Retrospective cohort study of trends in the use of outpatient parathyroidectomy by surgical indication.

Background: A shift toward outpatient parathyroidectomy was seen in the early 2000s. Recent trends, especially for secondary and tertiary hyperparathyroidism, have not been described. This study evaluates temporal trends in same-day, overnight, and inpatient parathyroidectomy by surgical indication.

State shifts in the deep Critical Zone drive landscape evolution in volcanic terrains.

Volcanic provinces are among the most active but least well understood landscapes on Earth. Here, we show that the central Cascade arc, USA, exhibits systematic spatial covariation of topography and hydrology that are linked to aging volcanic bedrock, suggesting systematic controls on landscape evolution. At the Cascade crest, a locus of Quaternary volcanism, water circulates deeply through the upper [Formula: see text]1 km of crust but transitions to shallow and dominantly horizontal flow as rocks age away from the arc front.

Airway-resident memory CD4 T-cell activation accelerates antigen presentation and T-cell priming in draining lymph nodes.

Specialized memory CD4 T cells that reside long-term within tissues are critical components of immunity at portals of pathogen entry. In the lung, such tissue-resident memory (TRM) cells are activated rapidly after infection and promote local inflammation to control pathogen levels before circulating T cells can respond. However, optimal clearance of Influenza A virus can require TRM and responses by other virus-specific T cells that reach the lung only several days after their activation in secondary lymphoid organs.
