Abstract
INTRODUCTION Recombinant factor IX (rFIX) and recombinant FIX Fc fusion protein (rFIXFc) are standard half-life and extended half-life FIX replacement therapies, respectively, and represent established treatment options indicated for adults and children with haemophilia B. These FIX replacement therapies can be administered as prophylaxis (to prevent bleeding) or 'on-demand' (to stop bleeding). This analysis aimed to estimate the cost-effectiveness of once-weekly prophylaxis with rFIXFc versus on-demand treatment with rFIX in patients with haemophilia B without inhibitors in the Italian healthcare setting. METHODS A Markov model was developed to assess a hypothetical cohort of adolescent or adult male patients (≥ 12 years) with haemophilia B (FIX level of ≤ 2 IU/dL) without inhibitors. Model inputs were derived from the pivotal phase 3 clinical studies for rFIXFc and rFIX, published literature and assumptions when published data were unavailable. The model employed a lifelong time horizon with 6-monthly transitions between health states, and it estimated total costs, total quality-adjusted life years (QALYs), number of bleeds, number of surgeries and incremental cost-effectiveness ratio. RESULTS rFIXFc prophylaxis was associated with lower total costs per patient (€5,308,625 versus €6,564,510) and greater total QALYs per patient (15.936 versus 11.943) compared with rFIX on-demand; rFIXFc prophylaxis was therefore the dominant treatment strategy. The model also demonstrated that rFIXFc prophylaxis was associated with fewer incremental bleeds (- 682.29) and surgeries (- 0.39) compared with rFIX on-demand. CONCLUSIONS rFIXFc prophylaxis provides improved health outcomes and lower costs, and represents a cost-effective treatment option compared with rFIX on-demand for adolescent and adult male patients with haemophilia B. This comparative assessment of cost-effectiveness should help to inform both clinicians and healthcare policy makers when making treatment decisions for patients with haemophilia B.

Abstract
INTRODUCTION Cancer-associated thrombosis (CAT) is a significant concern among patients with malignant diseases, leading to increased mortality. While current guidelines recommend primary thromboprophylaxis for venous thromboembolism (VTE) in medium-to-high-risk outpatients, this practice remains controversial. A better understanding of primary thromboprophylaxis is crucial, yet there is a lack of Real-World Evidence (RWE) in Portugal. AIMS This RWE study aimed to elucidate primary thromboprophylaxis practices among cancer outpatients in Portugal. METHODS A five-year observational multicentric study in eight Portuguese health institutions enrolled 124 adult cancer outpatients under primary thromboprophylaxis for VTE. The endpoints were CAT, bleeding, cancer progression and death. RESULTS High thrombotic risk tumours were prevalent, with 57% (71) of the patients presenting with pancreatic and gastric cancers. Regarding primary thromboprophylaxis, 55% (68) received Low-Molecular-Weight Heparin (LMWH). VTE was presented in 11% (14) of the patients and major bleeding in 2% (2). Vascular compression, elevated D-dimer and previous VTE were significantly associated with VTE occurrence under primary thromboprophylaxis. The Onkotev model was shown to be the best risk assessment model (RAM) in this population (p = 0.007). CAT patients exhibited a lower progression-free survival than non-CAT patients (p = 0.021), while thrombosis did not influence overall survival (p = 0.542). CONCLUSION Primary thromboprophylaxis in medium-to-high-risk cancer outpatients is a safe and effective practice in real-world settings. This study is the first Portuguese RWE on primary thromboprophylaxis, highlighting evidence for improving prophylactic strategies in this population.

Abstract
BACKGROUND Hemorrhage is a significant cause of death in trauma patients. There is evidence that individuals with blood group O have higher rates of non-traumatic haemorrhage. It has been suggested that blood group O may be associated with higher mortality in trauma, however existing evidence is limited and conflicting. OBJECTIVE A systematic review was conducted to evaluate the impact of ABO blood group on mortality in trauma patients. METHODS MEDLINE via OVID, the Cochrane library and grey literature were searched to identify studies investigating the effect of ABO blood group on mortality of trauma patients admitted to hospital. PRISMA guidelines were followed throughout, study quality was assessed using CASP checklists and certainty of evidence was evaluated using GRADE. Meta-analysis was precluded by significant study heterogeneity. RESULTS 180 relevant records were screened and seven studies met inclusion criteria, representing 12,240 patients. Two studies found that there was a higher mortality in blood group O compared to other ABO groups. Included studies had substantial variability in methods and population. Study quality was variable with certainty of evidence rated as very low. CONCLUSIONS There is insufficient evidence to definitively establish an association between mortality and ABO group in trauma patients. In an age of increasingly individualised care, there is a need to determine the existence and cause for any association through further studies across multiple settings, trauma mechanisms and populations.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are implied in blood-brain barrier degradation and haemorrhagic transformation following ischaemic stroke, but their local relevance in the hyperacute disease phase is unknown. We aimed to examine ultra-early MMP-9 and MMP-2 release into collateral blood vessels, and to assess its prognostic value before therapeutic recanalisation by endovascular thrombectomy (EVT). METHODS We report a cross-sectional proof-of-concept study including patients undergoing EVT for large-vessel ischaemic stroke at the University Hospital Würzburg, Germany. We obtained liquid biopsies from the collateral circulation before recanalisation, and systemic control samples. Laboratory workup included quantification of MMP-9 and MMP-2 plasma concentrations by cytometric bead array, immunohistochemical analyses of cellular MMP-9 and MMP-2 expression, and detection of proteolytic activity by gelatine zymography. The clinical impact of MMP concentrations was assessed by stratification according to intracranial haemorrhagic lesions on postinterventional computed tomography (Heidelberg Bleeding Classification, HBC) and early functional outcome (modified Rankin Scale, mRS). We used multivariable logistic regression, receiver-operating-characteristic (ROC) curves, and fixed-level estimates of test accuracy measures to study the prognostic value of MMP-9 concentrations. FINDINGS Between August 3, 2018, and September 16, 2021, 264 matched samples from 132 patients (86 [65.2%] women, 46 [34.8%] men, aged 40-94 years) were obtained. Median (interquartile range, IQR) MMP-9 (279.7 [IQR 126.4-569.6] vs 441 [IQR 223.4-731.5] ng/ml, p < 0.0001) but not MMP-2 concentrations were increased within collateral blood vessels. The median MMP-9 expression level of invading neutrophils was elevated (fluorescence intensity, arbitrary unit: 2276 [IQR 1007-5086] vs 3078 [IQR 1108-7963], p = 0.0018). Gelatine zymography experiments indicated the locally confined proteolytic activity of MMP-9 but not of MMP-2. Pretherapeutic MMP-9 release into stroke-affected brain regions predicted the degree of intracerebral haemorrhages and clinical stroke severity after recanalisation, and independently increased the odds of space-occupying parenchymal haematomas (HBC1c-3a) by 1.54 times, and the odds of severe disability or death (mRS ≥5 at hospital discharge) by 2.33 times per 1000 ng/ml increase. Excessive concentrations of MMP-9 indicated impending parenchymal haematomas and severe disability or death with high specificity. INTERPRETATION Measurement of MMP-9 within collateral blood vessels is feasible and identifies patients with stroke at risk of major intracerebral haemorrhages and poor outcome before therapeutic recanalisation by EVT, thereby providing evidence of the concept validity of ultra-early local stroke biomarkers.

Abstract
AIMS We aimed to elucidate the association between malnutrition and the occurrence of bleeding events in patients with heart failure. METHODS AND RESULTS We evaluated the nutritional status of patients with heart failure [n = 2044, median (inter-quartile range) age 69.0 (59.0-78.0) years, 1209 (59.1%) males] using the Geriatric Nutritional Risk Index (GNRI). The primary endpoint was a composite of bleeding events such as haemorrhagic stroke or gastrointestinal bleeding. According to the survival classification and regression tree analysis, the accurate cut-off point of GNRI for predicting the primary endpoint was 106.2. We divided the patients into two groups based on GNRI levels: high GNRI group (GNRI ≥ 106.2, n = 606, 29.6%) and low GNRI group (GNRI < 106.2, n = 1438, 70.4%). We compared the patients' characteristics and prognosis between the two groups. The low GNRI group was older [72.0 (63.0-79.0) vs. 63.0 (53.0-73.0) years, P < 0.001] and had a lower prevalence of male sex (56.9% vs. 64.5%, P = 0.001). There were no differences in the use of antiplatelet agents and anticoagulants between the two groups. Levels of B-type natriuretic peptide were higher [321.1 (123.3-667.4) vs. 111.6 (42.6-235.4) pg/mL, P < 0.001] and levels of haemoglobin were lower [12.4 (10.8-13.7) vs. 14.2 (12.9-15.4) g/dL, P < 0.001] in the low GNRI group. The Kaplan-Meier analysis demonstrated that bleeding event rates were higher in the low GNRI group (log-rank P < 0.001). The multivariable Cox proportional hazard analysis revealed that low GNRI (hazard ratio 1.952, 95% confidence interval 1.002-3.805, P = 0.049) was associated with bleeding events. CONCLUSIONS Heart failure patients with poor nutritional status, determined by GNRI under 106.2, experienced high bleeding event rates. Comprehensive management is required to avoid bleeding event in those populations.

Abstract
BACKGROUND Guidelines advise 50 % and 25 % dose reduction of the therapeutic nadroparin dose (86 IU/kg) in patients with eGFR 15-29 and 30-60 ml/min respectively. For monitoring, peak anti-Xa levels are suggested. Data lack whether this results in therapeutic anti-Xa levels or in anti-Xa levels that are comparable to those of patients without renal impairment. AIMS To determine dose ranges in patients with renal impairment that result in therapeutic anti-Xa levels and to determine the percentage of the 86 IU/kg dose that results in anti-Xa levels normally occurring in patients without renal impairment. METHODS A retrospective cohort study was conducted in five hospitals. Patients ≥18 years of age, with an eGFR ≥ 15 ml/min were included. The first correctly sampled peak (i.e. 3-5 h after ≥ third administration, regardless of dose per patient) was included. Simulated prediction models were developed using multiple linear regression. RESULTS 770 patients were included. eGFR and hospital affected the association between dose and anti-Xa level. The doses for peak anti-Xa levels of 0.75 IU/ml differed substantially between hospitals and ranged from 55 to 91, 65-359 and 68-168 IU/kg in eGFR 15-29, 30-60 and > 60 ml/min/1.73m2, respectively. In eGFR 15-29 and 30-60 ml/min/1.73m2, doses of 75 % and 91 % of 86 IU/kg respectively, were needed for anti-Xa levels normally occurring in patients with eGFR > 60 ml/min. CONCLUSION We advise against anti-Xa based dose-adjustments as long as anti-Xa assays between laboratories are not harmonized and an anti-Xa target range is not validated. A better approach might be to target levels similar to eGFR > 60 ml/min/1.73m2, which are achieved by smaller dose reductions.

Abstract
Amniotic embolism remains the 3rd leading cause of maternal death in France, with 21 maternal deaths over the 2016-2018 triennium. The women who died were more likely to be obese (25%), to benefit from induction of labor (71%) and be cared in a maternity hospital <1500 deliveries/year (45%), compared with the reference population (ENP 2016). The symptom occurred mainly during labor (95%) and the course was rapid, with a symptom-to-fatality interval of 4hours 45minutes (min: 25minutes - max: 8 days). Preventability was proposed for 35% of the deaths assessed, with areas for improvement identified in terms of technical skills (haemostasis procedures, management of polytransfusion), non-technical skills (communication) and health care organization (human resources, vital emergency plan, wide access to PSL). An autopsy was performed in 38% of deaths.

Abstract
Between 2016 and 2018, 20 maternal deaths were related to obstetric haemorrhage, excluding haemorrhage in the first trimester of pregnancy, representing a mortality ratio of 0.87 per 100,000 live births (95% CI 0.5 -1.3). Obstetric haemorrhage is the cause of 7.4% of all maternal deaths up to 1 year, 10% of maternal deaths within 42days, and 21% of deaths directly related to pregnancy (direct causes). Between 2001 and 2018, maternal mortality from obstetric haemorrhage has been considerably reduced, from 2.2deaths per 100,000 live births in 2001-2003 to 0.87 in the period presented here. Nevertheless, obstetric haemorrhage is still one of the main direct causes of maternal death, and remains the cause with the highest proportion of deaths considered probably (53%) or possibly (42%) preventable according to the CNEMM's collegial assessment (see chapter 3). The preventable factors reported are related to inadequate content of care in 94% of cases and/or organisation of care in 44% of cases. In this triennium, maternal death due to haemorrhage occurred mainly in the context of caesarean delivery (65% of cases, i.e. 13/20), and mostly in the context of emergency care (12/13). The main causes of obstetric haemorrhage were uterine rupture (6/20) in unscarred uterus or in association with placenta accreta, and surgical injury during the caesarean delivery (5/20). Every maternity hospital, whatever its resources and/or technical facilities, must be able to plan any obstetric haemorrhage situation that threatens the mother's vital prognosis. Intraperitoneal occult haemorrhage following caesarean section and uterine rupture require immediate surgery with the help of skilled surgeon resources with early and appropriate administration of blood products.

Abstract
BACKGROUND Major traumatic haemorrhage is potentially preventable with rapid haemorrhage control and improved resuscitation techniques. Although advances in prehospital trauma management, haemorrhage is still associated with high mortality. The aim of this study was to use a recent pragmatic transfusion-based definition of major bleeding to characterize patients at risk of major bleeding and associated outcomes in this cohort after trauma. METHODS This was a retrospective cohort study including all trauma patients (n = 7020) admitted to a tertiary trauma center from January 2015 to June 2020. The major bleeding cohort (n = 145) was defined as transfusion of 4 units of any blood components (red blood cells, plasma, or platelets) within 2 h of injury. Univariate and multivariable logistic regression analyses were performed to identify risk factors for 24-hour and 30-day mortality post trauma admission. RESULTS In the major bleeding cohort (n = 145; 145/7020, 2.1% of the trauma population), there were 77% men (n = 112) and 23% women (n = 33), median age 39 years [IQR 26-53] and median Injury Severity Score (ISS) was 22 [IQR 13-34]. Blunt trauma dominated over penetrating trauma (58% vs. 42%) where high-energy fall was the most common blunt mechanism and knife injury was the most common penetrating mechanism. The major bleeding cohort was younger (OR 0.99; 95% CI 0.98 to 0.998, P = 0.012), less female gender (OR 0.66; 95% CI 0.45 to 0.98, P = 0.04), and had more penetrating trauma (OR 4.54; 95% CI 3.24 to 6.36, P = 0.001) than the rest of the trauma cohort. A prehospital (OR 2.39; 95% CI 1.34 to 4.28; P = 0.003) and emergency department (ED) (OR 6.91; 95% CI 4.49 to 10.66, P = 0.001) systolic blood pressure < 90 mmHg was associated with the major bleeding cohort as well as ED blood gas base excess < -3 (OR 7.72; 95% CI 5.37 to 11.11; P < 0.001) and INR > 1.2 (OR 3.09; 95% CI 2.16 to 4.43; P = 0.001). Emergency damage control laparotomy was performed more frequently in the major bleeding cohort (21.4% [n = 31] vs. 1.5% [n = 106]; OR 3.90; 95% CI 2.50 to 6.08; P < 0.001). There was no difference in transportation time from alarm to hospital arrival between the major bleeding cohort and the rest of the trauma cohort (47 [IQR 38;59] vs. 49 [IQR 40;62] minutes; P = 0.17). However, the major bleeding cohort had a shorter time from ED to first emergency procedure (71.5 [IQR 10.0;129.0] vs. 109.00 [IQR 54.0; 259.0] minutes, P < 0.001). In the major bleeding cohort, patients with penetrating trauma, compared to blunt trauma, had a shorter alarm to hospital arrival time (44.0 [IQR 35.5;54.0] vs. 50.0 [IQR 41.5;61.0], P = 0.013). The 24-hour mortality in the major bleeding cohort was 6.9% (10/145). All fatalities were due to blunt trauma; 40% (4/10) high energy fall, 20% (2/10) motor vehicle accident, 10% (1/10) motorcycle accident, 10% (1/10) traffic pedestrian, 10% (1/10) traffic other, and 10% (1/10) struck/hit by blunt object. In the logistic regression model, prehospital cardiac arrest (OR 83.4; 95% CI 3.37 to 2063; P = 0.007) and transportation time (OR 0.95, 95% CI 0.91 to 0.99, P = 0.02) were associated with 24-hour mortality. RESULTS Early identification of patients at high risk of major bleeding is challenging but essential for rapid definitive haemorrhage control. The major bleeding trauma cohort is a small part of the entire trauma population, and is characterized of being younger, male gender, higher ISS, and exposed to more penetrating trauma. Early identification of patients at high risk of major bleeding is challenging but essential for rapid definitive haemorrhage control.

Abstract
BACKGROUND Women are counseled preconceptionally about the potential risks of rAML progression and chance of complications during and due to pregnancy. However, a systematic search investigating the evidence on which this advice is based does not exist. The aim of this systematic review is to determine the effect of pregnancy on renal angiomyolipoma (rAML) size and risk of haemorrhage in patients with tuberous sclerosis complex (TSC). METHODS We searched PubMed, EMBASE, Medline and ClinicalTrials.gov using terms for "renal angiomyolipoma" and "pregnancy". English-language articles published between January 1st 2000, and December 31st 2020 of which full-text was available were included. The initial search resulted in 176 articles. After the screening process we included 45 case reports and 1 retrospective study. For the retrospective study we assessed the risk of bias using the Newcastle-Ottawa Scale. We included articles about renal AML and pregnancy with and without an established diagnosis of TSC. From these articles we recorded the rAML sizes and rAML complications. RESULTS Seven case reports, from a total of 45 case reports, provided follow-up data on renal AML size (these were all cases of renal AML without a known diagnosis of TSC). Of these cases, renal AML size decreased in one patient, was stable in one patient, increased in three patients and fluctuated in two others. Renal AML size of women who suffered a haemorrhage were significantly larger (12.1 ± 4.6 cm) than rAMLs of women who did not suffer a haemorrhage (8.3 ± 3.2 cm). Data from the retrospective study showed no difference in renal complications between the women with and without a history of pregnancy. Haemorrhage occurred in 30% of the women with a history of pregnancy (n = 20) and in 11% in the patients without a history of pregnancy (n = 2), however this retrospective study had methodological limitations. CONCLUSION The effect of pregnancy on renal AML size and complications in patients with TSC is unclear. More research is needed to determine the risk of pregnancy on TSC-associated kidney disease in TSC patient.

Abstract
BACKGROUND Reducing blood loss during excisional surgery in burn patients remains a challenge. Tranexamic acid during surgery can potentially reduce blood loss. The use of tranexamic acid during excisional surgery in burn patients has recently been described in a review and meta-analysis. However, quality assessment on studies included was not performed and this review did not apply independent reviewers. Quality assessment of studies investigating the effectiveness of tranexamic acid in burn patients is crucial before concusions can be drawn. Therefore, we conducted a systematic review and meta-analysis of the literature investigating the effectiveness of tranexamic acid in burn patients undergoing surgery. METHODS A systematic review and meta-analysis of the literature was conducted. The study was pre-registered in PROSPERO database (CRD42023396183). RESULTS Five studies including two randomised controlled trials (RCTs) with a total of 303 patients were included. Risk of bias of the included studies was moderate to high. Individual results of the studies were heterogeneous. In three studies of moderate quality the administration of tranexamic acid resulted in a reduction of blood loss per unit excised area, accounting as moderate level of evidence. In two low-quality studies and one moderate quality study the administration of tranexamic acid resulted in a reduction of transfused packed Red Blood Cells (pRBC's), accounting for moderate level of evidence. Postoperative haemoglobin levels were higher after tranexamic acid administration in one study, accounting for insufficient evidence. Meta-analysis pooling overall blood loss from two separate RCTs failed to detect a statistically significant reduction. Substantial heterogeneity was observed. CONCLUSIONS Moderate level of evidence indicates that tranexamic acid reduces blood loss per unit of excised area and transfusion of packed Red Blood Cells. Results indicate that tranexamic acid can be beneficial in burn patients undergoing surgery. More high-quality research is needed to confirm these results. Future studies should focus on the dosing of tranexamic acid, the administration approaches, and even consider combining these approaches. TRIAL REGISTRATION PROSPERO: CRD42023396183.

Abstract
Haemorrhagic shock is frequent in critical care settings and responsible for a high mortality rate due to multiple organ dysfunction and coagulopathy. The management of critically ill patients with bleeding and shock is complex, and treatment of these patients must be rapid and definitive. The administration of large volumes of blood components leads to major physiological alterations which must be mitigated during and after bleeding. Early recognition of bleeding and coagulopathy, understanding the underlying pathophysiology related to specific disease states, and the development of individualised management protocols are important for optimal outcomes. This review describes the contemporary understanding of the pathophysiology of various types of coagulopathic bleeding; the diagnosis and management of critically ill bleeding patients, including major haemorrhage protocols and post-transfusion management; and finally highlights recent areas of opportunity to better understand optimal management strategies for managing bleeding in the intensive care unit (ICU).

Abstract
AIMS Although frail patients with atrial fibrillation (AF) carry a high risk of stroke and treatment-related bleeding complications, evidence for the safety and effectiveness of anticoagulation remains sparse. This study investigated the effectiveness and safety of direct oral anticoagulant (DOAC) vs. warfarin in frail AF patients. METHODS AND RESULTS Nationwide registry-based cohort study including 32 048 anticoagulation naïve frail patients (median age 80 years, 53% female) with incident AF during 2012-20. Frailty was assessed using the hospital frailty risk score. To address baseline confounding, we applied inverse probability of treatment weighting (IPTW) and marginal structural models with weighted pooled regression to compute weighted hazard ratios (wHRs) and risk differences for thromboembolism and major bleeding comparing specific DOAC doses with warfarin. After AF diagnosis, 6747 (21.1%) initiated warfarin, 17 076 (50.3%) initiated standard-dose DOAC, and 9179 (28.6%) initiated reduced-dose DOAC. Comparative effectiveness analyses in the IPTW pseudo-populations revealed similar thromboembolism risk between standard-dose DOAC and warfarin [wHR 0.95, 95% confidence interval (CI) 0.80-1.13] and between reduced-dose DOAC and warfarin (wHR 0.97, 95% CI 0.77-1.23). The 1-year thromboembolic event-free survival difference was -0.2% for DOAC, regardless of dosing, vs. warfarin. Major bleeding risk was significantly lower with standard-dose DOAC (wHR 0.69, 95% CI 0.59-0.87) and reduced-dose DOAC (wHR 0.67, 95% CI 0.55-0.81) vs. warfarin. The 1-year bleeding risk difference with DOAC ranged from -1.3% to -3.0%. CONCLUSION Our findings indicate comparable thromboembolism risk and significantly lower bleeding risk with both standard and reduced DOAC regimens compared with warfarin in frail AF patients in routine care.

Abstract
BACKGROUND We performed a meta-analysis to assess the effectiveness and safety of tranexamic acid in patients with traumatic brain injury (TBI). METHODS We searched the literature for articles evaluating the effectiveness and safety of tranexamic acid (TXA) in TBI published between January 2012 and January 2021, and identified 8 studies with a total of 10860 patients: 5660 received TXA and 5200 served as controls. We used a dichotomous or continuous approach with a random or fixed-effect model to assess the efficacy and safety of TXA in TBI, and calculated the mean difference (MD) and odds ratio (OR) with the corresponding 95% confidence interval. RESULTS In patients with TBI, early administration of TXA was associated with a greater relative benefit (MD -2.45; 95% CI = -4.78 to -0.12; p=0.04) and less total haematoma expansion (MD - 2.52; 95% CI = -4.85 to -0.19; p=0.03) compared to controls. There were no statistically significant differences in mortality (OR 0.94; 95% CI=0.85-1.03; p=0.18), presence of progressive haemorrhage (OR 0.75; 95% CI=0.56-1.01; p=0.06), need for neurosurgery (OR 1.15; 95% CI=0.66-1.98; p=0.63), high Disability Rating Scale score (OR 0.90; 95% CI=0.56-1.45; p=0.68), and incidence of ischaemic or thromboembolic complications (OR 1.34; 95% CI=0.33-5.46; p=0.68) between TBI patients treated with TXA and controls. CONCLUSIONS Early administration of TXA in TBI patients may have a greater relative benefit and may inhibit haematoma expansion. There were no significant differences in mortality, presence of progressive haemorrhage, need for neurosurgery, high Disability Rating Scale score, and incidence of ischaemic or thromboembolic complications between TBI patients treated with TXA and controls. Further studies are needed to validate these results.

Abstract
BACKGROUND Osteogenesis Imperfecta (OI) is characterised by bone fragility. Among several features, easy bruising and multiple case reports on haemorrhagic events have been reported. This paper describes the diverse manifestations of bleeding and bruising in a large cohort of 328 OI patients. The aim of this study is to provide insight in the diverse aspects and therapeutic considerations of bleedings in OI. METHODS This descriptive cohort study was conducted at the National Expert Center for adults with OI in the Netherlands. Bleeding was assessed by the validated self-bleeding assessment tool (Self-BAT) The tool was distributed among 328 adults with different clinically confirmed types of OI. RESULTS 195 of 328 invited patients (completion rate 60%) with OI type 1 (n = 144), OI type 3 (n = 17) and OI type 4 (n = 34), aged between 18 and 82 years, completed the tool. Self-BAT scores were above the normal range in 42% of all patients. For males Self-BAT scores were increased in 37% with a mean score of 3.7, ranged between 0 and 18. For females the Self-BAT scores were increased in 44% with a mean of 5.4 and a range of 0-24. No statistical differences in OI subtypes were found. CONCLUSIONS Bleeding tendency appears to be a relevant complication in OI patients as this study confirms the presumption of bleeding tendency. There are specific recommendations to clinicians who treat OI patients to consider an assessment of bleeding tendency and use potential interventions to reduce haemorrhagic complications and improve quality of life.

Abstract
INTRODUCTION AND IMPORTANCE We present the case of a 17 years old girl with per rectal haemorrhage secondary to pelvic arteriovenous malformations (AVM) and potentially haemorrhoids. Pelvic AVMs are rare and extremely variable in their clinical presentation, size and location and pose a therapeutic challenge. Focus has turned towards interventional radiological procedures with angioembolisation as the main treatment form for pelvic AVMs. CASE PRESENTATION A 17 years old girl presented to a rural hospital with significant per rectal bleeding requiring transfer to a tertiary centre with interventional radiology capabilities. Diagnostic imaging determined the presence of a pelvic AVM as well as haemorrhoid. She had no prior history of haemorrhoids, per rectal bleeding or per vaginal bleeding. Further diagnostic imaging including a digital subtraction angiography and MRI pelvis was performed and her case was discussed at a multidisciplinary meeting where the decision was made for angioembolisation of a large right rectal AVM as well as precautionary banding of haemorrhoids that had developed secondary to outflow obstruction. A repeat CT mesenteric angiogram a month later demonstrated diminished appearances of the rectal AVM. CLINICAL DISCUSSION Pelvic AVMs are a rare entity and are not a common cause for per rectal bleeding. There is currently no direct consensus on the optimum management of complex pelvic AVMs particularly those that present with a second pathology such as haemorrhoids. Surgical management often results in recurrence or rapid progression of the AVM lesion and recruitment of new blood supply further complicates the problem. Selective embolisation allows for control of haemorrhage and utilises chemical agents as well as detachable coils and balloons. However, postoperative pain and swelling can still be expected and multiple transcatheter embolisations may be required. CONCLUSION The treatment of symptomatic pelvic AVMs is complex and requires a multidisciplinary approach with careful radiological planning prior to embolisation. Angioembolisation is becoming increasingly prevalent and multiple embolisation procedures may be required to reach the desired therapeutic effect.

Abstract
OBJECTIVES The aim of the study is to assess obstetric and fetal outcomes of Jehovah's Witnesses (JWs) mothers in an inner city teaching hospital, as well as to examine the acceptance rates of various blood fractions and blood transfusion alternatives. METHODS Case series to evaluate the maternal and fetal outcomes of JWs over a nine period between 2013 and 2021. RESULTS There were 146 pregnancies extracted from our database, of which 10 were early pregnancy losses. Data from 136 deliveries > 24 weeks' gestation were assessed, with a mean maternal age and gestational age of 30.26 (± 5.4) years and 38.7 (± 5.3) weeks, respectively. 57% had normal vaginal deliveries, 8% had instrumental births and 35% had caesarean births. Mean estimated blood loss at caesarean was 575 (± 305.6) mls, while the overall mean estimated loss was 427.8 (± 299.8) mls. Cell salvage was performed in all caesarean sections but autologous transfusion was only necessary for 26%. Consultant presence was documented in 62% of caesarean births. The mean birthweight and 5-min Apgar scores were 3.31 (± 0.05) kg and 9.1 (± 0.09), respectively. There were no maternal deaths or admissions to the adult intensive care unit and the most serious complication was a uterine rupture following a trial of scar, after which the baby required cooling for hypoxic ischaemic encephalopathy. CONCLUSIONS Pregnant JWs received obstetric care led by senior clinicians, with optimisation of haematinics, minimizing of blood loss at delivery and access to technology such as cell salvage.

Abstract
BACKGROUND AND AIMS The effect of surgical treatment for spontaneous intracerebral hemorrhage (ICH) remains uncertain. We conducted an observational retrospective cohort study on supra-centimeter spontaneous ICH treated with either neurosurgical or conservative management. The baseline demographics and risk factors were correlated with in-hospital mortality and 3 and 6-month survival rates stratified by management. METHODS We included all patients with evidence of spontaneous ICH > 1 cm detected by CT and admitted between august 2020 and march 2021 to the "SMM" Hospital in Perugia. RESULTS Onehundredandtwentytwo patients were included in the study, and 45% (n.55) were surgically treated. The mean age was 71.9 ± 15.3, and 61% (n.75) were males. Intra-hospital mortality ended up being 31% (n.38), 3 months-survival was 63% (n.77) and 6 months-survival was 60% (n.73). From the multivariate analysis of the surgical patients versus medical patient, we observed that the surgical patients were younger (67.5 ± 14.9 vs 75.5 ± 14.7 y; OR 0.87; Cl 95% 0.85-0.94; p 0.001), with greater ICH volume at the onset (61 ± 39.4 cc vs 51 ± 64 cc; OR 1.03; Cl 95% 1.005-1.07; p 0.05), more midline shift (7.61 ± 5.54 mm vs 4.09 ± 5.88 mm; OR 1.37; Cl 95% 1.045-1.79; p 0.023), and a higher ICH score (3 vs 2 mean ICH score; OR 21.12; Cl 95% 2.6-170.6; p 0.004). Intra-hospital mortality in the surgical group and in the conservative treatment group was respectively 33% vs 30%, 3 month-survival was 64% vs 63% and 6 month- survival were 60% in both groups. CONCLUSIONS Our patient cohort shows no overall benefit from surgery over conservative treatment, but surgical patients were younger and had larger ICH volume.

Abstract
AIMS We assessed the cumulative incidence of recurrent stroke, major bleeding and all-cause mortality associated with restarting antithrombotic treatment, in patients experiencing an anticoagulation-related event (stroke or major bleeding), occurred during anticoagulation therapy for AF. METHODS AND RESULTS We performed a retrospective population-based analysis on linked claims data of patients resident in the Veneto Region, treated with DOACs for AF and discharged (2013-2020) from the hospital for stroke, intracranial haemorrhage (ICH), and major bleeding. To adjust for competing risk of death and reduce confounding, we started the follow up after a 120-days blanking period, counting events in patients resuming oral anticoagulation versus those that did not. Risks of all-cause mortality, ischemic stroke (IS)intracranial haemorrhage (ICH), and other major bleeding events (MB) were estimated with multivariable Cox proportional hazard models and propensity score to adjust for differences in baseline characteristics. Overall, 1029 patients (mean age 77 years) were included in the final cohort: 23% experienced an IS, 18% an ICH, and 59% MB. Of these, 77% resumed anticoagulation. The cumulative incidence of events was significantly lower in patients resuming therapy. In the multivariable analysis considering age, sex and propensity score as covariates, resumption of anticoagulation significantly reduced the risk of a cumulative event (HR 0.45, 95%CI 0.35-0.57, p < 0.01). Stratifying for the index event, among patients with IS (92% resumed therapy), we observed a risk reduction of 81%; in patients with ICH (64% resumed therapy), we observed a risk reduction of 64% and for patients with MB (76% resuming therapy), we observed a risk reduction of 49%. CONCLUSIONS In patients with AF who experienced an anticoagulation-related event, resuming oral anticoagulation was associated with better outcomes for all-cause mortality and subsequent events as compared with patients who did not resume treatment.

Abstract
BACKGROUND Immune thrombocytopenic purpura (ITP) is a rare auto-antibody mediated disease of isolated thrombocytopenia (<100,000/μL) with normal haemoglobin levels and leukocyte counts. Only a small number of ITP cases have been reported with accompanying ophthalmological findings. Herein, we report an ITP case with demonstrative retinal haemorrhages. CASE PRESENTATION A fifty-five-year-old woman with a known history of type 2 diabetes mellitus was referred to our clinic with blurred vision. After detailed anamnesis and clinical assessment, she was diagnosed as primary ITP in haematology department, and systemic steroid (1.5mg/kg) therapy was initiated. During her follow-up, a concomitant peripheral facial paralysis (PFP) emerged. In the course of follow-up, her platelet counts increased gradually, the retinal haemorrhages regressed partially, and the PFP recovered completely. CONCLUSION ITP is a rare haematologic disease that sometimes manifests with additional systemic involvements, and this disease should be remembered in the differential diagnosis of unusual retinal haemorrhages, which might be the only presenting feature.

Abstract
PURPOSE The purpose of this study was to compare the effects of reviparin, dalteparin and enoxaparin on intraoperative blood loss in patients with trochanteric fracture treated with intramedullary nailing. MATERIALS AND METHODS This retrospective multicenter study included 100 patients with trochanteric fracture who were divided into three groups according to the low-molecular-weight heparin administered. In all cases, a short third generation Gamma nail was used for osteosynthesis. Complete blood count and number of red blood cell transfusions (RBC) were evaluated. RESULTS The mean value of postoperative haemoglobin level was lower in the enoxaparin group compared to the reviparin group, with significant difference (p = 0.001; 95% CI 4.1-18.87). Patients in the dalteparin group received more RBC transfusions compared to the reviparin and enoxaparin group (p = 0.048). CONCLUSION The use of enoxaparin and dalteparin in hip fracture patients can result in lower postoperative haemoglobin levels and more RBC transfusions compared to reviparin.

Abstract
INTRODUCTION Angioembolisation (AE) and/or pre-peritoneal pelvic packing (PPP) may be necessary for patients with complex pelvic fractures who are haemodynamically unstable. However, it remains unclear whether AE or PPP should be performed as an initial intervention and ongoing debates exist. This meta-analysis aimed to compare AE versus PPP in haemodynamically unstable patients with acute pelvic fractures. The primary outcomes of interest were to compare in-hospital mortality rate and number of blood units transfused. Secondary outcomes included evaluating differences in the time from diagnosis to treatment, as well as the length of stay in the intensive care unit (ICU) and hospital. METHODS All clinically relevant studies comparing AE versus PPP in patients with complex pelvic fractures and haemodynamic instability were accessed. The 2020 PRISMA guidelines were followed. In September 2023, the following databases were accessed: PubMed, Web of Science, Google Scholar and Embase, without constraint. RESULTS Data from 320 patients were collected (AE: 174; PPP: 146). The mean age on admission was 47.4 ± 7.2 years. The mean Injury Severity Score (ISS) on admission was 43.5 + 5.4 points. Baseline comparability was observed in ISS (P = 0.5, Table 3) and mean age (P = 0.7, Table 3). No difference was reported in mortality rate (P = 0.2) or rate of blood units transfused (P = 0.3). AE had a longer mean time to the procedure of 44.6 min compared to PPP (P = 0.04). The mean length of ICU and hospital stay were similar in both groups. CONCLUSION Despite the longer mean time from admission to the procedure, no significant differences were found between AE and PPP in terms of in-hospital mortality, blood units transfused, or length of ICU, and hospital stay. These findings should be interpreted considering the limitations of the present study. High-quality comparative research is strongly warranted. LEVEL OF EVIDENCE Level IV, meta-analysis.

Abstract
Aim This study aimed to identify the key parameters to assist the early diagnosis of Dengue Infection to prevent severe outcomes. Methodology A cross-sectional study was conducted from June 2022 to December 2022 at a tertiary care hospital. 149 patients who presented with dengue symptoms for less than 5 days were enrolled in the study. Hepatic functioning was assessed by monitoring Serum Alanine Transaminase (ALT) (normal = 7-56 IU/L), and serum Aspartate Transaminase (AST) (normal = 10-40 IU/L) levels. Abdominal ultrasound and chest X-Ray were performed, and findings were recorded. Statistical analysis was done using SPSS Version 24. Results 81 patients (54.36%) were found to have Classical DF, while 46 patients (45.64%) were diagnosed with DHF or DSS. Dengue fever is more common in males than in females, and it disproportionately affects those under the age of 30. Only 81 (54.63%) of the total 149 individuals developed DF, but of those, 79 (74.4%) had normal ALT levels and 2 (4.26%) had elevated ALT levels. Among the 68 patients with DHF (45.64%), 41 (87.23%) had elevated ALT, while only 23 (22.55%) had normal ALT and all 4 (8.51%) with DSS did as well. The p-value for the correlation between platelet count and elevated ALT levels is 0.007, which is statistically significant. Conclusion Management of dengue disease requires close monitoring of hepatic enzyme levels, particularly ALT and AST, along with the platelet count. It will aid in reducing the severity of the dengue virus. In addition, there should be particular outdoor exposure guidelines, particularly during dengue season evenings, i.e., monsoon.

Abstract
OBJECTIVES To evaluate the efficacy of thermal welding (TW) versus cold dissection (CD) strategies among tonsillectomy patients. DESIGN AND SETTING A systematic review and meta-analysis of randomised controlled trials (RCTs). PARTICIPANTS Patients undergoing tonsillectomy. MAIN OUTCOME MEASURES The outcomes were summarised as risk ratio (RR) or mean difference/standardised mean difference (MD/SMD) with 95% confidence interval (CI) in a random-effects model. RESULTS Fourteen RCTs were analysed. The mean operative time (n = 14 RCTs, MD = -7.99 min, 95% CI [-12.88, -3.10], p < .001), mean intraoperative blood loss (n = 11 RCTs, MD = -57.18 mL, 95% CI [-71.58, -42.78], p < .001) and postoperative pain score on day 1 (n = 15 RCTs, SMD = -0.40, 95% CI [-0.75, -0.06], p = .02) were significantly reduced in the TW group compared with the CD group. However, there was no significant difference between both groups regarding the rate of reactionary bleeding (n = 13 RCTs, RR = 0.62, 95% CI [0.23, 1.71], p = .36) and delayed bleeding (n = 13 RCTs, RR = 1.03, 95% CI [0.46, 2.30], p = .95). CONCLUSION Compared with CD, TW significantly reduced the operative time and intraoperative blood loss, without an impact on the rate of postoperative bleeding. The reduction in postoperative pain score provided by the TW strategy was not clinically meaningful in clinical practice. TW might appear superior to CD among tonsillectomy patients.

Abstract
INTRODUCTION Gastrointestinal (GI) lipomas are rare; however, they are frequent enough to be considered in the differential diagnosis of gut tumours. Here, we present our experience with GI lipomas managed at our institute over the last three years. METHODS This is a retrospective cohort study of patients with GI lipomas managed between January, 2020 and April, 2023 at a tertiary care centre. Clinical presentation, location, and details of surgical procedure were analysed. RESULTS Ten patients were included, six of whom had lipoma in the colon, one in the stomach, and one each in the duodenum, jejunum, and ileum. The mean age at the time of presentation was 48.8 years (range, 19-77 years), and strong male preponderance (4:1) was noted. Preoperative diagnosis of lipoma on cross-sectional imaging was possible in all patients. All patients were symptomatic and were managed surgically. CONCLUSIONS While GI lipomas are generally considered to be indolent and benign tumours, they can potentially lead to severe complications. The utilisation of computed tomography and magnetic resonance imaging has brought about a significant transformation in diagnosing this condition, enabling preoperative identification in most cases. The surgery offers a definitive treatment with minimal risk of postoperative complications.

Abstract
OBJECTIVE To determine whether primary percutaneous coronary intervention (PPCI) is associated with adverse outcomes following coronary artery bypass graft (CABG) among patients with ST-elevation myocardial infarction (STEMI). METHODS Patients presenting with acute STEMI who underwent CABG between September 2015 and November 2020 were included. Among 354 patients, 222 (62.7%) underwent PPCI prior to CABG (PPCI+CABG group) and were compared with the rest of the patients (CABG only group). The effects of PPCI on primary endpoints---including in-hospital mortality, length of stay (LOS), and bleeding events---were investigated using the stabilised inverse probability weighting method (S-IPW). Further, in-hospital mortality in various PPCI subgroups was analysed using univariable regression. RESULTS Patients with and without PPCI were comparable regarding their baseline and surgical characteristics, except that those without PPCI were more likely to have left-main disease (29.5% vs 16.2%, p-value=0.003). Among the PPCI+CABG group, 3.6% mortality and 55.9% bleeding events occurred, and the LOS was 7 [5-10] days. The respective figures for the CABG only group were 4.5%, 50.8%, and 7 [6-10.5] days. Primary percutaneous coronary intervention, as a whole, was not significantly associated with either morality (S-IPW odds ratio (S-IPW OR) 0.61; p=0.393), LOS logarithm (S-IPW β -0.050; p=0.403), or bleeding events (S-IPW OR 1.06; p=0.821). Nevertheless, the unadjusted mortality risk was significantly higher in complicated PPCIs compared with the CABG only group (OR 7.50, 95% CI 2.03-27.77); it was also higher among some other PPCI subgroups, albeit non-significantly. CONCLUSION This study found that PPCI did not confer additional risk regarding in-hospital mortality, LOS, or bleeding among patients with acute STEMI who underwent CABG. However, some PPCI subgroups, especially those with complicated PPCI, were at increased risk.

Abstract
BACKGROUND High energy pelvic ring injuries are associated with significant morbidity and mortality and can be accompanied by haemorrhagic shock following associated vascular injury. This study evaluated the causes and predictors of mortality in haemodynamically unstable pelvic fractures. METHODS This retrospective observational study at a Major Trauma Centre reviewed 938 consecutive adult patients (≥ 18yrs) with pelvic ring injuries between December 2014 and November 2018. Patients with features of haemorrhagic shock were included, defined as: arrival Systolic BP < 90 mmHg, Base Deficit ≥ 6.0 mmol/l, or transfusion of ≥ 4 units of packed red blood cells within 24 h. RESULTS Of the 102 patients included, all sustained injuries from high energy trauma, and 47.1% underwent a haemorrhage control intervention (Resuscitative Endovascular Balloon Occlusion of the Aorta-REBOA, Interventional Radiology-IR, or Laparotomy). These were more often required following vertical shear injuries (OR 10.7, p = 0.036). Overall, 33 patients (32.4%) died; 16 due to a head injury, and only 2 directly from acute pelvic exsanguination (6.1%). Multivariable logistic regression demonstrated that increasing age, Injury Severity Score, Abbreviated Injury Scale (AIS) Head ≥ 3 and open pelvic fracture were all independent predictors of mortality, and IR was associated with reduced mortality. Lateral Compression III (LC3) injuries were associated with mortality due to multiple organ dysfunction syndrome (MODS). CONCLUSION Haemodynamically unstable patients with pelvic ring injuries have a high mortality rate, but death is usually attributed to other injuries or later complications, and not from acute exsanguination. This reflects improvements in resuscitative care, transfusion protocols, and haemorrhage control techniques.

Abstract
INTRODUCTION A difficult question in autopsy practice is whether intracranial haemorrhage has resulted from or brought about a fall. MATERIAL AND METHODS To address this we undertook a retrospective study of all autopsy reports (N = 2126) complied over a 10 year period (2009-2018). Of 720 patients who underwent a comprehensive post mortem neuropathologic examination we found 226 patients who had a history of a fall. RESULTS Of the 226 with a history of fall, 175 (79%) had an intracranial haemorrhage which was classified as truamatic (n = 134, 77%) or spontaneous (n = 41, 23%. Within the traumatic group, falls from a standing height (51%) were more common than falls involving stairs (31%) or falls from a height (12%). Cerebral contusional injury (51%) and subdural haemorrhage (45%) were the most common type of haemorrhage in the traumatic group. In the spontaneous haemorrhage group cerebral amyloid angiopathy (49%) was the commonest detected cause and was typically lobar in distribution). CONCLUSION We are of the view that a comprehensive analysis of fatal falls with intracranial haemorrhage warrants a detailed neuropathologic examination as part of the overall death analysis.

Abstract
OBJECTIVES To comprehensively evaluate the glioma using quantitative susceptibility mapping (QSM). MATERIALS AND METHODS Forty-two patients (18 women; mean age, 45 years) with pathologically confirmed gliomas were retrospectively included. All the patients underwent conventional and advanced MRI examinations (QSM, DWI, MRS, etc.). Five patients underwent paired QSM (pre- and post-enhancement). Four Visually Accessible Rembrandt Image (VASARI) features and intratumoural susceptibility signal (ITSS) were observed. Three ROIs each were manually drawn separately in the tumour parenchyma with relatively high and low magnetic susceptibility. The association between the tumour's magnetic susceptibility and other MRI parameters was also analysed. RESULTS Morphologically, gliomas with heterogeneous ITSS were more similar to high-grade gliomas (p = 0.006, AUC: 0.72, sensitivity: 70%, and specificity: 73%). Heterogeneous ITSS was significantly associated with tumour haemorrhage, necrosis, diffusion restriction, and avid enhancement but did not change between pre- and post-enhanced QSM. Quantitatively, tumour parenchyma magnetic susceptibility had limited value in grading gliomas and identifying IDH mutation status, whereas the relatively low magnetic susceptibility of the tumour parenchyma helped identify oligodendrogliomas in IDH mutated gliomas (AUC = 0.78) with high specificity (100%). The relatively high tumour magnetic susceptibility significantly increased after enhancement (p = 0.039). Additionally, we found that the magnetic susceptibility of the tumour parenchyma was significantly correlated with ADC (r = 0.61) and Cho/NAA (r = 0.40). CONCLUSIONS QSM is a promising candidate for the comprehensive evaluation of gliomas, except for IDH mutation status. The magnetic susceptibility of tumour parenchyma may be affected by tumour cell proliferation. KEY POINTS • Morphologically, gliomas with a heterogeneous intratumoural susceptibility signal (ITSS) are more similar to high-grade gliomas (p = 0.006; AUC, 0.72; sensitivity, 70%; and specificity, 73%). Heterogeneous ITSS was significantly associated with tumour haemorrhage, necrosis, diffusion restriction, and avid enhancement but did not change between pre- and post-enhanced QSM. • Tumour parenchyma's relatively low magnetic susceptibility helped identify oligodendroglioma with high specificity. • Tumour parenchyma magnetic susceptibility was significantly correlated with ADC (r = 0.61) and Cho/NAA (r = 0.40).

Abstract
BACKGROUND Haemorrhage is a common complication following open simple prostatectomy and patients may sometimes require a blood transfusion. Tranexamic acid has been shown to reduce blood loss following transurethral resection of the prostate and open radical prostatectomy. This study evaluated the effect of perioperative intravenous administration of tranexamic acid on blood loss and blood transfusion rates in patients who had OSP for benign prostatic enlargement. METHODOLOGY This was a comparative study of patients with documented prostate glands 60g and above scheduled for OSP. Initial hematocrit was done a day before surgery. The patients were randomized into a tranexamic acid group, which received perioperative intravenous tranexamic acid and the no-TXA group which received placebo (0.9% saline). All patients had open simple retropubic prostatectomy. Final post-operative hematocrit was assessed 72 hours after surgery, and blood loss was calculated using the modified Gross formula (actual blood loss = estimated blood volume x change in hematocrit / mean hematocrit). The transfusion rate was documented. RESULTS Fifty-six patients participated in this study and were randomized into a tranexamic acid group and no-tranexamic acid group. The mean age of patients in the tranexamic acid group was 66.07 ±7.08 years and was comparable to the no- tranexamic acid group which was 66.50 ± 8.80 years (P = 0.842). The median total blood loss was lower in the tranexamic acid group (502mls, IQR 613) compared to the no-tranexamic acid group (801mls, IQR 1069). The difference in the median blood loss between the two groups was 299mls (U 275, P 0.055). The rate of blood transfusion was lower in the tranexamic acid group (6 patients, 21%) compared to the no tranexamic acid group (11 patients, 39%), (P = 0.146). There was no difference in complication rates between the two groups. CONCLUSION The use of tranexamic acid in patients undergoing open simple prostatectomy showed a trend towards reduced intraoperative blood loss and less need no tranexamic for blood transfusion. This is of clinical significance, especially in elderly patients with low cardiovascular reserve.

Abstract
BACKGROUND Cerebral cavernous malformations (CCMs) frequently manifest with haemorrhages. Stereotactic radiosurgery (SRS) has been employed for CCM not suitable for resection. Its effect on reducing haemorrhage risk is still controversial. The aim of this study was to expand on the safety and efficacy of SRS for haemorrhagic CCM. METHODS This retrospective multicentric study included CCM with at least one haemorrhage treated with single-session SRS. The annual haemorrhagic rate (AHR) was calculated before and after SRS. Recurrent event analysis and Cox regression were used to evaluate factors associated with haemorrhage. Adverse radiation effects (AREs) and occurrence of new neurological deficits were recorded. RESULTS The study included 381 patients (median age: 37.5 years (Q1-Q3: 25.8-51.9) with 414 CCMs. The AHR from diagnosis to SRS excluding the first haemorrhage was 11.08 per 100 CCM-years and was reduced to 2.7 per 100 CCM-years after treatment. In recurrent event analysis, SRS, HR 0.27 (95% CI 0.17 to 0.44), p<0.0001 was associated with a decreased risk of haemorrhage, and the presence of developmental venous anomaly (DVA) with an increased risk, HR 1.60 (95% CI 1.07 to 2.40), p=0.022. The cumulative risk of first haemorrhage after SRS was 9.4% (95% CI 6% to 12.6%) at 5 years and 15.6% (95% CI% 9 to 21.8%) at 10 years. Margin doses> 13 Gy, HR 2.27 (95% CI 1.20 to 4.32), p=0.012 and the presence of DVA, HR 2.08 (95% CI 1.00 to 4.31), p=0.049 were factors associated with higher probability of post-SRS haemorrhage. Post-SRS haemorrhage was symptomatic in 22 out of 381 (5.8%) patients, presenting with transient (15/381) or permanent (7/381) neurological deficit. ARE occurred in 11.1% (46/414) CCM and was responsible for transient neurological deficit in 3.9% (15/381) of the patients and permanent deficit in 1.1% (4/381) of the patients. Margin doses >13 Gy and CCM volume >0.7 cc were associated with increased risk of ARE. CONCLUSION Single-session SRS for haemorrhagic CCM is associated with a decrease in haemorrhage rate. Margin doses ≤13 Gy seem advisable.

Abstract
BACKGROUND This study aimed to assess whether pregnancy and puerperium were associated with the risk of brain arteriovenous malformation (bAVM) haemorrhage. METHODS A retrospective review was conducted in Xiangya Hospital, Central South University from January 2012 to December 2021. A case-crossover design was adopted to calculate the incidence density of bAVM-related haemorrhage among female patients in risk (pregnancy and puerperium) and control (non-pregnancy and non-puerperium) periods, according to four scenarios observed in different populations (scenario I: patients with haemorrhagic bAVM of all ages; scenario II: patients with haemorrhagic bAVM of all ages, with at least one previous pregnancy; scenario III: patients with haemorrhagic bAVM who are of reproductive age (15-45 years); scenario IV: patients with haemorrhagic bAVM of reproductive age (15-45 years), with at least one previous pregnancy. Next, a comprehensive literature aggregation (up to April 2022) was performed for evidence synthesis. RESULTS Among the 311 female patients with haemorrhagic bAVM, a significant haemorrhage risk during pregnancy and puerperium was found in Scenarios I (relative risk [RR], 2.08; 95% CI, 1.28 to 3.39), II (RR, 3.21; 95% CI, 1.95 to 5.31) and IV (RR, 2.92; 95% CI, 1.73 to 4.93); however, a suggestive risk was found in scenario III (RR, 1.62; 95% CI, 0.99 to 2.67). Evidence synthesis revealed a consistent haemorrhage risk among patients of all ages (RR, 3.15; 95% CI, 1.93 to 5.15) and those of reproductive age (RR, 1.29; 95% CI, 0.89 to 1.86). CONCLUSION Compared with most previous studies, a higher but relatively moderate risk for bAVM-related haemorrhage was identified during pregnancy and puerperium. Individualised prevention and treatment strategies should be preferred when neurosurgeons make clinical decisions.

Abstract
INTRODUCTION AND IMPORTANCE OF THE CASE Aorto-oesophageal fistula (AEF) following foreign body ingestion is rare and conservative management is always fatal. The delayed presentation further confounds poor outcomes. PRESENTATION OF CASE A 46-year-old South-Asian woman presented with pain and difficulty in swallowing following ingestion of a mutton-containing meal. The patient refused urgent upper GI endoscopy and was initially managed conservatively on the basis of the resolution of symptoms and hemodynamic stability and was discharged home. On review a week later, the patient did not consent to a UGIE. She presented the next day with a severe upper GI bleed. Due to profuse haemorrhage, a bleeding point could not be identified, and she suffered a cardiac arrest. Attempts at resuscitation were unsuccessful. The autopsy revealed an AEF caused by a sharp mutton bone lodged in the lower oesophagus. CLINICAL DISCUSSION High-risk food bolus impactions such as the ones caused by sharp objects need urgent endoscopy to confirm the position and extraction if safe. AEF occurs with time and could result in massive haemorrhage and mediastinitis. Endoscopic stenting, thoracoscopic surgery, and open repair are methods of emergent and definite management that still carry significant mortality. CONCLUSION Management of AEF requires early diagnosis with a high index of suspicion, endoscopic and CT-based angiography studies, and surgical interventions tailored to patients based on the available expertise. High-risk patients should be similarly educated on the probable complications and the symptomatology.

Abstract
BACKGROUND Definitions for massive transfusion (MT) vary widely between studies, contributing to challenges in interpretation of research findings and practice evaluation. In this first systematic review, we aimed to identify all MT definitions used in randomised controlled trials (RCTs) to date to inform the development of consensus definitions for MT. METHODS We systematically searched the following databases for RCTs from inception until 11 August 2022: MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Cumulative Index to Nursing and Allied Health Literature, and Transfusion Evidence Library. Ongoing trials were sought from CENTRAL, ClinicalTrials.gov, and World Health Organisation International Clinical Trials Registry Platform. To be eligible for inclusion, studies had to fulfil all the following three criteria: (1) be an RCT; (2) include an adult patient population with major bleeding who had received, or were anticipated to receive, an MT in any clinical setting; and (3) specify a definition for MT as an inclusion criterion or outcome measure. RESULTS Of the 8,458 distinct references identified, 30 trials were included for analysis (19 published, 11 ongoing). Trauma was the most common clinical setting in published trials, while for ongoing trials, it was obstetrics. A total of 15 different definitions of MT were identified across published and ongoing trials, varying greatly in cut-offs for volume transfused and time period. Almost all definitions specified the number of red blood cells (RBCs) within a set time period, with none including plasma, platelets or other haemostatic agents that are part of contemporary transfusion resuscitation. For completed trials, the most commonly used definition was transfusion of ≥ 10 RBC units in 24 h (9/19, all in trauma), while for ongoing trials it was 3-5 RBC units (n = 7), with the timing for transfusion being poorly defined, or in some trials not provided at all (n = 5). CONCLUSIONS Transfusion of ≥ 10 RBC units within 24 h was the most commonly used definition in published RCTs, while lower RBC volumes are being used in ongoing RCTs. Any consensus definitions should reflect the need to incorporate different blood components/products for MT and agree on whether a 'one-size-fits-all' approach should be used across different clinical settings.

Abstract
AIM The management of patients who present with a post-tonsillectomy bleed (PTB) who are not actively haemorrhaging is contentious. In our institution, those without an active bleed are admitted for a period of observation, due to the theoretical risk of further bleeding. This paper aims to review PTB admissions to ascertain the risk of rebleeding while under observation and to identify whether there is a low-risk group who can be safely discharged without observation. METHODS Review of current literature. Retrospective chart review of all patients who presented to Perth Children's Hospital between February 2018 and February 2022 with a PTB. Exclusion criteria included primary PTB, known blood dyscrasias and patients >16 years of age. RESULTS A total of 826 presentations of secondary PTB (sPTB) were reviewed, with 752 admitted for a period of observation. Twenty-two (2.9%) patients rebled while under observation, with 17 managed operatively. The average age of patients who rebled was 6.2 years and they presented at an average 7.14 post-operative days. The median time to rebleed was 4.4 h. Four patients with no oropharyngeal clot at presentation subsequently re-bled (0.53%) while under observation, with 2 (0.26%) managed surgically. In patients observed with an oropharyngeal clot at presentation 18 (3.1%) rebled, with 15 (2.6%) managed operatively. CONCLUSION Patients presenting with a sPTB have a low risk of rebleeding while under observation. Patients with a normal oropharyngeal examination at presentation have a very low risk of rebleed and should be considered for early discharge if they meet other low risk criteria. Patients who present with an oropharyngeal clot can be safely observed with a low risk of further bleeding. Patients who rebleed while under observation should have a trial of conservative management if clinically appropriate.

Abstract
OBJECTIVES To describe the protocol for a multinational randomised, parallel, superiority trial, in which patients were randomised to receive early high-dose cryoprecipitate in addition to standard major haemorrhage protocol (MHP), or Standard MHP alone. BACKGROUND Blood transfusion support for trauma-related major bleeding includes red cells, plasma and platelets. The role of concentrated sources of fibrinogen is less clear and has not been evaluated in large clinical trials. Fibrinogen is a key pro-coagulant factor that is essential for stable clot formation. A pilot trial had demonstrated that it was feasible to deliver cryoprecipitate as a source of fibrinogen within 90 min of admission. METHODS Randomisation was via opaque sealed envelopes held securely in participating Emergency Departments or transfusion laboratories. Early cryoprecipitate, provided as 3 pools (equivalent to 15 single units of cryoprecipitate or 6 g fibrinogen supplementation), was transfused as rapidly as possible, and started within 90 min of admission. Participants in both arms received standard treatment defined in the receiving hospital MHP. The primary outcome measure was all-cause mortality at 28 days. Symptomatic thrombotic events including venous thromboembolism and arterial thrombotic events (myocardial infarction, stroke) were collected from randomisation up to day 28 or discharge from hospital. EQ5D-5Land Glasgow Outcome Score were completed at discharge and 6 months. All analyses will be performed on an intention to treat basis, with per protocol sensitivity analysis. RESULTS The trial opened for recruitment in June 2017 and the final patient completed follow-up in May 2022. DISCUSSION This trial will provide firmer evidence to evaluate the effectiveness and cost-effectiveness of early high-dose cryoprecipitate alongside the standard MHP in major traumatic haemorrhage.

Abstract
INTRODUCTION Open pelvic fractures are commonly associated with life-threatening, uncontrollable haemorrhages. Although management methods for pelvic injury-associated haemorrhage have been established, the early mortality rate associated with open pelvic fractures remains high. This study aimed to identify predictors of mortality and effective treatment methods for open pelvic fractures. METHODS We defined open pelvic fractures as pelvic fractures with an open wound directly connected to the adjacent soft tissue, genitals, perineum, or anorectal structures, resulting in soft tissue injuries. This study was performed on trauma patients (age ≥15 years) injured by a blunt mechanism between 2011 and 2021 at a single trauma centre. We collected and analysed the data on the Injury Severity Score (ISS), the Revised Trauma Score (RTS), the Trauma and Injury Severity Score (TRISS), length of hospital stay, length of intensive care unit stay, transfusion, preperitoneal pelvic packing (PPP), resuscitative endovascular balloon occlusion of the aorta (REBOA), therapeutic angio-embolisation, laparotomy, faecal diversion, and mortality. RESULTS Forty-seven patients with blunt open pelvic fractures were included. The median age was 45 years (interquartile range, 27-57 years) and median ISS was 34 (24-43). The most frequently performed treatment methods were laparotomy (53%) and pelvic binder (53%), followed by faecal diversion (40%) and PPP (38%). PPP was the only method performed at a higher rate in the survival group for haemorrhagic control (41% vs. 30%). Haemorrhagic mortality was present in one case that received PPP. The overall mortality was 21%. In the univariate logistic regression analysis, initial systolic blood pressure (SBP), TRISS, RTS, packed red blood cell transfusion for the first 24 h, and base excess showed statistical significance (p<0.05). In the multivariate logistic regression model, initial SBP was identified as an independent risk factor for mortality (odds ratio, 0.943; 95% confidence interval, 0.907-0.980; p = 0.003). CONCLUSION A low initial SPB may be an independent predictor of mortality in patients with open pelvic fractures. Our findings suggest that PPP might be a feasible method to decrease haemorrhagic mortality from open pelvic fractures, especially for haemodynamically unstable patients with low initial SBP. Further studies are required to validate these clinical findings.

Abstract
INTRODUCTION The occurrence of massive haemorrhages in various emergency situations increases the need for blood transfusions and increases the risk of mortality. Fibrinogen concentrate (FC) use may increase plasma fibrinogen levels more rapidly than fresh-frozen product or cryoprecipitate use. Previous several systematic reviews and meta-analyses have not effectively demonstrated FC efficacy in significantly improving the risk of mortality and reducing transfusion requirements. In this study, we investigated the use of FC for haemorrhages in emergency situations. METHODS AND ANALYSIS In this systematic review and meta-analysis, we included controlled trials, but excluded randomized controlled trials (RCTs) in elective surgeries. The study population consisted of patients with haemorrhages in emergency situations, and the intervention was emergency supplementation of FC. The control group was administered with ordinal transfusion or placebo. The primary and secondary outcomes were in-hospital mortality and the amount of transfusion and thrombotic events, respectively. The electronic databases searched included MEDLINE (PubMed), Web of Science, and the Cochrane Central Register of Controlled Trials. RESULTS Nine RCTs in the qualitative synthesis with a total of 701 patients were included. Results showed a slight increase in in-hospital mortality with FC treatment (RR 1.24, 95% CI 0.64-2.39, p = 0.52) with very low certainty of the evidence. There was no reduction in the use of red blood cells (RBC) transfusion in the first 24 h after admission with FC treatment (mean difference [MD] 0.0 Unit in the FC group, 95% CI - 0.99-0.98, p = 0.99) with very low certainty of the evidence. However, the use of fresh-frozen plasma (FFP) transfusion significantly increased in the first 24 h after admission with FC treatment (MD 2.61 Unit higher in the FC group, 95% CI 0.07-5.16, p = 0.04). The occurrence of thrombotic events did not significantly differ with FC treatment. CONCLUSIONS The present study indicates that the use of FC may result in a slight increase in in-hospital mortality. While FC did not appear to reduce the use of RBC transfusion, it likely increased the use of FFP transfusion and may result in a large increase in platelet concentrate transfusion. However, the results should be interpreted cautiously due to the unbalanced severity in the patient population, high heterogeneity, and risk of bias.

Abstract
The public enquiry into the mass casualty incident at the Manchester Arena in the UK in which 23 people died and over 1000 were injured, identified the need for timely intramuscular administration of tranexamic acid to trauma patients. Since then, a number of studies and trials have been carried out and UK paramedics are now authorized to give intramuscular tranexamic acid in the pre-hospital setting. In Japan, pre-hospital administration by emergency life-saving technicians is not yet authorized, despite the fact that tranexamic acid was invented by Japanese scientists. In Japan, the need for the pre-hospital administration of tranexamic acid has been raised on several occasions, where a patient died from traumatic bleeding prior to hospital admission. This paper summarizes the evidence on the use of tranexamic acid in patients with traumatic bleeding, including new evidence on the intramuscular route.

Abstract
OBJECTIVE In this paper we interpret a pathology observed in an early medieval horse skull discovered near the abutment of the eastern Gniezno bridge in Ostrów Lednicki in Poland. We consider the possible cause of the observed damage in the context of the armed invasion of the Czech prince Brzetysław and a battle of Ostrów Lednicki. MATERIALS A skull of a 10-year-old male horse dated to the 11th century. METHODS The skull was examined macroscopically and through computed tomography. Metric analysis was performed using digital callipers and the shoulder height was calculated. RESULTS A penetrating lesion through the left frontal and nasal bones was observed. The floor and roof of the left conchofrontal sinus were destroyed along with the dorsal ethmoturbinates of the ethmoid labyrinth. CONCLUSIONS The observed damage was most likely a result of trauma, which caused a fatal haemorrhage rather than sudden death. Considering the historical context and the area where the skull was discovered, it could be a battle wound. SIGNIFICANCE This case is a rare example of an unhealed peri-mortem lesion in an animal skeleton that can be associated with an immediate cause of death. LIMITATIONS The lack of a complete skeleton does not allow a complete analysis of horse's condition and circumstances associated with its death. SUGGESTIONS FOR FURTHER RESEARCH Identification of the tool or weapon that was used to deliver the blow.

Abstract
Von Willebrand disease (VWD) is an inherited bleeding disorder caused by quantitative or qualitative deficiencies in von Willebrand factor (VWF). People with VWD may experience excessive, recurrent or prolonged bleeding, particularly during menstruation, childbirth, surgery or following trauma. However, many VWD patients are undiagnosed, and therefore inadequately treated. Reasons for the underdiagnosis of VWD include its relatively mild symptoms, complex diagnosis, lack of awareness among non-specialist healthcare providers and the general population, and a lack of prioritisation of disorders disproportionately affecting females. The vwdtest.com platform was launched as part of a global initiative to raise awareness and improve diagnosis of VWD. Besides providing VWD-specific educational resources, the website includes an online bleeding self-assessment tool and offers diagnostic support for individuals, and their providers, who have a score suggestive of a bleeding disorder. vwdtest.com helps to address these unmet needs, especially in regions with limited access to educational and diagnostic resources.

Abstract
Background Corona Mortise is the name given to the anastomotic vessels forming a communication between external and internal iliac vascular systems. These channels have a high tendency to cause uncontrollable bleeding if injured and are particularly at risk during the anterior approach to acetabulum. While previous studies have described them as arterial or venous connections or both, there is still a lack of consensus regarding exact nature and location of these vessels, which make their timely identification all the more challenging. Objective The present review is aimed at performing a comprehensive review of existing literature and discuss the anatomy and implications of correct identification of Corona Mortise in pelvic-acetabular surgery. Conclusion Corona Mortise is more commonly venous than arterial. This not only makes haemorrhage control more challenging but also precludes the use of pre-operative angiography. However, most authors do not recommend a change in surgical approach for fear of damaging these vessels.

Abstract
INTRODUCTION A large number of patients under oral anticoagulant (OAC) or antiplatelet (AP) therapy require dental implantation. We systematically reviewed evidence on the risk of bleeding after implant placement with continued OAC or AP therapy. METHODS PubMed, Embase and CENTRAL were searched for studies comparing bleeding outcomes after implant placement between OAC/AP therapy vs. controls or OAC vs. AP therapy. RESULTS Seven studies were included. Pooled analysis showed no significant difference in the risk of bleeding with continued OAC therapy vs. control (RR 1.81 95% confidence interval [CI] 0.70, 4.63 I2 = 14% p = .22). Subgroup analysis depending on the type of OAC showed there was a non-significant tendency of increased risk of bleeding with Vitamin K antagonists (VKAs) (RR 3.42 95% CI 1.00, 11.67 I2 = 23% p = .05) but not with direct oral anticoagulants (DOACs) (RR 1.67 95% CI 0.49, 5.70 I2 = 0% p = .41). Limited data suggest an increased risk of bleeding with OAC as compared to AP (RR 0.08 95% CI 0.01, 0.76 I2 = 0% p = .03). CONCLUSIONS Continuation of OAC therapy in patients undergoing implant surgery does not increase the risk of bleeding provided local haemostatic measures are used. The indirect comparison suggests bleeding tendency may be higher with VKAs as compared to DOAC.

Abstract
All paediatric tonsillectomies were examined from 2012 – 2019 at a single tertiary-referral institution, and all were performed by one of two paediatric otolaryngologists. One exclusively used the diathermy, the other exclusively used the Coblator II. Two Coblator units were purchased simultaneously in 2012 and not replaced. There was no significant difference in number of tonsillectomies performed (1298 via diathermy, 1221 via Coblator), nor in postoperative day of bleed, patient age, indication for procedure, and no patient had an underlying coagulopathy. The most common indication for tonsillectomy in both groups was sleep-disordered breathing. There was no significant difference in postoperative haemorrhage rates between groups for the first six years of the study (0%-1.4%/year). Years 7 and 8 saw the Coblator group haemorrhage rate significantly increase (0%-0.6% diathermy group vs 2%-3% Coblator group), though still fell within accepted rate of postoperative haemorrhage. The devices were then replaced, and the differences in haemorrhage disappeared. There appears to be a significant increase in paediatric post-tonsillectomy haemorrhage when using a Coblator device greater than six years old. This may suggest a useful lifespan for the Coblator II device.

Abstract
BACKGROUND Diabetic Retinopathy (DR) is a serious consequence of diabetes that can result to permanent vision loss for a person. Diabetes-related vision impairment can be significantly avoided with timely screening and treatment in its initial phase. The earliest and the most noticeable indications on the surface of the retina are micro-aneurysm and haemorrhage, which appear as dark patches. Therefore, the automatic detection of retinopathy begins with the identification of all these dark lesions. METHOD In our study, we have developed a clinical knowledge based segmentation built on Early Treatment DR Study (ETDRS). ETDRS is a gold standard for identifying all red lesions using adaptive-thresholding approach followed by different pre-processing steps. The lesions are classified using super-learning approach to improve multi-class detection accuracy. Ensemble based super-learning approach finds optimal weights of base learners by minimizing the cross validated risk-function and it pledges the improved performance compared to base-learners predictions. For multi-class classification, a well informative feature-set based on colour, intensity, shape, size and texture, is developed. In this work, we have handled the data imbalance problem and compared the final accuracy with different synthetic data creation ratios. RESULT The suggested approach uses publicly available resources to perform quantitative assessments at lesions-level. The overall accuracy of red lesion segregation is 93.5%, which has increased to 97.88% when data imbalance problem is taken care-off. CONCLUSION The results of our system have achieved competitive performance compared with other modern approaches and handling of data imbalance further increases the performance of it.

Abstract
Cerebral cavernous malformations (CCMs) are commonly diagnosed, with a low reported rate of haemorrhage on long-term follow-up. The identification of factors predictive of future haemorrhage risk would assist in guiding the management of patients with CCM. The aim of this study was to identify variables associated with haemorrhage, and calculate haemorrhage risk in CCM. We conducted a retrospective study of patients diagnosed with a CCM, managed at a specialist tertiary neuroscience centre (2007-2019). The primary outcome was symptomatic haemorrhage, and secondary outcomes were variables associated with increased risk of haemorrhage, using multivariable Cox regression analysis. Included were 545 patients, with 734 confirmed cavernomas. Median age at diagnosis was 47 (interquartile range [IQR] 35-60), with a median follow-up duration after diagnosis of 46 months (IQR 19-85). Of the patients, 15.0% had multiple lesions (N = 82/545). Symptomatic presentation was observed in 52.5% of patients (N = 286/545). The annual haemorrhage rate was 1.00% per lesion-year (25 events in 2512 lesion-years), and higher in those with symptoms at presentation (1.50% per lesion-year, 22 events vs 0.29%, 3 events, P < 0.001). The variables associated with symptomatic haemorrhage were increased size (hazard ratio [HR] 1.04, 95% confidence interval [CI] 1.01-1.07, P = 0.004), eloquent location (HR 2.63, 95% CI 1.12-6.16, P = 0.026), and symptomatic haemorrhage at presentation (HR 5.37, 95% CI 2.40-11.99, P < 0.001). This study demonstrated that CCMs have a low haemorrhage rate. Increased size, eloquent location, and haemorrhage at presentation appear to be predictive of a higher risk of haemorrhage, and could be used to stratify management protocols.

Abstract
In the present research pathology and molecular diagnosis of elephant endotheliotropic herpes virus-haemorrhagic disease (EEHV-HD) among Asian elephants was studied. Out of 76 cases, 20 were positive for EEHV infection in PANPOL and POL1 based semi-nested PCR. Out of 20 samples, 10 samples were fatal cases of EEHV-HD while 10 were of either subclinical or latent infection. Acute onset haemorrhagic disease with EEHV-HD had anorexia, facial and neck swelling, cyanotic buccal mucosa and tongue, nasal and ocular discharge, and colic. The hallmark of gross finding in all cases were severe haemorrhagic lesions in the internal organs viz. cyanosis of tongue with multifocal petechial haemorrhages, diffuse epicardial and endocardial haemorrhages, swollen liver (rounded edges) with parenchymal haemorrhages, serosal and mucosal haemorrhages in gastrointestinal tract, congested kidneys with corticomedullary haemorrhages, highly congested meninges, and brain capillaries with haemorrhages. Microscopic findings in all the cases had severe vascular changes in the visceral organs. Microthrombi was present in the vasculature of tongue, heart, lung, liver, kidney, and brain. The endothelial lining of most of the blood vessels were swollen with apoptotic changes. Amphophilic to basophilic intranuclear inclusion bodies were observed in the endothelial cells. Immunostaining using anti-EEHV DNAPOL hyperimmune sera revealed intense positive signals in the endothelium of blood vessels and their walls. Quantification of viral load in necropsy tissue samples revealed highest in the heart (7.4 × 106/μg of sample) and least in the brain (9 × 103/μg of sample). The PCR amplicons from EEHV1 specific genes (POL1(U38) and TER were subjected to partial genome sequencing which had 99.9% similarity with the EEHV1A subtype. It was concluded that Asian elephants in India are latently infected for EEHV1 and in all the fatal EEHV-HD cases, EEHV1A subtype was the causative agent with characteristic pathomorphological changes in visceral organs.

Abstract
INTRODUCTION Haemorrhagic soft-tissue sarcomas (HSTS) are characterised by aggressive local growth and highly metastatic behaviour. We aimed to describe oncological outcomes and prognostic factors. MATERIALS AND METHODS Retrospective review including 64 patients treated with palliation (n = 7), with limb salvage surgery (LSS) (n = 9), with neoadjuvant radiotherapy (RT) + LSS (n = 12), with LSS + adjuvant RT (n = 30) or amputation (n = 6). Kaplan-Meier survival analysis estimated overall survival (OS), metastasis-free survival (MFS) and local recurrence-free survival (LRFS). After uni- and multivariate analysis, prognostic factors affecting OS, MFS and LRFS were identified. RESULTS Median age was 67 years (IQR 23 years) with median follow-up of 11 months (IQR 28 months). All cases were high grade. Eight (13%) had pulmonary metastases at presentation and another 40 (63%) developed metastases after median 9 months (IQR 19 months). Median OS was 12 months (IQR 38 months), and estimated OS after two-years was 15.9% and 52.9% for patients with and without metastatic disease at presentation, respectively. Improved OS was associated with negative resection margins (p = 0.031), RT (p = 0.045), neoadjuvant RT (versus adjuvant RT, p = 0.044) and amputation (versus LSS, p < 0.001). MFS was 35.1% after two-years. LR occurred in 18 of 51 (35.3%) patients with surgically treated localised disease. LRFS was 63.4% after two-years and significantly affected by a negative margin (p = 0.042) and RT (p = 0.001). CONCLUSION Haemorrhagic soft-tissue sarcomas should be excised, either with amputation or LSS with a clear resection margin. If LSS is attempted, neoadjuvant RT reduces the risk of tumour spillage and early LR, enhances the feasibility of achieving clear resection margins, and offers superior overall survival compared to adjuvant RT.
