Diasporic Consciousness in Jhumpa Lahiri's Novel "The Namesake"
Authors: Dr Shobha Tiwari Ray
Published: April 2024

This study analyses Jhumpa Lahiri's book "The Namesake", with a specific focus on Gogol Ganguli's character and his quest for self-knowledge as an Indian-American. The experiences of alienation, assimilation and hybridity, which are central to Lahiri's examination of diaspora, play a key role in the protagonist's development. The story provides a deep understanding of the dynamic between the original and host cultures, which forms hybridity and challenges the binary concept of identity. The themes of identity, belonging and cultural displacement are prevalent throughout Lahiri's work. This study examines how Lahiri's story sheds light on the intricate process of cultural negotiation and identity creation for diasporic persons by questioning the mechanics of cultural identity in a globalised environment. The results add to our knowledge of the global character of cultural identity and the complexity of diaspora literature.

INSTITUTIONAL WELFARE AND RESILIENCE INITIATIVES FOR DEPLOYED MILITARY PERSONNEL AND FAMILIES: THEORY AND PRACTICE. A CRITICAL REVIEW OF LITERATURE
Authors: Frankline O. Omuse  , Catherine Gachutha
Published: April 2024

The recent unprecedented levels of deployment of troops in operations in the Horn of Africa region has dramatically changed the Military families’ growth due to the large number of troops being deployed. Families get affected by deployment-related family separation, combat injury, and death. With continued involvement in operations, there is a deep concern over parental deployment and its impact on the well-being of military families. Parental absence or loss invokes emotional uncertainty and ambiguity in the family. Through Institutional Resilience programmes, family members can successfully adapt to the situation with significant adversity or trauma through interactions with environmental factors such as community environment, the population, and risk factors. This paper therefore reviews extant conceptual and theoretical literature on common resilience programmes, proposes a theoretical framework for transition and wellbeing of military personnel and their families, proposes a definition for the construct ‘social welfare’ and makes recommendations on resilience and welfare initiatives for adoption by the Disciplined Forces and other organizations with employees in conflict prone areas in the Horn of Africa.

Published: April 2024

In the article, the authors analyze the statistical data of the digital transformation market, and investigate the digital transformation project management system. In the context of the rapid development of Industry 4.0 technologies and the transition of the Russian Federation to a data economy, it is necessary to constantly develop a strategic management system for digitalization and a digital transformation strategy for each enterprise. It is also necessary to analyze and optimize the portfolio of digital transformation projects in order to achieve strategic business goals. Limited resources and constant changes in the context of the external and internal environment of the enterprise dictate the need to select the most effective projects in the company’s digital transformation portfolio and develop tools for the digital transformation project management system. The products and services of digital transformation projects are based on Industry 4.0 technologies or end-to-end information technologies of the “Digital Economy” (artificial intelligence, the Internet of Things, big data and others). The purpose of the research is to improve the management system of digitalization processes and develop tools to support strategic management of digital transformation projects within the project office. The result is the development of a set of tools, including a mechanism for selecting digital transformation projects, and a methodological model for strategic management of digital transformation projects, which provides support to the project office of the enterprise for the organization of portfolio management. The proposed management system also includes a mechanism for choosing an approach to managing digital transformation projects. The leading scientific methods underlying the solution of the problem are systematic and expert methods of analysis, which made it possible to analyze the processes of digitalization and management, systematize the problems and trends in the development of digital transformation of enterprises, and identify the main elements of the project selection mechanism. The results of the study can be applied to manage the digital transformation of enterprises and the transition to the concept of a “smart enterprise” based on Industry 4.0 technologies.

Discovery of new antibiotics using AI-guided spectroscopy and 3D drug-protein computer simulation technologies to combat MDR bacteria-associated mortality
Authors: Chakraborty Asit Kumar , Maity Meghna , Sahoo Sumana
Published: April 2024

Multidrug-resistant (MDR), extensively drug-resistant (XDR), and totally drug-resistant bacteria can cause sepsis and death in patients due to their ability to inactivate most antibiotics, including ampicillin, tetracycline, streptomycin, chloramphenicol, erythromycin, and ciprofloxacin. This paper aims to review recent advancements in synthetic antibiotics, lantibiotics, and phytoantibiotics and to present our research on phytoantibiotics, specifically focusing on CU1 and NU2. While third- and fifth-generation synthetic antibiotics such as meropenem, moxifloxacin, amikacin, and tigecycline are currently relied upon for treating MDR infections, research is underway to develop peptide antibiotics known as lantibiotics (e.g., nisins, bacteriocins, and salivaricins). Lantibiotics such as nisin-A and salivaricin-B have demonstrated efficacy in curing numerous MDR infections, while phytochemicals such as artemisinin and quinine have shown effectiveness against chloroquine-resistant Plasmodium falciparum infections (malaria). In our study, we utilized techniques such as mass spectroscopy, nuclear magnetic resonance, and Fourier transform infrared spectroscopy in conjunction with artificial intelligence (AI) and computer simulation technologies to determine the structure of phytochemicals. Our results revealed that CU1, derived from Cassia fistula bark ethanol extract, exhibits potent antibiotic activity against XDR bacteria by targeting the RNA polymerases of Escherichia coli and Mycobacterium tuberculosis. Consequently, our MDR-Cure extract containing CU1 represents a promising antibacterial Ayurvedic medicine specifically tailored for skin and nail infections. Similarly, NU2 poly-fluorophosphate-glycosides from Suregada multiflora roots ethanol extract exhibited strong inhibitory effects on XDR bacteria by targeting DNA topoisomerase I. Recently, many cyclic peptide antibiotics have been synthesized in vitro using computer-guided AI technologies to predict 3D drug-enzyme interactions and are currently undergoing clinical trials. Our ultimate goal is to combat XDR bacteria-associated deaths, which are predicted to escalate as we approach 2050.

Published: April 2024

This study aimed to investigate the prevalence of anxiety and depression among individuals with ocular prostheses and to identify factors associated with these psychological symptoms. A sample of patients who underwent monocular enucleation and socket implantation participated in the study, responding to digital questionnaires covering demographics, psychosocial factors, and aspects related to their ocular prostheses. Depressive and anxiety symptoms were evaluated using Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7), respectively. Optimal scale regression analysis was employed to explore factors linked to psychological symptoms in ocular prosthesis users. Results from 100 valid participants revealed a 51% prevalence of depressive symptoms and a 45% prevalence of anxiety symptoms. The mean PHQ-9 score was 4.91 ± 1.98, and the mean GAD-7 score was 4.99 ± 2.15. Factors such as undergoing right eye enucleation, longer duration of ocular prosthesis use, comfort with prosthesis wearing, and greater satisfaction correlated with milder depressive symptoms. In terms of anxiety, those who used ocular prostheses due to trauma or tumors were affected by more severe symptoms, while individuals who were comfortable with their prosthesis or using alumina-based prostheses reported fewer anxiety symptoms. In conclusion, ocular prosthesis users wrestle with significant challenges of depressive and anxiety symptoms. Factors including age, household registration, economic status, enucleation side, cause of anophthalmos, prosthetic material, and satisfaction and duration of prosthesis use were associated with depressive or anxiety symptoms. Long-term comprehensive care targeting these vulnerable individuals is imperative to alleviate depression and anxiety.
Utilizing radiomic features of arterial phase computed tomography for delineating parathyroid adenomas from surrounding anatomical structures
Authors: Ezenekwe Chime , Zhang Michael H. , Hussain Irfan , Zhang Yurong , Ginat Daniel T.
Published: April 2024

Aim: The study aimed to correlate radiomic data of four-dimensional computed tomography (4D-CT) with pathology-proven parathyroid adenomas to identify and quantitate select dimensional and textural features that predict parathyroid adenomas with a high degree of confidence, with the ultimate goal of improving the reliability of parathyroid adenoma detection so as to facilitate the subsequent unilateral minimally invasive parathyroidectomy (MIP).
Methods: A total of 144 subjects with a history of neck 4D-CT, parathyroidectomy, and intraoperative pathology-proven parathyroid adenoma(s) were retrospectively reviewed. Following the exclusion of patients with a thyroidectomy, unsuccessful surgery, or indeterminate localization of the parathyroid adenoma on 4D-CT, a preliminary sample of 20 patients was obtained. Four anatomical structures (carotid artery, internal jugular vein, thyroid, and parathyroid adenoma) were segmented twice on 25-second arterial phase axial sections of a 4D-CT, and radiomic data of the shape, first-order, and second-order classes (106 variables) were extracted from the four structures for each patient.
Results: Select radiomic variables among the carotid artery, jugular vein, and thyroid groups exhibited overall significant differences when compared to the parathyroid adenoma data (P < 0.05). Further Tukey’s post hoc analysis revealed that, when the parathyroid adenoma group was treated as the reference, 11/16 shape class, 16/18 first-order class, and 46/69 second-order class variables significantly differ from the carotid artery, jugular vein, and/or thyroid group(s). In addition, we found that the thyroid has distinct textural features compared to the parathyroid group, with 1/18 first-order and 19/69 second-order variables differing significantly between the two (P < 0.05). Notably, the texture variables such as dependence non-uniformity, long run emphasis, run percentage, run variance, and busyness exhibited the highest level of differences between the two groups (P < 0.0001).
Conclusion: The parathyroid adenoma group is associated with a unique set of radiomic variables in comparison to surrounding anatomy such as the carotid artery, internal jugular vein, and thyroid.
Relevance for Patients: The distinct, quantifiable differences in dimensional and textural features serve as a set of signature markers distinguishing parathyroid adenomas from their surrounding structures in 4D-CT. These attributes obviate the need for invasively locating parathyroid adenomas preoperatively, thereby enhancing the utilization rate of MIP, which has a favorable implication in the overall clinical outcomes.

Published: April 2024

The results of research conducted over the past 30 years in the forest ecosystems of Zhytomyr Polissia, in the areas affected by radioactive contamination as a result of the Chornobyl accident. In the course of the research carried out at the Poliskyi Branch of the Ukrainian Research Institute of Forestry and Forest Melioration named after G. M. Vysotsky, methods of forest radioecology, botany, and forestry were used, and the results were processed using statistical analysis. The peculiarities of radioactive contamination of the most common herbaceous and dwarf-shrub plants in the stands of black alder in damp fairly fertile site types were studied. As indicators characterizing these features, we used 137Cs specific activity in the aboveground part of plants and the transfer factor of radionuclide to plant phytomass from the soil. It was found that the highest values of the transfer factor of 137Cs from the soil to the aerial part of the plant phytomass in 1999 are characteristic of ferns: for Dryopteris cristata (L.) A. Gray (276.9 m2∙kg-1∙10-3), Dryopteris carthusiana (Vill.) H. P. Fuchs (236.5 m2∙kg-1∙10-3), Thelypteris palustris Schott (171.2 m2∙kg-1∙10-3), and Athyrium filix-femina (L.) Roth (164.0 m2∙kg-1∙10-3). It was found that among the higher plants, the highest values of this indicator are for the Agrostis stolonifera L. (263.5 m2∙kg-1∙10-3), Galium uliginosum L. (155.8 m2∙kg-1∙10-3) and Maianthemum bifolium (L.) F. W. Schmidt (155.4 m2∙kg-1∙10-3). It was found out that the previously noted trends and interspecific differences in radionuclide accumulation persist after 22 years. It is shown, using the example of three plant species (Lysimachia vulgaris L., Galium uliginosum, and Maianthemum bifolium), that during the observation period (1991-2021) there is a gradual decrease in radioactive contamination of living ground cover plants and the intensity of 137Cs intake into them. This is explained by the decay of the radioactive element, its entry into various perennial components of forest ecosystems, some fixation in the soil, and, possibly, its removal beyond their borders. The established decrease in 137Cs specific activity in the aboveground part of plants is described by linear equations: for Lysimachia vulgaris – Am = –605.34a + 3745.6; R² = 0.98; Galium uliginosum – Am = –5107.5a + 30698; R² = 0.99; Maianthemum bifolium – Am = –4661.6 a + 28280; R² = 0.98. The identified peculiarities of radioactive contamination of various plant species, changes in 137Cs specific activity in them, and transfer factors of the radionuclide from the soil in stands of black alder in damp fairly fertile site types can be used in scientific works to predict possible changes in its redistribution within the ecosystem, as well as in the practice of harvesting medicinal plants in areas contaminated with radionuclides.

Published: April 2024

Запропоновано новий підхід до визначення правильної велосипедної постави, який полягає в удосконаленні динамічного методу налаштування велосипеда зі застосуванням комп'ютерного зору. Цей підхід використовує алгоритми оцінювання пози людини (ОПЛ) для визначення кінематичних показників велосипедиста. Основною метою цього дослідження є розроблення програмного забезпечення, що допоможе визначити та налаштувати правильну велосипедну поставу, а саме висоту сідла, аналізуючи відео за допомогою засобів комп'ютерного зору. Проведено практичний експеримент для порівняння та аналізу результатів ОПЛ п'яти моделей: MediaPipe Pose Landmarker, Movenet (Multipose/Singlepose), OpenPose, YOLOv7. Встановлено, що найкраще для оцінювання пози велосипедиста підходить нейронна мережа BlazePose та її реалізація MediaPipe. Запропоновано математичну модель кінематики колінного суглоба велосипедиста, що дає змогу налаштувати оптимальну висоту сідла. Модель використовує координати стегна, коліна та щиколотки для визначення кута згинання коліна у верхньому положенні обертання педалей та розгинання коліна у нижньому положенні. На підставі цих значень та їх рекомендованих норм, модель визначає наскільки потрібно змінити висоту сідла. Розроблено алгоритм для визначення велосипедної постави, на підставі кутів ключових суглобів (гомілковостопний, тазостегновий, колінний, ліктьовий, плечовий) велосипедиста у конкретний момент часу. Алгоритм реалізовано у програмній системі, що дає змогу аналізувати відео їзди у режимі реального часу. Проведено експеримент з різним налаштуванням висоти сідла 2, 11 і 22 см та отримано рекомендовані значення висоти 11,3, 11,1 і 13,5 см відповідно. Результати цього дослідження показали, що запропонований підхід має високу точність та ефективність у розв'язанні задачі визначення правильної велосипедної постави та налаштування висоти сідла. Майбутні дослідження можуть полягати у врахуванні інших параметрів, які впивають на велосипедну поставу, такі як: зсув сідла, ширина та довжина сідла, Q-чинник, сила натиску на педалі, гнучкість суглобів, інші параметри велосипеда (розміри рами, коліс, розміри та форма керма) тощо.

Published: April 2024

Розроблено підхід до моделювання теплової ефективності гібридного геліоколектора у системі з тепловим акумулятором, що дало змогу запропонувати нову гібридну систему теплопостачання. З'ясовано, що наукова спільнота пропонує істотно збільшити використання відновлювальних джерел енергії (ВДЕ), поступово відміняючи використання традиційних вуглецевих палив. Встановлено, що особливу увагу приділяють розвиткові сонячної енергетики, обсяги якої значно зросли за останні десятиліття. Тому передбачено, що згідно з європейськими енергетичними та кліматичними стратегіями, обсяги енергії, отриманої від сонячних джерел, планують істотно збільшити. Тому розроблено модель системи із гібридним сонячним колектором, що може одночасно виробляти теплову й електричну енергію. Отримано залежності зміни температур теплоносія в гібридному тепловому фотоелектричному геліоколекторі від часу опромінення його сонячною радіацією та охарактеризовано закономірності зміни їх у часі. А також, відповідно, вивчено зміну температури теплоносія у тепловому акумуляторі, як середню, так і в трьох умовних рівних частинах, за його висотою. Встановлено основні закономірності приросту температури, як у гібридному тепловому фотоелектричному геліоколекторі HTPC (англ. Home Theater Personal Computer), так і в тепловому акумуляторі за час проведення досліду. Охарактеризовано зміну миттєвої теплової потужності досліджуваного геліоколектора залежно від обраних чинників впливу. З'ясовано величину середнього коефіцієнта корисної дії та зміну його в часі під час проведення досліду. Встановлено зміну миттєвої питомої теплової потужності досліджуваної системи із HTFPC. Охарактеризовано закономірність зміни теплової ефективності цілої системи із HTFPC упродовж експерименту та з'ясовано ефективність цілої системи за нагромадженням теплової енергії в тепловому акумуляторі. Досліджено отримані основні теплофізичні параметри розробленої системи з гібридним тепловим фотоелектричним геліоколектором для подальшого використання у створенні методики розрахунку цієї системи. А опрацьовані результати досліджень системи з гібридним тепловим фотоелектричним геліоколектором дадуть можливість впроваджувати ці системи в реальних умовах для забезпечення енергією різних об'єктів.

Authors: Мочурад Л. І. , Осідач А. Б.
Published: April 2024

Встановлено, що технологія LiDAR у кластеризації дає змогу підвищити ефективність потокового оброблення даних й отримати точніші результати. Проаналізовано, що проблема створення тривимірного контуру кімнати на підставі даних, зібраних сенсорами виявлення та визначення відстані LiDAR, є ключовим аспектом просторового аналізу, оскільки від цього залежить точність моделі довкільного простору. З'ясовано, що одним з ефективних підходів до вирішення цієї проблеми є використання методу консенсусу випадкової вибірки RANSAC, який дає змогу виділити і відокремити відхилення та випадкові помилки в даних, що отримані зі сенсорів. Запропоновано вдосконалити метод RANSAC шляхом використання технології паралельних обчислень. Це дало можливість розділити початкове завдання на менші частини та обробляти їх одночасно, що сприяє збільшенню швидкості оброблення даних і зменшенню тривалості виконання алгоритму. Оцінено продуктивність методу кластеризації у спосіб запуску програми на виконання 50 разів для послідовного та розпаралеленого алгоритмів, зберігаючи час кожного запуску для розрахунку середньої тривалості виконання. Наведено теоретичну апріорну оцінку показника пришвидшення для різної кількості паралельних потоків. Унаслідок цього здійснено порівняння фактичної ефективності з теоретичною оцінкою. Наведено результати, які вказують на масштабованість підходу та його потенціал для подальшого підвищення ефективності систем за використання більшої кількості обчислювальних ядер. Зменшено тривалість обчислення в 5,5 раза за використання 8 паралельних потоків порівняно з послідовним виконанням, що підкреслює значну перевагу паралельних обчислень під час оброблення великих даних, таких як хмари точок. Наведено результати оцінювання обчислювальної складності послідовного та вдосконаленого паралельного алгоритмів та проаналізовано показники ефективності паралельного. Подальші дослідження полягають у модифікації методів кластеризації на підставі LiDAR для різних застосувань, враховуючи робототехніку та геологічні дослідження, а також розроблення ефективних підходів до паралельного оброблення даних з інших типів сенсорів.

Authors: YANKOVSKAYA GALINA
Published: April 2024

Cultural dynamics during periods of large-scale socio-political reforms differ in that during this period many traditional bureaucratic rules of documentation and archiving are poorly observed. Institutions are changed and eliminated, new problems arise that require prompt solutions, and informal communications are actively used. As a result, many important processes of the reform period in archival funds are presented fragmentarily, with gaps. The article provides an overview of regional archival funds related to the transformation of the cultural sphere in the Perm region in the late 1980s - early 1990s. An overview of a number of funds of the Perm State Archive of Socio-Political History, the State Archive of the Perm Region, and the Archive of city Perm, reflecting various aspects of sociocultural transformations, is given. It is concluded that the documents of organizations and departments form a representative basis for institutional changes analysis, recording new current topics and plots in the field of cultural policy. The second part of the article shows the information capabilities of “letters to power” deposited in regional archives.

Cancer is currently the second leading cause of death in the world after heart disease. Global number of deaths from cancer in 2020 reached 10 million people. In Indonesia, the number of cancer sufferers has reached more than 369 thousand cases. Cancer treatment consists of various types such as intravenous chemotherapy. However, intravenous chemotherapy can cause complications at the injection spot known as extravasation. The incidence of extravasation at RSUP Dr Mohammad Hoesin Palembang is quite high. In 2019 there were 11 extravasation incidents, in 2020 there were 4 incidents, in 2021 there were 17 incidents and in the period January to October 2022 there were 32 extravasation incidents. This study aimed to determine what factors are associated with the incidence of extravasation in cancer patients with chemotherapy at RSUP Dr. Mohammad Hoesin Palembang. The research design used was a cross sectional purposive sampling technique with a total sample of 78 outpatient chemotherapy (One Day Care). Data analysis was carried out using the Chi Square test (X2). Statistical test results showed that gender, age and type of medicine was not related to the incidence of extravasation, while the vein's spot where the IV catheter inserted was significantly associated with the incidence of extravasation with a p value 0.043. It can be concluded that the incidence of extravasation is related to the vein spot where the intravenous catheter is inserted.

This paper investigated the challenges facing teachers in implementing a competence-based curriculum in secondary schools in Uganda. The study employed a qualitative research approach that utilised a case study research design. The sample of the study included 50 teachers who were randomly selected, 4 heads of schools, and 4 education officers who were purposefully selected from 4 public secondary schools found in Gulu City, Uganda. Observations and interviews were used to collect the required information. The findings established that teachers faced a variety of challenges that impeded the effective implementation of a competence-based curriculum in teaching and learning. The researcher also noticed that teachers face a big problem in the implementation of competency-based curricula: insufficient training of teachers and limited engagement of teachers in workshops and seminars that would help enrich them with some skills. So, in a sense, the implementation of CBC started without enough teacher training. Poor infrastructure in schools, limited numbers of housing facilities for teachers, no recommended teaching materials given to teachers, too many students in the classroom, and high computer illiteracy rates among teachers limited the success of CBC implementation in Uganda, especially in government-aided secondary schools. Based on the results of the study, the researcher recommended the following strategies to improve the implementation of CBC in secondary schools in Uganda: revamping teacher professional development; in order to effectively facilitate learning and engage with contemporary learners, teacher educators must be with teaching teachers; establish a robust plan for ongoing constructive interactions by NCDC with all other stakeholders; provide timely resources; and invest enough in schools so that they can deliver the right curriculum. Ensure regular inspection; the inspection role should be equipped to ensure the consistency of the curriculum. Teachers should encourage and practice more project-based learning and also harmonize and implement the language of instruction and evaluation policy clearly to avoid confusion among teachers

The purpose of this study is to construct a social welfare field training curriculum applying the capstone design and verify its effectiveness. In order to examine the effectiveness of the social welfare field training curriculum applying the capstone design, this study conducted a survey before and after the social welfare field training, through which changes in the core competencies of a total of 61 prospective social workers were confirmed. When confirming the effectiveness of the social welfare field training curriculum applying the capstone design, the main results are as follows. First of all, the seven core competencies of prospective social workers were improved overall. Among the seven core competencies of prospective social workers, the score of ‘Core Competency 3: Combination of Research and practice’ improved the most. Based on these results, this study suggested the need for an cooperation system between educational institutions and practice institutions to improve the core competencies of prospective social workers.

Published: April 2024

Due to the inclusion of distributed generation (DG) in microgrids (MGs), the accelerated growth in demand, and environmental concerns, suitable management and operational strategies are imperative. The utilization of wind and solar energy has rapidly increased in MGs. However, due to the uncertainties these systems present, accurately predicting energy generation remains challenging. This necessitates modeling the system’s random variables (such as renewable resource output and possibly load demand) using appropriate and feasible methods. The primary objective of this article is to determine the optimal setpoints for renewable energy sources (RES) and all elements involved in the MG, minimizing the total operation cost. The system comprises wind turbines (WT), photovoltaic panels (PV), energy storage systems (ESS), and electric vehicles (EVs). Weibull distribution and the Hottel and Liu Jordan equations are employed to determine the potential available capacity of wind and solar energy generation, respectively. ESS is utilized to enhance MG performance. For optimal management, a comprehensive mathematical model with practical constraints for each MG element is extracted. An efficient Population-Based Incremental Learning (PBIL) metaheuristic method is proposed to solve the optimization objective in an MG, demonstrating that this energy management system optimizes and effectively coordinates DG and ESS energy generation considering economic considerations. Finally, PBIL is compared with a commonly used model, Particle Swarm Optimization (PSO), across various scenarios, analyzing and evaluating their outcomes, showcasing a reduction in operation costs.

Authors: Flórez Gómez Roberto
Published: April 2024

La hipertensión pulmonar (HP) es un trastorno hemodinámico definido por el aumento anómalo de la presión arterial pulmonar y las resistencias vasculares pulmonares arteriolares, derivado de una disfunción endotelial multifactorial y un remodelado vascular patológico. Se trata de una enfermedad progresiva y grave que conduce en su evolución al fallo del ventrículo derecho (VD) y la muerte prematura por insuficiencia cardíaca. Es importante realizar un diagnóstico precoz de la hipertensión pulmonar, y la ecocardiografía transtorácica destaca como la principal herramienta para detectar esta enfermedad de manera temprana y no invasiva. En este artículo, examinaremos las principales recomendaciones de las Guías de Práctica Clínica de la Sociedad Europea de Cardiología respecto al uso del ecocardiograma en el diagnóstico de la hipertensión pulmonar.
