Envisioning An Imperial Outpost: The Colonial City And Naval Base of Singapore In Anglo-American Travel And World Affairs Writing, 1900-1942
ABSTRACT
This thesis analyzes and compares depictions of Singapore and British Malaya from the turn of the twentieth century to 1942, the year the colonial city and naval base fell to Japanese forces. While many studies have looked forward to decolonization after the fall of Singapore, this study looks back to the crucial decades before the Second World War. The primary sources for the study are selected articles and books by American and British journalists, travel writers, and world-affairs observers. These sources show a gradual shift in focus from Singapore as a thriving commercial hub and culturally diverse colonial city to a strategic naval base. The British, the Australians, the Dutch, and the Americans seemed to pin their hopes on the base as a counter to the rise of Japan. As the situation worsened before the end of 1941, the sources indicate the beginnings of a transition from British to American hegemony in Asia Pacific
Hyperoxemia and excess oxygen use in early acute respiratory distress syndrome : Insights from the LUNG SAFE study
Publisher Copyright: © 2020 The Author(s). Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Concerns exist regarding the prevalence and impact of unnecessary oxygen use in patients with acute respiratory distress syndrome (ARDS). We examined this issue in patients with ARDS enrolled in the Large observational study to UNderstand the Global impact of Severe Acute respiratory FailurE (LUNG SAFE) study. Methods: In this secondary analysis of the LUNG SAFE study, we wished to determine the prevalence and the outcomes associated with hyperoxemia on day 1, sustained hyperoxemia, and excessive oxygen use in patients with early ARDS. Patients who fulfilled criteria of ARDS on day 1 and day 2 of acute hypoxemic respiratory failure were categorized based on the presence of hyperoxemia (PaO2 > 100 mmHg) on day 1, sustained (i.e., present on day 1 and day 2) hyperoxemia, or excessive oxygen use (FIO2 ≥ 0.60 during hyperoxemia). Results: Of 2005 patients that met the inclusion criteria, 131 (6.5%) were hypoxemic (PaO2 < 55 mmHg), 607 (30%) had hyperoxemia on day 1, and 250 (12%) had sustained hyperoxemia. Excess FIO2 use occurred in 400 (66%) out of 607 patients with hyperoxemia. Excess FIO2 use decreased from day 1 to day 2 of ARDS, with most hyperoxemic patients on day 2 receiving relatively low FIO2. Multivariate analyses found no independent relationship between day 1 hyperoxemia, sustained hyperoxemia, or excess FIO2 use and adverse clinical outcomes. Mortality was 42% in patients with excess FIO2 use, compared to 39% in a propensity-matched sample of normoxemic (PaO2 55-100 mmHg) patients (P = 0.47). Conclusions: Hyperoxemia and excess oxygen use are both prevalent in early ARDS but are most often non-sustained. No relationship was found between hyperoxemia or excessive oxygen use and patient outcome in this cohort.

A comprehensive analysis of factors related to carmustine/bevacizumab response in recurrent glioblastoma
Purpose Patients with recurrent glioblastoma (rGBM) have a poor prognosis, with survival ranging from 25 to 40 weeks.
Antiangiogenic agents are widely used, showing a variable response. In this study, we explored the efcacy of carmustine
plus bevacizumab (BCNU/Bev) for treating rGBM.
Methods/patients
In this study, we assessed 59 adult patients with histologically confrmed rGBM who were treated with
BCNU/Bev as second-line regimen. The response rate (RR), progression-free survival (PFS) and overall survival (OS)
were evaluated according to their molecular expression profle, including CD133 mRNA expression, MGMT methylation
(pMGMT), PDGFR amplifcation, YKL40 mRNA expression, IDH1/2 condition, p53 and EGFRvIII mutation status.
Results
Median follow-up was 18.6 months, overall RR to the combination was 56.3%, and median PFS was 9.0 months
(95% CI 8.0–9.9). OS from time of diagnosis was 21.0 months (95% CI 13.2–28.7) and from starting BCNU/Bev it was
10.7 months (95% CI 9.5–11.8). IDH1/2 mutations were found in 30.5% of the patients, pMGMT in 55.9% and high CD133
mRNA expression in 57.6%. Factors which positively afected PFS included performance status (p=0.015), IDH+ (p=0.05),
CD133 mRNA expression (p=0.009) and pMGMT+ (p=0.007). OS was positively afected by pMGMT+ (p=0.05). Meanwhile, YKL40 negatively afected PFS (p=0.01) and OS (p=0.0001). Grade≥3 toxicities included hypertension (22%) and fatigue (12%).
Conclusions
BCNU/Bev is a safe and tolerable treatment for rGBM. Patients with MGMT+/IDH+ derive the greatest beneft from the treatment combination in the second-line setting. Nonetheless, high YKL40 expression discourages the use of
antiangiogenic therapy
Immunocompromised patients with acute respiratory distress syndrome : Secondary analysis of the LUNG SAFE database
The aim of this study was to describe data on epidemiology, ventilatory management, and outcome of acute respiratory distress syndrome (ARDS) in immunocompromised patients. Methods: We performed a post hoc analysis on the cohort of immunocompromised patients enrolled in the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG SAFE) study. The LUNG SAFE study was an international, prospective study including hypoxemic patients in 459 ICUs from 50 countries across 5 continents. Results: Of 2813 patients with ARDS, 584 (20.8%) were immunocompromised, 38.9% of whom had an unspecified cause. Pneumonia, nonpulmonary sepsis, and noncardiogenic shock were their most common risk factors for ARDS. Hospital mortality was higher in immunocompromised than in immunocompetent patients (52.4% vs 36.2%; p < 0.0001), despite similar severity of ARDS. Decisions regarding limiting life-sustaining measures were significantly more frequent in immunocompromised patients (27.1% vs 18.6%; p < 0.0001). Use of noninvasive ventilation (NIV) as first-line treatment was higher in immunocompromised patients (20.9% vs 15.9%; p = 0.0048), and immunodeficiency remained independently associated with the use of NIV after adjustment for confounders. Forty-eight percent of the patients treated with NIV were intubated, and their mortality was not different from that of the patients invasively ventilated ab initio. Conclusions: Immunosuppression is frequent in patients with ARDS, and infections are the main risk factors for ARDS in these immunocompromised patients. Their management differs from that of immunocompetent patients, particularly the greater use of NIV as first-line ventilation strategy. Compared with immunocompetent subjects, they have higher mortality regardless of ARDS severity as well as a higher frequency of limitation of life-sustaining measures. Nonetheless, nearly half of these patients survive to hospital discharge. Trial registration: ClinicalTrials.gov, NCT02010073. Registered on 12 December 2013

Comprensión y Producción de Lenguaje I - HU543 - 202101
Descripción:
Comprensión y Producción de Lenguaje 1 es un curso de primer ciclo, que busca desarrollar las habilidades
vinculadas con la comprensión lectora y la redacción de textos escritos formales y adecuados a una situación
comunicativa determinada. Por ello, durante el curso, las actividades posibilitarán que el estudiante reflexione
sobre cómo el lenguaje es una herramienta que nos permite entender la realidad (comprensión) y comunicar
adecuadamente nuestras ideas sobre ella (producción). Esta reflexión se realizará con énfasis en el uso del
lenguaje en las redes sociales, espacio que se ha constituido como un nuevo lugar para la divulgación de asuntos
diversos: desde temas de ocio o entretenimiento hasta temas académicos, científicos y políticos. En ese sentido,
este curso propone que el alumno asuma el rol de un ciudadano crítico, es decir, aquella persona que no solo
consume información, sino que produce contenido a partir de una investigación en fuentes confiables.
Considerando lo explicado, nuestros alumnos no solo serán capaces de redactar un texto escrito formal de
acuerdo con las necesidades comunicativas del ámbito universitario y de la sociedad actual, sino que podrán
transformarlo en un texto multimodal (el cual involucra diferentes medios de comunicación: visual, auditivo,
imagen, texto, entre otros) que tenga sentido en las redes sociales, lugar de interacción real con sus lectores.
Estos productos comunicativos deberán presentar una organización conveniente, un desarrollo sólido y
suficiente (lo que implica una lectura crítica de las fuentes de información), y una escritura acorde con la
normativa vigente.

International Nosocomial Infection Control Consortiu (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module
We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care–associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line–associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN
Validation and utility of ARDS subphenotypes identified by machine-learning models using clinical data: an observational, multicohort, retrospective analysis
International audienceTwo acute respiratory distress syndrome (ARDS) subphenotypes (hyperinflammatory and hypoinflammatory) with distinct clinical and biological features and differential treatment responses have been identified using latent class analysis (LCA) in seven individual cohorts. To facilitate bedside identification of subphenotypes, clinical classifier models using readily available clinical variables have been described in four randomised controlled trials. We aimed to assess the performance of these models in observational cohorts of ARDS. Methods: In this observational, multicohort, retrospective study, we validated two machine-learning clinical classifier models for assigning ARDS subphenotypes in two observational cohorts of patients with ARDS: Early Assessment of Renal and Lung Injury (EARLI; n=335) and Validating Acute Lung Injury Markers for Diagnosis (VALID; n=452), with LCA-derived subphenotypes as the gold standard. The primary model comprised only vital signs and laboratory variables, and the secondary model comprised all predictors in the primary model, with the addition of ventilatory variables and demographics. Model performance was assessed by calculating the area under the receiver operating characteristic curve (AUC) and calibration plots, and assigning subphenotypes using a probability cutoff value of 0·5 to determine sensitivity, specificity, and accuracy of the assignments. We also assessed the performance of the primary model in EARLI using data automatically extracted from an electronic health record (EHR; EHR-derived EARLI cohort). In Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG SAFE; n=2813), a multinational, observational ARDS cohort, we applied a custom classifier model (with fewer variables than the primary model) to determine the prognostic value of the subphenotypes and tested their interaction with the positive end-expiratory pressure (PEEP) strategy, with 90-day mortality as the dependent variable. Findings: The primary clinical classifier model had an area under receiver operating characteristic curve (AUC) of 0·92 (95% CI 0·90–0·95) in EARLI and 0·88 (0·84–0·91) in VALID. Performance of the primary model was similar when using exclusively EHR-derived predictors compared with manually curated predictors (AUC=0·88 [95% CI 0·81–0·94] vs 0·92 [0·88–0·97]). In LUNG SAFE, 90-day mortality was higher in patients assigned the hyperinflammatory subphenotype than in those with the hypoinflammatory phenotype (414 [57%] of 725 vs 694 [33%] of 2088; p<0·0001). There was a significant treatment interaction with PEEP strategy and ARDS subphenotype (p=0·041), with lower 90-day mortality in the high PEEP group of patients with the hyperinflammatory subphenotype (hyperinflammatory subphenotype: 169 [54%] of 313 patients in the high PEEP group vs 127 [62%] of 205 patients in the low PEEP group; hypoinflammatory subphenotype: 231 [34%] of 675 patients in the high PEEP group vs 233 [32%] of 734 patients in the low PEEP group). Interpretation: Classifier models using clinical variables alone can accurately assign ARDS subphenotypes in observational cohorts. Application of these models can provide valuable prognostic information and could inform management strategies for personalised treatment, including application of PEEP, once prospectively validated.
