    Abstract Mitochondria are key to the cellular response to energetic demand, but are also vital to reactive oxygen species signaling, calcium hemostasis, and regulation of cell death. Cardiac surgical patients with diabetes, heart failure, advanced age, or cardiomyopathies may have underlying mitochondrial dysfunction or be more sensitive to perioperative mitochondrial injury. Mitochondrial dysfunction, due to ischemia/reperfusion injury and an increased systemic inflammatory response due to exposure to cardiopulmonary bypass and surgical tissue trauma, impacts myocardial contractility and predisposes to arrhythmias. Strategies for perioperative mitochondrial protection and recovery include both well-established cardioprotective protocols and targeted therapies that remain under investigation.

    Title translation Accumulation and transport of ammonium in aquitards in the Pearl River Delta (China) in the last 10,000� years: conceptual and numerical models
    Abstract Generation, accumulation and migration of ammonium in the coastal aquifer-aquitard system of the Pearl River Delta, China, are a result of complex and long-term processes including sea-level changes, shoreline migration, sedimentation, decomposition of organic matter, solute-transport processes, and chemical reaction during the Holocene. Simulation of long-term ammonium distribution is not well addressed in the literature due to the difficulties in quantifying the complex geochemical processes. Salinity and ammonium profiles in the aquitards at two typical sites were obtained from geochemical analyses of soil and water samples. One-dimensional numerical models were used to integrate present knowledge of stratigraphy, historical evolution of the geological system during the Holocene, and the processes related to the generation and migration of ammonium. The ammonium generation and accumulation were approximated by an exponential function, and a moving boundary condition was used to reflect the sea-level changes during the Holocene. The observed salinity profiles were used to estimate flow and dispersion parameters, then the observed ammonium profiles were used to estimate the reactive parameters related to ammonium generation. The reasonably good match between the simulated and observed results demonstrates that the models can capture the dominant processes that control the generation and movement of ammonium.

    Abstract Acute kidney injury (AKI) is a common postoperative complication after cardiac surgery with cardiopulmonary bypass (CPB), and leads to significant morbidity, mortality, and cost. Although early recognition and management of AKI may reduce the burden of renal disease, reliance on serum creatinine accumulation to confidently diagnose it leads to a significant and important delay (up to 48 hours). Hence, a search for earlier AKI biomarkers is warranted. The renal-resistive index (RRI) is a promising early AKI biomarker that reflects intrarenal arterial pulsatility as reflected by the peak systolic and end-diastolic blood velocities divided by the peak systolic velocity. During cardiac surgery, post-CPB elevation of RRI is correlated with renal injury. The RRI is influenced by intrarenal and extrarenal factors, as well as different hemodynamic states. Understanding its limitations may increase its usefulness as an early AKI biomarker. For example, tachycardia or aortic stenosis typically results in a lower RRI, whereas bradycardia or increased systemic pulse pressure (as seen with aortic insufficiency) are associated with a higher RRI, unrelated to any intrarenal effects. In this E-Challenge, the authors present two cases in which the RRI was used to evaluate a patient's risk of developing AKI.

    Abstract Significance: Mitochondria play a vital role in cellular homeostasis and are susceptible to damage from inflammatory mediators released by the host defense. Cellular recovery depends, in part, on mitochondrial quality control programs, including mitochondrial biogenesis.
    Recent advances: Early-phase inflammatory mediator proteins interact with PRRs to activate NF-κB-, MAPK-, and PKB/Akt-dependent pathways, resulting in increased expression or activity of coactivators and transcription factors (e.g., PGC-1α, NRF-1, NRF-2, and Nfe2l2) that regulate mitochondrial biogenesis. Inflammatory upregulation of NOS2-induced NO causes mitochondrial dysfunction, but NO is also a signaling molecule upregulating mitochondrial biogenesis via PGC-1α, participating in Nfe2l2-mediated antioxidant gene expression and modulating inflammation. NO and reactive oxygen species generated by the host inflammatory response induce the redox-sensitive HO-1/CO system, causing simultaneous induction of mitochondrial biogenesis and antioxidant gene expression.
    Critical issues: Recent evidence suggests that mitochondrial biogenesis and mitophagy are coupled through redox pathways; for instance, parkin, which regulates mitophagy in chronic inflammation, may also modulate mitochondrial biogenesis and is upregulated through NF-κB. Further research on parkin in acute inflammation is ongoing. This highlights certain common features of the host response to acute and chronic inflammation, but caution is warranted in extrapolating findings across inflammatory conditions.
    Future directions: Inflammatory mitochondrial dysfunction and oxidative stress initiate further inflammatory responses through DAMP/PRR interactions and by inflammasome activation, stimulating mitophagy. A deeper understanding of mitochondrial quality control programs' impact on intracellular inflammatory signaling will improve our approach to the restoration of mitochondrial homeostasis in the resolution of acute inflammation.

    Abstract Background: Recent studies suggest measles-induced immune amnesia could have long-term immunosuppressive effects via preferential depletion of memory CD150+ lymphocytes, and associations with a 2-3 year period of increased mortality and morbidity from infectious diseases other than measles has been shown in children from wealthy and low-income countries. To further examine the associations previous measles virus infection may have on immunologic memory among children in the Democratic Republic of the Congo (DRC), we assessed tetanus antibody levels among fully vaccinated children, with and without a history of measles.
    Methods: We assessed 711 children 9-59 months of age whose mothers were selected for interview in the 2013-2014 DRC Demographic and Health Survey. History of measles was obtained by maternal report and classification of children who had measles in the past was completed using maternal recall and measles IgG serostatus obtained from a multiplex chemiluminescent automated immunoassay dried blood spot analysis. Tetanus IgG antibody serostatus was similarly obtained. A logistic regression model was used to identify association of measles and other predictors with subprotective tetanus IgG antibody.
    Results: Subprotective geometric mean concentration tetanus IgG antibody values were seen among fully vaccinated children 9-59 months of age, who had a history of measles. Controlling for potential confounding variables, children classified as measles cases were less likely to have seroprotective tetanus toxoid antibody (odds ratio: 0.21; 95% confidence interval: 0.08-0.55) compared with children who had not had measles.
    Conclusions: History of measles was associated with subprotective tetanus antibody among this sample of children in the DRC who were 9-59 months of age and fully vaccinated against tetanus.

    Abstract Background: Acute kidney injury (AKI) is a common and serious complication of cardiac surgical procedures for which unrecognized heterogeneity may underpin poor success in identifying effective therapies. We aimed to identify phenotypically similar groups of patients as defined by their postoperative creatinine trajectories.
    Methods: This was a retrospective, single-center cohort study in an academic tertiary care center including patients undergoing coronary artery bypass graft procedures. AKI phenotypes were evaluated through latent class mixed modeling of serum creatinine patterns (trajectories). To identify trajectory phenotypes, modeling was performed using postoperative creatinine values from 50% of patients (development cohort) and for comparison similarly conducted for the remaining sample (validation cohort). Subsequent assessments included comparisons of classes between development and validation cohorts for consistency and stability, and among classes for patient and procedural characteristics, complications, and long-term survival.
    Results: We identified 12 AKI trajectories in both the development (n = 2647) and validation cohorts (n = 2647). Discrimination among classes was good (mean posterior class membership probability, 66%-88%), with differences in rate, timing, and degree of serum creatinine rise/fall, and recovery. In matched class comparisons between cohorts, many other phenotypic similarities were present. Notably, 4 high-risk phenotypes had greater long-term risk for death relative to lower risk classes.
    Conclusions: Latent class mixed modeling identified 12 reproducible AKI classes (serum creatinine trajectory phenotypes), including 4 with higher risk of poor outcome, in patients following coronary artery bypass graft procedures. Such hidden structure offers a novel approach to grouping patients for renoprotection investigations in addition to reanalysis of previously conducted trials.

    Abstract Objectives: The prediction of right heart failure (RHF) after left ventricular assist device (LVAD) implantation remains a challenge. Recently, risk scores were derived from analysis of the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) data, the EUROMACS-RHF, and the modified postoperative EUROMACS-RHF. The authors assessed the performance characteristics of these 2 risk score formulations in a continuous-flow LVAD cohort at their institution.
    Design: A retrospective, observational study.
    Setting: At a tertiary-care academic medical center.
    Participants: Adult patients who underwent durable LVAD implantation between 2015 and 2018.
    Interventions: None MEASUREMENTS AND MAIN RESULTS: Early post-LVAD RHF was defined as follows: (1) need for right ventricular assist device, or (2) inotropic or inhaled pulmonary vasodilator support for ≥14 postoperative days. The authors used logistic regression and examined receiver operating characteristic (ROC) curves to evaluate the ability of the 2 risk scores to distinguish between outcome groups. A total of 207 patients met the inclusion criteria. Of the patients, 16% developed RHF (33/207). The EUROMACS-RHF score was not predictive of RHF in the authors' cohort (odds ratio [OR] 1.25; 95% CI [0.99-1.60]; p = 0.06), but the postoperative EUROMACS-RHF CPB score was significantly associated (OR 1.38; 95% CI [1.03-1.89]; p = 0.03). The scores had similar ROC curves, with weak discriminatory performance: 0.601 (95% CI [0.509-0.692]) and 0.599 (95% CI [0.505-0.693]) for EUROMACS-RHF and postoperative EUROMACS-RHF, respectively.
    Conclusions: In the authors' single-center retrospective analysis, the EUROMACS-RHF risk score did not predict early RHF. An optimized risk score for the prediction of RHF after LVAD implantation remains an urgent unmet need.
