Authors: Molaei Langroudi Roghieh , Ghazanfari Amlashi Fatemeh , Hedayati Emami Mohammad Hassan 
Published: July 2013

SummaryBackground: Spontaneous ovarian hyperstimulation syndrome (sOHSS) can occur following hypothyroidism. Ultrasonography facilitates diagnosis and monitoring of this syndrome. We describe ovarian sonographic changes in a hypothyroid patient with sOHSS after treatment with levothyroxine (l-T4).Case presentation: A 15-year-old girl presented with abdominal pain and distension for a few months. On examination, she had classical features of hypothyroidism. Abdominal and pelvic ultrasound revealed enlarged ovaries with multiple thin-walled cysts and mild ascitic fluid. On follow-up, abdominal ultrasound showed significant reduction of ovary size after 6 weeks of initiation ofl-T4. Normal ovary size with complete regression of ovarian cysts was seen after 4 months.Conclusion: Serial ultrasound in sOHSS associated with hypothyroidism showed regression of ovarian cysts and ovarian volume after 4 months whereas in other studies, it is reported to happen in various durations, presumably according to its etiology.Learning pointsOHSS can rarely occur due to hypothyroidism.This type of OHSS can be simply treated byl-T4replacement, rather than conservative management or surgery in severe cases.Ultrasound follow-up shows significant regression of ovarian size and cysts within 6 weeks of initiation ofl-T4.Ultrasound follow-up shows normal ovarian size with complete resolution of ovarian cysts 4 months after treatment.

Published: July 2013

Abstract
In this paper, we discuss nonlocal Cauchy problems for fractional order nonlinear differential systems. Firstly, an important matrix associated with fractional order and two functionals are constructed. Further, some sufficient conditions which guarantee such matrix convergent to zero matrix are presented. Secondly, by using three fixed point theorems via the techniques that use convergent to zero matrix and vector norm, some existence results for the solutions of such fractional order nonlinear differential systems are given under different conditions. Finally, some examples are given to illustrate the results.

Published: July 2013

BackgroundAlthough not well understood, foot kinematics are changed with hallux valgus.ObjectiveThe purpose of this study was to examine tarsal kinematics in women with hallux valgus deformity.DesignA prospective, cross-sectional design was used.MethodsTwenty women with (n=10) and without (n=10) deformity participated. Data were acquired with the use of a magnetic resonance scanner. Participants were posed standing to simulate gait, with images reconstructed into virtual bone datasets. Measures taken described foot posture (hallux angle, intermetatarsal angle, arch angle). With the use of additional computer processes, the image sequence was then registered across gait conditions to compute relative tarsal position angles, first-ray angles, and helical axis parameters decomposed into X, Y, and Z components. An analysis of variance model compared kinematics between groups and across conditions. Multiple regression analysis assessed the relationship of arch angle, navicular position, and inclination of the first-ray axis.ResultsBoth the hallux and intermetatarsal angles were larger with deformity; arch angle was not different between groups. The calcaneus was everted by ≥6.6 degrees, and the first ray adducted (F=44.17) by ≥9.3 degrees across conditions with deformity. There was an interaction (F=5.06) for the first-ray axis. Follow-up comparisons detected increased inclination of the first-ray axis over middle stance compared with late stance in the group with deformity.LimitationsGait was simulated, kinetics were not measured, and sample size was small.ConclusionsThere were group differences. Eversion of the calcaneus and adduction of the first ray were increased, and the first-ray axis was inclined 24 degrees over middle stance in women with deformity compared with 6 degrees in control participants. Results may identify risk factors of hallux valgus and inform nonoperative treatment (orthoses, exercise) strategies.

AbstractThe dependence of oxygen isotope fractionation on ice growth rate during the freezing of sea water is investigated based on laboratory experiments and field observations in McMurdo Sound, Antarctica. The laboratory experiments were performed in a tank filled with sea water, with sea ice grown under calm conditions at various room temperatures ranging from −5°C to −20°C. In McMurdo Sound, the ice growth rate was monitored using thermistor probes for first-year landfast ice that grew to ∼2 m in thickness. Combining these datasets allows, for the first time, examination of fractionation at a wide range of growth rates from 0.8 × 10−7 to 9.3 × 10−7 m s−1. In the analysis a stagnant boundary-layer model is parameterized using these two independent datasets. As a result, the optimum values of equilibrium pure-ice fractionation factor and boundary-layer thickness are estimated. It is suggested that a regime shift may occur at a growth rate of ∼2.0 × 10−7 m s−1. A case study on sea ice in the Sea of Okhotsk, where the growth rate is modeled by coupling the thermodynamic properties of the sea ice with meteorological data, demonstrates the utility of the fitted models.
Volume and velocity changes at Mittivakkat Gletscher, southeast Greenland

Published: July 2013

AbstractWe document changes for Mittivakkat Gletscher, the peripheral glacier in Greenland with the longest field-based observed mass-balance and surface velocity time series. Between 1986 and 2011, this glacier changed by −15% in mean ice thickness and −30% in volume. We attribute these changes to summer warming and lower winter snow accumulation. Vertical strain compensated for ∼60% of the elevation change due to surface mass balance (SMB) in the lower part, and ∼25% in the upper part. The annual mean ice surface velocity changed by −30%, which can be fully explained by the dynamic effect of ice thinning, within uncertainty. Mittivakkat Gletscher summer surface velocities were on average 50–60% above winter background values, and up to 160% higher during peak velocity events. Peak velocity events were accompanied by uplift of a few centimeters.
Le mécanisme bancaire et l'interprétation des statistiques monétaires
Authors: Raillon J. 
Published: July 2013

La masse monétaire comprend à la fois les billets de banque et les dépôts à vue. Quand on considère l'ensemble du système bancaire (Banques - Banque de France), il se manifeste une certaine équivalence entre la masse monétaire et les emplois sous forme : a. d'achats d'or et de devises ; b. de créances sur le Trésor et c. de prêts à l'économie.
Cette interdépendance, mise en évidence dans les statistiques du Conseil national du Crédit, est l'une des caractéristiques essentielles du mécanisme du système bancaire. Il en est de même du fait que l'expansion des dépôts est liée à celle des billets et inversement, ce qui renforce la solidarité entre les Banques et la Banque de France.
En pratique, interviennent les mécanismes de la compensation et du marché monétaire, qui sont l'objet d'explications particulièrement précises.
Les fluctuations de la masse monétaire et de ses contreparties peuvent être ainsi analysées plus facilement. Le rôle du déficit des finances publiques et de l'excédent des payements extérieurs est notamment souligné.
Tensions inflationnistes et conjoncture occidentale
Authors: Hérouville Hubert d' 
Published: July 2013

Les disponibilités monétaires mises directement au service du secteur privé sont en forte augmentation moyenne, dépassant celle du Produit national.
La masse des revenus des salariés (traitements et salaires) est aussi en progrès sensible depuis 1950 par rapport à l'évolution du Produit national moyen. Les revenus du capital, après un recul relatif apparent en 1952 et 1953, ont vivement progressé en 1954 et 1955. Les revenus agricoles et individuels sont en retard par rapport aux autres.
Le déficit moyen de la balance commerciale s'accroît en 1955 (sauf quelques exceptions, dont la France), surtout en ce qui concerne la zone dollar. Le stock d'or, ou les réserves en devises étrangères, ont fléchi dans les pays où se font sentir les tensions inflationnistes.
Le taux des salaires est en hausse, et n'a pas d'effet inflationniste quand il se tient dans les limites de l'augmentation de la productivité. Le taux d'escompte et la plupart des taux d'intérêts viennent d'être relevés, pour éviter certains excès de crédit et limiter la consommation.
Les prix, assez stables en moyenne jusqu'à la mi-1955, sont toutefois orientés à la hausse au Royaume-Uni et en Scandinavie, où les tensions inflationnistes sont les plus anciennes et les plus sensibles. Sur les marchés mondiaux, les prix agricoles baissent et ceux des matières premières sont en augmentation. Ce dernier fait contribue au mouvement général de hausse, encore modéré, qui semble s'amorcer depuis la fin de 1955.
Les réactions psychologiques transitoires : interculturation et personnalité interculturelle
Authors: Teyssier Julien , Denoux Patrick 
Published: July 2013

Les contacts entre les cultures et leur diversité au sein des sociétés, entraînent de nombreuses conséquences dont certaines affectent directement les dynamiques identitaires. En partant de ce constat, a été élaborée une théorie de la personnalité interculturelle, s’enracinant dans une perspective interactionniste (Goffman, 1982 ; Bruner, 1991) reposant sur le paradigme selon lequel l’Homme crée l’extériorité qui crée l’Homme. Cette réciprocité donne aux réactions psychologiques transitoires une place centrale, en soulignant que ce processus permet l’adaptation intrapsychique à l’extériorité en dessinant sans cesse les contours de la fiction identitaire du sujet.
Regards sur les villes libyennes aujourd'hui
Authors: Romanet Perroux Jean-Louis , Bennafla Karine 
Published: July 2013

Alors que les institutions de l’Etat peinent à s’affirme en Libye, ce pays est aujourd’hui à mi-chemin entre un Etat-nation et une confédération de villes-Etats. On y reconnaît l’argument de Charles Tilly selon lequel la guerre construit l’Etat. En effet, les cinq villes d’où proviennent les seules milices qui jouissent d’une envergure nationale, sont celles qui de fait exercent les pouvoirs régaliens sur leur territoire. Le pouvoir opérationnel et la légitimité de ces milices, ou plus exactement de ces groupes de milices, dérivent directement du rôle qu’elles ont joué durant la révolution (février-octobre 2011). Ce pouvoir physique et moral d’une poignée de villes libyennes garantit une certaine stabilité au pays, mais il représente aussi un danger majeur pour l’Etat, les institutions démocratiques et le développement d’une économie formelle et libre. Une chose est certaine : pour comprendre la réalité libyenne actuelle, il faut tout d’abord regarder l’échelon des villes. Mais il est tout aussi certain qu’une Libye forte et démocratique ne se développera qu’en dépassant les clivages territoriaux et tribaux. C’est là où la société civile a un rôle majeur à jouer.

Perception Versus Reality: A Comparative Study of the Clinical Judgment Skills of Nurses During a Simulated Activity
Authors: Fenske Cynthia L. , Harris Margaret A. , Aebersold Michelle L. , Hartman Laurie S. 
Published: July 2013

Background:
This study was conducted to determine how closely nurses’ perceptions of their clinical judgment abilities matched their demonstrated clinical judgment skills during a simulation.

Methods:
Seventy-four registered nurses participated in a simulation using a video format. After the simulation, the nurses self-assessed their performance using the Lasater Clinical Judgment Rubric. This rubric was then used to rate the nurses’ actual performance in the simulation activity.

Results:
The study results showed a significant discrepancy between nurses’ perceptions of their own clinical judgment abilities and their demonstrated clinical judgment skills. Age and length of nursing experience enhanced the difference between the findings of self-assessment and actual performance.

Conclusion:
Younger nurses and those with 1 year or less of nursing experience were significantly more likely to have self-assessed their abilities at a much higher level compared with their actual skills.

Published: July 2013

Surgical precision in oncologic surgery is essential to achieve adequate margins in bone tumor resections. Three-dimensional preoperative planning and bone tumor resection by navigation have been introduced to orthopedic oncology in recent years. However, the accuracy of preoperative planning and navigation is unclear. The purpose of this study was to evaluate the accuracy of preoperative planning and the navigation system.
A total of 28 patients were evaluated between May 2010 and February 2011. Tumor locations were the femur (n=17), pelvis (n=6), sacrum (n=2), tibia (n=2), and humerus (n=1). All resections were planned in a virtual scenario using computed tomography and magnetic resonance imaging fusion. A total of 61 planes or osteotomies were performed to resect the tumors. Postoperatively, computed tomography scans were obtained for all surgical specimens, and the specimens were 3-dimensionally reconstructed from the scans. Differences were determined by finding the distances between the osteotomies virtually programmed and those performed. The global mean of the quantitative comparisons between the osteotomies programmed and those obtained through the resected specimen was 2.52±2.32 mm for all patients.
Differences between osteotomies virtually programmed and those achieved by navigation intraoperatively were minimal.

Abstract
Developing an HIV-1 vaccine has been hampered by the inability of immunogens to induce broadly neutralizing Abs (BnAbs) that protect against infection. Previously, we used knockin (KI) mice expressing a prototypical gp41-specific BnAb, 2F5, to demonstrate that immunological tolerance triggered by self-reactivity of the 2F5 H chain impedes BnAb induction. In this study, we generate KI models expressing H chains from two other HIV-1 Abs, 4E10 (another self-/polyreactive, anti-gp41 BnAb) and 48d (an anti-CD4 inducible, nonpolyreactive Ab), and find a similar developmental blockade consistent with central B cell deletion in 4E10, but not in 48d VH KI mice. Furthermore, in KI strains expressing the complete 2F5 and 4E10 Abs as BCRs, we find that residual splenic B cells arrest at distinct developmental stages, yet exhibit uniformly low BCR densities, elevated basal activation, and profoundly muted responses to BCR ligation and, when captured as hybridoma mAb lines, maintain their dual (gp41/lipid) affinities and capacities to neutralize HIV-1, establishing a key role for anergy in suppressing residual 2F5- or 4E10-expressing B cells. Importantly, serum IgGs from naive 2F5 and 4E10 KI strains selectively eliminate gp41 and lipid binding, respectively, suggesting B cells expressing 2F5 or 4E10 as BCRs exhibit specificity for a distinct spectrum of host Ags, including selective interactions by 2F5 BCR+ B cells (i.e., and not 4E10 BCR+ B cells) with those mimicked by its gp41 neutralization epitope.
Approximation of H(div) with High-Order Optimal Finite Elements for Pyramids, Prisms and Hexahedra
Authors: Bergot Morgane , Duruflé Marc 
Published: July 2013

AbstractClassical facet elements do not provide an optimal rate of convergence of the numerical solution toward the solution of the exact problem in H(div-norm for general unstructured meshes containing hexahedra and prisms. We propose two new families of high-order elements for hexahedra, triangular prisms and pyramids that recover the optimal convergence. These elements have compatible restrictions with each other, such that they can be used directly on general hybrid meshes. Moreover the H(div) proposed spaces are completing the De Rham diagram with optimal elements previously constructed for H1 and H(curl) approximation. The obtained pyramidal elements are compared theoretically and numerically with other elements of the literature. Eventually, numerical results demonstrate the efficiency of the finite elements constructed.

IntroductionDespite the rapid expansion of antiretroviral therapy (ART) programmes in developing countries, pre‐treatment losses from care remain a challenge to improving access to treatment. Youth and adolescents have been identified as a particularly vulnerable group, at greater risk of loss from both pre‐ART and ART care. Point‐of‐care (POC) CD4 testing has shown promising results in improving linkage to ART care. In Khayelitsha township, South Africa, POC CD4 testing was implemented at a clinic designated for youth aged 12–25 years. We assessed whether there was an associated reduction in attrition between HIV testing, assessment for eligibility and ART initiation.MethodsA before‐and‐after observational study was conducted using routinely collected data. These were collected on patients from May 2010 to April 2011 (Group A) when baseline CD4 count testing was performed in a laboratory and results were returned to the clinic within two weeks. Same‐day POC CD4 testing was implemented in June 2011, and data were collected on patients from August 2011 to July 2012 (Group B).ResultsA total of 272 and 304 youth tested HIV‐positive in Group A and Group B, respectively. Group B patients were twice as likely to have their ART eligibility assessed compared to Group A patients: 275 (90%) vs. 183 (67%) [relative risk (RR)=2.4, 95% CI: 1.8–3.4, p<0.0001]. More patients in World Health Organization (WHO) Stage 1 disease (85% vs. 69%), with CD4 counts≥350 cells/µL (58% vs. 35%) and more males (13% vs. 7%) were detected in Group B. The proportion of eligible patients who initiated ART was 50% and 44% (p=0.6) in Groups B and A, respectively; and 50% and 43% (p=0.5) when restricted to patients with baseline CD4 count≤250 cells/µL. Time between HIV‐testing and ART initiation was reduced from 36 to 28 days (p=0.6).DiscussionPOC CD4 testing significantly improved assessment for ART eligibility. The improvement in the proportion initiating ART and the reduction in time to initiation was not significant due to sample size limitations.ConclusionsPOC CD4 testing reduced attrition between HIV‐testing and assessment of ART eligibility. Strategies to improve uptake of ART are needed, possibly by improving patient support for HIV‐positive youth immediately after diagnosis.
Ribosomal RNA Depletion for Efficient Use of RNA‐Seq Capacity
Authors: O'Neil Dominic , Glowatz Heike , Schlumpberger Martin 
Published: July 2013

AbstractRibosomal RNA (rRNA) is the most highly abundant component of RNA, comprising the majority (>80% to 90%) of the molecules present in a total RNA sample. Depletion of this rRNA fraction is desirable prior to performing an RNA‐seq reaction, so that sequencing capacity can be focused on more informative parts of the transcriptome. This unit describes an rRNA depletion method based on selective hybridization of oligonucleotides to rRNA, recognition with a hybrid‐specific antibody, and removal of the antibody‐hybrid complex on magnetic beads.

A series of chemical explosions, called the Source Physics Experiments (SPE, see Table ), is being conducted under the auspices of the U.S. Department of Energy's National Nuclear Security Administration (NNSA) to develop a new, more physics‐based paradigm for nuclear test monitoring. Improvements in technical capabilities resulting from such development have the potential to help the United States keep better tabs on underground nuclear tests being conducted worldwide and to enhance treaty monitoring.

AbstractBackgroundThe interaction between workers and safety representatives (SRs), a factor that determines SRs' effectiveness, is an unexplored issue within occupational health research.MethodsWe undertook a qualitative exploratory interpretative–descriptive study by means of semi‐structured interviews with SRs from Barcelona (Spain) to analyze the SRs' perspective on the interaction with workers and its determinantsResultsSRs' interaction with workers is mainly limited to information processes and to identifying occupational hazards. Prominent factors determining this interaction are associated with the way SRs understand and carry out their role, the firm sector and size, and workers' fear of dismissal, exacerbated by changes in the labor market and the current economic crisis.ConclusionsInteraction with workers is influenced by a more prevalent technical–legal view of the SRs' role and by unequal power relations between workers and management. Poor interaction with workers might lead to decreasing SRs' effectiveness. Am. J. Ind. Med. 57:338–350, 2014. © 2013 Wiley Periodicals, Inc.
