NIHR Signal People maintain increases in physical activity three years after receiving pedometers

Middle-aged to older adults given pedometers and a walking programme as part of two NIHR trials continued to be active three years later. In one trial they were walking around 650 extra steps a day. In both trials, they spent about 30 minutes per week extra in moderate-to-vigorous physical activity compared to controls.

NIHR Signal Cell salvage during caesarean section doesn’t reduce blood transfusions

In a large UK trial, cell salvage for women at risk of blood loss during caesarean did not reduce the need for donor blood transfusion, though few needed transfusion (2.5% compared with 3.5% among controls).

More babies are being born by caesarean section and if blood loss is excessive, transfusions may be required, probably by about one in 20... Read More
