Palbociclib Is Safe for Breast Cancer Patients With Mild Hepatic Impairment: A Multicenter Retrospective Study Using Real-World Data.

The liver is crucial for metabolizing the anticancer drug palbociclib, but limited information is available on the impact of hepatic impairment on its toxicity and efficacy, with no real-world data available. This study aims to evaluate how hepatic impairment affects hematological toxicity and progression-free survival (PFS) of palbociclib in advanced hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer, using the National Cancer Institute scoring system, in a large real-world dataset. This multicenter retrospective observational study included female patients treated with palbociclib between August 2017 and February 2024.

Longevity of antibody responses is associated with distinct antigen-specific B cell subsets early after infection.

Introduction: Upon infection, T cell-driven B cell responses in GC reactions induce memory B cells and antibody-secreting cells that secrete protective antibodies. How formation of specifically long-lived plasma cells is regulated via the interplay between specific B and CD4+ T cells is not well understood. Generally, antibody levels decline over time after clearance of the primary infection.

Feasibility of a new transmural care pathway for advance care planning for older persons: A qualitative study into community care registered nurses' perspectives.

Background: Transmural palliative care interventions aim to identify older persons with palliative care needs and timely provide advance care planning, symptom management, and coordination of care. Nurses can have an important role in these interventions; however, their expertise is currently underused. A new transmural care pathway with a central role for the community care registered nurse in advance care planning aims to contribute to the quality of palliative care for older persons.

Adolescent urinary concentrations of phthalate metabolites and indices of overweight and cardiovascular risk in Dutch adolescents.

Phthalates have been linked to cardiovascular risk factors. Exposure to chemicals with endocrine disrupting properties during the pubertal period can interfere with normal endocrine processes. This study aims to determine whether adolescent urinary concentrations of phthalate metabolites are associated with indices of overweight and cardiovascular risk in 13-15-year-old children.
