ABSTRACT
Breastmilk contains many important nutrients, anti-inflammatory agents, and immunomodulators. It is the preferred nutrition source for infants. However, the association of the duration of exclusive breastmilk feeding (BMF) with asthma development is unclear. Data on children from the United States who participated in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2014 were obtained. We examined the association between the duration of exclusive BMF and asthma in 6000 children (3 to 6 years old). After calculating the duration of exclusive breastfeeding according to answers to NHANES questionnaires, the estimated duration of exclusive BMF was divided into five categories: never breastfed or BMF for 0 to 2 months after birth; BMF for 2 to 4 months after birth; BMF for 4 to 6 months after birth; and BMF for ≥6 months after birth. The overall prevalence of asthma in children aged 3 to 6 years was approximately 13.9%. The risk of asthma was lower in children with an exclusive BMF duration of 4 to 6 months (aOR, 0.69; 95% CI, 0.48-0.98), after adjustment for potentially confounding factors. Subgroup analysis revealed that children of younger ages (3 to 4 years old) benefited most from the protective effects of exclusive BMF for 4 to 6 months (aOR, 0.47; 95% CI, 0.27, 0.8). We found that exclusive BMF, especially BMF for 4 to 6 months, is associated with a decreased risk of asthma in preschool-age children. The protective effect appeared to be diminished in older children. The potential mechanism needs further investigation.

Mother and newborn skin-to-skin contact (SSC) after birth has numerous protective effects. Although positive associations between SSC and breastfeeding behavior have been reported, the evidence for such associations between early SSC and breastfeeding success was limited in high-income countries. This quasi-experimental intervention design study aimed to evaluate the impact of different SSC regimens on newborn breastfeeding outcomes in Taiwan. In total, 104 healthy mother-infant dyads (52 in the intervention group and 52 in the control group) with normal vaginal delivery were enrolled from 1 January to 30 July 2019. The intervention group received 60 min of immediate SSC, whereas the control group received routine care (early SSC with 20 min duration). Breastfeeding performance was evaluated by the IBFAT and BSES-Short Form. Generalized estimating equations (GEEs) were used to evaluate the effectiveness of the intervention. In the intervention group, the breastfeeding ability of newborns increased significantly after 5 min of SSC and after SSC. The intervention also improved the total score for breastfeeding self-efficacy (0.18 point; p = 0.003). GEE analysis revealed that the interaction between group and time was significant (0.65 point; p = 0.003). An initial immediate SSC regimen of 60 min can significantly improve neonatal breastfeeding ability and maternal breastfeeding self-efficacy in the short term after birth.

Imatinib is a crucial therapeutic strategy against chronic myeloid leukemia. Though superficial edema is a common adverse effect of imatinib, massive fluid retention is rarely reported. Here, we report the case of an adolescent who had tolerated imatinib for a long time, and then presented with massive pleural/pericardial effusion during an episode of Campylobacter jejuni bacteremia. A stepwise and comprehensive survey excluded all other plausible causes of disease. The Naranjo scale was used to assess the probability of an adverse effect of medication, and the score turned out to be 9, indicating severe fluid retention to be a definite reaction to imatinib. Drug discontinuation, antibiotic administration, and invasive procedures improved this condition. After this episode, the patient could tolerate imatinib again, illustrating the transient and reversible nature of this reaction. Since prolonged imatinib usage is crucial for chronic myeloid leukemia control, alertness to drug-related adverse effects is recommended, even if the subject has previously shown a good tolerance to the drug due to various physical conditions, especially physiological stressors, like infection or inflammation.

Transcutaneous bilirubinometer devices are widely applied to assess neonatal hyperbilirubinemia. However, the optimal skin site and timing of transcutaneous bilirubin (TCB) measurements for the strongest correlation with total serum bilirubin (TSB) levels after phototherapy are still unclear. We conducted a retrospective observational study evaluating the correlation of TCB and TSB levels in neonates postphototherapy. The TCB measurements on the forehead and mid-sternum at 0 and 30 min postphototherapy were assessed by using a JM-103 bilirubinometer. Paired TCB and TSB measurements were assessed by Pearson correlation and Bland-Altman plots. We analyzed 40 neonates with 96 TSB and 384 TCB measurements. The TSB level correlated moderately with the forehead TCB level at 30 min postphototherapy (r = 0.65) and less strongly with the midsternum TCB level at 0 min postphototherapy (r = 0.52). The forehead at 30 min after cessation of phototherapy was the best time point and location of TCB measurement for the assessment of neonatal jaundice status. The reliability of TCB measurements varied across skin sites and durations after phototherapy. The effectiveness of TCB measurement to assess neonatal hyperbilirubinemia is much better on covered skin areas (foreheads) 30 min postphototherapy. The appropriate application of transcutaneous bilirubinometers could aid in clinical practice and avoid unnecessary management.
ABSTRACT
BACKGROUND/PURPOSE: To analyze the amount of variation in these risk-adjusted adverse outcomes corresponding to the care of premature births. In addition, hospitals were ranked according to their unadjusted and adjusted rates, and we assessed the degree of concordance between these rankings. Finally, the correlations of hospital-adjusted adverse outcomes were also tested. METHODS: The study utilized the 5-year Taiwan Premature Infant Follow-up Network (TPFN) database in Taiwan from 2014 to 2018, and the sample size was 6482. We calculated the "observed over expected" (OE) ratio every year to form the risk-adjusted adverse outcome rate for each hospital. RESULTS: There was a larger variation in the risk-adjusted rate for NEC and the second-largest variation for IVH. Regarding the concordances between the unadjusted and adjusted ranks, the ranks for mortality had the lowest concordance (coefficient of concordance 0.64), and only a few of the risk-adjusted rates between outcomes were significantly correlated. CONCLUSION: The results of the TPFN show that there is room to improve performance in terms of large variations in NEC and IVH. Furthermore, risk adjustment is important, especially for mortality, since the ranks for mortality have the lowest concordance. Finally, we cannot generate a conclusion regarding whether a hospital is high in quality if we only take 1 or 2 adverse outcomes as profiling measures because only a few of the risk-adjusted rates between outcomes were significantly correlated.

An association between high pre-pregnancy body mass index (BMI) and early breastfeeding cessation has been previously observed, but studies examining the effect of underweight are still scant and remain inconclusive. This study analyzed data from a nationally representative cohort of 18,312 women (mean age 28.3 years; underweight 20.1%; overweight 8.2%; obesity 1.9%) who delivered singleton live births in 2005 in Taiwan. Comprehensive face-to-face interviews and surveys were completed at 6 and 18 months postpartum. BMI status and breastfeeding duration were calculated from the self-reported data in the questionnaires. In the adjusted ordinal logistic regression model, maternal obesity and underweight had a higher odds of shorter breastfeeding duration compared with normal-weight women. The risk of breastfeeding cessation was significantly higher in underweight women than in normal-weight women after adjustments in the logistic regression model (2 m: aOR = 1.11, 95% CI = 1.03-1.2; 4 m: aOR = 1.32, 95% CI = 1.21-1.43; 6 m: aOR = 1.3, 95% CI = 1.18-1.42). Our findings indicated that maternal underweight and obesity are associated with earlier breastfeeding cessation in Taiwan. Optimizing maternal BMI during the pre-conception period is essential, and future interventions to promote and support breastfeeding in underweight mothers are necessary to improve maternal and child health.

Epidemiological studies have shown that maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) are associated with increased risk of perinatal outcomes. However, the evidence of such associations in Asian populations is limited. We conducted a secondary data analysis to investigate the relationships of prepregnancy BMI and GWG with the risks of adverse perinatal outcomes, including gestational diabetes (GDM), gestational hypertension (GHTN), preeclampsia, cesarean delivery, preterm birth, low birth weight (LBW), and macrosomia. We categorized prepregnancy BMI by the WHO classification and GWG by the Institute of Medicine guidelines. We performed adjusted logistic regression models to estimate the odds ratios of adverse perinatal outcomes. A total of 19,052 women were included; prepregnancy overweight and obesity were associated with a greater risk of GDM, GHTN, preeclampsia, cesarean delivery, preterm birth, and macrosomia. Women with excessive GWG had a greater risk of GHTN, preeclampsia, cesarean delivery, and macrosomia. In conclusion, regardless of the range of GWG during pregnancy, maternal prepregnancy BMI is significantly associated with the risk of adverse perinatal outcomes in Taiwan. Public health attention regarding obesity reduction before conception and prenatal counseling for optimal GWG is needed to mitigate the risk of poor perinatal outcomes.

OBJECTIVES: Critical illnesses caused by undiagnosed genetic conditions are challenging in PICUs. Whole-exome sequencing is a powerful diagnostic tool but usually costly and often fail to arrive at a final diagnosis in a short period. We assessed the feasibility of our whole-exome sequencing as a tool to improve the efficacy of rare diseases diagnosis for pediatric patients with severe illness. DESIGN: Observational analysis. METHOD: We employed a fast but standard whole-exome sequencing platform together with text mining-assisted variant prioritization in PICU setting over a 1-year period. SETTING: A tertiary referral Children's Hospital in Taiwan. PATIENTS: Critically ill PICU patients suspected of having a genetic disease and newborns who were suspected of having a serious genetic disease after newborn screening were enrolled. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Around 50,000 to 100,000 variants were obtained for each of the 40 patients in 5 days after blood sampling. Eleven patients were immediately found be affected by previously reported mutations after searching mutation databases. Another seven patients had a diagnosis among the top five in a list ranked by text mining. As a whole, 21 patients (52.5%) obtained a diagnosis in 6.2 ± 1.1 working days (range, 4.3-9 d). Most of the diagnoses were first recognized in Taiwan. Specific medications were recommended for 10 patients (10/21, 47.6%), transplantation was advised for five, and hospice care was suggested for two patients. Overall, clinical management was altered in time for 81.0% of patients who had a molecular diagnosis. CONCLUSIONS: The current whole-exome sequencing algorithm, balanced in cost and speed, uncovers genetic conditions in infants and children in PICU, which helps their managements in time and promotes better utilization of PICU resources.

BACKGROUND: Soluble fms-like tyrosine kinase receptor-1 (sFlt-1)/placental growth factor (PlGF) ratio has been studied extensively as a predictive marker for pre-eclampsia. However, its usefulness for predicting neonatal outcomes remains unknown. This study aimed to evaluate the association of sFlt-1/PlGF ratio with pregnancy outcomes, neonatal morbidities and short-term postnatal growth patterns in pregnant women and their babies. METHODS: sFlt-1 and PlGF were measured in women with fetal intrauterine growth retardation (IUGR) or pre-eclampsia during gestational age (GA) of 16-36 weeks. These women were classified into high- and low-ratio groups with a sFlt-1/PlGF cut-off ratio of 85. The maternal and neonatal outcomes were retrospectively reviewed and compared between the two groups. RESULTS: A total of 25 pregnant women were recruited. Thirteen of them had a sFlt-1/PlGF ratio over 85 and twelve had a ratio of less than 85. The median duration from elevation of sFlt-1/PlGF to delivery was 4.5 weeks. Women in the high SFlt-1/PlGF ratio group had higher rates of intrauterine fetal demise (2/13 vs. 0/12) and early termination (1/13 vs. 0/12). The surviving offspring in this group had a higher incidence of preterm birth (GA: 31.4 ± 2.9 weeks vs. 37.3 ± 1.3 weeks, p < 0.001), lower birth weight (1142 ± 472 g vs. 2311 ± 236 g, p < 0.001), higher incidence of respiratory distress syndrome (6/10 vs. 0/12, p = 0.002) and bronchopulmonary dysplasia (4/10 vs. 0/12, p = 0.01). However, the percentile of body weight, height and head circumference at 28 days of age, 56 days of age and the corrected age of 6 months were comparable between groups. CONCLUSIONS: High sFlt-1/PlGF ratio in pregnant women is associated with poor pregnancy and neonatal outcomes. Therefore, the monitoring of sFlt-1/PlGF ratio in pregnant women with fetal IUGR and timely management for placenta-associated diseases are recommended.

BACKGROUND: Acute kidney injury (AKI) is common in preterm infants and is associated with high mortality and morbidity. New biomarkers for the early detection of AKI have been identified. Specifically, urinary neutrophil gelatinase-associated lipocalin (uNGAL) is a new and powerful biomarker for AKI and sepsis. Our study evaluated the reference range of uNGAL in healthy neonates in Taiwan. METHODS: This study examined 24 preterm and 38 term infants without clinical complications. Urine samples were collected and the uNGAL values were measured at postnatal age (PNA) 3 days, 7 days, 14 days, and 21 days in the preterm infants and at PNA 3 days in the term infants. The uNGAL values were tested using enzyme-linked immunosorbent assay. RESULTS: The median uNGAL values in the preterm infants at PNA 3 days, 7 days, 14 days, and 21 days were 41.52 ng/mL, 35.82 ng/mL, 43.79 ng/mL, and 30.85 ng/mL, respectively. The median value at PNA 3 days in the term infants was 88.1 ng/mL. No significant differences associated with gestational age, birth body weight, or PNA were observed among the preterm infants. However, the uNGAL values in the female term infants were higher than those in the male term infants (p = 0.003). CONCLUSION: This study presents preliminary data on uNGAL levels in neonates in Taiwan. A large-scale study investigating the correlations between uNGAL and with gestational age, birth body weight, sex, and PNA is recommended.
