ObjectiveThe aim of the study was to evaluate the reported measurement capabilities and predictive validity of the Functional Movement Screen (FMS) for injury.MethodsThis was a prospective observational longitudinal study of 24 male footballers from a single team in England, alongside analysis of an existing database over one season (September 2015–May 2016). A preseason FMS was carried out with scores recorded by an experienced assessor and derived, retrospectively, from the three-dimensional movement data that were simultaneously captured. The assessor scores were compared with the photogrammetric system to determine measurement validity, and predictive validity was quantified by assessing sensitivity and specificity (cut-off score of 14).ResultsThe real-time assessor score matched the photogrammetric score awarded for one of the participants, was higher than the photogrammetric system for 22 participants and was lower than the photogrammetric system in 1 participant. There was no discernible relationship between FMS scores and the competencies required to be met as per the rules articulated for the allocation of a score. A higher number of total injuries were associated with higher FMS scores, whether determined through real-time assessment or codification of kinematic variables. Additionally, neither method of score determination was able to prospectively identify players at risk of serious injury.ConclusionThe FMS does not demonstrate the properties essential to be considered as a measurement scale and has neither measurement nor predictive validity. A possible reason for these observations could be the complexity in the instructions associated with the scale. Further work on eliminating redundancies and improving the measurement properties is recommended.

Published: May 2018

BackgroundTo inform discussions on rates, burden and priority-setting in relation to police violence, we quantified the number and rate of years of life lost (YLLs) due to police violence by race/ethnicity and age in the USA, 2015–2016.MethodsWe used data on the number of deaths due to police violence from ‘The Counted’, a media-based source compiled byThe Guardian. YLLs are the difference between an individual’s age at death and their corresponding standard life expectancy at age of death.ResultsThere were 57 375 and 54 754 YLLs due to police violence in 2015 and 2016, respectively. People of colour comprised 38.5% of the population, but 51.5% of YLLs. YLLs were greatest among those aged 25–34 years, and the number of YLLs at younger ages was greater among people of colour than whites.ConclusionsThe number of YLLs due to police violence is substantial. YLLs highlight that police violence disproportionately impacts young people, and the young people affected are disproportionately people of colour. Framing police violence as an important cause of deaths among young adults provides another valuable lens to motivate prevention efforts.

Published: May 2018

ObjectivesThe fit note, introduced in England, Wales and Scotland in 2010, was designed to change radically the sickness certification process from advising individuals on their inability to work to advising them on what they could do if work could be adapted. Our review aimed to evaluate the following: (1) Is the ‘maybe fit’ for work option being selected for patients? (2) Are work solutions being recommended? (3) Has the fit note increased return to work? (4) Has the fit note reduced the length of sickness absence? We considered the way in which outcomes vary according to patient demographics including type of health problem.MethodsStudies were identified by a systematic search. We included all studies of any design conducted in the UK with working age adults, aged 16 or over, from 1 April 2010 to 1 Nov 2017. Risk of bias was assessed using a modified Newcastle-Ottawa Scale.ResultsThirteen papers representing seven studies met inclusion criteria. In the largest study, ‘maybe fit’ for work was recommended in 6.5% of fit notes delivered by general practitioners (GP; n=361 801) between April 2016 and March 2017. ‘Maybe fit’ recommendations were made in 8.5%–10% of fit notes received by primary care patients in employment, and in 10%–32% of patients seen by GPs trained in the Diploma in Occupational Medicine. ‘Maybe fit’ was recommended more for women, those with higher socioeconomic status, and for physical, as opposed to psychiatric disorders. The majority of fit notes with the ‘maybe fit’ option selected included work solutions. There was inconclusive evidence to suggest that the introduction of the fit note has reduced sickness absence among patients in employment.ConclusionsFit notes represent a major shift in public policy. Our review suggests that they have been incompletely researched and not implemented as intended.
E11, brane dynamics and duality symmetries
Authors: West Peter 
Published: May 2018

Following arXiv:hep-th/0412336 we use the nonlinear realisation of the semi-direct product of [Formula: see text] and its vector representation to construct brane dynamics. The brane moves through a space-time which arises in the nonlinear realisation from the vector representation and it contains the usual embedding coordinates as well as the worldvolume fields. The resulting equations of motion are first order in derivatives and can be thought of as duality relations. Each brane carries the full [Formula: see text] symmetry and so the Cremmer–Julia duality symmetries. We apply this theory to find the dynamics of the IIA and IIB strings, the M2 and M5 branes, the IIB D3 brane as well as the one and two branes in seven dimensions.
Accurate prediction of human miRNA targets via graph modeling of the miRNA-target duplex

Published: May 2018

miRNAs are involved in many critical cellular activities through binding to their mRNA targets, e.g. in cell proliferation, differentiation, death, growth control, and developmental timing. Accurate prediction of miRNA targets can assist efficient experimental investigations on the functional roles of miRNAs. Their prediction, however, remains a challengeable task due to the lack of experimental data about the tertiary structure of miRNA-target binding duplexes. In particular, correlations of nucleotides in the binding duplexes may not be limited to the canonical Watson Crick base pairs (BPs) as they have been perceived; methods based on secondary structure prediction (typically minimum free energy (MFE)) have only had mix success. In this work, we characterized miRNA binding duplexes with a graph model to capture the correlations between pairs of nucleotides of an miRNA and its target sequences. We developed machine learning algorithms to train the graph model to predict the target sites of miRNAs. In particular, because imbalance between positive and negative samples can significantly deteriorate the performance of machine learning methods, we designed a novel method to re-sample available dataset to produce more informative data learning process. We evaluated our model and miRNA target prediction method on human miRNAs and target data obtained from mirTarBase, a database of experimentally verified miRNA-target interactions. The performance of our method in target prediction achieved a sensitivity of 86% with a false positive rate below 13%. In comparison with the state-of-the-art methods miRanda and RNAhybrid on the test data, our method outperforms both of them by a significant margin.

The Observation of the Vein Distribution of a Partial Toe-Transfer Flaps with a Short Vascular Pedicle
Authors: Kobayashi Koichi , Fukasawa Katsuyasu , Masuyama Naoko 
Published: May 2018

Background: When performing partial toe-transfer flaps with a short vascular pedicle, as the flap becomes smaller, the likelihood of securing veins in the flap decreases. The purpose of this study was to clarify how frequently the partial toe-transfer flap with a short pedicle (free vascularized half-big toenail flap) contains veins and elucidate how frequently we can secure the veins with an artery via the first web space approach alone, using the Genial Viewer (a near-infrared light transmission imaging device). Methods: We observed the dorsal vein images of the bilateral big toes of 250 volunteers (male, n = 125; female, n = 125) using the device. We counted the total number of dorsal veins in the big toe, the veins that crossed the margin of the region equivalent to the half-big toenail flap, and the veins that branched off from the fibular side of the flap area. An unpaired Student’s t-test was used for the statistical analyses. Results: All of the dorsal big toes contained veins. The mean number of the veins was 2.3 (range, 1–4). Branched-off veins were observed in the area equivalent to the half-big toenail flap in 496 (99.2%) of the big toes, and the mean number of veins was 1.9 (range, 0–4). In four cases, the region contained no veins (unilaterally). Branched-off veins were observed in the first web space in 440 (88.0%) of the big toes, and the mean number of veins was 0.9 (range, 0–2). Conclusions: The present study indicated high consistency of the veins in partial toe-transfer flaps with a short vascular pedicle and the high possibility of harvesting a flap with only exposing the first web space. In addition, in most cases, the flap will include one or, at most, two veins in the first web space.

Abstract
Aberrant DNA methylation plays a critical role in the development and progression of cancer. Failure to demethylate and to consequently reactivate methylation-silenced genes in cancer contributes to chemotherapeutic resistance, yet the regulatory mechanisms of DNA demethylation in response to chemotherapeutic agents remain unclear. Here, we show that promyelocytic leukemia (PML) recruits ten–eleven translocation dioxygenase 2 (TET2) to regulate DNA modification and cell proliferation in response to chemotherapeutic agents. TET2 was required by multiple chemotherapeutic agents (such as doxorubicin) to prmote 5-hydroxymethylcytosine (5hmC) formation. Stable isotope labeling with amino acids in cell culture, followed by immunoprecipitation–mass spectrometry, identified potential binding partners of TET2, of which PML mostly enhanced 5hmC formation. PML physically bound to TET2 via the PML C-terminal domain and recruited TET2 to PML-positive nuclear bodies. This interaction was disrupted by the PML-RARA t(15;17) mutation, which stems from chromosomal translocation between DNA encoding the C-terminal domain of PML and the retinoic acid receptor alpha (RARA) gene. In response to chemotherapeutic drugs, PML recruited TET2, regulated DNA modification, reactivated methylation-silenced genes, and impaired cell proliferation. Knockout of PML abolished doxorubicin-promoted DNA modification. In addition, PML and TET2 levels positively correlated with improved overall survival in patients with head and neck cancer. These findings shed insight into the regulatory mechanisms of DNA modification in response to chemotherapeutic agents.

Abstract
Improved diagnostics for pancreatic ductal adenocarcinoma (PDAC) to detect the disease at earlier, curative stages and to guide treatments is crucial to progress against this disease. The development of a liquid biopsy for PDAC has proven challenging due to the sparsity and variable phenotypic expression of circulating biomarkers. Here we report methods we developed for isolating specific subsets of extracellular vesicles (EV) from plasma using a novel magnetic nanopore capture technique. In addition, we present a workflow for identifying EV miRNA biomarkers using RNA sequencing and machine-learning algorithms, which we used in combination to classify distinct cancer states. Applying this approach to a mouse model of PDAC, we identified a biomarker panel of 11 EV miRNAs that could distinguish mice with PDAC from either healthy mice or those with precancerous lesions in a training set of n = 27 mice and a user-blinded validation set of n = 57 mice (88% accuracy in a three-way classification). These results provide strong proof-of-concept support for the feasibility of using EV miRNA profiling and machine learning for liquid biopsy.
Significance: These findings present a panel of extracellular vesicle miRNA blood-based biomarkers that can detect pancreatic cancer at a precancerous stage in a transgenic mouse model. Cancer Res; 78(13); 3688–97. ©2018 AACR.

Abstract
The development of myeloid and lymphoid neoplasms related to overexpression of FGFR1 kinases as a result of chromosome translocations depends on the promotion of a stem cell phenotype, suppression of terminal differentiation, and resistance to apoptosis. These phenotypes are related to the stem cell leukemia/lymphoma syndrome (SCLL), which arises through the effects of the activated FGFR1 kinase on gene transcription, which includes miRNA dysregulation. In a screen for miRNAs that are directly regulated by FGFR1, and which stimulate cell proliferation and survival, we identified miR-339-5p, which is highly upregulated in cells carrying various different chimeric kinases. Overexpression of miR-339-5p in SCLL cell types enhances cell survival and inhibition of its function leads to reduced cell viability. miR-339-5p overexpression protects cells from the consequences of FGFR1 inactivation, promoting cell-cycle progression and reduced apoptosis. Transient luciferase reporter assays and qRT-PCR detection of endogenous miR-339-5p expression in stably transduced cell lines demonstrated that BCR-FGFR1 can directly regulate miR-339-5p expression. This correlation between miR-339-5p and FGFR1 expression is also seen in primary human B-cell precursor acute lymphoblastic leukemia. In a screen to identify targets of miR-339-5p, we identified and verified the BCL2L11 and BAX genes, which can promote apoptosis. In vivo, SCLL cells forced to overexpress miR-339-5p show a more rapid onset of disease and poorer survival compared with parental cells expressing endogenous levels of miR-339-5p. Analysis of human primary B-cell precursor ALL shows a significant higher expression of miR339-5p compared with the two cohorts of CLL patient samples, suggesting direct roles in disease progression and supporting the evidence generated in mouse models of SCLL.
Significance: Proapoptiotic genes that are direct targets of miR-339-5p significantly influence promotion and aggressive development of leukemia/lymphomas associated with FGFR1 overexpression. Cancer Res; 78(13); 3522–31. ©2018 AACR.

Abstract
A high rate of disease relapse makes epithelial ovarian cancer (EOC) the leading cause of death among all gynecologic malignancies. These relapses are often due to tumor dormancy. Here we identify the RNA polymerase II transcriptional mediator subunit 12 (MED12) as an important molecular regulator of tumor dormancy. MED12 knockout (KO) induced dormancy of EOC cells in vitro and in vivo, and microarray analysis showed that MED12 KO decreased expression of EGFR. Restoration of EGFR expression in MED12 KO cells restored proliferation. Additionally, MED12 bound to the promoter of EGFR, and correlation studies showed that MED12 expression positively correlated with EGFR expression in EOC patient samples. Clinical data demonstrated that chemotherapy-resistant patients expressed lower levels of MED12 compared with responsive patients. Overall, our data show that MED12 plays an important role in regulating dormancy of EOC through regulation of EGFR.
Significance: MED12 is identified as a novel, important regulator of tumor dormancy in human ovarian cancer. Cancer Res; 78(13); 3532–43. ©2018 AACR.

Published: May 2018

Background:
Smoke-free legislation has been associated with lower rates of cardiovascular disease hospital admissions in ecological studies. However, prior studies lacked detailed information on individual-level factors (eg, sociodemographic and clinical characteristics) that could potentially confound associations. Our objective was to estimate associations of smoke-free policies with incident cardiovascular disease in a longitudinal cohort after controlling for sociodemographics, cardiovascular disease risk factors, and policy covariates.

Methods:
Longitudinal data from 3783 black and white adults in the CARDIA study (Coronary Artery Risk Development in Young Adults; 1995–2015) were linked to state, county, and local 100% smoke-free policies in bars, restaurants, and nonhospitality workplaces by Census tract. Extended Cox regression estimated hazard ratios (HRs) of incident cardiovascular disease associated with time-dependent smoke-free policy exposures. Models were adjusted for sociodemographic characteristics, cardiovascular disease risk factors, state cigarette tax, participant-reported presence of a smoking ban at their workplace, field center, and metropolitan statistical area poverty.

Results:
During a median follow-up of 20 years (68 332 total person-years), 172 participants had an incident cardiovascular disease event (2.5 per 1000 person-years). Over the follow-up period, 80% of participants lived in areas with smoke-free policies in restaurants, 67% in bars, and 65% in nonhospitality workplaces. In fully adjusted models, participants living in an area with a restaurant, bar, or workplace smoke-free policy had a lower risk of incident cardiovascular disease compared with those in areas without smoke-free policies (HR, 0.75, 95% confidence interval, 0.49–1.15; HR, 0.76, 95% confidence interval, 0.47–1.24; HR, 0.54, 95% confidence interval, 0.34–0.86, respectively; HR, 0.58, 95% confidence interval, 0.33–1.00 for living in an area with all 3 types of policies compared with none). The estimated preventive fraction was 25% for restaurant policies, 24% for bar policies, and 46% for workplace policies.

Conclusions:
Consistent with prior ecological studies, these individual-based data add to the evidence that 100% smoke-free policies are associated with lower risk of cardiovascular disease among middle-aged adults.
Audiovisual Integration Varies With Target and Environment Richness in Immersive Virtual Reality

Abstract
We are continually bombarded by information arriving to each of our senses; however, the brain seems to effortlessly integrate this separate information into a unified percept. Although multisensory integration has been researched extensively using simple computer tasks and stimuli, much less is known about how multisensory integration functions in real-world contexts. Additionally, several recent studies have demonstrated that multisensory integration varies tremendously across naturalistic stimuli. Virtual reality can be used to study multisensory integration in realistic settings because it combines realism with precise control over the environment and stimulus presentation. In the current study, we investigated whether multisensory integration as measured by the redundant signals effects (RSE) is observable in naturalistic environments using virtual reality and whether it differs as a function of target and/or environment cue-richness. Participants detected auditory, visual, and audiovisual targets which varied in cue-richness within three distinct virtual worlds that also varied in cue-richness. We demonstrated integrative effects in each environment-by-target pairing and further showed a modest effect on multisensory integration as a function of target cue-richness but only in the cue-rich environment. Our study is the first to definitively show that minimal and more naturalistic tasks elicit comparable redundant signals effects. Our results also suggest that multisensory integration may function differently depending on the features of the environment. The results of this study have important implications in the design of virtual multisensory environments that are currently being used for training, educational, and entertainment purposes.
Regional Climatology of the Northwest Atlantic Ocean: High-Resolution Mapping of Ocean Structure and Change

Published: May 2018

AbstractThe vision of ocean circulation as highly variable and unstable flows generating and reintegrating mesoscale ocean eddies within their surroundings has come into focus over the past several decades based on satellite images and results from eddy-resolving ocean circulation models. Until recently, global ocean climatologies, built as in situ observations mapped onto regular spatial grids, did not reflect this image of ocean circulation because of relatively sparse data coverage. However, in a few key regions of the World Ocean, which are exceptionally data-rich, high-resolution data mapping, as high as 1/10°, has become feasible as a result of the increased volume of available ocean profile data. These new high-resolution ocean data mappings are now matching the details of thermohaline fields generated in eddy-resolving ocean models and, at the near-surface depths, satellite imagery of the ocean surface. The Northwest Atlantic Regional Ocean Climatology—the most advanced example of these new high-resolution regional ocean data mappings—and some of its applications are discussed in this review to provide insights on the advantages of high-resolution regional ocean climatologies for climate studies.
