Jack Sewell Cooper, M.D. of Miami Dies at Age 85

Dr. Cooper knew from a young age that he wanted to be a doctor, and the dream became a reality in 1965 when he completed his medical degree from the University of Virginia School of Medicine.
Dr. Cooper completed an internship at Jackson Memorial Hospital in Miami and then completed his residency in orthopedics and rehabilitation at the University of Miami School of Medicine. He also served as a clinical assistant professor there.
During his tenure at the Doctor’s Hospital in Miami, Florida, he served in various leadership roles, including president of the medical staff, and chief medical officer.
Cooper was born on January 26, 1939, to Jack Ellis and Mary Ruth Cooper. He graduated from Appalachia High School in Appalachia, Virginia in 1957.
“Jack was diagnosed with polio when he was in high school which reinforced his desire to become a doctor. He guided his family and patients through broken bones, replaced knees and joints, shoulder injuries, and surgeries,” his family wrote.
In between his training for orthopedic surgery, he served in the United States Navy Corp. for four years.
When Dr. Cooper wasn’t in the operating room, he enjoyed woodworking, photography, and spending time on his boat swimming and deep-sea fishing.
Cooper was predeceased by his parents, his grandmother, Doni Sewell, and three brothers, Joe Cooper, Ben Cooper, and Tom Cooper.
He leaves behind his wife Debbi, his son Mark, and his granddaughter Kaylynn Lee. He will also be missed by his sister Doni Cooper Duckett, brother Sid Pat Cooper and many nieces and nephews.

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
