We sought to investigate the relationship between newly identified genetic variants and vitamin D levels and fracture risk in healthy African American (black) children. This case-control study included children of both sexes, ages 5 to 9 years, with and without forearm fractures. Serum 25-hydroxy vitamin D levels, bone mineral density, body mass index, and calcium/vitamin D intake were measured in 130 individuals (n = 60 cases and n = 70 controls). ⋯ None of the SNPs were associated with fracture status in young blacks. These results suggest that the variants tested, which are associated with circulating vitamin D levels in whites, are not associated with fracture status in healthy black children. Additional research is required to discover the genetics of fracture risk in blacks.

This review arose from a talk entitled "Identifying Targets" and given by the author at EB2011 at the invitation of the American Federation for Medical Research (AFMR). The presentation was part of the American Federation for Medical Research workshop entitled "Keys for Translation: Science and Strategy" and focused on identifying clinically relevant targets as a result of observations made during basic scientific studies. ⋯ Using one line of investigator-initiated research from his own laboratory as an example, the author emphasizes that basic discovery must be hypothesis driven and allowed to follow its logical sequence. Finding treatments, while always an aim of biomedical research, may arise as a result of basic studies that were not originally aimed at a target of translational research.

To examine the performance of hemoglobin A1c (HbA1c) in diagnosing prediabetes and whether it was associated with cardiometabolic risk factors in Chinese adolescents without known diabetes. ⋯ There is poor agreement between HbA1c and FPG or OGTT in diagnosing prediabetes, but the former was associated with the presence of multiple cardiometabolic risk factors in Chinese adolescents.
