Active clinical trials for "Hyperbilirubinemia, Neonatal"

The purpose of this research study is to more accurately measure the amount of true red blood cell breakdown (hemolysis) in newborn babies with potentially problematic blood type mismatch with their mothers (ABO incompatibility), and to examine how the true level of red blood cell destruction relates to other laboratory tests obtained in newborns with jaundice. A better understanding of the true amount of red blood cell destruction that is caused by blood type mismatch, as well as how it relates with other laboratory tests ordered for ABO incompatibility and red blood cell destruction, would help avoid unnecessary testing, treatment and prolonged hospital stays in such babies.

The objective of this study was to investigate whether infants with total serum bilirubin > 450 umol/L in the neonatal period and no symptoms or no more than early acute bilirubin encephalopathy develop long term sequelae with impairment of motor development, hearing and executive function compared with a control group.

This will be a prospective clinical study conducted with the approval of the Clinical Research Ethics Committee. The influence of phototherapy lights on the accuracy of pulse oximetry will be investigated.

Due to actual standard of neonatal care bilirubin is monitored in neonates several times after birth to avoid hyperbilirubinemia. As the peak is often one or two days after discharge from hospital a more precise predication than the actual one is desirable to avoid needlessly follow-ups. The precision of an algorithm to predict bilirubin values 24-48h into the future is evaluated in this study.

Neonatal hyperbilirubinaemia (NH) is common among healthy neonates and normally resolves within a week. Untreated pathological hyperbilirubinaemia, however, can result in long-term neurological sequelae, which compromise childhood development, or may result in perinatal death. True population-based data from middle to low-income countries are scarce and NH contribution to morbidity and mortality remains unclear. With this study the investigators aim at assessing the prevalence of neonatal hyperbilirubinaemia in a cohort of newborns in a maternity hospital in Kinshasa, the Democratic Republic of Congo, and at evaluating the possible risk factors for NH in the mother and the baby.

Prospective comparison of measurement of bilirubin in jaundiced newborns by a transcutaneous device (bilirubinometer) and laboratory analysis of blood samples. We hypothesise that correlation of the two measurements depend on bilirubin level, gestational age as well as postnatal age.

A team of researchers at Rice University in partnership with clinicians at Queen Elizabeth Central Hospital created BiliSpec, a low-cost battery-powered reader designed to immediately quantify serum bilirubin levels from a small drop of whole blood applied to a lateral flow strip. The simple and affordable BiliSpec system offers a faster and more cost-effective means to detect neonatal jaundice in under-resourced clinics and determine when phototherapy is needed. The goal of this study is to validate the accuracy of the BiliSpec device in measuring bilirubin levels in neonates relative to the laboratory spectrophotometric bilirubinometer and transcutaneous bilirubinometer measurements.

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.
