ABSTRACT

An early diagnosis and intervention for congenital cytomegalovirus infection can reduce long-term disability; however, the introduction of universal neonatal screening has been controversial worldwide. The present study clarified the outcome of a targeted screening protocol for detecting congenital cytomegalovirus infection based on suggestive perinatal conditions. In addition, the positive rate was compared to those from the reported studies and the validity of the targeted screening criteria was discussed. A total of 2121 newborn infants were admitted to our hospital between October 2018 and October 2021. Cytomegalovirus DNA was examined by the isothermal nucleic acid amplification method for urine samples from newborns with any of the following: microcephaly, abnormal ultrasound findings in the brain and visceral organs, repeated failure in neonatal hearing screening, suspicious maternal cytomegalovirus infection during pregnancy, and other abnormal findings suggestive of congenital cytomegalovirus infection. Among 2121 newborns, 102 (4.8%) were subject to the urine cytomegalovirus DNA test based on the abovementioned criteria. Of them, three were cytomegalovirus DNA-positive. According to the protocol, the cytomegalovirus DNA-positive rates were 0.14% among the total enrollment of 2121 newborns and 2.9% (3/102) among the targeted newborns. This protocol may overlook congenital cytomegalovirus infection that is asymptomatic or exhibits inapparent clinical manifestations only at birth; however, it is feasible and helps lead to the diagnosis of congenital cytomegalovirus infection that may otherwise be overlooked.

ABSTRACT

AIM: The effect that intrauterine or extrauterine growth restriction (EUGR) had on the build of very low birthweight (VLBW) infants was investigated before Japanese children started school. METHOD: Between 2005 and 2017, the National Hospital Organization, Saga, Japan, carried out preschool checks on 322 children born with a VLBW at approximately six years of age. Growth restriction was defined as being born small for gestational age (SGA) or EUGR if they were born at term. The prevalence of short stature, thinness and obesity was determined, and associations between SGA or EUGR and subsequent body build were investigated. RESULTS: In this study, 77 of 322 (23.9%) infants were SGA and 153 of 322 (47.5%) were EUGR: 14 of 77 (18.2%) SGA infants caught up in growth to the 169 non-EUGR infants, while 90 of 245 (36.7%) appropriate for gestational age infants subsequently demonstrated EUGR. There were 38 (11.8%) short stature, 38 (11.8%) thin and six (1.9%) obese subjects in the total cohort and growth hormone deficiencies in nine (2.8%) cases. We found significant associations between EUGR and both short stature and thinness. CONCLUSION: Extrauterine growth restriction was significantly associated with short stature and thinness in VLBW infants at around six years, irrespective of the degree of SGA.

ABSTRACT

AIM: To clarify the influence of intra- and extra-uterine growth on subsequent psychomotor development in very-low-birth-weight (VLBW) infants. METHODS: Two hundred and eighty VLBW infants (28.4 ±â€¯2.6 weeks, 1000 ±â€¯294 g) were enrolled. Psychomotor development was determined at 37.1 ±â€¯2.1 months after birth using the Kyoto Scale of Psychological Development (KSPD), which includes Postural-Motor (P-M), Cognitive-Adaptive (C-A) and Language-Social (L-S) subscales. Subjects were divided into two groups based on whether each developmental quotient (DQ) was ≥85, and the perinatal variables that contributed to a DQ of ≥85 (for each DQ) were determined. The twelve variables that were evaluated included the z scores for body weight (zBW), body length (zBL), head circumference (zHC), which were obtained at birth and at term. RESULTS: The median P-M, C-A, L-S values and total DQ were 92, 83, 81 and 83, respectively, and the percentage of patients with a DQ of ≥85 were 53%, 44%, 35% and 39%, respectively. A multivariate analysis revealed significant associations between the following variables and the DQs: P-M ≥ 85, GA [odds ratio; OR = 1.11] and zBL at term [OR = 1.26]; C-A ≥ 85, male gender [OR = 0.30], GA [OR = 1.14] and zHC at term [OR = 1.84]; L-S ≥ 85, male gender [OR = 0.55], GA [ OR = 1.20] and zHC at term [OR = 1.45]; total DQ ≥ 85, male gender [OR = 0.39], GA [OR = 1.19] and zBL at term [OR = 1.69]. CONCLUSION: In addition to less prematurity and female gender, a longer body length and larger head circumference at term were important indicators that influenced better psychomotor development in VLBW infants at three years of chronological age.
