Transesophageal echocardiography guided cannulation for peripheral cardiopulmonary bypass during robotic cardiac surgery.
Minimally invasive cardiac surgery and closed chest cardiopulmonary bypass (CPB) techniques continue to evolve. Previous reports have demonstrated the benefits of fluoroscopy guided cannulation for endovascular CPB during port access cardiac surgery. However, few data are available on the role of transesophageal echocardiography (TEE) guided cannulation for peripheral CPB during robotic cardiac surgery. The purpose of this study was to evaluate TEE guided cannulation for peripheral CPB during robotic cardiac surgery. ⋯ TEE may be useful in guiding successful placement of the cannulae in the IVC, SVC, and AAO in the establishment of peripheral CPB during robotic cardiac surgery.

Correlation of eosinophil counts in induced sputum and fractional concentration of exhaled nitric oxide and lung functions in patients with mild to moderate asthma.
The airway inflammation could be assessed by some noninvasive approaches. To investigate the value of eosinophil counts in induced sputum and fractional concentration of exhaled nitric oxide (FENO) for the regimen adjustment in patients with asthma, the correlation was analyzed between the two parameters and lung function parameter (forced expiratory volume in one second (FEV(1))). ⋯ Eosinophil counts in induced sputum and FENO are sensitive parameters to detect airway inflammation and may be useful in evaluating the efficacy of treatment and adjusting medication regimens.

Thioredoxin and impaired spatial learning and memory in the rats exposed to intermittent hypoxia.
Obstructive sleep apnea (OSA) can cause cognitive dysfunction and may be a reversible cause of cognitive loss in patients with Alzheimer's disease (AD). Chronic exposure to intermittent hypoxia (IH), such as encountered in OSA, is marked by neurodegenerative changes in rat brain. We investigated the change of thioredoxin (Trx), spatial learning and memory in rats exposed to chronic intermittent hypoxia (CIH). ⋯ The Trx deficit likely plays an important role in the impaired spatial learning and memory in the rats exposed to CIH and may work through the apoptosis of neurons in the hippocampus.
