Published: October 2021

AbstractA new guideline for mitigating indoor airborne transmission of COVID-19 prescribes a limit on the time spent in a shared space with an infected individual (Bazant & Bush,Proceedings of the National Academy of Sciences of the United States of America, vol. 118, issue 17, 2021, e2018995118). Here, we rephrase this safety guideline in terms of occupancy time and mean exhaled carbon dioxide (${\rm CO}_{2}$) concentration in an indoor space, thereby enabling the use of${\rm CO}_{2}$monitors in the risk assessment of airborne transmission of respiratory diseases. While${\rm CO}_{2}$concentration is related to airborne pathogen concentration (Rudnick & Milton,Indoor Air, vol. 13, issue 3, 2003, pp. 237–245), the guideline developed here accounts for the different physical processes affecting their evolution, such as enhanced pathogen production from vocal activity and pathogen removal via face-mask use, filtration, sedimentation and deactivation. Critically, transmission risk depends on the total infectious dose, so necessarily depends on both the pathogen concentration and exposure time. The transmission risk is also modulated by the fractions of susceptible, infected and immune people within a population, which evolve as the pandemic runs its course. A mathematical model is developed that enables a prediction of airborne transmission risk from real-time${\rm CO}_{2}$measurements. Illustrative examples of implementing our guideline are presented using data from${\rm CO}_{2}$monitoring in university classrooms and office spaces.

AbstractIdentification of a new axis of angiotensin-converting enzyme 2 (ACE2)/angiotensin (1–7)/Mas receptor, in the renin-angiotensin system (RAS), has opened a new insight regarding the role of RAS and angiotensin in higher brain functions. ACE2 catabolizes angiotensin II and produces angiotensin (1–7), an agonist of Mas receptor. Mice lacking the Mas receptor (angiotensin 1–7 receptor) exhibit anxiety-like behaviours. The present study was conducted to test the hypothesis of the involvement of ACE2 genetic variant (G8790A) on response to selective serotonin reuptake inhibitors (SSRIs). In a randomised control trial, 200 newly diagnosed Iranian patients with major depressive disorder completed 6 weeks of fluoxetine or sertraline treatment. Patients with a reduction of 50% or more in the Hamilton Rating Scale for Depression score were considered responsive to treatment. G8790A polymorphism was determined in extracted DNAs using restriction fragment length polymerase chain reaction method. Our results show that the A allele and AA and GA genotypes were significantly associated with better response to SSRIs (p = 0.008; OR = 3.4; 95% CI = 1.4–8.5 and p = 0.027; OR = 3.3, 95% CI = 1.2–9.2, respectively). Moreover, patients with GA and AA genotypes responded significantly better to sertraline (p = 0.0002; OR = 9.1; 95% CI = 2.4–33.7). The A allele was significantly associated with better response to sertraline (p = 0.0001; OR = 7.6; 95% CI = 2.5–23.3). In conclusion, our results confirm the role of G8790A in response to some SSRIs.

AbstractWe study in this paper bright late-type giants found in the First Byurakan Survey (FBS) data base. Phase dependent light-curves from large sky area variability data bases such as Catalina Sky Survey (CSS) and All-Sky Automated Survey for Supernovae (ASAS-SN), and the early installment of the third Gaia data release (Gaia EDR3) photometric and astrometric data have been used to characterize our sample of 1 100 M-type giants and 130 C-type stars found at high latitudes. Gaia radial velocities (RV) are available for 134 and luminosities for 158 stars out of 1 100. We show the behaviour of our sample stars in a Gaia color–absolute magnitude diagram (CaMD), the Gaia-2MASS-diagram from Lebzelter et al. with some alternative versions. In this way we explore the potential of these diagrams and their combination for the analysis and interpretation of datasets of LPVs. We show the possibility to classify stars into M- and C-types and to identify the mass of the bulk of the sample stars.

AbstractAdhering to a Mediterranean diet (MD) is associated with reduced CVD risk. This study aimed to explore methods of increasing MD adoption in a non-Mediterranean population at high risk of CVD, including assessing the feasibility of a developed peer support intervention. The Trial to Encourage Adoption and Maintenance of a MEditerranean Diet was a 12-month pilot parallel group RCT involving individuals aged ≥ 40 year, with low MD adherence, who were overweight, and had an estimated CVD risk ≥ 20 % over ten years. It explored three interventions, a peer support group, a dietician-led support group and a minimal support group to encourage dietary behaviour change and monitored variability in Mediterranean Diet Score (MDS) over time and between the intervention groups, alongside measurement of markers of nutritional status and cardiovascular risk. 118 individuals were assessed for eligibility, and 75 (64 %) were eligible. After 12 months, there was a retention rate of 69 % (peer support group 59 %; DSG 88 %; MSG 63 %). For all participants, increases in MDS were observed over 12 months (P< 0·001), both in original MDS data and when imputed data were used. Improvements in BMI, HbA1c levels, systolic and diastolic blood pressure in the population as a whole. This pilot study has demonstrated that a non-Mediterranean adult population at high CVD risk can make dietary behaviour change over a 12-month period towards an MD. The study also highlights the feasibility of a peer support intervention to encourage MD behaviour change amongst this population group and will inform a definitive trial.
An investigation of a Devonian/Carboniferous Boundary section on the Bolivian Altiplano

Published: October 2021

AbstractThe Devonian/Carboniferous Boundary (DCB) interval is associated with mass extinction, isotope excursions and a short glacial episode. This study investigates how boundary extinction and environmental change is expressed in the glacial high-palaeolatitudinal record of the Bolivian Altiplano (western Gondwana). A latest Devonian and early Carboniferous section has been investigated using sedimentology, palynology, total organic carbon and bulk δ13Corganic. The Colpacucho Formation is a Late Devonian shelfal–marine siliciclastic sequence. It is overlain in the study area by a unit of coarse sandstones and sandy diamictites, interpreted as glaciomarine. This distinctive glaciomarine unit is at least 7 km wide and 60–120 m thick with a variably incisive basal contact (<100 m). It is of very latest Famennian age and is a stratigraphic equivalent of proven glacigenic deposits across central South America. The offshore marine Kasa Formation overlies the glacigenic unit above a basal flooding surface. The DCB is 12 m above this flooding surface on the last occurrence of Retispora lepidophyta and significant palynological assemblage changes. This includes the loss of the Umbellasphaeridium saharicum phytoplankton bioprovince, endemic to Gondwana. Marine and terrestrial palynological extinctions are synchronous with a 2 ‰ positive carbon isotope excursion interpreted to be reflective of changes in organic matter delivery and preservation during an interval of environmental stress. These results inform wider debates on global environmental change and mass extinction at the DCB.
Tom F. Wright'sTransatlantic Rhetoricas an American Studies Teaching Resource
Authors: ROBBINS SARAH RUFFING 
Published: October 2021

I first read Tom F. Wright'sTransatlantic Rhetoric: Speeches from the American Revolution to the Suffragettesin late summer 2020, while drafting the syllabus for a new undergraduate rhetoric course in my university's Writing major. I proposed “Writing across Cultural Differences” several years ago and had been waiting eagerly to teach it, only to find myself delivering the inaugural version over Zoom during the coronavirus pandemic. As I write this essay in December 2020, I am in the midst of syllabus-building email exchanges with a now-frequent teaching partner (Victorian literature specialist Linda Hughes), as we prepare to offer a graduate seminar in nineteenth-century transatlantic literature for the fourth time. (Our first foray into collaborative transatlanticism was in 2010.) While we plan for the upcoming class (also – sigh – being taught over Zoom), I am rereading Wright's book, this time focussed more on the “transatlantic” side of his title. A generative resource for my teaching in both these classes,Transatlantic Rhetoricenacts a global brand of American studies, modeling content and methodologies crucial to the field today. To illustrate, I will revisit some ways in which Wright's anthology is informing my pedagogy in this challenging COVID-shaped year.
When Think Tanks Refuse Thinking: Why American Pro-Market Conservatives Oppose Market Integration
Authors: Springer Benedikt 
Published: October 2021

AbstractAmerican pro-market conservatives often oppose use of federal authority to rein in anti-competitive behavior by market actors. Competitive barriers, whether created by local jurisdictions or the absence of national competitive rules, go unaddressed. In international comparison, especially considering the European Union's use of central authority for market openness, this is quite puzzling. Based on interviews and archival research, I trace inattention to market barriers to contradictions within Hayek's neoliberalism and an enthusiastic reception within the American academy of one possible interpretation of those writings. This conception of markets—competitive federalism—diffused into the conservative law and economics movements, think tanks, and eventually mainstream conservative politics. It permitted conservatism to align a strong pro-market rhetoric with demands for states’ rights and federal retrenchment, albeit side-stepping many significant issues in economic theory and policy. Thus, conservatives pursue spending and tax cuts, deregulation and decentralization, often to the detriment of market openness.
Association of family characteristics with health status and needs among children with congenital heart disease
Authors: Peterson Ashley , Cochran Elizabeth , Tumin Dmitry , Sarno Lauren A. 
Published: October 2021

AbstractIntroduction:Low socio-economic status is associated with poorer quality of life among children with congenital heart disease (CHD), but this finding is based on disparities among children remaining under cardiology follow-up. We used a population-based health survey data set to analyse the impact of socio-economic status on health and functional status among children with CHD.Materials and methods:We used 2007–2018 National Health Interview Survey data, selecting children 2–17 years of age who had been diagnosed with CHD. Outcomes included caregiver-rated general health, presence of functional limitations, number of missed school days, need for special education, and need for special equipment related to the child’s health conditions. Socio-economic status measures included maternal educational attainment, food stamp programme participation, poverty status, and insurance coverage.Results:Based on a sample of 233 children with CHD, 10% had fair or poor health, 38% reported having any health-related limitation on their usual activities, 11% needed special equipment, and 27% received special education services. On multivariable analysis, lower maternal educational attainment was correlated with worse caregiver-rated health, and children without insurance were especially likely to experience functional limitations. Black children with CHD had significantly worse caregiver-rated health compared to White children (ordered logit odds ratio: 0.19; 95% confidence interval: 0.08, 0.45; p < 0.001).Conclusions:In a population-based survey of children with CHD, race and several measures of socio-economic status disadvantage were associated with worse health outcomes. Further evaluation of social determinants of health during cardiology follow-up may help improve outcomes for children with CHD in socio-economically disadvantaged families.

Published: October 2021

AbstractIntroduction:Cardiopulmonary exercise test (CPET) allows quantification of functional capacity of patients with Fontan. The objective of this study was to determine the role of CPET parameters in predicting a higher maximum oxygen consumption (VO2 max) and to analyse the role of CPET parameters in predicting an unfavourable outcome.Methods:A retrospective, cross-sectional, descriptive study was carried out on 57 patients with Fontan, who had undergone incremental CPET with cycloergometer between 2010 and 2020. Determinants of VO2 max and determinants of clinical deterioration were analysed.Results:In the univariate analysis, the variables significantly related to VO2 max were: age, sex, body mass index (BMI), years of Fontan evolution, intracardiac Fontan, oxygen consumption at anaerobic threshold (VO2AT), CO2 equivalents at anaerobic threshold (VE/VCO2) and chronotropic insufficiency. The multiple linear regression model that best fitted the relationship between VO2 max and independent variables (correlation coefficient 0.73) included sex (correlation index 3.35; p = 0.02), BMI (−0.27; p = 0.02), chronotropic failure (−2.79; p = 0.01) and VO2AT (0.92; p < 0.0001). In the univariate analysis of the prognostic CPET variables related to an unfavourable clinical situation, significance was only obtained with chronotropic insufficiency (p = 0.003). In multivariate analysis, chronotropic insufficiency maintains its association [p= 0.017, OR = 4.65 (1.3–16.5)].Conclusions:In conclusion, together with the anthropometric parameters universally related to VO2 max, chronotropic insufficiency and VO2AT are the main determinants of functional capacity in patients with Fontan. Moreover, chronotropic insufficiency is closely related to unfavourable clinical evolution. Our data would support the intensive treatment of chronotropic insufficiency in order to improve the quality of life and the clinical situation of patients with Fontan.
Dextrose 50% versus Dextrose 10% or Dextrose Titration for the Treatment of Out-of-Hospital Hypoglycemia: A Systematic Review

Published: October 2021

AbstractIntroduction:Paramedics commonly administer intravenous (IV) dextrose to severely hypoglycemic patients. Typically, the treatment provided is a 25g ampule of 50% dextrose (D50). This dose of D50 is meant to ensure a return to consciousness. However, this dose may cause harm and lead to difficulties regulating blood glucose levels (BGLs) post-treatment. It is hypothesized that a lower concentration, such as 10% dextrose (D10), may improve symptoms while minimizing harm.Methods:PubMed, Embase, CINAHL, and Cochrane Central were systematically searched on September 15, 2020. The PRISMA guidelines were followed. GRADE and risk of bias were applied to determine the certainty of the evidence. Primary literature investigating the use of IV dextrose in hypoglycemic diabetic patients presenting to paramedics or the emergency department was included. Outcomes of interest included safety, efficacy (symptom resolution), and BGL.Results:Of 680 abstracts screened, 51 full-text articles were reviewed, with eleven studies included. Data from three randomized controlled trials (RCTs) and eight observational studies were analyzed. A single RCT comparing D10 to D50 was identified. The primary significant finding of the study was an increased post-treatment glycemic profile by 3.2mmol/L in the D50 group; no other outcomes had significant differences between groups. When comparing pooled data from all the included studies, there was greater symptom resolution in the D10 group (95.9%) compared to the D50 group (88.8%). However, the mean time to resolution was approximately four minutes longer in the D10 group (4.1 minutes [D50] versus 8.0 minutes [D10]). There was a greater need for subsequent doses with the use of D10 (19.5%) compared to D50 (8.1%). The post-treatment glycemic profile was lower in the D10 group at 6.2mmol/L versus 8.5mmol/L in the D50 group. Both treatments had nearly complete resolution of hypoglycemia: 98.7% (D50) and 99.2% (D10). No adverse events were observed in the D10 group (0/1057) compared to 13/310 adverse events in the D50 group.Conclusion:Studies show D10 may be as effective as D50 at resolving symptoms and correcting hypoglycemia. Although the desired effect can take several minutes longer, there appear to be fewer adverse events. The post-D10-treatment BGL may result in fewer untoward hyperglycemic episodes.
Assessing Racial/Ethnic and Gender Gaps in Political Science PhD Students’ Methodological Self-Efficacy
Authors: Smith Amy Erica , Gillooly Shauna N. , Hardt Heidi 
Published: October 2021

ABSTRACTMost research on diversity within political methodology focuses on gender while overlooking racial and ethnic gaps. Our study investigates how race/ethnicity and gender relate to political science PhD students’ methodological self-efficacy, as well as their general academic self-efficacy. By analyzing a survey of 300 students from the top 50 US-based political science PhD programs, we find that race and ethnicity correlate with quantitative self-efficacy: students identifying as Black/African American and as Middle Eastern/North African express lower confidence in their abilities than white students. These gaps persist after accounting for heterogeneity among PhD programs, professional and socioeconomic status, and preferred methodological approach. However, small bivariate gender gaps disappear in multivariate analysis. Furthermore, gaps in quantitative self-efficacy may explain racial/ethnic disparities in students’ broader academic self-efficacy. We argue that the documented patterns likely lead to continued underrepresentation of marginalized groups in the political methodology student body and professoriate.
Efficient bilingual lexicon extraction from comparable corpora based on formal concepts analysis
Authors: Chebel Mohamed , Latiri Chiraz , Gaussier Eric 
Published: October 2021

AbstractBilingual corpora are an essential resource used to cross the language barrier in multilingual natural language processing tasks. Among bilingual corpora, comparable corpora have been the subject of many studies as they are both frequent and easily available. In this paper, we propose to make use of formal concept analysis to first construct concept vectors which can be used to enhance comparable corpora through clustering techniques. We then show how one can extract bilingual lexicons of improved quality from these enhanced corpora. We finally show that the bilingual lexicons obtained can complement existing bilingual dictionaries and improve cross-language information retrieval systems.

Abstract

Objective:
Approximately 50 % of Dutch community-dwelling older adults does not meet protein recommendations. This study assesses the effect of replacing low protein foods with protein-rich alternatives on the protein intake of Dutch community-dwelling older adults.

Design:
The Dutch National Food Consumption Survey—Older Adults 2010–2012 (DNFCS-OA) was used for scenario modelling. Dietary intake was estimated based on two 24-h recalls. Commonly consumed products were replaced by comparable products rich in protein (scenario 1), foods enriched in protein (scenario 2) and a combination of both (scenario 3). Replacement scenarios were confined to participants whose dietary protein intake was < 1·0 g/kg BW/d (n 391). Habitual protein intake of all older adults was estimated, adjusting for effects of within-person variation in the 2-d intake data.

Setting:
A simulation study based on the DNFCS-OA.

Participants:
727 Dutch community-dwelling older adults aged 70+.

Results:
Mean protein intake of the total population increased from 1·0 to 1·2 g/kg BW/d (scenarios 1 and 2) and to 1·3 g/kg BW/d (scenario 3). The percentage of participants with intakes of ≥ 1·0 g/kg BW/d increased from 47·1 % to 91·4 %, 90·2 % and 94·6 %, respectively, in scenarios 1, 2 and 3. The largest increases in protein intake were due to replacements in food groups: yoghurt, cream desserts and pudding, potatoes, vegetables and legumes and non-alcoholic beverages and milk in scenario 1 and bread; yoghurt, cream desserts and pudding and soups in scenario 2.

Conclusions:
This simulation model shows that replacing low protein foods with comparable alternatives rich in protein can increase the protein intake of Dutch community-dwelling older adults considerably. Results can be used as a basis for nutritional counselling.
Utilizing cover crops for weed suppression within buffer areas of 2,4-D-resistant soybean

Published: October 2021

AbstractCover crops can be utilized to suppress weeds via direct competition for sunlight, water, and soil nutrients. Research was conducted to determine if cover crops can be used in label-mandated buffer areas in 2,4-D-resistant soybean cropping systems. Delaying termination of cover crops containing cereal rye to at or after soybean planting resulted in a 25 to more than 200 percentage point increase in cover crop biomass compared to a control treatment. Cover crops generally improved horseweed control when 2,4-D was not used. Cover crops reduced grass densities up to 54% at four of six site-years when termination was delayed to after soybean planting. Cover crops did not reduce giant ragweed densities. Cover crops reduced waterhemp densities by up to 45%. Cover crops terminated at or after planting were beneficial within buffer areas for control of grasses and waterhemp, but not giant ragweed. Yield reductions of 14% to 41% occurred when cover crop termination was delayed to after soybean planting at three of six site-years. Terminating the cover crops at planting time provided suppression of grasses and waterhemp within buffer areas and had similar yield to the highest-yielding treatment in five out of six site-years.
