RESUMEN
OBJECTIVE: To assess the effect of cardiovascular medications on the neurodevelopment of preterm infants, as measured by calculated cumulative time of vasoactive-inotropic score (VISct). METHODS: A retrospective study was conducted on preterm infants who developed significant hypotension defined as a mean BP more than 2SDs below the mean for GA and received treatment with durationâ>â6 hours for each hypotensive episode, we calculated the vasoactive inotropic score (VIS) and cumulative exposure to cardiovascular medications over time (VISct). The composite Bayley III was reported from the high-risk follow-up clinic for the surviving infants between 18 to 21 months corrected age. RESULTS: VISct was significantly higher in infants with abnormal neurodevelopment. Cognitive Bayley was the most affected component with median (IQR) VISct 882.5(249,2047) versus 309(143,471) (p-value 0.012), followed by language function with VISct 786(261,1563.5), versus 343(106.75,473.75) (p-value 0.016) when those with Bayley III <85 were compared with those with normal Bayley IIIs. CONCLUSION: High VISct scores may have negative effect on cognitive and language neurodevelopmental outcomes.

Background: The benefits of facilitating breastmilk feeding and close contact between mother and neonate (family-centred care; FCC) in the perinatal period are well-established. The aim of this study was to determine how the delivery of FCC practices were impacted for neonates born to mothers with perinatal SARS-CoV-2 infection during the COVID-19 pandemic. Methods: Neonates born to mothers with confirmed SARS-CoV-2 infection during pregnancy were identified from the 'EsPnIC Covid paEdiatric NeonaTal REgistry' (EPICENTRE) multinational cohort between 10 March 2020 and 20 October 2021. The EPICENTRE cohort collected prospective data on FCC practices. Rooming-in and breastmilk feeding practice were the main outcomes, and factors influencing each were determined. Other outcomes included mother-baby physical contact prior to separation and the pattern of FCC components relative to time and local site guidelines. Findings: 692 mother-baby dyads (13 sites, 10 countries) were analysed. 27 (5%) neonates were positive for SARS-CoV-2 (14 (52%) asymptomatic). Most sites had policies that encouraged FCC during perinatal SARS-CoV-2 infection for most of the reporting period. 311 (46%) neonates roomed-in with their mother during the admission. Rooming-in increased over time from 23% in March-June 2020 to 74% in January-March 2021 (boreal season). 330 (93%) of the 369 separated neonates had no FCC physical contact with their mother prior, and 319 (86%) were asymptomatic. Maternal breastmilk was used for feeding in 354 (53%) neonates, increasing from 23% to 70% between March-June 2020 and January-March 2021. FCC was most impacted when mothers had symptomatic COVID-19 at birth. Interpretation: This is the largest report of global FCC practice during the COVID-19 pandemic to date. The COVID-19 pandemic may have impacted FCC despite low perinatal transmission rates. Fortunately, clinicians appear to have adapted to allow more FCC delivery as the COVID-19 pandemic progressed.

RESUMEN
OBJECTIVE: To validate the vasoactive inotropic score as a predictor of the severity of compromised systemic circulation and mortality in preterm infants. METHODS: A retrospective study was conducted on preterm infants with Compromised systemic circulation [hypotension±lactic acidosis±oliguria] who received a cardiovascular support, we calculated the vasoactive inotropic score (VIS) and cumulative exposure to cardiovascular medications over time (VISct). Receiver operator curve was constructed to predict the primary outcome which was death & refractory hypotension. RESULTS: VIS had an area under the curve of 0.73 (95% CI 0.85-0.98, pâ<â0.001). A VIS cut off of 25 has sensitivity and specificity of 66% and 92%, and positive and negative predictive values of 78.5% and 83%, respectively. CONCLUSION: High VIS predicts the severity of Compromised systemic circulation and mortality rate in preterm infants.

Vein of Galen malformation results in predictable changes in physiology which exist on a continuum. Severe pulmonary hypertension may present as hypoxemia; however, excessive reduction in pulmonary vascular resistance may precipitate progressive pulmonary overcirculation and impaired systemic blood flow. Right ventricular performance and the patency and direction of the ductus arteriosus may play a crucial role in postductal organ perfusion. Physiological stabilization may be complex and variable over time. The utilization of targeted neonatal echocardiography to guide treatment decisions may improve the ability to provide therapy tailored to the specific disease pathophysiology and monitor serially as conditions change. An enhanced approach to physiological stabilization may reduce the risk of unexpected decompensation and allow for thoughtful, controlled endovascular embolization in appropriate candidates.
RESUMEN
BACKGROUND: A clinically significant patent ductus arteriosus (PDA) is associated with significant morbidity and mortality in premature newborns. Symptomatic PDAs are often treated with prostaglandin synthesis inhibitors (PSI), but controversy remains if PSIs should also be used to manage early, asymptomatic PDAs. OBJECTIVE: To systematically identify, critically appraise, and evaluate the efficacy and safety of pharmacological management of pre-symptomatic PDA in preterm newborns after confirmed patency by echocardiography. STUDY DESIGN: Systematic review and meta-analysis. SEARCH METHODS: We searched MEDLINE (Ovid), EMBASE (Ovid), Cochrane Central Register of Controlled Trials (Wiley), from date of inception to February 2017. Supplemental searching was performed in Scopus and Web of Science to identify additional relevant citations. We also searched conference proceedings, reference lists of relevant articles and the WHO International Clinical Trials Registry Platform (ICTRP). SELECTION CRITERIA: We included only randomized controlled trials (RCTs) that compared the use of indomethacin or ibuprofen to placebo for treatment of pre-symptomatic PDA in preterm newborns (<32 weeks gestational age and <1500gms). DATA COLLECTION AND ANALYSIS: Two reviewers independently selected trials, assessed risk of bias and extracted trial-level data. Outcomes are reported as risk ratios from random-effects models. Absolute risk reduction (ARR) is additionally reported for significant outcomes.We included seven trials (466 newborns). Targeted medical treatment did not significantly reduce mortality rates (RR 0.85, 95% CI 0.50 to 1.43; ARR -2.38%, 95% CI -8.04% to 3.29%; I2 0% 6 studies; 442 newborns), but it did significantly reduce the overall incidence of developing symptomatic PDA (RR 0.39, 95% CI 0.21 to 0.73; ARR -34.3%, 95% CI -50.8% to -17.8%; I2 0%; 3 studies; 97 newborns) compared to placebo. Other efficacy or safety outcomes were not significantly different. CONCLUSIONS: Targeted medical treatment of pre-symptomatic PDA decreases the incidence of developing symptomatic PDA, but not neonatal mortality. Further studies are essential to confirm these results.

OBJECTIVE: To study the impact of integrated evaluation of hemodynamics (IEH) using targeted neonatal echocardiography, together with regional tissue oxygenation, fractional oxygen extraction using near-infrared spectroscopy on the management of infants with compromised hemodynamics. STUDY DESIGN: Retrospective cohort comparison of two groups of infants with compromised hemodynamics. EPOCH 1: did not undergo IEH (January 2012 to March 2014); EPOCH 2: underwent IEH (April 2014 to December 2015). The primary outcome was the time to recovery. RESULTS: In all, 340 infants were included; 158 underwent IEH with a median (IQR) of 2 (1 to 3) evaluations per infant. Reasons for assessment included PDA (60%), compromised systemic circulation (14%) and clinically suspected pulmonary hypertension (22%). The time to recovery was shorter in IEH group in patients with compromised systemic circulation median (IQR), 32 h (24 to 63) compared with none IEH group 71 h (36 to 96), pulmonary hypertension 63 h (14.2 to 102) in IEH group compared with 68 h (24 to 240) in none IEH group, there were fewer PDA-related complications in preterm infants with PDA in IEH group. CONCLUSION: IEH was associated with shorter time to clinical recovery in infants with compromised hemodynamics.
