Published: January 2018

Objective. We aimed to assess the usefulness of the Salzburg Consensus Criteria (SCC) for determining the prognosis of critically ill patients with nonconvulsive status epilepticus (NCSE). Methods. We retrospectively reviewed consecutive patients with unconsciousness followed up in the intensive care unit (ICU). Three clinical neurophysiologists, one of them blinded to clinical and laboratory data, reevaluated all EEG data independently and determined NCSE according to SCC. The incidence of NCSE and ictal EEG patterns and their relationship to clinical, laboratory, neuroradiological, and prognostic findings were assessed. Results. A total of 107 consecutive patients with mean age 68.2 ± 15.3 years (57 females) were enrolled in the study. Primary neuronal injury was detected in 59 patients (55.7%). Thirty-three patients (30.8%) were diagnosed as NCSE. While authors decided to treat 33 patients (30.8%), 32 patients (29.9%) had been treated in real-life evaluation. Clinical and EEG improvement were detected in 12 patients (11.3%) in real-life treatment group showing correlation with lack of intubation and ICU stay related to postsurgical event. Rate of mortality (45.8%) was high showing association with systemic-metabolic etiology, severity of coma and presence of “plus” modifiers in the EEG. Conclusion and Significance. Our findings suggest that SCC is highly compatible with clinical practice in the decision for treatment of patients with NCSE. The presence of “plus” modifiers in the EEG was found to be associated with mortality in these patients and was a significant marker for the high mortality rate.
When Data Use Devolves Into Deficit Talk: Creating the Conditions for Productive Teacher Collaboration Using Data
Authors: Miranda Chandler P. , Jaffe-Walter Reva
Published: January 2018

Drawing on ethnographic research from a small urban high school serving predominantly low-income students in a large northeastern city, this case explores how a school leader seeks to improve the school’s graduation rates by analyzing student data. It asks readers to consider the overall organization of the meeting, the role of the principal, the positioning of teachers, and the resulting conversations about students that the meeting generates. The case suggests that data analysis is not a silver bullet for improvement and considers that organizational, cultural, and contextual elements need to be in place for teachers to effectively improve their practice and student outcomes.
Dual Antegrade Intramedullary Headless Screw Fixation for Treatment of Unstable Proximal Phalanx Fractures
Authors: Gaspar Michael P. , Gandhi Shiv D. , Culp Randall W. , Kane Patrick M.
Published: January 2018

Background: Although intramedullary headless screw (IMHS) fixation is a promising minimally invasive surgical treatment option for unstable proximal phalanx fractures, a single IMHS may provide inadequate fixation for certain fracture patterns. The purpose of this study was to evaluate the short-term clinical outcomes in a pilot series of patients with proximal phalanx fractures treated with dual antegrade IMHS fixation. Methods: We performed a retrospective chart review of proximal phalanx fractures treated with dual antegrade IMHS fixation with a minimum 1 year of follow-up. Demographic information including patient age, sex, occupation, workers’ compensation status, mechanism of injury, hand dominance, and injured digit were obtained. Postoperative outcomes measured included range of motion, grip strength, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) outcome scores, return to full-duty work interval, and complications. Results: Ten fractures in 10 patients (4 male, 6 female) satisfied study inclusion. The mean age of patients was 39 years (range, 20-62), and average follow-up duration was 84 weeks (range, 61-106). Final postoperative total active motion was 258° (range, 245°-270°), mean grip strength was 97% (range, 84%-104%) of the uninjured side, and QuickDASH score was 3.9 (range, 0-13.6). No complications occurred, and no patients required additional intervention. Conclusions: Dual antegrade IMHS fixation of proximal phalanx fractures resulted in excellent postoperative motion, near-normal grip strength, positive self-reported patient outcomes, and no complications with follow-up of at least 1 year. Further study in a larger number of patients is warranted to determine if this promising technique is superior to other modes of fixation.

Published: January 2018

Purpose: The purpose of this study was to report trends, complications, and costs associated with endoscopic carpal tunnel release (ECTR) and open carpal tunnel release (OCTR). Methods: Using Current Procedural Terminology (CPT) and International Classification of Diseases, Ninth Revision (ICD-9) codes, patients who had open versus endoscopic carpal tunnel release (CTR) were identified retrospectively in the PearlDiver database from both the Medicare and Humana (a private payer health insurance) populations from 2005 to 2014. These groups were then evaluated for postoperative complications, including wound infection within 90 days, wound dehiscence within 90 days, and intraoperative median nerve injury. We also used the data output for each group to compare the cost of the 2 procedure types. Data were analyzed via the Student t test. Statistical significance was set at P < .05. Results: A significantly lower percentage of patients in the endoscopic CTR group had a postoperative infection (5.21 vs 7.97 per 1000 patients per year, P < .001; 7.36 vs 11.23 per 1000 patients per year, P < .001) and wound dehiscence (1.58 vs 2.87 per 1000 patients per year, P < .001; 2.14 vs 3.73 per 1000 patients per year, P < .05) than open CTR group in the Medicare and Humana populations, respectively. Median nerve injury occurred 0.59/1000 ECTRs versus 1.69/1000 OCTRs (Medicare) and 1.96/1000 ECTRs versus 3.72/1000 OCTRs (Humana). Endoscopic CTR cost was more than open CTR for both the Medicare population ($1643 vs $1015 per procedure, P < .001) and Humana population ($1928 vs $1191 per procedure, P < .001). Conclusions: In both the Medicare and private insurance patient populations, endoscopic CTR is associated with fewer postoperative complications than open CTR, but is associated with greater expenses.

Published: January 2018

While exploring complex environments, conventional mobile robots can overcome obstacles of limited height and jumping robots can overcome obstacles several times their own size. When jumping motion and wheeled or tracked motion are combined to form a composite motion, robots have even better ability to traverse rugged terrain. Therefore, we designed a wheeled hopping robot with a novel combustion-powered actuator and carried out structural design and experimental studies. The combustion-powered actuator has a unique inlet scheme and good sealing performance and is easy to install. The jump height equation was obtained by analyzing the combustion process. With the help of orthogonal array design methods, the factors that affect the wheeled hopping robot’s jumping height were analyzed to improve its key design parameters and optimize its jumping performance. Finally, experiments were performed with the actuator and the wheeled hopping robot. When the stoichiometric ratio of the mixed fuels nears complete combustion, the combustion-powered actuator can jump 7.5 m high with a payload of 3.75 kg and its own weight of 1.25 kg, and the wheeled hopping robot can jump 4.5 m high with a payload of 6 kg. Evaluating the robot’s performance in terms of energy efficiency reveals that it has a significant jumping advantage.
How Does an Aesthetic Object Happen? Emergence, Disappearance, Multiplicity
Authors: Kobyshcha Varvara
Published: January 2018

In studying visual and plastic arts, social researchers tend to assume that an aesthetic object is pre-given to a viewer who does not participate in the process of the object’s becoming. They problematise the aesthetic status of an artwork, but not its objectness. This article shows that audience perception, considered as interaction and situated practice, does not merely define the meanings and emotions attached to a certain object, but plays a constitutive role in the object’s physical state and its very existence as an object, i.e. as an integrated unity extracted from its surroundings and affording a direct, intensive encounter. Synthesising the conceptual resources of Hennion’s pragmatics of taste, Simmel’s aesthetic theory, gestalt theory, and social phenomenology, I explain various ways an object in the situation of perception happens and achieves a certain mode of existence or fails to happen and disappears. The article is based on three empirical examples derived from the ethnographic study of the open-air land art/architectural festival ‘Archstoyanie’. The first case illustrates how an object is extracted from the environment and the festival’s infrastructure; the second, how the visitors destroy the incomplete boundaries of an object so that it dissolves into the surroundings; and the third, how an object maintains its integrity despite its inner complexity and multiple centres that attract the visitor’s attention.

Provision of Care for Patients Mechanical Ventilation in the Pacu
Authors: Hodge Stephen
Published: January 2018

The mechanical ventilation of patients within postanaesthetic care units (PACUs) is a practice that clinicians have experienced and assisted with for several years. The author's own clinical area, a PACU serving a large theatre suite, has recently seen provisions put in place to cater specifically for critically ill patients who require mechanical ventilation. The majority of patients requiring intervention are those that are in the immediate postoperative stage of their care, however patients from all wards and departments within the Trust, as well as those admitted through the accident and emergency department, are also accepted.
Developing a New Perioperative Organisation in Papua New Guinea
Authors: Woodhead Kate
Published: January 2018

A request to the International Federation of Perioperative Nurses (IFPN), by some nurses in Papua New Guinea led to Kate Woodhead and Phyllis Davis running a workshop in Port Moresby, Papua New Guinea. They set out to help the perioperative nurses establish their own organisation to advise the government on policy which affected their service, and to serve as a forum for perioperative education and motivation. This article describes the process, the enthusiasm which greeted them and the mechanisms by which the Papua New Guinea Perioperative Nurses Association came into being.
Ensuring Safe and Effective Practice: Fitness for Practice at the Point of Registration

Published: January 2018

The Nursing and Midwifery Council (NMC) has been reviewing its standards for the preparation of teachers and considering issues related to fitness for practice at the point of registration. This has resulted in new standards to support learning and assessment in practice (NMC 2006a). The standards have attempted to address learning in an interprofessional practice environment, taking account of the different professionals involved in supporting and assessing learning, while maintaining the integrity of particular professions.

Published: January 2018

Irrigating fluids are commonly used in endoscopic urological surgery. Recent studies have shown a benefit in using irrigant fluids warmed to body temperature to prevent the undesirable effects of cooling, including impaired coagulation function, reduced levels of drug clearance and shivering resulting in increase in oxygen requirements causing potential myocardial ischaemia.
Minimally Invasive Surgery of the Knee
Authors: Schindler Oliver S
Published: January 2018

Minimally invasive knee replacement surgery has been developed in an attempt to lessen the impact of operations on the patient's quality of life, in the same way as arthroscopy, the forefather of minimally invasive surgery (MIS), revolutionised cartilage and ligament surgery three decades earlier. The technique is based on minimising soft tissue and muscle trauma, skin incision length, and capsular disruption while trying to maintain the ultimate goal of a well-aligned, well-fixed knee replacement. Short-term advantages including accelerated recovery and reduction in blood loss have been demonstrated, but it remains to be investigated whether MIS is able to provide sustainable benefits and long-term outcome equivalent to conventional surgery. Successful application of MIS techniques have been confirmed in conjunction with unicompartmental knee arthroplasty (UKR) implantation, while its use with total knee arthroplasty remains experimental. Critics have expressed concern that reduced visibility may compromise implant positioning and leg alignment which could have a negative effect on prosthetic long-term survival. MIS clearly represents a unique and more technically demanding procedure, but the learning curve may perhaps overshadow the benefits. Computer navigation may help to avoid such problems but so far scientific evidence regarding definitive outcomes is lacking, and some of the MIS techniques are still in the early phases of development.

Safety and timing of resuming dabigatran after major gastrointestinal bleeding reversed by idarucizumab
Authors: Riario Sforza Gian Galeazzo , Gentile Francesco , Stock Fabio , Caggiano Francesco , Chiocca Enrica , Incorvaia Cristoforo
Published: January 2018

The recent introduction of direct oral anticoagulants, including rivaroxaban, dabigatran, apixaban, and edoxaban, for the acute treatment and secondary prevention of venous thromboembolism and in atrial fibrillation has been shown to provide greater clinical benefit than oral vitamin K antagonists. However, direct oral anticoagulants are associated with adverse events, the most common being major bleeding; such events require the reversal of the anticoagulant effects by specific agents. In this case report, we describe an 87-year-old female with atrial fibrillation treated with dabigatran who had massive rectal bleeding. Idarucizumab 5 g (2 × 2.5 g/50 mL) was successfully used to reverse dabigatran effect; subsequent to this, treatment with dabigatran was resumed, and there were no further bleeding events. This suggests that dabigatran can be safely restarted after major bleeding, but this outcome needs to be confirmed in studies involving larger groups of patients.
Self-regulation resources and physical activity participation among adults with type 2 diabetes
Authors: Castonguay Alexandre , Miquelon Paule , Boudreau François
Published: January 2018

Physical activity plays a crucial role in the prevention and treatment of type 2 diabetes. Therefore, it is important to understand why so few adults with type 2 diabetes regularly engage in physical activity. The role of self-regulation in the context of health-related behavior adherence, especially in terms of physical activity engagement and adherence, has largely been reviewed based on the strength energy model. Building on this line of research, the aim of this theoretical work was to highlight how self-regulation and ego depletion can influence the lower rate of physical activity participation among adults with type 2 diabetes, compared to adults from the general population.
Making the most of the waiting room: Electronic patient engagement, a mixed methods study
Authors: Coathup Victoria , Finlay Teresa , Teare Harriet JA , Kaye Jane , South Matthew , Watt Fiona E , Luqmani Raashid
Published: January 2018

Objective

The purpose of this study was to explore whether patients with musculoskeletal conditions would agree to use digital technologies to learn about research registries and make a decision about signing up whilst in the clinic waiting room.

Methods

Patients were recruited from four hospital clinics across Oxfordshire. We used an explanatory mixed methods design with two sequential phases comprising an exploratory, cross-sectional questionnaire ( n = 84), followed by focus group interviews ( n = 8) to provide context for the findings from the questionnaire. Multivariate ordinal logistic regression models were used to explore relationships between patient preferences and characteristics. Thematic analysis was used to understand the reasons for patient preferences regarding digital technologies and research registries.

Results

As participants' age increased, they were more likely to report a preference for face-to-face recruitment methods compared to those using digital technologies. Findings from the focus groups indicated this was primarily due to a fear of technology and physical limitations associated with a patient's condition. Patients also reported a preference for making a decision about signing up at a later date, which was attributed to patients feeling distracted whilst in the waiting room due to anxieties related to their upcoming appointment.

Conclusions

Many patients with musculoskeletal conditions in the UK may be interested in learning about opportunities to participate in research whilst using digital technologies within the waiting room. The results suggest the need for choice regarding the presentation and format of information and whether it can be accessed at a later date at home.

Nursing students need an understanding of how nurses care for people's health from a global perspective. The aim of this study was to explore how nurses can contribute to health from the perspectives of first-year nursing students in Scandinavia (Sweden, Norway) and Indonesia. Data were collected using an open-ended question about nurses’ contribution to health, and analysed using qualitative content analysis. Three common categories emerged: ‘Promoting health and preventing disease’, ‘Performing care and treatment’, ‘Establishing a relationship with patients and being compassionate’. ‘Possessing and implementing knowledge and skills’ was common to Norway and Indonesia. ‘Being a team member’ was emphasised by the Indonesian participants. The Norwegian participants focused on health promotion, whereas those from Indonesia prioritised disease prevention. The Scandinavian participants emphasised individuality, while those from Indonesia focused on the community. The findings indicate that nursing education should take account of different cultures and include student exchange programmes.

Published: January 2018

This study describes an intervention developed to implement several best transition practices with a high risk/high need population. In all, 116 students with disabilities from a charter school for dropouts participated. All students were interviewed at different points in time to track their progress as they completed the program. Records of participant’s activities and outcomes were collected. Results suggest a positive impact on students’ graduation rate (95%), enrollment in vocational rehabilitation (100%), proportion of students obtaining certificates for employment (56%), and paid internship (37%). Overall, 35% of the vocational rehabilitation cases were closed successfully with students meeting the 90-day employment requirement after graduation. Results inform future work on the implementation of interventions designed to help low-income minority youth with disabilities.
Upper Extremity Functional Status of Female Youth Softball Pitchers Using the Kerlan-Jobe Orthopaedic Clinic Questionnaire
Authors: Holtz Kaila A. , O’Connor Russell J.
Published: January 2018

Background:

Softball is a popular sport with a high incidence of upper extremity injuries. The Kerlan-Jobe Orthopaedic Clinic (KJOC) questionnaire is a validated performance and functional assessment tool used in overhead athletes. Upper extremity pain patterns and baseline KJOC scores have not been reported for active female youth softball pitchers.

Purpose/Hypothesis:

The purpose of this study was to establish the prevalence of upper extremity pain and its effect in female youth softball pitchers over a competitive season. We hypothesized that participants who missed time due to injury in the past year would have lower KJOC scores.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

Fifty-three female softball pitchers aged 12 to 18 years were recruited from softball clinics in Vancouver, British Columbia, Canada. All participants self-identified as a pitcher on a competitive travel team. Participants were administered the KJOC questionnaire before and during the playing season. Missed time due to injury in the past year, current pain patterns, and KJOC scores were primary outcomes.

Results:

The mean (±SD) preseason KJOC score was 87.2 ± 10.6. In the preseason, 22.6% of pitchers reported playing with arm trouble, and 32.1% missed time due to injury in the past year. The mean KJOC score for pitchers reporting a previous injury (n = 17) was significantly lower compared with those without an injury (n = 36) (79.5 ± 13.8 vs 90.9 ± 6.2, respectively; P = .02). The posterior shoulder was the most commonly reported pain location. For the cohort completing the questionnaire both before and during the playing season (n = 35), mean KJOC scores did not change significantly over the playing season ( P = .64). Lower preseason KJOC scores were significantly related to the in-season injury risk ( P = .016). Pitchers with a preseason score of less than 90 had a 3.5 (95% CI, 1.1-11.2) times greater risk of reporting an in-season injury.

Conclusion:

Female youth softball pitchers have a high baseline functional status. However, 1 in 3 pitchers reported missed time due to injury in the previous year, and shoulder pain was more prevalent than elbow pain. The KJOC questionnaire can be used by coaches, researchers, and clinicians to identify youth softball pitchers at risk for injuries who may benefit from interventions.
Education Coverage in Television News: A Typology and Analysis of 35 Years of Topics
Authors: Coe Kevin , Kuttner Paul J.
Published: January 2018

News media play a significant role in the education policy arena, informing the public about pressing issues and influencing how such issues are prioritized and understood. For this reason, researchers are increasingly raising concerns about how much attention news media give to education, which topics are covered, and how topics are addressed. In this article, the authors advance this growing body of research through a quantitative content analysis of the topics in national television news coverage of pre-K–12 (early childhood through high school) education in the United States over the past 35 years. The authors present their typology of education topics, providing a foundation for future research in this area, and analyze major trends. This article also serves as an introduction to a new data set: 2,322 abstracts, representing all substantial education news coverage from the three major evening news networks, included as an online appendix.
Does stroke health promotion increase awareness of appropriate behavioural response? Impact of the face, arm, speech and time (FAST) campaign on population knowledge of stroke risk factors, warning signs and emergency response
Authors: Hickey Anne , Mellon Lisa , Williams David , Shelley Emer , Conroy Ronan M
Published: January 2018

Introduction

Inability to identify stroke warning signs accurately is an important cause of delay in seeking medical attention, leading to potential ineligibility for acute intervention. We report on post-campaign findings (wave 2) of national surveys to estimate changes in population knowledge following a media-based Face, Arm, Speech, Time stroke awareness campaign, comparing findings to those of a pre-campaign population survey (wave 1). Participants and methods: One thousand and ten randomly selected adults (18+) completed the Stroke Awareness Questionnaire on knowledge of warning signs, risk factors and response to stroke at wave 2 and findings were compared to wave 1 survey results. Logistic regression was used to examine the association between demographic characteristics and self-reported risk factors with knowledge of stroke and emergency response.

Results

No significant differences existed in the ability of respondents to define stroke or to identify two or more stroke risk factors between waves 1 and 2 surveys (71% and 70%, respectively). Respondents to the wave 2 survey were five times more likely (odds ratio 4.9, p < .001) than those responding at wave 1 to know at least two warning signs of stroke (67% vs. 31%, respectively), specifically those targeted by the Face, Arm, Speech, Time campaign. While significant improvement in intention to call an ambulance was noted (odds ratio 1.5, p < .001, 57% at wave 2 compared to 47% at wave 1), for almost half of respondents (43%) this would not have been their first response to stroke. Less than 5% of respondents to both surveys identified thrombolysis as an emergency treatment for stroke (3.9% at wave 2 compared to 1.8% at wave 1).

Discussion

Although significant improvements were made in several areas of stroke knowledge and intended response, awareness of acute stroke interventions was poor and intended behavioural response was suboptimal.

Conclusion

Findings from this study indicate need for targeted campaigns to improve population understanding of the reasons underlying the importance of rapid emergency response to stroke.
Toponymic assemblages, resistance, and the politics of planning in Vancouver, Canada
Authors: Wideman Trevor J , Masuda Jeffrey R
Published: January 2018

The marginalized and impoverished Downtown Eastside neighbourhood of Vancouver, Canada has long been subjected to planning programs that have aimed to solve area problems through strategic government intervention. The 2011–2014 Local Area Planning Process, led by the City of Vancouver in consultation with local actors, represents the most recent of such programs. Despite the Local Area Planning Process’s stated goal of inclusive participation, the resultant Downtown Eastside plan transformed the political landscape of the neighbourhood and met with derision from stakeholders for its potential to generate dramatic capital-led transformations. In this paper, we critique participatory planning through a case study of the Local Area Planning Process. We utilize a lens of critical toponymy (the investigation of the historical and political implications of place naming) as a methodological tool to examine planning technologies of power and their mobilization through governmental processes. We deploy a novel approach to toponymy, drawing on assemblage theory, that presents toponymy as a radically open and dynamic process mobilized relationally through a multiplicity of discourses and materialities. Our case study demonstrates that processes of toponymic assemblage within the Downtown Eastside Local Area Planning Process worked to (1) generate new territorial conflicts, (2) depoliticize community activism, and (3) co-opt racialized and class-based histories of displacement and dispossession to stimulate “revitalization” (“Japantown”). On the other hand, we found that in unanticipated ways, these processes worked to stimulate anti-gentrification activism, alliances, and resistance. Our analysis of planning highlights how toponymic agency can service oppressive and marginalizing place-framings, but it can also have liberating effects – by inspiring unlikely alliances and counter-framings.
A spatio-temporal analysis of the relationship between housing renovation, socioeconomic status, and urban forest ecosystems
Authors: Steenberg James WN , Robinson Pamela J , Duinker Peter N
Published: January 2018

Urban forest ecosystems are increasingly recognized as necessary components of a city's overall sustainability. The number of municipal governments planning and implementing urban forest management programs is rising, as the benefits of urban forest ecosystems are becoming common knowledge. However, the urban forest is an exceedingly complex and vulnerable social–ecological system that presents a wide array of management challenges. One area of concern that is understudied and worthy of investigation is the effects of housing renovation activities and neighborhood revitalization on the urban forest. The purpose of this study is to investigate the possibility of renovation activity as a significant source of disturbance in urban forest ecosystems. We conducted ordinary least squares regression and geographically weighted regression analyses using canopy cover, building permit data, and socioeconomic variables in Toronto, Canada. We then conducted a parcel-level assessment of tree mortality using ortho-imagery from 2003 and 2014 and government open data describing 16 years of renovation activity. Findings suggest that renovation activity, as indicated by building permit abundance, is a possible cause of tree mortality and subsequently a source of urban forest disturbance. Our findings also suggest that the relationship between renovation activity and canopy cover is highly complex, and is likely influenced by residential tree planting rates, land use mix, and different trajectories of urban change.
Cost-effectiveness of Open Reduction and Internal Fixation Compared With Hemiarthroplasty in the Management of Complex Proximal Humerus Fractures
Authors: Thorsness Robert J , Iannuzzi James C , Shields Edward J , Noyes Katia , Voloshin Ilya
Published: January 2018

Objectives

To determine if open reduction and internal fixation (ORIF) is more cost-effective than hemiarthroplasty (HA) in the management of proximal humerus fracture.

Design

Retrospective cohort study with cost-effectiveness analysis.

Setting

Tertiary referral center in Rochester, NY.

Patients/participants

The records of 459 consecutive patients in whom a proximal humerus fracture was treated surgically at our institution between the years 2002 and 2012 were studied retrospectively. We identified 30 consecutive patients with a mean follow-up of 60.3 months (13.6–134.5 months) of which 15 patients underwent primary ORIF and another 15 underwent primary HA for the management of head-splitting fracture or fracture-dislocation of the proximal humerus.

Intervention

HA or ORIF for the management of proximal humerus fracture.

Main outcome measurements

SF-36 scores were converted to utility weights, and a cost-effectiveness model was designed to evaluated ORIF and HA.

Results

Given the baseline assumptions, ORIF was slightly more costly but also more effective (0.75 quality-adjusted life years [QALY] vs 0.67 QALY) than HA. The incremental cost-effectiveness ratio (ICER) was $5319/QALY for ORIF compared to HA, which is less than the cost-effectiveness standard utilized based on a willingness to pay of $50,000/QALY.

Conclusions

Compared to HA, ORIF is the more cost-effective approach for the surgical management of complex proximal humerus fractures. These data are limited by patient selection which would impact the relative utility scores. These results suggest that ORIF should be considered the preferable surgical approach given payer and patient perspectives. Level of Evidence: This is a Level III retrospective, cohort therapeutic study.
Open Sharing of Data on Close Relationships and Other Sensitive Social Psychological Topics: Challenges, Tools, and Future Directions
Authors: Joel Samantha , Eastwick Paul W. , Finkel Eli J.
Published: January 2018

This article reports on an adversarial (but friendly) collaboration examining the issues that lie at the intersection of confidentiality and open-data practices. We describe the process we followed to share our data for a speed-dating article we recently published in Psychological Science (Joel, Eastwick, & Finkel, 2017) and provide a summary of the issues we considered and addressed along the way. As we drafted the present article, the third author became unsure, in retrospect, about some of the procedures we had followed, especially if our approach were to be perceived as a model for open-data decisions in other, more typical cases involving nonindependent data. This article addresses these concerns, but also identifies areas of consensus. All three authors agree that there remains an unmet need for guidelines and other resources to help researchers address the challenges of sharing data that cover sensitive topics, particularly nonindependent data collected from pairs and groups (e.g., romantic couples, work teams, therapy groups). We conclude with a discussion of new tools that could be developed to help scholars who have collected such data to increase the transparency of their research while simultaneously protecting the confidentiality of the participants.
Practical Solutions for Sharing Data and Materials From Psychological Research
Authors: Gilmore Rick O. , Kennedy Joy Lorenzo , Adolph Karen E.
Published: January 2018

Widespread sharing of data and materials (including displays and text- and video-based descriptions of experimental procedures) will improve the reproducibility of psychological science and accelerate the pace of discovery. In this article, we discuss some of the challenges to open sharing and offer practical solutions for researchers who wish to share more of the products—and process—of their research. Many of these solutions were devised by the Databrary.org data library for storing and sharing video, audio, and other forms of sensitive or personally identifiable data. We also discuss ways in which researchers can make shared data and materials easier for others to find and reuse. Widely adopted, these solutions and practices will increase transparency and speed progress in psychological science.

Published: January 2018

The COPD Patient Management European Trial (COMET) investigated the efficacy and safety of a home-based COPD disease management intervention for severe COPD patients.

The study was an international open-design clinical trial in COPD patients (forced expiratory volume in 1 s <50% of predicted value) randomised 1:1 to the disease management intervention or to the usual management practices at the study centre. The disease management intervention included a self-management programme, home telemonitoring, care coordination and medical management. The primary end-point was the number of unplanned all-cause hospitalisation days in the intention-to-treat (ITT) population. Secondary end-points included acute care hospitalisation days, BODE (body mass index, airflow obstruction, dyspnoea and exercise) index and exacerbations. Safety end-points included adverse events and deaths.

For the 157 (disease management) and 162 (usual management) patients eligible for ITT analyses, all-cause hospitalisation days per year (mean±sd) were 17.4±35.4 and 22.6±41.8, respectively (mean difference −5.3, 95% CI −13.7 to −3.1; p=0.16). The disease management group had fewer per-protocol acute care hospitalisation days per year (p=0.047), a lower BODE index (p=0.01) and a lower mortality rate (1.9%versus14.2%; p<0.001), with no difference in exacerbation frequency. Patient profiles and hospitalisation practices varied substantially across countries.

The COMET disease management intervention did not significantly reduce unplanned all-cause hospitalisation days, but reduced acute care hospitalisation days and mortality in severe COPD patients.
Mental capacity: Different models and their controversies
Authors: Murray Brian Joseph
Published: January 2018

Modern legislation in the UK addressing the issue of decision-making ability uses tests of mental capacity based on the individual's ability to understand relevant information given to them. Alternative models of mental capacity do exist, but are largely considered defunct. This article reviews these alternative models and considers their importance. Far from being irrelevant to modern views on mental capacity, these models have already been incorporated into legislation such as the Mental Capacity Act 2005. A better understanding of these models can improve clinicians’ understanding of mental capacity in general. Modern controversies such as the impact of the United Nations Convention on the Rights of Persons with Disabilities (CRPD) are discussed and ways in which our understanding of mental capacity may have to change in the future are addressed.

LEARNING OBJECTIVES

•

Appreciate the different ways of considering an individual's mental capacity

•

Understand the primacy and limitations of the functional test of mental capacity

•

Use this understanding to manage potential conflicts or disagreements when considering an individual's mental capacity
How evolutionary thinking can help us to understand ADHD
Authors: Swanepoel Annie , Music Graham , Launer John , Reiss Michael J.
Published: January 2018

We argue that current debates about attention-deficit hyperactivity disorder (ADHD) can be considered afresh using an evolutionary lens. We show how the symptoms of ADHD can often be considered adaptive to their specific environment. We suggest that, from an evolutionary point of view, ADHD symptoms might be understood to result from an ‘evolutionary mismatch’, in which current environmental demands do not fit with what evolution has prepared us to cope with. For example, in our ancestral environment of evolutionary adaptedness (EEA), children were not expected to sit still and concentrate on academic tasks for many hours a day. Understanding ADHD in terms of such a ‘mismatch’ raises significant issues regarding the management of childhood ADHD, including ethical ones. An approach based on the concept of mismatch could provide an alternative to current debates on whether ADHD results from nature or nurture and whether it is under- or over-diagnosed. It would allow clinicians and policy makers to take both the child and the environment into account and consider what might be desirable and feasible, both in society and for specific children, to lessen the mismatch.

LEARNING OBJECTIVES

•

Grasp the concept of ADHD as an ‘evolutionary mismatch’

•

Understand the issues raised by this perspective, including ethical ones

•

Appreciate how a transparent discussion of these issues might inform decisions about management, medication and schooling
The mini-PAT as a multi-source feedback tool for trainees in child and adolescent psychiatry: Assessing whether it is fit for purpose
Authors: Salmon Gill , Pugsley Lesley
Published: January 2018

This paper discusses the research supporting the use of multi-source feedback (MSF) for doctors and describes the mini-Peer Assessment Tool (mini-PAT), the MSF instrument currently used to assess trainees in child and adolescent psychiatry. The relevance of issues raised in the literature about MSF tools in general is examined in relation to trainees in child and adolescent psychiatry as well as the appropriateness of the mini-PAT for this group. Suggestions for change including modifications to existing MSF tools or the development of a specialty-specific MSF instrument are offered.

Published: January 2018

The middle ear epithelium is derived from neural crest and endoderm, which line distinct regions of the middle ear cavity. Here, we investigate the distribution of putative stem cell markers in the middle ear, combined with an analysis of the location of label-retaining cells (LRCs) to create a map of the middle ear mucosa. We show that proliferating cells and LRCs were associated with specific regions of the ear epithelium, concentrated in the hypotympanum at the base of the auditory bulla and around the ear drum. Sox2 was widely expressed in the endodermally derived ciliated pseudostratified epithelium of the hypotympanum. This part of the middle ear showed high levels of Wnt activity, as indicated by the expression of Axin2, a readout of Wnt signalling. Keratin 5 showed a more restricted expression within the basal cells of this region, with very little overlap between the Sox2- and keratin 5-positive epithelium, indicating that these genes mark distinct populations. Little expression of Sox2 or keratin 5 was observed in the neural crest-derived middle ear epithelium that lined the promontory, except in cases of otitis media when this epithelium underwent hyperplasia. This study lays the foundation for furthering our understanding of homeostasis and repair in the middle ear.
Behavioural responses to infrasonic particle acceleration in cuttlefish
Authors: Wilson Maria , Haga Jens Ådne Rekkedal , Karlsen Hans Erik
Published: January 2018

Attacks by aquatic predators generate frontal water disturbances characterised by low-frequency gradients in pressure and particle motion. Low-frequency hearing is highly developed in cephalopods. Thus, we examined behavioural responses in juvenile cuttlefish to infrasonic accelerations mimicking main aspects of the hydrodynamic signals created by predators. In the experimental set-up, animals and their surrounding water moved as a unit to minimise lateral line activation and to allow examination of the contribution by the inner ear. Behavioural responses were tested in light versus darkness and after food deprivation following a ‘simulated’ hunting opportunity. At low acceleration levels, colour change threshold at 3, 5 and 9 Hz was 0.028, 0.038 and 0.035 m s−2, respectively. At higher stimulus levels, jet-propulsed escape responses thresholds in daylight were 0.043, 0.065 and 0.069 m s−2 at 3, 5 and 9 Hz, respectively, and not significantly different from the corresponding darkness thresholds of 0.043, 0.071 and 0.064 m s−2. In a simulated hunting mode, escape thresholds were significantly higher at 3 Hz (0.118 m s−2) but not at 9 Hz (0.134 m s−2). Escape responses were directional, and overall followed the direction of the initial particle acceleration, with mean escape angles from 313 to 33 deg for all three experiments. Thus, in the wild, particle acceleration might cause escape responses directed away from striking predators but towards suction-feeding predators. We suggest that cuttlefish jet-propulsed escape behaviour has evolved to be elicited by the early hydrodynamic disturbances generated during predator encounters, and that the inner ear plays an essential role in the acoustic escape responses.
Reproductive biology of blue swimming crab, Portunus segnis (Forskal, 1775) in Yumurtalık Cove, Northeastern Mediterranean, Turkey
Authors: TURELI CANAN , YESILYURT IREM NUR
Published: January 2018

Blue swimming crab, Portunus segnis is a Lessepsian migrant into the Mediterranean and little is known about the biology of it in Iskenderun Bay, Northeastern Mediterranean, Turkey. In the present study the sex ratio, gonadal development stages, gonadosomatic index, size at first sexual maturity, and the fecundity of P. segnis were examined. The specimens of P. segnis were collected monthly from July 2014 to June 2015 (except February) with trawl net from the Yumurtalık Cove. The crabs were found throughout the year and were abundant between July to October (74%). Carapace width range of all samples was between 38.1-163.17 mm, and body weight ranged from 3.46-324.36 g. The population sex ratio was obtained Male:Female=0.7:1 which showed more abundant female population. Fifty percent of the female crabs attained sexual maturity when they reached the sized of 115-119.99 mm CW. The ovigerous female crabs ranging between 101.39- 154.03 mm CW can produced 139379 to 2745236 eggs. The mean fecundity of P. segnis was 1070425±580978 eggs with a mean carapace width of 130.04±12.77 mm. In Yumurtalık Cove, breeding season of P. segnis were observed throughout the year, except winter. Further studies are needed for assessing the reproductive biology of blue crabs in other locations of Turkey.
Introduction of a new Indo-Pacific marine cladoceran to the Mediterranean Sea
Authors: TERBIYIK KURT TUBA , POLAT SEVIM
Published: January 2018

Pleopis schmackeri, a podonid cladoceran not previously recorded in the Mediterranean Sea, was found in the İskenderun Bay for the first time. The samples were collected seasonally during 2012–2015 in the coastal area of İskenderun Bay using a WP-2 zooplankton net (200 µm). Six cladoceran species were found in total, and Penilia avirostris, Pseudevadne tergestina and Evadne spinifera constituted the bulk of the population, while the contribution of P. schmackeri was very low. Although only a single individual was observed in July 2012, the abundance and frequency of P. schmackeri increased in the following years, attaining the abundance of 25.10 ind.m-3 in 2015. Thus, P. schmackeri could be considered as established in İskenderun Bay; however, it seems that it did not affect the distribution of other cladoceran species in the area up to now. P. schmackeri could have entered in İskenderun Bay either as Lessepsian migrant or by ballast waters of commercial ships.
The arrival of a second ‘Lessepsian sprinter’? A first record of the red cornetfish Fistularia petimba in the Eastern Mediterranean
Authors: STERN NIR , PAZ GUY , YUDKOVSKY YANA , LUBINEVSKY HADAS , RINKEVICH BARUCH
Published: January 2018

Here we document the first occurrence of the red cornetfish Fistularia petimba in the Levantine Basin. This species identity has been confirmed using morphological and molecular tools, and is presented here with simplified illustrations for accurate future identification. This report voices a concern regarding another blitz invasion of a cornetfish into the Mediterranean, following its Lessepsian sprinter congeneric, F. commersonii, one of the most efficacious invaders of the Mediterranean Sea. The wide intra-specific genetic distances found between sympatric F. petimba specimens in the available literature resources may also demonstrate the presence of cryptic diversity within this taxon.
