Indications were respiratory failure (8/16, 50%), severe pulmonary hypertension (5/16, 31%), and cardiopulmonary collapse (3/16, 19%). Four of these patients (27%) also required postoperative support. Six (40%) were

weaned before lung transplant. Six (40%) survived to hospital discharge. Survival to discharge was higher among patients weaned before lung transplant (4/6, 66% vs 2/9, 22%). Twenty-two patients (median age, 9.4 years; range, 0.2-21 years) underwent 24 extracorporeal membrane oxygenation runs after lung transplant. Indications for postoperative support were primary graft dysfunction (18/24, 75%), pneumonia (4/24, 16%), and others (2/24, 9%). Median time between lung transplant and institution of extracorporeal membrane oxygenation was 32 hours (range, 0-1084 hours); median duration find more of support was 141 hours (range, 48-505 hours). Five of these patients (23%) survived to hospital discharge. Among nonsurvivors, causes of death were intractable respiratory failure Blasticidin S (12/17, 70%) and infectious complications (4/17, 24%).

Conclusions: Need for perioperative extracorporeal membrane oxygenation support is associated with significant morbidity and mortality among pediatric patients receiving lung transplants. A subset of patients who can be weaned from support preoperatively have greater likelihood of survival. (J Thorac Cardiovasc Surg 2010; 140: 427-32)”
“It is known that the number of newly generated neurons is increased in the

young and adult rodent subventricular zone (SVZ) and dentate gyrus (DG) after transient brain ischemia. However, it remains unclear whether increase in neurogenesis in the adult DG induced by ischemic stroke is transient or sustained. We here reported that from 2 weeks to 6 months after transient middle cerebral artery occlusion (MCAO), there were more doublecortin positive (DCX+) cells in the ipsilateral compared to the sham-control and contralateral DG of the adult rat. After the S-phase marker 5-bromo-2′-deoxyuridine (BrdU) was injected 2 days after MCAO to label LY294002 newly generated cells, a large number of BrdU-labeled neuroblasts differentiated into mature granular neurons. These BrdU-labeled neurons survived for at least

6 months. When BrdU was injected 6 weeks after injury, there were still more newly generated neuroblasts differentiated into mature neurons in the ipsilateral DG. Altogether, our data indicate that transient brain ischemia initiates a prolonged increase in neurogenesis and promotes the normal development of the newly generated neurons in the adult DG.

“Objective: Owing to the improved long-term outcome after cardiac transplantation, cardiac allograft vasculopathy or valvular disease is developing late after heart transplantation in a growing number of patients. In this study, we evaluated our results of nonretransplant cardiac surgery in these patients and compared them with those after retransplantation.
