BACKGROUND Transfer of care from pediatric to adult-oriented providers is challenging for adolescents with sickle cell disease (SCD). The need for transition programs is known, however many SCD patients leave pediatric care without adequate preparation. This study has two aims: to assess adolescent SCD patients' preparation for transition and to identify(More)
BACKGROUND Alloimmunization to minor red blood cell (RBC) antigens occurs commonly in sickle cell disease (SCD). Patients with alloimmunization demonstrate increased risk for new alloantibody formation with subsequent transfusion. Alloimmunization to human leukocyte antigens (HLA) can occur with RBC transfusion and may result in graft rejection during stem(More)
S-nitrosoglutathione (GSNO), a naturally occurring constituent of airway lining fluid, enhances ciliary motility, relaxes airway smooth muscle, inhibits airway epithelial amiloride-sensitive sodium transport, and prevents pathogen replication. Remarkably, airway levels of GSNO are low in patients with cystic fibrosis (CF). We hypothesized that replacement(More)
Busulfan influences engraftment and toxicities during hematopoietic stem cell transplantation (HSCT). We report our single-institution experience of targeted busulfan therapy for myeloablative, matched sibling donor (MSD) HSCT for sickle cell disease (SCD) and assess the relationships of busulfan levels to engraftment and toxicities. Twenty-seven patients(More)
BACKGROUND Sickle cell disease (SCD) patients have unique transfusion considerations during bone marrow transplantation (BMT), including prophylaxis against stroke and alloimmunization. Characterization of transfusion requirements is important for blood bank and clinician patient management. STUDY DESIGN AND METHODS A retrospective analysis of red blood(More)
Intensive efforts are underway across the world to improve the quality of health care. It is important to use evaluation methods to identify improvement efforts that work well before they are replicated across a broad range of contexts. Evaluation methods need to provide an understanding of why an improvement initiative has or has not worked and how it can(More)
Care and outcomes for individuals living with sickle cell disease (SCD) vary across institutions and communities. The Hemoglobinopathy Learning Collaborative (HLC) seeks to improve outcomes across the life course through improvement science. Faculty identified five key drivers of improved outcomes: a strong community network; knowledgeable, proactive(More)
Promoting healthy weight requires innovative approaches and a concerted response across all sectors of society. This commentary features the framework guiding the Healthy Weight Collaborative, a two-phased quality improvement (QI) learning collaborative and key activity of the Collaborate for Healthy Weight initiative. Multi-sector teams from primary care,(More)
Policies at many levels may help to shape environments that promote healthy weight and prevent obesity. We present policies to support obesity prevention for young children. We highlight policy Sand environmental systems change examples in the areas of promoting breastfeeding and providing healthy affordable food and information about food in community and(More)
