In 2005, an outbreak of measles occurred that was traced to a student who had returned home to Indiana from a trip to Romania. At a gathering attended by the student, there were an estimated 50 people who lacked evidence of measles immunity, of whom 16 (32 percent) acquired measles. One health care worker also became infected, and severe respiratory distress developed, requiring ventilator support.

In this study, mutations in the gene encoding the sulfonylurea receptor, a component of the beta-cell ATP-sensitive potassium channel, are described in infants with neonatal diabetes. Some of these infants were successfully weaned from insulin by treatment with sulfonylureas.

The beta-cell ATP-sensitive potassium channel is made up of two subunits — SUR1 and Kir6.2 — and its normal function is critical to insulin secretion. This study shows that in 44 of 49 patients with diabetes caused by Kir6.2 mutations, treatment was successfully switched from subcutaneous injection of insulin to oral sulfonylureas.

A clinical prediction rule for the termination of resuscitation during out-of-hospital cardiac arrest was validated in a study of 1240 patients treated by emergency medical technicians (EMTs) trained to use defibrillation. In arrests not witnessed by EMTs, there was no return of spontaneous circulation, no countershocks were administered, and the survival rate was 0.5 percent.
