Abstract
PURPOSE Radical resections for abdominal wall tumors are rare, thus yielding limited data on reconstruction of defects. We describe surgical management and long-term outcomes following radical tumor resection. METHODS This was a single-center retrospective review of patients between January 2010 and December 2022. Variables included operative characteristics, wound complications, hernia development, tumor recurrence, and reoperation. A multivariable analysis compared wound morbidity for suture and mesh repairs while adjusting for defect width, fascial closure, and CDC wound class. RESULTS 120 patients were identified. Mean follow-up was 3.9 ± 3.4 years. Seventy-five (62.5%) of the masses were primary; most commonly desmoid (n = 25) and endometrioma (n = 27). Forty-five masses were metastases. Mean tumor width was 6.2 ± 3.4 cm; mean defect width was 8.1 ± 4.1 cm. Sixty-one patients (50.8%) had mesh placed, with variation in technique. Postoperative CT scans were available for 88 (73.3%) patients. Forty SSOs (33.3%), 11 SSIs (9.2%), and 18 (15%) SSOPIs occurred within 30 days. On multivariable analysis, increased defect width was associated with SSOPI (OR 1.17, p = 0.041) and CDC wound class II-III was associated with SSI (OR 8.38 and 49.1, p < 0.05) and SSOPI (OR 5.77 and 17.4, p < 0.05); mesh was not associated with these outcomes. Seven patients (5.8%) underwent 30-day reoperations and 35 (20.8%) required additional operations after 30 days. Thirteen percent developed abdominal wall (n = 8) or intra-abdominal tumor recurrence (n = 8) requiring reoperation. Twenty-seven (22.5%) patients developed hernias with a mean fascial defect width of 9.8 ± 7.2 cm. CONCLUSION Abdominal wall mass resections are morbid, often contaminated cases with high postoperative complication rates. Risks and benefits of mesh implantation should be tailored on an individual basis.

Abstract
PURPOSE The aim of this study was to determine whether a 9-week resistance training program based on high load (HL) versus low load combined with blood flow restriction (LL-BFR) induced a similar (i) distribution of muscle hypertrophy among hamstring heads (semimembranosus, SM; semitendinosus, ST; and biceps femoris long head, BF) and (ii) magnitude of tendon hypertrophy of ST, using a parallel randomized controlled trial. METHODS A total of 45 participants were randomly allocated to one of three groups: HL, LL-BFR, and control (CON). Both HL and LL-BFR performed a 9-week resistance training program composed of seated leg curl and stiff-leg deadlift exercises. Freehand 3D ultrasound was used to assess the changes in muscle and tendon volume. RESULTS The increase in ST volume was greater in HL (26.5 ± 25.5%) compared to CON (p = 0.004). No difference was found between CON and LL-BFR for the ST muscle volume (p = 0.627). The change in SM muscle volume was greater for LL-BFR (21.6 ± 27.8%) compared to CON (p = 0.025). No difference was found between HL and CON for the SM muscle volume (p = 0.178).There was no change in BF muscle volume in LL-BFR (14.0 ± 16.5%; p = 0.436) compared to CON group. No difference was found between HL and CON for the BF muscle volume (p = 1.0). Regarding ST tendon volume, we did not report an effect of training regimens (p = 0.411). CONCLUSION These results provide evidence that the HL program induced a selective hypertrophy of the ST while LL-BFR induced hypertrophy of SM. The magnitude of the selective hypertrophy observed within each group varied greatly between individuals. This finding suggests that it is very difficult to early determine the location of the hypertrophy among a muscle group.

Abstract
Background When experiencing mental distress, many university students seek support from their peers. In schools and mental health services, formalised peer support interventions have demonstrated some success but implementation challenges have been reported. This study aimed to assess the feasibility, acceptability and safety of a novel manualized peer support intervention and associated data collection processes. Methods A longitudinal mixed methods study was conducted following the pilot of a peer support intervention at a large London university between June 2021 and May 2022. The study utilised data routinely recorded on all students who booked a peer support session, focus groups with nine peer workers and five staff members implementing the intervention, pre-post intervention surveys with 13 students and qualitative interviews with 10 of those students. Results 169 bookings were made during the pilot, of which 130 (77%) were attended, with November the peak month. Staff and peer workers described strong motivation and commitment to implement the intervention, noting that the peer support model and peer worker role addressed previously unmet needs at the university. However, students described implementation problems relating to the coherence of the intervention and the burden of participation. While students mostly described acceptable experiences, there were examples where acceptability was lower. No adverse events were reported during the pilot. Conclusion The training and supervision of peer workers, and the provision of one-to-one peer support to students was found to be feasible, mostly acceptable, and safe. However, sustained implementation difficulties were observed. These pose challenges to the scalability of peer support in universities. We make recommendations to improve implementation of peer support including improving reach, greater clarity about the intervention, and fuller involvement of students throughout.

Abstract
The high density fluctuation poloidal wavenumber, kθ (kθ > 8 cm-1, kθρs > 5, ρs is the ion gyro radius using the ion sound velocity), measurement capability of a new Doppler backscattering (DBS) system at the DIII-D tokamak has been experimentally evaluated. In DBS, wavenumber (k) matching becomes more important at higher wavenumbers, owing to the exponential dependence of the measured signal loss factor on wave vector mismatch. Wave vector matching allows for the Bragg scattering condition to be satisfied, which minimizes the signal loss at higher k's. In the previous DBS system, without toroidal wave vector matching, the measured DBS signal-to-noise ratio at higher kθ (>8 cm-1) is substantially reduced, making it difficult to measure higher kθ turbulence. The new DBS system has been optimized to access higher wavenumber, kθ ≤ 20 cm-1, density turbulence measurement. The optimization hardware addresses fluctuation wave vector matching using toroidal steering of the launch mirror to produce a backscattered signal with improved intensity. The probe's sensitivity to high-k density fluctuations has been increased by approximately an order of magnitude compared to the old system that has been in use at DIII-D. Note that typical measurement locations are above or below the tokamak midplane on the low field side with normalized radial ranges of 0.5-1.0. The new DBS probe system with the toroidal matching of fluctuation wave vectors is thought to be critical to understanding high-k turbulent transport in fusion-relevant research at DIII-D.

Abstract
Abstract
Background
Glioblastoma is one of the most aggressive cancers, and hypoxia plays an essential role in its tumor- microenvironment. Tumor-associated microglia and macrophages (TAMs) have been reported to constitute up to 30 % of the cells, a fraction that is even higher in hypoxic areas. Single-cell mRNA sequencing of glioblastoma tumors has revealed vast heterogeneity, but the spatial aspects are not entirely defined yet. The aim of this study was to uncover differences between the hypoxic and normoxic tumor-microenvironment of human glioblastoma by high-end multiplexing with imaging mass cytometry.
Material and Methods
A tissue microarray (TMA) with normoxic and hypoxic areas from 4 IDH-wildtype glioblastomas was prepared based on the hypoxia marker hypoxia-inducing factor 1 alpha (HIF1 alpha). The TMA was stained with 18 metal-tagged antibodies covering TAMs, lymphocytes, immune checkpoints, vessels, tumor cells and proliferation. The Hyperion-CYTOF technology was used to ablate the samples and the images were analyzed by MCD viewer, Visiopharm software, and customized R scripts.
Results
Single-cell analysis of 160 fields covering around 45,000 cells in the glioblastoma microenvironment revealed multiple cellular phenotypes. It was revealed that proliferating TAMs (IBA1+, Ki67+) were more frequent in hypoxia, whereas proliferating vessels (CD34+, Ki67+) were more frequent in normoxia. Additionally, proliferating stem-like tumor cells (OLIG-2+, Ki67+) were more frequent in normoxia regions.
Conclusion
Our study revealed multiple cellular phenotypes in the glioblastoma microenvironment. The TAMs, endothelial and tumor cell phenotypes revealed may play a critical role in glioblastoma biology however this needs to be elucidated in future studies.

Abstract
BACKGROUND For patients with early American Joint Committee on Cancer (AJCC)-stage melanoma the combined loss of the autophagy regulatory protein AMBRA1 and the terminal differentiation marker loricrin in the peritumoral epidermis is associated with a significantly increased risk of metastasis. OBJECTIVES The aim of the present study was to evaluate the potential contribution of melanoma paracrine transforming growth factor (TGF)-β signalling to the loss of AMBRA1 in the epidermis overlying the primary tumour and disruption of epidermal integrity. METHODS Immunohistochemistry was used to analyse AMBRA1 and TGF-β2 in a cohort of 109 AJCC all-stage melanomas, and TGF-β2 and claudin-1 in a cohort of 30 or 42 AJCC stage I melanomas, respectively, with known AMBRA1 and loricrin (AMLo) expression. Evidence of pre-ulceration was analysed in a cohort of 42 melanomas, with TGF-β2 signalling evaluated in primary keratinocytes. RESULTS Increased tumoral TGF-β2 was significantly associated with loss of peritumoral AMBRA1 (P < 0·05), ulceration (P < 0·001), AMLo high-risk status (P < 0·05) and metastasis (P < 0·01). TGF-β2 treatment of keratinocytes resulted in downregulation of AMBRA1, loricrin and claudin-1, while knockdown of AMBRA1 was associated with decreased expression of claudin-1 and increased proliferation of keratinocytes (P < 0·05). Importantly, we show loss of AMBRA1 in the peritumoral epidermis was associated with decreased claudin-1 expression (P < 0·05), parakeratosis (P < 0·01) and cleft formation in the dermoepidermal junction (P < 0·05). CONCLUSIONS Collectively, these data suggest a paracrine mechanism whereby TGF-β2 causes loss of AMBRA1 overlying high-risk AJCC early-stage melanomas and reduced epidermal integrity, thereby facilitating erosion of the epidermis and tumour ulceration.

Abstract
Abstract
Aim
Fitness to practice (FtP) investigations by the General Medical Council (GMC) can be one of the most stressful experiences in a surgeon’s career. Demographic factors are known to alter the likelihood of GMC investigation. Despite this there are no studies assessing risk factors in surgeons for FtP sanctions. Thus, we used the newly created Intercollegiate Membership of Royal College of Surgeons (MRCS) examination database to identify risk factors for and the prevalence of GMC sanctions in early-career surgeons.
Method
FtP sanction data contained in the GMC list of registered medical practitioners (LRMP) database was linked at person-level to all UK graduates who had attempted MRCS Part A or Part B between September 2007 and January 2020. Data were anonymised by the Royal College of Surgeons of England prior to analysis.
Results
f 11,660 candidates who had attempted the MRCS within the study period only 31 (0.3%) candidates had GMC FtP sanctions within the last two years. Of these, 12 had active conditions on their registration, 7 had active undertakings and 14 had warnings. Candidate demographics were similar between cohorts and there were no significant differences between MRCS performance identified.
Conclusions
In this, the largest study of MRCS candidates to date, the prevalence of active FtP sanctions in early-career surgeons was 0.3%, significantly lower than the prevalence of sanctions across more experienced UK surgeons (0.9%). These data highlight early-career surgeons as a low-risk group for disciplinary action and should reassure patients and medical professionals of the rarity of FtP sanctions.

Abstract
Abstract
Introduction
Despite the practice of evidence-based medicine, superstitions remain common amongst healthcare workers around the world. Friday 13th is a day that can cause anxiety amongst many surgeons on-call. Our aim was to determine whether there is a significant difference between working an on-call as a surgeon on Friday 13th compared to the preceding Friday at a large teaching hospital.
Method
We conducted a retrospective, longitudinal cohort study that analysed admissions and operative data for all emergency general surgical and urology patients at a large teaching hospital over a five-year period. The main outcome measures assessed included the number of emergency surgical admissions, emergency general surgical operations and emergency urological operations.
Results
There was no statistically significant difference between the number of admissions (412 vs 405, p=0.835), number of general surgical operations (63 vs 49, p=0.069), and number of urological operations (2 vs 4, p=0.449) on Friday 13th compared to Friday 6th.
Conclusions
Friday 13th will inevitably be unlucky for some, but this study shows that being on-call on Friday 13th is just as unlucky as being on-call any other Friday.

Abstract
Abstract
Aim
The latest guidance in acute renal colic states that patients should have serum calcium and urate (stone bloods) measured during inpatient admission. The guidance also states that follow-up imaging should be in the form of computed tomography (CT)-, ultrasound (USS)-, or X-ray- kidney, ureters and bladder (KUB). X-ray intravenous urogram (IVU) is now considered obsolete as it can result in over-exposing patients to radiation. Aims of this 2-cycle QIP were twofold;
Method
Data was extracted from electronic patient records on whether or not they had stone bloods measured during admission and also what follow-up imaging was requested. In the first cycle baseline data was extracted. A stone proforma was then created, incorporating the latest guidelines. In the second cycle the impact of the stone proforma was assessed.
Results
The study included 119 patients. After introducing the stone proforma we were successful in improving the rate of stone bloods being measured, increasing from 13% to 53%. We were also successful in reducing the rate of performing X-ray IVU, decreasing from 25% to 14% of patients.
Conclusions
This QIP demonstrates that management of acute renal colic can be optimised using a stone proforma and move current practice towards best practice. This is supported by the ‘Getting it Right First Time’ (GIRFT) Urology report 2018. The third cycle is currently underway, and we hope to see further improved outcomes.

Abstract
Abstract
Aim
Successful completion of the MRCS examination is mandatory for progression into higher surgical (registrar) training in the UK. National selection for training programmes is a highly competitive process. Despite this, the ranking of applicants does not currently include MRCS performance scores. This offers a unique opportunity to compare two independent assessments of surgical trainees to establish whether MRCS performance can predict future surgical career outcomes and competitiveness in training.
Method
All UK candidates who attempted MRCS between 2007-2020 were matched to career outcome data using the GMC list of registered medical practitioners and anonymised (n = 2910). Chi-squared tests determined associations with first attempt MRCS pass/fail outcomes. Multinomial regression models were developed to establish the predictive power of success at MRCS in determining surgical specialty and training deanery choices.
Results
There was statistically significant variability in MRCS Part A pass rates, ranging from 55.1%-76.7% between surgical specialties (P=0.001) but no significant variability in Part B pass rates (P=0.655). There was significant variability in Part A and Part B pass rates between training deaneries (P=0.010 and P=0.036 respectively). Pass rates ranged from 59.9%-77.7% for Part A and 70.1%-85.0% for Part B between training deaneries. Those in more competitive specialties and training deaneries performed better in MRCS in terms of first attempt pass rate, scores and number of attempts taken to pass.
Conclusions
MRCS performance is an early predictor of surgical career choice and competitiveness. Trainees who perform well at MRCS are more likely to enter competitive surgical specialties and training deaneries.

Abstract
Abstract
Aim
The number of clinicians with disabilities is increasing, however there is no data on the performance of doctors with registered disabilities in the postgraduate environment. If we are to ensure diversity and equality within the workforce, we must first identify whether attainment differences exist in markers of performance. To address this, we assessed the impact of disabilities on performance in the MRCS.
Method
All UK medical graduates who had attempted MRCS Part A (n = 9,597) and Part B (n = 4,562) between 2007-2017 with linked disability data in the UK Medical Education Database (https://www.ukmed.ac.uk) were included. Univariate analysis identified associations with MRCS performance and logistic regression models identified independent predictors of success.
Results
Candidates with registered disabilities (n = 635) had lower MRCS Part A pass rates (46.3% vs 59.8% (p < 0.001)) but similar Part B pass rates (68.2% vs 70.9% (p = 0.339)). They were nearly twice as likely to fail Part A (odds ratio 0.55 [95% Confidence Interval 0.46-0.64]). When prior academic attainment (A-Levels and medical school performance) was accounted for, there was no statistically significant difference in the likelihood of MRCS success (p>0.05). Pass rates were similar for candidates with specific learning difficulties and those with other registered disabilities (p>0.05).
Conclusions
This is the first study to assess the impact of disability status and type on performance at a postgraduate medical examination. It appears that candidates with registered disabilities performed less well in formal, written examinations generally. Although our data indicate that current MRCS testing accommodations are fair, enabling performance unrestricted by disability.

Abstract
Measuring stream pollutant loads across the Great Barrier Reef (GBR) catchment area (GBRCA) is challenging due to the spatial extent, climate variability, changing land use and evolving land management practices, and cost. Thus, models are used to estimate baseline pollutant loads. The eWater Source modelling framework is coupled with agricultural paddock scale models and the GBR Dynamic SedNet plugin to simulate dissolved inorganic nitrogen (DIN) generation and transport processes across the GBRCA. Catchment scale monitoring of flow and loads are used to calibrate the models, and performance is assessed qualitatively and quantitatively. Modelling indicates almost half (47%) of the total modelled DIN load exported to the GBR lagoon is from the Wet Tropics, and almost half of the total modelled DIN load is from sugarcane areas. We demonstrate that using locally developed, customised models coupled with a complementary monitoring program can produce reliable estimates of pollutant loads.

Abstract
OBJECTIVE Despite rising numbers of doctors in the workforce with disabilities, little is known about the impact of disabilities on postgraduate performance. To ensure all groups are treated fairly in surgical training, it is essential to know whether any attainment differences exist in markers of surgical performance. To address this gap, we assessed the impact of disabilities on performance on the Intercollegiate Membership of the Royal College of Surgeons examination (MRCS). DESIGN Retrospective cohort study. SETTING Secondary care. PARTICIPANTS All UK MRCS candidates attempting Part A (n = 9600) and Part B (n = 4560) between 2007 and 2017 with linked disability data in the UK Medical Education Database (https://www.ukmed.ac.uk) were included. MAIN OUTCOME MEASURES Chi-square tests and correlation coefficients established univariate associations with MRCS performance, while multiple logistic regressions identified independent predictors of success. RESULTS Though MRCS Part B pass rates were similar (p = 0.339), candidates with registered disabilities had significantly lower first-attempt Part A pass rates (46.3% vs. 59.8%, p < 0.001). Candidates with disabilities also performed less well in examinations taken throughout school and medical school, and after adjusting for prior academic performance and sociodemographic predictors of success, logistic regression found that candidates with disabilities were no less likely to pass MRCS than their peers (odds ratio 1.04, 95% confidence interval 0.66 to 1.62). No significant variation was found in MRCS performance between type of disability or degree of limitations caused by disability (p > 0.05). CONCLUSION Although candidates with registered disabilities performed less well in formal, written examinations, our data indicate that they are as likely to pass MRCS at first attempt as their peers who achieved similar grades at high school and medical school. In order to enable equity in career progression, further work is needed to investigate the causes of attainment differences in early career assessments.

Abstract
BACKGROUND Fitness to practice (FtP) investigations by the General Medical Council (GMC) safeguard patients and maintain the integrity of the medical profession. The likelihood of FtP sanctions is influenced by specialty and socio-demographic factors and can be predicted by performance at postgraduate examinations. This is the first study to characterise the prevalence of FtP sanctions in early-career surgeons and to examine the association with performance at the Membership of the Royal College of Surgeons (MRCS) examination. METHODS All UK graduates who attempted MRCS between September 2007-January 2020 were matched to the GMC list of registered medical practitioners. Clinicians who had active FtP sanctions between 28th August 2018 and 28th August 2020 were identified. Data were anonymised by RCS England prior to analysis. RESULTS Of 11,660 candidates who attempted MRCS within the study period, only 31 (0.3%) had FtP sanctions between 2018 and 2020. Of these, 12 had active conditions on registration, seven had undertakings and 14 had warnings. There was no statistically significant difference in MRCS performance in either Parts A or B of the examination for those with and those free from FtP sanctions (P > 0.05). CONCLUSIONS In this, the largest study of MRCS candidates to date, the prevalence of active FtP sanctions in early-career surgeons was 0.3%, significantly lower than the prevalence of sanctions across more experienced UK surgeons (0.9%). These data highlight early-career surgeons as a low-risk group for disciplinary action and should reassure patients and medical professionals of the rarity of FtP sanctions.

Abstract
Introduction Training in Urology is often limited at an undergraduate level, especially in the wake of the COVID-19 pandemic. It is not uncommon that a trainee’s first experience of Urology is when they encounter urological patients as a clinician and studies have revealed that graduates are lacking knowledge and confidence in managing urological pathology. Many trainees across the world are unable to access vital learning resources to address this gap in knowledge due to exorbitant prices set by publishing companies. Method To address the need for affordable standardised education, ‘Urology for Medical Students and Junior Doctors’ was created. This self-published eBook was written and peer-reviewed by urologists to create a relevant learning resource that is affordable for all. Results Over 1000 copies of the eBook were downloaded in the first 90 days after publication by trainees across the world. It has been downloaded internationally by a diverse range of allied healthcare professionals. All profits generated from sales are donated to charities investing in medical education. Conclusions This eBook stands as an example of how we as educationalists and clinicians can produce affordable learning resources for trainees worldwide; standardising training, improving patient safety and reducing barriers to learning.

Abstract
Abstract
Background
Selection into UK medical school typically involves a combination of three measures: prior academic attainment, selection tests (e.g., the University Clinical Aptitude Test (UCAT), Biomedical Admissions Test (BMAT), Graduate Medical School Admissions Test (GAMSAT)), and an interview. We investigated whether prior attainment and selection test scores can predict MRCS success.
Method
We used the UKMED database to analyse selection data for all UK graduates who attempted MRCS Part A (n = 9729) and Part B (n = 4644) between 2007-2017. Univariate analysis and Pearson correlation coefficients were used to examine the relationship between selection scores and first attempt MRCS success.
Results
Successful MRCS Part A candidates had better A-Levels and higher scores in UCAT, BMAT and GAMSAT examinations (p < 0.001) than their unsuccessful peers. No statistically significant difference was observed for MRCS Part B. A moderate positive correlation was found between Part A, BMAT (r = 0.315, p < 0.001) and GAMSAT scores (r = 0.346, p < 0.001). A weak positive correlation was found between Part A, A-Level (r = 0.144, p < 0.001) and UCAT scores (r = 0.246, p < 0.001).
Conclusions
A-level results and medical school selection tests predict success in the knowledge-based (Part A) MRCS examination.

Abstract
Abstract
Background
Identifying factors that predict success in the Membership of the Royal College of Surgeons (MRCS) examination can aid trainees’ exam preparation and help deaneries identify candidates likely to require additional support. We assessed whether performance at Medical School and UK Foundation Programme selection (Educational Performance Measurement (EPM) and Situational Judgement Test (SJT)) predicted MRCS success.
Method
We analysed data from the UKMED Database for UK graduates who had attempted MRCS Part A (n = 1,975) and Part B (n = 630) between 2013-2017. Univariate analysis examined the relationship between performance and the likelihood of passing MRCS at first attempt. Logistic regression identified independent predictors of MRCS success.
Results
Each additional EPM decile increased the chances of passing MRCS by 52% for Part A (odds ratio 1.52 [95% confidence interval 1.46-1.60]) and 27% for Part B (1.27 [1.18-1.38]). Each EPM point awarded for degrees increased the likelihood of passing Part A by 29% (1.29 [1.12-1.48]). SJT score was not a statistically significant independent predictor of MRCS success (P>0.05).
Conclusions
This is the first study to investigate the relationship between UK medical school performance and postgraduate surgical exam success. Higher ranked students are more likely to succeed in the MRCS compared to their lower ranked peers.

Abstract
Abstract
Background
UK medical schools vary in terms of factors such as mission, specific curricula and pedagogy. As relatively little is understood about the impact of these differences at a post-graduate level, we examined the relationship between medical school and MRCS success.
Method
Using the UKMED database we analysed data on UK medical graduates who attempted MRCS Part A (n = 9729) and MRCS Part B (n = 4644) between 2007-2017. Univariate analysis characterised the relationship between medical school and first attempt MRCS success. Logistic regression modelling identified independent predictors of MRCS success.
Results
MRCS pass rates differed significantly between medical schools (P < 0.001). Trainees from standard-entry 5-year programmes were more likely to pass MRCS at first attempt compared to those from extended (Gateway) courses ((Part A (Odds Ratio (OR) 3.72 [95% Confidence Interval (CI) 2.69-5.15]); Part B (OR 1.67 [1.02-2.76])). Non-graduates were more likely to pass Part A (OR 1.40 [1.19-1.64]) and Part B (OR 1.66 [1.24-2.24]). Russell Group graduates were more likely to pass MRCS Part A (OR 1.79 [1.56-2.05]) and Part B (OR 1.24 [1.03-1.49])).
Conclusions
Medical programme and medical school are associated with MRCS success. Further research is needed to tease out the relationship between individual factors, medical school and MRCS performance.

Abstract
The eWater Source modelling framework has been modified to support the Great Barrier Reef (GBR) Dynamic SedNet catchment modelling concept, which is used to simulate fine sediment and particulate nutrient generation, loss, and transport processes across GBR catchments. Catchment scale monitored data sets are used to calibrate and evaluate models. Model performance is assessed qualitatively and quantitatively. Modelling predicts that approximately half of generated sediment is delivered to the GBR lagoon; the remainder is deposited on floodplains, trapped in reservoirs or lost through other minor processes (e.g. irrigation extractions). Gullies are the major source of sediment, with comparable contributions from hillslopes and streambanks. Hillslope sources are considered the major source of particulate nutrients across the GBR catchments. We demonstrate that using locally developed, customised models coupled with a complementary monitoring program can produce credible modelled estimates of pollutant loads and provide a platform for testing catchment scale assumptions and scenarios.

Abstract
BACKGROUND Limited evidence exists which details changes in quality of life, shoulder activity level, kinesiophobia, shoulder pain and disability following a first-time traumatic anterior shoulder dislocation (FTASD) in people treated non-operatively. This study had three objectives: (1) to examine quality of life, pain, disability and kinesiophobia after an FTASD within 12 weeks, (2) to examine whether these variables were different in people with and without recurrent shoulder instability and (3) to assess how these variables changed over 12 months. METHODS A prospective cohort study was undertaken in people with an FTASD aged between 16 and 40 years. Measures of quality of life, kinesiophobia, shoulder activity, shoulder pain and disability were recorded within 12 weeks of an FTASD and at 3, 6, 9 and 12 months. RESULTS An FTASD negatively impacted quality of life, shoulder pain and function and these variables improved over time. People with recurrent shoulder instability had poorer quality of life 12 months after an FTASD. Across the entire cohort, kinesiophobia did not significantly change across time in people following an FTASD. CONCLUSIONS Quality of life was significantly affected by an FTASD in people with recurrent shoulder instability. Across the entire cohort of people with an FTASD, kinesiophobia remained elevated in people following an FTASD. LEVEL OF EVIDENCE Level 1 prognostic study.

Abstract
The COVID-19 pandemic resulted in an unprecedented reduction in the delivery of surgical services worldwide, especially in non-urgent, non-cancer procedures. A prolonged period without operating (or ‘layoff period’) can result in surgeons experiencing skill fade (both technical and non-technical) and a loss of confidence. While senior surgeons in the UK may be General Medical Council (GMC) validated and capable of performing a procedure, a loss of ‘currency’ may increase the risk of error and intraoperative patient harm, particularly if unexpected or adverse events are encountered. Dual surgeon operating may mitigate risks to patient safety as surgeons regain currency while returning to non-urgent operating and may also be beneficial after the greatly reduced activity observed during the COVID-19 pandemic for low-volume complex operations. In addition, it could be a useful tool for annual appraisal, sharing updated surgical techniques and helping team cohesion. This paper explores lessons from aviation, a leading industry in human factors principles, for regaining surgical skills currency. We discuss real and perceived barriers to dual surgeon operating including finance, training, substantial patient waiting lists, and intraoperative power dynamics.

Abstract
The COVID-19 pandemic has catalysed the computerisation and online delivery of postgraduate examinations. Social distancing regulations and lockdown measures resulted in many written and clinical examinations being cancelled during the initial surge of the virus. In an effort to reinstate the assessment of trainees and enable career progression, the UK medical regulator, the General Medical Council (GMC) has approved unprecedented changes to clinical examinations, including virtual assessment. We outline the changes made and the advantages and disadvantages of these new examination formats. We discuss ways for candidates and examiners to optimise their virtual environment and develop skills that can improve performance.

Abstract
The COVID-19 pandemic has changed training and recruitment in urology in unprecedented ways. As efforts are made to ensure trainees can continue to progress, lessons can be learned to improve training and urological practice even after the acute phase of the pandemic is over. Novel methods of education through virtual learning have burgeoned amidst the social distancing the pandemic has brought. The importance of training in human factors and non-technical skills has also been brought to the fore while operating under the constraints of personal protective equipment and working in new teams and unfamiliar environments. This paper critically appraises the available evidence of how urological training has been affected by COVID-19 and the lessons we have learned and continue to learn going forward. Level of Evidence Not Applicable.

Abstract
BACKGROUND Evidence for the effectiveness of vitiligo treatments is limited. OBJECTIVES To determine the effectiveness of (i) handheld narrowband UVB (NB-UVB) and (ii) a combination of potent topical corticosteroid (TCS) and NB-UVB, compared with TCS alone, for localized vitiligo. METHODS A pragmatic, three-arm, placebo-controlled randomized controlled trial (9-month treatment, 12-month follow-up). Adults and children, recruited from secondary care and the community, aged ≥ 5 years and with active vitiligo affecting < 10% of skin, were randomized 1 : 1 : 1 to receive TCS (mometasone furoate 0·1% ointment + dummy NB-UVB), NB-UVB (NB-UVB + placebo TCS) or a combination (TCS + NB-UVB). TCS was applied once daily on alternating weeks; NB-UVB was administered on alternate days in escalating doses, adjusted for erythema. The primary outcome was treatment success at 9 months at a target patch assessed using the participant-reported Vitiligo Noticeability Scale, with multiple imputation for missing data. The trial was registered with number ISRCTN17160087 on 8 January 2015. RESULTS In total 517 participants were randomized to TCS (n = 173), NB-UVB (n = 169) and combination (n = 175). Primary outcome data were available for 370 (72%) participants. The proportions with target patch treatment success were 17% (TCS), 22% (NB-UVB) and 27% (combination). Combination treatment was superior to TCS: adjusted between-group difference 10·9% (95% confidence interval 1·0%-20·9%; P = 0·032; number needed to treat = 10). NB-UVB alone was not superior to TCS: adjusted between-group difference 5·2% (95% CI - 4·4% to 14·9%; P = 0·29; number needed to treat = 19). Participants using interventions with ≥ 75% expected adherence were more likely to achieve treatment success, but the effects were lost once treatment stopped. Localized grade 3 or 4 erythema was reported in 62 (12%) participants (including three with dummy light). Skin thinning was reported in 13 (2·5%) participants (including one with placebo ointment). CONCLUSIONS Combination treatment with home-based handheld NB-UVB plus TCS is likely to be superior to TCS alone for treatment of localized vitiligo. Combination treatment was relatively safe and well tolerated but was successful in only around one-quarter of participants.

Abstract
The COVID-19 pandemic has brought unprecedented changes in healthcare and surgical training, with elective operating reduced or stopped, conferences rearranged and examinations cancelled. Trainees and trainers have adapted, creating innovative and resourceful ways to continue learning, enabling progression through surgical training. With rising COVID-19 cases across the world and further waves of infections likely, we reflect on recent changes to surgical training and discuss how best to support the next generation of surgeons during this period of uncertainty.

Abstract
BACKGROUND Economic evidence for vitiligo treatments is absent. OBJECTIVES To determine the cost-effectiveness of (i) handheld narrowband ultraviolet B (NB-UVB) and (ii) a combination of topical corticosteroid (TCS) and NB-UVB compared with TCS alone for localized vitiligo. METHODS Cost-effectiveness analysis alongside a pragmatic, three-arm, placebo-controlled randomized controlled trial with 9 months' treatment. In total 517 adults and children (aged ≥ 5 years) with active vitiligo affecting < 10% of skin were recruited from secondary care and the community and were randomized 1: 1: 1 to receive TCS, NB-UVB or both. Cost per successful treatment (measured on the Vitiligo Noticeability Scale) was estimated. Secondary cost-utility analyses measured quality-adjusted life-years using the EuroQol 5 Dimensions 5 Levels for those aged ≥ 11 years and the Child Health Utility 9D for those aged 5 to < 18 years. The trial was registered with number ISRCTN17160087 on 8 January 2015. RESULTS The mean ± SD cost per participant was £775 ± 83·7 for NB-UVB, £813 ± 111.4 for combination treatment and £600 ± 96·2 for TCS. In analyses adjusted for age and target patch location, the incremental difference in cost for combination treatment compared with TCS was £211 (95% confidence interval 188-235), corresponding to a risk difference of 10·9% (number needed to treat = 9). The incremental cost was £1932 per successful treatment. The incremental difference in cost for NB-UVB compared with TCS was £173 (95% confidence interval 151-196), with a risk difference of 5·2% (number needed to treat = 19). The incremental cost was £3336 per successful treatment. CONCLUSIONS Combination treatment, compared with TCS alone, has a lower incremental cost per additional successful treatment than NB-UVB only. Combination treatment would be considered cost-effective if decision makers are willing to pay £1932 per additional treatment success.

Abstract
The recent coronavirus disease 2019 outbreak was met by major reconfiguration of Urology health care services with cancellation of elective surgery and deployment of non face to face models for providing outpatient care. Urologists were faced with challenging decisions to stratify their patients into risk groups for assigning the appropriate, safe method of care delivery. Guidelines were swiftly produced by Urological societies to enhance this process but there has been limited uniformity and multiple publications from several institutions. We have conducted this critical review to appraise the current recommendations for providing Urology care during the coronavirus disease 2019 pandemic. The secondary outcome was identifying novel models for care delivery. Results were presented in tables categorising the recommendation by disease and its risk stratification. Results were presented according to the aspect of care: triage for surgery, operative, post-operative and outpatient care. This review reported differing recommendations from Urological societies on the prioritisation of services with limited consideration for individual patient-related factors. Telemedicine has been utilised well during the pandemic to maintain patient pathways. The role of telemedicine in future Urological practice looks promising and more development is required. Level of evidence: Not applicable.

Abstract
Upgrades to electronic hardware and detector design have been made to the JET thin-foil Faraday cup fast ion loss detector [Darrow et al., Rev. Sci. Instrum. 75, 3566 (2004)] in anticipation of the upcoming deuterium-tritium (DT) campaign. An improved foil stack design has been implemented, which greatly reduces the number of foil-to-foil shorts, and triaxial cabling has mitigated ambient noise pickup. Initial tests of 200 kHz digitizers, as opposed to the original 5 kHz digitizers, have provided enhanced analysis techniques and direct coherence measurements of fast ion losses with magnetohydrodynamic activity. We present recent loss measurements in JET deuterium plasmas correlated with kink modes, fishbone modes, edge-localized modes, and sawteeth. Sources of systematic noise are discussed with emphasis on capacitive plasma pickup. Overall, the system upgrades have established a diagnostic capable of recording alpha particle losses due to a wide variety of resonant fast ion transport mechanisms to be used in future DT-experiments and modeling efforts.

Abstract
BACKGROUND Chronic urticaria (CU) is a skin condition characterized by repeated occurrence of itchy weals and/or angio-oedema for > 6 weeks. AIM To provide data demonstrating the real-life burden of CU in the UK. METHODS This UK subset of the worldwide, prospective, noninterventional AWARE study included patients aged 18-75 years diagnosed with H1-antihistamine (H1-AH)-refractory chronic spontaneous urticaria (CSU) for > 2 months. Baseline characteristics, disease activity, treatments, comorbidities and healthcare resource use were documented. Quality of life (QoL), work productivity and activity impairment were assessed. RESULTS Baseline analysis included 252 UK patients. Mean age and body mass index were 45.0 years and 29.0 kg/m2 , respectively. Most patients were female (77.8%) and had moderate/severe disease activity (mean Urticaria Activity Score over 7 days was 18.4) and a 'spontaneous' component to their CU (73.4% CSU; 24.6% CSU and chronic inducible urticaria). Common comorbidities included depression/anxiety (24.6%), asthma (23.8%) and allergic rhinitis (12.7%). A previous treatment was recorded for 57.9% of patients. Mean Dermatology Life Quality Index score was 9.5, and patients reported impairments in work productivity and activity. Healthcare resource use was high. Severity of CSU was associated with female sex, obesity, anxiety and diagnosis. Only 28.5% of patients completed all nine study visits, limiting analysis of long-term treatment patterns and disease impact. CONCLUSIONS Adult H1-AH-refractory patients with CU in the UK reported high rates of healthcare resource use and impairment in QoL, work productivity and activity at baseline. The differing structures of UK healthcare may explain the high study discontinuation rates versus other countries.

Abstract
BACKGROUND Nab-paclitaxel plus gemcitabine (nabP+gemcitabine) offers modest survival gains for patients with metastatic pancreatic ductal adenocarcinoma (PDAC). Sequential scheduling of nabP+gemcitabine in a PDAC mouse model improved efficacy; this hypothesis was tested in a clinical trial. METHODS Patients with previously untreated metastatic PDAC were randomised to receive nabP+gemcitabine administered either concomitantly on the same day, or sequentially, with gemcitabine administered 24 h after nabP. The primary outcome measure was progression-free survival (PFS). Secondary outcome measures were objective response rate (ORR), overall survival (OS), safety, quality of life (QoL) and predictive biomarkers. RESULTS In total, 71 patients received sequential (SEQ) and 75 concomitant (CON) treatment. Six-month PFS was 46% with SEQ and 32% with CON scheduling. Median PFS (5.6 versus 4.0 months, hazard ratio [HR] 0.67, 95% confidence interval [95% CI] 0.47-0.95, p = 0.022) and ORR (52% versus 31%, p = 0.023) favoured the SEQ arm; median OS was 10.2 versus 8.2 months (HR 0.93, 95% CI 0.65-1.33, p = 0.70). CTCAE Grade ≥3 neutropaenia incidence doubled with SEQ therapy but was not detrimental to QoL. Strongly positive tumour epithelial cytidine deaminase (CDA) expression favoured benefit from SEQ therapy (PFS HR 0.31, 95% CI 0.13-0.70). CONCLUSIONS SEQ delivery of nabP+gemcitabine improved PFS and ORR, with manageable toxicity, but did not significantly improve OS.

Abstract
Our professional and private lives changed on March 11 2020 when the coronavirus disease 2019 (COVID-19) was declared a pandemic by the WHO. By March 16, surgical training was suspended, MRCS and FRCS examinations cancelled and all courses postponed. In theory, essential cancer surgery, emergency and trauma operating will continue. All elective, non-essential cases are currently cancelled. While we adapt to our new ways of working, we remind ourselves that surgeons are flexible, resilient and, ultimately, we are doctors in the first instance. We present a short article on operating during the COVID-19 pandemic.

Abstract
Abstract
Phytate, a naturally occurring organic compound found in plant seeds, roots, and tubers, was determined in a collaborative study using a modified anion-exchange method. Seven samples (peanut flour, oats, rice, isolated soybean protein, a vegetarian diet composite, wheat bran, and whole wheat bread), supplied as blind duplicate samples, were analyzed in triplicate by 7 collaborators. Phytate concentrations in the samples ranged from 2.38 to 46.70 mg/g. Relative standard deviations (RSD = CV) for repeatability ranged from 2.5 to 10.1%, and for reproducibility, from 4.5 to 11.0%. The method has been adopted official first action.

Abstract
Abstract
HIV disproportionately affects Black and Latino people in the United States, but data on longitudinal neurocognitive patterns for these groups are scarce. This study evaluated the incidence and predictors of neurocognitive decline by ethnicity/race in a cohort of Black, Latino, and White people living with HIV (PLWH). Participants included 499 PLWH (43.5% White, 42.7% Black, 13.8% Latino; mean age at baseline = 43.5) from the six-site CNS HIV Anti-Retroviral Therapy Effects Research (CHARTER) study. Participants completed comprehensive neurocognitive and neuromedical evaluations over 3-7 study visits for an average of 2.8 years (SD = 1.1). Interpertation of neurocognitive change was based on published methods using regression-based norms that correct for baseline performance and practice effects. Survival analyses investigated the relationship between ethnicity/race and neurocognitive change, and predictors of neurocognitive decline. In follow-up, 108 participants (21.6%) declined, 311 (62.3%) remained stable, and 80 (16.0%) improved. In Cox proportional hazard models, hazard ratios for neurocognitive decline were increased for Latinos compared to Whites (HR = 2.19, 95%CI = 1.32-3.63, p = .002) and Blacks (HR = 1.87, 95%CI = 1.14-3.04, p = .01). Including significant covariates (baseline nadir CD4, hepatitis C Virus, and VACS Index: a composite marker of physical health among PLWH)did not significantly decrease the elevated risk for decline among Latinos. We found that Latino PLWH appear to have higher risk of neurocognitive decline compared to White and Black PLWH. Traditional markers of HIV disease and physical health at baseline did not explain this elevated risk of neurocognitive decline. Future research examining economic, socio-environmental, and culturally-relevant biomedical factors may help to explain this observed ethnic/racial disparity in longitudinal neurocognitive function in HIV.

Abstract
BACKGROUND The updated American Joint Committee on Cancer (AJCC) staging criteria for melanoma remain unable to identify high-risk stage I tumour subsets. OBJECTIVES To determine the utility of epidermal autophagy and beclin 1 regulator 1 (AMBRA1)/loricrin (AMLo) expression as a prognostic biomarker for AJCC stage I cutaneous melanoma. METHODS Peritumoral AMBRA1 expression was evaluated in a retrospective discovery cohort of 76 AJCC stage I melanomas. AMLo expression was correlated with clinical outcomes up to 12 years in two independent powered, retrospective validation and qualification cohorts comprising 379 AJCC stage I melanomas. RESULTS Decreased AMBRA1 expression in the epidermis overlying primary melanomas in a discovery cohort of 76 AJCC stage I tumours was associated with a 7-year disease-free survival (DFS) rate of 81·5% vs. 100% survival with maintained AMBRA1 (P < 0·081). Following an immunohistochemistry protocol for semi-quantitative analysis of AMLo, analysis was undertaken in validation (n = 218) and qualification cohorts (n = 161) of AJCC stage I melanomas. Combined cohort analysis revealed a DFS rate of 98·3% in the AMLo low-risk group (n = 239) vs. 85·4% in the AMLo high-risk cohort (n = 140; P < 0·001). Subcohort multivariate analysis revealed that an AMLo hazard ratio (HR) of 4·04 [95% confidence interval (CI) 1·69-9·66; P = 0·002] is a stronger predictor of DFS than Breslow depth (HR 2·97, 95% CI 0·93-9·56; P = 0·068) in stage IB patients. CONCLUSIONS Loss of AMLo expression in the epidermis overlying primary AJCC stage I melanomas identifies high-risk tumour subsets independently of Breslow depth. What's already known about this topic? There is an unmet clinical need for biomarkers of early-stage melanoma. Autophagy and beclin 1 regulator 1 (AMBRA1) is a proautophagy regulatory protein with known roles in cell proliferation and differentiation, and is a known tumour suppressor. Loricrin is a marker of epidermal terminal differentiation. What does this study add? AMBRA1 has a functional role in keratinocyte/epidermal proliferation and differentiation. The combined decrease/loss of peritumoral AMBRA1 and loricrin is associated with a significantly increased risk of metastatic spread in American Joint Committee on Cancer (AJCC) stage I tumours vs. melanomas, in which peritumoral AMBRA1 and loricrin are maintained, independently of Breslow depth. What is the translational message? The integration of peritumoral epidermal AMBRA1/loricrin biomarker expression into melanoma care guidelines will facilitate more accurate, personalized risk stratification for patients with AJCC stage I melanomas, thereby facilitating stratification for appropriate follow-up and informing postdiagnostic investigations, including sentinel lymph node biopsy, ultimately resulting in improved disease outcomes and rationalization of healthcare costs.

Abstract
Background Glycolysis is altered in various kidney diseases, but little is known about glycolysis in pre-eclampsia, a multi-system disorder with major pathological effects on the kidney. Urinary exosomes provide a non-invasive alternative for studying changes in kidney metabolism. This study aims to characterise the expression and phosphorylation of isozymes of the key glycolytic regulatory protein, 6-phosphofructokinase-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2), in urinary exosomes of subjects with pre-eclampsia (PE), compared to normotensive non-pregnant (NC) and normotensive pregnant (NP) controls. Methods A cross-sectional study of NC (n = 19), NP (n = 23) and PE (n = 29) subjects was performed. Exosomes were isolated from urine samples by differential ultracentrifugation, and then analyzed by Western blot and densitometry for expression of PFK-2/FBPase-2 isozymes (PFKFB2, PFKFB3 and PFKFB4) and phosphorylation of PFKFB2 at residues Ser483 and Ser466 and PFKFB3 at Ser461. Results PFKFB2 expression was increased 4.7-fold in PE compared to NP (p < 0.001). PFKFB2 phosphorylation at Ser483 was increased 2.6-fold in PE compared to NP (p = 0.002). Expression of phosphorylated PFKFB2/PFKFB3 at Ser466/Ser461 was increased in PE, being present in 77.4% (95% CI 59.9–88.9%) of PE and 8.3% (95% CI 1.2–27.0%) of NP samples (p < 0.001). PFKFB3 was more commonly expressed in PE, detected in 90.3% (95% CI 74.3–97.4%) of PE and 8.3% (95% CI 1.2–27.0%) of NP samples (p < 0.001). PFKFB4 had a 7.2-fold increase in expression in PE compared to NP (p < 0.001). No significant differences between NP and NC groups were observed. Conclusion Regulatory proteins that increase glycolysis are increased in the urinary exosomes of subjects with pre-eclampsia, suggesting that renal glycolysis may be increased in this condition.

Abstract
Abstract
Background
High mammographic breast density is the primary reason for missed cancers or delayed detection on mammography, and is associated with a higher rate of advanced and interval cancers which increase breast cancer mortality. Digital breast tomosynthesis (DBT) has been shown to reduce false positive findings relative to 2D mammography but does not eliminate the potential for tumor masking in dense breasts due to the similar x-ray attenuation characteristics of tumors and normal fibroglandular tissue. Molecular Breast Imaging (MBI) performed with a dedicated gamma camera to detect functional uptake of a radiotracer, Tc-99m sestamibi, has been shown to reveal breast cancers obscured by density on mammography. In single-institution studies, adding MBI to 2D mammography in women with dense breasts detected an additional 5 to10 invasive cancers per 1000 screened, with modest increases in recall rate (6 to 8%) at a lower cost-per-cancer detected than mammography alone. Despite this promising evidence, the lack of multicenter trial data has limited wider acceptance. Also, MBI has yet to be compared to DBT, which in some centers has replaced 2D mammography screening. We present interim results from a multicenter trial comparing cancer detection rate of DBT and MBI in screening of women with mammographically dense breasts.
Methods
In this ongoing, prospective, multicenter clinical trial, asymptomatic women aged 40-75 years with dense breasts on prior mammogram and no prior history of supplemental screening are invited to undergo two annual rounds of concurrent DBT and MBI. MBI is performed with injection of 300 MBq Tc-99m sestamibi with a dual-head semiconductor-based gamma camera. Screening tests are interpreted independently. Here, preliminary cancer detection rates (cancers per 1000 women screened), recall rates, and biopsy rates of DBT and MBI for initial screening are reported.
Results
In 537 women out of a planned 3000 who have completed the first round of screening, 7 cancers were detected: one by DBT only and 6 by MBI only, giving cancer detection rates of 1.9 for DBT vs. 11.2 for MBI and incremental cancer detection rate of 9.3 for MBI. The one DBT-only cancer was a node-negative 0.8 cm invasive lobular carcinoma. All 6 cancers detected by MBI were invasive; 5 of 6 were node negative (median size 1.0 cm; range 0.6 to 2.6 cm). Recall rate was 11% (60/537) for DBT alone; 16% (84/537) for MBI alone, and 21% (115/537) for the combination. Biopsy was prompted by DBT in 13 patients (PPV 8% [1/13]); by MBI in 23 patients (PPV 26% [6/23]); and by the combination of modalities in 33 (PPV 21% [7/33]).
Conclusion
These preliminary results demonstrate that MBI detects invasive breast cancers occult on DBT in dense breasts. Data from a second screening round will allow calculation of sensitivity and specificity, and determination of the impact of screening MBI in reducing advanced (> 2 cm) and interval cancers. Additional planned analyses will evaluate a denoising algorithm for further reduction in MBI radiation dose to match that of DBT.

Abstract
This review presents the first detailed presentation of the parallelism between the Tuskegee Syphilis Study and the Captain America graphic novel 'TRUTH: Red, White and Black', published as a graphic novel by Marvel Comics in 2004 as a paperback, and then in 2009 as a hardcover. First written, published and distributed monthly in 2003 as pre-sequel seven comic book series to tell the story of the origins of the WWII superhero Captain America. In 2003, Marvel Comics chose to tell a 'very dark story' to explain the origins of Captain America, a half century after the initial introduction of Captain America as a WWII action hero in 1940. By detailing-for the first time-nine parallel aspects between these two storylines, this review demonstrates how Marvel Comics brought the tragic Tuskegee Syphilis Study story into the popular press, thus reaching an audience far beyond traditional bioethics academicians. This review is intended to stimulate and guide classroom discussions on the ethical issues at the core of the infamous Tuskegee Syphilis Study allowing bioethical issues to be made more accessible to the general public, via school curriculums, by the use of graphic novels.

Abstract
Simulations and laboratory tests are used to design and optimize a quasi-optical system for cross-polarization scattering (CPS) measurements of magnetic turbulence on the DIII-D tokamak. The CPS technique uses a process where magnetic turbulence scatters electromagnetic radiation into the perpendicular polarization enabling a local measurement of the perturbing magnetic fluctuations. This is a challenging measurement that addresses the contribution of magnetic turbulence to anomalous thermal transport in fusion research relevant plasmas. The goal of the new quasi-optical design is to demonstrate the full spatial and wavenumber capabilities of the CPS diagnostic. The approach used consists of independently controlled and in vacuo aiming systems for the probe and scattered beams (55-75 GHz).
