Multicenter Study Comparative Study Observational StudyLong-term durability of bioprosthetic valves in pulmonary position: Pericardial versus porcine valves.
The long-term durability of the 2 most commonly used types of bioprosthetic valves in the pulmonic position, the porcine and pericardial valves, is unclear. We compared the long-term durability of the pericardial (Carpentier-Edwards PERIMOUNT [CE]) and porcine (Hancock II) valves in the pulmonic position in patients with congenital cardiac anomalies. ⋯ Compared with the pericardial valve, the porcine valve had long-term advantages in terms of reduced reoperation rate and prosthetic valve dysfunction in the pulmonic position in patients with congenital cardiac anomalies.

Comparative StudyClamping versus nonclamping thoracoscopic box ablation in long-standing persistent atrial fibrillation.
To compare clinical outcomes of clamping devices and linear nonclamping devices for isolation of the posterior left atrium (box) in thoracoscopic ablation of long-standing persistent atrial fibrillation. ⋯ Thoracoscopic pulmonary vein and box isolation are highly effective in restoring sinus rhythm in long-standing persistent atrial fibrillation on short-term follow-up. Comparison of clamping and nonclamping devices revealed lower rates of intraoperative exit block of the box in the nonclamping group. However, this did not translate into a significant difference in atrial fibrillation freedom at short-term (1-year) follow-up.

Benefits of progesterone on brain immaturity and white matter injury induced by chronic hypoxia in neonatal rats.
This study aims to evaluate the protective effects of progesterone on white matter injury and brain immaturity in neonatal rats with chronic hypoxia. ⋯ Progesterone could prevent white matter injury and improve brain maturation in a neonatal hypoxic rat model; this may be associated with inducing a switch from M1 to M2 in microglia.
