RESUMO O objetivo da presente pesquisa foi investigar as realidades e desafios da intersetorialidade nas cidades/região que possuem estruturação dos grupos de trabalho intersetorial municipal (GTI-M) no Programa Saúde na Escola (PSE) no período 2017-2021. Tratou-se de um pesquisa com levantamento documental e revisão integrativa para seleção de artigos nos idiomas português e inglês. Sete registros de documentos oficiais foram encontrados que norteiam as diretrizes para ações de adesão, pactuação, planejamento, execução e monitoramento do PSE e nove artigos de diferentes regiões do País onde foi observado as formas de relações de trabalho frente a intersetorialidade: sudeste (cinco); nordeste (dois); regiões sul (1) e região norte (1). A percepção sobre o trabalho intersetorial, ainda é carente de entendimento, envolvimento e efetivação dos GTI-M, o que dificulta a implementação de mecanismos facilitadores das ações do PSE. Além disso, existe uma falta de articulação municipal, a partir do decreto oficial para GTI-M, o que acaba promovendo ações fragmentadas, desgaste das equipes, diminuindo impactos positivos que o PSE pode promover na saúde coletiva. O estudo pode servir de base para reformulação de estratégias e de mecanismos de controle do governo federal para execução e liberação de verbas para o PSE.

ABSTRACT Objective: Investigate the realities and challenges of Intersectoriality in cities/regions that have structured municipal intersectoral working groups (GTI-M) in the Health at School Program (PSE) in the period 2017-2021. Method: Research with documental survey and integrative review to select articles in Ingles and Portuguese. Results: Records of official documents that guide the guidelines for actions of adherence, agreement, planning, execution and monitoring of the PSE and nine articles from different regions of the country where the forms of work in front of the intersectoriality were observed: southeast (five); northeast (two); south regions (1) and north region (1). Conclusion: The perception of intersectoral work still lacks understanding, involvement and effectiveness of the GTI-M, which makes it difficult to implement mechanisms that facilitate PSE actions. In addition, there is a lack of municipal articulation, based on the official decree for GTI-M, which ends up promoting fragmented actions, team wear, reducing the positive impacts that the PSE can promote in collective health. The study can serve as a basis for reformulating strategies and control mechanisms of the federal government to execution and release of funds for PSE.

ABSTRACT Objective To describe and compare the clinical characteristics and outcomes of patients admitted to intensive care units during the first and second waves of the COVID-19 pandemic. Methods In this retrospective single-center cohort study, data were retrieved from the Epimed Monitor System; all adult patients admitted to the intensive care unit between March 4, 2020, and October 1, 2021, were included in the study. We compared the clinical characteristics and outcomes of patients admitted to the intensive care unit of a quaternary private hospital in São Paulo, Brazil, during the first (May 1, 2020, to August 31, 2020) and second (March 1, 2021, to June 30, 2021) waves of the COVID-19 pandemic. Results In total, 1,427 patients with COVID-19 were admitted to the intensive care unit during the first (421 patients) and second (1,006 patients) waves. Compared with the first wave group [median (IQR)], the second wave group was younger [57 (46-70) versus 67 (52-80) years; p<0.001], had a lower SAPS 3 Score [45 (42-52) versus 49 (43-57); p<0.001], lower SOFA Score on intensive care unit admission [3 (1-6) versus 4 (2-6); p=0.018], lower Charlson Comorbidity Index [0 (0-1) versus 1 (0-2); p<0.001], and were less frequently frail (10.4% versus 18.1%; p<0.001). The second wave group used more noninvasive ventilation (81.3% versus 53.4%; p<0.001) and high-flow nasal cannula (63.2% versus 23.0%; p<0.001) during their intensive care unit stay. The intensive care unit (11.3% versus 10.5%; p=0.696) and in-hospital mortality (12.3% versus 12.1%; p=0.998) rates did not differ between both waves. Conclusion In the first and second waves, patients with severe COVID-19 exhibited similar mortality rates and need for invasive organ support, despite the second wave group being younger and less severely ill at the time of intensive care unit admission.

BACKGROUND Leishmania RNA virus 1 (LRV1) is commonly found in South American Leishmania parasites belonging to the subgenus Viannia, whereas Leishmania RNA virus 2 (LRV2) was previously thought to be restricted to the Old-World pathogens of the subgenus Leishmania. OBJECTIVES In this study, we investigated the presence of LRV2 in strains of Leishmania (L.) infantum, the causative agent of visceral leishmaniasis (VL), originating from different hosts, clinical forms, and geographical regions. METHODS A total of seventy-one isolates were screened for LRV2 using semi-nested reverse transcription-polymerase chain reaction (RT-PCR) targeting the RNA-dependent RNA polymerase (RdRp) gene. FINDINGS We detected LRV2 in two L. infantum isolates (CUR268 and HP-EMO) from canine and human cases, respectively. MAIN CONCLUSIONS To the best of our knowledge, this is the first detection of LRV2 in the New World.

Resumen Se presentan los resultados de las excavaciones y análisis de artefactos, ecofactos y arte rupestre del sitio Infieles-1, Puna de Atacama, Chile. Este sitio se emplaza adyacente a un paredón de ignimbrita con diversas manifestaciones rupestres. El análisis de estas pinturas y grabado, junto a la excavación realizada permitió identificar tres ocupaciones alfareras. La primera se relaciona con portadores de cerámica Condorhuasi-Río Diablo del Formativo del Noroeste de Argentina, unida a manifestaciones que poseen referentes en la modalidad estilística Punta del Pueblo de Antofagasta de la Sierra (500-1000 d.C.), coherente con el fechado radiocarbónico (AMS) obtenido en Infieles-1. A continuación, y hacia fines de este lapso, se identificaron posibles motivos Ánimas y, por último, un tercer momento asociado probablemente al Período Intermedio Tardío/Período Tardío, a partir de manifestaciones culturales del norte y centro de la región de Atacama. Asimismo, se describe sucintamente el arte rupestre histórico del sitio, analizando sus definiciones e implicancias culturales. En síntesis, se caracterizan y discuten, desde una perspectiva internodal y de tráfico regional e interregional, las ocupaciones temporales y diacrónicas del sitio por parte de grupos locales, responsables del arte rupestre en Infieles durante la época alfarera, y que manifiestan acentuadas interrelaciones culturales con espacios trasandinos.

Abstract This article presents the results of excavations and analyses of artifacts, ecofacts and rock art from the Infieles-1 site at Puna de Atacama, Chile. This site is located adjacent to an ignimbrite wall with several rock paintings. The analysis of these paintings and engravings, together with the excavation carried out, made it possible to identify three pottery occupations. The first is related to Condorhuasi-Río Diablo ceramic carriers from the Formative period from northwestern Argentina, together with manifestations that have references in the Punta del Pueblo de Antofagasta de la Sierra stylistic modality (500-1000 AD), consistent with the radiocarbon dating (AMS) obtained in Infieles-1. Towards the end of this period, possible Ánimas motifs were identified and, finally, there was a third moment probably associated with the Late Intermediate Period/Late Period based on cultural manifestations from the northern and central Atacama region. A brief description of the historical rock art found at the site is also provided with an analysis of its definitions and cultural implications. In summary, the temporal and diachronic occupations of the site by local groups responsible for the rock art at Infieles during the pottery period are described and discussed as manifesting accentuated cultural interrelations with trans-Andean spaces from an internodal perspective and from a regional and interregional traffic perspective.

Abstract Objectives The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID-|19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. Conclusion The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.

Resumen Objetivo: Identificar en qué medida la salud mental y bienestar subjetivo son predichas por el endeudamiento por motivos de estudio en estudiantes universitarios de la ciudad de Temuco, Chile. Método: Una muestra no probabilística de 151 estudiantes universitarios de quinto año o superior de su respectiva carrera universitaria respondió a medidas de salud mental (DASS-21), de bienestar subjetivo (satisfacción con la vida y felicidad subjetiva), y del nivel de endeudamiento asumido para financiar sus estudios universitarios. Los análisis incluyeron regresiones lineales múltiples jerárquicas donde se incluyeron como variables independientes la variable género en un primer paso y el endeudamiento por créditos universitarios en el segundo paso. En cada regresión se incluyó un factor de salud mental y de bienestar subjetivo como variable dependiente. Resultados: Resultados indican que el endeudamiento por motivos de estudio predice significativa- mente satisfacción con la vida (F(2, 148) = 5,95, p = 0,003, R2Adjusted = 0,06; β =-0,16, p = 0,049), pero no predice felicidad subjetiva (p = n.s.) (factores de bienestar subjetivo), sintomatología depresiva (p = n.s.), ansiosa (p = n.s.), ni estrés (p = n.s.) (factores de salud mental). Conclusión: Resultados del estudio sugieren que los estudiantes universitarios pudieran percibir el endeudamiento estudiantil como una inversión hacia el futuro lo que pudiera operar como un factor protector de su salud mental y bienestar subjetivo.

Abstract Objective: To evaluate if debt due to university loans predicts mental health and subjective well-being in university students of Temuco, Chile. Method: A non-probabilistic sample of 151 last-year university students completed measures of mental health (DASS-21), of subjective well-being (satisfaction with life, and subjective happiness), and debt levels due to student loans. Analyses included hierarchical multiple linear regressions where gender was entered in a first step and debt due to university loans on a second step as independent variables. Each regression considered a factor of mental health or a factor of subjective well-being as the dependent variable. Results: Results show that debt due to university loans predict predicts satisfaction with life (F(2, 148) = 5,95, p = 0,003, R2Adjusted = 0,06; β =-0,16, p = 0,049), but not subjective happiness (p = n.s.) (factors of subjective well-being), nor symptoms of depression (p = n.s.), anxiety (p = n.s.), or stress (p = n.s.) (factors of mental health). Conclusion: Results of this study suggest that university students may perceive student debt as an investment which may act as a protective factor of their mental health and subjective well-being.

Resumen La gonartrosis es una enfermedad de alta prevalencia en adultos mayores. El objetivo de esta investigación fue identificar los cambios en la fuerza muscular del cuádriceps y su efecto en la funcionalidad de los pacientes operados de artroplastia total de rodilla (ATR) sometidos a kinesiterapia en el Hospital El Carmen de Maipú (HEC). A todos los operados de ATR se les midió, pre y post intervención, fuerza isométrica máxima (FIM), Time Up and Go, test de pararse y sentarse, apoyo unipodal y la escala WOMAC. La FIM de la rodilla operada y la no operada, es mayor en flexión y extensión al comparar ambos géneros (p < 0.0001; p < 0.0001, respectivamente). En el up and go y la prueba pararse y sentarse el rendimiento fue significativamente superior para el género masculino en relación al femenino (p = 0.001; p = 0.007, respectivamente). En el WO MAC, existieron diferencias significativas pre y post intervención en hombres y mujeres (p < 0.0001; p < 0.0001, respectivamente). Los pacientes con un índice de masa corporal (IMC) > 30 kg/m2 tienen 3 veces menos posi bilidades [OR = -3.498; IC (0.062-1.067)] de permanecer en tratamiento en un plazo menor a 50 días. Por otra parte, las lesiones en la rodilla no dominante (izquierda) tiene 4 veces más posibilidades de tratamiento inferior a 50 días [(OR = 2.71; IC (1.000-16.252)]. Existió un aumento de la FIM de la rodilla tratada post intervención, en ambos géneros. La funcionalidad aumentó en hombres y mujeres, posterior a la intervención.

Abstract Gonarthrosis is a highly prevalent disease in older adults. The objective of this re search was to identify changes in quadriceps muscle strength and their impact on the functionality of total knee replacement (TKA) operated patients undergoing kinesitherapy at Hospital El Carmen de Maipú (HEC). All TKA operated patients were measured, pre and post intervention, maximum isometric strength (MIF), Time Up and Go, Standing and sitting test, Unipodal support and the WOMAC scale. The operated and contralateral MIF is higher in flexion and extension when comparing both genders (p < 0.0001; p < 0.0001, respectively). In the up and go and the standing and sitting test, performance was significantly higher for males than for females (p = 0.001; p = 0.007, respectively). In the WOMAC, there were significant differences before and after the intervention in men and women (p < 0.0001; p < 0.0001, respectively). Patients with a body mass index (BMI) > 30 kg/m2 are 3 times less likely [OR = -3.498; CI (0.062-1.067)] to receive treatment in a period of less than 50 days. On the other hand, injuries to the non-dominant (left) knee have a 4 times greater chance of stay in treatment in less than 50 days [(OR = 2.71; CI (1.000-16.252)]. There was an increase in MIF of the knee treated post-intervention, in both genders. Functionality increased in men and women, after the intervention.

Abstract The FinTech industry includes crowdfunding companies, which consist of collaborative financing platforms. The potential use of crowdfunding among Chilean undergraduate students is empirically analyzed. An ordered probit model is used to test the determinants of the probability that a student will use a crowdfunding platform in the future. Also, a qualitative analysis containing arguments by which students would or would not use crowdfunding in the future is presented. The results indicate that trust in financial institutions and prior crowdfunding knowledge have a positive and significant effect on the probability of using these platforms. This paper constitutes one of the first to explore the growing crowdfunding market in Chile from the demand perspective.

Background: Colorectal cancer has a high global mortality and tumor markers have emerged as diagnostic, management and prognostic indicators. New markers are being studied. Objective: To verify if there is a correlation between the immunohistochemical expression of ALCAM and ALDH1 proteins in colorectal adenocarcinoma tissue with epidemiological and clinicopathological characteristics, in particular their impact on disease progression and death. Method: Observational, single-center, analytical, retrospective study, through the investigation of patients undergoing surgical resection for colorectal cancer. 122 patients were evaluated. Regarding progression, it was shown that in individuals with positive ALCAM (n=40), 14/40 (35%) had progression, and for positive ALDH (n=54), 22/54 (40.7%). For death, the analysis of ALCAM positive (n=40), 24/40 (60%) died, and ALDH1 positive (n=54), 33/54 (61.1%). Conclusion: The immunohistochemical expression of ALCAM and ALDH1 markers was not associated with disease progression and death; it was also not possible to observe a correspondence relationship with the evaluated markers.

Racional: O câncer colorretal apresenta alta mortalidade global e marcadores tumorais têm surgido como sinalizadores de diagnóstico, manejo e prognóstico. Novos marcadores estão sendo estudados. Objetivo: Verificar se há correlação da expressão por imunoistoquímica das proteínas ALCAM e ALDH1 em tecido com adenocarcinoma colorretal com as características epidemiológicas e clinicopatológicas, em particular o seu impacto na progressão de doença e no óbito. Método: Estudo observacional, unicêntrico, analítico, retrospectivo, através da investigação de pacientes submetidos à ressecção cirúrgica por câncer colorretal. Foram avaliados 122 pacientes. Em relação a progressão, mostrou-se que nos indivíduos com ALCAM positiva (n=40), 14/40 (35%) tiveram progressão, e para ALDH positiva (n=54), 22/54 (40,7%). Para óbito, a análise da ALCAM positiva (n=40), 24/40 (60%) morreram, e ALDH1 positivo (n=54), 33/54 (61,1%). Conclusão: A expressão imunoistoquímica dos marcadores ALCAM e ALDH1 não apresentou associação com a progressão de doença e óbito; também não foi possível observar relação de correspondência com os marcadores avaliados.

Resumen El objetivo fue evaluar la productividad, el precio de venta de leche, el tamaño y las percepciones de sus propietarios sobre su entorno, calidad y permanencia en explotaciones de producción de leche del estado de Aguascalientes. Se evaluaron 40 unidades de producción de leche, con condiciones semejantes de antigüedad (30 años), manejo zootécnico, disponibilidad de insumos y clientes. A través de un MANOVA se compararon las características productivas de las explotaciones con relación al factor del tamaño del hato. Se formuló un modelo estructural para evaluar el efecto de los factores del entorno sobre la calidad de la leche y la intención de los granjeros en dar continuidad a las unidades de producción en la actividad lechera. Se encontró influencia positiva en la escala productiva de las explotaciones lecheras, la obtención de mayor productividad diaria por vaca, mejor percepción de calidad y el precio de venta de la leche. En el modelo, los factores del entorno se asociaron significativamente con la valoración de la calidad de la leche por los productores y su permanencia de la actividad lechera (14.2 y 22.7 %, respectivamente). Lo anterior confirma que la percepción de factores del entorno pudiera ser considerado como variable crucial para incrementar la calidad de la leche, la productividad y para el encuentro entre los intereses de los productores y de la agroindustria, así como para favorecer el desempeño e integración de los diferentes eslabones de la cadena productiva lechera e impulsar la competitividad global del sector agroalimentario mexicano.

Abstract The objective was to evaluate the productivity, the sale price of milk, the size and the perceptions of their owners about their environment, quality and permanence in milk production farms in the state of Aguascalientes. Forty milk production units, with similar conditions of age (30 years), zootechnical management, availability of inputs and customers, were evaluated. The productive characteristics of the farms in relation to the herd size factor were compared through a MANOVA. A structural model was formulated to evaluate the effect of environmental factors on milk quality and farmers’ intention to continue production units in the dairy activity. A positive influence was found on the productive scale of dairy farms, the obtaining of higher daily productivity per cow, better perception of quality and the sale price of milk. In the model, environmental factors were significantly associated with the assessment of milk quality by producers and their permanence in the dairy activity (14.2 and 22.7 %, respectively). This confirms that the perception of environmental factors could be considered as a crucial variable to increase milk quality, productivity and for the meeting between the interests of producers and the agribusiness, as well as to favor the performance and integration of the different links in the dairy production chain and boost the global competitiveness of the Mexican agri-food sector.

Abstract Introduction/objective: greenhouse gases (GHG) emissions of natural origin have increased due to anthropogenic actions and threaten the planet with environmental imbalance. Reservoirs for storing water, which is later used to drive the turbines of hydroelectric power plants, accumulate sediments, generating GHG. This paper analyzes the methods used to estimate GHG emissions in reservoirs, classifying scientific publications found in the ScienceDirect and Google Scholar search engines. Methodology: the analytical method uses a Boolean expression to collect information in the indicated search engines and extract the relevant literature considering factors such as water temperature, geographic location, reservoir type and surface area, gas type and technology, which attributes a relevance value to each characteristic to elaborate a matrix of results. Results: the results show that more than 50 % are based on GHG estimates and the rest on direct measurements in the reservoirs. In addition, the contribution of artificial intelligence as an estimation technique is less than 6 %. Conclusions: finally, the world regions where studies are conducted are proportionally distributed and the analysis of scientific literature indicates versatility in GHG estimation methods in hydropower reservoirs.

Resumen Introducción/objetivo: las emisiones de gases de efecto invernadero (GEI) de origen natural han aumentado por las acciones antropogénicas, y amenazan al planeta con un desequilibrio ambiental. Los embalses para almacenar agua, que después se utiliza para mover las turbinas de centrales hidroeléctricas, acumulan sedimentos generando GEI. En este trabajo se analizan los métodos empleados para estimar las emisiones de GEI en embalses, clasificando las publicaciones científicas encontradas en los motores de búsqueda de ScienceDirect y Google Scholar. Metodología: el método analítico utiliza una expresión booleana para recopilar información en los motores de búsqueda indicados y extraer la bibliografía relevante, considerando factores como la temperatura del agua, la ubicación geográfica, el tipo y la superficie del embalse, el tipo de gas y la tecnología, lo que atribuye un valor de pertinencia a cada característica para elaborar una matriz de resultados. Resultados: los resultados muestran que más del 50 % se basan en estimaciones de GEI y el resto en mediciones directas en los embalses. Además, la contribución de la inteligencia artificial como técnica de estimación es menor al 6 %. Conclusiones: finalmente, las regiones mundiales donde se realizan los estudios están distribuidas proporcionalmente y el análisis de literatura científica indica versatilidad en los métodos de estimación de GEI en embalses hidroeléctricos.

ABSTRACT This research was conducted based on the importance of axiology and natural law in the construction of an ethical justification of law. The hermeneutic philosophical method was used, given that it proposes a critical and anti-dogmatic use of reason, allowing to ponder how the ethical-valuative dimension has been developing in current debates and, to that extent, to evaluate the possible orientations for the ethical justification of law. In this sense, the aim of this paper was to carry out a critical analysis of the higher ethical principles that act as value criteria for the ethical justification of law based on the notions of axiology and natural law.

RESUMEN Esta investigación se realizó en torno a la importancia de la axiología y del derecho natural en la construcción de una justificación ética del derecho. Se abordaron varias teorías para pensar dicho fenómeno, se utilizó el método filosófico hermenéutico, ya que propone un uso crítico y antidogmático de la razón, permitiendo ponderar cómo se ha venido desarrollando la dimensión ética-valorativa en los debates actuales y, en esa medida, evaluar las posibles orientaciones para la justificación ética del derecho. En este sentido, el objetivo de este trabajo fue realizar un análisis crítico respecto de los principios éticos superiores que actúan como criterios valorativos para la justificación ética del derecho a partir de las nociones de axiología y derecho natural.

Resumen Objetivo: Evaluar la incidencia, los posibles factores de riesgo y el manejo de la lesión rectal durante la prostatectomía radical. Diseño, metodología o aproximación: La lesión rectal es una complicación poco frecuente pero potencialmente grave de la prostatectomía radical (PR). La evidencia actual es limitada debido a que la mayoría de los estudios se basan en series relativamente pequeñas. Se revisaron de manera retrospectiva un total de 147 prostatectomías radicales laparoscópicas de enero de 2017 a abril de 2021. Se encontraron 4 pacientes con lesión rectal durante el procedimiento. Resultados: Del total de pacientes con lesión rectal durante el procedimiento existía extensión extraprostática en la RM precirugía en el 50% de los pacientes. Ninguno tenía antecedentes de RT previa. Se realizó cierre primario mediante dos capas de sutura en todos los casos. En un caso (25%) se realizó colostomía intraoperatoria. Uno de los cuatro pacientes (25%) desarrolló una fístula rectal con peritonitis secundaria por la que tuvo que ser reintervenido. El tiempo en dieta absoluta varió desde 0 días a 2 días y el tiempo de antibioterapia difirió en todos los pacientes. Discusión: La lesión rectal ocurre en el 0.1-1.8% de pacientes sometidos a prostatectomía radical e incrementa de manera significativa la morbilidad del procedimiento. La mayoría de las lesiones rectales se producen durante las maniobras de disección del plano entre las vesículas seminales, la próstata y el recto. Para su detección se recomienda realizar un tacto rectal y insuflar aire por el recto intraoperatoriamente. Los factores de riesgo para su aparición son la RT previa, un tumor avanzado y una baja experiencia del cirujano en el procedimiento. La interposición de tejido en los defectos rectales sigue generando controversia. A pesar del cierre primario existe riesgo de fístula rectal, sobre todo en los casos de defectos mayores de 2 cm, RT previa o infiltración tumoral del recto. Conclusiones: La lesión rectal es una complicación rara pero grave que puede complicar el postoperatorio de la prostatectomía radical.

Abstract Objective: To evaluate the incidence, possible risk factors and management of rectal injury during radical prostatectomy. Design, methodology or approach: Rectal injury is a rare but potentially serious complication of radical prostatectomy (RP). Current evidence is limited as most studies are based on relatively small series. A total of 147 laparoscopic radical prostatectomies were retrospectively reviewed from January 2017 to April 2021. Four patients with rectal injury were found during the procedure. Results: Of the total number of patients with rectal injury during the procedure, there was extraprostatic extension in the pre-surgery MRI in 50% of the patients. None had a history of previous RT. Primary closure was performed using two layers of suture in all cases. In one case (25%) an intraoperative colostomy was performed. One of the four patients (25%) developed a rectal fistula with secondary peritonitis for which he had to undergo another operation. The time on absolute diet varied from 0 days to 2 days and the time of antibiotic therapy differed in all patients. Discussion: Rectal injury occurs in 0.1-1.8% of patients undergoing radical prostatectomy and significantly increases the morbidity of the procedure. Most rectal injuries occur during plane dissection maneuvers between the seminal vesicles, prostate, and rectum. To detect it, it is recommended to perform a digital rectal examination and insufflate air through the rectum intraoperatively. The risk factors for its appearance are previous RT, an advanced tumor and a low experience of the surgeon in the procedure. The interposition of tissue in rectal defects continues to generate controversy. Despite primary closure, there is a risk of rectal fistula, especially in cases of defects larger than 2 cm, previous RT, or tumor infiltration of the rectum. Conclusions: Rectal injury is a rare but serious complication that can complicate the postoperative period of radical prostatectomy.

RESUMO Objetivo: Determinar o grau de sofrimento psicológico e medo da COVID-19 experimentado por estudantes de enfermagem que estavam prestes a iniciar seus estágios clínicos. Método: Um estudo transversal foi realizado em 100 estudantes de enfermagem do segundo e terceiro anos da Universidade de Zaragoza (Espanha). As medidas incluíram a Escala de Medo da COVID-19 e as escalas de Depressão, Ansiedade e Estresse. Resultados: Regularmente, os estudantes de enfermagem não se consideravam vulneráveis à COVID-19. No entanto, observou-se associação significativa entre o nível de sofrimento psicológico dos estudantes de enfermagem e a convivência com familiares ou pessoas percebidas como vulneráveis à infecção (p = 0,035). Os resultados da Escala de Depressão, Ansiedade e Estresse revelaram um baixo nível de sofrimento psicológico em geral; a Escala de Medo da COVID-19 indicou um medo moderado (2,94). Conclusão: Estudantes de enfermagem que moravam com seus familiares experimentaram níveis mais altos de estresse devido ao risco percebido de transmissão, mas tinham menos medo de perda de trabalho e renda. A ansiedade em nossa amostra foi associada principalmente ao desconhecimento de seu próximo local de estágio.

ABSTRACT Objective: To determine the degree of psychological distress and fear of COVID-19 experienced by undergraduate student nurses who were about to begin their clinical placements. Method: A cross-sectional study was carried out with 100 second- and third-year undergraduate student nurses of the University of Zaragoza (Spain). Measures included the Fear of COVID-19 Scale and the Depression Anxiety Stress Scales. Results: Regularly, student nurses did not think of themselves as vulnerable to COVID-19. However, a significant association was observed between the student nurses’ level of psychological distress and cohabiting with relatives or people who were considered vulnerable to the infection (p = 0.035). The Depression Anxiety Stress Scale results revealed a low level of psychological distress in general; the Fear of COVID-19 Scale indicated moderate fear (2.94). Conclusion: Student nurses who lived with their relatives experienced higher levels of stress due to the perceived risk of transmission, but were less fearful of loss of work and income. Anxiety in our sample was associated principally with not knowing their upcoming placement location.

RESUMEN Objetivo: Determinar el grado de angustia psicológica y miedo al COVID-19 que experimentan los estudiantes de pregrado de enfermería que estaban a punto de empezar sus prácticas clínicas. Método: Se realizó un estudio transversal en 100 estudiantes de enfermería de segundo y tercer año de la Universidad de Zaragoza (España). Las medidas incluyeron la Escala de Miedo a la COVID-19 y la Escala de Depresión, Ansiedad y Estrés. Resultados: Normalmente, los estudiantes de enfermería no se consideraban vulnerables a la COVID-19. Sin embargo, se observó una asociación significativa entre el nivel de distrés psicológico de los estudiantes de enfermería y la convivencia con familiares o personas percibidas como vulnerables a la infección (p = 0,035). Los resultados del Escala de Depresión, Ansiedad y Estrés revelaron un bajo nivel de distrés psicológico en general; la Escala de Miedo a la COVID-19 indicó un miedo moderado (2,94). Conclusión: Los estudiantes de enfermería que vivían con sus familiares experimentaron mayores niveles de estrés debido al riesgo percibido de transmisión, pero tenían menos miedo a la pérdida de trabajo e ingresos. La ansiedad en nuestra muestra se asoció principalmente con el desconocimiento de su próxima ubicación de colocación.
