SACHA-France (NCT04477681) is a prospective real-world study that collects clinical safety and efficacy data of novel anticancer therapies prescribed off-label or on compassionate use to patients <25 years. From March 2020 until February 2024, 640 patients with solid tumors or lymphomas were included, with 176 (28%) reported objective tumor responses. Centralized medical monitoring of local radiological/functional imaging reports by the SACHA coordinating investigator led to response modification in 45 out of 176 cases (26%), highlighting the relevance of the medical review of study data. We suggest this pragmatic approach for improving clinical trial data when centralized radiological review is not performed.

Pyruvate kinase (PK) activation is emerging as a promising treatment modality for numerous congenital hemolytic anemias of diverse pathophysiology, and one agent, mitapivat, is already licensed to treat patients with congenital PK deficiency. However, PK deficiency may also be acquired in the setting of clonal myeloid disorders and other pathologies, where it may result in severe hemolytic anemia and remains without known therapies. This case report describes the novel application of mitapivat therapy in a patient with acquired PK deficiency causing red cell transfusion dependence, liberating the patient from transfusions and resulting in marked improvement in symptoms and quality of life.

Childhood cancer survivors (CCS) frequently experience cognitive challenges, which impact their ability to participate in functional activities. This systematic review examines the effects of nonpharmacological cognitive interventions on functional outcomes (e.g., activities of daily living). We systematically searched eight databases (e.g., PubMed, EMBASE) from 2012 to 2023. Two team members independently screened articles and extracted article, intervention, sample characteristics, and outcome data. We assessed intervention reporting with the Template for Intervention Description and Replication. Fourteen studies met inclusion criteria, representing 12 unique trials. Four of the six trials evaluating Cogmed, a computerized working memory training program, demonstrated functional benefits; small to large effects were observed for academic achievement (Cohen's d = 0.28-0.87) and decreased inattention in daily life (d = -0.36 and -0.98). Other interventions included exergaming, math or reading interventions, occupational therapy, and neurofeedback. Less than half of studies reported on intervention personalization (n = 5), fidelity assessment (n = 4), or cost (n = 1). Study heterogeneity limited our ability to meta-analyze results for functional outcomes. Limited evidence and gaps in quality of intervention reporting are barriers to addressing the cognitive challenges of CCS. Standardizing functional outcome measurement, identifying effective interventions, and improving the quality of intervention reporting could accelerate the translation of intervention research to clinical practice.

Background: The gift of postmortem tissue donation is critical to pediatric central nervous system (CNS) research. As a "Center of Excellence" for the Gift from a Child Program, our institution has a well-established postmortem tissue donation program. Our objective was to determine if differences exist between patients who participated in and those that declined research-based autopsy.

Procedure: We performed a single-institution retrospective chart review of pediatric patients with CNS malignancies who died from their disease between January 1, 2021 and December 31, 2022. Individual clinical, demographic, and socioeconomic data were assessed. Population-level data were estimated using Zip Code Tabulation Areas. Descriptive statistics were used to compare categorical data.

Results: Among the 23 patient families approached during the study time frame, 8/23 (35%) consented to participation. In the consented (C) versus declined (D) group, there was a higher percentage of White, non-Hispanic/Latino patients by self-reported race (C: 88% vs. D: 55%), and no patients who identified as Asian or Hispanic/Latino (C: 0% and 0% vs. D: 13% and 27%). Of all patients approached, two required interpreters (9%), and both families declined participation. The rate of private insurance was higher in the consented group (C: 75% vs. D: 47%) compared to Medicaid as primary insurance in the declined group (C: 13% vs. D: 53%).  CONCLUSIONS: Future research should aim to understand and improve identified disparities to ensure research advancements benefit all children with CNS malignancies. One area we plan to address is improved communication with non-English-speaking families by partnering with our interpreter services.

Athletes are at high risk of iron deficiency even without anemia. In this systematic review and meta-analysis that included 17,519 athletes in 122 references from 23 countries, participating in 62 unique sports over a 41-year timeframe, approximately 53.9% of student-athletes were found to be hypoferritinemic (ferritin concentration below 50 mcg/L) with 23.0% percent showing absolute iron deficiency based on current definitions (ferritin concentration below 20 mcg/L). These findings strongly suggest that changes in clinical practice guidelines are warranted to enable routine screening for iron deficiency among adolescent and collegiate athletes.
