Abstract
INTRODUCTION Flexible nasendoscopy (FNE) is the principal assessment method for vocal cord movement. Because the procedure is inherently subjective it may not be possible for clinicians to grade the degree of vocal cord movement reliably. The aim of this study was to assess the accuracy and consistency of grading vocal cord movement as viewed via FNE. METHODS Thirty FNE videos, without sound or clinical information, were assessed by six consultant head and neck surgeons. The surgeons were asked to assess and grade right and left vocal cord movement independently, based on a five-category scale. This process was repeated three times on separate occasions. Agreement and reliability were assessed. RESULTS Mean overall observed inter-rater agreement was 67.7% (sd 1.9) with the five-category scale, increasing to 91.4% (sd 1.9) when a three-category scale was derived. Mean overall observed intra-rater agreement was 78.3% (sd 9.7) for five categories, increasing to 93.1% (sd 3.3) for three categories. Discriminating vocal cord motion was less reliable using the five-category scale (k = 0.52) than with the three-category scale (k = 0.68). CONCLUSIONS This study demonstrates quantitatively that it is challenging to accurately and consistently grade subtle differences in vocal cord movement, as proven by the reduced agreement and reliability when using a five-point scale instead of a three-point scale. The study highlights the need for an objective measure to help in the assessment of vocal cord movement.

Abstract
INTRODUCTION The 31-day target in urgent suspicion of cancer (USOC) referrals fast-tracks patients through the cancer pathway. Local anaesthetic (LA) biopsy can be performed during an outpatient clinic and may improve pathway times. The aim of this study was to compare LA biopsy in head and neck USOC referrals with the traditional general anaesthetic (GA) pathway. METHODS This was a retrospective cohort study of USOC referrals to the NHS Greater Glasgow and Clyde head and neck multidisciplinary team between 1 June 2018 and 28 December 2020, and compared pathway times in LA and GA biopsies. RESULTS The mean number of days from clinic to biopsy was 4.4 in the LA group and 28.0 in the GA group. This was significantly faster in the LA biopsy group (p < 0.05). The overall pathway time in the LA and GA biopsy groups was 35.7 and 61.5 days, respectively, and was significantly faster in LA biopsy group (p < 0.05). CONCLUSIONS The LA cohort had significantly faster pathway times compared with GA biopsy. LA biopsy requires careful patient selection, but is an effective alternative to GA biopsy in the appropriate patient group.

Abstract
INTRODUCTION The majority of head and neck cancer referrals are received through primary care. A proportion of cancer referrals are received through secondary care specialties. Local delivery plan (LDP) targets in Scotland for cancer investigation are set at 31 days for diagnosis and 62 days to start treatment. The aim was to audit referrals made through non-primary care pathways compared with the standard primary care pathways against LDP targets. METHODS New head and neck cancer patients between 1 January 2014 and 1 January 2019 were included. Pathway points were recorded between referral to outpatient clinic, time to multidisciplinary team discussion (MDT) and finally MDT to treatment. RESULTS 1,276 new patient referrals were received over a 5-year period. Of these, 136 (10%) were referred via non-primary care pathways. The mean time for urgent suspicion of cancer (USoC) referrals to start treatment was 77 days (15 days over target) and for outpatient secondary care referrals was 102 days (40 days over target) (p<0.05). When treatment intent was considered, 841/1,131 (75%) of patients referred via primary care were treated curatively compared with 49/99 (49%) (p<0.05) of patients referred through the secondary outpatient pathway. CONCLUSION Patients with head and neck cancer referred from other outpatient specialties face delays commencing cancer treatment and are also associated with a greater likelihood of being treated with palliative intent.

Abstract
We describe the MalariaGEN Pf7 data resource, the seventh release of Plasmodium falciparum genome variation data from the MalariaGEN network. It comprises over 20,000 samples from 82 partner studies in 33 countries, including several malaria endemic regions that were previously underrepresented. For the first time we include dried blood spot samples that were sequenced after selective whole genome amplification, necessitating new methods to genotype copy number variations. We identify a large number of newly emerging crt mutations in parts of Southeast Asia, and show examples of heterogeneities in patterns of drug resistance within Africa and within the Indian subcontinent. We describe the profile of variations in the C-terminal of the csp gene and relate this to the sequence used in the RTS,S and R21 malaria vaccines. Pf7 provides high-quality data on genotype calls for 6 million SNPs and short indels, analysis of large deletions that cause failure of rapid diagnostic tests, and systematic characterisation of six major drug resistance loci, all of which can be freely downloaded from the MalariaGEN website.

Abstract
Abstract
Introduction
Many factors influence age of presentation with and survival following ST-segment myocardial infarction (STEMI). These include age, mode of, and time-delay to emergency treatment, diabetes and smoking. We sought to assess whether overall social deprivation status is associated with age of presentation and mortality following STEMI patients treated with primary PCI.
Methods
All patients treated emergently for STEMI in a large Northern Irish tertiary hospital from 2013 – 2017 were reviewed. Social deprivation is determined as a composite score relating to income, crime etc, and assigned to small geographical regions by the Northern Ireland Statistics and Research Agency. Deprivation score was assigned to patients based on their postcode. The database was ranked by social deprivation score and divided in to quintiles. The most (Grp 1) and least (Grp 5) deprived quintiles were compared. Mortality was determined from a national electronic health record.

1,192 patients were included in the analysis. Mean follow up was 52.5 months (SD 15.6), minimum follow up was 35.6 months. There was no difference in gender: 70.1% male in Grp 1 vs 75.2% male in Grp 5 (p=0.68); no difference in ECG to balloon time: mean 89.9mins (95% CI 84.9–94.9) Grp 1 vs 90.5mins (95% CI 86.2–94.9) Grp 5 (p=0.86). The more deprived group was younger: mean age 60.6 (95% CI 59.5–61.6) vs 65.2 (95% CI 64.2–66.3) (p<0.000). Crude survival measured by Log-rank test was the same between the groups (p=0.52). Following Cox-regression adjustment for age, survival was longer in the least deprived group (p=0.042).
Conclusion
Social deprivation is associated with both a younger age of presentation with, and a higher mortality following STEMI. This is important variable is often overlooked in medical literature and should be further studied.

Abstract
This national professional society guidance lays out operational and ethical principles for decision-making during a pandemic, in the immediate context of COVID-19 in the early 2020 surge iteration but with potential ongoing relevance. It identifies the different phases of a pandemic and the implications for capacity and mutual aid within a national healthcare system, and introduces a revised CRITCON-PANDEMIC framework for shared operational responsibilities and clinical decision-making. Usual legal and ethical frameworks should continue to apply while capacity and mutual aid are available (CRITCON-PANDEMIC levels 0-3); clinicians should focus on current clinical needs and should not treat patients differently because of anticipated future pressures. In conditions of resource limitation (CRITCON-PANDEMIC 4), a structured and equitable approach is necessary and an objective Decision Support Aid is proposed. In producing this guidance, we emphasise that all patients must be treated with respect and without discrimination, because everyone is of equal value. The guidance has been put together with input from patient and public groups and aims to provide standards that are fair to everyone. We acknowledge that COVID-19 is a new disease with a partial and evolving knowledge base, and aim to provide an objective clinical decision-making framework based on the best available information. It is recognised that a factual assessment of likely benefit may take into account age, frailty and comorbidities, but the guidance emphasises that every assessment must be individualised on a balanced, case by case, basis and may inform clinical judgement but not replace it. The effects of a comorbidity on someone's ability to benefit from critical care should be individually assessed. Measures of frailty should be used with care, and should not disadvantage those with stable disability.

Abstract
In this study, we used bi-temporal airborne lidar data to compare changes in vegetation height proximal to anthropogenic disturbances in the Oil Sands Region of Alberta, Canada. We hypothesize that relatively low-impact disturbances such as seismic lines will increase the fragmentation of wetlands, resulting in shrub growth. Bi-temporal lidar data collected circa 2008 and 2018 were used to identify correspondence between the density of anthropogenic disturbances, wetland shape complexity and changes in vegetation height within >1800 wetlands near Fort McKay, Alberta, Canada. We found that up to 50% of wetlands were disturbed by anthropogenic disturbance in some parts of the region, with the highest proportional disturbance occurring within fens. Areas of dense anthropogenic disturbance in bogs resulted in increased growth and expansion of shrubs, while we found the opposite to occur in fens and swamps during the 10-year period. Up to 30% of bogs had increased shrubification, while shrub changes in fens and swamps varied depending on density of disturbance and did not necessarily correspond with shrub growth. As wetland shapes became increasingly elongated, the prevalence of shrubs declined between the two time periods, which may be associated with hydrological drivers (e.g. elongated may indicate surface and ground-water discharge influences). The results of this study indicate that linear disturbances such as seismic lines, considered to have relatively minimal impacts on ecosystems, can impact proximal wetland shape, fragmentation and vegetation community changes, especially in bogs.

Abstract
The aims of this study were to externally validate the OroGrams (oropharyngeal cancer survival calculator) nomogram in a Scottish cohort with high endemic smoking rates, and to compare survival rates with the original validation cohort. A retrospective cohort study in Greater Glasgow and Clyde ENT and OMFS departments was performed to investigate survival outcomes of patients with oropharyngeal squamous cell carcinoma (OPSCC) from January 2012 - December 2017. The main outcome measures were progression-free (PFS) and overall survival (OS), and Kaplan Meier curves. The predictive accuracy of OroGrams was investigated for survival probabilities at one, three, and five years. Smoking and HPV-negative cancer rates were significantly higher in Scottish patients than in the UK consortium cohort. A greater proportion of Scottish patients had advanced UICC8 stages. PFS in patients with HPV-negative cancer appeared better in the Scottish cohort than in the original cohort. Calculated mean standardised Brier scores for PFS and OS were below 0.2 at all three follow-up points, suggesting good overall prognostic accuracy, but there was wide variation between predictive accuracy in individual patients. OroGrams shows prognostic accuracy at one-year follow up in Scotland. The accuracy decreases with longer follow-up periods.

Abstract
INTRODUCTION Tracheostomy is a common surgical procedure used to create a secure airway in patients, now performed by a variety of specialties, with a notable rise in critical care environments. It is unclear whether this rise is seen in units with large head and neck surgery departments, and how practice in such units compares with the rest of the UK. METHODS A three-year retrospective audit was carried out between anaesthetic, surgical and critical care departments. All tracheostomy procedures were recorded anonymously. RESULTS A total of 523 tracheostomies were performed, 66% of which were in men. The mean patient age was 60 years. The majority (83%) were elective, performed for various indications, while the remaining 17% were emergency tracheostomies performed for pending airway obstruction. A fifth of the tracheostomies were percutaneous procedures. Most emergency tracheostomies (78%) were performed by otolaryngology. Three cricothyroidotomies were performed within critical care and theatres. Complications related to tracheostomy occurred in 47 cases (9%), most commonly lower respiratory tract infection. The mean time to decannulation was 12.8 days. CONCLUSIONS This paper discusses the findings of a comprehensive, multispecialty audit of tracheostomy experience in a large health board, with over 150 tracheostomies performed annually. Elective cases form the majority although there is a significant case series of emergency tracheostomies performed for a range of pathologies. Around a quarter of those requiring tracheostomy ultimately died, mostly as a result of advanced cancer.

Abstract
We present two prescriptions for broadband ($ {\sim} 77 - 252\;{\rm GHz} $), millimeter-wave antireflection coatings for cryogenic, sintered polycrystalline aluminum oxide optics: one for large-format (700 mm diameter) planar and plano-convex elements, the other for densely packed arrays of quasi-optical elements-in our case, 5 mm diameter half-spheres (called "lenslets"). The coatings comprise three layers of commercially available, polytetrafluoroethylene-based, dielectric sheet material. The lenslet coating is molded to fit the 150 mm diameter arrays directly, while the large-diameter lenses are coated using a tiled approach. We review the fabrication processes for both prescriptions, then discuss laboratory measurements of their transmittance and reflectance. In addition, we present the inferred refractive indices and loss tangents for the coating materials and the aluminum oxide substrate. We find that at 150 GHz and 300 K the large-format coating sample achieves $ (97 \pm 2)\% $ transmittance, and the lenslet coating sample achieves $ (94 \pm 3)\% $ transmittance.

Abstract
AIM To determine the accuracy of contrast-enhanced computed tomography (CECT) for nodal extracapsular spread (ECS) and identify predictive radiological signs and clinicopathological features for ECS in unknown-primary head and neck squamous cell cancer (UPHNSCC). MATERIALS AND METHODS The CECT imaging of patients who underwent primary neck dissection for UPHNSCC during 2011-2015 was analysed. The largest pathological-looking node at each radiologically involved level was evaluated in consensus by two head and neck radiologists. Parameters included longest diameter, margin sharpness, haziness in adjacent fat, necrosis, and loss of fat plane with adjacent structures. Independent assessment was also made regarding the presence/absence of ECS. Findings and clinicopathological parameters were correlated with histopathology. RESULTS Thirty-one patients with 39 neck levels had metastatic nodal involvement determined on CECT. Confirmed ECS was found at 26 levels in 23 patients. Sensitivity of radiological assessment for ECS by nodal level was 81-85% (95% confidence interval [CI]=65-93%) and specificity 46-54% (95% CI=19-81%); kappa 0.87. On univariate analysis based on the largest involved node per patient, longest diameter being ≥30 mm (p=0.007), haziness in adjacent fat (p=0.023), increasing age (p=0.006), and more advanced pathological nodal status (p=0.027) were statistically significantly associated with ECS. Haziness and increasing age were independent predictors on multivariate analysis (odds ratio [OR]=26.4 and 1.24). CONCLUSION Expert assessment of ECS on CECT had good sensitivity with excellent interobserver agreement. A longest nodal diameter of ≥30 mm, haziness in the surrounding fat on CECT, advanced pathological nodal status, and advancing patient age were significantly associated with ECS in UPHNSCC patients, findings not previously reported.

Abstract
We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by rotating the cluster-centered Stokes QU map cutouts along the direction of the locally measured background CMB polarization gradient. Using data from the SPTpol 500 deg^{2} survey at the locations of roughly 18 000 clusters with richness λ≥10 from the Dark Energy Survey (DES) Year-3 full galaxy cluster catalog, we detect lensing at 4.8σ. The mean stacked mass of the selected sample is found to be (1.43±0.40)×10^{14}M_{⊙} which is in good agreement with optical weak lensing based estimates using DES data and CMB-lensing based estimates using SPTpol temperature data. This measurement is a key first step for cluster cosmology with future low-noise CMB surveys, like CMB-S4, for which CMB polarization will be the primary channel for cluster lensing measurements.

Abstract
INTRODUCTION Primary care patients with a suspected head and neck cancer are referred through the urgent suspicion of cancer referral pathway. Rates of cancer detection through this pathway are low. Evidence surrounding the pathway of these patients is lacking. This study aimed to determine the outcome of urgent suspicion of cancer referrals for head and neck cancer. METHODS AND METHODS All head and neck cancer urgent suspicion of cancer referrals in NHS Greater Glasgow and Clyde between June 2015 and May 2016 were analysed in regard to their clinical pathway. RESULTS There were 2116 urgent suspicion of cancer referrals in the one-year period. The overall cancer rate was 235 (11.8%), compared with 152 (7.6%) that resulted in a primary head and neck cancer diagnosis. Of the total, 851 (42.6%) were reassured and discharged after one clinic appointment; 536 (26.8%) were followed up for suspected benign pathology and 436 (21.8%) were actively investigated for cancer. CONCLUSION A significant proportion of patients attending urgent suspicion of cancer clinic appointments can be seen and discharged in one clinic appointment, provided there is same day imaging available. Cancer identification rates through urgent suspicion of cancer pathways remain low.

Abstract
Introduction The incidence of deep neck space infection (DNSI) is rising and appears to be related to falling rates of tonsillectomy. The purpose of this study was to assess demographics of patients presenting with DNSI and the financial burden to the National Health Service (NHS). Methods Data were collected retrospectively on patients aged over 16 years admitted to NHS Greater Glasgow and Clyde with DNSI between 2012 and 2016. Demographics, aetiology and use of hospital resources were reviewed. The cost of hospital admissions was calculated using data from NHS Scotland's Information Services Division, the local diagnostics division and the British National Formulary. Results Seventy-four patients were admitted with DNSI during the study period. Forty (54%) were male. The mean age was 44.0 years (range: 16-86 years). The most frequent source of infection was the tonsil (n=30, 40.5%). The most common infective organism was Streptococcus constellatus (n=9, 12.2%). The mean length of stay was 11 days. Fifty-five patients (74.3%) required operative intervention. The mean cost of admission per patient was £5,700 (range: £332-£46,700). Conclusions This study highlights the high cost burden of DNSI to the NHS. The incidence of DNSI in Glasgow has risen over the study period; contributing factors may include the reduced tonsillectomy rate and a reduction in antibiotic prescribing. As the incidence of DNSI continues to rise, there will be an increase in cost to the NHS, which must be planned for.

Abstract
OBJECTIVE To evaluate diagnostic performance of the emotional domain of the VoiSS questionnaire compared with the Hospital Anxiety and Depression Scale (HADS). DESIGN Cross-sectional questionnaire study. SETTING Tertiary referral centre voice clinic. PARTICIPANTS 210 consecutive voice clinic patients. MAIN OUTCOME MEASURES Screening with VoiSS and HADS questionnaires. Paired comparison, correlation, multinomial logistic regression and receiver-operating characteristic (ROC) curve analysis. RESULTS A total of 177 returned complete data sets. Ninety-six patients (54.2%) had functional dysphonia, and 81 (45.8%) had organic laryngeal disorders. Mean total VoiSS score = 39.7/120 (standard deviation (sd) 22.2). Mean emotional VoiSS subscale = 7.6/22 (sd 7.5). Mean HADS anxiety = 6.5/21 (sd 5.2) and depression mean = 7.1/21 (sd 4.8). There were 35 (20%) borderline anxiety and/or depression scores and 30 (17%) scores considered positive for 'caseness'. There was strong correlation between emotional VoiSS and HADS anxiety (Spearman's Rho = 0.68, P < 0.001) and HADS depression (Spearman's Rho = 0.62, P < 0.001). ROC curve analysis exhibited significant association between emotional VoiSS and HADS 'caseness' (area under curve = 0.88). In addition, functional dysphonia patients had lower mean VoiSS and HADS scores than patients with identifiable laryngeal abnormalities. CONCLUSION The VoiSS emotional subscale strongly correlates with HADS anxiety and depression scores and could be used as a measure of psychological distress. This could allow targeted psychological strategies, without additional psychometric questionnaires. Functional dysphonia has less association with psychological distress than certain organic laryngological disorders.

Abstract
WHAT IS KNOWN AND OBJECTIVE To date, there is no evidence to indicate the reliability of how patients self-report their own antibiotic usage in the community. Such data are fundamental in supporting antimicrobial stewardship practices, and so there is a need to determine its accuracy and reliability. COMMENT Patients in the community (n = 476) were required to recollect their antibiotic usage in the past three months. Simultaneously, similar information was obtained by careful extraction from their respective medical notes, which was qualitatively compared with the patient's recollection. Overall, concordance was high (88·1%), but age (<20 and >80 years) and sex (female) were significant factors of reliability. WHAT IS NEW AND CONCLUSION This study suggests that basic self-reporting of antibiotic usage amongst patients is relatively reliable, with increasing accuracy with years until 80 years. Where such information is critical, the current study can help decide who to interview and whose notes to interrogate, in the quest to obtain reliable and accurate information.

Abstract
Ocular ultrasound is now in increasing demand in routine ophthalmic clinical practice not only because it is noninvasive but also because of ever-advancing technology providing higher resolution imaging. It is however a difficult branch of ophthalmic investigations to grasp, as it requires a high skill level to interface with the technology and provide accurate interpretation of images for ophthalmic diagnosis and management. It is even more labor intensive to teach ocular ultrasound to another fellow clinician. One of the fundamental skills that proved difficult to learn and teach is the need for the examiner to “mentally convert” 2-dimensional B-scan images into 3-dimensional (3D) interpretations. An additional challenge is the requirement to carry out this task in real time. We have developed a novel approach to teach ocular ultrasound by using a novel 3D ocular model. A 3D virtual model is built using widely available, open source, software. The model is then used to generate movie clips simulating different movements and orientations of the scanner head. Using Blender, Quicktime motion clips are choreographed and collated into interactive quizzes and other pertinent pedagogical media. The process involves scripting motion vectors, rotation, and tracking of both the virtual stereo camera and the model. The resulting sequence is then rendered for twinned right- and left-eye views. Finally, the twinned views are synchronized and combined in a format compatible with the stereo projection apparatus. This new model will help the student with spatial awareness and allow for assimilation of this awareness into clinical practice. It will also help with grasping the nomenclature used in ocular ultrasound as well as helping with localization of lesions and obtaining the best possible images for echographic diagnosis, accurate measurements, and reporting.

Abstract
244 Background: Neoadjuvant cisplatin-based chemotherapy benefits patients with bladder cancer, particularly in the 30% with pathologic complete response (pCR) at cystectomy. Many patients with bladder cancer are not candidates for cisplatin. Taxane-based regimens have activity in urothelial cancer. ABI-007 is an albumin-bound paclitaxel with increased activity and decreased toxicity compared to standard paclitaxel preparations. Methods: Eligible pts have T2-4,N0,M0 or Tany,N1- 3,M0 bladder cancer with ECOG PS 0-1, and adequate marrow (granulocyte count > 1,500/mm3, platelet > 100,000/mm3, and hemoglobin > 9.0 g/dl), hepatic (transaminases < 2.5 X upper limit of normal, alkaline phosphatase < 2.5 X upper limit of normal, and bilirubin < 1.5 mg/dl) and renal function (serum creatinine < 2.0 mg/dl and/or creatinine clearance > 40 ml/min). Pts are treated with intravenous ABI-007 260 mg/m2 and carboplatin (target area under the curve=5) on day 1 with gemcitabine 800 mg/m2 on days 1 and 8, followed by radical cystectomy after three cycles of therapy. The primary study endpoint is the proportion of patients with pCR at cystectomy. Results: 27 patients have been enrolled. By clinical staging, 20 had T2 disease, 5 had T3, 2 had T4, and 2 had nodal enlargement. All are evaluable for toxicity with 22 evaluable for response (exclusions-3 for change in dose schedule, 1 each for refusal of cystectomy and withdrawal from study). 25/27 patients received all three cycles (78 total cycles) with doses reduced in 26 cycles for toxicity. All patients had transient grade 3-4 neutropenia and 17 received filgrastim, but only two had febrile neutropenia. Six pts had pCR with an additional 5 having residual carcinoma in situ (CIS) and 1 with T1 disease at cystectomy. 54% of evaluable patients had no muscle invasive disease at cystectomy. Conclusions: Neoajuvant ACG is active in bladder cancer with pCR rate nearing 30% and nearly as many patients with CIS but no residual invasive disease. Marrow toxicity is significant but manageable.

Abstract
Methods employed by the World Health Organization (WHO) are used during this study to determine the optimum storage conditions for maintaining the culturability of Streptococcus pneumoniae in skimmed milk, tryptone, glucose and glycerin (STGG) transport medium. A comparison of S. pneumoniae strains sensitive and resistant to penicillin showed no significant difference in their survival ability in STGG medium. Furthermore, it is confirmed that storage at -70 degrees C remains most effective for maintaining viability by culture of S. pneumoniae. Storage at -20 degrees C would only be acceptable in the short-term, while storage at +4 degrees C is not recommended. Of note, this study has shown STGG medium at room temperature to be an efficient growth medium for pneumococci in the short-term. This work will help to establish robust sampling protocols when performing community studies to ensure culturability of comparison between community and laboratory pneumococci survival.
