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.

Observational StudyBody mass index as a tool for optimizing surgical care in coronary artery bypass grafting through understanding risks of specific complications.
To investigate the relationship between body mass index (BMI) and early outcomes, and specific types of morbidities associated with low and high BMI, in patients undergoing coronary artery bypass grafting. ⋯ In patients undergoing coronary artery bypass grafting, low and high BMI were risk factors of mortality associated with different types of morbidities, which may warrant tailored preventive approaches.

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.
