Article Synopsis
  • The paradox of the great speciators describes a conflicting pattern in avian lineages in Oceania that shows broad geographic distributions indicative of strong dispersal, yet also displays significant genetic divergence suggesting limited inter-island movement.
  • A study using genomic sequencing of dwarf kingfishers from northern Melanesia found deep genetic divergence and an absence of gene flow between nearby island populations, highlighting the paradox effectively.
  • The research proposes a framework based on founder effects and changing selection pressures that explains how diverse traits and environmental factors influence dispersal capabilities, shedding light on the evolutionary dynamics of these bird lineages.

Importance: The rapid expansion of telehealth transformed how primary care practices deliver care; however, uncertainties about the quality of telehealth-delivered care compared with in-person care remain. While there are concerns that increased telehealth may introduce wasteful care, how telehealth affects the delivery of low-value care is unknown.

Objective: To examine whether a primary care practice's level of telehealth use is associated with changes in the rates of low-value care.

This essay examines the impact of linguistic choices on the perception and regulation of assisted dying, particularly in Canada. It argues that euphemistic terms like "medical assistance in dying" and its acronym, "MAID," serve to normalize the practice, potentially obscuring its moral gravity. This contrasts with what is seen in Belgium and the Netherlands, where terms like "euthanasia" are used, as well as in France and the United Kingdom, where terminology remains divisive and contested.

Background: Advance Care Planning via Group Visits (ACP-GV) is a patient-centered intervention facilitated by a clinician using a group modality to promote healthcare decision-making among veterans. Participants in the group document a "Next Step" to use in planning for their future care needs. The next step may include documentation of preferences in an advance directive, discussing plans with family, or anything else to fulfill their ACP needs.

Article Synopsis
  • Critically ill patients with bloodstream infections (BSIs) who experience hypothermia are at a higher risk of death, but the impact of rewarming rates on their outcomes is not well understood.
  • In a study involving 3951 ICU admissions, researchers found that 8.4% of hypothermic patients had temperatures below 34.9°C, and lower temperatures were linked to higher severity of illness and a greater need for organ support.
  • The 90-day case-fatality rate was 22.9% overall, with significantly higher rates among those with lower temperatures; faster rewarming was associated with lower mortality rates even after accounting for illness severity and comorbidities.
