Surgical treatment for non-small cell lung cancer in octogenarians--the usefulness of video-assisted thoracic surgery.
The purpose of this study was to investigate whether surgical treatment for non-small cell lung cancer (NSCLC) confers a survival benefit in octogenarians, and whether video-assisted thoracic surgery (VATS) is effective in terms of postoperative morbidity, mortality, and quality of life (QOL). Among 1684 patients with primary NSCLC who underwent pathologically complete resection, 95 were octogenarians. Operation was performed by the VATS approach (VATS group, n=58) or the standard thoracotomy (ST group, n=37). ⋯ There was no significant difference in overall 5-year survival rates between the ST group and the VATS group (P=0.144). The VATS approach for pulmonary resection is recommended for octogenarians with NSCLC. Surgical resection is the optimal treatment for stage IA NSCLC, and therefore, advanced age is not a contraindication for curative resection.

Prophylactic intra-aortic balloon pump in high-risk patients undergoing coronary artery bypass grafting: a propensity score analysis.
The optimal use of prophylactic intra-aortic balloon pump (IABP) to prevent postcardiotomy low cardiac output syndrome (LCOS) is still debated and poorly defined. The aim of this study was to evaluate whether prophylactic IABP reduces the rate of postcardiotomy LCOS and improves the early outcome in hemodynamically stable, high-risk patients undergoing coronary artery bypass grafting (CABG). From May 2004 to August 2007, 141 consecutive risk patients underwent CABG. ⋯ Prophylactic IABP patients were more likely to be younger (P<0.0001), had a recent myocardial infarction (P<0.0001), lower ejection fraction (P=0.006), and higher New York Heart Association (NYHA) functional class (P=0.05). After risk-adjusting for propensity score, prophylactic IABP patients had a lower incidence of postcardiotomy LCOS (adjusted OR 0.07, P=0.006), postoperative myocardial infarction (adjusted OR 0.04, P=0.04), a shorter length of hospital stay (10.4+/-0.8 vs. 12.2+/-0.6 days, P<0.0001) than those who did not receive IABP. This study shows that prophylactic IABP treatment for hemodynamically stable high-risk patients undergoing CABG may improve postoperative course reducing postcardiotomy LCOS, postoperative myocardial infarction and length of hospital stay.

Aprotinin reduces the antiplatelet effect of clopidogrel.
Aprotinin reduces bleeding and transfusion rates in patients undergoing coronary surgery while on clopidogrel. However, safety studies have indicated that aprotinin may have a possible adverse effect related to an increased incidence of thromboembolic events. We therefore studied the adenosinediphosphate (ADP) mediated platelet aggregation before and after administration of aprotinin in patients on clopidogrel. ⋯ Clopidogrel non-responders with >90% aggregation (n=4) had a median aggregation of 94.5% (91.5/97.5) vs. 82% (73/87, P<0.01) in the responders (n=11). The median increase in platelet aggregation after aprotinin was 8% (5/20) in the responders vs. 0% (-5.25/3, P<0.01) in the non-responders. Aprotinin increased ADP induced platelet aggregation from 84 to 94% in patients on clopidogrel, which corresponds to a median decrease in relative platelet inhibition of >50%.
