Emotion regulation in psychopathy

Emotion processing is known to be impaired in psychopathy, but less is known about the cognitive mechanisms that drive this. Our study examined experiencing and suppression of emotion processing in psychopathy. Participants, violent offenders with varying levels of psychopathy, viewed positive and negative images under conditions of passive viewing, experiencing and suppressing. Higher scoring psychopathics were more cardiovascularly responsive when processing negative information than positive, possibly reflecting an anomalously rewarding aspect of processing normally unpleasant material. When required to experience emotional response, by ‘getting into the feeling’ of the emotion conveyed by a negative image, higher factor 1 psychopathic individuals showed reduced responsiveness, suggesting that they were less able to do this. These data, together with the absence of corresponding differences in subjective self-report might be used to inform clinical strategies for normalising emotion processing in psychopathic offenders to improve treatment outcome, and reduce risk amongst this client group

Relational response: Preservice teachers providing writing feedback in three middle school partnerships

Providing meaningful feedback to student writers is a nuanced, fully human endeavor. Thus, teaching preservice teachers, in all disciplines, to respond to students’ writing is a complex task, one that requires intentional instruction and practice. In this article, we use practitioner inquiry to analyze our experiences and teaching approaches with preservice teachers who provided feedback to middle school writers through three public school partnerships. The partnerships employed varied modes of communication, including digital platforms, paper notebooks, letter writing, one-to-one tutoring, and face-to-face school visits. Response patterns suggest authentic experiences that explicitly teach and support writing practice spur the ability of preservice teachers in crafting relational, generative feedback to student writers while considering the affective experience

Metabolic Requirements of Farmers/Ranchers Performing Simulated Occupational Tasks: Recommendations for Cardiovascular Rehabilitation

Current ACSM guidelines for cardiac rehabilitation (rehab) return to work state that exercise training should mimic the muscle groups, movements, and energy systems utilized in a patient’s occupational tasks. The aims of this study were to evaluate the metabolic costs of typical farming/ranching tasks, determine the pattern of movement and muscle groups involved in these tasks, and determine the approximate duration of these tasks. Methods: Participants (n=29) were employed in the farming/ranching field and ranged in aged from 18-57 years. The participants performed four tasks: loading 10 hay bales, digging a fence post hole, filling eight seed hoppers, and shoveling grain. Results: Ranges for mean metabolic equivalent (MET) levels of the tasks were 5.9-7.6 while respiratory exchange ratio (RER) values ranged from .85-.93. Mean times (min:sec) for task duration were 1:42-3:34. Conclusion: MET levels recorded in this study are in agreement with the Compendium of Physical Activities for farming tasks and meet the standard requirements for cardiovascular training in cardiac rehab (~ 8 METS). However, these tasks are of high intensity and require an exercise prescription based on specificity of training for the muscle groups and energy systems involved. In accordance to ACSM guidelines, this study includes recommendations for exercise prescription specific to supervised resistance training appropriate for a farmer/rancher population in cardiac rehab settings

Experiences of care planning in England: interviews with patients with long term conditions.

BACKGROUND: The prevalence and impact of long term conditions continues to rise. Care planning for people with long term conditions has been a policy priority in England for chronic disease management. However, it is not clear how care planning is currently understood, translated and implemented in primary care. This study explores experience of care planning in patients with long term conditions in three areas in England. METHODS: We conducted semi-structured interviews with 23 predominantly elderly patients with multiple long term conditions. The interviews were designed to explore variations in and emergent experiences of care planning. Qualitative analysis of interview transcripts involved reflexively coding and re-coding data into categories and themes. RESULTS: No participants reported experiencing explicit care planning discussions or receiving written documentation setting out a negotiated care plan and they were unfamiliar with the term 'care planning'. However, most described some components of care planning which occurred over a number of contacts with health care professionals which we term "reactive" care planning. Here, key elements of care planning including goal setting and action planning were rare. Additionally, poor continuity and coordination of care, lack of time in consultations, and patient concerns about what was legitimate to discuss with the doctor were described. CONCLUSIONS: Amongst this population, elements of care planning were present in their accounts, but a structured, comprehensive process and consequent written record (as outlined in English Department of Health policy) was not evident. Further research needs to explore the advantages and disadvantages of different approaches to care planning for different patient groups.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

Feeding behaviour, risk-sensitivity and response control:Effects of 5-HT2C receptor manipulations

People, like animals, tend to choose the variable option when given the choice between a fixed and variable delay to reward where, in the variable delay condition, some rewards are available immediately (Laura-Jean et al. 2019 Phil. Trans. R. Soc. B374, 20180141. (doi:10.1098/rstb.2018.0141)). This bias has been suggested to reflect evolutionary pressures resulting from food scarcity in the past placing a premium on obtaining food quickly that can win out against the risks of sometimes sustaining longer delays to food. The psychologies mediating this effect may become maladaptive in the developed world where food is readily available contributing, potentially, to overeating and obesity. Here, we report our development of a novel touchscreen task in mice allowing comparisons of the impact of food delay and food magnitude across species. We show that mice exhibit the typical preference, as shown by humans, for variable over fixed delays to rewards but no preference when it comes to fixed versus variable reward amounts and further show that this bias is sensitive to manipulations of the 5-HT2C receptor, a key mediator of feeding and impulse control. We discuss the data in terms of the utility of the task to model the psychologies and underlying brain mechanisms impacting on feeding behaviours. This article is part of the theme issue ‘Risk taking and impulsive behaviour: fundamental discoveries, theoretical perspectives and clinical implications’

The best of the UK? A report on the value and future of UK databases in the health and social care fields: a systematic map protocol

INTRODUCTION: This protocol covers the first part of a two-part project funded by the Health Libraries Group and the University Health and Medical Librarians Group. It details the proposed methodology for a systematic map of the literature relating to UK bibliographic databases in the fields of health and social care. The aim of this mapping exercise is to consider ways in which UK bibliographic databases are described, considered and discussed in the published and unpublished literature. In doing so, we hope to gain a clearer sense of the ways in which UK bibliographic databases are used and viewed by the research community. It also enables the identification of any gaps in the literature for further research and discussion. This topic is important because UK databases are generally underused by researchers in the UK context and some databases are at risk of closure. A lack of access to UK databases means that researchers may miss relevant UK evidence when identifying an evidence base. / METHOD: Systematic Map. / ANALYSIS: The authors will present a narrative description of the literature relating to UK bibliographic databases in the fields of health and social care. They will use tables to present descriptive information about the literature (eg, frequency tables) and use cross-tabulations to demonstrate intersecting themes. Separately, guidance on how to use the resources (eg, areas of unique content, updating frequencies, unique truncation symbols) will be sought from stakeholders and reported alongside the report narrative as a guide to usage

On Determining Dead Layer and Detector Thicknesses for a Position-Sensitive Silicon Detector

In this work, two particular properties of the position-sensitive, thick silicon detectors (known as the "E" detectors) in the High Resolution Array (HiRA) are investigated: the thickness of the dead layer on the front of the detector, and the overall thickness of the detector itself. The dead layer thickness for each E detector in HiRA is extracted using a measurement of alpha particles emitted from a $^{212}$Pb pin source placed close to the detector surface. This procedure also allows for energy calibrations of the E detectors, which are otherwise inaccessible for alpha source calibration as each one is sandwiched between two other detectors. The E detector thickness is obtained from a combination of elastically scattered protons and an energy-loss calculation method. Results from these analyses agree with values provided by the manufacturer.Comment: Accepted for publication in Nuclear Instruments and Methods in Physics Researc

Effects of 5-HT2C, 5-HT1A receptor challenges and modafinil on the initiation and persistence of gambling behaviours

Rationale Problematic patterns of gambling are characterised by loss of control and persistent gambling often to recover losses. However, little is known about the mechanisms that mediate initial choices to begin gambling and then continue to gamble in the face of losing outcomes. Objectives These experiments first assessed gambling and loss-chasing performance under different win/lose probabilities in C57Bl/6 mice, and then investigated the effects of antagonism of 5-HT2CR with SB242084, 5-HT1AR agonism with 8-OH-DPAT and modafinil, a putative cognitive enhancer. Results As seen in humans and other species, mice demonstrated the expected patterns of behaviour as the odds for winning were altered increasing gambling and loss-chasing when winning was more likely. SB242084 decreased the likelihood to initially gamble, but had no effects on subsequent gambling choices in the face of repeated losses. In contrast, 8-OH-DPAT had no effects on choosing to gamble in the first place, but once started 8-OH-DPAT increased gambling choices in a dose-sensitive manner. Modafinil effects were different to the serotonergic drugs in both decreasing the propensity to initiate gambling and chase losses. Conclusions We present evidence for dissociable effects of systemic drug administration on different aspects of gambling behaviour. These data extend and reinforce the importance of serotonergic mechanisms in mediating discrete components of gambling behaviour. They further demonstrate the ability of modafinil to reduce gambling behaviour. Our work using a novel mouse paradigm may be of utility in modelling the complex psychological and neurobiological underpinnings of gambling problems, including the analysis of genetic and environmental factors
