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.

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 undergo a finger prick blood test and 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)
• Have no history of diabetes mellitus
• Be a non-smoker
• Have normal BMI

Age Range

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
