Abstract
Cardiovascular diseases stand as the predominant global cause of mortality, exerting a profound impact on both life expectancy and its quality. Given their immense public health burden, extensive efforts have been dedicated to comprehending the underlying mechanisms and developing strategies for prevention and treatment. Selenium, a crucial participant in redox reactions, emerges as a notable factor in maintaining myocardial cell homeostasis and influencing the progression of cardiovascular disorders. Some disorders, such as Keshan disease, are directly linked with its environmental deficiency. Nevertheless, the precise extent of its impact on the cardiovascular system remains unclear, marked by contradictory findings in the existing literature. High selenium levels have been associated with an increased risk of developing hypertension, while lower concentrations have been linked to heart failure and atrial fibrillation. Although some trials have shown its potential effectiveness in specific groups of patients, large cohort supplementation attempts have generally yielded unsatisfactory outcomes. Consequently, there persists a significant need for further research aimed at delineating specific patient cohorts and groups of diseases that would benefit from selenium supplementation.

J Cardiothorac Surg 2024; 19:264. [PMID: 38659018 PMCID: PMC11040970 DOI: 10.1186/s13019-024-02761-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 03/30/2024] [Indexed: 04/26/2024] Open
Abstract
INTRODUCTION Postoperative complications pose significant challenges in cardiac surgery and with the evolution of selenium as a potential anti-inflammatory agent, some studies reported its inefficiency. Thus, we conducted our meta-analysis to evaluate the impact of selenium supplementation on cardiac surgery patients. METHODS Different databases such as PubMed, Embase, and Cochrane Library from inception till January 2024 were searched identifying a total of seven randomized-controlled trials involving selenium supplementation after cardiac surgery. Risk ratio (RR) and Mean difference (MD) were calculated with a 95% confidence interval (CI). RESULTS The selenium intervention significantly raised the incidence of Acute Kidney injury (RR 0.76; 95% CI: 0.59, 0.98; P = 0.04) while significantly reducing the duration of hospital stay (MD -1.33; 95% CI: -2.51, -0.16; P = 0.03) and postoperative CRP levels (SMD -0.18; 95% CI: -0.34, -0.02; P = 0.03). The effect of selenium intervention on days spent in ICU (MD -0.01; 95% CI: -0.28, 0.25; P = 0.92), mortality (RR 1.07; 95% CI: 0.84, 1.37; P = 0.57) and incidence of hospital acquired infections (RR 0.98; 95% CI: 0.76, 1.26; P = 0.88) is insignificant. CONCLUSION Selenium supplementation did not significantly reduce major postoperative complications in cardiac surgery patients. However, its ability to modulate inflammation, as reflected in decreased C-reactive protein levels, highlights its potential role in managing the inflammatory response. Future investigations should focus on optimized selenium supplementation strategies in conjunction with other antioxidants to enhance its benefits.

Postoperative hyper-inflammation as a predictor of poor outcomes in patients with acute type A aortic dissection (ATAAD) undergoing surgical repair. J Cardiothorac Surg 2024; 19:138. [PMID: 38504265 PMCID: PMC10949572 DOI: 10.1186/s13019-024-02637-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 03/11/2024] [Indexed: 03/21/2024] Open
Abstract
BACKGROUND Postoperative hyper-inflammation is a frequent event in patients with acute Stanford type A aortic dissection (ATAAD) after surgical repair. This study's objective was to determine which inflammatory biomarkers could be used to make a better formula for identifying postoperative hyper-inflammation, and which risk factors were associated with hyper-inflammation. METHODS A total of 405 patients were enrolled in this study from October 1, 2020 to April 1, 2023. Of these patients, 124 exhibited poor outcomes. In order to investigate the optimal cut-off values for poor outcomes, logistic and receiver operating characteristic analyses were performed on the following parameters on the first postoperative day: procalcitonin (PCT), C-reactive protein (CRP), interleukin-6 (IL-6), and systemic immune-inflammation index (SII). These cut-off points were used to separate the patients into hyper-inflammatory (n = 52) and control (n = 353) groups. Finally, the logistic were used to find the risk factors of hyper-inflammatory. RESULTS PCT, CRP, IL-6, and SII were independent risk factors of poor outcomes in the multivariate logistic model. Cut-off points of these biomarkers were 2.18 ng/ml, 49.76 mg/L, 301.88 pg/ml, 2509.96 × 109/L respectively. These points were used to define postoperative hyper-inflammation (OR 2.97, 95% CI 1.35-6.53, P < 0.01). Cardiopulmonary bypass (CPB) > 180 min, and deep hypothermia circulatory arrest (DHCA) > 40 min were the independent risk factors for hyper-inflammation. CONCLUSIONS PCT > 2.18, CRP > 49.76, IL-6 > 301.88, and SII < 2509.96 could be used to define postoperative hyper-inflammation which increased mortality and morbidity in patients after ATAAD surgery. Based on these findings, we found that CPB > 180 min and DHCA > 40 min were separate risk factors for postoperative hyper-inflammation.

Abstract
Trace elements are essential micronutrients that take part in most antioxidant reactions in the body. In this study, we evaluated the levels of copper, chromium, manganese, selenium, magnesium, zinc, iron, and silicon in adult patients who undergone isolated on-pump coronary artery bypass with the occurrence of postoperative atrial fibrillation, transient renal injury, transient liver injury, and rate of wound infection; 51 adult patients (41 men, 10 women) underwent isolated coronary artery bypass grafting (CABG) under cardiopulmonary bypass. The mean age was 61,9 ± 8,0 years (range 45-82 years). Blood samples were collected preoperatively, postoperative first hour, postoperative first day, and fifth postoperative day for element analysis. Serum levels were determined by an Inductive Coupled Plasma Optical Emission Spectrometer (ICAP 6000). Serum copper, zinc, and selenium values, typically known as strong antioxidant elements in the body, decreased significantly during the first hour and first day of postoperative period compared to the preoperative period (p < 0.05). Also, postoperative atrial fibrillation, transient renal injury, transient liver injury, and rate of wound infection were observed to increase with the decrease in levels of trace elements (p < 0.05). The levels of these elements were observed to return to normal levels during the fifth postoperative day. The levels of trace elements decrease significantly after on-pump coronary artery bypass surgery. Our study results suggest that this could be one of the predisposing factors for increased postoperative atrial fibrillation, transient kidney injury, transient renal injury, and increased rate of wound infections for patients undergoing on-pump coronary artery bypass grafting.

Abstract
Human thioredoxin reductase (TrxR) is a selenoprotein with a central role in cellular redox homeostasis, utilizing a highly reactive and solvent-exposed selenocysteine (Sec) residue in its active site. Pharmacological modulation of TrxR can be obtained with several classes of small compounds showing different mechanisms of action, but most often dependent upon interactions with its Sec residue. The clinical implications of TrxR modulation as mediated by small compounds have been studied in diverse diseases, from rheumatoid arthritis and ischemia to cancer and parasitic infections. The possible involvement of TrxR in these diseases was in some cases serendipitously discovered, by finding that existing clinically used drugs are also TrxR inhibitors. Inhibiting isoforms of human TrxR is, however, not the only strategy for human disease treatment, as some pathogenic parasites also depend upon Sec-containing TrxR variants, including S. mansoni, B. malayi or O. volvulus. Inhibiting parasite TrxR has been shown to selectively kill parasites and can thus become a promising treatment strategy, especially in the context of quickly emerging resistance towards other drugs. Here we have summarized the basis for the targeting of selenoprotein TrxR variants with small molecules for therapeutic purposes in different human disease contexts. We discuss how Sec engagement appears to be an indispensable part of treatment efficacy and how some therapeutically promising compounds have been evaluated in preclinical or clinical studies. Several research questions remain before a wider application of selenoprotein TrxR inhibition as a first-line treatment strategy might be developed. These include further mechanistic studies of downstream effects that may mediate treatment efficacy, identification of isoform-specific enzyme inhibition patterns for some given therapeutic compounds, and the further elucidation of cell-specific effects in disease contexts such as in the tumor microenvironment or in host-parasite interactions, and which of these effects may be dependent upon the specific targeting of Sec in distinct TrxR isoforms.

Abstract
Selenium (Se) is an essential trace element that is necessary for various metabolic processes, including protection against oxidative stress, and proper cardiovascular function. The role of Se in cardiovascular health is generally agreed upon to be essential yet not much has been defined in terms of specific functions. Se deficiency was first associated with Keshan’s Disease, an endemic disease characterized by cardiomyopathy and heart failure. Since then, Se deficiency has been associated with multiple cardiovascular diseases, including myocardial infarction, heart failure, coronary heart disease, and atherosclerosis. Se, through its incorporation into selenoproteins, is vital to maintain optimal cardiovascular health, as selenoproteins are involved in numerous crucial processes, including oxidative stress, redox regulation, thyroid hormone metabolism, and calcium flux, and inadequate Se may disrupt these processes. The present review aims to highlight the importance of Se in cardiovascular health, provide updated information on specific selenoproteins that are prominent for proper cardiovascular function, including how these proteins interact with microRNAs, and discuss the possibility of Se as a potential complemental therapy for prevention or treatment of cardiovascular disease.

Abstract
INTRODUCTION Acute lung injury is common following cardiopulmonary bypass and deep hypothermic circulatory arrest for congenital heart surgery with the most severe injury in the dorsocaudal lung. Metabolomics offers promise in deducing mechanisms of disease states, providing risk stratification, and understanding therapeutic responses in regards to CPB/DHCA related organ injury. OBJECTIVES Using an infant porcine model, we sought to determine the individual and additive effects of CPB/DHCA and lung region on the metabolic fingerprint, metabolic pathways, and individual metabolites in lung tissue. METHODS Twenty-seven infant piglets were divided into two groups: mechanical ventilation + CPB/DHCA (n = 20) and mechanical ventilation only (n = 7). Lung tissue was obtained from dorsocaudal and ventral regions. Targeted analysis of 235 metabolites was performed using HPLC/MS-MS. Data was analyzed using Principal Component Analysis (PCA), Partial Least Square Discriminant Analysis (PLS-DA), ANOVA, and pathway analysis. RESULTS Profound metabolic differences were found in dorsocaudal compared to ventral lung zones by PCA and PLS-DA (R2 = 0.7; Q2 = 0.59; p < 0.0005). While overshadowed by the regional differences, some differences by exposure to CPB/DHCA were seen as well. Seventy-four metabolites differed among groups and pathway analysis revealed 20 differential metabolic pathways. CONCLUSION Our results demonstrate significant metabolic disturbances between dorsocaudal and ventral lung regions during supine mechanical ventilation with or without CPB/DHCA. CPB/DHCA also leads to metabolic differences and may have additive effects to the regional disturbances. Most pathways driving this pathology are involved in energy metabolism and the metabolism of amino acids, carbohydrates, and reduction-oxidation pathways.

Abstract
Here, we addressed the pharmacology and toxicology of synthetic organoselenium compounds and some naturally occurring organoselenium amino acids. The use of selenium as a tool in organic synthesis and as a pharmacological agent goes back to the middle of the nineteenth and the beginning of the twentieth centuries. The rediscovery of ebselen and its investigation in clinical trials have motivated the search for new organoselenium molecules with pharmacological properties. Although ebselen and diselenides have some overlapping pharmacological properties, their molecular targets are not identical. However, they have similar anti-inflammatory and antioxidant activities, possibly, via activation of transcription factors, regulating the expression of antioxidant genes. In short, our knowledge about the pharmacological properties of simple organoselenium compounds is still elusive. However, contrary to our early expectations that they could imitate selenoproteins, organoselenium compounds seem to have non-specific modulatory activation of antioxidant pathways and specific inhibitory effects in some thiol-containing proteins. The thiol-oxidizing properties of organoselenium compounds are considered the molecular basis of their chronic toxicity; however, the acute use of organoselenium compounds as inhibitors of specific thiol-containing enzymes can be of therapeutic significance. In summary, the outcomes of the clinical trials of ebselen as a mimetic of lithium or as an inhibitor of SARS-CoV-2 proteases will be important to the field of organoselenium synthesis. The development of computational techniques that could predict rational modifications in the structure of organoselenium compounds to increase their specificity is required to construct a library of thiol-modifying agents with selectivity toward specific target proteins.

Abstract
Background Cardiac surgery using cardiopulmonary bypass (CPB) frequently provokes a systemic inflammatory response syndrome, which is triggered by TLR4 (Toll‐like receptor 4) and TNF‐α (tumor necrosis factor α) signaling. Here, we investigated whether the adiponectin receptor 1 and 2 agonist AdipoRon modulates CPB‐induced inflammation and cardiac dysfunction. Methods and Results Rats underwent CPB with deep hypothermic circulatory arrest and were finally weaned from the heart‐lung machine. Compared with vehicle, AdipoRon application attenuated the CPB‐induced impairment of mean arterial pressure following deep hypothermic circulatory arrest. During the weaning and postweaning phases, heart rate and mean arterial pressure in all AdipoRon animals (7 of 7) remained stable, while cardiac rhythm was irretrievably lost in 2 of 7 of the vehicle‐treated animals. The AdipoRon‐mediated improvements of cardiocirculatory parameters were accompanied by increased plasma levels of IL (interleukin) 10 and diminished concentrations of lactate and K+. In myocardial tissue, AdipoRon activated AMP‐activated protein kinase (AMPK) while attenuating CPB‐induced degradation of nuclear factor κB inhibitor α (IκBα), upregulation of TNF‐α, IL‐1β, CCL2 (C‐C chemokine ligand 2), nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, and inducible nitric oxide synthase. Correspondingly, in cultured cardiac myocytes, cardiac fibroblasts, and vascular endothelial cells, AdipoRon activated AMPK, upregulated IL‐10, and attenuated activation of nuclear factor κB, as well as upregulation of TNF‐α, IL‐1β, CCL2, NADPH oxidase, and inducible nitric oxide synthase induced by lipopolysaccharide or TNF‐α. In addition, the treatment of cardiac myocytes with the AMPK activator 5‐aminoimidazole‐4‐carboxamide 1‐β‐D‐ribofuranoside resulted in a similar inhibition of lipopolysaccharide‐ and TNF‐α–induced inflammatory cell phenotypes as for AdipoRon. Conclusions Our observations indicate that AdipoRon attenuates CPB‐induced inflammation and impairment of cardiac function through AMPK‐mediated inhibition of proinflammatory TLR4 and TNF‐α signaling in cardiac cells and upregulation of immunosuppressive IL‐10.

Abstract
Non-pharmacological treatments have always been considered important in the management of Chronic Coronary Syndromes. Nutraceuticals ("Nutrition" + "Pharmaceutical") could fall both under the definition of non-pharmacological treatment and pharmacological one or, probably more correctly, in the middle of these two kinds of therapies. However, the word "nutraceuticals" never appears in the latest guidelines on this issue. This is probably determined by the fact that evidences on this topic are scarce and most of the published articles are based on preclinical data while translational experiences are available only for some molecules. In this review we will focus on nutraceutical strategies that act on the ischemic myocardium itself and not only on the cardiovascular risk factors. As demonstrated by the important number of papers published in recent years, this is an evolving topic and evaluated substances principally act on two mechanisms (cardiac energetics and ischemia-reperfusion damage) that will be also reviewed.

Abstract
Selenium is a trace element that provides protection against cellular damage and death. Previous research using several types of cells identified anti-oxidant, anti-inflammatory, and anti-apoptotic effects for selenium. One of the diseases related to selenium is cardiovascular disease, as low selenium intake has been linked to cardiomyopathy. However, the mechanism of the cardioprotective effects of selenium is not thoroughly understood. Several studies supported the possible effects of selenium on heart cell survival. In this review, we analyzed recent research (2015-2020) on the roles and mechanism of action of selenium in cell survival and its cardioprotective effects. Furthermore, the prevention of apoptosis through both intrinsic and extrinsic pathways is discussed in this review. Signalling pathways that regulate cell survival such as the p-AMPK, poly (ADP-ribose) polymerase-1, nuclear factor-erythroid 2-related factor-2, AKT/PI3K, and STAT pathways are involved in the protective effects of selenium. In addition, signaling pathways that affect heart cell survival include the AKT and STAT pathways. It also affects autophagy through the PPAR-γ pathway. These findings should facilitate further research on the cardioprotective effects of selenium.

Abstract
Background Many studies have reported that dexmedetomidine protects organs from ischemia/reperfusion-induced injury. However, the mechanism of this protective effect remains inconclusive. Methods Rats were randomly divided into 6 groups (n=8). Rats in the sham group were not subjected to cardiopulmonary bypass (CPB) while rats in the other groups underwent CPB for 2 h. Groups L and H received a low and a high dose of dexmedetomidine, respectively. Rats in group AG490 received 10 mg/kg of the Janus kinase 2 (JAK2) inhibitor, AG490, 30 min before anesthesia. Plasma levels of the inflammatory cytokines, interleukin (IL)-6 and IL-10, were measured by enzyme-linked immunosorbent (ELISA), and the apoptosis rate of myocardial cells, the expression of JAK2 and signal transducer and activator of transcription (STAT)3 mRNA, and the protein expression of JAK2, STAT3, pJAK2, pSTAT3, and caspase-3 were analyzed in myocardial tissues by real-time quantitative polymerase chain reaction (qRT-PCR), western blotting, and immunohistochemistry. Results We observed that, in both group L and group H, the level of IL-6 decreased (P<0.05), and the apoptosis rate of myocardial cells were reduced (P<0.05) compared to those in the CPB group. Moreover, qRT-PCR results revealed that dexmedetomidine administration reduced the expression of JAK2 and STAT3 mRNA (P<0.05); pJAK2 and pSTAT3 (P<0.05) protein levels were also reduced as assessed by western blotting and immunohistochemistry (P<0.05). Conclusions Dexmedetomidine treatment reduced CPB-related myocardial injury by inhibiting inflammatory reactions and myocardial apoptosis, and can be a potential therapy in CPB-related surgery.

Abstract
OBJECTIVES To explore whether coronary endarterectomy (CE) sites have obvious impacts on the clinical outcomes and graft patency in off-pump coronary artery bypass (OPCAB). METHODS The patients who underwent OPCAB with CE in our unit between January 2009 and December 2016 were included. The patients and the grafts were grouped according to the CE sites. The primary end points were mid-term main adverse cardiovascular and cerebrovascular events. RESULTS In total, 290 patients who underwent OPCAB with CE were included. CE of the left anterior descending artery (LAD), left circumflex artery and the right coronary artery was performed in 46, 30 and 194 patients, respectively. There were 60, 42 and 217 grafts anastomosed to LAD-CE, left circumflex artery-CE and right coronary artery-CE sites in 290 patients. CE was not performed in the 20 patients requiring multivessel CE. There was no significant difference in perioperative outcomes. The average follow-up time was 51 months (12-103 months). There was no significant difference in mid-term death, main adverse cardiovascular and cerebrovascular events, myocardial infarction (MI), stroke, Canadian Cardiovascular Classification for angina class and 1-year graft patency among the 3 groups. However, the rate of New York Heart Association (NYHA) class III or IV (LAD vs left circumflex artery: 59% vs 25%, P = 0.011; LAD vs right coronary artery: 59% vs 27%, P < 0.001) was higher in the LAD group than in the other groups. These results were consistent with the Kaplan-Meier curves of freedom from the adverse events. CONCLUSIONS CE sites had no obvious impact on mid-term death, main adverse cardiovascular and cerebrovascular events, MI, stroke, Canadian Cardiovascular Classification for angina class and 1-year graft patency in patients who underwent OPCAB with CE. The patients undergoing LAD-CE had higher rates of NYHA class III or IV.

Abstract
BACKGROUND Apoptosis is a cellular mechanism contributing to cardiac surgery using cardiopulmonary bypass (CPB)-induced lung injury. The ubiquitous PI3K/Akt pathway regulates proliferation, apoptosis and differentiation by controlling a broad range of target proteins including NF-κB and GSK-3β. The roles of the PI3K/Akt/NF-κB and PI3K/Akt/GSK-3β pathways in CPB-related lung injury are unclear. METHODS Seventy-two male Sprague-Dawley rats were assigned into sham, CPB, Wortmannin (Wtn) and insulin-like growth factor-I (IGF-I) groups (n = 18, each). Six subjects per group were evaluated at each of three time points: Prior to CPB (T1); opening of the left hilus pulmonis (T2); and 90 min after CPB (T3). Arterial blood specimens were obtained at each time point to test respiratory and oxygenation indices. Left lung tissues were processed for H&E and TUNEL staining. Western blot was employed to evaluate protein levels and activities of Akt, phospho-Akt (p-Akt), GSK-3β, phospho-GSK-3β (p-GSK-3β) and nuclear NF-κB. RESULTS Lung ischemia/reperfusion and CPB caused notable lung injury, as evidenced by lung functional decline and pathological deterioration, accompanied by increases in apoptosis and expression levels of p-Akt, p-GSK-3β and nuclear NF-κB in lungs (all P < 0.05 vs. Sham). At T3, Wtn-treated CPB subjects showed worsened lung function and pathological lung structures, as well as apoptosis in lungs (all P < 0.05 vs. CPB); additionally, Wtn inhibited Akt phosphorylation and slightly, but significantly increased expression of nuclear NF-κB (both P < 0.001 vs. CPB). Conversely, treatment of subjects with IGF-I increased Akt phosphorylation (P < 0.001 vs. CPB), inhibited expression of nuclear NF-κB (P = 0.008 vs. CPB), improved lung function and tissue morphology (both P < 0.05 vs. CPB), and reduced apoptosis in lungs (P < 0.001 vs. CPB). Neither Wtn nor IGF-I did alter GSK-3β phosphorylation levels (P = 0.836 and P = 0.669 vs. CPB, respectively). CONCLUSION The PI3K/Akt/NF-κB pathway played a role in CPB-related lung injury, possibly through mediating apoptosis in lungs. GSK-3β, a signaling effector that also participated in CPB-induced apoptosis in lungs, but was not regulated by the PI3K/Akt pathway in this context.

Abstract
Cardiopulmonary bypass (CPB) constitutes one of the primary methodologies pertaining to cardiac surgery. However, this form of surgery can cause damage to the body. Many studies have reported that dexmedetomidine confers cerebral protection. In this study, we aimed to investigate the effect and mechanism of dexmedetomidine on neuronal apoptosis caused by CPB. Here, rats were treated with different doses of dexmedetomidine by intravenous infusion 2 hours after CPB. We observed that dexmedetomidine treatment to rats reduces the S100β, NSE levels in plasma, and neuronal apoptosis following CPB in a dose-dependent manner. Furthermore, we observed that the beneficial effect of dexmedetomidine treatment following CPB was associated with a reduction in IL6, an inflammatory cytokine in plasma and cortex. Our results suggest that dexmedetomidine provides neuroprotective effects by inhibiting inflammation and reducing neuronal apoptosis. There was a correlation between the protective effect on the brain and the dose of dexmedetomidine. In addition, dexmedetomidine administration inhibits phosphorylation of JAK2 and STAT3 proteins in the hippocampus of rats 2 hours after CPB. Therefore, we speculate that the JAK2–STAT3 pathway plays an important role in the neuroprotective effects of dexmedetomidine following brain injury induced by CPB.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a major cause of death and debility following trauma. The initial brain tissue insult is worsened by secondary reactive responses including oxidative stress reactions, inflammatory changes and subsequent permanent neurologic deficits. Effective agents to improve functional outcome and survival following TBI are scarce. Selenium is an antioxidant which has shown to reduce oxidative stress. This study examines the effect of intravenous selenium (Selenase®) treatment in patients with severe TBI on functional outcome and survival in a prospective study design. METHODS Patients sustaining TBI were prospectively identified during a 12-month period at an academic urban trauma center. Study inclusion criteria applied were: age ≥18 years, blunt injury mechanism and admission to neurosurgical intensive care unit (NICU). Early deaths (≤48h) and patients suffering extracranial injuries requiring invasive interventions or surgery were excluded. All consecutive admissions during a six-month period were administered intravenous Selenase® for a maximum 10-day period and constituted cases. Patient demographics and outcomes up to six-months post-discharge were collected for analysis. RESULTS A total of 307 patients met inclusion criteria of which 125 were administered Selenase®. Stepwise Poisson regression analysis identified five common predictors of poor functional outcome and in-hospital mortality: GCS ≤8, age ≥55 years, hypotension at admission, high Rotterdam score and invasive neurosurgical intervention. Selenase® significantly reduced the risk of unfavourable functional outcomes, defined as GOS-E ≤4, at both discharge (adjusted RR 0.69, 95% CI 0.51-0.92, p=0.012) and at six months follow-up (adjusted RR 0.61, 95% CI 0.44-0.83, p=0.002). Following adjustment for significant group differences similar results were seen for functional outcome. Selenase® did not improve survival (adjusted RR 1.12, 95% CI 0.62-2.02, p=0.709). CONCLUSION Intravenous Selenase® treatment demonstrates a significant improvement in functional neurologic outcome. This effect is sustained at six months following discharge.

Abstract
Objective Numerous studies in animals and humans have demonstrated that inflammatory mediators such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-8 play a role in cardiopulmonary bypass (CPB), which might affect surgical outcomes. Plasma mitochondrial DNA (mtDNA), a recently discovered pro-inflammatory agent, is released by cells upon insult. This study aimed to detect changes in plasma mtDNA levels at different time points after infantile CPB and explore its potential association with inflammatory mediators. Methods In the present study, we analyzed the perioperative plasma mtDNA and inflammatory cytokine levels of 48 infants undergoing ventricular septal defect closure. Blood samples were collected before aortic cross-clamping (T1), at the end of CPB (T2), and 6 h (T3), 12 h (T4), and 24 h (T5) post-CPB. Reverse transcription–polymerase chain reaction and specific enzyme-linked immunosorbent assay were used to quantify the plasma mtDNA and inflammatory cytokines, respectively. Bivariate correlation analysis was used to determine the correlations between plasma mtDNA and inflammatory cytokines. Results Plasma mtDNA levels increased at T2 and peaked at T3. Significant positive correlations were found between peak plasma mtDNA (at T3) and several inflammatory biomarkers, including IL-6 (at T3) (r = 0.62, P < 0.001), IL-8 (at T2) (r = 0.53, P < 0.001), and TNF-α (at T3) (r = 0.61, P < 0.001). Conclusion Here we report that mtDNA may participate in a systemic inflammatory response to CPB.
