Acceptability and Engagement of a Smartphone-Delivered Interpretation Bias Intervention in a Sample of Black and Latinx Adults: Open Trial.

Background: Access to evidence-based interventions is urgently required, especially for individuals of minoritized identities who experience unique barriers to mental health care. Digital mental health interventions have the potential to increase accessibility. Previous pilot studies testing HabitWorks, a smartphone app providing an interpretation bias intervention, have found strong engagement and adherence for HabitWorks; however, previous trials' samples consisted of predominantly non-Hispanic, White individuals.

Mescaline: The forgotten psychedelic.

Introduction: Mescaline (3,4,5-trimethoxyphenethylamine) is one of the oldest hallucinogens, with evidence of use dating back 5700 years. Mescaline is a naturally occurring alkaloid found in cacti, mainly in the peyote cactus (Lophophora williamsii) and in the cacti of the Echinopsis genus. Since the prohibition of psychoactive substances in the early 70s, research on mescaline and other classical psychedelics has been limited.

Examination of Outcomes among Sexual Minorities in Treatment for Obsessive-Compulsive and Related Disorders.

The first-line psychological treatment for obsessive-compulsive and related disorders (OCRDs) is exposure and response prevention (ERP). As the first study to examine treatment outcomes for sexual minorities, it is crucial to examine: (1) how treatment-seeking individuals who identify as sexual minorities compare to heterosexual individuals in symptom severity at admission, length of stay in treatment, and (2) whether ERP is equally effective for sexual minorities. The current study explored these questions in an intensive/residential treatment (IRT) program for OCRDs.

Endoscopic ultrasound-guided diagnosis of Helicobacter pylori-associated gastric Burkitt's lymphoma in an adolescent patient: a rare case.

Primary gastric Burkitt's lymphoma (BL) is rare in the pediatric population. Furthermore, the association of Burkitt's lymphoma with Helicobacter pylori is not well defined. We report a case of primary gastric Burkitt's lymphoma associated with Helicobacter pylori diagnosed in a pediatric patient.

Trauma-related cognitions predict treatment response in smokers with PTSD: Evidence from cross-lagged panel analyses.

Objective: Compared to smokers without posttraumatic stress disorders (PTSD), smokers with PTSD smoke more heavily and are less successful in quitting smoking. However, limited research has examined the cognitive pathways underlying this heightened comorbidity. The current study is the first to simultaneously model the cross-sectional and lagged relationships between trauma-related cognitions and cigarette smoking, as well as between trauma-related cognitions and PTSD severity, in smokers with comorbid PTSD receiving treatment.

An Innovative Mobile Game for Screening of Pediatric PTSD: a Study in Primary Care Settings.

Childhood is a developmental period associated with high risk of posttraumatic stress disorder (PTSD). Available validated pencil-and-paper diagnostic tools can be difficult for younger children to engage with given format and length. This study investigated psychometric properties of a briefer, more interactive game version of the Child PTSD Symptom Scale for DSM-5 (CPSS-5).

Human Pharmacokinetic Parameters of Orally Administered Δ-Tetrahydrocannabinol Capsules Are Altered by Fed Versus Fasted Conditions and Sex Differences.

There is variability in the reported Δ-tetrahydrocannabinol (THC) and 11-hydroxy-tetrahydrocannabinol (11-OH-THC) pharmacokinetic (PK) and pharmacodynamic (PD) parameters between studies and there is limited investigation into how the presence of food or sex affect these parameters. In this study, we examined the PK and PD parameters of an encapsulated THC extract and its major active metabolite, 11-OH-THC, under different fed states. The study was a single-dose, randomized, double-blinded, four-way crossover investigation.

Nevus Unius Lateris: A Case Report.

Nevus unius lateris is a rare congenital hamartoma derived from the ectoderm, considered to be a systematized verrucous variant of an epidermal nevus. Due to its extensive unilateral distribution, it is frequently associated with neurological, musculoskeletal, auditory, and visual abnormalities. A case report of a 25-year-old female patient with a diagnosis of nevus unius lateris without associated comorbidities is presented.

Improving Pain Management in Patients with Sickle Cell Disease from Physiological Measures Using Machine Learning Techniques.

Pain management is a crucial part in Sickle Cell Disease treatment. Accurate pain assessment is the first stage in pain management. However, pain is a subjective response and hard to assess via objective approaches.

Effects of Leaflet Design on Transvalvular Gradients of Bioprosthetic Heart Valves.

Bioprosthetic aortic valves (BAVs) are becoming the prostheses of choice in heart valve replacement. The objective of this paper is to assess the effects of leaflet geometry on the mechanics and hemodynamics of BAVs in a fluid structure interaction model. The curvature and angle of leaflets were varied in 10 case studies whereby the following design parameters were altered: a circular arch, a line, and a parabola for the radial curvature, and a circular arch, a spline, and a parabola for the circumferential curvature.

Design of Bioprosthetic Aortic Valves using biaxial test data.

Bioprosthetic Aortic Valves (BAVs) do not have the serious limitations of mechanical aortic valves in terms of thrombosis. However, the lifetime of BAVs is too short, often requiring repeated surgeries. The lifetime of BAVs might be improved by using computer simulations of the structural behavior of the leaflets.

Preparing today's cardiovascular trainees to meet the challenges of tomorrow: team research and interdisciplinary training.

There is a growing focus on interdisciplinary team approaches in science and public health research, including cardiology. This trend is apparent in a large body of team publications and the strong interest from the funding agencies to support interdisciplinary research. Despite this increased emphasis on the importance and roles of teams, schools fail to better prepare their students and trainees with skills that allow them to work in or lead teams.

Quicker yet safe: skeletonization of 1640 internal mammary arteries with harmonic technology in 965 patients.

Objectives: Skeletonization of the internal mammary artery (IMA) facilitates arterial grafting and has been shown to reduce deep sternal infection but is more time-consuming and tedious than pedicle harvest. We wished to determine if use of harmonic technology (HT) facilitates skeletonization of the IMA and is as safe as the conventional technique of skeletonization.

Methods: In a consecutive series of 1057 patients with isolated coronary artery bypass graft (CABG) surgery from 2003 to 2013, adverse events and recorded harvest times were compared between harmonic (965 patients) and non-harmonic patients (86 patients).

Canadian cardiac surgeons' perspectives on biomedical innovation.

Barriers to successful innovation can be identified and potentially addressed by exploring the perspectives of key stakeholders in the innovation process. Cardiac surgeons in Canada were surveyed for personal perspectives on biomedical innovation. Quantitative data was obtained by questionnaire and qualitative data via interviews with selected survey participants.

Cell therapy limits myofibroblast differentiation and structural cardiac remodeling: basic fibroblast growth factor-mediated paracrine mechanism.

Background: Experimental cell therapy attenuates maladaptive cardiac remodeling and improves heart function. Paracrine mechanisms have been proposed. The effect of cell therapy on post infarction cardiac fibroblast and extracellular matrix (ECM) regulation was examined.

Kryptonite bone cement prevents pathologic sternal displacement.

Background: Wire cerclage closure of sternotomy is the standard of care despite evidence of pathologic sternal displacement (> 2 mm) during physiologic distracting forces (coughing). Postoperative functional recovery, respiration, pain, sternal dehiscence, and infection are influenced by early bone stability. This translational research report provides proof-of-concept (part A) and first-in-man clinical data (part B) with use of a triglyceride-based porous adhesive to rapidly enhance the stability of conventional sternal closure.

Resident and bone marrow-derived mesenchymal stem cells in head and neck squamous cell carcinoma.

Head and neck squamous cell carcinoma (HNSCC) is a major healthcare problem worldwide affecting more than half a million patients each year. Despite considerable advances in the treatment of HNSCC, a high rate of recurrences aggravates the clinical situation and disease outcomes have only modestly improved. Recent insights show that cancer is not only a disease of the transformed epithelium but is also influenced and dependent on its stromal environment.

Defining the DNA mismatch repair-dependent apoptotic pathway in primary cells: evidence for p53-independence and involvement of centrosomal caspase 2.

Many studies have shown that DNA mismatch repair (MMR) has a role beyond that of repair in response to several types of DNA damage, including ultraviolet radiation (UV). We have demonstrated previously that the MMR-dependent component of UVB-induced apoptosis is integral to the suppression of UVB-induced tumorigenesis. Here we demonstrate that Msh6-dependent UVB-induced apoptotic pathway is both activated via the mitochondria and p53-independent.

Genipin blues: an alternative non-toxic crosslinker for heart valves?

Background And Aim Of The Study: One approach in tissue-engineering involves the implantation of decellularized, xenogenic scaffolds, with the expectation of repopulation in vivo. However, a major limitation of this method is the propensity to induce a strong immune host response. The study aim was to mitigate this immunogenicity by employing a crosslinking treatment with genipin.

Sustained release and activation of the growth factor basic fibroblast growth factor from loaded scaffolds in heart valve tissue engineering.

Objectives: Loading of biological matrices offers an opportunity to induce specific cell behaviour. We previously reported the use of growth factors to promote cell invasion and proliferation in tissue valve engineering. We investigated biological matrices preloaded with heparin as an ionically attractive template for the binding, activation and sustained release of basic fibroblast growth factor (bFGF).

Differential impact of TGF-beta and EGF on fibroblast differentiation and invasion reciprocally promotes colon cancer cell invasion.

Several studies indicate that cancer-associated fibroblasts play a critical role in cancer cell invasion and metastasis, the hallmarks of malignancy. To better understand the mechanisms underlying such effects, we established a heterotypic model of human fibroblasts (primary colon fibroblasts and immortalized human dermal fibroblasts) in co-culture with human colon cancer cells (HCT-8/E11), using three-dimensional collagen type-I and Matrigel matrices. We report that TGF-beta is the unique and dominant factor to provide pro-invasive signals to HCT-8/E11 colon cancer cells from TGF-beta-treated human fibroblasts in three-dimensional collagen type I and Matrigel matrices.
