Unlabelled: T cells are generally sparse in hormone receptor-positive (HR+) breast cancer, potentially due to limited antigen presentation, but the driving mechanisms of low T cell abundance remains unclear. Therefore, we defined and investigated programs ('gene modules'), related to estrogen receptor signaling (ERS) and immune signaling using bulk and single-cell transcriptome and multiplexed immunofluorescence of breast cancer tissues from multiple clinical sources and human cell lines. The ERS gene module, dominantly expressed in cancer cells, was negatively associated with immune-related gene modules TNFα/NF-κB signaling and type-I interferon (IFN-I) response, which were expressed in distinct stromal and immune cell types, but also, in part, expressed and preserved as a cancer cell-intrinsic mechanisms.

Article Synopsis
  • Researchers recorded humpback whale songs in Hawaii and Colombia, finding repeated acoustic patterns during their singing sessions.
  • The analysis showed that whales display cycles of acoustic complexity, correlating with their diving behavior and varying sound production over different time periods.
  • These variations suggest that humpback whales adjust their singing to optimize sound transmission and spatial detection, balancing between tonal and frequency-modulated elements.

Introduction: In high tuberculosis (TB) burden countries, the private sector manages a large proportion of initial visits by presumptive patients with TB. In Indonesia, the second largest contributor of TB cases globally, private practitioners (PPs) often do not adhere to national TB guidelines. A district public-private mix programme to mitigate this issue was started in 2019, yet engagement remains low.

There is increasing interest in health professions education (HPE) in applying argument-based validity approaches, such as Kane's, to assessment design. The critical first step in employing Kane's approach is to specify the interpretation-use argument (IUA). However, in the HPE literature, this step is often poorly articulated.

Background: A service-focussed placement model involves an innovative partnership between service and education providers to a) address service delivery needs and b) facilitate students' competency development. Services are collaboratively redesigned such that students are positioned as collaborators in service delivery with their learning supported through evidence-informed educational design. This model was implemented in the hospital setting and was found to promote positive patient outcomes.
