Abstract
Abstract
Background
Myocardial infarction complicated by cardiogenic shock (MI-CS) has a poor prognosis, even with early revascularisation. Previously, intra-aortic balloon pump (IABP) use was thought to improve outcomes, but the SHOCK-II trial in 2012 found no survival benefit.
Purpose
This study aimed to determine the trends in IABP use in patients with MI-CS undergoing percutaneous intervention (PCI) over time and characteristics associated with use.
Methods
Between 2005–2018, patients presenting with MI-CS that underwent percutaneous coronary intervention (PCI) at a hospital participating in the Melbourne Interventional Group Registry were included. The primary outcome was the trend in IABP use over time. Secondary outcomes included mortality, 30-day MACCE (major adverse cardiovascular and cerebrovascular events) and predictors of outcome, determined via logistic regression.
Results
Of the 1,110 patients identified, IABP was used in 478 (43%). IABP was used more in patients with left main and left anterior descending culprit lesions (62% vs. 46%), lower ejection fraction (<35%; 18% vs. 11%), and pre-procedural inotrope use (81% vs. 73%), all p<0.05. IABP use was associated with higher inpatient bleeding (18% vs. 13%) and 30-day MACCE (58% vs. 51%), both p<0.05. The rate of MI-CS increased over time, but after 2012 there was a decline in IABP use (Figure 1). IABP use was a predictor of 30-day MACCE (OR 1.6, 95% CI 1.18–2.29, p=0.003). However, IABP was not associated with in-hospital, 30-day or long-term mortality (45% vs. 47%, p=0.44; 46% vs. 50%, p=0.25; 60% vs. 62%, p=0.39).
Conclusions
Consistent with the SHOCK II trial, IABP use is not associated with reduced short- or long-term mortality, but in this study was associated with increased short-term adverse events. IABP use is declining, but is still used in sicker patients with greater myocardium at risk, given limited alternatives.

Abstract
Abstract
Background
Opioid analgesia impairs the bioavailability and antiplatelet effect of oral P2Y12 inhibitors prompting investigation of mitigation strategies including identifying alternative analgesic agents.
Purpose
To assess the impact of intravenous fentanyl and lignocaine on the bioavailability and antiplatelet effect of ticagrelor in patients with unstable angina and non-ST elevation myocardial infarction, as well as their procedural analgesic efficacy and safety.
Methods
The LOCAL trial was a prospective, single centre, double-blind, randomized, controlled trial where intravenous lignocaine was the experimental analgesic agent assessed in this trial compared to intravenous fentanyl as procedural analgesia during coronary angiography and percutaneous coronary intervention. Patients with an indication for dual antiplatelet therapy and no contraindication were given 180mg of ticagrelor orally as integral tablets with 250 mL of tap water at the end of the case. Blood was sampled at time 0, 0.5, 1, 2 and 4 hours post administration of ticagrelor for pharmacokinetic and comprehensive pharmacodynamic analysis.
Results
Seventy patients undergoing coronary angiography with an indication for ticagrelor loading were included in the pharmacokinetic and pharmacodynamic analysis. Plasma ticagrelor levels at 2 h post loading dose were significantly lower in the fentanyl compared to lignocaine treatment arm (476 vs. 792 ng/mL, p=0.02, see figure 1). The area under the plasma-time curves for ticagrelor (987 vs. 2189 ng.h/mL, p=0.001) and its active metabolite (173 vs. 394 ng.h/mL, p<0.001) were both significantly lower in the fentanyl arm. Platelet reactivity assessed by the VerifyNow assay was higher at all time points after baseline in the fentanyl compared to lignocaine arm. The VASP flow cytometry assay demonstrated higher platelet reactivity at 2 hours in the fentanyl group (40% vs. 22% platelet reactivity index, p=0.001). The Multiplate Analyzer demonstrated higher platelet reactivity in the fentanyl arm at 60 minutes (43 vs. 26 area under the curve units, p=0.001) as did expression of activated platelet GpIIb/IIIa receptor (2829 vs. 1426 geometric mean fluorescence intensity (GMFI), p=0.006) and P-selectin (439 vs. 211 GMFI, p=0.001). High on-treatment platelet reactivity (HPR) was significantly higher in the fentanyl arm at 60 min using the MPA (41% vs. 9%, p=0.002) and 120 min using the VFN (30% vs. 3%, p=0.003) and VASP (37% vs. 6%, p=0.002) assays (see figure 2). Both drugs were well tolerated with a high level of patient satisfaction (fentanyl 94% vs. lignocaine 97%, p=0.56).
Conclusion(s)
Unlike fentanyl, lignocaine does not impair the bioavailability or delay the antiplatelet effect of ticagrelor. Both drugs were well tolerated and effective with a high level of patient satisfaction for procedural analgesia. Systemic pain medication during PCI should be reconsidered and if performed, lignocaine is a beneficial alternative to fentanyl.

Abstract
PURPOSE Evaluate the feasibility, acceptability and potential efficacy of a form of online therapy for clinical depression and/or anxiety in people living with advanced cancer. METHODS A single-arm open trial of a six-lesson clinician-supervised, internet-delivered cognitive behavioural therapy (iCBT) transdiagnostic intervention (iCanADAPT Advanced) was undertaken. Qualitative (semi-structured telephone interview conducted at 3-months) and quantitative data (questionnaires collected at pre-, post-, and 3-month follow-up) were analysed. RESULTS 27 participants partook (26 women, 56% breast cancer, mean age 56yo; average number of mental health diagnoses 1.8, with majority (81%) meeting criteria for generalised anxiety disorder). Feasibility - Unanticipated numbers (48%) of participants had physical health deterioration (cancer progression or death). iCBT had high adherence overall (completion rates: 37% did 6 lessons; 70% did 4 lessons) but adherence was higher for those whose cancer remained stable (completion rates: 43% did 6 lessons; 85% did 4 lessons). Acceptability - the intervention was acceptable to the majority of participants, with high treatment satisfaction. Advisory data was achieved regarding future versions. Potential efficacy - regardless of physical health status, participants who completed the iCBT showed a significant decrease over time in anxiety and depression symptoms. CONCLUSIONS Online therapies may be useful in assisting those living with advanced cancer dealing with clinical depression and anxiety disorders. The specific modality of clinician supervised iCBT has significant potential to be a suitable modality of online therapy.

Abstract
The discovery of cell-free fetal DNA (cffDNA) in maternal plasma has enabled a paradigm shift in prenatal testing, allowing for safer, earlier detection of genetic conditions of the fetus. Non-invasive prenatal testing (NIPT) for fetal aneuploidies has provided an alternative, highly efficient approach to first-trimester aneuploidy screening, and since its inception has been rapidly adopted worldwide. Due to the genome-wide nature of some NIPT protocols, the commercial sector has widened the scope of cell-free DNA (cfDNA) screening to include sex chromosome aneuploidies, rare autosomal trisomies and sub-microscopic copy-number variants. These developments may be marketed as 'expanded NIPT' or 'NIPT Plus' and bring with them a plethora of ethical and practical considerations. Concurrently, cfDNA tests for single-gene disorders, termed non-invasive prenatal diagnosis (NIPD), have been developed for an increasing array of conditions but are less widely available. Despite the fact that all these tests utilise the same biomarker, cfDNA, there is considerable variation in key parameters such as sensitivity, specificity and positive predictive value depending on what the test is for. The distinction between diagnostics and screening has become blurred, and there is a clear need for the education of physicians and patients regarding the technical capabilities and limitations of these different forms of testing. Furthermore, there is a requirement for consistent guidelines that apply across health sectors, both public and commercial, to ensure that tests are validated and robust and that careful and appropriate pre-test and post-test counselling is provided by professionals who understand the tests offered.

Abstract
Sexually antagonistic coevolution can drive the evolution of male traits that harm females, and female resistance to those traits. While males have been found to vary their harmfulness to females in response to social cues, plasticity in female resistance traits remains to be examined. Here, we ask whether female seed beetles Callosobruchus maculatus are capable of adjusting their resistance to male harm in response to the social environment. Among seed beetles, male genital spines harm females during copulation and females might resist male harm via thickening of the reproductive tract walls. We develop a novel micro computed tomography imaging technique to quantify female reproductive tract thickness in three-dimensional space, and compared the reproductive tracts of females from populations that had evolved under high and low levels of sexual conflict, and for females reared under a social environment that predicted either high or low levels of sexual conflict. We find little evidence to suggest that females can adjust the thickness of their reproductive tracts in response to the social environment. Neither did evolutionary history affect reproductive tract thickness. Nevertheless, our novel methodology was capable of quantifying fine-scale differences in the internal reproductive tracts of individual females, and will allow future investigations into the internal organs of insects and other animals.

A Synchrotron and Micro-CT Study of the Human Endolymphatic Duct System: Is Meniere's Disease Caused by an Acute Endolymph Backflow? Front Surg 2021; 8:662530.

Abstract
Background: The etiology of Meniere's disease (MD) and endolymphatic hydrops believed to underlie its symptoms remain unknown. One reason may be the exceptional complexity of the human inner ear, its vulnerability, and surrounding hard bone. The vestibular organ contains an endolymphatic duct system (EDS) bridging the different fluid reservoirs. It may be essential for monitoring hydraulic equilibrium, and a dysregulation may result in distension of the fluid spaces or endolymphatic hydrops. Material and Methods: We studied the EDS using high-resolution synchrotron phase contrast non-invasive imaging (SR-PCI), and micro-computed tomography (micro-CT). Ten fresh human temporal bones underwent SR-PCI. One bone underwent micro-CT after fixation and staining with Lugol's iodine solution (I2KI) to increase tissue resolution. Data were processed using volume-rendering software to create 3D reconstructions allowing orthogonal sectioning, cropping, and tissue segmentation. Results: Combined imaging techniques with segmentation and tissue modeling demonstrated the 3D anatomy of the human saccule, utricle, endolymphatic duct, and sac together with connecting pathways. The utricular duct (UD) and utriculo-endolymphatic valve (UEV or Bast's valve) were demonstrated three-dimensionally for the first time. The reunion duct was displayed with micro-CT. It may serve as a safety valve to maintain cochlear endolymph homeostasis under certain conditions. Discussion: The thin reunion duct seems to play a minor role in the exchange of endolymph between the cochlea and vestibule under normal conditions. The saccule wall appears highly flexible, which may explain occult hydrops occasionally preceding symptoms in MD on magnetic resonance imaging (MRI). The design of the UEV and connecting ducts suggests that there is a reciprocal exchange of fluid among the utricle, semicircular canals, and the EDS. Based on the anatomic framework and previous experimental data, we speculate that precipitous vestibular symptoms in MD arise from a sudden increase in endolymph pressure caused by an uncontrolled endolymphatic sac secretion. A rapid rise in UD pressure, mediated along the fairly wide UEV, may underlie the acute vertigo attack, refuting the rupture/K+-intoxication theory.

Abstract
Background: Reports vary on the incidence of vestibular dysfunction and dizziness in patients following cochlear implantation (CI). Disequilibrium may be caused by surgery at the cochlear base, leading to functional disturbances of the vestibular receptors and endolymphatic duct system (EDS) which are located nearby. Here, we analyzed the three-dimensional (3D) anatomy of this region, aiming to optimize surgical approaches to limit damage to the vestibular organ. Material and Methods: A total of 22 fresh-frozen human temporal bones underwent synchrotron radiation phase-contrast imaging (SR-PCI). One temporal bone underwent micro-computed tomography (micro-CT) after fixation and staining with Lugol's iodine solution (I2KI) to increase tissue contrast. We used volume-rendering software to create 3D reconstructions and tissue segmentation that allowed precise assessment of anatomical relationships and topography. Macerated human ears belonging to the Uppsala collection were also used. Drilling and insertion of CI electrodes was performed with metric analyses of different trajectories. Results and Conclusions: SR-PCI and micro-CT imaging demonstrated the complex 3D anatomy of the basal region of the human cochlea, vestibular apparatus, and EDS. Drilling of a cochleostomy may disturb vestibular organ function by injuring the endolymphatic space and disrupting fluid barriers. The saccule is at particular risk due to its proximity to the surgical area and may explain immediate and long-term post-operative vertigo. Round window insertion may be less traumatic to the inner ear, however it may affect the vestibular receptors.

Abstract
Cervical radiculopathy is a relatively common neurological disorder, often resulting from mechanical compression of the nerve root within the neural foramen. Anterior cervical discectomy and fusion (ACDF) is a common treatment for radicular symptoms that do not resolve after conservative treatment. One mechanism by which ACDF is believed to resolve symptoms is by replacing degenerated disc tissue with bone graft to increase the neural foramen area, however in vivo evidence demonstrating this is lacking. The aim of this study was to evaluate the effects of age, pathology, and fusion on bony neural foramen area. Participants included 30 young adult controls (<35 years old), 23 middle-aged controls (36 to 60 years old), and 36 cervical arthrodesis patients tested before and after ACDF surgery. Participants' cervical spines were imaged in the neutral, full flexion, and full extension positions while seated within a biplane radiography system. A validated model-based tracking technique determined three-dimensional vertebral position and orientation and automated software identified the neural foramen area in each head position. The neural foramen area decreased throughout the entire sub-axial cervical spine with age and pathology, however, no changes in neural foramen area were observed due solely to replacing degenerated disc tissue with bone graft. The neural foramen area was not associated with disc height in young adult controls, but moderate to strong associations were observed in middle-aged controls. The results provide evidence to inform the debate regarding localized versus systemic spinal degeneration and provide novel insight into the mechanism of pain relief after ACDF.

Abstract
AIMS To conduct a systematic review and meta-analysis to assess the efficacy, safety and tolerability of sodium-glucose co-transporter-2 inhibitors vs placebo as add-on therapy after metformin and dipeptidyl peptidase-4 inhibitor dual therapy in type 2 diabetes. METHODS This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO registration number: CRD42018099398). A search was conducted via PubMed, www.clinicaltrials.gov and Cochrane Central Register of Controlled Trials of relevant randomised controlled trials up until 14 August 2020 that compared sodium-glucose co-transporter-2 inhibitors vs placebo as add-on therapy after metformin and dipeptidyl peptidase-4 inhibitor therapy. A random-effects model was used. RESULTS Six randomised controlled trials (1661 participants) met the inclusion criteria. Compared with placebo, sodium-glucose co-transporter-2 inhibitor treatment, as add-on to metformin and dipeptidyl peptidase-4 inhibitor therapy, was associated with a significant reduction in HbA1c level [mean difference -8 mmol/mol, 95% CI -10, -6 (-0.7%, 95% CI -0.9, -0.6); P < 0.00001], in fasting plasma glucose level [mean difference -1.70 mmol/l, 95% CI -1.91, -1.49; P < 0.00001], in weight (mean difference -1.76 kg, 95% CI -2.04, -1.48; P < 0.00001) and in blood pressure (systolic blood pressure: mean difference -3.6 mmHg, 95% CI -4.8, -2.4; P < 0.00001; diastolic blood pressure: mean difference -1.5 mmHg; 95% CI -2.4, -0.6; P = 0.002). Genital mycotic infections (odds ratio 7.37, 95% CI 3.06, 17.76; P < 0.00001) were more common with sodium-glucose co-transporter-2 inhibitors, but there was no significant statistical difference in urinary tract infections (odds ratio 1.16, 95% CI 0.63, 2.13; P = 0.64), in hypoglycaemia (odds ratio 1.36, 95% CI 0.61, 3.04; P = 0.45), or in discontinuation rates due to adverse events (odds ratio 1.52, 95% CI 0.78, 2.97; P = 0.22) between the two groups. CONCLUSIONS In comparison with placebo, add-on therapy with a sodium-glucose co-transporter-2 inhibitor is significantly more efficacious in lowering HbA1c , fasting plasma glucose and weight in people with type 2 diabetes following inadequate glycaemic control with metformin and a dipeptidyl peptidase-4 inhibitor. The rate of discontinuation due to adverse events was similar despite higher risk of genital mycotic infections.

Abstract
AIMS Translation of evidence-based psycho-oncology interventions into routine care can significantly improve patient outcomes, yet effective implementation remains challenging due to numerous real-world barriers. A key factor that may influence implementation is organisational readiness for change. This mixed method study sought to identify factors associated with organisational readiness for implementing the Australian clinical pathway for the screening, assessment and management of anxiety and depression in adult cancer patients (ADAPT CP). METHODS We collected data from multidisciplinary staff across six Australian cancer services who were preparing to implement the ADAPT CP. Services were categorised as having 'high' versus 'mid-range' organisational readiness based on a median split on the Organizational Readiness for Implementing Change (ORIC) questionnaire (score range = 12-60). Qualitative data from the semi-structured interviews based on the Promoting Action Research in Health Services (PARiHS) framework were analysed thematically and compared for services with high- versus mid-range organisational readiness. RESULTS Three services with high- (mean ORIC range, 52.25-56.88), and three with mid-range (range, 38.75-46.39) organisational readiness scores were identified. Staff at services reporting higher readiness described a more collaborative and proactive service culture, strong communication processes and greater role flexibility. They also reported greater confidence in overcoming anticipated barriers and clearer strategies for addressing issues. CONCLUSIONS Levels of organisational readiness were related to distinct qualitative themes. Targeting these issues in services where readiness is mid-range or low prior to full-scale roll-out may improve staff levels of confidence and efficacy in implementing psycho-oncology-focused interventions.

Abstract
ALTHOUGH CURABLE, TB frequently leaves the individual with chronic physical and psycho-social impairment, but these consequences have been largely neglected. The 1st International Post-Tuberculosis Symposium (Stellenbosch, South Africa) was held to discuss priorities and gaps in addressing this issue. A barrier to progress has been the varied terminology and nomenclature, so the Delphi process was used to achieve consensus on definitions. Lack of sufficient evidence hampered definitive recommendations in most domains, including prevention and treatment of post-TB lung disease (PTLD), but the discussions clarified the research needed. A consensus was reached on a toolkit for future PTLD measurement and on PTLD patterns to be considered. The importance of extra-pulmonary consequences and progressive impairment throughout the life-course was identified, including TB recurrence and increased mortality. Patient advocates emphasised the need to address the psychological and social impacts post TB and called for clinical guidance. More generally, there is an urgent need for increased awareness and research into post-TB complications.

Abstract
The development of active, durable, and nonprecious electrocatalysts for hydrogen electrochemistry is highly desirable but challenging. In this work, we design and fabricate a novel interface catalyst of Ni and Co2N (Ni/Co2N) for hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR). The Ni/Co2N interfacial catalysts not only achieve a current density of -10.0 mA cm-2 with an overpotential of 16.2 mV for HER but also provide a HOR current density of 2.35 mA cm-2 at 0.1 V vs reversible hydrogen electrode (RHE). Furthermore, the electrode couple made of the Ni/Co2N interfacial catalysts requires only a cell voltage of 1.57 V to gain a current density of 10 mA cm-2 for overall water splitting. Hybridizations in the three elements of Ni-3d, N-2p, and Co-3d result in charge transfer in the interfacial junction of the Ni and Co2N materials. Our density functional theory calculations show that both the interfacial N and Co sites of Ni/Co2N prefer to hydrogen adsorption in the hydrogen catalytic activities. This study provides a new approach for the construction of multifunctional catalysts for hydrogen electrochemistry.

Abstract
INTRODUCTION More than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses. Many previous studies have suffered from inadequate power and poor precision, and even large studies have limited capacity to disaggregate data by specific causes of death, sub-populations or time since release to answer questions of clinical and public health relevance. OBJECTIVES To comprehensively document the incidence, timing, causes and risk factors for mortality in adults released from prison. METHODS We created the Mortality After Release from Incarceration Consortium (MARIC), a multi-disciplinary collaboration representing 29 cohorts of adults who have experienced incarceration from 11 countries. Findings across cohorts will be analysed using a two-step, individual participant data meta-analysis methodology. RESULTS The combined sample includes 1,337,993 individuals (89% male), with 75,795 deaths recorded over 9,191,393 person-years of follow-up. CONCLUSIONS The consortium represents an important advancement in the field, bringing international attention to this problem. It will provide internationally relevant evidence to guide policymakers and clinicians in reducing preventable deaths in this marginalized population.
