Trends in Hidradenitis Suppurativa Disease Severity and Quality of Life Outcome Measures: Scoping Review
Authors: Maghfour Jalal , Sivesind Torunn Elise , Dellavalle Robert Paul , Dunnick Cory
Published: September 2021

Background

Although there has been an increase in the number of randomized controlled trials evaluating treatment efficacy for hidradenitis suppurativa (HS), instrument measurements of disease severity and quality of life (QoL) are varied, making the compilation of data and comparisons between studies a challenge for clinicians.

Objective

We aimed to perform a systematic literature search to examine the recent trends in the use of disease severity and QoL outcome instruments in randomized controlled trials that have been conducted on patients with HS.

Methods

A scoping review was conducted in February 2021. The PubMed, Embase, Web of Science, and Cochrane databases were used to identify all articles published from January 1964 to February 2021. In total, 41 articles were included in this systematic review.

Results

The HS Clinical Response (HiSCR) score (18/41, 44%) was the most commonly used instrument for disease severity, followed by the Sartorius and Modified Sartorius scales (combined: 16/41, 39%). The Dermatology Life Quality Index (18/41, 44%) and visual analogue pain scales (12/41, 29%) were the most commonly used QoL outcome instruments in HS research.

Conclusions

Randomized controlled trials conducted from 2013 onward commonly used the validated HiSCR score, while older studies were more heterogeneous and less likely to use a validated scale. A few (6/18, 33%) QoL measures were validated instruments but were not specific to HS; therefore, they may not be representative of all factors that impact patients with HS.

Published: September 2021

UNSTRUCTURED

Early decisions relating to the implementation of virtual care relied on necessity and clinical judgement, but there is a growing need for the generation of evidence to inform policy and practice designs. The need for stronger partnerships between researchers and decision-makers is well recognized, but how these partnerships can be structured and how research can be embedded alongside existing virtual care initiatives remain unclear. We present a series of case studies that illustrate how embedded research can inform policy decisions related to the implementation of virtual care, where decisions are either to (1) discontinue (red light), (2) redesign (yellow light), or (3) scale up existing initiatives (green light). Data were collected through document review and informal interviews with key study personnel. Case 1 involved an evaluation of a mobile diabetes platform that demonstrated a mismatch between the setting and the technology (decision outcome: discontinue). Case 2 involved an evaluation of a mental health support platform that suggested evidence-based modifications to the delivery model (decision outcome: redesign). Case 3 involved an evaluation of video visits that generated evidence to inform the ideal model of implementation at scale (decision outcome: scale up). In this paper, we highlight the characteristics of the partnership and the process that enabled success and use the cases to illustrate how these characteristics were operationalized. Structured communication included monthly check-ins and iterative report development. We also outline key characteristics of the partnership (ie, trust and shared purpose) and the process (ie, timeliness, tailored reporting, and adaptability) that drove the uptake of evidence in decision-making. Across each case, the evaluation was designed to address policy questions articulated by our partners. Furthermore, structured communication provided opportunities for knowledge mobilization. Structured communication was operationalized through monthly meetings as well as the delivery of interim and final reports. These case studies demonstrate the importance of partnering with health system decision-makers to generate and mobilize scientific evidence. Embedded research partnerships founded on a shared purpose of system service provided an effective strategy to bridge the oft-cited gap between science and policy. Structured communication provided a mechanism for collaborative problem-solving and real-time feedback, and it helped contextualize emerging insights.

Authors: Ramos Patricia Maloso , Pedrão Mayka R. , Bell Lindsey C. , Scheffler Tracy L.
Published: September 2021

Muscle properties and metabolism influence muscle to meat conversion. Fiber type profile impacts glycolytic capacity as well as protein turnover rate in vivo. Our objective was to investigate protease content and activation during the early postmortem period using muscles with known divergent metabolism. Samples from longissimus lumborum (LL) and diaphragm (Dia) were taken from predominantly Angus steer carcasses (n = 6) at 1, 3, and 24 h postmortem and frozen. Myosin heavy chain (MyHC) isoforms, ATP, glycogen, glucose, glucose-6-phosphate (G6P), and lactate concentrations were determined. Procaspase-3, calpain-1, calpastatin, desmin, and troponin-T were assessed by immunodetection. Muscles showed contrasting MyHC profiles, with LL represented primarily by IIx and IIa isoforms (∼88%) whereas Dia contained mostly (80%) type I isoform. Glycogen degradation was more pronounced in LL and coincided with more rapid accumulation of glucose and lactate (P < 0.01). Procaspase-3 content was influenced by muscle (m: P < 0.01), being greater in Dia. Fragments indicating activation of procaspase-3 postmortem were not detected. Calpain-1 autolysis and intact calpastatin (135 kDa) content were influenced by muscle and time (m × t: P < 0.01 and P < 0.01, respectively). Calpastatin fragmentation postmortem was not associated with greater procaspase-3 content. In conclusion, fast glycolytic LL displayed faster protease activation and greater proteolysis during the first 24 h postmortem.

Published: September 2021

Abstract: Urbanization may be a process having a serious impact ashore use characteristics. Basically, as an impression of urbanization, the world is observed with rapid change within the land use character of agricultural land. Generally, the agricultural land is employed for various development activities like industrial establishments, residential colonies and other urban infrastructure during the method of urbanization. it's necessary to possess a periodical assessment of land use change for the developing populated area , which helps to make a decision the longer term expansion strategies for the world. Nashik city is located in the state of Maharashtra in the western part of India. It is one of the most dynamic cities of India with a rapid growth rate due to migration from various parts of Maharashtra. The Nashik city is presently spread over an area of 264.15 sq. km. with a periodical increase in municipal corporation boundary during the last few decades. As a result of urbanization and expansion of municipal corporation limits, the city has undergone drastic changes in land use character. In this study, land-use change is quantified for the existing six zones of Nashik city during the last 30 years using remote sensing and GIS. The study has analysed the relationship between urban expansion and the loss of agricultural land because of an increase in a built-up area and other land use. The study present excellent scenario for land use change during the year 1991, 2001, 2011 and 2020. This can surely guide the development strategies for the study area of Nashik. Also the study can be extended for conducting a suitability analysis to assess future change of land use based on various criteria.

Abstract: Geosynthetics are with success used for many years within the construction of roads. They fulfill most classical perform like separation, protection, filtration, Drainage, sealing, and reinforcement. In recent time the scope of application has been extended considerably by the development of road pavement. Field evidences indicate that geosynthetic reinforcements will improve pavement performance by avoiding cracking, rutting, and patholes & by reducing deflection of paved surface. The rise in urbanization crystal rectifier to the inadequacy of the land for building, because of that land with high water content and low bearing capability had to be used. within the past history numerous|many alternative} strategies are projected thus on improve the unfavorable conditions prevailing in various locations like the locations with low bearing capability soil, water work conditions, land movements, etc. the appliance of geosynthetics has proved to be the foremost promising answer of all the alternatives. numerous forms of geosynthetics are wont to fulfill numerous functions like filtration, separation, drainage, reinforcement, mitigation of reflective cracks, by the utilization of one or combination of 2 or additional geosynthetics. This use of geosynthetics has conjointly contributed towards the goal of being one among the foremost economical and much applicable alternatives. This paper conjointly studies the characteristics and therefore the basic data of geosynthetics usually just in case of pavement like geotextile, geogrid, geonets, geomembrane, GCL Associate in Nursingd geo- composite having an unequivocal perform. It includes the comparison of the pavement made with the assistance of geosynthetics and therefore the standard pavements against numerous parameters like bearing capability, wetness content, economy, maintenance needed and therefore the life amount of the pavement. the utilization of geosynthetics is increasing at a awfully fast rate and is being accepted worldwide and therefore there rises the need for elaborate study.

Nominal exchange rates EUR/GRD and EUR/ITL in the context of leaving the euro zone by Greece and Italy
Authors:   Faculty of Economic Sciences, University of Warsaw, Poland, Dąbrowska-Gruszczyńska Katarzyna , Gruszczyński Marcin ,   Faculty of Economic Sciences, University of Warsaw, Poland
Published: September 2021

Aim/purpose – The aim of this paper is to present two cases of crises in Greece and Italy and to evaluate the shadow exchange rates of hypothetical new currencies (re)introduced after Grexit and Italexit. Design/methodology/approach – Both shadow exchange rates are estimated using speculative pressure index concept that emphasizes the importance of changes in foreign exchange reserves and interest rate differentials in the absence of an independent nomi- nal exchange rate. The research sample covers Greece in 1989-2020 and Italy in 1989- 2020. Findings – The research presented the estimation of shadow exchange rates EUR/GRD and EUR/ITL during the euro zone membership period. Leaving the euro area one can expect the following market rates: EUR/GRD 600 and EUR/ITL 1850. That would mean 75% depreciation and 5% appreciation to the current euro parities EUR/GRD 340.75, and EUR/ITL 1936.27, respectively. Research implications/limitations – After potential Grexit Greek authorities could expect significant nominal depreciation of a new currency (or should introduce it with a substantial discount). In the case of Italexit, the new currency would preserve its nomi- nal value. The limitations of the research methodology are: a long period of the analysis covers structural changes of financial markets, crisis events, political factors (e.g., QE programs). Originality/value/contribution – The originality of this approach lies in the combina- tion of two important economic concepts – the idea of shadow exchange rate and the index of speculative pressure. Combined together they help to prepare the methodology of shadow exchange rates evaluation for currencies that are currently in the common currency system (e.g., currency union). These results can help in economic and political discussions on effects of leaving the currency union. Keywords: nominal exchange rates, euro area, financial crises.

“We Are Not Foreigners”: Constructing Migrant Subjects through Korean Chinese Migrants’ Claims-Making in South Korea
Authors: Kim Yang-Sook , Chien Yi-Chun
Published: September 2021

In this paper, we approach citizenship as a claims-making process consisting of social construction practices that emerge from ongoing negotiations and contestations. We examine the migrant subject-making process of Korean Chinese migrants in South Korea. We draw on the voices of migrants to discuss how Korean Chinese construct their migrant subjectivity by mobilizing a collective understanding of ethnonational belonging and thereby deploy distinctive strategies to support their claims. Our analysis of the data gathered from ethnographic observations and interviews with Korean Chinese migrant workers, activists, South Korean bureaucrats, and policymakers show that Korean Chinese migrants have called upon blood ties and ethnic affinity, continued allegiance, economic contributions, and human rights to construct themselves as legitimate candidates for citizenship in South Korea. By shifting our analytical focus from the state to the migrant subjectivity that emerges through day-to-day negotiations, we aim to unpack the complicated dynamics of social constructions of citizenship.

Autoritarismo e esperança: costurando fios entre Paulo Freire e José Cardoso Pires
Authors: Nogueira Gabriela Medeiros , Arriada Eduardo , Vahl Mônica Maciel
Published: September 2021

O presente artigo analisa o romance - O Delfim – do escritor português, José Cardoso Pires, a partir de Paulo Freire, considerando os conceitos: autoritarismo, esperança, situação-limite e inédito-viável. O cruzamento entre literatura, filosofia e educação tem possibilitado uma maior compreensão das relações sociais e conflitivas da sociedade, ampliando assim, o espectro de análise e de reflexões. No romance analisado, os moradores de Gafeira - aldeia ficcional em que a história é ambientada - vivem em um estado inerte, sonolento, de tempo imóvel e, até mesmo, opressivo. A ocorrência de um crime, muda os rumos da história e altera a ordem das relações sociais. Estabelecendo uma metáfora com a lagartixa, o escritor/narrador mostra a impermanência daquilo que parecia consolidado, ou seja, as relações de poder estabelecidas entre a aristocracia e o campesinato se desfazem. Operando com as categorias freirianas: consciência ingênua, opressor/oprimido, e com diversos aspectos abordados no romance, evidencia-se que a organização coletiva e a conscientização dos “desocupados” permitem a superação da condição de oprimidos. A criação da Cooperativa dos Noventa e Oito, é exemplo um concreto disso. O texto demonstra que as obras de Pires e Freire, mesmo com linguagens distintas, experiências diferentes e realidades distantes, elucidam formas de opressão e estruturas de poder, desvelam as máculas, as violências e os abusos por parte das elites.

The Effects of Exchange Rates on Zimbabwe’s Exports
Authors: Chimhore Mable , Chivasa Shynet
Published: September 2021

The study reviewed the effect of exchange rates on exports in Zimbabwe using the Ordinary Least Squares (OLS) technique. The objective of the study was to examine the effects of exchange rate on export growth in Zimbabwe using mainly the multicurrency era data. This is because the exchange rate plays a key role in policy formulation and implementation. The study is significant as understanding the role of exchange rate on export guides policymakers in coming up with the right policy mix to stimulate exports. Using secondary data from ZIMSTAT and World Bank, obtained results from a robust regression showed that South Africa’s exchange rates (SAEXRT) were weakly significant at 10%, South Africa broad money supply (SAM2) was significant at 5% and imports (DDIMP) were important to Zimbabwe’s export growth at 1% level of significance. To increase exports, there is a need for policy shift, shifting from overly focusing on foreign direct investment and increasing gross domestic product (GDP) because empirical results showed that FDI and gross domestic product were not significant in the model. Policies such as trade cooperation between South Africa and Zimbabwe may increase exports given the impact of South Africa's broad money supply on Zimbabwe’s exports.

Published: September 2021

In Latvia, during the COVID-19 pandemic teachers represent one of the professions with a special role in solving the problems caused by the crisis. It is important to provide the highest possible quality of education during the state-of-emergency, despite the increased risks of COVID-19 what teachers face while work in a classroom. The workload of teachers has increased and for many of them working conditions have deteriorated. Multiple factors pose a risk to the quality of work-life in general. The aim of the paper is to find out the teachers’ opinions on the factors influencing their quality of work-life, comparing the situation in the regions of Latvia, and to develop proposals for strengthening social dialogue to improve teachers’ quality of work-life. In February 2021, the Latvian Trade Union of Education and Science Employees conducted a survey “Teachers’ Salaries, Principles of Workload Formation and Risks of Professional Burnout”, in which 10 077 teachers were surveyed to study various aspects of their quality of work-life. The results revealed differences between regions in the teachers’ assessment of their quality of work-life and the factors influencing it. The quality of work-life of teachers has decreased, comparing to the situation a year and five years ago. Significantly that 9 out of 10 respondents did not feel cared for at the national level. The authors conclude that it is crucial to improve the social dialogue between the state institutions, employers and employees in order to increase the quality of teachers’ work-life.

Published: September 2021

The COVID-19 pandemic has affected the way people work and learn in unprecedented ways. Also, the pandemic has moved more business activity online, increasing the need for training and prompting them to build more online trainings. In this time of crisis, a suitable response requires novel ways to enable interaction between adult learners, adult learners and teachers, adult learners and content using online tools so that no one is left behind. In the context of regional development, online adult learning provides economic active inhabitants with wide opportunities since employees are able to attend high-quality trainings regardless the place of residence. In context of COVID-19, during the emergency situation Latvia has fully moved to remote learning, including adult learning. Educational institutions as well as enterprises that organise trainings for adults have to implement remote learning using several online tools. The aim of the paper is to analyse the main challenges of the adult learning sector in Latvia in context of COVID-19 taking into consideration the regional development issues. In order to achieve the aim, following research methods have been used: scientific literature studies, statistical data analysis, interviews. Main results of the survey: in case of Latvia, the Ministry of Education and Science of Republic of Latvia has launched several initiatives towards enabling the shift to online learning, providing recommendations, digital tools as well as good practice sharing. At the same time, there is no methodology and detailed step-by-step recommendations, how to develop the online education learning for educational institutions in Latvia. However, there are incentives to develop online adult learning via project funding.

En la presente investigación se evaluó la síntesis verde de nanopartículas de óxido de zinc (ZnO) y su aplicación como agente antibacteriano para sustratos textiles. El proceso de síntesis implicó el uso de extractos de Azadirachta indica, Aloe vera, y acetato de zinc como precursor metálico. La síntesis de nanopartículas se confirmó mediante espectrofotometría UV-Vis, espectroscopia de infrarrojo con transformada de Fourier (FTIR), difracción de rayos X (DRX) y microscopía electrónica de barrido. La eficiencia de las nanopartículas como agentes antibacterianos en textiles se probó en uno de 100 % algodón funcionalizado por impregnación. Este fue sometido a cinco y diez ciclos de lavado doméstico para analizar la durabilidad de las nanopartículas. La actividad antibacteriana del textil funcionalizado, con y sin ciclos de lavado, se determinó mediante la norma ISO 20743:2007 contra la bacteria Staphylococcus aureus ATCC 6538. Se encontró que las nanopartículas confieren una actividad antibacteriana fuerte al textil y, aunque hay una pérdida importante del nanomaterial con los ciclos de lavado, la concentración remanente es suficiente para mantener una actividad antibacteriana significativa hasta los diez ciclos de lavado. Se concluye que las nanopartículas de ZnO son candidatas promisorias para ser empleadas como agentes antibacterianos en la industria textil, pues presentan actividad antibacteriana y son relativamente fáciles de obtener por síntesis verde con extractos de A. indica y A. vera, material vegetal de fácil acceso en el departamento de Antioquia.

Numerical investigation of setup effects in the vertical holding capacity of finless torpedo anchors
Authors: Lopes G. , Sousa J. , Ellwanger G.
Published: September 2021

This article presents a numerical-based study on the vertical holding capacity of a typical finless torpedo anchor embedded in a pure cohesive isotropic sol considering setup effects. A strategy based on two axisymmetric nonlinear finite elements (FE) models is proposed. In these models, the soil is represented with continuous solid elements with both plane translational and pore pressure degrees of freedom, which allow the modeling of the soil's strength regain after the installation of the anchor, i. e., the soil setup. The anchor is also modeled with solid elements, and its interaction with the soil is addressed with contact elements. Several analyses are conducted to evaluate setup effects, and, additionally, a parametric study on different soil undrained shear strengths and permeability coefficients is performed. The results obtained show that the permeability of the soil and its undrained shear strength have an important role in the setup process, and an inverse relationship between consolidation time and the permeability coefficient of the soil is observed. Finally, an analytical approach is calibrated with a reasonable agreement to the numerical results
