Being recovered: a qualitative study of parents’ experience of their child’s recovery up to a year after a displaced distal radius fracture
Authors: Phelps Emma E. , Tutton Elizabeth , Costa Matthew L. , Achten Juul , Gibson Phoebe , Moscrop Amy , Perry Daniel C.
Published: May 2024

Aims

The aim of this study was to explore parents’ experience of their child’s recovery, and their thoughts about their decision to enrol their child in a randomized controlled trial (RCT) of surgery versus non-surgical casting for a displaced distal radius fracture.

Methods

A total of 20 parents of children from 13 hospitals participating in the RCT took part in an interview five to 11 months after injury. Interviews were informed by phenomenology and analyzed using thematic analysis.

Results

Analysis of the findings identified the theme “being recovered”, which conveyed: 1) parents’ acceptance and belief that their child received the best treatment for them; 2) their memory of the psychological impact of the injury for their child; and 3) their pride in how their child coped with their cast and returned to activities. The process of recovery was underpinned by three elements of experience: accepting the treatment, supporting their child through challenges during recovery, and appreciating their child’s resilience. These findings extend our framework that highlights parents’ desire to protect their child during early recovery from injury, by making the right decision, worrying about recovery, and comforting their child.

Conclusion

By one year after injury, parents in both treatment groups considered their child “recovered”. They had overcome early concerns about healing, the appearance of the wrist, and coping after cast removal. Greater educational support for families during recovery would enable parents and their child to cope with the uncertainty of recovery, particularly addressing the loss of confidence, worry about reinjury, and the appearance of their wrist.

An Early Modern Audience in the Classroom: Metatheater, Religion, Race
Authors: Kimmel Seth
Published: May 2024

Abstract: Emphasizing the role of audiences in shaping the meaning and social function of performance, this essay presents some suggestions for deepening the discussion of race in our undergraduate classes on "Golden Age" theater. These suggestions include enticing students with recognizable names and accessible texts—Cervantes's El retablo de las maravillas is one of my choices—and then nudging them to consider canonical works in dialogue both with representations of Black characters and with the diasporic experience of free and enslaved Black people in Spain during the early modern period. We should encourage class discussion that draws early modern primary sources into the racial politics of the present. We should likewise investigate and historicize the relationship between religion and race as conceptual categories. These sorts of pedagogical adjustments are part of the effort to rethink the methodological presuppositions and canons that have long defined—and constrained—early modern Iberian studies.
In Translation: Gabriel Navarro, Latina/o Film Critic
Authors: Gunckel Colin , Serna Laura Isabel
Published: May 2024

ABSTRACT: Gabriel Navarro (1894–1950) was critic and entertainment editor for La Prensa (San Antonio) and La Opinión (Los Angeles) during the 1920s and 1930s. In an extensive body of film reviews, columns, and film-related fiction, Navarro considered questions of fandom, stardom, representation, and the racial hierarchies that structured the US film industry. He offered his readers behind-the-scenes accounts of Hollywood, advocated for Mexican immigrant audiences and talent, and argued for culturally sensitive representation. Navarro's work opens new ways of thinking about Latino/a/es in US film history and offers new perspectives on the historical relationships between mainstream media and marginalized audiences.

Published: May 2024

Addressing the capacity, low cost, and low power challenges of 6G distribution networks, this paper proposes and demonstrates a multi-band optical metro-access network architecture employing semiconductor optical amplifier (SOA)-based wavelength division multiplexing (WDM) switches as low-cost and low-power multi-band optical add-drop multiplexers (MB-OADMs) to extend the capacity beyond C-band limits. We implemented and evaluated the performance of an SOA-based MB-OADM prototype in the C- and O-bands including the network reconfigurability, the node scalability, and the capability to support high-capacity transmission. Experimental results show that the MB-OADM-based network maintains high optical signal-to-noise ratio (OSNR) values up to 35.38 dB in the C-band and 33.56 dB in the O-band over 100 km across five nodes with a 20 km linkspan in between (a total of 100 km) without additional optical amplifiers at 25 Gbps. This work also assesses the MB-OADM-based network scalability in terms of nodes and data rate. Results indicated that the architecture supports cascading through nine C-band nodes over 45 km with a 3.6 dB power penalty at 25 Gbps for a bit error rate (BER) of 10−6 and through four O-band nodes with a 3 dB penalty at 25 Gbps for a BER of 10−6, maintaining nearly uniform power levels across channels at a BER under the FEC threshold. It successfully demonstrates PAM-4 at 50 Gbps and 100 Gbps data rate transmission operation crossing four nodes over a 4 km distance, with 2 dB and 2.4 dB power penalty at a BER of 10−3 in the C-band and 1.85 dB and 2.2 dB power penalty at a BER of 10−3 in the O-band, respectively.
Robust polarimetric dehazing algorithm based on low-rank approximation and multiple virtual-exposure fusion
Authors: Zhou Yifu , Wei Hanyue , Liang Jian , Ma Feiya , Yang Rui , Ren Liyong , Li Xuelong
Published: May 2024

Polarimetric dehazing is an effective way to enhance the quality of images captured in foggy weather. However, images of essential polarization parameters are vulnerable to noise, and the brightness of dehazed images is usually unstable due to different environmental illuminations. These two weaknesses reveal that current polarimetric dehazing algorithms are not robust enough to deal with different scenarios. This paper proposes a novel, to our knowledge, and robust polarimetric dehazing algorithm to enhance the quality of hazy images, where a low-rank approximation method is used to obtain low-noise polarization parameter images. Besides, in order to improve the brightness stability of the dehazed image and thus keep the image have more details within the standard dynamic range, this study proposes a multiple virtual-exposure fusion (MVEF) scheme to process the dehazed image (usually having a high dynamic range) obtained through polarimetric dehazing. Comparative experiments show that the proposed dehazing algorithm is robust and effective, which can significantly improve overall quality of hazy images captured under different environments.
A refined approach for evaluating small datasets via binary classification using machine learning

Published: May 2024

Classical statistical analysis of data can be complemented or replaced with data analysis based on machine learning. However, in certain disciplines, such as education research, studies are frequently limited to small datasets, which raises several questions regarding biases and coincidentally positive results. In this study, we present a refined approach for evaluating the performance of a binary classification based on machine learning for small datasets. The approach includes a non-parametric permutation test as a method to quantify the probability of the results generalising to new data. Furthermore, we found that a repeated nested cross-validation is almost free of biases and yields reliable results that are only slightly dependent on chance. Considering the advantages of several evaluation metrics, we suggest a combination of more than one metric to train and evaluate machine learning classifiers. In the specific case that both classes are equally important, the Matthews correlation coefficient exhibits the lowest bias and chance for coincidentally good results. The results indicate that it is essential to avoid several biases when analysing small datasets using machine learning.
Modern models for predicting bankruptcy to detect early signals of business failure: Evidence from Montenegro
Authors: Vukčević Milica , Lakićević Milan , Melović Boban , Backović Tamara , Dudić Branislav
Published: May 2024

This paper explores predicting early signals of business failure using modern models for bankruptcy prediction. It reviews how continuous operations enhance market value, strengthening competitiveness and reputation among stakeholders. The study involves medium and large companies in the Montenegrin market from 2015 to 2020, comprising 30 bankrupt and 70 financially stable firms. Logistic regression is also employed to create a logit model for early detection of bankruptcy signals in companies. This research establishes the empirical validity of modern models in predicting business failure in the Montenegrin market, particularly through logistic regression. Significant indicators, such as the Degree of Indebtedness (DI) and turnover ratio of business assets (TR), exhibit strong predictive power with a p-value less than 0.001 according to Likelihood ratio tests. The paper underscores the potential benefits of bankruptcy prediction for both internal and external stakeholders, especially investors, in enhancing the competitiveness of Montenegro’s large and medium-sized companies. Notably, the research contributes by bridging the gap between theory and practice in Montenegro, as bankruptcy prediction models have not been extensively applied in the market. The authors suggest the possible applicability of the created logit model to neighboring countries with similar economic development levels. In that sense, the concept of predicting bankruptcy is positioned as integral to corporate strategy, impacting the overall reduction of bankruptcies. The paper concludes by highlighting its role as a foundation for future research, addressing the literature gap in the application of bankruptcy prediction models in Montenegro. The created logit model, tailored to the specific needs of Montenegrin companies, is presented as an original contribution, emphasizing its potential to strengthen the competitiveness of companies in the market.

Published: May 2024

Aim

Our first aim was to present norm values for the Preference for Solitude Scale by sex, age, and other sociodemographic groups. Our second aim was to evaluate the correlates of preference for solitude.

Methods

Data were collected in August/September 2023 from a sample of individuals (N = 5000) living in Germany aged 18 to 74 years (ensuring representativeness in terms of sex, age group and federal state for the German general adult population). The established and valid Preference for Solitude Scale (range 0 to 12, with higher values reflecting a stronger preference for solitude) was used to quantify the preference for solitude. Norm values were provided by sex and age groups. Multiple linear regressions were used to examine the correlates of preference for solitude.

Results

Average preference for solitude score was 7.6 (SD = 3.0; 0 to 12). The average score was 7.3 (SD = 3.0) among males and 7.9 (SD = 2.9) among females. Regressions showed that a stronger preference for solitude was associated with being female (β = .51, p < .001), being older (e.g., being 40 to 49 years compared to 18 to 29 years, β = .85, p < .001), being single (e.g., divorced compared to being single, β = -.78, p < .01), higher level of education (secondary education compared to primary education, β = .43, p < .01), never been a smoker (e.g., daily smoker compared to never smokers, β = -.61, p < .001), absence of alcohol consumption (e.g., drinking once a week compared to never drinking, β = -1.09, p < .001), no sports activity (e.g., 2–4 hours per week compared to no sports activity, β = -.60, p < .001), poorer self-rated health (β = .28, p < .001) and more depressive symptoms (β = .05, p < .001). Sex-stratified regressions yielded similar results.

Conclusion

Norm values provided in this study can be used as a benchmark for comparison with other countries and can guide further research dealing with preferences for solitude. We demonstrated the importance of several sociodemographic factors (e.g., marital status), lifestyle-related factors (e.g., sports activity), and health-related factors (e.g., depressive symptoms) for the preference for solitude. Such knowledge about the correlates of preference for solitude may help to characterize them. This is essential to ensure a good balance between social interaction and being alone. This is important because preference for solitude is associated with poor self-rated health and depression, but also with healthy behaviors such as abstaining from smoking and drinking
The circulation of a «fascist literature» in the italian democracy
Authors: Martini Andrea
Published: May 2024

In an article published in The Wiener Library Bulletin in 1951, the historian and former partisan Giorgio Vaccarino broached the subject of the “fascist literature” circulating in Italy. Three years later, the anti-fascist literary scholar Giuseppe Tramarollo revisited the question in La Voce Repubblicana, declaring the dissemination of texts with a clear fascist matrix to be a threat to Italian democracy. This essay seeks to shed light on this circulation, which has long been underestimated by historiography and was downplayed by the post-1945 fascist milieu, which sought to portray itself as being excluded from the political arena.
Without wishing to overstate the importance of fascist literature in the post-war period, this article aims to describe its characteristics while also highlighting the tolerance of the authorities and the complicity of the publishing market, which, by ignoring political or moral considerations, offered a platform to many fascist personalities.
Posfascismo en España
Authors: Muñoz Soro Javier
Published: May 2024

El concepto «posfascismo» no ha sido utilizado, en general, para referirse a la dictadura del general Franco en España tras la derrota de las potencias del Eje en 1945. Sin embargo, puede ayudar a definir y explicar mejor la compleja naturaleza del régimen político en esas tres décadas que van hasta la muerte del dictador en 1975, durante las cuales se superponen los procesos de cambio socioeconómico y la continuidad de las estructuras político-institucionales. En particular, permite enlazar la experiencia histórica del fascismo con la evolución de las derechas españolas y europeas en la segunda posguerra, desde el neofascismo a la extrema derecha, y con la oleada de dictaduras militares en América Latina, que tuvieron en el franquismo uno de sus principales referentes ideológicos.
Do pensamento à estratégia na metapolítica do radicalismo de direita
Authors: Silva Afonso
Published: May 2024

Este artigo procura contribuir para a compreensão do conceito de metapolítica e da sua prática no âmbito do radicalismo de direita, tendo em atenção a Nouvelle Droite e exemplos desta prática no caso português. Partindo do questionamento de Alain de Benoist acerca da relação entre a Nouvelle Droite e o pensamento do filósofo Peter Sloterdijk, afirma-se a utilidade do pensamento de Sloterdijk como ponto de partida para a compreensão da metapolítica e, consequentemente, da forma como a Nouvelle Droite a encara em torno da relação entre pensamento e estratégia. Atentando não só nessa conexão como também na ligação da discussão das ideias ao impacto político, realçam-se representações históricas transmitidas no caso português em articulação com a abordagem de mudança política caracterizada como metapolítica.

Authors: El-Abd Niamat M. , Hamouds Ragaa A. , Saddiq Amna A. , Al-Shaikh Turki M. , Khusaifan Tibra J. , Abou-El-Souod Ghada
Published: May 2024

Background and Aim: Natural antioxidants are crucial for preserving and enhancing the health, survival, reproduction, and reproductive function of poultry. Phycocyanin (PC) is a natural blue food colorant with various health benefits. The aim of this study was to extract Arthrospira platensis phycocyanin (ApPC) from A. platensis using simple and economical methods and investigate the impact of phytocyanin supplementation on the performance and fatty and amino acid profiles of broiler chicks.

Materials and Methods: PC was extracted from A. platensis by freezing and thawing, and optimization conditions such as pH and temperature were applied during storage periods. A total of 270 1-week-old Ross breed broiler chicks were randomly assigned to the following three treatment groups: basal diet supplemented with 0 mg of PC/kg diet (control), basal diet supplemented with 1 g PC/kg diet (T1), and basal diet supplemented with 2 g PC/kg (T2). In a completely randomized design, three cage replicates (30 birds each) were assigned to each of the three groups. The dietary effects of ApPC on growth performance (body weight gain [BWG], body weight [BW], feed intake, feed conversion ratio, serum constituents, and antioxidant indices) in broiler chickens, free amino acids, and fatty acids in muscles were evaluated.

Results: Total BWG and BW increased without a significant effect on the total feed consumption. Serum levels of total proteins and albumin increased with increasing ApPC supplementation. In addition, globulin levels significantly increased. There was a significant decrease in serum total cholesterol levels among the treatments. The activity of antioxidant enzymes (superoxide dismutase, catalase, glutathione, and total antioxidant capacity) is significantly increased. In contrast, an increase in ApPC caused a significant decrease in malondialdehyde. The content and quantity of fatty acids and amino acids in the meat of broiler chicks supplemented with PC varies.

Conclusion: The addition of PC to broiler chicken diets enhances antioxidant activities, BW, BWG, and meets quality requirements.

Published: May 2024

Background and Aim: The aim of any breeding process is to create a herd based on certain parameters that reflect an ideal animal vision. Targeted herding involves selecting the source of breeding material to be imported from another country. Therefore, there is a problem in selecting a breeding material importer to rapidly form a uterine canopy with the required properties. The purpose of this study was to evaluate a set of predictive milk productivity traits in Holstein cattle across countries.

Materials and Methods: This research was based on records of 819,358 recorded animals from 28 countries born after January 1, 2018, from open databases. We used the Euclidean metric to construct dendrograms characterizing the similarity of countries according to the complex milk productivity traits of the daughters of bulls. The Ward method was used to minimize intracluster variance when forming clusters and constructing the corresponding diagrams. Principal component analysis was used to reduce dimensionality and eliminate the effect of multicollinearity. The principal components were selected using the Kaiser–Harris criteria.

Results: A ranking of multidimensional complex milk productivity traits in different countries over the past 5 years was performed. A group of leading countries led by the USA was established according to the studied indicators, and the possible reasons for such a division into groups were described.

Conclusion: The pressure of purposeful artificial selection prevails in comparison with the pressure of natural selection concerning milk productivity traits in a certain group of countries, which allows specialists to choose suppliers when buying breeding animals and materials. The findings are based solely on data from recorded animals, which may not represent the entire breed population within each country, especially in regions where record-keeping may be inconsistent. It is expected that further studies will include regional data from large enterprises not part of Interbull, with mandatory verification and validation. An important element of such work is seen as the ability to compare the milk productivity of populations from different countries using a different scale, as well as studying the differentiation of countries by other selection traits of dairy.

Published: May 2024

Background and Aim: Low-level laser therapy (LLLT) has shown benefits as an alternative treatment of feline chronic gingivostomatitis by reducing pain and inflammation within the oral cavity. Extraoral application technique in cats provides more comfort compared to intraoral application. However, the efficacy of LLLT through buccal tissue is still controversial. This study aimed to investigate the penetration efficacy of LLLT using 830 nm continuous waves with various settings and different application techniques.

Materials and Methods: Twenty-four healthy cats were included in this study. The wavelength of LLLT was 830 nm with an output power of 200 mW through extraoral application, using fluences of 2 and 6 J/cm2 in continuous-wave mode. This study compared different distances (contact and non-contact) and three different transmission media (absent media, alcohol, and normal saline solution). Measurement of the laser power within the oral cavity is represented as the mean output power (MOP).

Results: Penetration efficacy was detectable for all fluences, distances, and transmission media, with an average buccal thickness of 2.68 mm. MOP did not differ between fluences of 2 and 6 J/cm2 (p = 0.19). In the absence of media, MOP was significantly higher compared with alcohol (p < 0.05) but was not significantly different from normal saline solution (p = 0.26).

Conclusion: Extraoral application of LLLT demonstrated penetration efficacy through the buccal tissue with both contact and non-contact skin (<10 mm). This is a potential alternative treatment for oral diseases in clinical practice. However, there is a need for further study on the efficacy of treatment in clinical practice.

Published: May 2024

Background and Aim: Biochemical blood testing is the main diagnostic indicator of the clinical condition of highly productive animals and a method of determining changes in metabolic disorders. This study focuses on metabolic changes (ketosis), which are of the utmost importance in the assessment of the health status of animals, as well as differences in intergroup characteristics. The main focus of this study is to demonstrate the influence of subclinical ketosis in highly productive cows on changes in biochemical blood parameters during different physiological periods to further prevent this disease, adjust feeding rations, and prevent premature culling of animals. This study aimed to evaluate and establish changes in the biochemical status dynamics of highly productive cows with metabolic disorders in an industrial livestock complex.

Materials and Methods: Blood samples were systematically collected from highly productive cows of the Simmental breed (n = 60) and served as the primary material for subsequent analyses. Each methodological step was designed to ensure evaluation of the metabolic changes associated with post-calving adjustments in highly productive dairy cows. This study employed a comprehensive approach integrating clinical assessments, laboratory analyses, biochemical evaluations, instrumental measurements, and statistical analyses.

Results: A biochemical blood test showed that the number of ketone bodies in the experimental group exceeded the norm, varied depending on the physiological state of the animals, and ranged from 0.89 to 1.45 mmol/L. At 10 days after calving, the highest indicator was 1.45 ± 0.05 mmol/L. This indicator was 1.05 mmol/L higher than that in the control group and exceeded the norm by 0.95.

Conclusion: Excess ketone bodies in the blood of animals led to accumulation in urine and milk, indicating a disturbance in metabolic processes in the body and a decrease in the quality of animal husbandry products. The sample size and the focus on a single breed from one geographical location may limit the generalizability of the findings. Further research should explore the mechanistic bases of ketosis development, potentially integrating genomic and proteomic approaches to understand the genetic predispositions and molecular pathways involved.

Keywords: biochemical composition of blood, ketone bodies, liver dystrophy, metabolism, phospholipids.

Published: May 2024

OBJECTIVES

Unplanned extubations (UEs) can be a frequent problem and are associated with adverse outcomes. This quality improvement initiative sought to reduce UEs from tube dislodgement in a level IV NICU utilizing methods applicable to other ICUs and performed with minimal monetary funds.

METHODS

From January 2019 to July 2023, an interdisciplinary quality improvement team used the Model for Improvement and performed sequential interventions to improve the outcome measure of UEs per 100 ventilator days. Process measures included adherence to a modified, site-specific UE care bundle derived from the Solutions for Patient Safety network, whereas the number of endotracheal tube-related pressure injuries was used as a balancing measure. Statistical process control charts and established rules for special cause variation were applied to analyze data.

RESULTS

Sequential interventions reduced the rate of UEs from a baseline of 2.3 to 0.6 UEs per 100 ventilator days. Greater than 90% adherence with the UE care bundle and apparent cause analysis form completion occurred since December 2020. There were no endotracheal tube-related pressure injuries.

CONCLUSIONS

A sustained reduction in UEs was demonstrated. Leveraging a multidisciplinary team allowed for continuous UE analysis, which promoted tailored consecutive interventions. UE care bundle audits and the creation of a postevent debrief guide, which helped providers share a common language, were the most impactful interventions. Next steps include disseminating these interventions to other ICUs across our hospital enterprise. These low-cost interventions can be scalable to other NICUs and PICUs.

Published: May 2024

Se analizó el ensamble de la comunidad de mamíferos terrestres no voladores del Refugio Nacional de Vida Silvestre Gandoca-Manzanillo, localidad de Gandoca, Costa Rica. Se emplearon trampas Sherman y Tomahawk, cámaras trampa, recorridos diurnos y nocturnos y se aplicaron encuestas a locales. Se obtuvo el registro de 22 especies, pertenecientes a seis órdenes; siendo Rodentia y Carnivora los más representativos, con ocho y seis especies respectivamente. De la riqueza total, 9,1 % se encuentra categorizada en el apéndice I; 4,5 % en el apéndice II y 27,3 en el apéndice III del CITES. De acuerdo con la UICN, Ateles geoffroyi se encuentra incluido en la categoría peligro de extinción, mientras que Alouatta palliata y Cebus imitator se encuentran en la categoría vulnerable. Se aplicó el índice Prioridades de Conservación, suma de índices (SUMIN) elaborado por Reca et al., (1994); encontrando que cuatro de las especies registradas correspondieron con la categoría máxima prioridad de conservación y ocho se ubican en atención especial. Mediante las encuestas se obtuvo información de 37 especies. Se destaca que el 90 % de los entrevistados conoce el papel ecológico que desempeñan los mamíferos y el 75 % señaló disminución en sus poblaciones causada por la cacería (58 %) y la deforestación (32 %). Se concluye que la localidad de Gandoca tiene una riqueza alta de mamíferos terrestres y su ensamblaje de especies posee características particulares, como la ausencia de grandes depredadores. Existen acciones antrópicas que están alterando la composición y abundancia de la mastofauna de la zona.

In Venezuela, Antillean manatees (Trichechus manatus manatus) have declined mainly due to habitat loss and degradation, but other threats to the species persist. The objective of this work was to investigate the manatee distribution and conservation issues in Maracaibo Lake, Venezuela. Aiming to collect evidence on manatee presence, we conducted 404.14 hours of boat-based surveys and observations from the shore during 2003, 2004, 2009, and 2010. Environmental parameters were collected in areas where manatees were observed including pH, temperature, dissolved oxygen, salinity, transparency, and depth. Also, we recorded plants or algae that could serve as potential food for manatees. We developed 96 informal and opportunistic talks with local fishermen, to gather information about manatee occurrence, boat traffic, and people’s perception of the species. Finally, we reviewed published and unpublished documents containing information on manatees in Maracaibo Lake. The resulting database contains information on 39 sightings and 13 reports of dead manatees. The known causes of death were poaching, vandalism, boat collision, and entanglement in fishing nets. The Maracaibo Lake offers many suitable habitats for manatees, but also faces a wide array of conservation problems that represent critical threats to this endangered subspecies. Long-term monitoring of this population and potential sources of mortality is highly needed.

The composition of fish assemblages in the Alvarado Lagoon System was updated with information collected between 1966 and 2008, divided into nine collection periods. A temporal analysis of the variation in species richness, species richness indices, rarity, and composition of ecological and trophic guilds was also carried out. A total of 113 species were recognized, 66 of which were present in most of the collection periods, forming a group with a constant presence in the lagoon system, in which marine and freshwater species predominated. This group showed the highest levels of similarity between collection periods; this was confirmed by the richness and rarity indices. Functionally, the composition of the ecological and trophic guilds did not show significant differences. The composition of the trophic guilds showed a prevalence of invertebrate consumers, macrocrustaceans, and small fish, supporting the fact that migratory marine species were the most numerous, with minor contributions from the other guilds. The contribution of marine or freshwater visitor species was not important in the characteristics of the assemblages. These results suggest that the environmental conditions of the Alvarado Lagoon System have remained without severe changes during the study period, thus allowing both the constancy of the fish community and that of the ecological and trophic guilds.

Authors: González-Espangler Liuba
Published: May 2024

La continuidad de la formación del especialista de Ortodoncia, en tiempos de pandemia por la COVID-19, constituye todo un reto para los docentes. Por ello, este ensayo reflexiona y presenta, tomando como referencia el primer año de la mencionada especialidad (debido a su complejidad), la experiencia con la virtualización de la formación posgraduada durante este periodo en Santiago de Cuba. Durante esta experiencia, las alternativas que se han propuesto incluyen a las diferentes habilidades a desarrollar según formas de organización de la enseñanza, las cuales abarcan desde actividades (base de datos, foro, tarea), recursos virtuales (archivo, carpeta o tarea) hasta tipos de evaluación. En todas estas clases, a excepción de la Educación en el Trabajo, se implementó la modalidad de clase invertida. Finalmente, se consideró que esta modalidad se configuró como una alternativa para darle continuidad al proceso de enseñanza aprendizaje y favorecer la adquisición de habilidades de manera independiente y creadora.

Objetivo: indagar por las ideas previas que presentan los estudiantes de Odontología, que se encuentran cursando entre V a X semestre, respecto al manejo ambulatorio de infecciones odontogénicas –IO- en niños. Métodos: se aplicó un estudio cualitativo-interpretativo con la participación de 60 estudiantes. Las respuestas dadas en una entrevista semiestructurada, la cual contó con ocho preguntas guía abiertas, fueron la unidad de análisis. El procedimiento tuvo cuatro fases. En la primera, preparatoria, se construyó el marco teórico-conceptual como base para interpretar lo manifestado por los estudiantes y se elaboraron las preguntas-guía; para la segunda fase, de recolección de información, se realizaron las entrevistas semiestructuradas presenciales, para ello, los participantes se citaron individualmente en la oficina de investigación. Durante la fase analítica se establecieron las categorías previas: concepto, etiología, evolución, manejo ambulatorio, vías de diseminación, tratamiento farmacológico. La información recabada se vació, depuró y codificó para hacer la exploración con técnica interpretativa y análisis de contenido. En la cuarta fase, de reporte, se presentó un informe con los resultados. Resultados: los estudiantes reconocen que esta enfermedad afecta a pacientes de cualquier edad, sexo y con condición sistemática comprometida. Conclusiones: se requiere una estrategia educativa que permita afianzar el manejo ambulatorio de las IO desde lo propuesto por la ciencia para lograr un aprendizaje significativo. Se requiere enfatizar en el manejo ambulatorio del paciente con infección odontogénica.
De la modernidad a la mierdandad
Authors: Dufour Dany-Robert
Published: May 2024

En este artículo parto de la reflexión sobre dos textos del filósofo y médico Bernard de Mandeville en los cuales estaría configurado lo que denomino el “software del capitalismo”, que, junto al diagnóstico realizado por Freud hace cien años del malestar de la cultura, permite comprender el riesgo que tiene la sociedad actual, posmoderna, de cambiar completamente lo que llamamos humano. La expansión de la pulsión de muerte y la caída de los regímenes alternativos al capitalismo, junto a una crítica de la división de saberes, que favorece la razón instrumental en detrimento de la razón sintética y crítica, me lleva a plantear que los pensadores en ciencias humanas y sociales estamos encerrados en nuestras disciplinas y no logramos comprender el posible final cercano de la aventura humana. El psicoanálisis debe interpretar su partitura en esta sinfonía de la última oportunidad, para evitar ser reemplazado por terapias comportamentales, mostrando que si bien hay una línea de bajo disarmónica que busca la muerte, hay otra, armónica, que busca la vida.
El síntoma a riesgo del trastorno
Authors: De Castro Korgi Sylvia
Published: May 2024

Con el fin de extraer conclusiones sobre el lugar del psicoanálisis en el mundo contemporáneo y, en particular, sobre lo que le demanda al psicoanálisis como teoría y como práctica, en el presente artículo vuelvo sobre algunas elaboraciones de Lacan respecto al síntoma como una suerte de actualización de la praxis psicoanalítica con respecto a la enseñanza de Freud. El horizonte en el que se inscribe mi reflexión es el de las distintas mutaciones que han tenido lugar en el mundo contemporáneo y sus efectos, asunto que podemos situar en los desarrollos que Lacan ofrece acerca del discurso capitalista. Mi interés es volver sobre algunos elementos en juego de lo que se ha llamado la “subjetividad de la época”, teniendo en cuenta el alcance que pueden tener algunos diagnósticos y su relación con lo que está en juego para los sujetos en la actualidad del discurso. De esto último, destaco al síntoma por su valor y función como aquello mismo que interroga los efectos de su desvalorización cuando queda reducido a simple trastorno.
¿Tabú sin tótem? Agujero en la pandemia
Authors: Figueroa Muñoz Mario Bernardo
Published: May 2024

Estas reflexiones, desde el punto de vista de un psicoanalista, no pretenden desconocer las múltiples diferencias de las cifras de contagios y de muertes ocurridas al comienzo de la pandemia, ni tampoco hacer un inventario de los muchos cambios que la crisis sanitaria introdujo en nuestras vidas con las variadas manifestaciones de malestar sufrido durante los primeros meses de confinamiento. Me detendré, más bien, en un hecho sencillo y muy extendido, que ha estado en el centro de la cotidianidad de nuestra vida en los meses posteriores, la falta. Tal vez por lo generalizado y porque sus razones parecen justificadas a la mayoría, pasa inadvertido; pero creo que si reparamos en el agujero y asumimos lo que implica, sin renegarlo o ignorarlo radicalmente como si nada hubiera pasado, podría tener importantes consecuencias.
Estudios de laboratorio para el control de Ceratitis capitata (Wiedmann)(Diptera: Tephritidae)(Mosca del Mediterráneo) con Beauveria bassiana
Authors: Porras Luis , Lecuona Roberto
Published: May 2024

Con el objetivo de seleccionar cepas promisorias de Beauveria bassiana para el control de Ceratitis capitata, se realizó, en condiciones de laboratorio, una serie de ensayos empleando la mosca adulta como estado vulnerable al parasitismo por el hongo entomopatógeno. Para la selección se utilizó una concentración de 5x109 CV.m-2 del hongo. Se determinó la CL90, la sobrevivencia media (SM), la compatibilidad con insecticidas, además de ensayos de producción con el hongo. Así como la compatibilidad de los insecticidas Mercaptotion 100% CE (Lupara) y Dimetoato 40% CE (Sistémico Icona) con las cepas seleccionadas. Se cuantificó la viabilidad de los conidios en platos de Petri pos-tratamiento, a 50%, 100% y 200% de la dosis comercial del insecticida. A partir de 7 cepas evaluadas (mortalidad 97%-14%) fueron seleccionadas la Bb 26, la Bb 259, la Bb 132, y la Bb 238. Los valores de CL90 estuvieron entre 1x109 y 3,8 x1011 CV.m-2 (Bb 238 y Bb 26, respectivamente). La SM de las cepas varió de 7-12 días (Bb 238 y Bb 26, respectivamente). La mayor producción fue de 7x109 UFC.mg-1 y 20,7 g.conidios.kg-1 de arroz (Bb 26). Todas las cepas fueron compatibles con Mercaptotion y la Bb 132 presentó la mayor compatibilidad con el Dimetoato. En conclusión, los ensayos en el laboratorio permitieron seleccionar cepas de B. bassiana con potencial para controlar C. capitata.
Susceptibilidad de los estadios L2 y L3 de Phyllophaga elenans a una cepa nativa de Heterorhabditis sp. en condiciones de invernadero

Se evaluó el efecto de 6 cepas nativas de nematodos entomopatógenos (NEP) sobre las larvas L2 de Phyllophaga elenans. La cepa que presentó los mejores resultados, Heterorhabditis sp. CIA-NE-07 fue evaluada a 125, 225, 375, 500 y 625 nematodos.larva-1 para determinar su patogenicidad sobre larvas L2 y L3 de P. elenans. En el estadio L2 se observó que a los 7 días, todas las concentraciones, con excepción de la dosis 125 nematodos.larva-1, causaron una mortalidad significativamente mayor que el testigo, en el cual no se presentaron muertes. A los días 14, 21 y 28 todos los tratamientos inoculados se diferenciaron significativamente del tratamiento control, observándose al día 30 una mortalidad del 68% con la dosis mayor utilizada. Se determinó que la dosis letal media correspondió a 475 nematodos. larva-1. El tiempo letal medio fue de 7,5, 8,5 y 17,5 días para las concentraciones de 625, 500 y 225 nematodos.larva-1, respectivamente. La inoculación con NEP no causó, en el estadio L3, diferencias significativas entre tratamientos al día 7, mientras que a los días 14, 21 y 28 las dosis de 500 y 625 nematodos.larva-1 presentaron una mortalidad significativamente mayor que el control. La mortalidad mayor (24%), se obtuvo al día 30 con la dosis de 625 nematodos.larva-1. La diferencia observada en los porcentajes de infección entre larvas L2 y L3 puede deberse a mecanismos de defensa o escape que podrían actuar en el estadio larval L3 de P. elenans.
