Assessment of Remote Approaches for Identification of Autonomic Dysfunction Among Survivors of Leukemia and Lymphoma
What this study is about
This study seeks to determine if diagnosing cardiac autonomic dysfunction (AD) can be done remotely with the same accuracy as in-person testing. If so, the identification of AD could happen sooner, facilitating remote studies of the condition and potentially reducing the risk of illness.
View original scientific description
This study seeks to determine if diagnosing cardiac autonomic dysfunction (AD) can be done remotely with the same accuracy as in-person testing. If so, the identification of AD could happen sooner, facilitating remote studies of the condition and potentially reducing the risk of illness. Childhood cancer survivors, particularly survivors of acute lymphoblastic leukemia (ALL) and Hodgkins's lymphoma (HL), appear to be at increased risk for AD. Primary Objectives: * To determine the sensitivity and specificity of heart rate variability (HRV), measured remotely with biosensor technology (Actigraph LEAP), compared to in-person assessment using the Ewing battery as the reference standard to identify cardiac autonomic dysfunction (AD) among survivors of leukemia and lymphoma. * To determine the sensitivity and specificity of the Composite Autonomic Symptom Scale 31 (COMPASS31) compared to the Ewing battery to identify AD among leukemia and lymphoma survivors.
Interventions
OTHER
Exercise Intervention - Ewing Battery Assessment
Undergo in-person Ewing battery assessment
OTHER
Questionnaire Administration
Receive COMPASS31 questionnaire
DEVICE
Medical Device Usage and Evaluation
Wear biosensensor heart monitor that remotely collects heart rate variability.
Primary outcome measures
Heart rate variability (msec)
Time frame: Up to 7 days after the on-campus study visit
The standard deviation of normal-to-normal heartbeat intervals over a 24-hour period measured in milliseconds
Abbreviated Composite Autonomic Symptom Score (0-100)
Time frame: During the on-campus study visit (Day 1)
Symptom burden-based questionnaire of six weighted domains (orthostatic intolerance, vasomotor, secretomotor, gastrointestinal bladder and pupillomotor) Abbreviated Composite Autonomic Symptom Score: * This questionnaire, administered during Day 1, generates a weighted score from 0 to 100, and questions fall into one of six domains: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor function. Scores are determined by applying a simplified scoring algorithm. * Overall score interpretation: * \< 3 or less: Mild * 3-7: Moderate * \>7: Severe
Ewing Score (0-5)
Time frame: During the on-campus study visit (Day 1)
Derived from sum of five individual autonomic test scores Ewing Battery Scoring: * This battery is administered during Day 1. Each test within the battery (5 tests total) is assigned a score of 0 (normal), 0.5 (borderline), or 1 (abnormal). * Overall score interpretation: * 0-1: Considered normal autonomic function * 1.5-2: Mild autonomic dysfunction * 2.5-3: Moderate autonomic dysfunction * 3.5-5: Severe autonomic dysfunction

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
