Clinical trials

The goal of this clinical trial is to determine whether the extra-virgin olive oil (EVOO) phenolic dietary supplement can improve memory function and modulate biomarkers among individuals with mild cognitive impairment (MCI). The main questions it aims to answer are: * Does dietary supplementation with EVOO phenolics improve cognitive function? * What would be the effect of the EVOO dietary supplement on other MCI-related biomarkers, including vascular function and biological pathways? Researchers will compare the EVOO dietary supplements with a placebo (a look-alike substance that contains no EVOO phenolics) Participants will: * Take EVOO dietary supplements or a placebo daily for 6 months * Visit the study site during the 6-month study for screening and testing.

The purpose of this proposal is to understand how the Vibrant Health Ultimate whole-body vibration (WBV) machine affects pain and inflammation in older adults. The investigators' hypothesize that sub-acute (12 weeks) WBV will lead to improvement in the level of knee pain and improve vascular function via a decrease in systemic inflammation.

The goal of this study is to assess the efficacy of induction treatment with daratumumab-hyaluronidase (dara SC) with cyclophosphamide, bortezomib, and dexamethasone (Dara-CyBorD) for four cycles in patients with newly diagnosed multiple myeloma who have new onset renal failure. This study will also investigate the difference responses in African American (AA) patients versus non-African American patients. The primary questions this study aims to answer are: 1. To evaluate the very good partial response rate (VGPR) after 4 cycles of Dara-CyBord. 2. To evaluate the renal response rate (RRR) after 4 cycles of Dara-CyBord.

The purpose of this study is to test a new procedure to treat Alzheimer's disease. The procedure is called intermittent Deep Brain Stimulation (DBS) of the nucleus basalis of Meynert. There will be up to six participants enrolled at Wellstar MCG Memory Clinic. There will be another six participants similarly enrolled to act as a control group that does not receive DBS. This second group will document the course of progression of Alzheimer's disease under the normal standard of care. The main goal of the study is to determine if DBS can sustain or improve cognition in Alzheimer's disease for at least two years. Participant data, with identifying information removed, may be shared with online repositories for comparison with trials with similar subjects.

Preterm and very low birth weight (VLBW, \< 1,500g) infants who receive donor human milk (DHM) often experience slow postnatal growth and no clinical data is available to guide the duration of DHM for preterm infants. The investigators hypothesize that transitioning from DHM to preterm infant formula after the first month of life is both safe and conveys improved weight and length gains and fat free mass accumulation.

The goal of this clinical trial is to learn if "prescribing" afterschool care to children at risk for poor heart health later in life increases their physical activity and improves their heart health. 'Prescriptions' will be provided by pediatricians at participating Federally Qualified Health Centers and vouchers to existing afterschool programs (e.g., YMCA, Boys and Girls Clubs) will be provided by the research study. The main questions this study aims to answer are: Can afterschool care providers and health care providers easily offer and keep using the voucher program? Will families use the voucher? Do they go to afterschool care regularly, and do the families who use them represent a wide range or backgrounds? Does going to afterschool care help children be more physical activity? Does going to afterschool care improve heart health? Researchers will compare two randomly assigned time periods; one semester when families get the voucher and one semester where they do not. They will look at whether use of the afterschool care voucher leads to more physical activity and improved heart health.

The goal of this clinical trial is to assess whether a seven-day course of standard of care (echinocandin) antifungal therapy is non-inferior to a 14-day course of echinocandin antifungal therapy in patients with uncomplicated candidemia in terms of clinical, mycologic, adverse events and all cause mortality.

Sugammadex is a medication used for reversal of muscle relaxation during procedures under general anesthesia. It works by encapsulating muscle relaxant molecules with a steroid ring in its structure. On the other hand, postoporative nause and vomiting (PONV) is an adverse outcome during anesthesia. PONV can be prevented with pharmacologic agents such as ondansetron and dexamethasone. Dexamethasone is a steroidal agent that can interact with sugammadex. In theory, this interaction could lead to reduced effectiveness of sugammadex. In fact, several studies have explored this interaction. However, the effect of sugammadex on the antiemetic effect of dexamethasone has not been evaluated. This study intends to evaluate this interaction.

1. The aim of this study is to assess anxiety in pediatric patients preoperatively, perioperatively, and postoperatively and whether meditation reduces anxiety in the days before, during, and after the surgery. 2. The second aim of this study is to see if longitudinal meditation is associated with decreased postoperative pain by examining whether the group prescribed meditation has reduced pain medication intake, measured by the frequency of liquid analgesic medicine intake.

The overall purpose of this pilot study is to assess the feasibility and acceptability of an in-person faith-based intervention to help people stop tobacco use. The study will address use of different types of tobacco products, such as smoking combustible cigarettes, cigarillos and little filtered cigars, and using/vaping electronic nicotine delivery systems (vape pens, e-cigs, and JUUL). The intervention consists of 12 weekly meetings in which participants will go through BREATHE Free, a study guide curriculum designed to teach character strengths and promote resilience. This pilot research will provide information and practical lessons on how to improve Breathe Free implementation, increase engagement of the local people, and maximize their benefit. The main questions it aims to answer are: * Do participants find BREATHE Free curriculum acceptable, engaging and helpful to stop tobacco use? * Do participants who complete BREATHE Free curriculum smoke fewer cigarettes per day? Researchers will assign participants to either BREATHE Free curriculum or usual care. Participants will: * Be taught BREATHE Free curriculum or be given information and referral to tobacco quit line * BREATHE Free group will attend 12 group meetings held on the university campus * All participants will answer interview questions related to tobacco use, character strengths and resilience * Expired Carbon Monoxide (CO) will be assessed in all participants.

We propose to perform NGS and OGM with DNA extracted from bone marrow (BM; site of cancer) and NGS on skin fibroblast DNA (proxy for germline) on all patients with hematologic malignancies (HM) who undergo a standard-of-care BM biopsy at Georgia Cancer Center/Wellstar MCG Health. Simultaneous 4 mm punch skin biopsy for fibroblast culture will be obtained at the planned puncture site of the BM biopsy. The bone marrow biopsy and aspirate are already part of the patient's scheduled medical evaluation and the punch biopsy of the skin is the only additional procedure involved in the study.

The purpose of this study is to determine the effectiveness of a physician led, multi-disciplinary approach to treating obesity that incorporates nutrition (mainly, using genetics to identify appropriate food intake), exercise, and motivational counseling. The investigators plan to recruit overweight/obese (BMI\>25) males and females to participate. Participants will be randomized to receive a personalized diet plan, or a standard care diet plan; both groups will participate in the exercise intervention. For a 6-month duration, both groups will be asked to improve their diet according to their dietary plan and participate in moderate-to-vigorous physical activity (gradual increase up to 300 min/week). The investigators intend to evaluate standard outcomes of weight loss, and assess for any predictors of positive outcomes. Following the six-month intervention, participants will complete a 3-month no contact phase. This no contact phase will provide insight into the effects of the study on weight loss maintenance. Our team also plans to address acceptability by providing evaluations to study participants and conducting interviews with a small subset of participants to improve the intervention for the future.

The overall goals of this pilot investigation are to determine 1) the feasibility of conducting home based WBV studies, and 2) to determine if sub-acute home based WBV can improve a) exercise capacity, b) conduit- and micro- vascular function, and c) skeletal muscle function.

The proposed study is designed to test the hypothesis that treatment of resveratrol for 12 weeks will improve both endothelin-B receptor (aim 1) and skeletal muscle mitochondrial function (aim 2) in people with type 1 diabetes.

Patients who receive a chemotherapy called melphalan are at high risk of having nausea and vomiting. A medication called olanzapine has been shown to decrease nausea and vomiting after chemotherapy. A previous research study found the 10 mg dose of olanzapine (combined with 3 standard medications used routinely to prevent nausea/vomiting) to be effective for patients who received melphalan chemotherapy, but several other studies have shown many patients have a side effect of sleepiness (e.g., sedation) with that dose of the medication. Our study will compare two lower doses of olanzapine (5 mg and 2.5 mg) in combination with the 3 standard medications used to prevent nausea/vomiting in the patients who receive melphalan chemotherapy to determine which dose is effective in preventing nausea and vomiting with the lowest amount of sleepiness side effect.

The goal of this clinical trial is to explore the effects of virtual reality use on maximal aerobic exercise test performance (aerobic capacity) in healthy adults. The main questions it aims to answer are: * Does using a virtual reality program during a maximal aerobic exercise test lead to differences in VO2peak (maximal aerobic capacity)? and, * Does using a virtual reality program during a maximal aerobic exercise test lead to differences in work rate at the ventilatory threshold? Participants will complete a maximal aerobic exercise test two times (separated by 1 week of recovery) under the following conditions: * normal testing conditions in a lab * while viewing a virtual reality video Researchers will compare the test results of both conditions to see if the use of a virtual reality program alters VO2peak or the ventilatory threshold.

Biofeedback therapy is an effective treatment for the management of patients with dyssynergic defecation and constipation, urinary incontinence (UI), and fecal incontinence (FI). It is labor-intensive, costly, requires multiple office or hospital visits, is not easily available to the vast majority of patients in the community, and is not covered by many insurance companies. The purpose of this study is to 1. Evaluate home biofeedback therapy for patients with either constipation and dyssynergic defecation or urinary leakage or stool leakage by assessing the efficacy and safety of a wireless anorectal biofeedback device, and a cellphone app-based and voice guided home biofeedback training system 2. To compare the efficacy and safety of home biofeedback therapy system with the standard of care, office biofeedback therapy 3. To assess the cost-effectiveness of home biofeedback therapy.
