Screening tool may help diagnose mental disorders in early pregnancy

A recent study published in Acta Obstetricia et Gynecologica Scandinavica found that questions typically asked to new mothers to screen for depression after giving birth can also help to detect depressive symptoms and other mental disorders during early pregnancy. The questions are part of what’s called the Edinburgh Postnatal Depression Scale. In the study of […]

Geisinger research identifies genetic risk factor for stroke

DANVILLE, Pa. – A team of Geisinger researchers has identified a common genetic variant as a risk factor for stroke, especially in patients older than 65. Cerebral small vessel disease (SVD) causes about a quarter of ischemic strokes worldwide and is the most common cause of vascular dementia. SVD can manifest as lesions on […]

Response to infection therapy better understood thanks to a new technique

Infectious diseases are caused by pathogenic viruses, bacteria, fungi or parasites. The treatment of bacterial and fungal infections relies particularly on antimicrobial drugs, while the focus in treating viral infections is the alleviation of symptoms. Initial therapy for infection is often empiric and guided by clinical presentation. Its efficacy on the pathogen is, however, only […]

Genetic engineering without unwanted side effects helps fight parasites

Around a third of the world’s population carries Toxoplasma gondii, a parasite that puts people with a weakened immune system at risk and can trigger malformations in the womb. The single-celled pathogen also leads to economic losses in agriculture, with toxoplasmosis increasing the risk of abortion among sheep, for example. The parasite has a complex […]
