This study will be a multi-site, single-blinded, randomized controlled trial (RCT) that will screen older adults with mild cognitive impairment (MCI) using 4 steps (over the phone, in-person interview including informed consent, medical verification, exercise stress test/magnetic resonance imaging [MRI]). We will enroll 128 participants (target 96 completers, assuming 25% attrition rate at 6 months). After baseline assessment, participants will be enrolled and randomized within age (65-74 years of age or ≥75 years of age) and study site (Minnesota or Rochester) strata centrally at the University of Minnesota (UMN) to one of four groups: ACT, cycling only, SOP only, or control with equal allocation and using a randomization scheme generated by our UMN biostatistician (CI: Vock). Group allocations will be concealed to all investigators and data collectors. The interventions will last for 6 months with 12-month follow-up. Outcomes include: 1) cognition: composite measures of executive function and episodic memory, 2) AD signature cortical thickness: composite using structural magnetic resonance imaging (MRI), 3) functional connectivity in DMN: resting-state using functional MRI (fMRI), 4) aerobic fitness, and 5) clinical and pathological AD conversion. Cognition and aerobic fitness will be assessed at baseline, 3, 6, 12, and 18 months; AD conversion at 6, 12, and 18 months; and AD signature cortical thickness and DMN at baseline, 6, 12, and 18 months. PIs Yu and Lin have developed and tested strategies in their preliminary studies to successfully ensure the protection of human participants.

This is a prospective study aimed at quantifying walking and balance in normal pressure hydrocephalus (NPH) patients in the clinical setting. To accomplish this, we will use a portable motion capture system that is widely used to study biomechanics in humans. Once quantified, we want to test the effects of ventriculoperitoneal shunt (VPS) on walking and balance among NPH patients. Thus, our objectives are: Aim 1: We will demonstrate the use of quantitative kinematic data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on gait and balance. Aim 2: We will demonstrate the use of objective, neuropsychological data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on cognition 3. We will demonstrate the use of objective, physical therapy data on NPH patients pre-lumbar drain, post-lumbar drain and post-VPS in order to assess the predictive value of CSF removal on therapeutic intervention in terms of walking and balance measures.

The purpose of this study is to better understand how tobacco and nicotine products affect our bodies. In this observational study smokers, vapers, smokeless tobacco users, nicotine replacement product users, non-users, and ex-users will be asked to provide biological samples. We will look for biological “markers” (biomarkers), or chemical changes in the body, that occur due to tobacco or nicotine exposure. Collected samples will be used for the development of biomarkers of toxicant exposure and for assessing exposure between the different groups. The intent is to eventually use these biomarkers to improve detection, prevention, and treatment strategies for tobacco-related diseases. This study will allow us to test currently used biomarkers, and to establish a biorepository (sample bank) to identify and develop new biomarkers associated with tobacco exposure and cessation. The type of samples and amount collected will depend on the specific biomarker(s) being developed or tested. Potential samples include saliva, cheek (buccal) & oral cells, blood, urine, hair, and/or nail clippings.

The effect of enzyme replacement therapy on how well your kidneys are responding to enzyme replacement therapy (ERT) is not clear from blood and urine tests alone, but may be more clear in comparisons of kidney biopsies performed before and some time after ERT has been initiated, and this is what we are focusing our study efforts on. The purpose of this study is to obtain your permission to allow us to study the kidney biopsy tissues (collected for medical reasons) after the regular routine studies have been completed. Through our special research measurements and additional study, we hope to be able to see and measure very specific changes in the kidney tissues from Fabry patients taking ERT. We also hope that through these studies of what happens within the kidney before and after starting ERT, we are able to reveal valuable information about the importance of factors like your age that you started ERT, the amount or dosage of ERT, and any differences seen between males and females.

This study will develop a platform for stimulation setting optimization based on power spectral density (PSD) measures. Randomized, controlled trials have demonstrated that stimulation of the anterior nucleus of the thalamus (ANT) suppresses seizures. The central hypothesis tested here will be that PSD measured in the ANT will correlate with seizure frequency and stimulation settings that suppress broadband activity will result in lower seizure rates.
