Matthew S Lazarus, Rebecca B Forman, Alan L Brook, Todd S Miller
BACKGROUND: Image guidance for spine pain control procedures, including epidural steroid injection, nerve root block, and facet block, can be performed with either computed tomography (CT) or conventional fluoroscopy. CT has the advantage of improved anatomic localization and use of air for contrast; however, there are concerns that CT leads to higher radiation dose and longer procedure time. OBJECTIVE: To evaluate procedure time and radiation dose for multiple types of spine pain control procedures performed under CT guidance...

Abdul-Kareem H Ahmed, Peter F Schnatz, Eli Y Adashi
In 1968, the American Medical Association resolved to accept qualified graduates of osteopathic medical schools into its accredited Graduate Medical Education (GME) programs. An equally momentous decision was arrived at in 2014 when the Accreditation Council for Graduate Medical Education (ACGME), the American Osteopathic Association (AOA), and the American Association of Colleges of Osteopathic Medicine (AACOM) resolved to institute a single unified GME accreditation system by July 1, 2020. As envisioned, the unified accreditation system will all but assure system-wide consistency of purpose and practice in anticipation of the Next Accreditation System (NAS) of the ACGME...

Eric I-Hun Jeng, Nikolaus Gravenstein, Charles T Klodell
BACKGROUND: Endoscopic thoracic sympathectomy (ETS) is indicated for refractory hyperhidrosis. The pulse oximetry-derived perfusion index (PI) quantifies pulsatile blood flow at the oximeter. Thoracic sympathectomy increases blood flow; thus we postulate it will reliably increase PI. We evaluated the ipsilateral finger PI as a predictor of successful sympathectomy during ETS. METHODS: After institutional review board approval and informed consent, 100 adult patients undergoing bilateral ETS were studied...

Background.: Patient engagement efforts often rely on a participatory research approach, which means engaging patients and community members in all aspects of research. As research team members, they require familiarity with the principles of human subject protection, privacy, and institutional review boards (IRB). However, the time required for individual IRB training may be a barrier to engaging community members in participatory research. As more community members participated in research, the State Networks of Colorado Practices and Partners (SNOCAP) was faced with finding a balance between including community members as part of the research team and the significant time commitment and institutional requirements for human subjects research oversight...

BACKGROUND: Intimate partner violence (IPV) is a critical public health and human rights concern globally, including for refugee women in low-resource settings. Little is known about effective interventions for this population. IPV and psychological distress have a bi-directional relationship, indicating the potential benefit of a structured psychological component as part of efforts to reduce IPV for women currently in violent relationships. METHODS: This protocol describes a cluster randomized controlled trial aimed at evaluating an 8-session integrated psychological and advocacy intervention (Nguvu) with female adult survivors of past-year IPV displaying moderate to severe psychological distress...
