Abstract
BACKGROUND Empty pelvis syndrome (EPS) is a significant source of morbidity following pelvic exenteration (PE), but is undefined. EPS outcome reporting and descriptors of radicality of PE are inconsistent; therefore, the best approaches for prevention are unknown. To facilitate future research into EPS, the aim of this study is to define a measurable core outcome set, core descriptor set and written definition for EPS. Consensus on strategies to mitigate EPS was also explored. METHOD Three-stage consensus methodology was used: longlisting with systematic review, healthcare professional event, patient engagement, and Delphi-piloting; shortlisting with two rounds of modified Delphi; and a confirmatory stage using a modified nominal group technique. This included a selection of measurement instruments, and iterative generation of a written EPS definition. RESULTS One hundred and three and 119 participants took part in the modified Delphi and consensus meetings, respectively. This encompassed international patient and healthcare professional representation with multidisciplinary input. Seventy statements were longlisted, seven core outcomes (bowel obstruction, enteroperineal fistula, chronic perineal sinus, infected pelvic collection, bowel obstruction, morbidity from reconstruction, re-intervention, and quality of life), and four core descriptors (magnitude of surgery, radiotherapy-induced damage, methods of reconstruction, and changes in volume of pelvic dead space) reached consensus-where applicable, measurement of these outcomes and descriptors was defined. A written definition for EPS was agreed. CONCLUSIONS EPS is an area of unmet research and clinical need. This study provides an agreed definition and core data set for EPS to facilitate further research.

The virulence of Dichelobacter nodosus, measured by the elastase test, is an important predictor for virulent footrot diagnosis in New South Wales sheep flocks. Aust Vet J 2023; 101:522-530. [PMID: 37794558 DOI: 10.1111/avj.13295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Revised: 09/11/2023] [Accepted: 09/25/2023] [Indexed: 10/06/2023]
Abstract
Ovine footrot is a contagious bacterial disease that causes foot lesions, and depending on the virulence of the causative strains, may lead to severe underrunning of the hoof and lameness. Virulent footrot can be identified, treated and controlled more effectively than less virulent benign forms. The in vitro elastase test for virulence of the causative bacteria, Dichelobacter nodosus, has been used to support clinical diagnosis. However, not all laboratory-designated virulent D. nodosus strains cause clinical signs of virulent footrot. This study evaluated retrospectively how well the elastase test supported clinical footrot diagnosis in 150 sheep flocks examined for suspect footrot in New South Wales between August 2020 and December 2021. Flocks were included if measures of clinical disease, environmental conditions and the virulence of D. nodosus isolates were available. Variation in the elastase activity result between D. nodosus isolated from the same flock made bacterial virulence hard to interpret, but calculating the mean elastase rate for all isolates from the same flock made correlations between bacterial virulence and flock footrot diagnosis possible. Simplifying bacterial virulence into whether there were any elastase-positive D. nodosus isolates before 12 days increased the predictive value of elastase results for virulent diagnosis, compared with using the first day that any isolate was elastase positive or the percentage of elastase-positive isolates by 12 days, but not all clinically virulent flocks had isolates with elastase activity before 12 days. Logistic regression models were fitted to identify the minimum number of predictors for virulent footrot diagnosis, with models suggesting that virulent footrot diagnosis was best predicted by adding the elastase test result and environmental conditions to the prevalence of severe foot lesions (score 4 and 5). However, performing the same analysis with different breeds, ages of sheep and seasons might highlight other factors important in the diagnosis of virulent footrot.

Abstract
Environmental exposures can have large impacts on health outcomes. While many resources have been dedicated to understanding how humans are influenced by the environment, few efforts have been made to study the role of built and natural environmental features on animal health. The Dog Aging Project (DAP) is a longitudinal community science study of aging in companion dogs. Using a combination of owner-reported surveys and secondary sources linked through geocoded coordinates, DAP has captured home, yard and neighbourhood variables for over 40,000 dogs. The DAP environmental data set spans four domains: the physical and built environment; chemical environment and exposures; diet and exercise; and social environment and interactions. By combining biometric data, measures of cognitive function and behaviour, and medical records, DAP is attempting to use a big-data approach to transform the understanding of how the surrounding world affects the health of companion dogs. In this paper, the authors describe the data infrastructure developed to integrate and analyse multi-level environmental data that can be used to improve the understanding of canine co-morbidity and aging.

Abstract
Abstract
Background
Older adults with acute fractures often have suboptimal pain control, in particular those with cognitive impairment. Effective pain management improves rehabilitation engagement and earlier discharge from acute care. Our study aimed to evaluate pain management of older adults with acute fracture admitted under an orthopaedic service in a tertiary hospital.
Methods
Prospective review of patients over 65 years with an acute fracture admitted under an orthopaedic service. Review of chart, medication prescription and pain status. Data included type of fracture, comorbidities, cognitive status and analgesia prescribed. Data analysed using Excel.
Results
40 inpatients included. Median age 82 years (range 65-93 years), 70% female. 53% had cognitive impairment, ranging from mild to severe dementia. 75% had >5 regular medications pre-admission. 80% had >5 comorbidities.
Two-thirds (73%) had an acute hip fracture. Most (80%) inpatients had a surgical intervention, the remaining were managed conservatively.
Analgesia prescriptions included paracetamol for almost all patients (95%), non-steroidal anti-inflammatory drugs for 3 (8%) and regular opioids in only 3 (8%).
43% of patients reported pain at time of data collection. 13% had analgesia changed in the 24 hours beforehand. Pain adversely affected function in 205 and mobility in 28%.
2 patients were unable to verbalise pain however no pain scales or visual assessments were used.
Documentation of pain assessment was best by nurses (100%) followed by doctors (60%) and allied health professionals (40%).
Conclusion
Older adults with acute fracture are often multimorbid with cognitive impairment. This patient population are often untreated for pain with suboptimal pain assessment and analgesia review or prescriptions. Consequently we developed a pain policy for use on our orthopaedic service as a guide for effective pain assessment and management for older adults with acute fracture.

Abstract
Abstract
Introduction
Hip fractures are a common presentation to Irish hospitals with 3,701 hip fractures recorded by 16 hospitals in the Irish Hip Fracture Database (IHFD) in 2019. Second hip fractures (HF2) make up a significant proportion of hip fractures and represent an opportunity to prevent subsequent fragility fracture.
Method
Hip fracture datasheets from 2019 in six Dublin hospitals were analysed.
Results
1,284 hip fractures in total were recorded in 2019 in these six hospitals. 112 of these were second hip fractures (8.72%). 24.1% of patients had a HF2 in year 1 post their first hip fracture (HF1). 14.3% of patients had a HF2 in Year 2, 8% in Year 3, 8.9% in Year 4 and 6.3% in Year 5. 17.9% of patients had an HF2 at an unknown time in relation to their HF1. 57.6% of all patients with any hip fracture were started on bone protection medications (BPMs) during their admission. 18.9% continued a pre-admission prescription. 7% of all patients were previously assessed and determined not to require BPM. 6.9% of patients were awaiting outpatient department (OPD) assessment for bone protection. 8.6% had no assessment for bone protection conducted. Of all patients with an HF2, 48.2% were started on BPMs on admission with their HF2. 33% continued BPMs started pre-admission.
Discussion
In 2019, approximately 1 in 10 hip fractures were second hip fractures. Evidence suggests that fracture liaison services represent a viable, economic means of preventing second hip fractures to improve patient outcomes and reduce healthcare expenditure.

Abstract
Abstract
Aim
More than 6000 children require specialist care from one of fourteen regional burns services in England and Wales each year. Families often have to travel long distances and may not have access to specialist care with restricted services due to Covid-19. This quality improvement project aimed to:
Method
We conducted a national service evaluation of children’s burns services in England and Wales. We then conducted a PRISMA compliant systematic review up to September 2020 to identify studies reporting chatbot use to deliver outpatient care. A chatbot was then developed using Dialogflow to identify complications and provide advice to families.
Results
Across England and Wales, 11 children’s burns services reported outpatient practice: six services follow up all children at three months, three have variable follow-up and two discharge all patients. Our systematic review identified 10 studies reporting chatbot use although none were used following burns. A frame-based system-focused chatbot was developed in conjunction with expert burns surgeons and patient representatives.
Conclusions
Chatbots are effective and acceptable alternatives for in-person follow up. We demonstrate national variation in the provision of outpatient paediatric burn care and have developed a chatbot that can address clinical concerns and provide reassurance to patients and family members. Future studies will determine the acceptability and safety of this chatbot.

Abstract
Abstract
Introduction
Major burns complicated by stress ulceration and perforation of the stomach or duodenum is a recognised clinical phenomenon. Colonic perforation in burns patients is seemingly uncommon, and the overall incidence, clinical signs/diagnosis of perforation, intervention required, and mortality is incompletely described in the literature.
Method
We performed a systematic review of the literature on severe burns resulting in colonic perforation during admission. Relevant studies from January 1975 to June 2020 were retrieved from MEDLINE and EMBASE databases. Patient demographics, total body surface area (TBSA), site of colonic perforation, management and overall outcome were extracted. We present a case series of five major burns patients who had colonic perforations in our Specialist Burns Centre.
Results
We identified 54 studies, of which nine (two case series and seven case reports) met the inclusion criteria. In most cases, the TBSA associated with a colonic perforation was ≥ 30% (10/16 patients, 63%) and the abdomen was involved in 9/16 patients (56%). Perforations mainly affected the right colon (12/16 patients, 75%), usually occurring after the second week of admission (13/16 patients, 81%). Right-sided colonic perforations were associated with an increased mortality rate compared to left-sided perforations (42% vs 25%).
Conclusions
The current literature, mainly limited to case series and case reports, confirms that colonic perforations in burns patients are rare. The resulting perforation is related to the systemic effect of burn injuries including sepsis and gastrointestinal stasis. We have identified patients who are at higher risk of developing colonic perforations in order to prompt early diagnosis and intervention.

Abstract
BACKGROUND Advances in natural language processing and other machine learning techniques have led to the development of automated agents (chatbots) that mimic human conversation. These systems have mainly been used in commercial settings, and within medicine, for symptom checking and psychotherapy. The aim of this systematic review was to determine the acceptability and implementation success of chatbots in the follow-up of patients who have undergone a physical healthcare intervention. METHODS A systematic review of MEDLINE, MEDLINE In-process, EMBASE, PsychINFO, CINAHL, CENTRAL and the grey literature using a PRISMA-compliant methodology up to September 2020 was conducted. Abstract screening and data extraction were performed in duplicate. Risk of bias and quality assessments were performed for each study. RESULTS The search identified 904 studies of which 10 met full inclusion criteria: three randomised control trials, one non-randomised clinical trial and six cohort studies. Chatbots were used for monitoring after the management of cancer, hypertension and asthma, orthopaedic intervention, ureteroscopy and intervention for varicose veins. All chatbots were deployed on mobile devices. A number of metrics were identified and ranged from a 31 per cent chatbot engagement rate to a 97 per cent response rate for system-generated questions. No study examined patient safety. CONCLUSION A range of chatbot builds and uses was identified. Further investigation of acceptability, efficacy and mechanistic evaluation in outpatient care pathways may lend support to implementation in routine clinical care.

Abstract
Abstract
Introduction
Clinical guidelines are associated with improved patient outcomes. This is especially true for junior staff members with little clinical experience. We created Pocket Guidelines for the management of surgical patients in ED, aimed at house officers.
Method
Seventeen common surgical conditions were selected for guidelines. Information was collated on presentation, exam findings, differential diagnosis, laboratory tests, imaging, indications for referral, and timing. Evidence based guidelines were approved by General Surgical consultants in the department. The utility of our guidelines was assessed by surveying 20 junior doctors.
Results
16 out of 20 house officers responded to the survey, ranging from post graduate year (PGY) 1 to 4, majority of them (37.5%) being PGY1. 69% were female and 31% were male.
A 5- point Likert scale was utilised for answers. No house officers ‘strongly agreed’ with being confident in managing surgical conditions in ED. Over 80% strongly agreed with the need to have ED clinical guidelines for surgical patients. Over 90% of house officers, having studied the pocket guidelines, found these useful.
Conclusions
We implemented pocket guidelines for general surgery in a rural hospital ED to streamline surgical admissions. Guidelines were found to be beneficial by the majority of junior doctors.

Abstract
BACKGROUND Polyglactin 910 is a synthetic braided, absorbable suture commonly used in surgery. Though polyglactin 910 suture-related pseudoinfection is well documented in the human literature, it has not been previously reported in the veterinary literature. CASE DESCRIPTION A 3-year-old female, ovariectomized but otherwise experimentally naïve Yucatan pig was evaluated for a several week history of bilateral multifocal abscesses in the area of the paralumbar fossa, which continued to worsen despite oral antibiotics and non-steroidal anti-inflammatory medications. The multi-focal abscesses continued to worsen and additional diagnostics were pursued including cytology, culture (aerobic, anaerobic and fungal), and bloodwork. All supported a non-infectious etiology. Biopsy results indicated a suture-related pseudoinfection. Despite treatment including parenteral antibiotics, pain medications and superficial surgical debridement, the dermatologic lesions worsened. Euthanasia was elected. Post-mortem necropsy demonstrated a suture-related pseudoinfection with extrusion of suture material from the ovarian pedicle ligatures through the body wall and skin leading to numerous sterile abscesses in the bilateral paralumbar fossa. CONCLUSIONS This is the first published report of a significantly delayed polyglactin 910 suture-related pseudoinfection in a Yucatan pig. While likely an isolated incident, it supports further research into this area. Additionally for critical research studies using Yucatan pigs, pre-surgical assessment with hypersensitivity patch testing may be appropriate.

Abstract
AIM At presentation, 15-20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection. METHOD Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival. RESULTS Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006). CONCLUSION Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.

Abstract
SETTING: The Philippines has a population of over 90 million people and is one of the 22 highest TB burden countries in the world.OBJECTIVE: To understand the economic cost of non-adherence to TB medicines due to loss to follow up and stock-outs in the Philippines.DESIGN: Data were collected on the economic costs of non-adherence to TB medicines and a model was developed to show those costs under different scenarios.RESULTS: The model showed that as many as 1958 and 233 persons are likely to have died as a result of DS-TB and MDR-TB loss to follow up, respectively, and 588 persons are likely to have died as a result of TB medicine stock outs. The related economic impact in each case is likely have been to be as much as US$72.2 million, US$13.4 million and US$21.0 million, respectively.CONCLUSION: The economic costs of non-adherence to TB medicines due to loss to follow-up and stock-outs represent a significant economic burden for the country and it is likely that the cost of addressing these problems would be much less than this burden and, therefore, a wise investment.

Abstract
INTRODUCTION The gastrointestinal microbiome has been suggested to contribute to the development of both primary and secondary colorectal cancer. Despite advances in understanding the prognostic and predictive value of clinico-pathological parameters, the underlying mechanisms that result in progression to metastatic disease have yet to be defined. The metastatic cascade involves a number of sequential steps, including detachment of tumour cells from the primary site, intravasation and dissemination within the circulatory and lymphatic systems, with extravasation and proliferation at a secondary site. OBJECTIVE An analysis of the literature relating to the gastrointestinal microbiome and its role in colorectal metastasis was conducted. This review aims to examine the current evidence supporting a role for the microbiome in colorectal metastasis and to describe the mechanisms by which it may contribute to metastatic progression. CONCLUSION The invasive pathways utilized by bacteria and how they may be manipulated by tumour cells for migration and metastasis are presented and the potential of the intestinal microbiome as a therapeutic target in colorectal carcinogenesis and metastasis is detailed here.

Canine Model for Selective and Superselective Cerebral Intra-Arterial Therapy Testing. Neurointervention 2020; 15:107-116.

Abstract
PURPOSE With advancing endovascular technology and increasing interest in minimally invasive intra-arterial therapies such as stem cell and chemotherapy for cerebral disease, the establishment of a translational model with cerebral circulation accessible to microcatheters is needed. We report our experience catheterizing canine cerebral circulation with microcatheters, present high-resolution angiographic images of the canine vascular anatomy, describe arterial branch flow patterns and provide measurements of canine arterial conduits. MATERIALS AND METHODS Angiograms were performed on 10 intact purpose-bred hounds. Angiography, measurements of arterial conduits and catheterization information for intracranial arterial branches were obtained. RESULTS Selective and superselective cerebral angiography was successful in all subjects. Relevant arterial mean diameters include the femoral (4.64 mm), aorta (9.38 mm), external carotid (3.65 mm), internal carotid arteries (1.6 mm), vertebrobasilar system and Circle of Willis branches. Catheterization of the Circle of Willis was achieved via the posterior circulation in all subjects tested (n=3) and the use of flow directed microcatheters resulted in reduced arterial tree deformation and improved superselection of intracranial vessels. Catheterization of the intracranial circulation was attempted but not achieved via the internal carotid artery (n=7) due to its tortuosity and subsequent catheter related vasospasm. CONCLUSION The canine cerebral vasculature is posterior circulation dominant. Anterior circulation angiography is achievable via the internal carotid artery, but direct cerebral arterial access is best achieved via the posterior circulation using flow-directed microcatheters. It is feasible to deliver intra-arterial therapies to selective vascular territories within the canine cerebral circulation, thus making it a viable animal model for testing novel intra-arterial cerebral treatments.

Critical care usage after major gastrointestinal and liver surgery: a prospective, multicentre observational study. Br J Anaesth 2019; 122:42-50.

Abstract
BACKGROUND Patient selection for critical care admission must balance patient safety with optimal resource allocation. This study aimed to determine the relationship between critical care admission, and postoperative mortality after abdominal surgery. METHODS This prespecified secondary analysis of a multicentre, prospective, observational study included consecutive patients enrolled in the DISCOVER study from UK and Republic of Ireland undergoing major gastrointestinal and liver surgery between October and December 2014. The primary outcome was 30-day mortality. Multivariate logistic regression was used to explore associations between critical care admission (planned and unplanned) and mortality, and inter-centre variation in critical care admission after emergency laparotomy. RESULTS Of 4529 patients included, 37.8% (n=1713) underwent planned critical care admissions from theatre. Some 3.1% (n=86/2816) admitted to ward-level care subsequently underwent unplanned critical care admission. Overall 30-day mortality was 2.9% (n=133/4519), and the risk-adjusted association between 30-day mortality and critical care admission was higher in unplanned [odds ratio (OR): 8.65, 95% confidence interval (CI): 3.51-19.97) than planned admissions (OR: 2.32, 95% CI: 1.43-3.85). Some 26.7% of patients (n=1210/4529) underwent emergency laparotomies. After adjustment, 49.3% (95% CI: 46.8-51.9%, P<0.001) were predicted to have planned critical care admissions, with 7% (n=10/145) of centres outside the 95% CI. CONCLUSIONS After risk adjustment, no 30-day survival benefit was identified for either planned or unplanned postoperative admissions to critical care within this cohort. This likely represents appropriate admission of the highest-risk patients. Planned admissions in selected, intermediate-risk patients may present a strategy to mitigate the risk of unplanned admission. Substantial inter-centre variation exists in planned critical care admissions after emergency laparotomies.

The magnitude of Yo-Yo test improvements following an aerobic training intervention are associated with total genotype score. PLoS One 2018; 13:e0207597.

Abstract
Recent research has demonstrated that there is considerable inter-individual variation in the response to aerobic training, and that this variation is partially mediated by genetic factors. As such, we aimed to investigate if a genetic based algorithm successfully predicted the magnitude of improvements following eight-weeks of aerobic training in youth soccer players. A genetic test was utilised to examine five single nucleotide polymorphisms (VEGF rs2010963, ADRB2 rs1042713 and rs1042714, CRP rs1205 & PPARGC1A rs8192678), whose occurrence is believed to impact aerobic training adaptations. 42 male soccer players (17.0 ± 1y, 176 ± 6 cm, 69 ± 9 kg) were tested and stratified into three different Total Genotype Score groups; "low", "medium"and "high", based on the possession of favourable polymorphisms. Subjects underwent two Yo-Yo tests separated by eight-weeks of sports-specific aerobic training. Overall, there were no significant differences between the genotype groups in pre-training Yo-Yo performance, but evident between-group response differentials emerged in post-training Yo-Yo test performance. Subjects in the "high" group saw much larger improvements (58%) than those in the 'medium" (35%) and "low" (7%) groups. There were significant (p<0.05) differences between the groups in the magnitude of improvement, with athletes in the "high" and medium group having larger improvements than the "low" group (d = 2.59 "high" vs "low"; d = 1.32 "medium" vs "low"). In conclusion, the magnitude of improvements in aerobic fitness following a training intervention were associated with a genetic algorithm comprised of five single nucleotide polymorphisms. This information could lead to the development of more individualised aerobic training designs, targeting optimal fitness adaptations.

Abstract
AIMS Advanced biliary tract carcinomas (ABC) are malignancies with limited effective therapies for advanced disease. There is little published evidence of outcomes of ABC patients participating in phase I clinical trials. MATERIALS AND METHODS Patient characteristics, treatment details and outcomes of ABC patients treated at a dedicated phase I unit were captured and analysed from case and trial records. RESULTS In total, 123 ABC patients were included in the study, of which 48 patients participated in 41 different phase I trials; 75 (61%) did not participate due to rapid disease progression or patient choice. Molecular characterisation of tumours using a targeted panel was conducted in 15 (31%), yielding several potentially actionable mutations, including BRCA, PIK3CA, FGFR, AKT and PTEN loss. Of the 39 evaluable patients there was one exceptional responder. Eighteen (46%) other patients achieved stable disease as their best response, with a clinical benefit rate at 4 months of 10%. Treatment was generally well tolerated with grade 3 or 4 adverse events only observed in eight patients (17 %), of which six were drug related and led to trial discontinuation in one (3%), with no toxicity-related deaths. CONCLUSION Carefully selected ABC patients have been found to tolerate experimental phase I clinical trials without excess toxicity. The aggressive nature of this disease warrants consideration of early referral to a phase I unit. Future work will require comprehensive molecular profiling in an attempt to understand the biology underlying the exceptional responders and to match patients in real-time to targeted therapies.
