Researchers have analysed the efficacy of the meningococcal serogroup B vaccine (4CMenB, Bexsero) in more than 1,500 children under five years of age in Spain. The research, published in the New England Journal of Medicine, shows that full vaccination was effective in preventing invasive meningococcal disease of both serogroup B and other serogroups in this child population. The vaccine, which had been sold privately in Spain since 2015, had already been included by several autonomous communities in their vaccination schedules. Last December, the Interterritorial Council of the National Health System (CISNS) approved its inclusion in the vaccination schedule for the whole of Spain.

Beta-blockers (β-blockers) are drugs to treat heart conditions that are also used for anxiety. According to research published in PLOS Medicine, periods of treatment with these drugs are associated with a lower risk of being charged by the police with a violent crime - a 13% lower risk than periods without treatment. The research, which included nearly 1.5 million people in Sweden between 2006 and 2013, does not support the use of these drugs to treat anxiety.

Nature's ban on publishing papers written by ChatGPT has brought several debates to the table: is it ethical to use it to produce science texts, and if so, should it sign them? Just as we don't make the Word proofreader a co-author of our articles, let's not make fools of ourselves by giving these new tools the status of co-authors as if they had an entity of their own.

A meta-analysis of 42 studies from 15 countries, including Spain, concludes that the covid-19 pandemic caused learning delays in school-aged children and a loss of knowledge equivalent to 35% of the learning of a school year.

The rate of death by suicide in Spain has increased between 2018 and 2021, according to a report presented today by the Complutense University of Madrid, the Centre for Biomedical Research in Mental Health Network (CIBERSAM) and the Hospital del Mar in Barcelona, which points to the influence of the pandemic in this increase. In 2021, a total of 4,003 people died from this cause, 5.5% more than in 2018. During the pandemic, mortality by suicide was greater among people living in large cities and provincial capitals. The report, which includes data from 2000 to 2021, also shows the increase in deaths by suicide that occurred during the period of the economic crisis, from 2008 to 2014.

A study published in the journal PLOS Medicine concludes that the development and academic outcomes of girls and boys conceived with in vitro fertilisation (IVF) are no different from those of children conceived naturally. The analysis is based on data from two national assessments in Australia, including more than 585,000 children born between 2005 and 2014 (more than 11,000 conceived by IVF). The first assessment measured the physical and emotional and cognitive health of children aged 4-6 years; the second focused on the numeracy and verbal skills of schoolchildren aged 7-9 years.
