    Abstract Altered cellular responses to DNA damage can contribute to cancer development, progression, and therapeutic resistance. Mutations in key DNA damage response factors occur across many cancer types, and the DNA damage-responsive gene, TP53, is frequently mutated in a high percentage of cancers. We recently reported that an alternative splicing pathway induced by DNA damage regulates alternative splicing of TP53 RNA and further modulates cellular stress responses. Through damage-induced inhibition of the SMG1 kinase, TP53 pre-mRNA is alternatively spliced to generate TP53b mRNA and p53b protein is required for optimal induction of cellular senescence after ionizing radiation-induced DNA damage. Herein, we confirmed and extended these observations by demonstrating that the ATM protein kinase is required for repression of SMG1 kinase activity after ionizing radiation. We found that the RNA helicase and splicing factor, DDX5, interacts with SMG1, is required for alternative splicing of TP53 pre-mRNA to TP53b and TP53c mRNAs after DNA damage, and contributes to radiation-induced cellular senescence. Interestingly, the role of SMG1 in alternative splicing of p53 appears to be distinguishable from its role in regulating nonsense-mediated RNA decay. Thus, ATM, SMG1, and DDX5 participate in a DNA damage-induced alternative splicing pathway that regulates TP53 splicing and modulates radiation-induced cellular senescence.

    Abstract Mental contamination refers to feelings of dirtiness in response to thoughts, images, or memories. Mental contamination is frequently reported after sexual trauma and is associated with symptoms of posttraumatic stress disorder (PTSD). Differences in individuals' views about morality and purity may influence the severity of mental contamination, though this has been studied primarily outside of samples assessed for trauma and/or PTSD. The present study addressed this gap by investigating scrupulosity as a prospective predictor of daily sexual trauma-related mental contamination and PTSD symptoms. Participants included 40 adult women with a history of sexual trauma and current sexual trauma-related mental contamination who completed baseline diagnostic interviews and questionnaires followed by two assessments every day for 2 weeks. The results indicate that scrupulosity was positively correlated with PTSD symptom severity and sexual trauma-related mental contamination at baseline. Scrupulosity was also a prospective predictor of increased daily sexual trauma-related mental contamination, B = 0.19, SE = 0.07, p = .010, but not daily PTSD symptoms, B = -0.10, SE = .08, p = .198. The findings indicate that scrupulosity may be an important factor in understanding recovery from sexual assault.

    Abstract Elevated plasma concentrations of several one-carbon metabolites are associated with increased CVD risk. Both diet-induced regulation and dietary content of one-carbon metabolites can influence circulating concentrations of these markers. We cross-sectionally analysed 1928 patients with suspected stable angina pectoris (geometric mean age 61), representing elevated CVD risk, to assess associations between dietary macronutrient composition (FFQ) and plasma one-carbon metabolites and related B-vitamin status markers (GC-MS/MS, LC-MS/MS or microbiological assay). Diet-metabolite associations were modelled on the continuous scale, adjusted for age, sex, BMI, smoking, alcohol and total energy intake. Average (geometric mean (95 % prediction interval)) intake was forty-nine (38, 63) energy percent (E%) from carbohydrate, thirty-one (22, 45) E% from fat and seventeen (12, 22) E% from protein. The strongest associations were seen for higher protein intake, i.e. with higher plasma pyridoxal 5'-phosphate (PLP) (% change (95 % CI) 3·1 (2·1, 4·1)), cobalamin (2·9 (2·1, 3·7)), riboflavin (2·4 (1·1, 3·7)) and folate (2·1 (1·2, 3·1)) and lower total homocysteine (tHcy) (-1·4 (-1·9, -0·9)) and methylmalonic acid (MMA) (-1·4 (-2·0, -0·8)). Substitution analyses replacing MUFA or PUFA with SFA demonstrated higher plasma concentrations of riboflavin (5·0 (0·9, 9·3) and 3·3 (1·1, 5·6)), tHcy (2·3 (0·7, 3·8) and 1·3 (0·5, 2·2)) and MMA (2·0 (0·2, 3·9) and 1·7 (0·7, 2·7)) and lower PLP (-2·5 (-5·3, 0·3) and -2·7 (-4·2, -1·2)). In conclusion, a higher protein intake and replacing saturated with MUFA and PUFA were associated with a more favourable metabolic phenotype regarding metabolites associated with CVD risk.

    Abstract Background: Workplace violence is a regular feature of emergency departments (ED) and reported to be increasing in frequency and severity. There is a paucity of data from regional EDs in Australia. The aim of this study was to identify the perpetrator and situational characteristics associated with security alerts in regional emergency departments.
    Methods: This retrospective descriptive study was conducted in two regional Australian hospital EDs. All incident reports, hospital summary spreadsheets, and patient medical records associated with a security alert over a two-year period (2017 - 2019) were included. The situational and perpetrator characteristics associated with security alerts in the ED were recorded.
    Results: One hundred fifty-one incidents were reported in the two-year period. Incidents most frequently occurred on late shifts and in an ED cubicle. Most incidents included multiple disciplines such as ED staff and paramedics, police and psychiatric services. One hundred twenty-five incidents had sufficient information to categorise the perpetrators. Mental and behavioural disorders (MBD) were the most frequent perpetrator characteristic present in security alerts (n = 102, 81.6%) and were associated with increased severity of incidents. MBDs other than psychoactive substance use (PSU) were associated with 59.2% (n = 74) of incidents and 66.7% (n = 18) of injuries. PSU was associated with 42.4% (n = 53) of incidents. Following PSU and MBDs other than PSU, repeat perpetrators were the next most prominent perpetrator category (24.8% n = 31) and were almost always associated with an MBD (93.5% n = 29).
    Conclusions: Violence incidents in the ED are often complex, patients present with multiple issues and are managed across disciplines. Interventions need to extend from one size fits all approaches to targeting specific perpetrator groups. Since MBDs are one of the most significant perpetrator factors, interventions focussing on this characteristic are needed to address workplace violence in EDs.

    Abstract Introduction/objectives: Safe fish consumption is important for people who are or could become pregnant. A health system in Minnesota partnered with the Minnesota Department of Health to develop and disseminate messages to promote safe fish consumption for this population via the ChooseYourFish initiative. The ChooseYourFish message was delivered through 5 channels: the Healthy Pregnancy Program (HPP) with phone-based coaching, a clinic brochure, in the clinic after visit summary (AVS), direct mailing of the brochure with a letter, and in images on clinic waiting room monitors.
    Methods: We designed a pragmatic evaluation to understand the likelihood that each channel would result in awareness of the message and increase a recipient's intent to act on the information. We surveyed 1050 women aged 18 to 40 in March-May 2020. Results are reported with descriptive statistics.
    Results: The survey was completed by 524 respondents (51%). Respondents receiving the ChooseYourFish message through any channel except clinic monitors reported a higher awareness of recommendations about eating fish (42%-56%) than respondents in the no-message comparison group (21%). The after visit summary and Healthy Pregnancy Program channels had more confidence in following recommendations (50%-54%) and showed more intention to eat fish (61%-62%) compared to lower-intensity channels (24%-31% and 19%-32%, respectively).
    Conclusions: Messages delivered by an often-trusted source (eg, healthcare provider) were more likely to increase confidence and intent. Despite the trend toward online health information, physical brochures still have large reach. Repetition of exposure may be important. Because all communication channels have advantages and drawbacks, using multiple delivery channels is appropriate in communication campaigns.

    Abstract In this EACVI clinical scientific update, we will explore the current use of multi-modality imaging in the diagnosis, risk stratification, and follow-up of patients with aortic stenosis, with a particular focus on recent developments and future directions. Echocardiography is and will likely remain the key method of diagnosis and surveillance of aortic stenosis providing detailed assessments of valve haemodynamics and the cardiac remodelling response. Computed tomography (CT) is already widely used in the planning of transcutaneous aortic valve implantation. We anticipate its increased use as an anatomical adjudicator to clarify disease severity in patients with discordant echocardiographic measurements. CT calcium scoring is currently used for this purpose; however, contrast CT techniques are emerging that allow identification of both calcific and fibrotic valve thickening. Additionally, improved assessments of myocardial decompensation with echocardiography, cardiac magnetic resonance, and CT will become more commonplace in our routine assessment of aortic stenosis. Underpinning all of this will be widespread application of artificial intelligence. In combination, we believe this new era of multi-modality imaging in aortic stenosis will improve the diagnosis, follow-up, and timing of intervention in aortic stenosis as well as potentially accelerate the development of the novel pharmacological treatments required for this disease.

    Abstract Although cross-sectional research highlights similarities between symptoms of obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) among individuals exposed to sexual trauma, little is known about how these disorders relate over time. The goal of the present study was to examine whether 1) OCD symptoms prospectively predicted daily symptoms of PTSD, and 2) OCD and PTSD symptoms prospectively predicted daily experiences of sexual trauma-related mental contamination (i.e., dirtiness in the absence of a physical pollutant). Forty-one women with a sexual trauma history completed baseline measures of OCD and PTSD, as well as twice-daily assessments of PTSD symptoms and mental contamination over a two-week period. Total OCD symptoms and the unacceptable thoughts dimension significantly predicted daily PTSD symptoms after accounting for other OCD dimensions. Only total OCD symptoms significantly predicted daily mental contamination when examined together with total PTSD symptoms. No individual PTSD or OCD clusters/dimensions significantly predicted daily mental contamination when examined simultaneously. Findings from this study highlight the nuanced associations among OCD symptoms, PTSD symptoms, and experiences of mental contamination. Future research is needed to further understand the development of PTSD, OCD, and mental contamination over time to inform targets for intervention.

    Abstract Overland and shallow‐subsurface flows from agricultural catchments are believed to contribute towards flood‐risk and water‐quality degradation across the globe. Hedgerows are commonplace agricultural features that may disrupt these rapid hydrological pathways. Research into the hydrological functioning of hedgerows is very limited however, with no field‐based quantitative comparison of overland‐flows within hedgerows versus other land‐uses. This research is the first globally to observe changes in overland‐flow incidence, volume and water‐quality, alongside topsoil hydraulic and physico‐chemical properties, induced by a hedgerow and adjoining wild‐margin within a grassland landscape. Observations were conducted within two replicated paired‐plots between a hedgerow wild‐margin and a bordering pasture, within Cumbria, UK. Compared to adjacent pasture, hedge‐margins significantly reduced topsoil dry bulk‐density and increased porosity, and significantly increased the topsoil median permeability by a factor of 22–27. Overland‐flow models, based on direct observations, highlight that hedge‐margins are slower to produce overland‐flows than pastures, requiring an equal or greater amount of saturation before the onset of overland‐flow generation. Hedge‐margins resultantly produced less overland‐flow volume, likely due to increased infiltration, percolation and/or evapotranspiration. Soil saturation models, also based on direct observations, confirm pastures saturate faster than hedge‐margins, with hedge‐margins having extremely variable dynamics in relation to precipitation, whereas pastures have more moderate and consistent dynamics. Overland‐flow water‐quality from ‘wash‐off’ experiments highlight that hedge‐margins may store substantially more nitrate (70–260%), nitrate‐nitrite (640–650%), and loose sediment (540–3970%) on the ground surface compared to pastures; although further experimentation is needed to determine contaminant mobilization potential.
