The Impact of Platform Encroachment on the Manufacturer’s Financing Strategy
Authors: Bi Gongbing , Pan Hao
Published: March 2023

Manufacturers with limited funds often seek financial help from outside, usually banks or platforms. However, introducing store brand products (platform encroachment) makes platforms form a competitive and cooperative relationship with manufacturers. To investigate how platform encroachment affects the optimal production decisions and the manufacturer’s financing strategy, this paper establishes a stylized model to capture the strategic interaction between a manufacturer, a platform and a bank. The manufacturer sells a national brand product directly through the platform, which owns a competitive store brand product. By analyzing the equilibrium results, we show that although platform encroachment may reduce the manufacturer’s financing cost, product competition always makes the manufacturer bear more losses. In addition, our results also show that the manufacturer is always willing to adopt the platform financing strategy if the platform does not encroach. However, under platform encroachment, the bank financing strategy may be a better choice for the manufacturer, as long as the commission rate is low enough. Moreover, the platform financing strategy is the Pareto-dominant strategy when the commission rate is high. Finally, we verify the accuracy and robustness of the conclusions of the basic model through numerical analysis and extension. Using the results we derive, we explain the market practices and provide valuable guidelines for manufacturers to choose financing strategies under platform encroachment.
Study on the Influence of Initial State on Loess Erosion Characteristics and Microscopic Mechanism
Authors: Zheng Hong , Li Xi-An , Deng Ya-Hong , Hao Zhi-Tao , Wen Feng
Published: March 2023

Because of its loose, porous, and vertical structure, loess easily absorbs water, and it contains a large amount of soluble material, making it susceptible to erosion by water flow from rainfall or irrigation, with potentially disastrous consequences. Damage can result especially from loess slope erosion. In this paper, physical tests and microscopic analysis are used to study loess erosion. The purpose is to explore the internal structure of the soil caused by the infiltration of the water body when it flows through the loess slope, and thus to learn more about the internal mechanisms of surface erosion caused by the migration and relocation of the soil particles on the surface of the slope. Erosion tests of samples with different dry density and water content were carried out. It was found that the amount of erosion decreases with an increase of dry density and increases with an increase of water content. Through physical simulation tests combined with field investigation and analysis, the entire erosion process is divided into four erosion characteristic stages: uniform surface erosion; micro drop pit erosion; micro drop pit bead erosion; and rill erosion. The erosion mechanism and micro mechanism of different erosion characteristics are analyzed and summarized. The influences of different dry density and water content on the erosion process are analyzed and summarized, and the internal mechanism of erosion is revealed from the perspective of microstructure, thereby providing a sound basis for engineering construction and erosion-related disaster management in the Loess Plateau.
Wobbling Fractals for The Double Sine–Gordon Equation
Authors: Maccari Attilio
Published: March 2023

This paper studies a perturbative approach for the double sine–Gordon equation. Following this path, we are able to obtain a system of differential equations that shows the amplitude and phase modulation of the approximate solution. In the case λ = 0, we get the well-known perturbation theory for the sine–Gordon equation. For a special value λ = −1/8, we derive a phase-locked solution with the same frequency of the linear case. In general, we obtain both coherent (solitary waves, lumps and so on) solutions as well as fractal solutions. Using symmetry considerations, we can demonstrate the existence of envelope wobbling solitary waves, due to the critical observation the phase modulation depending on the solution amplitude and on the position. Because the double sine–Gordon equation has a very rich behavior, including wobbling chaotic and fractal solutions due to an arbitrary function in its solution, the main conclusion is that it is too reductive to focus only on coherent solutions.

We obtain some new properties, inequalities, and auxiliary results in mixed-norm spaces Lp→(Rd). In addition, a new concept of mixed-norm Besov space is presented and a new decomposition theorem for mixed-norm Besov spaces is established.
Lower Bounds for Quasi-Cyclic Codes and New Binary Quantum Codes
Authors: Liu Yiting , Guan Chaofeng , Du Chao , Ma Zhi
Published: March 2023

This paper considers three kinds of quasi-cyclic codes of index two with one generator or two generators and their applications in quantum code construction. In accordance with the algebraic structure of linear codes, we determine the lower bounds of the symplectic weights of these quasi-cyclic codes. Quasi-cyclic codes with the dual-containing property enable the construction of quantum codes. Defining the coefficient symmetric polynomials of the generator polynomials gives a concise condition for the dual-containing of the quasi-cyclic codes. The lower bound results can significantly reduce the scope of the search for a larger minimum distance of quasi-cyclic codes. With these algebraic results and computer supports, we obtain classical quasi-cyclic codes with better parameters and some new quantum codes under the symplectic construction. In particular, two examples of the new quantum codes [[63,42,6]]2,[[51,35,5]]2 improve the corresponding codes in Grassl’s code table.
A Brief Introductory Note on the Possible Chaotic Dynamics of the Muon Time Series of Cosmic Rays Measured at Sea Level by a Simple GMT Detector
Authors: Conte Elio , Sala Nicoletta , Arcani Marco
Published: March 2023

After an investigation of the well-known basic properties of muons conducted by the standard model (SM), this paper presents the results obtained for the phase space reconstruction, for the correlation dimension and for the largest Lyapunov exponent of a muon time series detected for a period of about three years (2019–2021) in an Italian laboratory at the sea level. These results confirm that the dynamics of such a time series is chaotic in nature, and therefore open new perspectives in the study of cosmic rays. In the following studies, we will explore if such muon time series have a mono- or a multifractal regime with a complete analysis of all the parameters that usually involve such studies.
Effect of Hydrogen Sulfide on Essential Functions of Polymorphonuclear Leukocytes

Published: March 2023

Impaired polymorphonuclear leukocyte (PMNL) functions contribute to increased infections and cardiovascular diseases in chronic kidney disease (CKD). Uremic toxins reduce hydrogen sulfide (H2S) levels and the anti-oxidant and anti-inflammatory effects of H2S. Its biosynthesis occurs as a side process of transsulfuration and in the disposal of adenosylhomocysteine, a transmethylation inhibitor and proposed uremic toxin. PMNL chemotaxis was measured by the under-agarose method, phagocytosis, and oxidative burst by flow cytometry in whole blood and apoptosis by determining DNA content by flow cytometry and morphological features by fluorescence microscopy. Sodium hydrogen sulfide (NaHS), diallyl trisulphide (DATS) and diallyl disulphide (DADS), cysteine, and GYY4137 were used as H2S-producing substances. Increased H2S concentrations did not affect chemotaxis and phagocytosis. NaHS primed PMNL oxidative burst activated by phorbol 12-myristate 13-acetate (PMA) or E. coli. Both DATS and cysteine significantly decreased E. coli-activated oxidative burst but had no effect on PMA stimulation. While NaHS, DADS, and cysteine attenuated PMNL apoptosis, GYY4137 decreased their viability. Experiments with signal transduction inhibitors suggest that the intrinsic apoptosis pathway is mainly involved in GYY4137-induced PMNL apoptosis and that GYY4137 and cysteine target signaling downstream of phosphoinositide 3-kinase.

Published: March 2023

Owing to the diverse treatment outcomes after a botulinum toxin A (BoNT-A) injection to the external sphincter, this study aimed to develop a new technique: an ultrasound-guided BoNT-A external sphincter injection. This single-center prospective cohort study was conducted at a tertiary medical center in Taichung, Taiwan. From December 2020 to September 2022, 12 women were enrolled. The patients were evaluated for lower urinary tract syndrome using patient perception of bladder condition (PPBC), international prostate symptom score (IPSS), uroflowmetry, post-void residual volume (PVR), cystometry, and external sphincter electromyography. We evaluated the patients the day before surgery and 1 week after the BoNT-A injection. For the patients requiring self-catheterization, we recorded the number of times they required clean intermittent catheterization (CIC) per day before the procedure and 1 month after the procedure. The IPSS, PPBC, and PVR were significantly better after the transvaginal ultrasound-guided BoNT-A external sphincter injection. The number of times the patients required daily CIC was also reduced after the injection. Only one patient developed de novo urge urinary incontinence. Our results demonstrated that a transvaginal ultrasound-guided BoNT-A injection was efficacious and safe in the treatment of underactive bladder.
A Method for Calibrating the Transient Storage Model from the Early and Late-Time Behavior of Breakthrough Curves
Authors: Dallan Eleonora , Bottacin-Busolin Andrea , Zaramella Mattia , Marion Andrea
Published: March 2023

Solute transport in rivers is controlled by mixing processes that occur over a wide spectrum of spatial and temporal scales. Deviations from the classic advection–dispersion model observed in tracer test studies are known to be generated by the temporary trapping of solutes in storage zones where velocities and mixing rates are relatively small. In this work, the relation between the early and late-time behavior of solute breakthrough curves (BTCs) and the key parameters of the Transient Storage Model (TSM) is analyzed using non-asymptotic approximations of the model equations. Two main slopes are identified corresponding to the rising and decreasing limbs of the BTCs which are linked by specific relationships to transport and storage parameters. The validity of the proposed approximations is demonstrated with both synthetic and experimental data. Consistent with the TSM assumptions, the range of validity of the proposed approximations represents the limit of separability between surface dispersion and transient storage and can be expressed as a function of a nondimensional parameter. The results of this work can help environmental scientists identify solute transport and transient storage parameters and support the design of enhanced field tracer experiments.

Published: March 2023

The complex mixture of anthropogenic pressure determines the impact on the marine biota, hampering the ecosystem’s functioning. The coast of Alexandria, Egypt, experiences multiple human pressure, including sewage discharge, engineering activities (urbanization) for armoring purposes, and beach nourishment. Hard-bottom polychaete assemblages are demonstrated to reflect coastal areas’ environmental status, though their use in monitoring programs is uncommon. The sensitivity of hard-bottom polychaete assemblages in depicting variations in environmental conditions of two sites exposed to the discharge of polluted water and three sites exposed to urbanization was analyzed. The high spatial and temporal variation in species abundance and diversity probably hid differences among the assemblages exposed to the two forms of pressure while highlighting differences among sites exposed to the same impact form. In addition, changes in the algal substrate probably influenced the observed pattern. Temporal variation of salinity and differences in biological oxygen demand (BOD) and the organic matter appeared to indirectly affect polychaete abundance and diversity by favoring tolerant algal taxa such as Ulva sp. Contrary to what was expected, assemblage variation due to site-specific environmental features accounted for more than the variations due to the two forms of human pressure in shaping differences among polychaete assemblages.

A significant proportion of surgical patients requiring extracorporeal detoxification (ECD) initially have various hemostasis disorders and associated risks. Extracorporeal treatment can lead to the progression of such pathological conditions, including the development of clinically significant bleeding. The work analyzes modern literature, covering the development of hemostasis disorders during ECD and the possibility of their prevention. Currently, there is no consensus on the most significant causes and mechanisms of coagulation disorders in ECD, often leading to serious bleeding and deterioration in patient outcomes. Researchers agree that a significant influence on the risk of occurrence of coagulopathy is not exerted by the severity of the underlying disease, but by the presence of coagulation disorders before treatment. In patients who initially had coagulopathy and/or thrombocytopenia, bleeding after ECD sessions is observed in 40–50 % of cases. The role of heparin anticoagulation in the development of hemorrhagic complications has not yet received a final assessment. In the majority of publications in the literature, the authors conclude that citrate anticoagulation is effective and safe in various types of extracorporeal detoxification, noting that the use of citrate instead of heparin allows not only significantly extending the life of the filter, but also reducing the risk of developing coagulopathy and bleeding after the procedure. Questions of use, risks, and benefits of citrate anticoagulation over heparin for ECD in surgical patients with coagulopathy require further study.

The article considers the theoretical foundations for assessing and forecasting the sustainability of the development of the Russian economy using artificial intelligence systems. The relevance of the study lies in the fact that in modern conditions the question of the formation of methodological approaches for a balanced sustainable development of the economy is particularly acute. The novelty of the study lies in the fact that an approach is proposed that involves the use of a certain system of macroeconomic indicators that reflect the dynamics of development of both the real sector of the economy and the parameters of the development of the fi nancial sector to predict the GDP of the Russian Federation using the "Perceptron" AI system. An analysis was made of both the dynamics of macroeconomic indicators of the real sector of the economy and the parameters of the development of the fi nancial sector of the Russian Federation. The authors considered the advantages of using the VaR model indicator as a measure of risk to assess the fi nancial risk of reducing the GDP of the Russian Federation. The "Perceptron" program was developed using the Deductor platform to predict the dynamics of the RF GDP. A wide range of fi nancial mathematics tools proposed by individual authors for assessing and minimizing fi nancial risk, including quantile hedging, defi cit hedging with minimal risk, and optimal quadratic hedging, are considered. The architecture of the neural network, in addition to the input layer, has two hidden layers, and an output layer with one parameter. The neural network "Perceptron" shows a high accuracy of the forecast.
Age and sex ratios of wintering Long-tailed Ducks Clangula hyemalis can be determined by analysis of photos of flying flocks at sea: A method description
Authors: Larsson Kjell
Published: March 2023

The West Siberian/North European population of Long-tailed Duck Clangula hyemalis that breeds in Fennoscandia and Northwestern Russia, and winters in the Baltic Sea, has declined by at least 65% since the 1990s and is classified as globally vulnerable. To propose effective management actions to stop the decline, knowledge about demographic parameters is required. A photo survey method by which it is possible, in winter, to collect data on sex ratios and production of first-winter birds is presented here. The plumage traits and bill patterns, which are detectable in photos taken at a distance, are described. The traits can be used to discriminate between three categories of birds: adult males, first-winter males, and females. To extrapolate results from several photo surveys and obtain population-wide estimates of demographic parameters, knowledge about non-random distributions of different bird categories is needed. It was found that different age and sex categories were distributed differently across flocks of different sizes. The required sample sizes and the possible constraints and biases related to the photo survey method are discussed.
El pasado indígena en la historiografía de Catamarca. Una lectura a contrapelo
Authors: Fontenla Manuel
Published: March 2023

A diferencia de lo que sucede con los binomios nación/provincia, archivo/ fuente, regional/local o frontera/estado que cuentan con una larga tradición de debate y estudio en el campo historiográfico argentino, con el binomio pueblos indígenas/historia ocurre más bien lo contrario. Esta es una temáticaque ha permanecido en un largo “vacío historiográfico” y que recién en las últimas décadas ha empezado a ser parte de los debates y estudios actuales. Reconociendo la existencia de perspectivas hegemónicas que invisibilizan la historia de los pueblos indígenas, y perspectivas que buscan renovar miradas historiográficas sobre ella, este artículo se inscribe en un esfuerzo por plantear algunas preguntas referidas a las disputas históricas del pasado indígena en la Historiografía catamarqueña. Para ello se realiza un análisis de autoresclásicos de la historia local, en diálogo con aportes de las perspectivas teóricas provenientes de los estudios de la subalternidad y la crítica poscolonial.

Este texto se presentó en la apertura del Congreso de GETEA con el objetivo de provocar una reflexión que nos movilizara justamente en un momento de crisis. Mi propósito fue pensar cómo comprender la imposibilidad de separar completamente el teatro - que algunos llaman de co-presencial -, de aquello que se realiza por medios virtuales, a partir del contexto de la pandemia de Covid-19. Discuto aquí cuestiones que tienen como principal foco hacer pensar sobre las categorías de análisis que estamos utilizando, algunas veces sin la profundidad que corresponde, si pretendemos sostener discursos de investigación que retroalimenten las prácticas de creación. En este material no trato de identificar teatralistas específicos y sus prácticas de teatro virtual, porque el objetivo fundamental es plantear cuestiones relacionadas a cómo mirar esta enorme variedad de modos creativos que cuyos componentes están mediados por la tecnología en el contexto de la pandemia.
El amor de la estanciera (c.1790/1793), el manuscrito más antiguo del Archivo del INET

A la hora de buscar “testimonios del pasado teatral” (como es el nombre de esta sección), el lugar insoslayable al que debemos acudir es al Archivo del Instituto Nacional de Estudios de Teatro. Ese archivo histórico alberga un riquísimo acervo documental de fuentes para reconstruir la historia de nuestro teatro nacional. La creación del Instituto Nacional de Estudios de Teatro (INET) en 1936 se enmarcó en la política cultural desarrollada por la Comisión Nacional de Cultura que sostenía la función social y educativa del teatro. Así, el Instituto Nacional de Estudios del Teatro con su Biblioteca, Archivo, Publicaciones y Museo, se creó con el objetivo de propender al estudio y divulgación de la historia del teatro nacional. Para ello, el INET llevó adelante una intensa labor de estudio y difusión de los antecedentes e historia del teatro nacional a lo largo de sus ochenta y cinco años de historia y continúa su labor hasta hoy.

Mapping Chinese Medical Entities to the Unified Medical Language System
Authors: Chen Luming , Qi Yifan , Wu Aiping , Deng Lizong , Jiang Taijiao
Published: March 2023

Background

Chinese medical entities have not been organized comprehensively due to the lack of well-developed terminology systems, which poses a challenge to processing Chinese medical texts for fine-grained medical knowledge representation. To unify Chinese medical terminologies, mapping Chinese medical entities to their English counterparts in the Unified Medical Language System (UMLS) is an efficient solution. However, their mappings have not been investigated sufficiently in former research. In this study, we explore strategies for mapping Chinese medical entities to the UMLS and systematically evaluate the mapping performance.

Methods

First, Chinese medical entities are translated to English using multiple web-based translation engines. Then, 3 mapping strategies are investigated: (a) string-based, (b) semantic-based, and (c) string and semantic similarity combined. In addition, cross-lingual pretrained language models are applied to map Chinese medical entities to UMLS concepts without translation. All of these strategies are evaluated on the ICD10-CN, Chinese Human Phenotype Ontology (CHPO), and RealWorld datasets.

Results

The linear combination method based on the SapBERT and term frequency-inverse document frequency bag-of-words models perform the best on all evaluation datasets, with 91.85%, 82.44%, and 78.43% of the top 5 accuracies on the ICD10-CN, CHPO, and RealWorld datasets, respectively.

Conclusions

In our study, we explore strategies for mapping Chinese medical entities to the UMLS and identify a satisfactory linear combination method. Our investigation will facilitate Chinese medical entity normalization and inspire research that focuses on Chinese medical ontology development.

Published: March 2023

Aeromonads resides in aquatic environments and infect humans and fish among other animals. This opportunistic pathogen is predicted to have several pili and fimbriae genes which may promote biofilm formation and attachment affecting the infection process. The present study compares biofilm formation and subsequent infection on MDCK cell lines using wildtype Aeromonas hydrophila and putative type IV pilin biosynthesis gene mutant generated by standard protocol. The results indicate the involvement of putative pilus biosynthesis operon AHA0686-AHA0696 in biofilm formation of Aeromonas hydrophila and infection of MDCK cells. In silico analysis of the operon predicts to contain putative type IV pili and pilin biosynthetic genes. Detailed analysis of these genes is required to evaluate the applicability of these mutant strains as potential vaccine candidates.

The use of flipped learning in ESP (English for Specific Purposes) classes may have not been frequently portrayed. This recent study attempts to depict the implementation of a flipped learning model applied in an English for Management course. A single qualitative case study was applied. One lecturer of the English for Management course was involved in this study. The data were obtained using interviews and observations. The findings revealed that the flipped learning in the ESP class is realized in the following steps: 1) distributing materials and tasks to students, 2) providing guidance for students to discuss the materials and tasks, 3) assessing students with tests or quizzes, and 4) providing reinforcement for students in face-to-face meetings. The lecturer admitted that she encountered some challenges using flipped classrooms in ESP classes: the issues of bandwidth, students’ readiness, the lecturer's need for non-authentic materials, and the institution's policy on curriculum and facilities. Potential research in investigating ESP students’ perceptions of the use of flipped learning is strongly advised.

The authors analyzed the case histories of 3 954 patients aged 15–86 years with varying degrees of neurological deficit who had received treatment from 2010 to 2020 in the city neurology department. All patients underwent general clinical and neurological examinations, electrocardiography, clinical laboratory and biochemical tests and, of course, the classical Wasserman test. In addition, ophthalmological, immunological, neurophysiological, neuropsychological and radiological studies were performed. We present a clinical example of early meningovascular neurosyphilis against the backdrop of right hemispheric cerebrovascular accident (CVA). Difficult diagnosing due to the bias of data on CVA, the peculiarities of the disease course and the cumulative neuroimaging data allow the authors to assume a clear dependence of meningovascular syphilis of the nervous system on constitutional variations and/or anomalies of the arteries of the circle of Willis. Constitutional variations and/or anomalies in the development of human cerebral arteries are considered as an additional risk factor for CVA syndrome during infectious processes of the brain with other things being equal.
ACTUALITIES OF EXCISE TAXATION HARMONIZATION OF ENERGY PRODUCTS IN THE EU AND UKRAINE

Published: March 2023

Introduction. The legal framework for tax administration is one of the important components of the harmonization of Ukrainian legislation with EU standards. The area of taxation of energy products is especially relevant today, because with the Russian invasion in Ukraine, there is a total deficit and an increase in prices for energy products. Instead, the taxation of such goods is the least harmonized with EU standards among of all excise goods. The unification of excise tax rates on energy products with the requirements of the relevant EU directive can further provoke the price growth, which is extremely undesirable in the current situation.

The purpose of the article is to generalize scientific and legal approaches to the characteristics of excise taxation of energy products, to outline problematic aspects of the harmonization of the relevant directive in this area, to develop proposals for improving excise taxation of energy products in Ukraine.

Results. The main provisions of Council Directive 2003/96/EC on excise taxation of energy products are analyzed. It has been established that the norms of the Tax Code of Ukraine do not comply with the provisions of this directive in terms of: the list and structure of energy products, which are the subject to excise tax; the amount of tax rates; provision of tax preferences. Probable directions for reforming the EU legislation on excise taxation of energy products are outlined. Monitoring of legislative activities on taxation of energy products in Ukraine was carried out.

Conclusions. As a result of the research, the conclusion is substantiated that at the current stage, the tax policy in the field of excise taxation of energy products, focused on the socio-economic realities of Ukraine, will be more justified than on the priorities of harmonization to EU standards. However, in order for Ukraine's European integration progress not to slow down due to the lack of reforms in terms of harmonization of the studied area, it is necessary to hold a number of consultations with EU institutions regarding the postponement of key issues of taxation of energy products
Si-based mid-infrared photodetector with dynamic Schottky barrier height modulation applicable for synchronous detection
Authors: Ajiki Yoshiharu , Kan Tetsuo
Published: March 2023

We have proposed an electrical shutter operation of a nano-antenna infrared photodetector using Schottky barrier height (SBH) modulation, where the SBH is modulated by a reverse bias voltage V
b applied to the detector. The inhomogeneity of the Schottky junction may be dominant in the mechanism of barrier height reduction. Compared to the photocurrent i
ph obtained by modulating the frequency of on–off of the incident light, the proposed method yields almost the same value. Therefore, it can be concluded that the proposed method is capable of synchronous detection measurement. In addition, since the proposed method does not require a mechanical shutter, it is a compact system that can be used in very small electrical equipment.
Temperature evolution of the Fano line shape in the Raman spectra of BaTiO3 nanoparticles

Published: March 2023

The Fano line shape at about 185 cm−1 is observed in temperature-dependent Raman spectra of BaTiO3 nanoparticles. The dip structure appears at the low-energy side, indicating a positive asymmetric parameter q, which is assigned to the interference between a central peak from the quasi-elastic scattering mode and the A(TO) vibrational mode around 180 cm−1. Furthermore, the relation between the phase change of BaTiO3 nanoparticles and the Fano line shape is discussed. This work deepens the understanding of the mechanism underlying the Fano line shape in Raman spectral and provides a powerful strategy to characterize phase change of the nanostructured BaTiO3.

Introducción: el foramen oval permeable (FOP) se ha asociado a eventos embólicos sisté- micos y la evidencia a favor del cierre viene en aumento. Nuestro objetivo es describir cuáles son los principales desenlaces clínicos y las complicaciones del cierre percutáneo del foramen oval permeable.

Material y métodos: de manera retrospectiva, se registraron pacientes desde el 1.º enero de 2016 a 1.º septiembre de 2021 que fueron sometidos a cierre percutáneo del FOP. Se evaluaron desenlaces inmediatos (<72 horas), desenlaces clínicos de manera temprana y tardía. Se evaluó la mortalidad intrahospitalaria y durante el seguimiento por registro de historia clínica o llamada telefónica.

Resultados: se incluyeron 40 pacientes sometidos a cierre percutáneo FOP. Seguimiento medio de 2.3 años, la edad media fue de 43 ± 13.6 años, 7% eran mayores de 60 años, el 72.5% mujeres, el 25% hipertensos, 20% diabetes, 10% historia de migraña. La media de RoPE score fue seis puntos y 50% un puntaje mayor a siete. Del total de casos se presentaron tres (7.5%) eventos adversos graves, cuatro complicaciones inmediatas. En el seguimiento, en 2.5% se presentaron eventos tempranos dado por el desarrollo de fibrilación auricular y 2.5% de eventos tardíos por recurrencia de ACV. No se presentaron muertes de causa neurológica y reportamos supervivencia de 100%.

Discusión: en nuestra experiencia, destacamos un bajo porcentaje de eventos adversos graves. Un número bajo de eventos inmediatos, tempranos y tardíos con una supervivencia 100% lo que demuestra excelentes resultados para cierre percutáneo de FOP

Introducción: El 10% de los infartos agudos de miocardio se presentan en ausencia de enfermedad coronaria aterosclerótica obstructiva (MINOCA). MINOCA representa un grupo de condiciones que comparten la ausencia de estenosis mayor al 50%. Se desconocen las características de la población afectada con MINOCA a nivel regional. Se propone caracterizar la población con MINOCA e identificar factores asociados a desenlaces adversos.

Material y métodos: Estudio analítico tipo cohortes que indentificó diferentes características en pacientes con MINOCA en un centro de tercer nivel de Pereira. Entre enero 1 de 2019 y Diciembre 31 de 2020 se revisaron 1.500 arteriografías coronarias las cuales 292 cumplieron criterios angiográficos de MINOCA y de éstos, 163 pacientes cumplieron los criterios de inclusión. El desenlace primario fue un compuesto de hospitalización por angina/insuficiencia cardiaca, terapia de reperfusión, muerte por causa cardiovascular y por cualquier causa a 6 meses y 1 año.

Resultados: La mediana de la edad fue de 64 años, 54% (n=88) eran hombres. La hipertensión arterial fue la comorbilidad más prevalente (n=100; 61,3%), la presentación electrocardiográfica más frecuente fue la inversión de la onda T (29,7%; n=47). El 19,3% (n=28) y el 25,5% (n=37) presentaron algún desenlace a 6 meses y 1 año. La mortalidad al año se presentó en el 5,5%. En el análisis multivariado la troponina inicial, la insuficiencia aórtica moderada a severa y el bloqueo de rama derecha se asociaron al evento.

Conclusión: Se presentó el estudio con población más grande en Colombia en una cohorte de pacientes con MINOCA identificando factores asociados a desenlaces adversos.
