Study assessing four-channel prosthesis controller, that compares contralateral (mirrored) EMG-force training to ipsilateral EMG-target training with both limb-absent and able-bodied subjects
This study examines the influence of acute fasting and eating on self-control in adult females with and without bulimia nervosa (BN). Specifically, the study team is investigating whether differences in behavior and brain activation in response to computer tasks after fasting and after eating a meal could help to explain the symptoms of bulimia nervosa. Data will be collected using questionnaires and a technology called magnetic resonance imaging (MRI).
This study examined whether the Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI-ED), a 12-item questionnaire, can help doctors in the emergency department accurately assess a child's asthma control. This study involved an intervention with the doctors in the emergency department of an urban pediatric hospital. The intervention was done when one of the doctors involved in the study treated a child aged 1-17 years for an asthma exacerbation. Parents answered questions on the PACCI-ED about their children's asthma. Half of the doctors were allowed to see the PACCI-ED results and half were not. The two groups of doctors were compared on their ability to correctly identify asthma control categories, whether a child's asthma was worsening or improving, whether the family was administering controller medications as often as they should, and how much burden the child's asthma was for the family.
This study is designed to document the loss of sociomoral emotions (like empathy, guilt, and embarrassment) in patients with behavioral variant frontotemporal dementia. The loss of these emotions, which function as the motivators for social behavior, will manifest in specific interpersonal behaviors. These behaviors will correlate with regional changes in regional changes in medial frontal and anterior temporal lobes. These social and emotional changes will be compared with a young-onset Alzheimer's disease comparison group.
We hypothesize that our integrated closed-loop glucose-control system can provide effective, tight, and safe blood glucose (BG) control in type 1 diabetes, thereby establishing the feasibility of closed-loop BG control.
The goal of this research study is to identify biologic and lifestyle factors that may increase a person's risk of developing certain types of cancer.
Aggressive intraoperative and postoperative management of blood glucose may substantially decrease perioperative cardiovascular and infectious complications in diabetic and non-diabetic patients undergoing vascular surgery. The purpose of this study is to compare the tight versus traditional blood glucose control in diabetics and non-diabetics undergoing vascular surgery in regard to their postoperative fatal and nonfatal cardiac outcomes, and the secondary effects such as rate of infections, overall morbidity and 30-day mortality.
Our goal is to test a dentist-hygienist team intervention to help dental patients quit smoking and determine if it can be effectively and cost-effectively implemented and sustained. Staff in half of the HMO's 14 large dental facilities will be trained to provide brief cessation advice and assistance and to encourage smokers to talk by phone with a tobacco counselor before they leave the dental office. Phone counselors will provide brief counseling, assess stage, and offer a full list of cessation services. The Active Referral intervention strategy is both practical and innovative, as it takes advantage of available resources; efficiently distributes intervention activities between dentists, hygienists, and counseling specialists; and could be delivered in individual, small, or large dental practices. This intervention is provided as part of routine care to all patients seen for annual dental and periodontal exams.Consented patients will receive a short phone survey shortly after the exam to assess smoking status, satisfaction with delivery of support services,and satisfaction with intervention. Consented patients in treatment and control facilities will be surveyed by phone at one year to re-assess smoking status and satisfaction with services.
Each year in the United States, about 700 people die from pregnancy-related causes. More than half of these deaths occur after delivery, during what is often called the "fourth trimester." Many of these deaths-up to 80%-are believed to be preventable. In the first week postpartum, the most common causes of death are heavy bleeding, high blood pressure, and infection. After the first week, heart problems such as cardiomyopathy are the leading causes of death. In addition to the risk of life-threatening complications, health issues like diabetes and high blood pressure during pregnancy can increase a person's risk of developing long-term conditions such as heart disease and type 2 diabetes. Despite the importance of postpartum care, up to 40% of individuals do not attend their postpartum check-up. Attendance is especially low among people who are younger, publicly insured, or from underserved communities. Among individuals with diabetes in pregnancy, postpartum care is critical to monitor blood sugar levels, assess for type 2 diabetes, manage complications, and ensure long-term follow-up with a primary care provider. However, many do not attend this visit or receive recommended screenings. Common reasons include feeling fine, time constraints, and a lack of understanding about the purpose of the visit. The study was conducted as a pilot randomized controlled trial at a tertiary care center among pregnant individuals with type 1, type 2, or gestational diabetes. Participants were randomly assigned to receive either usual care or to watch a 3-minute animated video during a prenatal visit. After enrolling, all participants completed a baseline survey using a secure platform (REDCap) assessing their knowledge about the postpartum period and care expectations. The video was available in English and Spanish and covered key information about what to expect after delivery, warning signs for complications, and why postpartum care is important. Immediately after viewing the video, participants in the intervention group repeated the knowledge-based questions to assess changes in their understanding. Investigators reviewed the electronic medical records to assess postpartum visit scheduling and attendance. This study is designed to determine whether a brief, accessible educational video can improve postpartum care engagement among individuals with diabetes in pregnancy. If effective, this type of video intervention could be implemented more widely to improve maternal health outcomes, particularly in high-risk populations.
The purpose of this research is to prove that data generated by your real-time personal continuous glucose monitors CGMs brought in the hospital at the time of hospitalization can be monitored and safely used to guide insulin therapy aiming to improve glycemic control and to diminish the hypoglycemia and hyperglycemia episodes without negatively affecting patients' satisfaction, providers and your nurses satisfaction with how glucose is monitored and treated in the hospital.
Low back pain (LBP) is a condition that affects a majority of the US population and is responsible for a significant proportion of health care costs and utilization. Lumbar spine muscle is compromised in LBP, and do, and do not, respond to exercise based physical therapy program depending on measurements representing activation capacity of lumbar muscle. Here, we will characterize the neurological and muscle specific features that may contribute to limited activation in an attempt to identify sources of resistance to recovery in patients with chronic disc injury and identify precision rehabilitation approaches for this complex population of individuals.
The purpose of this study it to evaluate several cellular, acellular, and matrix-like products (CAMPs) and standard of care versus matched standard of care controls in the management of nonhealing pressure ulcers.
Developing efficient cognitive intervention for cognitively health older adults is a major public health goal, due to its potential for reducing age-related cognitive decline and Alzheimer's disease/dementia risk. Executive Control is a relevant cognitive target since it declines with aging and is critical for multi-tasking in daily life. The proposed research investigates whether playing a web-based cognitive complex game (the Breakfast Game) impacts cognitive performance in cognitively healthy older adults. To be enrolled in the study, participants will be asked to undergo a cognitive sassessment, health questionnires, and a blood exam. The intervention consist in one educational session on healthy aging, and 10 one-hour cognitive training sessions 2-3 times a week over one month. Participants will be asked to repeat the cognitive assessment within 1-2 weeks after the intervention, and after three months.
The overall aim of this study is to investigate the effects of exercise on the amount of glucose that is made by the liver in people with and without Type 2 diabetes (T2D) and hepatic steatosis (fatty liver).
Abstract Cognitive symptoms of Parkinson's disease (PD) include deficits in attention, working memory, and reasoning. These deficits affect up to 80% of PD patients and lead to mild cognitive impairment (PD-MCI) and dementia in PD (PDD). There is a critical need to better understand cognitive impairment in PD to develop new targeted treatments. The long-term goal is to define the mechanisms of PD-related cognitive impairment. PD involves diverse processes such as dopamine and acetylcholine dysfunction, synuclein aggregation, and genetic factors. During the past funding period, the investigators linked PD-related cognitive impairment to dysfunction in frontal midline delta (1-4 Hz) and theta (5-7 Hz) rhythms, which the work has established as a marker of cognitive control. However, it is unknown why PD patients have deficits in these low-frequency brain rhythms. The preliminary magnetic resonance imaging (MEG) and magnetoencephalography (MRI) implicate the anterior midcingulate cortex (aMCC) as a potential source of frontal midline delta/theta rhythms. In the next funding period, the objective is to determine the mechanisms and predictive power of delta/theta rhythms in PD, which will help to better understand the pathophysiology of PD-related cognitive impairment. Collaboration between the University of New Mexico (UNM) and University of Iowa (UI) that will bring together MEG, MRI, longitudinal EEG, and adaptive subthalamic (STN) deep-brain stimulation (DBS). The investigators will test the overall hypothesis that frontal midline delta/theta dysfunction contributes to cognitive impairments in PD. In Aim 1, the investigators will determine the structural basis for delta/theta rhythm deficits in PD. In Aim 2, the investigators will determine the predictive power of delta/theta rhythm deficits in PD. In Aim 3, the investigators will determine how tuned low-frequency STN DBS impacts cortical activity and cognition. The results will have relevance for basic-science knowledge of the fundamental pathophysiology of cognitive impairment in PD and related dementias. Because this proposal will study patients with PDD, the findings are directly relevant to Alzheimer's-related dementias (ADRD).
The investigators recently demonstrated that blockade of Glucagon-Like Peptide-1's (GLP-1) receptor (GLP1R) results in changes in islet function without changes in circulating GLP-1. These effects are more pronounced in people with early type 2 diabetes (T2DM) in keeping with increased expression of PC-1/3 and GLP-1 that is observed in diabetic islets. However, its regulation is at present unknown. There is evidence that α-cell proglucagon processing is subject to paracrine regulation by the β-cell3. It is unclear if the effects of GLP1R agonism on islet GLP-1 differ in Type 1 diabetes (T1DM) compared to T2DM. This experiment will examine the effect of glycemic control ± a GLP1R agonist on islet GLP-1 in people with (T2DM) and without (T1DM) β-cells.
The primary objective of this new line of research is to test whether augmenting sensory information from the legs, using Walkasins sensory neuroprosthesis, can enhance performance of a complex walking task in older adults with foot sensory impairment. The overarching hypothesis is that Walkasins will enhance the automaticity and reduce cognitive demand of walking in older adults with foot sensory impairments, as measured by reduced prefrontal activity, decreased dual-task costs, and lower gait variability.
This is a double-blind randomized controlled trial of standard of care therapy, either oral ketorolac (experimental group) or oral oxycodone (control group) to demonstrate efficacy in reducing the percentage of narcotic doses taken and documenting the number of patients with no exposure to any narcotics (take zero oxycodone) after undergoing primary knee ACL reconstruction outpatient surgery.
This research study will evaluate human performance and postural balance changes during the course of care with flexion distraction manipulation in multiple chiropractic practices.
PAUSE 2 study is a prospective, open-label, blinded-endpoint non-inferiority RCT of PAUSE vs. ASRA management in DOAC treated high risk patients with AF/VTE who need elective high bleed risk surgery/procedure and/or any procedure involving neuraxial anesthesia. The purpose of the PAUSE 2 study is to show that PAUSE management will be as safe (i.e., non-inferior) as ASRA management, with 95% of patients having low/undetectable pre-operative DOAC levels \<30 ng/mL in each group., at the time of surgery/neuraxial.
The goal of this clinical study is to evaluate safety of Xenon gas inhalation in healthy volunteers. This first phase safety clinical study is part of evaluation of the xenon gas inhalation as a therapy for neurodegenerative diseases, such as Alzheimer's disease. The investigators will administer xenon gas in low concentration to people via anesthetic machine, observe participants for sedation and any unexpected side effects, collect blood at each visit and measure the vital signs. There are four treatment groups in the study, which correspond with the duration of xenon gas treatment. Individual participation will last approximately 14 days over five visits: screening visit accompanied by the electrocardiogram, blood, and urine test; treatment visit for xenon gas inhalation treatment; and three follow up visits.
Using a randomized control design, this study seeks to develop and evaluate a nutrition intervention to increase Montessori teachers' nutrition knowledge, nutrition self-efficacy, nutrition teaching self-efficacy and cultural food competence to improve teachers' eating behaviors, nutrition teaching practices, classroom food practices, and teacher-parent communication. This study will examine the feasibility and efficacy of a nutrition intervention for teachers which will include a nutrition education program via an online platform and hands-on Montessori-based curriculum to teach nutrition in the classroom. Teachers from multiple schools will be recruited using the public national Montessori listserv. This study will enhance teachers' nutrition knowledge which may increase their nutrition teaching practices and improve their personal nutrition habits. Improving teachers' personal and classroom nutrition practices may improve teachers' personal health outcomes and may positively impact their students through modeling of healthy behaviors and improving the classroom food environment.
The goal of this research project is to investigate how brain lesions affect our ability to generate goal-directed behaviors - a cognitive function commonly referred to as cognitive control. To support goal-directed behaviors, the human brain must adaptively direct thoughts and actions depending on the current goals and contexts. Our principal hypothesis is that this cognitive capacity depends on a brain network architecture that can flexibly transmit, select, and inhibit information along neural pathways. Therefore, lesions and damages to critical brain network components will negatively affect behavior. To faithfully assess the structure and function of human brain networks and its disruption from brain lesions, investigators will recruit healthy adult human subjects and patients with brain lesions to participate in a multi-session study that includes cognitive behavioral tests, structural magnetic resonance imaging (MRI) using a 3 Tesla (3T) scanner, and electroencephalography (EEG) studies. During all testing sessions, subjects will perform cognitive tasks that assess their ability to select, maintain, and inhibit sensory information and generate motor responses. Their eye movements may be passively recorded during testings. 3T MRI allows for fast and high-resolution imaging of brain structures, enabling us to identify lesion loci. Investigators will use EEG to measure the electrophysiology of brain activities. All behavioral, EEG, and MRI data collected will be sent to the National Institute of Mental Health Data Archive (NDA) at the National Institute of Mental Health (NIMH).
The objective of this study is to examine the effect of transcranial magnetic stimulation (TMS) on the prefrontal cortex and posterior parietal cortex.
Almost 40% of veterans have diabetes, the proposed research may improve clinical care among veterans with diabetes. In this application we are going to examine whether utilizing Smart Insulin pens (SIPs) with CGMs and telemedicine is a better tool for managing diabetes compared to traditional insulin pens, CGMs and telemedicine, leading to improved blood sugar control and better clinical outcomes.
The overall goal of the randomized control trial (RCT) will be to evaluate the efficacy of modifications to a web-based tool for patient decision-making regarding return of genomic results that will more closely focus on rare cancers. Participants will be given access to a web-based decision aid (or a standard control) that guides participants in making decisions about what type of genomic results they would like to receive from testing performed in the PE-CGS study (NCT06340646).
This study aims to compare a multidisciplinary clinical hypertension and social needs intervention to enhanced standard of care for hypertension management in primary care clinics with regards to hypertension control outcomes.
