Abstract
BACKGROUND Globally, there are about 800 maternal deaths every day, with low-to-middle-income countries accounting for most of these deaths. A lack of access to maternal healthcare services is one of the main causes of these deaths. In sub-Saharan Africa (SSA), one of the barriers to accessing maternal healthcare services by women is a lack of their male partners' involvement. This scoping review aimed to assess the enablers and barriers to men's involvement in maternal healthcare services. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) checklist was used as a guide for this review. We searched for peer-reviewed articles published between 2013 and 2023 in the English language from SCOPUS, ScienceDirect, PubMed, Africa Journals Online (AJOL), and Google Scholar databases. Two reviewers independently conducted the data extraction and article selection. All of the authors discussed and decided on the codes and categories for enablers and barriers after using NVivo to generate them. RESULTS Twenty-seven articles were used in this review. Of these, seventeen were qualitative studies, six were quantitative studies, and four were mixed-methods studies. The enablers of men's involvement in maternal healthcare were grouped into sociodemographic factors, health system factors, and policy factors, while barriers were grouped into sociodemographic, cultural, economic, and health system barriers. The lack of maternal health knowledge, insufficient economic resources, and unfriendly staff at healthcare facilities all contributed to a lack of involvement by men. CONCLUSION To improve men's involvement in maternal healthcare in SSA, there should be economic empowerment of both men and women, health education, and the provision of adequate infrastructure in healthcare facilities to accommodate men.

Abstract
INTRODUCTION Vertigo is a prevalent and burdensome symptom. More than 80% of patients with vertigo are primarily treated by their general practitioner (GP) and are never referred to a medical specialist. Despite this therapeutic responsibility, the GP's diagnostic toolkit has serious limitations. All recommended tests lack empirical evidence, because a diagnostic accuracy study on vestibular disorders ('How well does test x discriminate between patients with or without target condition y?') has never been performed in general practice. The VERtigo DIagnosis study aims to fill this gap. METHODS AND ANALYSIS We will perform a diagnostic accuracy study on vertigo of primary vestibular origin in general practice to assess the discriminative ability of history taking and physical examination. We will compare all index tests with a respective reference standard. We will focus on five target conditions that account for more than 95% of vertigo diagnoses in general practice: (1) benign paroxysmal positional vertigo, (2) vestibular neuritis, (3) Ménière's disease, (4) vestibular migraine (VM) and (5) central causes other than VM. As these five target conditions have a different pathophysiology and lack one generally accepted gold standard, we will use consensus diagnosis as a construct reference standard. Data for each patient, including history, physical examination and additional tests as recommended by experts in an international Delphi procedure, will be recorded on a standardised form and independently reviewed by a neurologist and otorhinolaryngologist. For each patient, the reviewers have to decide about the presence/absence of each target condition. We will calculate sensitivity, specificity, predictive values, likelihood ratios and diagnostic ORs, followed by decision rules for each target condition. ETHICS AND DISSEMINATION The study obtained approval from the Vrije Universiteit Medical Center Medical Ethical Review Committee (reference: 2022.0817-NL83111.029.22). We will publish our findings in peer-reviewed international journals. TRIAL REGISTRATION NUMBER ISRCTN97250704.

Abstract
BACKGROUND The combination of rectally administered indomethacin and placement of a prophylactic pancreatic stent is recommended to prevent pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) in high-risk patients. Preliminary evidence suggests that the use of indomethacin might eliminate or substantially reduce the need for stent placement, a technically complex, costly, and potentially harmful intervention. METHODS In this randomised, non-inferiority trial conducted at 20 referral centres in the USA and Canada, patients (aged ≥18 years) at high risk for post-ERCP pancreatitis were randomly assigned (1:1) to receive rectal indomethacin alone or the combination of indomethacin plus a prophylactic pancreatic stent. Patients, treating clinicians, and outcomes assessors were masked to study group assignment. The primary outcome was post-ERCP pancreatitis. To declare non-inferiority, the upper bound of the two-sided 95% CI for the difference in post-ERCP pancreatitis (indomethacin alone minus indomethacin plus stent) would have to be less than 5% (non-inferiority margin) in both the intention-to-treat and per-protocol populations. This trial is registered with ClinicalTrials.gov (NCT02476279), and is complete. FINDINGS Between Sept 17, 2015, and Jan 25, 2023, a total of 1950 patients were randomly assigned. Post-ERCP pancreatitis occurred in 145 (14·9%) of 975 patients in the indomethacin alone group and in 110 (11·3%) of 975 in the indomethacin plus stent group (risk difference 3·6%; 95% CI 0·6-6·6; p=0·18 for non-inferiority). A post-hoc intention-to-treat analysis of the risk difference between groups showed that indomethacin alone was inferior to the combination of indomethacin plus prophylactic stent (p=0·011). The relative benefit of stent placement was generally consistent across study subgroups but appeared more prominent among patients at highest risk for pancreatitis. Safety outcomes (serious adverse events, intensive care unit admission, and hospital length of stay) did not differ between groups. INTERPRETATION For preventing post-ERCP pancreatitis in high-risk patients, a strategy of indomethacin alone was not as effective as a strategy of indomethacin plus prophylactic pancreatic stent placement. These results support prophylactic pancreatic stent placement in addition to rectal indomethacin administration in high-risk patients, in accordance with clinical practice guidelines.

Abstract
INTRODUCTION South Africa has an inequitable distribution of health workers between the public and private sector, with rural areas being historically underserved. As rural background of health workers has been advocated as the strongest predictor of rural practice, the Umthombo Youth Development Foundation (UYDF) has invested in recruiting and training rural-origin health science students since 1999 as a way of addressing staff shortages at 15 district hospitals in northern KwaZulu-Natal Province, South Africa. UYDF's intervention is to support students to overcome their academic, social, and economic challenges and expose them annually to rural health practice. This study investigated the effects of various retention factors on the choice of where rural-origin UYDF graduates worked, namely in rural or urban, public or private settings. METHODS An online survey was developed containing questions relevant to the retention of health workers and included: personal satisfaction; hospital resources and employment factors; professional development and support; and community integration, as well as the reasons for working where they do. Of the 317 eligible health science graduates invited to participate, 139 (44%) responded. Descriptive statistics were compiled. RESULTS Forty-nine percent of graduates were working at a rural public healthcare facility (PHCF), followed by 34% at an urban PHCF, and 11% in the private sector. All the respondents, wherever they worked, reported positively on their work, management support, colleagues, and ability to practise their skills. Graduates working at rural PHCFs reported that patient care was sometimes compromised due to lack of equipment or medicines, with staff shortages being greater than at urban PHCFs. All the graduates reported that they had insufficient time to interact with peers regarding difficult cases, while those at rural PHCFs lacked access to senior staff or specialists compared to those working at urban PHCFs or urban private practice. Lack of professional development opportunities was reported by graduates at rural PHCFs as a reason they may leave, while those at urban PHCFs cited the intention to specialise. Graduates no longer working at a rural hospital reported that the lack of funded posts at rural PHCFs was the main reason (39%), followed by the desire to specialise (29.6%). Graduates working at rural PHCFs cited the 'ability to serve their community' and being 'close to family and friends' as the main reason for working where they do, whereas those working at urban PHCFs cited 'good work experience'. CONCLUSION While nearly half of the rural-origin UYDF graduates surveyed continue to work in rural areas, this is considerably less than previously reported, indicating that rural-origin health workers are affected by retention factors. The lack of funded posts at rural PHCFs is a major barrier to the employment and retention of health workers, and to addressing the unequal distribution of health workers between urban and rural PHCFs. This requires commitment from government and other role players to increase the attraction and retention of health workers in rural areas. Focusing on the recruitment of rural students to become health workers, in the absence of adequate retention policies, is insufficient to adequately address shortages of staff at rural PHCFs, as rural-origin graduates will move from rural PHCFs to facilities where they can access these benefits.

Abstract
Introduction: HIV-testing services (HTS) are an important point of entry to prevention and treatment of HIV in South Africa. Despite the availability of HTS across the region and in SA, the uptake among men remains low, especially young men residing in rural and peri-urban communities. This study aimed to explore interventions that could improve the uptake of HTS among young men in KwaZulu-Natal.Methods: A descriptive exploratory qualitative study was conducted in which 17 young men and two health care providers in Ladysmith were purposively and conveniently sampled. Data were collected through semi-structured interviews using WhatsApp and landline audio calls between September and December 2021 and thematically analysed.Results: An improvement in the health care provider attitudes and service delivery, establishment of adherence clubs for young people living with HIV, ensuring a diverse and balanced health care provider staff composition at primary health care facilities, and increased demand creation in spaces frequented by men are vital for enhancing access and utilisation of HTS among young men. Additionally, health care providers believe that the presence of male health care providers, investment in health education, prioritising men in the morning at the primary health care facilities, and the establishment of male clinics within communities as key factors in improving the uptake of HTS among young men.Conclusion: To attract and retain young men in HTS and in HIV treatment and care, several improvements at primary health care facilities need to be implemented. These should focus on addressing the specific needs and preferences of young men, ensuring their comfort and engagement in health care.

Abstract
Spintronic nano-synapses and nano-neurons perform neural network operations with high accuracy thanks to their rich, reproducible and controllable magnetization dynamics. These dynamical nanodevices could transform artificial intelligence hardware, provided they implement state-of-the-art deep neural networks. However, there is today no scalable way to connect them in multilayers. Here we show that the flagship nano-components of spintronics, magnetic tunnel junctions, can be connected into multilayer neural networks where they implement both synapses and neurons thanks to their magnetization dynamics, and communicate by processing, transmitting and receiving radiofrequency signals. We build a hardware spintronic neural network composed of nine magnetic tunnel junctions connected in two layers, and show that it natively classifies nonlinearly separable radiofrequency inputs with an accuracy of 97.7%. Using physical simulations, we demonstrate that a large network of nanoscale junctions can achieve state-of-the-art identification of drones from their radiofrequency transmissions, without digitization and consuming only a few milliwatts, which constitutes a gain of several orders of magnitude in power consumption compared to currently used techniques. This study lays the foundation for deep, dynamical, spintronic neural networks.

Abstract
PURPOSE/OBJECTIVE(S) Radiation (RT)-induced lymphopenia (RIL) occurs in up to 75% of patients undergoing RT and is associated with worse tumor control and survival across a spectrum of solid tumors. Patients undergoing hypofractionated RT are at lower risk of RIL compared with patients treated with more prolonged RT courses. However, it is unknown whether immune repertoire diversity is similarly affected by fractionation scheme in patients undergoing RT. This prospective study analyzed RT-induced changes in immune repertoire diversity in patients treated with conventionally (CFRT) vs hypofractionated RT (HFRT). MATERIALS/METHODS RNA-based T and B cell receptor sequencing was performed on peripheral lymphocytes collected prospectively before RT and within 4 weeks of the last RT fraction from 23 patients (18 men, 5 women, median age 67 y) with primary solid tumors undergoing CFRT (≤3 Gy/day x ≥10 days, n = 13) or HFRT (≥5 Gy/day x ≤5 days, n = 10). Absolute lymphocyte counts (ALC; cells/μL) were obtained from clinical laboratory data. The number of unique CDR3 receptors (uCDR3) and Shannon entropy were used to monitor changes in T (TCR Vβ) and B (BCR IgH) receptor diversity. RESULTS ALC decreased after RT in 90% (20/22) of patients (mean pre-RT ALC 1830 vs 1040 post-RT, p <0.001). Mean % ALC loss was greater in CFRT vs HFRT patients (44.3 vs. 35.2%). After RT, entropy in IgH and Vβ decreased in 18/23 (78%) and 17/23 (74%) patients, respectively; uCDR3 in IgH and Vβ decreased in 14/23 (61%) and 15/23 (65%). Among patients with concordant decreases in ALC and uCDR3, a moderate correlation between magnitude of ALC loss and uCDR3 levels in the T-cell receptor Vβ was observed (r = 0.64, p = 0.02). For both receptor species studied (IgH and Vβ), HFRT patients were more likely to have an increase in either entropy or uCDR3 in the face of decreased ALC (36 vs 15%, X2 p = 0.03). Furthermore, while decreases in entropy were observed among the CFRT patients for both IgH (median entropy 10.4 vs 9.4, p = 0.06) and Vβ (9.7 vs 8.1, p = 0.02), entropy did not significantly change following RT in the HFRT patients (IgH 10.6 vs 10.4, p = 0.74 and Vβ 10.9 vs 10.8, p = 0.24). CONCLUSION RT-induced changes in immune repertoire diversity are variably reflected in the peripheral ALC. Both HFRT and CFRT depleted circulating lymphocytes, but patients undergoing HFRT were more likely to experience increases in T and B cell diversity metrics despite lymphopenia. It is therefore possible that relative sparing of repertoire diversity among patients undergoing HFRT could increase the likelihood of tumor antigen recognition by peripheral blood lymphocytes. As immune repertoire diversity is associated with the likelihood of response to immunotherapy, these findings also have implications for RT-immunotherapy combinations. Further study is required to understand the relationship between RT exposure to circulating lymphocyte populations and immune repertoire diversity.

Abstract
Microalgae represent a promising source of triglycerides and free fatty acids, synthesized in the form of lipids, for use in renewable fuels and chemicals. One challenge is the ability to efficiently recover the lipids from within the microalgae cell. Although various techniques have been studied individually, a comprehensive study of extraction techniques using consistent experimental and analytical methodology is missing. This study aims to provide this unifying comparison using the common microalgae strain Chlorella vulgaris. The factors that were surveyed and then optimized to achieve maximum extraction efficiency included the solvent type; mechanical pre-treatment using a ball mill at a variety of grinding speeds; microalgae-to-solvent ratio; extraction facilitated by microwave; extraction facilitated by sonication; extraction facilitated using increased temperature; and extraction facilitated by in situ transesterification to convert the lipids into esters prior to extraction. The optimum conditions determined during these studies were utilizing methanol as the solvent, with ball mill pretreatment at a grinding speed of 500 rpm, and a 1:9 microalgae to solvent ratio. When used in combination with microwave-assisted extraction at a temperature of 140 °C, approximately 24 wt% of the initial lipids were recovered. Recoveries of over 70 wt% were obtained without a microwave at extraction temperatures of over 200 °C.

Abstract
BACKGROUND AND AIMS Palliation of malignant gastric outlet obstruction (mGOO) allows resumption of peroral intake. Although surgical gastrojejunostomy (SGJ) provides durable relief, it may be associated with a higher morbidity, interfere with chemotherapy, and require an optimum nutritional status. EUS-guided gastroenterostomy (EUS-GE) has emerged as a minimally invasive alternative. We aimed to conduct the largest comparative series to date between EUS-GE and SGJ for mGOO. METHODS This multicenter retrospective study included consecutive patients undergoing SGJ or EUS-GE at 6 centers. Primary outcomes included time to resumption of oral intake, length of stay (LOS), and mortality. Secondary outcomes included technical and clinical success, reintervention rates, adverse events (AEs), and resumption of chemotherapy. RESULTS A total of 310 patients were included (EUS-GE, n = 187; SGJ, n = 123). EUS-GE exhibited significantly lower time to resumption of oral intake (1.40 vs 4.06 days, P < .001), at lower albumin levels (2.95 vs 3.33 g/dL, P < .001), and a shorter LOS (5.31 vs 8.54 days, P < .001) compared with SGJ; there was no difference in mortality (48.1% vs 50.4%, P = .78). Technical (97.9% and 100%) and clinical (94.1% vs 94.3%) success was similar in the EUS-GE and SGJ groups, respectively. EUS-GE had lower rates of AEs (13.4% vs 33.3%, P < .001) but higher reintervention rates (15.5% vs 1.63%, P < .001). EUS-GE patients exhibited significantly lower interval time to resumption of chemotherapy (16.6 vs 37.8 days, P < .001). Outcomes between the EUS-GE and laparoscopic (n = 46) surgical approach showed that EUS-GE had shorter interval time to initiation/resumption of oral intake (3.49 vs 1.46 days, P < .001), decreased LOS (9 vs 5.31 days, P < .001), and a lower rate of AEs (11.9% vs 17.9%, P = .003). CONCLUSIONS This is the largest study to date showing that EUS-GE can be performed among nutritionally deficient patients without affecting the technical and clinical success compared with SGJ. EUS-GE is associated with fewer AEs while allowing earlier resumption of diet and chemotherapy.

Abstract
BACKGROUND The youth is at a heightened risk of immunodeficiency virus and/or acquired immunodeficiency syndrome (HIV and/or AIDS) infection because of risk-taking behaviour. There remains a gap in understanding young men's knowledge of HIV and/or AIDS and HIV testing services (HTS) in hard-to-reach communities in South Africa. AIM This article aimed to explore young men's knowledge of HIV and/or AIDS, including HTS in Ladysmith, KwaZulu-Natal (KZN). SETTING Rural and peri-urban areas around the town of Ladysmith. METHODS Employing a qualitative descriptive research design, 17 young men aged between 18 and 30 years were purposively and conveniently sampled and interviewed using WhatsApp and landline audio calls to collect their data, which was thematically analysed. RESULTS Young men had good knowledge of HIV and/or AIDS but lacked knowledge about HTS and HIV self-testing (HIVST). They obtained their information about HIV and/or AIDS and HTS from various sources and were aware of where to access HTS. They were generally unaware and supportive of HIVST. CONCLUSION Male-targeted HIV and/or AIDS knowledge and testing interventions are needed to encourage and support young men to test for HIV. Human immunodeficiency virus self-testing should be explored as an alternative to clinic-based service to encourage young men to know their status, specifically those with limited access to or are reluctant to attend clinics. Strengthening HIV and/or AIDS education could facilitate better decision-making towards HIV testing among young men.Contribution: This study contributes to an understanding of young adult men's knowledge of HIV and/or AIDS and HTS in underserved settings in South Africa.

Abstract
BACKGROUND Necrotizing pancreatitis can be complicated by Necrotic Fluid Collections (NFC). Guidelines recommend waiting for 4 weeks from the onset of acute pancreatitis (AP) before considering endoscopic drainage. We aimed to compare outcomes and safety in patients undergoing early versus late drainage of NFC. METHODS We performed a retrospective review of all patients who underwent Dual Modality Drainage (DMD) [combined endoscopic and percutaneous drainage] for NFC from January 2007 to December 2020. Patients were stratified into the "early" group (DMD < 28 days from AP onset) and were matched to "late" (DMD ≥ 28 days) drainage group using propensity- core-matching. Primary outcomes of interest were technical success and adverse events. Secondary outcomes included clinical success, late complication rates, and mortality. RESULTS We identified 278 patients who underwent DMD for NFC. Thirty-nine belonged to the early group and were matched to 174 patients from the late group. Technical success was similar in both early and late groups (97.4% vs 99.4%: P = 0.244) as were the procedural and early post-procedural (< 14 days) adverse events rates (23.1% vs 27.6%: P = 0.565). Clinical success (92.3% vs 93.1%; P = 0.861) and late complication rates (23.1% vs 31.6%; P = 0.294) were similar. There were 2 deaths (5.7%) in the early vs. 9 (5.2%) in the late group, P = 0.991. CONCLUSIONS When performed in a tertiary care center with expertise in therapeutic endoscopic ultrasound, early drainage of NFC appears to be feasible and safe. Further studies are needed to validate our results.

Abstract
BACKGROUND Continuing professional development (CPD) is a key aspect to fulfil a commitment to lifelong learning for professionals registered with the Medical and Dental Council, the intention being to promote the health of patients and develop clinical expertise. The absence of formal CPD requirements for practitioners in Eswatini has resulted in a move to introduce an accredited system. METHODS The qualitative study followed a participatory action research (PAR) methodology using a cooperative inquiry group of 10 medical practitioners in Eswatini to investigate how the current CPD program could be improved and formalised. PAR entailed four stages; observation, reflection, planning and action, using a semi-structured format to explore the areas of concern. RESULTS Reflecting on the current situation resulted in three ways to improve CPD being identified: (1) adopt a formal, compulsory CPD model; (2) recognise achievements by practitioners who endeavour to improve their skills/knowledge through Entrustable Professional Activities, and (3) ensure that CPD is relevant to the workplace by using Quality-Improvement CPD (QI-CPD) and reflective diaries. These would be done by involving local practitioners, using adult learning principles and ensuring continuous evaluation and improvement of the CPD model. CONCLUSIONS There was general agreement on the need for a formalised CPD system to improve skill levels and provide an open platform to enhance patient care in a resource constrained setting. The findings provided information that can be used to plan and action its implementation through engagement with the country's doctors in various forums and through ongoing research.

Abstract
Multi-trait genomic selection (MT-GS) has the potential to improve predictive ability by maximizing the use of information across related genotypes and genetically correlated traits. In this study, we extended the use of sparse phenotyping method into the MT-GS framework by split testing of entries to maximize borrowing of information across genotypes and predict missing phenotypes for targeted traits without additional phenotyping expenditure. Using 300 advanced breeding lines from North Dakota State University (NDSU) pulse breeding program and ∼200 USDA accessions that were evaluated for 10 nutritional traits, our results show that the proposed sparse phenotyping aided MT-GS can further improve predictive ability by >12% across traits compared with univariate (UNI) genomic selection. The proposed strategy departed from the previous reports that weak genetic correlation is a limitation to the advantage of MT-GS over UNI genomic selection, which was evident in the partially balanced phenotyping-enabled MT-GS. Our results point to heritability and genetic correlation between traits as possible metrics to optimize and further improve the estimation of model parameters, and ultimately, prediction performance. Overall, our study offers a new approach to optimize the prediction performance using the MT-GS and further highlight strategy to maximize the efficiency of GS in a plant breeding program. The sparse-testing-aided MT-GS proposed in this study can be further extended to multi-environment, multi-trait GS to improve prediction performance and further reduce the cost of phenotyping and time-consuming data collection process.

Abstract
In antiferromagnets, the efficient transport of spin-waves has until now only been observed in the insulating antiferromagnet hematite, where circularly (or a superposition of pairs of linearly) polarized spin-waves diffuse over long distances. Here, we report long-distance spin-transport in the antiferromagnetic orthoferrite YFeO3, where a different transport mechanism is enabled by the combined presence of the Dzyaloshinskii-Moriya interaction and externally applied fields. The magnon decay length is shown to exceed hundreds of nanometers, in line with resonance measurements that highlight the low magnetic damping. We observe a strong anisotropy in the magnon decay lengths that we can attribute to the role of the magnon group velocity in the transport of spin-waves in antiferromagnets. This unique mode of transport identified in YFeO3 opens up the possibility of a large and technologically relevant class of materials, i.e., canted antiferromagnets, for long-distance spin transport.

Abstract
INTRODUCTION Epistaxis is a common otolaryngologic problem that affects most of the general population. Common risk factors for epistaxis include nasal irritants, nasal/facial oxygen use, certain systemic conditions (e.g., hypertension and coagulopathies) and medication use (e.g., anticoagulants and intranasal medications). This study examined risk factors for and management of epistaxis in patients admitted for other medical conditions who developed an episode of epistaxis during their hospital admission. METHODS Patients were included in the study if they were older than 18, admitted for medical illnesses other than epistaxis and developed an episode of epistaxis during their admission during calendar year 2020 at the authors' institution's hospitals. Electronic health record data regarding sociodemographic characteristics, common risk factors (e.g. oxygen use, anticoagulant use, history of hypertension) and treatment for epistaxis (e.g. holding anticoagulation therapy, administration of oxymetazoline, nasal cautery, nasal packing) were extracted from each chart. Patients were split into otolaryngologic treatment versus no treatment groups and risk factors were compared between sample subgroups. RESULTS A total of 143 sample patients were included, with most common reason for admission being cardiovascular related, 48 (33.6%). Most patients, 104 (72.7%), did not have a previous diagnosis of epistaxis, were positive for anticoagulant use, 106 (74.1%) and were positive for hypertension, 95 (66.4%). Oxygen use showed a significantly decreased risk for intervention (OR 0.45, 95% CI: 0.23-0.894; p = 0.028). Most patients required changes in medical management (e.g., holding anticoagulation or starting nasal saline sprays/emollients). CONCLUSION These results demonstrate the common risk factors for epistaxis in patients admitted for other clinical diseases. Identifying at-risk patients for epistaxis at hospital admission can help to initiate measures to prevent epistaxis episodes. Future studies are needed to study epistaxis risk factors and identify effective preventative measures for epistaxis among hospital populations.

Abstract
Background/Aims Transoral incisionless fundoplication (TIF) is an accepted anatomic treatment for gastroesophageal reflux disease in selected patients. In this report, we analyze our institution’s programmatic allocation of resources during the safe implementation of TIF as a new procedure.
Methods A retrospective analysis of all patients who underwent TIF from January 2020 to February 2021 at our institution was performed. The process of initially allocating the operating room (OR) with overnight admission and postoperative esophagram for added safety, and subsequently transitioning TIF to the endoscopy suite (ES) as an outpatient procedure was described. Patient safety and outcomes were evaluated during transition.
Results Thirty patients who underwent TIF were identified. The mean age was 51.2±16.0 years. TIF was performed in an OR in nine patients (30%) and 21 (70%) in the ES. All the OR patients were admitted overnight and had routine esophagogram. In contrast, four (19%) from the ES group required clinically-indicated admission and three (14.2%) required esophagram. The mean procedure duration was significantly lower in the ES group (65.7 min vs. 84 min, p=0.02).
Conclusions A stepwise, resource-efficient process was described that allowed safe initiation of TIF as a new technique and its effective transition to a fully outpatient procedure.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
Up‐to‐date information on coronavirus disease 2019 (COVID‐19) outcomes and risk factors in haematopoietic cell transplantation (HCT) recipients is required to inform on decisions about cancer treatment and COVID‐19 mitigation strategies. We performed a meta‐analysis to address this knowledge gap. All studies with at least five patients who reported COVID‐19‐related deaths in HCT recipients were included. The primary outcome was COVID‐19‐related death. Secondary outcomes were COVID‐19‐related mechanical ventilation (MV) and intensive care unit (ITU) admission. The cumulative COVID‐19‐related death rate among HCT recipients was 21% (95% confidence interval [CI] 18%–24%), while MV and ITU admission rates were 14% (95% CI 11%–17%) and 18% (95% CI 14%–22%), respectively. Subgroup analysis showed higher death rates in patients who developed COVID‐19 within 12 months of HCT (risk ratio [RR] 1.82, 95% CI 1.09–3.03), within 6 months of receiving immunosuppressant drugs (RR 2.11, 95% CI 1.38–3.20) or in the context of active graft‐versus‐host disease (RR 2.38, 95% CI 1.10–5.16). Our findings support the idea that HCT should remain an integral part of cancer treatment during the COVID‐19 pandemic but also highlight the need to prioritise preventative measures in those patients who are at increased risk of adverse COVID‐19 outcomes.

Abstract
Black adolescents in the United States have experienced an increase in suicidal thoughts and behaviors (STBs). Since Black adolescents are overrepresented in the youth punishment system, more research is needed to investigate correlates of STBs for this population. The purpose of this paper is to explore and establish correlates of individual, family, and community risk and protective factors and their relationship to lifetime STBs in a national sample of Black youth with arrest histories. Guided by an intersectional eco-behavioral lens, we investigated individual, family and contextual risk and protective factors for STBs among a national sample of justice-involved Black youth aged 12-17 with a history of arrest (n = 513). We used logistic regression models to test risk and protective factors for STBs. Among the sample, 9.78% endorsed suicidal ideation, and 7.17% endorsed a previous suicide attempt. Further, gender (female) and depression severity were risk factors for STBs, while positive parenting and religiosity were protective factors for STBs. School engagement was associated with lower levels of suicidal ideation. The findings suggest suicide prevention and intervention efforts should identify developmentally salient risk and protective factors to reduce mental health burden associated with STBs and concurrent alleged law-breaking activity of Black youth.

Abstract
Purpose
Among the existing buildings, hotels use as much as 50% of their total expenses on energy and offer significant opportunities for energy efficiency improvement. Yet, comparatively the level of implementation of energy retrofits (ER) in hotels appear to be low. This has been mainly attributed, inter alia, to the absence of clearly defined process for ensuring the delivery of ER and lack of proactive guidance for project teams to make right decisions. Hence, this study aims to propose an effective decision-making process, which could support the successful adoption and implementation of in-house-led ER projects in existing hotel buildings.
Design/methodology/approach
Two in-depth case studies were carried out focussing on ER projects led by in-house teams in existing hotel buildings. Data was collected via 14 semi-structured interviews and was analysed through code-based content analysis.
Findings
The decision-making process for ER projects led by in-house teams was developed, which presents 39 key activities to be performed and 16 key decisions to be made. The parties responsible for these identified actions and decisions as well as the points at which each decision should be made to ensure the success of ER projects was also identified.
Originality/value
A total of 21 new activities and 10 decisions relevant for in-house team led ER decision-making processes previously not found in literature were identified. It is hoped that the decision-making process developed in this study will serve as a roadmap for the effective adoption and implementation of ER in existing hotel buildings.

Abstract
BACKGROUND Endoscopic therapy with endoscopic retrograde cholangiopancreatography is considered the first-line treatment in the management of post-cholecystectomy bile leak (PCBL). Currently, there is no consensus on the most effective endoscopic intervention for PCBL. Hence, we performed a systematic review and meta-analysis to compare the effectiveness and safety of the two interventional groups (biliary sphincterotomy [BS] alone vs. biliary stent ± BS) in management of PCBL. METHODS We conducted a comprehensive search of multiple electronic databases and conference proceedings (from inception through January 2021). The primary outcome was to compare the pooled rate of clinical success between the 2 groups. The secondary outcome was to estimate the pooled rate of adverse events. RESULTS The pooled rate of clinical success with BS alone (5 studies, 299 patients) was 88% (95% confidence interval (CI): 84-92%, I2: 0%) and for biliary stent ± BS (5 studies, 864 patients) was 97% (CI: 93-100%, I2: 79%). The rate of clinical success in biliary stent ± BS group was significantly higher than BS alone group (OR: 3.91 95% CI: 2.29-6.69, p < 0.001, I2: 13%). The rate of adverse events was numerically lower in biliary stent ± BS group compared to BS alone (3 studies; OR: 0.65 95% CI: 0.41-1.03, p = 0.07) without statistical significance. Low heterogeneity was noted in the analysis. CONCLUSIONS Biliary stent ± BS is more effective in endoscopic management of PCBL compared to BS alone. This may be related to inter-endoscopist variation in completeness of sphincterotomy and post-sphincterotomy edema, which can influence the preferential trans-papillary flow of bile.

Abstract
Background/Aims Multiple outbreaks of multidrug-resistant organisms have been reported worldwide due to contaminated duodenoscopes. In 2015, the United States Food and Drug Administration recommended the following supplemental enhanced surveillance and reprocessing techniques (ESRT) to improve duodenoscope disinfection: (1) microbiological culture, (2) ethylene oxide sterilization, (3) liquid chemical sterilant processing system, and (4) double high-level disinfection. A systematic review and meta-analysis was performed to assess the impact of ESRT on the contamination rates. Methods A thorough and systematic search was performed across several databases and conference proceedings from inception until January 2021, and all studies reporting the effectiveness of various ESRTs were identified. The pooled contamination rates of post-ESRT duodenoscopes were estimated using the random effects model.
Results A total of seven studies using various ESRTs were incorporated in the analysis, which included a total of 9,084 post-ESRT duodenoscope cultures. The pooled contamination rate of the post-ESRT duodenoscope was 5% (95% confidence interval [CI]: 2.3%–10.8%, inconsistency index [I2]=97.97%). Pooled contamination rates for high-risk organisms were 0.8% (95% CI: 0.2%–2.7%, I2=94.96).
Conclusions While ESRT may improve the disinfection process, a post-ESRT contamination rate of 5% is not negligible. Ongoing efforts to mitigate the rate of contamination by improving disinfection techniques and innovations in duodenoscope design to improve safety are warranted.

High-volume, low-mortality units have similar complication rates to others, but have lower FTR rates. Effective response to the deteriorating post-operative patient is therefore critical to reducing surgical mortality. Resilience Engineering might afford a useful perspective for studying how the management of deterioration usually succeeds and how resilience can be strengthened. METHODS We studied the response to the deteriorating patient following emergency abdominal surgery in a large surgical emergency unit, using the Functional Resonance Analysis Method (FRAM). FRAM focuses on the conflicts and trade-offs inherent in the process of response, and how staff adapt to them, rather than on identifying and eliminating error. 31 semi-structured interviews and two workshops were used to construct a model of the response system from which conclusions could be drawn about possible ways to strengthen system resilience. RESULTS The model identified 23 functions, grouped into five clusters, and their respective variability. The FRAM analysis highlighted trade-offs and conflicts which affected decisions over timing, as well as strategies used by staff to cope with these underlying tensions. Suggestions for improving system resilience centred on improving team communication, organisational learning and relationships, rather than identifying and fixing specific system faults. CONCLUSION FRAM can be used for analysing surgical work systems in order to identify recommendations focused on strengthening organisational resilience. Its potential value should be explored by empirical evaluation of its use in systems improvement.

Abstract
Peroral endoscopic myotomy (POEM) in patients with achalasia who are status post bariatric surgery may be technically challenging due to postsurgical scarring and altered anatomy. The aim of the study was to assess the efficacy and safety of POEM for achalasia in patients with prior bariatric surgery. A review of prospectively maintained databases at three tertiary referral centers from January 2015 to January 2021 was performed. The primary outcome of interest was clinical success, defined as a post-treatment Eckardt score ≤ 3 or improvement in Eckardt score by ≥ 1 when the baseline score was <3, and improvement of symptoms. Secondary outcomes were adverse event rates and symptom recurrence. Sixteen patients status post Roux-en-Y gastric bypass (n = 14) and sleeve gastrectomy (n = 2) met inclusion criteria. Indications for POEM were achalasia type I (n = 2), type II (n = 9), and type III (n = 5). POEM was performed either by anterior or posterior approach. The pre-POEM mean integrated relaxation pressure was 26.2 ± 7.6 mm Hg. The mean total myotomy length was 10.2 ± 2.7 cm. The mean length of hospitalization was 1.4 ± 0.7 days. Pre- and postprocedure Eckardt scores were 6.1 ± 2.1 and 1.7 ± 1.8, respectively. The overall clinical success rate was 93.8% (15/16) with mean follow-up duration of 15.5 months. One patient had esophageal leak on postprocedure esophagram and managed endoscopically. Dysphagia recurred in two patients, which was successfully managed with pneumatic dilation with or without botulinum toxin injection. POEM appears to be safe and effective in the management of patients with achalasia who have undergone prior bariatric surgery.

Abstract
Objective To analyze the effectiveness of the pectoralis major myocutaneous (PMMC) flap in preventing pharyngocutaneous fistula (PCF) formation for salvage total laryngectomy patients. Study design Retrospective chart review of all post-surgical laryngectomy patients for a single surgeon. Methods Inclusion criteria were adult patients 18 years and older who were diagnosed with laryngeal cancer and treated with a salvage total laryngectomy. Exclusion criteria were any laryngectomy patient treated without the PMMC flap or those with incomplete medical records. Results A total of 31 patient charts were identified, and 16 remained after exclusion criteria. The patient age range was 42-71 years (mean = 58.19; SD = 8.093). Greater than 85% of patients had T3 and T4 laryngeal cancers. Without PCF group were 13 patients and with PCF group were only three patients. The mean hospital days in without PCF group were 9.54 and in with PCF group were 16.33. Conclusion In this single surgeon’s experience, PCF was prevented by using the PMMC flap in salvage total laryngectomy patients.

Abstract
Introduction/Objective In response to the rapidly evolving COVID-19 pandemic, Sanford Health developed a mobile diagnostic testing program capable of reaching geographically dispersed sites and communities. These mobile laboratories provided on-site testing and sensitive detection of SARS-CoV-2 by leveraging Cepheid’s GeneXpert platform, enabling rapid reporting of results directly to the patient and physician. Aggregation of these results allowed monitoring population infection rates and public health reporting. Methods/Case Report Within 3 weeks of conception, the first mobile unit was designed, engineered and deployed. Key requirements for successful implementation included mobile lab licensure, CLIA certification, COLA enrollment, Quality and Risk assessments, inventory management, lab maintenance and ongoing monitoring. Testing was performed using the Xpert Xpress SARS-CoV-2 test and the population tested were primarily asymptomatic individuals. Results (if a Case Study enter NA) Between May 3rd, 2020 and June 23rd, 2021, a total of 31,148 Xpert Xpress SARS-CoV-2 tests were run across 3 mobile laboratories, with an average of 600 tests performed per week. The percent positivity ranged from 0% to 5.8%, reaching highest positivity in week beginning May 10th, 2020. The average turnaround time from sample collection to result verification was 2.0 hours, and the average time from sample receipt to result verification was under 1 hour. Conclusion Sanford Health’s mobile testing program brings SARS-CoV-2 PCR testing to the community and dramatically reduces the time from sample collection to result reporting compared with traditional testing labs, enabling rapid intervention following a positive result. The flexibility of the GeneXpert platform, including the instrument’s robustness, the independently functioning analyzers, and the wide range of tests available, makes it particularly well suited to mobile laboratories. This program demonstrates the impact of on-site testing and highlights the challenges that were overcome for successful implementation, providing a blueprint to support the development of other mobile laboratories in the US.

Abstract
This paper studies the effects of two different types of distributed-delay coupling in the system of two mutually coupled Kuramoto oscillators: one where the delay distribution is considered inside the coupling function and the other where the distribution enters outside the coupling function. In both cases, the existence and stability of phase-locked solutions is analyzed for uniform and gamma distribution kernels. The results show that while having the distribution inside the coupling function only changes parameter regions where phase-locked solutions exist, when the distribution is taken outside the coupling function, it affects both the existence, as well as stability properties of in- and anti-phase states. For both distribution types, various branches of phase-locked solutions are computed, and regions of their stability are identified for uniform, weak, and strong gamma distributions.

Abstract
Background: Osteoarthritis is most prevalent in the knee and drives the growing incidence of total knee arthroplasty. There is a need to explore non-surgical treatment options to increase the portfolio of alternatives available. The study aimed to determine the clinical response to an autologous bone marrow aspirate concentrate (BMAC) and platelet-rich plasma (PRP) intra-articular injection compared to an active comparator. Methods: The study was a prospective, single-blinded, randomized controlled pilot study. Participants with diagnosed knee osteoarthritis were allocated to one of two treatment groups to receive a BMAC injection immediately followed by a PRP injection or a single injection of Gel-One® crosslinked hyaluronate (HA). Outcomes were assessed at 3, 6, and 12 months post-treatment. Results: Significant improvements were observed in both treatment groups for all Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales with the exception of the symptoms assessment at 12 months in the HA group. BMAC KOOS scores peaked at 12 months, while HA KOOS scores generally peaked at 6 months. The gap in mean scores at 12 months in favor of the BMAC group did not reach statistical significance. Secondary outcomes included a greater reduction in pain at 12 months in the BMAC group (-3.13 points; 95% CI: -3.96, -3.29) compared to the HA group (-1.56 points; 95% CI: -2.59, -0.53; p= 0.02) via the numeric pain rating scale. Conclusions: Results demonstrate that both treatment groups experienced clinically and statistically significant improvement across the KOOS subscales. While BMAC has shown promise in the treatment of knee OA, there is a need for multi-center investigations with larger sample sizes, an extended follow-up, and placebo-based control.

Abstract
We describe an analysis comparing the pp[over ¯] elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of-mass energy of sqrt[s]=1.96 TeV, are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section. The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering for which the significance is between 3.4σ and 4.6σ. The combined significance is larger than 5σ and is interpreted as the first observation of the exchange of a colorless, C-odd gluonic compound.

Abstract
Objective To explore differences in position emission tomography-computed tomography (PET-CT) service provision internationally to further understand the impact variation may have upon cancer services. To identify areas of further exploration for researchers and policymakers to optimize PET-CT services and improve the quality of cancer services. Design Comparative analysis using data based on pre-defined PET-CT service metrics from PET-CT stakeholders across seven countries. This was further informed via document analysis of clinical indication guidance and expert consensus through round-table discussions of relevant PET-CT stakeholders. Descriptive comparative analyses were produced on use, capacity and indication guidance for PET-CT services between jurisdictions. Setting PET-CT services across 21 jurisdictions in seven countries (Australia, Denmark, Canada, Ireland, New Zealand, Norway and the UK). Participants None. Intervention(s) None. Main Outcome Measure(s) None. Results PET-CT service provision has grown over the period 2006–2017, but scale of increase in capacity and demand is variable. Clinical indication guidance varied across countries, particularly for small-cell lung cancer staging and the specific acknowledgement of gastric cancer within oesophagogastric cancers. There is limited and inconsistent data capture, coding, accessibility and availability of PET-CT activity across countries studied. Conclusions Variation in PET-CT scanner quantity, acquisition over time and guidance upon use exists internationally. There is a lack of routinely captured and accessible PET-CT data across the International Cancer Benchmarking Partnership countries due to inconsistent data definitions, data linkage issues, uncertain coverage of data and lack of specific coding. This is a barrier in improving the quality of PET-CT services globally. There needs to be greater, richer data capture of diagnostic and staging tools to facilitate learning of best practice and optimize cancer services.

Abstract
BACKGROUND Soldiers are exposed to significant repetitive head trauma, which may disrupt functional and structural brain connectivity patterns. PURPOSE/HYPOTHESIS Integrate resting-state functional MRI (rs-fMRI) and diffusion tensor imaging (DTI) to characterize changes in connectivity biomarkers within Canadian Special Operations Forces (CANSOF), hypothesizing that alterations in architectural organization of cortical hubs may follow chronic repetitive head trauma. METHODS Fifteen CANSOFs with a history of chronic exposure to sub-concussive head trauma and concussive injuries (1.9 ± 2.0 concussions (range: [0-6])), as well as an equal age-matched cohort of controls (CTLs) were recruited. BOLD-based rs-fMRI was combined with DTI to reconstruct functional and structural networks using independent component analyses and probabilistic tractography. Connectivity markers were computed based on the distance between functional seeds to assess for possible differences in injury susceptibility of short- and long-range connections. RESULTS/DISCUSSION Significant hyper- and hypo-connectivity differences in cortical connections were observed suggesting that chronic head trauma may predispose soldiers to changes in the functional organization of brain networks. Significant structural alterations in axonal fibers directly connecting disrupted functional nodes were specific to hyper-connected long-range connections, suggesting a potential relationship between axonal injury and increases in neural recruitment following repetitive head trauma from high-exposure military duties.

Abstract
Background The development of research skills is an important aspect of undergraduate medical training that facilitates the practice of evidence-based medicine. The inclusion of research training into undergraduate medical curricula can take various formats and is compulsory for all students at the Nelson R. Mandela School of Medicine (NRMSM). The evaluation of this training is important, both to ensure that students obtain the required research skills and to improve the quality of the training. Aim The aim of this study was to evaluate undergraduate medical students’ and staff learning, engagement and experiences in the training and assessment of third-year research projects. Setting This research was conducted at NRMSM, South Africa. Methods Questionnaires were administered to third-year medical students after they completed their research project poster presentations and to the staff who assessed the presentations. Responses to the learning process, group work, alignment between module outcomes and assessment and the benefits of poster presentations were assessed. Results A total of 215 students and 10 staff completed the questionnaire. Many students reported having enjoyed learning about research (78%) and that the training activities facilitated their understanding of the research process (84%). The majority of students (86%) and staff (80%) perceived the posters as an effective way to demonstrate students’ ability to collect, analyse and interpret data. Conclusion Staff and students viewed the research process positively and reported that the poster presentations were an effective way to assess research.

Abstract
BACKGROUND & AIMS Patients who chronically use alcohol, marijuana, or opioids, or suffer from post-traumatic stress disorder (PTSD), can be difficult to sedate with midazolam and fentanyl, and often are referred for monitored anesthesia care during endoscopy. Nurse-administered propofol continuous infusion sedation (NAPCIS), which confers the benefit of propofol-based sedation without the added expense of anesthesia, is effective and safe for sedation of healthy patients. We investigated whether NAPCIS also is effective for patients who are difficult to sedate. METHODS We performed a retrospective study of patients who underwent upper endoscopy or colonoscopy with NAPCIS at a single center from January 2018 through April 2018. We reviewed records from patients who were heavy users of alcohol (n = 105), daily users of marijuana (n = 267) or opioids (n = 178), had a diagnosis of PTSD (n = 91), or were none of these (controls, n = 786). We compared mean fentanyl and propofol doses (adjusted for body weight), procedure and recovery times, procedure success rates, and adverse events. RESULTS Compared with the controls, the marijuana group required higher mean adjusted sedative doses for colonoscopies (0.6 vs 0.4 mcg/kg fentanyl and 5.0 vs 4.7 mg/kg propofol; P ≤ .025 for both) and upper endoscopies (0.8 vs 0.3 mcg/kg fentanyl and 3.7 vs 3.2 mg/kg propofol; P ≤ .021 for both), the PTSD group required a higher dose of fentanyl for colonoscopies (0.6 vs 0.4 mcg/kg; P = .009), and the alcohol group required a higher dose of fentanyl for upper endoscopies (0.7 vs 0.3 mcg/kg; P < .001). Procedure success rates were high (95.1%-100%) and did not differ significantly between the difficult-to-sedate groups and controls; mean procedure times (7.0-9.0 minutes for upper endoscopies, 21.1-22.9 minutes for colonoscopies) and recovery times (22.5-29.6 minutes) also were similar among groups. Upper endoscopies were associated with lower sedative doses and shorter procedure and recovery times than colonoscopies. Sedation-related adverse events were rare in all groups (only 26 cases total), and there were no serious complications or deaths. CONCLUSIONS NAPCIS seems to be a safe and effective means of providing sedation for endoscopy to patients who may be difficult to sedate owing to alcohol, marijuana, or opioid use, or PTSD.

Abstract
Antiferromagnetic materials can host spin-waves with polarizations ranging from circular to linear depending on their magnetic anisotropies. Until now, only easy-axis anisotropy antiferromagnets with circularly polarized spin-waves were reported to carry spin-information over long distances of micrometers. In this article, we report long-distance spin-transport in the easy-plane canted antiferromagnetic phase of hematite and at room temperature, where the linearly polarized magnons are not intuitively expected to carry spin. We demonstrate that the spin-transport signal decreases continuously through the easy-axis to easy-plane Morin transition, and persists in the easy-plane phase through current induced pairs of linearly polarized magnons with dephasing lengths in the micrometer range. We explain the long transport distance as a result of the low magnetic damping, which we measure to be ≤ 10-5 as in the best ferromagnets. All of this together demonstrates that long-distance transport can be achieved across a range of anisotropies and temperatures, up to room temperature, highlighting the promising potential of this insulating antiferromagnet for magnon-based devices.
