¿COMPRENDES LO QUE LEES? (Hch 8,26-40). UNA INTERPRETACIÓN PRAXEOLÓGICA
Authors: Triana Rodríguez Jorge Yecid
Published: July 2023

El estudio de la perícopa de Felipe y el Eunuco, Hch 8,26-40, titulada “¿Comprendes lo que lees”?, proporciona una serie de elementos que sirven de base para elaborar una metodología de la enseñanza bíblica aplicable a la catequesis. Los aportes de los diversos métodos exegéticos, tanto diacrónicos como sincrónicos, se emplean para brindar una visión más amplia del texto sagrado y se articulan siguiendo los pasos metodológicos de la praxeología del ver, juzgar, actuar y devolución creativa. El primer paso del ver se comprende como el análisis del contexto –remoto e inmediato– de la perícopa y los diversos elementos narrativos que los componen: personajes, situaciones y lugares. El momento del juzgar se realiza estableciendo la estructura de la perícopa, un análisis semántico-literario de la misma y enfatizando los paralelos con el AT, en los que se parte de un breve análisis del texto hebreo. El momento del actuar lleva a proponer los aportes metodológicos que el texto contiene en clave de enseñanza bíblica aplicada en la catequesis. Por último, se proponen unas conclusiones a modo de devolución creativa que pueden enriquecer la praxis catequética desde los textos bíblicos.

THE QUESTION OF THE MEDIATION OF MARÍA. ANALYSIS IN CONTEXT EGYPTIAN
Authors: Abdelmalak Ashraf
Published: July 2023

¿Shall we call Mary as a mediator of grace? The present article seeks to provide an an-swer to this question based on the Catholic doctrines, with particular emphasis in the Egyptian context given the fact that it can serve as an example of an ecumenical and interreligious context (in which there are the Coptic orthodox church, the Egyptian protestants and the Muslims). The purpose of such a research is to promote an ecumenical dialogue and to encourage an interreligious comprehension through a new mariological approach to Mary`s role as mediator. This study presents the catholic doctrines on Mary`s mediation and summarizes the position of the Coptic orthodox church and the Egyptian protestants on such a question, in order to explore the possi-bilities to build an interreligious dialogue with Muslim faith based on the recognition of her mediation.

Se trata de un libro en colaboración que forma parte de la Colección Logos de la Escuela de Ciencias Humanas y del Centro de Estudios Teológicos y de las Religiones (CETRE) de la Universidad del Rosario, cuyo director es el editor académico del libro que reseñamos, Dr. Carlos Miguel Gómez, especialista en filosofía de la religión. Los autores de este texto son algunos filósofos y otros sociólogos, todos estudiosos del tema de la religión y sobre todo interesados en las características que ella adopta en la denominada época postsecular. Concepto que han decidido adoptar siguiendo a Haber-mas y Mardones, tal y como se señala en el prefacio, porque el término asu-me la secularización como un fenómeno que cobra diversas dimensiones y procesos contextualmente diversificados, pero, a la vez, permite afirmar la presencia de la religión en el mundo moderno e incluso su deseabilidad (cf., p. 13). Por tanto, el tema amplio del libro es la relación entre religión y racionalidad en un contexto de pluralidad religiosa. Pero centrándose en identificar las transformaciones que la religión adopta en el contexto señalado.

EL EPISCOPADO CHILENO Y EL COMPROMISO SOCIAL DEL CATOLICISMO PRECONCILIAR: 1925-1964
Authors: Brito Rebeco Edison Gabriel
Published: July 2023

La comprensión de la vida de la Iglesia en Chile durante gran parte del siglo XX se en-tiende por una clara tendencia a lo social al interior del catolicismo chileno. Una toma de conciencia que se profundizará en el Episcopado nacional después de la separación de la Iglesia y del Estado en 1925. Acontecimiento que será de gran significación en la historia de la Iglesia al dar la posibilidad de una nueva estructuración y organización de ésta. Por una parte, y después de una ardua discusión zanjada por la Santa Sede, se privó al Partido Conservador del peso político que ejercía al interior de la Iglesia al ser el único partido de los católicos. Y en segundo lugar, la Iglesia buscará progresi-vamente una definición de su ser a partir de su misión entendida cada vez más como un servicio. Al profundizar esta dimensión misionera se insistirá en un humanismo cristiano que subraya la dignidad de todos hombres. Con la publicación de un conjunto de escritos sociales, el Episcopado chileno diag-nosticará una precaria situación social enmarcada dentro de un contexto internacio-nal muy complejo. Con el Concilio Vaticano II, la jerarquía chilena buscará impulsar una profunda reforma y renovación de la sociedad al tomar una posición clara frente a los problemas sociales que la aquejan. La reforma agraria de 1962 se enmarca entre una de las iniciativas del Episcopado.

DIOS PADRE NOS AMA GRATIS
Authors: Cardona Ramírez Hernán
Published: July 2023

Nicodemo, un judío, fariseo y maestro de ley, creyó estar en comunión con Dios por sus cualidades. En el diálogo con Jesús (Jn 3,1-21), descubre que el amor de Dios está presente desde el inicio de la historia: Dios nos amó primero (1Jn 4,19). ¿Pero si un hombre piadoso y fiel como Nicodemo no está en comunión plena con Dios, entonces quién? ¿Para qué ser creyente y practicar una religión? ¿Tiene sentido la ley? ¿Cómo se debe comportar el ser humano cuando queda cara a cara con el amor gratuito de Dios? A estas preguntas quiere responder el presente artículo, con base en unas ano-taciones bíblicas y teológicas, capaces de ofrecer algunas orientaciones para obrar como Jesús de Nazaret, en medio de la realidad actual.
UNA APROXIMACIÓN A LA FAMILIA Y AL MATRIMONIO DESDE EL MAGISTERIO DEL PAPA FRANCISCO
Authors: Durán Donoso Cristina
Published: July 2023

Este trabajo busca mostrar la propuesta que presenta el Papa Francisco en materia de familia. A un año de su pontificado, comienza con un ciclo de Catequesis sobre la familia durante el año 2014 y en el 2015, convoca a dos Sínodos “Los desafíos de la familia en el contexto de la nueva evangelización” y “Vocación y misión de la familia en la Iglesia y en el mundo” y durante el año 2016 toma sus resultados y los plasma en la exhortación apostólica post sinodal Amoris Laetitia. No pretende modificar la doctrina de la Iglesia en materia de familia, más bien, de modo muy personal y con la mirada puesta en Jesús, toma los documentos de Iglesia sobre la familia, se centra en las enseñanzas de sus predecesores Juan Pablo II y Benedicto XVI y desarrolla una actualizada mirada del Evangelio destacando la misión, el acoger, el discernir y el acompañar como actitudes necesarias que la Iglesia debe tener para con los matrimo-nios y las familias en nuestro tiempo.
PENSAR UNA PEDAGOGÍA TEOLÓGICA DE LA ESPERANZA
Authors: Espinosa Arce Juan Pablo
Published: July 2023

La presente contribución se propone pensar algunas pistas acerca de lo que deno-minamos una “pedagogía teológica de la esperanza”. Afirmar que el cristianismo es la religión de la esperanza en el Reino de Dios, en la resurrección, en el triunfo de la justicia, de la paz y del amor, en que creemos que ella actúa en medio de nuestra his-toria, representa, a nuestro entender, una provocación profética en este tiempo en el cual se afirma la supremacía de un sujeto autosuficiente, muchas veces desprovisto de la capacidad de imaginar el futuro ya que ha naturalizado la realidad que lo envuelve, un sujeto que ha ido perdiendo la esperanza y la conciencia de la utopía. Es por ello que creemos que es necesario favorecer algunas claves para reeducar la esperanza y la conciencia utópica, como espacios de realización de lo humano, tanto a nivel personal como comunitario.

LA ARQUITECTURA RELIGIOSA ACTUAL EN DIÁLOGO CON LA CULTURA CONTEMPORÁNEA
Authors: García-Lozano Rafael Ángel
Published: July 2023

La proyección y creación de espacios para el culto cristiano ha sido una constante a lo largo de la historia de la Iglesia y no lo es menos en nuestros días. Dejando considera-ciones cuantitativas al margen, el hombre y la cultura contemporáneos siguen deman-dando la construcción de estos espacios, convenientemente ajustados a la condición propia del mundo actual. Por ello el templo cristiano está llamado a trazar puntos de encuentro con la cultura en que se inserta. Es por ello que en este trabajo transitamos por algunos de los aspectos que tienen más íntimamente que ver con la dimensión ad extra tanto de la Iglesia como de la propia arquitectura religiosa contemporánea. Ello requiere que planteemos nuestro estudio orientados desde la clave más estrictamente misionera de la comunidad eclesial. Porque, ciertamente, una sociedad cada vez más globalizada exige que la catolicidad de la Iglesia esté a su altura. Así, partiendo de la esencial constitución misionera de la Iglesia, abordamos la importancia que la secula-ridad y el diálogo tienen para la arquitectura religiosa actual.
EL CONCEPTO DE ESPONSALIDAD EN LAS CATEQUESIS DE SAN JUAN PABLO II SOBRE LA TEOLOGÍA DEL CUERPO
Authors: Torres Burgos Manuel
Published: July 2023

Cuando el joven Cardenal Wojtyla fue elegido Papa el 16 de octubre del 1978, su pri-mera encíclica se convirtió en la clave de comprensión para su pontificado: Redemp-tor hominis. Dirigió su mirada a los últimos años del siglo XX sobre la Iglesia y la “familia” humana contemporánea buscando hacer un reclamo para volver la mirada a Cristo redentor. Al poco tiempo de este “programa pontificio”, Juan Pablo II comienza el 5 de septiembre de 1979 hasta el 28 de noviembre de 1984, una serie de catequesis sobre “el valor divino del amor humano”. Estas surgen a modo de preparación del Sí-nodo de los obispos que se celebraría en Roma en 1980 y que llevaría por título “Sobre los deberes de la familia cristiana”, pues en ella –la familia– se puede reconocer la comunidad humana y cristiana que es, desde el principio, fundamental para la vida del ser humano, la Iglesia y el mundo. Al final de estas audiencias de los miércoles, el Papa Wojtyla afirmó que este fue un camino para exponer el amor humano en el plan divino por medio del anuncio de la redención y la sacramentalidad del matrimonio.

A Review of the Physiological Role of Hypocretin in the Ventral
Tegmental Area in Reward and Drug Dependence
Authors: Kourosh-Arami Masoumeh , Komaki Alireza , Gholami Masoumeh
Published: July 2023

Orexin (OX, hypocretin: HCRT) as a neuropeptide is produced in a distinct population
of neurons in the posterior lateral hypothalamus (LH). OX neurons implicate in reward function.
OX makes a main input from the hypothalamus to the ventral tegmental area (VTA) of the midbrain.
OX, through OX receptors (OXR1, OXR2) activates VTA dopamine (DA) neurons. VTA neurons
are involved in reward processing and motivation. In this review, we will discuss the OX effect
on addiction through VTA activation and related areas of the brain.

Published: July 2023

Chemical libraries and compound data sets are among the main inputs to start the drug
discovery process at universities, research institutes, and the pharmaceutical industry. The
approach used in the design of compound libraries, the chemical information they possess, and the
representation of structures, play a fundamental role in the development of studies: chemoinformatics,
food informatics, in silico pharmacokinetics, computational toxicology, bioinformatics, and
molecular modeling to generate computational hits that will continue the optimization process of
drug candidates. The prospects for growth in drug discovery and development processes in chemical,
biotechnological, and pharmaceutical companies began a few years ago by integrating computational
tools with artificial intelligence methodologies. It is anticipated that it will increase the
number of drugs approved by regulatory agencies shortly.
One High Voltage Regulation Method and Related Control Strategy in the
DC Transmission System
Authors: Ji Li , ZhenYu Guo , Xue You Zhang , Dao Jun Huang
Published: July 2023

Background:

With the development of power transmission system, the problem of small
transmission capacity and low power quality of traditional AC power distribution methods is becoming
increasingly prominent. The DC power distribution method promotes its own rapid development
because of its suitability of connection between distributed generation and grid, high power
quality, large power supply capacity, low line cost and high reliability.

Objective:

In order to improve the transient performance when the system power fluctuates, a control
method that can perform voltage regulation to the DC system is designed in the process of calculating
the power command value of each converter station at the system level control. Simulation
results show that the designed control method can effectively improve the inertial characteristics and
transient response of DC transmission system.

Methods:

Aiming at the shortcomings of slow response speed and poor stability when the traditional
dual closed-loop PI controller is used as a converter level controller, a sliding mode controller is
designed. Simulation results show that the designed sliding mode controller can improve transient
characteristics of voltage regulation.

Results:

Voltage control strategy of the DC transmission network based on the converter station is
verified.

Conclusion:

A voltage control strategy based on distributed generation and secondary load switching
is designed. The simulation verifies the effectiveness of the designed control strategy.
Chalcogenides: Bulk and Thin Films
Authors: Srivastava Anchal , Shukla Rajesh Kumar , Srivastava Priyanka , Chandra Pramesh , Kumar Nishant
Published: July 2023

Chalcogens are the chemical elements of group 16 of the periodic table. Oxygen is treated separately from other chalcogens; it is even excluded from the term ‘chalcogen’ altogetherdue to its very different chemical behaviour from sulfur, selenium, tellurium and polonium. The heavier chalcogens have vacant d orbitals. A chalcogenide consists of at least one chalcogen element and one electropositive element. The term chalcogenide is more commonly reserved for sulfides, selenides and tellurides rather than oxides. The interest in these materials arises particularly due to their ease of fabrication in the form of bulk and thin films. Generally, chalcogenides have a large glass-forming region and thus, their physical properties can be tuned via chemical composition. These glasses have drawn great attention due to their striking electrical, optical and thermal properties, which ary with composition, heat treatment, irradiation, glass forming methods, etc. There is a high tendency for the atoms to link together to form link chains in chalcogenides. In general, the atomic bonding is more rigid than that of organic polymers and more flexible than that of oxide glasses. This chapter presents the method of fabrication of chalcogenides in bulk and thin film forms.

Published: July 2023

Observation of at least two coexisting switchable ferroic states viz., ferromagnetic, ferroelectric, and/or ferroelastic at room temperature with promising coupling among order parameters, has made BiFeO3 a highly explored material in the field of multiferroics and/or magnetoelectric multiferroics, which creates the possibility for its application in various technological devices such as spintronics, spin-valve, DRAM, actuators, sensors, solar-cells photovoltaic, etc. Intrinsically, its low coupling coefficients, difficulty to prepare in pure phase in bulk, high leakage current, etc. have restricted BiFeO3 from technological reliability. However, the effect of doping with iso- and alio-valent ions, nanostructure, thin-film-form and nanoparticles, etc., has been carried out to improve its physical properties by several research groups over the decades. In this chapter, the structural, luminescence, and dielectric properties of samarium (Sm3+) doped BiFeO3 nanoceramics synthesized using a modified gelcombustion route are discussed in detail. The effect of Sm3+ doping in BiFeO3 is explored using the X-ray diffraction (XRD) technique. The XRD studies exhibit a possible structural phase transition above Sm3+ doping of 15% from rhombohedral (R3c) space group to the orthorhombic (Pbnm) space group. The dielectric study shows interesting behavior accompanied by structural transition. Our study suggests that Sm3+ doping plays an important role in governing the structural, luminescence, and dielectric properties of BiFeO3 samples.
Investigation on Various Polymer Electrolytes for Development of Dye Sensitized Solar Cell
Authors: Chawla Priyanka , Trivedi Shivangi , Pooja Kumari
Published: July 2023

Dye sensitized solar cells (DSSCs) based on TiO2 nanoparticles film have attracted extensive attention from both industry and academia. Generally, the liquid electrolyte is used in dye sensitized solar cells, but the vaporization of liquid electrolyte hinders its commercialization as its affects its stability. And also the reduction in performance of dye sensitized solar cells was observed due to electron recombination in semiconductor liquid electrolyte interfaces. The situation worsens when the photoanode is in contact with the vaporization of electrolyte solution that affects the charge distribution at the semi conductor electrolyte interface and initiates photo corrosion on the photoanode. With the finding of ionic conductivity in polymer, electrolytes complexed with salt give a breakthrough to the development of DSSC devices. Various types of electrolytes have been developed and tested in different DSSCs configurations to overcome this problem. Among all polymer electrolytes, PEO (Polyethylene oxide) based polymer electrolyte has shown excellent performance in different electrochemical application areas. In DSSCs, it is also considered a novel candidate due to its excellent ability to form complexes with ionic salts. Poly(vinyl alcohol) (PVA) is also a promising candidate acting as a host polymer due to its inherent characteristics like high mechanical strength, good tensile strength, high temperature resistance, non toxicity, good optical properties and high hydrophilicity. PVA have a large extent of poly hydroxyl group, which makes PVA highly hydrophile. It also offers other advantages like excellent chemical stability, ease of preparation, and flexibility. In the present paper, we review different types of polymer electrolytes which have been used for improving the performance and stability of DSSCs.

Ionic liquids (ILs) have shown immense potential as suitable alternatives to environmentally damaging volatile organic solvents (VOS). These unique materials possess very unusual physicochemical properties, such as low melting point, high boiling point, excellent thermal and chemical stability, large electrochemical window, very low volatility and high conductivity. One of the most important features associated with ILs is that their physicochemical properties, like viscosity, density, hydrophobicity, solubility, polarity, etc., can be effectively tuned for desired applications just by tuning the structures of cations and/or anions. Further, these designer solvents show dual behavior, i.e., electrolytes and solvents. In the last two decades, these unique materials have shown tremendous application potential in various interdisciplinary research areas, such as synthesis, catalysis, separation, extraction, nanoscience, and pharmaceutics, among many others. Further, the formation of surfactant self-assembled nanostructures (micelles and microemulsions (ME)) within ionic liquid-based systems of immense importance due to the vast utility of these nanostructures well as ILs in various fields of science and technology. These microheterogeneous systems can be effectively used as greener alternatives to those environmentally harmful volatile organic solvents which are largely used for academic and industrial research purposes.atile organic solvents which are largely used for academic and industrial research purposes. The IL-based self-assembled nanostructures show major advantages due to their affinity to solubilize many chemical and biochemical solutes (both hydrophilic as well as hydrophobic), thereby expanding their potential application as solubilizing media, media for synthesis, catalysis and biocatalysis, separation and extraction, drug delivery vehicles, and media for biochemical stability (e.g., protein and enzyme stability). This book chapter will highlight the formation and utility of various types of self-assembled nanostructures formed by surfactants, polymers, etc., within Ils-based media.
Sensing Applications of Ionic Liquids
Authors: Sandhu Navjot , Sehrawat Suvidha , Singh Atul Pratap
Published: July 2023

The Molten salts having melting points near to or less than room temperature is termed ionic liquids (ILs). A full IL unit generally comprises two oppositely charged ions with a remarkable size difference, i.e., bulky cation and comparatively small anion. The ILs are also labelled as future solvents due to their design flexibility and greener approach. Owing to their large number of favourable characteristics, such as less toxicity, good solvating capacity, high conductivity, nonvolatility, super sensitivity, selectivity and electrochemical stability, these ILs have provided a broader range of applicability in the field of sensing. ILs are proven to be of good use in the area of sensors as well as biosensors, i.e., optical sensing, thermometric sensing, electrochemical sensing and fluorescent sensing, etc. The ILs can be tailored by changing cations and anions as per the demand of the applications. In the present chapter, various aspects of ILs, including the use of these ILs in various sensing applications, have been explored and summed up to present an organized view for the researcher community as well as general readers.

Knowing that the insufficiency of these instruments to cover the daily risks incurred by individuals, created the need to devise new ways to protect resources, we problematize the role played by maritime insurance, seeking to capture (i) the regulatory norms to which they were subject, (ii) the traits that brought them closer to/distant from other instruments used for risk sharing and (iii) the criteria gradually used to evaluate the price to be paid for the risks experienced.
The Use of Discourse Markers in narrative by Chinese speakers of L2 European Portuguese
Authors: He Liuyang , Li Qinxue , Yang Aoran
Published: July 2023

In an attempt to examine the use of discourse makers by Chinese speakers of Second Language (L2) European Portuguese (EP) in oral narrative production, the current study is oriented by two research questions: (1) how is the frequency, distribution and variety of the discourse makers used by Chinese speakers of L2 EP? (2) is L2 proficiency level a potential factor that affects the use of discourse markers in narrative? On the basis of quantitative and qualitative analysis on the empirical data collected from 13 Chinese learners of EP, the results reveal that learners at a higher L2 level tend to produce more discourse markers in narrative, especially the structuring discourse markers. However, when it comes to the variety and distribution of this linguistic term, it seems that the richness of discourse markers does not correlate positively with L2 level and that almost all these expressions occur in the sentence-initial position
O Governador Ferreira do Amaral e Zhiliang Uma reflexão sobre heróis criados em Macau, a partir de experiência pedagógica com alunos chineses
Authors: Mourão Alda
Published: July 2023

This paper is the result of a pedagogical experience, carried out with Chinese students of Portuguese History. By approaching the theme of nineteenth-century Liberalism, we analyze the new political situation resulting from the outcome of the civil war, in 1834, namely the relationship between the Government of Lisbon and its eastern colony. In this context, Macau assumed administrative autonomy from 1848 onwards. We identified well-known personalities in Macau, but not in Portuguese historiography: João Maria Ferreira do Amaral and “Mi Shen, known as Zhiliang”. Amaral became Governor of Macao (1846), in a period of upheaval that was more affected in the region of the Pearl River and in China, with the outcome of the first Opium War (1842). Amaral's political activities explain his assassination by Zhiliang (1849). Two heroes were born simultaneously: the victim and the vigilante. Our study focused on the speeches that were produced about both heroes, in Portuguese and Chinese.

The docking of the piperlongumine molecule and its derivatives has been carried out to find molecules that have the potential as anti-cancer. A total of 18 ligands were docked to the 2v5z protein using the autodock4 and autodock vina programs. The binding energies of piperlongumine and piperlongumine derivatives [R1 = CH3 and R2 = H] were -8.6 kcal/mol and -9.3 kcal/mol, respectively. Based on molecular dynamics simulations, the hydrogen bond interaction fraction was dominated by GLN 206 residue in both the SAG (88%)  and piperlongumine derivatives ((R1=CH3, R2 = H)(93%) ligand, for this reason, this piperlongumine derivative molecule is predicted to have potential as MAO B inhibitor.

Background

Video and computer games are popular activities, with 72% of adolescents aged 13 to 17 years reporting video game use on either a computer, game console, or portable device. Despite high levels of video and computer game use in adolescence, relatively little scientific literature exists examining the association and effects of video and computer games on adolescents.

Objective

The objective of this study was to examine the prevalence of video and computer game use among US adolescents and rates of positive screens for obesity, diabetes, high blood pressure (BP), and high cholesterol.

Methods

A secondary data analysis was conducted using the National Longitudinal Study of Adolescent to Adult Health (Add Health) data, including adolescents aged 12 to 19 years between 1994 and 2018.

Results

Respondents (n=4190) who played the most video and computer games had a significantly (P=.02) higher BMI and were more likely to self-report having at least one of the evaluated metabolic disorders: obesity (BMI >30 kg/m2), diabetes, high BP (BP >140/90), and high cholesterol (>240). With increased video or computer game use, there was a statistically significant increase in high BP rates in each quartile, with those with more frequent use also having higher rates of high BP. A similar trend was observed for diabetes, though the association did not reach statistical significance. No significant association was observed between video or computer game use and diagnoses of dyslipidemia, eating disorders, or depression.

Conclusions

Frequency of video and computer game use is associated with obesity, diabetes, high BP, and high cholesterol in adolescents aged 12 to 19 years. Adolescents who play the most video and computer games have a significantly higher BMI. They are more likely to have at least one of the evaluated metabolic disorders: diabetes, high BP, or high cholesterol. Public health interventions designed to target modifiable disease states through health promotion and self-management may support the health of adolescents aged 12 to 19 years. Video and computer games can integrate health promotion interventions in gameplay. This is an important area for future research as video and computer games are integrated into the lives of adolescents.

Published: July 2023

BACKGROUND

Despite immense progress in artificial intelligence (AI) models, there has been limited deployment in health care environments. The gap between potential and actual AI applications is likely due to the lack of translatability between controlled research environments (where these models are developed) and clinical environments for which the AI tools are ultimately intended.

OBJECTIVE

We previously developed the Translational Evaluation of Healthcare AI (TEHAI) framework to assess the translational value of AI models and to support successful transition to health care environments. In this study, we applied the TEHAI framework to the COVID-19 literature in order to assess how well translational topics are covered.

METHODS

A systematic literature search for COVID-19 AI studies published between December 2019 and December 2020 resulted in 3830 records. A subset of 102 (2.7%) papers that passed the inclusion criteria was sampled for full review. The papers were assessed for translational value and descriptive data collected by 9 reviewers (each study was assessed by 2 reviewers). Evaluation scores and extracted data were compared by a third reviewer for resolution of discrepancies. The review process was conducted on the Covidence software platform.

RESULTS

We observed a significant trend for studies to attain high scores for technical capability but low scores for the areas essential for clinical translatability. Specific questions regarding external model validation, safety, nonmaleficence, and service adoption received failed scores in most studies.

CONCLUSIONS

Using TEHAI, we identified notable gaps in how well translational topics of AI models are covered in the COVID-19 clinical sphere. These gaps in areas crucial for clinical translatability could, and should, be considered already at the model development stage to increase translatability into real COVID-19 health care environments.
User-Centered Development of Bolster, an mHealth Intervention for Early Psychosis Caregivers: Needs Assessment, Prototyping, and Field Trial (Preprint)
Authors: Buck Benjamin , Wingerson Mary , Whiting Erica , Snyder Jaime , Monroe-DeVita Maria , Ben-Zeev Dror
Published: July 2023

BACKGROUND

Caregivers play a critical role in the treatment and recovery of youth and young adults at risk for psychosis. Caregivers often report feeling isolated, overwhelmed, and lacking in resources. Mobile health (mHealth) has the potential to provide scalable, accessible, and in-the-moment support to caregivers. To date, few if any mHealth resources have been developed specifically for this population.

OBJECTIVE

The aim of this study was to conduct user-centered design and testing of an mHealth intervention to support early psychosis caregivers.

METHODS

We conducted a multiphase user-centered development process to develop the Bolster mobile app. In phase 1, a total of 21 caregivers were recruited to participate in a qualitative needs assessment and respond to an initial prototype of the Bolster platform. Content analysis was used to identify key needs and design objectives, which guided the development of the Bolster mobile app. In phase 2, a total of 11 caregivers were recruited to participate in a 1-week field trial wherein they provided qualitative and quantitative feedback regarding the usability and acceptability of Bolster; in addition, they provided baseline and posttest assessments of the measures of distress, illness appraisals, and family communication.

RESULTS

In phase 1, participants identified psychoeducation, communication coaching, a guide to seeking services, and support for coping as areas to address. Live prototype interaction sessions led to multiple design objectives, including ensuring that messages from the platform were actionable and tailored to the caregiver experience, delivering messages in multiple modalities (eg, video and text), and eliminating a messaging-style interface. These conclusions were used to develop the final version of Bolster tested in the field trial. In phase 2, of the 11 caregivers, 10 (91%) reported that they would use Bolster if they had access to it and would recommend it to another caregiver. They also reported marked changes in their appraisals of illness (Cohen d=0.55-0.68), distress (Cohen d=1.77), and expressed emotion (Cohen d=0.52).

CONCLUSIONS

To our knowledge, this study is the first to design an mHealth intervention specifically for early psychosis caregivers. Preliminary data suggest that Bolster is usable, acceptable, and promising to improve key targets and outcomes. A future fully powered clinical trial will help determine whether mHealth can reduce caregiver burdens and increase engagement in services among individuals affected by psychosis.

Background. Chronic tonsillitis is the most common disease among children and adolescents in the structure of pathology of the ENT organs. Untimely diagnosis and irrational treatment lead to decompensation of chronic tonsillitis and the development of lesions of many organs and systems of the child’s body of tonsillogenic origin. The aim of the work was to study the clinical features and ultrasound changes of the palatine tonsils in adolescents with chronic tonsillitis. Materials and methods. We have examined 47 children aged 13 to 17 years suffering from chronic tonsillitis: group I — 27 patients with compensated chronic tonsillitis, group II — 20 patients suffering from decompensated chronic tonsillitis. The control group consisted of 16 practically healthy children, representative in terms of age and gender. We used clinical methods, ultrasonography of the palatine tonsils, and statistical methods. The study was approved by the Institutional Bioethics Committee and it conforms to the principles outlined in the Declaration of Helsinki. Results. According to the results of an ultrasound examination of the palatine tonsils in children with chronic tonsillitis, the main changes were an increase in their transverse dimensions by more than 15 mm, deepening of lacunae, thickening of the capsule, fibrous changes. In addition, in patients with tonsillogenic lesions of the cardiovascular system and a decompensated form of chronic tonsillitis, the pathological signs of the disease according to ultrasound were more significant and were manifested by unclear contours, increased echogenicity, heterogeneous hyperechoic structure, diffuse fibrous and cystic changes of the palatine tonsils. Conclusions. Ultrasonography of the palatine tonsils is a non-invasive, painless, accessible and informative method for studying the structure of the tonsils in normal and pathological conditions. It allows for a more thorough assessment of their changes in compensated and decompensated forms of chronic tonsillitis.
