Abstract
Sepsis is a life-threatening condition manifested by organ dysfunction caused by a dysregulated host response to infection. Lung, brain, liver, kidney, and heart are among the affected organs. Sepsis-induced cardiomyopathy is a common cause of death among septic patients. Sepsis-induced cardiomyopathy is characterized by an acute and reversible significant decline in biventricular both systolic and diastolic function. This is accompanied by left ventricular dilatation. The pathogenesis underlying sepsis-induced cardiomyopathy is multifactorial. Hence, targeting an individual pathway may not be effective in halting the extensive dysregulated immune response. Despite major advances in sepsis management strategies, no effective pharmacological strategies have been shown to treat or even reverse sepsis-induced cardiomyopathy. Melatonin, namely, N-acetyl-5-methoxytryptamine, is synthesized in the pineal gland of mammals and can also be produced in many cells and tissues. Melatonin has cardioprotective, neuroprotective, and anti-tumor activity. Several literature reviews have explored the role of melatonin in preventing sepsis-induced organ failure. Melatonin was found to act on different pathways that are involved in the pathogenesis of sepsis-induced cardiomyopathy. Through its antimicrobial, anti-inflammatory, and antioxidant activity, it offers a potential role in sepsis-induced cardiomyopathy. Its antioxidant activity is through free radical scavenging against reactive oxygen and nitrogen species and modulating the expression and activity of antioxidant enzymes. Melatonin anti-inflammatory activities control the overactive immune system and mitigate cytokine storm. Also, it mitigates mitochondrial dysfunction, a major mechanism involved in sepsis-induced cardiomyopathy, and thus controls apoptosis. Therefore, this review discusses melatonin as a promising drug for the management of sepsis-induced cardiomyopathy.

Mortality in patients with septic cardiomyopathy identified by longitudinal strain by speckle tracking echocardiography: An updated systematic review and meta-analysis with trial sequential analysis. Anaesth Crit Care Pain Med 2024; 43:101339. [PMID: 38128732 DOI: 10.1016/j.accpm.2023.101339] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2023] [Revised: 11/27/2023] [Accepted: 12/04/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Septic cardiomyopathy is associated with poor outcomes but its definition remains unclear. In a previous meta-analysis, left ventricular (LV) longitudinal strain (LS) showed significant prognostic value in septic patients, but findings were not robust due to a limited number of studies, differences in effect size and no adjustment for confounders. METHODS We conducted an updated systematic review (PubMed and Scopus up to 14.02.2023) and meta-analysis to investigate the association between LS and survival in septic patients. We included studies reporting global (from three apical views) or regional LS (one or two apical windows). A secondary analysis evaluated the association between LV ejection fraction (EF) and survival using data from the selected studies. RESULTS We included fourteen studies (1678 patients, survival 69.6%) and demonstrated an association between better performance (more negative LS) and survival with a mean difference (MD) of -1.45%[-2.10, -0.80] (p < 0.0001;I2 = 42%). No subgroup differences were found stratifying studies according to number of views used to calculate LS (p = 0.31;I2 = 16%), severity of sepsis (p = 0.42;I2 = 0%), and sepsis criteria (p = 0.59;I2 = 0%). Trial sequential analysis and sensitivity analyses confirmed the primary findings. Grade of evidence was low. In the included studies, thirteen reported LVEF and we found an association between higher LVEF and survival (MD = 2.44% [0.44,4.45]; p = 0.02;I2 = 42%). CONCLUSIONS We confirmed that more negative LS values are associated with higher survival in septic patients. The clinical relevance of this difference and whether the use of LS may improve understanding of septic cardiomyopathy and prognostication deserve further investigation. The association found between LVEF and survival is of unlikely clinical meaning. REGISTRATION PROSPERO number CRD42023432354.

Prevalence and prognosis of hyperdynamic left ventricular systolic function in septic patients: a systematic review and meta-analysis. Ann Intensive Care 2024; 14:22.

Abstract
PURPOSE The prevalence of hyperdynamic left ventricular (LV) systolic function in septic patients and its impact on mortality remain controversial. In this systematic review and meta-analysis, we investigated the prevalence and association of hyperdynamic LV systolic function with mortality in patients with sepsis. METHODS We searched MEDLINE, Cochrane Central Register of Controlled Trials, and Embase. Primary outcomes were the prevalence of hyperdynamic LV systolic function in adult septic patients and the associated short-term mortality as compared to normal LV systolic function. Hyperdynamic LV systolic function was defined using LV ejection fraction (LVEF) of 70% as cutoff. Secondary outcomes were heart rate, LV end-diastolic diameter (LVEDD), and E/e' ratio. RESULTS Four studies were included, and the pooled prevalence of hyperdynamic LV systolic function was 18.2% ([95% confidence interval (CI) 12.5, 25.8]; I2 = 7.0%, P < 0.0001). Hyperdynamic LV systolic function was associated with higher mortality: odds ratio of 2.37 [95%CI 1.47, 3.80]; I2 = 79%, P < 0.01. No difference was found in E/e' (P = 0.43) between normal and hyperdynamic LV systolic function, while higher values of heart rate (mean difference: 6.14 beats/min [95%CI 3.59, 8.69]; I2 = 51%, P < 0.0001) and LVEDD (mean difference: - 0.21 cm [95%CI - 0.33, - 0.09]; I2 = 73%, P < 0.001) were detected in patients with hyperdynamic LV systolic function. CONCLUSION The prevalence of hyperdynamic LV systolic function is not negligible in septic patients. Such a finding is associated with significantly higher short-term mortality as compared to normal LV systolic function.

Abstract
Myocardial dysfunction is common in patients admitted to the intensive care unit (ICU). Septic disease frequently results in cardiac dysfunction, and sepsis represents the most common cause of admission and death in the ICU. The association between left ventricular (LV) systolic dysfunction and mortality is not clear for critically ill patients. Conversely, LV diastolic dysfunction (DD) seems increasingly recognized as a factor associated with poor outcomes, not only in sepsis but also more generally in critically ill patients. Despite recent attempts to simplify the diagnosis and grading of DD, this remains relatively complex, with the need to use several echocardiographic parameters. Furthermore, the current guidelines have several intrinsic limitations when applied to the ICU setting. In this manuscript, we discuss the challenges in DD classification when applied to critically ill patients, the importance of left atrial pressure estimates for the management of patients in ICU, and whether the study of cardiac dysfunction spectrum during critical illness may benefit from the integration of left ventricular and left atrial strain data to improve diagnostic accuracy and implications for the treatment and prognosis.

Abstract
Patients with septic shock complicated by septic cardiomyopathy (SCM) can be extremely ill and at high risk for mortality. If early assessment of cardiac function is neglected during treatment, sepsis may be further exacerbated. We report a 77-year-old male patient with severe septic shock who underwent intraoperative transesophageal echocardiography (TEE) because of progressive circulatory instability, SCM was diagnosed. Further perioperative treatment to support the circulation was successfully adjusted based on TEE and pulse index continuous cardiac output (CO) by ProAQT/PulsioFlex hemodynamic monitoring. We should consider a diagnosis of SCM in the perioperative period and perform ultrasonography routinely. The use of TEE with ProAQT/PulsioFlex offers a new option for anesthetic management.

Abstract
BACKGROUND Sepsis is a leading cause of death and it is characterized not only by profound vasoplegia but also by myocardial dysfunction. Critical care echocardiography is the preferred modality for the initial assessment of the cause of shock. Moreover, it can be extremely helpful in the identification of progressing myocardial dysfunction during the course of sepsis, also known as septic cardiomyopathy. MAIN BODY One of the issues in the identification of septic cardiomyopathy is that it can be manifest with different clinical phenotypes, from overt biventricular dysfunction to isolated left ventricular (LV) systolic and/or diastolic dysfunction, from right ventricular (RV) systolic dysfunction to RV failure and dilatation. However, the commonly used echocardiography parameters for the assessment of LV and/or RV function are not always entirely reliable. Indeed, these are influenced by variable preload and afterload conditions imposed by critical illness such as fluid shifts, sedation level and mechanical ventilation with positive pressure. CONCLUSIONS Strain echocardiography is a promising tool for the early identification of myocardial dysfunction in the context of sepsis. Studies reporting data on strain echocardiography should be particularly detailed in order to increase the reproducibility of results and to favor comparison with future studies.

Abstract
Acute heart failure (AHF) is a sudden, life-threatening condition, defined as a gradual or rapid onset of symptoms and/or signs of HF. AHF requires urgent medical attention, being the most frequent cause of unplanned hospital admission in patients above 65 years of age. AHF is associated with a 4–12% in-hospital mortality rate and a 21–35% 1-year mortality rate post-discharge. Considering the serious prognosis in AHF patients, it is very important to understand the mechanisms and haemodynamic status in an individual AHF patient, thus preventing end-organ failure and death. Haemodynamic monitoring is a serial assessment of cardiovascular function, intended to detect physiologic abnormalities at the earliest stages, determine which interventions could be most effective, and provide the basis for initiating the most appropriate therapy and evaluate its effects. Over the past decades, haemodynamic monitoring techniques have evolved greatly. Nowadays, they range from very invasive to non-invasive, from intermittent to continuous, and in terms of the provided parameters. Invasive techniques contain pulmonary artery catheterization and transpulmonary thermodilution. Minimally invasive techniques include oesophageal Doppler and noncalibrated pulse wave analysis. Non-invasive techniques contain echocardiography, bioimpedance, and bioreactance techniques as well as non-invasive pulse contour methods. Each of these techniques has specific indications and limitations. In this article, we aimed to provide a pathophysiological explanation of the physical terms and parameters used for haemodynamic monitoring in AHF and to summarize the working principles, advantages, and disadvantages of the currently used methods of haemodynamic monitoring.

Abstract
Mitochondria, the intracellular organelles for cellular aerobic respiration and energy production, play an important role in the regulation of cell metabolism and cell fate. Mitophagy, a selective form of autophagy, maintains dynamic homeostasis of cells through targeting long-lived or defective mitochondria for timely clearance and recycling. Dysfunction in mitophagy is involved in the molecular mechanism responsible for the onset and development of human diseases. FUN14 domain containing 1 (FUNDC1) is a mitochondrial receptor located in the outer mitochondria membrane (OMM) to govern mitophagy process. Emerging evidence has demonstrated that levels and phosphorylation states of FUNDC1 are closely related to the occurrence, progression and prognosis of cardiovascular diseases, indicating a novel role for this mitophagy receptor in the regulation of mitochondrial homeostasis in cardiovascular system. Here we review mitophagy mediated by FUNDC1 in mitochondria and its role in various forms of cardiovascular diseases.

Abstract
CONTEXT Berberine (Ber) can increase the survival rate of septic mice and inhibit inflammation, but whether it has a protective effect on septic cardiomyopathy (SCM) is unclear. OBJECTIVE To investigate whether Ber ameliorates SCM in a rat model and its potential mechanism. MATERIALS AND METHODS Male SD rats were randomly divided into three groups: control (Con, n = 6) (DD H2O, 2 mL/100 g, ig, qd × 3 d, then saline, 10 mg/kg, ip); sepsis [LPS (lipopolysaccharide), n = 18] (LPS 10 mg/kg instead of saline, ip); and berberine intervention (Ber, n = 18) (Ber, 50 mg/kg instead of DD H2O, ig, qd × 3 d, LPS instead of saline, ip). Hemodynamics, HE staining, ELISA and western blot were performed at 6, 24, and 48 h after intraperitoneal injection of LPS to evaluate the effect of berberine in septic rats. RESULT Berberine could recover myocardial injury by partially increased ± dp/dt max (1151, 445 mmHg/s) and LVEDP levels (1.49 mmHg) with LPS-induced rats, as well as an ameliorated increase of cTnT (217.53 pg/mL) in the Ber group compared with that in the LPS group (at 24 h). In addition, HE staining results showed that berberine attenuated the myocardial cell swelling induced by LPS. In contrast to the LPS group, the up-regulation of TLR4, p65 TNF-α, and IL-1β were attenuated in the Ber group. DISCUSSION AND CONCLUSIONS Berberine showed a protective effect on septic cardiomyopathy rats possibly through inhibiting the activation of TLR4/NF-κB signalling pathway. Whether it improves SCM through other mechanisms is our ongoing research.

Abstract
BACKGROUND While recommended by international societal guidelines in the paediatric population, the use of venoarterial extracorporeal membrane oxygenation (VA ECMO) as mechanical circulatory support for refractory septic shock in adults is controversial. We aimed to characterise the outcomes of adults with septic shock requiring VA ECMO, and identify factors associated with survival. METHODS We searched Pubmed, Embase, Scopus and Cochrane databases from inception until 1st June 2021, and included all relevant publications reporting on > 5 adult patients requiring VA ECMO for septic shock. Study quality and certainty in evidence were assessed using the appropriate Joanna Briggs Institute checklist, and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, respectively. The primary outcome was survival to hospital discharge, and secondary outcomes included intensive care unit length of stay, duration of ECMO support, complications while on ECMO, and sources of sepsis. Random-effects meta-analysis (DerSimonian and Laird) were conducted. DATA SYNTHESIS We included 14 observational studies with 468 patients in the meta-analysis. Pooled survival was 36.4% (95% confidence interval [CI]: 23.6%-50.1%). Survival among patients with left ventricular ejection fraction (LVEF) < 20% (62.0%, 95%-CI: 51.6%-72.0%) was significantly higher than those with LVEF > 35% (32.1%, 95%-CI: 8.69%-60.7%, p = 0.05). Survival reported in studies from Asia (19.5%, 95%-CI: 13.0%-26.8%) was notably lower than those from Europe (61.0%, 95%-CI: 48.4%-73.0%) and North America (45.5%, 95%-CI: 16.7%-75.8%). GRADE assessment indicated high certainty of evidence for pooled survival. CONCLUSIONS When treated with VA ECMO, the majority of patients with septic shock and severe sepsis-induced myocardial depression survive. However, VA ECMO has poor outcomes in adults with septic shock without severe left ventricular depression. VA ECMO may be a viable treatment option in carefully selected adult patients with refractory septic shock.

Wang Y, Jasper H, Toan S, Muid D, Chang X, Zhou H. Mitophagy coordinates the mitochondrial unfolded protein response to attenuate inflammation-mediated myocardial injury. Redox Biol 2021; 45:102049. [PMID: 34174558 PMCID: PMC8246635 DOI: 10.1016/j.redox.2021.102049] [Citation(s) in RCA: 140] [Impact Index Per Article: 46.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 06/04/2021] [Accepted: 06/14/2021] [Indexed: 12/17/2022] Open
Abstract
Mitochondrial dysfunction is a fundamental challenge in septic cardiomyopathy. Mitophagy and the mitochondrial unfolded protein response (UPRmt) are the predominant stress-responsive and protective mechanisms involved in repairing damaged mitochondria. Although mitochondrial homeostasis requires the coordinated actions of mitophagy and UPRmt, their molecular basis and interactive actions are poorly understood in sepsis-induced myocardial injury. Our investigations showed that lipopolysaccharide (LPS)-induced sepsis contributed to cardiac dysfunction and mitochondrial damage. Although both mitophagy and UPRmt were slightly activated by LPS in cardiomyocytes, their endogenous activation failed to prevent sepsis-mediated myocardial injury. However, administration of urolithin A, an inducer of mitophagy, obviously reduced sepsis-mediated cardiac depression by normalizing mitochondrial function. Interestingly, this beneficial action was undetectable in cardiomyocyte-specific FUNDC1 knockout (FUNDC1CKO) mice. Notably, supplementation with a mitophagy inducer had no impact on UPRmt, whereas genetic ablation of FUNDC1 significantly upregulated the expression of genes related to UPRmt in LPS-treated hearts. In contrast, enhancement of endogenous UPRmt through oligomycin administration reduced sepsis-mediated mitochondrial injury and myocardial dysfunction; this cardioprotective effect was imperceptible in FUNDC1CKO mice. Lastly, once UPRmt was inhibited, mitophagy-mediated protection of mitochondria and cardiomyocytes was partly blunted. Taken together, it is plausible that endogenous UPRmt and mitophagy are slightly activated by myocardial stress and they work together to sustain mitochondrial performance and cardiac function. Endogenous UPRmt, a downstream signal of mitophagy, played a compensatory role in maintaining mitochondrial homeostasis in the case of mitophagy inhibition. Although UPRmt activation had no negative impact on mitophagy, UPRmt inhibition compromised the partial cardioprotective actions of mitophagy. This study shows how mitophagy modulates UPRmt to attenuate inflammation-related myocardial injury and suggests the potential application of mitophagy and UPRmt targeting in the treatment of myocardial stress. Mitochondrial dysfunction is a fundamental challenge in septic cardiomyopathy. LPS-induced sepsis contributes to cardiac dysfunction and mitochondrial damage. Endogenous UPRmt and mitophagy could be slightly activated by myocardial stress. Mitophagy modulates UPRmt to attenuate inflammation-related myocardial injury. Mitophagy and UPRmt targeting can be applied in treatment of myocardial stress.

Abstract
OBJECTIVE We conducted a systematic review and meta-analysis to investigate the prognostic value of echocardiographic parameters in pediatric septic patients. DATA SOURCES MEDLINE, PubMed, and EMBASE (last update April 5, 2020). STUDY SELECTION Observational studies of pediatric sepsis providing echocardiographic parameters in relation to mortality. DATA EXTRACTION Echocardiography data were categorized as those describing left ventricular systolic or diastolic function, right ventricular function, and strain echocardiography parameters. Data from neonates and children were considered separately. Analysis is reported as standardized mean difference and 95% CI. DATA SYNTHESIS We included data from 14 articles (n = 5 neonates, n = 9 children). The fractional shortening was the most commonly reported variable (11 studies, n = 555 patients) and we did not identify an association with mortality (standardized mean difference 0.22, 95% CI [-0.02 to 0.47]; p = 0.07, I2 = 28%). In addition, we did not find any association with mortality also for left ventricular ejection fraction (nine studies, n = 417; standardized mean difference 0.06, 95% CI [-0.27 to 0.40]; p = 0.72, I2 = 51%), peak velocity of systolic mitral annular motion determined by tissue Doppler imaging wave (four studies, n = 178; standardized mean difference -0.01, 95% CI [-0.34 to 0.33]; p = 0.97, I2 = 0%), and myocardial performance index (five studies, n = 219; standardized mean difference -0.51, 95% CI [-1.10 to 0.08]; p = 0.09, I2 = 63%). However, in regard to left ventricular diastolic function, there was an association with mortality for higher early wave of transmitral flow/peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging ratio (four studies, n = 189, standardized mean difference -0.45, 95% CI [-0.80 to -0.10]; p = 0.01, I2 = 0%) or lower peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging wave (three studies, n = 159; standardized mean difference 0.49, 95% CI [0.13-0.85]; p = 0.008, I2 = 0%). We did not find any association with mortality for early wave of transmitral flow/late (atrial) wave of trans-mitral flow ratio (six studies, n = 273; standardized mean difference 0.28, 95% CI [-0.42 to 0.99]; p = 0.43, I2 = 81%) and peak velocity of systolic mitral annular motion determined by tissue Doppler imaging wave measured at the tricuspid annulus (three studies, n = 148; standardized mean difference -0.18, 95% CI [-0.53 to 0.17]; p = 0.32, I2 = 0%). Only a few studies were conducted with strain echocardiography. CONCLUSIONS This meta-analysis of echocardiography parameters in pediatric sepsis failed to find any association between the measures of left ventricular systolic or right ventricular function and mortality. However, mortality was associated with higher early wave of transmitral flow/peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging or lower peak velocity of early diastolic mitral annular motion determined by tissue Doppler imaging, indicating possible importance of left ventricular diastolic dysfunction. These are preliminary findings because of high clinical heterogeneity in the studies to date.

Abstract
PURPOSE Septic induced cardiomyopathy has a wide spectrum of presentation, being associated with systolic and/or diastolic dysfunction. There is currently no evidence of association between left ventricular (LV) systolic dysfunction and mortality in septic patients. METHODS We conducted a systematic review and meta-analysis to investigate the association between systolic wave (s') obtained with Tissue Doppler Imaging (TDI) and mortality in septic patients. Secondary outcome was the association of LV ejection fraction with mortality. RESULTS In the primary analysis we included a total of 13 studies (1197 patients, mortality 39.9%); overall s' wave was not significantly different between survivors and non-survivors (Standardized Mean Difference 0.20, 95%Confidence-Interval - 0.18, 0.59). This result was confirmed also in sub-groups analyses according to regional criteria of TDI sampling. A post-hoc analysis including only septic shock patients confirmed that s' wave was not associated with mortality. Several sensitivity analyses confirmed these results. We found no evidence of publication bias. The secondary analysis (11 studies, 1081 patients, mortality 36.7%) showed that LV ejection fraction was not associated with mortality (Mean Difference 0.98, 95% Confidence-Interval - 1.79,3.75). CONCLUSIONS There is no association between mortality and LV systolic function as evaluated by TDI s' wave in septic patients.

Prognostic Role of Left Ventricular Systolic Function Measured by Speckle Tracking Echocardiography in Septic Shock. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7927353.

Abstract
Background Left ventricular (LV) systolic dysfunction is common in septic shock. Global longitudinal strain (GLS) measured by speckle tracking echocardiography (STE) is a useful marker of intrinsic left ventricular systolic function. However, the association between left ventricular GLS and outcome in septic patients is not well understood. We performed this prospective study to investigate the prognostic value of LV systolic function utilizing speckle tracking echocardiography in patients with septic shock. Methods All the patients with septic shock based on sepsis-3 definition admitted to the intensive care unit were prospectively studied with STE within 24 hours after the onset of septic shock. Baseline clinical and echocardiographic variables were collected. The primary outcome was in-hospital mortality. Results During a 19-month period, 90 consecutive patients were enrolled in the study. The in-hospital mortality rate was 43.3%. Compared with survivors, nonsurvivors exhibited significantly less negative GLS (−13.1 ± 3.3% versus −15.8 ± 2.9%; p < 0.001), which reflected worse LV systolic function. The area under the ROC curves of GLS for the prediction of mortality was 0.76 (95% CI 0.67 to 0.87). Patients with GLS > −14.1% showed a significantly higher mortality rate (67.7% versus 15.6%; p < 0.0001; log‐rank = 23.3; p < 0.0001). In the multivariate analysis, GLS (HR, 1.27; 95% CI 1.07 to 1.50, p = 0.005) and SOFA scores (HR, 1.27; 95% CI 1.08 to 1.50, p = 0.004) were independent predictors of in-hospital mortality. Conclusions Our study indicated that LV systolic function measured by STE might be associated with mortality in patients with septic shock.

Abstract
Myocardial injury is a serious complication of sepsis. The present study aimed to identify potential biomarkers of sepsis-induced myocardial injury. Differentially expressed genes (DEGs) in patients and mice with sepsis-induced myocardial injury were identified via bioinformatic analysis. The identified DEG was tested in elderly patients with sepsis-induced myocardial injury. We identified 19 co-expressed DEGs. The most significant DEG was eotaxin-1/CCL11. We enrolled 25 controls without infections and 28 patients with sepsis-induced myocardial injury. Six of patients died within 30 days. Circulating eotaxin-1/CCL11 levels were significantly higher in patients with sepsis-induced myocardial injury than controls and were higher in non-survivors than survivors (both P < 0.01). Eotaxin-1/CCL11 was positively correlated with troponin I (r=0.48, P=0.01), B-type natriuretic peptide (BNP, r=0.44, P=0.02), and white blood cell (WBC) count (r=0.41, P=0.03). For the prediction of 30-day mortality, eotaxin-1/CCL11 had the greatest discriminatory ability (AUC 0.97) compared with troponin I (AUC 0.89), BNP (AUC 0.80), and WBC count (AUC 0.86). Taken together, eotaxin-1/CCL11 was upregulated in sepsis-injured myocardium and circulating eotaxin-1/CCL11 was a biomarker for predicting severity and mortality of elderly patients with sepsis-induced myocardial injury. These results suggest that eotaxin-1/CCL11 may become a useful biomarkers and potential therapeutic target for sepsis-induced myocardial injury.
