Abstract
Introduction
Complex health issues, co-morbidities and the number of patients living with frailty are critical concerns associated with the ageing population (Kojima et al, 2019). In this wider context, there is an emphasis on targeting resources efficaciously within the NHS. A consequence of capacity constraints, inpatient physiotherapy teams across the OPU at a large urban teaching hospital, prioritise their patient caseload, but lack evidence-based guidance on dosage and frequency of physiotherapy intervention, to inform the process. The aim of the quality improvement project was to design and deliver a staff education and training package to facilitate implementation of a newly-developed, evidence-based prioritisation resource.
Method
Plan-Do-Study-Act cycles and the Com-B model to influence behaviour changes were employed between October 2019 and March 2020. Stakeholders were engaged throughout the design process. Training to all 11 physiotherapists consisted of familiarisation with the resource through content discussion and “mock-use” training sessions to ensure intra/inter-rater-reliabilty. Physiotherapist staff knowledge and confidence of prioritisation was evaluated by questionnaire. Accuracy of use of the prioritisation tool was determined by comparison of staff prioritisation decision with expert opinion.
Results
From the 11 questionnaire responses, pre to post intervention physiotherapy knowledge of the prioritisation categories increased (43% to 100%), physiotherapist rated confidence using the prioritisation tool increased (mean score, 6.9 to 8.2/10) and accuracy of prioritisation of patients improved (mean 42.1% to 92.3%).
Conclusion
The education and training package developed to support implementation of the prioritisation tool resulted in improved staff knowledge and confidence of patient prioritisation and increased the accuracy of OPU physiotherapy targeting. This project has highlighted the importance of staff training in resource allocation to ensure that decisions regarding which patients receive physiotherapy intervention are efficacious. This has increased relevance in a department with a large number of rotational staff.

Abstract
Introduction The risk of severe morbidity after COVID-19 infection is high in older adults (Lithander et al, 2020). Subsequent responsive UK Government guidance for older adults included self-isolation during the pandemic. It is therefore hypothesised that during the pandemic older adults are inadvertently deconditioned due to iatrogenic factors such as inactivity, social isolation, hospital-avoidance and malnutrition, and present with reduced resilience to illness and lower levels of function. The OPU continued to admit COVID-negative, or recently termed “COVID-protected”, patients throughout the pandemic. Data captured prior to, and during the COVID-19 pandemic has been compared to explore the implications on older adults, and elicit whether they are protected from the consequences of the pandemic? Method Demographic and physical function data (average 6 m gait-speed, Elderly Mobility Scale) were captured pre- and through-pandemic for all patients admitted to a COVID-negative OPU ward over a one month period. Ethical review was provided through local Trust governance process. Results Pre-pandemic 2019 (n = 67, mean(±SD) age 82.7(±8.2) years, 61%, hospital length-of-stay (LOS) 7.9(±7.3) days, hospital mortality-rate 7.2%) and through-pandemic 2020 (n = 73, 83.1(±8.3) years, 59%♀, LOS 9.0(±9.1) days, hospital mortality-rate 7.5%) data were captured during July 2019 and May 2020 respectively. There were no between-group differences in age [t(−.313) = 138, p = 0.755], gender [X2, 1 df, p = 0.782], LOS [t(0.78) = 134, p = 0.44], or hospital mortality-rate [X2 1 df, p = 0.96]. Through-pandemic patients had a significantly slower 6 m gait-speed (0.11(±0.05) m.s-1) than pre-pandemic (0.16(±0.24) m.s-1); [t(2.74) = 93, p = 0.007] and lower median (IQR) Elderly Mobility Scale (4(6 IQR) vs 9 (12 IQR) [u = 866, p = 0.015]). Conclusion Our data indicates this relatively short period of self-isolation might have significant implications on the physical function of older adults. The likely mechanism is iatrogenic deconditioning. Critical Public Health and policy responses are required to mitigate these unforeseen risks by deploying prehabilitative counter-measures and accurately targeted hospital and community rehabilitation.

Abstract
Background Severe restrictions on in-person encounters and endoscopic procedures for digestive care have occurred as a result of the COVID-19 pandemic. This has exacerbated pre-existing barriers in access to gastroenterology (GI) care across Nova Scotia (NS) for patients and primary healthcare providers (PHCPs). In response, a provincial PHCP-GI consultative service (GUT LINK) was implemented at a single tertiary care center with the goal of supporting PHCPs in the management of non-urgent GI referral conditions. Aims To implement and evaluate the acceptability, feasibility, appropriateness, and early effectiveness of the GUT LINK PHCP-GI consultation service. Methods This is an ongoing prospective observational cohort study. All referrals received through the EMR-based referral and triage management system between May and November 2020 that were deemed to be amenable to management within primary care with specialist support were returned to the PHCP with the suggestion to arrange a GUT LINK telephone consultation. GUT LINK appointments were scheduled through an administrative support telephone line with the PHCP and a GI specialist. A post-consultation e-questionnaire was distributed to PHCPs who consented to participate. Feasibility (number of and indication for referrals, PHCP participation rates), acceptability and appropriateness (satisfaction, future use, likelihood to recommend) metrics and outcomes (case resolution, re-referrals, proportion requiring endoscopic investigations) were recorded. Patient charts were reviewed to determine whether the patient ultimately required GI speciality care. Analyses were descriptive and expressed as frequencies, means (+/-SD), medians (+/-SE), and proportions (%). Results A total of 45 GUT LINK consultations were completed between May and November 2020. Of these, 20% required GI specialist care and 80% have remained within primary care, with a median follow-up of 101 (+/-9.1) days. The indications for GUT LINK consultation included lower GI symptoms (64%), abnormal imaging or investigations (17%), and upper GI symptoms (19%). To date, 21 PHCP agreed to be contacted for the post-consultation survey and 10 have been completed. All PHCPs reported that GUT LINK consultation was easy to access, while 90% found the advice helpful and 80% reported that that it resolved the issue. Following the GUT LINK appointment, 80% felt they would not need to refer their patient to GI. Conclusions The implementation of GUT LINK was acceptable, feasible, and improved access to specialist support for management of undifferentiated GI symptoms. Future research will focus on comprehensive stakeholder engagement in order to design, implement, and evaluate GUT LINK PHCP care pathways. Funding Agencies CAG

Abstract
Abstract
Background
The COVID-2019 pandemic continues to restrict access to endoscopy, resulting in delays or cancellation of non-urgent endoscopic procedures. A delay in the removal or exchange of plastic biliary stents may lead to stent occlusion with consensus recommendation of stent removal or exchange at three-month intervals [1–4]. We postulated that delayed plastic biliary stent removal (DPBSR) would increase complication rates.
Aims
We aim to report our single-centre experience with complications arising from DPBSR.
Methods
This was a retrospective, single-center, observational cohort study. All subjects who had ERCP-guided plastic biliary stent placement in Halifax, Nova Scotia between Dec 2019 and June 2020 were included in the study. DPBSR was defined as stent removal >=90 days from insertion. Four endpoints were assigned to patients: 1. Stent removed endoscopically, 2. Died with stent in-situ (measured from stent placement to documented date of death/last clinical encounter before death), 3. Pending removal (subjects clinically well, no liver enzyme elevation, not expired, endpoint 1 Nov 2020), and 4. Complication requiring urgent reintervention. Kaplan-Meier survival analysis was used to represent duration of stent patency (Fig.1).
Results
102 (47.2%) had plastic biliary stents placed between 2/12/2019 and 29/6/2020. 49 (48%) were female, and the median age was 68 (R 16–91). Median follow-up was 167.5 days, 60 (58.8%) subjects had stent removal, 12 (11.8%) died before replacement, 21 (20.6%) were awaiting stent removal with no complications (median 230d, R 30–332), 9 (8.8%) had complications requiring urgent ERCP. Based on death reports, no deaths were related to stent-related complications.
72(70.6%) of patients had stents in-situ for >= 90 days. In this population, median time to removal was 211.5d (R 91-441d). 3 (4.2%) subjects had stent-related complications requiring urgent ERCP, mean time to complication was 218.3d (R 94–441). Stent removal >=90 days was not associated with complications such as occlusion, cholangitis, and migration (p=1.0). Days of stent in-situ was not associated with occlusion, cholangitis, and migration (p=0.57). Sex (p=0.275), cholecystectomy (p=1.0), cholangiocarcinoma (p=1.0), cholangitis (p=0.68) or pancreatitis (p=1.0) six weeks prior to ERCP, benign vs. malignant etiology (p=1.0) were not significantly associated with stent-related complications.
Conclusions
Plastic biliary stent longevity may have been previously underestimated. The findings of this study agree with CAG framework recommendations [5] that stent removal be prioritized as elective (P3). Limitations include small sample size that could affect Kaplan-Meier survival analysis. Despite prolonged indwelling stent time as a result of COVID-19, we did not observe an increased incidence of stent occlusion or other complications.

Abstract
Abstract
Background
The impacts of the COVID-19 pandemic have been far reaching and have necessitated many changes to healthcare delivery. At the QEII Health Sciences Center physical space limitations for patient check-in and recovery have restricted outpatient endoscopy to 3 of 4 available endoscopy suites. On June 1, 2020 a new system of central endoscopy triage and coordination for the Division of Digestive Care and Endoscopy (DC&E) was implemented in an effort to increase efficiency and maintain patient access to endoscopy. The components of the RESET (Re-introduce Endoscopy Safely and EfficienTly) Plan included a) a new endoscopy coordinator role to manage a common endoscopy waitlist, endoscopist schedules, and booking clerks, b) a modified triage system to improve waitlist consistency, c) a common endoscopy waitlist with patients booked in the next available appointment regardless of endoscopist, d) discontinuation of fixed endoscopy slots for endoscopists, and e) appointment scheduling no sooner than 4-weeks in advance to minimize no-shows and last-minute cancellations.
Aims
The aim of this study is to evaluate the impact of the RESET Plan on the efficiency of DC&E endoscopy.
Methods
A retrospective pre- and post-implementation study evaluating the volume and efficiency of outpatient endoscopy before and after implementation of the RESET Plan. The Pre-RESET period included all procedures performed from June 1, 2019 to October 31, 2019. The Post-RESET period included all procedures performed from June 1, 2020 to October 31, 2020. A separate endoscopy suite and triage system is used for endoscopic retrograde cholangiopancreatography (ERCP) and these cases were excluded. Early effectiveness outcomes were reported including a comparison of the number of endoscopic procedures per week and per list, pre- and post- implementation. Data analysis was primarily descriptive with data expressed as frequencies, means (SD), and proportions (%). Exploratory group comparisons were performed using independent-samples T-Test.
Results
During the 5-month Pre-RESET period, 2203 endoscopic procedures were performed. During the Post-RESET period a total of 1920 procedures were performed. Due to pandemic restrictions, there was a 29% decrease in available endoscopy lists from 2019 to 2020. There was a 24% increase in the number procedures performed per endoscopy list, from 6.4 to 8.0 (p=0.004, 95% CI 0.52–2.53), pre- and post-RESET.
Conclusions
While the COVID-19 pandemic has disrupted healthcare delivery, it has also provided an opportunity to implement health system structure and process changes. The RESET Plan resulted in significant gains in efficiency which largely offset losses in endoscopy throughput imposed by COVID-19 pandemic restrictions. Future research will determine what patient and health system factors most significantly impact system efficiency as well as the cost-effectiveness of the RESET Plan.

Abstract
Background The global COVID-19 pandemic has resulted in a dramatic re-alignment of clinical service delivery. In mid-March 2020 the Division of Digestive Care and Endoscopy at Dalhousie University leveraged eHealth technology to rapidly implemented a new referral management and triage system and established a new rapid outpatient consultation service to facilitate urgent virtual and face-to-face appointments. Standardized procedures for triaging, booking, and staffing the urgent gastroenterology consultation service were implemented. Aims The aim of this study was to evaluate the impact of the implementation of a standardized triage and consultation process on access to urgent gastroenterology consultative services at a single tertiary care center during the COVID-19 pandemic. Methods We performed a pre- and post-implementation study comparing efficiency metrics for urgent triage and urgent consultation. The pre-implementation cohort included all patients referred and triaged to an urgent clinic appointment between April 1, 2019 to September 30, 2019. The post-implementation cohort included all patients referred and triaged to an urgent clinic appointment between April 1, 2020 to September 30, 2020. Healthcare efficiency data was extracted through electronic record review with specific dates and times for referral receipt (a), triage completion (b), appointment wait-listing (c), and clinic appointment (d). The time to triage (TT), time to visit (TV), and total time to consult (TC) were calculated (TT = c - a; TV = d - c; TC = TT + TV) for each patient. The Mann–Whitney U test was used to compare TT, TV, CT between patient cohorts. Results A total of 429 patients were booked for urgent clinic consultation, 176 during the pre-implementation period and 253 in the post-implementation period. The mean TT for the pre-and post-implementation cohorts was 4.8 days and 3.3 days, respectively (U=18,149, p=0.001). Mean TV was decreased from 16.2 days for the pre-implementation cohort to 3.6 days for the post-implementation cohort (U=6095, p=0.000). The mean time from a referral being received to the patient being seen in consultation (TC) decreased by 67% from 21 days to 6.9 days, Figure 1 (U=6,419, p=0.000). Conclusions The COVID-19 pandemic has had a dramatic impact on healthcare delivery in Nova Scotia. One positive result is that it facilitated the motivation and alignment needed to make a large health system change that may not have otherwise been possible. This study demonstrates that a standardized pathway for urgent outpatient gastroenterology assessment improves the timeliness of care delivery. ![]()

The effect of lifestyle and risk factor modification on occlusive peripheral arterial disease outcomes: standard healthcare vs structured programme-for a randomised controlled trial protocol. Trials 2021; 22:138. [PMID: 33581715 PMCID: PMC7881542 DOI: 10.1186/s13063-021-05087-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Accepted: 02/01/2021] [Indexed: 11/10/2022] Open
Abstract
Background Peripheral arterial disease (PAD) affects more than 200 million of the global population. PAD represents a marker for premature cardiovascular events. Patients with PAD, even in the absence of a history of myocardial infarction or ischemic stroke, have approximately the same relative risk of death from cardiovascular causes as patients with a history of coronary or cerebrovascular disease. Despite the high prevalence of PAD and the strong association with cardiovascular morbidity and mortality, patients with PAD are less likely to receive appropriate treatment for their atherosclerotic risk factors than those who are being treated for coronary artery disease. Atherosclerotic risk factor identification and modification play an important role in reducing the number of adverse outcomes among patients with atherosclerosis. Risk reduction therapy decreases the risk of cardiovascular mortality and morbidity in patients with PAD. In this study, we aim to evaluate the effectiveness of a lifestyle and risk factor modification intervention programme in achieving treatment goals for PAD risk factors. Methods This is a randomised, parallel group, active-control trial to compare the effectiveness of the risk factor modification intervention programme to standard healthcare in a tertiary vascular care centre, in the reduction of modified risk factors in PAD patients. The primary outcome of this study is to evaluate the effectiveness of a lifestyle and risk factor modification intervention programme in achieving treatment goals for PAD risk factors at 3 and 12 months. The secondary outcomes are to compare the impact of the programme on clinical outcomes in PAD patients at 12 months. Secondary outcomes include amputation-free survival, clinical improvement, haemodynamic improvement, need for revascularisation procedures, outcomes of revascularisation procedures, changes in quality of life and the incidence of adverse events. Discussion This study will provide clear evidence on the effectiveness of a lifestyle and risk factor modification intervention programme in achieving treatment goals for PAD risk factors, through a high-quality, well-powered clinical trial. Trial registration This trial was registered (11/07/2017) on the European Clinical Trials Database (EudraCT number 2017-002964-41) and ClinicalTrials.gov (NCT03935776) which was registered on 02 May 2019.

Abstract
This paper presents the first plasmid DNA irradiations carried out with Very High Energy Electrons (VHEE) over 100-200 MeV at the CLEAR user facility at CERN to determine the Relative Biological Effectiveness (RBE) of VHEE. DNA damage yields were measured in dry and aqueous environments to determine that ~ 99% of total DNA breaks were caused by indirect effects, consistent with other published measurements for protons and photons. Double-Strand Break (DSB) yield was used as the biological endpoint for RBE calculation, with values found to be consistent with established radiotherapy modalities. Similarities in physical damage between VHEE and conventional modalities gives confidence that biological effects of VHEE will also be similar-key for clinical implementation. Damage yields were used as a baseline for track structure simulations of VHEE plasmid irradiation using GEANT4-DNA. Current models for DSB yield have shown reasonable agreement with experimental values. The growing interest in FLASH radiotherapy motivated a study into DSB yield variation with dose rate following VHEE irradiation. No significant variations were observed between conventional and FLASH dose rate irradiations, indicating that no FLASH effect is seen under these conditions.

Abstract
BACKGROUND Prevalence of depression is increasing in young people, and there is a need to develop and evaluate behavioural interventions which may provide benefits equal to or greater than talking therapies or pharmacological alternatives. Exercise could be beneficial for young people living with depression, but robust, large-scale trials of effectiveness and the impact of exercise intensity are lacking. This study aims to test whether a randomised controlled trial (RCT) of an intervention targeting young people living with depression is feasible by determining whether it is possible to recruit and retain young people, develop and deliver the intervention as planned, and evaluate training and delivery. METHODS The design is a three-arm cluster randomised controlled feasibility trial with embedded process evaluation. Participants will be help-seeking young people, aged 13-17 years experiencing mild to moderate low mood or depression, referred from three counties in England. The intervention will be delivered by registered exercise professionals, supported by mental health support workers, twice a week for 12 weeks. The three arms will be high-intensity exercise, low-intensity exercise, and a social activity control. All arms will receive a 'healthy living' behaviour change session prior to each exercise session and the two exercise groups are energy matched. The outcomes are referral, recruitment, and retention rates; attendance at exercise sessions; adherence to and ability to reach intensity during exercise sessions; proportions of missing data; adverse events, all measured at baseline, 3, and 6 months; resource use; and reach and representativeness. DISCUSSION UK National Health Service (NHS) policy is to provide young people with advice about using exercise to help depression but there is no evidence-based exercise intervention to either complement or as an alternative to medication or talking therapies. UK National Institute for Health and Care Excellence (NICE) guidelines suggest that exercise can be an effective treatment, but the evidence base is relatively weak. This feasibility trial will provide evidence about whether it is feasible to recruit and retain young people to a full RCT to assess the effectiveness and cost-effectiveness of an exercise intervention for depression.

Abstract
Context
Overseas studies have quantified production differences of Hereford × Angus compared with purebred Angus for a range of traits including growth, carcass and reproductive traits.
Aim
This study aims to provide a comparison of Hereford × Angus and purebred Angus under modern grazing conditions in southern Australia.
Methods
Thirty Hereford and 22 Angus sires were mated to 1100 Angus cows and heifers in a large commercial herd run on pasture at Musselroe Bay, Tasmania. Approximately 1650 calves were born. Steers were grown on pasture for an average of 23 months and then slaughtered.
Results
Hereford sired calves were heavier at birth (+8.8%) and weaning (+4.1%). Hereford-sired calves from heifers (but not from mature cows) had more assisted births (+8.2%) and more calf deaths (10.0% vs 5.1%). Hereford-sired steers had higher hot standard carcass weight (+4.1%) and eye-muscle area (+3.2%) but when hot standard carcass weight was fitted as a covariate, eye-muscle area was no longer significant. Carcass quality measures (AUSMEAT marbling –25.8%, Meat Standards Australia marbling –10.5%, Meat Standards Australia index –1.0%) were poorer for Hereford-sired steers and fat colour (+6.9%) was darker. Meat samples from Hereford-sired steers had significantly lower colour indicators (L and b). There was no difference in cooking loss and shear force, and intramuscular fat was lower (3.0% vs 4.1%).
Conclusions
Hereford × Angus calves were heavier at birth than were purebred Angus, but had more calving difficulty and deaths associated with heifer dams. Hereford × Angus carcasses were heavier but had lower indicators of quality than did purebred Angus.
Implications
As Hereford × Angus steers produced a 4.1% heavier carcass, pure Angus steers would need to attract a premium of at least 4.1% for the additional marbling to give more value. Hereford bulls could be mated to Angus cows and not Angus heifers to avoid calving difficulties. Alternatively, good calving Hereford bulls could be selected using estimated breeding values when mating to Angus heifers.

Abstract
OBJECTIVE To conduct patient and public involvement (PPI) to gain insight into the experience of healthy eating and weight management advice during pregnancy. DESIGN PPI in the planning and development of health interventions, aiming to ensure patient-centred care. Optimum nutrition and weight management are vital for successful pregnancy outcomes, yet many services report poor attendance and engagement. SETTING Community venues in Liverpool and Ulster (UK). PARTICIPANTS Two PPI representatives were involved in all aspects of the study: design, interview questions, recruitment and collection/analysis of feedback. INTERVENTION Feedback was collected via note taking during group discussions, two in Liverpool (n = 10 & 5); two in Ulster (n = 7 & 9) and an interview (n = 1, in Ulster). MAIN OUTCOME MEASURES Transcript data were collated and thematic analysis was applied in analysis. RESULTS Thematic analysis identified three themes: (i) weight gain is inevitable in pregnancy; (ii) healthy eating advice is important but currently lacks consistency and depth and (iii) expectations regarding the type of knowledge/support. CONCLUSIONS PPI provides opportunity to enhance research design and offers valuable insight towards the needs of healthcare users. Pregnant women want positive health messages, with a focus on what they can/should do, rather than what they should not do. Midwives need to consider their communication with pregnant women, to ensure that their unique relationship is maintained, especially when the topics of diet and weight management are addressed. A well-designed digital intervention could improve access to pregnancy-specific nutrition information; empowering midwives to communicate patient-centred, healthy eating messages with confidence. This has the potential to change dietary and weight management behaviour in pregnant women.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (cSCC) is a common cancer that invades the dermis through the basement membrane. The role of the basement membrane in poorly differentiated cSCC is not well understood. OBJECTIVES To study the effect that loss of the laminin subunit alpha-3 (α3) chain from the tumour microenvironment has on tumour invasion and inflammatory cell recruitment. METHODS We examined the role of the basement membrane proteins laminin subunits α3, β3 and γ2 in SCC invasion and inflammatory cell recruitment using immunohistochemistry, short hairpin RNA knockdown, RNA-Seq, mouse xenograft models and patient tumour samples. RESULTS Analysis of SCC tumours and cell lines using antibodies specific to laminin chains α3, β3 and γ2 identified a link between poorly differentiated SCC and reduced expression of laminin α3 but not the other laminin subunits investigated. Knockdown of laminin α3 increased tumour invasion both in vitro and in vivo. Western blot and immunohistochemical staining identified increased phosphorylated myosin light chain with loss of laminin α3. Inhibition of ROCK (rho-associated protein kinase) but not Rac1 significantly reduced the invasive potential of laminin α3 knockdown cells. Knockdown of laminin subunits α3 and γ2 increased monocyte recruitment to the tumour microenvironment. However, only the loss of laminin α3 correlated with increased tumour-associated macrophages both in xenografted tumours and in patient tumour samples. CONCLUSIONS These data provide evidence that loss of the laminin α3 chain in cSCC has an effect on both the epithelial and immune components of cSCC, resulting in an aggressive tumour microenvironment.

Abstract
Volcanic emissions are a critical pathway in Earth's carbon cycle. Here, we show that aerial measurements of volcanic gases using unoccupied aerial systems (UAS) transform our ability to measure and monitor plumes remotely and to constrain global volatile fluxes from volcanoes. Combining multi-scale measurements from ground-based remote sensing, long-range aerial sampling, and satellites, we present comprehensive gas fluxes-3760 ± [600, 310] tons day-1 CO2 and 5150 ± [730, 340] tons day-1 SO2-for a strong yet previously uncharacterized volcanic emitter: Manam, Papua New Guinea. The CO2/ST ratio of 1.07 ± 0.06 suggests a modest slab sediment contribution to the sub-arc mantle. We find that aerial strategies reduce uncertainties associated with ground-based remote sensing of SO2 flux and enable near-real-time measurements of plume chemistry and carbon isotope composition. Our data emphasize the need to account for time averaging of temporal variability in volcanic gas emissions in global flux estimates.

Abstract
Postoperative pain is an outcome of importance to potential living kidney donors (LKDs). We prospectively characterized the prevalence, severity, and patterns of acute or chronic postoperative pain in 193 LKDs at six transplant programs. Three pain measurements were obtained from donors on postoperative Day (POD) 1, 3, 7, 14, 21, 28, 35, 41, 49, and 56. The median pain rating total was highest on POD1 and declined from each assessment to the next until reaching a median pain-free score of 0 on POD49. In generalized linear mixed-model analysis, the mean pain score decreased at each pain assessment compared to the POD3 assessment. Pre-donation history of mood disorder (adjusted ratio of means [95% confidence interval (CI)]: 1.40 [0.99, 1.98]), reporting "severe" on any POD1 pain descriptors (adjusted ratio of means [95% CI]: 1.47 [1.12, 1.93]) and open nephrectomy (adjusted ratio of means [95% CI]: 2.61 [1.03, 6.62]) were associated with higher pain scores across time. Of the 179 LKDs who completed the final pain assessment, 74 (41%) met criteria for chronic postsurgical pain (CPSP), that is, any donation-related pain on POD56. Study findings have potential implications for LKD education, surgical consent, postdonation care, and outcome measurements.

Abstract
BACKGROUND Mozambique has one of the highest incidence rates of both TB and HIV in the world and an estimated tuberculosis (TB) treatment coverage of only 57% in 2018. Numerous approaches are being tested to reduce existing gaps in coverage and the estimated number of missing cases. METHODS Thirty Community Healthcare Workers (CHWs) were tasked with increasing TB notifications by performing verbal facility-based TB screening of all people presenting for care and TB contact tracing in the community. Using routine National TB Program data, we analyzed trends in TB notifications in five intervention districts and seven control districts in Manica province the year before this project and during a one-year intervention period. RESULTS In the four quarters before the study, the intervention districts notified 5,219 individuals with all forms of TB, and the control districts notified 2,248 TB cases. During the study 5,982 all forms of people with TB were notified in the intervention area, an increase of 763 (14.6%) over the baseline, whereas the control districts notified 1,877 persons with TB, a decrease of -371 (-16.5%). The CHW screening activities yielded 1,502 notified and treated individuals with TB. CONCLUSIONS Employing CHWs to promote facility-based TB screening and household contact tracing may lead to an overall increase in TB notification.

Abstract
The Vitamin D External Quality Assessment Scheme (DEQAS) distributes serum samples globally, on a quarterly basis, to assess participants' performance of specific methods for 25-hydroxyvitamin D (25OHD) and 1,25-dihydroxyvitamin D (1,25-(OH)2D). DEQAS occasionally circulates samples containing high levels of substances found in certain clinical situations e.g. 25-OHD2, 24,25-(OH)2D3, hypertriglyceridemia. The increased availability and use of health supplements containing biotin has led to case reports of assay interference in methods utilizing a biotin-streptavidin detection system. In October 2018, DEQAS included a serum sample (545) containing exogenous biotin (concentration =586 μg/L) which was analyzed by a total of 683 laboratories using 35 different methods. The same serum sample (544) without exogenous biotin was also included in the 5-sample set. All methods (760 laboratories) performed satisfactorily on sample 544 giving an All-Laboratory Trimmed Mean = 50.2 ± 6.5 nmol/L (±SD, CV = 12.9 %). The target value for this sample 544 (& 555) was 47.4 nmol/L as determined by Centers for Disease Control and Prevention (CDC) Atlanta, Georgia using their LC-MS/MS reference method. In contrast, #545 containing the exogenous biotin was reported by only 683 laboratories and gave an All-Laboratory Trimmed Mean = 66.8 ± 37.6 nmol/L (±SD, CV = 56.3 %). As expected, LC-MS/MS methods (143 labs) reported similar results for both 544 = 48.9 ± 4.4 nmol/L (±SD) and 545 = 48.3 ± 4.5 nmol/L (±SD) showing that assays involving chromatographic steps are unaffected by the presence of biotin. Several of the antibody-based assays including Abbott Architect, DiaSorin Liaison, Beckman Unicel and Siemens Centaur are also unaffected by the addition of biotin. Two assays, IDS-iSYS and Roche Total 25OHD, both of which use biotin-streptavidin, exhibit biotin interference yielding values with a significant positive bias for 545 of 102.6 nmol/L ± 78.7 nmol/L (±SD) and 517.8 nmol/L ± 209.8 nmol/L (±SD) respectively. Interestingly, the failure to report sample 545 data from 77 laboratories is due solely to those running Roche Total 25OHD or Roche Vitamin D Total II assays. Given the prevalence of the adversely affected assays (25 % of DEQAS users) and the high volume of 25OHD testing, clinicians using these assays should, where possible, only measure 25OHD when patients are off biotin.

Abstract
BACKGROUND Due to the high incidence and demographic development, there is an urgent need for healthcare research data on lower urinary tract symptoms due to benign prostatic hyperplasia (LTUS/BPH). Since 2005 the Governing Body of German Prostate Centers (DVPZ) has been collecting data from 22 prostate centers in order to determine the quality and type of cross-sectoral care in particular for LUTS/BPH patients. OBJECTIVES Presentation of the DVPZ database in general, as well as an investigation of treatment patterns for medical and instrumental therapies. MATERIALS AND METHODS The analysis is based on UroCloud data sets from 30 November 2017. In the UroCloud data on diagnostics, therapy and course of disease are recorded in a web-based manner. RESULTS A total of 29,555 therapies were documented for 18,299 patients (1.6/patient), divided into 48.5% instrumental, 29.2% medical treatment, and 18.0% "wait and see" (in 4.3% no assignment was possible). Patients treated with an instrumental therapy were oldest (median: 72 years, interquartile range: 66-77), had the largest prostate volumes (50 ml, 35-75 ml), and were mostly bothered by symptoms (International Prostate Symptom Score = 19/4). The majority of patients under medical treatment received alphablockers (56%); phytotherapeutics were used least frequently (3%). Instrumental therapies are dominated by transurethral resection (TUR) of the prostate (60.0%), open prostatectomy (9.4%) and laser therapy (5.0%), with laser therapy having the shortest hospital stay (5 days) and the lowest transfusion and re-intervention rates (1.0% and 4.6%, respectively). CONCLUSIONS The DVPZ certificate covers the complete spectrum of cross-sectoral care for LUTS/BPH patients and documents the use of the various therapies as well as their application and effectiveness in the daily routine setting.

Abstract
Background In the ongoing debate on optimum methods for identification of Indigenous people within linked administrative data, few studies have examined the impacts of method on population counts and outcomes in family-based linkage studies of Aboriginal children. Objective To quantify differences between three algorithms in ascertaining Aboriginal and Torres Strait Islander children in linked administrative data. Methods Linked administrative health data for children born in Western Australia (WA) from 2000-2013, were used to examine the cohorts identified by three methods: A) the Indigenous Status Flag (ISF, derived by the WA Data Linkage Branch using a multistage-median approach) for the children alone; B) the ISF of the children, their parents and grandparents; and C) Indigenous status of the child, mother or father on either of the child's perinatal records (Midwives or birth registration), to determine differing characteristics of each cohort. Results Method B established a larger cohort (33,489) than Method C (33,306) and Method A (27,279), with all methods identifying a core group of 26,790 children (80-98%). Compared with children identified by Method A, additional children identified by Methods B or C, were from less-disadvantaged and more urban areas, and had better perinatal outcomes (e.g. lower proportions of small-for-gestational age, 10% vs 16%). Differences in demographics and health outcomes between Methods C and B were minimal. Conclusions Demographic and perinatal health characteristics differ by Aboriginal identification method. Using perinatal records or the ISF of parents and grandparents (in addition to the ISF of the child) appear to be more inclusive methods for identifying young Indigenous children in administrative datasets. Keywords Aboriginal health, identification, data linkage, Indigenous, child, methodology.
