AbstractPurposeThe primary aim of this study was to evaluate early changes in cardiac function after anthracycline therapy with layer‐specific speckle‐tracking echocardiography (STE) and mechanical dys‐synchrony.MethodsA total of 78 breast cancer patients (ranging 31~72 years) exposed to anthracycline treatment were recruited in this study. All patients received both conventional two‐dimensional speckle‐tracking echocardiographs at baseline, as well as after the completion of 2 and 4 cycles of the regimen. Layer‐specific longitudinal strain (LS) and circumferential strain (CS) of the 3 myocardial layers (endocardium, mid‐myocardium, and epicardium) were automatically measured. Peak systolic dispersion (PSD) was defined as the standard deviation of the time to peak strain of the 18 segments, divided by the RR interval.ResultsThere were no significant differences in conventional echocardiographic parameters during treatment (all P > .05). Peak endocardium CS at basal level decreased significantly after 2 and 4 cycles compared with baseline (both P = .001), while PSD significantly increased in that same period versus baseline (both P = .000). Endocardium and mid‐myocardium LS, peak mid‐myocardium and epicardium CS at the basal level, peak CS of all three layers at the papillary level, and peak endocardium and mid‐myocardium CS at the apical level all significantly decreased after 4 cycles, compared with baseline and 2 cycles (all P = .000).ConclusionThis study showed that myocardial deformation impairment occurred as early as 2 cycles after anthracycline chemotherapy. Endocardium CS at the basal level and left ventricular dys‐synchrony index PSD were the initial cardiac abnormalities in anthracycline‐treated breast cancer patients.

AbstractRecent studies have shown that slow cortical potentials in archi‐, paleo‐ and neocortex can phase‐lock with nasal respiration. In some of these areas, gamma activity (γ: 30–100 Hz) is also coupled to the animal's respiration. It has been hypothesized that these functional relationships play a role in coordinating distributed neural activity. In a similar way, inter‐cortical interactions at γ frequency have also been associated as a binding mechanism by which the brain generates temporary opportunities necessary for implementing cognitive functions. The aim of the present study is to explore whether nasal respiration entrains inter‐cortical functional interactions at γ frequency during both wakefulness and sleep. Six adult cats chronically prepared for electrographic recordings were employed in this study. Our results show that during wakefulness, slow cortical respiratory potentials are present in the olfactory bulb and several areas of the neocortex. We also found that these areas exhibit cross‐frequency coupling between respiratory phase and γ oscillation amplitude. We demonstrate that respiratory phase modulates the inter‐cortical gamma coherence between neocortical electrode pairs. On the contrary, slow respiratory oscillation and γ cortical oscillatory entrainments disappear during non‐rapid eye movement and rapid eye movement sleep. These results suggest that a single unified phenomenon involves cross‐frequency coupling and long‐range γ coherence across the neocortex. This fact could be related to the temporal binding process necessary for cognitive functions during wakefulness.

Published: August 2019

AbstractAs haze intensifies in China, controlling haze emission has become the country's top priority for environmental protection. Because haze moves across different regions, it is necessary to develop a data envelopment analysis (DEA) model underpinned by both competition and cooperation to evaluate the haze emission efficiency in different provinces. This study innovatively adopts the spatial econometrics to construct the co‐opetition matrices of Chinese provinces, then builds the co‐opetition DEA model to evaluate the haze emission efficiency of them, and finally uses the haze data of 2015 as an example to assess the applicability of the model. The results of the study include the following: First, compared with the traditional CCR (A. Charnes & W. W. Cooper & E. Rhodes) model, this study constructs the co‐opetition DEA cross‐efficiency model that integrates haze's feature of cross‐border moving; thus, it is more in line with the reality of haze emission and movement. Second, compared with the efficiency value gained from the CCR model, the haze emission efficiency values for Tianjin and Guangdong, two decision‐making units, register greater variance when using the DEA model. The reason might lie in that they have a different spatial transportation relationship with their surrounding provinces. Third, the haze emission efficiency of provinces, according to the evaluation based on the co‐opetition DEA method, varies greatly: Those with high efficiency are mostly inland provinces with slow economic growth and adverse climatic conditions, whereas many of the provinces with low efficiency are located in the relatively prosperous East China. The specific co‐opetition DEA model constructed in this study enriches the research on the DEA model, which can be applied to the emission efficiency evaluation of similar pollutants around the world and can contribute empirical support to the haze reducing efforts of the government with its empirical results.
Hazards of managing disparate species as a pooled complex: A general problem illustrated by two contrasting examples from Hawaii
Authors: DeMartini Edward E. 
Published: August 2019

AbstractSurprisingly little published information exists on the pros and cons of managing extracted resources that are pooled as compound taxa such as species complexes. Current fisheries management includes many species complexes; in Hawaii, this includes two taxa of species pooled at subfamily and higher levels. These include seven species of parrotfishes (Scarinae, Labridae) and a seven‐species ‘bottomfish’ complex (the ‘Deep‐7’: comprising six species of snappers [Etelinae, Lutjanidae] and a single species of grouper [Epinephelidae]). Recent research on key vital rates (growth, reproduction) for major species in both taxa indicates that these complexes consist of species with disparate life histories. Species in the parrotfish taxon exhibit fast to very fast growth and short to moderate longevities, whilst Deep‐7 bottomfishes exhibit moderate to very slow growth and long to very long lifespans. These data clearly indicate that, although pooling species is a tempting default option in data‐poor situations, it is at best a necessary evil to be avoided when sufficient data on the demographics of component species become available. Pooling species is especially problematic when the ecosystem effects of extracting functionally dominant species should be an important management consideration in addition to that of species demographics. Assessments that recognize and quantify the ecosystem importance of habitat engineers and other ecological dominants could substantively improve management of species complexes. Ultimately, complexes of resource species need to be evaluated and managed based on many, sometimes conflicting and sometimes reinforcing, but always careful considerations such as those contrasted herein between the parrotfishes and bottomfishes of Hawaii.

Background/ObjectivesDifferent triggers including environmental, hormonal, and dietary factors have been introduced as migraine risk factors. There is some evidence to suggest that a high quality of diet could be effective regarding management of migraine. In this present study, we hypothesized that the diet quality of women with chronic migraine (CM) might be different from women with episodic migraine (EM).MethodsIn this cross‐sectional study, 116 women with chronic and 169 women with episodic migraine (25‐55 years old) were recruited from the neurology clinics of Golestan hospital in Ahvaz (southwest Iran) based on the International Classification of Headache Disorders‐III. Anthropometric data including weight, height, waist, and hip circumference were measured. Dietary intake data were obtained using a reliable and valid semi‐quantitative food frequency questionnaire that included 168 food items. The diet quality of subjects was calculated using the Healthy Eating Index‐2015 (HEI‐2015).ResultsThe mean HEI score of participants was 57.29 ± 7.98. The participants were classified into 3 groups of “poor,” “needs improvement,” and “good” based on their diet quality. The frequencies of each group were 50/285 (17.5%), 233/285 (81.8%), and 2/285 (0.7%), respectively. Moreover, the mean of HEI score in women with CM was significantly lower than women with EM (55.93 ± 7.90 vs 58.93 ± 7.93, P = .02). Moreover, there was a significant negative association between CM and HEI score of women (β = −2.03; 95% CI: [−3.97 to −0.10]; P = .04).ConclusionsWomen with CM had a lower diet quality than that of EM. Moreover, CM was significantly and inversely associated with HEI score in women.

ObjectivesThe aim of the study was to estimate rates of linkage to HIV care and antiretroviral treatment (ART) initiation after the introduction of home‐based HIV counselling and testing (HBHCT) and telephone‐facilitated support for linkage in rural South Africa.MethodsA population‐based prospective cohort study was carried out in KwaZulu Natal, South Africa. All residents aged ≥ 15 years were eligible for HBHCT. Those who tested positive and were not in care were referred for ART at one of 11 public‐sector clinics. Individuals who did not attend the clinic within 2 weeks were sent a short message service (SMS) reminder; those who had not attended after a further 2 weeks were telephoned by a nurse counsellor, to discuss concerns and encourage linkage. Kaplan–Meier methods were used to estimate the proportion of newly diagnosed individuals linking to care and initiating ART.ResultsAmong 38 827 individuals visited, 26% accepted HBHCT. Uptake was higher in women than in men (30% versus 20%, respectively), but similar in people aged < 30 years and ≥ 30 years (28% versus 26%, respectively). A total of 784 (8%) tested HIV positive, of whom 427 (54%) were newly diagnosed. Within 6 months, 31% of women and 18% of men < 30 years old had linked to care, and 29% and 16%, respectively, had started ART. Among those ≥ 30 years, 41% of women and 38% of men had linked to care within 6 months, and 41% and 35%, respectively, had started ART.ConclusionsDespite facilitated linkage, rates of timely linkage to care and ART initiation after HBHCT were very low, particularly among young men. Innovations are needed to provide effective HIV care and prevention interventions to young people, and thus maximize the benefits of universal test and treat.

Published: August 2019

AbstractThe Western Paleartic species ofNeocrepidoderaHeikertinger (Coleoptera: Chrysomelidae: Galerucinae: Alticini) mostly occur in medium and high elevation ecosystems particularly sensitive to climate change.Here, using ensemble projections from state‐of‐the‐art habitat suitability modelling techniques, we investigated how climate change and associated changes in host availability may affect the persistence of three pairs of closely relatedNeocrepidoderataxa.Modelled niches and suitability patterns reflected the current distributions of the targeted taxa.Neocrepidodera liguricaoccupies a small portion of the broader environmental niche ofN. melanostoma, and its narrow geographical range makes this species particularly vulnerable to potential loss of suitable habitats in Western Alps.Neocrepidodera cyanescens cyanescensandN. cyanescens concolorwere found to occupy separate niches, but the non‐significance of the niche similarity test suggested their divergence being probably due to allopatric processes.Neocrepidodera corpulentaandN. rhaeticashowed partially overlapping niches, coherently with their co‐occurrence in Western Alps. Most of the targeted taxa were predicted to potentially lose large portions of currently suitable areas in the forthcoming decades.Notwithstanding the candidate host plants did not emerge as most important predictors, exceptAconitum lycoctonumforN. cyanescens concolor, a clear reduction of potential insect‐plant co‐occurrence areas resulted for most future scenarios.Climate was confirmed to noticeably affect the distribution of the targeted taxa, among whichN. ligurica,N. cyanescens concolor,N. corpulentaandN. rhaeticamay need specific prioritisation measures in the future decades, claiming for further attention on mountainous entomofauna in a warming world.

AbstractAimTo report the most common terminology used in titles of scientific papers published in the International Endodontic Journal (IEJ) and Journal of Endodontics (JOE) between 1980 and 2019 and to identify the most‐cited papers in these journals.MethodologyThe Web of Science database was searched to retrieve all the manuscripts published in the IEJ and JOE between 1980 and 2019. The articles were analysed using the VOS viewer software and the terms within the titles extracted. The top‐10 terms were categorized according to the number of occurrences and the decade of publication. Maps were created using the text data for each decade of publication. Classic papers were identified when the number of citations was >400. During the same period of time, highly cited studies were identified including the authors, institutions and countries associated with these papers.ResultsTerms such as canal, molar and periapical lesion were the most commonly used in titles between 1980 and 1999. The terms instruments, expression, case report and cell were the most often terms used between 2000 and 2019. During the last 10 years, an increase in the number of reviews and papers on cone beam computed tomography occurred. The organizations with the largest number of citations in each decade were University of São Paulo, University College London, Loma Linda University and United States Army. The country with the largest number of citations and greatest number of top 10 and top 100 manuscripts was the United States. A paper had to be associated with more than 167 citations to be included in the top‐100 most‐cited list; at least 14 papers met the criteria to be categorized as a citation classic (>400 citations).ConclusionWhile many diverse areas of endodontics have been explored in the last 40 years within the IEJ and JOE, only a relatively few topics are highly cited and can be considered as classics.
Are They Deterred by Welfare? Digging into the Drivers of Highly Skilled Temporary and Long‐term Migrants in Europe
Authors: Cebolla‐Boado Héctor , Miyar‐Busto María 
Published: August 2019

AbstractLiterature researching the drivers of highly skilled migration (HSM) often prioritizes labor market returns to education and downscales the importance of public welfare. This article develops an innovative empirical strategy which allows us to see how a selection of pull factors attracts temporary and long‐term educated migrants in Europe. To do so, we built a unique longitudinal contextual dataset merging information from the European Labor Force Survey (2000‐2014) with selected Eurostat and OECD country indicators. Country‐fixed effect time series allow us to concentrate on cross‐country effects. Our evidence suggests that returns to education attract temporary HSM and long‐term stayers equally. However, it is also shown that public welfare and taxation operate differently for these two groups and do not deter long‐term residents. Our article proposes revisiting the assumption that HSMs are mere income maximizers. As we argue, long‐term HSM may well be attracted by generous welfare setups.
Explaining the link between technostress and technology addiction for social networking sites: A study of distraction as a coping behavior

Published: August 2019

AbstractThis paper investigates under what conditions stress from the use of SNS is linked to addiction to the use of the same SNS. Integrating three theoretical strands—the concept of feature‐rich Information Technology (IT), the theory of technology frames, and distraction as a coping behaviour—we theorize two types of coping behaviours in response to stressors experienced from the use of SNS. These are ‐ distraction through use of the same SNS and distraction through activities outside the use of the SNS. We hypothesize relationships between stressors from SNS use, the two coping behaviours and SNS addiction. We further articulate the role of SNS use habit. We test the hypotheses through a three‐wave survey of 444 Facebook users with data collected at three different points in time. The paper's contributions are to theorize and empirically validate the psychological concept of distraction as a coping behaviour in response to stress from the use of SNS and, in doing so, explain why there may be a link between technostress from and technology addiction to the use of the same SNS.
Multiparty sensemaking: A technology‐vendor selection case study
Authors: Yeow Adrian Yong Kwang , Chua Cecil Eng Huang 
Published: August 2019

AbstractInformation system (IS) procurement history is replete with poorly executed, multimillion dollar procurement decisions. Yet we barely understand what effective IS procurement should look like. IS procurement is highly challenging, as it requires the client to simultaneously select a technology and vendor. This paper explores the technology‐vendor selection process through the sensemaking perspective. Our study develops a sensemaking model for technology‐vendor selection that connects the multiple rounds of client‐vendor communicative actions with the client's sensemaking process. We show how the client reconciles fragmented and sometimes conflicting cues and information through three intertwined cycles: immediate, retrospective, and decision. Sensebreaking occurs as a separate process (and not a communicative action) when disruptive cues occur persistently and from different vendors over multiple rounds of sensemaking. We derive a set of critical factors, on the basis of the sensemaking perspective, for selecting an appropriate vendor and technical solution. These insights in turn help explain many poorly executed IS procurement decisions.

AbstractAimsTo assess the effectiveness of physical‐procedural interventions in reducing pain during intramuscular injections.DesignSystematic review and meta‐analysis.MethodEnglish keywords were used to search databases [MEDLINE (OVID, Ebsco), SCOPUS, Science Direct, COCHRANE and the reference lists from retrieved articles] from their inception to November 2017 and randomized and quasi‐experimental trials were selected based on inclusion and exclusion criteria. The standardized mean difference and random effects model were used.ResultsFrom 2,318 articles, 15 articles (1996–2017) met the criteria for the meta‐analysis. Physical‐procedural interventions described in the articles were included in this systematic review. The overall standardized mean difference was 0.595 (95% confidence interval (CI) = 0.417–0.773), indicating a moderate effect on pain levels. Generally, these interventions (two‐needle technique, acupressure, manual pressure, ShotBlocker, Z‐technique, air‐lock technique, injection site postinjection massage, and speed of injection) have been found to moderately reduce pain.ConclusionIt seems difficult to conclude that a single intervention reduces pain in adults. However, we can state that the most effective interventions for reducing pain during intramuscular injections in adults involve the ventrogluteal site, the Z‐technique, and manual pressure.ImpactThe systematic review will provide guidance to clinicians, staff, and educator nurses and future studies. The systematic review will help nurses and educators apply techniques based on evidence in any setting. The systematic review will guide well‐designed and well‐reported studies to contribute to the accumulation of evidence in nursing research.

AbstractAimsTo describe the associations between dysphagia and malnutrition risk and to identify predictors for dysphagia in a group of persons at risk of malnutrition in hospitals and nursing homes.DesignA secondary analysis of cross‐sectional data from the years 2012–2016.MethodsThe risk of malnutrition was assessed using the Malnutrition Universal Screening Tool for Adults (MUST). The data were compared regarding malnutrition risk and dysphagia. Regression analyses were conducted to identify variables that were associated with the risk of malnutrition and dysphagia.ResultsPatients (N = 17,580) were included in the study sample. The prevalence of dysphagia was 6.6% and the prevalence of malnutrition risk was 18.9%. A multivariable logistic regression analysis resulted in the identification of dysphagia and cancer as variables with the highest odds ratios with regard to malnutrition risk. Patients with cancer, stroke or respiratory diseases represent a high‐risk group for the co‐occurrence of dysphagia and risk of malnutrition.ConclusionsScreening for dysphagia should be carried out on patients at risk of malnutrition as an integral part of their admission to a healthcare institution and especially on the higher risk group of patients with cancer, a stroke or a respiratory disease.ImpactWhat problem did the study address? This study identified the relationship between dysphagia and malnutrition risk and associated factors. What were the main findings? Dysphagia among patients in the research sample was associated with more than two times higher prevalence of the malnutrition risk. Where and on whom will the research have an impact? Thorough malnutrition risk and dysphagia screening lead to better nursing care.
