Brief Summary:
With better medical care, patients with cystic fibrosis (CF), a life-threatening disease, are enjoying longer lives. As the CF life expectancy increases, conditions such as CF-related diabetes (CFRD) become more prevalent. Nutrition plays a major role in maintaining optimal health in cystic fibrosis (CF). This project is designed to investigate nutrition-related factors, such as diet and body composition, on outcomes in patients with CF. The data generated from this study will be used to inform future nutrition intervention studies in adults with CF and CFRD.

Condition or disease
Cystic Fibrosis

Detailed Description:
Research methods include blood draws for plasma markers of oxidative stress and metabolomics (the measurement of thousands of small chemicals in the blood), magnetic resonance imaging (MRI, to assess energy capacity and thigh fat), dual energy X-ray absorptiometry (DEXA, to assess total and regional body fat and muscle), and indirect calorimetry (to assess resting energy expenditure and whole body fat oxidation). Clinically-relevant data, such as lung function, CF genotype, and diabetes status will be obtained from the electronic medical record and the CF Registry.

Cross-sectional, observational study
Subjects with CF in a vitamin D study
This is a longitudinal observational study in subjects enrolled in a high-dose vitamin D study. The investigator (Jessica Alvarez) does not assign the intervention to the subjects of the study.

Primary Outcome Measures :
  1. Acylcarnitine analysis by high-resolution liquid chromatography mass spectrometry [ Time Frame: Baseline for cross-sectional study and 1 year for longitudinal study ]
    This will pe performed using targeted metabolomics methods

Secondary Outcome Measures :
  1. quantitative plasma levels of specific plasma acylcarnitines [ Time Frame: Baseline for cross-sectional study and 1 year for longitudinal study ]
    This will be measured in fasted blood

Other Outcome Measures:
  1. whole-body fasting fat oxidation [ Time Frame: Baseline for cross-sectional study and 1 year for longitudinal study ]
    This will be assessed using indirect calorimetry

  2. 31P-magnetic resonance spectroscopy (MRS)-derived measures of resting thigh skeletal muscle bioenergetic metabolism [ Time Frame: Baseline for cross-sectional study ]
    This will be assessed using MRI

Biospecimen Retention:   Samples Without DNA
We will collect sputum, urine, and blood.
