Background Coronary artery bypass grafting for acute coronary syndrome complicated by cardiogenic shock ( CS ) is associated with a high mortality. This registry study aimed to distinguish between ...early surgical outcomes of CS patients with non- ST -segment-elevation myocardial infarction ( NSTEMI ) and ST -segment-elevation myocardial infarction ( STEMI ). Methods and Results Patients with NSTEMI (n=1218) or STEMI (n=618) referred for coronary artery bypass grafting were enrolled in a prospective multicenter registry between 2010 and 2017. CS was present in 227 NSTEMI (18.6%) and 243 STEMI patients (39.3%). Key clinical end points were in-hospital mortality ( IHM ) and major adverse cardiocerebral events ( MACCEs ). Predictors for IHM and MACCEs were identified using multivariable logistic regression analysis. STEMI patients with CS were younger, had a lower prevalence of diabetes mellitus and multivessel disease, and exhibited higher myocardial injury (troponin 9±17 versus 3±6 ng/mL) before surgery compared with patients with NSTEMI ( P<0.05). Emergency coronary artery bypass grafting was performed more often in STEMI (58%) versus NSTEMI (40%; P=0.002). On-pump surgery with cardioplegia was the preferred surgical technique in CS . IHM and MACCE rates were 24% and 49% in STEMI patients with CS and were higher compared with NSTEMI ( IHM 15% versus MACCE 34%; P<0.001). Predictors for IHM and MACCE in CS were a reduced ejection fraction and a higher European System for Cardiac Operative Risk Evaluation score. Conclusions Surgical revascularization in NSTEMI and STEMI patients with CS is associated with a substantial but not prohibitive IHM and MACCE rate. Worse early outcomes were found for patients with STEMI complicated by CS compared with NSTEMI patients.
Objectives
Management of acute abdomen (AA) differs due to the heterogeneity of underlying pathophysiology. Complications of AA and its overall outcome after cardiac surgery are known to be ...associated with poor results. The aim of this retrospective analysis was to evaluate risk factors for AA in patients undergoing cardiac surgery.
Methods
Between December 2011 and December 2014, a total of 131 patients with AA after cardiac surgery were identified and retrospectively analyzed using our institutional database. Statistical analysis of risk factors concerning in-hospital mortality of mentioned patient cohort was performed using IBM SPSS Statistics.
Results
Overall in-hospital mortality was 54.2% (71/131). Analyzing in-hospital non-survivors (NS) versus in-hospital survivors (S) peripheral artery disease (28.2% vs. 11.7%;
p
= 0.03), the need for assist device therapy (33.8% vs. 16.7%;
p
= 0.03) and the requirement of hemodialysis (67.6% vs. 23.3%;
p
< 0.01) were significantly higher in NS. Furthermore, lactic acid values at onset of symptoms were shown to be significantly higher in NS (5.7 ± 5.7 mmol/L vs. 2.8 ± 2.9 mmol/L;
p
< 0.01). Assured diagnosis of mesenterial ischemia was strongly associated with worse outcome (odds ratio 10.800, 95% confidence interval 2.003–58.224;
p
= 0.006).
Conclusion
In conclusion, in critically ill patients after performed cardiac surgery peripheral vascular disease, need for supportive hemodynamic assist device systems and occurrence of renal failure are risk factors associated with worsen outcome. Additionally, rise of lactic acid could potentially be associated with onset of intestinal malperfusion and should be taken into account in therapeutic decisions preventing fatal mesenterial ischemia.
Purpose
Preoperative pulmonary function testing is mandatory for non-small cell lung cancer (NSCLC) surgery. The predicted postoperative FEV1 (ppoFEV1) is used for further risk stratification. We ...compared the ppoFEV1 with the postoperative FEV1 (postFEV1) in order to improve the calculation of the ppoFEV1.
Methods
87 patients voluntarily received an FEV1 assessment 1 year after surgery. ppoFEV1 was calculated according to the Brunelli calculation. Baseline characteristics and surgical procedure were compared in a uni- and multivariate analysis between different accuracy levels of the ppoFEV1. Parameters which remained significant in the multinominal regression analysis were evaluated for a modification of the ppoFEV1 calculation.
Results
Independent factors for a more inaccurate ppoFEV1 were preoperative active smoking (odds ratio (OR) 4.1, confidence interval (CI) 3.6–6.41;
p
= 0.01), packyears (OR 4.1, CI 3.6–6.41;
p
= 0.008), younger age (OR 1.1, CI 1.01–1.12;
p
= 0.03), and patients undergoing pneumectomy (OR 5.55, CI 1.35–23.6;
p
= 0.01). For the customized ppoFEV1 we excluded pneumonectomies. For patients < 60 years, an additional lung segment was added to the calculation. ppoFEV1 = preFEV1 ×

Conclusion
We were able to enhance the predictability of the ppoFEV1 with modifications. The modified ppoFEV1 (1.828 l ± 0.479 l) closely approximates the postFEV1 of 1.823 l ± 0.476 l, (0.27%) while the original ppoFEV1 calculation is at 1.78 l ± 0.53 (2.19%). However, if patients require pneumectomy, more complex techniques to determine the ppoFEV1 should be included to stratify risk.

Zusammenfassung
Die optimale chirurgische Versorgung posttraumatischer, onkologischer oder angeborener Thoraxwanddefekte beeinflusst die Genesung der Patienten deutlich. Unabhängig von der Ätiologie ...haben eine verschlechterte Atemphysiologie bei instabilem Thorax oder eine verminderte pulmonale Clearance vergesellschaftet mit akuten und chronischen pulmonalen Infekten einen Einfluss auf den Krankheitsverlauf der betroffenen Patienten. Das postoperative Auftreten eines intrathorakalen Totraums kann zu einem schwer behandelbaren Empyem führen. Jeder Thoraxwanddefekt muss nach Größe, Tiefe und Lokalisation am Brustkorb genau beurteilt und behandelt werden. Die Komplexität dieses Krankheitsbildes und die daraus resultierenden Komplikationen erfordern höchste chirurgische Sorgfalt sowie eine perioperative intensive interdisziplinäre Betreuung.
