NCT07027150
The goal of this clinical trial is to evaluate the accuracy of the Perin Health Patch, a chest-worn pulse oximeter, in healthy adult volunteers by comparing its measurements to arterial blood gas analysis during controlled hypoxemia. This study will help determine whether the device meets the performance requirements of ISO 80601-2-61 and FDA 510(k) for SpO₂ measurement accuracy. The main questions it aims to answer is whether the Perin Health Patch meet the required accuracy performance (Arms ≤ 3.5%) across the full range of 70-100% SaO₂ as defined by ISO 80601-2-61. Participants will be healthy adults aged 18 to 50 years old, representing a diverse range of skin tones (including ≥15% with Fitzpatrick V or VI). Inclusion criteria require general good health and no chronic medical conditions. Exclusion criteria include obesity, cardiopulmonary conditions, hemoglobinopathies, pregnancy, and other safety considerations. Participants will: * Undergo screening and informed consent, including skin tone assessment using colorimetry and spectrophotometry. * Be instrumented with the Perin Health Patch and reference pulse oximeters on randomized fingers. * Undergo placement of an arterial catheter by a trained physician. * Be asked to breathe through a mouthpiece while inspired oxygen concentration is gradually reduced under physician control to generate multiple plateaus of hypoxemia (70-100% SaO₂). * Provide up to 30 arterial blood samples at steady-state hypoxemia levels to determine functional SaO₂ via co-oximetry. * Be continuously monitored for SpO₂, heart rate, ECG, respiratory rate, and blood pressure during the study. * Return to normoxia, and have the arterial line removed with hemostasis confirmed before discharge. This protocol, based on UCSF's standard hypoxia lab procedures, has been used in over 3000 subjects and is designed to meet or exceed requirements of ISO 80601-2-61, ISO 14155, and FDA 510(k) standards.
NCT06850857
The goal of this observational study is to validate a novel patient-reported outcome measure (PROM) for patients suffering maxillofacial trauma: The Integrated Modular Patient-Reported Outcome Assessment for Craniomaxillofacial Trauma (IMPACT). The primary question is: Are the IMPACT modules valid and reliable measures to study quality-of-life (QOL) in patients with maxillofacial trauma? Patients presenting for routine clinic follow-up for maxillofacial trauma will be invited to complete the IMPACT in addition to the 15 Dimension (15D) QOL survey as a control.
NCT03079414
Sudden cardiac death (SCD) remains a major cause of mortality within developed nations despite aggressive efforts to reduce its societal burden. Despite extensive clinical and genetic investigations, a subgroup of cardiac arrests remain unexplained, highlighting the potential contribution of additional cardiac conditions that may not be identified with contemporary diagnostic algorithms. The EPS ARREST study aims to evaluate the role of invasive electrophysiology study within this patient population.
NCT05958654
The purpose of this study is to evaluate whether the use of the Detection of Elder Mistreatment Through Emergency Care Technicians-Revised for Primary Care (DETECT-RPC) screening tool increases the average reporting of elder mistreatment (EM) by homebased primary care (HBPC) clinicians.
NCT04250415
Investigators from eight tertiary care, level 1 pediatric trauma centers have developed a protocol for the establishment of a formal, prospective multi-center adolescent clavicle registry, with designs for standardized radiographic assessment and the prospective collection of validated outcome measures and complications data, for all patients, ages 10-18, treated for clavicle shaft fractures, operatively and non-operatively. Eventually, the investigators would like to do comparative analysis for the operative and non-operative treatment arms, with additional sub-stratified analyses performed within these treatment arms by age and activity level. Among the primary goals of research projects stemming from the first arm of this registry, FACTS A, is to explore the hypothesis that non-operative treatment is associated with lower costs, greater safety, and equivalent or superior outcomes, compared with operative treatment, despite a national trend towards increasing surgical treatment. The second arm of the registry, FACTS B, will continue to investigate the same hypotheses, excluding cost outcomes, in patients only with completely displaced midshaft clavicle fractures.
NCT03442114
The goal of the study is to understand how best to help parents of young children with sickle cell disease and their clinicians have a shared discussion about hydroxyurea (one that takes into account medical evidence and parent values and preferences). The study will compare two methods to help clinicians facilitate this-a clinician pocket guide and a clinician hydroxyurea shared decision making toolkit-in a group of parents of children ages 0-5 with sickle cell disease. The investigators hope that both methods lead to parents reaching a high-quality, well-informed decision. In addition, the team hopes to demonstrate that parents who experience a shared decision will have lower anxiety and decisional uncertainty. The researchers also expect these parents to be more likely to choose hydroxyurea and that their children will have less pain, fewer hospitalizations, better developmental outcomes, and higher quality of life. The project team hopes to show that the toolkit method is easy for clinicians to use and gives parents the support needed to make an informed decision.
NCT06112834
This Phase 2, open-label, uncontrolled study designed to evaluate safety, tolerability, and immunogenicity of a single dose of rBV A/B in healthy participants previously immunized with pentavalent botulinum toxoid (or pentavalent botulinum toxoid and rBV A/B) for occupational protection will be conducted to collect source plasma for potential use in the production of BabyBIG and to evaluate safety and immunogenicity of the vaccine in these participants over a 12-week period, with a follow-up safety assessment at 6 months.

NCT06001541
The majority of Veterans will suffer from at least one chronic illness, often at great emotional and personal cost. Self-management is critical to improving physical and emotional outcomes, and many chronically ill Veterans receive self-management assistance from an informal caregiver, and both Veterans and informal caregivers experience individual and interpersonal stress as they navigate this journey. Yet, current clinical practices are not designed to effectively support the needs of both Veterans and their informal caregiver. Furthermore, self-management practices often require in-person visits, limiting access for Veterans and informal caregivers who live in rural areas, those with a physical disability, or those with financial challenges. This project tests a web-based, self-guided, behavioral intervention that targets the stress coping needs of Veterans with chronic illness and their informal caregivers. Results from this study could provide an important solution to the problem of poor self-management, which complicates the lives and prognosis of many Veterans.
NCT05611918
The investigators propose to perform serial detailed cognitive, motor, behavioral, and blood collection follow-up using longitudinal structured telephone interviews of an anticipated 350 ICH survivors enrolled in Minimally Invasive Surgery Plus Alteplase for Intracerebral Hemorrhage Evacuation (MISTIE) III and ENRICH trials to identify specific cognitive and motor impairment and to perform RNA sequencing to evaluate for evidence of chronic inflammation. The investigators' expected sample size in 2022 accounts for mortality attrition of 10%/year.
NCT05269355
This study will compare the efficacy and safety of unesbulin plus dacarbazine versus placebo plus dacarbazine in participants with unresectable or metastatic, relapsed or refractory LMS who have received at least 1 prior line of systemic therapy.
NCT05296447
This is a prospective, observational study designed to evaluate the long-term safety and efficacy of RGX-314. Eligible participants are those who were previously enrolled in a clinical study of DR without center involved-diabetic macular edema (CI-DME) in which they received SCS administration of RGX-314. Enrollment of each participant in the current study should occur after the participant has completed either the end of study or early discontinuation visit in the previous (parent) clinical study. Participants will be followed for a total of 5 years post-RGX-314 administration (inclusive of the parent study). As such, the total study duration for each participant may vary depending on when they enroll in the current study following RGX-314 administration in the parent study.
NCT05797896
An observational study to investigate the natural history and evaluate biomarkers of participants with geographic atrophy secondary to age-related macular degeneration
NCT04533451
This trial studies the side effects of pembrolizumab with or without chemotherapy in treating patients with stage IV non-small cell lung cancer that has come back (recurrent) and has spread to other places in the body (advanced). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as pemetrexed and carboplatin, 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 pembrolizumab with or without chemotherapy may shrink the tumor in older patients with non-small cell lung cancer.
