RESUMEN
BACKGROUND: Cardiac arrest is associated with high mortality rates and severe neurological impairments. One of the underlying mechanisms is global ischemia-reperfusion injury of the body, particularly the brain. Strategies to mitigate this may thus improve favorable neurological outcomes. The use of extracorporeal cardiopulmonary membrane oxygenation (ECMO) during CA has been shown to improve survival, but available systems are vastly unable to deliver goal-oriented resuscitation to control patient's individual physical and chemical needs during reperfusion. Recently, controlled automated reperfusion of the whoLe body (CARL), a pulsatile ECMO with arterial blood-gas analysis, has been introduced to deliver goal-directed reperfusion therapy during the post-arrest phase. METHODS: This review focuses on the device profile and use of CARL. Specifically, we reviewed the published literature to summarize data regarding its technical features and potential benefits in ECPR. RESULTS: Peri-arrest, mitigating severe IRI with ECMO, might be the next step toward augmenting survival rates and neurological recovery. To this end, CARL is a promising extracorporeal oxygenation device that improves the early reperfusion phase after resuscitation.
RESUMEN
OBJECTIVES: To evaluate the association between guideline-conforming as compared to shorter than recommended withdrawal period of P2Y12 receptor inhibitors prior to isolated on-pump coronary artery bypass grafting (CABG) and the incidence of severe bleeding and ischaemic events. Randomized controlled trials are lacking in this field. METHODS: We searched PUBMED, Embase and other suitable databases for studies including patients on P2Y12 receptor inhibitors undergoing isolated CABG and reporting bleeding and postoperative ischaemic events from 2013 to March 2024. The primary outcome was incidence of Bleeding Academic Research Consortium type 4 (BARC-4) bleeding defined as any of the following: perioperative intracranial bleeding, reoperation for bleeding, transfusion of ≥5 units of red blood cells, chest tube output of ≥2 l. The secondary outcome was postoperative ischaemic events according to the Academic Research Consortium 2 Consensus Document. Patient-level data provided by each observational trial were synthesized into a single dataset and analysed using a 2-stage IPD-MA. RESULTS: Individual data of 4837 patients from 7 observational studies were synthesized. BARC-4 bleeding, 30-day mortality and postoperative ischaemic events occurred in 20%, 2.6% and 5.2% of patients. After adjusting for EuroSCORE II and cardiopulmonary bypass time, guideline-conforming withdrawal was associated with decreased BARC-4 bleeding risk in patients on clopidogrel [adjusted odds ratio (OR) 0.48; 95% confidence intervals (CI) 0.28-0.81; P = 0.006] and a trend towards decreased risk in patients on ticagrelor (adjusted OR 0.48; 95% CI 0.22-1.05; P = 0.067). Guideline-conforming withdrawal was not significantly associated with 30-day mortality risk (clopidogrel: adjusted OR 0.70; 95% CI 0.30-1.61; ticagrelor: adjusted OR 0.89; 95% CI 0.37-2.18) but with decreased risk of postoperative ischaemic events in patients on clopidogrel (clopidogrel: adjusted OR 0.50; 95% CI 0.30-0.82; ticagrelor: adjusted OR 0.78; 95% CI 0.45-1.37). BARC-4 bleeding was associated with 30-day mortality risk (adjusted OR 4.76; 95% CI 2.67-8.47; P < 0.001). CONCLUSIONS: Guideline-conforming preoperative withdrawal of ticagrelor and clopidogrel was associated with a 50% reduced BARC-4 bleeding risk when corrected for EuroSCORE II and cardiopulmonary bypass time but was not associated with increased risk of 30-day mortality or postoperative ischaemic events.

Background: The most effective method and length of time for administering adjuvant immunotherapy after surgery for non-small cell lung cancer (NSCLC) are still unknown. Various clinical trials have utilized diverse strategies for adjuvant treatment. In this case, we explore the potential benefits of neoadjuvant immunotherapy combined with chemotherapy in managing locally advanced lung squamous carcinoma, which often poses challenges for treatment. This multimodal approach aims to downstage tumors and optimize surgical outcomes. Case Description: Following a diagnosis of stage IIIB lung cancer, the patient underwent three cycles of neoadjuvant therapy using sintilimab, Abraxane, and Lobaplatin, resulting in a significant 45% reduction in tumor size. Subsequently, a right lower lobe lobectomy and systematic lymphadenectomy were performed using a uniportal video-assisted thoracic surgery (VATS) approach. Postoperative analysis revealed negative lymph nodes, with only a 5-mm residual tumor in the tumor bed, downstaging the cancer to IA1. Remarkably, the patient experienced a smooth recovery without any postoperative complications. One cycle of adjuvant therapy was administered following the operation to further support the patient's recovery and minimize the risk of disease recurrence. This comprehensive treatment approach underscores the importance of neoadjuvant therapy in optimizing surgical outcomes and improving long-term prognosis for patients with locally advanced lung cancer. Conclusions: For patients with stage III locally advanced lung squamous carcinoma, the combination of Sintilimab and Platinum-based drugs can be used as a neoadjuvant therapy which can reduce the difficulty of the operation.
RESUMEN
INTRODUCTION: Despite clear guideline recommendations, surgery is not consistently carried out as part of multimodal therapy in stage I small cell lung cancer (SCLC) patients. The role of surgery in stages II and III is even more controversial. In the absence of current randomized control trials (RCT), we performed a meta-analysis comparing surgery versus non-surgical treatment in stage I to III SCLC patients. METHODS: A systematic review of the literature was conducted on 1 July 2023, focusing on studies pertaining to the impact of surgery on small cell lung cancer (SCLC). These studies were evaluated using the ROBINS-I tool. Statistical analyses, including I² tests, Q-statistics, DerSimonian-Laird tests, and Egger regression, were performed to assess the data. In addition, 5-year survival rates were analyzed. The meta-analysis was conducted according to PRISMA standards. RESULTS: Among the 6826 records identified, 10 original studies encompassing a collective cohort of 95,323 patients were incorporated into this meta-analysis. Heterogeneity was observed across the included studies, with no discernible indication of publication bias. Analysis of patient characteristics revealed no significant differences between the two groups (p-value > 0.05). The 5-year survival rates in a combined analysis of patients in stages I-III were 39.6 ± 15.3% for the 'surgery group' and 16.7 ± 12.7% for the 'non-surgery group' (p-value < 0.0001). SCLC patients in stages II and III treated outside the guideline with surgery had a significantly better 5-year survival compared to non-surgery controls (36.3 ± 20.2% vs. 20.2 ± 17.0%; p-value = 0.043). CONCLUSIONS: In the absence of current RCTs, this meta-analysis provides robust suggestions that surgery might significantly improve survival in all SCLC stages. Non-surgical therapy could lead to a shortening of life. The feasibility of surgery in non-metastatic SCLC should always be evaluated as part of a multimodal treatment.
RESUMEN
Objectives: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used due to its beneficial outcomes and results compared to conventional CPR. Cardiac arrests can be categorized depending on location: in-hospital cardiac arrest (IHCA) and out-of-hospital cardiac arrest (OHCA). Despite this distinction, studies comparing the two are scarce, especially in comparing outcomes after ECPR. This study compared patient characteristics, cardiac arrest characteristics, and outcomes. Methods: Between 2016 and 2022, patients who underwent ECPR for cardiac arrest at our institution were retrospectively analyzed, depending on the arrest location: IHCA and OHCA. We compared periprocedural characteristics and used multinomial regression analysis to indicate parameters contributing to a favorable outcome. Results: A total of n = 157 patients (100%) were analyzed (OHCA = 91; IHCA = 66). Upon admission, OHCA patients were younger (53.2 ± 12.4 vs. 59.2 ± 12.6 years) and predominantly male (91.1% vs. 66.7%, p=<0.001). The low-flow time was significantly shorter in IHCA patients (41.1 ± 27.4 mins) compared to OHCA (63.6 ± 25.1 mins). Despite this significant difference, in-hospital mortality was not significantly different in both groups (IHCA = 72.7% vs. OHCA = 76.9%, p = 0.31). Both groups' survival-to-discharge factors were CPR duration, low flow time, and lactate values upon ECMO initiation. Conclusion: Survival-to-discharge for ECPR in IHCA and OHCA was around 25%, and there was no statistically significant difference between the two cohorts. Factors predicting survival were lower lactate levels before cannulation and lower low-flow time. As such, OHCA patients seem to tolerate longer low-flow times and thus metabolic impairments compared to IHCA patients and may be considered for ECMO cannulation on a broader time span than IHCA.
RESUMEN
OBJECTIVES: Classifying radiologic pulmonary lesions as malignant is challenging. Scoring systems like the Mayo model lack precision in predicting the probability of malignancy. We developed the logistic scoring system 'LIONS PREY' (Lung lesION Score PREdicts malignancY), which is superior to existing models in its precision in determining the likelihood of malignancy. METHODS: We evaluated all patients that were presented to our multidisciplinary team between January 2013 and December 2020. Availability of pathological results after resection or CT-/EBUS-guided sampling was mandatory for study inclusion. Two groups were formed: Group A (malignant nodule; n = 238) and Group B (benign nodule; n = 148). Initially, 22 potential score parameters were derived from the patients' medical histories. RESULTS: After uni- and multivariate analysis, we identified the following eight parameters that were integrated into a scoring system: (1) age (Group A: 64.5 ± 10.2 years vs. Group B: 61.6 ± 13.8 years; multivariate p-value: 0.054); (2) nodule size (21.8 ± 7.5 mm vs. 18.3 ± 7.9 mm; p = 0.051); (3) spiculation (73.1% vs. 41.9%; p = 0.024); (4) solidity (84.9% vs. 62.8%; p = 0.004); (5) size dynamics (6.4 ± 7.7 mm/3 months vs. 0.2 ± 0.9 mm/3 months; p < 0.0001); (6) smoking history (92.0% vs. 43.9%; p < 0.0001); (7) pack years (35.1 ± 19.1 vs. 21.3 ± 18.8; p = 0.079); and (8) cancer history (34.9% vs. 24.3%; p = 0.052). Our model demonstrated superior precision to that of the Mayo score (p = 0.013) with an overall correct classification of 96.0%, a calibration (observed/expected-ratio) of 1.1, and a discrimination (ROC analysis) of AUC (95% CI) 0.94 (0.92-0.97). CONCLUSIONS: Focusing on essential parameters, LIONS PREY can be easily and reproducibly applied based on computed tomography (CT) scans. Multidisciplinary team members could use it to facilitate decision making. Patients may find it easier to consent to surgery knowing the likelihood of pulmonary malignancy. The LIONS PREY app is available for free on Android and iOS devices.
RESUMEN
OBJECTIVES: About 90% of all non-small cell lung cancer (NSCLC) cases are associated with inhalative tabacco smoking. Half of patients continue smoking during lung cancer therapy. We examined the effects of postoperative smoking cessation on lung function, quality of life (QOL) and long-term survival. MATERIALS AND METHODS: In total, 641 patients, who underwent lobectomy between 2012 and 2019, were identified from our single institutional data base. Postoperatively, patients that actively smoked at the time of operation were offered a structured 'smoking cessation' program. For this retrospective analysis, two patient groups (total n = 90) were selected by pair matching. Group A (n = 60) had no postoperative tobacco smoking. Group B (n = 30) involved postoperative continued smoking. Lung function (FEV1, DLCO) and QOL ('SF-36' questionnaire) were measured 12 months postoperatively. We compared long-term outcomes using Kaplan-Meier curves. RESULTS: The mean age in group A was 62.6 ± 12.5 years and that in group B was 64.3 ± 9.7 years (p = 0.82); 64% and 62%, respectively, were male (p = 0.46). Preoperative smoking habits were similar ('pack years': group A, 47 ± 31; group B, 49 ± 27; p = 0.87). All relevant baseline characteristics we collected were similar (p > 0.05). One year after lobectomy, FEV1 was reduced by 15% in both groups (p = 0.98). Smoking cessation was significantly associated with improved DLCO (group A: 11 ± 16%; group B: -5 ± 14%; p <0.001) and QOL (vitality (VT): +10 vs. -10, p = 0.017; physical role function (RP): +8 vs. -17, p = 0.012; general health perceptions (GH): +12 vs. -5, p = 0.024). Patients who stopped smoking postoperatively had a significantly superior overall survival (median survival: 89.8 ± 6.8 [95% CI: 76.6-103.1] months vs. 73.9 ± 3.6 [95% CI: 66.9-80.9] months, p = 0.034; 3-year OS rate: 96.2% vs. 81.0%, p = 0.02; 5-year OS rate: 80.0% vs. 64.0%, p = 0.016). The hazard ratio (HR) was 2.31 [95% CI: 1.04-5.13] for postoperative smoking versus tobacco cessation. CONCLUSION: Postoperative smoking cessation is associated with improved quality of life and lung function testing. Notably, a significant increase in long-term survival rates among non-smoking NSCLC patients was observed. These findings could serve as motivation for patients to successfully complete a non-smoking program.
RESUMEN
OBJECTIVES: Thyroid transcription factor 1 (TTF-1) is a well-established independent prognostic factor in lung adenocarcinoma (LUAD), irrespective of stage. This study aims to determine if TTF-1's prognostic impact is solely based on histomorphological differentiation (tumor grading) or if it independently relates to a biologically more aggressive phenotype. We analyzed a large bi-centric LUAD cohort to accurately assess TTF-1's prognostic value in relation to tumor grade. PATIENTS AND METHODS: We studied 447 patients with resected LUAD from major German lung cancer centers (Berlin and Cologne), correlating TTF-1 status and grading with clinical, pathologic, and molecular data, alongside patient outcomes. TTF-1's impact was evaluated through univariate and multivariate Cox regression. Causal graph analysis was used to identify and account for potential confounders, improving the statistical estimation of TTF-1's predictive power for clinical outcomes. RESULTS: Univariate analysis revealed TTF-1 positivity associated with significantly longer disease-free survival (DFS) (median log HR -0.83; p = 0.018). Higher tumor grade showed a non-significant association with shorter DFS (median log HR 0.30; p = 0,62 for G1 to G2 and 0.68; p = 0,34 for G2 to G3). In multivariate analysis, TTF-1 positivity resulted in a significantly longer DFS (median log HR -0.65; p = 0.05) independent of all other parameters, including grading. Adjusting for potential confounders as indicated by the causal graph confirmed the superiority of TTF-1 over tumor grading in prognostics power. CONCLUSIONS: TTF-1 status predicts relapse and survival in LUAD independently of tumor grading. The prognostic power of tumor grading is limited to TTF-1-positive patients, and the effect size of TTF-1 surpasses that of tumor grading. We recommend including TTF1 status as a prognostic factor in the diagnostic guidelines of LUAD.

Background: Pulmonary capillary wedge pressure (PCWP) is often used as a surrogate for left-ventricular end-diastolic pressure in patients (LVEDP) who are on veno-arterial extracorporeal membrane oxygenation (V-A ECMO) support for cardiogenic shock and cardiac arrest. However, the correlation between PCWP and LVEDP is not clear in the setting of V-A ECMO usage. We sought to evaluate this correlation in this case series. Methods: Patients were referred to our cardiac catheterization laboratory for invasive hemodynamic studies to assess their readiness for VA-ECMO decannulation. All patients underwent simultaneous left and right heart catheterization. Using standard techniques, we measured PCWP and LVEDP simultaneously. Continuous variables were reported as medians with interquartile ranges. The correlation between PCWP and LVEDP was evaluated using simple linear regression and reported as R2. Results: Four patients underwent invasive hemodynamic studies 4 (2.5, 7) days after VA-ECMO cannulation. All four patients had suffered in-hospital cardiac arrest and had been put on VA-ECMO. At the baseline level of VA-ECMO flow of 4.1 (3.8, 4.4) L/min, the median LVEDP and PCWP were 6 (4, 7.5) mmHg and 12 (6.5, 16) mmHg, respectively. At the lowest level of VA-ECMO flow of 1.9 (1.6, 2.0) L/min, the median LVEDP and PCWP was 13.5 (8.5, 16) mmHg and 15 (13, 18) mmHg, respectively. There was a poor correlation between the simultaneously measured PCWP and LVEDP (R2 = 0.03, p = 0.66). Conclusions: The PCWP may not correlate well with LVEDP in patients treated with VA-ECMO, particularly at high levels of VA-ECMO support.
RESUMEN
OBJECTIVES: Cardiac tumors are a rare and heterogeneous entity, with a cumulative incidence of up to 0.02%. This study aimed to investigate one of the largest patient cohorts for long-term outcomes after minimally-invasive cardiac surgery using right-anterior thoracotomy and femoral cardiopulmonary bypass (CPB) cannulation. METHODS: Between 2009 and 2021, patients who underwent minimally-invasive cardiac tumor removal at our department were included. The diagnosis was confirmed postoperatively by (immune-) histopathological analysis. Preoperative baseline characteristics, intraoperative data, and long-term survival were analyzed. RESULTS: Between 2009 and 2021, 183 consecutive patients underwent surgery for a cardiac tumor at our department. Of these, n = 74 (40%) were operated on using a minimally-invasive approach. The majority, n = 73 (98.6%), had a benign cardiac tumor, and 1 (1.4%) had a malignant cardiac tumor. The mean age was 60 ± 14 years, and n = 45 (61%) of patients were female. The largest group of tumors was myxoma (n = 62; 84%). Tumors were predominantly located in the left atrium in 89% (n = 66). CPB-time was 97 ± 36min and aortic cross-clamp time 43 ± 24 min s. The mean hospital stay was 9.7 ± 4.5 days. The perioperative mortality was 0%, and all-cause mortality after ten years was 4.1%. CONCLUSION: Minimally-invasive tumor excision is feasible and safe, predominantly in benign cardiac tumors, even in combination with concurrent procedures. Patients who require cardiac tumor removal should be evaluated for minimally-invasive cardiac surgery at a specialized center, as it is highly effective and associated with good long-term survival.

BACKGROUND: Myasthenia gravis (MG) is a rare neuromuscular disorder. Symptoms can range from ptosis only to life threatening myasthenic crisis. Thymectomy is recommended for anti-acetylcholine receptor-antibody positive patients with early-onset MG. Here, we investigated prognostic factors shaping therapeutic outcomes of thymectomy to improve patient stratification. METHODS: We retrospectively collected single-center data from a specialized center for MG from all consecutive adult patients that underwent thymectomy from 01/2012 to 12/2020. We selected patients with thymoma-associated and non-thymomatous MG for further investigations. We analyzed the patient collective regarding perioperative parameters in relation to the surgical approach. Furthermore, we investigated the dynamics of the anti-acetylcholine receptor-antibody titers and concurrent immunosuppressive therapies, as well as the therapeutic outcomes in dependence of clinical classifications. RESULTS: Of 137 patients 94 were included for further analysis. We used a minimally invasive approach in 73 patients, whereas 21 patients underwent sternotomy. A total of 45 patients were classified as early-onset MG (EOMG), 28 as late-onset MG (LOMG) and 21 as thymoma-associated MG (TAMG). The groups differed in terms of age at diagnosis (EOMG: 31.1 ± 12.2 years; LOMG: 59.8 ± 13.7 years; TAMG: 58.6 ± 16.7 years; p < 0.001). Patients with EOMG and TAMG were more often female than patients in the LOMG group (EOMG: 75.6%; LOMG: 42.9%; TAMG: 61.9%; p = 0.018). There were no significant differences in outcome scores (quantitative MG; MG activities of daily living; MG Quality of Live) with a median follow-up of 46 months. However, Complete Stable Remission was achieved significantly more frequently in the EOMG group than in the other two groups (p = 0.031). At the same time, symptoms seem to improve similarly in all three groups (p = 0.25). CONCLUSION: Our study confirms the benefit of thymectomy in the therapy of MG. Both, the concentration of acetylcholine receptor antibodies and the necessary dosage of cortisone therapy show a continuous regression after thymectomy in the overall cohort. Beyond EOMG, groups of LOMG and thymomatous MG responded to thymectomy as well, but therapy success was less pronounced and delayed compared to the EOMG subgroup. Thymectomy is a mainstay of MG therapy to be considered in all subgroups of MG patients investigated.
RESUMEN
OBJECTIVES: Skip-N2 metastasis (N0N2), thus N2 metastasis in the absence of N1 metastasis, occurs in â¼20-30% of non-small-cell lung cancer patients. N0N2 patients have a better prognosis than continuous-N2 metastasis (N1N2) patients following surgery. However, this effect remains controversial. Therefore, we conducted a multicentre study to compare the long-term survival and disease-free interval (DFI) of N1N2- and N0N2 patients. METHODS: One- and 3-year survival rates were measured. Kaplan-Meier curves and a Cox proportional hazards model assessed survival and were used to identify prognostic factors for overall survival. In addition, we performed propensity score matching (PSM) to rule out confounding factors. All patients received adjuvant chemoradiation therapy according to European guidelines. RESULTS: Between January 2010 and December 2020, 218 stage IIIA/B N2 patients were included in our analysis. The Cox regression analysis revealed that N1N2 significantly influenced the overall survival rate. Before PSM, N1N2 patients showed significantly more metastatic lymph nodes (P < 0.001) and significantly larger tumours (P = 0.05). After PSM, baseline characteristics did not differ between groups. Before and after PSM, N0N2 patients showed significantly better 1- (P = 0.01; P = 0.009) and 3-year (P < 0.001) survival rates than N1N2 patients. Furthermore, N0N2 patients showed significantly longer DFI than N1N2 patients before and after PSM (P < 000.1). CONCLUSIONS: Prior and after PSM analysis, N0N2 patients were confirmed to have better survival and DFI than N1N2 patients. Our results demonstrate that stage IIIA/B N2 patients are heterogeneous and would benefit from a more precise subdivision and differential treatment.

OBJECTIVES: Extracorporeal cardiopulmonary resuscitation (eCPR) is increasingly used due to its beneficial outcomes and results compared to conventional CPR. After cardiac arrest, the overall ejection fraction is severely impaired; thus, weaning from ECMO is often prolonged or impossible. We hypothesized that early application of levosimendan in these patients facilitates ECMO weaning and survival. METHODS: From 2016 until 2020, patients who underwent eCPR after cardiac arrest at our institution were analyzed retrospectively and divided into two groups: patients who received levosimendan during ICU stay (n = 24) and those who did not receive levosimendan (n = 84) and analyzed for outcome parameters. Furthermore, we used propensity-score matching and multinomial regression analysis to show the effect of levosimendan on outcome parameters. RESULTS: Overall, in-hospital mortality was significantly lower in the group which received levosimendan (28% vs. 88%, p ≤ 0.01), and ECMO weaning was more feasible in patients who received levosimendan (88% vs. 20%, p ≤ 0.01). CPR duration until ECMO cannulation was significantly shorter in the levosimendan group (44 + 26 vs. 65 + 28, p = 0.002); interestingly, the rate of mechanical chest compressions before ECMO cannulation was lower in the levosimendan group (50% vs. 69%, p = 0.005). CONCLUSION: In patients after cardiac arrest treated with eCPR, levosimendan seems to contribute to higher success rates of ECMO weaning, potentially due to a short to mid-term increase in inotropy. Also, the survival after levosimendan application was higher than patients who did not receive levosimendan.

BACKGROUND: The percentage of patients in resectable stages at initial diagnosis of non-small cell lung cancer (NSCLC) raises due to better screening programs. Therefore, risk prediction models are becoming more critical. Here, we validated and compared four established scoring models, the Thoracoscore, Epithor, Eurloung 2, and the simplified Eurolung 2 (2b), in their ability to predict 30-day mortality. METHODS: All consecutive patients undergoing anatomical pulmonary resection were included. The performance of the four scoring systems was assessed with Hosmer-Lemeshow goodness-of-fit test (calibration) and receiver operating characteristic (ROC) curves (discrimination). We compared the area under the curve (AUC) of the ROC curves by DeLong's method. RESULTS: A total of 624 patients underwent surgery for NSCLC at our institution between 2012 and 2018 30-day mortality was 2.2% (14 patients). The AUC for Eurolung 2 and the simplified Eurolung 2 (0.82) were greater than those of the other scoring systems, Epithor (0.71) and Thoracoscore (0.65). In addition, the DeLong analysis showed a significant superiority of Eurolung 2 and Eurolung 2b over the Thoracoscore (p = 0.04); there were no significant differences compared to Epithor. CONCLUSION: Eurolung 2 and the simplified Eurolung 2 were the favorable scoring systems for predicting 30-day mortality compared to Thoracoscore and Epithor. Therefore, we recommend using Eurolung 2 or the simplified Eurolung 2 for preoperative risk stratification.

BACKGROUND: One-third of non-small cell lung cancer (NSCLC) patients are diagnosed with locally advanced disease. Long-term survival in stage IIIA/B-N2 remains poor; this may also be due to lymph node spreading pattern. Therefore, we compared the overall survival of stage IIIA/B-N2 patients with superior mediastinal lymph nodes (SML) with infracarinal- or inferior mediastinal lymph nodes (IML) and with multilevel disease (MLD). RESEARCH DESIGN AND METHODS: One-, three-and five-year survival rates were measured. Kaplan-Meier curves and Cox proportional hazards model assessed survival and were used to identify prognostic factors. RESULTS: We reviewed data of stage IIIA/B-N2 patients (n = 129) who underwent surgery for NSCLC between 2012 and 2020. Patients with SML (n = 62) were compared to ILM (n = 37) and MLD (n = 30). SML patients showed significantly better one- (SML: 95.2% vs. IML: 78.6% vs. MLD: 69.4%, p = 0.03), three- (78.8% vs. 27.7 vs. 13.3%; p = <0.001) and five-year (61.1% vs. 17.1 vs. 3%; p < 0.001) survival rates, than IML and MLD patients. Kaplan-Meier curves showed prolonged overall survival for SML patients (log-rank SML, ILM, MLD p < 0.0001). CONCLUSIONS: This study showed significantly better long-term survival of SML patients than IML and MLD patients. The long-term survival of ILM and MLD patients was equally poor.

OBJECTIVES: The Ascyrus Medical Dissection Stent (AMDS) has been recently introduced as an alternative for total arch replacement in acute aortic dissection type A (AADA). The aim of this study was to evaluate the postoperative outcomes after AMDS treatment in a large contemporary cohort of AADA patients. METHODS: Data acquisition was performed retrospectively at 2 German aortic centres between 2020 and 2022 and comprised the perioperative parameters and postoperative results of all AADA patients. All patients treated with the AMDS for AADA were included in the study. The primary end point was in-hospital mortality. Secondary end points were defined as early postoperative and AMDS-related complications. RESULTS: Fifty-seven AADA patients treated by AMDS were included in the study group. The mean age was 64.6 ± 10.8 years and 59.7% (n = 34) were males. The actual in-hospital mortality was considerably lower than the predicted mortality risk by the German registry for acute aortic dissection type A score (16% vs 22%). The median ICU and in-hospital stay were 5 (interquartile range: 3-13) and 12 (interquartile range: 10-22) days, respectively. Postoperative complications comprised acute renal insufficiency (37%) with need for temporary (16%) or permanent dialysis (5%), delirium (26%), re-exploration for bleeding (14%), tracheostomy (14%) and new stroke (4%). A new AMDS-related complication (central stent collapse) was observed in 9% (n = 5) by postoperative computed tomography and chest X-ray. The incidence of complete central AMDS collapse did not impact 30-day mortality. CONCLUSIONS: The AMDS may be successfully used in AADA with acceptable 30-day mortality in accordance with the German registry for acute aortic dissection type A score. However, careful preoperative evaluation of the patient's individual aortic anatomy regarding potential contraindications and proper device implantation are strongly recommended to avoid complete central AMDS collapse.

OBJECTIVES: Extracorporeal cardiopulmonary resuscitation (eCPR) is increasingly used due to its beneficial outcomes and results compared with conventional CPR. Data after eCPR for acute kidney injury (AKI) are lacking. We sought to investigate factors predicting AKI in patients who underwent eCPR. METHODS: From January 2016 until December 2020, patients who underwent eCPR at our institution were retrospectively analyzed and divided into two groups: patients who developed AKI (n = 60) and patients who did not develop AKI (n = 35) and analyzed for outcome parameters. RESULTS: Overall, 63% of patients suffered AKI after eCPR and 45% of patients who developed AKI needed subsequent dialysis. Patients who developed AKI showed higher values of creatinine (1.1 mg/dL vs 1.5 mg/dL, p ⩽ 0.01), urea (34 mg/dL vs 42 mg/dL, p = 0.04), CK (creatine kinase) (923 U/L vs 1707 U/L, p = 0.07) on admission, and CK after 24 hours of ECMO support (1705 U/L vs 4430 U/L, p = 0.01). ECMO explantation was significantly more often performed in patients who suffered AKI (24% vs 48%, p = 0.01). In-hospital mortality (86% vs 70%; p = 0.07) did not differ significantly. CONCLUSION: Patients after eCPR are at high risk for AKI, comparable to those after conventional CPR. Baseline urea levels predict the development of AKI during the hospital stay.

There is an ongoing debate whether a surgical drainage is beneficial to prevent local accumulation of hematoma and to reduce the rate of wound infections, and neurological deficits. Data from the German Spine Society (DWG) registry were filtered for surgically treated spine tumor cases between 2017 and 2021. Cases were categorized into with (Group I) and without (Group II) placement of a surgical drainage. Subgroups were compared for demographic data, type of surgery, experience of the surgeon and postoperative surgical complications. 10,029 cases were included into final analysis (Group I: 3007; Group II: 7022). There was no significant difference between both groups regarding age or gender distribution. Average morbidity of patients was significantly elevated in Group I (p < 0.05) and the rates of invasive surgery were significantly increased in this group (p < 0.001). Overall complication rates were reported with 12.0% (Group I) and 8.5% (Group II). There were significantly more epidural hematoma (p < 0.001) and motor dysfunction (p = 0.049) as well as deep wound infections (p < 0.001) and implant failures (p = 0.02) in Group I. A surgical wound drainage cannot prevent epidural hematoma.

OBJECTIVE: Sublobar resection is frequently performed for Non-Small Cell Lung Cancer (NSCLC) patients with ≤2 cm nodules. Frequently, both proper staging and radical lymphadenectomy are omitted in these operations. Therefore, we decided to evaluate the number of lymph node metastases and the number of postoperative nodal upstaging in patients undergoing pulmonary resection due to NSCLC with tumors ≤2 cm at our institution. METHODS: Nodal upstaging, lymphangiosis- (L1), and hemangiosis carcinomatosa (V1) were analyzed. pN0 patients were compared to patients with postoperative nodal upstaging. One-, three, and five-year survival rates were measured. Survival was also assessed by the Kaplan-Meier method. RESULTS: 747 patients underwent surgery for NSCLC at our institution between 2012 and 2020. We retrospectively reviewed data of 236 NSCLC patients with ≤2 cm tumors. The mean tumor size was 1.4 cm ± 0.39 in our cohort. Of our patients, 14% showed a cT1a tumor, and 86% of patients cT1b. 24.0 ± 12.3 lymph nodes were dissected and analyzed per patient, and 0.7 ± 2.0 of those were affected. Of our patients, 16.1% showed L1 affection, and 7.6% a V1 affection. Lymph node involvement was diagnosed in 11(4.7%) patients preoperatively. 39(16.5%) patients were upstaged due to lymph node involvement postoperatively (p < 0.001). Upstaged patients showed significantly worse 3- (upstaged: 60.6% vs. pN0: 83.2%; p = 0.01) and 5-year (upstages: 38% vs. pN0 71.5%; p = 0.02) survival rates. CONCLUSION: 16.5% of patients with ≤2 cm NSCLC were nodal upstaged postoperatively. These results underline that lymphadenectomy and proper staging are crucial for NSCLC patients irrespective of the tumor size and the surgical approach.
