The investigators will accomplish our research aims by collecting cutaneous microbiome samples from 50 persons that have undergone the Osseointegration (OI) surgery at eight timepoints, prospectively. The investigators will also collect control samples to correct for turnovers in species compositions that may naturally occur and to compare the residual limb microbiome to the sound contralateral limb. The investigators will sequence the bacterial community using universal bacterial primers. Using these sequences, The investigators will borrow from ecological theory and calculate the alpha and beta diversity. The alpha diversity will determine the species and abundance of each species that are present, while the beata diversity will allow us to compare how species assemblages and frequencies change between time points. Then, the investigators will take a phylogenetic modeling approach to determine if particular species assemblages correlate with rates of wound healing. The investigators will construct phylogenies from the sequences at the different time points and "paint" the rate of wound healing along the phylogeny (e.g., improved, stagnated, worsened). Using Akaike and Bayesian information criterion, the investigators can determine which phylogenetic model best explains the patterns the investigators see across patients. Lastly, the investigators will quantify soft tissue stability and health and correlate this with the homeostasis of the microbial community. Specifically, the investigators will determine if redundant soft tissue leads to altered microbial communities that can impact the rate of wound healing. Finally, the investigators will further stratify these data to compare microbial communities between the sexes, upper versus lower limbs, and proximal versus distal amputations. This work will allow us to better treat infections after OI surgery and can shed light on wound healing process so that the investigators can better treat limb loss patients and the military community as a whole.

Art therapy is used across the Military Health System for treatment of posttraumatic symptoms, but there is limited research on how art therapy is able to restore emotional expression and regulation in service members. This research hopes to learn about the effects of art therapy on emotional expression and regulation in service members as well as the neurological systems at work. If a participant chooses to be in this study, he or she will attend ten sessions over a period of twelve weeks. The first session will be an interview and self-assessment questionnaires to collect information on a variety of symptoms, experiences, and personality traits, and an MRI scan. During the MRI scan, participants will be asked to perform a task where they will be shown a series of neutral and negative images. The middle eight sessions will be one-hour art therapy sessions with a certified art therapist. The last session will consist of the same self-assessment questionnaires and another MRI scan.

This study is one of the three projects of an NIH Rare Disease Clinical Research Consortium. A "consortium" is a group of centres sharing information and resources to perform research. The consortium research focuses on brain blood vessel malformations in three different rare diseases. The focus of this specific study is on Hemorrhagic Telangiectasia (HHT). HHT is a condition characterized by blood vessel malformations, called telangiectasia and arteriovenous malformations (AVMs), occurring in the brain, nose, lungs, stomach, bowels and liver. Brain AVMs (BAVMs) in HHT are difficult to study because they are rare, affecting approximately 10% of people with HHT. While other types of BAVMs have been studied in depth, studies in the HHT population have been very small. Here, we propose the first large-scale collaboration by joining with 12 HHT Centers of Excellence in North America to perform a large study of risk factors for bleeding from BAVMs, called intracranial hemorrhage (ICH) in HHT patients. The current standard of clinical practice across North America, is to screen all HHT patients for BAVMs with magnetic resonance imaging (MRI). If BAVMs are detected, patients are referred to a multidisciplinary neurovascular team for consideration for treatment. Treatment decisions are made on a case by case basis, balancing risks of complications from the BAVM with risks of therapy, but are limited by the few studies available in HHT. We hope that the knowledge we obtain about the risk factors for intracranial bleeding in these patients from this larger study will help us to improve the care of HHT patients. We plan to study risk factors for rupture of BAVMs, including primarily genetics and imaging characteristics of the BAVMs. Knowledge about risk factors will help in the care and management of HHT patients. This will be achieved through the collection of health information to construct a HHT database, blood sampling and banking (through the National Institute of Neurological Disorders and Stroke \[NINDS\]), and through genetic analysis at the University of California San Francisco.

This is a prospective natural history study of CIPN in approximately 200 participants receiving taxanes (paclitaxel, docetaxel) for breast cancer, bortezomib for multiple myeloma, oxaliplatin-based regimens for colorectal cancer, or vincristine for lymphoma.. Demographic data, medical history, electronic PROs, ClinROs blood biomarkers including NF-L, PGx DNA analyses and Bedside-QST will be assessed at Baseline. The Observation Period will initiate with the first dose of chemotherapy and conclude with the last dose of chemotherapy. During the Observation Period, participants will be evaluated for the development of CIPN using PROs and ClinROs. Blood biomarkers and Bedside-QST will be measured at various timepoints corresponding with treatment regimen schedules throughout the observation period. The Post Chemotherapy Follow-up Period will begin with the first visit after the last dose of chemotherapy and conclude 6 months after the last dose of chemotherapy. During the Post Chemotherapy Follow-up Period, participants will be evaluated for CIPN using PROs and ClinROs. Blood biomarkers and Bedside-QST will also be measured at the beginning and at the end of the Post-Chemotherapy Follow-up Period. PROs will be assessed electronically on a monthly basis. Read Less

Investigators will enroll 320 patients who will undergo non-cardiac surgery, receive supplemental oxygen via face mask, and will be on a continuous pulse oximetry monitor in the Post Anesthesia Care Unit (PACU). The enrollment criteria were adapted from a previous study that showed SpO2 values seriously underestimated the severity of post-operative hypoxemia in patients with and without specific risk factors for hypoxemia. Research personnel will screen and ensure that each subject meets the enrollment criteria, and the informed consent is properly executed. Upon arrival to the PACU, each subject will be fitted with oxygen mask containing the Linshom sensor, which will be connected to a Linshom monitor for data collection. A side stream capnography line will be connected to the same face mask and the capnography data will be collected on the Zoe Medical 740 SELECT™ monitor. Additionally, two pulse oximeters will be applied to the same hand (non- NIBP arm), one of which will be connected to a hospital monitor (SoC) and the other to a Zoe Medical 740 SELECT™ monitor. The Linshom and 740 SELECT™ monitors will collect data once every second. Research personnel will then initiate the Linshom CPRM baseline mode and begin recording any clinical intervention (e.g., medications, oxygen delivery change, and stimulation upon detection of changes in patient's condition) that is performed by the PACU staff, paying close attention to, and recording of time at which those interventions occurred. Data collection will be performed throughout the subject's entire PACU stay. The CPRM data collection will be performed passively while the patient is monitored via SoC and will not interfere with clinical interventions that may take place during the data collection. Clinical staff in the PACU will be blinded to the Linshom CPRM data as well as pulse oximetry (non-SOC monitor) and capnography data collected. Read Less

The objective is to identify modifiable clinical factors and neurobiological pathways that lead to the development of chronic pain in patients with early rheumatoid arthritis. Participants will undergo quantitative sensory testing, a type of testing that involves assessing response to well-defined, quantifiable painful stimuli, at 0, 3, and 12 months. A subset of participants will also undergo magnetic resonance imaging at 0 and 12 months to assess neuroimaging markers that have previously been shown to be involved in chronic pain. Read Less

Enroll-HD is a longitudinal, observational, multinational study that integrates two former Huntington's disease (HD) registries-REGISTRY in Europe, and COHORT in North America and Australasia-while also expanding to include sites in Latin America. More than 30,000 participants have now enrolled into the study. With annual assessments and no end date, Enroll-HD has built a large and rich database of longitudinal clinical data and biospecimens that form the basis for studies developing tools and biomarkers for progression and prognosis, identifying clinically-relevant phenotypic characteristics, and establishing clearly defined endpoints for interventional studies. Periodic cuts of the database are now available to any interested researcher to use in their research - visit www.enroll-hd.org/for-researchers/access-data/ to learn more. Read Less
