Abstract
INTRODUCTION Premature birth and very low birth weight (VLBW) are leading causes of neonatal mortality. Almost all premature infants experience hyperbilirubinaemia. Administering probiotics to breastfeeding mothers may positively affect infant outcomes. This trial aims to investigate whether probiotic supplementation for mothers with VLBW infants affects total serum bilirubin levels and postpartum depression scores (primary outcomes), as well as some other neonatal and maternal outcomes (secondary outcomes). METHODS AND ANALYSIS This is a randomised, double-blind, placebo-controlled superiority trial with two parallel arms. Participants, caregivers and outcome assessors will be blinded. A total of 122 breastfeeding mothers of neonates with a birth weight of 1000-1500 g, along with their infants within 48 hours of birth, will be assigned to either the probiotic or placebo group in a 1:1 ratio through block randomisation, stratified by singleton and twin births. The intervention will involve oral administration of probiotics containing Lactobacillus paracasei 431 and Bifidobacterium lactis BB-12, or an indistinguishable placebo, for 42-45 days. Outcomes will be assessed through daily observations, laboratory assessments and the Edinburgh Postpartum Depression Scale. Adverse events will also be documented. Modified intention-to-treat analyses will be employed for the primary and secondary outcomes, excluding participants lost to follow-up from all postintervention assessments. ETHICS AND DISSEMINATION This study protocol has been approved by the Medical University of Tabriz Ethics Committee (IR.TBZMED.REC.1401.735). Findings will be disseminated through publication in a peer-reviewed journal and presentations at relevant conferences. TRIAL REGISTRATION NUMBER IRCT20100414003706N42.

Association of Breastfeeding and Neonatal Jaundice With Infant Neurodevelopment. Am J Prev Med 2024; 66:698-706. [PMID: 38052381 DOI: 10.1016/j.amepre.2023.11.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Revised: 11/26/2023] [Accepted: 11/27/2023] [Indexed: 12/07/2023]
Abstract
INTRODUCTION Exclusive breastfeeding is advantageous for infant neurodevelopment. Nevertheless, insufficient human milk supply in exclusively breastfed infants may elevate the risk of neonatal jaundice, which can potentially result in neurological harm. Whether mothers should adhere to exclusive breastfeeding in infants with neonatal jaundice remains unclear. METHODS Data comes from the Jiangsu Birth Cohort (JBC), a prospective and longitudinal birth cohort study in China. A total of 2,577 infants born from November 2017 to March 2021 were included in the analysis. Multivariate linear regression models were used to analyze the associations between breastfeeding status, neonatal jaundice, and their interaction with infant neurodevelopment. Analysis was performed in 2022. RESULTS Compared with "exclusive breastfeeding," fine motor scores of infants were lower for "mixed feeding" (βadj, -0.16; 95% CI, -0.29 to -0.03; p=0.016) and "no breastfeeding" (βadj, -0.41; 95% CI, -0.79 to -0.03; p=0.034). Compared with "no neonatal jaundice," infants with "severe neonatal jaundice" had lower scores for cognition (βadj, -0.44; 95% CI, -0.66 to -0.23; p<0.001) and fine motor (βadj, -0.19; 95% CI, -0.35 to -0.03; p=0.024). In infants with severe neonatal jaundice, the termination of exclusive breastfeeding before 6 months was associated with worse cognition (βadj, -0.28; 95% CI, -0.57 to 0.01), while this association was not observed in those without neonatal jaundice (βadj, 0.09; 95% CI, -0.26 to 0.43). CONCLUSIONS Exclusive breastfeeding for the first 6 months is beneficial to the neurodevelopment of infants, especially in those with severe neonatal jaundice.

Abstract
Noninvoluting congenital hemangioma is an extremely rare congenital anomaly in newborn babies and may complicate life-threatening events, including hemorrhage. We present a very rare case of noninvoluting congenital hemangiomas in an Asian and Afghan six-day-old girl that was detected at birth. The noninvoluting congenital hemangiomas were accompanied by hypovolemic shock, anemia, and prolonged jaundice during the first two weeks of life. These diseases were diagnosed by medical history, physical examination, blood analysis, and doppler ultrasonography of the skin lesions. Her hypovolemic shock and hemorrhage were improved after supportive treatment, and she was discharged from the hospital in a good condition. After four weeks of life, the hemangiomas did not regress or progress, suggesting noninvoluting congenital hemangiomas. Hemangioma may complicate severe hemorrhage and shock, as well as there may be an association between congenital hemangioma and prolonged neonatal jaundice.

Abstract
Background Mobile health has enormous potential in healthcare due to the increasing use of mobile phones in low- and middle-income countries; its effective deployment, uptake, and utilization may result in improved health outcomes, including a reduction in neonatal deaths. However, there is a suboptimal uptake of mobile health technologies among healthcare workers in low-resource settings like Nigeria, which are often context-specific. Objective To investigate healthcare workers' perceptions of mobile health technologies in public health facilities in Lagos, Nigeria. Method A qualitative study was conducted, and data were collected through six focus group discussions with 26 healthcare workers (doctors, nurses, and community health extension workers) from three public health facilities in Lagos, Nigeria. The collected data were analyzed using a thematic approach, where themes and subthemes were created. Results Although the participants acknowledged that mobile health enhances patient-provider communication and saves time, they identified altering of healthcare workers' routine practices, information overload, power and network failure, skepticism, lack of trust, and concerns over diagnostic accuracy as potential barriers to its uptake. Conclusion Addressing healthcare workers' perceptions of mobile health technologies may enhance the deployment and uptake of such solutions in Nigeria and similar low-resource settings. Developers and implementers of such can use them to create new or enhance existing mobile health solutions to better meet the needs and requirements of healthcare workers in low- to middle-income health settings, such as Lagos, Nigeria.

Novel hemoperfusion adsorbents based on collagen for efficient bilirubin removal - A thought from yellow skin of patients with hyperbilirubinemia. Int J Biol Macromol 2023; 253:127321.

Abstract
Hemoperfusion is a well-developed method for removing bilirubin from patients with hyperbilirubinemia. The performance of adsorbents is crucial during the process. However, most adsorbents used for bilirubin removal are not suitable for clinical applications, because they either have poor adsorption performance or limited biocompatibility. Patients with hyperbilirubinemia usually have distinctive yellow skin, indicating that collagen, a primary component of the skin, may be an effective material for absorbing bilirubin from the blood. Based on this idea, we designed and synthesized collagen (Col) and collagen-polyethyleneimine (Col-PEI) microspheres and employed them as hemoperfusion adsorbents for bilirubin removal. The microspheres have an efficient adsorption rate, higher bilirubin adsorption capacity, and competitive adsorption of bilirubin in the bilirubin/bovine serum albumin (BSA) solution. The maximum adsorption capacities of Col and Col-PEI microspheres for bilirubin are 150.2 mg/g and 258.4 mg/g, respectively, which are higher than those of most traditional polymer microspheres. Additionally, the microspheres exhibit excellent blood compatibility originating from collagen. Our study provides a new collagen-based strategy for the hemoperfusion treatment of hyperbilirubinemia.

Abstract
BACKGROUND Hyperbilirubinemia is a clinical picture frequently occurring in the neonatal period and may negatively affect the development of infants. AIMS To evaluate term infants with hyperbilirubinemia in terms of both motor development and sensory processing skills and to compare them with their healthy peers without hyperbilirubinemia. STUDY DESIGN A cross-sectional study. SUBJECTS Children born at term, aged 10-18 months, with and without a history of hyperbilirubinemia were included in the study. OUTCOME MEASURES After demographic information was recorded, motor development was evaluated with the Peabody Motor Development Scale-2 and sensory processing skills were evaluated with the Test of Sensory Function in Infant. RESULTS A total of 42 children (mean ± SD age of the children 13.07 ± 1.47 months, 22 with hyperbilirubinemia and 20 without hyperbilirubinemia) were included in the study. A statistically significant difference was found in the gross motor (p = 0.02), fine motor (p = 0.03), and total motor (p = 0.017) development scores of the Peabody Motor Development Scale-2 and in the adaptive motor functions (p = 0.004), visual tactile integration (p < 0.001), and total scores (p = 0.004) of The Test of Sensory Function in Infant in favor of the control group. CONCLUSIONS The motor and sensory processing skills of children born at term with hyperbilirubinemia may be negatively affected. Infants with hyperbilirubinemia should be evaluated from the early period not only in terms of motor but also sensory processing skills and should be supported with appropriate intervention programs.

Abstract
BACKGROUND On the basis of visual-dependent reading method, radiological recognition and assessment of neonatal hyperbilirubinemia (NH) or acute bilirubin encephalopathy (ABE) on conventional magnetic resonance imaging (MRI) sequences are challenging. Prior studies had shown that radiomics was possible to characterize ABE-induced intensity and morphological changes on MRI sequences, and it has emerged as a desirable and promising future in quantitative and objective MRI data extraction. To investigate the utility of radiomics based on T1-weighted sequences for identifying neonatal ABE in patients with hyperbilirubinemia and differentiating between those with NH and the normal controls. METHODS A total of 88 patients with NH were enrolled, including 50 patients with ABE and 38 ABE-negative individuals, and 70 age-matched normal neonates were included as controls. All participants were divided into training and validation cohorts in a 7:3 ratio. Radiomics features extracted from the basal ganglia of T1-weighted sequences on magnetic resonance imaging were evaluated and selected to set up the prediction model using the K-nearest neighbour-based bagging algorithm. A receiver operating characteristic curve was plotted to assess the differentiating performance of the radiomics-based model. RESULTS Four of 744 radiomics features were selected for the diagnostic model of ABE. The radiomics model yielded an area under the curve (AUC) of 0.81 and 0.82 in the training and test cohorts, with accuracy, precision, sensitivity, and specificity of 0.82, 0.80, 0.91, and 0.69 and 0.78, 0.8, 0.8, and 0.75, respectively. Six radiomics features were selected in this model to distinguish those with NH from the normal controls. The AUC for the training cohort was 0.97, with an accuracy of 0.92, a precision of 0.92, a sensitivity of 0.93, and a specificity of 0.90. The performance of the radiomics model was confirmed by testing the test cohort, and the AUC, accuracy, precision, sensitivity, and specificity were 0.97, 0.92, 0.96, 0.89, and 0.95, respectively. CONCLUSIONS The proposed radiomics model based on traditional TI-weighted sequences may be used effectively for identifying ABE and even differentiating patients with NH from the normal controls, which can provide microcosmic information beyond experience-dependent vision and potentially assist in clinical diagnosis and treatment.

Abstract
To determine the effectiveness and safety of prophylactic phototherapy compared with conventional phototherapy for the prevention of neonatal jaundice. We included clinical trials comparing prophylactic phototherapy to conventional phototherapy to prevent jaundice in premature newborns. We searched Embase, MEDLINE, LILACS, Central, and others. The statistical analysis was performed in RevMan (Review Manager 5.3). Outcomes were analyzed according to the type of variable: risk difference (RD) and mean difference (MD). A random effects model was used due to heterogeneity. We reported results in forest plots. Risk of bias was evaluated, and a sensitivity analysis was made. 1127 articles were found, and six studies (2332 patients) were included in the meta-analysis. Five studies evaluated the need for exchange transfusion as the primary outcome RD -0.01, 95% CI [-0.05 to 0.03]. One study evaluated bilirubin encephalopathy RD -0.04, 95% CI [-0.09 to 0.00]. Five studies evaluated the duration of phototherapy, MD 38.47, 95% CI [1.28 to 55.67]. Four studies evaluated levels of bilirubin (MD -1.23, 95% CI [-2.25 to -0.21]. Two studies evaluated mortality, RD 0.01, 95% CI [-0.03 to 0.04]. As a conclusion, compared to conventional phototherapy, prophylactic phototherapy decreases the last measured level of bilirubin, as well as the probability of neurodevelopmental disturbances. However, it increases phototherapy duration.

Abstract
Phototherapy is the most effective non-invasive method of neonatal hyperbilirubinemia treatment. Application of this method can be associated with side effects including changes in the cardiovascular system. During phototherapy, the primary effects in the cardiovascular system include cutaneous vasodilation leading to skin hyperperfusion and subsequent redistribution of blood. The increased blood flow through the skin is associated with increased transepidermal water loss. Further effects include an increase in cerebral blood flow. Redistribution of blood to the cutaneous bed is compensated by hypoperfusion in the splanchnic area (mostly postprandial) and a significant reduction of the renal blood flow. Regarding closure/reopening of the ductus arteriosus, the results suggest that that phototherapy does not affect ductal patency. During phototherapy the cardiac output can be slightly reduced due to a decreased stroke volume, especially in preterm newborns. Systemic blood pressure is decreased and heart rate is elevated in both preterm and term newborns during phototherapy. The heart rate variability is slightly reduced. Symbolic dynamics analysis of the short-term HRV showed that during phototherapy the activity of the ANS regulating the heart rate is shifted towards the dominancy of the sympathetic activity. The responses in the cardiovascular system of premature/mature newborns without other pathology confirm a well physiologically functioning control of this system, even under specific conditions of phototherapy.

Determinants of neonatal jaundice in Ethiopia: a systematic review and meta-analysis. World J Pediatr 2022; 18:725-733. [PMID: 36114364 DOI: 10.1007/s12519-022-00597-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 07/19/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND Neonatal jaundice is a common condition characterized by a yellowish discoloration of the skin, conjunctiva, and sclera caused by elevated serum or plasma bilirubin levels during the newborn period. The condition is usually not dangerous, but it can progress to severe hyperbilirubinemia, which can lead to acute bilirubin encephalopathy and kernicterus, a bilirubin-induced neurological damage. Therefore, this study aimed to assess the pooled prevalence of neonatal jaundice and its determinants in Ethiopia. METHODS Scopus, PubMed, Google Scholar, Embase, and CINAHL databases were searched for studies published between January 1, 2010 and July 30, 2021. A weighted DerSimonian Laird random-effects model was used to estimate the pooled prevalence of neonatal jaundice and its associated factors. The I2 was used to calculate the degree of heterogeneity. The funnel plot and Egger's regression test were used to assess publication bias. RESULTS Totally 697 articles were generated from various databases, and the review included a total of eight articles. The pooled prevalence of neonatal jaundice was 30.96% [95% confidence interval (CI) 16.61%-45.31%)] in Ethiopia. This review showed that prolonged labor [adjusted odd ratio (AOR) = 3.39; 95% CI 2.41-4.77), low birth weight (AOR = 5.12; 95% CI 3.11-8.72), birth asphyxia (AOR = 3.75; 95% CI 2.11-6.66), cephalohematoma (AOR = 7.07; 95% CI 2.72-18.38), ABO incompatibility (AOR = 6.05; 95% CI 2.95-12.42), Rhesus (RH) incompatibility (AOR = 3.77; 95% CI 2.04-6.96), male sex (AOR = 4.53; 95% CI 3.39-6.07), and neonatal sepsis (AOR = 2.47; 95% CI 1.49-4.08) were identified as a determining factor for neonatal jaundice in Ethiopia. CONCLUSIONS In low- and middle-income countries, neonatal jaundice is a significant healthcare burden, accounting for a significant portion of global childhood mortality and morbidity. However, some low-cost, effective, practical, and dependable solutions have been implemented. Prolonged labor, ABO incompatibility, RH incompatibility, birth asphyxia, neonatal sepsis, low birth weight, cephalohematoma, and male sex were identified as risk factors for neonatal jaundice in Ethiopia.

Abstract
OBJECTIVES To assess interlaboratory variability of total serum bilirubin (TSB) results in newborns. Initiated following a clinical incident in which a neonate was transferred to a tertiary hospital for treatment of severe hyperbilirubinemia but on arrival was reclassified into a lower risk category due to a 20% difference in TSB between laboratories. METHODS Fresh residual plasma samples from hospital-born infants were pooled to obtain 11 samples across a range of total bilirubin concentrations. Aliquots were light-protected and measured on 7 commercial platforms at 4 accredited medical laboratories. Data from The Royal College of Pathologists of Australasia Quality Assurance Programs' (RCPAQAP) Neonatal Bilirubin program was analysed. RESULTS Twenty-four to 30% difference in results for individual samples, largely due to calibration differences between assays. When interpreted according to guidelines, results from different platforms would have led to different clinical interventions in some cases. RCPAQAP results showed significant within-method bias but were not shown to be commutable with patient samples. CONCLUSIONS There are clinically significant method-dependent differences in TSB results from neonatal samples, consistent with our clinical incident. The differences are largely due to lack of standardisation of calibrator values. This has implications for healthcare resource use and possibly for the neurodevelopment of infants. Intervention is needed at a number of levels, including clinical reporting of incidents arising from discordant results, commitment by manufacturers to ensure metrological traceability of methods with sufficiently low uncertainty in the final measurements, and availability of commutable quality assurance material to monitor assay performance, especially at the clinical decision points for neonatal jaundice.

Abstract
BACKGROUND Differentiating acute bilirubin encephalopathy (ABE) from non-ABE in neonates with hyperbilirubinemia (HB) from routine magnetic resonance imaging (MRI) is extremely challenging since both conditions demonstrate similar T1 hyperintensities. To this end, we investigated whether the integration of multimodal MRI from routine clinical scans with deep-learning approaches could improve diagnostic performance. METHODS A total of 75 neonates with ABE and 75 neonates with HB (non-ABE) were included in the study. Each patient had three types of multimodal images taken, i.e., a T1-weighted image (T1WI), a T2-weighted image (T2WI), and an apparent diffusion coefficient (ADC) map. The three types of MRI contrasts and their combination were fed into two deep convolutional neural networks (CNNs), i.e., ResNet18 and DenseNet201. The performance of CNNs was compared with a traditional statistical method named logistic regression. RESULTS We demonstrated that diagnostic methods with the multimodal data were better than any of the single-modal data. Both CNN models outperformed the logistic regression method. The best performance was achieved by DenseNet201 with the combination of three modalities of T1WI, T2WI, and ADC, with an accuracy of 0.929 ± 0.042 and an area under the curve (AUC) of 0.991 ± 0.007. CONCLUSIONS Our study demonstrated that CNN models with multimodal MRI significantly improve the accuracy of diagnosing ABE. IMPACT We proposed an efficient strategy of detecting ABE in neonates based on multimodal MRI with deep learning, which achieved an accuracy of 0.929 ± 0.042 and an AUC of 0.991 ± 0.007. We demonstrated the advantage of integrating multimodal MRI in detecting ABE in neonates with HB, using deep-learning models. Our strategy of diagnosing ABE using deep-learning techniques with multimodal MRI from routine clinical scans is potentially applicable to clinical practice.

Abstract
Neonatal jaundice is one of the most common clinical conditions affecting newborns. For most newborns, jaundice is harmless, however, a proportion of newborns develops severe neonatal jaundice requiring therapeutic interventions, accentuating the need to have reliable and accurate screening tools for timely recognition across different health settings. The gold standard method in diagnosing jaundice involves a blood test and requires specialized hospital-based laboratory instruments. Despite technological advancements in point-of-care laboratory medicine, there is limited accessibility of the specialized devices and sample stability in geographically remote areas. Lack of suitable testing options leads to delays in timely diagnosis and treatment of clinically significant jaundice in developed and developing countries alike. There has been an ever-increasing need for a low-cost, simple to use screening technology to improve timely diagnosis and management of neonatal jaundice. Consequently, several point-of-care (POC) devices have been developed to address this concern. This paper aims to review the literature, focusing on emerging technologies in the screening and diagnosing of neonatal jaundice. We report on the challenges associated with the existing screening tools, followed by an overview of emerging sensors currently in pre-clinical development and the emerging POC devices in clinical trials to advance the screening of neonatal jaundice. The benefits offered by emerging POC devices include their ease of use, low cost, and the accessibility of rapid response test results. However, further clinical trials are required to overcome the current limitations of the emerging POC's before their implementation in clinical settings. Hence, the need for a simple to use, low-cost POC jaundice detection technology for newborns remains an unsolved challenge globally.

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
OBJECTIVE The cephalocaudal progression in neonatal jaundice is a well-known phenomenon. Since transcutaneous bilirubin measurements (TcB) are increasingly applied, for which different body site can be used, we aimed to quantify the cephalocaudal progression of neonatal jaundice through TcB and to assess the influence of gestational age, postnatal age and the degree of hyperbilirubinemia on this cephalocaudal progression. STUDY DESIGN In jaundiced neonates ≥32 weeks of gestational age, TcB was measured on 5 sites: forehead, sternum, hipbone, proximal tibia and foot, during the first two weeks of life. RESULTS 58 neonates were included. Mean ratios of TcB on the 5 sites compared to the forehead were: sternum 1,03 (SD 0,14), hipbone 0,80 (SD 0,16), proximal tibia 0,63 (SD 0,14) and foot 0,44 (SD 0,15). Gestational age, postnatal age nor the degree of hyperbilirubinemia were associated with the cephalocaudal progression (ANOVA p > 0,05). CONCLUSION The cephalocaudal progression of neonatal jaundice is evident, with caudal levels of TcB being less than half of cephalic measurements. This implicates that TcB measurements caudal from the sternum are less reliable, and should be avoided. The degree of cephalocaudal progression is not associated with gestational or postnatal age, nor with height of bilirubin levels.

Abstract
Glucose-6-phosphate dehydrogenase (G6PD) deficiency, the most common enzymopathy worldwide, is an insufficient amount of the G6PD enzyme, which is vital to the protection of the erythrocyte. Deficient enzyme levels lead to oxidative damage, hemolysis, and resultant severe hyperbilirubinemia. If not promptly recognized and treated, G6PD deficiency can potentially lead to bilirubin-induced neurologic dysfunction, acute bilirubin encephalopathy, and kernicterus. Glucose-6-phosphate dehydrogenase deficiency is one of the three most common causes for pathologic hyperbilirubinemia. A change in migration patterns and intercultural marriages have created an increased incidence of G6PD deficiency in the United States. Currently, there is no universally mandated metabolic screening or clinical risk assessment tool for G6PD deficiency in the United States. Mandatory universal screening for G6PD deficiency, which includes surveillance and hospital-based risk assessment tools, can identify the at-risk infant and foster early identification, diagnosis, and treatment to eliminate neurotoxicity.

Abstract
OBJECTIVE To assess the accuracy of umbilical cord bilirubin values to predict jaundice in the first 48h of life and neonatal infection. METHOD Newborn infants treated at a regional well-baby nursery born at ≥36 weeks of gestation were included in this retrospective cohort study. All infants born in a 3-year period from mothers with O blood type and/or Rh-negative were included and had the umbilical cord bilirubin levels measured. Hyperbilirubinemia in the first 48h was defined as bilirubin levels above the phototherapy threshold. Neonatal infection was defined as any antibiotic treatment before discharge. RESULTS A total of 1360 newborn infants were included. Two hundred and three (14.9%) newborn infants developed hyperbilirubinemia in the first 48h of life. Hyperbilirubinemic infants had smaller birth weight, higher levels of umbilical cord bilirubin, a higher rate of infection and were more often direct antiglobulin test positive. Umbilical cord bilirubin had a sensitivity of 76.85% and a specificity of 69.58% in detecting hyperbilirubinemia in the first 48h, with the cut-off value at 34μmol/L. The area under the receiver operating characteristic curve was 0.80 (95% CI: 0.78-0.82). Umbilical cord bilirubin had a sensitivity of 27.03% and specificity of 91.31% in detecting perinatal infection. The area under the receiver operating characteristic (ROC) curve was 0.59 (95% CI: 0.57-0.63). CONCLUSIONS A positive correlation was found between umbilical cord bilirubin and hyperbilirubinemia in the first 48h of life. Umbilical cord bilirubin is a poor marker for predicting neonatal infection.

Abstract
Background Neonatal hyperbilirubinemia is a common clinical condition that requires medical attention in newborns, which may develop into acute bilirubin encephalopathy with a significant risk of long-term neurological deficits. The current clinical challenge lies in the separation of acute bilirubin encephalopathy and non-acute bilirubin encephalopathy neonates both with hyperbilirubinemia condition since both of them demonstrated similar T1 hyperintensity and lead to difficulties in clinical diagnosis based on the conventional radiological reading. This study aims to investigate the utility of T1-weighted MRI images for differentiating acute bilirubin encephalopathy and non-acute bilirubin encephalopathy neonates with hyperbilirubinemia. Methods 3 diagnostic approaches, including a visual inspection, a semi-quantitative method based on normalized the T1-weighted intensities of the globus pallidus and subthalamic nuclei, and a deep learning method with ResNet18 framework were applied to classify 47 acute bilirubin encephalopathy neonates and 32 non-acute bilirubin encephalopathy neonates with hyperbilirubinemia based on T1-weighted images. Chi-squared test and t-test were used to test the significant difference of clinical features between the 2 groups. Results The visual inspection got a poor diagnostic accuracy of 53.58 ± 5.71% indicating the difficulty of the challenge in real clinical practice. However, the semi-quantitative approach and ResNet18 achieved a classification accuracy of 62.11 ± 8.03% and 72.15%, respectively, which outperformed visual inspection significantly. Conclusion Our study indicates that it is not sufficient to only use T1-weighted MRI images to detect neonates with acute bilirubin encephalopathy. Other more MRI multimodal images combined with T1-weighted MRI images are expected to use to improve the accuracy in future work. However, this study demonstrates that the semi-quantitative measurement based on T1-weighted MRI images is a simple and compromised way to discriminate acute bilirubin encephalopathy and non-acute bilirubin encephalopathy neonates with hyperbilirubinemia, which may be helpful in improving the current manual diagnosis.

Association between type of phototherapy management and hospital and patient-related outcomes in neonates with non-haemolytic jaundice at an Australian community hospital. J Paediatr Child Health 2021; 57:702-709. [PMID: 33369815 DOI: 10.1111/jpc.15317] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 11/30/2020] [Accepted: 12/01/2020] [Indexed: 11/30/2022]
Abstract
AIM To evaluate the associations between type of light-emitting diode phototherapy intervention and hospital and patient related outcomes in term neonates with non-haemolytic jaundice. METHODS A retrospective observational study in a community hospital within a disadvantaged area in Australia was conducted. Data was extracted from hospital systems and medical records regarding the use of three types of phototherapy surface-area exposure for term neonates ≤28 days with non-haemolytic neonatal jaundice. Associations between type of phototherapy management and length of stay (LOS), rate of serum bilirubin (SBR) decline and duration of phototherapy were estimated using the general linear mixed model or linear regression. RESULTS Of 102 neonates diagnosed with non-haemolytic jaundice between 1 June 2016 and 31 August 2017, 82 were included in final analyses. Neonates treated for jaundice during their first (birth) admission had a median LOS of 118 h for single-sided and 125 h for maximal double-sided phototherapy. Differences by phototherapy type were not statistically significant (P = 0.06). SBR rate of decline increased as surface-area of phototherapy increased (P < 0.001) with the fastest decline seen in maximal double-sided phototherapy. Estimated duration of phototherapy did not vary by phototherapy type but did vary by age at initiation of phototherapy (P = 0.006), with 16 fewer hours of phototherapy if commenced at ≥72 to <96 h versus ≥24 to 48 h of age (difference -16.4 h, 95% confidence interval -29.1 to -3.7 h). CONCLUSIONS LOS and phototherapy duration were not associated with phototherapy type. Older neonates with neonatal jaundice required shorter phototherapy duration. Double-sided phototherapy was associated with faster reduction in SBR.

Abstract
Based on the green chemistry approach, highly fluorescent and novel carbon dots (C. dots) were synthesized from naturally available and cost effective sunflower seeds. The obtained C. dots showed a fluorescence quantum yield (Q.Y) of 9.5% with high water dispersibility and photostability. The obtained C. dots were employed for the detection of picric acid (PA) and bilirubin. A good linear relationship in the range of 20-60 nM was obtained for PA with a limit of detection (LOD) as low as 3.86 nM. C. dots were successfully incorporated in the agarose matrix which enabled them to be employed as a solid platform for the in situ detection of PA. The fluorescence of C. dots was selectively quenched by bilirubin compared to other biomolecules with a LOD of 2.03 μM. Use of C. dots as potential candidate for bilirubin detection was verified by real sample analysis. Further, the separation of C. dots was performed using column chromatography and the optical properties of the two different fractions obtained were studied. The blue fraction of C. dots was found to exhibit a higher fluorescence Q.Y and excitation independent emission, with an improved detection of PA and bilirubin.

Abstract
Jaundice occurs as a symptom of various diseases, such as hepatitis, the liver cancer, gallbladder or pancreas. Therefore, clinical measurement with special equipment is a common method that is used to identify the total serum bilirubin level in patients. Fully automated multi-class recognition of jaundice combines two key issues: (1) the critical difficulties in multi-class recognition of jaundice approaches contrasting with the binary class and (2) the subtle difficulties in multi-class recognition of jaundice represent extensive individuals variability of high-resolution photos of subjects, huge coherency between healthy controls and occult jaundice, as well as broadly inhomogeneous color distribution. We introduce a novel approach for multi-class recognition of jaundice to detect occult jaundice, obvious jaundice and healthy controls. First, region annotation network is developed and trained to propose eye candidates. Subsequently, an efficient jaundice recognizer is proposed to learn similarities, context, localization features and globalization characteristics on photos of subjects. Finally, both networks are unified by using shared convolutional layer. Evaluation of the structured model in a comparative study resulted in a significant performance boost (categorical accuracy for mean 91.38%) over the independent human observer. Our work was exceeded against the state-of-the-art convolutional neural network (96.85% and 90.06% for training and validation subset, respectively) and showed a remarkable categorical result for mean 95.33% on testing subset. The proposed network makes a performance better than physicians. This work demonstrates the strength of our proposal to help bringing an efficient tool for multi-class recognition of jaundice into clinical practice.

Abstract
The heme oxygenase (HO) system involves three isoforms of this enzyme, HO-1, HO-2, and HO-3. The three of them display the same catalytic activity, oxidating the heme group to produce biliverdin, ferrous iron, and carbon monoxide (CO). HO-1 is the isoform most widely studied in proinflammatory diseases because treatments that overexpress this enzyme promote the generation of anti-inflammatory products. However, neonatal jaundice (hyperbilirubinemia) derived from HO overexpression led to the development of inhibitors, such as those based on metaloproto- and meso-porphyrins inhibitors with competitive activity. Further, non-competitive inhibitors have also been identified, such as synthetic and natural imidazole-dioxolane-based, small synthetic molecules, inhibitors of the enzyme regulation pathway, and genetic engineering using iRNA or CRISPR cas9. Despite most of the applications of the HO inhibitors being related to metabolic diseases, the beneficial effects of these molecules in immune-mediated diseases have also emerged. Different medical implications, including cancer, Alzheimer´s disease, and infections, are discussed in this article and as to how the selective inhibition of HO isoforms may contribute to the treatment of these ailments.

Regulation of Intestinal UDP-Glucuronosyltransferase 1A1 by the Farnesoid X Receptor Agonist Obeticholic Acid Is Controlled by Constitutive Androstane Receptor through Intestinal Maturation. Drug Metab Dispos 2020; 49:12-19. [PMID: 33154041 DOI: 10.1124/dmd.120.000240] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 10/14/2020] [Indexed: 12/28/2022] Open
Abstract
UDP-glucuronosyltransferase (UGT) 1A1 is the only transferase capable of conjugating serum bilirubin. However, temporal delay in the development of the UGT1A1 gene leads to an accumulation of serum bilirubin in newborn children. Neonatal humanized UGT1 (hUGT1) mice, which accumulate severe levels of total serum bilirubin (TSB), were treated by oral gavage with obeticholic acid (OCA), a potent FXR agonist. OCA treatment led to dramatic reduction in TSB levels. Analysis of UGT1A1 expression confirmed that OCA induced intestinal and not hepatic UGT1A1. Interestingly, Cyp2b10, a target gene of the nuclear receptor CAR, was also induced by OCA in intestinal tissue. In neonatal hUGT1/Car -/- mice, OCA was unable to induce CYP2B10 and UGT1A1, confirming that CAR and not FXR is involved in the induction of intestinal UGT1A1. However, OCA did induce FXR target genes, such as Shp, in both intestines and liver with induction of Fgf15 in intestinal tissue. Circulating FGF15 activates hepatic FXR and, together with hepatic Shp, blocks Cyp7a1 and Cyp7b1 gene expression, key enzymes in bile acid metabolism. Importantly, the administration of OCA in neonatal hUGT1 mice accelerates intestinal epithelial cell maturation, which directly impacts on induction of the UGT1A1 gene and the reduction in TSB levels. Accelerated intestinal maturation is directly controlled by CAR, since induction of enterocyte marker genes sucrase-isomaltase, alkaline phosphatase 3, and keratin 20 by OCA does not occur in hUGT1/Car -/- mice. Thus, new findings link an important role for CAR in intestinal UGT1A1 induction and its role in the intestinal maturation pathway. SIGNIFICANCE STATEMENT: Obeticholic acid (OCA) activates FXR target genes in both liver and intestinal tissues while inducing intestinal UGT1A1, which leads to the elimination of serum bilirubin in humanized UGT1 mice. However, the induction of intestinal UGT1A1 and the elimination of bilirubin by OCA is driven entirely by activation of intestinal CAR and not FXR. The elimination of serum bilirubin is based on a CAR-dependent mechanism that facilitates the acceleration of intestinal epithelium cell differentiation, an event that underlies the induction of intestinal UGT1A1.

Abstract
Objective This study determined the predictors of maternal knowledge and health-seeking behavior for neonatal jaundice in rural Kumbotso, northern Nigeria. Study design Cross-sectional survey. Method A total of 361 mothers were interviewed using structured questionnaires. Knowledge scores and care-seeking practices were determined. Adjusted odds ratios were generated from logistic regression models. Results The proportion of respondents with good, fair and poor knowledge of neonatal jaundice were (46.0%, n = 166), (24.1%, n = 87) and (30.0%, n = 108), respectively. Of the 117 mothers with a jaundiced child, (67.5%, n = 79) and (20.5%, n = 24) received treatment from health facilities and traditional healers, respectively, whereas (12.0%, n = 14) resorted to home remedies. Maternal education Adjusted Odds Ratio (AOR) = 2.39; 95% Confidence Interval (CI): 1.16–4.91) (secondary school versus no formal), source of information on neonatal jaundice (AOR = 11.3; 95%CI: 5.84–21.93) (health worker versus ‘others’), recent delivery in a health facility (AOR = 1.83; 95%CI: 1.06–3.14) and having a previously jaundiced child (AOR = 5.06; 95%CI: 2.76–9.27) predicted knowledge. Preference for health facility treatment was predicted by a previously jaundiced child (AOR = 10.04; 95%CI: 5.73–17.60), antenatal care (AOR = 2.97; 95%CI: 1.43–6.15) (≥4 versus 0 visits), source of information on neonatal jaundice (AOR = 2.33; 95%CI: 1.30–4.17) (health worker versus ‘others’), and maternal ethnicity (AOR = 0.36; 95%CI: 0.14–0.96) (Hausa-Fulani versus ‘others’). Conclusion Maternal knowledge of neonatal jaundice was sub-optimal. Being educated, health facility delivery, having had a jaundiced child, and receiving information from health workers predicted good knowledge. Having a previously jaundiced child, antenatal care, obtaining information from health workers and maternal ethnicity predicted preference for health facility treatment. Policies and programs should be strengthened to focus on prevention, early detection and prompt management of neonatal jaundice.

Abstract
Background Hyperbilirubinemia affects many newborn infants and, if not treated appropriately, can lead to irreversible brain injury. Objective This study aims to develop predictive models of follow-up total serum bilirubin measurement and to compare their accuracy with that of clinician predictions. Methods Subjects were patients born between June 2015 and June 2019 at 4 hospitals in Massachusetts. The prediction target was a follow-up total serum bilirubin measurement obtained <72 hours after a previous measurement. Birth before versus after February 2019 was used to generate a training set (27,428 target measurements) and a held-out test set (3320 measurements), respectively. Multiple supervised learning models were trained. To further assess model performance, predictions on the held-out test set were also compared with corresponding predictions from clinicians. Results The best predictive accuracy on the held-out test set was obtained with the multilayer perceptron (ie, neural network, mean absolute error [MAE] 1.05 mg/dL) and Xgboost (MAE 1.04 mg/dL) models. A limited number of predictors were sufficient for constructing models with the best performance and avoiding overfitting: current bilirubin measurement, last rate of rise, proportion of time under phototherapy, time to next measurement, gestational age at birth, current age, and fractional weight change from birth. Clinicians made a total of 210 prospective predictions. The neural network model accuracy on this subset of predictions had an MAE of 1.06 mg/dL compared with clinician predictions with an MAE of 1.38 mg/dL (P<.0001). In babies born at 35 weeks of gestation or later, this approach was also applied to predict the binary outcome of subsequently exceeding consensus guidelines for phototherapy initiation and achieved an area under the receiver operator characteristic curve of 0.94 (95% CI 0.91 to 0.97). Conclusions This study developed predictive models for neonatal follow-up total serum bilirubin measurements that outperform clinicians. This may be the first report of models that predict specific bilirubin values, are not limited to near-term patients without risk factors, and take into account the effect of phototherapy.

Abstract
BACKGROUND Neonatal hyperbilirubinemia is a common condition that frequently requires treatment with phototherapy and less commonly by exchange transfusion, especially in preterm infants. It is important to identify and monitor infants at risk of severe unconjugated hyperbilirubinemia early in the postnatal period to instigate appropriate management plans. AIMS To evaluate transcutaneous bilirubinometry (TCB) as a screening tool at 24 and 48 h of age to predict the need for phototherapy during hospital stay in preterm infants. STUDY DESIGN A single centre prospective cohort study in a level III perinatal centre. SUBJECTS Preterm infants (23+0 to 36+6 weeks of gestation) were eligible for enrolment. OUTCOME MEASURES Primary outcome was to assess the predictive value of TCB at 24 and 48 h of age for the need of phototherapy during hospital stay. RESULTS A total of 338 preterm infants were enrolled. The majority of infants (98.1%) born below 32 weeks of gestation required phototherapy. For infants born at >31 + 6 weeks of gestation, TCB at 24 h of age ≥81 μmol/l had sensitivity 83%, specificity 56%, positive predictive value (PPV) 54.7% and negative predictive value (NPV) 84%. TCB at 48 h of age ≥145 μmol/l had sensitivity 65%, specificity 62%, PPV 24% and NPV 90%. CONCLUSION TCB performed poorly at 24 and 48 h of age as a predictor of phototherapy during hospital stay in preterm infants. The negative predictive value of the test at 48 h of age might be helpful for infants born after 31 + 6 weeks of gestation.

Abstract
BACKGROUND Neonatal jaundice is associated with a significant risk of neonatal morbidity and mortality. It is a major cause of hospital neonatal intensive care unit admission and readmissions during the neonatal period. Hence, the study aimed to identify the determinant factors of neonatal jaundice among neonates admitted at five referral hospitals in Amhara region, Northern Ethiopia. METHOD A hospital-based unmatched case-control study design was employed, on 447 neonates (149 cases and 298 controls) at referral hospitals in Amhara region, Northern Ethiopia, from 1 March to 30 July 2019. Consecutive sampling method was used to select both the cases and controls. The collected data were entered into Epi data V.4.2 and then exported into SPSS window V.24 for analysis. Bivariable and multivariable analysis were carried out by using binary logistic regression. A p value of <0.05 was considered as significant difference between cases and controls for the exposure variable of interest. RESULTS The median (±IQR) age of neonate at the time of admission and gestational age were 3±2 days and 38 (±3) weeks, respectively. Prolonged duration of labour (adjusted OR (AOR)=2.45, 95% CI 1.34 to 4.47), being male sex (AOR=3.54, 95% CI 1.99 to 6.29), low birth weight (AOR=5.06, 95% CI 2.61 to 9.82), birth asphyxia (AOR=2.88, 95% CI 1.38 to 5.99), sepsis (AOR=2.49, 95% CI 1.22 to 5.11) and hypothermia (AOR=2.88, 95% CI 2.63 to 14.02) were the determinant factors for neonatal jaundice. CONCLUSIONS Prolonged duration of labour, hypothermia, sepsis, birth asphyxia, low birth weight and sex of neonate were independent determinants of neonatal jaundice. Early recognition and management of identified modifiable determinants are the recommended interventions.

Intravenous Immunoglobulins as Adjunct Treatment to Phototherapy in Isoimmune Hemolytic Disease of the Newborn: A Retrospective Case-Control Study. J Clin Med Res 2019; 11:760-763. [PMID: 31803318 PMCID: PMC6879023 DOI: 10.14740/jocmr4003] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2019] [Accepted: 09/30/2019] [Indexed: 11/11/2022] Open
Abstract
Background Isoimmune hemolytic disease is a major cause of neonatal severe indirect hyperbilirubinemia that requires phototherapy or exchange transfusion which is an invasive procedure to avoid brain injury. Administration of intravenous immunoglobulin (IVIG) is used as an adjunct treatment to phototherapy in order to decrease the rate of exchange transfusion. Methods This retrospective case-control study aimed to describe the safety and efficacy of IVIG therapy in newborns with isoimmune hemolytic disease and to compare their clinical outcomes to those of a control group who were treated only with phototherapy. Criteria for IVIG treatment were variable; when phototherapy threshold was reached or when exchange transfusion level was approached, using either indication is based on the attending discretion. Results Ninety-four infants were included in the IVIG group, compared to 108 infants in the control group. Most of the included infants were term infants and most common cause was ABO incompatibility. There were no side effects documented in all the included infants. The IVIG group had more severe hemolysis with average highest bilirubin of 14.6 ± 3.7 mg/dL in the IVIG group versus 12.6 ± 3 in the control group (P = 0.0001). Complication of hemolysis was seen more in the IVIG group with higher rate of rebound hyperbilirubinemia, blood transfusion and exchange transfusion. Conclusions IVIG use as an adjunct treatment to phototherapy in isoimmune hemolytic disease of the newborns is safe. The favorable results of the phototherapy only group were supportive of using selective criteria for administration of IVIG in neonates with isoimmune hemolytic disease.

Front Neurol 2019; 10:1018. [PMID: 31632332 PMCID: PMC6779823 DOI: 10.3389/fneur.2019.01018] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Accepted: 09/09/2019] [Indexed: 01/14/2023] Open
Abstract
Background: The use of magnetic resonance imaging (MRI) in diagnosis of neonatal acute bilirubin encephalopathy (ABE) in newborns has been limited by its difficulty in differentiating confounding image contrast changes associated with normal myelination. This study aims to demonstrate the feasibility of building a machine learning prediction model based on radiomics features derived from MRI to better characterize and distinguish ABE from normal myelination. Methods: In this retrospective study, we included 32 neonates with clinically confirmed ABE and 29 age-matched controls with normal myelination. Radiomics features were extracted from the manually segmented region of interest (ROI) on T1-weighted spin echo images, followed by the feature selection using two-sample independent t-test, least absolute shrinkage and selection operator (Lasso) regression, and Pearson's correlation matrix. Additional feature quantifying the relative mean intensity of ROI was defined and calculated. A prediction model based on the selected features was built to classify ABE and normal myelination using multiple machine learning classifiers and a leave-one-out cross-validation scheme. Receiver operating characteristics (ROC) analysis was used to evaluate the prediction performance with the area under the curve (AUC) and feature importance ranked based on the Fisher score. Results: Among 1319 radiomics features, one radiologist-defined intensity-based feature and 12 texture features were selected as the most discriminative features. Based on these features, decision trees had the best classification performance with the largest AUC of 0.946, followed by support vector machine (SVM), tree-bagger, logistic regression, Naïve Bayes, discriminant analysis, and k-nearest neighborhood (KNN), which have an AUC of 0.931, 0.925, 0.905, 0.891, 0.883, and 0.817, respectively. The relative mean intensity outperformed other 12 texture features in differentiating ABE from controls. Conclusions: The results from this study demonstrated a new strategy of characterizing ABE-induced intensity and morphological changes in MRI, which are difficult to be recognized, interpreted, or quantified by the routine experience and visual-based reading strategy. With more quantitative and objective measurements, the reported machine learning assisted radiomics features-based approach can improve the diagnosis and support clinical decision-making.

Abstract
With the improvement in neonatal care in last two decades, the survival of very low birth weight (VLBW), extremely low birth weight (ELBW), fetus diagnosed with malformations, and congenital heart disease and severe birth asphyxia has increased significantly. These infants when admitted to the neonatal intensive care unit (NICU) need numerous interventions depending upon the severity of sickness and postnatal course like need of mechanical ventilation (MV) or noninvasive ventilation, surfactant administration, placement of central lines, total parenteral nutrition, and numerous medications. The duration of NICU and hospital stay of these high-risk infants varies from few days to few weeks to few months. Long stay in the hospital leads to high hospital bills and increase the cost of neonatal care substantially. The cost of NICU stay varies from 90 USD to 1250-2500 USD per day as per various studies, depending upon the level of care and sickness of the admitted infants. In developed countries, the burden of NICU cost is often taken care by the government or insurance companies but in many developing countries the parents bear the substantial cost of NICU admission of their infants. There are many interventions which when implemented in the NICU will lead to reduction of the cost and will make the NICU cost effective. In this review, we cover various interventions mostly from our own published work which have shown to reduce the NICU cost and make it more cost effective with equivalent and better neonatal outcomes, especially in developing countries like ours.

Spectrophotometry assays to determine G6PD activity from Trinity Biotech and Pointe Scientific G6PD show good correlation. BMC Res Notes 2018; 11:855. [PMID: 30514365 PMCID: PMC6278131 DOI: 10.1186/s13104-018-3964-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2018] [Accepted: 11/29/2018] [Indexed: 01/12/2023] Open
Abstract
OBJECTIVES Spectrophotometry kits from Pointe Scientific (PS; USA) were compared to kits from Trinity Biotech (Trinity; Ireland) in 50 venous blood samples from purposively selected individuals in Bangladesh. Repeatability and inter-assay variability were assessed by Students t-test, Bland-Altman plot and Pearson correlation coefficient (r). The median glucose-6-phosphate dehydrogenase (G6PD) activity of all G6PD normal participants was calculated per assay and defined as 100% activity. Performance was calculated considering 30% and 70% cut off activities and Trinity as reference. RESULTS The intra-assay correlation of Trinity (r = 0.9841, p < 0.001) and PS (r = 0.9833, p < 0.001) did not differ significantly (p = 0.904). Both assays were closely correlated (r = 0.9799, p < 0.001), with a mean difference of 0.1 U/gHb (95% limit of agreement: - 1.32 to 1.57). At 30% cut off PS had a sensitivity of 100% (95% confidence interval (95 CI) 59.0-100.0) and specificity of 100% (95% CI 91.8 to 100.0), at 70% cut-off of 100% (95% CI 79.4-100.0) and 97.1% (95% CI 84.7-99.9) respectively. The G6PD assay from PS is a reliable alternative to the assay from Trinity.

Abstract
BACKGROUND Glucose-6-Phosphate dehydrogenase (G6PD) deficiency is the most common enzymopathy worldwide, no reliable bedside diagnostic tests to quantify G6PD activity exist. This study evaluated two novel quantitative G6PD diagnostics. METHODS Participants with known G6PD activity were enrolled in Bangladesh. G6PD activity was measured by spectrophotometry, Biosensor (BS; AccessBio/CareStart, USA) and STANDARD G6PD (SG; SDBiosensor, ROK). G6PD activity was measured repeatedly in a subset of samples stored at room temperature and 4°C. RESULTS 158 participants were enrolled, 152 samples tested by BS, 108 samples by SG and 102 samples were tested by all three methods. In comparison to spectrophotometry BS had sensitivity and specificity of 72% (95%CI: 53-86) and 100% (95%CI: 97-100) at 30% cut off respectively, while SG had a sensitivity of 100% (95%CI: 88-100) and specificity of 97% (95%CI: 91-99) at the same cut off. The sensitivity and specificity at 70% cut off activity were 71% (95%CI: 59-82) and 98% (95%CI, 92-100) respectively for BS and 89% (95%CI: 77-96) and 93% (95%CI: 83-98) respectively for SG. When an optimal cut-off was applied the sensitivity of the BS at 70 cut off rose to 91% [95%CI: 80-96] and specificity to 82% [95%CI: 83-89]; a diagnostic accuracy comparable to that of the SG (p = 0.879). G6PD activity dropped significantly (-0.31U/gHb, 95%CI: -0.61 to -0.01, p = 0.022) within 24 hours in samples stored at room temperature, but did not fall below 90% of baseline activity until day 13 (-0.87U/gHb, 95%CI: (-1.11 to -0.62), p<0.001). CONCLUSION BS and SG are the first quantitative diagnostics to measure G6PD activity reliably at the bedside and represent suitable alternatives to spectrophotometry in resource poor settings. If samples are stored at 4°C, G6PD activity can be measured reliably for at least 7 days after sample collection.

Abstract
Neonatal jaundice often occurs in the first week after birth. Early detection of neonatal jaundice can prevent kernicterus as a complication of high levels of bilirubin in neonates. Visual assessment is one of the examinations introduced by Kramer to assess the presence of neonatal jaundice. The purpose of this study was to determine the sensitivity, specificity, and accuracy of Kramer's visual assessment in the examination of neonatal jaundice. This study used cross-sectional design to examine 102 infants, with the sample selected by the convenience sampling method. A 2 × 2 table diagnostic test was employed in this study to analyze the data. The results of this study showed that visual assessment of neonatal jaundice obtained a sensitivity value of 76.92%, a specificity value of 89.47%, and an accuracy value of 86.27%. This research can contribute to the development of other non-invasive methods for assessing neonatal jaundice, and thereby contribute to a decrease in neonatal morbidity.

Abstract
Herein, we report the preparation of graphene oxide dots (GO dots) by fine-tuning the carbonization degree of citric acid. The structure of GO dots was characterized by absorption spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, as well as high-resolution scanning electron microscopy and transmission electron microscopy analyses. The typical particle size of the GO dots was 42 nm. The fluorescent characteristics of the GO dots were analyzed by fluorescence spectroscopy. Once excited at 360 nm, the GO dots were fluorescent in the range of 450-550 nm, which was dependent on the excitation wavelength. Further, GO dots were effectively utilized for multifarious applications such as photoinduced electron transfer and detection of explosives and biomolecules. The emission property of GO dots was competently quenched by viologens, picric acid (PA), and bilirubin (BR). The mechanism of quenching by viologens and explosives/biomolecules was found to be due to photoinduced electron transfer and the internal filter effect, respectively. Intriguingly, the detection minimum of PA is in the nanomolar level. Toward commercialization, the economic test strips have also been introduced for the identification of PA. Furthermore, the GO dots have been applied as an efficient luminescent bioprobe for a selective and perceptive finding of BR.

Abstract
Neonatal hyperbilirubinemia and the onset of bilirubin encephalopathy and kernicterus result in part from delayed expression of UDP-glucuronosyltransferase 1A1 (UGT1A1) and the ability to metabolize bilirubin. It is generally believed that acute neonatal forms of hyperbilirubinemia develop due to an inability of hepatic UGT1A1 to metabolize efficiently bilirubin for clearance through the hepatobiliary tract. Newly developed mouse models designed to study bilirubin metabolism have led to new insight into the role of the intestinal tract in controlling neonatal hyperbilirubinemia. Humanization of mice with the UGT1 locus (hUGT1 mice) and the UGT1A1 gene provide a unique tool to study the onset of hyperbilirubinemia since the human UGT1A1 gene is developmentally regulated during the neonatal period in hUGT1 mice. A new mechanism outlying developmental expression of intestinal UGT1A1 is presented and its implications in the control of neonatal hyperbilirubinemia discussed. New findings linking breast milk protection against necrotizing enterocolitis and intestinal control of UGT1A1 may help explain the contribution of breast milk toward the development of neonatal hyperbilirubinemia. Our findings outline a new model that includes an active intestinal ROS /IκB kinase/nuclear receptor corepressor 1 loop that can be applied to an understanding of breast milk-induced jaundice.

Abstract
Biotransformation is an enzyme-catalyzed process in which the body converts endogenous compounds, xenobiotics and toxic substances into harmless or easily excreted metabolites. The biotransformation reactions are classified as phase I and II reactions. Uridine 5'-diphospho (UDP)-glucuronosyltransferases (UGTs) are a superfamily of phase II enzymes which have roles in the conjugation of xenobiotics or endogenous compounds, including drugs and bilirubin, with glucuronic acid to make them easier to excrete. The method the human body uses to achieve glucuronidation may be affected by a large interindividual variation due to changes in the sequences of the genes encoding these enzymes. In the last five years, the study of the genetic variants of the UGTs at a molecular level has become important due to its association with several diseases and the ability to predict adverse events due to drug metabolism. In the present review, the structure and the prominent genetic variants of the UGT1A subfamily and their metabolic and clinical implications are described.

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.

PLoS One 2018; 13:e0193108. [PMID: 29474382 PMCID: PMC5825038 DOI: 10.1371/journal.pone.0193108] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2017] [Accepted: 02/05/2018] [Indexed: 11/30/2022] Open
Abstract
Background Neonatal jaundice (NNJ) is common, but few root cause analyses based on national quality registries have been performed. An online registry was established to estimate the incidence of NNJ in Turkey and to facilitate a root cause analysis of NNJ and its complications. Methods A multicenter prospective study was conducted on otherwise healthy newborns born at ≥35 weeks of gestation and hospitalized for only NNJ in 50 collaborator neonatal intensive care units across Turkey over a 1-year period. Patients were analyzed for their demographic and clinical characteristics, treatment options, and complications. Results Of the 5,620 patients enrolled, 361 (6.4%) had a bilirubin level ≥25 mg/dL on admission and 13 (0.23%) developed acute bilirubin encephalopathy. The leading cause of hospital admission was hemolytic jaundice, followed by dehydration related to a lack of proper feeding. Although all infants received phototherapy, 302 infants (5.4%) received intravenous immunoglobulin in addition to phototherapy and 132 (2.3%) required exchange transfusion. The infants who received exchange transfusion were more likely to experience hemolytic causes (60.6% vs. 28.1%) and a longer duration of phototherapy (58.5 ± 31.7 vs. 29.4 ± 18.8 h) compared to infants who were not transfused (p < 0.001). The incidence of short-term complications among discharged patients during follow-up was 8.5%; rehospitalization was the most frequent (58%), followed by jaundice for more than 2 weeks (39%), neurological abnormality (0.35%), and hearing loss (0.2%). Conclusions Severe NNJ and bilirubin encephalopathy are still problems in Turkey. Means of identifying at-risk newborns before discharge during routine postnatal care, such as bilirubin monitoring, blood group analysis, and lactation consultations, would reduce the frequency of short- and long-term complications of severe NNJ.

Guidelines on the management of abnormal liver blood tests. Gut 2018; 67:6-19. [PMID: 29122851 PMCID: PMC5754852 DOI: 10.1136/gutjnl-2017-314924] [Citation(s) in RCA: 282] [Impact Index Per Article: 47.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Revised: 10/06/2017] [Accepted: 10/15/2017] [Indexed: 12/13/2022]
Abstract
These updated guidelines on the management of abnormal liver blood tests have been commissioned by the Clinical Services and Standards Committee (CSSC) of the British Society of Gastroenterology (BSG) under the auspices of the liver section of the BSG. The original guidelines, which this document supersedes, were written in 2000 and have undergone extensive revision by members of the Guidelines Development Group (GDG). The GDG comprises representatives from patient/carer groups (British Liver Trust, Liver4life, PBC Foundation and PSC Support), elected members of the BSG liver section (including representatives from Scotland and Wales), British Association for the Study of the Liver (BASL), Specialist Advisory Committee in Clinical Biochemistry/Royal College of Pathology and Association for Clinical Biochemistry, British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN), Public Health England (implementation and screening), Royal College of General Practice, British Society of Gastrointestinal and Abdominal Radiologists (BSGAR) and Society of Acute Medicine. The quality of evidence and grading of recommendations was appraised using the AGREE II tool. These guidelines deal specifically with the management of abnormal liver blood tests in children and adults in both primary and secondary care under the following subheadings: (1) What constitutes an abnormal liver blood test? (2) What constitutes a standard liver blood test panel? (3) When should liver blood tests be checked? (4) Does the extent and duration of abnormal liver blood tests determine subsequent investigation? (5) Response to abnormal liver blood tests. They are not designed to deal with the management of the underlying liver disease.

Abstract
OBJECTIVE To compare the performance and accuracy of the JM-103 transcutaneous bilirubinometer and Bilistick System in measuring total serum bilirubin for the early identification of neonatal hyperbilirubinemia. STUDY DESIGN The study was performed on 126 consecutive term and near-term (⩾36 weeks' gestational age) jaundiced newborns in Cairo University Children Hospital NICU, Egypt. Total serum bilirubin was assayed concurrently by the clinical laboratory and Bilistick System and estimated using the JM-103 transcutaneous bilirubin instrument. Bland-Altman analysis was used to evaluate the agreement between determinations. RESULT The limits of agreement of the Bilistick System (-5.8 to 3.3 mg dl-1) and JM-103 system (-5.4 to 6.0 mg dl-1) versus the clinical laboratory results were similar. CONCLUSION The Bilistick System is an accurate alternative to transcutaneous (TcB) determination for early diagnosis and proper management of the neonatal jaundice.

Abstract
BACKGROUND The assessment of jaundice in outpatient neonates is problematic. Visual assessment is inaccurate, and more exact methodologies are cumbersome and/or expensive. Our goal in this study was to assess the accuracy of a technology based on the analysis of digital images of newborns obtained using a smartphone application called BiliCam. METHODS Paired BiliCam images and total serum bilirubin (TSB) levels were obtained in a diverse sample of newborns (<7 days old) at 7 sites across the United States. By using specialized software, data on color values in the images ("features") were extracted. Machine learning and regression analysis techniques were used to identify features for inclusion in models to predict an estimated bilirubin level for each newborn. The correlation between estimated bilirubin levels and TSB levels was calculated. In addition, the sensitivity and specificity of the estimated bilirubin levels in identifying newborns with high TSB levels were calculated by using 2 recommended decision rules for jaundice screening. RESULTS Estimated bilirubin levels were calculated and compared with TSB levels in a diverse sample of 530 newborns (20.8% African American, 26.3% Hispanic, and 21.2% Asian American). The overall correlation was 0.91, and correlations among white, African American, Hispanic, and Asian American newborns were 0.92, 0.90, 0.91, and 0.88, respectively. The sensitivities of BiliCam in identifying newborns with high TSB levels were 84.6% and 100%, respectively, by using 2 decision rules; specificities were 75.1% and 76.4%, respectively. CONCLUSIONS BiliCam provided accurate estimates of TSB values, demonstrating that an inexpensive technology that uses commodity smartphones could be used to effectively screen newborns for jaundice.

Abstract
INTRODUCTION Jaundice is one of the most common causes of admission to hospital in newborns which is often associated with several complications. AIM The present study was conducted to evaluate the effect of H. vulgare in reducing jaundice. MATERIALS AND METHODS In this double-blind, randomized controlled trials 70 term infants hospitalized due to jaundice in 2014 were enrolled. Control group was treated with full-time phototherapy alone using LED except when the infants were breastfed and case group with phototherapy, as per the protocol in the control group, along with and topical H. vulgare seed flour three times a day. Data were analysed using and analysis of covariance (ANCOVA) and paired t-test in SPSS version 16.0. RESULTS There was a significant difference in mean indirect bilirubin level between the two groups p<0.05, such that the mean indirect bilirubin level was higher in the control group. Furthermore, no significant difference was seen in direct bilirubin level between the two groups at discharge p>0.05. CONCLUSION H. vulgare flour can cause decrease in indirect bilirubin. Because the rate of decrease in indirect bilirubin can be effective in preventing severe complications due to bilirubinemia, H. vulgare can be used as a complementary therapy to treat jaundice.

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.
