Central Bank Digital Currency: research streams – a literature review
Authors: Šapkauskienė Alfreda , Prialgauskaitė Ineta
Published: May 2023

Each type of payment - whether it would be coins and notes, electronic bank transfer, or remittance via fractions of bitcoin - could lead to a considerable number of benefits, as well, could possess a substantial number of risks or even threats to the current financial system and stability. The relatively recent concept of payment - cryptocurrencies, especially central bank digital currencies (CBDCs) - from a historical point of view, remains a mystery with only a few central banks to date launching these particular digital currencies. Since fundamental decisions in the development of CBDCs are taking place nowadays, it highlights the importance of a thorough review of already existing theoretical research with a view to determining various assessments and blind spots, before introducing CBDCs in the wider markets and usage. The scientific literature about CBDC was analysed using an extensive and systematic study of available research publications, their categorization, and summarizing. The authors offer a new glance toward a systemization of available scientific literature with a focus on CBDC. This novel suggestion of dividing research areas supports the idea of the end-to-end product life-cycle and comes into four different groups: motivations, design features, demands, and final impact on monetary sovereignty and the financial system as a whole. The unknown level of CBDC’s demand or expression of design features encourages researchers to consider various theoretical implications before CBDC will be creating major shifts in the banking industry or financial ecosystem.

The aggressive war waged by the Russian Federation caused significant material losses to Ukraine. According to preliminary estimates of the World Bank, as of the beginning of December 2022, the cost of the post-war reconstruction of Ukraine amounted to 500-600 billion euros, while the full recovery of Ukraine requires the development of a large plan. In this connection, there is a need to solve the problem of real compensation for damages caused to Ukraine by the aggressive war waged by the Russian Federation, which is new and insufficiently researched by representatives of legal science. Based on the analysis, it was concluded that the Charter of the United Nations; The text of the articles on the responsibility of states for internationally wrongful acts, adopted by the Resolution of the General Assembly of the United Nations Organization dated 12.12.2001 No. 56/83, which is a source of customary international law; the interim decision of the International Court of Justice of the United Nations of 16.03.2022 on the immediate halt of the military invasion of the Russian Federation on the territory of Ukraine; The resolution of the General Assembly of the United Nations “Aggression against Ukraine” dated 02.03.2023, which condemns the military invasion of the Russian Federation into Ukraine, together create the prerequisites for the recognition of all military actions committed on the territory of Ukraine by the armed forces of the aggressor state, such that violate current international law and provide grounds for imposing on the Russian Federation the obligation to compensate all damages caused by its military aggression. It was emphasized that the creation of an international regulatory framework regarding the responsibility of the Russian Federation should end with the adoption of a multilateral agreement with the participation of Ukraine as a state that suffered from the armed aggression of the Russian Federation, and other states that agree to search for and confiscate the assets of the Russian Federation, with the aim of using them for real compensation for damages. It is substantiated that the main types of responsibility of the Russian Federation include compensation for property and moral damage; direct compensation for damages caused by the internationally illegal actions of the Russian Federation will take place in the form of restitution (substitution), compensation and satisfaction both separately and by combining them, as well as by charging interest; the decision on the distribution of monetary compensation for damaged or destroyed objects of immovable and movable property, as well as compensation for moral damage and lost profit to the injured persons should be carried out in compliance with the principles of social justice and proportionality.

OBJECTIVES

Many interventions in bronchiolitis are low-value or poorly studied. Inpatient bronchiolitis management is multidisciplinary, with varying degrees of registered nurse (RN) and respiratory therapist (RT) autonomy. Understanding the perceived benefit of interventions for frontline health care personnel may facilitate deimplementation efforts. Our objective was to examine perceptions surrounding the benefit of common inpatient bronchiolitis interventions.

METHODS

We conducted a cross-sectional survey of inpatient pediatric RNs, RTs, and physicians/licensed practitioners (P/LPs) (eg, advanced-practice practitioners) from May to December of 2021 at 9 university-affiliated and 2 community hospitals. A clinical vignette preceded a series of inpatient bronchiolitis management questions.

RESULTS

A total of 331 surveys were analyzed with a completion rate of 71.9%: 76.5% for RNs, 57.4% for RTs, and 71.2% for P/LPs. Approximately 54% of RNs and 45% of RTs compared with 2% of P/LPs believe albuterol would be “extremely or somewhat likely” to improve work of breathing (P < .001). Similarly, 52% of RNs, 32% of RTs, and 23% of P/LPs thought initiating or escalating oxygen in the absence of hypoxemia was likely to improve work of breathing (P < .001). Similar differences in perceived benefit were observed for steroids, nebulized hypertonic saline, and deep suctioning, but not superficial nasal suctioning. Hospital type (community versus university-affiliated) did not impact the magnitude of these differences.

CONCLUSIONS

Variation exists in the perceived benefit of several low-value or poorly studied bronchiolitis interventions among health care personnel, with RNs/RTs generally perceiving higher benefit. Deimplementation, educational, and quality improvement efforts should be designed with an interprofessional framework.
To resuscitate or not to resuscitate? The crossroads of ethical decision-making in resuscitation in the emergency department
Authors: Kumar Nirdosh , Fatima Meraj , Ghaffar Sara , Subhani Faysal , Waheed Shahan
Published: May 2023

Emergency physicians (EPs) working in low-resource settings, where patients mainly bear the cost of healthcare delivery, face many challenges. Emergency care is patient-centered and ethical challenges are numerous in situations where patient autonomy and beneficence are fragile. This review discusses some of the common bioethical issues in the resuscitation and postresuscitation phases of treatment. Solutions are proposed and the necessity for evidence-based ethics and unanimity on ethical standards is emphasized. After a consensus was reached on the structure of the article, smaller groups of authors (2–3) wrote narrative reviews of ethical issues such as patient autonomy and honesty, beneficence and nonmaleficence, dignity, justice, and specific practices and circumstances such as family presence during resuscitation after discussions with senior EPs. Ethical dilemmas were discussed, and solutions were proposed. Cases related to medical decision-making by proxy, financial constraints in management, and resuscitation in the face of medical futility have been discussed. Solutions proposed include the early-stage involvement of hospital ethics committees, financial assurance in place beforehand, and allowing some leverage on a case-to-case basis when care is futile. We recommend developing evidence-based national ethical guidelines and incorporating societal and cultural norms with autonomy, beneficence, nonmaleficence, honesty, and justice principles.
Current challenges in adopting machine learning to critical care and emergency medicine
Authors: Kang Cyra-Yoonsun , Yoon Joo Heung
Published: May 2023

Over the past decades, the field of machine learning (ML) has made great strides in medicine. Despite the number of ML-inspired publications in the clinical arena, the results and implications are not readily accepted at the bedside. Although ML is very powerful in deciphering hidden patterns in complex critical care and emergency medicine data, various factors including data, feature generation, model design, performance assessment, and limited implementation could affect the utility of the research. In this short review, a series of current challenges of adopting ML models to clinical research will be discussed.
Regional payment agreements: An alternative to currency convertibility?
Authors: Bruchanski Marcelo , Molinari Andrea
Published: May 2023

Regional Payment Agreements (RPAs) replicate, on a regional scale, John M. Keynes’s proposal at the Bretton Woods Conference, based on the recording and subsequent clearing of transactions. The analysis of the three “founding” RPAs from the Golden Age (Finland-USSR, European Payments Union and the LAFTA-LAIA Agreement on Reciprocal Payments and Credits) suggests that, in general, these agreements fulfiled their objectives: saving foreign currency and promoting trade. Hence, RPAs would present an alternative to currency convertibility for current account transactions.

Published: May 2023

Let G be a finite group and let X be a compact G-space. In this note we study the (Z+ × Z/2Z)-graded algebra

FqG (X) = ⊕n ≤ 0 qn · KG∫Gn(Xn) ⊗ C,

defined in terms of equivariant K-theory with respect to wreath products as a symmetric algebra, we review some properties of FqG (X) proved by Segal and Wang. We prove a Kunneth type formula for this graded algebras, more specifically, let H be another finite group and let Y be a compact H-space, we give a decomposition of FqG × H (X × Y) in terms of FqG (X) and FqH (Y). For this, we need to study the representation theory of pullbacks of groups. We discuss also some applications of the above result to equivariant connective K-homology.

Authors: Valderrama–Pomé A.
Published: May 2023

El trematodo Fasciola hepatica genera la parasitosis zoonótica denominada fascioliasis, que aqueja especialmente a niños de edad escolar pertenecientes a poblaciones del sector rural donde se practica la agricultura. El objetivo de la revisión fue mostrar la realidad de la fascioliasis en Perú frente al resto del mundo y sus factores asociados. Se efectuó un estudio de carácter bibliométrico, descriptivo y transversal, recopilando publicaciones hasta 2021, como artículos originales, comunicaciones cortas y reporte de casos, utilizando como estrategia de pesquisa en internet la combinación de palabras clave y operadores booleanos empleados en las bases de datos de Scopus, Science Direct, Web of Knowledge, Proquest y Scielo, así como tesis de repositorios universitarios. Se encontró que los países con mayor prevalencia son Perú, Bolivia, Camboya y Venezuela. La prevalencia de fascioliasis en niños de edad escolar en Perú es superior a 15% y se incrementa con la altitud de las zonas endémicas. La prevalencia promedio en ovinos es hiperendémica y en bovinos y caprinos, mesoendémica. Además, edad y género son posibles factores asociados a fascioliasis, así como las características de su vivienda, ingestión de verduras y bebidas crudas, convivencia con animales domésticos, coinfección con parásitos intestinales, algunos signos clínicos y el estado nutricional. En conclusión, la fascioliasis es una parasitosis de distribución mundial que aún presenta problemas de diagnóstico, debido a que la sintomatología obedece a la fase que atraviesa la infección y a cuadros similares presentados por otras afecciones.

Published: May 2023

Con el proyecto que fundamenta este artículo se desarrolló un análisis detallado del destino final de animales silvestres por parte la autoridad ambiental, con enfoque en los procesos de liberación en los departamentos amazónicos del Amazonas, Caquetá y Putumayo, entre 2019 y 2021, para proponer alternativas efectivas de abordaje y manejo de la situación. Los datos fueron directamente requeridos a la  Corporación para el Desarrollo Sostenible del Sur de la Amazonía (Corpoamazonía), y a partir de  estos se desarrolló manejo estadístico para posteriormente interpretar los resultados obtenidos a la luz de la literatura académica publicada sobre el tema y la normatividad vigente relacionada. Como producto de la investigación, se identifica que la principal proveniencia de especímenes se establece en la entrega voluntaria (65,59%),seguido del rescate o traslado (27,87%), y decomiso, incautación, aprehensión o medida preventiva (3,96%). Como su principal destino final se identificó la liberación (45,21%). Del total de liberaciones entre 2019 y 2021, solo en 50 (4,09% de los casos), se consignó algún tipo de indicación del lugar o la ubicación específica donde se llevó a cabo, sin mención del procedimiento de caracterización del hábitat o genética del espécimen, o seguimiento posliberación, por lo que resulta necesario potenciar otras formas de uso de la fauna silvestre que permitan reducir el margen de incertidumbre.

Az orvostudomány az elmúlt évtizedekben hihetetlen mértékű fejlődésen ment
keresztül, a szakterületek határai megváltoztak, további specializációk jöttek
létre, új szakterületek alakultak. Ebbe a folyamatba illeszkedik a
rehabilitációs medicina megszületése, fejlődése, jelenlegi kompetenciáinak
kialakulása. Egy önálló, szemléletében egységes, új interdiszciplináris klinikai
szakterület jött létre Magyarországon. A közlemény célja a rehabilitációs
medicina elmúlt húsz évben történt magyarországi fejlődésének, eredményeinek
bemutatása. A rehabilitációs medicina hazai közleményeinek, adatainak
felhasználásával az elért eredmények leíró bemutatása történt, szisztematikus
elemzés nélkül. Az elmúlt 20 évben jelentős változások történtek a rehabilitáció
területén. A fekvőbeteg-ellátásban országos igényeket ellátó hálózat, a
speciális feladatok ellátására szakosodott osztályok jöttek létre. Az 1980-as
években még csak közel 1000 ágyon végeztek rehabilitációs tevékenységet,
jelenleg már több mint 6500 rehabilitációs ágy működik az országban. A kezelt
esetek száma 11 384 (1987-es év) volt, amely 2019-ben már 95 693-ra emelkedett.
Rehabilitációs szakvizsgát 552 orvos szerzett a kezdetektől, de rehabilitációs
tevékenység végzéséhez a többi teamtag (ápoló, mozgásterapeuta, ergoterapeuta,
pszichológus, logopédus, szociális munkás) munkája is nélkülözhetetlen. A négy
orvostudományi egyetemen megalakultak a rehabilitációs tanszékek, a graduális és
posztgraduális képzés is összehangoltan történik. A kutatás és az oktatás
központja az országos intézet maradt. A rehabilitációs szakterület fejlődésének,
a kutatásoknak az eredményei Magyarországon rendezett nemzetközi konferenciákon
is bemutatásra kerültek. Orv Hetil. 2023; 164(19): 722–728.
Study on the influence of foreign direct investment on innovations in enterprises in Poland using the ECM model
Authors: Salamaga Marcin
Published: May 2023

In many theories of economics and empirical research, foreign direct investment (FDI) is perceived as a potential technology transfer channel bringing tangible benefits to FDI exporting countries and host countries. In light of some theories, such as Vernon’s product life cycle theory or Dunning’s pull factor theory, and the results of empirical research, the impact of inward FDI flows inhibits the development of innovation or has a neutral effect on innovation in the host country. In the era of the growing internationalisation of enterprises, and the search for opportunities for enterprises to compete on the domestic and foreign markets, innovation is becoming one of the most important elements of building a competitive advantage. Innovation and new technologies are also of fundamental importance for Polish enterprises that want to compete effectively. The question is, to what extent FDI in Poland favours this process, and to what extent limits it? In the empirical studies conducted so far for the Polish economy in the field of the relationship between the inflow of FDI and innovation, there are not many models that would allow to describe the cause-effect relationship between the discussed categories. The authors of this article attempt to fill this research gap. The main goal was to examine the directions and intensity of the impact of foreign direct investment on the level of innovation of enterprises in the main sectors of the economy in Poland. The study used, among others, panel data models with error correction mechanism (ECM) and the Granger causality test. The results confirmed the positive impact of foreign direct investment on the innovativeness of enterprises both in the industrial sector and in the service sector. Moreover, the impact of FDI on the innovativeness of enterprises in the industrial sector turned out to be stronger than the impact on the innovativeness of companies from the service sector.

Business Model Canvas and Entrepreneurs: Dilemmas in Managerial Practice
Authors: Lopes Humberto , Rodrigues Vívian , Leite Ramon , Gosling Marlusa
Published: May 2023

The literature on business models has developed under the assumption that they are tools that managers in general, and entrepreneurs in particular, use intensively to analyze information and make decisions. However, this approach has historically presented little empirical evidence about its relevance. This paper investigates this issue by assessing whether and how entrepreneurs use business models in their everyday practice. We used qualitative analysis of interviews with a group of micro and small entrepreneurs to evaluate their attitude toward one of the best-known business model frameworks on the market, the Business Model Canvas (BMC). The results indicated that these entrepreneurs tended to adopt the BMC if they believed their market was static. In more dynamic markets, they preferred to draw on their practical experience. These results highlight that entrepreneurs’ perception of their firm’s competitive environment is decisive in defining their attitude toward using business models as viable managerial tools.
Homo remotus - Kritik zur Führung auf Distanz
Authors: Karp Markus
Published: May 2023

Wie sich die Welt um uns herum verändert, nehmen wir wohl so wahr, als würde darunter eine Beschleunigungskraft wirken. Die Entwicklung gesellschaftlicher Interaktionen wird von uns Menschen selbst angetrieben. Je mehr sich die eine oder andere Gruppe in eine bestimmte Richtung verhält, umso mehr wirkt das Gruppenverhalten als Entwicklungstendenz. Die technisch vernetzte Welt drängt seit über 20 Jahren in unseren Lebens- und Arbeitsalltag vor. Die fast drei Jahre andauernde Corona- Pandemie hat unter Druck von Kontaktbeschränkungen die Nutzung der technischen Möglichkeiten beschleunigt und damit Arbeitsflexibilität und -mobilität in einer Weise realisiert, wie dies zuvor noch nie der Fall war. Arbeitswelt ist Lebenswelt; und deshalb wirkt sich ein zunehmendes Potenzial an Distanzinteraktionen auf wirtschaftliche, soziale, psychische, rechtliche und/oder kulturelle Bedingungen aus.
A máquina universal: uma análise da mobilização do discurso moral na Folha Universal nas eleições de 2022
Authors: Oliveira Fabrício Roberto Costa , Gracino Junior Paulo
Published: May 2023

Resumo: O objetivo deste artigo é apresentar uma análise sobre a maneira com que a Folha Universal, da Igreja Universal do Reino de Deus (IURD), mobilizou discursos políticos religiosos de fundo moral nas eleições de 2022. Nosso recorte de análise cobrirá o período que se estende da primeira edição do ano até a edição que precede a votação em segundo turno. Nossa pesquisa evidencia que o jornal da IURD foi um órgão politicamente atuante e se colocou como instrumento de campanha do campo conservador e deixou explícito o apoio à candidatura de Jair Bolsonaro. Nosso trabalho revela que a pauta dos costumes alicerçada numa postura conservadora de defesa da “família tradicional” e o receio de um governo de esquerda foram discursos basilares na defesa da candidatura de Bolsonaro e pautaram inclusive suas propostas de governo. Esse cenário contribuiu para que o seu principal adversário, Luiz Inácio Lula da Silva, assumisse compromissos com pautas morais, recuando e/ou abandoando algumas agendas caras aos movimentos sociais historicamente ligados à esquerda e ao Partido dos Trabalhadores.

El animal, ¿es una otredad posible? Indagaciones fenomenológicas a partir de Husserl y Heidegger
Authors: Ayala-Colqui Jesús
Published: May 2023

Resumen: El presente artículo tiene como objetivo analizar el concepto de animalidad desde la perspectiva de Edmund Husserl y Martin Heidegger. Más precisamente se plantea la pregunta de si el animal posee el estatuto de la otredad o carece de él. En efecto, el animal, respecto al humano, resulta un ente otro, pero, desde los supuestos de la fenomenología, ¿eso basta para que este sea aprehendido como una intersubjetividad o una coexistencia que se dona al mundo de los seres humanos? Para responder esta cuestión revisaremos la argumentación de Husserl, especialmente en Hua IV y Hua XXXIX y la de Heidegger en GA 2 y GA 29/30. Finalmente añadiremos una consideración crítica de las ideas de los autores estudiados de cara a los desarrollos de la biología contemporánea para preguntarnos en qué medida su indagación filosófica se condeciría con la evidencia zoológica actual.
‘Who Announces the Nonrecourse?’: The fort/da in ‘To do Justice to Freud’ and in the Derrida/Foucault debate
Authors: Montalva Joaquín
Published: May 2023

Abstract: This article consists of a commentary on Derrida’s essay “To do Justice to Freud: The History of Madness in the Age of Psychoanalysis”, with the aim of tracing what cannot be re-appropriated by the presuppositions of the Derrida/Foucault debate. By analysing the question “who announces the nonrecourse?”, I will explore the way in which Derrida’s writing is affected by the necessity and impossibility of not repressing unreason. I will defend that Derrida compulsively writes the effects of his own resistance to repress unreason by reproducing the Foucauldian quest for a “beyond of reason”. This repetition compulsion not only keeps re-opening the debate, but more importantly, it triggers the return of unreason as a disarrangement of the principles of identity and linear time which destabilizes any authorial ground for a history of madness in general and for any of its critiques. This article will read the exchanges between Derrida and Foucault by deconstructing the premises of any debate in general.
A visão em deus e o primado da representação em Malebranche
Authors: Kontic Sacha Zilber
Published: May 2023

Resumo: O presente artigo visa a examinar a noção de representação presente na exposição malebranchiana da tese da visão das ideias em Deus. Para tanto, volta-se para a progressiva precisão atribuída por Malebranche ao termo ideia, buscando ressaltar o caráter radicalmente representativo do conceito. Em seguida, analisa-se de que modo essa ideia representativa prescinde, na filosofia do oratoriano, de uma correspondência com a existência. Por fim, busca-se mostrar como esse primado da representação se articula com a tese da visão em Deus. Com isso, torna-se possível conceber como essas ideias representativas podem fundar, na filosofia de Malebranche, uma verdadeira ciência.
“I Study When All My Family is Asleep”. Gender, Time and Space in Online Education in the COVID-19 Pandemic,
Authors: González Maria Fernanda , Barbato Silviane Bonaccorsi
Published: May 2023

Abstract The COVID-19 pandemic has radically altered the ways of working, studying, and interacting globally, forcing people and communities to reinterpret their daily activities. This study analyzes the changes experienced by working mothers who began distance studies at an Argentine university during the second year of the pandemic. Results indicated how spaces and time were transformed, and gender inequalities deepened. The pandemic, above all, impacted the positions and negotiations that working mothers managed to establish to continue studying in a virtual university environment. In these cases, conquering time and space for learning is, at the same time, an act of acceptance and innovation as a woman.

Published: May 2023

Abstract The aim of this article is to present evidence of validity for the ‘work-family conflict scale’ with a sample of 10,383 professionals working in Brazilian public security. Cross-validation procedures were applied through the definition of two subsamples, exploratory and confirmatory factor analyses were performed. All ethical procedures were followed. The results found in both the exploratory factor analysis (‘Work Interference with Family’ Factor, with factor loadings between .91 and .81 and alpha of .93, and ‘Family Interference with Work’ Factor, with factor loadings between .96 and .71 and alpha of .90) and the confirmatory analysis (χ2/df <5; CFI >.98; TLI >.98; RMSEA <.10) demonstrate robust evidence of validity, indicating the use of the scale in other organizational contexts.
The effect of Phytosphingosine and bioactive glass-ceramics in preventing dental enamel erosion

Published: May 2023

Abstract This study evaluated the effect of phytosphingosine (PHS) and bioactive glass-ceramic (Biosilicate) on dental enamel in terms of color alteration (ΔE), microhardness, and surface roughness when submitted to erosive challenge (EC). Sixty specimens of bovine teeth (6×6×2mm) were obtained. Initial color (Easyshade, VITA), KHN (HMV-2, Shimadzu), and Ra (SJ-201P, Mitutoyo) measurements were performed. Specimens were separated into groups according to treatments: PHS, 10% Biosilicate, PHS+10% Biosilicate, and artificial saliva (control) and submitted to EC with Coca-Cola for 2 min. This cycle was repeated 4 times daily/15 days. Between cycles, specimens remained in artificial saliva (2 h/37°C). After daily cycles, they were also stored in artificial saliva at 37ºC. Final color, microhardness, and surface roughness measurements were done. Color and KHN data were analyzed by one-way ANOVA, Tukey’s test; and Ra, by 2-way ANOVA, repeated measures, and Tukey’s test (p<.05). The highest ΔE occurred in Saliva+EC (p<.05). Groups treated with PHS presented lower color change than Saliva+EC (p<.05). All the groups presented mean values above the 50:50% perceptibility (50:50%PT) and acceptability (50:50%AT) thresholds, except for control that showed mean value above 50:50%PT but below 50:50%AT. Biosilicate+EC showed higher relative microhardness than Saliva+EC (p<.05), but was similar to PHS+EC and PHS+Biosilicate+EC. Final enamel surface roughness increased for all the groups (p<.05), except for the control. The Biosilicate may prevent enamel mineral loss induced by erosion better than saliva. The PHS associated or not to Biosilicate demonstrated better color stability than saliva.
Does the initial surface roughness of different CuNiTi wires affect the frictional resistance?
Authors: Pentagna Bernardo Brenner , Degan Viviane Veroni , Godoi Ana Paula Terossi de , Correr Américo Bortolazzo , Correr Ana Rosa Costa , Menezes Carolina Carmo de
Published: May 2023

Abstract This study aimed to assess and correlate initial surface roughness and frictional resistance of rectangular CuNiTi wires inserted in different self-ligating brackets. The sample consisted of 40 bracket-wire sets (rectangular CuNiTi wires of 0.017" x 0.025" and passive self-ligating brackets) divided into four groups (n=10): metallic self-ligating bracket and metallic CuNiTi wire (G1); metallic self-ligating bracket and rhodium-coated CuNiTi wire (G2); esthetic self-ligating bracket and metallic wire (G3); esthetic self-ligating bracket and rhodium-coated CuNiTi wire (G4). The initial surface roughness of the wires was examined with a Surfcorder roughness meter, model SE1700. Later, frictional resistance was assessed in an Instron 4411 universal testing machine at a speed of 5 mm/min, in an aqueous medium at 35°C. Microscopic analyses of surface morphology were performed with scanning electron microscopy, using an LEO 1430, with magnifications of 1000X. Generalized linear models were applied, considering the 2 x 2 factorial (bracket type x wire type), at a 5% significance level. Regardless of bracket type, the groups with esthetic wires presented higher initial surface roughness than the groups with metallic wires (p<0.05). There was no significant difference between the different bracket-wire sets for frictional resistance and no significant correlation between frictional resistance and initial surface roughness in the environment studied. It is concluded that esthetic wires presented higher initial surface roughness but did not interfere with the frictional resistance between brackets and wires.

Abstract The present study evaluated the actual rotational speed of three different endodontic motors compared to the values provided by the manufacturers. A total of three endodontic motors (X-Smart Plus, VDW.Silver, and iRoot) were tested at 400 rpm and 800 rpm and 2 N/cm2 torque. The kinematics of the devices was recorded by using a custom angle-measuring disc with a 50-mm diameter attached to the handpiece provided by the manufacturer, whereas their movement was captured by a high-speed camera at 2,400 frames per second, 800 x 800 pixel-resolution and distance of 0.3 m from the target object. Statistical analysis was performed at a significance level of 5%. At 400 rpm, the iRoot motor had a value of 17.94 rpm above that indicated by the manufacturer, which was significantly different from those of X-Smart Plus (5.20 rpm below that indicated by the manufacturer) and VDW.Silver (0.62 rpm above that indicated by the manufacturer) motors (P < 0.05). At 800 rpm, the iRoot motor had a value of 51.34 rpm below that indicated by the manufacturer, whereas the X-Smart Plus motor had a value of 13.00 rpm below that indicated by the manufacturer (P > 0.05). The VDW.Silver motor statistically differed from the iRoot and X-Smart Plus ones, showing a value of 1.68 rpm above that indicated by the manufacturer. In conclusion, the X-Smart Plus, VDW.Silver, and iRoot motors showed lower variations in the rotational speed values compared to those reported by their manufacturers. The endodontic motors presented different behaviors between them, with the VDW.Silver motor presents the most accurate values and the iRoot presents the most divergent values.

Abstract This study aimed to detect, quantify and compare the immunohistochemical expression of EGFR and VEGF and microvessel count (MVC) in oral lipomas, and to correlate the findings with clinical and morphological characteristics of the cases studied. The sample consisted of 54 oral lipomas (33 classic and 21 non-classic) and 23 normal adipose tissue specimens. Cytoplasmic and/or nuclear immunohistochemical staining of EGFR and VEGF was analyzed. The angiogenic index was determined by MVC. Cells were counted using the Image J® software. The Statistical Package for the Social Sciences was used for data analysis, adopting a level of significance of 5% for all statistical tests. A statistically significant difference in EGFR immunoexpression (p=0.047), especially, between classic lipomas and normal adipose tissue. There was a significant difference in MVC between non-classic lipomas and normal adipose tissue (p=0.022). In non-classic lipomas, only VEGF immunoexpression showed a significant moderate positive correlation (r=0.607, p=0.01) with MVC. In classic lipomas, the number of EGFR-immunostained adipocytes was directly proportional to the number of VEGF-positive cells, demonstrating a significant moderate positive correlation (r=0.566, p=0.005). The results suggest that EGFR, VEGF, and angiogenesis participate in the development of oral lipomas but are not primarily involved in the growth of these tumors.

Published: May 2023

Abstract The present study aims to evaluate the effect of different glide path instruments on the cyclic fatigue resistance of reciprocating endodontic instruments after three uses in mandibular molars. Eighteen Wave One Gold Primary reciprocating instruments were selected and randomly divided into three groups according to the glide path instrument: G1 - manual file K #15, G2 - Wave One Glider reciprocating instrument, and G3 (control group) - glide path was not performed. The reciprocating instruments were tested on mandibular molars and subdivided into three other groups: a new instrument, an instrument with a previous single-use, and an instrument with two previous uses. After the endodontic instrumentation, the instruments were subjected to the cyclic fatigue resistance test using an appropriate tool. The data were submitted to the Shapiro-Wilk test, and subsequently the Kruskal-Wallis test with a significance level of 5%. The results showed no statistical difference between the groups. Thus, it was concluded that the creation of a glide path did not affect the cyclic fatigue resistance of the reciprocating instrument. In addition, the reuse of final preparation instruments up to two times proved to be safe since no fractures were observed in the tested instruments.

Abstract This study aimed to compare the survival of replanted teeth that followed the 2012 or the 2020 International Association of Dental Traumatology (IADT) guidelines. Sixty-two permanent replanted teeth were retrospectively assessed (IADT 2012, n = 45; IADT 2020, n = 17). Five years after replantation (from January 2017 to December 2021), clinical and radiographic examinations were performed. A significance level of 95% was considered to evaluate the outcomes. Thirty-one teeth (50.0%) remained in their sockets and 31 (50.0%) were lost due to external root resorption. Of the 25 (40.3%) teeth replanted within one hour, 16 (64.0%) remained in their sockets, and 9 (36.0%) were lost. Twenty-two (71.0%) of all 31 lost teeth had an extra-alveolar time of more than one hour. Twelve teeth remained in their sockets without resorption: 8 (66.7%) were replanted within one hour, 2 (16.7%) followed the 2012 IADT, and 2 (16.7%) the 2020 IADT guidelines for late replantation. There was a significant difference (p <0.05) in the extra-alveolar time (< one hour), but without difference between the guidelines in late replantation (p > 0.05). Replanted teeth following both, 2012 or 2020 IADT guidelines, have similar clinical outcomes. The extra-alveolar time of less than one hour was demonstrated to be important to keep the permanent tooth in its socket.

ABSTRACT: Spermatozoa experience oxidative, osmotic, chemical, and thermal stresses when cooled, which degrade the quality and fertilizing capacity of the cells. Adding antioxidants to the sperm extender mitigates these alterations. This study evaluated the effect of isoespintanol (ISO) on boar semen subjected to cooling. Fifteen ejaculates from five boars (Susscrofadomestica) were extended in Beltsville thawing solution (BTS) supplemented with 0 µM (control), 5 µM (ISO5), 10 µM (ISO10), 15 µM (ISO15), 20 µM (ISO20), 25 µM (ISO25), and 30 µM (ISO30) of ISO, which were then cooled for five days at 16 °C. Sperm kinetics, total motility (TM), and progressive motility (PM) were evaluated every 24 h using an IVOS computer-assisted sperm analysis (CASA) system. On day 1 and day 5 of cooling, a hypoosmotic test, spectrofluorometry, and flow cytometry were performed to evaluate the following: membrane functionality, measured as a function of hypoosmotic swelling (HOS); total antioxidant capacity (TAC); reactive oxygen species (ROS); and mitochondrial membrane potential (Δ¥M). Regression analysis and comparison of means using the Duncan test were performed. The ISO added had a slight impact on sperm motility, as evidenced by a reduction in TM at 24 h of cooling (but not prior) with the addition of 20 µM of ISO. Similarly, no effect of the ISO on the kinetics and functional integrity of the sperm membrane was observed at 96 h of cooling; however, the regression coefficients indicated that the ISO lowered the rate of decrease in sperm motility and the proportion of rapid spermatozoa relative to the concentration of ISO used. The ISO did not affect the TAC of the cooled semen; however, different concentrations of ISO lowered ROS production in the semen after 96 h of cooling. ISO also impacted the Δ¥M of the spermatozoa at 0 h of cooling, increasing the proportion of low Δ¥M cells and decreasing the proportion of high Δ¥M cells. In conclusion, ISO can reduce the loss of quality and oxidative stress occurring in boar semen during cooling and can modulate the mitochondrial activity of sperm.

Objetivo: analisar o perfil de enfermeiras(os) acerca das práticas integrativas e complementares em saúde e compreender como são utilizadas no cuidado às pessoas com hipertensão arterial. Método: explanatório sequencial misto. A etapa quantitativa transversal contou com 386 enfermeiras(os), via questionário virtual, abordando perfil sociodemográfico e profissional, formação e atuação, com análise descritiva e inferencial. A etapa qualitativa ocorreu mediante 18 entrevistas virtuais com profissionais que possuem formação nas práticas e as utilizam no cuidado às pessoas com hipertensão, fundamentada na análise participativa. A integração se deu por conexão. Resultados: 36,8% tinham formação nas práticas, predominando mulheres, brancas, casadas, servidoras públicas, com média de idade de 37 anos (+ 9,4). 14,2% utilizam as práticas no cuidado às pessoas com hipertensão, predominando a auriculoterapia (28,2%) e a sangria na crise hipertensiva. Evidenciou-se a abordagem integral do paciente, não limitada ao sinal vital alterado, com intervenção na ansiedade, estresse, sono e repouso. Como potencialidade, tem-se o auxílio na adesão ao tratamento. Conclusão: apresentou-se o perfil de enfermeiras(os) com formação em práticas integrativas e complementares. Compreende-se que tais práticas têm implicação na diminuição da pressão arterial, e são utilizadas no cuidado às pessoas com hipertensão, porém de forma incipiente, considerando o potencial no cuidado de enfermagem.

Objective: to verify the implications of practical activities in the Skills and Simulation Laboratory on the motivation and feelings expressed by undergraduate students when returning to face-to-face activities after the social isolation caused by COVID-19 pandemic. Method: a quasi-experimental study, with a single group and of the pre- and post-test type, carried out through an educational intervention based on skills training on medication administration and venipuncture, with medical students from a Brazilian public university. The sample was comprised by 47 students. The instruments of students’ characterization and self-perceived feelings and the Situational Motivation Scale were used for data collection. Results: in the sample, 98% mentioned the lack of practical activities during the pandemic. The most frequently described feeling was anxiety. After carrying out the activity, there was a change in the frequency of expressed feelings, although there was no significant change in motivational levels. External Regulation (5.1 - 5.6), Identified Regulation (6.1 - 6.4) and Intrinsic Motivation (5.6 - 6.0) presented high results, showing similarity to the feelings reported by the learners. Conclusion: motivation is essential for effective learning and the use of active methodologies reinforces skills built in an affective way in the students facing the learning process.
