Burden of pulmonary arterial hypertension in England: retrospective HES database analysis.

Background: The clinical and economic burden of pulmonary arterial hypertension (PAH) is poorly understood outside the United States. This retrospective database study describes the characteristics of patients with PAH in England, including their healthcare resource utilisation (HCRU) and associated costs.

Methods: Data from 1 April 2012 to 31 March 2018 were obtained from the National Health Service (NHS) Digital Hospital Episode Statistics database, which provides full coverage of patient events occurring in NHS England hospitals.

In Vivo Assays for Assessing the Role of the Wilms' Tumor Suppressor 1 (Wt1) in Angiogenesis.

The Wilms' tumor suppressor gene (WT1) is widely expressed during neovascularization, but it is almost entirely absent in quiescent adult vasculature. However, in vessels undergoing angiogenesis, WT1 is dramatically upregulated. Studies have shown Wt1 has a role in both tumor and ischemic angiogenesis, but the mechanism of Wt1 action in angiogenic tissue remains to be elucidated.
