Subjects in the first group will be enrolled in the GM-CSF for Reversal of Immunoparalysis in Pediatric Sepsis-induced MODS (GRACE-2) trial, comparing GM-CSF versus placebo. Subjects in the second group will be an observational cohort with no intervention, because this group has very low mortality and morbidity. Subjects in the third group will be enrolled in the Targeted Reversal of Inflammation in Pediatric Sepsis-induced MODS (TRIPS) trial, comparing anakinra and placebo. The fourth group, with very severe inflammation,
will be an observational cohort because clinical management of the inflammation
is standard of care, and there is no equipoise about enrolling these children in a placebo controlled trial. The primary outcome of both trials will be duration and severity of organ dysfunction using the cumulative PELOD-2 score, and secondary outcomes will assess health related quality of life and family functioning at 3 and 12 months.

Hematopoietic cell transplantation (HCT) and solid organ transplantation (SOT) recipients are at high risk for respiratory viral infection (RVI). This study aims to establish a comprehensive RVI diagnostic and disease progression predictive model in children undergoing HCT and SOT. Findings will result in the first ever evidence-based pediatric guidelines.

This study is an open label, Comparative Effectiveness Research study in patients who receive a heart transplant. Subjects will be enrolled into the study while under evaluation for heart transplantation or on the transplant waiting list prior to heart transplantation. All subjects will follow the center's standard of care surveillance schedule from transplant through 4 weeks post-transplantation. The study objective is to compare the effectiveness of rejection surveillance of heart transplant recipients with Prospera dd-cfDNA to rejection surveillance with endomyocardial biopsy (EMB) in the first post-transplant year.
The Prospera™ test is a non-invasive test intended to detect and quantify the fraction of donor-derived cell-free DNA (dd-cfDNA) to supplement management and surveillance of allograft rejection in patients who have undergone organ transplantation. The subjects may undergo blood draws, echocardiogrphys, medical history and physical exams, antibody testing, nuclear imaging, and MRI as apart of the study. The study period will be during the first 12 months post-transplant. Quality of life questionnaires will be completed at week 4, month 6 and month 12 post-transplant.

Examine current real-world utilization of mcfDNA using a multi-center retrospective registry. To achieve this aim, we will utilize a multi-center REDCap database to examine and summarize patient demographics and types of transplants where mcfDNA was used. We will classify cases based on common syndromes/indications for which mcfDNA is sent, timing of the test, and clinically relevant microbiologic yield of mcfDNA results.

Identify clinical predictors where mcfDNA outperforms CMT. We will analyze specific clinical syndromes where mcfDNA has higher yield compared to CMT including pneumonia, visceral abscesses, CNS infections, etc. We will also
identify specific pathogens that are more likely to be detected by mcfDNA earlier in the clinical course such as bartonella, syphilis, parasitic infections, and other atypical bacteria, mycobacteria, and fungi.

Analyze clinical impact of mcfDNA to assess whether the use of the test had a positive vs. negative vs. neutral impact on patient care using pre-specified definitions. Additionally, we will perform clinical adjudication of positive and
negative mcfDNA cases using standardized criteria and analyze effect of timing of test ordering on clinical impact.

The long-term objective of this proposed R24 program is to enhance our understanding of how circadian rhythm disruption contributes to vulnerability to alcohol-induced organ damage, and to explore the underlying mechanisms (e.g. microbiota) that could lead to the identification of novel therapeutic targets. This knowledge aims to inform the development of innovative strategies to prevent and to treat alcohol-related pathologies.

This study is testing a new medicine called Visugromab (CTL-002) to see if it helps people with a type of lung cancer called metastatic non-squamous non-small cell lung cancer. Everyone in the study will get standard cancer treatment, but some will also get Visugromab while others get a placebo (a look-alike with no active drug), and who gets what is decided randomly—like flipping a coin. The goal is to find out if Visugromab makes the treatment more effective and safe. The study will last up to two years, with Treatment in cycles lasting 3 weeks, about once a month. Researchers will closely monitor participants to see how well the treatment works and how their bodies respond. Serious risks of treatment may include heart problems, low oxygen levels, infections, organ failure, and inflammation in various parts of the body such as the lungs, liver, intestines, pancreas, and thyroid.

Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of organ dysfunction, usually occurring after 20 weeks of pregnancy. It can lead to serious health problems for both the pregnant person and the baby. Although some risk factors for preeclampsia are known, effective strategies to prevent the condition remain limited.

The purpose of this research study is to determine whether vaginal progesterone can help prevent preeclampsia in pregnant individuals. Progesterone is a hormone that is naturally produced during pregnancy and is already used for certain pregnancy-related conditions.

Participants who choose to join the study will be randomly assigned (by chance, like flipping a coin) to receive either vaginal progesterone or no medication. Participants will use the study medication as directed during pregnancy and will continue to receive their routine prenatal care.

Researchers will collect information from prenatal visits, medical records, and delivery outcomes to determine whether progesterone reduces the risk of developing preeclampsia and improves pregnancy outcomes. The information gained from this study may help identify a safe and effective way to prevent preeclampsia and improve the health of pregnant individuals and their babies in future pregnancies.
