Does haptoglobin 2-1 phenotype predict rapid growth of abdominal aortic aneurysms?
The Hp 2-1 phenotype showed a strong association with increased rates of the expansion of AAAs and may be a useful independent predictor of growth rate. Further large follow-up studies will be needed to investigate the pathomechanisms of association and the role of elastase and inflammation in the progression of AAA.
This geographic study suggests that low sunlight exposure is associated with an increased incidence of Crohn's disease. Further studies are needed to determine if this association is causal.
