With just days to go before COP28 kicks off in Dubai -a major city in the oil-rich United Arab Emirates- climate experts are torn between mistrust and hope that world leaders will reach ambitious agreements to combat the climate crisis.
Since mid-October, northern China has reported an increase in influenza-like illness compared to the same period in the previous three years. On 21 November, the media and the ProMED system reported outbreaks of pneumonia of undiagnosed cause in children in northern China. According to the World Health Organization (WHO), it is unclear whether these are related to the overall increase in respiratory infections previously reported by the Chinese authorities or are separate episodes. In a statement, the WHO has officially requested detailed information from China on this increase in respiratory illnesses and outbreaks of childhood pneumonia.
In Spain, both in the child and adult populations, excess weight and obesity are more prevalent among men. Additionally, lower educational levels, lower income, disability, and the presence of individuals with obesity in the household are factors associated with a higher prevalence of excess weight and obesity. These are some of the conclusions drawn from two scientific articles and two complementary reports prepared by the National Center for Epidemiology of the Carlos III Health Institute and the Spanish Agency for Food Safety and Nutrition (AESAN). The data is derived from the ENE-COVID survey, which investigated the seroprevalence of COVID-19 infection in Spain.
Babies' brains specialise in their native language from pregnancy, according to a study carried out in France. The research team used encephalograms to measure the brain activity of 33 infants born to French-speaking mothers while listening to a story in French, English or Spanish. The results provide "the most compelling evidence to date that language experience already shapes the functional organization of the infant brain, even before birth," the authors write in Science Advances.
A fatty acid present in the meat and dairy products of grazing animals, such as cows and sheep – trans-vaccenic acid (TVA) – enhances the ability of CD8+ T cells to infiltrate tumors and eliminate cancer cells, according to a new study conducted by researchers from the University of Chicago (USA), published today in the journal Nature.
Apps developed to treat depression may be beneficial in the management of severe and moderate cases. This is the conclusion of a review and meta-analysis that included 13 studies with up to 16 different apps. The results are published in the journal JAMA Network Open.
Biosimilars work in a similar way to biologics - which are made from living cells and are very complex and expensive - such as insulin, growth hormone, vaccines and monoclonal cancer antibodies. We explain what savings biosimilars bring to the healthcare system and what the process is to ensure that their quality, efficacy and safety are equivalent to those of the reference medicine.
The European Commission will renew the authorisation of the pesticide glyphosate in the European Union for 10 years, subject to "new restrictions and conditions". Following EU procedure, the announcement was made after member states failed to reach the majority required to renew or refuse approval.
A dietary shift from animal-based foods, such as red or processed meat and eggs, to plant-based foods, such as nuts, pulses and whole grains, is associated with a reduced risk of death and diabetes or cardiovascular disease. For example, replacing 50 grams of processed meat per day with 28-50 grams of nuts is associated with a 27% decrease in cardiovascular risk. These are the conclusions of a systematic review of 37 studies published in the journal BMC Medicine.
A review of 25 studies conducted over nearly 50 years has found an association between insecticide exposure and lower sperm concentration. According to the authors, "insecticides are a public health concern for all men, who are exposed mainly through consumption of contaminated food and water". The results are published in the journal Environmental Health Perspectives.
