Healthy Recovery After Trauma Study
Christal L Badour Stress Disorders, Post-Traumatic Shame Guilt Sexual Assault and Rape
Mental contamination-an internal experience of dirtiness evoked in the absence of physical contact with an external source-has been linked to the development and maintenance of posttraumatic stress disorder (PTSD) following exposure to sexual abuse or assault (Adams et al., 2014; Badour et al., 2011 expand

Mental contamination-an internal experience of dirtiness evoked in the absence of physical contact with an external source-has been linked to the development and maintenance of posttraumatic stress disorder (PTSD) following exposure to sexual abuse or assault (Adams et al., 2014; Badour et al., 2013; Brake et al., 2017). Mental contamination has been associated with greater PTSD severity (Rachman et al., 2015) and higher elevations in specific PTSD symptom clusters (particularly those of intrusive reexperiencing, negative cognitions/mood, and arousal/reactivity; Brake et al., 2019; Fergus & Bardeen, 2016). Additionally, trauma-related mental contamination has been linked to a number of negative posttraumatic emotions such as shame, guilt, disgust, and anger (Fairbrother & Rachman, 2004; Radomsky & Elliott, 2009) Despite clear and consistent links between mental contamination and problematic posttraumatic outcomes following sexual trauma, there is a dearth of research investigating how existing or promising new interventions for PTSD impact mental contamination. Cognitive Processing Therapy (CPT) is an efficacious and effective 12-session manualized cognitive-behavioral intervention for PTSD that is considered a gold-standard empirically-supported treatment for PTSD that is recommended by the American Psychological Association (APA, 2017). In addition to PTSD symptom improvement, CPT has also demonstrated benefit for improving feelings of shame and guilt, which are often seen among individuals with trauma-related mental contamination (Nishith et al., 2005; Resick et al., 2002, 2008). Cognitive reappraisal, a primary technique employed in CPT, involves challenging one's view of an emotionally-eliciting situation to alter its emotional impact (Gross & John, 2003). However, some investigators have suggested that cognitive reappraisal may be less effective in targeting moral emotions such as shame, guilt, and self-disgust that are based on an individual's standards and virtues (Finlay, 2015). Self-compassion (SC; i.e., self-directed care and kindness; forgiveness; and feelings of common humanity; Neff, 2003) has been proposed as an alternative method for addressing trauma-related shame and preliminary evidence suggests a 6-session self-compassion intervention may have benefit for reducing both PTSD symptoms and trauma-related shame (Au et al., 2017). Given the centrality of shame, guilt, and self-disgust to the experience of mental contamination, and the fact that mental contamination often arises in response to experiences involving moral violation or betrayal (Millar et al., 2016; Rachman, 2010), a SC intervention for PTSD may also offer promise as a standalone or adjunctive intervention for reducing trauma-related mental contamination. A test of these interventions for their impact on reducing trauma-related mental contamination is needed. The current study will use Single Case Experimental Design to isolate and evaluate the effects of CPT and SC in reducing both PTSD symptoms and trauma-related mental contamination among individuals with PTSD resulting from sexual trauma. Aims: 1) explore whether participants demonstrate reductions in mental contamination and PTSD symptoms in response to 12-sessions of CPT or 6-sessions of a SC intervention; 2) evaluate whether presentation of either treatment first yields differences in symptom reduction for PTSD and/or mental contamination symptoms; 3) evaluate whether the addition of the alternative module will enhance reductions in PTSD symptoms and mental contamination; 4) evaluate if such reductions are maintained during follow-up. Visual inspection analysis and statistical methods will be used to draw conclusions regarding the effects of the interventions on PTSD symptoms and mental contamination.

This clinical trial will help us learn more about how to best care for babies with Neonatal Opioid Withdrawal Syndrome, also called NOWS. Babies with NOWS often have tremors, a hard time sleeping, excessive crying, and trouble feeding. Some babies that have NOWS need medicine. Doctors have two ways of providing medicine that are widely used today: 1. Scheduled opioid taper approach. The baby gets medicine at regular times. As symptoms get better, the amount of medicine the baby gets decreases until the baby no longer needs medicine. This is called a medicine taper. 2. Symptom-based approach. The baby will only get medicine when they show signs of NOWS, instead of at regular times. If the baby is showing no signs of NOWS, no medicine will be given. We are doing the OPTimize NOW study to figure out the best way to give medicine to babies with NOWS.

This study is researching an experimental drug called odronextamab, referred to as study drug. The study is focused on participants with previously untreated follicular lymphoma. Follicular lymphoma is a type of non-Hodgkin lymphoma or NHL. Participants with follicular lymphoma that has come back after treatment (called "relapsed") or did not respond to treatment (called "refractory") are eligible to take part only in Part 1A of the study. This study is made up of 3 parts: Part 1A (non-randomized), Part 1B and Part 2 (randomized - controlled). The aim of Part 1A and Part 1B of the study is to see how safe and tolerable the study drug in combination with chemotherapy is and to determine the dose and schedule of the study drug to be combined with chemotherapy to be used in Part 2 of the study. The aim of Part 2 of the study is to assess how effective the combination of the study drug with chemotherapy is in comparison with the combination of rituximab and chemotherapy (the current standard-of-care for NHL). Standard-of-care means the usual medication expected and used when receiving treatment for a condition. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in the blood at different times - Whether the body makes antibodies against the study drug (which could make the study drug less effective or could lead to side effects) - The impact from the study drug on quality-of-life and ability to complete routine daily activities

The primary aim of this study is to evaluate the reported pain intensity following placement of Orthodontic separators on healthy volunteers aged 18-49 in relation to their recorded physical activity level. Hypothesis 1: The investigators hypothesize that participants with higher daily step counts and physical activity levels will report significantly less pain intensity from orthodontic separators than their less active peers following separator placement. Null hypothesis is that participants with higher daily step counts will report the same pain intensity from orthodontic separators than their less active peers following separator placement The secondary aim is to describe the course of pain, at 24 hr intervals, over the next seven days following separator placement. Hypothesis 2: The investigators hypothesize that more physically active participants will report ratings of zero pain intensity faster (sooner) than their less active peers throughout the one week study. Secondary null hypothesis is that more physically active participants will report ratings of zero pain intensity at the same rate as their less active peers throughout the one week study.

The overarching hypotheses of this protocol are that (1) persistent brain glutamate changes induced by chronic opioid use will exacerbate use of cocaine during opioid physical dependence and withdrawal and (2) n-acetylcysteine (NAC) will ameliorate glutamatergic dysregulation, and thus will reduce both opioid and cocaine demand. These hypotheses will be tested with two specific aims. Specific Aim 1. Determine the reinforcing effects of cocaine in individuals with comorbid opioid and cocaine use disorder with physiological dependence on opioids during NAC maintenance. All subjects will be maintained on oral hydromorphone. They will also be randomly assigned to receive placebo or oral NAC (2.4 g/day), stratified by sex. After dose stabilization, experimental sessions will be conducted in which subjects complete hypothetical cocaine purchase tasks during opioid maintenance and opioid withdrawal. The hypotheses are: 1) cocaine purchasing will be greater during opioid withdrawal and 2) NAC maintenance will attenuate cocaine purchasing across opioid maintenance and withdrawal periods. Specific Aim 2. Evaluate glutamate functionality during periods of opioid maintenance and withdrawal in individuals with comorbid opioid and cocaine use disorder and physiological dependence on opioids during NAC maintenance. Subjects will undergo magnetic resonance spectroscopy to evaluate brain glutamate changes as a function of opioid maintenance/withdrawal state and NAC maintenance. The hypotheses are: 1) glutamate levels will be elevated during opioid withdrawal and 2) NAC maintenance will ameliorate elevated glutamate levels.

Biomarkers for Vascular Contributions to Cognitive Impairment and Dementia (MarkVCID) is an NIH-funded consortium dedicated to finding biomarkers involved in age-related thinking and memory problems. Alzheimer's disease and other dementias leave signatures on brain scans or in the blood called biomarkers. The MarkVCID study will measure a panel of candidate biomarkers in 1800 participants and watch them closely to see what they tell us about changes in brain function and risk of memory loss. Age-related problems in thinking and memory represent some of the greatest risks to public health in the US and globally. Diseases that affect small blood vessels in the brain have been shown to be major contributors to these changes. However, research and patient care can be held back by limited biomarkers that identify who should be treated. The MarkVCID Consortium includes 17 US medical centers, a Coordinating Center, an External Advisory Committee, and NIH leadership. Data and biospecimens collected as part of this research study will be stored in a research database and biorepositories, so that researchers can use this information to study brain function.

Anterior cruciate ligament (ACL) rupture is one of the most common musculoskeletal injuries in young individuals, particularly those that are active in sports. Up to 30% of individuals under the age of 20 years suffer a re-injury to the reconstructed ACL. Revision ACLR has been associated with degeneration of the articular cartilage and increased rates of meniscal tears, increasing the risk of post-traumatic osteoarthritis (PTOA), additional surgical procedures, reduced physical function and quality of life. As such, strategies to reduce ACLR failure, particularly in young active individuals, are critical to improving short and long-term outcomes after ACL rupture. There is ongoing debate about the optimal graft choice and reconstructive technique. Three autograft options are commonly used, including the bone-patellar-tendon-bone (BPTB), quadriceps tendon (QT) and hamstring tendon (HT). Additionally, a lateral extra-articular tenodesis (LET) may provide greater stability to the ACLR; however, its effect on failure rate is unclear and surgery-induced lateral compartment OA is a concern. To definitively inform the choice of autograft and the need for a LET, this multicenter, international randomized clinical trial will randomly assign 1236 young, active patients at high risk of re-injury to undergo ACLR using BPTB or QT autograft with our without LET.
