Individuals diagnosed with metabolic syndrome are at a two-fold risk for developing cardiovascular disease. The investigators must identify strategies that can abort the development of cardiovascular disease. Inflammation and oxidative stress responsible for the pathogenesis of metabolic syndrome and CVD can be influenced by dietary changes. Strategic and novel interventions that include changing dietary patterns to include more antioxidant rich fruit and vegetables are pragmatic for primary prevention of CVD. Antioxidant rich fruits and vegetables, especially those with carotenoids (lycopene, lutein, zeaxanthin, alpha-carotene, and beta-carotene) have been efficacious in reducing the risk of CVD by decreasing inflammation and oxidative stress. The purpose of this study is to test the effect of a dietary antioxidant intervention on biomarkers of inflammation and oxidative stress in persons diagnosed with metabolic syndrome. The sample will be randomized into one of two groups. Group one (intervention) will drink an 11.5 ounce serving of V8 100% vegetable juice once per day for 30 days. The second group (control) will continue to consume their normal diet. We will measure biomarkers of inflammation (C-reactive protein) and oxidative stress (malondialdehyde) in the two groups at baseline and the end of the 30-day intervention.

This research study is to find out if brain stimulation at different dosage level combined with an efficacy-proven rehabilitation therapy can improve arm function. The stimulation technique is called transcranial direct current stimulation (tDCS). The treatment uses direct currents to stimulate specific parts of the brain affected by stroke. The adjunctive rehabilitation therapy is called "modified Constraint-Induced Movement Therapy" (mCIMT). During this therapy the subject will wear a mitt on the hand of the arm that was not affected by a stroke and force to use the weak arm. The study will test 3 different doses of brain stimulation in combination with mCIMT to find out the most promising one.

Endothelial dysfunction and defective placental vascularization are hypothesized to be significant causes of preeclampsia. In preeclampsia, due to vascular endothelial dysfunction, vasoconstriction and platelet activation can result in severe features which alter pregnancy outcomes. However, studies have shown that acetylsalicylic acid (Aspirin) can decrease endothelial dysfunction leading to decreased platelet aggregation which reduces adverse outcomes. The objective of our study is to determine if Aspirin has a dose-dependent response for modifying biomarkers reflective of maternal endothelial dysfunction when indicated for preeclampsia prevention in a cohort of women identified at risk for developing preeclampsia. Pregnant women who are at risk for preeclampsia will be randomized to receive either 81mg Aspirin or 162mg Aspirin daily starting from 11-16 weeks of gestation until 36 weeks of gestation. A third, control group of women at low risk for preeclampsia will not receive aspirin. All women will be assessed with uterine artery Doppler studies and mean arterial blood pressures at three time points during pregnancy. Blood, urine, and cord blood samples will also be collected.

Onabotulinum toxin type A (BoNT-A) is a potent neurotoxin that has been reported to have an effect on afferent (sensory) neurons independent of its action on muscle tone and secretory glands at the periphery.In human studies, the use of BoNT-A has proven to reduce the severity and intensity of attacks in chronic tension type headaches and chronic neck pain. The PREEMPT study concluded that BoNT-A could be used as a preventive therapy in chronic migraine patients and FDA approval was obtained. According to the International Association for the Study of Pain (IASP), BoNT-A is recommended for the management of peripheral neuropathic pain with subcutaneous administration of 50-200 units (50-200U) to onabotulinum toxin A to the painful neuropathic area every 3 months as a third line of treatment. To our knowledge, there are no clinical trials published investigating the effect of intraoral administration of BoNT-A in continuous dentoalveolar neuropathic pain. The aim of this pilot study is to investigate the potential therapeutic effect of intraoral administration of BoNT-A in patients suffering from continuous neuropathic pain. HYPOTHESIS: There will be statistically significant differences in reported pain intensity after the intraoral administration of BOTOX® in patients suffering from chronic continuous dentoalveolar neuropathic pain. A single subject experiment will be conducted with 10 patients where 50 U of BonT-A will be injected into the painful dentoalveolar area. Eligible subjects will complete a pain diary indicating their pain intensity by means of a visual analog scale during one month to establish a baseline. After the first injection, subjects will continue to monitor the VAS daily for 3 months and the infiltration will be repeated a second time following the same protocol. Patient's response will be monitored with the daily pain diary.

Eligible untreated patients with FLT3 acute myeloid leukemia (AML) between the ages of 18 and 65 will be randomized to receive gilteritinib or midostaurin during induction and consolidation. Patients will also receive standard chemotherapy of daunorubicin and cytarabine during induction and high-dose cytarabine during consolidation. Gilteritinib, is an oral drug that works by stopping the leukemia cells from making the FLT3 protein. This may help stop the leukemia cells from growing faster and thus may help make chemotherapy more effective. Gilteritinib has been approved by the Food and Drug Administration (FDA) for patients who have relapsed or refractory AML with a FLT3 mutation but is not approved by the FDA for newly diagnosed FLT3 AML, and its use in this setting is considered investigational. Midostaurin is an oral drug that works by blocking several proteins on cancer cells, including FLT3 that can help leukemia cells grow. Blocking this pathway can cause death to the leukemic cells. Midostaurin is approved by the FDA for the treatment of FLT3 AML. The purpose of this study is to compare the effectiveness of gilteritinib to midostaurin in patients receiving standard combination chemotherapy for FLT3 AML.

Complete pelvic and para-aortic lymphadenectomy performed at the time of primary surgical staging for endometrial cancer increases operative time and surgical morbidity, but appears to be necessary in most high grade and deeply invasive cancers. To date, the Mayo Clinic approach has not been reproduced, and the investigators propose to validate their algorithm at the University of Kentucky utilizing intra-operative consultation (IOC). The preliminary data at the University of Kentucky for IOC and endometrial cancer outcomes suggest that the investigators are well-suited to perform this investigation. A surgical approach that is tailored to the patient's cancer biology is rational, supported by the recent literature, and medically compelling since the co-morbidities of many obese, low-risk EC patients put them at significantly increased perioperative risk for complete lymphadenectomy.

Background and justification: Nearly 29 million Americans (9.3% of the population) have type 2 Diabetes Mellitus (T2DM) and another 86 million are considered prediabetic, 20-30% of whom will develop diabetes within five years.4,5 T2DM disproportionately affects those from lower socioeconomic status (SES) and rural backgrounds. Appalachian residents represent an extreme version of this already vulnerable population, with rates of diabetes 46% higher than national averages.6,7 The investigators have developed, pilot tested (N=41) and refined (N=48 in-depth interviews, 4 focus groups with 31 participants, and 2 CAB meetings with 16 members), a culturally appropriate, feasible, and promising intervention that combines diabetes self-management education and tailored patient navigation intervention., Goal: Our goal focuses on reducing HbA1c, BMI, blood pressure, lipids, and waist circumference and improving T2DM self-management and clinic attendance. Leveraging local assets, including faith communities, local health facilities, trained community health workers, and social support, the investigators will expand a promising and refined pilot study and assess outcomes, satisfaction and cost effectiveness. Innovation and impact: The proposed project is among the first RCT to combine the two most influential approaches to diabetes control-- self-management education and tailored patient navigation in a community setting. The Community to Clinic Navigation (CCN) intervention has the potential to sustainably empower hard to reach populations with effective self-management education and enhance the quality of healthcare in traditionally underserved communities, greatly improving T2DM outcomes.
