Stroke Survivors Who Score below Threshold on Standard Depression Measures May Still Have Negative Cognitions of Concern
Background and Purpose— There has been an increase in screening for depression in the physically ill. We explored whether important negative cognitions may be missed by conventional approaches to screening for depression in 2 independently conducted stroke studies with similar methods.
Methods— The Auckland Regional Community Stroke (ARCOS) study was a prospective, population-based stroke incidence study conducted in Auckland, New Zealand, for 12 months in 2002 to 2003. The Stroke Outcomes Study was a prospective, hospital cohort study conducted in Leeds and Bradford, United Kingdom, for 33 months in 2002 to 2005. Symptoms of abnormal mood were assessed at 6 months in ARCOS with a single simple question, “Do you often feel sad and depressed?” and the 28-item General Health Questionnaire administered as part of a structured interview and in the Stroke Outcomes Study with the 28-item General Health Questionnaire and a single question about depressed mood taken from the Present State Examination.
Results— Mood data were available at 6 months from 770 ARCOS and 492 Stroke Outcomes Study participants. A significant proportion (up to 28%) of people who did not meet study criteria for depression reported important negative cognitions such as hopelessness, worthlessness, or suicidality. People who were older, dependent in activities of daily living, or not partnered were more likely to report negative cognitions.
Conclusions— Important negative cognitions, including suicidal thoughts, may be missed when people are screened for depression after stroke. Screening alone is not an adequate substitute for a sensitive exploration of the psychological impact of stroke on the survivor
Examining the cognitive profile of children with Developmental Coordination Disorder
Background:
While primarily a motor disorder, research considering the cognitive abilities in children with Developmental Coordination Disorder (DCD) is limited; even though these children often struggle academically.
Aims:
The present study aimed to characterise the IQ profile of children with and without DCD, and to identify whether children with DCD exhibit specific cognitive weaknesses.
Methods and procedures:
104 children participated in the study. Fifty-two children (mean age, 9 years) with a diagnosis of DCD were matched to 52 typically-developing children by age and gender. Cognitive ability was assessed using the Wechsler Intelligence Scale for Children (WISC-IV).
Outcomes and results:
Children with DCD performed poorer than their peers on processing speed and working memory measures. Individual analyses revealed varied performance in the DCD group across all cognitive indices, despite displaying Full-Scale IQs in the typical range. Discriminant function analyses show processing speed and working memory performance predicted only 23% of between-group variability.
Conclusions:
Children with DCD present with a heterogeneous cognitive profile, lending support to individual case analyses in research and when designing educational assistance plans. The motorically-demanding nature of the WISC-IV processing speed tasks raises specific concerns about using this index of the IQ assessment in this population. Research and practical implications are raised
Safety culture and the 5 steps to safer surgery: an intervention study.
BACKGROUND: Improvements in safety culture have been postulated as one of the mechanisms underlying the association between the introduction of the World Health Organisation (WHO) Surgical Safety Checklist with perioperative briefings and debriefings, and enhanced patient outcomes. The 5 Steps to Safer Surgery (5SSS) incorporates pre-list briefings, the three steps of the WHO Surgical Safety Checklist (SSC) and post-list debriefings in one framework. We aimed to identify any changes in safety culture associated with the introduction of the 5SSS in orthopaedic operating theatres. METHODS: We assessed the safety culture in the elective orthopaedic theatres of a large UK teaching hospital before and after introduction of the 5SSS using a modified version of the Safety Attitude Questionnaire - Operating Room (SAQ-OR). Primary outcome measures were pre-post intervention changes in the six safety culture domains of the SAQ-OR. We also analysed changes in responses to two items regarding perioperative briefings. RESULTS: The SAQ-OR survey response rate was 80% (60/75) at baseline and 74% (53/72) one yr later. There were significant improvements in both the reported frequency (P<0.001) and perceived importance (P=0.018) of briefings, and in five of the six safety culture domain scores (Working Conditions, Perceptions of Management, Job Satisfaction, Safety Climate and Teamwork Climate) of the SAQ-OR (P<0.001 in all cases). Scores in the sixth domain (Stress Recognition) decreased significantly (P=0.028). CONCLUSIONS: Implementation of the 5SSS was associated with a significant improvement in the safety culture of elective orthopaedic operating theatres
Dramatizing an Articulation of the (P)Artistic Researcher’s Posthumanist Pathway to a ‘Slow Professorship’ Within the Corporate University Complex
Within academia, the practical arts researcher endures an unstable status owing, in part, to the diverse research methodologies gathered underneath the umbrellas of Practice-[led/based/as/for]- Research. (P)Artistic Research is difficult to define, no less validate, in a result-oriented, data-driven, ‘performance’-measuring culture. The (P)Artistic Researcher embodies dissent in such contexts, as the nature of most artistic research is process-oriented, collaborative and solution-finding. In response to Berg and Seeber’s pleas for ‘slowness’ in The Slow Professor, this chapter reflects critically on the author’s habits and history as a (P)Artistic Researcher while moving through a ‘gap’ in employment, from a dramatic resignation at one institution to an acceptance of a new post at another institution, one year later. This writing is contaminated by aspects of the author’s ‘playwrighting’ practice, becoming a posthuman ‘playper’ in which forms of writing are intertwined, and structure, layout and grammatical positioning are used innovatively to produce new knowledge which is not ‘in-prism-ed’ by the narrow perspective of the corporate university. The content of the ‘playper’ offers a malleable frame with several pedagogical points of entry, including prompts, provocations and practical exercises which intend to slowly contaminate the classroom with a conscientious commitment to a posthuman understanding of the world

Treatment of bone loss in proximal femurs of postmenopausal osteoporotic women with AGN1 local osteo-enhancement procedure (LOEP) increases hip bone mineral density and hip strength: a long-term prospective cohort study.
This first-in-human study of AGN1 LOEP demonstrated that this minimally-invasive treatment durably increased aBMD in femurs of osteoporotic postmenopausal women. AGN1 resorption was coupled with new bone formation by 12 weeks and that new bone was maintained for at least 5-7 years resulting in substantially increased FEA-estimated femoral strength.IntroductionThis first-in-human study evaluated feasibility, safety, and in vivo response to treating proximal femurs of postmenopausal osteoporotic women with a minimally-invasive local osteo-enhancement procedure (LOEP) to inject a resorbable triphasic osteoconductive implant material (AGN1).MethodsThis prospective cohort study enrolled 12 postmenopausal osteoporotic (femoral neck T-score ≤ - 2.5) women aged 56 to 89 years. AGN1 LOEP was performed on left femurs; right femurs were untreated controls. Subjects were followed-up for 5-7 years. Outcomes included adverse events, proximal femur areal bone mineral density (aBMD), AGN1 resorption, and replacement with bone by X-ray and CT, and finite element analysis (FEA) estimated hip strength.ResultsBaseline treated and control femoral neck aBMD was equivalent. Treated femoral neck aBMD increased by 68 ± 22%, 59 ± 24%, and 58 ± 27% over control at 12 and 24 weeks and 5-7 years, respectively (p < 0.001, all time points). Using conservative assumptions, FEA-estimated femoral strength increased by 41%, 37%, and 22% at 12 and 24 weeks and 5-7 years, respectively (p < 0.01, all time points). Qualitative analysis of X-ray and CT scans demonstrated that AGN1 resorption and replacement with bone was nearly complete by 24 weeks. By 5-7 years, AGN1 appeared to be fully resorbed and replaced with bone integrated with surrounding trabecular and cortical bone. No procedure- or device-related serious adverse events (SAEs) occurred.ConclusionsTreating femurs of postmenopausal osteoporotic women with AGN1 LOEP results in a rapid, durable increase in aBMD and femoral strength. These results support the use and further clinical study of this approach in osteoporotic patients at high risk of hip fracture
Impaired perception of facial motion in autism spectrum disorder

This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.This article has been made available through the Brunel Open Access Publishing Fund.Facial motion is a special type of biological motion that transmits cues for socio-emotional communication and enables the discrimination of properties such as gender and identity. We used animated average faces to examine the ability of adults with autism spectrum disorders (ASD) to perceive facial motion. Participants completed increasingly difficult tasks involving the discrimination of (1) sequences of facial motion, (2) the identity of individuals based on their facial motion and (3) the gender of individuals. Stimuli were presented in both upright and upside-down orientations to test for the difference in inversion effects often found when comparing ASD with controls in face perception. The ASD group’s performance was impaired relative to the control group in all three tasks and unlike the control group, the individuals with ASD failed to show an inversion effect. These results point to a deficit in facial biological motion processing in people with autism, which we suggest is linked to deficits in lower level motion processing we have previously reported
Comparison of Group-based Outpatient Physiotherapy With Usual Care After Total Knee Replacement: a Feasibility Study For a Randomized Controlled Trial
Objective: To evaluate the feasibility of conducting a randomized controlled trial comparing group-based outpatient physiotherapy with usual care in patients following total knee replacement.
Design: A feasibility study for a randomized controlled trial.
Setting: One secondary-care hospital orthopaedic centre, Bristol, UK.
Participants: A total of 46 participants undergoing primary total knee replacement.
Interventions: The intervention group were offered six group-based exercise sessions after surgery. The usual care group received standard postoperative care. Participants were not blinded to group allocation.
Outcome measures: Feasibility was assessed by recruitment, reasons for non-participation, attendance, and completion rates of study questionnaires that included the Lower Extremity Functional Scale and Knee Injury and Osteoarthritis Outcome Score.
Results: Recruitment rate was 37%. Five patients withdrew or were no longer eligible to participate. Intervention attendance was high (73%) and 84% of group participants reported they were ‘very satisfied’ with the exercises. Return of study questionnaires at six months was lower in the usual care (75%) than in the intervention group (100%). Mean (standard deviation) Lower Extremity Functional Scale scores at six months were 45.0 (20.8) in the usual care and 57.8 (15.2) in the intervention groups.
Conclusion: Recruitment and retention of participants in this feasibility study was good. Group-based physiotherapy was acceptable to participants. Questionnaire return rates were lower in the usual care group, but might be enhanced by telephone follow-up. The Lower Extremity Functional Scale had high responsiveness and completion rates. Using this outcome measure, 256 participants would be required in
a full-scale randomized controlled trial
<i>Albugo candida</i> race diversity, ploidy and host-associated microbes revealed using DNA sequence capture on diseased plants in the field
• Physiological races of the oomycete Albugo candida are biotrophic pathogens of diverse plant species, primarily the Brassicaceae, and cause infections that suppress host immunity to other pathogens. However, A. candida race diversity and the consequences of host immunosuppression are poorly understood in the field. • We report a method that enables sequencing of DNA of plant pathogens and plant-associated microbes directly from field samples (Pathogen Enrichment Sequencing: PenSeq). We apply this method to explore race diversity in A. candida and to detect A. candida-associated microbes in the field (91 A. candida-infected plants).• We show with unprecedented resolution that each host plant species supports colonization by one of 17 distinct phylogenetic lineages, each with an unique repertoire of effector candidate alleles. These data reveal the crucial role of sexual and asexual reproduction, polyploidy and host domestication in A. candida specialization on distinct plant species. Our bait design also enabled phylogenetic assignment of DNA sequences from bacteria and fungi from plants in the field.• This paper shows that targeted sequencing has a great potential for the study of pathogen populations while they are colonizing their hosts. This method could be applied to other microbes, especially to those that cannot be cultured
