, and 44(53.7%) having a wide base. The mean polyp size was 2.39 ± 2.63cm.After performing curettage, 23 (28.0%) polyps were removed completely, 39(47.6%) had size reduction, and 20(24.4%) had no change in size. Curettage could not significantly remove polyps (p < 0.001). Polyps smaller than 2cm were more likely to have been removed compared to the bigger ones (p = 0.003).Polyps with wide base were more significantly removed than those with narrow base (p < 0.001).Further, those with wide base and also smaller than 2 cm were removed more significantly than others (p < 0.001).The location of polyps had no effect on removal probability by curettage (p = 0.114). Curettage was not found to be a reliable method for endometrial polyp removal. If hysteroscopy is not accessible, the size of the polyp should be determined by vaginal sonograghy to estimate the probability of its removal by curettage.

Background Cardiac surgery under Cardiopulmonary bypass causes a systemic inflammatory response with a multifactorial etiology including direct tissue damage, ischemia and stimulation of immune system induced by cardiopulmonary bypass. This study was designed due to the high prevalence and complications of this stimulated immune system in mortality, morbidity, length of ICU stay, and mechanical ventilation. Objectives This study was aimed to compare preoperative and intraoperative methylprednisolone (MP) to intraoperative MP alone with respect to postbypass inflammation and clinical outcome. Patients and Methods Sixty pediatric patients (age < 5years) undergoing cardiopulmonary bypass surgery between September 2011-2012 at Imam Reza hospital-Mashhad were randomly assigned to receive preoperative and intraoperative MP (group 1: 30 mg/kg, 4 hours before bypass and in bypass prime, n = 30) or intraoperative MP only (group 2: 30 mg/kg, n = 30). Postoperative temperature (peak temperature and average temperature during the first 24 hours), amount of inotropic, duration of mechanical ventilation, ICU stay, WBC, BUN, creatinine, and CRP were recorded and compared in both groups. Data were analyzed with SPSS version 13 by T-test, Mann-Whitney test if necessary, and Chi-squared distribution. Results Patient characteristics including age, weight, gender, and duration of bypass were almost similar in both groups (P > 0.05). No significant difference in amount of inotropic medications used for hemodynamic supports, duration of mechanical ventilation, peak and average temperature and length of ICU stay was observed. Among the laboratory tests (WBC, BUN, creatinine, CRP) only WBC counts raised more in group 2 when compared to group 1(P < 0.05). Conclusions There was no difference in clinical outcome after cardiac surgery when we administered an additional dose of methylprednisolone compared to a single dose of methylprednisolone.

BACKGROUND Constipation is one of the most frequent cause of patient visits to pediatric gastroenterology clinics. Early diagnosis and treatment is important. There are few studies about clinical manifestations of constipation in children. We aimed to find the relative frequency of gastrointestinal manifestations of constipation among constipated children. METHODS This cross-sectional study was carried out on children aged < 18 years old with chronic functional constipation referred to Imam Reza Clinic of Shiraz University of Medical Sciences. Children with organic causes of chronic constipation were excluded from study. Rome III criteria were used for defining constipation. The duration of study was 1 year starting from September 2010. Abdominal pain, fecal mass, rectal bleeding, anorexia, fecal soiling, retentive posture, withholding behavior, anal fissure, and peri-anal erythema were recorded for each case based on history and physical examination. Data were analyzed using SPSS software, version 13.0 (Chicago, IL, USA). RESULTS Of 222 children with functional constipation, 124(55.9%) were girls and 98 (44.1%) were boys with a mean ± SD age of 5±3.12 years. The mean ± SD duration of constipation was 2.2±1.9 years. Large and hard stool was present in 93.7% of the patients. Painful defecation and withholding behavior were seen in 92.3% and 91.9% of the patients, respectively. Fecal impaction was more frequent among boys compared with girls (p<0.01). Fecal soiling was present in 40.8% of the boys and 28.2% of the girls (p=0.04). CONCLUSION Large and hard stool, painful defecation and withholding behavior were the most frequent signs or symptoms among children with chronic functional constipation. Fresh rectal bleeding and anal fissure were the least frequent signs and symptoms in this group. PMID:25628851

Crystal Growth Using MEPHISTO

The shuttle flight experiment "In Situ Monitoring of Crystal Growth Using MEPHISTO" was accomplished during STS-87 as part of the fourth flight of the United States Microgravity Payload (USMP-4), which was flown from November 19 to December 5, 1997. The data returned from that flight are just now beginning to yield quantitative results. This project is an international collaboration: the furnace system known as MEPHISTO was built in France by CNES (French National Space Agency) and CEA (French Atomic Energy Commission); the principal investigator, Prof. Reza Abbaschian, is from the University of Florida at Gainesville; and numerical and analytical modeling support includes collaborators from the University of New South Wales, Australia, the University of Wisconsin at Milwaukee, the National Institute of Standards and Technology, and the NASA Lewis Research Center. MEPHISTO is a French acronym that translates into English as Materials for the Study of Interesting Phenomena of Solidification on Earth and in Orbit. Since this was the fourth flight of the MEPHISTO furnace, the experiment is referred to as MEPHISTO-4. MEPHISTO-4 was a directional solidification experiment that studied the liquid-to-solid transformation of bismuth alloyed with tin. Directional solidification is a freezing technique common to the processing of the electronic materials used in integrated circuits and detectors, such as silicon and germanium. When liquids are frozen on Earth, they must be cooled. The cooling causes stirring because of density variations in the liquid. This stirring, known as natural convection, influences the quality of the resulting solid. During freezing, regions of high and low concentrations of tin are created. This introduces another important phenomenon: diffusion, or the movement by molecular action of matter from regions of high concentration to regions of lower concentration. In MEPHISTO-4, it is tin that diffuses from the high-concentration region in front of the

Angular Momentum Evolution in Young Low Mass Stars

During the last decades, the study of rotation in young low mass stars has been one of the more active areas in the field of stellar evolution. Many theoretical efforts have been made to understand the angular momentum evolution and our picture now, reveals the main role of the stellar magnetic field in all pre-main sequence stage (Ghosh & Lamb 1979, ApJ, 234, 296; Cameron & Campbell 1993, A&A, 274, 309; Cameron & Campbell 1995, A&A, 298, 133; Kúker, Henning, & Rúdiger 2003, ApJ, 589, 397; Matt & Pudritz 2005, MNRAS, 356, 167). The mean rotation of most of the cool low mass stars remains roughly constant during the T Tauri stage. This can be explained by the disc locking scenario. This paradigm suggest that star start out as CTTS with periods of 4-14 days, perhaps locked to their disc, and that this disc is eventually lost mainly by accretion. At the current time, it is not clear that this is true for all low mass stars. Some authors have questioned its validity for stars less massive than 0.5 solar masses. Although the reality may eventually turn out to be considerably more complex, a simple consideration of the effects of and limits on disc locking of young low mass stars seems necessary.We have investigated the exchange of angular momentum between a low mass star and an accretion disc during the Hayashi Track (Pinzón, Kúker, & de la Reza 2005, in preparation) and also along the first 100Myr of stellar evolution. The model incorporates changes in the star's moment of inertia, magnetic field strength (Elstner & Rúdiger 2000, A&A, 358, 612), angular momentum loss by a magnetic wind and an exponential decrease of the accretion rate. The lifetime of the accretion disc is a free parameter in our model. The resulting rotation rates are in agreement with observed vsin and photometric periods for young stars belonging to co-moving groups and open young clusters.

Clinical experience associated with the fear and anxiety of nursing students in the psychiatric unit. Mental health nursing instructors find it challenging to teach nursing students to deal with patients with mental disorders in an environment where they need to provide patient teaching and clinical decision-making based on evidence and new technology. To measure the effectiveness of clinical teaching of mental health courses in nursing using clinical supervision and Kirkpatrick's model evaluation in the psychiatry unit of Imam Reza Hospital, Bojnurd, Iran. This cross-sectional study was carried out from 2011 to 2016 on 76 nursing students from a university as part of a clinical mental health course in two semesters. The students were selected by a non-probable convenient sampling method. After completing their clinical education, each student responded to checklist questions based on the four-level Kirkpatrick's model evaluation and open questions relating to clinical supervision. Finally, all data was analyzed using the SPSS version 16. The students have evaluated clinical supervision as a useful approach, and appreciated the instructor's supportive behavior during teaching and imparting clinical skills. This has made them feel relaxed at the end of the clinical teaching course. In addition, in the evaluation through Kirkpatrick's model, more than 70% of the students have been satisfied with the method of conducting the teaching and average score of nursing students' attitude toward mental health students: Their mean self-confidence score was 18.33±1.69, and the mean score of their performance in the study was evaluated to be 93.74±5.3 from 100 points. The results of clinical mental health teaching through clinical supervision and Kirkpatrick's model evaluation show that the satisfaction, self-esteem, attitude, and skill of nursing students are excellent, thereby portraying the effectiveness of clinical teaching. But this program still needs to be reformed. To

Background Distal radius fractures are among the most prevalent fractures predictive of probable occurrence of other osteoporotic fractures. They are treated via a variety of methods, but the best treatment has not been defined yet. Objectives This study was performed to compare the results of open reduction and internal fixation with locking plates versus the pin and plaster method. Materials and Methods In this prospective study, 114 patients aged 40 to 60 years with Fernandez type III fracture referring to Imam-Reza and Mehr hospitals of Mashhad from 2009 to 2011, were selected randomly; after obtaining informed consent, they were treated with pin and plaster fixation (n = 57) or internal fixation with the volar locking plate (n = 57). They were compared at the one year follow up. Demographic features and standard radiographic indices were recorded and MAYO, DASH and SF - 36 tests were performed. Data was analyzed by SPSS software version 13, with descriptive indices, Mann-Whitney and Chi-square tests. Results SF-36 test demonstrated a better general health (P < 0.001), mental health (P = 0.006), physical functioning (P < 0.001), social functioning (P < 0.001) and energy/fatigue (P < 0.001) in LCP group. However, pain (P = 0.647) was not significantly different between the groups. Physical limitation (P < 0.001) and emotional limitation (P < 0.001) were greater in the pin and plaster group. Also, in the LCP group mean MAYO score (P < 0.001) was more than pin and plaster group. Mean DASH score was not different between the groups (P = 0.218). The rate of acceptable results of radiographic indices (P < 0.001), grip strength (P < 0.001) and range of motion in supination-pronation (P < 0.001) in LCP method were better than the pin and plaster method. Conclusions In treatment of intra-articular distal radius fractures in middle-aged patients internal fixation with locking plates may be prefered to pin and plaster as the treatment of choice.

Background: Perforated appendicitis is one of the most common causes of acute abdomen requiring emergent surgery for immediate appendectomy and peritoneal cavity irrigation; however, the efficacy of irrigation with antibiotic solutions is controversial. Objectives: The aim of this study was to assess the efficacy of imipenem solution irrigation on post-operative surgical site infections (SSIs), hospital length of stay, and hospital costs. We hypothesized that there would be lower rate of SSIs, a shorter hospital stay, and lower hospital cost in patients with perforated appendicitis who received peritoneal cavity irrigation with imipenem solution in comparison to their counterparts who received irrigation with normal saline. Patients and Methods: In this randomized single-blind parallel-group clinical trial, we enrolled 90 patients with perforated appendicitis with 12-50 years of age and randomly allocated them into experimental group (n = 45) and control group (n = 45). The control group received peritoneal irrigation with normal saline (0.9%) and experimental group underwent peritoneal irrigation with imipenem solution (1 mg/mL). All surgical procedures were performed in Imam Reza Hospital of Kermanshah University of Medical Sciences. The study primary outcome was surgical site infections (including wound infection and abdominal abscess) and the secondary outcomes were length of hospital stay and hospital cost. Chi-squared and t-tests were used to analyze the study data. Results: Imipenem solution irrigation was associated with significant clinical improvement at one-month follow-up. The experimental group presented with significantly lower rate of SSIs and shorter length of hospital stay. The experimental group had lower rate of SSIs compared to the control group (4.4% vs. 22.2%, respectively) (p= 0.013). The duration of hospital stay was nearly one day longer in control group (5.84 ± 2.58 days) vs. experimental group (4.91 ± 1.29 days) (P = 0.034), and

It is believed that an exaggerated blood pressure response (EBPR) to exercise stress test is associated with a higher risk of cardiovascular events. It is also assumed that QT dispersion (QT-d), which was originally proposed to measure the spatial dispersion of ventricular recovery times, may have a relationship to cardiovascular events. The objective of this study was to examine the difference of changes in QT-d, Maxi-QT, Mini-QT, and QT-c (corrected QT interval) of the electrocardiogram in two groups of patients with exaggerated blood pressure responses (EBPR group) and normal responses (control group) to exercise testing. Also, the diagnostic value of each of these criteria in the prediction of EBPR was studied. This cross-sectional study was conducted from May 2015 to February 2016 on patients suspected of coronary artery disease (CAD) undergoing exercise testing who had been referred to Ghaem and Imam Reza hospitals in Mashhad (Iran). All patients underwent a treadmill exercise test with the 12-lead ECG, which was optically scanned and digitized for analysis of QT-d, QT max, and QT min. Patients were divided into two groups of normal and EBPR to exercise testing. QT changes of ECG were compared between the two groups, and the diagnostic accuracy of QT variables for prediction of EBPR to exercise testing was studied. A multiple linear regression analysis (MLR), Pearson Chi-qquare, independent samples t-test, and receiver operating characteristic (ROC) curve were used as statistical methods in IBM SPSS version 19. Sixty patients (55% male) with a mean age of 50.48 ± 10.89 years were studied in two groups of normal (n=30) and exaggerated blood pressure response (n=30) to exercise testing. Maximum QT and QT dispersion were statistically different in individuals' exaggerated blood pressure response to exercise stress test (p < 0.05). The logistic regression analysis revealed that none of our parameters predicted the EBPR. The ROC curve showed that 50 and 345

Dexmedetomidine is an intravenous alpha-2 agonist and very specific short-acting drug to protect the various organs against ischemic injuries and blood reflow. However, the effect of dexmedetomidine for preventing intraoperative heart arrhythmias has not been recognized. This study aimed to determine the effect of dexmedetomidine on the incidence rate of heart arrhythmias and anesthetic required in off-pump coronary artery bypass surgery. This randomized clinical trial was conducted on patients who were candidates for off-pump coronary artery bypass referring to Imam Reza Hospital of Mashhad, Iran, from July 2016 through January 2017. The patients were randomly assigned to two groups of intervention (infusion of 0.5 mcg/kg/h dexmedetomidine together with induction followed by infusion of 0.5 mcg/kg/h by the end of the surgery) or control (saline infusion). Mean arterial pressure (MAP) and heart rate (HR) were measured before induction, during surgery operation and ICU admission. Data were analyzed by SPSS version 18 using Chi Square and independent-samples t-test. A total of 76 patients with a mean age of 59.8 ± 8.2 years (in two groups of 38) were studied. The two groups had no statistically significant difference in terms of background variables. The MAP and HR values before induction, during surgery and ICU admission were significantly higher in the control group than in the intervention group (p=0.001). Out of the studied arrhythmias, the values of PAC (55.2% vs. 15.7%), PVC (81.5% vs. 21.0%), AF (26.3% vs. 7.8%), VTAC (21.0% vs. 2.6%) were significantly lower in dexmedetomidine group (p=0.001). It seems that dexmedetomidine administration during induction and surgery can cause significant reduction in most of the common arrhythmias in off-pump coronary bypass surgery. The use of dexmedetomidine maintains MAP and HR at significantly lower values, and changes

Background Nicorandil leads to the relaxation of fine vascular smooth muscle, and thus causes vasodilatation of major epicardial. Also, it has anti-arrhythmic and cardio-protective effects by improving reperfusion, and ultimately leads to a reduction in microvascular damage caused by percutaneous coronary intervention (PCI). Objective The aim of this study was to determine the effect of nicorandil on QT interval dispersion (QTd) in patients with stable angina pectoris during elective angioplasty. Methods This triple-blind and randomized clinical trial was performed on patients with stable angina pectoris, candidates for elective angiography referred to Imam Reza and Ghaem hospitals in Mashhad, Iran, between January and October 2016. The patients were randomly assigned to one of two groups receiving nicorandil (60 mg as 20 mg before and 40 mg after PCI) and placebo. All the patients underwent electrocardiography 12 hours before and 12 hours after PCI. The values of maximal corrected QT interval (QTc max) and QTd in these intervals, and the levels of changes in the QTd (QTd difference before angiography and after PCI) were compared between the two groups. Data were analyzed statistically using SPSS version 18 software via Chi-square and Independent-samples t-test. Results This study was performed on 90 patients (55 males and 35 females) with a mean age of 58.6±10.8 years, on two groups of 45 people. The two groups were matched for age, body mass index, cardiovascular risk factors and baseline testing. The QTd before angiography had no statistically significant difference between the patients of both groups (control: 77.7±17.1 vs. nicorandil: 80.7±14.2 ms; p=0.371). The QTd after PCI in the nicorandil group was lower than the control group (48.1±14.2 vs. 59.2±15.6 ms; p=0.000). The decrease rate in QTd had a statistically significant difference between the two groups (control: 18.9±11.0 vs. nicorandil: 33.5±9.5 ms; p=0.000). Conclusions The results of this

Rib fractures are the most common skeletal thoracic injuries resulting from blunt chest trauma. Half of the rib fractures are not detected upon a precise physical evaluation and radiographs. Recently ultrasonography (USG) has been investigated to detect rib fractures. But based on literature the usefulness of USG varies widely. This study was conducted to investigate the role of USG in the detection of possible rib fractures in comparison with radiography. In this cross-sectional study, consecutive patients with minor blunt chest trauma and suspected rib fractures presenting in Imam Reza Hospital located in Mashhad-Iran, between April 2013 and October 2013 were assessed by USG and radiography. The radiography was performed in a posteroanterior (PA) chest projection and oblique rib view centered over the area of trauma. The time duration spent in taking USG and radiography were recorded. The prevalence and location of fractures revealed by USG and radiography were compared. Sixty-one suspected patients were assessed. The male to female ratio was 2.4:1 (43 men and 18 women) with a mean ± SD age of (44.3 ± 19.7) years. There were totally 59 rib fractures in 38 (62.3%) patients based on radiography and USG, while 23 (37.7%) patients had no diagnostic evidence of rib lesions. USG revealed 58 rib fractures in 33 (54.1%) of 61 suspected patients and radiographs revealed 32 rib fractures in 20 (32.8%) of 61 patients. A total of 58 (98.3%) rib fractures were detected by USG, whereas oblique rib view and PA chest radiography showed 27 (45.8%) and 24 (40.7%) rib fractures, respectively. The average duration of USG was (12 ± 3) min (range 7-17 min), whereas the duration of radiography was (27 ± 6) min (range 15-37 min). The kappa coefficient showed a low level of agreement between both USG and PA chest radiography (kappa coefficient = 0.28), and between USG and oblique rib view (kappa coefficient = 0.32). USG discloses more fractures than radiography in

The emergence of magnetic Resonance Imaging (MRI) technique has made it possible to answer many questions in the field of anatomy more precisely while observing different anatomic parts of living persons at different ages. This study was conducted to determine the dimensions of different parts of pons and also comparing the data in accordance with age and sex by MRI. The present study carried out on 300 healthy individuals referred to imaging center at Imam Reza hospital in the city of Kermanshah, Iran. The precondition for people to be included in the study was the approval made by in-house physician based on person's state of health and the lack of any pathological lesion in brain on the basis of images obtained by MRI. Following MRI procedure, the dimensions of target parts in pons were calculated by the MRI-associated measuring system and recorded along with the age and sex of the patients. Measurements were recorded in mm and based on selecting the largest height, width and length of the organ during the examination of all axial, sagittal, and T(1) coronal profiles. Data analysis was performed using t-student test and Pearson's correlation. The significance level was set at P=0.05. The mean size of different parts of pons recorded in mm was as follows: The height of tegmentum of pons in men and women were 21.10+/-1.99 and 20.35+/-1.95, respectively. The height of ventricle of pons was 24.96+/-1.45 in men and 23.72+/-1.41 in women. The length of pons in men was 21.40+/-1.55 and in women 21.10+/-1.28. The length of ventricle in men and women were 16.85+/-1.21 and 16.77+/-1.36, respectively. The length of tegmentum of pons was 4.57+/-0.50 in men and 4.40+/-0.58 in women. Lastly, the transverse length of the ventricle of pons was 27.30+/-1.68 in men and 26.52+/-1.63 in women. The values obtained for the transverse length, length of tegmentum of ventricle, height of ventricle and height of tegmentum in men were larger than those found for women. There were

Background Chemotherapy induced nausea and vomiting (CINV) is a side effect, and has negative effect on quality of life and continuation of chemotherapy. Despite new regimen and drugs, the problems still remain and standard guidelines, effective treatment and supportive care for refractory CINV are still not yet established. Persian medicine, the old Iranian medical school, offer Persumac (prepared from Rhus Coriaria and Bunium Persicum Boiss). Objective The specific objectives were to assess the effect of Persumac on the number and severity of nausea and vomiting in refractory CINV in acute and delayed phase. Methods This randomized, double blind, crossover clinical trial study was carried out on 93 patients with breast cancer and refractory CINV, who received outpatient high emetogenic chemotherapy in Imam Reza hospital, Mashhad, Iran from October 2015 to May 2016. The study has three stages: in stage I patients received a questionaire and completed it after chemotherapy. In stage II they were randomly divided into intervention group with Persumac and control group with placebo (lactose were used). In stage III, wash out and crossover was conducted. Both groups in all stages received standard antiemetic therapy for CINV. The following were set as the inclusion criteria of the study: female, Age ≥18 years, clinical diagnosis of breast cancer, history of refractory CINV, normal blood tests and at least three courses of chemotherapy remaining. Exclusion criteria of this study were: Total or upper abdominal radiation therapy along with chemotherapy, drugs/therapy for nausea and vomiting not prescribed in this study, hypersensitivity to Sumac or Bunium Persicum, use of sumac and Bunium Persicum in seven days prior to the intervention, clinical diagnosis of digestion disorders, non-chemotherapy induced nausea and vomiting, milk allergy, loss of two consecutive or three intermittent doses of Persumac or placebo. Outcomes were gathered by Persian questionnaire. Number

I Kalfas and Reza S Abhari Laboratory for Energy Conversion, Department of Mechanical and Process Engineering, ETH Zurich, Zurich, Switzerland and Department of Mechanical Engineering, Aristotle University of Thessaloniki, Greece The paper [2] describes the development of a probe for measuring time-resolved entropy fluctuations. The technique was developed for use in turbomachinery applications where knowledge of the unsteady entropy in the wake of a rotating blade row can provide significant insight into the loss (dissipation) generation mechanisms. There is no direct method to measure entropy; hence the authors use an approach where the stagnation pressure and stagnation temperature are measured on the same probe. The stagnation, or 'total', pressure has been the subject of several of the authors' papers in the last few years. The more significant challenge was the time-resolved measurement of total temperature. The high Mach numbers present in the flows of interest lead to significant temperature gradients in the probe itself which contaminate this type of measurement. The paper describes a novel probe design along with a detailed heat transfer calculation and uncertainty analysis. The fluid mechanics members of the MST Editorial and Advisory Boards—T Fansler, J Foss, M Koochesfahani, I Marusic, S Morris, K Okamoto, F Scarano, E Tomita and M Wernet—considered all papers in the Fluid Mechanics section and the others that related to fluid mechanics.
