The goal of this proposal is to prospectively collect data from a series of 100 patients (all ages) undergoing complex cardiac surgical procedures involving cardiopulmonary bypass (CPB) to: 1. Measure the number of blood activated circulating monocytes before, during and after cardiac surgery and serum GABA and pro-inflammatory cytokine levels 2. Understand the correlation between GABA and inflammatory cytokines (and/or activated monocytes) and 3. Assess the correlation between thrombosis and monocyte activation in patients undergoing cardiac surgery under CPB and at risk of thrombosis. Read Less

Surgical site infections (SSIs) are one of the major hospital acquired infections and responsible for the most cost among the hospital acquired infections. The objective of this study is to assess the neutrophil functional profiles and their associations with SSIs. Read Less

Anemia is common during pregnancy due to increased metabolic rate and normal physiologic changes associated with pregnancy. Anemia during pregnancy has been associated with increased of adverse outcomes during delivery and the postpartum period. Currently, it is recommended to screen for anemia at three pre-specified points during routine prenatal care, typically 3 months apart. This screening method may miss patients who develop anemia between these intervals and lead to a delay in diagnosis and treatment. MasimoTM has developed a non-invasive device that can detect anemia without a blood draw. This device has not been extensively studied in pregnant patients. The aim of this study is to determine the agreement in hemoglobin readings between the non-invasive device and the standard of care blood draws in pregnant patients. Read Less

The researchers are doing this study to find out whether the combination of ruxolitinib and ulixertinib is a safe and effective treatment for people with myelofibrosis. The researchers will test different doses of ulixertinib to find the highest dose that causes few or mild side effects in participants when given in combination with ruxolitinib. Read Less

The overall goal of this study is to determine whether a novel, multi-modal, patient-directed behavioral intervention initiated in rheumatology clinics is an effective approach to improve uptake of updated COVID-19 vaccine. Read Less

Alzheimer's disease (AD) is characterized by significant memory loss, toxic protein deposits (amyloid and tau) in the brain, and changes in the gamma frequency band on EEG. Gamma waves are important for memory, and in patients with AD, there are fewer gamma waves in the brain. The Tsai lab found that boosting gamma waves in AD mouse models using light and sound stimulation at 40Hz not only reduced amyloid and tau in the brain, but also improved memory. A light and sound device was developed for humans that stimulates the brain at 40Hz that can be used safely at home. The goal of this study is to see if using this device can prevent dementia in people who are at risk for developing Alzheimer's disease. Read Less

The goal of this study is to test the effects of just-in-time intervention strategies aimed to promote implementation of the safety plan and its components at different levels of suicidal urges and intent. The main questions the investigators aim to answer are: 1. What is the acceptability and feasibility of the just-in-time intervention strategies? 2. What are the proximal effects of just-in-time intervention strategies aimed to promote use of the safety plan and its components? 3. What internal and external contextual factors moderate the just-in-time intervention effects? Participants (adults hospitalized for suicidal thoughts or behaviors) will: * Answer questions about current suicidal thoughts on their smartphone up to 4 times each day during both hospitalization and the 4 weeks after they leave the hospital * Each time they submit a survey, be immediately randomized to receive (or not receive) a just-in-time intervention tailored to their level of current suicidal thoughts * Answer brief follow-up questions on their smartphone within a couple hours of each randomization * Provide feedback on their experience with the just-in-time interventions Read Less

This study uses a noninvasive technique called transcranial magnetic stimulation (TMS) to study satiety in healthy individuals. TMS is a noninvasive way of stimulating the brain, using a magnetic field to change activity in the brain. The magnetic field is produced by a coil that is held next to the scalp. In this study, the investigators will be stimulating the brain to learn more about the role of the cerebellum in satiety. Read Less

Sickle Cell Disease (SCD) impairs oxygen transport to tissue and causes endothelial injury. Thus, therapeutic interventions aim to improve both, but there is an unmet need for biomarkers to determine when intervention is necessary and evaluate the effectiveness of the chosen intervention in individual patients. This study proposes to monitor SCD and its treatment through their impact on cerebral hemodynamics, as the brain is one of the most vulnerable and consequential targets of the disease. Specifically, this study will optimize quantitative magnetic resonance imaging (MRI) and advanced optical spectroscopy techniques such as frequency-domain near-infrared and diffuse correlation spectroscopies (FDNIRS-DCS) to monitor 1) cerebral oxygen transport with measures of cerebral blood flow (CBF), cerebral oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen consumption (CMRO2) and 2) endothelial function with cerebrovascular reactivity (CVR). Additionally, this study aims to monitor baseline cerebral oxygen transport and CVR, as well as changes that occur with treatment (transfusion or genetic therapy to induce fetal hemoglobin) and assess hemoglobinopathy patients with known genotypes and phenotypes. The ultimate goal is to demonstrate the potential of this monitoring approach to select individual SCD subjects for interventions and evaluate individual responses to treatment. Success will help justify inclusion of these modalities in ongoing and future clinical trials of novel SCD therapies. Read Less

Nearly 50% of older adults complain of poor habitual sleep, and in many cases the underlying reason remains undiagnosed or unknown. Meanwhile, observational data suggest that bedroom temperature significantly influences sleep quality in community-dwelling older adults, including those without financial constraints that limit the use of heating and cooling. These individuals often struggle to maintain an optimal bedroom temperature, either due to impaired motor function and cognitive abilities, and/or a lack of awareness about how temperature affects their sleep. Therefore, for a non-trivial portion of older adults, optimizing the bedroom temperature presents an exciting and untapped opportunity to improve sleep without substantial cost, burden, and side effects. The intervention, biologically adaptive control of bedroom temperature, uses wearable health trackers (e.g., a Garmin watch) and smart thermostats to automate and personalize bedroom temperature control, tailoring it to each person's unique physiology and context. Initially, individuals will be monitored in their home to determine each person's specific temperature range that promotes sleep quality, as measured by the wearable device. After the initial monitoring, the smart thermostat will maintain bedroom temperature within the optimal range for sleep for as long as the individual uses the intervention. The primary purpose of this project is to test the feasibility of biologically adaptive control of bedroom temperature as an intervention to improve sleep in older adults and gather preliminary data to facilitate sample size calculations for a definitive trial. 20 Older adults, aged 65 and above, will be enrolled and their bedrooms bedrooms will be equipped with smart thermostats. The first aim focuses on assessing the feasibility of the intervention. This includes evaluating participant recruitment and retention, the acceptability of temperature adjustments (tracked through the number of temperature overrides by participants), and the self-reported likelihood of future use. The second aim involves analyzing the mean and variance of sleep outcomes during observation and intervention phases (separately for each group), examining the degree to which they vary with temperature variations and behavioral adaptations.
