Abstract
The numerical simulation of thermalhydraulic processes in nuclear power plants requires very accurate and extremely fast algorithms for calculating the thermophysical properties of water and steam. In order to provide such algorithms, the International Association for the Properties of Water and Steam (IAPWS) has adopted the new “IAPWS Guideline on the Fast Calculation of Steam and Water Properties with the Spline-Based Table Look-Up Method (SBTL)”. In this article, the SBTL method is applied to property functions of specific volume and specific internal energy (v,e) based on the scientific formulation IAPWS-95 and the latest IAPWS formulations for transport properties. From the newly generated SBTL functions, thermodynamic and transport properties as well as their derivatives and inverse functions are calculable in the fluid range of state for pressures up to 100 MPa and for temperatures up to 1273 K, including the metastable liquid and the metastable vapor regions. The SBTL functions reproduce the underlying formulations with an accuracy of 10–100 ppm and significantly reduced computing times. The SBTL method has been implemented into the nuclear reactor system safety analysis code RELAP-7 [2] to consider the real fluid behavior of water and steam in a novel 7-equation two-phase flow model.

Published: July 2017

Background: Subjective cognitive complaints (SCCs) may be an early marker of prodromal Alzheimer’s disease. Objectives: Using a 10-item yes/no SCCs questionnaire (Le Questionnaire de Plainte Cognitive [QPC]), we evaluated the prevalence and distribution of SCCs in cognitively healthy Czech older adults and examined total score and specific QPC items in relation to depressive symptomology and cognitive performance. Methods: A sample of 340 cognitively healthy older community-dwelling volunteers aged 60 or older from the third wave of the longitudinal project National Normative Study of Cognitive Determinants of Healthy Aging, who underwent a comprehensive neuropsychological assessment and completed the QPC and the 15-item Geriatric Depression Scale (GDS-15). Regression analysis was controlled for age when GDS-15 was the outcome and for age and GDS-15 with cognitive domains as the outcome. Results: 71% reported 1 + SCCs, with prevalence of individual complaints ranging from 4% to 40%. The number of SCCs was associated with GDS-15 ( p < 0.001). Personality change (p < 0.001) and Limitation in daily activities (p = 0.002) were significantly associated with higher GDS-15 score and Spatial orientation difficulties (p = 0.019) and Impression of worse memory in comparison to peers ( p = 0.012) were significantly associated with lower memory performance. Conclusions: We identified some cognitive complaints that were very common in our sample. Overall, a higher number of SCCs in well cognitively functioning individuals was most closely related to depressive symptomatology, while some specific complaints reflected lower memory performance and should be considered when screening for people at risk of cognitive decline.
The Potential Cardiovascular Benefits of Low-Glucose Degradation Product, Biocompatible Peritoneal Dialysis Fluids: A Review of the Literature

Published: July 2017

Cardiovascular mortality in the end-stage renal disease (ESRD) population remains the leading cause of death. Targeting traditional cardiovascular risk factors has proven unsuccessful in this patient population, and therefore attention has turned to risk factors related to chronic kidney disease (CKD). The toxicity of high-glucose peritoneal dialysis (PD) solutions has been well documented. The breakdown of glucose into glucose degradation products (GDP) and advanced glycation end-products (AGE) has the ability to alter cell viability and cause premature apoptosis and is strongly correlated with interstitial fibrosis and microvascular sclerosis. Biocompatible solutions have been introduced to combat the hostile milieu to which PD patients are exposed. Given the considerable cardiovascular burden for PD patients, little is known about the cardiovascular impact the new biocompatible solutions may have. This review analyzes the existing literature regarding the mechanisms through which low-GDP solutions may modulate cardiovascular risk. Interventions using low-GDP solutions have provided encouraging changes in structural cardiovascular measures such as left ventricular mass (LVM), although metabolic changes from reduced GDP and AGE exposure yield inconclusive results on vascular remodelling. It is thought that the local effects of reduced glucose exposure may improve membrane integrity and therefore fluid status. Further research in the form of a robust randomized controlled trial should be carried out to assess the true extent of the cardiovascular benefits these biocompatible solutions may hold.

Objective: To identify relevant evidence to the peculiarities of nursing care to women in situation of unsafe abortion.
Method: This is a survey of integrative review of literature, where the databases used were LILACS, BDENF, MEDLINE and SCOPUS. The data collection occurred during the months of September and October 2016, articles were in Portuguese, English and Spanish, from 2006 to 2016. The sample was composed of 14 studies.
Results: Studies have shown that nursing care is carried out in a technicist and without quality service; contrary to the norms of the Code of Ethics for nurses. There were willing two thematic categories: reasons that led the women to practice unsafe abortion and the nursing care provided to women in a situation of abortion.
Conclusion: Trials, prejudice, religiosity and moral values of nurses, contribute to the precariousness of quality assistance to these women.

La multiplicité des connaissances et le tremblement des institutions
Authors: Rabeharisoa Vololona 
Published: July 2017

Ces dernières années, l’engagement des associations de malades – et plus largement des groupes concernés par un problème impliquant des savoirs scientifiques – dans la production de connaissances est devenu un thème classique en sciences sociales. Les connaissances expérientielles que produisent ces associations et ces groupes constituent un défi pour les institutions scientifiques. Cet article propose quelques pistes que les chercheurs intéressés par l’anthropologie des connaissances pourraient explorer pour comprendre comment les institutions scientifiques se rendent (ou non) sensibles à ces connaissances expérientielles, et aux transformations que ces connaissances pourraient induire sur la gouvernance de la recherche et de l’innovation.
Innovation ouverte et « Living labs » : production et traduction d’un modèle européen
Authors: Ark Ceren , Smyrl Marc 
Published: July 2017

Résumé Parmi les mesures mises en avant par l’Union européenne pour encourager l’innovation technologique et l’emploi, le Open Innovation Strategy and Policy Group (OISPG), hébergé par la Commission européenne, a défini un modèle d’innovation « centrée sur l’utilisateur ». L’association European Network of Living Labs (ENoLL), qui relève indirectement de l’Union européenne, est chargée de la labellisation des living labs, unités publiques ou privées de recherche et développement adoptant cette méthode. L’analyse des effets de la dynamique institutionnelle entre ces trois instances fait ressortir l’évolution imprévue du modèle lui-même. Conçue comme un moyen pour atteindre les buts fixés par l’Union européenne, l’innovation centrée sur l’utilisateur est devenue une fin en soi, applicable à des questions et projets divers.
La production du « vrai musulman » par l’organisation des Frères musulmans égyptiens : fidélité et dissidences
Authors: Néfissa Sarah Ben 
Published: July 2017

L’encadrement de la jeunesse est une activité centrale de l’organisation des Frères musulmans égyptiens, car leur vision de la réforme politique est pensée comme un résultat de la réforme religieuse de l’individu. L’article se propose d’analyser les modalités de leur action éducative. Il se fonde sur la littérature de la confrérie explicitant les principes éducatifs de cette dernière, sur des documents internes organisant leur mise en œuvre et, enfin, sur les témoignages publiés par des ex-jeunes Frères musulmans. La production du « vrai musulman » repose autant sur la dimension affective produite par l’organisation que sur la surveillance et le contrôle des individus. L’article met l’accent sur l’importance du facteur culturel comme ressource principale du désengagement.
L’accès aux services en réseau par le microcrédit : un palliatif au retrait de l’État et du service public ?
Authors: Isaurralde Magdalena 
Published: July 2017

En Argentine, à l’image d’autres pays latino-américains, la fourniture de services collectifs a progressivement été intégrée dans les fonctions étatiques à travers la construction des « monopoles naturels ». Ces monopoles n’ont pourtant pas atteint la couverture totale du territoire. Face à la croissance de l’habitat informel aux marges des grandes métropoles, comme Buenos Aires, et dans le cadre de mutations profondes de l’économie des services, comment garantir l’accès aux services de base pour les populations défavorisées ? Le microcrédit pour l’accès aux services, comme l’énergie, peut-il être un instrument idoine pour faciliter le raccordement des ménages pauvres à des réseaux d’infrastructure ? Cet article interroge l’efficacité de l’utilisation du microcrédit pour financer les raccordements domiciliaires aux réseaux d’infrastructure à travers son utilisation dans le cadre d’un projet d’extension de gaz à Buenos Aires, en Argentine.
Inflammasome and Fas-Mediated IL-1β Contributes to Th17/Th1 Cell Induction in Pathogenic Bacterial Infection In Vivo

Abstract
CD4+ Th cells play crucial roles in orchestrating immune responses against pathogenic microbes, after differentiating into effector subsets. Recent research has revealed the importance of IFN-γ and IL-17 double-producing CD4+ Th cells, termed Th17/Th1 cells, in the induction of autoimmune and inflammatory diseases. In addition, Th17/Th1 cells are involved in the regulation of infection caused by the intracellular bacterium Mycobacterium tuberculosis in humans. However, the precise mechanism of Th17/Th1 induction during pathogen infection is unclear. In this study, we showed that the inflammasome and Fas-dependent IL-1β induces Th17/Th1 cells in mice, in response to infection with the pathogenic intracellular bacterium Listeria monocytogenes. In the spleens of infected wild-type mice, Th17/Th1 cells were induced, and expressed T-bet and Rorγt. In Pycard−/− mice, which lack the adaptor molecule of the inflammasome (apoptosis-associated speck-like protein containing a caspase recruitment domain), Th17/Th1 induction was abolished. In addition, the Fas-mediated IL-1β production was required for Th17/Th1 induction during bacterial infection: Th17/Th1 induction was abolished in Fas−/− mice, whereas supplementation with recombinant IL-1β restored Th17/Th1 induction via IL-1 receptor 1 (IL-1R1), and rescued the mortality of Fas−/− mice infected with Listeria. IL-1R1, but not apoptosis-associated speck-like protein containing a caspase recruitment domain or Fas on T cells, was required for Th17/Th1 induction, indicating that IL-1β stimulates IL-1R1 on T cells for Th17/Th1 induction. These results indicate that IL-1β, produced by the inflammasome and Fas-dependent mechanisms, contributes cooperatively to the Th17/Th1 induction during bacterial infection. This study provides a deeper understanding of the molecular mechanisms underlying Th17/Th1 induction during pathogenic microbial infections in vivo.

Published: July 2017

Abstract
Purpose: To determine whether or not there were any differences in the measurement techniques used by orthopedic and radiology specialists in the evaluation of magnetic resonance (MR) images for the diagnosis of patella alta in adolescents. Materials and Methods: Evaluations were performed by three orthopedic specialists (Group I) and three radiology specialists (Group II) regarding the presence of patella alta in 40 adolescents cases using the Insall–Salvati, Caton–Deschamps, Blackburne–Peel, and modified Insall–Salvati indices on MR images obtained to diagnose patellar instability. Results: The Fleiss Kappa conformity levels for Insall–Salvati, Caton–Deschamps, Blackburne–Peel, and modified Insall–Salvati measurements were 0.531, 0.559, 0.246, and 0.272, respectively, in Group I, and 0.699, 0.346, 0.516, and 0.394, respectively, in Group II. Conclusion: The radiology specialists were found to have greater conformity in the evaluation of all patella alta indices, which was probably due to their greater familiarity with radiological measurements than that of the orthopedic specialists.
Cystic lesions of the pancreatico-biliary tree: A schematic MRI approach
Authors: Halankar Jaydeep , Jhaveri Kartik , Metser Ur 
Published: July 2017

AbstractAlthough a common occurrence, cystic lesions of the pancreatico-biliary tree (PBT) may pose a diagnostic dilemma because they encompass a large number of neoplastic and benign processes with varied clinical symptoms. Knowledge of lesion classification and characterization are essential in making an accurate prospective diagnosis. This is necessary for identifying clinically significant cystic masses, which at times may require invasive intervention from indolent, nonneoplastic lesions, for which surveillance may suffice. Today, there is an arsenal of modalities for assessing the PBT, however, magnetic resonance imaging (MRI) remains at the forefront for characterizing cystic morphology and fluid content, internal septations, solid component, enhancement patterns, as well as assessing the surrounding normal structures. This pictorial review aims to review the spectrum of MRI features, which will aid in the differential diagnoses of cystic lesions of the PBT and mimickers, enabling the radiologist to reach a more confident diagnosis.

Abstract
Aims: To assess the severity of acute pancreatitis (AP) using computed tomography (CT) severity index (CTSI) and modified CT severity index (MCTSI), to correlate with clinical outcome measures, and to assess concordance with severity grading, as per the revised Atlanta classification (RAC). Materials and Methods: In this prospective study approved by the Institutional Review Board (November 2014 to March 2016), sixty patients with AP (as per the RAC definition) underwent contrast-enhanced computed tomography (CECT) 5–11 days (median 6 days) after symptom onset. Two radiologists, blinded to clinical parameters, independently assessed CTSI and MCTSI (differences were resolved by consensus). Clinical outcome parameters included duration of stay in the hospital and intensive care unit (ICU), presence of persistent organ failure (OF), evidence of infection, need for intervention, and mortality. Results: We included 60 cases [36 males, age range 19–65 (mean 37) years]. As per the RAC, 26 patients had mild AP, 12 moderately severe, and 22 severe AP. According to CTSI and MCTSI, mild, moderate, and severe cases were 27 (45%), 19 (31.7%), 14 (23.3%) and 24 (40%), 10 (16.7%), 26 (43.3%), respectively. MCTSI was concordant with the RAC grading in 54 (90.0%), CTSI was concordant in 47 (78.3%), and both were concordant in 43 (71.7%) cases. Area under the receiver-operating characteristic (ROC) curves (AUROC) was compared by the Hanley and McNeil method. Both CTSI and MCTSI were significantly associated with outcome parameters (P &lt; 0.001), except duration of ICU stay. Sensitivity, specificity, positive predictive value (PPV), and accuracy of CTSI for detecting moderate/severe disease were 97.1%, 100%, 100%, and 98.3% respectively, and of MCTSI were 100%, 92.3%, 94.4%, and 96.7% respectively. Conclusion: Both CTSI and MCTSI showed significant correlation with clinical outcome parameters, and good concordance with RAC grading of severity. MCTSI showed a higher sensitivity but lower specificity than CTSI in differentiating mild from moderate/severe AP.

Published: July 2017

AbstractBackground: Perianal fistula is a commonly encountered condition in routine surgical practice. Accurate presurgical mapping of these tracts is vital to prevent recurrence. We have assessed the effectiveness of percutaneous instillation of aqueous jelly prior to magnetic resonance (MR) fistulography. Aims and Objectives: To study the role of percutaneous instillation of aqueous jelly in fistulous tracts prior to MR fistulography. Materials and Methods: All patients with active discharge, referred for MR fistulography between January 2014 and April 2016, were included in this study. Approximately 3–5 ml of sterile aqueous jelly was percutaneously instilled into the external openings prior to MR fistulography. Post MR fistulography, patients were monitored till surgery for pain, fever, or bleeding.The type of fistulae, location of internal openings, lateral ramifications, and presence of abscess were compared with per operative findings for diagnostic accuracy. Results: Sixty-four patients enrolled in our study had undergone preoperative MR fistulography with aqueous jelly instillation. MR fistulography revealed a total of 77 tracts and showed a sensitivity and specificity of 100% in delineation of type of tract. Forty-nine internal openings were identified with 94.2% sensitivity, 100% specificity, and 95.3% accuracy. 90.5% sensitivity, 100% specificity, and accuracy of 97% were observed in delineation of lateral ramifications. None of the patients reported pain, fever, or bleeding post procedure till surgery. Conclusion: Percutaneous instillation of aqueous jelly prior to MR fistulography is a safe, cost effective, and accurate technique to provide a comprehensive delineation of the complex anatomy of perianal fistulae.
Alteration in the number and integrity of white matter tracts in the preterm: A quantitative diffusion tensor imaging and diffusion fibre tractography in children
Authors: Sreedharan Ruma M , Aiyappan Subramonium , Roy N 
Published: July 2017

Abstract
Purpose: Periventricular white matter is most commonly injured in preterm babies with hypoxia. To assess white matter damage, we decided to perform diffusion tensor imaging (DTI) in preterm children with history of hypoxia and magnetic resonance imaging (MRI) features of periventricular leukomalacia (PVL) (PTH). We hypothesized that the PTH have reduced number of white matter fibres compared to age matched pre term children without hypoxia (PTHO), and also depending on the severity of PVL, there could be reduction in the number of fibres as well. Materials and Methods: The present study was carried out at the Government Medical College, Thiruvananthapuram. DTI was performed on 15 PTH and 15 PTHO. We measured number of fibres and fractional anisotropy of corpus callosum (CC) and optic radiations (OR). Results: There was significant difference between two groups with regard OR (P &lt; 0.001).The mean number of OR fibres in cases and control was 104 ± 28.44 (mean ± SD) and 578 ± 286 (mean ± SD), respectively.The mean number of CC in cases was 953 ± 429 and in controls was 1625 ± 116 with a P value &lt;0.56. No significant difference in FA was seen between cases and controls (P = 0.94). Conclusions: Preterm children with history of hypoxia and MRI features of PVL show reduced number of CC and OR compared to preterm children without hypoxia. There was significant correlation between PVL severity and number of OR fibres which could be due to the preferential involvement of periventricular white matter, in which OR has a major contribution.

Published: July 2017

ABSTRACT
This case report highlights the effective management of a maxillary lateral incisor with perio-endo lesion precipitated and complicated by the presence of a deep palatoradicular groove extending up to the root apex. Despite an apparently poor prognosis, the tooth was successfully managed by a collaborative endodontic and surgical periodontal therapy. The periodontal ligament attachment and periradicular healing were appreciated both clinically and radiographically at 3-month follow-up.

Single-visit Apexification using Biodentin
Authors: Anilkumar Aadit , Rajendran Ratheesh , Nazar Faisal 
Published: July 2017

ABSTRACT
Trauma to the tooth mainly results in pulpal injury, and these injuries during formative stage can result in incomplete root formation. This can result in failure in closure of root apex, resulting in wide open apex. This causes problem for the conventional root canal therapy as there is no apical stop against which the obturation material can be condensed. The management of a nonvital tooth with open apex is aimed at creation of an apical barrier. The newly introduced bioactive dentin substitute commercially available as biodentin is a promising material. It is a cement for stimulating hard tissue formation, i.e., the formation of reactive or reparative (tertiary) dentin. This case report describes the management of a traumatized permanent maxillary central incisor with an open apex.
