Article Synopsis
  • - The study investigated the higher risk of sinus node dysfunction (SND) that leads to pacemaker implantation and mortality among first-degree relatives of patients with pacemakers due to SND.
  • - Data was collected from various Danish health registries, tracking over 6 million individuals from 1982 to 2022, and findings indicated that those with a family history of SND had a significantly higher risk (RR = 2.9) of requiring a pacemaker compared to the general population.

  • - The study aimed to assess how different anesthetics (isoflurane, sevoflurane, desflurane) affect induced hypothermia and rewarming times in Hispaniolan Amazon parrots, while also evaluating their cardiovascular and respiratory responses.
  • - Twelve adult parrots were used in a randomized trial where they were anesthetized with the three inhalants, and various temperature-related times during anesthesia were recorded and analyzed.
  • - Results showed that all anesthetics induced hypothermia at similar rates, but sevoflurane led to a significantly longer rewarming time compared to desflurane; transient apnea and heart rhythm issues were noted across all treatments.
