Alzheimer's disease and related dementias lead to marked declines in daily functioning, independence, and quality of life. One of the earliest cognitive changes in these conditions is impairment in prospective memory, or the ability to remember future intentions such as taking medications at a given time. Prior intervention studies that targeted prospective memory used mnemonic strategies or cognitive training, but these approaches resulted in modest gains in clinical populations. By contrast, a Stage I pilot trial indicated that smartphone-based memory aids (reminder apps) can be accepted and used by persons with mild cognitive impairment and mild dementia to improve both subjective and objective prospective memory performance. The investigators will now test for efficacy, durability, and generalizability of benefits across diverse samples in a Stage II randomized controlled trial. Some 200 participants with mild cognitive impairment or mild dementia will be recruited, half of whom will be from digitally-disadvantaged backgrounds (low socioeconomic status, rural, or historically underrepresented groups). Participants will complete baseline assessments and then be randomly assigned to a smartphone reminder app intervention or an active control condition that uses a paper- based memory support system. Across a 4-week intervention period, participants will complete patient-selected and experimenter-assigned prospective memory assessments and receive booster training sessions to promote self-efficacy with the intervention/control system. Durability of effects will be assessed at 3-month and 6-month follow-up sessions. As a secondary aim, study partners will be simultaneously enrolled to collect informant ratings, track how much study partners assist the participants, and determine whether improving prospective memory in patients improves quality of life in study partners (e.g., by reducing the double to-do list burden of remembering for themselves and for care recipients). As a third aim, the investigators will identify barriers and facilitators to smartphone interventions in digitally-disadvantaged individuals who have historically been underrepresented in technology and dementia research.

open study

Over half of women in the US who are breastfeeding their infants take prescription drugs. You are being asked to participate in this study because you are breastfeeding your infant and are currently taking, as part of your medical care, at least one of the drugs we are studying. We are interested in studying drugs commonly prescribed to women who are breastfeeding so we can learn more about the amount of drug that is transferred to breastmilk and estimate how much of drug that is consumed by breastfed infants.

Start Date: Oct 2018

open study

The objective of this study is to investigate the hypothesis that delivery at 35 0/7- 35 6/7 weeks in stable patients with gastroschisis is superior to observation and expectant management with a goal of delivery at 38 0/7 - 38 6/7 weeks. To test this hypothesis, we will complete a randomized, prospective, multi-institutional trial across NAFTNet-affiliated institutions. Patients may be enrolled in the study any time prior to 33 weeks, but will be randomized at 33 weeks to delivery at 35 weeks or observation with a goal of 38 weeks. The primary composite outcome will include stillbirth, neonatal death prior to discharge, respiratory morbidity, and need for parenteral nutrition at 30 days.

open study

The purpose of this study is to compare organization of normal brain function as detected using Functional magnetic resonance imaging (fMRI) in normal subjects as opposed to patients with epilepsy or brain tumors, to ascribe precise anatomic labels (including Brodmann Areas) and functional significance to each region involved in cognitive processes as detected by cortical stimulation mapping (CSM) in patients with implanted subdural electrodes (SDE) or depth (sEEG) electrodes, to describe the locations of these regions in Talairach space, for a population of patients without overt structural abnormalities in these regions, to generate a spatial probability map of locations of cortical regions "essential" for these processes, to compare the loci of "crucial" language, visual, motor and cognitive sites as determined by CSM with the loci determined by a battery of tasks using fMRI for each individual and to use these data in patients undergoing intracranial electro-corticographyto determine the loci of essential, involved and uninvolved brain areas, and use sophisticated mathematical analyses of these intracranial recordings to study information flow between these areas.

The primary objective of the study is to determine the optimal intra-arterial drug treatment regimen for arterial lumen restoration post cerebral vasospasm following aneurysmal subarachnoid hemorrhage. The secondary objective is to evaluate clinical outcome at 90 days post discharge following optimal intra-arterial drug treatment for cerebral vasospasm. We hypothesize that Intra-arterial (IA) infusion of a combination of multiple vasodilators is more efficacious than single agent treatment cerebral vasospasm therapy. All procedures done as a part of this study are standard hospital care procedures done to treat cerebral vasospasm and all drugs to be used are FDA approved.
