Abstract
Background: Hepatopancreato and biliary (HPB) tumors represent some of the leading cancer-related causes of death worldwide, with the majority of patients undergoing surgery in the context of a multimodal treatment strategy. Consequently, the implementation of an accurate risk stratification tool is crucial to facilitate informed consent, along with clinical decision making, and to compare surgical outcomes among different healthcare providers for either service evaluation or clinical audit. Perioperative troponin levels have been proposed as a feasible and easy-to-use tool in order to evaluate the risk of postoperative myocardial injury and 30-day mortality. The purpose of the present study is to validate the perioperative troponin levels as a prognostic factor regarding postoperative myocardial injury and 30-day mortality in Greek adult patients undergoing HPB surgery. Method: In total, 195 patients undergoing surgery performed by a single surgical team in a single tertiary hospital (2020-2022) were included. Perioperative levels of troponin before surgery and at 24 and 48 h postoperatively were assessed. Model accuracy was assessed by observed-to-expected (O:E) ratios, and area under the receiver operating characteristic curve (AUC). Survival at one year postoperatively was compared between patients with high and normal TnT levels at 24 h postoperatively. Results: Thirteen patients (6.6%) died within 30 days of surgery. TnT levels at 24 h postoperatively were associated with excellent discrimination and provided the best-performing calibration. Patients with normal TnT levels at 24 h postoperatively were associated with higher long-term survival compared to those with high TnT levels. Conclusions: TnT at 24 h postoperatively is an efficient risk assessment tool that should be implemented in the perioperative pathway of patients undergoing surgery for HPB cancer.

Abstract
Chronic heart failure (HF) is a clinical syndrome with high morbidity and mortality worldwide. Cardiac rehabilitation (CR) is a medically supervised program designed to maintain or improve cardiovascular health of people living with HF, recommended by both American and European guidelines. A CR program consists of a multispecialty group including physicians, nurses, physiotherapists, trainers, nutritionists, and psychologists with the common purpose of improving functional capacity and quality of life of chronic HF patients. Physical activity, lifestyle, and psychological support are core components of a successful CR program. CR has been shown to be beneficial in all ejection fraction categories in HF and most patients, who are stable under medication, are capable of participating. An individualized exercise prescription should be developed on the basis of a baseline evaluation in all patients. The main modalities of exercise training are aerobic exercise and muscle strength training of different intensity and frequency. It is important to set the appropriate clinical outcomes from the beginning, in order to assess the effectiveness of a CR program. There are still significant limitations that prevent patients from participating in these programs and need to be solved. A significant limitation is the generally low quality of research in CR and the presence of negative trials, such as the rehabilitation after myocardial infarction trial, where comprehensive rehabilitation following myocardial infraction had no important effect on mortality, morbidity, risk factors, or health-related quality of life or activity. In the present editorial, we present all the updated knowledge and recommendations in CR programs.

Abstract
Indication to perform surgical explantation of TAVR is becoming increasingly more frequent, due to the higher number of transcatheter procedures performed in patients with longer life expectancy. We proposed to perform a systematic review and meta-analysis with metaregression to identify potential factors that can determine an increase in the high mortality and morbidity that characterize these surgical procedures. MEDLINE and Embase were searched for relevant studies. Twelve studies were eligible according to our inclusion criteria. TAVR explantation was confirmed as a procedure with high 30-day mortality (0.17; 95% CI, 0.14-0.21) and morbidity (stroke incidence 5%; 95% CI, 0.04-0.07; kidney injury incidence 16%; 95% CI, 0.11-0.24). The type of transcatheter valve implanted during the index procedure did not influence the outcomes after surgical explantation. The role of these high-risk operations is growing, and it will likely expand in the coming years. Specific tools for risk stratification are required.

Abstract
Infective endocarditis (IE) is a severe cardiac complication with high mortality rates, especially when surgical intervention is delayed or absent. This review addresses the expanding role of surgery in managing IE, focusing on the variation in surgical treatment rates, the impact of patient demographics, and the effectiveness of different surgical approaches. Despite varying global data, a notable increase in surgical interventions for IE is evident, with over 50% of patients undergoing surgery in tertiary centres. This review synthesizes information from focused literature searches up to July 2023, covering preoperative to postoperative considerations and surgical strategies for IE. Key preoperative concerns include accurate diagnosis, appropriate antimicrobial treatment, and the timing of surgery, which is particularly crucial for patients with heart failure or at risk of embolism. Surgical approaches vary based on valve involvement, with mitral valve repair showing promising outcomes compared to replacement. Aortic valve surgery, traditionally favouring replacement, now includes repair as a viable option. Emerging techniques such as sutureless valves and aortic homografts are explored, highlighting their potential advantages in specific IE cases. The review also delves into high-risk groups like intravenous drug users and the elderly, emphasizing the need for tailored surgical strategies. With an increasing number of patients presenting with prosthetic valve endocarditis and device-related IE, the review underscores the importance of comprehensive management strategies encompassing surgical and medical interventions. Overall, this review provides a comprehensive overview of current evidence in the surgical management of IE, highlighting the necessity of a multidisciplinary approach and ongoing research to optimize patient outcomes.

Abstract
Heart transplantation (HTx) remains the last therapeutic resort for patients with advanced heart failure. The present work is a clinically focused review discussing current issues in heart transplantation. Several factors have been associated with the outcome of HTx, such as ABO and HLA compatibility, graft size, ischemic time, age, infections, and the cause of death, as well as imaging and laboratory tests. In 2018, UNOS changed the organ allocation policy for HTx. The aim of this change was to prioritize patients with a more severe clinical condition resulting in a reduction in mortality of people on the waiting list. Advanced heart failure and resistant angina are among the main indications of HTx, whereas active infection, peripheral vascular disease, malignancies, and increased body mass index (BMI) are important contraindications. The main complications of HTx include graft rejection, graft angiopathy, primary graft failure, infection, neoplasms, and retransplantation. Recent advances in the field of HTx include the first two porcine-to-human xenotransplantations, the inclusion of hepatitis C donors, donation after circulatory death, novel monitoring for acute cellular rejection and antibody-mediated rejection, and advances in donor heart preservation and transportation. Lastly, novel immunosuppression therapies such as daratumumab, belatacept, IL 6 directed therapy, and IgG endopeptidase have shown promising results.

Abstract
Early risk stratification is of outmost clinical importance in hospitalized patients with heart failure (HHF). We examined the predictive value of the Larissa Heart Failure Risk Score (LHFRS) in a large population of HHF patients from the Cleveland Clinic. A total of 13,309 admissions for heart failure (HF) from 9207 unique patients were extracted from the Cleveland Clinic's electronic health record system. For each admission, components of the 3-variable simple LHFRS were obtained, including hypertension history, myocardial infarction history, and red blood cell distribution width (RDW) ≥ 15%. The primary outcome was a HF readmission and/or all-cause mortality at one year, and the secondary outcome was all-cause mortality at one year of discharge. For both outcomes, all variables were statistically significant, and the Kaplan-Meier curves were well-separated and in a consistent order (Log-rank test p-value < 0.001). Higher LHFRS values were found to be strongly related to patients experiencing an event, showing a clear association of LHFRS with this study outcomes. The bootstrapped-validated area under the curve (AUC) for the logistic regression model for each outcome revealed a C-index of 0.64 both for the primary and secondary outcomes, respectively. LHFRS is a simple risk model and can be utilized as a basis for risk stratification in patients hospitalized for HF.

Abstract
OBJECTIVE Thoracic aortic aneurysm dissection (TAAD) represents a cardiac surgery emergency characterized by the disrupted integrity of the aortic wall and is associated with poor prognosis. In this context, the identification of biomarkers implicated in the pathobiology of TAAD is crucial. Our aim in the present original in silico study is to assess the differential gene expression profile of the tight junction proteins (TJPs) in patients with TAAD and to propose novel biomarkers for the diagnosis and prognosis of this disease. METHODS We implemented bioinformatics methodology in order to construct the gene network of the TJPs family, identify the differentially expressed genes (DEGs) in pathologic aortic tissue excised from patients with TAAD as compared to healthy aortic tissue, and assess the related biological functions and the associated miRNA families. RESULTS Data regarding the transcriptomic profile of selected genes were retrieved and incorporated from three microarray datasets, including 23 TAAD and 20 healthy control samples. A total of 32 TJPs were assessed. The zona occludens 2 (ZO-2) protein encoded by the gene TJP2 was significantly under-expressed in patients with TAAD compared to the control group (p = 0.009). ZO-2 was associated with fair discrimination and calibration traits in predicting the TAAD presentation. CpG islands of ZO-2 were demonstrated. No important difference was found regarding ZO-2 expression between aneurysmal non-dissected and healthy control aortic tissue. Finally, we performed gene set enrichment analysis (GSEA) and uncovered the major biological functions and miRNA families (hsa-miR-155-5p, hsa-miR-1-3p, hsa-miR-2118-5p, hsa-miR-4691-3p, and hsa-miR-1229-3p) relevant to ZO-2. CONCLUSIONS These outcomes demonstrated the important role of ZO-2 in the pathobiology of TAAD.

Abstract
The frozen elephant trunk is a formidable tool for the aortovascular surgeon. An appreciation of how to size the graft in different pathologies is key in achieving optimal results. Herein, we demonstrate worked examples of how imaging can be used to plan for a frozen elephant trunk and discuss the nuisances and uncertainties of sizing using three index cases: Type A aortic dissection, distal thoracic aortic aneurysm and chronic dissection.

Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) mostly occurs when there is an acute insult to the liver in patients with pre-existing liver disease, and it is characterized by a high mortality rate. Various therapeutic approaches have been used thus far, with orthotopic liver transplantation being the only definitive cure. Clinical trials and meta-analyses have investigated the use of granulocyte colony-stimulating factor (G-CSF) to mobilize bone marrow-derived stem cells. Some studies have suggested that G-CSF may have a significant role in the management and survival of patients with ACLF. However, the results are conflicting, and the efficacy of G-CSF still needs to be confirmed. AIM The aim was to assess the efficacy of G-CSF in patients with ACLF. METHODS Electronic databases were searched until May 2023 for randomized controlled trials investigating the use of G-CSF in adult patients with ACLF. Outcome measures were the effects of G-CSF on overall survival, changes in liver disease severity scores, complications of cirrhosis, other G-CSF-related adverse effects, and all-cause mortality. The study's protocol has been registered with Prospero (CRD42023420273). RESULTS Five double-blind randomized controlled trials involving a total of 421 participants met the inclusion criteria. The use of G-CSF demonstrated a significant effect on overall survival (HR 0.63, 95% CI 0.41 to 0.95, and I2 48%), leading to a decreased mortality (LogOR-0.97, 95% CI -1.57 to -0.37, and I2 37.6%) and improved Model for End-Stage Liver Disease (MELD) scores (SMD -0.87, 95% CI -1.62 to -0.13, and I2 87.3%). There was no correlation between the improvement of the Child-Pugh score and the use of G-CSF(SMD -2.47, 95% CI -5.78 to 0.83, and I2 98.1%). The incidence of complications of cirrhosis did not decrease significantly with G-CSF treatment (rate ratio 0.51, 95% CI 0.26 to 1.01, and I2 90%). A qualitative synthesis showed that the use of G-CSF is safe. CONCLUSIONS The administration of G-CSF has demonstrated a positive impact on overall survival, liver function, and the MELD score. The presence of heterogeneity in the included studies prohibits conclusive recommendations.

Abstract
The function of the kidney is tightly linked to the function of the heart. Dysfunction/disease of the kidney may initiate, accentuate, or precipitate of the cardiac dysfunction/disease and vice versa, contributing to a negative spiral. Further, the reciprocal association between the heart and the kidney may occur on top of other entities, usually diabetes, hypertension, and atherosclerosis, simultaneously affecting the two organs. Chronic kidney disease (CKD) can influence cardiac function through altered hemodynamics and salt and water retention, leading to venous congestion and therefore, not surprisingly, to heart failure (HF). Management of HF in CKD is challenging due to several factors, including complex interplays between these two conditions, the effect of kidney dysfunction on the metabolism of HF medications, the effect of HF medications on kidney function, and the high risk for anemia and hyperkalemia. As a result, in most HF trials, patients with severe renal impairment (i.e., eGFR 30 mL/min/1.73 m2 or less) are excluded. The present review discusses the epidemiology, pathophysiology, and current medical management in patients with HF developing in the context of CKD.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are a relatively new class of antidiabetic drugs that have shown favorable effects in heart failure (HF) patients, irrespective of the left ventricular ejection fraction (LVEF). Recent studies have demonstrated the beneficial effects of empagliflozin on cardiac function and structure; however, less is known about dapagliflozin. The purpose of the current work was to investigate the association between the use of dapagliflozin and cardiac biomarkers as well as the cardiac structure in a cohort of patients with HF and diabetes mellitus (DM). The present work was an observational study that included 118 patients (dapagliflozin group n = 60; control group n = 58) with HF and DM. The inclusion criteria included: age > 18 years, a history of DM and HF, regardless of LVEF, and hospitalization for HF exacerbation within the previous 6 months. The exclusion criteria were previous treatment with SGLT2i or glucagon-like peptide-1 receptor agonists, a GFR< 30 and life expectancy < 1 year. The evaluation of patients (at baseline, 6 and 12 months) included a clinical assessment, laboratory blood tests and echocardiography. The Mann-Whitney test was used for the comparison of continuous variables between the two groups, while Friedman's analysis of variance for repeated measures was used for the comparison of continuous variables. Troponin (p < 0.001) and brain natriuretic peptide (BNP) (p < 0.001) decreased significantly throughout the follow-up period in the dapagliflozin group, but not in the control group (p > 0.05 for both). The LV end-diastolic volume index (p < 0.001 for both groups) and LV end-systolic volume index (p < 0.001 for both groups) decreased significantly in the dapagliflozin and the control group, respectively. The LVEF increased significantly (p < 0.001) only in the dapagliflozin group, whereas the global longitudinal strain (GLS) improved in the dapagliflozin group (p < 0.001) and was impaired in the control group (p = 0.021). The left atrial volume index decreased in the dapagliflozin group (p < 0.001) but remained unchanged in the control group (p = 0.114). Lastly, the left ventricular mass index increased significantly both in the dapagliflozin (p = 0.003) and control group (p = 0.001). Dapagliflozin, an SGLT2i, was associated with a reduction in cardiac biomarkers and with reverse cardiac remodeling in patients with HF and DM.

Abstract
Despite overwhelming epidemiological evidence, the contribution of hypertension (HTN) to heart failure (HF) development has been undermined in current clinical practice. This is because approximately half of HF patients have been labeled as suffering from HF with preserved left ventricular (LV) ejection fraction (EF) (HFpEF), with HTN, obesity, and diabetes mellitus (DM) being considered virtually equally responsible for its development. However, this suggestion is obviously inaccurate, since HTN is by far the most frequent and devastating morbidity present in HFpEF. Further, HF development in obesity or DM is rare in the absence of HTN or coronary artery disease (CAD), whereas HTN often causes HF per se. Finally, unlike HTN, for most major comorbidities present in HFpEF, including anemia, chronic kidney disease, pulmonary disease, DM, atrial fibrillation, sleep apnea, and depression, it is unknown whether they precede HF or result from it. The purpose of this paper is to provide a contemporary overview on hypertensive HF, with a special emphasis on its inflammatory nature and association with autonomic nervous system (ANS) imbalance, since both are of pathophysiologic and therapeutic interest.

Abstract
OBJECTIVE The aim of the present series was first to present our experience in the management of 37 patients with spontaneous pneumomediastinum (SPM), and further to indicate the necessity of identifying true SPM cases as they are currently inadequately defined. METHODS This is a single-center, retrospective study, conducted in a university hospital. Consecutive adult patients with pneumomediastinum (PM) between January 2009 and March 2020 were involved in the series. The data about age, gender, symptoms, signs, treatment, length of hospital stay (LOS), and in-hospital mortality were evaluated. RESULTS In total, 87 cases with pneumomediastinum (37 with spontaneous and 50 with secondary PM) were analyzed. Patients in both groups were of similar ages (P=0.4). Sufferers with secondary PM were more likely to have: an associated pneumothorax (19% vs 58%, P<0.05), a chest tube placed (18.9% vs 58%, P<0.05), an associated pleural effusion (0% vs 18%, P<0.05). They presented with a longer LOS (3.9 vs 5.3 days, P<0.05), and were more likely to die (0% vs 10%, P<0.05). Additionally they showed a higher prevalence of radiologic subcutaneous emphysema (49% vs 74%, P<0.05). CONCLUSION Spontaneous pneumomediastinum is an onset of clinical importance with a low mortality rate, short LOS and good longterm prognosis. It often presents with chest pain, dyspnea and/or subcutaneous emphysema. However, secondary causes of mediastinal air must be ruled out, due to their potential devastating outcome if not diagnosed promptly. A consensus aimed at an update of the classification guidelines is more than indispensable.

Abstract
The Michigan Society of Thoracic and Cardiovascular Surgeons (MSTCVS), a pioneer in initiating and nurturing quality improvement strategies in statewide cardiothoracic surgery, has been running the Quality Collaborative (MSTCVS-QC) program since 2001. This initiative has significantly grown over the years, facilitating at least 4 in-person meetings annually. It actively engages cardiac and general thoracic surgeons, data managers and researchers from all 32 non-federally funded cardiothoracic surgery sites across Michigan. Broadening its influence on joint learning and clinical outcomes, the MSTCVS-QC formed a strategic partnership with Blue Cross Blue Shield of Michigan, the state's largest private insurer, to further promote its initiatives. The MSTCVS-QC, operating from a dedicated QC centre employs an STS-associated database with additional aspects for data collection and analysis. The QC centre also organizes audits, facilitates collaborative meetings, disseminates surgical outcomes and champions the development and implementation of quality improvement initiatives related to cardiothoracic surgery in Michigan. Recognizing the MSTCVS-QC's successful efforts in advancing quality improvement, the European Association for Cardiothoracic Surgery (EACTS) introduced a fellowship program in 2018, facilitated through the EACTS Francis Fontan Fund (FFF). This program allows early-career academic physicians to spend 4-6 months with the MSTCVS-QC team in Ann Arbor. This article chronicles the evolution and functionality of the MSTCVS-QC, enriched by the experiences of the inaugural 4 EACTS/FFF fellows. Our objective is to emphasize the critical importance of fostering a culture of quality improvement and patient safety in the field of cardiothoracic surgery with open discussion of audited, high-quality data points. This principle, while implemented locally, has implications and value extending far beyond Europe, resonating globally.

Abstract
OBJECTIVE Due to an ever-increasing ageing population and limited available data around the use of thoracic endovascular aortic repair (TEVAR) in elderly patients, investigating its efficacy and safety in this age cohort is of vital importance. We thus reviewed the existing literature on this topic to assess the feasibility of TEVAR in elderly patients with severe thoracic aortic pathologies. METHODS We identified all original research studies that assessed TEVAR in elderly patients published up to 2023. Morbidity, as assessed by neurological and respiratory complications, endoleaks, and length of stay, was the primary endpoint. Short-term mortality and long-term survival were the secondary endpoints. The Mantel-Haenszel random and fixed effects methods were used to calculate the odds ratios for each outcome. Further sensitivity and subgroup analyses were performed to validate the outcomes. RESULTS Twelve original studies that evaluated elective TEVAR outcomes in elderly patients were identified. Seven studies directly compared the use of TEVAR between an older and a younger patient group. Apart from a shorter hospital stay in older patients, no statistically significant difference between the morbidity outcomes of the two different cohorts was found. Short-term mortality and long-term survival results favoured the younger population. CONCLUSIONS The present meta-analysis indicates that, due to a safe perioperative morbidity profile, TEVAR should not be contraindicated in patients based purely on old age. Further research using large patient registries to validate our findings in elderly patients with specific aortic pathologies and both elective and emergency procedures is necessary.

Abstract
We conducted a thorough literature review on the emerging role of failure to rescue (FTR) as a quality metric for cardiovascular surgery and critical care. For this purpose, we identified all original research studies assessing the implementation of FTR in cardiovascular surgery and critical care from 1992 to 2023. All included studies were evaluated for their quality. Although all studies defined FTR as mortality after a surgical complication, a high heterogeneity has been reported among studies regarding the included complications. There are certain factors that affect the FTR, divided into hospital- and patient-related factors. The identification of these factors allowed us to build a stepwise roadmap to reduce the FTR rate. Recently, FTR has further evolved as a metric to assess morbidity instead of mortality, while being also evaluated in the context of interventional cardiology. All these advances are further discussed in the current review, thus providing all the necessary information to surgeons, anesthesiologists, and physicians willing to implement FTR as a metric of quality in their establishment.

Differences in long-term survival outcomes after coronary artery bypass grafting using single vs multiple arterial grafts: a meta-analysis with reconstructed time-to-event data and subgroup analyses. Gen Thorac Cardiovasc Surg 2023; 71:77-89. [PMID: 36394709 PMCID: PMC9886578 DOI: 10.1007/s11748-022-01891-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [What about the content of this article?

Abstract
OBJECTIVE We reviewed the available literature on patients with coronary artery disease undergoing isolated coronary artery bypass grafting (CABG) with either single (SAG) or multiple arterial grafting (MAG). METHODS Original research studies that evaluated the long-term survival of MAG versus SAG were identified, from 1995 to 2022. The median overall survival (OS) and event-free OS were the primary endpoints. Comparison of median OS between the right internal mammary artery (RIMA) and radial artery (RA) as a second arterial conduit was the secondary endpoint. Subgroup analyses were performed regarding patients older than 70 years, with diabetes mellitus, and females. A sensitivity analysis was performed with the leave-one-out method. RESULTS Forty-four studies were included in the qualitative and thirty-nine in the quantitative synthesis. After pooling data from 180 to 459 patients, the MAG group demonstrated a higher OS (HR, 0.589; 95% CI, 0.58-0.60; p < 0.0001) and event-free OS compared with the SAG group (HR, 0.828; 95% CI, 0.80-0.86; p < 0.0001). In addition, RITA was associated with superior OS compared with RA as a second arterial conduit (HR, 0.936; 95% CI, 0.89-0.98; p = 0.009). MAG was also superior to SAG in patients over 70 years, females, and patients with diabetes mellitus. Sensitivity analysis demonstrated a small-size study effect on the female subgroup analysis. CONCLUSION The present meta-analysis indicates that MAG is associated with enhanced survival outcomes compared to SAG for patients undergoing isolated CABG.

Abstract
OBJECTIVE We conducted a thorough literature search on patients with central non-small cell lung cancer (NSCLC) undergoing either extended sleeve lobectomy (ESL) or pneumonectomy (PN). METHODS We identified all original research studies that compared the long-term survival of ESL versus PN from 1990 to 2022. The primary endpoints were the median overall survival (OS) and disease-free survival (DFS). Complications, operative mortality, and the reoperation rate were the secondary endpoints. Regarding the primary endpoints, independent patient data were extracted from the included studies, and pooled Kaplan-Meier curves were constructed. A sensitivity analysis was performed using the leave-one-out method. RESULTS Nine studies were included in the qualitative and seven in the quantitative synthesis, including 431 patients. Patients in the ESL group demonstrated a significantly higher OS compared with the PN group (HR, 0.63; 95% CI, 0.46-0.87; p = 0.005). In addition, patients undergoing ESL presented a significantly higher DFS compared to the PN group (HR, 0.57; 95% CI, 0.40-0.80; p = 0.004). These findings were further validated with a sensitivity analysis. The most common complications in the ESL group were bronchopleural fistula (4.6%), stricture (3.1%), prolonged air leakage (7.3%), sputum retention (4.6%), pneumonia (7.7%), and pulmonary vein thrombosis (1.5%). ESL was associated with a low reoperation rate (1.5%) and operative mortality (1.2%). CONCLUSIONS The present meta-analysis indicates that ESL is associated with enhanced survival outcomes compared to PN for patients with central NSCLC. Further randomized controlled trials are necessary to validate our findings.

Abstract
Objectives: The aim of the present study was to analyze the differential gene expression of BCL-xL/BCL2L and the associated genetic, molecular, and biologic functions in pancreatic ductal adenocarcinoma (PDAC) by employing advanced bioinformatics to investigate potential candidate genes implicated in the pathogenesis of PDAC. Materials and Methods: Bioinformatic techniques were employed to build the gene network of BCL-xL, to assess the translational profile of BCL-xL in PDAC, assess its role in predicting PDAC, and investigate the associated biologic functions and the regulating miRNA families. Results: Microarray data extracted from one dataset was incorporated, including 130 samples (PDAC: 69; Control: 61). In addition, the expression level of BCL-xL was higher in PDAC compared to control samples (p < 0.001). Furthermore, BCL-xL demonstrated excellent discrimination (AUC: 0.83 [95% Confidence Intervals: 0.76, 0.90]; p < 0.001) and calibration (R squared: 0.31) traits for PDAC. A gene set enrichment analysis (GSEA) demonstrated the molecular functions and miRNA families (hsa-miR-4804-5p, hsa-miR-4776-5p, hsa-miR-6770-3p, hsa-miR-3619-3p, and hsa-miR-7152-3p) related to BCL-xL. Conclusions: The current findings unveil the biological implications of BCL-xL in PDAC and the related molecular functions and miRNA families.

Abstract
An outbreak of coronavirus disease 2019 (COVID-19) occurred in December 2019 due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is a strain of SARS-CoV. Patients infected with the virus present a wide spectrum of manifestations ranging from mild flu-like symptoms, cough, fever and fatigue to severe lung injury, appearing as bilateral interstitial pneumonia or acute respiratory failure. Although SARS-CoV-2 infection predominantly offends the respiratory system, it has been associated with several cardiovascular complications as well. For example, patients with COVID-19 may either develop type 2 myocardial infarction due to myocardial oxygen demand and supply imbalance or acute coronary syndrome resulting from excessive inflammatory response to the primary infection. The incidence of COVID-19 related myocarditis is estimated to be accountable for an average of 7% of all COVID-19 related fatal cases, whereas heart failure (HF) may develop due to infiltration of the heart by inflammatory cells, destructive action of pro-inflammatory cytokines, micro-thrombosis and new onset or aggravated endothelial and respiratory failure. Lastly, SARS-CoV-2 can engender arrhythmias through direct myocardial damage causing acute myocarditis or through HF decompensation or secondary, through respiratory failure or severe respiratory distress syndrome. In this comprehensive review we summarize the COVID-19 related cardiovascular complications (acute coronary syndromes, myocarditis, HF, arrhythmias) and discuss the main underlying pathophysiological mechanisms.

Abstract
Background This review aims to systematically evaluate the currently available evidence investigating the use of artificial intelligence (AI) and machine learning (ML) in the field of cardiac transplantation. Furthermore, based on the challenges identified we aim to provide a series of recommendations and a knowledge base for future research in the field of ML and heart transplantation. Methods A systematic database search was conducted of original articles that explored the use of ML and/or AI in heart transplantation in EMBASE, MEDLINE, Cochrane database, and Google Scholar, from inception to November 2021. Results Our search yielded 237 articles, of which 13 studies were included in this review, featuring 463 850 patients. Three main areas of application were identified: (1) ML for predictive modeling of heart transplantation mortality outcomes; (2) ML in graft failure outcomes; (3) ML to aid imaging in heart transplantation. The results of the included studies suggest that AI and ML are more accurate in predicting graft failure and mortality than traditional scoring systems and conventional regression analysis. Major predictors of graft failure and mortality identified in ML models were: length of hospital stay, immunosuppressive regimen, recipient's age, congenital heart disease, and organ ischemia time. Other potential benefits include analyzing initial lab investigations and imaging, assisting a patient with medication adherence, and creating positive behavioral changes to minimize further cardiovascular risk. Conclusion ML demonstrated promising applications for improving heart transplantation outcomes and patient‐centered care, nevertheless, there remain important limitations relating to implementing AI into everyday surgical practices.

Abstract
BACKGROUND/AIM Pancreatic cancer (PC) is one of the leading causes of cancer-related death. The purpose of the present study was to establish a patient-derived orthotopic xenograft model (PDOX) for pancreatic ductal adenocarcinoma (PDAC), thus providing a tumor microenvironment resembling that of the human pancreas to identify novel potential biomarkers and treatment regimens. MATERIALS AND METHODS PDAC tissue samples were received from 35 patients, following informed consent, and three mouse strains were implemented. RESULTS Successful PDOX engraftment was performed in nonobese diabetic/severe combined immunodeficient (NOD/SCID) and NOD/SCID gamma (NSG) mice. Nonetheless, we found a higher rate of successful engraftment and tumor growth in NSG compared to NOD/SCID mice, possibly owning to the different level of immunosuppression and more specifically of the natural killer cells presence. CONCLUSION Our suggested PDOX model represents a preclinical cancer research model with a high affinity for the patient's tumor microenvironment, thus enabling the acceleration of PDAC research.

Abstract
BACKGROUND This study aimed to evaluate the outcomes of high-intensity focused ultrasound (HIFU) on patients with advanced pancreatic cancer. METHODS A literature search was performed in PubMed, Scopus and Cochrane databases, in accordance with the PRISMA guidelines. The Odds Ratio, Weighted Mean Difference, and 95% Confidence Interval were evaluated by means of the Random-Effects model. RESULTS Nineteen articles met the inclusion criteria, incorporating 939 patients. This study reveals that patients in the HIFU group presented increased median overall survival (OS), along with higher OS at 6 and 12 months after treatment compared with the control group (p < 0.05). Furthermore, patients treated with HIFU in conjunction with chemotherapy presented reduced levels of pain (p < 0.05) compared to the traditional treatment group. In addition, HIFU contributed to significant tumor responsiveness, in terms of CA19-9 reduction (p < 0.05). Finally, HIFU was a considerably safe treatment modality with a low incidence of complications. CONCLUSION These outcomes suggest that HIFU is a feasible and safe treatment modality for patients with advanced pancreatic cancer and provides enhanced outcomes regarding survival and quality of life. Given the lack of a significant number of randomized clinical trials, this meta-analysis represents the best currently available evidence. New randomized trials assessing HIFU are necessary to further evaluate their outcomes.

Abstract
Bile duct injuries represent the most dramatic complications after an open or laparoscopic cholecystectomy. The detrimental effects on patient quality of life and overall survival are the most obvious consequences of such injuries. An effective treatment strategy after accurate mapping of the injury type is the only method of averting these morbid consequences. Several classification systems have been proposed in an attempt to accurately describe and categorize bile duct injuries. The critical question is whether we truly need all these systems and whether each of these systems adds value to the existing knowledge base, or further obscures the field. Each classification system has several advantages to base its clinical utility on, but entails a reasonable number of limitations as well. Currently, a tailored approach adopting the classification system which provides the most appropriate guidance - either in terms of diagnosis or treatment decision making - appears to be the most justified option.

Abstract
BACKGROUND This study aimed to assess the outcomes of contrast-enhanced intraoperative ultrasound (CE-IOUS) for patients with colorectal liver metastases (CRLMs) undergoing surgery. METHOD A thorough literature search was performed in PubMed, Scopus, and Cochrane databases, in accordance with the PRISMA guidelines. The Odds Ratio, Weighted Mean Difference, and 95% Confidence Interval were evaluated, by means of Random-Effects model. RESULTS Eleven articles met the inclusion criteria and incorporated 497 patients. The present study shows that CE-IOUS is associated with higher sensitivity and accuracy compared with multidetector computed tomography (MDCT), magnetic resonance imaging (MRI), and intraoperative ultrasound (IOUS) in identifying CRLMs (p < 0.05). The positive predictive value was similar among the different modalities. Furthermore, new CRLMs were identified by CE-IOUS, thus affecting the surgical plan in 128 patients (51.8% of the patients with new CRLMs). Moreover, 91 patients (71%) underwent a more extensive hepatectomy and 15 patients (11.7%) were considered non-operable. Two alternative contrast agents, Sonazoid and Sonovue, were employed with similar sensitivity (p > 0.05). CONCLUSION These outcomes suggest the superiority of the CE-IOUS over MDCT, MRI, and IOUS for the staging of patients with CRLMs undergoing surgery. However, they should be treated with caution given the small number of the included studies.

Abstract
OBJECTIVES Thoracic aortic aneurysm (TAA) is characterized by the dilation of the aorta and is associated with poor prognosis if not diagnosed and treated early. In this context, the identification of biomarkers regarding the TAA diagnosis, monitoring and prognosis is crucial. The purpose of the current study was to investigate the differential gene expression profile of the cadherin 5 (CDH5 or VE-Cadherin) gene network in patients with TAA, to propose novel biomarkers. METHODS In silico techniques were used to construct the interactome of the CDH5 network, identify the differentially expressed genes (DEGs) in TAA as compared to healthy controls, and uncover the related molecular functions and the regulating miRNAs. RESULTS Transcriptomic data of one microarray dataset were included, incorporating 43 TAA and 43 control samples. Eight DEGs were identified; 7 were up-regulated and 1 was down-regulated. A molecular signature of 8 genes (CDH5; Calcitonin Receptor-Like Receptor-CALCRL; Activin A Receptor-Like Type 1-ACVRL1, Tryptophanyl-TRNA Synthetase 1-WARS; Junction Plakoglobin-JUP, Protein Tyrosine Phosphatase Receptor Type J-PTPRJ, Purinergic Receptor P2X 4-P2RX4, Kinase Insert Domain Receptor-KDR) were identified as biomarkers associated with TAA. PTPRJ was associated with excellent discrimination and calibration in predicting TAA presentation. Positive correlations were reported regarding the expression of CDH5-CALCRL, CDH5-ACVRL1, CDH5-WARS and CDH5-PTPRJ. Finally, gene set enrichment analysis indicated the molecular functions and miRNA families (hsa-miR-296-5p, hsa-miR-6836-5p, hsa-miR-6132, hsa-miR-27a-5p and hsa-miR-6773-5p) relevant to the 8 biomarkers. CONCLUSIONS These outcomes propose an 8-gene molecular panel associated with TAA.

Abstract
Although myxoma represents the most frequent non-malignant cardiac primary tumor; it is extremely rare met in the left ventricle. Clinical features of the neoplasm extend from symptomless to critical signs of either ischemia or embolism. We describe here an unusual case of a huge left ventricular myxoma in a 68-year-old man, presented with clinical and ECG findings of an inferior wall myocardial infarction. The patient was primarily referred to our institution for coronary angiography, which showed no coronary artery disease. Further examinations revealed a left ventricular mass as the possible source of embolization, thus the patient underwent surgery for tumor excision. The postoperative course was unremarkable. A bibliographical analysis demonstrated that those tumors are rare but treatable causes of embolic myocardial infarction, thus profound clinical intuition, proper utilization of imaging modalities, administration of anticoagulants preoperatively, as well immediate surgical removal are justified.

Abstract
INTRODUCTION The purpose of the current study was to review the available literature on morbidly obese patients treated with laparoscopic Roux-en-Y gastric bypass (LRYGB) in order to assess the clinical outcomes of the routine closure of the mesenteric defects. METHODS A literature search was performed in PubMed, Cochrane library, and Scopus, in accordance with the PRISMA guidelines. RESULTS Nine studies met the inclusion criteria. A total of 16,520 patients were incorporated with a mean follow-up ranging from 34 to 120 months. The closure of the mesenteric defects was associated with a lower incidence of internal hernias (odds ratio, 0.25 [95% confidence interval 0.20, 0.31]; p < 0.01), small bowel obstruction (SBO) (0.30 [0.17, 0.52]; p < 0.0001) and reoperations (0.28 [0.15, 0.52]; p < 0.001). Both approaches presented similar complication rates and % excess weight loss (%EWL). CONCLUSION The present meta-analysis is the best currently available evidence on the topic and supports the routine closure of the mesenteric defects.

Abstract
Background: Colectomies performed according to complete mesocolic excision with central vascular ligation (CME-CVL) principles have been associated with enhanced oncologic outcomes. Nonetheless, laparoscopic CME-CVL right hemicolectomy has not been widely adopted. We aimed to compare the perioperative and pathology outcomes of laparoscopic and open CME-CVL right hemicolectomy. Materials and Methods: We compared data from a prospectively collected database regarding patients who underwent either laparoscopic or open CME-CVL right hemicolectomy for nonmetastatic right colon cancer in a University Hospital, between January 2012 and December 2018. Results: A total of 130 consecutive patients were included in the study. Of them, 73 patients underwent laparoscopic and 57 patients open right colectomy, following the CME-CVL principles. The laparoscopic approach was associated with less hospital stay (6.6 versus 9.1 days; P < .001) and septic complications (P = .046), at a cost of an increased operative time (180 versus 125.1 minutes; P < .001). Patients treated with either open or laparoscopic approach presented similar outcomes regarding pathology endpoints. In fact, both groups demonstrated similar R0 resection rate (P = .202), number of harvested and positive lymph nodes (P = .751 and P = .734, respectively), number of harvested lymph nodes at the level of D1 and D2 lymph node dissection (P > .05), rate of vascular (P = .501), and perineural infiltration (P = .956). Furthermore, no difference was found regarding the rate of intact mesocolic plane (P = .799), along with the tumor diameter (P = .154) and the length of specimen (P = .163). Conclusion: Laparoscopic CME-CVL right hemicolectomy appears to offer certain advantages in short-term outcomes compared to open procedure. Pathology outcomes did not differ between the two approaches. Future studies should further evaluate their long-term outcomes.

Abstract
Leiomyosarcomas of the spermatic cord are rare malignancies with only sporadic cases (less than 150) reported in the literature. Preoperative diagnosis of a paratestical leiomyosarcoma is challenging. Clinicians do not typically consider inguinoscrotal lumps as underlying sarcomas due to their relatively low prevalence compared with hernias. As a result the diagnosis of a sarcoma of the paratesticular area is often hard to reach. Herein, we report a rare case of a leiomyosarcoma originating from the spermatic cord, masquerading as a strangulated inguinal hernia. Intraoperatively, a mass arising from the spermatic cord was found and excised. A supplementary orchiectomy with high ligation of the spermatic cord was also performed.

Abstract
Objective We reviewed the available literature on patients with lung cancer undergoing either uniportal (UVATS) or multiport video-assisted thoracoscopic surgery (MVATS). Methods Original research studies that evaluated perioperative and long-term outcomes of UVATS versus MVATS were identified, from January 1990 to April 2020. The perioperative, along with the oncologic and long-term survival outcomes, were calculated according to either a fixed or a random effect model, appropriately. The Q statistics and I2 statistic were used to test for heterogeneity among the studies. Results Twenty studies were included, incorporating a total of 1,469 patients treated with UVATS and 3,231 treated with MVATS. The incidence of complications was lower in patients treated with UVATS [OR: 0.76 (95% CI 0.62, 0.93); p = 0.008]. The chest tube duration was significantly lower in the UVATS group (WMD: − 0.63 [95% CI − 1.03, − 0.23]; p = 0.002). Length of hospital stay (L.O.S.) was also lower in the UVATS patient group (WMD: − 0.54 [− 0.94, − 0.13]; p = 0.009), along with postoperative pain [WMD: − 0.57 (95% CI − 0.97, − 0.18); p = 0.004]. No significant differences were found regarding the mean operative time (M.O.T.), mean blood loss, the number of resected lymph nodes, the 30-day mortality, along with the survival at 1 and 3 years postoperatively. Conclusions The present meta-analysis indicates that UVATS is associated with enhanced outcomes in patients undergoing surgery for lung cancer. Well-designed, randomized studies, comparing UVATS to MVATS, are necessary to further assess their long-term clinical outcomes.

Abstract
Introduction Pneumomediastinum defines a condition in which free air is present in the mediastinum usually caused by alveolar rupture resulting from a sudden increase in the intrathoracic pressure and air tracking along the tracheobronchial tree. Case report We present a case of a 16-year-old male patient referred to our department due to persisting odynophagia, and retrosternal chest pain. A performed chest-CT revealed presence of free air in the mediastinum, without evidence of pneumothorax, or subcutaneous emphysema. Under the diagnosis of spontaneous pneumomediastinum (SPM) the treatment included conservative therapy with analgesics, rest, and oxygen. Conclusion SPM is a rare benign condition with nonspecific presenting clinical signs; thus its diagnosis remains mostly one of exclusion. Thorough history-taking, beside radiographic studies, may be the key to confirm the diagnosis.

Abstract
While aneurysms of the internal mammary artery (IMA) complicate occasionally surgical procedures employing median sternotomy, or are associated with direct thoracic trauma, mycotic pseudoaneurysms of the vessel are rarely reported in the literature. We herein report a case of a 22-year-old man who developed a mycotic internal mammary artery pseudoaneurysm secondary to staphylococcal chest wall abscesses and was effectively treated by coil embolization. Additionally, the report provides a brief review focusing on the current state of treatment options for internal mammary artery aneurysms.

Abstract
Background Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis. In this context, the identification of biomarkers regarding the PDAC diagnosis, monitoring, and prognosis is crucial. Objectives The purpose of the current study was to investigate the differential gene expression profile of the chloride intracellular channel (CLIC) gene family network in patients with PDAC, in order to suggest novel biomarkers. Methods In silico techniques were used to construct the interactome of the CLIC gene family, identify the differentially expressed genes (DEGs) in PDAC as compared to healthy controls, and evaluate their potential prognostic role. Results Transcriptomic data of three microarray datasets were included, incorporating 114 tumor and 59 normal pancreatic samples. Twenty DEGs were identified; eight were up-regulated and twelve were downregulated. A molecular signature of seven genes (Chloride Intracellular Channel 1 – CLIC1; Chloride Intracellular Channel 3 – CLIC3; Chloride Intracellular Channel 4 – CLIC4; Ganglioside Induced Differentiation Associated Protein 1 – GDAP1; Ganglioside Induced Differentiation Associated Protein 1 Like 1 – GDAP1L1; Glutathione S-Transferase Pi 1 - GSTP1; Prostaglandin E Synthase 2 – PTGES2) were identified as prognostic markers associated with overall survival. Positive correlations were reported regarding the expression of CLIC1-CLIC3, CLIC4-CLIC5, and CLIC5-CLIC6. Finally, gene set enrichment analysis demonstrated the molecular functions and miRNA families (hsa‐miR‐122, hsa‐miR‐618, hsa‐miR‐425, and hsa‐miR‐518) relevant to the seven prognostic markers. Conclusion These outcomes demonstrate a seven-gene molecular panel that predicts the patients’ prospective survival following pancreatic resection for PDAC.

Abstract
Aquaporins (AQPs) are transmembrane channel proteins that mainly facilitate the water translocation through the plasma cell membrane. For several years these proteins have been extensively examined for their biologic role in health and their potential implication in different diseases. Technological improvements associated with the methods employed to evaluate the functions of the AQPs have provided us with significant new knowledge. In this chapter, we will examine the role of AQPs in health and disease based on the latest currently available evidence.

Abstract
BACKGROUND Rectal Cancer (RC) is a common type of cancer with poor prognosis. The identification of biomarkers regarding RC diagnosis, monitoring, and prognosis is crucial. OBJECTIVES The purpose of the present study was to evaluate the differential expression of the Aquaporin (AQP) gene family network in RC, and the effect of Radiotherapy (RT) on their expression profile, to indicate novel biomarkers and prognostic factors. METHODS We used data mining techniques to construct the network of the AQP-associated genes to determine the Differentially Expressed Genes (DEGs) in RC and in irradiated as compared to nonirradiated RC patients. Furthermore, survival data of The Cancer Genome Atlas (TCGA) were analysed to assess the prognostic role of the DEGs, along with the functional enrichment of gene ontologies and miRNAs related to the DEGs in RC. RESULTS Microarray data of one PubMed GEO dataset was extracted, incorporating 22 RC and 20 normal rectal tissue samples. Eight DEGs were reported. Four DEGs were up-regulated and four downregulated in RC. Correlations were identified among the DEGs. Deming regression analysis was performed in order to demonstrate the equations describing these correlations. One gene (Aquaporin 3) was downregulated in irradiated RC samples compared with non-irradiated samples. The most significantly affected biological pathways and miRNAs were identified by functional enrichment analysis. CONCLUSION The present study demonstrates an eight-gene molecular panel that could facilitate as biomarkers regarding RC patients, which are potential targets of five miRNA families. Finally, our results highlight the effect of radiotherapy on AQPs and the associated pathways in RC.

Abstract
PURPOSE Nodal status represents probably the most important determinant of gastric cancer prognosis. The purpose of the present study was to assess the impact of the primary tumor's T stage on lymph node harvesting after D1 resections for gastric cancer. METHODS Between January 2000 and January 2012, the medical files of patients who presented to our department with the diagnosis of gastric cancer and were submitted to a gastric resection with curative intent were retrospectively reviewed. A total of 134 gastric cancer patients (mean age 67.36±9.64 - 35 females and 99 males) were submitted to a gastrectomy in our department (total or subtotal) with curative intent. The distribution of the tumors within the stomach was as follows: upper third - 37 patients, middle third - 49 patients and lower third - 46 patients. RESULTS Lymph node retrieval was superior in advanced T stage patients (T3,T4a/T4b) compared to their low T stage (T1a/T1b,T2) counterparts (p=0.0008). Similar findings were encountered when the comparison was reduced to the subtotal gastrectomy subgroup (p=0.0047). However, although there was a distinct trend, statistical significance was not reached for the patient group submitted to total gastrectomy (p=0.1088). CONCLUSION The results of the present study seem to add another value i.e. tumor's T stage in the equation of lymph node retrieval in gastric cancer resection specimens. Lymph node retrieval in gastric cancer patients appeared to be dependent to the primary tumors T stage in the given patient sample.

Abstract
BACKGROUND This study aimed to assess the differential gene expression of aquaporin (AQP) gene family interactome in pancreatic ductal adenocarcinoma (PDAC) using data mining techniques to identify novel candidate genes intervening in the pathogenicity of PDAC. METHOD Transcriptome data mining techniques were used in order to construct the interactome of the AQP gene family and to determine which genes members are differentially expressed in PDAC as compared to controls. The same techniques were used in order to evaluate the potential prognostic role of the differentially expressed genes. RESULTS Transcriptome microarray data of four GEO datasets were incorporated, including 142 primary tumor samples and 104 normal pancreatic tissue samples. Twenty differentially expressed genes were identified, of which nineteen were downregulated and one up-regulated. A molecular panel of four genes (Aquaporin 7 - AQP7; Archain 1 - ARCN1; Exocyst Complex Component 3 - EXOC3; Coatomer Protein Complex Subunit Epsilon - COPE) were identified as potential prognostic markers associated with overall survival. CONCLUSION These outcomes should be further assessed in vitro in order to fully understand the role of these genes in the pathophysiological mechanism of PDAC.

Abstract
We aim to review the available literature on patients with morbid obesity treated with banded (BRYGB) or non-banded Roux-en-Y gastric bypass (NBRYGB), in order to compare the clinical outcomes and intraoperative parameters of the two methods. A systematic literature search was performed in PubMed, Cochrane library and Scopus databases, in accordance with the PRISMA guidelines. Eight studies met the inclusion criteria incorporating 3899 patients. This study reveals similar rates of complications, mortality, remission of type 2 diabetes, hypertension, dyslipidaemia, gastroesophageal reflux and obstructive sleep apnoea, along with similar % excess weight loss (%EWL) at 1 and 2 years postoperatively. In contrast, according to an analysis of two eligible studies the BRYGB procedure was associated with increased %EWL at 5 years postoperatively. These results should be interpreted with caution due to the small number of statistical arms and randomized controlled studies. However, the present article represents the best available evidence in the field. Well-designed, randomized controlled studies, comparing BRYGB to NBRYGB, are necessary to further assess their clinical outcomes.

Abstract
BACKGROUND This study aimed to assess the perioperative outcomes of laparoscopic left lateral sectionectomy (LLLS) compared with an open (OLLS) approach. METHOD A systematic literature search was performed in PubMed, Scopus and Cochrane library, in accordance with the PRISMA guidelines. The Odds Ratio (ORs), the weighted mean difference (WMD) and 95% confidence interval (95% CI) were evaluated, by means of Random-Effects model. RESULTS Ten articles met the inclusion criteria and incorporated 2640 patients. This study reveals comparable mean operative time, mean operative margin size and rate of R1 resection between LLLS and OLLS. The intraoperative mean blood loss, mean length of ICU stay, mean hospital stay were significantly increased in the OLLS group (p < 0.05). Complications were assessed according to the Clavien-Dindo classification. The incidence of grade I-II complications was similar between the two groups. The incidence of grade III-V complications was increased in the OLLS group (p = 0.008). The mean perioperative cost was similar between the two techniques. CONCLUSION These outcomes for left lateral sectionectomy suggest that both approaches are feasible and safe. However, the results should be treated with caution given the small number of the included randomized controlled studies and potential for selection bias between the two techniques.
