Women who develop preeclampsia during pregnancy are more likely to develop and die of cardiovascular disease later in life, even if they are otherwise healthy. The reason why this occurs is unclear but may be related to impaired endothelial function and dysregulation of the angiotensin system that occurs during the preeclamptic pregnancy and persists postpartum, despite the remission of clinical symptoms. The purpose of this investigation is to determine the mechanisms contributing to this lasting blood vessel damage caused by reduced endothelial function in women who have had preeclampsia compared to women who had a healthy pregnancy. Identification of these mechanisms and treatment strategies may lead to better clinical management of cardiovascular disease risk in these women. The purpose of this study is to examine the microvascular differences in women who have had preeclampsia following activation of protective angiotensin receptors in the skin. This will help increase understanding of the mechanisms of angiotensin II receptors in these women, and how activation of these receptors may restore microvascular function. In this study, the investigators use the blood vessels in the skin as a representative vascular bed for examining mechanisms of microvascular dysfunction in humans. Using a minimally invasive technique (intradermal microdialysis for the local delivery of pharmaceutical agents) the investigators examine the blood vessels in a dime-sized area of the skin.

This cluster randomized controlled trial will evaluate a community-based bicycle safety education program with and without an in-person parent training component. The investigators will recruit 180 early adolescent bicyclists (ages 9 to 12) and a parent/guardian from local neighborhood centers after school and summer programs, where the investigators have conducted preliminary studies. Randomization into the three study groups will occur at the site-level. Adolescent bicycles in all study group sites will be equipped with Pedal Portal, an innovative bicycle-mounted GPS/video system developed by the research team to objectively observe bicycling risk exposure and behaviors while bicycling. System data will be coded to measure bicycling exposure (hours, miles traveled, routes) and the types and rates of safety-relevant events (near crashes, crashes), and safety-relevant behaviors (e.g., following traffic rules, scanning for traffic at intersections). This will be the first randomized trial to use GPS and video technology to evaluate the effectiveness of a youth bicycle safety intervention in changing behavior. The control group will not receive any bicycle safety education programming. Participants in the first intervention group (Bike Club) will receive a 12-hour bicycle safety education program. Participants in the second intervention group (Bike Club Plus) will receive an enhanced version of the 12-hour bicycle safety education program which will include a parent training session on bicycling safety best practices, child development as it relates to bicycling, strategies for practice at home, and feedback on their adolescent's bicycling performance. The investigators' main hypotheses are that adolescents who receive the bicycle safety intervention will have increased safety behaviors (e.g., helmet use, hazard recognition), reduced errors (e.g., riding against traffic, swerving/wobbling), and increased knowledge, perceptions, and self-efficacy compared to the control group; and adolescents whose parent receives the parent training will have even greater improvements in study outcomes than those whose parents do not receive the training. If successful, approaches from this study could be widely implemented to improve adolescent bicycling safety. Read Less

The goal of the Tiny Baby Collaborative Multicenter Inventory of Neonatal-Perinatal Interventions (MINI) minimum dataset is to serve as a registry detailing the outcomes and practices for all deliveries and infants admitted to intensive care at 22-23 weeks' gestation at participating hospitals.

The current study is a randomized multi-center clinical trial that investigates the role an intraoperative hearing monitoring system (electrocochleography) has on helping to save residual hearing in patients undergoing cochlear implantation (CI). Read Less

This phase III trial compares the combination of four drugs (daratumumab, bortezomib, lenalidomide and dexamethasone) to the use of a three drug combination (daratumumab, lenalidomide and dexamethasone). Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Daratumumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Anti-inflammatory drugs, such as dexamethasone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Adding bortezomib to daratumumab, lenalidomide, and dexamethasone may be more effective in shrinking the cancer or preventing it from returning, compared to continuing on daratumumab, lenalidomide, and dexamethasone.

This phase II/III trial compares the effect of adding chemotherapy before and after surgery versus after surgery alone (usual treatment) in treating patients with stage II-III gallbladder cancer. Chemotherapy drugs, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy before surgery may make the tumor smaller; therefore, may reduce the extent of surgery. Additionally, it may make it easier for the surgeon to distinguish between normal and cancerous tissue. Giving chemotherapy after surgery may kill any remaining tumor cells. This study will determine whether giving chemotherapy before surgery increases the length of time before the cancer may return and whether it will increase a patient's life span compared to the usual approach.

This phase II trial investigates how well biomarkers on PET/CT imaging drive early discontinuation of anti-PD-1 therapy in patients with stage IIIB-IV melanoma that cannot be removed by surgery (unresectable). Anti-PD-1 therapy has become a standard therapy option for patients with unresectable melanoma. This trial is being done to determine if doctors can safely shorten the use of standard of care anti-PD1 therapy for melanoma by using biomarkers seen on PET/CT imaging and tumor biopsy. Read Less

The purpose of this study is to compare the two approaches for monitoring pancreatic cysts. The study doctors want to compare more frequent monitoring vs less frequent monitoring in order to learn which monitoring method leads to better outcome for patients with pancreatic cysts. Read Less

This phase II trial studies how well lower-dose chemotherapy plus radiation (chemoradiation) therapy works in comparison to standard-dose chemoradiation in treating patients with early-stage anal cancer. Drugs used in chemotherapy, such as mitomycin, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy with radiation therapy may kill more tumor cells. This study may help doctors find out if lower-dose chemoradiation is as effective and has fewer side effects than standard-dose chemoradiation, which is the usual approach for treatment of this cancer type.

This phase III trial studies how well lenalidomide and dexamethasone works with or without daratumumab in treating patients with high-risk smoldering myeloma. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and dexamethasone with daratumumab may work better in treating patients with smoldering myeloma. Read Less
