ABSTRACT The development of aquaculture through the cultivation of what are considered unconventional species is an option with the potential to solve the problem of food scarcity. The aim of the present study was to evaluate the zootechnical performance of juvenile Pomacea haustrum fed different commercial diets, and subjected to different levels of salinity. After seven P. haustrum spawn had hatched in the laboratory, the juveniles were randomly selected and transferred to the rearing containers. Two different commercial diets were offered: rabbit feed with a high proportion of ingredients rich in crude vegetable protein (VP), and dog food containing balanced levels of ingredients rich in crude vegetable and animal protein (MP). The selected juveniles were randomly stocked at different salinities (0, 2 and 4 parts per thousand - ppt). The experiment lasted 65 days. Twenty-one hours after the start of the experiment, 100% of the individuals reared at a salinity of 4 ppt had died. There was a significant difference (p ≤ 0.05) between the results for zootechnical performance (average final weight, weight gain, average final growth, specific growth rate, protein efficiency and apparent feed conversion) for animals reared in fresh water or at a salinity of 2 ppt, regardless of the type of diet. The origin of the protein in the diet had no significant effect on the zootechnical performance of the individuals; however, the salinity of the water impaired development of the animals in direct proportion to its concentration. scarcity P laboratory containers offered VP, VP , (VP) MP.

ABSTRACT In response to global concerns over food scarcity, the sweet potato (Ipomoea batatas (L.) Lam) has emerged as a promising alternative due to its rich composition of carbohydrates (starch), protein, fiber, vitamins, and minerals. This study aims to assess the physicochemical characteristics and nutritional content of different sweet potato landraces cultivated in Yucatan, Mexico. The study involved the evaluation of eight landraces of sweet potato cultivated in traditional farming systems, assessing both physicochemical and proximate composition variables, and determining the starch yield, starch color, protein content, swelling degree, and starch solubility index. The sweet potato landraces showed values ranging from acidic to slightly neutral pH (6-6.4). The yellow sweet potato II, purple sweet potato, and pink sweet potato landraces displayed high levels of total soluble solids with a range of 12.5 to 14.33 °Brix. Significant differences were observed in both peel and root pulp coloration. The pink, yellow, purple I, mamey, yellow II, and purple sweet potato landraces, presented elevated percentages of carbohydrates (85.0% to 89.0%), fats (1.1% to 1.5%), protein (3.5% to 5.1%), fiber (4.0% to 5.0%), and ash (3.5% to 4.0%). The mamey sweet potato and pink sweet potato landraces showed higher starch yields. Swelling power and starch solubility index peaked at a temperature of 90 °C. These results highlight the significance of sweet potato landraces cultivated in Yucatan as a valuable genetic resource with nutritional potential, which can be included in the diet of people, genetic improvement and species conservation programs.

Abstract Frailty, defined as an inappropriate response to stressful situations due to the loss of physiological reserve, was initially described in the elderly population, but is currently being identified in younger populations with chronic diseases, such as chronic kidney disease. It is estimated that about 20% of patients are frail at the time of kidney transplantation (KT), and there is great interest in its potential predictive value for unfavorable outcomes. A significant body of evidence has been generated; however, several areas still remain to be further explored. The pathogenesis is poorly understood and limited to the extrapolation of findings from other populations. Most studies are observational, involving patients on the waiting list or post-KT, and there is a scarcity of data on long-term evolution and possible interventions. We reviewed studies, including those with Brazilian populations, assessing frailty in the pre- and post-KT phases, exploring pathophysiology, associated factors, diagnostic challenges, and associated outcomes, in an attempt to provide a basis for future interventions. Frailty reserve population diseases disease 20 KT, KT , (KT) outcomes generated however explored observational postKT, postKT post longterm long term interventions pre phases pathophysiology factors challenges 2 (KT

Resumo A fragilidade, conceituada como a resposta inadequada a situações de estresse devido à perda da reserva fisiológica, foi descrita incialmente na população idosa, mas atualmente vem sendo identificada em populações mais jovens com doenças crônicas, como a doença renal crônica. Estima-se que cerca de 20% dos pacientes sejam frágeis no momento do transplante renal (TR), e há grande interesse pelo seu potencial valor preditor de desfechos desfavoráveis. Um número expressivo de evidências tem sido gerado, entretanto, ainda persistem várias áreas a serem mais exploradas. A patogênese é pouco conhecida e limitada à extrapolação dos achados de outras populações. A maioria dos estudos é observacional, envolvendo pacientes em lista ou após o TR, e há escassez de dados sobre a evolução em longo prazo e possíveis intervenções.

Resumen En este artículo se analiza un conjunto de noticias televisivas que, durante el segundo bienio del gobierno de Mauricio Macri (2018-2019) en Argentina, informaron sobre distintas medidas regresivas en materia de derechos migratorios a nivel nacional y provincial. Se indaga la mediatización de discursos oficiales y su legitimación para modificar la legislación vigente, así como la difusión de noticias que criminalizan a la población migrante para justificar la implementación de dichas políticas. Ante la escasez de estudios sobre representaciones de migrantes en la televisión, se examina cómo los/as funcionarios/as utilizan la pantalla para allanar el camino para sus decisiones políticas. A partir del análisis del discurso de un corpus de noticias se corrobora, entre otras cosas, una articulación entre discursos mediáticos y políticos, y una brecha informativa sobre los derechos migratorios, todo lo cual redunda en obstáculos para la construcción de una ciudadanía comunicacional de las personas migrantes.

Abstract This article analyzes a set of television news that reported on different regressive measures regarding migration rights at national and provincial levels, aired during the second biennium of Mauricio Macri’s government (2018-2019) in Argentina. Here we delve into the mediatization of official discourses, and their legitimization to modify current legislation, as well as into the dissemination of news that criminalize the migrant population, aimed at justifying the implementation of such policies. Given the scarcity of studies on the representation of migrants on television, this study examines how officials use the screen to pave the way for their political decisions. From the analysis of the discourse conveyed in this corpus of news, is revealed, among other things, an articulation between media and political discourses, and the existence of an information gap on migration rights, all of which results in hurdles for the construction of a communicational citizenship of migrants.

Summary: The state of Chiapas presents degradation processes of dif ferent kinds, as a consequence of the current established agricultural model. It is estimated that, in the near future, the surface of the state of Chiapas will present more than 55% degradation, generating changes in the physical, chemical and biological properties of the soil, af fecting the quality of life of human beings, mainly due to scarcity of food. The objective of this research was to evaluate the quality of the soils in three municipalities of the central depression of Chiapas, Mexico. The analysis were interpreted taking NOM-021-SEMARNAT-2000 as a reference and were classified according to the world reference base (WRB), version 2014. For the evaluation of soil quality, the sustainable use of land subindex (SUSS). 144 soil samples corresponding to 21 profiles were analyzed. Of the 21 profiles studied, 17 present poor soil qualities, two a sensitive quality, one acceptable quality and one with good quality. Only two soil groups presented good fertility and are classified as Vertisols and Phaeozems, which present good quality and capacity to maintain sustainable agricultural production in this region.

Summary: In recent decades, water scarcity has increased considerably in Cuauhtémoc, Chihuahua - the most important apple-growing region of Mexico. Thus, the objective of this research is focused on evaluating growth and development responses in apple rootstocks graf ted with Golden Delicious subjected to four drought cycles, comparing them with the continuous irrigation treatment. Ten rootstocks were evaluated (B.9, M.9Nic29, G.41, G.202, G.890, G.210, G.30, M.7, MM.111 and MM.109) used in the commercial apple orchards in the area, where all the rootstocks were obtained during the 2020 growing season. The planting was carried out in 20-L pots in March 2020 and a substrate composed of compost, soil and sand was used in a ratio of 1:1:1. The recorded variables measured were moisture percentage in the soil, the leading branch growth, leaf water potential, total biomass, and ef ficient water use. The rootstocks B.9 and M.9 Nic29 showed good results in most of the variables studied. Rootstocks with good recovery of leaf water potential af ter recovery irrigation were found. These rootstocks were; B.9, M.9Nic29, MM.111 and G.210. The total biomass was statistically the same in G.30, G.41, MM.111, MM.109, G.202 and B.9. In conclusion, rootstocks tolerate a certain degree of drought and can contribute to improving water use, highlighting B.9.

Resumen: La escasez de agua en la región manzanera más importante de México; Cuauhtémoc, Chihuahua, se ha incrementado considerablemente en las últimas décadas. El objetivo de esta investigación se concentró en evaluar la respuesta en crecimiento y desarrollo de portainjertos de manzano injertados con Golden Delicious, sometidos a cuatro ciclos de sequía, comparándolos con el tratamiento de riego continuo. Se evaluaron 10 portainjertos (B.9, M.9Nic29, G.41, G.202, G.890, G.210, G.30, M.7, MM.111 y MM.109), los cuales son utilizados en las huertas comerciales de manzano de la zona de Cuauhtémoc. Todos los portainjertos se obtuvieron de viveros comerciales durante la estación de crecimiento 2019. La plantación se realizó en macetas de 20 L en el mes de marzo de 2020 y se utilizó un sustrato compuesto por composta, suelo y arena en proporción 1:1:1. Las variables registradas fueron; porcentaje de humedad en el suelo, crecimiento de la rama líder, potencial hídrico de la hoja, biomasa total, y uso eficiente del agua. Los portainjertos B.9 y M.9Nic29 mostraron buenos resultados en la mayoría de las variables estudiadas. Los portainjertos B.9, M.9Nic29, MM.111 y G.210 mostraron buena recuperación del potencial hídrico de la hoja después del riego de recuperación. La biomasa total fue estadísticamente igual en G.30, G.41, MM.111, MM.109, G.202 y B.9.

Resumen Este artículo analiza el rol del Estado en relación con el Programa Hogar y el sentido que las beneficiarias le otorgan. En un inicio concebido como un esquema de asistencia para suplir los problemas de acceso a gas de consumo doméstico mediante la entrega de bombonas en los hogares, el programa devino en una transferencia monetaria directa. Este mecanismo es insuficiente, dado que, en un contexto de escasez y ausencia de empleo formal, las jefas de hogar emplean el dinero para sufragar gastos de la canasta básica. La ineficiencia del Estado, junto con capacidades comunitarias-barriales menoscabadas para visibilizar problemas y hacer demandas, hace que el programa, en realidad, no produzca beneficiarias. En conclusión, el Estado argentino lleva a cabo prestaciones parciales que no cubren las necesidades de los hogares vulnerables; asimismo, la dinámica del Programa Hogar podría cumplir objetivos relevantes si examinase y ajustase su enfoque de derechos.

Abstract This article analyses the role of the Argentinian state concerning the Home Programme and the meaning beneficiaries give to it. Originally conceived as an assistance scheme to overcome problems of access to gas for domestic consumption through the delivery of gas cylinders to households, the programme became a direct monetary transfer. In a context of scarcity and lack of formal employment, the mechanism is insufficient given that female heads of household use the money to cover basic food basket expenses. The inefficiency of the state and the undermining of community and neighbourhood capacities to make problems visible and make demands would mean that the programme does not produce beneficiaries. In conclusion, the state carries out partial benefits that do not cover the needs of vulnerable households; likewise, the "Home Programme" dynamics could fulfil relevant objectives if it examines and adjusts its focus on rights.

Resumen El alquiler de vivienda es una práctica en crecimiento en gran parte de Argentina. Este trabajo analiza el proceso de inquilinización y las iniciativas de regulación del mercado de alquileres en Rosario, tercera ciudad con mayor número de inquilinos del país entre 2003-2023. Los datos que arrojan los documentos oficiales, no oficiales y notas de prensa, muestran que la legislación nacional favorece la desregulación del mercado habitacional. La escasez de políticas habitacionales para inquilinos contrasta con la disponibilidad de viviendas que no se alquilan debido a conflictos y falta de control estatal respecto de precios, regulación y mediación contratos. La elaboración de una política pública para este mercado debería incluir una propuesta de impuestos a la vivienda desocupada, alquiler social e incentivos para la construcción de nuevas viviendas para atender la demanda de alquiler.

Abstract Renting property is a widespread practice in much of Argentina. This paper analyses the mechanisms of renting and initiatives to regulate the rental market in Rosario, the third city with the highest number of tenants in the country (2003-2023). Data from official and unofficial documents and press releases show that national legislation favors the deregulation of the housing market. The scarcity of housing policies for tenants contrasts with the availability of unrented housing due to conflicts and lack of state control over prices, regulation and mediation of contracts. The development of a public policy for this market should include a proposal for taxation of unoccupied housing, social renting and incentives for building new housing to meet rental demand.

Abstract Introduction: Passiflora tripartita var. mollissima (banana passionfruit) is one of the most promising exotic tropical fruits from the diversity of the Passifloraceae family in South America, because of its organoleptic properties and antioxidant activity. Objective: To evaluate the physiological and anatomical responses of banana passionfruit plants under water deficit to better understand the mechanisms that mitigate this stress and affect the production of crops subject to climate change and global warming. Methods: Three-month-old seedlings of banana passionfruit were subjected to a soil water deficit through an irrigation reduction at 70 % for 49 days under greenhouse conditions. Morphology (leaf area, height, and number of leaves) and physiological (stomatal conductance, Fv/Fm, total chlorophyll content) measurements were made through time, and after the irrigation treatments were measured biomass parameters and anatomical foliar traits. Results: The plants experienced a decrease in height, leaf area, number of leaves, leaf area index, and relative water content, that are common responses in plants subjected to reduced irrigation. Additionally, the plants exhibited certain mechanisms that can be attributed to water deficit tolerance such as higher root:shoot ratio, stomatal closing, an increase in stomatal density, a reduction in mesophyll tissue thickness, and a decrease in the number of vessels and its diameter as they enable the banana passionfruit to reduce water loss and decrease the probability of cavitation in xylem vessels. Conclusions: banana passionfruit plants could implement strategies against water scarcity, allowing them to survive and endure challenging environmental conditions.

Resumen Introducción: Passiflora tripartita var. mollissima (banana passionfruit - curuba) es una de las frutas tropicales exóticas de la diversidad de la familia Passifloraceae en Sudamérica, promisoria por sus propiedades organolépticas y actividad antioxidante. Objetivo: Evaluar las respuestas fisiológicas y anatómicas de la curuba bajo déficit hídrico con el fin de comprender mejor los mecanismos que mitigan este estrés y afectan la producción de sus cultivos, que están sujetos al cambio climático y al calentamiento global. Métodos: Plántulas de 3 meses de edad se sometieron a un déficit hídrico mediante una reducción del riego al 70 % durante 49 días en condiciones de invernadero. Se realizaron mediciones morfológicas (área foliar, altura y número de hojas) y fisiológicas (conductancia estomática, Fv/Fm, contenido de clorofilas) a lo largo del tiempo, y transcurridos los tratamientos de irrigación se midieron parámetros de biomasa, además de rasgos anatómicos foliares. Resultados: Las plantas experimentaron una disminución en la altura, área foliar, número de hojas, índice de área foliar y contenido relativo de agua, respuestas comunes en plantas sometidas a una irrigación reducida. Adicionalmente, las plantas exhibieron ciertos mecanismos que pueden atribuirse a la tolerancia al déficit hídrico tales como una mayor relación raíz:vástago, cierre de estomas, un aumento en la densidad estomática, una reducción en el grosor del tejido del mesófilo y una disminución en el número de vasos del xilema y su diámetro; pues le permiten a la curuba disminuir la pérdida de agua y reducir la probabilidad de cavitación en los vasos del xilema. Conclusiones: Las plantas de la curuba tienen la capacidad de implementar estrategias de mitigación frente al déficit hídrico, lo que les permite sobrevivir y soportar condiciones ambientales desafiantes.

Abstract The purpose of this article is to analyze the army of the Center’s organization, as well as its military action during the French intervention, and its subsequent destruction. I aim to demonstrate that its creation was intricately connected to the commitment and public reintegration efforts of its creator, former president Ignacio Comonfort. He faced significant challenges such as political opposition, resource scarcity, resistance from certain authorities, and public reluctance to collaborate. These challenges, coupled with the desertion, ill-advised decisions, political intrigues, inadequate equipment, and insufficient training ultimately led to its ineffectiveness. With a focus on political and military history, this article examines various primary sources such as Comonfort’s official and private correspondence, soldiers’ testimonies, newspaper articles, and military reports.

Resumen El objetivo de este artículo es analizar la organización del ejército del Centro, así como su participación militar en contra de la intervención francesa y su eventual destrucción. Me interesa demostrar que la formación de este ejército estuvo ligada al compromiso y a la rehabilitación pública de su creador, el expresidente Ignacio Comonfort, quien, no obstante, enfrentó serios problemas como oposición política, falta de dinero y resistencias a colaborar por parte de la población civil y de ciertas autoridades. Esto, sumado a las malas decisiones, a las intrigas, a la deserción y al descuido, ocasionó que el ejército del Centro se convirtiera en una fuerza ineficiente. Con un enfoque basado en la historia política y militar, este artículo examina diversas fuentes primarias, como la correspondencia oficial y privada de Comonfort, testimonios de los soldados, artículos de prensa e informes militares.

Abstract The Europeans of the Middle Ages have always valued bread within their food system, especially as meat, another highly valued food, became scarcer. But by tradition, more than a thousand years old, in Europe and the Mediterranean, bread was the food par excellence, the only one that the faithful asked God for in their prayers because it was the one whose lack meant hunger. Grain was grown everywhere, but this didn't stop times of scarcity and famine, both in the countryside and in the cities. While the latter had other means of responding to these crises and these phenomena have been better studied there, we barely know how rural people reacted to such adversities. The response of the rural world to the cereal crisis of 1438-1440 is analyzed through a book containing the accounts of the monastery of Alcobaça for the years 1437-1440. This is clearer for the monastery, since the peasants' reactions are more difficult to discern, as they are filtered through the eyes of the landlord. In 1439, the reduction of two-thirds in the abbey's cereal revenues was countered by the cultivation of target maize, a spring cereal that could replace wheat and barley. But the crisis had other effects, such as spiraling grain prices, rising flour extraction rates and a decline in the quality of daily bread, or the resort to substitute foods. From monks to peasants, everyone felt the consequences of this crisis, albeit on very different scales and in very dissimilar ways.

Resumo Os europeus da Idade Média sempre valorizaram o pão dentro do seu sistema alimentar, sobretudo à medida que a carne, outro alimento altamente valorizado, se ia tornando mais escassa. Mas, por tradição mais que milenar, na Europa e no Mediterrâneo, o pão era o alimento por excelência, o único que os fiéis pediam a Deus nas suas orações por ser aquele cuja falta era sinónimo da fome. O cereal cultivava-se por toda a parte, sem que isso impedisse as épocas de escassez e de carestia, tanto no campo, como nas cidades. Se estas últimas tinham outros meios para responder a essas crises e estes fenómenos foram aí mais estudados, mal se conhece o modo como os homens dos campos reagiam a tais adversidades. A partir de um livro com a contabilidade do mosteiro de Alcobaça dos anos de 1437-1440, analisa-se a resposta do mundo rural à crise cerealífera de 1438-1440. Mais clara no que respeita ao mosteiro, já que as reacções dos camponeses são mais difíceis de sondar, por estarem filtradas pelo olhar do senhorio. Em 1439, a redução em dois terços das receitas de cereal da abadia foi compensada pelo cultivo do milho-alvo, um cereal de primavera que podia substituir o trigo e a cevada. Mas a crise teve outros efeitos, como a espiral dos preços do cereal, o aumento das taxas de extração de farinha e a diminuição da qualidade do pão de cada dia, ou o recurso a alimentos de substituição. Dos monges aos camponeses, todos sentiram as consequências desta crise, embora em escalas e em modos muito diferentes.

SUMMARY: There exists a scarcity of neurocognitive research that has successfully used electrophysiology as an objective tool to assess different learning modalitiesthat are commonly used in anatomy. The objective of this study was to explore the trend in the expression of brain waves in medical students when using different didactic strategies in learning anatomy. An exploratory, observational, cross-sectional study was conducted on 22 first- semester medical students in anatomy. Using didactic strategies with different pedagogical tools such as biological models (human skulls and pig hearts) and/or digital application (Visible Body software), and different evaluation methods, students were grouped into three groups: "EOR1" students who learned using a skull and were evaluated with it; "EOV1" students who learned using a pig heart and were evaluated with the Visible Body software; and "EOV2" for students who learned through the Visible Body software and were evaluated with it. During the evaluation, each student was monitored in real-time using an electroencephalogram and the Emotiv EPOC brain-computer interface system to record the electro-physiological activity of beta (B), theta (T), and gamma (G) waves. The data obtained (the trend of the electrical activity of each wave and its relationship with students' performance in each didactic strategy) were analyzed using Pearson's correlation coefficient. Groups EOR1 and EOV1 had satisfactory results in their evaluations and showed a predominance of B waves (x=67.33) and T waves (x=57.67). Additionally, a strongly positive correlation (r=0.82) was found between the presence of B waves and the duration of T waves. Students who used three-dimensional biological models as a pedagogical tool showed a predominance of B and T waves, which are associated with sensorimotor and exploratory learning necessary for studying anatomy.

RESUMEN: Son escasos los estudios de neurociencia cognitiva que permitan comprender, de manera objetiva, las manifestaciones electrofisiológicas de los estudiantes de medicina expuestos a diferentes herramientas pedagógicas utilizadas en el área de anatomía. El objetivo de este trabajo fue explorar la tendencia en la expresión de las ondas cerebrales de estudiantes de medicina, al utilizar diferentes estrategias didácticas en el aprendizaje de la anatomía. Se realizó un estudio exploratorio, observacional, de corte transversal en 22 estudiantes de medicina de primer semestre en anatomía. Utilizando estrategias didácticas con diferentes herramientas pedagógicas; como modelos biológicos (cráneos humanos y corazones porcinos) y/o aplicación digital (software Visible Body (SVB)), y diferente método de evaluación, se agruparon los estudiantes en tres grupos: “EOR1” estudiantes que aprendieron usando un cráneo y se evaluaron con este, “EOV1” estudiantes que aprendieron usando un corazón porcino y fueron evaluados con el SVB, y “EOV2” para los estudiantes que aprendieron a través del SVB y fueron evaluados con este. Durante la evaluación, cada estudiante fue monitorizado en tiempo real, utilizando un electroencefalograma y el sistema interfaz cerebro - computadora Emotiv EPOC para registrar la actividad electrofisiológica de las ondas beta (B), theta (T) y gamma (G). Los datos obtenidos (tendencia de la actividad eléctrica de cada onda y su relación con el desempeño de los estudiantes en cada estrategia didáctica) fueron analizados usando el índice de correlación de Pearson. Los grupos EOR1 y EOV1, tuvieron resultados satisfactorios en sus evaluaciones y presentaron predominio de ondas B (X=67,33) y T (X=57,67), además, se evidenció una correlación fuertemente positiva (r=0,82) entre la presencia de B y el tiempo de permanencia de T. Los estudiantes que utilizaron modelos biológicos tridimensionales como herramienta pedagógica presentaron predominio de las ondas B y T, asociadas con aprendizajes sensoriomotores y de tipo exploratorio necesarios para el estudio en anatomía.

Abstract Objective This study aimed to review literature from the past five years, focusing on the use of educational videos as a guidance tool for parents and guardians of children with lip and palate clefts. Source of data Conducted between April and July 2022, this integrative literature review was framed around the question: 'What is the evidence regarding the use of videos in health education for parents/guardians of children with cleft lip and palate? PICO strategy was used to develop the research. A literature search was undertaken across PubMed, Web of Science, Scopus, and the Virtual Health Library databases. Of the eight articles included in this review, four were sourced from the PubMed database, with three published in 2021. Summary of the findings The findings indicated that YouTube videos were moderately satisfactory and met the needs of parents or legal guardians to a partial extent. The majority of the videos analyzed in this review were characterized by a moderate level of informational content. One study particularly underscored that the content of these videos only partially satisfies the requirements of the parents or legal guardians of the children. Conclusions Nevertheless, such videos are considered viable alternatives for health education, offering numerous benefits yet facing challenges, primarily due to the scarcity of information on orofacial malformations. years clefts 2022 question What parentsguardians research Science Scopus databases database 2021 extent Nevertheless challenges malformations 202 20 2

ABSTRACT This paper proposes a composite indicator to identify levels of water security at the household-community interface. It analyses the hydro-social processes that give rise to water scarcity situations experienced by the rural population supplied by community organizations in rural Chile. The indicator is based on a case study of ten community organizations selected to represent the heterogeneity existing in the country, where semi-structured interviews with their leaders and field observations were applied. Two main findings emerge from the study: 1) there is no correlation between the size of organizations and the levels of observed water security; 2) cases with greater difficulty accessing sufficient resources are not the ones facing greater water insecurity, as organizations compensate for this difficulty with other components.

RESUMEN El presente artículo propone un indicador compuesto que permite identificar niveles de seguridad hídrica en la interfaz doméstica-comunitaria. Para ello analiza los procesos hidrosociales que dan origen a situaciones de escasez hídrica vividas por la población rural abastecida mediante organizaciones comunitarias en Chile rural. El indicador se basa en el estudio de caso de diez organizaciones comunitarias seleccionadas para representar la heterogeneidad existente en el país, a cuyos dirigentes se les aplicó entrevistas semiestructuradas en las cuales se realizaron, además, observaciones de campo. Del estudio se desprenden dos principales hallazgos: 1) No existe una correlación entre el tamaño de las organizaciones y los niveles de seguridad hídrica observados; 2) Los casos con mayores dificultades para acceder a recursos en cantidad suficiente no son los que enfrentan una inseguridad hídrica mayor, puesto que las organizaciones compensan esta dificultad con otros componentes.

Abstract Introduction: Nursing, as a science and discipline, faces the challenge of missed care and omissions that affect the safety and quality of care. Objective: to analyze the scientific evidence related to missed care in nursing, highlighting its impact on safety and quality of care. Methodology: A systematic review of articles was conducted between 2018 and 2023, with a descriptive design, following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) flowchart. The study was conducted between September and December 2023, collecting articles related to lost care in nursing from open-access indexed journals in the following repositories: Scielo, Redalyc, PubMed, Wos, Scopus, and CINAHL. Selection and exclusion criteria were applied, and original qualitative and quantitative articles were chosen with a maximum validity of 6 years. The review focused on literature in English, Spanish, and Portuguese. Ethical standards were rigorously respected, guaranteeing confidentiality and treating sensitive information ethically. Results: 7 articles were included, which revealed disparities in lost care between public and private hospitals, highlighting the gap in resources, in addition to emphasizing the relationship between lost care and professional burnout, omissions in primary nursing care such as handwashing, along with the importance of planning care through the nursing process, to ensure compliance and recording of this care. Conclusion s: Strategies such as humanizing care, developing plans for resource scarcity, and maintaining an adequate nurse-patient relationship are essential to address the issue of lost care.
