Published: October 2017

Magnetic molecularly imprinted polymers (MMIPs), combination of outstanding magnetism with specific selective binding capability for target molecules, have proven to be attractive in separation science and bio-applications. Herein, we proposed the core–shell magnetic molecularly imprinted polymers for food analysis, employing the Fe3O4 particles prepared by co-precipitation protocol as the magnetic core and MMIP film onto the silica layer as the recognition and adsorption of target analytes. The obtained MMIPs materials have been fully characterized by scanning electron microscope (SEM), Fourier transform infrared spectrometer (FT-IR), vibrating sample magnetometer (VSM), and re-binding experiments. Under the optimal conditions, the fabricated Fe3O4@MIPs demonstrated fast adsorption equilibrium, a highly improved imprinting capacity, and excellent specificity to target sterigmatocystin (ST), which have been successfully applied as highly efficient solid-phase extraction materials followed by high-performance liquid chromatography (HPLC) analysis. The MMIP-based solid phase extraction (SPE) method gave linear response in the range of 0.05–5.0 mg·L−1 with a detection limit of 9.1 µg·L−1. Finally, the proposed method was used for the selective isolation and enrichment of ST in food samples with recoveries in the range 80.6–88.7% and the relative standard deviation (RSD) <5.6%.

Published: October 2017

The tannery industry is renowned for the huge amount of toxic solid and liquid waste generated from the cleaning, fleshing, splitting, tanning, shaving and buffing of raw materials. Biomass briquettes are a proven way of generating energy from waste. This study investigates the development and characterization of biomass briquettes from tannery solid wastes (TSWs). TSWs, which comprise hair, flesh, chrome shavings and buffing dust, were collected from a tannery in Kano, Nigeria, to formulate and characterize six briquettes. Scanning electron microscopy and proximate analysis were carried out on the samples. The six briquettes, comprising varying ratios of hair, flesh, chrome shavings and buffing dust, were molded and characterized. Thermal efficiency, durability and compressive strength, among other properties, were determined for the six briquette formulations. The briquettes developed had calorific values between 18.632 and 24.101 MJ/kg. Durability of the briquettes ranged from 98.12% to 99.77%. The energy values were within the range of 17.462–24.101 MJ/kg, which was comparable to other fuel sources such as sub-bituminous coal (20.000–24.730 MJ/kg). This study shows that TSWs can be used for fuel briquette production, which is a source of sustainable energy generation. It is environmentally friendly, cost effective and affordable compared to fossil fuel.
Sharpening the VNIR and SWIR Bands of Sentinel-2A Imagery through Modified Selected and Synthesized Band Schemes
Authors: Park Honglyun , Choi Jaewan , Park Nyunghee , Choi Seokkeun
Published: October 2017

In this work, the bands of a Sentinel-2A image with spatial resolutions of 20 m and 60 m are sharpened to a spatial resolution of 10 m to obtain visible and near-infrared (VNIR) and shortwave infrared (SWIR) spectral bands with a spatial resolution of 10 m. In particular, we propose a two-step sharpening algorithm for Sentinel-2A imagery based on modified, selected, and synthesized band schemes using layer-stacked bands to sharpen Sentinel-2A images. The modified selected and synthesized band schemes proposed in this study extend the existing band schemes for sharpening Sentinel-2A images with spatial resolutions of 20 m and 60 m to improve the pan-sharpening accuracy by changing the combinations of bands used for multiple linear regression analysis through band-layer stacking. The proposed algorithms are applied to the pan-sharpening algorithm based on component substitution (CS) and a multiresolution analysis (MRA), and our results are then compared to the sharpening results when using sharpening algorithms based on existing band schemes. The experimental results show that the sharpening results from the proposed algorithm are improved in terms of the spatial and spectral properties when compared to existing methods. However, the results of the sharpening algorithm when applied to our modified band schemes show differing tendencies. With the modified, selected band scheme, the sharpening result when applying the CS-based algorithm is higher than the result when applying the MRA-based algorithm. However, the quality of the sharpening results when using the MRA-based algorithm with the modified synthesized band scheme is higher than that when using the CS-based algorithm.
An Objective Balance Error Scoring System for Sideline Concussion Evaluation Using Duplex Kinect Sensors
Authors: Zhu Mengqi , Huang Zhonghua , Ma Chao , Li Yinlin
Published: October 2017

Sports-related concussion is a common sports injury that might induce potential long-term consequences without early diagnosis and intervention in the field. However, there are few options of such sensor systems available. The aim of the study is to propose and validate an automated concussion administration and scoring approach, which is objective, affordable and capable of detecting all balance errors required by the balance error scoring system (BESS) protocol in the field condition. Our approach is first to capture human body skeleton positions using two Microsoft Kinect sensors in the proposed configuration and merge the data by a custom-made algorithm to remove the self-occlusion of limbs. The standing balance errors according to BESS protocol were further measured and accessed automatically by the proposed algorithm. Simultaneously, the BESS test was filmed for scoring by an experienced rater. Two results were compared using Pearson coefficient r, obtaining an excellent consistency (r = 0.93, p < 0.05). In addition, BESS test–retest was performed after seven days and compared using intraclass correlation coefficients (ICC), showing a good test–retest reliability (ICC = 0.81, p < 0.01). The proposed approach could be an alternative of objective tools to assess postural stability for sideline sports concussion diagnosis.

Published: October 2017

Energy storage systems (ESS) play an important role in the performance of mining vehicles. A hybrid ESS combining both batteries (BTs) and supercapacitors (SCs) is one of the most promising solutions. As a case study, this paper discusses the optimal hybrid ESS sizing and energy management strategy (EMS) of 14-ton underground load-haul-dump vehicles (LHDs). Three novel contributions are added to the relevant literature. First, a multi-objective optimization is formulated regarding energy consumption and the total cost of a hybrid ESS, which are the key factors of LHDs, and a battery capacity degradation model is used. During the process, dynamic programming (DP)-based EMS is employed to obtain the optimal energy consumption and hybrid ESS power profiles. Second, a 10-year life cycle cost model of a hybrid ESS for LHDs is established to calculate the total cost, including capital cost, operating cost, and replacement cost. According to the optimization results, three solutions chosen from the Pareto front are compared comprehensively, and the optimal one is selected. Finally, the optimal and battery-only options are compared quantitatively using the same objectives, and the hybrid ESS is found to be a more economical and efficient option.
Urban Foraging: A Ubiquitous Human Practice Overlooked by Urban Planners, Policy, and Research
Authors: Shackleton Charlie , Hurley Patrick , Dahlberg Annika , Emery Marla , Nagendra Harini
Published: October 2017

Although hardly noticed or formally recognised, urban foraging by humans probably occurs in all urban settings around the world. We draw from research in India, South Africa, Sweden, and the United States to demonstrate the ubiquity and varied nature of urban foraging in different contexts. Across these different contexts, we distil seven themes that characterise and thereby advance thinking about research and the understanding of urban foraging. We show that it is widespread and occurs across a variety of urban spaces and places. The species used and the local practices vary between contexts, and are in constant flux as urban ecological and social settings change. This requires that urban foragers are knowledgeable about diverse species, harvest locations, and rights of access, and that their practices are adaptable to changing contexts. Despite its ubiquity, most cities have some forms of regulations that prohibit or discourage urban foraging. We highlight a few important exceptions that can provide prototypes and lessons for other cities regarding supportive policy frameworks and initiatives. The formulation of dynamic policy, design, and management strategies in support of urban foraging will benefit from understanding the common characteristics of foraging in cities worldwide, but also will require comprehension of the specific and dynamic contexts in which they would be implemented.

Published: October 2017

Abstract: Artificial Floating Islands (AFIs) are human-made floating structures capable of supporting aquatic vegetation. Previous studies pointed out that most AFIs use aquatic plants to carry out improvement of water quality and ecological conservation. This study proposed a modified AFI system, named Green Water Farm (GWF), to increase the practical application value of traditional AFIs, and added a special design to create an environment that allows for terrestrial plants (including vegetables and flowers) to grow and to carry out improvement of water quality and ecological conservation. The research site was located at the waterfront of Li-tze Lake in Pitou Township, Taiwan. A GWF was established to evaluate the improvement of water quality and ecological conservation. During one year, water quality and ecological conservation assessments were recorded to investigate the performance of GWF system. The research results showed that GWF could improve water quality and ecological conservation. In addition, the results of this study can provide useful information for more food sources for humans and animals, and increase biodiversity and ecological conservation.

Published: October 2017

Forest certification is a voluntary verification tool that has been gaining importance within the global sustainability issues as an independent verification tool for sustainable forest management and wood processing industry and as an influencer in private and public purchasing policies and a component of emerging wood harvesting and trade legality schemes. This study focuses on the chain-of-custody (CoC) component of forest certification. A survey of CoC certified companies in the Czech Republic and Slovakia was carried out to explore the understanding of the concept and role of forest and CoC certification as an environmental, economic, and social tool. It aimed to determine expectations following from the implementation of CoC certification by companies and to identify difficulties in existing certified wood product supply chains and costs related to purchase and sales of certified forest products, respectively. Results indicate that respondents demonstrated a high level of understanding of the CoC concept and that they link forest certification mainly to the issues of legality, tracing the origin source of supply and promotion of sustainable utilisation of wood. The main expected benefits are linked to the improvement of an external company image followed by penetration of new markets and increase of sales volume. CoC is not considered a tool to improve internal company performance and efficiency. The key problems connected to certified supply chains relate to the sufficient quantity of certified forest products, low margins and overpriced certified material inputs. Respondents reported none or minimum price premiums for their certified products over non-certified alternatives. Several differences related to the understanding of the sustainable forest management concept and the level of price premium paid for certified inputs were identified between the PEFC (Programme for the Endorsement of Forest Certification) and FSC (Forest Stewardship Council) certified companies as well as between the different forest products sectors.

Published: October 2017

Abstract: The Naval Maintenance and Repair Command Acquisition Management Unit (NMRC-AMU) of the Taiwan Navy suffered from poor stock control of spare parts and inadequate modification of requested items and manufacturer/part codes during recent years. Therefore, the purpose of this study is to investigate core categorization, coordination, and procurement (CCP) problems, to formulate feasible solutions and then to improve the CCP performances of spare parts in NMRC-AMU. The Teoriya Resheniya Izobreatatelskih Zadatch (TRIZ) method was applied to solve this issue. A problem hierarchy analysis (PHA) was first used to identify the core problems. Then, the 40 principles were used to determine the ideal improvement solution and formulate a solution strategy that simultaneously simplified CCP processed and enhanced the correctness of procurement tasks, thereby elevating CCP efficiency, supporting the Taiwan Navy repair missions, and satisfying fleet maintenance and servicing demands. The results indicated that total 6925 requests for coordination and procurement were submitted. Of these requests, 4366 requests had been completed (with total 102 cases), and the CCP efficiency is 63.0%. After improvement by this study, a total of 4529 items were submitted and 3592 executed items were completed (with a total of 172 cases), and the CCP efficiency is 79.3%. The improvement percentage of the CCP efficiency and completed cases are 30.6% and 68.6%, respectively. The performances are good and the TRIZ could be applied for other military forces.
Genomewide variation provides insight into evolutionary relationships in a monkeyflower species complex (Mimulus sect. Diplacus)
Authors: Chase Madeline A. , Stankowski Sean , Streisfeld Matthew A.
Published: October 2017

PREMISE OF THE STUDY:

Evolutionary radiations provide excellent opportunities to study the origins of biodiversity, but rapid divergence and ongoing gene flow make inferring evolutionary relationships among taxa difficult. Consequently, combining morphological and genomic analyses will be necessary to clarify the evolutionary history of radiations. We used an integrative approach to shed light on relationships within a diverse radiation of monkeyflowers (Mimulus section Diplacus) with a controversial taxonomic history.

METHODS:

We used genomewide single nucleotide polymorphism data and a combination of phylogenetic and population genomic analyses to infer the evolutionary relationships within the group. Tests for hybridization were performed to reveal sources of shared variation, and multivariate analyses of floral trait data were conducted to examine the correspondence between phenotypic and phylogenetic data.

KEY RESULTS:

We identified four primary clades with evidence for some shared variation among them. We also detected evidence for recent gene flow between closely related subclades and populations. Strong discordance between floral trait and molecular data provides evidence for divergent and convergent phenotypic evolution.

CONCLUSIONS:

Mimulus section Diplacus has all the hallmarks of a rapid radiation, including diverse taxa that are at different stages of divergence, extensive shared variation among taxa, and complex patterns of phenotypic evolution. Our findings will direct future evolutionary research and have important taxonomic implications that highlight the need for a new revision of section Diplacus.
The evolution and diversification of the red oaks of the California Floristic Province (Quercus section Lobatae, series Agrifoliae)
Authors: Hauser Duncan A. , Keuter Al , McVay John D. , Hipp Andrew L. , Manos Paul S.
Published: October 2017

PREMISE OF THE STUDY:

The California Floristic Province (CA‐FP) is a unique and diverse region of floral endemism, yet the timing and nature of divergence and diversification of many lineages remain underexplored. We seek to elucidate the evolutionary history of the red oaks of the CA‐FP, the Agrifoliae.

METHODS:

We collected PstI‐associated RAD‐seq data as well as morphometrics from individuals of the four species across their ranges, including varieties and hybrids. Phylogeny and divergence times were estimated. We analyzed morphological differentiation in over 70 plants using PCA and assessed species delimitation and admixture using genotype clustering analysis in over 40 plants.

KEY RESULTS:

We find that the Agrifoliae are monophyletic and sister to all other red oak species. Within the Agrifoliae, all species are supported, with Quercus kelloggii sister to a clade of subevergreen taxa: (Quercus agrifolia – (Q. parvula + Q. wislizeni)). Molecular and morphometric analyses are equivocal for named varieties. Notably, Q. parvula var. tamalpaisensis appears to be part of a hybrid swarm between Q. parvula and Q. wislizeni. Dating estimates were concordant with previous hypotheses and geological evidence, with diversification occurring between 10 and 20 million years ago.

CONCLUSIONS:

The Agrifoliae represent a geographically discrete, early‐diverging red oak lineage that diversified during the period of drying and warming associated with Sierran uplift during the middle Miocene. Molecular differentiation within the clade supports the current taxonomy, including an east–west species level pattern (Q. parvula and Q. wislizeni) and north–south intraspecific patterns to some degree, although the latter require additional study.

Published: October 2017

A direct consequence of hierarchical galaxy formation is the existence of dual supermassive black holes, which may be preferentially triggered as active galactic nuclei (AGNs) during galaxy mergers. Despite decades of searching, however, dual AGNs are extremely rare, and most have been discovered serendipitously. Using the all-sky WISE survey, we identified a population of over 100 morphologically identified interacting galaxies or mergers that display red mid-infrared colors often associated in extragalactic sources with powerful AGNs. The vast majority of these advanced mergers are optically classified as star-forming galaxies, which suggests that they may represent an obscured population of AGNs that cannot be found through optical studies. In this work, we present Chandra/ACIS observations and near-infrared spectra with the Large Binocular Telescope of six advanced mergers with projected pair separations less than ∼10 kpc. The combined X-ray, near-infrared, and mid-infrared properties of these mergers provide confirmation that four out of the six mergers host at least one AGN, with four of the mergers possibly hosting dual AGNs with projected separations less than ∼10 kpc, despite showing no firm evidence for AGNs based on optical spectroscopic studies. Our results demonstrate that (1) optical studies miss a significant fraction of single and dual AGNs in advanced mergers, and (2) mid-infrared pre-selection is extremely effective in identifying dual AGN candidates in late-stage mergers. Our multi-wavelength observations suggest that the buried AGNs in these mergers are highly absorbed, with intrinsic column densities in excess of

cm−2, consistent with hydrodynamic simulations.

Astrophysical polarization measurements in the soft gamma-ray band are becoming more feasible as detectors with high position and energy resolution are deployed. Previous work has shown that the minimum detectable polarization (MDP) of an ideal Compton polarimeter can be improved by ∼21% when an unbinned, maximum likelihood method (MLM) is used instead of the standard approach of fitting a sinusoid to a histogram of azimuthal scattering angles. Here we outline a procedure for implementing this maximum likelihood approach for real, nonideal polarimeters. As an example, we use the recent observation of GRB 160530A with the Compton Spectrometer and Imager. We find that the MDP for this observation is reduced by 20% when the MLM is used instead of the standard method.

-values coming from 15 odd-parity energy levels are provided, 22 of which have not been reported previously and 63 of which have values with lower uncertainty than the existing data. The radiative lifetimes for 60 upper energy levels are presented, 39 of which have no previous measurements.
The Formation and Physical Origin of Highly Ionized Cooling Gas
Authors: Bordoloi Rongmon , Wagner Alexander Y. , Heckman Timothy M. , Norman Colin A.
Published: October 2017

We present a simple model that explains the origin of warm, diffuse gas seen primarily as highly ionized absorption-line systems in the spectra of background sources. We predict the observed column densities of several highly ionized transitions such as O vi, O vii, Ne viii, N v, and Mg x, and we present a unified comparison of the model predictions with absorption lines seen in the Milky Way disk, Milky Way halo, starburst galaxies, the circumgalactic medium, and the intergalactic medium at low and high redshifts. We show that diffuse gas seen in such diverse environments can be simultaneously explained by a simple model of radiatively cooling gas. We show that most such absorption-line systems are consistent with being collisionally ionized, and we estimate the maximum-likelihood temperature of the gas in each observation. This model satisfactorily explains why O vi is regularly observed around star-forming low-z L* galaxies, and why N v is rarely seen around the same galaxies. We further present some consequences of this model in quantifying the dynamics of the cooling gas around galaxies and predict the shock velocities associated with such flows. A unique strength of this model is that while it has only one free (but physically well-constrained) parameter, it nevertheless successfully reproduces the available data on O vi absorbers in the interstellar, circumgalactic, intragroup, and intergalactic media, as well as the available data on other absorption lines from highly ionized species.

We report an improved measurement of the cosmic microwave background B-mode polarization power spectrum with the Polarbear experiment at 150 GHz. By adding new data collected during the second season of observations (2013–2014) to re-analyzed data from the first season (2012–2013), we have reduced twofold the band-power uncertainties. The band powers are reported over angular multipoles

, where the dominant B-mode signal is expected to be due to the gravitational lensing of E-modes. We reject the null hypothesis of no B-mode polarization at a confidence of 3.1σ including both statistical and systematic uncertainties. We test the consistency of the measured B-modes with the Λ Cold Dark Matter (ΛCDM) framework by fitting for a single lensing amplitude parameter A

Stellar Flares Observed in Long-cadence Data from the Kepler Mission
Authors: Doorsselaere Tom Van , Shariati Hoda , Debosscher Jonas
Published: October 2017

We aim to perform a statistical study of stellar flares observed by Kepler. We want to study the flare amplitude, duration, energy, and occurrence rates, and how they are related to the spectral type and rotation period. To that end, we have developed an automated flare detection and characterization algorithm. We have harvested the stellar parameters from the Kepler input catalog and the rotation periods from McQuillan et al. We find several new candidate A stars showing flaring activity. Moreover, we find 653 giants with flares. From the statistical distribution of flare properties, we find that the flare amplitude distribution has a similar behavior between F+G types and K+M types. The flare duration and flare energy seem to be grouped between G+K+M types versus F types and giants. We also detect a tail of stars with high flare occurrence rates across all spectral types (but most prominent in the late spectral types), and this is compatible with the existence of “flare stars.” Finally, we have found a strong correlation of the flare occurrence rate and the flare amplitude with the stellar rotation period: a quickly rotating star is more likely to flare often and has a higher chance of generating large flares.
La transmission troublée, l’exemple de l’adoption
Authors: Le Run Jean-Louis
Published: October 2017

Prenant l’exemple de l’adoption, l’auteur interroge d’abord le désir de transmettre en chacun d’entre nous. Donner la vie, avoir un enfant est la transmission la plus évidente. À travers l’enfant prolongement narcissique des parents, il s’agit de donner un sens à sa vie, face à la conscience de sa finitude, de se perpétuer, mais aussi du désir de partager à travers l’éducation de l’enfant. Mais ce puissant désir de transmettre se trouve souvent contrarié, d’une part parce que ce n’est pas toujours ce que nous voulons qui passe d’une génération à l’autre, mais aussi, sur le mode transgénérationnel, des fantômes, du négatif, des secrets. Ensuite parce que la transmission étant fondamentalement intersubjective, sa réussite dépend de l’acceptation par celui qui en est l’objet. Enfin parce qu’elle se trouve parfois empêchée, par exemple lorsqu’une stérilité ou une configuration de la famille ne permet pas d’avoir d’enfant, ou troublée. L’adoption s’offre alors comme possibilité de résoudre cette impasse et de rembourser la dette de vie reçue de ses parents à la naissance, dans la perspective maussienne du donner-recevoir-rendre qui organise la transmission, mais, de façon paradoxale, elle met aussi en jeu les difficultés susmentionnées. Surgissent alors les obstacles spécifiques de l’adoption : rupture initiale de la transmission, héritage plus ou moins lourd d’une histoire qui s’est construite ailleurs mais que les parents devront accepter et transmettre malgré tout. Les fantasmes de transmission sont le fruit du travail psychique qui accompagne la « digestion » de cet héritage du côté de l’enfant comme de ses parents. Le travail thérapeutique d’accompagnement dans l’élaboration de l’héritage gagne à prendre en compte la perspective générationnelle.

Nous relatons l’histoire de Louise, une petite fille différente rencontrée en consultation et pour qui les questions de transmission, sous toutes ses formes, sont au coeur de son histoire : entre transmission et détermination (avec la question de l’inné et de l’acquis), transmission et prédiction (et de certains enjeux du diagnostic prénatal), transmission et prédestination (avec la question du diagnostic précoce), transmission et information au patient ou sa famille (sous-couvert de la loi de 2002), transmission et narration (dans la rencontre avec l’enfant). Dans ces débats, le pédopsychiatre de liaison en maternité et en service de pédiatrie a une place fondamentale, en tant que praticien de l’inattendu et artisan de la rencontre avec l’enfant et ses parents.

Published: October 2017

Dans cet article nous nous intéressons à la relation entre une mère et sa fille, aujourd’hui âgée de 10 ans, suivie depuis sa naissance pour une malformation sévère de la jambe au Centre de référence des maladies rares des malformations des membres. Cette pathologie a des conséquences sur l’autonomie et la qualité de vie du sujet sans néanmoins toucher la sphère du vital ni du guérissable. Sa prise en charge chirurgicale, à savoir l’amputation du pied malformé, afin d’optimiser l’appareillage et favoriser une marche physiologique, fait l’objet d’une décision parentale complexe aux effets irréversibles concernant le corps de l’enfant. Notre questionnement clinico-théorique porte sur les enjeux psychiques et interculturels suscités par cette décision impliquant plusieurs acteurs : enfant, famille, équipe pluriprofessionnelle de soins. Une réflexion sur le rôle du psychologue dans cette dynamique sera également menée.
Chapitre 2. Precautionary principle and civil law
Authors: Byk Christian
Published: October 2017

Le principe de précaution trouve son origine dans le droit international mais il a rapidement investi le droit national et élargi son champ d’application de l’environnement aux problèmes de santé, comme le montre la crise de la santé qui s’est produite en France depuis les années 80. Quelle place fait-il au droit civil ? La réalité d’un certain « dialogue » entre principe de précaution et droit civil est un déni pour ceux qui y ont vu le mariage de l’eau et du feu car, de fait, le droit civil utilise le concept de précaution en tenant compte de la question de la responsabilité parce que la précaution est devenue un élément d’évaluation des conditions de responsabilité et de ses effets.

Éthique des frontières et justice des communs
Authors: Renouard Cécile
Published: October 2017

La thèse défendue est celle d’un besoin renforcé d’État-patrie au service des communs locaux et mondiaux. Dans un premier temps, les frontières sont envisagées comme des espaces, des dynamiques de partage pour un monde commun, ce qui implique de revisiter les compréhensions des critères de justice à l’intérieur d’une société politique fermée, pour les ouvrir en permanence vers les marges, pour permettre à chacun de se sentir chez soi dans notre demeure commune. Une telle perspective invite à penser, dans un deuxième temps, les frontières au sens des engagements en commun, enracinés dans des limites/bornes (notamment territoriales) ; il s’agit bien de retrouver le sens du lien à une terre, à une patrie, par une réappropriation collective, citoyenne, des frontières en tant que garde-fous du bien commun.

Published: October 2017

Southwest China has a high burden of spinal tuberculosis (TB). Few large case studies of spinal TB in southwest China have been conducted. This study investigated the features of 921 patients who were treated for spinal TB at a general hospital in southwest China between 2001 and 2016. Demographic data, clinical data, laboratory data, imaging findings, treatment methods, and outcomes of patients who were admitted to the hospital for spinal TB were reviewed retrospectively. The annual incidence of spinal TB increased throughout the study period. The greatest number of patients were 41 to 50 years old (22.04%). Local pain was the most common symptom (97.8%). A significant difference in the duration of symptoms was observed between rural populations (28.40 months) and urban populations (10.17 months) (
P
=.041). Of the patients, 32.68% had a normal erythrocyte sedimentation rate and 25.84% had a normal C-reactive protein level. The lumbar spine was the most commonly involved spinal site (44.77%), followed by the thoracic spine (43.60%). All of the patients underwent chemotherapy, and 77.10% of patients underwent surgery. Most of the patients were cured, with the exception of 2.19% of patients who discontinued chemotherapy after early improvement of clinical status. Spinal TB is still a major public health problem in southwest China. Chemotherapy and surgery can yield satisfactory outcomes with timely diagnosis and long-term treatment. It is urgent to increase the attention paid to spinal TB and improve knowledge of this disease among the general public, especially in southwest China. [

Published: October 2017

Skeletal tibial traction is a temporizing measure used preoperatively for femoral fractures to improve the length and alignment of the limb and provide pain relief. The goal of this study was to identify possible neurovascular morbidity associated with the use of bedside skeletal tibial traction to treat femur fractures. All femoral fractures treated with proximal tibial traction during a 10-year period at an urban level I trauma center were retrospectively reviewed. The medical record was reviewed to determine whether a pin-related complication had occurred. Records also were reviewed to identify ipsilateral multi-ligamentous knee injuries that were not diagnosed until after the application of traction. In total, 303 proximal tibial traction pins were placed. A total of 7 (2.3%; 95% confidence interval, 0.60%–4.0%) pin-related neurologic complications and zero vascular complications were noted. All complications involved motor and/or sensory deficits in the distribution of the peroneal nerve. Of the 7 complications, 6 resolved fully after surgery and removal of the pin. After traction placement, 6 (2.0%) ipsilateral multiligamentous knee injuries were diagnosed. None of these patients had a neurovascular complication. This study suggests that bedside placement of proximal tibial traction for femoral fractures is associated with a low incidence of neurovascular complications and that traction can be safely placed at the bedside by residents. A thorough neurovascular examination should be performed before insertion, and care should be taken to identify the proper starting point and reduce soft tissue trauma during pin placement. [

Portraits d'enseignants de FLS, pédagogues de l'hybride. Vers une ébauche de modèle
Authors: Hamel Marie-Josée
Published: October 2017

Cet article porte sur une initiative d'hybridation de cours de langues au sein d'une institution universitaire canadienne. S'appuyant sur une démarche d'ingénierie ergonomique pour mettre en œuvre le processus de conception des cours hybrides, cette initiative a donné lieu à une recherche-action-développement qui a mobilisé un ensemble d'acteurs, dont trois enseignants de FLS que nous avons suivis. À travers les portraits de ces enseignants, nous proposons une analyse des dimensions contextuelles, pédagogiques et de l'idéal professionnel de leurs représentations professionnelles en tant que pédagogues de l'hybride. Ces portraits ont été construits sur la base d'une analyse qualitative d'un questionnaire distribué en amont de l'initiative hybride et d'un entretien semi-guidé mené après celle-ci. Ils ont conduit à l'ébauche d'un modèle à visée formative de la dimension pédagogique de l'enseignement d'une langue en modalité hybride.

The paper reviews certain integral equation approaches and related numerical methods used in studies of biomedical applications of electromagnetic fields pertaining to transcranial magnetic stimulation (TMS) and nerve fiber stimulation. TMS is analyzed by solving the set of coupled surface integral equations (SIEs), while the numerical solution of governing equations is carried out via Method of Moments (MoM) scheme. A myelinated nerve fiber, stimulated by a current source, is represented by a straight thin wire antenna. The model is based on the corresponding homogeneous Pocklington integro-differential equation solved by means of the Galerkin Bubnov Indirect Boundary Element Method (GB-IBEM). Some illustrative numerical results for the TMS induced fields and intracellular current distribution along the myelinated nerve fiber (active and passive), respectively, are presented in the paper.
Paraneoplastic Edematous Dermatomyositis: A Rare Syndrome Observed in a Case of Small Cell Lung Cancer

Published: October 2017

Dermatomyositis with subcutaneous edema is a rare process with few reported cases. We report a 63-year-old with lung cancer who presented with an erythematous skin rash and was found to have biopsyproven dermatomyositis. Her course was complicated by generalized edema, myalgias, muscle weakness, dysphagia, and laryngeal edema. The edema was severe and caused respiratory distress requiring intubation. The patient underwent therapy with high-dose glucocorticoids and intravenous immunoglobulin but failed treatment. Altogether, she presented as an extreme case and rare variant of dermatomyositis, known as edematous dermatomyositis. Diagnostic and treatment guidelines do not account for this variant and literature pertaining to edematous dermatomyositis is sparse. Moreover, this disease was a paraneoplastic manifestation of her small cell lung cancer, which is rarely observed. There are no cases reporting edematous dermatomyositis as a paraneoplastic manifestation of small cell lung cancer, and we highlight the high rate of morbidity and mortality in such patients.
Efficacy of the inside-out tramsobturator tension-free vaginal tape (TVT-ABBREVO) for the treatment of stress urinary incontinence after a 12-month follow-up
Authors: Rappa Carlo , Saccone Gabriele
Published: October 2017

The aim of this study was to evaluate the efficacy of the inside-out tension-free vaginal tape transobturator approach or TVT-Obturator system (TVT-ABBREVO) in women with stress urinary incontinence (SUI). This is a prospective single arm study of women with SUI who underwent a TVT-ABBREVO procedure. The inclusion criterion was a diagnosis of SUI urodynamically proven without detrusor over activity. SUI was defined as involuntary urine leakage with stress in the absence of detrusor over activity with or without intrinsic sphincter deficiency. Before, and 12 months after surgery women received urodynamic test, pelvic examination, and a personal interview using the Urogenital Distress Inventory (UDI) and the Incontinence Impact Questionnaire (IIQ). The primary outcome was the incidence of incontinency through cough stress test during the urodynamic exam. A total of 90 women were included in the analysis. Our analysis showed that the incidence of incontinence through cough stress test during the urodynamic exam was significantly less 12 months after the intervention (100% vs 3%; P-value =0.001). Moreover, we found a significantly improvement of the quality of life measured by UDI score (13±4.5 vs 7.3±2.2 points; P-value 0.01) and IIQ score (14±5.7 vs 8.1 vs 3.1 points; P-value 0.02). No intraoperative complications were noticed. TVT-ABBREVO significantly reduced the incidence of stress urinary incontinence. In the authors’ experience, this technique resulted technically simple and provided high objective and subjective long-term efficacy, a clinically meaningful improvement in patient quality of life, and an excellent safety profile.

Published: October 2017

Urinary incontinence (UI) is a significant health problem leading to physical, psychological and social discomfort, especially in elderly women. A study of prevalence and classification of UI in the Roraima state was taken up to aid in formulation of healthcare policy and improvement of patient referral facilities. A retrospective study of 765 female patients who have undergone urodynamic examination between November 2013 and December 2014 has been conducted. Subjects were classified in to diagnostic classes: normal, stress incontinence, mixed incontinence, sensitive emergency, overactive bladder, and others. The overall prevalence of UI was 58.4%. The highest prevalence was observed in the menopausal age group (45- 49 years). Among the etiologies of UI, stress incontinence ranked highest at 30.9%, followed by overactive bladder at 6.9%. In the 25-55 years age group, stress incontinence was predominant (50-63%), while overactive bladder became significant (14-44%) in later years. The prevalence of UI in women in the state of Roraima, was high, in line with its prevalence in Brazil, as well as other western countries.
Observational study comparing pharmacoinvasive strategy with primary percutaneous coronary intervention in patients presenting with ST elevation myocardial infarction to a tertiary care centre in India
Authors: Alex AG , Lahiri A , Devika  , Geevar T , George OK
Published: October 2017

Objective:

The objective was to study whether the incidence of composite end points (mortality, cardiogenic shock and re-myocardial infarction [re-MI]) in pharmacoinvasive strategy was noninferior to primary percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI).

Methods:

This was an observational study which included 138 patients. The study included patients admitted with a diagnosis of STEMI within 24 h of symptom onset, who underwent primary PCI or pharmacoinvasive therapy in a single center over a 9-month period. Primary end points (death within 30 days, re-MI within 30 days, and cardiogenic shock) and secondary end points (arrhythmias, bleeding manifestations, ischemic stroke, ejection fraction, mechanical complications, and duration of hospital stay) were compared between the two groups at 1 month after intervention.

Results:

At one month follow-up, the incidence rate for primary end points was 5 events per 43 patients (11.6%) in pharmacoinvasive arm and 18 events per 95 patients (18.9%) in primary PCI arm, a difference of - 7.3% (95% confidence interval: 18.5, 7.1). This finding shows that pharmacoinvasive strategy as compared with primary PCI in the management of STEMI was equivalent in terms of composite primary outcome. There was no significant difference between the secondary outcomes between the two groups. Use of thrombus aspiration device and in turn the thrombus burden was significantly lower in the pharmacoinvasive arm.

Conclusion:

This observational study showed that pharmacoinvasive strategy was as good as primary PCI in STEMI, in our setting, where primary PCI may be delayed or not possible at all due to financial and logistic constraints.
Multi-organ IgG4-related disease
Authors: Bhardwaj S , Goyal S , Yadav AK , Goyal A
Published: October 2017

IgG4-related disease (IgG4-RD) is a multisystemic mass forming immune-mediated disease entity, commonly creating confusion and diagnostic challenges. We present a case of a 25-year-old female who presented with bilateral orbital masses, lymphadenopathy, paraspinal and renal masses, which clinicoradiologically simulated lymphoma. The lymph node biopsy revealed interfollicular sheets of plasma cells creating confusion with Castleman's disease and marginal zone lymphoma. The orbital biopsy revealed ductular destruction, periductular plasma cells, and fibrosis, mimicking Sjogren's syndrome and Castleman's disease. However, the correlation of the clinical features with histopathological findings, IgG4 immunopositivity, and serum studies helped in clinching the diagnosis. This case presents an uncommon combination of clinical features infrequently reported in literature. Furthermore, and more importantly, it highlights the need to keep a differential of IgG4-RD in mind, to aid early and correct treatment of the disease.
