The ultimate goal of this study is to develop non-invasive, painless repetitive transcranial magnetic stimulation (rTMS) protocols to prevent cognitive decline in patients with mild cognitive impairment (MCI) and cognitively normal individuals at high risk of developing Alzheimer's disease (AD). Currently, 1 in 9 adults over the age of 65 have AD, which currently totals more than 5 million Americans and this number is expected to rise as high as 16 million by 2050. MCI is a clinical syndrome that represents the gray area between healthy aging and dementia. Those with amnestic MCI (aMCI) have memory problems more severe than normal for their age and education, but their symptoms are not as severe as those of people with AD. Patients with aMCI are at high risk for AD. Notably, roughly half of those with MCI will continue to progress and convert to clinical dementia within 3 years. Alternatively, it is also worthwhile to study cognitively healthy older adults who carry genes that may increase the risk of AD. The frequency of the human APOE gene ε4 allele increases in patients with AD and the ε4 allele is also associated with an earlier age of disease onset. Currently, there are no known therapies that can effectively modify the progression and hallmark symptoms of AD. Therefore, it is crucial to provide an early intervention in patients with aMCI to delay or prevent the progression to AD. More specifically, this project has two specific aims: To plan personalized non-invasive brain stimulation location by brain Imaging with Magnetic Resonance Imaging (MRI) in Mild Cognitive Impairment (MCI) To identify potential personalized cognitive enhancement strategy (such as dosage or patterns) of Transcranial Magnetic Stimulation (TMS) in MCI. Techniques to artificially and precisely stimulate brain tissue are increasingly recognized as valuable tools both in clinical practice and in cognitive neuroscience studies among healthy individuals and people with clinical conditions. With these practices, researchers can safely stimulate specific regions of the brain to explore causal relationships that comprise the brain's circuitry and modulate behavior. Read Less

Traumatic brain injury (TBI) is a leading cause of death among trauma patients accounting for one-third of all trauma mortalities. Patients who survive the initial trauma are liable to secondary insults from the ensuing inflammatory state in the brain. Treatment goals are aimed at reducing secondary injury. Maintaining adequate brain perfusion, limiting cerebral edema, and optimizing oxygen delivery are part of established treatment protocols. Numerous therapeutics have been evaluated as potential treatment for TBI with very limited success and there is no medication that alters survival. Various novel therapeutic options have been investigated to prevent the secondary brain injury. Remote Ischemic Conditioning (RIC) is one of these therapies. RIC involves decreasing blood flow to a normal tissue usually the arm by inflating the blood pressure cuff 30mmHg over the systolic blood pressure. The decreased blood flow or ischemia is maintained for 5 minutes followed by releasing the pressure and re-perfusion of the arm. This cycle is usually repeated 4 times. RIC has been shown to improve outcomes in patients with heart attacks, strokes, elective neurosurgeries. A prospective observational study and a randomized clinical trial has shown the protective effect of RIC in TBI patients. Additionally, multiple studies in animals have shown that RIC is neuroprotective after TBI. RIC is non-invasive and harmless except for a little discomfort in the arm. The aim of the study is to evaluate the impact of RIC on long term outcomes in patients with TBI. Read Less

The aims of this study are to compare 3 different treatments for circadian adjustment to a laboratory protocol which will mimic westward air travel across 8 time zones. One treatment will involve simply following the new schedule for 3 days. Another treatment will also involve exposure to bright light for 1 hour per day. A third treatment will involve exposure to bright light + exercise for 1 hour per day + consuming a melatonin tablet. Adjustment to the shifted schedule will be assessed by comparing measures of sleep, mood, mental performance, physical performance, and timing of melatonin across the 3 treatment conditions.

This is a two-part study designed to evaluate the effect of Estetrol (E4) 15 or 20 mg, or placebo on the severity and frequency of vasomotor symptoms (VMS) (Efficacy Study Part) and the safety of E4 20 mg (Endometrial and General Safety Study Part) Read Less

Higher education is crucial for young adults in their intake of knowledge and skills to further their careers and reach their potentials. However, going through college is not necessarily an easy path. The purpose of this study is to enhance university students' well-being and educational experience by examining factors associated with stress and well-being. The investigator plans to recruit eighty participants from a large public university in the US to provide survey data and saliva samples at two waves during the data collection semester (beginning and end of the semester). Survey data will include demographic information and help gauge psychosocial factors related to stress and well-being. Saliva will be tested for two biomarkers each wave of data collection, cortisol (sampling three times a day for diurnal patterns for two consecutive days) and c-reactive protein, which indicate physiological stress/immune responses. Additionally, participants be randomly assigned to an intervention (n = 40) or control group (n = 40), where the intervention group will undertake a brief intervention focused on motivation and emotion regulation circa mid-semester and the control group will receive a placebo goal-setting short training. The investigator aims to examine whether intervention efforts can enhance end-of-semester psychological and physiological well-being, and particularly, whether students from diverse backgrounds (e.g., first-generation, low-income, and/or BIPOC) can benefit from the intervention. The investigator will use advanced quantitative data analysis (using Mplus v.8, in a structural equation modeling framework) to examine intervention efficacy and group differences. The investigator hypothesizes that those receiving the intervention will display a healthier profile at the end of the semester compared to their control group counterparts; and the investigator hypothesize students from diverse backgrounds will have significantly improved results from the intervention. The study will allow a better understanding to crucial steps towards exploring how to improve the well-being, higher-education pipeline, and retention of students with diverse backgrounds, providing insight on how each student's university experience can be improved.

Viruses are a major health problem for the general public and at risk populations. Normally, detection of antibody titers is the gold standard for determining the effectiveness of the immune system following natural or vaccine caused immunization. However, determining the effectiveness of other parts of the immune system are less common due to the difficulties with testing. Furthermore, there is a critical need to address other therapies in case vaccination is not successful in immuncompromised populations. Exercise has been shown to increase the strength of the immune system against many types of viruses and therefore could be simple way to improve immunity against the COVID-19 virus. The aim of this research is to determine the effects of exercise on anti-viral immunity against many types of common viruses before and after vaccination. We hypothesize that exercise will enhance the anti-viral immunity before and after vaccination. Up to 30 healthy volunteers (age 18-44 years) will be recruited to participate in this study. For completion of Aim 1, three visits are needed totaling around 7 hours of the patient's time and for Aim 2, three visits are needed totaling around 4.5 hours of the patient's time. The initial visit will be for pre-screening and if deemed healthy enough to participate, an exercise test to determine the VO2 max of the participant will be conducted. The following visits will require a trained phlebotomist to insert an in-dwelling catheter and participants will undergo a 20-minute incremental exercise trial. Approximately 50mL of blood will be collected at four different timepoints: at rest, 60% VO2 max, 80% VO2 max, and 1-hr post-exercise. All four collected blood samples will be used to expand viral specific T-cells and compare IFN-γ rele Read Less
