Health Research: Viral infection history in a single drop of blood ♦ How salmonella synchronizes its invasion plan ♦ Developing delirium in ICU linked to fatal outcomes

Viral infection history in a single drop of blood New technology makes it possible to test for current and past infections with any known human virus by analyzing a single drop of a person's blood. The method, called VirScan, is an efficient alternative to existing diagnostics that test for specific viruses one at a time
Study maps types of physical activity associated with better sleep Physical activities, such as walking, as well as aerobics/calisthenics, running, weight-lifting, and yoga/Pilates are associated with better sleep habits, compared to no activity, according to a new study. In contrast, the study shows that other types of physical activity -- such as household and childcare -- work are associated with increased cases of poor sleep habits.
Withholding angiotensin receptor blockers after surgery increases risk of postoperative death Withholding angiotensin receptor blockers for longer than two days after surgery is associated with a significantly increased risk of postoperative death.
How salmonella synchronizes its invasion plan A new study has uncovered a mechanism by which Salmonella bacteria organize the expression of genes required for infection. Salmonella bacteria are one of the leading causes of foodborne illness. Part of what makes them so successful is their ability to invade our bodies, overcoming our natural defenses. Understanding how they do this could lead to new ways of preventing their invasion.
Developing delirium in ICU linked to fatal outcomes About one-third of patients admitted to an intensive care unit (ICU) will develop delirium, a condition that lengthens hospital stays and substantially increases one’s risk of dying in the hospital.
