Proportion of confluent B-Lines predicts respiratory support in term infants shortly after birth.

OBJECTIVE: To develop and evaluate the predictive value of a simplified lung ultrasound (LUS) method for forecasting respiratory support in term infants. METHODS: This observational, prospective, diagnostic accuracy study was conducted in a tertiary academic hospital between June and December 2023. A total of 361 neonates underwent LUS examination within 1 h of birth. The proportion of each LUS sign was utilized to predict their respiratory outcomes and compared with the LUS score model. After identifying the best predictive LUS sign, simplified models were created based on different scan regions. The optimal simplified model was selected by comparing its accuracy with both the full model and the LUS score model. RESULTS: After three days of follow-up, 91 infants required respiratory support, while 270 remained healthy. The proportion of confluent B-lines demonstrated high predictive accuracy for respiratory support, with an area under the curve (AUC) of 89.1% (95% confidence interval [CI]: 84.5-93.7%). The optimal simplified model involved scanning the R/L 1-4 region, yielding an AUC of 87.5% (95% CI: 82.6-92.3%). Both the full model and the optimal simplified model exhibited higher predictive accuracy compared to the LUS score model. The optimal cut-off value for the simplified model was determined to be 15.9%, with a sensitivity of 76.9% and specificity of 91.9%. CONCLUSIONS: The proportion of confluent B-lines in LUS can effectively predict the need for respiratory support in term infants shortly after birth and offers greater reliability than the LUS score model.

The effect of oral zinc sulfate supplementation on hospitalized infants with hyperbilirubinemia: a double-blind randomized clinical trial.

Previous investigations on the impact of oral zinc sulfate treatment on newborns' serum bilirubin levels have produced conflicting results. As a result, the goal of this clinical study was to evaluate how oral zinc sulfate affected the levels of serum bilirubin in term infants who were admitted to the neonatal intensive care unit. The study was conducted at the Neonatal Care Unit of Besat Hospital in Sanandaj, Kurdistan Province, as a double-blind randomized controlled trial. The participants included term infants (37-42 weeks of gestation) who required phototherapy and were admitted to the neonatal intensive care unit. A total of 290 infants were enrolled and randomly divided into two groups. The intervention group received oral zinc sulfate supplementation at a dosage of 1 mg/kg per day in addition to phototherapy, while the placebo group received an equivalent amount of placebo daily. Bilirubin measurements were obtained at the initiation of the intervention and subsequently every 24 h until discharge. The collected data were analyzed using STATA software version 17. After the infants were randomly allocated to the zinc-sulfate and placebo groups, the study outcomes, including the average changes in bilirubin levels after intervention, the hours of phototherapy, and the number of days of hospitalization, were analyzed and compared for a total of 160 infants in the zinc sulfate group and 130 infants in the placebo group. The reduction in bilirubin levels in infants receiving zinc sulfate was (- 3.75 ± 0.19 CI 95% - 4.12, - 3.37) and for placebo group was (- 1.81 ± 0.15 CI 95% - 2.12, - 1.50) 24 h after the intervention. Furthermore, 48 and 72 h following the intervention, bilirubin levels in the intervention group demonstrated a more substantial decline. The zinc sulfate group had a shorter hospital stay (2.13 ± 0.04 vs. 2.83 ± 1.42) and required less phototherapy hours than the placebo group (6.21 ± 2.16 vs. 8.78 ± 1.40).           Conclusions: Oral zinc sulfate supplementation in term neonates with hyperbilirubinemia decreased the level of bilirubin levels, duration of phototherapy, and hospital stay.           Trial registration: IRCT, IRCT20220806055625N1.

Short term effect of intravenous treprostinil in term and preterm infants with pulmonary hypertension.

BACKGROUND: Pulmonary hypertension (PH) is a life-threatening condition in newborns. We aimed to assess the clinical and echocardiographic responses of term and preterm infants to treprostinil. METHODS: This retrospective study included newborns diagnosed with PH and treated with treprostinil as additional therapy after inhaled nitric oxide administration in the neonatal intensive care unit of a tertiary center. Term and preterm infants were compared in terms of echocardiographic findings and clinical findings 4 weeks after treprostinil treatment. RESULTS: During the study period, 11 term and 18 preterm infants were diagnosed with PH and received treprostinil. There were no differences in the echocardiographic findings of interventricular septal deviation, direction of shunt, and ratio of estimated pulmonary artery pressure over systolic blood pressure. Congenital diaphragmatic hernia was the most common condition occurring upon PH diagnosis among term infants, while severe bronchopulmonary dysplasia was the most common in preterm infants. Improvements in echocardiographic findings were more pronounced in term infants than in preterm infants (100% vs. 55.6%, P = 0.012). The inhaled nitric oxide dose was gradually tapered for term infants and was lower than that for preterm infants at 1, 2, and 3 weeks after treprostinil. CONCLUSION: Intravenous treprostinil could be an adjuvant therapy option for term and preterm infants with PH, especially for those who cannot receive oral medication. The efficacy and safety of treprostinil in this population with PH should be investigated further.

Evaluating the Baby@Home program: Early discharge strategies for (pre)term infants are safe and benefit health outcomes.

AIM: Prolonged hospitalisation in the neonatal intensive care unit (NICU) can emotionally tax newborn infants and their families, resulting in developmental adversities and inadequate parent-infant bonding. This study aimed to assess the feasibility and value of the Baby@Home program in reducing prolonged hospital stays. METHODS: This is a retrospective cohort study of 26 infants from a tertiary neonatology department, using qualitative data (gathered through interviews with parents (n = 15) and professionals (n = 5)) and quantitative data (retrieved from medical records and the Luscii application). RESULTS: Our study included 26 newborn infants. 76% were premature, born at an average term of 35 weeks and 2 days. During the study period, all infants thrived, and only two adverse events occurred (an allergic reaction and respiratory incident necessitating readmission). Interviews were conducted based on six major themes concerning the feasibility and value of the program. Despite the challenges of application utilisation, the program's overall value was evident. CONCLUSION: The Baby@Home program effectively facilitated early discharge, promoted family reunification, and yielded favourable safety and health outcomes. Innovative solutions such as Baby@Home have the potential to pave the way for more sustainable and patient-centred care models.

Closed-loop oxygen system in late preterm/term, ventilated infants with different severities of respiratory disease.

AIM: To evaluate closed-loop automated oxygen control (CLAC) in ventilated infants >33 weeks of gestation with different respiratory disease severities. METHODS: Infants were studied on two consecutive days for 6 h each day. They were randomised to receive standard care or standard care with CLAC (Oxygenie) first. Analyses were performed of the results of infants with or without an FiO2 ≥ 0.3 and infants with congenital diaphragmatic hernia (CDH). RESULTS: Thirty-one infants with a median (IQR) gestational age of 37.9 (37.1-38.9) weeks were studied at a median postmenstrual age (IQR) of 38.9 (37.4-39.8) weeks. In infants with an FiO2 ≥ 0.3 (n = 8), CLAC increased the time spent in target oxygen range (92-96%) by 61.6% (p = 0.018), whereas in infants with an FiO2 < 0.3, the time in target was increased by 3.8% (p = 0.019). During CLAC, only infants with an FiO2 ≥ 0.3 spent less time in hyperoxemia (SpO2 > 96%) (p = 0.012) and hyperoxemic episodes were shorter (p = 0.012). In both groups, CLAC reduced the duration of desaturations (SpO2 < 92%, p < 0.001). In CDH infants, CLAC increased the time spent in target oxygen range by 34% (p = 0.036) and the median duration of desaturations was reduced (p = 0.028). CONCLUSION: CLAC may be more useful in infants with more severe respiratory distress.

Biochemical surveillance versus clinical observation of term infants born after prolonged rupture of membranes - A quality assurance initiative.

AIM: To examine whether biochemical surveillance vs clinical observation of term infants with prolonged rupture of membranes as a risk factor for early-onset sepsis is associated with differences in patient trajectories in maternity and neonatal intensive care units. METHODS: A retrospective study of live-born infants with gestational age ≥ 37 + 0 weeks born after prolonged rupture of membranes (≥24 h) in four Norwegian hospitals 2017-2019. Two hospitals used biochemical surveillance, and two used predominantly clinical observation to identify early-onset sepsis cases. RESULTS: The biochemical surveillance hospitals had more C-reactive protein measurements (p < 0.001), neonatal intensive care unit admissions (p < 0.001) and antibiotic treatment (p < 0.001). Hospitals using predominantly clinical observation initiated antibiotic treatment earlier in infants with suspected early-onset sepsis (p = 0.04) but not in infants fulfilling early-onset sepsis diagnostic criteria (p = 0.09). There was no difference in antibiotic treatment duration (p = 0.59), fraction of infants fulfilling early-onset sepsis diagnostic criteria (p = 0.49) or length of hospitalisation (p = 0.30), and no early-onset sepsis-related adverse outcomes. CONCLUSION: The biochemical surveillance hospitals had more C-reactive protein measurements, but there was no difference in antibiotic treatment duration, early-onset sepsis cases, length of hospitalisation or adverse outcomes. Personnel resources needed for clinical surveillance should be weighed against the limitation of potentially painful procedures.

Closed-loop automated oxygen control in ventilated infants born at or near term: A crossover trial.

AIM: To determine if the use of closed-loop automated oxygen control (CLAC) reduced the incidence and duration of hypoxemic episodes (SpO2  < 92%) in ventilated infants born at or above 34 weeks of gestation. METHODS: Infants were studied on two consecutive days for 6 h each day. They were randomised to receive standard care (manual oxygen control) or standard care with a CLAC system (automated oxygen control) first. RESULTS: Sixteen infants with a median (IQR) gestational age of 37.4 (36.6-38.8) weeks were studied at a median (IQR) postmenstrual age of 38.8 (37.4-39.8) weeks. During the automated oxygen control period, infants spent less time in hypoxemia (SpO2  < 92%) (p = 0.033), episodes of desaturation were shorter (p = 0.001), the time spent within target SpO2 range (92%-96%) was increased (p = 0.001), and the FiO2 delivery was lower (p = 0.018). The time spent in hyperoxemia (SpO2  > 96%) was reduced during automated oxygen control (p = 0.011), the episodes of hyperoxemia were of shorter duration (p = 0.008) and fewer manual adjustments were made to the FiO2 (p = 0.005). CONCLUSIONS: Closed-loop automated oxygen control in ventilated infants born at or near term was associated with a reduction in the incidence and duration of hypoxemic episodes with more time spent in the target oxygen range.

Comparing the safety and effectiveness of various umbilical cord milking techniques and delayed cord clamping in full-term and preterm infants: A systematic review and meta-analysis.

We compare the hematocrit, hemoglobin, need for transfusion, recurrent phototherapy, serum bilirubin level, and serum ferritin at different time frames for the umbilical cord milking (UCM) and delayed cord clamping (DCC) in both full-term and preterm infants. A comprehensive search through various databases aimed to compare UCM and DCC studies until May 2nd, 2023. Cochrane and NIH tools assessed RCTs and cohorts, respectively. Meta-analysis employed Review Manager 5.4 software, calculating MD and RR with 95% CIs for continuous and dichotomous data. We included 20 studies with a total of 5189 infants. Regarding preterm infants, hematocrit level showed no significant difference between intact Umbilical Cord Milking (iUCM) compared to DCC (MD = -0.24, 95% CI [-1.11, 0.64]). Moreover, Neonatal death incidence was significantly higher with the UCM technique in comparison to DCC (RR = 1.28, 95% CI [1.01 to 1.62]). Regarding term and late preterm infants, Hematocrit level showed no significant difference between the iUCM or cUCM techniques compared to DCC (MD = 0.21, 95% CI [-1.28 to 1.69]), (MD = 0.96, 95% CI [-1.02 to 2.95]), respectively. UCM led to a higher risk of neonatal death in preterm infants compared to DCC. However, the incidence of polycythemia was lower in the UCM group. Additionally, UCM was associated with higher rates of severe IVH events. Based on these findings, DCC may be preferred due to its lower incidence of severe IVH and neonatal death.

Nous comparons l'hématocrite, l'hémoglobine, le besoin de transfusion, la photothérapie récurrente, le taux de bilirubine sérique et la ferritine sérique à différentes périodes pour la traite du cordon ombilical (UCM) et le clampage retardé du cordon (DCC) chez les nourrissons nés à terme et prématurés. Une recherche complète dans diverses bases de données visait à comparer les études UCM et DCC jusqu'au 2 mai 2023. Les outils Cochrane et NIH ont évalué les ECR et les cohortes, respectivement. La méta-analyse a utilisé le logiciel Review Manager 5.4, calculant le MD et le RR avec des IC à 95 % pour les données continues et dichotomiques. Nous avons inclus 20 études portant sur un total de 5 189 nourrissons. Concernant les nourrissons prématurés, le niveau d'hématocrite n'a montré aucune différence significative entre la traite du cordon ombilical intact (iUCM) et la DCC (DM = -0,24, IC à 95 % [-1,11, 0,64]). De plus, l'incidence des décès néonatals était significativement plus élevée avec la technique UCM qu'avec la technique DCC (RR = 1,28, IC à 95 % [1,01 à 1,62]). Concernant les nourrissons à terme et peu prématurés, le niveau = 0,21, IC à 95 % [-1,28 à 1,69]), (DM = 0,96, IC à 95 % [-1,02 à 2,95]), respectivement. L'UCM a entraîné un risque plus élevé de décès néonatal chez les nourrissons prématurés par rapport au DCC. Cependant, l'incidence de la polyglobulie était plus faible dans le groupe UCM. De plus, l'UCM était associée à des taux plus élevés d'événements IVH graves. Sur la base de ces résultats, le DCC peut être préféré en raison de sa plus faible incidence d'IVH grave et de décès néonatals. d'hématocrite n'a montré aucune différence significative entre les techniques iUCM ou cUCM par rapport à la technique DCC (DM.

[Neuropsychological development of large for gestational age infants at the age of 12 months]. / 大于胎龄儿12æœˆé¾„ç¥žç»å¿ƒç†å‘è‚²çŠ¶å†µç ”ç©¶.

OBJECTIVES: To investigate the level of neuropsychological development in large for gestational age (LGA) infants at the age of 12 months. METHODS: The infants, aged 12 to <13 months, who attended the Outpatient Service of Child Care in the First Affiliated Hospital of Shandong First Medical University from December 2021 to June 2023, were enrolled as subjects. According to the gestational age and birth weight, they were divided into preterm appropriate for gestational age (AGA) group, preterm LGA group, early term AGA group, early term LGA group, full-term AGA group, and full-term LGA group. A modified Poisson regression analysis was used to investigate the association between LGA and neuropsychological development outcome at 12 months of age. RESULTS: After adjustment for confounding factors, compared with the full-term AGA group at the age of 12 months, the full-term LGA group had a significant increase in the risk of language deficit (RR=1.364, 95%CI: 1.063-1.750), the early term LGA group had significant increases in the risk of abnormal gross motor, fine motor, language, and the preterm LGA group had significant increases in the risk of abnormal language, social behavior, and total developmental quotient (P<0.05); also, the early term AGA group had higher risks of developmental delay across all five attributes and in total developmental quotient at the age of 12 months (P<0.05); except for the language attribute, the preterm AGA group had higher risks of developmental delay in the other 4 attributes (P<0.05). CONCLUSIONS: The neuropsychological development of LGA infants with different gestational ages lags behind that of full-term AGA infants at 12 months of age, and follow-up and early intervention of such infants should be taken seriously in clinical practice.

Can surfactants affect mortality and morbidity in term infants with respiratory failure?

BACKGROUND: We aimed to discuss term infants who are given surfactant due to respiratory disorder according to the underlying etiology, the dose of surfactant administration, and the need for repeated surfactant administration. METHODS: In this retrospective study infants hospitalized in the 4th level neonatal intensive care unit during January 2019 and December 2021 and administered surfactant due to respiratory distress were included. Term infants given surfactant due to respiratory failure were included in the study through the data recording system. The number of surfactant doses, indications for administration, mortality, duration of hospitalization, intubation time, and inotrope use were recorded in the infants included in the study. RESULTS: : During the two-year period, 1250 infants were hospitalized in our neonatal intensive care unit. Of those, 56 infants received surfactant replacement therapy for severe respiratory failure. There were 30 infants with pneumonia, 4 infants with meconium aspiration syndrome (MAS), and 22 infants with transient tachypnea of the newborn (TTN). It was seen that single-dose administration was higher in patients with TTN (p = 0.01), while multiple-dose surfactant administration was more common in patients with MAS, resulting in a statistical difference (p = 0.02). Mortality was lower, especially in cases given early surfactant administration and this situation was statistically significant (p < 0.001). Duration of intubation was 5.05 ± 4.7 days in early surfactant administration group and 8.0 ± 6.1 days in late surfactant administration group. This difference was statistically significant (p = 0.04). While early surfactant application was statistically higher in the TTN group (p = 0.007), late surfactant application was statistically higher in the pneumonia group (p = 0.001). DISCUSSION: Despite the difference on administration time and repeat dose interval due to etiology, surfactant treatment is improving the respiratory distress of term infants.

Role of umbilical cord C-peptide levels in early prediction of hypoglycemia in infants of diabetic mothers.

BACKGROUND: Until now, diabetes during pregnancy has been associated with a high risk of maternal, fetal, and neonatal morbidities and mortalities. The main aim of this study was to evaluate the risk factors of hypoglycemia in infants of diabetic mothers (IDMs) and to study the relationship between umbilical cord (UC) C peptide levels and the risk of developing hypoglycemia. MATERIAL AND METHODS: UC blood C-peptide and serial serum blood glucose measurements were done for all included singleton newborns born to diabetic mothers during the study period. Maternal and neonatal data such as gestational age, maternal age, maternal weight, types of diabetics and its control, maternal glycated hemoglobin (HbA1C), birth weight, Apgar score, and neonatal complete blood picture were collected. RESULTS: In total, 83 IDMs met the inclusion criteria. Fifty-four (65.06%) developed hypoglycemia and 29 (34.94%) remained normoglycemic. However, there were no significant differences between hypoglycemic and normoglycemic IDMs in terms of types of maternal diabetics (P value = 0.41), its duration (P value = 0.43). The hypoglycemia peak occurred within the first 3 h of life, with 33.11 ± 8.84 mg/dl for the hypoglycemia group and 54.10 ± 6.66 mg/dl for the normoglycemic group (P value < 0.0001). Most of the babies had no hypoglycemic manifestation (96.30%). Neonates with hypoglycemia their mothers had poor diabetes control in the last trimester (HbA1C 7.09 ± 0.96%) compared to normoglycemic babies (HbA1C 6.11 ± 0.38%), (P-value < 0.0001). The mean (SD) of UC C-peptide level in hypoglycemic neonates increased to 1.73 ± 1.07 ng/ml compared to normoglycemic ones with 1.08 ± 0.81 ng/ml (P value = 0.005). CONCLUSION: Poor diabetes control, especially in the last trimester, is associated with neonatal hypoglycemia. Increased UC C-peptide levels could be used as an early indicator for the risk of developing neonatal hypoglycemia and a predictor for babies need neonatal admission.

Adherence to Screening for Anemia in 9-Month-Old Full-Term Infants in Bangkok, Thailand.

OBJECTIVES: To determine adherence to the screening for anemia in 9-month-old full-term infants and factors associated with non-adherence to the screening for anemia. METHODS: A descriptive cross-sectional study was conducted in 9-month-old full-term healthy infants who visited the General Pediatric and Well Child Care Clinic, King Chulalongkorn Memorial Hospital, Bangkok, Thailand. Demographic data, adherence to the screening, and factors associated with non-adherence to the screening were analyzed using percentage, χ2 test, and bivariate logistic regression. RESULTS: A total of 234 full-term infants, aged 9 months, were included in the study between January and December 2019. The prevalence of adherence to the screening for anemia was 76.1% (95% CI 0.70-0.81). The most common cause of non-adherence to the screening was the waiting time for laboratory results (39.3%). Factors associated with non-adherence to the screening were low education of caregiver (AOR 2.684; 95% CI 1.451-4.966), low socio-economic status (AOR 2.26; 95% CI 1.568-3.258), and inadequate complementary food (AOR 1.961; 95% CI 1.107-3.473). CONCLUSION: The most common cause of non-adherence to the screening for anemia is the waiting time for laboratory results. Pediatricians and general practitioners should ensure the importance of anemia screening in infants and plan on anemia screening with parents.

Altered local cerebellar and brainstem development in preterm infants.

BACKGROUND: Premature birth is associated with high prevalence of neurodevelopmental impairments in surviving infants. The putative role of cerebellar and brainstem dysfunction remains poorly understood, particularly in the absence of overt structural injury. METHOD: We compared in-utero versus ex-utero global, regional and local cerebellar and brainstem development in healthy fetuses (n â€‹= â€‹38) and prematurely born infants without evidence of structural brain injury on conventional MRI studies (n â€‹= â€‹74) that were performed at two time points: the first corresponding to the third trimester, either in utero or ex utero in the early postnatal period following preterm birth (30-40 weeks of gestation; 38 control fetuses; 52 premature infants) and the second at term equivalent age (37-46 weeks; 38 control infants; 58 premature infants). We compared 1) volumetric growth of 7 regions in the cerebellum (left and right hemispheres, left and right dentate nuclei, and the anterior, neo, and posterior vermis); 2) volumetric growth of 3 brainstem regions (midbrain, pons, and medulla); and 3) shape development in the cerebellum and brainstem using spherical harmonic description between the two groups. RESULTS: Both premature and control groups showed regional cerebellar differences in growth rates, with the left and right cerebellar hemispheres showing faster growth compared to the vermis. In the brainstem, the pons grew faster than the midbrain and medulla in both prematurely born infants and controls. Using shape analyses, premature infants had smaller left and right cerebellar hemispheres but larger regional vermis and paravermis compared to in-utero control fetuses. For the brainstem, premature infants showed impaired growth of the superior surface of the midbrain, anterior surface of the pons, and inferior aspects of the medulla compared to the control fetuses. At term-equivalent age, premature infants had smaller cerebellar hemispheres bilaterally, extending to the superior aspect of the left cerebellar hemisphere, and larger anterior vermis and posteroinferior cerebellar lobes than healthy newborns. For the brainstem, large differences between premature infants and healthy newborns were found in the anterior surface of the pons. CONCLUSION: This study analyzed both volumetric growth and shape development of the cerebellum and brainstem in premature infants compared to healthy fetuses using longitudinal MRI measurements. The findings in the present study suggested that preterm birth may alter global, regional and local development of the cerebellum and brainstem even in the absence of structural brain injury evident on conventional MRI.

Midwife-to-newborn ratio and neonatal outcome in healthy term infants.

AIM: To assess the effect of midwife-to-infant ratio on healthy term infant outcome. METHODS: Infants were enrolled in an inhospital midwife-led centre and an obstetrician-led centre with different midwife-to-infant ratios (1:2.5-1:5 vs 1:7-1:15). The primary endpoint was exclusive breastfeeding rate; secondary endpoints were neonatal admission in neonatal care unit rate and length of hospital stay. RESULTS: One hundred and ten infants were enrolled in both midwife- and obstetrician-led centre. Exclusive breastfeeding rate at discharge was higher (88% vs 78%, P = .048) in infants born in the midwife- than in the obstetrician-led centre. Admission rate in neonatal care units (9% vs 2%, P = .017) and stay in hospital duration (3.1 ± 1.8 vs 2.6 ± 0.8 days, P = .008) were higher in the obstetrician- than in the midwife-led centre. Birth in the midwife-led centre increased the likelihood of exclusive breastfeeding (OR: 2.04, 1.07-3.92), while newborns' admission in neonatal care units decreased it (OR : 0.17, 0.07-0.43). CONCLUSION: Healthy term infants' neonatal outcome is negatively associated with a low midwife-to-infant ratio which decreases exclusive breastfeeding rate and is associated with a higher likelihood of admission in neonatal care units and longer stay in hospital.

Motor trajectories of preterm and full-term infants in the first year of life.

BACKGROUND: Motor development occurs throughout periods of motor skill acquisition, adjustment and variability. The objectives of this study were to analyze and compare biological and health characteristics and motor skill acquisition trajectories in preterm and full-term infants during the first year of life. METHODS: Two thousand, five hundred and seventy-nine infants (1,361 preterm) from 22 states were assessed using the Alberta Infant Motor Scale. Multivariate General Linear Model, t-tests, ANOVA, and Tukey tests were used. RESULTS: An age × group significant interaction was found for motor scores. On follow-up tests full-term infants had higher scores in prone, supine, sitting and standing postures that require trunk control from 9 to 10 months of age; although this advantage was observed for sitting from the second month of life. CONCLUSION: During the first trimester of life, preterm infants have higher scores in the supine and standing postures. Regarding motor trajectories, from newborn to 12 months, the period of higher motor acquisition was similar between full-term and preterm infants for prone (3-10 months), supine (1-6 months), and standing (6-12 months). For the sitting posture, however, full-term infants had a period of intensive motor learning of acquisition from the first to 7 months of life, whereas for preterm infants a shorter period was observed (3-7 months). CONCLUSION: Although the periods of higher motor acquisition were similar, full-term infants had higher scores in more control-demanding postures. Intervention for preterm infants needs to extend beyond the first months of life, and include guidance to parents to promote motor development strategies to achieve control in the higher postures.

Prevalence and characteristics of positional plagiocephaly in healthy full-term infants at 8-12 weeks of life.

Positional plagiocephaly (PP) denotes flattening of the skull that occurs frequently in healthy infants. Aim of this study was to estimate the prevalence of positional plagiocephaly and to identify the risk factors in a cohort of healthy infants in order to help prevention of PP. In a prospective design, all healthy full-term infants, ranging from 8 to 12 weeks of age, who presented at the public immunization clinic in Ferrara, were eligible for the study. After obtaining informed consent, we interviewed the parents and examined the infants using the Argenta's assessment tool. Of 283 infants examined, 107 (37.8%) were found to have PP at 8-12 weeks of age. In 64.5%, PP was on the right side, 50.5% were male and 15% presented also with brachycephaly. Risk factors significantly associated were lower head circumference, advanced maternal age, Italian compared to African, and supine sleep position, in particular for infants born at 37 weeks, preference for one side of the head. In logistic regression, risk factors significantly associated were lower birth weight, advanced maternal age, and supine sleep position. CONCLUSIONS: Positional plagiocephaly is a common issue faced by pediatricians; our results reinforce the need of improving prevention both of sudden infant death and positional plagiocephaly, through uniform messages provided prenatally and postnatally by different health professionals. "What is Known:" •The incidence of positional plagiocephaly varies due to population studied and measuring methods. •Different factors are considered in the literature as being associated to positional plagiocephaly (infant factors, obstetric factors, infant care practices, sociodemographic factors). "What is New:" •This is one of the few European studies quantifying positional plagiocephaly prevalence in a population of unselected healthy infants. •In this study, positional plagiocephaly is confirmed as a common issue, related to some factor (as supine sleep position and positional head prevalence) that should be addressed in pre and postnatal counseling. •The prone sleepers rate in our population highlight the need to improve parental awareness regarding SIDS prevention, in particular in borderline gestational age.

The analysis of posterior segment findings in term and premature infants using RetCam images.

OBJECTIVE: To analyze posterior segment findings in term and premature infants using the RetCam image database. METHODS: RetCam images taken of infants born between January 2012 and December 2015 were reviewed. Group 1 included infants with posterior segment findings other than retinopathy of prematurity (ROP). Group 2 included infants with mild-to-severe ROP. The baseline characteristics, anterior segment findings, and percentage of infants who received treatment were compared among the 2 groups. RESULTS: In total, 331 out of 3440 infants (9.6%) were included. The major diagnoses in group 1 (n = 75) were retinal hemorrhages in 26, optic nerve pathologies in 14, findings associated with a metabolic disease in 6, ocular tumors in 5, persistent hyperplastic primary vitreous in 4, and familial exudative vitreoretinopathy in 4 cases. The mean birth weight (g) (2481.9 ± 700.5 in group 1 vs 1090.5 ± 330.9 in group 2), gestational age (weeks) (35.9 ± 3.4 in group 1 vs 28.2 ± 2.4 in group 2), and postmenstrual age at initial examination (35.9 ± 3.4 in group 1 vs 28.2 ± 2.4 in group 2) were significantly different among the 2 groups (p < 0.001). Thirteen out of 75 cases in group 1 and 124 out of 256 ROP cases received therapy (p < 0.001). Anterior segment pathologies were found in 13.3% of group 1 versus 7.8% of group 2 infants (p = 0.216). CONCLUSIONS: A considerable number of infants suffered from posterior segment disorders other than ROP. The majority of these infants were term babies. Routine fundus screening may be recommended in all newborns to diagnose all posterior segment pathologies other than ROP.

Measurement of brain tissue oxygen saturation in term infants using a new portable near-infrared spectroscopy device.

BACKGROUND: A small oximeter with the probe attached to the examiner's finger has been developed. The aim of this study was to determine the feasibility of measuring regional oxygenation of the brain tissue using this device in healthy term infants immediately after birth. METHODS: We conducted a prospective observational study. Using a new near-infrared spectroscopy (NIRS) device, we measured changes in regional cerebral tissue oxygen saturation (crSO2 ) during the first 10 min of life in 32 healthy term infants after delivery. Arterial oxygen saturation (SpO2 ) was also simultaneously measured. RESULTS: Median crSO2 increased from 43% (1 min after birth) to 49% (4 min after birth); thereafter, no significant changes were observed. Median SpO2 increased constantly from min 3 to min 7, from 77% to 92% and did not change significantly after 8 min. A stable oxygen saturation signal was measured in 59% of infants (crSO2 ) and in 0% of infants (SpO2 ) at 1 min, and in 97% (crSO2 ) and in 78% (SpO2 ) at 3 min. CONCLUSIONS: During the transition after birth, crSO2 can be more easily and quickly measured in healthy newborn infants using the novel NIRS device than SpO2 .

Determination of Normal Anal Position Index Using a Modified Technique in Turkish Neonates.

AIM: This study was aimed to determine the normal position of the anus using the anal position index (API) in an attempt to develop a more sensitive method for measuring API. To investigate API in a wide range of neonates, both term and preterm infants were included in the present study. MATERIALS AND METHODS: API was determined by measuring the anus-fourchette (FA) and anus-coccyx (AC) distance in female neonates and the anus-scrotum and AC distance in male neonates. API is defined as the ratio of the FA (scrotum) distance to the AC distance. A digital caliper was used for all measurements. The FA or scrotum and coccyx-fourchette or -scrotum distances were measured using digital calipers. RESULTS: A total of 267 neonates (females, 143; males 124) were included in this study. Of these, 36 were borderline premature infants (birth at 35-37 weeks gestation) and 231 were term infants (birth at 38-42 weeks gestation). The mean API was 1.06 ± 0.04 in female and 0.90 ± 0.08 in male neonates. When premature infants were analyzed separately, the mean API was 1.12 ± 0.08 in female and 0.99 ± 0.09 in male neonates. No significant difference in API values was observed between term and preterm neonates (P < 0.05). CONCLUSIONS: API values that differ from the previous studies were identified in the present study. We believe our modified method allows for more accurate measurements of the API in newborns. According to our method, the anus should be considered as anteriorly located if API is <1 in female and < 0.9 in male neonates. In addition, the present study is the first to measure API using digital calipers. Digital calipers were found to be convenient and are useful in determining the API with high accuracy (to within 0.01 cm).

Risk Factors for Neonatal Arterial Ischemic Stroke: The Importance of the Intrapartum Period.

OBJECTIVE: To investigate risk factors for neonatal arterial ischemic stroke (NAIS), and compare them with those present in term controls and infants with hypoxic-ischemic encephalopathy (HIE). STUDY DESIGN: Antepartum and intrapartum data were collected at presentation from 79 infants with NAIS and compared with 239 controls and 405 infants with HIE. The relationships between risk factors and NAIS were explored using univariable and multivariable regression. RESULTS: Compared with controls, infants with NAIS more frequently had a family history of seizures/neurologic diseases, primiparous mothers, and male sex. Mothers of infants with NAIS experienced more intrapartum complications: prolonged rupture of membranes (21% vs 2%), fever (14% vs 3%), thick meconium (25% vs 7%), prolonged second stage (31% vs 13%), tight nuchal cord (15% vs 6%), and abnorm8al cardiotocography (67% vs 21%). Male sex (OR 2.8), family history of seizures (OR 6.5) or neurologic diseases (OR 4.9), and ≥1 (OR 5.8) and ≥2 (OR 21.8) intrapartum complications were independently associated with NAIS. Infants with NAIS and HIE experienced similar rates though different patterns of intrapartum complications. Maternal fever, prolonged rupture of membranes, prolonged second stage, tight nuchal cord, and failed ventouse delivery were more common in NAIS; thick meconium, sentinel events, and shoulder dystocia were more frequent in HIE. Abnormal cardiotocography occurred in 67% of NAIS and 77.5% of infants with HIE. One infant with NAIS and no infant with HIE was delivered by elective cesarean (10% of controls). CONCLUSIONS: NAIS is multifactorial in origin and shares risk factors in common with HIE. Intrapartum events may play a more significant role in the pathogenesis of NAIS than previously recognized.
