Effects of changes in end-tidal carbon dioxide tension on oral tissue blood flow and tissue oxygen tension during remifentanil infusion in rabbits.
The aim of this study was to investigate the effects of end-tidal carbon dioxide tension (ETCO2) changes during remifentanil infusion on mandibular bone marrow tissue blood flow (BBF), masseter muscle tissue blood flow (MBF), mandibular bone marrow tissue oxygen tension (PbO2) and masseter muscle tissue oxygen tension (PmO2) in rabbits. ⋯ PbO2 and PmO2 remained unchanged despite changes in BBF and MBF during ETCO2 change with or without remifentanil infusion.

Prevalence of undernutrition in surgical patients and the effect on length of hospital stay.
Low nutritional status is common among surgical patients. A low nutrition profile is related to muscle weakness and immune suppression, which may be associated with negative outcomes. In this study, we evaluated the prevalence of low nutrition and assessed the relationship between nutritional status and length of hospital stay in surgical patients. ⋯ Our results suggest that a low nutrition profile before surgery is associated with a prolonged hospital stay.

Clinical features and significance of leukopenia occurring immediately after endovascular surgery.
Inflammation after stent graft surgery is known as postimplantation syndrome (PIS) and it causes leukocytosis. However, we have experienced leukopenia in the very early postoperative phase of endovascular surgery at our institution. We investigated leukopenia, an under-recognized phenomenon that occurred after transcatheter aortic valve implantation (TAVI), endovascular aortic repair (EVAR), and thoracic endovascular aortic repair (TEVAR). ⋯ Leukopenia was a common phenomenon immediately after endovascular surgery, especially TAVI. It resolved a day after surgery and was not associated with PIS or infectious complications. Therefore, it seems to be a transient abnormal hematological finding and a self-limiting condition.
