The Myth of the Ages on Chilean Lands

Los poetas que cantaron la Guerra de Arauco en Chile, en el siglo XVI, recurrieron a la tradición clásica para representar este conflicto, evocando así diversos tópicos de la literatura antigua. Uno de ellos fue el mito de las edades, motivo que les sirvió para contrastar el mundo de la guerra en que vivían, y los ideales que sentían perdidos y que añoraban para su propia época. Los poemas La Araucana, Purén Indómito y Las Guerras de Chile, se sirvieron de este tópico para comprender el momento que vivían, otorgando a la tradición literaria un valor histórico, al cargar de sentido a sus testimonios y vivencias.The poets who wrote on Arauco's War in Chile, in the 16th century, resorted to the classic tradition to represent this conflict, evoking topics of the ancient literature as the myth of the ages. This motive served them to contrast the world of the war in which they were, and the ideal ones which were feeling lost and which were yearning for their own epoch. The poems La Araucana, Purén Indómito and Las Guerras de Chile, rescued this topic to understand their own moment, granting to the literary tradition a historical value, on granting sense to their testimonies and experiences

Accidental catheter removal in critically ill patients: a prospective and observational study

INTRODUCTION: The importance of accidental catheter removal (ACR) lies in the complications caused by the removal itself and by catheter reinsertion. To the best of our knowledge, no studies have analyzed accidental removal of various types of catheters in the intensive care unit (ICU). The objective of the present study was to analyze the incidence of ACR for all types of catheters in the ICU. METHODS: This was a prospective and observational study, conducted in a 24-bed medical/surgical ICU in a university hospital. We included all consecutive patients admitted to the ICU over 18 months (1 May 2000 to 31 October 2001). The incidences of ACR for all types of catheters (both per 100 catheters and per 100 catheter-days) were determined. RESULTS: A total of 988 patients were included. There were no significant differences in ACR incidence between the four central venous access sites (peripheral, jugular, subclavian and femoral) or between the four arterial access sites (radial, femoral, pedal and humeral). However, the incidence of ACR was higher for arterial than for central venous catheters (1.12/100 catheter-days versus 2.02/100 catheter-days; P < 0.001). The incidences of ACR/100 nonvascular catheter-days were as follows: endotracheal tube 0.79; nasogastric tube 4.48; urinary catheter 0.32; thoracic drain 0.56; abdominal drain 0.67; and intraventricular brain drain 0.66. CONCLUSION: We found ACR incidences for central venous catheter, arterial catheter, endotracheal tube, nasogastric tube and urinary catheter that are similar to those reported in previous studies. We could not find studies that analyzed the ACR for thoracic, abdominal, intraventricular brain and cardiac surgical drains, but we believe that our rates are acceptable. To minimize ACR, it is necessary to monitor its incidence carefully and to implement preventive measures. In our view, according to establish quality standards, findings should be reported as ACR incidence per 100 catheters and per 100 catheter-days, for all types of catheters

Severe manifestations of SARS-CoV-2 in children and adolescents: from COVID-19 pneumonia to multisystem inflammatory syndrome: a multicentre study in pediatric intensive care units in Spain

Background Multisystem inflammatory syndrome temporally associated with COVID-19 (MIS-C) has been described as a novel and often severe presentation of SARS-CoV-2 infection in children. We aimed to describe the characteristics of children admitted to Pediatric Intensive Care Units (PICUs) presenting with MIS-C in comparison with those admitted with SARS-CoV-2 infection with other features such as COVID-19 pneumonia. Methods A multicentric prospective national registry including 47 PICUs was carried out. Data from children admitted with confirmed SARS-CoV-2 infection or fulfilling MIS-C criteria (with or without SARS-CoV-2 PCR confirmation) were collected. Clinical, laboratory and therapeutic features between MIS-C and non-MIS-C patients were compared. Results Seventy-four children were recruited. Sixty-one percent met MIS-C definition. MIS-C patients were older than non-MIS-C patients (p = 0.002): 9.4 years (IQR 5.5–11.8) vs 3.4 years (IQR 0.4–9.4). A higher proportion of them had no previous medical history of interest (88.2% vs 51.7%, p = 0.005). Non-MIS-C patients presented more frequently with respiratory distress (60.7% vs 13.3%, p < 0.001). MIS-C patients showed higher prevalence of fever (95.6% vs 64.3%, p < 0.001), diarrhea (66.7% vs 11.5%, p < 0.001), vomits (71.1% vs 23.1%, p = 0.001), fatigue (65.9% vs 36%, p = 0.016), shock (84.4% vs 13.8%, p < 0.001) and cardiac dysfunction (53.3% vs 10.3%, p = 0.001). MIS-C group had a lower lymphocyte count (p < 0.001) and LDH (p = 0.001) but higher neutrophil count (p = 0.045), neutrophil/lymphocyte ratio (p < 0.001), C-reactive protein (p < 0.001) and procalcitonin (p < 0.001). Patients in the MIS-C group were less likely to receive invasive ventilation (13.3% vs 41.4%, p = 0.005) but were more often treated with vasoactive drugs (66.7% vs 24.1%, p < 0.001), corticosteroids (80% vs 44.8%, p = 0.003) and immunoglobulins (51.1% vs 6.9%, p < 0.001). Most patients were discharged from PICU by the end of data collection with a median length of stay of 5 days (IQR 2.5–8 days) in the MIS-C group. Three patients died, none of them belonged to the MIS-C group. Conclusions MIS-C seems to be the most frequent presentation among critically ill children with SARS-CoV-2 infection. MIS-C patients are older and usually healthy. They show a higher prevalence of gastrointestinal symptoms and shock and are more likely to receive vasoactive drugs and immunomodulators and less likely to need mechanical ventilation than non-MIS-C patients

Impact of common cardio-metabolic risk factors on fatal and non-fatal cardiovascular disease in Latin America and the Caribbean: an individual-level pooled analysis of 31 cohort studies

Background: Estimates of the burden of cardio-metabolic risk factors in Latin America and the Caribbean (LAC) rely on relative risks (RRs) from non-LAC countries. Whether these RRs apply to LAC remains un- known. Methods: We pooled LAC cohorts. We estimated RRs per unit of exposure to body mass index (BMI), systolic blood pressure (SBP), fasting plasma glucose (FPG), total cholesterol (TC) and non-HDL cholesterol on fatal (31 cohorts, n = 168,287) and non-fatal (13 cohorts, n = 27,554) cardiovascular diseases, adjusting for regression dilution bias. We used these RRs and national data on mean risk factor levels to estimate the number of cardiovascular deaths attributable to non-optimal levels of each risk factor. Results: Our RRs for SBP, FPG and TC were like those observed in cohorts conducted in high-income countries; however, for BMI, our RRs were consistently smaller in people below 75 years of age. Across risk factors, we observed smaller RRs among older ages. Non-optimal SBP was responsible for the largest number of attributable cardiovascular deaths ranging from 38 per 10 0,0 0 0 women and 54 men in Peru, to 261 (Dominica, women) and 282 (Guyana, men). For non-HDL cholesterol, the lowest attributable rate was for women in Peru (21) and men in Guatemala (25), and the largest in men (158) and women (142) from Guyana. Interpretation: RRs for BMI from studies conducted in high-income countries may overestimate disease burden metrics in LAC; conversely, RRs for SBP, FPG and TC from LAC cohorts are similar to those esti- mated from cohorts in high-income countries

"Significados asociados a la actividad delictiva” en hombres que se encuentran privados de libertad, por delito de robo, en Centro de Detención Preventiva Santiago Sur

The following Seminar is orientated to understand the meanings that people outside the law give to their own criminal activities, primarily stealing, through the identification and connection between the emerging issues and the theoretical constructs made through this study. The identification and understanding of this topic is developed focusing on Occupational Therapy general views.To develop this qualitative research, the project takes place in Centro de Detención Preventiva ( Preventive detention center) Santiago Sur, Chile, with men between the ages of 27 and 35 years old, which are convicted for robbery. The information was collected from five semi-structured interviews, and analyzed with the Grounded Theory. This allows the review of emerging phenomena and compares them with the theoretical approach.The results indicate that the meanings related to stealing are correlated with different phenomena, like: psychosocial risk factors, criminal initiation and the influence of being part of social networks, exploratory behavior, psychosocial development, symbolic interaction and meaningful map, personal identity, premeditated action and motivation for stealing, self-concept and self-efficiency.After discovering and understanding the phenomena from the participant's point of view, it is clear to see two different ways for understanding the act of stealing, which differ from the meaning that the person gives to the act. On one hand, they see themselves as thieves and participate with the role. And on the other, they do not see themselves as thieves, they find an identity with the job, becoming the main activity in their lives.The analysis and results of the meanings associated to the act of robbery can be interesting for Occupational Therapy. This research includes key elements for this discipline and its development, including the motivation and personal subjectivity, bounds, relationships and the context for their development, making all together the meanings of each person.El presente estudio pretende comprender los significados que las personas transgresoras de ley, le otorgan a su propia actividad delictiva, específicamente al robo, mediante la identificación y relación de los temas emergentes durante este estudio, con constructos teóricos. La identificación y comprensión de estos temas, se realiza en torno a una visión general de Terapia Ocupacional.Para abordar esta investigación, de carácter cualitativo, se contextualiza el tema a estudiar en Centro de Detención Preventiva Santiago Sur, siendo los participantes hombres entre 27 y 35 años, que cumplen condena por delito de robo. La información recopilada, se extrae a partir de cinco entrevistas semi estructuradas, para ser luego analizadas a través de la Teoría Fundada, que permite revisar los fenómenos emergentes y ponerlos en discusión con los planteamientos teóricos.Los hallazgos obtenidos, señalan que los significados asociados al robo, se pueden relacionar a distintos fenómenos como; factores psicosociales de riesgo, inicio delictual e influencia y pertenencia a redes sociales, conducta exploratoria, procesos psicosociales, interacción simbólica y mapa significativo propio, identidad personal, acción preconcebida y motivaciones del robo, autoconcepto y autoeficacia.Al descubrir y analizar los fenómenos desde los participantes, emergieron dos formas de significar el robo, las cuales se diferencian según la relación que tiene el entrevistado con   este. En una de las categorías, se consideran ladrones, asumen este rol y se auto perciben como tales. En la otra, no se consideran a si mismos ladrones, identificándose con el trabajo, siendo esta la principal actividad en sus vidas.Al conocer y profundizar sobre los significados asociados al robo, se puede aportar a Terapia Ocupacional, ya que se consideran en la investigación elementos claves para esta disciplina y su desempeño, como son las motivaciones y la subjetividad de cada persona, los vínculos, relaciones y el contexto en que estas se dan, formando en conjunto los significados de cada persona

Live weight effect on the prediction of tissue composition in suckling lamb carcasses using the European Union scale

Forty-eight Manchega breed suckling lambs were slaughtered at 10, 12 and 14 kg live weight. Carcass degree of fatness was assessed by three assessors on carcass colour photographs, using the European Union scale for light lambs (EU) subdivided into 0.25-point intervals. Left half-carcasses were jointed and dissected into lean, fat and bone. Muscle percentage, bone percentage and whole fat percentage (obtained by addition of every fat depot subcutaneous fat, intermuscular fat, inguinal fat and kidney knob and channel fat) were determined. Ten kilograms group showed a higher number of variates significantly correlated to assessors' fatness scoring than 12 and 14 kg groups; no statistically significant regression was seen in 14 kg group. Results suggest that, as live weight increases, the utility of this method to predict carcass and joints tissue composition in suckling lamb carcasses decreases. EU scale associated with weight variates can really improve prediction of carcass composition. It would be interesting to extend this study in order to determine a similar effect on the prediction of heavier groups of carcasses. © 2005 Elsevier B.V. All rights reserved

Methods of carcass classification based on subjective assessments of carcass fatness and of carcass conformation Effect of sex on the prediction of tissue composition in carcasses of sucking lambs

Forty-eight sucking lambs (26 males and 22 females) of the Manchega breed were used in this work. Lambs were slaughtered at 10, 12 and 14 kg live weight. Carcass degree of fatness was assessed by three assessors from colour photographs of the carcasses, using the European Union scale for light lambs (EU), the Colomer-Rocher method (CF) and another new scale developed by our group (sucking lambs scale, SL). Carcass conformation was assessed according to the Colomer-Rocher method (CC). Fatness and conformation scales were divided to give 0.25 points in each interval. Left half-carcasses were jointed and dissected into lean, fat and bone. Muscle proportion, bone proportion and whole fat proportion (obtained by addition of every fat depot subcutaneous fat, intermuscular fat, inguinal fat and kidney knob and channel fat) were determined. Male and female carcasses showed a very different tissue composition both groups had statistically significant differences (P < 0.05) in 20 out of 25 tissue composition variates. Males showed a higher number of variates that were well correlated with assessors' scoring than females. Correlation coefficients between most of the tissue composition variates and assessors' scores were higher in males. Furthermore, the number of variates that were significantly correlated with assessors' scores was lower in females. Therefore, subjective methods for the estimation of carcass degree of fatness and of carcass conformation are poor predictors of tissue composition in female sucking lamb carcasses

Carcass classification in suckling lambs. Discrimination ability of the European Union scale

Forty-nine Manchega suckling lambs were used in this trial. Lambs were slaughtered at 10, 12 and 14 kg liveweight (cold carcass weight lower than 13 kg). The degree of fatness was assessed by three assessors on colour photographs of the carcasses, using the European Union scale for light lambs (EU), and another new scale developed in our laboratory (Suckling Lamb scale, SL). Carcass degree of fatness was reassessed using the same scales divided into 0.25 point-intervals (EUI, SLI). Carcasses were allocated into four groups by means of a tree classification algorithm (cluster analysis), according to 27 variates, namely muscle percentage, whole fat percentage, subcutaneous fat, intermuscular fat, kidney knob and channel fat percentage and muscle percentage, both in the carcass and in three joints (leg, best end neck plus loin, and shoulder). SL scale groups showed a higher number of variates well correlated to assessors' scoring than EU scale groups. Nevertheless, the EU scale showed significant between-groups differences in a higher number of variates (P<0.01). Using 0.25-points interval scales, EUI scale scoring was the best correlated to tissue composition. However, most variates were better correlated to dorsal fat thickness measurement (4 cm back from last rib and 4 cm from the carcass midline) than to assessors' scoring. All four groups in the tree classification were statistically different from one another, but assessors only were able to detect differences between whole fat percentage in group 1 and the rest. These results suggest that it is possible to improve the photographic standards of the EU method by using a 0.25 points interval scale. In abattoir conditions, the new SL method (1.0 point intervals) proved to be better. Measure of dorsal fat thickness proved to be a very good predictor of carcass tissue composition, but it is a more expensive measure. © 2002 Elsevier Science Ltd. All rights reserved

Carcass classification in suckling lambs. II. Comparison among subjective carcass classification methods Fatness scales and conformation scales with 0.25 point-intervals

Forty-nine Manchega breed suckling lambs were used. Carcass weight was less than 13 kg, and lambs were slaughtered at 10, 12 and 14 kg liveweight. Carcasses were classified by three assessors on colour photographs, by several classification methods the European Union scale for light lambs carcasses (EU), Colomer-Rocher methods for fatness (CF) and conformation (CC), and the new scale for suckling lambs (SL) developed by our research group. Carcasses were also assessed using these scales divided into 0.25 point-intervals (EU-25, CF-25, CC-25 and SL-25). A correlation analysis was made between assessors score and tissue composition in the carcass and in three joints (leg, best end of neck and loin, and shoulder). For all the methods studied 0.25 point scales were best correlated to tissue composition than 1.0 points-interval scales. When 1.0 point-interval scales were used the SL scale was best correlated to tissue composition. When 0.25 point-scales were used, the EU scale gave the best correlations. Conformation scale (CC) was useful to predict carcass composition, specially kidney knob and channel fat content. © 2003 Elsevier Ltd. All rights reserved
