ABSTRACT

Las técnicas de doble tinción y transparentación se han usado desde 1897, pero su utilidad ha sido poco explorada en los estudios anatómicos de micromamíferos adultos. No obstante, la combinación de estas técnicas con el análisis alométrico mutivariado posibilita el estudio de esqueletos poscraneales articulados de tales grupos de micromamíferos como los roedores, los cuales son muy limitados ya que casi siempre se enfocan en los cráneos. En este estudio, analizamos y comparamos la morfometría del esqueleto de Neotomodon alstoni con la de Meriones unguiculatus, Phodopus campbelli y Rattus norvegicus. Usamos la técnica de doble tinción y transparentación para analizar las relaciones morfométricas entre estos roedores utilizando sesenta caracteres esqueléticos. Se encontró que tres especies comparten dos correlaciones comunes y compartieron el mismo tipo de crecimiento isométrico en una de ellas; además se encontraron similitudes aparentes entre los patrones de la morfometría de P campbelli con el patrón de osificación descrito para la especie relacionada Mesocricetus auratus. Las diferencias en el crecimiento alométrico pueden representar también diferencias en el ritmo de desarrollo de acuerdo con el tipo de historia de vida de cada especie. Aquí demostramos que tanto la técnica de preparación como el método de análisis morfométricos son herramientas poderosas pero simples, para realizar estudios anatómicos y morfológicos en el laboratorio. Nuestros resultados reflejan las condiciones del desarrollo ontogenético derivados delpropio patrón de heterocronía para cada especie, y además representan la historia evolutiva de este grupo analizado. Sin embargo, consideramos que es deseable más investigación.


SUMMARY: Clearing and staining techniques have been present since 1897, However, their use in anatomical studies of adult micromammals has been limited. When using such techniques in combination with allometric method, it is possible to study articulated skeletons of micromammals, instead of relying only on the skulls, which is important in morphologically complicated groups as the rodents. Research involving multivariate allometric analysis of postcranial skeleton of rodents has been limited and confined to specific items. In this study, we analyzed and compared the morphometry of the skeleton of Neotomodon alstoni with that of Meriones unguiculatus, Phodopus campbelli and Rattus norvegicus. We applied the double staining and clearing technique in order to determine the morphometric relation between these rodents using sixty skeletal characters. We found that three species share two common correlations and one isometric, with apparent similarities between the morphometry patterns of P campbelli with the ossification pattern described for the related species Mesocricetus auratus. The differences in allometric growth could represent differences in the development stages according to the type of life history for each species. In this analysis we confirmed that both the preparation technique and morphometric analysis method, are simple yet verifiable tools for anatomical and morphological studies. Our results reflect the conditions of ontogenetic development derived from the heterochrony pattern for each species, representing the evolutionary history for this group. Therefore, as this approach continues to be discussed, ongoing research is warranted.

ABSTRACT

Introduction: perinatal mortality is characterized by fetal deaths that occur after the 22nd week of management and neonatal deaths that precede six full days of life. This indicator has been a matter of concern and discussion on the part of entities and organizations involved in comprehensive health care for women and children.Objective: to characterize perinatal deaths in the Metropolitan Region of Greater Vitória (RMGV) in Espírito Santo and identify associated maternal factors in the period between 2008 and 2017.Methods: ecological and descriptive study with a quantitative approach, carried out in 2019 on perinatal mortality from 2008 to 2017 at RMGV. Data collection was performed by extracting data from the SIM, SINASC, IBGE databases of the Espírito Santo State Health Department, about perinatal deaths and associated maternal factors. The research respects the ethical precepts of resolution 466/12 of the National Health Council.Results: the distribution of deaths did not occur homogeneously in the municipalities in the RMGV. The municipality of Vitória had the lowest perinatal mortality rates during the study period, on the other hand, in the comparative analysis between the different municipalities that make up the RMGV, the municipality of Fundão presents the worst scenario regarding perinatal mortality over the years. Regarding the underlying causes of death, it is noted that in this study, the three causes with the highest number of occurrences are complications of the placenta, umbilical cord and maternal affections, not necessarily related to the current pregnancy and intrauterine hypoxia.Conclusion: there were no significant changes in mortality rates in the Metropolitan Region of Greater Vitória. However, the main deaths occurred in neighborhoods with greater socioeconomic inequalities. Maternal causes were highly representative of deaths, raising issues associated with the improvement of public health policies.


Introdução: a mortalidade perinatal caracteriza-se pelos óbitos fetais que ocorrem a partir da 22ª semana de gestão e os óbitos neonatais que antecedem seis dias completos de vida. Este indicador tem sido motivo de preocupação e discussão por parte de entidades e organizações envolvidas na atenção à saúde integral da mulher e da criança. Objetivo: caracterizar os óbitos perinatais da Região Metropolitana da Grande Vitória (RMGV) no Espírito Santo e identificar fatores maternos associados, no período entre 2008 e 2017. Método: estudo ecológico e descritivo de abordagem quantitativa, realizado no ano de 2019 acerca da mortalidade perinatal entre os anos de 2008 a 2017 na RMGV. A coleta de dados foi realizada através extração dos dados das bases SIM, SINASC, IBGE da Secretaria de Saúde do Estado do Espírito Santo, acerca dos óbitos perinatais e fatores maternos associados. A pesquisa respeita os preceitos éticos da resolução 466/12 do Conselho Nacional de Saúde. Resultados: a distribuição dos óbitos não ocorreu de forma homogênea nos municípios na RMGV. O município de Vitória apresentou os menores índices de mortalidade perinatal durante o período estudado, em contrapartida, na análise comparativa entre os diferentes municípios que compõe a RMGV, o município de Fundão apresenta o pior cenário relativo à mortalidade perinatal ao longo dos anos. Acerca das causas bases de óbitos, nota-se que neste estudo, as três causas com maior número de ocorrência são complicações da placenta, do cordão umbilical e afecções maternas, não obrigatoriamente relacionadas com a gravidez atual e hipóxia intrauterina. Conclusão: não houve mudanças significativas nas taxas de mortalidade na Região Metropolitana da Grande Vitória. Contudo, os principais óbitos ocorreram em bairros com maiores desigualdades socieconomicas. As causas maternas representaram uma grande representatividade frente aos óbitos, levantando questões associadas a melhora de políticas públicas de saúde.

ABSTRACT

Introduction: the Systematization of Nursing Care is one of the main tools for the development and organization of services for nursing professionals, its application guides the planning of individualized care and focuses on the specific needs of each individual. Objective: the study's general purpose is to analyze primary health nursing care in light of the basic human needs theory. Methods: this is a descriptive study with a qualitative approach, developed in the city of Rio Branco, Acre, Brazil, with nurses from the Basic Family Health Units. As a method for organization and interpretation, we opted for the content analysis proposed by Bardin. Results: the Systematization of Nursing Care is perceived by nurses as an instrument for organizing care, but in practice, they think it is focused on assistance directed to the use of ministerial protocols. In this context, it was also evidenced that they focus on aid for health problems and complaints, indicating the anamnesis as a phase of the implemented nursing process with the other stages focused on the diagnosis of the disease and specific interventions. Conclusion: our findings showed that professionals in primary health care end up directing their care only to momentary complaints, failing to broaden their look as a whole. In this way, assistance occurs in a fragmented way, failing to meet the real needs of the population.


Introdução: a Sistematização da Assistência de Enfermagem é uma das principais ferramentas para o desenvolvimento e organização dos serviços dos profissionais da enfermagem, a aplicação da mesma orienta quanto ao planejamento de uma assistência individualizada e com foco nas necessidades específicas de cada indivíduo. Objetivo: analisar a assistência de enfermagem na atenção primaria à saúde à luz da teoria das necessidades humanas básicas. Método: trata-se de um estudo descritivo de abordagem qualitativa. A pesquisa foi desenvolvida no município de Rio Branco, com profissionais enfermeiros das Unidades Básicas de Saúde da Família. Como método para a organização e interpretação optou-se pela análise de conteúdo proposta por Bardin. Resultados: a Sistematização da Assistência de Enfermagem (SAE) é percebida pelos profissionais enfermeiros como um instrumento de organização do cuidado, porém estes na prática acabam achando que a SAE está voltada para a assistência direcionada ao uso de protocolos ministeriais. Nesse contexto, evidenciou-se ainda que estes focam a assistência em problemas de saúde e as queixas, indicando a anamnese como fase do processo de enfermagem implementado, sendo as demais etapas voltadas para diagnóstico da doença e intervenções pontuais. Conclusão: evidenciou que os profissionais na atenção primária à saúde acabam direcionando seus cuidados apenas para as queixas momentâneas, deixando de ampliar o olhar para o mesmo como um todo. Desse modo, a assistência ocorre de modo fragmentado, deixando de atender as necessidades reais da população

ABSTRACT

La mastocitosis cutánea crónica es una genodermatosis de etiología desconocida y que se encuentra dentro del grupo de enfermedades raras o poco frecuentes. Se caracterizan por el crecimiento y acumulación de causa desconocida de mastocitos en piel y otros órganos y se manifiesta como una urticaria pigmentosa. Se presenta el caso de un paciente de sexo masculino, con lesiones eritematopapulosas en región de las manos que fue extendiéndose a todo el cuerpo y cuero cabelludo que al desaparecer quedaban manchas hipercrómicas con signo de Darier positivo. Se confirmó el diagnóstico de urticaria pigmentosa mediante biopsia de la piel. Es una enfermedad rara con una baja incidencia, la forma cutánea tiene un pronóstico favorable, por lo que resulta de vital importancia conocer y diagnosticar de forma precoz esta entidad con un manejo multidisciplinario para prevenir las manifestaciones sistémicas que aparecen. Llevar un tratamiento sintomático permitirá una mejor calidad de vida en los infantes. Se presenta el caso porque al considerarse la mastocitosis una enfermedad rara la prevalencia e incidencia de estos casos es muy baja.


Chronic cutaneous mastocytosis is a genodermatosis of unknown etiology and that is within the group of rare or infrequent diseases. They are characterized by the growth and accumulation of mast cells in the skin and other organs of unknown cause and manifest as urticaria pigmentosa. The case of a male patient is presented, with erythematopapular lesions in the region of the hands that spread to the entire body and scalp that, when they disappeared, left hyperchromic spots with Darier's sign: positive. The diagnosis of urticaria pigmentosa was confirmed by skin biopsy. It is a rare disease with a low incidence, the cutaneous form has a favorable prognosis, so it is of vital importance to know and diagnose this entity early with a multidisciplinary management to prevent the systemic manifestations that appear. Taking a symptomatic treatment will allow a better quality of life in infants. The case is presented because mastocytosis is considered a rare disease, the prevalence and incidence of these cases is very low.

ABSTRACT

ABSTRACT Background Reduced or null expression of E-cadherin protein is a frequent cause of diffuse gastric cancer (DGC). More than 50% of patients with DGC present somatic variants in CDH1 gene. Objectives The objectives of this study were to study E-cadherin expression and identify variants in the CDH1 gene in gastric tumors of patients with DGC. Methods We studied 18 Mexican DGC patients who attended a hospital of the Mexican Social Security Institute; E-cadherin expression was determined by immunohistochemistry, and variants were identified by Sanger sequencing in promoter and coding regions. Predictive analysis was performed using PolyPhen-2 and HOPE software. Results We found that 56% of DGC patients showed reduced expression of E-cadherin. All patients carried CDH1 variants; overall, 12 different CDH1 variants were identified. Predictive analysis revealed that the rs114265540 variant was probably damaging, with a value of 0.985, indicating a functional impact on the E-cadherin protein. Variants rs34939176 and rs33964119 were identified as risk factors for DGC (odds' ratios [OR] = 31.3, 95% CI 6.3-154.0, p < 0.001; OR = 6.1, 95% CI 2.0-19.0, p < 0.001, respectively) given their elevated frequency and by comparing it with those reported for MXL population in the 1000 Genomes Project database. Conclusions In this Mexican population, the percentage of diffuse gastric tumors with reduced expression of E-cadherin was similar to that reported in other populations. All gastric tumors of DGC patients studied had somatic CDH1 gene variants; however, the rs114265540, rs34939176, and rs33964119 variants were importantly related to DGC.

ABSTRACT

Introducción: Las fórmulas para la estimación de la tasa de filtración glomerular son fundamentales para estimar el curso de enfermedades renales; incluso ha sido de gran ayuda para obtener datos de prevalencia. Las ecuaciones comparadas con otros métodos son una forma económica y rápida para dar una estimación de la función renal. Objetivo: Describir la utilización de diferentes fórmulas para calcular la tasa de filtración glomerular relacionada con la hipertensión arterial y otras patologías renales y cardiovasculares. Metodología: Se realizó la búsqueda de artículos de investigación en bases de datos como PubMed, Science-Direct, Embase y otras, se estableció un tiempo de publicación entre los años 2018-2022 y se seleccionaron 42 artículos científicos relacionados con el tema. Resultados: La hipertensión arterial es una situación que incrementa el riesgo tanto de enfermedad cardiovascular como de deterioro de la función renal, por lo que en los pacientes hipertensos se espera una relación estrecha en la expresión de ambas patologías. Existen factores que alteran los valores de la creatinina sérica como la dieta, el ejercicio, la edad, el género, la masa muscular, enfermedades musculares y medicamentos. El impacto de la hipertensión en la función renal está descrito además de la relación entre el deterioro de la función renal y el incremento del riesgo cardiovascular; es por esto que en los últimos años la estimación de la función renal se ha incorporado como un marcador de morbilidad y mortalidad cardiovascular. Conclusiones: La estimación de la tasa de filtración glomerular es importante en varios contextos clínicos, en especial en aquellos pacientes con enfermedades que afectan la función glomerular, la creatinina es el biomarcador más usado a pesar de sus evidentes limitaciones.


Introduction: Formulas for estimating glomerular fil-tration rate are fundamental for estimating the course of renal diseases; they have even been of great help in obtaining prevalence data. Equations compared with other methods are an economical and fast way to give an estimation of renal function. Objective: Describe the use of different formulas to calculate the glomerular filtration rate related to high blood pressure and other kidney or cardiovascular pa-thologies. Methodology: Research articles were searched in da-tabases such as PubMed, Science-Direct, Embase and others, a publication time was established between the years 2018-2022 and 42 scientific articles related to the topic were selected. Results: Arterial hypertension is a situation that in-creases the risk of both cardiovascular disease and re-nal function deterioration, so in hypertensive patients a close relationship in the expression of both pathologies is expected. There are factors that alter serum creati-nine values such as diet, exercise, age, gender, muscle mass, muscle diseases and medications. The impact of hypertension on renal function has been described in addition to the relationship between the deterioration of renal function and the increase in cardiovascular risk; this is why in recent years the estimation of renal func-tion has been incorporated as a marker of cardiovascu-lar morbidity and mortality. Conclusions: The estimation of glomerular filtration rate is important in several clinical contexts, especia-lly in those patients with diseases that affect glomerular function; creatinine is the most widely used biomarker despite its obvious limitations

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to assess the rate of repeated pregnancy in adolescence and its association with early marriage and education level. METHODS: This is a cross-sectional study conducted by searching the Live Births Data System. The study included all adolescents in the age group 10-19 years with live births from 2015 to 2019 (n=2,405,248), divided into three groups: G1: primiparas; G2: with 1 previous pregnancy; and G3: with two or more previous pregnancies. RESULTS: Total repeated pregnancies remained stable, along the years. In the age group 10-14 years, the decrease in the period was from 5.0 to 4.7%, whereas in the age group 15-19 years, it was from 27.8 to 27.3%. Being married or in a stable union increases by 96% the chance of repeated pregnancy in the age group 10-14 years (p<0.001; OR=1.96; 95% confidence interval [CI] 1.85-2.09). In the age group 15-19 years, the chance of repeated pregnancy among the married or in stable union increased 40% (p<0.001; OR=1.40; 95%CI 1.39-1.41)). Girls aged 10-14 years with an education level of<8 years had a 64% higher chance of repeated pregnancy (p<0.001; OR=1.64; 95%CI 1.53-1.75), and among those aged 15-19 years, there was a 137% higher chance of repeated pregnancy (p<0.001; OR=2.37; 95%CI 2.35-2.38). CONCLUSION: Repeated pregnancy in adolescence in Brazil remains very high over the years. There is an association between low education level and early marriage with repeated pregnancies in adolescence.

ABSTRACT

ABSTRACT This work analyzes the electrical impedance (EI) measurement of cervical mucus (CM) using a device to determine the fertile window. In this prospective and longitudinal study, fourteen healthy women aged 18 to 44 were enrolled to evaluate three menstrual cycles. EI was measured through a medical device inserted into the vagina for two minutes daily. Patients were monitored by urine luteinizing hormone (LH) strip, blood collection, and vaginal ultrasound to visualize the dominant follicle. Finally, the predictive EI capacity was validated by the receiver operating characteristic (ROC) of anovulatory vs. ovulatory impedances. The peak of LH was 35.7 (±4.5) mUI/ml and the dominant follicle size was 15.45 mm (±0.559). There were statistical differences in EI measurements between the follicular and luteal phases vs. the ovulation phase (p<0.0361 and p<0.0160). After data normalization, an area under the ROC curve (AUC) of 0.713 (P value= 0.0253), a Youden J index of 0.4545Ω, a sensitivity of 63.6%, and a specificity of 81.8% were found. Low EI in the ovulatory period belongs to the LH ovulatory peak and follicular release. EI can be used for ovulation monitoring, birth control, or promoting pregnancy as a safe and innocuous method.


RESUMEN Este trabajo analiza la medición de la impedancia eléctrica (IE) del moco cervical (MC) mediante un dispositivo para determinar la ventana fértil. En este estudio prospectivo y longitudinal, se incluyeron 14 mujeres sanas de 18 a 44 años para evaluar tres ciclos menstruales. La IE se midió a través de un dispositivo médico colocado en la vagina durante dos minutos diarios. Las pacientes fueron monitoreadas con una tira de hormona luteinizante (LH) en orina, recolección de sangre y ultrasonido vaginal para visualizar el folículo dominante. Finalmente, la capacidad predictiva de IE fue validada por la curva ROC (receiver operating characteristic) de impedancias anovulatorias vs. ovulatorias. El pico de LH fue de 35.7(±4.5) mUI/ml; el folículo de tamaño dominante fue de 15.45 mm (±0.559). Se encontraron diferencias estadísticas para la medición de la IE de las fases folicular y lútea versus la fase de ovulación (p<0.0361 y p<0.0160). Después de la normalización de los datos, se encontró un área bajo la curva ROC (AUC) de 0.713 (valor de P = 0.0253), un índice de Youden J de 0.4545 Ω, sensibilidad del 63.6 % y especificidad del 81.8 %. La IE baja en el período ovulatorio que pertenece al pico ovulatorio de LH y liberación folicular. La IE se puede utilizar para el control de la ovulación, el control de la natalidad o la promoción del embarazo como método seguro e inocuo.

ABSTRACT

Introdução: A incontinência urinária (IU) é um problema muitas vezes subestimado, não recebendo a devida atenção. Dentre as possibilidades de tratamento conservador da IU, o treinamento dos músculos do assoalho pélvico (TMAP) supervisionado deve ser recomendado como primeira linha de tratamento para as mulheres. O TMAP pode ser desenvolvido em grupos, individualmente e em casa. Objetivos: Ainda há poucos estudos na literatura envolvendo TMAP em grupo com protocolos definidos que possam ser facilmente compreendidos e reproduzidos pelos pacientes. O objetivo deste estudo é demonstrar a eficácia de um protocolo de TMAP em grupo comparado a um protocolo de TMAP domiciliar para mulheres com IU. Métodos: Este foi um estudo experimental controlado randomizado cego que seguiu as recomendações do CONSORT. Os instrumentos de avaliação foram a escala PERFECT, ICIQ-SF e PISQ-12. O principal resultado foi a melhora da função dos músculos do assoalho pélvico (MAP) e os resultados secundários foram a melhora da qualidade de vida (QV) e da função sexual (FS). Resultados: Com doze semanas de tratamento o protocolo do grupo TMAP apresentou-se como uma forma de tratamento mais eficaz para IU, pois apresentou melhora nos itens potência e QV. Ao observar a efetividade dos protocolos, após vinte e quatro semanas, ambos foram efetivos apenas no que se refere aos desfechos secundários, QV e FS. Conclusão: Pode-se supor que a intervenção em grupo, utilizada nesta amostra específica, constitui uma estratégia de intervenção fisioterapêutica factível e viável, capaz de beneficiar muitas mulheres com IU, além de ser uma ferramenta de fácil compreensão e acompanhamento pelos pacientes.

Métodos: se realizó un estudio observacional, descriptivo y transversal en gestantes atendidas en el Hospital General Docente "Abel Santamaría Cuadrado" entre mayo de 2018 y marzo de 2021. La muestra quedó conformada por 26 pacientes. Se empleó estadística descriptiva. Resultados: el 0,09 % de las 27 500 gestantes atendidas presentaronenfermedad tromboembólica venosa, conmayorincidenciaen el grupo etario de gestantes de 35 años o más (0,06 %). El 76,92 % desarrolló la enfermedad tromboembólica venosa durante elpuerperio, la mayor incidencia durante el puerperio se observó en pacientes sometidas a cesárea (80 %). El 57,69 % de las pacientes conenfermedad tromboembólica venosa durante la gestaciónpresentaronvárices en miembros inferiores y el 69,23 % refirieron antecedentes de trombosis venosa profunda. La enfermedad tromboembólica venosa fuecomún (57,69 %) en gestantes con un índice de masa corporal mayor de 28,6. Conclusiones: el tromboembolismo venoso presentó una baja incidencia, la cualfuemayor durante elpuerperio, se presentócomúnmente en esa etapa en aquellas que fuenecesariorealizarles cesárea. En las gestantes con antecedentes de trombosis venosa profunda fuecomún la recurrencia. La enfermedad tromboembólica venosa fue más frecuente en gestantes conun índice de masa corporal elevado.


ABSTRACT Introduction: venous thromboembolic disease constitutes one of the complications of pregnancy, which can evolve torpidly and cause death. Objective: to characterize pregnant women with venous thromboembolic disease attended at the "Abel SantamaríaCuadrado" General Teaching Hospital. Methods: an observational, descriptive and cross-sectional study was conducted in pregnant women attended at the "Abel SantamaríaCuadrado" General Teaching Hospital between May 2018 and March 2021. The sample consisted of 26 patients. Descriptive statistics were used. Results: 0,09 % of the 27,500 pregnant women attended presented venous thromboembolic disease, with a higher incidence in the age group of pregnant women aged 35 years or older (0,06 %). A total of 76,92 % developed venous thromboembolic disease during the puerperium, with the highest incidence during the puerperium being observed in patients who underwent cesarean section (80 %). Of the patients with venous thromboembolic disease during pregnancy, 57,69% presented varicose veins in the lower limbs and 69,23 % reported a history of deep vein thrombosis. Venous thromboembolic disease was common (57,69 %) in pregnant women with a body mass index greater than 28,6. Conclusions: Venous thromboembolism presented a low incidence, which was higher during the puerperium, occurring commonly at that stage in those who had to undergo cesarean section. In pregnant women with a history of deep vein thrombosis, recurrence was common. Venous thromboembolic disease was more frequent in pregnant women with a high body mass index.

ABSTRACT

Introducción: Los exosomas son vesículas extracelulares de tamaño nanométrico, que se generan cuando los endosomas multivesiculares se fusionan con la membrana plasmática y el contenido de las vesículas intraluminales se libera en el espacio extracelular. Son producidos por casi todos los tipos de células, en condiciones fisiológicas y patológicas. Transportan proteínas, lípidos y ácido ribonucleico (ARN) no codificante, desde la célula madre hasta la célula receptora, estos son considerados un punto clave en la regeneración de tejidos, lo que se ha demostrado en una serie de estudios, con diferentes tejidos corporales, como piel, cartílago, pancreático y tejidos cardiovasculares. Objetivo: Explicar los aspectos generales y posibles usos de los exosomas en el campo médico. Métodos: Se realizó una búsqueda de información mediante consulta en las bases de datos SciELO PubMed, Science Direct y Lilacs, en los idiomas español e inglés, con diferentes combinaciones de palabras claves y términos MESH como: exosomes, neovascularization, wound healing, immunity, micro RNA, immunology, therapy, classification. Se efectuó un análisis y resumen de la información revisada. Conclusiones: En la actualidad, los exosomas se han convertido en objeto de investigación para diversos tratamientos, medicamentos y uso como marcadores moleculares. Se destacan en terapias contra el cáncer, la inmunomodulación, la estimulación o supresión de la angiogénesis, regeneración cutánea, cicatrización y curación de heridas; por lo que de forma general resultan prometedores en el ámbito de las ciencias médicas(AU)


Introduction: Exosomes are nano-sized extracellular vesicles, which are generated when multivesicular endosomes fuse with the plasma membrane and the content of intraluminal vesicles released into the extracellular space. Are produced by almost all types of cells, under physiological and pathological conditions and they transport proteins, lipids and non-coding RNA (ribonucleic acid), from the stem cell to the recipient cell, these are considered a key point in tissue regeneration, which has been shown in a series of studies, with different body tissues, such as skin, cartilage, pancreatic and cardiovascular tissues. Objective: To explain the general aspects and possible uses of exosomes in the medical field. Methods: A search for information was carried out by consulting the Scielo, PubMed, ScienceDirect and Lilacs databases, in Spanish and English, with different combinations of keywords and MESH terms such as: exosomes, neovascularization, wound healing, immunity, microRNA, immunology, therapy, classification. Then, an analysis and summary of the reviewed information was carried out. Conclusions: Currently, exosomes have become the object of research for various treatments, drugs, and their use as molecular markers. They stand out in cancer therapies, immunomodulation, stimulation or suppression of angiogenesis, skin regeneration, and wound healing, which is why they are generally promising in the field of medical sciences(AU)

ABSTRACT

El quiste paraovárico se desarrolla en el ligamento ancho, entre la trompa de Falopio y el ovario. Son estructuras redondeadas de pared lisa, llenas de líquido seroso, que se ubican en el mesosálpinx, el ligamento ancho o sobre la propia trompa uterina. Tienen una incidencia aproximada de 1 en 1 500 0002 son frecuentes en la tercera y cuarta década de la vida; raramente se presentan en la edad pediátrica. Generalmente, son benignos y tiene un crecimiento lento y progresivo, suelen ser asintomáticos por lo que el diagnóstico suele ser incidental. En casos de quistes de gran volumen, los síntomas son dolor pélvico o la tumoración ab-dominal. Usualmente son diagnosticados clínicamente y se confirman por imágenes ultrasonográficas. La importancia de este caso es la poca frecuencia de estos tumores en la edad pediátrica y su identificación oportuna por parte de los profesionales de la salud


The paraovarian cyst develops in the broad ligament, between the fallopian tube and the ovary. They are rounded structures with a smooth wall, filled with serous fluid, which are located in the mesosalpinx, the broad ligament or on the uterine tube itself. They have an approximate incidence of 1 in 1,500,0002 and are common in the third and fourth decades of life; they rarely occur in childhood. Generally, they are benign and have a slow and progressive growth, they are usually asymptomatic, so the diagnosis is usually incidental. In cases of large volume cysts, the symptoms are pelvic pain or abdominal mass. They are usually diagnosed clinically and confirmed by ultrasonographic images. The importance of this case is the infrequency of these tumors in the pediatric age and their timely identification by health professionals

ABSTRACT

Introduction For low-risk prostate cancer (PCa), curative treatment with radical prostatectomy (RP) can be performed, reporting a biochemical relapse-free survival rate (bRFS) at 5 and 7 years of 90.1% and 88.3%, respectively. Prostatic specific antigen (PSA), pathological stage (pT), and positive margins (R1) are significant predictors of biochemical relapse (BR). Even though pelvic lymphadenectomy is not recommended during RP, in the literature, it is performed in 34% of these patients, finding 0.37% of positive lymph nodes (N1). In this study, we aim to evaluate the 10-year bRFS in patients with low-risk PCa who underwent RP and extended pelvic lymph node dissection (ePLND). Methodology All low-risk patients who underwent RP plus bilateral ePLND at the National Cancer Institute of Colombia between 2006 and 2019 were reviewed. Biochemical relapse was defined as 2 consecutive increasing levels of PSA > 0.2 ng/mL. A descriptive analysis was performed using the STATA 15 software (Stata Corp., College Station, TX, USA), and the Kaplan-Meier curves and uni and multivariate Cox proportional hazard models were used for the survival outcome analysis. The related regression coefficients were used for the hazard ratio (HR), and, for all comparisons, a two-sided p-value ˂ 0.05 was used to define statistical significance. Results Two hundred and two patients met the study criteria. The 10-year bRFS for the general population was 82.5%, statistically related to stage pT3 (p = 0.047), higher Gleason grade group (GG) (p ≤ 0.001), and R1 (p ≤ 0.001), but not with N1. A total of 3.9% of the patients had N1; of these, 75% had R1, 25% GG2, and 37% GG3. Among the N0 (non-lymph node metástasis in prostate cáncer) patients, 31% of the patients had R1, 41% GG2, and 13% GG3. Conclusions Our bRFS was 82.5% in low-risk patients who underwent RP and ePLND. With higher pT, GG, and presence of R1, the probability of BR increased. Those with pN1 (pathologicaly confirmed positive lymph nodes) were not associated with bRFS, with a pN1 detection rate of 3.9%. Details: In low-risk PCa, curative treatment with RP can be performed, reporting a bRFS rate at 5 and 7 years of 90.1% and 88.3%, respectively. Despite the fact that pelvic lymphadenectomy is not recommended during RP in clinical guidelines, in the literature, it is performed in 34% of these patients, finding 0.37% of N1. In this study, we report the 10-year bRFS in patients with low-risk PCa who underwent surgery.


Introducción En el cáncer de próstata (CaP) de bajo riesgo se puede realizar un tratamiento curativo mediante prostatectomía radical (PR), con una tasa de supervivencia libre de recaída bioquímica (SLRb) a 5 y 7 años del 90,1% y el 88,3%, respectivamente. El antígeno prostático específico (PSA), el estadio patológico (pT) y los márgenes positivos (R1) son predictores significativos de recaída bioquímica (BR). Aunque la linfadenectomía pélvica no está recomendada durante la PR, en la literatura se realiza en el 34% de estos pacientes, encontrándose un 0,37% de ganglios linfáticos positivos (N1). En este estudio, nuestro objetivo es evaluar la SLB a 10 años en pacientes con CaP de bajo riesgo sometidos a PR y disección ganglionar pélvica extendida (DGLPe). Metodología Se revisaron todos los pacientes de bajo riesgo sometidos a PR más ePLND bilateral en el Instituto Nacional de Cancerología de Colombia entre 2006 y 2019. La recaída bioquímica se definió como 2 niveles crecientes consecutivos de PSA > 0,2 ng/mL. Se realizó un análisis descriptivo utilizando el software STATA 15 (Stata Corp., College Station, TX, USA), y se utilizaron las curvas de Kaplan-Meier y los modelos uni y multivariados de riesgos proporcionales de Cox para el análisis de resultados de supervivencia. Los coeficientes de regresión relacionados se utilizaron para la hazard ratio (HR), y, para todas las comparaciones, se utilizó un valor p de dos caras ˂ 0,05 para definir la significación estadística. Resultados Doscientos dos pacientes cumplieron los criterios del estudio. La bRFS a 10 años para la población general fue del 82,5%, estadísticamente relacionada con el estadio pT3 (p = 0,047), mayor grupo de grado Gleason (GG) (p ≤ 0,001), y R1 (p ≤ 0,001), pero no con N1. Un total del 3,9% de los pacientes tenían N1; de ellos, el 75% tenían R1, el 25% GG2, y el 37% GG3. Entre los pacientes N0 (metástasis no ganglionar en el cáncer de próstata), el 31% de los pacientes tenían R1, el 41% GG2 y el 13% GG3. Conclusiones Nuestra SSEb fue del 82,5% en los pacientes de bajo riesgo que se sometieron a RP y ePLND. A mayor pT, GG y presencia de R1, mayor probabilidad de RB. Aquellos con pN1 (ganglios linfáticos patológicamente confirmados como positivos) no se asociaron con la SSEb, con una tasa de detección de pN1 del 3,9%. Detalles: En el CaP de bajo riesgo se puede realizar tratamiento curativo con PR, reportando una tasa de SSEb a 5 y 7 años de 90,1% y 88,3%, respectivamente. A pesar de que la linfadenectomía pélvica no está recomendada durante la PR en las guías clínicas, en la literatura se realiza en el 34% de estos pacientes, encontrando un 0,37% de N1. En este estudio, reportamos la SLB a 10 años en pacientes con CaP de bajo riesgo sometidos a cirugía.
