ABSTRACT
PURPOSE: Improving the deep lung delivery of aerosol surfactant therapy (AST) with a dry powder formulation may enable significant reductions in dose while providing improved efficacy. The objective of Part I of this two-part study was to present the development of a new dry powder aerosol synthetic lung surfactant (SLS) product and to characterize performance based on aerosol formation and realistic in vitro airway testing leading to aerosol delivery recommendations for subsequent in vivo animal model experiments. METHODS: A new micrometer-sized SLS excipient enhanced growth (EEG) dry powder formulation was produced via spray drying and aerosolized using a positive-pressure air-jet dry powder inhaler (DPI) intended for aerosol delivery directly to intubated infants with respiratory distress syndrome (RDS) or infant-size test animals. RESULTS: The best-case design (D2) of the air-jet DPI was capable of high emitted dose (> 80% of loaded) and formed a < 2 µm mass median aerodynamic diameter (MMAD) aerosol, but was limited to ≤ 20 mg mass loadings. Testing with a realistic in vitro rabbit model indicated that over half of the loaded dose could penetrate into the lower lung regions. Using the characterization data, a dose delivery protocol was designed in which a 60 mg total loaded dose would be administered and deliver an approximate lung dose of 14.7-17.7 mg phospholipids/kg with a total aerosol delivery period < 5 min. CONCLUSIONS: A high-efficiency aerosol SLS product was designed and tested that may enable an order of magnitude reduction in administered phospholipid dose, and provide rapid aerosol administration to infants with RDS.
ABSTRACT
AIMS: Gastro-oesophageal reflux is common in newborns, especially in premature infants. Treatment by medication is controversial as the drugs prescribed have not been consistently proven to be effective and are known to have adverse effects. This study sought to identify trends in the prescription of anti-reflux medication in a large group of French neonatal units. METHODS: Data on prescriptions of anti-reflux treatments-proton pump inhibitors (PPIs), antacids, histamine-2 receptor antagonists (H2RAs), and prokinetics-from 2014 to 2022 for infants with a corrected gestational age <45 weeks, were extracted from a prescription database (Logipren®) used by 63 French neonatal units, and then analysed. RESULTS: Of all infants recorded in the database during the study period (n = 152 743), 10.2% (n = 15 650) were prescribed anti-reflux medication (95% confidence interval [CI] 10.0-10.4%), mainly as monotherapy (77.5%). The rate was higher in the subgroup of preterm infants born before 28 weeks of gestation (n = 9493) (20.6%, 95% CI 19.8-21.4%; n = 1956). PPIs were the most commonly prescribed anti-reflux medications (6.9% of infants, 95% CI 6.8-7.0), followed by antacids (5.2%, 95% CI 5.1-5.3%), while H2RAs and prokinetics were rarely prescribed. Over the period, the prescription rate remained stable for PPIs, decreased for H2RAs (τ = -0.86, P = .02), and, among preterm infants born at gestational ages of 28-31 or 32-36 weeks, increased for antacids. CONCLUSIONS: Anti-reflux medications were frequently prescribed by neonatal units, especially for extremely premature infants. Most of these prescriptions were for PPIs and antacids.
ABSTRACT
PURPOSE: Human breastmilk is the optimal nutrition for infants; however, preliminary research suggests that women who experience intimate partner violence (IPV) are less likely to initiate and continue breastfeeding. Self-efficacy is a known facilitator to achieve positive breastfeeding outcomes. This study aimed to explore the relationship between experiencing IPV and breastfeeding duration, exclusivity, and self-efficacy for Canadian mothers, and to identify potential variables that influence breastfeeding decision-making among women with experiences of IPV. METHOD: This was a cross-sectional secondary analysis of surveys completed by 129 mothers with children under the age of 2 years from Ontario, Canada. Data were stratified according to those who had experienced IPV and those who had not. Breastfeeding outcomes assessed included breastfeeding self-efficacy and breastfeeding duration and exclusivity. Non-parametric tests and correlations were used to determine if relationships existed between IPV and breastfeeding outcomes. RESULTS: 72.3% (n = 94) of women in this sample breastfed their child(ren). Experiencing IPV was associated with lower breastfeeding self-efficacy scores (W = 768, p = 0.055) with a moderate effect size (r = 0.32 [95% 0.06,0.55]). This relationship was significant in the context of psychological abuse (W = 816.5, p = 0.015) with a small effect size (r = 0.22 [95% 0.03,0.41]). CONCLUSIONS: This study provides novel preliminary evidence suggesting that experiencing IPV of any type can negatively impact breastfeeding self-efficacy, with psychological abuse potentially being the most detrimental. Future research is required to build upon these findings.
ABSTRACT
This case report describes the case of a female infant hospitalized for severe pneumonia. During the treatment process, various antibiotics are used to treat and prevent further infection. The child had a weak physical condition, combined with neuroblastoma, paraneoplastic syndrome, and low immune function, leading to Tsukamurella tyrosinosolvens infection. The treatment was eventually abandoned owing to poor prognosis. This study aims to through the medium, dyeing, electron microscope observation, 16s rRNA and high-throughput sequencing investigated the morphological characteristics, staining properties, electron microscope morphology, antibiotic resistance, and genomic characteristics of Tsukamurella tyrosinosolvens. The aim of the study is to provide data reference for clinical laboratory staff in bacteria identification research, and to provide relevant help for clinicians in diagnosis and treatment.
ABSTRACT
OBJECTIVE: Therapeutic alliance has been little investigated in infant and toddler therapy, with no tools specifically adapted to this population. However, we have developed the Infant-Toddler Working Alliance Inventory-Short form (IT-WAI-S) which is based on the Working Alliance Inventory. The aim of this study was to assess the psychometric properties of this original French tool, in its two versions: for parent (IT-WAI-SP) and for therapist (IT-WAI-STh). METHOD: This study included 227 families consulting with their 18-48-month-old child for emotional or behavioral disorders. The scales were filled in at the first three therapy sessions. The IT-WAI-S acceptability, internal validity, reliability and predictive validity (association with child and mother's outcomes) were evaluated. RESULTS: Confirmatory then exploratory factor analyses revealed a three-factor structure for the both scales: Negative Experience of Care Relationship, Positive Alliance and Alliance with the Child. Acceptability, reproducibility and construct validity were satisfactory for both versions. The two versions predicted the child's outcome. The IT-WAI-SP predicted also the mother's outcome. The IT-WAI-STh gave more reproducible results, whereas the IT-WAI-SP was a better predictor of the child's progress. CONCLUSION: The two IT-WAI-S versions showed good psychometric properties and could be used to study the therapeutic alliance in young children.
ABSTRACT
Waleszczynski critiques my argument for why the relationship between a pregnant person and any fetus they carry is not a relationship between a parent and a child. I argue Waleszczynski does not show that my 'argument from potentiality' is inadequate, and I provide further justification for why birth marks a transformative shift into a moral relationship.
ABSTRACT
INTRODUCTION: The prevalence of Down syndrome (DS) is approximately 1 per 1000 births and is influenced by increasing maternal age over the last few decades. DS is strongly associated with congenital heart defects (CHDs), especially atrioventricular septal defect (AVSD). Our objectives were to investigate the prevalence of live-born infants with DS having a severe CHD in the Norwegian population over the last 20 years and compare outcomes in infants with AVSD with and without DS. MATERIAL AND METHODS: Information on all births from January 1, 2000 to December 31, 2019 was obtained from the Medical Birth Registry of Norway. We also obtained data on all infants with severe CHDs in Norway registered in Oslo University Hospital's Clinical Registry for Congenital Heart Defects during 2000-2019 and accessed individual-level patient data from the electronic hospital records of selected cases. Infants with AVSD and DS were compared to infants with AVSD without chromosomal defects. Crude and adjusted odds ratios (ORs) of infant mortality and need for surgery during the first year of life, with associated 95% confidence intervals (CIs), were estimated by logistic regression. RESULTS: A total of 1 177 926 infants were live-born in Norway during the study period. Among these, 1456 (0.1%) had DS. The prevalence of infants with DS having a severe CHDs was relatively stable, with a mean of 17 cases per year. The most common CHD associated with DS was AVSD (44.4%). Infants with AVSD and DS were more likely to have cardiac intervention during their first year of life compared to infants with AVSD without chromosomal defects (adjusted OR [aOR]: 2.52; 95% CI 1.27, 4.98). However, we observed no difference in infant mortality during first year of life between the two groups (aOR: 1.08; 95% CI 0.43, 2.70). CONCLUSIONS: The prevalence of live-born infants with severe CHDs and DS has been stable in Norway across 20 years. Infants with AVSD and DS did not have higher risk of mortality during their first year of life compared to infants with AVSD without chromosomal defects, despite a higher risk of operative intervention.
ABSTRACT
Cystic fibrosis (CF) results in chronic pulmonary infections, inflammation, pancreatic insufficiency, and multiple gastrointestinal manifestations. Malnutrition and poor growth are hallmarks of CF, and strongly associated with poor outcomes. Through newborn screening, many infants can be diagnosed within a few days of life, which allows for early initiation of nutritional counseling and close clinical follow-up. Obstacles to growth for infants with CF start in utero, as newborns with CF can have a lower birth weight than the general population. Improving infant growth has been linked to improved clinical outcomes and survival. It remains a top priority and challenge for caregivers and healthcare teams. An interdisciplinary approach, including registered dietitian and social work support, is essential to optimize health for infants with CF. Remaining barriers to normalcy include deficits in linear growth, lack of accurate nutrition biomarkers, persistence of inequities related to social determinant of health, particularly in the global CF community.

BACKGROUND: The common cause of sodium nitrite poisoning has shifted from previous accidental intoxication by exposure or ingestion of contaminated water and food to recent alarming intentional intoxication as an employed method of suicide/exit. The subsequent formation of methemoglobin (MetHb) restricts oxygen transport and utilization in the body, resulting in functional hypoxia at the tissue level. In clinical practice, a mismatch of cyanotic appearance and oxygen partial pressure usually contributes to the identification of methemoglobinemia. Prompt recognition of characteristic mismatch and accurate diagnosis of sodium nitrite poisoning are prerequisites for the implementation of standardized systemic interventions. CASE SUMMARY: A pregnant woman was admitted to the Department of Critical Care Medicine at the First Affiliated Hospital of Harbin Medical University due to consciousness disorders and drowsiness 2 h before admission. Subsequently, she developed vomiting and cyanotic skin. The woman underwent orotracheal intubation, invasive mechanical ventilation (IMV), and correction of internal environment disturbance in the ICU. Her premature infant was born with a higher-than-normal MetHb level of 3.3%, and received detoxification with methylene blue and vitamin C, supplemental vitamin K1, an infusion of fresh frozen plasma, as well as respiratory support via orotracheal intubation and IMV. On day 3 after admission, the puerpera regained consciousness, evacuated the IMV, and resumed enteral nutrition. She was then transferred to the maternity ward 24 h later. On day 7 after admission, the woman recovered and was discharged without any sequelae. CONCLUSION: MetHb can cross through the placental barrier. Level of MetHb both reflects severity of the sodium nitrite poisoning and serves as feedback on therapeutic effectiveness.
ABSTRACT
Vitamin B12 deficiency is a rare entity in the pediatric population. It is often of maternal origin in exclusively breast-fed infants. Its clinical manifestations are multiple and unspecific, encompassing hematological problems and neurodevelopmental consequences. Positive diagnosis and early treatment with vitamin B12 supplementation have a rapidly reversible effect on symptoms. Delayed diagnosis, however, may result in irreversible neurological sequelae. We report the case of a six-month-old infant, admitted with hypotonia and psychomotor regression since the age of four months. The laboratory work-up revealed macrocytic anemia with the presence of megakaryocytes and megaloblasts on the myelogram. Vitamin B12 levels were low, and homocysteine levels were high. A maternal workup showed vitamin B12 deficiency in the mother. A brain MRI showed bilateral frontoparietal cortical atrophy. The patient was put on vitamin B12 supplementation with good evolution. The aim of our work is to shed light on the misleading and varied clinical profile of vitamin B12 deficiency in an exclusively breastfed infant, the serious consequences of maternal vitamin B12 deficiency, and the importance of early diagnosis of this condition.
ABSTRACT
Asthma, a chronic inflammatory disorder of the airways, is a prevalent childhood chronic disease with a substantial global health burden. The complex etiology and pathogenesis of asthma involve genetic and environmental factors, posing challenges in diagnosis, severity prediction, and therapeutic strategies. Recent studies have highlighted the significant role of the gut microbiota and its interaction with the immune system in the development of asthma. Dysbiosis, an imbalance in microbial composition, has been associated with respiratory diseases through the gut-lung axis. This axis is an interaction between the gut and lungs, allowing microbial metabolites to influence the host immune system. This systematic review examines the association between gut microbiota composition, measured using 16S rRNA sequencing, during infancy and childhood, and the subsequent development of atopic wheeze and asthma. The results suggest that higher alpha diversity of bacteria such as Bifidobacterium, Faecalibacterium, and Roseburia may have protective effects against asthmatic outcomes. Conversely, lower relative abundances of bacteria like Bacteroides and certain fungi, including Malassezia, were associated with asthma. These findings highlight the potential of early screening and risk assessment of gut microbiota to identify individuals at risk of asthma. Furthermore, investigations targeting gut microbiota, such as dietary modifications and probiotic supplementation, may hold promise for asthma prevention and management. Future research should focus on identifying specific microbial signatures associated with asthma susceptibility and further investigate approaches like fecal microbiota transplantation. Understanding the role of gut microbiota in asthma pathogenesis can contribute to early detection and development of interventions to mitigate the risk of asthmatic pathogenesis in childhood.
ABSTRACT
BACKGROUND: Benefits of different types of family-centred care (FCC) interventions in neonatal intensive care units (NICUs) have been reported. However, a comprehensive review of existing FCC intervention studies was lacking. OBJECTIVE: This review aimed at synthesising the characteristics of FCC interventions, related outcomes and measurement methods in randomised controlled trials (RCTs) in NICU, and providing menus of options to favour implementation and further research. METHODS: We searched PubMed, EMBASE, Web of Science and the Cochrane Library up to 31 January 2022. Interventions were mapped according to five categories as defined by a previous Cochrane review. We described outcome types, measurement populations, measurement methods and timelines. Subgroup analyses were also performed. RESULTS: Out of 6583 studies identified, 146 met eligibility criteria. Overall, 52 (35.6%) RCTs tested more than one category of intervention, with a large variety of combinations, with the most frequent category of intervention being the educational (138 RCTs, 94.5%). We identified a total of 77 different intervention packages, and RCTs comparing the same interventions were lacking. The 146 RCTs reported on 425 different outcomes, classified in 13 major categories with parental mental health (61 RCTs, 41.8% of total RCTs) being the most frequent category in parents, and neurobehavioural/developmental outcomes being the most frequent category in newborns (62 RCTs, 42.5%). For several categories of outcomes almost every RCT used a different measurement method. Educational interventions targeting specifically staff, fathers, siblings and other family members were lacking or poorly described. Only one RCT measured outcomes in health workers, two in siblings and none considered other family members. CONCLUSIONS: A large variety of interventions, outcomes and measurement methods were used in FCC studies in NICU. The derived menus of options should be helpful for researchers and policy makers to identify interventions most suitable in each setting and to further standardise research methods.

BACKGROUND: The World Health Organization (WHO) recommends that women with HIV breastfeed for a minimum of one year. In contrast, across high-income countries, HIV and infant-feeding guidelines recommend exclusive formula feeding if parents want to avoid all risk of postpartum transmission. However, recently these guidelines (including in the United Kingdom (UK)) increasingly state that individuals with HIV should be supported to breast/chest feed if they meet certain criteria; such as an undetectable maternal HIV viral load and consent to additional clinical monitoring. Between 600 and 800 pregnancies are reported annually in women with HIV in the UK, with low rates of vertical transmission (0.22%). Informed infant-feeding decision-making requires clinical support. Currently, little research addresses how individuals with HIV in high-income countries navigate infant-feeding decisions with their clinical teams and familial and social networks, and the resources needed to reach an informed decision. METHODS: Semi-structured remote interviews were conducted between April 2021 - January 2022 with UK-based individuals with a confirmed HIV diagnosis who were pregnant or one-year postpartum. Using purposive sampling, pregnant and postpartum participants were recruited through NHS HIV clinics, community-based organisations and snowballing. Data were analysed thematically and organised using NVivo 12. RESULTS: Of the 36 cisgender women interviewed, 28 were postpartum. The majority were of Black African descent (n = 22) and born outside the UK. The majority of postpartum women had chosen to formula feed. Women's decision-making regarding infant-feeding was determined by (1) information and support; (2) practicalities of implementing medical guidance; (3) social implications of infant-feeding decisions. CONCLUSION: The evolution of UK HIV and infant-feeding guidelines are not reflected in the experiences of women living with HIV. Clinicians' emphasis on reducing the risk of vertical transmission, without adequately considering personal, social and financial concerns, prevents women from making fully informed infant-feeding decisions. For some, seeking advice beyond their immediate clinical team was key to feeling empowered in their decision. The significant informational and support need among women with HIV around their infant-feeding options must be addressed. Furthermore, training for and communication by healthcare professionals supporting women with HIV is essential if women are to make fully informed decisions.

Introduction: In recent years, Poland has faced two major emergencies: the COVID-19 pandemic, a global-scale public health emergency in 2020, and the outbreak of a full-scale war in Ukraine, which forced over 9 million Ukrainians-mostly women and children-to flee from their country through the Polish-Ukrainian border in 2022. Methods: In 2020 and 2022, we conducted two online questionnaires with human milk bank personnel to assess the impact of these emergencies on the human milk banking sector and its preparedness to face them. All 16 human milk bank entities operating in Poland were contacted and invited to participate in the study. For the first questionnaire, which was distributed in 2020, we obtained a 100% response rate. For the second questionnaire, the response rate was 88%, i.e., 14 out of 16 human milk banks completed the questionnaire. We compared these two emergencies in terms of the extent to which the potential of the Polish human milk bank network was exploited to support vulnerable infants who were not breastfed. Results and discussion: Our findings indicate that recommendations to provide donor human milk to infants separated from their mothers during the COVID-19 pandemic were never fully implemented. Meanwhile, during the refugee crisis, national legislation allowing equal access to public healthcare for Ukrainian citizens were rapidly implemented, enabling a more effective response by human milk banks to support vulnerable infants. However, no specific measures were introduced to support refugees outside the standard criteria for donor human milk provision. Our results highlight the limited response from the sector during emergencies and the underutilization of the potential of a nationwide network of professional human milk banks. Drawing on Polish experiences, we emphasize the importance of having procedures and legal regulations regarding human milk banking in place even in non-crisis settings, which would facilitate a rapid emergency response. We also emphasize the need to include the implementation of emergency procedures in building a strong and resilient human milk banking system.
ABSTRACT
Limited data exist on South African children hospitalised with COVID-19 in district hospitals. We describe the presentation and outcomes of children admitted to a level 1 and 2 hospital and compare this with children admitted to a level 2 and 3 hospital. Contribution: This study highlights that young age is an important risk factor for hospitalisation with severe COVID-19. Infants with HIV exposure and prematurity are disproportionately represented among admissions. Furthermore, we notice a high number of children with current or new tuberculosis confirming the interplay between viral infections and childhood tuberculosis.
ABSTRACT
Background: Assessment of infant feeding knowledge, attitudes and practices of human immunodeficiency virus (HIV)-positive breastfeeding mothers may determine compliance with the chosen feeding method. Aim: The study assessed knowledge, attitudes and practices on infant feeding among HIV-positive breastfeeding mothers. Setting: The study was conducted at five clinics in the Chief Albert Luthuli sub-district of Mpumalanga, South Africa. Methods: A descriptive cross-sectional study with a convenient sample of 155 HIV-positive breastfeeding mothers. Results: More than half of the participants (54.8%) were knowledgeable of exclusive breastfeeding in general. However, less than half were knowledgeable of exclusive breastfeeding in the context of HIV (46.5%), mixed feeding (28.4%) and replacement feeding (49.0%). Most participants (85.8%) reported that they were advised to exclusively breastfeed for 6 months, 61.3% intended to exclusively breastfeed for 6 months, and 29% intended to stop breastfeeding at 6 months. Most participants (64.5%) intended to introduce solids at 6 months, and for participants who intended to introduce solids before 6 months, 37.7% did not believe that exclusive breastfeeding was sufficient for the baby. Conclusion: Although most participants were knowledgeable about exclusive breastfeeding, there were misconceptions that required attention such as the lack of knowledge on exclusive breastfeeding in the context of HIV, mixed feeding and replacement feeding. Exclusive breastfeeding for 6 months was the most emphasised infant feeding practice. Contribution: This study builds on existing literature on infant feeding knowledge, attitudes and practices and provides a basis for interventions for improved exclusive breastfeeding rates.
ABSTRACT
Background: Disturbed sleep during infancy and early childhood can have a detrimental effect on parental sleep and consequently parental well-being. However, there is a paucity of research on how perceived child sleep problems and behavioural sleep interventions as treatment influence maternal subjective well-being. Aim: This study aimed to explore the incidence of subjective well-being in mothers of children with sleep problems and whether implementing two behavioural sleep interventions changed their well-being. Setting: The research was conducted in a community setting, with parents voluntarily approaching a sleep consultancy based in South Africa. Method: Using data from 119 mothers voluntarily approaching a sleep consultancy in South Africa, a pre-test-post-test design was employed to investigate changes in life satisfaction, affect, couple satisfaction, perceived stress and depression approximately 3 weeks after implementation of a sleep intervention. Results: Results indicate that mothers of children with sleep problems experienced moderate to high life satisfaction and positive affect although the presence of moderate negative affect, couple satisfaction and stress and mild depression suggest possible decreased subjective well-being. Conclusion: Findings suggest implementation of graduated extinction and extinction with parental presence sleep interventions may improve life satisfaction, affect, stress and depression but not couple satisfaction in the short-term. Contribution: This study contributes towards understanding the effect of sleep loss on the subjective well-being of mothers and provides preliminary evidence regarding the benefits of two sleep interventions for improving maternal subjective well-being.
ABSTRACT
Unsettled infant behaviours are highly prevalent in the postnatal period and constitute a significant proportion of visits to healthcare services. Unsettled infant behaviours can be highly distressing for parents and are identified as a significant risk factor for postnatal depression. Understanding parents' experiences is paramount to reducing the gap between consumer expectations and service delivery. This study employed a qualitative descriptive approach to explore parents' experiences seeking healthcare advice for their infant with unsettled behaviours. Semi-structured interviews were conducted with 20 mothers. Inductive thematic analysis yielded two overarching themes: (1) 'the journey for answers', consisting of five sub-themes, and (2) 'parents' knowledge and behaviours', consisting of six sub-themes. Despite some positive interactions with healthcare services, mothers generally spoke negatively of their overall experience seeking answers and receiving care for their infant, and they felt the healthcare services they attended were not equipped to meet their needs. To address the gap between service delivery and consumer expectations, mothers relied on online communities for advice and emotional support. The findings of this study highlight several discrepancies between mothers' expectations and service delivery in the context of unsettled infant behaviours, and this paper makes recommendations to address identified shortcomings in approaches to care.
ABSTRACT
Approximately 15 million babies are born preterm (<37 weeks of completed gestation) worldwide annually. Although neonatal and perinatal medicine have contributed to the increased survival rate of preterm newborn infants, premature infants are at increased risk of mortality in the first years of life. Infants born preterm are at four times the risk of Sudden Infant Death Syndrome (SIDS) compared to infants born at term. SIDS is believed to be multifactorial in origin. The Triple Risk hypothesis has been proposed to explain this. The model suggests that when a vulnerable infant, such as one born preterm, is at a critical but unstable developmental period in homeostatic control, death may occur if exposed to an exogenous stressor, such as being placed prone for sleep. The highest risk period is at ages 2-4 months, with 90 % of deaths occurring before 6 months. The final pathway to SIDS is widely believed to involve some combination of immature cardiorespiratory control and a failure of arousal from sleep. This review will focus on the physiological factors which increase the risk for SIDS in preterm infants and how these factors may be identified and potentially lead to effective preventative strategies.
