Abstract
Abstract
Background
The aim was to carry out phase 4 international field-testing of the European Organisation for Research and Treatment of Cancer (EORTC) breast reconstruction (BRECON) module. The primary objective was finalization of its scale structure. Secondary objectives were evaluation of its reliability, validity, responsiveness, acceptability and interpretability in patients with breast cancer undergoing mastectomy and reconstruction.
Methods
The EORTC module development guidelines were followed. Patients were recruited from 28 centres in seven countries. A prospective cohort completed the QLQ-BRECON15 before mastectomy and the QLQ-BRECON24 at 4–8 months after reconstruction. The cross-sectional cohort completed the QLQ-BRECON24 at 1–5 years after reconstruction, and repeated this 2–8 weeks later (test–retest reliability). All participants completed debriefing questionnaires.
Results
A total of 438 patients were recruited, 234 in the prospective cohort and 204 in the cross-sectional cohort. A total of 414 reconstructions were immediate, with a comparable number of implants (176) and donor-site flaps (166). Control groups comprised patients who underwent two-stage implant procedures (72, 75 per cent) or delayed reconstruction (24, 25 per cent). Psychometric scale validity was supported by moderate to high item-own scale and item-total correlations (over 0·5). Questionnaire validity was confirmed by good scale-to-sample targeting, and computable scale scores exceeding 50 per cent, except nipple cosmesis (over 40 per cent). In known-group comparisons, QLQ-BRECON24 scales and items differentiated between patient groups defined by clinical criteria, such as type and timing of reconstruction, postmastectomy radiotherapy and surgical complications, with moderate effect sizes. Prospectively, sexuality and surgical side-effects scales showed significant responsiveness over time (P < 0·001). Scale reliability was supported by high Cronbach's α coefficients (over 0·7) and test–retest (intraclass correlation more than 0·8). One item (finding a well fitting bra) was excluded based on high floor/ceiling effects, poor test–retest and weak correlations in factor analysis (below 0·3), thus generating the QLQ-BRECON23 questionnaire.
Conclusion
The QLQ-BRECON23 is an internationally validated tool to be used alongside the EORTC QLQ-C30 (cancer) and QLQ-BR23 (breast cancer) questionnaires for evaluating quality of life and satisfaction after breast reconstruction.

Abstract
OBJECTIVES Until recently whole genome sequencing (WGS) for mycobacteria has been restricted mostly to the research setting. However, in 2017 Public Health England has implemented WGS for routine mycobacterial identification and susceptibility testing for Mycobacterium tuberculosis. Our objective was to evaluate the impact of this change on the laboratory turnaround times and availability of results. METHODS Over the years 2016 and 2017, the period 1 January to 30 April was selected to represent before and after implementation of WGS. Prior to 2017, line probe assays were used for mycobacterial species identification. Turnaround times for the different steps of the diagnostic process were evaluated for all positive mycobacterial cultures that were sent from our hospital to the Reference Laboratory during the study period. RESULTS A total of 161 positive mycobacterial cultures were sent to the Reference Laboratory. Half of the isolates (n=81/161, 50%) were M. tuberculosis and 80/161 (50%) were non-tuberculous mycobacteria. The median number of workdays for mycobacterial species identification was 1 day (interquartile range (IQR) 1-3) in 2016 and 6 days (IQR 5-7) in 2017, p <0.001. For M. tuberculosis complex, the median time to drug susceptibility testing results, either molecular or phenotypic, was 12 days (IQR 11-18) in 2016 and 8 days (IQR 7-10) in 2017, p <0.001. CONCLUSIONS Routine WGS performed well in this setting for mycobacterial identification and susceptibility testing for M. tuberculosis and decreased time to drug susceptibility testing results. There was an increase in turnaround times for species identification using WGS, when compared with the previous methods.

Abstract
Polysaccharides derived from plant foods are major components of the human diet, with limited contributions of related components from fungal and algal sources. In particular, starch and other storage carbohydrates are the major sources of energy in all diets, while cell wall polysaccharides are the major components of dietary fiber. We review the role of these components in the human diet, including their structure and distribution, their modification during food processing and effects on functional properties, their behavior in the gastrointestinal tract, and their contribution to healthy diets.

Abstract
BACKGROUND Health-related quality of life (HRQL) is often diminished in patients with ulcerative colitis. AIM To evaluate the effects of vedolizumab on HRQL in patients with ulcerative colitis. METHODS Using maintenance phase data from the GEMINI 1 study, an analysis of covariance model was used to calculate mean differences between the vedolizumab and placebo groups in changes from baseline to week 52 for 3 HRQL instruments: The Inflammatory Bowel Disease Questionnaire (IBDQ), 36-Item Short Form Health Survey (SF-36), and EQ-5D. Proportions of patients meeting minimal clinically important difference (MCID) thresholds for changes on these instruments were compared between treatment groups for the overall population and for clinically important subgroups. Concordance between clinical remission and remission defined using IBDQ scores was examined. RESULTS Compared with placebo-treated patients, vedolizumab-treated patients had greater improvements (152-201%) in IBDQ, EQ-5D visual analogue scale (VAS), and EQ-5D utility scores. Greater proportions (6.9-19.9%) of vedolizumab-treated patients than placebo-treated patients met MCID thresholds for all the instruments. Vedolizumab-treated patients with lower baseline disease activity and those without prior tumour necrosis factor (TNF) antagonist failure had greater HRQL improvements. Among 127 patients with clinical remission based on complete Mayo Clinic scores, >80% also had IBDQ remission; >70% of the 150 patients with IBDQ remission demonstrated clinical remission. CONCLUSIONS Vedolizumab therapy was associated with significant improvements in HRQL measures compared with placebo. Benefits were greater in patients with lower disease activity and no prior TNF antagonist failure.

Abstract
AIM To re-assess the content and quality of skeletal surveys performed in the investigation of non-accidental injury following the publication of nationally agreed guidelines produced jointly by the Royal College of Radiologists and the Royal College of Paediatrics and Child Health in 2008. MATERIALS AND METHODS One hundred consecutive skeletal surveys performed in England, which were sent to a tertiary paediatric hospital for a second opinion, were reviewed for their content and quality. The number and type of view was assessed with reference to the 21 recommended views as set out in the College guidance. The quality of each view was assessed and given a score up to a maximum of 10. RESULTS A total of 2,294 radiographic views were acquired, with an average of 22.9 per survey (range 12-21). Fifty-one of the surveys contained all 21 recommended views (previously 15%). The average quality score per view was 9.7/10 (97%), previously 9.7/11 (88%). The commonest cause of reduced quality was the presence of an artefact on the image. CONCLUSION There has been an improvement in the content of skeletal surveys performed in England, which in part may be due to the publication of the national joint Royal College guidance; however, there remain areas for continued development in order to improve practice further.

Abstract
A valproic acid is primarily being used in the treatment of epilepsy is a histone deacetylase inhibitor and it is under investigation for treatment of HIV and various cancer indications. A specific, sensitive and fast bioanalytical LC-MS/MS method was developed with furosemide as an internal standard (IS) and thoroughly validated for the quantitation of valproic acid using turbo ion spray in negative ion mode. The analyte and IS was extracted using protein precipitation. The chromatographic separation of analytes from extracted matrix was achieved using a Chromolith RP 18e (2.0×50 mm) column with a gradient mobile phase comprising of acetonitrile and purified water with acetic acid. The elution of both peaks was achieved within 5.2 min, with retention times of 2.55 min and 1.67 min for valproic acid and IS, respectively. Quantitation of valproic acid was achieved by the pseudo SRM transition pairs (m/z 142.8→m/z 142.8), and SRM transition pair (m/z 328.8 →m/z 204.6) for internal standard.The calibration standards of valproic acid showed linear over a range from 50 to 40 000 ng/mL, with a lower limit of quantitation of 50 ng/mL with accuracy of 3.74% and precision of 5.06%. The bias for inter- and intra-batch assays was 1.24-6.14% and 3.85-11.84%, respectively; while the corresponding precision was 2.56-16.37% and 1.29-11.34%, respectively. The developed method was used to monitor valproic acid levels in clinical samples. Because of higher sensitivity, this method can be used for therapeutic drug monitoring in pediatric subjects.

Abstract
Demand for genitourinary (GU) medicine services is outstripping supply. Improving efficiency can modulate the supply side of the equation, e.g. decreasing the number of clients having to return for their results. This survey explored how clients at two central London GU medicine clinics would like to receive their results and their views were reflected against what was offered by London GU medicine clinics. There was a significant difference between the result delivery services that the clients wanted and what the clinics provided ( P <0.0001, χ2). Of the clients, 92% wanted to know their results regardless of outcome whereas 22% of London clinics would only inform clients of positive results. This study questions the importance and feasibility of patient choice, an important aspect of the National Strategy for Sexual Health and HIV. Clinics may not individually be able to provide choice but between them, they do provide a wide range of alternatives for the client.

Abstract
Plasmodium falciparum dihydroorotate dehydrogenase (PfDHODH) catalyses the fourth reaction of de novo pyrimidine biosynthesis in parasites, and represents an important target for the treatment of malaria. In this study, we describe pharmacophore-based virtual screening combined with docking study and biological evaluation as a rational strategy for identification of novel hits as antimalarial agents. Pharmacophore models were established from known PfDHODH inhibitors using the GALAHAD module with IC50 values ranging from 0.033 μM to 142 μM. The best pharmacophore model consisted of three hydrogen bond acceptor, one hydrogen bond donor and one hydrophobic features. The pharmacophore models were validated through receiver operating characteristic and Günere-Henry scoring methods. The best pharmacophore model as a 3D search query was searched against the IBS database. Several compounds with different structures (scaffolds) were retrieved as hit molecules. Among these compounds, those with a QFIT value of more than 81 were docked in the PfDHODH enzyme to further explore the binding modes of these compounds. In silico pharmacokinetic and toxicities were predicted for the best docked molecules. Finally, the identified hits were evaluated in vivo for their antimalarial activity in a parasite inhibition assay. The hits reported here showed good potential to become novel antimalarial agents.

Abstract
AIM C-reactive protein (CRP) has proven to be a useful adjunct in early diagnosis of anastomotic leak (AL) after colorectal surgery. It would be of considerable value to examine whether modality of surgery has influence upon postoperative CRP serum levels and their predictive value in the diagnosis of AL. METHODS All patients undergoing elective colorectal surgery with anastomosis were enrolled into a prospective database between 2011 and 2014. AL was defined with strict operative and radiological criteria. Outcomes between open and laparoscopic resections were assessed statistically and Receiver Operating Characteristic (ROC) curve analysis performed. RESULTS Seven hundred twenty-seven patients with an intestinal anastomosis were identified including 468 laparoscopic procedures (468/727; 64 %). There were 58 anastomotic leaks (58/727; 7.9 %) of which 29 (6.2 %) were laparoscopic and 29 (11.2 %) were open. Mean CRP levels were significantly higher in patients after open surgery compared with laparoscopic both with AL (p = 0.013), and without (p = 0.02). ROC curve analysis revealed postoperative day 3 (cut-off CRP 209) and day 4 (cut-off CRP 123.5) to be most predictive of leak in the open group with an area under the curve (AUC) 0.794 (sensitivity 80 %, specificity 80 %) and AUC 0.806 (sensitivity 94 %, specificity 60 %), respectively. In the laparoscopic group, day 2 proved to be the most accurate day for detection of leak with a cut-off CRP of 146.5 showing 75 % sensitivity and a 70 % specificity (AUC 0.766). CONCLUSION CRP levels are higher after open surgery compared with laparoscopic surgery, both with and without AL. AL generates a significant detectable increase in CRP within 2-4 days after surgery.

Abstract
INdian Test Facility (INTF) is envisaged to characterize ITER diagnostic neutral beam system and to establish the functionality of its eight inductively coupled RF plasma driver based negative hydrogen ion source and its beamline components. The beam quality mainly depends on the ion source performance and therefore, its diagnostics plays an important role for its safe and optimized operation. A number of diagnostics are planned in INTF to characterize the ion source performance. Negative ions and its cesium contents in the source will be monitored by optical emission spectroscopy (OES) and cavity ring down spectroscopy. Plasma near the extraction region will be studied using standard electrostatic probes. The beam divergence and negative ion stripping losses are planned to be measured using Doppler shift spectroscopy. During initial phase of ion beam characterization, carbon fiber composite based infrared imaging diagnostics will be used. Safe operation of the beam will be ensured by using standard thermocouples and electrical voltage-current measurement sensors. A novel concept, based on plasma density dependent plasma impedance measurement using RF electrical impedance matching parameters to characterize the RF driver plasma, will be tested in INTF and will be validated with OES data. The paper will discuss about the overview of the complete INTF diagnostics including its present status of procurement, experimentation, interface with mechanical systems in INTF, and integration with INTF data acquisition and control systems.

Abstract
Defining mechanisms that generate intratumour heterogeneity and branched evolution may inspire novel therapeutic approaches to limit tumour diversity and adaptation. SETD2 (Su(var), Enhancer of zeste, Trithorax-domain containing 2) trimethylates histone-3 lysine-36 (H3K36me3) at sites of active transcription and is mutated in diverse tumour types, including clear cell renal carcinomas (ccRCCs). Distinct SETD2 mutations have been identified in spatially separated regions in ccRCC, indicative of intratumour heterogeneity. In this study, we have addressed the consequences of SETD2 loss-of-function through an integrated bioinformatics and functional genomics approach. We find that bi-allelic SETD2 aberrations are not associated with microsatellite instability in ccRCC. SETD2 depletion in ccRCC cells revealed aberrant and reduced nucleosome compaction and chromatin association of the key replication proteins minichromosome maintenance complex component (MCM7) and DNA polymerase δ hindering replication fork progression, and failure to load lens epithelium-derived growth factor and the Rad51 homologous recombination repair factor at DNA breaks. Consistent with these data, we observe chromosomal breakpoint locations are biased away from H3K36me3 sites in SETD2 wild-type ccRCCs relative to tumours with bi-allelic SETD2 aberrations and that H3K36me3-negative ccRCCs display elevated DNA damage in vivo. These data suggest a role for SETD2 in maintaining genome integrity through nucleosome stabilization, suppression of replication stress and the coordination of DNA repair.

Abstract
RhoGTPases organize the actin cytoskeleton to generate diverse polarities, from front-back polarity in migrating cells to dendritic spine morphology in neurons. For example, RhoA through its effector kinase, RhoA kinase (ROCK), activates myosin II to form actomyosin filament bundles and large adhesions that locally inhibit and thereby polarize Rac1-driven actin polymerization to the protrusions of migratory fibroblasts and the head of dendritic spines. We have found that the two ROCK isoforms, ROCK1 and ROCK2, differentially regulate distinct molecular pathways downstream of RhoA, and their coordinated activities drive polarity in both cell migration and synapse formation. In particular, ROCK1 forms the stable actomyosin filament bundles that initiate front-back and dendritic spine polarity. In contrast, ROCK2 regulates contractile force and Rac1 activity at the leading edge of migratory cells and the spine head of neurons; it also specifically regulates cofilin-mediated actin remodeling that underlies the maturation of adhesions and the postsynaptic density of dendritic spines.

Abstract
This paper describes the synthesis, early process development, salt selection strategies and pre clinical evaluation of novel, potent and selective CB1 antagonist, 8-Chloro-1-(2,4-dichloro-phenyl)-4,5-dihydro-1H-6-oxa-1,2-diaza-benzo[e]azulene-3-carboxylic acid piperidin-1-ylamide 1. The CB1 antagonism of compound 1 is also confirmed by reversal of CB1 agonist-induced hypothermia in Swiss albino mice. The process for the preparation of the compound 1 as a crystalline solid is also described. The crystalline form of the compound is found to be low bioavailable, therefore attempts have been made to improve its bioavailability through polymorphic transformation and salt formation. None of the salts prepared were found to be suitable for further development. The amorphous form of the compound 1 is found to be better suited. In vivo efficacy study of the amorphous form of compound 1 in 5% sucrose solution intake model in female Zucker fa/fa rats at single oral dose of 10 mg/kg demonstrates better reduction in the sucrose solution consumption than the corresponding crystalline form. The plasma concentration Cmax at AUC exposure of the amorphous form of the compound 1 is significantly improved and better than the Cmax of the corresponding crystalline form of the compound 1. On the basis of the efficacy, pharmacokinetic and toxicological evaluations, the compound 1 in the amorphous form is selected as a pre-clinical lead candidate.

Abstract
Hepatic portal venous gas (HPVG) is a rare disease entity. It is an ominous finding, usually, associated with intraabdominal ischemic necrosis. It frequently requires emergent surgical intervention. Herein, we present a case of a patient who complained of intense abdominal pain, with radiographic findings of HPVG as a result of cocaine-induced vascular insufficiency. After 5 h of nonoperative and conservative management, the HPVG spontaneously resolved. The patient clinically improved and was discharged home in a stable condition.
