001] blood transfusions were at greater risk for 30-day readmission. Median follow-up period was 4.19 years (2.45 - 6.10). The 30-day readmission cohort had a significantly higher mortality risk during early (6 months) follow-up [HR 2.49 (2.01-3.10); P less then 0.001] and late (60 months) follow-up [HR 1.30 (1.16-1.47); P less then 0.001]. After risk adjustment, the 30-day readmission cohort was significantly associated with increased mortality over the study follow-up period [HR 1.62 (1.48, 1.78); P less then 0.001]. 30-day readmissions were an independent predictor of subsequent long-term hospital readmission [HR 1.61 (1.50, 1.73); P less then 0.001]. Patients who require 30-day readmissions following cardiac surgery are at increased risk of long-term mortality and repeat readmissions. Early postoperative hospital readmission may be a marker for worse long-term outcomes in cardiac surgery.N1-positive (T1-3, N1, M0) non-small cell lung cancer (NSCLC) represents a minority distribution (∼8%) of the approximately 234,000 diagnosed cases per year. As such, there is a paucity of modern high-quality data regarding outcomes following surgically-resected, stage N1-positive NSCLC. Randomized controlled trials from more than a decade ago have demonstrated a modest 5.4% survival benefit with adjuvant chemotherapy but have included heterogenous patient populations and stage distributions. Large database analyses have questioned the role of perioperative chemotherapy in resected patients with N1 disease, but without much granular detail regarding staging, quality of surgery, and chemotherapy. This single-institution study sought to evaluate the role of perioperative chemotherapy, specifically in N1-positive NSCLC patients. Data for all patients with surgically resected N1-positive NSCLC (T1-3, N1, M0) between 2006 and 2016 were collected for this study. Patients who underwent pneumonectomy were excluded frverall survival (22.7%) and disease-free survival (5.6%) than patients with single-station N1 nodal metastasis (60.4% overall survival at 5 years, P = 0.003; 46.0% disease-free survival at 5 years, P less then 0.001). On multivariable analysis, receiving any adjuvant chemotherapy was associated with improved overall survival and disease-free survival (Overall Survival HR 0.47, P less then 0.01 | Disease-Free Survival HR 0.46, P less then 0.01). Multistation N1 disease was associated with significantly worse disease-free survival (HR 2.11, P = 0.04). Perioperative chemotherapy was associated with improved survival in N1-positive NSCLC, and the potential magnitude of benefit exceeded 25% in this study. Patients with single-station N1 lymph node metastasis were observed to have better disease-free survival.It is unclear whether the additional conduit to supplement bilateral internal thoracic arteries (BITA) influences the patient outcome in coronary surgery. This retrospective study compared long-term survival of patients undergoing left-sided BITA grafting in which the third conduit to the right coronary system (RCA) was either vein graft (SVG) or gastroepiploic artery (GEA). From 1989 to 2014, 1432 consecutive patients underwent left-sided revascularization with BITA associated with SVG (n = 599) or GEA (n = 833) to RCA. Propensity score was calculated by logistic regression model and patients were matched 1 to 1 leading to 2 groups of 320 matched patients. The primary end point was the overall mortality from any cause. GEA was used in significantly lower risk patients. The 30-day mortality was 1.6% without influence of the graft configuration. Postoperative follow-up was 13.6 ± 6.6 years and was 94% complete. The significant difference in patients' survival observed at 20 years in favor of GEA in unmatched groups (48 ± 4% vs 33 ± 6%, P less then 0.001) was not confirmed in matched groups (41 ± 7% vs 36 ± 7%, P = 0.112). In multivariable Cox model analysis, the conduit used to RCA did not influence the long-term survival in matched groups, like no other graft configuration or operative parameter. Only complete revascularization remained predictor of survival (P = 0.016), with age (P less then 0.0001), diabetes status (P = 0.007), and left ventricle ejection fraction (P less then 0.0001). Long-term survival in patients undergoing BITA grafting is not affected by using GEA as third arterial conduit in alternative to SVG. Further studies are necessary to assess its impact on long-term cardiac events.This study aimed to evaluate the antimicrobial activity of a new quinolone, lascufloxacin, for the treatment of complicated pneumonia caused by Streptococcus pneumoniae and Prevotella intermedia using a neutropenic mice pneumonia mixed-infection model. In this study, one S. pneumoniae and four P. intermedia isolates were utilized. Antimicrobial efficacy was calculated for each isolate as the reduction of the bacterial count comparatively to the non-treated mice (log10 colony forming units (cfu)/mL) obtained in the lungs of the treated mice after 24 h. Consequently, the bacterial densities of S. pneumoniae (KY-9) and P. intermedia (335) in the lungs of control animals were 8.20 ± 0.19 log10 cfu/mL and 5.26 ± 1.50 log10 cfu/mL, respectively. At human-simulated doses, lascufloxacin and levofloxacin showed high antimicrobial activities against not only S. pneumoniae (lascufloxacin 1.88 ± 0.43 log10 cfu/mL, p less then 0.001; levofloxacin 4.30 ± 0.75 log10 cfu/mL, p less then 0.001), but also P. intermedia (lascufloxacin 1.54 ± 0.57 log10 cfu/mL, p less then 0.001; levofloxacin 2.79 ± 0.55 log10 cfu/mL, p = 0.0102). Additionally, levofloxacin demonstrated attenuated antimicrobial efficacies against S. pneumoniae in the mixed-infection model compared with that in the single infection model. In contrast, lascufloxacin showed enhanced antimicrobial activities against S. pneumoniae and P. intermedia in the mixed-infection model. In conclusion, lascufloxacin resulted in enhanced efficacies against S. pneumoniae and P. intermedia, in both the single and mixed-infection models used. this website These data support the clinical utility of lascufloxacin for use against S. pneumoniae and P. intermedia in the treatment of pneumonia.this website
