Abstract
Many populations migrate between two different habitats (e.g. wintering/foraging to breeding area, mainstem-tributary, river-lake, river-ocean, river-side channel) as part of their life history. Detection technologies, such as passive integrated transponder (PIT) antennas or sonic receivers, can be placed at boundaries between habitats (e.g. near the confluence of rivers) to detect migratory movements of marked animals. Often, these detection systems have high detection probabilities and detect many individuals but are limited in their ability to make inferences about abundance because only marked individuals can be detected. Here, we introduce a mark-recapture modelling approach that uses detections from a double-array PIT antenna system to imply movement directionality from arrays and estimate migration timing. Additionally, when combined with physical captures, the model can be used to estimate abundances for both migratory and non-migratory groups and help quantify partial migration. We first test our approach using simulation, and results indicate our approach displayed negligible bias for total abundance (less than ±1%) and slight biases for state-specific abundance estimates (±1%-6%). We fit our model to array detections and physical captures of three native fishes (humpback chub [Gila cypha], flannelmouth sucker [Catostomus latipinnis] and bluehead sucker [Catostomus discobolus]) in the Little Colorado River (LCR) in Grand Canyon, AZ, a system that exhibits partial migration (i.e. includes residents and migrants). Abundance estimates from our model confirm that, for all three species, migratory individuals are much more numerous than residents. There was little difference in movement timing between 2021 (a year without preceding winter/spring floods) and 2022 (a year with a small flood occurring in early April). In both years, flannelmouth sucker arrived in mid-March whereas humpback chub and bluehead sucker arrivals occurred early- to mid-April. With humpback chub and flannelmouth sucker, movement timing was influenced by body size so that large individuals were more likely to arrive early compared to smaller individuals. With more years of data, this model framework could be used to evaluate ecological questions pertaining to flow cues and movement timing or intensity, relative trends in migrants versus residents and ecological drivers of skipped spawning.

Abstract
The American Association of Physicists in Medicine (AAPM) recently published the report of Task Group (TG) 302, which provides recommendations on acceptance, commissioning, and ongoing routine quality assurance (QA) for surface-guided radiation therapy (SGRT) systems. One of the recommended monthly QA tests is a dynamic localization accuracy test. This work aimed to develop an automated procedure for monthly SGRT dynamic localization QA. An anthropomorphic head phantom was rigidly attached to the 6-dof couch of a TrueBeam linac. TrueBeam Developer Mode was used to take an MV image of the phantom at the starting position, then automatically drive the couch through a series of translations and rotations, taking an MV image after each translation. The Identify SGRT system monitored the motion of the phantom surface from the starting position. Translations assessed on MV images were compared to translations reported in trajectory log files and Identify log files. Rotations were compared between trajectory log files and Identify log files. Three experiments were conducted. None of the translations or rotations from any experiment exceeded the tolerance values for stereotactic ablative body radiation therapy (SABR) recommended by AAPM TG-142. Maximum deviations from the expected translation values from MV imaging, trajectory log files, and Identify log files were -0.94mm, -0.11mm, and -0.78mm, respectively. Maximum deviations from the expected rotation values from trajectory log files and Identify log files were 0.01 and -0.2 degrees, respectively. The proposed method is a simple automated way to complete monthly dynamic localization QA of SGRT systems.

Abstract
The purpose of this study was to address the variability in quality of magnetic resonance cholangiopancreatography (MRCP) images by examining differences in quality grades before and after modifying the MRCP protocol to include placement of physical bellows while scanning. This single institution quality improvement initiative included 727 MRCP examinations performed from July 2019 to December 2020 in patients 18 years and older. The Define, Measure, Analyze, Improve, and Control (DMAIC) strategy was utilized to explore factors related to MRCP image quality and identify solutions that could create effective change. Based on the results of this analysis, MRCP protocols were changed in December 2019 to include physical bellows. Examinations were grouped as occurring either pre- or postintervention as well as whether they occurred in an inpatient or outpatient setting. MRCP examinations were evaluated for quality and labeled either nondiagnostic or diagnostic. A logistic regression model was fit to compare the odds of a diagnostic QA grade between preintervention and postintervention groups and inpatient and outpatient settings. The preintervention group had 41.12% of MRCP studies of diagnostic quality, and the postintervention group had 60.57% of studies of diagnostic quality. The estimated odds of an image being of diagnostic quality in the postintervention group were 2.46 times the odds for the preintervention group across all departments and patient classes (P < 0.001). The estimated odds of an image being of diagnostic quality in the outpatient group were 2.01 times the odds for those in the inpatient group (P < 0.001). Utilizing a standardized quality improvement method can lead to sustained improvements in the diagnostic quality of MRCP studies.

Abstract
Abstract
Background
Pregnancy related cardiomyopathy is a significant cause of maternal morbidity and mortality globally. A presumed overlap between normal pregnancy-associated symptoms and clinical symptoms of cardiomyopathy contributes to delays in diagnosis and increased risk of maternal mortality.
Purpose
We sought to evaluate the association between patient-reported cardiovascular symptoms and the presence of cardiomyopathy among pregnant and postpartum patients. We hypothesize that individual cardiovascular symptoms are unrelated to the presence of cardiomyopathy. We also evaluated the use of a novel adaptation of a validated health status questionnaire in relation to cardiomyopathy.
Methods
We enrolled 48 pregnant (>13 weeks) and postpartum (up to 12 months) participants in a prospective study between October 2021 and February 2022. All study participants completed a baseline questionnaire, which included current cardiovascular symptoms, an assessment of health status using an adapted version of the Kansas City Cardiomyopathy Questionnaire (KCCQ-12), followed by a resting transthoracic echocardiogram on the same day. We defined cardiomyopathy as a left ventricular ejection fraction (LVEF) <50% based on 2-D echocardiography. Fisher's exact and Wilcoxon rank-sum tests were employed to evaluate the association between reported cardiovascular symptoms, the adapted KCCQ-12 (KCC-A) score, and cardiomyopathy.
Results
At the time of enrollment, 67% were pregnant and 33% postpartum. Forty-eight percent identified as White, 31% as Black, 10% as Asian, and 10% as other race. The median age was 31 years (Q1: 28, Q3: 35) and 6% had an LVEF <50%. We found no statistically significant association between four reported cardiovascular symptoms (shortness of breath, orthopnea, fast breathing, and episodes of “asthma” that did not improve with inhalers or other treatment) and cardiomyopathy or medial E/e' ratio. KCC-A scores were low in the study population overall (median 52; Q1:40, Q3: 61). We demonstrated a significantly lower KCC-A score among women with LVEF <50% (median 24; Q1: 15, Q3: 44) compared to women with LVEF ≥50% (median 54; Q1: 44, Q3: 61) p=0.02.
Conclusions
We showed no significant association between individual cardiovascular symptoms and cardiomyopathy in an obstetric population. However, we demonstrate for the first time that an adapted KCCQ-12 questionnaire for health status assessment could potentially identify women with a high-likelihood of cardiomyopathy during the peripartum period who may benefit from additional evaluation including echocardiography. Larger studies are needed to validate this finding.

Abstract
AIMS People living with treatable but not curable cancer often experience a range of symptoms related to their cancer and its treatment. During the COVID-19 pandemic, face-to-face consultations were reduced and so remote monitoring of these needs was necessary. University Hospitals Sussex implemented the routine use of electronic remote patient-reported outcome measures (PROMs) in a mixed oncology population, focusing on those with treatable but not curable cancers. MATERIALS AND METHODS Over a 9-month period, patients were invited to register with My Clinical Outcomes (MCO) - a secure online platform for the collection of electronic PROMs. They were prompted by e-mail to complete assessments (EORTC QLQ-C30, EQ-5D-3L and EQ-5D VAS) routinely every 2 weeks. The team monitored patient scores and changes in these prompted clinical interventions. RESULTS In total, 324 patients completed at least one assessment. The median number of assessments completed by each patient was eight. The most represented tumour groups were secondary breast (28%), prostate (25%) and other (32%). Median scores for the assessments did not deteriorate in a clinically or numerically significant way for patients living with non-curable conditions for the majority of patients monitored. CONCLUSION Routine collection of electronic remote PROMs is an effective and useful strategy to provide real-time clinical feedback to teams. With integration into existing systems, online platforms (such as MCO) could provide efficient and patient-centred information for those providing care for people with cancer.

Abstract
An asymptomatic 25-year-old G4P0120 with history significant for cervical insufficiency and classical cesarean delivery 12.5 months prior to conception underwent routine transabdominal ultrasound at 36w4d; umbilical cord was found to be protruding into a fluid-filled pouch extruding from the lower uterine segment. During emergent cesarean delivery, a full-thickness uterine rupture was confirmed; the fetal cranium and umbilical cord were extrauterine. Maternal genotype revealed greater than expected minor allele frequencies for several collagen genes. Maternal gene expression (mRNA) and corresponding microRNA expression of these collagen genes differed several-fold between her G3 (cervical insufficiency, classical cesarean delivery) and G4 (uterine rupture) pregnancies. This case highlights that (1) cervical insufficiency, poor myometrial wound healing, and uterine rupture may co-occur and pathophysiology may be related to collagen abnormalities and (2) asymptomatic uterine rupture can be detected sonographically, even in late pregnancy. Clinicians should remain vigilant for the possibility of uterine rupture, particularly among high-risk patients.

Abstract
Breast biomechanics, exercise-induced breast pain (EIBP) and performance effects in female athletes are established. Wearing sports bras during exercise reduces breast movement and EIBP. Despite the prevalence of female equestrians, little investigation of breast movement during horse riding exists, yet excessive breast movement, embarrassment and EIBP are reported. Breast movement relative to the torso is linked to EIBP, associated with magnitude and direction of forces generated. Equestrians may experience novel breast and upper-body movement patterns in response to large vertical excursions of the horse. This study aimed to establish relative vertical breast displacement (RVBD), EIBP and positional changes in three support conditions: ‘no support’, ‘low support’ and ‘high support’. Thirty-eight female equestrians rode a Racewood™ Equine Simulator in each breast support condition in medium walk, medium trot (sitting) and medium canter. Trials were filmed and analysed using Quintic® Biomechanics V29. Significant reductions in RVBD (P<0.001) and EIBP (P<0.001) were identified with increased breast support in all gaits. In medium trot (sitting) a significant reduction in range of movement (ROM) of shoulder-elbow-wrist (P<0.001) was seen from low to high support. ROM of torso-vertical angles were reduced from no support to low support (P<0.001) and further by high support (P<0.001). This reduction in ROM was significantly greater in large breasted riders (cup size DD-FF) (n=21) (P<0.001) compared to small breasted (cup size AA-D) (n=17). These results suggest that appropriate breast support positively impacts EIBP and riding position in female riders possibly enhancing performance. As RVBD and reported EIBP were not wholly comparative with results in female runners, further research is warranted to establish breast movement in equestrianism in three dimensions.

Adult and paediatric rheumatology trainees worldwide in training in 2020 were invited to participate via social media and email. Using multiple choice questions, Likert scales, and free text answers, we assessed trainee patient care activities, redeployment, research, and well-being.Results:The 302 respondents were from 33 countries, with most (83%, 252/302) in adult rheumatology training. Many trainees (45%, 135/300) reported an increase in non-rheumatology clinical work (e.g. care of COVID-19 patients), with 52% of these (70/135) also continuing rheumatology clinical work. COVID-19 redeployment was not optional for 68% (91/134).Trainees reported a negative impact of the pandemic in their growth in rheumatology (Figure 1). They also reported a substantial impact on several training areas: outpatient clinics (79%, 238/302), inpatient consultations (59%, 177/302), formal teaching (55%, 167/302), procedures (53%, 147/302), teaching opportunities (52%, 157/302), and ultrasonography (36%, 110/302), with 87-96% perceiving a negative impact on these areas. Only 54% (159/294) reported feeling comfortable with their level of clinical supervision during the pandemic (Figure 1).Many trainees (46%, 128/280) reported changes in research experiences during the pandemic; 39% (110/285) reported that COVID-19 negatively affected their ability to continue their pre-pandemic research and 50% (142/285) reported difficulty maintaining research goals (Figure 1).Some rheumatology trainees reported having health condition(s) putting them at high risk for COVID-19 (10%, 30/302) and 14% of trainees (41/302) reported having had COVID-19 (Table 1). Only 53% (160/302) reported feeling physically safe in the workplace while 25% (76/302) reported not feeling physically safe; reasons included lack of training about COVID-19, lack of comfort in the clinical setting, insufficient personal protective equipment, immunocompromised state, and pregnancy. Half (151/302) reported burnout and 68% (204/302) an increase in stress from work during the pandemic (Figure 1), whilst 25% (75/302) reported that changes to their training programme negatively impacted their physical health.Conclusion:The COVID-19 pandemic has negatively impacted the experience of rheumatology training as well as the well-being of trainees globally. Our data highlight concerns for rheumatology trainees including research opportunities and clinical care which should be a focus for curriculum planning.Figure 1.Rheumatology trainee perceptions of pandemic impact and changes in training programme.Table 1.Estimated hazard ratios, adjusted for age and gender, for individuals with rheumatoid arthritisEuropen = 89ROWn = 213Combinedn = 302Disability1 (1)9 (4)10 (3)High risk7 (8)23 (11)30 (10)Pregnant4 (5)15 (7)19 (6)Shielding/Quarantining12 (13)70 (33)82 (27)Acquired COVID-1920 (22)21 (10)41 (14)Disclosure of Interests:Kristen Young: None declared, Su-Ann Yeoh: None declared, Michael Putman: None declared, Elizabeth Graef: None declared, Francis Berenbaum: None declared, Richard Conway: None declared, Rebecca Grainger Speakers bureau: Speaker fees from Abbvie, Janssen, Novartis, Pfizer, Cornerstones, all not related to this work, Consultant of: Consultancy fees from Abbvie, Janssen, Novartis, Pfizer, Cornerstones, all not related to this work, Grant/research support from: Travel assistance from Pfizer, not related to this work, Adam Kilian: None declared, Maximilian Konig: None declared, Jean Liew Grant/research support from: Research grant from Pfizer unrelated to this manuscript, Pedro M Machado Speakers bureau: Speaker fees from Abbvie, BMS, Celgene, Eli Lilly, Janssen, MSD, Novartis, Orphazyme, Pfizer, Roche and UCB, all unrelated to this manuscript, Consultant of: Consulting fees from Abbvie, BMS, Celgene, Eli Lilly, Janssen, MSD, Novartis, Orphazyme, Pfizer, Roche and UCB, all unrelated to this manuscript, Sebastian E.

Abstract
Background:The COVID-19 pandemic led to a rapid increase in remote consultations in rheumatology care. Due to the potential impact of this change on rheumatology clinical training, we investigated trainees’ experiences with telemedicine.Objectives:To assess the impact of telemedicine use during the COVID-19 pandemic on rheumatology training, including supervision.Methods:A voluntary, anonymous web-based survey was administered in English, Spanish, or French from 19/08/2020 to 05/10/2020. Adult and paediatric rheumatology trainees worldwide in training in 2020 were invited to participate via social media and email. Using multiple choice questions, Likert scales, and free text answers, we collected data regarding prior and current telemedicine use, training, and supervision.Results:302 respondents from 33 countries completed the survey, with most (83%, 252/302) in adult rheumatology training. Reported use of telemedicine increased from 13% (39/302) pre-pandemic to 82% (247/302) (Table 1). European trainees predominantly utilised audio-only compared to trainees from the rest of the world (ROW) who predominantly utilised audio-video telemedicine.Most trainees continued to evaluate new patients using telemedicine (65%, 161/247). A larger proportion of trainees were comfortable using telemedicine to evaluate follow-up (69% 170/247) versus new patients (25%, 41/161) (Figure 1).Only 32% (97/302) were trained in telemedicine, with the highest proportion among United States (US) trainees (59%, 69/116); subjects included software, clinical skills, and billing. The majority of trainees found this helpful (92%, 89/97).Supervision was most frequently in the form of verbal discussion after the consultation (Table 1); 24% (59/247) had no telemedicine supervision during the pandemic. In general, trainees found telemedicine negatively impacted their supervision (51%, 123/242) and clinical teaching quality (70%, 171/244); only 9% reported a positive impact on these areas.Conclusion:Adoption of telemedicine during the COVID-19 pandemic has led to areas of concern for rheumatology trainees including inadequate supervision and clinical teaching. Our results suggest a need for education on evaluation of new patients using telemedicine, increasing telemedicine training, and ensuring adequate supervisory arrangements.Table 1.Telemedicine use, supervision, and training by region.

Abstract
Abstract
Introduction
All patients presenting to emergency departments (EDs) with traumatic injuries require tetanus immunity assessments. Inaccurate tetanus vaccination history based on patient recall incurs unnecessary costs on the NHS. Point-of-care immunochromatographic tests (Tetanus Quick Sticks [TQS]) quickly identify tetanus immunity status. We aim to evaluate the diagnostic accuracy and cost-efficacy of TQS to assess their relevance in emergency care.
Method
The systematic review followed PRISMA guidelines. A retrospective search of MEDLINE, Embase, Global Health, HMIC and The Cochrane Library was conducted. Studies were eligible if sensitivity, specificity, or cost-efficacy of TQS were reported. At least two authors independently analysed the data from each study.
Results
12 studies were suitable for inclusion (n = 1,662,865 participants): one retrospective and 11 prospective observational cohort studies. Eight studies assessed diagnostic accuracy with the median sensitivity at 86% (55-100) and the median specificity at 97.5% (1-100). All six studies investigating cost-efficacy reported greater savings when using TQS instead of using vaccination history, due to a decrease in unnecessary tetanus vaccine and immunoglobulin administration.
Conclusions
TQS is a safe diagnostic tool, especially when used by trained operators. TQS widely reduces costs in comparison to traditional vaccination history. We recommend the use of TQS in Emergency Departments throughout the NHS.

Abstract
BACKGROUND Nasal trauma is the most common facial injury worldwide. Prompt assessment allows for recognition of injuries requiring surgical intervention in the form of nasal bone manipulation. The literature is unclear to what extent patients undergoing conservative management subsequently require surgical intervention. METHODS A retrospective chart review of all patients presenting with nasal injury between July 2017 and July 2018 who underwent conservative and surgical management was undertaken. Re-referral and subsequent surgical intervention were documented. RESULTS In a cohort of 390 patients with nasal injury 229 patients underwent conservative management. Average age was 29 years. Males comprised 60% of our conservative cohort and 81% of the manipulated cohort. 8.3% of patients managed conservatively and 12% of those undergoing manipulation were re-referred. CONCLUSION Nasal trauma assessment is a significant workload for an ENT unit. Conservative management is appropriate following clinical assessment and does not lead to increased intervention compared with those who are surgically manipulated.

Studies on the effectiveness of seasonal influenza vaccine can affect an individual's perception of the ability of this vaccine to protect against influenza. However, vaccine effectiveness studies are designed to inform public health decisions rather than for individual decision-making. This overview explains what vaccine effectiveness means and why vaccine effectiveness estimates can vary. Individual variation in the response to seasonal influenza vaccine is based upon risk factors such as age, underlying health conditions, immune status and risk of infection and complications. Therefore, an individual's decision to get vaccinated should be primarily informed by their risk of influenza illness and their risk of transmitting influenza to vulnerable people.

Abstract
Current decision support interventions for airway management in anaesthesia lack the application of Human Factors Engineering; leading to interventions that can be disruptive, inefficient and error-inducing. This study followed a decision-centred design process to identify decision support that can assist anaesthesia teams with challenging airway management situations. Field observations, Critical Decision Method interviews and focus groups were conducted to identify the most difficult decisions and their requirements. Data triangulation narrowed the focus to key decisions related to preparation and planning, and the transitioning between airway techniques during difficulties. Five decision-support interventions were identified and positively rated by anaesthesia team members in relation to their perceived effectiveness. An organized airway equipment trolley was chosen as the most beneficial decision support intervention. This study reiterated the key importance of both Human Factors Engineering and data triangulation when designing for healthcare.

Abstract
AIMS To assess current national practice in the management of severe open tibial fractures against national standards, using data collected by the Trauma and Audit Research Network. MATERIALS AND METHODS Demographic, injury-specific, and outcome data were obtained for all grade IIIB/C fractures admitted to Major Trauma Centres in England from October 2014 to January 2016. RESULTS Data was available for 646 patients with recorded grade IIIB/C fractures. The male to female ratio was 2.3:1, mean age 47 years. 77% received antibiotics within 3 h of admission, 82% were debrided within 24 h. Soft tissue coverage was achieved within 72 h of admission in 71%. The amputation rate was 8.7%. 4.3% of patients required further theatre visits for infection during the index admission. The timing of antibiotics and surgery could not be correlated with returns to theatre for early infection. There were significant differences in the management and outcomes of patients aged 65 and over, with an increase in mortality and amputation rates. CONCLUSIONS Good outcomes are reported from the management of IIIB/C fractures in Major Trauma Centres in England. Overall compliance with national standards is particularly poor in the elderly. Compliance did not appear to affect rates of returning to theatre or early infection. Appropriately applied patient reported outcome measures are needed to enhance the evidence-base for management of these injuries.

Abstract
This controlled trial used a prospective, randomised open design to compare the effectiveness of acupuncture and intra-articular injections in reducing chronic pain associated with osteoarthritis of the hip. Thirty two patients awaiting hip arthroplasty with chronic pain of more than twelve months duration were included. Group A received acupuncture using a standardised technique of periosteal needling to the greater trochanter of the femur with three acupuncture needles. The treatment was repeated on three occasions at weekly intervals. Group B received an intra-articular/peri-articular hip injection of 20ml of 1% lignocaine + 80mg Depo-Medrone. Patients were assessed for pain intensity, mobility and pattern of analgesia usage pre-treatment and at one, two and four week intervals thereafter. Both groups experienced a decrease in pain intensity and analgesic usage following treatment. This decrease was greater in the acupuncture group. However, mobility remained unchanged in both groups. From the results of this study, periosteal acupuncture appears to be as effective as an intra-articular injection in relieving the pain associated with osteoarthritis of the hip. However, due to the small numbers involved, statistical significance was not achieved.

Abstract
Morbidity associated with femur fractures in polytrauma patients is known to be high. The many unsolved clinical questions include the immunological effect of the fracture and its fixation, timing of fracture fixation, management of fracture non-union, effect of infection and critical size of bone defects. The aim of this study was to establish a clinically-relevant and reproducible animal model with regards to histological, biomechanical and radiological changes during bone healing. A custom-designed intramedullary nail with interlocking system (RabbitNail, RISystem AG, Davos Platz, Switzerland) was used for fixation, following femur fracture. New Zealand White rabbits were assigned to two groups: 1. closed fracture model (CF; non-survival model: n = 6, survival model: n = 3) with unilateral mid-shaft femur fracture created by blunt force; 2. osteotomy model (OT; survival model: n = 14) with unilateral transverse osteotomy creating femur fracture. There were no intraoperative complications and full-weight bearing was achieved in all survival rabbits. Significant periosteal reaction and callus formation were confirmed from 2 weeks postoperatively, with a significant volume formation (739.59 ± 62.14 mm3) at 8 weeks confirmed by micro-computed tomography (µ-CT). 2 months after fixation, there was no difference between the osteotomised and contralateral control femora in respect to the maximum torque (3.47 ± 0.35 N m vs. 3.26 ± 0.37 N m) and total energy (21.11 ± 3.09 N m × degree vs. 20.89 ± 2.63 N m × degree) required to break the femur. The data confirmed that a standardised internal fixation technique with an intramedullary nail for closed fracture or osteotomy produced satisfactory bone healing. It was concluded that important clinically-relevant studies can be conducted using this rabbit model.

Abstract
With effective antiviral therapies, rates of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) and decompensated liver disease requiring liver transplantation (LT) are expected to decrease. We aim to evaluate overall trends in LT waitlist registrations, waitlist survival and likelihood of receiving LT among chronic HBV patients in the United States. Using the United Network for Organ Sharing database, we retrospectively evaluated adults (age≥18) with chronic HBV (with and without HCC) listed for LT from 1992 to 1996 (Era 1) vs 1997 to 2004 (Era 2) vs 2005-2015 (Era 3). Multivariate Cox-regression models evaluated probability of waitlist survival and receiving LT. Overall, 6797 chronic HBV adults were listed for LT. While the total number of HBV patients listed for LT remained stable, the proportion of HBV patients with HCC increased from 5.4% in Era 1 to 39.0% in Era 3. Compared to Era 1, waitlist mortality was higher in Era 2 (HR: 4.55, P<.001) and Era 3 (HR: 3.63, P<.001). However, in the most recent era, waitlist mortality significantly improved (compared to 2005-2007: 2008-2011: HR: 0.74, P=.05, 95% CI: 0.55-0.99; 2012-2015: HR: 0.53, P<.001, 95% CI: 0.38-0.75). Probability of receiving LT was also lower with latter time periods (compared to 2005-2007: 2008-2011: HR: 0.77, P<.001 95% CI: 0.68-0.86; 2012-2015: HR: 0.61, P<.001, 95% CI: 0.54-0.69). Although the number of HBV patients requiring LT remained stable, the proportion of HBV patients with HCC continues to rise. The decrease in waitlist mortality and lower likelihood of LT among HBV patients may reflect the effectiveness of antiviral therapies in delaying disease progression in the current era.

Abstract
Inclusion of compatible living donor and recipient pairs (CPs) in kidney paired donation (KPD) programs could increase living donor transplantation. We introduce the concept of a reciprocity-based strategy in which the recipient of a CP who participates in KPD receives priority for a repeat deceased donor transplant in the event their primary living donor KPD transplant fails, and then we review the practical and ethical considerations of this strategy. The strategy limits prioritization to CPs already committed to living donation, minimizing the risk of unduly influencing donor behavior. The provision of a tangible benefit independent of the CP's actual KPD match avoids many of the practical and ethical challenges with strategies that rely on finding the CP recipient a better-matched kidney that might provide the CP recipient a future benefit to increase KPD participation. Specifically, the strategy avoids the potential to misrepresent the degree of future benefit of a better-matched kidney to the CP recipient and minimizes delays in transplantation related to finding a better-matched kidney. Preliminary estimates suggest the strategy has significant potential to increase the number of living donor transplants. Further evaluation of the acceptance of this strategy by CPs and by waitlisted patients is warranted.
