Published: January 2024

Background

Lymphaticovenous anastomosis (LVA) is a promising microsurgical treatment for lower extremity lymphedema (LEL). Lymphoscintigraphy effectively assesses lower limb lymphatic systems before LVA, but its role in predicting the therapeutic outcomes of LVA is indeterminate. In this study we investigate the efficacy of preoperative lymphoscintigraphy using clinical findings to predict outcomes in gynecological cancer-related LEL patients who underwent LVA.

Methods

A retrospective review was conducted on consecutive gynecological cancer patients with LEL who had undergone LVA between June 2018 and June 2021. The therapeutic efficacy was assessed by measuring the change rate of the lower extremity lymphedema index (LELi) six months after surgery. Clinical data and lymphoscintigraphic findings were analyzed to assess therapeutic efficacy of LVA.

Results

Out of the 60 evaluated legs, 83.3% of the legs showed improved results after LVA. Univariable linear regression analysis revealed that higher preoperative LELi, and ovarian cancer were associated with superior LELi change rate (LC rate). Absence of dermal backflow (DBF) on lymphoscintigraphy was associated with inferior LC rate. Multivariable linear regression analysis identified ovarian cancer and higher preoperative LELi were independently correlated with favorable outcomes, while the absence of DBF was independently correlated with inferior outcomes.

Conclusion

The results of this study emphasizes the effectiveness of preoperative lymphoscintigraphy, preoperative LELi, and primary malignancy as predictors of LVA outcomes in gynecological cancer-related LEL patients.
Dynamic asymmetric spillovers and connectedness between Chinese sectoral commodities and industry stock markets
Authors: Lou Yu , Xiao Chao , Lian Yi
Published: January 2024

This study investigates the dynamic and asymmetric propagation of return spillovers between sectoral commodities and industry stock markets in China. Using a daily dataset from February 2007 to July 2022, we employ a time-varying vector autoregressive (TVP-VAR) model to examine the asymmetric return spillovers and dynamic connectedness across sectors. The results reveal significant time-varying spillovers among these sectors, with the industry stocks acting as the primary transmitter of information to the commodity market. Materials, energy, and industrials stock sectors contribute significantly to these spillovers due to their close ties to commodity production and processing. The study also identifies significant asymmetric spillovers with bad returns dominating, influenced by major economic and political events such as the 2008 global financial crisis, the 2015 Chinese stock market crisis, the COVID-19 pandemic, and the Russia-Ukraine war. Furthermore, our study highlights the unique dynamics within the Chinese market, where net information spillovers from the stock market to commodities drive the financialization process, which differs from the bidirectional commodity financialization observed in other markets. Finally, portfolio analysis reveals that the minimum connectedness portfolio outperforms other approaches and effectively reflects asymmetries. Understanding these dynamics and sectoral heterogeneities has important implications for risk management, policy development, and trading practices.
Elimination of Chlamydia muridarum from the female reproductive tract is IL-12p40 dependent, but independent of Th1 and Th2 cells

Published: January 2024

Chlamydia vaccine approaches aspire to induce Th1 cells for optimal protection, despite the fact that there is no direct evidence demonstrating Th1-mediated Chlamydia clearance from the female reproductive tract (FRT). We recently reported that T-bet-deficient mice can resolve primary Chlamydia infection normally, undermining the potentially protective role of Th1 cells in Chlamydia immunity. Here, we show that T-bet-deficient mice develop robust Th17 responses and that mice deficient in Th17 cells exhibit delayed bacterial clearance, demonstrating that Chlamydia-specific Th17 cells represent an underappreciated protective population. Additionally, Th2-deficient mice competently clear cervicovaginal infection. Furthermore, we show that sensing of IFN-γ by non-hematopoietic cells is essential for Chlamydia immunity, yet bacterial clearance in the FRT does not require IFN-γ secretion by CD4 T cells. Despite the fact that Th1 cells are not necessary for Chlamydia clearance, protective immunity to Chlamydia is still dependent on MHC class-II-restricted CD4 T cells and IL-12p40. Together, these data point to IL-12p40-dependent CD4 effector maturation as essential for Chlamydia immunity, and Th17 cells to a lesser extent, yet neither Th1 nor Th2 cell development is critical. Future Chlamydia vaccination efforts will be more effective if they focus on induction of this protective CD4 T cell population.

Authors: Yunarto Yuliana , Ratih Dewi , Wistiani Wistiani
Published: January 2024

Background  Imbalance of oxidants and antioxidants contributes to the sepsis process. Nitric oxide (NO) is an oxidant produced abundantly during sepsis and plays key role in the pathogenesis of hypotension in septic shock. Vitamin C functions as a potent antioxidant to scavenge free radicals, reduce endothelial permeability, cellular apoptosis, and endogenous vasopressor synthesis cofactor. Vitamin C prevents excessive production of NO by suppressing inducible nitric oxide synthase (iNOS) expression.

Objective To analyze for a possible correlation between serum vitamin C and NO levels in children with septic shock.

Methods This cross-sectional study was conducted in Dr. Kariadi Hospital, Semarang, Central Java, Indonesia. A total of 40 children with septic shock aged 1 month - 18 years were consecutively recruited. Serum vitamin C and serum NO levels were measured using colorimetric assay kits.

Results Of 40 children with septic shock, 21 (52.5%) were male, 21 (52.5%) were undernourished, 25 (62.5%) were on mechanical ventilators, and 10 (25%) required more than one vasoactive agent. Blood gas analysis revealed acidosis in 31 (77.5%) children. Subjects’ median age was 20 months (2-214 months). Mean serum vitamin C level was 7.35 (SD 2.723) µg/mL and mean serum NO was 47.25 (SD 19.278) µmol/L. There was no significant correlation between serum vitamin C levels and serum NO in children with septic shock (r=0.056; P=0.732).

Conclusion Serum vitamin C levels and serum NO has no correlation in children with septic shock.

Published: January 2024

Background  Zinc is one of the micronutrients that is found deficient in preterm infants. To date, no parenteral zinc supplements are available in Indonesia and there is no recommendation established for routine zinc supplementation in preterm infants.

Objective To evaluate the impact of zinc supplementation on growth indicators and morbidity in preterm infants.

Methods This double-blind, randomized controlled trial included preterm infants aged 28-32 weeks who were assigned to one of two groups: the first group received a 10 mg zinc supplementation, while the second (control) group received a placebo. At discharge or at a maximum of 40 weeks post-menstrual age (PMA, calculated from the first day of the mother's last menstrual period), the following were evaluated : growth indicators (weight, length, and head circumference), serum zinc level, zinc supplementation side effects, and morbidity rate (intraventricular hemorrhage/IVH, necrotizing enterocolitis/NEC, btonchopulmonary dysplasia/BPD). Data were analyzed with independent T-test using SPSS version 22 software.

Results Seventy-eight subjects were assigned to the zinc supplementation group and 76 subjects were assigned to the placebo group. Serum zinc level and mean body weight increment were significantly higher in the zinc group compared to the placebo group (P=0.00 and P=0.02, respectively). There were no significant differences between groups in mean body length or head circumference increment, nor in morbidity rate.

Conclusion  Preterm infants who received zinc supplementation have higher serum zinc level and mean body weight increment compared to the placebo group. No side effects are observed to have been caused by zinc supplementation.

Published: January 2024

Background Acute kidney injury (AKI) in sepsis is associated with an inflammatory process in kidney microcirculation and may increase morbidity and mortality in children. The neutrophil lymphocyte ratio (NLR) is an inflammatory biomarker of the inflammatory process in sepsis.

Objective To determine the role of NLR in predicting the severity of AKI and to describe the demographic and laboratory characteristics, as they relate to outcomes of pediatric patients with AKI and sepsis.

Methods This cross-sectional study was conducted in the PICU at Dr. Zainoel Abidin General Hospital (RSUDZA), Banda Aceh, Aceh. Medical record data were obtained from critically ill children with sepsis and AKI. Chi-square test was used to compare the proportions of each variable. We also calculated odds ratios to evaluate the AKI severity, PELOD-2 score, and patient outcomes. Spearman's analysis was used to look for a possible correlation between NLR and AKI severity in septic children.

Results Seventy-one subjects with sepsis and AKI were included. Subject characteristics were as follows: 63.4% males, 63.4% < 1 year of age, 56.3% with respiratory problems as a primary disease, 38% with AKI injury stage, and 54.9% subjects with PELOD-2 score ?10. There was no significant correlation between AKI severity and mortality (OR 3.04; 95%CI 0.990 to 9.378; P=0.052). Subjects with a PELOD-2 score ?10 had a 47.6 times higher chance of mortality in septic children with AKI compared to those with PELOD-2 scores <10. There was no correlation between NLR and AKI severity (r=0.019; P=0.878).

Conclusion There is no correlation between NLR and AKI severity. Sepsis accompanied by AKI may increase the risk of mortality in children. Septic children with more severe AKI tends to be less survive.

Published: January 2024

Addiction is a global social issue that poses significant crisis to individuals and their families’health and social aspects. The characteristics of addiction can vary depending on the region, culture, and context. Addictive behaviors such as drinking and gambling are associated with various psychosocial factors. We examined whether and how psychosocial factors (i.e., ego-resiliency, family cohesion, and social support) affect addictive behaviors, specifically drinking and gambling problems, by comparing the occurrences of both problems and related factors between college students in South Korea and Hawai‘i. We collected data from college students in South Korea (n= 503) and Hawai‘i (n= 217). Our findings showed that respondents from the Korean sample were more involved in drinking and gambling problems. In addition, we found that region was a factor associated with problem drinking and that there was a significant effect of social support on problem gambling. In conclusion, we discussed our key findings in-depth and suggested strategies to prevent and intervene early in addictive behaviors among college students.

The mass-charge binding energy as an explanation for the superfine adjustment of the hadron and baryon masses
Authors: Arneth Borros
Published: January 2024

Quantum chromodynamics (QCD) describes how mass is created at the quark level. This mechanism is special because the binding of quarks does not result in a mass loss or a release of energy, as in the case of the nuclear mass defect. Rather, mass is created by the binding of quarks. To achieve this binding, energy must be expended. At the same time, however, quarks are firmly bound to each other. Several authors have shown that the masses of the elementary particles as determined by means of QCD agree quite well with the experimentally determined values. In the following, superfine adjustment of the masses of the charged elementary particles is shown to be possible by considering the mass defect in terms of the mass-charge binding energy.
educación secundaria ante la emergencia climática
Authors: García-Vinuesa Antonio
Published: January 2024

La crisis climática plantea el mayor reto del siglo XXI para las sociedades humanas y para la vida en el planeta. Los posicionamientos de las comunidades científicas son concluyentes, el cambio climático está causado por las actividades humanas, y no parece que las diferentes naciones del mundo estén comprometidas a emprender y acelerar las acciones necesarias para mitigarlo y evitar el sufrimiento de los colectivos más vulnerables y vulnerados. Las posibles líneas de acción para transitar hacia sociedades descarbonizadas y sostenibles son diversas y complejas, y la educación debe ser un pilar fundamental para emprender transiciones ecosociales equitativas y justas desde el espacio local al global y desde el triple punto de vista social, ambiental y económico. Sin embargo, parece ser que la respuesta educativa a la crisis climática también está siendo precaria. En ella se tiende a obviar las dimensiones sociales y éticas del problema para centrar la mayor parte de los esfuerzos en transponer el conocimiento científico desde enfoques positivistas. Enfoques que inhiben o limitan las oportunidades de acción requeridas dado que eluden los dilemas éticos, sociales y políticos que es necesario plantear para impulsar acciones sociales realmente transformadoras.

FL learners in late adulthood: A report of seniors’ willingness to communicate in English in the classroom context
Authors: Borkowska Anna
Published: January 2024

The article aims to examine older learners’ points of view concerning their in-class will- ingness to communicate (WTC) in English and to identify their expectations regarding an English teacher. The instrument was a questionnaire that comprised – among others – of questions referring to variables that could exert an impact on third-agers’ WTC in English in class. The factors which were used as options in the closed and open-ended questions in the study had been identified by the third agers as the ones that positively or negatively shaped their in-class WTC in an earlier piece of qualitative research (Borkowska 2021a). The data analysis revealed that the informants (63 older participants) reported an eagerness to communicate in English, and they perceived speaking with the teacher as the most motivating type of interaction. The most crucial components of language instruction that boosted older adults’ WTC was gentle error correction, a friendly atmosphere, and teacher support that seemed to have a positive effect on their lower self-esteem. Similarly, an empathetic and patient instructor could be of great help in diminishing seniors’ self-depreciating views. In contrast, negative teacher attributes (e.g., anxiety, criticism) could lead to inhibiting the older participants’ WTC and active involvement during English classes.
Studying at higher education institutions in Poland as seen by students with disabilities in the context of the geographical model of disability
Authors: Zajadacz Alina , Kołodziejczak Anna
Published: January 2024

The subject addressed in the present paper is important for the current social and educational policy regarding persons with disabilities. The development of the accessible education concept should be based on the geographical model of disability, whose main principle is to focus on the varied social needs and adjust the conditions of the geographical environment accordingly rather than to concentrate on the disability itself. The main aim of the study was to recognise the opinions of students with disabilities about studying at Polish higher education institutions (HEI). The study was based on the results of online interviews including standardised questions (open- and close-ended). The time scope of the study covers the years 2019 and 2021. The research has shown that some students hide their disability until it is visible. As a result, they do not receive adequate support and limit the achievement of goals that were the main motivation for studying. Measures taken to support students with different needs at HEIs must have a systemic nature and be addressed to the entire academic community, as well as to the society.
Critical theory of the energy transformation: Sociology’s approach
Authors: Baranowski Mariusz
Published: January 2024

This article explores the critical theory of energy transformation within sociology, aiming to understand and enhance societal change. It investigates the shift from fossil fuels to renewable energy sources, analysing the socio-economic and geopolitical implications. Using empirical data, it reveals disparities between public discourse and actual emissions, unmasking power asymmetries and ‘green colonialism’ perpetuated by dominant nations and corporations. The study underscores the need for profound societal transformation rather than superficial energy shifts, advocating for the fusion of critical theory and capitalist critiques. It emphasises the importance of dismantling hegemonic control and fostering equitable energy transformation, calling for civic courage to challenge existing power structures. This work’s originality lies in integrating critical theory within sociology, offering insights into the socio-political dynamics influencing global decarbonisation efforts. Its value resides in a comprehensive analysis, unveiling interconnections between power, economics, and the environment in the context of energy transformation.

Finally, to show the accuracy and the validity of the proposed technique, we provide some numerical examples.
Lockerungen im österreichischen Maßnahmenvollzug –
Authors: Stempkowski Monika
Published: January 2024

Lockerungsmaßnahmen in Form von begleiteten und unbegleiteten Ausgängen sowie Phasen des Probewohnens ermöglichen während der Haft einen Kontakt zur Außenwelt und eine Vorbereitung des sozialen Empfangsraums für die Zeit nach der Entlassung aus dem Vollzug. Im Maßnahmenvollzug (dem österreichischen Pendant zum deutschen Maßregelvollzug) dienen sie darüber hinaus als wesentliche Informationsquelle, ob eine untergebrachte Person ausreichend für ein Leben in Freiheit vorbereitet ist und daher eine bedingte Entlassung erfolgen kann. In der vorliegenden Untersuchung wird die Praxis der Durchführung von Lockerungsmaßnahmen im Maßnahmenvollzug für psychisch kranke Personen beleuchtet. Die Ergebnisse zeigen auf, dass zwar die meisten Personen Lockerungen durchlaufen, aber individualisiert entschieden wird, welche und wie viele Formen von Lockerungen zu Einsatz kommen. Betrachtet man gleichzeitig die Behandlungen im Vollzug (bspw. durch den psychiatrischen oder den sozialen Dienst), Maßnahmen des Entlassungsmanagements, gerichtlich angeordnete Weisungen und die Häufigkeit einer Entlassung in eine betreute Nachsorgeeinrichtung, zeigt sich, dass sich Lockerungen in die jeweilige Behandlungsstrategie dahingehend eingliedern, dass jene Personen, die mehr Behandlung, mehr Nachbetreuung und mehr Kontrolle erfahren, auch häufiger Lockerungen durchlaufen. Bezogen auf die Wiederkehrerrate nach der bedingten Entlassung zeigen sich hingegen keine Unterschiede zwischen Personen mit mehr bzw. weniger Lockerungen. Im Sinne des Risk-Need-Responsivity-Modells kann vermutet werden, dass die Selektion für diese unterschiedlichen Behandlungsintensitäten in dem jeweiligen Rückfallrisiko der Personen begründet liegt. Ist dies der Fall, deuten die Ergebnisse darauf hin, dass die Differenzierung zwischen Personen mit hohen und niedrigem Risiko gelingen dürfte. Mögliche Hintergründe dieser Auswahl und sich daraus ergebende Forschungsfragen werden diskutiert.

All-dielectric tunable zero-refractive index metamaterials based on phase change materials
Authors: Yang Zhexi , Zhao Tianqi , Zhang Peng , Li Chenxia , Fang Bo , Hong Zhi , Yu Mingzhou , Jing Xufeng
Published: January 2024

We propose a tunable all-dielectric zero-index metamaterial based on phase change material. By constructing the alternating rod structure with phase change material and silica material, the zero-refractive index characteristic is realized. In order to verify the equivalent zero-index characteristic, we calculated the electromagnetic field distribution at center frequency. Based on phase invariance, it was found that this kind of metamaterial can achieve equivalent zero refractive index characteristics. To further achieve the polarization-insensitive zero refractive index, we propose a metamaterial structure based on the fishing nets structure. Based on the S-parameter inversion algorithm, the equivalent dielectric constant, equivalent permeability, equivalent impedance, and equivalent refractive index of the metamaterial were extracted. Based on the extracted equivalent parameters and the corresponding electromagnetic field distribution, the designed all-dielectric metamaterial has the tunable equivalent zero refractive index characteristic.

Published: January 2024

Die stetig voranschreitende Entwicklung im Bereich der Fertigung optischer und elektronischer Elemente auf Basis von Nanotechnologien führt seit Jahren zu einer steigenden Nachfrage nach hochpräzisen Nanomess- und Nanofabrikationsmaschinen (The International Roadmap For Devices And Systems, IEEE, 2020; C. Grant Willson and B. J. Roman, “The future of lithography: SEMATECH litho forum 2008,” ASC Nano, vol. 2, no. 7, pp. 1323–1328, 2008). Als technologisch besonders anspruchsvoll hat sich dabei die Fabrikation auf stark geneigten, gekrümmten, asphärischen und freigeformten Oberflächen herausgestellt (R. Schachtschneider, et al., “Interlaboratory comparison measurements of aspheres,” Meas. Sci. Technol., vol. 29, no. 13pp, p. 055010, 2018).

Published: January 2024

Ortega y Gasset afirmó “[...] la fenomenología no fue una filosofía para nosotros: fue... una buena suerte”. Esto se debió a que, a través de ella, pudo encontrar una salida del neokantismo. En consecuencia, Ortega entenderá que la fenomenología busca salvar la racionalidad sin ignorar la experiencia, es decir, sin olvidar, que todo sucede en la vida de cada individuo. Sin embargo, desde el principio se da cuenta de que este individuo no es algo aislado, sino que se forma en relación con el mundo, la circunstancia (“Yo soy yo y mi circunstancia y si no la salvo a ella, no me salvo yo”, dirá hacia 1914) y que la fenomenología debe recuperar el carácter ejecutivo de la vida. El presente ensayo recorrerá desde el encuentro de Ortega con la fenomenología hasta sus intuiciones acerca de la vida como realidad radical.

deshumanización como estrategia contra-económica en Pelea de gallos, de María Fernanda Ampuero
Authors: Rodal Linares Selma
Published: January 2024

En este artículo propongo que Pelea de gallos de Ampuero exhibe la naturalización de lo inhumano del capitalismo gore en las relaciones socioafectivas de la vida íntima. A partir de Sayak Valencia, explico cómo los cuentos muestran una economía simbólica que mercantiliza a los cuerpos femeninos y animales y convierte la violencia en contra de estos en productos de consumo. Luego, analizo los cuentos “Crías” y “Subasta”, para mostrar que los personajes femeninos devienen-animal-deshecho como estrategia para escapar de esta codificación. Considero que estos devenires redistribuyen la propiedad del saber de los humanos a los animales y a la naturaleza y subvierten la economía semántica y afectiva del consumismo como horizonte común. Estas formas de deshumanización le permiten a los cuerpos femeninos una reapropiación parcial y efímera del cuerpo que les ha sido robado.
Ariadnas: las Metamorfosis, de Rosi Braidotti, como clave del devenir animal e inmanencia radical en el arte feminista
Authors: Mercado Salas Raquel
Published: January 2024

Para ofrecer una ruta de lectura del pensamiento feminista-deleuziano, se pone a discusión el concepto cartografía propuesto por Braidotti, respecto a la recepción y reelaboración de la inmanencia radical, y la diferencia sexual en la filosofía actual. Se propone un símil de dicha recepción en la teoría y estudios del arte, particularmente en México. A través de Metamorfosis. Hacia una teoría materialista del devenir y los conceptos clave como devenir-mujer y devenir-insecto, se entabla una relación con los feminismos visuales situados en el sur global. El diálogo entre ambas recepciones, la filosófica y la artística, implica un acercamiento a la problematización y comprensión del conflicto capital-vida, además de las aportaciones posibles de la producción feminista, hace patente cómo se continúa en la teoría feminista actual una línea materialista, con profundas raíces clásicas, de una ontología del cuerpo.

Devenir otras. Alternativas sensibles contra la violencia en la literatura escrita por mujeres en México
Authors: Cabrera Manuel María Isabel
Published: January 2024

Ante los hechos violentos que la población y en particular las mujeres padecen como grupo en México, este trabajo busca sumar al ejercicio crítico de pensar las violencias simbólicas y fácticas, mostrar sus formas de reconocimiento y el trabajo discursivo que apuesta por la vida de las mujeres y la población vulnerable no sólo desde el dolor y la rabia, sino también  desde la apuesta por la supervivencia, por las estrategias que permitirían sustraerse al peso avasallador de sus formas, para devenir otras. Este trabajo analiza el trabajo de escritoras que invitan a encontrar en sus reflexiones, historias, relatos y personajes femeninos no sólo a víctimas, sino a subjetividades que evitan por diferentes medios a quedar aprisionadas por conceptos que sólo reiteran la violencia en sus cuerpos y en sus vidas.

El arte, constructor de esencialismo: mujer andaluza y sociedad, mito y arquetipo
Authors: Castillero Quesada Soledad
Published: January 2024

Al oír el término “mujer andaluza”, automáticamente vamos a visualizar una serie de características (y no otras) que van a corresponder con un modelo de patrón ideal visual. En esta conformación, el arte tiene es un pilar fundamental. Desde distintas corrientes y esferas tales como la pintura, el cine, la música o la literatura, atendemos a la construcción de un personaje donde la esencia se reduce a un plano mítico, desechando la propia identidad de las mujeresrepresentadas. En el siguiente artículo vamos a desgranar cómo la construcción de este ideal de mujer andaluza es esencialista, a partir del análisis de cuatro obras. Esto nos ayudará a entender cómo el impacto de esta mitificación no solo reside en la concepción estética,sino en la concepción cultural y por tanto su aceptación o rechazo en los diferentes planos de la vida socio política de las mujeres.
