Aims. Our aim is to measure the masses and radii of the stars in a newly-discovered detached eclipsing binary system to a high precision (≈1%), enabling the system to be used for the calibration of free parameters in stellar evolutionary models.
Methods. Photometry from the Wide Angle Search for Planets (WASP) project was used to identify 1SWASP J063930.33-322404.8 (TYC 7091-888-1, WASP 0369-32 hereafter) as a detached eclipsing binary system with total eclipses and an orbital period of P = 11.66 days. Lightcurve parameters for WASP 0639-32 are obtained using the EBOP lightcurve model, with standard errors evaluated using a prayer-bead algorithm. Radial velocities were measured from 11 high-resolution spectra using a broadening function approach, and an orbit was fitted using SBOP. Observed spectra were disentangled and an equivalent width fitting method was used to obtain effective temperatures and metallicities for both stars. A Bayesian framework is used to explore a grid of stellar evolution models, where both helium abundance and mixing length are free to vary, and use observed parameters (mass, density, temperature, and metallicity) for each star to obtain the age and constrain the helium abundance of the system.
Results. The masses and radii are found to be M1 = 1.1544 ± 0.0043 M⊙, R1 = 1.833 ± 0.023 R⊙, and M2 = 0.7833 ± 0.0028 M⊙, R2 = 0.7286 ± 0.0081 R⊙ for the primary and secondary, respectively. The effective temperatures were found to be T1 = 6330 ± 50 K and T2 = 5400 ± 80 K for the primary and secondary star, respectively. The system has an age of 4.2−0.1+0.8 Gyr, and a helium abundance in the range 0.251–0.271.
Conclusions. WASP 0639-32 is a rare example of a well-characterised detached eclipsing binary system containing a star near the main-sequence turn-off point. This makes it possible to measure a precise age for the stars in this binary system and to estimate their helium abundance. Further work is needed to explore how this helium abundance estimate depends on other free parameters in the stellar models.

A Review of the Toxicity of Compounds Found in Herbal Dietary Supplements
Authors: Hudson Amy , Lopez Elizabeth , Almalki Ahmad J. , Roe Amy L. , Calderón Angela I. 
Published: April 2018

AbstractUse of herbal dietary supplements by the public is common and has been happening for centuries. In the United States, the Food and Drug Administration has a limited scope of regulation over marketed herbal dietary supplements, which may contain toxic botanical compounds that pose a public health risk. While the Food and Drug Administration has made efforts to prohibit the sale of unsafe herbal dietary supplements, numerous reports have proliferated of adverse events due to these supplements. This literature review investigates bioactive plant compounds commonly used in herbal dietary supplements and their relative toxicities. Using primarily the National Library of Medicine journal database and SciFinder for current reports, 47 toxic compounds in 55 species from 46 plant families were found to demonstrate harmful effects due to hepatic, cardiovascular, central nervous system, and digestive system toxicity. This review further contributes a novel and comprehensive view of toxicity across the botanical dietary market, and investigates the toxicity of the top ten botanical dietary supplements purchased in the United States of America to gauge the exposure risk of toxicity to the public. The criteria of measuring toxicity in this review (plant compound, family, quantity, and toxicity effects) across the entire market in the United States, with special attention to those supplements whose exposure to the consumer is maximal, provides a unique contribution to the investigation of botanical supplements.
Imaging Features of the Juvenile Inflammatory Arthropathies

Published: April 2018

AbstractWe discuss the imaging of several juvenile inflammatory arthropathies including juvenile idiopathic arthritis, juvenile systemic lupus erythematosus, juvenile scleroderma, juvenile dermatomyositis, and chronic recurrent multifocal osteomyelitis. Juvenile idiopathic arthritis is the most common autoimmune chronic systemic disease of connective tissue in children. The remaining systemic juvenile connective tissue diseases are rare. However, they require early diagnosis and initiation of treatment to prevent injury, not only to the musculoskeletal system but also to the internal organs, and even death. Imaging of juvenile inflammatory arthropathies has relied for years on radiography. Recent advances in disease-modifying drugs have led to a greater emphasis on the detection of early inflammation not evident on plain radiography. Ultrasound examination allows for the early recognition of the disease process in the soft tissues. Magnetic resonance imaging detects early inflammatory changes involving the soft tissues, the subcortical bone of peripheral joints, the spine, and entheses.

Published: April 2018

Objective To review the strengths, limitations, and new insights in the anatomy and magnetic resonance imaging (MRI) features of active and structural lesions of sacroiliitis in spondyloarthritis.
Discussion MRI plays a key role in the diagnosis and follow-up of sacroiliitis in spondyloarthritis. MRI of the sacroiliac joints in affected patients may show active lesions such as bone marrow edema, capsulitis, enthesitis, or synovitis as well as structural changes such as erosion, fat infiltration, sclerosis, backfill, and ankylosis. Active lesions of sacroiliitis on MRI are particularly important for the diagnosis and assessment of ongoing active inflammation. Structural lesions increasingly gain importance for diagnosis and follow-up.
Conclusion Active lesions remain the hallmark for assessment of inflammation in sacroiliitis. Structural lesions increasingly play a role in the diagnosis of spondyloarthritis.
Anterior Chest Wall in Axial Spondyloarthritis: Imaging, Interpretation, and Differential Diagnosis
Authors: Jans Lennart , Jurik Anne , Sudoł-Szopińska Iwona , Schueller-Weidekamm Claudia , Eshed Iris , Rennie Winston 
Published: April 2018

AbstractAnterior chest wall (ACW) inflammation is not an uncommon finding in patients with axial spondyloarthritis (ax-SpA) and reportedly occurs in 26% of these patients. Radiologists may only be familiar with spinal and peripheral joint imaging, possibly due to the inherent challenges of ACW imaging on some cross-sectional imaging modalities. Knowledge of relevant joint anatomy and the location of sites of inflammation allows the interpreting radiologist to better plan appropriate imaging tests and imaging planes. Accurate assessment of disease burden, sometimes in the absence of clinical findings, may alert the treating rheumatologist, allowing a better estimation of disease burden, increased accuracy of potential imaging scoring systems, and optimize assessment and response to treatment. This article reviews salient anatomy and various imaging modalities to optimize diagnosis, important differential diagnoses, and the interpretation of ACW imaging findings in ax-SpA.

Published: April 2018

ResumenLas fracturas de platillos tibiales son lesiones complejas que incluyen una variedad de patrones morfológicos cada vez mejor caracterizados en la literatura. Históricamente, los esquemas de clasificación se han basado en evaluar los rasgos de fractura en el plano frontal y las técnicas quirúrgicas en lograr la fijación de esos fragmentos, sin tomar en consideración el compromiso óseo que ocurre en la región posterior de los platillos tibiales. Con el advenimiento de la clasificación columnar basada en tomografía computada, se han logrado desarrollar estrategias de fijación optimizada, dando cada vez más relevancia a la columna posterior. Este artículo realiza una revisión extensa de la literatura, otorgando los fundamentos quirúrgicos que explican la importancia del tratamiento específico de la columna posterolateral y posteromedial, con el fin de restablecer la biomecánica normal de la rodilla y el razonamiento quirúrgico de las diversas vías de abordaje específicas para una reducción y osteosíntesis satisfactoria de esos fragmentos.
Early Autologous Blood-Patch Pleurodesis versus Conservative Management for Treatment of Secondary Spontaneous Pneumothorax
Authors: Ibrahim Islam , Elaziz Montaser , El-Hag-Aly Mohammed 
Published: April 2018

Background Autologous blood-patch pleurodesis has been effectively utilized as a treatment option for the condition of secondary spontaneous pneumothorax (SSP). Moreover, it can be used with persistent air leak, with or without residual air space. However, there have been no robust reports for the optimal timing for autologous blood-patch pleurodesis. The aim of this study is to compare early autologous blood-patch pleurodesis with conservative management of SSP.
Methods We conducted a randomized controlled study at the Menoufia University Hospital. A total of 47 patients with SSP were randomly allocated into two groups: group A (23 patients) received intrapleural instillation of 50 mL autologous blood 3 days after insertion of chest drain and group B (24 patients) managed conservatively. The duration required for air leak to seal, chest drainage duration, length of hospital stay, and the incidence of complications were compared and statistically analyzed.
Results The duration of air leak, duration to drain removal, and length of hospital stay were all significantly shorter in group A than in group B.
Conclusion Early intrapleural instillation of autologous blood is successful in sealing air leak in patients with SSP with persistent air leak, who are not fit or not willing to undergo surgery. It is superior to conservative treatment or late instillation of autologous blood, even if their lungs are not fully expanded.
Transfusionsmedizinische Versorgung von Patienten nach allogener Blutstammzelltransplantation
Authors: Hölig Kristina , Rosner Andrea 
Published: April 2018

ZusammenfassungIm Rahmen einer allogenen Blutstammzelltransplantation kommt es häufig zu immunhämatologischen Phänomenen, die im Rahmen der Diagnostik und der supportiven Hämotherapie berücksichtigt werden müssen. Durch Diskrepanzen der AB0-Merkmale von Spender und Empfänger können verschiedene Komplikationen auftreten. Die wesentlichsten sind ein verzögertes Engraftment der Erythropoese nach majorinkompatibler Transplantation (sogenannte Pure-red-Cell-Aplasie [PRCA]) und die verzögerte Hämolyse durch Aktivierung von minorinkompatiblen Lymphozyten im Transplantat, das sogenannte Passenger-Lymphocyte-Syndrom (PLS). Durch ein gezieltes immunhämatologisches Monitoring der Patienten können diese Phänomene zeitgerecht erkannt und adäquat therapiert werden. Ein Wechsel im Bereich des Rhesusantigens D ist ebenfalls bei der Hämotherapie allogen transplantierter Patienten zu berücksichtigen, verursacht allerdings nur selten Komplikationen. Hinsichtlich der Thrombozytenversorgung sollte rechtzeitig vor Konditionierungsbeginn eine gezielte Diagnostik von Immunisierungen gegen HLA- (humane Leukozytenantigene) und plättchenspezifische Antigene erfolgen, um die Thrombozytenversorgung mit ausgewählten Spendern in der Aplasiephase zuverlässig gewährleisten zu können. Bei sehr breit und hochtitrig immunisierten Patienten kann eine Immunsuppression mit Rituximab und Immunadsorption vor Transplantation die Inkremente nach Thrombozytensubstitution verbessern und im Falle von einem HLA-Mismatch des Transplantats auch das Engraftment unterstützen.
Cognitive underpinnings of nationalistic ideology in the context of Brexit
Authors: Zmigrod Leor , Rentfrow Peter J. , Robbins Trevor W. 
Published: April 2018

Significance
Belief in rigid distinctions between the nationalistic ingroup and outgroup has been a motivating force in citizens’ voting behavior, as evident in the United Kingdom’s 2016 EU referendum. We found that individuals with strongly nationalistic attitudes tend to process information in a more categorical manner, even when tested on neutral cognitive tasks that are unrelated to their political beliefs. The relationship between these psychological characteristics and strong nationalistic attitudes was mediated by a tendency to support authoritarian, nationalistic, conservative, and system-justifying ideologies. This suggests flexible cognitive styles are related to less nationalistic identities and attitudes.
Non-Formality of Planar Configuration Spaces in Characteristic 2
Authors: Salvatore Paolo 
Published: April 2018

AbstractWe prove that the ordered configuration space of four points or more in the plane has a nonformal singular cochain algebra in characteristic 2. This is proved by constructing an explicit nontrivial obstruction class in the Hochschild cohomology of the cohomology ring of the configuration space, by means of the Barratt–Eccles–Smith simplicial model. We also show that if the number of points does not exceed its dimension then a Euclidean configuration space is intrinsically formal over any ring.
Colonial Capitalism and the Dilemmas of Liberalism
Authors: Ince Onur Ulas 
Published: April 2018

Abstract
This book analyzes the relationship between liberalism and empire from the perspective of political economy. It investigates the formative impact of “colonial capitalism” on the historical development of British liberal thought between the late seventeenth and early nineteenth centuries. It argues that liberalism as a political language developed through early modern debates over the contested meanings of property, exchange, and labor, which it examines respectively in the context of colonial land appropriations in the Americas, militarized trading in South Asia, and state-led proletarianization in Australasia. The book contends that the British Empire could be extolled as the “empire of liberty”—that is, the avatar of private property, free trade, and free labor—only on the condition that its colonial expropriation, extraction, and exploitation were “disavowed” and dissociated from the increasingly liberal conception of its capitalist economy. It identifies exemplary strategies of disavowal in the works of John Locke, Edmund Burke, and Edward G. Wakefield, who, as three liberal intellectuals of empire, attempted to navigate the ideological tensions between the liberal self-image of Britain and the violence that shaped its imperial economy. Challenging the prevalent tendency to study liberalism and empire around an abstract politics of universalism and colonial difference, the book discloses the ideological contradictions internal to Britain’s imperial economy and their critical influence on the formation of liberalism. It concludes that the disavowal of the violence constitutive of capitalist relations in the colonies has been crucial for crafting a liberal image for Anglophone imperialism and more generally for global capitalism.
An Educational Implementation Process Staff Survey: Lessons Learned
Authors: Delmore Barbara , Kent Martha 
Published: April 2018

ABSTRACT

OBJECTIVE:
To evaluate the education process for the effective use of the Munro Pressure Ulcer Risk Assessment Scale by practicing perioperative staff at an urban tertiary medical center. Given that pressure injury formation is tied to the surgical process, there is a need for a pressure injury risk assessment scale that addresses the uniqueness of the perioperative process.

METHODS:
Participants were staff who worked in the surgical admissions area, the main operating room, and the main postanesthesia care unit. The authors’ facility was 1 of 8 participants in a multisite study. Each site was required to educate staff using standard written instructions and an instructional webinar. However, sites were also encouraged to consider any other methods that would successfully engage the staff in the learning process. After the education process, staff were surveyed and asked to evaluate the educational interventions.

MAIN RESULTS:
Findings indicated that the staff did not prefer written instructions alone but rather preferred a combination of different learning modalities and media to assist them in using the Munro Scale effectively.

CONCLUSIONS:
This article discusses the strategies required to engage staff in the implementation process of this scale, the barriers encountered during this implementation, and the implications for perioperative nursing using this scale. The lessons learned from conducting this research provided insight into engaging and educating the adult learner in a new process.

(Abstracted from Am J Epidemiol 2017;186(10):1131–1139)
Although there exists a plethora of evidence on the adverse adult health effects of negative macroeconomic change, little is known about the effects of macroeconomic change on birth outcomes. This association is inherently difficult to discern, given the lack of state- and time-specific data and the simultaneous effects of economic conditions on fetal health and economic conditions on who is born (ie, selection). Economic conditions prior and during pregnancy may affect women's choices to conceive, declines in fertility, spontaneous pregnancy loss, and elective abortion.

Study Design.
Retrospective matched cohort analysis.

Objective.
To compare the accuracy of S2 alar-iliac (S2AI) screw placement by robotic guidance versus free hand technique.

Summary of Background Data.
Spinopelvic fixation utilizing S2AI screws provides optimal fixation across the lumbosacral junction allowing for solid fusion, especially in long segment fusion constructs. Traditionally, S2AI screw placement has required fluoroscopic guidance for accurate screw placement. Herein, we present the first series comparing a free hand and robotic-guided technique for S2AI screw placement.

Methods.
Sixty-eight consecutive patients who underwent S2AI screw placement by either a free hand or robotic technique between 2015 and 2016 were reviewed. Propensity score-matching was utilized to control for preoperative characteristic imbalances. Screw position and accuracy were evaluated using three-dimensional manipulation of computed tomography scan reconstructions from intraoperative O-arm imaging.

Results.
A total of 51 patients (105 screws) were matched, 28 (59 screws) in the free hand group (FHG) and 23 (46 screws) in the robot group (RG). The mean age in the FHG and RG were 57.9 ± 14.6 years and 61.6 ± 12.0 years (P = 0.342), respectively. The average caudal angle in the sagittal plane was significantly larger in the RG (31.0 ± 10.0° vs. 25.7 ± 8.8°, P = 0.005). There was no difference between the FHG and RG in the horizontal angle, measured in the axial plane using the posterior superior iliac spine (PSIS) as a reference (41.1 ± 8.1° vs. 42.8 ± 6.6°, P = 0.225), or the S2AI to S1 screw angle (9.4 ± 7.0° vs. 11.3 ± 9.9°, P = 0.256), respectively. There was no difference in the overall accuracy between FHG and RG (94.9% vs. 97.8%, P = 0.630). Additionally, there were no significant intraoperative neurovascular or visceral complications associated with S2AI screw placement.

Conclusion.
Free hand and robotic-guided S2AI screw placement both prove to be safe, accurate, and reliable techniques for achieving spinopelvic fixation.
