Abstract
A widely hypothesized but complex transition from widespread fluvial activity to predominantly aeolian processes is inferred on Mars based on remote sensing data observations of ancient landforms. However, the lack of analysis of in situ martian fluvial deposits hinders our understanding of the flow regime nature and sustainability of the martian fluvial activity and the hunt for ancient life. Studying analogs from arid zones on Earth is fundamental to quantitatively understanding geomorphic processes and climate drivers that might have dominated during early Mars. Here we investigate the formation and preservation of fluvial depositional systems in the eastern Sahara, where the largest arid region on Earth hosts important repositories of past climatic changes. The fluvial systems are composed of well-preserved single-thread sinuous to branching ridges and fan-shaped deposits interpreted as deltas. The systems' configuration and sedimentary content suggest that ephemeral rivers carved these landforms by sequential intermittent episodes of erosion and deposition active for 10-100s years over ∼10,000 years during the late Quaternary. Subsequently, these landforms were sculpted by a marginal role of rainfall and aeolian processes with minimum erosion rates of 1.1 ± 0.2 mm/yr, supplying ∼96 ± 24 × 1010 m3 of disaggregated sediment to adjacent aeolian dunes. Our results imply that similar martian fluvial systems preserving single-thread, short distance source-to-sink courses may have formed due to transient drainage networks active over short durations. Altogether, this study adds to the growing recognition of the complexity of interpreting climate history from orbital images of landforms.

Abstract
A wound is a temporary break in the continuity of the protective skin barrier. Wound healing is central in maintaining the body's normal homeostatic mechanism, and open wounds raise the risk of microbial infection and amputation. A successful wound healing event is achieved through a series of evolutionarily conserved biochemical pathways orchestrated by various cytokines, growth factors, and immune cells. Chronic wounds are generally oxygen-deficient, and wound hypoxia impairs the wound healing process. Therefore, the use of external oxygen may improve wound health by reducing wound hypoxia, promoting tissue regeneration and granulation tissue formation, reducing anaerobic bacteria colonization, and promoting the growth of beneficial aerobic bacteria. Relevant data were searched and gathered from scientific databases, including PubMed, ScienceDirect, and Google Scholar using relevant keywords, such as "Chronic Wounds", "Topical Oxygen Therapy", "Inflammatory Markers/ Lactate/ Matrix Metalloproteinase", "Collagen", and "Wound Healing". Relevant articles were shortlisted and used in the present study. Chronic wounds show higher expression of pro-inflammatory mediators, such as C-reactive protein, and higher levels of tissue-degrading matrix metalloproteinases. In addition, chronic wounds are generally oxygen-deficient, and wound hypoxia is directly associated with wound deterioration. Several microbial, immunological, and biochemical markers show a direct association with the oxygen availability in the wound. Therefore, a detailed understanding of these microbial, immunological, and biochemical markers will certainly help clinicians understand the interplay between various factors and topical oxygen therapy and may improve patient outcomes.

Abstract
BACKGROUND With the progression of Coronavirus infectious disease-19 (COVID-19), various neurological manifestations have been noticed in these patients and Bell's palsy is one of the peripheral neuropathies among those. Bell's palsy has been associated with various other viral agents. Its evidence in patients with COVID-19 signifies the possibility of association between Bell's Palsy and Severe acute respiratory syndrome coronavirus-2 (SARS-CoV2). OBJECTIVE To evaluate the number of published cases of Bell's palsy as the only major neurological manifestation in patients with COVID-19 from March 2020 to December 2021 and to investigate the association of SARS-CoV2 and Bell's palsy. MATERIALS AND METHODS A systematic review of the published English literature was performed using an electronic search in PubMed / Medline, Scopus, Research gate, Research square and Google Scholar databases, using keywords like 'COVID-19' OR/AND 'SARS-CoV-2', OR/AND 'Bell's palsy', OR/AND 'Facial nerve palsy', OR/AND 'Neurological', OR/AND 'Manifestation'. RESULTS Search strategy revealed 32 relevant publications with a total of 46 patients. Bell's palsy was the initial manifestation in 37% cases and in 63% cases it developed after COVID-19 symptoms. 71.7% cases showed complete recovery and 21.7% showed only partial relief from BP. CONCLUSIONS Although the number of documented cases in this research are not much, but evidence of Bell's palsy as the only major neurological manifestation in patients with COVID-19 signifies an important clinical finding and the possibility of another viral aetiology of BP. More evidence is needed to establish the exact co-relation between these two entities.

Abstract
BACKGROUND Herpes simplex virus encephalitis (HSVE) is one of the most common infectious causes of sporadic encephalitis. Coronavirus disease (COVID-19) has been associated with immune dysregulation of the host that might increase the risk of infections like HSVE following SARS-CoV-2 infection. There is paucity of literature on post COVID-19 HSVE. This study was conducted with the aim of analyzing the clinical presentation, brain imaging, and outcome of patients presenting with HSVE within 6 weeks of COVID-19 and providing a comprehensive review on the possible mechanisms of post-COVID-19 HSVE. METHODS This observational study included patients who had laboratory-confirmed HSVE (type 1 or type 2) and a history of COVID-19 within the previous 6 weeks. Patients were followed up for 3 months. RESULTS Eight patients were included and all of them had type 1 HSVE. The mean latency of onset of neurological symptoms from being diagnosed with COVID-19 is 23.87 days and a majority of the patients have received injectable steroids with a mean duration of 6.5 days. Behavioral abnormality was the commonest neurological presentation and typical brain imaging involved T2 FLAIR hyperintensities of the medial temporal lobes. All patients received intravenous acyclovir 10 mg/kg every eight hourly for atleast 14 days. One patient with concomitant rhinocerebral mucormycosis succumbed while the majority had a complete recovery. CONCLUSION Possible immune dysregulation in COVID-19 may increase the susceptibility of HSVE in patients with a history of recent SARS-CoV-2 infection. The clinical manifestations and laboratory findings of HSVE in such patients are similar to typical HSVE.

Abstract
OBJECTIVE The aim of this study is to compare the risk of venous thromboembolic events (VTE) between patients suspending and continuing estrogen therapy perioperatively, in male to female gender-affirming surgery (vaginoplasty). MATERIALS AND METHODS The authors conducted a systematic review and meta-analysis of existing research on male to female gender-affirming study, which compared the risk of VTE among the usage of estrogen perioperatively. RESULTS A total of 209 studies were identified as potentially eligible among PubMed, Embase, and Cochrane library databases. Among the studies, 191 studies were excluded due to their abstract inappropriateness. Out of the remaining 18 studies, only 3 articles were eligible and were finally included. Meta-analysis was performed and showed odds ratio of 0.77 (95% CI: 0.04, 14.01). CONCLUSIONS Perioperative estrogen therapy does not increase VTE risk on male to female gender-affirming surgery. Therefore, estrogen therapy may be continued perioperatively in vaginoplasty. More prospective studies are needed.

Background: Studies showed olfactory disturbances in COVID patients. This has attracted focus of clinicians as an easy clinical screening tool in suspected population. Material and methods: 70 mild and moderate category COVID-19 RT-PCR positive patients, more than 10 years of age were tested on day of admission for olfaction with serial dilution of n-butanol and asked to grade severity of their olfactory dysfunction according to visual analogue score from 1-10. Results: Fatigue 42 (93.33%), sore throat 37 (82.22%), fever 36 (80%) and dyspnea 23 (51.11%) were the most common symptoms in moderate patients. Diabetes, hypertension and allergy were the three prominent risk factors. At time of admission, n-butanol diagnosed 20 patients having olfactory dysfunction compared to 11 by VAS. Patients tend to grade their dysfunction higher on VAS whereas the n-butanol test classified their olfactory dysfunction lower. Viral load and high CRP were not found to be significantly related with olfactory dysfunction. d-Dimer and LDH levels were found statistically associated with higher grading of olfactory dysfunction detected by n-butanol. Conclusion: The majority of cases developed hyposmia before they were admitted to hospital even before they realized that they were having hyposmia as revealed by n-butanol testing. We should go for objective tests of olfaction.

Abstract
Background Long-term storage of tissue slides has been reported to induce reduced biomarker (e.g. proteins and messenger RNA) detection. This study aimed to evaluate the impact of long-term storage time (0, 16, 24 and 36 weeks) and treatment conditions (non-paraffin and paraffin dipping) at 4°C on RNA quality in formalin-fixed and paraffin-embedded (FFPE) tissue sections. Materials and methods NanoString GeoMx Digital Spatial Profiling (DSP), a novel platform that allows spatial profiling, was used to profile RNA in human bladder cancer FFPE tissue sections. Results We observed excellent consistency of quantitative DSP RNA counts of all targets between two different treatment conditions (R > 0.97, Pearson correlation) at each time point and among all four different storage time points (R > 0.96, Pearson correlation) within each treatment condition. No significant difference was observed in the percentage of target genes with sufficient signal across two different treatment conditions at any time point (0 week, P = 0.96; 16 weeks, P = 0.76; 24 weeks, P = 0.96; 36 weeks, P = 0.76, Kolmogorov–Smirnov test) and across all four different storage time points (P > 0.05, Kolmogorov–Smirnov test) in either treatment condition. Conclusion Although both treatment conditions provided similar results in terms of count reproducibility and signal preservation, we recommend paraffin dipping to generate reproducible RNA results and optimize sample storage. Technology behind the NanoString GeoMx DSP platform shows a robust and reproducible RNA signal from multiple targets in the FFPE tissue sections stored at 4°C for at least up to 36 weeks. Long-term storage of FFPE sections has been reported to induce reduced antigen detection especially for RNA. This study evaluated the impact of storage times and treatment conditions on FFPE sections. The GeoMx DSP system, a novel platform that allows spatial RNA profiling, has been utilized. Long-term antigenicity preservation of quantitative DSP RNA counts was reported among storage times and treatment conditions. This finding is valuable in low resourced settings where routine access to FFPE blocks is challenging.

Abstract
Abstract
Aim
To assess operative decision-making for patients with neck of femur fractures.
Method
2-year retrospective analysis of 150 patients in a single centre looking at outcomes focusing on complication rates and mortality.
Results
Mortality stood at 6% at 1 month and 25% at 1 year compared to quoted literature (10% at 1 month and 30% at 1 year). Surgical complication rates varied between fracture pattern and operative choice. Notably, the use of cannulated screws in displaced intracapsular fractures had a very high rate of failure at 80% (4 out of 5) compared to 0% for dynamic hip screws (0 out of 5). In undisplaced intracapsular fractures, the failure rate of cannulated screws remains high at 15% (2 out of 13) which is in-keeping with current literature. Surgical complications of hemi-arthroplasty remain low with only 3 out of 73 patients having significant complications (intra-operative fracture, dislocation, and acetabular erosion).
Conclusions
Cannulated screw fixation should be carefully considered, especially in the setting of displaced intracapsular fractures. Hemi-arthroplasty or two-hole DHS may have superior results in the fracture pattern and indeed, in undisplaced fractures.

Abstract
Background Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are complementary techniques for large (≥ 20mm) non-pedunculated rectal polyps (LNPRPs). A mechanism for appropriate technique selection has not been described. Aims To evaluate whether a selective resection algorithm using EMR and ESD, based on real-time optical evaluation, optimizes oncologic outcomes for LNPRPs Methods We evaluated the performance of a selective resection algorithm (SRA; 08/2017-04/2021) compared to a universal EMR algorithm (UEA; 07/2008-07/2017) for LNPRPs within a prospective observational study. In the SRA, LNPRPs with features of superficial submucosal invasive cancer (SMIC < 1000μm; S-SMIC; Kudo pit pattern Vi), or with an increased risk of SMIC (Paris 0-Is or 0-IIa+Is non-granular, 0-IIa+Is granular with a dominant nodule ≥ 10mm) underwent ESD. The remaining LNPRPs underwent EMR. Algorithm performance was evaluated by SMIC identified after EMR, curative oncologic resection (R0 resection, S-SMIC, absence of negative histologic features), technical success, adverse events, and recurrence at first surveillance colonoscopy. Results 480 LNPRPs were evaluated (290 UEA, 190 SRA). Median lesion size was 40mm (IQR 30-60mm). In the SRA, 103 (54.2%) and 87 (45.8%) LNPRPs underwent EMR and ESD, respectively. SMIC was identified in 56 (11.7%) LNPRPs. Significant differences in SMIC after EMR (SRA 1 (1.0%) vs. UEA 35 (12.1%); p = 0.001), curative oncologic resection (SRA 7 (33.3%) vs. UEA 2 (5.7%); p = 0.010), and recurrence (SRA 2 (1.6%) vs. UEA 40 (17.2%); p < 0.001) were identified. No significant differences in technical success or adverse events were identified (all p > 0.137). Among potentially curable malignant LNPRPs which underwent ESD, 100% (7/7) were cured. Conclusions A SRA optimizes oncologic outcomes for LNPRPs and mitigates the risk of piecemeal resection of cancers. Funding Agencies The Cancer Institute of New South Wales provided funding for a research nurse and data manager to assist with the administration of the study. Neal Shahidi was supported by the University of British Columbia Clinician Investigator Program.

Abstract
Abstract
Background
The Paris classification is an international classification system that characterizes the morphology of superficial gastrointestinal tract neoplasms. Given its ability to predict the risk of submucosal invasion, this tool plays an important role in the preliminary endoscopic assessment of early gastrointestinal neoplastic lesions. Despite its international prevalence, there are no pooled reliability analyses to assess agreement amongst endoscopists using this classification system.
Aims
To systematically review and meta-analyze the interobserver reliability (IOR) of the Paris classification system.
Methods
We conducted a systematic review and meta-analysis according to the PRISMA recommendations. A comprehensive literature query was conducted on biomedical databases through December 2020. Studies were included if they quantitively evaluated the IOR of the Paris classification with at least 5 endoscopists participating in the study cohort. Two authors independently screened studies and abstracted data using an a priori designed data collection form. We pooled the results of studies which provided IOR with kappa statistics and confidence intervals using DerSimonian and Laird random effects models. Risk of bias was independently assessed by two study authors using the Guidelines for Reporting Reliability and Agreement Studies (GRRAS) tool.
Results
From an initial 1541 studies, 5 were included in the qualitative review and 3 reported data that allowed for a quantitative analysis of the primary outcome, representing a total of 28 endoscopists. All three of these studies were high quality. The IOR for the Paris classification amongst all endoscopists was 0.541 (95% CI, 0.466–0.617). There was no significant improvement (p=0.551) in the IOR of the Paris classification system following an educational training intervention (pre-education pooled kappa, 0.498; 95% CI, 0.429–0.567 compared to post-education pooled kappa, 0.530; 95% CI, 0.451–0.608).
Conclusions
Interobserver reliability of the Paris classification is moderate with no significant improvement following educational intervention.

Abstract
Abstract
Background
Optical diagnosis relies on the ability of the endoscopist to visualize normal and abnormal patterns on the epithelial surface of the gastrointestinal tract. With ongoing technologic advances in image-enhanced and magnifying endoscopy, there has been more attention given to improving our ability to visually evaluate and classify lesions as this can help guide decisions around resection techniques. However, the accuracy of optical diagnosis of epithelial lesions remains under investigated.
Aims
To analyse (1) the presence or absence of descriptive details (size, gross morphology, and classification systems used) of lesions of interest within the endoscopy report and (2) the accuracy of the optical diagnosis, when stated, as compared to the final pathology report.
Methods
This is a single-centre retrospective chart review and quality improvement initiative conducted at St. Michael’s Hospital, Toronto, Ontario. All patients who had polypectomy performed between January 1st, 2019 and December 31st, 2020 for polyp(s) > 10mm in size, were eligible for study inclusion. Patients were excluded if polyps did not meet the size criteria, the polyp was not resected, or absent documentation. Descriptive statistics were conducted.
Results
2100 patients had polypectomies during the study period. 714 patients with 833 polyps >10mm in size were included in the data analysis. Estimated size was reported for 93% of polyps, gross morphology for 68%, and a classification system for 72%. All three description parameters were reported for 52% of polyps. Predicted pathology was recorded in 41% of polyps. When documented, the accuracy of optical diagnosis was 71%.
Conclusions
In our study, the presence of key descriptive details attributed to polyps at the time of polypectomy was lower than expected. In addition, an optical diagnosis was documented in less than half of the time. Finally, the overall accuracy of optical diagnosis was lower than predicted potentially related to the underreporting and underutilization the important predictors of submucosal invasion. Considering that making real-time endoscopic diagnoses has major implications on treatment decisions, it is imperative that we work on these skills to improve patient outcomes (increasing R0 resection rates, decreasing recurrence and avoiding unnecessary surgeries). Through this project, recommendations will be made regarding the implementation of synoptic reporting in addition to guiding future quality improvement initiatives.

Abstract
Abstract
Background
Patients with inflammatory bowel disease (IBD) involving the colorectum are at higher risk for the development of flat and poorly delineated dysplastic lesions. Pancolonic dye spray chromoendoscopy (DCE) can represent an adjunct to white light endoscopy (WLE) that enhances detection and delineation of such lesions.
Aims
We evaluated the utility of follow-up DCE for lesion detection and treatment in patients with IBD who had visible (polypoid or flat lesions) or invisible (identified in non-targeted biopsies) dysplasia detected during high-definition (HD)-WLE.
Methods
We retrospectively studied patients with colonic IBD from The Ottawa Hospital who underwent DCE by a trained endoscopist, as follow-up for dysplasia detected during HD-WLE, over a 7-year time period (2013–2020). We collected demographic and disease-specific variables.
Results
Twenty-four patients were included (mean age 56.7±13.8 years, 50.0% male, 70.8% ulcerative colitis, mean disease duration 18.0±11.0 years, 70.8% moderate or severe disease activity historically, and 41.7% remote history of dysplasia). Seventeen (70.8%) patients were referred following detection of invisible dysplasia; the remainder (29.2%) were referred for surveillance of poorly defined visible dysplastic lesions. For those referred following detection of invisible dysplasia, DCE identified visible dysplasia at the same site in 8/17 (47.1%) patients, at a different site in 6/17 (35.3%) patients, and no dysplasia in 3/17 (17.6%) patients. DCE identified 1.39±1.50 new visible dysplastic lesions per patient that were not identified on index HD-WLE. DCE upgraded the highest grade of dysplasia and diagnosed colorectal cancer in 2/24 (8.3%) patients, which was missed on index HD-WLE. Endoscopic resection was successful in 23/34 (76.7%) dysplastic lesions identified on DCE. However, DCE was unable to facilitate lesion resection in three patients due to advanced lesion characteristics. Follow-up data was available for 17/24 (70.8%) patients (mean 0.88±0.58 years). Of these patients, 7/17 (41.2%) developed subsequent dysplasia, including 4/17 (23.5%) at a site of prior invisible dysplasia, 2/17 (11.8%) at sites of prior visible dysplasia, and 1/17 (5.88%) at a different site. One of these patients developed high-grade dysplasia requiring resection.
Conclusions
In this study, DCE is a valuable tool for dysplasia detection and treatment in persons with colonic IBD who have ill-defined dysplasia identified during HD-WLE. Given some patients developed dysplasia following DCE in our cohort, it is important to maintain close follow-up and obtain biopsies around sites of prior invisible and visible dysplasia. Further studies are required to validate our findings.

Abstract
BACKGROUND Pulmonary fibrosis is a debilitating condition with limited therapeutic avenues. The pathogenicity of pulmonary fibrosis constitutes involvement of cellular proliferation, activation, and transformational changes of fibroblast to myofibroblasts. It is a progressive lung disease and is primarily characterized by aberrant accumulation of extracellular matrix proteins in the lungs with poor prognosis. The inflammatory response in the pathogenesis of lung fibrosis is suggested because of release of several cytokines; however, the underlying mechanism remains undefined. A genetic model is the appropriate way to delineate the underlying mechanism of pulmonary fibrosis. METHODS AND RESULTS In this report, we have used cc-10 promoter based IκBα mutant mice (IKBM, an inhibitor of NF-κB) which were challenged with bleomycin (BLM). Compared to wild-type (WT) mice, the IKBM mice showed significant reduction in several fibrotic, vascular, and inflammatory genes. Moreover, we have identified a new set of dysregulated microRNAs (miRNAs) by miRNA array analysis in BLM-induced WT mice. Among these miRNAs, let-7a-5p and miR-503-5p were further analyzed. Our data showed that these two miRNAs were upregulated in WT-BLM and were reduced in IKBM-BLM mice. Bioinformatic analyses showed that let-7a-5p and miR-503-5p target for endothelin1 and bone morphogenic receptor 1A (BMPR1A), respectively, and were downregulated in WT-BLM mice indicating a link in pulmonary fibrosis. CONCLUSION We concluded that inhibition of NF-κB and modulation of let-7a-5p and miR-503-5p contribute a pivotal role in pulmonary fibrosis and may be considered as possible therapeutic target for the clinical management of lung fibrosis.

Abstract
Biliary obstruction from metastatic deposits in the pancreas is rare. We present a case of primary testicular lymphoma (PTL) with pancreatic metastasis. A 56-year-old man presented to the general surgical department with signs and symptoms of obstructive jaundice. A computed tomography scan revealed multiple pancreatic metastases and a right primary testicular malignancy. Histology and positron emission tomography scanning subsequently confirmed PTL with pancreatic metastases. Metastasis to the pancreas from primary testicular malignancy is extremely rare. There is variation in prognosis between primary and secondary pancreatic malignancies and therefore in atypical cases of malignant biliary obstruction consideration must be given to the rarer secondary malignancies.

Abstract
Sialadenoma papilliferum (SP) is a rare benign tumor usually occurring in the minor salivary glands. Only two cases of malignant transformation of SP and an occasional case of dysplasia in SP have been reported in the literature till now. We report a case of SP of a minor salivary gland in a middle-aged male where the exophytic component retained the histomorphological features of SP while the endophytic component displayed characteristics of a mucoepidermoid carcinoma. Malignant change in sialadenoma papilliferum is an extremely rare phenomenon that requires further research and documentation. Careful evaluation of morphologic features and reporting of more such cases is required to delineate the clinical behavior of this unusual tumor.

Abstract
Metastasis is one of the most common consequences of malignant tumors, and it is one of the leading causes of morbidity and mortality. Metastatic cancers to oral cavity are extremely rare. Moreover, the true incidence has yet to be determined. Despite their rarity, they are important clinically, since they can be the first and the only evidence of spread in many situations. Breast, kidney, lung, prostate and gastrointestinal tract are the most common sources of metastases in the oral cavity. Thyroid carcinoma is the most prevalent type of endocrine cancer, yet it rarely spreads to the oral cavity. After papillary thyroid carcinoma, follicular thyroid carcinoma is the second-most frequent kind of thyroid cancer. Jawbones are more commonly affected than soft tissues. Literature research revealed that till date, 44 cases of metastatic follicular thyroid cancer to the jawbones have been documented with mandibular preponderance (40 cases). With the rising occurrence of oral metastatic tumors in recent years, it has become increasingly important to diagnose them early to avoid future consequences. We present here an unusual case of metastatic follicular thyroid cancer in the mandible of an elderly adult along with a comprehensive review of the literature.

Abstract
Background Hairdressers undergo extensive and prolonged exposure to a variety of chemical substances present in the air in their salons. Although in low concentrations, the various products used for hair care are harmful as most of these products generate chemical aerosols during different procedures. These aerosols which have irritant or sensitizing effects on respiratory mucosa have been found to enter into the airways. Aim The aim of this study is to assess the impairment of lung function in hairdressers in Gangtok. Method This is a cross-sectional, comparative study conducted on 50 hairdressers and 50 age- and sex-matched non-hairdresser comparison group. The sampling technique used was simple random sampling. Permission from Institutional Ethical Committee was obtained before beginning the study. A standard questionnaire was used to record the respiratory symptoms. The pulmonary function parameters of the subjects were measured using portable spirometer HELIOS 720. Results All the parameters were decreased in hairdressers and almost all the differences were statistically significant. FEV1 (P = 0.023) and FEV1/FVC ratio (P < 0.05) were reduced significantly. FEF25-75% and PEFR were also significantly reduced (P < 0.05 in both parameters). FVC was also reduced in hairdressers, but it was not statistically significant (P = 0.342). Conclusion Hairdressers undergo exposure to different chemicals in their workplace and carry the risk of decreased pulmonary function.

Abstract
BACKGROUND/OBJECTIVES Diagnosis of pancreatic cancer is often delayed, contributing to patient and family distress and leading to worse survival. We aimed to develop a decision support tool to support primary care providers to identify patients that should undergo investigations for pancreatic cancer, and to recommend initial diagnostic pathways. METHODS A modified Delphi process, including a series of three surveys, was undertaken to ascertain clinical expert opinion on which combinations of signs, symptoms and risk factors should be included in a tool for the early identification of pancreatic cancer. A group of clinical specialists finalised the development of the tool during a focus group meeting. RESULTS The tool presents individual or combinations of signs, symptoms, and risk factors in three tiers which direct the urgency of investigation. Tier 1 includes 5 clinical presentation and risk factors clusters that indicate the need for urgent investigation of the pancreas. A further five clusters are included as Tier 2 aiming to elimate other causes and reduce the time to investigating the pancreas. Tier 3 includes a list of non-specific signs, symptoms and risk factors that indicate the need to consider pancreatic cancer as a potential diagnosis, but without specific recommendations for investigation. CONCLUSIONS Prospective validation studies are now required prior to implementation in the primary care setting. Implementation into primary care practice and as an educational resource may facilitate rapid diagnosis and improve outcomes such as distress and survival.

Abstract
BACKGROUND Young (≤40 years) breast cancers (YBC) are uncommon, inadequately represented in trials and have unique concerns and merit studying. METHODS The YBC treated with a curative intent between 2015 and 2016 at our institute were analysed. RESULTS There were 1228 patients with a median age of 36 (12-40) years; 38 (3.1%) had Stage I, 455 (37.1%) - II, 692 (56.3%) -III, and remaining 43 (3.5%) Stage IV (oligo-metastatic) disease; 927 (75.5%) were node positive; 422 (34.4%) were Triple negatives (TNBC), 331 (27%) were HER-2 positive. There were 549 (48.2%) breast conservations and 591 (51.8%) mastectomies of which 62 (10.4%) underwent breast reconstruction. 1143 women received chemotherapy, 617 (53.9%) received as neoadjuvant and 142 (23.1%) had pathological complete response; 934 (81.9%) received adjuvant radiotherapy. At the median follow-up of 48 (0-131) months, 5-year overall and disease-free survival was 79.6% (76.8-82.5) and 59.1% (55.8-62.6). For stage I, II, III and IV, the 5-year overall-survival was 100%, 86.7% (82.8-90.6), 77.3% (73.4-81.2), 69.7% (52.5-86.9) and disease-free survival was 94% (85.9-100), 65.9% (60.3-71.5), 55% (50.5-59.5), and 29.6% (14-45.2) respectively. On multivariate analysis, TNBC and HER-2+ subgroups had poorer survival (p = 0.0035). 25 patients had BRCA mutations with a 5-year DFS of 65.1% (95% CI:43.6-86.6). Fertility preservation was administered in 104 (8.5%) patients; seven women conceived and 5 had live births. Significant postmenopausal symptoms were present in 153 (13%) patients. CONCLUSION More than half of the YBC in India were diagnosed at an advanced stage with aggressive features leading to suboptimal outcomes. Awareness via national registry and early diagnosis is highly warranted. Menopausal symptoms and fertility issues are prevalent and demand special focus.

Abstract
Aim: To determine the risk factors affecting outcome at the end of 90 days of post-angiogram-negative subarachnoid hemorrhage (SAH). Methods: Non-traumatic SAH cases were reviewed from the case records of patients who had reported to the Department of Neurology of a tertiary care hospital and 50 angio-negative SAH cases were included after excluding all the cases with known cause of hemorrhage after doing computed tomography angiography (CTA)/digital subtraction angiography (DSA). The presence of hypertension, diabetes mellitus, coronary artery disease (CAD), history of alcohol and smoking, and various scales like Hunt and Hess Scale (HHS), World Federation of Neurological Surgeons (WFNS), and Fisher scale had been recorded at admission. The outcome was assessed at 90 days post-SAH using the Modified Rankin Scale (mRS). Statistical analyses: The association between the outcome and the factors was assessed using the Pearson Chi-Square test and the risk factors/predictors of outcome were assessed using logistic regression. Results: The following variables were important risk factors for predicting poor outcome of angio-negative SAH (mRS 3 to 6): hypertension (P = 0.011), diabetes mellitus (P = 0.032), being an alcoholic (P = 0.019), HHS grade 4 to 5 (P < 0.01), and WFNS grade 4 to 5 (P < 0.01). On multivariate regression analysis, hypertension (P = 0.032) was an independent predictor of unfavorable outcome. Conclusions: At time of admission, presence of hypertension, diabetes mellitus, history of alcohol consumption, and poor grades of HHS and WFNS scale are predictors of poor outcome of angio-negative SAH.

Abstract
Biliary obstruction from metastatic deposits in the pancreas is rare. We present a case of primary testicular lymphoma (PTL) with pancreatic metastasis. A 56-year-old man presented to the general surgical department with signs and symptoms of obstructive jaundice. A computed tomography scan revealed multiple pancreatic metastases and a right primary testicular malignancy. Histology and positron emission tomography scanning subsequently confirmed PTL with pancreatic metastases. Metastasis to the pancreas from primary testicular malignancy is extremely rare. There is variation in prognosis between primary and secondary pancreatic malignancies and therefore in atypical cases of malignant biliary obstruction consideration must be given to the rarer secondary malignancies.

Abstract
BACKGROUND Solitary fibrous tumours (SFT) are a type of mesenchymal tumour. Whilst the majority of cases follow an indolent course a significant proportion of patients suffer metastases or disease recurrence post-surgical excision. Due to the unpredictable clinical course follow up duration and intensity remains contentious. AIMS We aimed to determine current outcomes of management of this tumour, apply and assess current risk recurrence models to determine if our standard of care could be improved upon. METHODS AND PATIENTS A prospective database of patients treated at a regional musculoskeletal oncology service was assessed. Only extra-pleural, extra-meningeal SFTs were included in the study. Surgical outcome and post-operative investigations were scrutinised and the Pasquali and Demicco recurrence risk models were applied and assessed. RESULTS From 2009 to 2019 12 patients were identified, 8 female and 4 males. Their age at diagnosis ranged from 21 to 76 years. 11 patients underwent surgery with curative intent and no patient suffered disease progression or recurrence, with a mean follow up time of 41 months. One patient presented with metastatic disease and was managed palliatively. CONCLUSIONS Following this review of our case series and utilising risk recurrence models published in the literature we have changed our follow up protocol. In new cases of SFT the Pasquali prognostic model, with the addition of the presence or absence of necrosis, will be utilised. If a patient has benign features on initial biopsy we propose to not perform staging. Furthermore, if biopsy and final pathology results remain concordant, with no concerning features, and the patient has undergone complete excision reduced intensity follow up could be considered.Level of evidence Level IV, retrospective case series.

Abstract
Posttraumatic stress disorder (PTSD) is a common psychiatric disorder for military Veterans, characterized by hyperarousal, intrusive thoughts, flashbacks, hypervigilance, and distress after experiencing traumatic events. Some of the known physiological effects of PTSD include hypothalamic-pituitary-adrenal (HPA)-axis imbalance, a cortical function resulting in neuronal deficit and changes in behavior. Moreover, excessive discharge of inflammatory molecules and a dysregulated immune system are implicated in the pathophysiology of PTSD. Due to complex nature of this disorder, the biological underpinnings of PTSD remain inexplicable. Investigating novel biomarkers to understanding the pathogenesis of PTSD may reflect the underlying molecular network for therapeutic use and treatment. Circulatory microRNAs (miRNAs) and exosomes are evolving biomarkers that have shown a key role in psychiatric and neurological disorders including PTSD. Given the unique nature of combat trauma, as well as evidence that a large portion of Veterans do not benefit from frontline treatments, focus on veterans specifically is warranted. In the present review, we delineate the identification and role of several miRNAs in PTSD among veterans. An association of miRNA with HPA-axis regulation through FKBP5, a key modulator in PTSD is discussed as an emerging molecule in psychiatric diseases. We conclude that miRNAs may be used as circulatory biomarker detection in Veterans with PTSD.

Abstract
AIMS To determine the factors influencing the outcomes of patients with recurrences post-hysterectomy for cervical cancers treated with external beam radiotherapy (EBRT) and interstitial brachytherapy. MATERIALS AND METHODS This prospective study accrued 90 patients between October 2008 and May 2014. All patients had had a prior hysterectomy and were diagnosed with recurrent vaginal apex cancers with squamous cell carcinomas. All underwent EBRT of 50 Gy (2 Gy/fraction) using tomotherapy-based image-guided intensity-modulated radiotherapy with concurrent chemotherapy of weekly cisplatin (40 mg/m2) followed by high dose rate interstitial brachytherapy boost of 20 Gy (4 Gy/fraction twice a day). Local relapse, disease-free and overall survival were determined. RESULTS At a median follow-up of 74 months (4-123 months), 10/90 (11%) patients had local failure as the first site of relapse and 12/90 (13.3%) had first distant relapse. Only one patient had synchronous local and distant relapse. The 7-year local relapse-free, disease-free and overall survival were 87.6, 68.3 and 68.3%, respectively. Grade 2 and 3 rectal toxicity were seen in 5.6 and 3.1% of patients, respectively. Among these, two (2.2%) patients underwent temporary diversion colostomy due to vaginal sigmoid and rectovaginal fistula. Grade 2 and 3 bladder toxicity were seen in 5.6 and 1.1% of patients, respectively. In summary, the lateral disease extent (P = 0.048) and the presence of nodal disease at diagnosis (P = 0.08) had a statistically significant or borderline impact on local relapse without any impact on disease-free survival. Tumour size in itself did not affect overall survival. CONCLUSION With the integration of EBRT and interstitial brachytherapy, most vaginal apex recurrences can be salvaged. An excellent local control and survival is achievable using intensity-modulated radiotherapy with image guidance and concurrent chemotherapy followed by high dose rate interstitial brachytherapy.

Abstract
Abstract
Objectives
This systematic review examined the correlation between the different types of migrant acculturation strategies according to Berry's model of acculturation (integration, assimilation, separation, marginalisation) and their effects on mental health.
Methods
Three databases (PubMed, Ovid and Ebsco) were searched using different combinations of terms to identify relevant articles. Search terms included relevant synonyms for “migrants”, “mental health” and “integration”. The list of article titles from these searches were filtered using inclusion and exclusion criteria. Common mental health conditions including suicide/self-harm, depressive disorders, psychosis, as well as substance misuse were analysed.
Results
21 primary studies were examined, which assessed 61,885 migrants in total. Of these, 7 were cohort studies and 14 were cross-sectional studies. Most studies showed that marginalisation was associated with worse depression symptoms, compared to integration, assimilation and separation, while integration was associated with the least depressive symptoms. Marginalisation triples the likelihood of anxiety-related symptoms compared to integration. Similarly, separation increased the likelihood of anxiety-related symptoms nearly six-fold. Our study has also identified 16 factors that negatively impact level of migrant acculturation, 19 factors that adversely impact general mental health of migrants, and 22 factors that increases risks of depressive symptoms in migrants.
Conclusions
Our review found out that marginalisation had the worst effects on migrant mental health while integration had the most positive effects. The study also established multiple factors associated with low levels of acculturation and poor mental health in migrants. Given the problem of limited public resources, governments can identify at-risk individuals using factors highlighted and channel these scarce resources to develop targeted mental health interventions for them.
Key messages
Our review found out that marginalisation had the worst effects on migrant mental health while integration had the most positive effects. The study identified factors associated with low levels of acculturation and poor mental health in migrants. Governments can develop targeted mental health interventions for these at-risk individuals.
