Born too soon: global epidemiology of preterm birth and drivers for change.

Progress: There has been no measurable change in global preterm birth rates in the past decade, in any region. A handful of countries have reduced their preterm birth rates, but only marginally (0.5 percentage points annually), and there has been little progress in availability of preterm birth data globally.

Fatal outcome from meningococcal disease--an association with meningococcal phenotype but not with reduced susceptibility to benzylpenicillin.

Penicillin has been the mainstay of treatment for meningococcal disease. Isolates of Neisseria meningitidis that are less susceptible to penicillin have been reported in several countries and in recent years have become more common. The clinical significance of this reduced susceptibility has not been investigated on a large scale.
