The role of donor type and pre-transplant immunosuppression on outcomes of hematopoietic stem cell transplantation in children and young adults with severe aplastic anemia.

Background: The goal of this study was to assess the effect of donor type and pre-transplant immunotherapy (IST) on outcomes of hematopoietic stem cell transplantation (HSCT) for children and young adults with severe aplastic anemia (SAA).

Methods: This retrospective, multi-center study included 52 SAA patients, treated in 5 pediatric transplant programs in Florida, who received HSCT between 2010 and 2020 as the first- or second-line treatment.

Results: The median age at HSCT for all 52 patients was 15 years (range 1-25).

Statewide Hospital Admissions for Adult Survivors of Infant Surgical Diseases Over a 10-Year Period.

Introduction: The number of patients with congenital disease living to adulthood continues to grow. Often undergoing surgical correction in infancy, they continue to require lifelong care. Their numbers are largely unknown.

Azithromycin for Pediatric Critical Asthma: A Multicenter Retrospective Cohort Study.

Objectives: To characterize the prescribing trends and clinical outcomes related to azithromycin (AZI) among children hospitalized for critical asthma (CA).

Methods: We performed a multicenter, retrospective cohort study using the Pediatric Health Information Systems registry of children 3 to 17 years of age hospitalized in a PICU for CA from January 2011 to December 2022. We excluded for alternative indications for AZI (eg, atypical pneumonia, B.

Concurrent cecal lipoma and Crohn's disease in a pediatric patient: A conservative approach.

We report the case of a 14-year-old patient with a known history of Crohn's disease who was incidentally diagnosed with an asymptomatic cecal lipoma. A routine surveillance colonoscopy as part of the management of the patient's Crohn's Disease revealed a well-defined, submucosal, yellowish mass in the patient's cecum. Histopathological examination of a biopsy specimen revealed submucosal adipose tissue, consistent with the endoscopic images showing the characteristic appearance of the lipoma.

Infant out-of-hospital cardiac arrest during nights and weekends.

Background: A growing body of evidence suggests outcomes for cardiac arrest in adults are worse during nights and weekends when compared with daytime and weekdays. Similar research has not yet been carried out in the infant setting.

Methods: We examined the National Emergency Medical Services Information System (NEMSIS), a database containing millions of emergency medical services (EMS) runs in the United States.

Training Law Enforcement Officers About Autism: Evaluation of Adding Virtual Reality or Simulation to a Traditional Training Approach.

Prevalence rates of autism spectrum disorder (ASD) across the globe and lifespan suggest that law enforcement officers (LEOs) are likely to interact with autistic people in their professional duties. In developed countries, LEOs have professional encounters with autistic individuals, and research strongly supports LEOs need training to increase their knowledge about autism and confidence interacting with autistic people. The purpose of the present study is to compare three training approaches with LEOs: (a) a training presentation alone (P), (b) a training presentation combined with virtual reality simulation (P + VR), and (c) a training presentation combined with in-vivo simulation (P + SIM).

Association of limited dorsal myeloschizis and corpus callosum lipoma: A case report and literature review.

Background: Intracranial lipomas are a rare clinical entity. These lesions are frequently asymptomatic and originate in the pericallosal area. As they are fat-containing lesions which are intimately attached to the surrounding structures, surgery is not recommended.

Extracardiac Manifestations Fail to Predict the Severity of Cardiac Phenotype in Children and Young Adults with Marfan Syndrome.

We performed a secondary analysis of the Pediatric Heart Network (PHN) Marfan Trial public-use database to evaluate associations between extracardiac features and cardiac and aortic phenotypes in study participants. Aortic aneurysm phenotype was defined as aortic root Z-score ≥4.5, aortic root growth rate ≥75th percentile, aortic dissection, and aortic surgery.

Vitamin K Prescribing Trends Among Critically Ill Children Hospitalized for Sepsis: A Multicenter Observational Cohort Study.

Vitamin K (VK) is commonly prescribed for pediatric sepsis-induced coagulopathy without trial-derived evidence to support its use for this indication. The purpose of this study was to characterize national prescribing trends for VK in this population. This is a multicenter retrospective cohort study using the Pediatric Health Information System registry including children 0 to 17 years of age hospitalized for sepsis in the pediatric intensive care unit from January 2016 through December 2022.

Timing of Red Blood Cell Transfusions and Occurrence of Necrotizing Enterocolitis: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Observational studies often report that anemia and red blood cell (RBC) transfusions are associated with a higher risk of necrotizing enterocolitis (NEC) among extremely low-birthweight (ELBW) infants.

Objective: To evaluate whether there is a temporal association between 72-hour hazard periods of exposure to RBC transfusions and NEC among ELBW infants randomized to either higher or lower hemoglobin transfusion thresholds.

Design, Setting, And Participants: This post hoc secondary analysis of 1690 ELBW infants who survived to postnatal day 10 enrolled in the Transfusion of Prematures (TOP) randomized multicenter trial between December 1, 2012, and April 12, 2017, was performed between June 2021 and July 2023.

Cognitive Outcomes of Children With Sagittal Craniosynostosis Treated With Either Endoscopic or Open Calvarial Vault Surgery.

Importance: Several studies have reported a higher incidence of neurodevelopmental delays and cognitive deficits in patients with single-suture craniosynostosis; however, there are few studies examining the associations of repair type with cognitive outcomes.

Objective: To measure differences in neuropsychological outcomes between school-age children who were treated for sagittal craniosynostosis and unaffected controls and explore differences in cognitive function among children with sagittal craniosynostosis who were previously treated with either endoscopic strip craniectomy or open calvarial vault surgery.

Design, Setting, And Participants: This cohort study was performed between 2018 and 2022.

The interplay of psychosis and non-compliance with fatal outcome in an adult with MSUD.

Significant progress has been achieved in enhancing early outcomes for individuals with maple syrup urine disease (MSUD), a rare metabolic disorder that leads to the accumulation of branched-chain amino acids leucine, isoleucine, and valine, where leucine is known as the primary neurotoxic metabolite. Newborn screening is helpful in early diagnosis and implementation of dietary treatment, thus reducing neurological deterioration and complications in young children. However, patients face the life-long challenge of maintaining metabolic control through adherence to a strict low-leucine diet to avoid long-term consequences of chronic hyperleucinemia, which include cognitive deficits, mood disorders, and movement disorders.

Promoting penicillin allergy de-labeling for children attending a hematology clinic.

Background: Up to 10% of children are reported to be allergic to penicillin, but many allergy labels are unverified and may require formal testing. Inaccurate drug allergy labels are associated with a range of adverse clinical outcomes. Patients with hematological disorders may experience frequent and severe infections; those who have been incorrectly labeled penicillin allergic may benefit from allergy de-labeling (ADL) efforts to facilitate access to beta-lactam antibiotics.

Ketorolac Dosing and Outcomes in Neonates Following Congenital Heart Surgery: A Retrospective Analysis.

Background: Pain management is essential for postoperative surgery. Given the association of opioids with adverse outcomes, interest in the use of nonopioid analgesics, such as ketorolac, has increased. Published data on use in neonates are limited.

Revisiting the anatomy of the left ventricle in the light of knowledge of its development.

Despite centuries of investigation, certain aspects of left ventricular anatomy remain either controversial or uncertain. We make no claims to have resolved these issues, but our review, based on our current knowledge of development, hopefully identifies the issues requiring further investigation. When first formed, the left ventricle had only inlet and apical components.

Event-free survival in relapsed and refractory rhabdomyosarcoma treated on cooperative group phase II trials: A report from the Children's Oncology Group.

Background: Novel therapies are needed for relapsed and refractory rhabdomyosarcoma (RRMS). Phase II clinical trials in RRMS have typically utilized radiologic response as the primary activity endpoint, an approach that poses several limitations in RRMS. In this analysis, we aimed to estimate an event-free survival (EFS) endpoint for RRMS that could be used as a benchmark for future studies.

Massive Transfusion in Pediatric Patients on Extracorporeal Membrane Oxygenation: A Secondary Analysis of the Massive Transfusion in Children (MATIC) Study.

Few data describe pediatric patients who receive massive transfusion for life-threatening hemorrhage (LTH) while on extracorporeal membrane oxygenation (ECMO). We present a retrospective secondary analysis of a multicenter prospective observational study to describe resource utilization and mortality in pediatric patients with LTH while on ECMO. Children who were on ECMO during an LTH were compared to children with LTH who were not on ECMO.
