JAMIA Open 2024; 7:ooae048. [PMID: 38978714 PMCID: PMC11229986 DOI: 10.1093/jamiaopen/ooae048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 02/21/2024] [Accepted: 05/29/2024] [Indexed: 07/10/2024] Open
Abstract
Introduction The Pediatric Surviving Sepsis Campaign supports the implementation of automated tools for early sepsis recognition. In 2019 the C.S. Mott Children's Hospital Pediatric Intensive Care Unit deployed an electronic medical record (EMR)-based screening for early recognition and treatment of sepsis. Materials and Methods We analyzed all automated primary sepsis alerts, secondary screens, and bedside huddles from November 2019 to January 2020 (Cohort 1) and from November 2020 to January 2021 (Cohort 2) to identify barriers and facilitators for the use of this tool. We distributed surveys to frontline providers to gather feedback on end-user experience. Results In Cohort 1, 895 primary alerts were triggered, yielding 503 completed secondary screens and 40 bedside huddles. In Cohort 2, 925 primary alerts were triggered, yielding 532 completed secondary screens and 12 bedside huddles. Surveys assessing end-user experience identified the following facilitators: (1) 73% of nurses endorsed the bedside huddle as value added; (2) 74% of medical providers agreed the bedside huddle increased the likelihood of interventions. The greatest barriers to successful implementation included the (1) overall large number of primary alerts from the automated tool and (2) rate of false alerts, many due to routine respiratory therapy interventions. Discussion Our data suggests that the successful implementation of EMR-based sepsis screening tools requires countermeasures focusing on 3 key drivers for change: education, technology, and patient safety. Conclusion While both medical providers and bedside nurses found merit in our EMR-based sepsis early recognition system, continued refinement is necessary to avoid sepsis alert fatigue.

Abstract
Acute neurologic injury is common in critically ill children. Some conditions - such as traumatic brain injury, meningitis, and hypoxic-ischemic injury following cardiac arrest - require careful consideration of cerebral physiology. Specialized neuromonitoring techniques provide insight regarding patient-specific and disease-specific insight that can improve diagnostic accuracy, aid in targeting therapeutic interventions, and provide prognostic information. In this review, we will discuss recent innovations in invasive (e.g., intracranial pressure monitoring and related computed indices) and noninvasive (e.g., transcranial doppler, near-infrared spectroscopy) neuromonitoring techniques used in traumatic brain injury, central nervous system infections, and after cardiac arrest. We will discuss the pertinent physiological mechanisms interrogated by each technique and discuss available evidence for potential clinical application. We will also discuss the use of innovative neuromonitoring techniques to detect and manage neurologic complications in critically ill children with systemic illness, focusing on sepsis and cardiorespiratory failure requiring extracorporeal membrane oxygenation.

Abstract
OBJECTIVES In critically ill children with severe sepsis, septic cardiomyopathy (SCM) denotes the subset of patients who have myocardial dysfunction with poor response to fluid and inotropic support, and higher mortality risk. The objective of this review was to evaluate the role of speckle-tracking echocardiography (STE) in the diagnosis and prognosis of pediatric SCM in the PICU setting. DATA SOURCES We performed detailed searches using PubMed, Scopus, Web of Science, and Google Scholar. Reference lists of all included studies were also examined for further identification of potentially relevant studies. STUDY SELECTION Studies with the following medical subject headings and keywords were selected: speckle-tracking echocardiography, strain imaging, global longitudinal strain, echocardiography, sepsis, severe sepsis, septic shock, septic cardiomyopathy, and myocardial dysfunction. DATA EXTRACTION The following data were extracted from all included studies: demographics, diagnoses, echocardiographic parameters, severity of illness, PICU management, and outcomes. DATA SYNTHESIS STE is a relatively new echocardiographic technique that directly quantifies myocardial contractility. It has high sensitivity in diagnosing SCM, correlates well with illness severity, and has good prognosticating value as compared with conventional echocardiographic parameters. Further studies are required to establish its role in evaluating biventricular systolic and diastolic dysfunction, and to investigate whether it has a role in individualizing treatment and improving treatment outcomes in this group of patients. CONCLUSIONS STE is a useful adjunct to conventional measures of cardiac function on 2D-echocardiography in the assessment of pediatric SCM in the PICU.

[PMID: 38895139 PMCID: PMC11182881 DOI: 10.2147/jir.s460413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Accepted: 05/22/2024] [Indexed: 06/21/2024] Open
Abstract
Background Globally, the subsequent complications that accompany sepsis result in remarkable morbidity and mortality rates. The lung is among the vulnerable organs that incur the sepsis-linked inflammatory storm and frequently culminates into ARDS/ALI. The metformin-prescribed anti-diabetic drug has been revealed with anti-inflammatory effects in sepsis, but the underlying mechanisms remain unclear. This study aimed to ascertain metformin's effects and functions in a young mouse model of sepsis-induced ALI. Methods Mice were randomly divided into 4 groups: sham, sham+ Met, CLP, and CLP+ Met. CLP was established as the sepsis-induced ALI model accompanied by intraperitoneal metformin treatment. At day 7, the survival state of mice was noted, including survival rate, weight, and M-CASS. Lung histological pathology and injury scores were determined by hematoxylin-eosin staining. The pulmonary coefficient was used to evaluate pulmonary edema. Furthermore, IL-1β, CCL3, CXCL11, S100A8, S100A9 and NLRP3 expression in tissues collected from lungs were determined by qPCR, IL-1β, IL-18, TNF-α by ELISA, caspase-1, ASC, NLRP3, P65, p-P65, GSDMD-F, GSDMD-N, IL-1β and S100A8/A9 by Western blot. Results The data affirmed that metformin enhanced the survival rate, lessened lung tissue injury, and diminished the expression of inflammatory factors in young mice with sepsis induced by CLP. In contrast to sham mice, the CLP mice were affirmed to manifest ALI-linked pathologies following CLP-induced sepsis. The expressions of pro-inflammatory factors, for instance, IL-1β, IL-18, TNF-α, CXCL11, S100A8, and S100A9 are markedly enhanced by CLP, while metformin abolished this adverse effect. Western blot analyses indicated that metformin inhibited the sepsis-induced activation of GSDMD and the upregulation of S100A8/A9, NLRP3, and ASC. Conclusion Metformin could improve the survival rate, lessen lung tissue injury, and minimize the expression of inflammatory factors in young mice with sepsis induced by CLP. Metformin reduced sepsis-induced ALI via inhibiting the NF-κB signaling pathway and inhibiting pyroptosis by the S100A8/A9-NLRP3-IL-1β pathway.

Abstract
Sepsis is the leading cause of death of hospitalized children worldwide. Despite the established link between immune dysregulation and mortality in pediatric sepsis, it remains unclear which host immune factors contribute causally to adverse sepsis outcomes. Identifying modifiable pathobiology is an essential first step to successful translation of biologic insights into precision therapeutics. We designed a prospective, longitudinal cohort study of 88 critically ill pediatric patients with multiple organ dysfunction syndrome (MODS), including patients with and without sepsis, to define subphenotypes associated with targetable mechanisms of immune dysregulation. We first assessed plasma proteomic profiles and identified shared features of immune dysregulation in MODS patients with and without sepsis. We then employed consensus clustering to define three subphenotypes based on protein expression at disease onset and identified a strong association between subphenotype and clinical outcome. We next identified differences in immune cell frequency and activation state by MODS subphenotype and determined the association between hyperinflammatory pathway activation and cellular immunophenotype. Using single cell transcriptomics, we demonstrated STAT3 hyperactivation in lymphocytes from the sickest MODS subgroup and then identified an association between STAT3 hyperactivation and T cell immunometabolic dysregulation. Finally, we compared proteomics findings between patients with MODS and patients with inborn errors of immunity that amplify cytokine signaling pathways to further assess the impact of STAT3 hyperactivation in the most severe patients with MODS. Overall, these results identify a potentially pathologic and targetable role for STAT3 hyperactivation in a subset of pediatric patients with MODS who have high severity of illness and poor prognosis.

Abstract
Importance Pediatric consensus guidelines recommend antibiotic administration within 1 hour for septic shock and within 3 hours for sepsis without shock. Limited studies exist identifying a specific time past which delays in antibiotic administration are associated with worse outcomes. Objective To determine a time point for antibiotic administration that is associated with increased risk of mortality among pediatric patients with sepsis. Design, Setting, and Participants This retrospective cohort study used data from 51 US children's hospitals in the Improving Pediatric Sepsis Outcomes collaborative. Participants included patients aged 29 days to less than 18 years with sepsis recognized within 1 hour of emergency department arrival, from January 1, 2017, through December 31, 2021. Piecewise regression was used to identify the inflection point for sepsis-attributable 3-day mortality, and logistic regression was used to evaluate odds of sepsis-attributable mortality after adjustment for potential confounders. Data analysis was performed from March 2022 to February 2024. Exposure The number of minutes from emergency department arrival to antibiotic administration. Main Outcomes and Measures The primary outcome was sepsis-attributable 3-day mortality. Sepsis-attributable 30-day mortality was a secondary outcome. Results A total of 19 515 cases (median [IQR] age, 6 [2-12] years) were included. The median (IQR) time to antibiotic administration was 69 (47-116) minutes. The estimated time to antibiotic administration at which 3-day sepsis-attributable mortality increased was 330 minutes. Patients who received an antibiotic in less than 330 minutes (19 164 patients) had sepsis-attributable 3-day mortality of 0.5% (93 patients) and 30-day mortality of 0.9% (163 patients). Patients who received antibiotics at 330 minutes or later (351 patients) had 3-day sepsis-attributable mortality of 1.2% (4 patients), 30-day mortality of 2.0% (7 patients), and increased adjusted odds of mortality at both 3 days (odds ratio, 3.44; 95% CI, 1.20-9.93; P = .02) and 30 days (odds ratio, 3.63; 95% CI, 1.59-8.30; P = .002) compared with those who received antibiotics within 330 minutes. Conclusions and Relevance In this cohort of pediatric patients with sepsis, 3-day and 30-day sepsis-attributable mortality increased with delays in antibiotic administration 330 minutes or longer from emergency department arrival. These findings are consistent with the literature demonstrating increased pediatric sepsis mortality associated with antibiotic administration delay. To guide the balance of appropriate resource allocation with time for adequate diagnostic evaluation, further research is needed into whether there are subpopulations, such as those with shock or bacteremia, that may benefit from earlier antibiotics.

Abstract
OBJECTIVES To develop a desirability of outcome ranking (DOOR) scale for use in children with septic shock and determine its correlation with a decrease in 3-month postadmission health-related quality of life (HRQL) or death. DESIGN Secondary analysis of the Life After Pediatric Sepsis Evaluation prospective study. SETTING Twelve U.S. PICUs, 2013-2017. PATIENTS Children (1 mo-18 yr) with septic shock. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We applied a 7-point pediatric critical care (PCC) DOOR scale: 7: death; 6: extracorporeal life support; 5: supported by life-sustaining therapies (continuous renal replacement therapy, vasoactive, or invasive ventilation); 4: hospitalized with or 3: without organ dysfunction; 2: discharged with or 1: without new morbidity to patients by assigning the highest applicable score on specific days post-PICU admission. We analyzed Spearman rank-order correlations (95% CIs) between proximal outcomes (PCC-DOOR scale on days 7, 14, and 21, ventilator-free days, cumulative 28-day Pediatric Logistic Organ Dysfunction-2 (PELOD-2) scores, and PICU-free days) and 3-month decrease in HRQL or death. HRQL was measured by Pediatric Quality of Life Inventory 4.0 or Functional Status II-R for patients with developmental delay. Patients who died were assigned the worst possible HRQL score. PCC-DOOR scores were applied to 385 patients, median age 6 years (interquartile range 2, 13) and 177 (46%) with a complex chronic condition(s). Three-month outcomes were available for 245 patients (64%) and 42 patients (17%) died. PCC-DOOR scale on days 7, 14, and 21 demonstrated fair correlation with the primary outcome (-0.42 [-0.52, -0.31], -0.47 [-0.56, -0.36], and -0.52 [-0.61, -0.42]), similar to the correlations for cumulative 28-day PELOD-2 scores (-0.51 [-0.59, -0.41]), ventilator-free days (0.43 [0.32, 0.53]), and PICU-free days (0.46 [0.35, 0.55]). CONCLUSIONS The PCC-DOOR scale is a feasible, practical outcome for pediatric sepsis trials and demonstrates fair correlation with decrease in HRQL or death at 3 months.

Abstract
BACKGROUND There is limited understanding of alteration of gut microbiota and metabolome in children with sepsis/septic shock. METHODS In this prospective observational study carried out in a pediatric intensive care unit of a tertiary care center from 2020 to 2022, patients aged <17 years with sepsis/septic shock and healthy children (HC) were enrolled. We characterized the gut bacterial compositions by metagenome sequencing and metabolomes by untargeted gas chromatography-mass spectrometry. The primary outcome was to compare the gut microbiota and metabolome of children with sepsis/septic shock with that of HC. The Firmicutes/Bacteroidetes (F/B) ratio was compared between children with sepsis/septic shock and HC. Key secondary outcomes were to evaluate association of factors associated with a low F/B ratio in children with sepsis/septic shock. RESULTS A total of 40 children (63% boys) (15 children with sepsis and septic shock and 10 healthy children) with a median (IQR) age of 5.5 (1.5, 10) years were enrolled. In the fecal microbiota, the α-diversity index including Shannon and Simpson indices of the sepsis/septic shock groups was significantly lower than that of the HC. The samples lacked beneficial Bifidobacterium spp. and were dominated by Bacteroides, Enterobacteriaceae, and Enterococcaceae. There was reduction in short-chain fatty acids (SCFAs) in patients with sepsis/septic shock as compared to healthy children. A lower F/B ratio (≤1.57) of the gut microbiota discriminated well between children with sepsis/septic shock and HC. Factors associated with lower F/B ratio were male gender, clinical GI dysfunction, elevated inflammatory markers, and higher organ failure scores. CONCLUSION There were significant alterations in the gut microbiota and metabolome in children with sepsis/septic shock as compared to healthy children. Larger study is needed to confirm these exploratory findings and develop potential therapeutic targets that will improve outcomes in children with sepsis/septic shock.

Abstract
Ascorbic acid, or vitamin C, is a physiological antioxidant that has been found to be deficient in critically ill adults with sepsis and acute respiratory distress system. In adults, ascorbic acid supplementation has been shown to reduce the need for vasopressors and mechanical ventilation. This study aimed to describe the prevalence of ascorbic acid deficiency in critically ill pediatric patients. This prospective, single-centered study analyzed 34 patients aged 1 month to 18 years old with septic shock and/or acute respiratory failure requiring mechanical ventilation in a quaternary, urban, pediatric intensive care unit. Plasma ascorbic acid levels were measured by high-performance liquid chromatography within 24 hours of meeting eligibility criteria. The median level was 23.34 µM (IQR [11.45, 39.14]). Twenty-three patients had repeat samples that were collected 3 to 5 days later. The median for repeat samples was higher at 42.41 µM (IQR [13.08, 62.43]). Patients who were enterally fed had significantly higher levels than those who were not (62.4 ± 7.7 µM vs. 32.4 ± 7.1 µM; p = 0.03). Ascorbic acid levels vary widely among critically ill children with septic shock and/or respiratory failure requiring mechanical ventilation, but one-half of our patients had deficient levels that are typically seen in scurvy. Further studies are warranted to investigate the significance of low levels as well as the impact of normalizing levels through nutritional support.

Abstract
OBJECTIVES Identification of children with sepsis-associated multiple organ dysfunction syndrome (MODS) at risk for poor outcomes remains a challenge. We sought to the determine reproducibility of the data-driven "persistent hypoxemia, encephalopathy, and shock" (PHES) phenotype and determine its association with inflammatory and endothelial biomarkers, as well as biomarker-based pediatric risk strata. DESIGN We retrained and validated a random forest classifier using organ dysfunction subscores in the 2012-2018 electronic health record (EHR) dataset used to derive the PHES phenotype. We used this classifier to assign phenotype membership in a test set consisting of prospectively (2003-2023) enrolled pediatric septic shock patients. We compared profiles of the PERSEVERE family of biomarkers among those with and without the PHES phenotype and determined the association with established biomarker-based mortality and MODS risk strata. SETTING Twenty-five PICUs across the United States. PATIENTS EHR data from 15,246 critically ill patients with sepsis-associated MODS split into derivation and validation sets and 1,270 pediatric septic shock patients in the test set of whom 615 had complete biomarker data. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The area under the receiver operator characteristic curve of the modified classifier to predict PHES phenotype membership was 0.91 (95% CI, 0.90-0.92) in the EHR validation set. In the test set, PHES phenotype membership was associated with both increased adjusted odds of complicated course (adjusted odds ratio [aOR] 4.1; 95% CI, 3.2-5.4) and 28-day mortality (aOR of 4.8; 95% CI, 3.11-7.25) after controlling for age, severity of illness, and immunocompromised status. Patients belonging to the PHES phenotype were characterized by greater degree of systemic inflammation and endothelial activation, and were more likely to be stratified as high risk based on PERSEVERE biomarkers predictive of death and persistent MODS. CONCLUSIONS The PHES trajectory-based phenotype is reproducible, independently associated with poor clinical outcomes, and overlapped with higher risk strata based on prospectively validated biomarker approaches.

Abstract
Critical illness syndromes including sepsis, acute respiratory distress syndrome, and acute kidney injury (AKI) are associated with high in-hospital mortality and long-term adverse health outcomes among survivors. Despite advancements in care, clinical and biological heterogeneity among patients continues to hamper identification of efficacious therapies. Precision medicine offers hope by identifying patient subclasses based on clinical, laboratory, biomarker and 'omic' data and potentially facilitating better alignment of interventions. Within the previous two decades, numerous studies have made strides in identifying gene-expression based endotypes and clinico-biomarker based phenotypes among critically ill patients associated with differential outcomes and responses to treatment. In this state-of-the-art review, we summarize the biological similarities and differences across the various subclassification schemes among critically ill patients. In addition, we highlight current translational gaps, the need for advanced scientific tools, human-relevant disease models, to gain a comprehensive understanding of the molecular mechanisms underlying critical illness subclasses.

Abstract
The resistance to antibiotics in Gram-negative bacilli causing sepsis is a warning sign of failure of therapy. Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli (E. coli) represent major Gram-negative bacilli associated with sepsis. Quinolone resistance is an emerging resistance among E. coli and K. pneumoniae. Therefore, the present study aimed to study the presence of plasmid-mediated quinolone resistance (PMQR) genes qnrA, qnrB, and qnrS by polymerase chain reaction (PCR) in E. coli and K. pneumoniae isolated from pediatric patients with sepsis. This was a retrospective cross-sectional study that included pediatric patients with healthcare-associated sepsis. The E. coli and K. pneumoniae isolates were identified by microbiological methods. PMQR genes namely qnrA, qnrB, and qnrS were detected in E. coli and K. pneumoniae isolates by PCR. The results were analyzed by SPPS24, and the qualitative data was analyzed as numbers and percentages and comparison was performed by Chi-square test, P was significant if < 0.05. The most prevalent gene detected by PCR was qnrA (75%), followed by qnrB (28.1%), and qnrS (25%). The most frequently detected qnr gene in E coli and K. pneumoniae was qnrA (28.8%, and 16.3% respectively). The present study highlights the high prevalence of ciprofloxacin resistance among E. coli and K. pneumoniae isolated from pediatric patients with healthcare-associated sepsis. There was a high frequency of PMQR genes in E. coli and K. pneumoniae isolated from pediatric patients. Therefore, it is important to monitor the spread of PMQR genes in clinical isolates to ensure efficient antibiotic use in those children. The finding denotes the importance of an antibiotics surveillance program.

Abstract
Invasive bacterial infections and sepsis are persistent global health concerns, complicated further by the escalating threat of antibiotic resistance. Over the past 40 years, collaborative endeavors to improve the diagnosis and critical care of septic patients have improved outcomes, yet grappling with the intricate immune dysfunction underlying the septic condition remains a formidable challenge. Anti-inflammatory interventions that exhibited promise in murine models failed to manifest consistent survival benefits in clinical studies through recent decades. Novel therapeutic approaches that target bacterial virulence factors, for example with monoclonal antibodies, aim to thwart pathogen-driven damage and restore an advantage to the immune system. A pioneering technology addressing this challenge is biomimetic nanoparticles-a therapeutic platform featuring nanoscale particles enveloped in natural cell membranes. Borne from the quest for a durable drug delivery system, the original red blood cell-coated nanoparticles showcased a broad capacity to absorb bacterial and environmental toxins from serum. Tailoring the membrane coating to immune cell sources imparts unique characteristics to the nanoparticles suitable for broader application in infectious disease. Their capacity to bind both inflammatory signals and virulence factors assembles the most promising sepsis therapies into a singular, pathogen-agnostic therapeutic. This review explores the ongoing work on immune cell-coated nanoparticle therapeutics for infection and sepsis. SIGNIFICANCE STATEMENT: Invasive bacterial infections and sepsis are a major global health problem made worse by expanding antibiotic resistance, meaning better treatment options are urgently needed. Biomimetic cell-membrane-coated nanoparticles are an innovative therapeutic platform that deploys a multifaceted mechanism to action to neutralize microbial virulence factors, capture endotoxins, and bind excessive host proinflammatory cytokines, seeking to reduce host tissue injury, aid in microbial clearance, and improve patient outcomes.

Abstract
BACKGROUND AND OBJECTIVES This study aimed to identify predictors of sepsis-associated in-hospital mortality from readily available laboratory biomarkers at onset of illness that include haematological, coagulation, liver and kidney function, blood lipid, cardiac enzymes and arterial blood gas. METHODS Children with sepsis were enrolled consecutively in a prospective observational study involving paediatric intensive care units (PICUs) of two hospitals in Beijing, between November 2016 and January 2020. The data on demographics, laboratory examinations during the first 24 hours after PICU admission, complications and outcomes were collected. We screened baseline laboratory indicators using the Least Absolute Shrinkage and Selection Operator (LASSO) analysis, then we constructed a mortality risk model using Cox proportional hazards regression analysis. The ability of risk factors to predict in-hospital mortality was evaluated by receiver operating characteristic (ROC) curves. RESULTS A total of 266 subjects were enrolled including 44 (16.5%) deaths and 222 (83.5%) survivors. Those who died showed a shorter length of hospitalisation, and a higher proportion of mechanical ventilation, complications and organ failure (p<0.05). LASSO analysis identified 13 clinical parameters related to prognosis, which were included in the final Cox model. An elevated triglyceride (TG) remained the most significant risk factor of death (HR=1.469, 95% CI: 1.010 to 2.136, p=0.044), followed by base excess (BE) (HR=1.131, 95% CI: 1.046 to 1.223, p=0.002) and pH (HR=0.95, 95% CI: 0.93 to 0.97, p<0.001). The results of the ROC curve showed that combined diagnosis of the three indicators-TG+BE+pH-has the best area under the curve (AUC) (AUC=0.77, 95% CI: 0.69 to 0.85, p<0.001), with a 68% sensitivity and 80% specificity. CONCLUSION Laboratory factors of TG, BE and pH during the first 24 hours after intensive care unit admission are associated with in-hospital mortality in PICU patients with sepsis. The combination of the three indices has high diagnostic value.

Abstract
OBJECTIVES Acute brain dysfunction (ABD) in pediatric sepsis has a prevalence of 20%, but can be difficult to identify. Our previously validated ABD computational phenotype (CPABD) used variables obtained from the electronic health record indicative of clinician concern for acute neurologic or behavioral change. We tested whether the CPABD has better diagnostic performance to identify confirmed ABD than other definitions using the Glasgow Coma Scale or delirium scores. DESIGN Diagnostic testing in a curated cohort of pediatric sepsis/septic shock patients. SETTING Quaternary freestanding children's hospital. SUBJECTS The test dataset comprised 527 children with sepsis/septic shock managed between 2011 and 2021 with a prevalence (pretest probability) of confirmed ABD of 30% (159/527). MEASUREMENTS AND MAIN RESULTS CPABD was based on use of neuroimaging, electroencephalogram, and/or administration of new antipsychotic medication. We compared the performance of the CPABD with three GCS/delirium-based definitions of ABD-Proulx et al, International Pediatric Sepsis Consensus Conference, and Pediatric Organ Dysfunction Information Update Mandate. The posttest probability of identifying ABD was highest in CPABD (0.84) compared with other definitions. CPABD also had the highest sensitivity (83%; 95% CI, 76-89%) and specificity (93%; 95% CI, 90-96%). The false discovery rate was lowest in CPABD (1-in-6) as was the false omission rate (1-in-14). Finally, the prevalence threshold for the definitions varied, with the CPABD being the definition closest to 20%. CONCLUSIONS In our curated dataset of pediatric sepsis/septic shock, CPABD had favorable characteristics to identify confirmed ABD compared with GCS/delirium-based definitions. The CPABD can be used to further study the impact of ABD in studies using large electronic health datasets.

Abstract
OBJECTIVES Sepsis is one of the leading causes of mortality in the paediatric population. However, knowledge is limited around morbidity in childhood sepsis survivors. The aim of this review is to identify and critically appraise the evidence for long-term outcomes in paediatric survivors of sepsis using the Post Intensive Care Syndrome - paediatrics (PICS-p) framework. METHODS A search for studies was undertaken in the electronic databases PubMed and Cumulative Index to Nursing and Allied Health Literature from 2010. Criteria for inclusion are as follows: participants >28 d adjusted age, diagnosed with sepsis, and follow-up after hospital discharge using a validated outcome measure. The PICS-p subdomains (cognitive, physical, emotional, and social) guided thematic synthesis of current literature. Study quality was assessed using the Newcastle-Ottawa Scale. RESULTS In total, nine studies, involving 2136 children, using 13 different outcome measures were included in the review. Mean follow-up time was 28 d after hospital discharge with a range of 7 d to 12 m across the PICS-p domains. Physical functioning was the most examined domain explored in six studies that used four outcome measures. Morbidity in physical, cognitive, and emotional domains was still evident at 9-12 m. No literature identified explored social health. CONCLUSION(S) Overall, we identified a wide range of measures, administered at various time points in studies of sepsis survivorship in childhood. Variation in follow-up timepoints, validated tools, and restricted outcome measures highlighted the lack in understanding of this priority area. Furthermore, long-term outcome research and a cohesive understanding across all the PICS-p domains are needed to better understand this population. REGISTRATION Not registered.

Abstract
Recognizing immune dysregulation as a hallmark of sepsis pathophysiology, leukocytes have attracted major attention of investigation. While adult and pediatric sepsis are clinically distinct, their immunological delineation remains limited. Single cell technologies facilitated the characterization of immune signatures. We tackled to delineate immunological profiles of pediatric sepsis at a single-cell level by analyzing blood samples from six septic children, at both acute and recovery phases, and four healthy children. 16 single-cell transcriptomic datasets were analyzed and compared to adult sepsis dataset. We showed a unique shift in neutrophil subpopulations and functions between acute and recovery phases, along with the regulatory role of resistin. Neutrophil signatures were comparable between adult and pediatric sepsis. Innate-like CD4 T cells were predominantly and uniquely observed in acute phase of pediatric sepsis. Our study serves as a rich source of information about the phenotypic diversity and trajectory of circulating immune cells during pediatric sepsis.

Abstract
OBJECTIVES To describe the epidemiological characteristics of pediatric sepsis in Southwest China PICUs. DESIGN A prospective, multicenter, and observational study. SETTING Twelve PICUs in Southwest China. PATIENTS The patients admitted to the PICU from April 1, 2022, to March 31, 2023. The age ranged from 28 days to 18 years. All patients met the criteria of severe sepsis or septic shock. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Of the 31 PICUs invited to participate, 12 PICUs (capacity of 292 beds) enrolled patients in the study. During the study period, 11,238 children were admitted to the participating PICUs, 367 (3.3%) of whom met the diagnosis of severe sepsis or septic shock. The most prevalent sites of infection were the respiratory system (55%) and the digestive system (15%). The primary treatments administered to these patients included antibiotics (100%), albumin (61.3%), invasive mechanical ventilation (58.7%), glucocorticoids (55.6%), blood products (51%), gammaglobulin (51%), and vasoactive medications (46.6%). Sepsis-related mortality in the PICU was 11.2% (41/367). Nearly half of the sepsis deaths occurred within the first 3 days of PICU admission (22/41, 53.7%). The mortality rate of septic shock (32/167, 19.2%) was significantly higher than that of severe sepsis (9/200, 4.5%; p < 0.001). The outcomes of a multivariate logistic regression analysis suggested that a higher pediatric Sequential Organ Failure Assessment score, and the use of invasive mechanical ventilation and vasoactive medications were independently associated with PICU mortality in children with sepsis. CONCLUSIONS This report updates the epidemiological data of pediatric sepsis in PICUs in Southwest China. Sepsis is still a life-threatening disease in children.

Abstract
Background pRIFLE (Pediatric Risk, Injury, Failure, Loss, End Stage Renal Disease), KDIGO (Kidney Disease Improving Global Outcomes) and pROCK (Pediatric Reference Change Value Optimized for AKI) are diagnostic criteria used for acute kidney injury (AKI) incidence evaluation. The aim of this study was to explore the diagnostic consistency, incidence and mortality rate, clinical signs, and influencing factors of renal injury related to sepsis in children diagnosed by three different AKI diagnostic criteria, and then evaluate which one was more valuable. Methods A retrospective analysis was performed on the clinical data of children with severe sepsis. The patients were diagnosed and staged according to the 2007 pRIFLE standard, the 2012 KDIGO standard, and the 2018 pROCK standard. The clinical characteristics and prognosis of children with different stages of sepsis were compared between the three diagnostic standards. Results A total of 62 patients with sepsis were included. Blood stream infection is common (11 cases, 17.74%). According to pRIFLE, KDIGO, and pROCK standards, the incidence of sepsis-associated AKI (SA-AKI) was 74.2%, 67.7%, and 56.5%, respectively. The pRIFLE had the highest diagnostic rate of early detection of SA-AKI. There was no statistical difference in SA-AKI incidence or staging consistency between the pRIFLE and KDIGO groups (κ=0.0671; κ>0.60); the consistency of SA-AKI diagnoses across the three standards was good (all P values <0.05), and pROCK demonstrated a higher specificity. A high Pediatric Risk of Mortality (PRISM) score and high procalcitonin level were independent risk factors. Shock and renal replacement therapy were independent risk factors for SA-AKI death. Death from admission to 28 days after admission was used as an endpoint to draw a survival graph, which revealed that the AKI group had a significantly higher risk of death than did the non-AKI group. Conclusions The consistency of diagnosing SA-AKI across the three classification criteria was similar, and mortality rate increased with increased SA-AKI staging. The pRIFLE criteria were more sensitive in the early detection of SA-AKI, while the pROCK had higher specificity. There was no significant difference between the pRIFLE and KDIGO in terms of incidence, diagnosis, or staging of SA-AKI.

Abstract
Objective Sepsis in pediatric patients can progress to severe sepsis, and identifying biomarkers of this progression may permit timely intervention to prevent it. This study aimed to investigate the ability of thrombin-antithrombin complex (TAT), α2-plasmininhibitor-plasmin complex (PIC) and tissue-type plasminogen activator-inhibitor complex (t-PAIC) to predict severe sepsis in pediatrics early. Methods 148 eligible pediatric sepsis patients were enrolled in this study, and were then divided into those who progressed to severe sepsis (n = 50) or not (n = 98). Serum levels of TAT, PIC, and t-PAIC were analysed, and simplified pediatric critical illness score (PCIS) and DIC score were calculated on the day of pediatric sepsis diagnosis. Results Compared with sepsis patients, severe sepsis patients had higher levels of TAT, PIC and t-PAIC. Correlation analysis revealed that TAT, PIC and t-PAIC were significantly correlated with simplified PCIS and DIC score. ROC curve analysis suggested that TAT, PIC and t-PAIC could serve as biomarkers for predicting severe sepsis with the AUC up to 0.862, 0.759 and 0.851, respectively. Stratified analysis demonstrated that the patients with increased levels of TAT, PIC and t-PAIC had worse illness severity and clinical outcome. Univariate logistic regression analysis revealed that TAT, PIC and t-PAIC were all risk factors for severe sepsis, yet only TAT and t-PAIC were independent risk factors in multivariate model. Conclusions TAT, PIC and t-PAIC could serve as biomarkers for predicting severe sepsis, and correlated with illness severity in pediatrics, what's more, serum levels of TAT and t-PAIC may be independent risk factors for pediatric severe sepsis.

Abstract
BACKGROUND Paediatric sepsis is the leading cause of death in children under 5 years. No studies have evaluated the application of the Surviving Sepsis Campaign 2020 (SSC-2020) guidelines in paediatric emergency departments (PEDs). OBJECTIVE To assess physician adherence to the SSC-2020 fluid resuscitation guidelines in children with suspected septic shock in PEDs. METHODS This was a prospective multicentre observational study conducted in 21 French hospitals over 5 sequential weeks, between November 2021 and March 2022. Children with suspected septic shock and who received antimicrobial therapy within 72 hours were included. Primary outcome was SSC-2020 fluid resuscitation guidelines adherence (low 0-24%; moderate 25-74%; high 75-100%) according to: bolus volume of 10-20 mL/kg each, exclusive administration of balanced crystalloids at 1 and 24 hours of management, and initiation of fluid resuscitation within 1 hour of septic shock recognition. RESULTS 63 children were included. 10 (16%) children had severe sepsis and 2 (3%) met the definition of septic shock. Compared with the SSC-2020 guidelines, 43 (68%) patients received boluses of 10-20 mL/kg; fluid resuscitation was initiated within 1 hour of septic shock recognition in 42 (76%) cases; balanced crystalloids were the only fluids administrated in 35 (56%) and 34 (55%) children at 1 and 24 hours of management, respectively. Main barriers reported by physicians were difficult intravenous access (43%), lack of team training (29%), workload constraints (28%), and absence or out-of-date protocols (24%). CONCLUSIONS This study found high adherence for fluid resuscitation initiation but moderate adherence for bolus volume and fluid choice. TRIAL REGISTRATION NUMBER NCT05066464.

Abstract
OBJECTIVE Pediatric sepsis screening is becoming the standard of care for children presenting to the emergency department (ED) and has been shown to improve recognition of severe sepsis, but it is unknown if these screening tools can predict progression of disease. The objective of this study was to determine if any elements of a sepsis triage trigger tool were predictive of progression to hypotensive shock in children presenting to the ED with fever and tachycardia. METHODS This study is a retrospective case-control study of children ≤18 years presenting to an ED with fever and tachycardia, comparing those who went on to develop hypotensive shock in the subsequent 24 hours (case) to those who did not (control). Primary outcome was the proportion of encounters where the patient had specific abnormal vital signs or clinical signs as components of the sepsis triage score. The secondary outcomes were the proportion of encounters where the patient had a sepsis risk factor. RESULTS During the study period, there were 94 patients who met case criteria and 186 controls selected. In the adjusted multivariable model, the 2 components of the sepsis triage score that were more common in case patients were the presence of severe cerebral palsy (adjusted odds ratio, 9.4 [3.7, 23.9]) and abnormal capillary refill at triage (adjusted odds ratio, 3.1 [1.4, 6.9]). CONCLUSIONS Among children who present to a pediatric ED with fever and tachycardia, those with prolonged capillary refill at triage or severe cerebral palsy were more likely to progress to decompensated septic shock, despite routine ED care.

Abstract
OBJECTIVES Previous studies applying Sepsis-3 criteria to children were based on retrospective analyses of PICU cohorts. We aimed to compare organ dysfunction criteria in children with blood culture-proven sepsis, including emergency department, PICU, and ward patients, and to assess relevance of organ dysfunctions for mortality prediction. DESIGN We have carried out a nonprespecified, secondary analysis of a prospective dataset collected from September 2011 to December 2015. SETTING Emergency departments, wards, and PICUs in 10 tertiary children's hospitals in Switzerland. PATIENTS Children younger than 17 years old with blood culture-proven sepsis. We excluded preterm infants and term infants younger than 7 days old. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We compared the 2005 International Pediatric Sepsis Consensus Conference (IPSCC), Pediatric Logistic Organ Dysfunction-2 (PELOD-2), pediatric Sequential Organ Failure Assessment (pSOFA), and Pediatric Organ Dysfunction Information Update Mandate (PODIUM) scores, measured at blood culture sampling, to predict 30-day mortality. We analyzed 877 sepsis episodes in 807 children, with a 30-day mortality of 4.3%. Percentage with organ dysfunction ranged from 32.7% (IPSCC) to 55.3% (pSOFA). In adjusted analyses, the accuracy for identification of 30-day mortality was area under the curve (AUC) 0.87 (95% CI, 0.82-0.92) for IPSCC, 0.83 (0.76-0.89) for PELOD-2, 0.85 (0.78-0.92) for pSOFA, and 0.85 (0.78-0.91) for PODIUM. When restricting scores to neurologic, respiratory, and cardiovascular dysfunction, the adjusted AUC was 0.89 (0.84-0.94) for IPSCC, 0.85 (0.79-0.91) for PELOD-2, 0.87 (0.81-0.93) for pSOFA, and 0.88 (0.83-0.93) for PODIUM. CONCLUSIONS IPSCC, PELOD-2, pSOFA, and PODIUM performed similarly to predict 30-day mortality. Simplified scores restricted to neurologic, respiratory, and cardiovascular dysfunction yielded comparable performance.

Abstract
BACKGROUND Globally, sepsis has been identified as one of the leading causes of preventable childhood mortality and morbidity. Previous studies on intensive care patients estimated that approximately 30% of children with sepsis experience some form of disability at discharge. Development of care has seen growing numbers of children treated for sepsis not requiring a PICU admission; however, outcomes in this population are yet to be understood. Further focus is required to understand sepsis survivorship across the wider population to address knowledge gaps and morbidity burden in the broader surviving population. AIMS To assess the cognitive, physical, emotional and social health of children surviving sepsis 2 years after hospital discharge. STUDY DESIGN A prospective, observational cohort study. RESULTS Two hundred and thirty-two children will be screened, 2 years after their hospital admission, and approached for participation in this study. Children who are <18 years of age at follow-up, treated for sepsis-related organ dysfunction or septic shock in Queensland between October 2018 and December 2019, will be included. Children who are deceased at follow-up, under care of the state, or require English interpreters will be excluded from participation. Data will be collected through an online follow-up survey comprising validated caregiver-reported questionnaires covering the four Post Intensive Care Syndrome-paediatrics (PICS-p) domains (cognitive, physical, emotional and social health; Manning et al. Pediatr Crit Care Med, 2018, 19, 298-300). The primary outcome is an adaptive behaviour of the participants assessed using the Vinelands-3 tool. Secondary outcomes will include neurodevelopment, quality of life, child distress, overall function, executive function, caregiver's distress and caregiver's stress. Analysis of variance (ANOVA), Kruskal-Wallis and Fisher's exact test/chi-squared tests will be used for statistical analyses. No adjustments will be made for multiple comparisons but it is acknowledged that comparisons made in this study are exploratory. RELEVANCE TO CLINICAL PRACTICE With more children surviving sepsis, there is a need for a more comprehensive assessment of patient and family outcomes to allow support structures for families leaving the hospital after sepsis. This study is expected to inform clinicians and stakeholders of patient and family well-being after sepsis survivorship.

Abstract
Nutritional practice in children with severe sepsis or septic shock remains poorly described. We aimed to describe nutrition received by children with severe sepsis or septic shock and explore the association of nutritional intake with clinical outcomes. This study was a retrospective study of children who required pediatric intensive care unit (PICU) admission from 2009 to 2016. Outcomes were mortality, ventilator-free days (VFDs), and PICU-free days (IFDs). A total of 74 patients with septic shock or severe sepsis were identified. Forty-one (55.4%) patients received enteral nutrition (EN) only, 6 (8.1%) patients received parental nutrition (PN) only, 15 (20.3%) patients received both EN and PN, and 12 (16.2%) patients received intravenous fluids alone. Eight of 74 (10.8%) and 4 of 74 (5.4%) had adequate energy and protein intake, respectively. Patients who received early EN had lower odds of 28-day mortality (adjusted hazard ratio [HR] = 0.09, 95% confidence interval [CI]: 0.02, 0.45, p = 0.03) more 28-day VFDs (adjusted β-coefficient = 18.21 [95% CI: 11.11, 25.32], p < 0.001), and IFDs (adjusted ß-coefficient = 16.71 [95% CI: 9.86, 23.56], p < 0.001) than patients who did not receive EN. Late EN was also associated with lower odds of mortality, more VFDs, and IFDs compared with no EN (HR = 0.06, 95% CI: 0.02, 0.23; p < 0.001; adjusted β coefficient = 15.66, 95% CI: 9.31, 22.02; p < 0.001; and 12.34 [95% CI: 6.22, 18.46], p < 0.001; respectively). Inadequate calories and protein were not associated with mortality. EN in children with septic shock or severe sepsis was associated with improved clinical outcomes. Future prospective studies are required to explore the impact of EN timing and optimal nutritional intake in these children.

Abstract
OBJECTIVE Studies focusing on bone and joint infections (BJIs) in young infants are rare. Some cases of BJI are accompanied by sepsis. This study aimed to identify the clinical and bacteriological features of sepsis in neonates and young infants with BJIs. METHODS Neonates and infants younger than 3 months diagnosed with BJI in the present institution from 2014 to 2021 were retrospectively reviewed. Patient characteristics, clinical data, and outcomes were documented and compared between those with and without sepsis. RESULTS Twenty-five patients with a mean age of 34.8 days were included. Nine BJI cases had concomitant sepsis (group A), and 16 had BJI without sepsis (group B). Within group A, staphylococcus aureus was the major pathogenic germ (5 cases, of which 4 were of the methicillin-resistant staphylococcus aureus (MRSA) type). There was no statistical difference in male-to-female ratio, age, history of hospitalization, anemia, birth asphyxia, peripheral leukocyte counts, C-reactive protein on admission, and sequelae between groups. Univariate analyses indicated a significant difference in the incidence of septic arthritis (SA) combined with osteomyelitis (OM) (88.9% vs 37.5%), congenital deformities (44.4% vs 0%), and mean duration of symptoms (2.83 days vs 9.21 days) in comparisons between groups A and B. CONCLUSION Staphylococcus aureus is the main pathogenic bacteria in BJI cases complicated with sepsis in neonates and young infants. Among infants younger than 3 months diagnosed with BJI, those with concurrent SA and OM, MRSA infection, or congenital deformities are more likely to develop sepsis.

Abstract
INTRODUCTION Sepsis is a leading cause of pediatric mortality. While there has been significant effort toward improving adherence to evidence-based care, gaps remain. Immersive multiuser virtual reality (MUVR) simulation may be an approach to enhance provider clinical competency and situation awareness for sepsis. METHODS A prospective, observational pilot of an interprofessional MUVR simulation assessing a decompensating patient from sepsis was conducted from January to June 2021. The study objective was to establish validity and acceptability evidence for the platform by assessing differences in sepsis recognition between experienced and novice participants. Interprofessional teams assessed and managed a patient together in the same VR experience with the primary outcome of time to recognition of sepsis utilizing the Situation Awareness Global Assessment Technique analyzed using a logistic regression model. Secondary outcomes were perceived clinical accuracy, relevancy to practice, and side effects experienced. RESULTS Seventy-two simulations included 144 participants. The cumulative odds ratio of recognizing sepsis at 2 min into the simulation in comparison to later time points by experienced versus novice providers were significantly higher with a cumulative odds ratio of 3.70 (95% confidence interval: 1.15-9.07, p = .004). Participants agreed that the simulation was clinically accurate (98.6%) and will impact their practice (81.1%), with a high degree of immersion (95.7%-99.3%), and the majority of side effects were perceived as mild (70.4%-81.4%). CONCLUSIONS Our novel MUVR simulation demonstrated significant differences in sepsis recognition between experienced and novice participants. This validity evidence along with the data on the simulation's acceptability supports expanded use in training and assessment.

Abstract
OBJECTIVES To evaluate the knowledge, attitudes and practices towards diagnosing and managing paediatric sepsis among paediatric physicians and nurses. DESIGN A cross-sectional, questionnaire-based study. SETTING 21 hospitals in Hubei Province between February 2023 and March 2023. PARTICIPANTS Paediatric physicians and nurses. INTERVENTIONS None. PRIMARY AND SECONDARY OUTCOME MEASURES The questionnaire contained 35 items across four dimensions (demographic information, knowledge, attitude and practice). RESULTS The study included 295 participants (173 women). The average knowledge, attitude and practice scores were 10.93±2.61 points (possible range, 0-20 points), 32.22±2.65 points (possible range, 7-35 points) and 36.54±5.24 points (possible range, 9-45 points), respectively. Knowledge had a direct influence on both attitude (β=0.240, 95% CI 0.136 to 0.365, p=0.009) and practice (β=0.278, 95% CI 0.084 to 0.513, p=0.010), which also indirectly influenced practice through attitude (β=0.162, 95% CI 0.078 to 0.290, p=0.007). Attitude directly influenced practice (β=0.677, 95% CI 0.384 to 0.902, p=0.025). A higher attitude score was associated with good practice (OR=1.392; 95% CI 1.231 to 1.576; p<0.001), while not working in a tertiary hospital reduced the odds of good practice (OR=0.443; 95% CI 0.2390.821; p=0.010). CONCLUSIONS The knowledge regarding paediatric sepsis, especially knowledge about sepsis management, is poor among paediatric physicians and nurses in Hubei Province. The findings of this study may facilitate the development and implementation of training programmes to improve the diagnosis and management of paediatric sepsis.

Abstract
Importance Sepsis is a leading cause of death among children worldwide. Current pediatric-specific criteria for sepsis were published in 2005 based on expert opinion. In 2016, the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) defined sepsis as life-threatening organ dysfunction caused by a dysregulated host response to infection, but it excluded children. Objective To update and evaluate criteria for sepsis and septic shock in children. Evidence Review The Society of Critical Care Medicine (SCCM) convened a task force of 35 pediatric experts in critical care, emergency medicine, infectious diseases, general pediatrics, nursing, public health, and neonatology from 6 continents. Using evidence from an international survey, systematic review and meta-analysis, and a new organ dysfunction score developed based on more than 3 million electronic health record encounters from 10 sites on 4 continents, a modified Delphi consensus process was employed to develop criteria. Findings Based on survey data, most pediatric clinicians used sepsis to refer to infection with life-threatening organ dysfunction, which differed from prior pediatric sepsis criteria that used systemic inflammatory response syndrome (SIRS) criteria, which have poor predictive properties, and included the redundant term, severe sepsis. The SCCM task force recommends that sepsis in children be identified by a Phoenix Sepsis Score of at least 2 points in children with suspected infection, which indicates potentially life-threatening dysfunction of the respiratory, cardiovascular, coagulation, and/or neurological systems. Children with a Phoenix Sepsis Score of at least 2 points had in-hospital mortality of 7.1% in higher-resource settings and 28.5% in lower-resource settings, more than 8 times that of children with suspected infection not meeting these criteria. Mortality was higher in children who had organ dysfunction in at least 1 of 4-respiratory, cardiovascular, coagulation, and/or neurological-organ systems that was not the primary site of infection. Septic shock was defined as children with sepsis who had cardiovascular dysfunction, indicated by at least 1 cardiovascular point in the Phoenix Sepsis Score, which included severe hypotension for age, blood lactate exceeding 5 mmol/L, or need for vasoactive medication. Children with septic shock had an in-hospital mortality rate of 10.8% and 33.5% in higher- and lower-resource settings, respectively. Conclusions and Relevance The Phoenix sepsis criteria for sepsis and septic shock in children were derived and validated by the international SCCM Pediatric Sepsis Definition Task Force using a large international database and survey, systematic review and meta-analysis, and modified Delphi consensus approach. A Phoenix Sepsis Score of at least 2 identified potentially life-threatening organ dysfunction in children younger than 18 years with infection, and its use has the potential to improve clinical care, epidemiological assessment, and research in pediatric sepsis and septic shock around the world.

Abstract
OBJECTIVE Among children treated for sepsis in a pediatric emergency department (ED), compare clinical features and outcomes between those with blood cultures positive versus negative for a bacterial pathogen. DESIGN Single-center retrospective cohort study. SETTING Pediatric emergency department (ED) at a quaternary pediatric care center. PATIENTS Children aged 0-18 years treated for sepsis defined by the Children's Hospital Association's Improving Pediatric Sepsis Outcomes (IPSO) definition. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We analyzed 1307 patients treated for sepsis during the study period, of which 117 (9.0%) had blood cultures positive for a bacterial pathogen. Of children with blood culture positive sepsis, 62 (53.0%) had organ dysfunction compared to 514 (43.2%) with culture negative sepsis (adjusted odds ratio 1.56, 95% confidence interval (CI) 1.04-2.34, adjusting for age, high risk medical conditions, and time to antibiotics). Children with blood culture positive sepsis had a larger base deficit, -4 vs -1 (p < 0.01), and higher procalcitonin, 3.84 vs 0.56 ng/mL (p < 0.01). CONCLUSIONS Children meeting the IPSO Sepsis definition with blood culture positive for a bacterial pathogen have higher rates of organ dysfunction than those who are culture negative, although our 9% rate of blood culture positivity is lower than previously cited literature from the pediatric intensive care unit.

Abstract
The true global burden of paediatric critical illness remains unknown. Studies on children with life-threatening conditions are hindered by the absence of a common definition for acute paediatric critical illness (DEFCRIT) that outlines components and attributes of critical illness and does not depend on local capacity to provide critical care. We present an evidence-informed consensus definition and framework for acute paediatric critical illness. DEFCRIT was developed following a scoping review of 29 studies and key concepts identified by an interdisciplinary, international core expert panel (n=24). A modified Delphi process was then done with a panel of multidisciplinary health-care global experts (n=109) until consensus was reached on eight essential attributes and 28 statements as the basis of DEFCRIT. Consensus was reached in two Delphi rounds with an expert retention rate of 89%. The final consensus definition for acute paediatric critical illness is: an infant, child, or adolescent with an illness, injury, or post-operative state that increases the risk for or results in acute physiological instability (abnormal physiological parameters or vital organ dysfunction or failure) or a clinical support requirement (such as frequent or continuous monitoring or time-sensitive interventions) to prevent further deterioration or death. The proposed definition and framework provide the conceptual clarity needed for a unified approach for global research across resource-variable settings. Future work will centre on validating DEFCRIT and determining high priority measures and guidelines for data collection and analysis that will promote its use in research.

Abstract
Introduction: Pediatric sepsis (PS) is a life-threatening infection associated with high mortality rates, necessitating a deeper understanding of its underlying pathological mechanisms. Recently discovered programmed cell death induced by copper has been implicated in various medical conditions, but its potential involvement in PS remains largely unexplored. Methods: We first analyzed the expression patterns of cuproptosis-related genes (CRGs) and assessed the immune landscape of PS using the GSE66099 dataset. Subsequently, PS samples were isolated from the same dataset, and consensus clustering was performed based on differentially expressed CRGs. We applied weighted gene co-expression network analysis to identify hub genes associated with PS and cuproptosis. Results: We observed aberrant expression of 27 CRGs and a specific immune landscape in PS samples. Our findings revealed that patients in the GSE66099 dataset could be categorized into two cuproptosis clusters, each characterized by unique immune landscapes and varying functional classifications or enriched pathways. Among the machine learning approaches, Extreme Gradient Boosting demonstrated optimal performance as a diagnostic model for PS. Discussion: Our study provides valuable insights into the molecular mechanisms underlying PS, highlighting the involvement of cuproptosis-related genes and immune cell infiltration.

Abstract
Recognizing immune dysregulation as a hallmark of sepsis pathophysiology, leukocytes have attracted major attention of investigation. While adult and pediatric sepsis are clinically distinct, their immunological delineation remains limited. Breakthrough of single cell technologies facilitated the characterization of immune signatures. We tackled to delineate immunological profiles of pediatric sepsis at a single-cell level by analyzing blood samples from six septic children, at both acute and recovery phases, and four healthy children. 16 single-cell transcriptomic datasets (96,156 cells) were analyzed and compared to adult sepsis dataset. We showed a unique shift in neutrophil subpopulations and functions between acute and recovery phases, along with examining the regulatory role of resistin. Neutrophil signatures were comparable between adult and pediatric sepsis. Innate-like CD4 T cells were predominantly and uniquely observed in acute phase of pediatric sepsis. Our study provides a thorough and comprehensive understanding of immune dysregulation in pediatric sepsis.

Abstract
Neutrophils, the most abundant type of white blood cells, are pivotal in fighting bacterial infections due to their immunological and anti-infection capabilities. In recent years, scientists have discovered a novel mechanism known as neutrophil extracellular traps, which are fibrous networks primarily released by neutrophils that combat bacterial infections. There is a growing interest in studying NETs and their role in human infectious diseases, particularly in neonates susceptible to bacterial infections. NETs and their components have been found in various samples from neonatal-infected patients, providing a new route for early diagnosis of neonatal infectious diseases. This paper aims to summarize the studies on NETs in adult diseases and mainly discuss NETs in neonatal sepsis, necrotizing enterocolitis, and purulent meningitis, to provide scientific evidence for early monitoring, diagnosis, and treatment of neonatal infections.

Abstract
INTRODUCTION Sepsis affects 25.2 million children per year globally and causes 3.4 million deaths, with an annual cost of hospitalisation in the USA of US$7.3 billion. Despite being common, severe and expensive, therapies and outcomes from sepsis have not substantially changed in decades. Variable case definitions, lack of a reference standard for diagnosis and broad spectrum of disease hamper efforts to evaluate therapies that may improve sepsis outcomes. This landscape analysis of community-acquired childhood sepsis in Australia and New Zealand will characterise the burden of disease, including incidence, severity, outcomes and cost. Sepsis diagnostic criteria and risk stratification tools will be prospectively evaluated. Sepsis therapies, quality of care, parental awareness and understanding of sepsis and parent-reported outcome measures will be described. Understanding these aspects of sepsis care is fundamental for the design and conduct of interventional trials to improve childhood sepsis outcomes. METHODS AND ANALYSIS This prospective observational study will include children up to 18 years of age presenting to 12 emergency departments with suspected sepsis within the Paediatric Research in Emergency Departments International Collaborative network in Australia and New Zealand. Presenting characteristics, management and outcomes will be collected. These will include vital signs, serum biomarkers, clinician assessment of severity of disease, intravenous fluid administration for the first 24 hours of hospitalisation, organ support therapies delivered, antimicrobial use, microbiological diagnoses, hospital and intensive care unit length-of-stay, mortality censored at hospital discharge or 30 days from enrolment (whichever comes first) and parent-reported outcomes 90 days from enrolment. We will use these data to determine sepsis epidemiology based on existing and novel diagnostic criteria. We will also validate existing and novel sepsis risk stratification criteria, characterise antimicrobial stewardship, guideline adherence, cost and report parental awareness and understanding of sepsis and parent-reported outcome measures. ETHICS AND DISSEMINATION Ethics approval was received from the Royal Children's Hospital of Melbourne, Australia Human Research Ethics Committee (HREC/69948/RCHM-2021). This included incorporated informed consent for follow-up. The findings will be disseminated in a peer-reviewed journal and at academic conferences.

Abstract
ABSTRACT Background: Multiple-organ dysfunction syndrome disproportionately contributes to pediatric sepsis morbidity. Humanin (HN) is a small peptide encoded by mitochondrial DNA and thought to exert cytoprotective effects in endothelial cells and platelets. We sought to test the association between serum HN (sHN) concentrations and multiple-organ dysfunction syndrome in a prospectively enrolled cohort of pediatric septic shock. Methods: Human MT-RNR2 ELISA was used to determine sHN concentrations on days 1 and 3. The primary outcome was thrombocytopenia-associated multiorgan failure (TAMOF). Secondary outcomes included individual organ dysfunctions on day 7. Associations across pediatric sepsis biomarker (PERSEVERE)-based mortality risk strata and correlation with platelet and markers of endothelial activation were tested. Results: One hundred forty subjects were included in this cohort, of whom 39 had TAMOF. The concentration of sHN was higher on day 1 relative to day 3 and among those with TAMOF phenotype in comparison to those without. However, the association between sHN and TAMOF phenotype was not significant after adjusting for age and illness severity in multivariate models. In secondary analyses, sHN was associated with presence of day 7 sepsis-associated acute kidney injury ( P = 0.049). Furthermore, sHN was higher among those with high PERSEVERE-mortality risk strata and correlated with platelet counts and several markers of endothelial activation. Conclusion: Future investigation is necessary to validate the association between sHN and sepsis-associated acute kidney injury among children with septic shock. Furthermore, mechanistic studies that elucidate the role of HN may lead to therapies that promote organ recovery through restoration of mitochondrial homeostasis among those critically ill.

Abstract
BACKGROUND Multiple organ dysfunction syndrome (MODS) disproportionately drives morbidity and mortality among critically ill patients. However, we lack a comprehensive understanding of its pathobiology. Identification of genes associated with a persistent MODS trajectory may shed light on underlying biology and allow for accurate prediction of those at-risk. METHODS Secondary analyses of publicly available gene-expression datasets. Supervised machine learning (ML) was used to identify a parsimonious set of genes associated with a persistent MODS trajectory in a training set of pediatric septic shock. We optimized model parameters and tested risk-prediction capabilities in independent validation and test datasets, respectively. We compared model performance relative to an established gene-set predictive of sepsis mortality. FINDINGS Patients with a persistent MODS trajectory had 568 differentially expressed genes and characterized by a dysregulated innate immune response. Supervised ML identified 111 genes associated with the outcome of interest on repeated cross-validation, with an AUROC of 0.87 (95% CI: 0.85-0.88) in the training set. The optimized model, limited to 20 genes, achieved AUROCs ranging from 0.74 to 0.79 in the validation and test sets to predict those with persistent MODS, regardless of host age and cause of organ dysfunction. Our classifier demonstrated reproducibility in identifying those with persistent MODS in comparison with a published gene-set predictive of sepsis mortality. INTERPRETATION We demonstrate the utility of supervised ML driven identification of the genes associated with persistent MODS. Pending validation in enriched cohorts with a high burden of organ dysfunction, such an approach may inform targeted delivery of interventions among at-risk patients.

Abstract
Sepsis and septic shock are major causes of morbidity, mortality, and health care costs for children worldwide, including >3 million deaths annually and, among survivors, risk for new or worsening functional impairments, including reduced quality of life, new respiratory, nutritional, or technological assistance, and recurrent severe infections. Advances in understanding sepsis pathophysiology highlight a need to update the definition and diagnostic criteria for pediatric sepsis and septic shock, whereas new data support an increasing role for automated screening algorithms and biomarker combinations to assist earlier recognition. Once sepsis or septic shock is suspected, attention to prompt initiation of broad-spectrum empiric antimicrobial therapy, fluid resuscitation, and vasoactive medications remain key components to initial management with several new and ongoing studies offering new insights into how to optimize this approach. Ultimately, a key goal is for screening to encompass as many children as possible at risk for sepsis and trigger early treatment without increasing unnecessary broad-spectrum antibiotics and preventable hospitalizations. Although the role for adjunctive treatment with corticosteroids and other metabolic therapies remains incompletely defined, ongoing studies will soon offer updated guidance for optimal use. Finally, we are increasingly moving toward an era in which precision therapeutics will bring novel strategies to improve outcomes, especially for the subset of children with sepsis-induced multiple organ dysfunction syndrome and sepsis subphenotypes for whom antibiotics, fluid, vasoactive medications, and supportive care remain insufficient.

Abstract
INTRODUCTION Purpura fulminans (PF) is a serious complication of sepsis resulting from a set of alterations characterised by the development of ecchymotic haemorrhagic lesions and skin necrosis. AIM To analyse the efficacy and safety of the topical application of HOFA compound, in the cutaneous microcirculation of PF lesions in paediatric patients affected by sepsis. MATERIAL AND METHODS A prospective quasi-experimental pre-test/post-test single-group conducted in a Paediatric Intensive Care Unit of a third level hospital was performed. Paediatric patients aged 0-18 years with sepsis were included. Somatic oximetry values were measured before and after application of HOFAs every 4h over the first three days of the patients' hospitalisation. Patient's socio-demographic and clinical variables and somatic oximetry by placing a sensor for measuring tissue perfusion on the area with PF were determined. RESULTS Four patients were recruited, with a median age of 98 months. The purpuric lesions measured were mainly located on both feet and hands and, in two patients, also on the lateral malleoli and calves of both lower extremities. A total of 225 measurements were obtained, with mean pre-intervention scores of 71.17±15.65% versus 73.68±14.83% post-intervention. Statistical significance (p<0.001) was observed upon comparison of the pre- and post-intervention measurements. CONCLUSIONS Early and continued application of HOFAs in the management of sepsis-induced PF is an effective and safe practice in the cases analysed. In more than half of the episodes analysed, an increase in tissue microcirculation was observed after the application of HOFAs, with no adverse events.

Abstract
Objective Sepsis remains a leading cause of morbidity and mortality in children. There is very limited guidance for sepsis treatment when cultures remain negative. This study sought to determine the effectiveness of short versus long course of antibiotics when treating culture-negative sepsis and assess for subsequent multidrug-resistant organism (MDRO) acquisition. Design Retrospective cohort study. Setting Quaternary academic children's hospital. Patients Pediatric intensive care unit (ICU) patients with culture-negative sepsis receiving a minimum of 72 hours of antibiotics. Methods Patients found to have culture-negative sepsis from January 2017 to May 2020 were divided into two groups: short and long course of antibiotics. Various demographic and laboratory results were collected for each subject as available. Primary outcomes included mortality and lengths of stay. The secondary outcome was subsequent acquisition of a new MDRO. Results Eighty-six patients were treated for culture-negative sepsis with 43 patients in both the short- (< or = 7 days) and long-course (>7 days) treatment cohorts. Patients who received a short course of antibiotics had a lower overall mortality than those who received a long course (9.3% vs 25.6% p = 0.047), but there was no difference in 30-day mortality (p > 0.99). Patients in the short-course group had a shorter hospital length of stay (22 vs 30 days p = 0.018). New MDROs were found in 10% of all patients. Conclusions Treatment of culture-negative sepsis with short-course antibiotics was not associated with worse outcomes in ICU patients. These findings warrant further investigation with a larger, prospective, multi-center study.

Abstract
OBJECTIVES Sepsis-associated immune suppression correlates with poor outcomes. Adult trials are evaluating immune support therapies. Limited data exist to support consideration of immunomodulation in pediatric sepsis. We tested the hypothesis that early, persistent lymphopenia predicts worse outcomes in pediatric severe sepsis. DESIGN Observational cohort comparing children with severe sepsis and early, persistent lymphopenia (absolute lymphocyte count < 1,000 cells/µL on 2 d between study days 0-5) to children without. The composite outcome was prolonged multiple organ dysfunction syndrome (MODS, organ dysfunction beyond day 7) or PICU mortality. SETTING Nine PICUs in the National Institutes of Health Collaborative Pediatric Critical Care Research Network between 2015 and 2017. PATIENTS Children with severe sepsis and indwelling arterial and/or central venous catheters. INTERVENTIONS Blood sampling and clinical data analysis. MEASUREMENTS AND MAIN RESULTS Among 401 pediatric patients with severe sepsis, 152 (38%) had persistent lymphopenia. These patients were older, had higher illness severity, and were more likely to have underlying comorbidities including solid organ transplant or malignancy. Persistent lymphopenia was associated with the composite outcome prolonged MODS or PICU mortality (66/152, 43% vs 45/249, 18%; p < 0.01) and its components prolonged MODS (59/152 [39%] vs 43/249 [17%]), and PICU mortality (32/152, 21% vs 12/249, 5%; p < 0.01) versus children without. After adjusting for baseline factors at enrollment, the presence of persistent lymphopenia was associated with an odds ratio of 2.98 (95% CI [1.85-4.02]; p < 0.01) for the composite outcome. Lymphocyte count trajectories showed that patients with persistent lymphopenia generally did not recover lymphocyte counts during the study, had lower nadir whole blood tumor necrosis factor-α response to lipopolysaccharide stimulation, and higher maximal inflammatory markers (C-reactive protein and ferritin) during days 0-3 ( p < 0.01). CONCLUSIONS Children with severe sepsis and persistent lymphopenia are at risk of prolonged MODS or PICU mortality. This evidence supports testing therapies for pediatric severe sepsis patients risk-stratified by early, persistent lymphopenia.

Abstract
OBJECTIVES To compare the outcomes of pediatric severe sepsis and septic shock among patients with culture-positive and culture-negative sepsis and to determine if there are differentiating markers of disease severity between these 2 populations during their initial presentation and emergency department (ED) stay. STUDY DESIGN Retrospective cohort study of patients ≤21 years of age who presented to the ED of a single children's hospital with severe sepsis or septic shock from June 1, 2017 to June 5, 2019. RESULTS There were 235 patients who met criteria for severe sepsis or septic shock. Of these, 139 (59.1%) had culture-negative sepsis and 96 (40.9%) had culture-positive sepsis. In the adjusted multivariable model, children with culture-negative sepsis had more intensive care unit (ICU)-free days than those with culture-positive sepsis (27.3 vs 24.1; adjusted median differences [aMD] -2.6 [-4.4, -0.8]). There were no differences in mortality or hospital-free days. On initial presentation, there were no differences in fever, hypothermia, tachycardia, tachypnea, or hypotension between the 2 groups. There were no differences in proportion of patients receiving the following interventions: intravenous (IV) antibiotics, IV fluids, vasoactive medications, CPR, intubation, or time from arrival to provision of these interventions. CONCLUSIONS Culture-negative sepsis constitutes a substantial proportion of pediatric severe sepsis and septic shock. In this study, patients with culture-negative and culture-positive sepsis presented similarly on arrival to the ED and received similar treatments while there. Patients with culture-negative sepsis had more ICU-free days than those with culture-positive sepsis, although differences in hospital length of stay (LOS) and mortality were not observed.

Abstract
OBJECTIVE To evaluate the performance of existing sepsis scores for prediction of adverse outcomes in children with cancer admitted to the ICU with suspected sepsis. DESIGN Retrospective chart review using data available at 1, 6, 12, and 24 h after ICU admission to calculate the Pediatric Risk of Mortality 3 (PRISM-3), Pediatric Sequential Organ Failure Assessment (pSOFA), Paediatric Logistic Organ Dysfunction 2 (PELOD-2), and Quick Pediatric Sequential Organ Failure Assessment (qSOFA) scores. Area under the receiver operator characteristic curve (AUROC) was used to evaluate performance for prediction of attributable mortality. Sensitivity analyses included recalculation of scores using worst preceding values for each variable, excluding hematologic parameters, and prediction of alternative outcomes. SETTING St. Jude Children's Research Hospital, a pediatric comprehensive cancer center in the USA. PATIENTS Pediatric patients (<25 years of age) receiving conventional therapy for cancer admitted to the ICU with suspected sepsis between 2013 and 2019. RESULTS Of 207 included episodes of suspected sepsis, attributable mortality was 16 (7.7%) and all evaluated sepsis scores performed poorly (maximal AUROC of 0.73 for qSOFA at 1 and 24 h). Sensitivity analyses did not identify an alternative approach that significantly improved prediction. CONCLUSIONS Currently available sepsis scores perform poorly for prediction of attributable mortality in children with cancer who present to ICU with suspected sepsis. More research is needed to identify reliable predictors of adverse outcomes in this population.

Abstract
BACKGROUND This study aims to evaluate the clinical course of human rhinovirus/enterovirus (HRV/EV) infections in the pediatric intensive care unit. METHODS The study was conducted as a multicenter, prospective observational study from September 2022 to December 2022. Cases with positive polymerase chain reaction testing for HRV/EV of nasopharyngeal swab samples within the first 24 hours of pediatric intensive care unit admission were recorded. There were 2 groups: 1-24 months and >24 months. RESULTS A total of 75 cases (39 male) were included in the study. The median age for all cases was 21 months. The highest polymerase chain reaction positivity rates were observed in October (37.33%). Among the cases, 32 (42.67%) presented with bronchopneumonia/pneumonia, 24 (32%) presented with acute bronchiolitis/bronchitis and 7 (9.33%) presented with sepsis/septic shock. The frequency of pediatric acute respiratory distress syndrome was found to be 6.67%. In the age group of 1-24 months, mean lymphocyte and liver enzyme levels were higher, while in the age group of >24 months, mean hemoglobin and mean kidney function test levels were higher ( P ≤ 0.05). Continuous oxygen therapy was provided to 65.3% of the cases, noninvasive ventilation to 33.3%, high-flow nasal cannula-oxygen therapy to 32% and invasive mechanical ventilation to 16%. CONCLUSIONS HRV/EV infections primarily affect the respiratory system and generally exhibit a clinical course with low mortality rates (1, 1.3%). In cases with underlying chronic diseases, more severe clinical conditions such as pediatric acute respiratory distress syndrome and septic shock may occur.

Abstract
Background Recent research has demonstrated that machine learning (ML) has the potential to improve several aspects of medical application for critical illness, including sepsis. This scoping review aims to evaluate the feasibility of probabilistic graphical model (PGM) methods in pediatric sepsis application and describe the use of pediatric sepsis definition in these studies. Methods Literature searches were conducted in PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL+), and Web of Sciences from 2000-2023. Keywords included "pediatric", "neonates", "infants", "machine learning", "probabilistic graphical model", and "sepsis". Results A total of 3,244 studies were screened, and 72 were included in this scoping review. Sepsis was defined using positive microbiology cultures in 19 studies (26.4%), followed by the 2005's international pediatric sepsis consensus definition in 11 studies (15.3%), and Sepsis-3 definition in seven studies (9.7%). Other sepsis definitions included: bacterial infection, the international classification of diseases, clinicians' assessment, and antibiotic administration time. Among the most common ML approaches used were logistic regression (n=27), random forest (n=24), and Neural Network (n=18). PGMs were used in 13 studies (18.1%), including Bayesian classifiers (n=10), and the Markov Model (n=3). When applied on the same dataset, PGMs show a relatively inferior performance to other ML models in most cases. Other aspects of explainability and transparency were not examined in these studies. Conclusions Current studies suggest that the performance of probabilistic graphic models is relatively inferior to other ML methods. However, its explainability and transparency advantages make it a potentially viable method for several pediatric sepsis studies and applications.

Abstract
BACKGROUND Acute kidney injury (AKI) occurs commonly in pediatric septic shock and increases morbidity and mortality. Early identification of high-risk patients can facilitate targeted intervention to improve outcomes. We previously modified the renal angina index (RAI), a validated AKI prediction tool, to improve specificity in this population (sRAI). Here, we prospectively assess sRAI performance in a separate cohort. METHODS A secondary analysis of a prospective, multicenter, observational study of children with septic shock admitted to the pediatric intensive care unit from 1/2019 to 12/2022. The primary outcome was severe AKI (≥ KDIGO Stage 2) on Day 3 (D3 severe AKI), and we compared predictive performance of the sRAI (calculated on Day 1) to the original RAI and serum creatinine elevation above baseline (D1 SCr > Baseline +). Original renal angina fulfillment (RAI +) was defined as RAI ≥ 8; sepsis renal angina fulfillment (sRAI +) was defined as RAI ≥ 20 or RAI 8 to < 20 with platelets < 150 × 103/µL. RESULTS Among 363 patients, 79 (22%) developed D3 severe AKI. One hundred forty (39%) were sRAI + , 195 (54%) RAI + , and 253 (70%) D1 SCr > Baseline + . Compared to sRAI-, sRAI + had higher risk of D3 severe AKI (RR 8.9, 95%CI 5-16, p < 0.001), kidney replacement therapy (KRT) (RR 18, 95%CI 6.6-49, p < 0.001), and mortality (RR 2.5, 95%CI 1.2-5.5, p = 0.013). sRAI predicted D3 severe AKI with an AUROC of 0.86 (95%CI 0.82-0.90), with greater specificity (74%) than D1 SCr > Baseline (36%) and RAI + (58%). On multivariable regression, sRAI + retained associations with D3 severe AKI (aOR 4.5, 95%CI 2.0-10.2, p < 0.001) and need for KRT (aOR 5.6, 95%CI 1.5-21.5, p = 0.01). CONCLUSIONS Prediction of severe AKI in pediatric septic shock is important to improve outcomes, allocate resources, and inform enrollment in clinical trials examining potential disease-modifying therapies. The sRAI affords more accurate and specific prediction than context-free SCr elevation or the original RAI in this population.

Abstract
OBJECTIVE To determine if initial fluid resuscitation with balanced crystalloid (e.g., multiple electrolytes solution [MES]) or 0.9% saline adversely affects kidney function in children with septic shock. DESIGN Parallel-group, blinded multicenter trial. SETTING PICUs of four tertiary care centers in India from 2017 to 2020. PATIENTS Children up to 15 years of age with septic shock. METHODS Children were randomized to receive fluid boluses of either MES (PlasmaLyte A) or 0.9% saline at the time of identification of shock. All children were managed as per standard protocols and monitored until discharge/death. The primary outcome was new and/or progressive acute kidney injury (AKI), at any time within the first 7 days of fluid resuscitation. Key secondary outcomes included hyperchloremia, any adverse event (AE), at 24, 48, and 72 hours, and all-cause ICU mortality. INTERVENTIONS MES solution ( n = 351) versus 0.9% saline ( n = 357) for bolus fluid resuscitation during the first 7 days. MEASUREMENTS AND MAIN RESULTS The median age was 5 years (interquartile range, 1.3-9); 302 (43%) were girls. The relative risk (RR) for meeting the criteria for new and/or progressive AKI was 0.62 (95% CI, 0.49-0.80; p < 0.001), favoring the MES (21%) versus the saline (33%) group. The proportions of children with hyperchloremia were lower in the MES versus the saline group at 24, 48, and 72 hours. There was no difference in the ICU mortality (33% in the MES vs 34% in the saline group). There was no difference with regard to infusion-related AEs such as fever, thrombophlebitis, or fluid overload between the groups. CONCLUSIONS Among children presenting with septic shock, fluid resuscitation with MES (balanced crystalloid) as compared with 0.9% saline resulted in a significantly lower incidence of new and/or progressive AKI during the first 7 days of hospitalization.

Predictors of the onset of neonatal sepsis at the Neonatal Intensive Care Unit of a tertiary hospital in Ghana: A cross-sectional study. Health Sci Rep 2023; 6:e1673. [PMID: 37927539 PMCID: PMC10620847 DOI: 10.1002/hsr2.1673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 10/10/2023] [Accepted: 10/17/2023] [Indexed: 11/07/2023] Open
Abstract
Background and Aim Neonatal sepsis is a systemic inflammatory response to infection during the first 4 weeks of an infant's life. It is a significant cause of neonatal morbidity and mortality in low- and middle-income countries. This study aimed to determine the predictors of the onset of sepsis at the Neonatal Intensive Care Unit of the Tamale Teaching Hospital, Ghana. Methods A cross-sectional study was conducted among 275 mothers and their singleton neonates diagnosed clinically with sepsis. A univariate and multivariate logistic regression analysis adjusted for maternal occupational status was performed to determine the maternal and neonatal predictors of early-onset (EOS) and late-onset sepsis (LOS), respectively. Results Single motherhood (AOR = 1.882, 95% CI = 0.926-3.822, p = .08) and home delivery (AOR = 3.667, 95% CI = 0.584-23.026, p = .17) were predictors of EOS, with single motherhood being the predictor for LOS (AOR = 2.906, 95% CI = 0.715-11.805, p = .14) in a univariate analysis. When maternal occupation was adjusted for in a multivariate analysis, single mother (AOR = 2.167, 95% CI = 1.010-4.648, p = .04) was the main predictor of EOS, with low neonatal birth weight being the main predictor of LOS (AOR = 0.193, 95% CI = 0.038-0.971, p = .04). Conclusion Maternal marital status is a significant predictor of both EOS and LOS, with predictors of EOS being lower gestational age and low birth weight, while for LOS, low birth weight is the main predictor. Findings from this study can serve as a commencement point for developing predictive models for the onset of sepsis in neonates in the study facility.

Abstract
Refractory septic shock is associated with a high risk of death. Circulatory support in the form of veno-arterial extracorporeal membrane oxygenation (VA ECMO) may function as a bridge to recovery, allowing for the treatment of the source of the sepsis. Whilst VA ECMO has been accepted as the means of hemodynamic support for children, in adults, single center observational studies show survival rates of only 70-90% for hypodynamic septic shock. The use of VA ECMO for circulatory support in hyperdynamic septic shock with preserved cardiac output or when applied late during cardio-pulmonary resuscitation is not recommended. With unresolving septic shock and a loss of ventriculo-arterial coupling, stress cardiomyopathy often develops. If the cardiac index (CI) approaches subnormal levels (CI < 2.5 L/min m-2) that do not match low systemic vascular resistance with a resulting loss of vital systemic perfusion pressure, VA ECMO support should be considered. A further decrease to the level of cardiogenic shock (CI < 1.8 L/min m-2) should be regarded as an indication for VA ECMO insertion. For patients who maintain a normal-to-high CI as part of their refractory vasoparalysis, VA ECMO support is justified in children and possibly in patients with a low body mass index. Extracorporeal support for septic shock should be limited to high-volume ECMO centers.

Abstract
BACKGROUND Sepsis is a clinical syndrome associated with a systemic reaction to infection that is seen as a bacteremia with systemic symptoms. Sepsis is one of the most important problems in children and is associated with many deaths, so recognizing this disease and it's causing factors and identifying the predisposing factors for it is of great importance. Globally, the prevalence and occurrences of sepsis and septic shock are increasing, while the incidence of deaths from them has decreased with the improvement of diagnostic and treatment facilities. According to a 2015 World Health Organization report, approximately 5.9 million children under 5 years old have lost their lives due to sepsis worldwide, the majority of which have occurred in developing countries. METHODS This study was conducted in the pediatric department of Maiwand Teaching Hospital (MTH) in 2020 as a descriptive cross-sectional study. All children who were admitted to the pediatric department of Maiwand Teaching Hospital during 2020 were included in the research. Among them, the prevalence of sepsis in children with respect to age and sex was studied. The study included children over the age of 28 days who were admitted to the Maiwand Teaching Hospital pediatrics department in 2020. However, in this study, patients have been categorized into five categories according to age: less than two months, two months to one year, one to three years, three to five years old, and older than five years old. RESULTS This study was conducted in the pediatric department of Maiwand Teaching Hospital in 2020 as a descriptive cross-sectional study, and it was found that the prevalence of sepsis in children who were admitted to the pediatric department at this year was 50.5%, including the highest prevalence in males (65.75%) and at the age of two months to one year (37.9%). In this study, it was found that the prevalence of sepsis was higher (88.46%) among urban children than children who were living in villages (11.53%). In this study, the mortality rate was 2.44% for patients admitted to Maiwand Teaching Hospital. CONCLUSIONS In this study, it was found that the prevalence of sepsis was 50.5% in children admitted to the pediatrics department of Maiwand Teaching Hospital, of whom 67.75% were boys, 37.94% were aged two months to three years old, and it was more prevalent (88.46%) among children living in cities. The mortality rate was 2.44%.
