Abstract Objective Takayasu arteritis (TAK) is a rare chronic granulomatous vasculitis that affects large vessels and usually begins in women of childbearing age, so it is not uncommon for pregnancies to occur in these patients. However, there is limited information about these pregnancies, with reports of adverse maternal and obstetric outcomes. The objective of this study is to evaluate adverse maternal, fetal and neonatal events in pregnant patients with TA. Methods This is a cross-sectional study with retrospective data collection. We reviewed 22 pregnancies in 18 patients with TAK, according to the American College of Rheumatology criteria, that were followed up in a high-risk prenatal clinic specialized in systemic autoimmune diseases and thrombophilia (PrAT) at Hospital Universitário Pedro Ernesto, from 1998 to 2021. Results In twenty-two pregnancies, the mean age of patients was 28.09 years and the mean duration disease was 10.9 years. Of the 18 patients with TAK studied, only one had the diagnosis during pregnancy and had active disease. All other patients had a previous diagnosis of TAK and only 3 had disease activity during pregnancy. Twelve patients (66.6%) had previous systemic arterial hypertension and eleven (61.1%) had renal involvement. Among maternal complications, eight patients (36.3%) developed preeclampsia and six (27.2%) had uncontrolled blood pressure without proteinuria, while 10 (45%) had puerperal complications. Four (18.1%) births were premature, all due to severe preeclampsia and eight newborns (34.7%) were small for gestational age. When all maternal and fetal/neonatal outcomes included in this study were considered, only 6 (27.2%) pregnancies were uneventful. Conclusion Although there were no maternal deaths or pregnancy losses in this study, the number of adverse events was considerably high. Hypertensive disorders and small for gestational age newborns were more common than general population, while the number of patients with active disease was low. These findings suggest that pregnancies in patients with TAK still have several complications and a high-risk prenatal care and delivery are necessary for these patients.

Abstract This work presents a mother with a child diagnosed with ASD, following a qualitative single case methodological design. The data were collected through the semi-structured in-depth interview technique, whose content was analyzed and organized into seven categories that expose the experience and highlight the resources developed by the mother as determining factors of resilience. The results ensure that life and family experiences around ASD have been a driving force to move forward. Findings from other previous studies are also shared that highlight family work that favors the resilient characteristics of the mother and that could permeate the whole family.

Resumen Este trabajo presenta una madre con un hijo con diagnóstico TEA, siguiendo un diseño metodológico de corte cualitativo de caso único. Los datos fueron recolectados a través de la técnica de entrevista semiestructurada a profundidad, cuyo contenido fue analizado y organizado en siete categorías que exponen la vivencia y resaltan los recursos desarrollados por la madre como factores determinantes de resiliencia. Los resultados permiten asegurar que las experiencias de vida y familia en torno al TEA han sido un motor de impulso para salir adelante. Se comparten también hallazgos de otros estudios previos que resaltan el trabajo familiar que favorecen las características resilientes de la madre y que pudieran permear a toda la familia.

Resumen La sororidad engloba las prácticas de colaboración y soporte en las relaciones entre mujeres y es el espacio propicio para la construcción de nuevas formas de significar la vejez femenina. El objetivo de este estudio cualitativo fue describir y categorizar los tipos de configuraciones vinculares que se mantienen y los que se han transformado en pro a la sororidad en los procesos de envejecimiento femenino, por medio del análisis narrativo de una entrevista profunda grupal. Los resultados muestran la necesidad de implementar políticas y acciones en aras de disminuir el ageism con relación al envejecimiento de mujeres. La construcción de la sororidad ayuda en el empoderamiento colectivo en pro de su género. La sexualidad de la mujer mayor sigue siendo un tema pendiente en la agenda de la investigación y la discusión en los estudios feministas, lo que nos lleva a concluir que, a pesar de la existencia de diferencias individuales en los propios procesos de envejecimiento, las mujeres se experimentan y comparten en una misma condición histórica, por ello es en colectivo que la acción de la sororidad se pronuncia como vía en la generación de nuevas narrativas preferidas por las mujeres. Finalmente, se expone una propuesta para trabajar la percepción del cuerpo femenino en el proceso de envejecer, y la construcción de la sororidad, desde las prácticas narrativas de White y Epston.

Abstract Sorority encompasses the practices of collaboration and support in relations between women and is the propitious space for the construction of new ways to signify female old age. We present results of a qualitative study using focus groups, which aimed to describe and categorize the types of relational configurations that remain unchanged or change towards sorority in the female aging process. Findings describe the need to implement actions to reduce ageism, not only in terms of the experiences women go through, but also towards aging in general. One of the measures we can take is undoubtedly the construction of women circle sorority, which leads to collective empowerment of gender. The female body is a focus of attention in terms of what it lives and experiences, and the right to have love and sexuality throughout life is also highlighted. We then created an intervention proposal to work on the perception of the female body and its experience in the aging process. The proposed intervention is a workshop, based on the narrative model of Michael White and David Epston.

The area of channels and fjords belonging to the Magellan subantarctic has a high diversity of macroalgae, in relation to the temperate areas of South America. Geomorphological changes, the geographical position in a high latitude together with the climate change in this region create a series of coast marine habitats with a significant environmental heterogeneity, where a diverse benthic marine flora take place, which are not still known, that has evolved in an adaptive way to these changes. This research was developed under the 16 fjords CIMAR program in 2010, aboard the scientific research vessel Abate Molina, under the "Marine Benthic macroalgae of the Region of Magallanes and Chilean Antarctica" project. This paper gives information about a total of 57 species of macroalgae in the region, with representatives of the Rhodophyta (51%), Ochrophyta (Class Phaeophyceae) (37%) and Divisions Chlorophyta (12%). Takes into account the floristic affinities of the sectors studied and deals with the flora of the Antarctic continent, and also incorporates 7 novel macroalgal references to the subantarctic Magellan ecoregion.

La zona de canales y fiordos subantárticos de Magallanes, presenta una alta diversidad de macroalgas, respecto a las zonas templadas del sur de Sudamérica. Sus cambios geomorfológicos, su posicionamiento geográfico de alta latitud y sus cambios estacionales, crean en esta región una serie de hábitats marino-costeros con una importante heterogeneidad ambiental donde ocurre una diversa flora marina bentónica. Esta biota ha evolucionado de manera adaptativa a estos cambios y requiere ser investigada. El presente estudio fue desarrollado en el marco del programa CIMAR fiordos 16 realizado el año 2010 a bordo de la nave de investigación científica Abate Molina. Se realizaron muestreos mediante buceo autónomo sobre la diversidad de macroalgas, en 17 sitios de los canales y fiordos magallánicos. Un total de 57 especies de macroalgas fueron recolectadas e identificadas para la región, con representantes de las Divisiones Rhodophyta (51%) Ochrophyta (Clase Phaeophyceae) (37%) y Chlorophyta (12%). Se abordan las afinidades florísticas de los sectores estudiados y con la flora del continente antártico. Se registran 7 nuevos taxa para la eco-región subantártica de Magallanes.

A continuous culture of Spirulina (Arthrospira platensis) was performed for 78 in a tubular photobioreactor of 300 L volume. During this period there was growth in biomass and crop response to the strategy of adding the nutrient medium. Using as a basis the modified Zarrouk medium, three nutritive combinations were elaborated: initial medium (MI), growth medium (SA1+SA2) and maintenance medium (SB1+SB2) for different crop stages. The media delivery is affected gradually and in accordance with requirements of growing biomass (dry weight) daily cultivation. The initial crop biomass was 2.0 g L-1, on day 20 of culture was made the first partial harvest (50%) starting a new stage of the crop with an initial biomass of 1.7 g L-1' 20 days after a second crop was partially culture initiating a third culture step with a biomass of 1.6 g L-1. The results obtained after harvest were, on the average, 3.7; 4.1 and 9.7 g L-1 respectively. The proximal analysis was performed at the end of the continuous cultivation showed a 71.6% of protein content.

Se realizó un cultivo continuo de Spirulina (Arthrospira platensis) durante 78 días en un fotobiorreactor tubular de 300 L de volumen. Durante este periodo se registró el crecimiento en biomasa y la respuesta del cultivo a la estrategia de adición del medio nutritivo. Utilizando como base el medio Zarrouk modificado, se elaboraron tres medios: medio inicial (MI), medio crecimiento (SA1+SA2) y medio mantenimiento (SB1+SB2) para las distintas etapas del cultivo. La entrega de los medios se efectuó paulatinamente y de acuerdo a los requerimientos del crecimiento en biomasa (en peso seco) diario del cultivo. La biomasa inicial del cultivo fue de 2,0 g L-1, al día 20 se efectuó la primera cosecha parcial (50%) dando inicio a una nueva etapa del cultivo con una biomasa inicial de 1,7 g L-1, 20 días después se realizó una segunda cosecha parcial del cultivo, iniciando una tercera etapa de cultivo con una biomasa de 1,6 g L-1. Los resultados obtenidos al cabo de las cosechas fueron, en promedio, de 3,7; 4,1 y 9,7 g L-1, respectivamente. El análisis proximal efectuado al final del cultivo continuo indicó un 71,6% de proteína.

This paper is a compilation of data from investigations made with marine benthic algae from the Magellan Region that have biotechnological utilization in human consumption or medicine or as a source of phycolloids or food supplements or animal feed. The most important Rhodophyta species are: Ahnfeltia plicata (Hudson) E.M. Fries for agarose production, Gigartina skottsbergii Setchell & N.L.Gardner for carrageenan production, and Callophyllis variegata (Bory de Saint-Vincent) Kützing for human consumption. The most important Heterokontophyta species are: Macrocystis pyrifera (L.) C. Agardh, and Durvillaea antarctica (Chamisso) Hariot for human consumption, alginate production, and as biofertilizer for agricultural crops. M. pyrifera is also used as a food supplement for salmon, chickens, quails, sheep and bovines and for biofuel production.

The exploitation of seaweeds in Chile has been carried out for more than 60 years. More recently, seaweeds have been used for the production of alginate, agar and carrageenan, agricultural fertilizers and industrial aquaculture (feed for abalone and sea urchins), increasing the added value of this natural resource. In the Magellan Region (56ºS), the giant kelp Macrocystis pyrifera (L.) C. Agardh presents the most extensive kelp forest, reaching a biomass of approximately 12 kg.m-2. Recent studies have shown potential benefits from adding M. pyrifera- derived flour to salmonid feed. Research is currently underway to evaluate the useof brown algae-derived products for marine aquaculture feed of Oncorhynchus mykiss in tanks. There was no apparent adverse effect on the evaluated parameters that can be attributed to the incorporation of M. pyrifera meal in the diets fed to salmonids. Even when the control diet had numerically the best performance in zootechnical terms, the analysis of variance of all parameters evaluated showed no significant differences with regard to diets containing M. pyrifera meal. These results demonstrated that seaweed meal has important benefits for animal health and nutrition that could be applied or tested in other marine organisms of commercial importance.
