RI-MUHC Annual Report





Understanding the health impact of inactivity for the benefit of older adults—and astronauts!

Directed by Dr. José A. Morais at the Centre for Innovative Medicine, a study was launched this year using bedrest as an analog to microgravity to provide data for eight Canadian research projects. Funding: CIHR.

Strategies to reduce breast cancer growth and related skeletal lesions

With international partners, Dr. Shafaat Rabbani’s team presented a novel approach to target both tumour growth and the skeletal lesions caused by breast cancer-induced bone disease. First author: doctoral student Niaz Mahmoud, Bone Research. Funding: CIHR.

Vaccine efficacy and hemodialysis

Dr. Rita Suri showed that most dialysis patients do not develop adequate antibodies with one dose of SARS-CoV-2 vaccine. Her study in CMAJ advised that patients receiving hemodialysis be prioritized for a second BNT162b2 [Pfizer] dose at the recommended three-week interval.
