Field-testing of the ICHD-3 beta/proposed ICD-11 diagnostic criteria for migraine with aura
Authors: Li Dana , Christensen Anne F , Olesen Jes 
Published: November 2014

Introduction In 2013 the International Headache Society published the third International Classification of Headache Disorders beta-version, ICHD-3 beta. Its structure is identical to that of the present proposed version of the International Classification of Diseases (ICD-11), although slightly abbreviated to fulfill the needs of ICD-11. In the following, only ICHD-3 beta is mentioned, but findings regarding the validity of ICHD-3 beta categories are equally relevant to the forthcoming ICD-11. Here we field-tested the criteria for 1.2 migraine with aura (MA), 1.2.1 migraine with typical aura (MTA), 1.2.3 hemiplegic migraine, 1.2.2 migraine with brainstem aura, and the alternative criteria A1.2 MA and A1.2.1 MTA. Methods Clinical characteristics were systematically and prospectively collected from patients with 1.2.1 MTA, 1.2.4 familial hemiplegic migraine (FHM), 1.2.5 sporadic hemiplegic migraine (SHM) and 1.2.6 basilar-type migraine according to ICHD-2 in a cross-sectional study design. A database of 2464 patients with 1.1 migraine without aura and 1.2 migraine with non-hemiplegic aura and a database of 252 hemiplegic migraine patients (1.2.4 FHM or 1.2.5 SHM) was collected. We used SPSS 20 for Windows 8.0 for the statistical analysis. Results All ICHD-2 patients fulfilled ICHD-3 beta criteria for 1.2 MA. The ICHD-3 beta criteria for 1.2.1 MTA were more sensitive than ICHD-2 and ICHD-3 beta alternative criteria; they resulted in fewer probable MA diagnoses. Too many patients fulfilled ICHD-2 and ICHD-3 beta criteria for 1.2.2 migraine with brainstem aura. ICHD-3 beta criteria for 1.2.4 FHM and 1.2.5 SHM both comply with ICHD-2. Conclusion The new criteria in ICHD-3 beta/proposed ICD-11 for 1.2 MA, 1.2.1 MTA, 1.2.3.1 FHM and 1.2.3.2 SHM have more desirable properties than ICHD-2 and the ICHD-3 beta alternative criteria. The criteria for 1.2.2 migraine with brainstem aura should be more restrictive.
Association of statin use and risk for severe headache or migraine by serum vitamin D status: A cross-sectional population-based study
Authors: Buettner Catherine , Burstein Rami 
Published: November 2014

Objective The objective of this article is to evaluate whether statin use and vitamin D status is associated with severe headache or migraine in a nationally representative sample. Methods We conducted a cross-sectional study of US individuals aged ≥40 years for whom information on statin use, serum 25-hydroxy vitamin D (25(OH)D), and self-reported severe headache or migraine had been collected. We calculated prevalence estimates of headache according to statin and 25(OH)D, and conducted adjusted logistic regression analyses stratified by the median 25(OH)D (≤57 and >57 nmol/l). Results Among 5938 participants, multivariable-adjusted logistic regression showed that statin use was significantly associated with a lower prevalence of severe headache or migraine (OR 0.67; 95% CI 0.46, 0.98, p = 0.04). We found a significant interaction between statin use and 25(OH)D with the prevalence of severe headache or migraine ( p for interaction = 0.005). Among participants who had serum 25(OH)D > 57 nmol/l, statin use was associated with a multivariable-adjusted odds ratio of 0.48 (95% CI 0.32, 0.71, p = 0.001) for having severe headache or migraine. Among those with 25(OH)D ≤ 57 nmol/l, no significant association was observed between statin use and severe headache or migraine. Conclusion Statin use in those with higher serum vitamin D levels is significantly associated with lower odds of having severe headache or migraine.

Published: November 2014

Introduction: Since the introduction of computed tomography pulmonary angiography, isolated subsegmental pulmonary embolism has become a commonly recognized clinical problem, but its clinical relevance remains unclear. The objective of the present study was to evaluate the extent to which the simplified Wells score discriminates between patients with varying levels of risk of complications after presenting with subsegmental pulmonary embolism. Materials and Methods: Retrospective cohort study. Patients included had subsegmental pulmonary embolism (1 or multiple emboli limited to subsegmental arteries). Primary explanatory variable was the simplified Wells score, categorized as high (>4) or low (≤4). The primary outcome was time to death or new venous thromboembolism. Kaplan-Meier techniques and Cox regression analysis were used to compare the survival experience of patients with high versus low Wells score with and without adjustment for active malignancy, age, Charlson score, previous venous thromboembolism, and previous major surgery in the last 30 days. Main Results: Seventy-nine patients with subsegmental pulmonary embolism were included. Patients with a high Wells score had a 4-fold increased risk of the composite outcome (hazard ratio = 4.2, 95% confidence interval [CI] = 2.0-8.9, P < .001). Other covariates significantly associated with increased risk in univariate analyses included active malignancy, a low serum albumin, and an increased Charlson score. In multivariate Cox regression analyses adjusting for these other factors, a high Wells score remained significant (hazard ratio 5.5, 95% CI 2.4-12.6, P < .001). Conclusion: High Wells score is associated with death or new venous thromboembolism during follow-up among patients with subsegmental pulmonary embolism. Clinical trial registration: ClinicalTrials.gov number, NCT01372514.

Published: November 2014

Objectives Diabetic kidney disease (DKD) is a frequent and serious complication in human diabetic patients, but data are limited in cats. This study was undertaken to assess whether diabetic cats are susceptible to DKD. Methods Kidney function was compared between 36 cats with diabetes mellitus (DM), 10 cats with chronic kidney disease (CKD) and 10 age-matched healthy cats by measuring routine kidney variables (serum creatinine [sCreat], serum urea [sUrea], urine specific gravity [USG], urinary protein:creatinine ratio [UPC]), urinary cystatin C:creatinine ratio and glomerular filtration rate (GFR). Urinary cystatin C (uCysC) was measured with a human particle-enhanced nephelometric immunoassay, validated to measure feline cystatin C, in all but two diabetic cats. GFR was evaluated by exo-iohexol clearance in 17 diabetic cats, all cats with CKD and all healthy cats. Results Diabetic cats had significantly (mean ± SD) lower sCreat (123 ± 38 vs 243 ± 80 µmol/l), sUrea (11 ± 3 vs 18 ± 7 mmol/l) and urinary cystatin C:creatinine ratio (6 ± 31 vs 173 ± 242 mg/mol), and a significantly higher USG (1.033 ± 0.012 vs 1.018 ± 0.006) and GFR (2.0 ± 0.7 vs 0.8 ± 0.3 ml/min/kg) compared with cats with CKD. Compared with healthy cats, diabetic cats only had significantly lower USG (1.033 ± 0.012 vs 1.046 ± 0.008). Proteinuria (UPC >0.4) was present in 39% of diabetic cats, in 30% of cats with CKD and in none of the healthy cats. However, the UPC did not differ statistically between the three groups. Conclusions and relevance Based on evaluation of routine kidney variables, GFR and uCysC as a tubular marker at a single time point, a major impact of feline DM on kidney function could not be demonstrated.
What Makes a Prime Minister Great?: A Leadership Trait Analysis of the effectiveness of British Prime Ministers from 1902 to 2004
Authors: Rohrer Samuel R. 
Published: November 2014

What role do the Leadership Trait Analysis (LTA) criteria projected by a British Prime Minister (PM) have on the perceived effectiveness of their time in office? In this paper, the analysis of 20th-century British PMs utilized automated at-a-distance content analysis and the LTA coding system to determine the conceptual complexity, ability to control events, and need for power scores projected by PMs. The impact these traits had on the perceived effectiveness of the totality of the PMs’ tenure in office, as measured by the 2004 MORI/University of Leeds survey, was then examined via one-tailed ordinary least squares regression. This project provides evidence that British PMs who project traits associated with the LTA measure regarding strong power motivation are significantly viewed as more effective while in office. These findings provide more than a novel historical profile of British PMs. The relationship between effective leadership and LTA traits could be utilized by political campaigns, especially given the introduction of prime ministerial debates, to portray a prime ministerial candidate as more politically effective than his/her competition.

Background: Health care workers (HCWs) seek, treat, and care for patients living with HIV/AIDS on a daily basis and thus face a significant risk to work-related infections. To assess the knowledge, attitude, and practices regarding occupational HIV exposure and protection among HCWs in low HIV prevalence areas of rural China. Methods: A cross-sectional questionnaire survey was carried out among all medical units in Pucheng County, Shaanxi, China. Results: Response rate of this study was 94%. The average overall knowledge score of HCWs was 10.9 of 21.0. Deficiencies in general, transmission, exposure, and protection knowledge were identified among HCWs at all levels. A high rate of occupational exposure (85%) and lack of universal precautions practice behavior were recorded. Significant predictors of universal precautions practice behavior were female sex, prior training, and greater knowledge about HIV/AIDS. Conclusion: Health care workers at various levels have inadequate knowledge on HIV/AIDS and do not practice universal precautions. Nurses and medical technicians at the county level faced more occupation risk than other HCWs. The key of AIDS training for different levels of HCWs should be distinguished.
The Politics and Pleasures of Historiographic Porn
Authors: Cather Kirsten 
Published: November 2014

This article considers the 1973 Nikkatsu Roman Porn film adaptation of a short story by Japanese literary giant Nagai Kafū, “Underneath the Papering of the Four-and-a-Half-Mat Room” (“Yojōhan fusuma no urabari”). This low-budget erotic film appeared in the international context of the “liberation” (or decriminalization) of pornography that had swept Europe by the early to mid-1970s and in the domestic context of a severe crackdown on such trends. At the time of the film's release, both the story and the studio were at the center of high-profile obscenity trials in Japan. In this essay, I examine how and why these contexts led the filmmaker to take considerable liberties in adapting the story, in particular its conspicuous incorporation of archival photographs that document the rise of Japanese militarism in the mid- to late Taishō period (1912–26). I argue that the insistent injection of such politically and formally radical content strove to legitimize the film and, by implication, also its source text, as politically and aesthetically defensible in both legal and artistic circles.
But because the film had to function in its generic context as well, as a studio-branded “porno,” I insist also on considering the pornographic efficacy of such a strategy. I ask: What is the effect of injecting stilled historical images into a genre famous instead for its lush color moving ones? What can such a strategy tell us about postwar historical memory, the relationship of politics to pornography and of still photographs to moving film images, and the nature of film adaptations and their literary source texts? This film offers an extreme-limit case that brings to the fore the tensions between economic and generic demands on the one hand, and juridic, aesthetic, and auteurist imperatives, on the other, that are inherent in any film production.
Imagining Reality as a Set of Chinese Boxes: An Interview with Matsumoto Toshio
Authors: Inoue Miyo , Kerner Aaron 
Published: November 2014

In this interview the Japanese avant-garde filmmaker and scholar, Toshio Matsumoto, discusses his creative practice, as well as his ideas about the complexities of representing reality, memory, and time. He has numerous short experimental works to his credit, and four feature-length narrative films including Bara no soretsu (Funeral Parade of Roses, 1969), Shura (Demons, 1971), Juroku-sai no senso (The War of the Sixteen-Year-Olds, 1973), and Dogura magura (Dogra Magra, 1988). He has contributed significantly to the critical study of film in Japan as well, writing among things Eizo no hakken (Discovery of the Image, 1963/2005), Hyogen no sekai (World of Expression, 1967), and Genshi no bigaku (Aesthetics of Illusion, 1976). Despite these many accomplishments, Matsumoto has gone largely unrecognized in US scholarship.
The conception and representation of reality, memory, and time are significant tropes in Matsumoto's films. Bara no soretsu, for instance, set in the gay district of Tokyo, freely shifts between various points in time, mixes narrative fiction and documentary, and allows for the intermingling of the actors' own personal memories and the memories of the characters that they are playing. Each actor effectively plays a character that is modeled after his or her own life. The film is loosely adapted from Alain Resnais's 1959 film Hiroshima mon amour and appropriates many of the elements in it, including, most significantly, haunting flashbacks from a repressed traumatic memory. It is also a recasting of the Oedipus narrative, which to one degree or another is also about memory. In all of Matsumoto's feature films, a character suffers from some form of delusion and/or trauma that materializes in a surging pulse—the spectral return of the repressed—and this manifests not only as plot elements but also in cinematic form (e.g., flashbacks, non-linear narrative structures, overlapping editing).
Although certainly not the first to reconceptualize narrative temporality, Bara no soretsu confounded film critics at the time; many assumed that Matsumoto didn't even know how to tell a story or how to edit a film. Audiences today, however, are quick to accept the playful interventions in narrative form. This interview introduces this filmmaker/scholar who, in many respects, was far ahead of his time, to the English-speaking world.
A study of the lived experiences of registered nurses who have provided end-of-life care within an intensive care unit
Authors: Holms Natalie , Milligan Stuart , Kydd Angela 
Published: November 2014

Background: End-of-life care (EOLC) in the intensive care unit (ICU) has received little attention in the literature in comparison to the considerable amount of existing literature available on EOLC in other areas of nursing. The ethos of the ICU is to preserve life, but as many patients die in this environment, EOLC should be an integral part of the ICU nurse's role. This qualitative study explored the experiences of ICU nurses who had provided EOLC to patients and their families. Method: Participants were purposively recruited within one local ICU (n=5). A semi-structured interview format was used to guide in-depth interviews. Findings: The themes identified from the interview analysis were; use of integrated care systems, communication, the environment, education and training, staff distress. Conclusions: The findings suggest that ICU nurses do not feel adequately prepared to give proficient EOLC. Those who felt more confident in EOLC had learned what to do over time. Appropriate training, support and improved communication between staff, patients and families is necessary for good EOLC in ICUs.

Published: November 2014

AbstractCorrosion inhibitors are extensively applied to prevent the corrosion of metals in maintenance and vehicles used by transportation agencies. The aim of this review is to examine the state of the corrosion inhibitors for the protection of various metals/alloys commonly used in maintenance equipment and vehicles and to identify cost-effective, high-performance corrosion inhibitors that may contribute to the preservation of equipment assets. The focus is placed on the metallic corrosion induced or aggravated by chlorides at ambient temperature and pressure and near-neutral pH (6–8).
The Influence of the Induced Ferrite and Precipitates of Ti-bearing Steel on the Ductility of Continuous Casting Slab
Authors: Qian Guoyu , Cheng Guoguang , Hou Zibing 
Published: November 2014

AbstractIn order to investigate the loss of the ductility of Ti-bearing ship plate steel under 1000 °C, where the ductility begins to reduce rapidly, so the hot ductility of Ti-bearing ship plate steel has been obtained using the Gleeble 1500 thermal-mechanical simulator and also the studies about the effect of grain boundary ferrite films and precipitates containing Ti on the ductility has been carried out. The result showed that the TiN particles precipitating at 950 °C with a larger size and smaller volume fraction cannot effectively suppress the occurrence of recrystallization and the ductility still retains at a high level, although R.A. value presents a certain degree of decline compared with 1000 °C. A large number of smaller Ti(C,N) particles precipitate at 900 °C and can induce the formation of a very small amount of fine grain boundary ferrite, which deteriorates the adhesion strength of the grain boundary, so the R.A. value rapidly reduces to less than 50%. When the temperature falls to close Ae3 (827 °C), the amount of the grain boundary ferrite films increase due to the ferrite phase transformation, but the ferrite film thickness becomes more uneven at the same time, which results in the increase of strain concentration and plays a leading role in causing the decrease of ductility, so the R.A. value has been kept less than 40% as the temperature cooling to 800 °C from 850 °C. When the temperature further decreases, the ductility starts to recover due to the increase of average ferrite film thickness to a greater degree which greatly reduces the strain concentration of the grain boundary.

AbstractA 14-year-old female with classical congenital adrenal hyperplasia because of 21-hydroxylase deficiency underwent bilateral adrenalectomy at 6 years of age as a result of poor hormonal control. Because the patient was adrenalectomized, extra adrenal androgen production was suspected. Imaging studies including pelvic ultrasound and pelvic magnetic resonance imaging (MRI) were obtained to evaluate for adrenal rest tumors of the ovaries. Abdominal MRI was obtained to evaluate for residual adrenal tissue. A cystic lesion arising from her right ovary suspicious for ovarian neoplasm was noted on pelvic MRI. Right salpingo-oophorectomy was performed and histopathological examination revealed ovarian serous adenocarcinoma, low-grade, and well-differentiated. Tumor marker CA-125 was elevated and additional ovarian cancer staging workup confirmed stage IIIC due to one lymph node positive for carcinoma. The patient then developed a large left ovarian cyst, which led to a complete total abdominal hysterectomy and removal of the left ovary and fallopian tube. Pathology confirmed ovarian serous adenocarcinoma with microscopic focus of carcinoma in the left ovary. After numerous complications, the patient responded well to chemotherapy, CA-125 levels fell and no evidence of carcinoma was observed on subsequent imaging. To our knowledge, this is the first reported case of an ovarian serous adenocarcinoma in a patient with CAH. Although rare, we propose that the ovaries were the origin of androgen production and not residual adrenal tissue. The relationship between CAH and ovarian carcinomas has yet to be established, but further evaluation is needed given the poor survival rate of high-grade serous ovarian carcinoma.
Noncausality and inflation persistence
Authors: Lanne Markku 
Published: November 2014

AbstractWe use noncausal autoregressions to examine the persistence properties of quarterly US consumer price inflation from 1970:1 to 2012:2. These nonlinear models capture the autocorrelation structure of the inflation series as accurately as their conventional causal counterparts, but they allow for persistence to depend on the size and sign of shocks to inflation as well as the inflation rate. Inflation persistence has decreased since the early 1980s, after which persistence is also greater following small and negative shocks than large and positive ones. At high levels of inflation, shocks are absorbed more slowly before the early 1980s and faster thereafter compared to low levels of inflation.

Abstract
Objectives: A simple, quick and low cost HPLC-UV method for assay of meloxicam in plasma and pharmaceutical dosage forms was developed.
Methods: Separation and assay of meloxicam, using a simple reverse phase HPLC-UV method was achieved using an Agilent Zorbax SB C18 column, with methanol and 1% aqueous solution of glacial acetic acid as mobile phase. Elution was performed with composition gradient, meloxicam being detected at 355 nm with a 5 minutes analysis time. The method was tested on human plasma and pharmaceutical dosage forms.
Results: The retention time of the meloxicam was 3,7 minutes. Regression analysis showed good linearity, with correlation coefficient R= 0,9997; linear regression equation: y = 206,1x -77,5 over the 20-2000 ng/ml concentration range. Limit of detection was determined to be 5 ng/ml and limit of quantification was set at 15 ng/ml. The recovery of the analyte in human plasma was low: 30,50%, however it was reproducible, with a coefficient of variation of 4,83%. The analysis of the tablets resulted in a 85,82% of meloxicam compared to the declared concentration.
Conclusions: The method proposed is quick, simple and adequate for detecting the meloxicam in human plasma. Although the recovery rate was low, it was reproducible, which leads to the fact, that improving extraction procedure can optimize the method.
