ObjectiveSocial comparisons (ie, self-evaluation in comparison with others) influence patients’ perspectives of their disease and may impact motivation and health behavior; however, little is known about patients’ perspectives toward receiving such information in a clinical context (eg, from their doctor’s office or health system). This study aims to understand patients’ perspectives and anticipated responses to receiving social comparison information regarding measures of their diabetes-related health status (eg, A1C) and how receiving such information would compare with goal-based comparisons (ie, self-evaluation in comparison with goal).Research design and methodsWe conducted semistructured interviews with 25 patients with type 2 diabetes mellitus (T2DM) regarding social and goal-based comparisons involving their diabetes health status and qualitatively analyzed interviews for themes.ResultsWe identified seven major themes: self-relevance, motivation, self-concept, emotions, information seeking, medical care, and self-care. Participants commonly anticipated increased motivation and improved health behaviors in response to both social and goal-based comparisons. Subthemes unique to social comparisons included belief that this information would be motivating by engaging some patients’ competitiveness, perception that this information was more ‘personalized’ than comparisons with a standard goal (eg, A1C<7), and desire to learn from individuals similar to oneself who were doing better.ConclusionsOur findings provide significant insights into the anticipated response of patients with T2DM to receiving social and goal-based comparison information regarding their diabetes health status. Providing patients with diabetes with social and goal-based comparison information may affect motivation, mood, and self-concept in ways that may improve or sustain diabetes self-care behaviors for some patients.

ObjectiveThe Japan Acuity and Triage Scale (JTAS) was developed based on Canadian Triage and Acuity Scale in 2012 and has been implemented in many Japanese EDs. We assessed the validity of JTAS by examining the association between JTAS triage levels and throughput and clinical outcomes in adult patients.MethodsWe conducted a retrospective analysis of prospectively collected clinical data in the ED of a Japanese tertiary-care hospital. We included self-presenting patients who were ≥16 years of age and triaged between June 2013 and May 2014. We assessed the association between the triage level and overall admission and admission to the intensive care units (ICUs) with multivariable logistic regression analysis adjusted with patients’ age and the time of visit and ED length of stay using the Kruskal-Wallis rank-sum test. We examined the predictive ability of JTAS for determining overall and ICU admission using receiver operating characteristic curves.ResultsWe included a total of 27 120 adult patients in our study. The OR for overall admission was greater with a higher triage level compared with the lowest urgency levels. ED length of stay was significantly longer with a higher JTAS level (p<0.001). The OR for ICU admission was greater in JTAS 1 (117.93 (95% CI 69.07 to 201.38)) and JTAS 2 (9.43 (95% CI 13.74 to 29.30)) compared with the lowest urgency levels. The areas under the curve for the predictive ability of JTAS for overall and ICU admission were 0.726 and 0.792, respectively.ConclusionOur study suggests an association of JTAS acuity with overall admission, ICU admission and ED length of stay, thereby demonstrating the predictive validity of JTAS.

Published: May 2018

ObjectiveIntestinal inflammation has been suggested to play a role in development of Parkinson’s disease (PD) and multiple system atrophy (MSA). To test the hypothesis that IBD is associated with risk of PD and MSA, we performed a nationwide population-based cohort study.DesignThe cohort consisted of all individuals diagnosed with IBD in Denmark during 1977–2014 (n=76 477) and non-IBD individuals from the general population, who were comparable in terms of gender, age and vital status (n=7 548 259). All cohort members were followed from IBD diagnosis/index date to occurrence of PD and MSA (according to the Danish National Patient Register).ResultsPatients with IBD had a 22% increased risk of PD as compared with non-IBD individuals (HR=1.22; 95% CI 1.09 to 1.35). The increased risk was present independently of age at IBD diagnosis, gender or length of follow-up. The overall incidence of MSA was low in our study, and the regression analysis suggested a tendency towards higher risk of developing MSA in patients with IBD as compared with non-IBD individuals (HR=1.41; 95% CI 0.82 to 2.44). Estimates were similar for women and men. The increased risk of parkinsonism was significantly higher among patients with UC (HR=1.35; 95% CI 1.20 to 1.52) and not significantly different among patients with Crohn’s disease (HR=1.12; 95% CI 0.89 to 1.40).ConclusionsThis nationwide, unselected, cohort study shows a significant association between IBD and later occurrence of PD, which is consistent with recent basic scientific findings of a potential role of GI inflammation in development of parkinsonian disorders.

Published: May 2018

ObjectiveTo investigate the associations between using alternatives to the car which are more active for commuting and non-commuting purposes, and morbidity and mortality.MethodsWe conducted a prospective study using data from 3 58 799 participants, aged 37–73 years, from UK Biobank. Commute and non-commute travel were assessed at baseline in 2006–2010. We classified participants according to whether they relied exclusively on the car or used alternative modes of transport that were more active at least some of the time. The main outcome measures were incident cardiovascular disease (CVD) and cancer, and CVD, cancer and all-cause mortality. We excluded events in the first 2 years and conducted analyses separately for those who regularly commuted and those who did not.ResultsIn maximally adjusted models, regular commuters with more active patterns of travel on the commute had a lower risk of incident (HR 0.89, 95% CI 0.79 to 1.00) and fatal (HR 0.70, 95% CI 0.51 to 0.95) CVD. Those regular commuters who also had more active patterns of non-commute travel had an even lower risk of fatal CVD (HR 0.57, 95% CI 0.39 to 0.85). Among those who were not regular commuters, more active patterns of travel were associated with a lower risk of all-cause mortality (HR 0.92, 95% CI 0.86 to 0.99).ConclusionsMore active patterns of travel were associated with a reduced risk of incident and fatal CVD and all-cause mortality in adults. This is an important message for clinicians advising people about how to be physically active and reduce their risk of disease.
Lessons identified from the 2017 Manchester and London terrorism incidents. Part two: the reception and definitive care (hospital) phases
Authors: Hunt Paul 
Published: May 2018

The provision of medical care during the reception and definitive care phases of a terrorist incident will likely take place in designated receiving hospitals such as Major Trauma Centres. There is a need for an enhanced capability in such units to receive, initially manage and hold casualties with more serious injuries. Also, even less severely injured casualties may require significant time and clinical input such as risk management in potential bloodborne viruses.The distribution of casualties from the incident scene requires advance consideration of the injury pattern and regional network organisation of specialist services, such as maxillofacial, neurosurgery or severe burns care. Paediatric centres are also more sparsely distributed and often only in large city networks which represents a significant challenge for planners and responders in other regions. An effective response relies on a coordinated multidisciplinary approach including emergency and front-of-house teams, surgical, medical and clinical support services.

Published: May 2018

ObjectivesImaging studies in patients with cutaneous psoriasis have demonstrated asymptomatic bone and tendon changes, commonly of the foot and ankle. We sought to determine if patients with cutaneous psoriasis have an increased risk of clinically significant foot and ankle tendinopathy or enthesopathy compared with the general population.MethodsPatients with cutaneous psoriasis and a general population cohort were identified in The Health Improvement Network, a general practice medical records database from the UK. All patients with psoriatic arthritis were excluded. Cox proportional-hazards models (α=0.05) estimated the HR for development of foot and ankle tendinopathy or enthesopathy among patients with psoriasis, with adjustment for numerous covariates.ResultsIn total, 78 630 patients with cutaneous psoriasis and 5 983 338 persons from the general population were identified. In an unadjusted model, patients with cutaneous psoriasis had a 25% increased risk of developing foot and ankle tendinopathy or enthesopathy compared with the general population (HR 1.25, 95% CI 1.20 to 1.30, p<0.0001). The HR remained unchanged and statistically significant after adjusting for covariates, and in sensitivity analyses.ConclusionsThese data suggest that patients with psoriasis can have foot and ankle tendinopathy or enthesopathy without having psoriatic arthritis, presenting a diagnostic challenge to physicians. Further research is needed to elucidate mechanisms contributing to this increased risk.

BiPb-2212 phase in nanoscale was added to BiPb-2223 phase with a general stoichiometry of (Bi[Formula: see text]Pb[Formula: see text]Sr[Formula: see text]Ca[Formula: see text]Cu[Formula: see text]O[Formula: see text]/Bi[Formula: see text]Pb[Formula: see text]Sr[Formula: see text]Ca[Formula: see text]Cu[Formula: see text]O[Formula: see text], 0.0 [Formula: see text] x [Formula: see text] 2.5 wt.%. All samples were prepared by the standard solid-state reaction method. The prepared nano BiPb-2212 phase was characterized by X-ray powder diffraction (XRD) and transmission electron microscope (TEM). The prepared samples were characterized by XRD and the scanning electron microscope (SEM). XRD analysis indicated that the sample with x = 1.5 wt.% has the highest relative volume fraction for BiPb-2223 phase. Samples were examined by electrical resistivity and I–V measurements. There is no significant change in the superconducting transition temperature [Formula: see text] for all samples. The highest critical current density [Formula: see text] was recorded for the sample with x = 1.5 wt.%. The normalized excess conductivity [Formula: see text] was calculated according to Aslamazov–Larkin (AL) model. Four different fluctuating regions were recorded as the temperature decreased. The coherence length along the c-axis at 0 K [Formula: see text], interlayer coupling strength s, Fermi velocity [Formula: see text] of the carriers and Fermi energy [Formula: see text] were calculated for both samples with x = 0.0 wt.% and 1.5 wt.%.
Electronic theoretical study on the influence of torsional deformation on the electronic structure and optical properties of BN-doped graphene
Authors: Fan Dazhi , Liu Guili , Wei Lin 
Published: May 2018

Based on the density functional theory, the effect of torsional deformation on the electronic structure and optical properties of boron nitride (BN)-doped graphene is studied by using the first-principles calculations. The band structure calculations show that the intrinsic graphene is a semi-metallic material with zero band gap and the torsional deformation has a large effect on its band gap, opening its band gap and turning it from the semi-metal to the medium band gap semiconductor. The doping of BN in graphene makes its band gap open and becomes a medium band gap semiconductor. When it is subjected to a torsional effect, it is found to have a weak influence on its band gap. In other words, the doping of BN makes the changes of the band gap of graphene no longer sensitive to torsional deformation. Optical properties show that the doping of BN leads to a significant decrease in the light absorption coefficient and reflectivity of the graphene at the characteristic peak and that of BN-doped graphene system is also weakened by torsional deformation at the characteristic peak. In the absorption spectrum, the absorption peaks of the doping system of the torsion angle of 2–20[Formula: see text] are redshifted compared with that of the BN-doped system (the torsion angle is 0[Formula: see text]). In the reflection spectrum, the two reflection peaks are all redshifted relative to that of the BN-doped system (the torsion angle is 0[Formula: see text]) and when the torsion angle exceeds 12[Formula: see text], the size relationship between the two peaks is interchanged. The results of this paper are of guiding significance for the study of graphene-based nanotube devices in terms of deformation.
Metamorphic fluid superimposition of the Changba–Lijiagou Pb–Zn deposit, West Qinling Orogen, central China
Authors: Ni Pei , Wang Tian-Gang , Wang Guo-Guang , Li Wen-Sheng , Pan Jun-Yi 
Published: May 2018

Abstract

Several large to giant Pb–Zn deposits in the West Qinling Orogen in central China are argued to be of SEDEX (sedimentary exhalative) type or of epigenetic hydrothermal type. Additionally, the nature of the mineralizing fluids is poorly known. Our observations suggest that early stage primary marine sedimentary mineralization is characterized by laminated or disseminated fine-grained massive sulphide ores, and late stage metamorphic superimposition is represented by coarser equigranular annealed textures and the disruption of thinly laminated structures. Three coexisting types of fluid inclusions were recognized: H
2
O–NaCl (type I); H
2
O–NaCl–CH
4
–CO
2
(type II); and CH
4
–CO
2
(type III). The coexisting type I and II inclusions show similar homogenization temperature values but different salinities, indicating that fluid immiscibility occurred. Formation pressures calculated using type III inclusions are high (72.5–174.5 MPa). The lead isotopes of the sulphides and calcites show a narrow range. The primary sedimentary ore textures plus the similar lead isotopes between the ores and the wall rocks suggest a SEDEX origin, but the annealed recrystallization textures, the immiscible carbonic fluid inclusion assemblages and higher formation pressures suggest a strong late-stage metamorphic superimposition on the original SEDEX-type ores.
Mass-transfer and differential element mobility in metapelites during multistage metamorphism of the Yenisey Ridge, Siberia
Authors: Likhanov I. I. 
Published: May 2018

Abstract

Pelitic gneisses and schists from the Garevka Complex (Yenisey Ridge) at the western margin of the Siberian craton contain zoned garnet porphyroblasts that show clear evidence of multistage growth. The three discrete stages define a counter-clockwise pressure–temperature (
P–T
) path involving initial prograde low pressure heating followed by near-isothermal medium-pressure compression and post-peak retrograde synexhumation decompression and cooling. The combined study of the variations of
in-situ
major and trace element mineral compositions of coexisting minerals and mineral modes with changing
P
and
T
conditions and metamorphic reactions in rocks allowed detailed investigation of metamorphic processes. A significant increase in pressure during prograde collision-related metamorphism correlates with an abrupt increase of Ca in garnets, which in turn is accompanied by a significant decrease in heavy rare earth elements (HREE) and Y contents. Decrease in temperature and pressure during retrograde metamorphism led to an increase in the HREE and Y content in garnets with concomitant decrease of grossular component of garnet. A pronounced systematic negative correlation between HREE including Y content and Ca content in garnet can be attributed to substitution of trivalent rare earth elements (REE) and Y for divalent Ca cations on eightfold sites. The main reasons for the sharp increase in Ca content in garnets during collisional metamorphism are either (1) the redistribution between garnet and plagioclase, which led to less calcium in composition, or (2) consequence of epidote breakdown. A mass balance of major and trace elements between the reactants and products of metamorphic reactions yield very good matches between the measured and reconstructed modal abundances in all cases, indicating that collisional metamorphism was essentially isochemical with respect to most elements, with the exception of HREE. The minimum equilibration volume for the major elements was
c.
1 mm
3
. The total HREE balance requires a rather greater reaction volume involved in the redistribution of HREEs, of the order of 3–8 mm
3
which provides evidence for their relatively higher migration mobility during metamorphism in comparison with other REE.
The granulite- to eclogite- and amphibolite-facies transition: a volume and mass transfer study in the Lindås Nappe, Bergen Arcs, west Norway
Authors: Centrella Stephen 
Published: May 2018

Abstract

This study is focused on a specific outcrop in the Bergen Arcs, Norway where the transition between dry granulite and the hydrated eclogite and amphibolite is exposed. In this outcrop the foliation in the granulite is continuous as it passes through eclogite- and amphibolite-facies rocks, presenting a challenge to understanding the nature of these spatial relationships. Although there is no major change in the bulk chemical composition of all three metamorphic-facies rocks, the loss of ignition (LOI) content increases from granulite to the eclogite and to the amphibolite. During hydration and metamorphism, the density changes from
c.
3 g cm
−3
for the anorthositic granulite to 3.2 g cm
−3
for the eclogite, and 2.75 g cm
−3
for the amphibolite. Based on the mass balance equation, eclogitization of the granulite shows a reduction of volume of
c.
3% whereas amphibolitization of the granulite gains
c.
5% in volume. By assuming equilibrium, modelling the phase equilibria provides estimates of the amount of fluid necessary to form the eclogite and the amphibolite assemblages. Results show that both assemblages can be stable at similar temperature and a similar fluid composition but differ in pressure by
c.
10 kbar. This study suggests that the stress generated during hydration of the granulite may influence the local mineral assemblage equilibrium.
Typology of hard rock ground waters within the Lower Sassandra, a main catchment in humid tropical West Africa

Published: May 2018

Abstract
Randomness of fracture networks still makes channelized flow a challenge to track in hard-rock aquifers. While not underestimating geological and hydrological criteria that are also handled here through mapping exercises, this study raises an issue of water quality encountered in lifelong boreholes. Chemical classification checked against a recent conceptual model of bedrock aquifers gives birth to a new typology of groundwater in a complex granitic aquifer system located in the SW of Ivory Coast (West Africa). Major ion chemistry, borehole completion data, digital elevation model and satellite images are used to interpret the geochemical water facies as an expression of connexions between the saprolite and the saprock, or transient insulation. From major ions ratios, cumulate mineralization, carbonate equilibrium, stable isotopes, the maturation of ground waters and mixing between bedrock layers are described at seasonal and local scales. The results highlight some vertical feeding of the water table into the main saprock aquifer owing to shortcuts through the saprolite, along with the existence of dead-ends in the hydraulically active fracture network. Also, some influence of fault zones, either drain or barrier, is confirmed on the (Ca, Mg) bicarbonate water facies within the saprock.
Geikie's science in the cemetery
Authors: Morgan Nina 
Published: May 2018

Abstract
Natural stone is an important material used for buildings, walls and monuments. However, when used outdoors, it is subject to damage by the effects of weathering. Inspired by the experiments carried out by Friedrich Pfaff, a German geologist and professor of mineralogy at the University of Erlangen, Germany, in the 1870s, Archibald Geikie became interested in the subject of rock weathering and came up with the idea of using gravestones as a means of monitoring weathering in stone used for building. This work, apparently carried out in cemeteries in Edinburgh as a sideline to his normal fieldwork activities, was described in 1880 in a communication read to the Royal Society of Edinburgh. It represents the first comprehensive scientific study of rock weathering published in English, and the methodology Geikie developed for his study formed the basis for modern studies of rock weathering using gravestones.
