Metal injected into tumors to boost radiotherapy, music against the sequelae of very premature babies and air pollution increase the risk of atherosclerosis. Here is the main news.
Cancer: metal injected into tumors to boost radiotherapy
Like every year, tens of thousands of doctors, researchers and scientists from all over the world are gathered in Chicago at the congress of theAmerican Society of Clinical Oncology (ASCO) to present their latest work in oncology. Injections of nanoparticles into tumors are among the 2019 innovations. A team from the Institut Curie in France caused a sensation by presenting one of its studies carried out on patients with cancers of the throat, larynx and mouth. To increase the effectiveness of their radiotherapy treatment, they injected nanoparticles of Hafnium (a metal) into the tumors of participants whose state of health and age did not allow chemotherapy to be considered. The injections were made the day before the radiotherapy sessions… To read more, click here.
Music against the sequelae of very premature babies
To fight against disorders of neurodevelopmental origin in very premature babies, linked in particular to learning, concentration or the management of emotions, researchers are testing the effects of music. Their results were published in the journal PNAS. The premature birth of a child interrupts its development in utero: its organs are present but they are immature. This mainly concerns four parts of the body: the brain, the lungs, the digestive tract and the arterial canal, hence many possible sequelae. “It was important that these musical stimuli be linked to the state of the baby, explains Lara Lordier, doctor in neurosciences at the HUG and the University of Geneva and director of the study.

Atherosclerosis: air pollution increases the risks
Permanent exposure to air pollution puts you at risk of atherosclerosis, according to a new study. We are talking here about smog, this thick fog formed of soot particles and water drops, in certain humid and industrial regions. To reach these conclusions, 6,619 people aged 45 to 84 were followed for 6.5 years. None of them had cardiovascular disease at the start of the experiment. They lived in six cities in the United States: Winston-Salem, New York City, Baltimore, Saint Paul, Chicago and Los Angeles. “We used statistical models to determine if there are significant associations between ozone exposure and atherosclerosis,” explains the study director.
