Ethological characteristics of the primary depressive episode
Authors: Khomitskyi M. , Makoid V.
Published: June 2022

Significant polymorphism of the clinical picture of depression and certain contradictions of scientific views on the nosological specificity of these conditions complicate the establishment of specific clinical and psychopathological signs of endogenous and psychogenic depression, their typology, dynamics, prognosis, which makes the study of nonverbal behavior relevant and promising task. The purpose of the study was to establish the psychopathological and clinical-ethological manifestations of the primary depressive episode and to conduct a comparative analysis of endogenous and psychogenic variants of the primary depressive episode.  Contingents and methods. Based on the principles of bioethics, 96 patients (49 men and 47 women) with primary depressive episode – main group – who applied for outpatient psychiatric department of Zaporizhzhia regional psychiatry clinic in 2018-2021 were clinically examined. Diagnostic conclusions were made in accordance with the ICD-10 criteria. The control group consisted of 35 mentally healthy individuals, comparable in age and gender composition with the study group. Results. Patients with mild and moderate severity of the primary depressive episode are characterized by sad look, poses of reflection, submission, concentration in combination with facial expressions of suffering, guilt, helplessness, pensiveness, sideways, wrinkles on the forehead, stereotyped hand movements, head, head, reducing the synchronicity of gestural, facial and motor components of motility; avoidance of contacts and a sharp decrease in reactions to external influences. Severe manifestations of depression are characterized by sad and mournful facial expressions, lowered corners of the mouth, quiet voice, motor retardation, facial expressions of suffering, guilt and shame. Conclusion. The ethological component of the clinical-psychopathological method, based on the description of nonverbal behavior, can significantly improve the diagnostic capabilities of early detection of depressive episode, provides additional tools for typological differentiation and severity of patients with primary depressive episode.
Cultivating a Leadership Pipeline: Using a Real Options Lens to Understand Executives’ Strategic Staffing Decisions
Authors: Campion Michael C. , Campion Emily D. , Campion Michael A. , Bauer Talya N.
Published: June 2022

This paper adapts real options theory to explain how executives create and maintain real options portfolios within leadership pipelines. Hypotheses flowing from our theorizing predict that executives often make seemingly risky staffing decisions for leaders who occupy stepping-stone positions. Focusing on their option (future potential) rather than project (current productivity) value, executives laterally transfer leaders in stepping-stone positions frequently, despite it resulting in lower short-term job performance, but often promote these leaders at lower levels of performance and sooner. Once leaders are promoted to destination positions where they may stay indefinitely, executives tend to transfer high-performing leaders more often but not when they are still improving the effectiveness of their current unit. We present evidence suggesting that executives make these decisions to improve other units and maintain a flexible system, possibly recapturing previous investments in developing those leaders. We provide empirical support for our hypotheses using eight years of data in a large retail organization (n = 25,004) where executives overseeing thousands of units made internal mobility decisions. These findings refine real options theory, show that it explains these phenomena better than existing theories, and provide important and immediately usable practical implications for executives.

Authors: Fenesan Stephanie , Madan Bella , Nizarali Najla
Published: June 2022

Emicizumab is a new medication used in the treatment of people with haemophilia A and there is little in the current literature providing guidance for dental treatment. It is important to risk assess dental procedures appropriately according to their bleeding risk and to liaise closely with the patient's haematology team. This article provides an overview of emicizumab, its mechanism of action and implications for dental treatment, as well as examples of surgical management plans provided by the haemophilia team.

CPD/Clinical Relevance: It is important to liaise closely with the patient's haemophilia team to ensure provision of safe dental treatment.
Management of molar–incisor hypomineralization and hypodontia in monozygotic twins: a case report
Authors: Joshi Nikita , Mcloughlin Claire
Published: June 2022

Molar–incisor hypomineralization (MIH) is the hypomineralization of permanent first molars and is often associated with similarly affected incisors. This can lead to caries development and post-eruptive enamel breakdown. Early diagnosis and management are of prime importance to prevent premature loss of these molars at a young age, and to mitigate against negative changes on the patient's quality of life. This is particularly true when the patients also present with hypodontia. Wherever possible, conservative management in primary care should be undertaken. This case report explores the presentation and on-going treatment of MIH, and hypodontia, illustrated in monozygotic twin males.

CPD/Clinical Relevance: It is important to consider factors involved in the early identification of MIH and hypodontia and to develop strategies to treat the patient.

Published: June 2022

Abstract. Shah SB, Sharma HP. 2022. Bird diversity and factors affecting bird abundance at Dullu Municipality, Dailekh, Nepal. Biodiversitas 23: 1535-1545. Bird distribution, diversity, and abundance in any ecosystem are determined by seasonality, disturbances, and availability of resources. The point count method was used for bird surveys during the winter and summer season to identify the bird diversity and factors affecting bird abundance in 2020 at Dailekh District, Nepal. Altogether 98 bird species belonging to 11 orders and 38 families were recorded. The highest species richness was found for order Passeriformes and Muscicapidae family. Among recorded species, the higher species richness of birds was found during winter than summer season, and 52 bird species were observed at both seasons. These birds were more evenly distributed in summer than in the winter season. Among 98 species, the higher bird species were resident (91%), followed by winter migrants (7%), and remaining 2% of birds were summer and passage migrants. Himalayan Vulture (Gyps himalayensis Hume, 1869) and Alexandrine Parakeet (Palaeornis eupatria Linnaeus, 1766) were near threatened species found in the study area. Forest habitats had more diverse bird species than agricultural land. Different environmental parameters such as nearest distance to the water source, canopy cover, and nearest distance to forest habitat significantly affected bird occurrences. The species richness was positively correlated with the nearest distance to agricultural land for both seasons; however, it decreased with increasing distance to water source and canopy cover. In the study area, migratory, residential, endemic, and threatened bird species indicated the uniqueness of the bird habitat in the area; therefore, a site-specific management plan is necessary to conserve these bird species.

Abstract. Rizal S, Kustyawati ME, Suharyono AS, Suyarto VA. 2022. Changes of nutritional composition of tempeh during fermentation with the addition of Saccharomyces cerevisiae. Biodiversitas 23: 1553-1559. This study aimed to determine the effect of the addition of Saccharomyces cerevisiae on changes in nutritional composition during tempeh fermentation. The study used a Completely Randomized Block Design with two treatments and two replications. The first treatment was the type of tempeh inoculum with 4 levels, namely 0.2% commercial inoculum (Raprima), 1% Rhizopus oligosporus inoculum, 1% S. cerevisiae inoculum, and a mixture of 1% R. oligosporus inoculum, and 1% S. cerevisiae inoculum. The second treatment was the length of fermentation with 4 levels, namely 0 hours, 15 hours, 30 hours, and 45 hours. Observation parameters include fat, protein, ash, moisture, carbohydrates, and ?-glucan content during fermentation of tempeh. The data obtained were analyzed statistically using the Barlett and Tukey test then continued with the ANOVA test and the Orthogonal Polynomial-Orthogonal Comparison (OP-OC) test at the 5% level. The results showed that the addition of S. cerevisiae as an inoculum in making tempeh had an effect on changes in nutritional content during tempeh fermentation. The fat content, ash content, and moisture content of tempeh increased during fermentation, while the fat content and carbohydrate content decreased. The addition of 1% S. cerevisiae to tempeh fermentation by 1% R. oligosporus at 45 hours of fermentation resulted in the best nutritional content of tempeh with 17.40% protein content, 8.23% fat content, 65.74% moisture content, 1.33 ash content, 7.30% carbohydrate content, and 0.13% ?-glucan content.

Abstract. Abadi AL, Choliq FA, Oktavianita M, Arinata N, Hadi MS, Setiawan Y. 2022. Screening of soil fungi as bioremediation fungicide and its effect on growth of potato plants. Biodiversitas 23: 1605-1610. The negative impact of using fungicides on the environment can lead to chemical residues in the soil. The chemical degradation process can be carried out in several ways, one of which is by biological means by using microbes such as soil fungi. This study aimed to evaluate soil fungi isolated from natural forests for bioremediation of Mancozeb fungicide commonly used in potato fields in Indonesia. Isolated soil fungi were identified based on morphological and molecular level (PCR). The inhibition assay was carried out by growing fungal isolates on PDA media containing a fungicide with an active ingredient of 80% Mancozeb. Trichoderma harzianum isolated as a soil fungus from natural forest could grow in the fungicide Mancozeb medium. The biodegradation assay showed that treatment of Trichoderma harzianum and Mancozeb fungicide did not inhibit the growth of potato plants (plant height, number of leaves, and root length) as compared to the control. Based on the results of degradation test using HPLC method, T. harzianum both isolates can reduce the residue of fungicide Mancozeb in soil during the vegetative growth period of potato plants.
Uncertainty quantification in the analysis of liquefied soil response through Fuzzy Finite Element method
Authors: Kalateh Farhoud
Published: June 2022

In the present study, a scheme based on fuzzy finite element method was provided for uncertainty quantification of liquefied saturated soil response under dynamic loading. In this respect, the coupled dynamic equations which are known as u-p equations were used, and instead of crisp values for input parameters, including permeability coefficient, specific mass of the soil, compressibility and shear modulus, their fuzzy numbers were used. At the end, displacements and pore water pressure created during earthquake were reported as fuzzy numbers. After verifying procedures of fuzzy analysis by experimental results from the centrifuge model test No. 1 from the VELACS project, several membership grades were considered. Firstly, the effect of fuzzification of each input soil parameter investigated individually, and then effect of considering all four input soil parameters as fuzzy numbers was analyzed by developed method. It was indicated that results of the analysis during the effective time of the earthquake were strongly influenced by the shear modulus and partially by compressibility modulus, and after this time, it was mainly affected by the permeability coefficient. Also considering uncertainty nature of specific mass of the soil had no significant effect on the results.
The Language of Migration

Published: June 2022

Words are a dangerous game. They don’t just describe a reality; they also create it. At the same time, words are one of the most powerful tools we have at our disposal to change dominant, dehumanising, migratory narratives. This piece was inspired by a conversation between MIDEQ colleagues in the early stages of thinking and writing for this volume. During the conversation it became clear that whilst we appeared to be talking about the same thing, in reality, we weren’t. For each of us, the language of migration reflects our own experiences and engagement with the concept of “migration.” It reflects our understanding of what it means to “migrate” and who is viewed, understood, or represented as “a migrant.” These understandings, individual and collective, are shaped by our personal experiences and those of our family and friends, our engagement with the “scholarly literature” on migration from a range of disciplinary perspectives, our work and play as writers, artists, linguists, advocates and campaigners, doers and thinkers. These understandings are formed at the intersection of our complex and interwoven identities. Our conversation revealed the many ways in which the core ideas of “migration” and “migrants” are conceptualised in the various languages spoken, known or used by those working in or otherwise associated with, the MIDEQ Hub. Several contributors mentioned that in the contexts where they live and work, the word “migration” has a very different meaning – or no meaning at all. And that even within countries, different groups use the term “migrant” or “traveller” or “foreigner” to mean many different things, both positive and negative. The significance of this and the potential implications for the work are both exciting and challenging. When we write for a particular journal or audience, we often default to the dominant ways of representing migration linguistically without stopping to consider whether these meanings are the same for others. This piece is the product of that original conversation and our subsequent engagements, woven together in ways that we hope provide a meaningful starting point for better understanding of the multiple meanings and significances of “migration,” as used in this volume.

As we live in industry 4.0, digital communication has become the most accessible one. One of the examples of digital communication is Instagram. Instagram is one of the most famous among youths all over the world. It is used as a means of storing photos and videos and as a means of conveying meaning. The images displayed on Instagram attract the readers to understand the meaning attached in the image or behind it implicitly. At that point, the purpose of this study is to decipher and analyze the peace message contained in Morshad Mishu's Instagram image for The Global Happiness Challenge. This Instagram account describes wars all over the world, with a focus on Islamic countries. Images of war on Instagram are presented in two styles: black-white and colourful design. The significance of this research is to communicate and convey the message of peace in the digital era through Instagram as one of the long-term goals of all campaigns to achieve a better life. The study employs a descriptive qualitative approach. Roland Barthes' semiotic theory is applied to the reading of seven images. They are three stages of the analysis: (1) denotation meaning, (2) connotation meaning, and (3) myths. The main finding reveals from reading the seven images in The Global Happiness Challenge Instagram is that the meaning of peace in seven images is used as a bargaining power to end the war. Only tears, sadness, fear, death, and destruction have resulted from the war.

Published: June 2022

To meet the need for rapid, high-precision, and non-contact measurement of the radius of curvature (ROC) for large quantities of spherical optics, a radius measurement method based on transverse dual differential confocal (TDDC) detection is proposed in this study. First, a template S0 with a known ROC, R 0, is axially scanned on its confocal position to obtain the fitted linear function lTDDC(z) using TDDC. Second, the template S0 is replaced by S
n
, which is one of the test sample in large quantities, then the single point TDDC intensity ITDDC(Δzn) is captured without scan, which will be applied to obtain the defocus Δzn according to the linear function lTDDC(z). Finally, the ROC Rn under test is calculated using Δzn and R 0. Simulation and experiments show that the measurement accuracy can achieve 8.0 ppm, and the measurement efficiency is 60 times higher than that of the traditional differential confocal scanning measurement. Measurement based on TDDC only requires scanning once and replacing Sn N times to realize the fast, high-precision, non-contact ROC detection of N pieces of spherical optics, which enables the high-efficiency and high-precision measurement of large quantities of spherical optics.
pHSCNN: CNN-based hyperspectral recovery from a pair of RGB images
Authors: Sun Yuanyuan , Zhang Junchao , Liang Rongguang
Published: June 2022

To increase the fidelity of hyperspectral recovery from RGB images, we propose a pairwise-image-based hyperspectral convolutional neural network (pHSCNN) to recover hyperspectral images from a pair of RGB images, obtained by the same color sensor with and without an optical filter in front of the imaging lens. The proposed method avoids the pitfall of requiring multiple color sensors to obtain different RGB images and achieves higher accuracy than recovery from single RGB image. Besides, pHSCNN can also optimize the optical filter to further improve the performance. To experiment on real data, we built a dual-camera hyperspectral imaging system and created a real-captured hyperspectral-RGB dataset. Experimental results demonstrate the superiority of pHSCNN with the highest accuracy of the recovered hyperspectral signature perceptually and numerically.

Published: June 2022

We demonstrate a fiber-based optical vortex beam source operating in broadband or tunable mode in the spectral range of 1100–1400 nm. The vector vortices of the total angular momenta equal to +2, 0, and −2 are obtained by converting the respective linearly polarized (LP11) modes of the two-mode birefringent PANDA fiber with stress-applying elements by gradually twisting its output section. At the input end, the PANDA fiber is powered by broadband supercontinuum or tunable Raman solitons generated in the LP11 polarization modes of a birefringent microstructured fiber with a specially designed dispersion profile and coupled to the respective LP11 modes of the PANDA fiber. Two pulse lasers operating in different regimes (1 ns/1064 nm and 190 fs/1037 nm) were used as the pump to generate supercontinuum or tunable solitons directly in the LP11 modes of the microstructured fiber purely excited with a special Wollaston prism-based method. The high modal and polarization purities of the beams after successive transformations were experimentally confirmed. We also proved the vortex nature of the output beams using shearing interferometry.

Published: June 2022

Background

Regimen simplification to 2-drug antiretroviral therapy (2-ART) may address potential tolerability issues, increase adherence, and reduce toxicity and potential drug-drug-interactions among people living with HIV-1 (PLWH). However, real-world treatment patterns and characteristics of 2-ART users are unclear.

Methods

This retrospective observational cohort study employed a large-scale medical claim database of Japanese hospitals to extract data on 4,293 PLWH aged ≥18 years with diagnosis of HIV and treated with any ART regimens between April 2008 and April 2019. A 2-ART cohort was compared with a 3-drug antiretroviral therapy (3-ART) cohort in terms of population characteristics, comorbid conditions, and treatment patterns. Treatment switching rates were calculated for each cohort followed by sensitivity analysis to confirm the robustness of the findings.

Results

There were 94 individuals identified in the 2-ART cohort. Compared to the standard 3-ART cohort (n = 3,993), the 2-ART cohort was older (median age 53 [IQR 44–64] vs 42 years [IQR 35–50]), with a lower proportion of males (87.2% vs 93.8%), higher Charlson Comorbidity Index (CCI) (median score 6 [IQR 5–8] vs 5 [IQR 4–6]), more co-medications (median 6 [IQR 4–11] vs 3 [IQR 2–7]), and a higher percentage of AIDS-defining conditions (66.0% vs 42.8%). The most common 2-ART were protease inhibitor (PI) + integrase strand transfer inhibitor (INSTI) and non-nucleoside reverse transcriptase inhibitor (NNRTI) + INSTI (33.0% and 31.9%, respectively). Overall, most of the regimens were nucleoside reverse transcriptase inhibitor (NRTI)-sparing (71.3%), with a decreasing trend over time (76.2% to 70.2%). ART regimen switch occurred more often in the 2-ART cohort than in the 3-ART cohort (33.0% vs 21.2%).

Conclusion

The profiles of individuals on 2-ART in Japan were demonstrated to be complex. Most were treated with NRTI-sparing regimens which may reflect an effort to reduce treatment-related toxicities.
The prevalence of mild cognitive impairment by aspects of social isolation
Authors: Ishikawa Kyle Masato , Davis James , Chen John J. , Lim Eunjung
Published: June 2022

Objectives

This study describes the prevalence of mild cognitive impairment (MCI) across different aspects of social isolation among adults 65 years or older.

Methods

In this cross-sectional study, we utilized the Wave 3 data from the National Social Life, Health, and Aging Project (NSHAP). MCI was defined as a Montreal Cognitive Assessment (MoCA) score less than 23. Prevalence of MCI was calculated for above and below average social disconnectedness (SD), perceived isolation (PI), and demographic variables age, gender, race/ethnicity, education, and household income.

Results

The overall prevalence [and 95% confidence interval] of MCI was 27.5% [25.5–29.6]. The high prevalence of MCI was found in those who had above average SD (32.0% [29.1–34.9]), above average PI (33.3% [29.7–36.8]), were older in age (43.1% [38.9–47.3]), male (28.7% [25.9–31.5]), Black (61.1% [52.5–69.6]), had less than a high school education (66.3% [58.9–73.8]), or were in the lowest income group (46.2% [39.7–52.7]). Those with above average SD or PI had a higher prevalence of MCI in almost all demographics, compared to those with below average SD or PI. Those who were Black or African American or had less than a high school education did not have a greater prevalence of MCI when SD was above average.

Discussion

This current study adds to the body of literature that links SD and PI to MCI and sheds light on the possible existing socio-demographic disparities. Groups with greater than average SD or PI tend to have a higher prevalence of MCI. Further studies are needed to establish a causal association of SD and PI with MCI.
Dynamical intervention planning against COVID-19-like epidemics
Authors: Oliva Gabriele , Schlueter Martin , Munetomo Masaharu , Scala Antonio
Published: June 2022

COVID-19 has got us to face a new situation where, for the lack of ready-to-use vaccines, it is necessary to support vaccination with complex non-pharmaceutical strategies. In this paper, we provide a novel Mixed Integer Nonlinear Programming formulation for fine-grained optimal intervention planning (i.e., at the level of the single day) against newborn epidemics like COVID-19, where a modified SIR model accounting for heterogeneous population classes, social distancing and several types of vaccines (each with its efficacy and delayed effects), allows us to plan an optimal mixed strategy (both pharmaceutical and non-pharmaceutical) that takes into account both the vaccine availability in limited batches at selected time instants and the need for second doses while keeping hospitalizations and intensive care occupancy below a threshold and requiring that new infections die out at the end of the planning horizon. In order to show the effectiveness of the proposed formulation, we analyze a case study for Italy with realistic parameters.
Fan fashion of multiple fandoms: An exploration of female science-fiction and fantasy fans’ dress practices
Authors: Smith Dina , Stannard Casey , Kuttruff Jenna Tedrick
Published: June 2022

The purpose of this research was to explore the dress practices of females who wear fan fashion connected to multiple sci-fi/fantasy fandoms in a variety of everyday social contexts. Data from semi-structured, online interviews were analysed in relation to identity theory and the concept of appearance labour using NVivo qualitative analysis software and the constant comparison method. While the data revealed general motivations for wearing fan fashion, it also showed that participants expressed their fan identity across formal, semi-formal and professional settings through wearing fan fashion. Participants also alleviated appearance labour by carefully choosing specific types of fan fashion appropriate for certain social settings and audiences (i.e. conspicuous vs. inconspicuous). This research provided more insight into the trend of fan fashion and led to the development of a taxonomy in which types of fan fashion are classified in terms of their conspicuousness.

Tiempo futuro: la potencialidad de la literatura ecuatoriana frente al canon
Authors: Mayorga Gutiérrez Esteban
Published: June 2022

Este ensayo plantea que una de las propiedades literarias latinoamericanas, y ecuatorianas, de mayor influencia, es aquella tocante al tiempo visto en su relación a la tradición. El control y la monopolización jerárquica de la temporalidad necesita desplazar su mirada hacia la futuridad para diseñar diferencias en la matriz política, nacional y estética que no sean identificables con el poder de siempre. La metodología proviene de la noción de la futurabilidad (Berardi), dentro de la discusión formulada desde las ficciones fundacionales de América Latina, atada a aquella de la modernidad que se designa a través del paso del tiempo (Latour), y que permite entender cómo la literatura de América Latina, al verse permeada por el rango temporal, puede potenciarse hacia el devenir. Escribe Rancière que dentro de la distribución de lo sensible se encuentran categorías de tiempo que le son cruciales al pensar de la literatura (9-10). El presente permite o prohíbe un tipo de futuro y en este ejercicio establece de forma arbitraria una jerarquía de textos, haciéndonos creer quetenemos una necesidad de obras maestras. Nuestra tarea ética es resistirse al pasado e imaginarnos otro futuro, uno en el cual se reorganice esta idea de necesidad para redistribuir «los pesos en la balanza» (Rancière 26). Se mencionan, a la mitad del artículo, dos obras que prometen ceñirse a la posibilidad futura de torcer el canon ecuatoriano hacia un futurodeseable. Una de ellas, escrita por Salvador Izquierdo (1980) y la otra por Daniela Alcívar (1982). Asimismo, el objetivo de este estudio es reflexionar sobre uno de los modos perversos de operar de las literaturas nacionales en las literaturas pequeñas, como se considera a la literatura ecuatoriana, utilizando el formato del ensayo.
Más allá de la ley. Transitar y acceder a la universidad española con parálisis cerebral
Authors: Hinojosa Pareja Eva F. , Zamora Recio Estela , Ruiz Calzado Inmaculada
Published: June 2022

A pesar de los esfuerzos legislativos para facilitar la transición y el acceso a la educación superior de estudiantes con discapacidad, su traslación a la práctica se valora insuficiente, lo que requiere de nuevos desarrollos políticos y educativos sustentados en el impacto de las políticas en las personas y visibilizando las experiencias de este colectivo. Desde el marco teórico de la inclusión, este estudio se centra en conocer las experiencias y percepciones sobre transición y acceso a la universidad de 12 estudiantes con parálisis cerebral, colectivo ausente en la investigación en esta etapa. Mediante un enfoque biográfico-narrativo, concretado en autoinformes y entrevistas semiestructuradas, se analizan de manera emergente tres categorías: transición y actividades de iniciación, barreras y ayudas percibidas y concepciones sobre diversidad e inclusión. Los resultados destacan el papel de las familias en la transición y avances en cuanto a la disposición de ayudas materiales y de servicios específicos por parte de las instituciones, a la vez que subrayan barreras materiales y cuestionan la pertinencia de algunas de las acciones emprendidas. Estos hallazgos se encuentran atravesados por tres concepciones distintas de diversidad: naturalización, diferencia y desigualdad. Implicaciones a nivel científico y político son discutidas al término del artículo.

Authors: Palomer Music Macarena , Berger Correa Bárbara , Romero Rojas Víctor , Lizama Macaren
Published: June 2022

Introducción: vivir la sexualidad y afectividad de forma plena es fundamental en todo ser humano; sin embargo, las personas con síndrome de Down (SD) tienen escasas instancias de educación sexual y pocos espacios de socialización para experimentarla. Objetivos: describir el conocimiento que tienen jóvenes con SD sobre temáticas básicas de pubertad, relaciones de pareja y reproducción. Metodología: estudio cualitativo, descriptivo, exploratorio, en dos grupos focales de jóvenes con SD, entre 13 y 18 años, separados por género. La información fue grabada, transcrita y codificada según categorías emergentes. Resultados: sobre la palabra “sexualidad”, las mujeresdeclararon no haberla escuchado y los hombres hicieron referencia a “sexo”, “relaciones de pareja”, “amor” y “familia”. Para “cambios puberales”, ambos grupos señalaron los cambios más visibles, pero nada respecto a reproducción. Solo un participante entendía el concepto de “relación sexual”. Las mujeres consideraron el “inicio de la vida humana” como un evento de generación espontánea y los hombres plantearon una teoría fantasiosa. La familia fue la principal fuente de información. Discusión: los participantes mostraron un manejo deficiente e infantilizado de la información. Son urgentes la investigación y el desarrollo de programas de Educación Sexual y así dignificar la sexualidad y afectividad de personas con SD, desde un enfoque de derechos.

Las relaciones interpersonales influyen de forma significativa en la inclusión social durante los procesos de tránsito a la vida adulta de las personas con discapacidad intelectual. Disponer de una red social de apoyo se considera la cima de la inclusión social. Con el objetivo de explorar el papel de las relaciones de amistad en los procesos de vida independiente de las personas con discapacidad intelectual, así como el papel de los profesionales de apoyo, se han llevado a cabo grupos de discusión tanto con personas con discapacidad intelectual como con profesionales. Los resultados de este estudio muestran la visión que unos y otros tienen de la amistad, así como elpapel que consideran que desarrollan las amistades en los procesos de vida independientede las personas con discapacidad intelectual y el rol que desempeñan los profesionales de apoyo con relación a la promoción del establecimiento y mantenimiento de relaciones de amistad de las personas con discapacidad intelectual. Se considera necesario el diseño y desarrollo de acciones específicas que permitan a las personas con discapacidad identificar y/o ampliar su red natural de apoyo.

La sexualidad forma parte del desarrollo de todos los seres humanos, desafortunadamente una gran parte de las personas con discapacidad intelectual e incluso las personas con Trastorno del Espectro Autista (TEA) no reciben una atención necesaria referente a la salud sexual. El presente estudio tiene como finalidad comparar la comunicación sexual de los padres de acuerdo a los niveles de TEA de los hijos(as). Para ello, se utilizó un diseño de tipo descriptivo de corte transversal. La muestra fue conformada por 152 padres de hijos(as) con TEA, se utilizó el apartado de comunicación sexual del “Parenting and Child Sexuality Questionnaire” (Morawaska et al., 2015) para medir la comunicación sexual. Como resultado se encontró que la comunicación sexual entre padres e hijos(as) con TEA es muy general, donde los temas más complejos como el abuso sexual y embarazo no fueron abordados por los padres, además se encontraron diferencias significativas entre la comunicación sexual de los padres y los niveles de TEA de los hijos(as). En ese sentido, es importante que los profesionales de la salud alienten y apoyen a los padres en la práctica de la comunicación sexual con sus hijos con TEA.
La migración venezolana a Colombia y Perú
Authors: Sacristán-Rodríguez Claudia Patricia , Llanez Anaya Helmer Fernando
Published: June 2022

Este artículo cuestiona la evolución del grado de integración regional en lo atinente al tema migratorio y se establece que la gestión migratoria sigue estando en manos de los Estados Nacionales, lo cual permite reflexionar sobre la consolidación de la gobernanza regional migratoria (GRM) sobre la migración venezolana en Colombia y Perú, países asociados del acuerdo de residencia del MERCOSUR. La metodología de investigación utilizada es mixta: cualitativa y cuantitativa. El diseño de la investigación es exploratorio-analítico-descriptivo por tratarse de un tema con poco desarrollo. Se concluye que hay convergencia formal en la regulación migratoria alineada con la firma del acuerdo de residencia del MERCOSUR, sin embargo, tanto Colombia como Perú no aplicaron el acuerdo de residencia hasta 2021, sino que asumieron instrumentos jurídicos ad hoc, con lo cual la convergencia hacia una (GRM) es débil y se subraya la necesidad e importancia de la aplicación de una gobernanza de la migración regional.

Published: June 2022

This paper focuses on electric vehicles with dual motors combined with a planetary gear train. The combination of sun and ring motor allows for achieving higher efficiencies and satisfying power demands as compared to single motor powertrains. Primarily dual motor drive with planetary gear train is proposed and simulated with different drive cycles. Secondarily by extracting the motor efficiency maps working area of different modes, speed and efficiency are determined. Finally, an optimization algorithm was developed to automatically change speed and torque as per load demand. In this way, our work could represent a framework for improving efficiency performances and load demands of an electric vehicle.

Published: June 2022

Objectives

The aim of this study was to explore nursing faculty experiences in integrating digital tools to support undergraduate students’ learning and development of nursing informatics competencies.

Methods

This focused ethnography study used a combination of semi-structured interviews, document reviews, and field visits. Convenience and snowball sampling were applied to recruit participants. Data were analyzed concurrently with data collection, using thematic analysis.

Results

Twenty-one faculty members from nine undergraduate nursing programs in Western Canada participated. Themes discussed include: 1) meaning of the term nursing informatics, 2) faculty perceived nursing informatics competence, 3) developing students’ nursing informatics competencies, 4) facilitators, and 5) challenges.

Conclusions

Nursing faculty are relatively engaged in developing students’ informatics competencies. However, challenges must be addressed and faculty need more support to improve their own informatics capacity. Implications for Practice and Research: This study has implications for faculty, nursing program administrators, and nursing organizations.

Published: June 2022

Objective Traumatic brain injury (TBI) is associated with an increased risk of late neurodegenerative complications via unknown mechanisms. Circulating neurotoxic 5-hydroxytryptamine 2A receptor (5-HT2AR) autoantibodies were reported to increase in subsets of obese type 2 diabetes having microvascular complications. We tested whether 5-HT2AR autoantibodies increase in adults following traumatic brain injury in association with neurodegenerative complications. Methods Plasma from thirty-five middle-aged and older adult veterans (mean 65 years old) who had suffered traumatic brain injury was subjected to protein-A affinity chromatography. The resulting immunoglobulin (Ig) G fraction was tested for neurotoxicity (acute neurite retraction, and accelerated cell death) in mouse N2A neuroblastoma cells or for binding to a linear synthetic peptide corresponding to the second extracellular loopregion of the human 5-HT2A receptor. Results Nearly two-thirds of traumatic brain injured-patients harbored 5-HT2AR autoantibodies in their circulation. Active TBI autoantibodies caused neurite retraction in mouse N2A neuroblastoma cells and accelerated N2A cell loss which was substantially prevented by co-incubation with a two hundred and fifty nanomolar concentration of M100907, a highly selective 5-HT2AR antagonist. Antagonists of RhoA/Rho kinase and Gq11/ phospholipase C/inositol triphosphate receptor signaling pathways blocked TBI autoantibody-induced neurite retraction. Following traumatic brain injury, autoantibody binding to a 5-HT2A receptor peptide was significantly increased in patients having co-morbid Parkinson’s disease (n=3), dementia (n=5), and painful neuropathy (n=8) compared to TBI subsets without neurologic or microvascular complication (n=20). Autoantibody titer was significantly elevated in TBI subsets experiencing multiple neurotraumatic exposures vs. single TBI. Plasma white blood cell, a marker of systemic inflammation, correlated significantly (correlation coefficient r =0.52; P < 0.01) with, 5-HT2A receptor peptide binding of the TBIautoantibody. Conclusion These data suggest that circulating neurotoxic 5-hydroxytryptamine 2A receptor agonist autoantibodies increase in adults following traumatic brain injury in association with late neurodegenerative complications.

Published: June 2022

Aims The aim was to examine whether the Prognostic Nutritional Index (PNI) and Controlling Nutritional Status (CONUT) score are predictors of wound healing in patients with diabetic foot ulcers (DFUs). Materials and Methods This was a hospital-based, single-center, observational, longitudinal cohort study of 349 Japanese patients (84 women, 265 men; mean (standard deviation) age 62.8 (12.8) years) with DFUs. The endpoint was complete wound healing. The classical Cox proportional model and competing-risks model were used to calculate the hazard ratios (HRs) and the 95% confidence interval (CI) for reaching the endpoint. Results During a median (range) follow-up of 2.3 (0.03-62.3) months, 220 patients (63.0%) reached the endpoint. In the multivariate Cox proportional hazards model, higher PNI was identified as an independent predictor for the endpoint (HRs 1.22, 95% CI 1.01-1.48, p=0.038). In the multivariate competing-risks model analysis, both higher PNI (HRs 1.26, 95% CI 1.03-1.53, p=0.024) and lower CONUT score (HRs 0.80, 95% CI 0.65-0.99, p=0.045) were identified as independent predictors for the endpoint. Similar results were obtained when the PNI and the CONUT score were treated as categorical variables (≥ median or less). Conclusions Nutritional status, as assessed using the PNI and CONUT score, is a novel clinical predictor for wound healing in patients with DFUs.
