Collection:

Collection ID:CO000020
Collection Summary:Urine samples (early morning [second morning void) after a 10-hour fast]) collected from 44 overweight or obese participants in the IDEA trial at baseline and at 18 months of follow-up were selected from two subgroups (n=22 each): a group that exhibited radiographic progression and an age, race, sex, and BMI matched group who did not progress. Progression was defined radiographically by a ≥ 0.7mm decrease in medial JSW from baseline to 18 months while non-progression was defined as a decrease in medial JSW of ≤0.35mm . All subjects experienced knee pain and had radiographic evidence of tibiofemoral OA. For those people who were assigned an intervention that included exercise, the 18-month samples were collected at least 24 hours after the last acute bout of exercise training. In addition sampling was postponed (1-2 weeks after recovery from symptoms) in the event of an acute respiratory, urinary tract, or other infection. Urine was aliquoted and stored in cryovials at -80°C.

Sample Preparation:

Sampleprep ID:SP000033
Sampleprep Summary:Chenomx Internal Standard solution (70 ul) and 230 ul D20 was added to each of the 88 urine sample (400 ul), vortexed for 30s, and centrifuged at 12000 rcf for 5min. Chenomx ISTD (Chenomx, Edmonton, Alberta, Canada) contains 5mM 4,4-dimethyl-4-silapentane-1-sulfonic acid (DSS, Chemical Shift Indicator), 100 mM Imidazole (pH indicator), and 0.2% NaN3 (to inhibit bacterial growth) in D2O. 600 µl aliquot of the supernatant was transferred into 5mm NMR tubes (Bruker-Biospin, Germany). Phenotypic pooled urine samples were made by combining 200 µl aliquots from each of the study samples belonging to the same phenotype (Progressors-Baseline, Progressors-follow up, Non-progressors-baseline, and Non-progressors-follow up). In addition, a combined phenotypic pooled sample was also prepared by using 500 µl aliquot from each of the phenotypic pooled sample. Pooled NMR samples were prepared as described above and used as quality check (QC) samples.
