This research study aims to better understand patient experiences with accessing genetic counseling services for hypermobile Ehlers-Danlos syndrome (hEDS). The study will include a review of MUSC medical records to better understand referral patterns to genetic counseling services among patients with hEDS. Patients with hEDS will also be asked to complete a survey about their experiences with accessing genetic counseling services. Healthcare providers will be asked to complete a separate survey about their experiences referring patients with hEDS to genetic counseling services and potential factors that may influence the referral process. The surveys will take approximately 10-15 minutes to complete.

There are minimal risks to participants but may include possible loss of confidentiality or discomfort when answering questions related to healthcare experiences. There is no direct benefit to participants, but the information provided may help improve access to genetic counseling services for future patients with hEDS. Participation in the surveys is completely voluntary.

This study is recruiting pediatric patients who have been diagnosed with Favorable Histology Wilms Tumor (FHWT). Wilms Tumor is the most common type of kidney cancer in children, and FHWT is the most common subtype. The goal of the study to improve outcomes within cohorts of FHWT patients with current long-term EFS rates at or below 80% and maintain outcomes despite therapy reduction within cohorts of FHWT patients with current long-term EFS rates at or above 84%. Common side effects of treatment in regards to this study include nausea, vomiting, hair loss, and fatigue (tiredness). Participants will receive the medications through an IV in their arm and orally. Study participation is expected to be approximately 5 years.

This is a randomized, double-blind, placebo-controlled, multicenter, parallel-group
study of the efficacy and safety of 2 weight-based treatment groups of plecanatide
versus placebo in children and adolescent participants 6 to less than 18 years of age with FC. Randomization will be stratified by sex to ensure balance across treatment groups.

Approximately 30 participants will be randomized to each of the Placebo, Low
Dose, and High Dose groups, within age group. Low Dose and High Dose will be
assigned once daily treatments based on the weight of the participant at
randomization to achieve weight-based dosing of 0.025 to 0.05 mg/kg in the Low
Dose treatment group and 0.05 to 0.1 mg/kg in the High Dose treatment group.

This trial is testing V118C in infants and toddlers.

V118C is an experimental vaccine. Vaccines help to prevent illness by teaching the body's immune system how to fight infections. The immune system is a network of organs and cells that fight infections. If it works, V118C may prevent an illness called pneumococcal disease. This is an illness caused by certain germs. These germs can cause infections, some of which may be serious, in the ears, nose, lungs, blood, or brain.

This trial will compare V118C to a vaccine called PCV20. PCV20 is approved to prevent pneumococcal disease in infants and toddlers.

This study is recruiting patients receiving cancer treatment that includes a type of drug called an "alkylating agent", which may cause side effects such as damage to the ovaries (female reproductive organs). The goal of the study is to determine the feasibility of conducting a cross network, multi-site, randomized clinical trial of triptorelin among newly diagnosed adolescent and young adult (AYA) female cancer patients age <40 years (exclusive of breast cancer). The triptorelin used in this study may affect how different parts of your body work such as your liver, kidneys, heart, and blood. Participants will receive the medications through an intramuscular (IM) injection in their arm. Study participation is expected to last up to three years.

The purpose of this research is to assess a stepped care model of a telehealth parenting program for children ages 2-6 years old with a neurodevelopmental diagnosis and behavior problems. Families will complete an online intake assessment, 6 group-based tele-health Parent-Child Interaction Therapy (PCIT) sessions, and an online post intervention assessment. Some families may receive additional individual virtual booster sessions and will complete a second online post assessment.

This study is recruiting pediatric patients who have been diagnosed with osteosarcoma. Osteosarcoma is the most common primary bone malignancy of childhood and adolescence. The goal of the study is to determine the feasibility of adding cabozantinib to standard MAP (high dose methotrexate, doxorubicin, and cisplatin) chemotherapy in patients with newly diagnosed metastatic osteosarcoma with a resectable primary tumor and to compare the effects, good and/or bad, of cabozantinib in combination with MAP versus MAP alone on people with newly diagnosed OST to find out which is better. Common side effects of chemotherapy include nausea, vomiting, hair loss, and fatigue (tiredness). Participants will receive the medications through an IV in their arm and PO. Study participation is expected to last up to 16 months.

The flu is caused by a virus that can sometimes change. This can make the flu resistant to treatment, which means drugs, like baloxavir marboxil, can become less effective for treating the flu (also known as "resistance").

The purpose of this study is to monitor changes in the flu virus before and after study treatment with baloxavir marboxil in children. The resistance of the flu virus to study treatment with baloxavir marboxil will also be monitored.

This is a randomized, double-blind, placebo-controlled, multicenter, 2-arm (1:1), parallel group, efficacy, and safety/tolerability fixed-dose study of SPN-812 in preschool-age children (4 to 5 years old) with a DSM-IV-TR diagnosis of ADHD. Approximately 286 subjects will be randomized to either SPN-812 or matching placebo in a 1:1 ratio (143 subjects per arm). Following up to 4 weeks of screening, subjects will be treated with study medication (SM) for 6 weeks, then will either be enrolled in a separate OLE study or followed for an additional 1 week for safety. The total duration of the study is up to 10 weeks.

This study is recruiting pediatric patients who have been diagnosed with rhabdomyosarcoma (RMS). RMS is a type of cancer that occurs in the soft tissues of the body. The goal of the study is to compare the effects, good and/or bad, of giving less chemotherapy drugs to people with very low risk-RMS to find out which is better. Patients will be separated into two groups based on their tumor type: Low Risk and Very Low Risk. Participants in the Low Risk group will receive Vincristine, Dactinomycin and Cyclophosphamide. Participants in the Low Risk group will receive Vincristine and Dactinomycin. All participants will be tested for genetic differences (called MYOD1 and TP53). If any participant is found to have these genetic differences, they will receive Vincristine, Dactinomycin and Cyclophosphamide. Common side effects of chemotherapy include nausea, vomiting, hair loss, and fatigue (tiredness). Participants will receive the medications through an IV in their arm. Study participation is expected to last up to one year.
