AbstractAimThis study evaluated the role of preterm birth and fetal growth restriction on white matter maturation in schoolchildren without any severe neurodevelopmental impairment.MethodsThe study group comprised 56 very preterm children and 21 term children born between November 1998 and November 2002 at Oulu University Hospital, Finland. The mean gestational age of the preterm children was 28.7 (24.1–31.9) weeks. All children underwent diffusion tensor imaging at a mean age of 9.0 (8.6–9.6) years. Voxel‐wise statistical analyses of the imaging data were carried out using tract‐based spatial statistics.ResultsPreterm children with fetal growth restriction had lower fractional anisotropy and higher radial diffusivity than term controls (p < 0.05), bilaterally in several white matter areas. Preterm children without fetal growth restriction had higher mean diffusivity and axial diffusivity than term controls (p < 0.05) in analogous areas, but more asymmetrically.ConclusionPreterm children had microstructural differences in white matter, compared to term‐born children at a mean age of nine, and those with poor fetal growth showed widespread changes in white matter maturation compared to term‐born children. Fetal growth and prematurity seemed to affect white matter maturation in a way that was still visible at that age.

AbstractThis study investigates local expert perceptions of the role of environmental factors, especially in terms of contemporary climate change, in population movements from Bangladesh to India. The aim is to delve into locally held understandings of the phenomenon and to gain a better understanding of these migration processes, which are actively intertwined with local experiences. Both Indian and Bangladeshi experts were interviewed using semi‐structured, in‐depth interviews in order to explore insights from locally held perceptions and understandings of contextual factors. In total, 10 Bangladeshi and 15 Indian experts were interviewed, covering different disciplines, sectors, regions and job types, together providing a more complete and grounded picture of views of environmentally induced migration in Bangladesh and India. The results show that climate change is perceived by local experts as one of the key factors influencing migration in Bangladesh, both internally and externally. The interviewees, however, placed environmentally induced migration in a broader context of labour and economic migration. In particular, migration for environmental reasons in Bangladesh was evident long before the emergence of climate change as an issue. According to the interviewed experts, this does not preclude increased environmentally induced migration within and from Bangladesh in the future, but its analyses ought to be placed in historical and economical contexts.

AbstractHigh mortality rates have been reported for methadone in both adults and children. We aimed to determine the pattern of toxicity, possible underlying diseases and treatment challenges in patients referred to our centre with early diagnosis of methadone toxicity and who later died. Medical files of all methadone‐poisoned patients who had been admitted to a referral centre of toxicology between March 2011 and March 2016, died during the hospital stay and sent for autopsy to Legal Medicine Organization were retrospectively evaluated. In a total of 94 patients, autopsy findings and laboratory evaluations showed that cause of death was pure methadone toxicity in 57 (60.6%). Other causes of death were ischaemic heart disease in ten, co‐ingestions (toxicities including methadone) in eight, brain haemorrhage, multi‐organ failure and pneumosepsis (each in four), meningitis/encephalitis in three and head trauma and other toxicities (other than methadone but including an opioid, each in two) patients. Time of cardiopulmonary arrest was significantly different between those with pure methadone toxicity and those who died due to other causes (p = 0.01). Patients who had died due to co‐ingestions and other toxicities were younger (p = 0.029) and took more bolus doses of naloxone (p = 0.042). In methadone users, especially in older ages and those with trivial response to naloxone administration, loss of consciousness should not be strictly attributed to methadone toxicity. In such patients, thorough evaluation for other possible causes of loss of consciousness is mandatory.

In Turkey, responsive behaviors toward kin are expected from children. Despite this, we know little about the factors that influence young Turkish children's prosocial behaviors. The goal was to explore how temperament and parenting are related to children's prosocial development in Turkey. A total of 293 Turkish children (Mage = 49 months; 48.12% females) were followed up for 3 years. Mothers completed measures of their child's prosocial behaviors, as well as measures of their warmth, inductive reasoning, and the child's approach and reactivity. Maternal warmth predicted children's reactivity, and maternal induction predicted children's sociability. Children's reactivity was inversely related to children's helping behavior and sociability was related to more prosocial behavior. Maternal warmth had indirect links with helping through lessening children's reactivity.

Published: June 2017

To understand the conditions fostering positive outcomes of inclusive schooling, this two‐wave study examined the role of individual change in trust and sympathy for adolescents' cross‐group friendships and inclusive attitudes toward students with low academic achievement. Cross‐group friendships, intergroup trust, intergroup sympathy, and inclusive attitudes were obtained from surveys completed by 1,122 Swiss adolescents (Mage T1 = 11.54 years,Mage T2 = 12.58 years) from 61 school classes. Results from a parallel latent change score model revealed that the number of cross‐group friendships positively related to individual change in trust and sympathy; this growing trust and sympathy in turn predicted adolescents' inclusive attitudes. These findings are discussed regarding theories of intergroup contact and inclusive schooling.

Published: June 2017

AbstractObjectivesThis follow‐up study (1) compares tooth displacement of central incisors in patients with and without pre‐implant orthodontic treatment and (2) investigates whether sex, age, or orthodontic retention have an effect on tooth displacement after the insertion of single‐crown implants.Materials and MethodsFifty‐seven patients – thirty‐seven with (test group) and twenty without pre‐implant orthodontic treatment (control group) – were rehabilitated with 89 single‐crown implants in the upper maxilla. Clinical and radiographic data, clinical photographs, and dental casts were collected during baseline examinations after prosthetic rehabilitation and at the final follow‐up examination at least 5 years later. A total of 114 dental casts were digitalized and aligned using a software program to measure changes in the positions of the central incisors.ResultsAfter a follow‐up period of at least five years, 87% of the central incisors measured in the test group were displaced >0.25 mm vertically compared with 70% in the control group. Seventy‐eight percent of the test group teeth had moved >0.25 mm horizontally compared with 55% in the control group. These differences were not significant, and there were no significant correlations with patient age or sex.ConclusionThe majority of patients had minor vertical (60%) or horizontal (67%) tooth displacement of the central incisors (0.25–0.75 mm) after a minimum follow‐up period of 5 years. This study found no significant differences in tooth displacement comparing patients with and without pre‐implant orthodontic treatment. No significant effect of sex, age, orthodontic retention, or implant location was observed on tooth displacement.

SummaryAimsNeuroinflammation contributed to the pathogenesis of multiple system atrophy (MSA). We aimed to detect the correlation between inflammatory mediators, such as Klotho (Klt), vitamin D (25(OH)D) and homocysteine (Hcy), and disease severity among MSA patients.MethodsA total of 53 MSA patients, 65 PD patients, and 62 normal subjects were recruited in our cross‐sectional study. Serum Klotho (Klt), vitamin D (25(OH)D), and homocysteine (Hcy) levels were measured. Several scales were undertaken to assess the motor/nonmotor function and cognitive impairment of MSA.ResultsDecreased Serum Klt and 25(OH)D levels and increased Hcy levels were found in patients with MSA, compared with healthy controls. These results were more pronounced in male patients. The three biomarkers also displayed differences between MSA and PD subgroups based on genders. Interestingly, Klt, 25(OH)D and Hcy levels associated with cognition impairment, motor dysfunction, mood/cardiovascular disorder among MSA patients. In addition, the combination of Klt, 25(OH)D and Hcy had a better diagnostic ability for distinguishing MSA patients from healthy subjects, as well as distinguishing male MSA patients from male PD patients.ConclusionThis study suggested that Klt, 25(OH)D and Hcy levels could be a potential predictor for MSA severity evaluation.
Assessing prefrontal cortex oxygenation after sport concussion with near‐infrared spectroscopy
Authors: Bishop Scott A. , Neary J. Patrick 
Published: June 2017

SummaryBackgroundClinicians typically rely on neuropsychological and balance tests to track concussion recovery. The aforementioned tests imply impairments that are based on performance, but these tests do not directly measure brain physiology throughout concussion recovery. Because of these issues, an objective biomarker that can index severity and the recovery timeline is needed. Moreover, the number of concussions occurring at a recreational level requires the biomarker to be easily administered in a cost effective manner, and the results easily interpreted.MethodsTo address these issues, near‐infrared spectroscopy was used to assess the relative changes in oxy (HbO2)‐ and deoxyhaemoglobin and the associated standard deviations (SD) in the prefrontal cortex. Resting haemoglobin, and haemoglobin changes in response to hypercapnia (five repeated 20s breath holds), was measured in all participants. Data were aggregated into healthy baselines (n = 115), and concussed participants on days 1–3 (n = 14), 4–6 (n = 8), and 7–14 (n = 11). The data were statistically compared using a 1 × 4 ANOVA.ResultsResting HbO2 values progressively lowered from days 1–3 to 7–14 (with no differences compared to controls). The second major finding showed that hypercapnic HbO2 SD was significantly lower than resting values on days 1–3 and 4–6, but reversed back towards the healthy control group on day 7–14.ConclusionMonitoring cerebral oxygenation changes is a viable biomarker to assess the physiological state of the brain following concussion.
White Collar Crime In Museums
Authors: Cox Steven Peter 
Published: June 2017

AbstractWhite Collar Crime (WCC) can be defined as crimes committed by employees against their employers. Little empirical research has been conducted into WCC in the museum sector. The majority of a museums collection is held in back‐of‐house storage facilities with only a relatively small number of objects actually on public display. The true extent of WCC is unknown and it is a difficult area because of its complexity and invisibility. The article gives an overview of white‐collar crime, outlines the characteristics and techniques of this type of crime and seeks to identify the problems of controlling white‐collar crime with particular reference to the UK museum sector.

Published: June 2017

AbstractPublic procurement plays a key role both in the proper functioning of public administration and in the realization of broader policy objectives. This article aims to present a methodology to assess the Brazilian public procurement market based on government statistics, as well as reflect on the potential of public procurement policy for the development of the country. The article found that public procurement comprised an average of 13.8% of Brazil's gross domestic product during 2006−2012. The Brazilian public procurement market is comparable to that of a typical Organisation for Economic Co‐operation and Development (OECD) country. These findings imply great potential for public procurement in Brazil as a policy instrument for promoting the country's development.

Published: June 2017

BackgroundThe current subclassification of migraine is according to headache frequency and aura status. The variability in migraine symptoms, disease course, and response to treatment suggest the presence of additional heterogeneity or subclasses within migraine.ObjectiveThe study objective was to subclassify migraine via a data‐driven approach, identifying latent factors by jointly exploiting multiple sets of brain structural features obtained via magnetic resonance imaging (MRI).MethodsMigraineurs (n = 66) and healthy controls (n = 54) had brain MRI measurements of cortical thickness, cortical surface area, and volumes for 68 regions. A multimodality factor mixture model was used to subclassify MRIs and to determine the brain structural factors that most contributed to the subclassification. Clinical characteristics of subjects in each subgroup were compared.ResultsAutomated MRI classification divided the subjects into two subgroups. Migraineurs in subgroup #1 had more severe allodynia symptoms during migraines (6.1 ± 5.3 vs. 3.6 ± 3.2,P = .03), more years with migraine (19.2 ± 11.3 years vs 13 ± 8.3 years,P = .01), and higher Migraine Disability Assessment (MIDAS) scores (25 ± 22.9 vs 15.7 ± 12.2,P = .04). There were not differences in headache frequency or migraine aura status between the two subgroups.ConclusionsData‐driven subclassification of brain MRIs based upon structural measurements identified two subgroups. Amongst migraineurs, the subgroups differed in allodynia symptom severity, years with migraine, and migraine‐related disability. Since allodynia is associated with this imaging‐based subclassification of migraine and prior publications suggest that allodynia impacts migraine treatment response and disease prognosis, future migraine diagnostic criteria could consider allodynia when defining migraine subgroups.

Published: June 2017

AimTo evaluate the efficacy of the newly proposed albumin–bilirubin (ALBI) grade for therapy selection, clinical features of patients treated with radiofrequency ablation (RFA) were elucidated.MethodsFrom 2000 to 2015, 1101 patients with HCC (<3 cm, ≤3 tumors) treated with RFA were enrolled, with the following clinical features: 734 men and 367 women; 779 with hepatitis C virus, 153 with hepatitis B virus, 5 with hepatitis C and B, and 164 others; and Child–Pugh classification (CP) A : B ratio of 842:259. Liver damage classification (LD) using the indocyanine green retention rate at 15 min and ALBI‐grade were compared in regard to the prognoses of those patients.ResultsMedian tumor size was 1.7 cm (interquartile range, 1.4–2.2 cm) and single tumors were found in 802 cases (72.8%) (tumor–node–metastasis stage of the Liver Cancer Study Group of Japan I : II : III = 536:454:111). In the LD‐A group, the number of cases with ALBI‐grade 1, 2, and 3 were 294, 224, and 1, respectively, while those in the LD‐B group were 47, 490, and 12, respectively. In the LD‐C group, 19 and 14 patients were ALBI‐2 and ‐3, respectively. Akaike Information Criterion values for CP, LD‐grade, and ALBI‐grade were 6015.4, 5988.8, and 5990.7, respectively. However, there was no significant difference regarding prognosis between LD‐A/B (n = 228) and C (n = 31) (median survival time, 4.8 vs. 3.9 years, P = 0.0818) in CP‐B, whereas a significant difference was observed regarding prognosis for ALBI‐1/2 (n = 232) and ALBI‐3 (n = 27) (median survival time, 4.8 vs. 2.7 years, P = 0.0168).ConclusionAlbumin–bilirubin grade showed an assessment ability similar to that of LD‐grade. Furthermore, there was a small improvement in prognosis following RFA in patients with an ALBI‐grade of 3. Although only two serological parameters, albumin and total bilirubin, are used, assessment with ALBI‐grade may be more useful than with LD‐grade for avoiding a non‐beneficial RFA procedure.
Poly(methacrylate)‐derived diblock dispersant for TiO2 in aqueous suspensions

Published: June 2017

AbstractIn this paper, we propose a newly designed dispersant, ammonium poly(methacrylate)‐block‐poly(2‐phenoxyethyl acrylate) (PMA‐b‐PBEA), and our rheological and zeta potential test results verify its superior dispersion efficiency for aqueous suspensions in comparison to the commercial dispersant ammonium polyacrylate (PAA‐NH4). The extremely high dispersion efficiency of PMA‐b‐PBEA correlates closely to its diblock structure, which simultaneously exhibits a less polar anchoring head group and a water‐dissociable stabilizing moiety. The unique structure of PMA‐b‐PBEA accounts for its high powder adsorption effectiveness, which is demonstrated in its adsorption capability being double that of PAA‐NH4.

AbstractAimTo test competing hypotheses about the timing and extent of Holocene landscape opening using pollen‐based quantitative land‐cover estimates.LocationDove Lake, Tasmanian Wilderness World Heritage Area, Australia.MethodsFossil pollen data were incorporated into pollen dispersal models and corrected for differences in pollen productivity among key plant taxa. Mechanistic models (REVEALS—Regional Estimates of VEgetation Abundance from Large Sites) employing different models for pollen dispersal (Gaussian plume and Lagrangian stochastic models) were evaluated and applied in the Southern Hemisphere for the first time.ResultsValidation of the REVEALS model with vegetation cover data suggests an overall better performance of the Lagrangian stochastic model. Regional land‐cover estimates for forest and non‐forest plant taxa show persistent landscape openness throughout the Holocene (average landscape openness ~50%). Gymnoschoenus sphaerocephalus, an indicator of moorland vegetation, shows higher values during the early Holocene (11.7–9 ka) and declines slightly through the mid‐Holocene (9–4.5 ka) during a phase of partial landscape afforestation. Rain forest cover reduced (from ~40% to ~20%) during the period between 4.2–3.5 ka.Main conclusionsPollen percentages severely under‐represent landscape openness in western Tasmania and this bias has fostered an over‐estimation of Holocene forest cover from pollen data. Treeless vegetation dominated Holocene landscapes of the Dove Lake area, allowing us to reject models of landscape evolution that invoke late‐Holocene replacement of a rain forest‐dominated landscape by moorland. Instead, we confirm a model of Late Pleistocene inheritance of open vegetation. Rapid forest decline occurred after c. 4 ka, likely in response to regional moisture decline.

AbstractBackgroundContact allergy is a common condition and can severely interfere with daily life or professional activities. Due to changes in exposures, such as introduction of new substances, new products or formulations and regulatory intervention, the spectrum of contact sensitization changes.ObjectiveTo evaluate the current spectrum of contact allergy to allergens present in the European baseline series (EBS) across Europe.MethodsRetrospective analysis of data collected by the European Surveillance System on Contact Allergies (ESSCA,www.essca-dc.org) in consecutively patch‐tested patients, 2013/14, in 46 departments in 12 European countries.ResultsAltogether, 31 689 patients were included in the analysis. Compared to a similar analysis in 2004, the prevalence of contact allergy to methylisothiazolinone went up to around 20% in several departments. In comparison, contact allergy to the metals nickel, cobalt and chromium remained largely stable, at 18.1%, 5.9% and 3.2%, respectively, similar to mostly unchanged prevalence with fragrance mix I,IIandMyroxylon pereirae(balsam of Peru) at 7.3%, 3.8% and 5.3%, respectively. In the subgroup of departments diagnosing (mainly) patients with occupational contact dermatitis, the prevalence of work‐related contact allergies such as epoxy resin or rubber additives was found to be increased, compared to general dermatology departments.ConclusionContinuous surveillance of contact allergy based on network data offers the identification of time trends or persisting problems, and thus enables focussing in‐depth research (subgroup analyses, exposure analysis) on areas where it is needed.
