Published: March 2015

Abstract
The new intermetallic compound Sc5Co2In4 was synthesized by arc melting of the pure metals. Its crystal structure was investigated from single-crystal X-ray data: Pbam, a = 17.3400(7), b = 7.5940(5), c = 3.3128(2) Å, R1 = 0.0337, wR2 = 0.0620 for 1502 independent reflections with [I >2 σ(I)]. It is the first representative of the Lu5Ni2In4 type with cobalt.
Symptomatic empty sella syndrome: an unusual manifestation of Erdheim–Chester disease
Authors: Loh Wann Jia , Sittampalam Kesavan , Tan Suan Cheng , Chandran Manju 
Published: March 2015

Summary
Erdheim–Chester disease (ECD) is a potentially fatal condition characterized by infiltration of multiple organs by non-Langerhans histiocytes. Although endocrine dysfunction has been reported in association with ECD, to date, there have been no previous reports of empty sella syndrome (ESS) associated with it. We report the case of a patient with ECD who had symptomatic ESS. A 55-year-old man of Chinese ethnicity initially presented with symptoms of heart failure, fatigue and knee joint pain. Physical examination revealed xanthelasma, gynaecomastia, lung crepitations, hepatomegaly and diminished testicular volumes. He had laboratory evidence of hypogonadotrophic hypogonadism, secondary hypoadrenalism and GH deficiency. Imaging studies showed diffuse osteosclerosis of the long bones on X-ray, a mass in the right atrium and thickening of the pleura and of the thoracic aorta on fusion positron emission tomography–computed tomography. Magnetic resonance imaging (MRI) of the brain showed an empty sella. The diagnosis of ECD was confirmed by bone biopsy.

Learning points

ECD is a multisystemic disease that can affect the pituitary and other organs. The diagnosis of ECD is based on clinical and radiological features and histology, showing lipid-laden CD68+ CD1a− S100− histiocytes surrounded by fibrosis.

The finding of xanthelasmas especially in the presence of normal lipid levels in the presence of a multisystem infiltrative disorder should raise the suspicion of ECD.

Systemic perturbation of autoimmunity may play a role in the pathogenesis of ECD and is an area that merits further research.

BACKGROUND AND OBJECTIVES:
Pediatric encephalitis has a wide range of etiologies, clinical presentations, and outcomes. This study seeks to classify and characterize infectious, immune-mediated/autoantibody-associated and unknown forms of encephalitis, including relative frequencies, clinical and radiologic phenotypes, and long-term outcome.

METHODS:
By using consensus definitions and a retrospective single-center cohort of 164 Australian children, we performed clinical and radiologic phenotyping blinded to etiology and outcomes, and we tested archived acute sera for autoantibodies to N-methyl-D-aspartate receptor, voltage-gated potassium channel complex, and other neuronal antigens. Through telephone interviews, we defined outcomes by using the Liverpool Outcome Score (for encephalitis).

RESULTS:
An infectious encephalitis occurred in 30%, infection-associated encephalopathy in 8%, immune-mediated/autoantibody-associated encephalitis in 34%, and unknown encephalitis in 28%. In descending order of frequency, the larger subgroups were acute disseminated encephalomyelitis (21%), enterovirus (12%), Mycoplasma pneumoniae (7%), N-methyl-D-aspartate receptor antibody (6%), herpes simplex virus (5%), and voltage-gated potassium channel complex antibody (4%). Movement disorders, psychiatric symptoms, agitation, speech dysfunction, cerebrospinal fluid oligoclonal bands, MRI limbic encephalitis, and clinical relapse were more common in patients with autoantibodies. An abnormal outcome occurred in 49% of patients after a median follow-up of 5.8 years. Herpes simplex virus and unknown forms had the worst outcomes. According to our multivariate analysis, an abnormal outcome was more common in patients with status epilepticus, magnetic resonance diffusion restriction, and ICU admission.

CONCLUSIONS:
We have defined clinical and radiologic phenotypes of infectious and immune-mediated/autoantibody-associated encephalitis. In this resource-rich cohort, immune-mediated/autoantibody-associated etiologies are common, and the recognition and treatment of these entities should be a clinical priority.
Collaborative Care for Children With ADHD Symptoms: A Randomized Comparative Effectiveness Trial
Authors: Silverstein Michael , Hironaka L. Kari , Walter Heather J. , Feinberg Emily , Sandler Jenna , Pellicer Michelle , Chen Ning , Cabral Howard 
Published: March 2015

OBJECTIVES:
Although many attention-deficit/hyperactivity disorder (ADHD) care models have been studied, few have demonstrated individual-level symptom improvement. We sought to test whether complementing basic collaborative care with interventions that address common reasons for symptom persistence improves outcomes for children with inattention and hyperactivity/impulsivity.

METHODS:
We conducted a randomized comparative effectiveness trial of 2 care management systems for 6- to 12-year-old children being evaluated for ADHD (n = 156). All participants received care management with decision support. Care managers in the enhanced care arm also were trained in motivational and parent management techniques to help parents engage in their child’s treatment, address their own mental health needs, and manage challenging child behaviors. We used multivariable models to assess inattention, hyperactivity/impulsivity, oppositionality, and social skills over 1 year.

RESULTS:
Both treatment arms generated guideline concordant diagnostic processes in 94% of cases; 40% of children had presentations consistent with ADHD. For the entire sample, there were no differences in symptom trajectories between study arms; mean differences in change scores at 12 months were –0.14 (95% confidence interval –0.34 to 0.07) for inattention; –0.13 (–0.31 to 0.05) for hyperactivity/impulsivity; –0.09 (–0.28 to 0.11) for oppositionality; and 3.30 (–1.23 to 7.82) for social skills. Among children with ADHD-consistent presentations, enhanced arm participants experienced superior change scores for hyperactivity/impulsivity of –0.36 (–0.69 to –0.03), oppositionality –0.40 (–0.75 to –0.05), and social skills 9.57 (1.85 to 17.28).

CONCLUSIONS:
Among children with ADHD-consistent presentations, addressing barriers to engagement with care and challenging child behaviors has potential to improve the effectiveness of collaborative care.
Land transactions and violent conflict, a review of the cases of Turbo, Antioquia and El Carmen de Bolívar, Bolívar
Authors: García Reyes Paola , Vargas Reina Jenniffer 
Published: March 2015

This paper offers an analysis of the links between war, land markets and dispossession based on two case studies: the municipality of Turbo, Antioquia and El Carmen de Bolívar, Bolivar. To this end, firstly, the phenomenon of active paramilitary dispossession is placed in the framework of the general discussion on land grab. Then the general dynamics of the conflict, abandonment and land dispossession in both municipalities is described. Afterwards a broad typology is proposed on land transactions,1 including abandonment and asymmetrical and symmetrical transactions, based on the observed cases. Then the sequences, actors and associated mechanisms are defined for each case. Lastly, we conclude that even though dispossession did not occur in an institutional vacuum, in the cases studied the use of force as a form of appropriation is the result of specific conditions that are closer to the Hobbesian state of nature, where the armed actor can use and make the rules, whereas the transactions that arise from advantages in asymmetries of power and information are closer to market situations in which the appropriating actor uses the rules, but does not make them.
Critical undrained shear strength of sand-silt mixtures under monotonic loading
Authors: Bensoula Mohamed , Missoum Hanifi , Bendani Karim 
Published: March 2015

<p>This study uses experimental triaxial tests with monotonic loading to develop empirical relationships to estimate undrained critical shear strength. The effect of the fines content on undrained shear strength is analyzed for different density states. The parametric analysis indicates that, based on the soil void ratio and fine content properties, the undrained critical shear strength first increases and then decreases as the proportion of fines increases, which demonstrates the influence of fine content on a soil’s vulnerability to liquefaction. A series of monotonic undrained triaxial tests were performed on reconstituted saturated sand-silt mixtures. Beyond 30% fines content, a fraction of the silt participates in the soil’s skeleton chain force. In this context, the concept of the equivalent intergranular void ratio may be an appropriate parameter to express the critical shear strength of the studied soil. This parameter is able to control the undrained shear strength of non-plastic silt and sand mixtures with different densities.</p><p> </p><p><strong>Resumen</strong></p><p>Este estudio utiliza evaluaciones experimentales triaxiales con cargas repetitivas para desarrollar relaciones empíricas y estimar la tensión crítica de corte bajo condiciones no drenadas. El efecto de contenido de finos en la tensión de corte sin drenar se analizó en diferentes estados de densidad. El análisis paramétrico indica que, basado en la porosidad del suelo y las propiedades del material de finos, la tensión de corte sin drenar primero se incrementa y luego decrece mientras la proporción de finos aumenta, lo que demuestra la influencia de contenido de finos en la vulnerabilidad del suelo a la licuación. Una serie de las evaluaciones se realizó en mezclas rehidratadas y saturadas de arena y cieno. Más allá del 30 % de los contenidos finos, una fracción del cieno hace parte principal de la cadena de fuerza del suelo. En este contexto, el concepto de porosidad equivalente intergranular puede ser un parámetro apropiado para expresar la tensión crítica de corte del suelo estudiado. Este parámetro nos permite controlar la tensión de corte sin drenar de cieno no plástico y mezclas de arena de densidades diferentes.</p>
Study of the mineralization potential of the intrusives around Valis (Tarom-Iran)
Authors: Bahajroy Mojtaba , Taki Saeed 
Published: March 2015

<p>The study area is located in northwestern Iran in the central Iran zone, specifically the western Alborz sub-zone south of the Tarom-Hashtjin metallogenic zone. The exposed rock units in this area generally include Eocene volcanic rocks (lava flows and pyroclasts belonging to the Karaj formation) and Oligocene granitoid intrusive bodies. The intrusive bodies in the area have a petrographic composition of granite, syenite and monzonite and are mostly metaluminous. The dual characteristics of these intrusives (for example, the behavior of elements such as Rb, P, Ga/Al, Y/Nb, K/Na, and FeO/Fe2O3, the Rb/Nb ratios, the A/CNK molar ratios and the ACF and A/CNK-Fe2O3+FeO diagrams), some of which are consistent with the I nature and others with the S and A natures, show that the rocks are among hybrid granitoids and, in terms of the tectonic setting, lie within the WPG range. According to the Rb/Sr, Zr/Hf, K/Rb ratios, the granite melts that form the aforementioned bodies are not extremely evolved and have not undergone post magmatic activity, which would lead to mineralization. The Sm/Eu and Rb/Ba ratios and the behavior of Rb, Ba and Sr within the aforementioned granitoids show that the rocks are similar to average granitoids unrelated to Li, Be, Sn, W and Ta deposits; they fall within the range of barren granitoids but are partially fertile in Cu.</p><p> </p><p><strong>Resumen</strong></p><p>El área de este estudio está localizada en el noroeste de la zona central de Irán, específicamente en el oeste de la subzona de Alborz y al sur de la zona metalogénica de Tarom-Hashtjin.

Los cuerpos intrusivos en el área tienen una composición petrográfica de granito, sienita y monzonita mayormente metaluminosa. Las características duales de estas intrusiones (por ejemplo, el comportamiento de de elementos como Rb, P, Ga/ Al, Y/Nb, K/Na, y Feo/Fe2O3, los índice de Rb/Nb, la proporción molar de los A/CNK y los diagramas ACF y A/CNK-Fe2O3+FeO), algunas de las cuales son consistentes con la índole I y otras con las índoles S y A, muestran que las rocas son granitoides híbridos y, en términos de orden tectónico, subyacen en la cadena WPG. De acuerdo con los índices Rb/Sr, Zr/Hf, K/Rb, los granitos fundieron la forma de los cuerpos sin desarrollarse completamente y sin registrar actividad magmática posterior, lo que llevó a la mineralización. Los índices Sm/Eu y Rb/Ba y el comportamiento del Rb, Ba y Sr al interior de los granitoides mencionados muestran que las rocas son similares al promedio de los granitoides no relacionados con los depósitos de Li, Be, Sn, W y Ta; estos incluyen en el rango de granitoides estériles, pero son parcialemente fértiles en Cu.</p><p><strong><br /></strong></p>

Abstract

Background.
Multiethnic societies face challenges in delivering evidence-based culturally competent health care. This study compared health-related quality of life and psychological morbidity in a hospital-based sample of first-generation migrants and Australian-born Anglo cancer patients, controlling for potential confounders related to migrant status. Further, it explored the relative contribution of ethnicity versus migrant-related variables.

Methods.
Eligible participants, recruited via 16 oncology clinics in Australia, included those over the age of 18, diagnosed with cancer (any type or stage) within the previous 12 months and having commenced treatment at least 1 month previously.

Results.
In total, 571 migrant patients (comprising 145 Arabic, 248 Chinese, and 178 Greek) and a control group of 274 Anglo-Australian patients participated. In multiple linear regression models adjusted for age, sex, education, marital status, socioeconomic status, time since diagnosis, and type of cancer, migrants had clinically significantly worse health-related quality of life (HRQL; 3.6–7.3 points on FACT-G, p &lt; .0001), higher depression and anxiety (both p &lt; .0001), and higher incidence of clinical depression (p &lt; .0001) and anxiety (p = .003) than Anglo-Australians. Understanding the health system (p &lt; .0001 for each outcome) and difficulty communicating with the doctor (p = .04 to .0001) partially mediated the impact of migrancy. In migrant-only analyses, migrant-related variables (language difficulty and poor understanding of the health system), not ethnicity, predicted outcomes.

Conclusion.
Migrants who develop cancer have worse psychological and HRQL outcomes than Anglo-Australians. Potential targets for intervention include assistance in navigating the health system, translated information, and cultural competency training for health professionals.
New Wine in Old Wineskins: General Administrative Procedure and Public Administration Reform in Croatia
Authors: Đulabić Vedran 
Published: March 2015

In 2009, Croatia adopted the new General Administrative Procedure Act (GAPA), which introduced several novelties in the regulation of general administrative procedure. The main research topic deals with the changes that the new GAPA, as an incentive for public administration reform in Croatia, has produced. The empirical data were collected within the EU funded IPA project “Support for the implementation of the General Administrative Procedure Act” (2012−2013) and interpreted on the basis of institutional theory. Despite changes to the legal text, the empirical data show that the new GAPA has not resulted in actual changes in everyday public administration.
Surge in Newly Identified Diabetes Among Medicaid Patients in 2014 Within Medicaid Expansion States Under the Affordable Care Act
Authors: Kaufman Harvey W. , Chen Zhen , Fonseca Vivian A. , McPhaul Michael J. 
Published: March 2015

OBJECTIVE
Twenty-six states and the District of Columbia expanded Medicaid in January 2014 pursuant to the Affordable Care Act (ACA); 24 states did not. This created an opportunity to examine the impact of Medicaid expansion on the number of Medicaid patients with newly identified diabetes among enrollees (19–64 years of age) who had laboratory testing through Quest Diagnostics.

RESEARCH DESIGN AND METHODS
Newly identified diabetes was defined as an ICD-9 diagnosis code of 250.x (diabetes) or hemoglobin A1c of &gt;6.4% (46 mmol/mol) within the first 6 months of a calendar year and the absence of both in the preceding calendar year within our data repository.

RESULTS
We identified 215,398 and 218,890 patients who met our definition of newly diagnosed diabetes within the first 6 months of 2013 (control period) and 2014 (study period), respectively (a 1.6% increase). We identified 26,237 Medicaid-enrolled patients with new diabetes in the control period vs. 29,673 in the study period: an increase of 13%. The number of Medicaid-enrolled patients with newly identified diabetes increased by 23% (14,625 vs. 18,020 patients) in the 26 states (and District of Columbia) that expanded Medicaid compared with an increase of 0.4% (11,612 vs. 11,653 patients) in the 24 states that did not expand Medicaid during this period. Similar differences were observed in younger and older adults and for both men and women.

CONCLUSIONS
This study suggests that in the states that expanded Medicaid under the ACA, an increased number of Medicaid patients with diabetes are being diagnosed and treated earlier. This could be anticipated to lead to better long-term outcomes.
Temporal processing and speech perception in quiet and noise across different degrees of ANSD
Authors: Narne Vijaya Kumar , Chatni Suma , Kalaiah Mohan Kumar , Chandan Hunsur Suresh , Deepthi Mahadeva , Barman Animesh 
Published: March 2015

Objective:
The aim of the present study was to examine the effect of degree of temporal processing impairment in adult listeners with ANSD on speech perception measures.

Study design:
Forty-six listeners with ANSD and 30 normal hearing listeners participated in the study. Temporal resolution was measured using the Temporal Modulation Transfer Function (TMTF). Speech identification scores in quiet were measured for bisyllabic words and Speech Reception Threshold in noise (SRTn) was measured for words. Furthermore, consonant identification was measured for 20 VCV stimuli.

Results:
Listeners with ANSD performed significantly worse than normal hearing listeners in both temporal resolution and speech perception measures. Peak sensitivity and 3dB cut-off frequency were estimated for each individual in both groups from the TMTFs data using an exponential fitting function. The listeners with ANSD were subgrouped into mild, moderate and severe degrees based on peak sensitivity. As the degree of temporal processing impairment increased, speech identification scores reduced and SRTn increased systematically. Similarly, consonant identification decreased with increase in temporal processing impairment. Among phonemic features, manner of articulation was better perceived compared to voice and place of articulation.

Conclusion:
The high correlation between temporal processing ability and speech perception suggests that temporal processing measures may be a potential tool for assessing the severity of ANSD in adult listeners.
Madagascar : le développement contrarié
Authors: Châtaigner Jean-Marc 
Published: March 2015

La crise malgache 2008-2013 ne s’inscrit pas comme un épisode accidentel et isolé de l’histoire de la Grande Île et des maux qui ont affecté ce pays depuis le xix e siècle. Les problèmes majeurs de la Grande Île, ceux qu’il lui faudra surmonter et vaincre pour retrouver les chemins de la croissance et d’un développement qui ne soit plus contrarié, s’appellent la mauvaise gouvernance, l’affairisme et le mauvais partage des richesses. Faute de mettre ces questions sur la table et d’y apporter des réponses, le risque pourrait être grand que cette sortie de crise ne conduise à une nouvelle implosion régressive (ou un énième « bond en arrière ») dans quelques années.
Une géographie de la France ludique. La dimension spatiale des pratiques culturelles
Authors: Borzakian Manouk 
Published: March 2015

Cet article entend démontrer l’intérêt d’une approche spatiale des pratiques ludiques et, plus largement, des pratiques culturelles, en s’appuyant sur une enquête consacrée à la distribution spatiale des licenciés français de six jeux institutionnels. Dans la lignée critique du modèle de la distinction, la cartographie de ces licenciés permet tout d’abord de confirmer les liens statistiques entre certains jeux et catégories socioprofessionnelles. Par ailleurs, ce type d’homologie peut être transposé des groupes sociaux aux portions d’espace – avec des pratiques fortement régionalisées – et plus encore aux types d’espace. Dans le premier cas, il n’existe pas toujours une cause structurelle identifiable; il demeure que l’impulsion de départ crée un contexte favorable, permettant au succès d’un jeu de s’autoentretenir. Dans le second cas, les variations de gradient d’urbanité constituent un important facteur explicatif des pratiques, opposant deux idéaux-types : la mono-activité des communes rurales et petites villes, et l’émergence dans les grands centres urbains de pratiques rares et diverses. Dans l’ensemble, l’enquête met en évidence le fait que les configurations spatiales participent à informer les goûts et leur perpétuation.
