Early Human Development

BACKGROUND: Preterm infants are at risk of developing both intraventricular hemorrhage (IVH) and anemia of prematurity. Several studies reported an association between early postnatal red blood cell (RBC) transfusion and IVH, however the timing and causality between these two remains unclear. AIMS: To describe the temporal sequence between administration of early RBC transfusion (within the first week of life) and diagnosis of IVH in very preterm infants. STUDY DESIGN: Retrospective single center case-series...

OBJECTIVE: to verify the relationship between the level of trunk control and the acquisition of gross motor skills in the first year of life. METHODS: a searching strategy was developed using the PICO tool and performed in the databases PubMed, Cochrane Library, Virtual Library in Health, Embase, and Scopus, from September 2020 to July 2022. The methodological quality of the articles was evaluated by the Ottawa Quality Assessment Scale Cohort Studies (NOS). RESULTS: six studies that evaluated the level of trunk control and gross motor development in infants aged 4 to 12 months were found...

OBJECTIVES: Neonatal trials have traditionally used binary composite short-term (such as death or bronchopulmonary dysplasia) or longer-term (such as death or severe neurodevelopmental impairment) outcomes. We applied the Desirability Of Outcome Ranking (DOOR) method to rank the overall patient outcome by best (no morbidities) to worst (death). STUDY DESIGN: Using a completed large multicenter trial (Milking In Non-Vigorous Infants [MINVI]) of umbilical cord milking (UCM) vs...

BACKGROUND: Tissue hypoxia remains a leading cause of morbidity and mortality in preterm infants. Current biomarkers often detect irreversible hypoxic cellular injury (i.e. lactate) and are non-specific. A new biomarker is needed which detects tissue hypoxia before irreversible damage occurs. AIMS: To investigate the relation between serum ischemia modified albumin (IMA), a marker of hypoxia; and analytic variables, patient related variables and conditions associated with hypoxia, in preterm infants...

Breastfeeding is recognized worldwide as the best option for infant feeding. Expressing breast milk is an alternative for mothers to provide their infants all the benefits of maternal milk. During breast milk expression, mothers receive a distinct kind of sensory stimulation, because there is no direct bodily or affective interaction with their infants, many women report feeling isolated, generating a love-hate relation with pumping, and even low levels of satisfaction while expressing breast milk. While it is well known that the prefrontal, parietal, and temporal cortices play important roles in the emotional and cognitive processing of maternal stimuli, knowledge about how these cortical areas function during breastfeeding is lacking...

BACKGROUND: The impact of prematurity status on attachment quality remains indeterminate. Some studies found no differences between infants born preterm (PT) and infants born full-term (FT), while other investigations present opposite results. AIMS: We aim to contribute to this body of research by studying mother-infant interactive behaviors and quality of attachment in 3 independent samples: Full-Term (FT), Moderate-to-Late Preterm (MLPT) and Very-to-Extreme Preterm (VEPT)...

BACKGROUND: Telehealth can be a viable option for improving equitable access to early motor assessment for financially vulnerable individuals. AIM: This review aimed to identify the psychometric properties of the Alberta Infant Motor Scale (AIMS) when applied via telehealth and assess its feasibility. METHODS: Papers were systematically retrieved from electronic databases until October 4, 2023. We included studies that assessed the motor development of infants using the AIMS through telehealth...

BACKGROUND: The spread of the COVID-19 virus was declared a pandemic in March 2020. New restrictions such as 'lockdowns' and 'social distancing' created challenges for individuals' work-life balance, financial situation, family life, and physical and mental health. The global population's stress levels rose in response to these changes, leading to a widespread deterioration of mental health. One group particularly affected was parents of infants and very young children. Poor parental mental health may disrupt parent-infant bonding, with negative consequences for infant well-being and development...

BACKGROUND: Covid-19 severity shows a sex difference (males>females) and progressive hypoxia among the most seriously affected. Digit ratios are sexually dimorphic and may be negatively-related to prenatal (2nd-to-4th digits' ratio; 2D:4D) and pubertal (3rd-to-5th digits' ratio; 3D:5D) testosterone. Oxygen therapy is important in Covid-19 treatment and low 2D:4D is linked to efficient oxygen metabolism. We consider relationships between digit ratios and duration of oxygen treatment in hospitalized Covid-19 patients...

BACKGROUND: Surfactant protein C (SP-C) disorder is a major component of hereditary interstitial lung disease (HILD) among Japanese. The correlation between clinical outcomes and the phenotype/genotype of SP-C disorder has not been evaluated comprehensively. The current study aimed to evaluate the phenotype/genotype correlated with poor outcomes in patients with SP-C disorder. METHODS: Sequencing analysis of SFTPC in 291 candidates with HILD was performed. The phenotype and genotype correlated with poor outcomes were examined...

The study employs a longitudinal approach, meticulously tracking trends in scholarly output, international collaborations, and authorship patterns. Notably, our findings reveal a significant increase in GMA-related publications, highlighting the growing prominence of this field...

INTRODUCTION: Necrotizing enterocolitis (NEC) is one of the most common gastrointestinal emergencies affecting very low birth weight (VLBW) infants with an incidence of 6-15 %. Early recognition is crucial. Mortality is high and variable (30-50 %). Those requiring surgical intervention have a higher mortality rate than those who receive medical treatment. OBJECTIVES: 1) To assess the prevalence of surgical NEC and associated risk factors 2) To compare outcomes based on the type of treatment required 3) To estimate the mortality associated with NEC and surgical NEC...

BACKGROUND: Infants with complex congenital heart disease are at increased risk of impaired fetal brain growth, brain injury, and developmental impairments. The General Movement Assessment (GMA) is a valid and reliable tool to predict cerebral palsy (CP), especially in preterm infants. Predictive properties of the GMA in infants with complex congenital heart disease (CCHD) are unknown. AIM: To evaluate predictive properties of the GMA to predict developmental outcomes, including cerebral palsy (CP), at 18-months corrected age (CA) in children with CCHD undergoing heart surgery in the first month of life...

BACKGROUND: Low birth weight (LBW) is a significant global health concern with potential health risks and developmental implications for infants. Catch-up growth, an accelerated growth following an inhibition period, may partially compensate for growth deficits in LBW children. AIMS: This study investigated the prevalence of LBW and catch-up growth in height, weight, and body mass index (BMI) among LBW children in Japan, identified factors associated with LBW, and explored the potential for catch-up growth at different ages up to seven years...

BACKGROUND: Sleep consolidation into nighttime is considered the primary goal of sleep development in early infants. However, factors contributing to sleep consolidation into nighttime remain unclear. AIM: To clarify the influences of the light environment and nighttime co-sleeping on sleep consolidation into nighttime in early infants. STUDY DESIGN: Cross-sectional study. SUBJECTS AND METHODS: Sleep-wake time and light stimulation were measured in infants for 4 consecutive days using actigraphy...

BACKGROUND: Prematurity is associated with reduced cardiac autonomic function. This study aimed to investigate the heart rate variability (HRV) in school-age children born moderately to late preterm (MLPT). METHODS: This cross-sectional study investigated school-age children, aged 5 to 10 years, born moderate-to-late preterm. Electrocardiograms recordings were performed during fifteen-minutes. Time and frequency domain parameters were calculated, corrected for heart rate and compared between the groups...

BACKGROUND: Parents play a vital role in promoting infant motor development and physical activity; however, there is little information available to parents on how to support healthy movement. Therefore, the purpose of this study was to assess the feasibility of implementing video-based education to improve infant physical activity and motor development. METHODS: This multiple case study consisted of semi-structured interviews with mothers (n = 12) and early childhood experts (n = 5, e...

BACKGROUND: Childhood outcomes following preterm birth are widely published, however long-term adult outcomes are less well described. We aimed to determine the quality of life and burden of co-morbidities experienced by preterm-born young adults in Western Australia. METHODS: A retrospective observational study was conducted. Participants born at 23-33 weeks gestation cared for at King Edward Memorial Hospital during 1990 and 1991 were recruited from a historical birth cohort...

OBJECTIVE: To describe the association between intermittent hypoxemic events (IHEs) and severe neurodevelopmental impairment (SNDI) or death in extremely premature infants. STUDY DESIGN: Retrospective study of extremely premature infants 230/7 -276/7 weeks gestational age (GA) and birthweight (BW) ≤1250 grams (g) admitted to a level IV neonatal intensive care unit (NICU) from 2013 to 2017. IHEs, defined as events with SpO2  ≤ 80 % lasting 10 s to 5 min, were algorithmically identified using data extracted from bedside monitors at 2 s intervals (0...
