Published: July 2021

Documenting patterns of spatio-temporal change in hyper-diverse
communities remains a challenge for tropical ecology, yet is
increasingly urgent as some long-term studies have shown major declines
in bird communities even in relatively undisturbed sites. In 1982,
Terborgh et al. quantified the structure and organization of the bird
community in a 97-ha. plot in southeastern Peru. We revisited the same
plot in 2018 and repeated the same intense combination of methodologies
as the original study in order to evaluate community-wide changes.
Contrary to the results from studies elsewhere, we found little change
in bird distribution and abundance within the plot, although there were
some declines related to loss of mixed-species flocks with a high level
of species interdependence. This apparent stability suggests that
large-scale forest reserves such as Manu National Park may provide the
conditions necessary for establishing refugia from at least some of the
effects of global change on birds.
Covid 19 - Acing the Treatment
Authors: Hunter Jez , Bura Puskar , King Richard , Thomson George
Published: July 2021

ACE 2 is the functional receptor that SARS-Cov-2 virus requires to enter
cells and cause dysregulated inflammatory conditions that contribute
towards acute lung injuries. The RAAS with its physiological
surveillance and regulation system can be implicated in both harm and
therapeutic benefit. The initial observational studies suggesting the
discontinuation of ACE-I and ARBs have been firmly rebutted by
international societies. On the contrary, these therapeutics may confer
a survival benefit in Covid 19 infections. Understanding the biological
plausibility of this pathway alongside the emerging therapeutic evidence
may yield new modes of treatment. Such developments appear fundamentally
important in the battle against the inevitable emergence of new variants
and their potential to drive future waves of Covid 19 pandemics.
Statut vert des espèces de l’UICN
Authors:   IUCN, International Union for Conservation of Nature
Published: July 2021

Le déclin de nombreuses espèces en voie d’extinction a largement orienté les efforts de conservation de manière à ce que ces espèces continuent d’exister. Toutefois, les conservationnistes reconnaissent depuis longtemps la nécessité de compléter ces efforts par des mesures de reconstitution des populations en déclin dans l’ensemble de l’aire de répartition d’une espèce, et de restauration des espèces dans les écosystèmes où elles ont disparu. Le Statut vert des espèces de l’UICN comprend cinq objectifs principaux : fournir un cadre normalisé pour mesurer le rétablissement des espèces ; reconnaître les réalisations en matière de conservation ; mettre en évidence les espèces dont le statut de conservation actuel dépend de la poursuite des actions de conservation ; prévoir l’impact attendu des actions de conservation planifiées ; et relever les niveaux d’ambition pour le rétablissement des espèces à long terme.
The Effect of Market Transparency on Corporate Disclosure: Evidence from the Observability of Bond Prices and Trading
Authors: Rickmann Georg A.
Published: July 2021

Market prices and trading are important information constructs that reveal information to market participants. I study how the observability of market prices and trading (hereafter, market transparency) affects firms' disclosure incentives. I exploit the staggered introduction of TRACE, which made bond prices and transactions publicly observable. I find that firms provide more guidance when their bonds' prices/trading become observable, suggesting that investors' access to market information limits managers' incentives to withhold information. This effect is stronger for firms whose revealed prices contain more new information, and it is more pronounced for the disclosure of bad news. I corroborate my results using (1) a controlled experiment, in which prices/trading were revealed for randomly selected bonds, and also (2) relevant threshold rules. Together, my results suggest that increased market transparency improves investors' access to information not only directly, by revealing the information contained in returns/trading, but also indirectly, by increasing corporate disclosure.

Authors:   Lviv Polytechnic National University, Skasko O.
Published: July 2021

Modern theoretical and applied principles of digitalization and its impact on the information security of enterprises are revealed. The main digital trends that determine the directions of development of accounting and financial reporting. Peculiarities of the Ukrainian economic environment and possibilities of introduction of the means of informatization developed in the world theory are analyzed. The mechanisms of large-format automation of financial reporting processes and the use of document flow in the activities of Ukrainian enterprises are studied. The hypothesis of this study is the assumption of the positive impact of digital technologies in the reporting of socially significant Ukrainian enterprises. The study used general and specific research methods, namely: the method of systematic analysis of domestic and foreign experience in the digital economy to justify a systematic approach to the study of phenomena and processes of building a new paradigm of interaction of economic agents; dialectical method for studying the genesis of the digital economy as a defining trend of modern global socio-economic development; method of induction to determine the factors influencing the environment of digitization of accounting information; the grouping method provided systematization of factors influencing the development of digitization processes, etc. It is substantiated that digitalization as an environment for economic processes and operations will lead to changes in methodological tools of accounting and virtualization of accounting processes.

The purpose of the article is to identify the main problems in the basic and advanced training of civil servants. Using a retrospective review and taking into account the current situation, develop a strategic plan for further action to improve the system of training of civil servants. Outline priority areas and forms of advanced training of existing staff and basic training of new civil servants to meet the needs of highly qualified and competitive staff. In this article, the authors used the literature review method and analytical method to develop a strategic plan for further action to improve the training of civil servants. Based on these two methods, the priority areas and forms of advanced training of existing staff and basic training of new civil servants were outlined. It is established that the existing system of advanced training and basic training of civil servants still needs to be improved without moving towards the reforms carried out by the National Agency for Civil Service Affairs of Ukraine. The main attention in the basic training should be paid to the practical application of the acquired knowledge. The most effective for full-time students will be the internship of study in public authorities lasting 1 week of each semester. In this case, the topic of internship should correspond mainly to the three subjects studied, and it should take place at the end of the semester as a result before the exam or test. The results of the internship must be evaluated at least 20% of the total grade for the subject. Part-time students are invited to take an internship before the session. Civil service advanced training is encouraged to take place annually in order to be competitive in times of rapid change. Thus the direction of advanced training is recommended to choose independently and to coordinate with the direct head. The number of hours per year must be at least 7 ECTS credits (210 hours), as 1 ECTS credit is insufficient for the effective acquisition of new knowledge. The results of this research can be implemented in the educational process to meet the needs of highly qualified and competitive staff, namely civil servants of the new generation. Also, the findings may be of interest to the leadership of the National Agency for Civil Service Affairs of Ukraine for further effective civil service reform in Ukraine. This article highlights the main problems of today, developed a strategic plan for further improvement of the existing system of training and retraining of civil servants. This will help to take effective steps towards the existing problems and move in the right direction of further reforms, and thus speed up progress towards the EU.
Organizational changes in the activity of enterprises in the context of urgent crisis management

Published: July 2021

Eliminating or reducing the negative impact of crisis phenomena on the economic condition of an enterprise and ensuring its further effective development is closely related to the concept of organizational changes. On the one hand, urgent crisis management tools almost always cause such changes. On the other hand, crisis phenomena in the activities of a business entity lead to the need to introduce organizational changes. In this context, it is noted that it is important to diagnose such changes even before their practical implementation begins. This problem is especially relevant when it is necessary to introduce so-called large-scale changes in the context of crisis management. Any mistakes at the beginning most likely will lead to failure to achieve the set goals and to problems in the practical implementation of these changes. Consequently, based on the results of the conducted research, organizational changes in the activities of enterprises in the conditions of crisis management at the beginning are proposed to be diagnosed taking into account four areas that correspond to the PAEI-model of Adizes, well known in the theory and practice. At the same time, it provides for determining the market orientation of organizational changes (proactive nature of organizational changes); the social orientation of organizational changes (integrative nature of organizational changes); the impact of organizational changes on the enterprise administration system (complementary nature of organizational changes); the impact of organizational changes on the operating environment of the enterprise (functional nature of organizational changes). The article offers a method for diagnosing organizational changes in the activities of enterprises in the conditions of crisis management, based on the method of hierarchy analysis (Analytic Hierarchy Process – AHP) and provides for the implementation of such key stages: the formation of an expert group; determining the level of a hierarchical model for diagnosing organizational changes in the conditions of anti-crisis management; studying the essence and characteristics of the proposed organizational changes, so that then diagnose them taking into account the directions of proactive, integrative, functional and complementary nature, using matrices of pairwise comparisons; determining eigenvectors, as well as establishing their normalized values, applying the known geometric mean of the matrix lines; determining the consistency of expert opinions; forming conclusions and recommendations. The possibility of practical use of the proposed method of diagnosing organizational changes in the activities of enterprises in the context of crisis management is confirmed by relevant calculations on the example of several business entities in the Lviv region.

NATIONAL INSTITUTIONS ESTABLISHED IN ACCORDANCE WITH THE PARIS PRINCIPLES, ENGAGED INTO THE PROMOTION AND PROTECTION OF HUMAN RIGHTS IN THE SYSTEM OF INTERNAL MEANS OF SECURITY
Authors: Deshko Lyudmyla
Published: July 2021

The purpose of the article is to clarify the place of national institutions engaged in the promotion and protection of human rights in the system of domestic means created in accordance with the Paris Principles. Research methods is the general methods of scientific cognitivism as well as concerning those used in legal science: methods of analysis and synthesis, formal logic, comparative law etc.

The concept of understanding of the organizational and legal guarantees of human and citizen's rights has been improved in the constitutional law science, namely: the classification criterion for division into groups is the possibility/non possibility of exercising any kind of state coercion in the course of jurisdictional/ non jurisdictional activity; representative body (body responsible for ensuring Ukraine's representation in the European Court of Human Rights and coordinating the implementation of its decisions), bodies of the state executive service, private executors are the elements of the system of organizational and legal guarantees of human and citizen's rights; by classification criterion – the protection of human rights and fundamental freedoms is the primary function of the authority-guarantor or similar body of some other kinds of functions – it is substantiated that national institutions engaged into the promotion and protection of human rights belong to the group of authority-guarantor of special competence established specifically to provide guarantees, human rights and fundamental freedoms.

It is proposed within the group of authority-guarantor of special competence established specifically to ensure the guarantees of human rights and fundamental freedoms, to distinguish a sub-group of national institutions engaged into the promotion and protection of human rights: 1) human rights commissions; 2) human rights ombudsmen; 3) anti-discrimination ombudsmen (commissions); 4) human rights institutes (centers); 5) human rights advisory committees; 6) comprehensive human rights institutes.
INFORMATION PRIVACY: A CONCEPTUAL APPROACH
Authors: Serohin Vitalii
Published: July 2021

The paper attempts to expose the basic concepts of informational privacy reflected in Western jurisprudence, as well as to outline the author's vision of the content and scope of informational privacy, to distinguish the relevant powers from which this right consists, to reveal its place and role from the standpoint of system-structural approach.

It is noted that in the modern scientific literature, dedicated to ensuring the privacy and respect for his / her privacy, clearly distinguishes two main approaches to understanding the informational advantage - broad and narrow. Proponents of the narrow approach consider the primes solely in the informational aspect, and other constituents (physical, visual, phonetic privacy, etc.) tend to relate to the content of other fundamental rights. However, one group of authors interprets information privacy as the right of the person to control their personal data, while the second group considers it more rational and efficient to consider information pricing as the right of ownership of personal data. Attempting to unite both camps of supporters of a narrow interpretation of the information front is the Restricted Access / Limited Control (RALC) theory.

Proponents of the broad-based approach view information primacy as important, but only one of the many substantive elements of constitutional law in favor. At the same time, the authors' exit beyond the information sphere when considering the content of the precedence can be considered progressive and more consistent with the essence of this right and its purpose in ensuring personal freedom and autonomy.

In view of the author, revealing the content of the right to privacy, it should be borne in mind that the object of this right includes several areas (aspects), in each of which a person may be in different states of privacy, and the privacy itself has certain measurements. On this basis, information is regarded by the author as an element of the constitutional right of privacy, distinguished by the aspects of privacy and the form (method) of its objectification.

Unlike other aspects of privacy, the informational aspect is detached from the physical body of the individual and exists independently, and relevant information continues to exist even after the death of the individual. Therefore, even the death of a person does not make sense of the information associated with that person, and sometimes even enhances its value and significance. It is noted that unlike other aspects of the case, information privacy has no states (such as loneliness, intimacy, anonymity, etc.); it merely provides information protection for such states and does not allow them to be disclosed without the consent of the entity itself.
UKRAINIAN MUNICIPAL REFORM: CONSTITUTIONAL BASIS
Authors: Мішина Наталія
Published: July 2021

The purpose of the article is a teleological and formal analysis of the related to municipal reform constitutional-conceptual documents approved by public authorities. This topic is relevant to the contemporary urgent constitutional problems, because at the beginning of 2020 President of Ukraine announced his plans to initiate changes to the Constitution 1996 about the local government.

The main methods of the research include classical legal science methods. The author uses formal analysis, synthase, inductive and deductive approach to the problems, covered by the article. While looking at the text of Ukrainian Basic Law 1996 and other documents, the author uses the most common methods of legal interpretation (original intention method, purposivism and other).

Results. The author analyzes the constitutional basis of the ongoing Ukrainian municipal reform, that was launched in 1998. Since that time, the Head of the Ukrainian state (President), the Parliament of Ukraine (Verkhovna Rada of Ukraine) and the Government of Ukraine (Cabinet of Ministers of Ukraine) participated in the regulation of this reform. Their actions can’t be characterized as concerted, that is why the biggest part of the documents aim the same results (efficient local self-government according to the European municipal standard and best foreign practices). But the ways of reaching this result differs a lot – it might be revision of the administrative-territorial division, it might be decentralization of the public power, it might be deconcentrating of the local self-government bodies’ competence.

Conclusion. The author recommends, firstly, to revise the concepts of the local self-government reform in Ukraine – as some of the documents, that are really out-of-the-date, should be cancelled. Secondly, all of the existed documents should be analyzed, and in case if there is some interesting and perspective proposal – it can be included to the last version of the Municipal Reform Concept. Thirdly, like the last Concept, they should include not only actions, but actions accompanied by the timeline.
Controlling a Direct Matrix Frequency Converter of Secondary Power Supply Sources for Autonomous Objects

A version of using "sliding modes" in performing discontinuous control of dynamic objects for matrix frequency converters (MFC) as part of an on-board aircraft network is proposed. Unlike the way used in the existing MFC control algorithms, the sinusoidal voltages available in the primary network are processed according to the proposed modernized technology of "sliding modes". The level of discontinuous voltages is selected from the condition of minimum deviations from the target, which has a favorable effect on the spectrum of output voltages. On the selected time interval, the input primary network phase voltages and the specified output network phase voltages are sampled. A positive minimum difference between the primary network phase voltage closest to its desired value and the specified secondary network phase voltage is produced. This difference acts as a positive discontinuous control. A negative difference acts as a negative discontinuous control. Over the calculated interval, the average deviation from the specified phase voltage is zero. Owing to this feature, the smallest distortions in the MFC output voltage spectrum are obtained at arbitrary loads and evolutions of the primary network voltage frequency and amplitude. Versions of three-phase and six-phase primary sources are considered. The effectiveness of the proposed version of using "sliding modes" has been confirmed by simulation.

Dynamics of the Level Formation of Style Hierarchy in Musical Art
Authors: Kapliyenko-Iliuk Yuliya
Published: July 2021

"Style, as a category of musicology, has been studied by scholars of different times. It has a wide range of questions under inquire. The problems of forming a system of style levels have repeatedly been the subject of scientific research. The article is devoted to the study of scientific information sources that consider the principles of style hierarchy, individual, national levels, and their importance in higher systems – the style of genres and eras. Based on research of scholars’ opinions in the field of music style, conclusions about features of hierarchy of style levels, dynamics of their formation are made. Individual style is dominant in the formation of other style levels, in particular styles of genres and era. At the heart of the problem of the individual style study is the personality of the composer with the characteristic features of individual oeuvre. The national style is formed based on social factors, professional national creativity, and folk traditions. The national style manifests the features of the historical category, therefore over time it acquires new characteristic features. Epochal style is a complex coexistence of national music cultures; it subordinates the styles of genres. Thus, the study of the category of style, its theoretical problems, in particular the dynamics of the formation of style levels, demonstrates the timeliness and the need for further exploration.

"This paper represents a more detailed research of one of the defining stylistic aspects for equal voices choral creation composed by Dan Voiculescu. The composer managed to enrich the children's repertoire with important works, starting from the premise that it must be close to the contemporary musical language. Polyphony, in its various forms, gives this type of repertoire stylistic unity and offers many possibilities for modernizing the choral language. Dan Voiculescu uses poliphony to exploit and materialize it in a multitude of compositional devices. The most used polyphonic process in Voiculescu's choral creation is imitative polyphony. It is materialized in various forms, being connected mainly by the tradition of its application from ancient times (Renaissance, Baroque) to the present day.

Stylistics of Impressionism in the Song Cycles of Lesia Dychko “Pastels” and “Enharmonic” on the Poems by Pavlo Tychyna
Authors: Pysmenna Oksana , Myshko Svitlana , Cherevko Kateryna
Published: July 2021

"The aim of the work is to determine the influence of the characteristic features of the linguistic and style environment of the second half of the twentieth century on the development of Lesia Dychko's creative personality (on the example of the song cycles Pastels and Enharmonic, written to the words of P. Tychyna). The analyzed song cycles demonstrate the artist’s deep penetration into the figurative concept of the poet's free verses, reflecting its semantic properties by musical means. We notice a lot in common and consonant in the works of both artists, namely, an impressionistic vision and perception of the surrounding world, a deep philosophical understanding of nature, a symbolic load of images. The musical-theoretical analysis of the cycles has shown the principles of the development of material common to poetry and music, such as cross-cutting development, leitmotif, etc. The article reveals another facet of the composer's stylistic direction, namely, the expressive means inherent in impressionism: the coloristic function of harmony, ostinato techniques and organ points, the melodic line of recitative-declamatory or instrumental plan. The overwhelming majority of them correspond to the principles of impressionism in combination with modern innovative techniques of the musical language and personal individual stylistic features of the composer.

The Dehiscence of Temporalities Between “{In}-flesh-ization” and “Holding[s]-still” Phenomenon in Musicalized Mournfulness
Authors: Bischin Maria Roxana
Published: July 2021

"Long times being left in a penumbra, the violinist Joseph Achron needs a revaluation from the part of phenomenological aesthetic and musicology fields. Following the basic theory of Maurice Merleau– Ponty’s flesh, and few perspectives from Edmund Husserl’s, we demonstrate that insisting on the idea of the inverted plenitude as dehiscence will take us to another level of the perception of the Beauty in ‘Hebrew Melody’, composed by Joseph Achron. The final part of the paper offers to the listener the real possibility to see Beauty’s ingrown/incarnation in the mournfulness “as-it-is” – in its dehiscential plenitude. The purpose of music must also be to bring us closer to the sufferer’s interior structures, but so that we can see the Beauty that lies in it. To achieve this, more ontic openings are needed, and this phenomenon well-characterized by the term dehiscential. ‘Hebrew Melody, Op. 33’– encompasses a whole world. In sound, pain can be exposed much more easily and much more cleansed of its negative aspects. Sonorous mournfulness is different from mournfulness-in-itself, but similar. At the level of human suffering, the two have the same ontic place. When they are filtered through artistic catharsis or artistic judgments, they receive a sublimated note that cuts the thresholds of the common world. The sounds that break the silence of the Being (in its successive openings), are the sounds that crumble the most, are those that scream so soft, so fragile, but scream. This is what we experience with ‘Hebrew Melody, Op.33’. The touching of the impossible things, the nostalgia for the lost memories, the desire to feel a piece of quietness, the sadness of not being happy, like a ship gone towards the blue horizon, the nothingness lived in a mourn – all these penumbrae of a sad soul which may have lost everything shape in us a beautiful Hebrew canvas, the necessity of a never-ending return to the Hebrew village, its synagogue, and life.

Los mapas, como medio de representación gráfica, muestran lo que se quiere ver de la ciudad, como esquemas que visibilizan estructuras urbanas integradas, pero que a su vez ocultan otras. La exclusión –desde un punto de vista territorial– pasa desapercibida por las dinámicas sociales, por lo que recuperar el topos se convierte en algo fundamental. Este artículo propone una nueva esquematización en torno a la exclusión, a través del desarrollo del concepto de exclusión espacial, el cual permite identificar los diversos procesos espaciales que producen exclusión. Así, en la ciudad existen múltiples fuerzas que no son identificadas, por lo que la esquematización de la exclusión espacial se convierte en una alternativa de graficación para visibilizar las fuerzas que interactúan en el ambiente construido. Lo anterior plantea nuevas posibilidades de abordaje para los fenómenos espaciales de las ciudades contemporáneas.
diseño como estrategia de circularidad en el aprovechamiento de residuos agroindustriales
Authors: Buraglia Osorio Mariana
Published: July 2021

Las políticas de implementación de economía circular en Colombia han priorizado el aprovechamiento de recursos de la agroindustria como oportunidad para dar valor a los residuos orgánicos no aprovechados. En este escenario, el proyecto marco que da lugar a este artículo explora, a través de estrategias de ecodiseño, economía circular y diseño guiado por el material (Material Driven Design), las oportunidades de creación y aplicación de materiales biocompuestos, donde el diseño como actividad profesional se visualiza como una estrategia competitiva para el aprovechamiento de residuos agroindustriales y el cierre de brechas tecnológicas en aplicaciones productivas de mediana escala. Este artículo de investigación presenta entonces, un análisis comparativo cualitativo de tres casos de estudio, que permite evidenciar cómo la integración de esa mirada entre lo técnico y lo experiencial realza las potencialidades de aplicación y transformación en contexto de los materiales aquí expuestos, que lograron una estabilidad material suficiente para su transformación y uso, su propio balance entre lo sensorial y estético, de bajo impacto ambiental, y con procesos de conformación y producción viables y escalables basados en procesos low tech de fácil transferencia tecnológica.

Introducción: Las fracturas del fémur proximal, también llamadas fracturas de cadera, se encuentran entre las principales causas de morbilidad en el mundo donde la población más afectada son los adultos. Esto afecta en gran medida a la salud pública debido a su alto costo socio-económico y la incapacidad laboral que genera. Objetivo: Determinar la epidemiología de fractura de cadera en el adulto atendido en un hospital de tercer nivel de Cúcuta, Norte de Santander, Colombia. Materiales y métodos: Un estudio descriptivo, transversal, de análisis retrospectivo, con enfoque cuantitativo. Se tomaron 175 pacientes con fractura de cadera, que cumplían con los criterios de inclusión, con una población diana de mayores de 50 años de edad. Adicionalmente de las variables que se registraron: Edad, género, causa, comorbilidad, clasificación, intervalo de cirugía, tipo de intervención quirúrgica. Resultados: De los 175 pacientes se encontró una edad media general de 75.35 años, el 60% corresponde a pacientes de sexo femenino, la causa más común son los factores extrínsecos, la mayoría de pacientes no padecía ninguna enfermedad, en mayor relevancia acudían por una fractura intertrocanterica. El 50% de los pacientes son intervenidos quirúrgicamente en un periodo de tiempo superior a los 4 días. Conclusiones: A partir de los hallazgos encontrados, se acepta que la frecuencia de fractura de cadera se encuentra asociada a diversas variables las cuales fueron analizadas en este estudio obteniendo resultados novedosos que quedan a disposición de la academia en bienestar de la salud, impulsando nuevos estudios.
Effekte schulischer Berufswahlaktivitäten auf die berufliche Selbstwirksamkeit von Jugendlichen beim Übergang in die berufliche Grundbildung
Authors: Neuenschwander Markus P. , Jan Hofmann
Published: July 2021

Lehrpersonen können den Übergang in die berufliche Grundbildung von Jugendlichen im Rahmen von unterrichtsinternen Aktivitäten, unterrichtsexternen Aktivitäten und Coaching unterstützen. Ein Analysemodell wurde anhand einer Längsschnittstichprobe mit 1171 Jugendlichen überprüft (Befragung im 9. Schuljahr und im ersten Jahr der beruflichen Grundbildung). Ergebnisse von Strukturgleichungsmodellen zeigen, dass unterrichtsinterne Aktivitäten die berufliche Selbstwirksamkeit vor dem Übergang, das Vorwissen über den Lehrbetrieb und indirekt die berufliche Selbstwirksamkeit nach dem Übergang vorhersagen. Die Daten liefern Hinweise zu einem empirisch gestützten Modell der schulischen Unterstützung beim Übergang in die berufliche Grundbildung.
Le chemin de l’école : un tiers-lieu vecteur d’apprentissages pour les enfants ?
Authors: Camponovo Sara , Moody Zoe
Published: July 2021

Les études de l’enfance (Childhood Studies) montrent que les enfants n’apprennent pas seulement au travers d’une éducation formelle ou non formelle, soit au sein de l’école ou au sein du foyer familial. Ils et elles apprennent également dans d’autres milieux et contextes au travers de leurs propres actions. Sur la base de données empiriques issues d’un projet de recherche inter- et transdisciplinaire sur le chemin de l’école, cet article met en lumière et questionne les apprentissages informels réalisés par les enfants dans cet espace. Premièrement, il montre comment le chemin de l’école permet aussi bien de se préparer et inversement de se distancier des rôles attendus à l’école et à la maison. Deuxièmement, une analyse des types d’apprentissages que font les enfants le long du chemin de l’école et complémentaires à ceux réalisés dans les sphères familiale et scolaire, est effectuée.

Aim

To compare the degree of platelet inhibition between ticagrelor and prasugrel in patients undergoing percutaneous coronary intervention for acute coronary syndrome.

Methods

Platelet function was assessed by impedance aggregometry after 30–90 days of therapy with acetylsalicylic acid and ticagrelor and over 15 days after switching to prasugrel. High-on-treatment platelet reactivity (HRPR) was defined for ADP test results above the upper limit of normal.

Results

A total of 105 patients were included, 81.9% males and 33.3% people with diabetes, with a mean age of 60.8 ± 8.1 years. Mean platelet reactivity was not significantly different between the two antiplatelet strategies, as the prevalence of HRPR (8.6 vs 12.3%, P = 0.50). Switching between the two antiplatelet agents was safe and well tolerated, and effectively reduced platelet reactivity in over 95% of the patients (only 3.8% of the study population displaying ineffective response to both drugs).

Conclusion

Ticagrelor and prasugrel have a similar effect on platelet reactivity. Switching between the two drugs can be safely done.
