Re-description of Dysponetus joeli Olivier et al., 2012 (Polychaeta, Chrysopetalidae), with a new key to species of the genus
Teresa Darbyshire
European Journal of Taxonomy , 2012, DOI: 10.5852/ejt.2012.27
Abstract: Dysponetus is a genus of the family Chrysopetalidae with twelve currently described species. Specimens are fragile and easily damaged or broken during sampling making identification difficult. The most recently described species, Dysponetus joeli Olivier et al., 2012, from the Bay of Biscay and English Channel, was described from a few small, damaged and poorly preserved specimens. New specimens from the Isles of Scilly, in much better condition, resembled D. joeli except for the absence of ventral cirri on segment 3. Examination of the type material of D. joeli showed it to be identical to these new specimens and highlighted errors in the original description of the species. This paper corrects the errors and a revised key to species is produced. The differences between D. joeli and the two most similar species, D. bipapillatus Dahlgren, 1996 and D. macroculatus Dahlgren, 1996 are also detailed.
Nursing heroism in the 21st Century'
Philip Darbyshire
BMC Nursing , 2011, DOI: 10.1186/1472-6955-10-4
Abstract: Is heroism a legitimate part of nursing, or are nurses simply 'just doing their job' even when facing extreme personal danger? In this paper I explore the place and relevance of heroism in contemporary nursing. I propose that nursing heroism deserves a broader appreciation and that within the term lie many hidden, 'unsung' or 'unrecorded' heroisms. I also challenge the critiques of heroism that would condemn it as part of a 'militarisation' of nursing. Finally, I argue that nursing needs to be more open in celebrating our heroes and the transformative power of nursing achievements.The language of heroism may sound quaint by 21st Century standards but nursing heroism is alive and well in the best of our contemporary nursing ethos and practice.Any author addressing the topic of "Nursing Heroics: what it means in the 21st Century" faces a challenge and even more so when they take this on as the Vivian Bullwinkel Memorial Lecture.They are perhaps doomed before they begin, for what modern day nursing heroism outside of a war zone is ever going to be able to withstand comparison with the experiences of Sister Bullwinkel and her colleagues - during the fall of Singapore, the sinking of the Vyner Brooke, the murderous machine gunning of Vivian and her 21 fellow nurses on Radji Beach and her years of internment in the death camps of Sumatra.[1-3]Somehow, to mention any other forms of heroism in the same breath seems almost disrespectful, a feat of linguistic relativism designed to dilute or trivialize the power of the term. But please, bear with me as I explore the idea and the practices of nursing heroism in our current age.First, the more traditional concept of heroism as courage and providing service to others in the face of extreme personal danger is undoubtedly alive and well in nursing and in other human services. Firemen still enter burning buildings to save their occupants and nurses still join their health care colleagues in providing care to the hungry, the fearful

Death by acid rain: VAP or EXIT?
Kentigern Thorburn, Andrew Darbyshire
Critical Care , 2009, DOI: 10.1186/cc8169
Abstract: Ventilator-associated pneumonia (VAP) is defined as a new (nosocomial) lower respiratory tract infection diagnosed in mechanically ventilated patients ≥48 hours ('early-onset' VAP) or ≥4 days ('late-onset' VAP) after intubation [1-5]. Management of early-onset and late-onset VAP may differ as the causative factors and likely pathogens will influence treatment strategies, such as antimicrobial therapy [2,3,5]. VAP is associated with increased mortality and morbidity, prolonged duration of ventilation and hospital stay, and escalated costs of hospitalisation [2,3,5-9]. In resource-rich countries VAP is reported to be the second most common nosocomial/hospital-acquired infection in pediatric and neonatal intensive care units, with incidences ranging from 3 to 30% and VAP-attributable mortality rates up to 20% [5,7,9]. The potential devastating impact of VAP is emphasized by the study of Abdel Gawad and colleagues [1] where a 50% incidence of VAP and 70% mortality with VAP means that more than 80% of all the deaths in their unit were due to hospital-acquired infection/VAP.Defining VAP is the easy aspect, making the correct diagnosis (let alone confirmation) becomes more challenging, and establishing universally accepted criteria is a distant goal. There is no gold standard. The Clinical Pulmonary Infection Score (CPIS), utilized in the study by Abdel Gawad and colleagues, is based on five clinical parameters - fever, leucocytosis, purulence of secretions, oxygenation, extent of radiographic infiltrates - and strengthened by cultures from the lower respiratory tract (most often broncho-alveolar lavage (BAL)) [10]. It suffers from poor inter-rater agreement and retrograde influence from positive BAL results [11]. The current reference standard (read 'gold standard') comprises the clinical criteria for the diagnosis of VAP established by the National Nosocomial Infection Surveillance (NNIS) system of the Centers for Disease Control and Prevention (CDC), which incorporate a
Prognostic and Survival Factors in Myxofibrosarcomas

Sarcoma , 2012, DOI: 10.1155/2012/830879
Abstract: Aim. Our study aimed to determine prognostic factors for survival and recurrence in myxofibrosarcomas based on the experience of a single institution. Methods. Patients who had been diagnosed with a myxofibrosarcoma were identified from our database. Survival and recurrence were evaluated with Kaplan Meier survival curves for univariate and cox regression for multivariate analysis. Results. 174 patients with a diagnosis of myxofibrosarcoma were identified. Two patients were excluded due to incomplete information, leaving 172 patients with a mean age of 67 years. Surgery was undertaken in all but 6 patients. Five-year survival was better for myxofibrosarcomas when compared to other soft tissue sarcomas (63% versus 57%). Size, grade of tumour, age, and metastases were all found to be prognostic factors. Local recurrence occurred in 29 patients (17%) with an overall risk of 15% at 5 years. Previous inadvertent excision significantly raised this risk to 45%. Wide surgical margins and depth of tumour, however, had no impact on recurrence. Conclusion. Factors previously identified as prognostic did not demonstrate such a relationship in our study, highlighting the unpredictable nature of myxofibrosarcomas. Future treatment may lie in developing an understanding molecular basis of the tumour and directing therapies accordingly.

"There's nothing I can't do – I just put my mind to anything and I can do it": a qualitative analysis of how children with chronic disease and their parents account for and manage physical activity

BMC Pediatrics , 2009, DOI: 10.1186/1471-2431-9-1
Abstract: Multiple qualitative data collection techniques were used to elicit the children and young people's perspectives and experiences of physical activity, including focus groups, maps, photos and 'traffic light posters'. The children's parents were interviewed separately to ascertain their views of their child's participation in physical activities.Children and young people described their active participation in a wide variety of physical activities including organised sports and play, but made very little mention of any negative influence or impact due to their disease. Their parents' stories described the diligent background planning and management undertaken to enable their child to participate in a wide range of physical activities.The results of this study suggest that for these children and young people, having a chronic disease was not perceived as a barrier to participation in organised sport and recreational activities. They were physically active and perceived themselves to be no different from their peers. Their positive beliefs were shared by their parents and the level of participation described was enabled by the high level of parental support and background planning involved in managing their child's health care needs.Physical inactivity is a growing international child health concern [1], considered to be one of the most important risk factors for significant adult morbidity and mortality [2]. It is argued that being physically active is important for children's overall physical, emotional and social health and wellbeing and that it is a positive benefit that extends into adult life [3,4].Children are neither a homogenous nor a universally healthy population. In Australia the prevalence of asthma has been reported as 24.8% of 0–17 year olds [5], the prevalence of type 1 diabetes among 0–14 year olds as 19.2/100,000 in boys and 18.6/100,000 in girls, and the prevalence of cystic fibrosis as 40 per 100,000 [6]. The care of children with chronic diseases c

Limitations of poster presentations reporting educational innovations at a major international medical education conference
Morris Gordon,Daniel Darbyshire,Aamir Saifuddin,Kavitha Vimalesvaran
Medical Education Online , 2013, DOI: 10.3402/meo.v18i0.20498
Abstract: Background: In most areas of medical research, the label of ‘quality’ is associated with well-accepted standards. Whilst its interpretation in the field of medical education is contentious, there is agreement on the key elements required when reporting novel teaching strategies. We set out to assess if these features had been fulfilled by poster presentations at a major international medical education conference. Methods: Such posters were analysed in four key areas: reporting of theoretical underpinning, explanation of instructional design methods, descriptions of the resources needed for introduction, and the offering of materials to support dissemination. Results: Three hundred and twelve posters were reviewed with 170 suitable for analysis. Forty-one percent described their methods of instruction or innovation design. Thirty-three percent gave details of equipment, and 29% of studies described resources that may be required for delivering such an intervention. Further resources to support dissemination of their innovation were offered by 36%. Twenty-three percent described the theoretical underpinning or conceptual frameworks upon which their work was based. Conclusions: These findings suggest that posters presenting educational innovation are currently limited in what they offer to educators. Presenters should seek to enhance their reporting of these crucial aspects by employing existing published guidance, and organising committees may wish to consider explicitly requesting such information at the time of initial submission.
Origin of African Physacanthus (Acanthaceae) via Wide Hybridization

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0055677
Abstract: Gene flow between closely related species is a frequent phenomenon that is known to play important roles in organismal evolution. Less clear, however, is the importance of hybridization between distant relatives. We present molecular and morphological evidence that support origin of the plant genus Physacanthus via “wide hybridization” between members of two distantly related lineages in the large family Acanthaceae. These two lineages are well characterized by very different morphologies yet, remarkably, Physacanthus shares features of both. Chloroplast sequences from six loci indicate that all three species of Physacanthus contain haplotypes from both lineages, suggesting that heteroplasmy likely predated speciation in the genus. Although heteroplasmy is thought to be unstable and thus transient, multiple haplotypes have been maintained through time in Physacanthus. The most likely scenario to explain these data is that Physacanthus originated via an ancient hybridization event that involved phylogenetically distant parents. This wide hybridization has resulted in the establishment of an independently evolving clade of flowering plants.
