Published: October 2017

AbstractBackgroundIn the absence of horizontal gene transfer it is possible to reconstruct the history of gene families from empirically determined orthology relations, which are equivalent toevent-labeledgene trees. Knowledge of the event labels considerably simplifies the problem of reconciling a gene treeTwith a species treesS, relative to the reconciliation problem without prior knowledge of the event types. It is well-known that optimal reconciliations in the unlabeled case may violate time-consistency and thus are not biologically feasible. Here we investigate the mathematical structure of the event labeled reconciliation problem with horizontal transfer.ResultsWe investigate the issue of time-consistency for the event-labeled version of the reconciliation problem, provide a convenient axiomatic framework, and derive a complete characterization of time-consistent reconciliations. This characterization depends on certain weak conditions on the event-labeled gene trees that reflect conditions under which evolutionary events are observable at least in principle. We give an 𝒪(|V(T)|log(|V(S)|))-time algorithm to decide whether a time-consistent reconciliation map exists. It does not require the construction of explicit timing maps, but relies entirely on the comparably easy task of checking whether a small auxiliary graph is acyclic. The algorithms are implemented in C++ using the boost graph library and are freely available athttps://github.com/Nojgaard/tc-recon.SignificanceThe combinatorial characterization of time consistency and thus biologically feasible reconciliation is an important step towards the inference of gene family histories with horizontal transfer from orthology data, i.e., without presupposed gene and species trees. The fast algorithm to decide time consistency is useful in a broader context because it constitutes an attractive component for all tools that address tree reconciliation problems.
Information retrieval of a disaster event from cross-platform social media
Authors: Shen Shi , Murzintcev Nikita , Song Changqing , Cheng Changxiu 
Published: October 2017

Purpose
The purpose of this study is to propose a method to retrieve data on an event based on a preliminary collection of event-specific hashtags.

Design/methodology/approach
Extra knowledge, or a list of events with recorded features that can be used to characterize an event and separate it from other simultaneously occurring social phenomena, is employed. The first step involves the estimation and use of the impact area to retrieve messages from Twitter. This is followed by an extraction of hashtags from these messages. After that, the noisy hashtags would be filtered out by some heuristic rules. Finally, hashtags are used to collect relevant messages from not only Twitter but also other social media platforms.

Findings
The proposed method has high selectivity and is able to collect distinct sets of hashtags even for similar simultaneous events. In addition, spatial and temporal features are sufficient to improve collecting information of disaster events.

Originality/value
This work discusses a method of information retrieval of an event from cross-platform social media. The proposed method can be applied to other studies of geographically related events.
The impacts of knowledge sharing-based value co-creation on user continuance in online communities
Authors: Chen Chen , Du Rong , Li Jin , Fan Weiguo 
Published: October 2017

Purpose
Though online communities offer unprecedented opportunities to involve people in knowledge sharing, the reasons why users would like to participate in those activities in online communities have still been under-explored. In this research, the authors aim to use the value co-creation theory to build and test a continuance usage model, which focuses more on experiential values resulted from the knowledge sharing behavior.

Design/methodology/approach
An integrative research model is built to investigate how knowledge sharing behavior affects users’ co-creation value and then drives their continuance usage in online communities. Online survey data collected from 239 Sina Microblog users in China are utilized to validate the proposed model and hypotheses.

Findings
Empirical results indicate that the knowledge sharing behavior helps improve users’ co-creation value, including customer learning value, social integrative value and hedonic value. This co-creation value can subsequently affect users’ future participation intention in online communities.

Originality/value
This paper seeks to fill the research gap by examining customers’ motivations or perceptions underlying their knowledge sharing behavior at the usage-stage, instead of the pre-usage stage mainly concentrated on by previous studies. The managerial implications can be utilized for policy making to encourage customers’ participation and operate a better online community.
Assistant principals’ perceptions of meaningful mentoring and professional development opportunities
Authors: Barnett Bruce G. , Shoho Alan R. , Okilwa Nathern S.A. 
Published: October 2017

Purpose
When assistant principals experience positive mentoring and professional development, they can obtain valuable knowledge and leadership skills from these learning opportunities. To better understand the formal and informal mechanisms assistant principals use to expand their knowledge and skills, the purpose of this paper is to examine important advice mentors provided for them and the professional learning activities that prepare them for their school leadership roles.

Design/methodology/approach
Semi-structured interviews with 69 elementary, middle, and high school assistant principals were conducted. Questions focused on the advice mentors have provided and significant learning experiences that have aided in their growth as school leaders.

Findings
Results reveal that assistant principals greatly appreciate insights from mentors about how to enhance decision-making skills, improve people and communication skills, reflect on their personal qualities and capabilities, and clarify their values and beliefs. Their preferred means for professional growth is to work with former and current administrators they trust and respect.

Originality/value
This study goes beyond examining the structural and procedural aspects of mentoring by describing highly valued advice provided by mentors affecting assistant principals’ professional development and growth. For mentoring to be effective, this study suggests that mentors should provide opportunities for assistant principals to develop their decision-making, people, and communication skills as well to clarify their personal capabilities, values, and beliefs.

BackgroundPreterm birth may leave the brain vulnerable to dysfunction. Knowledge of future neurodevelopmental delay in children born with various degrees of prematurity is needed to inform practice and policy.ObjectiveTo quantify the long‐term cognitive, motor, behavioural and academic performance of children born with different degrees of prematurity compared with term‐born children.Search strategyPubMed and Embase were searched from January 1980 to December 2016 without language restrictions.Selection criteriaObservational studies that reported neurodevelopmental outcomes from 2 years of age in children born preterm compared with a term‐born cohort.Data collection and analysisWe pooled individual estimates of standardised mean differences (SMD) and odds ratios (OR) with 95% confidence intervals using a random effects model.Main resultsWe included 74 studies (64 061 children). Preterm children had lower cognitive scores for FSIQ (SMD: −0.70; 95% CI: −0.73 to −0.66), PIQ (SMD: −0.67; 95% CI: −0.73 to −0.60) and VIQ (SMD: −0.53; 95% CI: −0.60 to −0.47). Lower scores for preterm children in motor skills, behaviour, reading, mathematics and spelling were observed at primary school age, and this persisted to secondary school age, except for mathematics. Gestational age at birth accounted for 38–48% of the observed IQ variance. ADHD was diagnosed twice as often in preterm children (OR: 1.6; 95% CI: 1.3–1.8), with a differential effect observed according to the severity of prematurity (I2 = 49.4%, P = 0.03).ConclusionsPrematurity of any degree affects the cognitive performance of children born preterm. The poor neurodevelopment persists at various ages of follow up. Parents, educators, healthcare professionals and policy makers need to take into account the additional academic, emotional and behavioural needs of these children.Tweetable abstractAdverse effect of preterm birth on a child's neurodevelopment persists up to adulthood.
Review article: A systematic review of emergency department incident classification frameworks
Authors: Murray Matthew , McCarthy Sally 
Published: October 2017

AbstractAs in any part of the hospital system, safety incidents can occur in the ED. These incidents arguably have a distinct character, as the ED involves unscheduled flows of urgent patients who require disparate services. To aid understanding of safety issues and support risk management of the ED, a comparison of published ED specific incident classification frameworks was performed. A review of emergency medicine, health management and general medical publications, using Ovid SP to interrogate Medline (1976–2016) was undertaken to identify any type of taxonomy or classification‐like framework for ED related incidents. These frameworks were then analysed and compared. The review identified 17 publications containing an incident classification framework. Comparison of factors and themes making up the classification constituent elements revealed some commonality, but no overall consistency, nor evolution towards an ideal framework. Inconsistency arises from differences in the evidential basis and design methodology of classifications, with design itself being an inherently subjective process. It was not possible to identify an ‘ideal’ incident classification framework for ED risk management, and there is significant variation in the selection of categories used by frameworks. The variation in classification could risk an unbalanced emphasis in findings through application of a particular framework. Design of an ED specific, ideal incident classification framework should be informed by a much wider range of theories of how organisations and systems work, in addition to clinical and human factors.

AbstractPlant phenols may accumulate in end‐stage kidney disease. The effect of hemodialysis on their plasma concentration remains poorly determined. Contingent on concentration, health‐promoting or noxious effects occur; therefore, we assessed plasma concentration in hemodialyzed patients. In total, 21 maintenance hemodialyzed patients with diuresis < 500 mL per day (with oliguria), nine hemodialyzed patients with diuresis ≥ 500 mL per day (without oliguria) and 31 healthy volunteers were included. Nine phenolic acids were identified with high‐performance liquid chromatography and total polyphenol concentration was determined with the Folin–Ciocalteu method in pre‐ or post‐hemodialysis plasma and pre‐ or intra‐hemodialysis dialysate. The concentration of total polyphenols was 27% higher in pre‐hemodialysis plasma than in that of controls (0.95 ± 0.18 mmol/L [P < 0.0001]). The concentration of total polyphenols was higher in patients with oliguria (1.01 ± 0.17) than in those without (0.84 ± 0.13 mmol/L), despite the former having more intense hemodialysis (Kt/V 1.29 ± 0.31 and 0.77 ± 0.25, respectively). Pre‐hemodialysis phenolic acid concentration in patients undergoing dialysis exceeded reference values by 3 to 34 times (3‐hydroxyphenylacetic acid and vanillic acid, respectively), from 0.69 (dihydrocaffeic acid) to 169.3 μmol/L (hippuric acid). The concentration of six phenolic acids (3‐hydroxyhippuric, caffeic, dihydrocaffeic, hippuric, homovanillic, and vanillic acid) was 1.1 (homovanillic) to 11.3 (3‐hydroxyhippuric) times higher in patients with oliguria than in those without. 4‐hydroxyhippuric acid occurred more in the plasma of patients with oliguria than in those without oliguria. A single hemodialysis session decreased total polyphenol concentration by 16% and phenolic acids from 30% (caffeic) to 58% (vanillic and 3‐hydroxyphenylacetic acid) and these compounds appeared in the dialysate. The percentage decrease (Δ%) of creatinine concentration correlated with the Δ% of total polyphenols and five phenolic acids (3‐hydroxyphenylacetic, dihydrocaffeic, hippuric, homovanillic, and vanillic acid). Urea Δ% and Kt/V correlated only with the Δ% of homovanilic acid. The results demonstrate that phenols accumulate variably in hemodialyzed patients and are differently eliminated during hemodialysis. Residual renal function ensures a lower concentration of plasma phenols.
Keeping cool: practicing domestic refrigeration and environmental responsibility
Authors: Phillips Catherine , Waitt Gordon 
Published: October 2017

AbstractDomestic refrigerators have become symbols of climate change in energy efficiency campaigns; they are equipment that both permits and prohibits the performance of environmental citizenship. However, little is known about how subjectivities and practices interact, particularly with regard to questions about refrigeration and domestic energy. What might those of us interested in household sustainability learn from the relationships among refrigerators, energy, subjectivities, and practices, and from what these may reveal about environmental responsibility? We draw on data from mixed‐method qualitative research conducted with 28 households in Wollongong, Australia, and frame the analysis in terms of social practice theory, with additional attention to subjectivity. This framing helps us develop thinking about how refrigeration is done and consider whether and how things become waste by paying closer attention to the spatial imperatives underpinning these practices. It also assists us in considering how the ongoing relationships of social and material aspects of refrigeration co‐constitute a range of subjectivities. Further, our analysis advances discussions on how household practices and identities relate to public campaigns about environmental responsibility, particularly as the latter is constructed in terms of ‘energy efficiency’.

AbstractObjectivesFluid resuscitation is the mainstay treatment to reconstitute intravascular volume and maintain end‐organ perfusion in patients with severe burns. The use of a hyperosmotic or isoosmotic solution in fluid resuscitation to manage myocardial depression and increased capillary permeability during burn shock has been debated. We conducted a systematic review and meta‐analysis to compare the efficacies of hyperosmotic and isoosmotic solutions in restoring hemodynamic stability after burn injuries.MethodsPubMed, Embase, Cochrane Library, Scopus, and ClinicalTrials.gov registry were searched. Randomized control trials evaluating the efficacy and safety of hyperosmotic and isoosmotic fluid resuscitation in patients with burn injuries were selected. Eligible trials were abstracted and assessed for the risk of bias by two reviewers and results of hemodynamic indicators in the included trials were analyzed.ResultsTen trials including 502 participants were published between 1983 and 2013. Compared with isoosmotic group, the hyperosmotic group exhibited a significant decrease in the fluid load (vol/% total body surface area [TBSA]/weight) at 24 hours postinjury, with a mean difference of −0.54 (95% confidence interval = −0.92 to −0.17). No differences were observed in the urine output, creatinine level, and mortality at 24 hours postinjury between groups.ConclusionsHyperosmotic fluid resuscitation appears to be an attractive choice for severe burns in terms of TBSA or burn depth. Further investigation is recommended before conclusive recommendation.

Review article: the role of the microcirculation in liver cirrhosis
Authors: Davies T. , Wythe S. , O'Beirne J. , Martin D. , Gilbert‐Kawai E. 
Published: October 2017

SummaryBackgroundIntrahepatic microvascular derangements and microcirculatory dysfunction are key in the development of liver cirrhosis and its associated complications. While much has been documented relating to cirrhosis and the dysfunction of the microcirculation in the liver parenchyma, far less is known about the state of the extrahepatic microcirculation and the role this may have in the pathogenesis of multiple organ failure in end stage liver cirrhosis.AimTo provide an update on the role of the microcirculation in the pathophysiology of cirrhosis and its associated complications and briefly discuss some of the imaging techniques which may be used to directly investigate the microcirculation.MethodsA Medline literature search was conducted using the following search terms: ‘cirrhosis’, ‘microcirculation’, ‘circulation’, ‘systemic’, ‘inflammation’, ‘peripheral’, ‘hepatorenal’ and ‘hepatopulmonary’.ResultsSignificant heterogeneous microvascular alterations exist in patients with cirrhosis. Data suggest that the systemic inflammation, associated with advanced cirrhosis, induces microcirculatory dysregulation and contributes to haemodynamic derangement. The resultant vasoconstriction and hypoperfusion in the systemic extrahepatic microvasculature, is likely to be instrumental in the pathophysiology of organ failure in decompensated cirrhosis, however the mechanistic action of vasoactive agents used to correct the circulatory disturbance of advanced cirrhosis is poorly understood.ConclusionsFurther research into the role of the microcirculation in patients with liver cirrhosis, will improve physicians understanding of the pathophysiology of cirrhosis, and may provide a platform for real time evaluation of an individual's microcirculatory response to vasoactive mediators, thus guiding their therapy.

SummaryBackgroundThe outcome of cholangiopathy developing in intensive care unit (ICU) is not known in patients surviving their ICU stay.AimTo perform a survey in liver units, in order to clarify the course of cholangiopathy after surviving ICU stay.MethodsThe files of the liver units affiliated to the French network for vascular liver disease were screened for cases of ICU cholangiopathy developing in patients with normal liver function tests on ICU admission, and no prior history of liver disease.ResultsBetween 2005 and 2015, 16 cases were retrieved. Extensive burns were the cause for admission to ICU in 11 patients. Serum alkaline phosphatase levels increased from day 11 (2‐46) to a peak of 15 (4‐32) × ULN on day 81 (12‐511). Magnetic resonance cholangiography showed irregularities or frank stenosis of the intrahepatic ducts, and proximal extrahepatic ducts contrasting with a normal aspect of the distal common bile duct. Follow‐up duration was 20.6 (4.7‐71.8) months. Three patients were lost to follow‐up; 2 patients died from liver failure and no patient was transplanted. One patient had worsening strictures of the intrahepatic bile ducts with jaundice. Nine patients had persistent but minor strictures of the intrahepatic bile ducts on MR cholangiography, and persistent cholestasis without jaundice. One patient had normal liver function tests.ConclusionsIn patients surviving their ICU stay, ICU cholangiopathy is not uniformly fatal in the short term or clinically symptomatic in the medium term. Preservation of the distal common bile duct appears to be a finding differentiating ICU cholangiopathy from other diffuse cholangiopathies.
