RESUMEN
BACKGROUND: Different techniques have been described for esophagogastric anastomosis. Over the past decades, surgeons have been improving anastomotic techniques with a gradual shift from hand-sewn to stapled anastomosis. Nowadays, circular-stapled (CS) and linear-stapled (LS) anastomosis are commonly used during esophagectomy. METHODS: PubMed, MEDLINE, Scopus, and Web of Science were searched up to June 2022. The included studies evaluated short-term outcomes for LS vs. CS anastomosis in patients undergoing esophagectomy for cancer. Primary outcomes were anastomotic leak (AL) and stricture (AS). Risk ratio (RR) and standardized mean difference (SMD) were used as pooled effect size measures whereas 95% confidence intervals (95%CI) were used to assess relative inference. RESULTS: Eighteen studies (2861 patients) were included. Overall, 1371 (47.9%) underwent CS while 1490 (52.1%) LS. Compared to CS, LS was associated with a significantly reduced RR for AL (RR = 0.70; 95% CI 0.54-0.91; p < 0.01) and AS (RR = 0.32; 95% CI 0.20-0.51; p < 0.0001). Stratified subgroup analysis according to the level of anastomosis (cervical and thoracic) still shows a tendency toward reduced risk for LS. No differences were found for pneumonia (RR 0.78; p = 0.12), reflux esophagitis (RR 0.74; p = 0.36), operative time (SMD -0.25; p = 0.16), hospital length of stay (SMD 0.13; p = 0.51), and 30-day mortality (RR 1.26; p = 0.42). CONCLUSIONS: LS anastomosis seems associated with a tendency toward a reduced risk for AL and AS. Although surgeon's own training and experience might direct the choice of esophagogastric anastomosis, our meta-analysis encourages the use of LS anastomosis.

OBJECTIVES: Postoperative hemorrhage in cardiac surgery is a significant cause of morbidity and mortality. Standard laboratory tests fail as predictors for bleeding in the surgical setting. The use of viscoelastic (VE) hemostatic assays thromboelastography (TEG) and rotational thromboelastometry (ROTEM) could be an advantage in patients undergoing cardiac surgery. The objective of this meta-analysis was to analyze the effects (benefits and harms) of VE-guided transfusion practice in cardiac surgery patients. DESIGN: A meta-analysis of randomized trials. SETTING: For this study, PubMed, EMBASE, Scopus, and the Cochrane Collaboration database were searched, and only randomized controlled trials were included. A systematic review and meta-analysis were performed in accordance with the standards set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, using a random-effects model. PARTICIPANTS: The study comprised adult cardiac surgery patients. INTERVENTIONS: VE-hemostatic assays transfusion algorithm compared with transfusion algorithms based on clinicians' discretion. MEASUREMENTS AND MAIN RESULTS: Seven comparative randomized controlled trials were considered, including a total of 1,035 patients (522 patients in whom a TEG- or ROTEM-based transfusion algorithm was used). In patients treated according to VE-guided algorithms, red blood cell (odds ratio 0.61; 95% confidence interval [CI]: 0.37-0.99; p: 0.04; I2: 66%) and fresh frozen plasma transfusions (risk difference 0.22; 95% CI: 0.11-0.33; p < 0.0001; I2: 79%) use was reduced; platelets transfusion was not reduced (odds ratio 0.61; 95% CI: 0.32-1.15; p: 0.12; I2 74%). CONCLUSIONS: This study demonstrated that the use of VE assays in cardiac surgical patients is effective in reducing allogenic blood products exposure, postoperative bleeding at 12 and 24 hours after surgery, and the need for redo surgery unrelated to surgical bleeding.

Epigenetic mechanisms including deoxyribonucleic acid (DNA) methylation, histone modifications (eg, histone acetylation), and microribonucleic acids (miRNAs) have gained much scientific interest in the last decade as regulators of genes expression and cellular function. Epigenetic control is involved in the modulation of inflammation and immunity, and its dysregulation can contribute to cell damage and organ dysfunction. There is growing evidence that epigenetic changes can contribute to the development of multiorgan dysfunction syndrome (MODS), a leading cause of mortality in the intensive care unit (ICU). DNA hypermethylation, histone deacetylation, and miRNA dysregulation can influence cytokine and immune cell expression and promote endothelial dysfunction, apoptosis, and end-organ injury, contributing to the development of MODS after a critical injury. Epigenetics processes, particularly miRNAs, are emerging as potential biomarkers of severity of disease, organ damage, and prognostic factors in critical illness. Targeting epigenetics modifications can represent a novel therapeutic approach in critical care. Inhibitors of histone deacetylases (HDCAIs) with anti-inflammatory and antiapoptotic activities represent the first class of drugs that reverse epigenetics modifications with human application. Further studies are required to acquire a complete knowledge of epigenetics processes, full understanding of their individual variability, to expand their use as accurate and reliable biomarkers and as safe target to prevent or attenuate MODS in critical disease.

Cooperation activity in training programmes promoted by IRCCS Policlinico San Donato and Bambini Cardiopatici nel Mondo Association is a model of cooperation between people as an alternative intervention in promoting the right to healthcare, especially offering programmes of training and medical care on cardiovascular and congenital heart disease. This new strategy, implemented in several developing countries, has absolutely contributed to the improvement of the medical services concerning the diagnostic and surgical approach in the treatment of paediatric and adult cardiovascular disease. To strengthen this kind of activity, both IRCCS Policlinico San Donato and Bambini Cardiopatici nel Mondo have introduced a global perspective aiming at the realization of surgical missions 'in situ', building new cardiac surgery units in collaboration with the local partners, which are mainly university hospitals. They, furthermore, support financially the scholarship and accommodation in favour of medical and paramedical staff.
RESUMEN
BACKGROUND: Little is known of the prognostic significance of mitral regurgitation (MR) on transcatheter aortic valve replacement (TAVR), the impact of TAVR on MR severity, and the variables associated with possible post-TAVR improvement in MR. We evaluated these issues in a multicenter registry of patients undergoing CoreValve Revalving System-TAVR. METHODS AND RESULTS: Among 1007 consecutive patients, 670 (66.5%), 243 (24.1%), and 94 (9.3%) presented with no/mild, moderate, and severe MR, respectively. At 1 month after TAVR, patients with severe or moderate MR showed comparable mortality rates (odds ratio, 1.1; 95% confidence interval [95% CI], 0.7-1.55; P=0.2), but both were significantly higher compared with patients with mild/no MR (odds ratio, 2.2; 95% CI, 1.78-3.28; P<0.001; and odds ratio, 1.9; 95% CI, 1.1-3.3; P=0.02, respectively). One-year mortality was also similar between patients with severe and those with moderate MR (hazard ratio, 1.4; 95% CI, 0.94-2.4; P=0.06) and still significantly higher compared with patients with mild/no MR (hazard ratio, 1.7; 95% CI, 1.2-3.41; P<0.001; and hazard ratio, 1.4; 95% CI, 1.2-2.2; P=0.03, respectively). Severe pulmonary hypertension, atrial fibrillation, and MR more than mild, but not an improvement of ≥1 grade in MR severity, were independent predictors of mortality at 1 year. At 1 year, an improved MR was observed in 47% and 35% of patients with severe and moderate MR, respectively. The rate of low implantation was consistent across groups with improved, unchanged, or worsened MR. A functional type of MR and the absence of severe pulmonary hypertension and atrial fibrillation independently predicted the improvement in MR severity. CONCLUSIONS: Baseline MR greater than mild is associated with higher mortality after CoreValve Revalving System-TAVR. A significant improvement in MR was more likely in patients with functional MR and without severe pulmonary hypertension or atrial fibrillation. The improvement in MR did not independently predict mortality.

Symptomatic aortic valve stenosis (AS) and abdominal aortic aneurysm (AAA) are critical clinical conditions, increasingly more prevalent with aging of the population. Calcific aortic stenosis is the most common structural cardiac disease in the elderly population, and medical management of severe aortic stenosis of the elderly population is associated with poor outcomes as compared to surgical treatment. Transcatheter aortic valve replacement (TAVR) is a treatment of choice in inoperable, often elderly, patients with symptomatic severe AS and in intermediate-to-high surgical risk patients. It is not yet clarified the incidence of AAA and its impact on procedural and clinical outcomes among patients undergoing TAVR. It is known that after AS resolution with aortic valve replacement or TAVR there is an increase in blood pressure that increases the risk of dissection or abdominal aortic aneurysm rupture if AAA repair is delayed. The purpose of this report is to describe the anatomical details and technical and procedural considerations when proposing totally endovascular strategies dedicated to the treatment of patients with AS and AAA.

Primary cardiac tumours are rarely found and have an incidence of 0.3% in all open-heart surgeries. Among those, approximately 70% are myxomas, most of them in the left atrium. The reported incidence of cardiac tumours in autopsy series is 0.001-0.28%. Right atrial myxomas are uncommon, but when present they often originate from the interatrial septum, and conduction disturbances are rarely noted as an accompanying feature in this condition. We report the case of an 18-year-old boy with a myxoma in both left and right atrium associated with atrioventricular dissociation.

Despite the alarming and growing burden of cardiovascular diseases in sub-Saharan Africa (SSA), there is still a huge lack of specialised institutions in the region with a mean of one cardio-surgical unit for 33 million inhabitants. Despite the numerous efforts from humanitarian organisations made in recent years, the setting up of cardio-surgical units in the region remains challenging with regards to long-term sustainability. Indeed, besides the lack of financial resources, the insufficient local expertise in addition to the inadequate health infrastructure, unpredictable threats from external factors such as recurrent conflicts and humanitarian crises are still major concerns in an environment characterised by endemic socio-political instability. In Cameroon, located in the North West Anglophone region at 500 km from the capital, the cardiac centre of Shisong (CCS) is currently the lone cardio-surgical institution of the country. Fruit of a joint initiative of two Italian Non-governmental organisations namely, Bambini Cardiopatici nel Mondo (ABCnM) and Cuore Fratello (CF), and a local religious partner, the Tertiary Sisters of Saint Francis (TSSF), the CCS was faced with in the middle of a socio-political crisis that led to the urgent need of revision of the cardio-surgical project. The current paper reviews the impact of the ongoing socio-political crisis on the CCS over the past 3 years, in terms of clinical activities, staff perspectives, and long-term sustainability.
RESUMEN
BACKGROUND: In the setting of esophageal squamous cell carcinoma, controversy exists regarding the optimal extent of lymphadenectomy, while conclusive evidence regarding the advantages of 3-field versus 2-field lymphadenectomy remains controversial. The purpose of the present meta-analysis was to investigate the effect of 3-field lymphadenectomy versus 2-field lymphadenectomy on overall survival. METHODS: Systematic review and meta-analyses were computed to compare 3-field lymphadenectomy versus 2-field lymphadenectomy in the setting of esophageal squamous cell carcinoma. Risk ratio, weighted mean difference, hazard ratio, and restricted mean survival time difference were used as pooled effect size measures. RESULTS: Fourteen studies (3,431 patients) were included. Overall, 1,664 (48.8%) patients underwent 3-field lymphadenectomy, and 1,767 (51.5%) underwent 2-field lymphadenectomy. Three-field lymphadenectomy was associated with a significantly improved 5-year overall survival (hazard ratio: 0.80; 95% confidence interval 0.71-0.90; P < .001). The restricted mean survival time difference showed a statistically significant difference between 3-field lymphadenectomy versus 2-field lymphadenectomy up to 48 months (1.6 months; P = .04), however, no significant differences were found at 60-month follow-up (1.2 months; P = .14). No significant differences were found in term of postoperative mortality, anastomotic leak, pulmonary complications, chylothorax, and recurrent nerve palsy. CONCLUSION: For resectable esophageal squamous cell carcinoma, 3-field lymphadenectomy seems associated with a slight trend toward improved 5-year overall survival; however, its clinical benefit remains limited.

OBJECTIVES: To measure the effects of fenoldopam mesylate infusion on splanchnic blood flow in patients undergoing myocardial revascularization with cardiopulmonary bypass. DESIGN: An experimental observational study. SETTING: A single-institution community hospital. PARTICIPANTS: Eighteen patients undergoing on-pump coronary artery bypass graft surgery. INTERVENTIONS: Fenoldopam mesylate infusion (0.1 µg/kg/min). MEASUREMENTS AND MAIN RESULTS: Blood flow through the celiac artery, superior mesenteric artery, portal vein and hepatic artery were assessed by means of Doppler measurements. The main hemodynamic variables were measured using echocardiography. The infusion of fenoldopam significantly increased the blood flow through both celiac and superior mesenteric arteries by decreasing vascular resistance. The percentage of cardiac output directed to these 2 vessels increased significantly; the increase through the superior mesenteric artery was greater compared with the celiac artery. Portal vein and hepatic artery blood flow also consistently increased. No significant variations were observed with respect to hemodynamic variables. CONCLUSIONS: The infusion of fenoldopam increased the flow through the celiac artery and superior mesenteric artery; the effect was higher for the latter. These changes did not affect the hemodynamic variables.

Advanced heart failure (HF) represents a public health priority due to the increase of affected patients and the meaningful mortality. Durable mechanical circulatory support (MCS) and heart transplantation (HTx) are unique therapies for end-stage HF (ESHF), with positive early and long-term outcomes. The patients who underwent HTx have a 1-y survival of 91% and a median survival of 12-13 y, whereas the median survival of ESHF is <12 mo. Short-term MCS with veno-arterial extracorporeal membrane oxygenation (VA ECMO) can be used as a bridge to transplantation strategy. Patients bridged with VA ECMO have significantly lower survival in comparison with non-MCS bridged and left ventricular assist device-bridged patients. VA ECMO represents an effective, and sometimes unique, system to obtain rapid hemodynamic stabilization, but possible negative effects on patients' outcomes after HTx must be considered. Here, we discuss the use of VA ECMO as bridge to transplantation.
RESUMEN
A steadying increase of cancer survivors has been observed as a consequence of more effective therapies. However, chemotherapy regimens are often associated with significant toxicity, and cardiac damage emerges as a prominent clinical issue. Many mechanisms sustain chemotherapy-induced cardiac toxicity: direct myocyte damage, arrhythmia induction, coronary vasospasm, and accelerated atherosclerosis. Anthracyclines are the most studied cardiotoxic drugs and represent a clinical model for cardiac damage induced by chemotherapy. In patients suffering from advanced heart failure (HF) because of chemotherapy-related cardiomyopathy, when refractory to optimal medical therapy, mechanical circulatory support or heart transplantation represents an effective treatment. Here, the main mechanisms of cardiac toxicity induced by cancer therapies are analyzed, with a focus on patients requiring intensive care unit (ICU) admission during the course of the disease because of acute cardiac toxicity, takotsubo syndrome, and acute-on-chronic HF in patients suffering from chemotherapy-induced cardiomyopathy. In a subset of patients, cardiac toxicity can be acute and life-threatening, leading to overt cardiogenic shock. The management of critically ill cancer patients poses a unique challenge and requires a multidisciplinary approach. Moreover, no etiologic therapy is available, and only supportive measures can be implemented.
RESUMEN
We describe the case of a 58-year-old man presenting with myocardial infarction complicated by cardiogenic shock, treated with Impella CP which was escalated to an axillary 5.0 due to lack of cardiac recovery. Weaning from Impella 5.0 failed, and the patient was evaluated for heart transplantation (HTx) or left ventricular assist device (LVAD). HTx was excluded because of a rectal adenocarcinoma. The patient underwent colorectal surgery while on Impella. Perioperative course was uneventful. After 61 days of Impella, when the LVAD implantation was scheduled, the patient died due to K. pneumoniae infection.

OBJECTIVE: The purpose of this study was to evaluate the effect of 0.1 microg/kg/min of fenoldopam mesylate on renal flow and central hemodynamics measured by echocardiography in hemodynamically stable patients with preserved renal function undergoing cardiac surgery. DESIGN: Experimental observational study. SETTING: Single-institutional community hospital study. PARTICIPANTS: Thirty patients undergoing cardiac surgery. INTERVENTION: Fenoldopam mesylate infusion (0.1 microg/kg/min) in patients undergoing cardiopulmonary bypass. MEASUREMENTS AND MAIN RESULTS: Doppler measurements of renal blood flow and echocardiographic hemodynamic determinations after Doppler echocardiography measured flux velocities of the main, segmental, and interlobar and interlobular right renal arteries. The authors calculated the resistive index of all the renal segments studied. Moreover, the authors measured the flux of the main renal artery and its diameter as well as the main hemodynamic variables. All the measurements were performed in the intensive care unit setting at baseline and 20 minutes after the infusion of 0.1 microg/kg/min of fenoldopam mesylate. Fenoldopam mesylate infusion significantly increased blood flow in all renal compartments, thus improving the resistive index. The study showed that fenoldopam mesylate infusion does not induce any significant change of the heart rate or arterial pressure, cardiac output, preload, or wall stress. CONCLUSIONS: In hemodynamically stable cardiac surgery patients with preserved renal function, an infusion of 0.1 microg/kg/min of fenoldopam mesylate has no influence on systemic hemodynamics while increasing renal blood flow.

The coronavirus disease 2019 (COVID-19) pandemic has profoundly affected all health care professionals. The outbreak required a thorough reorganization of the Italian regional local health care system to preserve resources such as ventilators, beds in intensive care units and surgical and anaesthesiological staff. Levels of priority were created, together with a rigorous triage procedure for patients with COVID-19, which led to postponement of all elective procedures. Urgent cases were discussed with the local heart team and percutaneous approaches were selected as the first treatment option to reduce hospital stay. COVID-19 and COVID-19-free pathways were created, including adequate preparation of the operating room, management of anaesthesiological procedures, transportation of patients and disinfection. It was determined that patients with chronic diseases were at increased risk of adverse outcomes. Systemic inflammation, cytokine storm and hypercoagulability associated with COVID-19 increased the risk of heart failure and cardiac death. In this regard, the early use of extracorporeal membrane oxygenation could be life-saving in patients with severe forms of acute respiratory distress syndrome or refractory heart failure. The goal of this paper was to report the Italian experience during the COVID-19 pandemic in the setting of cardiovascular surgery.

The inappropriate use of antibiotics in man is driving to insurgence of pathogenic bacteria resistant to multiple drugs (MDR) representing a challenge in critical illness. The interaction of MDR bacteria with host cells can guide molecular perturbations of host transcriptional programmes involving epigenetic-sensitive mechanisms, mainly DNA methylation, histone modifications, and non-coding RNAs leading to pathogen survival. Clinical evidence of epigenetic manipulation from MDR bacteria mainly arises from Mycobacterium tuberculosis as well as Helicobacter pylori, Escherichia coli, Listeria monocytogenes, Pseudomonas aeruginosa, and Legionella pneumophila infection suggesting possible biomarkers of disease. For example, DNA hypermethylation of E-cadherin (CDH1), upstream transcription factor 1/2 (USF1/2), WW domain containing oxidoreductase (WWOX), and mutL homolog 1 (MLH1) genes in gastric mucosa is correlated with malignancy suggesting useful biomarkers of early disease state. Moreover, upregulated circulating miR-361-5p, miR-889, miR-576-3p may be useful biomarkers to discriminate tuberculosis patients. Moreover, Listeria monocytogenes can indirectly induce H3 hyperacetylation leading to inflammation in human endothelial cells whereas Pseudomonas aeruginosa excretes QS 2-AA to directly induce H3 deacetylation leading to bacterial persistence in human monocytes. Remarkably, epigenetic-sensitive drugs may aid to counteract MDR in clinical setting. Trichostatin A, a histone deacetyltransferase inhibitor (HDACi), leads to AMP ß-defensin 2 (HBD2) gene up-regulation in human epithelial cells suggesting a useful 'epi-therapy' for Escherichia coli-induced intestinal diseases. We update on the most current clinical studies focusing on epigenetic changes involved in bacterial-host interactions and their putative role as biomarkers or drug targets to improve precision medicine and personalized therapy in critical illness and transplantation setting.

Several studies have been published describing the clinical and radiographic findings of coronavirus disease 2019-related pneumonia. Therefore, there is currently a lack of pathologic data on its effects in intubated patients. Pneumothorax may occur rarely and results from a combination of fibrotic parenchyma and prolonged high-pressure ventilation. Chest drainage represents first-line treatment. However, in cases of persistent pneumothorax, thoracoscopy and bleb resection may be feasible options to reduce air leak and improve ventilation. This report describes the cases of 2 patients with coronavirus disease 2019 who were successfully treated with thoracoscopy, bleb resection, and pleurectomy for persistent pneumothorax.

RATIONALE: Although there have been several studies describing clinical and radiographic features about the novel coronavirus (COVID-19) infection, there is a lack of pathologic data conducted on biopsies or autopsies. PATIENT CONCERNS: A 56-year-old and a 70-year-old men with fever, cough, and respiratory fatigue were admitted to the intensive care unit and intubated for respiratory distress. DIAGNOSIS: The nasopharyngeal swab was positive for COVID-19 and the chest Computed Tomography (CT) scan showed the presence of peripheral and bilateral ground-glass opacities. INTERVENTIONS: Both patients developed pneumothoraces after intubation and was managed with chest tube. Due to persistent air leak, thoracoscopies with blebs resection and pleurectomies were performed on 23rd and 16th days from symptoms onset. OUTCOMES: The procedures were successful with no evidence of postoperative air-leak, with respiratory improvement. Pathological specimens were analyzed with evidence of diffuse alveolar septum disruption, interstitium thickness, and infiltration of inflammatory cells with diffuse endothelial dysfunction and hemorrhagic thrombosis. LESSONS: Despite well-known pulmonary damages induced by the COVID-19, the late-phase histological changes include diffused peripheral vessels endothelial hyperplasia, in toto muscular wall thickening, and intravascular hemorrhagic thrombosis.

BACKGROUND: Postoperative leak and intra-abdominal infections are common after bariatric surgery with a significant impact on perioperative outcomes, hospital length of stay, and readmission rates. In the era of enhanced recovery programs, with patients being discharged from the hospital 24-36 h after surgery and potentially before developing any complications, an early indicator of postoperative complications may be decisive. The aim of this study was to evaluate the predictive role of the C-reactive protein (CRP) in the early diagnosis of complications in patients undergoing laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: PubMed, Embase, and Web of Science databases were consulted. A systematic review and a fully Bayesian meta-analysis were conducted. RESULTS: Seven studies met the inclusion criteria for a total of 1401 patients. Overall, 57.7% underwent LSG while 42.3% underwent LRYGB. The pooled prevalence of postoperative complications was 9.8% (95% CI = 5-16%). The estimated pooled CRP cut-off value on postoperative day 1 (POD1) was 6.1 mg/dl with a significant diagnostic accuracy and a pooled area under the curve of 0.92 (95% credible interval (CrI) 0.73-0.98). The positive and negative likelihood ratios were 13.6 (95% CrI 8.40-15.9) and 0.16 (95% CrI 0.04-0.31), respectively. CONCLUSION: A CRP value lower than the derived cut-off of 6.1 mg/dl on POD1, combined with reassuring clinical signs, could be useful to rule out early postoperative leak and complications after LSG and LRYGB. In the context of enhanced recovery after surgery protocols, the integration of a CRP-based diagnostic algorithm as an additional complementary instrument may be valuable to reduce cost and improve outcomes and patient care.
