Fibromyalgia (FM) is a chronic pain condition that disproportionately impacts Veterans. Individuals diagnosed with FM patients experience lower self-esteem and positive affect, as well as greater levels of depression, anxiety, negative affect, and pain catastrophizing. Among those experiencing FM, clinical and experimental pain are associated with specific dispositional trait profiles, which are indexed by levels of negative affect and positive affect. Neuroinflammation and inflammation also play a role in FM- related affect and pain. Recent studies that have highlighted neuroinflammation and inflammation as physiological mechanisms associated with changes in dysregulated affect and chronic pain. Veterans with FM can ameliorate their dispositional traits-i.e., increasing positive affect and reducing negative affect-by participating in exercise. However, a gap exists regarding how to optimally engage Veterans with FM in an exercise program. Thus, to fully take advantage of all potential therapeutic benefits of exercise for FM, there is a critical need to identify those factors underlying exercise engagement for FM pain management. The purpose for this study is to 1) determine associations of dispositional trait styles, neuroinflammation, and inflammation with pain outcomes in Veterans with FM; and 2) develop and design a Veteran-informed exercise program.
The goal of this clinical trial is to test if a mindfulness-enhanced positive affect induction (MPAI) works well to reduce pain intensity and pain unpleasantness from a cold water pain test in undergraduate college students who do not endorse ongoing medical or mental health diagnoses. The main questions it aims to answer are: * Is the MPAI a feasible and acceptable psychological technique for managing brief pain? * Does the MPAI work well to reduce pain intensity and unpleasantness from experimentally induced brief pain, compared to those using a breathing meditation or those instructed to respond naturally. * Does using the MPAI work well to improve confidence in self-managing brief pain? Participants will be asked to complete questionnaires about their sleep, pain beliefs, and emotions after consenting to participate and at the end of the study session. They will then be randomized to either: * Use the MPAI for managing pain induced by a cold water test (placing their hand in a container of cold water kept at approximately 5 degrees Celsius). * Use a breathing meditation for managing pain induced by a cold water test (placing their hand in a container of cold water kept at approximately 5 degrees Celsius). * Respond naturally to pain induced by a cold water test (placing their hand in a container of cold water kept at approximately 5 degrees Celsius). Researchers will compare the MPAI group to the breathing meditation and natural response groups to see if the MPAI group reports less pain from the cold water test and
This randomized controlled trial will assess the effects of External Cues focused messaging (i.e., government recommendations of MyPlate) compared to Internal Cues focused messaging (i.e., intuitive eating). The investigators will collect data on within-person changes in psychological (e.g. affect) and physiological (e.g. heart rate variability) outcomes in female college students. Participants will be randomly assigned to one of two study conditions. In condition one, participants will view a five-minute video focusing on traditional nutrition education principles. In condition two, participants will view a five-minute video focusing on intuitive eating principles.
This study will examine how the use of antidepressant, physical therapy, and combination of both affects pain, function, and depression outcomes in chronic low back pain patients.
The project's objective is to explore the impact of Mindfulness-Based-Stress-Reduction (MBSR) on pain regulation, social stress, basic affective and attention functions, and on the brain, immune, and endocrine mechanisms that subserve these processes. Specifically, the investigators hypothesize that participants undergoing MBSR training will show decreased emotional distress on self-report measures, increased sustained attention on a behavioral task, decreased stress levels on a social stress test, decreased general psychosocial stress as indexed by diurnal salivary cortisol profile, changes in inflammatory response, modulation of cellular aging, and different neural patterns in response to thermal pain and aversive visual stimuli as indexed by functional Magnetic Resonance Imaging (fMRI). To test these hypotheses, the study will recruit 50 participants through the UW-Madison Integrative Medicine Program. All participants will be randomly assigned either to an 8-week MBSR program or to an 8-week training program in health-enhancement. At the conclusion of the study, participants will be invited to participate to the second class should they be interested. Participants will complete self-report questionnaires, behavioral tasks, fMRI scanning, cortisol sampling, and blood sampling before training begins, after the first program ends, and again four months after the first program ends and prior to the second program. If hypotheses are supported, the study may benefit participants by reducing their psychological distress, increasing their well-being, and helping them better manage pain and aversive stimuli. There are no other direct benefits to participants. Potential risks associated with fMRI include ferromagnetic collision, neurostimulation effects, and psychological discomfort. Potential risks to subjects include slight potential discomfort in providing saliva samples, discomfort of painful thermal stimulation, stress associated with the Trier Social Stress Test, some psychological discomfort from viewing disturbing photographs as part of the compassion fMRI study, and breach of confidentiality. Consent for the present study will entail both written and verbal descriptions of the protocol. Subjects will be informed that their participation is completely voluntary, and that they can withdraw at any time.
The purpose of this study is to examine the role of emotion and mood in the context of HIV.
The investigators are studying whether a brief three-session mind-body workshop helps people with fibromyalgia. The investigators hypothesize that this workshop will significantly improve pain and other symptoms, compared to usual care.
The purpose of this research is to evaluate the effectiveness of three training programs designed to teach persons with acquired brain injury (ABI) to recognize emotions. It is hypothesized that the training programs will enhance several aspects of emotion recognition in persons with ABI. Furthermore, it is expected that these effects will be maintained over time, and will positively influence participants' social behavior and integration.
This double-blind randomized crossover study aims to examine the effects of left primary motor cortex (M1) tDCS on evoked thermal pain perception, pain-related decision making, and placebo effects by manipulated pain and monetary offers accepted by others. The investigators plan to collect data for up to 50 participants who undergo four separate sessions: an initial pain calibration session and three experimental sessions with either anodal, cathodal, or sham tDCS. Each session includes pain testing before and after a single tDCS protocol (either anodal, cathodal, or sham), a pain-monetary decision-making task, and social placebo pain tests. All tasks following tDCS will take place inside the MR scanner. The investigators hypothesize that anodal M1 tDCS will decrease pain ratings, and that cathodal tDCS will increase them, both relative to the sham condition. The investigators will also examine the effects of M1 tDCS on social decision-making to examine whether it affects participants' valuation of pain and their altruistic behavior, as well as how these same factors impact pain sensation in the placebo task. The investigators hypothesize that participants will behave hyperaltruistically during the decision-making task, and that the same factors that influence choice will also impact pain perception in the same context.
The goal of this clinical trial is to learn whether non-invasive brain stimulation, called transcranial temporal interference stimulation (tTIS), can reduce negative affect, and how expectations shaped by care providers influence these effects. The main questions this study aims to answer are: (1)Does active tTIS reduce negative affect more effectively than sham (inactive) tTIS? (2)Do positive treatment expectations enhance the effects compared to negative expectations? Participants will: (1) Receive either active or sham tTIS. (2) Be provided with positive or negative messaging regarding treatment effectiveness. (3) Interact with care providers and complete assessments measuring negative affect and physiological responses.
The purpose of this study is to measure the effect of multiple doses of AZD2389 on the pharmacokinetics (PK) of midazolam, caffeine, and bupropion in healthy participants.
The long-term study goal is to experimentally evaluate the components (and likely active ingredients) of early language interventions for young children with Down syndrome (DS). The overall objective is to determine how single-word and telegraphic simplification affects real-time language processing and word learning in young children with DS (relative to full, grammatical utterances). The proposed project will investigate three specific aims: 1) Determine how single-word and telegraphic simplification affects language processing. 2) Determine how single-word and telegraphic simplification affects word learning. 3) Evaluate child characteristics that may moderate the effects of linguistic simplification on language processing and word learning. Aim 1 will test the hypothesis that children with DS will process grammatical utterances faster and more accurately than telegraphic or single-word utterances. Aim 2 will test the hypothesis that overall, children will demonstrate better word learning in the grammatical compared to the single-word and telegraphic conditions. Aim 3 will test the hypothesis that receptive language and nonverbal cognitive abilities will be significant moderators, such that children with stronger linguistic and cognitive skills will show the greatest benefit from grammatical input but children with lower linguistic and cognitive scores will perform similarly across conditions.
The goal of this mixed-methods study is to assess the impact of a Community Health Worker (CHW)-led social risk screening and referral in improving management of uncontrolled diabetes (DM) and hypertension (HTN) among patients receiving care in community health centers (CHCs or health centers). The intervention is focused on adult health center patients with uncontrolled DM and/or HTN. Study findings will provide important evidence to guide CHCs in implementing programs to address social risks in their patient populations. Findings will illuminate whether and how CHW-led interventions to address social needs yield the hypothesized outcomes. The aims of the study are: * AIM 1: Measure how effective the CHW-led social risk program is at reducing blood sugar levels (A1C) in CHC patients with uncontrolled DM and lowering blood pressure in CHC patients with uncontrolled HTN. * AIM 2: Identify effective strategies for increasing and expanding CHW-led social risk programs.
The goal of this clinical trial is to find out whether learning about well-being impacts the thoughts and feelings of romantic couples. The main question it aims to answer is: * Does gaining knowledge about well-being positively impact individuals and their romantic relationships? Participants will complete online surveys about their thoughts and feelings.
This study will assess the effect of food (high fat) on oral ABBV-101 and how ABBV-101 moves through the body in healthy adult participants
The purpose of this research study is to investigate how personality traits and neuroendocrine systems relate to decision-making patterns in individuals 18-45 years old. The main question it aims to answer is how neuroendocrine activity impacts decision-making. Participants will complete online behavioral tasks, a stress induction procedure, self-report surveys, and a cognitive assessment. During the session, psychophysiological measures will be collected, including electrocardiogram (ECG) and cardiac impedance (ICG) to monitor heart rate and blood flow, as well as electrodermal activity (EDA), blood drop samples, and saliva collection to assess nervous system activity.
The investigators are assessing how seasonal changes affect kidney function biomarkers in post-menopausal women, an understudied group. While heat stress can reduce kidney function, previous research has not accounted for physical activity, diet, hydration, or sun exposure.
The objective of this proposal is to determine whether heightened negative affective responsivity (NA-R) to daily stressors is related to blunted nitric oxide (NO)-mediated endothelium-dependent dilation (EDD) in working age adults and the extent to which this association is impacted by major depressive disorder (MDD).
The goal of this study is to examine attentional biases for facial displays of emotion as a mechanism of risk in infants of mothers with postpartum major depression, and the potential role of infant arousal in the development of these attentional biases.
The purpose of the study is learn more about ways to help people with non-medical issues that can affect participant health. The study team will examine if Community Health Workers, members of a community who provide basic health and medical care within communities, are more helpful to people with non-medical issues than simple reading materials on how participants can do it.
There has been much interest in the potential role of social media (SM) use in driving a current mental health crisis among teens, with a dire need for evidence that goes beyond self-report. One important avenue is to understand the role of the brain in driving the effects of SM use on emotional health and vice versa. However, there is almost no research addressing these questions, largely due to a lack of tasks that can probe the neural correlates of modern SM use. The goal of this clinical trial is to develop and validate a new developmentally-appropriate and ecologically-valid functional magnetic resonance imaging (fMRI) and eyetracking task, the TeenBrainOnline (TBO) Task, that is more realistic and similar to modern SM platforms. Participants will be 50 teens (ages 13-17) with depressive symptoms who will complete the final version of TBO task during fMRI with eye-tracking, an older Chatroom Interact (CHAT-I) Task, daily surveys of SM use, and measures of depressive symptoms. Our goal is to show that the task works by: * Demonstrating that it activates expected regions of the brain and visual attention biases toward feedback cues. * Showing that brain and eyetracking (visual attention) activity on the task explain variability in depressive symptoms at baseline and three months later, and work better than similar indices from an older task. * Showing that brain and eyetracking (visual attention) activity on the task are associated with real-world measures of social media use collected during daily surveys. Specifically, The investigators expect that teens whose brain and eyetracking activity suggests they are more sensitive to feedback on SM will report a social evaluation orientation toward social media use in daily life, such as engaging a lot in social comparison, worrying about missing out, and caring about getting a lot of likes and comments. Participants will be asked to: * complete a 10-15 minute screening call to determine eligibility for the study * complete one 90 minute virtual study visit to complete questionnaires and prepare for the MRI visit (visit 1) * submit 24 photos to our study specific social media site * complete an (in person) MRI scan visit (\~4 hours), which consists of 2 tasks where they will interact with peers (visit 2) * complete \~5 minute smartphone surveys 3 times a day for 16 days, asking about their daily experiences online and emotional reactions. * complete 2 online questionnaires asynchronously 3 months after their scan date
Participants will be asked to participate in this research study of a device that creates transcranial direct current stimulation (tDCS). The researchers hope to learn if 30 minute sessions of transcranial direct current stimulation (tDCS) improve such a mood or feelings in people with Alzheimer's Disease. This study involves the use of an investigational device called a tDC stimulator. "Investigational" means that the device has not yet been approved by the U.S. Food \& Drug Administration (FDA) for treating Alzheimer's Disease. This study will help find out what effects, good and/or bad, this has. The safety of this device in humans has been tested in prior research studies; however, some side effects may not yet be known.
The goal of this clinical trial is to investigate how iron status and heavy bleeding during the menopausal transition affect women's cognitive function and quality of life. The main questions it aims to answer are: * What is the association between iron status, cognitive function, mood, quality of family relationships, and quality of life in perimenopausal women? * How does iron repletion, via supplementation, affect cognitive function, mood, quality of family relationships, and quality of life in perimenopausal women? The investigators will compare the effect of iron supplements to a placebo (gelatin capsule) to see if iron supplements could improve iron status, cognitive function, mood, quality of family relationships, and quality of life of iron-deficient and/or anemic women undergoing the menopausal transition. Each participant will: * Make 2 visits (about 2 hours each - baseline and endline) to the Clinical Research Center at Purdue * Make a very brief visit at midpoint (about 10 minutes) for a checkup * Take a daily study supplement or placebo for 4 months
This is an observational study in which data from women with sleep disturbances and vasomotor symptoms, also known as hot flashes, associated with menopause (SDM) are collected and studied. Menopause is part of a natural aging process and happens when women's menstrual cycles, also called periods, stop. Sleep disturbances, such as frequent waking up at night, are a common symptom (clinical sign) and a major worry associated with menopause that affects women's quality of life. The participants will continue to take their regular treatment for their SDM as agreed with their doctors. These are called "standard of care" treatments. Because both patients and doctors don't know much about SDM, women are often treated with sleep medicines that can lead to addiction and cause side effects. This study will help us to learn more about how much menopause-related sleep problems affect a woman's overall health and well-being. We also want to find out how women are currently being treated or treat themselves for these sleep problems, so we can figure out if there's a need for new treatments that focus specifically on menopause-related sleep issues To do this, researchers will collect information on: * the number of times a woman wakes up during the night and the total time she is awake after she first falls asleep * the time when a woman goes to bed and when she wakes up in the morning * how long it takes for a woman to fall asleep after going to bed * changes in sleep problem questionnaire scores to assess how these problems affect a woman's quality of life The data will come from combining all the electronic health record databases, patient related questionnaires, and data from smartwatches that the women will wear on their wrists. The data will be collected between November 2024 to May 2025. In this study, researchers will combine all the electronic data during a 28-day follow-up period. No visits or tests are required as part of this study.
Segmental facilitation, originally proposed by Korr in the 1950s, suggests that certain spinal segments can become hyperexcitable, leading to chronic pain development. In a facilitated segment, neurons governing sensory, motor, and autonomic functions are in a state of heightened sensitivity, making them responsive to normally weak stimuli. Clinical signs include non-fatigable muscle weakness, brisk reflexes, muscle hypertonicity, tenderness upon palpation, and trophic changes like an orange-peel appearance in the affected segment's innervated areas. It's hypothesized that increased synaptic excitability in facilitated segments could cause vasoconstriction and reduced blood flow, contributing to trophic changes and muscle hypertonicity. Manual therapies like dry needling have been shown to alleviate muscle inhibition in the extremities. Previous studies have demonstrated that mobilization of the C5-6 joint can reduce non-fatigable weakness in shoulder external rotators primarily innervated by these segments. However, the neurophysiological effects of dry needling (DN) on muscle inhibition due to a facilitated segment remain unclear. While DN has been observed to increase local tissue blood flow, its potential to mitigate the clinical signs of segmental facilitation is uncertain. While DN has been observed to increase local tissue blood flow, its potential to mitigate the clinical signs of segmental facilitation is uncertain. Therefore, this project aims to investigate whether DN applied at a facilitated segment could normalize blood flow to its associated muscles. Specifically, this study will explore whether DN at the C5-6 level improves blood flow in the infraspinatus muscle, enhances shoulder range of motion, and influences muscle strength over time. The secondary purpose is to determine whether C5-6 DN will reduce the number of tender points in the muscles supplied by C5-6.
The purpose of the study is to learn about safety, how the body processes marstacimab and how it works in patients with severe hemophilia A. A rare bleeding disorder where the blood doesn't clot normally. This causes a person to bleed a lot, even from a small cut. These patients can be with or without inhibitors who are on emicizumab medicine for routine prophylaxis for at least 6 months, and desire to switch to marstacimab medicine. Inhibitors are antibodies that the immune system develops because it sees the infused clotting factor as a foreign substance that needs to be destroyed. Antibodies are proteins that eat up the activated factor before it has time to stop the bleeding. Prophylaxis are preventive medicines. This study is seeking for participants: * with severe Hemophilia A who are on emicizumab treatment for at least 6 months. * must be 12 to less than 75 years old * must have a body weight of at least 35 kilograms. The results from this study will serve as a guide to doctors and their hemophilia A patients who will change their medicines in the real-world clinical setting. Patients who can take part in the study will receive marstacimab medicine as weekly injections under the skin of 150 milligrams for 4 months. Study treatment with marstacimab will be initiated no earlier than 14 days after last dose of emicizumab. The study can last up to 6 months. The sponsor will provide marstacimab. Patients will continue their usual treatment with the infused clotting factor for their bleeds when taking part in the study.

The specific aims are as follows: * Aim 1: To examine the effects of acute aerobic exercise at 60-70% heart rate reserve (HRRmax) for 30 minutes bout on changes in the abundance of SCFA-producing bacteria and their functional downstream metabolic activity. * Aim 2: To examine the effects of acute aerobic exercise at 60-70% HRRmax 30-minute bout on changes in GM-released SCFA concentrations in stool and plasmatic metabolome.
The primary purpose of this study is to assess the effect of mitapivat on the single oral dose pharmacokinetics (PK) of midazolam in healthy participants.
In this study, researchers will learn more about the safety of BIIB141, also known as omaveloxolone or SKYCLARYS. This is a drug available for doctors to prescribe for people with Friedrich's Ataxia, also known as FA. This is known as an "observational" study, which collects health information about study participants without changing their medical care. Participants for this study will have taken BIIB141 at any time during pregnancy and/or while breastfeeding or pumping up through the first year after delivery. Participants can join this study on their own or they may be enrolled by their regular doctors. This study is also known as the "SKYCLARYS (Omaveloxolone) Pregnancy and Lactation Surveillance Program." The main objective of this study is to learn more about how BIIB141 may affect pregnancy, as well as any effects on the health of the mother and of the baby during its first year of life. The main question researchers want to answer in this study is: · Does taking BIIB141 during pregnancy or breastfeeding lead to any major birth defects? Researchers will also learn more about: * Does taking BIIB141 during pregnancy or breastfeeding lead to any minor birth defects? * Does taking BIIB141 during pregnancy or breastfeeding affect the following: * Gestational diabetes, a disease that can happen during pregnancy that affects how your body uses sugar * Pre-eclampsia, a pregnancy-related high blood pressure disease * Unborn baby being small for its expected age (usually in weeks) * Loss of an unborn baby * Live birth * Premature birth * Loss of a newborn * Growth or developmental delays in the baby * Serious illness in the baby resulting in hospitalization * Serious infections in the baby, or ones in babies with a weakened immune system This study will be done as follows: * Participants will join the study after signing an informed consent form, also known as an ICF. * During the study, health information from the participants' regular visits to their doctor will be collected based on whether participant joined the study while pregnant or after the baby is born. * Each participant will be in the study for up to 1 year after the birth of their child, unless they decide to leave early. Overall, this study is expected to last at least 10 years.
The purpose of this research study is to investigate the effects of different forms of a gentle form of electrical stimulation applied to the ear, known as transcutaneous auricular vagus nerve stimulation (taVNS). The research team is interested in how the different forms affect comfort and tolerability, as well as how well it works.
