Bone Marrow Sampling and Transplants01:22

Bone Marrow Sampling and Transplants

858
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Stem Cell Therapy for Tissue Regeneration

4.6K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Heart Failure Drugs: Inotropic Agents

1.2K
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...

Area of Science:

  • Pediatric Cardiology
  • Oncology
  • Critical Care Medicine

Background:

  • Cancer therapy-related cardiac dysfunction is a critical, often under-recognized issue in pediatric hemato-oncology.
  • Levosimendan is explored for its cardio-protective potential in pediatric onco-critical care.

Purpose of the Study:

  • To assess the efficacy and safety of levosimendan in pediatric patients with cardiac dysfunction undergoing chemotherapy or HSCT.
  • To evaluate levosimendan's effectiveness as a first- and second-line cardiac support agent.

Main Methods:

  • Retrospective study of 62 children (up to 18 years) from January 2020 to December 2023.
  • Levosimendan administered as first-line for known dysfunction and second-line for shock with dysfunction.
  • Efficacy assessed via ejection fraction, Vasoactive-Inotropic Score (VIS), and echocardiography (ECHO).

Main Results:

  • 85% overall response rate observed in pediatric patients.
  • Mean ejection fraction improved from 50% to 58%.
  • Mean VIS reduction of 3.2; normal heart function on follow-up ECHO at four weeks.

Conclusions:

  • Levosimendan is a safe and effective treatment for acute heart failure in pediatric hemato-oncology patients with preserved blood pressure.
  • Results aid in tailoring critical care for pediatric hemato-oncology patients experiencing cardiac dysfunction.
