ReviewChronic lung allograft dysfunction after lung transplantation: the moving target.
Chronic lung allograft dysfunction is a major challenge in long-term management of lung transplant recipients. Both alloimmune-dependent factors (rejection) and alloimmune-independent factors contribute to the development of chronic lung allograft dysfunction. Thus, use of the term "chronic rejection" tends to be intentionally avoided among specialists in the field, although "chronic rejection" is still an acceptable lay word understood by many patients. ⋯ Until preventive and therapeutic options are refined, chronic lung allograft dysfunction will remain a major life-limiting factor. It has significant psychological, physical, social, and economic impacts. Early introduction of palliative care is another important strategy to improve patients' quality of life.

ReviewPerioperative control of blood glucose level in cardiac surgery.
It is well recognized that poor perioperative blood glucose (BG) control can increase the risk of infection, cardiovascular accidents, and even death in patients undergoing cardiac surgery. Since it has been reported that tight BG control (80-110 mg/dL) yields better outcomes in critically ill patients, it became a standard of care to control BG using intravenous insulin infusion in ICU. However, it has been debated in terms of the optimal target range whether a strict control with intensive insulin therapy is better than liberal control. ⋯ In fact, a meta-analysis of randomized clinical trials concluded that tight BG control was not associated with significantly reduced hospital mortality but was associated with an increased risk of hypoglycemia. According to the current published guidelines, it seems to be optimal to control BG level of 140-180 mg/dL in ICU. In terms of more strict BG control (110-140 mg/dL), it may be appropriate in selected patients as long as this can be achieved without significant hypoglycemia.

Case ReportsAortic arch reconstruction for interrupted aortic arch using an aberrant right subclavian artery.
An aberrant right subclavian artery can be used in a variety of ways in complex aortic arch reconstructions, including reconstruction of an interrupted aortic arch. Here, we described the case of a 4-month-old female infant with a type B interrupted aortic arch, who underwent arch reconstruction using an aberrant right subclavian artery.
