Published: October 2019

Introduction: Chronic spontaneous urticaria (CSU) which develops without a known stimulation is defined as the occurrence of spontaneous wheals, angioedema or both for longer than six weeks. Infections, autoimmunity, food intolerance and internal parasitic infections are supposed to be underlying causes of CSU. The aim of this study was to evaluate the intestinal parasites in children and adult patients diagnosed as CSU, to determine the frequency of parasites in chronic urticaria, and to compare these patients with healthy demographic control groups.
Methodology: Seventy six children and 38 adult patients with CSU were examined in terms of parasitic infections. The patients whom parasites were detected received anti-parasitic therapy and the improvements in CSU symptoms were evaluated. Stool samples were examined with direct microscopic examination (native-lugol), stool concentration and trichrome staining methods.
Results: In pediatric patient group, 18.4% (n = 14) of the stool samples were positive for Blastocystis sp., 2.6% (n = 2), Dientamoeba fragilis and 1.3% (n = 1), Giardia duodenalis. In adult patient group, Blastocystis sp. was detected in 18.4% (n = 7) of the stool samples. Anti-parasitic therapy yielded substantial improvement in urticaria symptoms in 57.1% of pediatric and 60.0% of adult patients.
Conclusions: Blastocystis sp. and D. fragilis may play a role in chronic urticaria which seriously disrupts the patient's quality of life. Parasitic infections should not be neglected in patients with cutaneous manifestations.

Introduction: The goal of this study was to identify the profile of genital tract infections and their relationship with clinical and demographic parameters as well as tubal diseases among infertile women in Vietnam.
Methodology: In this cross-sectional descriptive study, we enrolled 597 women undergoing infertility treatment at the Center for Reproductive Endocrinology & Infertility, Hue University Hospital, Vietnam. All of the study participants were interviewed and examined by a gynecologist. Consecutive tests were then conducted including direct microscopy examination (wet mount and Gram stain), vaginal culture, polymerase chain reaction (PCR) for chlamydia diagnosis from a cervical canal swab, and a blood test for syphilis detection. A hysterosalpingogram (HSG) was carried out to examine the uterine cavity and Fallopian tubes.
Results: A gynecologic infection was diagnosed in 43.4% (259/597) of the infertile women. Bacterial vaginosis was the most common condition at 19.6%of the cases. Candida spp., Chlamydia trachomatis, and Trichomonas vaginalis infections accounted for 17.4%, 3.7%, and 0.3%, respectively. Normal HSG results accounted for 87.4% of the women while 5.5% had 2-sided tubal occlusions, 5.4% had 1-sided tubal occlusions, 1.0% had 1-sided hydrosalpinx, and 0.7% had 2-sided hydrosalpinx. There was no significant association between tubal diseases and current infections; however, aerobic vaginitis increased the risk of tubal diseases by 2.4 times.
Conclusions: A marked proportion of infertile Vietnamese women have genital tract infections that can significantly influence their reproductive function and performance. These infections should be routinely screened and treated properly to prevent their consequences, such as infertility, which is especially important in developing countries.
Threshold value of the anti-HCV test in the diagnosis of HCV infection
Authors: Kirişci Özlem , Calıskan Ahmet 
Published: October 2019

Introduction: In the diagnosis of hepatitis C virus (HCV) infection, the first step is screening for anti-HCV antibodies, and positive results are generally confirmed with nucleic acid amplification tests. Recent studies have reported that more compatible results have been obtained with the HCV RNA test using signal to cut-off (S/Co) values >1, which are the routine reactivity threshold for the anti-HCV enzyme immunoassay (EIA) test. The aim of this study was to determine the most appropriate S/Co value for the anti-HCV test, predicting HCV infection.
Methodology: Comparisons were made between results of 559 patients who underwent anti-HCV with ECLIA method and HCV RNA tests with real-time polymerase chain reaction (PCR) method. By accepting the HCV-RNA test as the gold standard for HCV infection, the sensitivity, specificity and predictive values of the ECLIA test were determined and statistical “receiver operating characteristic” (ROC) analysis was applied to determine the most appropriate threshold.
Results: Between January 2013 and April 2018, a total of 81,203 serum samples were examined. Of 559 anti-HCV positive patients, HCV RNA positivity was determined in 214 (38.2 %). According to the ROC analysis results, the most appropriate S/Co value was determined as 12.27, at which sensitivity was 94.4 %, and specificity 97.4 %. The positive and negative predictive values were calculated at the high rate of 95.7% and 96.6% respectively.
Conclusions: The results of this study investigating the anti-HCV reactivity values which could be used in the diagnosis of HCV infection determined the most appropriate value to be 12.27.
La construction de nouvelles relations entre contrôleur de gestion et managers opérationnels dans le contexte d’un contrôle de gestion décentralisé
Authors: Ennajem Cécile 
Published: October 2019

Dans le cadre d’un contrôle de gestion décentralisé, nous étudions l’évolution du rôle du contrôleur de gestion sous l’angle de ses relations interpersonnelles avec les managers opérationnels. Les résultats présentés sont issus de recherches-interventions menées dans trois entreprises. Nous mettons en évidence trois nouvelles missions du contrôleur de gestion : conseiller, avec un rôle d’assistant et d’interface entre les différentes catégories d’acteurs ; médiateur, comme dans la littérature en contrôle de gestion, qui fournit des chiffres, des informations et des études pour justifier les choix de la direction générale, mais qui aide aussi à remettre en question les raisonnements, les certitudes et postulats du décideur ; animateur auprès de la Direction générale et des managers opérationnels, car il permet d’améliorer la qualité des relations internes, de la coopération opérationnels-fonctionnels et l’utilisation des outils de contrôle de gestion.
Acceptation ou refus de la vidéo-protection par les collaborateurs : influence des facteurs de contingence lors de la mise en place de la vidéo-protection
Authors: Diard Caroline 
Published: October 2019

La vidéo-protection est un mode de contrôle choisi par les entreprises afin de protéger les personnes et les biens. La revue de littérature fait apparaître la notion d’acceptation d’une technologie (Fishbein et Ajzen, 1975, Davis, 1989), de « mandatory » (Chang, 2010), de contingence (Mintzberg, 1982 ; Woodward 1965). L’objet de cet article est d’étudier l’influence des facteurs de contingence dans l’acceptation ou non de la vidéo-protection. Cette contribution s’appuie sur les résultats d’une étude qualitative. Quel rôle jouent les facteurs de contingence dans l’acceptation ou le refus de la vidéo-protection par les collaborateurs ?
Le pilotage de l’innovation : des contrôles et des hommes
Authors: Batac Julien , Maymo Vincent 
Published: October 2019

Si le modèle des leviers de contrôle de Simons (1995) permet d’étudier l’influence du contrôle sur la stratégie et l’innovation, il néglige le caractère politique de l’innovation (Henderson et Clark, 1990) et l’influence des jeux d’acteurs dans l’articulation entre systèmes de contrôle (Tessier et Otley, 2012). Au travers d’une étude de cas réalisée entre 2000 et 2013 au sein d’une banque de détail, nous montrons que le pilotage de l’innovation est influencé par les stratégies individuelles des managers et ne se limite pas une relation univoque dans le sens « contrôle-innovation ».

Avec l’émergence du web 2.0 et des réseaux sociaux, le marketing est entré dans l’ère de l’hyper mesurabilité. Cependant une question demeure, quelles sont les stratégies d’alliance les plus efficaces sur les réseaux sociaux ? Pour répondre à cette question, une netnographie de 6 communautés virtuelles totalisant 554 725 fans sur Facebook a été réalisée. Les principaux résultats montrent que le parrainage d’athlètes est le plus performant au regard des commentaires et du nombre de « j’aime » générés. Aussi une approche qualitative a permis de mettre en lumière des réactions affectives de joie et de peur associées au parrainage.
Réflexion sur le cadre théorique pour l’intégration des normes qualité de la formation professionnelle dans les organismes de formation
Authors: Bensimhon Larry , Miel Yannick 
Published: October 2019

La formation professionnelle continue est de manière inédite soumise à une normalisation de la qualité. Le cadre normatif de la qualité qui en découle s’impose à tous les organismes de formation sous peine d’être privés de leur principal système de financement : les fonds de la formation professionnelle. L’objectif de cet article est d’explorer le cadre théorique sur lequel peut s’appuyer l’étude de ce phénomène afin de travailler sur l’émergence d’une méthode d’accompagnement qui permettrait aux organismes de formation de valoriser l’intégration des normes qualité.
Quel risque pour le lanceur d’alerte ? L’accusation de déloyauté
Authors: Cailleba Patrice 
Published: October 2019

Le premier risque que court le lanceur d’alerte est l’accusation de déloyauté. Lorsque le lanceur d’alerte interne met à mal la réputation de son employeur via son alerte, ce dernier essaie de le déconsidérer en mettant à jour son manque de « bonne foi ». Dans cet article, nous nous interrogerons sur l’importance en filigrane de la loyauté en droit français avant d’examiner les différents types de loyauté. Puis, nous considérerons le moyen de dépasser ce risque d’accusation. Ceci passe par une forme de « loyauté rationnelle » qui s’impose d’elle-même au « whistle-blower », quel qu’en soit le prix.

Abstract
Purpose: The purpose of our study was to conduct a chemical analysis of extracranial foreign bodies (FBs) causing artifacts in cranial magnetic resonance imaging (MRI) and to investigate the association between chemical composition, magnetic susceptibility, and artifact size. Materials and Methods: A total of 12 patients were included in the study. The FBs responsible for the artifacts were visualized using cranial computed tomography (CT). Artifact-causing FBs were removed from the scalps of 10 patients and analyzed using scanning electron microscope with energy dispersive spectroscopy (SEM-EDS), X-ray diffraction spectroscopy (X-RD), and Fourier-transform infrared spectroscopy (FT-IR). The magnetic susceptibility of the samples was determined using the reference standard material MnCl2.6H2O. The volume of the MRI artifacts was measured in cubic centimeters (cm3). Results: EDS results demonstrated that the mean Fe ratio was 5.82% in the stone samples and 0.08% in the glass samples. Although no phase peaks were detected in the X-RD spectra of the glass samples, peaks of Fe2O3, Al2Ca (SiO4) were detected in the X-RD spectra of the stone samples. The FT-IR spectra revealed metal oxide peaks corresponding to Fe, Al, in the stone samples and peaks confirming Al2SiO5and Na2SiO3structures in the glass samples. The mean volumes of the MRI artifacts produced by the stone and glass samples were 5.9 cm3 and 2.5 cm3, respectively. Conclusions: Artifacts caused by extracranial FBs containing metal/metal oxide components are directly associated with their chemical composition and the artifact size are also related to element composition and magnetic susceptibility.
Left atrial isomerism associated with aneurysmal enlargement of right atrial appendage: A case report with literature review
Authors: Agarwal Prateek , Agarwal Rajesh Kumar 
Published: October 2019

AbstractWe present a prenatally diagnosed case of heterotaxy syndrome (HS) in which left atrial isomerism (LAI) was associated with an aneurysmal enlargement of the right atrial appendage (RAA). Although LAI is usually associated with complex cardiac and extracardiac anomalies, the association of LAI and right atrial appendage aneurysm (RAAA) is exceptional. Congenital RAAA itself is an idiopathic, very rare cardiac anomaly characterized by the enlargement of the appendage in the absence of any other cardiac or extra-cardiac defect. The prognosis of the heterotaxy is poor with associated major cardiac malformations and even cases with minor cardiac anomalies are at risk postnatally for complications like biliary atresia, intestinal rotational abnormalities, and immune disorders. In this case, the prenatal diagnosis of the isomerism was mainly based on the abnormalities of caval veins. Although no typical complex cardiac anomaly was present, the HS was associated with biliary atresia, polysplenia, and malrotation of the gut. Associated RAAA further imposed an additional risk of complications such as tachyarrhythmias, thromboembolic events, and aneurysmal rupture.

Schizophrenia—An Overview
Authors: McCutcheon Robert A. , Reis Marques Tiago , Howes Oliver D. 
Published: October 2019

ImportanceSchizophrenia is a common, severe mental illness that most clinicians will encounter regularly during their practice. This report provides an overview of the clinical characteristics, epidemiology, genetics, neuroscience, and psychopharmacology of schizophrenia to provide a basis to understand the disorder and its treatment. This educational review is integrated with a clinical case to highlight how recent research findings can inform clinical understanding.ObservationsThe first theme considered is the role of early-life environmental and genetic risk factors in altering neurodevelopmental trajectories to predispose an individual to the disorder and leading to the development of prodromal symptoms. The second theme is the role of cortical excitatory-inhibitory imbalance in the development of the cognitive and negative symptoms of the disorder. The third theme considers the role of psychosocial stressors, psychological factors, and subcortical dopamine dysfunction in the onset of the positive symptoms of the disorder. The final theme considers the mechanisms underlying treatment for schizophrenia and common adverse effects of treatment.Conclusions and RelevanceSchizophrenia has a complex presentation with a multifactorial cause. Nevertheless, advances in neuroscience have identified roles for key circuits, particularly involving frontal, temporal, and mesostriatal brain regions, in the development of positive, negative, and cognitive symptoms. Current pharmacological treatments operate using the same mechanism, blockade of dopamine D2 receptor, which contribute to their adverse effects. However, the circuit mechanisms discussed herein identify novel potential treatment targets that may be of particular benefit in symptom domains not well served by existing medications.

AbstractObjectiveThe aging brain undergoes several changes, including reduced vascular, structural, and dopamine (DA) system integrity. Such brain changes have been associated with age‐related cognitive deficits. However, their relative importance, interrelations, and links to risk factors remain elusive.MethodsThe present work used magnetic resonance imaging and positron emission tomography with 11C‐raclopride to jointly examine vascular parameters (white‐matter lesions and perfusion), DA D2‐receptor availability, brain structure, and cognitive performance in healthy older adults (n = 181, age: 64–68 years) from the Cognition, Brain, and Aging (COBRA) study.ResultsCovariance was found among several brain indicators, where top predictors of cognitive performance included caudate and hippocampal integrity (D2DR availability and volumes), and cortical blood flow and regional volumes. White‐matter lesion burden was negatively correlated with caudate DA D2‐receptor availability and white‐matter microstructure. Compared to individuals with smaller lesions, individuals with confluent lesions (exceeding 20 mm in diameter) had reductions in cortical and hippocampal perfusion, striatal and hippocampal D2‐receptor availability, white‐matter microstructure, and reduced performance on tests of episodic memory, sequence learning, and processing speed. Higher cardiovascular risk as assessed by treatment for hypertension, systolic blood pressure, overweight, and smoking was associated with lower frontal cortical perfusion, lower putaminal D2DR availability, smaller grey‐matter volumes, a larger number of white‐matter lesions, and lower episodic memory performance.InterpretationTaken together, these findings suggest that reduced cardiovascular health is associated with poorer status for brain variables that are central to age‐sensitive cognitive functions, with emphasis on DA integrity.
Outlier accommodation in moving‐horizon state estimation: A risk‐averse performance‐specified approach
Authors: Aghapour Elahe , Farrell Jay A. 
Published: October 2019

SummaryThis paper presents a novel state estimation approach for linear dynamic systems when measurements are corrupted by outliers. Since outliers can degrade the performance of state estimation, outlier accommodation is critical. The standard approach combines outlier detection utilizing Neyman‐Pearson (NP) type tests with a Kalman filter (KF). This approach ignores all residuals greater than a designer‐specified threshold. When measurements with outliers are used (ie, missed detections), both the state estimate and the error covariance matrix become corrupted. This corrupted state and covariance estimate are then the basis for all subsequent outlier decisions. When valid measurements are rejected (ie, false alarms), potentially using the corrupted state estimate and error covariance, measurement information is lost. Either using invalid information or discarding too much valid information can result in divergence of the KF. An alternative approach is moving‐horizon (MH) state estimation, which maintains all recent measurement data within a moving window with a time horizon of length L. In MH approaches, the number of measurements available for state estimation is affected by both the number of measurements per time step and the number of time steps L over which measurements are retained. Risk‐averse performance‐specified (RAPS) state estimation works within an optimization setting to choose a set of measurements that achieves a performance specification with minimum risk of outlier inclusion. This paper derives and formulates the MH‐RAPS solution for outlier accommodation. The paper also presents implementation results. The MH‐RAPS application uses Global Navigation Satellite Systems measurements to estimate the state of a moving platform using a position, velocity, and acceleration model. In this application, MH‐RAPS performance is compared with MH‐NP state estimation.
Direct Observation of Conductive Polymer Induced Inversion Layer in n‐Si and Correlation to Solar Cell Performance

Published: October 2019

AbstractHeterojunctions formed by ultrathin conductive polymer [poly(3,4‐ethylenedioxythiophene): poly(styrenesulfonate)—PEDOT:PSS] films and n‐type crystalline silicon are investigated by photoelectron spectroscopy. Large shifts of Si 2p core levels upon PEDOT:PSS deposition provide evidence that a dopant‐free p–n junction, i.e., an inversion layer, is formed within Si. Among the investigated PEDOT:PSS formulations, the largest induced band bending within Si (0.71 eV) is found for PH1000 (high PEDOT content) combined with a wetting agent and the solvent additive dimethyl sulfoxide (DMSO). Without DMSO, the induced band bending is reduced, as is also the case with a PEDOT:PSS formulation with higher PSS content. The interfacial energy level alignment correlates well with the characteristics of PEDOT:PSS/n‐Si solar cells, where high polymer conductivity and sufficient Si‐passivation are also required to achieve high power conversion efficiency.
