Iron deficiency (ID) is common in pregnant women and infants, particularly in developing countries. The relation between maternal and neonatal iron status remains unclear. This study considered the issue in a large sample of mother-newborn pairs in rural southeastern China. Hemoglobin (Hb) and serum ferritin (SF) were measured in 3702 pregnant women at ≥37 wk gestation and in cord blood of their infants born at term (37-42 wk gestation). Maternal anemia (Hb <110 g/L) was present in 27.5% and associated with maternal SF <20 μg/L in 86.9%. Only 5.6% of neonates were anemic (Hb <130 g/L) and 9.5% had cord-blood SF <75 μg/L. There were low-order correlations between maternal and newborn iron measures (r = 0.07-0.10 for both Hb and SF; P ≤ 0.0001 due to the large number). We excluded 430 neonates with suggestion of inflammation [cord SF >370 μg/L, n = 208 and/or C-reactive protein (CRP) >5 mg/L, n = 233]. Piecewise linear regression analyses identified a threshold for maternal SF at which cord-blood SF was affected. For maternal SF below the threshold of 13.6 μg/L (β = 2.4; P = 0.001), cord SF was 0.17 SD lower than in neonates whose mothers had SF above the threshold (167 ± 75 vs. 179 ± 80 μg/L). The study confirmed that ID anemia remains common during pregnancy in rural southeastern China. Despite widespread maternal ID, however, iron nutrition seemed to meet fetal needs except when mothers were very iron deficient. The impact of somewhat lower cord SF on iron status later in infancy warrants further study.
Background: This study aims to investigate the impact of protective measures and isolation on intestinal infection in children before and after COVID-19 outbreak in Hangzhou, China.Methods: Data on outpatient visits, intestinal infection visits, and tests of adenovirus or rotavirus from electronic healthcare records were extracted in Children's Hospital of Zhejiang University School of Medicine during the COVID-19 outbreak (January-December, 2020), and be compared with those in 2019 during the same period.Results: We found that pediatric outpatient visits, patients with intestinal infection and its proportion from January to December of 2020 were significantly less than that in the same period of 2019. Furthermore, the numbers of outpatient visits and patients with intestinal infection were the lowest in February and elevated slowly from March to December in 2020. We also found significantly decreased number of completed tests for intestinal viruses, positive cases of adenovirus and rotavirus, positive rate of rotavirus during January-December, 2020. The positive rates of adenovirus from March to September and December of 2020 were significantly lower than the levels of the same period in 2019. The positive rate of rotavirus and adenovirus in all age groups in 2020 is lower than the level of all age groups in 2019.
Conclusions:The outpatient visits and intestinal, rotavirus and adenovirus infections in children significantly decreased during COVID-19 outbreak. Adequate protective measures and isolation in children may help to prevent intestinal virus infections in children.
Aims. The objective of this study was to compare the efficacy of exclusive enteral nutrition (EEN) and corticosteroids in inducing remission in pediatric Crohn's disease (CD) and the effects of the treatment on growth improvements. Methods. Data was retrospectively collected for children and adolescents newly diagnosed with CD in a referral center. Patients who were followed up for more than 2 months with mild to moderate disease were included. Basic demographics, history, physical examination, the pediatric Crohn disease activity index (PCDAI), laboratory findings, endoscopic findings, and adverse effects were recorded. Remission was defined as PCDAI < 10 points. Results. Ten subjects received EEN and 18 patients received corticosteroids. The median follow-up in EEN group and steroid group was 9.2 weeks and 9.6 weeks, respectively. The remission rate in EEN group was significantly higher than that in steroid group (90.0% versus 50.0%, resp., P < 0.05). Growth improvement, which was evaluated by changes in height for age z-score, was more apparent in EEN group than that in steroids group (P < 0.05). No adverse effects were observed in EEN group. Conclusions. In children with mild to moderate CD, EEN is more effective than corticosteroids in improving disease severity and growth deficiency, as well as providing less side effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
