CONTEXT In randomized controlled trials (RCTs), some drugs, including CB1 antagonists for obesity treatment, have been shown to cause increased suicidal ideation. A key question is whether drugs that increase or are associated with increased suicidal ideations are also associated with suicidal behavior, or whether drug-induced suicidal ideations are unlinked epiphenomena that do not presage the...

Graft-vs-host disease is still the leading cause of morbidity and mortality in patients undergoing bone marrow transplantation. It is important to start treatment early to reduce the severity and consequences of this complication. Cutaneous lesions are often the presenting compliant of graft-vs-host disease and presage visceral involvement. We present the case of a 45-year-old woman with multip...

Children differ in how quickly they reach linguistic milestones. Boys typically produce their first multi-word sentences later than girls do. We ask here whether there are sex differences in children's gestures that precede, and presage, these sex differences in speech. To explore this question, we observed 22 girls and 18 boys every 4 months as they progressed from one-word speech to multi-wor...

In human infants, perception–action routines that combine objects and surfaces in playful exploration presage using objects as tools. Banging a surface with a held object is a canonical example of this phenomenon. This longitudinal study revealed when and how exploratory activity with an object emerges in chimpanzees. We studied the development of exploratory actions with objects and surfaces i...
