Abstract
PURPOSE/OBJECTIVE(S) We routinely deliver Stereotactic Body Radiotherapy (SBRT) in malignant liver tumors using planning computed tomography (CT) and Magnetic Resonance Images (MRI) to aid target definition. In this study, we extracted radiomic features from the MR images to predict local control (LC) post-SBRT. MATERIALS/METHODS We retrospectively analyzed patients with either hepatocellular cancers (HCCs) or liver metastases (Mets) treated with SBRT between Aug 2014 and Aug 2020. All patients had CT simulation followed by 1.5 Tesla planning MRI in treatment position. Contrast enhanced T1 VIBE and T2 Haste MR sequences were registered with planning CT for target definition. Radiomic features were extracted from Gross Tumor Volumes (GTV) masked out of 60 seconds post contrast T1 VIBE MR images using the Radiomics calculator tool RaCaT. The output included 480 (408 textural, 50 intensity and 22 morphological) features for each target. Principal Component Analysis of the outputs obtained from all the targets yielded 20 radiomic feature clusters after computational prioritization. These clusters were correlated to LC outcomes at various time points post-SBRT. LC was defined as non-progressive disease. Accuracy of predictions was measured by area under (AUC) receiver operating characteristic curve. Cox regression analysis was done to find univariate and multivariate clinical [HCCs vs. Mets, single vs. multiple lesions, previous local therapy (yes vs. no), GTV volume (≤40 vs. >40 cc)], radiomic and dosimetric predictors (continuous) of LC. RESULTS In total, 97 patients received SBRT to 122 lesions. The median dose prescribed was 45 Gy (range, 30-50 Gy). Median age was 69 years (interquartile range, IQR 61-73 yrs.). 59 patients had HCCs and 38 had Mets. 24 lesions had prior ablative therapy. 75 patients had one target, and 22 had multiple targets. Median GTV was 43.5 cc (IQR 23.4-78.6 cc). Median follow up was 16.6 months (IQR 9.7-27.2 mths). Median LC was 13.6 months (IQR 8.0-23.5 mths). On univariate analysis, histology (HCCs vs. Mets; Hazard ratio (HR) 2.9, 95% CI 1.4-6.4; p < 0.006), radiomic clusters (p < 0.006) and the max., mean, and min. doses to GTV and Planning Target Volumes correlated with improved LC (all p-values < 0.05). On multivariate analysis, histology (HCCs vs. Mets; HR 4.4, 95% CI 1.6-12.3; p = 0.004), radiomic clusters (p = 0.034) and prescription dose (p = 0.048) were significant covariates. Specifically, the 20 radiomic clusters were predictive of LC, and the accuracy of predictions showed promise with AUC values of 0.74, 0.80, and 0.81 at 12, 24, and 36 months post-SBRT, respectively. AUC values for LC in HCCs vs. Mets at 12, 24, and 36 months were 0.83, 0.77, and 0.70, and 0.66, 0.77, and 0.88, respectively. CONCLUSION MR-based radiomics predict LC post-SBRT in patients with malignant liver tumors. Further research focused on independent validation of the model is required to explore its clinical use.

Abstract
INTRODUCTION Numerous studies have deemed the virtual fracture clinic (VFC) model to be both cost and clinically effective. However, very few of these studies have analysed the type of injuries seen in the VFC. The objectives of this study were to assess the clinical effectiveness of the VFC and analyse the types of injuries that lead to patients re-presenting in the face-to-face fracture clinic after being discharged virtually. METHODS This is a retrospective study analysing 17,269 patients referred to the VFC between September 2017 and February 2020. Data regarding the type of presenting injury were collected to understand which injuries required further management after being discharged virtually. Patient clinic letters provided data regarding the purpose and outcomes of VFC referrals as well as face-to-face appointments. Theatre lists were cross-referenced to extract data regarding surgical management. RESULTS In total, 57.37% (9,908) patients were discharged virtually. Of these patients, 92.52% were discharged successfully and 7.48% re-presented to the fracture clinic: 98.11% were managed conservatively and 1.88% required surgery. The highest number of failed discharges were for distal radius fractures (109, 14.69%). Face-to-face follow-up in fracture clinic was requested for 37.06% (6,400) of patients; 4.98% of them required surgical intervention. Some 5.56% (961) of referrals were removed from our analysis: 807 were inappropriate referrals and 154 were deemed suitable for multidisciplinary team discussion. The trust has saved an average of £702,205 annually since introduction of the VFC. CONCLUSIONS The VFC model delivers as promised in terms of clinical efficacy and cost management. Injury types showing higher numbers of unsuccessful discharges could benefit from having modified management pathways.

Abstract
Abstract
Introduction/Objective
Calcium pyrophosphate dihydrate (CPPD) crystal deposition or pseudogout is a common entity encountered in routine practice. However, when a common entity presents in uncommon locations with unusual clinical manifestations, it creates a diagnostic conundrum. Pseudogout commonly occurs in the joint extremities including knee, wrist, shoulder, hip, and ankle joints. The sternoclavicular joint is a rare site for pseudogout with very low incidence. To the best of our knowledge, there are only two other cases of pseudogout mimicking a tumor causing vascular obstruction in the literature.
Methods/Case Report
A 63 year old male presented with an enlarging supraclavicular mass. A computed tomography angiography scan of the chest revealed an irregular soft tissue mass located behind the medial clavicle measuring up to 4 cm and was noted to compress and partially occlude the right subclavian vein. Partial occlusion of right axillary vein, right internal jugular vein, and right brachiocephalic vein were also noted on imaging. The venous compression led to outflow obstruction and resultant recurrent deep vein thrombosis of the right upper extremity. Due to compression by the mass, he required stenting of the right subclavian vein which unfortunately reoccluded. Subsequently, the patient underwent excision of the mass and partial resection of the first rib with decompression of the thoracic outlet. The excisional biopsy revealed dense rhomboid-shaped CPPD crystal depositions in irregular nodules within a background of fibrinoid material and fragments of unremarkable cartilaginous tissue. The patients compressive symptoms were relieved following the excision. While clinically and radiologically the mass was concerning for a malignant tumor, histological examination provided a definitive diagnosis of a benign process.
Results (if a Case Study enter NA)
NA.
Conclusion
Pseudogout is a rare mimicker of bone and soft tissue tumors and differentiation from an enchondroma, or grade 1 chondrosarcoma becomes a challenge especially on small tissue biopsies and is a possible diagnostic pitfall.

Abstract
Abstract
Introduction
Penetrating brain injuries (PBI) are less common than closed head traumas. Interest in frontal lobe injuries dates back to 1848’s famous Phineas Gage incident. Here, we report a case of a construction worker, who showed a remarkable neuropsychiatric outcome following a workplace accident.
Case Presentation
45year old gentleman came with complaint of a foreign body accidentally lodged in his forehead. He had no neurological deficits or CSF leak. X-ray revealed that a 5.5cm metallic screw was penetrating his skull, headfirst; CT revealed that approximately 3cm of the screw was in the frontal sinus. He was given antiepileptics and antibiotics prophylactically. Surgically the screw was removed by raising a bone flap and mobilizing the screw carefully by cutting the dura and adequate irrigation, causing minimal damage to the brain parenchyma. The dural deficits were repaired and the frontal sinus was canalized, then a drain was placed, and the patient was shifted to ICU for postoperative monitoring.
Discussion
It is important to prognosticate PBI as they can have neurological deficits that may be lifelong. Understanding the mechanism of injury, aggressive medical management and immediate surgical intervention may lead to improved outcomes. A foreign object of the size of 5.5cm, completely penetrating the skull would have otherwise resulted in extensive parenchymal damage. Literature suggests that no two people have an identical frontal sinus. In our patient the size the frontal sinus has served the purpose of protection against PBI and has resulted in minimal parenchymal injury (of only about 1cm).

Abstract
BACKGROUND Surgical advanced clinical practitioners (SACPs) form part of the extended surgical workforce drawn from a variety of allied healthcare backgrounds. The primary aim of this study was to determine whether there was a financial benefit in having minor surgical procedures undertaken by dedicated SACPs compared with operating lists assigned to consultant surgeons. METHODS This was a retrospective cohort study including all patients who had minor 'lumps and bumps' procedures undertaken between April 2014 and August 2019 at East Lancashire Hospitals NHS Trust under local anaesthetic by the general surgery team. Clinical patient information, including lesion type, was collected along with operating room staffing levels and duration of operation. The cost of the procedure was calculated as operating time multiplied by cost of staff per minute according to local banding. RESULTS A total of 1399 patients had a lesion excised; 907 procedures were carried out by a doctor, and the rest independently by a SACP. The majority of lesions excised were lipomas and cysts. There was no difference in the median surgical time taken between SACPs and doctors (20 (i.q.r. 14-28) min). Minor procedures carried out on consultant surgeon lists cost 62.3 per cent (€25.33) more on average than those on SACP lists (median €65.96 versus 40.63 respectively; P < 0.001). CONCLUSION A dedicated and independent SACP 'lumps and bumps' list was financially beneficial. Operating times were similar to those of doctors. These lists safely free trainee and consultant surgeons to undertake more complex work.

Abstract
BACKGROUND Acute cutaneous graft-versus-host disease (acGVHD) following haematopoietic stem cell transplant (HSCT) is common but difficult to distinguish from other causes of rash. Plasma elafin has been proposed as a diagnostic and prognostic biomarker of skin GVHD. AIM To evaluate the role of plasma elafin as a biomarker in acGVHD in an Indian population. METHODS Plasma elafin was evaluated in a prospective study of HSCT recipients, conducted over 2 years, taking measurements at baseline and at onset of skin rash after HSCT. Patients were categorized into those with GVHD rash, those with non-GVHD rash and those with no rash and the three groups were compared. RESULTS Two hundred and sixty-one patients with a median age of 16 years (range 1-61 years) and a male predominance (175 : 86 M/F) underwent HSCT during the study period: 56 patients in the GVHD group, 49 in the non-GVHD group and 156 in the no-rash group. The median baseline elafin was similar in all three groups. At the onset of rash, median elafin level was similar between GVHD and non-GVHD rash (34 549 vs. 32 077 pg/mL; P = 0.58) and between GVHD and no rash (34 549 vs. 26 197 pg/mL; P = 0.08). A rise in elafin from baseline was significantly different between GVHD and no rash (P < 0.001) but not between GVHD and non-GVHD rash (P = 0.44). CONCLUSION The utility of plasma elafin as a biomarker of skin GVHD is very limited. Plasma elafin, although elevated in cutaneous GVHD, is not helpful in distinguishing between GVHD rash and other causes of rash following HSCT.

Abstract
Advances in perinatal medicine, present increasing numbers of women with difficult decisions about their pregnancy. We explored the views of 5 parents and 5 perinatal healthcare professionals regarding late termination of pregnancy following the principles of qualitative content analysis. Parents deciding on whether to (dis)continue pregnancy needed more time and decisional support. Decentralized care and lacking continuity between caregivers led to negative experiences. No standardized bereavement services were offered after leaving the hospital. Integrating principles of perinatal palliative care to care might help to offer further decisional support and to overcome the fragmentation of care.

Abstract
Background Cardiopulmonary exercise-testing (CPET) and the (Portsmouth) Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity ((P)-POSSUM) are used as pre-operative risk stratification and audit tools in general surgery, however, both have been demonstrated to have limitations in major hepatopancreatobiliary (HPB) surgery. Materials and methods The aim of this review is to determine if CPET and (P)-POSSUM scoring systems accurately predict morbidity and mortality. Eligible articles were identified with an electronic database search. Analysis according to surgery type and tool used was performed. Results Twenty-five studies were included in the final review. POSSUM predicted morbidity demonstrated weighted O/E ratios of 0.75(95%CI0.57–0.97) in hepatic surgery and 0.85(95%CI0.8–0.9) in pancreatic surgery. P-POSSUM predicted mortality in pancreatic surgery demonstrated an O/E ratio of 0.75(95%CI0.27–2.13) and 0.94(95%CI0.57–1.55) in hepatic surgery. In both pancreatic and hepatic surgery an anaerobic threshold(AT) of between 9 0.5–11.5 ml/kg/min was predictive of post-operative complications, and in pancreatic surgery ventilatory equivalence of carbon dioxide(˙VE/˙VCO2) was predictive of 30-day mortality. Conclusion POSSUM demonstrates an overall lack of predictive fit for morbidity, whilst CPET variables provide some predictive power for post-operative outcomes. Development of a new HPB specific risk prediction tool would be beneficial; the combination of parameters from POSSUM and CPET, alongside HPB specific markers could overcome current limitations. Current pre-operative scoring for pancreatic and liver surgery is inaccurate. In pancreatic and liver surgery anaerobic threshold scores were predictive of complications. In pancreatic surgery ventilatory equivalence of carbon dioxide was predictive of mortality. P-POSSUM is inaccurate for predicting mortality and morbidity in pancreatic surgery.

Abstract
Casestudy
Intraductal papillary neoplasm of the bile duct (IPNB) is a variant of bile duct carcinoma that is characterized by intraductal growth and better outcomes compared with common cholangiocarcinoma. IPNBs are mainly found in patients from Far Eastern countries, where hepatolithiasis and clonorchiasis are endemic.
Approximately 40%-80% of IPNBs are associated with invasive carcinoma. The invasive carcinomas are most often tubular or mucinous type. Invasive neuroendocrine component has not been previously described.
We present a case of 69 year-old African American male who presented with worsening abdominal pain and jaundice over few months. Computed tomography showed 4 cm mass near the porta hepatis with massive ductal dilatation. A fine needle aspiration of the mass was performed and a diagnosis of adenocarcinoma was made. Subsequently, the patient underwent Right Trisegmentectomy.
Conclusion
Histologic sections revealed intraductal papillary neoplasm in the bile duct lumina. The papillae were lined by columnar epithelial cells with delicate fibrovascular cores. The tumor cell nuclei were slightly elongated, hyperchromatic and basally located without significant multilayering. The cytoplasm was eosinophilic with occasional intestinal differentiation. Frank invasion of the stalk and underlying periductular tissues was identified. Interestingly; the invasive component had different cytological features than the intraductal component, it was composed of small to medium sized cells with granular cytoplasm. The nuclei were uniform and round with “salt and pepper” chromatin. The invasive component stained positively for the neuroendocrine markers (Synaptophysin, Chromogranin and CD56), whereas the intraductal component stained positively for CK7, CK20 and CDX2 and negative for neuroendocrine markers.
Three years later, a recurrent tumor was found in the left lobe on imaging. Biopsy of the lesion showed metastatic neuroendocrine carcinoma. The intraductal papillary neoplasm with invasive neuroendocrine component is very unusual tumor, we think more studies are warranted to best evaluate the treatment options and the prognosis of such neoplasms.

Abstract
Histamine or scombrotoxin fish poisoning is caused by ingestion of bacterially produced histamine in fish. Histamine-producing bacteria generally contain the histidine decarboxylase gene (hdc). However, some strains of Photobacterium phosphoreum are known to produce significant levels of histamine, although the hdc gene in these strains has not been recognized. The objective of this study was to investigate a previously unidentified mechanism of histamine production by P. phosphoreum. We identified a protein with histidine decarboxylase (HDC) activity comparable to activity of the pyridoxal-5-phosphate (PLP) dependent HDC from P. kishitanii and M. morganii. The newly identified protein (HDC2) in P. phosphoreum and P. kishitanii strains, was approximately 2× longer than the HDC protein from other Gram-negative bacteria and had 12% similarity to previously identified HDCs. In addition, the hdc2 gene cluster in P. phosphoreum was identical to the hdc gene cluster in P. kishitanii. HDC2 had optimal activity at 20-35 °C, at pH 4, and was not affected by 0-8% NaCl concentrations. Compared to the hdc gene from P. kishitanii, expression of the hdc2 gene was constitutive and not affected by pH or excess histidine. This newly identified protein explains possible mechanisms of histamine production in P. phosphoreum. Characterization of this protein will help in designing control measures to prevent or reduce histamine production in fish.

Abstract
As people age, they accumulate medical conditions. Geriatric giants comprise a group of conditions that lead to significant mortality and morbidity and contribute to the complexity in treating geriatric patients. They are common and rarely occur in isolation. The 5 Is of geriatric giants are: iatrogenesis, immobility, instability, incontinence and impaired cognition. Consequences for the patient and their caregivers include loss of functional independence, institutionalisation and caregiver burnout. Primary care practitioners are often the first port of call for geriatric patients in South Africa and by asking a few key questions and performing a thorough examination; these conditions can be recognised early. Whilst there are often limitations to cure, the main aim is to maintain the older adult’s functional independence as much as possible, and by following an organised management approach to each of these conditions, the quality of life of patients can be improved.

Abstract
Vaccines are considered the bedrock of preventive medicine. However, for many pathogens, it has been challenging to develop vaccines that stimulate protective, long-lasting immunity. We have developed a novel approach using β-1,3-D-glucans (BGs), natural polysaccharides abundantly present in fungal cell walls, as a biomaterial platform for vaccine delivery. BGs simultaneously provide for receptor-targeted antigen delivery to specialized antigen-presenting cells together with adjuvant properties to stimulate antigen-specific and trained non-specific immune responses. This review focuses on various approaches of using BG particles (GPs) to develop bacterial and fungal vaccine candidates. A special case history for the development of an effective GP tularaemia vaccine candidate is highlighted.

Abstract
BACKGROUND AND PURPOSE Stress is a known risk factor for the onset and modulation of disease activity in autoimmune disorders. The aim of this cross-sectional study was to determine any associations between myasthenia gravis (MG) severity and chronic stress, depression and personality type. METHODS In all, 179 consecutive adult patients with confirmed MG attending the Neuromuscular Clinic between March 2017 and December 2017 were included. At baseline, patients were assessed clinically and they completed self-administered scales for disease severity, perceived stress, depression and personality type. RESULTS Higher disease severity [Myasthenia Gravis Impairment Index (MGII)] showed a moderate correlation with depression score (Beck's Depression Inventory, Second Edition, r = 0.52, P < 0.001) and a lower correlation with chronic stress (Trier Inventory for Assessment of Chronic Stress, r = 0.28, P = 0.001). Chronic stress scores were different according to personality types (anova, P = 0.02). The linear regression model with MGII score as the dependent variable showed R2 = 0.34, likelihood ratio chi-squared 74.55, with P < 0.0001. The only variables that predicted disease severity were depression scores (P < 0.0001) and female sex (P = 0.003). CONCLUSIONS A significant association of MG severity with depression and chronic stress was found, as well as with female gender. These findings should raise awareness that the long-term management of MG should address depression and potential stress and consider behavioural management to prevent stress-related immune imbalance.

Abstract
BACKGROUND The use of home parenteral nutrition (HPN) for palliative indications is increasing internationally and is the leading indication in some countries. Discharge on HPN can be complex in metabolically unstable patients and requires intestinal failure expertise. METHODS Between 2012 and 2018, we performed a retrospective analysis aiming to assess the impact of a novel remote discharge pathway for palliative HPN patients. This was evaluated using a quality improvement approach. RESULTS One hundred and twenty-five patients with active malignancy [mean (range) age 58 (25-80) years] were referred to the intestinal failure unit (IFU) for remote discharge. Of 82 patients were discharged from the oncology Centre on HPN using the pathway. The remaining 43 patients either declined HPN or the Oncology team felt that the patient became too unwell for HPN or died prior to discharge. There was an increase in patients referred for remote discharge from 13 in 2012 to 43 in 2017. The mean number of days between receipt of referral by the IFU to discharge on HPN from the oncology centre reduced from 29.4 days to 10.1 days. Following remote discharge, the mean number of days on HPN was 215.9 days. Catheter-related blood stream infection rates in this cohort were very low at 0.169 per 1000 catheter days. CONCLUSIONS This is the first study to demonstrate the remote safe, effective and rapid discharge of patients requiring palliative HPN between two hospital sites. This allows patients with a short prognosis more time in their desired location.
