1. Clinical and Basic Investigations into Congenital Disorders of Glycosylation

   Rochester, Minn., Jacksonville, Fla.

   The purpose of this study is to establish the prevalence and severity of specific morbid indicators of disease severity such as specific organ system involvement, degree of cognitive disability, and case-fatality associated with various congenital disorders of glycosylation (CDG), and establish a dynamic platform to effectively disperse clinically relevant findings to families, non-expert clinicians and researchers, as well as provide a verified method to link these individuals to experts in CDG.

    

2. T Cell Response to COVID19 Vaccinated Individuals

   Rochester, Minn., Jacksonville, Fla.

   The first aim of this study is to verify that the TCR beta sequencing and curation platforms we will be using are able to identify patients with severe COVID-19 based on the TCR repertoires. This may be accomplished by testing and analyzing results between two cohorts: patients presenting acutely to MCF with mild COVID-19 and patients presenting with severe COVID-19. This will be accomplished by utilizing the the immunoSEQ Human T-cell Receptor Beta (hsTCB) Assay (Adaptive Biothechnologies) and the publicly available ImmuneCODE Open Access Database to confirm previously published data (PMID: 34253751). Both procedures will be performed by the company that created both platforms, Adaptive Biothechnologies.

   The second aim of this study is to sequence the TCR receptors of participating patients and identify TCR motifs that may indicate a predisposition to (or protection from) severe SARS-CoV-2, leading to possible risk stratification of such patients, and whether or not age, gender or ethnicity has any contribution to said risk. This may require that we examine all three cohorts listed in the Subject Information section.

   The third aim is to measure SARS-CoV-2 anti-spike and anti-nucleocapsid antibodies to distinguish patients that have not been exposed to SARS-CoV-2 to those that have been exposed.

3. Study to Analyze the Metabolic Environment in Preventing Atopic Dermatitis

   Rochester, Minn.

   The purpose of this study is to compare the assessment of the composition of the fecal, nasal,oral and skin microbiota in patients with AD (cases) as compared to age/sex and diet matched control children without atopic dermatitis, and to apply mass-spectrometry-based metabolomic approach to analyzing fecal, nasal, oral and skin samples from cases, in order to characterize their biochemical metabolic profiles by comparison with those of their controls.

4. Bioengineered Cardiac Tissue for Hypoplastic Left Heart Syndrome Analysis

   Rochester, Minn.

   The purpose of this study is to produce and characterize patient-specific cardiac tissue for Hypoplastic Left Heart Syndrome (HLHS) using reprogrammed cell technology.

5. Prospective Identification of Long QT Syndrome in Fetal Life

   Rochester, Minn.

   The postnatal diagnosis of Long QT Syndrome (LQTS) is suggested by a prolonged QT interval on 12 lead electrocardiogram (ECG),a positive family history and/or characteristic arrhythmias and confirmed by genetic testing.  LQTS testing cannot be performed successfully before birth as   fetal ECG is not possible and direct measure of the fetal QT interval by magnetocardiography is limited. Genetic testing can be performed in utero, but there is risk to the pregnancy and the fetus. Although some fetuses present with arrhythmias easily recognized as LQTS (torsade des pointes (TdP) and/or 2° atrioventricular (AV) block, this is uncommon, occurring in <25% of fetal LQTS cases. Rather, the most common presentation of fetal LQTS is sinus bradycardia, a subtle rhythm disturbance that often is unappreciated to be abnormal. Consequently, the majority of LQTS cases are unsuspected and undiagnosed during fetal life, with dire consequences. For example, maternal medications commonly used during pregnancy can prolong the fetal QT interval and may provoke lethal fetal ventricular arrhythmias. But the most significant consequence is the missed opportunity for primary prevention of life threatening ventricular arrhythmias after birth because the infant is not suspected to have LQTS before birth. The over-arching goal of the study is to overcome the barriers to prenatal detection of LQTS. The investigators plan to do so by developing an algorithm using fetal heart rate (FHR) which will discriminate fetuses with or without LQTS. Immediate Goal: The investigators propose a multicenter pre-birth observational cohort study to develop a Fetal Heart Rate (FHR)/Gestational Age (GA) algorithm from a cohort of fetuses recruited from 13 national and international centers where one parent is known by prior genetic testing to have a mutation in one of the common LQTS genes: potassium voltage-gated channel subfamily Q member 1 (KCNQ1), potassium voltage-gated channel subfamily H member 2 (KCNH2), or sodium voltage-gated channel alpha subunit 5 (SCN5A). The investigators have chosen this population because 1) These mutations are the most common genetic causes of LQTS, and 2) Offspring will have high risk of LQTS as inheritance of these LQTS gene mutations is autosomal dominant. Thus, progeny of parents with a known mutation are at high (50%) risk of having the same parental LQTS mutation. The algorithm will be developed using FHR measured serially throughout pregnancy. All offspring will undergo postnatal genetic testing for the parental mutation as the gold standard for diagnosing the presence or absence of LQTS.

6. A Study of Noninvasive Hemoglobin Monitoring in Pediatric Patients Undergoing Orthopedic Surgery

   Rochester, Minn.

   The purposes of this study are to validate noninvasive hemoglobin monitoring in postoperative orthopedic pediatric patients, to evaluate patient, parent, and provider preference of noninvasive hemoglobin monitoring compared to invasive blood draw, and to evaluate cost effectiveness of noninvasive monitoring in comparison to invasive blood draws.

7. A Study to Evaluate Bleomycin, Carboplatin, Etoposide, or Cisplatin in Treating Pediatric and Adult Patients with Germ Cell Tumors

   Rochester, Minn.

   The purpose of this study is to evaluate how well bleomycin, carboplatin, etoposide, or cisplatin work in treating pediatric and adult patients with germ cell tumors. Active surveillance may help doctors to monitor subjects with low risk germ cell tumors after their tumor is removed. Drugs used in chemotherapy, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

8. Transforming Healthcare and Outcomes for Children with Inflammatory Bowel Disease

   La Crosse, Wis., Mankato, Minn., Rochester, Minn., Eau Claire, Wis.

   The purpose is to put the information into a very large database, which can then be used to improve patient care and achieve the best health outcomes possible for children with IBD.

9. Study of the Incidence of Electrographic Status Epilepticus and Seizures of PICU Patients at National Children’s Hospital in Hanoi, Vietnam.

   Rochester, Minn.

   The purpose of the study is:

   1. To determine the incidence of subclinical electrographic seizures and electrographic status epilepticus in children admitted to the PICU for head trauma, traumatic brain injury (TBI), and/or child abuse at National Children’s Hospital in Hanoi, Vietnam.

   2. To determine whether a correlation exists between length of stay, morbidity, and mortality with incidence of subclinical SE and seizures.

10. Long-Term Follow-Up of Patients Who Have Participated in Children's Oncology Group Studies

    Rochester, Minn.

    This clinical trial is studying long-term follow-up in patients who are or have participated in Children's Oncology Group studies. Developing a way to track patients enrolled in Children's Oncology Group studies will help doctors gather long-term follow-up information and may help the study of cancer in the future.
