Practical chart for health practitioners to use to assess newborn size (weight, length, head circumference) at birth against global standards. This version of the chart is being piloted within the University of Oxford hospital network, and plans to pilot in the INTERGROWTH-21st study sites and in Boston area hospitals are developing quickly. Practitioners can download and use this version of the chart freely. To connect with the INTERGROWTH-21st team regarding your experience with piloting this chart, or to request modifications to the chart (e.g. language; different institutional logo), please contact intergrowth21st@tghn.org.

The last decade has witnessed a substantial increase of multi-centre, public health-oriented clinical trials in poor countries. However, non-commercial research groups have less staff and financial resources than traditional commercial sponsors, so the trial teams have to be creative to comply with Good Clinical Practices (GCP) requirements. This article hopes to feed the reflection on the methodological and ethical aspects of clinical trials carried out in developing countries by North-South collaborative research groups.

This paper, recently published on the Italian Journal of Tropical Medicine(Vol 15, N 1-4, 2010), reports on a debate that took place during the 6thEuropean Conference of Tropical Medicine in 2009, on some topics of greatinterest for GlobalHealthTrials.org: is there a global standard for clinicalresearch? Should standards be adapted in developing countries? How toencourage research while preventing the exploitation of vulnerableindividuals or groups? Five "debate questions" where addressed by ProfessorNick White and by Dr. Lumuli Mbonile, and discussed with the moderator(Raffaella Ravinetto) and the audience.
