Uenighetsdramaturgier
2019
Hvordan kan samtidsteater bli arena, laboratorium og katalysator for «uenighetsfellesskaper» (Iversen, 2014)? I denne artikkelen drøfter jeg teatersituasjonens potensial for uenighetsfellesskap og ser uenighet i forestillinger i relasjon til uenighet om forestillinger før jeg analyserer to eksempler på «uenighetsdramaturgier». I de kontekstsensible analysene undersøker jeg hvordan publikumets interne uenighet kommer til uttrykk, og hvordan det dramaturgisk legges til rette for denne uenigheten.
Evaluación mediante micro CT de la eficacia del retratamiento de los conductos radiculares utilizando el microscopio clínico y los instrumentos ultra…
2018
El objetivo de este estudio fue comparar la eficacia y el tiempo de las técnicas, rotativas, manuales y recíprocas para eliminar el material de la obturación de los conductos radiculares, utilizando imágenes de microtomografía computarizada. Materiales y métodos: 99 diente humanos unirradiculares con conductos ovales, fueron instrumentados con el Sistema ProTaper Gold hasta la lima F2 según la técnica de crown-down y obturados con puntas de Gutacore Nº25 y sellador AH Plus. Las muestras se dividieron al azar en tres grupos de 33 dientes de cada uno. Después, los conductos radiculares fueron desobturados con limas de ProTaper R; Grupo 1, limas manuales de Hedstroem #25 y #30 y #35 con fresas…
The Global Side of the Investment-Saving Puzzle
2009
In this paper, we reexamine the long-standing and puzzling correlation between national saving and investment in industrial countries. We apply an econometric methodology that allows us to separate idiosyncratic correlation at the country level from correlation at the global level. In a major break with the existing literature, we find no evidence of a long-run relationship in the idiosyncratic components of saving and investment. We also find that the global components in saving and investments commove, indicating that they react to shocks of a global nature.
Predicting resistant etiology in hospitalized patients with blood cultures positive for Gram-negative bacilli
2018
Abstract Objective To develop a risk-scoring tool to predict multidrug-resistant (MDR) etiology in patients with bloodstream infections (BSI) caused by Gram-negative bacilli (GNB). Methods A prospective multicenter study analyzed patients with BSI hospitalized in 31 Internal Medicine wards in Italy from March 2012 to December 2012. Patients with BSI caused by MDR-GNB (non-susceptible to at least one agent in three antimicrobial categories) were compared to those with BSI due to susceptible GNB. A logistic regression to identify predictive factors of MDR-GNB was performed and the odds ratio (OR) were calculated. A score to predict the risk of MDR was developed. Results Of 533 BSI episodes, 2…
DALI: Defining Antibiotic Levels in Intensive Care Unit Patients: Are Current -Lactam Antibiotic Doses Sufficient for Critically Ill Patients?
2014
Background. Morbidity and mortality for critically ill patients with infections remains a global healthcare problem. We aimed to determine whether α-lactam antibiotic dosing in critically ill patients achieves concentrations associated with maximal activity and whether antibiotic concentrations affect patient outcome.Methods. This was a prospective, multinational pharmacokinetic point-prevalence study including 8 α-lactam antibiotics. Two blood samples were taken from each patient during a single dosing interval. The primary pharmacokinetic/pharmacodynamic targets were free antibiotic concentrations above the minimum inhibitory concentration (MIC) of the pathogen at both 50% (50% f TMIC) an…

Improving the material quality of silicon ingots by aluminum gettering during crystal growth
2016
We present a method for the purification of silicon ingots during the crystallization process that reduces significantly the width of the low charge carrier lifetime region at the ingot top. The back-diffusion of impurities from the ingot top is suppressed by adding a small amount of pure aluminum into the silicon melt right at the end of the solidification. We study the aluminum gettering effect by instrumental neutron activation analysis (INAA) and Fei imaging. Furthermore, we present a model for aluminum gettering of Fe in the silicon ingot that is in agreement with literature data for aluminum gettering at lower temperature. The distribution of iron in the ingots with and without alumin…
Drug Resistance in Salmonella enterica ser. Typhimurium Bloodstream Infection, Malawi
2014
To the Editor: Salmonella enterica serotype Typhimurium is one of the most common causes of bloodstream infection in sub-Saharan Africa (1). Among adults, the principal risk factor for invasive nontyphoidal Salmonella (iNTS) disease is advanced HIV infection; up to 44% of HIV-infected patients experience bacteremic recurrence through recrudescence of the original infection (2,3). Epidemics of iNTS disease in sub-Saharan Africa have been associated with a novel genotype of S. enterica ser. Typhimurium of multilocus sequence type (ST) 313 that is rarely seen outside the region and is associated with multidrug resistance (MDR) to chloramphenicol, cotrimoxazole, and ampicillin (4,5). As a conse…
Bloodstream Infections in Hospitalized Patients with COVID-19: A Systematic Review and Meta-Analysis
2021
Background: Little is known about the occurrence of bloodstream infections in hospitalized patients with COVID-19 and the related clinical consequences. The aim of this systematic review and meta-analysis was to estimate the pooled occurrence of BSIs among hospitalized patients with COVID-19 and mortality of this patient population. Methods: A systematic search was performed on PubMed, EMBASE, and Web of Science from inception to 19 April 2021. The primary outcome was the occurrence of BSIs among hospitalized patients with COVID-19. The secondary outcome was mortality at the longest available follow-up. Results: Forty-six studies met the inclusion criteria, with a total of 42,694 patients e…
