The purpose of this study is to find out if pulsed dye laser treatment or timolol maleate 0.5% gel can help infants who have a hemangioma. The investigators also want to find out if pulsed dye laser treatment and timolol maleate 0.5% gel are safe to use without causing too many side effects. Hemangioma is a common type of birthmark. These birthmarks happen when many new blood vessels grow in a specific area on the skin. Blood vessels are tiny tubes that carry blood through the body. No one knows what causes blood vessels to group together. Most birthmarks don't hurt at all and they usually aren't a sign of any kind of illness. Lots of newborns have these birthmarks on their bodies, like between the eyebrows. These birthmarks usually disappear within the first few months to years of life. These birthmarks tend to disappear spontaneously. Most hemangiomas are not treated unless the hemangioma threatens the child's health, which occurs in about 1 in 3 children with hemagiomas. Pulsed dye laser is widely used in children, and is approved by the U.S. Food and Drug Administration (FDA) for treating hemangioma. The FDA has approved timolol maleate to treat glaucoma in adults, but the FDA has not approved timolol maleate to treat hemangiomas in children. About 7 infants with hemangiomas have received timolol maleate. The results so far show that timolol maleate may be helpful and safe in treating hemangiomas in infants. An important question being tested in this study is whether pulsed-dye laser or timolol maleate can prevent hemangioma from growing when used very early after birth.

The goal is to look for qualitative differences in visual search behavior when one search is performed many times in a row compared to when multiple search tasks are intermixed. Four search tasks are tested. The target is the same in every task but the types of distractors change from task to task. In this version, observers get some degree of choice in what they are searching.

This phase III trial compares the effect of adding tivozanib to standard therapy pembrolizumab versus pembrolizumab alone for the treatment of patients with high-risk renal cell carcinoma (RCC). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Tivozanib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals tumor cells to multiply. This helps stop the spread of tumor cells. Giving pembrolizumab and tivozanib together may work better than pembrolizumab alone in treating patients with RCC.

The goal of this observational study is to learn about burnout and workplace violence among frontline clinicians working in Home Hospital programs compared with traditional brick-and-mortar hospitals. The main questions it aims to answer are: 1. Do Home Hospital clinicians experience different levels of burnout than clinicians working in traditional inpatient hospital settings? 2. Do Home Hospital clinicians experience different rates of workplace violence and harassment than clinicians working in traditional inpatient hospital settings? Researchers will compare clinicians working primarily in Home Hospital settings with clinicians working primarily in brick-and-mortar hospitals to assess differences in burnout, workplace safety, and work experience. Participants will: - Complete a one-time anonymous online survey through REDCap. - Answer questions about their demographic and professional background. - Complete validated questionnaires assessing burnout, workplace safety culture, and experiences with workplace violence or harassment. - Provide optional free-text feedback about their work experience.

The goal of this clinical trial is to assess the efficacy of ivonescimab monotherapy in patients with advanced non-small cell lung cancer harboring actionable genomic alterations who have received prior targeted therapies and chemotherapy. This clinical trial also aims to assess the efficacy of ivonescimab plus carboplatin/pemetrexed chemotherapy in patients with advanced non-small cell lung cancer harboring actionable genomic alterations other than epidermal growth factor receptor mutations who have received prior targeted therapies but no chemotherapy. The main questions it aims to answer are: - Will ivonescimab alone or together with carboplatin/pemetrexed chemotherapy shrink tumors in the clinical trial's patients? - Will ivonescimab alone or together with carboplatin/pemetrexed chemotherapy effectively influence if the patients' cancer grows, how long the treatment takes to start working, how long the treatment keeps working after it first starts to help, how long the treatment keeps the cancer from getting worse, and overall survival of patients? - How many patients receiving ivonescimab alone or together with carboplatin/pemetrexed chemotherapy will experience treatment-emergent, treatment-related, immune-related, and especially interesting side effects? Patients receiving ivonescimab alone will receive an intravenous infusion of ivonescimab every 3 weeks for up to 24 months. Patients receiving ivonescimab together with carboplatin/pemetrexed chemotherapy will receive separate intravenous infusions of ivonescimab, pemetrexed, and carboplatin every 3 weeks for 4 cycles (each cycle is 21 days). These patients will continue to receive infusions of ivonescimab and pemetrexed every 3 weeks for up to 24 total months.
