The effect of perceived social support on fatigue in mothers having twin infants: the mediating role of sleep quality.

The aim of this study is to investigate the mediating role of sleep quality in the relationship between multidimensional perceived social support and fatigue among mothers of twin infants. One hundred and six (106) twin mothers participated in this cross-sectional study, who completed the Descriptive Information Form, Multidimensional Scale of Perceived Social Support, Pittsburgh Sleep Quality Index, and Checklist Individual Strength. The scale score averages of the mothers in the study are as follows: social support, 61.41 ± 23.86; fatigue, 77.64 ± 28.68; and sleep quality, 8.26 ± 2.38. According to the path model, perceived social support has a negative effect on poor sleep quality (p = .001, Beta = -0.411), and poor sleep quality has a positive effect on fatigue (p = .001, Beta = 0.335). Sleep quality also mediates the effect of multidimensional perceived social support on mothers' fatigue levels (p = .001, Beta = -0.138). The study results suggest that the perceived social support and fatigue levels of twin mothers are moderate, while their sleep quality is poor. Therefore, mothers of twin infants may benefit from increased social support to alleviate fatigue and enhance sleep quality.

[Effect of prenatal glucocorticoid therapy on hearing screening in premature infants].

Objective:To explore the effect of prenatal glucocorticoids therapy on hearing screening in premature infants Methods:Data of 693 preterm infants with gestational age of 24-34+6weeks admitted to theJiangxi Maternal and Child Health Hospital within 24 h after birth from June 2022 to June 2023 were retrospectively analyzed. The infants were divided into the DXM group （544 cases） and the non-DXM group （149 cases） based on whether dexamethasone （DXM） was administered prenatally. General data of preterm infants and parturients in two groups were compared, and the effects of different doses and timing of DXM on hearing screening were analyzed. Results:In the terms of preliminary hearing screening. the pass rate of initial hearing screening in DXM group was significantly higher than that in non-DXM group（53.9% vs 35.6%）, with statistical significance（P<0.05）. Further subgroup analysis showed that the passing rate of preliminary hearing screening in adequate prenatal dose（=4 doses） DXM group（58.1%） was significantly higher than that in insufficient group（48.0%） and excessive group（42.4%）, with statistical significance（P<0.05）. Administering DXM 48 hours to 7 days before birth resulted in a higher pass rate for initial hearing screening compared to administration <48 hours or >7 days before birth （56.4% vs. 48.6%）, with a statistically significant difference （P < 0.05）. In terms of re-hearing screening, the pass rate of secondary hearing screening was not significantly correlated with DXM treatment（P>0.05）, but was significantly correlated with gestational age, birth weight, hospital stays, invasive mechanical ventilation, and common neonatal diseases（bronchopulmonary dysplasia, respiratory distress syndrome）（P<0.05）. Among them, bronchopulmonary dysplasia was an independent risk factor forsecondary hearing screening referral（P<0.05）. Conclusion:A single course of adequate dexamethasone use within 48 h-7 d of prenatal has a positive effect on the preliminary hearing screening of preterm infants.

Enhancing discharge preparation for parents after complex cardiac surgery: evaluation of an e-learning resource for nurses.

Parents need to be appropriately prepared by knowledgeable healthcare professionals before going home with their infant following cardiac surgery for complex congenital heart disease (CHD). A quality improvement project was undertaken between 2018 and 2021 to equip healthcare professionals including children's cardiac nurses with the knowledge required to use the Congenital Heart Assessment Tool (CHAT) to teach parents how to monitor their infant at home. The project involved developing, implementing and evaluating an e-learning resource that included simulated scenarios captured on video. An online survey showed that users perceived the e-learning resource as having a positive effect on their understanding of complex CHD and their practice of preparing parents for discharge and home monitoring.

Mid-childhood autism sibling recurrence in infants with a family history of autism.

Autism sibling recurrence in prospective infant family history studies is ~20% at 3 years but systematic follow-up to mid-childhood is rare. In population and clinical cohorts autism is not recognized in some children until school-age or later. One hundred and fifty-nine infants with an older sibling with autism underwent research diagnostic assessments at 3 years and mid-childhood (6 to 12 years (mean 9)). We report the autism sibling recurrence rate in mid-childhood and compare developmental and behavioral profiles at mid-childhood and 3 years in those with earlier versus later recognized autism, and those who had, or had not, received a community autism diagnosis. The autism recurrence rate in this sample in mid-childhood was 37.1%, 95% CI [29.9%, 44.9%] and higher in boys than girls. Around half of those diagnosed with autism in mid-childhood had not received a diagnosis at 3 years. Later, diagnosis was more common in girls than boys. While some had sub-threshold symptoms at 3, in others late diagnosis followed a largely typical early presentation. Sibling recurrence based on community clinical diagnosis was 24.5%, 95% CI [18.4%, 31.9%]. Those who also had a community diagnosis tended to be older, have lower adaptive function and higher autism and inattention symptoms. Notwithstanding limitations of a single site study, modest sample size and limits to generalisability, autism sibling recurrence in family history infants may be higher in mid-childhood than in studies reporting diagnostic outcome at 3 years. Findings have implications for families and clinical services, and for prospective family history studies.

A Single-Subject Study to Consider the Premature Infant Oral Motor Intervention Combined with Kinesio-Tape in Premature Infants with Feeding Problems.

Background: The survival rate in premature infants (PIs) has increased, but many have medical and developmental complications. Difficulty with sucking, swallowing, and poor nourishment are common complications. This study aimed to investigate the effects of Kinesio-tape (KT) combined with premature infant oromotor intervention (PIOMI) on feeding efficiency (mean volume intake [%MV]), oromotor skills (Preterm Oral Feeding Readiness Assessment Scale [POFRAS]), and weight gain in PIs. Methods: In this single-subject study, 5 PIs with feeding problems were received the PIOMI-KT for 7 consecutive days. The main outcome measure was the POFRAS scale. The %MV and weight gain were the secondary outcome measures. Measurements were taken before treatment (T0), after the 4th session (T1), and after the 7th session (T3). Results: The POFRAS scores, %MV, and weight gain improved in all infants after treatment. The maximum and minimum change in level between the baseline and treatment phase was +26 and+16 for POFRAS, +54 and, +34 for %MV, +180, and +100 for weight gain. The treatment trend was upward for all infants and shown by the directions of the slopes indicated by positive values. The feeding problems were resolved in all infants after the 7th treatment session. Conclusion: The combination therapy of PIOMI-KT improved feeding function in PIs.

Infants show systematic rhythmic motor responses while listening to rhythmic speech.

Rhythm is known to play an important role in infant language acquisition, but few infant language development studies have considered that rhythm is multimodal and shows strong connections between speech and the body. Based on the observation that infants sometimes show rhythmic motor responses when listening to auditory rhythms, the present study asked whether specific rhythm cues (pitch, intensity, or duration) would systematically increase infants' spontaneous rhythmic body movement, and whether their rhythmic movements would be associated with their speech processing abilities. We used pre-existing experimental and video data of 148 German-learning 7.5- and 9.5-month-old infants tested on their use of rhythm as a cue for speech segmentation. The infants were familiarized with an artificial language featuring syllables alternating in pitch, intensity, duration, or none of these cues. Subsequently, they were tested on their recognition of bisyllables based on perceived rhythm. We annotated infants' rhythmic movements in the videos, analyzed whether the rhythmic moving durations depended on the perceived rhythmic cue, and correlated them with the speech segmentation performance. The result was that infants' motor engagement was highest when they heard a duration-based speech rhythm. Moreover, we found an association of the quantity of infants' rhythmic motor responses and speech segmentation. However, contrary to the predictions, infants who exhibited fewer rhythmic movements showed a more mature performance in speech segmentation. In sum, the present study provides initial exploratory evidence that infants' spontaneous rhythmic body movements while listening to rhythmic speech are systematic, and may be linked with their language processing. Moreover, the results highlight the need for considering infants' spontaneous rhythmic body movements as a source of individual differences in infant auditory and speech perception.

Ultra-high-frequency ultrasound (48-70 MHz) is a promising tool for improved gastrointestinal diagnostics in infants.

AIM: To investigate the clinical feasibility of ultra-high-frequency abdominal ultrasound (UHFUS) scans of preterm and term infants. METHODS: Prospectively, 19 healthy term newborn infants were examined with conventional ultrasound (CUS) (Toshiba, Aplio i700, linear probe 14L5) and UHFUS (Visualsonics VevoMD, linear probes UHF48 and UHF70) according to a standardised protocol. Measurements of wall thickness were performed for; stomach, small intestine, colon and peritoneum. Five preterm infants, with or without suspected necrotising enterocolitis (NEC), were also examined with UHF48. Of these, only one was later diagnosed with NEC. RESULTS: Differences between CUS and UHFUS (UHF48) were found in measurements of thickness; for peritoneum 0.25 versus 0.13 mm (p < 0.001), small intestine 0.76 versus 0.64 mm (p = 0.039) and colon 0.7 versus 0.47 mm (p < 0.001) in healthy term infants. Gaining frequency from 46 to 71 MHz showed a mean reduction in measurements of peritoneum from 0.13 to 0.09 mm (p < 0.001). One preterm infant with NEC showed a fivefold and twofold increase in peritoneal and gastrointestinal wall thickness respectively, compared to healthy preterm infants. CONCLUSION: UHFUS was a clinically feasible, promising method with potential to improve gastrointestinal diagnostics in infants. Lower peritoneum thickness and gastrointestinal wall thickness were demonstrated with UHFUS compared to CUS, suggesting an overestimation by CUS.

Development of Movement and Postural Patterns in Full-Term Infants Who Are at Low Risk in Belgium, India, Norway, and the United States.

OBJECTIVE: The objective of this study was to investigate the influences on motor development in infants who are at low risk from Belgium, India, Norway, and the United States (US) using the General Movement Assessment (GMA) at 10-16 weeks post-term age. METHODS: This was a cross-sectional study of prospectively enrolled full-term infants at low risk (n = 186). Certified GMA observers rated the fidgety movements, quality of the movement patterns, age-adequacy of the movement repertoire, postural patterns, movement character, and overall Motor Optimality Score - Revised (MOS-R). Scores were evaluated for associations with sex, birth weight category, gestational age, post-term age at video, and country. RESULTS: The majority of infants had normal fidgety movements (179/186, 96.2%). This did not vary by sex, birth weight, gestational age, post-term age at video, or country. All infants showed normal>atypical movement patterns. Variability was seen for age adequacy (optimal: 137/183, 74.9%), postural patterns (normal>atypical: 164/183, 89.6%), and smooth/ fluent movement character (138/183, 75.4%). Gestational age and post-term age at video were associated with atypical postural patterns but in multivariable regression, only younger post-term age retained significance (OR 2.94, 95% CI: 1.05-8.24). Lack of age adequacy was associated with post-term age (OR 13.15, 95% CI: 4.36-39.72), and country (compared with Norway; Belgium OR 3.38 95% CI:12.4-9.22; India OR 3.16, 95% CI:1.01-9.87: US not significant). Infants from India also showed lower rates of an optimal MOS-R (25-28) than infants from Norway. CONCLUSIONS: The normality and temporal organization of fidgety movements did not differ by sex, birth weight, post-term age, or country, suggesting that the fidgety movements are free of cultural and environmental influences. The majority of full-term infants who were healthy in this cohort showed normal scores for all aspects of motor development tested using the MOS-R. Differences in age adequacy and MOS-R by country warrant investigation with larger cohorts and longitudinal follow up. IMPACT STATEMENT: Understanding variations in typical motor development is essential to interpreting patterns of movement and posture in infants at risk for atypical development. Using the framework of Prechtl's General Movements Assessment, this study showed that the development of movement and posture in healthy infants were affected by age and country of birth, but the development of the fidgety movements appeared to be free of these influences. Local norms may be needed to interpret the Motor Optimality Score-Revised in all populations but further research on this topic is needed.

Cord Obstruction and Delayed Cord Clamping Do Not Affect Gut Function in Neonatal Piglets.

INTRODUCTION: Birth-related obstruction of umbilical blood flow may induce hypoxic insults that affect postnatal organ adaptation. Using newborn cesarean-delivered pigs, we hypothesized that cord obstruction during delivery negatively affects physiological transition and gut maturation. Further, we investigated if delayed cord clamping (DCC) improves gut outcomes, including sensitivity to formula-induced necrotizing enterocolitis (NEC)-like lesions. METHODS: In experiment 1, preterm (n = 24) and near-term (n = 29) piglets were subjected to umbilical cord obstruction (UCO, 5-7 min in utero), with corresponding pigs delivered without obstruction (CON, n = 17-22). Experiment 2 assessed preterm pigs subjected to delayed cord clamping (n = 30, 60 s) or immediate cord transection with umbilical cord milking (UCM, n = 34). Postnatal vital parameters were recorded, together with a series of gut parameters after 3 days of formula feeding. RESULTS: UCO induced respiratory-metabolic acidosis in near-term pigs at birth (pH 7.16 vs. 7.32, pCO2 12.5 vs. 9.2 kPa, lactate 5.2 vs. 2.5 mmol/L, p < 0.05). In preterm pigs, UCO increased failure of resuscitation and mortality shortly after birth (88 vs. 47%, p < 0.05). UCO did not affect gut permeability, transit time, macromolecule absorption, six digestive enzymes, or sensitivity to NEC-like lesions. In experiment 2, DCC improved neonatal hemodynamics (pH 7.28 vs. 7.20, pCO2 8.9 vs. 9.9 at 2 h, p < 0.05), with no effects on gut parameters. CONCLUSION: UCO and DCC affect neonatal transition and hemodynamics, but not neonatal gut adaptation or sensitivity to NEC-like lesions. Our findings suggest that the immature newborn gut is highly resilient to transient birth-related changes in cord blood flow.

Oxygen saturation and work of breathing indices in preterm infants with bronchopulmonary dysplasia compared to healthy preterm infants at discharge.

BACKGROUND: Thoracoabdominal asynchrony (TAA) is commonly seen in preterm infants. Respiratory inductive plethysmography (RIP) is a noninvasive way to objectively assess work of breathing (WOB) indices. The impact of bronchopulmonary dysplasia (BPD) on TAA at discharge has not been established. The aim of this study is to compare WOB indices in premature infants with a diagnosis of BPD to premature infants without a diagnosis of BPD at discharge. METHODS: A prospective, observational study of premature infants (<32 weeks gestation) at discharge during quiet breathing in the supine position. RIP noninvasively measured WOB indices. A high-resolution pulse oximeter collected oxygen saturation and heart rate data. RESULTS: This study included thirty-one infants with BPD and thirty-four infants without BPD. Infants diagnosed with BPD had increased phase angle [BPD Φ = 73 . 90 (8.2) vs NoBPD Φ = 52.6 (8.2), p = 0.039]. Infants diagnosed with BPD had decreased saturations [BPD SpO2 = 96% (0.4) vs NoBPD Sp02 98% (0.3), p=<0.001], increased time with saturations less than 85% [BPD % =2.74 (0.7) vs NoBPD % =0.91 (0.4), p = .018], and increased time with saturations less than 80% [BPD % =1.57 (0.5) vs NoBPD % =0.52 (0.3), p = 0.045]. There was no difference in heart rate or breaths per minute for infants with BPD versus controls. CONCLUSION: Premature infants with BPD demonstrated increased TAA and had lower saturations compared to infants without BPD at discharge despite being chronologically older and being discharged at an older corrected gestational age. The impact of BPD on breathing patterns persists at discharge and suggests these patients may have residual lung and/or respiratory muscle dysfunction.

Doctor-Parent Disagreement for Preterm Infants Born in the Grey Zone: Do Ethical Frameworks Help?

OBJECTIVE: To examine i) how ethical frameworks can be used in concrete cases of parent-doctors' disagreements for extremely preterm infants born in the grey zone to guide such difficult decision-making; and ii) what challenges stakeholders may encounter in using these frameworks. DESIGN: We did a case analysis of a concrete case of parent-doctor disagreement in the grey zone using two ethical frameworks: the best interest standard and the zone of parental discretion. RESULTS: Both ethical frameworks entailed similar advantages and challenges. They have the potential 1) to facilitate decision-making because they follow a structured method; 2) to clarify the situation because all relevant ethical issues are explored; and 3) to facilitate reaching an agreement because all parties can explain their views. We identified three main challenges. First, how to objectively evaluate the risk of severe disability. Second, parents' interests should be considered but it is not clear to what extent. Third, this is a value-laden situation and different people have different values, meaning that the frameworks are at least partially subjective. CONCLUSIONS: These challenges do not mean that the ethical frameworks are faulty; rather, they reflect the complexity and the sensitivity of cases in the grey zone.

Retrospective analysis of reference intervals for dried blood spot based ms/ms newborn screening programs in Chinese preterm neonates: a nationwide study.

OBJECTIVES: Although recent discoveries regarding the biomarkers of newborn screening (NBS) programs by tandem mass spectrometry (MS/MS) highlight the critical need to establish reference intervals (RIs) specifically for preterm infants, no such RIs has been formally published yet. This study addressed the gap by offering a comprehensive set of reference intervals (RIs) for preterm neonates, and illustrating the dynamic changes of each biomarker with age. DESIGN AND METHODS: The NBS data of 199,693 preterm newborns (< 37 weeks of gestation) who met the inclusion and exclusion criteria from the NNSCP database were included in study analysis. The birth weight stratified dynamic trend of each biomarker were captured by their concentrations over age. Reference partitions were determined by the method of Harris and Boyd. RIs, corresponding to the 2.5th and 97.5th percentiles, as well as the 0.5th, 25th, 50th, 75th and 99.5th percentiles were calculated using a non-parametric rank approach. RESULTS: Increasing birth weight is associated with an elevation in the levels of arginine, citrulline, glycine, leucine and isobarics, methionine, ornithine, phenylalanine, and valine, whereas the levels of alanine, proline and tyrosine decrease. Additionally, two short-chain acylcarnitines (butyrylcarnitine + isobutyrylcarnitine and isovalerylcarnitine + methylbutyrylcarnitine) and a median-chain acylcarnitine (octenoylcarnitine) decrease, while four long-chain acylcarnitines (tetradecanoylcarnitine, palmitoylcarnitine, palmitoleylcarnitine and oleoylcarnitine) increase with increasing birth weight. Age impacts the levels of all MS/MS NBS biomarkers, while sex only affects the level of malonylcarnitine + 3-hydroxybutyrylcarnitine (C3-DC + C4-OH) in very low birth weight preterm neonates. CONCLUSION: The current study developed reference intervals (RIs) specific to birth weight, age, and/or sex for 35 MS/MS biomarkers, which can help in the timely evaluation of the health and disease of preterm neonates.

Comparison of "IN-REC-SUR-E" and LISA in preterm neonates with respiratory distress syndrome: a randomized controlled trial (IN-REC-LISA trial).

BACKGROUND: Surfactant is a well-established therapy for preterm neonates affected by respiratory distress syndrome (RDS). The goals of different methods of surfactant administration are to reduce the duration of mechanical ventilation and the severity of bronchopulmonary dysplasia (BPD); however, the optimal administration method remains unknown. This study compares the effectiveness of the INtubate-RECruit-SURfactant-Extubate (IN-REC-SUR-E) technique with the less-invasive surfactant administration (LISA) technique, in increasing BPD-free survival of preterm infants. This is an international unblinded multicenter randomized controlled study in which preterm infants will be randomized into two groups to receive IN-REC-SUR-E or LISA surfactant administration. METHODS: In this study, 382 infants born at 24+0-27+6 weeks' gestation, not intubated in the delivery room and failing nasal continuous positive airway pressure (nCPAP) or nasal intermittent positive pressure ventilation (NIPPV) during the first 24 h of life, will be randomized 1:1 to receive IN-REC-SUR-E or LISA surfactant administration. The primary outcome is a composite outcome of death or BPD at 36 weeks' postmenstrual age. The secondary outcomes are BPD at 36 weeks' postmenstrual age; death; pulse oximetry/fraction of inspired oxygen; severe intraventricular hemorrhage; pneumothorax; duration of respiratory support and oxygen therapy; pulmonary hemorrhage; patent ductus arteriosus undergoing treatment; percentage of infants receiving more doses of surfactant; periventricular leukomalacia, severe retinopathy of prematurity, necrotizing enterocolitis, sepsis; total in-hospital stay; systemic postnatal steroids; neurodevelopmental outcomes; and respiratory function testing at 24 months of age. Randomization will be centrally provided using both stratification and permuted blocks with random block sizes and block order. Stratification factors will include center and gestational age (24+0 to 25+6 weeks or 26+0 to 27+6 weeks). Analyses will be conducted in both intention-to-treat and per-protocol populations, utilizing a log-binomial regression model that corrects for stratification factors to estimate the adjusted relative risk (RR). DISCUSSION: This trial is designed to provide robust data on the best method of surfactant administration in spontaneously breathing preterm infants born at 24+0-27+6 weeks' gestation affected by RDS and failing nCPAP or NIPPV during the first 24 h of life, comparing IN-REC-SUR-E to LISA technique, in increasing BPD-free survival at 36 weeks' postmenstrual age of life. TRIAL REGISTRATION: ClinicalTrials.gov NCT05711966. Registered on February 3, 2023.

Instructional guidelines and group discussion effects on new nurses' competency regarding nursing care of preterm infants.

Background: Premature birth was once one of the leading causes of infant mortality. Premature infants require improved medical and nursing skills from a highly competent nursing team. Purpose: This investigation aimed to assess the effects of instructional guidelines and group discussion on new nurses' competency in preterm infants caring at the Neonatal Intensive Care Unit (NICU). Methods: A single-anonymized, two-group pre-test and post-test study design was accompanied in 2022. The study was accompanied for 50 newly graduated nurses concerned with competence in nursing management of preterm infants at the Neonatal Intensive Care Unit (NICU) in two hospitals: Al-Namas General Hospital, KSA, and the Pediatric Hospital of Assiut University, Egypt. Two groups were randomly selected from among the nurses to be trained on preterm infant nursing care competence either through an instructional guideline or group discussion. Nursing attitudes and practices were measured before and after training using questionnaires and checklists. Results: There was no significant difference between the instructional guideline group and the group discussion in the mean total score of attitudes (11.72 and 14.65, P = 0.455) and practices (14.36 and 14.80, P = 0.494) towards caring for preterm infants before intervention. While mean nurses' attitude and practice scores increased significantly in both groups after the intervention, in the discussion group, nurses' practice scores increased significantly (p = 0.001). Still, there were no significant changes in the instructional guideline group (P = 0.202). Conclusion: Both methods were effective on the newly graduated nurses' attitude; however, the instructional guidelines did not affect their practice regard nursing care of preterm infants. However, group discussion training techniques can effectively improve the nurses' attitude and practice toward nursing care of preterm infants. Relevance to clinical practice: The group discussion training method should be the approved and proven method for hospitals to train new nurses to increase clinical practices, especially during nursing care for premature infants, because this method has proven its worth in increasing the skill of nurses. It enables a group to talk about a specific subject and exchange personal stories. This approach involves a group leader facilitating communication and interaction between participants.

Teaching an Infant to Request Help.

Teaching an infant manual signs is beneficial as it promotes early communication, improves socialization, and can functionally replace behaviors such as crying and whining. Improving early communication also may reduce the probability of an infant engaging in dangerous behavior, like unsafe climbing. The purpose of this study was to extend Thompson et al. (Journal of Applied Behavior Analysis 40:15-23, 2007) by teaching an 8-month-old infant, who was noted to display developmental delays, to sign for "help" when preferred items were inaccessible. Similar to Thompson et al., delayed prompting and differential reinforcement was efficacious in teaching the infant to sign for "help," and the skill generalized to situations that were previously associated with unsafe climbing. However, undesirable generalization of signs for "help" when the infant could independently access the items was observed. Additional teaching was necessary to ensure signing for "help" occurred under appropriate antecedent control.

Development of a culturally enhanced caregiver-facilitated language nutrition intervention "+Language is Medicine" to address developmental delay in Diné (Navajo) toddlers.

Introduction: Developmental Delay (DD) is highly common in American Indian and Alaska Native (AI/AN; Indigenous) toddlers and leads to high numbers of AI/AN children who eventually need special education services. AI/AN children are 2.89 times more likely to receive special education compared to other children in the U.S., yet developmental disorders are more frequently under diagnosed and untreated in AI/AN infants and toddlers. DD, which can be identified as early as toddlerhood, can lead to negative impacts on developmental trajectories, school readiness, and long-term health. Signs of DD can be identified early with proper developmental screening and remediated with high quality early intervention that includes effective parent training. There are many evidence-based language facilitation interventions often used in Early Intervention programs. However, in communities in rural parts of the Navajo Nation where there are limited services and resources, infants and toddlers with early signs of DD are often missed and do not get the culturally responsive support and evidence-based intervention they deserve. Methods: The community-based +Language is Medicine (+LiM) study team partnered with tribal home visitors, community members, and a Diné linguist/elder using a collaborative virtual workgroup approach in 2021 and 2022 to present the +LiM pilot study aims and to discuss strategies for enhancing a language intervention for toddlers experiencing DD in their tribal community. This paper will detail the stages of community engagement, intervention enhancement and preparation for field testing of the +LiM intervention to address elevated rates of DD in toddlers in the Northern Agency of the Navajo Nation. Results: Two major outcomes from this collaborative workgroup included: (1) a team-initiated redefining of language nutrition to align with Indigenous values that center cultural connectedness and native language use and (2) a five-lesson caregiver-facilitated curriculum titled +Language is Medicine which includes caregiver lessons on language nutrition, language facilitation, shared book reading, pretend play, and incorporation of native language into home routines. These two workgroup outcomes were leveraged to develop a pilot pre-/post-intervention study to test the effectiveness of the +LiM intervention with caregiver-toddler dyads living on the Navajo Nation. Discussion: Delivering tailored child interventions through tribal home visiting are cost-effective and innovative methods for reaching reservation-based families who benefit from culturally responsive parent coaching and instruction. The +LiM team has applied a precision tribal home visiting approach to enhance methods of early intervention for children with DD. Our enhancement process was grounded in Indigenous community-based participatory research that centered culture and language.

Extrauterine growth restriction in very-low-birthweight infants: prevalence and concordance according to Fenton, Olsen, and INTERGROWTH-21st growth charts in a multicenter Spanish cohort.

Multiple criteria and growth references have been proposed for extrauterine growth restriction (EUGR). We hypothesized that these may impact the diagnosis of EUGR. The objective was to evaluate the prevalence of EUGR with its different definitions and the concordance according to Fenton, Olsen, and INTERGROWTH-21st in very-low-birthweight (VLBW) infants. This is an observational, retrospective, and multicenter study including VLBW infants from the Spanish SEN1500 Network from 2011 to 2020. Patients with major congenital anomalies, embryopathies, and gestational age less than 24 weeks were excluded. EUGR prevalence was calculated at discharge with cross-sectional, longitudinal, "true" cross-sectional, and "true" longitudinal definitions. Concordance was assessed with Fleiss' kappa coefficient. 23582 VLBW infants from 77 NICUs were included. In total, 50.4% were men with a median of gestational age of 29 (4) weeks. The prevalence of EUGR (cross-sectional, longitudinal, and "true") was variable for weight, length, and head circumference. Overall, the prevalence was higher with Fenton and lower with Olsen (cross-sectional and "true" cross-sectional) and INTERGROWTH-21st (longitudinal and "true" longitudinal). Agreement among the charts by weight was good only for cross-sectional EUGR and moderate for longitudinal, "true" cross-sectional, and "true" longitudinal. Concordance was good or very good for EUGR by length and head circumference.Conclusions: The prevalence of EUGR with the most commonly used definitions was variable in the cohort. Agreement among growth charts was moderate for all the definitions of EUGR by weight except cross-sectional and good or very good for length and head circumference. The choice of reference chart can impact the establishment of the diagnosis of EUGR. What is known: • EUGR has been defined in the literature and daily practice considering weight, length and head circumference with multiple criteria (cross-sectional, longitudinal, and "true" definition) • Different growth charts have been used for EUGR diagnosis What is new: • Prevalence of EUGR is variable depending on the definition and growth chart used in our cohort of VLBW infants • For the most frequently EUGR criteria used, traditionally considering weight, concordance among Fenton, Olsen and INTERGROWTH-21st growth charts is only moderate for all the definitions of EUGR by weight except cross-sectional definition. Concordance among the charts is good or very good for the different criteria of EUGR by head circumference and length.

Using a longitudinal qualitative approach to understand the lived experiences of caregivers of infants with obstructive sleep apnea who require chronic noninvasive respiratory support.

OBJECTIVE: Although positive airway pressure (PAP) is effective for treating obstructive sleep apnea (OSA) in infants, there is a lack of data on caregivers' experiences administering PAP at home. Understanding caregivers' perspectives may change health care professionals approach to PAP initiation. Our study aimed to gain comprehensive insight into caregivers' beliefs, perceptions, and challenges associated with implementing PAP for infants with OSA, considering the transition from inpatient hospitalization to home. METHODS: In this single-center prospective longitudinal study, caregivers of infants with OSA less than 12 months old who were initiated PAP during inpatient hospitalization underwent two semi-structured interviews over 3 months. The interview data were analyzed using directed content analysis, utilizing the health belief and socioecological models as theoretical frameworks. Data were coded and clustered into themes that reflected the evolving perspectives and experiences of caregivers. RESULTS: Eight caregivers completed semi-structured interviews, revealing three key themes. First, despite initial negative attitudes towards the equipment, caregivers recognized PAP benefits and through self-efficacy and cues to action, were motivated to use PAP at home. Second, caregivers encountered various barriers to adherence; however, caregivers' self-efficacy improved with time and practice. Lastly, interpersonal, organizational, and community support enhanced adherence while lack thereof hindered implementation. CONCLUSION: Caregivers of infants with OSA understand the importance of PAP therapy. Providing family-centered care and targeted interventions helps caregivers maintain adherence to PAP for infants. By understanding the lived experiences of caregivers, health care professionals can better meet the needs of families and optimize the effectiveness of PAP.

Nonsurgical improvement of severe upper airway obstruction in infants with Robin sequence and cleft palate using Stanford Orthodontic Airway Plate treatment.

STUDY OBJECTIVES: Severe respiratory distress of neonates with Robin sequence (RS) is traditionally managed by surgery. Stanford Orthodontic Airway Plate treatment (SOAP) is a nonsurgical option. The study aimed to determine if SOAP can improve polysomnography (PSG) parameters of neonates with RS. METHODS: PSG of neonates with RS treated with SOAP at a single hospital were retrospectively analyzed. Patients without PSG at all 4 time points (pre-, start of-, mid-, and post-treatment) were excluded. Data were analyzed using a linear mixed effects model. RESULTS: Sixteen patients were included. All patients had cleft palate (CP). The median age (min, max) at the start of treatment was 1.1 months (0.5, 2.3) with the treatment duration of 4.5 months (3.5, 6.0). The mean obstructive apnea-hypopnea index (95% confidence interval) decreased from 39.3 events/hour (32.9, 45.7) to 12.2 events/hour (6.7, 17.7) (P < 0.001), obstructive apnea index decreased from 14.1 (11.2, 17.0) events/hour to 1.0 (-1.5, 3.5) events/hour (P < 0.001), and oxygen nadir increased from 79.9% (77.4, 82.5) to 88.2% (85.5, 90.8) (P < 0.001) between pre- and start of treatment. Respiratory improvements were sustained during and after the treatment. All patients avoided mandibular distraction osteogenesis or tracheostomy following SOAP. CONCLUSIONS: As being a rare diagnosis, the number of participants was, as expected, low. However, the current study demonstrates that SOAP can improve PSG parameters, demonstrating its potential utility before surgical interventions for neonates with RS and CP experiencing severe respiratory distress.

Systemic hemodynamics and pediatric lung disease: Mechanistic links and therapeutic relevance.

Chronic lung disease, also known as bronchopulmonary dysplasia affects thousands of infants worldwide each year. The impact on resources is second only to bronchial asthma, with lung function affected well into adolescence. Diagnostic and therapeutic constructs have almost exclusively focussed on pulmonary architecture (alveoli/airways) and pulmonary hypertension. Information on systemic hemodynamics indicates major artery thickness/stiffness, elevated systemic afterload and/or primary left ventricular dysfunction may play a part in a subset of infants with severe neonatal-pediatric lung disease. Understanding the underlying principles with attendant effectors would aid in identifying the pathophysiological course where systemic afterload reduction with angiotensin converting enzyme inhibitors could become the preferred treatment strategy over conventional pulmonary artery vasodilatation.
