Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. Many individuals find themselves being passed from physician to physician, undergoing countless and often repetitive tests in the hopes of finding answers and insight about what the future may hold. This long and arduous journey to find a diagnosis does not end for many patients- the Office of Rare Diseases Research (ORDR) notes that 6% of individuals seeking their assistance have an undiagnosed disorder. In 2008, the National Institutes of Health (NIH) Undiagnosed Diseases Program (UDP) was established with the goal of providing care and answers for these individuals with mysterious conditions who have long eluded diagnosis. The NIH UDP is a joint venture of the NIH ORDR, the National Human Genome Research Institute Intramural Research Program (NHGRI-IRP), and the NIH Clinical Research Center (CRC) (1-3). The goals of the NIH UDP are to: (1) provide answers for patients with undiagnosed diseases; (2) generate new knowledge about disease mechanisms; (3) assess the application of new approaches to phenotyping and the use of genomic technologies; and (4) identify potential therapeutic targets, if possible. To date, the UDP has evaluated 3300 medical records and admitted 750 individuals with rare and undiagnosed conditions to the NIH Clinical Center. The NIH UDP has identified more than 70 rare disease diagnoses and several new conditions. The success of the NIH UDP prompted the NIH Common Fund to support the establishment of a network of medical research centers, the Undiagnosed Diseases Network (UDN), for fiscal years 2013-2020. The clinical sites will perform extensive phenotyping, genetic analyses, and functional studies of potential disease-causing variants. The testing performed on patients involves medically indicated studies intended to help reach a diagnosis, as well as research investigations that include a skin biopsy, blood draws, and DNA analysis. In addition, the UDN will further the goals of the UDP by permitting the sharing of personally identifiable phenotypic and genotypic information within the network. By sharing participant information and encouraging collaboration, the UDN hopes to improve the understanding of rare conditions and advance the diagnostic process and care for individuals with undiagnosed diseases....

This phase II clinical trial tests how well the cytomegalovirus-modified vaccinica Ankara (CMV-MVA) Triplex vaccine given to human leukocyte antigens (HLA) matched related stem cell donors works to prevent cytomegalovirus (CMV) infection in patients undergoing hematopoietic stem cell transplant. The CMV-MVA Triplex vaccine works by causing an immune response in the donors body to the CMV virus, creating immunity to it. The donor then passes that immunity on to the patient upon receiving the stem cell transplant. Giving the CMV-MVA triplex vaccine to donors may help prevent CMV infection of patients undergoing stem cell transplantation.

The objective of the study is to investigate the treatment of marginal ulcers with Low Thermal plasma in an endoscopic setting. By a treatment of the ulcerated areas with argon plasma with low power settings (~ 1 W) we hypothesize that the size of the ulcers will shrink, and the healing is accelerated compared to standard of care alone. Patients will benefit from this minimally invasive approach compared to a much more invasive surgical approach that comes with higher risks and hospital stay length time. From a societal and scientific perspective, this study aims to extend the well-documented clinical benefits of plasma technology - from external wound healing to internal ulcer treatment - within an endoscopic framework. The success of this study could pave the way for broader applications of LTP in the treatment of other endoscopically accessible conditions such as peptic ulcers, duodenal ulcers and esophageal ulcers. This advancement has the potential not only to improve patient outcomes through less invasive methods, but also to position LTP as a cornerstone in the future of gastroenterological wound management strategies.

The objective of the study is to investigate the efficacy and safety of an argon plasma-based therapy - HEAPE - in treating H. pylori infections during endoscopic procedures. By filling the stomach with sodium chloride solution that is treated with APC (PAL), the Investigators hypothesize a significant reduction in H. pylori. The use of PAL instead of direct application of APC allows for a broader and more homogeneous application throughout the stomach and a faster procedure time, as the fluid bypasses the thermal effects typically associated with higher electrical power settings and focuses on the bactericidal action of PAL. It is a procedure that does not involve thermal ablation of the stomach lining. Thus, side effects should be expected to be as low as possible. Two different PAL generation modalities will be compared in this study: 1. HEAPE direct: This modality is the direct generation of PAL in the stomach. The stomach is filled with sodium chloride solution which is then treated with APC. With HEAPE direct a potential decrease of reactive species is avoided, as the treatment happens directly at the intended location in the H. pylori infected stomach. 2. Pre-HEAPE: This modality features the treatment of sodium chloride with APC outside of the patient in a sterile container. After the APC treatment, the generated PAL is administered into the stomach with a syringe through the working channel of the endoscope. Pre-HEAPE allows an easier handling of the APC probe as the treatment of the sodium chloride solution can be done without an endoscope. To evaluate the immediate effect of this novel treatment approach the metabolic activity of H. pylori will be assessed using a urea breath test (UBT) before and after treatment. A reduction in H. pylori levels can be detected by a reduction in urease activity in the breath test. After the HEAPE procedure, patients are treated with antibiotics (best practice) as they would be under normal circumstances. Four weeks after treatment, another UBT is performed to determine if H. pylori has been eradicated or if additional antibiotic treatment is indicated. This two-arm, randomized, pilot, single-center, prospective clinical study is designed to evaluate the safety, tolerability and proof of concept that PAL has the ability to eradicate or reduce the bacterial load of H. pylori in humans.

The e-OPRA Implant System, is a further development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) Implant System. The e-OPRA Implant system is an implant system for direct skeletal anchorage of amputation prostheses. The added feature in the e-OPRA Implant system, is a bidirectional interface into the human body that allows permanent and reliable communication using implanted electrodes. These electrodes will provide long-term stable bioelectric signals for an improved control of the prosthetic limb. The Magnetic Bead Tracking System, which will be implanted and used in combination with the e-OPRA Implant system, is an investigational device that consists of pairs of magnetic beads, and a set of magnetic field sensors that measure and track the length of muscles and the speed at which they move in real-time. When the beads are implanted in muscle in the residual limb of an amputee, the muscle length signal is communicated to an investigational, robotic ankle-foot prosthesis. The purpose of the study is to evaluate the feasibility of a transtibial amputee with the e-OPRA Implant System and Magnetic Bead Tracking System exhibiting full neural control over a neuro-mechanical prosthetic system. A maximum of seven subjects will be enrolled. Each subject will undergo one or more surgeries where the e-OPRA Implant System and Magnetic Bead Tracking System will be implanted. The subjects will participate in follow-up sessions the last of which occurs approximately 24 months after the surgery. This is a prospective, non-randomized, uncontrolled study.
