Impaired High-Density Lipoprotein Function in Patients With Heart Failure.

J Am Heart Assoc 2021 Apr 17:e019123. Epub 2021 Apr 17.

Department of Pediatrics University of Groningen Groningen The Netherlands.

Background We recently showed that, in patients with heart failure, lower high-density lipoprotein (HDL) cholesterol concentration was a strong predictor of death or hospitalization for heart failure. In a follow-up study, we suggested that this association could be partly explained by HDL proteome composition. However, whether the emerging concept of HDL function contributes to the prognosis of patients with heart failure has not been addressed. Read More

Cytotoxic T-lymphocyte infiltration and chemokine predict long-term patient survival independently of tumor mutational burden in triple-negative breast cancer.

Ther Adv Med Oncol 2021 5;13:17588359211006680. Epub 2021 Apr 5.

Breast Surgery, Department of Surgical Oncology, Roswell Park Comprehensive Cancer Center, Elm & Carlton Streets, Buffalo, NY 14263, USA.

Background: Cytotoxic T-lymphocyte (CTL) infiltration into tumor is a positive prognostic factor in breast cancer. High tumor mutational burden (TMB) is also considered as a predictor of tumor immunogenicity and response to immunotherapy. However, it is unclear whether the infiltration of functional CTL simply reflects the TMB or represents an independent prognostic value. Read More
