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.

Abstract
Background Opportunistic pathogens have been postulated to drive dysregulated inflammation in inflammatory bowel disease (IBD). Indeed, adherent-invasive Escherichia coli (AIEC) isolated from IBD patients have pathobiont and pro-inflammatory characteristics. Current treatments for IBD suppress the immune response and do not target key microbial drivers, therefore novel strategies are required. Purpose Our aim was to determine whether bacteriophage therapy targeted against AIEC could reduce the severity of E. coli-driven colitis in gnotobiotic mice. Method Adult germ-free C57BL/6 mice were colonized with altered Schaedler-like flora (ASF) and E. coli NRG857c, a Crohn’s disease-associated bacterial isolate. Three weeks later, mice were treated with daily phage (selected by killing curves bioassays against E. coli NRG857c) or PBS for 2 weeks (n=6/group). Mice were then exposed to low-dose dextran sulfate sodium (2%; DSS) in drinking water for 5 days, followed by 2 days of water. PBS-treated mice (n=6) that received no DSS were used as additional negative controls. Mice were monitored daily for weight, stool consistency, and occult blood. At sacrifice, colon tissue was collected for histological analysis and fecal contents were cultured to determine bacterial load. In separate experiments, C57BL/6NTac-Il10em8Tac (IL-10-/-) mice were colonized with ASF-like microbiota and E. coli NRG857c. Three weeks later, mice (n=5) were treated with weekly phage or PBS (n=5) for 7 weeks. Mice were monitored weekly as described above. Result(s) Daily phage treatment reduced the severity of clinical symptoms induced by acute DSS administration (p < 0.001 vs. DSS-PBS treated mice). At endpoint, phage treatment was associated with lower histological scores as compared with DSS-PBS controls (p < 0.0001). A 1-log reduction in AIEC bacterial load was observed in phage treated mice as compared with DSS-PBS controls (p < 0.001). In IL-10-/- mice, weekly phage treatment delayed the spontaneous onset of colitis (p < 0.0001 vs. PBS-treated mice). At endpoint, mice treated with phage had lower colitis scores. Reduced weekly AIEC bacterial load was observed in phage-treated mice. Conclusion(s) Lytic phages, targeting a known AIEC pathobiont isolated from Crohn’s disease patients, ameliorate acute intestinal injury and delay onset of spontaneous colitis. Future work will investigate the mechanisms by which phage therapy prevents and treats colitis, to better inform clinical trial design. Disclosure of Interest None Declared

Abstract
Background An imbalance in host proteases has been implicated in inflammatory bowel disease (IBD). Recent evidence implicates microbial proteolytic activity (PA) in ulcerative colitis but whether it also plays a role in Crohn’s disease (CD) remains unclear. Purpose We therefore investigated the colitogenic potential and underlying pathways of proteolytic CD microbiota. Method Adult germ-free (GF) C57BL/6 mice were colonized with CD microbiota selected based on high (CD-HPA) or low fecal proteolytic activity (CD-LPA), and from healthy controls with LPA (HC-LPA), after which total fecal proteolytic, elastolytic and mucolytic activity were analyzed in the mice. Microbial community was assessed by 16S rRNA gene sequencing. Immune function and colonic injury were investigated by inflammatory gene expression (NanoString) and histology. Colitis severity and underlying pathways were investigated in C57BL/6, Nucleotide-binding Oligomerization Domain-2 knock-out (Nod2-/-), and Protease-Activated Receptor 2 (PAR2) cleavage resistant mice (R38E-PAR2) subjected to 2% dextran sodium sulfate in drinking water for 5 days followed by 2 days on water. Result(s) Colonization with HC-LPA or CD-LPA lowered baseline fecal proteolytic activity compared with GF mice, which was paralleled by lower acute inflammatory cell infiltrate. CD-HPA further increased proteolytic activity compared with GF mice. Fecal supernatants from CD-LPA or HC-LPA colonized mice had lower in vitro PAR2 cleavage compared to supernatants from GF and CD-HPA colonized mice. Several genes, such as Map kinases, Rhoa, Myd88, and Tollip, were increased in GF mice compared to colonized mice. 18 genes related to inflammation and barrier function (e.g., Mapk2k6, Tnf, Claudin1) were differentially expressed between CD-LPA and CD-HPA. CD-HPA mice had lower alpha diversity, distinct microbial profiles, and higher fecal proteolytic activity compared with CD-LPA. Abundance of several beneficial species (e.g., Akkermansia muciniphilia) was decreased while other taxa were increased (e.g., Hungattella hathewayi) in CD-HPA compared to CD-LPA. H. hathewayi as well as the serine protease K04772 were transcriptionally increased in fecal samples from CD-HPA colonized mice. C57BL/6 and Nod2-/- mice, but not R38E-PAR2 mice, colonized with CD-HPA developed earlier and more severe colitis compared with mice colonized with CD-LPA. Conclusion(s) CD proteolytic microbiota is proinflammatory through a PAR2 pathway. H. hathewayi correlates with the proinflammatory phenotype through the serine protease K04772 in this model. The results support a role of microbial PA in CD, which could constitute a biomarker for identifying patients who would benefit from anti-proteolytic therapies. Disclosure of Interest None Declared

Abstract
Positive psychological interventions (PPIs), programs that specifically target positive emotions, cognitions, and behaviors, have been shown to reduce depression and improve other aspects of psychological well-being. However, potential pathways linking PPIs to better outcomes have been under-explored. In this paper, we report the results of a randomized trial of a self-guided online delivered PPI called MARIGOLD (Mobile Affect Regulation Intervention with the Goal of Lowering Depression). Participants with elevated depression were randomized to receive MARIGOLD (n = 539) or an emotion reporting control condition (n = 63). In addition to testing direct effects of the intervention on depressive symptoms, we explored whether positive or negative emotion-operationalized as past day, past week, reactivity, or flexibility-mediated the intervention impact on depression. Results demonstrated that participants in the MARIGOLD condition had reduced depressive symptoms compared to controls and, although the effect did not reach statistical significance, reductions in past day negative emotion appeared to mediate this effect. Contrary to hypotheses, the intervention did not increase positive emotion compared to the control condition. Discussion focuses on the need for future studies to continue investigating the mechanisms of action for PPIs with emphasis on theoretically-based measurement and operationalization of emotion and other potential mediators to maximize the ultimate impact of PPIs on psychological well-being.

Abstract
INTRODUCTION Burn injury remains a serious cause of morbidity and mortality worldwide. Severity of burns is determined by the percentage of burned area compared to the body surface area, age of patient, and by the depth of skin and soft tissue involvement; these factors determine management as well as prospective outcomes. The pathophysiology of partial- to full-thickness burn conversion remains poorly understood and is associated with a worse overall prognosis. Recent studies have demonstrated that an altered inflammatory response may play a significant role in this conversion and therefore a reduction in early inflammation is crucial to ultimately decreasing burn severity and morbidity. We hypothesize that the application of a microcapillary gelatin-alginate hydrogel loaded with anti-TNF-α (infliximab) monoclonal antibodies to a partial-thickness burn will reduce inflammation within partially burned skin and prevent further progression to a full-thickness burn. METHODS Assembly of the microfluidic hydrogels is achieved by embedding microfibers within a hydrogel scaffold composed of a gelatin-alginate blend, which is then soaked in a solution containing anti-TNF-α antibodies for drug loading. 12 young (2-4 months) and 12 old (>16 months) mice were given partial thickness burns. The treatment cohort received the anti-TNF-α infused hydrogel with an occlusive dressing and the control cohort only received an occlusive dressing. Mice were euthanized at post-burn day 3 and skin samples were taken. Burn depth was evaluated using Vimentin immunostaining. RESULTS All mice in the treatment cohort demonstrated decreased conversion of burn from partial to full thickness injury (old = p < 0.01, young = p < 0.001) as compared to the control group. Old mice had greater depth of burn than young mice (p < 0.001). There were greater eosinophils in the treatment cohort for both young and old mice, but it did not reach statistical significance. CONCLUSION The application of a novel microcapillary gelatin-alginate hydrogel infused with anti-TNF-α antibody to partial thickness burns in mice showed reduction in partial to full thickness burn secondary progression as compared to controls using this murine model; this promising finding might help decrease the high morbidity and mortality associated with burn injuries.

Abstract
Introduction The pathophysiology of partial- to full-thickness burn wound conversion remains poorly understood. Recent studies have demonstrated that an altered inflammatory response may play be implicated in this secondary conversion to deeper wounds. Therefore, reduction in early inflammation may decrease burn severity and morbidity. Specifically, TNF-ɑ has been shown to detrimentally affect the healing process after injury through a variety of mechanisms. We hypothesized that microcapillary alginate hydrogel loaded with immunosuppressive medications applied to partial-thickness burns would reduce inflammation and prevent further progression to full-thickness burns. The purpose of this study was to determine whether topical application of infliximab or tacrolimus could decrease burn wound depth. Methods Assembly of the microfluidic hydrogels was achieved by embedding microfibers within a hydrogel scaffold composed of an alginate blend. The treatment cohorts received either (1) infliximab loaded hydrogel or (2) tacrolimus skin ointment covered by hydrogel. The control cohort only received an occlusive dressing. There were 12 young (2-4 months) and 12 old ( >16 months) mice, which were separated into treatment and control cohorts. All mice were anesthetized and given partial thickness burns by a validated scalding protocol. Mice were euthanized on post-burn day 3, and skin samples were taken. Burn depth was evaluated using Vimentin immunostaining. Results In young mice, infliximab hydrogel (p=.002) and tacrolimus hydrogel (p=.002) significantly decreased burn depth compared to controls. In old mice, infliximab hydrogel (p=.005) and tacrolimus hydrogel (p< .001) significantly decreased burn depth compared to controls. In young mice, infliximab and tacrolimus were similarly efficacious (p > .05). In old mice, tacrolimus significantly decreased burn depth compared to infliximab (p=.002). In controls, old mice had deeper burn wound progression than young mice (p< .001). Similarly, in those treated with infliximab, old mice had deeper burn wound progression than young mice (p=.002). Interestingly, tacrolimus was able to decrease burn wound depth in old mice such that their burn wound thickness was similar to young mice (p >.05). Conclusions Application of a novel microcapillary alginate hydrogel infused with infliximab or topical tacrolimus reduced partial- to full-thickness burn wound conversion in mice. Application of immunosuppressive dressings may be a promising avenue for further clinical investigation to reduce morbidity and mortality associated with burn injuries.

Abstract
Abstract
Background
Bacterial infections have been postulated to drive the dysregulated inflammation found in inflammatory bowel disease (IBD). In particular, adherent-invasive Escherichia coli (AIEC) isolated from patients with IBD have pathobiont characteristics and have been implicated in IBD pathogenesis.
Aims
Our aim was to characterize and compare the level of intestinal inflammation and potential microbiota shifts induced by E. coli clinical isolates using a gnotobiotic mouse model of colitis.
Methods
Adult germ-free C57BL/6 mice were transferred to ISO positive cages in a gnotobiotic facility and colonized with altered Schaedler flora-like (ASF) microbiota and one of three clinical E. coli isolates: E. coli C0004 (n = 5), E. coli LF82 (n = 9), E. coli NRG857c (n = 6), or ASF alone (n = 6). Three weeks later, mice were treated for 5 days with low dose dextran sodium sulphate in drinking water (2%; DSS), followed by 2 days of water. Mice were monitored daily for clinical symptoms (weight, stool consistency, and occult blood). At sacrifice, colon tissue was collected for histological analysis. Cecum contents were cultured to determine bacterial load. Fecal samples were collected for 16S rRNA gene sequencing analysis before and after DSS treatment.
Results
All mice colonized with an E. coli isolate displayed significantly greater clinical and microscopic scores of colitis compared to ASF alone, but the severity was dependent on the colonized E. coli strain. E. coli NRG857c-colonized mice exhibited more severe symptoms (p < 0.001) two days earlier than mice colonized with other E. coli isolates. Mice colonized with E. coli LF82 or E. coli NRG857c had higher histological scores of colitis compared to mice colonized with E. coli C0004, which were also significantly greater than ASF alone (p < 0.0001). 16S rRNA gene sequencing revealed that ASF-alone-colonized mice lacked Proteobacteria. All E. coli-colonized mice had comparable bacterial loads, which were verified by 16S rRNA analysis. Following DSS, E. coli LF82 and E. coli NRG857c relative abundance remained stable, whereas the relative abundance of Roseburia/ASF 492 declined significantly in all E. coli colonized mice.
Conclusions
The presence of E. coli pathobionts in mice drive the severity of chemically induced colitis, with AIEC NRG857c inducing the greatest severity. This gnotobiotic mouse model enables us to control the severity of colitis in a well-defined microbiota that is dependent on the colonized E. coli isolate. Using this model, we will be able to assess therapeutic candidates that aim to treat colitis at varying stages of its disease progression.

Abstract
Background Ulcerative colitis (UC) is one of two forms of inflammatory bowel disease (IBD). The exact cause of IBD is unknown but altered host-microbe interactions and genetic susceptibility are involved in its pathogenesis. Many patients with IBD do not respond to biological therapies targeting single cytokines, therefore new therapies that target common immune pathways are being developed and need to be tested in relevant preclinical models. Previously we have shown that mice colonized with UC microbiota upregulated genes related to inflammation without induction of colitis compared to healthy volunteer-colonized mice. We thus investigated whether IRAK4 and TPL2-induced pathways, new therapeutic targets in development upstream of inflammatory cytokine gene activation, are upregulated in mice colonized with UC microbiota and chronic colitis. Aims Our aim was to characterize TPL2 and IRAK4 signalling pathways and T cell phenotypes in UC-colonized mice following chronic low-dose dextran sodium sulfate (DSS) colitis. Methods 10-16-week-old germ-free C57BL/6 mice were colonized with fecal microbiota from a patient with UC experiencing a flare (n=16). Mice were housed in a gnotobiotic facility during the experiment. Three weeks following colonization, colitis was induced in half of the mice by three cycles (5 d each; 2.0%, 1.5% and 1.5%, respectively) of DSS in drinking water with a 5-d wash-out period between cycles. All mice were fed a control diet (7004, Teklad). Fecal samples were collected weekly. At sacrifice, disease activity (colon length, occult blood in feces, stool consistency, and spleen weight) was measured and colon tissue was collected for histological analysis and RNA sequencing. Mesenteric lymph nodes (MLNs) were acquired for flow cytometry to analyze T cell phenotypes. Results In UC-colonized mice, chronic low-dose DSS induced softer feces (p<0.0001), shorter colon length (p<0.0001), and increased spleen weight (p<0.0001), compared with water treated mice. This was paralleled by detectable blood in stool, development of moderate colitis (DSS: 1.9+/-1.4 vs H2O: 0.5+/-0.2; p<0.02) and higher proportion of IL-17 (p=0.003) and IFN-γ-producing T cells (p=0.06) in MLNs compared with water treated mice. RNA sequencing revealed that inflammatory genes, mainly related to the IRAK4/TPL2 pathway (e.g., Gadd45b, Socs3, Il1b), were significantly increased (p≤0.05) in the colon of mice treated with DSS compared with water. Conclusions When challenged with a chronic low-dose chemical injury agent, mice colonized with UC microbiota develop clinical and histological signs of colitis and upregulation of genes involved in inflammation like Gadd45b, Socs3, and Il1b. Thus, this model represents a new valuable tool for preclinical testing of new drug candidates, such as those related to the modulation of IRAK4/TPL2 pathways. Funding Agencies CCC

Abstract
OBJECTIVE Malignant Pleural Effusion (MPE) carries significant morbidity and mortality. Indwelling pleural catheters (IPCs) are established in the management pathway. Large case reviews add to the evidence base regarding safety and efficacy. PATIENTS AND METHODS 168 patients had an IPC inserted between January 2012 and December 2018 in a large pleural centre. Data on outcomes and complications were obtained from the patients' notes, laboratory and radiographic findings. A descriptive statistical methodology was applied. RESULTS 168 IPCs were inserted in a predominantly male population. The overall complication rate is 13%. The incidence of any individual complication such as infection, metastatic seeding, drain displacement, and loculations are all less than previously described. CONCLUSIONS This case review adds to the large body of evidence that IPCs are safe and have minimal complications. Specific factors enabling this are the use of pre-operative antibiotics, the use of theatre space, and the experience of the pleural interventional physicians.

Abstract
INTRODUCTION Although orbital fractures are less common in children than adults, the literature suggests that orbital entrapment occurs more frequently in the pediatric population. Orbital entrapment is an emergency, and early diagnosis and prompt management are critical. Specific radiographic manifestations such as herniation of extraocular muscles (EOMs) through orbital fractures have led to increased suspicion and overdiagnosis of orbital entrapment. This study evaluated the value of specific radiographic findings in predicting clinical findings after pediatric orbital floor fractures. METHODS A retrospective review at a pediatric level 1 trauma center was performed. ICD-9 and ICD-10, codes identified patients with orbital fractures. Computed tomography (CT) reports were queried for the following terms: "herniation," "herniated," "entrapped," and "entrapment." Patients 16 years and older were excluded, as were all patients who were unable to undergo EOM evaluation on presentation. Electronic medical records were reviewed for fracture type, mechanism of injury, clinical and radiographic findings, surgical interventions, and demographic information. Medical diagnosis tests, including positive and negative predictive values, sensitivity, as well as specificity, were calculated to identify the relationship between radiographic findings and specific symptomology. RESULTS One hundred fifty-three patients with 265 orbital fractures were included. "Entrapment" was mentioned in 34.6% of CT reports, whereas the incidence of clinical entrapment was 12.4% (19/153). Radiographic fat herniation, EOM herniation, and EOM irregularity had positive predictive values of 25%, 31%, and 10%, respectively, for clinical entrapment diagnosis at the initial examination. Overall, 32.7% (50/153) of patients with orbital fractures required surgery. CONCLUSIONS Although the radiographic description of soft tissue herniation has become interchangeable with entrapment, these CT findings alone are poorly predictive. Orbital entrapment should be diagnosed preoperatively by physical examination, with radiographs as an adjunct only. Radiographic statements without clinical correlation may lead to the improper management of pediatric facial trauma patients.

Abstract
Fluorescence-activated cell sorting (FACS) is a branch of flow cytometry that allows for the isolation of specific cell populations that can then be further analyzed by single-cell RNA sequencing (scRNA-seq). When utilizing FACS for population isolation prior to sequencing, it is essential to consider the protection of RNA from RNase activity, environmental conditions, and the sorting efficiency to ensure optimum sample quality. This study aimed to optimize a previously published MDSC flow cytometry strategy to FACS sort canine Myeloid-Derived Suppressor Cells (MDSC) with various permutations of RNAlater ™ and RiboLock™ before and after FACS sorting. Concentrations of RNAlater™ greater than 2 % applied before flow analysis affected cell survival and fluorescence, whereas concentrations ≤ 2 % and time ≤ 4 h had little to no effect on cells. To shorten the procedural time and to enhance the sorting of rare populations, we used a primary PE-conjugated CD11b antibody and magnetic column. The combination of RiboLock™ pre- and post-sorting for FACS provided the best quality RNA as determined by the RNA integrity number (RIN ≥ 7) for scRNA-seq in a normal and dog and a dog with untreated oral melanoma dog. As proof of principle, we sequenced two samples, one from a normal dog another from a dog with untreated oral melanoma. Applying scRNA-Seq analysis using the 10X Genomic platform, we identified 6 clusters in the Seurat paired analysis of MDSC sorted samples. Two clusters, with the majority of the cells coming from the melanoma sample, had genes that were upregulated (> log2); these included MMP9, MMP1, HPGD, CPA3, and GATA3 and CYBB, CSTB, COX2, ATP6, and COX 17 for cluster 5 and 6 respectively. All genes have known associations with MDSCs. Further characterization using pathway analysis tools was not attempted due to the lower number of cells sequenced in the normal sample. The benefit deriving from the results of the study helped to gain data consistency when working with cells prone to RNase activity, and the scRNA-seq provided data showing transcriptional heterogeneity in MDSC populations and potentially identifying previously unreported or rare cell populations.

Abstract
Background: Active cigarette smoking (CS) is a contraindication for Orthotopic Heart Transplantation (OHT) with a recommendation that HT candidates be free from CS for at minimum 6 months prior to HT. Animal studies have shown that a history of CS is associated with increased risk of allograft rejection, but few studies have examined the association of past CS and HT outcomes. Methods: Data were analyzed from HT recipients captured in the United Network for Organ Sharing (UNOS) transplant registry. Adults aged 18–79 who underwent HT from 1987 to 2018 and with data for all covariates (N = 32,260) were included in this study. The cohort was categorized by past smoking history (CS vs non-CS). Post-transplant outcomes of interest included survival, graft failure, treated rejection, malignancy and hospitalization for infection. Baseline characteristics were compared between the two groups using the chi-squared analysis. Unadjusted associations between CS and patient survival were determined using the Kaplan-Meier estimations and confounding was addressed using multivariable Cox proportional hazards models. Results: HT recipients with a history of CS were older (55 vs 50, p = <0.0001), more likely to be Caucasian (75.7 vs 62.3, p = <0.0001), male (81.7 vs 68.2, p =< 0.0001), and diabetic (27.4 vs 24.4, p =< 0.0001). CS was associated with significantly worse survival (HR: 1.23, p < 0.0001). A history of CS was also associated with increased risk of acute rejection (OR: 1.20, p < 0.0001), hospitalization for infection (OR:1.24, p < 0.0001), graft failure (OR:1.23, p < 0.0001) and post-transplant malignancy (OR:1.43, p < 0.0001). Conclusion: A history of CS is associated with increased risk of adverse events post OHT.

Abstract
AbstractThe rapid cycling variant of bipolar disorder is defined as the occurrence of four periods of either manic or depressive illness within 12 months. Patients suffering from this variant of bipolar disorder have an unmet need for effective treatment. This review examines two major studies in an attempt to update understanding of the current therapies available to treat rapid cycling patients. The first trial compares lamotrigine versus placebo in 182 patients studied for 6 months. The second is a recently completed, 20-month trial comparing divalproate and lithium in 60 patients. Both trials had a double-blind, randomized parallel-group design. The data from the latter study indicate that there are no large differences in efficacy between lithium and divalproate in the long-term treatment of rapid cycling bipolar disorder. In addition, lamotrigine has the potential to complement the spectrum of lithium and divalproate through its greater efficacy for depressive symptoms.

Abstract
A 61 year old male presented to chest clinic with a lung abscess. This ruptured and resulted in an empyema that required a small bore chest drain. Pus started bypassing the drain, spilling out subcutaneously. This was probably due to the impending formation of an empyema necessitans. To stem the flow, a large bore drain was inserted. An ambulatory bag was connected to the end of that drain which enabled outpatient management through the ambulatory care unit over a ten week period. The chest drain stayed in for nine weeks. Risk stratification using the RAPID score was applied. This is a routine medical presentation with well-known and accepted investigations with routine organisms (mixed aerobic and anaerobic microbiota) and treatment with classical broad spectrum antibiotics. The striking feature of the case is that with strict supervision, patient education and motivation, ambulatory management is perfectly feasible and safe.

Abstract
BACKGROUND Donation after circulatory death (DCD) has the potential to significantly alleviate the shortage of transplantable lungs. We report our initial experience with the use of portable ex vivo lung perfusion (EVLP) with the Organ Care System Lung device for evaluation of DCD lungs. METHODS We performed a retrospective review of the DCD lung transplantation (LTx) experience at a single institution through the use of a prospective database. RESULTS From 2011 to 2015, 208 LTx were performed at the University of Alberta, of which 11 were DCD LTx with 7 (64%) that underwent portable EVLP. DCD lungs preserved with portable EVLP had a significantly shorter cold ischemic time (161 ± 44 vs 234 ± 60 minutes, P = .045), lower grade of primary graft dysfunction at 72 hours after LTx (0.4 ± 0.5 vs 2.1 ± 0.7, P = .003), similar mechanical ventilation time (55 ± 44 vs 103 ± 97 hours, P = .281), and hospital length of stay (29 ± 11 vs 33 ± 10 days, P = .610). All patients were alive at 1-year follow-up after LTx with improved functional outcomes and acceptable quality of life compared with before LTx, although there were no intergroup differences. CONCLUSIONS In our pilot cohort, portable EVLP was a feasible modality to increase confidence in the use of DCD lungs with validated objective evidence of lung function during EVLP that translates to acceptable clinical outcomes and quality of life after LTx. Further studies are needed to validate these initial findings in a larger cohort.

Abstract
Meningococcal disease has had devastating consequences in Northern Ireland since its first description locally in 1859. The incidence of this disease has significantly declined in recent years, however it is important to understand reasons for this changing epidemiology and to acknowledge the diagnostic and clinical management developments that have been made locally. This review aims to examine the changing face of this disease in Northern Ireland over the years, with particular reference to local disease prevention, epidemiology, diagnosis, clinical treatment and management, post-disease sequelae and the role of meningitis charities locally, in terms of patient support and research.

Abstract
BACKGROUND Hepatitis B e antigen (HBeAg) seroconversion is a treatment endpoint for HBeAg-positive CHB, and a necessary precursor to HBsAg loss. Biomarkers that predict serological outcomes would be useful. AIM To evaluate the utility of measuring HBeAg levels for predicting HBeAg seroconversion and HBsAg loss under long-term tenofovir (TDF) therapy. METHODS A total of 266 patients were enrolled into a phase III study of TDF vs adefovir (ADV) for 48 weeks in HBeAg-positive patients, followed by open-label TDF up to 384 weeks. Serum HBeAg levels were measured for subjects with samples available at both baseline and week 24 of treatment (n = 200). Analysis compared subjects who achieved HBeAg seroconversion by week 384 vs no HBeAg seroconversion. RESULTS HBeAg seroconversion rate was 52% by week 384. Time to HBeAg seroconversion was 80 weeks (IQR: 36-162). HBeAg decline at week 24 was associated with HBeAg seroconversion (1.63 vs 0.90 log10 PEIU/mL, P = .002). The optimal threshold for identifying HBeAg seroconversion was HBeAg decline ≥2.2 log10 PEIU/mL at week 24, with HBeAg seroconversion achieved by 76% of patients, compared to 44% if HBeAg decline <2.2 log10 (P < .0001). HBeAg decline ≥2.2 log10 PEIU/mL at week 24 was associated with HBsAg loss in genotype A or D patients (38% vs 15%, P = .03). Precore/basal core promotor variants were associated with lower baseline HBeAg levels, but not HBeAg seroconversion. CONCLUSION Decline in HBeAg levels by week 24 was associated with HBeAg seroconversion and HBsAg loss in HBeAg-positive chronic hepatitis B patients treated with long-term TDF.
