Abstract
INTRODUCTION Early-onset hyperbilirubinemia (EOH) is a clinical issue for premature infants. We predicted that EOH management would be improved by fast results from common laboratory tests. Total serum bilirubin (TSB) level and the albumin/globulin ratio may contribute to improving the management of EOH. OBJECTIVE The aim of the study is to examine the relationship between EOH and perinatal variables among infants born weighing 1,000 to 2,499 g. STUDY DESIGNS A single center study was undertaken at Ohta Nishinouchi Hospital between April 1, 2016 and January 31, 2022, using blood samples prospectively collected from infants admitted to the neonatal intensive care unit that were assessed by univariate analyses and multivariate logistic regression analysis. Due to a correlation between gestational age (GA) and birth weight (BW), each variable was entered separately into Model 1 (including GA) and 2 (including BW). RESULTS A total of 508 infants were analyzed (270 in the non EOH group and 238 in the EOH group). No infants experienced feto-maternal transfusion syndrome or hemolytic diseases such as blood type (ABO or Rh) incompatibility or glucose-6-phosphate dehydrogenase deficiency during perinatal period. Significant relationships were observed between EOH and BW (p <0.01, odds ratio [OR], 0.997; 95% confidence interval [CI], 0.996-0.997), albumin (p <0.01, OR, 0.278; 95% CI, 0.129-0.599), albumin/globulin ratio (p <0.01, OR, 2.695; 95% CI, 1.378-5.270), TSB (p <0.01, OR, 2.774; 95% CI, 1.795-4.287), and antenatal corticoid therapy (p = 0.02, OR, 1.852; 95% CI, 1.108-3.097) in Model 2. Per receiver operating characteristic curves, an albumin/globulin ratio of 1.84 could predict EOH at a sensitivity of 50.0% and specificity of 75.6% (AUC = 0.652, p <0.01, 95% CI, 0.603-0.700). CONCLUSION Albumin/globulin ratio among infants born weighing 1,000 to 2,499 g may be a useful indicator of EOH. KEY POINTS · Early-onset hyperbilirubinemia (EOH) is a clinical issue for premature infants.. · EOH management expected to be improved through the use of common laboratory tests.. · Albumin/globulin ratio among low birth weight infants may be a useful indicator of EOH..

Abstract
BACKGROUND Neonatal hyperbilirubinemia is one of the most common conditions for neonate inpatients. Indonesia faces a major challenge in which different guidelines regarding the management of this condition were present. This study aimed to compare the existing guidelines regarding prevention, diagnosis, treatment and monitoring in order to create the best recommendation for a new hyperbilirubinemia guideline in Indonesia. METHODS Through an earlier survey regarding adherence to the neonatal hyperbilirubinemia guideline, we identified that three main guidelines are being used in Indonesia. These were developed by the Indonesian Pediatric Society (IPS), the Ministry of Health (MoH), and World Health Organization (WHO). In this study, we compared factors such as prevention, monitoring, methods for identifying, risk factors in the development of neonatal jaundice, risk factors that increase brain damage, and intervention treatment threshold in the existing guidelines to determine the best recommendations for a new guideline. RESULTS The MoH and WHO guidelines allow screening and treatment of hyperbilirubinemia based on visual examination (VE) only. Compared with the MoH and WHO guidelines, risk assessment is comprehensively discussed in the IPS guideline. The MoH guideline recommends further examination of an icteric baby to ensure that the mother has enough milk without measuring the bilirubin level. The MoH guideline recommends referring the baby when it looks yellow on the soles and palms. The WHO and IPS guidelines recommend combining VE with an objective measurement of transcutaneous or serum bilirubin. The threshold to begin phototherapy in the WHO guideline is lower than the IPS guideline while the exchange transfusion threshold in both guidelines are comparably equal. CONCLUSIONS The MoH guideline is outdated. MoH and IPS guidelines are causing differences in approaches to the management hyperbilirubinemia. A new, uniform guideline is required.

Abstract
OBJECTIVE We analyze phototherapy rates after implementation of a Hyperbilirubinemia Clinical Pathway (HCP), which placed full-term ABOi DAT negative newborns on the low risk phototherapy nomogram, rather than medium risk, as previously done. STUDY DESIGN A chart review was performed for ABOi newborns born ≥36 weeks gestation between January 2020 and October 2021. Primary outcome measures were rates of phototherapy across pre- and post-intervention groups and among DAT negative newborns. RESULTS There was an increased proportion of newborns assigned to the low risk curve after the intervention. There were no significant differences in phototherapy rates among the intervention groups, although there was a non-significant decrease in phototherapy rates among DAT negative newborns after the intervention. There were no increases in adverse outcomes. CONCLUSIONS Providers adhered to the guidelines after implementation of the HCP. ABOi DAT negative newborns can be viewed as low risk for hyperbilirubinemia requiring phototherapy.

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
Jaundice caused by hyperbilirubinaemia is a common phenomenon during the neonatal period. Population-based studies evaluating assessment, management, and incidence of jaundice and need for phototherapy among otherwise healthy neonates are scarce. We prospectively explored these aspects in a primary care setting via assessing care as usual during the control phase of a stepped wedge cluster randomised controlled trial.We conducted a prospective cohort study embedded in the Screening and TreAtment to Reduce Severe Hyperbilirubinaemia in Infants in Primary care (STARSHIP) Trial. Healthy neonates were included in seven primary care birth centres (PCBCs) in the Netherlands between July 2018 and March 2020. Neonates were eligible for inclusion if their gestational age was ≥ 35 weeks, they were admitted in a PCBC for at least 2 days during the first week of life, and if they did not previously receive phototherapy. Outcomes were the findings of visual assessment to detect jaundice, jaundice incidence and management, and the need for phototherapy treatment in the primary care setting.860 neonates were included of whom 608 (71.9%) were visibly jaundiced at some point during admission in the PCBC, with 20 being 'very yellow'. Of the latter, four (20%) did not receive total serum bilirubin (TSB) quantification. TSB levels were not associated with the degree of visible jaundice (p = 0.416). Thirty-one neonates (3.6%) received phototherapy and none received an exchange transfusion. Five neonates did not receive phototherapy despite having a TSB level above phototherapy threshold.Jaundice is common in otherwise healthy neonates cared for in primary care. TSB quantification was not always performed in very jaundiced neonates, and not all neonates received phototherapy when indicated. Quality improvement initiatives are required, including alternative approaches to identifying potentially severe hyperbilirubinaemia.Trial registration: NL6997 (Dutch Trial Register; Old NTR ID 7187), registered 3 May 2018.

Abstract
OBJECTIVES To characterize the outcomes of ABO incompatible direct antiglobulin test (DAT) positive newborns and determine the predictive ability of a sixth-hour transcutaneous bilirubin (TcB for needing phototherapy ≤24 hours of age. METHODS Retrospective, cross-sectional study from May 2013 to March 2017. Of 10 942 consecutive newborns ≥35 weeks estimated gestational age, 829 were ABO incompatible and DAT positive. After excluding for antibodies other than ABO (51), missing data (4), miscategorization of blood type O (1), and duplicate record (1), 772 newborns remained. Of 772, a subsample of 346 newborns with both TcB and total serum bilirubin (TSB) tests within 1 hour of the sixth hour was analyzed to determine the predictive ability. RESULTS Phototherapy was required in 281 of 772 (36.4%); 156 (20.2%) in the first 24 hours. There were 10 (1.3%) admissions for hyperbilirubinemia to the NICU for intravenous immunoglobin. Birth weight, infant blood type B, TSB, reticulocyte count, and TcB were all significantly associated with phototherapy ≤24 hours. On multivariate analysis, significant predictors of phototherapy ≤24 hours were TSB and reticulocyte count if no TcB was done and TcB alone if no blood tests were done. TcB was highly predictive (odds ratio 3.1, 95% confidence interval: 2.4-4.0) and nearly as accurate as the TSB and reticulocyte count (area under the curve, 0.90 and 0.96, respectively). Low (<3.0 mg/dL) and high (≥5.3 mg/dL) risk TcB cutoffs demonstrated a negative predictive value of 98% and positive predictive value of 85%, respectively. CONCLUSIONS Among high-risk ABO incompatible DAT positive newborns, the sixth-hour TcB is highly predictive of the need for phototherapy ≤24 hours.

Abstract
BACKGROUND Neonatal jaundice occurs in approximately 60% of term newborns. Although risk factors for neonatal jaundice have been studied, all the suggested strategies are based on various newborn tests for bilirubin levels. We aim to stratify neonates into risk groups for clinically significant neonatal jaundice using a combined data analysis approach, without serum bilirubin evaluation. STUDY DESIGN Term (gestational week 37-42) neonates born in a single medical center, 2005-2018 were identified. Anonymized data were analyzed using machine learning. Thresholds for stratification into risk groups were established. Associations were evaluated statistically using neonates with and without clinically significant neonatal jaundice from the study population. RESULTS A total of 147,667 consecutive term live neonates were included. The machine learning diagnostic ability to evaluate the risk for neonatal jaundice was 0.748; 95% CI 0.743-0.754 (AUC). The most important factors were (in order of importance) maternal blood type, maternal age, gestational age at delivery, estimated birth weight, parity, CBC at admission, and maternal blood pressure at admission. Neonates were then stratified by risk: 61% (n = 90,140) were classed as low-risk, 39% (n = 57,527) as higher-risk. Prevalence of jaundice was 4.14% in the full cohort, and 1.47% and 8.29% in the low- and high-risk cohorts, respectively; OR 6.06 (CI: 5.7-6.45) for neonatal jaundice in high-risk group. CONCLUSION A population tailored "first step" screening policy using machine learning model presents potential of neonatal jaundice risk stratification for term neonates. Future development and validation of this computational model are warranted.

Abstract
OBJECTIVES The purpose of this study was to minimize unnecessary laboratory services for hospitalized neonates with hyperbilirubinemia by revising a local clinical practice pathway (CPP). METHODS A retrospective cohort study was performed to compare the number of laboratory tests and blood draws in patients hospitalized with neonatal hyperbilirubinemia before and after implementation of a revised CPP. The study included infants with neonatal hyperbilirubinemia <14 days old admitted after their birth hospitalization between April 2017 and October 2019. Primary outcome measures included the total number of blood draws and the number of laboratory tests obtained per patient and length of stay. Secondary outcome measures included 7-day readmission rate, charges, and discharge bilirubin level. RESULTS The median number of blood draws per patient after implementation of the CPP decreased to 2 (interquartile range [IQR], 2-3) compared with 3 (IQR, 2-3) before implementation (Poisson model-based estimated mean difference, 1.1; 95% confidence interval, 1.0-1.3; P = .018). The median number of laboratory tests per patient after implementation decreased from 4 (IQR, 3-6) to 3 (IQR, 2-4; Poisson model-based estimated mean difference, 1.3; 95% confidence interval, 1.2-1.5; P < .0001). There was no significant change in length of stay, readmission rate, charges, or discharge bilirubin level. CONCLUSIONS Implementation of a revised CPP was associated with a significant decrease in the number of blood draws and laboratory tests per patient for infants admitted to the hospital for neonatal hyperbilirubinemia.

Abstract
OBJECTIVE To develop a statistically rigorous, hour-specific bilirubin nomogram for newborns based on a very large data set; and use it prospectively as a replacement for the 1999 Bhutani nomogram. STUDY DESIGN This was a retrospective analysis of first total serum bilirubin (TSB) measurements from 15 years of universal bilirubin screening during birth hospitalizations at 20 Intermountain Healthcare hospitals. Hour-specific TSB values were assembled into a nomogram by percentile, and subgroups were compared. RESULTS The information obtained included robust data in the first 12 hours after birth (which was not included in the 1999 nomogram), general agreement with the 1999 nomogram for values in the first 60 hours, but higher 75th and 95th percentile TSB values thereafter in the new version, no difference in TSB between male and female infants, higher TSB values among earlier gestation neonates (350/7-366/7 weeks vs ≥37 weeks, P < .0001), and lower TSB values in neonates of Black race (P < .0001) and higher values in neonates of Asian race (P < .001). CONCLUSIONS An updated and more informative Bhutani neonatal bilirubin nomogram, based on 140 times the number of subjects included the 1999 version, is now in place in our health care system.

Abstract
This article attempts to highlight contemporary issues relating to term neonatal hyperbilirubinemia and to focus attention on controversial issues and concepts with the potential to effect change in clinical approach. On the one hand, the focus is bilirubin neurotoxicity, which is now known to encompass a wide, diverse spectrum of features. The various aspects of this spectrum are outlined and defined. On the other hand, bilirubin also possesses antioxidant properties. As such, mild hyperbilirubinemia is suggested as actually offering the neonate some protective advantage.

Abstract
AIM This study aimed to investigate the effect of adding ursodeoxycholic acid (UDCA) to phototherapy in neonates with glucose-6-phosphate dehydrogenase (G6PD) deficiency and hyperbilirubinaemia. G6PD deficiency is a common cause of severe hyperbilirubinaemia in neonates. METHODS This study was a triple blind, clinical trial study of 40 neonates with G6PD deficiency and hyperbilirubinaemia who admitted for phototherapy in hospitals affiliated to the University of Medical Sciences. The treatment group (n = 20) received UDCA 10 mg/kg (2 cc/kg) daily divided into 2 doses every 12 h. The control group (n = 20) received the same volume of placebo syrup. The drug and placebo treatments were continued until the bilirubin level dropped below 171 μmol/L. Both the control and treatment group received continuous phototherapy. Independent sample t-test, survival analysis and logrank test were used to statistically analyse the results. RESULTS The mean total bilirubin level was 231.9 ± 18.8 μmol/L and 184.3 ± 18.6 μmol/L in the control and intervention group respectively, 24 h after drug administration and 209.7 ± 19.3 μmol/L and 157.4 ± 16.4 μmol/L, respectively, 48 h after intervention (P < 0.05). The median length of hospitalisation in the treatment group was approximately 1 day lower than the control group (logrank test P value: <0.001). CONCLUSION The study showed that the addition of UDCA to phototherapy accelerates the reduction of total bilirubin level in neonates with G6PD deficiency and can reduce the duration of hospitalisation.

Abstract
PURPOSE To analyze the short-term survival of the nursing diagnosis of neonatal hyperbilirubinemia in hospitalized neonates within the first 24 h of life and over a maximum of 7 days. METHODS A prospective open cohort study with a longitudinal design was developed with 120 newborns during the first 24 h of life. The survival rate after a nursing diagnosis of neonatal hyperbilirubinemia was analyzed for 7 days. FINDINGS The number of new cases of neonatal hyperbilirubinemia during the follow-up was 82 (RR: 90.1%, daily incidence rate: 34.17%). The greatest manifestation of the diagnosis occurred in the first three days (n = 97). The median diagnostic survival time was 2 days (95% CI: 2-2). Yellow-orange skin color (RR = 8.08), yellow mucous membranes (RR = 2.05), yellow sclera (RR = 1.99), and female gender (RR = 1.36) had the highest risk ratios. CONCLUSIONS A rapid impairment of neonatal hyperbilirubinemia in hospitalized neonates was observed. Some clinical indicators were associated with an increased risk for this diagnosis. IMPLICATIONS FOR NURSING PRACTICE Studies on the prognostic capacity of the clinical indicators of nursing diagnoses like neonatal hyperbilirubinemia strengthen the clinical reasoning of nurses and subsidize diagnostic inferences and accurate clinical decisions.

Abstract
BACKGROUND AND OBJECTIVES Bilirubin screening before discharge is performed to identify neonates at risk for future hyperbilirubinemia. The American Academy of Pediatrics recommends using a graph of bilirubin levels by age (the Bhutani Nomogram) to guide follow-up and a different graph to determine phototherapy recommendations. Our objective was to evaluate predictive models that incorporate the difference between the last total serum bilirubin (TSB) before discharge and the American Academy of Pediatrics phototherapy threshold (Δ-TSB) to predict a postdischarge TSB above the phototherapy threshold by using a single graph. METHODS We studied 148 162 infants born at ≥35 weeks' gestation at 11 Kaiser Permanente Northern California facilities from 2012 to 2017 whose TSB did not exceed phototherapy levels and who did not receive phototherapy during the birth hospitalization. We compared 3 logistic models (Δ-TSB; Δ-TSB-Plus, which included additional variables; and the Bhutani Nomogram) by using the area under the receiver operating characteristic curve (AUC) in a 20% validation subset. RESULTS A total of 2623 infants (1.8%) exceeded the phototherapy threshold postdischarge. The predicted probability of exceeding the phototherapy threshold after discharge ranged from 56% for a predischarge Δ-TSB 0 to 1 mg/dL below the threshold to 0.008% for Δ-TSB >7 mg/dL below the threshold. Discrimination was better for the Δ-TSB model (AUC 0.93) and the Δ-TSB-Plus model (AUC 0.95) than for the Bhutani Nomogram (AUC 0.88). CONCLUSIONS The use of Δ-TSB models had excellent ability to predict postdischarge TSB above phototherapy thresholds and may be simpler to use than the Bhutani Nomogram.

Abstract
BACKGROUND AND OBJECTIVE Due to selection bias and other issues, the only available serum bilirubin-based nomogram does not reflect the natural history of early neonatal bilirubinemia. Our objective was to obtain a global picture of the natural history of early post-natal bilirubin trajectories. STUDY DESIGN We pooled readings from 19 published transcutaneous bilirubin nomogram reports including many newborns at multiple sites. We constructed a universal transcutaneous bilirubin nomogram which included the 25th, 50th, 75th, and 95th percentiles from 12 to 120 h. RESULTS The global transcutaneous bilirubin nomogram included >119,000 readings from 44,392 apparently normal, predominantly breastfed newborns ≥35 weeks gestation. The pooled transcutaneous bilirubin trajectories increased during the first 3 post-natal days, and peaked or plateaued between the 3rd and 4th days. CONCLUSIONS We provide the first globally derived transcutaneous bilirubin nomogram that reflects the natural history of early neonatal bilirubinemia in neonates ≥35 weeks gestation.

Abstract
IMPORTANCE Kernicterus is a devastating, permanently disabling neurologic condition resulting from bilirubin neurotoxicity. Black neonates account for more than 25% of kernicterus cases in the US, despite making up only approximately 14% of all births. This is a largely overlooked health disparity. OBSERVATIONS The black kernicterus health disparity exists despite a lower overall incidence of clinically significant hyperbilirubinemia among black neonates, a paradox recently explained by a previously unrecognized risk for hazardous hyperbilirubinemia. Aligned with national and global health initiatives to reduce or eliminate health disparities, this review highlights the multiple biologic and nonbiologic factors contributing to kernicterus risk in black infants and approaches to reduce this health disparity. This includes both parent-level and clinician-level kernicterus prevention strategies, with an emphasis on improving parental health literacy on neonatal jaundice and acute bilirubin encephalopathy and clinician awareness of the key factors that contribute to hazardous hyperbilirubinemia risk in this vulnerable group. Parent-level prevention strategies include efforts to improve their health literacy on neonatal jaundice and acute bilirubin encephalopathy and empower care seeking for jaundice. Clinician-level prevention strategies include efforts to eliminate community and institutional barriers that impede access to care, heighten clinician awareness of the factors that contribute to kernicterus risk in this vulnerable patient group, and strengthen newborn hyperbilirubinemia management and bilirubin surveillance. CONCLUSIONS AND RELEVANCE There are multiple opportunities for intervention to reduce black kernicterus risk. Although kernicterus is a rare disorder, the incidence among black infants is not a trivial matter nor are efforts to prevent kernicterus. While the multiple interacting biologic and nonbiologic contributors to increased kernicterus risk among black infants pose a considerable challenge to clinicians, there are opportunities for intervention to reduce this risk and health disparity. Continued study is imperative to understand the current scope of kernicterus and its occurrence in black neonates.

Abstract
BACKGROUND Early identification and appropriate follow-up of infants at risk of severe hyperbilirubinemia are part of preventing complications. This study aims to develop the clinical predictive score to predict subsequent severe hyperbilirubinemia in healthy Thai infants. METHODS A case-control study was conducted using medical records of 147 hyperbilirubinemia cases and 147 age-matched controls among healthy late preterm and term Thai newborn infants during January 2015 and December 2016. The routinely measured TcB values at 48-54 hours of age and all predischarge clinical characteristics were collected. Multivariable logistic regression was used to find a clinical prediction model to predict subsequent severe hyperbilirubinemia within 7 days after birth which defined as a postdischarge bilirubin level exceeding the hour-specific recommended threshold for phototherapy by the American Academy of Pediatrics (AAP). RESULTS The best clinical predictors for subsequent severe hyperbilirubinemia were TcB values at 48-54 hours and gestational age of infants. Predischarge TcB at 48-54 hours of life was classified into 3 levels: < 10 mg/dL, 10-12 mg/dL and > 12 mg/dL. Gestational age was categorized into 5 groups. The risk score derived from these 2 significant factors predicted subsequent severe hyperbilirubinemia with an AuROC curve of 81.0% (95% CI: 76.2-85.9%) in 3 risk group, high, moderate and low. The positive likelihood ratio for subsequent severe hyperbilirubinemia of the high-risk group (score > 5) was 4.53 (95% CI: 2.91-7.04) with specificity of 87.1%. The negative predictive value of low-risk group (score < 3) was 81%. CONCLUSIONS A simple predischarge prediction score using gestational age and TcB values at 48-54 hours of life was developed. This score classified late preterm and term newborn infants into 3 distinct risk levels and may be useful to identify high-risk infants for outpatient follow-up of subsequent severe hyperbilirubinemia.

Abstract
A breakthrough discovery 60 years ago by Cremer et al. has since changed the way we treat infants with hyperbilirubinemia and saved the lives of millions from death and disabilities. "Photobiology" has evolved by inquiry of diverse light sources: fluorescent tubes (wavelength range of 400-520 nm; halogen spotlights that emit circular footprints of light; fiberoptic pads/blankets (mostly, 400-550 nm range) that can be placed in direct contact with skin; and the current narrow-band blue light-emitting diode (LED) light (450-470 nm), which overlaps the peak absorption wavelength (458 nm) for bilirubin photoisomerization. Excessive bombardment with photons has raised concerns for oxidative stress in very low birthweight versus term infants treated aggressively with phototherapy. Increased emphasis on prescribing phototherapy as a "drug" that is dosed cautiously and judiciously is needed. In this historical review, we chronicled the basic to the neurotoxic components of severe neonatal hyperbilirubinemia and the use of standardized interventions.

Abstract
OBJECTIVES To assess whether arterial umbilical cord bilirubin (aUCB) level at delivery predicts predischarge neonatal hyperbilirubinemia, facilitating a safe discharge from the hospital. METHODS Prospective analysis of hospital biochemistry records identified near term and term infants with recorded aUCB and predischarge, at 36 h of life, capillary heal bilirubin (cHB), to identify those with a cutoff of bilirubin levels >9 mg/ml, >75th percentile on the nomogram of Bhutani et al. RESULTS Of 616 study neonates, median (IQR) aUCB and cHB levels were 1.5 mg % (IQR 0.7-2.2) and 7.7 mg % (IQR 6.6-8.9), respectively. The values resulted statistically correlated (Pearson correlation coefficient 0.26, p < .0001) and an increment of 1 mg/dl in aUCB was associated with an increment (Regression coefficient, 95% confidence interval) of mean cHB 0.49 (0.33-0.65, p < .0001). Among these, 143 (23.2%) neonates developed bilirubin levels >9 mg/ml at 36 h of life and multivariable analysis confirmed that cHB levels (OR 1.49, 95% CI 1.22-1.82; p < .0001) and vaginal delivery (OR 2.34, 95% CI 1.33-4.36; p = .005) were significantly associated with bilirubin levels >9 mg/ml. CONCLUSIONS These data suggest that aUCB should be added to the list of major risk factors for neonatal hyperbilirubinemia.

Abstract
Neonatal hyperbilirubinemia is one of the most frequent diagnoses made in neonates. A high level of unconjugated bilirubin that is unbound to albumin is neurotoxic when the level exceeds age-specific thresholds or at lower levels in neonates with neurotoxic risk factors. Lower range of unbound bilirubin results in apoptosis, while moderate-to-high levels result in neuronal necrosis. Basal ganglia and various brain stem nuclei are more susceptible to bilirubin toxicity. Proposed mechanisms of bilirubin-induced neurotoxicity include excessive release of glutamate, mitochondrial energy failure, release of proinflammatory cytokines, and increased intracellular calcium concentration. These mechanisms are similar to the events that occur following hypoxic-ischemic insult in neonates. Severe hyperbilirubinemia in term neonates has been shown to be associated with increased risk for autism spectrum disorders. The neuropathological finding of bilirubin-induced neurotoxicity also includes cerebellar injury with a decreased number of Purkinje cells, and disruption of multisensory feedback loop between cerebellum and cortical neurons which may explain the clinical characteristics of autism spectrum disorders. Severe hyperbilirubinemia occurs more frequently in infants from low- and middle-income countries (LMIC). Simple devices to measure bilirubin, and timely treatment are essential to reduce neurotoxicity, and improve outcomes for thousands of neonates around the world.

Abstract
Background Newborn hyperbilirubinemia is considered a worldwide health problem that demands medical evaluation. Noninvasive transcutaneous bilirubin (TcB) has been used as a screening method with different devices but there has not been any evaluation of reproducibility of the same brand devices. The BiliCare™ system is evaluated to demonstrate consistency between measurements with four different devices. Methods 336 TcB measurements were obtained with four BiliCare™ devices in 21 Mexican icteric newborns with a mean postnatal age of 44.1 hours of life and 38 weeks of gestation (33–41). Two measurements were taken in the same ear alternatively at the scaphoid fossa with each device. TcB values were compared between devices. Validity was compared with total serum bilirubin (TB). Results intraclass correlation coefficient demonstrates a minimum limit in the study of 0.945 and maximum of 0.988 with the same device. Correlations with serum and between devices gave results above 0.932. Conclusions BiliCare™ transcutaneous bilirubin measurement instrument has very good intra- and interdevice reproducibility; also correlation of TcS with serum bilirubin gave statistically the same results.

Abstract
Severe hyperbilirubinemia, which may result in kernicterus, is seen more frequently in low and middle-income countries, such as Indonesia, than in high-income countries. In Indonesia midwives, general practitioners (GPs), and pediatricians are involved in the care of jaundiced newborn infants. It is unknown whether the high incidence of severe hyperbilirubinemia in this country is related to a lack of awareness of existing hyperbilirubinemia guidelines issued by, for example, the World Health Organization, the American Academy of Pediatrics, or the Indonesian Health Ministry, or to a lack of adherence to such guidelines. The aim of this questionnaire study was to assess health professionals’ awareness of existing guidelines and their adherence to these guidelines in daily practice. We handed out a ten-question questionnaire to midwives, GPs, and pediatricians that included questions about the professionals themselves as well as clinical questions. The midwives completed 291 questionnaires, the GPs 206, and the pediatricians 154, all of which we used for our analysis. Almost 30% of the midwives and 23% of the GPs were either unaware of any existing guidelines or they did not adhere to them. Only 54% of the midwives recognized the warning signs of severe hyperbilirubinemia correctly, compared to 68% of the GPs and 89% of the pediatricians. Twenty-eight percent of the midwives and 31% of the GPs indicated that their first follow-up visit was after 72 hours, while 90% of them discharged infants after less than 48 hours after birth. The awareness of and adherence to guidelines for preventing and treating hyperbilirubinemia is low amongst the midwives and GPs in Indonesia. This may be an important contributing factor in the high incidence of severe hyperbilirubinemia in Indonesia.

Heme oxygenase-1 genetic variants and the conundrum of hyperbilirubinemia in African-American newborns. J Perinatol 2018; 38:345-350. [PMID: 29302043 DOI: 10.1038/s41372-017-0039-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2017] [Revised: 12/05/2017] [Accepted: 12/12/2017] [Indexed: 11/09/2022]
Abstract
BACKGROUND African-American (AA) infants are known to have, overall, lower bilirubin levels than infants of other ethnicities during their birth hospitalization. However, they are known to have a higher incidence of severe hyperbilirubinemia and are over represented in the US Kernicterus Registry. Heme oxygenase-1 (HO) is the rate limiting enzyme in heme metabolism leading to the equimolar production of bilirubin, carbon monoxide (CO) and free iron (Fe). Short (S) (GT)n repeats (<25) in the promoter region of the gene encoding the inducible HO-1 isozyme augment its expression, while long (L) repeats (>33) lead to an attenuation, modulating the production of bilirubin and CO. The impact of HO-1 promoter polymorphisms on bilirubin levels has not been well studied in (AA) infants. OBJECTIVE The objectives of this study were to compare the distribution of (GT)n repeat lengths in the HO-1 promoter region in a cohort of AA infants to those found in other ethnicities and to evaluate the contribution of this polymorphism to the degree of hyperbilirubinemia and the level of COHbc in this cohort. METHODS We prospectively studied a cohort of term AA infants with O+ mothers. Per hospital routine, infants' blood type, Rh status, direct antiglobulin test (DAT), and total bilirubin (TB) levels were checked prior to discharge. After parental consent, blood was collected for DNA extraction and carboxyhemoglobin (COHbc) measurements at the same time as the infants' newborn screen. An infant's TB percentile risk based on the Bhutani nomogram was used to determine need for phototherapy or follow-up. (GT)n repeat length in the HO-1 promoter was determined for each allele using PCR after DNA extraction from dried bloodspots. Size of allele lengths were typed as short (S, <25), medium (M, 25-33) or long (L, >33). RESULTS One hundred eighty infants were studied for a total of 360 separate alleles. 12.2% (44/360) of alleles were S which was significantly less than all other ethnicities reviewed. Carboxyhemoglobin (COHbc) levels and bilirubin percentiles were higher among infants who had at least one S allele when compared to those who had at least one L allele in the cohort as a whole: COHbc 0.92 ± 0.35 vs. 0.85 ± 0.37; p = 0.28 and Bilirubin percentile 48.6 ± 34.0 vs. 44.9 ± 31.6; p = 0.51. This relationship remained when only those infants who were DAT neg were examined: COHbc 0.81 ± 0.26 vs. 0.74 ± 0.21; p = 0.11 and Bilirubin percentile 43.6 ± 29.9 vs. 37.5 ± 28.7; p = 0.28. CONCLUSIONS The presence of L alleles of this variant is significantly greater among infants who are either African or of African descent. There was a trend toward lower COHbc levels among infants with at least one L allele as opposed to at least one S allele, although this did not have a statistically significant impact on TB risk percentile.

Abstract
BACKGROUND The recognition, follow-up, and early treatment of neonatal jaundice has become more difficult, since the earlier discharge of newborns from hospitals has become common practice. Since intrapartum hypoxic stress has been pointed as predisposing factor for the occurrence of hyperbilirubinemia risk, we tested the association with the cord blood acid-base index tests. METHODS A cohort of healthy term and near-term newborns underwent umbilical cord hemogasanalysis at birth and capillary heel total serum bilirubin (TSB) pre-discharge, scheduled at 36 h of life, to define the risk of significant hyperbilirubinemia, defined as >9 mg/dL TSB level, ≥ 75th percentile on nomogram of Bhutani et al. RESULTS It was found that among 537 studied neonates, 133 (24.8%) had pre-discharge TSB levels of >9 mg/dL. When the cord blood gas analysis index tests were compared, their acidemia levels were significantly higher than those of neonates with normal TSB levels: HCO3- (20.71 ± 2.37 vs. 21.29 ± 2.25 mEq/L, p < 0.010), base deficit (-3.52 ± 3.188 vs. -2.68 ± 3.266 mEq/L, p < 0.010), and lactacidemia (3.84 ± 1.864 vs. 3.39 ± 1.737 mEq/L, p < 0.012), respectively. However, logistic regression analysis showed that base deficit was the strongest index of the pre-discharge hyperbilirubinemia risk (OR, 95% CI 0.593; 0.411-0.856), and the hyperbilirubinemia risk increased by 40% with the decrease of 1 mEq/L of base deficit. CONCLUSIONS Umbilical cord blood acidemia and lactacidemia are significant indexes of adaptive mechanisms at birth. The base deficit provides the strongest association with future development of high bilirubin on an hour specific bilirubin nomogram generating risk stratification score in term and near-term neonates.

Abstract
Hyperbilirubinaemia is one of the most frequent causes of hospital readmission during the first week of life. Its detection is still a big challenge, mainly due to the early discharge from the hospital that can be associated with a delay of the diagnosis. The identification of those newborns at risk of developing significant hyperbilirubinaemia is one of the main priorities in the public health care system. An approach to the management of newborn jaundice is presented in this article, following the recommendations based on the medical evidence and on the opinion of the Standards Committee of the Spanish Society of Neonatology.

Abstract
OBJECTIVE We aimed to develop a transcutaneous bilirubin (TcB) nomogram for assessment of the risk of significant hyperbilirubinemia and prolonged jaundice during the first month of life in term and late-preterm Turkish newborns. METHODS On the basis of the daily (3rd, 7th, 15th and 30th days) TcB measurements, 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentiles, and 5 percentile tracks were obtained. TcB measurements were made by a transcutaneous bilirubinometer (JaundiceDetector JH20-1C). RESULTS We screened 729 healthy term and late-preterm Turkish infants 3-30 days old and developed a nomogram of TcB levels. TcB level was ≥5 mg/dl in 41.98% and 25.9% of infants at age 15.0 ± 2.1 days and 30.9 ± 2.6 days, respectively. The TcB measurement-based nomogram values of the 97th percentiles (cutoff values) at age 15.0 ± 2.1 and 30.9 ± 2.6 days were 11.4 (10.82-12.13) mg/dl and 10.0 (9.40-10.70) mg/dl, respectively. CONCLUSION This nomogram can be used to determine the risk status of Turkish newborns regarding significant hyperbilirubinemia and prolonged jaundice on the basis of TcB measurement in the first month of life.

Abstract
Criteria for newborn hospital discharge have to include physiological stability and family competence to provide newborn care at home. In this document, the Committee of Standards of the Spanish Society of Neonatology reviews the minimum criteria to be met before hospital discharge of a term newborn infant. We include a review of hospital discharge criteria for the late preterm infants, as these infants are often not hospitalised and remain with their mother after birth. A shortened hospital stay (less than 48h after delivery) for healthy term newborns can be considered, but it is not appropriate for every mother and newborn. Newborn infants discharged before 48h of age, should be examined within 3-4 days of life.

Abstract
OBJECTIVE To evaluate the impact of statewide learning collaboratives that used national guidelines to manage jaundice on the serial prevalence of extreme hyperbilirubinemia (EHB, total bilirubin ⩾25 mg dl(-1)) and exchange transfusions introduced in California Perinatal Quality Care Collaborative (CPQCC) hospitals in 2007. STUDY DESIGN Adverse outcomes were retrieved from statewide databases on re-admissions for live births ⩾35 weeks' gestation (2007 to 2012) in diverse CPQCC hospitals. Individual and cumulative select perinatal risk factors and frequencies were the outcomes measures. RESULTS For 3 172 762 babies (2007 to 2012), 92.5% were ⩾35 weeks' gestation. Statewide EHB and exchange rates decreased from 28.2 to 15.3 and 3.6 to 1.9 per 100 000 live births, respectively. From 2007 to 2012, the trends for TB>25 mg dl(-1) rates were -0.92 per 100 000 live births per year (95% CI: -3.71 to 1.87, P=0.41 and R(2)=0.17). CONCLUSION National guidelines complemented by statewide learning collaboratives can decrease or modify outcomes among all birth facilities and impact clinical practice behavior.

Abstract
Humanized UDP-glucuronosyltransferase (UGT)-1 (hUGT1) mice encode the UGT1 locus including the UGT1A1 gene. During neonatal development, delayed expression of the UGT1A1 gene leads to hyperbilirubinemia as determined by elevated levels of total serum bilirubin (TSB). We show in this report that the redox-sensitive NF-κB pathway is crucial for intestinal expression of the UGT1A1 gene and control of TSB levels. Targeted deletion of IKKβ in intestinal epithelial cells (hUGT1/Ikkβ(ΔIEC) mice) leads to greater neonatal accumulation of TSB than observed in control hUGT1/Ikkβ(F/F) mice. The elevation in TSB levels in hUGT1/Ikkβ(ΔIEC) mice correlates with a reduction in intestinal UGT1A1 expression. As TSB levels accumulate in hUGT1/Ikkβ(ΔIEC) mice during the neonatal period, the increase over that observed in hUGT1/Ikkβ(F/F) mice leads to weight loss, seizures and eventually death. Bilirubin accumulates in brain tissue from hUGT1/Ikkβ(ΔIEC) mice inducing an inflammatory state as shown by elevated TNFα, IL-1β and IL-6, all of which can be prevented by neonatal induction of hepatic or intestinal UGT1A1 and lowering of TSB levels. Altering the redox state of the intestines by oral administration of cadmium or arsenic to neonatal hUGT1/Ikkβ(F/F) and hUGT1/Ikkβ(ΔIEC) mice leads to induction of UGT1A1 and a dramatic reduction in TSB levels. Microarray analysis following arsenic treatment confirms upregulation of oxidation-reduction processes and lipid metabolism, indicative of membrane repair or synthesis. Our findings indicate that the redox state in intestinal epithelial cells during development is important in maintaining UGT1A1 gene expression and control of TSB levels.

Abstract
BACKGROUND Before hospital discharge, newborn infants should be assessed for the risk of excessive hyperbilirubinemia. We determined maternal and obstetric risk factors for hyperbilirubinemia in infants born at term (gestational age ≥37 weeks) to form an individualized risk assessment tool for clinical use. METHODS This was a population-based study with data from the Swedish Medical Birth Register from 1999 to 2012, including 1,261,948 singleton infants. Outcome was defined as infants diagnosed with hyperbilirubinemia (N = 23,711), excluding all cases of hemolytic (immune-mediated or other specified hemolytic) diseases of the newborn. RESULTS Risk factors with an adjusted odds ratio (aOR) for neonatal hyperbilirubinemia of ≥1.5 (medium-sized effect or more) were gestational age 37 to 38 weeks (aOR = 2.83), failed vacuum extraction (aOR = 2.79), vacuum extraction (aOR = 2.22), Asian mother (aOR = 2.09), primipara (aOR = 2.06), large-for-gestational-age infant (aOR = 1.84), obese mother (aOR = 1.83), and small-for-gestational-age infant (aOR = 1.66). Planned cesarean delivery (CD) was associated with a reduced risk (aOR = 0.45). Without any of these risk factors (normal birth weight infant delivered vaginally at 39 to 41 weeks' gestation by a non-Asian, nonobese, multiparous mother) the rate of nonhemolytic neonatal hyperbilirubinemia was 0.7%. In relation to the combined load of different risk factors, rates of neonatal hyperbilirubinemia ranged from 0.2% to 25%. CONCLUSIONS Collection of a few easily available maternal and obstetric risk factors predicts >100-fold variation in the incidence of neonatal hyperbilirubinemia. The information provided herein enables individualized risk prediction with interactions between different risk factors taken into account.

Abstract
BACKGROUND AND OBJECTIVES Widespread newborn screening on a point-of-care basis could prevent bilirubin neurotoxicity in newborns with glucose-6-phosphate dehydrogenase (G6PD) deficiency. We evaluated a quantitative G6PD assay on a digital microfluidic platform by comparing its performance with standard clinical methods. METHODS G6PD activity was measured quantitatively by using digital microfluidic fluorescence and the gold standard fluorescence biochemical test on a convenience sample of 98 discarded blood samples. Twenty-four samples were designated as G6PD deficient. RESULTS Mean ± SD G6PD activity for normal samples using the digital microfluidic method and the standard method, respectively, was 9.7 ± 2.8 and 11.1 ± 3.0 U/g hemoglobin (Hb), respectively; for G6PD-deficient samples, it was 0.8 ± 0.7 and 1.4 ± 0.9 U/g Hb. Bland-Altman analysis determined a mean difference of -0.96 ± 1.8 U/g Hb between the digital microfluidic fluorescence results and the standard biochemical test results. The lower and upper limits for the digital microfluidic platform were 4.5 to 19.5 U/g Hb for normal samples and 0.2 to 3.7 U/g Hb for G6PD-deficient samples. The lower and upper limits for the Stanford method were 5.5 to 20.7 U/g Hb for normal samples and 0.1 to 2.8 U/g Hb for G6PD-deficient samples. The measured activity discriminated between G6PD-deficient samples and normal samples with no overlap. CONCLUSIONS Pending further validation, a digital microfluidics platform could be an accurate point-of-care screening tool for rapid newborn G6PD screening.

Abstract
OBJECTIVES To develop and validate a predischarge risk stratification model by using transcutaneous bilirubin (TcB) values and clinical factors to predict significant postdischarge hyperbilirubinemia in healthy term and late preterm Chinese neonates. METHODS In a prospective cohort study, 8215 healthy term and late preterm neonates in 8 hospitals in China underwent TcB measurement at <168 hours of age. TcB percentiles were calculated and used to develop an hour-specific nomogram, and 9 empirically weighted items were used to derive a prediction model. A risk stratification model was developed by combining the TcB nomogram with clinical risk scores to predict significant hyperbilirubinemia, defined as a postdischarge bilirubin level that exceeded the hour-specific recommended threshold value for phototherapy. Data from another 13,157 neonates were used to validate the model. RESULTS A TcB nomogram for every 12 hours of the studied interval was constructed from the development set. Gestational age, male gender, history of previous neonate who received phototherapy, bruising, feeding mode, weight loss, and early discharge were predictors of postdischarge significant hyperbilirubinemia. The combination of the TcB nomogram and clinical risk score provided the best prediction of significant hyperbilirubinemia with an area under the curve of 0.95 (95% confidence interval: 0.94-0.95) in the development data set and 0.94 (95% confidence interval: 0.93-0.94) in the validation data set. A risk stratification model with 6 distinct risk levels was developed and validated. CONCLUSIONS A risk classification model, combining discharge transcutaneous bilirubin values and clinical risk factors, separated term and late preterm Chinese neonates into 6 risk classes for the timely follow-up of postdischarge hyperbilirubinemia detection.

Abstract
OBJECTIVES To examine the association between early discharge from hospital after birth and readmission to hospital for jaundice among term infants, and among infants discharged early, to investigate the perinatal risk factors for readmission for jaundice. METHODS Birth data for 781,074 term live-born infants born in New South Wales, Australia from 2001 to 2010 were linked to hospital admission data. Logistic regression models were used to investigate the association between postnatal length of stay (LOS), gestational age (GA), and readmission for jaundice in the first 14 days of life. Other significant perinatal risk factors associated with readmission for jaundice were examined for infants discharged in the first 2 days after birth. RESULTS Eight per 1000 term infants were readmitted for jaundice. Infants born at 37 weeks' GA with an LOS at birth of 0 to 2 days were over 9 times (adjusted odds ratio [aOR] 9.43; 95% CI, 8.34-10.67) and at 38 weeks' GA were 4 times (aOR 4.05; 95% CI, 3.62-4.54) more likely to be readmitted for jaundice compared with infants born at 39 weeks' GA with an LOS of 3 to 4 days. Other significant risk factors for readmission for jaundice for infants discharged 0 to 2 days after birth included vaginal birth, born to mothers from an Asian country, born to first-time mothers, or being breastfed at discharge. CONCLUSIONS This study can inform guidelines or policy about identifying infants at risk for readmission for jaundice and ensure that appropriate post-discharge follow-up is received.

Abstract
Although the modern era of transcutaneous bilirubin monitoring (TcB) began only about 35 years ago, this screening tool is now widely used in newborn nurseries and outpatient clinics, offices, and emergency departments to obtain a rapid and non-invasive estimate of the degree of hyperbilirubinemia. TcB devices have become more sophisticated, and major breakthroughs include the following: (a) ability to report a bilirubin value rather than an index value, (b) enhanced correction for chromophores other than bilirubin, and (c) technologic improvements including interface with electronic medical records. Good agreement with laboratory bilirubin measurement has been demonstrated, and the ability of TcB screening to predict and decrease the incidence of subsequent hyperbilirubinemia has been well-documented. To date, it has not been shown that this screening results in improved long-term outcomes.

Abstract
BACKGROUND Hyperbilirubinemia occurs in most healthy term and late-preterm infants, and must be monitored to identify those who might develop severe hyperbilirubinemia. Total serum bilirubin (TSB) or transcutaneous bilirubin (TcB) nomograms have been developed and validated to identify neonatal hyperbilirubinemia. This study aimed to review previously published studies and compare the TcB nomograms with the TSB nomogram, and to determine if the former has the same predictive value for significant hyperbilirubinemia as TSB nomogram does. METHODS A predefined search strategy and inclusion criteria were set up. We selected studies assessing the predictive ability of TSB/TcB nomograms to identify significant hyperbilirubinemia in healthy term and late-preterm infants. Two independent reviewers assessed the quality and extracted the data from the included studies. Meta-Disc 1.4 analysis software was used to calculate the pooled sensitivity, specificity, and positive likelihood ratio of TcB/TSB nomograms. A pooled summary of the receiver operating characteristic of the TcB/TSB nomograms was created. RESULTS After screening 187 publications from electronic database searches and reference lists of eligible articles, we included 14 studies in the systematic review and meta-analysis. Eleven studies were of medium methodological quality. The remaining three studies were of low methodological quality. Seven studies evaluated the TcB nomograms, and seven studies assessed TSB nomograms. There were no differences between the predictive abilities of the TSB and TcB nomograms (the pooled area under curve was 0.819 vs. 0.817). CONCLUSIONS This study showed that TcB nomograms had the same predictive value as TSB nomograms, both of which could be used to identify subsequent significant hyperbilirubinemia. But this result should be interpreted cautiously because some methodological limitations of these included studies were identified in this review.

Prevention of Kernicterus in South Asia: role of neonatal G6PD deficiency and its identification. Indian J Pediatr 2014; 81:599-607.

Abstract
Extreme hyperbilirubinemia (EHB) caused by neonatal glucose-6-phosphate dehydrogenase (G6PD) deficiency is strongly associated with mortality and long-term neurodevelopmental impairment, yet there are limited national strategies to reduce this burden in South Asia. Current known and predicted prevalence of G6PD deficiency in Afghanistan, Bangladesh, Bhutan, India, Nepal, and Pakistan ranges from 3.8 to 15 %, with regional "hot spots" exceeding 22 %. Annually, 3.14 million infants are born at risk for this condition. In 2010, South Asian countries reported 37 million (27 %) of world-wide livebirths ≥ 32 wk gestational-age and G6PD deficiency accounted for > 33 % of the global EHB burden, in contrast to 2.2 % for those born in high-income nations. Traditional national approach includes universal newborn screening in malaria-endemic countries or those with prevalence >3.5 %. However, screening implementation should be best optimized using timely quantitative enzyme assay and identification of at-risk female newborns. Furthermore, economic and social constraints, in context of sub-regional variances, call for flexible problem-solving methods in anticipation of changing community demographics. Thus, incremental and need-based newborn screening programs could be the most optimal approach. A human-centered design (HCD) approach, as an alternate pathway, could build the evidence to translate the complex biology of G6PD deficiency and the biodesign of affordable technologies, allowing facilitation of access to knowledge and services, in order to deliver on a long-term public health mandate. Key steps would encompass the initiation of local inquiry of both quantitative and qualitative data to identify at-risk communities and to prospectively design for local innovative solutions.

Abstract
OBJECTIVE to prospectively validate a previously constructed transcutaneous bilirubin (TcB) nomogram for identifying severe hyperbilirubinemia in healthy Chinese term and late-preterm infants. METHODS this was a multicenter study that included 9,174 healthy term and late-preterm infants in eight hospitals of China. TcB measurements were performed using a JM-103 bilirubinometer. TcB values were plotted on a previously developed TcB nomogram, to identify the predictive ability for subsequent significant hyperbilirubinemia. RESULTS in the present study, 972 neonates (10.6%) developed significant hyperbilirubinemia. The 40(th) percentile of the nomogram could identify all neonates who were at risk of significant hyperbilirubinemia, but with a low positive predictive value (PPV) (18.9%). Of the 453 neonates above the 95(th) percentile, 275 subsequently developed significant hyperbilirubinemia, with a high PPV (60.7%), but with low sensitivity (28.3%). The 75(th) percentile was highly specific (81.9%) and moderately sensitive (79.8%). The area under the curve (AUC) for the TcB nomogram was 0.875. CONCLUSIONS this study validated the previously developed TcB nomogram, which could be used to predict subsequent significant hyperbilirubinemia in healthy Chinese term and late-preterm infants. However, combining TcB nomogram and clinical risk factors could improve the predictive accuracy for severe hyperbilirubinemia, which was not assessed in the study. Further studies are necessary to confirm this combination.

Abstract
BACKGROUND The aim of this study was to establish a model to identify term breast-fed infants who are at risk of developing significant neonatal hyperbilirubinemia. METHODS A prospective study was designed to investigate the effects of birth weight, mode of delivery, cephalohematoma, glucose-6-phosphate dehydrogenase (G6PD) deficiency, predischarge total serum bilirubin, variant uridine 5'diphospho-glucuronosyltransferase 1A1 (UGT1A1) gene, and hepatic solute carrier organic anion transporter 1B1 (SLCO1B1) gene on significant hyperbilirubinemia in term breast-fed neonates. Significant hyperbilirubinemia was defined as a bilirubin level exceeding the hour-specific phototherapy treatment threshold recommended by the American Academy of Pediatrics in 2004. RESULTS Of 240 exclusively breast-fed term neonates, 26 (10.8%) had significant hyperbilirubinemia. The predischarge total serum bilirubin on the third day (odds ratio (OR) = 2.63; 95% confidence interval (CI): 1.87-3.70; P < 0.001) and the variant UGT1A1 gene at nucleotide 211 (OR = 5.00; 95% CI: 1.08-23.03; P < 0.05) were significant risk factors. The area under the receiver operating characteristic (ROC) curve of the predictive probability was 0.964 (95% CI: 0.932-0.984; P < 0.0001). CONCLUSION Combining the total serum bilirubin on the third day and the variant UGT1A1 gene at nucleotide 211 can predict hyperbilirubinemia well in term breast-fed infants.
