Financial distress and medical financial hardship among young adult survivors of blood cancer.

Background: The long-term financial impact of cancer care has not been adequately addressed in young adults. As part of a remote intervention study, we describe medical financial distress and hardship among young adult survivors of blood cancer at study entry.

Methods: Young adults were recruited from 6 US hospitals.

Transient Stress Lymphocytosis in a Child: A Case Report and Systematic Review of the Literature.

Transient stress lymphocytosis (TSL) is an under-recognized phenomenon associated with an acute stressful event such as physical trauma or various emergency medical conditions. Lymphocytosis generally resolves within several hours to days of the stressor. While most reports of TSL predominantly involve adult patients, it has only rarely been reported in pediatric patients.

A Novel Discriminating Tool for Microcytic Anemia in Childhood.

Accurate and timely interpretation of microcytic anemia can be diagnostically challenging in the primary care setting. We sought to develop a novel model for distinguishing iron-deficiency anemia from thalassemia trait in the modern pediatric population. Demographic history and red blood cell indices were retrospectively characterized for 76 children referred to our pediatric hematology clinic for evaluation of microcytic anemia.

Hispanic/Latinos and non-Hispanic whites' childhood cancer survivors and parents: a dyadic analysis of coping resources and mental health.

Purpose: While limited, dyadic research demonstrates the interdependent relationship between the health and adjustment after treatment between cancer survivors and caregivers. We examined interrelationships between coping resources and mental health among childhood cancer survivors (CCS)-parent dyads.

Methods: One hundred sixty CCS-parent dyads from the Project Forward pilot study completed validated questions assessing social support, religiosity, spirituality, depressive symptoms, and perceived stress.

Barriers and facilitators of Hispanic/Latino parents caregiving for a childhood cancer survivor: a qualitative study.

Purpose: This qualitative study aimed to explore Hispanic parents of childhood cancer survivors (CCS) perceptions of facilitators and barriers to their caregiving experience.

Methods: We conducted semi-structured phone interviews with 15 Hispanic/Latino parents (English and Spanish). Parents were recruited using a purposive sampling method in a safety-net hospital in Los Angeles County from July-September 2020.

Understanding Delayed Presentation to Emergency Care in Pediatric Patients With Neutropenic Fever.

We investigated social and logistic factors eg, distance from the medical center, language barriers, other children to care for, number of caregivers, etc.) for families to delay seeking immediate emergency care for neutropenic fever in a retrospective cohort study of all pediatric hematology-oncology patients who presented for fever in the setting of neutropenia to our emergency department or clinic from 2015 to 2020. Patients with a history of at least 2 prior admissions for neutropenic fever waited more often for a second fever before presenting versus those without such history (odds ratio 5.

The Impact of Hispanic Ethnicity and Language on Communication Among Young Adult Childhood Cancer Survivors, Parents, and Medical Providers and Cancer-Related Follow-Up Care.

Purpose: The triad of communication between young adult childhood cancer survivors (YACCSs), their parents, and their medical providers is an important process in managing health care engagement. This study sought to identify communication patterns among this triad, factors associated with communication, and engagement of survivorship care.

Methods: We analyzed data from Project Forward, a population-based study that surveyed YACCSs and their parents.

Survival of pediatric Hodgkin lymphoma patients treated with doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (ABVE-PC) versus doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) at a single institution.

Background: Adriamycin, bleomycin, vinblastine, dacarbazine (ABVD), the de facto standard of care in adult-onset Hodgkin lymphoma (HL), has not been directly compared to doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (ABVE-PC), a pediatric-aimed regimen designed to reduce late effects. We aimed to describe the single-institution experience of using both regimens in patients with pediatric HL.

Methods: This retrospective cohort study evaluated a total of 224 patients diagnosed with HL between 1999 and 2018 at Children's Hospital Los Angeles (CHLA), of which 93 patients were eligible having received ABVD (n = 46) or ABVE-PC (n = 47) chemotherapy as their initial treatment.

Effect of childhood obesity on admissions for respiratory disease.

Aim: The purpose of this study was to assess for an association between higher body mass index and disease severity, morbidity and mortality in children admitted for an acute respiratory distress and failure.

Methods: A single-institution retrospective cross-sectional study performed in the United States evaluating paediatric patients, 2-20 years of age, admitted for diagnoses related to acute respiratory distress and acute respiratory failure. Main outcomes include disease severity as assessed using the respiratory component of the Paediatric Early Warning Score (PEWS) with adjustment for altered mental status (Resp-PEWS + AMS), hospital or intensive care length of stay (LOS) and death.

Post-Chemotherapy Histiocyte-Rich Pseudotumors: Radiologic and Endoscopic Mimics of Residual Lymphoma.

Development of post-chemotherapy histiocyte-rich pseudotumor (PHP) is an underrecognized event following therapy in lymphoma patients and may mimic residual tumor using current therapy monitoring protocols. We report a series of 5 patients with PHP along with a review of the literature. In our series, we describe 3 patients with persistent hypermetabolic masses by positron emission tomography-computed tomography, one with persistent terminal ileal nodules on endoscopy, and one with bone marrow involvement, a site not associated with mass-like disease.

Combined immune checkpoint blockade increases CD8+CD28+PD-1+ effector T cells and provides a therapeutic strategy for patients with neuroblastoma.

Immune checkpoint therapy has resulted in minimal clinical response in many pediatric cancers. We sought to understand the influence of immune checkpoint inhibition using anti-PD-1 and anti-CTLA-4 antibodies individually, in combination, and after chemotherapy on immune responses in minimal and established murine neuroblastoma models. We also sought to understand the role of the tumor microenvironment (TME) and PD-L1 expression and their alteration post-chemotherapy in our models and human tissues.

Multidrug Therapy for Refractory Immune Thrombocytopenia in Pregnancy.

Background: Severe immune thrombocytopenia complicating pregnancy may require treatment beyond first-line medications (intravenous immunoglobulins or corticosteroids), but there is a paucity of literature on the use of such second-line agents in pregnancy.

Case: The patient is a 29-year-old woman with early-onset severe immune thrombocytopenia at 13 weeks of gestation. Maternal platelet counts reached a nadir of less than 5×10/L.

Tumor-associated macrophages promote neuroblastoma via STAT3 phosphorylation and up-regulation of c-MYC.

Tumor-associated macrophages (TAMs) are strongly associated with poor survival in neuroblastomas that lack amplification. To study TAM action in neuroblastomas, we used a novel murine model of spontaneous neuroblastoma lacking amplification, and observed recruitment and polarization of TAMs, which in turn enhanced neuroblastoma proliferation and growth. In both murine and human neuroblastoma cells, we found that TAMs increased STAT3 activation in neuroblastoma cells and transcriptionally up-regulated the oncogene.

Hyperglycemic Hyperosmolar State During Induction Chemotherapy for Acute Lymphoblastic Leukemia.

We present the case of a 16-year-old boy who presented with fatigue, polyuria, and polydipsia while on chemotherapy for his relapsed acute lymphoblastic leukemia (ALL). Blood gas examination confirmed the diagnosis of hyperosmolar hyperglycemic state. The etiology for his hyperglycemia was most likely a result of oral glucocorticoid therapy combined with asparaginase therapy-both are a cornerstone of induction chemotherapy for ALL.
