Published: August 2023

The global malaria community has picked up the theme of malaria elimination in more than 90% of the world’s population in the next decade. Recent reports of Plasmodium vivax (P. vivax) in sub-Saharan Africa, including in Duffy-negative individuals, threaten the efforts aimed at achieving elimination. This is not only in view of strategies that are tailored only to P. falciparum elimination but also due to currently revealed biological characteristics of P. vivax concerning the relapse patterns of hypnozoites and conservation of large biomasses in cryptic sites in the bone marrow and spleen. A typical scenario was observed in Botswana between 2008 and 2018, which palpably projects how P. vivax could endanger malaria elimination efforts where the two parasites co-exist. The need for the global malaria community, national malaria programs (NMPs), funding agencies and relevant stakeholders to engage in a forum to discuss and recommend clear pathways for elimination of malaria, including P. vivax, in sub-Saharan Africa is warranted.

Surgery has played an important role in managing complicated tuberculosis in former Soviet Union countries, including the Kyrgyz Republic. However, published information is limited. This study aimed to document the trend, characteristics and outcomes of tuberculosis patients who underwent thoracic surgery, using routinely collected data. Between 2017 and 2021, 4–7% of tuberculosis patients in the Kyrgyz Republic underwent thoracic surgery in two centres in Bishkek and Osh. In 2021, case records were retrieved in 264 (78%) of 340 patients undergoing thoracic surgery in the country. The most common indications for surgery were pleural exudate/empyema in 127 (44%) and tuberculoma in 83 (32%). Most patients (73%) underwent surgery within 30 days of starting TB treatment. Two-thirds of patients underwent radical surgery, and surgical outcomes were excellent in 99% of patients with one death. Post-operatively, 63 (23%) patients had no TB detected by the histology, with the two most common specified conditions being lung cancer and pulmonary hydatid disease. TB treatment was stopped in these patients. Of the 201 patients with confirmed TB after surgery, TB-treatment success was documented in 163 (81%), died/failure/lost to follow-up in 10 (5%) and not evaluated in 28 (14%). This study shows that thoracic surgery is feasible, safe and effective in the routine programme setting. Recommendations are made to strengthen referral and monitoring systems.

Published: August 2023

Antibiotic resistance poses a growing risk to public health, requiring new tools to combat pathogenic bacteria. Contractile injection systems, including bacteriophage tails, pyocins, and bacterial type VI secretion systems, can efficiently penetrate cell envelopes and become potential antibacterial agents. Bacteriophage XM1 is a dsDNA virus belonging to the Myoviridae family and infecting Vibrio bacteria. The XM1 virion, made of 18 different proteins, consists of an icosahedral head and a contractile tail, terminated with a baseplate. Here, we report cryo-EM reconstructions of all components of the XM1 virion and describe the atomic structures of 14 XM1 proteins. The XM1 baseplate is composed of a central hub surrounded by six wedge modules to which twelve spikes are attached. The XM1 tail contains a fewer number of smaller proteins compared to other reported phage baseplates, depicting the minimum requirements for building an effective cell-envelope-penetrating machine. We describe the tail sheath structure in the pre-infection and post-infection states and its conformational changes during infection. In addition, we report, for the first time, the in situ structure of the phage neck region to near-atomic resolution. Based on these structures, we propose mechanisms of virus assembly and infection.
Characterisation of a Live-Attenuated Rabies Virus Expressing a Secreted scFv for the Treatment of Rabies

Published: August 2023

Rabies virus (RABV) causes possibly the oldest disease and is responsible for an estimated >59,000 human fatalities/year. Post exposure prophylaxis (PEP), the administration of vaccine and rabies immunoglobulin, is a highly effective tool which is frequently unavailable in RABV endemic areas. Furthermore, due to the constraints of the blood-brain barrier, current PEP regimes are ineffective after the onset of clinical symptoms which invariably result in death. To circumvent this barrier, a live-attenuated recombinant RABV expressing a highly RABV-neutralising scFv antibody (62-71-3) linked to the fluorescent marker mCherry was designed. Once rescued, the resulting construct (named RABV-62scFv) was grown to high titres, its growth and cellular dissemination kinetics characterised, and the functionality of the recombinant 62-71-3 scFv assessed. Encouraging scFv production and subsequent virus neutralisation results demonstrate the potential for development of a therapeutic live-attenuated virus-based post-infection treatment (PIT) for RABV infection.
Use of Biolayer Interferometry to Identify Dominant Binding Epitopes of Influenza Hemagglutinin Protein of A(H1N1)pdm09 in the Antibody Response to 2010–2011 Influenza Seasonal Vaccine

Published: August 2023

The globular head domain of influenza virus surface protein hemagglutinin (HA1) is the major target of neutralizing antibodies elicited by vaccines. As little as one amino acid substitution in the HA1 can result in an antigenic drift of influenza viruses, indicating the dominance of some epitopes in the binding of HA to polyclonal serum antibodies. Therefore, identifying dominant binding epitopes of HA is critical for selecting seasonal influenza vaccine viruses. In this study, we have developed a biolayer interferometry (BLI)-based assay to determine dominant binding epitopes of the HA1 in antibody response to influenza vaccines using a panel of recombinant HA1 proteins of A(H1N1)pdm09 virus with each carrying a single amino acid substitution. Sera from individuals vaccinated with the 2010–2011 influenza trivalent vaccines were analyzed for their binding to the HA1 panel and hemagglutination inhibition (HI) activity against influenza viruses with cognate mutations. Results revealed an over 50% reduction in the BLI binding of several mutated HA1 compared to the wild type and a strong correlation between dominant residues identified by the BLI and HI assays. Our study demonstrates a method to systemically analyze antibody immunodominance in the humoral response to influenza vaccines.
Competing Heterogeneities in Vaccine Effectiveness Estimation
Authors: Nikas Ariel , Ahmed Hasan , Zarnitsyna Veronika I.
Published: August 2023

Understanding the waning of vaccine-induced protection is important for both immunology and public health. Population heterogeneities in underlying (pre-vaccination) susceptibility and vaccine response can cause measured vaccine effectiveness (mVE) to change over time, even in the absence of pathogen evolution and any actual waning of immune responses. We use multi-scale agent-based models parameterized using epidemiological and immunological data, to investigate the effect of these heterogeneities on mVE as measured by the hazard ratio. Based on our previous work, we consider the waning of antibodies according to a power law and link it to protection in two ways: (1) motivated by correlates of risk data and (2) using a within-host model of stochastic viral extinction. The effect of the heterogeneities is given by concise and understandable formulas, one of which is essentially a generalization of Fisher’s fundamental theorem of natural selection to include higher derivatives. Heterogeneity in underlying susceptibility accelerates apparent waning, whereas heterogeneity in vaccine response slows down apparent waning. Our models suggest that heterogeneity in underlying susceptibility is likely to dominate. However, heterogeneity in vaccine response offsets <10% to >100% (median of 29%) of this effect in our simulations. Our study suggests heterogeneity is more likely to ‘bias’ mVE downwards towards the faster waning of immunity but a subtle bias in the opposite direction is also plausible.

Published: August 2023

Mycobacterium abscessus is a nontuberculous mycobacterium (NTM) of particular concern in individuals with obstructive lung diseases such as cystic fibrosis (CF). Treatment requires multiple drugs and is characterised by high rates of relapse; thus, new strategies to limit infection are urgently required. This study sought to determine how Bacille Calmette-Guérin (BCG) vaccination may impact NTM infection, using a murine model of Mycobacterium abscessus infection and observational data from a non-BCG vaccinated CF cohort in Sydney, Australia and a BCG-vaccinated CF cohort in Cape Town, South Africa. In mice, BCG vaccination induced multifunctional antigen-specific CD4+ T cells circulating in the blood and was protective against dissemination of bacteria to the spleen. Prior infection with M. abscessus afforded the highest level of protection against M. abscessus challenge in the lung, and immunity was characterised by a greater frequency of pulmonary cytokine-secreting CD4+ T cells compared to BCG vaccination. In the clinical CF cohorts, the overall rates of NTM sampling during a three-year period were equivalent; however, rates of NTM colonisation were significantly lower in the BCG-vaccinated (Cape Town) cohort, which was most apparent for M. abscessus. This study provides evidence that routine BCG vaccination may reduce M. abscessus colonisation in individuals with CF, which correlates with the ability of BCG to induce multifunctional CD4+ T cells recognising M. abscessus in a murine model. Further research is needed to determine the optimal strategies for limiting NTM infections in individuals with CF.

Hematological indices play a prognostic role in human osteosarcoma (OSA), but data are limited in dogs. The aim of this retrospective multicentric cohort study was to investigate the prognostic significance of pre-operative hematological/inflammatory indices in a cohort of client-owned dogs with appendicular OSA receiving standardized treatment. Cut-offs associated with progression-free survival (PFS) for pre-operative hematological values/ratios were established using the minimal p-value approach. Historical prognostic factors were also assessed. Statistical analyses were performed for the whole population and after the exclusion of sighthounds. Fifty-nine dogs were included (13 were sighthounds). Multivariable analysis revealed that a low neutrophil count (<4.37 × 109/L, HR0.28, CI 95% 0.13–0.61, p = 0.001), a high red blood cell count (≥7.91, HR3.5, CI 95% 1.56–7.9, p = 0.002), and a proximal humerus location (HR3.0, CI 95% 1.48–6.1, p = 0.002) were associated with shorter PFS. In the sighthound-only population, only OSA location was significantly associated with PFS in univariable analysis. When sighthounds were excluded, a low neutrophil count, a low monocyte count, and a proximal humerus location were associated with shorter PFS, in multivariable analysis. Neutrophil count and possibly monocyte and red blood cell counts can be useful prognostic markers in canine OSA treated with amputation and adjuvant carboplatin. However, not all indices are appropriate in sighthounds.
Residual Shift of Vibrotactile Perception Thresholds Following Repeated Hand-Arm Vibration Exposure: Screening Parameter for Early Signs of Neurosensory Disorders
Authors: Shibata Nobuyuki
Published: August 2023

Background: The purpose of this study was to validate the applicability of a new screening parameter of VPTW defined as the difference between the ascending and descending thresholds of vibrotactile perception to evaluation of the increasing risk of the neurological components of hand-arm vibration syndrome (HAVS) for repeated exposure to hand-arm vibration (HAV). Methods: Thirty subjects—10 old exposed (G1), 10 old non-exposed (G2), and 10 young non-exposed subjects (G3)—were required to carry out three 3 min grip tasks with exposure to two intensities of HAV at 10 min intervals. Vibration perception measurements, each of which lasted 90 s, were performed at 5 min intervals at the right index finger. Results: VPTWs calculated from pairs of the vibrotactile ascending and descending thresholds at the fingertips were not significantly affected by repeated HAV exposure. Moreover, the VPTWs measured for non-exposed subjects were almost invariant regardless of the subjects’ age or the time elapsed after repeated exposure to HAV. Residual TTSs at 125 Hz gradually recovered in all subject groups under both HAV exposure conditions. The residual TTSs of non-exposed subject groups significantly increased as the number of iterations of HAV exposure increased. Conclusions: VPTWs measured after exposure to repeated HAV are invariant and independent of the individual neurosensory characteristics of the fingertips, which supports the hypothesis that VPTWs can be used as a screening parameter to detect potential patients only with neurosensory components observed as early signs of HAVS.
A Comparison of Numerical Schemes for Simulating Reflected Wave on Dry and Enclosed Domains
Authors: Hien Le Thi Thu , Van Chien Nguyen
Published: August 2023

This paper is to investigate the capability of six numerical schemes to simulate reflected wave over a dry and closed domain with and without building, namely: (a) two proposed 2D numerical models solving the conservation form of 2D Shallow Water Equations (2D-SWEs) by Finite Volume Method (FVM) with Roe and HLLC schemes are invoked to approximate Reimann solver; (b) three options of shallow models in the commercial software Flow 3D based on a non-conservation form of 2D-SWEs and (c) the Flow 3D with turbulence modules. By analyzing flooding maps, the area of the reflected wave, and water level profiles on a dry and closed domain, two proposed models give reasonable solutions, while three options of the shallow module of Flow 3D originate result less accurately when initial wave celerity (c0) is small. The accuracy level will be increased if c0 value increases. The 3D model presented the best performance of the complex flow pattern in the dry and enclosed domain in both cases without and with building.
Gas Loss Mechanism in the High-Pressure Air Cushion Surge Chamber of Hydropower Station for Transient Process
Authors: Xia Yong , Wang Pei , Du Pengxia , Liu Yue , Tang Bihua , Li Xueyu , Zhou Ling , Liu Deyou
Published: August 2023

Water–air interaction (mixing of gas and water and gas dissolution into water) is one of the main reasons for gas loss in air cushion surge chambers. With the increase of water head in hydraulic power generation systems, the heat and mass transfer process at the water–air interface under high-pressure conditions intensifies, and the water–air interaction is further strengthened. If some gas is mixed/dissolved in water and enters downstream pipelines, it will affect the safety of the unit. At present, there has been no theoretical or systematic research on gas loss and related water gas two-phase flow in air cushion surge chambers under high-pressure conditions. Therefore, this article established an air loss model for an air cushion surge chamber based on the VOF model and gas–liquid mass transfer theory. We analyzed the mechanism of gas loss in the gas chamber through simulation and quantitatively expressed the gas loss. The results indicate that during a typical large fluctuation process, the gas–liquid mass transfer process at the water–air interface, air mass, and vortex is very strong, with a pressure chamber of approximately 923.89 m3. The gas dissolved in water enters the water diversion system, with a length of 28.75 m3. High pressure gas enters the water diversion system in the form of air masses. When considering the water inlet on the right side of the air chamber, the total gas loss in the air chamber is slightly lower (854.18 m3) and no mixed air mass was detected entering the connecting pipe.

Published: August 2023

Today, the issue of applying new technologies is acute for a huge number of business areas, due to increased interest from customers, increased security, potential for growth and cost savings. One of the leading industries in the application of new technologies is banking, because its large representatives accumulate significant amounts of money, and are also financial intermediaries, through whose activities the real sector of the country's economy should develop. Based on this, there is a problem of implementing new technologies in banking intermediation, because it is difficult to calculate the payback of their implementation, interest and additional convenience on the part of the client. We consider it necessary to consider this problem, study its effect on statistical data and determine the degree of success of the implementation and features of the new technologies used by banks.

A Modified Technique of Hybrid Multiobjective Genetic Algorithm for Image Fusion
Authors: Kulkarni Jyoti , Bichkar Rajankumar
Published: August 2023

Sensors used in image acquisition. This sensor technology is going on upgrading as per user need or as per need of an application. Multiple sensors collect the information of their respective wavelength band. But one sensor is not sufficient to acquire the complete information of one scene. To gain the overall data of one part, it becomes essential to cartel the images from multiple sources. This is achieved through merging. It is the method of merging the data from dissimilar input sources to create a more informative image compared with an image from a single input source. These are multisensor photos e.g., panchromatic and multispectral images. The first image offers spatial records whereas the lateral image offers spectral data. Through visible inspections, the panchromatic photo is clearer than a multispectral photo however the grey shade image is. Articles are greater clear however nownot recognized whereasmultispectral picture displays one of a kind shades however performing distortion. So comparing the characteristics of these two images, the resultant image is greater explanatory than these enter images. Fusion is done using different transform methods as well as the Genetic Algorithm (GA). Comparing the results obtained by these methods, the output image by the GA is clearer. The feature of the resultant image is verified through parameters such as Root Mean Square Error (RMSE), peak signal to noise ratio, Mutual Information (MI), and Spatial Frequency (SF). In the subjective analysis, some transform techniques also giving exact fused images. The hybrid approach combines the transform technique and a GA is used for image fusion. This is again compared with GA results. The same performance parameters are used. And it is observed that the Hybrid Genetic Algorithm (HGA) is superior tothe AG. Here the only RMSE parameter is considered under the fitness function of the GA so only this parameter is far better than the remaining parameters. If we consider all parameters in the fitness function of the GA then all parameters using a HGA will give better performance. This method is called a Hybrid Multiobjective Genetic Algorithm (HMOGA) [14].

Descolonizar el deseo, desear la descolonización.
Authors: Diaz Santiago
Published: August 2023

En el presente trabajo, desde una perspectiva decolonial y a partir de un estilo ensayístico, proponemos una reflexión sobre lo que denominamos “colonialidad erótica”. Nos interesa entrecruzar el pensamiento filosófico, el estudio de los modos de la colonialidad y las resistencias sensibles que ponen de manifiesto una larga genealogía de violencias múltiples sobre las formas de vida en América Latina. Nuestro aporte en este breve artículo se sitúa desde una mirada descolonizadora de los modos de captura y producción del deseo y las corporalidades, con la finalidad de extender y comunicar la potencia del pensamiento filosófico decolonial, como un ejercicio de resistencia a las tramas diversas en las que se teje el imaginario moderno-colonial, en relación a la manera de comprender la naturaleza del deseo y sus expresiones. Finalmente, postulamos la noción de “reexistencia” como una expresión necesaria para el ejercicio de estos posicionamientos insurgentes descolonizadores.
carpas a las calles o de la fuerza física a la fuerza simbólica. Circo artivista como ritual de transición hacia una identidad feminista.
Authors: Losada Camila
Published: August 2023

La propuesta de este trabajo es comprender el modo en que la performance artivista circense, en contextos de protesta feminista, se constituye en un ritual de transición hacia una identidad feminista; transformando la fuerza física de los cuerpos individuales circenses en una fuerza simbólica intersubjetiva y produciendo agenciamientos y conciencia colectiva. Transversalmente, se cruzan dos ejes de análisis: la performance artivista como acto estético y político ritual multisensorial y la performatividad de género como mecanismo de producción de identidades sexo-genéricas. Propongo un ejercicio analítico-metodológico (Rodriguez, 2012) que permita profundizar en la eficacia de las performances artivistas, teniendo en cuenta la especificidad de las prácticas circenses, y el contexto de lucha feminista en el que se situán, para producir transformaciones en las subjetividades y corporalidades generizadas.
Barreras comunicativas de personas con discapacidad visual desde un enfoque social
Authors: Pinto Lopez Rubén
Published: August 2023

La discapacidad en los últimos años dejó de ser un problema de salud pública por los cambios en la conceptualización y el fortalecimiento de políticas públicas que promueven la inclusión social. Estos cambios permitieron situar a la discapacidad como un objeto de estudio dentro de la sociología, aunque de modo muy parcial. Sin embargo, las personas con discapacidad aún continúan atravesando barreras que, por el estigma, dificultan su inclusión y participación en la sociedad, sobre todo en el ámbito comunicativo. En tal sentido, el objetivo del documento se orienta a describir las barreras comunicacionales a las que se enfrentan las personas con discapacidad visual en Bolivia en el ámbito educativo y de salud, a partir de datos proporcionados por la Encuesta de hogares 2019, desde un enfoque social y de derechos.

Published: August 2023

El cine como recurso didáctico en escuelas tiene historia, pero no está reconocido en el sistema educativo formal de Perú. Se ha identificado que se puede usar para generar debate, introducir o concluir temas, y motivar a los alumnos. Este artículo analiza la experiencia y percepción de docentes de colegios privados en Lima sobre el uso del cine en el contexto educativo. Mediante ocho entrevistas semiestructuradas, se encontró que la integración del cine surge de la iniciativa propia y la formación autodidacta de los docentes. También se identificaron patrones de enseñanza, como el uso predominante de largometrajes en cursos de Humanidades. La habilidad de los alumnos en entornos audiovisuales plantea una oportunidad para integrar los medios de comunicación en la escuela.

Escape a los Andes, rigor histórico y excelencia narrativa
Authors: Salazar del Barrio Juan Carlos
Published: August 2023

El filósofo e historiador escocés Thomas Carlyle dijo alguna vez que la biografía es una suma de anécdotas. Son las anécdotas, entendidas como hechos o detalles circunstanciales, las que finalmente conforman el derrotero de esa gran crónica que es la vida de una persona; es el entorno social, político, económico, religioso, etc., el que matiza y da sentido a esos pequeños acontecimientos. Es precisamente una anécdota lo primero que escuché siendo niño sobre Mauricio Hochschild, una anécdota que refleja muy bien la idea que se tenía entonces de ese empresario minero, como un emprendedor audaz, un hombre que tenía como único límite su propio interés, que levantó un imperio de la nada.
La inteligencia ecológica como alternativas frente a la contaminación ambiental
Authors: Fernández-Dávila Marli Judit
Published: August 2023

El presente trabajo se elaboró en base a una revisión de libros y artículos sobre la Inteligencia Ecológica como una herramienta psicológica que podría desarrollar en el individuo, la capacidad para modificar su comportamiento consumista y adoptar una responsabilidad ética frente la contaminación ambiental que está perjudicando la salud física y mental de todas las personas; a través del cambio de creencias y de la concientización sobre los efectos nocivos que genera cada fase de producción industrial.

Se identifican aquellas barreras psicológicas de inacción frente al cambio climático, entre ellas; la falta de métodos para frenar la contaminación ambiental, las ideologías limitantes, la influencia de las masas que promueven el consumismo, el miedo al cambio, las pérdidas financieras que representa una producción ecológica y la aplicación inadecuada de las campañas de sensibilización, todas ellas denominadas como “Dragones de Inacción” que impiden el desarrollo de habilidades pro-ambientales.

Finalmente, se recomienda al modelo ABC de la Terapia Racional Emotiva Conductual (TREC) de Albert Ellis, como una alternativa frente a la crisis ecológica; para que, con la modificación de creencias irracionales sobre el medio ambiente, se pueda suscitar una conducta pro ambiental en la población. Todo ello, por medio de la aplicación de programas de intervención grupal a nivel educativo y social, con debates filosóficos, empíricos, pragmáticos, que promuevan actitudes prosociales para salvaguardar el bienestar de la persona a través del cuidado de la naturaleza.

El XIX fue el siglo del retroceso y el de la desaparición del vascuence como medio de comunicación en Tierra Estella. Pero evidentemente, quedaron algunos restos.

En este trabajo hemos realizado una pequeña recopilación para conocer la situación actual, de manera que Ángel Sada (Villanueva de Yerri), Lea (Riezu), Jesús Garín y Ramón Pascual (Abárzuza) han contribuido en este estudio sobre la situación del léxico de origen vasco en uso en el habla popular de Tierra Estella en las postrimerías del siglo XX, recogiendo más de 60 voces con sus variantes.

Se prevé la progresiva desaparición de casi todas estas palabras, pero al mismo tiempo que desaparecen los últimos restos, la denominada “lingua navarrorum” renace en Tierra Estella.

La obesidad es una patología de importancia a nivel mundial porque conlleva a una alta carga de mortalidad y morbilidad. El balón intragástrico representa una técnica no quirúrgica empleada cada vez con más frecuencia para lograr pérdida de peso. Si bien, este se considera un método seguro, se han reportado algunas complicaciones desde náuseas y vómitos, hasta eventos adversos graves, tales como perforación. La pancreatitis aguda constituye una complicación muy rara del balón intragástrico y se atribuye su efecto a la compresión directa que ejerce sobre el páncreas. Presentamos el caso de una paciente mujer de 21 años, quien después de 7 meses de colocación de balón intragástrico, cursó con dolor abdominal, náuseas y vómitos, asociados a elevación de enzimas pancreáticas. Se hizo diagnóstico de pancreatitis aguda y se corroboró compresión de la cola del páncreas mediante estudio tomográfico. Se decidió retiro del balón mediante endoscopía, cursando luego con evolución favorable.

Objetivo: Determinar los resultados clínicos y angiográficos en pacientes con aneurismas intracraneales múltiples tratados endovascularmente en una única sesión. Materiales y Métodos: Se incluyó a todos los pacientes mayores de 18 años con aneurismas múltiples (>2), rotos o no rotos, tratados con terapia endovascular en una única sesión entre 2019 y 2021. Se recolectaron los datos clínicos y angiográficos. Se determinó la tasa de oclusión inmediata y del seguimiento. La escala de Rankin modificado se usó para valorar el resultado clínico. Resultados: Se trataron 25 pacientes, de los cuales 14 se presentaron con hemorragia subaracnoidea. Se diagnosticaron un total de 78 aneurismas, de los cuales 59 aneurismas fueron tratados. La localización más frecuente fue el segmento oftálmico. La altura máxima promedio fue de 5.2mm, lo cual tuvo diferencia estadística significativa con el estado de ruptura (p ≤ 0.02). El principal tipo de tratamiento endovascular fue la técnica de remodeling en el 39% de casos. El Raymond Roy inmediato fue I en el 60% y IIIa en el 35% de casos. La tasa de complicaciones fue del 24% y de mortalidad fue del 8%. Conclusiones: El tratamiento endovascular en una única sesión es una opción efectiva y segura en casos de aneurismas intracraneales múltiples en nuestra institución con tasa de oclusión y complicaciones aceptable.

Esta investigación analiza las propiedades psicométricas de la Escala de Cansancio Emocional y confirma su estructura unidimensional. Participaron en la investigación 442 estudiantes de maestría y doctorado de 21 a 55 años (M = 29.52; DE = 5.63). Se realizaron análisis factoriales exploratorios y confirmatorios, análisis de invarianza y análisis de consistencia interna. Los análisis factoriales confirmaron la estructura unidimensional del instrumento (índices de ajuste apropiados) y los coeficientes alfa de Cronbach y omega de McDonald fueron adecuados (α = .883; ω = .883). Se concluye que la Escala de Cansancio Emocional cuenta con las propiedades psicométricas adecuadas para ser utilizada en estudiantes de posgrado de Puerto Rico y es una herramienta práctica y útil en el quehacer clínico y académico de las universidades. Se discuten las implicancias prácticas y limitaciones de los hallazgos.

Published: August 2023

Este estudio analiza las propiedades psicométricas del Inventario de Problemas Interpersonales-32 (IIP-32), la medida más utilizada para evaluar dificultades en las relaciones interpersonales. Una muestra de 2128 participantes completaron el IIP-32 y otras medidas de dificultades interpersonales antes de comenzar un tratamiento psicoterapéutico. Para evaluar la confiabilidad se analizaron medidas de consistencia interna y de homogeneidad de ítems. Se analizó la validez del constructo mediante un análisis factorial confirmatorio y la validez concurrente mediante correlaciones entre el IIP-32 y otras medidas de problemáticas interpersonales. Los resultados muestran excelentes niveles de consistencia interna y homogeneidad de ítems. A su vez, los resultados muestran la validez de constructo y validez de concurrente del instrumento. En síntesis, los resultados del trabajo posicionan al IIP-32 como un instrumento de confiabilidad y validez para estudiar dificultades interpersonales con importantes implicancias para la práctica clínica en Argentina.
Propiedades psicométricas de la Escala de Bienestar Adolescente EPOCH en estudiantes venezolanos

Published: August 2023

El objetivo de esta investigación fue analizar las propiedades psicométricas de la Escala de Bienestar Adolescente (EPOCH) en estudiantes venezolanos. Para ello, jueces expertos procedieron a examinar la adecuación de la traducción de la escala y se ajustaron cinco ítems por medio de una traducción inversa. Luego se aplicó la escala a 523 jóvenes de entre 13 y 18 años (M = 15.19; DE = 1.54; 51% hombres) para después realizar un análisis factorial confirmatorio que comprobó una estructura de cinco dimensiones (índices de ajuste adecuados). Sin embargo, el factor compromiso arrojó algunas cargas factoriales bajas (< .5). Además, una prueba de invarianza determinó que el modelo de medida es el mismo para ambos sexos. Por su parte, la confiabilidad fue apropiada para la escala general y las dimensiones (α y ω > .7), a excepción del factor compromiso. Consecuentemente, se discute esto último y se ofrecen sugerencias respecto a futuras investigaciones.
