Attentional biases have been posited as one of the key mechanisms underlying the development and maintenance of chronic pain and co-occurring internalizing mental health symptoms. Despite this theoretical prominence, a comprehensive understanding of the nature of biased attentional processing in chronic pain and its relationship to theorized antecedents and clinical outcomes is lacking, particularly in youth. This study used eye-tracking to assess attentional bias for painful facial expressions and its relationship to theorized antecedents of chronic pain and clinical outcomes. Youth with chronic pain (n = 125) and without chronic pain (n = 52) viewed face images of varying levels of pain expressiveness while their eye gaze was tracked and recorded. At baseline, youth completed questionnaires to assess pain characteristics, theorized antecedents (pain catastrophizing, fear of pain, and anxiety sensitivity), and clinical outcomes (pain intensity, interference, anxiety, depression, and posttraumatic stress). For youth with chronic pain, clinical outcomes were reassessed at 3 months to assess for relationships with attentional bias while controlling for baseline symptoms. In both groups, youth exhibited an attentional bias for painful facial expressions. For youth with chronic pain, attentional bias was not significantly associated with theorized antecedents or clinical outcomes at baseline or 3-month follow-up. These findings call into question the posited relationships between attentional bias and clinical outcomes. Additional studies using more comprehensive and contextual paradigms for the assessment of attentional bias are required to clarify the ways in which such biases may manifest and relate to clinical outcomes.

Children's heightened attention to pain and parental narrative style have been linked to the development of negatively-biased pain memories in children (i.e., recalling higher levels of pain and fear than initially reported, which robustly predicts maladaptive pain outcomes). However, the interplay between child attention bias and parental narrative style remains to be assessed. This study aims to fill this gap using enhanced paradigms assessing children's cognitive biases for cues signaling actual pain. Healthy school children (N = 63; 9-15 years old) received painful heat stimuli while performing a spatial cueing task measuring attention bias to cues signaling actual pain. Parent-child interaction upon completion of the painful task, was coded for parental narrative style (i.e., elaboration, repetition and evaluation). Children's pain-related memories were elicited two weeks later. Findings indicated that children showed an attention bias to cues signaling pain. Furthermore, children who were hypervigilant to pain cues benefitted from parents elaborating more about the pain experience, while children who avoided pain cues developed more negatively-biased pain memories if parents had a more elaborative style compared to a more evaluative parental style. In conclusion, this study suggests that optimal ways to talk about children's pain depend upon child characteristics (i.e., children's attention bias to pain).

The risk of being targeted by a damaging attack is increased when medical devices are used which rely on unmaintained legacy software that cannot be replaced and may have publicly known vulnerabilities. This review aims to provide insight into solutions presented in the literature that mitigate risks caused by legacy software on medical devices. We performed a scoping review by categorising and analysing the contributions of a selection of articles, taken from a literature set discovered through bidirectional citation searching. We found 18 solutions, each fitting at least one of the categories of intrusion detection and prevention, communication tunnelling or hardware protections. Approaches taken include proxying Bluetooth communication through smartphones, behaviour-specification based anomaly detection and authenticating signals based on physical characteristics. These solutions are applicable to various use-cases, ranging from securing pacemakers to medical sensor networks. Most of the solutions are based on intrusion detection and on tunnelling insecure wireless communications. These technologies have distinct application areas, and the decision which one is most appropriate will depend on the type of medical device.

Contains fulltext : 219064.pdf (Publisher’s version ) (Closed access), Children's experience of chronic pain is influenced by the psychological and behavioural responses of their parents. However, the majority of research has been cross-sectional, precluding examination of how these dynamic relationships unfold over time. This study used a microlongitudinal design to examine the daily relationships between parent mood and protective responses and child chronic pain. We also examined the moderating roles of child and parent pain catastrophizing to determine how the affective-motivational context may alter the influence of parent factors. Participants included 95 youth with idiopathic chronic pain (Mage = 14.08; 71.6% female) and their parents. At baseline, parents and youth reported on their catastrophic thinking about child pain. For 7 consecutive days, parents completed daily assessments of their mood and protective responses, while youth completed assessments of their pain intensity, unpleasantness, and interference. Multilevel path analyses were conducted. At a daily level, greater parent protectiveness significantly predicted higher youth pain unpleasantness, interference, and intensity; more negative parent mood significantly predicted higher youth pain intensity and unpleasantness. Higher baseline youth pain catastrophizing predicted a stronger daily association between parent mood and youth pain unpleasantness and intensity. Higher baseline parent pain catastrophizing predicted a weaker daily association between parent protectiveness and youth pain interference. Findings suggest that parent mood and protective responses are dynamic, daily predictors of child pain. Findings also underscore the importance of addressing parents' daily mental health and protectiveness, among youth with chronic pain, and suggest different intervention targets depending on levels of child and parent catastrophizing.
