Racial disparities in timing and outcomes for patients undergoing staged single ventricle palliation: a single institution report.

Background: Racial disparities in healthcare have been well documented in the United States. We hypothesise that there will be a racial variance in different clinical variables in single-ventricle patients through stages of palliation.

Materials And Methods: Retrospective single-centre study stratified all single-ventricle patients who reached stage 2 palliation by race: Black and White.

Impact of Antegrade Pulmonary Blood Flow as Patients Progress Through Single-Ventricle Palliations.

Background: The impact of antegrade pulmonary blood flow (APBF) during single-ventricle (SV) palliation continues to be debated. We sought to assess its impact on the hemodynamic profile and the short- and long-term outcomes of patients progressing through stages of SV palliation.

Methods: A retrospective single-center study was conducted of SV patients who underwent surgery between January 2010 and December 2020.

G-protein signaling is required for increasing germline stem cell division frequency in response to mating in Drosophila males.

Adult stem cells divide to renew the stem cell pool and replenish specialized cells that are lost due to death or usage. However, little is known about the mechanisms regulating how stem cells adjust to a demand for specialized cells. A failure of the stem cells to respond to this demand can have serious consequences, such as tissue loss, or prolonged recovery post injury.
