Late third trimester ultrasound may detect missed fetal abnormalities

A study of over 50,000 pregnancies reveals that late third trimester ultrasounds can identify previously undetected fetal abnormalities in 0.5% of cases. This benefit highlights the importance of these scans for detecting abnormalities that were missed in earlier first and/or second trimester exams.

Large income change associated with cardiovascular disease risk

A significant association between changes in income and cardiovascular disease (CVD) risk was found in this observational study. Participants who experienced a 50% or more decrease in income were at higher risk of developing CVD, including heart attack, coronary heart disease, and stroke, over an average follow-up period of 17 years.

CNIO and University of Wurzburg solve 3D structure of 'nanomachine' that makes tuberculosis virulent

Researchers at CNIO and the University of Würzburg have solved the 3D structure of the T7SS nanomachine used by Mycobacterium tuberculosis to evade the immune system. This finding provides crucial information for developing new therapeutic strategies against tuberculosis, a disease that kills over 1.6 million people worldwide each year.

Melatonin may not help prevent delirium after heart surgery

A recent study published in the Journal of the American Geriatric Society found that melatonin treatment did not reduce the risk of developing delirium following heart surgery. The study included 210 adults and showed a similar proportion of participants experienced severe episodes of delirium in both the melatonin and placebo groups.

Cretan tomb's location may have strengthened territorial claim

A recent study published in Open Archaeology reveals that Tholos A at Apesokari, a Bronze Age circular tomb on Crete, was deliberately placed to control parcels of land and increase visibility from a specific path. The article's use of GIS analysis sheds new light on the role of burial sites and mortuary practices in Prepalatial Crete.
