Real-World Application of Recently Proposed ASTCT/CIBMTR/EBMT/APBMT Consensus Risk Stratification for Transplantation-Associated Thrombotic Microangiopathy in Children.

Consensus diagnostic and risk stratification of transplantation-associated thrombotic microangiopathy (TA-TMA) was recently achieved from international transplantation groups. Although the proposed diagnostic criteria have been applied to multiple pediatric cohorts, there are scant data applying the novel risk stratification approach in children with TA-TMA. In this retrospective cohort study, all children undergoing an allogeneic HCT or autologous HCT for neuroblastoma were prospectively screened for TA-TMA, diagnosed, and risk-stratified using the Jodele criteria from August 2019 to October 2023.

D-dimer and sinusoidal obstructive syndrome-novel poor prognostic features of thrombotic microangiopathy in children after hematopoietic cellular therapy in a single institution prospective cohort study.

Transplant-associated thrombotic microangiopathy (TA-TMA) is a common, severe complication of allogeneic hematopoietic cellular therapy (HCT). Even when treated in many studies, morbidity and mortality rates are high. This prospective single-institution cohort study serially enrolled all allogeneic HCT recipients from August 2019-August 2022.

BCMA CAR-T induces complete and durable remission in refractory plasmablastic lymphoma.

Plasmablastic lymphoma (PBL) is a rare subtype of aggressive large B-cell lymphoma, with a dismal prognosis despite aggressive therapies. New approaches are needed for those with refractory disease. PBL expresses antigens similar to multiple myeloma (MM), including B-cell maturation antigen (BCMA).

Fertility Preservation Practices at Pediatric Oncology Institutions in the United States: A Report From the Children's Oncology Group.

Purpose: Fertility discussions are an integral part of comprehensive care for pediatric, adolescent, and young adult patients newly diagnosed with cancer and are supported by national guidelines. Current institutional practices are poorly understood.

Methods: A cross-sectional survey was distributed to 220 Children's Oncology Group member institutions regarding fertility discussion practices.

Nutritional Support: Enteral Nutrition Pathway for Children Undergoing Hematopoietic Stem Cell Transplantation.

Background:  Children undergoing a hematopoietic stem cell transplantation (HSCT) are at a higher risk for malnutrition, which could be reduced by enteral nutrition (EN) support.

Objectives:  This study evaluated the safety and feasibility of implementing an EN pathway for children undergoing HSCT.

Methods:  An evidence-based, standardized EN pathway was implemented for children undergoing HSCT.

Comparison of Anti-Mullerian Hormone Levels Pre- and Post-Hematopoietic Cell Transplantation in Pediatric and Adolescent Females with Sickle Cell Disease.

Allogeneic hematopoietic cell therapy (HCT) is an established cure for sickle cell disease (SCD); however, HCT conditioning regimens are known to be gonadotoxic. Anti-mullerian hormone (AMH) measures ovarian reserve, and follicle-stimulating hormone (FSH) defines premature ovarian insufficiency (POI) at values >40 mIU/mL in pubertal females. The present study was conducted to assess ovarian reserve and function before and after transplantation in pediatric and adolescent females with SCD treated with allogeneic HCT between January 2015 and June 2020 at Children's Healthcare of Atlanta.

Mismatched Unrelated Donor Hematopoietic Stem Cell Transplantation Rescues Marrow Failure From Acute Leukemia Therapy in a Patient With Previously Undiagnosed Ligase IV Syndrome.

Patients with DNA double-strand breakage repair disorders are at increased risk of malignancy which is often difficult to treat given underlying sensitivity to chemotherapy and radiotherapy, lending an important role to hematopoietic stem cell transplantation. The choice of conditioning regimen used must balance reducing risk of rejection with minimizing excessive toxicity from myeloablative chemotherapy or ionizing radiation. We describe successful engraftment following a nonmyeloablative hematopoietic stem cell transplantation in a patient with Ligase IV syndrome and numerous pretransplant complications including malignancy, cardiac failure, and secondary hemophagocytic lymphohistiocytosis.

Infrastructure of Fertility Preservation Services for Pediatric Cancer Patients: A Report From the Children's Oncology Group.

Purpose: Fertility preservation (FP) services are part of comprehensive care for those newly diagnosed with cancer. The capacity to offer these services to children and adolescents with cancer is unknown.

Methods: A cross-sectional survey was sent to 220 Children's Oncology Group member institutions regarding institutional characteristics, structure and organization of FP services, and barriers to FP.
