The purpose of this study is to evaluate if adding a noninvasive testing of End Tidal Carbon Monoxide with a FDA approved device will help improve management of jaundice in the Neonates by reducing the number of lab draws, Coombs tests and optimizing the number of phototherapy hours in Neonates who need it. Eligible subjects will be Term and healthy late preterm newborns born at Cedars-Sinai Medical Center and admitted to well baby nursery from November 2020 onwards. The primary procedure of measuring an End-Tidal Carbon monoxide in a Newborn is going to be with a soft cannula applied to the Newborn's nose for a few minutes. The whole procedure will take about 15+ 5 minutes. Subject participation will last approximately 6 months and all subjects will be followed up with one phone call at about 2-4 weeks of age. Adding ETCO testing to current standard of care might reduce the number of lab draws in a newborn and potentially reduce costs by optimizing the number of phototherapy hours in a Newborn who needs it. Cedars- Sinai Medical Center will not be billing the patients for the End-Tidal Carbon Monoxide measurement for this study.
In newborns, intravascular hemolysis (the breakdown of red blood cells inside the blood vessels) can range from mild, as part of the physiological (normal) turnover of red blood cells, to severe in cases such as jaundice (an increase in bilirubin levels) Early biomarkers of haemolysis would improve neonatology (newborn) practice by identifying at-risk patients, particularly if the assay is simple, rapid, non-invasive and quantitative. Our now-completed URICA trial on full-term male babies showed that the small cytoplasmic protein carbonic anhydrase I (CAI), found abundantly in red blood cells, was detected in 17 out of 26 urine samples collected once per recruited baby at the neonatology ward. CAI-positive samples were obtained from babies with levels of bilirubin that were rapidly rising or peaking above the threshold for phototherapy. CAI-negative urine was obtained when either bilirubin did not reach phototherapy (a light treatment used for excessive jaudice) threshold, or after it had recovered from its peak. On four occasions, the cause of CAI-positive urine was undetermined. Since CAI is normally absent from urine, a positive signal is indicative of intravascular hemolysis and confirms that CAI crossed the glomerular barrier (a barrier within the kidneys that filters large molecules). However, the quantitative power of urinary CAI to predict and estimate an impending haemolytic crisis requires a new longitudinal study, which is the objective of the URICA-II trial. The URICA-II trial would recruit 30 full term newborn infants delivered at the Evelina London Children's Hospital. The babies recruited would be expected to stay in the hospital for at least 5 days due to treatment for jaundice, infection or some other condition. Participants will have daily non-invasive (bag) urine samples collected and daily transcutaneous (skin) bilirubin levels recorded upto 10 days. The study will last upto 2 years.
Use HeprAN ™ membrane (coated with heparin) should be allow the success of dialysis sessions, with adequate dialysis parameters, in patients treated by long-term anticoagulation with VKA, without addition of heparin perdialytic. Less use of heparin (UFH or LMWH) during hemodialysis session should be allow a decrease of bleedings (moderate or major) and blood transfusions for hemodialysed patients with HeprAN ™ membrane and treated by long-term anticoagulation with VKA
Temporary mechanical circulatory support devices are increasingly used for short-term support in patients with decompensated cardiogenic shock. Recently, a new axial flow pump has become widely available with the Impella System. The Impella has been FDA approved for short term usage. Hemolysis, however, has been a common complication that has increased morbidity and mortality in this patient population. It is hypothesized that a major source of hemolysis in this patient population is shear stress experienced by red blood cells (RBC) as they travel through the pump device. In addition to causing RBC loss and potential anemia, the hemolysis has multiple other downstream consequences including creation of a pro-thrombotic environment leading to clot formation and potential device failure and secondary end organ dysfunction (renal and liver failure). Due to the significant effects of hemolysis in this population, a great deal of interest has been recently focused on addressing this problem, but as of yet no durable solutions exist. Pentoxifylline improves red blood cell deformability and reduces blood viscosity. It is hypothesized here that administering Pentoxifylline to patients in CS who require temporary MCS will decrease the amount of shear stress related hemolysis through the improved deformability and durability of RBCs. We propose to perform a double-blinded randomized controlled trial in patients who undergo an axillary Impella 5.0 insertion for acute decompensated heart failure. There will be a control group who receives a placebo and the treatment group who receives pentoxifylline. Labs will be drawn to monitor hemolysis which is our current standard protocol for the life of the device to determine the efficacy of pentoxifylline in decreasing hemolysis in this patient population.
Diarrhea-associated hemolytic uremic syndrome (D+HUS) is defined as a prodrome of enteritis followed by thrombocytopenia (< 150,000/mm3), microangiopathic hemolytic anemia, and signs of variable degrees of renal damage (increase in serum Cr, proteinuria, and/or hematuria) . Our aim is to detect the most reliable early predictors of poor prognosis to identify children at major risk of bad outcome who could eventually benefit from early specific treatments.
