Impactos da fração inspirada de oxigênio e o desfecho clínico de pacientes COVID-19 em ventilação mecânica
No full textObjective: to evaluate the correlation between the average FiO2 and the outcome of these patients admitted to the Covid-19 ICU, as well as to analyze the time spent on ventilation, gender, age and days of hospitalization. Method: Retrospective, quantitative cohort, with patients with Covid-19 admitted to the intensive care unit of a University Hospital in Paraná-Brazil, from April 2020 to April 2021. Results: From the total sample (n=625) , the prevalence of deaths was 73.12%, mean age 61.18 years. The average time on mechanical ventilation was 11.97 days and the average FiO2 was 52.53%. FiO2 > 60% was associated with a higher risk of death (52%). Age over 45 years was associated with a higher risk of death. A lower risk of death was identified for prolonged days of hospitalization and MV. Conclusion: Excessive use of oxygen is a risk factor for worse outcomes. Age was not a predictor of higher FiO2 and effective weaning was shown to be a protective factor against high oxygen concentrations.Objetivo: evaluar la correlación entre la FiO2 promedio y el resultado de pacientes ingresados ??en la UCI Covid-19, así como analizar el tiempo dedicado a la ventilación, el sexo, la edad y los días de hospitalización. Método: Cohorte, cuantitativa y retrospectiva, con pacientes con Covid-19 ingresados ??en la UCI de un Hospital Universitario de Paraná-Brasil, de abril de 2020 a abril de 2021. Resultados: De la muestra total (n=625), se determinó la prevalencia de las defunciones fueron 73,12%, edad media 61,18 años. El tiempo promedio de ventilación mecánica fue de 11,97 días y la FiO2 promedio fue de 52,53%. FiO2 > 60% se asoció con un mayor riesgo de muerte (52%). La edad mayor de 45 años se asoció con un mayor riesgo de muerte. Se identificó un menor riesgo de muerte para días prolongados de hospitalización y VM. Conclusión: El uso excesivo de oxígeno es un factor de riesgo para peores resultados. La edad no fue un predictor de una mayor FiO2 y se demostró que el destete efectivo era un factor protector contra las altas concentraciones de oxígeno.Objetivo: avaliar a correlação entre a média FiO2 com o desfecho desses pacientes internados em UTI Covid-19, bem como analisar o tempo em regime ventilatório, sexo, idade e dias de internação. Método: Coorte retrospectiva, quantitativa, com pacientes com Covid-19 internados em UTI de um Hospital Universitário do Paraná-Brasil, no período de abril de 2020 a abril de 2021. Resultados: Do total da amostra (n=625), a prevalência de óbitos foi de 73,12%, média da idade de 61,18 anos. O tempo médio de ventilação mecânica foi de 11,97 dias e a média da FiO2 foi de 52,53%. A FiO2 > 60% foi associada ao maior risco de óbito (52%). Idade acima de 45 anos foi associado a maiores risco de evolução à óbito. Foi identificado menor risco de óbito para dias de internamento e VM prolongados. Conclusão: O uso excessivo de oxigênio é um fator de risco para piores desfechos. A idade não foi um preditor de maiores FiO2 e o desmame eficaz demonstrou-se como fator protetor a concentrações elevadas de oxigênio

Algeria in France: War and Defeat in Republican Culture
No full textAlgeria in France: War and Defeat in Republican Culture
The contention of this thesis is that the Algerian war of 1954-62 and Algeria’s subsequent independence have had a significant and lasting impact on the nature of French republicanism, and to a much greater extent than the historiography currently recognises. The Algerian war essentially altered the notion of French citizenship in a way which undermined the republican ideals of universalism and assimilation. By reconsidering the war and its aftermath within the broad context of French history since 1789, I argue that the founding of the Fifth Republic was not simply the culmination of French political history; it did not mark the end of the Revolution. Instead, it was itself a revolution and presented a fundamental challenge to republicanism’s original ideals of universalism and assimilation.
This thesis is a cultural history in the sense that its source material is derived primarily from novels and films, but its conclusions are socio-political. I identify an idiom of republican culture and trace the trends of republican historic and artistic representations of war and defeat. The basis of this study is longitudinal in the sense that it considers themes that have been present through modern French history. The three grandest themes are covered by the three chapters: citizenship, republicanism and the guerre franco-française. By considering these themes in relation to republican cultural representations of the Algerian war, this thesis identifies how the revolution in republicanism has been concealed and the history of the Franco-Algerian relationship has been rejected. This rejection has subsequently allowed the extreme right to control the race and immigration agenda because to challenge it requires a recognition of the revolution which occurred between 1959-1962
Reservoir computing with output feedback
No full textReinhart RF. Reservoir computing with output feedback. Bielefeld: Bielefeld University; 2011.A dynamical system approach to forward and inverse modeling is proposed. Forward and inverse models are trained in associative recurrent neural networks that are based on non-linear random projections. Feedback of estimated outputs into such reservoir networks is a key ingredient in the context of bidirectional association but entails the problem of error amplification. Robust training of reservoir networks with output feedback is achieved by a novel one-shot learning and regularization method for input-driven recurrent neural networks. It is shown that output feedback enables the implementation of ambiguous inverse models by means of multi-stable dynamics. The proposed methodology is applied to movement generation of robotic manipulators in a feedforward-feedback control framework
