Stroke results in various cognitive and motor impairments. The most frequent cognitive problem is spatial and non-spatial attention, typically caused by unilateral brain lesion. Attention is typically assessed with several different paper-and-pencil tests, which have long been criticized for their lack of theoretical basis, their limited ecological validity to deficits experienced in daily life, and their lack of measurement sensitivity (Appelros et al., 2004; Azouvi, 2017). Here, our global aim was to develop an innovative integrative serious game in an immersive environment. The REASmash, combines the evaluation of spatial attention, non-spatial attention, and motor performance. We present the spatial and non-spatial cognitive attention evaluation results.
Participants and Methods:
Eighteen first stroke individuals and 40 age-match healthy controls were assessed on the REASmash. They were instructed to find a target mole presented amongst distractor moles. The stimulus array consisted of a grid of 6 columns and 4 rows of molehills, from which the target and 11, 17 and 23 distractors moles could randomly appear, in two search conditions (single feature condition and saliency condition). Responses were made with the ipsilesional hand for individuals with stroke and with the dominant hand for the healthy controls. Participants were evaluated also with two standardized clinical tests of attention; the hearts cancellation task of the Oxford Cognitive Screen, and the visual scanning subtest of the Test for Attentional Performance.
Results:
Validation results showed significant and strong correlations between the REASmash and the two reference tests, with the REASmash showing high sensitivity and specificity (i.e., the correct identification of the post-stroke vs. control individuals). The REASmash also showed significant and strong test/re-test reliability. We additionally evaluated user experience using the UEQ, and the results showed excellent attractiveness and novelty, and good stimulation and efficiency.
Conclusions:
In conclusion, the REASmash is a novel immersive virtual environment serious game that is valid, sensitive, and usable. It provides a new diagnosis measure spatial and non-spatial attention impairment.
Executive functions (EFs) refer to a set of top-down cognitive processes that are fundamental for the control of goal directed behaviours (Lezak et al., 2004). Inhibition (the capacity to ignore irrelevant information) and selective attention (the capacity to selectively focus on relevant information) are considered as the core components of EFs (Barkley, 2001; Veer et al., 2017). EFs can be impaired following brain damage (Chung et al., 2013) and they are traditionally assessed individually, using paper-and-pencil tests that have long been criticized for their ecological and sensitivity limitations (Dugbartey et al., 1999; Miyake et al., 2000). Here we developed a serious game in immersive virtual reality to measure inhibition and selective attention based on the go/no-go paradigm and the D2 Test.
Participants and Methods:
Sixty healthy participants were asked to perform a series of tasks, where in each task, the target was a mole wearing a coloured helmet. In task A, either the target or a distractor bomb was presented. The participants had to respond to the target and inhibit a response to the bomb. In task B, the target was presented with distractor moles wearing different coloured helmets. The two tasks could also be combined, task AB, where the target was presented with distractors (as in task B) versus the bomb was presented with distractor moles. All the stimuli appeared from four molehills aligned to sagittal axis (near to far from the participant). Responses were made with the dominant hand in task A and with both tasks in tasks B and AB. The participants were instructed to hit the target with a virtual hammer.
Results:
Response time analysis showed that in tasks A, B and AB, participants were slower to respond to the far compared to near targets. In task B and AB, participants were additionally slower to respond to the left compared right targets. Significant interactions between laterality and proximity for tasks B and AB showed that the participants were significantly slower to response to left vs right target in both far and near conditions. All participants were able to inhibit responses to the bomb and distractor stimuli.
Conclusions:
In conclusion, we have developed a novel serious game in immersive virtual reality for the assessment of inhibition and selective attention, both as individual tests and as a combined test. Future studies will test patients with executive dysfunction to test the validity of this new serious game.
Psychosis is a major mental illness with first onset in young adults. The prognosis is poor in around half of the people affected, and difficult to predict. The few tools available to predict prognosis have major weaknesses which limit their use in clinical practice. We aimed to develop and validate a risk prediction model of symptom non-remission in first-episode psychosis.
Method
Our development cohort consisted of 1027 patients with first-episode psychosis recruited between 2005 to 2010 from 14 early intervention services across the National Health Service in England. Our validation cohort consisted of 399 patients with first-episode psychosis recruited between 2006 to 2009 from a further 11 English early intervention services. The one-year non-remission rate was 52% and 54% in the development and validation cohorts, respectively. Multivariable logistic regression was used to develop a risk prediction model for non-remission, which was externally validated.
Result
The prediction model showed good discrimination (C-statistic of 0.74 (0.72, 0.76) and adequate calibration with intercept alpha of 0.13 (0.03, 0.23) and slope beta of 0.99 (0.87, 1.12). Our model improved the net-benefit by 16% at a risk threshold of 50%, equivalent to 16 more detected non-remitted first-episode psychosis individuals per 100 without incorrectly classifying remitted cases.
Conclusion
Once prospectively validated, our first episode psychosis prediction model could help identify patients at increased risk of non-remission at initial clinical contact.
Children with asthma face serious mental health risk, but the pathways remain unclear. This study aimed to examine bullying victimisation and perpetration in children with asthma and a comparison sample without a chronic health condition, and the role of bullying in moderating psychosocial adjustment outcomes for those with asthma. A sample of children with (n = 24) and without asthma (n = 39), and their parents, were recruited from hospital clinics. Parents rated children’s psychosocial adjustment; children provided self-report of bullying victimisation and perpetration; from which co-occurring bully/victim status was derived. No differences in mean perpetration or victimisation were found, but children with asthma were more likely to be bully/victims (involved both as target and perpetrator), compared to those without asthma. Children with asthma who were victims of bullying had greater peer problems and overall adjustment problems; bully/victims did not show this pattern. Children with asthma may be more likely to be bully/victims, and those who are victims of bullying may be at elevated risk for psychosocial adjustment problems and require particular support in this area from school counsellors and psychologists.
Treatment resistance causes significant burden in psychosis. Clozapine is the only evidence-based pharmacologic intervention available for people with treatment-resistant schizophrenia; current guidelines recommend commencement after two unsuccessful trials of standard antipsychotics.
Aims
This paper aims to explore the prevalence of treatment resistance and pathways to commencement of clozapine in UK early intervention in psychosis (EIP) services.
Method
Data were taken from the National Evaluation of the Development and Impact of Early Intervention Services study (N = 1027) and included demographics, medication history and psychosis symptoms measured by the Positive and Negative Syndrome Scale (PANSS) at baseline, 6 months and 12 months. Prescribing patterns and pathways to clozapine were examined. We adopted a strict criterion for treatment resistance, defined as persistent elevated positive symptoms (a PANSS positive score ≥16, equating to at least two items of at least moderate severity), across three time points.
Results
A total of 143 (18.1%) participants met the definition of treatment resistance of having continuous positive symptoms over 12 months, despite treatment in EIP services. Sixty-one (7.7%) participants were treatment resistant and eligible for clozapine, having had two trials of standard antipsychotics; however, only 25 (2.4%) were prescribed clozapine over the 12-month study period. Treatment-resistant participants were more likely to be prescribed additional antipsychotic medication and polypharmacy, instead of clozapine.
Conclusions
Prevalent treatment resistance was observed in UK EIP services, but prescription of polypharmacy was much more common than clozapine. Significant delays in the commencement of clozapine may reflect a missed opportunity to promote recovery in this critical period.
Anemia (and especially mild forms) is a frequent laboratory finding in the elderly and is usually regarded in our everyday practice in psychiatry as an incidental innocent finding.
However, the growing body of literature proves otherwise.
Recent literature shows that anemia in the elderly has serious negative impact on mortality, morbidity and quality of life in this age group.
Despite the importance of this topic in mental health care, there is paucity or even lack of studies aiming to examine the magnitude of this problem in psychiatric hospitals and to suggest potential solutions for it.
In this small study, we aim to examine the prevalence of anemia in an inpatient psychiatric hospital, the types of anemia found, the investigations done and if any treatment was given.
Design and methods
Inpatient case notes were examined retrospectively for patients admitted to the Julian hospital from June 2010 to December 2010.
Anemia was defined according to the WHO criteria1 as a hemoglobin concentration lower than 12 g/dL in women and 13 g/dL in men.
Results
Based on WHO criteria, most of our elderly patients were found to be anemic, with a significantly higher frequency in men than in women. The prevalence of anemia increased with increasing age, both in men and in women.
Conclusions
Anemia in elderly is a frequent, underappreciated and potentially morbid condition accounting for significant morbidity and mortality in this population.
As mental health professionals, we must work with our colleagues in medicine to translate awareness into action.
A late onset frontal lobe syndrome (LOF) refers to a clinical syndrome with apathy, disinhibition, or stereotypical behavior arising in middle or late adulthood. Diagnostics are challenging, and both clinicians and patients need reliable predictors of progression to improve clinical guidance. In this longitudinal multicenter and genetically screened prospective study, 137 LOF patients with frontal behavior (FBI score≥11) and/or stereotypical behavior (SRI≥10) were included. Progression was defined as institutionalization, death, or progression of frontal or temporal atrophy at magnetic resonance imaging (MRI) after two years of follow up. Absence of progression at MRI in addition to stable or improved Mini Mental State Examination and Frontal Assessment Battery scores after two years was indicative for non-progression. The presence of stereotypy and a neuropsychological profile with executive deficits at baseline were found to be predictive for progression, while a history and family history with psychiatric disorders were predictors for non-progression. The combination of these clinical markers had a predictive value of 80.4% (p < 0.05). In patients presenting with late onset behavioral symptoms, an appraisal of the rate of deterioration can be made by detailed mapping of clinical symptoms. Distinction of progressive discourses from non-progressive or treatable conditions is to be gained.
Social disability is a hallmark of severe mental illness yet individual differences and factors predicting outcome are largely unknown.
Aim
To explore trajectories and predictors of social recovery following a first episode of psychosis (FEP).
Method
A sample of 764 individuals with FEP were assessed on entry into early intervention in psychosis (EIP) services and followed up over 12 months. Social recovery profiles were examined using latent class growth analysis.
Results
Three types of social recovery profile were identified: Low Stable (66%), Moderate-Increasing (27%), and High-Decreasing (7%). Poor social recovery was predicted by male gender, ethnic minority status, younger age at onset of psychosis, increased negative symptoms, and poor premorbid adjustment.
Conclusions
Social disability is prevalent in FEP, although distinct recovery profiles are evident. Where social disability is present on entry into EIP services it can remain stable, highlighting a need for targeted intervention.
Early intervention services (EIS) comprise low-stigma, youth-friendly mental health teams for young people undergoing first-episode psychosis (FEP). Engaging with the family of the young person is central to EIS policy and practice.
Aims
By analysing carers' accounts of their daily lives and affective challenges during a relative's FEP against the background of wider research into EIS, this paper explores relationships between carers' experiences and EIS.
Method
Semi-structured longitudinal interviews with 80 carers of young people with FEP treated through English EIS.
Results
Our data suggest that EIS successfully aid carers to support their relatives, particularly through the provision of knowledge about psychosis and medications. However, paradoxical ramifications of these user-focused engagements also emerge; they risk leaving carers' emotions unacknowledged and compounding an existing lack of help-seeking.
Conclusions
By focusing on EIS's engagements with carers, this paper draws attention to an urgent broader question: as a continuing emphasis on care outside the clinic space places family members at the heart of the care of those with severe mental illness, we ask: who can, and should, support carers, and in what ways?
The effect of prenatal distress on the risk of a small for gestational age (SGA) infant is uncertain. We have addressed the influences of prenatal stress, anxiety and depression on the risk of SGA. We also examined the effects of infant sex and timing of distress during pregnancy on any observed associations.
Method
The study population comprised 5606 healthy nulliparous pregnant women who participated in the international prospective Screening for Obstetric and Pregnancy Endpoints (SCOPE) study. Women completed the Perceived Stress Scale (PSS), the short form of the Spielberger State–Trait Anxiety Inventory (STAI) and the Edinburgh Postnatal Depression Scale (EPDS) at 15 ± 1 and 20 ± 1 weeks' gestation. SGA was defined as birthweight below the 10th customized percentile. Logistic regression was used for data analysis, adjusting for several potential confounders such as maternal age, body mass index (BMI), smoking, socio-economic status and physical exercise.
Results
The risk of SGA was increased in relation to mild [adjusted odds ratio (aOR) 1.35, 95% confidence interval (CI) 1.07–1.71], moderate (aOR 1.26, 95% CI 1.06–1.49), high (aOR 1.45, 95% CI 1.08–1.95) and very high stress scores (aOR 1.56, 95% CI 1.03–2.37); very high anxiety score (aOR 1.45, 95% CI 1.13–1.86); and very high depression score (aOR 1.14, 95% CI 1.05–1.24) at 20 ± 1 weeks' gestation. Sensitivity analyses showed that very high anxiety and very high depression increases the risk of SGA in males but not in females whereas stress increases the risk of SGA in both males and females.
Conclusions
These findings suggest that prenatal stress, anxiety and depression measured at 20 weeks' gestation increase the risk of SGA. The effects of maternal anxiety and depression on SGA were strongest in male infants.
Interventions to reduce treatment delay in first-episode psychosis have met with mixed results. Systematic reviews highlight the need for greater understanding of delays within the care pathway if successful strategies are to be developed.
Aims
To document the care-pathway components of duration of untreated psychosis (DUP) and their link with delays in accessing specialised early intervention services (EIS). To model the likely impact on efforts to reduce DUP of targeted changes in the care pathway.
Method
Data for 343 individuals from the Birmingham, UK, lead site of the National EDEN cohort study were analysed.
Results
A third of the cohort had a DUP exceeding 6 months. The greatest contribution to DUP for the whole cohort came from delays within mental health services, followed by help-seeking delays. It was found that delay in reaching EIS was strongly correlated with longer DUP.
Conclusions
Community education and awareness campaigns to reduce DUP may be constrained by later delays within mental health services, especially access to EIS. Our methodology, based on analysis of care pathways, will have international application when devising strategies to reduce DUP.
The proposed title for this study, with due deference to Ann Williams, was ‘The English and the Norman Conquest – according to Wace’, but that implied yet another skirmish in the Hastings ancestry stakes or, perhaps, a Domesday database-style dot map of his inventive gazetteer of King Harold's towns and counties. However, the cultural re-orientation is intentional and, in the spirit of independent vernacular scholarship so well-represented by Wace (Magister was, surely, the equivalent of Doctor today), there is also a shift in time. His Roman de Rou is re-assessed as the source of an English prosopography for the twenty-year period between the accession of Stephen of Blois in 1135 and the first years of the reign of Henry II.
The purpose is to identify those of the so-called ‘Conqueror's Companions’ exclusive to Wace who occupy a no-man's land in surname history (albeit a vigorous virtual life). His work had been read as a tenurial mapping exercise but he was discredited – solely on the basis of the ‘1066’ section translated in 1837 – because so few of the personal or (presumed) locative names were found in the orthodox literature. Wace was the first to use the Anglo-Norman term surnons in what would now be considered a prosopographical context (lines 8659–60) and almost all of them correspond with twelfth-century hereditary English family names. This is more than a co-incidence of adopted feudal identifications: his neighbourhood contemporaries, either from choice or service obligation, were becoming ‘Domesday Descendants’.
The administration of the forensic science process falls into the hands of supervisors, local administrators, and prosecution attorneys and police agencies. In the current structure, the police and prosecution are the principal and the forensic scientists the agent. I identify changes that must be made in that relationship to eliminate biases and to determine the major obstacles that stand in the way of creating the necessary changes. I focus on the ‘middle managers’ – the supervisors and laboratory directors – as the cultural key masters. I recommend: mechanism design principles to enable laboratories to report to a board of directors, rather than the prosecutor and police; for the development of compensation plans for middle managers to build a culture of learning based on error tolerance rather than error punishment; and for the use of intrinsic and extrinsic motivations to facilitate the identity changes of cultural key masters.
First published in French in Philadelphia in 1797 and translated into English for the London edition of 1798 reissued here, this travelogue by André Everard van Braam Houckgeest (1739–1801) was received with enthusiasm by readers hungry for exotic accounts of distant lands. It vividly describes a visit to the Chinese imperial court by a delegation from the Dutch East India Company soon after the British Macartney embassy, and delivers a rare glimpse of an unfamiliar landscape and culture. Fascinated by his experiences en route from Canton to Beijing and at the Summer Palace, van Braam records that he thought it 'far better to lose a few hours rest, than to let a single remarkable object escape me'. Volume 1 follows the expedition's journey from Canton to Uoitime, and includes notes on special terms and important cultural concepts, a 'correct chart' of the route taken and a full itinerary.

The monogenean Protopolystoma xenopodis has been established in Wales for >40 years following introduction with Xenopus laevis from South Africa. This provides an experimental system for determining constraints affecting introduced species in novel environments. Parasite development post-infection was followed at 15, 20 and 25°C for 15 weeks and at 10°C for ⩾1 year and correlated with temperatures recorded in Wales. Development was slowed/arrested at ⩽10°C which reflects habitat conditions for >6 months/year. There was wide variation in growth at constant temperature (body size differing by >10 times) potentially attributable in part to genotype-specific host-parasite interactions. Parasite density had no effect on size but host sex did: worms in males were 1·8 times larger than in females. Minimum time to patency was 51 days at 25°C and 73 days at 20°C although some infections were still not patent at both temperatures by 105 days p.i. In Wales, fastest developing infections may mature within one summer (about 12 weeks), possibly accelerated by movements of hosts into warmer surface waters. Otherwise, development slows/stops in October–April, delaying patency to about 1 year p.i., while wide variation in developmental rates may impose delays of 2 years in some primary infections and even longer in secondary infections.
Factors affecting survival of parasites introduced to new geographical regions include changes in environmental temperature. Protopolystoma xenopodis is a monogenean introduced with the amphibian Xenopus laevis from South Africa to Wales (probably in the 1960s) where low water temperatures impose major constraints on life-cycle processes. Effects were quantified by maintenance of eggs from infections in Wales under controlled conditions at 10, 12, 15, 18, 20 and 25°C. The threshold for egg viability/ development was 15°C. Mean times to hatching were 22 days at 25°C, 32 days at 20°C, extending to 66 days at 15°C. Field temperature records provided calibration of transmission schedules. Although egg production continues year-round, all eggs produced during >8 months/ year die without hatching. Output contributing significantly to transmission is restricted to 10 weeks (May–mid-July). Host infection, beginning after a time lag of 8 weeks for egg development, is also restricted to 10 weeks (July–September). Habitat temperatures (mean 15·5°C in summer 2008) allow only a narrow margin for life-cycle progress: even small temperature increases, predicted with ‘global warming’, enhance infection. This system provides empirical data on the metrics of transmission permitting long-term persistence of isolated parasite populations in limiting environments.
The rule of the Angevins in Brittany is characterized usually as opening an isolated 'Celtic' society to a wider world and imposing new and alien institutions. This study of Brittany under the Angevins, first published in 2000, demonstrates that the opposite is true: that before the advent of Henry II in 1158, the Bretons were already active participants in Anglo-Norman and French society. Indeed those Bretons with landholdings in England, Normandy and Anjou were already accustomed to Angevin rule. The book examines in detail the means by which Henry II gained sovereignty over Brittany and how it was governed subsequently by the Angevin kings of England from 1158 to 1203. In particular, it examines the extent to which the Angevins ruled Brittany directly, or delegated authority either to native dukes or royal ministers and shows that in this respect the nature of Angevin rule changed and evolved over the period.
The possibility of micro-epidemics of severe leptospirosis occurring on the island of Barbados was investigated by examining the space-time clustering of the disease in 212 laboratory-confirmed cases admitted to Queen Elizabeth Hospital, Bridgetown, over a 7-year period. A series of 109 patients with symptoms compatible with leptospirosis but shown to be otherwise by laboratory examination were also examined for comparison. No significant space-time clustering was found among the leptospirosis cases, indicating no evidence for micro-epidemics. By comparison, statistically significant clustering was apparent among the smaller non-leptospirosis series. Possible explanations for the absence of observed micro-epidemics of leptospirosis are discussed.
A serological survey for leptospiral agglutinins was undertaken between 1980 and 1983 in over 500 Barbadian and 500 Trinidadian school-children aged 7–14 years. The children were selected randomly from urban and rural schools, and examined three times at approximately annual intervals. A total of 12·5% of the Barbadian children and 9·5% of the Trinidadian children were seropositive at a titre of 50 using the microscopic agglutination test. On both islands, seroprevalence was higher in males than females, the difference being significant in rural schools. There was no evidence of a difference in prevalence between urban and rural schools, or between junior and secondary age-ranges. Analysis of the association of serology with socio-economic and behavioural factors showed a significant association in Trinidad with father's occupation, but most other variables on both islands showed only weak non-significant associations. Fourteen children in Trinidad and three in Barbados seroconverted. Seroconversion in Trinidad occurred at a rate of 1·6% per annum and was significantly associated with livestock contact and with absence of a tapped water supply. In Trinidad, Autumnalis was the most commonly recorded serogroup, but this accounted for less than a quarter of seropositives. In Barbados, Panama accounted for over half the seropositives and was about four times more common than the next most common serogroup, Autumnalis. In Barbados, 39 persons aged 19 or less were hospitalized with leptospirosis between November 1979 and December 1986. Average annual incidence rates were 2·2, 4·9 and 13·3 per 100000 in the 5·9, 10·14 and 15·19 age-groups, respectively.
