More than three quarter of patients with breast cancer are treated by hormone pills called tamoxifen and aromatase inhibitors (AIs). AIs are drugs that stop female hormone production. This hormone production mostly happens in fat, muscle, and breast tissue in postmenopausal women. The female hormone estrogen is an important hormone for the growth of breast cancer cells. Anastrozole (Arimidex®) and Letrozole (Femara®) are AIs that are approved by the Food and Drug Administration (FDA). They have been used since 2005 to treat women with early stage breast cancer. When given before surgery (neoadjuvant), both anastrozole and letrozole have been shown to successfully shrink breast cancer tumors in most patients. In over 50% of patients, anastrozole and letrozole when given for about 4 months also helped to improve surgery outcomes. On top of that, whether or not a patient responds to anastrozole and letrozole before surgery can help the doctor decide whether that patient needs additional chemotherapy. One of the things may influence the level of hormone is body weight. It has been previously shown that postmenopausal women with higher body fat have higher level of female hormone as well as an increased risk of breast cancer. This is likely due to an increase in aromatase activity in the fatty tissue. However, at the current time AIs are used at the same doses in all women with breast cancer no matter whether they have different body weight. Currently, we do not know for certain whether the same doses of AIs work as well in patients with higher body fat compared to patients with less body fat. The purpose of this study is to see if women with higher body fat respond differently to AI treatment compared to women with lower body fat.

Neuroimaging studies suggest that aberrant activities at specific brain regions such as sensory areas and language-related areas are related to psychosis symptoms including auditory and visual hallucination, delusion, and thought disorders. Transcranial magnetic stimulation (TMS) provides a non-invasive means for altering brain electrical neural activity. TMS has been approved by FDA for treatment of depression. Other applications have not been approved but it has been used in a wide range of clinical research especially in neurology and psychiatry. Among psychotic symptoms, there are preliminary significant improvement in treatments of auditory hallucination using TMS with small samples, but those treatments are not robust in larger samples. The high inter-subject variability limits the efficacy of TMS treatment in schizophrenia patients. We aim to develop a TMS treatment method with a fMRI-defined treatment target area, where the TMS target is individually identified to maximize the TMS effects. The identification method uses both the anatomical character and its functional relationship with auditory hallucination and other psychosis symptoms. If the current target-identification successfully identified effective TMS target individually, the treatment efficacy will be significant improved and more patients will benefit from TMS treatment.

Difficulties with communication for patients requiring mechanical ventilation is known to be a source of distress in the acute care setting. The inability to speak has been associated with increased psychological distress and increased feelings of fear and anger and impact negatively on patient participation with caregivers and their overall recovery. Developing and maintaining communication between patients and hospital staff reduces patient stress and increases patient satisfaction and part of the standard pf care. According to the new and revised The Joint Commission standards, hospitals must identify and document patients' communication needs and communicate with patients during their care in a manner that meets those needs. Using the Dolores One device for patients can improve the ease and efficiency of communication while they are in the acute care setting. For non-speaking patients, nonverbal communication means are often used, including mouthing words and head nods to indicate yes/no responses. However, relying completely on nonverbal means can limit patient responses and lead to ineffective and frustrating communication exchanges. There have been several studies reviewing the negative effects of the inability to speak for intubated, mechanically ventilated patients. However, there is a need for more research to address communication difficulties in other mechanically ventilated populations, including patients receiving non-invasive ventilation and ventilator dependent tracheostomy patients. The Dolores One is comprised of an acoustic throat sensor and positioned at the patient's neck with a soft adjustable collar. The sensor gathers vocal cord vibrations and transmits signals to a control unit, processes the sensor signal, and finally, generates the patient's voice. The smart signal processing automatically accommodates both weak forced voices and whispers, producing a voice output to allow for normal conversation in a patient's natural voice, free from the sounds of rushing air or equipment noises secondary to Non-Invasive Mechanical Ventilation (NIMV) systems. The purpose of the study is to determine if the Dolores One devices can be used in the clinical acute care setting with patients in NIMV to improve their ability to communication as measured as ease to communicate and intelligibility, with family and the members of the medical team.

Several observational studies have shown that uncontrolled hyperglycemia in hospitalized patients in the non-critical care, non-Intensive Care Unit (non-ICU) setting is associated with prolonged length of stay, increased mortality and an increased incidence of infections. Randomized clinical trials in both the critical and the non-ICU settings have shown that by improving glucose control there is a decrease in the incidence of infections, length of stay and inpatient health care costs. Continuous glucose monitoring (CGM) systems have evolved as useful devices providing excellent clinical care in patients with Diabetes Mellitus (DM). These systems detect glucose in subcutaneous interstitial fluid using a glucose sensor that transmits glucose measurements to a receiving device that reads out average glucose levels every couple of minutes. In this clinical trial the investigators propose to examine the clinical use of CGM in hospitalized patients with Diabetes Mellitus type 2 (DM2). CGM use may improve glucometric values and clinical outcomes in hospitalized individuals with Diabetes Mellitus type 2 (DM2). We use CGM devices to monitor but also to transmit glucose values wirelessly to monitoring devices that are in the nursing station. Half of the participants are placed on Real Time CGM (alarms turned on) and half of them are placed on blinded CGM values (alarms turned off). Nursing staff will be notified when glucose is <85 mg/dl , in order to treat and potentially prevent a potential hypoglycemic episode.

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.

Multiple Sclerosis (MS) is an autoimmune disorder of the central nervous system. In MS, inflammation is known to attack areas of the brain, spinal cord, and optic nerves; resulting in disability. Current MRI technology provides an adequate view of the impact of MS on the "white matter" of the brain, which contains many of the connections between neurons. Quantification of lesions in the white matter due to MS are a standard part of clinical trials and clinical care in MS. However, it has long been known that MS not only can affect the white matter, but also the "gray matter," which contains the majority of the nerve cells in the brain and can cause inflammation in the meninges (the protective tissue that surrounds the brain and spinal cord). Autopsy studies have shown that the inflammation seen in the meninges is driven by a B-cells, a subset of white blood cells and that meningeal inflammation may be responsible for damage to the gray matter of the brain. Ocrelizumab is a new treatment for multiple sclerosis. This medication works by targeting and destroying circulating B-cells. It is thought that this may reduce the level of meningeal inflammation in patients with multiple sclerosis. By reducing meningeal inflammation, this medication may result in less damage to the gray matter and subsequently less disability in MS patients. In this study, the investigators will evaluate the use of a method on 7 tesla (7T) MRI to identify inflammation in the meninges as a potential predictor of response to ocrelizumab treatment for multiple sclerosis. Further, the investigators will evaluate if this MRI technique can be used to monitor the long-term effect of the medication on meningeal inflammation and the development of damage to the gray matter of the brain.

The Wellness Champions for Change (WCC) study aims to reduce pediatric obesity among students who attend schools in Maryland by training teacher and student-led wellness teams to increase opportunities for physical activity and healthy eating at school. The study uses a cluster randomized design to allocate 6 schools (3 elementary, 3 middle) in 5 school systems to one of 3 arms: "A" (teacher and student training), "B" (teacher training only), and "C") (delayed teacher training/control). Approximately 36 3rd/6th graders and their caregivers ("evaluation cohort"), 15 4th/7th graders ("student leaders"), and 20 teachers from each school will be recruited in the spring before the intervention. All schools will identify a teacher "Wellness Champion" who will coordinate intervention activities. In "A" and "B" schools, wellness champions will attend a training to learn how to build a wellness team and create more opportunities for students to make healthy choices. In "A" schools, student leaders ("Student Wellness Champions") will meet weekly during lunch with a health educator to receive training as peer leaders and help the Wellness Champion with wellness initiatives. Student leaders in "B" and "C" schools will receive a monthly general Adolescent Health Curriculum. To assess the impact of the teacher and student-led interventions, the evaluation cohort will be followed for 2.5 years, with measures including: anthropometry (height/weight), 7-day accelerometry (physical activity), and validated questionnaires to assess healthy eating. Student leaders will be followed for 1.5 years to assess the impact of their participation, with measures including: anthropometry, 7-day accelerometry, validated questionnaires to assess healthy eating, and validated questionnaires and focus groups to assess leadership/advocacy skills. Teachers will complete validated questionnaires to investigate their perceptions of the school environment, classroom practices, and role modeling skills. Prior to data collection and analysis, participants will be assigned an identification number, and all documents linking participant information to identification numbers will be locked/ password-protected.

Falls and their consequences are among the major problems in the medical care of older individuals. The long-term goal of this research is to develop a mechanistically based therapeutic intervention to enhance muscle power, weight-shifting capability, and lateral balance function through protective stepping to prevent falls. When human balance is challenged, protective stepping is a vital strategy for preventing a fall during activities of daily life. Many older people at risk for falls have particular difficulties with successfully stepping sideways as a protective response to loss of balance in the lateral direction. Age-related declines in lateral balance function result from neuromuscular and biomechanical limitations in hip abductor-adductor muscle power generation. This study will test whether these impairments can be improved with high-velocity hip muscle resistance power training that will be more effective than conventional resistance strength training.

Stroke is the leading cause of long-term disability in the U.S. Individuals with hemiparesis due to stroke often have difficulty bearing weight on their legs and transferring weight from one leg to the other. The ability to bear weight on the legs is important during functional movements such as rising from a chair, standing and walking. Diminished weight transfer contributes to asymmetries during walking which commonly leads to greater energy expenditure. Moreover, deficits in bearing weight on the paretic leg contribute to lateral instability and are associated with decreased walking speed and increased risk of falling in individuals post-stroke. These functional limitations affect community participation and life quality. Thus, restoring the ability to bear weight on the legs, i.e., limb loading, is a critical goal for rehabilitation post-stroke. The purpose of this research is to identify the impairments in neuromechanical mechanisms of limb loading and determine whether limb loading responses can be retrained by induced forced limb loading.

Periodontal Disease (PD) is present in 60+% of adults >65 years and is associated with tobacco smoking, diabetes, and atherosclerosis that worsen inflammation, comorbidities common in older people with mild to moderate cognitive impairment (MCI). Older MCI patients are prone to poor oral hygiene and dental health, which if untreated worsens inflammation-mediated brain and nervous system function, and accelerates progression to dementia. Asymptomatic carotid artery stenosis (ACAS) is often a silent disease detected in only ~10% of older adults, and may have a strong association with MCI. This study examines the effects of intensive therapy for periodontitis on cognition in high-risk older people with ACAS. Results could highlight PD as a readily modifiable risk factor for dementia.

Osteoarthritis (OA) in the knee is characterized by chronic inflammatory pain that is not necessarily related to the amount of joint damage. Clinical practice guidelines recommend physical activity (PA) for osteoarthritis pain, but most adults with OA do not engage in PA. One reason for this is that while PA can reduce OA related joint pain, it does not work for everyone. PA decreases pain sensitivity for about half of adults with OA but increases pain sensitivity for the other half. The investigators are hypothesizing that individual differences in how well cells work to make energy, inflammation, and different proteins available in blood cells explains who PA will work to reduce pain and who it won't among adults with OA. The purpose of this pilot study is to determine if blood cells' ability to make cellular energy, inflammation and proteins help explain the difference about who PA reduces activity for and who it doesn't. The investigators will compare these biologic factors and pain sensitivity before walking, immediately after 30 minutes of walking (i.e. "acute") and after six weeks of walking three times a week for 30 minutes (i.e. "long-term") in adults with hip or knee osteoarthritis. The investigators will also compare these results to adults without OA. The investigators will recruit a sample of 40 adults with radiologic (e.g x-ray or CT scan) evidence of hip or knee OA and 20 age/gender matched healthy adults without OA to address the following study aims: Aim 1: To examine the effects of a six week (three days/week) walking program on pain in adults with OA as compared to healthy controls. Aim 2: To test the cells' ability to make energy as a mechanism for variation in pain after "acute" and "long-term" PA in older adults with lower extremity osteoarthritis. Aim3: To test the role of inflammation as a mechanism for variation in pain after "acute" and "long-term" physical activity in adults with lower extremity osteoarthritis. Aim 4: To generate hypotheses regarding the role of proteomics in variation in pain after "acute" and "long-term" physical activity.
