Prevalence of macrosomic newborn and maternal and neonatal complications in a high-risk maternity

Abstract Objective Evaluate the prevalence of macrosomic newborns (birth weight above 4000 grams) in a high-risk maternity from 2014 to 2019, as well as the maternal characteristics involved, risk factors, mode of delivery and associated outcomes, comparing newborns weighing 4000-4500 grams and those weighing above 4500 grams. Methods This is an observational study, case-control type, carried out by searching for data in hospital's own system and clinical records. The criteria for inclusion in the study were all patients monitored at the service who had newborns with birth weight equal than or greater than 4000 grams in the period from January 2014 to December 2019, being subsequently divided into two subgroups (newborns with 4000 to 4500 grams and newborns above 4500 grams). After being collected, the variables were transcribed into a database, arranged in frequency tables. For treatment and statistical analysis of the data, Excel and R software were used. This tool was used to create graphs and tables that helped in the interpretation of the results. The statistical analysis of the variables collected included both simple descriptive analyzes as well as inferential statistics, with univariate, bivariate and multivariate analysis. Results From 2014 to 2019, 3.3% of deliveries were macrosomic newborns. The average gestational age in the birth was 39.4 weeks. The most common mode of delivery (65%) was cesarean section. Diabetes mellitus was present in 30% of the deliveries studied and glycemic control was absent in most patients. Among the vaginal deliveries, only 6% were instrumented and there was shoulder dystocia in 21% of the cases. The majority (62%) of newborns had some complication, with jaundice (35%) being the most common. Conclusion Birth weight above 4000 grams had a statistically significant impact on the occurrence of neonatal complications, such as hypoglycemia, respiratory distress and 5th minute APGAR less than 7, especially if birth weight was above 4500 grams. Gestational age was also shown to be statistically significant associated with neonatal complications, the lower, the greater the risk. Thus, macrosomia is strongly linked to complications, especially neonatal complications.

Objetivo: identificar mediante análise macroscópica e ra-diográfica as alterações estruturais em tecidos dentários afetados pela hiperbilirrubinemia, normalmente constatada a partir do sinal clínico de icterícia e provoca o desenvolvi-mento de pigmentos intrínsecos esverdeados nas estruturas dentárias. Materiais e Métodos: a amostra foi composta por 31 dentes decíduos dividida em grupo controle (n= 7) e grupo experimental (n= 24). As análises macroscópicas foram efetuadas por meio de fotografias individuais padroniza-das e as radiográficas obtidas com aquisições de imagem a 9 mA, 70 kVp, distância de 8cm, exposição 0,4 segundos e com XDR Sensor®. As imagens foram convertidas pelo software XDR Brasil 3.1.6 e padronizadas pelo programa GIMP 2.10.22. Os dados da média simples do histograma foram analisados pelo teste T-Student e Mann-Whitney (p<0,05). Resultados: demonstraram a maior intensidade de pigmentação em região cervical da raiz, com diferença de densidade radiográfica estaticamente significante na porção radicular entre os grupos experimental e controle (p=0,043). Na análise da densidade radiográfica da estrutura radicular do grupo experimental houve diferença estatica-mente significante (p=0,016) entre os terços cervical e apical. Discussão: Os dados evidenciaram que dentes pigmentados pela hiperbilirrubinemia não possuem alterações na densidade mineral nos terços coronários. Conclusão: Dentes com pigmentação esverdeada bilirrubina possuem diferenças na densidade radiográfica so-mente na região radicular.

Aim: is to identify, through macroscopic and radio-graphic analysis, structural changes in dental tissues affected by hyperbilirubinemia, usually seen from the clinical sign of icterus and causes the development of intrinsic greenish pigments in dental structure. Materials and Methods: The sample consisted of 31 primary teeth divided into a control group (n=7) and an experimental group (n=24). Macroscopic analyzes were performed using standardized individual photographs and radiographic ones obtained by image acquisition at 9 mA, 70 kVp, 8cm distance, 0.4 seconds exposure and with XDR Sensor®. The images were converted by XDR Brasil 3.1.6 software and standardized by GIMP 2.10.22 software. The Histogram's simple mean data were analyzed by T-Student and Mann-Whitney tests (p<0.05). Results: showed intensity of pigmentation in the cervical region of the root, with a statistically significant difference in the root portion between the experimental and control groups (p=0.043. In the analysis of radiographic density of the root structure of the experimental group, there was a statistically significant difference (p= 0.016) between the cervical and apical thirds. Discussion: The data showed that teeth pigmented by hyperbilirubinemia do not have changes in mineral density in the coronary thirds. Conclusion: Greenish pigments teeth have differences in radiographic density only in the root structure.

Enfermedad hemolítica del feto y del recién nacido por aloanticuerpos contra el antígeno M / Hemolytic disease in fetuses and newborns due to antibodies against the M-antigen

Resumen | Hay pocos reportes de enfermedad hemolítica del feto y del recién nacido causada por aloanticuerpos contra el sistema de antígenos MNS, especialmente, porque los anticuerpos que se generan contra estos antígenos son del tipo IgM, los cuales tienen reactividad a temperaturas inferiores a los 37 °C, y, por lo tanto, no son de importancia clínica. A pesar de ello, se han reportado casos con presencia de anticuerpos anti-M de tipo IgG causantes de la enfermedad hemolítica del recién nacido e, incluso, casos de muerte intrauterina por incompatibilidad materno-fetal en el sistema MNS. El proceso hemolítico se asemeja al causado por los anticuerpos anti-Kell, con anemia progresiva por supresión hematopoyética que induce la destrucción de precursores hematopoyéticos en la médula ósea y ausencia de reticulocitos en la periferia. Se reporta el caso de una mujer con 38,5 semanas de gestación, que presentó discrepancia en la hemoclasificación directa y en la inversa. Como resultado, el recién nacido fue positivo en la prueba de Coombs directa sin que existiera incompatibilidad ABO con la madre. La correlación de estos resultados llevó a la detección de un anticuerpo anti-M en el suero materno. El diagnóstico definitivo fue posible gracias a la discrepancia en la hemoclasificación de la sangre materna. A pesar de que los anticuerpos anti-M usualmente no desempeñan un papel importante en la enfermedad hemolítica perinatal, este caso resalta la importancia de determinar la presencia de diferentes anticuerpos que pueden ser de vital interés a la hora de prevenir resultados graves asociados con dicha condición. Además, abre la puerta a nuevas recomendaciones relacionadas con la tamización y el tratamiento temprano de la hemólisis en los recién nacidos.

Abstract | There are few case reports of hemolytic disease in fetuses and newborns (HDFN) caused by alloantibodies against the MNS blood group system. The reason for this dearth is that antibodies toward these antigens are usually IgM, which not only cannot cross the placental circulation but also react at temperatures below 37°C. They are, therefore, of minimal clinical importance. Nevertheless, cases have been reported in which the presence of anti-M IgG antibodies caused severe HDFN and even intrauterine death in the presence of maternal-fetal MNS incompatibility indicating that they could have a high clinical impact. The hemolytic pattern observed in these cases is similar to that caused by anti-Kell antibodies. Progressive anemia is mediated and developed through hematopoietic suppression inducing the destruction of bone marrow precursor cells with the resulting absence of reticulocytes in peripheral blood. This occurred in the case of a woman at 38.5 weeks of gestation who showed a discrepancy between direct and reverse blood type determination. A direct Coombs test was performed on the newborn's blood, which was positive in the absence of maternal-fetal ABO incompatibility. Further tests were performed and anti-M antibodies were found in the maternal serum screening. Our final diagnosis was largely due to discrepancy issues in maternal blood. Although anti-M antibodies do not usually play a significant role in HDFN, this case stresses the importance of identifying the presence of antibodies that can be crucial in preventing HDFN and lead to new recommendations for the screening and prompt treatment of hemolysis in newborns.

The predictive value of general movement assessment combined total bilirubin for motor development outcomes in infants with severe neonatal jaundice / 中国医师杂志

Objective:To study the predictive values of the general movements (GMs) assessment combined total bilirubin for motor development outcomes in infants with severe neonatal jaundice.Methods:From June of 2014 to June of 2019, infants with severe neonatal jaundice in Chenzhou First People′s Hospital were enrolled in the study. Inclusion criteria included , the serum total bilirubin was measured at the time of admission, corrected gestational age of 37 to 48 weeks. General assessment were carried out when the infant was stable. The patients were regularly followed-up until the age of 12months to evaluate the predictive values.Results:A total of 204 patients with severe neonatal jaundice were enrolled in the study, with mean serum total bilirubin value (485.4±109.6)μmol/L. They were divided into two groups according to the outcome of motor development. The total bilirubin value, the proportion of abnormal GMs and dangerous total bilirubin level in the abnormal group were significantly higher than those in the normal group (all P<0.05). 13 cases (6.4%) were normal in the torsion stage of GMs; 191 cases (93.6%) were abnormal, including 164 cases (85.9%) of poor repertoire (PR) and 27 cases (14.1%) of cramped-synchronized (CS). Abnormal GMs and total bilirubin were the risk factors of abnormal motor development ( OR=4.651, 1.017, P<0.05). The predictive values of abnormal GMs for abnormal motor development outcomes were as following: sensitivity 100%, specificity 8.4%, negative predictive value (NPV) 100%. The predictive values of CS for cerebral palsy were as following: sensitivity 63.2%, specificity 97.8%, NPV 96.0%. Receiver operating characteristic (ROC) curve showed that the area under the curve predicted by GMs and total bilirubin was 0.765 and 0.757, respectively. The area under the curve of motor dysplasia predicted by combining the two was 0.854. Conclusions:The evaluation of general movement assessment combined total bilirubin has certain clinical predictive value for the outcomes of motor development in infants with severe neonatal jaundice.

Remote monitoring of neonatal jaundice in newborns with ABO hemolytic disease / 浙江大学学报·医学版

OBJECTIVE@#To explore the feasibility of remote monitoring of neonatal jaundice in newborns with ABO hemolytic disease.@*METHODS@#Forty six neonates of gestational age >35 weeks with ABO hemolytic disease admitted to Women's Hospital, Zhejiang University School of Medicine from January 20th, 2020 to February 29th, 2020 were enrolled in the study (study group). The newborns were followed up at home after discharge, the transcutaneous bilirubin (TCB) levels were measured by parents using the provided device and the results were sent to the doctor by smart phone using the installed APP. Fifty six newborns with ABO hemolytic disease admitted in 2018 who received conventional outpatient follow-up after discharge served as the control group. The demographic characteristics, total serum bilirubin (TSB) level during hospitalization, number of outpatient visit and rate of re-admission due to rebound hyperbilirubinemia were compared between the two groups.@*RESULTS@#There were no significant differences between the two groups in gestational age, birth weight, delivery mode, gender, length of the first hospitalization, TSB level before phototherapy and before discharge, and the managements during the first hospitalization (all @*CONCLUSIONS@#The remote follow-up for neonatal jaundice at home can effectively reduce the number of outpatient visits without increasing the risk of readmission and severe neonatal hyperbilirubinemia for newborns with ABO hemolytic disease.

Breastfeeding Experiences of Taiwanese Mothers of Infants with Breastfeeding or Breast Milk Jaundice in Certified Baby-Friendly Hospitals

PURPOSE: The purpose was to explore the breastfeeding experiences of mothers of infants with breast-feeding or breast milk jaundice. METHODS: In-depth qualitative interviews and content analysis were conducted with nine mothers of newborns with breastfeeding and/or breast milk jaundice who breastfed their babies during the first year postpartum. RESULTS: Mothers' experiences can be described in four phases and six themes. (1) Prenatal stage: build breastfeeding belief, i.e., breastfeeding is best and a natural behavior, without awareness of neonatal jaundice; (2) stage after neonatal jaundice started to appear: include two themes, questioning beliefs in breastfeeding and happiness in being a mother. Mothers lacked knowledge and ignored the threat of neonatal jaundice, mainly focused on their physical discomforts and worried about insufficient breast milk; they also felt an intimate mothereinfant bond through breastfeeding; (3) stage when newborns had confirmed diagnosis of breastfeeding or breast milk jaundice that required medical attention: include two themes, diagnosis of breastfeeding or breast milk jaundice and phototherapy caused negative emotions and regaining original beliefs about breastfeeding. They struggled through emotional swings and inconsistent advices about whether phototherapy and formula supplementation are needed. Then, they decided breastfeeding or breast milk jaundice is only temporary and retrieved initial beliefs of breastfeeding. (4) Stage after neonatal jaundice faded and mothers continued breastfeeding: insisting and adapting. CONCLUSION: Breastfeeding mothers were unaware of neonatal jaundice until medical attention was required; they experienced physical and mental distress and gradually learned to manage jaundice while insisting on breastfeeding through their breastfeeding beliefs and happiness in being mothers.

InfLuences on accuracy of automated image-based estimation of neonataL serum biLirubin LeveL using smartphone appLication under different circumstances / 中华围产医学杂志

Objective To study the influence factors on the accuracy of a smartphone software application (APP) , which is an automated image-based bilirubin (AIB) testing technique for neonatal bilirubin. Methods This was a prospective study involving 179 jaundiced neonates admitted to the Department of Neonatology of the Affiliated Xuzhou Hospital of Southeast University from August to December, 2017. If blood sampling was required to determine total serum bilirubin (TSB), the transcutaneous bilirubin (TcB) and AIB on the sternum (glabella or the visible darkest yellow area were tested in 36 cases at the same time) were also tested. The concentrations of AIB were measured using a mobile phone-based neonatal jaundice monitoring APP with images taken by OPPO R11 smartphone (55 cases were also taken by Huawei Mate 8 and iPhone 6). The accuracy and non-inferiority of AIB comparing with TcB, the correlation and consistency between AIB and TSB and the value of AIB in predicting TSB were analyzed. Non-inferiority trial, student's t test, variance analysis, Pearson's correlation analysis, Bland-Altman plots and receiver operating characteristic (ROC) curve were used as statistical methods. ResuLts A total of 179 neonates were enrolled in this study with the mean gestational age of (36.2±2.1) weeks and the mean birth weight of (2 871±735) g. Based on all data, the mean difference between the absolute value of AIB minus TSB (|AIB － TSB|) and the absolute value of TcB minus TSB (|TcB － TSB|) was 0.77 mg/dl (1 mg/dl=17.1 μmol/L) with the 95%CI of (0.60-0.95) mg/dl, suggesting that the accuracy of AIB was not inferior to that of the TcB. Furthermore, AIB was not inferior to TcB in its accuracy in different subgroups based upon the time after birth ( ≤ 48 h and >48 h), gestational age (≤35 weeks and >35 weeks) and in the daytime subgroup. In the nighttime subgroup, the mean difference between ∣ AIB － TSB ∣ and ∣ TcB － TSB ∣ was 1.47 mg/dl [95%CI: (1.08-1.87) mg/dl], which indicated that the accuracy of AIB was inferior to that of the TcB. There were good correlation (r=0.788) and highly consistency between AIB and TSB based on all data [96.4% (238/247) of the samples were within the 95% limits of agreement of (－4.75 to 5.71) mg/dl]. Such results were also found in different subgroups, such as smartphone brands, detection areas, the time after birth and gestational age. The correlation and consistency between AIB and TSB in daytime subgroup (r=0.924, 98.4%) were obviously stronger than those of the nighttime subgroup (r=0.727, 87.5%). The mean difference between the absolute value of ocular value minus TSB (|ocular value－TSB|)and|AIB－TSB|was 2.13 mg/dl [95%CI: (1.68-2.58) mg/dl], implying a superior accuracy of AIB than ocular estimation. The areas under the ROC curves, the sensitivity and the specificity of AIB for the prediction of TSB >10, >15 and >20 mg/dl were 0.94, 93% and 85%; 0.89, 75% and 87%; and 0.84, 50% and 88%, respectively. ConcLusions AIB is not inferior to TcB in accuracy, and is significantly superior to ocular estimation. There are good correlation and strong consistency between AIB and TSB. The accuracy of AIB, and the correlation and consistency between AIB and TSB are less likely to be affected by the time after birth, gestational age, smartphone brands and areas being examined, but are largely affected when examining during nighttime. Therefore, it is recommended to detect AIB at daytime with bright natural light.

From suffering to resignation: Grounded Theory approach to maternal experience with newborn in phototherapy / Do sofrimento à resignação: experiência materna com recém-nascido em fototerapia na abordagem Grounded Theory

Abstract Objectives: understanding the experience of puerperal womenwith newborn in phototherapy treatment in rooming-in care. Methods: qualitative research analyzed according to the Grounded Theory and the results discussed in the light of Symbolic Interactionism. The interviews were audiotaped and transcribed in full. The theoretical saturation was based on the analysis of the 15th interview with puerperal women, undergoing the experience in the maternity of the Public Hospital of São Paulo State. Results: from the analysis emerged four categories (sub processes): getting disappointed with the bad news; feeling recluse, separated from her baby, accountable and with not enough support for care; resigning to the protective role of mother of a baby in suffering and at risk; seeking strategies to deal with the situation. From the realignment of these categories (sub processes) emerged the core category (process): from suffering to resignation in order to deal with the maternal experience with NB in phototherapy. Conclusions: the symbolic intervening component, mother's protective role, prompted her to attempt to cope with the challenging experience by feeling compelled to exercise the function of caretaker. The same way that the rooming-in care team emerged in the experience of the mother, using the same symbol, to hold her accountable for constant vigilance in maintaining the integrity of baby's vision.

Resumo Objetivos: compreender a experiência de puérperas com recém-nascido em tratamento fototerápico em alojamento conjunto. Métodos: pesquisa qualitativa analisada segundo a Teoria Fundamentada nos Dados e os resultados discutidos à luz do Interacionismo Simbólico. As entrevistas foram audio-gravadas e transcritas na íntegra. A saturação teórica deu-se a partir da análise da 15ª entrevista com puérperas, vivenciando a experiência em maternidade de Hospital Público do Estado de São Paulo. Resultados: da análise emergiram quatro categorias (subprocessos): decepcionando-se com a má notícia; sentindo-se reclusa, apartada do bebê, responsabilizada e com apoio insuficiente para o cuidado; resignando-se ao papel protetor de mãe de bebê em sofrimento e em risco; buscando estratégias para lidar com a situação. Do realinhamento dessas categorias (subprocessos) emergiu a categoria central (processo): do sofrimento à resignação para enfrentar a experiência materna com recém-nascido em fototerapia. Conclusões: o componente interveniente simbólico, papel protetor de mãe, impulsionou-a a tentativas de lidar com a experiência desafiante ao se sentir compelida ao exercício de cuidadora. Da mesma forma que, a equipe do alojamento conjunto emergiu na vivência dessa mãe, utilizando-se do mesmo símbolo, para responsabilizá-la pela vigilância constante na manutenção da integridade da visão do bebê.

A study on the correlation of miRNA in breast milk and neonatal breast milk associated jaundice / 中国新生儿科杂志

Objective To study the relationship of microRNA (miR) in breast milk and neonatal breast milk associated jaundice.Method From Sep.to Dec.2016,neonates with severe hyperbilirubinemia caused by breast milk were selected as the observation group,and breast-fed neonates without jaundice were selected as the control group.Their breast milk were collected,and the expression profile of miR in the breast milk was examined using miR sequencing.The variation of miR profile was screened using bioinformatics method,and miR related to neonatal breast milk associated jaundice was studied and the target genes were predicted.Result The breast milk contained many miRs associated with immunity regulation and metabolism,including miR-148-3p,miR-30a-5p,miR-146-5p,let-7f-5p,miR-181-5p,miR-22-3p,and miR-182-5p.The expressions of miR-30a-5p,miR-146a-5p and miR-141-3p in the observation group were significantly higher than the control group,and the differences were 2.600,2.038 and 1.899-fold,respectively.Uridine diphosphate glucuronosyl transferase1A1 gene was one of the target genes of miR-141-3p.Conclusion Breast milk miR may influence the growth and development,immunity regulation and metabolism of newborns.Some miRs,such as miR-141-3p,may be correlated with neonatal breast milk associated jaundice.

Neonatal and early infantile jaundice: assessment by the use of the smartphone / 中国新生儿科杂志

Objective To assess the accuracy of automated image－based bilirubin ( AIB ) of newborns or early infants obtained using a smartphone application called BiliScan for Newborn Jaundice . Method Jaundiced neonates (gestational age≥35 weeks) and early infants (postnatal age≤60 days) from out－patient or in－patient of our hospital during November 2016 to September 2017 were prospectively included.The total serum bilirubin ( TSB ), transcutaneous bilirubin ( TcB ) and AIB on chest were completed simultaneously on hospitalization , pre phototherapy, 0 h and 12 ～24 h after cessation of phototherapy for in－patients, and after diagnosis of breast－feeding jaundice for out－patients participants.The AIB were all detected by smartphone with an application of BiliScan for Newborn Jaundice .Statistical analysis was performed by SPSS 20.0.Result A total of 296 sets of data were enrolled from 194 neonates or infants in this study.The accuracy of AIB was not inferior to the TcB (The difference between the mean of the absolute value of AIB －TSB and the absolute value of TcB －TSB was 0.77 mg/dl, 95% confidence interval were 0.63 ～0.91 mg/dl).These results of the subgroups from male and female term infants , postnatal age＞2 days and the value of TSB≤20 mg/dl were similar to the overall results.However, in the subgroup of TSB＞20 mg/dl, the accuracy of AIB was lower than that of TcB compared to TSB.There were good correlation (r＝0.824) and consistency (96.5% samples lay within the 95% limits of agreement ) between AIB and TSB.In the subgroup of 10 mg/dl ＜TSB≤20 mg/dl, the correlation and consistency between AIB and TSB were better than those of the subgroups of TSB ≤10 mg/dl and TSB ＞20 mg/dl. Furthermore, TSBs of 97.5% neonates were not beyond AIB plus 3.80 mg/dl.Conclusion When 10 mg/dl＜TSB≤20 mg/dl, the accuracy of AIB was not inferor to TcB , and the correlation and consistency between AIB and TSB were relatively superior.The application BiliScan for Newborn Jaundice was suitable for dynamic monitoring moderate jaundice of neonates and early infants at home.

Objective To explore the clinical effect of live Bacillus Subtilis and Enterococcus Faecium granulescombined with blue light irradiation in the treatment of neonatal jaundice.Methods 90 patients with neonatal jaundice were randomly divided into control group and observation group.The control group received the blue light treatment,the observation group was given blue light irradiation combined with live Bacillus Subtilis and Enterococcus Faecium granules treatment,the patients were treated for 7 days.The clinical efficacy,serum bilirubin and main indicators of complex constant time were observed in the two groups.Results After treatment,the total effective rate of the observation group was 95.6％,which of the control group was 68.9％,the difference was statistically significant (x2 =5.473,P ＜ O.05).After treatment for 1 day,3 days,7 days,the serum bilirubin values of the observation group were (185.6 ± 25.1) μmol/L,(136.7 ± 19.1) μmol/L,(82.1 ± 10.3) μmol/L,respectively,which of the control group were (205.3 ± 26.4) μmol/L,(184.1 ± 20.3) μmol/L,(128.4 ± 16.7) μmol/L,the differences between the two groups were statistically significant (t =3.628,11.408,15.829,all P ＜ 0.05).The recovery time of serum bilirubin in the observation group was (7.1 ± 2.4) d,which of the control group was (12.9 ±3.1) d,there was significant difference between the two groups (t =9.924,P ＜ 0.05).The hospitalization time of observation group was (3.5 ± 1.1) d,which of the control group was (5.8 ± 1.5) d,the difference between the two groups was statistically significant (t =8.295,P ＜ 0.05).Conclusion Live Bacillus Subtilis and Enterococcus Faecium granules combined with blue light irradiation in the treatment of neonatal jaundice is helpful to improve the clinical efficacy,reduce the treatment time and improve the clinical symptoms.

The reliability of transcutaneous bilirubin measurements at different sites before and after phototherapy compared with total serum bilirubin in neonates / 中国新生儿科杂志

Objective To evaluate the accuracy of the transcutaneous bilirubin (TcB) at different sites including the chest (covered and uncovered),forehead and scapula,compared with total serum bilirubin (TSB) before and after phototherapy.Method Neonates who underwent blood test of TSB together with the average TcB at chest over 6 mg/dl from September 2015 to July 2016 in our Hospital were enrolled in our study.TcB measurements were done by the transcutaneous bilirubinometer (JH20-1 C) at the sites of the chest,forehead and scapula within 30 minutes after venous or arterious blood sampling for testing TSB after admission.An area of 2 cm diameter over the left chest was covered during phototherpy.TSB was tested immediately and within 12 ～ 24 hours after phototherapy,while TcB was measured within 0.5 hour after blood sampling at the covered sites over the left chest,right chest,forehead and scapula.IBM SPSS 20.0 software was used for data analysis.Data were compared via Pearson correlation analysis,ANOVA of repeated measurement data,student's t test and Bland-Altman analysis.Result A total of 437 data were collected from 364 neonates were enrolled in our study.Before phototherapy,the values of TcB at different sites were highly correlated and consistent with TSB (P ＜ 0.05),especially taken from the chest (the difference value of TcB and TSB-1.2 ± 2.3 mg/dl).Immediately and within 12 ～ 24 hours after the phototherapy,the values of TSB and TcB taken from the covered left chest showed the highest consistency (-1.2±2.3 mg/dl and-0.5 ± 1.6 mg/dl).When TSB exceeded 15 mg/dl before phototherapy,the difference between TSB and TcB taken from chest was 1.5 ± 1.6 mg/dl,while if TSB was below 15 mg/dl,the difference was-1.9 ± 1.9 mg/dl.They were significantly different (P ＜ 0.001).And difference between TSB and TcB taken from chest was not affected by gender gestational age,birth weight,days of birth and different measurements.When TcB taken from the covered or uncovered chest was less than the TSB threshold value of 3.3 mg/dl for phototherapyl,or the TcB of the left covered sternum lower than the threshold value of 2.6 mg/ml for cessation of phototherapy,97.5％ of the TSB would not exceed the corresponding value.Conclusion The TcB values of both uncovered chest before phototherapy and covered chest after phototherapy were highly consistent with TSB,and could be applied in the replacement of TSB in the assessment and management of neonatal jaundice.

Comparison of the effect and prognosis of intermittent blue light and continuous blue light therapy for neonatal jaundice / 中国基层医药

Objective To observe the effect of intermittent and continuous blue light therapy for pathological neonatal jaundice,and to evaluate the prognosis of newborns.Methods 214 patients with pathologic neonatal jaundice who treated with blue light irradiation were slected,they were randomly divided into two groups according to the admission number combined with single and double numbers,107 patients in each group.Group A received continuous blue light irradiation treatment.Group B received intermittent blue light irradiation.The clinical efficacy and prognosis of children,blue light exposure time,serum total bilirubin (TBiL) recovery time,the hospitalization time and the adverse reactions during the treatment were observed.The levels of serum TBiLwere measured before and after light exposure 3,5 days.Results The total effective rate of group B was 97.18％ (104/107),which was higher than that of group A [90.65 ％ (97/107)],the difference was statistically significant (x2 =10.30,P ＜ 0.05).The time of blue light irradiation and hospital stay time of group B were (71.59 ± 7.05) d and (11.51 ± 1.23) d,respectively,which were significantly shorter than those of group A [(79.54 ± 6.82) d and (13.64 ± 1.18) d],the differences were statistically significant (u =11.42,9.87,all P ＜ 0.05).The level of TBiL of group B was (96.28 ± 10.25) μmol/L,which was significantly lower than (104.52 ± 10.31) μmol/L of group A (u =8.94,P ＜ 0.05).The incidence rate of adverse reactions in group B was 2.55％ (4/157),which was lower than that in group A [7.01％ (11/157)],the difference was statistically significant (x2 =9.66,P ＜ 0.05).The prognosis of neonatal in the two groups was good.Conclusion The intermittent and continuous blue light in the treatment of pathological neonatal jaundice has good clinical effect and the neonatal prognosis is good.The clinical efficacy of intermittent blue light irradiation is better,which can significantly shorten the treatment time and has higher safety.

Close monitoring of transcutaneous bilirubin ensures better outcome in neonates with hyperbilirubinemia / 中华围产医学杂志

Objective To explore the influence of regular measurement of transcutaneous bilirubin (TcB) on clinical outcome of neonatal hyperbilirubinemia.Methods Healthy term and late-preterm newborns (gestational age ≥ 35 weeks) born between January 1 and December 31,2013 at Peking University Third Hospital were reviewed retrospectively.All neonates were divided into monitoring group (n=1 071)or control group (n=2 437) according to whether regular monitoring of TcB was performed.General clinical information and TcB levels on admission were recorded.The incidence of hyperbilirubinemia and readmission for hyperbilirubinemia,level of bilirubin and length of hospital stay were compared between the two groups.Chi-square test or independent sample t test were used for statistical analysis.Results (1) The incidence of hyperbilirubinemia and readmission rate for hyperbilirubinemia were lower in monitoring group when compared with control group [4.7％ (50/1 071) vs 7.1％ (172/2 437) and 1.3％ (14/1 071) vs 3.3％ (81/2 437) respectively,P＜0.05].There was no significant difference of bilirubin level and hospital stay between the two groups (P＞0.05).(2) Of all the 222 hyperbilirubinemia patients,the number of neonates with gestational age ＜37 weeks,37-38 weeks and ＞38 weeks was 26 (11.7％),33(14.9％) and 163(73.4％),respectively.There was no significant difference of gestational age,birth weight and gender proportion between the two groups.(3) The follow-up rate in January was 41.5％ (49/118),and the mean follow-up rate in February,April,July and October (with revised follow-up methods) was 83.1％ (345/415),higher than that in January (x2=82.505,P＜0.01).(4) The first three causes of hyperbilirubinemia in all 222 patients were early-onset breast milk jaundice (72 cases,32.4％),perinatal causes (60 cases,27.0％) and unknown reasons (50 cases,22.5％).The first three causes of hyperbilirubinemia in monitoring group (50 cases) were unknown reasons (24 cases,48.0％),early-onset breast milk jaundice (14 cases,28.0％) and hemolysis (9 cases,18.0％).Those in the control group (172 cases) were early-onset breast milk jaundice (58 cases,33.7％),perinatal causes (57 cases,33.1％) and unknown reasons (26 cases,15.1％).Conclusions Regular monitoring of TcB can reduce the incidence ofhyperbilirubinemia and the readmission for hyperbilirubinemia.
