New Case
39-year-old man originally from Guatemala, who moved to one of the NYC boroughs in 2023 and currently lives with his siblings and cousins, presented with headaches. He reports headaches for several months, possibly nearly 1 year. Over the past 2 weeks, he has had intermittent numbness on the left side of his face and in his left arm and foot, with difficulty standing due to sensory changes in his feet. He states these symptoms are new. He reports a fall related to the numbness but denies balance problems. He denies fever or chills. He has intermittent nausea and vomiting but denies diarrhea, abdominal pain, or other complaints. He works as a busboy in a restaurant and states that he only cleans and does not prepare food. In Guatemala, he used to eat street tacos containing pork and beef, sometimes with undercooked meat. He is a former smoker who quit 4 years ago after smoking for 10 years. He drinks alcohol 3–4 times per week, typically 2–4 drinks per occasion, but not daily. He reports no sexual activity for 1–2 years.

New Case
3 yo child who recently immigrated to the US from Central America is brought in to the ER with acute right lower quadrant abdominal pain. The mother is concerned about the pain as well as nausea and vomiting. This is acute and the ER provider is concerned that this might be an acute surgical emergency. They order an US in this child and they are surprised to see a rather active serpiginous wormlike 'thing' wiggling away in the child's appendix. I was sent the Ultrasound video which I really enjoyed. What to do?

New Case
Male in his 20s from Hokkaido, Japan, developed fatigue and rash, followed by fever and myalgia 6 days later. He was a group of five individuals on a hunting trip prior to this and reports that 3 friends are just fine but one other individual developed similar symptoms. He reports that they had been hunting the Ussuri brown bear, which is larger and more aggressive than the Asian black bear. They had been successful and all five of them had consumed well cooked bear meat. He does share that he is aware of infectious risk from eating bear and thus the meat was well cooked. He and the one fellow hunter who did get sick were unique in that they each ate one of the eye balls raw. This is a tradition that is felt to give the consumer the great vision that these animals are purported to have.

Dear TWiP listeners,
Have you ever wondered how TWiP shapes your understanding of science? We have! To find out more, Christina and the team are running a survey based study to learn more about how TWiP contributes to your scientific literacy and trust in science. Listen to the segment in this episode (TWiP 267) where Christina discusses the study's aims and scope.
Anyone who listens to TWiP can participate. The survey is anonymous and we do not collect personal data that could identify you. There are no potential disadvantages or harms in taking part, other than using a few minutes of your time. You will receive no direct benefit from taking part in this study. However, the information that is collected during this study will give us a better understanding of who our listeners are, and why they choose to listen to TWiP. We can use this understanding to make TWiP even better!
This is an academic study and we aim to disseminate our findings to the wider public, including you. For example, we'll have a conversation about the findings on a future episode of TWiP, we plan conference presentations and publication in a relevant academic journal
The project has been reviewed and approved by the University of Glasgow College of Medical, Veterinary & Life Sciences Ethics Committee. Application 200250013
