Estimation of Muscle Mass in Older Adults Using Deuterated Creatine (MM-DC)
Sarcopenia
About this trial
This is an interventional prevention trial for Sarcopenia focused on measuring Sarcopenia, Mass muscle, Quality of life
Eligibility Criteria
Inclusion criteria
Population 1: Community-dwelling older adults:

- ADL (activity of daily living) equal to 5 or more prior to the fracture
Exclusion criteria
Population 1:Community-dwelling elderly:
- Diagnosis of dementia
- Presence of cognitive impairment (assessed during clinical follow-up using standardized cognitive tools such as MMSE (Mini Mental Status Examination) or MOCA (Montreal Cognitive Assessment), during pre-screening period).

Population 1
Population 2
(Community-dwelling older adults) will participate in the study for approximately 65 days. Population 1 will absorb deuterated creatine 30 mg, a non-radioactive, stable isotope of creatine, for the estimation of muscle mass in humans. The estimation of muscle mass will be made on 2 separate occasions in the community-dwelling elderly population in order to assess reproducibility of the method when tested approximately 60 days apart.
(Hip-fracture patients) will participate in the study for approximately 35 days during their in-hospital period, followed by 30 during their post-discharge period, so for a total period of at least 65 days. Population 2 will absorb deuterated creatine 30 mg, a non-radioactive, stable isotope of creatine, for the estimation of muscle mass in humans. In the hip fracture population, estimation of muscle mass by the D3 creatine method will be performed on up to 3 separate occasions to assess whether the method is sensitive enough to detect decreases in muscle mass that may occur during the recovery period after hip fracture.
