The social cognitive deficits associated with autism spectrum disorder (ASD) are related to an imbalance in excitatory and inhibitory neurotransmission, specifically a deficit in the inhibitory neurotransmitter GABA. The investigators have used magnetic resonance spectroscopy (MRS) techniques to measure GABA in specific brain regions and have demonstrated that a single dose of gabapentin increases GABA in brain regions associated with social cognition. This study will use a biomarker-driven approach to investigate gabapentin to correct the underlying imbalance of neurotransmitters and improve the core social cognitive deficits in ASD. By using a brain-based biomarker (GABA) that is quantifiable and measurable, the investigators can target this biomarker directly and measure the impact of the treatment. This will help with the future development of targeted therapies for ASD and provide an early marker of response to aid in the selection of individuals more likely to respond to various treatments. The specific aims of this study are to: 1) determine if treatment with gabapentin sustainably increases GABA in the right anterior insula (RAI; an area of the brain involved in social cognition), 2) determine if response of RAI GABA levels to a single dose challenge of gabapentin predicts a sustained response after treatment, and 3) determine if the increase in GABA levels with gabapentin treatment translates into clinically measurable improvement in social cognition. The investigators will conduct an 8-week open-label clinical trial of gabapentin in 40 adolescents (age 13-17 years) with ASD, using MRS before and after treatment to measure GABA in the RAI (the primary outcome for the study). Before the trial, a single dose challenge of gabapentin will be used to evaluate the immediate response of GABA levels in the RAI, to determine if this predicts later response. A secondary outcome will be the clinical effects of gabapentin on social cognition. This study can demonstrate for the first time that neuroimaging biomarkers can be used to guide treatment of social cognition deficits seen in ASD and that the excitatory-inhibitory imbalance in neurotransmitters in ASD can be pharmacologically targeted. This can provide a rational basis for pharmacological treatment of the core social deficits of ASD, providing direct benefit to participants in the study as well as indirect benefit to countless patients in the future.

Our intent is to establish the International Registry to Improve Outcomes in Men with Advanced Prostate Cancer (IRONMAN) as a prospective, international cohort of minimum 5,000 men with advanced cancer, including men with mHSPC and M0/M1 CRPC. The goal is to establish a population-based registry and recruit patients across academic and community practices from Australia, Barbados, Brazil, Canada, Ireland, Jamaica, Kenya, Nigeria, Norway, Spain, South Africa, Sweden, Switzerland, the United Kingdom (UK), and the United States (US). Target accrual number and number of participating sites are subject to change based on accrual, funding, and interest in participation by other international sites. This cohort study will facilitate a better understanding of the variation in care and treatment of advanced prostate cancer across countries and across academia and community based practices. Detailed data will be collected from patients at study enrollment and then during follow-up, for a minimum of five years. Patients will be followed prospectively for overall survival, clinically significant adverse events, comorbidities, changes in cancer treatments, and PROMs. PROMs questionnaires will be collected at enrollment and every three months thereafter. Physician Questionnaires will be collected from all participating sites at patient enrollment, time of first change in treatment and/or one year follow-up, at each subsequent change of treatment, and discontinuation of treatment. As such, this registry will help identify the treatment sequences or combinations that optimize overall survival and PROMs for men with mHSPC and M0/M1 CRPC. By collecting blood at enrollment, time of first change in treatment and/or one year follow-up (plasma, cell free DNA, buffy coat / RNA), this registry will further identify and validate molecular phenotypes of disease that predict response and resistance to specific therapeutics. Additionally, every effort will be made to collect blood specimen at each subsequent change in treatment due to progression of disease. When feasible, existing tumor tissue may be collected for correlation with described blood based studies. All samples will be used for future research. This cohort study will provide the research community with a unique biorepository to identify biomarkers of treatment response and resistance. Read Less

The objectives of this longitudinal study are to assess and measure fusion status (fused or not fused) and rate of bony fusion using NanoBone® Synthetic Bone Graft in patients requiring one to two level lumbar posterolateral fusion procedures with or without commercially available rigid spinal instrumentation. Our hypothesis is that the Nanobone synthetic bone graft will be as effective at creating a fusion in the lumbar spine as compared with a local bone graft. Each subject will serve as their own control during this study, as patients will receive the Nanobone graft on the right side of their spine and the local bone graft on their left side. Read Less

This study involves sample collection to identify biomarkers relating to Autism Spectrum Disorder(ASD) in the saliva of children who are between the ages of 18 months to 6 years and 11 months. Participants will at each timepoint have a non-invasive saliva swab collected and complete a brief demographic and medical history questionnaire as well. Children in the pediatric/provider setting who will receive a referral for an ASD diagnosis because they were determined to have a suspicion of developing ASD will be enrolled in the study. Children will also be enrolled in the specialist evaluation setting where they will receive a DSM-5 diagnosis. A subset of both enrollment cohorts will also be followed up with at a third time point in which their diagnosis will be confirmed, and information about any ongoing treatment will be gathered.

Postoperative pulmonary complications (PPCs) are a major cause of morbidity and mortality in surgical patients. National estimates suggest 1,062,000 PPCs per year, with 46,200 deaths, and 4.8 million additional days of hospitalization. The objective of the study is to develop and implement perioperative strategies to eliminate PPCs in abdominal surgery, the field with the largest absolute number of PPCs. We will conduct a randomized controlled pragmatic trial in 750 studied participants. The effectiveness of an individualized perioperative anesthesia-centered bundle will be compared to the usual anesthetic care in patients receiving open abdominal surgery. At the end of this project, the investigators expect to change clinical practice by establishing a new and clinically feasible anesthesia-centered strategy to reduce perioperative lung morbidity. The research will be conducted across 14 US academic centers, and will be funded by the National Institute of Health. Read Less

This study is a postmarketing requirement jointly carried out by four NDA holders (Bayer AG, Bracco, GE Healthcare and Guerbet) and the CRO IQVIA. The study aims to create detailed images of the organs and tissue of the human body during x-ray, CT-scan or MRI investigations, doctors are using contrast media (a kind of dye) which can be given to patients by injection into a blood vessel or by mouth. In this study researchers want to find out whether so called gadolinium-based contrast agents (GBCAs) have an effect on body movement and mental skills when given to participants multiple times within 5 years. The study plans to enroll about 2076 participants suffering from a condition for which they are likely to have at least annually a MRI or another imaging examinations. Only adults up to 65 years will be considered to join this study. During the study duration of 5 years participants will receive annually a MRI or other imaging tests (such as CT-scan, x-ray) and will visit the study doctor at least 7 times for physical examinations, laboratory investigations and tests on body movement and mental skills.

The purpose of this study is to see if stool transplant performed by colonoscopy is effective at treating recurrent Clostridium difficile (C. diff) infection of the colon. During the procedure a stool sample is taken from a healthy donor (usually family member or close friend) and transplanted directly into the colon of the patient with C. diff infection. The goal of this experimental procedure (called fecal microbiota transplantation) is to replenish the good bacteria in the colon that can help prevent C. diff infection from coming back after treatment.
