AbstractBackgroundPain is prevalent in chronic obstructive pulmonary disease (COPD) and the Brief Pain Inventory (BPI) appears to be a feasible questionnaire to assess this symptom. However, the reliability and validity of the BPI have not been determined in individuals with COPD. This study aimed to determine the internal consistency, test–retest reliability and validity (construct, convergent, divergent and discriminant) of the BPI in individuals with COPD.MethodsIn order to examine the test–retest reliability, individuals with COPD were recruited from pulmonary rehabilitation programmes to complete the BPI twice 1 week apart. In order to investigate validity, de‐identified data was retrieved from two previous studies, including forced expiratory volume in 1‐s, age, sex and data from four questionnaires: the BPI, short‐form McGill Pain Questionnaire (SF‐MPQ), 36‐Item Short Form Survey (SF‐36) and Community Health Activities Model Program for Seniors (CHAMPS) questionnaire.ResultsIn total, 123 participants were included in the analyses (eligible data were retrieved from 86 participants and additional 37 participants were recruited). The BPI demonstrated excellent internal consistency and test–retest reliability. It also showed convergent validity with the SF‐MPQ and divergent validity with the SF‐36. The factor analysis yielded two factors of the BPI, which demonstrated that the two domains of the BPI measure the intended constructs. The BPI can also discriminate pain levels among COPD patients with varied levels of quality of life (SF‐36) and physical activity (CHAMPS).ConclusionThe BPI is a reliable and valid pain questionnaire that can be used to evaluate pain in COPD.SignificanceThis study formally established the reliability and validity of the BPI in individuals with COPD, which have not been determined in this patient group. The results of this study provide strong evidence that assessment results from this pain questionnaire are reliable and valid.

AbstractPlanar solid oxide fuel cells (SOFC) with CuO/gadolinium‐doped ceria (GDC) supporting anode were produced and tested in H2 and in CH4/CO2 mixture at 650 °C. The electrolyte densification at 900 °C was promoted by compressive strains induced by larger anodic thickness. The reduction behaviour of CuO/GDC anodic powders was preliminarily evaluated. The electrochemical measurements showed an increasing power density with the anode thickness (from ≈500 μm to ≈1.4 mm) reaching a maximum value of 227 mW cm−2 at 650 °C in pure H2. Power density of 29 mW cm−2 was measured in wet CH4/CO2 biogas mixture at 650 °C. Catalytic activity measurements towards methane dry reforming showed limited conversion at all investigated temperatures, this suggesting that the actual anodic reaction is the methane combustion. Scanning electron microscope observations and energy dispersive X‐ray analyses of the cell tested in CH4/CO2 mixture did not show any carbon deposit, thus pointing out that the Cu/GDC cermet can be considered a stable and reliable anodic substrate for IT‐SOFC fed by CH4/CO2 mixture.

AbstractMartensitic transformations of rapidly quenched and less‐rapidly cooled Heusler alloys of type Ni–Mn–X with X=Ga, In, and Sn are investigated by ab initio calculations. For alloys rapidly cooled from 1173 K, we obtain the well‐known magnetocaloric properties near the magnetocaloric phase transition. For the less‐rapidly cooled alloys with secondary heat treatment these magnetocaloric properties start to change considerably, because each alloy transforms during temper‐annealing into a dual‐phase composite alloy. These two phases are identified to be cubic stoichiometric Ni2MnX and tetragonal disordered NiMn.

AbstractPersonality features are considered to be important factors in the pathogenesis of both eating disorder (ED) and substance use disorder (SUD). This study investigates similarities and differences between these early maladaptive schemas (EMSs) (a) between female patients with ED (N = 179) or SUD (N = 169) and (b) between ED subtypes of the restrictive (N = 52), bulimic type (N = 127), or SUD. In total, 348 female patients (Mage = 29.95; SDage = 8.40) completed the Young Schema Questionnaire. Multivariate analyses of covariance with EMS scales as dependent variables and (a) ED versus SUD and (b) ED subtypes versus SUD as independent variables and age and psychopathology as control variables revealed that ED patients scored significantly higher on Unrelenting Standards, Defectiveness, Social Undesirability, and Failure than did SUD patients. Additionally, when comparing ED subtypes and SUD, bulimic and SUD patients scored significantly higher on Insufficient Self‐Control than did restrictive patients. These results confirm the role of EMSs in ED (subtypes) and SUD.
Geochemistry of the Zhibo submarine intermediate‐mafic volcanic rocks and associated iron ores, Western Tianshan, Northwest China: Implications for ore genesis

Published: June 2018

The Zhibo iron deposit is hosted in Carboniferous submarine volcanic rocks in Western Tianshan, NW China. A series of magnetite‐bearing intermediate‐mafic volcanic rocks are recognized in the periphery of the Zhibo ore district. Most of these volcanic rocks formed at 314 ± 2 Ma, possess tholeiitic–calc‐alkaline affinities, and display remarkable negative Nb, Ta, and Ti anomalies on primitive mantle‐normalized incompatible element diagrams. These features, together with those of their relatively complete rock assemblages and Th/Yb versus Nb/Yb diagrams, are indicative of their formation in an active continental margin arc setting. The wide compositional spectrum of SiO2 values ranging from 47.11 to 62.75 wt.% and lower Mg# values (55–63) of basalts suggest that the Zhibo intermediate‐mafic volcanic rocks may have experienced magmatic differentiation. Their (Th/Ta)PM > 1, (La/Nb)PM > 1, Nb/Ta (11‐16), and Th/Ce (0.06‐0.23) values suggest that the source of these intermediate‐mafic volcanic rocks was significantly contaminated by crustal materials. The magnetites in the iron ore have lower contents of Al, Mn, Ti, and V, indicating that the mineralization of magnetite in the iron ore occurred under lower temperature and higher oxygen fugacity conditions than those in the intermediate‐mafic volcanic rocks. In addition, the magnetites in the Zhibo iron ores have lower contents of compatible elements (e.g., Ti, V, Mn, Co, Cr, and Zn) than those of the magnetite in the intermediate‐mafic volcanic rocks, suggesting that the Zhibo magnetites crystallized from late‐stage, residual iron‐rich magmatic melts/magmatic‐hydrothermal fluids. In addition, the textures of the volcanic rocks suggest that iron have ever enriched in the residual melt during the magmatic stage, and the iron‐rich fragments in andesitic volcaniclastic rocks indicate that the ore‐forming material was a high‐salinity fluid‐bearing iron‐rich melt. In combination of available information, including field observations and geochemical analyses, we interpret that the Zhibo iron deposit is magmatic‐hydrothermal in origin.

AbstractThe outcome of patients with relapsed/refractory classical Hodgkin lymphoma (R/R cHL) after autologous stem cell transplantation (auto‐SCT) is poor. Recently, the anti‐CD30 monoclonal antibody‐drug conjugate, brentuximab vedotin (BV), has shown remarkable activity in the setting of R/R cHL. In the pivotal phase II study, BV produced an overall response rate of 75% and a median progression‐free survival of 6.7 months. Although these results have been reproduced by large registry studies, the impact of BV on the overall survival (OS) of patients with R/R cHL has not been addressed so far. The aim of this study was to examine the impact of BV on OS in the setting of post auto‐SCT R/R cHL. Analysis was performed in a group of patients with R/R cHL after a previous auto‐SCT reported in the Greek registry during the last 2 decades. By using a multivariate model and censoring patients at the time of subsequent allo‐SCT or treatment with immune checkpoint inhibitors, we showed that treatment with BV in the posttransplant relapse setting has a positive impact on the outcome and results in significant improvement of OS. To our knowledge, this the first published study, addressing the impact of BV on the OS in the setting of posttransplant relapse.
Front Cover: Analysis of basidiomycete pigments in situ by Raman spectroscopy (J. Biophotonics 6/2018)

Published: June 2018

Basidiomycetes, i.e., mushroom‐type fungi, are known to produce pigments with a high level of unsaturation. These compounds can neutralize highly oxidative species in the event of close contact with other microbes. The identification of these pigments is important to understand the defense mechanism of fungi, which is essential to counteract an uncontrolled spread of harmful species. Here, we introduce a possibility to non‐invasively investigate the pigmentation by Raman spectroscopy.Further details can be found in the article by James Tauber et al. (e201700369).

Published: June 2018

AbstractIntroductionWeaknesses in care programmes providing anti‐retroviral therapy (ART) persist and are often instigated by late HIV diagnosis and poor linkage to care. We investigated the potential for a home‐based counselling and testing (HBCT) campaign to be improved through the optimal timing and enhancement of testing rounds to generate greater health outcomes at minimum cost.MethodsUsing a mathematical model of HIV care calibrated to longitudinal data from The Academic Model Providing Access To Healthcare (AMPATH) in Kenya, we simulated HBCT campaigns between 2016 and 2036, assessing the impact and total cost of care for each, for a further 20 years.ResultsWe find that simulating five equally spaced rounds averts 1.53 million disability‐adjusted life‐years (DALYs) at a cost of $1617 million. By altering the timing of HBCT rounds, a four‐round campaign can produce greater impact for lower cost. With “front‐loaded” rounds, the cost per DALY averted is reduced by 12% as fewer rounds are required ($937 vs. $1060). Furthermore, improvements to HBCT coverage and linkage to care avert over two million DALYs at a cost per DALY averted of $621 (41% less than the reference scenario).ConclusionsCountries implementing HBCT can reduce costs by optimally timing rounds and generate greater health outcomes through improving linkage, coverage, and retention. Tailoring HBCT campaigns to individual settings can enhance patient outcomes for minimal cost.

Abstract
It has been well established that patients with diabetes or metabolic syndrome (MetS) have increased prevalence and severity of periodontitis, an oral infection initiated by bacteria and characterized by tissue inflammation and destruction. To understand the underlying mechanisms, we have shown that saturated fatty acid (SFA), which is increased in patients with type 2 diabetes or MetS, and LPS, an important pathogenic factor for periodontitis, synergistically stimulate expression of proinflammatory cytokines in macrophages by increasing ceramide production. However, the mechanisms by which increased ceramide enhances proinflammatory cytokine expression have not been well understood. Since sphingosine 1 phosphate (S1P) is a metabolite of ceramide and a bioactive lipid, we tested our hypothesis that stimulation of ceramide production by LPS and SFA facilitates S1P production, which contributes to proinflammatory cytokine expression. Results showed that LPS and palmitate, a major SFA, synergistically increased not only ceramide, but also S1P, and stimulated sphingosine kinase (SK) expression and membrane translocation in RAW264.7 macrophages. Results also showed that SK inhibition attenuated the stimulatory effect of LPS and palmitate on IL-6 secretion. Moreover, results showed that S1P enhanced the stimulatory effect of LPS and palmitate on IL-6 secretion. Finally, results showed that targeting S1P receptors using either S1P receptor antagonists or small interfering RNA attenuated IL-6 upregulation by LPS and palmitate. Taken together, this study demonstrated that LPS and palmitate synergistically stimulated S1P production and S1P in turn contributed to the upregulation of proinflammatory cytokine expression in macrophages by LPS and palmitate.
LPS and palmitate synergistically increase S1P and, in turn, S1P contributes to upregulation of proinflammatory genes by LPS and palmitate.
Reflection in the heat of the moment: The role of in‐action team reflexivity in health care emergency teams
Authors: Schmutz Jan B. , Lei Zhike , Eppich Walter J. , Manser Tanja 
Published: June 2018

SummaryTeam reflexivity (TR)–defined as a team's conscious reflection on their objectives, strategies, and processes—is an important team process that fosters adaptation and information processing. However, traditional conceptualizations frame TR as a process that occurs in periods of downtime to reflect on past, terminated performance, largely ignoring reflective team processes occurring during intense performance events of action teams. To address this gap, we conceptualize TR as a team process that occurs not only during periods of downtime after the action but alsoduringperformance events as brief TR moments. We elaborate on the concept of in‐action TR and explore it by delineating its relationship to task type and timing during a performance event. Further, we test a team level contingency model of in‐action TR, namely, team size and performance. Using behavior observation, we test our hypothesis with 70 medical teams responding to simulated in‐hospital emergencies. Task type is related to in‐action TR and reflection tends to increase as action progresses. Further, in‐action TR is related to team performance and is especially important for larger teams. Our study is the first to investigate in‐action TR and provides theoretical and practical implications on how in‐action TR operates in extreme action teams.
Linking Proactive Personality to Creative Performance: The Role of Job Crafting and High‐Involvement Work Systems
Authors: Li Hui , Jin Hui , Chen Tongyang 
Published: June 2018

AbstractThis study proposed that job crafting serves as a mechanism reflecting how proactive personality affects creative performance, and this study explored whether these relationships are moderated by high‐involvement work systems. Drawn from the conservation of resources theory to develop a cross‐level moderated mediation model, a three‐wave longitudinal study was conducted with 346 employees and their supervisors in 27 high technology firms in China. This study found that proactive personality was positively related to creative performance and that job crafting mediated the relationship between proactive personality and creative performance, and an indirect effect of proactive personality on creative performance through job crafting was significant when high‐involvement work systems was low but not high. Thus, the research results indicate that when human resource management involves less participatory management, incentive rewards, extensive training and information sharing, proactive employees can draw from their personality to craft their job tasks, relations and cognitions, thereby improving creative performance. The theoretical and managerial implications, limitations, and future research directions are discussed.

ABSTRACTBACKGROUNDDietary supplementation of sheep with bioactive compounds such as citrus flavonoids appears as a great alternative for improving meat antioxidant capacity and could also have beneficial effects on growth performance, carcass traits and meat quality characteristics. An experiment was therefore conducted to examine the effects of hesperidin or naringin dietary supplementation on lambs' growth performance, antioxidant status and meat quality characteristics. Forty‐four male 3‐month‐old Chios lambs were randomly assigned to four groups: C, fed with a basal diet, or H or N or VE offered the same diet further supplemented with hesperidin at 2500 mg or naringin at 2500 mg or α‐tocopheryl acetate (vitamin E) at 200 mg kg−1 feed respectively. At the end of the experiment (day 35), samples of longissimus thoracis muscle were collected for meat quality evaluation.RESULTSBoth flavonoids and vitamin E dietary supplementation reduced plasma malondialdehyde (MDA) levels on day 35 (P < 0.05). No significant differences were observed in performance traits and meat quality characteristics among the experimental groups (P > 0.05). Hesperidin and naringin also reduced MDA levels in meat stored at 4 °C for up to 8 days (P < 0.05), although to a lesser extent than α‐tocopheryl acetate.CONCLUSIONIncorporation of flavonoids in sheep diets resulted in an improvement of plasma and meat antioxidant capacity. © 2018 Society of Chemical Industry
Comparison of different applications of automatic herd control systems on dairy farms – a review
Authors: Grodkowski Grzegorz , Sakowski Tomasz , Puppel Kamila , Baars Ton 
Published: June 2018

ABSTRACTRecent years have seen the rapid development of different devices which can be helpful in the daily work of livestock farmers. The growing size of livestock herds has led farmers to lose individual contact with their animals, while behavioral studies show that breeders can effectively and precisely monitor a herd of up to 100 cows. This was the main motivation for this study, which aims to identify and test various electronic devices which provide useful herd management data, including estrus detection, individual activity and body temperature measurement, monitoring rumen pH levels, milk quality and content as well as milk temperature and somatic cell count measurements. Some devices can detect the metabolic status of animals with a reasonable level of precision. Contemporary animal farms are offered a large number of systems for monitoring the behavior of the animals in the herd and helping to identify those that are intended for insemination or are too active or excessively apathetic. Monitoring devices support herd management and help to reduce costs through the early detection of animal diseases and nutritional problems. This review aims to compile and summarize the information currently available on the use of automatic herd control systems on dairy farms, as well as to discuss the interpretation of the results, providing a useful diagnostic tool in nutritional evaluations of dairy herds. © 2018 Society of Chemical Industry
Foliar antitranspirant and soil superabsorbent hydrogel affect photosynthetic gas exchange and water use efficiency of maize grown under low rainfall conditions

Published: June 2018

AbstractBACKGROUNDTwo lysimeter experiments with maize plants were conducted to investigate the effect of combined superabsorbent polymer (SAP) and fulvic acid (FA) application on photosynthetic gas exchange and water use efficiency (WUE) under deficit irrigation conditions. Soil SAP (45 kg hm−2) was applied while sowing, and FA solution (2 g L−1) was sprayed onto the crop canopy three times at later plant growth periods.RESULTSCombining SAP and FA application significantly improved plant photosynthesis, chlorophyll contents and instantaneous WUE while maintaining optimal leaf stomatal transpiration. The effect of using the combined chemicals on photosynthesis and leaf instantaneous WUE was superior to the effects of their individual applications. Compared with plots not treated with chemicals, soil SAP significantly improved the yield by 12% and grain WUE by 10% when averaged across the two experiments, whereas foliar FA application did not affect yield and grain WUE. In contrast, the combined use of the two chemicals significantly increased the yield by 20% and grain WUE by 26%, largely attributed to the increase in grain number.CONCLUSIONSoil SAP and foliar FA use under low rainfall conditions had little influence on crop water consumption but improved plant WUE by enhancing photosynthesis and increasing kernel number. © 2018 Society of Chemical Industry
