Published: August 2021

Objective
To compare the psychometric performance of the Dermatology Life Quality Index (DLQI-BRA) and Skindex-16 to assess quality of life (QoL) in Brazilian patients with dermatological diseases.

Methods
This was a cross-sectional study carried out in a dermatology outpatient clinic of the São Paulo State University, with 188 patients with dermatological diseases. QoL was evaluated using the Dermatology Life Quality Index (DLQI-BRA) and Skindex-16. Cronbach’s alpha and Intraclass Correlation for Perfect Concordance (ICC) were used to analyse the reliability and temporal stability, respectively.

Results
A positive correlation was found between the total Skindex-16 score and DLQI-BRA (0.75). Both instruments showed a significant (p< 0.01) reduction in their scores at the second assessment, demonstrating that they were sensitive in detecting changes in responsiveness in cases where there was a clinical change. Cronbach alpha coefficients for the instruments showed satisfactory performance (>0,7), but Skindex-16 displayed the highest Cronbach alpha (0.94; CI = 0.93–0.95).

Conclusion
Both instruments tested showed a good psychometric performance assessing QoL in patients with skin dermatoses. The instruments displayed reliability and temporal stability as well as responsiveness.

Authors: Mohamed Nurul Azmawati , Solehan Hana Maizuliana , Mohd Rani Mohd Dzulkhairi , Ithnin Muslimah , Che Isahak Che Ilina 
Published: August 2021

Background
Coronavirus disease 2019 or COVID-19 is caused by a newly discovered coronavirus, SARS-CoV-2. The Malaysian government has planned to procure COVID-19 vaccine through multiple agencies and companies in order to vaccinate at least 70% of the population. This study aimed to determine the knowledge, acceptance and perception of Malaysian adults regarding the COVID-19 vaccine.

Methodology
An online survey was conducted for two weeks in December 2020. A bilingual, semi-structured questionnaire was set up using Google Forms and the generated link was shared on social media (i.e., Facebook and WhatsApp). The questionnaire consisted of questions on knowledge, acceptance and perception of COVID-19 vaccine. The association between demographic factors with scores on knowledge about COVID-19 vaccine were analysed using the Mann-Whitney test for two categorical variables, and the Kruskal-Wallis test used for more than two categorical variables.

Results
A total of 1406 respondents participated, with the mean age of 37.07 years (SD = 16.05) years, and among them 926 (65.9%) were female. Sixty two percent of respondents had poor knowledge about COVID-19 vaccine (mean knowledge score 4.65; SD = 2.32) and 64.5% were willing to get a COVID-19 vaccine. High knowledge scores associated with higher education background, higher-income category and living with who is at higher risk of getting severe COVID-19. They were more likely to be willing to get vaccinated if they were in a lower age group, have higher education levels and were female.

Conclusion
Even though knowledge about vaccine COVID-19 is inadequate, the majority of the respondents were willing to get vaccinated. This finding can help the Ministry of Health plan for future efforts to increase vaccine uptake that may eventually lead to herd immunity against COVID-19.

Published: August 2021

BackgroundLymphopenia is associated with various pathologies such as sepsis, burns, trauma, general anesthesia and major surgeries. All these pathologies are clinically expressed by the so-called Systemic Inflammatory Response Syndrome which does not include lymphopenia into defining criteria. The main objective of this work was to analyze the diagnosis of patients admitted to a hospital related to lymphopenia during hospital stay. In addition, we investigated the relationship of lymphopenia with the four levels of the Severity of Illness (SOI) and the Risk of Mortality (ROM).Method and findingsLymphopenia was defined as Absolute Lymphocyte Count (ALC) <1.0 x109/L. ALC were analyzed every day since admission. The four levels (minor, moderate, major and extreme risk) of both SOI and ROM were assessed. A total of 58,260 hospital admissions were analyzed. More than 41% of the patients had lymphopenia during hospital stay. The mean time to death was shorter among patients with lymphopenia on admission 65.6 days (CI95%, 57.3–73.8)vs89.9 (CI95%, 82.4–97.4), P<0.001. Also, patients with lymphopenia during hospital stay had a shorter time to the mortality, 67.5 (CI95%, 61.1–73.9)vs96.9 (CI95%, 92.6–101.2), P<0.001.ConclusionsLymphopenia had a high prevalence in hospitalized patients with greater relevance in infectious pathologies. Lymphopenia was related and clearly predicts SOI and ROM at the time of admission, and should be considered as clinical diagnostic criteria to define SIRS.
Pathophysiology of Takotsubo Cardiomyopathy: Reopened Debate
Authors: Angelini Paolo , Uribe Carlo , Tobis Jonathan M. 
Published: August 2021

Takotsubo cardiomyopathy (TTC), a persistently obscure dysfunctional condition of the left ventricle, is uniquely transient but nevertheless dangerous. It features variable ventricular patterns and is predominant in women. For 30 years, pathophysiologic investigations have progressed only slowly and with inadequate focus.
It was initially proposed that sudden-onset spastic obliteration of coronary flow induced myocardial ischemia with residual stunning and thus TTC. Later, it was generally accepted without proof that, in the presence of pain or emotional stress, the dominant mechanism for TTC onset was a catecholamine surge that had a direct, toxic myocardial effect.
We think that the manifestations of TTC are more dynamic and complex than can be assumed from catecholamine effects alone. In addition, after reviewing the recent medical literature and considering our own clinical observations, especially on spasm, we theorize that atherosclerotic coronary artery disease modulates and physically opposes obstruction during spasm. This phenomenon may explain the midventricular variant of TTC and the lower incidence of TTC in men. We continue to recommend and perform acetylcholine testing to reproduce TTC and to confirm our theory that coronary spasm is its initial pathophysiologic factor. An improved understanding of TTC is especially important because of the condition's markedly increased incidence during the ongoing COVID-19 pandemic.

Published: August 2021

Abstract

Objectives
Intervertebral disc segmentation is one of the methods to diagnose spinal disease through the degeneration in asymptomatic and symptomatic patients. Even though numerous intervertebral disc segmentation techniques are available, classifying the grades in the intervertebral disc is a hectic challenge in the existing disc segmentation methods. Thus, an effective Whale Spine-Generative Adversarial Network (WSpine-GAN) method is proposed to segment the intervertebral disc for effective grade classification.

Methods
The proposed WSpine-GAN method effectively performs the disc segmentation, wherein the weights of Spine-GAN are optimally tuned using Whale Optimization Algorithm (WOA). Then, the refined disc features, such as pixel-based features and the connectivity features are extracted. Finally, the K-Nearest Neighbor (KNN) classifier based on the pfirrmann’s grading system performs the grade classification.

Results
The implementation of the grade classification strategy based on the proposed WSpine-GAN and KNN is performed using the real-time database, and the performance based on the metrics yielded the accuracy, true positive rate (TPR), and false positive rate (FPR) values of 97.778, 97.83, and 0.586% for the training percentage and 92.382, 90.580, and 1.972% for the K-fold value.

Conclusions
The proposed WSpine-GAN method effectively performs the disc segmentation by integrating the Spine-GANmethod and WOA. Here, the spinal cord images are segmented using the proposed WSpine-GAN method by tuning the weights optimally to enhance the performance of the disc segmentation.

Published: August 2021

Zusammenfassung
Zahlreiche chinesische Unternehmen haben den Weg nach Deutschland gefunden und investieren nicht nur in neue Standorte, sondern auch in Fachpersonal. Eine kulturell diverse Belegschaft trifft auf eine vom Mutterkonzern entsandte chinesische Führungskraft, die selbst oft mit der fremden Umgebung hadert. Aus diesem Spannungsverhältnis ergeben sich verschiedene Herausforderungen. Der vorliegende Beitrag setzt sich zum Ziel, das Diversitätsmanagement in der Arbeitspraxis chinesischer Unternehmen in Deutschland in seiner interkulturellen Wirklichkeit zu erkunden. Durch leitfadengestützte Experteninterviews mit chinesischen und deutschen Fach- und Führungskräften konnten wichtige Aspekte und Spannungsfelder im Diversitätsmanagement von 42 befragten Unternehmen identifiziert werden. Basierend auf der Codierung und Analyse der Interviewdaten konnten Strategien und Erfolge im Diversitätsmanagement auf drei Ebenen konstatiert werden: Die grundlegende, die tragende und die äußere Ebene, welche in einem gegenseitigen Zusammenspiel eine vitale Einheit für die Nutzung von Vielfalt bilden, der Reziprozität, Eigendynamik und Prozesshaftigkeit innewohnen.
The microstructure of magnetorheological materials characterized by means of computed X-ray microtomography
Authors: Schümann Malte , Odenbach Stefan 
Published: August 2021

AbstractMagnetorheological materials are a class of “smart materials”, where mechanical material properties can be tuned by the application of externally applied fields. To accomplish the magneto-sensitive quality, magnetic particlesare distributed in a host matrix. In the last year’s interest gained in materials based on solid matrices. In contrast to fluid systems, within a solid matrix, the particles are fixed within the material. This enables an evaluation of the structures formed by the particles by means of computed X-ray microtomography. As known from past investigations, the arrangement and movement of the magnetic particles within the matrix play a major role in determining the overall material properties. Computed X-ray microtomography proved to be a convenient tool, providing important new knowledge about those materials. This paper gives an overview of the application of the method of computed X-ray microtomography on several kinds of solid magnetorheological materials, the broad possibilities of data evaluation, and fundamental results obtained with this method and the described materials.
The readability of online health information for L1 and L2 Australians: text-based and user-focused research
Authors: Peters Pam , Kruger Jan-Louis 
Published: August 2021

Abstract
The readability of online health information involves several factors in communication, including textual factors in verbal messaging and demographics relating to the readership, both of which impact on access to health information for first language (L1) and second language (L2) individuals in the Australian community. This research aims to identify the issues inherent in health texts as well as different readers’ comprehension of the information in them. The paper focuses first on the readability of sample health texts, and the extent to which difficult elements can be identified by the standard readability measures (Flesch-Kincaid, SMOG), as well as psycholinguistically informed measures of reading ease developed by Co-Matrix for general (L1) and L2 readers: TERA and Coh-Metrix L2. Coh-Metrix L2 points to linguistic factors that particularly challenge L2 readers of health information. A complementary study using eye-tracking was carried out to investigate the reading behaviours of 30 L1 and L2 participants seeking information from a health website. Statistically significant differences were found between L1 and L2 participants in their reading patterns, with L2 readers working more slowly and less reliably through online information. The findings highlight the need for health communicators to embrace the greater reading challenges for L2 users of the Internet.

OBJECTIVES
In this study, we aimed to characterize the clinical presentation, short-term prognosis, and myocardial tissue changes as noted on cardiovascular magnetic resonance (CMR) or cardiac MRI in pediatric patients with coronavirus disease 2019 vaccination-associated myocarditis (C-VAM).

METHODS
In this retrospective multicenter study across 16 US hospitals, patients &lt;21 years of age with a diagnosis of C-VAM were included and compared with a cohort with multisystem inflammatory syndrome in children. Younger children with C-VAM were compared with older adolescents.

RESULTS
Sixty-three patients with a mean age of 15.6 years were included; 92% were male. All had received a messenger RNA vaccine and, except for one, presented after the second dose. Four patients had significant dysrhythmia; 14% had mild left ventricular dysfunction on echocardiography, which resolved on discharge; 88% met the diagnostic CMR Lake Louise criteria for myocarditis. Myocardial injury as evidenced by late gadolinium enhancement on CMR was more prevalent in comparison with multisystem inflammatory syndrome in children. None of the patients required inotropic, mechanical, or circulatory support. There were no deaths. Follow-up data obtained in 86% of patients at a mean of 35 days revealed resolution of symptoms, arrhythmias, and ventricular dysfunction.

CONCLUSIONS
Clinical characteristics and early outcomes are similar between the different pediatric age groups in C-VAM. The hospital course is mild, with quick clinical recovery and excellent short-term outcomes. Myocardial injury and edema are noted on CMR. Close follow-up and further studies are needed to understand the long-term implications and mechanism of these myocardial tissue changes.

Authors: Chaves Jésura 
Published: August 2021

Este artigo baseia-se em uma pesquisa que culminou em uma tese de doutorado sobre a relação entre compreensão leitora, consciência textual e escritura argumentativa, pautando-se especialmente em postulados psicolinguísticos. Nesse sentido, buscou-se contribuir para o aprimoramento de práticas pedagógicas concernentes à leitura e à produção textual, considerando o importante papel que a consciência exerce nesse processo. A pesquisa objetivou, primeiramente, verificar a correlação entre as variáveis em pauta; num segundo momento, propor estratégias pedagógicas que possam potencializar a compreensão leitora e a escritura de textos argumentativos por intermédio da consciência textual. Nesse intuito, avaliou-se o desempenho de setenta e quatro alunos do primeiro, do segundo e do terceiro ano do ensino médio por meio de testes específicos. Procedeu-se, então, à análise de correlação entre duas variáveis separadamente, em cada ano escolar, pelo cálculo do coeficiente de correlação linear de Pearson (r). Os resultados da pesquisa confirmaram a correlação entre as variáveis avaliadas, que se estabeleceram sob diferentes índices. A partir da análise dos dados obtidos, que oferecem importantes indícios sobre o comportamento dos sujeitos, postulou-se sobre a necessidade de se estimular mais precocemente o raciocínio argumentativo nas escolas, com base em atividades de reflexão e de automonitoramento.
Labour productivity, wages and the functional distribution of income in Portugal: A sectoral approach
Authors: Lopes João Carlos , Coelho José Carlos , Escária Vítor 
Published: August 2021

Abstract
The main purpose of this paper is to study the functional distribution of income in Portugal in the long run, considering the period between 1953 and 2017. The labour share in income or value added depends on two fundamental variables, labour productivity and the average labour compensation. The trends of these variables are quantified for the aggregate economy and for its main productive sectors. An interesting result emerges, namely the different dynamics across sectors, both for the (unadjusted) wage share (considering only the wages of employees) and for the adjusted labour share (considering also as labour compensation one fraction of mixed income). Moreover, a shift-share analysis is used, in order to distinguish the importance of each sector's wage share evolution (“within” effect) and the changes in each sector's weight (structural changes, or “between” effect). Finally, a first attempt to incorporate the effect of wage inequality on the functional distribution of income is made, subtracting the labour compensation of the highest paid workers (top 10%, 5% and 1%) in order to calculate the wage share of the (so-called) "typical" workers.

Published: August 2021

Abstract: Marriage ratification or itsbat nikah is a way out for unregistered marriages in order to obtain registration and recognition from the state. Not every application for ratification of marriage is always granted, sometimes the application is rejected which refers to the Compilation of Islamic Law. This paper has the aim of revealing the basis for the judge's considerations as well as having a role as chairman of the Purwakarta Religious Court when processing several cases regarding the legalization of underage marriages which always grants and never rejects the application, this is interesting because there is a decision by another Religious Court judge who refuses similar application. This study uses this analysis method (content analysis) with a qualitative approach. The results of this study show that the judge in question concluded that the age of the bride and groom is not a benchmark for accepting or rejecting the application for itsbat marriage, but the parameter is that every marriage that meets the conditions and pillars is legal and worthy of marriage, but unfortunately the conclusion is not attached to the sheet. the decision and give the impression that it is very easy to apply for an istbat. Therefore, underage marriages as long as they fulfill the pillars and requirements are treated as legal marriages and will always be accepted and granted the application for ratification of marriage.Absktrak: Pengesahan nikah atau itsbat nikah merupakan jalan keluar bagi pernikahan yang tidak tercatat demi mendapatkan pencatatan dan pengakuan dari negara. Tidak setiap permohonan pengesahan nikah itu selalu dikabulkan, adakalanya permohonan itu ditolak yang mengacu pada Kompilasi Hukum Islam. Tulisan ini bertujuan untuk mengungkapkan dasar landasan pertimbangan hakim sekaligus memiliki peran sebagai ketua Pengadilan Agama Purwakarta ketika menangani beberpa perkara tentang pengesahan nikah perkawinan anak di bawah umur yang selalu mengabulkan dan tidak pernah menolak permohonan tersebut, hal ini menarik karena adaya putusan hakim Pengadilan Agama lain yang menolak permohonan yang serupa. Penelitian ini mengguna­kan metode analisis ini (content analysis) dengan pendekatan kualitatif. Hasil penelitian ini menunjukan bawa hakim yang bersangkutan memberikan kesimpulan bahwa usia pengantin bukanlah patokan untuk menerima atau menolak permohonan itsbat nikah, melainkan parameternya adalah setiap perkawinan yang terpeuhi syarat dan rukunya itu adalah sah dan layak untuk diistbatkan, namun sangat disayangkan ungkapan tersebut tidak dilampirkan dan dituliskan secara jelas dalam setiap lembaran putusan yang memerikan kesan bahwa hakim sangat mempermudah sekali untuk menga­bulkan istbat. Oleh karena itu pernikahan dibawah umur selama memenuhi rukun dan syarat dininai sebagai perkawinan yang san dan akan selalu diterima dan dikabulkan permohonan pengeshan nikahnya di Pengadilan Agama Purwakarta.

Influences of Cross-Sea High-Voltage Transmission Lines on Navigational Aids
Authors: Xueyuan Zhu Qinglong Hao, Jie Zhang, 
Published: August 2021

With the development of high-voltage electric power industry and the construction of cross-sea transmission projects in coastal ports, the interference of cross-sea high-voltage transmission lines on the performance of ship navigation aids gains considerable attention. The navigation safety control measures for ships crossing the waters of high-voltage transmission lines are proposed to study the navigational safety of the waters for the construction of high-voltage transmission lines across the sea. Conclusions with certain reliability are also drawn based on the analysis of the reasons and mechanisms of the interference phenomenon for the reference of maritime and scientific researchers. The images or signals of interference under the electromagnetic radiation from maritime shore-based radars, shipborne radars, shipborne VHF and GPS equipment through high-voltage transmission lines are obtained through on-site and actual ship testing.
