Abstract
BACKGROUND Cancer diagnostics and surgery have been disrupted by the response of health care services to the coronavirus disease 2019 (COVID-19) pandemic. Progression of cancers during delay will impact on patients' long-term survival. PATIENTS AND METHODS We generated per-day hazard ratios of cancer progression from observational studies and applied these to age-specific, stage-specific cancer survival for England 2013-2017. We modelled per-patient delay of 3 and 6 months and periods of disruption of 1 and 2 years. Using health care resource costing, we contextualise attributable lives saved and life-years gained (LYGs) from cancer surgery to equivalent volumes of COVID-19 hospitalisations. RESULTS Per year, 94 912 resections for major cancers result in 80 406 long-term survivors and 1 717 051 LYGs. Per-patient delay of 3/6 months would cause attributable death of 4755/10 760 of these individuals with loss of 92 214/208 275 life-years, respectively. For cancer surgery, average LYGs per patient are 18.1 under standard conditions and 17.1/15.9 with a delay of 3/6 months (an average loss of 0.97/2.19 LYGs per patient), respectively. Taking into account health care resource units (HCRUs), surgery results on average per patient in 2.25 resource-adjusted life-years gained (RALYGs) under standard conditions and 2.12/1.97 RALYGs following delay of 3/6 months. For 94 912 hospital COVID-19 admissions, there are 482 022 LYGs requiring 1 052 949 HCRUs. Hospitalisation of community-acquired COVID-19 patients yields on average per patient 5.08 LYG and 0.46 RALYGs. CONCLUSIONS Modest delays in surgery for cancer incur significant impact on survival. Delay of 3/6 months in surgery for incident cancers would mitigate 19%/43% of LYGs, respectively, by hospitalisation of an equivalent volume of admissions for community-acquired COVID-19. This rises to 26%/59%, respectively, when considering RALYGs. To avoid a downstream public health crisis of avoidable cancer deaths, cancer diagnostic and surgical pathways must be maintained at normal throughput, with rapid attention to any backlog already accrued.

Abstract
BACKGROUND Whilst underage drinking in the UK has been declining in recent years, prevalence is still higher than in most other Western European countries. Therefore, it is important to deliver effective interventions to reduce risk of harm. METHODS Semi-structured interviews with staff delivering an alcohol screening and brief intervention in the high-school setting. The analysis was informed by normalization process theory (NPT), interviews were open coded and then a framework applied based on the four components of NPT. RESULTS Five major themes emerged from the analysis. The majority of participants felt that the intervention could be useful, and that learning mentors were ideally suited to deliver it. However, there was a feeling that the intervention should have been targeted at young people who drink the most. CONCLUSIONS The intervention was generally well received in schools and seen as an effective tool for engaging young people in a discussion around alcohol. However, in the future schools need to consider the level of staffing in place to deliver the intervention. Furthermore, the intervention could focus more on the long-term risks of initiating alcohol consumption at a young age.

Abstract
We develop a method for solving mathematical models of messenger RNA (mRNA) translation based on the totally asymmetric simple exclusion process (TASEP). Our main goal is to demonstrate that the method is versatile and applicable to realistic models of translation. To this end we consider the TASEP with codon-dependent elongation rates, premature termination due to ribosome drop-off and translation reinitiation due to circularisation of the mRNA. We apply the method to the model organism Saccharomyces cerevisiae under physiological conditions and find an excellent agreement with the results of stochastic simulations. Our findings suggest that the common view on translation as being rate-limited by initiation is oversimplistic. Instead we find theoretical evidence for ribosome interference and also theoretical support for the ramp hypothesis which argues that codons at the beginning of genes have slower elongation rates in order to reduce ribosome density and jamming.

Abstract
OBJECTIVE To evaluate the association between marijuana use and a composite adverse pregnancy outcome using biological sampling. DESIGN Retrospective cohort study. SETTING Single tertiary center. POPULATION Young women (13-22 years old) with singleton, non-anomalous pregnancies delivered from September 2011 to May 2017. METHODS Exposure was defined as marijuana detected on universal urine toxicology testing or by self-report. Multivariable logistic regression modelling was used to estimate the effect of any marijuana use on the primary composite outcome. The effect of marijuana exposure was also estimated for self-reported use, toxicology-detected use, and multiple use detected by toxicology. MAIN OUTCOME MEASURE The primary composite outcome included spontaneous preterm birth, hypertensive disorders of pregnancy, stillbirth, or small for gestational age. RESULTS Of 1206 pregnant young women, 17.5% (n = 211) used marijuana. Among the women who used marijuana, 8.5% (n = 18) were identified by self-report alone, 63% (n = 133) by urine toxicology alone, and 28.4% (n = 60) by both. Urine toxicology testing results were available for 1092 (90.5%) births. The composite outcome occurred more frequently in pregnancies exposed to marijuana (46 versus 34%, P < 0.001). This remained significant after adjusting for race/ethnicity and tobacco in the multivariable model (adjusted OR 1.50, 95% CI 1.09-2.05). When marijuana exposure was defined by self-report only, the association with adverse pregnancy outcome became non-significant (adjusted OR 1.01, 95% CI 0.62-1.64). CONCLUSION In a population of young women with nearly universal biological sampling, marijuana exposure was associated with adverse pregnancy outcomes. The heterogeneity of findings in existing studies evaluating the impact of marijuana on mothers and neonates may result from the incomplete ascertainment of exposure. TWEETABLE ABSTRACT Marijuana use, as detected by universal urine testing, was associated with a composite adverse pregnancy outcome among young mothers.

Abstract
Abstract
Background
The primary aim of this study was to assess the difference in uptake levels of Healthy Start Food Vouchers, a means tested benefit to afford nutritious food, between 6 Health and Community Partnerships (HSCP) in Greater Glasgow and Clyde (GGC). Our secondary aim was to explore possible reasons for the observed variation.
Methods
Routinely collected Healthy Start data for the months of August to September 2017 were obtained from the UK Department of Health. Postcode sectors were matched up with their corresponding HSCPs in GGC. Analysis looked for associations between uptake rates and various HSCP area-based characteristics.
Results
Large variations were observed within GGC. Chi-square test showed a significant association between uptake and HSCP area (P < 0.0005). Trend analysis of uptake with area deprivation (P = 0.001) and resource allocation (P < 0.001) was also significant. Subjective analysis of trend direction suggested that uptake increased with deprivation and resource allocation of the HSCP.
Conclusions
Significant trends were found and the observed patterns suggested that the relationship between uptake rates and HSCP area is more complex than the geographical characteristics alone. Future studies need to look at the difference in management and awareness of the voucher scheme between Maternity teams in HSCPs.
Key messages
There is significant variation in the uptake of means tested benefits with some areas having a nearly forty percent of eligible individuals not receiving available support. A qualitative approach is required to determine the causes of low uptake rates of benefits and improve the effectiveness of maternity teams in different areas.

Abstract
BACKGROUND Influenza causes large outbreaks every year. Professionals outside healthcare, including social care staff and non-care giving roles, have a key role in protecting their clients and sustaining operational productivity through influenza vaccination. There has been little research on non-healthcare staff working with vulnerable people and those working in non-caregiving settings regarding influenza and influenza vaccination. AIMS To understand the practices, experiences, perceptions and motivations of local authority staff regarding influenza and influenza vaccination. METHODS Semi-structured focus groups were carried out with local authority staff in Gloucestershire. Transcripts were thematically analysed. RESULTS Participants tended to perceive influenza as a serious illness, where a person had a specific risk factor or during pandemics. They did not feel vulnerable unless they had previous experience of infection or had an underlying health condition. Motivation to vaccinate was based on previous experience of influenza, where they had a close family member at risk or when working directly with vulnerable clients. Beliefs about negative side effects of the vaccine were the strongest reason for vaccine refusal. Ease of access to vaccination through on-site clinics is key to uptake. Management are perceived as key motivators or blockers to vaccine uptake. CONCLUSIONS Workers outside healthcare settings do not feel vulnerable to influenza and have low motivation to vaccinate, unless they have previous experience of infection or an underlying health condition. Vaccination programmes must proactively address workers' beliefs and motivations to ensure their participation in flu vaccination programmes.

Abstract
Abstract
Objective
This pilot study examined the effectiveness of a social skills training (SST) program aimed to decrease verbal aggressive behavior and increase prosocial skills of conserved adults.
Method
Conserved adults (N = 10) with traumatic brain injury, schizophrenia, and schizoaffective disorder received SST for six weeks, an hour weekly, and they were assessed pre- and post-intervention. The Overt Aggression Scale-Modified for Neurorehabilitation-Extended was used to measure aggressive behaviors. Aggressive behavior to self, objects, and others was rated by facility staff that were not involved in the SST. Acquisition of social skills was rated by facility staff on the number of observed prosocial behavior (self-initiates greeting, responds to greeting, expresses gratitude). Only verbal aggression and prosocial scores were used given SST’s content. A paired samples t-test was conducted to evaluate the pre-post effectiveness and effect sizes.
Results
Aggression improved from M = 2.83 (SD = 3.39) to M = 1.00 (SD = 1.98), an improvement of 1.83, but was not statistically significant (t[8] = 2.28, p = .052; Cohen’s d = .76). 95% confidence interval ranged from -0.02 to 3.67. Prosocial behaviors improved from M = 8.67 (SD = 2.35) to M = 9.83 (SD = 2.41), an improvement of 1.17, but was not statistically significant (t[8] = -1.56, p = .158; Cohen’s d = .52). 95% confidence interval ranged from -2.90 to .56.
Conclusions
Effect sizes showed a decrease in aggression and social skills improvement of the participants. This SST is promising and should be examined with randomized controlled trial studies with larger sample sizes.

Abstract
Protein phosphorylation by eukaryotic protein kinases (ePKs) is a fundamental mechanism of cell signaling in all organisms. In model vertebrates, ~10% of ePKs are classified as pseudokinases, which have amino acid changes within the catalytic machinery of the kinase domain that distinguish them from their canonical kinase counterparts. However, pseudokinases still regulate various signaling pathways, usually doing so in the absence of their own catalytic output. To investigate the prevalence, evolutionary relationships, and biological diversity of these pseudoenzymes, we performed a comprehensive analysis of putative pseudokinase sequences in available eukaryotic, bacterial, and archaeal proteomes. We found that pseudokinases are present across all domains of life, and we classified nearly 30,000 eukaryotic, 1500 bacterial, and 20 archaeal pseudokinase sequences into 86 pseudokinase families, including ~30 families that were previously unknown. We uncovered a rich variety of pseudokinases with notable expansions not only in animals but also in plants, fungi, and bacteria, where pseudokinases have previously received cursory attention. These expansions are accompanied by domain shuffling, which suggests roles for pseudokinases in plant innate immunity, plant-fungal interactions, and bacterial signaling. Mechanistically, the ancestral kinase fold has diverged in many distinct ways through the enrichment of unique sequence motifs to generate new families of pseudokinases in which the kinase domain is repurposed for noncanonical nucleotide binding or to stabilize unique, inactive kinase conformations. We further provide a collection of annotated pseudokinase sequences in the Protein Kinase Ontology (ProKinO) as a new mineable resource for the signaling community.

Abstract
Abstract
Background: Patients with residual disease following neoadjuvant chemotherapy have an increased risk of relapse. Recently the CREATE-X trial demonstrated that adjuvant capecitabine (oral prodrug of 5'deoxy-5-fluorouridine), prolonged disease-free survival and overall survival among patients with HER2-negative breast cancer who had residual invasive disease after neoadjuvant chemotherapy containing anthracycline, taxane, or both. Therefore, we sought to evaluate the antitumor efficacy of 5-fluorouracil (5-FU) in patient-derived xenografts (PDXs) from residual tumors resistant to neoadjuvant chemotherapy.
Methods: Antitumor efficacy of 5-FU was assessed in vivo in three PDXs varying in hormone receptor status (0, 4% and 11% respectively), generated from residual tumors of primary breast cancer patients treated with neoadjuvant chemotherapy containing anthracycline, and taxanes. In addition, significance of timing of therapy was also assessed, comparing efficacy of initiating treatment upon implantation (immediate start cohort; mimicking treating residual disease with adjuvant therapy), with initiating treatment upon establishment of PDX (standard start cohort).
Results: 5-FU was efficacious in established PDX models that are triple negative (0% ER; p< 0.0001), low ER positive (4% ER, p=0.0213) and ER-positive (11% ER; p= 0.0390), decreasing growth compared to the cohort. However, there was no statistically significant difference between the immediate start cohort and standard start cohort. Western blot analysis of the treatment-naïve derived mouse tumors recognized RB as a predictive biomarker for 5-FU response.
Conclusion: 5-FU has anti-tumor activity in residual HER2-negative PDX models resistant to taxanes, and anthracyclines in the neoadjuvant setting.

Abstract
BACKGROUND Complications related to incorrect positioning of tube thoracostomy (TT) have been reported to be as high as 30%. The aim of this study was to assess the feasibility of flexible videoscope guided placement of a pre-loaded chest tube, permitting direct intrapleural visualization and placement (Video-Tube Thoracostomy [V-TT]). METHODS A prospective, single centre, phase 1 pilot study with a parallel control group was undertaken. The population studied were adult thoracic trauma patients requiring emergency TT who were haemodynamically stable. The intervention performed was VTT. Patients in the control group underwent conventional TT. The primary outcome was tube position as defined by a consultant radiologist's interpretation of chest x-ray (CXR) or CT. The trial was registered with ANZCTR.org.au (ACTRN: 12,615,000,870,550). RESULTS There were 37 patients enrolled in the study - 12 patients allocated to the VTT intervention group and 25 patients allocated to conventional TT. Mean age of participants was 48 years (SD 15) in intervention group and 46 years (SD 15) years in the control group. In the VTT group all patients were male; the indications were pneumothorax (83%), haemothorax (8%) and haemopneumothorax (8%). The median injury severity score was 23 (16-28). There were 1 positional and 1 insertional complications. In the control group 72% of patients were male, the indications were pneumothorax (56%), haemothorax (4%) and haemopneumothorax (40%). The median injury severity score was 24 (14-36). There were 8 (32%) positional complications and no insertional complications. CONCLUSION V-TT was demonstrated to be a feasible alternative to conventional thoracostomy and merits further investigation.

Abstract
Prior research with a rat model of behavioral therapy [i.e., effort-based reward (EBR) contingency training] suggests that strengthened associations between physical effort and desired outcomes enhance neurobiological indices of resilience. In the current study, male and female Long-Evans rats were exposed to either six weeks of EBR training or noncontingent training prior to 10 days of exposure to chronic unpredictable stress (CUS). Subsequently, all animals were exposed to a problem-solving task and then trained in a spatial learning/foraging task, the Dry Land Maze (DLM). Following habituation training and test trials, rats were assessed in a probe trial that generated a prediction error (cognitive uncertainty). Results indicated that, during CUS exposure, contingency-training enhanced dehydroepiandrosterone/corticosterone ratios (consistent with healthier stress responses), especially in male rats. Additionally, contingency training increased exploratory behaviors in the probe trial as well as differentially influenced on-task problem-solving performance in males and females. Following the probe trial, brains were exposed to histological analyses to determine the effects of sex and contingency training on various neurobiological markers. Contingency training decreased BDNF-immunoreactivity (ir) in the hippocampus CA1 and lateral habenula, implicating differential neuroplasticity responses in the training groups. Further, coordinated fos-ir activation in areas associated with emotional resilience (i.e., motivation-regulation) was observed in contingent-trained animals. In sum, the current findings confirm that behavioral training is associated with neurobiological markers of emotional resilience; however, further assessments are necessary to more accurately determine the therapeutic potential for the EBR contingency training model.

Abstract
Background There is concern around alcohol consumption in mid to later life yet little understanding about what influences this behaviour. No previous research has explored the extent to which adults in mid to later life may be exposed to alcohol references in the media. This project aimed to determine the frequency of alcohol references on radio stations with a high proportion of listeners in mid to later life. Methods Content analysis of alcohol references on four popular UK music-based radio stations with a high proportion of listeners aged 55-64 years over three time points. Results Alcohol references occur frequently, but vary by time of year and type of radio station. When alcohol is mentioned its consumption is portrayed as the norm, without negative consequences. On three commercial stations, the majority of mentions came from advertising, whereas on BBC Radio 2 nearly all references were talk-based. All adverts for direct promotion of alcohol were by supermarkets. Alcohol was frequently associated with celebrations, socializing or something to consume for its own sake. Conclusions Adults in the age group 55-64 may be exposed to references to alcohol that could serve to reinforce norms of consumption of alcohol and promote purchases of cheap alcohol.

Abstract
Background Diagnosis of malaria in pregnancy is problematic due to the low sensitivity of conventional diagnostic tests (rapid diagnostic test and microscopy), which is exacerbated due to low peripheral parasite densities, and lack of clinical symptoms. In this study, six potential biomarkers to support malaria diagnosis in pregnancy were evaluated. Methods Blood samples were collected from pregnant women at antenatal clinic visits and at delivery. Microscopy and real-time PCR were performed for malaria diagnosis and biomarker analyses were performed by ELISA (interleukin 10, IL-10; tumor necrosis factor-α, TNF-α; soluble tumor necrosis factor receptor II, sTNF-RII; soluble fms-like tyrosine kinase 1, sFlt-1; leptin and apolipoprotein B, Apo-B). A placental biopsy was collected at delivery to determine placental malaria. Results IL-10 and sTNF-RII were significantly higher at all time-points in malaria-infected women (p < 0.001). Both markers were also positively associated with parasite density (p < 0.001 and p = 0.003 for IL-10 and sTNF-RII respectively). IL-10 levels at delivery, but not during pregnancy, were negatively associated with birth weight. A prediction model was created using IL-10 and sTNF-RII cut-off points. For primigravidae the model had a sensitivity of 88.9% (95%CI 45.7–98.7%) and specificity of 83.3% (95% CI 57.1–94.9%) for diagnosing malaria during pregnancy. For secundi- and multigravidae the sensitivity (81.8% and 56.5% respectively) was lower, while specificity (100.0% and 94.3% respectively) was relatively high. Sub-microscopic infections were detected in 2 out of 3 secundi- and 5 out of 12 multigravidae. Conclusions The combination of biomarkers IL-10 and sTNF-RII have the potential to support malaria diagnosis in pregnancy. Additional markers may be needed to increase sensitivity and specificity, this is of particular importance in populations with sub-microscopic infections or in whom other inflammatory diseases are prevalent.
