Beskrivelse
Inclusion Criteria:
- Age 35-80 years
- Diagnosis of metastatic cancer with cachexia (≥5% drop in body mass in less than 12 months), metastatic cancer without cachexia (<5% drop in body mass in 12 months) or no history of cancer but similar in age and sex as other groups.
Exclusion Criteria:
- Current use of vitamin D analogs
- Fasting plasma glucose ≥126 mg/dL
- Renal failure (serum creatinine > 1.5mg/dl)
- Chronic active liver disease (Bilirubin > 17mmol/L, AST>144IU/L, or ALT>165IU/L)
- Contraindications to MRI (e.g., pacemaker, ferrous materials within body).
- Active coronary artery disease or history of unstable macrovascular disease (unstable angina, myocardial infarction, stroke, and revascularization of coronary, peripheral or carotid artery within 3 months of recruitment)
- Renal insufficiency/failure (serum creatinine > 1.5mg/dl)
- Oral warfarin group medications or history of blood clotting disorders.
- People who have taken Bevacizumab
- Platelet count <100,000 per uL
- Pregnancy or breastfeeding
- Alcohol consumption greater than 2 glasses/day or other substance abuse
- Untreated or uncontrolled thyroid disorders
- Debilitating chronic disease (at the discretion of the investigators)
- Previous injury/trauma/surgery to the region being measured without full recovery
- Pain in the area to be assessed
- Any medical condition affecting the ability to execute a maximal muscle contraction
- The presence of infections, highly communicable diseases (AIDS, active tuberculosis, veneral disease, hepatitis) or metastatic bone disease that may interfere with safely executing maximal effort.
- Significant neurological or musculoskeletal disorders or disease that may interfere with safely executing maximal contraction
- Any congenital, developmental, or other bone disease or previous surgeries that may interfere with successful testing

Skeletal muscle protein synthesis
Tidsramme: Approximately within a month of recruitment
|
Muscle protein synthesis will be measured in the postabsorptive state from the rate of incorporation of isotopically labeled amino acids given intravenously.
