The World Anti-Doping Agency is investigating whether hyaluronic acid could be used to alter a ski jumper’s suit surface area.

1. Travel Medicine Podcast 1218, "Valentine Special-Journal Club," mixes holiday science with medical cases tied to romance, labor timing, and heart attack risk. 2. Dr. J is the internal medicine host and Dr. Santosh is the pediatric infectious disease host and researcher, and both frame the episode with journal-club commentary. 3. The episode asks what love, timing, and stress do to the body, using studies that link relationships to microbiomes, immune changes, labor duration, and cardiac events. 4. The opening story describes a 24-year-old Frenchman in Toulouse who arrived with unspecified pain and was found to have an 8-inch, 37-millimeter brass-and-copper shell in his rectum. 5. The hosts say the shell was unexploded at removal and that a bomb squad had to be called to the hospital because of detonation concerns. 6. They contrast that case with an 88-year-old patient in Toulon who also had an 8-inch artillery shell removed, this time through abdominal surgery. 7. The shell story is used as the lead-in to a Valentine’s special about "the things we do for love and romance and maybe just a good time." 8. A 60-year Wisconsin longitudinal cohort of 408 adults aged 58 to 91 found that spouses had more similar microbiomes than siblings. 9. The similarity was strongest in couples reporting close relationships, and it held up after accounting for dietary factors. 10. The hosts note that the comparison involved fecal microbiota and that the study also considered bacteria from skin and other body sites. 11. A second study examined 47 women in new exclusive romantic relationships, with 115 immune cell samples and repeated surveys over time. 12. The researchers compared women who were not in love, newly in love, and out of love, and they used follow-up blood draws when relationships changed or 12 months passed. 13. Of three hypotheses, the reproductive life history theory had the strongest support, which the hosts connect to immune changes during early romantic attachment. 14. They report 61 gene transcripts changing by more than 15 percent and describe shifts in CD4, CD8, B cells, monocytes, and dendritic cells. 15. The same study found elevated plasma nerve growth factor in new-love participants relative to single people and those in long-term relationships. 16. The hosts say nerve growth factor normalized after 12 to 24 months in participants who stayed in the same relationship. 17. The tone stays conversational and comic, with rapid back-and-forth interruptions, medical clarifications, and repeated jokes about derailing the conversation. 18. The format is a journal-club discussion that moves from grotesque case reports into study summaries and practical interpretation. 19. Listeners interested in microbiome research, reproductive immunology, and obstetric timing will get the most from it. 20. Listeners wanting a straight news readout without jokes or digressions may skip it.
