Alcohol Use among Swedish Patients with Stress-Induced Exhaustion Disorder, and Its Relation to Anxiety, Depression, and Health-Related Quality of Life
Authors: Grossi G. , Jeding K. , Söderström M. , Perski A. , Alföldi P. , Osika W. 
Published: March 2021

AbstractHarmful drinking may be a cause and an effect of psychological distress, and compromises the effects of treatment for psychiatric conditions. There is a paucity of studies investigating patterns of alcohol consumption among patients with stress-induced exhaustion disorder (SED). The aims of this investigation were (1) to assess the prevalence of self-rated hazardous drinking in a sample of 808 Swedish patients with SED (mean age 43 ± 9 years, 84% women), and (2) to investigate differences in sociodemographic variables, psychological symptoms, health-related quality of life, and sleep variables between patients with different drinking patterns The design was cross-sectional and data were collected with questionnaires at pre-treatment. Twelve percent of female and 13% of male patients reported Alcohol Use Disorder Identification Test (AUDIT) scores indicating hazardous drinking. Female patients with hazardous drinking reported higher levels of anxiety and depression and lower mental wellbeing, than other women. Female patients reporting no drinking reported poorer physical function and more pain, than other women. No differences were seen between male patients with different drinking patterns. Although patients with SED report a lower frequency of harmful drinking than other psychiatric samples, alcohol consumption needs to be addressed in the assessment and treatment of this condition.
Acute severe ulcerative colitis: management advice for internal medicine and emergency physicians
Authors: Rosiou Konstantina , Selinger Christian Philipp 
Published: March 2021

AbstractAcute severe ulcerative colitis is a medical emergency that warrants in-patient management. This is best served within a multidisciplinary team setting in specialised centres or with expert consultation. Intravenous corticosteroids remain the cornerstone in the management of ASUC and should be initiated promptly, along with general management measures and close monitoring of patients. Unfortunately, one-third of patients will fail to respond to steroids. Response to intravenous corticosteroid therapy needs to be assessed on the third day and rescue therapies, including cyclosporine and infliximab, should be offered to patients not responding. Choice of rescue therapy depends on experience, drug availability and factors associated with each individual patient, such as comorbidities, previous medications or contra-indications to therapy. Patients who have not responded within 7 days to rescue therapy must be considered for surgery. Surgery is a treatment option in ASUC and should not be delayed in cases of failure of medical therapy, because such delays increase surgical morbidity and mortality. This review summarises the current management of acute severe ulcerative colitis and discusses potential future developments.
Conceptualizing Motives for Migration: a Typology of Italian Migrants in the Athens Area
Authors: Delli Paoli Angela , Maddaloni Domenico 
Published: March 2021

AbstractMigration flows from a southern European country to another one have received scarce attention so far. This is especially true for Italians migrating to Greece or, more specifically, the Athens area. Thus, there are limited insights as to the reasons why Italians are leaving and why they have been choosing Greece as their destination. This paper looks at their motives for migrating and their destination choice in order to understand the diversity of migratory trajectories through a typology. In order to do this, we carried out in-depth interviews to Italians living, both permanently and temporarily, in the Athens area, employing snowball sampling. As a result, we have identified 5 types of Italian immigrants in Athens:Mediterranean,nomadic,work, entrepreneurial, andmarriage migrants.Mediterraneanmigrants are driven by the typically Mediterranean character of climate, landscape, food, and culture in their deliberate choice of Athens.Nomadicmigrants have casually chosen Athens to satisfy their need of continuous physical mobility and multiple moorings as a defining aspect of their identity.Workmigrants are motivated by the search of a job regardless of the place and work content.Entrepreneurialmigrants are motivated by a vocation for a professional career in Athens. Finally, formarriagemigrants, the choice of Athens is a consequence of a couple choice and shared life projects.
Reductive Conversion of Biomass-Derived Furancarboxylic Acids with Retention of Carboxylic Acid Moiety
Authors: Nakagawa Yoshinao , Yabushita Mizuho , Tomishige Keiichi 
Published: March 2021

AbstractCatalytic reduction systems of 2-furancarboxylic acid (FCA) and 2,5-furandicarboxylic acid (FDCA) with H2 without reduction of the carboxyl groups are reviewed. FCA and FDCA are produced from furfural and 5-hydroxymethylfurfural which are important platform chemicals in biomass conversions. Furan ring hydrogenation to tetrahydrofuran-2-carboxylic acid (THFCA) and tetrahydrofuran-2,5-dicarboxylic acid (THFDCA) easily proceeds over Pd catalysts. Hydrogenolysis of one C–O bond in the furan ring produces 5-hydroxyvaleric acid (5-HVA) and 2-hydroxyadipic acid. 2-Hydroxyvaleric acid is not produced in the reported systems. 5-HVA can be produced as the lactone form (δ-valerolactone; DVL) or as the esters depending on the solvent. These reactions proceed over Pt catalysts with good yields (~ 70%) at optimized conditions. Hydrogenolysis of two C–O bonds in the furan ring produces valeric acid and adipic acid, the latter of which is a very important chemical in industry and its production from biomass is of high importance. Adipic acid from FDCA can be produced directly over Pt-MoOx catalyst, indirectly via hydrogenation and hydrodeoxygenation as one-pot reaction using the combination of Pt and acid catalysts such as Pt/niobium oxide, or indirectly via two-step reaction composed of hydrogenation catalyzed by Pd and hydrodeoxygenation catalyzed by iodide ion in acidic conditions. Only the two-step method can give good yield of adipic acid at present.

Thus all subgroups of a groupGare transitively normal if and only if normality is a transitive relation in every subgroup ofG(i.e.Gis a$$\overline{T}$$T¯-group). It is proved that a groupGwith no infinite simple sections satisfies the minimal condition on subgroups that are not transitively normal if and only if either Gis Černikov or a$${\overline{T}}$$T¯-group.
Commercialization of Aframomum spp. in Africa: a Systematic Review of Literature and Supporting Botanical Vouchers
Authors: Knippers Ronja Hermiene Maria , Gallois Sandrine , van Andel Tinde 
Published: March 2021

AbstractAframomum (Zingiberaceae) is a genus of plants native to tropical Africa that are sold on African markets as spices and traditional medicine. Not all species of Aframomum are equally abundant or widespread, and no overview exists of the specific species traded or the quality of the species identifications in publications referencing the sale of Aframomum. Through a systematic literature review, we show that 14 species of Aframomum are sold in 15 African countries. The majority of the studies were done in Nigeria and Cameroon and A. melegueta was the most frequently reported species in trade. A. kayserianum was the only commercialized species with confirmed conservation issues. Our literature review shows extensive knowledge gaps regarding the commercialization of Aframomum in Africa. Most studies did not include herbarium vouchers, or only used market-sourced plant material, which impedes the possibilities for species verifications. Additionally, most East African countries were devoid of relevant research. These gaps can be bridged by future research in East Africa and voucher collection from living material. Information on the conservation status of traded Aframomum species can be obtained by population studies on wild resources and documenting local domestication efforts, as the cultivation of marketed species tends to relieve the pressure from wild resources.

Published: March 2021

AbstractAcute infections are associated with an elevated cardiovascular risk. However, little is known about the interactions of acute inflammatory responses and the cardiovascular system. We therefore aimed to evaluate effects of acute inflammatory stimuli mediated by LPS administration on a set of 89 cardiovascular biomarkers. A single-blinded, placebo-controlled cross-over study using the human endotoxin model was performed. Ten healthy men were administered lipopolysaccharide (LPS) or placebo on two different study days after an overnight fast. Eighty-nine different cardiovascular biomarkers were measured repetitively over 48 h. Out of 89 cardiovascular biomarkers, 54 markers were significantly influenced by LPS infusion. The observed biomarker response to inflammation was more pronounced and complex than anticipated. In conclusion, our data show that the cardiovascular system is under enormous distress in response to experimental low-dose inflammation in humans, as demonstrated by a significant effect on 54 of the 89 biomarkers tested.
Analysis of urban heat island characteristics and mitigation strategies for eight arid and semi-arid gulf region cities
Authors: Abulibdeh Ammar 
Published: March 2021

AbstractThe aim of the study is, therefore, to analyze the formation of the UHIs in eight different cities in arid and semi-arid regions. The analysis is based on land cover (LC) classification (urban, green, and bare areas). The study found that bare areas had the highest mean LST values compared to the urban and green areas. The results show that the difference in temperatures between the bare areas and the urban areas ranges between 1 and 2 °C, between the bare areas and green areas ranges between 1 and 7 °C, and between the urban areas and green areas ranges between 1 and 5 °C. Furthermore, the LST values varied for each of the LULC categories, and hence some areas in the three categories had lower or higher LST values than in other categories. Hence, one category may not always have the highest LST value compared to other categories. The outcomes of this study may, therefore, have critical implications for urban planners who seek to mitigate UHI effects in arid and semi-arid urban areas.
Stakeholder Engagement in Adoption, Implementation, and Sustainment of an Evidence-Based Intervention to Increase Mammography Adherence Among Low-Income Women
Authors: Holcomb Jennifer , Ferguson Gayla M. , Sun Jiali , Walton Gretchen H. , Highfield Linda 
Published: March 2021

AbstractMulti-level organizational stakeholder engagement plays an important role across the research process in a clinical setting. Stakeholders provide organizational specific adaptions in evidence-based interventions to ensure effective adoption, implementation, and sustainability. Stakeholder engagement strategies involve building mutual trust, providing clear communication, and seeking feedback. Using constructs from the Consolidated Framework for Implementation Research and The International Association for Public Participation spectrum, a conceptual framework was created to guide stakeholder engagement in an evidence-based intervention to increase mammography appointment adherence in underserved and low-income women. A document review was used to explore the alignment of the conceptual framework with intervention activities and stakeholder engagement strategies. The results indicate an alignment with the conceptual framework constructs and a real-world application of stakeholder engagement in a mammography evidence-based intervention. The conceptual framework and stakeholder engagement strategies can be applied across a range of community-based cancer programs and interventions, organizations, and clinical settings.

Published: March 2021

AbstractTaste dysfunction (TD) has been recognised, together with olfactory dysfunction, as a key presenting symptom of COVID-19. The capability to recognise flavours, flavour intensities and aroma characteristics can be highly variable within the same population, as well as potentially diverse between culturally different populations. The aims of this study are to evaluate whether a difference in the types of TD presentation amongst COVID-19 positive subjects can be demonstrated and whether a difference exists between populations of different cultures.

Highlights

A zero-reflection-induced phase singularity is achieved through precisely controlling the resonance characteristics using two-dimensional nanomaterials.

An atomically thin nano-layer having a high absorption coefficient is exploited to enhance the zero-reflection dip, which has led to the subsequent phase singularity and thus a giant lateral position shift.

We have improved the detection limit of low molecular weight molecules by more than three orders of magnitude compared to current state-of-art nanomaterial-enhanced plasmonic sensors.

Abstract
Detection of small cancer biomarkers with low molecular weight and a low concentration range has always been challenging yet urgent in many clinical applications such as diagnosing early-stage cancer, monitoring treatment and detecting relapse. Here, a highly enhanced plasmonic biosensor that can overcome this challenge is developed using atomically thin two-dimensional phase change nanomaterial. By precisely engineering the configuration with atomically thin materials, the phase singularity has been successfully achieved with a significantly enhanced lateral position shift effect. Based on our knowledge, it is the first experimental demonstration of a lateral position signal change > 340 μm at a sensing interface from all optical techniques. With this enhanced plasmonic effect, the detection limit has been experimentally demonstrated to be 10–15 mol L−1 for TNF-α cancer marker, which has been found in various human diseases including inflammatory diseases and different kinds of cancer. The as-reported novel integration of atomically thin Ge2Sb2Te5 with plasmonic substrate, which results in a phase singularity and thus a giant lateral position shift, enables the detection of cancer markers with low molecular weight at femtomolar level. These results will definitely hold promising potential in biomedical application and clinical diagnostics.

Polynomization of the Chern–Fu–Tang conjecture
Authors: Heim Bernhard , Neuhauser Markus 
Published: March 2021

AbstractBessenrodt and Ono’s work on additive and multiplicative properties of the partition function and DeSalvo and Pak’s paper on the log-concavity of the partition function have generated many beautiful theorems and conjectures. In January 2020, the first author gave a lecture at the MPIM in Bonn on a conjecture of Chern–Fu–Tang, and presented an extension (joint work with Neuhauser) involving polynomials. Partial results have been announced. Bringmann, Kane, Rolen, and Tripp provided complete proof of the Chern–Fu–Tang conjecture, following advice from Ono to utilize a recently provided exact formula for the fractional partition functions. They also proved a large proportion of Heim–Neuhauser’s conjecture, which is the polynomization of Chern–Fu–Tang’s conjecture. We prove several cases, not covered by Bringmann et. al. Finally, we lay out a general approach for proving the conjecture.
Form and Substance in Singapore Constitutional and Administrative Law
Authors: CHNG Kenny 
Published: March 2021

AbstractWhile Atiyah's and Summers’ concepts of form and substance in the context of constitutional law are often associated with constitutional interpretation, they can also be fruitfully applied to other areas of constitutional and administrative law. The intent of this paper is to apply the concepts of form and substance to Singapore constitutional and administrative law to illustrate that beyond constitutional interpretation, formalism is an apt description for several key areas of constitutional and administrative law doctrine and reasoning in Singapore, even to the extent of being formalistic. This article will argue that formalism in legal reasoning obtains in several important constitutional and administrative law doctrines in Singapore – specifically in the grounds of judicial review, ouster clause doctrine, and the rules on standing. This article will also evaluate the implications of these findings for the development of constitutional and administrative law in Singapore.
“The Mother of Combines”: Representations of the United States in Early Canadian Discourse on the Combines Problem and the Formation of Canadian National Identity
Authors: Hoffman C. P. 
Published: March 2021

AbstractIn 1887, Canada was in a fervour over so-called “combines,” a term used to cover price-fixing schemes, pool agreements, trusts, and other cartel arrangements. The public debate led to the passage in 1889 of the Anti-Combines Act, the world’s first modern competition statute, enacted a year prior to the United States’ Sherman Antitrust Act. But while Canada acted before its neighbour to the south, the United States was omnipresent in the Canadian debates in four ways: as a benchmark against which the Canadian economy and the combines problem should be judged; as a model for potential legal action; as a potential economic liberator; and as the very source and propagator of the combines problem. Canadians thus alternately presented the United States as saviour or devil, as paragon or antithesis. The result was a paradox of a sort: Canadians borrowed American ideas in order to avoid becoming American.
Merging One's Way to the Top: AB Inbev versus Heineken
Authors: Doan Minh Phuong , Sercu Piet 
Published: March 2021

AbstractLeuven's Den Hoorn brewery, now AB Inbev SA, has become the world's largest brewing group by far, but critics say the company overpaid for its acquisitions. In this article, we study typical stock market reactions to the many takeover announcements by AB Inbev and the industry's runner-up, Heineken. Unlike Heineken's, the market leader's takeover announcements were met by, on average, a –2% price reaction in the stock market in the announcement month, but most of that is already undone in the next month. For Heineken, the same pattern shows up, only faster: the V-shaped reaction takes a few weeks rather than a few months. Such V-reactions may actually reflect a temporary rise in uncertainty rather than overpaying. The finding that reactions are reversed and heterogeneous across firms, raises issues of interpretation and optimal test design of event studies. (JEL Classifications: G12, G14, G17)

AbstractThe gluten-free (GF) diet is the only treatment for coeliac disease (CD). While the GF diet can be nutritious, increased reliance on processed and packaged GF foods can result in higher fat/sugar and lower micronutrient intake in children with CD. Currently, there are no evidence-based nutrition guidelines that address the GF diet. The objective of this cross-sectional study was to describe the methodological considerations in forming a GF food guide for Canadian children and youth (4–18 years) with CD. Food guide development occurred in three phases: (1) evaluation of nutrient intake and dietary patterns of children on the GF diet, (2) pre-guide stakeholder consultations with 151 health care professionals and 383 community end users and (3) development of 1260 GF diet simulations that addressed cultural preferences and food traditions, diet patterns and diet quality. Stakeholder feedback identified nutrient intake and food literacy as important topics for guide content. Except for vitamin D, the diet simulations met 100 % macronutrient and micronutrient requirements for age–sex. The paediatric GF plate model recommends intake of >50 % fruits and vegetables (FV), <25 % grains and 25 % protein foods with a stronger emphasis on plant-based sources. Vitamin D-fortified fluid milk/unsweetened plant-based alternatives and other rich sources are important to optimise vitamin D intake. The GF food guide can help children consume a nutritiously adequate GF diet and inform policy makers regarding the need for nutrition guidelines in paediatric CD.
