Filter by:This project aims to test a novel smartphone application, Picterus, which provides a cheaper, patient-friendly, and more readily means of neonatal jaundice detection. For this purpose, the study aims to collect data from newborns with a broad range of bilirubin levels and high melanin content in a population in Botswana.
The hemolytic disease of newborns (HDN) is one of the most significant risk factors for hyperbilirubinemia. Studies have shown that end-tidal carbon monoxide-corrected (ETCOc) correlated with the rate of bilirubin production in the body and thus can be a good surrogate to quantify hemolysis and identifying the high-risk infants. However, there is insufficient clinical evidence regarding the early prediction of hemolytic hyperbilirubinemia using ETCOc. This study hypothesizes that early postnatal ETCOc levels are significantly associated with the risk of hemolytic hyperbilirubinemia requiring treatments within 14 days after birth, and early postnatal ETCOc can be a good indicator for early prediction of hemolysis. In addition, the investigators aim to investigate the relationship between the characteristics of treatments for hyperbilirubinemia and ETCOc.
Neonatal hyperbilirubinemia ( NHB ) has many causes and is difficult to diagnose, and genetic factors play an important role in the metabolism of bilirubin. However, there is no literature report on the correlation between jaundice gene polymorphism and clinical manifestation polymorphism in big data population. This project intends to conduct a prospective observational study led by the Department of Pediatrics of the Sixth Affiliated Hospital of Sun Yat-sen University and in conjunction with a multi-center cooperative hospital : ( 1 ) A total of 2,000 NHB neonatal dry blood spot samples were included for 24 genetic screening tests for 29 NHB-related genetic diseases. The construction of the gene database was completed and the carrying and pathogenicity of NHB-related genes in the population was analyzed to provide a scientific basis for the selection of mutation sites for large-scale NHB gene screening ; ( 2 ) Collect neonatal clinical data and percutaneous bilirubin levels through the hospital inpatient system and the ' percutaneous jaundice meter home monitoring + software doctor-patient interconnection ' method, complete the construction of the intelligent NHB clinical database, and analyze the impact of jaundice-related genes on NHB ; ( 3 ) Integrated analysis to understand the differences in the carrying rate of pathogenic genes in different degrees and special types of jaundice, and to explore the differences in the degree of jaundice carrying single or multiple jaundice pathogenic genes. This study will evaluate the feasibility of jaundice gene screening program in the detection of jaundice-related inherited metabolic diseases, and provide a basis for early treatment and prevention of NHB.
Phototherapy is the most frequently used treatment in neonatology when serum bilirubin levels exceed physiological limits. Light-emitting diodes (LEDs) are become routinely used for phototherapy in neonates with hyperbilirubinemia. Blue LED light with peak emission around 460 nm is regarded as the most suitable light sources for phototherapy and they recommended by most neonatal guidelines. However, the effectiveness of phototherapy with narrow-band LED light sources can be increased by expanding the spectral range of incident radiation within the absorption of bilirubin due to the strongly marked heterogeneity absorption properties of bilirubin in a different microenvironment. Longer wavelength light, such as green light, is expected to penetrate the infant's skin deeper. It is still controversial whether the use of green light has any advantage over blue light. The most effective and safest light source and the optimal method to evaluate phototherapy, however, remain unknown.The aim of this study was to compare, at equal light irradiance, the clinical efficacy of broad spectrum blue- green LED with blue narrow spectral band phototherapy device.
Evidence for benefited newborns following delayed cord clamping (DCC), including increasing hemoglobin and hematocrit levels, improving iron stores, and decreasing need for blood transfusion and incidence of intraventricular hemorrhage, in term or preterm infants led the American College of Obstetricians and Gynecologists (ACOG) to recommend a delayed cord clamping at least 30-60 seconds in vigorous term and preterm infants at birth. Although DCC has been found to be beneficial to infants, the additional blood provided by DCC could increase the incidence of jaundice that requires phototherapy and the hyperbilirubinemia, and the time prolonged by DCC might jeopardize timely resuscitation efforts, if needed. The acid-base status in umbilical cord blood at birth reflects the newborn's aerobic and anaerobic intrauterine metabolisms and is an objective measure of the fetal exposure and response to hypoxia during labour. Gestational diabetes mellitus (GDM) is a condition in which glucose intolerance develops during pregnancy. It has been estimated in 2009 that nearly 7% of pregnancies are complicated by diabetes and approximately 86% of these cases represented women with GDM. The Hyperglycemia and Adverse Pregnancy Outcome study (HAPO) revealed that the infants of diabetic mothers (IDMs) are at increased risk of neonatal hypoglycemia, hyperbilirubinemia, shoulder dystocia, and birth trauma. And newborns to diabetic mothers are at increased risk of neonatal respiratory distress syndrome (RDS) and hypoxia, a major cause of admission in neonatal intensive care units. There is little direct evidence on the implementation of delayed umbilical cord clamping in the risk group of IDMs. Therefore, it no clear that the effectiveness and impairment of DCC in IDMs. Therefore, the investigators conducted a prospective study in performing DCC in the infants of diabetic mothers versus the newborns with early cord clamping (ECC) to assess the effect of DCC on neonatal bilirubin levels, hyperbilirubinemia incidence, acid-base status and hypoxia in IDMs.
We hypothesized that adopting a lower rather than a higher threshold for phototherapy discontinuation will be associated with reduced rates of rebound hyperbilirubinemia in term and late preterm neonates with hemolytic disease of newborn. Objectives: The investigators aimed to compare the safety of implementing low-threshold, compared to high- threshold, of TSB for phototherapy interruption in term and late preterm neonates with hemolytic disease of newborn.
Neonatal Glucose-6-phosphate Dehydrogenase(G6PD) Deficiency is one of the significant reason for neonatal hyperbilirubinemia and even irreversible bilirubin encephalopathy.The neonates may be attacked due to acute infection, eating beans or exposure to oxidative drugs, etc. The main clinical manifestations are hemolytic anemia, and the resulting hyperbilirubinemia. When bilirubin is pretty high in body, bilirubin may spread into brain, and thus cause nervous system damage, and severely affect the prognosis of neonates. Therefore, monitoring and early intervention of jaundice has important significance to prevent further aggravation of jaundice and certain sequelae. Phototherapy and exchange transfusion are mainly suitable methods for severe hyperbilirubinemia, however, patients need to be hospitalized. Yinzhihuang Oral Liquid is a kind of traditional Chinese medicine for jaundice. Many large sample and multicenter clinical studies show that the positive efficacy of Yinzhihuang Oral Liquid in the treatment of neonatal hyperbilirubinemia is exactly confirmed. The purpose of this study is try to detect the treatment effect of Yinzhihuang Oral Liquid on indirect bilirubin in neonates with G-6-PD enzyme deficiency and neonatal hyperbilirubinemia. Try to provide scientific theories for Yinzhihuang Oral Liquid to treat neonates with G-6-PD enzyme deficiency and neonatal hyperbilirubinemia.
Jaundice occurs in most newborn infants. Most jaundice is benign, but because of the potential toxicity of bilirubin, newborn infants must be monitored to identify those who might develop severe hyperbilirubinemia an, in rare cases, acute bilirubin encephalopathy or kernicterus. Jaundice is a commonly observed, usually harmless condition in newborn infants during the first week after birth. However, in some babies the amount of bilirubin pigment can increase to dangerous levels and require treatment. Treatment of jaundice in newborn infants is done by placing them under phototherapy, a process of exposing their skin to light of a specific wavelength band. Fluorescent tubes or halogen lamps have been used as light sources for phototherapy for many years. A light-emitting diode (LED) is a newer type of light source which is power efficient, has a longer life and is portable with low heat production. Several technologies and devices are developed around this LED and specially a compact system. The purpose of this study is to evaluate efficacity of LED phototherapy by comparing with conventional phototherapy (non-LED) and satisfaction of the parents and the professional staff about comfort of this new technology. The newborn infant is placed in a sleeper with the device B' bloo ® which maintains him in position (lap or dorsal) allowing to pass the blue light. This one is generated by the module LED and transmitted in the braid of optical fibers which takes place directly on the mattress of the cradle in which is placed the patient usually. The device is endowed with an hour counter to schedule the time of treatment. The energy illumination varies between 3 and 4 mW / cm ² for an average 3,6 mW / cm ².
In this, here we want to present a new method for analysis variation in gene copy number for patients and carriers of SMA. This is a relative quantitation method and, therefore, relies on the inclusion of one or more internal control or reference sequences; quantitation of DNA is relative to this reference sequence of known copy number. A peak height from within a potentially duplicated or deleted target region is amplified simultaneously with a disomic reference region in a multiplex PCR system.
