    This study was undertaken to determine how effective Eye Movement Desensitization and Reprocessing (EMDR) therapy is in helping clients to lessen or end their cycle of SUDs and behavioral addictions in the long term. Secondly, this study aimed to determine whether or not EMDR therapy increases a client\u27s likelihood of relapse, and whether or not relapse affects the outcome of treatment. Furthermore, this study looked at whether or not clients need to have abstained from their addictive substance for an extended period of time in order for EMDR therapy to be successful in their addictions treatment. The final question that this study intended to answer was whether or not there is a correlation between proposed key components of EMDR treatment and more positive treatment outcomes for people with addictions. Data was collected with a questionnaire designed on Survey Monkey. EMDR therapists registered with The EMDR International Association (EMDRIA) were emailed a link to the survey and asked to respond to the survey themselves (if they met the criteria for participation) and to pass the survey onto current or former clients and people they know who have received EMDR therapy. The survey was also passed on directly to people in my professional network of therapists. The major findings of the research were that EMDR therapy correlates with a significant reduction in research participants\u27 felt degree of addiction to both substances and addictive behaviors. Moreover, these results were maintained over time. Cravings to engage in the said behavioral addiction or SUD most frequently decreased after EMDR therapy sessions. Relapse to alcohol or drug use that research subjects attributed to an EMDR session was rare. In addition, the data revealed that having abstained for periods of time prior to engaging in EMDR therapy does not correlate with more positive treatment outcome

    Autologous bone grafting is the most effective treatment for long-bone nonunions, but it poses considerable risks to donors, necessitating the development of alternative therapeutics. Poly(ethylene glycol) (PEG) microencapsulation and BMP2 transgene delivery are being developed together to induce rapid bone formation. However, methods to make these treatments available for clinical applications are presently lacking. In this study we used mesenchymal stem cells (MSCs) due to their ease of harvest, replication potential, and immunomodulatory capabilities. MSCs were from sheep and pig due to their appeal as large animal models for bone nonunion. We demonstrated that cryopreservation of these microencapsulated MSCs did not affect their cell viability, adenoviral BMP2 production, or ability to initiate bone formation. Additionally, microspheres showed no appreciable damage from cryopreservation when examined with light and electron microscopy. These results validate the use of cryopreservation in preserving the viability and functionality of PEG-encapsulated BMP2-transduced MSCs

    Behavior therapy for pediatric trichotillomania: Exploring the effects of age on treatment outcome

    <p>Abstract</p> <p>Background</p> <p>A randomized controlled trial examining the efficacy of behavior therapy for pediatric trichotillomania was recently completed with 24 participants ranging in age from 7 - 17. The broad age range raised a question about whether young children, older children, and adolescents would respond similarly to intervention. In particular, it is unclear whether the younger children have the cognitive capacity to understand concepts like "urges" and whether they are able to introspect enough to be able to benefit from awareness training, which is a key aspect of behavior therapy for trichotillomania.</p> <p>Methods</p> <p>Participants were randomly assigned to receive either behavior therapy (N = 12) or minimal attention control (N = 12), which was included to control for repeated assessments and the passage of time. Primary outcome measures were the independent evaluator-rated NIMH-Trichotillomania Severity Scale, a semi-structured interview often used in trichotillomania treatment trials, and a post-treatment clinical global impression improvement rating (CGI-I).</p> <p>Results</p> <p>The correlation between age and change in symptom severity for all patients treated in the trial was small and not statistically significant. A 2 (group: behavioral therapy, minimal attention control) × 2 (time: week 0, 8) × 2 (children < 9 yrs., children > 10) ANOVA with independent evaluator-rated symptom severity scores as the continuous dependent variable also detected no main effects for age or for any interactions involving age. In light of the small sample size, the mean symptom severity scores at weeks 0 and 8 for younger and older patients randomized to behavioral therapy were also plotted. Visual inspection of these data indicated that although the groups appeared to have started at similar levels of severity for children ≤ 9 vs. children ≥ 10; the week 8 data show that the three younger children did at least as well as if not slightly better than the nine older children and adolescents.</p> <p>Conclusions</p> <p>Behavior therapy for pediatric trichotillomania appears to be efficacious even in young children. The developmental and clinical implications of these findings will be discussed.</p> <p>Trial Registration</p> <p>Clinicaltrials.gov NCT00043563.</p

    Observation and control of shock waves in individual nanoplasmas

    In a novel experiment that images the momentum distribution of individual, isolated 100-nm-scale plasmas, we make the first experimental observation of shock waves in nanoplasmas. We demonstrate that the introduction of a heating pulse prior to the main laser pulse increases the intensity of the shock wave, producing a strong burst of quasi-monochromatic ions with an energy spread of less than 15%. Numerical hydrodynamic calculations confirm the appearance of accelerating shock waves, and provide a mechanism for the generation and control of these shock waves. This observation of distinct shock waves in dense plasmas enables the control, study, and exploitation of nanoscale shock phenomena with tabletop-scale lasers.Comment: 8 pages of manuscript, 9 pages of supplemental information, total 17 page

    A surgical team simulation to improve teamwork and communication across two continents: ViSIOT™ proof-of-concept study

    Get PDF
    Background: Team communication in operating rooms is problematic worldwide, and can negatively impact patient safety. Although initiatives such as the World Health Organization’s Surgical Safety Checklist have been introduced to improve communication, patient safety continues to be compromised globally, warranting the development of new interventions. Video-based social science methods have contributed to the study of communication in UK ORs through actual observations of surgical teams in practice. Drawing on this, the authors have developed a surgical team simulation-training model (ViSIOT™). A proof-of-concept study was conducted in the UK and USA to assess if the ViSIOT™ simulation-training has applicability and acceptability beyond the UK. Methods: ViSIOT™ training was conducted at two simulation centers in the UK and USA over a 10-month period. All surgical team participants completed a questionnaire (that assessed design, education, satisfaction and self-confidence in relation to the training). Descriptive and inferential statistics were performed for the quantitative data and thematic analysis was conducted for the qualitative data. Results: There was strong agreement from all participants in terms of their perception of the course across all sub-sections measured. Nine themes from the qualitative data were identified. The two countries shared most themes, however, some emerged that were unique to each country. Conclusions: Practical developments in the course design, technology and recruitment were identified. Evidence of the course applicability in the USA provides further affirmation of the universal need for team communication training within ORs. Further studies are required to assess its effectiveness in improving communication in OR practice

    OBJECTIVE: Parkinson disease (PD) is defined by the accumulation of misfolded α-synuclein (α-syn) in Lewy bodies and Lewy neurites. It affects multiple cortical and subcortical neuronal populations. The majority of people with PD develop dementia, which is associated with Lewy bodies in neocortex and referred to as Lewy body dementia (LBD). Other neuropathologic changes, including amyloid β (Aβ) and tau accumulation, occur in some LBD cases. We sought to quantify α-syn, Aβ, and tau accumulation in neocortical, limbic, and basal ganglia regions. METHODS: We isolated insoluble protein from fresh frozen postmortem brain tissue samples for eight brains regions from 15 LBD, seven Alzheimer disease (AD), and six control cases. We measured insoluble α-syn, Aβ, and tau with recently developed sandwich ELISAs. RESULTS: We detected a wide range of insoluble α-syn accumulation in LBD cases. The majority had substantial α-syn accumulation in most regions, and dementia severity correlated with neocortical α-syn. However, three cases had low neocortical levels that were indistinguishable from controls. Eight LBD cases had substantial Aβ accumulation, although the mean Aβ level in LBD was lower than in AD. The presence of Aβ was associated with greater α-syn accumulation. Tau accumulation accompanied Aβ in only one LBD case. INTERPRETATION: LBD is associated with insoluble α-syn accumulation in neocortical regions, but the relatively low neocortical levels in some cases suggest that other changes contribute to impaired function, such as loss of neocortical innervation from subcortical regions. The correlation between Aβ and α-syn accumulation suggests a pathophysiologic relationship between these two processes

    Isotopic insights into microbial sulfur cycling in oil reservoirs

    Microbial sulfate reduction in oil reservoirs (biosouring) is often associated with secondary oil production where seawater containing high sulfate concentrations (~28 mM) is injected into a reservoir to maintain pressure and displace oil. The sulfide generated from biosouring can cause corrosion of infrastructure, health exposure risks, and higher production costs. Isotope monitoring is a promising approach for understanding microbial sulfur cycling in reservoirs, enabling early detection of biosouring, and understanding the impact of souring. Microbial sulfate reduction is known to result in large shifts in the sulfur and oxygen isotope compositions of the residual sulfate, which can be distinguished from other processes that may be occurring in oil reservoirs, such as precipitation of sulfate and sulfide minerals. Key to the success of this method is using the appropriate isotopic fractionation factors for the conditions and processes being monitored. For a set of batch incubation experiments using a mixed microbial culture with crude oil as the electron donor, we measured a sulfur fractionation factor for sulfate reduction of −30‰. We have incorporated this result into a simplified 1D reservoir reactive transport model to highlight how isotopes can help discriminate between biotic and abiotic processes affecting sulfate and sulfide concentrations. Modeling results suggest that monitoring sulfate isotopes can provide an early indication of souring for reservoirs with reactive iron minerals that can remove the produced sulfide, especially when sulfate reduction occurs in the mixing zone between formation waters (FW) containing elevated concentrations of volatile fatty acids (VFAs) and injection water (IW) containing elevated sulfate. In addition, we examine the role of reservoir thermal, geochemical, hydrological, operational and microbiological conditions in determining microbial souring dynamics and hence the anticipated isotopic signatures
