The goal of this trial is to learn how the Safe Dates for Young Parents (SDYP) intervention affects the sexual and reproductive health behaviors, and quality of, and attitudes surrounding intimate partner relationships in adolescents and young adults (AYA) assigned female sex at birth who are pregnant or parenting. The main questions it aims to answer are: - Will the SDYP intervention have any effect on the sexual and reproductive health behaviors during the study period? - Will the SDYP intervention have any effect on the prevention or reduction of intimate partner violence (IPV)? - Will the SDYP intervention have any effect on the attitudes and beliefs about healthy relationships? Researchers will compare the behaviors, attitudes, and beliefs about sexual and reproductive health and relationships of participants assigned to the SDYP intervention group to participants assigned to the control (non-SDYP intervention) group to see if there is any difference or changes in those behaviors, attitudes, and beliefs before-and-after or without the SDYP intervention. Participants in the SDYP intervention will attend ten (10) 50-minute group sessions that will involve interactive discussions, thinking through life-like scenarios, games, role-plays, brainstorming, and a poster contest and theatrical play.

Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma. Another aim of the study it to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.

The Pediatric Dose Optimization for Seizures in Emergency Medical Services (PediDOSE) study is designed to improve how paramedics treat seizures in children on ambulances. Seizures are one of the most common reasons why people call an ambulance for a child, and paramedics typically administer midazolam to stop the seizure. One-third of children with active seizures on ambulances arrive at emergency departments still seizing. Prior research suggests that seizures on ambulances continue due to under-dosing and delayed delivery of medication. Under-dosing happens when calculation errors occur, and delayed medication delivery occurs due to the time required for dose calculation and placement of an intravenous line to give the medication. Seizures stop quickly when standardized medication doses are given as a muscular injection or a nasal spray. This research has primarily been done in adults, and evidence is needed to determine if this is effective and safe in children. PediDOSE optimizes how paramedics choose the midazolam dose by eliminating calculations and making the dose age-based. This study involves changing the seizure treatment protocols for ambulance services in 20 different cities, in a staggered and randomly-assigned manner. One aim of PediDOSE is to determine if using age to select one of four standardized doses of midazolam and giving it as a muscular injection or nasal spray is more effective than the current calculation-based method, as measured by the number of children arriving at emergency departments still seizing. The investigators believe that a standardized seizure protocol with age-based doses is more effective than current practice. Another aim of PediDOSE is to determine if a standardized seizure protocol with age-based doses is just as safe as current practice, since either ongoing seizures or receiving too much midazolam can interfere with breathing. The investigators believe that a standardized seizure protocol with age-based doses is just as safe as current practice, since the seizures may stop faster and these doses are safely used in children in other healthcare settings. If this study demonstrates that standardized, age-based midazolam dosing is equally safe and more effective in comparison to current practice, the potential impact of this study is a shift in the treatment of pediatric seizures that can be easily implemented in ambulance services across the United States and in other parts of the world.

This study will expand the types of pediatric cancers being evaluated for response to cabozantinib. The current COG study is restricted to Ewing sarcoma, osteosarcoma, rhabdomyosarcoma, Wilms tumor, and a handful of uncommon tumors. The proposed study will extend this evaluation to tumors that have been shown to either express known targets of cabozantinib or with preclinical evidence of efficacy, including specifically neuroblastomas. These tumors have high morbidity and mortality, particularly in the relapse setting, and few or no proven therapeutic options. As such, evaluation of cabozantinib in these studies is warranted. The study hypothesizes that use of cabozantinib in patients with ultra-high-risk pediatric solid tumors with minimal disease burden, as defined in the inclusion criteria below, can prevent and/or slow recurrent tumor formation in pediatric solid tumors and thereby significantly extend the period of disease control and/or induce a durable cure.

OBOE is a prospective, pilot, parallel group RCT with the overall aim of examining the effect of a single dose of anti-IgE (omalizumab) vs. placebo administered at the onset of URIs in the fall season among highly exacerbation-prone, urban, and atopic youth aged 6-17 years with persistent asthma. OBOE will recruit and randomize participants over 3 years (3 annual cohorts of participants). Recruitment for each of the yearly cohorts of OBOE will begin in February. Each cohort will be followed for a 2-6-month run-in period with the objective to gain control of each participant's asthma and to stabilize the required controller medication step level. Participants will receive routine asthma care every 1-2 months (a total of 2-4 times) during run-in using a previously described algorithm developed by the Inner-city Asthma Consortium and successfully employed in the PROSE study. The primary outcome is the change in the amount of nasal IFN-α recovered by nasal fluid absorption between two time points, within 72 hours of onset of a URI as defined by onset of (or substantial worsening of) rhinorrhea, nasal congestion or sneezing (single or multiple symptoms) and 3-6 days after study drug injection.

Background: Genetic testing called "sequencing" helps researchers look at DNA. Genes are made of DNA and are the instructions for our bodies to function. We all have thousands of genes. DNA variants are differences in genes between two people. We all have lots of variants. Most are harmless and some cause differences like blue or brown eyes. A few variants can cause health problems. Objective: To understand the genetics of immune disorders various health conditions, as well as outcomes of clinical genomics and genetic counseling services performed under this protocol. Eligibility: Participants in other NIH human subjects research protocols - either at the NIH Clinical Center (CC) or at Children s National Health System (CNHS) - (aged 0-99 years), and, in select cases, their biological relatives Design: Researchers will study participant s DNA extracted from blood, saliva, or another tissue sample, including previously collected samples we may have stored at the NIH. Researchers will look at participant s DNA in great detail. We are looking for differences in the DNA sequence or structure between participants and other people. Participants will receive results that: - Are important to their health - Have been confirmed in a clinical lab - Suggest that they could be at risk for serious disease that may affect your current or future medical management. Some genetic information we return to participants may be of uncertain importance. If genetic test results are unrelated to the participant s NIH evaluations, then we will not typically report: - Normal variants - Information about progressive, fatal conditions that have no effective treatment - Carrier status (conditions you don t have but could pass on) The samples and data will be saved for future research. Personal data will be kept as private as possible. If future studies need new information, participants may be contacted....
