Multiple Organ Dysfunction Syndrome in Malawian Children with Cerebral Malaria.

More than 1,000 children under 5 years of age die every day from malaria. Cerebral malaria (CM) is the most severe and deadly manifestation of the disease. The occurrence of multiple organ dysfunction syndrome (MODS) has been associated with increased mortality in adult patients with CM. However, little is known about the frequency and severity of MODS in children with CM. This was a retrospective study of 199 pediatric patients with CM admitted to a referral hospital in Blantyre, Malawi, between January 2019 and May 2023. Data were abstracted from charts to calculate scores using four established scoring systems: Pediatric Logistic Organ Dysfunction-2 (PELOD-2), Pediatric Sequential Organ Failure Assessment (pSOFA), Signs of Inflammation in Children that Can Kill (SICK), and Lambaréné Organ Dysfunction Score (LODS). Mortality was 16% (n = 32). All four scoring systems were predictive of mortality, but the PELOD-2 and pSOFA scores outperformed the others with area under the curve values of 0.75 and 0.67, respectively. Multiple organ dysfunction syndrome was diagnosed in 182 patients (91%) using the PELOD-2 score, 172 patients (86%) using the pSOFA score, 99 patients (50%) using the SICK score, and 30 patients (15%) using the LODS. The PELOD-2 and pSOFA identify MODS in children with CM but require laboratory-based testing that is often unavailable in malaria-endemic areas. Furthermore, these scoring systems may identify primary malarial disease pathology rather than true organ dysfunction. Simplified scoring systems designed to recognize and quantify MODS in this patient population may provide opportunities for improved resource allocation and timely, organ-specific treatment.

Postoperative Organ Dysfunction Risk Stratification Using Extracellular Vesicle-Derived circRNAs in Pediatric Congenital Heart Surgery.

Breakthroughs in surgical and medical techniques have significantly improved outcomes for children with congenital heart disease (CHD), but research continues to address the ongoing challenge of organ dysfunction after surgery, particularly in neonates and infants. Our study explored circular RNAs (circRNAs) within plasma-derived extracellular vesicles (EVs) in neonates and infants undergoing CHD surgery. Post-surgery EV circRNAs showed dramatic expression changes between organ dysfunction (OD) and control groups. Tissue injury-related pathways were consistent across pre- and post-surgery in OD. The top two significant predicted tissue sources of these circRNAs originated from the respiratory system, aligning with the fact that all patients in the OD arm experienced respiratory dysfunction. Five of these circRNAs, namely circ-CELSR1, circ-PLXNA1, circ-OBSL1, circ-DAB2IP, and circ-KANK1, significantly correlated with PELOD (Pediatric Logistic Organ Dysfunction) score and demonstrated high performance (AUC = 0.95), supporting the potential of circRNAs as prognostic markers. These findings pave the way for EV circRNAs as promising tools for managing post-surgical organ dysfunction and potentially guiding therapeutic strategies in children with CHD.

Characteristics and outcomes of children ≤ 10 kg receiving continuous kidney replacement therapy: a WE-ROCK study.

Continuous kidney replacement therapy (CKRT) is often used for acute kidney injury (AKI) or fluid overload (FO) in children ≤ 10kg. Intensive care unit (ICU) mortality in children ≤ 10kg reported by the prospective pediatric CRRT (ppCRRT, 2001-2003) registry was 57%. We aimed to evaluate characteristics associated with ICU mortality using a contemporary registry. The Worldwide Exploration of Renal Replacement Outcomes Collaborative in Kidney Disease (WE-ROCK) registry is a retrospective, multinational, observational study of children and young adults aged 0-25years receiving CKRT (2015-2021) for AKI or FO. This analysis included patients ≤ 10kg at hospital admission. ICU mortality and major adverse kidney events at 90days (MAKE-90) defined as death, persistent kidney dysfunction, or dialysis within 90days, respectively. A total of 210 patients were included (median age 0.53years (IQR, 0.1, 0.9)). ICU mortality was 46.5%. MAKE-90 occurred in 150/207 (72%). CKRT was initiated at a median 3days (IQR 1, 9) after ICU admission and lasted a median 6days (IQR 3, 16). On multivariable analysis, pediatric logistic organ dysfunction score (PELOD-2) at CKRT initiation was associated with increased odds of ICU mortality (aOR 2.64, 95% CI 1.68-4.16), and increased odds of MAKE-90 (aOR 2.2, 95% CI 1.31-3.69). Absence of comorbidity was associated with lower MAKE-90 (aOR 0.29, 95%CI 0.13-0.65). We report on a contemporary cohort of children ≤ 10kg treated with CKRT for acute kidney injury and/or fluid overload. ICU mortality is decreased compared to ppCRRT. The extended risk of death and morbidity at 90days highlights the importance of close follow-up.

The Association between Dynamic Pressure Gradient and Mortality in Patients with Acute Respiratory Distress Syndrome in a Pediatric Intensive Care Unit: A Single-Center Retrospective Cohort

Abstract Background: Lung-protective ventilation strategies, one of which is to limit peak inspiratory pressure (PIP), are recommended in the management of acute respiratory distress syndrome (ARDS). The purpose of this study was to determine whether dynamic pressure gradient, defined as the difference between PIP and positive end-expiratory pressure (PEEP), is associated with pediatric ARDS mortality in the pediatric intensive care unit (PICU). Materials and Methods: This was a retrospective, single-center cohort study with consecutive sampling. Children aged 1 month to 18 years with ARDS who were admitted to PICU and used invasive mechanical ventilator between January and December 2023 were included. Patient’s demographic data, pediatric logistic organ dysfunction 2 (PELOD-2) score, oxygenation index (OI), oxygen saturation index (OSI), PEEP, and dynamic pressure gradient were collected from the patient’s medical record. The outcome is mortality, which is measured upon discharge. Results: The subjects’ median age was 6 months, predominantly male (64.06%). The etiology of ARDS was pneumonia (90.63%) and sepsis (9.37%). Bivariate analysis showed that dynamic pressure gradient (OR = 4.77, 95% CI=1.47–15.5, P = 0.003), PEEP (OR = 3.21, 95% CI = 1.07–9.52, P = 0.033), and PELOD-2 score at 24–72 h (OR = 3.68, 95% CI = 1.146–11.83, P = 0.024) had a significant association with mortality of ARDS patients at PICU. The results of multivariate analysis showed that dynamic pressure gradient had a significant relationship with the mortality of ARDS patients at PICU (OR = 5.22, 95% CI = 1.47–18.56, P = 0.015). Conclusion: Dynamic pressure gradient was associated with mortality in pediatric patients with ARDS who were treated in PICU.

Comparison Between Mortality Scoring Systems in Pediatric Intensive Care Unit Reliability and Effectiveness

Purpose: In pediatric intensive care unit (PICU), high mortality risk is a significant issue. Risk adjustment tools are in place for early estimation of mortality risk. Pediatric Risk of Mortality(PRISM), Pediatric Index of Mortality(PIM), Pediatric Logistic Organ Dysfunction(PELOD) and Pediatric Sequential Organ Failure Assessment(PSOFA) are commonly used. The aim of this study was to evaluate the predictive performance of mortality using PRISM III, PIM3, PELOD-2, and PSOFA. Materials and Methods: This retrospective single-center study analysed patients aged between 1month-18years who were treated in PICU for various diseases between April and December2021. Their electronic records were retrospectively examined for demographic characteristics, medical and clinical expectations, and morbidity/mortality. Results: The study included 300 patients with a hospitalization period of 56.73±105.95 days. At the end of the study, 56(18.7%) patients had died.All scoring systems and mortality correlations were statistically significant(p

The Association of PELOD-2 Score and Nutritional Status of Children Treated in the Pediatric Intensive Care Unit at Prof. Dr. I.G.N.G. Ngoerah Hospital Denpasar, 2020-2022

Background: The Pediatric Logistic Organ Dysfunction (PELOD-2) is used to measure the severity of vital organ dysfunction due to disease or other medical conditions in pediatric patients admitted to the Pediatric Intensive Care Unit (PICU). Nutritional status is a crucial factor affecting the body's ability to fight disease and the risk of complications. The aim was to evaluate the association between PELOD-2 scores and nutritional status in children treated in the PICU of Prof. Dr. I.G.N.G. Ngoerah Hospital Denpasar. Methods: This study employed a retrospective cross-sectional design using medical record data of children aged 1 month to 18 years treated in the PICU of Prof. Dr. I.G.N.G. Ngoerah Hospital Denpasar from January 2020 to December 2022. Data were collected from 428 subjects meeting the inclusion and exclusion criteria. Data analysis was performed using Chi-Square tests and logistic regression. Results: The study results indicated that PELOD-2 scores were significantly associated with poor nutritional status (OR: 1.71; 95% CI: 1.107–2.73), ventilator use (OR: 5.4; 95% CI: 3.336–8.913), and gender, with males being at higher risk (OR: 1.66; 95% CI: 1.042–2.654). Older age was found to be a protective factor against high PELOD-2 scores (ExpB: 0.996; 95% CI: 0.993–1.00). Conclusion: PELOD-2 scores are significantly associated with poor nutritional status, age, ventilator use, and gender in children treated in the PICU.

Pediatric Acute Respiratory Distress Syndrome Severity and Health-Related Quality of Life Outcomes: Single-Center Retrospective Cohort, 2011-2017.

To determine factors associated with health-related quality of life (HRQL) decline among pediatric acute respiratory distress syndrome (PARDS) survivors. Retrospective cohort study. Academic children's hospital. Three hundred fifteen children 1 month to 18 years old with an unplanned PICU admission from December 2011 to February 2017 enrolled in the hospital's Outcomes Assessment Program. None. Pre-admission baseline and median 6-week post-discharge HRQL were assessed using the Pediatric Quality of Life Inventory or the Functional Status II-R. Patients meeting retrospectively applied Second Pediatric Acute Lung Injury Consensus Conference criteria for PARDS were identified, and PARDS severity was classified using binary (mild/moderate, severe) and trichotomous (mild, moderate, severe) categorization for noninvasive ventilation and invasive mechanical ventilation (IMV). PARDS occurred in 41 of 315 children (13.0%). Clinically important HRQL decline (≥ 4.5 points) occurred in 17 of 41 patients (41.5%) with PARDS and 64 of 274 without PARDS (23.4%). On multivariable generalized linear regression adjusted for age, baseline Pediatric Overall Performance Category, maximum nonrespiratory Pediatric Logistic Organ Dysfunction score, diagnosis, length of stay, and time to follow-up, PARDS was associated with HRQL decline (adjusted relative risk [aRR], 1.70; 95% CI, 1.03-2.77). Four-hour and maximum PARDS severity were the only factors associated with HRQL decline. HRQL decline occurred in five of 18 patients with mild PARDS at 4 hours, five of 13 with moderate PARDS (aRR 2.35 vs. no PARDS [95% CI, 1.01-5.50]), and seven of ten with severe PARDS (aRR 2.56 vs. no PARDS [95% CI, 1.45-4.53]). The area under the receiver operating characteristic curve for discrimination of HRQL decline for IMV patients was 0.79 (95% CI, 0.66-0.91) for binary and 0.80 (95% CI, 0.69-0.93) for trichotomous severity categorization. HRQL decline is common among children surviving PARDS, and risk of decline is associated with PARDS severity. HRQL decline from baseline may be an efficient and clinically meaningful endpoint to incorporate into PARDS clinical trials.

Medical Complexity, Language Use, and Outcomes in the Pediatric ICU.

To determine whether use of a language other than English (LOE) would be associated with medical complexity, and whether medical complexity and LOE together would be associated with worse clinical outcomes. The primary outcome of this single-site retrospective cohort study of PICU encounters from September 1, 2017, through August 31, 2022 was an association between LOE and medical complexity. Univariable and multivariable analyses were performed between demographic factors and medical complexity, both for unique patients and for all encounters. We investigated outcomes of initial illness severity (using Pediatric Logistic Organ Dysfunction-2), length of stay (LOS), days without mechanical ventilation or organ dysfunction using a mixed effects regression model, controlling for age, sex, race and ethnicity, and insurance status. There were 6802 patients and 10 011 encounters. In multivariable analysis for all encounters, Spanish use (adjusted odds ratio [aOR], 1.29; 95% confidence interval [CI], 1.11-1.49) and language other than English or Spanish (LOES) (aOR, 1.36; 95% CI, 1.02-1.80) were associated with medical complexity. Among unique patients, there remained an association between use of Spanish and medical complexity in multivariable analysis (aOR, 1.26; 95% CI, 1.05-1.52) but not between LOES and medical complexity (aOR, 1.30; 95% CI, 0.92-1.83). Children with medical complexity (CMC) who used an LOES had fewer organ dysfunction-free days (P = .003), PICU LOS was 1.53 times longer (P = .01), and hospital LOS was 1.45 times longer (P = .01) compared with CMC who used English. Use of an LOE was independently associated with medical complexity. CMC who used an LOES had a longer LOS.

Clinical characteristics of children on prolonged mechanical ventilation due to different primary diseases

To investigate the differences in clinical characteristics among children on prolonged mechanical ventilation (PMV) due to different primary diseases. A retrospective analysis was performed on the clinical data of 59 pediatric patients requiring PMV from July 2017 to September 2022. According to the primary disease, they were divided into respiratory disease (RD) group, central nervous system (CNS) group, neuromuscular disease (NMD) group, and other disease group. The four groups were compared in terms of general information, treatment, and outcome. There were significant differences among the four groups in age, body weight, Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score, Pediatric Risk of Mortality III (PRISM Ⅲ) score, analgesic and sedative treatment, nutrition supply, rehabilitation treatment, tracheotomy, successful ventilator weaning, and outcomes (P<0.05). Compared with the RD group, the CNS group and the other disease group had a significantly higher age and a significantly higher proportion of children receiving rehabilitation treatment, and the CNS group had a significantly higher proportion of children receiving tracheotomy (P<0.008). Compared with the other disease group, the CNS group and the NMD group had significantly lower PELOD-2 and PRISM III scores, and the CNS group had a significantly higher proportion of children with successful ventilator weaning and a significantly higher proportion of children who were improved and discharged (P<0.008). There are differences in clinical characteristics among children receiving PMV due to different etiologies. Most children in the RD group have a younger age, and children in the CNS group have a relatively good prognosis.

Patterns of Multiple Organ Dysfunction and Renal Recovery in Critically Ill Children and Young Adults Receiving Continuous Renal Replacement Therapy.

Acute kidney injury requiring dialysis (AKI-D) commonly occurs in the setting of multiple organ dysfunction syndrome (MODS). Continuous renal replacement therapy (CRRT) is the modality of choice for AKI-D. Mid-term outcomes of pediatric AKI-D supported with CRRT are unknown. We aimed to describe the pattern and impact of organ dysfunction on renal outcomes in critically ill children and young adults with AKI-D. Retrospective cohort. Two large quarternary care pediatric hospitals. Patients 26 y old or younger who received CRRT from 2014 to 2020, excluding patients with chronic kidney disease. None. Organ dysfunction was assessed using the Pediatric Logistic Organ Dysfunction-2 (PELOD-2) score. MODS was defined as greater than or equal to two organ dysfunctions. The primary outcome was major adverse kidney events at 30 days (MAKE30) (decrease in estimated glomerular filtration rate greater than or equal to 25% from baseline, need for renal replacement therapy, and death). Three hundred seventy-three patients, 50% female, with a median age of 84 mo (interquartile range [IQR] 16-172) were analyzed. PELOD-2 increased from 6 (IQR 3-9) to 9 (IQR 7-12) between ICU admission and CRRT initiation. Ninety-seven percent of patients developed MODS at CRRT start and 266 patients (71%) had MAKE30. Acute kidney injury (adjusted odds ratio [aOR] 3.55 [IQR 2.13-5.90]), neurologic (aOR 2.07 [IQR 1.15-3.74]), hematologic/oncologic dysfunction (aOR 2.27 [IQR 1.32-3.91]) at CRRT start, and progressive MODS (aOR 1.11 [IQR 1.03-1.19]) were independently associated with MAKE30. Ninety percent of critically ill children and young adults with AKI-D develop MODS by the start of CRRT. Lack of renal recovery is associated with specific extrarenal organ dysfunction and progressive multiple organ dysfunction. Currently available extrarenal organ support strategies, such as therapeutic plasma exchange lung-protective ventilation, and other modifiable risk factors, should be incorporated into clinical trial design when investigating renal recovery.

Paediatric sequential organ failure assessment score (p-SOFA) as an outcome predictor in critically ill children admitted to a paediatric intensive care unit in a tertiary care hospital in central India.

Background Pediatric intensive care remains a critical and challenging field, where early recognition of organ dysfunction and timely intervention are essential for improved patient outcomes. The Pediatric Sequential Organ Failure Assessment (P-SOFA) score is a tool designed to assess organ dysfunction in critically ill children. This prospective observational study aims to evaluate the effectiveness of the P-SOFA score in predicting morbidity and mortality in pediatric patients admitted to the Pediatric Intensive Care Unit (PICU). Methods Over two years, we will enrol pediatric patients aged one month to 17 years in the PICU at Jawaharlal Nehru Medical College and AVBRH, Sawangi, Wardha, Central India. Data will be collected on demographic characteristics, clinical assessments, laboratory investigations, SOFA score calculations at admission and 48 hours later, treatments received, and outcomes. Inclusion criteria encompass patients with PICU stays exceeding 24 hours, while exclusion criteria include consent refusal, planned procedures for PICU admission, and PICU stays of less than 24 hours. Expected Results We anticipate that the P-SOFA score will be a valuable predictor of morbidity and mortality in critically ill pediatric patients. The study will also investigate the potential of ΔSOFA (change in SOFA scores) as an outcome indicator and compare the P-SOFA score with the Pediatric Logistic Organ Dysfunction Score 2 (PELOD2) for mortality prediction.

Factors associated with successful liberation from continuous renal replacement therapy in children and young adults: analysis of the worldwide exploration of renal replacement outcomes collaborative in Kidney Disease Registry.

Continuous renal replacement therapy (CRRT) is used for supportive management of acute kidney injury (AKI) and disorders of fluid balance (FB). Little is known about the predictors of successful liberation in children and young adults. We aimed to identify the factors associated with successful CRRT liberation. The Worldwide Exploration of Renal Replacement Outcomes Collaborative in Kidney Disease study is an international multicenter retrospective study (32 centers, 7 nations) conducted from 2015 to 2021 in children and young adults (aged 0-25years) treated with CRRT for AKI or FB disorders. Patients with previous dialysis dependence, tandem extracorporeal membrane oxygenation use, died within the first 72h of CRRT initiation, and those who never had liberation attempted were excluded. Patients were categorized based on first liberation attempt: reinstituted (resumption of any dialysis within 72h) vs. success (no receipt of dialysis for ≥ 72h). Multivariable logistic regression was used to identify factors associated with successful CRRT liberation. A total of 622 patients were included: 287 (46%) had CRRT reinstituted and 335 (54%) were successfully liberated. After adjusting for sepsis at admission and illness severity parameters, several factors were associated with successful liberation, including higher VIS (vasoactive-inotropic score) at CRRT initiation (odds ratio [OR] 1.35 [1.12-1.63]), higher PELOD-2 (pediatric logistic organ dysfunction-2) score at CRRT initiation (OR 1.71 [1.24-2.35]), higher urine output prior to CRRT initiation (OR 1.15 [1.001-1.32]), and shorter CRRT duration (OR 0.19 [0.12-0.28]). Inability to liberate from CRRT was common in this multinational retrospective study. Modifiable and non-modifiable factors were associated with successful liberation. These results may inform the design of future clinical trials to optimize likelihood of CRRT liberation success.

Mortality in Patients with Leukemia and Lymphoma Urgently Admitted to the PICU: Secondary Analysis of Data from a Cluster Randomized Controlled Trial

AbstractObjectives were to describe the severity of illness in patients with leukemia or lymphoma urgently admitted to pediatric intensive care and explores the risk factors for mortality. A secondary analysis was performed of prospectively collected data from a cluster-randomized controlled trial in 21 children's hospitals from 2011 to 2015. Eligible patients were urgently admitted to intensive care and had a diagnosis of leukemia or lymphoma. Associations with intensive care mortality (primary outcome) were determined with multivariable generalized estimating equation with a logit link, accounting for clustering by site. Associations with time to intensive care mortality (secondary outcome) were determined with multivariable proportional hazards models. A total of 109 patients were included, age 115 (interquartile range [IQR] 42, 168) months and intensive care length of stay was 3 (IQR 2, 6) days. During the first hour in intensive care 36 (33%) were ventilated, and during intensive care 45 (41.3%) had at least 1 technology day. Day 1 Pediatric Logistic Organ Dysfunction (PELOD) score was ≥ 20 in 37 (33.9%), Pediatric Index of Mortality 2 mortality risk was &gt; 10% in 35 (32.1%), and Children's Resuscitation Intensity Scale (RISC) was ≥ 3 (late admission to intensive care) in 32 (31.7%). Intensive care mortality was 20/109 (18.3%); with intensive care stay ≥ 20 days mortality was 51%. Previous urgent pediatric intensive care unit (PICU) admission, mechanical ventilation, and day 1 PELOD score were associated with higher PICU mortality. Mechanical ventilation, day 1 PELOD score, and late admission to the PICU (RISC ≥ 2) were associated with time to death. Patients with leukemia and lymphoma urgently admitted to intensive care had mortality of 18.3%, an improvement from historical cohorts. Risk factors were not accurate enough to make individual patient care decisions.

High-dose intravenous immunoglobulin versus albumin 4% in paediatric toxic shock syndrome: a randomised controlled feasibility study

PurposeToxic shock syndrome (TSS) is a rare disease responsible for significant morbidity and mortality. Intravenous immunoglobulin (IG) therapy in paediatric TSS could improve shock and organ failure, but more consistent...

Iron Deficiency in Anemic Children Surviving Critical Illness: Post Hoc Analysis of a Single-Center Prospective Cohort in Canada, 2019-2022.

Many children leave the PICU with anemia. The mechanisms of post-PICU anemia are poorly investigated, and treatment of anemia, other than blood, is rarely started during PICU. We aimed to characterize the contributions of iron depletion (ID) and/or inflammation in the development of post-PICU anemia and to explore the utility of hepcidin (a novel iron marker) at detecting ID during inflammation. Post hoc analysis of a single-center prospective study (November 2019 to September 2022). PICU, quaternary center, Canada. Children admitted to PICU with greater than or equal to 48 hours of invasive or greater than or equal to 96 hours of noninvasive ventilation. We excluded patients with preexisting conditions causing anemia or those admitted after cardiac surgery. None. Hematological and iron profiles were performed at PICU discharge on 56 participants of which 37 (37/56) were diagnosed with anemia. Thirty-three children (33/56; 59%) were younger than 2 years. Median Pediatric Logistic Organ Dysfunction score was 11 (interquartile range, 6-16). Twenty-four of the 37 anemic patients had repeat bloodwork 2 months post-PICU. Of those, four (4/24; 16%) remained anemic. Hematologic profiles were categorized as: anemia of inflammation (AI), iron deficiency anemia (IDA), IDA with inflammation, and ID (low iron stores without anemia). Seven (7/47; 15%) had AI at discharge, and one had persistent AI post-PICU. Three patients (3/47; 6%) had IDA at discharge; of which one was lost to follow-up and the other two were no longer anemic but had ID post-PICU. Eleven additional patients developed ID post-PICU. In the exploratory analysis, we identified a diagnostic cutoff value for ID during inflammation from the receiver operating characteristic curve for hepcidin of 31.9 pg/mL. This cutoff would increase the detection of ID at discharge from 6% to 34%. The burden of ID in children post-PICU is high and better management strategies are required. Hepcidin may increase the diagnostic yield of ID in patients with inflammation.

Association of an In-Hospital Desirability of Outcomes Ranking Scale With Postdischarge Health-Related Quality of Life: A Secondary Analysis of the Life After Pediatric Sepsis Evaluation.

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. Secondary analysis of the Life After Pediatric Sepsis Evaluation prospective study. Twelve U.S. PICUs, 2013-2017. Children (1 mo-18 yr) with septic shock. None. 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]). 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.

Comparative assessment of the prognostic ability of paediatric Sequential Organ Failure Assessment (pSOFA), paediatric logistic organ dysfunction 2 (PELOD 2) and Vasoactive-Inotropic Score (VIS) in children with septic shock: a retrospective observational study

INTRODUCTION: Septic shock is the most severe stage of sepsis in children accompanied by a highest mortality. OBJECTIVE: The aim of the work is to compare an informative significance of pSOFA, PELOD 2 scales and VIS as predictors of mortality in children with septic shock. MATERIALS AND METHODS: The design of the study is retrospective, observational, single-center trial. The study was performed in the Children's Regional Clinical Hospital of Krasnodar. The inclusion criteria were children with septic shock from 9 months to 17 years old. The endpoint of trial was 28-day mortality. Demographic and clinical characteristic were presented with median and average values, also interquartile intervals were counted. Mann-Whitney U-test was used for comparison data received. The discriminatory power, sensitivity and specificity were defined with receiver operating characteristic (ROC) analysis and determination of area under ROC curve (AUC). RESULTS: No one of this trial’s score provides a prediction of children’s survival with sepsis and shock during first 24 hour PICU stay. PELOD 2 and pSOFA scores allow to estimate a prediction from day 3 from PICU stay. Furthermore PELOD 2 score shows a higher informative significance. The VIS has an ability to predict survival on day 5 from admission. CONCLUSIONS: Only the PELOD 2 score has a good discriminatory power regarding the prognosis of survival in children with septic shock after 48 hours of intensive care. The VIS scale allow to assess a severity of cardiovascular dysfunction in children with refractory septic shock with threshold critical value more than 21 points.

Incidence, outcome, and prognostic factors of prolonged mechanical ventilation among children in Chinese mainland: a multi-center survey.

To evaluate the incidence, outcome, and prognostic factors of prolonged mechanical ventilation (PMV) in children in Mainland China. A prospective study was conducted in 11 pediatric intensive care units (PICUs) from May 1, 2021, to April 30, 2022. All pediatric patients on mechanical ventilation meeting the criteria for PMV were included in the study. Out of 5,292 patients receiving mechanical ventilation, 278 children met the criteria for PMV (5.3%). After excluding case with incomplete data or lost to follow-up, the study included 250 patients. Among them, 115 were successfully weaned from mechanical ventilation, 90 died, and 45 were still on mechanical ventilation. The 6-month survival rate was 64%. The primary associated conditions of PMV were lower airway diseases (36%), central nervous system diseases (32%), and neuromuscular diseases (14%). The stepwise multiple logistic regression analysis indicated that the utilization of vasoactive agents and an elevated pediatric logistic organ dysfunction-2 (PELOD-2) score on the day of PMV diagnosis were significantly associated with an increased of PMV death. Specifically, the odds ratio (OR) for vasoactive agent use was 2.86; (95% CI: 0.15-0.84; P = 0.018), and for the PELOD-2 score, it was 1.37; 95% CI: 1.17-1.61; P < .001). Conversely, early rehabilitation intervention was negatively associated with the risk of PMV death (OR = 0.45; 95% CI: 0.22-0.93; P = .032). Furthermore, the tracheotomy timing emerged as an independent predictor of failure to wean from PMV, with an OR of 1.08, (95% CI: 1.01-1.16; P = .030). The study revealed a 5.3% incidence of PMV in children requiring mechanical ventilation in China. The use of vasoactive agents and a higher PELOD-2 score at PMV diagnosis were significantly associated with an increased risk of PMV death, whereas early rehabilitation intervention was identified as crucial for improving patient outcomes. The timing of tracheostomy was identified as a high-risk factor for failure to wean from mechanical ventilation.

Comparison of bedside risk assessment scores to predict the outcome of patients with acute febrile illness admitted to pediatric intensive care unit: A single-center prospective observational study

Abstract Background: Acute febrile illness (AFI) is the most common presentation in the pediatric emergency room, and bedside risk assessment scores are very useful to identify those at risk. This study aimed to evaluate the predictive validity of quick Sequential Organ Failure Assessment (qSOFA), quick Pediatric Logistic Organ Dysfunction-2 (qPELOD-2), Liverpool qSOFA (LqSOFA), and Pediatric Early Warning Score (PEWS) to predict the outcome of patients with AFI admitted to the pediatric intensive care unit (PICU). Subjects and Methods: This prospective observational study included children under the age of 18 years admitted to PICU. A thorough history and examination was performed in the ER, and the qSOFA, the qPELOD-2, the LqSOFA, and the PEWS scores were calculated. The primary outcome was inhospital mortality. The capacity of the scores to predict outcome was evaluated for calibration (using Hosmer–Lemeshow adaptation of the Chi-square test) and discrimination (using receiver operating characteristic [ROC] curve). The scores were compared for any significant difference using z-statistics. Results: The study included 239 patients with the most common diagnosis of dengue fever. The overall mortality rate in the study was 8.4%. On the calibration of the models, all the scores showed a good fit to predict mortality. On discrimination by ROC curve, the LqSOFA score and PEWS had the best area under the curve for ROC curve (AUC-ROC) (0.913), followed by the qSOFA score (0.859). On comparing the AUC-ROC curve, no statistically significant difference was found between the scoring systems to predict mortality. Conclusions: Bedside risk stratification scores are a simple and convenient tool to identify patients at risk for mortality and assess prognosis. No single assessment tool was found superior to others.

Pediatric Critical Care Illness Severity Toolkit: Stata Commands for Calculation of Pediatric Index of Mortality and Pediatric Logistic Organ Dysfunction Scores.

Illness severity scoring tools, such as PRISM III/IV, PIM-3, and PELOD-2, are widely used in pediatric critical care research. However, their application is hindered by complex calculation processes, privacy concerns with third-party online calculators, and challenges in accurate implementation within statistical packages. We have developed a comprehensive, open-source toolkit for implementing the PIM-3, Simplified PIM-3, and PELOD-2 scores. The toolkit includes the pim3 and pelod2 commands and is compatible with Stata versions 12 and above. It features robust data validation, error messaging, a graphical interface, and support for SI and Imperial units. The toolkit's accuracy was validated through unit testing and synthetic data, comparing results with existing implementations. In performance tests, the toolkit exhibited a median processing time of 21.82 seconds for PELOD-2, 14.06 seconds for PIM-3, and 9.74 seconds for Simplified PIM-3, when applied to datasets of 10,000,000 records. It consistently achieved 100% accuracy in both synthetic data tests and manual spot checks. The toolkit decreases processing time and improves accuracy in calculating pediatric critical care severity scores such as PELOD-2, PIM-3, and Simplified PIM-3. Its application in large datasets and validation highlights its utility as a tool for streamlining pediatric critical care research.
