Abstract

Background
Illness perceptions in psoriasis have an impact on adherence and disability. Changes in dermatological healthcare provision during the Covid-19 pandemic and distress may have affected illness perceptions in psoriasis patients.

Objectives
To test whether illness perceptions about psoriasis changed during the first year of the Covid-19 pandemic compared to pre-pandemic in a tertiary population with psoriasis and whether pandemic effects differed depending on depressive burden, given this population's high depression prevalence.

Methods
In a cross-sectional survey of n = 188 tertiary patients with dermatologist-confirmed psoriasis recruited before and during the pandemic, eight illness perceptions domains were assessed using the Brief-Illness Perceptions Questionnaire (BIPQ). Presence of depression was assessed with the Hospital Anxiety and Depression Scale (HADS).

Results
Beliefs about treatment control and patients' understanding of psoriasis were significantly worse in patients responding during the pandemic compared to before Covid-19. These differences were greater when depression was absent (treatment control: adjusted p &lt; 0.001; coherence: adjusted p = 0.01). However, participants during the pandemic felt less emotionally affected (adjusted p = 0.02) and concerned (adjusted p = 0.007) about psoriasis, independently of depression.

Conclusions
We found diverse pandemic effects on illness perception domains in psoriasis. Uncertainty and reduced healthcare access may drive poorer treatment and coherence beliefs during Covid-19. These beliefs can hinder patients' health-promoting behaviours and may explain the high pandemic non-adherence reported previously in psoriasis. Appropriate interventions are needed to establish positive long-term cognitions and improve psoriasis management, for example, using the PsoWell patient materials. Dermatology services should invest in engaging and educating patients regardless of concurrent psychological distress.

AbstractPorphyrinic covalent organic frameworks (COFs, specifically DhaTph) in the absence or presence of Cu2+in porphyrin centers, were synthesized by a Schiff base condensation reaction of 5,10,15,20‐tetrakis(4‐aminophenyl)‐porphyrin (Tph) and 2,5‐dihydroxyterephthalaldehyde (Dha). Using 2,4,6‐trimethylbenzaldehyde (TBA) as a competition reagent, the hollow DhaTph Tubes and DhaTph‐Cu Tubes were obtained under solvothermal conditions. A detailed mechanism of formation of the tubular microstructure revealed the time‐dependent transformation into the tube via migration of the unstable central part of the initial solid rod. The DhaTph‐Cu Tubes possessed a high photoreduction efficiency of CO2and the rate constants of CO and methane production are 15.9 and 13.7 μmol g−1 h−1in the absence of any cocatalysts, which is about 3 and 7.6 times of DhaTph COF, respectively. The high effective photocatalytic reduction of CO2activity of DhaTph‐Cu Tubes is attributed to the high specific surface area, strong absorption of visible light, and the fast separation and transferability of electrons and holes. This work not only provides in‐depth insights into the formation mechanism of the tubular COF but also reveals the relation between the morphology and the photocatalytic property based on COFs.

Published: July 2022

AbstractMillions of tons of waste glass are produced globally. The use of waste glass in concrete is an environmentally friendly solution, contributing to sustainable construction practices. This study investigates the potential of using recycled waste glass powder (RWGP) in foamed concrete nonload bearing wall panels as acoustic barriers. This study investigates the axial and flexural behavior of wall panels constructed with foamed concrete incorporating RWGP. A total of ten 900 mm long and 700 mm wide wall panels of foamed concrete with RWGP reinforced with 7.6 mm diameter steel mesh were cast and tested. Five wall panels were 75 mm thick and reinforced with one layer of steel mesh and the other five wall panels were 120 mm thick and reinforced with two layers of steel mesh. The experimental results exhibited that 120 mm thick wall panels sustained significantly higher peak axial and flexural loads, bending moments, axial deformations at peak axial load and midspan deflections at peak flexural load than 75 mm thick wall panels. The available design codes of masonry structures underestimated the peak axial loads and the bending moments of wall panels by about 9% and 17%, respectively.
Silencing lncRNA Snhg6 mitigates bleomycin‐induced pulmonary fibrosis in mice via miR‐26a‐5p/TGF‐β1‐smads axis

AbstractIdiopathic pulmonary fibrosis (IPF) is an interstitial pulmonary disease with slow onset and high mortality. Epithelial–mesenchymal transition (EMT) is a significant condition for tissue fibrosis, and lncRNA‐Snhg6 (small nucleolar RNA host gene 6) is related to EMT in some cancer cells, but its role in pulmonary fibrosis remains obscure. Here, we found that TGF‐β1 and Snhg6 were up‐regulated in lung tissues of BLM‐induced lung fibrosis mouse, and Snhg6 expression was significantly increased in primary lung fibroblasts after BLM treatment. Snhg6 knockdown notably alleviated the pulmonary dysfunction, and the increase of fibrosis area and collagen deposition induced by BLM. MiR‐26a‐5p was downregulated in BLM‐induced fibrotic lung tissues, and it was negatively regulated by Snhg6. Silencing Snhg6 markedly alleviated the TGF‐β1‐induced increase in fibrotic marker expression, cell proliferation, migration and differentiation, as well as the nuclear transport of p‐Smad2/3 by modulating miR‐26a‐5p expression in mouse lung fibroblasts. Moreover, overexpressing Snhg6‐induced collagen accumulation and fibroblast activation in fibroblasts, which was reversed by treatment with miR‐26a‐5p mimic or oxymatrine (an inhibitor of TGF‐β1‐Smads pathway). Interestingly, silencing Snhg6 in vivo mitigated BLM‐driven pulmonary fibrosis by regulating the miR‐26a‐5p/TGF‐β1‐Smads axis. Our data revealed that Snhg6 contributed to the process of BLM‐driven lung fibrosis in mouse by modulating the miR‐26a‐5p/TGF‐β1‐Smads axis, suggesting that Snhg6 might be a therapeutic target for lung fibrosis.

AbstractBackground and ObjectiveTo determine the population prevalence and associated health impairment of disorders of gut‐brain interaction (DGBI) across Great Britain, and the emphasis placed upon them within medical education.MethodsAn Internet‐based cross‐sectional health survey was completed by 1906 general population adults across Great Britain without self‐reported organic GI disease. The survey enquired for demographics, symptom‐based criteria for Rome IV DGBI, healthcare use, non‐GI somatic symptoms, and quality of life. As a separate analysis, we evaluated which DGBI are considered core knowledge at undergraduate medical school level and post‐graduate specialization level for Gastroenterologists and General Practitioners.ResultsThe overall prevalence of DGBI across Great Britain was 37%, being similar for England (37%), Scotland (33%), and Wales (36%); p = 0.66. There was no difference between English regions (range 33%–43%, p = 0.26). The prevalence of DGBI was highest in those aged 18–40 years (40%), then 40–64 years (37%), and least amongst those ≥65 years (29%); p < 0.001. The most common DGBI were bowel disorders (30%), followed by gastroduodenal (10.5%), anorectal (8.1%) and oesophageal disorders (6.2%). Individuals with DGBI were significantly more likely than those without DGBI to have increased GI‐related healthcare visits, medication use, surgical interventions, non‐GI somatic symptoms, and reduced quality of life. One‐in‐three people with DGBI had multiple GI organ regions involved and this correlated with increased health impairment (p < 0.001).The only DGBI mentioned across all medical training curricula is irritable bowel syndrome, while the General Practitioner and Gastroenterology Curricula also recognise the outdated term non‐ulcer dyspepsia (as opposed to functional dyspepsia). The 2010 Gastroenterology Curriculum also includes functional constipation and disordered defecation, with the incoming 2022 iteration adding in functional upper GI syndromes, functional abdominal pain, and opioid‐induced GI disturbances.ConclusionDisorders of gut‐brain interaction are common across Great Britain and incur substantial health impairment. However, they are generally under‐taught within the British medical education system. Increasing awareness and education of disorders of gut‐brain interaction might improve patient outcomes.
Effect of timber removal on the total nutrient fluxes from a freshwater‐supplying forested watershed

Published: July 2022

AbstractEffects of 18% thinning on nutrient fluxes were investigated in a broadleaf forest. Streamflow and suspended sediment were sampled during the calibration and treatment periods for the treatment and control watersheds to determine total nutrient fluxes through bedload sediment and runoff. Streamflow was measured, and water samples were collected from the streams of the watersheds. The volume of the bedload deposited in both weirs' pools was measured, and sediment deposits were sampled at the ends of the calibration and treatment periods. Water and sediment samples were analyzed for calcium (Ca2+), magnesium (Mg2+), Kjeldahl nitrogen (KN), sodium (Na+), potassium (K+), iron (Fe3+), and sulfur (S2−). Results showed that there was only a significant increase in KN loss from 0.01 kg/ha to 0.10 kg/ha and from 0.04 kg/ha to 2.41 kg/ha in the second and the third post‐treatment years, respectively (P < 0.05). Thinning was not intensive to change nutrient outflow in the study site.Practitioner Points

The 18% thinning was not intensive enough to increase the total nutrient flux, deteriorate water chemical quality, and hence threaten aquatic life in the stream water.
Significant increases were found only in KN outflow after timber removal.
If there is no information about the effect of timber harvest on nutrient loss in a specific watershed, the application of evenly distributed low‐intensity timber harvest may be a good option to protect stream water quality in forested watersheds.
Further investigations are needed about the effects of various timber harvest intensities on physical water quality (odor, color, turbidity, taste, temperature, etc.) and biological characteristics (population and biodiversity of aquatic organisms) of the stream water for making better water management plans.

AbstractWhile West Africa has become the focus of media and policy discussions on migration because of its high level of both labour migration and forced displacement, there is a general paucity of data on the dynamics of migration flows and their impacts on socio-economic development in the sub-region. As a way of helping to fill some of the existing knowledge gaps which make it difficult to integrate migration into development planning processes, this book has employed various theoretical perspectives to analyse the trends, patterns, drivers, and socio-economic impacts of both voluntary and involuntary migration in West Africa. The authors have also examined policy responses to intractable migration-related challenges, and outlined policy recommendations for improving migration governance, strengthening mechanisms for the protecting, and maximining the developmental impacts of migration for both countries of origin and destination of migrants.
Free Movement and Regional Integration in the ECOWAS Sub-Region
Authors: Garba Faisal , Yeboah Thomas 
Published: July 2022

AbstractThis chapter situates attempts at promoting free movement of persons and regional integration in West Africa in a historical perspective. Employing a combination of historical policy research, critical literature review, and an analysis of secondary data, the chapter provides a chronology of the development of the Economic Community of West African States’ (ECOWAS) Protocol on Free Movement. This is done within the context of how the implementation of the Protocol facilitate human mobility and regional integration. The chapter pays attention to how the provision of the Protocol enables citizens of the West African region to take advantage of the opportunities in member states, and further explores some of the major challenges in the implementation of the Protocol. The chapter shows that the protocol on free movement allows ECOWAS citizens to continue to travel without visas within the region. Free movement of persons in the region has yielded great economic benefits in terms of boosting intra-regional trade, supporting the livelihoods of Community citizens and increasing remittance flows within the region. Nevertheless, there are still challenges associated with extortion and harassment of migrants at border crossings, and a lack of coherence between the member state national laws and the ECOWAS Protocols has meant that protocol is yet to be fully realised. The chapter also presents analysis of the prospects of recent attempts at strengthening the protocol such as the proposal to lift the provision/restriction that allows/limits member states’ citizens to enter and stay for maximum of 90 days and the proposal for the establishment of a common social security across the region.
International Migration, Diaspora Investments and Development in Nigeria
Authors: Akanle Olayinka , Ola-Lawson Olayinka Damilola 
Published: July 2022

AbstractGovernments and development stakeholders pay great attention to issues surrounding international migration because they are of great concern not only to destination countries but also transit and countries of origin. Strategic issues relative to international migration are human loss, insecurity, migrant smuggling, kidnapping, criminal networks, health, integration and border management among others. Noteworthy is the lack of consensus on management approaches and consequences of international migration among stakeholders, particularly migrant sending and receiving countries. There is, however, a measure of agreement that international migrants have the capacity to contribute to development of poor countries and West Africa comes to focus in this instance. Two perspectives exist relative to diaspora’s/international migrants’ contribution to development: the celebratory perspective and the pessimistic perspective. This chapter, therefore, examines the profile of diaspora investments, challenges and coping mechanisms of the diaspora relative to investments and the influence of the diaspora’s investments on development through a Nigerian case study. This chapter is within the intellectual and pragmatic frameworks of intersectionalities of international migration, the diaspora and development in West Africa. Data for this chapter was gathered in Nigeria from 2019 to 2020. The findings suggest that the diaspora engages in many different investments for various reasons but not without nearly prohibitive challenges. They have, however, innovated strategic coping mechanisms with creative contributions to development through investments within critical checkered experiences needing multi-level attention from states and non-state actors for sustainability.
Collective and Leadership
Authors: Tipurić Darko 
Published: July 2022

AbstractThe chapter argues that leadership is an inseparable feature of the collective. The central concepts presented in the chapter are collective, collective intentionality, and collective action. The chapter calls for a discussion of the following questions: What is the connection between collective intentionality and collective action? How are courses of action developed, and how are the actions of collective members combined and aligned? How do ideas, symbols and narratives come together to form shared meanings in the collective? Which obstacles need to be removed in order for the collective to be capable of coherent and integrated action? What is the role of leadership in all this? The chapter also aims to provide a more comprehensive understanding of the similarities and differences between the concepts of leadership and management.

A Framework for Investigating Microdata Quality, with Application to South African Labour Market Household Surveys
Authors: Daniels Reza Che 
Published: July 2022

AbstractThis chapter identifies a framework for investigating microdata quality that is particularly useful to researchers working with public-use micro datasets where limited information about the data quality protocols of the survey organisation are present. It then utilises this framework to investigate South African labour market household surveys from the mid 1990s to 2007. In order to develop the framework, we rely on the total survey error (TSE) framework to articulate the forms of statistical imprecision that exist in any public-use dataset. The magnitudes of statistical imprecision are largely dependent on the efficacy of the survey organisation’s data quality control protocols, which are, in turn, affected by human resource and budget constraints.
Univariate Multiple Imputation for Coarse Employee Income Data
Authors: Daniels Reza Che 
Published: July 2022

AbstractEmployment income data are coarsened as a result of questionnaire design. In the previous chapter we saw that Statistics South Africa (SSA) ask two employment income questions: an exact income question with a showcard follow-up. In public-use datasets, this results in two income variables: a continuously distributed variable for exact income responses and a categorical variable for bounded income responses with separate categories for nonresponse. It is the task of the researcher to then generate a single income variable that effectively deals with this mixture of data types. Following Heitjan and Rubin (1991), we call a variable with this mixture of data types “coarse data”.

Homogenization and Low Mach Number Limit of Compressible Navier-Stokes Equations in Critically Perforated Domains
Authors: Bella Peter , Oschmann Florian 
Published: July 2022

AbstractIn this note, we consider the homogenization of the compressible Navier-Stokes equations in a periodically perforated domain in$${{\,\mathrm{{\mathbb {R}}}\,}}^3$$R3. Assuming that the particle size scales like$$\varepsilon ^3$$ε3, where$$\varepsilon >0$$ε>0is their mutual distance, and that the Mach number decreases fast enough, we show that in the limit$$\varepsilon \rightarrow 0$$ε→0, the velocity and density converge to a solution of the incompressible Navier-Stokes equations with Brinkman term. We strongly follow the methods of Höfer, Kowalczyk and Schwarzacher [https://doi.org/10.1142/S0218202521500391], where they proved convergence to Darcy’s law for the particle size scaling like$$\varepsilon ^\alpha $$εαwith$$\alpha \in (1,3)$$α∈(1,3).

Notfälle aus Perspektive der Psychosozialen Akuthilfen – Die Arbeit von Kriseninterventionsteams
Authors: Hoppe Sebastian 
Published: July 2022

ZusammenfassungTeams der Krisenintervention und Notfallseelsorge füllen seit wenigen Jahrzehnten eine Versorgungslücke in der nichtpolizeilichen Gefahrenabwehr. Die Psychosozialen Akuthilfen (PSAH) als Teilbereich der Psychosozialen Notfallversorgung (PSNV) konzentrieren sich auf Angehörige und Hinterbliebene, Vermissende, Augenzeug*innen und Überlebende von belastenden Ereignissen und bieten unmittelbar ereignisbezogene psychosoziale Unterstützung an.Der Einsatz von Kriseninterventionsteams (KIT) findet inzwischen breite Akzeptanz und Anerkennung: Einsatzkräfte von KIT leisten auf Basis einer fundierten Ausbildung wichtige psychosoziale Unterstützung, die klaren Leitlinien folgt. Qualitätssicherung, gesetzliche Grundlagen und die Frage der Finanzierung von PSAH werden die zentralen Themen des aktuellen Jahrzehnts sein.Der vorliegende Artikel gibt einen umfassenden Überblick über die Arbeit von KIT und beschreibt die Struktur, Handlungslogik und Ziele der PSAH. Fokus ist dabei die Darstellung der Einsatzabläufe und insbesondere der einzelnen Maßnahmen während der KIT-Betreuungen.
