An evaluation of telehealth expansion in U.S. nursing homes
Authors: Alexander Gregory L , Powell Kimberly R , Deroche Chelsea B 
Published: September 2020

Abstract

Objective
This research brief contains results from a national survey about telehealth use reported in a random sample of U.S. nursing homes.

Methods and Materials
The sample includes nursing homes (N = 664) that completed surveys about information technology maturity, including telehealth use, beginning January 1, 2019, and ending August 4, 2020. A pre/post design was employed to examine differences in nursing home telehealth use for nursing homes completing surveys prior to and after telehealth expansion, on March 6, 2020. We calculated a cumulative telehealth score using survey data from 6 questions about extent of nursing home telehealth use (score range 0-42). We calculated proportions of nursing homes using telehealth and used logistic regression to look for differences in nursing homes based on organizational characteristics and odds ratios.

Results
Significant relationships were found between nursing home characteristics and telehealth use, and specifically, larger metropolitan homes reported greater telehealth use. Ownership had little effect on telehealth use. Nursing homes postexpansion used telehealth applications for resident evaluation 11.24 times more (P &lt; .01) than did nursing homes pre-expansion.

Discussion
Administrators completing our survey reported a wide range of telehealth use, including approximately 16% having no telehealth use and 5% having the maximum amount of telehealth use. Mean telehealth use scores reported by the majority of these nursing homes is on the lower end of the range.

Conclusions
One solution for the current pandemic is to encourage the proliferation of telehealth with continued relaxed regulations, which can reduce isolation and preserve limited resources (eg, personal protective equipment) while maintaining proper distancing parameters.
A digital health profile & maturity assessment toolkit: cocreation and testing in the Pacific Islands
Authors: Liaw Siaw-Teng , Zhou Rui , Ansari Sameera , Gao Jun 
Published: September 2020

Abstract

Introduction
Countries need to determine their level of digital health capability maturity to assess and mobilize their knowledge, skills, and resources to systematically develop, implement, evaluate, scale up and maintain large-scale implementations of standards-based interoperable digital health tools.

Objective
Develop a Digital Health Profile and Maturity Assessment Toolkit (DHPMAT) to assist Pacific Island Countries (PICs) to harness digital tools to support national health priorities.

Materials and Methods
A literature review guided the development of the conceptual framework to underpin the DHPMAT. Key informants collaborated to collect key digital health features and indicators to inform their country’s digital health maturity assessment. The DHPMAT was tested with country stakeholders at a Pacific Health Information Network workshop in 2019.

Results
A comprehensive list of indicators to describe country digital health profiles (DHP). A digital health maturity assessment tool that uses criteria codeveloped with country stakeholders to assess essential digital health foundations and quality improvement. DHPs created and maturity assessed and packaged into individualized DHPMATs for 13 PICs. PIC users perceived the DHPMAT as useful, especially the congruence with the 2017 WHO WPRO Regional Strategy but noted a “cognitive overload” from a plethora of complex digital health toolkits.

Conclusions
The cocreation approach optimized currency, accuracy, and appropriateness of information in the DHP, understanding, and use of the DHPMAT to facilitate informed iterative discussion by PICs on their digital health maturity to harness digital tools to strengthen country health systems. The DHPMAT can rationalize the choice and use of existing tools and reduce cognitive overload.
Xylanase supplementation in corn-based swine diets: a review with emphasis on potential mechanisms of action
Authors: Petry Amy L , Patience John F 
Published: September 2020

AbstractCorn is a common energy source in pig diets globally; when financially warranted, industrial corn coproducts, such as corn distiller’s dried grains with solubles (DDGS), are also employed. The energy provided by corn stems largely from starch, with some contribution from protein, fat, and non-starch polysaccharides (NSP). When corn DDGS are used in the diet, it will reduce starch within the diet; increase dietary protein, fat, and NSP levels; and alter the source profile of dietary energy. Arabinoxylans (AXs) comprise the majority of NSP in corn and its coproducts. One strategy to mitigate the antinutritive effects of NSP and improve its contribution to energy is by including carbohydrases within the diet. Xylanase is a carbohydrase that targets the β-1,4-glycosidic bonds of AX, releasing a mixture of smaller polysaccharides, oligosaccharides, and pentoses that could potentially be used by the pig. Xylanase is consistently effective in poultry production and moderately consistent in wheat-based swine diets, but its efficacy in corn-based swine diets is quite variable. Xylanase has been shown to improve the digestibility of various components of swine-based diets, but this seldom translates into an improvement in growth performance. Indeed, a review of xylanase literature conducted herein suggests that xylanase improves the digestibility of dietary fiber at least 50% of the time in pigs fed corn-based diets, but only 33% and 26% of the time was there an increase in average daily gain or feed efficiency, respectively. Intriguingly, there has been an abundance of reports proposing xylanase alters intestinal barrier integrity, inflammatory responses, oxidative status, and other health markers in the pig. Notably, xylanase has shown to reduce mortality in both high and low health commercial herds. These inconsistencies in performance metrics, and unexpected health benefits, warrant a greater understanding of the in vivo mechanism(s) of action (MOA) of xylanase. While the MOA of xylanase has been postulated considerably in the literature and widely studied in in vitro settings, in wheat-based diets, and in poultry, there is a dearth of understanding of the in vivo MOA in pigs fed corn-based diets. The purpose of this review is to explore the role of xylanase in corn-based swine diets, discuss responses observed when supplemented in diets containing corn-based fiber, suggest potential MOA of xylanase, and identify critical research gaps.
Morphology of gastric mills and mandibles of New Guinean parastacid crayfishes, with comparisons with other Astacidea (Decapoda)
Authors: Kawai Tadashi , Patoka Jiří 
Published: September 2020

Abstract
Knowledge of the morphological features of crayfishes native to New Guinea is limited in many cases, the internal morphology, gastric mills, and mandibles of six species of Cherax species (Decapoda: Astacidea: Parastacidae) from this island were described and illustrated. The measurements were compared with those of parastacid crayfish from Madagascar and New Zealand, with Enoplometopoidea from coral reefs, and Nephropidea from deep sea. Characters peculiar to the family Parastacidae were found both in gastric mills and mandibles, and differences between the morphology of mandibles in freshwater and marine species from the infraorder Astacidea were found. Relationships between functional morphology and feeding behaviour were discussed.
Decentralized Finance
Authors: Zetzsche Dirk A , Arner Douglas W , Buckley Ross P 
Published: September 2020

ABSTRACT
DeFi (‘decentralized finance’) has joined FinTech (‘financial technology’), RegTech (‘regulatory technology’), cryptocurrencies, and digital assets as one of the most discussed emerging technological evolutions in global finance. Yet little is really understood about its meaning, legal implications, and policy consequences. In this article we introduce DeFi, put DeFi in the context of the traditional financial economy, connect DeFi to open banking, and end with some policy considerations. We suggest that decentralization has the potential to undermine traditional forms of accountability and erode the effectiveness of traditional financial regulation and enforcement. At the same time, we find that where parts of the financial services value chain are decentralized, there will be a reconcentration in a different (but possibly less regulated, less visible, and less transparent) part of the value chain. DeFi regulation could, and should, focus on this reconcentrated portion of the value chain to ensure effective oversight and risk control. Rather than eliminating the need for regulation, in fact DeFi requires regulation in order to achieve its core objective of decentralization. Furthermore, DeFi potentially offers an opportunity for the development of an entirely new way to design regulation: the idea of ‘embedded regulation’. Regulatory approaches could be built into the design of DeFi, thus potentially decentralizing both finance and its regulation, in the ultimate expression of RegTech.
Interrogating Genomic-Scale Data to Resolve Recalcitrant Nodes in the Spider Tree of Life

Published: September 2020

Abstract
Genome-scale data sets are converging on robust, stable phylogenetic hypotheses for many lineages; however, some nodes have shown disagreement across classes of data. We use spiders (Araneae) as a system to identify the causes of incongruence in phylogenetic signal between three classes of data: exons (as in phylotranscriptomics), noncoding regions (included in ultraconserved elements [UCE] analyses), and a combination of both (as in UCE analyses). Gene orthologs, coded as amino acids and nucleotides (with and without third codon positions), were generated by querying published transcriptomes for UCEs, recovering 1,931 UCE loci (codingUCEs). We expected that congeners represented in the codingUCE and UCEs data would form clades in the presence of phylogenetic signal. Noncoding regions derived from UCE sequences were recovered to test the stability of relationships. Phylogenetic relationships resulting from all analyses were largely congruent. All nucleotide data sets from transcriptomes, UCEs, or a combination of both recovered similar topologies in contrast with results from transcriptomes analyzed as amino acids. Most relationships inferred from low-occupancy data sets, containing several hundreds of loci, were congruent across Araneae, as opposed to high occupancy data matrices with fewer loci, which showed more variation. Furthermore, we found that low-occupancy data sets analyzed as nucleotides (as is typical of UCE data sets) can result in more congruent relationships than high occupancy data sets analyzed as amino acids (as in phylotranscriptomics). Thus, omitting data, through amino acid translation or via retention of only high occupancy loci, may have a deleterious effect in phylogenetic reconstruction.
Chemical Elements in Electronic Cigarette Solvents and Aerosols Inhibit Mitochondrial Reductases and Induce Oxidative Stress

Published: September 2020

Abstract

Introduction
Chemical elements and their toxicity were evaluated in electronic cigarette (EC) solvents, fluids, and aerosols.

Aims and Methods
Element identification and quantification in propylene glycol (PG), glycerin (G), refill fluids before and after use, and aerosols was done using inductively coupled plasma optical emission spectrometry. Cytotoxicity and oxidative stress were evaluated using in vitro assays.

Results
Seven elements were present in PG, G, and popular refill fluids, and they transferred to aerosols made with ECs. Selenium was in all products (0.125–0.292 mg/L), while arsenic, aluminum, and tin were frequently in solvent and refill fluid samples at lower concentrations. Iron, chromium, copper, nickel, zinc, and lead were only detected in fluid after EC use, indicating they came from heated atomizers. Elements transferred most efficiently to aerosols made with second-/third-generation ECs. Of the elements in fluid, selenium and arsenic were the most cytotoxic to human bronchial epithelial cells (BEAS-2B) and pulmonary fibroblasts in the 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide assay. Selenium increased superoxide production in mitochondria and nucleoli and elevated selenoprotein H in nucleoli of BEAS-2B cells at concentrations found in EC aerosols (10 nM or 0.002 mg/L).

Conclusions
Elements in EC aerosols came from both e-fluids and atomizing units. Within second-/third-generation products, transfer became more efficient as power increased. In vitro responses occurred at concentrations of selenium found in some EC aerosols. Human exposure to chemical elements in ECs could be reduced by regulating (decreasing) allowable EC power and by improving the purity of PG and G.

Implications
PG, G, refill fluids, and e-fluids contained potentially toxic chemical elements that transferred to aerosols. Transfer was more efficient in second- and third-generation EC products and increased as power increased. Selenium and arsenic were the most cytotoxic of the elements tested in the 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide assay. Selenium tetrachloride-induced oxidative stress in BEAS-2B cells, but not in human pulmonary fibroblasts. All fluids contained selenium above the concentration that induced oxidative stress in human bronchial epithelial cells. Selenium increased superoxide in mitochondria and nucleoli and increased selenoprotein H, a redox responsive DNA-binding protein that is upregulated by superoxide and an indicator of nucleolar stress. EC users are exposed to elements in aerosols, which may with chronic exposure contribute to diseases associated with oxidative stress.

AbstractContextGlobally, the use of labels or signage targeting SSBs remains in its infancy and there is limited evidence available regarding its ability to decrease purchase and consumption of SSBs.ObjectiveThis systematic review aimed to synthesize the evidence on the effect of sugar- or health-related sugar-sweetened beverage (SSB) warning labels or signage on knowledge, attitudes, and beliefs, and SSB purchase and consumption.Data sourcesNine databases – Ovid Medline, Emerald Insight, Scopus, Informit, Business Source Complete, CINAHL, Global Health, PsychINFO, and SocIndex – were searched along with grey literature from inception to December 2019. The PRISMA guidelines were applied for reporting this systematic review.Study SelectionStudies examining the impact of front of pack (FOP) labels and/or point of sale (POS) signage highlighting added sugar content or its health risks were included.Data extractionTwo authors independently extracted data on items, including study details, study design, population characteristics, intervention label details (type, duration, and settings), and outcomes measures. The Effective Public Health Practice Project tool was used to assess the study quality.Data analysisFindings were synthesized narratively.ResultsTwenty-one studies published between 1992 and 2019 were included. Of these, 16 studies examined the impact of FOP labels and 5 studies examined the impact of POS signage. Both FOP labels and POS signage were associated with improved health knowledge, attitudes, and beliefs regarding SSBs and reduced SSB purchases. Warning labels with diet-related health consequences were found to be particularly effective. Overall quality of studies was assessed as mixed.ConclusionHealth- or sugar-related FOP labels and POS signage for SSBs are promising public health measures and may improve consumers’ health behaviors toward reduced SSB purchase and consumption.

Published: September 2020

Abstract
Bi shielding has been used for the protection of radiosensitive organs during computed tomography (CT) for 20 years. In 2017, American Association of Physicists in Medicine recommended against Bi shielding due to its degrading effects on image quality. Saba shielding introduced recently protecting organs as Bi shielding without degrading image quality. In this study, the Saba shield was modified and primary radiation attenuation values of the shields and entrance skin dose (ESD) on the thyroid were measured with and without shielding. Furthermore, the quality of images obtained using Saba shielding was investigated quantitatively and qualitatively. Saba and Bi shielding reduced the ESD on the thyroid by about 50%. Saba shielding had about 5–7 HU less noise and about 51–65 HU less CT numbers shift in comparison with Bi shielding at a distance of 1 cm from the shields. Saba shielding had no degrading effects on image quality in the patient study.

Published: September 2020

AbstractDespite aggression being detrimental to children’s physical health, mental health and social development, the dispositional and neurological antecedents of aggression in the child are poorly understood. Here we examined the relationship between trait aggression as measured by Buss and Warren’s Aggression Questionnaire and personality traits measured with Big Five Questionnaire for Children in 77 primary-school children and recorded resting-state brain activity (fractional amplitude of low-frequency fluctuations [fALFF]) and resting-state functional connectivity (rsFC) using functional magnetic resonance imaging. The present results showed that trait aggression was negatively correlated with agreeableness and positively correlated with neuroticism. The brain analyses showed that children with a higher propensity for aggression had a lower fALFF mainly in the left superior temporal gyrus, right parahippocampal gyrus and left supramarginal gyrus. Physical and total aggressions were negatively associated with rsFC between the right parahippocampal gyrus and the right putamen. Further analysis revealed that this rsFC could moderate the influence of neuroticism on total aggression. Moreover, the results suggest the presence of a sex difference in the neurodevelopmental mechanisms underlying aggression in middle childhood. Overall, our findings indicate that aggressive children have lower agreeableness and higher neuroticism, and the underlying neural systems are mainly implicated in social judgment and empathy.
A Time-Series Analysis of Contextual-Level Effects on Hate Crime in The Netherlands
Authors: Jacobs Laura , van Spanje Joost 
Published: September 2020

AbstractNowadays, registered hate crimes are on the rise in many Western societies. What explains temporal variation in the incidence of hate crimes? Combining insights from the grievance model and the opportunity model, we study the role of three types of contextual factors: security (terrorism), media (news about terrorism and immigration), and political factors (speech by anti-immigration actors, hate speech prosecution, and high-profile anti-immigration victories). We apply time-series analysis to our original dataset of registered hate crimes in the Netherlands, 2015–2017 (N = 7,219). Findings indicate that terrorist attacks, (both print and online) news on refugees, immigration, and terrorism boost nonviolent hate crime. Similarly, news of the hate speech prosecution of Freedom Party leader Geert Wilders increases nonviolent crime as well. Tentative evidence points to a contagion effect of speech by anti-immigration actors. With regard to violent hate crime, only terrorist attacks had an effect. This effect was modest and only found in one of our models. Hence, the grievance and the opportunities model each partially explain nonviolent hate crime, although the security and media context seem most influential. Our findings help to identify the contextual factors contributing to a climate for hate and suggest that perceived threats play a key role.
Gender Knowledge and Gender Expertise: The Implementation of Gender Mainstreaming in Swedish State Agencies
Authors: Freidenvall Lenita 
Published: September 2020

Abstract
Through an analysis of the Swedish government development program for gender mainstreaming in state agencies—the JIM (Jämställdhet i myndigheter)program—this article analyzes how gender equality is constructed (gender knowledge) and what role specialized knowledge (gender expertise) has in policy implementation. The article claims that even in best-case scenarios, such as Sweden, where intensive efforts to integrate a gender perspective have been undertaken, gender knowledge is based on visions and strategies that do not question prevailing policy paradigms. However, cross-cutting and intersectional conceptualizations of gender equality have created epistemic space for transformative interventions on the part of gender experts.
Original Research: Suicide Among RNs: An Analysis of 2015 Data from the National Violent Death Reporting System
Authors: Patrician Patricia A. , Peterson Cora , McGuinness Teena M. 
Published: September 2020

ABSTRACT

Background:
Suicide is now the 10th leading cause of death in the United States. Suicide rates for health care providers are thought to be higher than for people in other occupations because of job strain and burnout. Despite the National Academy of Medicine's Action Collaborative on Clinician Well-Being and Resilience, which focuses on reducing stress and preventing suicide, a shortage of data limits our understanding of nurse suicide. Neither employers nor professional nursing associations track suicide data.

Purpose:
To determine the number of suicides and estimated rate of suicide among RNs, using data from the National Violent Death Reporting System (NVDRS).

Methods:
We extracted data from the NVDRS, which is based on death certificates, coroner reports, and law enforcement reports, for the year 2015. The National Institute for Occupational Safety and Health's Industry and Occupation Computerized Coding System was used to code the data. Industry and occupation coding experts reviewed the coding for accuracy.

Results:
Analysis of 2015 NVDRS data from 17 states showed that among civilian employed nurses ages 16 to 64 years, the estimated suicide rates for female and male nurses (11.4 and 29.3 per 100,000 nurses, respectively) were each higher than the rates for the comparable total population (8.2 and 26.1 per 100,000 people, respectively).

Conclusions:
Our findings indicate that RNs may die by suicide at higher rates than the total employed population in the 16-to-64-year age range. Implementation of evidence-based approaches to prevent suicide are warranted.
