RESUMO
OBJECTIVES: Having a child admitted to the PICU is a stressful experience for parents and can have long-term negative mental health consequences. The objective was to determine if formalized expectation setting and bundled consent for invasive procedures upon admission impacts the acute stress burden on parents. DESIGN: Prospective cluster randomized controlled trial. SETTING: Single-center, tertiary PICU. SUBJECTS: Parents/guardians of patients, 0-18 years old, admitted to PICU. INTERVENTIONS: During experimental weeks, all patients admitted to PICU were bundled-consented for common procedures and given a novel unit introductory letter and "Common Procedures Explained" document. During control weeks, all patients were consented for invasive procedures with separate consents for each procedure. Parents then completed a demographic survey and Stress Overload Scale-Short (SOS-S) 48-72 hours after their child's admission. For each participant, the SOS-S generates a Personal Vulnerability (PV) score and an Event Load (EL) score. Parents' perception of the life-threatening nature of their child's condition was also evaluated. MEASUREMENTS AND MAIN RESULTS: Over 73 weeks, 1,882 patients were screened and 261 consented to the SOS-S. Median PV score was 10.4 in the control group and 9.1 in the experimental group ( p = 0.15). Median EL score was 11.3 for the control group and 10.5 in the experimental group ( p = 0.42). Adjusting for demographic variables and severity of illness, there was no independent association between either PV or EL and bundled consent. However, a parent's perception of threat-to-life was significantly related to the allocated group ( p = 0.036), which resulted in a decreased percentage of parents who rated their child's illness as "Extremely" life-threatening (experimental group, 17% vs control group, 26%). CONCLUSIONS: This study did not demonstrate a decrease in stress when bundled consent was obtained. However, this intervention decreased the parents' perceived severity of illness. Further multicenter studies are needed to evaluate the effects of bundled consent on parents.

BACKGROUND: Understanding factors that impact tissue oxygen extraction may guide red blood cell (RBC) transfusion decision making in preterm infants. Our objective was to assess the influence of enteral feeding and anemia on cerebral and mesenteric oxygen saturation (Csat and Msat) and fractional tissue oxygen extraction (cFTOE and mFTOE) over the entire time course of RBC transfusion. STUDY DESIGN AND METHODS: Preterm, very low-birth-weight infants receiving RBC transfusions at a single center were enrolled. Near-infrared spectroscopy sensors measured Csat and Msat levels from an hour before transfusion to 24 hours after. During this period, changes in Csat, Msat, cFTOE, and mFTOE were described, and their association with enteral feeding status and pretransfusion degree of anemia were assessed using generalized estimating equations. RESULTS: RBC transfusion data from 31 preterm infants were included. Infants receiving enteral feeds exhibited lower pretransfusion Msat. Infants with pretransfusion hematocrit greater than 30% exhibited higher pretransfusion Csat and lower pretransfusion cFTOE. Such differences in baseline measurements persisted through 24 hours after transfusion. However, no statistically significant differences in oxygenation measures over time by enteral feeding or anemia status were identified. CONCLUSION: Compared to NPO, enteral feeding was associated with lower Msat; anemia (hematocrit ≤30%) was associated with lower Csat and higher cFTOE. Over the time course of RBC transfusion, trajectories of Csat, Msat, cFTOE and mFTOE did not differ by enteral feeding or anemia status.

BACKGROUND: The impact of human milk use on racial/ethnic disparities in necrotizing enterocolitis (NEC) incidence is unknown. METHODS: Trends in NEC incidence and human milk use at discharge were evaluated by race/ethnicity among 47,112 very low birth weight infants born in California from 2008 to 2017. We interrogated the association between race/ethnicity and NEC using multilevel regression analysis, and evaluated the effect of human milk use at discharge on the relationship between race/ethnicity and NEC using mediation analysis. RESULTS: Annual NEC incidence declined across all racial/ethnic groups from an aggregate average of 4.8% in 2008 to 2.6% in 2017. Human milk use at discharge increased over the time period across all racial groups, and non-Hispanic (NH) black infants received the least human milk each year. In multivariable analyses, Hispanic ethnicity (odds ratio (OR) 1.27, 95% confidence interval (CI) 1.02-1.57) and Asian or Pacific Islander race (OR 1.35, 95% CI 1.01-1.80) were each associated with higher odds of NEC, while the association of NH black race with NEC was attenuated after adding human milk use at discharge to the model. Mediation analysis revealed that human milk use at discharge accounted for 22% of the total risk of NEC in non-white vs. white infants, and 44% in black vs. white infants. CONCLUSIONS: Although NEC incidence has declined substantially over the past decade, a sizable racial/ethnic disparity persists. Quality improvement initiatives augmenting human milk use may further reduce the incidence of NEC in vulnerable populations.

Fluid overload is a common complication of critical illness, associated with increased morbidity and mortality. Pulmonary fluid status is difficult to evaluate clinically and many clinicians utilize chest X-ray (CXR) to identify fluid overload. Adult data have shown lung ultrasound (LUS) to be a more sensitive modality. Our objective was to determine the performance of LUS for detecting fluid overload, with comparison to CXR, in critically ill children. We conducted a systematic review using multiple electronic databases and included studies from inception to November 15, 2020. The sensitivity and specificity of each test were evaluated. Out of 1,209 studies screened, 4 met eligibility criteria. Overall, CXR is reported to have low sensitivity (44-58%) and moderate specificity (52-94%) to detect fluid overload, while LUS is reported to have high sensitivity (90-100%) and specificity (94-100%). Overall, the quality of evidence was moderate, and the gold standard was different in each study. Our systematic review suggests LUS is more sensitive and specific than CXR to identify pulmonary fluid overload in critically ill children. Considering the clinical burden of fluid overload and the relative ease of obtaining LUS, further evaluation of LUS to diagnose volume overload is warranted.
RESUMO
OBJECTIVE: Given that regionalization of extremely preterm births (EPTBs) is associated with improved infant outcomes, we assessed between-hospital variation in EPTB stratified by hospital level of neonatal care, and determined the proportion of variance explained by differences in maternal and hospital factors. STUDY DESIGN: We assessed 7,046,253 births in California from 1997 to 2011, using hospital discharge, birth, and death certificate data. We estimated the association between maternal and hospital factors and EPTB using multivariable regression, calculated hospital-specific EPTB frequencies, and estimated between-hospital variances and median odds ratios, stratified by hospital level of care. RESULT: Hospital frequencies of EPTB ranged from 0% to 2.5%. Between-hospital EPTB frequencies varied substantially, despite stratifying by hospital level of care and accounting for confounding factors. CONCLUSION: Our results demonstrate differences in EPTBs among hospitals with level 1 and 2 neonatal care, an area to target for future research and quality improvement.

BACKGROUND: In the USA, the mortality rate from traffic injury is higher in rural and in southern regions, for reasons that are not well understood. METHODS: For 1754 (56%) of the 3142 US counties, we obtained data allowing for separation of the deaths/population rate into deaths/injury, injuries/crash, crashes/exposure and exposure/population, with exposure measured as vehicle miles travelled. A 'decomposition method' proposed by Li and Baker was extended to study how the contributions of these components were affected by three measures of rural location, as well as southern location. RESULTS: The method of Li and Baker extended without difficulty to include non-binary effects and multiple exposures. Deaths/injury was by far the most important determinant in the county-to-county variation in deaths/population, and accounted for the greatest portion of the rural/urban disparity. After controlling for the rural effect, injuries/crash accounted for most of the southern/northern disparity. CONCLUSIONS: The increased mortality rate from traffic injury in rural areas can be attributed to the increased probability of death given that a person has been injured, possibly due to challenges faced by emergency medical response systems. In southern areas, there is an increased probability of injury given that a person has crashed, possibly due to differences in vehicle, road, or driving conditions.

Necrotizing enterocolitis (NEC) is a devastating disease of prematurity, with no current method for early diagnosis. Diagnosis is particularly challenging, frequently occurring after the disease has progressed to the point of significant and often irreversible intestinal damage. Biomarker research has tremendous potential to advance clinical management of NEC and our understanding of its pathogenesis. This review discusses the need for novel biomarkers in NEC management, evaluates studies investigating such biomarkers, and explains the difficulties associated with translating biomarker discovery into clinical use.

OBJECTIVE: To evaluate the relationship between prenatal and postnatal inflammation-related risk factors and severe retinopathy of prematurity (ROP). STUDY DESIGN: The study included infants born <30 weeks in California from 2007 to 2011. Multivariable log-binomial regression was used to assess the association between prenatal and postnatal inflammation-related exposures and severe ROP, defined as stage 3-5 or surgery for ROP. RESULTS: Of 14,816 infants, 10.8% developed severe ROP. Though prenatal inflammation-related risk factors were initially associated with severe ROP, after accounting for the effect of these risk factors on gestational age at birth through mediation analysis, the association was non-significant (P = 0.6). Postnatal factors associated with severe ROP included prolonged oxygen exposure, sepsis, intraventricular hemorrhage, and necrotizing enterocolitis. CONCLUSION: Postnatal inflammation-related factors were associated with severe ROP more strongly than prenatal factors. The association between prenatal inflammation-related factors and ROP was explained by earlier gestational age in infants exposed to prenatal inflammation.

OBJECTIVE: Neonatal coronary thrombosis is a rarely reported disorder, with variable outcomes described. This study assessed the feasibility and safety of an institutional protocol using tissue plasminogen activator (tPA) administration for the treatment of neonatal coronary artery thrombi. METHODS: They reviewed the outcome of three neonates with clinical evidence of myocardial infarction secondary to coronary thrombosis. All three underwent the tPA treatment protocol. RESULTS: The three described cases presented at 5 hours, 15 hours, and 10 days of life. The patients identified underwent the tPA protocol at least once. There was clinical evidence of improvement in coronary flow, as well as demonstration of increased left ventricular function and decreased mitral regurgitation. No major adverse events occurred. CONCLUSION: Thrombolytic therapy with this tPA protocol may be safe and effective in treating neonates with coronary thrombosis.

OBJECTIVE: To estimate the influence of prior oral contraceptive pill (OCP) use on future diagnosis of endometriosis in young women. DESIGN: Prospective cohort study, the Australian Longitudinal Study on Women's Health. SETTING: Community-based sample. PATIENT(S): 9,585 women age 18-23 at study onset. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Risk of self-reported endometriosis estimated with Cox proportional-hazards regression with time-dependent covariates. RESULT(S): Compared with never users, endometriosis hazard ratios in nulliparous women with <5 years and ≥ 5 years of OCP use (preceding diagnosis) were 1.8 (95% CI, 1.30-2.53) and 2.3 (95% CI, 1.59-3.40), respectively. Similar risk was seen in both women reporting infertility and unsure fertility. In parous women with <5 years of use, the hazard ratio for endometriosis was 0.41 (95% CI, 0.15-0.56) and for ≥ 5 years of use was 0.45 (95% CI, 0.16-1.23). Women reporting early noncontraceptive OCP use had a twofold higher risk (odds ratio 2.07; 95% CI, 1.72-2.51). CONCLUSION(S): Prior OCP exposure reduces the risk of diagnosis of endometriosis in parous women but increases it among nulliparous women; these associations appear unaffected by fertility status. An increased risk of endometriosis diagnosis seen in women reporting early noncontraceptive OCP use may explain some of the positive OCP risk seen in nulliparous women.
