Self-forming dynamic membrane filtration for drinking water treatment
Authors: Celik Suna Ozden , Tufekci Nese , Koyuncu Ismail
Published: September 2021

Lab-scale continuous operation of self-forming microfiltration (MF) or ultrafiltration (UF) dynamic membranes were investigated simultaneously by applying iron oxide as an alternative treatment option in those waters having natural organic matter (NOM), iron and manganese. Both dynamic membranes gave high removal rates and effluent concentrations of pollutants were below the limit values in synthetic water. 60 and 62% (of DOC) and 75 and 78% (of UV254) were removed in low dissolved organic carbon (DOC) synthetic (LS) water by MF and UF dynamic membranes, respectively. Although only 42 and 49% (of DOC) and 48 and 53% (of UV254) could be removed by MF and UF dynamic membranes, respectively, a remarkable effect on fouling alleviation was observed in high DOC synthetic (HS) water. Iron oxide did not enhance the removal of organic matter in low DOC natural (LN) water as much as it did in synthetic water. Iron oxide led to the removal of high molecular weight organics, thus reversible fouling was reduced almost 2 orders of magnitude through both types of dynamic membranes in high DOC natural (HN) water. Reversible and irreversible resistances were reduced by iron oxide to some extent in LN water. Nevertheless the effect of iron oxide on fouling alleviation was much higher in HN rather than in LN water.

Published: September 2021

Ti-based electrode coated with MnOx catalytic layer has presented superior electrochemical activity for degradation of organic pollution in wastewater, however, the industrial application of Ti-based MnOx electrode is limited by the poor stability of the electrode. In this study, the novel Ti-based MnOx electrodes co-incorporated with rare earth (Ce) and conductive carbon black (C) were prepared by spraying-calcination method. The Ti/Ce:MnOx-C electrode, with uniform and integrated surface and enhanced Mn(IV) content by C and Ce co-incorporation, could completely remove ammonia nitrogen (NH4+-N) with N2 as the main product. The cell potential and energy consumption of Ti/Ce:MnOx-C electrode during the electrochemical process was significantly reduced compared with Ti/MnOx electrode, which mainly originated from the enhanced electrochemical activity and reduced charge transfer resistance by Ce and C co-incorporation. The accelerated lifetime tests in sulfuric acid showed that the actual service lifetime of Ti/Ce:MnOx-C was ca. 25 times that of Ti/MnOx, which demonstrated the significantly promoted stability of MnOx-based electrode by Ce and C co-incorporation.

Authors: Schulz dos Santos Paula , Cristina Barros da Silva Livia
Published: September 2021

Dado o papel chave que a Embratur – Agência Brasileira de Promoção Internacional do Turismo tem no turismo nacional, sendo o órgão mais antigo do tipo em atividade, o presente trabalho propôs-se a estudar, de maneira qualitativa e exploratória, a construção de políticas públicas desde sua criação até os dias atuais, analisando as estratégias de promoção do Brasil no exterior. Para isso, realizou-se a análise documental da legislação, planos, programas e ações do órgão de 1966 a 2019. Os resultados foram analisados a partir das perspectivas de pesquisa avaliativa e análise de conteúdo, apontando para questões-chave a serem abordadas a partir de sua mudança de natureza jurídica ocorrida em 2020. As questões-chave são: a marca país; o regime de contratações; o acesso à recursos financeiros e tecnologias para melhor aproveitar os bens turísticos nacionais; a compreensão de sua própria história, a fim de evitar cometer novamente os erros do passado, como a não observação às tendências mundiais em promoção, utilização de linguagem de promoção com conotação sexual (desde as revistas dos anos 70 até o slogan “Brazil, visit and love us” e a falta de política norteadora clara para execução de suas ações.

A Casa da rua São Francisco: um caso folkcomunicacional do turismo de assombrações em Diamantina – MG
Authors: Nascimento Alan , Sousa de Oliveira Jéssica
Published: September 2021

O Turismo de assombrações é um segmento do chamado turismo histórico-cultural. O processo de construção desse tipo de produto turístico suscita a questão de como é que os elementos próprios do mundo da tradição têm atraído as audiências modernas, turistas e viajantes. Na tentativa de oferecer uma resposta, este trabalho explora, conceitual e empiricamente, a turistificação de histórias de assombrações com base na noção de folkcomunicação. As técnicas de pesquisa adotadas pela investigação compreendem revisão bibliográfica e observação participante no city tour “Lendas do Tijuco”, realizado pela agência de turismo “Minhas Gerais”, na cidade de Diamantina-MG. Como resultado da investigação, sustenta-se que o turismo de assombrações se baseia num processo em que elementos da tradição local se mesclam com estéticas transnacionais, oriundas do cinema, da cultura pop do terror, das indústrias culturais, em geral, o que transforma almas penadas, a violência contra o escravo, a cultura funerária colonial, entre outras referências da morte de outrora, numa experiência turística, paradoxalmente, reconhecida e atual.

A Percepção da hospitalidade nas cidades do Porto, Portugal e Rio de Janeiro, Brasil
Authors: Valduga Manoela , Costa Carlos Manuel , Breda Zélia Maria
Published: September 2021

O presente artigo tem como objetivo identificar e analisar a percepção da hospitalidade por parte de turistas internacionais nas cidades do Porto, em Portugal, e do Rio de Janeiro, no Brasil. O tema da hospitalidade é tratado teoricamente dentro de duas perspectivas distintas e até certo ponto antagônicas. De acordo com a corrente francesa de estudos, ela é considerada, resumidamente, como uma prática social, enquanto para a corrente anglo-saxônica ela assume valor comercial. Com o intuito de não influenciar os turistas entrevistados quanto às diferentes abordagens teóricas, optou-se pela metodologia de estudos denominada grounded theory, originalmente desenvolvida no campo da sociologia para áreas temáticas de pouca abordagem teórica, mas aqui adaptada para o oposto, que é quando um termo, de tão empregado, acaba por ter o seu significado distorcido. Os resultados, a partir da análise de conteúdo das entrevistas, identificaram oito categorias a posteriori de análise da hospitalidade, quais sejam: características da população, características dos empregados de bares, restaurantes, hotéis e similares, referência ao idioma/comunicação, características da cidade, infraestrutura turística, cuidado com o turista, sensação de exploração ao turista/turismo e mobilidade. Observou-se que as impressões pertinentes às pessoas, sejam residentes ou prestadores de serviço, foram categorias espontâneas com maior incidência, reforçando, em paralelo, a prevalência da chamada corrente de estudos francesa sobre a corrente de estudos anglo-saxônica, de viés comercial.

Recurrent Artery of Heubner Aneurysm Masquerading as Caudate Hemorrhage without Subarachnoid Hemorrhage in Moyamoya Disease: A Case Report and Literature Review
Authors: Li Youxiang , Fu Chao , Jiang Peng , Zhao Yang
Published: September 2021

Background:

Clinically, the recurrent artery of the Heubner (RAH) aneurysm is extremely
rare, commonly presents with subarachnoid hemorrhage (SAH).

Case Report:

A 73-year-old man with a known moyamoya disease was presented as caudate hemorrhage
attributable to an incidental flow aneurysm distal on the right RAH, which was managed
conservatively after an unsuccessful endovascular attempt. Unfortunately, the patient died five
weeks after hospital discharge because of the re-rupture of the aneurysm. To the best of our knowledge,
the RAH aneurysm manifesting as caudate hemorrhage without SAH has not previously been
reported.

Conclusion:

This case highlights that the RAH aneurysm masquerading as caudate hemorrhage
without SAH is exceedingly rare but can be encountered, representing a diagnostic and therapeutic
challenge, and should be considered in the differential diagnosis. Moreover, early identifying and
then eliminating such vascular anomaly if possible is of importance to prevent fatal hemorrhage.
Computational Exploration of Functional Nanoscale Carbonaceous
Materials
Authors: Sereda Grigoriy , Uddin Md Tusar , Wente Jacob
Published: September 2021

Background:

The unique ability of carbon to form a wide variety of allotropic modifications
has ushered in a new era in material science. Tuning the properties of these materials by functionalization
is a must-have tool for their design customized for a specific practical use. The exponentially
growing computational power available to researchers allows for the prediction and thorough
understanding of the underlying physicochemical processes responsible for the practical properties
of pristine and modified carbons using the methods of quantum chemistry.

Method:

This review focuses on the computational assessment of the influence of functionalization
on the properties of carbons and enabling desired practical properties of the new materials. The first
section of each part of this review focuses on graphene with nearly planar units built from sp2-
carbons. The second section discusses patterns of sp2-carbons rolled up into curved 3D structures in a
variety of ways (fullerenes). The overview of other types of carbonaceous materials, including those
with a high abundance of sp3-carbons, including nanodiamonds, can be found in the third section of
each manuscript’s part.

Conclusion:

The computational methods are especially critical for predicting electronic properties of
materials such as the bandgap, conductivity, optical and photoelectronic properties, solubility, adsorptivity,
the potential for catalysis, sensing, imaging, and biomedical applications. We expect that
introduction of defects to carbonaceous materials as a type of their functionalization will be a point
of growth in this area of computational research.
Endovascular Therapies for Type B Aortic Dissection
Authors: Makhija Rakhee R. , Mukherjee Debabrata
Published: September 2021

:

Aortic dissection is a life-threatening condition resulting from a tear in the intimal layer of the aorta, requiring emergent diagnosis and prompt multi-disciplinary management strategy for best patient outcomes. While type A dissection involving ascending aorta is best managed surgically due to high early mortality, Type B Aortic Dissection (TBAD) involving descending aorta generally has better outcomes with conservative management and medical therapy as a primary strategy is favored. However, there has been a recent paradigm shift in the management of TBAD due to late aneurysmal degeneration of TBAD, increasing morbidity and mortality in the long term. Late surgical intervention can be prevented by early endovascular intervention when combined with optimal medical therapy. In this narrative review, we explore available literature on different endovascular therapies for TBAD in different populations of patients.

Social Media Sharing of Articles About Measles in a European Context: Text Analysis Study
Authors: Wawrzuta Dominik , Jaworski Mariusz , Gotlib Joanna , Panczyk Mariusz
Published: September 2021

Background

Despite the existence of an effective vaccine, measles still threatens the health and lives of many Europeans. Notably, during the COVID-19 pandemic, measles vaccine uptake declined; as a result, after the pandemic, European countries will have to increase vaccination rates to restore the extent of vaccination coverage among the population. Because information obtained from social media are one of the main causes of vaccine hesitancy, knowledge of the nature of information pertaining to measles that is shared on social media may help create educational campaigns.

Objective

In this study, we aim to define the characteristics of European news about measles shared on social media platforms (ie, Facebook, Twitter, and Pinterest) from 2017 to 2019.

Methods

We downloaded and translated (into English) 10,305 articles on measles published in European Union countries. Using latent Dirichlet allocation, we identified main topics and estimated the sentiments expressed in these articles. Furthermore, we used linear regression to determine factors related to the number of times a given article was shared on social media.

Results

We found that, in most European social media posts, measles is only discussed in the context of local European events. Articles containing educational information and describing world outbreaks appeared less frequently. The most common emotions identified from the study’s news data set were fear and trust. Yet, it was found that readers were more likely to share information on educational topics and the situation in Germany, Ukraine, Italy, and Samoa. A high amount of anger, joy, and sadness expressed within the text was also associated with a higher number of shares.

Conclusions

We identified which features of news articles were related to increased social media shares. We found that social media users prefer sharing educational news to sharing informational news. Appropriate emotional content can also increase the willingness of social media users to share an article. Effective media content that promotes measles vaccinations should contain educational or scientific information, as well as specific emotions (such as anger, joy, or sadness). Articles with this type of content may offer the best chance of disseminating vital messages to a broad social media audience.
Replicating Anatomical Teaching Specimens Using 3D Modeling Embedded Within a Multimodal e-Learning Course: Pre-Post Study Exploring the Impact on Medical Education During COVID-19
Authors: Stunden Chelsea , Zakani Sima , Martin Avery , Moodley Shreya , Jacob John
Published: September 2021

Background

The COVID-19 pandemic has had significant effects on anatomy education. During the pandemic, students have had no access to cadavers, which has been the principal method of learning anatomy. We created and tested a customized congenital heart disease e-learning course for medical students that contained interactive 3D models of anonymized pediatric congenital heart defects.

Objective

The aim of this study is to assess whether a multimodal e-learning course contributed to learning outcomes in a cohort of first-year undergraduate medical students studying congenital heart diseases. The secondary aim is to assess student attitudes and experiences associated with multimodal e-learning.

Methods

The pre-post study design involved 290 first-year undergraduate medical students. Recruitment was conducted by course instructors. Data were collected before and after using the course. The primary outcome was knowledge acquisition (test scores). The secondary outcomes included attitudes and experiences, time to complete the modules, and browser metadata.

Results

A total of 141 students were included in the final analysis. Students’ knowledge significantly improved by an average of 44.6% (63/141) when using the course (SD 1.7%; Z=−10.287; P<.001). Most students (108/122, 88.3%) were highly motivated to learn with the course, and most (114/122, 93.5%) reported positive experiences with the course. There was a strong correlation between attitudes and experiences, which was statistically significant (rs=0.687; P<.001; n=122). No relationships were found between the change in test scores and attitudes (P=.70) or experiences (P=.47). Students most frequently completed the e-learning course with Chrome (109/141, 77.3%) and on Apple macOS (86/141, 61%) or Windows 10 (52/141, 36.9%). Most students (117/141, 83%) had devices with high-definition screens. Most students (83/141, 58.9%) completed the course in <3 hours.

Conclusions

Multimodal e-learning could be a viable solution in improving learning outcomes and experiences for undergraduate medical students who do not have access to cadavers. Future research should focus on validating long-term learning outcomes.

Published: September 2021

Background

Personal health records (PHRs) are eHealth tools designed to support patient engagement, patient empowerment, and patient- and person-centered care. Endorsement of a PHR by health care providers (HCPs) facilitates patient acceptance. As health care organizations in the Kingdom of Saudi Arabia begin to adopt PHRs, understanding the perspectives of HCPs is important because it can influence patient adoption. However, no studies evaluated HCPs’ acceptance of PHRs in the Kingdom of Saudi Arabia.

Objective

The aim of this study was to identify predictors of HCPs’ acceptance of PHRs using behavioral intention to recommend as a proxy for adoption.

Methods

This cross-sectional study was conducted among HCPs (physicians, pharmacists, nurses, technicians, others) utilizing a survey based on the Unified Theory of Acceptance and Use of Technology. The main theory constructs of performance expectancy, effort expectancy, social influence, facilitating conditions, and positive attitude were considered independent variables. Behavioral intention was the dependent variable. Age, years of experience, and professional role were tested as moderators between the main theory constructs and behavioral intention using partial least squares structural equation modeling.

Results

Of the 291 participants, 246 were included in the final analysis. Behavioral intention to support PHR use among patients was significantly influenced by performance expectancy (β=.17, P=.03) and attitude (β=.61, P<.01). No moderating effects were present.

Conclusions

This study identified performance expectancy and attitude as predictors of HCPs’ behavioral intention to recommend PHR to patients. To encourage HCPs to endorse PHRs, health care organizations should involve HCPs in the implementation and provide training on the features available as well as expected benefits. Future studies should be conducted in other contexts and include other potential predictors.

The causes of the stenosis in patients were post-intubation (n=18) and post-tracheostomy for trauma (n=5). Most patients underwent extubation after 72 hours. The Myer-Cotton Grade of stenosis were grade 1 (n=1), grade 2 (n=13), and grade 3 (n=6). The major complications were dehiscence (n=3) and anastomotic edema (n=5). The minor complications were granulation (n=13) and mild anastomotic edema (n=1). One patient developed a surgical site infection and one patient developed a mild infection. The anastomotic fibrin deposition was developed in five patients. All patients had excellent satisfaction except for two patients (unsatisfactory). One of these patients died at month 1. The patients had normal medical conditions at different times of follow-ups.  
Conclusions: This study showed that the results of the patients with post-traumatic tracheal stenosis were acceptable at different times for most of them.

Published: September 2021

Objectives: In December 2019, SARS-CoV2 outbreak from China resulted in Covid-19 worldwide. The involvement of different organs, especially, heart disease can lead to hospitalization and enhance the rate of mortality and morbidity among severe patients. In a narrative review, we aimed to investigate the involvement of heart in adult and children with COVID-19 in critically ill patients.
Methods: The clinical and paraclinical manifestation of diseases in adults and children were searched in standard databases, such as PubMed, Google Scholar, Scopus, est. Also, the possible underlying mechanisms were investigated.
Results: The CVDs in COVID-19 patients has been characterized by several abnormalities such as myocarditis, acute myocardial injury, acute coronary syndrome, heart failure, arrhythmias, sudden cardiac arrest, coagulation abnormalities, thrombosis, and Kawasaki disease. The most probable mechanisms are attributed to SARS-CoV2 direct and indirect effects. The presence of angiotensin-converting enzyme 2 (ACE2) was confirmed in the cardiac tissue, confirming the direct attack of virus. Moreover, the cytokine storm as a result of enhanced levels of inflammatory mediators and infiltration of inflammatory cells into the cardiac disease, coagulation abnormalities, and endothelial dysfunction contribute to disease.
Conclusion: Cardiac diseases are seen in children and adults with COVID-19, related to the different mechanisms, mainly direct attack of virus and cytokine storm. Increasing the knowledge of cardiologists about the cardiac manifestations of COVID-9 in children and adults and underlying mechanisms can improve the consequences and reduce the mortality and morbidity rate among hospitalized patients.
Writing Rounds: An Innovation to Increase Physician Scientific Dissemination
Authors: Winnie Kirsten , Jackson Jeremy T. , Ledford Christy J.W.
Published: September 2021

Introduction: Many high-quality studies presented at conferences never reach the peer-reviewed literature, most likely because physician authors do not take the next step to fully write up the studies and submit them to a journal. We evaluated a curriculum designed to equip authors with the practical skills to submit research projects to peer-reviewed publication.
Methods: We designed a mixed asynchronous-synchronous longitudinal curriculum, occurring across 4 months via a virtual platform. To evaluate the curriculum, we tracked process and production outcomes and conducted semistructured interviews with participants following participation.
Results: Across two cohorts in 2019, nine participant authors completed the curriculum. Seven participants submitted their studies for publication; two were accepted. In interviews with eight participants, participant authors described the value of the program, expressing intention to participate again and to recommend it to colleagues.
Conclusion: Through a coach-directed writing group, participant authors developed the skills and confidence needed to prepare and submit scientific manuscripts for peer review. Curriculum maintenance and enhancement is ongoing. We plan to scale up this innovation in support of other university departments and medical disciplines, developing an implementation guide to describe needed elements, including technological platforms, qualities of the coach, author recruitment, and group conduct.
Microhabitat use, daily activity pattern and diet of Liolaemus etheridgei Laurent, 1998 (Reptilia: Liolaemidae) in the Andean Polylepis forests of Arequipa, Peru
Authors: Llanqui Irbin , Edwards Bryn , Lopez Evaristo
Published: September 2021

This study compared the microhabitat use, daily activity pattern and
diet of Liolaemus etheridgei Laurent 1998 in two Polylepis
woodlands: El Simbral (fragmented) and Tuctumpaya (unfragmented), in
Arequipa, Southern Peru. In both populations, we did not detect positive
selection for any microhabitat; however, the population at El Simbral
showed a negative selection for Polylepys trees while the Tuctumpaya
population showed negative selection for Polylepis trees and non-thorny
bushes. In El Simbral, active individuals were detected between 9:00 and
15:59h, whereas in Tuctumpaya, we detected active individuals from 8:00
to 17:59h. In both populations, observations of active individuals
dropped between 11:00 and 11:59h. We recorded 17 and 23 prey categories
in the El Simbral and Tuctumpaya populations respectively. The most
important animal prey category in each population was found to be
Lygaeidae: Hemiptera, and was the only animal prey category that was
selected for in El Simbral and Tuctumpaya. In addition, due to the
proportions of plant material found, the El Simbral was found to be
omnivorous, whereas the Tuctumpaya population was herbivorous. Trophic
niche breadth was broader in Tuctumpaya (B_a= 0.202) than the El
Simbral (B_a= 0.147) population, despite there being no significant
differences in diet (Permanova: F = 1.036, P = 0.409, permutations =
9999), which is coherent with the high value of trophic niche overlap
(O_(j,k) = 0.963). Our compiled data reveal that L. etheridgei
shows no selection for any of the resources we define in Polylepis
woodlands, on the contrary, it selects negatively against
Polylepis trees and non-thorny bushes. The daily activity
patterns indicate a bimodal pattern with peaks at 9:00-10:59 and
13:00-13:59 h. The diet of L. etheridgei consists mainly of
plants (%W: 66.373), and the most important animal prey category is
Lygaeidae: Hemiptera (%IRI = 55.3), which is selected positively.
Novel mitochondrial gene rearrangements pattern in the millipede Polydesmus sp. GZCS-2019 and phylogenetic analysis of the Myriapoda
Authors: Zuo Qing , Zhang Zhisheng , Shen Yanjun
Published: September 2021

The subphylum Myriapoda included four extant classes (Chilopoda,
Symphyla, Diplopoda and Pauropoda), but very little work has been done
to explore their phylogenetic relationships. Herein, we determined the
complete mitochondrial genome of Polydesmus sp. GZCS-2019 (Myriapoda:
Polydesmida) and the mitochondrial genomes are circular molecules of
15,036 bp, with all genes encoded on + strand. The A+T content is
66.1%, making the chain asymmetric, and exhibits negative AT-skew
(-0.236). Several genes rearrangements were detected and we propose a
new rearrangement model: “TD (N\R) L + C” based on the
genome-scale duplication + (non-random/random) loss + recombination.
Phylogenetic analyses demonstrated that Chilopoda and Symphyla both were
monophyletic group, whereas Pauropoda was embedded in Diplopoda to form
the Dignatha. Divergence time showed the first split of Myriapoda
occurred between the Chilopoda and other classes (Wenlock period of
Silurian). We combine phylogenetic analysis, divergence time, and gene
arrangement to yield valuable insights into the evolutionary history and
classification relationship of Myriapoda and these results support a
monophyletic Progoneata and the relationship (Chilopoda + (Symphyla +
(Diplopoda + Pauropoda))) within Myriapod. Our results help to better
explain the gene rearrangement events of the invertebrate mitogenome and
lay the foundation for further phylogenetic study of Myriapoda.

This study investigated the association of diabetes in patients who recovered from severe acute respiratory syndrome coronavirus 2 infection with the presence of long-term post–coronavirus disease (COVID) symptoms. A case-control study that included individuals hospitalized during the first wave of the pandemic was conducted. Patients with a previous diagnosis of diabetes and under medical control were considered case subjects. Two age- and sex-matched patients without presenting diabetes per case subject were recruited as control subjects. Hospitalization and clinical data were collected from hospital medical records. Patients were scheduled for a telephone interview. A list of post-COVID symptoms was systematically evaluated, but participants were invited to freely report any symptom. The Hospital Anxiety and Depression Scale and the Pittsburgh Sleep Quality Index were used to assess anxiety and depressive symptoms, and sleep quality, respectively. Multivariable conditional logistic regression models were constructed. Overall, 145 patients with diabetes and 144 control subjects without diabetes who had recovered from COVID-19 were assessed at 7.2 (SD 0.6) months after hospital discharge. The number of post-COVID symptoms was similar between groups (incident rate ratio 1.06, 95% CI 0.92–1.24, P = 0.372). The most prevalent post-COVID symptoms were fatigue, dyspnea on exertion, and pain. No between-groups differences in any post-COVID symptom were observed. Similarly, no differences in limitations with daily living activities were found between patients with and without diabetes. Diabetes was not a risk factor for experiencing long-term post-COVID symptoms.

Authors: DONUK Kenan , ARI Ali , ÖZDEMİR Mehmet Fatih , HANBAY Davut
Published: September 2021

Facial expressions, which are important social communication tools in our daily life, provide important information about the mental state of people. Research is being done to obtain this information accurately. The importance of these researchs in the field of human-computer interaction is increasing. Many methods have been used for the recognition of universal facial expressions such as neutral, happiness, surprise, sadness, anger, disgust, and fear by intelligent systems with high accuracy. Emotion recognition is an example of difficult classification due to factors such as ambient light, age, race, gender, and facial position. In this article, a 3-stage system is proposed for emotion detection from facial images. In the first stage, the CNN-based network is trained with the Fer+ dataset. The Binary Particle Swarm Optimization algorithm is applied for feature selection to the feature vector in the fully connected layer of the CNN network trained in the second stage. Selected features are classified by Support Vector Machine. The performance of the proposed system has been tested with the Fer+ dataset. As a result of the test, 85.74% accuracy was measured. The results show that the combination of BPSO and SVM contributes to the classification accuracy and speed of the FER+ dataset.
