Activating Tasks for the Study of Visual-Spatial Attention in ADHD Children: A Cognitive Anatomic Approach
Authors: Swanson James M. , Posner Michael , Potkin Steven , Bonforte Susan , Youpa Daniel , Fiore Chris , Cantwell Dennis , Crinella Frank
Published: February 2017

The clinical label attention deficit hyperactivity disorder (ADHD) suggests that this syndrome is a disorder of attention. However, the presumed attentional deficits have not been linked either to specific cognitive operations or to specific neural systems. To provide this link, theories of the cognitive anatomy of attention were used to generate hypotheses about specific visual-spatial attentional deficits in children with ADHD. A cued reaction-time test was used to assess covert and overt shifts of attention theoretically linked to two neuroanatomically defined attentional systems in the posterior and anterior parts of the human brain. The early, posterior-based covert shift of attention was found to be normal in ADHD children, but a later, anterior-based overt shift of attention was abnormal as reflected by a significant lateral difference in reaction time. This was interpreted as a failure to sustain focused attention. (J Child Neurol 1991;6(Suppl):S117-S125).
The Go-No Go Test in Attention Deficit Disorder Is Sensitive to Methylphenidate
Authors: Trommer Barbara L. , Hoeppner Jo-Ann B. , Zecker Steven G.
Published: February 2017

The go-no go test requires a subject to emit a simple motor response to one cue while inhibiting the response in the presence of another cue. This test has been effective in demonstrating impulsivity (elevated commission error rate) in children with attention deficit disorder (ADD). In this study, we examined the effects on go-no go test performance of two doses of methylphenidate (0.15 mg/kg and 0.3 mg/kg) administered in double-blind placebo-controlled fashion to children with ADD. Our results indicate that even modest doses of methylphenidate improve the go-no go performance of these children by decreasing their tendency to make impulsive commission errors. Thus the test is sensitive to the effects of methylphenidate and can be used to monitor a response to therapy. (J Child Neurol 1991; 6(Suppl):S126-S129).

Improving Charity Accountability: Lessons From the Scottish Experience
Authors: McDonnell Diarmuid
Published: February 2017

This article examines the relevance and effectiveness of a charity accountability monitoring program in Scotland. The Scottish charity sector is vibrant and growing but the regulatory regime is in flux. Drawing upon a novel panel dataset of 21,322 observations on 5,124 organizations for the period 2007-2013, this study examines charity accountability from the perspective of the regulator and analyzes its attempts to encourage acceptable norms and practices in the sector. The results reveal that a majority of these charities trigger accountability concerns and a minority do so persistently; however, this study finds no link between these concerns and negative organizational outcomes such as public complaints, regulatory intervention, or charity dissolution. The article suggests that Scotland’s regulatory body should collaborate with the charity sector to reconsider the program’s intended impact and priorities, and reflects on alternative indicators of accountability.
Pride Against Prejudice? The Stakes of Concealment and Disclosure of a Stigmatized Identity for Gay and Lesbian Auditors
Authors: Stenger Sebastien , Roulet Thomas J
Published: February 2017

How do individuals choose to conceal a stigmatized attribute and what are the consequences of such a choice? We answer this question by looking at how gay and lesbian employees make sense of their homosexuality in the highly normative context of audit firms. As a first step, we unveil the subtle pressures exerted on those who possess concealable stigmatized identities. Homosexual auditors engage in partial or full concealment of their sexuality. They live in the fear of being misjudged and cast out of a context in which male values are tantamount. However, the efforts required to conceal create a situation of unrest, which eventually interferes with their social integration at work. We draw on rich ethnographic material in French audit firms, benefitting from the exogenous shock of a gay marriage bill. The study’s findings shed new light on audit as a gendered profession and the cost of concealing stigmatized invisible identities.

Published: February 2017

For investigating the evolution process of a half flush-mounted air intake exit distortion in the downstream flow field and also its effects on the fan-stage performance, sub-system level numerical simulation of the whole structure of the air intake and the fan-stage was carried out. Considering large boundary layer ingestion, a scheme that bleeding air from stator for blowing control in the front air intake was also proceeded. At the same time, both the single fan-stage with uniform air admission and the single airintake without fan-stage are researched for comparison. The results show that giving a real exit boundary or not has significant impact on the airintake numerical simulation results, especially to the circumferential total pressure distortion and the swirl distortion at the airintake exit. Due to large boundary layer ingesting, the aerodynamic performance of the fan-stage declines a lot. As comparing with the homogeneous air admission condition, the maximum isentropic efficiency and the choked mass flow of the fan-stage decrease about 4.17% and 1.31%, respectively. After bleeding air from the stator, the overall performance of the fan-stage changes significantly. It improves a lot when the fan-stage works between the maximum efficiency point and the stall margin while decreases under other conditions. The distorted low energy fluid from upstream always covers several passages as it goes through the fan-stage. And in the meanwhile, severe flow separation appears at suction side of stator blades, no matter the bleed air flow control executed or not. Impact of the design of the bleed air pipe on the control effect is large, and the best bleed air pipe for flow control is needed to further research in the future.
Vibration and damping analysis of aerospace pipeline conveying fluid with constrained layer damping treatment
Authors: Gao Pei-xin , Zhai Jing-yu , Qu Fu-zheng , Han Qing-kai
Published: February 2017

The constrained layer damping materials are thoroughly used to control the vibration duo to their high capacity to dissipate vibration energy. Researchers have handled the vibration and damping behavior of the constrained layer damping structures accurately. However, for the constrained layer damping pipeline conveying fluid, there are few works on the investigation of the vibration characteristics. This paper is aimed to investigate the vibration and damping characteristics of the constrained layer damping pipeline conveying fluid under elastic boundary supports. Considering the fluid–structure interaction, the developed finite element method is employed to establish the motion equations of the constrained layer damping pipeline. The influence of the support stiffness, the fluid velocity and pressure, the thickness and the elasticity modulus of viscoelastic, and constraining layer parameters are all considered. The results indicate that an appropriate selection of the boundary support stiffness, the viscoelastic, and constraining layer parameters can obtain desirable modal properties, which can provide an efficient tool in the design and maintenance of aerospace pipeline for passive vibration control.
Examination of the Relationship Between Gender, Performance, and Enjoyment of a First-Person Shooter Game
Authors: Hopp Toby , Fisher Jolene
Published: February 2017

Purpose. The purpose of this work was to explore the relationship between gender, game performance factors, and player enjoyment of a first-person shooter (FPS) video game. Drawing upon the notion that FPS games are gendered spaces in which men are both the intended and ideal participants, we predicted that women’s game enjoyment, in contrast to men’s, would rest on their ability to positively violate negative expectancies associated with FPS games by performing at a high level.

Method. Two inter-related studies were employed. The first (preliminary) study used an online survey to assess gender-based expectancy differences. The second (main) study was lab-based. Here, participants played the FPS game COUNTER-STRIKE: GLOBAL OFFENSIVE and provided data on perceived game performance and session enjoyment.

Results. The data indicated that men’s enjoyment of a FPS game was not influenced by game performance while women’s enjoyment was, in fact, significantly influenced by both subjective self-relative and objective performance dimensions.

Conclusions. The present findings may provide a partial explanation for the persistence of the gender gap relative to FPS preference. Moreover, the current work extends the current scholarly understanding of expectancy value theory (EVT) by investigating the effect of expectancy violations associated with one’s own behavior.

Published: February 2017

Adherence to non-vitamin K antagonist oral anticoagulants (NOACs) is an important factor for ensuring efficacy and safety in nonvalvular atrial fibrillation (NVAF). There are controversial results regarding NOAC adherence in real-world data and there are no data about NOAC adherence in Turkish population. This study investigated the NOAC adherence based on self-report, factors affecting nonadherence, and the relation of the adherence level with efficacy and safety outcomes. This multicenter cross-sectional study included 2738 patients (59% female) using NOAC (dabigatran, apixaban, and rivaroxaban) due to NVAF for more than 3 months with >30 days of supply between September 1, 2015, and February 28, 2016. To measure the adherence level, an 8-item Morisky Medication Adherence Scale was used. The mean age of the patients was 70 ± 10 years. Of the 2738 patients, 44% were receiving dabigatran, 38% rivaroxaban, and 18% apixaban. A total of 630 (23%) patients had high medication adherence, 712 (26%) moderate adherence, and 1396 (51%) low adherence. Nonadherence had related to stroke (5.6% vs 2.5%, P < .001) and minor (21.2% vs 11.1%, P < .001) and major (6.1% vs 3.7%, P = .004) bleeding rates. The adherence to NOAC was found to be quite low in Turkey. Nonadherence is associated with bleeding and thromboembolic cardiovascular events. Age, taking NOAC twice a day, and the additional noncardiac diseases, depression, and dementia were the independent factors affecting poor medication adherence.
Analytical investigation of the acoustic behavior of nanocomposite porous media by using modified nonlocal Biot’s equations
Authors: Hasani Baferani A , Ohadi AR
Published: February 2017

In this paper, the modified Biot’s equations based on nonlocal elasticity theory are presented for modeling nanocomposite porous media. The analytical solution of modified Biot’s equations is obtained by using the recently developed potential function method. By doing some mathematical manipulation, the coupled modified Biot’s equations are converted to two decoupled equations. Consequently, the variations of field variables and acoustical properties of a considered nanocomposite foam are studied by changing the nonlocal parameter. The obtained results show that the local Biot’s results are in good agreement with the nonlocal modified Biot’s results for very small values of the nonlocal parameter. In addition, the values of field variables (i.e. pressure) in the thickness direction are decreased by increasing the nonlocal parameter for frequencies below 5000 Hz. Furthermore, by increasing the nonlocal parameter, the differences between local and nonlocal values of field variables and the absorption coefficient increase. Also, the nonlocal parameter has no considerable effect on the absorption coefficient for frequencies lower than 2000 Hz, whereas by increasing the nonlocal parameter the differences between corresponding results of local and nonlocal theories increase for frequencies above 2000 Hz.
Anemia and fatigue in cancer patients
Authors: Davidson Terri G
Published: February 2017

Although strong evidence indicates that fatigue can be caused by anemia, little is known about the relationship between the extent and rate of hemoglobin loss and the development of fa tigue. Anemia, an insufficiency of red blood cells to maintain adequate tissue oxygenation, is the most common hematologic abnormality associ ated with cancer. It usually results from a de crease in red blood cell production, resulting from either direct tumor invasion of bone mar row or the anemia of chronic disease. Fatigue is a subjective sensation, often described as tired ness, exhaustion, lethargy, or malaise. The mechanism that precipitates or sustains fatigue is probably multifactorial and includes the re lease of inflammatory cytokines and the onset of the acute-phase inflammatory response. Other factors that contribute to cancer-related fatigue include the underlying disease, treatment of the disease, intercurrent systemic illnesses, sleep disorders, immobility and lack of exercise, chronic pain, and psychosocial factors. A review of cancer-related anemia and fatigue is pre sented, which focuses on the clinical decision- making process regarding the management of these syndromes when they exist concurrently.
Haematology and coagulation profiles in cats with congenital portosystemic shunts
Authors: Tzounos Caitlin E , Tivers Michael S , Adamantos Sophie E , English Kate , Rees Alan L , Lipscomb Vicky J
Published: February 2017

Objectives

The objectives of this study were, first, to report the haematological parameters and coagulation times for cats with a congenital portosystemic shunt (CPSS) and the influence of surgical shunt attenuation on these parameters; and, second, to identify any association between prolongation in coagulation profiles and incidence of perioperative haemorrhage.

Methods

This was a retrospective clinical study using client-owned cats with a CPSS. Signalment, shunt type (extra- or intrahepatic), degree of shunt attenuation (complete or partial), haematological parameters, prothrombin time (PT) and activated partial thromboplastin time (aPTT) test results, and occurrence of any perioperative clinical bleeding complications were recorded for cats undergoing surgical treatment of a CPSS at the Royal Veterinary College, UK, between 1994 and 2011.

Results

Forty-two cats were included. Thirty-six (85.7%) had an extrahepatic CPSS and six (14.3%) had an intrahepatic CPSS. Preoperatively, mean cell volume (MCV) and mean cell haemoglobin (MCH) were below the reference interval (RI) in 32 (76.2%) and 31 (73.8%) cats, respectively. Red blood cell count and mean cell haemoglobin concentration (MCHC) were above the RI in 10 (23.8%) and eight (19.1%) cats, respectively. Postoperatively, there were significant increases in haematocrit ( P = 0.044), MCV ( P = 0.008) and MCH ( P = 0.002). Despite the significant increase in MCV postoperatively, the median MCV postoperatively was below the RI, indicating persistence of microcytosis. Preoperatively, PT was above the upper RI in 14 cats (87.5%), and aPTT was above the upper RI in 11 cats (68.8%). No cat demonstrated a perioperative clinical bleeding complication.

Conclusions and relevance

Cats with a CPSS are likely to present with a microcytosis, but rarely present with anaemia, leukocytosis or thrombocytopenia. Surgical attenuation of the CPSS results in a significant increase in the HCT and MCV. Coagulation profiles in cats with a CPSS are likely to be prolonged, irrespective of shunt type, but do not appear to be associated with an increased risk of clinical bleeding.

Authors: Rochel Daphné , Burger Myriam , Nguyen Patrick , Jaillardon Laetitia
Published: February 2017

Objectives

The aim of this study was to evaluate changes in circulating insulin-like growth factor type 1 (IGF-1) concentrations in hyperthyroid cats, before and after thiamazole treatment.

Methods

Thirty-four hyperthyroid cats were retrospectively included. Plasma free thyroxine (fT4) and IGF-1 concentrations were measured at diagnosis and 3 months after initiating antithyroid drug therapy.

Results

Median fT4 significantly decreased ( P <0.001) after treatment (from 78 pmol/l [range 43–122 pmol/l] to 31 pmol/l [range below assay limit of detection to 88 pmol/l]), whereas IGF-1 values significantly increased ( P <0.001) after treatment (from 117 ng/ml [33–341 ng/ml] to 221 ng/ml [36–865 ng/ml]). fT4 and IGF-1 concentrations were significantly negatively correlated both at diagnosis (r = −0.43, P = 0.01) and after treatment (r = −0.51, P = 0.002).

Conclusions and relevance

In cats, IGF-1 concentrations appear to be inversely proportional to the severity of hyperthyroidism and significantly increase after treatment with thiamazole.
Antithrombotic therapy in aortic diseases: A narrative review
Authors: Caron Francois , Anand Sonia S
Published: February 2017

Aortic diseases are a heterogeneous group of disorders, including atherothrombotic conditions like aortic atheroma, cholesterol embolization syndrome, aortic mural thrombus, thrombus within an aneurysm, and large vessel vasculitis. In this review, we provide a summary of the current evidence regarding atherothrombotic diseases of the aorta, focusing on therapeutic avenues. In patients with previous stroke, aortic arch atheroma is recognized as a strong predictor of recurrent atheroembolism, and antiplatelet therapy alone is still associated with a high (11.1%) residual risk of recurrent stroke. In secondary prevention, the use of dual antiplatelet therapy or moderate intensity anticoagulation with warfarin may lower the risk of recurrent stroke at a cost of increased life-threatening bleeding. Thrombi adherent to the aortic wall are generally associated with underlying atherosclerosis or aneurysmal disease. Primary aortic mural thrombus is a rare condition, sometimes related with systemic prothrombotic or inflammatory diseases. Retrospective studies suggest that anticoagulation is beneficial in patients with mobile mural thrombus. The pathogenesis and consequences of thrombus in an aortic aneurysm, or in an endograft following endovascular aneurysm repair, have been studied, but the role of antiplatelet therapy in those two conditions is still unclear and should be driven by general cardiovascular risk prevention. The benefit of anticoagulation to reduce thrombus load is uncertain. Patients with large vessel vasculitis experience increased cardiovascular events secondary to inflammation-driven atherothrombotic processes. Antiplatelet therapy is recommended as part of the therapy for prevention of cardiovascular disease. Anticoagulation with warfarin has shown limited benefit in few retrospective studies.
‘Do you want this?’ Exploring newcomer migrant girls’ peer reception in Norwegian day care: Experiences with social exclusion through the exchange of self-made artefacts
Authors: Kalkman Kris , Hopperstad Marit Holm , Valenta Marko
Published: February 2017

This article approaches newcomer migrant girls’ experiences with social competition and relational aggression. This the authors do through a detailed analysis of the interactional practices that a group of preschool-aged girls make use of as they socially exclude one of two newcomer migrant girls from participating in a sharing activity involving self-made artefacts. The data is drawn from ethnography combined with video recordings of natural and situated activities of the girls’ interactions in a Norwegian day-care institution over the course of nine months. Combining structural and social-constructivist perspectives, the authors discuss how a day-care group is a social field comprising multiple subfields characterized by agents struggling over position and power. Overall, this article addresses another side of the generally accepted positive view of day care for migrant children, revealing how relational aggression might be embedded within seemingly harmless activities and set in everyday child-governed activities. Finally, the authors reflect on implications for pedagogical practices and make suggestions for future research.
Defining the duty to contribute: Against the market solution
Authors: Furendal Markus
Published: February 2017

If there is a duty of justice to contribute to society, which asks individuals to produce a specific amount of goods and services that can be redistributed, we need a decision-procedure to know when we have done our part. This paper analyses and critically assesses the commonly suggested decision-procedure of relying on market prices to measure the value of one’s contribution. It is usually assumed that a high salary indicates that one’s talents are put to good use, but this presupposes both that market prices of labour are correct reflections of supply and demand, and that market prices are correct reflections of social value. I criticise both assumptions and argue that the social value of a contribution cannot simply be a function of its market value, but is also influenced by the principles of justice that support the duty to contribute. Further, the market solution is incapable of valuing contributions that lack market prices, like non-marketised care labour. The market solution thus fails as a decision-procedure under other than special circumstances. This does not mean, however, that we need to give up the idea of a duty to contribute.
Computation of the self-noise of a controlled-diffusion airfoil based on the acoustic analogy
Authors: Martínez-Lera P , Christophe J , Schram C
Published: February 2017

The self-noise of a controlled-diffusion airfoil is computed with several numerical techniques based on the acoustic analogy and involving different degrees of approximation. The flow solution is obtained through an incompressible large eddy simulation. The acoustic field as described by Lighthill’s analogy is computed with a finite element method applied to the exact airfoil geometry, and this solution is compared with results based on a half-plane Green’s function. This problem behaves as a classical trailing-edge noise problem for a wide range of frequencies; however, other mechanisms of sound production become significant at high frequencies. The results highlight the relative strengths and weaknesses of quadrupole- and dipole-based formulations of the acoustic analogy based on incompressible Computational Fluid Dynamics (CFD) results when applied to wall-bounded turbulent flows.
Cost-effective hybrid RANS-LES type method for jet turbulence and noise prediction
Authors: Mahak M , Naqavi IZ , Tucker PG
Published: February 2017

Jets at higher Reynolds numbers have a high concentration of energy in small scales in the nozzle vicinity. This is challenging for large-eddy simulation, potentially placing severe demands on grid density. To circumvent this, we propose a novel procedure based on well-known Reynolds number (Re) independent of jets. We reduce the jet Re while rescaling the boundary layer properties to maintain incoming boundary layer thickness consistent with high Re jet. The simulations are carried out using hybrid large-eddy simulation type of approach which is incorporated by using near-wall turbulence model with modified properties. No subgrid scale model is used in these simulations. Hence, they effectively become numerical large-eddy simulation with Reynolds-averaged Navier–Stokes covering the full boundary layer region. The noise post-processing is carried out using the Ffowcs-Williams-Hawking approach. The simulations are made for Mach numbers (M) of 0.75 and 0.875 (cold and hot). The results for the overall sound pressure level are observed to be within 2–3% of the measurements, and directivity of sound is also captured accurately for both the cases. Hence, the low Re simulations can be more beneficial in saving time and cost while providing reasonably accurate results.
Supreme Court Precedent in a Judicial Hierarchy
Authors: Masood Ali S. , Kassow Benjamin J. , Songer Donald R.
Published: February 2017

We offer a novel theory on Supreme Court impact that makes several key contributions beyond existing accounts. We argue that policy-oriented justices are particularly attentive to the impact of their precedents within the U.S. Courts of Appeals. We provide a framework in which both Supreme Court and circuit-level influences drive U.S. Courts of Appeals responses to the Supreme Court’s precedents. Principally, we argue that the Supreme Court’s use of its summary decisions, which explicitly reference its formally argued decisions, increase circuit court utility of the High Court’s precedents. We test our predictions using new data on appeals court responses to the Supreme Court’s precedents. The empirical results support our account and shed new light on the hierarchical dynamic within the American federal judiciary.
Role of ATP as a Key Signaling Molecule Mediating Radiation-Induced Biological Effects
Authors: Kojima Shuji , Ohshima Yasuhiro , Nakatsukasa Hiroko , Tsukimoto Mitsutoshi
Published: February 2017

Adenosine triphosphate (ATP) serves as a signaling molecule for adaptive responses to a variety of cytotoxic agents and plays an important role in mediating the radiation stress-induced responses that serve to mitigate or repair the injurious effects of γ radiation on the body. Indeed, low doses of radiation may have a net beneficial effect by activating a variety of protective mechanisms, including antitumor immune responses. On the other hand, ATP signaling may be involved in the radiation resistance of cancer cells. Here, focusing on our previous work, we review the evidence that low-dose γ irradiation (0.25-0.5 Gy) induces release of extracellular ATP, and that the released ATP mediates multiple radiation-induced responses, including increased intracellular antioxidant synthesis, cell-mediated immune responses, induction of DNA damage repair systems, and differentiation of regulatory T cells.

Authors: Li Xin , Huang Qiang , Chen Xuechao , Yu Zhangguo , Zhu Jinying , Han Jianda
Published: February 2017

This article presents a novel under-actuated robot hand, which has a thumb and two cooperative fingers. The thumb has two joints with 2 degrees of freedom driven by one motor. Each of the other two fingers has the same mechanism structure with the thumb and forms a cooperative mechanism, which is driven by only one motor with 4 degrees of freedom in total. All the under-actuated fingers are designed with the transmission mechanisms based on a kind of mechanism combined with the linkage mechanism and the passive elements. In this article, it is shown that under-actuated hand is able to reproduce most of the grasping behaviors of the human hand anthropomorphically and self-adaptively, without increasing the complexity of mechanism and control. The grasping stability analysis is given to help to understand the size range and load range of a stable grasp. Finally, the experiment results verify the high efficiency and stability of the novel mechanism.

Model-free adaptive optimal controller design for aeroelastic system with input constraints
Authors: Ji Nan , Xu Dezhi , Liu Fei
Published: February 2017

In this thesis, an innovative model-free adaptive control strategy based on a multi-observer technique that takes advantage of input/output measurement data is proposed for the aeroelastic system of the two degree of freedom pitch-plunge wing, and this unknown complicated nonlinear system is a general multi-input multi-output plant with input constraints. In this algorithm, the multi-observer technique is applied to estimate the value of the pseudopartial derivative parameter matrix in the approach of the compact form dynamic linearization designed to linearize the model of the two-dimensional wing-flap system with input constraints. At the same time, this model-free adaptive control method consists of the approximate internal model and the optimal controller. Moreover, this control scheme is based on the linear matrix inequalities, which is a kind of real-time computation. In the design process for controlling this two-dimensional wing-flap system in the condition that the control inputs are subjected to amplitude and change rate limits, the problem of the dynamic control is transformed into the optimization problem, which can minimize the performance index. Finally, simulation results for the two-dimensional wing-flap system with input constraints can demonstrate the availability and potential of the presented multi-observer-based model-free optimal control strategy for unknown nonlinear multi-input multi-output system with input saturation.

Published: February 2017

Ependymal tumours in adults are rare, accounting for less than 4% of primary tumours of the central nervous system, and exceptionally metastasise outside the nervous system. In this study, we present a case of anaplastic ependymoma, which developed metastases outside the nervous system less than a year after its clinical onset. A healthy 65-year-old woman suddenly presented with drowsiness of unknown origin, accompanied by ingravescent fatigue, inability to maintain the upright posture, headache, nausea and vomiting. Computed tomography study performed in the emergency department showed the presence of an inhomogeneously hypodense area, with temporoparietal extension and median line deviation. After surgical excision, performed after two days, the bioptic examination demonstrated an anaplastic ependymoma with multiple areas of necrosis. The patient was submitted to adjuvant radiation therapy. At magnetic resonance imaging follow-up, performed three months after surgery, neither local recurrences nor typical ‘drop metastases’ to the spinal area were observed. Three months later, magnetic resonance imaging control revealed bone metastases and recurrences in the left insula and at the ipsilateral cerebellar hemisphere. Total body computed tomography examination showed metastases in the liver, vertebrae and pelvic bones, and involvement of paratracheal lymph nodes.
Targeting patients with asthma for omalizumab therapy: choosing the right patient to get the best value for money
Authors: Al Said Abir , Cushen Breda , Costello Richard W
Published: February 2017

The asthma syndrome has many manifestations, termed phenotypes, that arise by specific cellular and molecular mechanisms, termed endotypes. Understanding an individual’s asthma phenotype helps clinicians make rational therapeutic decisions while the understanding of endotypes has led to the development of specific precision medications. Allergic asthma is an example of an asthma phenotype and omalizumab, a monoclonal antibody that neutralizes serum immunoglobulin (Ig)E, is a specific targeted treatment which was developed as a result of an understanding of the endotype of allergic asthma. Omalizumab has been widely used in clinical practice in Europe for over a decade as an add-on therapy to treat patients who have severe refractory allergic asthma. Over this period, many centres have reported their experience with omalizumab as an add-on therapy in patients with severe asthma. These ‘real world’ clinical effectiveness studies have confirmed the benefits, cost-effectiveness and clinical utility of this medication. Combining the outcomes of both sources of research has yielded important insights that may benefit patients with severe asthma, clinicians who treat them, as well as the funding agencies that reimburse the cost of this medication. The purpose of this review is to describe how to identify and evaluate a patient with asthma for whom treatment with omalizumab may be of clinical and cost-effective benefit. The assessment and investigations used to confirm allergic asthma, the objective assessment of adherence to asthma therapy and the expected benefits of add-on omalizumab treatment are described.
Art Perception in the Museum: How We Spend Time and Space in Art Exhibitions
Authors: Carbon Claus-Christian
Published: February 2017

Aesthetics research aiming at understanding art experience is an emerging field; however, most research is conducted in labs without access to real artworks, without the social context of a museum and without the presence of other persons. The present article replicates and complements key findings of art perception in museum contexts. When observing museum visitors ( N = 225; 126 female, M(age) = 43.3 years) while perceiving a series of six Gerhard Richter paintings of various sizes (0.26–3.20 sq. m) in a temporary art exhibition in January and February 2015 showing 28 paintings in total, we revealed patterns compatible to previous research. The mean time taken in viewing artworks was much longer than was mostly realized in lab contexts, here 32.9 s ( Mdn = 25.4 s). We were also able to replicate visitors spending more time on viewing artworks when attending in groups of people. Additionally, we uncovered a close positive relationship ( r2 = .929) between canvas size and viewing distance, ranging on average between 1.49 and 2.12 m ( M = 1.72 m). We also found that more than half of the visitors returned to paintings, especially those people who had not previously paid too much attention at the initial viewing. After adding the times of returning viewers, each picture was viewed longer than had been estimated in previous research ( M = 50.5 s, Mdn = 43.0 s). Results are discussed in the context of current art perception theories, focusing on the need for the ecologically valid testing of artworks in aesthetics research.

Aims:

Early infarct-related artery patency has been associated with improved outcomes in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention. However, it is unknown whether this relationship persists in contemporary practice with pre-hospital initiation of treatment, use of novel P2Y12 inhibitors and frequent use of drug-eluting stents. The purpose of the study was to determine the impact of early infarct-related artery patency on outcomes in the contemporary EUROMAX trial.

Methods and results:

A total of 2218 patients were enrolled. The current analysis was done on 1863 patients who underwent percutaneous coronary intervention and had infarct-related artery patency data. Thirty-day outcomes were compared according to infarct-related artery flow before percutaneous coronary intervention (Thrombolysis in Myocardial Infarction (TIMI) flow 0/1 vs. TIMI flow 2/3), and interaction with antithrombotic strategy was examined. A patent infarct-related artery (TIMI flow 2/3) was present in 707 patients (37.9%) and was associated with a higher rate of final TIMI 3 flow grade (98.9 vs. 92.6%; p<0.001). At 30 days, a patent infarct-related artery was associated with lower rates of cardiac death (1.3% vs. 2.9%; p=0.026) and the composite of death or myocardial infarction (2.7% vs. 4.6%; p=0.039). There were no interactions between antithrombotic treatment and the impact of infarct-related artery patency on cardiac death, myocardial infarction, or the composite of death or myocardial infarction (Breslow–Day interaction p-values of 0.21, 0.33 and 0.46, respectively).

Conclusion:

Despite evolution in primary percutaneous coronary intervention strategies, early infarct-related artery patency is still associated with higher procedural success and improved clinical outcomes. The choice of antithrombotic strategy did not interact with the benefits of a patent infarct-related artery at presentation.
Telecare – where, when, why and for whom does it work? A realist evaluation of a Norwegian project
Authors: Berge Mari S
Published: February 2017

Introduction

Evaluations of telecare demonstrate disparate results, which are of little help for understanding what the users need from further policy and development. This study aims to provide a more nuanced approach to telecare evaluations.

Methods

Realist evaluation is used to scrutinize what it is about telecare that works for whom, why, how and in which circumstances. Sequential interviews were conducted with telecare users and relatives at pre- and post-implementation stages.

Result

Some users experienced the intended effects from telecare, such as increased feeling of safety, whereas others did not. Various contextual elements influenced how people reasoned about the resources provided by telecare and affected the individual outcomes.

Discussion

The desire to remain in own home appeared to be a major driving force in accepting telecare. Users had surprisingly high tolerance to side effects of telecare, which might indicate that much was at stake. Some users disapproved of having telecare due to contextual reasons; however, readjustments proved successful to some.

Conclusion

This study illuminates how and why telecare works differently in different situations, and thus leads to different outcomes. When telecare is correctly adjusted to match the user’s needs, abilities and contexts it enables them to feel safe and remain in their own homes.
Micro-computed tomography and mechanical evaluation of trabecular bone structure in osteopenic and osteoporotic fractures

Published: February 2017

Purpose:

Osteopenia and osteoporosis are the two most common musculoskeletal disorders in the elderly population. We determined whether osteopenic and osteoporotic patients with fractures exhibit differences in trabecular morphology and biomechanical properties of bone.

Methods:

Fourteen osteopenic patients and 28 osteoporotic patients with hip fractures who underwent hemiarthroplasty for proximal femoral fractures caused by low-energy injury were included. Bone mineral density (BMD) measurements were performed. Compression tests and high-resolution micro-computed tomography were used to assess cancellous bone samples obtained from the principal compressive region of the femoral head.

Results:

The BMD values were lower in the osteoporotic patients than in the osteopenic patients ( p < 0.05). There was a significant difference in the yield stress values between the groups ( p < 0.05). However, no significant differences in the strain energy density, stiffness and Young’s modulus were observed between the groups ( p > 0.05). The mean maximum stress was significantly higher in the osteoporotic patients than in the osteopenic patients ( p < 0.05). Although structural parameters, including bone volume (BV), BV fraction, trabecular thickness, trabecular connectivity density and trabecular number, were higher in the osteopenic patients, the differences were not significant ( p > 0.05). Trabecular separation values were significantly higher in the osteoporotic patients ( p < 0.05).

Conclusion:

Our results showed that the trabecular morphology and biomechanical properties of bone were not significantly different between osteopenic and osteoporotic patients in terms of some parameters.
Faithful Doxology: The Church’s Allyship with Immigrants Seeking Asylum
Authors: Boursier Helen
Published: February 2017

Given the mass human movement from Central America to the United States, the church needs to rethink its mission strategy for its humanitarian involvement with these immigrants seeking asylum. Looking through the hermeneutical lens of practical theology and its attention to contextualized praxis, the article situates the argument in conversation with qualitative research that emerged from a pastoral care ministry inside an immigrant family detention facility. The voices of these Central American women and children seeking asylum serve to contextualize, localize, humanize, and testify to the unjust reality of mass migration. The proposal endorses a missional hermeneutic that prioritizes allyship with asylum seekers as the church’s witness to the justness of God.

From 1973 to 1985 Chuck and his wife, Jean, served in Chiapas, Mexico, in leadership formation. In 1981 Chuck received a Ph.D. in missiology under Johannes Verkuyl at the Free University of Amsterdam, followed by teaching mission theology in Michigan and, for twenty-seven years, at Fuller Theological Seminary. The Van Engens lead a ministry that provides PhD-level theological education to Latin American leaders.
Single cell sequencing: a distinct new field
Authors: Wang Jian , Song Yuanlin
Published: February 2017

Single cell sequencing (SCS) has become a new approach to study biological heterogeneity. The advancement in technologies for single cell isolation, amplification of genome/transcriptome and next‐generation sequencing enables SCS to reveal the inherent properties of a single cell from the large scale of the genome, transcriptome or epigenome at high resolution. Recently, SCS has been widely applied in various clinical and research fields, such as cancer biology and oncology, immunology, microbiology, neurobiology and prenatal diagnosis. In this review, we will discuss the development of SCS methods and focus on the latest clinical and research applications of SCS.
Gendering Landscapes of War Through the Narratives of Soldiers’ Mothers
Authors: Kaptan Senem
Published: February 2017

Despite being exempt from compulsory military service, women have been indispensable in their roles as mothers of conscripted soldiers in the conflict between the Turkish military and the Kurdistan Workers’ Party (PKK). Based on in-depth interviews conducted with twenty women in Istanbul whose sons were deployed to the conflict zone and returned home without any injuries, this article examines how the conflict has impacted the mothers’ perception of national service, of the Kurdish conflict, and of the “East.” I argue that the women start to partly question the obligation to serve once their children are asked to become the potential victims, and perpetrators, of the conflict. But this questioning does not develop into a full-fledged critique of the service and ends up reinforcing the tropes associated with Kurds and the “East” as backward, unruly, and resistant to change. Thus they mostly justify the modernizing mission of the military.
