A mixed treatment comparison meta-analysis of metaphylaxis treatments for bovine respiratory disease in beef cattle. Journal of Animal Science, 95(2), 626-635. doi:10.2527/jas2016.1062The objective of this project was to evaluate the effects of antimicrobials approved for parenteral metaphylactic use in feeder and stocker calves on morbidity and mortality for bovine respiratory disease with the use of a mixed treatment comparison meta-analysis. An initial literature review was conducted in April 2016 through Pubmed, Agricola, and CAB (Commonwealth Agricultural Bureau) for randomized controlled trials for metaphylaxis antimicrobial administered parentally to incoming feedlot or stocker calves within 48 h of arrival. The final list of publications included 29 studies, with a total of 37 trials. There were 8 different metaphylactic antimicrobials. Final event outcomes were categorized into bovine respiratory disease (BRD) morbidity cumulative incidence d 1 to <= 60 of the feeding period, BRD morbidity cumulative incidence d 1 to closeout of the feeding period, BRD mortality cumulative incidence d 1 to closeout of the feeding period, and BRD retreatment cumulative incidence morbidity d 1 to closeout of the feeding period. Network meta-analysis combined direct and indirect evidence for all the event outcomes to determine mean odds ratio (OR) with 95% credibility intervals (CrIs) for all metaphylactic antimicrobial comparisons. The "upper tier" treatment arms for morbidity d 1 to <= 60 included tulathromycin, gamithromycin, and tilmicosin. For BRD mortality cumulative incidence d 1 to closeout and BRD retreatment morbidity d 1 to closeout, classifying the treatment arms into tiers was not possible due to overlapping 95% CrIs. The results of this project accurately identified differences between metaphylactic antimicrobials, and metaphylactic antimicrobial options appear to offer different outcomes on BRD morbidity and mortality odds in feedlot cattle

The acceptance and use of the e-Health instrument 'The personal health check' in four Dutch municipalities:Lessons learned

This pilot study assessed the acceptance and use of the e-Health instrument “the Personal Health Check” (PHC) among clients and professionals in primary care settings. By filling in the online PHC instrument, participants were provided insights into their health and lifestyle. When results revealed an increased health risk, participants were advised to undertake additional lab tests measuring blood pressure and haemaglobin levels. Based on the online questionnaire and optional lab tests, participants then received a report that included individually-tailored feedback from the e-Health application about personal health risks and suggestions for health interventions. The PHC was implemented in 2016 in four Dutch municipalities that determined which neighbourhood(s) the PHC targeted and how participants were invited. The Unified Theory of Acceptance and Use of Technology was used as a theoretical framework to address our research questions. Methods used to assess acceptance were: PHC instrument data, data from additional questionnaires completed by PHC participants, focus groups with PHC participants and professionals in primary care, and telephone interviews with non-responders to the invitation to participate in the online PHC. Of the 21,735 invited, 12% participated. Our results showed that participants and professionals in this pilot were predominantly positive about the PHC. Participants reported that they made an effort to apply the PHC lifestyle advice they received. Almost all had the knowledge and resources needed to use the PHC online instrument. Invitations from general practitioners almost doubled participation relative to invitations from the sponsoring municipalities. The overall low response rate, however, suggests that the PHC is unsuitable as a foundation on which to develop local public health policy

Social Cognition in Individuals at Ultra-High Risk for Psychosis:A Meta-Analysis

Treatment in the ultra-high risk stage for a psychotic episode is critical to the course of symptoms. Markers for the development of psychosis have been studied, to optimize the detection of people at risk of psychosis. One possible marker for the transition to psychosis is social cognition. To estimate effect sizes for social cognition based on a quantitative integration of the published evidence, we conducted a meta-analysis of social cognitive performance in people at ultra high risk (UHR).A literature search (1970-July 2015) was performed in PubMed, PsychINFO, Medline, Embase, and ISI Web of Science, using the search terms 'social cognition', 'theory of mind', 'emotion recognition', 'attributional style', 'social knowledge', 'social perception', 'empathy', 'at risk mental state', 'clinical high risk', 'psychosis prodrome', and 'ultra high risk'. The pooled effect size (Cohen's D) and the effect sizes for each domain of social cognition were calculated. A random effects model with 95% confidence intervals was used.Seventeen studies were included in the analysis. The overall significant effect was of medium magnitude (d = 0.52, 95% Cl = 0.38-0.65). No moderator effects were found for age, gender and sample size. Sub-analyses demonstrated that individuals in the UHR phase show significant moderate deficits in affect recognition and affect discrimination in faces as well as in voices and in verbal Theory of Mind (TOM). Due to an insufficient amount of studies, we did not calculate an effect size for attributional bias and social perception/ knowledge. A majority of studies did not find a correlation between social cognition deficits and transition to psychosis, which may suggest that social cognition in general is not a useful marker for the development of psychosis. However some studies suggest the possible predictive value of verbal TOM and the recognition of specific emotions in faces for the transition into psychosis. More research is needed on these subjects.The published literature indicates consistent general impairments in social cognition in people in the UHR phase, but only very specific impairments seem to predict transition to psychosis

Measuring empathy in schizophrenia:The Empathic Accuracy Task and its correlation with other empathy measures

Introduction: Empathy is an interpersonal process impaired in schizophrenia. Past studies have mainly used questionnaires or performance-based tasks with static cues to measure cognitive and affective empathy. We used the Empathic Accuracy Task (EAT) designed to capture dynamic aspects of empathy by using videoclips in which perceivers continuously judge emotionally charged stories. We compared individuals with schizophrenia with a healthy comparison group and assessed correlations among EAT and three other commonly used empathy measures. Method: Patients (n = 92) and a healthy comparison group (n = 42) matched for age, gender and education completed the EAT, the Interpersonal Reactivity Index, Questionnaire of Cognitive and Affective Empathy and Faux Pas. Differences between groups were analyzed and correlations were calculated between empathy measurement instruments. Results: The groups differed in EAT performance, with the comparison group outperforming patients. A moderating effect was found for emotional expressivity of the target: while both patients and the comparison group scored low when judging targets with low expressivity, the comparison group performed better than patients with more expressive targets. Though there were also group differences on the empathy questionnaires, EAT performance did not correlate with questionnaire scores. Conclusions: Individuals with schizophrenia benefit less from the emotional expressivity of other people than the comparison group, which contributes to their impaired empathic accuracy. The lack of correlation between the EAT and the questionnaires suggests a distinction between self-report empathy and actual empathy performance. To explore empathic difficulties in real life, it is important to use instruments that take the interpersonal perspective into account. (C) 2019 Published by Elsevier B.V

Metacognitive Reflection and Insight Therapy (MERIT) with a Patient with Persistent Negative Symptoms

Metacognition comprises a spectrum of mental activities involving thinking about thinking. Metacognitive impairments may sustain and trigger negative symptoms in people with schizophrenia. Without complex ideas of the self and others, there may be less reason to pursue goal-directed activities and less ability to construct meaning in daily activities, leading to the experience of negative symptoms. As these symptoms tend to be nonresponsive to pharmacotherapy and other kinds of treatment metacognition might be a novel treatment target; improvement of metacognition might lead to improvements in negative symptoms. One therapy that seeks to promote metacognition is the Metacognitive Reflection and Insight Therapy (MERIT). In this study, a case is presented in which a first episode patient with severe negative symptoms is treated with MERIT. A case illustration and the eight core principles of MERIT are presented. Independent assessments of metacognition and negative symptoms before and after therapy show a significant increase of metacognition and decrease of negative symptoms over the course of 40 weeks

An Integrative-Relational Approach in Schizophrenia: From Philosophical Principles to Mentalization-Based Practice

In this paper, we explore psychosis and schizophrenia as prototype disturbances, where mentalizing failures are widely seen. We attempt to describe how the process of rekindling mentalizing within attachment relationships (here, the patient-therapist relationship) can have a protective effect not just on the onset of the disturbance, but also when psychosis is already actively installed. We start by discussing mentalizing in training, practice and supervision. We also try to understand it contextually, as a relational concept, within the history of psychological therapies

Metacognition in psychotic disorders: from concepts to intervention

BACKGROUND: Persons with a psychotic disorder commonly experience difficulties with what is considered to be metacognitive capacity. In this article we discuss several definitions of this concept, the measurement instruments involved and the clinical interventions that target this concept.AIM: To present a review of various frequently used definitions of metacognition and related concepts and to describe the measurement instruments involved and the treatment options available for improving the metacognitive capacity of persons with a psychotic disorder.METHOD: We present an overview of several definitions of metacognition in psychotic disorders and we discuss frequently used measurement instruments and treatment options. The article focuses on recent developments in a model devised by Semerari et al. The measurement instrument involved (Metacognition Assessment Scale - A) is discussed in terms of it being an addition to existing methods.RESULTS: On the basis of the literature it appears that metacognition and related concepts are measurable constructs, although definitions and instruments vary considerably. The new conceptualisation of social information processing also leads to the development of a new form of psychotherapy that aims to help patients suffering from psychotic disorders to improve metacognitive capacity.CONCLUSION: There seems to be evidence that metacognitive abilities are a possible target for treatment, but further research is needed.</p

Metacognitie bij psychotische stoornissen: van concept naar interventie

ACHTERGROND: Mensen met een psychotische stoornis ondervinden veelal problemen in wat kan worden beschreven als de metacognitieve vaardigheden. Er zijn verscheidene definities van dit concept, alsmede meetinstrumenten en klinische interventies die zich op dit concept richten. DOEL: Een overzicht bieden van enkele veelgebruikte definities van metacognitie en gerelateerde concepten, alsmede de bijbehorende meetinstrumenten en behandelopties om metacognitie bij mensen met een psychotische stoornis te verbeteren. METHODE: Aan de hand van de literatuur een overzicht geven van de verschillende definities van metacognitie bij psychotische stoornissen, alsmede veelgebruikte meetinstrumenten en behandelmethoden. De nadruk ligt hierbij op de recente ontwikkelingen in een model van Semerari en collega’s met bijbehorende meetinstrument (de Metacognition Assessment Scale – A). We bekijken hoe dit een toevoeging kan zijn op de bestaande methoden. RESULTATEN: Op basis van de literatuur lijken de concepten metacognitie en gelieerde concepten meetbare constructen, alhoewel de definities en meetinstrumenten heterogeen blijken. De nieuwe conceptualisering van de sociale informatieverwerking leidt tevens tot de ontwikkeling van een nieuwe vorm van psychotherapie, die gericht is op het verbeteren van de metacognitieve vaardigheden bij mensen met een psychotische stoornis. CONCLUSIE: Er lijken aanwijzingen dat metacognitieve vaardigheden een doel van behandeling kunnen zijn, maar meer onderzoek is noodzakelijk.
