Modeling Predictive Age-Dependent and Age-Independent Symptoms and Comorbidities of Patients Seeking Treatment for COVID-19: Model Development and Validation Study
Authors: Huang Yingxiang , Radenkovic Dina , Perez Kevin , Nadeau Kari , Verdin Eric , Furman David
Published: February 2021

Background

The COVID-19 pandemic continues to ravage and burden hospitals around the world. The epidemic started in Wuhan, China, and was subsequently recognized by the World Health Organization as an international public health emergency and declared a pandemic in March 2020. Since then, the disruptions caused by the COVID-19 pandemic have had an unparalleled effect on all aspects of life.

Objective

With increasing total hospitalization and intensive care unit admissions, a better understanding of features related to patients with COVID-19 could help health care workers stratify patients based on the risk of developing a more severe case of COVID-19. Using predictive models, we strive to select the features that are most associated with more severe cases of COVID-19.

Methods

Over 3 million participants reported their potential symptoms of COVID-19, along with their comorbidities and demographic information, on a smartphone-based app. Using data from the >10,000 individuals who indicated that they had tested positive for COVID-19 in the United Kingdom, we leveraged the Elastic Net regularized binary classifier to derive the predictors that are most correlated with users having a severe enough case of COVID-19 to seek treatment in a hospital setting. We then analyzed such features in relation to age and other demographics and their longitudinal trend.

Results

The most predictive features found include fever, use of immunosuppressant medication, use of a mobility aid, shortness of breath, and severe fatigue. Such features are age-related, and some are disproportionally high in minority populations.

Conclusions

Predictors selected from the predictive models can be used to stratify patients into groups based on how much medical attention they are expected to require. This could help health care workers devote valuable resources to prevent the escalation of the disease in vulnerable populations.

Authors: Kataoka Yuki , Takemura Tomoyasu , Sasajima Munehiko , Katoh Naoki
Published: February 2021

Background

Chatbots are artificial intelligence–driven programs that interact with people. The applications of this technology include the collection and delivery of information, generation of and responding to inquiries, collection of end user feedback, and the delivery of personalized health and medical information to patients through cellphone- and web-based platforms. However, no chatbots have been developed for patients with lung cancer and their caregivers.

Objective

This study aimed to develop and evaluate the early feasibility of a chatbot designed to improve the knowledge of symptom management among patients with lung cancer in Japan and their caregivers.

Methods

We conducted a sequential mixed methods study that included a web-based anonymized questionnaire survey administered to physicians and paramedics from June to July 2019 (phase 1). Two physicians conducted a content analysis of the questionnaire to curate frequently asked questions (FAQs; phase 2). Based on these FAQs, we developed and integrated a chatbot into a social network service (phase 3). The physicians and paramedics involved in phase I then tested this chatbot (α test; phase 4). Thereafter, patients with lung cancer and their caregivers tested this chatbot (β test; phase 5).

Results

We obtained 246 questions from 15 health care providers in phase 1. We curated 91 FAQs and their corresponding responses in phase 2. In total, 11 patients and 1 caregiver participated in the β test in phase 5. The participants were asked 60 questions, 8 (13%) of which did not match the appropriate categories. After the β test, 7 (64%) participants responded to the postexperimental questionnaire. The mean satisfaction score was 2.7 (SD 0.5) points out of 5.

Conclusions

Medical staff providing care to patients with lung cancer can use the categories specified in this chatbot to educate patients on how they can manage their symptoms. Further studies are required to improve chatbots in terms of interaction with patients.

Published: February 2021

Este artigo tem como objetivo reconhecer as ações de extensão desenvolvidas na Universidade Federal do Cariri, Ceará, que apresentam características de extensão popular.  Para tanto, realizamos uma pesquisa documental, utilizando como fonte o catálogo de ações de extensão dessa instituição, das ações desenvolvidas no ano de 2019 e na área de educação. Fundamentamos a nossa discussão na perspectiva teórica de Freire (1985, 2000, 2013), Melo Neto (1994, 2001, 2002), Arroyo (2012), Charlot (2013), Santos (2020), dentre outros. Baseamo-nos, também, na legislação, especificamente a Constituição Federal de 1988, no Plano Nacional de Educação e na Lei de Diretrizes e Bases da Educação Nacional n.º 9.394/96. Além da análise documental, realizamos uma pesquisa por meio de um questionário, via Google Forms. No que concerne aos programas e projetos desenvolvidos na UFCA, em educação, no ano de 2019, percebemos que todas as temáticas produzem conhecimentos e contribuem, de certo modo, para aquele público-alvo a que se destinam. Os resultados nos mostram que muitas das ações de extensão dessa instituição remetem às características da extensão popular e aos princípios maiores da universidade, que são inclusão e sustentabilidade. Não obstante, as Instituições de Ensino Superior ainda precisam trilhar um longo caminho, desenvolver a escuta do outro, construir junto com a comunidade para contribuir de modo mais efetivo para a solução de problemas concretos dos sujeitos que vivem nesses contextos.

Authors: Raidalva Nery Barreto Maria , Aquino Ribeiro Luciana , Roberto Tavares Sampaio José
Published: February 2021

Pormenorizar os processos de aquisição do conhecimento é um desafio para pesquisadores das distintas áreas. Considerando a aprendizagem um fenômeno que comporta a amplitude social e cultural dos indivíduos, as vivências no decorrer da história pessoal podem firmar um conjunto conceitual que permite aquisição e retenção de conhecimento. Este artigo tem como objetivo avaliar a representatividade da identidade culturalmente negra como ideia-âncora que contribui para a retenção de conhecimentos de alunos da graduação oriundos da periferia de Salvador. A pesquisa de natureza exploratória e empírica está fundamentada sob a perspectiva da aprendizagem significativa, proposta por David Ausubel (2001). Utiliza como amostra alunos da graduação em Comunicação Social da UNIFTC Campus Paralela, no período de agosto a dezembro de 2018, a partir do projeto gráfico elaborado para uma revista impressa. Legitimar o processo de afirmação da identidade étnico racial durante a experiência acadêmica potencializa a aprendizagem sendo possível contribuir com uma sociedade multicultural.

Authors: Silva Ribeiro Carolina , Maximiano Pereira Roberto , Garcia de Oliveira Gilca
Published: February 2021

O objetivo deste estudo é analisar a estrutura produtiva do semiárido baiano em 2015 e contribuir para a elaboração de políticas públicas que fomentem o seu desenvolvimento.  Para tanto, utiliza-se o ferramental insumo-produto para construir a matriz insumo-produto do semiárido baiano, com base na Matriz Bahia 2015. Faz-se um estudo exploratório dos setores de atividades econômicas da região, mediante a utilização de indicadores de insumo-produto como índices de ligações intersetoriais de Rasmussen-Hirschman, setor-chave, campo de influência e multiplicadores econômicos de produção, emprego e renda.  A análise mostrou que sete setores são de grande importância para a região – outros da indústria extrativa; alimentos, bebidas e fumo; têxtil, vestuário e artigos de couros; produtos químicos diversos; indústria da borracha e do plástico; metalurgia e siderurgia; eletricidade, gás, água, esgoto e limpeza urbana –, atuando como demandantes de insumos e ofertantes de produtos. Os multiplicadores econômicos mostraram que o setor de álcool e biocombustíveis é o que mais se destaca na produção. Já a administração pública, saúde e educação pública e seguridade social têm maior potencial para gerar empregos formais na economia.  Em relação à geração de renda, o setor agrícola tem um peso na região, destacando-se o cultivo de cereais e outras lavouras temporárias. Assim, ao avaliar a estrutura produtiva do semiárido baiano, espera-se contribuir com os agentes envolvidos na tomada de decisão para a elaboração de políticas visando o seu desenvolvimento social e econômico.

FORMADOR DE ADULTOS: O POTENCIAL (TRANS)FORMADOR DA BIOGRAFIA
Authors: Cavaco Carmen
Published: February 2021

O texto tem como objetivo analisar o potencial formativo da narrativa autobiográfica no formador de adultos. A análise resultou de uma investigação-formação-ação, filiada na hermenêutica, realizada com formadores de adultos, na condição de estudantes de mestrado, em Portugal. A investigação enquadrada no campo científico das Ciências da Educação baseou-se em dois pressupostos teóricos estruturantes: primeiro, considera-se que a educação e a formação são processos amplos e difusos, que ocorrem em todas as idades e contextos de vida e promovem uma transformação silenciosa; segundo, reconhece-se a importância de os formadores de adultos compreenderem o seu próprio processo de formação, como forma de potenciar o poder de ação e de transformação. Os formadores de adultos elaboraram uma biografia educativa centrada no percurso profissional e no processo de formação. A elaboração da narrativa biográfica mobilizou o sujeito num processo de reflexão, de rememoração, de seleção, de análise e de (re)elaboração da sua experiência, em dinâmicas de alternância entre o individual e o coletivo, a oralidade e a escrita. A análise destas narrativas biográficas permitiu compreender o poder formativo e transformador gerado pela reflexão, pela escrita de si e pela socialização da experiência. Os formadores de adultos atribuíram sentido e apropriam-se da sua experiência profissional e do seu processo de formação, o que desencadeou a autoformação. Nesse sentido, a biografia educativa apresentou um potencial transformador capaz de restituir o poder de ação e de formação dos formadores de adultos.
HISTÓRIAS DE VIDA E FORMAÇÃO DE CUIDADORAS DE IDOSOS
Authors: Araújo Mónica , Sarmento Teresa
Published: February 2021

Este artigo tem como objetivo refletir sobre histórias de vida de cuidadoras de idosos, enquanto método de investigação em si mesmo e como modalidade (auto)formativa em contexto profissional. Num processo de construção de histórias de vida partilhamos do rememorar de pedaços de vida individuais, que se tornam formativamente significativos para narradores, bem como para o investigador que assim pode questionar modalidades novas de concretização epistemológica. O artigo baseia-se num processo investigativo com cuidadoras de pessoas da terceira idade. O escutar as suas vozes constitui, à partida, o reconhecimento pelo valor da sua vida, o que releva a pertinência política das histórias de vida no campo pessoal, bem como da investigação enquanto manifestação do entendimento de cada sujeito como participante no processo de construção de conhecimento social. A produção oral, realizada durante a entrevista dos atores sociais que se narram, permite uma entrega do sujeito à sua própria história, enaltecendo aquela que é a sua identidade e transmitindo-a, aos poucos, ao investigador. A vida individual é uma expressão criadora que, quando tornada conhecida aos ouvidos e análise do investigador, tende a criar interpretações polissémicas e questionamentos, potenciando novas possibilidades formativas e epistemológicas. Os resultados do estudo mostraram que as histórias de vida serviram três importantes dimensões: 1) a auto consciencialização e autoformação das participantes, 2) o nosso acesso, enquanto formadoras-investigadoras, ao conhecimento das mesmas e 3) o valor epistémico das histórias de vida no campo de conhecimento de profissionais do humano.
ARMAZÉM DE MOMENTOS: UM MEMORIAL COLETIVO ELABORADO POR PROFESSORAS EM FORMAÇÃO
Authors: Furlanetto Ecleide Cunico , Sellani Helena Aparecida Verderamis , Biasoli Karina Alves
Published: February 2021

Este texto foca-se na análise de um memorial coletivo de formação denominado Armazém de Momentos, elaborado por sete professoras das séries iniciais do Ensino Fundamental. O objetivo do estudo foi investigar o modo como o trabalho com narrativas, em contexto formativo, poderia potencializar e revelar movimentos individuais e coletivos de formação. Foram estabelecidos diálogos teóricos com autores que investigam a pesquisa-ação-formação centrada nas narrativas, sobretudo, em histórias de vida, com o apoio do uso de memoriais, bem como com autores que abordam o conceito de símbolo e processo de individuação e processo de grupação, na perspectiva da Psicologia Analítica. A análise das narrativas que compõem o Armazém de Momentos evidenciou que a elaboração de um memorial escrito coletivamente, por professores, desencadeou percursos singulares e coletivos de formação, com pontos de aproximação e também de tensões, mediados pelo uso da linguagem e pela seleção de símbolos que foram construídos ao longo do percurso.

Authors: Souza Ester Maria de Figueiredo , Ferreira Lúcia Gracia
Published: February 2021

Este texto aborda o direto à matrícula escolar com a escolaridade nos tempos de pandemia do novo coronavírus. Parte do princípio de que a matrícula escolar é lastreada pelo direito à educação, conforme se preconiza na Constituição da República Federativa do Brasil (1988), simbolizando a validação da identidade estudantil. Para tanto, referencia-se nas normativas e leis que regem o ordenamento jurídico brasileiro para cotejar informações de domínio público e apresentam-se o ensino emergencial e mapeamento da situação de oferta da educação no país, expondo estratégias para validar o ano letivo, como também alternativas para terminalidade de estudos. Desse modo, se configurou como uma pesquisa qualitativa, exploratória e documental que reúne conjunto de dados relevantes para contexto e problematizacão do percurso do estudante. Constata-se que a pandemia atingiu o direito a matrícula, em maior escala nos estabelecimentos públicos de ensino e que foi protelada, por circunstâncias impostas pela COVID-19, a tomada de decisão para validar esse direito.

Authors: Sarwani Sarwani , Husain T.
Published: February 2021

Individuals and organizations cannot avoid the era of the Fourth Industrial Revolution (Industry 4.0) in any part of the world by utilizing the latest technological bases. These transformations will change the way humans live and interact in the future. Enterprise decisions are taken and become the most important from the firm’s value empirical models. This study aims to establish the implications of an empirical model of a firm’s value through some determinant factors, i.e., financial ratios with profitability and leverage, intellectual capital with human capital employment, the dividend policy, and audit quality with Big 4 category proxy. The research uses a causal-comparative type with a quantitative approach. Eleven final samples of automotive and components subsectors enterprises of the listed shares in Indonesian Stock Exchange (IDX) were appointed, from 2013 till 2019 by purposive sampling technique. Multiple regression was applied to analyze data on the proposed equation models. The findings state that the profitability and audit quality has positive significance, but leverage, intellectual capital, and dividend policy insignificant implications for predicting the firm’s value empirical model.
Egy letűnt műfaj? A fantasy izometrikus szerepjátékok eltűnésének lehetséges okai a 2000-es évek elején
Authors: Krek Norbert
Published: February 2021

A dolgozat az ezredforduló környékén megjelent mainstream izometrikus szerepjátékokat vizsgálja. A kutatás kiindulópontja az a megfigyelés, miszerint a 2010-es évtized végére a fantasy témájú, izometrikus szerepjáték alműfaja a szerepjátékok és az indie játékfejlesztés egyfajta reneszánszát elhozó Kickstarter – mint alternatív finanszírozási forma–, illetve más mediális folyamatok hatására képes volt részlegesen visszanyerni az ezredfordulón létező mainstream státuszát. Ennek tükrében válik izgalmas kérdéssé, hogy eleve mi okozta ennek az alműfajnak az eltűnését az ezredfordulón. A tanulmány egyrészt ez utóbbira keresi a választ, másrészt amellett érvel, hogy e műfajtörténeti folyamat nem értelmezhető egyszerű törésként, eltűnésként, inkább különböző videojáték-ipari folyamatok (mint például a cinematizáció) hatására bekövetkező műfaji átlényegülésként.
A COMPARATIVE EVALUATION OF COMPRESSIVE STRENGTH OF POSTERIOR RESTORATIVE MATERIALS: AN IN VITRO STUDY
Authors: Kaur Gurmeen , Shetty Chitharanjan , Shetty Aditya , HEGDE MITHRA
Published: February 2021

BACKGROUND AND OBJECTIVES: The ‘Basic filling materials’ Amalgam and
glass ionomer have been well accepted for posterior restorations, but
have multifarious drawbacks such as low flexural strength, surface wear,
porosity of glass ionomer cements, intrinsic grey unaesthetic appearance
of amalgam, its inability to bond tooth and concerns about mercury
content. Hence, newer materials were introduced in the market with
better biomechanical properties. The present study aimed to evaluate and
compare the compressive strength of Ceramic-Reinforced Glass Ionomer
cement, Zirconia-Reinforced Glass Ionomer cement, High Strength Glass
Ionomer Posterior restorative material, Alkasite restorative material,
and Amalgam when used as posterior restorative materials. METHODOLOGY:
Fifty cylindrical specimens measuring 6mm in height and 4mm in diameter
were fabricated using test materials. Class II cavity was prepared on
fifty intact permanent human molar teeth and randomly divided into five
groups based on the material to be filled with ten specimens each: Group
1- Ceramic-Reinforced Glass Ionomer cement, group 2- Zirconia-Reinforced
Glass Ionomer cement group 3- High Strength Glass Ionomer Posterior
restorative material group 4- Alkasite restorative material and group 5-
amalgam. All the specimens were thermocycled and stored in artificial
saliva for 24 hours. The specimens were subjected to compressive
strength testing using Universal Testing Machine (Zwick Roell, Z020,
Zwick, Ulm, Germany). Data were analyzed statistically using IMB SPSS
Statistics, Version 22 (Armonk, NY: IBM Corp). RESULTS: The present
study reveals a significantly high compressive strength of cylindrical
specimens of Group 4, followed by Group 5, Group 3, Group 1, and least
by Group 2. The highest maximum compressive load was supported by teeth
restored with the material of Group 4, Group 1, Group 5, Group 2, and
least by Group 3. CONCLUSION: Within the limitations of the study,
alkasite restorative material showed the highest compressive strength in
cylindrical and tooth specimens.

goals: examining ‘Papworth, Will-Bleed, Track and Trust’ bleeding
scoring systems to determine the most predictive one among diabetic
patients undergoing isolated coronary bypass surgery, and determining
the variables that should be included in the new scoring systems to be
established for this patient group. Methods: The files of 297 diabetic
patients who underwent isolated coronary artery bypass operation between
2017-2019 were retrospectively reviewed. Patients who underwent
emergency surgery with a beating heart, those with reoperated open hart
surgery, those with ticagrelor use, and those who died within the first
24 postoperative hours were excluded from the study. Drainage from the
thorax and mediastinal tubes and blood product transfusions to the
patients within the first 24 hours were noted and analyzed according to
scoring systems. Results: Scoring systems are evaluated based on
‘European Multicenter Study on Coronary Artery Bypass Grafting Bleeding
Severity (E-CABG)’. In this study including diabetic patients only,
Papworth was better predictive of E-CABG bleeding Grade 2-3. We found
that Will-Bleed, Track, Trust, the other scoring systems we examined had
discriminatory value in terms of E-CABG bleeding Grade 2-3 in our study
group. Among the parameters in the scoring systems, we concluded that
gender, preoperative hemoglobin (or hematocrit) value, preoperative
platelet count, use of antiplatelets until less than five days prior to
the operation, and preoperative creatinine (or eGFR) values should be
included in the scoring system we aim to establish in the future, called
the “Optimum Risk Score for Bleeding (ORS).” Conclusion: Considering
the possible risks of bleeding and blood product transfusion, scoring
systems that will provide accurate results for patient blood management
will be lifesaving and increase the cost-effectiveness of the treatment.
The design and optimization of novel elliptic cylindrical TSV and its temperature characterization
Authors: Guan Wenbo , Lu Hongliang , Zhang Yuming
Published: February 2021

Through Silicon Via (TSV) technology is a key technology to realize
multi-layer chips and its structure model and transmission
characteristics have attracted much attention. With the continuous
reduction of chip size, higher requirements are put forward for the
model and transmission characteristics of TSV. A novel elliptic
cylindrical TSV structure model is proposed. The influence of axial
length ratio, height, dielectric layer thickness and spacing on the
transmission characteristics of TSV are further studied by HFSS
software. The results show that the transmission of TSV is facilitated
by the decrease of axial length ratio, the decrease of height, the
increase of dielectric layer thickness and the increase of TSV spacing.
The TSV structural parameter values are optimized by a single variable
method. The optimized TSV structure is compared with the original TSV,
traditional cylindrical and conical TSV and coaxial TSV. It is concluded
that the elliptic cylindrical TSV structure has better transmission
performance. The temperature characteristics of the elliptic cylindrical
TSV are simulated. It is indicated that the transmission characteristics
of the elliptic cylindrical TSV are poor at low frequency and better at
high frequency when the temperature rises.
Aortic Aneurysm Disease - Make Room for Chronobiology
Authors: Lopuszko Aleksandra , Tan Cian , Munir Wahaj , Bashir Mohamad
Published: February 2021

Background Aortic Aneurysm (AA) is a common atherosclerotic condition,
accounting for nearly 6,000 deaths in England and up to 175,000 deaths
globally each year. The pathological outward bulging of the aorta
typically results from atherosclerosis or hereditary connective tissue
disorders. AAs are usually asymptomatic until spontaneous rupture or
detected on incidental screening. 8 in 10 patients do not survive the
rupture and die either before reaching hospital or from complications
following surgery. Similar to other cardiovascular pathologies (CVPs),
AA is thought to be subject to chronobiological patterns of varying
incidence. Methods We performed a literature review of the current
literature to evaluate the association between circadian rhythms,
seasonal variations, and genetic factors and the pathogenesis of AA,
reviewing the impact of chronobiology. Results The incidence of AA is
found to peak in the early morning (6 AM – 11 AM) and colder months,
and conversely troughs towards the evening and warmer months, exhibiting
a similar pattern of chronobiological rhythm as other CVPs such as
myocardial infarcts, or cerebrovascular strokes. Conclusion Literature
suggests there exists a clear relationship between chronobiology and the
incidence and pathogenesis of ruptured AA; incidence increases in the
morning (6am - 11am), and during colder months (December – January).
This is more pronounced in patients with Marfan Syndrome, or vitamin D
deficiency. The underlying pathophysiology and implications this has for
chronotherapeutics, are also discussed. Our review shows a clear need
for further research into the chronotherapeutic approach to preventing
ruptured AA in the journey towards precision medicine.

Objective : To analyze the application value of fast-track anesthesia in
percutaneous occlusion of patent foramen ovale under transesophageal
echocardiography. Methodology: 60 cases of patients with patent foramen
ovale were randomized into two groups to receive either fast-track
anesthesia(Group R) or conventional anesthesia(Group S).Record MAP and
HR before anesthesia (T0), tracheal intubation (T1), start of surgery
(T2), end of surgery (T3), exit anesthesia recovery room (PACU) (T4), as
well as the operation time, anesthesia time , Recovery time of
extubation, PACU stay time, recovery period agitation score, pain score
VAS out of the anesthesia recovery room (PACU), incidence of adverse
reactions. Results: There was no statistically significant difference in
the anesthesia time and operation time between the two groups, MAP and
HR before and after anesthesia between the two groups were not
statistically significant different. There was statistically significant
difference in recovery of spontaneous breathing, extubation time, PACU
stay time, postoperative restlessness score,and incidence of adverse
reactions. Conclusion: Fast-track anesthesia in percutaneous
transcatheter closure of patent foramen ovale under transesophageal
echocardiography can provide faster recovery of spontaneous breathing,
earlier extubation time, shorter PACU stay time, lower postoperative
restlessness score, lower incidence of adverse reactions.
The Innovation-Remuneration Index (IRI). Making pharmaceutical companies report what matters about innovation.
Authors: Cohen Adam , Ultee Rebecca , Veldhoven Glenn
Published: February 2021

There is a lack of transparency about the cost of innovation of the
pharmaceutical industry even though these costs are claimed to be the
major driver for high prices for medicines. This is reflected by annual
reports of the major pharmaceutical firms that contain a low number of
pages on innovation and its detailed costs, in comparison to pages about
remuneration of executives where the detail is excessive. The
Innovation/Remuneration Index (IRI) provides an objective view of the
transparency priorities of a company and has the potential to shift this
focus in favour of transparent and detailed information on the cost of
innovation.
Health effects of exposure to chlorination by-products in swimming pools: Position Paper
Authors: Couto Mariana , Bernard Alfred , Delgado Luís , Drobnic Franchek , Kurowski Marcin , Moreira André , Rodrigues-Alves Rodrigo , Rukhadze Maia , Seys Sven , Wiszniewska Marta , Quirce Santiago
Published: February 2021

Concerns have been raised regarding the potential negative effects on
human health of water disinfectants used in swimming-pools. Among the
disinfection options, the approaches using chlorine-based products have
been typically preferred. Chlorine readily reacts with natural organic
matter that are introduced in the water mainly through the bathers,
leading to the formation of potentially harmful chlorination by-products
(CBPs). The formation of CBPs is of particular concern since they have
been epidemiologically associated with the development of various
clinical manifestations. The higher the concentration of these volatile
CBPs in the water, the higher their concentration in the air above the
pool, and different routes of exposure to chemicals in swimming-pools
(water ingestion, skin absorption and inhalation) contribute to the
individual exposome. CBPs may affect the respiratory and skin health of
those who stay indoor for long periods, such as swimming instructors,
pool staff, and competitive swimmers. Whether those who use
chlorinated-pools as customers, particularly children, may also be
affected has been a matter of debate. In this article, the EAACI Joint
Task Force of the Working Group of Allergy, Asthma & Sports and the
Interest Groupf of Environmental & Occupational Allergy discusses the
current evidence regarding the health effects of both acute and chronic
exposures in different populations (work-related exposures, intensive
sports and recreational attendance) and identify the main
recommendations and unmet needs for research in this area.
Adverse events associated with weekly short course isoniazid and rifapentine therapy in pediatric patients with latent tuberculosis: a chart and literature review
Authors: Peck Gabrielle , Staat Mary , Huang Felicia Scaggs , Khalil Nadim , Boyce Catherine , Kohlrieser Cara , Schlaudecker Elizabeth
Published: February 2021

Background: Effective yet safe treatment of latent tuberculosis is
important for preventing the spread of tuberculosis and the progression
to active disease in pediatric patients. As of 2017, the short course
combination regimen of weekly isoniazid and rifapentine (3HP)
administered by directly observed therapy (DOT) has replaced 9 months of
isoniazid as the standard of treatment for latent tuberculosis in
pediatric patients. The literature, limited in size, has established the
3HP regimen’s superior safety and adherence. Methods: We completed a
retrospective chart review (n = 22) of pediatric patients at our
institution receiving this regimen between 2017 and 2019. Frequencies of
selected outcomes were compared to data collected in a literature
review. Results: In this retrospective chart review, pediatric patients
ages 2 to 20 years receiving 3HP with DOT for latent tuberculosis
experienced higher adverse event rates, more severe adverse events, and
higher treatment discontinuation than that which has been previously
reported in the literature. A possible explanation for this finding is
that our cohort’s race/ethnicity differed from the cohorts used in the
literature. Conclusions: Our data suggests that the short course
combination regimen for pediatric latent tuberculosis patients may have
a higher adverse event rate than previously established. Although this
sample size is small, this study urges further investigation of more
diverse cohorts to better establish the regimen’s safety and
tolerability.
Newly suggested shapes of impellers for stirring highly viscous fluids in vessels
Authors: Ameur Houari , Kamla Youcef
Published: February 2021

The power consumption and flow patterns generated in a cylindrical stirred tank are determined. The anchor impeller is used to ensure the agitation of highly viscous fluids. New modifications in the impeller design are introduced to improve the stirring rates. Firstly, the lower corner of the conventional anchor is replaced by an inclined segment to obtain Case No. 1. The number of segments was then increased to reach a closed circular shape (Case No. 2). Further increase in the number of segments was introduced to reach a perfect circular blade (Case No. 3) in the vertical direction. Finally, another circular horizontal blade was added to obtain Case No. 4. From the obtained results, Case No. 4 provided a great improvement in the circulation of fluid particles inside the vessel and generated the widest well-stirred region.
Investigation on the garnierite and limonite mixed laterite ore for nickel recovery

Published: February 2021

Laterite, as an important resource of nickel, has become the focus of development and utilization. This study adopted the method of mixing ore (garnierite and limonite) to increase the recovery rate of nickel in garnierite ore. The phase transformation of the two ores was investigated during the heating process; dehydroxylation and recrystallization were observed and the iron oxides phase was finally transformed into the iron-containing spinel. By changing the proportion of the two ores, increasing the iron content in the sample was beneficial to the reduction of nickel. Then, Fe2O3, Fe3O4, and Fe were used as the iron source to study the mechanism of the iron-bearing minerals in promoting the reduction of nickel. The results indicated that hematite and/or magnetite would react with amorphous silicate minerals to generate magnesioferrite and enstatite, thereby avoiding additional forsterite generation; moreover, the trevorite phase would be formed, which strengthens the aggregation of nickel and iron.
