This study is evaluating the impact of prenatal sequencing on the management of fetuses with ultrasound abnormalities. The hypothesis is that a significant subset of fetal abnormalities have a genetic cause that can be identified by sequencing and that prenatal knowledge of this information will improve prenatal care, reduce unnecessary diagnostic testing, reduce the cost of care, and improve the quality of life for both the child and the family.

This study investigates molecular and physical biomarkers of headaches in order to better understand mechanisms of these diseases. There are 3 main parts: 1. Use of capsaicin (active ingredient in hot chili peppers) to trigger release of calcitonin gene related peptide - the hypothesis is that this will be different in headache subjects compared to controls (and if so might be used to predict how these patients will respond to certain medications that modulate calcitonin gene-related peptide). Subjects will be given capsaicin as a cream applied to the forehead or the inner nostril, or a hot sauce that is ingested. 2. Use of capsaicin to trigger eye watering - the hypothesis is that oxygen gas will slow down the amount of eye watering. Cluster headache patients respond very powerfully to oxygen gas but to very little else. The mechanism for oxygen is unknown but in rodents there is data that it works on the parasympathetic / lacrimal gland system. This study translates rodent data into humans in a non-invasive way to confirm the mechanism of this very effective treatment. 3. Use of ice water to trigger headaches - brain freeze causes a very short-lived but intense headache that may cause similar biomarker release as other headache disorders. This may be a useful human model for other headache disorders.

In order to expand neuroscience research and move laboratory advances to patients, there is a need to integrate reliable clinical data with biologic information from patient tissue specimens. The Neuroscience Research Repository (NRR) seeks to meet this need. The NRR is a prospective database and sample bank created to collect information and samples for current and future neuroscience research. The objective of this NRR is to develop a data and sample repository for study of neurological conditions. A repository utilizing standardized electronic health data and samples collected in a uniform manner serves to foster the ability to perform research on current and future projects. Samples and data for clinical, genomic and proteomic analysis will be provided to optimize their value for neuroscience research. The NRR will enroll patients and collect clinically recorded longitudinal data for as long as they are followed by the Neurosurgery service and up to an additional 5 years after being released from care. Patients will be enrolled on admission to the service and samples will be taken at three time points: Time One, within 24 hours of event (preferably first blood draw); Time Two, within 48 hours of event; and Time Three, time of any residual tissue availability. Family members of select groups of patients will also be approached for enrollment. Samples and data will be labeled with a study code to maintain confidentiality. Samples and data will be maintained in secure, limited access environments with back-up/redundancy procedures in place. Sample inventory will be maintained with a bar-coding system. A duty to warn clause will be included in the consent as will the determination of willingness to be re-contacted for future research. Time of sample acquisition to time of sample processing will be documented for quality control purposes. Freezers will be monitored for temperature stability. Recipient investigators will be requested to provide feedback on sample quality. Samples will be distributed to neuroscience investigators after approval from the Neurosurgery Scientific Review Committee - Dissemination Review Committee and the Committee for the Protection of Human Subjects (CPHS).

The goal of this clinical trial is to compare an active intervention versus a standard of care control in reducing alcohol use among pregnant women. The main questions it aims to answer are whether a motivational intervention can: 1. increase the proportion of women detected with a laboratory-confirmed negative phosphatidylethanol (PEth) test during pregnancy, and 2. reduce the proportion of adverse birth outcomes among infants. Participants will be offered (1) a self-paced computer-delivered alcohol reduction intervention to enhance knowledge, norms, and motivation for alcohol reduction and (2) a nurse-delivered component to reinforce the computer-delivered content and address women's questions. Both components are theory-driven, based on Motivational Enhancement Theory (MET), and use motivational strategies to promote alcohol reduction.

Early pregnancy renal anhydramnios or EPRA is a condition where a pregnant woman does not have any amniotic fluid around her fetus because of a problem with the fetus's kidneys. This condition is thought to be fatal once the fetus is born because of inadequate lung growth. The Renal Anhydramnios Fetal Therapy (RAFT) Trial offers eligible pregnant women with a diagnosis of EPRA an experimental therapy of repeated or serial "amnioinfusions" of fluid into the womb. An amnioinfusion involves placing a small needle through the pregnant woman's skin into the womb next to the fetus. Warm sterile fluid with balanced electrolytes and antibiotics is then slowly infused into amniotic space inside the womb. The aim is to help the fetus's lungs grow enough so he or she can survive after birth. These amnioinfusions will be carried out by an expert in fetal interventions at a RAFT center. There is a significant risk of early rupture of membranes and early delivery in subjects who receive amnioinfusions, and any potential trial participants will be counseled about these risks before they decide whether to join the trial. Any eligible patients who, after counseling, elect to terminate the pregnancy will not be eligible to participate in the trial. All eligible patients who choose to join the RAFT trial will be able to choose their assignment into one of two arms of the study: (1) to receive serial amnioinfusions (2) to not receive amnioinfusions but receive monitoring for the remainder of the pregnancy at the RAFT center. Thus, assignment of patients to study arm will not be random, but will be decided by the participant. Fetuses who do survive after birth will require intensive medical management for kidney failure including placement of a dialysis catheter and dialysis therapy with the eventual need for a kidney transplant. Treatment for lung disease secondary to abnormal lung development may also be required. The study will follow babies and their families until non-survival or transplant. Update: Due to recommendations from the RAFT trial Data and Safety Monitoring Board, the trial is no longer open to enrollment for pregnancies complicated by bilateral renal agenesis as of July 19, 2022. Enrollment for patients with pregnancies complicated by other causes of fetal renal failure remains open.

Biomarkers for Vascular Contributions to Cognitive Impairment and Dementia (MarkVCID) is an NIH-funded consortium dedicated to finding biomarkers involved in age-related thinking and memory problems. Alzheimer's disease and other dementias leave signatures on brain scans or in the blood called biomarkers. The MarkVCID study will measure a panel of candidate biomarkers in 1800 participants and watch them closely to see what they tell us about changes in brain function and risk of memory loss. Age-related problems in thinking and memory represent some of the greatest risks to public health in the US and globally. Diseases that affect small blood vessels in the brain have been shown to be major contributors to these changes. However, research and patient care can be held back by limited biomarkers that identify who should be treated. The MarkVCID Consortium includes 17 US medical centers, a Coordinating Center, an External Advisory Committee, and NIH leadership. Data and biospecimens collected as part of this research study will be stored in a research database and biorepositories, so that researchers can use this information to study brain function.
