Do you have overweight or obesity and normally sleep between 10 pm and 3 am? This study is investigating how sleep schedules and circadian rhythm misalignment can contribute to increased consumption of energy dense/prepared foods and to decreased insulin sensitivity, which can raise a person's risk of cardiometabolic risk factors. This study is located in Salt Lake City, Utah.

Are you an adult who has idiopathic pulmonary fibrosis or an advanced lung cancer? This study aims to see whether a new imaging dye for positron emission tomography (PET) is effective at looking at fibrosis in lung cancer and idiopathic pulmonary fibrosis (IPF). Participants will be given the imaging dye and then receive a PET scan. To participate in this study, you must either be between 18 and 80 years old and have lung cancer or be a healthy volunteer or be between 50 and 80 years old and have IPF. This study is located in Boston, Massachusetts.

Are you between 40 and 85 with worsening idiopathic pulmonary fibrosis? This study aims to test a new combination treatment for acute exacerbations, a life-threatening complication of idiopathic pulmonary fibrosis (IPF) that has no approved treatment. The treatment is meant to help stop part of the immune system from further injuring the lung tissue. To participate in this study, you must be between 40 and 85 years old and have worsening IPF. This study is located in Birmingham, Alabama; Boston, Massachusetts; Philadelphia, Pennsylvania; and Pittsburgh, Pennsylvania.

Do you or your child have a platelet, bleeding, or white blood cell disorder? This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

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.
