Abstract
BACKGROUND This study aimed to establish whether histology tonsillectomy is justified for unilateral tonsil enlargement. METHODS A retrospective review was conducted of histology tonsillectomies in three health organisations over five years, with strict exclusion criteria, focusing on benign-appearing unilateral tonsil enlargement. RESULTS Ninety paediatric and 233 adult cases were included. No paediatric cases and five adult cases of malignancy were detected. All malignant cases presented with other symptoms. Using binary logistic regression, a history of rapid unilateral tonsil enlargement was the only factor found to be significantly associated with malignant outcome. Thirty-three per cent of subjectively larger tonsils were smaller on post-operative histological measurement. Of the cases, 12.1 per cent re-presented with post-tonsillectomy bleeding. CONCLUSION The authors recommend avoiding histology tonsillectomy for unilateral tonsil enlargement unless 'red flag' signs of malignancy are present, with particular attention to rapid unilateral tonsil enlargement. This study demonstrated discrepancy between clinical examination findings and true tonsil asymmetry; there may be a role for cross-sectional imaging prior to histology tonsillectomy in high-risk patients.

Abstract
AIM This study aimed to: (i) calculate personal financial costs associated with urgent dental attendance; and (ii) investigate the pain-related disability and quality of life impact of dental conditions which result in urgent dental attendance. METHODOLOGY Data were collected from those presenting with urgent dental conditions to an out-of-hours dental service, a dental emergency clinic and five primary care general dental practices across North-East England. A pre-operative questionnaire explored the impact of urgent dental conditions on oral health-related quality of life (OHRQoL) using Oral Health Impact Profile-14 (OHIP-14) and modified Graded Chronic Pain Scale (GCPS). OHIP-14 yields a maximum score of 56, with a higher score indicating a lower OHRQoL. Personal financial costs were summed to provide a total. These included travel, appointment fees, childcare costs, medication use and time away from work. Data were analysed using one-way ANOVA and multivariable modelling. RESULTS In total, 714 participants were recruited. Mean OHIP-14 score was 25.73; 95% CI [24.67, 26.79], GCPS CPI was 71.69; 95% CI [70.09, 73.28] and GCPS interference was 49.56; 95% CI [47.24, 51.87]. Symptomatic irreversible pulpitis was the most frequently managed dental emergency and was associated with the highest mean OHIP-14 score (31.67; 95% CI [30.20, 33.15]). The mean personal financial cost of urgent dental care was £85.81; 95% CI [73.29, 98.33]. Differences in travel time (F[2, 691] = 10.24, p<.001), transport costs (F[2, 698] = 4.92, p=.004), and appointment time (F[2, 74] = 9.40, p<.001) were significant between patients attending an out-of-hours dental service, dental emergency clinic and dental practices for emergency care, with a dental emergency clinic being associated with the highest costs and dental practices the lowest. CONCLUSIONS Diseases of the pulp and associated periapical disease were the most common reason for patients to present for urgent dental care and were the most impactful in terms of OHRQoL and pain in the present sample. Personal financial costs are significant from urgent dental conditions, with centralised services increasing the burden to patients of attending appointments.

Abstract
Here, we provide an updated set of guidelines for naming genes in wheat that has been endorsed by the wheat research community. The last decade has seen a proliferation in genomic resources for wheat, including reference- and pan-genome assemblies with gene annotations, which provide new opportunities to detect, characterise, and describe genes that influence traits of interest. The expansion of genetic information has supported growth of the wheat research community and catalysed strong interest in the genes that control agronomically important traits, such as yield, pathogen resistance, grain quality, and abiotic stress tolerance. To accommodate these developments, we present an updated set of guidelines for gene nomenclature in wheat. These guidelines can be used to describe loci identified based on morphological or phenotypic features or to name genes based on sequence information, such as similarity to genes characterised in other species or the biochemical properties of the encoded protein. The updated guidelines provide a flexible system that is not overly prescriptive but provides structure and a common framework for naming genes in wheat, which may be extended to related cereal species. We propose these guidelines be used henceforth by the wheat research community to facilitate integration of data from independent studies and allow broader and more efficient use of text and data mining approaches, which will ultimately help further accelerate wheat research and breeding.

Abstract
The Indigenous Cultural Identity of Research Authors Standard (ICIRAS) is based on a gap in research publishing practice where Indigenous peoples' identity is not systematically and rigorously recognised in rural health research publications. There are widespread reforms, in different research areas, to counter the reputation of scientific research as a vehicle of racism and discrimination. Reflecting on these broader movements, the editorial teams of three rural health journals - Rural and Remote Health, the Australian Journal of Rural Health, and the Canadian Journal of Rural Medicine - adopted a policy of 'Nothing about Indigenous Peoples, without Indigenous Peoples'. This meant changing practices so that Indigenous Peoples' identity could be embedded in authorship credentials - such as in the byline. An environmental scan of literature about the inclusion of Indigenous Peoples in research revealed many ways in which editorial boards of journals could improve their process to signal to readers that Indigenous voices are included in rural health research publication governance. Improving the health and wellbeing of Indigenous peoples worldwide requires high-quality research evidence. This quality benchmark needs to explicitly signal the inclusion of Indigenous authors. The ICIRAS is a call to action for research journals and institutions to rigorously improve research governance and leadership to amplify the cultural identity of Indigenous peoples in rural health research.

Abstract
AbstractBrassica napus (canola/rapeseed) race specific resistance genes against blackleg disease, caused by the ascomycete fungus Leptosphaeria maculans, have been commonly used in canola breeding. To date; LepR3, Rlm2 and Rlm9 R genes against L. maculans have been cloned from B. napus. LepR3 and Rlm2 are Receptor Like Proteins (RLP) and the recently reported Rlm9 is a Wall Associated Kinase-Like (WAKL) protein. Rlm9 located on chromosome A07 is closely linked with Rlm3, Rlm4, RLm7 genes. Recognition of AvrLm5-9 and AvrLm3 by their corresponding Rlm9 and Rlm3 proteins is masked in the presence of AvrLm4-7. Here we report cloning of Rlm4 and Rlm7 by generating genome sequence of the doubled haploid (DH) B. napus cv Topas DH16516 introgression lines Topas-Rlm4 and Topas-Rlm7. Candidate Rlm4 and Rlm7 genes were identified form the genome sequence and gene structures were determined by mapping RNA-sequence reads, generated from infected cotyledon tissues, to the genome of Topas-Rlm4 and Topas-Rlm7. Rlm4 and Rlm7 genomic constructs with their native promoters were transferred into the blackleg susceptible B. napus cv Westar N-o-1. Complementation of resistance response in the transgenic Westar:Rlm4 and Westar:Rlm7 that were inoculated with L. maculans transgenic isolates 2367:AvrRlm4-7 or 2367:AvrLm7 confirmed the function of Rlm4 and Rlm7 genes. Wild type L. maculans isolate 2367 that does not contain AvrLm4-7 or AvrLm7, and transgenic 2367:AvrLm3 and 2367:AvrLm5-9 did not induce resistance proving the specificity of Rlm4 and Rlm7 response. Rlm4 and Rlm7 alleles are also allelic to Rlm9. Rlm4 and Rlm7 genes encode WAKL proteins. Comparison of highly homologous sequences of Rlm4 and Rlm7 with each other and with the sequence of additional alleles, using whole genome sequencing of additional 128 lines, identified a limited number of point mutation located within the predicted extracellular receptor domains.

Abstract
Data sources Medline/PubMed, Web of Science, Scopus and Cochrane Library databases. Grey literature searches (OpenGrey, ProQuest databases), hand searches in the reference list of eligible studies and relevant journals.Study selection Randomised controlled trials (RCTs) and prospective clinical trials (PCTs) with direct comparisons between metal posts (MPs) and fibre posts (FPs). Trials contained a minimum of ten patients and endodontically treated permanent teeth that had received either single crowns or fixed partial dentures (bridges) and followed up for a minimum of one year. The primary outcome compared the difference in failure rates between FPs and MPs, with subgroup analysis comparing location (anterior/posterior), type of MP (cast post core/preformed MP) and most frequent modes of failure (debond/root fracture).Data extraction and synthesis Study selection, data collection and risk of bias assessments were completed independently by two reviewers. Disagreements were discussed with a third reviewer to reach a consensus. The risk of bias was evaluated using the Cochrane risk of bias tool (RCTs) or the ROBINS-I tool (PCTs). The quality of responses was assessed using the Grading of Recommendations Assessment, Development And Evaluation (GRADE) approach. The meta-analysis (MA) was performed using the Mantel-Haenszel method. Trial heterogeneity was assessed using random- and fixed-effects models. Inter-examiner agreement during the database search and study selection process was checked using the kappa statistic.Results After duplicates were removed, 1,026 articles were assessed and screened by title and abstract. Of these, 21 articles underwent full-text evaluation, with ten articles meeting the eligibility criteria. Eligible studies included six RCTs and four PCTs. A total of 844 endodontically treated teeth (ETT) were restored with intra-radicular posts in 704 participants. Four hundred and fifty-three ETT were restored with FPs and 391 with MPs. The mean age of participants was 42.7 (33.95-55.45) years, with a mean follow-up period of 50.95 (12-154) months. Most studies reported failures during the follow-up period, but the MA revealed no significant difference between FPs and MPs in terms of failure rates (P = 0.39; RR: 0.82 mm; CI: 0.52-1.29). Sub-analysis showed no difference in failure rates between anterior and posterior regions and no difference when comparing FPs to cast post and core vs prefabricated MPs. Root fractures and post debondings were the most common modes of failure, but within these failures, no difference was observed between FPs and MPs.Conclusions No evidence was identified for a difference in failure rates between FPs and MPs. This was independent of the type of MP and position within the arch. Reporting of RCTs and PCTs was variable and further high-quality studies are needed.

Abstract
Background There is a high prevalence of COVID-19 in university-age students, who are returning to campuses. There is little evidence regarding the feasibility of universal, asymptomatic testing to help control outbreaks in this population. This study aimed to pilot mass COVID-19 testing on a university research park, to assess the feasibility and acceptability of scaling up testing to all staff and students. Methods This was a cross-sectional feasibility study on a university research park in the East of England. All staff and students (5625) were eligible to participate. All participants were offered four PCR swabs, which they self-administered over two weeks. Outcome measures included uptake, drop-out rate, positivity rates, participant acceptability measures, laboratory processing measures, data collection and management measures. Results 798 (76%) of 1053 who registered provided at least one swab; 687 (86%) provided all four; 792 (99%) of 798 who submitted at least one swab had all negative results and 6 participants had one inconclusive result. There were no positive results. 458 (57%) of 798 participants responded to a post-testing survey, demonstrating a mean acceptability score of 4.51/5, with five being the most positive. Conclusions Repeated self-testing for COVID-19 using PCR is feasible and acceptable to a university population.

Abstract
Abstract
Aims
Patients with heart failure with preserved ejection fraction (HFpEF) are usually older and multi-morbid and diagnosis can be challenging. The aims of this cohort study were to confirm diagnosis of HFpEF in patients with possible HFpEF recruited from primary care, to compare characteristics and health status between those with and without HFpEF, and to determine factors associated with health status in patients with HFpEF.
Methods
Patients with presumed HFpEF were recruited from primary care practices and underwent clinical assessment and diagnostic evaluation as part of a longitudinal cohort study. Health status was measured by Montreal Cognitive Assessment (MOCA), 6-minute walk test, symptoms, and the Kansas City Cardiomyopathy Questionnaire (KCCQ), and quality of life (QoL) by EQ-5D-5L visual analogue scale (VAS).
Results
151 patients (mean age 78.5±8.6 years, 40% women, mean EF 56% + 9.4) were recruited and 93 (61.6%) were confirmed HFpEF (those without HFpEF had other HF and cardiac diagnoses). Patients with and without HFpEF did not differ by age, MOCA, blood pressure, heart rate, NYHA class, proportion with atrial fibrillation, Charlson Comorbidity Index, or NT-ProBNP levels. Patients with HFpEF were more likely to be women, overweight or obese, frail, and to be more functionally impaired by 6 minute walk distance and gait speed than those without. Although not statistically significant, patients with HFpEF had clinically significant differences (>5 points) on the physical limitations, symptom burden and clinical summary subscales of the KCCQ, but did not differ by other subscales or by EQ-5D-5L VAS (70±17 vs 73±19, p=0.385). More patients with HFpEF reported daytime dyspnoea (63% vs 46%, p=0.035) and fatigue (81% vs 61%, p=0.008), but not other symptoms compared to those without HFpEF. For both groups BMI was moderately negatively correlated with KCCQ subscale scores, and 6 minute walk distance was positively correlated with KCCQ subscales.
Conclusions
Nearly 40% were not confirmed as HFpEF indicating the challenges of diagnosis. Patients with confirmed HFpEF differed by sex, overweight/obesity, frailty, functional impairment, and symptoms but not by age or comorbidities from those without HFpEF. These differences were reflected in some subscale scores of the KCCQ, but not how patients reported their quality of life on the KCCQ QoL subscale and EQ-5D-5L VAS. Older patients with HFpEF reported relatively high QoL despite poor health status by functional impairment, frailty and symptoms.

Abstract
BACKGROUND Chronic bone marrow lesions (BML) in the weight-bearing portions of the knee are often associated with symptomatic degenerative arthritis resulting in pain and dysfunction. Injection of bone substitute material like calcium phosphate has been described. Whilst some studies have reported encouraging results others have shown limited benefit of this technique. AIM The aim was to collate the available evidence on the injection of calcium phosphate and systematically evaluate the results to answer the questions encountered in clinical decision making: (1) does it provide effective long-lasting pain relief to avoid further surgical intervention? (2) which factors (patient/surgical) significantly influence the outcome? and (3) does it adversely affect the outcomes of subsequent arthroplasty? METHODS A literature search was performed to identify the studies describing the clinical outcomes of calcium phosphate injection for treatment of BML. We evaluated the reported clinical outcomes with respect to pain, function and complications. Isolated case reports and studies with no objective assessment of clinical outcomes were excluded. RESULTS We noted 46 articles in the current literature of which 8 described clinical outcomes of calcium phosphate injection. Mean (plus/minus SD) score on the visual analog scale (VAS) has been reported to improve from 7.90 (± 0.38) to 2.76 (± 0.90), whereas the International Knee Documentation Committee (IKDC) score improved from 30.5 (SD not reported (NR)) to 53.0 (SD NR). Pre and post procedure Short form survey (SF-12) scores were 29.8 (SD NR) and 36.7 (SD NR), respectively. In one study, scores on the Tegner Lysholm knee scoring scale improved in 12 out of 22 patients, whereas the remainder had no change in symptoms. Extravasation of calcium phosphate into the joint was the most common complication, whereas no adverse effect has been reported on subsequent arthroplasty. CONCLUSION Limited data from the published studies would suggest that calcium phosphate injection of BML may potentially improve pain and function. However, no evidence is currently available to clearly identify patient/surgical factors that may influence the long-term outcomes of this procedure. Hence pragmatic, prospective studies with stratified patient cohorts and robust reporting of outcome measures are essential to improve the understanding of the indications and clinical effectiveness of this novel procedure.

Abstract
Abstract
Introduction: Anxiety toward dental treatment can lead to preventable morbidity, most notably oral pain and infection. This is of concern to the UK Armed Forces (UK AF), as dental care may not be immediately accessible during deployments and exercises, necessitating aeromedical evacuation. Current Defence Policy states that serving UK AF personnel requiring sedation to tolerate routine dental treatment are to have their Joint Medical Employment Standard (JMES) reviewed to restrict their deployability and employability. This article explores current sedation delivery, dentist opinion, and adherence to policy. Materials and Methods: The total number and type of intravenous (IV) sedation appointments over a 6-month period was assessed using surgical logbooks. Questionnaires were sent to all dentists in primary care responsible for treating military patients to ascertain their attitudes toward the requirement for sedation in support of recruitment and deployability. Ten-year retrospective data analyses were used to identify current trends in sedation use in the UK AF. Results: Responses were received from 117/137 (85%) dentists. All of the responding Civilian Dental Practitioners felt that there was a requirement for IV sedation in contrast to the Royal Navy (RN), where over a quarter (28%) disagreed. The majority, 48 (81%), of Army dentists felt that military patients unable to tolerate routine treatment under local anesthesia alone should not deploy on operations, compared with 7 (63%) of their civilian counterparts. Overall, 72 (62%) respondents felt that patients unable to tolerate routine treatment without sedation should not be recruited. Conclusions: Civilian Dental Practitioners in the sample indicated that they were less likely to recommend a patient for JMES review, less likely to prevent patients from deploying and less likely to believe that individuals requiring sedation for routine treatment should not be recruited into the UK AF. These attitudes are contrary to current Defence direction and could increase the risk of UK AF personnel experiencing morbidity on deployment requiring aeromedical evacuation. Over the longer term, civilianization of Defence dentistry is likely to reduce collective operational experience and Defence must ensure that clinicians understand the management of anxious patients in the military context and their responsibilities in relation to JMES. Furthermore, policy limiting the recruitment of personnel with significant dental anxiety is not being robustly adhered to. Based on the number of dental procedures undertaken under IV sedation in the UK AF, consistent application of this policy would not affect recruitment at an organizational level, but would limit the risk of deploying these personnel. Further work is required to understand dental anxiety within the UK Armed Forces so that the operational morbidity risks can be quantified and provision appropriately planned.

Abstract
Abstract
Background
Current clinical specialities, guidelines and quality of care metrics are organised around single diseases and treatments of multiple conditions are rarely coordinated, resulting in insufficient or even conflicting care. This study uses large scale English general practice (GP) records to identify and characterise clusters of patients based on their multimorbidity to allow better design of health services and highlight groups that require additional interventions.
Methods
This is a retrospective cohort study that includes multimorbid adult patients (N = 113,211), from a random sample of 391,669 English patients with valid GP records in 2012 where 38 long-term conditions were defined. Latent class analysis, stratified by age groups, was used to identify multimorbidity clusters. Class solutions are validated and associations between multimorbidity clusters, patient characteristics, public health service utilisation and mortality are assessed.
Results
Poor socioeconomic status is associated with clusters with higher service use and mortality risk. Physical-mental health co-morbidity is a major component of multimorbidity across all age strata. The clusters with highest age-stratified mortality risk in under 65 year olds were linked to alcohol and substance misuse, whereas in over 65 year olds they were linked to cardiovascular disease. The largest cluster in the 85+ years strata (58%) has the lowest number of morbidities, a low degree of service use and mortality. Consistency was seen across identification and validation data.
Conclusions
We find a clear distinction between morbidity clusters, both in the prevalence of long term conditions within them, and in their associations with outcomes (service use and mortality). Specific health services and interventions might be more effective when targeted on the distinct types of multimorbidity we have identified, with a particular focus on the morbidity clusters associated with the worst patient outcomes.
Key messages
The first study to derive age stratified multimorbidity clusters from a large GP record system, whose patients are representative of the English population. Knowledge about particularly dangerous clusters of multimorbidity, such as those involving alcohol and drug use in 18–64 years old, and cardiovascular disease in those 65 years or older.

Abstract
The most common treatment for patients with sickle cell disease (SCD) is the chemotherapeutic hydroxyurea, a therapy with pleiotropic effects, including increasing fetal hemoglobin (HbF) in red blood cells and reducing adhesion of white blood cells to the vascular endothelium. Hydroxyurea has been proposed to mediate these effects through a mechanism of increasing cellular cGMP levels. An alternative path to increasing cGMP levels in these cells is through the use of phosphodiesterase-9 inhibitors that selectively inhibit cGMP hydrolysis and increase cellular cGMP levels. We have developed a novel, potent and selective phosphodiesterase-9 inhibitor (IMR-687) specifically for the treatment of SCD. IMR-687 increased cGMP and HbF in erythroid K562 and UT-7 cells and increased the percentage of HbF positive erythroid cells generated in vitro using a two-phase liquid culture of CD34+ progenitors from sickle cell blood or bone marrow. Oral daily dosing of IMR-687 in the Townes transgenic mouse SCD model, increased HbF and reduced red blood cell sickling, immune cell activation and microvascular stasis. The IMR-687 reduction in red blood cell sickling and immune cell activation was greater than that seen with physiological doses of hydroxyurea. In contrast to other described phosphodiesterase-9 inhibitors, IMR-687 did not accumulate in the central nervous system, where it would inhibit phosphodiesterase-9 in neurons, or alter rodent behavior. IMR-687 was not genotoxic or myelotoxic and did not impact fertility or fetal development in rodents. These data suggest that IMR-687 may offer a safe and effective oral alternative for hydroxyurea in the treatment of SCD.

Abstract
Abstract
Background: Endocrine therapy is used in estrogen receptor (ER)-positive breast cancers, however, 25% of these patients are at risk of distant relapse and the development of acquired endocrine resistance. Recently mutations in the ER gene (ESR1) have been validated to be acquired during the development of endocrine resistance. The most frequent ESR1 mutation, Y537S, promotes ligand-independent ER activity and emerges subclonally during aromatase inhibitor treatment. In this study, we examined the effects of the Y537S ESR1 mutation on cell cycle signaling and therapeutic response to a novel checkpoint inhibitor.
Material and Methods: MCF-7 cells expressing the Y537S ESR1 mutation were generated by CRISPR-Cas9 knock-in techniques. Cells were incubated in steroid deprived conditions. Cell cycle analysis and apoptosis were examined by flow cytometry annnexin-V assays. Proliferation was analyzed by BrdU incorporation. Cell cycle checkpoint kinases were examined by western blot analysis. Cell growth was analyzed using soft agar and MTT assays. Replication stress was identified by RPA32 and gamma-H2AX foci formation assay. For in vivo studies, MCF-7 ESR1 Y537S mutant cells were injected into female athymic nude mice with 17β-estradiol (E2) supplemented water. When tumors reached 350 mm3, tamoxifen (20 mg/kg; s.c.; three times a week), fulvestrant (200 mg/kg; s.c; once a week) and/or PF477736 Chk1 inhibitor (7.5 mg/kg; i.p.; twice a day and twice a week) was treated without E2.
Results: ESR1 Y537S mutant cells accumulated approximately 5 fold in S phase and 1.7 fold in G2/M phase compared to control cells in estrogen-deprived (ED) conditions. BrdU incorporation also increased about 2.5-fold, however, apoptosis was decreased about 60 % compared with wild-type ER parental cells. ESR1 Y537S mutant cells induced significant replication stress, showing increased RPA32 foci together with increased gamma H2AX foci, a marker of DNA double-stranded breaks. ChIP-seq analysis revealed binding sites on ATR and CHEK1 genomic locations. ATR/Chk1-mediated checkpoint signaling was activated in ESR1 Y537S mutant cells, and was repressed with fulvestrant, tamoxifen, or ESR1 siRNA treatment. The Chk1 inhibitor, PF477736, sensitized MCF-7 expressing the ESR1 Y537S mutation to endocrine treatments such as fulvestrant, tamoxifen, and the ER degrader AZD9496 in cell proliferation assays. In MCF-7 ESR1 Y537S mutant xenograft and patient derived mouse models, tamoxifen treatment combined with the Chk1 inhibitor PF477736 repressed primary xenograft tumor doubling times (P=0.038, Wilcoxon test). Treatment of mutant tumors with PF477736 together with fulvestrant significantly inhibited the frequency of distant lung metastases by 80% (P=0.0031, t-test), suggesting that these combinations may be useful in second line treatment of metastatic breast cancer patients resistant to endocrine therapies.
Conclusion: These preclinical results suggest that ESR1 mutant tumors have a therapeutic vulnerability to combination endocrine therapy with cell cycle checkpoint kinase inhibitors. These data demonstrate that this new therapeutic approach may be useful to restore endocrine sensitivity in metastatic breast cancer patients with ESR1 mutation driven-endocrine resistance.

Abstract
Salinity is a major constraint for intrinsically salt sensitive grain legume chickpea. Chickpea exhibits large genetic variation amongst cultivars, which show better yields in saline conditions but still need to be improved further for sustainable crop production. Based on previous multi-location physiological screening, JG 11 (salt tolerant) and ICCV 2 (salt sensitive) were subjected to salt stress to evaluate their physiological and transcriptional responses. A total of ~480 million RNA-Seq reads were sequenced from root tissues which resulted in identification of 3,053 differentially expressed genes (DEGs) in response to salt stress. Reproductive stage shows high number of DEGs suggesting major transcriptional reorganization in response to salt to enable tolerance. Importantly, cationic peroxidase, Aspartic ase, NRT1/PTR, phosphatidylinositol phosphate kinase, DREB1E and ERF genes were significantly up-regulated in tolerant genotype. In addition, we identified a suite of important genes involved in cell wall modification and root morphogenesis such as dirigent proteins, expansin and casparian strip membrane proteins that could potentially confer salt tolerance. Further, phytohormonal cross-talk between ERF and PIN-FORMED genes which modulate the root growth was observed. The gene set enrichment analysis and functional annotation of these genes suggests they may be utilised as potential candidates for improving chickpea salt tolerance.

Abstract
Pretibial lacerations are a common cause of presentation to accident and emergency departments. The management of these wounds is contentious with a variation in practise between individual institutions. We present the case of a 49-year-old female with a background of pulmonary atresia and associated pulmonary hypertension, who underwent successful outpatient negative pressure wound therapy (NPWT) for three pretibial lacerations. We would propose that this therapy is an effective option for the management of these wounds in independently mobile patients who are at high-risk when under anaesthetic.

Abstract
Results from this study of the white shark Carcharodon carcharias include measurements obtained using a novel photographic method that reveal significant differences between the sexes in the relationship between tooth cuspidity and shark total length, and a novel ontogenetic change in male tooth shape. Males exhibit broader upper first teeth and increased distal inclination of upper third teeth with increasing length, while females do not present a consistent morphological change. Substantial individual variation, with implications for pace of life syndrome, was present in males and tooth polymorphism was suggested in females. Sexual differences and individual variation may play major roles in ontogenetic changes in tooth morphology in C. carcharias, with potential implications for their foraging biology. Such individual and sexual differences should be included in studies of ontogenetic shift dynamics in other species and systems.

Abstract
The Brassica napus Illumina array provides genome-wide markers linked to the available genome sequence, a significant tool for genetic analyses of the allotetraploid B. napus and its progenitor diploid genomes. A high-density single nucleotide polymorphism (SNP) Illumina Infinium array, containing 52,157 markers, was developed for the allotetraploid Brassica napus. A stringent selection process employing the short probe sequence for each SNP assay was used to limit the majority of the selected markers to those represented a minimum number of times across the highly replicated genome. As a result approximately 60 % of the SNP assays display genome-specificity, resolving as three clearly separated clusters (AA, AB, and BB) when tested with a diverse range of B. napus material. This genome specificity was supported by the analysis of the diploid ancestors of B. napus, whereby 26,504 and 29,720 markers were scorable in B. oleracea and B. rapa, respectively. Forty-four percent of the assayed loci on the array were genetically mapped in a single doubled-haploid B. napus population allowing alignment of their physical and genetic coordinates. Although strong conservation of the two positions was shown, at least 3 % of the loci were genetically mapped to a homoeologous position compared to their presumed physical position in the respective genome, underlying the importance of genetic corroboration of locus identity. In addition, the alignments identified multiple rearrangements between the diploid and tetraploid Brassica genomes. Although mostly attributed to genome assembly errors, some are likely evidence of rearrangements that occurred since the hybridisation of the progenitor genomes in the B. napus nucleus. Based on estimates for linkage disequilibrium decay, the array is a valuable tool for genetic fine mapping and genome-wide association studies in B. napus and its progenitor genomes.

Abstract
OBJECTIVE The objective of the study is to report a systematic review of what is currently known about the experience of cancer treatment and cancer treatment in adults with dementia. METHODS The analytic plan and inclusion/exclusion criteria were specified in advance of the search process in a protocol. Searches were conducted in MEDLINE, CINAHL, PsycINFO and the Cochrane Library for publications about people with cancer and a pre-existing dementia. Limits were English language; 2000 to 12/2015; adults; >18 years old. The search identified 5214 titles and abstracts that were assessed against eligibility criteria and 101 were selected for full-text examination by two researchers who agreed inclusion of nine papers, extracted data independently then conducted a content analysis and narrative synthesis. RESULTS Nine studies conducted in four resource rich countries were included in the review. These studies evidence that when compared with other cancer patients, those with dementia are diagnosed at a later stage, receive less treatment, are more likely to experience complications from treatment and have poorer survival. The experience of supportive care and preferences of people with dementia receiving cancer services and cancer treatment have not been investigated. Research into how the cancer team manage the particular needs of people with dementia and their family members has been limited to one study that reported how a cancer team managed the particular needs of seven people with dementia. CONCLUSION Further work is needed to establish practice guidelines for the management of cancer in people with dementia. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
Abstract
"Basal-like" breast cancer (BLBC) is a very aggressive subtype of breast cancer. BLBC has very poor prognosis — median time to distant recurrence is just 2.6 years vs. 5 years overall, and survival time from diagnosis of distant metastatic disease is 9 months vs. 22 months. BLBC tumors usually do not express ER, Her2, or progesterone receptor. As such, they cannot be treated by the current targeted therapies, which target these molecules. What drive the formation and progression of BLBCs is largely unclear.
Ras GTPases are best known for mediating growth factor signaling. Oncogenic mutations in the RAS genes, K-RAS in particular, are found in more than 30% of human tumors. Surprisingly, oncogenic RAS mutations are rare in breast cancer. However, we found that wild-type N-RAS is overexpressed in BLBCs, possibly partly via promoter demethylation, but not in other breast cancer subtypes. Repressing N-RAS inhibits transformation and tumor growth, while overexpressing it enhances these processes even in preinvasive BLBC cells. In contrast, in breast cancer cells of other subtypes, repressing N-RAS expression does not affect growth and transforming activities. We identified N-Ras-responsive genes, most of which encode chemokines and cytokines, e.g., IL8. High expression levels of these N-Ras-responsive genes as well as of N-RAS itself in tumors correlate with poor patient outcome. N-Ras, but not K-Ras, induces IL8 by binding and activating the cytoplasmic pool of JAK2; IL8 then acts on both the cancer cells and stromal fibroblasts.
In conclusion, N-Ras drives BLBC by promoting transformation in epithelial cells, which may in turn remodel the tumor microenvironment to create a proinvasive state. Although oncogenic mutations affecting RAS are common in many other human cancers, tumorigenesis in an important subset of breast cancers is driven instead by increasing activity of wild-type N-Ras. Thus, to fully assess the impact of Ras on tumorigenesis, the role of wild-type as well as mutant Ras proteins must be carefully examined.

Abstract
Vaginal dryness is a common condition that is particularly prevalent during and after the menopause, and is one of the symptoms of vulvovaginal atrophy/genitourinary syndrome of menopause. The impact of vaginal dryness on interpersonal relationships, quality of life, daily activities, and sexual function can be significant, but is frequently underestimated. Furthermore, barriers exist to treatment-seeking, and this condition is often underreported and undertreated. Greater education about vaginal dryness and the range of available treatments is essential to encourage more women to seek help for this condition. Personal lubricants and moisturizers are effective at relieving discomfort and pain during sexual intercourse for women with mild to moderate vaginal dryness, particularly those who have a genuine contraindication to estrogen, or who choose not to use estrogen. However, there is a distinction between lubricants and moisturizers, and notable differences between commercially available products. Women should be advised to choose a product that is optimally balanced in terms of both osmolality and pH, and is physiologically most similar to natural vaginal secretions. A series of recommendations for the use of vaginal lubricants and moisturizers, either on their own or in combination with systemic or topical hormone replacement therapy, is presented.

Abstract
This brief communication reports on the main findings and recommendations from the 2014 Science Forum organized by CropLife America. The aim of the Forum was to gain a better understanding of the current status of population models and how they could be used in ecological risk assessments for threatened and endangered species potentially exposed to pesticides in the United States. The Forum panelists' recommendations are intended to assist the relevant government agencies with implementation of population modeling in future endangered species risk assessments for pesticides. The Forum included keynote presentations that provided an overview of current practices, highlighted the findings of a recent National Academy of Sciences report and its implications, reviewed the main categories of existing population models and the types of risk expressions that can be produced as model outputs, and provided examples of how population models are currently being used in different legislative contexts. The panel concluded that models developed for listed species assessments should provide quantitative risk estimates, incorporate realistic variability in environmental and demographic factors, integrate complex patterns of exposure and effects, and use baseline conditions that include present factors that have caused the species to be listed (e.g., habitat loss, invasive species) or have resulted in positive management action. Furthermore, the panel advocates for the formation of a multipartite advisory committee to provide best available knowledge and guidance related to model implementation and use, to address such needs as more systematic collection, digitization, and dissemination of data for listed species; consideration of the newest developments in good modeling practice; comprehensive review of existing population models and their applicability for listed species assessments; and development of case studies using a few well-tested models for particular species to demonstrate proof of concept. To advance our common goals, the panel recommends the following as important areas for further research and development: quantitative analysis of the causes of species listings to guide model development; systematic assessment of the relative role of toxicity versus other factors in driving pesticide risk; additional study of how interactions between density dependence and pesticides influence risk; and development of pragmatic approaches to assessing indirect effects of pesticides on listed species.

Abstract
INTRODUCTION The adoption of regional and epidural analgesia in UK military personnel injured in action during Op HERRICK increased from 2008, in line with structural and environmental developments in the UK medical treatment facility. Historically, there have been concerns that invasive analgesic techniques could carry an increased risk of infection, due to the mechanism of injury and the environmental conditions in which the injuries were sustained. Consequently, the epidural and continuous peripheral nerve blockade (CPNB) catheters that were inserted in UK military personnel during a 33-month period of Op HERRICK were clinically and microbiologically examined, after subsequent admission to the University Hospitals Birmingham (UHB) NHS Trust. METHODS Data on epidural and CPNB insertions were collected via the specialist pain service at UHB over the study period, including de novo and replacement insertions performed in both Afghanistan and the UK. Patients were regularly reviewed and relevant clinical concerns were documented in patients' case notes as necessary. The anatomical site, duration of placement and the results of microbiological culture of the epidural and CPNB catheter tips were all recorded. RESULTS Overall, 236 catheters were assessed, of which 151 catheter tips (64%) were cultured (85 epidural, 66 CPNB). Of these, 48 grew bacteria (34% of cultured epidurals and 29% of cultured CPNB). There was no difference between the colonisation rates of epidurals inserted in Afghanistan and the UK. Only one infection related to a misplaced epidural catheter was confirmed. CONCLUSIONS With the exception of the epidural (34%) and proximal sciatic (42%) catheters, these figures, in a military cohort characterised by significant injury scores, are consistent with those reported for civilian surgical patients. The results strongly support the expansion of regional analgesia during Op HERRICK from 2008 onwards. The outcomes suggest a possible translation into civilian major trauma practice.

Abstract
The lack of a common exchange format for mathematical models in pharmacometrics has been a long-standing problem. Such a format has the potential to increase productivity and analysis quality, simplify the handling of complex workflows, ensure reproducibility of research, and facilitate the reuse of existing model resources. Pharmacometrics Markup Language (PharmML), currently under development by the Drug Disease Model Resources (DDMoRe) consortium, is intended to become an exchange standard in pharmacometrics by providing means to encode models, trial designs, and modeling steps.

Abstract
At least half of patients with chronic graft-versus-host-disease (cGVHD), the leading cause of morbidity and non-relapse mortality after allogeneic stem cell transplantation, have oral manifestations: mucosal lesions, salivary dysfunction, and limited mouth-opening. cGVHD may manifest in a single organ or affect multiple organ systems, including the mouth, eyes, and the skin. The interrelationship of the 3 oral manifestations of cGVHD with each other and with the specific manifestations of extraoral cGVHD has not been studied. In this analysis, we explored, in a large group of patients with cGVHD, the potential associations between: (1) oral mucosal disease and erythematous skin disease, (2) salivary gland dysfunction and lacrimal gland dysfunction, and (3) limited mouth-opening and sclerotic skin cGVHD. Study participants, enrolled in a cGVHD Natural History Protocol (NCT00331968, n = 212), underwent an oral examination evaluating: (1) mucosal cGVHD [NIH Oral Mucosal Score (OMS)], (2) salivary dysfunction (saliva flow and xerostomia), and (3) maximum mouth-opening measurement. Parameters for dysfunction (OMS > 2, saliva flow ≤ 1 mL/5 min, mouth-opening ≤ 35 mm) were analyzed for association with skin cGVHD involvement (erythema and sclerosis, skin symptoms), lacrimal dysfunction (Schirmer's tear test, xerophthalmia), Lee cGVHD Symptom Scores, and NIH organ scores. Oral mucosal disease (31% prevalence) was associated with skin erythema (P < 0.001); salivary dysfunction (11% prevalence) was associated with lacrimal dysfunction (P = 0.010) and xerostomia with xerophthalmia (r = 0.32, P = 0.001); and limited mouth-opening (17% prevalence) was associated with skin sclerosis (P = 0.008) and skin symptoms (P = 0.001). There was no association found among these 3 oral cGVHD manifestations. This analysis supports the understanding of oral cGVHD as 3 distinct diseases: mucosal lesions, salivary gland dysfunction, and mouth sclerosis. Clear classification of oral cGVHD as 3 separate manifestations will improve clinical diagnosis, observational research data collection, and the definitions of outcome measures in clinical trials.

Abstract
PRIMARY OBJECTIVE To investigate how a vestibular deficit following an acquired brain injury (ABI) affects an individuals' quality-of-life. RESEARCH DESIGN A qualitative exploratory design. PARTICIPANTS Nine community dwelling individuals who experienced significant symptoms and limitations as a result of their vestibular deficits. METHODS The individuals participated in face-to-face interviews with open ended questions. Data was analysed initially using a case study research approach, exploring the experience for each individual and then cross-case analysis to determine common themes for the group with the assistance of nVivo 10 qualitative analysis software. RESULTS Thematic analysis determined four main themes arising from the interviews; (1) validation, (2) definitive diagnosis is more difficult amongst an array of ABI symptoms, (3) vestibular adaptation is more difficult in the presence of an ABI and (4) emotional and social. CONCLUSION Individuals who suffer a brain injury and experience vestibular symptoms as part of their overall presentation are not diagnosed in a timely manner, with individuals, their families, associates and even health professionals feeling uncertain of the legitimacy of their reported symptoms. It is important that all patients who experience an acquired brain injury are screened for vestibular impairment and, if necessary, receive vestibular rehabilitation including explanation and education.
