Does your infant have a low platelet count? This study is investigating the safety and efficacy of platelet transfusion as a treatment for infants with thrombocytopenia. Researchers are looking at the positive effects of platelet transfusion against the negative effects, such as the release of inflammatory molecules and the formation of blood clots. To participate in this study, your child must be younger than 6 months old and have a low platelet count (less than 100 × 109/L). This study takes place in Boston, Massachusetts.

Does your infant have a low platelet count? This study investigates immature platelet counts as a marker for bleeding risk in newborns with thrombocytopenia, compared with platelet counts alone. Immature platelets are the most recently produced platelets and may be a better marker of platelet production. To participate in this study, you must have a newborn who is less than 32 weeks’ gestational age, has a birth weight greater than 500 grams, and has a platelet count less than 100 × 109/L. This study takes place in multiple locations in the United States, the Netherlands, and Sweden.

Are you a Minnesota resident with hypertrophic cardiomyopathy? This study aims to find out how common it is for people with hypertrophic cardiomyopathy to also have sleep apnea. Hypertrophic cardiomyopathy is a disease that causes the heart muscle to thicken. Participants will also wear a heart rhythm monitor to help researchers learn whether sleep apnea is linked to arrhythmia. The study seeks healthy volunteers as well as participants in the Hypertrophic Cardiomyopathy Registry. To participate in this study, you must not have had a catheter ablation procedure to treat atrial fibrillation, had surgery to replace your heart valves, or been treated for sleep apnea. The study is located in Rochester, Minnesota.
