Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

30 participants (15 males and 15 females) who are ≥18 - ≤ 40 years old and considered healthy will be enrolled into this study to test the role of reactive oxygen species (ROS) in regulating cerebral blood flow (CBF). Participants can expect to be on study for 2 study visits over a 6 month period.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Accepts Healthy Volunteers:Yes
Standard Ages:ADULT
Inclusion CriteriaExclusion Criteria

  5. * Fasting blood glucose ≥100 mg/dl
  6. * LDL cholesterol ≥130 mg/dl
  7. * Triglycerides ≥150 mg/dl
  8. * Current diagnosis or history of:
  9. * peripheral vascular disease
  10. * hepatic disease
  11. * renal disease
  12. * lung disease
  13. * gastrointestinal disorders/bleeding
  14. * hematologic disease
  15. * stroke
  16. * myocardial infarction
  17. * coronary heart disease
  18. * congestive heart failure
  19. * heart surgery
  20. * prediabetes
  21. * diabetes mellitus (type 1, type 2, MODY, or others)
  22. * sleep apnea
  23. * hypertension
  24. * some autoimmune diseases, such as inflammatory bowel disease or systemic lupus erythematosus (exclusion at discretion of reviewing MD)
  25. * Current smoking, defined as the use of tobacco or nicotine products \>5 times in the past 30 days.
  26. * Cardiovascular medication use
  27. * NSAID sensitivity
  28. * Any contraindications of having an MRI
  29. * Irregular menstrual cycle (females only)
  30. * Medical conditions that can affect the menstrual cycle, such as hyperprolactinemia, prolactinoma, hypercortisolemia, and congenital adrenal hyperplasia (females only)
  31. * Pregnancy, breast feeding, or plans to conceive within the next 3 months (females only)
  32. * Polycystic ovary syndrome (females only)
  33. * Hirsutism defined as unwanted and/or excessive hair growth on the face, chest, or back (females only)
  34. * Levonorgestrel intrauterine device (IUD) (females only)
  35. * Hormonal birth control will not be allowed in women, in order to control for high variability between type, dose, and route of therapy. However, in discussion with Dr. Davis (Co-I) and Dr. Laura Cooney M.D., physician experts in medical and reproductive endocrinology and infertility, there are two broad exceptions to this birth control criteria:
  36. 1. Copper intrauterine devices (IUDs) will be allowed as they do not change systemic sex hormone levels).
  37. 2. Women currently taking hormonal birth control (i.e. contraceptive pills, patch, ring) for contraception only (not for a medical condition such as those listed in exclusion criteria above) may consider temporarily stopping to become eligible for enrollment. Hormonal birth control must be stopped at least one month prior to Study Visit 1 to provide time for menstruation to resume. Then stoppage continues through the last planned study visit. Screening information will be reviewed by endocrinology physicians to determine eligibility and timing on this issue (details below).
