Chaudhary P, Priyadarshi M, Singh P, Chaurasia S, Chaturvedi J, Basu S. Effects of delayed cord clamping at different time intervals in late preterm and term neonates: a randomized controlled trial. Eur J Pediatr 2023; 182:3701-3711. [PMID: 37278737 PMCID: PMC10243262 DOI: 10.1007/s00431-023-05053-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/26/2023] [Accepted: 06/02/2023] [Indexed: 06/07/2023]
Abstract
Delayed cord clamping (DCC) at delivery has well-recognized benefits; however, current scientific guidelines lack uniformity in its definition. This parallel-group, three-arm assessor-blinded randomized controlled trial compared the effects of three different timings of DCC at 30, 60, and 120 s on venous hematocrit and serum ferritin levels in late preterm and term neonates not requiring resuscitation. Eligible newborns (n = 204) were randomized to DCC 30 (n = 65), DCC 60 (n = 70), and DCC 120 (n = 69) groups immediately after delivery. The primary outcome variable was venous hematocrit at 24 ± 2 h. Secondary outcome variables were respiratory support, axillary temperature, vital parameters, incidences of polycythemia, neonatal hyperbilirubinemia (NNH), need and duration of phototherapy, and postpartum hemorrhage (PPH). Additionally, serum ferritin levels, the incidence of iron deficiency, exclusive breastfeeding (EBF) rate, and anthropometric parameters were assessed during post-discharge follow-up at 12 ± 2 weeks. Over one-third of the included mothers were anemic. DCC 120 was associated with a significant increase in the mean hematocrit by 2%, incidence of polycythemia, and duration of phototherapy, compared to DCC30 and DCC60; though the incidence of NNH and need for phototherapy was similar. No other serious neonatal or maternal adverse events including PPH were observed. No significant difference was documented in serum ferritin, incidences of iron deficiency, and growth parameters at 3 months even in the presence of a high EBF rate. Conclusion: The standard recommendation of DCC at 30-60 s may be considered a safe and effective intervention in the busy settings of low-middle-income countries with a high prevalence of maternal anemia. Trial registration: Clinical trial registry of India (CTRI/2021/10/037070). What is Known: • The benefits of delayed cord clamping (DCC) makes it an increasingly well-accepted practice in the delivery room. • However, uncertainty continues regarding the optimal timing of clamping; this may be of concern both in the neonate and the mother. What is New: • DCC at 120 s led to higher hematocrit, polycythemia and longer duration of phototherapy, without any difference in serum ferritin, and incidence of iron deficiency. • DCC at 30-60 s may be considered a safe and effective intervention in LMICs.

Abstract
INTRODUCTION Undiagnosed and untreated hyperbilirubinemia in infants may result in Kernicterus Spectrum Disorder and poor prognoses. Rhesus incompatibility and glucose-6-phosphate dehydrogenase (G6PD) deficiency are among the known causes of infantile jaundice. This study was designed to define the severity and prognosis in jaundiced infants with Rh incompatibility or G6PD deficiency. METHODS A total of 144 term, 2- 14 days old jaundiced infants (bilirubin > 20 mg/dl) with Rh incompatibility(85 infant) or G6PD deficiency(59 infant) were included in this cohort study with 24-month follow-up through available sampling at Ghaem hospital between 2015 and 2022. Denver II test was used at 6, 12, 18, and 24-month ages after discharge. Infants with Rh incompatibility or G6PD deficiency were assigned into two groups of favorable and poor prognosis. Following that, the bilirubin levels of these infants were compared at the time of admission. RESULTS The bilirubin level in G6PD deficient infants with poor prognoses (37.96 ± 9.25 mg/dl) and neonates with Rh incompatibility (36.23 ± 5.08 mg/dl) almost was the same (P = 0.232). 40 babies (47%) caused by Rh incompatibility and 33 (56%) babies caused by G6PD deficiency had a poor prognosis (P = 0.465). Average bilirubin in babies with RH incompatibility with favorable prognosis is 21.8 and poor prognosis is 36.2 mg/dl. In infants with G6PD deficiency, it was 24 mg/dl with favorable prognosis and 38 mg/dl with poor prognosis (P < 0.0001). The severity of hyperbilirubinemia had a significant role in the prognosis of infants in both groups (P < 0.0001). CONCLUSION The two-year prognoses of hyperbilirubinemia caused by G6PD deficiency are as poor as that of Rh incompatibility. The severity of hyperbilirubinemia had a significant role in the prognosis of infants in both groups.Exchange transfusion in cases with bilirubin < 25 mg/dl can improve the prognosis in both groups, especially in infants with Rh incompatibility.

Abstract
Introduction Jaundice is a common problem that affects up to 50-60% of full-term babies and 80% of preterm babies. It is a benign condition, but sometimes it can cause profound complications and eventually death. Identifying the treatment outcome of jaundice and the factors affecting it is crucial to preventing the death associated with it. Objective To determine the treatment outcome of jaundice and its associated factors among neonates treated in neonatal intensive care unit of comprehensive and specialized hospitals of SNNPR, Ethiopia, 2022. Methods An institution-based retrospective follow up study was conducted from April 2018 to April 2022. The data was checked for completeness and then entered into Epi-data version 4.6 and exported to STATA version 17. The results were presented in frequencies and percentages for categorical variables as well as mean and median for continuous variables. A binary logistic regression model was used to estimate the effect of an independent variable and the outcome variable. Results A total of 423 charts were reviewed, and 416 (98%) were included in the final analysis. Almost 91.3% (95% CI: 88.2, 93.7) of neonates had improved. Factors significantly associated with the treatment outcome were: residence (AOR = 0.36, 95% CI: 0.2, 0.8); origin of admission (AOR = 0.35, 95% CI: 0.2, 0.8); gestational age (AOR = 0.26, 95% CI: 0.1, 0.8); and total serum bilirubin level (AOR = 0.40, 95% CI: 0.2, 0.9). Conclusion and Recommendation Improvement was lower compared to other low and middle-income countries; more emphasis should be given to improving treatment outcomes in hospitals.

Abstract
Thrombocytopenia is a common laboratory abnormality encountered in critically ill neonates. The broad differential for thrombocytopenia, and its association with potentially severe neonatal pathology, often presents a diagnostic dilemma prompting extensive evaluation. Hemolysis due to red cell enzymopathies is a rare cause of neonatal thrombocytopenia that is typically brief and self-limiting. Here, we present a case of thrombocytopenia, refractory to transfusion, associated with anemia and hyperbilirubinemia in a neonate with pyruvate kinase deficiency (PKD) arising from compound heterozygous PKLR mutations. The nature of the thrombocytopenia in this patient created considerable diagnostic uncertainty, which was ultimately resolved by whole-exome sequencing. This case emphasizes that inherited red cell defects, such as PKD, are important to consider in cases of neonatal thrombocytopenia.

Front Public Health 2023; 11:1212667. [PMID: 37538268 PMCID: PMC10395091 DOI: 10.3389/fpubh.2023.1212667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Accepted: 06/26/2023] [Indexed: 08/05/2023] Open
Abstract
Purpose Although neonatal jaundice is a ubiquitous and predominantly benign phenomenon, the risk of neurotoxicity exists in a number of infants with unconjugated hyperbilirubinemia. Plotting bilirubin values on nomograms enables clinicians to employ an anticipatory and individualized approach with the goal of avoiding excessive hyperbilirubinemia and preventing acute bilirubin encephalopathy and its progression to kernicterus. We aimed to construct nomograms for White term infants based on transcutaneous bilirubin (TcB) measurements using a JM-105 device. Methods TcB measurements were taken in infants at ages ranging from 0 to 96 postnatal hours. We then constructed hour-specific TcB nomograms from forehead and sternum measurements in infants who did not require subsequent phototherapy. Results We included 2,981 TcB measurements taken on the forehead and 2,977 measurements taken on the sternum in 301 White term newborn infants. We assessed the predictive abilities of the nomograms at six postnatal time intervals using receiver operating characteristic curves. The areas under the curves indicated reasonable prediction of hyperbilirubinemia requiring phototherapy, except for the forehead measurement taken within the first 12 h of life. Sensitivity tended to rise as postnatal age increased. Conclusion The nomograms illustrate dermal bilirubin dynamics in White term neonates during the first 4 days of life. They may be useful tools to predict individualized risk of hyperbilirubinemia requiring treatment, and to plan optimal follow-up of infants at risk of bilirubin neurotoxicity.

Abstract
Objective Glucose 6-phosphate dehydrogenase (G6PD) deficiency increases the risk of neonatal hyperbilirubinemia. The aim of this study is to evaluate the risk factors associated with hyperbilirubinemia in infants from the western part of Guangdong Province, and to assess the contribution of G6PD deficiency to neonatal jaundice. Methods The term infants with neonatal hyperbilirubinemia in People's Hospital of Yangjiang from June 2018 to July 2022 were recruited for the retrospective analysis. All the infants underwent quantitative detection of the G6PD enzyme. The etiology was determined through laboratory tests and clinical manifestations. Results Out of 1,119 term infants, 435 cases presented with jaundice. For the etiology analysis, infection was responsible for 16.09% (70/435), G6PD deficiency accounted for 9.66% (42/435), of which 3 were complicated with acute bilirubin encephalopathy), bleeding accounted for 8.05% (35/435), hemolytic diseases accounted for 3.45% (15/435), and breast milk jaundice accounted for 2.53% (11/435). One case (0.23%) was attributed to congenital hypothyroidism, multiple etiologies accounted for 22.3% (97/435), and 35.63% (155/435) were of unknown etiology. Of the jaundiced infants, 19.54% (85/435) had G6PD deficiency, while only 10.23% (70/684) of non-jaundiced infants had G6PD deficiency; this difference was found to be statistically significant (P < 0.001). Furthermore, the hemoglobin levels in the jaundiced infants with G6PD deficiency (146.85 ± 24.88 g/L) were lower than those without G6PD deficiency (156.30 ± 22.07 g/L) (P = 0.001). 65 jaundiced infants with G6PD deficiency underwent G6PD mutation testing, and six different genotypes were identified, including c.95A > G, c.392G > T, c.1024C > T, c.1311C > T, c.1376G > T, c.1388G > A, c.871G > A/c.1311C > T, c.392G > T/c.1388G > A, and c.1376G > T/c.1311C > T.65iciency. Conclusion In newborns in Yangjiang, G6PD deficiency, infection, and neonatal hemolytic disease were identified as the main causes of hyperbilirubinemia and acute bilirubin encephalopathy. Specifically, Hemolytic factors in infants with G6PD deficiency may lead to reduced hemoglobin and increased bilirubin levels in jaundiced infants.

Abstract
BACKGROUND One of the most prevalent illnesses in neonates that needs care and treatment is neonatal jaundice. Several drugs are used as pharmacological modalities for treating hyperbilirubinemia, like intravenous immunoglobulin, D-penicillamine, metalloporphyrin, phenobarbital, zinc sulfate and clofibrate. Previous studies suggest the usefulness of fenofibrate in the treatment of hyperbilirubinemia. OBJECTIVES The study aims at assessing the effectiveness of oral fenofibrate in the treatment of indirect neonatal hyperbilirubinemia in full-term neonates. METHOD This is a quasi-experimental study that was conducted at Heevi Pediatrics Teaching Hospital in Duhok, which is located in the Kurdistan Region of Iraq. It involved term infants who had jaundice. The neonates who were eligible for the study were randomly assigned to one of two groups: the intervention group or the control group. Both groups were treated with conventional phototherapy. Fenofibrate was administered in a single oral dose of 10 mg/kg to the participants in the intervention group. Throughout the entirety of the treatment, levels of total serum bilirubin were compared and contrasted between the two groups. RESULTS After 12 h of treatment, a statistically significant difference (p-value = 0.001) was seen in the serum bilirubin levels between the two groups. The difference in serum bilirubin levels became significantly progressively pronounced after 24, 48, and 72 h. The average time of discharge was 63.6 h for the intervention group and 90.9 h for the control group, and this difference was statistically significant (p-value < 0.001). CONCLUSIONS The time it takes to lower high bilirubin levels in neonates may be shortened by combining conventional phototherapy with a single oral dosage of 10 mg/kg fenofibrate. Consequently, these neonates will experience a shorter hospitalization and an accelerated discharge from the hospital.

Abstract
Glucose-6-phosphate dehydrogenase (G6PD) deficiency and polymorphism in uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1) were associated with significant neonatal hyperbilirubinemia (NHB) and increased risk for kernicterus. However, quantitative screening tests for G6PD enzyme activity proved unsatisfactory in estimating the risk for significant NHB, especially in heterozygous females that could present phenotype overlap between normal homozygotes, heterozygotes, and deficient homozygotes, resulting in a continuum of intermediate G6PD activity. OBJECTIVE To examine the association of genotype and phenotype in newborns with decreased G6PD activity and its relation to NHB. STUDY DESIGN Quantitative G6PD enzyme activities were measured on umbilical cord blood samples. After accepting parental consent, samples were analyzed for G6PD mutations and UGT1A1 gene polymorphisms (number of TA repeats in the UGT1A1 promoter). The associations to quantitative G6PD activity and bilirubin levels were assessed. RESULTS 28 females and 27 males were studied. The Mediterranean mutation (NM_001360016.2(G6PD): c.563C>T (p.Ser188Phe)) was responsible for most cases of G6PD deficiency (20 hemizygous males, 3 homozygous and 16 heterozygous females). The association between this mutation, decreased G6PD activity and higher bilirubin levels was confirmed. Heterozygosity to 6/7 TA repeats in the UGT1A1 promoter was associated with increased NHB, especially in female newborns with G6PD deficiency. However, it seems that the interaction between G6PD deficiency, UGT1A1 promoter polymorphism, and NHB is more complex, possibly involving other genetic interactions, not yet described. Despite genotyping females with G6PD deficiency, the overlap between the upper range of borderline and the lower range of normal G6PD activity could not be resolved. CONCLUSIONS The results of this study highlight the possibility for future implementation of molecular genetic screening to identify infants at risk for significant NHB, especially UGT1A1 polymorphism in heterozygous females with borderline G6PD deficiency. However, further studies are needed before such screening could be applicable to daily practice.

Abstract
Neonatal hyperbilirubinaemia requiring phototherapy treatment is a common problem impacting the length of hospital stay and rates of hospital readmission. Previous guidelines included guidance for initiating phototherapy treatment but not for discontinuing phototherapy treatment during initial newborn admission.In response to dissatisfaction from trainees, staff and families regarding the variable approach to discontinuing phototherapy among attending nursery providers, we used quality improvement methodologies to increase utilisation of a rebound hyperbilirubinaemia calculator as a more consistent method for guiding the timing of phototherapy discontinuation. The aim was to increase utilisation of the rebound hyperbilirubinaemia calculator for newborns treated with phototherapy in two newborn nurseries to >90% within 2 years.Sequential interventions focused on increasing provider awareness of the rebound hyperbilirubinaemia calculator and making the calculator simple to access and use.At the university medical centre nursery, the use of the calculator increased from 8.7% to 100%, exceeding the project goal. In the community hospital nursery, there was a statistically significant increase in the rate of utilisation from 3.7% to 79.4%, but this fell slightly below the goal of >90%.Electronic Health Record integration, along with education and addition of prompts to providers, increased utilisation of a rebound hyperbilirubinaemia calculator as a consistent approach for guiding decisions about discontinuing phototherapy treatment in newborns.

Abstract
Two hospitals noted increased newborn hyperbilirubinemia coinciding with an undisclosed total serum bilirubin (TSB) assay change. Clinicians rapidly applied quality improvement methodologies to ascertain increased jaundice evaluations, readmissions, and possible safety issues. Methods In January 2020, 2 hospitals (A and B) transitioned to a new method of measuring TSB using a new clinical chemistry analyzer (Siemens Atellica CH), which measured TSB by vanadate oxidase assay instead of the previous diazo assay. Five affiliated hospitals (C-G) continued to utilize the diazo assay. This natural experiment led to a comparison of data across the 7 hospitals. We analyzed: (1) TSB levels, (2) hospital hyperbilirubinemia readmissions, and (3) paired TSB measurements comparing the diazo assay and vanadate oxidase method. Results Compared to the 2019 baseline, Hospitals A and B had a significant increase in TSBs ≥17.0 mg/dl and TSBs ≥20 mg/dl in 2020; Hospitals C-G did not. Readmissions for phototherapy significantly increased in hospitals A and B in 2020 compared to 2019. Paired blood samples showed bias-elevated TSBs by vanadate assay compared to the diazo method. By 2021, the laboratory resumed processing TSB samples by diazo assay, and the frequency of elevated TSBs and hyperbilirubinemia readmissions returned to 2019 levels. Conclusions Factitious TSB elevation related to an assay change significantly increased newborn hyperbilirubinemia evaluations and phototherapy readmissions. Imbedded quality improvement methodologies of careful structure, process, and outcomes review hastened resolution.

J Clin Exp Hepatol 2023; 13:666-681. [PMID: 37440934 PMCID: PMC10333952 DOI: 10.1016/j.jceh.2022.11.011] [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: 09/17/2022] [Accepted: 11/20/2022] [Indexed: 11/27/2022] Open
Abstract
Objective Early discharge puts neonates at risk of delayed detection of jaundice and resulting neurological injury. In these neonates, we can use cord bilirubin to make predictions. In this meta-analysis, we assessed the diagnostic accuracy of cord bilirubin in predicting the need for phototherapy (AAP-2004 or NICE-2010 charts). Methods We searched the databases of PubMed, Embase, Cochrane Library, Google Scholar, and Index Medicus for Southeast Asian Region. We included all observational studies that assessed the diagnostic accuracy of cord bilirubin. A bivariate model was used to pool the data in prespecified range of cord bilirubin levels (<1.5 mg/dl, 1.5-2.0 mg/dl, 2.0-2.5 mg/dl, 2.5-3.0 mg/dl, and >3.0 mg/dl). Data were pooled separately for studies including all neonates (no risk stratification), high-risk neonates (Rh and/or ABO incompatibility only), and low-risk neonates (excluded Rh and ABO incompatibility). Results Of the 1990 unique records, we studied 153 full texts and included 54 studies in the meta-analysis. For all the three groups of studies, the highest diagnostic odds ratio was noted for a cord bilirubin cut-off of 2.5-3.0 mg/dl (all neonates: 22.5, 95% CI: 21.1, 22.9; high-risk neonates: 75.5, 95% CI: 63, 85.7; low-risk neonates: 91.9; 95% CI: 64, 134.14). Using the same cut-off, the studies including all neonates without risk stratification had a pooled sensitivity of 0.31 (95% CI: 0.18, 0.47) and a pooled specificity of 0.98 (0.96, 0.99) in predicting the need for phototherapy. In studies on high-risk neonates, the pooled sensitivity was 0.8 (0.39, 0.96) and pooled specificity was 0.95 (0.78, 0.99). In studies on low-risk neonates, the pooled sensitivity was 0.74 (0.39, 0.93) and pooled specificity of 0.97 (0.91, 0.99). We noted significant heterogeneity and a high risk of bias in the index test's conduct. Conclusion A cord bilirubin cut-off of 2.5-3 mg/dl has good diagnostic accuracy in predicting the need for phototherapy in neonates. Registration number CRD42020196216.

Abstract
BACKGROUND Infants born between 34 weeks and 36 weeks and 6 days of gestation are defined as late preterm infants (LPIs), and they account for approximately 74% of all premature births. Preterm birth (PB) remains the leading cause of infant mortality and morbidity worldwide. AIM To analyse short-term morbidity and mortality and identify predictors of adverse outcomes in late preterm infants. PATIENTS AND METHODS In this retrospective study, we evaluated adverse short-term outcomes of LPIs admitted to the Intensive Care Unit (ICU), Clinic for Children's Diseases, University Clinical Center Tuzla, between 01.01.2020 and 31.12.2022. The analysed data included sex, gestational age, parity, birth weight, Apgar score (i.e., assessment of vitality at birth in the first and fifth minutes after birth), and length of hospitalization in NICU, as well as short-term outcome data. Maternal risk factors we observed were: age of mother, parity, maternal morbidity during pregnancy, complications and treatment during pregnancy. LPIs with major anatomic malformations were excluded from the study. Logistic regression analysis was used to identify risk factors for neonatal morbidity among LPIs. RESULTS We analysed data from 154 late preterm newborns, most of whom were male (60%), delivered by caesarean Sect. (68.2%) and from nulliparous mothers (63.6%). Respiratory complications were the most common outcome among all subgroups, followed by CNS morbidity, infections and jaundice requiring phototherapy. The rate of almost all of the complications in the late-preterm group decreased as gestational age increased from 34 to 36 weeks. Birth weight (OR: 1,2; 95% CI: 0,9 - 2,3; p = 0,0313) and male sex (OR: 2,5; 95% CI: 1,1-5,4; p = 0,0204) were significantly and independently associated with an increased risk for respiratory morbidity, and gestational weeks and male sex were associated with infectious morbidity. None of the risk factors analysed herein were predictors of CNS morbidity in LPIs. CONCLUSION A younger gestational age at birth is associated with a greater risk of short-term complications among LPIs, thus highlighting the need for increased knowledge about the epidemiology of these late preterm births. Understanding the risks of late preterm birth is critical to optimizing clinical decision-making, enhancing the cost-effectiveness of endeavours to delay delivery during the late preterm period, and reducing neonatal morbidity.

Arch Pediatr 2023:S0929-693X(23)00084-2. [PMID: 37321947 DOI: 10.1016/j.arcped.2023.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 04/03/2023] [Accepted: 05/21/2023] [Indexed: 06/17/2023]
Abstract
BACKGROUND Free bilirubin jaundice is a frequent pathology in the neonatal period. The major complication is neurological toxicity, the most severe form of which is kernicterus. Overall, 5%-10% of jaundiced neonates require treatment. The first-line treatment is phototherapy, with intensive phototherapy being the gold standard. Other equipment is also available, including the BiliCocoon Bag®. It is a safe and controlled therapy that can be performed in the mother's room in the maternity ward, thereby avoiding separation and allowing for breast- or bottle-feeding during treatment. It is easy to install and does not require protective glasses, thus no scope or hospitalization. In our maternity ward, all neonates requiring intensive phototherapy are hospitalized in the neonatology ward. OBJECTIVE The objective of our study was to evaluate the number of avoided hospitalizations in neonatology for free bilirubin jaundice since the introduction, according to a strict protocol, of the BiliCocoon Bag® device. MATERIAL AND METHOD This was a single-center retrospective cohort study using data of newborns usually collected as part of standard care. Children born in our maternity ward during an 18-month period (August 1, 2020 to January 31, 2022) were included. Causes of jaundice, age at the beginning and mode of treatment, number of sessions for each device, and length of stay were compared. Results are presented as number and percentage with median (25th-75th) or mean (extremes) values for categorical and continuous variables, respectively. A t-test was used to compare the means of the independent groups. RESULTS A total of 316 newborns were included. Physiological jaundice was the main cause of jaundice. The median age for the first phototherapy treatment was 54.5 h (30-68). The 316 neonates needed 438 phototherapy sessions: 235 (74%) neonates required only one phototherapy session, 85 (36%) of them were treated with the BiliCocoon Bag®. For the 81 children who needed two or more phototherapy sessions, 19 children (23.5%) were treated by tunnel phototherapy and then the BiliCocoon Bag®, and eight children (10%) by BiliCocoon Bag® alone. The BiliCocoon Bag® enabled a relative reduction in the hospitalization rate of 38% and avoided hospitalization for approximately one third of the newborns treated. The BiliCocoon Bag® failure rate was 3.6% and the average length of stay was comparable between the two types of treatment. CONCLUSION Following a strict protocol of use, the BiliCocoon Bag® is a reliable method and a good alternative to intensive phototherapy for newborns in the maternity ward, as it avoids hospitalization and mother-infant separation.

Abstract
Historically, blood for admission laboratory studies in neonates was obtained through direct neonatal phlebotomy. Over the past decade there has been an increase in studies evaluating the validity and clinical impact of using a cord blood sample for many admission laboratory studies. This article reviews various studies that together have shown that using cord blood samples for admission testing in neonates is both acceptable and beneficial.

Abstract
Recent findings indicated aberrant epigenetic control of the central nervous system (CNS) development in hyperbilirubinemic Gunn rats as an additional cause of cerebellar hypoplasia, the landmark of bilirubin neurotoxicity in rodents. Because the symptoms in severely hyperbilirubinemic human neonates suggest other regions as privileged targets of bilirubin neurotoxicity, we expanded the study of the potential impact of bilirubin on the control of postnatal brain development to regions correlating with human symptoms. Histology, transcriptomic, gene correlation, and behavioral studies were performed. The histology revealed widespread perturbation 9 days after birth, restoring in adulthood. At the genetic level, regional differences were noticed. Bilirubin affected synaptogenesis, repair, differentiation, energy, extracellular matrix development, etc., with transient alterations in the hippocampus (memory, learning, and cognition) and inferior colliculi (auditory functions) but permanent changes in the parietal cortex. Behavioral tests confirmed the presence of a permanent motor disability. The data correlate well both with the clinic description of neonatal bilirubin-induced neurotoxicity, as well as with the neurologic syndromes reported in adults that suffered neonatal hyperbilirubinemia. The results pave the way for better deciphering the neurotoxic features of bilirubin and evaluating deeply the efficacy of new therapeutic approaches against the acute and long-lasting sequels of bilirubin neurotoxicity.

Abstract
The aim of this study was to define risk factors for jaundice and anemia in newborns with a positive direct antiglobulin test (DAT) and/or with an incompatible crossmatch due to ABO incompatibility between mother and newborn. ABO incompatibility has become a more significant cause of hemolytic disease of the fetus and newborn since the introduction of effective anti-D prophylaxis. The condition is common and, if clinically significant at all, causes only mild jaundice, which can be treated with phototherapy (PT). However, rare and serious presentations, requiring transfusion therapy, have been noted. Clinical, laboratory, and immunohematologic data were collected retrospectively from medical records of ABO-incompatible newborns and their mothers over a 5-year period (2016-2020) from University Hospital Centre Zagreb. Two groups of newborns were compared: those who needed medical intervention because of hyperbilirubinemia or anemia and those who did not. Within the group of newborns requiring intervention, we also compared those with A and B blood groups. Over the 5-year period, 72 of 184 (39%) newborns required treatment. The treatment was PT in 71 (38%) newborns and erythrocyte transfusion in 2 (1%). In 112 (61%) newborns, ABO incompatibility was an accidental finding while performing blood group typing; these newborns did not require any therapy. In conclusion, we found a statistical, but not clinically significant, difference between the groups of treated and untreated newborns, related to the mode of delivery and DAT positivity within hours of delivery. There were no statistically significant differences in characteristics between the groups of treated newborns, except for two newborns with blood group A who received erythrocyte transfusions.

Abstract
BACKGROUND Neonatal hyperbilirubinemia (NH) is a major cause of hospitalization after birth. Previous studies indicated that vitamin D deficiency might play an important role in NH susceptibility, but the results were controversial. Meanwhile, there has been limited description of the association between vitamin D related genes single nucleotide polymorphisms (SNP) and NH susceptibility. We aimed to investigate the vitamin D metabolic pathway genes polymorphisms and vitamin D levels with NH susceptibility. METHODS We retrospectively analyzed the clinical data, vitamin D levels and its metabolic pathway gene polymorphisms of 187 NH neonates and 149 controls at Tianjin Children's Hospital/Tianjin University Children's Hospital between April 2019 and August 2022. Vitamin D levels were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, and the genetic polymorphism of NADSYN1/DHCR7, GC, CYP2R1, CYP24A1 and CYP27B1 was detected by high resolution melting (HRM) analysis. RESULTS The frequency of vitamin D deficiency (25(OH)D < 15 ng/mL) was significantly increased in the NH group compared to controls. TT genotype of rs12785878 and GT genotype of rs10877012 were protective factors of vitamin D deficiency and NH, and GT genotype and dominant model carriers of rs12785878 had a higher risk of severe NH than the GG genotype carriers (GT genotype: OR: 2.43; 95% CI: 1.22-4.86; P = 0.012, dominant model: OR: 1.97; 95% CI: 1.04-3.73; P = 0.037). GC gene haplotype was associated with vitamin D deficiency. No significant SNP-SNP and SNP-vitamin D levels interaction combinations were found. CONCLUSIONS There were associations among NH, vitamin D deficiency and NADSYN1/DHCR7 and CYP27B1 polymorphisms, TT genotype of rs12785878 and GT genotype of rs10877012 could reduce the risk of vitamin D deficiency and NH. Furthermore, rs12785878 was significantly associated with severe NH.

Global Prevalence of Severe Neonatal Jaundice among Hospital Admissions: A Systematic Review and Meta-Analysis. J Clin Med 2023; 12:3738. [PMID: 37297932 PMCID: PMC10253859 DOI: 10.3390/jcm12113738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 05/03/2023] [Accepted: 05/05/2023] [Indexed: 06/12/2023] Open
Abstract
Evidence regarding the adverse burden of severe neonatal jaundice (SNJ) in hospitalized neonates in resource-constrained settings is sparse. We attempted to determine the prevalence of SNJ, described using clinical outcome markers, in all World Health Organization (WHO) regions in the world. Data were sourced from Ovid Medline, Ovid Embase, Cochrane Library, African Journals Online, and Global Index Medicus. Hospital-based studies, including the total number of neonatal admissions with at least one clinical outcome marker of SNJ, defined as acute bilirubin encephalopathy (ABE), exchange blood transfusions (EBT), jaundice-related death, or abnormal brainstem audio-evoked response (aBAER), were independently reviewed for inclusion in this meta-analysis. Of 84 articles, 64 (76.19%) were from low- and lower-middle-income countries (LMICs), and 14.26% of the represented neonates with jaundice in these studies had SNJ. The prevelance of SNJ among all admitted neonates varied across WHO regions, ranging from 0.73 to 3.34%. Among all neonatal admissions, SNJ clinical outcome markers for EBT ranged from 0.74 to 3.81%, with the highest percentage observed in the African and South-East Asian regions; ABE ranged from 0.16 to 2.75%, with the highest percentages observed in the African and Eastern Mediterranean regions; and jaundice-related deaths ranged from 0 to 1.49%, with the highest percentage observed in the African and Eastern Mediterranean regions. Among the cohort of neonates with jaundice, the prevalence of SNJ ranged from 8.31 to 31.49%, with the highest percentage observed in the African region; EBT ranged from 9.76 to 28.97%, with the highest percentages reported for the African region; ABE was highest in the Eastern Mediterranean (22.73%) and African regions (14.51%). Jaundice-related deaths were 13.02%, 7.52%, 2.01% and 0.07%, respectively, in the Eastern Mediterranean, African, South-East Asian and European regions, with none reported in the Americas. aBAER numbers were too small, and the Western Pacific region was represented by only one study, limiting the ability to make regional comparisons. The global burden of SNJ in hospitalized neonates remains high, causing substantial, preventable morbidity and mortality especially in LMICs.

Abstract
Phototherapy for jaundice in preterm infants should always be administered in accordance with specific guidelines. However, guidelines on phototherapy in very preterm and moderately preterm infants are currently lacking in France. We performed a nationwide quality improvement study of the management of jaundice in these preterm infants and compared the results with the international guidelines. Of the 275 maternity units initially contacted, 165 (60.0%) replied. Our results showed that clinical practice differs markedly from one unit to another - notably with regard to the prescription, administration, and monitoring of phototherapy and the reference curves used. Even though there is limited evidence on the safety and efficacy of phototherapy in very or moderately preterm infants, a French expert committee should be encouraged to develop consensus guidelines and thus improve quality of care in this setting.

Abstract
BACKGROUND Jaundice is a very common condition in newborns, affecting up to 60% of term newborns and 80% of preterm newborns in the first week of life. Jaundice is caused by increased bilirubin in the blood from the breakdown of red blood cells. The gold standard for measuring bilirubin levels is obtaining a blood sample and processing it in a laboratory. However, noninvasive transcutaneous bilirubin (TcB) measurement devices are widely available and used in many settings to estimate total serum bilirubin (TSB) levels. OBJECTIVES To determine the diagnostic accuracy of transcutaneous bilirubin measurement for detecting hyperbilirubinaemia in newborns. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL and trial registries up to 18 August 2022. We also checked the reference lists of all included studies and relevant systematic reviews for other potentially eligible studies. SELECTION CRITERIA We included cross-sectional and prospective cohort studies that evaluated the accuracy of any TcB device compared to TSB measurement in term or preterm newborn infants (0 to 28 days postnatal age). All included studies provided sufficient data and information to create a 2 × 2 table for the calculation of measures of diagnostic accuracy, including sensitivities and specificities. We excluded studies that only reported correlation coefficients. DATA COLLECTION AND ANALYSIS Two review authors independently applied the eligibility criteria to all citations from the search and extracted data from the included studies using a standard data extraction form. We summarised the available results narratively and, where possible, we combined study data in a meta-analysis. MAIN RESULTS We included 23 studies, involving 5058 participants. All studies had low risk of bias as measured by the QUADAS 2 tool. The studies were conducted in different countries and settings, included newborns of different gestational and postnatal ages, compared various TcB devices (including the JM 101, JM 102, JM 103, BiliChek, Bilitest and JH20-1C) and used different cutoff values for a positive result. In most studies, the TcB measurement was taken from the forehead, sternum, or both. The sensitivity of various TcB cutoff values to detect significant hyperbilirubinaemia ranged from 74% to 100%, and specificity ranged from 18% to 89%. AUTHORS' CONCLUSIONS The high sensitivity of TcB to detect hyperbilirubinaemia suggests that TcB devices are reliable screening tests for ruling out hyperbilirubinaemia in newborn infants. Positive test results would require confirmation through serum bilirubin measurement.

Abstract
BACKGROUND ABO incompatibility is a major risk factor for neonatal indirect hyperbilirubinemia (NIH), requiring treatment. It has been shown that there are racial differences in direct antiglobulin test (DAT) positivity and phototherapy need in the O--B versus (vs) O--A incompatibility. The comparison between the O--B and O--A incompatibility is not well studied in Saudi Arabia. AIMS We aimed to compare DAT positivity and phototherapy need in O-B vs O-A incompatibility in Saudi Arabia. METHODS This retrospective cohort study was conducted in one Saudi hospital. We included a convenience sample of neonates born between 01 January 2013 and 31 December 2021. We included healthy neonates admitted to the nursery care unit only, born at≥38 weeks gestation, and had normal G6PD levels. Neonates that had no G6PD level measurement or lost follow-up post-discharge were excluded. The data span was the first 14 days of life. RESULTS A total of 611 neonates met our inclusion criteria. Positive DAT was more prevalent in the O-B than the O-A incompatibility [43.5% vs 29.2%, p < 0.001). A greater odd of phototherapy need was observed in the O--B vs O-A incompatibility across various strata. Readmission for NIH, use of 360° exposure phototherapy, or intravenous immunoglobulin administration was more prevalent in the O-B than the O-A incompatibility (13.2% vs 5.0%, p < 0.001). A logistic regression analysis revealed that the O-B incompatibility modified the association between DAT positivity and phototherapy need. CONCLUSIONS The O-B incompatibility had a mediator effect on the relationship between DAT positivity and the need for phototherapy in the study population, which emphasizes that the O-B and O-A are not the same from the NIH point of view.

Abstract
BACKGROUND Neonatal hyperbilirubinemia is one of the common diseases of newborns that typically presents with yellow staining of skin, resulting in sequelaes such as hearing loss, motor and intellectual development disorders, and even death. The pathogenic factors of neonatal hyperbilirubinemia are complex. Different cases of hyperbilirubinemia may have a single or mixed etiology.
AIM To explore the etiological characteristics of severe hyperbilirubinemia in term newborns of eastern Guangdong of China.
METHODS Term newborns with severe hyperbilirubinemia in one hospital from January 2012 to December 2021 were retrospectively analyzed. The etiology was determined according to the laboratory results and clinical manifestations.
RESULTS Among 1602 term newborns with hyperbilirubinemia in eastern Guangdong of China, 32.20% (580/1602) was severe hyperbilirubinemia. Among the causes of severe hyperbilirubinemia, neonatal hemolysis accounted for 15.17%, breast milk jaundice accounted for 12.09%, infection accounted for 10.17%, glucose-6-phosphate dehydrogenase (G6PD) deficiency accounted for 9.14%, and the coexistence of multiple etiologies accounted for 6.55%, unknown etiology accounted for 41.72%. ABO hemolysis and G6PD deficiency were the most common causes in the 20 cases with bilirubin encephalopathy. 94 severe hyperbilirubinemia newborns were tested for uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1)*6 variant (rs4148323, c.211G>A, p.Arg71Gly), 9 cases were 211 G to A homozygous variant, 37 cases were 211 G to A heterozygous variant, and 48 cases were wild genotypes.
CONCLUSION The main cause for severe hyperbilirubinemia and bilirubin encephalopathy in eastern Guangdong of China were the hemolytic disease of the newborns, G6PD deficiency and infection. UGT1A1 gene variant was also a high-risk factor for neonatal hyperbilirubinemia. Targeted prevention and treatment according to the etiology may reduce the occurrence of bilirubin encephalopathy and kernicterus.

Abstract
BACKGROUND The aim of this study is to determine the value of the questions asked in routine follow-up, the cord blood bilirubin (CBB) and bilirubin/albumin (B/A) ratio in estimating the risk of developing hyperbilirubinemia. METHODS Term and healthy 217 newborns whose CBB and albumin could be obtained and whose needed to be measured bilirubin level at the 24thand 72nd hours of life were included. Nutrition, sex and nationality, consanguinity between parents, jaundice in the sibling (s), mother's medications were questioned. CBB and albumin, serum total bilirubin (STB), serum albumin and transcutaneous bilirubin (TcB) at the 24th and 72nd hours of life, were recorded. RESULTS CBB and cord B/A ratio, STB and serum B/A ratio, and TcB at the 24th and 72nd hours were found to be higher in the babies who received the phototherapy (p < 0.001 for all). The moderate positive correlation (correlation coefficient 0.383) at the 24th hour and strong positive correlation (correlation coefficient 0.759) at the 72nd hour between STB and TcB measurements was detected. In estimating the need for phototherapy the sensitivity and specificity of CBB were 74.2% and 56.5%, the sensitivity and specifity of cord B/A was 74.2%, and 61.8%. The cut-off value of CBB in estimating the need for phototherapy is 1.8, and the cut-off value of the cord B/A ratio is 0.56. When the cut-off value is 1.8 for the CCB and the cord B/A ratio is 0.56, the positive predictive values are low, but the negative predictive values are significantly high (92.9% and 93.5%, respectively) in determining the need for phototherapy. DISCUSSION CBB and B/A ratio are important in predicting the possibility of indirect hyperbilirubinemia (IHB) development. Babies should be followed closely in terms of IHB development when their CBB value is 1.8 mg/dL and above, and the cord blood B/A ratio is 0.56 and above.

Abstract
INTRODUCTION Hyperbilirubinaemia is one of the most important causes of re-admission in the early neonatal period. The socioeconomic factors are one of the most common reasons for early discharge in a developing country like India. OBJECTIVES This study aims to evaluate and analyze the statistical correlation of umbilical cord blood bilirubin, albumin, nucleated red blood cells (nRBC), and reticulocyte count as early predictors of neonatal hyperbilirubinemia. METHOD A prospective observational study was conducted from November 2015 to April 2017 in a tertiary care hospital in North Karnataka, India. Umbilical cord blood was collected at birth for analysis of bilirubin, albumin, reticulocyte count, and nRBC in term neonates. Total serum bilirubin (TSB) levels were estimated using the VITROS BuBc Slide method at 72 hours of life. Data were analyzed using SPSS version 23 (IBM Corp., Armonk, NY). RESULTS A total of 200 term neonates were enrolled in the study, out of which 123 completed follow-ups. Of the 66 newborns who had cord bilirubin levels ≥1.75 mg/dl, 23 (34.8%) developed hyperbilirubinemia after 72 hours of life, whereas 10 of the 57 newborns (17.5%) whose cord bilirubin levels <1.75 mg/dl developed hyperbilirubinemia after 72 hours of life. Cord blood albumin of ≥3.75 g/dl was seen in 93 neonates, of which 18 (19.4%) developed hyperbilirubinemia after 72 hours of life and 15 (50%) with <3.75 g/dl developed hyperbilirubinemia after 72 hours of life. Cord reticulocyte count ≥4.95% was seen in 54 neonates; 20 (37.03%) developed hyperbilirubinemia, whereas in 69 neonates with <4.95%, 13 (18.84%) developed hyperbilirubinemia after 72 hours of life. Of the 62 neonates who had cord nRBC ≥3.5%, 28 (45.2%) neonates developed hyperbilirubinemia after 72 hours of life, whereas 5 of the 61 neonates (8.19%) with cord nRBC <3.5% developed hyperbilirubinemia after 72 hours of life. CONCLUSIONS Cord blood bilirubin, albumin, reticulocyte counts, and nucleated RBC can be used as predictors of subsequent neonatal hyperbilirubinemia.

Abstract
BACKGROUND Phototherapy is a widely accepted, effective first-line therapy for neonatal jaundice. It is traditionally used continuously but intermittent phototherapy has been proposed as an equally effective alternative with practical advantages of improved maternal feeding and bonding. The effectiveness of intermittent phototherapy compared with continuous phototherapy is unknown. OBJECTIVES To assess the safety and effectiveness of intermittent phototherapy compared with continuous phototherapy. SEARCH METHODS Searches were conducted on 31 January 2022 in the following databases: CENTRAL via CRS Web, MEDLINE and Embase via Ovid. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-randomised trials. SELECTION CRITERIA We included RCTs, cluster-RCTs and quasi-RCTs comparing intermittent phototherapy with continuous phototherapy in jaundiced infants (both term and preterm) up to the age of 30 days. We compared intermittent phototherapy with continuous phototherapy by any method and at any dose and duration as defined by the authors. DATA COLLECTION AND ANALYSIS Three review authors independently selected trials, assessed trial quality and extracted data from included studies. We performed fixed-effect analyses and expressed treatment effects as mean difference (MD), risk ratio (RR) and risk difference (RD) with 95% confidence intervals (CIs). Our primary outcomes of interest were rate of decline of serum bilirubin, and kernicterus. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included 12 RCTs (1600 infants) in the review. There is one ongoing study and four awaiting classification. There was little or no difference between intermittent phototherapy and continuous phototherapy with respect to rate of decline of bilirubin in jaundiced newborn infants (MD -0.09 micromol/L/hr, 95% CI -0.21 to 0.03; I² = 61%; 10 studies; 1225 infants; low-certainty evidence). One study involving 60 infants reported no incidence of bilirubin induced brain dysfunction (BIND). It is uncertain whether either intermittent or continuous phototherapy reduces BIND because the certainty of this evidence is very low. There was little or no difference in treatment failure (RD 0.03, 95% CI 0.08 to 0.15; RR 1.63, 95% CI 0.29 to 9.17; 1 study; 75 infants; very low-certainty evidence) or infant mortality (RD -0.01, 95% CI -0.03 to 0.01; RR 0.69, 95% CI 0.37 to 1.31 I² = 0%; 10 studies, 1470 infants; low-certainty evidence). AUTHORS' CONCLUSIONS: The available evidence detected little or no difference between intermittent and continuous phototherapy with respect to rate of decline of bilirubin. Continuous phototherapy appears to be more effective in preterm infants, however, the risks of continuous phototherapy and the potential benefits of a slightly lower bilirubin level are unknown. Intermittent phototherapy is associated with a decrease in the total number of hours of phototherapy exposure. There are theoretical benefits to intermittent regimens but there are important safety outcomes that were inadequately addressed. Large, well designed, prospective trials are needed in both preterm and term infants before it can be concluded that intermittent and continuous phototherapy regimens are equally effective.

Abstract
The primary objective of this research was to evaluate the use of intravenous immunoglobulin (IVIG) in infants with hemolytic disease, to assess compliance with the American Academy of Pediatrics (AAP) guideline recommendations, and to review the data on which the guidelines were based. This retrospective study evaluated all infants in the NICU (neonatal intensive care unit) who received IVIG between January 2018 and December 2020 (n = 71). Total serum bilirubin (TSB) levels surrounding the time of IVIG administration, rate of rise of bilirubin, and direct antiglobulin test (DAT) status were evaluated to determine the appropriateness of IVIG use based on the 2004 AAP recommendations that was current at the time of the study. Fifty-nine infants received IVIG for hyperbilirubinemia. Of them, 80% had an ABO mismatch, 19% had Rh mismatch, and 71% were DAT-positive. Phototherapy was started at an average of 7 h of age, and the first IVIG dose was administered at an average of 13 h of life; nearly 25% received a second IVIG dose. One infant (1.6%) met all three AAP guideline criteria of being DAT-positive, bilirubin within 3 of exchange level, and rising bilirubin despite intensive phototherapy. Twenty-five (42%) babies were DAT positive and met one of the other two criteria. Only 12% (n = 7) had a bilirubin within 3 of exchange level. Most infants who received IVIG for hyperbilirubinemia did not meet the AAP criteria, prompting us to develop an institution-specific IVIG clinical practice guideline. The 2022 AAP guideline was published after our study was completed, but it confirmed our belief that IVIG usage should be more restricted and the criteria more explicit.

Abstract
The aim of our study was to evaluate oxidative stress and thiol-disulfide homeostasis in term newborns receiving phototherapy. The study was planned as a single-blind, intervention study in a single center with level 3 neonatal intensive care unit to investigate the effect of phototherapy on the oxidative system in term newborns with hyperbilirubinemia. Neonates with hyperbilirubinemia were treated with total body exposure phototherapy technique for 18 h using a Novos® device. Blood samples of 28 term newborns were taken before and after phototherapy. Total and native thiol, total antioxidant status (TAS) and total oxidant status (TOS), and oxidative stress index (OSI) levels were measured. The 28 newborn patients included 15 (54%) males and 13 (46%) females with a mean birthweight of 3080.1 ± 366.5 g. Native and total thiol levels were found to be decreased in patients receiving phototherapy (p = 0.021, p = 0.010). Besides, significantly lower TAS and TOS levels were found after phototherapy (p < 0.001, p < 0.001). We found that decreased thiol levels were related to increased oxidative stress. We also determined significantly the lower bilirubin levels after phototherapy (p < 0.001). In conclusion, we found that phototherapy treatment induced decreased oxidative stress associated with hyperbilirubinemia in neonates. Thiol-disulfide homeostasis can be used as a marker of oxidative stress due to hyperbilirubinemia in the early period.

Amin SB. Bilirubin-Displacing Effect of Ceftriaxone in Infants With Unconjugated Hyperbilirubinemia Born at Term. J Pediatr 2023; 254:91-95. [PMID: 36336007 DOI: 10.1016/j.jpeds.2022.10.030] [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: 09/09/2022] [Revised: 10/12/2022] [Accepted: 10/30/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To evaluate the effect of intravenous (IV) ceftriaxone on free bilirubin concentrations in infants with unconjugated hyperbilirubinemia born at term. STUDY DESIGN A prospective study was performed with subjects serving as their own controls. Our inclusion criteria were infants born at term <7 days old with sepsis and receiving IV antibiotics for >3 days and resolving hyperbilirubinemia with total serum bilirubin levels between 6 and12 mg/dL by day 4 of life. Free bilirubin concentrations were measured by the peroxidase method using a UB analyzer and a Zone Fluidics device before (baseline) and 15 minutes after (follow-up) IV ceftriaxone administration on postnatal days 4 to 6. Paired measurements of free bilirubin were analyzed using a Student paired t-test or Wilcoxon signed-rank test. RESULTS In total, 27 infants were studied. The mean free bilirubin (μg/dL) at follow-up was not different from that at baseline when measured by the UB analyzer (P = .78). The mean free bilirubin was significantly lower at follow-up compared with baseline when measured by the Zone Fluidics device (P = .02). The ratio of a free bilirubin with and without ceftriaxone, an index of displacing effect, was 1.02 (95% CI 0.89-1.14) using the UB analyzer and 0.58 (95% CI 0.30-0.86) using the Zone Fluidics device. CONCLUSIONS Ceftriaxone is not associated with a bilirubin-displacing effect in infants with a mild unconjugated hyperbilirubinemia. Home therapy with once-daily intramuscular ceftriaxone may be an alternative option for management of sepsis in asymptomatic infants with a mild unconjugated hyperbilirubinemia born at term.

THE JOURNAL OF PAIN 2023; 24:387-402. [PMID: 36243317 DOI: 10.1016/j.jpain.2022.09.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 09/15/2022] [Accepted: 09/19/2022] [Indexed: 11/05/2022]
Abstract
Needle procedures are among the most common causes of pain and distress for individuals seeking health care. While needle pain is especially problematic for children needle pain and associated fear also has significant impact on adults and can lead to avoidance of appropriate medical care. Currently there is not a standard definition of needle pain. A taxonomy, or classification system, for acute needle pain would aid research efforts and enhance clinical care. To meet this need, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks public-private partnership with the U.S. Food and Drug Administration, the American Pain Society, and the American Academy of Pain Medicine formed the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks-American Pain Society-American Academy of Pain Medicine Pain Taxonomy initiative. One of the goals of this initiative was to develop taxonomies for acute pain disorders, including needle pain. To accomplish this, a working group of experts in needle pain was convened. Based on available literature and expert opinion, the working group used a 5-dimenional structure (diagnostic criteria, common features, modulating factors, impact and/or functional consequences, and putative mechanisms) to develop an acute pain taxonomy that is specific needle pain. As part of this, a set of 4 diagnostic criteria, with 2 modifiers to account for the influence of needle associated fear, are proposed to define the types of acute needle pain. PERSPECTIVE: This article presents a taxonomy for acute needle pain. This taxonomy could help to standardize definitions of acute pain in clinical studies of patients undergoing needle procedures.

Neonatal hyperbilirubinemia: Assessing variation in knowledge and practice. PLoS One 2023; 18:e0282413.

Abstract
INTRODUCTION Neonatal hyperbilirubinemia (NH) is commonly diagnosed and managed by pediatricians in various clinical settings. The 2004 American Academy of Pediatrics (AAP) Clinical Practice Guideline on NH is widely cited, but literature examining variation across pediatric specialties is limited. This study aimed to assess baseline knowledge and practice habits regarding NH among pediatric providers across various specialties immediately prior to the release of the 2022 NH clinical practice guideline. METHODS A non-probability, convenience, self-selected sampling survey was electronically distributed to 311 subjects across five specialties within one pediatric healthcare institution. The survey included eight multiple choice knowledge-based questions with confidence assessments and five management-based questions assessing respondent agreement on a 5-point scale. To compare groups, the Kruskal-Wallis and Mann-Whitney tests were used for continuous variables, and the chi-square and Fisher's exact tests were used for categorical variables. RESULTS The overall survey response rate is 46%. There were significant differences between specialties' knowledge regarding NH (p<0.05). There were also significant differences between specialties' confidence ratings, independent of choosing the correct response (p<0.05). For select management-based questions, there were also significant differences between specialties (p<0.05). A majority of respondents (56%) indicated phototherapy treatment thresholds should remain the same in updated management guidelines. CONCLUSIONS Significant variations in knowledge and management of NH were identified among pediatric specialties. This suggests dissemination of new guidelines must be cognizant of different constraints impacting knowledge and practice across specialties.

Abstract
BACKGROUND Exposing blood serum samples to ambient white light-emitting diode (WLED) light may accelerate bilirubin photoisomer production. We previously demonstrated the quantitative effect of bilirubin configurational isomers (BCI) on direct bilirubin (DB) value using the vanadate oxidation method. However, the effects of bilirubin structural photoisomers (BSI) remain unclear. METHODS In Study 1, the relationship between WLED irradiation time and BSI production was examined. Serum samples from five neonates were irradiated with WLED light for 0, 10, 30, 60 and 180 min. Bilirubin isomer concentration and BSI production rates were calculated. In Study 2, we performed quantitative investigation of BSI effect on DB values: Differences in DB, BCI and BSI values before and after irradiation were calculated as ⊿DB, ⊿BCI and ⊿BSI, respectively. Assuming the coefficient of BCI affecting DB values was 'a', relational expression was ⊿DB = a*⊿BSI + 0.19*⊿BCI. Serum samples from 15 neonates were irradiated with green LED light for 10 and 30 s. The respective bilirubin isomer levels were measured, and the coefficient was derived. RESULTS In Study 1, the median BSI production rate was 0.022 mg/dL per min in specimens with an unconjugated bilirubin concentration of 10.88 mg/dL. In Study 2, assuming that ⊿DB-0.19*⊿BCI was Y and ⊿BSI was X, the relational expression was Y = 0.34X-0.03 (R2 = 0.87; p < .01) and a = 0.34. CONCLUSIONS Under ambient WLED light, serum sample generated 1.3 mg/dL BSIs in 1 h. Approximately 34% (0.44 mg/dL) of BSI concentrations was measured as DB when using the vanadate oxidation method according to the above equation.

Abstract
The study was aimed to evaluate the performance of a newly developed spectroscopy-based non-invasive and noncontact device (SAMIRA) for the simultaneous measurement of hemoglobin, bilirubin and oxygen saturation as an alternative to the invasive biochemical method of blood sampling. The accuracy of the device was assessed in 4318 neonates having incidences of either anemia, jaundice, or hypoxia. Transcutaneous bilirubin, hemoglobin and blood saturation values were obtained by the newly developed instrument which was corroborated with the biochemical blood tests by expert clinicians. The instrument is trained using Artificial Neural Network Analysis to increase the acceptability of the data. The artificial intelligence incorporated within the instrument determines the disease condition of the neonate. The Pearson's correlation coefficient, r was found to be 0.987 for hemoglobin estimation and 0.988 for bilirubin and blood gas saturation respectively. The bias and the limits of agreement for the measurement of all the three parameters were within the clinically acceptance limit.

Abstract
OBJECTIVE The objective of the paper was to investigate how neonatal hematologic outcomes vary by major placental histopathology categories. STUDY DESIGN Placental pathology reports from 5263 subjects were coded into individual placental lesions. Infant hematologic data (complete blood count parameters (n = 1945), transfusions, and phototherapy) were compared by placental pathologic phenotype. RESULTS Red blood cell transfusions were more likely with maternal vascular malperfusion (MVM; OR 9.4 [2.2, 40.8]) and chronic inflammation (1.7 [1.04, 2.7]). White blood cells were decreased with MVM (10.6 103/μL vs 16.4) and elevated with acute inflammation (AI; 18.6 vs 11.9). Thrombocytopenia was associated with MVM (OR 3.7 [2.2, 5.1]) and fetal vascular malperfusion (FVM; OR 2.6 [1.5, 4.6]). Platelet transfusions were more likely with MVM (OR 8.3 [4.6, 15.0]) and FVM (OR 2.9 [1.4, 6.1]). Phototherapy was associated with MVM (OR 3.3 [2.7, 4.0]) and AI (OR 0.8 [0.6, 0.9]). CONCLUSIONS Neonatal hematologic outcomes are associated with the in utero environment described by placental pathology.

Abstract
AIM Neonatal jaundice is an important and prevalent condition that can cause kernicterus and mortality. This study validated a smartphone-based screening application (Biliscan) in detecting neonatal jaundice. METHODS A cross-sectional prospective study was conducted at the neonatal unit in a tertiary teaching hospital between August 2020 and October 2021. All babies born at the gestation of 35 weeks and above with clinical jaundice or are recommended for screening of jaundice within 21 days of post-natal age were recruited. Using Biliscan, images of the babies' skin over the sternum were taken against a standard colour card. The application uses feature extraction and machine learning regression to estimate the bilirubin level. Independent Biliscan bilirubin estimates (BsB) were made and compared with total serum bilirubin (TSB) and transcutaneous bilirubin (TcB) levels. Bland Altman plots were used to establish the agreement between BsB and TSB, as well as TcB, using the clinically acceptable limits of agreement of ±35 μmol/L, which were defined a priori. Pearson correlation coefficient was assessed to establish the strength of the relationship between BsB versus TSB and TcB. Diagnostic accuracy was assessed through receiver operating characteristic curve analysis. RESULTS Sixty-one paired TSB-BsB and 85 paired TcB-BsB measurements were obtained. Bland Altman plot for the entire group showed that 54% (33/61) of the pairs of TSB and BsB readings and 66% (56/85) of the pairs of TcB and BsB readings were within the maximum clinically acceptable difference of 35 μmol/L. Pearson r for BsB versus TSB and TcB was 0.54 (P < 0.001) and 0.66 (P < 0.001) respectively. Compared with TSB, the recommended gold standard measure for jaundice, Biliscan has a sensitivity of 76.92% and specificity of 70.83% for jaundice requiring phototherapy. The positive and negative predictive values in term infants were 93.3% and 36.9%, respectively. CONCLUSION Our results suggest that there is moderate correlation and mediocre agreement between BsB and TSB, as well as TcB. Improvement to the application algorithm and further studies that include a larger population, and a wider range of bilirubin values are necessary before the tool may be considered for use in screening of jaundice in newborns.

Abstract
The last several years have seen accelerated activity and discourse directed at antiracism. Specifically following the 2020 murder of George Floyd, institutions across the country engaged in a range of introspective exercises and transparent reckonings examining their practices, policies, and history insofar as equity and racism is concerned. The authors of this article, both active protagonists in this domain, have been, and continue to be, part of ongoing national efforts and have learned much about the strategies and tactics necessary to initiate, engage, and sustain traction on the path to antiracism.

Abstract
OBJECTIVES Phototherapy is demonstrated to cause hypocalcemia by decreasing melatonin levels and increasing cortisol levels. However, the relationship between parathyroid hormone (PTH) level and calcium has not been previously evaluated in patients receiving phototherapy. Our study aimed to evaluate the effect of phototherapy on ionized calcium (iCa), total calcium (tCa), corrected calcium (cCa), magnesium (Mg), phosphorus (P), 25-hydroxyvitamin D (25(OH)D), and PTH levels. METHODS Infants who were born at term and received inpatient phototherapy for indirect hyperbilirubinemia were included in our study. The patients' gestational age, birth weight, and phototherapy durations were recorded. Total bilirubin, albumin, iCa, tCa, cCa, Mg, 25(OH)D, and PTH levels before and after phototherapy were compared. Laboratory results were also compared between patients who received phototherapy for ≤24 h, 25-47 h, and ≥48 h. RESULTS A total of 166 term infants were included in the study. The mean duration of phototherapy was 31.9 ± 9.2 h. Albumin levels before and after phototherapy were similar (p=0.246). However, there were significant decreases in iCa, tCa, cCa, Mg, 25(OH)D, and PTH levels after phototherapy (p<0.001), while P level was significantly increased after phototherapy (p<0.001). In addition, P levels increased with >24 h of phototherapy, while iCa, tCa, cCa, Mg, 25(OH)D, and PTH levels decreased significantly with ≥48 h of phototherapy (p=0.002, p=0.008, p=0.001, p=0.012, and p<0.001, respectively). CONCLUSIONS This study demonstrates that PTH suppression is one of the causes of phototherapy-induced hypocalcemia.

Abstract
Phototherapy is an efficient and safe way to reduce high levels of free 4Z,15Z-bilirubin (ZZ-BR) in the serum of newborns. The success of BR phototherapy lies in photoinduced configurational and structural isomerization processes that form excretable isomers. However, the physical picture of photoinduced photoisomerization of ZZ-BR is still unclear. Here, we strategically implement tunable femtosecond stimulated Raman spectroscopy and several time-resolved electronic spectroscopies, assisted by quantum chemical calculations, to dissect the detailed primary configurational isomerization dynamics of free ZZ-BR in organic solvents. The results of this study demonstrate that upon photoexcitation, ultrafast configurational isomerization proceeds by a volume-conserving "hula twist", followed by intramolecular hydrogen-bond distortion and large-scale rotation of the two dipyrrinone halves of the ZZ-BR isomer in a few picoseconds. After that, most of the population recovers back to ZZ-BR, and a very small amount is converted into stable BR isomers via structural isomerization.

Abstract
BackgroundThe kangaroo-mother care method (KMC) is a skin-to-skin contact-centered care approach with numerous benefits for neonates, but its impact on the treatment of jaundiced neonates is unknown. This study aimed to investigate the efficacy of KMC combined with neonatal phototherapy (NNPT) in treating neonates with non-pathological jaundice.MethodsRelevant articles were searched in PubMed, Embase, Web of Science, and Cochrane Library databases from database establishment to April 2022. The outcomes included, without limitation, serum bilirubin levels, and duration of phototherapy.ResultsThis meta-analysis included five studies (4 randomized controlled trials and 1 observational study) involving four hundred eighty-two neonates with non-pathological jaundice. The results showed that the group receiving KMC combined with NNPT had lower serum bilirubin at 72 h after intervention [weighted mean difference (WMD) = −1.51, p = 0.03], shorter duration of phototherapy [standard mean difference (SMD) = −1.45, p < 0.001] and shorter duration of hospitalization (SMD = −1.32, p = 0.002) compared to NNPT group. There was no difference in peak bilirubin in both groups of neonates (WMD = −0.12, p = 0.62).ConclusionsKMC combined with NNPT helped to treat non-pathological jaundice in newborns compared to NNPT alone.

Abstract
The American Academy of Pediatrics updated the guidelines for the management of hyperbilirubinemia in the newborn infants with a gestational age of ≥35 weeks in September 2022. Based on the evidence over the past 18 years, the guidelines are updated from the aspects of the prevention, risk assessment, intervention, and follow-up of hyperbilirubinemia in the newborn infants with a gestational age of ≥35 weeks. This article gives an interpretation of the key points in the guidelines, so as to safely reduce the risk of bilirubin encephalopathy and unnecessary intervention.

Abstract
OBJECTIVE To describe bilirubin levels in neonates ≥350/7 gestational weeks, receiving delayed cord clamping (CC), in relation to the updated Bhutani nomogram. STUDY DESIGN This was a retrospective, observational study based on data from medical records and local data sheets. Singleton neonates, born vaginally at a gestational age ≥350/7, and with a registered time to CC and at least one registered bilirubin, were included. We excluded neonates with positive direct antiglobulin test or hemolytic disorders. Adjusted analyses were performed using ANOVA and linear or logistic regression. RESULTS We analyzed 558 neonates, mean gestational age (SD) 39.9 (1.3) weeks. CC was performed at a median (IQR) time of 6 (5-8) minutes. The dataset contained 1330 bilirubin measurements. Median (IQR) age at bilirubin measurement was 37 (22-54) hours. Bilirubin percentiles in neonates with CC time ≥2 minutes were similar, or lower, compared with the Bhutani nomogram between 12 and 72 hours, but with greater 95th percentile at later hours of age. Phototherapy was initiated in 13 (2.3 %) of the neonates. We found no association between time to CC and hyperbilirubinemia (β = -0.05, P = .07). Need for phototherapy was marginally greater in neonates with shorter time to CC. CONCLUSIONS Bilirubin levels were not correlated to time to CC. Our findings indicate that CC beyond 2 minutes can be performed without additional monitoring for jaundice.

Abstract
BACKGROUND Among neonates with hemolytic disease of the fetus and newborn (HDFN), we aimed to describe the frequency of central-line use, indications for insertion, and incidence of confirmed and suspected sepsis, including antibiotic treatment over a 10-year surveillance period. STUDY DESIGN AND METHODS All neonates with HDFN admitted to our neonatal intensive care unit between January 2012 and December 2021 were included in this retrospective, cohort study. Annual proportions of infants with a central-line and central-line-associated bloodstream infection (CLABSI) rates (per 1000 central-line days and per 100 infants) were evaluated. Numbers of confirmed and suspected early- and late-onset sepsis episodes were assessed over the entire study period. RESULTS Of the 260 included infants, 25 (9.6%) were evaluated for suspected sepsis, with 16 (6.2%) having ≥1 confirmed sepsis episode. A total of 123 central-lines were placed in 98 (37.7%) neonates, with impending exchange transfusion (ET) being the most frequent indication. Of the 34 (34.7%) neonates in whom a central-line was placed due to impending ET, 11 (32.4%) received no ET. Overall CLABSI incidence was 13.58 per 1000 central-line days. Neonates with a central-line had a higher risk for confirmed late-onset infection (RR 1.11, 95% CI: 1.04-1.20) and sepsis work-up (RR 1.10, 95% CI: 1.03-1.17) compared to infants without a central-line. CONCLUSIONS Sepsis incidence among neonates with HDFN remains high, in particular in those with a central-line. Considering the substantial proportion of neonates with a central-line without eventual ET, central-line placement should be delayed until the likelihood of ET is high.

Abstract
Neonatal jaundice is a common medical condition that affects neonates in the early days of life. Nurses and midwives play important role in the identification and management of neonatal jaundice and the promotion of good neonatal health and education. Their clinical knowledge of neonatal jaundice may influence their attitude and practices toward the identification and management of neonatal jaundice. The study results showed that the level of good knowledge, attitudes, and practices toward neonatal jaundice management was 69.30% (140/202), 64.90% (131/202), and 62.90% (127/202), respectively. The inferential statistics showed a positive association between good knowledge and attitudes toward neonatal jaundice and good practices of neonatal jaundice management. Suggestively, nurses and midwives who have and demonstrate better clinical knowledge and exhibit positive attitudes are more likely to implement appropriate practices for the management of neonatal jaundice. Healthcare providers should therefore invest in life-long learning activities for staff, especially in the study setting.

Abstract
AIM To examine the effects of breastfeeding support given by video call on anxiety, breastfeeding self-efficacy, and newborn outcomes. METHODS We conducted a randomized controlled experimental trial with 72 women and their babies. Participants were randomly assigned to the intervention (video call) group (VCG: standard care + video call) and control group (CG: standard care). The primary outcomes of this study were the mean postpartum maternal anxiety level and the mean breastfeeding self-efficacy level. The secondary outcome was neonatal outcomes. This study followed the CONSORT (Consolidated Standards of Reporting Trials) checklist. RESULTS Women in VCG had lower anxiety levels than the CG at postpartum 2 weeks (mean difference [MD] 25.42, p = .000) and 1 month (MD 47.72, p = .000). The breastfeeding self-efficacy level of women in the VCG was higher than the CG at postpartum 2 weeks (MD 13.18, p = .007) and 1 month (MD 10.1, p = .001). The newborns in VCG had higher weight gain and daily breastfeeding frequency than the CG at the postpartum second week (MD 9.64, p = .001, MD 2.88, p = .000; respectively) and 1 month (MD 47.16, p = .000, MD 2.98, p = .000; respectively). There were lower rates of challenges of breastfeeding, hyperbilirubinemia, and feeding with formula in VCG than CG at the postpartum second week (p = .043, p = .043, p = .039; respectively). CONCLUSIONS Breastfeeding support via video calling has positive effects on maternal anxiety, breastfeeding self-efficacy, and newborn health. Postpartum caregivers may benefit from video calling for breastfeeding support.

Abstract
Objective To explore the effect of delayed cord clamping on preterm infants. Methods A retrospective analysis was conducted using the clinical data of 163 preterm infants with a gestational age of 34-36 weeks + 6 who were admitted to the neonatology department within 2 hours after birth. The blood routine examination indices within 2 hours and at 3-5 days after birth, the biochemical indices and arterial blood gas (ABG) indices within 2 hours after birth, and the hemoglobin level 5-6 months after birth were compared between the early cord clamping (ECC) group and the delayed cord clamping (DCC) group. Results Compared with the ECC group, the DCC group had significantly higher venous blood levels of red blood cells, hemoglobin, and hematocrit within 2 hours and at 3-5 days after birth. The ABG bicarbonate (HCO3) level within 2 hours after birth was obviously higher in the DCC group than in the ECC group, and the ABG absolute base excess(BE) and lactate levels were lower in the DCC group than in the ECC group (P < 0.05). There was no significant difference between the two groups in the incidence of hypothermia, hypoglycemia, respiratory distress, septicemia, feeding intolerance, polycythemia, and hyperbilirubinemia requiring phototherapy during hospitalization (P > 0.05). Compared with the ECC group, the DCC group had a significantly higher venous blood hemoglobin level 5-6 months after birth. The incidence of anemia in the DCC group was significantly lower than in the ECC group (P < 0.05). Conclusion Delayed cord clamping can significantly increase the hemoglobin levels of preterm infants at birth and at 5-6 months after birth and can improve the oxygen circulation supply to the organs of such infants. Therefore, delayed cord clamping can improve the prognosis of preterm infants.

Abstract
Background Nurses and midwives play important role in managing neonatal jaundice and provide nursing health education to mothers on preventive and remedial measures to neonatal jaundice. However, the Knowledge, Attitudes, and Practices of nurses and midwives towards neonatal jaundice is not well understood in the Northern Region of Ghana. Aim of the study The study assessed the knowledge, attitudes, and practices of nurses and midwives towards the management of neonatal jaundice. Design and Method This is a hospital-based descriptive cross-sectional study, conducted between the periods of January 2021 to August 2021 in the Tamale Teaching Hospital, Northern Region, Ghana. Descriptive analysis such as mean, standard deviation, frequencies, and percentages were performed to give general description of the variables. Simple Pearson Chi-square test and logistic regression models were performed to test the level of associations between the outcome and independent variables and predictors for neonatal jaundice. A p-value of <.05 was considered statistically significant for the test of association. Results Among the 202 nurses and midwives, the mean age was 30.6 ± 3.8 years and majority were females (71.3%). The overall good knowledge, attitudes, and practices score towards neonatal jaundice was 69.30%, 64.90%, and 62.90%, respectively. After adjusting for other variables, good knowledge (adjusted odds ratio [AOR] = 22.41(10.21-49.18) p < .001) and good attitude (AOR = 25(11.86-55.07) p < .001) were positively associated with practices towards neonatal jaundice. Conclusion/Interpretation The participants demonstrated substantial knowledge, attitudes, and practices towards neonatal jaundice. However, there still exist some gaps in their knowledge, attitudes, and practices towards neonatal jaundice that need to be addressed to improve neonatal health outcomes in the study setting.

Abstract
Objective This study aimed to evaluate the predictive performance of end-tidal carbon monoxide corrected to ambient carbon monoxide (ETCOc) values phototherapy in neonates with significant hyperbilirubinemia. Methods A prospective study was conducted on neonates with significant hyperbilirubinemia who received phototherapy between 3 and 7 days of life. The breath ETCOc and serum total bilirubin of the recruited infants were measured on admission. Results The mean ETCOc at admission in 103 neonates with significant hyperbilirubinemia was 1.70 ppm. The neonates were categorized into two groups: phototherapy duration ≤72 h (n = 87) and >72 h (n = 16) groups. Infants who received phototherapy for >72 h had significantly higher ETCOc (2.45 vs. 1.60, P = 0.001). The cutoff value of ETCOc on admission for predicting longer phototherapy duration was 2.4 ppm, with a sensitivity of 62.5% and specificity of 88.5%, yielding a 50% positive predictive value and a 92.7% negative predictive value. Conclusion ETCOc on admission can help predict the duration of phototherapy in neonates with hyperbilirubinemia, facilitate clinicians to judge disease severity, and make clinical communication easier and more efficient.

Abstract
BACKGROUND Transcutaneous bilirubin (TcB) measurement is useful, but dissociation with total serum bilirubin (TSB) is a clinical problem in measurement. We verified the accuracy of the latest version of the JM-105 jaundice meter. METHODS The TcB, TSB, and hematocrit (Hct) measurements obtained in the first 4 days of life in 2788 term neonates were analyzed. RESULTS When divided into 2-mg/dL classes, the difference between the TcB and TSB measurements did not change as TcB increased, but both overestimation and underestimation of TcB increased as TcB increased. At TcB greater than 11 mg/dL, inaccurate measurements with dissociation greater than 2 mg/dL exceeded 10% of the TcB measurements. The Hct value was associated with overestimation and underestimation. CONCLUSION To evaluate neonatal jaundice accurately, it is desirable to measure TSB by blood sampling before discharge from obstetrics or in the case of worsening jaundice on day 4 or 5 of life.

Abstract
BACKGROUND Intravenous immunoglobulin G (IVIG) is used to treat blood-type incompatibility hemolytic disease of newborns (BTHDN). Although IVIG's efficacy for treating BTHDN has been challenged, as an updated systematic review suggests, IVIG could significantly reduce exchange transfusions. We conducted a mail-in questionnaire survey to ascertain actual use of IVIG for BTHDN in Japan. METHODS The survey, conducted in 2014, included infants born between January 1, 2009, and December 31, 2013. Questionnaires were sent to the heads of neonatal intensive care units (NICUs) at perinatal centers of the Japan Neonatologist Association. RESULTS A total of 195 centers (64.6%) responded to the questionnaire. During the study period, 170 centers (87.2%) reported incidences of BTHDN. Among these centers, there were 1726 diagnosed cases of BTHDN in neonates. Of these cases, 419 infants were treated with IVIG in 127 centers, representing approximately 74.7% of all centers. After the exclusion of cases with missing data and those where consent for data usage was not obtained, a total 916 infants were included in this study. Of these, 219 (23.9%) were treated with IVIG after phototherapy, and 187 (20.4%) of these infants did not require further blood exchange transfusion. The IVIG dosages ranged from 40 to 1200 mg/kg/dose, but the majority were between 500 and 1000 mg/kg/dose, with a median of 800 mg/kg/dose. About 20% of the infants treated with IVIG showed late-onset anemia and required treatment. Adverse events were reported in less than 1% of infants. CONCLUSIONS For the treatment of BTHDN, IVIG administration was widely used in NICUs in Japan without severe adverse events.
