Trial summary

Alterations in the intrauterine environment can have profound effects on fetal development. Diabetes during gestation results in multiple deleterious short-term outcome differences, and is correlated with long-term developmental deficits. Read more about this study

  • Ages 24 to 120 hours
  • All sexes
  • Healthy volunteers accepted

Study population: The study population will be a convenience sample, comprised of singleton neonates born at or after 35 weeks post-menstrual age at the University of Rochester Medical Center (URMC). Cases will be infants of mothers with either a diagnoses of pre-gestational diabetes or gestational diabetes whose provider recommends treatment with insulin or oral glycemic agents. Controls will be neonates whose mothers had normal glucose testing during gestation and pre-pregnancy BMI of <30. All subjects will be otherwise healthy, as defined by the exclusion criteria. There is no intended racial, ethnic or gender distribution of these neonates.

Who may be able to join

  • >/= 35 weeks post-menstrual age at delivery
  • Dating by, or consistent with, 1st trimester ultrasound
  • Mother able to communicate in oral and written English

About this study

Alterations in the intrauterine environment can have profound effects on fetal development. Diabetes during gestation results in multiple deleterious short-term outcome differences, and is correlated with long-term developmental deficits. Multiple studies, in neonates through school-aged children, have demonstrated differences in language, attention and psychomotor development in offspring of diabetic pregnancies. Neonatal EEG is a promising and non-invasive tool for assessment of abnormal brain development or "dysmaturity" in this population. Multiple conventional EEG (cEEG) and amplitude-integrated EEG (aEEG) parameters change predictably with advancing gestational development and have been used to differentiate between at risk groups in neonatal studies.

The investigators hypothesize that neonatal EEG can identify brain dysmaturity in infants of diabetic mothers (IDMs) compared to gestational-age matched controls. The primary aim is documentation of brain dysmaturity in IDMs using cEEG. The secondary aim is establishment of aEEG as a more accessible tool to quantify the effects of maternal diabetes on neonatal brain development.

The investigators will conduct a pilot study comparing cEEG and aEEG parameters of cases to gestational-age matched controls. Cases will be IDM neonates of at least 35 weeks' gestation whose mothers were recommended treatment with either insulin or an oral glycemic agent. Video EEG recording will be planned for approximately 60 minutes and obtained between 24 hours and 5 days of life during birth hospitalization. Additional data will be extracted from maternal and neonatal medical records and a maternal questionnaire.

In addition to evaluating the measures of cEEG and aEEG, this project will establish a research cohort. A subsequent study involving developmental evaluations will allow for correlation of EEG results with long-term outcomes. The ability to identify those at risk at birth would provide the opportunity to intervene in order to mitigate outcome differences, particularly in language development. More significantly, we hope to establish neonatal CNS outcome measures for future diabetic pregnancy intervention studies. .

  • Point-of Care Blood Sugar TestingOther

    One-time heel-stick point-of-care blood sugar testing at time of EEG.

  • Medical Record Data ExtractionOther

    Medical record data extraction from both maternal obstetric and neonatal medical record for variables known to impact EEG and neurodevelopmental outcomes.

  • Maternal QuestionnaireOther

    One-time maternal questionnaire related to smoking practices, ETOH consumption, level of education, and body mass index.

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes in Pregnancy and Diabetes, Gestational, run by University of Rochester at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum Interburst Interval on cEEG (time frame: Single EEG between 24 hours of life and 5 days of life). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2020.
