A study conducted with nearly 58,000 boys and girls revealed that increased television or DVD screen time starting from 12 months of age had a negative impact on later development, as reported by JAMA Pediatrics.
On 5 April, the UK National IHR Focal Point informed WHO of an increase in severe myocarditis in neonates associated with enterovirus infection in Wales (UK). Between June 2022 and April 2023, ten hospitalised neonates with a positive PCR for enterovirus were found to have myocarditis. Seven of the ten cases were confirmed to have coxsackievirus B3 or coxsackievirus B4. As of 5 May 2023, one patient remained hospitalised and one patient had died. According to the WHO statement, although enterovirus infections are common in neonates and infants, the reported increase in myocarditis - inflammation of heart muscle tissue - with severe outcome associated with enterovirus infection is unusual.
A phase 2 clinical trial has analysed the safety and efficacy of adding immunotherapy to traditional chemotherapy to treat a subtype of acute lymphoblastic leukaemia in children under one year of age. This subtype of leukaemia, although rare in absolute terms, is the most common in children of this age, and its prognosis in this age group had not improved in recent years. The immunotherapy used, a bispecific antibody that binds to tumour cells on the one hand and T lymphocytes on the other, improved two-year survival from 66% to 93% in treated patients, according to The New England Journal of Medicine (NEJM).
Three studies published today in Nature explore the link between the cases of childhood hepatitis of unknown origin that have occurred since 2022 mainly in the UK and the US and an adeno-associated virus. The papers do not settle the question and further studies will be needed to confirm or exclude the hypothesis.
People who had a lower respiratory tract infection—such as bronchitis or pneumonia—before the age of two have twice the risk of premature death from respiratory disease in adulthood, according to a study published in The Lancet. The research is based on long-term data from over 3,500 people born from 1946 onwards in England, Scotland and Wales. According to the study, one in five premature deaths in this representative sample could be due to respiratory infections. The team adjusted their estimate by taking into account factors such as socioeconomic status in childhood and smoking in adulthood.
A study in California has found that 41% of deaths in the first year of life are due to genetic diseases. This percentage is higher than previously thought. According to the authors, strategies to improve neonatal genetic diagnosis may reduce infant mortality, as this diagnosis is sometimes missed or arrives late. The research is published in JAMA Network Open.
A series on breastfeeding published today in The Lancet highlights the economic and political power of formula companies, examines their marketing practices and the impact this has on the health of mothers and children.
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.
Bubble boy syndrome is a very serious condition caused by combined immunodeficiency. It is sometimes caused by certain mutations in the gene that codes for the Artemis protein. A phase I-II clinical trial has tested a gene therapy that adds a correct copy of the gene. The results are published in the journal NEJM.
The World Health Organisation (WHO) has issued a statement recommending skin-to-skin contact immediately after birth to improve the survival of premature and low birth weight babies. Until now, in clinical practice it was common for the first phase after birth to take place in the incubator.
