Abstract
INTRODUCTION Hiatus hernia is characterized by axial separation between the lower esophageal sphincter and the crural diaphragm, and higher reflux burden. Impact on reflux is unclear if such separation is intermittent rather than persistent. METHODS Reflux burden off antisecretory therapy was compared between no hernia (n = 357), intermittent hernia (n = 42), and persistent hernia (n = 155) after review of consecutive high-resolution manometry and reflux monitoring studies. RESULTS Proportions with pathologic acid exposure was similar between intermittent and persistent hernia (45.2% vs 46.5%, respectively), and both were significantly different from no hernia (28.7%, P ≤ 0.002). DISCUSSION Intermittent hiatus hernias are clinically relevant in gastroesophageal reflux pathophysiology.

Abstract
INTRODUCTION Diversity in the healthcare workforce is associated with improved performance and patient-reported outcomes. Gender disparity in Trauma and Orthopaedics (T&O) is well recognised. The aim of this study was to compare factors that influence career choice in T&O between male and female final-year students. Furthermore, the trend of representation of women in T&O over the last decade was also compared with other surgical specialities. METHODS An online survey of final-year students who attended nationally advertised T&O courses over a 2-year period was conducted. Data from NHS digital was obtained to assess gender diversity in T&O compared with other surgical specialities. RESULTS A total of 414 students from 13 UK medical schools completed the questionnaire. Compared with male students (34.2%), a significantly higher proportion of women (65.8%) decided against a career in T&O, p<0.001. Factors that dissuaded a significantly higher percentage of women included gender bias, technical aspects of surgery, unsociable hours, on-call commitments, inadequate undergraduate training and interest in another specialty (p<0.05). Motivating factors for choosing a career in T&O were similar between both sexes. T&O was the surgical specialty with the lowest proportion of women at both consultant and trainee level over the last decade. CONCLUSION T&O remains an unpopular career choice among women. To enhance recruitment of women in T&O, future strategies should be directed toward medical students. Universities, orthopaedic departments and societies must work collaboratively to embed culture change, improve the delivery of the undergraduate curriculum, and facilitate students' exposure to operating theatres and female role models.

Abstract
Background The Combination Antibiotic Therapy for Methicillin-Resistant Staphylococcus aureus (CAMERA2) trial ceased recruitment in July 2018, noting that a higher proportion of patients in the intervention arm (combination therapy) developed acute kidney injury (AKI) compared to the standard therapy (monotherapy) arm. We analyzed the long-term outcomes of participants in CAMERA2 to understand the impact of combination antibiotic therapy and AKI. Methods Trial sites obtained additional follow-up data. The primary outcome was all-cause mortality, censored at death or the date of last known follow-up. Secondary outcomes included kidney failure or a reduction in kidney function (a 40% reduction in estimated glomerular filtration rate to <60 mL/minute/1.73 m2). To determine independent predictors of mortality in this cohort, adjusted hazard ratios were calculated using a Cox proportional hazards regression model. Results This post hoc analysis included extended follow-up data for 260 patients. Overall, 123 of 260 (47%) of participants died, with a median population survival estimate of 3.4 years (235 deaths per 1000 person-years). Fifty-five patients died within 90 days after CAMERA2 trial randomization; another 68 deaths occurred after day 90. Using univariable Cox proportional hazards regression, mortality was not associated with either the assigned treatment arm in CAMERA2 (hazard ratio [HR], 0.84 [95% confidence interval [CI], .59-1.19]; P = .33) or experiencing an AKI (HR at 1 year, 1.04 [95% CI, .64-1.68]; P = .88). Conclusions In this cohort of patients hospitalized with methicillin-resistant S aureus bacteremia, we found no association between either treatment arm of the CAMERA2 trial or AKI (using CAMERA2 trial definition) and longer-term mortality.

Abstract
After introduction of faecal multiplex PCR that includes targets for stx1 and stx2 genes, we found stx genes were detected in 120 specimens from 111 patients over a 31-month period from 2018-2020 from a total of 14,179 separate tests performed. The proportion of stx1 only vs stx2 only vs stx1 and stx2 was 35%, 22% and 42%, respectively. There were 54 specimens which were culture positive, with 33 different serotypes identified, the predominant serotype being O157:H7 (19%). Eighty-two patients had clinical data available; we found a high rate of fever (35%), bloody diarrhoea (34%), acute kidney injury (27%), hospital admission (80%) and detection of faecal co-pathogens (23%). Only one patient developed haemolytic uraemic syndrome. We found no significant association with stx genotype and any particular symptom or complication. We found a significant association of serotypes O157:H7 and O26:H11 with bloody stool, but no significant association with any other symptom or complication.

Abstract
Coronavirus disease 2019 (COVID-19) infection in patients with haematological neoplasms has been associated with increased mortality; however, many studies in this patient group were reported early in the pandemic. The authors evaluated outcomes of COVID-19 infection in patients with haematological conditions following widespread vaccination, newer viral variants and increasingly effective antiviral therapies. A 4% mortality rate was found and contemporary risk factors for hospitalisation including older age, nonvaccination or partial COVID-19 vaccination status and infection with non-Omicron strain were identified.

Abstract
BACKGROUND Hiatus hernia (HH) contributes to development of gastroesophageal reflux disease, Barrett's esophagus and esophageal adenocarcinoma. This study was aimed to investigate the influence of HH on reflux patterns and distal esophageal mucosal integrity in non-erosive reflux disease (NERD). METHODS We retrospectively analyzed PPI-refractory NERD patients referred to three tertiary referral centers who underwent high-resolution manometry and off-PPI 24-h impedance-pH monitoring (with or without bile spectrophotometry). Patients with HH ≥2 cm (HH group, n = 42) or no HH (non-HH group, n = 40) with similar esophageal acid exposure time (AET 6%-12%) were included. KEY RESULTS Age, gender, BMI, esophageal motility, AET, and esophageal clearance were similar between the two groups. The HH group had higher numbers of total reflux episodes (p = 0.015) with similar proportion of acid/non-acid reflux compared with the non-HH group. Mean nocturnal baseline impedance (MNBI) in the distal esophagus was significantly lower in the HH group than the non-HH group at both 5 cm (p = 0.002) and 3 cm (p = 0.015) above the lower esophageal sphincter. Multivariable regression analysis showed that HH, less non-acid reflux and lower post-reflux swallow-induced peristaltic wave index (PSPWI) were independently associated with lower MNBI. Among 31 patients tested with bile spectrophotometry, the HH group had significantly longer bile exposure time than the non-HH group (p = 0.011), and bile reflux inversely and significantly correlated with MNBI (rho = -0.75, p < 0.001). CONCLUSIONS AND INFERENCES Hiatus hernia, less non-acid reflux and lower PSPWI were associated with lower MNBI. HH impairs distal esophageal mucosal integrity, the mechanism of which we speculate to be through excessive bile reflux.

Abstract
Background Acute-on-chronic liver failure (ACLF) represents a rising global healthcare burden, characterised by increasing prevalence among patients with decompensated cirrhosis who have a 28-day transplantation-free mortality of 33.9%. Due to disease complexity and a high prevalence of socio-economic disadvantage, there are deficits in quality of care and adherence to guideline-based treatment in this cohort. Compared to other chronic conditions such as heart failure, those with liver disease have reduced access to integrated ambulatory care services. The LivR Well programme is a multidisciplinary intervention aimed at improving 28-day mortality and reducing 30-day readmission through a home-based, liver optimisation programme implemented in the first 28 days after an admission with either ACLF or hepatic decompensation. Outcomes from our feasibility study suggest that the intervention is safe and acceptable to patients and carers. Methods We will recruit adult patients with chronic liver disease from the emergency departments, in-patient admissions, and an ambulatory liver clinic of a multi-site quaternary health service in Melbourne, Australia. A total of 120 patients meeting EF-Clif criteria will be recruited to the ACLF arm, and 320 patients to the hepatic decompensation arm. Participants in each cohort will be randomised to the intervention arm, a 28-day multidisciplinary programme or to standard ambulatory care in a 1:1 ratio. The intervention arm includes access to nursing, pharmacy, physiotherapy, dietetics, social work, and neuropsychiatry clinicians. For the ACLF cohort, the primary outcome is 28-day mortality. For the hepatic decompensation cohort, the primary outcome is 30-day re-admission. Secondary outcomes assess changes in liver disease severity and quality of life. An interim analysis will be performed at 50% recruitment to consider early cessation of the trial if the intervention is superior to the control, as suggested in our feasibility study. A cost-effectiveness analysis will be performed. Patients will be followed up for 12 weeks from randomisation. Three exploratory subgroup analyses will be conducted by (a) source of referral, (b) unplanned hospitalisation, and (c) concurrent COVID-19. The trial has been registered with the Australian New Zealand Clinical Trials Registry. Discussion This study implements a multidisciplinary intervention for ACLF patients with proven benefits in other chronic diseases with the addition of novel digital health tools to enable remote patient monitoring during the COVID-19 pandemic. Our feasibility study demonstrates safety and acceptability and suggests clinical improvement in a small sample size. An RCT is required to generate robust outcomes in this frail, high healthcare resource utilisation cohort with high readmission and mortality risk. Interventions such as LivR Well are urgently required but also need to be evaluated to ensure feasibility, replicability, and scalability across different healthcare systems. The implications of this trial include the generalisability of the programme for implementation across regional and urban centres.

Abstract
BACKGROUND Imperfect high-resolution manometry (HRM) studies can impact clinical management of patients with esophageal symptoms. METHODS Esophageal high-resolution manometry (HRM) studies attempted and/or performed by trained motility operators at a tertiary care center over a 2-year period were identified. When studies were attempted but not completed, reasons for an imperfect study (critically imperfect = LES not adequately traversed; non-critically imperfect = diaphragm not traversed), and point of identification (identified by motility nurse vs. identified on physician review) were recorded. Prevalence and clinical predictors of critically and non-critically imperfect studies were determined. KEY RESULTS Of 962 HRM studies attempted in 951 patients, 33 (3.4%) were critically imperfect (17 curled catheters), and 125 (13.0%) were non-critically imperfect. A third of critically imperfect studies, and 64.7% of curled catheters had achalasia, while 99.2% of non-critically imperfect studies had large hiatus hernias. Motility nurses detected 90.9% of critically imperfect and 55.8% of non-critically imperfect studies in real-time (p < 0.001). Achalasia independently predicted curled catheters; large hiatus hernias predicted non-critically imperfect studies (p < 0.001 for each). Compared to technically perfect studies, catheter curling was encountered more often in older patients, catheter intolerance in younger patients, and non-critically imperfect studies in females (p < 0.001 for each). No critical motor disorder was identified in intolerant patients. CONCLUSIONS AND INFERENCES Achalasia should be suspected when a curled catheter is encountered especially in older patients, while intolerant patients do not have critical motor disorders. Critically imperfect HRM studies are rare when performed by trained motility operators, which are identified in real time and aborted.

Abstract
INTRODUCTION Trauma and orthopaedics is renowned for being a challenging yet rewarding career. The value of mentorship in medical and surgical training is known to be beneficial; however, the prevalence and quality of mentorship opportunities in orthopaedics are less well studied. Identifying the strengths and weaknesses of mentoring programmes in orthopaedic training and recognising barriers to effective mentorship are key to unlocking the full potential of future orthopaedic surgeons. METHODS A comprehensive search of PubMed, Medline, EMBASE and the Cochrane Library was performed. All studies published in the English language that reported data on mentorship programmes in orthopaedic training were included. FINDINGS A total of 23 studies met the inclusion criteria. These studies demonstrated that formal mentorship programmes in orthopaedics are lacking but are sought after, with a positive influence on satisfaction and future career choice/subspecialty selection identified. Several barriers to mentoring in the field were recognised including the difficulty faced by female trainees, the availability of mentors and time constraints. The opportunity to choose a mentor, a mentor with the same interests, regular meetings and the option of gender congruent mentorship were all identified as crucial requirements for effective mentorship. CONCLUSION Mentorship opportunities must be more accessible to all orthopaedic trainees alike and should aim to incorporate the attributes identified to provide the highest calibre of training to prospective orthopaedic surgeons.

Abstract
BACKGROUND Limited surgeon-specific outcomes data are currently released to the public. Existing schemes generally result from the recommendations of public enquiries, addressing breaches to patient safety and malpractice. We found limited evidence in the literature about patients' or orthopaedic surgeons' wishes regarding the release of such data to the public. METHODS We surveyed 80 joint replacement patients and 41 orthopaedic surgeons regarding their wishes concerning collection and release of individual surgeon data to the public. RESULTS Of 80 patients, 30% (24/80) were aware of data on the NHS-My Choices website, 16% (13/80) had reviewed data prior to operation and 95% (76/80) wanted data concerning surgeons' experience, length of stay and complications including revisions. Patients expected more current monitoring of data than occurs. Of 41 surgeons, 20% (8/41) thought national joint registry (NJR) derived data accurately reflected their NHS work. Surgeons did not think this data improved patient outcomes (34%, 14/41), and that it reduced innovation (61%, 25/41) and training (75%, 31/41) and increased risk of adverse behaviour (61%, 25/41). Surgeons wanted a minimal data set accurately presented and risk adjusted. CONCLUSION In the future, it is likely that more individual surgeon data will be released to the public. There needs to be an agreed, accurate minimum dataset collected, reviewed in local clinical governance meetings and published with explanatory notes regarding the interfering variables and what conclusions can be drawn regarding the ability of the surgeon. This process needs to be overseen by an independent body trusted by the public.

Abstract
BACKGROUND Accurate reflux episode identification is crucial for pH-impedance interpretation. Individual reflux episode characteristics associated with inter-reviewer concordance are incompletely understood. METHODS Ambulatory pH-impedance studies from 19 GERD patients (median age 52 years, 78.9% F) were analyzed by 5 reviewers. Metadata from pH-impedance studies were exported to a dedicated software tool designed to compare episode-by-episode identification between reviewers within a ±7.5 s window. Patient position, acidic vs. nonacidic episodes, acid clearance time (ACT), bolus clearance time (BCT), and proximal extent of reflux episodes were compared between episodes identified by all reviewers against those identified by automated analysis, and one to four reviewers, respectively. RESULTS Automated analysis identified 1644 episodes (median 78 episodes per patient, IQR 64-108), of which 84.9% were identified by ≥3 reviewers and 57.1% by all reviewers; 339 unique episodes were added by at least 1 reviewer. Characteristics defining 5 reviewer concordance included acid reflux episodes (88.9%), upright episodes (88.4%), high proximal extent (median 17 cm, IQR 15-17 cm), and longer acid clearance times (67.0 s, IQR 29.0-146.0 s) (P < 0.001 compared to 1-4 reviewer concordance for each). In contrast, 1 reviewer-identified episodes were 69.8% acidic, 76.9% upright, and limited to the distal esophagus. Using 5-reviewer concordance, designation of GERD evidence changed from automated analysis in 16%-19% of patients. CONCLUSIONS Acidic episodes with high proximal extent in the upright position and longer acid clearance times on pH-impedance studies have the highest concordance for identification by expert reviewers. Reflux episode identification may be influenced by reviewer opinion despite availability of established criteria.

Abstract
BACKGROUND The COVID-19 pandemic has generated significant debate about how emerging infections can be treated in the absence of evidence-based therapies to combat disease. In particular, the use of off-label therapies outside of a clinical trial setting has been controversial. AIM We aimed to longitudinally study policies and prescribing practices pertaining to therapies for COVID-19 in Australian Health Services in 2020. METHODS Prospective data was collected from participating Australian health services who may care for patients with COVID-19 via an electronic portal. A single informant from each health service was emailed a survey link at regular intervals. Information was sought regarding changes to COVID-19 policy at their service and use of therapies for COVID-19. RESULTS Overall, 78 hospitals were represented from 39 respondents with longitudinal data collection from May to December 2020. All Australian states/territories were represented with the majority of respondents located in a major city (34/39; 87%). Just over half (20/39) of respondents had a written policy for COVID-19 therapy use at their health service at survey enrolment and policies changed frequently throughout the pandemic. Therapy use outside of a clinical trial was reported in 54% of health services, most frequently in Victoria, correlating with higher numbers of COVID-19 cases. At study commencement hydroxychloroquine was most frequently used, with corticosteroids and remdesivir use increasingly throughout the study period. CONCLUSION Our results reflect the reactive nature of prescribing of therapies for COVID-19 and highlight the importance of evidence-based guidelines to assist prescribers.

Abstract
Background/Aims The role of esophageal high-resolution manometry (HRM) within Lyon consensus phenotypes, especially patients with inconclusive gastroesophageal reflux disease (GERD) evidence, has not been fully investigated. In this multicenter, observational study we aim to compare HRM parameters in patients with GERD stratified according to the Lyon consensus. Methods Clinical and endoscopic data, HRM and multichannel intraluminal impedance-pH (MII-pH) studies performed off proton pump inhibitor therapy in patients with esophageal GERD symptoms were reviewed. Lyon consensus criteria identified pathological GERD, reflux hypersensitivity, functional heartburn, and inconclusive GERD. Patients, with inconclusive GERD were further subdivided into 2 groups based on total reflux numbers (≤ 80 or > 80 reflux episodes) during the MII-pH recording time. Results A total of 264 patients formed the study cohort. Pathological GERD and inconclusive GERD patients were associated with higher numbers of reflux episodes, lower mean nocturnal baseline impedance (MNBI) values, and a higher proportion of patients with pathologic MNBI compared to functional heartburn (P < 0.05 for each comparison). On multivariate analysis, pathological GERD and inconclusive GERD patients, both with ≤ 80 or > 80 reflux episodes, were significantly associated with pathologic esophagogastric junction contractile integral values and with presence of hiatus hernia (type 2/3 esophagogastric junction). Patients with inconclusive GERD and > 80 reflux episodes were significantly associated with fragmented peristalsis and ineffective esophageal motility whilst inconclusive GERD with ≤ 80 reflux episodes were significantly associated with fragmented peristalsis. Conclusion Esophageal motor parameters on HRM are similar between pathologic and inconclusive GERD according to the Lyon consensus.

Abstract
Abstract
Background
The Paterson report recommended increased release of individual surgeon data to the public. There is limited evidence in the literature about patients’ or orthopaedic surgeons’ wishes regarding release of such data to the public.
Method
We surveyed 80 joint replacement patients and 41 orthopaedic surgeons to determine their wishes regarding collection and release of individual surgeon data to the public.
Results
Patients expected more current monitoring of data than actually occurs. Of the patients, 95% wanted data to be available describing surgeon experience, length of stay and complications. Regarding currently available data, 50% of patients who were aware of it were likely to view it on the internet.
Surgeons were aware of the data available, but 80% did not think it was accurate. Surgeons did not think this data improved standards, that it negatively affected innovation (61%) and training (76%) and led to risk averse behaviour (61%). Surgeons wanted a minimal data set accurately presented and risk adjusted.
Conclusions
We recommend an agreed minimum dataset of good quality data is collected and discussed in clinical governance sessions. It can then be released to the public with explanatory notes.

Abstract
BACKGROUND & AIMS Reflux hypersensitivity (RH), a functional esophageal disorder, is detected in 14%-20% of patients who present with typical esophageal symptoms. As many as 40% of patients with RH do not respond to treatment with pain modulators or proton pump inhibitors (PPIs); behavior disorders might contribute to lack of treatment efficacy. We aimed to assess the prevalence of behavioral disorders and their effects on typical reflux symptoms in patients with RH. METHODS We performed a retrospective study of 542 patients with PPI-refractory esophageal symptoms (heartburn, regurgitation, or chest pain) or with symptoms that responded to PPI therapy, evaluated for anti-reflux surgery from January 2016 through August 2019 at a single center in London, United Kingdom. We collected data on symptoms, motility, and impedance-pH monitoring and assigned patients to categories of RH (n = 116), functional heartburn (n = 126), or non-erosive reflux disease (n = 300). RESULTS Of the 116 patients with a diagnosis of RH, 59 had only hypersensitivity, whereas 57 patients (49.2%) had either excessive supragastric belching (SGB, 39.7%), based on 24-hour impedance-pH monitoring, or rumination (9.5%), based on postprandial manometry combined with impedance. The prevalence of SGB and rumination in patients with RH was significantly higher than in patients with functional heartburn (22%; P < .001). Patients with RH and rumination were significantly younger (P = .005) and had the largest number of non-acid reflux episodes (P = .023). In patients with RH with SGB, SGB episodes were associated with 40.6% of marked reflux symptoms (heartburn, regurgitation, or chest pain), based on impedance-pH monitoring. In patients with RH and rumination, 40% of reflux-related symptoms (mostly regurgitation) were due to possible rumination episodes. CONCLUSIONS Almost half of patients with a diagnosis of RH have behavior disorders, including excessive SGB or rumination. Episodes of SGB or rumination are associated with typical reflux symptoms. Segregation of patients with diagnosis of RH into those with vs without behavioral disorders might have important therapeutic implications.

Abstract
INTRODUCTION The COVID-19 pandemic presented extraordinary challenges to the UK healthcare system. This study aimed to assess the impact of the COVID-19 lockdown on the epidemiology, treatment pathways and 30-day mortality rates of hip fractures. Outcomes of COVID-19 positive patients were compared against those who tested negative. METHODS An observational, retrospective, multicentre study was conducted across six hospitals in the South East of England. Data were retrieved from the National Hip Fracture Database and electronic medical records. Data was collected for the strictest UK lockdown period (period B=23 March 2020-11 May 2020), and the corresponding period in 2019 (period A). RESULTS A total of 386 patients were admitted during period A, whereas 381 were admitted during period B. Despite the suspension of the 'Best Practice Tariff' during period B, time to surgery, time to orthogeriatric assessment, and 30-day mortality were similar between period A and B. The length of inpatient stay was significantly shorter during period B (11.5 days vs 17.0 days, p<0.001). Comparison of COVID-19 positive and negative patients during period B demonstrated that a positive test was associated with a significantly higher rate of 30-day mortality (53.6% vs 6.7%), surgical delay >36h (46.4% vs 30.8%, p=0.049), and increased length of inpatient stay (15.8 vs 11.7 days, p=0.015). CONCLUSIONS The COVID-19 lockdown did not alter the epidemiology of hip fractures. A substantially higher mortality rate was observed among patients with a COVID-19 positive test. These findings should be taken into consideration by the healthcare policymakers while formulating contingency plans for a potential 'second wave'.

Abstract
AIMS To test the efficacy of a brief intervention to reduce alcohol or drug use and to promote use of addiction services among patients seeking mental health treatment. DESIGN AND SETTING A multi-centre, longitudinal, two-group randomized controlled trial with randomization within each of two mental health treatment systems located in Ventura County and Los Angeles County in California, USA. PARTICIPANTS A total of 718 patients (49.2% female) aged 18 and older with a mental health diagnosis and either a heavy drinking day or any use of cannabis or stimulants in the past 90 days. INTERVENTION AND COMPARATOR A motivation-based brief intervention with personalized feedback (screening, brief intervention and referral to treatment (SBIRT) condition) (n = 354) or a health education session (control condition) (n = 364). MEASUREMENTS Primary outcomes included frequency of heavy drinking days, days of cannabis use and days of stimulant use at the primary end-point 3 months post-baseline. Secondary outcomes included frequency and abstinence from substance use out to a 12-month follow-up and the use of addiction treatment services. FINDINGS Participants in the SBIRT condition had fewer heavy drinking days [odds ratio (OR) = 0.53; 95% credible interval (CrI) = 0.48-0.6] and fewer days of stimulant use (OR = 0.58; 95% CrI = 0.50-0.66) at the 3-month follow-up compared with participants in the health education condition. Participants in the SBIRT condition did not comparatively reduce days of cannabis use at the 3-month follow-up (OR = 0.93; 95% CrI = 0.85-1.01). Secondary outcomes indicated sustained effects of SBIRT on reducing the frequency of heavy drinking days and days of stimulant use. No effects were observed on abstinence rates or use of addiction treatment services. CONCLUSIONS Screening and brief intervention for unhealthy alcohol and drug use in mental health treatment settings were effective at reducing the frequency of heavy drinking and stimulant use.

Abstract
BACKGROUND Artificial intelligence (AI) has potential to streamline interpretation of pH-impedance studies. In this exploratory observational cohort study, we determined feasibility of automated AI extraction of baseline impedance (AIBI) and evaluated clinical value of novel AI metrics. METHODS pH-impedance data from a convenience sample of symptomatic patients studied off (n = 117, 53.1 ± 1.2 years, 66% F) and on (n = 93, 53.8 ± 1.3 years, 74% F) anti-secretory therapy and from asymptomatic volunteers (n = 115, 29.3 ± 0.8 years, 47% F) were uploaded into dedicated prototypical AI software designed to automatically extract AIBI. Acid exposure time (AET) and manually extracted mean nocturnal baseline impedance (MNBI) were compared to corresponding total, upright, and recumbent AIBI and upright:recumbent AIBI ratio. AI metrics were compared to AET and MNBI in predicting ≥ 50% symptom improvement in GERD patients. RESULTS Recumbent, but not upright AIBI, correlated with MNBI. Upright:recumbent AIBI ratio was higher when AET > 6% (median 1.18, IQR 1.0-1.5), compared to < 4% (0.95, IQR 0.84-1.1), 4-6% (0.89, IQR 0.72-0.98), and controls (0.93, IQR 0.80-1.09, p ≤ 0.04). While MNBI, total AIBI, and the AIBI ratio off PPI were significantly different between those with and without symptom improvement (p < 0.05 for each comparison), only AIBI ratio segregated management responders from other cohorts. On ROC analysis, off therapy AIBI ratio outperformed AET in predicting GERD symptom improvement when AET was > 6% (AUC 0.766 vs. 0.606) and 4-6% (AUC 0.563 vs. 0.516) and outperformed MNBI overall (AUC 0.661 vs. 0.313). CONCLUSIONS BI calculation can be automated using AI. Novel AI metrics show potential in predicting GERD treatment outcome.

Abstract
Background Cefiderocol, ceftazidime-avibactam, ceftolozane-tazobactam, intravenous fosfomycin and plazomicin represent potential carbapenem sparing agents for extended-spectrum-beta-lactamase or AmpC beta-lactamase producing Escherichia coli infection. However, available data is limited in predicting the volume of carbapenem therapy which could be substituted and real-world contraindications. Methods We determined the number of carbapenem days of therapy (DOT) which could be substituted and frequent contraindications accounting for antimicrobial susceptibility and site of infection in an unselected cohort with ceftriaxone-non-susceptible E. coli bacteremia at a single health network from 2015 to 2016. Individual patient data was used to calculate DOT and substitution for each agent. Results There were 108 episodes of E. coli bacteremia resulting in 67.2 carbapenem DOT/100 patient-days of antimicrobial therapy administered. Ceftazidime-avibactam could be used to substitute 36.2 DOT/100 patient-days (54%) for inpatient definitive therapy, ceftolozane-tazobactam for 34.7 DOT/100 patient-days (52%), cefiderocol for 27.1 DOT/100 patient-days (40%), fosfomycin for 23.3 DOT /100 patient-days (35%) and plazomicin for 27.1 DOT/100 patient-days (40%). Non-urinary tract source of infection was the most frequent contraindication to fosfomycin (25), plazomicin (26) and cefiderocol (26). Use in outpatient parenteral antimicrobial therapy (OPAT) programs accounted for 40% of DOT, all of which could be substituted if stability data allowed for ceftazidime-avibactam and ceftolozane-tazobactam. Conclusions All tested agents could be used to replace a significant volume of carbapenem therapy. Establishing stability of these agents for use in OPAT is required for maximizing their use as carbapenem sparing agents while randomized clinical data is awaited for some of these agents in resistant E. coli bacteremia.

Abstract
Background/Aims Impaired esophageal motility and disrupted esophagogastric junction (EGJ) on high-resolution manometry (HRM) have been associated with increased reflux severity in gastroesophageal reflux disease (GERD) patients. However, there are limited data evaluating HRM parameters in proton pump inhibitors (PPI) non-responders. Methods Clinical and endoscopic data, HRM and multichannel intraluminal impedance-pH studies performed of PPI therapy in patients with typical GERD symptoms were reviewed from 3 international centers. Frequency of GERD symptoms was assessed on and off PPI therapy in both non-responders (< 50% symptom improvement on PPI therapy) and responders. Rome IV definitions identified non-erosive reflux disease, reflux hypersensitivity, and functional heartburn. Univariate and multivariate analyses were performed to determine predictors of non-response. Results Of 204 patients, 105 were PPI non-responders and 99 were responders. Non-responders showed higher EGJ contractile integral values, and a lower frequency of type II and III EGJ morphology (P ≤ 0.03 for each comparison). Esophageal body diagnoses on HRM (fragmented peristalsis, ineffective esophageal motility, or absent peristalsis) did not predict non-response. On multivariate analysis, non-pathological acid exposure time (OR, 2.5; 95% CI, 1.2-5.0; P < 0.001), normal mean nocturnal baseline impedance values (OR, 2.7-2.4; 95% CI, 1.0-6.1; P < 0.05), normal EGJ contractile integral values (OR, 3; 95% CI, 1.3-7.4; P = 0.012), and presence of type I EGJ morphology (OR, 1.9; 95% CI, 1.0-3.4; P = 0.044) were associated with an unfavorable response to PPIs. Conclusions Intact EGJ metrics on HRM complement normal reflux burden in predicting non-response to PPI therapy. HRM has value in the evaluation of PPI non-responders.

Abstract
BACKGROUND Straight leg raise (SLR) while supine increases intra-abdominal pressure. We hypothesized that elevations in intra-abdominal pressure would transmit into the thoracic cavity if the esophagogastric junction (EGJ) was disrupted. METHODS Consecutive patients undergoing esophageal HRM were included if they had adequate SLR (hip flexion with knees extended for ≥ 5 seconds while supine). EGJ morphology was subtyped based on lower esophageal sphincter (LES) and crural diaphragm (CD) location (type 1: LES and CD overlap; type 2: separation of < 3 cm; type 3: separation of ≥ 3 cm). EGJ tone was assessed using EGJ contractile integral (EGJ-CI). HRM studies were analyzed according to Chicago Classification v3.0. Mean and peak intra-thoracic and abdominal pressures were measured at baseline and during SLR using on-screen software tools. Trans-EGJ gradients were compared, and pressure gradient < 1 mmHg denoted the equalization of pressures. KEY RESULTS Of 430 patients, 248 (57.5 ± 0.9 years, 69.4% F) completed SLR. EGJ morphology was type 1 in 122 (49.2%), type 2 in 56 (22.6%) and type 3 in 40 (16.1%). In types 1 and 2 EGJ, neither the mean nor peak trans-EGJ pressure gradient changed with SLR (P ≥ .17 for each). In contrast, in type 3 EGJ, peak pressure gradient decreased significantly following SLR (3.5 ± 1.8 mmHg vs. -8.6 ± 4.8 mmHg, P = .01). More type 3 EGJ patients equalized peak (65%) pressures across EGJ compared with types 1 and 2 (27%, P < .001). CONCLUSIONS AND INFERENCES The evaluation of intra-abdominal and intra-thoracic pressures with SLR during esophageal HRM can provide evidence of physiological disruption of the EGJ barrier.

Abstract
INTRODUCTION Bloodstream infections are a leading cause of mortality and morbidity; the duration of treatment for these infections is understudied. METHODS AND ANALYSIS We will conduct an international, multicentre randomised clinical trial of shorter (7 days) versus longer (14 days) antibiotic treatment among hospitalised patients with bloodstream infections. The trial will include 3626 patients across 60 hospitals and 6 countries. We will include patients with blood cultures confirming a pathogenic bacterium after hospital admission. Exclusion criteria will include patient factors (severe immunosuppression), infection site factors (endocarditis, osteomyelitis, undrained abscesses, infected prosthetic material) and pathogen factors (Staphylococcus aureus, Staphylococcus lugdunensis, Candida and contaminant organisms). We will leave the selection of specific antibiotics, doses and route of delivery to the discretion of treating physicians; no placebo control will be used given the diversity of pathogens and sources of bacteraemia. The intervention will be assignment of treatment duration to be 7 versus 14 days. We will minimise selection bias via central randomisation with variable block sizes, with concealed allocation until day 7 of adequate antibiotic treatment. The primary outcome is 90-day survival; we will test whether 7 days is non-inferior to 14 days of treatment, with a non-inferiority margin of 4% absolute mortality. Secondary outcomes include hospital and intensive care unit (ICU) mortality, relapse rates of bacteraemia, hospital and ICU length of stay, mechanical ventilation and vasopressor duration, antibiotic-free days, Clostridium difficile infection, antibiotic allergy and adverse events and colonisation/infection with antibiotic-resistant organisms. ETHICS AND DISSEMINATION The study has been approved by the ethics review board at each participating site. Sunnybrook Health Sciences Centre is the central ethics committee. We will disseminate study results via the Canadian Critical Care Trials Group and other collaborating networks to set the global paradigm for antibiotic treatment duration for non-staphylococcal Gram-positive, Gram-negative and anaerobic bacteraemia, among patients admitted to hospital. TRIAL REGISTRATION NUMBER The BALANCE (Bacteremia Antibiotic Length Actually Needed for Clinical Effectiveness) trial was registered at www.clinicaltrials.gov (registration number: NCT03005145).

Abstract
BACKGROUND Mean nocturnal baseline impedance (MNBI) augments the diagnostic yield of multichannel intraluminal impedance-pH (MII-pH) monitoring. While acid exposure time (AET) correlates with MNBI, it remains unclear whether esophageal motility affects MNBI values. The present study was aimed at evaluating the respective roles of esophageal motor function and AET on MNBI. METHODS High-resolution manometry (HRM) studies and ambulatory 24-hour MII-pH monitoring tracings were retrospectively analyzed from consecutive endoscopy-negative GERD patients with typical symptoms responsive to previous acid-suppressive therapy from three tertiary care centers. Univariate and multivariate analyses were performed to determine predictors of pathologic MNBI values at 3 cm and 5 cm above the lower esophageal sphincter (LES). KEY RESULTS Patients with pathological AET displayed lower MNBI values at 3 cm and 5 cm (P < .01) compared to patients with non-pathological AET. Similarly, significantly lower MNBI values were also noted at both sites with type 3 EGJ compared to type 1 EGJ (P ≤ .02 for each comparison), and with absent contractility compared to normal peristalsis (P ≤ .02 for each comparison). On multivariate analysis, the presence of type 2 or 3 EGJ and absent contractility were associated with a significantly higher probability of pathological MNBI values at 3 cm and 5 cm above the LES. CONCLUSIONS AND INFERENCES Disruption of the EGJ and absent contractility on HRM are both associated with lower MNBI values. HRM findings complement reflux testing using MII-pH monitoring.

Abstract
Objectives To characterize MDR Escherichia coli from bloodstream infections (BSIs) in Australia, New Zealand and Singapore. Methods We collected third-generation cephalosporin-resistant (3GC-R) E. coli from blood cultures in patients enrolled in a randomized controlled trial from February 2014 to August 2015. WGS was used to characterize antibiotic resistance genes, MLST, plasmids and phylogenetic relationships. Antibiotic susceptibility was determined using disc diffusion and Etest. Results A total of 70 3GC-R E. coli were included, of which the majority were ST131 (61.4%). BSI was most frequently from a urinary source (69.6%), community associated (62.9%) and in older patients (median age 71 years). The median Pitt score was 1 and ICU admission was infrequent (3.1%). ST131 possessed more acquired resistance genes than non-ST131 (P = 0.003). Clade C1/C2 ST131 predominated (30.2% and 53.5% of ST131, respectively) and these were all ciprofloxacin resistant. All clade A ST131 (n = 6) were community associated. The predominant ESBL types were blaCTX-M (80.0%) and were strongly associated with ST131 (95% carried blaCTX-M), with the majority blaCTX-M-15. Clade C1 was associated with blaCTX-M-14 and blaCTX-M-27, whereas blaCTX-M-15 predominated in clade C2. Plasmid-mediated AmpC genes (mainly blaCMY-2) were frequent (17.1%) but were more common in non-ST131 (P < 0.001) isolates from Singapore and Brisbane. Two strains carried both blaCMY-2 and blaCTX-M. The majority of plasmid replicon types were IncF. Conclusions In a prospective collection of 3GC-R E. coli causing BSI, community-associated Clade C1/C2 ST131 predominate in association with blaCTX-M ESBLs, although a significant proportion of non-ST131 strains carried blaCMY-2.

Abstract
Influenza A virus (IAV) is known to circulate among human and animal reservoirs, yet there are few studies that address the potential for urban rodents to carry and shed IAV. Rodents are often used as influenza models in the lab, but the few field studies that have looked for evidence of IAV in rodents have done so primarily in rural areas following outbreaks of IAV in poultry. This study sought to assess the prevalence of IAV recovered from wild Norway rats in a dense urban location (Boston). To do this, we sampled the oronasal cavity, paws, and lungs of Norway rats trapped by the City of Boston's Inspectional Services from December 2016 to September 2018. All samples were screened by real-time, reverse transcriptase PCR targeting the conserved IAV matrix segment. A total of 163 rats were trapped, 18 of which (11.04%) were RT-PCR positive for IAV in either oronasal swabs (9), paw swabs (9), both (2), or lung homogenates (2). A generalized linear model indicated that month and geographic location were correlated with IAV-positive PCR status of rats. A seasonal trend in IAV-PCR status was observed with the highest prevalence occurring in the winter months (December-January) followed by a decline over the course of the year, reaching its lowest prevalence in September. Sex and weight of rats were not significantly associated with IAV-PCR status, suggesting that rodent demography is not a primary driver of infection. This pilot study provides evidence of the need to further investigate the role that wild rats may play as reservoirs or mechanical vectors for IAV circulation in urban environments across seasons.

Abstract
Additional barriers to self-disclosure of HIV status exist for people living with HIV (PLH) with a history of drug use. The objectives of this study were to explore the extent of HIV disclosure, sexual practice patterns and the relationships between HIV disclosure and unprotected sex among Vietnamese male PLH with a history of drug use. We used cross-sectional data of a sample of 133 PLH collected from a randomized controlled intervention trial in Vietnam. More than one-quarter of the participants reported not disclosing their HIV status to any sexual partners. Self-reported rates of condom use were 67.8, 51.1 and 32.6% with regular, casual, and commercial partners, respectively. Unprotected sex, testing positive for heroin, and fewer years since HIV diagnosis were significantly associated with lower level of HIV disclosure. Future intervention programs should focus on the complex interplay among HIV disclosure, drug use, and unprotected sexual practices in this vulnerable population.

Abstract
INTRODUCTION Patients with microprolactinoma and idiopathic hyperprolactinaemia are not generally considered to be at risk of hypopituitarism and are therefore not routinely screened for this abnormality. In our clinical practice, we have observed a number of patients with nonmacroadenomatous hyperprolactinaemia to have anterior pituitary hormone deficits. AIMS We aimed to establish the frequency and clinical significance of anterior pituitary hormone deficiencies, comparing patients with radiologically proven microprolactinomas and patients with idiopathic hyperprolactinaemia. STUDY DESIGN We retrospectively examined the casenotes of 206 patients with hyperprolactinaemia from our centre. Patients who did not fit the profile of surgically naïve microprolactinoma or idiopathic hyperprolactinaemia or who had incomplete data were excluded, resulting in a study group of 56 patients. RESULTS A total of 35 patients with MRI evidence of microprolactinoma were identified, three (8.57%) of whom had one or more anterior pituitary hormone deficiencies. A total of 21 patients with MRI-negative idiopathic hyperprolactinaemia were identified, nine (42%) of whom had one or more anterior pituitary hormone deficiencies (P<.01). Only one patient in the MRI-positive group had deficiency that required hormone replacement, in contrast six patients in the MRI-negative group had deficiencies that were of clinical significance and which required hormone replacement. SUMMARY This study shows a clinically significant incidence of anterior pituitary hormone deficiency in patients with idiopathic hyperprolactinaemia. The authors recommend that dynamic pituitary assessment should be considered routinely in this patient group. A prospective study would be required to assess the underlying cause for these abnormalities, as they suggest a nontumour pan-pituitary process.

Abstract
Multidrug-resistant (MDR) gram-negative bacilli (GNB) are now globally widespread and present a major challenge to modern medical practice. Resistance to common antibiotics such as ceftriaxone is becoming more frequent in Australia, primarily mediated by extended-spectrum β-lactamase enzymes in common organisms such as Escherichia coli, and may occur in both hospital- and community-acquired infections. Carbapenem-resistant Enterobacteriaceae have emerged rapidly in recent years and are well established in many countries in the Asia-Pacific region. Although rare at present in Australia, they have caused significant nosocomial outbreaks. GNB have numerous mechanisms by which they can develop antibiotic resistance. Genes that encode extended-spectrum β-lactamases or carbapenemases are frequently co-located with multiple other resistance determinants on highly transmissible genetic structures such as plasmids. A key risk factor for infection with MDR GNB is travel to countries with high rates of resistance, especially with health care exposure. With limited prospects for new antibiotics in late-stage development that are active against MDR GNB, our national response to these challenges will require a multifaceted approach, including widespread implementation of antimicrobial stewardship, enhanced surveillance, targeted screening of at-risk patients and improved infection control practices. In the longer term, restriction of agricultural use of antibiotic classes critical to human medicine, removal of barriers to new drug development, and technological advances in rapid microbiological diagnostics will be required.
