This research study explored changes in family-centered care practices for hospitalized infants and families due to the COVID-19 pandemic. This exploratory descriptive study used a 49-item online survey, distributed to health care professionals working with hospitalized infants and families. The sample consisted of 96 participants from 22 countries. Prior to the COVID-19 pandemic, 87% of units welcomed families and 92% encouraged skin-to-skin care. During the pandemic, family presence was restricted in 83% of units, while participation in infant care was restricted in 32%. Medium-sized (20–40 beds) units applied less restriction than small (<20 beds) units (p = 0.03). Units with single-family rooms that did not restrict parental presence, implemented fewer restrictions regarding parents’ active participation in care (p = 0.02). Restrictions to families were not affected by geographic infection rates or developmental care education of health care professionals. Restrictions during the pandemic increased separation between the infant and family.

Preterm infants with severe brain injury are at high risk for poor outcomes and, therefore, may benefit from developmental care modalities such as music therapy (MT). In this prospective, randomized intervention, preterm infants with severe brain injury (grade 3 or 4 intraventricular hemorrhage or periventricular leukomalacia) who underwent skin-to-skin contact (SSC) with or without maternal singing during MT were evaluated for physiological responses, including autonomic nervous system stability (low frequency (LF)/high frequency (HF) power), heart rate, respiratory rate, oxygen saturation, and behavioral state. Maternal anxiety state and physiological data were also evaluated. A total of 35 preterm infants with severe brain injuries were included in the study analysis. Higher mean ± standard deviation (SD) LF/HF ratio (1.8 ± 0.7 vs. 1.1 ± 0.25, p = 0.01), higher mean ± SD heart rate (145 ± 15 vs. 132 ± 12 beats per minute, p = 0.04), higher median (interquartile range) infant behavioral state (NIDCAP manual for naturalistic observation and the Brazelton Neonatal Behavioral Assessment) score (3 (2–5) vs. 1 (1–3), p = 0.03), and higher mean ± SD maternal anxiety (state-trait anxiety inventory) score (39.1 ± 10.4 vs. 31.5 ± 7.3, p = 0.04) were documented in SSC combined with maternal singing during MT, as compared to SSC alone.Conclusion: Maternal singing during MT for preterm infants with severe brain injury induces physiological and behavioral instability and increases maternal anxiety during NICU hospitalization. A unique MT intervention should be designed for preterm infants with severe brain injury and their mothers.What is Known:• Preterm infants with severe brain injury are at high risk for poor outcomes.• Music therapy benefits brain development of preterm infants without severe brain injury, however it is unknown whether maternal singing during music therapy for preterm infants with severe brain injury is beneficial.What is New:• Maternal singing during music therapy for preterm infants with severe brain injury induces physiological and behavioral instability and increases maternal anxiety during NICU hospitalization.• A unique music therapy intervention should be designed for preterm infants with severe brain injury and their mothers.

We aimed to compare the effect of 12-week feeding of commercially available infant formulas with different percentages of palmitic acid at sn -2 (beta-palmitate) on anthropometric measures and bone strength of term infants. It was hypothesized that feeding infants with high beta-palmitate (HBP) formula will enhance their bone speed of sound (SOS). Eighty-three infants appropriate for gestational age participated in the study; of these, 58 were formula-fed and 25 breast-fed infants, serving as a reference group. The formula-fed infants were randomly assigned to receive HBP formula (43 % of the palmitic acid is esterified to the middle position of the glycerol backbone, study group; n  = 30) or regular formula with low-beta palmitate (LBP, 14 % of the palmitic acid is esterified to the middle position of the glycerol backbone, n  = 28). Sixty-six infants completed the 12-week study. Anthropometric and quantitative ultrasound measurements of bone SOS for assessment of bone strength were performed at randomization and at 6 and 12 weeks postnatal age. At randomization, gestational age, birth weight, and bone SOS were comparable between the three groups. At 12 weeks postnatal age, the mean bone SOS of the HBP group was significantly higher than that of the LBP group (2,896 ± 133 vs. 2,825 ± 79 m/s respectively, P  = 0.049) and comparable with that of the breast-fed group (2,875 ± 85 m/s). We concluded that infants consuming HBP formula had changes in bone SOS that were comparable to those of infants consuming breast milk and favorable compared to infants consuming LBP formula.

Vitamin D plays a key role in regulating calcium and phosphate metabolism. However, whether maternal vitamin D levels affect fetal bone strength is unclear. This study assessed correlations between maternal 25(OH)D status and neonatal bone strength 25(OH)D levels, these were measured in the maternal and infant cord blood of 81 mother–infant dyads. Bone strength was measured using a quantitative ultrasound (QUS) of tibial bone speed of sound (SOS). Maternal vitamin D intake, medical history and lifestyle were evaluated from questionnaires. Maternal 25(OH)D levels were deficient (<25 nmol/L) in 24.7%, insufficient (25–50 nmol/L) in 37% and sufficient (>50 nmol/L) in 38.3%. The maternal and cord blood 25(OH)D levels correlated (r = 0.85, p < 0.001). Cord blood levels (57.9 ± 33.5 nmol/L) were higher than the maternal blood levels (46.3 ± 23.2: p < 0.001). The mean SOS was 3042 ± 130 m/s. The neonatal SOS and 25(OH)D levels were not correlated. The mean bone SOS levels were comparable in the three maternal and cord blood 25(OH)D groups. No correlation was found between the maternal 25(OH)D levels and the neonatal anthropometrics. Although the 25(OH)D levels were higher in Jewish mothers than they were in Muslim mothers (51.1 ± 22.6 nmol/L vs. 24 ± 14.7 nmol/L, respectively: p = 0.002) and in those who took supplemental vitamin D, the bone SOS levels were comparable. In conclusion, maternal vitamin D levels correlate with cord levels but do not affect bone strength or growth parameters.

Introduction: There is no agreement regarding the best method for tube-feeding preterm infants. Few studies, to date, have evaluated the influence of different methods of enteral feeding on intestinal oxygenation. The use of near-infrared spectroscopy (NIRS) has permitted the noninvasive measurement of splanchnic regional oxygenation (rSO2S) in different clinical conditions. The aim of this prospective, single-center study was to compare rSO2S during continuous versus bolus feeding among stable preterm infants. Methods: Twenty-one preterm infants, less than 32 weeks gestation and appropriate for gestational age, were enrolled. All infants were clinically stable and on full tube feedings. Each infant received a bolus feeding initially (20 min duration), and after 3 h, a continuous feeding (5 h duration). Infants were evaluated 30 min before and 30 min after the bolus and continuous feedings. The regional splanchnic saturation (rSO2S) was measured using near-infrared spectroscopy (NIRS) technology and systemic saturation was measured with pulse oximetry. From these measurements, we calculated the splanchnic fractional oxygen extraction ratio (FOES) for each of the four intervals. Results: rSO2S decreased after continuous vs. bolus feeding (p = 0.025), while there was a trend toward decreased SaO2 after bolus feeding (p = 0.055). The FOES, which reflects intestinal oxygen extraction, was not affected by the feeding mode (p = 0.129). Discussion/Conclusion: Continuous vs. bolus feeding decreases rSO2S but does not affect oxygen extraction by intestinal tissue; after bolus feeding there was a trend towards decreased systemic saturation.

ObjectiveTo examine the reliability of a novel ultrasound (US) method for assessment of endotracheal tube (ETT) position in neonates.DesignProspective, observational, single-centre, feasibility study.SettingLevel III neonatal intensive care unit.PatientsTerm and preterm neonates requiring endotracheal intubation.InterventionUS measurement of the ETT tip to right pulmonary artery (RPA) distance was used to determine ETT position according to one-fourth to three-fourths estimated tracheal length for weight. US demonstration of pleural sliding and diaphragmatic movement was also assessed. Chest radiography (CXR) was performed following each intubation.Main outcome measuresAgreement between US assessment of ETT tip position and CXR served as the gold standard. Sensitivity, specificity, positive and negative predictive values for each US method and correlation between ETT tip to RPA distance on US, and ETT tip to carina distance on CXR were assessed.ResultsForty-two US studies were performed on 33 intubated neonates. US evaluation of ETT-RPA distance identified 100% of ETTs positioned correctly: 77% deep and 80% high, demonstrating strong agreement with CXR (kappa=0.822). Sensitivity was 78%, specificity 100%, positive predictive value 100% and negative predictive value 86%. US ETT-RPA distance strongly correlated with CXR ETT-carina distance (r=0.826). No significant agreement was found between CXR and US assessment of pleural sliding and diaphragmatic movement. No adverse events were encountered during US scans.ConclusionUS evaluation of ETT-RPA distance demonstrated excellent accuracy for determining ETT position in neonates compared with CXR. More research is needed to support its feasibility in clinical settings.

The success rate of conservative treatment for children with uncomplicated appendicitis was prospectively evaluated among 197 children. All who received intravenous antibiotics for 3–5 days, and if symptoms resolved, were discharged home on oral antibiotics for 5 days. Failure rate, symptoms, laboratory signs, and sonographic findings were evaluated for prognostic markers of treatment failure. Children were followed for 18 months. The success rate of conservative treatment was 87%, with shorter hospital stays compared to children who eventually needed surgery (72 [60–84] vs. 84 h [72–126], P  = 0.001). Vomiting and/or nausea and intraluminal fluid on sonography were the only prognostic signs of failed treatment ( P  = 0.028 and P  = 0.0001, respectively). After multi-regression analysis, intraluminal fluid was the only prognostic sign for failed treatment (odds ratio = 10.2; 95% CI 3.3–31.8, P  = 0.001). Patients who failed conservative treatment were successfully operated without significant morbidity. Pathology findings were compatible with acute or subacute inflammation in 94% of operated AA, with no perforated appendices. Conclusion : When applying rigorous criteria for children with uncomplicated appendicitis, a high success rate can be achieved with conservative treatment. Those who fail conservative treatment have a benign medical course without serious complications. Intraluminal fluid may increase risk for conservative treatment failure. What is Known: • Conservative treatment in uncomplicated acute appendicitis is a reasonable alternative to appendectomy . What is New: • Using rigorous criteria for conservative treatment in uncomplicated acute appendicitis is safe and feasible . • Intraluminal fluid should be considered a contraindication to conservative treatment .

PurposeAppendectomy versus conservative antibiotic treatment (CAT) for children with acute uncomplicated appendicitis (AUA) remains unresolved, with concerns regarding the practicality of CAT. We analyzed our center’s experience with CAT for AUA, using a protocol with strict inclusion, exclusion and treatment criteria.MethodsNon-randomized, prospective cohort study included all children admitted betwee 2014 and 2016, with clinical and laboratory tests suspicious for AUA. Data collected included clinical signs and symptoms; laboratory, ultrasound and pathology results. Follow-up was conducted through clinic visits, telephone conversations and national registry analysis.ResultsIncluded in CAT: 362 children, 19 underwent appendectomy within 1–2 days. Overall, 75 were readmitted for recurrent acute appendicitis during 22 months (6–43) follow-up. Thirty were treated successfully with antibiotics a second time. The remaining 45 had appendectomy. Overall, 86.8% underwent CAT with no surgery. Histology of all recurrent AUA revealed no perforations.ConclusionWe confirm the feasibility of conservative management of AUA in children. A rigorous diagnostic plan with strict inclusion and exclusion criteria will lead to high success rate of CAT with a strong safety profile. CAT does not compete with surgery or render appendectomy unnecessary. It is a safe alternative to surgery in selected cases.

Neonatal nutritional supplements are widely used to improve growth and development but may increase risk of later metabolic disease, and effects may differ by sex. We assessed effects of supplements on later development and metabolism. We searched databases and clinical trials registers up to April 2019. Participant-level data from randomised trials were included if the intention was to increase macronutrient intake to improve growth or development of infants born preterm or small-for-gestational-age. Co-primary outcomes were cognitive impairment and metabolic risk. Supplementation did not alter cognitive impairment in toddlers (13 trials, n = 1410; adjusted relative risk (aRR) 0.88 [95% CI 0.68, 1.13]; p = 0.31) or older ages, nor alter metabolic risk beyond 3 years (5 trials, n = 438; aRR 0.94 [0.76, 1.17]; p = 0.59). However, supplementation reduced motor impairment in toddlers (13 trials, n = 1406; aRR 0.76 [0.60, 0.97]; p = 0.03), and improved motor scores overall (13 trials, n = 1406; adjusted mean difference 1.57 [0.14, 2.99]; p = 0.03) and in girls not boys (p = 0.03 for interaction). Supplementation lowered triglyceride concentrations but did not affect other metabolic outcomes (high-density and low-density lipoproteins, cholesterol, fasting glucose, blood pressure, body mass index). Macronutrient supplementation for infants born small may not alter later cognitive function or metabolic risk, but may improve early motor function, especially for girls.

We aimed to assess whether a twice daily assisted exercise interventional program will have a greater effect on bone strength compared to a once daily intervention or no intervention in very low birth weight (VLBW) preterm infants. Thirty-four very VLBW preterm infants (mean BW 1217 ± 55 g and mean gestational age 28.6 ± 1.1 weeks) were randomly assigned into one of three study groups: twice daily interventions ( n  = 13), a once daily intervention ( n  = 11), and no intervention (control, n  = 10). The intervention was initiated at a mean of 8 ± 2.4 days of life and continued for 4 weeks. It included passive extension and flexion range-of-motion exercise of the upper and lower extremities. Bone strength was measured at enrollment and after 2 and 4 weeks using quantitative ultrasound of tibial bone speed of sound (SOS, Sunlight Omnisense™). At enrollment, the mean bone SOS was comparable between the twice daily interventions, once daily intervention and control groups (2918 ± 78, 2943 ± 119, and 2910 ± 48 m/s, respectively). As expected, the bone SOS declined in all groups during the study period (−23.6 ± 24, −68.8 ± 28, and −115.8 ± 30 m/s, respectively, p  < 0.05), with a significantly attenuated decrease in bone strength in the twice daily intervention group ( p  = 0.03). A twice daily intervention program of assisted range-of-motion exercise attenuates the decrease in bone strength and may decrease the risk of osteopenia and future fractures in VLBW preterm infants.
