An island doctor sprang to the assistance of NBC Today Show host Hoda Kotb as she started to lose her voice, jeopardising her performance on a live broadcast from Bermuda.

Kyjuan Brown, the owner of Northshore Medical and Aesthetics, delivered a shot to the television personality, which helped her to continue co-hosting two episodes of the Hoda & Jenna Trippin’ travel series that showcased the island.

Ms Kotb and cohost Jenna Bush Hager gave Dr Brown, an invited audience member, a shout-out for the timely intervention.

"Dr Brown came to my rescue at a critical moment, ensuring not just my health but the continuation of our show," Hoda remarked during the live recording.

A spokeswoman for the physician said: “Renowned as the doctor to celebrities, Dr Brown was invited as a guest on the show.

“However, Dr Brown's role took an unexpected turn just a day prior when he was urgently called upon to provide medical assistance to host Hoda Kotb, ensuring her ability to participate in the live broadcast.”

Later in the show, co-host Ms Bush Hager, the daughter of former US president George W. Bush, also thanked the doctor for his role in saving the day.

Responding to the accolades, Dr Brown said: "A doctor is never off duty but I am happy to serve and be a part of this amazing experience."

The spokeswoman added: “Dr Brown's exemplary commitment and swift action not only safeguarded the health of one of our beloved hosts but also ensured the smooth execution of the Bermuda Bash Today Show episode, contributing to its overwhelming success.”
