A putative calcium-ATPase of the secretory pathway family may regulate calcium/manganese levels in the Golgi apparatus of Entamoeba histolytica.

Calcium regulates many cellular processes in protozoa, including growth, differentiation, programmed cell death, exocytosis, endocytosis, phagocytosis, fusion of the endosomes of distinct stages with phagosomes, fusion of phagosomes with lysosomes, and recycling the membrane. In Entamoeba histolytica, the protozoa responsible for human amoebiasis, calcium ions are essential for signaling pathways that lead to growth and development. In addition, calcium is crucial in the modulation of gene expression in this microorganism. However, there is scant information about the proteins responsible for regulating calcium levels in this parasite. In this work, we characterized a protein of E. histolytica that shows a close phylogenetic relationship with Ca2+ pumps that belong to the family of secretory pathway calcium ATPases (SPCA), which for several organisms are located in the Golgi apparatus. The amoeba protein analyzed herein has several amino acid residues that are characteristic of SPCA members. By an immunofluorescent technique using specific antibodies and immunoelectron microscopy, the protein was detected on the membrane of some cytoplasmic vacuoles. Moreover, this putative calcium-ATPase was located in vacuoles stained with NBD C6-ceramide, a Golgi marker. Overall, the current findings support the hypothesis that the presently analyzed protein corresponds to the SPCA of E. histolytica.

Entamoeba invadens: Identification of a SERCA protein and effect of SERCA inhibitors on encystation.

Calcium has an important role on signaling of different cellular processes, including growth and differentiation. Signaling by calcium also has an essential function in pathogenesis and differentiation of the protozoan parasites Entamoeba histolytica and Entamoeba invadens. However, the proteins of these parasites that regulate the cytoplasmic concentration of this ion are poorly studied. In eukaryotic cells, the calcium-ATPase of the SERCA type plays an important role in calcium homeostasis by catalyzing the active efflux of calcium from cytoplasm to endoplasmic reticulum. Here, we reported the identification of SERCA of E. invadens (EiSERCA). This protein contains a putative sequence for endoplasmic reticulum retention and all domains involved in calcium transport identified in mammalian SERCA. By immunofluorescence assays, an antibody against SERCA of E. histolytica detected EiSERCA in a vesicular network in the cytoplasm of E. invadens trophozoites, co-localizing with calreticulin. Interestingly, EiSERCA was redistributed close to plasma membrane during encystation, suggesting that this pump could participate in regulate the calcium concentration during this process. In addition, thapsigargin and cyclopiazonic acid, both specific inhibitors of SERCA, affected the number and structure of cysts, supporting the hypothesis that calcium flux mediated by SERCA has an important role in the life cycle of Entamoeba.

High baseline expression of IL-6 and IL-10 decreased CCR7 B cells in individuals with previous SARS-CoV-2 infection during BNT162b2 vaccination.

The current pandemic generated by SARS-CoV-2 has led to mass vaccination with different biologics that have shown wide variations among human populations according to the origin and formulation of the vaccine. Studies evaluating the response in individuals with a natural infection before vaccination have been limited to antibody titer analysis and evaluating a few humoral and cellular response markers, showing a more rapid and intense humoral response than individuals without prior infection. However, the basis of these differences has not been explored in depth. In the present work, we analyzed a group of pro and anti-inflammatory cytokines, antibody titers, and cell populations in peripheral blood of individuals with previous SARS-CoV-2 infection using BNT162b2 biologic. Our results suggest that higher antibody concentration in individuals with an earlier disease could be generated by higher production of plasma cells to the detriment of the presence of memory B cells in the bloodstream, which could be related to the high baseline expression of cytokines (IL-6 and IL-10) before vaccination.

A Calcium/Cation Exchanger Participates in the Programmed Cell Death and in vitro Virulence of Entamoeba histolytica.

Entamoeba histolytica is the etiologic agent of human amoebiasis, disease that causes 40,000 to 100,000 deaths annually worldwide. The cytopathic activity as well as the growth and differentiation of this microorganism is dependent on both, extracellular and free cytoplasmic calcium. However, few is known about the proteins that regulate the calcium flux in this parasite. In many cells, the calcium extrusion from the cytosol is performed by plasma membrane Ca2+-ATPases and calcium/cation exchangers. The aim of this work was to identify a calcium/cation exchanger of E. histolytica and to analyze its possible role in some cellular processes triggered by calcium flux, such as the programmed cell death and in vitro virulence. By searching putative calcium/cation exchangers in the genome database of E. histolyica we identified a protein belonging to the CCX family (EhCCX). We generated a specific antibody against EhCCX, which showed that this protein was expressed in higher levels in E. histolytica than its orthologous in the non-pathogenic amoeba E. dispar. In addition, the expression of EhCCX was increased in trophozoites incubated with hydrogen peroxide. This E. histolytica exchanger was localized in the plasma membrane and in the membrane of some cytoplasmic vesicles. However, after 10 min of erythrophagocytosis, EhCCX was found predominantly in the plasma membrane of the trophozoites. On the other hand, the parasites that overexpress this exchanger contained higher cytosolic calcium levels than control, but the extrusion of calcium after the addition of hydrogen peroxide was more efficient in EhCCX-overexpressing trophozoites; consequently, the programmed cell death was retarded in these parasites. Interestingly, the overexpression of EhCCX increased the in vitro virulence of trophozoites. These results suggest that EhCCX plays important roles in the programmed cell death and in the in vitro virulence of E. histolytica.

El cuidado de sí mismo en enfermería. una visión con perspectiva de género / Autocuidado na enfermagem. uma visão com perspectiva do gênero / The care of the self as in nursing. a visión with a gender perspective

The emancipatory pattern has allowed the foundation and development of the nursing discipline,towards a way of thinking from critical theory. The purpose of the study is to reflect on the possibilitythat the nursing professional has to develop through the personal pattern a strategy for the emancipationof consciousness in heteronormative-patriarchal structures within the control state apparatuses (health institutions) where technification, medicalization and pathologization of life is above self-care and healthcare as a human experience. To address the issue, the analytical category of Gender was used in atransversal way, which allows to make visible the power relations that generate inequalities based onsexual difference. Then, it is understood that all things, people or professions perceived as feminine (as inthe case of the nursing profession) are subordinated and oppressed compared to those perceived asmasculine. Caring and knowledge patterns for self-care are proposed as resistance to inequalitiesgenerated by the integration of the biomedical-heteropatriarchal model in nursing thought and practice. (AU)

El patrón emancipatorio ha permitido sustentar y desarrollar la disciplina de enfermería hacia unmodo de pensar desde la teoría crítica. El propósito del estudio es reflexionar sobre la posibilidad queposee el profesional de la enfermería para desarrollar a través del patrón personal una estrategia para laemancipación de conciencia en estructuras heteronormativas-patriarcales dentro de los aparatos decontrol (instituciones de salud) donde la tecnificación, la medicalización y patologización de la vida estápor encima del cuidado de sí y del cuidado de la salud como experiencia humana. Para abordar el tema,se utilizó de manera transversal la categoría analítica de género que permite visibilizar las relaciones depoder generadoras de desigualdades a partir de la diferencia sexual. Entonces, se entiende que todoaquello cosas, personas o profesiones percibidas como femeninas (como en el caso de la profesión deenfermería) quedan subordinadas y oprimidas frente a las percibidas como masculinas. Se propone elCaring y los patrones de conocimiento para el cuidado de sí como resistencia a las desigualdades quegenera la integración del modelo biomédico-heteropatriarcal en el pensamiento y praxis enfermera. (AU)

O padrão emancipatório permitiu o sustento e desenvolvimento da disciplina da enfermagem,uma forma de pensar a partir da teoria crítica. O objetivo do estudo é a reflexão sobre a possibilidade doprofissional da enfermagem para desenvolver através do padrão pessoal uma estratégia para aemancipação da consciência nas estruturas heteronormatórias-patriarcais dentro dos dispositivos decontrole (instituições de saúde) onde a tecnicação, medicalização e patologização da vida estão acima doautocuidado e da atenção à saúde como experiência humana. Para abordar a questão, categoria analíticade gênero foi utilizada de forma transversal para possibilitar tornar visíveis as relações de poder quegeram desigualdades a partir da diferença sexual. Entende-se então que todas as coisas, pessoas ouprofissões percebidas como femininas (como no caso da profissão da enfermagem) são subordinadas eoprimidas contra aquelas percebidas como masculinas. Padrões de cuidado e autocuidado são propostoscomo resistência às desigualdades geradas pela integração do modelo biomédico-heteropatriarcal aopensamento e prática do enfermeiro. (AU)

Introducción. El sexting se define como el envío de contenido erótico o pornográfico a través de dispositivos digitales, comúnmente el móvil o smartphone, como una expresión de sexualidad cada vez más frecuente, y a pesar de que este fenómeno puede tener lugar con efectos positivos en quienes lo practican, existe muy poca evidencia relacionada con los mecanismos de participación, los motivos que conllevan, la percepción de las consecuencias, entre otros. Algunos autores lo han relacionado con factores como el consumo de sustancias, la promiscuidad y el nivel socioeconómico. Método. Estudio observacional, transversal y relacional, que incluyó a 300 estudiantes universitarios de enfermería, a través de un muestreo no probabilístico a conveniencia, en el que se aplicaron dos instrumentos, la escala de conductas sobre sexting y el instrumento de nivel socioeconómico familiar NSE AMAI. Resultados. El 64,7 % declara haber participado en prácticas de sexting, de los cuales el 26,2 % publicó una imagen suya a través de sus redes sociales, el 13,9 % declaró realizarlo cuando bebe alcohol y el 43,8 % reportó que es falso que el sexting los hace sentir inmorales. Se encontraron relaciones de prevalencia e intensidad del sexting con el nivel socioeconómico y la vida sexual activa. Conclusión. Al entender los distintos factores que predominan en esta práctica se pueden desarrollar diferentes intervenciones contextualizadas en los grupos poblacionales de riesgo, que sean accesibles por ambas partes, lo que permite una libre expresión de la sexualidad sin comprometer la seguridad de las personas.

Introduction: Sexting is defined as sending erotic or pornographic contents through digital devices, usually cell phone or smartphone, which is becoming an increasingly frequent sexual expression. In spite of the fact that it may occur with positive effects for those who do it, there is scarce evidence related to the participation mechanism, the reason driving them, the perception of consequences, among others. Some authors have related sexting to substances use, promiscuity and socioeconomic level. Methods: It is a relational, cross-sectional and observational study including 300 college students of nursing through a non probabilistic sampling using two instruments, the sexting behavioral scale and the family income-level instrument NSE AMAI. Results: Among the students, 64.7 % stated to have participated in sexting, 26.2% stated to have posted his/her picture in the social media, 13.9% stated to do sexting while been drunk and, 43,8% deemed as false that sexting would make them feel immoral. Prevalence and intensity relationship were found between sexting and income level and having an active sexual life. Conclusion: Understanding the different factors prevailing in the sexting allows developing different contextualized interventions in the risk populations groups that can be accessible to both ends. This would allow the free expression of one's sexuality without endangering the people's safety.

Edad, género y resiliencia en la conducta sexual de riesgo para ITS en adolescentes al Sur de México / Age, gender and resilience in sexual risk behavior of STI among adolescents in Southern Mexico

Objetivo: Comparar las conductas sexuales de riesgo en estudiantes de preparatoria y diferenciar por edad, género y nivel de resiliencia sexual. Material y métodos: Estudio descriptivo, transversal y explicativo. La población de interés estuvo conformada por 182 adolescentes de 15 y 16 años de dos instituciones educativas. La selección de la muestra fue mediante un muestreo aleatorio estratificado. Resultados: Los instrumentos de medición mostraron medidas de confiabilidad aceptables. El 69% de los adolescentes refirió contar con 16 años de edad, mientras que el 64% correspondió al género femenino. Los adolescentes de 16 años tuvieron promedios más altos en las conductas sexuales de riesgo (M = 12.1, DE = 23.3) que los adolescentes de 15 años (M = 4.76, DE=14.6, U=2,984.0, p=.038). En cuanto al género se presentaron diferencias significativas, las mujeres presentaron (M = 7.45, DE = 2.77) los hombres (M = 8.01, DE=2.03, U=3,714.0, p=.017). Mientras que el nivel de resiliencia sexual también fue diferente, los adolescentes de 15 años mostraron niveles de resiliencia más bajos (M=60.5, DE=13.6) que los adolescentes de 16 años (M=65.0, DE=17.3; U=2,809.0, p=.034). El Modelo de Regresión Lineal identificó que las variables que mayor contribución tuvieron fueron la edad, género y estado civil para la conducta sexual de riesgo (F=1.85, R2ajustada=.065, p=.052). En otro modelo la edad, genero y estado civil fueron significativas para el desarrollo de la resiliencia (F=5.4, R2ajustada=.07, p=.001). La investigación sobre la conducta sexual del adolescente y los factores que influyen en el comportamiento, es útil para comprender lo que motiva a los adolescentes en participar o evitar las conductas de riesgo sexual (AU)

Objective: To compare the sexual risk behavior in high school students and differentiate by age, gender and level of sexual resilience. Methods: Descriptive, transversal and explanatory study. The target population consisted of 182 adolescents aged 15 to 16 years of two educational institutions. The selection of the sample was using a stratified random sampling. Results: Measuring instruments showed acceptable reliability measures. 69% of adolescents reported having 16 years of age, while 64% were female. Teenagers of 16 years had higher averages in sexual risk behaviors (M = 12.1, SD = 23.3) than adolescents of 15 years (M = 4.76, SD = 14.6, U = 2984.0, p = .038). Regarding gender, significant differences were found, women had (M = 7.45, SD = 2.77) for men (M = 8.01, SD = 2.03, U = 3714.0, p = .017). While the level of sexual resilience was also different, teens 15 years showed lower levels of resilience (M = 60.5, SD = 13.6) than adolescents of 16 years (M = 65.0, SD = 17.3; U = 2809.0, p = .034). The Linear Regression Model identified that the greatest contribution were variables were age, gender and marital status to sexual risk behavior (F = 1.85, R2ajustada = .065, p = .052). In another model age, gender and marital status were significant for the development of resilience (F = 5.4, R2ajustada = .07, p = .001). Research on adolescent sexual behavior and the factors that influence behavior, it is useful to understand what motivates adolescents to participate or avoid sexual risk behaviors (AU)

Cuidado de enfermería transpersonal con base en la teoría del caring a una mujer con cáncer de mama / Transpersonal nursing care based on the caring theory for a woman with breast cancer

Resumen:

Introducción: el pensamiento de Jean Watson se basa en dos perspectivas: la filosofía de cuidados y la teoría de cuidados transpersonales. Watson basa su teoría en siete supuestos y 10 factores caritativos de cuidados, que después denomina proceso caritas de cuidados; en la práctica se incorpora el concepto de sufrimiento espiritual como parte del proceso y plan de cuidados de enfermería, con un enfoque primordial hacia la comprensión de la experiencia, el significado y el propósito de la vida. Objetivo: implementar un proceso de enfermería transpersonal con base en los 10 procesos de cuidado del caring a una mujer con cáncer de mama.

Metodología: para la valoración se utilizó un mapa de cuidados con base en el estudio fenomenología) de la persona; se determinaron siete diagnósticos con la taxonomía NANDA Internacional, Inc.; los planes de cuidado se formularon con las taxonomías NOC y NIC; la guía para la definición de intervenciones de enfermería estuvo constituida por los 10 procesos de cuidado y para describir la experiencia en la aplicación de esos 10 procesos del caring se utilizó la narrativa. Resultados: la empatía fue un valor que se puso en práctica para el cuidado de la mujer con cáncer de mama, lo que permitió valorar la dimensión espiritual de la persona y el reconocimiento de las fortalezas y debilidades para afrontar las situaciones que vivimos día a día.

Conclusiones: la incorporación de los 10 procesos de cuidado del caring en el plan de cuidado de enfermería transpersonal de la mujer con cáncer de mama implica que el profesional de enfermería desarrolle valores humanos esenciales y se reconozca como ser espiritual y de ayuda.

Abstract:

Introduction: Jean Watson's thought is based on two fundamental perspectives: philosophy of care and transpersonal care theory. She bases her theory in seven assumptions and 10 caritative care factors, named after Watson's Caritas Process (CP); in practice, the concept of spiritual suffering is incorporated as part of the process and nursing care plan, with primary focus on understanding the experience, the meaning and purpose of life.

Objective: To implement a transpersonal nursing process based on the 10 processes of the caring theory for a woman with breast cancer.

Methods: For the valuation, a care map was used based on the phenomenological study of the individual; seven diagnoses using NANDA International, Inc. taxonomy were determined; care plans were formulated with NIC and NOC taxonomies; the guidance for nursing interventions were the 10 care (carative) processes; and narrative was used to describe the experience of implementing those 10 processes.

Results: Empathy was a value implemented for women with breast cancer's care, allowing to assess the spiritual dimension of the person in its own unique personality and recognizing the strengths and weaknesses for dealing with situations that humans live everyday.

Conclusions: The addition of the 10 processes in Caring's care plan of transpersonal nursing care to women with breast cancer implies that the nurse develops essential human values and recognizes herself as a spiritual being of help.

Conducta sexual de riesgo para VIH/SIDA en jóvenes universitarios / Sexual risk behavior for HIV/AIDS in university students
