Plague is a rare, potentially fatal flea-borne zoonosis endemic in the western United States. A previous model described interannual variation in human cases based on temperature and lagged precipitation. We recreated this model in northeastern Arizona (1960-1997) to evaluate its capacity to predict recent cases (1998-2022).

A previous laboratory study using Haemaphysalis longicornis Neumann (Acari: Ixodidae) ticks of North American origin showed that larvae could acquire the Lyme disease spirochete, Borrelia burgdorferi sensu stricto (s.s.) (Spirochaetales: Spirochaetaceae) while feeding to completion on infected mice.

In response to notable increases in tick-associated illnesses in the United States, recent public health policies encouraged multi-sector collaborative approaches to preventing vector-borne diseases. Primary prevention strategies focus on educating the public about risks for tick-borne diseases and encouraging adoption of personal protection strategies. Accurate descriptions of when and where people are at risk for tick-borne diseases aid in the optimization of prevention messaging.

Article Synopsis
  • Ixodes scapularis and Ixodes pacificus ticks are known vectors for various pathogens, but their potential role in transmitting Bartonella spp. has been questioned, with previous studies showing these ticks lacked Bartonella spp.
  • A recent study tested 792 I. scapularis, 45 I. pacificus, and 16 I. angustus ticks from rodents in Minnesota and Washington for Bartonella using advanced PCR techniques, while also examining rodents and fleas from the same areas.
  • Results showed high prevalence of Bartonella spp. in rodents (25.6% to 27.9%) and fleas (36.8% to 45.2%), but only one larval I. scapularis tick tested

Background: Limited treatment options exist for inoperable thyroid cancers. We evaluated whether neoadjuvant use of systemic tyrosine kinase inhibitors facilitates surgery of differentiated thyroid cancers in this challenging context.

Methods: A single-institution experience of 42 patients receiving tyrosine kinase inhibitors for papillary, follicular and anaplastic thyroid carcinomas between 2018 and 2023 was reviewed to identify differentiated thyroid cancers treated with neoadjuvant tyrosine kinase inhibitors (dabrafenib/trametinib, lenvatinib/pembrolizumab, or lenvatinib alone) via multidisciplinary protocols.
