Abstract
AIM This study aims to explore regional variation and identify regions within Australia with high incidence of out-of-hospital cardiac arrest (OHCA) and low rates of bystander cardiopulmonary resuscitation (CPR). METHOD Adult OHCAs of presumed medical aetiology occurring across Australia between 2017 and 2019 were mapped onto local government areas (LGA) using the location of arrest coordinates. Bayesian spatial models were applied to provide "smoothed" estimates of OHCA incidence and bystander CPR rates (for bystander-witnessed OHCAs) for each LGA. For each state and territory, high-risk LGAs were defined as those with an incidence rate greater than the state or territory's 75th percentile and a bystander CPR rate less than the state or territory's 25th percentile. RESULTS A total of 62,579 OHCA cases attended by emergency medical services across 543 LGAs nationwide were included in the study. Nationally, the OHCA incidence rate across LGA ranged from 58.5 to 198.3 persons per 100,000, while bystander CPR rates ranged from 45% to 75%. We identified 60 high-risk LGAs, which were predominantly located in the state of New South Wales. Within each region, high-risk LGAs were typically located in regional and remote areas of the country, except for four metropolitan areas-two in Adelaide and two in Perth. CONCLUSIONS We have identified high-risk LGAs, characterised by high incidence and low bystander CPR rates, which are predominantly in regional and remote areas of Australia. Strategies for reducing OHCA and improving bystander response may be best targeted at these regions.

Abstract
Depression and heart failure frequently occur together, symptoms overlap and the prognosis is worsened. Both conditions share biopsychosocial risk factors and are accompanied by behavioural/lifestyle, neurohormonal, inflammatory and autonomic changes that are implicated aetiologically. Depression has been conceptualized as a decompensated response to allostatic overload, wherein adaptive psychological, behavioural and physiological responses to chronic and/or severe stress, become unsustainable. Heart failure can similarly be viewed as a decompensated response to circulatory overload, wherein adaptive functional (neurohormonal effects on circulation, inotropic effects on heart) and structural (myocardial remodelling) changes, become unsustainable. It has been argued that the disengaged state of depression can initially be protective, limiting an individual's exposure to external challenges, such that full recovery is often possible. In contrast, heart failure, once past a tipping-point, can progress relentlessly. Here, we consider the bidirectional interactions between depression and heart failure. Targeted treatment of depression in the context of heart failure may improve quality of life, yet overall benefits on mortality remain elusive. However, effective treatment of heart failure typically enhances function and improves key psychological and behavioural determinants of low mood. Prospectively, research that examines the mechanistic associations between depression and heart failure offers fresh opportunity to optimize personalized management in the advent of newer interventions for both conditions.

Abstract
CONTEXT Distraction therapies are widely used in emergency departments to manage pediatric pain and distress. Little is known about which distraction techniques would translate best into the prehospital environment. OBJECTIVE To identify emergency department-based distraction techniques for managing pain and/or distress in pediatric patients who may be suitable for the prehospital environment. DATA SOURCES Ovid Medline, Embase, CINAHL, Cochrane library, World Health Organization Clinical Trials Registry and Google Scholar were searched from their beginning to May 2022. STUDY SELECTION Studies were included if they reported on: (1) distraction techniques, (2) pediatric ED patients, (3) with pain and/or distress, and (4) used interventional or observational study designs. Studies utilizing interventions not feasible in the prehospital setting were excluded. DATA EXTRACTION Three authors independently assessed eligibility and completed data extraction. RESULTS The search yielded 4516 records, and 29 studies were included. Risk of bias across all studies was moderate to high. Children were 3 months to 18 years old. Digital, nondigital, and environmental distractors were tested using 12 pain and 15 distress measurement tools. No significant negative outcomes were reported. Fifteen studies reported reductions in self-reported pain and/or distress. Active, nondigital distractors most consistently reduced pain. There was insufficient evidence to support a distraction type for distress. LIMITATIONS The heterogeneity in study design, distractors, measurement tools, and reporting restricted statistical analysis. CONCLUSIONS Distraction tools that effectively reduce pediatric pain and/or distress in the ED exist and could be adapted to the prehospital environment. Further research is required to determine feasibility and effectiveness.

The development of a risk-adjustment strategy to benchmark emergency medical service (EMS) performance in relation to out-of-hospital cardiac arrest in Australia and New Zealand. Resuscitation 2023:109847. [PMID: 37211232 DOI: 10.1016/j.resuscitation.2023.109847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/24/2023] [Accepted: 05/13/2023] [Indexed: 05/23/2023]
Abstract
INTRODUCTION The aim of this study was to develop a risk adjustment strategy, including effect modifiers, for benchmarking emergency medical service (EMS) performance for out-of-hospital cardiac arrest (OHCA) in Australia and New Zealand. METHOD Using 2017-2019 data from the Australasian Resuscitation Outcomes Consortium (Aus-ROC) OHCA Epistry, we included adults who received an EMS attempted resuscitation for a presumed medical OHCA. Logistic regression was applied to develop risk adjustment models for event survival (return of spontaneous circulation at hospital handover) and survival to hospital discharge/30 days. We examined potential effect modifiers, and assessed model discrimination and validity. RESULTS Both OHCA survival outcome models included EMS agency and the Utstein variables (age, sex, location of arrest, witnessed arrest, initial rhythm, bystander cardiopulmonary resuscitation, defibrillation prior to EMS arrival, and EMS response time). The model for event survival had good discrimination according to the concordance statistic (0.77) and explained 28% of the variation in survival. The corresponding figures for survival to hospital discharge/30 days were 0.87 and 49%. The addition of effect modifiers did little to improve the performance of either model. CONCLUSION The development of risk adjustment models with good discrimination is an important step in benchmarking EMS performance for OHCA. The Utstein variables are important in risk-adjustment, but only explain a small proportion of the variation in survival. Further research is required to understand what factors contribute to the variation in survival between EMS.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
INTRODUCTION The Australasian Resuscitation Outcomes Consortium (Aus-ROC) out-of-hospital cardiac arrest (OHCA) Epistry (Epidemiological Registry) now covers 100% of Australia and New Zealand (NZ). This study reports and compares the Utstein demographics, arrest characteristics and outcomes of OHCA patients across our region. METHODS We included all OHCA cases throughout 2019 as submitted to the Epistry by the eight Australian and two NZ emergency medical services (EMS). We calculated crude and age-standardised incidence rates and performed a national and EMS regional comparison. RESULTS We obtained data for 31,778 OHCA cases for 2019: 26,637 in Australia and 5,141 in NZ. Crude incidence was 107.9 per 100,000 person-years in Australia and 103.2/100,000 in NZ. Overall, the majority of OHCAs occurred in adults (96%), males (66%), private residences (76%), were unwitnessed (63%), of presumed medical aetiology (83%), and had an initial monitored rhythm of asystole (64%). In non-EMS-witnessed cases, 38% received bystander CPR and 2% received public defibrillation. Wide variation was seen between EMS regions for all OHCA demographics, arrest characteristics and outcomes. In patients who received an EMS-attempted resuscitation (13,664/31,778): 28% (range across EMS=13.1% to 36.7%) had return of spontaneous circulation (ROSC) at hospital arrival and 13% (range across EMS=9.9% to 20.7%) survived to hospital discharge/30-days. Survival in the Utstein comparator group (bystander-witnessed in shockable rhythm) varied across the EMS regions between 27.4% to 42.0%. CONCLUSION OHCA across Australia and NZ has varied incidence, characteristics and survival. Understanding the variation in survival and modifiable predictors is key to informing strategies to improve outcomes.

Impact of a mass media campaign on presentations and ambulance use for acute coronary syndrome. Open Heart 2021; 8:openhrt-2021-001792.

Abstract
Objective Between 2009 and 2013, the National Heart Foundation of Australia ran mass media campaigns to improve Australian’s awareness of acute coronary syndrome (ACS) symptoms and the need to call emergency medical services (EMS). This study examined the impact of this campaign on emergency department (ED) presentations and EMS use in Victoria, Australia. Methods The Victorian Department of Health and Human Services provided data for adult Victorian patients presenting to public hospitals with an ED diagnosis of ACS or unspecified chest pain (U-CP). We modelled changes in the incidence of ED presentations, and the association between the campaign period and (1) EMS arrival and (2) referred to ED by a general practitioner (GP). Models were adjusted for increasing population size, ACS subtype and demographics. Results Between 2003 and 2015, there were 124 632 eligible ED presentations with ACS and 536 148 with U-CP. In patients with ACS, the campaign period was associated with an increase in ED presentations (incidence rate ratio: 1.11; 95% CI 1.07 to 1.15), a decrease in presentations via a GP (adjusted OR (AOR): 0.77; 95% CI 0.70 to 0.86) and an increase in EMS use (AOR: 1.10; 95% CI 1.05 to 1.17). Similar, but smaller associations were seen in U-CP. Conclusions The Warning Signs Campaign was associated with improvements in treatment seeking in patients with ACS—including increased EMS use. The increase in ACS ED presentations corresponds with a decrease in out-of-hospital cardiac arrest over this time. Future education needs to focus on improving EMS use in ACS patient groups where use remains low.

Abstract
BACKGROUND The emergency department (ED) plays an important role in out-hospital-cardiac arrest (OHCA) management. However, ED outcomes are not widely reported. This study aimed to (1) describe OHCA ED outcomes and reasons for ED deaths, and (2) whether these differed between hospitals. METHODS Data were obtained from the Victorian Ambulance Cardiac Arrest Registry and 12 hospitals for adult, non-traumatic OHCA cases transported to ED between 2014 and 2016. Multivariable logistic regression was used to examine the association of level of cardiac arrest centre on ED survival in a subset of cases (non-paramedic witnessed OHCA who were unconscious on ED arrival with ROSC). RESULTS Of 1547 eligible OHCA cases, 81% (N = 1254) survived ED, varying between 57% to 88% between EDs. Among non-survivors, the majority had either: cessation of resuscitation after presenting with CPR in progress (27%); withdrawal of life-sustaining treatment for non-neurological (n = 65, 22%) or neurological (16%) reasons; or a unsuccessful resuscitation following a rearrested in ED (20%). These causes of ED deaths varied between the different levels of cardiac arrest centres, and in our subset of interest (n = 952) ED survival was associated with transportation to centres with high annual OHCA volumes and with 24-hour cardiac intervention capabilities (AOR = 3.43, 95% CI 1.89-6.21). CONCLUSION Our study found wide variation in survival between EDs, which was associated with hospital characteristics. Such data suggests the need for a detailed review of ED deaths, particularly in non-cardiac arrest centres, and potentially the need for monitoring ED survival as a measure of quality.

Abstract
Abstract
Introduction
Traumatic Brain Injury (TBI) is frequently associated with problems with sleep and diurnal somnolence. After determining if subjective somnolence was associated with sleep disturbances, we investigated if alterations in sleep architecture were associated with cognitive, social and emotional health in a sex dependent manner. For patients receiving positive airway pressure (PAP) treatment, we determined if lack of compliance contributed to cognitive and quality of life issues.
Methods
Adult TBI subjects (n=57) were assessed via overnight polysomnography. Mean age was 41 years and mean TBI chronicity was 2.5 years. Overall level of disability was determined by the Mayo Portland Inventory II. Sleep measures included slow wave sleep (SWS), REM latency, percent time in all sleep stages, apnea/hypopnea index, wake after sleep onset (WASO), and arousal index. Outcome measures were the California Verbal Learning Test (CVLT), Montreal Cognitive Assessment (MoCA), Trails A and B, Beck Depression Inventory, and Neuro-QoL.
Results
No sex effects for reporting somnolence were found. Besides being associated with increased subjective anxiety and stigma, somnolence was associated with increased arousals, decreases in SWS and higher incidence of REM AHI. WASO and number of arousals had a negative impact on the amount of SWS and sleep efficiency. Men spent significantly more time in REM sleep, which was correlated with higher scores on the MoCA and CVLT. Women showed more disability. Longer latencies to SWS were associated with increased CVLT performance. AHI was associated with increases in emotional/behavioral dyscontrol, fatigue and self-reported sleep disturbance. All effects were statistically significant.
Conclusion
Female TBI patients show significant impairments in REM sleep, which may impact learning and memory. Sleep disturbances were associated with poorer cognitive performance and may ultimately affect outcome, as indicated by lower scores on quality of life measures.

Abstract
Objective: To explore the prevalence of micronutrient deficiencies in patients with diabetic foot ulcers and correlate this with foot disease severity and other clinical factors. Approach: Prospective cohort study of diabetic patients with foot ulcers seen in multidisciplinary foot clinics across Adelaide or admitted to the Vascular Surgery Unit at the Royal Adelaide Hospital between February 2017 and September 2018. A total of 131 patients were included in the study. Plasma serum levels of vitamins A, C, D, and E, copper, zinc, and ferritin were measured. Demographic and clinical data, including BMI, smoking status, duration of diabetes, HbA1c, and WIfI score, were obtained. Results: The most prevalent nutritional deficiency found was vitamin D affecting 55.7% of patients. Suboptimal levels of vitamin C affected 73% of patients, comprising marginal levels in 22.2% and deficient levels in 50.8%. Zinc deficiency, vitamin A deficiency, and low ferritin levels were present in 26.9%, 10.9%, and 5.9% of patients, respectively. There was no correlation between BMI, grip strength, duration of diabetes, HbA1c, or smoking status with micronutrient deficiency. Increased severity of diabetic foot disease was associated with lower vitamin C levels (p = 0.02). Innovation: This study has demonstrated that the deficiency of micronutrients, especially vitamin D, vitamin C, zinc, and vitamin A, is common in diabetic patients with foot ulcers. Conclusions: The prevalence of micronutrient deficiency is high in a diabetic population with foot ulcers/wounds. Special concerns regarding the high prevalence of vitamin C and zinc deficiency, given their roles in wound healing. Although further research needs to be performed to determine the clinical implications of our findings, micronutrient deficiency should be considered in diabetic patients with foot wounds.

Abstract
BACKGROUND Uterovaginal prolapse is a prevalent gynaecological issue, which can have a negative impact on the quality of life of women. Hysterectomy and vaginal repair are conventional treatments to address apical prolapse; however, women are increasingly requesting uterine-preserving alternatives. AIMS This study aimed to evaluate the impact of laparoscopic mesh sacrohysteropexy on symptomatic prolapse from an Australian experience. MATERIALS AND METHODS This retrospective cohort study presents outcomes of 157 patients who underwent laparoscopic mesh sacrohysteropexy at a private practice in South Australia during 2007-2017. Primary outcome is the success rate according to the pelvic organ prolapse quantification (POP-Q) system. Secondary measures included complication rates and patients identified as having Stages III-IV prolapse and their outcomes. RESULTS The median age was 58 years (27-86 years), median parity was 2 (0-6), and median body mass index was 26.8 (23-29.9). One hundred and thirty-four women had a laparoscopic hysteropexy and concurrent vaginal prolapse repair and four women had an isolated laparoscopic hysteropexy. The mean pre-operative point C was 0.60. The mean change from pre-operative point C to post-operative point C was 7.6 cm (P < 0.01). Of the 136 patients (98.6%) seen at post-operative 4-6 weeks, all had Stage 0 POP-Q scores. Prolapse recurrence was observed in 22 patients, while 116 patients remained cured at their last follow-up. Prolapse recurrence was associated with anterior vaginal mesh, previous prolapse surgery, pre-operative Stage III-IV disease and number of vaginal deliveries. CONCLUSIONS Laparoscopic mesh sacrohysteropexy is an effective and safe procedure with a high success rate comparable to available international data.

Abstract
Abstract
Background
Sex-based differences in sudden cardiac death (SCD) exist and screening methods for SCD are inadequate.
Purpose
To develop sex-specific lifetime risk prediction models using electrocardiographic (ECG) global electrical heterogeneity (GEH) and clinical characteristics.
Methods
Participants from the Atherosclerosis Risk in Communities study with analyzable ECGs (n=14,725; age, 54.2±5.8 yrs; 55% female, 74% white) were followed up for 24.4 years (median). Traditional ECG and GEH variables were measured on 12-lead ECGs. A Cox regression model was used to develop a prediction model. In women, the final model included race, age, coronary heart disease (CHD), stroke, hypertension, diabetes, smoking, high-density lipoprotein, albumin, uric acid, education level, heart rate, QTc, sum absolute QRST integral, spatial peak QRS-T angle. In men, the final prediction model included age, race, CHD, stroke, hypertension, diabetes, total cholesterol, physical activity, smoking, serum phosphorus, albumin, chronic kidney disease, spatial area QRS-T angle, area spatial ventricular gradient (SVG) elevation and magnitude, and peak SVG magnitude.
Results
There were a total of 530 SCDs. Our prediction models showed robust prediction of SCD in both sexes [(Harrell's C-statistic women 0.863 (95% CI 0.845–0.882), men 0.786 (95% CI 0.786–0.803)]. In women when ECG and GEH variables were added to clinical variables, the net reclassification improved by 9% (P=0.001) (Table). In men there was no significant reclassification improvement.

Conclusions
We were the first to develop sex-specific lifetime SCD prediction models. The addition of ECG GEH to clinical variables improved SCD risk reclassification in women, but not in men. Prediction of SCD was more accurate in women as compared to men.

Abstract
Mutations in proline-rich transmembrane protein 2 (PRRT2) cause a range of episodic disorders that include paroxysmal kinesigenic dyskinesia and benign familial infantile epilepsy. Mutations are generally loss of function and include the c649dupC frameshifting mutation that is present in around 80% of affected individuals. To investigate how Prrt2 loss of function mutations causes disease, we performed a phenotypic investigation of a transgenic Prrt2 knockout (Prrt2 KO) mouse. We observed spontaneous paroxysmal episodes with behavioural features of both seizure and movement disorders, as well as unexplained deaths in KO and HET animals. KO mice showed spatial learning deficits in the Morris water maze, as well as gait abnormalities in the quantitative Digigait analysis; both of which may be representative of the more severe phenotypes experienced by homozygous patients. These findings extend the described phenotypes of Prrt2 mutant mice, further confirming their utility for in vivo investigation of the role of Prrt2 mutations in episodic diseases.

Abstract
IMPORTANCE This study assesses the interobserver agreement on dacryocystography (DCG) and dacryoscintigraphy (DSG) findings. BACKGROUND There are no standard grading criteria to guide the interpretation of conventional DCG and DSG findings and therefore there may be a degree of subjectivity. This study evaluates the level of interobserver agreement in the interpretation of DCG and DSG findings. DESIGN A retrospective observational study at the Royal Adelaide Hospital. PARTICIPANTS A total of 165 patients who presented with epiphora with 276 DCGs and 290 DSGs performed were included in this study. METHODS DCG and DSG images were obtained, anonymized, randomized and interpreted by three independent oculoplastic surgeons. Standard grading criteria were set for both DCG and DSG images. Data from all observers were analysed for interobserver agreement using Kappa (κ) statistics, generated using a variation of Cohen's kappa for multiple observers. MAIN OUTCOME MEASURES Level of interobserver agreement (κ values) in the grading of DCG and DSG findings. RESULTS There was an overall moderate interobserver agreement for DCG findings (κ = 0.55), with the highest agreement on interpreting canalicular obstruction (κ = 0.80), followed by proximal nasolacrimal duct obstruction (κ = 0.67) and normal patency (κ = 0.63). There was an overall fair interobserver agreement for DSG findings (κ = 0.36), with the best being moderate agreement (κ = 0.42-0.50) for interpreting pre-sac delay and post-sac proximal delay. CONCLUSIONS AND RELEVANCE DCG offers good reliability in interpreting patent and obstructed systems. On the other hand, DSG has poor agreement and highlights some of the limitations in the ability to guide epiphora management.

Reduced aquaporin-1 transcript expression in colorectal carcinoma is associated with promoter hypermethylation. Epigenetics 2019; 14:158-170.

Abstract
Aquaporin-1 (AQP1) is a homo-tetrameric transmembrane protein that facilitates rapid movement of water and ions across cell membranes. The clinical significance of AQP1 expression in colorectal carcinoma (CRC) is controversial. The aim of this study was to investigate the prognostic significance of AQP1 transcript expression and the association between expression and promoter methylation in normal colonic mucosa, CRC tissues and cell lines. Analysis of publicly available datasets from The Cancer Genome Atlas revealed that AQP1 expression was significantly decreased in CRC compared to normal mucosa (12.7 versus 33.3 respectively, P < 0.0001). However, expression increased with advanced disease, being significantly higher in stage IV (17.6) compared to either stage I (11.8, P = 0.0039) or II (10.9; P = 0.0023), and in patients with lymph node metastasis compared to those without (13.9 versus 11.3 respectively, P = 0.0023). Elevated expression was associated with decreased overall survival with univariate (Cox Proportional Hazard Ratio 1.60, 95% confidence interval 1.05-2.42, P = 0.028), but not multivariable analysis when considering the confounders stage and age. Analysis of HumanMethylation450 data demonstrated that AQP1 promoter methylation was significantly increased in CRC compared to normal mucosa. Analysis of CRC tissues and cell lines strongly suggested that methylation was associated with decreased expression. BRAFV600E mutation alone did not explain the increase in methylation. In conclusion, AQP1 transcript expression was decreased in CRC compared to normal mucosa, and this was associated with AQP1 promoter hypermethylation. AQP1 transcript expression increased with advanced disease but was not an independent prognostic indicator.

Abstract
There are limited and inconsistent data suggesting that mild iodine deficiency in pregnancy might be associated with poorer developmental outcomes in children. Between 2011 and 2015, we conducted a prospective cohort study in Australia examining the relationship between maternal iodine intake in pregnancy and childhood neurodevelopment, assessed using Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), in 699 children at 18 months. Maternal iodine intake and urinary iodine concentration (UIC) were assessed at study entry (<20 weeks' gestation) and at 28 weeks' gestation. Maternal iodine intake in the lowest (<220 μg/day) or highest (≥391 μg/day) quartile was associated with lower cognitive, language, and motor scores (mean differences ranged from 2.4 (95% confidence interval (CI): 0.01, 4.8) to 7.0 (95% CI: 2.8, 11.1) points lower) and higher odds (odds ratios ranged from 2.7 (95% CI: 1.3, 5.6) to 2.8 (95% CI: 1.3, 5.7)) of cognitive developmental delay (Bayley-III score <1 SD) compared with mothers with an iodine intake in the middle quartiles. There was no association between UIC in pregnancy and Bayley-III outcomes regardless of whether UIC and the outcomes were analyzed as continuous or categorical variables. Both low and high iodine intakes in pregnancy were associated with poorer childhood neurodevelopment in this iodine-sufficient population.

Abstract
Tranexamic acid (TA) is widely reported to reduce bleeding and the risk of blood transfusion in patients undergoing lower limb arthroplasty. No study in this setting has had adequate power to examine for the effect of TA on either uncommon, but clinically important, adverse events or patient-centric endpoints. A large randomised controlled trial (RCT) is required to address these questions. As a preliminary feasibility study, we conducted an investigator-initiated, prospective, randomised, double blind placebo-controlled trial in 140 patients, aged 45 years or older, undergoing elective primary or revision hip or knee joint replacement. Subjects were randomised to receive intravenous (IV) TA or a placebo. The primary endpoints were the proportion of patients receiving allogenic blood transfusion and the feasibility of extending our trial methodology to a large trial of TA in this population. Secondary endpoints included a range of adverse clinical and surgical events as well as several patient-centric questionnaires. Red blood cell transfusion occurred in 15% of all patients prior to discharge from hospital. Transfusion rates were significantly different between the TA and placebo groups (8.5% versus 21.7%, <i>P</i>=0.03). Three out of four feasibility endpoints were met, with recruitment being slower than expected. No significant differences were seen between groups in the secondary endpoints. Despite a lower rate of transfusion than that widely reported, IV TA reduced transfusion in patients undergoing lower limb arthroplasty. Our trial methodology would be feasible in the setting of a large multicentre study to investigate whether TA is safe and reduces bleeding in lower limb arthroplasty.

Abstract
Background Distal radial fractures are one of the most common orthopaedic cases that present to the A&E department. Surgical intervention is warranted in displaced intraarticular fractures and fractures with more than the recommended angulation or shortening, and is most commonly treated with volarly placed fixed angle locking plates. The aim of this study is to determine and compare the efficacy of two different plates for surgical treatment of distal radius fractures. The VRP 2.0 is a new plate produced by the Austofix company and this system will be compared against the VA-LP (Variable angle-locking plate) produced by Depuy-Synthes which has been used as the standard treatment device. Methods and Design Patients between the ages of 18 and 80 presenting to the Royal Adelaide Hospital with isolated closed distal radial fractures will be invited to participate in this study. A total of 200 patients are required to provide 90% statistical power at a 5% alpha level to detect a difference of 11.5 points on the PRWE (Patient rated Wrist evaluation) score. The primary outcome measure will be the PRWE score while the secondary outcome measures will include the DASH score, EQ5D score, clinical range of movements, grip strength as well as patient perceived return of function at the wrist and time to resumption to work. These will be measured at 6 weeks, 3 months and 12 months. Radiographic indices including the radial tilt, length, volar inclination and plate prominence will also be measured. Complications will be recorded up to 12 months. Post hoc comparisons will be done using paired t tests. An intention to treat and a per protocol analysis will be done to compare the 2 groups. Discussion Distal radial fractures are increasingly being treated by internal fixation using volar locking plates. However, there is no prospective study to date comparing one plate against another in terms of outcome and complications. This study could provide more information about the best way to treat these injuries surgically. Trial registration The trial is registered with the Australia New Zealand Clinical Trials Registry (ANZCTR). Trial registration date-17/11/2016. Trial registration number-ACTRN12616001590459.

Abstract
AIM This paper presents the prevalence of antiepileptic polytherapy at a single tertiary institution and systematically reviews the evidence base for its efficacy and neurobehavioural safety in children. METHOD Prevalence of antiepileptic polypharmacy was determined from pharmacy dispensing records at a paediatric tertiary hospital and neurobehavioural comorbidities quantified through casenote review; comparison is made with studies evaluating the neurobehavioural safety of antiepileptic polytherapy, identified via systematic literature review. RESULTS Amongst 262 patients at the hospital, 117 (44.7%) were prescribed polytherapy; with patients having an intellectual disability statistically more likely to be prescribed polytherapy than those without (70.5% vs 40.6%; p < 0.0001). Systematic review identified no trials addressing the efficacy or neurobehavioural outcomes of polytherapy as a primary outcome. Several observational studies identified associations between polytherapy and neurobehavioural adverse outcomes such as anxiety and behavioural disturbance. Observational studies also suggest that a reduction in polytherapy load is generally not associated with worsening seizure control. CONCLUSION Whilst antiepileptic polytherapy is common practice within paediatric epilepsy cohorts attending tertiary care institutions, evidence is lacking to support its efficacy. There are significant practical difficulties to undertaking randomised controlled trials within this population. Nonetheless, clinicians must consider that adverse neurobehavioural consequences of polytherapy might outweigh benefits to seizure control.

Abstract
ObjectiveCoronary vasodilator function and atherosclerotic plaque progression have both been shown to be associated with adverse cardiovascular events. However, the relationship between these factors and the lipid burden of coronary plaque remains unknown. These experiments focus on investigating the relationship between impaired coronary vasodilator function (endothelium dependent (salbutamol) and endothelium independent (glyceryl trinitrate)) and the natural history of atheroma plaque progression and lipid burden using dual modality intravascular ultrasound (IVUS) and near-infrared spectroscopy (NIRS) imaging.Methods33 patients with stable chest pain or acute coronary syndrome underwent serial assessment of coronary vasodilator function and intracoronary plaque IVUS and NIRS imaging. Coronary segmental macrovascular response (% change segmental lumen volume (ΔSLV)), plaque burden (per cent atheroma volume (PAV)), lipid core (lipid-rich plaque (LRP) and lipid core burden index (LCBI)) were measured at baseline and after an interval of 12–18 months (n=520 segments).ResultsLipid-negative coronary segments which develop into LRP over the study time period demonstrated impaired endothelial-dependent function (−0.24±2.96 vs 5.60±1.47%, P=0.04) and endothelial-independent function (13.91±4.45 vs 21.19±3.19%, P=0.036), at baseline. By multivariate analysis, endothelial-dependent function predicted ∆LCBI (β coefficient: −3.03, 95% CI (−5.81 to −0.25), P=0.033) whereas endothelial-independent function predicted ∆PAV (β coefficient: 0.07, 95% CI (0.04 to 0.10), P<0.0001).ConclusionsEpicardial coronary vasodilator function is a determinant of future atheroma progression and composition irrespective of the nature of clinical presentation.Trial registration numberACTRN12612000594820, Post-results.

Abstract
Background Sugammadex is used for the rapid reversal of neuro muscular block. It was used on an unrestricted basis in our facility prior to July 2014 but has subsequently been restricted due to the removal of cost subsidies. Our aim is to determine the impact of restricting the use of Sugammadex on clinical outcomes. Methods A retrospective audit was conducted for the period January 1st to December 31st 2014. Sugammadex use was unrestricted during the first 6 months of this period and restricted over the following period. Patients who had endotracheal intubation for any surgery were included in the audit. Non- intubated patients, patients with incomplete data and patients who were intubated and transferred to the intensive care unit were excluded. The Operating Room Information System and medical records were used to obtain information on the operating theatre time, post-anesthesia care unit time and side effects such as postoperative nausea and vomiting, oxygen-de-saturation during recovery and anaphylaxis; Sugammadex usage and cost data obtained from the hospital pharmacy. Results 1347 and 1302 patients were included for the unrestricted and restricted periods, respectively. There were no significant differences between the time periods with respect to patient characteristics (Age, ASA) or side effects (oxygen de-saturation, nausea). While mean time in theatre was similar across the time periods, mean recovery time was significantly longer during the restricted period (P < 0.0001). One case of anaphylaxis was reported during the restricted period while no cases occurred during the unrestricted period. Median Sugammadex dose was 200 mg and its usage dropped by 54% in the restricted time. The cost of sugammadex was $180 AUD and Neostigmine $1.80 AUD. Conclusions Though unrestricting Sugammadex reduced recovery time but has had minimal impact on other clinical outcomes. Neostigmine represents a cheaper alternative and its use remains standard practice in our facility.

Abstract
Abstract
Background:
SIRT is a globally licensed technique of Radio-Embolization (RE) of hepatic tumors via intra-arterial infusion of β-particle emitting Yttrium-90 (Y-90) radio-labelled microspheres. It increases response rates and hepatic time to progression in metastatic colorectal cancer when used in combination with 5FU/Oxaliplatin (FOLFOX) chemotherapy with acceptable toxicity profile. FOLFOX gives a radio-sensitizing effect and also controls disease outside the liver. Breast cancer liver metastases (BCLM) patients often have extra-hepatic disease and respond to multiple lines of systemic therapy and SIRT is infrequently used.
Methods and patients
Between 2010 and 2016 we treated 25 BCLM patients with Y-90 SIRT.
Receptor status: 20 ER+ve/HER-2 -ve, 3 ER-ve/HER-2 +ve, 2 triple -ve.
Eleven patients had liver only disease with 14 also having known extra-hepatic disease. Average number of previous lines of therapy in metastatic setting: chemotherapy = 2.4; endocrine = 1. Sixty-four % patients had prior Capecitabine (n=16); 12% platinum (n=3, all Carboplatin). Twenty patients received chemotherapy with SIRT: 17 had modified FOLFOX6 (Oxaliplatin/bolus 5FU day1, infusional 5FU day 1-3 (46 hrs); 3 patients had Modified de Gramont style 5FU alone. Five patients had no chemotherapy.
Sir-spheres were inserted on day 2 of FOLFOX with the 5FU infusion pump continuing to day 3. Further 2-weekly FOLFOX chemo cycles were at clinician's discretion: average number delivered 3.8. Four patients had the liver treated in two halves, approximately 6 weeks apart. One patient received SIRT only to half the liver. Patients were imaged with PET-CT/CT before and 2-3 months after SIRT. Retrospective case note review was performed and data correlated to evaluate tumor response (RR); hepatic and extra hepatic progression free survival (HPFS and EHPFS) and overall survival (OS). Accurate toxicity data was not recorded.
Results
Hepatic CT response rates: PR 56% (n=14), SD 28% (n=7) and PD 16% (n=4). Hepatic PET response rates: CR 32% (n=8), PR 40% (n=10), SD 12% (n=3), PD 16%(n=4). (Overall PET liver disease control rate = 84%).
Eight patients (32%) had extra-hepatic PD at first assessment. Of them, 4 had PR, 2 SD and 2 PD in the liver at that assessment. Two HER-2 +ve patients had brain metastases as first sign of PD within 75 days, an area not previously screened. Of 16 pre-treated with Capecitabine, liver CT response rates: 62.5% PR, 18.75% SD (n=10,3). Post SIRT/FOLFOX, average number of therapy lines: 2 for chemo and 0.75 for endocrine, with 8 patients still alive at time of censoring.
Median OS: 766 HPFS: 210 days (CI 140-286). Median EHPFS in patients with extra-hepatic disease: 152 days (CI 96-636).
Conclusions
SIRT with FOLFOX in previously treated BCLM patients produces high response rates, excellent tumor control and time to progression in the liver with good overall survival. It does not seem to decrease the ability to give further lines of chemotherapy and can be considered as an option for breast cancer patients with liver metastases.

A systematic review: efficacy of botulinum toxin in walking and quality of life in post-stroke lower limb spasticity. Syst Rev 2018; 7:1. [PMID: 29304876 PMCID: PMC5755326 DOI: 10.1186/s13643-017-0670-9] [Citation(s) in RCA: 73] [Impact Index Per Article: 12.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2017] [Accepted: 12/20/2017] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Improved walking is one of the highest priorities in people living with stroke. Post-stroke lower limb spasticity (PSLLS) impedes walking and quality of life (QOL). The understanding of the evidence of improved walking and QOL following botulinum toxin (BoNTA) injection is not clear. We performed a systematic review of the randomized control trials (RCT) to evaluate the effectiveness of BoNTA injection on walking and QOL in PSLLS. METHODS We searched PubMed, Web of Science, Embase, CINAHL, ProQuest Thesis and Dissertation checks, Google Scholar, WHO International Clinical Trial Registry Platform, ClinicalTrials.gov , Cochrane, and ANZ and EU Clinical Trials Register for RCTs looking at improvement in walking and QOL following injection of BoNTA in PSLLS. The original search was carried out prior to 16 September 2015. We conducted an additional verifying search on CINHAL, EMBASE, and MEDLINE (via PubMed) from 16 September 2015 to 6 June 2017 using the same clauses as the previous search. Methodological quality of the individual studies was critically appraised using Joanna Briggs Institute's instrument. Only placebo-controlled RCTs looking at improvement in walking and QOL were included in the review. RESULTS Of 2026 records, we found 107 full-text records. Amongst them, we found five RCTs qualifying our criteria. No new trials were found from the verifying search. Two independent reviewers assessed methodological validity prior to inclusion in the review using Joanna Briggs Institute's appraisal instrument. Two studies reported significant improvement in gait velocity (p = 0.020) and < 0.05, respectively. One study showed significant improvement in 2-min-walking distance (p < 0.05). QOL was recorded in one study without any significant improvement. Meta-analysis of reviewed studies could not be performed because of different methods of assessing walking ability, small sample size with large confidence interval and issues such as lack of power calculations in some studies. Findings from our systematic and detailed study identify the need for a well-designed RCT to adequately investigate the issues highlighted. CONCLUSIONS This review could not conclude there was sufficient evidence to support or refute improvement on walking or QOL following BoNTA injection. Reasons for this are discussed, and methods for future RCTs are developed.

Alignment options for total knee arthroplasty: A systematic review. Orthop Traumatol Surg Res 2017; 103:1047-1056.

Abstract
In spite of improvements in implant designs and surgical precision, functional outcomes of mechanically aligned total knee arthroplasty (MA TKA) have plateaued. This suggests probable technical intrinsic limitations that few alternate more anatomical recently promoted surgical techniques are trying to solve. This review aims at (1) classifying the different options to frontally align TKA implants, (2) at comparing their safety and efficacy with the one from MA TKAs, therefore answering the following questions: does alternative techniques to position TKA improve functional outcomes of TKA (question 1)? Is there any pathoanatomy not suitable for kinematic implantation of a TKA (question 2)? A systematic review of the existing literature utilizing PubMed and Google Scholar search engines was performed in February 2017. Only studies published in peer-reviewed journals over the last ten years in either English or French were reviewed. We identified 569 reports, of which 13 met our eligibility criteria. Four alternative techniques to position a TKA are challenging the traditional MA technique: anatomic (AA), adjusted mechanical (aMA), kinematic (KA), and restricted kinematic (rKA) alignment techniques. Regarding osteoarthritic patients with slight to mid constitutional knee frontal deformity, the KA technique enables a faster recovery and generally generates higher functional TKA outcomes than the MA technique. Kinematic alignment for TKA is a new attractive technique for TKA at early to mid-term, but need longer follow-up in order to assess its true value. It is probable that some forms of pathoanatomy might affect longer-term clinical outcomes of KA TKA and make the rKA technique or additional surgical corrections (realignment osteotomy, retinacular ligament reconstruction etc.) relevant for this sub-group of patients. Longer follow-up is needed to define the best indication of each alternative surgical technique for TKA. Level I for question 1 (systematic review of Level I studies), level 4 for question 2.

Abstract
Stem cells have demonstrated encouraging potential as reparative therapy for patients suffering from post-stroke disability. Reperfusion interventions in the acute phase of stroke have shown significant benefit but are limited by a narrow window of opportunity in which they are beneficial. Thereafter, rehabilitation is the only intervention available. The current review summarises the current evidence for use of stem cell therapies in stroke from early-phase clinical trials. The safety and feasibility of administering different types of stem cell therapies in stroke seem to be reasonably proven. However, the effectiveness needs still to be established through bigger clinical trials with more pragmatic clinical trial designs that address the challenges raised by the heterogeneous nature of stroke per se, as well those due to unique characteristics of stem cells as therapeutic agents.

Impact of Oncotype DX breast Recurrence Score testing on adjuvant chemotherapy use in early breast cancer: Real world experience in Greater Manchester, UK. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2017; 43:931-937.

Abstract
BACKGROUND The National Institute for Health and Clinical Excellence (NICE) recommended the Oncotype DX® Breast Recurrence Score® (RS) assay as an option for informing adjuvant chemotherapy decisions in node-negative, oestrogen receptor (ER)+, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer assessed to be at intermediate risk of recurrence based on clinicopathological factors. We evaluated the impact of RS testing on adjuvant chemotherapy decision-making in routine clinical practice in a UK Cancer Network. METHODS RS testing was performed in 201 females with newly diagnosed, ER+, HER2-negative, invasive breast cancer who underwent breast surgery with curative intent, were calculated to have a >3% overall survival benefit at 10 years from adjuvant chemotherapy based on PREDICT, and were considered for adjuvant chemotherapy. The impact of RS testing on adjuvant treatment decisions/associated cost was assessed. RESULTS In all patients, the multi-disciplinary team recommended chemotherapy but the RS result allowed 127/201 patients (63.2%) to avoid unnecessary adjuvant chemotherapy. Amongst ER+, HER2-negative, node-negative patients (eligible for Oncotype DX testing in UK guidelines), 60.3% were spared chemotherapy. In node-positive patients, the assay reduced the use of chemotherapy by 69.2%. The use of RS testing to guide treatment in these 201 patients was associated with significant cost saving (when considering the cost of RS testing for all patients plus chemotherapy and its associated cost for 74 patients). CONCLUSIONS Incorporating RS testing into routine clinical practice for selected node-negative and node-positive breast cancer patients significantly reduces the use of chemotherapy (p < 0.001) with its associated morbidity and costs.

Abstract
Tolstoy reports the existence of a characteristic 100 thousand year (ky) period in the bathymetry of fast-spreading seafloor but does not argue that sea level change is a first-order control on seafloor morphology worldwide. Upon evaluating the overlap between tectonic and Milankovitch periodicities across spreading rates, we reemphasize that fast-spreading ridges are the best potential recorders of a sea level signature in seafloor bathymetry.

Abstract
Huybers et al present new bathymetric spectra from an intermediate-spreading ridge as evidence for a primary contribution of sea level cycles to the morphology of the seafloor. Although we acknowledge the possibility that sea level-modulated magmatic constructions may be superimposed on a first-order tectonic fabric, we emphasize the difficulty of deciphering these different contributions in the frequency domain alone.

Abstract
Background and Aims: Postoperative pain for day surgery laparoscopic cholecystectomy has traditionally been managed with the surgeon infiltrating the wound with local anesthetic (LA). However, transversus abdominis plane (TAP) block has recently been used, although its superiority over LA remains uncertain. The primary aim was to compare LA and TAP block pain scores and analgesia used. The secondary aim was to assess satisfaction score and cost. Material and Methods: This retrospective study was commenced after ethics committee approval and ANZ clinical trial registry (ACTRN: 12612000737831). The data were collected from the theatre database and medical records of patients presenting for day case laparoscopic cholecystectomy. The sample included patients who received either bilateral port site LA infiltration with 20 ml of 0.25% Bupivacaine or bilateral TAP block with 20 ml of 0.5% ropivacaine and fentanyl postoperative pain protocol. The patients with incomplete medical records were excluded as were those admitted to an inpatient ward. Demographics and clinical characteristics were obtained from the hospital record along with pain score and postsurgery analgesia use. Postoperative pain satisfaction scores were collected by telephonic interview 30-180 days postsurgery. Results: Of 51 patients analyzed, 19 were in TAP group 29 in LA group. There were no significant differences between the LA and TAP groups with respect to postoperative pain scores (P = 0.31) or patient satisfaction scores (1 and 2+) (P = 0.36). However, fentanyl consumption in the recovery room was significantly lower in TAP group (P = 0.0079.). The consumables cost were >3 times higher in the TAP when compared to LA group. Conclusion: The performance of the TAP block with respect to pain management was comparable to LA. However, LA remains more cost effective.
