Surgical Safety Checklists Briefings: Perceived Efficacy and Team Member Involvement

Researchers have shown inconsistencies in compliance, outcomes and attitudes of surgical team members related to surgical safety checklist briefings. The purpose of this study was to examine surgical circulator and scrub practitioners’ perceptions of safety checklist briefings and team member involvement, and to identify potential improvements in the process based on those perceptions. An anonymous survey was conducted with members of the Association of periOperative Registered Nurses (AORN) and the Association of Surgical Technologists (AST). Questions focused on perceptions of checklist briefing efficacy and team member involvement in safety practices. From the 346 usable responses, a third respondent group of self-identified perioperative leaders emerged. Significant results were obtained related to leaders’ perceptions, post-procedure briefings and various perceptions of team member involvement. Study results indicate that variances in safety practices continue as perceived by surgical team members thus presenting opportunities for further examination and improvement of processes in reducing surgical errors.
Perioperative Nurses' Perceptions and Experiences of Continuing Professional Education

This article presents an overview of perioperative nurses' perceptions and experiences of continuing professional education (CPE). Four themes emerged from 23 interviews: attitudes and culture (background); deciding to study (going in); student experience (process); and outcomes (going out). My findings indicate transferability of other studies to perioperative nursing, and suggest that CPE is associated with increased social status and doctor-nurse collaboration. My work also illuminates the concept of ‘secret study’.
The role of the miR‐200 family in epithelial–mesenchymal transition in colorectal cancer: a systematic review

Colorectal cancer (CRC) is associated with significant morbidity and mortality as many patients are diagnosed with advanced stage disease. MicroRNAs are small, noncoding RNA molecules that have a major role in gene expression regulation and are dysregulated in CRC. The miR‐200 family is involved in epithelial–mesenchymal transition (EMT). This systematic review describes the roles of the miR‐200 family in EMT in CRC. A search of electronic databases (PubMed and Embase) was conducted between January 2000 and July 2017. Both in vitro and human studies reporting on the miR‐200 family and CRC were included. Studies describing molecular pathways and the role of the miR‐200 family in the diagnostic and therapeutic management of CRC were analyzed. Thirty‐four studies (22 in vitro and 18 human studies) were included. miR‐200 family expression is regulated epigenetically and via transcriptional factor regulation. In vitro studies show that transfection of miR‐200 family members into chemo‐resistant colon cancer cell lines results in improved chemo‐sensitivity and epithelial phenotype restoration. There is intra‐tumoral variability in the tissue expression of miR‐200 family members with decreased expression at the invasive front. Clinical studies in CRC patients have shown decreased primary tumor tissue expression of miR‐429, miR‐200a and miR‐200c may be associated with worse survival. Conversely, increased blood levels of miR‐141, miR‐200a and miR‐200c may be associated with worse outcomes. The miR‐200 family has a central role in EMT. The miR200 family has potential for both prognostic and therapeutic management of CRC.
A Dichotomy Theorem for Nonuniform CSPs

In a non-uniform Constraint Satisfaction problem CSP(&#x0393;), where G is a set of relations on a finite set A, the goal is to find an assignment of values to variables subject to constraints imposed on specified sets of variables using the relations from &#x0393;. The Dichotomy Conjecture for the non-uniform CSP states that for every constraint language \Gm the problem CSP(&#x0393;) is either solvable in polynomial time or is NP-complete. It was proposed by Feder and Vardi in their seminal 1993 paper. In this paper we confirm the Dichotomy Conjecture.
Post-Silicon Test Flow for Aging Prediction

Aging as a reliability parameter is often tested with elevated temperature or supply voltage (burn-in) environment, which is expensive and may damage product in the process. It has been found that circuit aging is primary due to signal stress conditions. And the aging effects will manifest on long critical paths for induced extra delays. In this paper, we proposed a test flow to predict timing-failure age caused by Negative-Bias Temperature Instability (NBTI). First, the flow measures critical path delays (which may variate due to process variation). Given the tested path delays, we sample a batch of delay profiles of cells on tested paths. Next, we simulate above delay profiles with known signal stress conditions (from functional simulation) to predict the failure age. In experimental results, comparing with reference golden sample (with known ages), we can obtain a very close prediction of failure ages (
A MapReduce-Based Ensemble Learning Method with Multiple Classifier Types and Diversity for Condition-Based Maintenance with Concept Drifts

Condition-based maintenance in Industry 4.0 collects a huge amount of production datastreams continuously from the Internet of Things attached to machines to forecast the time when to maintain machines or replace components. However, as conditions of machines change dynamically with time owing to machine aging, malfunction, or replacement, the concept of capturing the forecasting pattern from the datastream could drift unpredictably, so it is hard to find a robust forecasting method with high precision. Therefore, this work proposes an ensemble learning method with multiple classifier types and diversity for condition-based maintenance in manufacturing industries, to address the bias problem when using only one base classifier type. Aside from manipulating data diversity, this method includes multiple classifier types, dynamic weight adjusting, and databased adaption to concept drifts for offline learning models, to promote precision of the forecasting model and precisely detect and adapt to concept drifts. With these features, the proposed method requires powerful computing resources to efficiently respond to practical condition-based maintenance applications. Therefore, the implementation of this method based on the MapReduce framework is proposed to increase computational efficiency. Simulation results show that this method can detect and adapt to all concept drifts with a high precision rate.
Effectiveness of aquatic exercises compared to patient-education on health status in individuals with knee osteoarthritis: a randomized controlled trial

Objective: To compare the effectiveness of aquatic exercises with patient-education in individuals with knee osteoarthritis. Design: Randomized controlled trial with blinded assessor and intention-to-treat analysis. Setting: Aquatic Physiotherapy Centre and Primary Health Care Unit. Subjects: A total of 60 patients, aged 68.3 (SD = 4.8) with clinical symptoms and radiographic grading (Kellgren–Lawrence 1–4) of knee osteoarthritis were included. Interventions: An eight-week treatment protocol of aquatic exercise (n = 31) (16 individual sessions, twice a week) and an educational program (group sessions, once a week) (n = 29). Main measures: Before, after eight-week intervention, and a three-month follow-up with results for the following outcome measures: pain, function, quality of life, functional mobility, and depression. Results: At the end of treatment, the WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) functional capacity values reduced in favour of the aquatic exercise group for both the total score MD (mean difference) = –14.2; 95% CI (confidence interval) (−18; −10.5), P = 0.04 and the pain domain MD = −3.8 points; 95% CI (−8.71; −1), P = 0.021. The total score also reduced in the follow-up: MD = −12.3 points; 95% CI (−24.7; −6.1), P = 0.017. No differences were found for the outcomes functional mobility or depression. Conclusion: Aquatic exercise improved pain and function after eight weeks, and function at the three-month follow-up compared to the patient-education program.
The type IV secretion system core component VirB8 interacts via the β1‐strand with VirB10

In this work, we provide evidence for the interactions between VirB8 and VirB10, two core components of the type IV secretion system (T4SS). Using nuclear magnetic resonance experiments, we identified residues on the β1‐strand of Brucella VirB8 that undergo chemical shift changes in the presence of VirB10. Bacterial two‐hybrid experiments confirm the importance of the β1‐strand, whereas phage display experiments suggest that the α2‐helix of VirB8 may also contribute to the interaction with VirB10. Conjugation assays using the VirB8 homolog TraE as a model show that several residues on the β1‐strand of TraE are important for T4SS function. Together, our results suggest that the β1‐strand of VirB8‐like proteins is essential for their interaction with VirB10 in the T4SS complex.
Critical design and realization aspects of glyph-based 3D data visualization

Glyphs are useful for the effective visualization of multi-variate data. They allow for easily relating multiple data attributes to each other in a coherent visualization approach. While the basic principle of glyph-based visualization has been known for a long time, scientific interest has recently increased focus on the question of how to achieve a clever and successful glyph design. Along this newer trend, we present a structured discussion of several critical design aspects of glyph-based visualization with a special focus on 3D data. For three consecutive steps of data mapping, glyph instantiation, and rendering, we identify a number of design considerations. We illustrate our discussion with a new glyph-based visualization of time-dependent 3D simulation data and demonstrate how effective results are achieved.
Simulation of three-phase motor drive system with bearing discharge process

Due to high-frequency common-mode (CM) voltage and induced CM current, bearings of inverter-driven induction machines suffer from electrical discharge machining(EDM) which may cause premature bearing failures such as damage of the bearing surfaces and degradation of lubrication grease. Meanwhile, the bearing EDM process is always accompanied by conducted and radiated electromagnetic interference (EMI) emissions. In this paper, simulation of a 5.5 kW induction machine driven by a PWM-controlled voltage source inverter (VSI) is introduced and an improved discharge circuit across the motor bearing is designed to simulate the EDM process. High frequency modelling of the cable and induction machine matches well with measurement results. EDM process happens when a controlled switch across the machine bearing closes, which means a sudden drop of bearing voltage. During the discharge instant, a harmful EDM current flows through the compromised bearing and reduces bearing life.
Appearance similarity evaluation for Android applications

Android, one of the most popular mobile operating system in recent year, attracts device users by its numerous applications. Google built Google Play Store as its official Android market for Android users to search and install apps. However, with the increasingly growth of the number of apps in Android marketplaces, some undesirable apps began to turn up. Plagiarisms and malware are two main kinds of those undesirable applications. For plagiarisms, they pirate other developers' work. As for malware, one of the most common way of spread is inducing users to install by their graphical user interface (GUI) similarity. Therefore, in this paper, we put forward a method to detect plagiarisms or malware which conceal themselves as a legitimate pre-existed app in Android marketplaces by their appearance. The main method we design is to compare the GUI similarity among Android apps and pick up some apps with high similarity on their appearance. In detail, we extract some features of apps and compute their similarity by their feature vectors. At last, we evaluate our design with 2,000 apps in both official and alternative Android marketplaces to find out such appearance similar apps in our dataset.
Communication and support from health-care professionals to families, with dependent children, following the diagnosis of parental life-limiting illness: A systematic review

Background: Communication between parents and their children about parental life-limiting illness is stressful. Parents want support from health-care professionals; however, the extent of this support is not known. Awareness of family’s needs would help ensure appropriate support. Aim: To find the current literature exploring (1) how parents with a life-limiting illness, who have dependent children, perceive health-care professionals’ communication with them about the illness, diagnosis and treatments, including how social, practical and emotional support is offered to them and (2) how this contributes to the parents’ feelings of supporting their children. Design: A systematic literature review and narrative synthesis. Data sources: Embase, MEDLINE, PsycINFO, CINAHL and ASSIA ProQuest were searched in November 2015 for studies assessing communication between health-care professionals and parents about how to talk with their children about the parent’s illness. Results: There were 1342 records identified, five qualitative studies met the inclusion criteria (55 ill parents, 11 spouses/carers, 26 children and 16 health-care professionals). Parents wanted information from health-care professionals about how to talk to their children about the illness; this was not routinely offered. Children also want to talk with a health-care professional about their parents’ illness. Health-care professionals are concerned that conversations with parents and their children will be too difficult and time-consuming. Conclusion: Parents with a life-limiting illness want support from their health-care professionals about how to communicate with their children about the illness. Their children look to health-care professionals for information about their parent’s illness. Health-care professionals, have an important role but appear reluctant to address these concerns because of fears of insufficient time and expertise.
Patient Assessment in Recovery

Recovery rooms hold an undeniably important place in the perioperative journey for the patient. It is here that possible complications following anaesthesia or surgery can be detected and rectified and patients can be made comfortable before returning to the ward. This article explores the vital aspects of patient assessment which are important for any recovery practitioner to consider.
The Splicing Factor hnRNPA1 Regulates Alternate Splicing of the MYLK Gene

&NA; Profound lung vascular permeability is a cardinal feature of acute respiratory distress syndrome (ARDS) and ventilator‐induced lung injury (VILI), two syndromes known to centrally involve the nonmuscle isoform of myosin light chain kinase (nmMLCK) in vascular barrier dysregulation. Two main splice variants, nmMLCK1 and nmMLCK2, are well represented in human lung endothelial cells and encoded by MYLK, and they differ only in the presence of exon 11 in nmMLCK1, which contains critical phosphorylation sites (Y464 and Y471) that influence nmMLCK enzymatic activity, cellular translocation, and localization in response to vascular agonists. We recently demonstrated the functional role of SNPs in altering MYLK splicing, and in the present study we sought to identify the role of splicing factors in the generation of nmMLCK1 and nmMLCK2 spliced variants. Using bioinformatic in silico approaches, we identified a putative binding site for heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1), a recognized splicing factor. We verified hnRNPA1 binding to MYLK by gel shift analyses and that hnRNPA1 gene and protein expression is upregulated in mouse lungs obtained from preclinical models of ARDS and VILI and in human endothelial cells exposed to 18% cyclic stretch, a model that reproduces the excessive mechanical stress observed in VILI. Using an MYLK minigene approach, we established a direct role of hnRNPA1 in MYLK splicing and in the context of 18% cyclic stretch. In summary, these data indicate an important regulatory role for hnRNPA1 in MYLK splicing, and they increase understanding of MYLK splicing in the regulation of lung vascular integrity during acute lung inflammation and excessive mechanical stress, such as that observed in ARDS and VILI.
Analytical performance evaluation of massive MIMO systems with 1-bit DACs

By employing multiple antennas at the transmitter and the receiver sides, massive multiple input, multiple output (MIMO) schemes allow significant capacity gains. However, the implementation complexity inherent to the use of several tens or even hundreds of antennas might be too high, precluding the use of transmission techniques associated to conventional MIMO systems. In this paper we consider massive MIMO schemes employing 1-bit digital-to-analog converters (DACs) at the transmitter side. We present an analytical method for obtaining the statistical characterization of the transmitted signals. This statistical characterization allows a simple and accurate performance evaluation. It is shown that, although the nonlinear distortion effects associated to the use of 1-bit DACs can be very high, their impact on the system's performance can be minimized by employing more antennas at the transmitter side than at the receiver side. Therefore, massive MIMO systems with 1-bit DACs can be an interesting option for future broadband wireless systems.
IJCNLP-2017 Task 2: Dimensional Sentiment Analysis for Chinese Phrases

This paper presents the IJCNLP 2017 shared task on Dimensional Sentiment Analysis for Chinese Phrases (DSAP) which seeks to identify a real-value sentiment score of Chinese single words and multi-word phrases in the both valence and arousal dimensions. Valence represents the degree of pleasant and unpleasant (or positive and negative) feelings, and arousal represents the degree of excitement and calm. Of the 19 teams registered for this shared task for two-dimensional sentiment analysis, 13 submitted results. We expected that this evaluation campaign could produce more advanced dimensional sentiment analysis techniques, especially for Chinese affective computing. All data sets with gold standards and scoring script are made publicly available to researchers.
A Randomized, Nonblind, Naturalistic Comparison of Efficacy and Cognitive Outcomes With Right Unilateral, Bifrontal, and Bitemporal Electroconvulsive Therapy in Schizophrenia

Background There is little literature on the relative efficacy and cognitive safety of right unilateral (RUL), bifrontal (BF), and bitemporal (BT) electroconvulsive therapy (ECT) in schizophrenia. Methods We present a randomized, nonblind, naturalist comparison of a fixed course of 8 moderately high-dose RUL (n = 24), threshold BF (n = 27), and threshold BT (n = 31) ECT in patients with schizophrenia. Assessments included the Positive and Negative Syndrome Scale (PANSS), the Wechsler Memory Scale—Revised, and an autobiographical memory interview. A completer analysis was planned and conducted to capture the cognitive outcomes. Results The sample as a whole improved significantly on all efficacy outcomes and deteriorated significantly on all cognitive outcomes. The primary efficacy outcome, improvement in PANSS total scores, did not differ significantly across groups. The PANSS positive score (but no other subscale score) improved significantly less with RUL relative to BF and BT ECT. For autobiographical memory and for almost all Wechsler Memory Scale subtests, including memory quotient (the primary adverse effect outcome), BT ECT was associated with greater impairment than RUL or BF ECT. Importantly, all statistically significant differences between treatments were clinically small in magnitude. Conclusions In patients with schizophrenia who receive a fixed course of 8 ECTs, threshold BT ECT is associated with greater cognitive impairment across a range of measures, and moderately high-dose RUL ECT is associated with poorer efficacy against positive symptoms. Threshold BF ECT exhibits the best efficacy-cum-neurocognitive safety profile. All differences between groups, however, are small and perhaps clinically insignificant.
Single sample face recognition via lower-upper decomposition

In this paper, a new single sample face recognition approach based on lower-upper (LU) decomposition is proposed. The single sample and its transpose are decomposed to two sets of basis images respectively by LU decomposition algorithm. Two approximation images are reconstructed from the two basis image sets respectively by the experimental estimation method. The fisher linear discriminant analysis (FLDA) is used to evaluate the optimal projection space using the new training set consisting of the single sample and its two approximation images for each person. We make two main contributions: one is that we propose to decompose the single sample and its transpose using the efficient LU decomposition algorithm; the other is that we present an experimental estimation method using the fixed image size to evaluate the number of basis images, which are used to reconstruct the approximation image. The experimental results on the FERET and AR face databases indicate that the proposed method is efficient and outperforms several state-of-the-art approaches which are proposed to address the single sample per person problem.
Robust rate maximization for OFDM-based cognitive radio networks

In this paper, we propose a novel robust resource allocation method for an OFDM-based cognitive radio (CR) system. Considering noise plus interference uncertainty, the proposed method aims to maximize data rate of each CR user while the interference introduced to primary user and achievable rate of CR user remain within certain probability thresholds. With the assumption of uniform distribution of error, the robust rate maximization problem is transformed to a deterministic one solved by dual decomposition theory in a distributed way. To accelerate convergence speed, an iteration update strategy with forgetting factor is introduced instead of traditional subgradient update method. Simulation results demonstrate that the proposed algorithm has good convergence and robustness performance.
Chimpanzees know what conspecifics do and do not see

We report a series of experiments on social problem solving in chimpanzees, Pan troglodytes. In each experiment a subordinate and a dominant individual were put into competition over two pieces of food. In all experiments dominants obtained virtually all of the foods to which they had good visual and physical access. However, subordinates were successful quite often in three situations in which they had better visual access to the food than the dominant, for example, when the food was positioned so that only the subordinate (and not the dominant) could see it. In some cases, the subordinate might have been monitoring the behaviour of the dominant directly and simply avoided the food that the dominant was moving towards (which just happened to be the one it could see). In other cases, however, we ruled out this possibility by giving subordinates a small headstart and forcing them to make their choice (to go to the food that both competitors could see, or the food that only they could see) before the dominant was released into the area. Together with other recent studies, the present investigation suggests that chimpanzees know what conspecifics can and cannot see, and, furthermore, that they use this knowledge to devise effective social-cognitive strategies in naturally occurring food competition situations.
