At what point does a stressor end or begin? Every 45 minutes over the course of five days, the eWatch will prompt wearers to take part in a 2-to-3-minute interview. Previous research has shown that responses to such interviews help predict who will show higher rates of plaque development in the arteries, a risk factor for heart attack or stroke. Using interviews in real time allows researchers to quantify how stressors impact one’s daily life, as well as to pinpoint when these results begin so when they end. Usage of the eWatch technology should help researchers in finding the optimal way for responding to such interviews during daily activities, whether by pressing a switch, moving the wrist or speaking right into a wireless hearing bug gadget.University of Maryland School of Medication researcher Christopher Plowe, M.D., MPH, was the co-leader of the scholarly research. The trial enrolled volunteers surviving in Bandiagara, a rural town in northeast Mali with a heavy burden of malaria. In this relatively dry region, minimal new infections occur during the driest month of the entire year, March, but people typically get up to 60 malaria-transmitting mosquito bites per month in August and September, when the rainy time of year peaks. A complete of 60 participants were assigned randomly to receive either a full or half-dose of the candidate malaria vaccine or an authorized rabies vaccine, which offered as a control.
