RESUMO
OBJECTIVE: To better guide decisions regarding antithrombotic treatment in individual patients surviving 6 months following an acute coronary syndrome (ACS) by balancing between subsequent recurrent ischaemic and bleeding risk. METHODS: Patients surviving 6 months following an ACS were followed in an Australian registry. Ischaemic (composite of cardiovascular death, myocardial infarction or stroke) and bleeding (≥BARC 2) events were collected. A dual binary outcome modelling strategy was used arriving at a common set of variables from which bleeding and ischaemic risk could be independently determined in individual patients. Patients in whom bleeding rates exceeded composite ischaemic event rates during the follow-up period were identified. RESULTS: The cohort comprised 5,905 patients in whom 215 experienced an ischaemic event and 49 a bleeding event. The single set of variables included in both ischaemic and bleeding models (C-statistics 0.71 and 0.72 respectively) included modified TIGRIS1 ischaemic score, mode of revascularisation, history of heart failure, anaemia, multivessel disease, readmission within 6 months of index ACS and age >75. In the majority, ischaemic events were more frequent than bleeding events. In higher risk patients post coronary artery bypass grafting (CABG), bleeding events were more frequent than recurrent ischaemic events. CONCLUSION: The risk of recurrent ischaemic events exceeds bleeding in most patients followed 6 to 24 months following an ACS. Post CABG patients with comorbidities have a higher risk of bleeding over this period during which time attention should be directed towards modifiable bleeding risk factors including requirement for dual antiplatelet therapy.

OBJECTIVE: To examine the vestibulo-ocular reflex (VOR) and compensatory-saccades before and after complete unilateral vestibular deafferentation (UVD). METHODS: Forty patients were studied before and after surgery for vestibular or facial schwannoma using the video head-impulse test (vHIT) and multivariable regression. RESULTS: Prior to UVD (median(IQR), 14(58.4) days), the average VOR-gain towards the lesioned-ear was lower than in normal for all semicircular canals (lateral, anterior, posterior: 0.69, 0.72, 0.49). One-week after UVD (5(3.0) days) VOR gains were further reduced (0.22, 0.37, 0.27), however, within one-year after UVD (171(125.0) days) the lesioned-ear VOR gains had slightly increased (+0.08, +0.11, +0.03), maximally for the anterior-canal. After UVD, the VOR gain asymmetry (gain towards minus away from intact-ear) was lower for the intact posterior-canal plane (0.56, 0.56, 0.22). For the lesioned canals, the frequency and amplitude of the first compensatory-saccade increased from 61-93% and 1.9-3.6° pre-surgery, to 98-99% and to 3.1-5.9° one-week post-surgery and remained unchanged over one-year; second saccade frequency and amplitude decreased over the same timespan. CONCLUSIONS: After UVD the high-acceleration VOR for the intact posterior-canal plane is more symmetrical than the other canals. First compensatory-saccades adapt within one week and subsequently change only marginally. SIGNIFICANCE: Saccade compensation from surgical UVD is near complete by one-week.

BACKGROUND: The Royal College of Pathologists of Australasia Quality Assurance Programs runs a Quality Assurance Program for the assessment of synovial fluid crystals. It provides aliquots of synovial fluid to various laboratories. The quality of specimens can deteriorate prior to being examined. We aimed to assess whether the addition of dimethyl sulfoxide (DMSO) to synovial fluid specimens helps maintain cellular morphology. METHODS: Synovial fluid specimens were obtained from 15 patients. Each specimen was aliquoted into 24 samples, with half having DMSO added at a concentration of 10%. For each specimen, six samples containing DMSO and six samples not containing DMSO were stored at-80°C and room temperature. Samples from each group were examined at 1, 2, 3, 6, 7 and 8 weeks. Comparative Analysis: For each specimen, the final remaining aliquoted samples containing DMSO and not containing DMSO, which were stored at-80°C, were directly compared. Quantitative Analysis: A system for grading cellular morphology and assessing for artefacts and cellular clumping was applied by two independent assessors. RESULTS: Comparative Analysis: A significant difference was found between samples containing DMSO and not containing DMSO which were stored at -80°C (p = .000), in favour of those containing DMSO. Quantitative Analysis: Regarding the combined findings of Assessors 1 and 2 and the grading of cellular morphology, a significant difference was found according to "groups" (p = .000), in favour of those containing DMSO and stored at-80°C. CONCLUSIONS: DMSO contributes to the maintenance of cellular morphology in synovial fluid when stored in frozen conditions.

INTRODUCTION: MRI is generally considered the modality of choice for the assessment of rotator cuff pathology including tendinosis. Assessment of severity is currently subjective primarily based on tendon morphology and signal intensity. Limited data are available evaluating the inter-observer agreement regarding the assessment of tendinosis severity. METHODS: One hundred and twenty-four patients were prospectively enrolled in the study. Patients included were referred to two private radiology practices for shoulder MRI for any reason. Two musculoskeletal radiologists assessed the severity of tendinosis independently. Supraspinatus tendon signal was evaluated with a ROI and compared to the adjacent deltoid muscle signal, generating a ratio of tendon: muscle signal, termed the 'objective TM ratio'. The relationship between the subjective assessment of tendinosis severity and objective ratio was examined. Inter-observer agreement was also calculated. RESULTS: Tendinosis severity was graded as normal in 36 and 11 patients by readers 1 and 2, respectively, mild in 45 and 48 patients, moderate in 26 and 48 patients and severe in 10 and 10 patients. Inter-observer agreement is classified as fair (0.31 kappa co-efficient). Mean objective TM ratio increased on both the PD and TS F2 sequences as the subjective grade of tendinosis severity increased. CONCLUSION: A novel means of evaluating rotator cuff tendinosis severity is presented, demonstrated to correlate with the subjective grade of tendinosis severity. Further research is required to assess the utility of such objective measurements across varying imaging protocols whilst understanding the inherent limitations with quantifying signal intensity on MRI.

INTRODUCTION: Patients with vestibular disorders sometimes report cognitive difficulties, but there is no consensus about the type or degree of cognitive complaint. We therefore investigated subjective cognitive dysfunction in a well-defined sample of neuro-otology patients and used demographic factors and scores from a measure of depression, anxiety, and stress to control for potential confounding factors. METHODS: We asked 126 neuro-otology clinic outpatients whether they experienced difficulties with thinking, memory, or concentration as a result of dizziness or vertigo. They and 42 nonvertiginous control subjects also completed the Neuropsychological Vertigo Inventory (NVI, which measures cognitive, emotional, vision, and motor complaints), the Everyday Memory Questionnaire (EMQ), and Depression, Anxiety, and Stress Scales (DASS). RESULTS: In the initial interview questions, 60% of patients reported experiencing cognitive difficulties. Cognitive questionnaire scores were positively correlated with the overall DASS score and to a lesser extent with age and gender. Therefore, we compared patients and controls on the NVI and EMQ, using these mood and demographic variables as covariates. Linear regression analyses revealed that patients scored significantly worse on the total NVI, NVI cognitive composite, and 3 individual NVI cognition subscales (Attention, Space Perception, and Time Perception), but not the EMQ. Patients also scored significantly worse on the NVI Emotion and Motor subscales. CONCLUSIONS: Patients with dizziness and vertigo reported high levels of cognitive dysfunction, affecting attention, perceptions of space and time. Although perceptions of cognitive dysfunction were correlated with emotional distress, they were significantly elevated in patients over and above the impact of depression, anxiety, or stress.

BACKGROUND: Young-onset type 2 diabetes is an aggressive disease characterized by development of diabetic complications, including nephropathy, early in the disease course. However, within the cohort of young-onset type 1 and type 2 diabetes there are limited comparative data regarding progression to ESKD requiring renal replacement therapy or renal-related death (RRT/RRD). METHODS: Probabilistic linkage of data from the RPAH Diabetes Centre, National Death Index and Australian and New Zealand Dialysis and Transplant Registry was undertaken. Cumulative Incidence Competing Risk and Cox Proportional Hazards Modelling approaches were utilized to examine progression to ESKD in young-onset type 1 and type 2 diabetes (age of diagnosis 15-35 years). FINDINGS: Unadjusted incidence rates (95% CI) of RRT/RRD in young-onset type 1 and type 2 diabetes were 3.1 (2.3-4.0) and 4.6 (3.7-5.7) per 1000 person years respectively. After adjustment for gender, ethnicity and duration of diabetes, the HR (95% CI) of RRT/RRD in young-onset type 2 diabetes was 2.0 (1.4-2.9). The HR remained higher after further adjustment for first available cholesterol, HbA1c and systolic blood pressure but not BMI. For those who progressed to RRT, prognosis was similar irrespective of diabetes type; cumulative incidence of mortality was 40% in both young-onset type 1 and type 2 diabetes after 6 years of dialysis. INTERPRETATION: Progression to RRT/RRD is greater in young-onset type 2 diabetes than in young-onset type 1 diabetes. The increased progression is associated with increased BMI. However, once ESKD is reached, individuals with young-onset type 1 and type 2 diabetes do equally poorly.

BACKGROUND: Clinic attendance, metabolic control, engagement in self-management, and psychological health are suboptimal in young-onset (age of onset <40 years) type 2 diabetes. OBJECTIVE: We examined the effectiveness of an enhanced SMS text message-based support and reminder program in improving clinic attendance, metabolic control, engagement in self-management, and psychological health in young-onset type 2 diabetes. METHODS: A 12-month, parallel-arm, randomized controlled trial comparing an enhanced, semipersonalized SMS text message-based intervention (incorporating 1-8 supportive and/or informative text messages per month) against standard care was conducted in a specialized clinic for young adult type 2 diabetes. The primary outcome was maintenance of 100% attendance at scheduled quarterly clinical appointments. Secondary outcomes included (1) metabolic indices, (2) pathology and self-monitored blood glucose (SMBG) data availability, and (3) psychosocial well-being. RESULTS: A total of 40 participants were randomized, and 32 completed their 12-month study visit. The average participant age was 32.7 (SD 5.1) years, 50% (20/40) were male, and baseline glycated hemoglobin A1c (HbA1c) was 7.3% (SD 1.9%) (56 mmol/mol, SD 20). A higher proportion of the intervention group achieved 100% attendance (12/21, 57%, vs 5/19, 26%, for the control group); Kaplan-Meier analysis demonstrated significantly greater cumulative attendance in the intervention group (P=.04). There were no between-group differences in HbA1c, BMI, lipids, or availability of pathology and SMBG data. Odds of recording an improvement in the Diabetes Empowerment Scale-Short Form score were higher in the intervention group at 6 months (odds ratio [OR] 4.3, 95% CI 1.1-17), with attenuation of this effect at study end (OR 3.1, 95% CI 0.9-11). Program acceptability was high; >90% of participants would recommend the program to new patients. CONCLUSIONS: An enhanced SMS text message-based support and reminder program doubled scheduled clinic attendance rates for patients with young-onset type 2 diabetes. The program was highly acceptable and provided early support for patient empowerment but had no significant effect on measures of metabolic control or self-management.

BACKGROUND: There has been increasing focus to improve the quality of recovery following anterior cervical spine surgery (ACSS). Postoperative pain and nausea are the most common reasons for prolonged hospital stay and readmission after ACSS. Superficial cervical plexus block (SCPB) provides site-specific analgesia with minimal side effects, thereby improving the quality of recovery. The aim of our study was to investigate the effect bilateral cervical plexus block has on postoperative recovery in patients undergoing ACSS. METHODS: The study is a pragmatic, multi-centre, blinded, parallel-group, randomised placebo-controlled trial. 136 eligible patients (68 in each group) undergoing ACSS will be included. Patients randomised to the intervention group will have a SCPB administered under ultrasound guidance with a local anaesthetic solution (0.2% ropivacaine, 15mL); patients randomised to the placebo group will be injected in an identical manner with a saline solution. The primary outcome is the 40-item quality of recovery questionnaire score at 24 h after surgery. In addition, comparisons between groups will be made for a 24-h opioid usage and length of hospital stay. Neck pain intensity will be quantified using the numeric rating scale at 1, 3, 6 and at 24 h postoperatively. Incidence of nausea, vomiting, dysphagia or hoarseness in the first 24 h after surgery will also be measured. DISCUSSION: By conducting a blinded placebo trial, we aim to control for the bias inherently associated with a tangible medical intervention and show the true treatment effect of SCPB in ACSS. A statistically significant result will indicate an overall improved quality of recovery for patients; alternatively, if no benefit is shown, this trial will provide evidence that this intervention is unnecessary. TRIAL REGISTRATION: ClinicalTrials.gov ACTRN12619000028101. Prospectively registered on 11 January 2019 with Australia New Zealand Clinical Trials Registry.

BACKGROUND: We characterise the history, vestibular tests, ictal and interictal nystagmus in vestibular migraine. METHOD: We present our observations on 101 adult-patients presenting to an outpatient facility with recurrent spontaneous and/or positional vertigo whose final diagnosis was vestibular migraine (n = 27) or probable vestibular migraine (n = 74). Ictal and interictal video-oculography, caloric and video head impulse tests, vestibular-evoked myogenic potentials and audiometry were performed. RESULTS: Common presenting symptoms were headache (81.2%), spinning vertigo (72.3%), Mal de Débarquement (58.4%), and motion sensitivity (30.7%). With fixation denied, ictal and interictal spontaneous nystagmus was observed in 71.3 and 14.9%, and purely positional nystagmus in 25.8 and 55.4%. Spontaneous ictal nystagmus was horizontal in 49.5%, and vertical in 21.8%. Ictal spontaneous and positional nystagmus velocities were 5.3 ± 9.0°/s (range 0.0-57.4), and 10.4 ± 5.8°/s (0.0-99.9). Interictal spontaneous and positional nystagmus velocities were <3°/s in 91.8 and 23.3%. Nystagmus velocities were significantly higher when ictal (p < 0.001/confidence interval: 2.908â6.733, p < 0.001/confidence interval: 5.308â10.085). Normal lateral video head impulse test gains were found in 97.8% (mean gain 0.95 ± 0.12) and symmetric caloric results in 84.2% (mean canal paresis 7.0 ± 23.3%). Air- and bone-conducted cervical-vestibular-evoked myogenic potential amplitudes were symmetric in 88.4 and 93.4% (mean corrected amplitude 1.6 ± 0.7, 1.6 ± 0.8) with mean asymmetry ratios of 13.0 and 9.0%. Air- and bone-conducted ocular-vestibular-evoked myogenic potentials were symmetric in 67.7 and 97.2% (mean amplitude 9.2 ± 6.4 and 20.3 ± 12.8 µV) with mean asymmetry ratios of 15.7 and 9.9%. Audiometry was age consistent and symmetric in 85.5%. CONCLUSION: Vestibular migraine is characterised by low velocity ictal spontaneous nystagmus, which can be horizontal, vertical, or torsional, and normal audiovestibular test results.

OBJECTIVE: To determine whether the availability of invasive coronary angiography at the hospital of presentation influences catheterisation rates for patients with acute coronary syndrome (ACS), and whether presenting to a catheterisation-capable hospital is associated with better outcomes for patients with ACS. DESIGN, SETTING: Retrospective cohort study; analysis of Cooperative National Registry of Acute Coronary Events (CONCORDANCE) data. SETTING, PARTICIPANTS: Adults admitted with ACS to 43 Australian hospitals (including 31 catheterisation-capable hospitals), February 2009 - October 2018. MAIN OUTCOME MEASURES: Major adverse cardiovascular events (myocardial infarction, stroke, congestive heart failure, cardiogenic shock, cardiovascular death) and all-cause deaths in hospital and by six and 12- or 24-month follow-up. RESULTS: The proportion of women among the 5637 patients who presented to catheterisation-capable hospitals was smaller than for the 2608 patients who presented to hospitals without catheterisation facilities (28% v 33%); the proportion of patients diagnosed with ST elevation myocardial infarction was larger (32% v 20%). The proportions of patients who underwent catheterisation (81% v 70%) or percutaneous coronary intervention (49% v 35%) were larger for those who presented to catheterisation-capable hospitals. The baseline characteristics of patients who underwent catheterisation were similar for both presentation hospital categories, as were rates of major adverse cardiovascular events and all-cause death in hospital and by 6- and 12- or 24-month follow-up. CONCLUSIONS: Although a larger proportion of patients who presented to catheterisation-capable hospitals underwent catheterisation, patients with similar characteristics were selected for the procedure, independent of the hospital of presentation. Major outcomes for patients were also similar, suggesting equitable management of patients with ACS across Australia.

BACKGROUND: Many patients with atrial fibrillation (AF) do not receive oral anticoagulant (OAC) therapy. The aims of this study were to 1) document receipt of OAC among patients with a history of AF admitted with an acute coronary syndrome (ACS); and to 2) determine whether hospital admission was associated with an improvement in prescription of OAC therapy. METHODS: Using Australian data from the Cooperative National Registry of Acute Coronary Care, Guideline Adherence and Clinical Events (CONCORDANCE) and Global Registry of Acute Coronary Events (GRACE) registries, 1,479 patients with a history of AF presenting with an ACS were separated into two groups: aspirin monotherapy/no therapy (No OAC) or oral anticoagulant ± aspirin (OAC). Clinical characteristics and in-hospital treatments and outcomes were compared. RESULTS: Of 1,479 patients, 532 (36%) with a history of AF presented on OAC with the remainder receiving antiplatelet (n=580 [39%]) or no antithrombotic therapy (n=367 [25%]). Treatment with OAC prior to presentation increased during the 18 years of the study (27% to 56%, p=0.0002). Ninety-five per cent (95%) of the OAC group had a CHA2DS2-VA score >1 vs 88% of the No OAC group (p<0.001). Patients receiving OAC had a lower prevalence of bleeding risk factors than no OAC patients (p<0.001). Only 39% of this cohort was discharged on an OAC, although this increased during the observational period (26-61%, p≤0.0001). CONCLUSION: In patients presenting with an ACS with a history of AF, receipt of OAC has improved over time but remains suboptimal. There is minimal escalation in provision of OAC therapy during hospital care, indicating missed opportunities to address this evidence practice gap.

BACKGROUND: Interventions involving both exercise and dietary modification are effective in reducing steatosis in nonalcoholic fatty liver disease (NAFLD). However, exercise alone may reduce liver fat and is known to have other positive effects on health. The primary aim of this study was to systematically review the effect of exercise alone without dietary intervention on NAFLD and to examine correlations across changes in liver fat and metabolic markers during exercise. METHODS: Relevant online databases were searched from earliest records to May 2020 by two researchers. Studies were included where the trial was a randomized controlled trial, participants were adults, exercise intervention was longer than 4 weeks, no dietary intervention occurred, and the effect of the intervention on liver fat was quantified via magnetic resonance imaging/proton magnetic resonance spectroscopy. RESULTS: Of 21 597 studies retrieved, 16 were included involving 706 participants. Exercise was found to have a beneficial effect on liver fat without dietary modification (-2.4%, -3.13 to -1.66) (mean, 95% CI). Pearson correlation showed significant relationships between change in liver fat and change in weight (r = 0.67, P = .007), liver enzymes aspartate aminotransferase (r = 0.76, P = .002) and alanine aminotransferase (r = 0.91, P < .001), and cardiorespiratory fitness VO2 peak (peak volume oxygen consumption) (r = -0.88, P = .004). By multivariate regression, change in weight and change in VO2 peak significantly contributed to change in liver fat (R2 = 0.84, P = .01). CONCLUSIONS: This systematic review found that exercise without dietary intervention improves liver fat and that clinical markers may be useful proxies for quantifying liver fat changes.

We assessed the association of BMI with all-cause and cardiovascular (CV) mortality in a contemporary acute coronary syndrome cohort. Patients from the Australian Cooperative National Registry of Acute Coronary Care, Guideline Adherence and Clinical Events and Global Registry of Acute Coronary Events between 2009 and 2019, were divided into BMI subgroups (underweight: <18.5, healthy: 18.5 to 24.9, overweight: 25 to 29.9, obese: 30 to 39.9, extremely obese: >40). Logistic regression was used to determine the association between BMI group and outcomes of all cause and CV death in hospital, and at 6 months. 8,503 patients were identified, mean age 64 ± 13, 72% male. The BMI breakdown was: underweight- 95, healthy- 2,140, overweight- 3,258, obese- 2,653, extremely obese- 357. Obese patients were younger (66 ± 12 vs 67 ± 13), with more hypertension, diabetes, and dyslipidemia vs healthy (all p < 0.05). Obese had lower hospital mortality than healthy: all-cause: 1% versus 4%, aOR (95% CI): 0.49(0.27, 0.87); CV: 1% versus 3%, 0.51(0.27, 0.96). At 6-month underweight had higher mortality than healthy: all-cause: 11% versus 4%, 2.69(1.26, 5.76); CV: 7% versus 1%, 3.54(1.19, 10.54); whereas obese had lower mortality: all-cause: 1% versus 4%, 0.48(0.29, 0.77); CV: 0.4% versus 1%, 0.42(0.19, 0.93). When BMI was plotted as a continuous variable against outcome a U-shaped relationship was demonstrated, with highest event rates in the most obese (>60). In conclusion, BMI is associated with mortality following an acute coronary syndrome. Obese patients had the best outcomes, suggesting persistence of the obesity paradox. However, there was a threshold effect, and favorable outcomes did not extend to the most obese.

PURPOSE: To report early safety and efficacy of Descemet stripping only (DSO) supplemented with ripasudil. METHODS: A pre-post clinical trial with a historical control group for time to heal and cell count parameters. The study received ethics approval and was conducted with oversight of a data safety monitoring board. All enrolled patients had a superior endothelial cell count of >1000 cells/mm2 and were symptomatic from the presence of central guttata degrading vision and/or producing glare. DSO was carried out with a peeling technique and not combined with any other intervention. Ripasudil 0.4% was applied topically from day 1 postoperatively at a dose of 6 times/d until corneal clearance. Cases with relapse of edema were permitted to restart on ripasudil at a reduced dose of 2 drops/d for a further 2 weeks. Stopping rules with progression to a corneal graft were established. Baseline ocular and systemic investigations were carried out and repeated at varying intervals to monitor for local and systemic adverse events. RESULTS: Twenty-three eyes of 23 patients met the inclusion criteria and underwent DSO. Twenty-two of 23 eyes achieved corneal clearance at a mean time of 4.1 weeks. In all patients achieving clearance, improvement in vision was recorded. Improvement in mean uncorrected visual acuity was 0.20 Logarithm of the minimum angle of resolution (LogMar), and improvement in mean best spectacle corrected visual acuity was 0.156 LogMar. One patient failed to clear and underwent Descemet membrane endothelial keratoplasty at week 12. Twenty-one of 22 patients achieving corneal clearance expressed satisfaction with the procedure. The commonest systemic side effect of topical ripasudil was gastrointestinal upset (24%), and the commonest local side effect was ocular irritation (43%). No patient experienced a serious adverse event in the course of the trial. Thirty-nine percent of patients experienced a relapse of edema on ceasing ripasudil, with clearance again on recommencing. CONCLUSIONS: This trial of DSO supplemented with ripasudil included local and systemic safety analysis. We judge that this treatment option is emerging as a reliable intervention for select patients with Fuchs' Endothelial Corneal Dystrophy (FECD) with an acceptable safety profile. The observation of relapse edema is strong evidence of a drug effect. The longevity of these results remains unknown.

This prospective, randomized controlled trial study compared the effects of four dressings for adult partial thickness burns, focusing on re-epithelialization time and cost effectiveness. Adults with partial thickness burns meeting inclusion criteria were randomized to either Biobrane™, Acticoat™, Mepilex® Ag, or Aquacel® Ag. Primary endpoint for analysis was >95% re-epithelialization. Incremental cost-effectiveness ratios were calculated based on dressing costs. Dominance probabilities between treatment arms were calculated from bootstrap resampling trial data. One hunderd thirty-one partial thickness burn wounds in 119 patients were randomized. Adjusting for sex, age, smoking status, burn mechanism, TBSA, and first aid adequacy, Mepilex® Ag had a reduced time to re-epithelialization compared to Biobrane™ (IRR: 1.26; 95% CI: 1.07-1.48, P < .01). Economic analysis showed that there was a 99%, 71%, and 53% probability that Mepilex® Ag dominated (cheaper and more effective) Biobrane™, Acticoat™, and Aquacel® Ag, respectively. Mepilex® Ag achieved faster re-epithelialization and better cost effectiveness. Patient satisfaction and comfort seems better with Biobrane™ although not reflected within the end outcome of the healed wound. It is the patients' (after extensive education) and clinicians' choice, level of experience, and availability of products in praxis that will guide the decision as to which the product is used individually on which patient.

Importance: Although international guidelines recommend use of the Global Registries of Acute Coronary Events (GRACE) risk score (GRS) to guide acute coronary syndrome (ACS) treatment decisions, the prospective utility of the GRS in improving care and outcomes is unproven. Objective: To assess the effect of routine GRS implementation on guideline-indicated treatments and clinical outcomes of hospitalized patients with ACS. Design, Setting, and Participants: Prospective cluster (hospital-level) randomized open-label blinded end point (PROBE) clinical trial using a multicenter ACS registry of acute care cardiology services. Fixed sampling of the first 10 patients within calendar month, with either ST-segment elevation or non-ST-segment elevation ACS. The study enrolled patients from June 2014 to March 2018, and data were analyzed between February 2020 and April 2020. Interventions: Implementation of routine risk stratification using the GRS and guideline recommendations. Main Outcomes and Measures: The primary outcome was a performance score based on receipt of early invasive treatment, discharge prescription of 4 of 5 guideline-recommended pharmacotherapies, and cardiac rehabilitation referral. Clinical outcomes included a composite of all-cause death and/or myocardial infarction (MI) within 1 year. Results: This study enrolled 2318 patients from 24 hospitals and was stopped prematurely owing to futility. Of the patients enrolled, median age was 65 years (interquartile range, 56-74 years), 29.5% were women (n = 684), and 62.9% were considered high risk (n = 1433). Provision of all 3 measures among high-risk patients did not differ between the randomized arms (GRS: 424 of 717 [59.9%] vs control: 376 of 681 [55.2%]; odds ratio [OR], 1.04; 95% CI, 0.63-1.71; P = .88). The provision of early invasive treatment was increased compared with the control arm (GRS: 1042 of 1135 [91.8%] vs control: 989 of 1183 [83.6%]; OR, 2.26; 95% CI, 1.30-3.96; P = .004). Prescription of 4 of 5 guideline-recommended pharmacotherapies (GRS: 864 of 1135 [76.7%] vs control: 893 of 1183 [77.5%]; OR, 0.97; 95% CI, 0.68-1.38) and cardiac rehabilitation (GRS: 855 of 1135 [75.1%] vs control: 861 of 1183 [72.8%]; OR, 0.68; 95% CI, 0.32-1.44) were not different. By 12 months, GRS intervention was not associated with a significant reduction in death or MI compared with the control group (GRS: 96 of 1044 [9.2%] vs control: 146 of 1087 [13.4%]; OR, 0.66; 95% CI, 0.38-1.14). Conclusions and Relevance: Routine GRS implementation in cardiology services with high levels of clinical care was associated with an increase in early invasive treatment but not other aspects of care. Low event rates and premature study discontinuation indicates the need for further, larger scale randomized studies. Trial Registration: anzctr.org.au Identifier: ACTRN12614000550606.

BACKGROUND: Healthy controls exhibit spontaneous and positional nystagmus which needs to be distinguished from pathological nystagmus. OBJECTIVE: Define nystagmus characteristics of healthy controls using portable video-oculography. METHODS: One-hundred and one asymptomatic community-dwelling adults were prospectively recruited. Participants answered questions regarding their audio-vestibular and headache history and were sub-categorized into migraine/non-migraine groups. Portable video-oculography was conducted in the upright, supine, left- and right-lateral positions, using miniature take-home video glasses. RESULTS: Upright position spontaneous nystagmus was found in 30.7% of subjects (slow-phase velocity (SPV)), mean 1.1±2.2 degrees per second (°/s) (range 0.0 - 9.3). Upright position spontaneous nystagmus was horizontal, up-beating or down-beating in 16.7, 7.9 and 5.9% of subjects. Nystagmus in at least one lying position was found in 70.3% of subjects with 56.4% showing nystagmus while supine, and 63.4% in at least one lateral position. While supine, 20.8% of subjects showed up-beating nystagmus, 8.9% showed down-beating, and 26.7% had horizontal nystagmus. In the lateral positions combined, 37.1% displayed horizontal nystagmus on at least one side, while 6.4% showed up-beating, 6.4% showed down-beating. Mean nystagmus SPVs in the supine, right and left lateral positions were 2.2±2.8, 2.7±3.4, and 2.1±3.2°/s. No significant difference was found between migraine and non-migraine groups for nystagmus SPVs, prevalence, vertical vs horizontal fast-phase, or low- vs high-velocity nystagmus (<5 vsâ>â5°/s). CONCLUSIONS: Healthy controls without a history of spontaneous vertigo show low velocity spontaneous and positional nystagmus, highlighting the importance of interictal nystagmus measures when assessing the acutely symptomatic patient.
