Background

The burden to fight with Corona Virus Disease-19 (COVID-19) pandemic has lied to frontline health care workers that are putting themselves at a higher risk in the battle against the disease. This study aimed to assess the exposure health risks of COVID-19 among frontline healthcare workers in the Amhara region, Ethiopia.

Method

A web-based cross-sectional study was conducted on public health workers from May to August 2020. Data were collected using a structured questionnaire via email and telegram services. Both descriptive statistics and bivariate followed by multivariable logistic regression analyses were conducted to identify distribution patterns and factors associated with exposure risks to COVID-19. Odds ratio with 95% Confidence Interval (CI), and a P-value of <0.05 was used to determine statistical significance.

Result

A total of 418 health care workers participated in the study with a response rate of 99.1%. The majority of the study participants 310(74.2%), were males, and 163(39%) were nurses/ midwives respectively. More than half of the respondents 237(56.7%), had reported that they didn`t have face-to-face contact with a confirmed COVID-19 patient. Among the respondents, 173(41.4%), 147(35.2%), 63(15.1%), and 65(15.6%) of the health professionals had always used gloves, medical masks, face shield, or goggles/protective glasses, and disposable gown, respectively. In this study, age between 25–34 years (AOR = 0.20), age between 35–44 years (AOR = 0.13), family size of >6 (AOR = 3.77), work experience of 21–30 years (AOR = 0.01), and good handwashing habit (AOR = 0.44) were the protective factors against COVID-19. On the other hand, perception of non-exposure to COVD 19 (AOR = 9.56), and poor habit of decontamination of high touch areas (AOR = 2.52) were the risk factors associated with confirmed COVID 19 cases among health care workers.

Conclusion

Poor adherence to personal protective equipment use and aseptic practices during and after health care interactions with patients were identified. Strategies should be implemented to institute effective and sustainable infection control measures that protect the health care workers from COVID-19 infection.
Prophages integrating into prophages: A mechanism to accumulate type III secretion effector genes and duplicate Shiga toxin-encoding prophages in Escherichia coli
Authors: Nakamura Keiji , Ogura Yoshitoshi , Gotoh Yasuhiro , Hayashi Tetsuya
Published: April 2021

Bacteriophages (or phages) play major roles in the evolution of bacterial pathogens via horizontal gene transfer. Multiple phages are often integrated in a host chromosome as prophages, not only carrying various novel virulence-related genetic determinants into host bacteria but also providing various possibilities for prophage-prophage interactions in bacterial cells. In particular, Escherichia coli strains such as Shiga toxin (Stx)-producing E. coli (STEC) and enteropathogenic E. coli (EPEC) strains have acquired more than 10 prophages (up to 21 prophages), many of which encode type III secretion system (T3SS) effector gene clusters. In these strains, some prophages are present at a single locus in tandem, which is usually interpreted as the integration of phages that use the same attachment (att) sequence. Here, we present phages integrating into T3SS effector gene cluster-associated loci in prophages, which are widely distributed in STEC and EPEC. Some of the phages integrated into prophages are Stx-encoding phages (Stx phages) and have induced the duplication of Stx phages in a single cell. The identified attB sequences in prophage genomes are apparently derived from host chromosomes. In addition, two or three different attB sequences are present in some prophages, which results in the generation of prophage clusters in various complex configurations. These phages integrating into prophages represent a medically and biologically important type of inter-phage interaction that promotes the accumulation of T3SS effector genes in STEC and EPEC, the duplication of Stx phages in STEC, and the conversion of EPEC to STEC and that may be distributed in other types of E. coli strains as well as other prophage-rich bacterial species.

Ganged Up On: How the US immigration system penalises and fails to protect Central American minors who are trafficked for criminal activity by gangs
Authors: Soltis Katherine , Taylor Diaz Madeline
Published: April 2021

This article addresses the failures of the United States immigration system to protect Central American minors who were trafficked for exploitation in criminal activities by gangs. In particular, it focuses on the ways in which the US immigration system denies humanitarian protection to Central American minors who were forced to participate in criminal activity by the Mara Salvatrucha (MS-13) and 18th Street gangs, and instead detains them. The article will examine this trend in the context of a larger proclivity to criminalise immigration in the US, particularly minors fleeing violence in Central America. We draw upon our experience representing Central American minors in their applications for humanitarian immigration relief to highlight how the US immigration system fails to protect this vulnerable population and penalises these children for their own victimisation.

Authors: Boto Xavier Laís , Das Chagas do Nascimento Jr Francisco , Chiapetti Jorge
Published: April 2021

O presente trabalho trata das novas dinâmicas de especialização da produção de cacau no Sul do estado da Bahia. Desde a chamada “crise do cacau”, pôde-se observar a disseminação de novas formas de produção de amêndoas na região, dentre as quais se destaca a produção de cacau orgânico certificado. Tal modelo de produção alinha-se ao fenômeno de descomoditização da produção agrícola, o qual possui como característica a valorização de formas específicas de produção local, o fortalecimento da identidade dos produtores e, no caso do Sul Baiano, se estabeleceu como estratégia para superar a crise vivenciada pela região desde o final da década de 1980. Através de pesquisa empírica, avaliou-se as atividades desenvolvidas pela Cooperativa Cabruca e pela Rede Povos da Mata, organizações que atuam no apoio à produção de cacau orgânico certificado no Sul Baiano. O intuito de analisar aquelas diferentes organizações, foi averiguar em que medida a adoção de modelos distintos de certificação da produção orgânica (a certificação por auditoria e a certificação participativa) possibilita aos agricultores alcançarem maior autonomia econômica e, a região, tornar-se menos subordinada ao mercado de commodities. Finalmente, concluiu-se que apesar dos obstáculos existentes para pequenos e médios produtores obterem a certificação, a construção de articulações locais permitem aos mesmos se inserirem, paulatinamente, nos circuitos espaciais de produtos certificados.

Pericardial Access Through the Right Atrium in a Porcine Model
Authors: Kamat Ishan , Cohn William E.
Published: April 2021

As procedures such as epicardial ventricular ablation and left atrial appendage occlusion become more commonplace, the need grows for safer techniques to access the physiologic pericardial space. Because this space contains minimal fluid for lubrication, prevailing methods of pericardial access pose considerable periprocedural risk to cardiac structures. Therefore, we devised a novel method of pericardial access in which carbon dioxide (CO2) is insufflated through a right atrial puncture under fluoroscopic guidance, enabling clear visualization of the cardiac silhouette separating from the chest wall. We performed the procedure in 8 Landrace pigs, after which transthoracic percutaneous pericardial access was obtained by conventional means. All of the animals remained hemodynamically stable during the procedure, and none showed evidence of epicardial or coronary injury. The protective layer of CO2 in the pericardial space anterior to the heart facilitated percutaneous access in our porcine model, and the absence of complications supports the potential safety of this method.

The rapid growth of Internet technologies and availability of web tools created an opportunity to develop a robust and user-friendly web service model for medical care, and it demands urgent solutions as the uncertainty of disease spread threaten humanity. With changing Quality of Service principles, many existing web services need to offer specific medical services that suit practical needs. The provision of an effective service selection and recommendation features that best meet the user's requirements will be able to improve the quality of web service model. The Quality of Service metrics should be calculated and analyzed before optimizing a recommendation technique. Evaluation therefore forms an important part of the process for designing and implementing recommendation systems. Further, predicting Quality of Service indicators accurately from historical background dataset under complex scenarios and combination of conditions is useful. In this perspective, lots of web service methods are studied, and this paper presents our comprehensive analysis mainly focusing on the development of better web service based framework for medical applications.

Library management is a center controlling libraries in a digital era. Libraries need creative managers to get power in carrying out planning, implementation, evaluation, and follow-up using a psychopragmatic perspective. The problems are (1) how creative library management in the digital era in Indonesia is, (2) how to strengthen librarians’ competencies in managing a creative library in the digital era, (3) how to create creative strategies and information technology-based innovation in managing creative libraries in Indonesia, and (4) how the effort of creative library management in understanding characteristics and objectives of library users using the psychopragmatic approach. The method was descriptive qualitative with the psychopragmatic approach. The data collection techniques used interviews, observation, and active participation to obtain the data. They were then analyzed by interactive techniques, in terms of a deductive technique to answer research problems. The result indicates that (1) the creative library management of digital era in Indonesia regarding psychopragmatic perspective is necessarily started by changing library managers’ and librarians’ mindset, (2) strengthening librarians’ soft skills is considered significant in this management, (3) this management certainly needs information technology-based creativity and innovation to provide various information literacies, and (4) this management needs psychopragmatic approach. Therefore, the creative library management in the digital era in Indonesia based on the psychopragmatic perspective is actualized and useful for librarians to support the acceleration of information and knowledge literacies in the industrial revolution 4.0 era.

Published: April 2021

Providing authentic learning experiences is a stellar teaching and learning strategy to prepare students for their future careers. They cultivate and enhance students learning by providing hands- on, experiential learning opportunities. However, incorporating such activities can be challenging, logistically complicated and may encapsulate hazardous situations and safety concerns. When these challenges arise, Virtual and Augmented Reality can offer learning experiences to supplement the curriculum, and optimise the valuable time spent on location. This paper provides an overview of different pedagogical applications to incorporate virtual experiences, namely Virtual experiences to supplement and optimise real-world experiences; Simulations and virtual tours for inaccessible or remote locations; First-person point-of-view; and Virtual scenarios for dangerous situations, which is supported with examples of activities used in higher education.

Nachbildung von Phasenschiebereffekten durch Stromquellen
Authors: Gebhardt Marc , Wolter Martin
Published: April 2021

Die steigende Distanz von Erzeugung und Verbrauch in elektrischen Übertragungsnetzen zieht die Notwendigkeit einer transparenten Leistungsflusssteuerung nach sich. Zur Steuerung von Leistungsflüssen lassen sich unter anderem Phasenschiebertransformatoren (PST) einsetzen, wie es auch schon in mehreren Gebotszonen des europäischen Verbundnetzes an zahlreichen Stellen geschehen ist. Die Abbildung der Einflüsse der einzelnen PST auf den Leistungsfluss im Netz lässt sich bisher nur durch linearisierte Gleichstrom-Leistungsfluss-Annahmen vornehmen. In diesem Beitrag wird eine Methode dargestellt, die ohne DC-Annahmen die Berechnung von PST-Einflüssen ermöglicht. Dazu wird jeder PST durch zwei Stromquellen nachgebildet und darauf basierend werden für jeden PST einzeln die Flüsse im Netz berechnet.

On the socles of characteristically inert subgroups of Abelian p-groups
Authors: Chekhlov Andrey R. , Danchev Peter V. , Goldsmith Brendan
Published: April 2021

We define the notion of a characteristically inert socle-regular Abelian p-group and explore such groups by focussing on their socles, thereby relating them to previously studied notions of socle-regularity. We show that large classes of p-groups, including all divisible, totally projective and torsion-complete p-groups, share this property when the prime p is odd. The present work generalizes notions of full inertia intensively studied recently by several authors and is a development of a recent work of the authors published in Mediterranean J. Math. (2021).
A novel transient search optimization for optimal allocation of multiple distributed generator in the radial electrical distribution network
Authors: Bhadoriya Jitendra Singh , Gupta Atma Ram
Published: April 2021

Most of the generated electricity is lost in power loss while transmitting and distributing it to the consumer end. The power losses occurring in the distribution network cause deviation in voltage and lower stability due to increased load demand. The integration of multiple Distributed Generation (DG) will enable the existing radial electrical distribution network efficient by minimizing the power losses and improving the voltage profile. Metaheuristic optimization techniques provide a favorable solution for optimal location and sizing of DG in the distribution network. A novel modern metaheuristic Transient Search Optimization (TSO) algorithm, inspired by the electrical network’s transient response of storage components implemented in the proposed work. The TSO formulated optimal DGs allocation to minimize total active power loss, voltage deviation and enhance voltage stability index as minimization optimization problem satisfying various equality and inequality constraints. The installation of multiple DG units at unity, fixed, and optimal power factors were examined. The TSO algorithm’s effectiveness was tested on standard IEEE 33-bus and 69-bus radial distribution networks, including various operating events developed in the form of single and multi-objective fitness functions. The active power loss reduced to 94.29 and 94.71% for IEEE 33 and 69 bus distribution systems. The obtained results trustworthiness is confirmed by comparison with well-known optimization methods like Genetic Algorithm (GA), Particle Swarm Optimization (PSO), combined GA/PSO, Teaching Learning Based Algorithm (TLBO), Swine influenza model-based optimization with quarantine (SIMBO-Q), Multi-Objective Harris Hawks optimizer (MOHHO) and other provided in the literature. The presented numerical studies represent the usefulness and out-performance of the proposed TSO algorithm due to its exploration and exploitation optimization mechanisms for the DG allocation problem meticulously.
An intelligent approach towards very short-term load forecasting
Authors: Pati Uttamarani , Ray Papia , Singh Arvind R.
Published: April 2021

Very short term load forecasting (VSTLF) plays a pivotal role in helping the utility workers make proper decisions regarding generation scheduling, size of spinning reserve, and maintaining equilibrium between the power generated by the utility to fulfil the load demand. However, the development of an effective VSTLF model is challenging in gathering noisy real-time data and complicates features found in load demand variations from time to time. A hybrid approach for VSTLF using an incomplete fuzzy decision system (IFDS) combined with a genetic algorithm (GA) based feature selection technique for load forecasting in an hour ahead format is proposed in this research work. This proposed work aims to determine the load features and eliminate redundant features to form a less complex forecasting model. The proposed method considers the time of the day, temperature, humidity, and dew point as inputs and generates output as forecasted load. The input data and historical load data are collected from the Northern Regional Load Dispatch Centre (NRLDC) New Delhi for December 2009, January 2010 and February 2010. For validation of proposed method efficacy, it’s performance is further compared with other conventional AI techniques like ANN and ANFIS, which are integrated with genetic algorithm-based feature selection technique to boost their performance. These techniques’ accuracy is tested through their mean absolute percentage error (MAPE) and normalized root mean square error (nRMSE) value. Compared to other conventional AI techniques and other methods provided through previous studies, the proposed method is found to have acceptable accuracy for 1 h ahead of electrical load forecasting.

Published: April 2021

The purpose of this study was to investigate students’ behavior towards knowledge sharing and the factors, individual and classroom, affecting it. Quantitative research design was used to conduct this study. Students enrolled in engineering universities, located in three provinces (Punjab, Khyber Pakhtunkhwa, Sindh) and capital (Islamabad) of Pakistan, were the population of this study. Researchers collected the data through survey questionnaires. SPSS-22 was used to analyze the collected data and for testing the hypotheses. Results revealed that the majority of engineering students’ knowledge sharing behavior was positive. Findings proved that majority of individual and classroom related factors were affecting knowledge sharing behavior of Pakistani students significantly. This is the first study which investigated Pakistani 10 engineering category universities’ students’ behavior towards knowledge sharing and factors impacting it. Results contributed in the body of literature by advancing it regarding behavior towards knowledge sharing in the context of engineering students of Pakistan. The study’s findings can play a vital role in facilitating educational institutions, students, and academicians in understanding the factors impacting students’ knowledge sharing behavior. This, in turn, might help them in removing negatively influencing factors by taking essential measures and facilitating factors with positive impact to improve students’ knowledge sharingbehavior.
Hypocoristic truncation in Sardinian
Authors: Cabré Teresa , Torres-Tamarit Francesc , Vanrell Maria del Mar
Published: April 2021

This article focuses on hypocoristic truncation in Sardinian. Besides disyllabic truncation, hypocoristic truncation in Sardinian also yields trisyllabic truncated forms by means of a process of reduplicative prefixation (e.g.,Totore ← Servatore) and, more interestingly, a process of copy of what is analyzed as an internally layered ternary foot (e.g.,(Va(tore)) ← Servatore). In this paper we develop an OT analysis of hypocoristic truncation based on output-output correspondence relations between bases and truncated morphemes that gives further support to internally layered ternary feet in the domain of the phonology–morphology interface.
Ausbau der Datenerhebungsbefugnisse von Sicherheitsbehörden – Lässt die wissenschaftliche Empirie Chilling-Effekte in der Bevölkerung erwarten?
Authors: Moll Ricarda , Schneider Franziska
Published: April 2021

Aufgrund der kontinuierlichen Ausweitung von Datenerhebungsbefugnissen für Sicherheitsbehörden wird ein häufig als »Chilling« bezeichneter Effekt befürchtet. Demnach führt die Sorge über ein mögliches Überwachtwerden dazu, dass freiheitliche Grundrechte nicht mehr ausgeübt werden. In der Rechtswissenschaft ist die Existenz eines Chilling-Effekts bzw. das Ausmaß seiner Auswirkungen auf Verhaltensänderungen jedoch umstritten. Der vorliegende Artikel gibt einen Überblick über die empirische Evidenz zum Chilling-Effekt. Hinzugezogen werden im ersten Teil Befunde aus verschiedenen Paradigmen und Traditionen, die den Chilling-Effekt nicht explizit untersuchen, jedoch Hinweise auf die dahinterstehenden Mechanismen geben (Asch-Paradigma, Watching Eyes-Paradigma, Befunde aus der Forschung zur Wirkung von Sicherheitskameras im öffentlichen Raum). Einschränkungen in der Übertragbarkeit der Ergebnisse werden jeweils diskutiert. Im zweiten Teil werden Untersuchungen skizziert, die den Chilling-Effekt direkt in Online-Kontexten untersuchen, wobei die methodischen Probleme der verschiedenen Ansätze diskutiert werden. Wir beleuchten abschließend die empirische Evidenz zu Argumenten, die häufig als Gegenbeweise zur Existenz von Chilling-Effekten angeführt werden. Wir kommen zu dem Ergebnis, dass es sich verdichtende Hinweise auf die Existenz eines Chilling-Effekts aufgrund von Datenerhebungsbefugnissen gibt, jedoch weitere empirische Forschung notwendig ist.
Reduction principle at work
Authors: Pötzsche Christian , Russ Evamaria
Published: April 2021

The purpose of this informal paper is three-fold: First, filling a gap in the literature, we provide a (necessary and sufficient) principle of linearized stability for nonautonomous difference equations in Banach spaces based on the dichotomy spectrum. Second, complementing the above, we survey and exemplify an ambient nonautonomous and infinite-dimensional center manifold reduction, that is Pliss’s reduction principle suitable for critical stability situations. Third, these results are applied to integrodifference equations of Hammerstein- and Urysohn-type both in C- and Lp
-spaces. Specific features of the nonautonomous case are underlined. Yet, for the simpler situation of periodic time-dependence even explicit computations are feasible.

Objective

Large birth size programs an elevated risk of type 2 diabetes in adulthood, but data are absent concerning glucose metabolic health impact in infancy. We sought to determine whether the large birth size is associated with insulin resistance and β-cell function in infancy and evaluate the determinants.

Design and participants

In the Canadian 3D birth cohort, we conducted a nested matched (1:2) study of 70 large-for-gestational-age (LGA, birth weight >90th percentile) and 140 optimal-for-gestational-age (OGA, 25th–75th percentiles) control infants. The primary outcomes were homeostasis model assessment of insulin resistance (HOMA-IR) and beta-cell function (HOMA-β) at age 2-years.

Results

HOMA-IR and HOMA-β were similar in LGA and OGA infants. Adjusting for maternal and infant characteristics, decelerated growth in length during early infancy (0–3 months) was associated with a 25.8% decrease (95% confidence intervals 6.7–41.0%) in HOMA-β. During mid-infancy (3–12 months), accelerated growth in weight was associated with a 25.5% (0.35–56.9%) increase in HOMA-IR, in length with a 69.3% increase (31.4–118.0%) in HOMA-IR and a 24.5% (0.52–54.3%) increase in HOMA-β. Decelerated growth in length during late infancy (1–2 years) was associated with a 28.4% (9.5–43.4%) decrease in HOMA-IR and a 21.2% (3.9–35.4%) decrease in HOMA-β. Female sex was associated with higher HOMA-β, Caucasian ethnicity with lower HOMA-IR, and maternal smoking with lower HOMA-β.

Conclusions

This study is the first to demonstrate that large birth size is not associated with insulin resistance and β-cell function in infancy but infancy growth pattern matters. Decelerated infancy growth may be detrimental to beta-cell function.
Apoplexy of microprolactinomas during pregnancy: report of five cases and review of the literature
Authors: Kuhn Emmanuelle , Weinreich Alexandra A , Biermasz Nienke R , Jorgensen Jens Otto L , Chanson Philippe
Published: April 2021

Context

Prolactinomas frequently cause amenorrhoea, galactorrhoea and infertility and require dopamine agonist (DA) treatment to normalize prolactin levels and hence, restore ovulation. The vast majority of female patients harbour microprolactinomas in whom DA treatment is usually discontinued at the time of pregnancy diagnosis and surveillance is generally limited as the symptomatic growth is considered very rare.

Case descriptions

We report five cases of women harbouring a microprolactinoma in whom symptomatic pituitary apoplexy occurred during pregnancy. Only one necessitated surgery during pregnancy, while the others were treated conservatively by reintroducing DAs in three. A systematic literature review found reports of four additional cases among 20 cases of prolactinomas (both macro- and micro-prolactinomas) complicated by apoplexy during pregnancy.

Conclusion

During pregnancy, pituitary apoplexy may occur in pre-existing microprolactinomas, causing tumour enlargement and headache, which may be self-limiting but may require intervention by re-initation of dopamine agonists or surgery. Our literature review confirms that this clinical event is rare; nevertheless, physicians managing pregnant patients with microprolactinomas must be aware that symptomatic pituitary apoplexy may incidentally occur in all trimesters of pregnancy and require prompt radiological, endocrine and ophthalmological assessment and treatment.

Patients may experience long-term physical, psychological and cognitive impairment after intensive care unit (ICU) discharge, a condition commonly described as post-intensive care syndrome. The relative contribution of each of these components to long-term quality of life was never investigated.

The aim of this studyis to identify the type and severity of disability and QoL at the discharge from ICU and up to following 6 months.

Material and Methods. All patients (n=218) discharged from a university hospital ICU between April 2016 and July 2017 were eligible. Exclusion criteria included: age <18 years, brain or spinal injury, life expectancy <90 days, and ICU stay <12 hours. The Short Form Health Survey (SF-36), and 5-level EuroQoL-5D (EQ-5D-5L) questionnaires were administered at ICU discharge, and at 30-, 90- and 180-days. We compared patients requiring short-term ICU monitoring (IM, Intensive Monitoring,n=109) or patients requiring ICU treatment (IT, Intensive Treatment,n=109).

Results. All dimensions of SF-36 and EQ-5D-5L parameters increased from ICU discharge to 180-days, except for the SF-36 Synthetic index linked to mental health (P=0.08). All EQ-5D-5L parameters improved significantly in the IT group, while only Visual Analog Scale Health Perception improved in the IM group.

Conclusion. ICU survivors suffer long-term physical and psychological sequelae. The perception of Quality of Life is reduced after ICU discharge. The psychological and cognitive dimensions were more compromised than physical ones. Patients discharged from the ICU may benefit from specific intensive care follow-up clinics addressing their needs in term of psychological and cognitive support.
