Objective

To investigate the efficacy of prophylactic administration of low-dose landiolol on postoperative atrial fibrillation (POAF) in patients after cardiovascular surgery.

Methods

Consecutive 150 patients over 70 years of age who underwent cardiovascular surgery for valvular, ischemic heart, and aortic diseases were enrolled in this single-center prospective randomized control study from 2010 to 2014. They were assigned to three treatment groups: 1γ group (landiolol at 1 μg/kg/min), 2γ group (landiolol at 2 μg/kg/min), or control group (no landiolol). In the two landiolol groups, landiolol hydrochloride was intravenously administered for a period of 4 days postoperatively. Electrocardiography was continuously monitored during the study period, and cardiologists eventually assessed whether POAF occurred or not.

Results

POAF occurred in 24.4% of patients in the control group, 18.2% in 1γ group, and 11.1% in 2γ group (p = 0.256). Multivariate logistic regression analysis showed that the incidence of POAF tended to decrease depending on the dose of landiolol (trend-p = 0.120; 1γ group: OR = 0.786, 95% CI 0.257–2.404; 2γ group: OR = 0.379, 95% CI 0.112–1.287). Subgroup analysis showed a significant dose-dependent reduction in POAF among categories of female sex, non-use of angiotensin II receptor blockers (ARBs) before surgery, and valve surgery (each trend-p = 0.02, 0.03, and 0.004).

Conclusions

These findings indicate that prophylactic administration of low-dose landiolol may not be effective for preventing the occurrence of POAF in overall patients after cardiovascular surgery, but the administration could be beneficial to female patients, patients not using ARBs preoperatively, and those after valvular surgery.
Red Blood Cells Mean Corpuscular Volume (MCV) and Red Blood Distribution Width (RDW) Parameters as Potential Indicators of Regenerative Potential in Older Patients and Predictors of Acute Mortality – Preliminary Report
Authors: Brzeźniakiewicz-Janus Katarzyna , Rupa-Matysek Joanna , Tukiendorf Andrzej , Janus Tomasz , Franków Mirosław , Lancé Marcus Daniel , Gil Lidia
Published: May 2020

This study presents the statistical results of patients who had been recently discharged from hospital within one month after their treatment in the emergency department (ED). Using routine (14,881) MCV and RDW measurements and statistical tools, we could predict acute mortality in these patients (N = 1158), adjusted for age. It is likely that an increase in the MCV and RDW parameters may correlate in some of our older patients with a poor prognosis with an increased level of circulating IGF–I, which affects red blood cell parameters. The research presents the prognostic statistics of the analyzed clinical factors as well as speculates on the potential correlation of these parameters with the regenerative potential of stem-cell compartment. Analysis shows that both MCV and RDW are statistically significant (Area Under Curve [AUC], lower CI 95% >50%) predictors of acute mortality in ED patients. The classification of patients based on their MCV threshold (= 92.2 units) indicates a proper clinical prognosis in nearly 6 of 10 subjects (AUC >58%), whereas taking into account RDW (=13.8%) indicates a proper clinical prognosis in no more than 7 of 10 individuals. The report concludes that by employing strongly fitting (95%) quadratic modeling of the ORs against the biomarkers studied, one can notice a similar relationship between MCV and RDW as diagnostic tools to predict regenerative potential and clinical outcomes in older patients. Although RDW alone had a 10% higher diagnostic value in terms of predicting early death in the emergency department in patients that were admitted to the ED and subsequently hospitalized, also taking the MCV measurement improved accuracy in predicting clinical outcomes by 2.5% compared to RDW alone.
The Effect of an Increase of the Retirement Age on the Health, Well-Being, and Labor Force Participation of Older Workers: a Systematic Literature Review
Authors: Pilipiec Patrick , Groot Wim , Pavlova Milena
Published: May 2020

To sustain a viable public pension system, many governments have increased the statutory retirement age and delayed the age of entitlement to public pension benefits. This systematic literature review investigates the empirical evidence on the effects of increasing the retirement age on the health, well-being, and labor force participation of older workers. Optimized and broad search queries were used to search for empirical evidence in four databases: EconLit, PsycINFO, PubMed, and SocINDEX. The systematic literature search was conducted in May 2019. Snowballing was performed on the reference lists of the publications to find additional studies. The quality of the included studies was also examined. The PRISMA guidelines were used to guide this systematic literature review. Nineteen studies were included in this review. Twelve studies estimated the effect of an increase in the statutory retirement age, and seven studies examined working beyond the retirement age. The reported findings were classified into health-related outcomes, well-being, and the effects on labor force participation and the perception of the retirement age. The reported findings regarding health-related outcomes and well-being were not comparable. The increase of the retirement age has increased labor force participation among older workers and has increased the preferred and expected retirement age in the direction of the public pension reform. However, evidence on the effects of an increase of the retirement age on the health and well-being of older workers remains scarce and inconclusive.

Published: May 2020

Fusarium infections have been reported in aquatic animals, but are still poorly investigated in wild salmonids. The aim of the study was to determine the impact of the fungi and their toxins on the health status of brown trout (Salmo trutta morpha trutta) migrating from the Baltic Sea to the freshwater. Individuals from the wild brown trout population exhibiting ulcerative skin lesions were collected from the Słupia River in Poland and subjected to microbiological, histopathological, and hematological examinations, as well as toxicological analysis for a presence of mycotoxins. The results of microflora isolation from the brown trout skin samples revealed the presence of conditionally pathogenic bacteria and fungi classified by molecular techniques as Fusarium spp. Toxicological analysis allowed for detection of zearalenone (ZEN) in the liver, kidney, and gastrointestinal tract of the fish. In several cases, there was α-zearalenone (α-ZEL) identified at trace levels in the liver, as well as sterigmatocystin and enniatin B at low levels in the kidney and the liver. Histopathological examination revealed the presence of fungal hyphae disrupting the epidermis and penetrating into the necrotic dermis and hypodermis. The decreased values of the blood parameters, i.e., hemoglobin concentration (HGB), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and white blood cell count (WBC), were indicative of osmoregulation failure being a consequence of the skin damage. The results of the study provide new information regarding Fusarium sp. infection in brown trout and serve as the basis for further research on the potential impact of the fungi and their mycotoxins on the Baltic salmonid population, including their role in ulcerative dermal necrosis.

Der Beitrag untersucht, wie das AnKER-Zentrum als machtvolle Organisation der Asylverwaltung konzeptionell entworfen wird. AnKER ist ein Akronym für „Ankunft, Entscheidung und Rückführung“. Im Mittelpunkt des Beitrags steht eine objektiv-hermeneutische Analyse eines Auszugs aus dem Koalitionsvertrag der Großen Koalition aus dem Frühjahr 2018. Ziel ist eine Rekonstruktion der Mechanismen der Asylverwaltung, die in diesem Dokument zum Ausdruck kommen. Zentrales Ergebnis ist, dass der Koalitionsvertrag das AnKER-Zentrum als Kontrollinstanz konstruiert. Die Unterbringung geht mit einem Zugriff auf Körper, Biografie und Bewegung der Betreffenden einher. Sie werden vermessen, klassifiziert und letztlich ihren Herkunftsländern oder den Kommunen in Deutschland zugewiesen. Mit Michel Foucault lassen sich AnKER-Zentren als Disziplinarinstitutionen fassen. Sie zielen auf ein Einhalten behördlicher Regularien, während sozialarbeiterisches Handeln fall- und lebensweltbezogen ausgerichtet sein soll. Der Beitrag reflektiert auf Basis der Analyseergebnisse die Notwendigkeit Sozialer Arbeit, sich als organisationsbasierte Profession zu begreifen und in die Ausgestaltung von Geflüchtetenunterkünften zu involvieren.
Impacts of Elevated Atmospheric CO2 and Plant Species Composition on Methane Emissions from Subarctic Wetlands
Authors: Bridgman Matthew J. , Lomax Barry H. , Sjögersten Sofie
Published: May 2020

Elevated atmospheric CO2 may create greater methane (CH4) emissions from subarctic wetlands. To date such ecosystem feedbacks remain poorly understood, particularly in relation to how different wetland plant species will control such feedbacks. In this study we exposed plant-peat mesocosms planted with four Cyperaceae species to 400 and 800 ppm atmospheric CO2 concentrations and measured plant and peat properties as well as CH4 fluxes. Above ground biomass for plants grown at 800 ppm CO2 increased for E. angustifolium, Eriophorum vaginatum and Carex brunnescens, but the total biomass of C. acuta decreased relative to the ambient CO2 treatment. The plant species and elevated CO2 treatment affected both peat redox potential and pore water chemistry. There was no overall effect of the elevated CO2 on CH4 emissions, however, CH4 emissions were related to above ground biomass and redox potential, both of which were significantly altered by elevated CO2. Our study shows that species composition poses an important control on how wetland communities will respond to elevated CO2 and that plant mediated changes of peat biogeochemical processes, in response to elevated CO2 levels, may affect CH4 emissions from sub-arctic wetlands, but any such responses will differ among species.
Reassessing the Size of Mormons, Adventists and Witnesses: Using Census Data to Test the Reliability of Membership Data and Accounting for the Disparate Patterns Found
Authors: Lawson Ronald , Xydias G. Kenneth
Published: May 2020

This article compares the growth of three religious groups, the Church of Jesus Christ of Latter-day Saints, Seventh-day Adventists, and Jehovah's Witnesses. All originated in America during the nineteenth century and have since globalized. It begins by using their official membership data to contrast their aggregate growth over time. It then questions the reliability of those official statistics. Noting that each group employs different criteria in selecting who it counts, it employs census data from 54 countries in all regions of the world and five surveys of US adult religious affiliation with adjustments for children as a proxy for an American census to provide a common basis for comparison. It finds consistent patterns, where membership data greatly overstate the number of Mormons, understate the number of Adventists, and also understate the number of Witnesses to an even greater extent. The article then calculates a weighted ratio between official and census data for each group and uses those ratios to estimate their aggregate adherents. This method results in a dramatic reordering of their sizes. Finally, the article accounts for the variations found between the three groups.
Outcome of spinal implant-associated infections treated with or without biofilm-active antibiotics: results from a 10-year cohort study
Authors: Köder Karolin , Hardt Sebastian , Gellert Max S. , Haupenthal Judith , Renz Nora , Putzier Michael , Perka Carsten , Trampuz Andrej
Published: May 2020

Purpose

Biofilm-active antibiotics are suggested to improve the outcome of implant-associated infections; however, their role in infections after spinal instrumentation is unclear. Therefore, we evaluated the outcome of patients with spinal implant-associated infections treated with and without biofilm-active antibiotics.

Methods

The probability of infection-free survival was estimated for treatment of spinal implant-associated infections with and without biofilm-active antibiotics using the Kaplan–Meier method; Cox proportional-hazards regression model was used to identify factors associated with treatment failure.

Results

Among 93 included patients, early-onset infection was diagnosed in 61 (66%) and late-onset in 32 infections (34%). Thirty patients (32%) were treated with biofilm-active antibiotic therapy and 63 (68%) without it. The infection-free survival after a median follow-up of 53.7 months (range, 8 days-9.4 years) was 67% (95% confidence interval [CI], 55–82%) after 1 year and 58% (95% CI 43–71%) after 2 years. The infection-free survival after 1 and 2 years was 94% (95% CI 85–99%) and 84% (95% CI 71–93%) for patients treated with biofilm-active antibiotics, respectively, and 57% (95% CI 39–80%) and 49% (95% CI 28–61%) for those treated without biofilm-active antibiotics, respectively (p = 0.009). Treatment with biofilm-active antibiotics (hazard ratio [HR], 0.23, 95% CI 0.07–0.77), infection with Staphylococcus auras (HR, 2.19, 95% CI 1.04–4.62) and polymicrobial infection (HR, 2.44, 95% CI 1.09–6.04) were significantly associated with treatment outcome. Severe pain was observed more often in patients without biofilm-active antibiotic therapy (49% vs. 18%, p = 0.027).

Conclusion

Treatment with biofilm-active antibiotics was associated with better treatment outcome and less postoperative pain intensity.
Diskriminierungserfahrungen und Bedrohungswahrnehmungen von in Deutschland lebenden Juden
Authors: Beyer Heiko , Liebe Ulf
Published: May 2020

Basierend auf Daten des Jahres 2018 der Fundamental Rights Agency der Europäischen Union ermittelt der vorliegende Beitrag Ausmaß und Faktoren antisemitischer Vorurteilskriminalität in Deutschland. Zum einen werden die Erfahrungen von in Deutschland lebenden Jüdinnen und Juden mit persönlichen Belästigungen und Beleidigungen, Vandalismus und körperlicher Gewalt innerhalb eines Zeitraumes von fünf Jahren vor dem Erhebungszeitpunkt beleuchtet. Zum anderen beschäftigen wir uns mit der geäußerten Furcht, zukünftig Opfer antisemitischer Übergriffe zu werden. Erfahrungen mit Gewalt und Vandalismus berichten 7 % der 1225 Befragten, und 44 % wurden in den letzten fünf Jahren belästigt, weil sie jüdisch sind. Vor allem Personen, die aufgrund des Tragens von Symbolen als Juden erkennbar sind, waren betroffen und vermeiden gelegentlich oder öfter Plätze in der lokalen Umgebung, weil sie sich dort unsicher fühlen. Wenn die Befragten hingegen in einer mehrheitlich jüdischen Nachbarschaft lebten, sank die Wahrscheinlichkeit Opfer von Belästigungen und Gewalttaten zu werden. Belästigt und beleidigt wurden zudem besonders religiöse Menschen und Personen, die die Unterstützung von Israel als sehr wichtig für ihre jüdische Identität erachten. Diese Personen fühlen sich, ebenso wie jene, die dem Erinnern an den Holocaust eine hohe Bedeutung beimessen, zudem stärker bedroht – eine Bestätigung der Vermutung, dass sekundärer und israelbezogener Antisemitismus ein großes Bedrohungspotential in der aktuellen gesellschaftlichen Situation darstellen. Als Reaktion auf die empfundene Bedrohung verzichten die Befragten zwar laut der vorliegenden Befragung nicht auf das Tragen von jüdischen Symbolen, aber stärkere Bedrohungswahrnehmungen korrelieren mit dem Vermeiden von als gefährlich eingeschätzten Plätzen sowie von jüdischen Veranstaltungen.
Low-energy desalination system has the potential to mitigate the effects of water shortages across the Middle East

Published: May 2020

In a number of countries around the world, groundwater resources are increasingly depleted and salinised. Desalination can be energy intensive and costly, but the collaborative project briefly described in this article is seeking to change this. At the heart of this project is a low-energy desalination system. The technology, which is being developed by researchers in the UK, aided by Israeli, Jordanian and Palestinian academics and students, has the potential to help mitigate the effects of water shortages across the Middle East and other regions worldwide.

Model for sectional leading-edge vortex lift for the prediction of rotating samara seeds performance
Authors: Rezgui D. , Arroyo I.H. , Theunissen R.
Published: May 2020

This article presents a development of a simple analytical aerodynamic model capable of describing the effect of leading-edge vortices (LEVs) on the lift of rotating samara wings. This analytical model is based on the adaptation of Polhamus’ method to develop a sectional two-dimensional lift function, which was implemented in a numerical blade element model (BEM) of a rotating samara blade. Furthermore, wind tunnel experiments were conducted to validate the numerical BEM and to assess the validity of the newly developed analytical lift function. The results showed good agreement between the numerical model and the experimental measurements of rotational speed and rate of descent of the samara wing. The results were also compared with numerical predictions using BEM but adopting different lift coefficient expressions available in literature. This research contributed towards efficient aerodynamic modelling of the lift generated by LEVs on rotating samara wings for performance prediction, which could potentially be used in the design of bio-inspired rotary micro-air vehicles.
Conservancies, Conflict and Dispossession: The Winners and Losers of Oil Exploration in Turkana, Kenya
Authors: Mkutu Kennedy , Mdee Anna
Published: May 2020

Formerly marginal areas are increasingly the focus of extractive mega-projects, which are framed as necessary for economic growth and a modern industrial economy. Yet there are concerns that such projects are unjustly displacing local populations, facilitated through the alliances of local elites with foreign investors. This article asks, who are the winners and losers from oil exploration in the Turkana region of Kenya? Using longitudinal ethnographic research on the dynamics of local government, oil exploration, and pastoralist livelihoods in Turkana, Mkutu and Mdee highlight how current processes may exacerbate inequality and marginalization, with the potential for increasingly violent consequences.
Attitude of Jordanian Nursing Educators Toward Integration of Disaster Management in Nursing Curricula
Authors: Alkhalaileh Murad
Published: May 2020

Objective:

Nursing education plays a significant role in preparing nurses for disasters; it helps in increasing their knowledge about disasters. The purpose of this study was to explore the attitude of nursing educators in Jordan toward the integration of disaster preparedness contents in nursing curricula.

Method:

A descriptive cross-sectional survey was used. The instrument comprises 51 Likert-scale items; 150 questionnaires were distributed to nursing educators in all of the private and government universities. Data were analyzed using the Statistical Package for Social Science (SPSS), version 22 (IBM Corp, Armonk, NY).

Results:

One hundred thirty-one (131) results were collected with an 87% response rate. All participants perceived that the integration of a disaster course in nursing curricula is quite important. Findings indicated a lack of nursing educators’ life experiences regarding disaster management. No significant differences were found in terms of age, area of experience, or years of teaching. Incorporating disaster management courses into nursing curricula will help resolve the lack of knowledge.

Conclusion:

Nursing educators have a low level of knowledge in disaster management. This highlights the necessity for preparing nursing educators for disasters by encouraging their participation in disaster management training. Therefore, they will circulate this information adequately to students accordingly.

Published: May 2020

Objective:

Despite recommendations to discontinue prophylactic antibiotics after incision closure or <24 hours after surgery, prophylactic antibiotics are continued after discharge by some clinicians. The objective of this study was to determine the prevalence and factors associated with postdischarge prophylactic antibiotic use after spinal fusion.

Design:

Multicenter retrospective cohort study.

Patients:

This study included patients aged ≥18 years undergoing spinal fusion or refusion between July 2011 and June 2015 at 3 sites. Patients with an infection during the surgical admission were excluded.

Methods:

Prophylactic antibiotics were identified at discharge. Factors associated with postdischarge prophylactic antibiotic use were identified using hierarchical generalized linear models.

Results:

In total, 8,652 spinal fusion admissions were included. Antibiotics were prescribed at discharge in 289 admissions (3.3%). The most commonly prescribed antibiotics were trimethoprim/sulfamethoxazole (22.1%), cephalexin (18.8%), and ciprofloxacin (17.1%). Adjusted for study site, significant factors associated with prophylactic discharge antibiotics included American Society of Anesthesiologists (ASA) class ≥3 (odds ratio [OR], 1.31; 95% CI, 1.00–1.70), lymphoma (OR, 2.57; 95% CI, 1.11–5.98), solid tumor (OR, 3.63; 95% CI, 1.62–8.14), morbid obesity (OR, 1.64; 95% CI, 1.09–2.47), paralysis (OR, 2.38; 95% CI, 1.30–4.37), hematoma/seroma (OR, 2.93; 95% CI, 1.17–7.33), thoracic surgery (OR, 1.39; 95% CI, 1.01–1.93), longer length of stay, and intraoperative antibiotics.

Conclusions:

Postdischarge prophylactic antibiotics were uncommon after spinal fusion. Patient and perioperative factors were associated with continuation of prophylactic antibiotics after hospital discharge.
Psychiatric hospitalization rates in Italy before and during COVID-19: did they change? An analysis of register data
Authors: Clerici M. , Durbano F. , Spinogatti F. , Vita A. , de Girolamo G. , Micciolo R.
Published: May 2020

Objectives.

To assess admission rates to seven General Hospital Psychiatric Wards (GHPWs) located in the Lombardy Region in the 40 days after the start of Coronavirus disease 2019 (COVID-19) epidemic, compared to similar periods of 2020 and 2019.

Methods.

Anonymized data from the regional psychiatric care register have been obtained and analyzed. The seven GHPWs care for approximately 1.4 million inhabitants and have a total of 119 beds.

Results.

In the 40-day period (February 21–March 31, 2020) after the start of the COVID-19 epidemic in Italy, compared to a similar 40-day period prior to February 21, and compared to two 40-day periods of 2019, there has been a marked reduction in psychiatric admission rates. The reduction was explained by voluntary admissions, while there was not a noticeable reduction for involuntary admissions. The reduction was visible for all diagnostic groups, except for a group of ‘Other’ diagnoses, which includes anxiety disorders, neurocognitive disorders, etc.

Conclusions.

Large-scale pandemics can modify voluntary admission rates to psychiatric facilities in the early phases following pandemic onset. We suggest that the reduction in admission rates may be due to fear of hospitals, seen as possible sites of contagion, as well as to a change in thresholds of behavioral problems acting as a trigger for admission requests from family relatives or referrals from treating clinicians. It is unclear from the study whether the reduction in admissions was contributed to most by the current pandemic or the lockdown imposed due to the pandemic.
Personality neuroscience and psychopathology: should we start with biology and look for neural-level factors?
Authors: McNaughton Neil
Published: May 2020

“Personality is an abstraction used to explain consistency and coherency in an individual’s pattern of affects, cognitions, desires and behaviors [ABCDs]” (Revelle, 2007, p. 37). But personality research currently provides more a taxonomy of patterns than theories of fundamental causes. Psychiatric disorders can be viewed as involving extremes of personality but are diagnosed via symptom patterns not biological causes. Such surface-level taxonomic description is necessary for science, but consistent predictive explanation requires causal theory. Personality constructs, and especially their clinical extremes, should predict variation in ABCD patterns, with parsimony requiring the lowest effective causal level of explanation. But, even biologically inspired personality theories currently use an intuitive language-based approach for scale development that lacks biological anchors. I argue that teleonomic “purpose” explains the organisation and outputs of conserved brain emotion systems, where high activation is adaptive in specific situations but is otherwise maladaptive. Simple modulators of whole-system sensitivity evolved because the requisite adaptive level can vary across people and time. Sensitivity to a modulator is an abstract predictive personality factor that operates at the neural level but provides a causal explanation of both coherence and occasional apparent incoherence in ABCD variation. Neuromodulators impact all levels of the “personality hierarchy” from metatraits to aspects: stability appears altered by serotonergic drugs, neuroticism by ketamine and trait anxiety by simple anxiolytic drugs. Here, the tools of psychiatry transfer to personality research and imply both interaction between levels and oblique factor mappings to ABCD. On this view, much psychopathology reflects extremes of neural-level personality factors, and we can view much pharmacotherapy as temporarily altering personality. So, particularly for personality factors linked to basic emotions and their disorders, I think we should start with evolutionary biology and look directly at conserved neural-level modulators for our explanatory personality constructs and only invoke higher order, emergent, explanations when neural-level explanation fails.
Redeeming Santo Domingo: North Atlantic Missionaries and the Racial Conversion of a Nation
Authors: Davidson Christina Cecelia
Published: May 2020

This article examines North Atlantic views of Protestant missions and race in the Dominican Republic between 1905 and 1911, a brief period of political stability in the years leading up to the U.S. Occupation (1916–1924). Although Protestant missions during this period remained small in scale on the Catholic island, the views of British and American missionaries evidence how international perceptions of Dominicans transformed in the early twentieth century. Thus, this article makes two key interventions within the literature on Caribbean race and religion. First, it shows how outsiders’ ideas about the Dominican Republic's racial composition aimed to change the Dominican Republic from a “black” country into a racially ambiguous “Latin” one on the international stage. Second, in using North Atlantic missionaries’ perspectives to track this shift, it argues that black-led Protestant congregations represented a possible alternative future that both elite Dominicans and white North Atlantic missionaries rejected.
Elders and Deacons in Kampen and Wemeldinge: Dutch Reformed Approaches to Consistory Elections
Authors: Dieleman Kyle J.
Published: May 2020

The consistory was a crucial institution in early modern Reformed churches. This article examines the nominations and elections of elders and deacons in the Dutch Reformed consistories of Kampen and Wemeldinge, shedding light on who was being nominated and elected and how such processes functioned in these churches. In particular, research into the Kampen consistory records demonstrates the importance given to the office of elder despite little theological backing for such a hieararchy; this was true to a lesser extent in Wemeldinge. In addition, the Kampen civil authorities played a significant role in the life of the consistory, most notably through the service of burgomasters as elders. The presence of burgomasters on the consistory is not present in Wemeldinge, indicating a more separate relationship between the church and state. In both Kampen and Wemeldinge, the elections of elders and deacons were unique and responded to the challenges and priorities of the individual contexts and communities.
Genesis of coronae and implications of an early Neoproterozoic thermal event: a case study from SE Chotanagpur Granite Gneissic Complex, India
Authors: Adak Vedanta , Dutta Upama
Published: May 2020

Partial equilibrium textures such as corona provide information on changing pressure–temperature (P-T) conditions experienced by a rock during its geological evolution. Coronae layers may form in single or multiple stages; understanding the genesis of each layer is necessary to correctly extract information regarding the physicochemical conditions experienced by the rock. Mafic rocks from SE Chotanagpur Granite Gneissic Complex, India, show the presence of multi-layered coronae at olivine–plagioclase contact with the mineral sequence: olivine | orthopyroxene | amphibole + spinel | plagioclase. Textural studies indicate that the coronae formed during metamorphism in a single stage due to a reaction between olivine and plagioclase. Reaction modelling shows that the corona formation occurred in an open system and experienced a minor volume loss. Pseudosection modelling and thermobarometry suggest that theP-Tconditions related to corona formation are 860 ± 50°C and 7 ± 0.5 kbar. A μMgO-μCaOdiagram shows that the layers in coronae formed in response to chemical potential gradients between the reactant minerals. A combination of field observations and theP-Tconditions of coronae formation suggest a fluid-driven metamorphism. Correlation with extant geological information indicates that the corona-forming event is possibly related to the accretion of India and Antarctica during the assembly of Rodinia.
Salience and central executive networks track overgeneralization of conditioned-fear in post-traumatic stress disorder
Authors: Berg Hannah , Ma Yizhou , Rueter Amanda , Kaczkurkin Antonia , Burton Philip C. , DeYoung Colin G. , MacDonald Angus W. , Sponheim Scott R. , Lissek Shmuel M.
Published: May 2020

Background

Generalization of conditioned-fear, a core feature of post-traumatic stress disorder (PTSD), has been the focus of several recent neuroimaging studies. A striking outcome of these studies is the frequency with which neural correlates of generalization fall within hubs of well-established functional networks including salience (SN), central executive (CEN), and default networks (DN). Neural substrates of generalization found to date may thus reflect traces of large-scale brain networks that form more expansive neural representations of generalization. The present study includes the first network-based analysis of generalization and PTSD-related abnormalities therein.

Methods

fMRI responses in established intrinsic connectivity networks (ICNs) representing SN, CEN, and DN were assessed during a generalized conditioned-fear task in male combat veterans (N = 58) with wide-ranging PTSD symptom severity. The task included five rings of graded size. Extreme sizes served as conditioned danger-cues (CS+: paired with shock) and safety-cues (CS−), and the three intermediate sizes served as generalization stimuli (GSs) forming a continuum-of-size between CS+ and CS–. Generalization-gradients were assessed as behavioral and ICN response slopes from CS+, through GSs, to CS–. Increasing PTSD symptomatology was predicted to relate to less-steep slopes indicative of stronger generalization.

Results

SN, CEN, and DN responses fell along generalization-gradients with levels of generalization within and between SN and CEN scaling with PTSD symptom severity.

Conclusions

Neural substrates of generalized conditioned-fear include large-scale networks that adhere to the functional organization of the brain. Current findings implicate levels of generalization in SN and CEN as promising neural markers of PTSD.
Living with young onset dementia: reflections on recent developments, current discourse, and implications for policy and practice
Authors: Mayrhofer Andrea M. , Shora Shaheen , Tibbs Margaret-Anne , Russell Sarah , Littlechild Brian , Goodman Claire
Published: May 2020

Recent research on young onset dementia (formal diagnosis at age <65) evidences emerging work around pre-diagnosis, diagnosis and the need to improve post-diagnostic support for this group. An increased awareness of young onset dementia has led to the establishment of peer-support groups, support networks and the involvement of people affected by dementia in research. However, the need to join up services at the systems level persists. Third-sector organisations that offer post-diagnostic support at the community level rely heavily on volunteers. Implications for policy and practice are that community-based commissioning of integrated services between health care, social care and the third sector would go a long way to providing the continuity and stability required in dementia support and care along the illness trajectory. This discussion document was written in collaboration with diagnostic services, the charity sector and conversations with people living with, and affected by, dementia.
Coping with crisis: labour markets, institutional changes and household economies. An introduction
Authors: Martini Manuela , Borderías Cristina
Published: May 2020

Today as in the past, most often crises take people by surprise. This fact has recently provoked strong criticism of the ability of an economic theory to predict crises, to understand their course and to establish solutions to mitigate their effects. History can thus serve as a reservoir of facts and experiences, and the use of a broad chronological perspective has been recently highlighted as essential to providing a wider, comparative knowledge of past crises. Recent economic historiography has highlighted the importance of studying financial and commercial crises alongside agrarian and demographic crises, as well as questioning specific aspects of these shocks. Another important dimension stressed by recent historical studies is the importance of recognising that crises in the past occurred against a background in which uncertainty was the norm. In societies that experienced various forms of ordinary uncertainty (linked for example to the ‘dead’ season in food or textile production), crises constitute peaks of exceptional uncertainty.
Chinese Telecommunications Companies in Ethiopia: The Influences of Host Government Intervention and Inter-firm Competition
Authors: Fei Ding
Published: May 2020

This article examines Chinese engagement in Ethiopia's telecommunications sector. It argues that while theories of developmental state and global production networks contribute important insights on the roles of state agency and inter-firm relations in the rise of global lead firms from East Asia, they are insufficient to interpret the recent overseas ventures of Chinese companies in Africa. A case study of one flagship Chinese telecommunications company in Ethiopia advances the existing literature by highlighting the influences of host government intervention and inter-firm competition in shaping firms’ local operations. Specifically, this article analyses a myriad of changes in the case company's organizational structure and business practices in response to increased market competition administered by the Ethiopian government. Findings reveal that despite benefiting from official inter-state cooperation, Chinese overseas companies are neither static nor merely state-driven players but are flexible in adjusting strategies to improve their competitiveness in the local market.

Our study objective was to develop and validate a questionnaire assessing the knowledge, attitude, and practice (KAP) of family physicians regarding dementia care and dementia strategies in Canada. Using a multistage process with a panel of experts, we developed and distributed an 83-item questionnaire to 542 eligible family physicians in 42 interdisciplinary primary care teams participating in the Quebec Alzheimer Plan implementation. Altogether, 369 physicians (68%) returned questionnaires. Median item-specific non-response rate was 0.8 per cent (0.3%–8.1%). Exploratory factor analyses and scale correlation supported the questionnaire validity. The final questionnaire contained five factors and 31 items. The KAP questionnaire has proved to be a reliable instrument for assessing the KAP of family physicians regarding dementia care and dementia strategies. This questionnaire provides researchers, clinicians, managers, and decision-makers with a tool to assess an intervention, a program, or a policy change implemented in primary health care for patients with dementia.

Despite considerable efforts to understand the processes that underlie the development of externalizing behavior problems, it is still unclear why externalizing problems remain chronically high for some children, emerge early and cease by late childhood for others, and arise in adolescence in some cases. The purpose of this study was to examine how a wide range of child and family risk factors are linked to trajectories of externalizing behavior and how these relationships vary from infancy to middle adolescence. We used data from the community-based Norwegian Tracking Opportunities and Problems (TOPP) study sample (n = 921). A Cholesky factorization model was specified to separate stable and emerging risk doses across four developmental periods (infancy, early and middle childhood, and middle adolescence). Children in the High Stable class were characterized by substantially elevated risk levels in multiple domains throughout the study period. Children in the High Childhood Limited class had very high levels of temperamental emotionality, internalizing symptoms, and maternal mental distress, suggesting a substantial intrinsic emotional basis for their externalizing problems. Intrinsic factors seemed less salient for the Adolescent Onset class. These findings emphasize the need for a dynamic perspective on risk factors and support the importance of prevention and intervention efforts across multiple domains from early childhood and throughout adolescence.
THE TEMPLE OF QUETZALCOATL, TEOTIHUACAN: NEW DATA ON THE ORIGINS OF THE SACRIFICIAL VICTIMS

Continuing isotopic investigation of the sacrificial burials and trophies beneath the Feathered Serpent Pyramid (Temple of Quetzalcoatl) in ancient Teotihuacan, Mexico, has produced new results. Isotopic proveniencing using bioapatite strontium and structural carbonate oxygen isotopes in tooth enamel was applied to 39 samples, 24 from the sacrificial victims and 15 from the trophy jaws. Both the strontium and oxygen isotope ratios suggest that most or all of the sacrificial victims came from the central highlands of Mexico, which includes the area of Teotihuacan. In this sense, we find somewhat less multiethnicity represented among the military at Teotihuacan than previously thought. Analysis of carbon isotope ratios in enamel structural carbonate indicated a childhood diet dominated by maize, relatively homogeneous among the victims at the pyramid, and typical for much of pre-Hispanic Mesoamerica.

Published: May 2020

Background:

Chest pain, as a common cause of hospital admissions in childhood, necessitates detailed investigations due to a wide range of differential diagnoses. In this study, we aimed to determine the distribution of diseases causing chest pain in children and investigate the clinical characteristics of children with chest pain.

Methods:

This study included 782 patients aged between 3 and 18 years who presented to a paediatric cardiology outpatient clinic with chest pain between April 2017 and March 2018. Aetiological causes and demographic features of the patients were analysed.

Results:

Most prevalent causes of chest pain were musculoskeletal system (33%) and psychogenic (28.4%) causes. Chest pain due to cardiac reasons was seen in eight patients (1%). Diseases of musculoskeletal and gastrointestinal systems and psychogenic disorders were significantly more common in male and female patients, respectively (p < 0.001 for all). In winter, patients’ age and the number of patients with ≥12 years were higher than those in other seasons (p < 0.001). Most of the parents (70.8%) and patients (90.2%) thought that chest pain in their children was caused by cardiac causes.

Conclusion:

Most of the diagnoses for chest pain in childhood period are benign and include the musculoskeletal system and psychogenic diseases. Although chest pain due to cardiac diseases is rare, a comprehensive analysis of medical history, detailed physical examination and cardiac imaging with echocardiography is needed to reach more accurate diagnoses.
Compression versus traditional machine learning classifiers to detect code-switching in varieties and dialects: Arabic as a case study

The occurrence of code-switching in online communication, when a writer switches among multiple languages, presents a challenge for natural language processing tools, since they are designed for texts written in a single language. To answer the challenge, this paper presents detailed research on ways to detect code-switching in Arabic text automatically. We compare the prediction by partial matching (PPM) compression-based classifier, implemented in Tawa, and a traditional machine learning classifier sequential minimal optimization (SMO), implemented in Waikato Environment for Knowledge Analysis, working specifically on Arabic text taken from Facebook. Three experiments were conducted in order to: (1) detect code-switching among the Egyptian dialect and English; (2) detect code-switching among the Egyptian dialect, the Saudi dialect, and English; and (3) detect code-switching among the Egyptian dialect, the Saudi dialect, Modern Standard Arabic (MSA), and English. Our experiments showed that PPM achieved a higher accuracy rate than SMO with 99.8% versus 97.5% in the first experiment and 97.8% versus 80.7% in the second. In the third experiment, PPM achieved a lower accuracy rate than SMO with 53.2% versus 60.2%. Code-switching between Egyptian Arabic and English text is easiest to detect because Arabic and English are generally written in different character sets. It is more difficult to distinguish between Arabic dialects and MSA as these use the same character set, and most users of Arabic, especially Saudis and Egyptians, frequently mix MSA with their dialects. We also note that the MSA corpus used for training the MSA model may not represent MSA Facebook text well, being built from news websites. This paper also describes in detail the new Arabic corpora created for this research and our experiments.
Migration of treatment planning system using existing commissioned planning system
Authors: Tolakanahalli Ranjini , Paliwal Bhudatt , Tewatia Dinesh
Published: May 2020

Introduction:

Commissioning of a new planning system involves extensive data acquisition which can be onerous involving significant clinic downtime. This could be circumvented by extracting data from existing treatment planning system (TPS) to speed up the process.

Material and methods:

In this study, commissioning beam data was obtained from a clinically commissioned TPS (Pinnacle™) using Matlab™ generated Pinnacle™ executable scripts to commission an independent 3D dose verification TPS (Eclipse™). Profiles and output factors for commissioning as required by Eclipse™ were computed on a 50 × 50 × 50 cm3water phantom at a dose grid resolution of 2 mm3. Verification doses were computed and compared to clinical TPS dose profiles based on TG-106 guidelines. Standard patient plans from Pinnacle™ including intensity modulated radiation therapy and volumetric modulated arc therapy were re-computed on Eclipse™ TPS while maintaining the same monitor units. Computed dose was exported back to Pinnacle for comparison with the original plans. This methodology enabled us to alleviate all ambiguities that arise in such studies.

Results:

Profile analysis using in-house software showed that for all field sizes including small multi-leaf collimator-generated fields, >95% of infield and penumbra data points of Eclipse™ match Pinnacle™ generated and measured profiles with 2%/2 mm gamma criteria. Excellent agreement was observed in the penumbra regions, with >95% of the data points passing distance to agreement criteria for complex C-shaped and S-shaped profiles. Dose volume histograms and isodose lines of patient plans agreed well to within a 0·5% for target coverage.

Findings:

Migration of TPS is possible without compromising accuracy or enduring the cumbersome measurement of commissioning data. Economising time for commissioning such a verification system or for migration of TPS can add great QA value and minimise downtime.
Money Talks: Finance, War, and Great Power Politics in the Nineteenth Century
Authors: Shea Patrick E.
Published: May 2020

Finance is often considered a constraining or compelling force in war. This article examines an alternative role of finance in war, asserting that investors can inform states about adversarial intentions and resolve under certain conditions. This signaling mechanism can reduce information asymmetry between states and decrease the probability of conflict. In the context of these theoretical expectations, I examine the case of Austria and the Rothschild Bank in the nineteenth century. I find that instead of being a constraining force on Austrian foreign policy, the Rothschilds helped inform Austria and other European powers during interstate crises. The information provided by the Rothschilds helped Europe avert war in several cases during the nineteenth century.
