The purpose of the study is to develop and test the feasibility of a nonmedical digital health intervention, the Spanish-language Caregiver-Enabled Care Program (CECP), with Spanish-speaking caregivers of persons with dementia (PWD). CECP is a nonmedical digital population health intervention that provides personalized education, proactive 1:1 human coaching, and remote monitoring, all delivered via a dedicated tablet shipped to the caregiver's home at no cost to the caregiver or PWD. For this study, the investigators are recruiting 135 patient/caregiver dyads. Read Less

There is a growing sector of modern tobacco-free oral nicotine pouches that are federally regulated as non-medicinal nicotine/tobacco products. While nicotine pouches employ marketing approaches that may attract current tobacco users, such as marketing themes connoting minimal harm, information on the long-term health effects of nicotine pouches is lacking. nicotine pouches may appeal to younger adults because they are available in similar product characteristics (e.g., nicotine concentration, protonated nicotine) that many younger people prefer to use in e-cigarettes. In addition, nicotine pouches may be of particular interest to younger adult e-cigarette users because these products can be used discreetly where vaping is not allowed, which may translate into an increased likelihood of becoming dual users of e-cigarettes and nicotine pouches. Indeed, approximately 15% young adults who used e-cigarettes in the past 30 days were past 30-day nicotine pouch users. Manufacturers of modern nicotine pouches use acid additives to lower pH, which changes nicotine from a free-base to a protonated nicotine, resulting in improved appeal and sensory experience and higher abuse liability. Thus, nicotine concentration and pH in modern nicotine pouches should be focal targets for regulatory policies. Evidence is also lacking on mechanisms mediating differences in product appeal and abuse liability of nicotine pouches across products varying in nicotine concentration and pH level. The scientific objective of this research is to assess the effect of variation in nicotine concentration in nicotine pouches and its interaction effect with pH level on the proximal outcomes of relevance to the U.S. Food and Drug Administration regulation: sensory attributes and product appeal among younger adults who use nicotine pouches in the past 30 days (current dual users of nicotine pouches and e-cigarettes and/or combustible cigarettes will be eligible) and are unmotivated to quit nicotine use. This innovative project proposes to conduct a double-blind within-subject randomized study in which participants (N = 72) will administer nicotine pouches varied by nicotine concentration (e.g., 3 vs 6 mg) and pH (e.g., 8.5 or greater vs. less than 8.5) to achieve the project aim: to evaluate the effects of nicotine concentration and pH on subjective product appeal and sensory attributes of nicotine pouches. The findings of this proposed research will provide the U.S. Food and Drug Administration with new evidence necessary to inform regulatory restrictions on product characteristics and constituents of nicotine pouches, which may put young adults at risk of using a novel class of oral nicotine products.

The purpose of this study is to investigate areas of the brain responsible for avoidance learning in adults with eating disorders using brain imaging techniques, computer tasks, and self-report questionnaires and interviews. The investigators will study changes in brain activity using a procedure called functional magnetic resonance imaging (fMRI). This study will include 78 women with an eating disorder (26 with anorexia nervosa \[AN\], 26 with bulimia nervosa \[BN\]) and 26 healthy controls (HC) aged 18-39. Aim 1: Evaluate behavioral differences in active and passive avoidance learning in eating disorders and associations with symptoms. Aim 2: Evaluate whether corticostriatal and limbic-prefrontal fMRI BOLD response associated with avoidance learning differs in eating disorders relative to healthy controls and relates to symptoms. Aim 3: Evaluate whether functional connectivity of avoidance learning neural circuity differs in eating disorders relative to healthy controls. Read Less

This project will study changes that occur during a short period of intensive daily slow-paced breathing and breath hold practice (i.e., "breathwork"). On the first and last days of the week-long practice, investigators will conduct high-density EEG recordings during breathwork to evaluate spectral power, coherence, and causality dynamics of the brain when it is naïve to breathwork and after adaptation to a breathwork practice. Breath, blood, urine, saliva, stool samples, biometric data, and sleep EEG will be collected before the start of daily breathwork practice and again after 1 week of breathwork practice to examine the effect of breathwork on full body biochemistry, molecular biology, and sleep. Investigators will also use questionnaires to assess the impact of breathwork on stress and sleep quality. Read Less

Long-chain cyclopropane fatty acids (CpFAs) are microbially-derived lipids (fats), some of which can be found in select foods and appear to be produced naturally in the gut from dietary fatty acid precursors. Some of these lipids appear to have signaling properties in the body's tissues, i.e., to help regulate cardiometabolic health. Thus, increasing the bioavailability of CpFAs in humans may have utility to improve management of blood sugar and blood lipids, or to mitigate or prevent non-alcoholic fatty liver disease (NAFLD). This study is a proof-of-principle experiment in 10 subjects, to feed dietary fats thought to enhance upper gut CpFA production. The latter will be monitored through post-meal blood and urine CpFA concentration measurements, as well as concentration in the stool. Read Less

The goal of this study is to understand whether providing information to women with a strong desire to avoid future pregnancy about how tubal sterilization compares to long-acting reversible contraceptives improves perceived access to available contraceptives. Participants will: * Complete a baseline survey * Receive access to web-based educational resources * Complete a brief follow up survey immediately after exploring these web-based resources * Complete a follow-up survey 3 months after enrolling The investigators will compare outcomes among participants provided with access to a new website (intervention) summarizing recent patient-centered outcomes research (PCOR) comparing interval laparoscopic tubal sterilization and long-acting reversible contraception (LARC) to control participants provided with access to the existing Planned Parenthood website on tubal sterilization.

The goal of this combination Type 1 hybrid and observational study is to evaluate the impact of a peer delivered intervention of acceptance and comittment therapy(ACT) + exercise + social support to address the substance (ab)use, violence, and AIDS/HIV (SAVA) to improve medication adherence for women living with HIV (WLWH). This intervention will be implemented by community based organizations that focus on WLWH across four counties. The main question it aims to answer are: * Will peer provision of ACT, exercise, and social support improve medication adherence for WLWH? * Will community based organizations be able to sustain the intervention after research is completed, and what changes will need to be made to sustain th eintervention.

Bleeding from intra-abdominal injuries is a leading cause of traumatic deaths in children. Abdominal CT is the reference standard test for diagnosing intra-abdominal injuries. Compelling reasons exist, however, to both aggressively evaluate injured children for intra-abdominal injuries with CT and to limit abdominal CT evaluation to solely those at non-negligible risk. The focused assessment sonography for trauma (FAST) examination can help focus patient evaluation in just this manner by potentially safely decreasing abdominal CT use in low risk children. This research study is a multicenter, randomized, controlled trial to determine whether use of the FAST examination, a bedside abdominal ultrasound, impacts care in 3,194 hemodynamically stable children with blunt abdominal trauma. The overall objectives of this proposal are 1) to determine the efficacy of using the FAST examination during the initial evaluation of children with blunt abdominal trauma, and 2) to identify factors associated with abdominal CT use in children considered very low risk for IAI after a negative FAST examination. The long-term objective of the research is to determine appropriate evaluation strategies to optimize the care of injured children, leading to improved quality of care and a reduction in morbidity and mortality.
