Antigen presentation by tumor-associated macrophages drives T cells from a progenitor exhaustion state to terminal exhaustion.

Whereas terminally exhausted T (Tex_term) cells retain anti-tumor cytotoxic functions, the frequencies of stem-like progenitor-exhausted T (Tex_prog) cells better reflect immunotherapeutic responsivity. Here, we examined the intratumoral cellular interactions that govern the transition to terminal T cell exhaustion. We defined a metric reflecting the intratumoral progenitor exhaustion-to-terminal exhaustion ratio (PETER), which decreased with tumor progression in solid cancers.

Combination checkpoint blockade and laser interstitial thermal therapy in radiographically progressive non-small cell lung cancer brain metastases.

Background: Laser interstitial thermal therapy (LITT) is a minimally invasive surgical treatment being employed frequently for radiographically progressive brain metastases. Considerable interest exists in combining LITT-mediated in situ vaccination to license immune checkpoint blockade (ICB). No studies have examined the clinical feasibility of this combination in brain metastases.

Why Do Patients Opt for the Emergency Department over Other Care Choices? A Multi-Hospital Analysis.

Introduction: There are several options for receiving acute care besides emergency departments (ED), such as primary care physician (PCP) offices, urgent care centers (UCC), and telehealth services. It is unknown whether these alternative modes of care have decreased the number of ED visits for patients or whether they are considered before visiting the ED. A comprehensive study considering all potential methods of care is needed to address the evolving landscape of healthcare.

Enabling osteoporosis treatment in post-acute care: An algorithm for providers.

Approximately 60 % of older adults with a hospitalized fracture receive post-acute care in a skilled nursing facility (SNF), yet fewer than 10-20 % receive osteoporosis treatment following a fracture. This study sought to understand SNF providers' perspectives on osteoporosis treatment and to receive feedback on a pocketcard to guide osteoporosis treatment in the post-acute care setting. We interviewed 17 SNF providers with 2+ years of post-acute care experience from 13 states.
