Language, Culture, and Cancer: Qualitative Insights Into Communication Disparities Among Spanish‐Speaking Caregivers of Children With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Latino children are projected to make up nearly one‐third of United States (US) children by 2060, and many of their caregivers speak Spanish. Prior survey research has documented communication difficulties for Spanish‐speaking caregivers of children with cancer, but contemporary qualitative data are limited.

Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

Classical Complement Pathway Inhibition in a Pediatric Patient With Refractory Immune Thrombocytopenia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric refractory immune thrombocytopenia (rITP) is generally characterized by persistent thrombocytopenia and failure to achieve a sustained response to multiple standard therapies. We report a 4‐year‐old female with congenital tufting enteropathy, post‐intestinal transplant patient on immunosuppressants, who developed severe rITP ...
