A study conducted at Pontifical Catholic University in Santiago, Chile, explored the neural mechanisms underlying impulsive choices. The researchers focused on the activity in the Nucleus Accumbens (NAc), the orbitofrontal cortex (OFC), and the dorsolateral striatum (DLS).

A recent report from the University of Chile discusses the epidemiology and potential role of respiratory viral infections in children with cancer and febrile neutropenia, as well as in children undergoing hematopoietic stem cell transplantation. The use of molecular diagnostic techniques has allowed for early detection of respiratory viral infections, leading to more rational use of antimicrobials in this vulnerable population. Recent randomized clinical studies have shown that in selected patients with negative bacterial cultures, it is safe and effective to discontinue antimicrobials. However, more evidence is needed for a similar indication in children undergoing hematopoietic stem cell transplantation with viral respiratory infection episodes. Understanding the role of respiratory viral infections in immunocompromised children may contribute to a more rational use of antimicrobials and help decrease antimicrobial resistance in this population.

A study conducted by the University of Chile examined the effectiveness of alcohol warning labels on purchase decisions. The study involved 7,758 adults who were randomly assigned to one of six warning labels: no-warning, pregnant/lactating, drinking-driving, general cancer risk, combined warnings, and assorted warnings. The results showed that participants exposed to the general cancer risk warning were most likely to decrease their alcoholic choices, followed by those in the pregnancy/lactation warning condition. The study suggests that general cancer risk warnings are more effective at reducing alcohol purchase decisions compared to warnings for specific groups or multiple warnings. The researchers also recommend considering other policies to address alcohol-related risks. [Extracted from the article]
