The main reason for this research study is for researchers to evaluate the relationship between congenital heart disease and development. Currently, there is not enough long-term information available to researchers to predict a child's development if they have been diagnosed with Ductal Dependent Pulmonary Blood Flow (DDPBF), a type of congenital heart disease.

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 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.

Epidermolysis Bullosa (EB) is a rare, inherited skin condition that makes the skin extremely fragile, causing painful blisters and wounds from even minor friction or injury. There is currently no cure, and because EB is uncommon, doctors still have limited high-quality data to guide the best treatment and long-term care. This study is part of a large North American effort to collect and organize health information from people with EB into a secure database. By tracking how the disease progresses over time, along with symptoms, complications, and treatments, researchers hope to better understand EB and improve care for future patients. Participation involves consenting to share medical record information and optionally completing brief questionnaires during routine clinic visits or by email. No experimental treatments or extra medical procedures are involved. While there is no direct benefit to participants, the knowledge gained may help improve care and support the development of new treatments in the future.

This study is a double‑blind, placebo‑controlled research study to evaluate the safety and effectiveness of a skin patch treatment for peanut allergy in children ages 1 to 3. The patch delivers a very small amount of peanut protein through the skin and is designed to help the immune system become less sensitive to peanuts over time.

Participation in the study will last approximately 34 weeks. Participation is voluntary, and participants may withdraw at any time.

The investigational varicella vaccine (hereafter referred to as VNS vaccine) is a new
candidate varicella vaccine derived from the Oka strain. The main rationale for the
development of VNS vaccine is to provide an additional alternative varicella vaccine as an advantage from a public health perspective to prevent varicella disease

The overall goal of this study is to learn how to best support teens with CHD to improve their health and quality of life. Adolescents with moderately and severely complex CHD experience considerable risk of mental health comorbidities. Psychological health is important to cardiovascular health and related outcomes. This study will evaluate the effectiveness of a well-being focused telemedicine intervention in adolescents with CHD. The study is to learn if the WE BEAT program helps teens with CHD improve their ability to cope with stress and anxiety. The study will also create a data bank to study connections between mental health, heart health and biomarkers (hair, saliva, urine, blood samples).

Children with amblyopia (lazy eye) are often treated with patch therapy. Patch therapy often results in leftover amblyopia and has many challenges associated with its use. This study will determine how traditional patch therapy results compare to those achieved with the Luminopia digital therapeutic system.

Cutaneous lupus is a common manifestation of childhood-onset Systemic Lupus Erythematosus (cSLE), affecting up to 85% of patients. Skin involvement can cause irritation, scarring, hair loss, changes in skin color and appearance, which may negatively impact quality of life and mental health. This study aims to assess the impact of cutaneous lupus on quality of life and mental health in diverse pediatric populations, with the goal of identifying disparities and improving individualized care. We will use validated surveys to assess disease burden on quality of life.
