Background
The efficacy and cost-effectiveness of prophylactic thrombolytic locks in hemodialysis patients at high-risk of thrombotic dialysis catheter dysfunction is uncertain. We investigated this question in a double-blinded randomized controlled study.

Methods
Prevalent hemodialysis patients from 8 Belgian hemodialysis units, with ≥2 separate episodes of thrombotic dysfunction of their tunneled cuffed catheter during the 6 months before inclusion, were randomized to either: taurolidine heparin locks thrice weekly (control arm) or the same locks twice a week combined with taurolidine urokinase locks once a week before the longest interval without HD (TaurolockU arm). The primary efficacy outcome was the incidence rate of catheter thrombotic dysfunction requiring thrombolytic locks to restore function.

Results
68 hemodialysis patients (32 controls, 36 urokinase) were followed during 9875 catheter days between May 2015 and June 2017. Incidence rate of thrombotic catheter dysfunction was 4.8 in TaurolockU vs 12.1/1000 catheter days in control group (rate ratio 0.39; 95%CI 0.23–0.64). 15/36 (42%) catheters in the treatment group required at least one therapeutic urokinase lock vs 23/32 (72%) in the control group (P = 0.012). The two groups did not differ significantly in catheter-related bloodstream infection and combined cost of prophylactic and therapeutic catheter locks. The TaurolockU group had a numerically higher number of episodes of refractory thrombosis.

Conclusions
Prophylactic use of urokinase locks is highly effective in reducing the number of thrombotic catheter dysfunctions in catheters with a history of recurring dysfunction. Prophylactic use of urokinase locks did not reduce the overall costs associated with catheter locks and was associated with a numerically higher number of episodes of refractory thrombosis.

BackgroundNature relatedness can be associated with health-related outcomes. This study aims to evaluate the associations of nature relatedness with physical activity and sedentary behavior.MethodsA cross-sectional study involving 9–12 year old children living in Cuenca, Ecuador, was conducted between October 2018 and March 2019. Questionnaires were used to evaluate physical activity (PAQ-C), out-of-school sedentary behavior, nature relatedness and wellbeing. Associations of nature relatedness with physical activity, and sedentary behavior were evaluated using linear regression models or tobit regressions adjusted by age, sex, school type, wellbeing, and body mass index z-score.ResultsA total of 1028 children were surveyed (average age:10.4±1.22 years, 52% female.). Nature relatedness was positively associated with physical activity (β = 0.07; CI 95%: 0.05–0.09; p < 0.001) and non-screen-related sedentary leisure (β = 3.77 minutes; CI 95%: 0.76–6.68; p < 0.05); it was negatively associated with screen time (β = -5.59 minutes; CI 95%: -10.53–0.65; p < 0.05).ConclusionsFindings suggest that nature relatedness is associated with physical activity and some sedentary behaviors among Ecuadorian school-age children. The promotion of nature relatedness has the potential to improve health.

Published: May 2021

Background
Predicting waiting time for a deceased donor kidney transplant can help patients and clinicians to discuss management and contribute to a more efficient use of resources. This study aimed at developing a predictor model to estimate time on a kidney transplant waiting list using a machine learning approach.

Methods
A retrospective cohort study including data of patients registered, between January 1, 2000 and December 31, 2017, in the waiting list of São Paulo State Organ Allocation System (SP-OAS) /Brazil. Data were randomly divided into two groups: 75% for training and 25% for testing. A Cox regression model was fitted with deceased donor transplant as the outcome. Sensitivity analyses were performed using different Cox models. Cox hazard ratios were used to develop the risk-prediction equations.

Results
Of 54,055 records retrieved, 48,153 registries were included in the final analysis. During the study period, approximately 1/3 of the patients were transplanted with a deceased donor. The major characteristics associated with changes in the likelihood of transplantation were age, subregion, cPRA, and frequency of HLA-DR, -B and -A. The model developed was able to predict waiting time with good agreement in internal validation (c-index = 0.70).

Conclusion
The kidney transplant waiting time calculator developed shows good predictive performance and provides information that may be valuable in assisting candidates and their providers. Moreover, it can significantly improve the use of economic resources and the management of patient care before transplant.
Effects of ultra-dry storage on seed germination and seedling growth of <i>Handeliondendron bodinieri</i>

Published: May 2021

(H. LÃ©v.) Rehder is a rare, endangered, and therefore, protected tree species native to China. However, there are serious limitations to the effective protection of the species, including a low seed germination-rate and difficult storage due to a high seed oil-content. Here, we evaluated the feasibility of ultra-dry seed storage and its effects on seedling growth. We used the silica gel method to prepare ultra-dry seeds with different moisture contents to find an optimal moisture content range (2.54%â4.77%). Ultra-dry treatment improved storability of . Furthermore, seeds with a moisture content of 4.77% stored at room temperature, and seeds with a moisture content of 3.97% stored at 4 Â°C yielded the best results. Priming with an appropriate concentration of polyethylene glycol had a certain repairing effect on ultra-dry stored seeds and improved seed vigor, with a two-day priming treatment with 20% polyethylene glycol having the best effect. Finally, compared with sand storage at 4 Â°C, ultra-dry storage promoted seedling growth and root development; furthermore, it alleviated storage damage to seeds, promoted soluble sugar and soluble protein accumulation, and increased seedling nitrogen, phosphorus, and potassium uptake. Therefore, ultra-dry storage can be effectively used to preserve seeds. Specifically, low-temperature storage of ultra-dry seeds with a moisture content of 3.97% enhanced seed vigor, and seedling growth and development.Handeliodendron bodinieriH. bodinieri seedsH. bodinieriH. bodinieriH. bodinieri

New Musicians and Travelers in Cuba
Authors: Storhoff Timothy P. 
Published: May 2021

This chapter focuses on why musicians want to visit Cuba, how social networks help them get there, and how the influx of new visitors impacted US-Cuban musical relations. An analysis of the social network that has brought a group of Minnesota musicians to the Cubadisco Festival in 2013 and the Minnesota Orchestra there in 2015 shows how Obama-era policies spawned and strengthened transnational musical networks. Both US and Cuban musicians drew upon some amount of previously-accumulated social capital or other human resources available to them in order to navigate the complicated bureaucracies that govern travel across the Florida Straits. Through participation in musical exchanges they blurred the lines between pilgrimage, tourism, and purposeful travel.
Intro: The Meanings of a Musical Style
Authors: Rapport Evan 
Published: May 2021

Punk is an extraordinarily meaningful and productive set of musical approaches, and exploring punk rock’s history based on an analysis of its musical style leads to conclusions that are often in conflict with the stories that have been told. This chapter establishes several premises that are investigated in the rest of the book, including punk’s complicated relationship to American whiteness and the suburbs, and punk’s underappreciated basis in African American musical resources.
“Less Art and More Machine”: The California Crucible
Authors: Rapport Evan 
Published: May 2021

Early American punk had its most explicit identity crisis in Los Angeles during the late 1970s, and the sounds created in California during this time, including San Francisco, effectively defined American punk moving forward. Punk in Los Angeles in particular reflected some of the most extreme changes of the post-war era, with substantial migration, new development, and geographic segregation. California became the major site for debates over the meaning of punk styles, with growing tensions between older punks in the downtown or “Hollywood” scene, such as X and the Screamers, and the younger punks in suburban and beach areas, such as Circle Jerks and Black Flag, and ultimately, the style of suburban hardcore punk that was forged in California came to define punk for American listeners. It was in California where punk morphed from an expression of the sixties generation into a voice for Generation X heading into the 1980s. This chapter also takes a close look at punk’s relationship to violence, especially with respect to the confrontations between punks and the LAPD. The musical life of Latinx punks (and Chicano or Mexican American punks specifically) serves as a case study for further investigations of social and musical complexities in Los Angeles.
Afterword
Authors: Gentry Marshall Bruce 
Published: May 2021

Bruce Gentry, the editor of Flannery O’Connor Review, reflects on the state of O’Connor studies. He shares the story of why and how the National Endowment for the Humanities Institutes on O’Connor came about, reviews a few of the struggles and successes, and shares a few thoughts about the future of O’Connor scholarship. He argues that while he no longer thinks we will ever fully figure out O’Connor as a Catholic writer, he believes O’Connor wanted to be taken seriously, first and foremost, as a writer, and, therefore, he has defined his mission as working to expand O’Connor studies beyond the southern and beyond the Catholic. He then discusses O’Connor’s broad appeal in disciplines beyond English. He celebrates the increasing diversity in approaches to her work and anticipates that the trend will continue as we find new answers to old questions and answers to brand new questions too.
Changes in the antioxidative properties of honeys during their fermentation
Authors: Głód Bronisław K. , Piszcz Paweł 
Published: May 2021

Abstract
The aim of this preliminary study was to investigate whether the fermentation process affects the antioxidative properties of honeys. Therefore, the total antioxidant potential (TAP) of eleven meads was examined. TAPs were estimated using DPPH, hydroxyl radicals, and amperometric measurements in the flow-through HPLC system. The results were correlated with the total content of polyphenols and anthocyanins. Additionally, the concentrations of ethanol, sugars, and hydrogen peroxide were measured. The influence of side reactions and the presence of hydrogen peroxide, glucose, ethanol, and anthocyanins on the free radicals generation were also tested. The use of HPLC electrochemical detection for TAP measurements is particularly preferred. Depending on the potential used, different antioxidants can be measured. It turned out that fruit and species meads are characterized by much higher TAPs measured at high potential of the working electrode than at lower potential due to the high concentration of weak antioxidants which do not provide signals at low potentials. It was found that dark honeys (buckwheat, honeydew) are characterized by much higher TAP values than light ones (acacia, linden, multi-floral). The concentration of anthocyanins decreased during fermentation. They are removed together with the sediment.
Mito y memoria histórica en Los recuerdos del porvenir de Elena Garro
Authors: Junco Ethel 
Published: May 2021

Resumen

Los recuerdos del porvenir remeda el período postrevolucionario mexicano desde un pueblo marginal y militarizado; la novela está articulada por mujeres de aspecto normal y de interioridad inescrutable. Garro expone su visión crítica de la historia a través de la radicalización de lo femenino mediante el personaje de Julia, construido sobre el modelo de Helena de Troya, como simbolización de la energía incontrolable de Afrodita. Una hermenéutica sustentada en paradigmas míticos apoya la lectura de los tópicos de la autora —género, poder político, discriminación, solidaridad— y amplía la difícil comprensión del fenómeno de base, brindando un acceso a la irracionalidad de los procesos históricos.
Multidirectional Memory, Polyacroasis and (Un)translatability in Antonio Muñoz Molina’s Sefarad
Authors: Amezcua David 
Published: May 2021

Abstract
The primary aim of this chapter is to analyse the alignment between multidirectional memory and literature. Michael Rothberg’s multidirectional memory model is scrutinized so as to elucidate how this approach works in fiction. The chapter further analyses the rhetorical concept of polyacroasis, proposed by Tomás Albaladejo in 1998 in order to analyse its interlacing with multidirectional memory as well as to demonstrate the manner in which polyacroasis may function as a vehicle of multidirectional memory in literature. On the other hand, the notion of translator as secondary witness (Deane-Cox, 2013; 2017) will be employed so as to examine the role of the author as translator. By means of a case study, Antonio Muñoz Molina’s Sefarad. Una novela de novelas, I will attempt to analyse how the frameworks provided by multidirectional memory and polyacroasis along with the workings of empathy encourage and pave the way to translatability. Similarly, I will examine how the notion of translator as secondary witness functions in a novel like Sefarad taking into account that the author of that novel inscribed his translation into Spanish of passages coming from Holocaust testimonies which were not published in Spain by the time the novel was being written.
Ansorge’s cusimanse in Angola: 100 years apart, new records contribute to the species known range
Authors: Elizalde Castells David , Elizalde Sara R. F. F. , Ceríaco Luis M. P. , Groom Rosemary Joy 
Published: May 2021

Abstract
Ansorge’s cusimanse, Crossarchus ansorgei Thomas, 1910, has until recently been known in Angola only from a single specimen collected in 1908, the holotype. During a camera trap survey conducted in Quiçama National Park (Angola) in 2017, we recorded the presence of the species 115 km south-west of the type locality – 40 km from the edge of the current known distribution range, – extending it south of the Cuanza river and possibly following the woodlands along the Angolan Escarpment. We combine our records of Ansorge’s cusimanse with the available published and unpublished records from Angola and compare with other vertebrate taxa that follow a similar pattern, in which Central African species extend their southern distribution into Angola, through the more forested areas in northwestern Angola and further south along the Escarpment. Furthermore, we discuss the urgent need for more research on this species and the impact bushmeat harvesting may have on its conservation.

A review of current physical techniques for dispersion of cellulose nanomaterials in polymer matrices
Authors: Chanda Saptaparni , Bajwa Dilpreet S. 
Published: May 2021

Abstract
Cellulose nanomaterials (CNMs) naturally exist in biomass. Recent developments in nanotechnology and extraction procedure of CNMs open up a new era in the polymer composites industry. Abundant, renewable, biodegradable, transparent, light weight, and most importantly, low cost make CNMs the ideal material for packaging, automotive, construction, and infrastructure applications. CNMs are generally used as materials for polymer matrix reinforcement in the composites industry. The industrial-scale manufacturing of CNM/thermoplastic composites remains an unsolved puzzle for both academics and industries. The dispersion of nanocellulose in polymer matrix is the central problem inhibiting the manufacturing of CNM/polymer composites at an industrial scale. Several attempts were made to disperse nanocellulose effectively in a polymer matrix and improve compatibility between the matrix and CNMs. Chemical-aided surface modification of CNMs has been effective in several cases; however, chemical toxicity, high price, and critical control of reactions make them unsuitable. This current review paper focuses on novel eco-friendly physical dispersion techniques of CNMs and their future scope of research. The physical dispersion techniques such as plasma-induced surface modification, ultrasonication, magnetic and electric field discharge, electrospinning, or drawing can visibly improve the dispersion state of CNMs. But several factors affect physical techniques’ performance, e.g. CNM type and forms, process conditions and parameters, etc. Moreover, the material-related factors interplay with the process-related factors. This review addresses the current state of knowledge on the physical dispersion techniques for CNMs and identifies challenges that are critical to adoption of these novel materials at commercial scale for future applications.
