Published: February 2019

To improve patient dental care, it is necessary to identify possible risk factors for the failing of restorations. This practice-based cohort study investigated the performance and influence of possible risk factors at the level of the practice, patient, tooth, and restoration on survival of direct class II restorations. Electronic patient files from 11 Dutch general practices were collected, and 31,472 restorations placed between January 2015 and October 2017 were analyzed. Kaplan-Meier statistics were performed; annual failure rates (AFRs) were calculated; and variables were assessed by multivariable Cox regression analysis. The observation time of restorations varied from 0 to 2.7 y, resulting in a mean AFR of 7.8% at 2 y. However, wide variation in AFRs existed among the operators, varying between 3.6% and 11.4%. A wide range of patient-related variables is related to a high risk for reintervention: patient age (elderly: hazard ratio [HR], 1.372), general health (medically compromised: HR, 1.478), periodontal status (periodontal problems: HR, 1.207), caries risk and risk for parafunctional habits (high: HR, 1.687), restorations in molar teeth (HR, 1.383), restorations placed in endodontically treated teeth (HR, 1.890), and multisurface restorations (≥4 surfaces: HR, 1.345). Restorations placed due to fracture were more prone to fail than restorations placed due to caries. When patient-related risk factors were excluded, remaining risk factors considerably changed in their effect and significance: the effect of operator, age of the patient, and endodontic treatment increased; the effect of the diagnosis decreased; and the socioeconomic status became significant (high: HR, 0.873). This study demonstrated that a wide variation of risk factors on the practice, patient, and tooth levels influences the survival of class II restorations. To provide personalized dental care, it is important to identify and record potential risk factors. Therefore, we recommend further clinical studies to include these patient risk factors in data collection and analysis.
ACC Plasticity Maintains Masseter Hyperalgesia Caused by Occlusal Interference

Published: February 2019

Acute occlusal interference following improper occlusal alteration in dental practice can induce chronic masticatory muscle pain. The underlying mechanism has not been clarified. Synaptic plasticity in the anterior cingulate cortex (ACC) plays a key role in the chronic pain state. This study investigated the role of synaptic plasticity in the ACC in acute occlusal interference–induced chronic masticatory muscle pain. A rat model of experimental occlusal interference (EOI) was established. In vivo local field potential (LFP) recording was conducted to evaluate the change of synaptic strength and plasticity from the medial thalamus (MT) to the ACC after EOI application. The effects of microdialysis of antagonists of glutamate receptors into the ACC on synaptic transmission from the MT to the ACC were examined. Furthermore, the influence of inhibiting glutamate receptors in the ACC on EOI-induced mechanical hyperalgesia in the masseter muscles of rats was investigated. The amplitude of LFP in the ACC evoked by MT stimulation was significantly potentiated since 14 d of EOI application. Long-term potentiation of LFP in the ACC was reliably induced by theta burst stimulation to the MT in control rats but was occluded in 14-d EOI rats. Microdialysis of AMPA/kainate receptor antagonist CNQX into the ACC attenuated LFP in the ACC evoked by stimulating the MT in control and EOI rats. Administration of NMDA receptor subunit NR2B antagonist Ro 25-6981 into the ACC significantly alleviated the potentiation of MT stimulation-evoked LFP in the ACC of EOI rats without affecting that in control rats. EOI-induced hyperalgesia in the bilateral masseter muscles of rats was dose-dependently relieved after microdialysis of Ro 25-6981 into ACC. These findings provide direct evidence that prolonged acute occlusal interference potentiates synaptic transmission in the ACC, which in turn mediates chronic masticatory muscle pain.
Market Intelligence Dissemination Practices
Authors: Gebhardt Gary F. , Farrelly Francis J. , Conduit Jodie
Published: February 2019

Market intelligence is a cornerstone of the marketing concept and essential to market-focused strategic planning and implementation. Although the importance of market intelligence is widely accepted, how managers can ensure the organization-wide generation, dissemination, and responsiveness to market intelligence remains a persistent challenge. In this article, the authors investigate market intelligence dissemination practices and their resulting managerial responses. Using qualitative methods, the authors identify five market intelligence dissemination practices that either update and reinforce organization members’ existing schemas (mental models) of the market or create new, shared schemas of the market. Specifically, they find that the creation, existence, or absence of organizationally shared market schemas is crucial in explaining the effectiveness of different market intelligence dissemination practices. Thus, in addition to being experts on market intelligence, intelligence directors must be authorities on organizational learning and ways to create shared meaning structures that enable disseminated intelligence to be understood and used within their organizations. The authors conclude with suggestions for practitioners on how to manage intelligence dissemination across their organizations more effectively and efficiently.
Access to Qualified, Well-Supported Principals Across Alternative Educational Settings and Neighborhood Schools

Published: February 2019

Principals bear primary responsibility for supporting teachers. Principal leadership is especially important in alternative educational settings (AES; e.g., alternative schools, self-contained special education schools) that serve students with more substantial learning and behavioral needs, often with less-qualified and experienced teachers. We examined principals’ qualifications (i.e., principal certifications, preparation, and experience) and professional learning opportunities across AES and neighborhood schools. Analyzing data from the 2011–2012 Schools and Staffing Survey, we found that AES principals are, on average, less qualified than neighborhood school principals in terms of their experience, preparation, and administrative certification. Furthermore, AES principals have less access to professional development opportunities. Results are consistent with prior investigations that indicate an inequitable distribution of personnel resources in AES compared with neighborhood schools.
Brain stem death – an overview
Authors: Saran JSRG , Padubidri Jagadish R
Published: February 2019

The concept of brain death has been a very intriguing topic and has taken many forms over the years. Brain stem death is a complex state of inactivity defined by the loss of reflexes of the pathways that pass through the brain stem, the ‘shaft’ of the brain which links the spinal cord to the cerebral cortex and the cerebellum where there is apnoea, loss of eye movement and pain sensation. There are many criteria, based on which a person can be said to be brain dead. The best recognised of these are the Harvard, Minnesota and Philadelphia criteria. India follows the UK notion of brain stem death, and the Transplantation of Human Organs Act was passed in 1994 by the Indian parliament, which legalised brain-stem death, and in 1995 ordered the brain death certification procedure, which is certified by a ‘Board of Medical Experts’. Also, there are some legal and ethical implications that have to be considered in cases of disagreement in diagnosis among the panel of doctors, time of death in cases when patients’ relatives disagree or request more time for organ donation or to disconnect the life support system. In routine clinical practice, the issues pertaining to brain stem death should be dealt with by experienced physicians, counselling the family members or relatives and educating them about organ donation.
‘Post-race’ racisms in the narratives of ‘Brexit’ voters
Authors: Patel Tina G. , Connelly Laura
Published: February 2019

Although a growing body of scholarship seeks to understand the motivations behind the ‘Brexit’ vote – including that which centralises explorations of racism, nationalism and post-colonialism – little consideration has been given to the ways in which ‘post-race’ racisms underpin the narratives of Leave voters. This article draws on data generated through 13 semi-structured interviews to examine the subtle and subterranean ways in which xeno-racism is articulated in the accounts of some Leave voters in the Greater Manchester city of Salford: a city that saw a higher percentage of the electorate (56.8%) vote to leave the EU than the national average (51.9%). Whilst restricting immigration was a key motivator of Leave voters in our research, interviewees vehemently rejected accusations of racism. Instead, couching their views in seemingly non-racial ways, they framed their concerns about immigration as a ‘legitimate’ response to a victimised whiteness. Thus, in discussing our data, we argue that far from living in a ‘post-racial’ epoch, racisms continue to thrive through new modes of articulation. These new racisms emerge from the shadows at key times, such as the EU Referendum, and refashion themselves in ways that are considered more palatable than the older (explicit) racisms of past.

Published: February 2019

Cirrhotic patients with ascites are at high risk of developing spontaneous bacterial peritonitis (SBP). After exclusion of patients with acute kidney injury (AKI) or other infections, urinary neutrophil gelatinase-associated lipocalin (NGAL) levels were compared between two matched groups of Egyptian cirrhotic patients with ascites, mostly secondary to hepatitis C infection (98%). Group 1 had SBP (n = 41) and group 2 did not (n = 45). By univariate analysis, urinary-NGAL, high total bilirubin, serum creatinine, international normalised ratio and the Model of End-Stage Liver Disease (MELD) score and low platelet count were all significantly correlated with the presence of SBP, but only urinary-NGAL could independently predict development of SBP ( P = 0.001). Urinary-NGAL at a cut-off value of 1225 pg/mL, showed a sensitivity of 95% and a specificity of 76%, and is therefore a most useful tool.
The Moderating Effect of Female Managers on Job Stress and Emotional Labor for Public Employees in Gendered Organizations: Evidence From Korea
Authors: Yun Jung Ah (Claire) , Lee Yunsoo , Mastracci Sharon
Published: February 2019

Given its focus on customer satisfaction and quality service, emotional labor (EL) is a prominent topic in public administration. As public employees are engaged more often in EL, it is critical to explore determinants of job stress and management strategies to reduce it. By examining the Korean Working Conditions Survey, this study focused on EL’s effects on employees’ well-being—job stress and job satisfaction—as well as the potential moderating effects of workplace characteristics, such as working with a female manager, work–life balance programs or resources, and participatory management processes. We examined the potential moderating role of female managers engaged in EL in gendered institutions, and found evidence that female managers buffer EL’s negative effects on their employees, even in organizational contexts gendered deeply. This finding implies that EL needs to be considered in the context of organizational culture and environment, particularly when related to gendered, hierarchical, or masculine organizations.
Settlement and employment outcomes of black African immigrants in Southeast Queensland, Australia
Authors: Udah Hyacinth , Singh Parlo , Chamberlain Susanna
Published: February 2019

In this paper, we focus on the economic integration of black African immigrants settling in Queensland by examining their experiences and views on employment within Australia's labor market. The paper draws on findings from a qualitative study conducted in Southeast Queensland. The study examines how black African immigrants define their identity, socio-economic wellbeing and sense of belonging in white majority Australia. The findings suggest that settlement and integration policies in Australia need to be informed by immigrants' employment experiences. The paper contributes to the literature on the role of employment in the settlement and integration processes of racially and culturally different immigrants.
Inverse optimal control of a class of affine nonlinear systems
Authors: Prasanna Parvathy , Jacob Jeevamma , Nandakumar Mattida Ponnadiyil
Published: February 2019

This paper proposes a systematic formulation of inverse optimal control (IOC) law based on a rather straightforward reduction of control Lyapunov function (CLF), applicable to a class of second-order nonlinear systems affine in the input. This method exploits the additional design degrees of freedom resulting from the non-uniqueness of the state dependent coefficient (SDC) formulation, which is widely used in pseudo-linear control techniques. The applicability of the proposed approach necessitates an apparently effortless SDC formulation satisfying an SDC matrix criterion in terms of the structure and characteristics of the state matrix, [Formula: see text]. Subsequently, a sufficient condition for the global asymptotic stability (g.a.s) of the closed-loop system is established. The SDC formulations conforming to the sufficient condition ensure the existence and determination of a smooth radially unbounded polynomial CLF of the form [Formula: see text], while offering a benevolent choice for the gain matrix [Formula: see text], in the CLF. The direct relationship between the gain matrix [Formula: see text] and state weighing matrix [Formula: see text] ensures optimization of an equivalent [Formula: see text]. This feature enables one to rightfully choose the gain matrix [Formula: see text] as per the performance requisites of the system. Finally, the application of the proposed methodology for the speed control of a permanent magnet synchronous motor validates the efficacy and design flexibility of the methodology.
Removal of heavy metal ions from wastewater by capacitive deionization using polypyrrole/chitosan composite electrode
Authors: Zhang Yujie , Xue Quanqin , Li Fei , Dai Jizhe
Published: February 2019

A polypyrrole/chitosan composite material was obtained by chemical polymerization. The adsorption performance of a hot-molded polypyrrole/chitosan composite electrode was tested by adsorption/desorption experiments. Scanning electron microscopy and Fourier-transform infrared spectroscopy both showed the deposition of polypyrrole on the chitosan surface. The specific capacitance of the polypyrrole/chitosan composite was determined by cyclic voltammetry in 1.0 M KCl at 0.01 V/s as 102.96 F/g. The adsorption/desorption experiments indicated that the specific adsorption capacity of the composite for Cu2+ was 99.67 mg/g, while the removal performance for other metal ions, such as Ag+, Pb2+, and Cd2+, was good. The results of multicycle adsorption/desorption tests showed that the adsorption rate of the polypyrrole/chitosan composite electrode for Cu2+ was decreased from 56.4 to 51.4% over 10 cycles, demonstrating the stable metal-ion adsorption/desorption behavior of the composite electrode. The obtained performances show that the prepared polypyrrole/chitosan composite material is an ideal electrode material for the removal of heavy metal ions.
Cross state-dependency of learning between 5-HT1A and/or 5-HT7 receptor agonists and muscimol in the mouse dorsal hippocampus
Authors: Jafari-Sabet Majid , Nemati Sepehr , Torab Mansour
Published: February 2019

Background:

Dysfunction of the serotonergic and GABAergic systems in cognitive disorders has been revealed. Understanding the neurobiological mechanisms of drug-associated learning and memory formation may help treatment of cognitive disorders.

Aims:

The aim of the present study was to investigate: 1) 8-OH-DPAT (5-HT1A agonist), AS19 (5-HT7 agonist) and muscimol (GABA-A agonist) on memory retrieval and state of memory, 2) cross state-dependent learning between 8-OH-DPAT and/or AS19 and muscimol.

Methods:

The dorsal hippocampal CA1 regions of adult male NMRI mice were bilaterally cannulated, and all drugs were microinjected into the intended sites of injection. A single-trial step-down inhibitory avoidance task was used for the evaluation of memory retrieval and state of memory.

Results:

Post-training and/or pre-test 8-OH-DPAT, AS19 and muscimol induced amnesia. Pre-test microinjection of the same doses of 8-OH-DPAT, AS19 and muscimol reversed the post-training 8-OH-DPAT-, AS19- and muscimol-induced amnesia, respectively. This event has been named state-dependent learning (SDL). The amnesia induced by 8-OH-DPAT was reversed by muscimol and induced 8-OH-DPAT SDL. The amnesia induced by muscimol was reversed by 8-OH-DPAT and induced muscimol SDL. The amnesia induced by AS19 was reversed by muscimol and induced AS19 SDL. The amnesia induced by muscimol was reversed by AS19 and induced muscimol SDL. Pre-test administration of a selective GABA-A receptor antagonist, bicuculline, 5 min before muscimol, 8-OH-DPAT and AS19 dose-dependently inhibited muscimol-, 8-OH-DPAT- and AS19-induced SDL, respectively.

Conclusions:

The results strongly revealed a cross SDL among 8-OH-DPAT and/or AS19 and muscimol in the dorsal hippocampal CA1 regions.
Influence of Peer Reactions and Student Attitudes on Student Deviance: Differences Between Japan and the United States
Authors: Kobayashi Emiko , Farrington David P.
Published: February 2019

The current study examines the cross-cultural applicability of Akers’ social learning theory in explaining why Japanese commit fewer deviant acts than Americans. It is predicted that deviance would be less common in Japan because Japanese have less favorable attitudes toward deviance, which in turn are attributable to less favorable peer reactions to deviance. Analyses of comparable survey data from college students in Japan ( N = 583) and the United States ( N = 615) provide mixed support for our arguments. As expected, Japanese students had less favorable attitudes toward deviance because they had peers who reacted less favorably to deviance. Contrary to expectation, however, even after controlling for student attitudes toward deviance and peer reactions to deviance, the initially large difference between the two samples in student deviance remained significant. This was at least partly because, in Japan, compared with the United States, peer reactions and student attitudes had significantly less influence on student deviance.
Increased cerebral responses to salient transitions between alternating stimuli in chronic migraine with medication overuse headache and during migraine attacks
Authors: Bogdanov Volodymyr B , Bogdanova Olena V , Viganò Alessandro , Noirhomme Quentin , Laureys Steven , Dallel Radhouane , Phillips Christophe , Schoenen Jean
Published: February 2019

Introduction

In a previous study exploring central pain modulation with heterotopic stimuli in healthy volunteers, we found that transitions between sustained noxious and innocuous thermal stimulations on the foot activated the “salience matrix”. Knowing that central sensory processing is abnormal in migraine, we searched in the present study for possible abnormalities of these salient transitional responses in different forms of migraine and at different time points of the migraine cycle.

Methods

Participants of both sexes, mostly females, took part in a conditioned pain modulation experiment: Migraineurs between (n = 14) and during attacks (n = 5), chronic migraine patients with medication overuse headache (n = 7) and healthy volunteers (n = 24). To evoke the salience response, continuous noxious cold or innocuous warm stimulations were alternatively applied on the right foot. Cerebral blood oxygenation level dependent responses were recorded with fMRI.

Results

Switching between the two stimulations caused a significant transition response in the “salience matrix” in all subject groups (effect of the condition). Moreover, some group effects appeared on subsequent post-hoc analyses. Augmented transitional blood oxygenation level dependent responses in the motor cortex and superior temporal sulcus were found in two patient groups compared to healthy controls: chronic migraine with medication overuse headache patients and migraineurs recorded during an attack. In chronic migraine with medication overuse headache patients, salience-related responses were moreover greater in the premotor cortex, supplementary motor area, lingual gyrus and dorso-medial prefrontal cortex and other “salience matrix” areas, such as the anterior cingulate and primary somatosensory cortices.

Conclusion

This study shows salience-related hyperactivation of affective and motor control areas in chronic migraine with medication overuse headache patients and, to a lesser extent, in episodic migraine patients during an attack. The greater extension of exaggerated blood oxygenation level dependent responses to unspecific salient stimuli in chronic migraine with medication overuse headache than during a migraine attack could be relevant for headache chronification.
Safety and tolerability of calcitonin-gene-related peptide binding monoclonal antibodies for the prevention of episodic migraine – a meta-analysis of randomized controlled trials
Authors: Xu Da , Chen Deng , Zhu Li-na , Tan Ge , Wang Hai-jiao , Zhang Yu , Liu Ling
Published: February 2019

Aim

To systematically evaluate the safety and tolerability of calcitonin-gene-related peptide binding monoclonal antibodies from the results of randomized controlled trials.

Methods

Online databases were searched on calcitonin-gene-related peptide binding monoclonal antibodies for the prevention of episodic migraine. Overall withdrawal, withdrawal due to adverse events, adverse events, serious adverse events and specific adverse events were extracted from the included studies. A meta-analysis was performed with Revman 5.3.0 software.

Results

Ten studies that investigated four drugs (galcanezumab, erenumab, fremanezumab and eptinezumab) with 5817 participants were included in this study. Serious adverse events, overall withdrawals, withdrawal due to adverse events and any adverse events were not significantly associated with monoclonal antibody treatment. Injection site pain and erythema were significantly higher in the calcitonin-gene-related peptide binding monoclonal antibodies treatment group than in the placebo group. The rates of serious adverse events were significantly higher in the galcanezumab 120 mg group. Injection site erythema was associated with galcanezumab 120 mg and 240 mg. Injection site pain and nasopharyngitis were associated with galcanezumab 150 mg and 5 mg, respectively. Overall adverse events were significantly higher with erenumab 70 mg and 140 mg. Treatment-related adverse events were significantly higher with fremanezumab 225 mg/month and 675 mg/quarter.

Conclusions

This study provides data on the safety and tolerability profiles of calcitonin-gene-related peptide binding monoclonal antibodies and confirms their potential use as preventive treatments for episodic migraine. In addition to the acceptable withdrawal rates, serious adverse events were rare, and the severity of most adverse events was mild to moderate. Injection site reaction may be the major adverse event associated with galcanezumab.
Phenylethynyl-terminated oligoimides with ultra-low melt viscosity derived from 1,4-bis(3,4-dicarboxy phenoxy)benzene dianhydride
Authors: Wang Wei , Chen Guofei , Fang Xingzhong
Published: February 2019

Most of the existing polyimide oligomers for resin transfer molding (RTM) processing exhibited high melt viscosity, which can only maintain below 1 Pa·s at 280°C for 2 h, leading to very high process temperatures. So novel RTM-type oligomers with lower and stable melt viscosities are more desirable. Three series of thermoset oligoimides derived from 1,4-bis(3,4-dicarboxy phenoxy)benzene dianhydride and three different aromatic diamines were prepared herein. The diamines included 4,4′-oxydianiline, 2,2′-bis(trifluoromethyl)benzidine (TFDB), and 2-phenyl-4,4′-diaminodiphenyl ether ( p-ODA). 4-Phenylethynylphthalic anhydride was used as an endcapping reagent. Effects of the chemical structures and molecular weights of the oligoimides on their aggregated structures, melt processability, and the thermal and mechanical properties of the cured films were then systematically investigated. X-Ray diffraction results indicated that ODA series oligoimides and TFDB series oligoimides showed crystallinity in various degrees. However, the asymmetric p-ODA enables the p-ODA series oligoimides to exhibit amorphous forms. It was found that the p-ODA-based oligoimide with a molecular weight of 750 g mol−1 showed very low melt viscosity of 1 Pa·s even at 210°C, and the melt viscosity could maintain below 1 Pa·s after isothermal aging for 2 h at any temperature in the range of 200–280°C by rheological measurements. The cured film also showed a high glass transition temperature of 355°C by dynamic mechanical analysis, very good thermal stability by thermogravimetric analysis, and good mechanical properties. It might be more suitable for RTM processes in the future.
Using a Psychopharmacogenetic Approach To Identify the Pathways Through Which—and the People for Whom—Testosterone Promotes Aggression

Little is known about the neurobiological pathways through which testosterone promotes aggression or about the people in whom this effect is observed. Using a psychopharmacogenetic approach, we found that testosterone increases aggression in men ( N = 308) with select personality profiles and that these effects are further enhanced among those with fewer cytosine-adenine-guanine (CAG) repeats in exon 1 of the androgen receptor (AR) gene, a polymorphism associated with increased AR efficiency. Testosterone’s effects were rapid (~30 min after administration) and mediated, in part, by subjective reward associated with aggression. Testosterone thus appears to promote human aggression through an AR-related mechanism and to have stronger effects in men with the select personality profiles because it more strongly upregulates the subjective pleasure they derive from aggression. Given other evidence that testosterone regulates reward through dopaminergic pathways, and that the sensitivity of such pathways is enhanced among individuals with the personality profiles we identified, our findings may also implicate dopaminergic processes in testosterone’s heterogeneous effects on aggression.
A distributed swarm control for an agricultural multiple unmanned aerial vehicle system
Authors: Ju Chanyoung , Son Hyoung Il
Published: February 2019

In this study, we propose a distributed swarm control algorithm for an agricultural multiple unmanned aerial vehicle system that enables a single operator to remotely control a multi-unmanned aerial vehicle system. The system has two control layers that consist of a teleoperation layer through which the operator inputs teleoperation commands via a haptic device and an unmanned aerial vehicle control layer through which the motion of unmanned aerial vehicles is controlled by a distributed swarm control algorithm. In the teleoperation layer, the operator controls the desired velocity of the unmanned aerial vehicle by manipulating the haptic device and simultaneously receives the haptic feedback. In the unmanned aerial vehicle control layer, the distributed swarm control consists of the following three control inputs: (1) velocity control of the unmanned aerial vehicle by a teleoperation command, (2) formation control to obtain the desired formation, and (3) collision avoidance control to avoid obstacles. The three controls are input to each unmanned aerial vehicle for the distributed system. The proposed algorithm is implemented in the dynamic simulator using robot operating system and Gazebo, and experimental results using four quadrotor-type unmanned aerial vehicles are presented to evaluate and verify the algorithm.
Why no board-level employee representation in Italy? Actor preferences and political ideologies
Authors: Leonardi Salvo , Gottardi Donata
Published: February 2019

Unlike most continental EU countries, Italy lacks any system of board-level employee representation, despite a specific article in the 1948 Constitution. Hence, involvement and participation remain limited to the sphere of contractually established information and consultation rights, primarily because of the reluctance of the social partners to establish reciprocal responsibilities by law. Employers feared that this would limit their property rights and prerogatives, unions that it would restrict their own autonomy. After a long history of confrontational industrial relations, there has been a shift towards participatory approaches, but in a distinctive way. We present an overview of the historical background and the cultures and practices of the main actors, the Italian approach to industrial democracy, the influence of other national models and the current debates and legislative proposals. We conclude by assessing the opportunities for and obstacles to real change in the future.
Recurrent Pain and Academic Achievement in School-Aged Children: A Systematic Review
Authors: Ragnarsson Susanne , Myleus Anna , Hurtig Anna-Karin , Sjöberg Gunnar , Rosvall Per-Åke , Petersen Solveig
Published: February 2019

Recurrent pain and school failures are common problems in children visiting the school nurses office. The overall aim of the current study was to investigate the relationship between recurrent pain and academic achievement in school-aged children. Literature was searched in seven electronic databases and in relevant bibliographies. Study selection, data extraction, and study and evidence quality assessments were performed systematically with standardized tools. Twenty-one studies met the inclusion criteria and 13 verified an association between recurrent pain (headache, stomachache, and musculoskeletal pain) and negative academic achievement. Two longitudinal studies indicated a likely causal effect of pain on academic achievement. All studies had substantial methodological drawbacks and the overall quality of the evidence for the identified associations was low. Thus, children’s lack of success in school may be partly attributed to recurrent pain problems. However, more high-quality studies are needed, including on the direction of the association and its moderators and mediators.
Assessment of Late Thromboembolic Complications Post–Fontan Procedure in Relation to Different Antithrombotic Regimens: 30-Years’ Follow-up Experience
Authors: Al-Jazairi Abdulrazaq S. , Al Alshaykh Hana A. , Di Salvo Giovanni , De Vol Edward B. , Alhalees Zohair Y.
Published: February 2019

Background: The current CHEST guidelines recommend the use of antithrombotic therapy, either aspirin or warfarin, as a primary thromboembolic complications (TECs) prophylaxis in patients who undergo Fontan procedure, without specification on drug selection or duration of therapy. Objective: To investigate the incidence rate of late TECs, occurring after 1-year post–Fontan procedure and to assess the difference in rate of late TECs between warfarin and aspirin. Methods: A retrospective cohort study included patients who had Fontan procedures between 1985-2010 at our institution. Patients were stratified according to the antithrombotic regimen—warfarin, aspirin, or no therapy—at the time of TECs. Results: We screened 499 patients who underwent Fontan procedures; 431 procedures met the inclusion criteria. Over a median follow-up of 13.6 years (IQR= 8.7), freedom from late TECs at 5, 10, 15, and 20 years was 97.54%, 96.90%, 90.78%, and 88.07%, respectively. There was no difference in late TEC incidence rates per 1000 patient-years between warfarin and aspirin: 7.82 and 5.83 events, respectively; rate ratio= 1.34 (95% CI= 0.68-2.60). Warfarin was associated with a higher major bleeding incidence rate per 1000 patient-years: 3.70 versus 2.91 events with aspirin; rate ratio= 1.27 (95% CI= 0.49 to 3.29). Conclusion and Relevance: The incidence rate of late clinical TECs post–Fontan procedure in our population is low. Warfarin was not superior to aspirin for prevention of late TECs. Yet warfarin was associated with a higher rate of bleeding. This finding suggests a simpler antithrombotic regimen for prevention of TEC after 1-year post-Fontan procedure.
Preparing Students for the Fight Against False Information With Visual Verification and Open Source Reporting
Authors: Walker Amy Schoenfeld
Published: February 2019

While some journalists analyze and verify “open source” materials such as social media, eyewitness video, and satellite imagery to hold leaders and institutions accountable, many journalists and students are not learning basic digital verification skills. Research shows that journalists find this work challenging and that newsrooms do not consistently offer resources. Educators can fill this gap, and address problems the press faces in a post-truth age, such as student overtrust of digital sources, public distrust of the media, and the advancement of tools to fake visual information. This essay offers exercises and resources for educators in a variety of settings.
The effect of natural and synthetic antioxidants and packaging type on the quality of cooked poultry products during frozen storage
Authors: Karpińska-Tymoszczyk Mirosława , Draszanowska Anna
Published: February 2019

The effect of oil-soluble rosemary extract, sodium erythorbate and their mixture, and the influence of packaging method (air and vacuum packaging) on the quality of cooked turkey meatballs stored at −20 ℃ was determined. The smallest changes in malondialdehyde content were observed in samples with the addition of the natural antioxidant regardless of the packaging method. The mixture of synthetic and natural antioxidants was more effective in retarding lipid oxidation than the synthetic antioxidant, and more desirable results were observed in vacuum-packaged samples than in air-packaged samples. The samples with the addition of oil-soluble rosemary extract were characterised by lower intensity of red colour, but this parameter was more stable during frozen storage. The results of a sensory analysis revealed that the application of oil-soluble rosemary extract with or without sodium erythorbate significantly inhibited the development of warmed-over flavour in cooked poultry products.
‘This weather always gets me down’: A psychosocial perspective on mental illness
Authors: Baur Nicole
Published: February 2019

Since antiquity, attempts to conceptualise the aetiology of mental illness have included social constructionist, biomedical, and psychosocial theories. The change of these concepts over the centuries is reflected in therapeutic approaches as well as the location, layout and interior design of psychiatric institutions. This article focuses on the genealogy of one of these concepts – the proposed link between meteorological parameters, specifically air and sun, and mental illness. Based on detailed archival materials, including administrative records, medical notes and correspondence as well as oral histories, relating to the Devon County Mental Hospital near Exeter (UK), it traces this link over time within and beyond the medical community to the extent that it served as pretext for underlying social causes of the illness. In doing so, this article makes an empirical contribution to geographical perspectives on the construction of psychiatric institutions throughout history while also advancing such work in theoretical terms by drawing attention to the shifts in medical and lay conceptualisations of mental illness.

Involving and engaging the public are crucial for effective prioritisation, dissemination and implementation of research about the complex interactions between environments and health. Involvement is also important to funders and policy makers who often see it as vital for building trust and justifying the investment of public money. In public health research, ‘the public’ can seem an amorphous target for researchers to engage with, and the short-term nature of research projects can be a challenge. Technocratic and pedagogical approaches have frequently met with resistance, so public involvement needs to be seen in the context of a history which includes contested truths, power inequalities and political activism. It is therefore vital for researchers and policy makers, as well as public contributors, to share best practice and to explore the challenges encountered in public involvement and engagement. This article presents a theoretically informed case study of the contributions made by the Health and Environment Public Engagement Group to the work of the National Institute for Health Research (NIHR) Health Protection Research Unit in Environmental Change and Health (HPRU-ECH). We describe how Health and Environment Public Engagement Group has provided researchers in the HPRU-ECH with a vehicle to support access to public views on multiple aspects of the research work across three workshops, discussion of ongoing research issues at meetings and supporting dissemination to local government partners, as well as public representation on the HPRU-ECH Advisory Board. We conclude that institutional support for standing public involvement groups can provide conduits for connecting public with policy makers and academic institutions. This can enable public involvement and engagement, which would be difficult, if not impossible, to achieve in individual short-term and unconnected research projects.
Temporal focus, emotions, and support for intergroup aggression

Emotions play an important role in conflict and aggression between groups. Two studies examined the link between temporal focus (past vs. future) and emotion (anger vs. fear) in the context of the threat of terrorism. Study 1 showed that manipulating emotion (fear vs. anger) in the context of terrorist threat against the United States induced different temporal foci. Fear elicited a future focus, whereas anger elicited a past focus. Study 2 manipulated temporal focus (past vs. future) and showed an increase in anger versus fear, respectively. These concordant emotional responses predicted support for intergroup aggression, as did political conservatism and beliefs in American superiority. Anger, but not fear, mediated the effect of past versus future framing on support for aggression. These results support temporal focus as a previously unconsidered but important determinant of the link between emotions and support for intergroup aggression.
Who is “German” and who is a “migrant?” Constructing Otherness in education and psychology research
Authors: Moffitt Ursula , Juang Linda P
Published: February 2019

Despite growing European and global interconnectedness, questions of national identity have only gained in importance in recent years. Yet the role researchers play in perpetuating norms of national belonging has gone largely unexamined. Who is included in unmarked national group labels such as German, Dutch, or Danish, who is understood as Other, and how terminology relates to exclusionary notions of national identity warrants greater investigation. Thus, using an exploratory review of recent research in the German context, the current study aimed to (a) identify relevant terminology in empirical education and psychology studies; (b) employ constructionist analysis to examine its situated meaning; (c) discuss societal and methodological implications; and (d) propose guidelines for more accurate and inclusive research. Based on a constructionist thematic analysis, a reiteration of a white ingroup and perceived immigrant Other was found. This dichotomy reinforces an exclusionary notion of who is German while omitting relevant information, such as participant generation or citizenship, from analyses. In doing so, researchers are perpetuating essentialized notions of national belonging while reporting incomplete and potentially inaccurate findings. Though selecting demographic information can be complex, recognizing the impact of labels and acknowledging heterogeneity are essential elements of inclusive and representative research.

This study summarizes the literature about alcohol- and drug-related public violence in Europe. The proportion of all public violent incidents linked to alcohol was about 50 percent in the UK and ranged from 26 percent to 43 percent in Germany, Austria and the Netherlands. Public violence related to drugs is much lower (1.5–18.0 percent). Relatively many public violent incidents occur in relation to nightlife (80 percent of alcohol-related incidents). Though a considerable proportion of public violence was alcohol or drug related, the actual use of such substances was rarely ascertained in perpetrators’ specimens. Such analysis is a prerequisite to heavier penalize alcohol- or drug-intoxicated perpetrators of public violence. More capacity should be deployed to measure alcohol and drugs in the specimens of violent perpetrators by analytical-chemical tests. As a result, more accurate estimates of substance-related public violence are obtained, which will serve policy makers and police enforcement officials to take measures for securing a safer public environment and sustainable nightlife industry in the future.

Although cardiac myxomas have been known to cause acute ischemic stroke and other cerebrovascular complications, intracranial embolization of metastatic tumor fragments is rare. This is likely because venous emboli generally cause pulmonary embolism. Pulmonary vein metastases and patent foramen ovales have previously shown to propagate intracranial embolic carcinomas, but these events are very uncommon, and are not well characterized. We report a rare case of large-cell, high-grade neuroendocrine lung cancer embolus occluding the basilar artery, which likely detached into the bloodstream from the lung after intruding into a pulmonary vein. The embolus was treated with endovascular aspiration, and achieved modified Thrombolysis In Cerebral Infarction 2c revascularization. After initial neurological recovery, the patient suffered respiratory arrest and support was withdrawn 48 h later. We discuss the tumor characteristics and implications for treatment of acute ischemic stroke in patients with cancer diagnoses.
Malleable Methodologies: Sculpting and Imagination in Embodied Health Research
Authors: Kriger Debra
Published: February 2019

Health research is complex, often asking questions that have uncertain, indefinite, or inarticulate answers. Embodied health research, which incorporates subjectivity and social relationships centered on the body, adds further complexity. There exist several calls for embodied research methodology, and it is now important to explore aligning methods and further develop embodied health research methodology. Using artistic and interview data from the Beyond the Present: Risk and Body Stigma in Public Health project, this article argues that imagination is a useful methodology and sculpting a fruitful method to draw out health stories. Sculpting and imagination allow material and conceptual malleability and are valuable in addressing complexity and uncertainty in critical qualitative health research.

Background

Atrial fibrillation is an important risk factor for stroke but there are limited data on atrial fibrillation-related stroke from the Middle East.

Methods

We interrogated the Qatar Stroke Database to establish the occurrence, clinical features, and outcomes of atrial fibrillation-related stroke at Hamad General Hospital, the sole provider of acute stroke care in Qatar.

Results

A total of 4079 patients (81.4% male, mean age 55.4 ± 13.3 years) were enrolled in the stroke database between January 2014 and 21 October 2017. Atrial fibrillation was present in 260 (6.4%) patients, of whom 106 (2.6%) had newly diagnosed atrial fibrillation. The National Institute of Health Stroke Scale (NIHSS) was significantly higher (7.9 + 7.0 (median 6; IQR 11) vs. 5.9 + 6.4 (median 4; IQR 6), P < 0.001) in atrial fibrillation patients. The modified Rankin Score (mRS) (P < 0.001) and mortality at 90-day follow-up (P = 0.002) were significantly higher in atrial fibrillation compared to non-atrial fibrillation stroke patients.

Conclusion

We demonstrate a low rate of atrial fibrillation and stroke in Qatar, perhaps reflecting the relatively young age of these patients. Atrial fibrillation-related strokes had higher admission NIHSS, greater disability, and higher mortality at 90 days when compared to non-atrial fibrillation strokes.
