Observational StudyCardiac Dysfunction Identified by Strain Echocardiography Is Associated With Illness Severity in Pediatric Sepsis.
Sepsis-induced myocardial dysfunction has been associated with illness severity and mortality in pediatrics. Although early sepsis-induced myocardial dysfunction diagnosis could aid in hemodynamic management, current echocardiographic metrics for assessing biventricular function are limited in detecting early impairment. Strain echocardiography is a validated quantitative measure that can detect subtle perturbations in left ventricular and right ventricular function. This investigation evaluates the utility of strain echocardiography in pediatric sepsis and compares with to conventional methods. ⋯ Compared with healthy controls, patients with severe sepsis demonstrated abnormal left ventricular strain (left ventricular longitudinal strain: -13.0% ± 0.72; p = 0.04 and left ventricular circumferential strain: -16.5% ± 0.99; p = 0.046) and right ventricular (right ventricular longitudinal strain = -14.3% ± 6.3; p < 0.01) despite normal fractional shortening (36.0% ± 1.6 vs 38.1% ± 1.1; p = 0.5129) and ejection fraction (60.7% ± 2.2 vs 65.3% ± 1.5; p = 0.33). There was significant association between depressed left ventricular longitudinal strain and increased Vasotrope-Inotrope Score (r = 0.52; p = 0.034). Worsening left ventricular circumferential strain was correlated with higher lactate (r = 0.31; p = 0.03) and higher Pediatric Risk of Mortality-III score (r = 0.39; p < 0.01). Depressed right ventricular longitudinal strain was associated with elevated pediatric multiple organ dysfunction score (r = 0.44; p < 0.01) CONCLUSIONS:: Compared with healthy children, pediatric septic patients demonstrated abnormal left ventricular and right ventricular strain concerning for early signs of cardiac dysfunction. This was despite having normal ejection fraction and fractional shortening. Abnormal strain was associated with abnormal severity of illness markers. Strain echocardiography may have utility as an early indicator of sepsis-induced myocardial dysfunction in pediatric sepsis.

Prevalence and Outcomes of Pediatric In-Hospital Cardiac Arrest Associated With Pulmonary Hypertension.
In adult in-hospital cardiac arrest, pulmonary hypertension is associated with worse outcomes, but pulmonary hypertension-associated in-hospital cardiac arrest has not been well studied in children. The objective of this study was to determine the prevalence of pulmonary hypertension among children with in-hospital cardiac arrest and its impact on outcomes. ⋯ Pulmonary hypertension physiology preceding pediatric in-hospital cardiac arrest may be more common than previously described. Among this cohort with a high frequency of inhaled nitric oxide treatment during cardiopulmonary resuscitation, pulmonary hypertension was not associated with survival outcomes.

Biomarkers of Inflammation and Lung Recovery in Extracorporeal Membrane Oxygenation Patients With Persistent Pulmonary Hypertension of the Newborn: A Feasibility Study.
Extracorporeal membrane oxygenation is a treatment for Persistent Pulmonary Hypertension of the Newborn with high mortality. ⋯ Clinical status at baseline and not levels of plasma-free hemoglobin or the systemic inflammatory response may determine the requirement for prolonged extracorporeal membrane oxygenation support in neonates.

Association Between Resilience and Psychological Morbidity in Parents of Critically Ill Children.
To determine whether parental resilience, measured at ICU admission, is associated with parent-reported symptoms of depression, anxiety, posttraumatic stress, and satisfaction with ICU care 3-5 weeks following ICU discharge. ⋯ Higher parental resilience is associated with fewer reported symptoms of anxiety, depression, and posttraumatic stress 3-5 weeks after ICU discharge. Parental resilience may impact parental post-ICU psychological morbidity. Measuring parental resilience could be one approach to identify parents at risk for post-ICU psychological morbidity. Future research into the impact of interventions designed to boost parental resilience is warranted.

Reactivation viremia is associated with adverse clinical outcomes and immune dysfunction in adults with sepsis. We determined the incidence of viremia and its association with clinical outcomes and immune paralysis phenotype in children with severe sepsis. ⋯ Children with severe sepsis had low rates of detectable viremia, which limited analyses of its association with clinical outcomes or immune paralysis phenotype. Given the rare occurrence of cytomegalovirus viremia, in particular, our study does not support a role for viremia as a biomarker of illness severity or as a modifiable risk factor of clinical outcomes for most patients. Future studies on the role of viremia in pediatric sepsis will need to consider the challenges posed by low rates of viremia in this population.
