Exposure of preterm neonates to toxic metals during their stay in the Neonatal Intensive Care Unit and its impact on neurodevelopment at 2 months of age. J Trace Elem Med Biol 2023; 78:127173. [PMID: 37060676 DOI: 10.1016/j.jtemb.2023.127173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 10/27/2022] [Accepted: 04/04/2023] [Indexed: 04/17/2023]
Abstract
BACKGROUND Premature neonates might be exposed to toxic metals during their stay in the neonatal intensive care unit (NICU), which could adversely affect neurodevelopment; however, limited evidence is available. The present study was therefore designed to assess the exposure to mercury, lead, cadmium, arsenic, and manganese of preterm neonates who received total parenteral nutrition (TPN) and/or red blood cell (RBC) transfusions during their NICU stay and the risk of neurodevelopment delay at the age of 2 months. METHODS We recruited 33 preterm neonates who required TPN during their NICU admission. Blood samples were collected for metal analysis at two different time points (admission and before discharge). Metals in the daily TPN received by preterm neonates were analyzed. Neurodevelopment was assessed using the Ages and Stages Questionnaire Edition 3 (ASQ-3). RESULTS All samples of TPN had metal contamination: 96% exceeded the critical arsenic limit (0.3 μg/kg body weight/day); daily manganese intake from TPN for preterm neonates exceeded the recommended dose (1 µg/kg body weight) as it was added intentionally to TPN solutions, raising potential safety concerns. All samples of RBC transfusions exceeded the estimated intravenous reference dose for lead (0.19 µg/kg body weight). Levels of mercury, lead and manganese in preterm neonates at discharge decreased 0.867 µg/L (95% CI, 0.76, 0.988), 0.831 (95%CI, 0.779, 0.886) and 0.847 µg/L (95% CI, 0.775, 0.926), respectively. A decrease in ASQ-3-problem solving scores was associated with higher levels of blood lead in preterm neonates taken at admission (ß = -0.405, 95%CI = -0.655, -0.014), and with plasma manganese (ß = -0.562, 95%CI = -0.995, -0.172). We also observed an association between decreased personal social domain scores with higher blood lead levels of preterm neonates before discharge (ß = -0.537, 95%CI = -0.905, -0.045). CONCLUSION Our findings provide evidence to suggest negative impacts on the neurodevelopment at 2 months of preterm infants exposed to certain metals, possibly related to TPN intake and/or blood transfusions received during their NICU stay. Preterm neonates may be exposed to levels of metals in utero.

Sports participation and preterm birth: a nationwide birth cohort in Japan. Pediatr Res 2022; 92:572-579. [PMID: 34707251 DOI: 10.1038/s41390-021-01808-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 08/08/2021] [Accepted: 10/09/2021] [Indexed: 11/09/2022]
Abstract
BACKGROUND Children born preterm may be less physically active than children born term because of neurocognitive problems, reduced lung function, and poor physical fitness. We evaluated sports participation of children and adolescents who had been born preterm (<37 weeks) and early term (37-38 weeks) in 2001. METHODS Data from a nationwide longitudinal survey (n = 47,015, including 2375 children born preterm) were analyzed. As indicators of sports participation, we used responses to questions about participation in sports clubs at 7 and 10 years old and in extracurricular school sports at 15 years old. RESULTS Children born very preterm (25-31 weeks) and moderately to late preterm (32-36 weeks) were less likely to participate in sports clubs at 7, 10, and 15 years old than children born full term (39-41 weeks). Compared with children born full term, the adjusted risk ratios for participation in extracurricular school sports at 15 years old were 0.86 (95% confidence interval: 0.75-0.98) for children born very preterm, 0.92 (0.88-0.97) for children born moderately to late preterm, and 1.00 (0.98-1.02) for children born early term. CONCLUSIONS Our findings suggest that preterm birth is associated with less participation in organized sports during childhood and adolescence than full-term birth. IMPACT Research investigating associations between preterm birth and physical activity among children born in the 2000s is limited. This study shows that preterm birth was associated with less participation in organized sports during childhood and adolescence than full-term birth, especially in boys, and the participation in organized sports of children born preterm decreased as gestation shortened. During childhood, boys born early term were also less likely to participate in organized sports than boys born full term, suggesting a continuum with preterm births. These findings offer important additional insights into the limited evidence available for predicting future health outcomes for preterm infants.

Acta Obstet Gynecol Scand 2021; 101:153-162. [PMID: 34780056 DOI: 10.1111/aogs.14285] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 10/12/2021] [Accepted: 10/15/2021] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Although the perinatal mortality of monochorionic twins has been reported to be higher, the role of chorionicity is debated and data from Finland are still lacking. To examine the effect of chorionicity on the main outcome measures, perinatal and neonatal mortality and neonatal morbidity of Finnish twins, a comprehensive population-based historical cohort study was performed at Helsinki University Hospitals. MATERIAL AND METHODS All 1034 dichorionic and monochorionic-diamniotic twin pregnancies managed at Helsinki University Hospital area during 2006, 2010, 2014 and 2018 were collected from patient databases. Information on chorionicity was retrieved from ultrasound reports and all relevant clinical information from patient records. Differences in perinatal and neonatal mortality and neonatal morbidity were analyzed by performing group comparisons between the twins and chorionicity. The role of chorionicity was also assessed in logistic regression analyses. RESULTS There were 1034 dichorionic-diamniotic (DCDA, n = 789, 76.3%, 95% confidence interval [CI] 73.6-78.9) and monochorionic-diamniotic (MCDA, n = 245, 23.7%, 95% CI 21.4-26.0) twin pregnancies during the studied years. Most (n = 580, 56.1%, 95% CI 52.8-59.2) twins were born at term, but 151 (61.6%, 95% CI 55.8-67.3) of MCDA twins were preterm and had lower birthweight and Apgar scores and higher risk of death of one twin. Perinatal and neonatal mortality did not differ between twins A and B, but the immediate outcome of twin B was worse, with lower arterial pH and Apgar scores and increased need of neonatal intensive care unit treatment. CONCLUSIONS Chorionicity contributes to the perinatal and neonatal outcome in favor of dichorionic twins. This disadvantage of MCDA twinning is likely explained by earlier gestational age at birth and inequal placental sharing. Irrespective of chorionicity, twin B faces more complications.

Abstract
PURPOSE To study the association between television-watching in the earlier years of life and subsequent parents' concerns about decreased visual acuity in their elementary school-aged child. STUDY DESIGN Population-based longitudinal cohort. METHODS Television-watching and its daily duration, as the main exposure, and parents' concerns for their child's decreased visual acuity during the school years, as the main outcome, were picked up from yearly questionnaires performed for the Longitudinal Survey of Newborns in the Twenty-First Century involving all babies born in Japan during either of two periods: between January 10 and 17, 2001 or between July 10 and 17, 2001 (N = 47,015). RESULTS Television-/video-watching as the main form of play of children at the ages of 1.5 years and 2.5 years was significantly associated with parents' concerns for their child's decreased visual acuity raised once or more in six surveys conducted between the ages of 7 and 12 years (odds ratio, 1.1 and 1.09; 95% CI 1.05-1.15 and 1.04-1.14, respectively). The association remained significant after adjustment for confounding variables, including child's sex, preterm birth, multiple birth, mother's age at delivery, mother's and father's education, and residential area. Longer daily duration of television-watching at 2.5 years was significantly associated with concerns for the child's decreased visual acuity between the ages of 7 and 12 years, but not at the ages of 3.5, 4.5, and 5.5 years. The association remained significant in a sensitivity analysis of 28,820 children who participated in all six surveys. CONCLUSIONS Longer daily exposure to television in children in the earlier years of life was associated with parents' subsequent concerns about decreased visual acuity in their elementary school-aged child.

Abstract
OBJECTIVE To study the perinatal complications of late preterm twins (LPTs) versus early term twins (ETTs). METHODS A retrospective analysis was performed for the complications of 246 LPTs, 496 ETTs, and their mothers. The risk factors for late preterm birth were analyzed. According to gestational age, the twins were divided into five groups: 34-34+6 weeks (n=44), 35-35+6 weeks (n=70), 36-36+6 weeks (n=132), 37-37+6 weeks (n=390), and 38-38+6 weeks (n=106). The perinatal complications were compared between groups. RESULTS Maternal hypertension, maternal thrombocytopenia, placenta previa, and premature rupture of membranes were independent risk factors for late preterm birth in twins (P < 0.05). The LPT group had higher incidence rates of respiratory diseases, feeding intolerance, and hypoglycemia than the ETT group (P < 0.05). The 34-34+6 weeks group had a higher incidence rate of neonatal asphyxia than the 37-37+6 weeks and 38-38+6 weeks groups; and had a higher incidence rate of septicemia than 36-36+6 weeks group (P < 0.0045). The 34-34+6 weeks and 35-35+6 weeks groups had higher incidence rates of neonatal respiratory distress syndrome, neonatal apnea, and anemia than the other three groups; and had higher incidence rates of neonatal pneumonia, hypoglycemia and septicemia than the 37-37+6 weeks and 38-38+6 weeks groups (P < 0.0045). The 35-35+6 weeks group had a higher incidence rate of feeding intolerance than the 36-36+6 weeks, 37-37+6 weeks, and 38-38+6 weeks groups (P < 0.0045). The 36-36+6 weeks group had a lower incidence rate of hypoglycemia than the 34-34+6 weeks group and a higher incidence rate of hypoglycemia than the 37-37+6 weeks group (P < 0.0045). CONCLUSIONS Compared with ETTs, LPTs have an increased incidence of perinatal complications. The incidence of perinatal complications is associated with gestational ages in the LPTs and ETTs.

Abstract
OBJECTIVE To examine the association of specific Z-score categories of birth weight for gestational age with child health and neurodevelopment using a large nationwide survey in Japan, focusing on term infants. STUDY DESIGN We included 36 321 children born in 2010. Hospitalization up to 66 months of age was used as an indicator of health status, and responses to questions about age-appropriate behaviors at 30 and 66 months of age were used to indicate neurobehavioral development. We conducted binomial log-linear regression analyses, controlling for child and parental variables. A restricted cubic spline function was used to model the relationship. RESULTS Compared with children with birth weight appropriate for gestational age (-1.28 to 1.28 SDs of expected birthweight for gestational age), children who were small for gestational age (SGA) (<-1.28 SD) had higher risks of hospitalization and unfavorable neurobehavioral development, and the risks increased as SGA status became more severe. Compared with the appropriate for gestational age group, the adjusted risk ratios for hospitalization for all causes were 2.5 (95% CI, 1.7-3.6), 1.3 (95% CI, 1.1-1.6), and 1.1 (95% CI, 1.0-1.2) for children who were severely, moderately, and mildly SGA and 1.0 (95% CI, 0.9-1.1), 1.1 (95% CI, 0.9-1.2), and 1.4 (95% CI, 0.9-2.1) for children who were mildly, moderately, and severely large for gestational age, respectively. Severely large for gestational age children also had higher risks of unfavorable neurobehavioral development. These results were supported by spline analyses. CONCLUSIONS Among term infants, the risks of unfavorable child health and neurodevelopment increased with the severity of SGA.

Abstract
Introduction: Late preterm infants (LPIs) are at greater risk for short- and long-term morbidity compared with term infants. However, little is known about whether breastfeeding can reduce the adverse effect of late preterm (LP) birth on various diseases. Therefore, we examined the association of LP birth with the risk of hospitalizations from 6 to 18 months of age, then explored the possible modification of this effect by breastfeeding. Materials and Methods: Data were extracted from a nationwide population-based longitudinal survey in Japan. We restricted our analysis to term and LPIs with information on hospitalization (n = 31,578). Multivariate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated to evaluate the association between LP birth and hospitalization using term birth as the reference. We then examined whether breastfeeding status modified the potential adverse effects of LP birth on each health outcome. Results: LPIs were more likely to be hospitalized for all-cause (aOR, 1.58; 95% CI, 1.35-1.86), respiratory (aOR, 1.52; 95% CI, 1.21-1.92) and gastrointestinal infections (aOR, 1.73; 95% CI, 1.14-2.62) than term infants. While LPIs had a higher risk of hospitalization for all-cause and respiratory infection regardless of breastfeeding status, we did not observe an increased risk of hospitalization for gastrointestinal infection among the exclusively breastfed LPIs, in contrast with increased risk among the non-exclusively breastfed LPIs. Conclusions: We found that LPIs had a higher risk of all-cause and cause-specific hospitalization compared with term infants. Moreover, exclusive breastfeeding probably reduced the adverse effect of LP birth on gastrointestinal infection.
