Functional consequences of flower curvature, orientation and perch position for nectar feeding by sunbirds
Authors: Johnson Steven D , Kiepiel Ian , Robertson Alastair W 
Published: September 2020

AbstractMutualisms between nectarivorous birds and the plants they pollinate are functionally diverse. Nectarivorous birds which hover while feeding (the majority of hummingbirds) tend to have straight bills, while those that perch while feeding (some hummingbirds and almost all passerine nectarivores) tend to have decurved bills. Sunbirds typically use their curved bills to feed in an arc from a perching position and we thus predicted that they would prefer, and feed most efficiently on, flowers that are curved towards a perching position. To test this, we examined the responses of sunbirds to model flowers differing in curvature (straight or curved), orientation (facing upwards or downwards), and availability of a top perch (present or absent). Birds did not show preferences among model flower types in terms of number of landings to feed or number of probes. In general they preferred to use perches above model flowers, particularly those that curved upwards, but they tended to perch below model flowers that curve downwards and in such cases also took the least time to insert their bills. These results are consistent with the idea that perching birds with curved beaks will feed most efficiently from flowers that are curved towards the perching position. We discuss the implications of these results for the evolution of floral architecture, including provision of perches.
Ablation for idiopathic left ventricular tachycardia in a patient with double outlet right ventricle who underwent Fontan operation: a case report

Published: September 2020

Abstract

Background
The incidence of ventricular tachycardia (VT) in patients following Fontan operation is reported as 3.5%. Furthermore, in patients with repaired double outlet right ventricle (DORV), scar-related VT and outflow tract VT have been reported; however, Purkinje-related VT has not previously been reported. In this report, we present the case of idiopathic left VT (ILVT) in a patient with DORV who underwent Fontan operation.

Case summary
A 31-year-old man was diagnosed as having DORV with complete atrioventricular defect at birth. When he was 17 years old, he underwent surgical repair, including extracardiac Fontan operation and common atrioventricular valve replacement. Five years later, VT was detected. Since some medications were ineffective in suppressing VT, he was referred to our hospital for definitive treatment. Ventricular tachycardia was induced by atrial and ventricular programmed electrical stimulations. The mechanism of the VT was determined to be re-entry. The earliest activation site was located at the mid-inferior septum of the hypoplastic left ventricle, in which Purkinje potentials were observed before the local ventricular electrogram. Radiofrequency catheter ablation (RFCA) was performed at this site to eliminate VT.

Discussion
Most VTs originate from surgical scars in patients with congenital heart disease. Catheter ablation was feasible in scar-related VT. To the best of our knowledge, this is the first report of ILVT treated successfully with RFCA in a DORV patient who had undergone Fontan operation.
Managing acute pulmonary embolism in primary care in a patient declining emergency department transfer: a case report
Authors: Vinson David R , Isaacs Dayna J , Johnson Elizabeth J 
Published: September 2020

AbstractBackgroundFor patients with acute pulmonary embolism (PE) diagnosed in the primary care setting, transfer to a higher level of care, like the emergency department, has long been the convention. Evidence is growing that outpatient management, that is, care without hospitalization, is safe, effective, and feasible for selected low-risk patients with acute PE. Whether outpatient care can be provided entirely in the primary care setting has not been well-studied. We report a case of outpatient management of a low-risk patient with acute PE without emergency department transfer.Case summaryA 74-year-old woman with a history of recent surgery and immobilization presented to a primary care physician with 10 days of mild, non-exertional pleuritic chest pain. Her D-dimer concentration was elevated. Computed tomography pulmonary angiography identified a lobar embolus without right ventricular dysfunction. She declined emergency department transfer but was classified as low risk (class II) on the PE Severity Index and met the criteria of the European Society of Cardiology (ESC) for outpatient care. Her physician provided comprehensive clinic-based PE management, discharging her to home with education, anticoagulation, and close follow-up. She completed her 3-month treatment course without complication.DiscussionThis case describes patient-centred, comprehensive, outpatient PE management in the primary care setting for a woman meeting explicit ESC outpatient criteria. This case illustrates the elements of care that clinics can put in place to facilitate PE management without having to transfer eligible low-risk patients to a higher level of care.
Examining Health and Wealth Correlates of Perceived Financial Vulnerability: A Normative Study
Authors: Lichtenberg Peter A , Paulson Daniel , Han S Duke 
Published: September 2020

Abstract

Background and Objectives
Age-associated financial vulnerability was introduced because it was increasingly recognized that cognitively intact older adults experienced changes that rendered them financially vulnerable. In this study, we attempt to apply the construct of Age-Associated Financial Vulnerability to a measure of Perceived Financial Vulnerability and whether this perceived vulnerability is predicted by risk factors from the 4 categorical domains used to define Age-Associated Financial Vulnerability’s impact.

Research Design and Methods
This study was part of the Health and Retirement Study (HRS) survey in 2018. The survey contained 7 experimental module items of Perceived Financial Vulnerability. One thousand three hundred fourteen participants completed the Perceived Financial Vulnerability measure. The sample was drawn from Waves 13 and 14 of the HRS (2016 and 2018, respectively). The measurement of Perceived Financial Vulnerability was developed on the basis of 7 questions assessing financial awareness and psychological vulnerability items regarding personal finance that were included in the 2018 HRS data collection. Predictors included measures of cognition, function/health, depression, and wealth. Predictor measures from 2016 were regressed on 2018 Perceived Financial Vulnerability scores.

Results
Six items of Perceived Financial Vulnerability had psychometric properties acceptable for a new measure. Responses revealed variability in Perceived Financial Vulnerability. Overall, 18% of variance was accounted for and measures from cognition, depression, assets, and functional abilities were all unique and significant predictors.

Discussion and Implications
This study represents both a conceptual and empirical contribution to our understanding of older adult’s perceptions of financial vulnerability. The high levels of Perceived Financial Vulnerability found in this normative sample underscore the importance of context in understanding people’s economic behaviors. For instance, more than one half of the sample indicated that they wished they had someone to talk to about their finances. This desire to talk with others is normative and yet often underappreciated.
Securing the nation through the politics of sexual violence: tracing resonances between Delhi and Cologne
Authors: Holzberg Billy , Raghavan Priya 
Published: September 2020

Abstract
Postcolonial and black feminist scholars have long cautioned against the dangerous proximity between the politics of sexual violence and the advancement of nationalist and imperial projects. In this article, we uncover what it is in particular about efforts to address sexual violence that makes them so amenable to exclusionary nationalist projects, by attending to the political aftermaths of the rape of Jyoti Singh in Delhi in 2012, and the cases of mass sexual abuse that took place during New Year's Eve in Cologne in 2015. Tracing the nationalist discourses and policies precipitated in their wake, we demonstrate how across both contexts, the response to sexual violence was ultimately to augment the securitizing power and remit of the state—albeit through different mechanisms, and while producing different subjects of/for surveillance, control and regulation. We highlight how in both cases it is through contemporary resonances of a persistent (post)colonial echo—which enmeshes the normative female body with the idea of the nation—that sexual abuse becomes an issue of national security and the politics of sexual violence becomes tethered to exclusionary nationalisms. Revealing the more general, shared, rationalities that bind the nation to the normative female body while attending to the located political reverberations that make this entanglement so affectively potent in the distinct contexts of India and Germany helps distinguish and amplify transnational and intersectional feminist approaches to sexual violence that do not so readily accommodate nationalist ambitions.
What are the endovascular options and outcomes for repair of ascending aortic or aortic arch pathology?
Authors: Sharma Varun J , Prakash Minesh , Lin Zaw , Lo Casey 
Published: September 2020

Summary
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was ‘in patients with ascending aortic or aortic arch disease what are the outcomes with endovascular repair in terms of survival, complications and reintervention?’ Altogether 585 papers were found using the reported search, of which 9 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We found that the endovascular operative techniques with the greatest evidence were ascending aortic chimney grafts (AACs), branched thoracic endovascular aortic repair (bTEVAR) aortic grafts and fenestrated TEVAR (fTEVAR) aortic grafts. The best evidence available were small case-series or retrospective cohort studies (n &lt; 100), with 1 systematic review, at a short follow-up period (range 0–5 years). Intraoperatively, these techniques have a high technical success rate (84–100%). We found rates of endoleak comparable between AAC (7.4–16%) and bTEVAR/fenestrated TEVAR (11.1–21.4%). Stroke rates are higher in bTEVAR (3.1–42% vs 1–26% in AACs), attributed to more proximal pathology and technically challenging procedures. Following the immediate postoperative period, the 30-day mortality is 0–10.8% and patency is 97–100%. Stroke and reintervention rates remain higher in the bTEVAR group (3.1–42.0% and 0.5–33.3%) compared to the AAC group (1.0–11.1% and 6.7–16.7%). The 3- and 5-year survival ranges from 59% to 90%, but is driven by non-aortic pathology in a high-risk population; 3-year freedom from aortic death is 93–97%. Patency is 97–100% at up to 3 years, conformation and supra-aortic occlusions thereafter remain unknown. We conclude that AACs, bTEVARs and fenestrated TEVARs are safe endovascular options in high-risk elective patients, with results comparable to open or hybrid repair. They remain unverified in acute settings or in patients fit for open intervention.
Midterm varicose vein recurrence rates after endovenous laser ablation: comparison of radial fibre and bare fibre tips
Authors: Abud Burcin , Kunt Ayse Gul 
Published: September 2020

Abstract

OBJECTIVES
We evaluated and compared midterm recurrence results of our patients with great saphenous vein insufficiency who were treated with a 1470-nm diode laser using 2 different types of fibre catheter kits.

METHODS
A total of 61 consecutive patients were treated between 2013 and 2014 with a bare fibre (BF) tip (BF group) and 60 consecutive patients were treated with a radial fibre (RF) tip (RF group) from 2014 to 2016. First-year venous clinical severity scores (VCSSs) were compared with VCSS before endovenous laser ablation and at the first-month follow-up. Patients were examined for recurrence and classified according to the system developed by Stonebridge.

RESULTS
There was no significant difference between the 2 groups in terms of VCSS. Examination with Doppler ultrasonography showed no recurrence in the RF group, whereas recurrences were detected in 6 patients in the BF group, which was statistically significant (P = 0.028). All of the recurrences were type 1b (incompetent tributaries) varicose vein recurrences. The VCSS of the patients with recurrence were the same as the scores of patients without recurrence (0.5 ± 0.55).

CONCLUSIONS
Varicose vein recurrence was more often seen in the BF group than in the RF group. Recanalization-induced and neovascularization-induced recurrences were not found in either group. Saphenofemoral side branch-induced recurrence was more significant in the group treated with the BF tip.
Intrinsic phytase in hybrid rye increases the digestibility of phosphorus in corn and soybean meal in diets fed to growing pigs

Published: September 2020

AbstractAn experiment was conducted to test the hypothesis that inclusion of hybrid rye in diets containing corn and soybean meal (SBM) without or with microbial phytase improves the apparent total tract digestibility (ATTD) and the standardized total tract digestibility (STTD) of P because of the intrinsic phytase activity in hybrid rye. Forty-eight growing barrows (initial body weight: 39.5 ± 7.7 kg) were allotted to six diets. A basal diet containing corn and SBM; a rye-based diet; and a diet containing corn, SBM, and rye were formulated. Each diet was formulated without and with microbial phytase (500 units/kg of diet) for a total of six diets. Fecal samples were collected for 4 d following a 5-d adaptation period according to the marker-to-marker procedure. Results indicated that no interactions between diets and concentration of phytase were observed for any of the response criteria measured. The ATTD and STTD of P and the ATTD of Ca differed (P &lt; 0.05) among diets, but regardless of diet, the concentration of P in feces was reduced (P &lt; 0.05) by adding microbial phytase to the diets. As a consequence, microbial phytase increased (P &lt; 0.05) ATTD and STTD of P, and the ATTD of Ca was also increased (P &lt; 0.05) by the use of microbial phytase. Measured values for the ATTD and STTD of P in the diets containing corn, SBM, and hybrid rye without or with phytase were greater (P &lt; 0.05) than values that were predicted based on the ATTD and STTD of P for the corn–SBM and the hybrid rye diet. The observation that STTD predicted from the individual ingredients underestimated the STTD of P in the mixed diet indicates that the intrinsic phytase in hybrid rye resulted in increased digestibility of the P in the corn and SBM included in the corn–SBM–hybrid rye diet. In conclusion, microbial phytase increased the ATTD and STTD of P and the ATTD of Ca regardless of feed ingredients used in diets fed to pigs. In addition, the intrinsic phytase from hybrid rye increased the ATTD and STTD of P in corn and SBM.
Chronotopic information interaction: integrating temporal and spatial structure for historical indexing and interactive search
Authors: Adams Benjamin 
Published: September 2020

Abstract
Domain-based learning and research are important applications driving the development of exploratory search systems. A wealth of historical information about events from around the world resides within documents on the web, yet contemporary search engines do not take advantage of the closely integrated temporal and spatial information found within these web pages for indexing and design of search user interfaces. This gap limits the use of the web as a resource for historical and geohistorical information seeking. In this article, we propose chronotopic information interaction as a new interaction concept for web search that explicitly links temporal and spatial entities to keywords using a space–time grid index and a paired search user interface. The space–time grid index allows different modes of interaction between spatial, temporal, and keyword-based views in the search user interface. We demonstrate the use of the space–time grid index and chronotopic information interaction concept with the development of Pteraform, a prototype of a search engine that enables users to explore information in the English version of Wikipedia through a geohistorical lens.
Expectancy Theory of Motivation and Substance Use Treatment: Implications for Music Therapy
Authors: Yoes Marshall , Silverman Michael J 
Published: September 2020

Abstract
The existing literature indicates that motivation is an important predictor of treatment outcome for people with substance use disorders (SUD). Although researchers have found that music therapy can positively impact motivation for people with SUD, the music therapy and SUD literature base lack a theoretical understanding of motivation. Vroom’s expectancy theory of motivation (ETM) is an established theoretical framework positing that motivation depends on three relationships: expectancy, instrumentality, and valence. These relationships consist of four variables: effort, performance, reward, and preference. Based on these four variables, motivation depends on the expectation that an increase in effort will lead to improved performance, thus leading to a reward aligned with an individual’s preferences. The purpose of this paper is to apply Vroom’s ETM to music therapy and SUD clinical practice and research. We reviewed the existing literature addressing Vroom’s ETM within SUD treatment and created a model to depict how to apply Vroom’s ETM to music therapy clinical practice for people with SUD. Application of Vroom’s ETM may help music therapists understand and augment motivation for people with SUD, potentially leading to relapse prevention and recovery. Implications for clinical practice, limitations, and suggestions for future research are provided.

Abstract
Construction of sustainable high-performance structural materials is a core part of the key global sustainability goal. Many efforts have been made in this field; however, challenges remain in terms of lowering costs by using all-green basic building blocks and improving mechanical properties to meet the demand of practical applications. Here, we report a robust and efficient bottom-up strategy with micro/nanoscale structure design to regenerate an isotropic wood from natural wood particles as a high-performance sustainable structural material. Regenerated isotropic wood (RGI-wood) exceeds the limitations of the anisotropic and inconsistent mechanical properties of natural wood, having isotropic flexural strength of ∼170 MPa and flexural modulus of ∼10 GPa. RGI-wood also shows superior water resistance and fire retardancy properties to natural pine wood. Mass production of large sized RGI-wood and functional RGI-wood nanocomposites can also be achieved.

Abstract
We have investigated the status of the nuclear debris in the Unit-2 Nuclear Reactor of the Fukushima Daiichi Nuclear Power plant by the method called Cosmic Muon Radiography. In this measurement, the muon detector was placed outside of the reactor building, as was the case of the measurement for the Unit-1 Reactor. Compared to the previous measurements, the detector was down-sized, which made it possible for us to locate it closer to the reactor and to investigate the lower part of the fuel loading zone in particular. We identified the inner structures of the reactor such as the containment vessel, pressure vessel and other objects through the thick concrete wall of the reactor building. Furthermore, the observation showed existence of heavy material at the bottom of the pressure vessel, which can be interpreted as the debris of melted nuclear fuel dropped from the loading zone.
Large-scale survey reveals pervasiveness and potential function of endogenous geminiviral sequences in plants

Published: September 2020

Abstract
The family Geminiviridae contains viruses with single-stranded DNA genomes that have been found infecting a wide variety of angiosperm species. The discovery within the last 25 years of endogenous geminivirus-like (EGV) elements within the nuclear genomes of several angiosperms has raised questions relating to the pervasiveness of EGVs and their impacts on host biology. Only a few EGVs have currently been characterized and it remains unclear whether any of these have influenced, or are currently influencing, the evolutionary fitness of their hosts. We therefore undertook a large-scale search for evidence of EGVs within 134 genome and 797 transcriptome sequences of green plant species. We detected homologues of geminivirus replication-associated protein (Rep) genes in forty-two angiosperm species, including two monocots, thirty-nine dicots, and one ANITA-grade basal angiosperm species (Amborella trichopoda). While EGVs were present in the members of many different plant orders, they were particularly common within the large and diverse order, Ericales, with the highest copy numbers of EGVs being found in two varieties of tea plant (Camellia sinensis). Phylogenetic and clustering analyses revealed multiple highly divergent previously unknown geminivirus Rep lineages, two of which occur in C.sinensis alone. We find that some of the Camellia EGVs are likely transcriptionally active, sometimes co-transcribed with the same host genes across several Camellia species. Overall, our analyses expand the known breadths of both geminivirus diversity and geminivirus host ranges, and strengthens support for the hypothesis that EGVs impact the biology of their hosts.
