A study published in the European Heart Journal shows that people with type 1 and type 2 diabetes have a higher risk of sudden cardiac death than those without these diseases. In addition, their life expectancy is lower. The research analysed data from 6,862 cases of sudden cardiac death in Denmark in 2010, and concluded that the incidence of these deaths is 3.7 times higher in people with type 1 diabetes than in the general population, and 6.5 times higher in people with type 2 diabetes. Those under the age of 50 were at the highest risk.

In an analysis published by The Lancet Global Health, a panel of specialists urges the medical community to recognize type 5 diabetes as a disease distinct from other types of diabetes. This form of the disease —first described in 1955 and whose name “type 5” was recognized by the International Diabetes Federation in April 2025— affects 25 million people with a low body mass index, mainly in low- and middle-income countries, according to the authors' estimates. People with type 5 diabetes do not produce enough insulin, but their bodies process insulin normally. In addition, they do not usually suffer from ketoacidosis —an acute metabolic complication of diabetes— and their immune systems do not attack the pancreas. 

The Karolinska Institute has awarded the Nobel Prize in Medicine or Physiology to Victor Ambros and Gary Ruvkun for the discovery of microRNAs, small RNA fragments that do not contain instructions for making proteins but instead participate in the regulation of gene expression. Their role is fundamental in processes such as cell differentiation, and their alteration can influence diseases like cancer.
