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.

The goal of this clinical trial is to determine the feasibility of studying massage therapy in patients with gynecologic cancers while receiving infusion treatments. The central hypothesis is that it is feasible to implement a massage intervention study in an infusion center at an academic hospital, and measure pain and anxiety in patients with gynecological cancer. The main questions it aims to answer are: Can investigators evaluate feasibility to conduct a study from a design standpoint? Can investigators assess the use of randomization, blinding of assessors, potential to control the study with an attention group, and recruitment/retention processes? Can investigators successfully collect outcome measures of pain and anxiety, pre/post intervention? Researchers will investigate degree of resources needed, such as massage therapists, assessors, and timing of delivery intervention. Assess positive/negative effects on target population determining massage modality and anatomical location. Researchers will compare massage therapy to an attention control group, to see if massage therapy works to treat pain and anxiety in patients with cancer. Establish variability in outcome measures. Participants will: Be randomized and receive either massage therapy or attention control over the course of three consecutive infusion therapy treatments. Each infusion therapy treatment occurs every 2-4 weeks.

This study looks at whether walking with a therapy dog helps adult and pediatric trauma patients move more during their hospital stay. Early movement after an injury or surgery can prevent problems such as blood clots, pressure sores, and muscle loss, but pain and anxiety often make it hard for patients to get out of bed. Each patient in this study takes part in two walking sessions-one with a certified therapy dog and one without a dog. The order is randomized, so some patients walk with the dog first and others walk without the dog first. Before and after each walk, patients fill out short surveys about their pain, anxiety, and motivation to move. The research team measures how far and how long each patient walks in both sessions. The goal of this project is to see if therapy dog visits can safely and effectively improve mobility, reduce pain and anxiety, and make walking more enjoyable for trauma patients. Findings from this study may help hospitals design better rehabilitation programs that use animal-assisted therapy to support physical and emotional recovery.

The PRCT evaluates infection outcomes as well as fracture and antibiotic-related complications to include the emergence of resistant bacteria associated with two different antibiotic strategies in the treatment of Gustilo type IIIB tibia and hindfoot fractures (calcaneus and talus) and selected IIIA fractures of the tibia and trauma-related transtibial amputations that are performed in the "zone-of-injury". This study will be conducted in established METRC level 1 trauma centers. The patients will be randomized as close to admission as possible to either 1) Standard of Care (SOC) prophylactic open fracture protocol, including the use of topical antibiotic as per the usual practice of the surgeon or 2) experimental protocol (SEXTANT). The SEXTANT protocol includes application of wound bioburden-targeted topical Vancomycin powder and Tobramycin powder antibiotic treatment at the time of final wound closure/coverage combined with 72 hours of systemic antibiotic coverage targeted to both gram-positive and gram-negative pathogens. The study will compare the results of the current SOC prophylactic coverage to the strategic wound bioburden treatment (SEXTANT) protocol. Up until the time of definitive wound closure/coverage, all patients will be treated per the usual regimen of the surgeon / center and in accordance with current Trauma Quality Improvement Program (TQIP) and Surgical Quality Improvement Program (SQIP) recommendations for the care of open fractures.14,15,17 It includes the administration of systemic antibiotics as close to the time of injury as possible. In the definitive wound closure/coverage procedure post-operative period, participants in the intervention arm will receive 72 hours of systemic antibiotic therapy targeted at the modern wound bioburden, and patients in the usual care arm will receive post-operative care per the usual practice of their surgeon. All other activities related to follow-up and related treatments will proceed per the usual practice of the surgeon.

Peritoneal carcinomatosis from advanced gastro-intestinal malignancy has historically been associated with poor overall survival (≤ 12 months) with few treatment options. Cytoreductive surgery (CRS), which involves removal of all macroscopic tumor nodules, combined with direct administration of heated intra-peritoneal (IP) chemotherapy (HIPEC) to the affected peritoneal surfaces, has been shown to be an effective treatment option that extends overall survival among certain cases of peritoneal carcinomatosis. IP chemotherapy allows delivery of a high dose of cytostatic drug directly onto the peritoneal surfaces at risk for microscopic residual disease while systemic exposure remains limited. Additionally, hyperthermia is known to enhance the cytotoxicity of several agents (including Mitomycin C) and improves the depth of peritoneal penetration. This trial will be a randomized phase 2 comparison of flat dose versus weight-based dose Mitomycin C. The hypothesis of this study is that HIPEC weight-based dosing may result in similarly effective peritoneal Mitomycin C concentrations with less systemic absorption and potential systemic toxicity, compared with the HIPEC flat dosing approach in patients undergoing CRS/HIPEC.
