Oil prices and inflation dynamics: Evidence from advanced and developing economies
2018
Abstract We study the impact of fluctuations in global oil prices on domestic inflation using an unbalanced panel of 72 advanced and developing economies over the period from 1970 to 2015. We find that a 10% increase in global oil inflation increases, on average, domestic inflation by about 0.4 percentage points on impact, with the effect vanishing after two years and being similar between advanced and developing economies. We also find that the effect is asymmetric, with positive oil price shocks having a larger effect than negative ones. The impact of oil price shocks, however, has declined over time due in large part to a more credible monetary policy and less reliance on energy imports.…
The effects of monetary policy shocks on inequality
2018
Abstract This paper provides new evidence of the effect of conventional monetary policy shocks on income inequality. We construct a measure of unanticipated changes in policy rates—changes in short-term interest rates that are orthogonal to unexpected changes in growth and inflation news—for a panel of 32 advanced and emerging market countries over the period 1990–2013. Our main finding is that contractionary monetary policy shocks increase income inequality, on average. The effect is asymmetric—tightening of policy raises inequality more than easing lowers it—and depends on the state of the business cycle. We find some evidence that the effect increases with the share of labor income and i…
Global Food Prices and Domestic Inflation: Some Cross-Country Evidence
2015
We study the impact of global food price shocks on domestic inflation in a large group of countries. For advanced economies, a 10% increase in global food inflation raises domestic inflation by about 0.5 percentage point after a year; however, the impact has declined over time and become less persistent. The global food price shocks of the 2000s had a much bigger impact on domestic inflation in emerging and developing economies than in advanced economies. This could reflect the smaller share of food in the consumption baskets in advanced economies. We also provide evidence that inflation expectations are more anchored in advanced than in emerging economies, which could also explain the smal…
Good clinical practice for the use of vasopressor and inotropic drugs in critically ill patients: state-of-the-science and expert consensus
2021
Vasopressors and inotropic agents are widely used in critical care. However, strong evidence supporting their use in critically ill patients is lacking in many clinical scenarios. Thus, the Italian Society of Anesthesia and Intensive Care (SIAARTI) promoted a project aimed to provide indications for good clinical practice on the use of vasopressors and inotropes, and on the management of critically ill patients with shock. A panel of 16 experts in the field of intensive care medicine and hemodynamics has been established. Systematic review of the available literature was performed based on PICO questions. Basing on available evidence, the panel prepared a summary of evidences and then wrote…
Risk indexes for studying interconnected earthing systems inside MV networks
2006
The paper presents a risk-evaluation-based approach to the issue of interconnection between the earth electrodes of the MV/LV substations within MV networks. After a short introduction on the interconnection between earthing systems, the paper proposes four risk indexes defined starting from the safety requirements given by CENELEC HD 63 7 S1. The indexes allow one to put in evidence, in a clear way, the benefits of the interconnection in terms of reduction of risk of critical electric shock for persons and of stress on the insulation of the LV devices in the presence of single line to earth faults and double earth faults inside MV/LV substations and single line to earth faults inside HV/MV…
T Cells Recognize an Immunodominant Epitope of Heat Shock Protein 65 in Kawasaki Disease
2000
Kawasaki disease (KD) is an acute systemic vasculitis of infancy and early childhood that is characterized by endothelial cell damage associated with T-cell activation. Lymphocytes infiltrating damaged tissues might be responsible for the disease through secretion of cytokines, such as tumor necrosis factor (TNF)-α, that could cause fever, as well as endothelial tissue damage. Debate is growing about the nature of antigen responsible for T-cell activation in KD. Bacillus Calmette Guerin (BCG) and purified protein derivative (PPD) hyper-responsiveness was observed in KD patients and this phenomenon was hypothetically ascribed to cross-reactivity between mycobacterial Heat Shock Protein (HSP)…
Higher Fluid Balance Increases the Risk of Death From Sepsis: Results From a Large International Audit
2017
Contains fulltext : 177598.pdf (Publisher’s version ) (Closed access) OBJECTIVES: Excessive fluid therapy in patients with sepsis may be associated with risks that outweigh any benefit. We investigated the possible influence of early fluid balance on outcome in a large international database of ICU patients with sepsis. DESIGN: Observational cohort study. SETTING: Seven hundred and thirty ICUs in 84 countries. PATIENTS: All adult patients admitted between May 8 and May 18, 2012, except admissions for routine postoperative surveillance. For this analysis, we included only the 1,808 patients with an admission diagnosis of sepsis. Patients were stratified according to quartiles of cumulative f…
"Me llaman el desaparecido" : coexistencia y continuidad entre la desaparición forzada y la desaparición social
2020
En este trabajo analizo una de las formas del desborde contemporáneo de la categoría de "desaparición", por la cual ésta pasa a designar formas de invisibilidad, exclusión y violencia muy diferentes a la que definía su marco originario. En particular, me detengo en el trazado de una relación de continuidad entre las formas de la desaparición forzada originaria -ejemplificada en el caso emblemático de la dictadura militar chilena- y las formas de "desaparición social" en las democracias liberales contemporáneas. A partir de la puesta en relación de conceptos políticos como campo, doctrina del shock o excepción, y del análisis de algunos productos culturales, exploramos la posibilidad de habl…
A comparison of the transcriptome of Drosophila melanogaster in response to entomopathogenic fungus, ionizing radiation, starvation and cold shock
2015
Background The molecular mechanisms that determine the organism's response to a variety of doses and modalities of stress factors are not well understood. Results We studied effects of ionizing radiation (144, 360 and 864 Gy), entomopathogenic fungus (10 and 100 CFU), starvation (16 h), and cold shock (+4, 0 and -4°C) on an organism's viability indicators (survival and locomotor activity) and transcriptome changes in the Drosophila melanogaster model. All stress factors but cold shock resulted in a decrease of lifespan proportional to the dose of treatment. However, stress-factors affected locomotor activity without correlation with lifespan. Our data revealed both significant similarities …
Skeletal muscle oedema and muscle fibre necrosis during septic shock. Observations with a porcine septic shock model
1994
In domestic pigs, intermitted application of Escherichia coli-endotoxin was used to create an animal model for a prolonged hypo- and hyperdynamic septic shock-like state and to investigate mechanisms of multiple organ failure. Here, we describe the changes in skeletal muscle after 18 h (2 animals) and 48 h (6 animals) of septic shock. Two pigs for each observation period that received physiologic saline solutions instead of endotoxin served as controls. The earliest lesions were endothelial cell damage with endomysial oedema and swelling of mitochondria in muscle fibres. With increasing degree of endothelial cell damage, pericytes showed degenerative changes with cytoplasmic fragmentation a…
