A review of 14 studies and data from more than 130 million patients has found an association between the use of drugs such as anti-inflammatory drugs, antibiotics and vaccines and a reduced risk of dementia. The authors recall that “the fact that a particular drug is associated with an altered risk of dementia does not necessarily mean that it causes or helps against it.” However, “pooling these huge health data sets provides a source of evidence that can help us decide which drugs to try first.” The research is published in the journal Alzheimer's and Dementia: Translational Research & Clinical Interventions. 

In a group of people at high cardiovascular risk, low to moderate wine consumption was associated with fewer cardiovascular events (cardiovascular death, myocardial infarction, stroke or heart failure), according to a study. The analysis uses urinary concentrations of tartaric acid, a substance found in grapes and grape derivatives, as a biomarker of wine consumption. It finds that consuming between three and 35 glasses per month was associated with fewer cardiovascular events than in people who consumed fewer than three or more than 35 glasses. The study, published in the European Heart Journal, included more than 1,200 participants from Spain's PREDIMED study with an average age of 68 years.

According to a study on the number of pedestrian accidents in Great Britain between 2013 and 2017, published in the Journal of Epidemiology & Community Health, the risk of pedestrian crashes was twice as high for electric and hybrid vehicles as for petrol and diesel vehicles.
