The purpose of this study is to determine the effects of a brain stimulation technique known as transcranial direct current stimulation, or tDCS, on the benefits of Prolonged Exposure therapy, or PE, which is an effective treatment for posttraumatic stress disorder, or PTSD. tDCS has been demonstrated to be safe and effective for influencing brain activity by passing a weak electrical current through the scalp. In this study, tDCS is provided in addition to PE treatment, through the National Crime Victim's Research and Treatment Center at MUSC, or the PTSD Clinical Team Clinic within the Ralph H. Johnson VA Medical Center.
This research is taking place at the Ralph H. Johnson VAMC and surrounding Community-Based Outpatient Clinics (CBOCs). This study is examining the effectiveness of PE-PC in VHA primary care mental health integration (PCMHI) clinics. We will randomize Veterans presenting in VA PC with chronic PTSD who meet minimal inclusion/exclusion criteria to receive PE-PC (four, 30-minute weekly sessions) or PCMHI treatment as usual.
The primary objective of this study is to develop a blood-based gene expression signature, known as the ONC-LN-04 Lung Test, to be used in the detection of lung cancer in patients who underwent radiologic screening for lung cancer and had lung nodules detected. We intend to enroll volunteers who are being evaluated by a Ralph H. Johnson VAMC pulmonologist as part of their standard medical care. Participants will be patients who have either (a) radiologic evidence of lung nodules, or (b) a confirmed diagnosis of non-small cell lung cancer (NSCLC) and has not undergone surgical excision, chemotherapy or radiation therapy for this malignancy. A single blood sample will be obtained from willing participants, then stored and analyzed for measurement of gene expression and development of the ONC-LN-04 test. Active participation in this study will be over once a blood sample is obtained; however, we may need access to participants' medical records post-enrollment and sample collection in order to monitor medical outcomes. Review of participants' medical records will occur until up to approximately 5,000 subjects have been enrolled and have provided clinical information and a blood sample.
The aim of this study is to gather information about veterans at the Ralph H. Johnson Veterans Medical Center (RHJ-VAMC) who've experienced a stroke and are interested in participating in rehabilitation research.
VA principal investigators at the Center for Rehabilitation Research in Neurologic Conditions (CRRNC) conduct stroke rehabilitation research for individuals. CRRNC include laboratories that investigate and assess upper extremity motor function, neuro-stimulation, communication and swallowing, locomotor energetics, locomotor and rehabilitation, and motor performance functions.
Participants will be asked to come to the CRRNC located at the Medical University of South Carolina (77 President Street, Charleston, South Carolina) and fill out a simple screening form with study personnel. Participants may be contacted in the future for qualifying studies.
