Pembrolizumab-induced nephrotoxicity in a patient with breast cancer.

The introduction of immunotherapy has revolutionized the treatment and improved outcomes of multiple types of cancer. Although breast cancer is a less immune-responsive tumor type, the incorporation of pembrolizumab into chemotherapy regimens in the neoadjuvant and first-line metastatic setting for the triple-negative disease has improved outcomes. However, the use of this type of treatment is associated with a spectrum of adverse events.

Oncotype DX Recurrence Score in premenopausal women.

In the past 20 years, clinicians have shifted away from relying solely on clinicopathologic indicators toward increasing use of multigene expression assays in guiding treatment decisions regarding adjuvant chemotherapy for early-stage hormone receptor (HR)-positive, HER2-negative breast cancer. Oncotype DX Recurrence Score (RS) is one of the most widely used multigene assays when considering indications for adjuvant chemotherapy, and guidelines have recently incorporated its use in women with early HR-positive HER2-negative breast cancer and up to three positive lymph nodes. While multiple retrospective and prospective clinical studies have demonstrated that most women with a low- to mid-range RS (0-25) can safely forgo chemotherapy, premenopausal women remain an important subgroup for which recommendations based on RS are ill-defined.

Antimalarial activity of 2,6-dibenzylidenecyclohexanone derivatives.

Malaria remains one of the deadliest infectious diseases worldwide and continues to infect hundreds of millions of individuals each year. Here we report the discovery and derivatization of a series of 2,6-dibenzylidenecyclohexanones targeting the chloroquine-sensitive 3D7 strain of Plasmodium falciparum . While the initial lead compound displayed significant toxicity in a human cell proliferation assay, we were able to identify a derivative with no detectable toxicity and sub-micromolar potency.
