Filter by:Functional connectivity is defined as a correlation in neural activity between distinct regions of the brain. Several recent studies have demonstrated areas of low-frequency functional connectivity inherent to brain tissue at rest. These oscillations can be measured using functional magnetic resonance imaging (fMRI) and appear to be synchronized between related areas of the brain. To date, no investigators have examined the effects of low-dose anesthesia on functional connectivity. This study will image the human brain under conditions of rest, and low-dose anesthetic induced sedation. Quality of the acquired signals will be evaluated and functional networks in the brain will be examined. Of interest is whether administration of a low-dose anesthetic disrupts functional connectivity in the brain, and whether a disruption of functional connectivity is responsible for the reported analgesic and antidepressant effects of a anesthetic. Participation in the study includes four visits: an in-person interview, an initial fMRI scan, the anesthesia infusion, and a second fMRI scan. There is an optional follow-up fMRI scan one week post infusion.
This randomized phase II trial studies how well cisplatin with or without WEE1 inhibitor MK-1775 works in treating patients with head and neck cancer that has come back or has spread to other parts of the body. Drugs used in chemotherapy, such as cisplatin, may prevent tumor cells from multiplying by damaging their deoxyribonucleic acid (DNA), which in turn stops the tumor from growing. WEE1 inhibitor MK-1775 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether cisplatin is more effective with or without WEE1 inhibitor MK-1775 in treating patients with head and neck cancer.
The purpose of this study is to compare the use of Prevena™ Incision Management System (IMS) versus standard wound care for the incision in subjects undergoing a sternal midline incision (sternotomy). The subjects targetted for the study are at high risk for surgical complications (like infections) around the environment of the incision. The study is conducted in The Netherlands, Germany and Austria.
To compare the long-term (one-year) bronchodilator efficacy and safety of COMBIVENT hydrofluoroalkane (HFA) Inhalation Aerosol to COMBIVENT chlorofluorocarbon (CFC) Inhalation Aerosol and Placebo formulations of each in patients with COPD. In addition, steady state pharmacokinetics over one dosing interval following four weeks of therapy will be characterized.
This study aims to compare the efficacy and safety of three alternative methods of analgesia in patients undergoing complex liver resection surgery: 1) thoracic epidural analgesia (TEA), 2) continuous paravertebral block (PVB) with patient-controlled analgesia (PCA) and 3) patient-controlled analgesia (PCA) alone. Regional anesthesia techniques such as TEA and PVB may improve recovery and decrease postoperative pain scores in addition to other benefits such earlier return of bowel function and shortened length of hospital stay, although some practitioners have voiced concerns about the safety and efficacy of these techniques in patients after liver resection who may develop postoperative coagulation abnormalities. The investigators plan to enroll a total of 150 patients (adults >/= 18 years of age who meet study criteria) scheduled for complex liver resection surgery in this study, who will then be randomized into 50 patients per arm of the study (3 total arms). Postoperative pain scores will be collected in PACU and throughout the patient's hospital stay as well as routine blood tests including complete blood count, coagulation labs (PT/INR, aPTT) and serum creatinine to measure renal function. The study team will also collect additional data prospectively on all patients enrolled in the study; these parameters will include age, sex, type of operation performed, length of operation, volume of intraoperative blood loss, volume of intraoperative fluid administration including blood products, daily postoperative intravenous fluid administration, length of time to first feeding, day of epidural catheter removal, length of hospital stay and incidence of major postoperative complications (surgical, respiratory, cardiac, renal, etc.). Once primary and secondary data points are obtained, the data will undergo rigorous statistical analysis using the appropriate statistical techniques to determine the outcomes. The investigators propose that epidural and/or paravertebral analgesia may improve recovery times and decrease hospital length of stay, which would be beneficial for the patient as well as decrease hospital costs. In addition, if better postoperative pain management scores can be achieved with epidural or paravertebral analgesia, and no significant prolonged postoperative coagulopathy is associated with patients undergoing major hepatic resection surgical procedures, these regional analgesia strategies can be considered a safe option for pain management in this patient population.
The purpose of this signal seeking study was to determine whether treatment with ceritinib demonstrated sufficient efficacy in select pathway-activated solid tumors and/or hematologic malignancies to warrant further study.
Background: The forces involved in a patella dislocation event can cause significant collateral damage involving the articular cartilage of the patella femoral joint. As a result, prevention of recurrent patella dislocation and the associated disability and morbidity has generated significant interest in the orthopedic community. Historically, nonoperative treatment for first time patella dislocation has been problematic due to high redislocation rates. Nonoperative protocols generally involve bracing and/or immobilization, followed by physical therapy (1). Surgical approaches to recurrent patella dislocation, both soft tissue and boney realignment operations, have also had mixed results, including low success rates, associated complications, and variable rates of return to functional activity (2,3,4). This study is intended to compare the outcomes of a relatively low-risk Medial Patellofemoral Ligament (MPFL) direct repair procedure to conservative treatment. Methods/Design: This study is designed as a two arm randomized prospective trial. Approximately fifty subjects will be randomly assigned to either a surgical or non-operative arm by means of a computer randomized allocation program. All subjects will have X-Ray Images and Magnetic Resonance Imaging (MRI) to determine the site of the MPFL damage, and to determine if any excluding conditions exist. Subjects randomized to the surgical group will have repair of the MPFL. Routine aftercare will consist of physical therapy in a clinic that has agreed to follow our protocol. Subjects randomized to the nonoperative group will receive 2 weeks of patellar immobilization, followed by patellar stabilization bracing with physical therapy for approximately 12 weeks. Physical therapy will progress through five phases with the goal of gait normalization, full range of motion and return to sport. Both arms will be given outcome questionnaires and physical activity assessments before treatment, and at one, three, six, twelve, and twenty four month intervals. Discussion: This prospective randomized trial will investigate the results of direct repair of the medial patellofemoral ligament and conservative treatment by applying subjective outcome measures (Kujala scores), and exam findings to determine MPFL functional restoration or redislocation. Subjects will be examined in the clinic setting at 10 days, one month, and six months post trauma. Any reported recurrent dislocation or subluxation event will be documented during recovery. All subjects will receive merchant x-ray views at 3 months with manual lateral translation of the patella.
This postmarket surveillance study is being conducted to evaluate the TRANSITION Stabilization System as an adjunct to fusion in the treatment of acute or chronic instabilities or deformities of the thoracic, lumbar and sacral spine. The study will involve up to 360 subjects at no more than 20 sites, to be treated with the TRANSITION Stabilization System. The data from this postmarket surveillance study will be provided to FDA in accordance with the 522 order.
