NCT02232659
The SynCardia 70cc temporary Total Artificial Heart (TAH-t) is approved by the U.S. Food and Drug Administration (FDA) for use as a bridge to transplant for patients at risk of imminent (about to happen) death from irreversible biventricular heart failure. The purpose of this research study is to evaluate whether the TAH-t can support patients with life-threatening irreversible biventricular heart failure who are not eligible for transplantation. The TAH-t, when used for patients who are not eligible for transplant, is considered to be an investigational (not approved by FDA) use. This use is called destination therapy (DT). Nineteen (19) patients with life-threatening, biventricular failure who are not eligible for cardiac transplant will be enrolled in the Primary Arm of the study and followed for up to six months post-TAH-t implant. Safety will be evaluated by reviewing the adverse events that are experienced by the enrolled subjects and comparing them to previous experience of TAH-t patients who were waiting for a heart transplant. Since approximately 74% of patients with this condition would not be expected to live beyond six months, the benefit of the TAH-t for DT will be confirmed based on survival to six months without experiencing permanent disabling stroke-related deficits. After the six month follow-up visit, patients will continue to be followed under the study for up to five (5) years postTAH-t implant \[every six months for up to two years while supported with the TAH-t implant and then annually for another three years\]. Up to an additional 19 patients may be enrolled in the Secondary Arm of the study to further characterize the use of the TAH-t for DT in a broader patient population. Follow-up would be the same for patients enrolled in both arms of the study.
NCT04788082
Patient-specific, 3D printed models have been utilized in preoperative planning for many years. Among researchers and clinicians, there is a perception that preoperative exposure to 3D printed models, derived from patient images (CT or MRI), aid in procedural planning. 3D printed models for heart surgery have the potential to improve a clinician's preparedness and therefore may reduce surgically-related morbidity and mortality. This randomized clinical trial aims to evaluate whether pre-procedural planning of surgeons exposed to a patient-specific 3D printed heart model will decrease cardiopulmonary bypass time, morbidity, and mortality.

NCT04823637
Context: Thoracic spine is a common area of focus in osteopathic manipulative medicine (OMM) for a variety of conditions. Thoracic spine somatic dysfunction diagnosis is achieved by palpating for asymmetry at the tips of the transverse processes. Previous studies reveal that, instead of following the rule of threes, the transverse processes of a given thoracic vertebra generally align with the spinous process of the vertebra above. Ultrasonography has been widely used as a diagnostic tool to monitor musculoskeletal conditions. Ultrasound has the advantage of absence of radiation, and has shown comparable results to gold standard modalities like MRI in some areas of the spine. In the case of thoracic somatic dysfunction, ultrasound can be used to determine the location of each vertebral transverse process and its relationship with the spinous process. Previous studies have investigated the correlation between osteopathic manipulative medicine and ultrasonography of the cervical, lumbar, and sacral regions. However, no study has yet compared osteopathic structural examination with ultrasonographic examination of the thoracic vertebral region. Objective: To determine whether there is a dependable correlation of osteopathic palpatory findings of the thoracic transverse processes with the measurements of ultrasonography. Methods: Subjects were student volunteers recruited from the Midwestern University - Glendale campus. A non-toxic, non-permanent marker was used to mark bony landmarks on the skin to be used by the osteopathic examiners. Two osteopathic physicians (OMM1, OMM2) separately performed structural exams by palpating T2-T5 transverse processes to determine vertebral rotation. Two trained sonographers (US1, US2) separately scanned and measured the distance from the tip of the spinous process to the adjacent transverse processes of the vertebral segment below. Demographic variables were summarized with mean and standard deviation. Interexaminer reliability was assessed with percent agreement, Cohen's Kappa, and Fleiss' Kappa. Recruitment and protocols were approved by the MWU Institutional Review Board.

NCT02709018
This study is being conducted to determine if losartan, an angiotensin receptor blocker (ARB), is safe and effective in the treatment of posttraumatic stress disorder (PTSD) symptoms. The study is also intended to determine if certain genetic markers are useful in predicting PTSD symptom reduction with losartan. Approximately 160 subjects with chronic PTSD ages 18-65 will participate in this study across five sites. Subjects will be assigned by chance to take either flexibly dosed losartan (up to a maximum dosage of 100 mg) or placebo (which resembles the study drug but has no active ingredients), once a day for 10 weeks. Furthermore, it is hypothesized that CC homozygotes for rs4311 SNP in the ACE gene will have a superior response to losartan on PTSD symptoms compared to T carriers.
NCT00485433
The purpose of this study is to evaluate three dose levels of SKY0402 compared with 105 mg of bupivacaine HCl.
NCT00614744
This study is a randomized, placebo-controlled, clinical trial to evaluate whether induced whole-body hypothermia initiated between 6-24 hours of age and continued for 96 hours in infants ≥ 36 weeks gestational age with hypoxic-ischemic encephalopathy will reduce the incidence of death or disability at 18-22 months of age. The study will enroll 168 infants with signs of hypoxic-ischemic encephalopathy at 16 NICHD Neonatal Research Network sites, and randomly assign them to either receive hypothermia or participate in a non-cooled control group.
NCT02897765
The purpose of this study is to evaluate if the treatment with NEO-PV-01 + adjuvant in combination with nivolumab is safe and useful for patients with certain types of cancer. The study also will investigate if NEO-PV-01 + adjuvant with nivolumab may represent a substantial improvement over other available therapies such as nivolumab alone. All eligible patients will receive NEO-PV-01 + adjuvant and nivolumab while on this trial.
NCT00318591

NCT01757067
Premature ventricular contractions (PVC) are a very common irregular heart beat (arrhythmias) even in patients without heart disease. Frequent PVCs are thought to occur in about 1-4% of the general population. Many patients with PVCs complain about skipping of their heart (palpitations), shortness of breath and feeling tired. In some patients PVCs may also result in weakening of the heart muscle (heart failure), which might be reversible with suppression of the PVCs.
NCT00439296
This is a phase I/II study of an investigational drug called ABT-751, produced by Abbott Laboratories, given in combination with chemotherapy drugs used to treat acute lymphoblastic leukemia (ALL) that has come back (recurred). The phase I portion of this study is being done to find the highest dose of ABT-751 that can be given safely in combination with other chemotherapy drugs. A safe dose is one that does not result in unacceptable side effects. After a safe dose for ABT-751 given with chemotherapy has been found, the study will add additional patients to find out if ABT-751 (given at the maximal safe dose) when given with additional chemotherapy is an effective therapy for the treatment of children with relapsed ALL. It is expected that approximately 15-35 children and young adults will take part in this study.
NCT01963650

NCT00905060
This phase II trial studies the side effects and how well HSPPC-96 (vitespen) and temozolomide work in treating patients with newly diagnosed glioblastoma multiforme. Vaccines made from a person's tumor cells and heat shock protein peptide may help the body to build an effective immune response to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving HSPPC-96 (vitespen) together with temozolomide may kill more tumor cells.
