Damage of woven composite under tensile and shear stress using infrared thermography and micrographic cuts

Infrared thermography was used to study damage developing in woven fabrics. Two different experiments were performed, a ±45° tensile test and a rail shear test. These two different types of tests show different damage scenarios, even if the shear stress/strain curves are similar. The ±45° tension test shows matrix hardening and matrix cracking whereas the rail shear test shows only matrix hardening. The infrared thermography was used to perform an energy balance, which enabled the visualization of the portion of dissipated energy caused by matrix cracking. The results showed that when the resin is subjected to pure shear, a larger amount of energy is stored by the material, whereas when the resin is subjected to hydrostatic pressure, the main part of mechanical energy is dissipated as heat

The prognostic value of initial EDI scores in anorexia nervosa patients: a prospective follow-up study of 5–10 years

SummaryAimTo study in a prospective manner the long-term prognostic value of the initially recorded Eating Disorder Inventory (EDI) scores in anorexia nervosa (AN) patients.MethodsThe 5–10-year outcome of 26 consecutive malnourished AN patients was prospectively recorded according to the initial EDI score. We selected only patients with full 6-month assessments for more than 5 years (mean 8.5 years). Eating behavior, quality of life, autonomy and insight capacity were prospectively assessed by the Morgan-Russell scale and a semi-structured interview. At the end of follow-up, 13 patients recovered and the 13 others had a poor outcome.ResultsIn monovariate analyses, high initial EDI total score (P &lt; .0007) and high initial scores for perfectionism (P &lt; .001), ineffectiveness (P &lt; .002), interpersonal distrust (P &lt; .004), interoceptive awareness (P &lt; .03) and drive for thinness (P &lt; .05) were significantly associated with a poor prognosis 5–10 years afterward. In a multivariate analysis, only high initial scores for perfectionism (F = 8.43; P = 0.008) and interpersonal distrust (F = 7.46; P = 0.012) were significantly associated with illness severity.DiscussionHigh EDI total score and subscales for perfectionism and interpersonal distrust could predict a long-term severe outcome in AN.</jats:sec

El valor pronόstico de los valores iniciales del EDI en pacientes de anorexia nerviosa: un estudio de seguimiento prospectivo de 5-10 años

ResumenPropósito:Estudiar de una manera prospectiva el valor pronóstico a largo plazo de las pun-tuaciones del Inventario de Trastornos de la Conducta Alimentaria (EDI) registradas inicialmente en pacientes con anorexia nerviosa (AN).Métodos:Se registró prospectivamente durante 5-10 aiios la evolución de 26 pacientes desnutridos consecutivos con AN según la puntuación inicial del EDI. Seleccionamos sólo a las pacientes con evaluaciones completas cada 6 meses durante más de 5 años (media 8,5 años). Se evaluó prospectivamente la conducta alimentaria, la calidad de vida, la autonomía y la capacidad de insight por la Escala de Morgan-Russell y una entrevista semiestructurada. Al final del seguimiento, 13 pacientes se habían recuperado y las otras 13 habían tenido una evolución mala.Resultados:En los análisis univariados, la puntuación total inicial alta del EDI (P &lt;0,0007) y las puntua-ciones iniciales elevadas para perfeccionismo (P &lt;0,001), ineficacia (P &lt;0,002), desconfianza interpersonal (P &lt;0,004), conocimiento interoceptivo (P &lt;0,03) y deseo de delgadez (P &lt;0,05) estaban signifi-cativamente asociadas con un mal pronóstico 5-10 años después. En un análisis multivariado, s61o las pun-tuaciones iniciales altas para perfeccionismo (F = 8,43; P &lt;0,08) y desconfianza interpersonal (F = 7,46; P &lt;0,012) estaban significativamente asociadas con la gravedad de la enfermedad.Discusión:Una puntuación total alta del EDI y las subescalas para perfeccionismo y desconfianza interpersonal podían pre-decir una evolución grave a largo plazo en la AN.</jats:sec

Overcoming Perfectionism: Protocol of a Randomized Controlled Trial of an Internet-Based Guided Self-Help Cognitive Behavioral Therapy Intervention

Background: Perfectionism is elevated across, and increases risk for, a range of psychological disorders as well as having a direct negative effect on day-to-day function. A growing body of evidence shows that cognitive behavioral therapy (CBT) reduces perfectionism and psychological disorders, with medium to large effect sizes. Given the increased desire for Web-based interventions to facilitate access to evidence-based therapy, Internet-based CBT self-help interventions for perfectionism have been designed. Existing Web-based interventions have not included personalized guidance which has been shown to improve outcome rates. Objective: To assess the efficacy of an Internet-based guided self-help CBT intervention for perfectionism at reducing symptoms of perfectionism and psychological disorders posttreatment and at 6-month follow-up. Methods: A randomized controlled trial method is employed, comparing the treatment arm (Internet-based guided self-help CBT) with a waiting list control group. Outcomes are examined at 3 time points, T1 (baseline), T2 (postintervention at 12 weeks), T3 (follow-up at 24 weeks). Participants will be recruited through universities, online platforms, and social media and if eligible will be randomized using an automatic randomizer. Results: Data will be analyzed to estimate the between group (intervention, control) effect on perfectionism, depression, and anxiety. Completer and intent-to-treat analyses will be conducted. Additional analysis will be conducted to investigate whether the number of modules completed is associated with change. Data collection should be finalized by December 2016, with submission of results for publication expected in mid-year 2017. Results will be reported in line with recommendations in the Consolidated Standards of Reporting Trials Statement for Randomized Controlled Trials of Electronic and Mobile Health Applications and Online TeleHealth (CONSORT-EHEALTH). Conclusions: Findings will contribute to the literature on treatment of perfectionism, the effect of treating perfectionism on depression and anxiety, and the efficacy of Internet-based guided self-help interventions.
