Undiagnosed childhood cancers, injections into the brain to cure Parkinson's and HIV

One out of every two children diagnosed with cancer worldwide is not diagnosed and treated, injections into the brain could regenerate the parts damaged by Parkinson's disease and a new discovery has been made in the treatment of HIV. Here is the essence of the news.

Cancer: One in two children worldwide is neither diagnosed nor treated

In 2015 around the world, nearly half of all children affected by cancer have not been diagnosed, and therefore have not received adequate treatment. This is the alarming finding of a new US study published in The Lancet Oncology. According to its lead author Prof. Zachary Ward of Harvard TH Chan School of Public Health in Massachusetts, statistics suggest up to 397,000 new cases of childhood cancer each year. However, the national registers count only 224 000. 45%, or 172 000 cases of childhood cancer would escape any diagnosis. More information in our article.

Parkinson's: curing the disease with injections into the brain

A treatment directly injected into the brain has effectively treated Parkinson's disease, according to a new clinical trial. Dopaminergic neurons, which the neurological disease degrades, could be regenerated. Six patients first participated in the pilot study to evaluate the safety of the therapeutic approach. Another 35 people with Parkinson's disease then participated in a nine-month experiment, half of whom received either placebo or treatment. Appraisal: the area of ​​the brain affected by the disease regenerated in all patients who received the injections, while people on placebo showed no improvement in their condition.

HIV: tailor-made proteins to help antibodies fight the virus

Are researchers coming to a new stage in the development of an HIV vaccine? This is the hope of a new study by Pennsylvania State University (Penn State University). In an article published in the journal Nature Communications, his authors say they have managed to use computer modeling to create proteins that mimic the different surface characteristics of HIV by infiltrating its protective coating. Tested on rabbits, these proteins have allowed rodents to develop antibodies capable of binding to the AIDS virus to better combat it. We tell you more in our article.
