This clinical trial tests the safety and effectiveness of a single-dose treatment of biology-guided radiation therapy (BgRT) in treating patients with painful cancer that has spread from where it first started (primary site) to the bone (bone metastases). Bone metastases can result in significant pain and reduction in quality of life. Single fraction radiation therapy (SFRT) can produce equivalent pain relief compared to multi-fraction radiation therapy, but SFRT treatments generally lead to higher rates of retreatment. BgRT is a new and innovative form of radiation delivery that uses a signal generated by positron emission tomography to guide external beam radiation therapy. It is a technology breakthrough that uses live, continuously updated data throughout the entire treatment session to determine exactly where to deliver radiotherapy to biologically active tumors. Giving BgRT may be safe and effective in treating patients with painful bone metastases. Read Less

This clinical trial evaluates whether using aromatherapy can reduce pain and anxiety for cancer patients during routine biopsy procedures. Because of the discomfort associated with a bone marrow aspirate and biopsy (BMAB), many patients have significant anxiety in addition to their pain. With the current background of the opioid crisis, researchers have been looking for different ways to treat pain and anxiety in cancer patients without using medications that have a risk for abuse. Recent research suggests that using lavender aromatherapy may be an effective and more affordable treatment for anxiety and pain in patients. Information gathered from this study may help researchers determine whether using aromatherapy may help to manage pain and anxiety during biopsy procedures for cancer patients. Read Less

Specific Aim 1: To further quantify the difference in the sensorimotor cortical activity, spinal cord activity, and corticospinal coherence of persons with CP. Overall hypotheses: The sensorimotor cortical activity, spinal cord activity, and corticospinal coherence will be uncharacteristic in persons with CP when compared with neurotypical controls. Furthermore, the extent of the alterations in the sensorimotor cortical activity, spinal cord activity, and corticospinal coherence will be tightly linked with the clinical presentations of persons with CP. Specific Aim 2: To investigate the effect of transcutaneous current stimulation applied over the cortex and/or spinal cord on the sensorimotor cortical activity, spinal cord dynamics, and corticospinal coherence. Overall hypotheses: Compared with the sham controls, those receiving the transcutaneous current stimulation will demonstrate alterations in the strength of the sensorimotor cortical activity, spinal cord activity, and corticospinal coherence. Moreover, the extent of the alterations in the sensorimotor cortical activity, spinal cord activity, and corticospinal coherence will be tightly linked with the clinical presentations of persons with CP.

Exercise is a cornerstone of diabetes management. It helps reduce blood pressure, promote weight loss, lower insulin resistance and improve glucose and lipid (triglyceride and HDL-cholesterol) profiles. Unfortunately, the benefits of exercise are often not embraced by diabetic individuals because of the fear of low blood sugar (hypoglycemia). My laboratory has demonstrated that Autonomic nervous system (ANS) counterregulatory failure plays an important role in exercise associated hypoglycemia in Type 1 DM. ANS responses are significantly reduced in Type 1 DM and are further blunted by antecedent episodes of hypoglycemia. Furthermore, there is a large sexual dimorphism of reduced ANS responses during submaximal exercise in both Type 1 DM and healthy individuals that is unexplained. Accumulating data are demonstrating that serotonergic pathways can regulate ANS discharge. Generally, serotonergic pathways are inhibitory but both single and longer term administration of selective serotonin reuptake inhibitors (SSRI's) such as Prozac has been demonstrated to increase basal epinephrine levels and enhance baroreflex control of Sympathetic nervous system (SNS) activity. What is unknown is whether fluoxetine can also enhance SNS responses and also override the large ANS sexual dimorphism present during sub maximal exercise. Therefore, the purpose of this study is to determine if the SSRI fluoxetine (Prozac) can improve SNS responses during exercise. Read Less

This study aims to investigate genetic causes of early childhood obesity. The investigators will enroll children and adults with severe early onset obesity (BMI \> 99th percentile) diagnosed prior to 6 years of age. The investigators will ask questions about the health and eating behavior of the participants, and perform a brief physical examination. The investigators will collect saliva or blood to perform genetic testing from the participants and invite family members to enroll in the study. Read Less

Hypoglycemia can produce a spectrum of pro-inflammatory and pro-atherothrombotic changes. To date no studies appear to have investigated the effects of differing levels of hypoglycemia on the vasculature and pro-atherothrombotic balance during hypoglycemia in healthy man. The specific aim of our study will be to determine the effects of differing levels of hypoglycemia on in-vivo vascular biologic mechanisms in a healthy population. Read Less

Rapid onset Obesity, Hypoventilation, Hypothalamic dysfunction and Autonomic Dysregulation (ROHHAD) is a syndrome named in 2007. The hallmark of the syndrome is the rapid onset obesity and dysregulation of central ventilation. There is little information about the metabolic changes that lead to the rapid onset obesity in these children. The investigators would like to study the metabolic phenotype of these children to understand the disturbances in energy balance that lead to the rapid onset obesity. Read Less

Epinephrine is the principal physiologic defense against hypoglycemia in type 1 and longer duration type 2 DM. Despite this, it is unknown how epinephrine regulates in-vivo endothelial function and atherothrombotic balance in humans. The specific aim of our study will be to determine the dose response effects of the key ANS counterregulatory hormone epinephrine on endothelial function, fibrinolytic balance and pro-atherogenic inflammatory mechanisms in healthy humans.
