What does the body of evidence say on the topic of osteoporosis? Plus: we look at a genuinely breakthrough therapy for metastatic melanoma, and Chris lets you in on a troubling “secret” when it comes to travel health insurance! You will also learn what a “dowager’s hump” is and hear Chris sing, and for that we formally apologize.

Block 1:

(2:01) Osteoporosis: what it is; bone cells and how they are assessed

Block 2:

(9:02) Osteoporosis: bone mineral density, T-score and Z-score; can doctors see signs of osteoporosis in the clinic; causes of osteoporosis; treating it: lifestyle changes, supplements, bisphosphonates, and Prolia; screening guidelines

Block 3:

(32:04) Breakthrough therapy for metastatic melanoma: TILs (vs. ipilimumab)

Block 4:

(47:53) Travel insurance caveat
