Abstract
AIMS Differential attainment (DA) in post graduate medical training is a recognised challenge and refers to unexplained variation across groups when split by several protected characteristics. The Royal College of Radiology is committed to fostering diversity, inclusivity, and equality with the goal of narrowing existing gaps and improving training outcomes. MATERIALS AND METHODS This was a mixed methods study aiming to understand the causes of DA with view to helping the RCR develop strategies to address this. A cross-sectional survey was completed by 140 clinical oncology trainees in September 2022. Trainees and trainers (17 and 6 respectively) from across England, Scotland, Wales and Northern Ireland, took part in focus group and interviews from August to December 2022. Quantitative and qualitative data merged and interpreted. RESULT Results showed international medical graduates and trainees from ethnic minority backgrounds were more likely to encounter challenges. The qualitative findings were used to identify three themes through which these problems could be framed. The trainee as a "space invader," the hidden curriculum of clinical oncology training and the process of navigating and tacking the training journey. CONCLUSION Differential attainment is the product of a complex interplay between the trainee, trainer, and the training environment. Therefore, interventions must be tailored to different people and contexts. At a national level, the RCR can adopt general policies to promote this such as mentorship programmes, protected time for supervision and cultural competency training. Efficacy of proposed interventions for trial and their impact on DA should be evaluated to drive evidence-based changes.

Abstract
AIM The optimum surgical approach to splenic flexure cancers (SFCs) remains uncertain. The aim of this survey was to explore the opinions of an international surgical community on the management and outcomes of SFC. METHOD A questionnaire was constructed comprising five sections (information about respondents; definition and prognosis of SFC; operative approach; approach in specific scenarios; outcomes) and circulated through an international dissemination committee and social media. RESULTS The survey received 576 responses over 4 weeks across 50 countries. There was no consensus regarding the definition of the splenic flexure, whilst the proportion of respondents who did and did not think that patients with SFC had a worse outcome was equal. The overall preferred operative approach was left hemicolectomy [203 (35.2%)], followed by segmental resection [167 (29%)], extended right hemicolectomy [126 (21.9%)] and subtotal colectomy [7 (12%)]. The stated pedicles for ligation varied between resection types and also within the same resection. One hundred and sixty-six (28.8%) respondents thought a segmental resection was associated with the worst survival and 190 (33%) thought it was associated with the best quality of life. CONCLUSION This survey confirms a lack of consensus across all aspects SFC treatment. The differing approaches described are likely to represent different beliefs around the variable anatomy of this region and the associated lymphatic drainage. Future studies are required to address such inconsistencies and identify the optimum surgical strategy, whilst also incorporating quality-of-life metrics and patient-reported outcomes. A one-size-fits-all approach is probably not appropriate with SFC, and a more bespoke approach is required.

Abstract
Abstract Naturally occurring mutations in morphogenetic protein 15 (BMP15) are associated with decreased ovulation rate (OR), litter size (LS), and sterility. It is of a great interest to elucidate BMP15 gene in Cholistani sheep breed to uplift socio-economic status and the knowledge of Cholistani sheep breeding in Southern Punjab, Pakistan. In our study, a total of 50 infertile Cholistani sheep aged between 2-6 years and having no blood relation were screened for BMP15 mutations. For this purpose, a high-quality DNA was extracted from the blood of sheep followed by primer designing, Polymerase Chain Reaction (PCR) amplification, DNA sequencing, and in silico analyses. Out of total 50 samples, 9 samples including case 1 (T3), case 2 (T8), case 3 (T17), case 4 (T22), case 5 (T25), case 6 (T33), case 7 (T40), case 8 (T44), and case 9 (T47) were found positive for a variety of already reported and novel BMP15 mutations. Further in silico analyses of the observed mutations have shown the functional impact of these mutations on different characteristics (molecular weight, theoretical PI, estimated half-life, instability index, sub-cellular localization, and 3D confirmation) of the encoded proteins, possibly altering the normal functionality. In a nutshell, findings of this study have confirmed the possible essential role of the BMP15 mutations in the infertility of the Cholistani sheep.

Abstract
The use of dermal fillers for cosmetic procedures has increased rapidly both worldwide and in the Netherlands in recent years, which has led to an absolute increase in reported side effects and complications. Although most of these complications are mild, serious complications such as vascular occlusion can also occur. In this article, we describe a case of a 35-year-old woman who showed signs of reduced tissue perfusion and the early stage of skin necrosis following injection of hyaluronic acid fillers in the chin. This complication was successfully treated by ultrasound-guided injection of hyaluronidase, resulting in a full recovery without residual symptoms. To minimize the risk of serious complications treatment with hyaluronic acid fillers should be carried out by an experienced practitioner.

Abstract
OBJECTIVE The objective of this study was to clone and express the hepatitis B surface antigen gene (HBsAg) in Escherichia coli (E. coli), thereby aiming to develop potential local therapeutics for combating Hepatitis B virus (HBV) infection in the Pakistani community by producing HBsAg in E. coli. MATERIALS AND METHODS Blood serum samples were collected from hepatitis B-infected patients, and their genomic DNA was extracted. Real-time and nested polymerase chain reaction (PCR) was performed to amplify the HBsAg gene. The gene of interest was cloned into the pET20b expression vector and transformed into E. coli BL21 (DE3) using Isopropyl β-D-1-thiogalactopyranoside (IPTG) induction. The gene's precise size was confirmed with gene-specific external and internal primers (681 bp and 400 bp, respectively). RESULTS The HBsAg gene was successfully sequenced and submitted to GenBank, exhibiting 98% homology with targeted HBV sequences worldwide. The expression of HBsAg protein was confirmed through silver staining, Coomassie staining, western blot, and dot blot analysis. CONCLUSIONS The expressed protein clones are now available for further development as a local recombinant DNA vaccine to prevent hepatitis B viral infection in the local community.

Abstract
Bruxism is a disabling condition in which unconscious contractions of the masticulatory muscles lead to teeth grinding and jaw clenching. Symptoms include toothache, temporomandibular dysfunction, headache and attrition. Treatment options range from conservative approaches to invasive interventions. Education, stress reduction, avoidance of stimulants, and relaxation techniques can help in mild cases. Wearing an occlusal splint can reduce attrition. Botulinum neurotoxin type A (BoNT-A) injections are a treatment option temporarily causing partial paralysis of the masticulatory muscles. BoNT-A is a treatment for reducing symptoms and improving the quality of life of patients with bruxism that has been proven safe and effective. The effects usually last several months. To achieve the best results and minimize side effects, BoNT-A injections should be applied by an experienced practitioner.

Abstract
Shock Ignition is a two-step scheme to reach Inertial Confinement Fusion, where the precompressed fuel capsule is ignited by a strong shock driven by a laser pulse at an intensity in the order of [Formula: see text] W/cm[Formula: see text]. In this report we describe the results of an experiment carried out at PALS laser facility designed to investigate the origin of hot electrons in laser-plasma interaction at intensities and plasma temperatures expected for Shock Ignition. A detailed time- and spectrally-resolved characterization of Stimulated Raman Scattering and Two Plasmon Decay instabilities, as well as of the generated hot electrons, suggest that Stimulated Raman Scattering is the dominant source of hot electrons via the damping of daughter plasma waves. The temperature dependence of laser plasma instabilities was also investigated, enabled by the use of different ablator materials, suggesting that Two Plasmon Decay is damped at earlier times for higher plasma temperatures, accompanied by an earlier ignition of SRS. The identification of the predominant hot electron source and the effect of plasma temperature on laser plasma interaction, here investigated, are extremely useful for developing the mitigation strategies for reducing the impact of hot electrons on the fuel ignition.

Abstract
Importance Oral mucositis (OM) is a common and debilitating adverse effect observed in patients with head and neck cancer (HNC) receiving radiation therapy (RT). Previous studies examining associations between OM and clinical outcomes were performed in the era of 3-dimensional conformal RT planning with low rates of concurrent chemotherapy, and thus may not reflect current practice. Objective To prospectively assess patient-reported OM and identify its associations with clinical outcomes and quality of life. Design, Setting, and Participants This cohort study performed at a single institution included 702 consecutive patients who underwent definitive or adjuvant intensity-modulated RT (IMRT) for primary HNC from February 9, 2015, to May 27, 2022. Data were analyzed from November 28, 2022, to August 18, 2023. Main Outcomes and Measures Severity of OM was assessed based on highest reported mouth and throat soreness (MTS) score during radiotherapy according to the Oral Mucositis Weekly Questionnaire-Head and Neck Cancer survey, which was administered weekly during IMRT. Linear mixed models were used to compare mean MTS scores grouped by disease site and chemotherapy regimen. Fisher exact tests and 1-way analysis of variance tests were performed to identify associations between severity of OM and clinical outcomes. Results Among 576 eligible patients, the median age was 62.5 (IQR, 56.3-69.1) years, and 451 patients (78.3%) were men. In terms of race and ethnicity, 6 patients (1.0%) were American Indian or Alaska Native; 2 (0.3%), Asian; 31 (5.4%), Black; 8 (1.4%), Hispanic or Latino; 509 (88.4%), White; and 28 (4.9%), unknown. The most common treatment site was oropharynx (268 [46.5%]), and most patients received concurrent chemotherapy (464 [80.6%]). By the end of treatment, 360 patients (62.5%) developed severe OM and 568 (98.6%) developed some degree of OM. Linear mixed models found no significant differences in OM between HNC disease sites. Groups with greater highest severity of OM reported had higher rates of measured outcomes (listed respectively by MTS score 0, 1, 2, 3, and 4): feeding tube placement (0%, 3.6% [2 of 56], 6.6% [10 of 152], 14.7% [40 of 272], and 21.6% [19 of 88]; P = .001), hospitalization (12.5% [1 of 8], 10.7% [6 of 56], 15.1% [23 of 152], 23.9% [65 of 272], and 28.4% [25 of 88]; P = .02), opiate use (0%, 19.6% [11 of 56], 42.8%[65 of 152], 61.4% [167 of 272], and 64.8% [57 of 88]; P < .001) and experienced greater weight loss (median, -0.7 [IQR, -1.7 to -0.4] kg; median, 3.9 [IQR, 1.1 to 6.1] kg; median, 5.0 [IQR, 2.2 to 7.7] kg; median, 4.7 [IQR, 2.1 to 7.7] kg; and median, 7.7 [IQR, 2.8 to 10.6] kg; P < .001). Conclusions and Relevance In this cohort study of patients with HNC, 62.5% developed severe OM. Higher severity of OM was associated with feeding tube placement, hospitalization, opiate use, and weight loss. Improvements in OM prevention and management are needed.

Abstract
Our goal was to determine if "Nomenclature 2.0," the classification of lumbar disk pathology consensus, should be updated. We conducted a social media and e-mail-based survey on preferences regarding the use of classification on magnetic resonance spine reporting. Members of the European Society of Neuroradiology, European Society of Musculoskeletal Radiology, American Society of Neuroradiology, and American Society of Spine Radiology received a 15-question online survey between February and March 2022. A total of 600 responses were received from 63 countries. The largest number of responses came from Italy and the United States. We found that 71.28% of respondents used Nomenclature 2.0, Classification of Lumbar Disk Pathology. But classification on stenosis is used less often: 53.94% and 60% of respondents do not use any classification of spinal canal stenosis and foraminal stenosis, respectively. When queried about which part of Nomenclature needs improving, most respondents asked for a Structured Reporting Template (SRT), even though 58.85% of respondents do not currently use any template and 54% routinely use a clinical information questionnaire. These results highlight the importance of an updated Nomenclature 3.0 version that integrates the classifications of lumbar disk disease and spinal canal and foraminal stenosis. Further attention should also be directed toward developing a robust endorsed SRT.

Abstract
PURPOSE/OBJECTIVE(S) O6-methylguanine DNA methyltransferase (MGMT) MATERIALS/METHODS: is a well-established prognostic factor in patients with newly diagnosed glioblastoma (GBM). However, there is no consensus on a standardized method of threshold for MGMT testing. Previous studies have reported levels of as little as 1-3% to confer better prognosis. This study reports a single institutional experience of determining methylation status via methylation-sensitive high-resolution melting (MS-HRM). Previous literature suggests 10% cutoff for MGMT methylation using MS-HRM. We hereby report clinical outcomes using a lower threshold of 2%. MATERIALS/METHODS GBM patients treated at our institution retrospectively reviewed between the years 2013 and 2022 were included in the study. Patients who received hypofractionated radiation (<60 Gy) were excluded. All patients had MS-HRM test for MGMT methylation status. A real-time PCR assay was used to amplify a 62 base-pair region of MGMT for both methylated and unmethylated alleles. PCR products underwent HRM analysis and the fraction of methylated DNA was determined by comparison with a standard curve. Clinical data were collected retrospectively. Kaplan-Meier and log-rank tests were performed to compare survival. RESULTS A total of 181 patients with newly diagnosed GBM were initially included in this study. 42 patients treated with hypofractionated radiation were excluded. All patients received concurrent and maintenance temozolomide. Median age was 61.5 years. A total of 84 patients had MGMT methylation levels <2%, and 55 patients had MGMT methylation level ≥ 2% with a median methylation level of 28.5% (Range 0.8%-100%). Patients with MGMT methylation level ≥ 2% had an improved median overall survival (25.1 vs 16.0 months; p = 0.006) and improved median progression free survival (11.3 vs 7.9 months; p = 0.017). In a multivariable mode that included age, use of tumor-treating fields, KPS, sex, and BMI, only age, KPS, and MGMT remained significant. CONCLUSION Our institutional review confirmed low level of MGMT hypermethylation (≥ 2%) predicts improved outcome in patients with newly diagnosed GBM. Further investigation on optimal cut off level for MGMT methylation is still warranted.

Abstract
PURPOSE/OBJECTIVE(S) Glioblastoma (GBM) is the most common primary brain cancer in adults with very poor prognosis. Metabolic drivers of tumorigenesis are highly relevant within the central nervous system, where glucose is the sole source of energy. The impact of obesity on survival outcomes in patients with GBM has not been well reported and some initial results are inconsistent. This study investigates the factor of body mass index (BMI) in patients diagnosed with GBM. This study evaluated the prognostic association of BMI with survival outcomes in patients with newly diagnosed GBM. MATERIALS/METHODS Patientswith newly diagnosed GBM at our institution from 2015-2022 were included in this study. All patients were >18 years of age and received 60 Gy of radiation therapy with concurrent and adjuvant temozolomide following maximal safe resection. Through retrospective chart review, patient BMI at the time of diagnosis and overall survival (OS) were recorded. Analysis was done between patient groups of underweight/normal weight (BMI <25) and overweight/obese (BMI ≥ 25.00). The subgroup of overweight patients was also divided into subgroups of overweight (BMI 25.00-29.99) and obese (BMI≥30.00). A difference in clinical outcomes of overall survival was evaluated between the groups using Gehan-Breslow-Wilcoxon and log-rank tests. RESULTS Atotal of 393 patients met inclusion criteria. Median age 57.3 years, range 18.8-92.7. 185 female and 208 were male. 120 patients had a BMI <25 and 273 had a BMI ≥ 25.00. Median survival in patients with BMI <25 was 24.90 months and in patients with BMI ≥ 25.00, 18.20 months (p = 0.0001; HR 0.6552, 95% CI 0.5299-0.8101). We further divided patients with BMI ≥ 25.00 to 25-29.99 (n = 152) and BMI≥30.00 (n = 121). Both groups' OS were significantly worse than patients with BMI < 25 (p = 0.006). There was no difference in survival outcomes between patients with a BMI 25.00-29.99 and BMI≥30.00, with median OS 19.0 months and 18.1 months, respectively. CONCLUSION Patient baseline BMI <25 appears to be a prognostic indicator and correlates to improves overall survival for patients with newly diagnosed GBM. This study adds to the existing literature supporting overweight/obesity is associated with worse survival for GBM patients. Additional studies are warranted for further analysis of BMI and survival outcomes in GBM patients across patient demographics.

Abstract
The development of epithelial-to-mesenchymal transition (EMT) like features is emerging as a critical factor involved in the pathogenesis of acute myeloid leukaemia (AML). However, the extracellular signals and the signalling pathways in AML that may regulate EMT remain largely unstudied. We found that the bone marrow (BM) mesenchymal/fibroblastic cell line HS5 induces an EMT-like migratory phenotype in AML cells. AML cells underwent a strong increase of vimentin (VIM) levels that was not mirrored to the same extent by changes of expression of the other EMT core proteins SNAI1 and SNAI2. We validated these particular pattern of co-expression of core-EMT markers in AML cells by performing an in silico analysis using datasets of human tumours. Our data showed that in AML the expression levels of VIM does not completely correlate with the co-expression of core EMT markers observed in epithelial tumours. We also found that vs epithelial tumours, AML cells display a distinct patterns of co-expression of VIM and the actin binding and adhesion regulatory proteins that regulate F-actin dynamics and integrin-mediated adhesions involved in the invasive migration in cells undergoing EMT. We conclude that the BM stroma induces an EMT related pattern of migration in AML cells in a process involving a distinctive regulation of EMT markers and of regulators of cell adhesion and actin dynamics that should be further investigated. Understanding the tumour specific signalling pathways associated with the EMT process may contribute to the development of new tailored therapies for AML as well as in different types of cancers.

Abstract
We describe the direct measurement of the expulsion of a magnetic field from a plasma driven by heat flow. Using a laser to heat a column of gas within an applied magnetic field, we isolate Nernst advection and show how it changes the field over a nanosecond timescale. Reconstruction of the magnetic field map from proton radiographs demonstrates that the field is advected by heat flow in advance of the plasma expansion with a velocity v_{N}=(6±2)×10^{5} m/s. Kinetic and extended magnetohydrodynamic simulations agree well in this regime due to the buildup of a magnetic transport barrier.

Abstract
BACKGROUND Given the role of systematic inflammation in cancer progression, lymphocyte-monocyte ratio (LMR) from peripheral blood has been suggested as a biomarker to assess the extent of inflammation in several solid malignancies. However, the role of LMR as a prognostic factor in head and neck cancer was unclear in several meta-analyses, and there is a paucity of literature including patients in North America. We performed an observational cohort study to evaluate the association of LMR with survival outcomes in North American patients with head and neck cancer. METHODS A single-institution, retrospective database was queried for patients with non-metastatic head and neck cancer who underwent definitive chemoradiation from June 2007 to April 2021 at the Roswell Park Comprehensive Cancer Center. Primary endpoints were overall survival (OS) and cancer-specific survival (CSS). The association of LMR with OS and CSS was examined using nonlinear Cox proportional hazard model using restricted cubic splines (RCS). Cox multivariable analysis (MVA) and Kaplan-Meier method were used to analyze OS and CSS. Pre-radiation LMR was then stratified into high and low based on its median value. Propensity scored matching was used to reduce the selection bias. RESULTS A total of 476 patients met our criteria. Median follow up was 45.3 months (interquartile range 22.8-74.0). The nonlinear Cox regression model showed that low LMR was associated with worse OS and CSS in a continuous fashion without plateau for both OS and CSS. On Cox MVA, higher LMR as a continuous variable was associated with improved OS (adjusted hazard ratio [aHR] 0,90, 95% confidence interval [CI] 0.82-0.99, p = 0.03) and CSS (aHR 0.83, 95% CI 0.72-0.95, p = 0.009). The median value of LMR was 3.8. After propensity score matching, a total of 186 pairs were matched. Lower LMR than 3.8 remained to be associated with worse OS (HR 1.59, 95% CI 1.12-2.26, p = 0.009) and CSS (HR 1.68, 95% CI 1.08-2.63, p = 0.02). CONCLUSION Low LMR, both as a continuous variable and dichotomized variable, was associated with worse OS and CSS. Further studies would be warranted to evaluate the role of such prognostic marker to tailor interventions.

Abstract
Introduction In humans, gait speed is a crucial component in geriatric evaluation since decreasing speed can be a harbinger of cognitive decline and dementia. Aging companion dogs can suffer from age-related mobility impairment, cognitive decline and dementia known as canine cognitive dysfunction syndrome. We hypothesized that there would be an association between gait speed and cognition in aging dogs. Methods We measured gait speed on and off leash in 46 adult and 49 senior dogs. Cognitive performance in senior dogs was assessed by means of the Canine Dementia Scale and a battery of cognitive tests. Results We demonstrated that dogs' food-motivated gait speed off leash is correlated with fractional lifespan and cognitive performance in dogs, particularly in the domains of attention and working memory. Discussion Food-motivated gait speed off leash represents a relatively easy variable to measure in clinical settings. Moreover, it proves to be a more effective indicator of age-related deterioration and cognitive decline than gait speed on leash.

Abstract
Importance Combined modality therapy, such as chemoradiotherapy, often results in significant morbidity among patients with head and neck cancer. Although the role of body mass index (BMI) varies based on cancer subtypes, its association with treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer remains unclear. Objective To evaluate the role of BMI in treatment response, tumor recurrence, and survival outcomes among patients with head and neck cancer undergoing chemoradiotherapy. Design, Setting, and Participants This retrospective, observational, single-institution cohort study conducted at a comprehensive cancer center included 445 patients with nonmetastatic head and neck cancer who underwent chemoradiotherapy from January 1, 2005, to January 31, 2021. Exposure Normal vs overweight or obese BMI. Main Outcomes and Measures Metabolic response after chemoradiotherapy, locoregional failure (LRF), distant failure (DF), overall survival (OS), and progression-free survival (PFS), with Bonferroni correction used to adjust for multiple comparisons and P < .025 being considered statistically significant. Results A total of 445 patients (373 men [83.8%]; median age, 61 years [IQR, 55-66 years]; 107 [24.0%] with normal BMI, 179 [40.2%] with overweight BMI, and 159 [35.7%] with obese BMI) were included for analysis. Median follow-up was 48.1 months (IQR, 24.7-74.9 months). On Cox proportional hazards regression multivariable analysis, only overweight BMI was associated with improved OS (5-year OS, 71.5% vs 58.4%; adjusted hazard ratio [AHR], 0.59 [95% CI, 0.39-0.91]; P = .02) and PFS (5-year PFS, 68.3% vs 50.8%; AHR, 0.51 [95% CI, 0.34-0.75]; P < .001). On logistic multivariable analysis, overweight BMI (91.6% vs 73.8%; adjusted odds ratio [AOR], 0.86 [95% CI, 0.80-0.93]; P < .001) and obese BMI (90.6% vs 73.8%; AOR, 0.89 [95% CI, 0.81-0.96]; P = .005) were associated with complete metabolic response on follow-up positron emission tomography-computed tomography after treatments. On Fine-Gray multivariable analysis, overweight BMI was associated with reduction in LRF (5-year LRF, 7.0% vs 25.9%; AHR, 0.30 [95% CI, 0.12-0.71]; P = .01), but not DF (5-year DF, 17.4% vs 21.5%; AHR, 0.92 [95% CI, 0.47-1.77]; P = .79). Obese BMI was not associated with LRF (5-year LRF, 10.4% vs 25.9%; AHR, 0.63 [95% CI, 0.29-1.37]; P = .24) or DF (5-year DF, 15.0% vs 21.5%; AHR, 0.70 [95% CI, 0.35-1.38]; P = .30). Conclusion In this cohort study of patients with head and neck cancer, when compared with normal BMI, overweight BMI was an independent factor favorably associated with complete response after treatments, OS, PFS, and LRF. Further investigations are warranted to improve understanding on the role of BMI among patients with head and neck cancer.

Abstract
Background: The role of prophylactic high-dose gabapentin for the management of oral mucositis during radiation therapy for head and neck squamous cell carcinoma (HNSCC) remains controversial. Methods: A retrospective cohort analysis was performed on primary HNSCC patients treated at our institution. Kruskal–Wallis and Fisher’s exact tests were used to compare the patients’ baseline characteristics. Multivariate competing risk and logistic regressions were performed to evaluate time to first opioid use and feeding tube placement. Results: In total, 480 consecutive HNSCC patients were included. Within this cohort, 186 patients received 3600 mg gabapentin, 182 received 300 to 3200 mg gabapentin, and 112 received no gabapentin. The time to first opioid use was greater in the 3600 mg group compared with the no gabapentin group (34.3 vs. 23.9 days, p < 0.001) and to the 300 to 3200 mg group (28.0 days, p < 0.001). The proportion of patients requiring opioids at any point during RT was lower in the 3600 mg gabapentin group compared with the no gabapentin group (31.8% vs. 60.1%, p < 0.001) and with the 300 to 3200 mg group (63.8%, p < 0.001). Conclusions: Prophylactic use of 3600 mg gabapentin was well tolerated, halved overall opioid use, and delayed the time to first opioid use during radiation therapy.

Abstract
Maintaining an active lifestyle is considered a hallmark of successful aging. Physical activity significantly reduces the risk of cognitive decline and Alzheimer's disease in humans. However, pain and lack of motivation are important barriers to exercise. Dogs are a remarkable model for translational studies in aging and cognition as they are prone to Canine Cognitive Dysfunction syndrome, which has many similarities with Alzheimer's disease. According to owner reports, changes in activity levels are characteristic of this syndrome, with decreased daytime activity, but also excessive pacing, especially at sleep time. We used physical activity monitors to record the activity of 27 senior dogs and evaluated the association between activity level and age, fractional lifespan, cognitive status measured by an owner questionnaire and cognitive tests. We also assessed the relationship between activity and joint/spinal pain, and the off/on leash gait speed ratio (a potential marker of gait speed reserve and motivation). We found that activity patterns in dogs are associated with fractional lifespan and working memory. Additionally, dogs with higher on/off leash gait speed are more active in the afternoon of weekdays. These results encourage future studies evaluating how physical activity can improve or delay cognitive impairment in senior dogs.

Abstract
OBJECTIVE To identify and assess the globally available valid, reliable and acceptable tools for assessing health research partnership outcomes and impacts. METHODS We searched Ovid MEDLINE, Embase, CINAHL Plus and PsycINFO from origin to 2 June 2021, without limits, using an a priori strategy and registered protocol. We screened citations independently and in duplicate, resolving discrepancies by consensus and retaining studies involving health research partnerships, the development, use and/or assessment of tools to evaluate partnership outcomes and impacts, and reporting empirical psychometric evidence. Study, tool, psychometric and pragmatic characteristics were abstracted using a hybrid approach, then synthesized using descriptive statistics and thematic analysis. Study quality was assessed using the quality of survey studies in psychology (Q-SSP) checklist. RESULTS From 56 123 total citations, we screened 36 027 citations, assessed 2784 full-text papers, abstracted data from 48 studies and one companion report, and identified 58 tools. Most tools comprised surveys, questionnaires and scales. Studies used cross-sectional or mixed-method/embedded survey designs and employed quantitative and mixed methods. Both studies and tools were conceptually well grounded, focusing mainly on outcomes, then process, and less frequently on impact measurement. Multiple forms of empirical validity and reliability evidence was present for most tools; however, psychometric characteristics were inconsistently assessed and reported. We identified a subset of studies (22) and accompanying tools distinguished by their empirical psychometric, pragmatic and study quality characteristics. While our review demonstrated psychometric and pragmatic improvements over previous reviews, challenges related to health research partnership assessment and the nascency of partnership science persist. CONCLUSION This systematic review identified multiple tools demonstrating empirical psychometric evidence, pragmatic strength and moderate study quality. Increased attention to psychometric and pragmatic requirements in tool development, testing and reporting is key to advancing health research partnership assessment and partnership science.

Abstract
Riedel's thyroiditis is a rare disease of chronic inflammation with fibrotic infiltration of the thyroid gland and its surrounding vital structures. Due to its low incidence, there are often delays in diagnosis as it is commonly mistaken for other thyroid diseases. We report the case of a 34-year-old female patient who presented with a firm, enlarged mass in the neck, compression symptoms, and hypothyroidism. Lab tests showed elevated A-TG (thyroglobulin antibodies) and A-TPO (thyroid peroxidase antibodies) levels. Based on the disease presentation and supporting lab findings, the patient was misdiagnosed with Hashimoto's thyroiditis and treated accordingly. Yet the patient's symptoms grew progressively worse. She was discovered to have severe tracheal compression and bilateral RLN (recurrent laryngeal nerve) palsy. Tracheotomy became a necessary surgical intervention after the development of respiratory failure, but this procedure was complicated by the development of an intraoperative pneumothorax. After an open biopsy, histology revealed Riedel's thyroiditis. A new treatment was introduced, with which the patient's condition improved. However, she continued to suffer from the open tracheocutaneous fistula left by the tracheostomy, which adversely affected her everyday life. A follow-up operation was performed to close the fistula. In this case report, we discuss the consequences of misdiagnosing the patient and delaying the appropriate treatment for her disease.

Abstract
Introduction Sleep is fundamental for cognitive homeostasis, especially in senior populations since clearance of amyloid beta (key in the pathophysiology of Alzheimer's disease) occurs during sleep. Some electroencephalographic characteristics of sleep and wakefulness have been considered a hallmark of dementia. Owners of dogs with canine cognitive dysfunction syndrome (a canine analog to Alzheimer's disease) report that their dogs suffer from difficulty sleeping. The aim of this study was to quantify age-related changes in the sleep-wakefulness cycle macrostructure and electroencephalographic features in senior dogs and to correlate them with their cognitive performance. Methods We performed polysomnographic recordings in 28 senior dogs during a 2 h afternoon nap. Percentage of time spent in wakefulness, drowsiness, NREM, and REM sleep, as well as latency to the three sleep states were calculated. Spectral power, coherence, and Lempel Ziv Complexity of the brain oscillations were estimated. Finally, cognitive performance was evaluated by means of the Canine Dementia Scale Questionnaire and a battery of cognitive tests. Correlations between age, cognitive performance and sleep-wakefulness cycle macrostructure and electroencephalographic features were calculated. Results Dogs with higher dementia scores and with worse performance in a problem-solving task spent less time in NREM and REM sleep. Additionally, quantitative electroencephalographic analyses showed differences in dogs associated with age or cognitive performance, some of them reflecting shallower sleep in more affected dogs. Discussion Polysomnographic recordings in dogs can detect sleep-wakefulness cycle changes associated with dementia. Further studies should evaluate polysomnography's potential clinical use to monitor the progression of canine cognitive dysfunction syndrome.

Abstract
OBJECTIVE To determine the outcomes in children with MIS-C receiving different immunomodulatory treatment. METHODS In this multicentric, retrospective cohort study, data regarding treatment and outcomes of children meeting the WHO case definition for MIS-C, were collected. The primary composite outcome was the requirement of vasoactive/inotropic support on day 2 or beyond or need of mechanical ventilation on day 2 or beyond after initiation of immunomodulatory treatment or death during hospitalization in the treatment groups. Logistic regression and propensity score matching analyses were used to compare the outcomes in different treatment arms based on the initial immunomodulation, i.e., IVIG alone, IVIG plus steroids, and steroids alone. RESULTS The data of 368 children (diagnosed between April 2020 and June 2021) meeting the WHO case definition for MIS-C, were analyzed. Of the 368 subjects, 28 received IVIG alone, 82 received steroids alone, 237 received IVIG and steroids, and 21 did not receive any immunomodulation. One hundred fifty-six (42.39%) children had the primary outcome. On logistic regression analysis, the treatment group was not associated with the primary outcome; only the children with shock at diagnosis had higher odds for the occurrence of the outcome [OR (95% CI): 11.4 (5.19-25.0), p < 0.001]. On propensity score matching analysis, the primary outcome was comparable in steroid (n = 45), and IVIG plus steroid (n = 84) groups (p = 0.515). CONCLUSION While no significant difference was observed in the frequency of occurrence of the primary outcome in different treatment groups, data from adequately powered RCTs are required for definitive recommendations.

Abstract
IMPORTANCE After 10 pack-years of smoking was initially established as a threshold for risk stratification, subsequent clinical trials incorporated it to identify candidates for treatment deintensification. However, several recent studies were unable to validate this threshold externally, and the threshold for smoking exposure remains unclear. OBJECTIVE To estimate the threshold of pack-years of smoking associated with survival and tumor recurrence among patients with head and neck cancer. DESIGN, SETTING, AND PARTICIPANTS This single-institution, cohort study included patients with nonmetastatic head and neck cancer receiving chemoradiation from January 2005 to April 2021. Data were analyzed from January to April 2022. EXPOSURES Heavy vs light smoking using 22 pack-years as a threshold based on maximizing log-rank test statistic. MAIN OUTCOMES AND MEASURES Overall survival (OS), progression-free survival (PFS), locoregional failure (LRF), and distant failure (DF). RESULTS A total of 518 patients (427 male [82.4%]; median [IQR] age, 61 [55-66] years) were included. Median (IQR) follow-up was 44.1 (22.3-72.8) months. A nonlinear Cox regression model using restricted cubic splines showed continuous worsening of OS and PFS outcomes as pack-years of smoking increased. The threshold of pack-years to estimate OS and PFS was 22. Cox multivariable analysis (MVA) showed that more than 22 pack-years was associated with worse OS (adjusted hazard ratio [aHR] 1.57; 95% CI, 1.11-2.22; P = .01) and PFS (aHR, 1.38; 95% CI, 1.00-1.89; P = .048). On Fine-Gray MVA, heavy smokers were associated with DF (aHR, 1.71; 95% CI, 1.02-2.88; P = .04), but not LRF (aHR, 1.07; 95% CI, 0.61-1.87; P = .82). When 10 pack-years of smoking were used as a threshold, there was no association for OS (aHR, 1.23; 95% CI, 0.83-1.81; P = .30), PFS (aHR, 1.11; 95% CI, 0.78-1.57; P = .56), LRF (aHR, 1.19; 95% CI, 0.64-2.21; P = .58), and DF (aHR, 1.45; 95% CI, 0.82-2.56; P = .20). Current smoking was associated with worse OS and PFS only among human papillomavirus (HPV)-positive tumors (OS: aHR, 2.81; 95% CI, 1.26-6.29; P = .01; PFS: aHR, 2.51; 95% CI, 1.22-5.14; P = .01). CONCLUSIONS AND RELEVANCE In this cohort study of patients treated with definitive chemoradiation, 22 pack-years of smoking was associated with survival and distant metastasis outcomes. Current smoking status was associated with adverse outcomes only among patients with HPV-associated head and neck cancer.

Abstract
The present study compares the in vitro effects of nanoparticles loaded pentamidine drug and conventional pentamidine on Leishmania tropica. Herein, pentamidine-loaded chitosan nanoparticles (PTN-CNPs) have been synthesized through an ionic gelation method with sodium tripolyphosphate (TPP). Next, the physical characteristics of PTN-CNPs were determined through the surface texture, zeta potential, in vitro drug release, drug loading content (DLC), and encapsulation efficacy (EE) and compared its efficacy with free pentamidine (PTN) drug against promastigotes and axenic amastigotes forms of L. tropica in vitro. The PTN-CNPs displayed a spherical shape having a size of 88 nm, an almost negative surface charge (-3.09 mV), EE for PTN entrapment of 86%, and in vitro drug release of 92% after 36 h. In vitro antileishmanial activity of PTN-CNPs and free PTN was performed against Leishmania tropica KWH23 promastigote and axenic amastigote using 3-(4, 5- dimethylthiazol-2-yl)-2, 5-diphenyletetrazolium bromide (MTT) assay. It was observed that the effect of PTN-CNPs and free PTN on both forms of the parasite was dose and time dependent. Free PTN presented low efficacy even at higher dose (40 µg/ml) with 25.6 ± 1.3 and 26.5 ±1.4 mean viability rate of the promastigotes and axenic amastigotes, respectively after 72 hrs incubation. While PTN-CNPs showed strong antileishmanial effects on both forms of parasite with 16 ± 0.4 and 19 ± 0.7 mean viability rate at the same higher concentration (40 µg/ml) after 72 hrs incubation. Half maximal inhibitory concentration (IC50) values of PTN-CNPs toward promastigotes and amastigotes were obtained as 0.1375 µg/ml and 0.1910 µg/ml, respectively. In conclusion, PTN-CNPs effectively inhibited both forms of the L. tropica; however, its effect was more salient on promastigotes. This data indicates that the PTN-CNPs act as a target drug delivery system. However, further research is needed to support its efficacy in animal and human CL.

Abstract
Shock ignition enables high gain at low implosion velocity, reducing ablative Rayleigh-Taylor instability growth, which can degrade conventional direct drive. With this method, driving a strong shock requires high laser power and intensity, resulting in inefficiencies in the drive and the generation of hot electrons that can preheat the fuel. A new "shock-augmented ignition" pulse shape is described that, by preconditioning the ablation plasma before launching a strong shock, enables the shock ignition of thermonuclear fuel, but importantly, with substantially reduced laser power and intensity requirements. The reduced intensity requirement with respect to shock ignition limits laser-plasma instabilities, such as stimulated Raman and Brillouin scatter, reducing the risk of hot-electron preheat and restoring the laser coupling advantages of conventional direct drive. Simulations indicate that, due to the reduced power requirements, high gain (∼100) ignition of large-scale direct drive implosions (outer radius ∼1750 μm, deuterium-tritium ice thickness ∼165 μm) may be possible within the power and energy limits of existing facilities such as the National Ignition Facility. Moreover, this concept extends to indirect drive implosions, which exhibit substantial yield increases at reduced implosion velocity. Shock-augmented ignition expands the viable design space of laser inertial fusion.

Abstract
Abstract
Background
Heparin administered after Coronary Artery Bypass Grafting (CABG) can cause Heparin induced thrombocytopenia (HIT) leading to bleeding or thromboembolic complications. Despite its low incidence, HIT can lead to increased morbidity and in-hospital mortality.
Purpose
To study the incidence and periprocedural outcomes of HIT in On-pump vs Off-pump CABG patients.
Methods
This is a retrospective observational study involving index hospitalizations for CABG between January 1 2016–December 31 2019 from the National Inpatient Sample, the largest all-payer public database of hospital care data in the United States. Our study population included discharged adult patients (≥18 years) hospitalised for CABG using ICD-10 codes (validated in previous studies). Confounders were adjusted using Multivariable Regression Analysis.
Results
During 2016–2019, there were 100,715 principal hospitalizations for On-pump and 25,956 for Off-pump CABG. Mean age was 74.6±13.2 years. The incidence of HIT in the On-pump cohort was 0.33% (n=333) and 0.33% (n=85) in the Off-pump cohort. The On-pump cohort had 76% (n=76,543) males, 24% (n=24172) females (p<0.0001) and the Off-pump cohort had 74.5% (n=19337) males, 24.5% (n=6359) females (p<0.001). The On-pump cohort had 78.2% Whites, 7.1% Blacks, 7.7% Hispanics, and 7% other races, while the Off-pump cohort had 76.9% Whites, 7.8% blacks, 8.9% Hispanics and 6.4% other races. A total of 42.9% hospitalizations in the On-pump cohort had a Charlson Comorbidity Index (CCI) of three or higher and it was 43.5% hospitalizations in the Off-pump cohort. In-hospital mortality in the On-pump cohort was 1.6% and 2% in the Off-pump cohort.
Compared to the non-HIT cohort, On-pump HIT cohort had more females (31.2% vs 24%, p=0.02), were older (mean age: 67.2 years vs 65.7 years; p=0.006), had higher CCI of three or higher (65.8% vs 42.8%, p<0.001), longer LOS (22.2 days vs 9.2 days, p<0.001) with higher in-hospital mortality (13.5% vs 1.5%, p<0.001). Multivariate regression analysis showed HIT cohort had higher odds of in-hospital mortality than non-HIT cohort (aOR: 8; 95% CI: 5.7, 11.2; p<0.001) after controlling for age, sex, race, hospital region and status, income, insurance status and CCI.
The Off-pump HIT cohort had similar incidence of females (26% vs 27%, p=0.710), were older (mean age: 68 years vs 65.8 years; p=0.045), had higher CCI of three or higher (65.9% vs 43.5%, p<0.001), had longer LOS (22.9 days vs 9.4 days, p<0.001) with higher in-hospital mortality (10.6% vs 2%, p<0.001) compared to the non-HIT cohort. Multivariate regression analysis showed HIT cohort had higher odds of in-hospital mortality than non-HIT cohort (aOR: 4.7; 95% CI: 2.3, 9.5; p<0.001) after controlling for age, sex, race, hospital region and status, income, insurance status and CCI.
Conclusion
Our study observed that in-hospital mortality in patients with HIT was significantly high compared to patients without HIT after undergoing On-pump or Off-pump CABG.

Abstract
Abstract
Background
Ventricular fibrillation (VF) is common in acute ST segment elevation myocardial infarction (STEMI) and is associated with increased in-hospital mortality rate.
Purpose
We sought to investigate the association between VF and artery involved in STEMI
Methods
This is a retrospective observational study of hospitalizations between January 1, 2016 and December 31, 2019, using the National Inpatient Sample (NIS), the largest all-payer public database of hospital care in the United States.
Results
A total of 138,201 patients were primarily hospitalized for STEMI from 2016 to 2019. Among them 12,318 had right coronary artery (RCA) lesions, 427 had left main (LM) lesions, 2381 had left circumflex (LCx) lesions and 12,765 had left anterior descending (LAD) lesions. Mean age of patients with VF and STEMI was 62 years and that with RCA (63 years), LM (65 years), LCx (62 years), LAD (60 years), p<0.001. Females were 30.5% (n=42,231) among all STEMI group and 29.8% (n=3672) RCA, 29% (n=124) LM, 27.4%(n=653) LCx and 28.6%(n=3645) LAD, p<0.001. In-hospital mortality for all patients with STEMI was 7.9%. The in-hospital mortality associated with STEMI there was 5%, 23.4%, 6.6%, 7.1%, (p<0.001) for RCA, LM, LCx and LAD respectively. The incidence of VF among all patients with STEMI was 8.3% (n=11425) and for LM, LAD, LCX, and RCA was 12.9%, 10.7%, 9.2% and 7.9% (p<0.001). Mean hospital length of stay for VF with RCA (6.2 days), LM (5.5 days), LCx (6.9 days) and LAD (7.4 days). After adjusting for age, gender, race, income, comorbidities, hospital teaching status, region and year, patients with STEMI who had VF had higher odds of mortality (aOR 6.4, 95% CI, 6.1 to 6.8; P<0.001). The highest likelihood of mortality observed in patients with VF who had and LCx STEMI (aOR 7.9, CI 95%, 5 to 12.4; p<0.001) followed by RCA STEMI (aOR 7.4, 95% CI 6 to 9.1; p<0.001), and LM STEMI (aOR 6.1, 95% 3.1 to 12; p<0.001).
Conclusion
Highest in-hospital mortality was observed in patients with STEMI who had VF in LCx, followed by RCA and LM. There was higher occurrence of VF in STEMI involving LM.

Abstract
Introduction Injectable medicines are increasingly used to manage risk factors for cardiovascular (CV) events, such as PCSK-9 inhibitors in dyslipidaemia and GLP-1 agonists in diabetes. However, there is a paucity of data around the administrative and clinical practicalities when using these injectables, and limited information on patient and healthcare professionals' perceptions. Purpose To identify the facilitators and barriers on the use of injectable therapies with CV benefits by undertaking interviews with patients, caregivers and healthcare professionals (HCPs). Methods Interviews were conducted via telephone and using MS Teams due to Covid-19 restrictions in the United Kingdom (London and Leeds) and Italy (Rome and Milan) in 2021. Coding was undertaken using NVivo and thematic analysis performed. Results A total of 56 patients were interviewed: 30 in the U.K. (mean age 66 yrs, 60% male) and 26 patients in Italy (mean age 63 yrs, 80% male) and 11 caregivers (mean age 59 yrs, 73% female). A total of 38 HCPs were interviewed, 19 in each country and composed of physicians (n=18), pharmacists (n=10), nurses (n=9) and pharmacy technician (n=1). Three distinct themes were identified: (i) Organisational and governance issues - relating to prescribing restrictions and availability of the drugs locally (PCSK9i are initiated and supplied from hospitals) and lack of communication between hospital and primary care setting; (ii) Clinical issues around HCPs' skills and experience - including: lack of experience with these injectables, lack of time to provide education to patients and caregivers, therapeutic inertia (HCPs not adopting a change in practice despite the evidence or due to bureaucratic restrictions) as well as lack of knowledge on long-term effects, and finally (iii) Patient-related issues - relating to behaviours and beliefs such as reluctance about using injectable therapies, and lack of education about these injectables in terms of indications/clinical benefits for use. Despite some differences in the prescribing of these injectables in the two countries, the analysis captured similar facilitators and barriers. Facilitators included prior use of injectables (e.g. insulin), and the ability to reach a clinical target of lower cholesterol by having just a “one shot”. HCPs stated that access to rapid pathology tests would aid uptake of injectables with CV benefit as well as having educational tools on these injectables in practice. Conclusion This qualitative study identified barriers to initiation, continuation, and adherence with injectable therapies with CV benefits but also highlighted areas where changes can be made especially around education and support for patients and HCPs.

Abstract
Abstract
Background
Statins are cornerstone in the management of atherosclerotic cardiovascular disease. If a patient has experienced clinically significant adverse drug reactions (ADRs), representing an unacceptable risk or may result in adherence issues, we would consider them intolerant. The prevalence is lower in randomised trials than cohort observational studies, 5% vs. 17%.
Purpose
To assess how many people we reviewed in clinic were able to be re-challenged and successfully continued on a statin, free from side effects.
Methods
Over 6 months we reviewed all patients referred to our innovative clinic for lipid optimisation labelled as “statin intolerant”. Initially, as per our protocol, we adopted a person-centred approach and explored this label (actual vs. potential concerns, any previous issues, symptoms experienced and timings, statins tried (if any), and patient's feelings on re-challenge). A statin re-challenge was offered if not contraindicated. If agreed, based on shared-decision making, we offered patients a once weekly statin (usually rosuvastatin 5mg) with a clear self-management plan to up/down-titrate frequency and dose, until they identify a tolerated regimen. We measured LDL-C at baseline and every 3 months thereafter until satisfactory.
Results
Of 207 patients referred 152 (73%) were labelled as “statin intolerant”. Average age was 62 (±11), 51% females. 78% for secondary prevention and 37% had familial hypercholesterolaemia. The average baseline LDL-C was 4.4mmol/L. 108 (71%) qualified for PCSK9 inhibitors therapy (PCSK9i) as per UK NICE guidance.
The top 3 reported ADRs were musculoskeletal side effects (48%), GI upsets (13%) and deranged LFTs (7%).
25 (58%) of those “intolerant” who did not qualify for PCSK9i attempted a re-challenge with statins vs. 44 (41%) among those who qualified.
Of the 69 patients, who accepted a re-challenge, 43 (62%) were successfully restarted on a statin. At an average of 14 months post re-challenge, LDL-C (available for >80% of the sample) was reduced by an average of 31% in those not on PCSK9i, compared to a 62% reduction (sustained over an average of 40 months) in those on combination therapy with PCSK9i.
The top 3 rosuvastatin regimens established were 5mg OD (29%), 5mg weekly (24%) and 10mg OD (15%). Approximately 80% of patients were on rosuvastatin, and the rest accepted atorvastatin, pravastatin or simvastatin.
There was no attempt to re-challenge in 77 (51%) patients, mostly due to choice (45%) or statins re-challenged prior to referral (44%). We stopped statins in 6 cases due to intolerable ADRs.
Conclusion(s)
By using a person-centred approach, and a variety of strategies to tackle “statin intolerance” we have successfully re-established over 60% of patients with very high CVD risk on statins. While patients who qualified for PCSK9i therapy were less likely to consider re-challenge with statins (41% v 58%), combination lipid-lowering therapies produced better reduction in LDL-C.

Abstract
OBJECTIVES We sought to define the optimal threshold for anemia in North American head and neck cancer patients and evaluate its role as a prognostic biomarker. MATERIALS AND METHODS A single-institution database was queried for patients with head and neck cancer who underwent chemoradiation from January 2005 to April 2021. An optimal threshold of hemoglobin (Hgb) level was defined based on maximum log-rank test statistic. Cox multivariable analysis (MVA), Kaplan-Meier, and propensity score matching were performed to evaluate treatment outcomes. RESULTS A total of 496 patients were identified. Threshold for Hgb was determined to be 11.4 for both overall survival (OS) and progression-free survival (PFS). Low Hgb was associated with worse OS (adjusted hazards ratio [aHR] 2.41, 95 % confidence interval [CI] 1.53-3.80, p < 0.001) and PFS (aHR 2.01, 95 % CI 1.30-3.11, p = 0.002). Similar findings were observed among 39 matched pairs for OS (5-year OS 22.3 % vs 49.0 %; HR 2.22, 95 % CI 1.23-4.03, p = 0.008) and PFS (5-year PFS 24.3 % vs 39.1 %; HR 1.78, 95 % CI 1.02-3.12, p = 0.04). Among those with HPV-negative tumors, low Hgb was associated with worse OS (aHR 13.90, 95 % CI 4.66-41.44, p < 0.001) and PFS (aHR 5.24, 95 % CI 2.09-13.18, p < 0.001). However, among those with HPV-positive tumors, low Hgb was not associated with both OS (aHR 1.75, 95 % CI 0.60-5.09, p = 0.31) and PFS (aHR 1.13, 95 % CI 0.41-3.14, p = 0.82). CONCLUSION AND RELEVANCE Low Hgb below 11.4 was an independent adverse prognostic factor for worse survival. It was also prognostic among patients with HPV-negative tumors, but not for HPV-positive tumors.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
INTRODUCTION Chyle leak is an uncommon yet potentially fatal complication of oesophagectomy for oesophageal cancer. The management of chyle leak is a debated, controversial topic and to date there is no standardised approach or validated algorithm for its management. This review aims to summarise current treatment algorithms for chyle leak post-oesophagectomy and their outcomes. METHODS A systematic search of Embase, MEDLINE, UpToDate and Cochrane was conducted to identify studies reporting on the management of chyle leak following oesophagectomy for oesophageal cancer. Data on interventional success rate and mortality are reported. FINDINGS Twenty-one studies met the inclusion criteria including over 23,254 oesophagectomies and identifying 838 chyle leaks (incidence <3.6%). The majority of cases were initially managed conservatively (95.3%), with a failure rate of 50.4%. Immediate surgical or radiological management resolved chylothorax in the majority of cases (97.3%), however the numbers were small. Death occurred in 54 cases (6.6%), all of whom underwent conservative management initially. CONCLUSIONS Owing to the heterogeneity of treatment algorithms, timings and indications for interventions, the optimal strategy for managing chyle leak remains unclear. This review has identified an unmet need for prospective multicentre studies assessing the efficacy of predefined algorithms.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Introduction
Mood disorders are common psychiatric illnesses with major disability and mortality and it is estimated that 8% to 20% of the population experience a depressive episode at some point in their lives.
Objectives
To find out the prevalence of cognitive impairment among patients with Mood Disorders i.e, Major Depressive Disorder
(MDD) and Bipolar Mood Disorder (BMD), etc. and to find out the status of cognitive impairment with clinical variables of Mood Disorders.
Methods
This was a descriptive cross-sectional study conducted among the patients attending both the inpatient and outpatient departments of the National Institute of Mental Health, Dhaka. The duration of the study was fourteen months starting from July 2011 to September 2012. A total of one hundred and thirty-three (n=133) patients who fulfilled the inclusion-exclusion criteria were selected.
Results
The mean age of onset of mood disorder was 30.1± 10.7years.60.2% were male and 39.8% were female respondents. Cognitive impairment was found among 43.6% of the respondents. A substantial proportion of the study population was found to have cognitive impairment. In this study, the cognitive status of the respondents was not associated with the duration of illness (p>0.5).
Conclusions
So assessment of cognitive status should be an essential part of the management of this group of people.
Disclosure
No significant relationships.

Abstract
Introduction COVID 19 has led to dramatic changes in the lives of people leading to an increase in stress and anxiety. Music intervention is a non-medicated method for relieving anxiety. This current study aims to understand whether music can be effectively used to alleviate anxiety in admitted COVID-19 patients. Objectives To study the effect of music on anxiety in patients admitted for COVID-19 in a tertiary care hospital in New Delhi Methods 34 patients (17 females &17 males) were randomly divided into two groups, a control (N=17) and a music group (N=17). Vitals of all the patients were noted. Patients of the music group were asked to listen to relaxing instrumental for 30 minutes, while patients of the control group were asked to relax for 30 minutes. Vitals of all the patients were noted again. Patients were asked to fill State Trait Anxiety Inventory (STAI) before and after intervention. Results The post-intervention mean scores of STAI after the music session were lower in the music group than the control group [95.06 (SD 8.5)) versus 102.37 (SD 10.3)]. The differences in mean values of pre- to post-intervention changes between both groups after music session were statistically significant. Conclusions Our findings suggest that listening to music lowers anxiety. As music is non- invasive and free of side-effects we recommend that music intervention service should be used to improve health care quality. Disclosure No significant relationships.
