Microbial activity in the deep continental subsurface is difficult to measure due to low cell densities, low energy fluxes, cryptic elemental cycles and enigmatic metabolisms. Nonetheless, direct access to rare sample sites and sensitive laboratory measurements can be used to better understand the variables that govern microbial life underground. In this study, we sampled fluids from six boreholes at depths ranging from 244 m to 1,478 m below ground at the Sanford Underground Research Facility (SURF), a former goldmine in South Dakota, United States.

The biological pathways connecting ambient fine particulate matter (PM)-induced initial adverse effects to the development of atherosclerotic cardiovascular diseases are not fully understood. We hypothesize that lysoglycerophospholipids (LysoGPLs) are pivotal mediators of atherosclerosis induced by exposure to PM. This study investigated the changes of LysoGPLs in response to PM exposure and the mediation role of LysoGPLs in the pro-atherosclerotic effects of PM exposure.

Purpose: National Comprehensive Cancer Network Guidelines recommend initiating postoperative radiation therapy (PORT) within 6 weeks of surgery for patients with head and neck squamous cell carcinoma (HNSCC), but delays affect 50% of patients, disproportionately burden minoritized groups, and contribute to worse oncologic outcomes. This trial evaluates the efficacy of Navigation for Disparities and Untimely Radiation thErapy (NDURE), an enhanced navigation-based intervention, relative to usual care (UC) patient navigation for starting timely PORT.
Methods: Adults with locally advanced HNSCC planning to undergo surgery and PORT were randomly assigned 1:1 to standard multidisciplinary head and neck oncology care and either NDURE, a multilevel navigation-based intervention to enhance key processes of care and overcome barriers to timely PORT, or UC, which consisted of standard patient navigation.

In 2020, the Centers for Medicare and Medicaid Services reintroduced Alzheimer's disease and related dementias to its risk-adjustment payment model for Medicare Advantage (MA) plans. Using 2017-20 data for 100 percent of community-dwelling beneficiaries enrolled in Medicare, we evaluated how the reintroduction of dementia to the risk-adjustment model affected rates of new (incident) dementia diagnoses among beneficiaries enrolled in MA relative to those enrolled in traditional Medicare. In response to the payment change, annual incident dementia diagnosis rates in MA increased by 11.

Introduction: Prolonged activation of the body's stress response from chronic exposure to adverse stressors may have a significant impact on lifelong psychosocial functioning. Screening for the impact of prolonged adversity in childhood has become an integral component of pediatric care. While past research has separately explored the impact of caregiver chronic illness and caregiver toxic stress on children, the relationship between caregiver chronic illness disability burden, caregiver parental toxic stress, and their child's psychosocial functioning is not well understood.

Lung cancer is the leading cause of cancer mortality globally, with non-small cell lung cancer (NSCLC) accounting for 85% of cases. Despite advancements in first-line treatments such as immunotherapy and targeted therapies, resistance to these treatments is common, creating a significant unmet need for effective second-line therapies. This review evaluates current and emerging second-line therapeutic options for advanced or metastatic NSCLC, focusing on their efficacy and potential to improve patient outcomes.

The GD-1 stellar stream exhibits spur and gap structures that may result from a close encounter with a dense substructure. When interpreted as a dark matter subhalo, the perturber is denser than predicted in the standard cold dark matter (CDM) model. In self-interacting dark matter (SIDM), however, a halo could evolve into a phase of gravothermal collapse, resulting in a higher central density than its CDM counterpart.
