Oral and gut bacteria in stroke patients associated with worse prognosis and mortality

A common bacteria usually found in the mouth and gastrointestinal tract, Streptococcus anginosis, may be abundant in the guts of people with stroke and is associated with a worse prognosis and increased risk of death, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2025.

Study links epigenetic mechanism to placental blood vessel development

If the development of blood vessels in the placenta is impaired, fetal growth retardation may result. Scientists from the German Cancer Research Center (DKFZ) and the Mannheim Medical Faculty of Heidelberg University discovered that the correct development of functioning blood vessels in the mouse placenta is controlled epigenetically: One of the enzymes that modify gene activity using methyl groups is responsible.

Retina vascular fingerprint offers non-invasive way to predict stroke risk

A vascular 'fingerprint' on the light sensitive tissue layer at the back of the eye-the retina-can predict a person's risk of stroke as accurately as traditional risk factors alone, but without the need for multiple invasive lab tests, finds research published online in the journal Heart.
