Published: January 2022

BACKGROUND AND OBJECTIVES

Adolescents with cardiac disease are at risk for life-changing complications and premature death. The importance of advance care planning (ACP) in adults with congenital heart disease and in pediatric patients with HIV and cancer has been demonstrated. ACP preferences of adolescents with heart disease have not been evaluated. We describe ACP preferences of adolescents with heart disease and compare with those of their caregivers.

METHODS

Outpatient adolescents aged 12 to 18 years with heart failure, cardiomyopathy, heart transplantation, or who were at risk for cardiomyopathy, as well as their caregivers, completed self-administered questionnaires which evaluated participants’ opinions regarding content and timing of ACP discussions, preferences for end-of-life communication, and emotional responses to ACP.

RESULTS

Seventy-eight adolescents and 69 caregivers participated, forming 62 adolescent-caregiver dyads. Adolescents and caregivers reported that adolescent ACP discussions should occur early in the disease course (75% and 61%, respectively). Adolescents (92%) wanted to be told about terminal prognosis, whereas only 43% of caregivers wanted the doctor to tell their child this information. Most adolescents (72%) and caregivers (67%) anticipated that discussing ACP would make the adolescent feel relieved the medical team knew their wishes. Most caregivers (61%) believed that adolescents would feel stress associated with ACP discussions, whereas only 31% of adolescents anticipated this.

CONCLUSIONS

Adolescents and their caregivers agree that ACP should occur early in disease course. There are discrepancies regarding communication of prognosis and perceived adolescent stress related to ACP discussions. Facilitated conversations between patient, caregiver, and providers may align goals of care and communication preferences.
Österreichs friedlicher Kreuzzug 1839–1917
Authors: Haider-Wilson Barbara
Published: January 2022

Mit der vorliegenden Studie liegt ein quellenbasierter Beitrag zu jener Geschichte des „katholischen Österreich“ in seinem Zusammengehen von Kirche und Staat vor, die Grenzen überschritt und von Inter- wie Transnationalität geprägt war. Vor dem Hintergrund des europäischen Wettbewerbs um Einflussnahme im Heiligen Land – damals Teil des Osmanischen Reiches – werden jene Entwicklungen aufgezeigt, die zu einem verstärkten Engagement der katholischen Großmacht Habsburgermonarchie und zu einem unter dem Schlagwort vom „friedlichen Kreuzzug“ anwachsenden Interesse in weiten Teilen ihrer Bevölkerung geführt haben. Mit der Verknüpfung der Analysekategorien Außenpolitik, Gesellschaft und Mentalitäten werden neuere historiographische Zugänge für das Forschungsfeld fruchtbar gemacht. Im Zentrum der Betrachtung stehen staatlich-kirchliche Akteure (an der Spitze die Dynastie) und Institutionen: das Generalkommissariat des Heiligen Landes in Wien, die Franziskaner-Buchdruckerei, das Konsulat und das Hospiz in Jerusalem, das Malteserspital in Tantur, das Spital der Barmherzigen Brüder in Nazareth und die Missionsstation in Gaza. Neben der Darstellung der Rechtsgrundlagen, die einen wichtigen Rahmen vorgaben, stehen etwa Überlegungen zum „Mönchsgezänk an den Heiligen Stätten“ und zur Entwicklung des Pilger- und Vereinswesens. Mit dem Bezugspunkt Heiliges Land lassen sich für die Jahrzehnte von Metternich bis zum Ersten Weltkrieg Konjunkturen und das Streben nach Prestige ebenso erkennen wie eingeschränkte Handlungsräume; stets jedoch bildete das „Jerusalem-Milieu“ eine Konstante. Damit erfährt das von der späten Habsburgermonarchie auf dem internationalen Parkett gezeichnete Bild eine mehrdinensionale Ergänzung.
Response of durum wheat lines to the cause agent of leaf rust Puccinia triticina
Authors: Ivanova V. , Alexandrov T.
Published: January 2022

Аbstract. The response of 1262 durum wheat lines to the cause agent of leaf rust Puccinia triticina was studied. The investigation was carried under infection field conditions during 2013-2015 at Dobrudzha Agricultural Institute (DAI) – General Toshevo, Bulgaria. Over the years of investigation, a maximum high infection background was developed by the cause agent of the disease, including all pathogen pathotypes identified during this period. The race variability in the population of the pathogen during the period was determined at the Plant Pathology Laboratory of DAI according to a validated methodology for working with rusts. Seventy-one phenotypically different virulent pathotypes were established. Fifteen new races of P. triticina were also identified, which have not been present during the previous 15 years in Bulgaria. Seventeen lines and one cultivar with a certain degree of resistance to the pathogen were selected. The selected lines can be involved in the breeding programs for developing initial material with resistance to leaf rust P. triticina.

Published: January 2022

High-entropy oxides (HEO) with entropic stabilization and compositional flexibility have great potential application in batteries and catalysis. In this work, HEO thin films were synthesized by pulsed laser deposition (PLD) from a rock-salt (Co0.2Ni0.2Cu0.2Mg0.2Zn0.2)O ceramic target. The films exhibited the target’s crystal structure, were chemically homogeneous, and possessed a three-dimensional (3D) island morphology with connected randomly shaped nanopores. The effects of varying PLD laser fluence on crystal structure and morphology were explored systematically. Increasing fluence facilitates film crystallization at low substrate temperature (300 °C) and increases film thickness (60–140 nm). The lateral size of columnar grains, islands (19 nm to 35 nm in average size), and nanopores (9.3 nm to 20 nm in average size) increased with increasing fluence (3.4 to 7.0 J/cm2), explained by increased kinetic energy of adatoms and competition between deposition and diffusion. Additionally, increasing fluence reduces the number of undesirable droplets observed on the film surface. The nanoporous HEO films can potentially serve as electrochemical reaction interfaces with tunable surface area and excellent phase stability.

African communities in Australia reflect the rich cultural and religious diversity of the African continent. Despite their persistence and agency, many members from these communities continue to experience a ‘fractured belonging’ due to persistent issues of racism and exclusion; issues that have been exacerbated during the COVID-19 pandemic. Religious community groups and organizations have long played important roles in assisting new migrants with settlement and belonging in Australia, including African migrants. This article presents preliminary findings from an Australian Research Council project on religious diversity and social cohesion, drawing on census data and interviews with African-Australian community and religious leaders in Melbourne and Hobart, from Mauritian, Ghanaian, Ethiopian, Somalian and South Sudanese communities. It explores the roles that religion and spirituality play in both addressing and perpetuating issues of racism, trauma and displacement. It also examines the development of ‘relational belonging’ and diverse, complex and dynamic identities among African migrants in contemporary Australia. It argues the case for retelling the history of African migration to Australia, to subvert the myth of a white Christian nation that excludes non-white Australians. It centres African migrants’ lived experience narratives and theories of belonging developed by African scholars to counter narrow and negative stereotypes perpetuated by political and media discourses.
Leveraging African Spirituality and Popular Culture betwixt Africa and the African Diaspora
Authors: Adogame Afe , Amwe Ruth Vida
Published: January 2022

Ama McKinley’s article, ‘Beyoncé Serves African Spirituality in “Lemonade”’ in The Huffington Post (2016), depicts Beyoncé Knowles-Carter as ‘an artist of the Earth, using her stage and global influence to teach about the human condition, using symbology and language that is sacred and pronounced beyond a few approved circles’. This view partly epitomizes the resilience of African spirituality in the diaspora, where Beyoncé in ‘Lemonade’ invokes so much of the Yoruba tradition, grounded in African tradition, by offering a musical and visual journey through the African diaspora. African spiritualities touch on and imbue every facet of life and thus cannot be separated from quotidian, mundane thought. This article explores African spirituality as mostly concerned with the pursuit of cosmic balance and human flourishing through a matrix of worldviews, belief systems and ritual praxis. We employ Beyoncé Knowles-Carter’s music albums Lemonade and Black is King; and Ryan Coogler’s movie Black Panther to explore the intersectionality of African spirituality and popular culture in the African diaspora. We demonstrate how and to what extent the religious, moral, sociocultural and popular imaginaries linked to indigenous African worldviews and the African diaspora are continually contested and negotiated.

NOTE ON SUPER \((a,1)\)–\(P_3\)–ANTIMAGIC TOTAL LABELING OF STAR \(S_n\)
Authors: Rajkumar S. , Nalliah M. , Venkataraman Madhu
Published: January 2022

Let \(G=(V, E)\) be a simple graph and \(H\) be a subgraph of \(G\). Then \(G\) admits an \(H\)-covering, if every edge in \(E(G)\) belongs to at least one subgraph of \(G\) that is isomorphic to \(H\). An \((a,d)-H\)-antimagic total labeling of \(G\) is bijection \(f:V(G)\cup E(G)\rightarrow \{1, 2, 3,\dots, |V(G)| + |E(G)|\}\) such that for all subgraphs \(H'\) of \(G\) isomorphic to \(H\), the \(H'\) weights \(w(H') =\sum_{v\in V(H')} f (v) + \sum_{e\in E(H')} f (e)\) constitute an arithmetic progression \(\{a, a + d, a + 2d, \dots , a + (n- 1)d\}\), where \(a\) and \(d\) are positive integers and \(n\) is the number of subgraphs of \(G\) isomorphic to \(H\). The labeling \(f\) is called a super \((a, d)-H\)-antimagic total labeling if \(f(V(G))=\{1, 2, 3,\dots, |V(G)|\}.\) In [5], David Laurence and Kathiresan posed a problem that characterizes the super \( (a, 1)-P_{3}\)-antimagic total labeling of Star \(S_{n},\) where \(n=6,7,8,9.\)  In this paper, we completely solved this problem.
ON A CLASS OF EDGE-TRANSITIVE DISTANCE-REGULAR ANTIPODAL COVERS OF COMPLETE GRAPHS
Authors: Tsiovkina Ludmila Yu.
Published: January 2022

The paper is devoted to the problem of classification of edge-transitive distance-regular antipodal covers of complete graphs. This extends the classification of those covers that are arc-transitive, which has been settled except for some tricky cases that remain to be considered, including the case of covers satisfying condition \(c_2=1\) (which means that every two vertices at distance 2  have exactly one common neighbour).Here it is shown that an edge-transitive distance-regular antipodal cover of a complete graph with \(c_2=1\) is either the second neighbourhood of a vertex in a Moore graph of valency 3 or 7, or a Mathon graph, or a half-transitive graph whose automorphism group induces an affine  \(2\)-homogeneous group on the set of its fibres. Moreover,  distance-regular  antipodal covers of complete graphs  with \(c_2=1\) that admit  an automorphism group acting  \(2\)-homogeneously on the set of fibres (which turns out to be an approximation of the property of edge-transitivity  of such  cover), are described.   A well-known correspondence between distance-regular antipodal covers of complete graphs with \(c_2=1\) and geodetic graphs of diameter two that can be viewed as underlying graphs of certain Moore geometries, allows us to effectively restrict admissible automorphism groups of covers under consideration by combining Kantor's classification of involutory automorphisms of these geometries together with the classification of finite 2-homogeneous permutation groups.
Economic growth without welfare. The case of the impact of commodities on the Colombian economy
Authors: OVIEDO-GÓMEZ ANDRÉS FELIPE , VIAFARA JUAN MANUEL CANDELO
Published: January 2022

ABSTRACT Economic growth is not always related to social welfare. Therefore, this paper takes the case of the Colombian economy that has a strong dependence on commodity exploitation to identify the impacts of different commodities such as oil, coffee, coal, and nickel over economic variables. The results show that the increase in prices of commodities generates significant impacts on economic activity in variables such as GDP and investment. Also, there are no significant impacts on variables that provide welfare to individuals as total consumption or the unemployment rate.
A keyword on the footer: the Furtadian and the (re)current meaning of structural reforms
Authors: Cardoso Guilherme Silva
Published: January 2022

ABSTRACT A semantic change has occurred in the scope of structural reforms’ term. This article reviews Celso Furtado’s work, in particular, the ones related to this specific topic, and compares it with the current literature. It appears that structural reforms in the Furtadian conception connoted base transformations and were guided by the developmentalism school of thought. Nowadays, it is of general knowledge that, under the new-institutionalist influence, “structural reforms” are associated with liberal policies for monitoring fiscal consolidations, without consensus as to the power of effectiveness. The effort to rescue and understand the original conceptions of certain keywords in the economic development literature, as well as the way in which their interpretations and practices modify over time, is shown to be of paramount importance as the capitalist system struggle to find ways of adapting itself to the current situation of developing economies.

Published: January 2022

RESUMO A pesquisa tem como objetivo apontar as diferenças e similitudes entre Corporate Venture Capital (CorpVC) e Aceleradores Corporativos (AC), mecanismos estes de colaboração entre empresas maduras e Startups. A pesquisa apontou que o fenômeno de Aceleradores Corporativos e de Corporate Venture Capital são práticas de inovação aberta, que podem ser semi-institucionalizadas em empresas que possuam a intenção de buscar inovação em ambientes externos. O fato de CorpVC e AC serem baseados em objetivos estratégicos, e não só financeiros, os diferenciam das outras modalidades de investimentos feitas diretamente em empresas, no entanto, percebeu-se que ambas as estratégias têm diferenças cruciais, que, se vistas anteriormente pela empresa madura, podem ser mais bem aplicadas, garantindo o índice de sucesso maior, baseado no propósito e objetivo da Corporação financiante.

Patterns of external insertion in global value chains: a comparative analysis between Brazil and China
Authors: Araújo Caroline Giusti de , Diegues Antonio Carlos
Published: January 2022

ABSTRACT The international trade literature has shown the benefits of the international fragmentation of production for developing countries. However, there are considerations about the hierarchy and control in Global Value Chains (GVCs). Thus, this research aims to evaluate the Brazilian and Chinese international insertion in GVCs by proposing an index about technological sophistication in exports (qtech) by technological intensity for 2005-2015. The results pointed out that the integration in GVCs and technological sophistication have been directed towards technological clusters in which Brazil has revealed comparative advantages, while China has been moving towards technological clusters with dynamic comparative advantages.
Restrição de sobrevivência e regulação financeira: uma nova perspectiva minskyana
Authors: Torres Filho Ernani Teixeira , Martins Norberto Montani
Published: January 2022

RESUMO Este artigo aponta a importância do conceito de “restrição de sobrevivência” proposto por Minsky na gênese da introdução da regulação financeira moderna. O risco de colapsos sistêmicos nos sistemas baseados em moeda fracionários levou os Estados a suspenderem a aplicação da penalidade relacionada à restrição de sobrevivência - a falência - aos bancos comerciais. Essa medida permitiu que esses agentes financeiros pudessem, na busca por lucros, tomar decisões alocativas ainda mais arriscadas, aumentando a fragilização financeira (moral hazard). Para mitigar esse comportamento adverso, a regulação financeira procura todo o tempo estabelecer limites que emulem o comportamento que esses agentes deveriam ter caso ainda estivessem sujeitos à restrição de sobrevivência. Essas regras precisam ser permanentemente revistas de modo a acompanhar a evolução dos mercados financeiros sob pena de se tornarem impotentes para evitar situações de instabilidade financeira.
Política monetária no Brasil em tempos de pandemia
Authors: Feijó Carmem , Araújo Eliane Cristina , Bresser-Pereira Luiz Carlos
Published: January 2022

RESUMO O artigo discute a determinação da inflação no Brasil, sobretudo a partir da grande recessão de 2015-2016, para avaliar a adequação da política de manipulação de taxas de juros para controlar a alta de preços decorrente de pressão permanente de custos. O ônus de usar a taxa de juros para combater inflação de custo é criar um nível altamente convencional da taxa de juros real, o que, em uma economia financeirizada, beneficia a classe dos rentistas. À luz da macroeconomia pós-keynesiana, a convenção de alta taxa de juros mantém a economia com baixa taxa de crescimento e baixa taxa de investimento, o que no caso da economia brasileira tem resultado em regressão da matriz produtiva e estagnação da produtividade e ambos contribuem para perpetuar as pressões de custo sobre os preços. A análise empírica corrobora a discussão de que a inflação recente teve sua origem em pressões de custos sobre as quais o impacto da taxa de juros para seu controle é limitado. Complementamos a análise empírica testando a resposta à taxa de juros SELIC das variáveis utilizadas para explicar a flutuação dos preços livres e dos preços administrados: índice de preços de commodities, taxa de câmbio e nível de atividade. Conforme esperado, o impacto da alta da taxa de juros valoriza a taxa de câmbio, favorecendo o controle da inflação e reduzindo o nível de atividade, mas não tem impacto no índice de preços das commodities.
Survival of Hybrid Laminate Veneers using two different tooth preparation techniques: Randomized Clinical Trial
Authors: Attia Yara Sayed , Sherif Rana Mahmoud , Zaghloul Hanaa Hassan
Published: January 2022

Abstract The aim of this study was to evaluate the survival of laminate veneers constructed using a recent polymer-infiltrated ceramic network material following the aesthetic pre-evaluative temporary (APT) technique of tooth preparation in comparison to traditional technique. Six patients received 54 laminate veneers. They were divided into two equal groups (n=27) according to the technique of tooth preparation: group T: traditional technique and group A: aesthetic pre-evaluative temporary technique. VITA ENAMIC material was used for CAD/CAM construction of laminate veneers. Cementation was performed using a light cured resin cement. The laminate veneers were evaluated at baseline, after 3, 6 and 12 months according to the modified United States Public Health Service (USPHS) criteriea. The data was collected, tabulated and statistically analyzed. Secondary caries, endodontic complications, cracks and loss of retention were not noted in any laminate veneer. Extensive fractures were not detected in both study groups through the study period. There was a statistically significant decrease of color match criteria between the two groups at the 6 and 12 months recalls. Based on this study, both preparation techniques resulted in successful clinical performance. After 12 months, all the veneers in both groups showed no post-operative sensitivity and all patients were highly satisfied regarding their veneers. However, there was a deterioration in color match criteria through the study period in both study groups.

Published: January 2022

Abstract This study aimed to investigate the effect of surface roughness (polished vs. CAD/CAM milling simulation) on impact strength of five dental ceramics for manufacturing CAD/CAM monolithic restorations. Specimens of five ceramics (FC- feldspathic glass-ceramic; PICN- polymer-infiltrated ceramic-network; ZLS- zirconia-reinforced lithium silicate glass-ceramic; LD- lithium disilicate glass-ceramic; YZ- yttria-stabilized tetragonal zirconia polycrystal ceramic) to be tested under impact (15×10×2mm3; n= 15) were divided into two groups, according to surface treatment: polishing (pol) and grinding (gri) as CAD/CAM milling simulation. Impact strength was tested using the Dynstat method. Roughness, topographic, fractographic and finite element analyses were performed. The impact strength data were analyzed by Weibull, and Pearson correlation was used to correlate roughness and impact strength data. The CAD/CAM milling simulation led to significantly (p<0.05) greater roughness (Ra and Rz) and statistically reduced the impact strength for PICN (polPICN= 4.59 to griPICN= 1.09; ±76% decrease), for LD (polLD= 17.69 to griLD= 10.09; ±43% decrease) and for YZ (polYZ= 74.99 to griYZ= 20.67; ±72% decrease) ceramics; and also promoted a more irregular topography with scratches and grooves. Fractographic and FEA analyses depicted the origin of failure at the higher stress concentration side during the impact test, where the pendulum impacted. The CAD/CAM milling simulation significantly decreased the impact strength of the evaluated ceramic materials.

Published: January 2022

Abstract The aim of this study was to evaluate surface wear, presence of microcracks and surface irregularities of WaveOne (WO) and WaveOne Gold (WOG) instruments before and after multiple uses. Eight Primary instruments of the WO and WOG systems were evaluated, each one was used to prepare six mesial canals of extracted human mandibular molars. The surface of the instruments was evaluated before use (T0), after instrumentation of three (T1) and six (T2) root canals. Surface wear was analyzed using a three-dimensional optical profiler and the presence of microcracks and surface irregularities were evaluated using a tabletop scanning electron microscopy. The Friedman test was used to assess surface wear and Kruskal-Wallis test to evaluate the presence of microcracks and surface irregularities, with a 5% significance level. There was a significant increase in wear in both groups at T2, compared to T0 (p=0.0003). The surface wear after instrumentation of six canals (T2-T0) was statistically greater in the WOG group, than in the WO group (p=0.02), where the presence of microcracks was significantly greater and increased after multiple uses (p<0.05). The presence of surface irregularities in the cutting blade before and after use was statistically greater in the WOG group than WO group (p<0.05). Wear of the cutting blade, microcracks and surface irregularities were observed on the surface topography of all the instruments after multiple uses. These surface changes may affect the cutting efficiency of WOG files and increase the risk of fracture of WO files.

Authors: Pedrosa Marlus da Silva , Nogueira Fernando Neves , Sipert Carla Renata
Published: January 2022

Abstract This study investigated the cytotoxicity and release of Transforming Growth Factor Beta 1 (TGF-β1) from cultured human apical papilla cells (APCs) after application of four bioactive materials. Culture of APCs was established and used for cytotoxic and quantitative assays. Extracts of Biodentine, Bio-C Repair, MTA Repair and White MTA were prepared and diluted (1, 1:4 and 1:16) and used for MTT assays up to 72 h. Total TGF-β1 was quantified by ELISA. Data were analyzed by ANOVA and Tukey’s test (α = 0.05). For Biodentine, at 24 h and 48 h, cell viability was lower than control (p < 0.05). At 72 h, only undiluted extract of Biodentine were cytotoxic (p < 0.05). At 24 h, a cytotoxic effect was found for undiluted and 1:4 dilution of Bio-C Repair (p < 0.05). At 48 h, however, Bio-C Repair at 1:4 and 1:8 dilution showed higher cell viability (p < 0.05). At 24 and 48 h, the cell viability for undiluted MTA Repair were higher than control (p < 0.05). For White MTA, at 24 and 48 h, all dilutions were cytotoxic (p < 0.05). All cements led to reduced release of total TGF-β1 from the APCs (p < 0.05). In conclusion, cell viability varied depending on the material and dilution. Only Bio-C repair and MTA repair led to higher cell viability of APCs. All materials induced a decrease in the release of total TGF-β1 from the APCs.
Is the Er:YAG laser affect the surface characteristics and bond strength of Y-TZP?
Authors: Souza-Filho Celso Bernardo de , Moris Izabela C. M. , Colucci Vivian , Faria Adriana Cláudia Lapria , Gomes Érica A.
Published: January 2022

Abstract This study evaluated the surface characteristics and bond strength of Y-TZP treated with Er:YAG laser at different focal distances. 120 Y-TZP blocks were divided into five groups (n=24), according to the surface treatment: no treatment (C-); sandblasting with silica-coated aluminum oxide particles (C+); and Er:YAG laser application at focal distances of 1mm (Er:YAG-1), 4mm (Er:YAG-4), and 7mm (Er:YAG-7). Surface characteristics were analyzed using Vickers microhardness, confocal laser microscope, scanning electron microscopy (SEM), and X-ray diffractometer (XRD). For the bond strength test, 100 Y-TZP blocks were subdivided into two subgroups (n=10), according to the resin cement used: with (MDP+) or without 10-methacryloyloxydecyl dihydrogen phosphate (MDP-). The Vickers microhardness and surface roughness were analyzed by one-way ANOVA and bond strength by two-way ANOVA and Tukey's test for both (α=0.05). Vickers microhardness differences were not observed between the groups (p>0.05); C+ showed higher surface roughness values. SEM images showed micromorphological differences between the groups. The XRD data detected tetragonal crystals for C- and, for the other groups, tetragonal and monoclinic peaks. For bond strength, no statistically difference significance were observed among the cements with or without MDP (p>0.05) but showed significant difference between the surface treatments (C+ > C- = Er:YAG1 > Er:YAG4 = Er:YAG7) (p<0.05). Suggested that the Er:YAG laser cannot replace conventional treatment with aluminum oxide particles and the presence of MDP in the resin cement had no influence on the bond strength.

Published: January 2022

ABSTRACT: Clubroot disease, caused by Plasmodiophora brassicae, limits the production of Brassica spp. worldwide. Little is known about the factors related to the development of the disease in kale (Brassica oleracea var. acephala) plants and in crops in mountainous areas under tropical conditions. This study examined the severity of clubroot in kale crops as well as identify potential flaws in management and the soil and relief factors related to its occurrence. The study was conducted in 24 kale fields in the mountainous region of Rio de Janeiro (Brazil). Soil and kale growth management practices adopted in the region were identified and samples of soil and plants were collected. Subsequently, soil and relief attributes, disease severity, biomass and nutrient and Al contents and accumulation in the plants were determined. There was a high spread of the pathogen in the areas. Inappropriate and recurrent practices in the region were detected, e.g., sequential cultivation of host species, low adoption of soil fertility analysis and liming and conservation practices, and community use of agricultural machinery and implements without prior cleaning. The disease was associated with more acidic soils, subject to greater water accumulation and with high levels of Al3+ as well as with higher Al contents and accumulation in the roots. Management practices must be adopted in the region to reduce the potential inoculum of P. brassicae and to increase soil fertility.

Published: January 2022

Abstract Objective: To identify the main nursing diagnoses and interventions in children in the immediate postoperative period of palatoplasty. Method: Documentary and retrospective study, developed in a Brazilian public and tertiary hospital, between August and September 2020. Children who underwent only palatoplasty, between January and December 2019, aged between 10 and 24 months, were included. Those with medical syndromes and/or comorbidities were excluded. The Theoretical Framework of Basic Human Needs and the NANDA International and Nursing Interventions Classification Taxonomies were used. Data underwent descriptive statistical analysis. Results: The sample consisted of 126 children. Psychobiological needs such as oxygenation, hydration, nutrition, elimination, cutaneous-mucosal and physical integrity, pain and environmental perception predominated. Based on them, nine nursing diagnoses, with four focusing on the problem and five on risk, as well as 17 interventions, were identified. Conclusion: The use of standardized languages to identify affected human needs and, based on them, diagnoses and interventions, favored clinical reasoning for the construction and organization of clinical nursing practice.

Abstract Objective: To verify researchers-nurses’ knowledge about trends in scientific publishing and good research practices. Method: A descriptive study carried out through an online survey with 197 nurses holding master’s and/or doctoral degrees from all Brazilian regions. To raise knowledge, a validated, self-administered and anonymous questionnaire with 18 questions on the subject was used. Descriptive and inferential analyzes were performed on researchers’ scores (Mann-Whitney test). Results: Among the specific questions, the mean of correct answers was 7.1: 6.4 for master’s and 7.4 for doctoral degree holders. There was a significant difference in the mean of correct answers between masters and doctors (p = 0.025), and between productivity scholarship holders and non-scholarship holders (p = 0.021), according to mean difference tests. Questions about predatory editorial practices were those in which researchers had the worst knowledge. Conclusion: We identified that, regardless of the education level (master’s or doctoral degree), nurses have little knowledge about the topics studied, which can compromise the quality of production and the scientific vehicles used to disseminate this knowledge.

Abstract Objective: To understand the challenges experienced by Portuguese workers in humanitude care for institutionalized elderly people during the pandemic. Method: This is a qualitative study, supported by reflections on the Humanitude Care Methodology, carried out with workers from different areas in a nursing home for elderly people in Portugal. Data collection took place between September and October 2020, from individual and online interviews. The categorization proposed by Bardin was adopted as the analysis technique. Results: Three categories emerged: (1) self-protection and of the other with the subcategories fear of being contaminated and fear of contaminating the elderly; (2) maintenance of affective relationships, broken down into the subcategories absence of family members in the nursing home and personal protective equipment as a barrier to communication and approximation; and (3) confinement of the elderly who attended the Day Center, with the subcategories lack of family support/loneliness and change in the elderly’s routine. Conclusion: The main challenges experienced by Portuguese workers are related to the necessary changes in the performance of care practices due to the use of personal protection that was not used before, limitations in affective relationships, and restrictions in interaction spaces.

Published: January 2022

Abstract Objective: To perform a systematic review of the health economic evidence on the care of children and adolescents with complex clinical conditions, comparing groups included and not included (control group) in palliative care at the end of life. Data source: The seven databases searched were PubMed, Embase, Web of Science, Cochrane Library, Virtual Health Library–Latin American and Caribbean Health Sciences Literature (VHL-LILACS), EBSCOhost, and Paediatric Economic Database Evaluation, following recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement, from January 1979 to November 2020. The review included studies of patients under 18 years of age with complex clinical conditions that compared a palliative care group with a control group. The economic outcomes analyzed were length and place of stay at the end of life (home, hospice, ward, intensive care unit, emergency room), diagnostic and therapeutic procedures performed, and health-related costs. The exclusion criteria were: studies without a matched control group, conference/congress abstracts, letters to the editor, editorials, comments, qualitative studies, narrative reviews, studies with ten or fewer participants in each group, articles published in languages other than English, Portuguese, or Spanish. Data synthesis: Out of the 518 articles identified, 4 met the inclusion criteria. We found evidence of direct economic benefits, such as reduced health costs, indirect savings, and protection of patients from undergoing invasive procedures, surgeries, and costly therapies, which cause greater suffering at the end of life. Therefore, participating in a palliative care program saved financial and technological resources, besides increasing the frequency of deaths at home and improving the quality of life. Conclusions: Public and private policies to promote palliative care represent better efficiency when allocating available health care resources.
On some uncertainties related to static liquefaction triggering assessments
Authors: Reid David , Dickinson Simon , Mital Utkarsh , Fanni Riccardo , Fourie Andy
Published: January 2022

Static liquefaction has been identified as the cause of several recent tailings storage facility (TSF) failures. Partially based on the investigations carried out, significant advances on the analysis of static liquefaction triggering (SLT) have been made. These include applications of critical-state-based models in a stress–deformation framework to identify if in situ conditions are approaching a level where SLT could occur. However, several important uncertainties remain. In this work, three of these uncertainties (geostatic stress ratio K0, intermediate principal stress ratio and principal stress angle from vertical) were investigated, along with their effects (both independently and in conjunction) on the identification of SLT and slope failure. These uncertainties were examined through a series of numerical analyses of an idealised TSF. Various values of K0 were used to examine their effect on SLT, while different approaches were taken to assess the potential effects of the intermediate principal stress ratio and the principal stress angle from vertical on instability. This work revealed that the current state of knowledge in these areas is such that significant uncertainty seems unavoidable in attempting to identify exactly when a particular slope may undergo SLT. Experimental and in situ test programmes that may be useful in reducing this uncertainty are outlined.
Precise grading of surrounding rock based on numerical calculation of jointed rock mass
Authors: Huang Dan , Li Xiao-Qing , Song Wen-Chao
Published: January 2022

In this study, grading of surrounding rock was based on rock mass basic quality (BQ) according to Chinese specifications. A numerical approach was used to construct a synthetic rock mass model (SRMM) to represent the jointed rock mass and then obtain the strength of the rock mass. To construct a discrete fracture network, intact rock was represented by the bonded particle model and joint behaviour was represented by a smooth joint model. In a case study (Hongtuzhang tunnel), the micro properties of granite cores with different degrees of weathering were determined and the representative elementary volume of the surrounding rock was set as 15 × 15 m. Five slightly weathered, three slightly to moderately weathered and two moderately weathered granite surrounding rock mass models were established based on the probability distribution of joint sets in each borehole, and the conversion BQ value was acquired according to the calculated strength of the SRMM. The surrounding rock grades obtained using geological surveys were found to be higher than those predicted by the numerical method. The numerical calculation was consistent with actual excavation of rock mass at a borehole.
Analysis of shear-critical reinforced concrete columns under variable axial load

Published: January 2022

Older existing reinforced concrete (RC) frame structures often contain shear-dominated vertical structural elements, which can experience loss of axial load-bearing capacity after a shear failure, hence initiating progressive collapse. An experimental investigation previously reported by the authors focused on the effect of increasing compressive axial load on the non-linear post-peak lateral response of shear, and flexure–shear, critical RC columns. These results and findings are used here to verify key assumptions of a finite-element model previously proposed by the authors, which is able to capture the full-range response of shear-dominated RC columns up to the onset of axial failure. Additionally, numerically predicted responses using the proposed model are compared with the experimental ones of the tested column specimens under increasing axial load. Not only global but also local response quantities are examined, which are difficult to capture in a phenomenological beam–column model. These comparisons also provide an opportunity for an independent verification of the predictive capabilities of the model, because these specimens were not part of the initial database that was used to develop it.
Comparison of Prognostic Computed Tomography Scores in Geriatric Patients with Traumatic Brain Injury: A Retrospective Study
Authors: BOZAN Öner , ALTUNOK İbrahim
Published: January 2022

Aim
This study aimed to compare the Rotterdam and Helsinki computed tomography (CT) scoring systems for predicting the 30-day mortality after traumatic brain injury (TBI) in the geriatric population.
Materials and Methods
Patients aged ≥65 years presenting to the emergency department with trauma-related complaints were retrospectively scanned using International Classification of Disease codes, and patients with isolated head trauma examined using brain CT were included. Demographic data including age, gender, trauma mechanisms, Glasgow Coma Scale (GCS) score at the time of admission, light reflex information, intubation, and surgery status, and emergency department outcomes were recorded. Brain CT images were investigated to calculate the Rotterdam and Helsinki CT scores and the relationship between them was examined.
Results
Of the 890 included patients, 403 (45.3%) were male. Overall, 683 patients fell from a height of <1 m and 195 suffered injuries by hitting or direct impact. Further, the 30-day mortality rate was examined, revealing that 868 patients were alive and 22 patients died. Mortality rate was 3.7% for males and 1.4% for females. The Rotterdam and Helsinki CT scores and 30-day mortality was analyzed using receiver operating characteristic curve analysis, and the area under the curve was found as 0.564 and 0.603, respectively. The specificity of Rotterdam and Helsinki CT scoring systems in predicting 30-day mortality was 99.08% and 99.19%, respectively.
Conclusion
The use of CT scoring systems such as Rotterdam and Helsinki in the geriatric population presenting with TBI allows us to predict 30-day mortality.

Published: January 2022

Aim: Tumor microenvironment plays an important role in onset and progression of the cancer. Tumor budding (TB), tumor stroma and tumor-infiltrating lymphocytes are component of the tumor microenvironment. It was aim to determine the relationship of TB, tumor stroma ratio (TSR) and tumor-infiltrating lymphocytes (TILs) with clinicopathological prognostic parameters in gallbladder adenocarcinoma.
Materials and Methods: Thirty cholecystectomy cases that were diagnosed as adenocarcinoma between 2010 and 2020, that did not receive neoadjuvant therapy and of which archive slides could be accessed, were included in the study. TB, TSR and TILs were evaluated. A p<0.05 value was statistically significant.
Results: High TB score was significantly associated with higher histological grade (p=0.008), higher pT stage, lymphovascular invasion (LVI) (p=0.038), lymph node metastasis (p=0.046) and distant metastasis (p=0.036) . Patients with high TB scores had a shorter overall survival (p<0.001). In the high TILs group, lower histological grade (p=0.004), less LVI (p=0.029), fewer distant metastases (p=0.021) and lower TSR (p=0.008) were detected. Increased TCR was associated with higher histological grade (p=0.015) and increased distant metastasis (p=0.013). There was no significant effect of TCR on overall survival (p=0.239).
Conclusion: TB can be used as a novel prognostic histological characteristic in the gallbladder cancer patients. We have concluded that it is early to recommend TILs and TSR as the prognostic indicators in gallbladder cancers. In the future, further studies can be conducted on a larger number of GBC cases with a multicenter participation to clarify the prognostic value of TILs and TSR.
