Abstract
Abstract
Background
Physical inactivity is associated with an increased risk of cardiovascular disease. High intensity interval training (HIIT) has been shown to improve important health parameters, including aerobic capacity, arterial blood pressure, cardiac autonomic modulation and left ventricular mechanics. However, adaptations in left atrial (LA) mechanics and aortic stiffness remain unclear. Therefore, the aim of the present study was to assess any left atrial and aortic adaptations to HIIT.
Methods
Forty-one physically inactive males and females (aged 23 ± 2.7 years) volunteered for the study. Participants were randomised to either a 4-week HIIT intervention (n = 21) or 4-week control period (n = 20). The HIIT protocol consisted of 3 x 30-second maximal cycle ergometer sprints with a resistance of 7.5% body weight, interspersed with 2-minutes of active unloaded recovery. Speckle tracking imaging of the left atrium and M-Mode tracing of the aorta was performed pre and post HIIT and control period using commercially available software (EchoPac; GE Medical Systems). Analysis of covariance, with baseline measures as the covariate, was used to explore any differences in left atrial mechanics and aortic stiffness between the intervention and control groups. Stepwise linear regression analysis using LA stiffness as the dependent variable was conducted.
Results
Following 4-weeks of HIIT, there was significant improvement in LA mechanics, including LA reservoir (13.9 ± 13.4%, p = 0.033) and LA stiffness (-0.05 ± 0.04%-1, p = 0.032) compared to the control condition. In addition, improvements were observed in aortic distensibility (2.1 ± 2.7 cm2 × dyn×-1 × 103, p = 0.031) and aortic stiffness index (-2.6 ± 4.6, p = 0.041) compared to the control condition. In stepwise linear regression analysis, aortic distensibility change was significantly associated with LA stiffness change (p = 0.002), with an R2 of 0.613.
Conclusion
A short-term programme of HIIT was associated with a significant improvement in LA mechanics and aortic stiffness. These adaptations may have important health implications and contribute to the improved left ventricular diastolic and systolic mechanics, aerobic capacity and reduced arterial blood pressure previously documented following HIIT.

Abstract
Background Emergency and essential surgical, obstetric and anaesthesia (SOA) care are now recognized components of universal health coverage, necessary for a functional health system. To improve surgical care at a national level, strategic planning addressing the six domains of a surgical system is needed. This paper details a process for development of a national surgical, obstetric and anaesthesia plan (NSOAP) based on the experiences of frontline providers, Ministry of Health officials, WHO leaders, and consultants. Methods Development of a NSOAP involves eight key steps: Ministry support and ownership; situation analysis and baseline assessments; stakeholder engagement and priority setting; drafting and validation; monitoring and evaluation; costing; governance; and implementation. Drafting a NSOAP involves defining the current gaps in care, synthesizing and prioritizing solutions, and providing an implementation and monitoring plan with a projected cost for the six domains of a surgical system: infrastructure, service delivery, workforce, information management, finance and governance. Results To date, four countries have completed NSOAPs and 23 more have committed to development. Lessons learned from these previous NSOAP processes are described in detail. Conclusion There is global movement to address the burden of surgical disease, improving quality and access to SOA care. The development of a strategic plan to address gaps across the SOA system systematically is a critical first step to ensuring countrywide scale‐up of surgical system‐strengthening activities.

Abstract
INTRODUCTION Consultant posts were developed to strengthen strategic leadership whilst maintaining front line service responsibilities and clinical expertise. The nursing profession has attempted to develop tools to enable individuals to evaluate their own practice and consider relevant measurable outcomes. This study evaluated the feasibility of transferring such a nursing 'toolkit' to another health profession. METHOD This evaluation was structured around a one-day workshop where a nurse consultant impact toolkit was appraised and tested within the context of consultant radiographic practice. The adapted toolkit was subsequently validated using a larger sample at a national meeting of consultant radiographers. RESULTS There was broad agreement that the tools could be adopted for use by radiographers although several themes emerged in relation to perceived gaps within the nursing template, confirming the initial exercise. This resulted in amendments to the original scope and a proposed new evaluation tool. CONCLUSION The impact toolkit could help assess individual and collaborat ive role impact at a local and national level. The framework provides consultant radiographers with an opportunity to understand and highlight the contribution their roles have on patients, staff, their organisation and the wider profession.

Abstract
Abstract
Introduction
Delayed breast reconstructions are preferred if post mastectomy radiotherapy is indicated due to lower complication rates compared to immediate permanent implant or autologous reconstructions (AR) but cosmetic outcomes are inferior. Radiotherapy has a deleterious effect on implants and autologous tissue and often an interim tissue expander is place which has inherent pain and complications.
However, neoadjuvant radiotherapy (NART) prior to surgery allows for definitive oncological surgery to be performed with an immediate AR in a single operation and the avoidance of a temporary expander. The aim of this study is to assess the safety and downstaging impact of NART.
Methods
This is a prospective review of patients who underwent NART at GenesisCare Victoria, the Austin and the Alfred hospital. 59 LABC patients (median age 49.2 years) were divided into two groups; clinically staged and pathologically staged for reporting. There were 15 pathologically staged patients (pStage 2A-3C) and 43 clinically staged patients (cStage 2A-3B). All patients initially underwent NACT, followed by NART (median dose 50.4Gy in 28 fractions) to the breast, supraclavicular fossa and level 3 axilla with or without coverage of their Level 1 and 2 axilla, and/or internal mammary nodes. Approximately 6 weeks after completing NART, patients underwent definitive surgery and AR.
Results
All patients completed their NART with minimal toxicity and no break in treatment. 55 patients had a skin-sparing mastectomy (SSM) and 3 patients had a modified radical mastectomy. All clinically staged patients underwent an AD. ARs with a DIEP flap were performed in the majority of patients (51). The average length of hospitalisation was 6.2 days.
The Miller Payne (MP) scoring index was used to record pathological responses in clinically staged patients. Overall 36 patients achieved significant downstaging of their disease, with MP scores of 5/5 for 20 and 4/5 for 16. Only 1 patient failed to achieve any downstaging with a MP score of 1/5. All 12 Her2 positive patients, 3/5 Triple negative patients and 5/26 Luminal A/B patients achieved a MP score of 5/5. All patients achieved R0 resection margins. This included 6 patients who had initial cT4 disease (cT4a X2, cT4b X1 and cT4d X3). 15 patients had initial cN2/3 disease and all successfully underwent their axillary dissections with R0 resections achieved. 10/15 had no involved axillary nodes with significant scarring seen in 6. 5/15 had residual involved nodes with significant scarring seen in 3 patients.
Post surgical toxicities were graded using Clavien-Dindo classification. 8 significant grade 3 toxicities were seen in 6 patients, with no grade 4 or 5 toxicities. No patients developed DVT or PE. No flap losses were seen.
Median follow up is 23 months. Cosmesis was rated as good to excellent in all cases. 1 patient developed simultaneous loco-regional and distant recurrence with another 3 patients developing distant metastases only.
Conclusion
This review demonstrated that NART is a safe technique, which has not lead to an increase in surgical complication rates or resulted in a detriment in cosmetic outcome. NART can achieve a shorter, simpler reconstructive journey for patients.

Abstract
The aim of this study was to develop and evaluate mathematical models that predict mineral excretion, particularly calcium (Ca), magnesium (Mg) and selenium (Se), from lactating dairy cows. Mineral excretion can be affected by several dietary factors. A deficiency in Ca or Mg application to pasture, among other factors, can contribute to grass tetany or wheat pasture poisoning in cows, whereas an excess can cause runoff into water supplies. Manure application with high Se concentration can also result in runoff, causing the bioaccumulation of selenium in aquatic ecosystems, wetland habitats and estuaries, leading to toxic levels in fish. A database composed of studies relating to mineral utilisation in lactating dairy cows conducted after and including the year 2000 was compiled. A meta-analysis was conducted with the aim of creating multiple empirical equations to predict Ca, Mg and Se excretion from lactating dairy cows. Calcium intake, feed Ca content, milk yield, milk protein content and acid detergent fibre content in diet were positively and linearly related to Ca excretion. Dietary crude protein content and milk fat content were negatively related to Ca excretion. Magnesium intake, feed Mg content and milk yield were positively and linearly related to Mg excretion. Selenium content of diet and dry matter intake were linearly and positively related to Se excretion. Two sets of models were developed using or excluding the intake variable and both sets of models were evaluated with independent data originating from commercial herd or individual animals. In general, intake measurements improved prediction when evaluated with independent datasets (root mean square prediction error = 8% to 19% vs 14% to 26% of the average observed value). There were substantial mean biases, particularly those evaluated with data from a commercial farm, perhaps due to inaccurate feed intake measurements. Although there was generally good agreement between predicted and observed mineral excretion, model development and evaluation would benefit from an expanded database.
