Following the agreement reached a few months ago between the European Parliament and Council, in today’s plenary session the European Parliament has approved a provisional political agreement with EU countries that includes new requirements to improve air quality by 2030. The agreement sets stricter targets and limits for several pollutants that have a serious impact on health, including particulate matter (PM2.5, PM10), NO2 (nitrogen dioxide) and SO2 (sulfur dioxide). Before being published in the Official Journal of the European Union, the law now must be adopted by the Council. EU countries will have two years to implement the new standards

A US study has found that patients treated by female physicians have lower rates of mortality and hospital readmission than those treated by male physicians. The study, published in the Annals of Internal Medicine and involving more than 700,000 patients over the age of 65, found that the effects were even greater when female patients were treated by female physicians.

The Copernicus Climate Change Service, together with the World Meteorological Organisation, publishes the report on the state of Europe's climate in 2023. According to their findings, last year was one of the hottest on record, with a record number of extreme heat stress days and widespread flooding. According to their calculations, heat-related mortality has increased by 30 % over the last 20 years.

Researchers have found specific antibodies in the blood of patients years before they showed symptoms of multiple sclerosis. This group of antibodies was present in 10% of the 250 people who later developed the disease, and were part of a sample of over 10 million US military personnel. The finding could have potential for early detection of multiple sclerosis, says the research team in a paper published in Nature Medicine. 

According to a study published today by The BMJ, people with dementia who are treated with antipsychotics are at increased risk of serious adverse events such as stroke, blood clots, myocardial infarction, heart failure, fractures, pneumonia, and acute kidney injury, compared with those who do not take them, . These findings extend the harms previously associated with the use of these drugs on these patients. 

The global economy could lose, on average, 19% of income by 2049 due to increased carbon emissions over the past four decades, says an analysis published in Nature. To estimate the future economic damages of climate change, the authors used temperature and precipitation data for 1,600 regions worldwide in the past 40 years. Low-income countries will be more affected by these losses than higher-income countries, the authors warn. 

Although breast cancer mortality has reduced by more than 40% in most high-income countries, a Lancet commission warns that one million people will die from the disease by 2040, especially in low- and middle-income countries. The authors highlight some of the knowledge gaps that persist about the disease, such as the lack of knowledge about the number of patients living with metastatic breast cancer and their needs, or the costs associated with breast cancer - including physical, psychological, social and economic costs - which, according to the authors, are immense but underestimated, and not adequately reflected in global health indicators. 

A monoclonal antibody called prasinezumab reduces the worsening of motor symptoms in people with Parkinson's disease who have rapidly progressive disease, according to an analysis of a phase 2 clinical trial published in Nature Medicine. These findings suggest that clinical efficacy of prasinezumab, which works by binding to alpha-synuclein protein aggregates, is seen after one year of treatment in such patients. According to the authors, more research is needed to determine whether the antibody can be effective in people with slower disease progression after longer periods of treatment. 

Researchers have developed a new method to produce a heat-resistant plastic from renewable plant materials. They also claim that it is easily recyclable, decomposing into methanol, which would allow it to enter the circular economy. The research is published in the journal Science. 

The ovarian cycle is regulated by internal circadian rhythms rather than external processes, says a study published in Science Advances. Using menstrual cycle data from some 3,000 women in Europe and North America, the authors add that the influence of the lunar cycle on women's menstrual cycle is weak, but significant.
