Abstract Inverse correlations between serum bilirubin level and obesity had been reported in adults. We aimed to investigate the associations between neonatal hyperbilirubinemia and childhood obesity. Data was obtained from the U.S. Collaborative Perinatal Project (CPP), a multicenter study from 1959 to 1976. Data of serum bilirubin in term newborns were used to observe the association with obesity at age of 7 years. Logistic regression models were performed to calculate adjusted odds ratios (aORs) for obesity. For children from the same mother sharing similar factors, Generalized Estimating Equation (GEE) model was used to correct for intracluster correlation. Relative to newborns with total serum bilirubin (TSB) < 3 mg/dl, there are lower risks for obesity in those with 3 mg/dl ≤ TSB < 6 mg/dl (aOR 0.91; 95%CI 0.81, 1.02), 6 mg/dl ≤ TSB < 9 mg/dl (aOR 0.88; 95%CI 0.78, 0.99), 9 mg/dl ≤ TSB<13 mg/dl (aOR 0.83; 95%CI 0.71, 0.98). By stratifying for subtypes of bilirubin, the inverse correlations only existed in exposure to unconjugated bilirubin. By using the GEE model correcting for intracluster correlations, the results are consistent. In summary, exposure to bilirubin up to 13 mg/dl is inversely associated with obesity at the age of 7 years in term infants.

Objective. To determine whether transcutaneous bilirubin measurements (TcB) before and during phototherapy taken from covered skin during phototherapy correlate with total serum bilirubin (TSB) levels.Study Design. In this prospective observational study, healthy term newborns who required TSB measurements were included. TcB measurements were taken from the forehead before starting and during phototherapy using the BiliChek device. Before starting phototherapy, part of the forehead was covered. Blood for TSB measurement was collected within 5 minutes of TcB measurements. Correlations and mean differences between TcB and TSB before and during phototherapy were calculated.Result. Paired TSB and TcB measurements before and during phototherapy in 151 newborns were performed. The mean gestational age was 38.8 weeks and birth weight was 3.1 kg; 53% were male. Before starting phototherapy, TSB and TcB were183.8±41.6and 190.5 ± 43 μmol/l, respectively. During phototherapy, TSB and TcB were191.8±39.4and187.8±45.3 μmol/l, respectively. Linear regression analysis showed a significant correlation between TcB and TSB before starting phototherapy and during phototherapy (r: 0.85;p<0.001andr: 80.0;p<0.001), respectively. Before starting phototherapy, the mean difference between TSB and TcB was6.2±23.2 μmol/l, with a 95% CI of −39.3 to 51.7 μmol. During phototherapy, the mean difference was −2.8±23.5 μmol/l, with a 95% CI of −48.9 to 43.3 μmol/l.Conclusion. TcB measurements from covered skin in jaundiced term infants during phototherapy correlate with TSB and can be used to monitor bilirubin levels during phototherapy.

Neonatal jaundice is common in newborns affecting over half (50-60%) of all babies in the first week of life. Severe jaundice can result into significant morbidity in the form of kernicterus. Early screening along with, quick treatment of neonatal jaundice helps to reduce the risk of developing severe hyperbilirubinemia, hence Kernicterus. There is strong evidence that screening newborns with hour-specific serum bilirubin level measurements can help in identifying risk of developing hyperbilirubinemia in newborns. There is insufficient data from developing countries regarding hyperbilirubinemia and newborns with and without underlying risk factors for hyperbilirubinemia. This cross sectional study will help the physician to anticipate and manage newborns with high-intermediate zone total serum bilirubin (TSB) and will also help to established specific management guideline for these newborns to prevent bilirubin induced neurological damage (BIND). All term newborns of either gender (fulfilling inclusion criteria) with TSB level at high-intermediate risk zone at 48 hours of life, born at Aga Khan University Hospital were included in this study. Their demographics were recorded in structured proforma. Results were collected and analyzed by SPSS software, version 20.0. A total of 173 newborns were enrolled. There was a female predilection 56.6% (n=98). One-third of the newborns having TSB in high-intermediate risk zone at 48 hours of life progressed to level of significant hyperbilirubinemia requiring treatment (31.2%; n=54). Those who required phototherapy had the mean rate of rise of 5.00 mg/dL/day (0.20 mg/dL/ hr). For future implementations we recommended that early recognition, monitoring and early treatment of neonatal hyperbilirubinemia may help in reducing morbidity. Neonates with high-intermediate risk serum bilirubin level should be followed at 24 hours intervel for assessment and possible treatment.

Each year approximately 60% of the 4 million newborns in the United States become clinically jaundiced. Many receive various forms of evaluation and treatment. Few issues in neonatal medicine have generated such long-standing controversy as the possible adverse consequences of neonatal jaundice and when to begin treatment. Questions regarding potentially detrimental neurologic effects from elevated serum bilirubin levels prompt continuing concern and debate, particularly with regard to the management of the otherwise healthy term newborn without risk factors for hemolysis. Although most data are based on infants with birth weights ≥2500 g, "term" is hereafter defined as 37 completed weeks of gestation. Under certain circumstances, bilirubin may be toxic to the central nervous system and may cause neurologic impairment even in healthy term newborns. Most studies, however, have failed to substantiate significant associations between a specific level of total serum bilirubin (TSB) during nonhemolytic hyperbilirubinemia in term newborns and subsequent IQ or serious neurologic abnormality (including hearing impairment). Other studies have detected subtle differences in outcomes associated with TSB levels, particularly when used in conjunction with albumin binding tests and/or duration of exposure. In almost all published studies, the TSB concentration has been used as a predictor variable for outcome determinations. Factors influencing bilirubin toxicity to the brain cells of newborn infants are complex and incompletely understood; they include those that affect the serum albumin concentration and those that affect the binding of bilirubin to albumin, the penetration of bilirubin into the brain, and the vulnerability of brain cells to the toxic effects of bilirubin.

Background Although phototherapy has been used in clinical practice for 40 years, there is still much debate on how to provide the most efficacious phototherapy. Phototherapy with white reflecting curtains may increase the average spectral irradiance provided, as well as decrease serum bilirubin concentrations at a faster rate in neonates with jaundice.Objective To determine if adding low cost, white, reflecting curtains to a standard phototherapy unit can increase the effectiveness of phototherapy for neonatal jaundice.Methods A randomized, controlled, open trial was conducted at H. Adam Malik and Pirngadi Hospitals, Medan, from May to December 2009. The criteria for inclusion in the study were full term newborns with neonatal jaundice presenting in their first week of life. Single phototherapy with white curtains hanging from the sides of the phototherapy unit (study group, n=30) was compared to single phototherapy without curtains (control group, n=30). The primary outcomes measured were the mean difference in total serum bilirubin levels and average spectral irradiation levels measured at baseline, and after 12 hours and 24 hours of phototherapy.Results The sum of average spectral irradiance in the curtained phototherapy unit was significantly higher than that of the standard phototherapy unit without curtains (P < 0.05). The decrease of total serum bilirubin levels after 12 and 24 hours of phototherapy was significantly greater in the study group (3.71 and 9.7 mg/dl, respectively) than in the control group (0.1 and 3.8 mg/dl, respectively), both P <0.05.Conclusion White, reflecting curtains in phototherapy units was significantly more effective than phototherapy without curtains for treatment of neonatal jaundice.

Purpose: To examine the effects of prayer and meditation on the episodic memory of older adults. Design: Secondary analysis of Health and Retirement Study (HRS). Method: Drawing from a subsample of HRS ( n = 1,135), this study utilized generalized estimating equation regression models to examine the effects of meditation and prayer on changes in episodic memory of older adults over time. Findings: Findings show a statistically significant positive effect of the use of prayer (0.50, p < .05) on episodic memory score at baseline. We also observed a slight gain in episodic memory over time for older adults who used prayer (0.04, p = .05). Meditation was not found to have a statistically significant effect on changes in memory in later life. Conclusion: This study illustrates the benefits of prayer in preserving memory and provides much needed empirical basis for community-level interventions to enhance memory in later life.

Background: G6PD deficiency is one of the common inherited enzymatic disorder associated with high incidence of severe neonatal hyperbilirubinemia. Objectives: To observe G6PD status in male, term neonates with jaundice and its correlation with serum level of bilirubin. Methods: This cross sectional study was conducted on 90 male, term neonates with jaundice, age ranged from 3 to 12 days (Group B) in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU) between July 2007 to June 2008. On the basis of total serum bilirubin (TSB) level, study group was further divided into B1(TSB <15mg/dl), B2(TSB 15-20mg/dl) and B3 (TSB>20mg/dl). For comparison age and sex matched 30 apparently healthy neonates (Group A) were also included in the study. Erythrocyte G6PD level was measured by Spectrophotometric method by using kit of Randox. Serum bilirubin level was measured by standard laboratory technique. For statistical analysis ANOVA, independent sample "t" test and Pearson's correlation coefficient test were performed as applicable by using SPSS windows version-12. Results: In this study, erythrocyte G6PD levels were significantly lower in moderate (p<0.01) and severe (p<0.001) hyperbilirubinemic group in comparison to that of control group . However, this enzyme level was lower in mild group compared to that of control but the difference was statistically non significant. Again, this enzyme levels were significantly lower in moderate (p<0.05) and severe (p<0.01) group than that of mild group and also between severe and moderate hyperbilirubinemic group (p<0.05). In this study, G6PD enzyme deficient were found in 1(3.33%) and 6(20%) subjects of group B2 and B3 respectively. Though, percentage of the subjects with enzyme deficiency were higher in severe group ( B3 ) compared to that of moderate group( B2 ) but the difference was statistically not significant. However, no enzyme deficient patient were found in control group (A) and mild hyperbilirubinemic group (B1). Serum bilirubin level showed significant (p<0.05) positive (r=+.429) correlation with erythrocyte G6PD level in control group (A). On the other hand, this level was negatively correlated with G6PD enzyme in groups B1 (r= -.127), B2 (r=-.120) and B3 ( r= -.671) but significant negative correlation in group B3 (p<0.01). Conclusion: The results of the study revealed that severity of hyperbilirubinemia depends on degree of G6PD deficiency. Therefore, early detection of this enzymopathy and close surveillance of the affected neonates may be important in reducing the complications of severe hyperbilirubinemia.

Abstract Background: Delayed cord clamping (DCC) above one minute is associated with nutritional and developmental benefits newborns. DCC could also lead to elevated serum bilirubin, leading to jaundice that require phototherapy at the early ages of life. However, evidence on the relationship between DCC and outcomes is limited in resource-limited settings.Objective: To evaluate the effect of the time of cord clamping on serum bilirubin level at 24 hours post-birth in an Ethiopian Tertiary Care hospital.Methods: A three-arm, single-blind, randomized controlled trial was conducted between October 2019-January 2020 targeting healthy, full-term neonates. Study participants were randomly assigned into one of the following interventions depending on the timing of cord clamping: immediate cord clamping (<30 seconds), intermediate cord clamping (60 sec), and delayed cord clamping (180 seconds). The primary outcome is serum bilirubin level in the newborns, which was assessed at 24-hour after birth and before they were discharged home. Descriptive analysis was applied to assess differences between groups in terms of demographic, obstetric, and social characteristics of participants, while linear regression model was employed to examine the association between cord clamping time and serum bilirubin level. STATA version 14 was used for statistical analyses.Result: A total of 141 term newborns were included and randomized into the three categories. Demographic, social and obstetrics factors of the women were not different across groups except labor duration that had a P-value < 0.05. Time of cord clamping was not a significant predictor of total serum bilirubin levels at 24 hours post-birth, whereas cord blood total serum bilirubin (coef. 0.24; p<0.05) and bilirubin nomogram high-risk zone (Coef. 6.25; p<0.001) were significant predictors.Conclusion: Time of umbilical cord clamping has no effect on the total serum bilirubin level of neonates at least within 24 hours of birth.

The accuracy of transcutaneous bilirubin meters has been assessed in newborns from various ethnic backgrounds. However, there are limited data on Greek newborns. Our study examined the accuracy of transcutaneous bilirubin measurements in clinically jaundiced healthy-term Greek newborns, using total serum bilirubin as the reference standard, in order to re-evaluate our local guidelines about neonatal jaundice. Clinically jaundiced newborns requiring total serum bilirubin level estimation were recruited prospectively. 368 pairs of total serum bilirubin/transcutaneous bilirubin measurements were taken in 222 newborns, using a direct spectrophotometric device and the BiliCheck device, respectively. The level of agreement between the obtained transcutaneous bilirubin and total serum bilirubin values was assessed. Our data were analysed using the Stata/SE 12.0 (StataCorp LP, USA) statistical programme. The mean (± SD) TSB was 225.4 ± 25.4 μmol/l and the mean (± SD) TcB was 237.9 ± 21.0 μmol/l. The correlation between the values was poor (Pearson’s correlation coefficient 0.439; Lin’s concordance coefficient 0.377 [95% CI 0.301 to 0.453]; P<0.001). The Bland-Altman analysis demonstrated that transcutaneous bilirubin measurements tended to overestimate the total serum bilirubin value (mean difference 12.5 ± 24.9 μmol/l), with wide 95% limits of agreement (–36.2 μmol/l to 61.3 μmol/l). Transcutaneous bilirubin values did not correlate well with total serum bilirubin values, being often imprecise in predicting the actual total serum bilirubin levels. This permits us to continue estimating total serum bilirubin in clinically jaundiced newborns according to our local guidelines, in order to safely decide the appropriate care plan.
