Gaze-speech coordination during social interaction in Parkinson's disease.

BACKGROUND: Parkinson's disease (PD) can affect social interaction and communication as well as motor and cognitive processes. Speech is affected in PD, as is the control of voluntary eye movements which are thought to play an important role in 'turn taking' in conversation. AIMS: This study aimed to measure eye movements during spoken conversation in PD to assess whether differences in patterns of eye gaze are linked to disrupted turn taking and impaired communication efficiency. METHODS & PROCEDURE: Eleven participants with mild PD and 14 controls completed a two-player guessing game. During each 3 min game turn, one of the players had to guess the names of as many objects as possible based only on the other player's description. Eye movements were recorded simultaneously in both participants using mobile eye trackers along with speech onset and offset times. OUTCOMES & RESULTS: When people with PD played the role of describer, the other player guessed fewer objects compared to when controls described objects. When guessing objects, people with PD performed just as well as controls. Analysis of eye fixations showed that people with PD made longer periods of fixation on the other player's face relative to controls and a lower number of such 'gaze on face' periods. CONCLUSIONS & IMPLICATIONS: A combination of oculomotor, cognitive and speech abnormalities may disrupt communication in PD. Better public awareness of oculomotor, speech and other deficits in the condition could improve social connectedness in people with Parkinson's. WHAT THIS PAPER ADDS: What is already known on this subject? Parkinson's disease is known to affect the control of voluntary eye movements. Direction of eye gaze is important in spoken conversation as a cue to turn-taking, but no studies have examined whether eye movements are different during communication in people with Parkinson's. What this paper adds to existing knowledge? People with Parkinson's showed longer periods of eye fixation during conversations compared to controls. Delays and overlaps between speech turns were also affected in patients. What are the clinical implications of this work? Better knowledge of the effect of the disease on eye gaze control amongst clinicians may help improve communication and social connectedness for patients in the future.

Leprosy rash precipitated by immunotherapy for suspected inflammatory neuropathy.

Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae complex, causing skin and nerve lesions with potential for permanent disability. Leprosy can be overlooked in Western settings, as it is more prevalent in low-income and middle-income countries. We describe a 38-year-old woman with a 4-year history of progressive numbness of the left hand incorrectly diagnosed as multifocal acquired demyelinating sensory and motor neuropathy on the basis of clinical and neurophysiological findings. Treatment with empirical weekly corticosteroid followed by intravenous immunoglobulin resulted in the sudden development of a widespread rash; we then diagnosed borderline lepromatous leprosy on skin biopsy. We postulate that the immune treatments induced a temporary state of immune tolerance followed by a rebound of a T cell-mediated immune response resulting in a type 1 immunological response.

Pastoral Narrative Disclosure: The Development and Evaluation of an Australian Chaplaincy Intervention Strategy for Addressing Moral Injury.

This paper describes the development and initial chaplaincy user evaluation of 'Pastoral Narrative Disclosure' (PND) as a rehabilitation strategy developed for chaplains to address moral injury among veterans. PND is an empirically informed and integrated intervention comprising eight stages of pastoral counselling, guidance and education that was developed by combining two previously existing therapeutic techniques, namely Litz et al's (2017) 'Adaptive Disclosure' and 'Confessional Practice' (Joob & Kettunen, 2013). The development and results of PND can be categorized into five phases. Phase 1: PND Strategy Formation-based upon extensive international research demonstrating that MI is a complex bio-psycho-social-spiritual syndrome with symptoms sufficiently distinct from post-traumatic stress disorder. The review also provided evidence of the importance of chaplains being involved in moral injury rehabilitation. Phase II: Development and Implementation of 'Moral Injury Skills Training' (MIST)-which involved the majority of available Australian Defence Force (ADF) Chaplains (n = 242/255: 94.9%) completing a basic 'Introduction to Moral Injury' (MIST-1) as well as an 'Introduction to PND' (MIST-2). Phase III: MIST-3-PND-Pilot evaluation-involved a representative chaplaincy cohort (n = 13) undergoing the PND eight-stage strategy to ensure the integrity and quality of PND from a chaplaincy perspective prior to wider implementation. The pilot PND evaluation indicated a favourable satisfaction rating (n = 11/13: 84.6%; M = 4.73/5.0 satisfaction). Phase IV: MIST-3-PND Implementation-involved a larger cohort of ADF Chaplaincy participants (n = 210) completing a revised and finalized PND strategy which was regarded favourably by the majority of ADF Chaplains (n = 201/210: 95.7%; M = 4.73/5.0 satisfaction). Phase V: Summation. In conclusion the positive satisfaction ratings by a significant number of ADF chaplaincy personnel completing MIST-3-PND, provided evidence that chaplains evaluated PND as a suitable counselling, guidance and education strategy, which affirmed its utilisation and justifies further research for using PND to address MI among veterans, that may also prove valuable for other chaplains working in community health and first responder contexts.

Patient-reported symptoms and experience following Guillain-Barré syndrome and related conditions: Questionnaire development and validation.

BACKGROUND: Guillain-Barré syndrome (GBS) is a rare inflammatory peripheral nerve disorder with variable recovery. Evidence is lacking on experiences of people with GBS and measurement of these experiences. OBJECTIVE: We aimed to develop and validate an instrument to measure experiences of people with GBS. DESIGN: We used a cross-sectional design and online self-administered questionnaire survey. Question domains, based on a previous systematic review and qualitative study, covered experiences of GBS, symptom severity at each stage, healthcare and factors supporting or hindering recovery. Descriptive, exploratory factor and reliability analyses and multivariable regression analysis were used to investigate the relationships between variables of interest, explore questionnaire reliability and validity and identify factors predicting recovery. SETTING AND PARTICIPANTS: People with a previous diagnosis of GBS were recruited through a social media advert. RESULTS: A total of 291 responders, of different sexes, and marital statuses, were included, with most diagnosed between 2015 and 2019. Factor analysis showed four scales: symptoms, information provided, factors affecting recovery and care received. Positive social interactions, physical activity including physiotherapy and movement, changes made at home and immunoglobulin treatment were important for recovery. Multivariable models showed that immunoglobulin and/or plasma exchange were significant predictors of recovery. Employment and recovery factors (positive interactions, work support and changes at work or home, physical activity and therapy), though associated with recovery, did not reach statistical significance. CONCLUSION: The questionnaire demonstrated good internal reliability of scales and subscales and construct validity for people following GBS. PATIENT CONTRIBUTION: Patients were involved in developing and piloting the questionnaire.

Visual Attention and Cognitive Archaeology: An Eye-Tracking Study of Palaeolithic Stone Tools.

The study of lithic technology can provide information on human cultural evolution. This article aims to analyse visual behaviour associated with the exploration of ancient stone artefacts and how this relates to perceptual mechanisms in humans. In Experiment 1, we used eye tracking to record patterns of eye fixations while participants viewed images of stone tools, including examples of worked pebbles and handaxes. The results showed that the focus of gaze was directed more towards the upper regions of worked pebbles and on the basal areas for handaxes. Knapped surfaces also attracted more fixation than natural cortex for both tool types. Fixation distribution was different to that predicted by models that calculate visual salience. Experiment 2 was an online study using a mouse-click attention tracking technique and included images of unworked pebbles and 'mixed' images combining the handaxe's outline with the pebble's unworked texture. The pattern of clicks corresponded to that revealed using eye tracking and there were differences between tools and other images. Overall, the findings suggest that visual exploration is directed towards functional aspects of tools. Studies of visual attention and exploration can supply useful information to inform understanding of human cognitive evolution and tool use.

Moral Injury, Betrayal and Retribution: Australian Veterans and the Role of Chaplains.

This paper presents additional qualitative results from Phase 1 of a larger study examining potentially morally injurious events/experiences (PMIE) and/or moral injury (MI) among Australian veterans (Hodgson et al. in J Relig Health 60(5):3061-3089, 2021). It makes specific reference to (1) betrayal and (2) retribution experienced or perpetrated by Australian military veterans during military conflicts and peacekeeping missions. During two veteran seminars conducted in Adelaide, South Australia, a total of 50 veterans were recruited, 10 of whom were willing to be interviewed and audio-recorded about their deployment experiences. Narrative data analysis of veteran transcripts indicated that all participants had engaged in or were exposed to a PMIE/MI of one kind or another, and all had experienced betrayal and/or witnessed or perpetrated retribution. Given the ethical, moral and spiritual issues involved, the role of chaplains in addressing moral injury for the benefit of veterans through the use of 'Pastoral Narrative Disclosure' (PND) is suggested-with a specific focus upon 'restoration' and 'ritual'. Additional research is recommended with regard to acts of betrayal and retribution among veterans, as well as the further development of PND to address PMIE/MI.

The effect of directional social cues on saccadic eye movements in Parkinson's disease.

There is growing interest in how social processes and behaviour might be affected in Parkinson's disease. A task which has been widely used to assess how people orient attention in response to social cues is the spatial cueing task. Socially relevant directional cues, such as a picture of someone gazing or pointing to the left or the right have been shown to cause orienting of visual attention in the cued direction. The basal ganglia may play a role in responding to such directional cues, but no studies to date have examined whether similar social cueing effects are seen in people with Parkinson's disease. In this study, patients and healthy controls completed a prosaccade (Experiment 1) and an antisaccade task (Experiment 2) in which the target was preceded by arrow, eye gaze or pointing finger cues. Patients showed increased errors and response times for antisaccades but not prosaccades. Healthy participants made most anticipatory errors on pointing finger cue trials, but Parkinson's patients were equally affected by arrow, eye gaze and pointing cues. It is concluded that Parkinson's patients have a reduced ability to suppress responding to directional cues, but this effect is not specific to social cues.

Moral Injury, Australian Veterans and the Role of Chaplains: An Exploratory Qualitative Study.

Military personnel deployed to war zones or assigned to other morally challenging military duties are likely to be exposed to potentially morally injurious events (PMIE) that may inflict a moral injury (MI). This qualitative study formed 'Phase 1' of a larger study into PMIEs experienced by Australian veterans and the potential pastoral/spiritual care role of chaplains. Two seminars were conducted that involved 10 veterans being interviewed and audio recorded about their deployment experiences to evaluate whether there was any evidence among Australian veterans of a PMIE. Narrative data analysis indicated that all participants had been exposed to, or were involved in, a PMIE of one kind or another. Seven key themes were identified from the analyzed qualitative data: (i) immoral acts, (ii) death and injury, (iii) betrayal, (iv) ethical dilemmas, (v) disproportionate violence, (vi) retribution and (vii) religious/spiritual issues. Given this preliminary PMIE evidence identified, there is a need for further research, as well as the development of a suitable moral injury assessment scale appropriate for Australian veterans. Furthermore, given the ethical, moral, and spiritual issues involved, the implementation of a rehabilitation program suitable for Australian veterans which can be provided by chaplains is also suggested-namely 'Pastoral Narrative Disclosure.' It is argued that moral injury needs to be recognized, not just as an issue affecting individual personnel and their families, but is also a community health, organizational and government responsibility.

Exploring the experiences of having Guillain-Barré Syndrome: A qualitative interview study.

BACKGROUND: Guillain-Barré syndrome (GBS) is a rare inflammatory disorder affecting the peripheral nerves. Although typically there is full neurological recovery, some people continue to experience residual physical, psychological or social problems longer term. Evidence describing the experiences of people with GBS is limited. OBJECTIVE: We aimed to explore the experiences of people with GBS in the UK. DESIGN: We used qualitative (face-to-face and telephone) interviews to explore experiences of people with GBS. Audio-recorded data were transcribed verbatim and analysed using the Framework Method supported by NVivo 11. SETTING AND PARTICIPANTS: We purposively recruited a sample of 16 volunteers with a prior diagnosis of GBS of varying age, sex, ethnicity, location, marital status, time since diagnosis and length of hospital stay to maximize differences in experience. Interviewees were required to have been discharged from hospital, able to give informed consent, able to speak and understand English and currently resident in the United Kingdom. RESULTS: The key themes arising from the analysis were as follows: the importance of early diagnosis; the experiences of inpatient care; the importance of active support for recovery; the need for communication throughout the course of the illness; the need for greater awareness, knowledge and provision of information by health-care staff; and path to achieving function. CONCLUSION: This is the first qualitative study exploring experiences of people with GBS in the UK through their whole illness journey from onset to recovery. The findings contribute to our understanding of the experiences and support needs of people recovering from GBS.

Eye Movements in the "Morris Maze" Spatial Working Memory Task Reveal Deficits in Strategic Planning.

Analysis of eye movements can provide insights into processes underlying performance of cognitive tasks. We recorded eye movements in healthy participants and people with idiopathic Parkinson disease during a token foraging task based on the spatial working memory component of the widely used Cambridge Neuropsychological Test Automated Battery. Participants selected boxes (using a mouse click) to reveal hidden tokens. Tokens were never hidden under a box where one had been found before, such that memory had to be used to guide box selections. A key measure of performance in the task is between search errors (BSEs) in which a box where a token has been found is selected again. Eye movements were found to be most commonly directed toward the next box to be clicked on, but fixations also occurred at rates higher than expected by chance on boxes farther ahead or back along the search path. Looking ahead and looking back in this way was found to correlate negatively with BSEs and was significantly reduced in patients with Parkinson disease. Refixating boxes where tokens had already been found correlated with BSEs and the severity of Parkinson disease symptoms. It is concluded that eye movements can provide an index of cognitive planning in the task. Refixations on locations where a token has been found may also provide a sensitive indicator of visuospatial memory integrity. Eye movement measures derived from the spatial working memory task may prove useful in the assessment of executive functions as well as neurological and psychiatric diseases in the future.

Moral Injury and Definitional Clarity: Betrayal, Spirituality and the Role of Chaplains.

This article explores the developing definition of moral injury within the current key literature. Building on the previous literature regarding 'Moral Injury, Spiritual Care and the role of Chaplains' (Carey et al. in JORH 55(4):1218-1245, 2016b. doi: 10.1007/s10943-016-0231-x ), this article notes the complexity that has developed due to definitional variations regarding moral injury-particularly with respect to the concepts of 'betrayal' and 'spirituality'. Given the increasing recognition of moral injury and noting the relevance and importance of utilizing a bio-psycho-social-spiritual model, this article argues that betrayal and spirituality should be core components for understanding, defining and addressing moral injury. It also supports the role of chaplains being involved in the holistic care and rehabilitation of those affected by moral injury.

The developmental trajectory of attentional orienting to socio-biological cues.

It has been proposed that the orienting of attention in the same direction as another's point of gaze relies on innate brain mechanisms which are present from birth, but direct evidence relating to the influence of eye gaze cues on attentional orienting in young children is limited. In two experiments, 137 children aged 3-10 years old performed an adapted pro-saccade task with centrally presented uninformative eye gaze, finger pointing and arrow pre-cues which were either congruent or incongruent with the direction of target presentations. When the central cue overlapped with presentation of the peripheral target (Experiment 1), children up to 5 years old had difficulty disengaging fixation from central fixation in order to saccade to the target. This effect was found to be particularly marked for eye gaze cues. When central cues were extinguished simultaneously with peripheral target onset (Experiment 2), this effect was greatly reduced. In both experiments finger pointing cues (image of pointing index finger presented at fixation) exerted a strong influence on saccade reaction time to the peripheral stimulus for the youngest group of children (<5 years). Overall the results suggest that although young children are strongly engaged by centrally presented eye gaze cues, the directional influence of such cues on overt attentional orienting is only present in older children, meaning that the effect is unlikely to be dependent upon an innate brain module. Instead, the results are consistent with the existence of stimulus-response associations which develop with age and environmental experience.

Moral Injury, Spiritual Care and the Role of Chaplains: An Exploratory Scoping Review of Literature and Resources.

This scoping review considered the role of chaplains with regard to 'moral injury'. Moral injury is gaining increasing notoriety. This is due to greater recognition that trauma (in its various forms) can cause much deeper inflictions and afflictions than just physiological or psychological harm, for there may also be wounds affecting the 'soul' that are far more difficult to heal-if at all. As part of a larger research program exploring moral injury, a scoping review of literature and other resources was implemented utilising Arksey and O'Malley's scoping method (Int J Soc Res Methodol 8(1):19-32, 2005) to focus upon moral injury, spirituality (including religion) and chaplaincy. Of the total number of articles and/or resources noting the term 'moral injury' in relation to spiritual/religious issues (n = 482), the results revealed 60 resources that specifically noted moral injury and chaplains (or other similar bestowed title). The majority of these resources were clearly positive about the role (or the potential role) of chaplains with regard to mental health issues and/or moral injury. The World Health Organization International Classification of Diseases: Australian Modification of Health Interventions to the International Statistical Classification of Diseases and related Health problems (10th revision, vol 3-WHO ICD-10-AM, Geneva, 2002), was utilised as a coding framework to classify and identify distinct chaplaincy roles and interventions with regard to assisting people with moral injury. Several recommendations are made concerning moral injury and chaplaincy, most particularly the need for greater research to be conducted.

Green neutrophil and monocyte inclusions - time to acknowledge and report.

Bright green inclusions in neutrophils have been reported as a sign of impending patient death. Here we report a series of 20 patients in whom green inclusions were identified in neutrophils or monocytes. Thirteen (65%) of the patients died within days of the detection of the inclusions. A common feature to almost all patients was ischaemic or hypoxic hepatitis which, in fatal cases, was associated with lactic acidosis. Light and electron microscopy indicated that the inclusions were lipid-rich, probably derived from lipofuscin-like material released from necrotic liver parenchymal cells. The majority of patients were known to be seriously ill at the time of detection of neutrophil inclusions. We recommend that the detection of green inclusions, which we refer to as 'critical green inclusions', is acknowledged and reported by laboratories and correlated with clinical findings.

You are in charge now: exploration of educational relationships between anaesthetic trainees and their supervising specialists.

Background: Much of the education during anaesthesia training occurs in the workplace where trainees work under the close supervision of a more senior anaesthetist. Trainee anaesthetists are exposed to multiple supervisors with whom they form educational and supervisory relationships over the course of their training. Surprisingly little research has been conducted to explore the factors behind the development and maintenance of these relationships. This study explores the process of how education occurs in the workplace by examining the relationship from the perspective of both trainees and specialists. Methods: This is an exploratory qualitative study. Eight trainee and 10 specialist anaesthetists participated in an individual semi-structured interview. The data were analysed thematically by each of the authors to generate themes. Results: Six themes were identified in the analysis: (1) sizing up; (2) negotiated autonomy; (3) working closely together; (4) workplace practices; (5) education being valued; and (6) gender. A conceptual model to illustrate the relationships between the six themes was developed. Conclusions: Supervisory relationships were viewed positively by participants despite impediments such as lack of continuity and busy clinical environments. But there were tensions, particularly in balancing trainee autonomy with patient safety. A nuanced 'sizing up' process, with negotiation of autonomy, was described by both supervisors and trainees. Our findings may support supervisory relationships to reach this ideal more effectively.

Assessing the Human Rights Framework on Private Health Care Actors and Economic Inequality.

Private actors' involvement in health care financing, provision, and governance contributes to economic inequality. This paper provides an overview of emerging normative trends regarding private actors' involvement in health care by reviewing and critically analyzing international and regional human rights standards on the right to the highest attainable standard of physical and mental health. Specifically, we survey statements from United Nations human rights treaty bodies and recent jurisprudence of the African Commission on Human and Peoples' Rights that discuss private actors' involvement in health care. We then identify strengths and weaknesses of the current international human rights law framework to address the human rights and inequality impacts of private health care actors, before concluding with a series of recommendations to further develop existing standards.

A historical analysis of single-stage γ knife radiosurgical treatment for large arteriovenous malformations: evolution and outcomes.

BACKGROUND: Large arteriovenous malformations (AVMs) remain challenging and difficult to treat, reflected by evolving strategies developed from simple radiosurgical plans, to encompass embolization and, recently, staged volume treatments. To establish a baseline for future practice, we reviewed our clinical experience. METHOD: The outcomes for 492 patients (564 treatments) with AVMs >10 cm(3) treated by single-stage radiosurgery were retrospectively analysed in terms of planning, previous embolization and size. RESULTS: Twenty-eight percent of the patients presented with haemorrhage at a median age of 29 years (range: 2-75). From 1986 to 1993 (157 patients) plans were simplistic, based on angiography using a median of 2 isocentres and a marginal dose of 23 Gy covering 45-70% of the AVM (median volume 15.7 cm(3)). From 1994 to 2000 (225 patients) plans became more sophisticated, a median of 5 isocentres was used, covering 64-95% of the AVM (14.6 cm(3)), with a marginal dose of 21 Gy. Since 2000, MRI has been used with angiography to plan for 182 patients. Median isocentres increased to 7 with similar coverage (62-94%) of the AVM (14.3 cm(3)) and marginal dose of 21 Gy. Twenty-seven percent, 30% and 52% of patients achieved obliteration at 4 years, respectively. The proportion of prior embolization increased from 9% to 44% during the study. Excluding the embolized patients, improvement in planning increased obliteration rates from 28% to 36% and finally 63%. Improving treatment plans did not significantly decrease the rate of persisting radiation-induced side effects (12-16.5%). Complication rate rose with increasing size. One hundred and twenty-three patients underwent a second radiosurgical treatment, with a 64% obliteration rate, and mild and rare complications (6%). CONCLUSIONS: Better visualization of the nidus with multimodality imaging improved obliteration rates without changing morbidity. Our results support the view that prior embolization can make interpretation of the nidus more difficult, reducing obliteration rate. It will be important to see how results of staged volume radiosurgery compare with this historical material.

Applying the British picture vocabulary scale to estimate premorbid cognitive ability in adults.

Estimating premorbid cognitive ability is an essential part of assessment as well as being an important consideration in research. The most widely used approach to premorbid assessment, The National Adult Reading Test (NART), relies on word reading ability. However, this can be problematic in patients where communication is impaired. This research assessed the effectiveness of a receptive vocabulary test, the British Picture Vocabulary Scale II (BPVS) as an alternative. Correlations were found between the BPVS, NART and the Weschler Abbreviated Scale of Intelligence (WASI) in 87 healthy participants. Regression equations were calculated relating NART and BPVS raw scores to IQ scores in the healthy sample. WASI, NART and BPVS scores were also obtained in 19 patients with varying neurological etiology as part of their routine assessment. Results showed that 18 out of 19 patients obtained BPVS derived IQ scores similar to or higher than their WASI IQ. Whereas mean BPVS derived IQ did not differ significantly between the standardization and clinical samples, WASI IQ scores were lower in the patient group. The findings suggest that the BPVS II 'holds' after acquired cognitive impairment and is a promising alternative method for estimating premorbid IQ in patients who have difficulties reading or verbalizing.

Act quickly, decide later: long-latency visual processing underlies perceptual decisions but not reflexive behavior.

Humans largely guide their behavior by their visual representation of the world. Recent studies have shown that visual information can trigger behavior within 150 msec, suggesting that visually guided responses to external events, in fact, precede conscious awareness of those events. However, is such a view correct? By using a texture discrimination task, we show that the brain relies on long-latency visual processing in order to guide perceptual decisions. Decreasing stimulus saliency leads to selective changes in long-latency visually evoked potential components reflecting scene segmentation. These latency changes are accompanied by almost equal changes in simple RTs and points of subjective simultaneity. Furthermore, we find a strong correlation between individual RTs and the latencies of scene segmentation related components in the visually evoked potentials, showing that the processes underlying these late brain potentials are critical in triggering a response. However, using the same texture stimuli in an antisaccade task, we found that reflexive, but erroneous, prosaccades, but not antisaccades, can be triggered by earlier visual processes. In other words: The brain can act quickly, but decides late. Differences between our study and earlier findings suggesting that action precedes conscious awareness can be explained by assuming that task demands determine whether a fast and unconscious, or a slower and conscious, representation is used to initiate a visually guided response.
