Chimeric antigen receptor T cell (CAR-T) therapy involves reengineering patient-derived or donor-derived T cells to express a synthetic CAR that can recognise specific cell-surface antigens, independently of major histocompatibility complex molecules. As of March 2025, six autologous CAR-T cell products have received regulatory approval from the United States Food and Drug Administration (FDA) for B-cell derived haematological malignancies and multiple myeloma, delivering effective and durable treatment responses. All currently approved CAR-T cell therapy products target either CD19 or B-cell maturation antigen (BCMA).

Immune effector cell-associated neurotoxicity syndrome (ICANS)-associated cognitive impairment is common in patients who receive chimeric antigen receptor T-cell (CAR-T) therapy. This study evaluated the utility of the clock drawing task (CDT) in detecting ICANS in patients with haematological cancers following CAR-T therapy. Data were collected from CAR-T patients at The Alfred Hospital, Melbourne, Australia.

Background: Immune effector cell-associated neurotoxicity syndrome (ICANS) is a common complication of chimeric antigen receptor (CAR) T-cell therapy. Current practice guidelines recommend the immune effector cell-associated encephalopathy (ICE) score for the assessment and monitoring of ICANS.

Objective: To demonstrate modifications to ICE score to patients with vision and hearing impairments or who are who are from non-native-speaking backgrounds.

Gaps in knowledge remain related to understanding missed human immunodeficiency virus (HIV) visits and youth with HIV (YWH). This study examined data from an Alabama academic HIV clinic with clients aged 16 to 24 years old and found that non virally suppressed and older YWH were associated with missed visits among YWH.

Purpose: Adolescents are disproportionately burdened with HIV. Numerous barriers limit adolescent pre-exposure prophylaxis (PrEP) use for HIV prevention. We explored adolescent-caregiver perspectives on discussing sexual health and PrEP to inform future caregiver interventions as a possible strategy to promote PrEP use.
