Posttraumatic stress disorder (PTSD) is frequently accompanied by difficulty concentrating, poor memory, and inability to keep up with tasks, which negatively impacts a person's ability to function at work and in relationships. Currently available treatments do not fully relieve all symptoms. A published research report showed positive evidence that the stimulant medication methylphenidate was beneficial in treating these problems. This study will evaluate the ability of methylphenidate to treat PTSD and associated neurocognitive complaints in Veterans. An innovative feature is the study's N-of-1 design. In this design, every participant will move back and forth every 4-5 weeks between treatment with methylphenidate and treatment with placebo, in random order and under double-blind conditions, over a 20-week period. The investigators will compare the aggregated change in PTSD and neurocognitive symptoms between periods of treatment with methylphenidate versus placebo. Results will help clinicians to better choose the best treatment for Veterans living with PTSD. Read Less

Type 1 diabetes (T1D) results from destruction of insulin-producing beta cells in the pancreas by the body's own immune system (autoimmunity). It is not fully understood what causes this type of diabetes and why there is variation in age of onset and severity between people who develop the disease. The aim of this work is to study very unusual people who develop T1D extremely young, as babies under 2 years of age (EET1D). The investigators think that, for the condition to have developed that early, they must have an unusual or extreme form of autoimmunity. Studying people with EET1D will enable us to look at exactly what goes wrong with the immune system because they have one of the most extreme forms of the disease. Much may be learned about the disease from a small number of rare individuals. The investigators aim to confirm that they have autoimmune type 1 diabetes and then try to understand how they have developed diabetes so young by studying their immune system genes, the function of their immune system, and environmental factors (such as maternal genetics) that may play a role in their development of the disease. People with diabetes diagnosed under 12 months are very rare, live all over the world. and are usually referred to Exeter for genetic testing. Individuals will be contacted via their clinician to ask for more information about their diabetes and their family history. Samples will be collected to study whether they still make any of their own insulin and whether they make specific antibodies against their beta cells in the pancreas. Separately, their immune system will be studied in depth using immune cells isolated from a blood sample. These cells will undergo cutting edge techniques by Dr Tim Tree at King's College London, by Professor Bart Roep at Leiden University Medical Center, Netherlands, and Dr Cate Speake, Benaroya Research Institute, Seattle (USA). Some of these tests have never been used in people of young ages around the world, so an aim of this project will be to develop methods that can be used to study people even if they live far away. Additional funding extends the study for a further 3 years (Phase 2) to include recruitment of infants without diabetes, aged 0-6 years, as controls to enable assessment of how the abnormalities found in autoimmune and non-autoimmune diabetes compare to normal early life development of the immune system.

The study is a quasi-experimental investigation of a sub-acute stabilization center (SASC) for people who have had or are at risk for having an opioid overdose and have an encounter with Seattle Fire Department emergency medical services (EMS) in Seattle, WA. Those transported to the SASC are the intervention participants and two comparison groups will be utilized: eligible Seattle EMS patients who opt not to go to the SASC and King County residents, outside of Seattle, who meet the same eligibility criteria. A comparative interrupted time series analysis is planned to study the main effectiveness outcomes. Seattle Fire EMS will assess, refer, and arrange transport for participants to the SASC. The SASC will offer an array of services including post-overdose monitoring, utilization of buprenorphine and methadone for the treatment opioid use disorder and opioid withdrawal, linkage to ongoing care for OUD, and provision of harm reduction services and supplies. The length of stay in the SASC will be limited to less than 24 hours. A continuous process improvement (CPI) approach will monitor and refine the intervention. Characterization of the interventions will be based upon analysis of service utilization patterns over time along with interviews and surveys with stakeholders. Read Less

The participants are being asked to take part in this clinical trial, a type of research study, because the participants are scheduled to receive or have recently received a hematopoietic cell transplant (HCT) or a solid organ transplant (SOT). Primary Objective To determine if pre-transplant screening for respiratory viral load predicts RVI within 1- year post-transplant among survivors. Secondary Objectives: * To develop and validate a classifier based on pre-transplant immunological profile predictive of developing an acute respiratory viral infection (aRVI), with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors. * To develop and validate a classifier based on Day +100 post-transplant immunological profiles predictive of developing an acute respiratory viral infection (aRVI),with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors .

This is a multicenter pharmacokinetic (PK) subtrial to investigate the PK profile of KVD900 (sebetralstat) in adolescent patients 12 to 17 years of age with Hereditary Angioedema (HAE) type I or II. Read Less

Prospective, single-arm, multi-center study to evaluate safety and effectiveness of the Autus Size-Adjustable Valve in pediatric patients aged 18 months to 16 years requiring surgical pulmonary valve replacement. The Autus Valve may be expanded pre-implant to match the subject's body size. Subjects will be evaluated prior to the Autus Valve implant procedure, immediately post-implant, at hospital discharge, 30 days, 6 months, and annually through 10 years. The Autus Valve may be expanded post-implant via transcatheter balloon dilation to accommodate growth of the subject. In subjects who undergo a post-implant valve expansion, follow-up will continue for a minimum of 1 year after the post-implant valve expansion procedure. Read Less

This is a phase 2a, multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NST-6179 in subjects with intestinal failure-associated liver disease (IFALD) receiving parenteral nutrition (PN). The study will be conducted in 2 sequential parts. Up to 36 subjects diagnosed with IFALD will be enrolled in the study, of which up to 18 subjects will be enrolled in each of the 2 parts and randomized (2:1) to receive NST-6179 (N=12/part) or matched placebo (N=6/part). Subjects in Part A will receive once daily (QD) oral administration of 800 mg (32 mL solution) NST-6179 or placebo for 4 weeks. The NST-6179 dose for Part B is planned to be 1200 mg QD for 12 weeks. Actual dose, however, will be determined during the safety review meeting. Read Less

Up to 25% of intensive care unit (ICU) survivors experience cognitive impairment comparable in severity to mild Alzheimer's disease and related dementias after hospital discharge. Older ICU survivors (ages 60 and older) are at highest risk for delirium and subsequent cognitive impairment, which contribute to higher risk for cognitive decline related to Alzheimer's disease and related dementias. Sleep and activity are essential for recovery from critical illness, yet ICU survivors experience both sleep deficiency and profound inactivity. About 75-80% of ICU patients experience circadian dysrhythmia, which contributes to cognitive decline and increases likelihood of developing Alzheimer's disease and related dementias. The scientific premises of the proposed study are: 1) a combined sleep promotion and cognitive training intervention will have synergistic effects to mitigate the risk of cognitive impairment and development of Alzheimer's disease and related dementias in older ICU survivors; and 2) chronotherapeutic timing of interventions (i.e., adjusting timing of interventions according to circadian rhythm) may improve intervention efficacy.
