Shahshahani MA, Liu X, Norman M, Tilden EL, Ahlberg M. Midwifery continuity of care, breastfeeding and neonatal hyperbilirubinemia: A retrospective cohort study. Midwifery 2024; 136:104079. [PMID: 38945104 DOI: 10.1016/j.midw.2024.104079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 06/24/2024] [Accepted: 06/25/2024] [Indexed: 07/02/2024]
Abstract
AIM To examine the association between Midwifery Continuity of Care (MCoC) and exclusive breastfeeding at hospital discharge and neonatal hyperbilirubinemia. METHODS A matched cohort design was employed using data from the Swedish Pregnancy Register. The study included 12,096 women who gave birth at a university hospital in Stockholm, Sweden from January 2019 to August 2021. Women and newborns cared for in a MCoC model were compared with a propensity-score matched set receiving standard care. Risk ratios (RR) were determined with 95 % confidence intervals (CI) based on the matched cohort through modified Poisson regressions with robust standard error. A mediation analysis assessed the direct and indirect effects of MCoC on exclusive breastfeeding at hospital discharge and neonatal hyperbilirubinemia and to what extent the association was mediated by preterm birth. FINDING Findings showed that MCoC was associated with a higher chance of exclusive breastfeeding rate (RR: 1.06, 95 % CI: 1.01-1.12) and lower risk of neonatal hyperbilirubinemia (RR: 0.51, 95 % CI: 0.32-0.82) compared with standard care. Mediation analysis demonstrated that lower preterm birth accounted for approximately 28 % of total effect on the reduced risk of neonatal hyperbilirubinemia. DISCUSSION/CONCLUSION This matched cohort study provided preliminary evidence that MCoC models could be an intervention for improving exclusive breastfeeding rates at hospital discharge and reducing the risk of neonatal hyperbilirubinemia.

Abstract
OBJECTIVES To determine the clinical features of bilirubin encephalopathy in preterm infants (pBE) in Japan. METHODS We performed a retrospective, nationwide questionnaire-based survey. The initial survey determined the number of children with pBE who were born after 2000. Using a structured questionnaire, the second survey clarified the clinical manifestations and characteristics of children with pBE, including demographic data, neurological symptoms, and MRI and auditory brainstem response (ABR) findings. RESULTS The initial survey identified 41 pBE infants from 18 institutions. After exclusion of patients included in previous studies, clinical information was collected from 30 patients (21 boys and 9 girls) during the secondary survey. The median gestational age was 26 weeks and the median birthweight was 846 g. Chronic lung disease and symptomatic patent ductus arteriosus were common neonatal complications. Head control was observed in 63% and functional gait in 17% of patients. Purposeful hand use was seen in 57% and verbal communication in 50% of patients. MRI showed T2 hyperintensities in the globus pallidus of 29 of 30 patients. ABR abnormalities were present in 11 of 15 patients. None of the variables were significantly different between the 2017 and 2021 surveys. CONCLUSIONS The pBE infants had severely impaired gross motor function and relatively preserved manual function and verbal communication. MRI and ABR findings aid in the diagnosis of pBE.

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

Ning Y, Lam A, Reilly M. Estimating risk ratio from any standard epidemiological design by doubling the cases. BMC Med Res Methodol 2022; 22:157. [PMID: 35637431 PMCID: PMC9150348 DOI: 10.1186/s12874-022-01636-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 05/12/2022] [Indexed: 12/04/2022] Open
Abstract
Background Despite the ease of interpretation and communication of a risk ratio (RR), and several other advantages in specific settings, the odds ratio (OR) is more commonly reported in epidemiological and clinical research. This is due to the familiarity of the logistic regression model for estimating adjusted ORs from data gathered in a cross-sectional, cohort or case-control design. The preservation of the OR (but not RR) in case-control samples has contributed to the perception that it is the only valid measure of relative risk from case-control samples. For cohort or cross-sectional data, a method known as ‘doubling-the-cases’ provides valid estimates of RR and an expression for a robust standard error has been derived, but is not available in statistical software packages. Methods In this paper, we first describe the doubling-of-cases approach in the cohort setting and then extend its application to case-control studies by incorporating sampling weights and deriving an expression for a robust standard error. The performance of the estimator is evaluated using simulated data, and its application illustrated in a study of neonatal jaundice. We provide an R package that implements the method for any standard design. Results Our work illustrates that the doubling-of-cases approach for estimating an adjusted RR from cross-sectional or cohort data can also yield valid RR estimates from case-control data. The approach is straightforward to apply, involving simple modification of the data followed by logistic regression analysis. The method performed well for case-control data from simulated cohorts with a range of prevalence rates. In the application to neonatal jaundice, the RR estimates were similar to those from relative risk regression, whereas the OR from naive logistic regression overestimated the RR despite the low prevalence of the outcome. Conclusions By providing an R package that estimates an adjusted RR from cohort, cross-sectional or case-control studies, we have enabled the method to be easily implemented with familiar software, so that investigators are not limited to reporting an OR and can examine the RR when it is of interest.

Abstract
To avoid brain damage in newborn infants, effective tools for prevention of excessive neonatal hyperbilirubinemia are needed. The objective of this study was to evaluate a new transcutaneous bilirubinometer (JAISY). For this purpose, 930 bilirubin measurements were performed in 141 newborn infants born near-term or at term (gestational age 35–41 weeks; postnatal age 1–6 days; 71 boys; including 29 infants with darker skin) and compared to those of a previously validated instrument (JM105). In each infant, the mean of three repeated measurements in the forehead was calculated for each instrument, followed by a similar measurement on the chest. The bilirubin values varied between 0 and 320 µmol/l (0–18.8 mg/dl). There was a high degree of agreement with significant correlations between bilirubin values measured with the two devices on the forehead (Pearson’s r = 0.94, p < 0.001) and the chest (r = 0.94, p < 0.001). The correlations remained after stratifying the data by gestational age, postnatal age and skin color. The coefficient of variation for repeated bilirubin measurements was 8.8% for JAISY and 8.0% for JM105 (p = 0.79). In conclusion, JAISY provides accurate and reproducible information on low to moderately high bilirubin levels in newborn infants born near-term or at term.

Abstract
OBJECTIVE To evaluate the relationship between Doppler and biometric ultrasound parameters measured at diagnosis and perinatal adverse outcome in a cohort of late-onset growth-restricted (FGR) fetuses. METHODS This was a multicenter retrospective study of data obtained between 2014 and 2019 including non-anomalous singleton pregnancies complicated by late-onset FGR (≥ 32 weeks), which was defined either as abdominal circumference (AC) or estimated fetal weight (EFW) < 10th percentile for gestational age or as reduction of the longitudinal growth of AC by over 50 percentiles compared to ultrasound scan performed between 18 and 32 weeks of gestation. We evaluated the association between sonographic findings at diagnosis of FGR and composite adverse perinatal outcome (CAPO), defined as stillbirth or at least two of the following: obstetric intervention due to intrapartum fetal distress, neonatal acidemia, birth weight < 3rd percentile and transfer to the neonatal intensive care unit (NICU). RESULTS Overall, 468 cases with complete biometric and umbilical, fetal middle cerebral and uterine artery (UtA) Doppler data were included, of which 53 (11.3%) had CAPO. On logistic regression analysis, only EFW percentile was associated independently with CAPO (P = 0.01) and NICU admission (P < 0.01), while the mean UtA pulsatility index (PI) multiples of the median (MoM) > 95th percentile at diagnosis was associated independently with obstetric intervention due to intrapartum fetal distress (P = 0.01). The model including baseline pregnancy characteristics and the EFW percentile was associated with an area under the receiver-operating-characteristics curve of 0.889 (95% CI, 0.813-0.966) for CAPO (P < 0.001). A cut-off value for EFW corresponding to the 3.95th percentile was found to discriminate between cases with and those without CAPO, yielding a sensitivity of 58.5% (95% CI, 44.1-71.9%), specificity of 69.6% (95% CI, 65.0-74.0%), positive predictive value of 19.8% (95% CI, 13.8-26.8%) and negative predictive value of 92.9% (95% CI, 89.5-95.5%). CONCLUSIONS Retrospective data from a large cohort of late-onset FGR fetuses showed that EFW at diagnosis is the only sonographic parameter associated independently with the occurrence of CAPO, while mean UtA-PI MoM > 95th percentile at diagnosis is associated independently with intrapartum distress leading to obstetric intervention. © 2021 The Authors.

Abstract
BACKGROUND With the improvement of living standards in recent years, people are paying increasing attention to neonatal jaundice. Yinzhihuang granule is a common Chinese herbal drug for the treatment of neonatal jaundice. The aim of this paper was to study the efficacy of acupressure-assisted Yinzhihuang granule in the treatment of neonatal jaundice by meta-analysis. METHODS We performed a search in the databases of PubMed, Embase, Cochrane Library, Chinese Journal Full-text Database (CNKI), VIP, Wanfang Science and Technology Journal Full-text Database, and Chinese Biomedical Literature Search Database (CBM) for articles on the therapeutic effect of acupressure-assisted Yinzhihuang granule on neonatal jaundice from database establishment to October 2021. The software Endnote X9 was used to check and eliminate the articles, screen the articles according to the required inclusion and exclusion criteria, extract the data, and perform quality evaluation according to the risk of bias tool of Cochrane Collaboration. The software Stata 15.1 and RevMan 5.3 were used to record the data, and a meta-analysis was performed on the effective rate of acupressure-assisted Yinzhihuang granule in the treatment of neonatal jaundice, according to serum total bilirubin values after treatment and duration of jaundice. And show the efficacy of Yinzhihuang particles through these results. The reliability of the results was assessed by sensitivity analysis. Funnel plots were used to test the publication bias of the articles. RESULTS A total of 3 articles were included. The results of meta-analysis showed that when acupressure-assisted Yinzhihuang granule was used to treat neonatal jaundice, the effective rate of the test group was not significantly different from that in the control group; the serum total bilirubin level in the test group was significantly lower than that in the control group after treatment; the duration of jaundice in the test group was significantly shorter than that in the control group. DISCUSSION Acupressure combined with Yinzhihuang granule is effective in treating neonatal jaundice, which has a positive effect on reducing the level of serum total bilirubin and reducing the duration of jaundice.

The development and validation of a predictive model for neonatal phototherapy outcome using admission indicators. Front Pediatr 2022; 10:745423.

Abstract
Delayed exchange transfusion therapy (ETT) after phototherapy failure for newborns with severe hyperbilirubinemia could lead to serious complications such as bilirubin encephalopathy (BE). In this current manuscript we developed and validated a model using admission data for early prediction of phototherapy failure. We retrospectively examined the medical records of 292 newborns with severe hyperbilirubinemia as the training cohort and another 52 neonates as the validation cohort. Logistic regression modeling was employed to create a predictive model with seven significant admission indicators, i.e., age, past medical history, presence of hemolysis, hemoglobin, neutrophil proportion, albumin (ALB), and total serum bilirubin (TSB). To validate the model, two other models with conventional indicators were created, one incorporating the admission indicators and phototherapy failure outcome and the other using TSB decrease after phototherapy failure as a variable and phototherapy outcome as an outcome indicator. The area under the curve (AUC) of the predictive model was 0.958 [95% confidence interval (CI): 0.924-0.993] and 0.961 (95% CI: 0.914-1.000) in the training and validation cohorts, respectively. Compared with the conventional models, the new model had better predictive power and greater value for clinical decision-making by providing a possibly earlier and more accurate prediction of phototherapy failure. More rapid clinical decision-making and interventions may potentially minimize occurrence of serious complications of severe neonatal hyperbilirubinemia.

Abstract
Abstract
Background Preterm neonates frequently experience hypernatremia (plasma sodium concentrations >145 mmol/l), which is associated with clinical complications, such as intraventricular hemorrhage.
Study design In this single center retrospective observational study, the following 7 risk factors for hypernatremia were analyzed in very low gestational age (VLGA, below 32 weeks) neonates: gestational age (GA), delivery mode (DM; vaginal or caesarian section), sex, birth weight, small for GA, multiple birth, and antenatal corticosteroids. Machine learning (ML) approaches were applied to obtain probabilities for hypernatremia.
Results 824 VLGA neonates were included (median GA 29.4 weeks, median birth weight 1170 g, caesarean section 83%). 38% of neonates experienced hypernatremia. Maximal sodium concentration of 144 mmol/l (interquartile range 142–147) was observed 52 hours (41–65) after birth. ML identified vaginal delivery and GA as key risk factors for hypernatremia. The risk of hypernatremia increased with lower GA from 22% for GA ≥ 31–32 weeks to 46% for GA < 31 weeks and 60% for GA < 27 weeks. A linear relationship between maximal sodium concentrations and GA was found, showing decreases of 0.29 mmol/l per increasing week GA in neonates with vaginal delivery and 0.49 mmol/l/week after cesarean section. Sex, multiple birth and antenatal corticosteroids were not associated hypernatremia.
Conclusion VLGA neonates with vaginal delivery and low GA have the highest risk for hypernatremia. Early identification of neonates at risk and early intervention may prevent extreme sodium excursions and associated clinical complications.

[PMID: 32146227 DOI: 10.1016/j.ejogrb.2020.02.028] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2019] [Revised: 02/13/2020] [Accepted: 02/15/2020] [Indexed: 10/25/2022]
Abstract
OBJECTIVE To assess the prevalence and risk of adverse perinatal outcomes in early-term (37+0-38+6 weeks), full-term (39+0-40+6 weeks), late-term (41+0-41+6 weeks), and post-term (>42+0 weeks) deliveries with spontaneous labor onset. STUDY DESIGN A population-based cohort with data from the Medical Birth Registry Norway (MBRN) and Statistics Norway (SSB) was conducted. The study population consisted of 665,244 women with cephalic singleton live births at term or post-term with spontaneous labor onset during the period of 1999-2014 in Norway. Maternal, obstetric, and fetal characteristics were obtained from the MBRN. Maternal education data were obtained from the SSB. The prevalence rates of adverse perinatal outcomes for each gestational age (GA) group were estimated. Inter-group differences were detected with Chi square tests. Multivariable regression analysis adjusted for maternal age, educational level, smoking, parity, maternal diabetes, and preeclampsia was used to assess adverse outcome prevalence for early- late-, and post-term births compared to full-term births. RESULTS Deliveries at early-term were associated with an increased prevalence of neonatal jaundice, polyhydramnios, small for gestational age (SGA) status, respiratory support, and neonatal intensive care unit (NICU) admission compared with deliveries at GAs of 39-43 weeks (p < 0.001). Low 5-min Apgar scores and newborn antibiotic treatment occurred at an increased prevalence in both early-term and post-term infants, relative to the full-term group (p < 0.001). The prevalence of oligohydramnios, meconium-stained amniotic fluid, and newborn birth injuries increased with increasing GA. CONCLUSIONS More perinatal morbidity was observed among early-term infants compared to infants with later term deliveries, underscoring the need for cautious management of low-risk early-term deliveries.

Abstract
BACKGROUND Neonatal jaundice is a common finding in newborns in Asia, including Indonesia. In some cases, the serum total bilirubin levels exceeds the 95th percentile for hours of life (neonatal hyperbilirubinemia). Severe neonatal hyperbilirubinemia (NH) could lead to kernicterus and neonatal death. Glucose-6-Phosphage Dehydrogenase (G6PD) genetic variations and deficiency have been reported in several studies to be associated with NH. This study aimed to analyze the G6PD genetic variations and its activity in neonates with and without hyperbilirubinemia in the Deutromalay Indonesian population. METHODS Deoxyribose Nucleic Acid (DNA) was isolated from peripheral blood of 116 and 115 healthy term neonates with and without hyperbilirubinemia. All infants underwent the following laboratory examinations: routine hematologic evaluation, Coombs test, G6PD activity measurement using the Randox kit method, and serum total bilirubin level. All exons of the G6PD gene were targeted for deep sequencing using MiSeq (Illumina). An association study of G6PD polymorphisms with NH was performed using PLINK. RESULTS The prevalence of G6PD deficiency in neonates with and without hyperbilirubinemia in Indonesian Deutromalay population were 1.72% (95% Confidence Interval (CI): 0.6-4.1%) and 1.74% (95% CI: 0.7-4.1%), respectively. The most common G6PD polymorphisms, i.e. rs1050757/c.* + 357A > G, rs2230037/c.1311C > T, and rs2071429/c.1365-13 T/IVS11, were identified. However, none of those polymorphisms and their haplotype were associated with NH (p > 0.05, Odds Ratio (OR) ~1.00). The prevalence of G6PD mutations in neonates with and without hyperbilirubinemia were 6.8% (95% CI: 2.3-11.5%) and 6.9% (95% CI: 2.3-11.6%), respectively. The most frequently identified G6PD mutation was the Viangchan variant (p.V291 M), which was followed by the Canton (p.R459L) and Vanua Lava (p.L128P) variants. Two novel mutations were identified both in case (p.V369A, p.I167F) and control (p.L474=, p.I36T) groups. CONCLUSION The prevalence of G6PD deficiency is low in neonates with or without hyperbilirubinemia in Deutromalay Indonesian population. The majority of G6PD mutations identified among Indonesian Deutromalay population in this study are Viangchan, Canton and Vanua Lava variants.

Abstract
IMPORTANCE Neonatal hyperbilirubinemia can cause lifelong neurodevelopmental impairment (kernicterus) even in high-resource settings. A better understanding of the incidence and processes leading to kernicterus may help in the design of preventive measures. OBJECTIVES To determine incidence rates of hazardous hyperbilirubinemia and kernicterus among near-term to term newborns and to evaluate health care professional adherence to best practices. DESIGN, SETTING, AND PARTICIPANTS This population-based nationwide cohort study used prospectively collected data on the highest serum bilirubin level for all infants born alive at 35 weeks' gestation or longer and admitted to neonatal care at all 46 delivery and 37 neonatal units in Sweden from 2008 to 2016. Medical records for newborns with hazardous hyperbilirubinemia were evaluated for best neonatal practices and for a diagnosis of kernicterus up to 2 years of age. Data analyses were performed between September 2017 and February 2018. EXPOSURES Extreme (serum bilirubin levels, 25.0-29.9 mg/dL [425-509 μmol/L]) and hazardous (serum bilirubin levels, ≥30.0 mg/dL [≥510 μmol/L]) neonatal hyperbilirubinemia. MAIN OUTCOMES AND MEASURES The primary outcome was kernicterus, defined as hazardous neonatal hyperbilirubinemia followed by cerebral palsy, sensorineural hearing loss, gaze paralysis, or neurodevelopmental retardation. Secondary outcomes were health care professional adherence to national guidelines using a predefined protocol with 10 key performance indicators for diagnosis and treatment as well as assessment of whether bilirubin-associated brain damage might have been avoidable. RESULTS Among 992 378 live-born infants (958 051 term births and 34 327 near-term births), 494 (320 boys; mean [SD] birth weight, 3505 [527] g) developed extreme hyperbilirubinemia (50 per 100 000 infants), 6.8 per 100 000 infants developed hazardous hyperbilirubinemia, and 1.3 per 100 000 infants developed kernicterus. Among 13 children developing kernicterus, brain injury was assessed as potentially avoidable for 11 children based on the presence of 1 or several of the following possible causes: untimely or lack of predischarge bilirubin screening (n = 6), misinterpretation of bilirubin values (n = 2), untimely or delayed initiation of treatment with intensive phototherapy (n = 1), untimely or no treatment with exchange transfusion (n = 6), or lack of repeated exchange transfusions despite indication (n = 1). CONCLUSIONS AND RELEVANCE Hazardous hyperbilirubinemia in near-term or term newborns still occurs in Sweden and was associated with disabling brain damage in 13 per million births. For most of these cases, health care professional noncompliance with best practices was identified, suggesting that a substantial proportion of these cases might have been avoided.

Abstract
Our objective was to assess the relationship between hyperbilirubinemia with and without kernicterus and metabolic profile at newborn screening. Included were 1,693,658 infants divided into a training or testing subset in a ratio of 3:1. Forty‐two metabolites were analyzed using logistic regression (odds ratios (ORs), area under the receiver operating characteristic curve (AUC), 95% confidence intervals (CIs)). Several metabolite patterns remained consistent across gestational age groups for hyperbilirubinemia without kernicterus. Thyroid stimulating hormone (TSH) and C‐18:2 were decreased, whereas tyrosine and C‐3 were increased in infants across groupings. Increased C‐3 was also observed for kernicterus (OR: 3.17; 95% CI: 1.18–8.53). Thirty‐one metabolites were associated with hyperbilirubinemia without kernicterus in the training set. Phenylalanine (OR: 1.91; 95% CI: 1.85–1.97), ornithine (OR: 0.76; 95% 0.74–0.77), and isoleucine + leucine (OR: 0.63; 95% CI: 0.61–0.65) were the most strongly associated. This study showed that newborn metabolic function is associated with hyperbilirubinemia with and without kernicterus.

Abstract
Diagnosis and timely treatment of neonatal jaundice is critical to preventing its dangerous side effects. Knowing the predisposing factors of neonatal jaundice is still a serious debate, which can be effective in controlling jaundice and the primary problem. The aim of this study was to evaluate maternal risk factors that contribute to the Hyperbilirubinemia among newborns admitted to Imam Khomeini and Ziaeean hospitals during 2015. We collected random samplings for the current study. Medical records for all newborns with jaundice were examined for risk factors associated with Hyperbilirubinemia. All variables were analyzed by SPSS software, version 19. Chi-square test and T-test were applied to evaluate qualitative and quantitative data, respectively. Our findings revealed that maternal age, weight, BMI, WBC, Hb, PLT, birth in the first pregnancy, numbers of pregnancies and prolonged delivery were significantly associated with bilirubin levels. Preventing the risk correlated with maternal factors or identifying neonates with these risk factors is important in effective management of infants. Therefore, the evaluation of neonatal jaundice in health care services should always be considered as a fundamental policy.

Abstract
BACKGROUND Indirect neonatal hyperbilirubinemia (INH) is a common neonatal disorder worldwide which can remain benign if prompt management is available. However there is a higher morbidity and mortality risk in settings with limited access to diagnosis and care. The manuscript describes the characteristics of neonates with INH, the burden of severe INH and identifies factors associated with severity in a resource-constrained setting. METHODS We conducted a retrospective evaluation of anonymized records of neonates hospitalized on the Thai-Myanmar border. INH was defined according to the National Institute for Health and Care Excellence guidelines as 'moderate' if at least one serum bilirubin (SBR) value exceeded the phototherapy threshold and as 'severe' if above the exchange transfusion threshold. RESULTS Out of 2980 records reviewed, 1580 (53%) had INH within the first 14 days of life. INH was moderate in 87% (1368/1580) and severe in 13% (212/1580). From 2009 to 2011, the proportion of severe INH decreased from 37 to 15% and the mortality dropped from 10% (8/82) to 2% (7/449) coinciding with the implementation of standardized guidelines and light-emitting diode (LED) phototherapy. Severe INH was associated with: prematurity (< 32 weeks, Adjusted Odds Ratio (AOR) 3.3; 95% CI 1.6-6.6 and 32 to 37 weeks, AOR 2.2; 95% CI 1.6-3.1), Glucose-6-phosphate dehydrogenase deficiency (G6PD) (AOR 2.3; 95% CI 1.6-3.3), potential ABO incompatibility (AOR 1.5; 95% CI 1.0-2.2) and late presentation (AOR 1.8; 95% CI 1.3-2.6). The risk of developing severe INH and INH-related mortality significantly increased with each additional risk factor. CONCLUSION INH is an important cause of neonatal hospitalization on the Thai-Myanmar border. Risk factors for severity were similar to previous reports from Asia. Implementing standardized guidelines and appropriate treatment was successful in reducing mortality and severity. Accessing to basic neonatal care including SBR testing, LED phototherapy and G6PD screening can contribute to improve neonatal outcomes.

Abstract
Introduction: The efficacy of massage to treat neonatal hyperbilirubinemia remains controversial. We conducted a systematic review and meta-analysis to explore the influence of massage on the neonatal hyperbilirubinemia. Methods: We search PubMed, Embase, Web of science, EBSCO, and Cochrane Library databases through November 2017 for randomized controlled trials (RCTs) assessing the effect of massage on neonatal hyperbilirubinemia. This meta-analysis is performed using the random-effect model. Results: Six RCTs involving 357 patients are included in the meta-analysis. Overall, compared with the control group in neonatal hyperbilirubinemia, massage therapy is associated with substantially reduced serum bilirubin level within 4 d (mean difference (MD) = -2.31; 95% CI = -2.92 to -1.70; p < .00001) and transcutaneous bilirubin level within 4 d for neonatal hyperbilirubinemia (MD = -1.97; 95% CI = -2.55 to -1.39; p < .00001), but results no remarkable impact on serum bilirubin level on 2 d (MD = -0.82; 95% CI = -2.16-0.52; p = .23), transcutaneous bilirubin level on 2 d (MD = -0.17; 95% CI = -1.34 to 1.00; p = .77), frequency of defecation daily on 2 d (MD = 0.57; 95% CI = -0.03 to 1.16; p = .06), and frequency of defecation daily within 4 d (MD = 0.83; 95% CI = -0.11 to 1.76; p = .08). Conclusions: Massage therapy can significantly reduce serum bilirubin level and transcutaneous bilirubin level within 4 d, but demonstrates no influence on serum bilirubin level and transcutaneous bilirubin level on 2 d, frequency of defecation daily on 2 and 4 d for neonatal hyperbilirubinemia.

Abstract
Late preterm infants are at risk for short-term morbidities. We report that late preterm singletons conceived with fertility treatment have increased risk for admission to the neonatal intensive care unit and respiratory support compared with spontaneously conceived infants. Fertility treatment may be a risk factor to consider in managing late preterm infants.

Abstract
A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.

Lee BK, Le Ray I, Sun JY, Wikman A, Reilly M, Johansson S. Haemolytic and nonhaemolytic neonatal jaundice have different risk factor profiles. Acta Paediatr 2016; 105:1444-1450. [PMID: 27173507 DOI: 10.1111/apa.13470] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2015] [Revised: 04/19/2016] [Accepted: 05/10/2016] [Indexed: 12/23/2022]
Abstract
AIM This study examined maternal and pregnancy risk factors for haemolytic and nonhaemolytic neonatal jaundice in a large population-based cohort study. METHODS We conducted a cohort study of 1 019 220 singleton live births from the Swedish medical birth register from 1987 to 2002, using information on neonatal jaundice and maternal and pregnancy characteristics. Diagnoses of gestational hypertensive disorders were obtained by linkage to the national inpatient register. Multivariate logistic regression analysis provided odds ratios for the risk factors of both forms of jaundice. RESULTS A total of 6057 (0.6%) births were affected by haemolytic jaundice and 36 869 (3.6%) by nonhaemolytic jaundice. The strongest risk factors for haemolytic jaundice were maternal alloimmunisation, blood group O and neonatal jaundice in older siblings. For nonhaemolytic jaundice, the strongest risk factors were preterm birth, neonatal jaundice in older siblings, maternal origin from East or South-East Asia and maternal obesity. We estimated that 13% of haemolytic jaundice was attributable to alloimmunisation and 39% of nonhaemolytic jaundice was attributable to preterm birth. CONCLUSION Haemolytic and nonhaemolytic neonatal jaundice had different risk factor profiles. Interventions to reduce maternal alloimmunisation, preterm birth and maternal obesity may lower the prevalence of neonatal jaundice and the risk of consequent neurological complications.

Extreme hyperbilirubinemia and rescue exchange transfusion in California from 2007 to 2012. J Perinatol 2016; 36:853-7. [PMID: 27442156 DOI: 10.1038/jp.2016.106] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2016] [Revised: 03/29/2016] [Accepted: 04/05/2016] [Indexed: 11/08/2022]
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.
