Abstract
BACKGROUND To evaluate the effect of a 1 mg/dl reduction in uric acid (UA) on cardiovascular events and mortality in patients treated with sodium-glucose cotransporter 2 (SGLT2) inhibitors. RESEARCH DESIGN AND METHODS We performed a systematic review of the MEDLINE and EMBASE databases searched up to 30 June 2023 (PROSPERO, CRD42022355479) to identify large-scale SGLT2 inhibitor trials. Random-effects meta-analyses were used to pool the estimates. RESULTS In total, five SGLT2 inhibitor trials (31 535 patients, 54% with heart failure) were analysed. Over a median follow-up of 2.2 years, the mean reduction in UA was -0.79 mg/dl (95% confidence interval (CI), -1.03 to -0.54). Every 1 mg/dl reduction in UA was associated with a significantly lower risk of a composite of cardiovascular death and hospitalization for heart failure [hazard ratio, 0.64 (95% CI, 0.46-0.88)] and hospitalization for heart failure (0.68; 95% CI, 0.62-0.74), with a similar risk of mortality. CONCLUSIONS SGLT2 inhibitors reduced UA levels and cardiovascular events independently of heart failure status.

Abstract
Background: GWAS discoveries often pose a significant challenge in terms of understanding their underlying mechanisms. Further research, such as an integration with expression quantitative trait locus (eQTL) analyses, are required to decipher the mechanisms connecting GWAS variants to phenotypes. An eQTL analysis was conducted on genes associated with low-density lipoprotein (LDL) cholesterol and its subclasses, with the aim of pinpointing genetic variants previously implicated in GWAS studies focused on lipid-related traits. Notably, the study cohort consisted of African Americans, a population characterized by a heightened prevalence of hypercholesterolemia. Methods: A comprehensive differential expression (DE) analysis was undertaken, with a dataset of 17,948 protein-coding mRNA transcripts extracted from the whole-blood transcriptomes of 416 samples to identify mRNA transcripts associated with LDL, with further granularity delineated between small LDL and large LDL subclasses. Subsequently, eQTL analysis was conducted with a subset of 242 samples for which whole-genome sequencing data were available to identify single-nucleotide polymorphisms (SNPs) associated with the LDL-related mRNA transcripts. Lastly, plausible functional connections were established between the identified eQTLs and genetic variants reported in the GWAS catalogue. Results: DE analysis revealed 1,048, 284, and 94 mRNA transcripts that exhibited differential expression in response to LDL, small LDL, and large LDL, respectively. The eQTL analysis identified a total of 9,950 significant SNP-mRNA associations involving 6,955 SNPs including a subset 101 SNPs previously documented in GWAS of LDL and LDL-related traits. Conclusion: Through comprehensive differential expression analysis, we identified numerous mRNA transcripts responsive to LDL, small LDL, and large LDL. Subsequent eQTL analysis revealed a rich landscape of eQTL-mRNA associations, including a subset of eQTL reported in GWAS studies of LDL and related traits. The study serves as a testament to the important role of integrative genomics in unraveling the enigmatic GWAS relationships between genetic variants and the complex fabric of human traits and diseases.

Abstract
Bacterial Leaf Blight of rice (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is a major threat for food security in many rice growing countries including Burkina Faso, where the disease was first reported in the 1980's. In line with the intensification of rice cultivation in West-Africa, BLB incidence has been rising for the last 15 years. West-African strains of Xoo differ from their Asian counterparts as they (i) are genetically distant, (ii) belong to new races and, (iii) contain reduced repertoires of Transcription Activator Like (TAL) effector genes. In order to investigate the evolutionary dynamics of Xoo populations in Burkina Faso, 177 strains were collected from 2003 to 2018 in three regions where BLB is occurring. Multilocus VNTR Analysis (MLVA-14) targeting 10 polymorphic loci discriminated 24 haplotypes and showed that Xoo populations were structured according to their geographical localization and year of collection. Considering their major role in Xoo pathogenicity, we assessed the TAL effector repertoires of the 177 strains upon RFLP-based profiling. Surprisingly, an important diversity was revealed with up to eight different RFLP patterns. Finally, comparing neutral vs. tal effector gene diversity allowed to suggest scenarios underlying the evolutionary dynamics of Xoo populations in Burkina Faso, which is key to rationally guide the deployment of durably resistant rice varieties against BLB in the country.

Abstract
Advances in technologies including omics, apps, imaging, sensors, and big data are increasingly being integrated into research by nurse scientists, but the impact on improving health equity is still unclear. In this article, nursing research faculty from one institution discuss challenges and opportunities experienced when integrating various technologies into their research aimed at promoting health equity. Using exemplars from faculty experiences, a three-pronged approach to keeping patients and communities and the goal of health equity central in research while incorporating advancing technologies is described. This approach includes establishing long-term engagement with populations underrepresented in research, adopting strategies to increase diversity in study participant recruitment, and training and collaboration among a diverse workforce of educators, clinicians, and researchers. Training nurse scientists in integrating data and technology for advancing the science on health equity will shift the culture of how we understand, collaborate, and grow with the communities in which we train and practice as nurse scientists.

Abstract
Magnetic field aligned filaments such as blobs and edge localized mode filaments carry significant amounts of heat and particles to the plasma facing components and they decrease their lifetime. The dynamics of these filaments determine at least a part of the heat and particle loads. These dynamics can be characterized by their translation and rotation. In this paper, we present an analysis method novel for fusion plasmas, which can estimate the angular velocity of the filaments on frame-by-frame time resolution. After pre-processing, the frames are two-dimensional (2D) Fourier-transformed, then the resulting 2D Fourier magnitude spectra are transformed to log-polar coordinates, and finally the 2D cross-correlation coefficient function (CCCF) is calculated between the consecutive frames. The displacement of the CCCF's peak along the angular coordinate estimates the angle of rotation of the most intense structure in the frame. The proposed angular velocity estimation method is tested and validated for its accuracy and robustness by applying it to rotating Gaussian-structures. The method is also applied to gas-puff imaging measurements of filaments in National Spherical Torus Experiment plasmas.

Abstract
Junior investigators from groups underrepresented in the biomedical workforce confront challenges as they navigate the ranks of academic research careers. Biochemical research needs the participation of these researchers to adequately tackle critical research priorities such as cardiovascular health disparities and health inequities. We explore the inadequate representation of underrepresented minority investigators and the historical role of systemic racism in impacting their poor career progression. We highlight challenges these investigators face, and opportunities to address these barriers are identified. Ensuring adequate recruitment and promotion of underrepresented biomedical researchers fosters inclusive excellence and augments efforts to address health inequities. The Programs to Increase Diversity among Individuals Engaged in Health-Related Research (PRIDE), funded by the National Heart, Lung, and Blood Institute (NHLBI), is a pilot program by the National Institutes of Health (NIH) that aims to address these challenges yet, only a limited number of URM can be accepted to PRIDE programs. Hence the need for additional funding for more PRIDE or PRIDE-like programs. Here we aim to examine the challenges underrepresented minority biomedical investigators face and describe ongoing initiatives to increase URM in biomedical research using the NHLBI-PRIDE program as a focus point.

Abstract
System-on-chip millimeter wave integrated circuit technology is used on the two-dimensional millimeter-wave imaging reflectometer (MIR) upgrade for density fluctuation imaging on the DIII-D tokamak fusion plasma. Customized CMOS chips have been successfully developed for the transmitter module and receiver module array, covering the 55-75 GHz working band. The transmitter module has the capability of simultaneously launching eight tunable probe frequencies (>0 dBm output power each). The receiver enclosure contains 12 receiver modules in two vertical lines. The quasi-optical local oscillator coupling of previous MIR systems has been replaced with an internal active frequency multiplier chain for improved local oscillator power delivery and flexible installation in a narrow space together with improved shielding against electromagnetic interference. The 55-75 GHz low noise amplifier, used between the receiver antenna and the first-stage mixer, significantly improves module sensitivity and suppresses electronics noise. The receiver module has a 20 dB gain improvement compared with the mini-lens approach and better than -75 dBm sensitivity, and its electronics noise temperature has been reduced from 55 000 K down to 11 200 K. The V-band MIR system is developed for co-located multi-field investigation of MHD-scale fluctuations in the pedestal region with W-band electron cyclotron emission imaging on DIII-D tokamak.

Abstract
Forward modeling is used to interpret inversion patterns of the pedestal-Scrape of Layer (SOL) Electron Cyclotron Emission (ECE) in DIII-D H-mode experiments. The modeling not only significantly improves the ECE data interpretation quality but also leads to the potential measurements of (1) the magnetic field strength |B| at the separatrix, (2) the pedestal |B| evolution during an inter-Edge Localized Mode (ELM) period, and (3) the pedestal Magnetohydrodynamics (MHD) radial structure. The ECE shine-through effect leads to three types of pedestal-SOL radiation inversions that are discussed in this paper. The first type of inversion is the non-monotonic Te,rad profile with respect to the major radius. Using the ECE frequency at the minimum Te,rad, the inversion can be applied to measure the magnetic field |B| at the separatrix and calibrate the mapping of the ECE channels with respect to the separatrix. The second type of inversion refers to the opposite phase between the radiation fluctuations δTe,rad at the pedestal and SOL. This δTe,rad phase inversion is sensitive to density and temperature fluctuations at the pedestal foot and, thus, can be used to qualitatively measure the MHD radial structure. The third type of inversion appears when the pedestal and SOL Te,rad evolve in an opposite trend, which can be used to infer the pedestal |B| field change during an inter-ELM period. The bandwidth effect on measuring δTe,rad due to pedestal MHD is also investigated in the radiation modeling.

Abstract
BACKGROUND Prior assessment of the economic burden of TB showed high risk of catastrophic costs in Burkina Faso. A decade later, the National TB Programme conducted the first national patient cost survey, establishing a baseline for future policymaking.METHODS A national TB patient cost survey was conducted early 2020. Following WHO methods, a structured questionnaire was administered to 465 patients (20 clusters) to report on the direct and indirect costs of TB, household income and coping strategies adopted by the TB-affected families. The share of households facing catastrophic costs was assessed. Multiple logistic regression was performed to identify factors associated with catastrophic costs due to TB.RESULTS One in two (54.4%) TB-affected households in Burkina Faso faced catastrophic costs, resulting in major improvements over the past decade. On average, households incurred in US$962.64 per episode of care (respectively US$741.7, US$122.3 and US$98.6 for indirect, direct medical and non-medical costs), leaving substantial costs requiring mitigation strategies (39.8%). Major risk factors were associated with hospitalisation and wealth-related variables. Job loss, food insecurity and other social consequences were also experienced.CONCLUSION Despite progress, reducing the End TB indicator of catastrophic costs remains central to policymaking to ensure effective financial protection in Burkina Faso.

Abstract
Objectives: Older adults have been disproportionately affected by COVID-19. The primary goal of this study is to determine the socioeconomic effects on psychosocial factors among low-income independent-living older adults, in an urban setting, during the COVID-pandemic. Methods: Participants were recruited through Virginia Commonwealth University’s Richmond Health and Wellness Program. Telephone surveys (n=100) were conducted using the Epidemic – Pandemic Impacts Inventory Geriatric with the Racial/Ethnic Discrimination addendum. Responses were analyzed for income and education effects across seven domains: home life, social activities/isolation, economic, emotional health-wellbeing, physical health, COVID-infection history, and positive change behaviors/experiences. Results: The sample population was between 51 and 87 years of age, 88% were Black, 57% reported incomes of $10,000/year or less, and 60% reported a high-school education or less. There were income effects for social activities/isolation (f = 3.69, p<.05) and positive change (f = 8.40, p<.01), and education effects for COVID History (f = 4.20, p <.04). Discussion: Overall results highlight the social patterns for a diverse sample of low-income urban older adults; education and income are identified as risk factors for social losses, COVID-infection experiences, racial/ethnic discrimination during the COVID-pandemic, and positive change behaviors.

Abstract
Taking a phenomenological approach, this qualitative study describes the lived experiences of low-income older adults during the COVID-19 pandemic. A socio-ecological model was used to organize the five identified themes describing the lived experience: socio-economic context, Black Lives Matter and the politics of race, COVID and polarized views of COVID, interpersonal context (social connections), and individual context (feelings, beliefs, and behaviors). Study findings illustrate the intersectionality of contextual influences on the experience of low-income older adults. Study participants demonstrated remarkable resilience and coping strategies developed in response to the challenges they experienced throughout their lifetime which benefited them when faced with the pandemic, social unrest, and political events that took place in 2020. This study highlights the importance of understanding the larger context of COVID-19 which has significant implications for policy makers and public health leaders.

Abstract
INTRODUCTION Hip prosthetic surgery is a commonly performed procedure in orthopedic trauma. It has changed the prognosis of traumatic, degenerative and inflammatory hip diseases. OBJECTIVE The aim of this work was to evaluate the functional and anatomical results of a series of total hip replacements in our department in the short and medium term and to compare them with the literature. PATIENTS AND METHODS This was a retrospective descriptive and analytical study of a series of 96 total hip replacements performed at the University Hospital of Kati, from January 2019 to December 2021. Functional discomfort was assessed in all patients before and after surgery. The prostheses used were of the Aston, AK, Surgival, Evolutus and Sharma types. The anatomical results were assessed by radiological criteria and the functional results by Postel Merle d'Aubigné criteria. RESULTS In our study, 96 hips were operated on by total prosthesis in 91 patients, including five bilateral cases. The patients were 49 men and 42 women. The average age was 46.9 years. Coxarthrosis associated with necrosis of the femoral head was the most frequent indication for arthroplasty (n=51), followed by femoral neck fracture (n=26). The inclination of the cup was anatomical in 73.3% of cases. The mean femoral offset was 44.1 mm with extremes of 26 and 59 mm. Cup anteversion was normal in 79.4% of cases. The mean preoperative PMA score increased from 5.2 (0 and 15) to 16.9 (4 and 18) late postoperatively. Our results were satisfactory in 89% of cases. CONCLUSION Total hip arthroplasty allows, in the vast majority of cases, to recover indolence and perfect functionality of the hip.

Abstract
There is a growing emphasis to use a transdisciplinary team approach to accelerate innovations in science to solve complex conditions associated with aging. However, the optimal organizational structure and process for how to accomplish transdisciplinary team science are unclear. In this study, we illustrate our team’s experience using transdisciplinary approaches to solve challenging and persistent problems for older adults living in urban communities. We describe our challenges and successes using the National Institutes of Health four-phase model of transdisciplinary team-based research. Using a de-identified survey, the team conducted an internal evaluation to identify features that created challenges including structural incongruities, interprofessional blind spots, group function, and group dynamics. The team then identified responses to address the features that created challenges and determined indicators for success. Indicators for success were identified by the team as a place for continued evaluation of the teams’ collaborative effectiveness, transdisciplinary integration, and impact on the university and aging community. This work resulted in the creation of the team’s Transdisciplinary Conceptual Model. This model became essential to understanding the complex interplay between societal factors, community partners, and academic partners. Conducting internal evaluations of transdisciplinary team processes is integral for teams to move beyond the multi- and interdisciplinary niche and to reach true transdisciplinary success. More research is needed to develop measures that assess team transdisciplinary integration. Once the process of transdisciplinary integration can be reliably assessed, the next step would be to determine the impact of transdisciplinary team science initiatives on aging communities.

Abstract
Introduction Le 13/03/20, Mayotte déclare son premier cas de Covid-19. Le contexte socio-économique précaire rend inconcevable l’application des recommandations de prévention. Bien que la moitié de la population ait moins de 18 ans ; chez les adultes, la prévalence des facteurs de risque de formes graves fait redouter une saturation de l’unique hôpital de l’île : 38 % d’HTA, 12 % de diabète tandis que l’IMC moyen est de 26,9 kg/m2. Matériels et méthodes Afin de comprendre la dynamique et la sévérité du Covid-19 à Mayotte, plusieurs dispositifs de surveillance ont été mis en place. Ce travail décrit l’évolution épidémique du 9/03/20 au 14/03/21 en distinguant deux vagues différentes du fait de l’émergence de variants: 2020 (9/03/20-31/12/20) versus 2021 (01/01/21-14/03/21). Résultats L’épidémie a débuté en mars 2020 avec un pic en mai (taux d’incidence (TI) de 133/100000 hbts). L’âge médian des cas était de 36 ans et la plupart d’entre eux était sans activité professionnelle. Le TI a diminué pour passer début juillet, sous le seuil d’alerte, suggérant une accalmie durant l’hiver austral. Cette première vague s’est avérée relativement peu sévère avec un maximum de cas hospitalisés en S21 : 51 patients hospitalisés dont 11 en réanimation. La circulation virale a continué sans impact sanitaire majeur jusqu’en décembre 2020 où l’Afrique du Sud a signalé l’émergence du variant 501Y.V2. Quelques semaines après les Comores, Mayotte enregistrait une dégradation rapide et intense de la situation: doublement du TI, triplement du taux de positivité Sars-Cov-2 (TP) entre mi-décembre et mi-janvier, y compris chez les 0-14 ans. En S6-2021, le TI a atteint un pic (894/100000 hbts) tout comme le TP culminant à 28 %. Deux enquêtes flash en février ont montré la part majoritaire d’un variant avec la mutation 501Y, représentant 87 % (150/172) des échantillons analysés par criblage. Les indicateurs hospitaliers témoignaient de la sévérité de cette nouvelle vague avec un pic atteint en S18-2021 : 148 patients hospitalisés dont 27 en réanimation, majoritairement des formes oxygéno-requérentes. En 2021, 149 cas ont été admis en réanimation contre 104 en 2020 (sex ratio H/F = 1,9). Parmi les patients présentant une forme pulmonaire, le profil des cas admis en réanimation en 2021 a changé par rapport à 2020 : ils étaient significativement plus jeunes (57 vs 62 ans) et présentaient un profil de comorbidités différent. Au total, en un an, 18899 cas ont été confirmés biologiquement et 253 patients admis en réanimation: ils correspondaient à 203 cas de formes pulmonaires, 46 cas de portage asymptomatique et 14 cas de syndrome inflammatoire multi-systématique associé à une infection par le Sars-Cov-2. En 2021, 88 patients sont décédés contre 55 en 2020; âges médians respectifs de 73 et 64 ans. Conclusion Le confinement de février 2021 s’est suivi d’une inversion de la tendance épidémique. Fin mars, l’épidémie se poursuit avec un TI de 63/100000 hbts. Alors que moins de 5000 personnes ont été vaccinées à deux doses, la vigilance est de mise pour ce territoire vulnérable.

Abstract
Dynamics of fast transient events are challenging to be analyzed with high time resolution. Such events can occur in fusion plasmas such as the filaments during edge-localized modes (ELMs). In this paper, we present a robust method-the spatial displacement estimation-for estimating the displacements of structures with fast dynamics from high spatial and time resolution imaging diagnostics [e.g., gas-puff imaging (GPI)] with sampling time temporal resolution. First, a background suppression method is shown, which suppresses the slowly time-evolving and spatially non-uniform background in the signal. In the second step, a two-dimensional polynomial trend subtraction method is presented to tackle the remaining polynomial order trend in the signal. After performing these pre-processing steps, the spatial displacement of the propagating structure is estimated from the two-dimensional spatial cross-correlation coefficient function calculated between consecutive frames. The method is tested for its robustness and accuracy by simulated Gaussian events and spatially displaced random noise. An example application of the method is presented on propagating ELM filaments measured by the GPI system on the National Spherical Torus Experiment spherical tokamak.

Abstract
A scalable system for real-time analysis of electron temperature and density based on signals from the Thomson scattering diagnostic, initially developed for and installed on the NSTX-U experiment, was recently adapted for the Large Helical Device and operated for the first time during plasma discharges. During its initial operation run, it routinely recorded and processed signals for four spatial points at the laser repetition rate of 30 Hz, well within the system's rated capability for 60 Hz. We present examples of data collected from this initial run and describe subsequent adaptations to the analysis code to improve the fidelity of the temperature calculations.

Abstract
OBJECTIVE This study aims to determine whether current tobacco and/or alcohol use is associated with setting preferences for seeking support for substance use (SU) and mental health (MH) services to African Americans ages 50 and older. METHODS Data from 368 African American individuals (aged 50+) who participated in a community-based needs assessment survey were used. Preferences included community-based (e.g., health centers) and traditional settings (e.g., doctor's office). SU was measured as a categorical variable detailing past-month use of conventional cigarettes and alcohol graded by risk levels. Logistic regression models tested the associations between SU and setting preference before and after adjusting for the influence of self-reported MH diagnoses. RESULTS Prior to adjustment for the influence of MH outcomes, high-risk use of tobacco and alcohol in the past month was associated with a lower odds of preferring MH/SU support in traditional settings (OR = 0.23, 95% CI = 0.06-0.85) compared to participants engaged in no-/low- risk substance use. This association was no longer significant after accounting for the influence of mental health symptoms and covariates. DISCUSSION These results provide preliminary evidence that mental health outcomes mediate the association between substance use and setting preference for seeking MH/SU support in traditional settings. TRANSLATIONAL SIGNIFICANCE This exploratory study encourages additional investigation of the association between substance use, setting preferences, and the likelihood of seeking treatment in community health centers using larger sample sizes. Additional opportunities to offer mental health/substance use support to African American older adults within clinical settings should be explored.

Abstract
Older adults and racial minorities are overrepresented in homeless populations. Shelter and housing options for homeless older adults who have complex health and social needs are necessary, but not readily available. Older homeless adults that require, but do not receive, health-sensitive, age-sensitive, and racial equity housing, remain vulnerable to poor outcomes and premature mortality. Accordingly, this study examines the development of a coalition to better address older adult homelessness within a racial equity framework. A community coalition was established to better address older adult homelessness within the lens of age-sensitivity and racial equity, due to a disconnect between healthcare and senior housing placement programs, creating unaddressed multifaceted health issues/complications. The community coalition development is described, including the coalition process, activities, and outcomes. Local rehoused older adults are also interviewed and described to better understand their central life circumstances.

Abstract
Monolithic, millimeter wave "system-on-chip" technology has been employed in chip heterodyne radiometers in a newly developed Electron Cyclotron Emission Imaging (ECEI) system on the DIII-D tokamak for 2D electron temperature and fluctuation diagnostics. The system employs 20 horn-waveguide receiver modules each with customized W-band (75-110 GHz) monolithic microwave integrated circuit chips comprising a W-band low noise amplifier, a balanced mixer, a ×2 local oscillator (LO) frequency doubler, and two intermediate frequency amplifier stages in each module. Compared to previous quasi-optical ECEI arrays with Schottky mixer diodes mounted on planar antennas, the upgraded W-band array exhibits >30 dB additional gain and 20× improvement in noise temperature; an internal eight times multiplier chain is used to provide LO coupling, thereby eliminating the need for quasi-optical coupling. The horn-waveguide shielding housing avoids out-of-band noise interference on each module. The upgraded ECEI system plays an important role for absolute electron temperature and fluctuation measurements for edge and core region transport physics studies. An F-band receiver chip (up to 140 GHz) is under development for additional fusion facilities with a higher toroidal magnetic field. Visualization diagnostics provide multi-scale and multi-dimensional data in plasma profile evolution. A significant aspect of imaging measurement is focusing on artificial intelligence for science applications.

Abstract
Objective The purpose of this study was to analyse the socio-anthropological determinants (representations, beliefs, practices and perceptions of health services) of the high prevalence of obstetric fistulas in Guinea. Patients and methods From January 15 to February 15, 2018, we carried out a qualitative study in three health centres (one urban and two rural). The study focused on biological mothers who attended the centres to get vaccinated their children. The data were collected by semi-structured individual interview. Results None of the 42 respondents could link the occurrence of obstetric fistulas and obstructed labour. Participants at all three study sites believed that obstructed labour and obstetric fistula have a mystical origin. In Kissidougou, the respondents thought that obstructed labour and obstetric fistulas are caused either by soubaya, sorcery in Malinké or the evil spell korte in Malinké cast by an enemy, or the bad behaviour of the parturient which means either she practices adultery or if she behaves disrespectfully towards elders. In Dubréka, the respondents linked the occurrence of labour dystocia and obstetric fistula to witchcraft koromikhi in Sousou. In Labé, some respondents thought that obstructed labour and obstetric fistula are due to divine punishment in local dialect lette Allah when the woman does not respect her husband or has contracted the pregnancy out of the legal union. Others deemed that childbirth is difficult because of the narrowness of the delivery route in Fulani lawol ngol no faadhi in parturients who do not have sex during pregnancy or when the woman had not adequately had female circumcision, in local dialect o suuwaaki laabhi which means, part of the clitoris was left in place during the excision. The majority of respondents had a poor perception of health services (male staff, lack of privacy, poor hygiene, abuse). Several cultural practices (early wedlocks, genital mutilations, dietary restrictions, home deliveries) also induce obstetric fistulas. Conclusion Respondents' cultural beliefs and practices regarding childbirth limit women's attendance at maternity hospitals during childbirth and favour obstetric fistulas.

Abstract
An Electron Cyclotron Emission Imaging (ECEI) data analysis module has been developed for the OMFIT platform to accommodate the needs of users at the DIII-D tokamak for physics applications. The user can easily access the ECEI spatial observation windows in the plasma that are calculated based on the automatically retrieved hardware setup and available DIII-D equilibria, perform spectral analysis, and obtain 2D electron temperature fluctuation images. The module provides a powerful data post-processing package for extracting important physics parameters from the 2D measurements, including the radial structure and poloidal mode number of Alfven eigenmodes, as well as the frequency-vs-wavenumber dispersion relationship of broadband MHD. The module propagates characterized synthetic fluctuations for the user, so one can perform forward modeling tasks with simple analytical fluctuations.

Abstract
BACKGROUND Friedreich's ataxia (FA) is a rare autosomal recessive mitochondrial disease most commonly due to a triplet repeat expansion guanine-adenine-adenine (GAA) in the FXN gene. Cardiac disease is the major cause of death, patients with reduced left ventricular ejection fraction (LVEF) having the worse prognosis. Longitudinal strain (LS) appeared to be a better predictor of outcome than LVEF in different diseases. We compared the prognostic value of LS measured from the 4 chambers view to LVEF. METHODS From 2003 to 2017 consecutive patients with FA were included and LS analysis was retrospectively performed. RESULTS We studied 140 patients, with a median age of 34 (26-41) years (Q1-Q3) with age at onset of 14 (11-19) years and GAA repeats on the shorter allele of 600 (467-783) pb. Mean LS was 19.9 ± 5.0% and LVEF 64 ± 8%. After a mean follow-up of 7.4 ± 3.9 years, 14 patients died. In univariate Cox analysis, all-cause mortality was associated with: LS (HR 0.83; 95%CI, 0.75-0.91, p = 0.0002), LVEF (HR 0.30; 95%CI, 0.19-0.49, p < 0.0001), GAA repeats on the shorter allele (HR 1.29; 95%CI, 1.10-1.51, p = 0.002), age at onset (HR 0.87; 95%CI, 0.77-0.98, p = 0.018), LVSystolic Diameter (HR 1.17; 95%CI, 1.09-1.26, p < 0.0001), LVMass index (HR 1.02; 95%CI, 1.00-1.04, p = 0.027), and LVDiastolic Diameter (HR1.12; 95%CI, 1.01-1.23, p = 0.028). In multivariate analysis, LVEF was the only independent predictor of mortality (HR 0.41; 95%CI, 0.23-0.74, p = 0.0029). CONCLUSION In FA, LS was not an independent predictor of mortality, LVEF remained the only independent predictor in the present study.

Background
Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is associated with complex spatial and temporal right ventricular (RV) wall motion abnormalities. While cardiac magnetic resonance (CMR) is the gold-standard imaging technique, its diagnosic performance remains suboptimal and additional CMR biomarkers reflecting ARVC pathophysiology are needed.
Purpose
To evaluate the performance of a CMR feature-tracking (FT)-derived parameter combining both longitudinal and radial RV deformation and motion for the characterization of RV wall motion abnormalities in ARVC.
Methods
Thirty-nine patients with definite or borderline ARVC (median age 45 years, interquartile range 31–51, 56% males) were compared to 20 healthy controls with comparable age, sex and weight distributions. All subjects had 1.5T CMR including short axis and 4-chamber views steady-state free precession acquisitions. A custom FT software adapted to RV wall segmentation and tracking was used to assess RV wall deformation and motion in the 3 space directions resulting in: 1) global longitudinal strain (GLS) estimated on the 4 chamber view from the RV free wall, 2) basal circumferential strain (BCS) and radial motion fraction (BRMF) estimated as an average of short-axis slices comprised in the RV third basal portion. To capture the complex RV motion in ARCV, a longitudinal to radial strain loop (LRSL) was displayed and its area was calculated.
Results
The ARVC group comprised 28 (72%) patients with definite and 11 (28%) with borderline diagnosis . As compared to controls, LVEF and RVEF were significantly lower in ARVC patients (61(interquartile range (IQR) 52-71) vs. 71%(IQR 55-88) , p = 0.03 and 47%(IQR 16-63) vs. 57%(IQR 49-63) , p = 0.02, respectively), LVEF remaining within normal range limits. While there was no significant difference in RV GLS between ARVC patients and controls (median -17.7%(IQR -24–15) vs. -17.5%(IQR -20.1–15.2), p = 0.67) , BCS and BRMF were significantly lower in ARVC patients vs. controls [-7.5%(IQR -12.3–8.4.) vs. -9.8%(IQR -13.8–8.6.), p = 0.004 and -12.2(IQR -14.4–8.7.) vs. -14.9%(IQR -16.6–13.2) p = 0.0007, respectively] . The LRSL area was significantly and markedly lower in ARVC patients vs. controls [70.6 (IQR 16.3-63.1) vs. 144.1 (IQR 110.4-251.3), p = 0.0002] . LRSL area outperformed RVEF, BCS and BRS in separating ARVC from controls (area under receiving operator characteristics curve 0.82 vs. 0.78, 0.73 and 0.78, respectively).
Conclusion
In ARVC, a FT-derived parameter combining longitudinal and radial RV wall deformation and motion provided better discrimination of ARVC patients from controls than conventional FT measurements. Its implementation in clinical practice may bolster CMR performance to characterize ARVC wall motion abnormalities.

Abstract
OBJECTIVES the purpose of this work was to describe the epidemiological, clinical, paraclinical and therapeutic aspect of surgical treatment of chronic osteomyilitis of limbs. PATIENTS METHODS it was a retrospective study over a period of 12 years, from January 2003 to December 2014. It covered all cases of chronic osteomyelitis osteonecrosis treated our service. RESULTS The authors report the results of the surgical treatment of a series 56 patients operated on for chronic limb osteomyelitis. The mean age was 20.7 years with extremes of 6 months and 56 years. The tibia and femur were the most affected segments. Staphylococcus aureus was the most frequently found germ, 80% of the cases. We obtained complete healing with total cure in 68% of cases and recurrence of suppuration in 32% of cases. CONCLUSION Chronic osteomyelitis of limbs is a frequent pathology in Africa. Staphylococcus aureus was the most frequently found germ. Surgery in a time seems a good alternative. The rate of recurrence of the suppuration remains high.

Abstract
The use of drugs is not solely determined by its therapeutic properties but refers to diversions of these properties. OBJECTIVE To assess the level of knowledge of the diversion of drugs for abortifacient purposes among hairdressers and seamstresses of the suburb of Togblékopé. MATERIAL AND METHOD We conducted a cross-sectional study among hairdressers and seamstresses living in Togblékopé, a suburb on the outskirts of the city of Lomé. RESULTS Of the 114 respondents, 74.6% knew that drugs were diverted for abortion, mostly among older young people, singles and apprentices. In addition, 70.6% reported having at least once attended a drug abortion by someone. Thus, drugs such as paracetamol, chloroquine and acetylsalicylic acid have been reported for abortifacient purposes' diversion, most often purchased on the street and responsible for serious side effects. CONCLUSION This study has highlighted the knowledge of drugs' use for abortifacient purposes among hairdressers and seamstresses. It is necessary to carry out actions that will aim at teaching the risks of drug intoxication and reduce the risk of pregnancy through family planning.

Abstract
There is a growing emphasis to use a transdisciplinary team approach to accelerate innovations in science to solve complex conditions associated with aging. However, the optimal organizational structure and process for how to accomplish transdisciplinary team science is unclear. In this forum, we illustrate our team's experience using transdisciplinary approaches to solve challenging and persistent problems for older adults living in urban communities. We describe our challenges and successes using the National Institutes of Health four-phase model of transdisciplinary team-based research. Using a de-identified survey, the team conducted an internal evaluation to identify features that created challenges including structural incongruities, inter-professional blind spots, group function, and group dynamics. This work resulted in the creation of the team's Transdisciplinary Conceptual Model. This model became essential to understanding the complex interplay between societal factors, community partners, and academic partners. Conducting internal evaluations of transdisciplinary team processes are integral for teams to move beyond the multi- and interdisciplinary niche and to reach true transdisciplinary success. More research is needed to develop measures that assess team transdisciplinary integration. Once the process of transdisciplinary integration can be reliably assessed, the next step would be to determine the impact of transdisciplinary team-science initiatives on aging communities.

Abstract
OBJECTIVE This study aimed at providing original data on fungemia in the Centre Hospitalier de Mayotte in terms of prevalence, epidemiological characteristics of infected patients, yeast species distribution and profile of in vitro antifungals susceptibility. METHODS A total of 223 positive blood cultures for yeasts were retrospectively reported during the period April 2010-April 2020. RESULTS Ninety-five episodes were identified corresponding to an incidence rate of 3.7 cases/100,000 inhabitants. The average age of patients was 33.5 years, and 63.3% patients were hospitalized in intensive care unit. The main co-morbidities were surgery in the 30 days prior to fungemia (27.8%), neoplasia (22.8%), parenteral nutrition (17.7%), diabetes (16.5%) and immunosuppressive medications (31.6%). Candida spp accounted for the majority of isolates (92.4%) with a predominance of non-albicans species (55.8% vs 33.7%), including C. albicans (33.7%), C. tropicalis (30.5%) and C. parapsilosis (20%). The antifungal susceptibility profiles did not differ from expected results for each species and did not change significantly over time. DISCUSSION Fungemia remain frequent hospital infections associated with high mortality in Mayotte. The vast majority of fungemia was due to Candida spp. Non-albicansCandida species reach half of the Candida isolates with a high percentage of C. tropicalis. Surprisingly, no case of candidemia due to C. glabrata were identified. The management of candidemia remains satisfactory and the treatment was adapted according to the international recommendations. However, the high susceptibility of Candida spp. isolates to fluconazole may invite to reconsider the use of this molecule as empirical and first-line treatment of candidemia in Mayotte.

Abstract
Older adults (i.e., 60 years and older), are the leading consumers of medications, and consequently are suffering the most from medication‐related adverse events. Not only are older adults the largest consumers of medications, they are more likely to experience an adverse drug event contributing to increased hospitalization, utilization of emergency medical services, and mortality. Translational Approaches to Personalized Health (TAPH) is a transdisciplinary team of researchers conducting community‐engaged participatory research focused on the discovery and translation of pharmacogenomic (PGx) data to improve health outcomes. Underserved and ethnically diverse older adults living in urban settings are significantly under‐represented in PGx studies. To address the issue of under‐representation, our study enrolls older African American adults into a community‐based PGx study. Therefore, we will characterize the frequency of actionable PGx genotypes and identify novel PGx response genes in our cohort of older community dwelling African Americans. The translational component of our work is to use the PGx findings to improve therapeutic outcomes for medication management in older adults. Such findings will serve as a foundation for translational PGx studies aimed at improving medication efficacy and safety for older adults. In this article, we describe the process for launching the TAPH collaborative group, which includes the transdisciplinary team, community‐engaged participatory research model, study measures, and the evaluation of PGx genes.

Abstract
Monolithic, millimeter-wave "system-on-chip" (SoC) technology has been employed in heterodyne receiver integrated circuit radiometers in a newly developed Electron Cyclotron Emission Imaging (ECEI) system on the DIII-D tokamak for 2D electron temperature profile and fluctuation evolution diagnostics. A prototype module operating in the E-band (72 GHz-80 GHz) was first employed in a 2 × 10 element array that demonstrated significant improvements over the previous quasi-optical Schottky diode mixer arrays during the 2018 operational campaign of the DIII-D tokamak. For compatibility with International Thermonuclear Experimental Reactor relevant scenarios on DIII-D, the SoC ECEI system was upgraded with 20 horn-waveguide receiver modules. Each individual module contains a University of California Davis designed W-band (75 GHz-110 GHz) receiver die that integrates a broadband low noise amplifier, a double balanced down-converting mixer, and a ×4 multiplier on the local oscillator (LO) chain. A ×2 multiplier and two IF amplifiers are packaged and selected to further boost the signal strength and downconvert the signal frequency. The upgraded W-band array exhibits >30 dB additional gain and 20× improvement in noise temperature compared with the previous Schottky diode radio frequency mixer input systems; an internal 8 times multiplier chain is used to bring down the LO frequency below 12 GHz, thereby obviating the need for a large aperture for quasi-optical LO coupling and replacing it with coaxial connectors. Horn-waveguide shielding housing avoids out-of-band noise interference on each individual module. The upgraded ECEI system plays an important role for absolute electron temperature evolution and fluctuation measurements for edge and core region transport physics studies.

Abstract
The Richmond Health and Wellness Program (RHWP) is an innovative interprofessional care coordination program that seeks to support the health and wellness of independent-living older adults and educate future practitioners. Since 2012, RHWP has provided community-based interprofessional training to students at Virginia Commonwealth University. The sudden suspension of clinical and community-based training due to the COVID-19 pandemic created the need to transform the traditional ways students received clinical education and support the vulnerable communities served by RHWP. This paper describes RHWP's rapid transition to a hybrid telephone-based program with a virtual learning component for students which allowed RHWP to continue serving its participants and provide interprofessional training experiences. Since the transition, RHWP has served 111 participants through over 400 telephonic visits, and 12 nurse practitioner and pharmacy students completed clinical hours to fulfill graduation requirements. To meet the needs of learners, interprofessional education models can be adapted to changing circumstances posed by COVID-19.

Abstract
Cyst scar post circumcision of the stump of the prepuce is pathology of which we have not found any cases in the literature. The circumcision traditional is still practiced in our regions with its attendant complications, in particular, the high section, the whole or part of the gland, infections. The case we report concerns a patient 24 years of age, having a large cyst of 8cm diameter, evolving for the past 17 years. The patient has not informed his parents that when the desire to marry has become very pressing. The consultation was motivated by the psychological trauma, the discomfort and the pain caused by the infection, and the fistulisation. The treatment was surgical with bedroom suites. This observation underscores the importance of the knowledge of good surgical technique in order to minimize complications; it also sheds light on the taboo side of the pathologies the sphere uro-genitale.

Abstract
OBJECTIVE to compare aspects of the diastolic component of umbilical artery flow with fetal fate parameters. MATERIAL AND METHODS this was a prospective, cross-sectional study at the Kaolack Regional Hospital over 6 months including patients with an at-risk pregnancy and a gestational age greater than 20 SA. The aspect of umbilical artery flow, umbilical artery IR and cerebro-placental index were studied.We compared the velocity data with the rates of fetal suffering, low birth weight and perinatal mortality. The statistical analysis was done with EPI info software version 7, Excel 2010 and SPSS 20.0 with a p-value of less than 5%. RESULTS 46 patients were included with an average age of 24.54 years. The mean gestational age was 33.7 AS. The diastolic component of umbilical artery flow was null in 19.6%; reversed in 10.9%; decreased in 21.7% and normal in 47.8%. Confrontation with fetal fate parameters found a rate of 78.6% fetal suffering in the null or reversed diastolic components group compared to 34.4% in the non-zero diastolic components group. For low birth weight, this rate was 92.9% compared to 28.1%. The perinatal mortality rate was 64.2% compared to 12.5%. CONCLUSION The umbilical artery Doppler study plays a major role in the monitoring and obstetric management of high-risk pregnancies. Our results demonstrate the correlation between a diastolic component of the flow of the pathological umbilical artery and the adverse outcome of the pregnancy at risk.

Abstract
AIM The aim of this work was to evaluate the diagnostic performance of imaging examinations in the presence of acute non-traumatic abdominal pain. MATERIALS AND METHODS This was a prospective, cross-sectional and descriptive study over 6 months in the radiology and medical imaging department of the Kaolack Regional Hospital, including any patient received for acute non-traumatic abdominal pain with informed consent in whom the etiological diagnosis is supported by an imaging examination. We investigated the etiologies of acute abdominal pain and compared the imaging findings with surgical exploration. Our data were analyzed using SPSS 24.0 and Excel 2013 with a coefficient of significance of less than 5%. RESULTS 106 patients were enrolled. The mean age was 32 years and the gender-ratio was 1.52 in favour of women. Acute abdominal pain was diffuse in 25.5% of patients and localized in 74.5%, of which 18.9% were at right iliac fossa.Abdominal X-ray was performed alone in 4 patients (3.8%), ultrasound alone in 46 patients (43.3%) and abdominal CT scan in 34 patients (32%). CT was combined with ultrasound in 6 patients (5.7%) and with abdominal X-ray in 16 patients (15%). The initial clinical diagnosis was corrected in 49.1% of patients. The sensitivity of the imaging compared to the final diagnosis retained was 96.2%. CONCLUSION Imaging represents a turning point in the management of patients with acute non-traumatic abdominal pain by providing better diagnostic guidance and avoiding serious complications and unnecessary interventions.

Abstract
Background
Perinatal transmission of hepatitis B virus (HBV) constitutes an important risk in highly endemic countries including Senegal. Although the prevalence of chronic HBV infection is estimated at 11% in this country, specific data on women of childbearing age are sorely lacking. We described in this study the prevalence of the HBV antigen (HbsAg) in women of childbearing age in rural Senegal, as well as general knowledge on HBV and hepatitis B status awareness.

A cross-sectional study including HBV screening was conducted at home in the rural Niakhar area. Chronic HBV infection was determined through HBsAg detection using dried blood spots. Socio-demographic and behavioral data were collected through standardized face-to-face questionnaires. The analyzes included 368 women aged 15-49 (67% married; 65% with at least 1 child) enrolled from October 2018 to March 2019.
Results
Preliminary results show that 49 women (13%) had positive HBsAg. Only 68 women (18%) have already heard about HBV. Among them, 53% knew that there exists an HBV vaccine and 78%, 75% and 67% correctly answered that HBV can be transmitted through blood contact, childbirth and sexual intercourse, respectively.
Among the 233 (63%) women who had already given birth, 76% had attended at least 4 antenatal care sessions and 74% had given birth in a healthcare facility for their last pregnancy. However, only 1% reported to have already been screened for HBV. Main reasons reported for not having been screened were having never heard about this test (80%) and not having been offered screening during antenatal care sessions (10%).
Conclusions
General knowledge and awareness of HBV status are particularly low in women of childbearing age living in rural Senegal, despite high antenatal care sessions attendance. Given the high prevalence of chronic HBV infection found in this population, it is urgent to ensure systematic HVB screening and to provide adequate information to women during pregnancy.
Key messages
The prevalence of chronic HBV is high in women of childbearing age in Senegal. National recommendations for women attending antenatal care sessions should include HBV screening and counselling.

Abstract
Abstract
Background
Hepatitis B vaccination during childhood is key to reduce the prevalence of Hepatitis B virus (HBV) infection. In Senegal, a highly endemic country, the three-dose hepatitis B vaccine and the birth dose vaccine were introduced in the Expanded Programme on Immunization (EPI) in 2004 and 2016 respectively. This study aimed to determine chronic HBV infection prevalence, hepatitis B vaccination status and vaccine immunity among children in Senegal.
Methods
A cross-sectional study including HBV screening was conducted at home among children aged 6 months to 15 years (i.e. born after the introduction of the HBV vaccine in the EPI) in the rural zone of Niakhar. Dried Blood Spot (DBS) samples were collected for the detection of HBsAg, anti-HBc Ab and anti-HBs Ab using chemoluminescence. Vaccination status was assessed using information on vaccination cards. Detectable vaccine immunity was defined with an adjusted DBS threshold of DOI≥0.36 IU/mL (corresponding to 10 IU/mL in venous blood sampling).
Results
Between October and December 2018, 455 children were enrolled. Preliminary results show that 7/455 (1.5%) had been in contact with HBV (positive anti-HBc Ab) and 5/455 (1.1%) had chronic HBV infection (positive HBsAg).
Only 161/455 (35.4%) children had a vaccination card available. Among those, 150/161 (93.2%) received at least 3 doses of hepatitis B vaccine, of which 83/150 (55.3%) had detectable vaccine immunity. The proportion of children with detectable vaccine immunity was significantly higher in children <5 years than in children aged 5-9 and 10-15 (72.3% versus 47.3%, p = 0.006 and 72.3% versus 14.3%, p < 0.001).
Conclusions
Preliminary results suggest a low prevalence of HBV chronic infection among children born after the introduction of HBV vaccination in Senegal. However, detectable vaccine immunity rapidly decreases with age among vaccinated children, signalling a need for further studies on the immune response to HBV vaccination in this context.
Key messages
HBV chronic infection is low among children born after the introduction of HBV vaccination in Senegal. Further studies on the immune response to HBV vaccination in this context are needed.

Abstract
Abstract
Introduction
Friedreich ataxia (FRDA) is a rare genetic sensory ataxia. The causal mutation is an expanded trinucleotide repeat (GAA) in the frataxin gene. Hypertrophic cardiomyopathy is associated with FRDA and is the major cause of early death before 40 years old. Patients with progressive decline of the left ventricular ejection fraction (LVEF) have the worse prognosis. Speckle tracking echography with 2D longitudinal myocardial strain (GLS) is recognized as a more effective technique than conventional LVEF in detecting subtle changes in LV function.
Purpose
Evaluate the prognostic value of global longitudinal strain (GLS) in patients with FRDA as compared to LVEF.
Methods
From 2003 to 2017 consecutive patients with genetically confirmed FRDA were included. Longitudinal strain analysis was retrospectively performed with Tomtec software. News were obtained until April 2018, no patient was lost during follow-up.
Results
The study included 156 patients (51% male) of 35±12 years (mean ± SD) with an age at disease onset of 17±11 years, age at wheelchair use of 26±10 years, and GAA repeat on the shorter allele of 590±241 pb. The following echocardiographic parameters were studied at baseline: LVEF 64±9%, GLS −19.8±5% (n=141), septal wall thickness (SWT) 11.4±2.5 mm, posterior wall thickness (PWT) 10.4±1.8 mm, LV end diastolic diameter (LVEDD) 44.4±6mm. Correlation between GLS and LVEF was 0.31 (p=0.0002).
After a mean follow-up of 7.7±4.0 years, 17 (11%) patients died and the outcome (cardiac arrhythmia, heart failure, stroke or death) concerned 28 (18%) patients. In univariate analysis (Cox model), factors associated with mortality were: GLS (HR: 1.2; 95% CI 1.10–1.32, p=0.0001), LVEF (HR: 0.88; 95% CI 0.85–0.92, p<0.0001), GAA (HR: 1.28; 95% CI 1.11–1.47, p=0.0008), age at onset (HR: 0.84; 95% CI 0.76–0.94, p=0.002), LVMi (HR: 1.02; 95% CI 1.01–1.04, p=0.0078), SWT (HR: 1.18 95% CI 1.01–1.36, p=0.03) and LVEDD (HR: 1.09; 95% CI 1.00–1.19, p=0.04). In multivariate analysis LVEF was the only independent predictor of long-term mortality (HR: 0.93; 95% CI 0.88; 0.99, p=0.02). Similarly GLS was not an independent predictor of the composite outcome in multivariate analysis.
Conclusion
GLS is a predictor of morbimortality but is not superior to LVEF in FRDA patients. Further prospective studies are mandatory to assess the early predictive value of 2D GLS.

Abstract
MOTIVATION Visualization of multiple genomic data generally requires the use of public or commercially hosted browsers. Flexible visualization of chromatin interaction data as genomic features and network components offer informative insights to gene expression. An open source application for visualizing HiC and chromatin conformation-based data as 2D-arcs accompanied by interactive network analyses is valuable. RESULTS DNA Rchitect is a new tool created to visualize HiC and chromatin conformation-based contacts at high (Kb) and low (Mb) genomic resolutions. The user can upload their pre-filtered HiC experiment in bedpe format to the DNA Rchitect web app that we have hosted or to a version they themselves have deployed. Using DNA Rchitect, the uploaded data allows the user to visualize different interactions of their sample, perform simple network analyses, while also offering visualization of other genomic data types. The user can then download their results for additional network functionality offered in network based programs such as Cytoscape. AVAILABILITY AND IMPLEMENTATION DNA Rchitect is freely available both as a web application written primarily in R available at http://shiny.immgen.org/DNARchitect/ and as an open source released under an MIT license at: https://github.com/alosdiallo/DNA_Rchitect.

Abstract
Canine papillomatosis is mainly attributed to papillomavirus infections. Papillomavirus DNA is also frequently identified in healthy skin, and evidence of high papillomavirus diversity complicates this simplistic view of causality. The aim of this study was to determine how frequently canine papillomas contain papillomavirus DNA and express viral protein, and how these factors correlate to the histology and anatomic location. Fifty-three archived, formalin-fixed samples of canine papillomas and eight samples of other proliferative skin lesions from dogs were included. Samples were re-evaluated histologically, tested for papillomavirus L1-antigen using immunohistochemistry, and for papillomavirus DNA with PCR assays and molecular sequencing. Most papillomas from haired skin contained papillomavirus DNA (96%) and antigen (92%). Of oral papillomas, 88% were positive for both papillomavirus DNA and antigen. Approximately 50% of non-papilloma proliferations and papillomas from eyelid/conjunctiva specimens contained viral DNA, but antigen was present in only 12% of eyelid/conjunctiva papillomas and in none of the non-papilloma proliferations. The presence of viral antigen was highly correlated with histological indicators of viral infection, including intranuclear inclusions, koilocytes, cytoplasmatic vacuolation and dysplasia. The viruses found were mainly CPV1 and CPV2. CPV1 dominated in oral infections, while CPV2 dominated in cutaneous endophytic papillomas. Co-infections with CPV1 and CPV2 accounted for about 20% of all detected infections. These results support a role for papillomaviruses in canine cutaneous and oral, exophytic and endophytic papillomas and support previously raised doubts about their role in squamous papillomas from eyelid/conjunctiva specimens.

Abstract
A detailed description of a prototype setup for real-time (RT) Thomson scattering (TS) analysis is presented and implemented in the multi-point Thomson scattering (MPTS) diagnostic system at the National Spherical Torus Experiment Upgrade (NSTX-U). The data acquisition hardware was upgraded with RT capable electronics (RT-analog digital converters and a RT server) that allow for fast digitization of the laser pulse signal of eight radial MPTS channels. In addition, a new TS spectrum analysis software for a rapid calculation of electron temperature (Te) and electron density (ne) was developed. Testing of the RT hardware and data analysis software was successfully completed and benchmarked against the standard, post-shot evaluation. Timing tests were performed showing that the end-to-end processing time was reproducibly below 17 ms for the duration of at least 5 s, meeting a 60 Hz deadline by the laser pulse repetition rate over the length of a NSTX-U discharge. The presented RT framework is designed to be scalable in system size, i.e., incorporation of additional radial channels by solely adding additional RT capable hardware. Furthermore, it is scalable in its operation duration and was continuously running for up to 30 min, making it an attractive solution for machines with long discharges such as advanced, non-inductive tokamaks or stellarators.
