    Objectives To date the reported outcomes of surgical aortic valve replacement (SAVR) are mainly in the settings of trials comparing it with evolving transcatheter aortic valve implantation. We set out to examine characteristics and outcomes in people who underwent SAVR reflecting a national cohort and therefore ‘real-world’ practice. Design Retrospective analysis of prospectively collected data of consecutive people who underwent SAVR with or without coronary artery bypass graft (CABG) surgery between April 2013 and March 2018 in the UK. This included elective, urgent and emergency operations. Participants’ demographics, preoperative risk factors, operative data, in-hospital mortality, postoperative complications and effect of the addition of CABG to SAVR were analysed. Setting 27 (90%) tertiary cardiac surgical centres in the UK submitted their data for analysis. Participants 31 277 people with AVR were identified. 19 670 (62.9%) had only SAVR and 11 607 (37.1%) had AVR+CABG. Results In-hospital mortality for isolated SAVR was 1.9% (95% CI 1.6% to 2.1%) and was 2.4% for AVR+CABG. Mortality by age category for SAVR only were: 75 years=2.2%. For SAVR+CABG these were; 2.2%, 1.8% and 3.1%. For different categories of EuroSCORE, mortality for SAVR in low risk people was 1.3%, in intermediate risk 1% and for high risk 3.9%. 74.3% of the operations were elective, 24% urgent and 1.7% emergency/salvage. The incidences of resternotomy for bleeding and stroke were 3.9% and 1.1%, respectively. Multivariable analyses provided no evidence that concomitant CABG influenced outcome. However, urgency of the operation, poor ventricular function, higher EuroSCORE and longer cross clamp and cardiopulmonary bypass times adversely affected outcomes. Conclusions Surgical SAVR±CABG has low mortality risk and a low level of complications in the UK in people of all ages and risk factors. These results should inform consideration of treatment options in people with aortic valve disease

    Two kinds of influence graphs are commonly used in artificial intelligence to modelize influence networks: bayesian networks [Naïm et al., 2004] and cognitive maps [Tolman, 1948]. Influence graphs provide mechanisms to highlight the influence between concepts. Cognitive maps represent a concept by a text and an influence by an arc to which a value is associated

    BACKGROUND: This study explored the oral health promotion practices of Australian community mental health professionals working with people living with severe mental illness (SMI). METHODS: An anonymous cross-sectional web-based survey was distributed to all Community Rehabilitation and Support Workers (CRSWs) working at Neami National (n = 471), an Australian community mental health service. The validated questionnaire assessed participants' self-rated oral health knowledge and confidence (7 questions); their perceived barriers (9 questions) and attitudes (5 questions) to oral health promotion; and their oral health promotion practices (7 questions). Differences in responses between groups were analysed using Chi-square, Fisher's exact and Mann-Whitney U tests. Logistic Regression Analysis served to explore the probability of providing oral health support to mental health consumers. RESULTS: A total of 141 CRSWs were included in this study, achieving a response rate of 30 percent. Roughly two-fifths (39.0%) of participants had oral health training in the previous 12-months. The majority of CRSWs (89.3%) believed ('Agreed' or 'Strongly agreed') that mental health support workers have a role to play in promoting oral health. However, less than half (44.0%) of CRSWs practiced oral health promotion activities when working with mental health consumers. When asked about barriers to promoting oral health, 'lack of consumer interest' was the most prevalent issue. CRSWs who had oral health training were over three-times (OR 3.5, 95% CI 1.25-9.83, p = 0.017) more likely to provide oral health support. Results showed the provision of oral health support was most strongly associated with self-rated knowledge and confidence (OR 4.089, 95% CI 1.629-10.263, p = 0.003) and attitudes to oral health promotion (OR 3.906, 95% CI 1.77-8.65, p = 0.001). CONCLUSION: The results of this study suggest that mental health support workers who have more positive attitudes to oral health promotion and who have higher self-rated oral health knowledge and confidence are more likely to provide oral health support in their professional role. Training for community mental health professionals is essential to build confidence and skills to promote oral health for mental health consumers

    Left ventricular free wall rupture after myocardial infarction has a high mortality. Suturing techniques of repair may be technically difficult and require cardiopulmonary bypass. We report a case of left ventricular rupture in a 47 year old man managed off pump employing a sutureless technique with Gelatine-Resorcin-Formalin glue and bovine pericardial patches

    Patterns of dental therapists' scope of practice and employment in Victoria, Australia

    In Australia, dental therapists have practiced only within the state-operated School Dental Services (SDS) for around forty years providing preventive, diagnostic, restorative, and health promotion services to children and adolescents in a collaborative and referral relationship with dentists. Changes to legislation in 2000 have seen limits to dental therapists’ employment removed, allowing private sector employment. This study examines the changes to dental therapists’ employment since 2000 using a self-completed questionnaire with a response rate of 82 percent. Approximately one-third of responding dental therapists reported that they spent some time employed outside the SDS in community health services and private orthodontic and general practices, which indicates an acceptance of this type of dental care provider in these areas. The clinical services that dental therapists are currently providing are a complex mix with significant variations according to type and geographical location of practice, but include high levels of patient assessment, diagnosis, treatment planning, and the restoration of teeth. The findings from this study indicate that when legislative restrictions on employment settings are removed, there is a demand and demonstrable role for dental therapist-delivered services in nongovernment dental practices

    IntroductionChest wall reconstruction was introduced for the management of patients with severe chest wall injuries. We undertook a retrospective cohort study to investigate whether the treatment was associated with improved survival compared with conservative treatment.MethodsA retrospective single institutional cohort study compared mortality following treatment of major chest wall trauma (Abbreviated Injury Scale ≥3) by chest wall reconstruction (CWR) to conservative management (Non-CWR) between September 2014 and December 2019. Univariable and multivariable associations between demographic and comorbid characteristics and mortality were estimated using Cox proportional hazard analysis and expressed as hazard ratios (HR) and corresponding confidence intervals (CI).ResultsOf a cohort of 947, CWR (n=157, 16.6%) had a lower prevalence of polytrauma (35.7 vs 56.3%, p<0.001) and head injury (11.5% vs 26.7%, p<0.001). CWR-treated patients experienced a greater number of fractured ribs, (8.3 vs 5.8, p<0.001), higher incidence of flail chest (84.9% vs 48.9%, p<0.001), higher admission to Critical Care (64.3% vs 44.1%, p<0.001), greater demand for ventilation (36.9% vs 25.6%, p=0.004) and a higher New Injury Severity Scale value (36.9 vs 34.6, p=0.003). Mortality of CWR patients was significantly lower (3.8% vs 8.6%, p=0.04), with adjusted HR 0.30 (95% CI 0.12, 0.72, p=0.008).ConclusionsChest wall reconstructive surgery, provided as a part of multidisciplinary treatment strategy for major thoracic trauma, reduces risk of mortality. The results validate the UK Government strategy, designed to reduce mortality, by centralising management of serious trauma in Major Trauma Centres
