Official Title Phase I Study of the Safety and Feasibility of a Ketogenic Dietary Intervention to Improve Response to Immunotherapy

Purpose

This study will look at if a ketogenic diet (KD) can help treatment work better in patients with metastatic melanoma or metastatic kidney cancer. People who take part in the study will be randomly assigned to either continue eating their usual diet or trying the KD diet for 24 weeks. Participants will have blood and stool samples collected during the study. They will also test their sugar by doing daily glucose fingers sticks. Participants may be paid up to $200 for taking part in the study.

Could this study be right for you?

1. Patients with metastatic melanoma receiving first-line treatment with immunotherapy or Patients with metastatic renal cell cancer receiving first line treatment with immunotherapy.

2. Willing to give three stool samples

3. Willing to participate in a ketogenic diet (KD)

Age Range

18 years and up

Official Title Project Limb Rescue: A pilot study evaluating the feasibility of transcutaneous sensors for the detection of cancer-related lymphedema

Purpose

The goal of this study is to use new, adhesive-based sensors (pads that stick on your skin) to detect lymphedema, and to develop a way for patients to check for lymphedema at home.

This study will assist in distinguishing participants with lymphedema in comparison to participants without lymphedema at rest by using a combination of photoplethysmography (PPG) and bioimpedance (BI). Photoplethysmography is an optical technique that can be used to detect blood volume changes in tissue. Bioimpedance evaluates how tissue responds to an externally applied electrical current.

Could this study be right for you?

• History of cancer-related lymphedema, cancer in your arm, or the lymph nodes in the arm
• History of cancer therapy with surgery or radiation involving the axillary basin and upper arm that requires compression or pneumatic therapy
• Physically capable of performing a brief bike riding exercise for about seven minutes
• No metal implants
• Willingness to take off shoes and any metal jewelry
• Not currently pregnant
• Not currently incarcerated

Age Range

18 - 90 years

Official Title An Intervention Study about Primary Care Algorithms for Early Identification of Young Women with von Willebrand Disease

Purpose

Researchers at Nationwide Children’s Hospital are seeking volunteers to be a part of a study looking at how to best screen for bleeding disorders in young women.

Participants will be asked to complete questionnaires. If their survey answers suggest they have heavy menses or abnormal bleeding, they will also be asked to have a blood draw on the same day.

Could this study be right for you?

• Are 9 to 21 years old
• Have had your first menstrual cycle

Age Range

9 - 21

Official Title Radiotracer Imaging of Lower Extremity Skeletal Muscle Perfusion in Patients with Peripheral Arterial Disease

Purpose

The purpose of this study is to study a new method to evaluate blood flow to the calves and feet. We hope this information can help evaluate the effectiveness of treatments and predict clinical outcomes. Participants will be required to attend one (2 hr) session at Nationwide Children's Hospital.

Could this study be right for you?

-Diagnosis of Peripheral Arterial Disease (PAD) OR leg symptoms, such as muscle pain or cramping AND/OR foot wound that has required medical consultation

• Healthy volunteers must:
• Be at least 40 years of age
• Have no history of cardiovascular disease (including high blood pressure)

Official Title Biomarkers of Sickle Cell Lung Disease -BOLD

Purpose

This is a study to determine risk factors for developing lung disease in children with sickle cell disease (SCD). Specifically we are researching factors that lead to the development of Acute Chest Syndrome, a pneumonia-like illness that affects many children with SCD.

Could this study be right for you?

• Diagnosis of Sickle Cell Disease (SCD)
• Under the age of 19
