Neurologic disease with loss of motor function is a major health burden. Brain-computer interfaces (BCI) are systems that use brain signals to power an external device, such as a communication board or a prosthetic device, which may help people with loss of motor function. Electrocorticography (ECoG) has been used to decode hand movements and as a control signal for brain-computer interface (BCI). This study hopes to use a smaller spacing of ECoG to see if a better motor signal can be found and used as a BCI control signal. Read Less

This observational study collects data on blood neurotransmitter and neuromodulator levels of subjects observing Ramadan. Additional information collected are a diet record, mood and perceived stress using validated surveys at three time points: a) before starting Ramadan, b) at the midpoint evaluation, and c) at the end of Ramadan. Three additional dispositional factors collected at the beginning and at the end are: a) sense of belonging, b) purpose in life (sense of coherence), and c) empathy (interpersonal reactivity index). The subjects are also individually interviewed on their experience of Ramadan as narrative data. Read Less

The use of implantable left ventricular assist devices (LVAD) has increased over the last decade; partly because the newer continuous flow pumps feature a smaller design and better durability. These pumps have shown improved outcomes for those patients who don't qualify for heart transplantation and receive the LVAD device as a permanent therapy or a bridge to heart transplantation. Despite these improved outcomes, procedure related length of hospitalization for LVAD implantation is still 2 or 3 times that of other heart surgery treatments. One important reason for this is that many people experience right ventricular dysfunction after LVAD implantation. Treatment options for this are limited. Many LVAD patients with right ventricular dysfunction also have tricuspid valve regurgitation (TR). This is the failure of the tricuspid valve (TV) to close completely so that blood leaks backwards. Some recent studies suggest that correction of the TV during LVAD implantation has improved survival for those with severe regurgitation. However, this has not been evaluated for mild or moderate regurgitation. The goal of this study is to look at the clinical impact of surgical correction of mild to moderate TR in participants who are also undergoing LVAD implantation. The study will look at the degree of TR at various time points post-surgery, as well as any major cardiac adverse events, duration of hospitalization, and quality of life. The investigators hope to show that surgical correction of mild to moderate TR in LVAD patients will reduce right ventricular dysfunction and have a positive impact on health outcomes. Read Less

The present study D5272C00001 (Legacy # 3151-201-008) seeks to evaluate the efficacy and safety of brazikumab versus placebo in patients with moderately to severely active UC and will include assessments of clinical responses as demonstrated by improvement of symptoms and of colonic mucosal appearance as observed on endoscopy.

Sagittal split osteotomy (SSO) is a common operation done to move the mandible to correct dentofacial deformities and obstructive sleep apnea (OSA). Inferior alveolar nerve (IAN) injury and associated paresthesia is a well-known negative outcome following SSO, causing temporary or sometimes, permanent numbness in the chin and/or lip. There are limited methods to decrease the occurrence and duration of neurosensory dysfunction. Recent research has shown that platelet-rich fibrin (PRF) aids neurosensory recovery after SSO. Another method to minimize nerve injury is proximal segment grooving (PSG) to create space for the nerve to rest. This grooving method has never been formerly reported. The purpose of this study is to answer the following question: Among patients undergoing bilateral sagittal split osteotomy (BSSO) for dentofacial deformity or OSA, do those who receive PRF with or without PSG, compared to those who do not, have shorter times to functional sensory recovery (FSR) of the IAN? The null hypothesis is that there is no difference among 4 treatment groups and neurosensory outcomes. The specific aims of this proposal are to 1) enroll and randomize subjects who will undergo BSSO for correction of dentofacial deformity or OSA into 4 different treatment groups (PSG with PRF, PSG alone, PRF alone, neither PSG or PRF), 2) measure objective and subjective post-operative nerve function at fixed intervals post-operatively for up to 1 year, 3) compare differences in neurosensory outcomes among treatment groups, and 4) identify other variables that might be associated with differences in neurosensory outcomes.

Rationale: Low back pain (LBP), or myofascial pain syndrome (MPS) of the low back, accounts for approximately 2.63 million visits in the United States, or 2.3 percent of annual Emergency Department (ED) visits. An estimated 100 billion dollars per year is lost from LBP. Approximately one-third of this is direct costs. Previous studies have established the safety of trigger point injections (TPI). However, the results of these studies are highly heterogeneous regarding TPI's ability to treat pain or improve functional outcomes. The two most promising TPI studies conducted in the ED have been published in the last two years. They both suffered from a small sample size. Additionally, they suffered from a combination of limitations including: lack of randomization, inconsistent medical management, lack of a follow-up assessment, and lack of patient centered functional outcomes. These studies were both two armed and either compared standard medical management to TPI with local anesthetic or TPI with local anesthetic to TPI with Normal Saline (NS). One of these studies concluded that TPI is generally beneficial. The other concluded that TPI with NS is superior. Research Hypothesis: The investigators hypothesize that standard therapy (ST) plus TPI with 8 mL of 0.5 percent Bupivacaine is superior to ST alone or ST plus TPI with 8 mL of NS for the treatment of the pain associated with MPS of the low back. Significance: This will be the first TPI study to compare ST, to TPI with local anesthetic, and TPI with NS for LBP conducted in an ED. It will also be the first TPI study to incorporate a patient centered functional outcome and patient follow-up after discharge from an ED. TPI's are a popular treatment modality for LBP among many Emergency Medicine Providers. However, to date, there is limited evidence for or against it. The investigators are hopeful that this study will answer whether or not trigger point injections are benefiting patients and, if so, which type of TPI is most beneficial. Read Less

This clinical trial will determine the added benefit of combining exercise and behavioral health education (versus exercise and aging and health education) to improve physical activity in community-dwelling older adults who have painful knee osteoarthritis (OA). Read Less

This study is being done to answer the following question: Is the combination of the Medtronic pump and the Codman catheter device a safe alternative to the C3000 Codman pump for delivering chemotherapy directly into the liver of patients with metastatic colorectal cancer or cholangiocarcinoma?

The purpose of this study is to assemble a multicenter prospective cohort of patients with enterococcal bloodstream infections (BSIs) to provide data on outcomes of patients with enterococcal BSIs for sample size calculations for future trials, as well as to characterize enterococcal isolates causing BSIs in order to comprehensively dissect the molecular epidemiology of infecting organisms for future studies.

This is a prospective, observational study designed to describe disease progression, symptom change, quality of life, diet and lifestyle habits, and frequency of adverse events among patients with multiple sclerosis (MS) who use complementary and alternative medicine (CAM). In addition to describing the patterns of CAM use, this study will also identify and describe the positive deviants, those individuals with the highest quality of life and least amount of disease activity. Positive deviants will be compared to controls in order to describe medication, diet, and lifestyle patterns associated with a lack of MS disease progression and high quality of life. Read Less

Local injection of 5-fluorouracil into a chalazion (stye) is as effective as local injection of triamcinolone (steroid) and incision and curettage for treatment of chalazia. Read Less
