Fever is not considered a typical presentation of pertussis. We characterized fever among 7840 pertussis cases from the Centers for Disease Control and Prevention's Enhanced Pertussis Surveillance with cough onset from 2015 to 2022. Ten percent of cases had a reported fever.

In recent years, blooms of the neurotoxic dinoflagellate have been documented in Pacific Arctic waters, and the paralytic shellfish toxins (PSTs) that this species produces have been detected throughout the food web. These observations have raised significant concerns about the role that harmful algal blooms (HABs) will play in a rapidly changing Arctic. During a research cruise in summer 2022, a massive bloom of was detected in real time as it was advected through the Bering Strait region.

Commercially available insulin pumps for treatment of diabetes mellitus are currently not qualified to operate in the space environment. This work rigorously tested the fluid delivery performance of a Tandem t:slim X2 insulin pump in both micro- and hypergravity during a parabolic microgravity research flight. The parabolic research flight environment serves as an analogue to the types of transient gravitational loadings experienced during human-led missions, which provides a foundation to expand testing to suborbital and orbital flights in addition to other extreme environmental tests for wilderness dependency.

Changes in temperature and precipitation are already influencing US forests and that will continue in the future even as we mitigate climate change. Using spatiotemporally matched data for mean annual temperature (MAT) and mean annual precipitation (MAP), we used simulated annealing to estimate critical thresholds for changes in the growth and survival of roughly 150 tree species (153 spp. for growth, 159 spp.

Article Synopsis
  • * Data was collected from a national sample of 4,091 young adults (18-34) and analyzed using logistic regression to explore the relationship between neighborhood racial/ethnic and economic segregation and smoking behavior.
  • * Results revealed that residents in areas with higher concentrations of Hispanic/Latino and Black individuals had increased smoking risks, especially when compared to those in wealthier, predominantly White neighborhoods, highlighting the need for targeted tobacco reduction interventions.
