Stand Up for Your Health with a Sit-stand Desk
Medical College of Wisconsin Pre Diabetes Obesity Metabolic Syndrome Sedentary Behavior
More than 84 million - or 1 out of every 3 U.S. adults - have prediabetes, a condition that if not treated often leads to type 2 diabetes within five years.

More than 84 million - or 1 out of every 3 U.S. adults - have prediabetes, a condition that if not treated often leads to type 2 diabetes within five years. Average medical expenditures among diabetics are about 2.3 times higher than expenditures for people without diabetes. Physical inactivity and elevated body mass index (BMI) are major risk factors for the disease. Sedentary behavior is becoming increasingly prevalent with the growth of a 'work from home' culture, most recently driven by the COVID-19 pandemic. Cross-sectional epidemiologic data report significant associations between high amounts of sedentary (sitting) time and prevalent cardiovascular disease and diabetes. In our pilot study of 15 subjects with sedentary office jobs, 6 months of sit-stand desk use resulted in a 23% improvement in insulin resistance, most substantial in those who decreased daily sitting by over 90 minutes/day. Additional improvements in vascular endothelial function and triglyceride levels were seen without any change in exercise activity, step counts, or body weight. These findings not only corroborate epidemiologic findings on this topic but suggest causality and warrant a randomized control trial. The investigators hypothesize that adult subjects at-risk for diabetes will improve insulin sensitivity, metabolic and vascular (endothelial) health with a sit-stand desk intervention at work (whether in the office or at home), in the context of a randomized, controlled trial. The investigators will randomize 198 sedentary office workers with a BMI≥25 at risk for type 2 diabetes mellitus in a 1:1:1 ratio of three groups: (a) sit-stand desk intervention targeting 2 hours standing per day; (b) sit-stand desk intervention targeting 3 hours standing per day; or (c) control arm over 6 months. The block randomization design will allow for important dose-response analyses. The investigators will objectively quantify standing time, sedentary time, sedentary bouts, daily steps, and exercise activity times using a compact and re-usable accelerometer that adheres to the subject's thigh. This will provide objective assessments of activity levels and sedentary times for 7 full days each at baseline, 3 and 6 months. The device is equipped with an inclinometer to classify posture (sitting verses standing).

TRAC-ER Intervention to Reduce Risky Alcohol Use and HIV Risk
University of Kentucky Risk Behavior Alcohol Use Disorder HIV Infections

Ecological momentary interventions (EMI), which use phones to deliver messages to reduce alcohol use and related risk behaviors during or prior to drinking events, can help to address triggers in real-time. GPS tracking can determine when individuals visit places they have previously reported drinking or triggers to drink and then EMI messages can be delivered upon arrival to prevent risky alcohol use. A mobile app has been developed that uses GPS tracking to determine when individuals visit "risky" places and then delivers a survey asking what behaviors they engaged in while at the location. The goal of the proposed study is to use this app to enhance the Tracking and Reducing Alcohol Consumption (TRAC) intervention by delivering messages that encourage participants to employ strategies discussed during TRAC sessions when arriving at risky places. When they leave these places, they will complete a survey and breathalyzer reading in order to collect event-level self-report and biological data on alcohol use and HIV risk. If their breathalyzer result indicates alcohol use, they will receive harm reduction messaging. It is expected that combining TRAC with EMI ("TRAC-ER") will increase effectiveness by reinforcing topics discussed during these sessions, providing in-the-moment messaging to address triggers, and collecting real-time alcohol use data.

Often when people with asthma get a virus caused by the common cold (rhinovirus), they also experience an increase or worsening of their asthma symptoms. The purpose of this study is to see if the study medication dupilumab helps prevent those with mild to moderate asthma from having increased asthma symptoms, after being exposed to an experimental rhinovirus inoculation. This is a study about dupilumab which is a drug approved by the U.S. Food and Drug Administration (FDA) for treatment of moderate to severe asthma. Dupilumab is a medication that blocks pathways that cause asthmatic inflammation in the lungs, leading to symptoms and worsening lung function. During this study, subjects will be given either dupilumab or placebo and will subsequently be exposed to the the "common" cold virus (rhinovirus). The virus that the investigators are using has been safely used before in many studies like this involving thousands of volunteers, and the safe use of the virus in this research study has been reviewed by the FDA. The investigators will track asthma symptoms during the study with lung function tests, questionnaires, specimen collection, biomarkers, and physical exams. For data analysis the investigators will assess the samples collected to determine changes in the treatment groups. The investigators will also asses the symptom scores and deviations from baseline measures for lung function.

Mechanism-based acne treatment for transgender patients receiving testosterone currently does not exist and is an unmet medical need. This study explores clascoterone to treat testosterone induced acne. Many treatments we use to treat acne in females cannot be used in transgender males because they interfere with hormone therapy. Androgens have been associated with the development of acne vulgaris. Recently, a topical androgen receptor inhibitor cream (clascoterone) has been FDA-approved for the treatment of acne. However, clinical trials of clascoterone have excluded participants on exogenous hormones. Clascoterone has been hypothesized to be effective in the treatment of acne in transgender male participants on masculinizing hormone therapy, but it has never been studied or reported in the literature.

Dementia is the most expensive medical condition in the US and increases in prevalence with age. More than 5 million Americans have Alzheimer's disease, the most common form of dementia. Mild cognitive impairment is a transitional stage between normal cognitive aging and Alzheimer's disease or another type of dementia, and is indicative of higher risk for dementia. In addition to the obvious health and quality-of-life ramifications of dementia, there are high direct (e.g., subsidizing residential care needs) and indirect (e.g., lost productivity of family caregivers) economic costs. Implementing interventions to prevent MCI and dementia among older adults is of critical importance to health and maintained quality-of-life for millions of Americans. Recent data analyses from the Advanced Cognitive Training in Vital Elderly study (ACTIVE) indicate that a specific cognitive intervention, speed of processing training (SPT), significantly delays the incidence of cognitive impairment across 10 years. The primary contribution of the proposed research will be the determination of whether this cognitive training technique successfully delays the onset of clinically defined MCI or dementia across three years.

The goal of this clinical trial is to test the effectiveness of a Smart Bassinet to prevent/mitigate postpartum mood disorders by augmenting maternal sleep and/or enhancing infant sleep. The investigators will conduct a 2-arm randomized controlled trial (RCT) to compare infant and maternal sleep of infants who use a smart bassinet (SB) or a standard commercially available bassinet (Halo Bassinest Swivel Sleeper 3.0) (usual/traditional care (TAU)). After confirmation of eligibility, participants (N = 342) will randomly be assigned to either the SB or TAU. The investigators hypothesize that use of the SB will be associated with better infant and maternal sleep over a 6-month period, and these mothers will report fewer depressive and anxiety symptoms across the postpartum. The main question[s] it aims to answer [is/are]: Aim 1: Determine the effect of the SB on infant sleep and maternal sleep. [primary hypothesis or outcome measure 2]? Aim 2: Determine the effect of the SB on maternal postpartum depressive symptoms and evaluate the model that the association between the SB and postpartum depressive symptoms is mediated by both infant and maternal sleep Aim 3: Compare trajectory of immune system function from late pregnancy through postpartum between PPD and non-PPD and between SB and TAU groups Exploratory Aim. Evaluate whether the elevated risk demonstrated by previously identified PPD epigenetic biomarkers at the TTC9B and HP1BP3 genes can be modified by using a SB. The investigators hypothesize that the elevated risk will be reduced in the SB condition compared to TAU. Military-affiliated pregnant women will be recruited from across the US via social media and advertising. Monthly online questionnaires will be completed by the mother. Objective sleep data will be collected monthly using an actigraph for 1-week from both mother and baby. Blood samples for assay of inflammatory markers will be collected at enrollment, 3- and 6- months postpartum.

Cardiovascular diseases are the leading cause of morbidity and mortality and contribute most to healthcare costs in the U.S. Age is the strongest cardiovascular disease risk factor, with >90% of all deaths from cardiovascular disease occurring in adults >50 years old. The age-associated increased risk of cardiovascular disease is due, in large part, to the development of arterial dysfunction, including endothelial dysfunction and stiffening of the large elastic arteries. Therefore, novel, effective interventions that improve arterial function will have a large public health impact by decreasing the risk of cardiovascular diseases. The short-chain fatty acid acetate is endogenously produced by the gut microbiome from fermentation of dietary soluble fiber. High-fiber diets reduce risk of cardiovascular diseases, but unfortunately, a low percentage of Americans meet guidelines for adequate dietary fiber intake and, despite nationwide efforts to improve this, trends in fiber intake have not improved over the last 20+ years. Thus, directly supplementing acetate may be a more practical and feasible intervention for effectively improving arterial function in older adults and reducing the risk of cardiovascular diseases. The investigators will conduct a study to determine the efficacy of 12 weeks of oral supplementation with acetate for improving arterial function in late middle-aged and older (50+ years) adults. They will also assess the safety and tolerability of acetate supplementation in these adults and perform innovative mechanistic analyses to determine how acetate supplementation improves arterial function. The investigators hypothesize that oral acetate supplementation will improve arterial function by decreasing oxidative stress and increasing nitric oxide bioavailability, and also hypothesize that acetate supplementation will be safe and promote high rates of adherence.
