Abstract
OBJECTIVES To use the ventricular pressure-volume relationship and time-varying elastance model to provide a foundation for understanding cardiovascular physiology and pathophysiology, interpreting advanced hemodynamic monitoring, and for illustrating the physiologic basis and hemodynamic effects of therapeutic interventions. We will build on this foundation by using a cardiovascular simulator to illustrate the application of these principles in the care of patients with severe sepsis, cardiogenic shock, and acute mechanical circulatory support. DATA SOURCES Publications relevant to the discussion of the time-varying elastance model, cardiogenic shock, and sepsis were retrieved from MEDLINE. Supporting evidence was also retrieved from MEDLINE when indicated. STUDY SELECTION, DATA EXTRACTION, AND SYNTHESIS Data from relevant publications were reviewed and applied as indicated. CONCLUSIONS The ventricular pressure-volume relationship and time-varying elastance model provide a foundation for understanding cardiovascular physiology and pathophysiology. We have built on this foundation by using a cardiovascular simulator to illustrate the application of these important principles and have demonstrated how complex pathophysiologic abnormalities alter clinical parameters used by the clinician at the bedside.

Abstract
The field of pediatric neurocritical care (PNCC) has expanded and evolved over the last three decades. As mortality from pediatric critical care illness has declined, morbidity from neurodevelopmental disorders has expanded. PNCC clinicians have adopted a multidisciplinary approach to rapidly identify neurological injury, implement neuroprotective therapies, minimize secondary neurological insults, and establish transitions of care, all with the goal of improving neurocognitive outcomes for their patients. Although there are many aspects of PNCC and adult neurocritical care (NCC) medicine that are similar, elemental difference between adult and pediatric medicine has contributed to a divergent evolution of the respective fields. The low incidence of pediatric critical care illness, the heterogeneity of neurological insults, and the limited availability of resources all shape the need for a PNCC clinical care model that is distinct from the established paradigm adopted by the adult neurocritical care community at large. Considerations of neurodevelopment are fundamental in pediatrics. When neurological injury occurs in a child, the neurodevelopmental stage at the time of insult alters the impact of the neurological disease. Developmental variables contribute to a range of outcomes for seemingly similar injuries. Despite the relative infancy of the field of PNCC, early reports have shown that implementation of a specialized PNCC service elevates the quality and safety of care, promotes education and communication, and improves outcomes for children with acute neurological injuries. The multidisciplinary approach of PNCC clinicians and researchers also promotes a culture that emphasizes the importance of quality improvement and education initiatives, as well as development of and adherence to evidence-based guidelines and family-focused care models.

Abstract
BACKGROUND Advancements in cancer treatment have resulted in longer survival but often at the expense of new therapy-associated morbidities. The aim of this study is to evaluate functional outcomes of hemato-oncology patients at PICU discharge, and to identify associated risk factors. METHODS A single-center retrospective observational study. All children (< 19 years) with a hemato-oncology diagnosis admitted to the Hong Kong Children's Hospital PICU over a 2-year period were included. Functional status upon admission and discharge were compared. Univariable and multi-variable analyses were employed to identify risk factors associated with new morbidities. RESULTS Out of 288 PICU admissions, there were 277 live discharges (mortality 4%), of which 52 (18.8%) developed new morbidities. Emergency admission, severity of illness at admission, organ dysfunction and support were associated with new morbidities (OR 1.08-11.96; p < 0.05). Adjusting for confounding factors, higher Pediatric Logistic Organ Dysfunction 2 score at admission was significantly associated with development of new morbidities (OR 1.34; 95% CI 1.18-1.54; p < 0.001). CONCLUSION Critically ill children with hemato-oncological diseases had a higher rate of developing new morbidities (18.8%) compared with the general PICU population (4-8%). This was associated with severity of illness at admission. Further work is warranted to understand the lasting effects of these new morbidities and mitigating interventions.

Abstract
Many important clinical questions remain unanswered in the practice of pediatric intensive care due to the lack of high-quality evidence. Although challenges exist in conducting research in pediatric intensive care units, identification of research priorities, interdisciplinary collaborations, innovative trial designs, and the use of common datasets and outcome measures helps to bring new knowledge to our field. The topic of "Research in PICUs" is extremely broad; therefore, this review focuses on a few common themes receiving increased attention in the literature, including research agendas, core outcome sets, precision medicine, and novel clinical trial strategies.

Abstract
The aim of this study was to study the effect of early nutritional assessment and nutritional support on immune function and clinical prognosis of critically ill children. 90 critically ill children at the same level of severity admitted to the pediatric intensive care unit (PICU) of our hospital (June 2019-June 2020) were chosen as the research objects and were equally separated into the experimental group and the control group by the random number table method. The children in the control group were admitted to the PICU according to the routine process, and the nutritional support was provided to the malnourished ones. After admission to the PICU, the children in the experimental group were given nutritional assessment, nutritional risk screening, and nutritional support according to the screening results. The PICU stay time and total hospitalization time of the experimental group were obviously shorter than those of the control group (P < 0.05), the hospitalization expenses of the experimental group were obviously lower than those of the control group (P < 0.05), the clinical outcomes and immune function of the experimental group were obviously better than those of the control group (P < 0.05), and the nutrition indicators of the experimental group were obviously higher than those of the control group (P < 0.05). Early nutritional assessment and nutritional support can effectively improve the immune function and reduce the incidence of adverse clinical outcomes of critically ill children, which are worthy of clinical application and promotion.

Evaluation of the neonatal sequential organ failure assessment and mortality risk in neonates with respiratory distress syndrome: A retrospective cohort study. Front Pediatr 2022; 10:911444.

Abstract
BACKGROUND Respiratory distress syndrome (RDS) is one of the leading causes of neonatal death in the neonatal intensive care unit (NICU). Previous studies have suggested that the development of neonatal RDS may be associated with inflammation and lead to organ dysfunction. The neonatal sequential organ failure assessment (nSOFA) scoring system is an operational definition of organ dysfunction, but whether it can be used to predict mortality in neonates RDS is unknown. The aim of this study was to clarify the performance of the nSOFA score in predicting mortality in patients with neonatal RDS, with the aim of broadening the clinical application of the nSOFA score. METHODS Neonates with RDS were identified from the Medical Information Mart for Intensive Care (MIMIC)-III database. Cox proportional hazards model were used to assess the association between nSOFA score and mortality. Propensity score matched analysis were used to assess the robustness of the analytical results. RESULTS In this study of 1,281 patients with RDS of which 57.2% were male, death occurred in 40 cases (3.1%). Patients with high nSOFA scores had a higher mortality rate of 10.7% compared with low nSOFA scores at 0.3%. After adjusting for confounding, multivariate Cox proportional risk analysis showed that an increase in nSOFA score was significantly associated with increased mortality in patients with RDS [adjusted Hazards Ratio (aHR): 1.48, 95% Confidence Interval (CI): 1.32-1.67; p < 0.001]. Similarly, the High nSOFA group was significantly associated with higher mortality in RDS patients (aHR: 19.35, 95% CI: 4.41-84.95; p < 0.001) compared with the low nSOFA group. CONCLUSION The nSOFA score was positively associated with the risk of mortality in cases of neonatal RDS in the NICU, where its use may help clinicians to quickly and accurately identify high risk neonates and implement more aggressive intervention.

Abstract
Abstract
Objectives This article described parents' experience and identifies outcomes important to parents following their child's critical illness.
Methods Semistructured interviews with 22 female and 4 male parents representing 26 critically ill children with predominately neurologic and respiratory diagnoses. Most children were younger than 5 years at discharge with a median (interquartile range) of 2 (2.0–3.0) years from discharge to interview.
Results Many children returned home with life-altering physical and cognitive disabilities requiring months to years of rehabilitation. Parents remembered feeling unprepared and facing an intense, chaotic time when the child first returned home. They described how they suddenly had to center their daily activities around the child's needs amidst competing needs of siblings and partners, and in some cases, the medicalization of the home. They recounted negotiating adjustments almost daily with insurance agencies, medical doctors and therapists, employers, the child, and other family members to keep the family functioning. In the long term, families developed a new norm, choosing to focus on what the child could still do rather than what they could not. Even if the child returned to baseline, parents remembered the adjustments made to keep the child alive and the family functioning.
Conclusion Heightened awareness of family experiences after pediatric critical illness will allow health care providers to improve family preparedness for the transition from hospital to home.

Abstract
OBJECTIVES Developing effective therapies to reduce morbidity and mortality requires knowing the responsible pathophysiologies and the therapeutic advances that are likely to be impactful. Our objective was to determine at the individual patient level the important pathophysiological processes and needed therapeutic additions and advances that could prevent or ameliorate morbidities and mortalities. DESIGN Structured chart review by pediatric intensivists of PICU children discharged with significant new morbidity or mortality to determine the pathophysiologies responsible for poor outcomes and needed therapeutic advances. SETTING Multicenter study (eight sites) from the Collaborative Pediatric Critical Care Research Network of general and cardiac PICUs. PATIENTS First PICU admission of patients from December 2011 to April 2013. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Two-hundred ninety-two patients were randomly selected from 681 patients discharged with significant new morbidity or mortality. The median age was 2.4 years, 233 (79.8%) were in medical/surgical ICUs, 59 (20.2%) were in cardiac ICUs. Sixty-five (22.3%) were surgical admissions. The outcomes included 117 deaths and 175 significant new morbidities. The most common pathophysiologies contributing to the poor outcomes were impaired substrate delivery (n = 158, 54.1%) and inflammation (n = 104, 35.6%). There were no strong correlations between the pathophysiologies and no remarkable clusters among them. The most common therapeutic needs involved new drugs (n = 149, 51.0%), cell regeneration (n = 115, 39.4%), and immune and inflammatory modulation (n = 79, 27.1%). As with the pathophysiologies, there was a lack of strong correlations or meaningful clusters in the suggested therapeutic needs. CONCLUSIONS There was no single dominant pathophysiology or cluster of pathophysiologies responsible for poor pediatric critical care outcomes. Therapeutic needs often involved therapies that are not close to implementation such as cell regeneration, improved organ transplant, improved extracorporeal support and artificial organs, and improved drugs.

Abstract
OBJECTIVES To determine the long-term (> 6 mo) functional status of PICU patients with significant new functional morbidities at hospital discharge. DESIGN Longitudinal cohort followed-up using structured chart reviews of electronic health records. SETTING Electronic health records of former PICU patients at seven sites. PATIENTS Randomly selected patients from the Trichotomous Outcome Prediction in Critical Care study discharged from the hospital with new functional status morbidity who had sufficient electronic health record data to determine functional status. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Long-term functional status was measured with the Functional Status Scale and categorized by comparison to hospital discharge Functional Status Scale. Improvement or new morbidity was based on a change in Functional Status Scale of greater than or equal to 2 in a single domain. Overall, 56% (n = 71) improved, 15% (n = 19) did not change, 9% (n = 11) developed a new morbidity, and 21% (n = 26) died. The shortest median follow-up time from PICU discharge was 1.4 years for those who died and the longest was 4.0 years for those improved. Functional status at baseline (pre-acute illness) was different among the outcome groups with those that improved having the highest frequency of baseline normal status or only mild dysfunction. Of the long-term survivors with improvement, 82% (n = 58) improved to normal status or mild dysfunction, 11% (n = 8) improved to moderate dysfunction, and 7% (n = 5) improved to severe dysfunction. Trauma patients improved and cancer patients died more frequently than other diagnoses. The long-term outcome groups were not associated with hospital discharge functional status. CONCLUSIONS A majority of PICU survivors discharged with significant new functional morbidity with follow-up after 6 or more months improved, many to normal status or only mild dysfunction, while 29% died or developed new morbidity. Of the long-term survivors, 70% had significant improvement after a median follow-up time of 4.0 years.
