Abstract
We report on the host association of FRB 20181030A, a repeating fast radio burst (FRB) with a low dispersion measure (103.5 pc cm−3) discovered by the CHIME/FRB Collaboration et al. Using baseband voltage data saved for its repeat bursts, we localize the FRB to a sky area of 5.3 arcmin2 (90% confidence). Within the FRB localization region, we identify NGC 3252 as the most promising host with an estimated chance-coincidence probability <2.5 × 10−3. Moreover, we do not find any other galaxy with M

r
< −15 AB mag within the localization region to the maximum estimated FRB redshift of 0.05. This rules out a dwarf host 5 times less luminous than any FRB host discovered to date. NGC 3252 is a star-forming spiral galaxy and at a distance of ≈20 Mpc, it is one of the closest FRB hosts discovered thus far. From our archival radio data search, we estimate a 3σ upper limit on the luminosity of a persistent compact radio source (source size < 0.3 kpc at 20 Mpc) at 3 GHz to be 2 × 1026 erg s−1 Hz−1, at least 1500 times smaller than that of the FRB 20121102A persistent radio source. We also argue that a population of young millisecond magnetars alone cannot explain the observed volumetric rate of repeating FRBs. Finally, FRB 20181030A is a promising source for constraining FRB emission models due to its proximity and we strongly encourage its multi-wavelength follow-up.

Published: October 2021

Biologically active substances, the antioxidant and antimicrobial activity of aqueous, 70% ethylate and ethyl acetate extracts of fruits of maclura orange (Osage Orange), a representative of the Moraceae genus growing in the Ararat region of Armenia have been studied. It is found that plant extracts are rich in a wide range of pharmacologically active substances, in particular, tannins, flavonoids, organic acids, vitamins, anthocyanins, micro- and microelements, etc.
Based on the investigations performed, extracts of maclura orange can be recommended as a source of biologically active substances (BAS), as well as a preventive and corrective agent in deficiency or imbalance of macro- and microelements in tissue and cellular structures in various pathological processes in the body.
An ethanol extract of maclura fruits exhibits the antimicrobial activity against Bacillus subtilis 1820, E. Coli 5002, Serratia marcescens 5251 and Staphylococcus aureus ATCC-6538 strains. Maclura extracts can be used as an environmentally friendly source of antioxidants against early aging.
Long term changes of the inner-alpine steppe vegetation: the dry grassland communities of the Vinschgau (South Tyrol, Italy) 40–50 years after the first vegetation mapping
Authors: Lübben Maximilian , Erschbamer Brigitta 
Published: October 2021

Aims: The Vinschgau is the driest inner-alpine valley in the Eastern Alps and harbours a unique steppe vegetation. We studied these dry grassland communities and aimed to answer the following questions: Which plant communities can be found currently? Do the syntaxa described by Braun-Blanquet in the 1960s still prevail in the area? Has there been any change in species composition over the last 40–50 years?Study area: Along an approximately 40 km transect, the south-facing slopes of the Vinschgau valley (South Tyrol, Italy) from Mals to Plaus were investigated.Methods: For the classification, 92 relevés were sampled in 2019 and compared with 76 relevés from the 1960s and ´70s by means of vegetation tables and ordinations (Detrended Correspondence Analysis).Results: Based on our investigation, the majority of dry grassland communities can be classified asFestuco-Caricetum supinae. Three subassociations were defined by the dominant speciesStipa capillata,Bothriochloa ischaemumandStipa pennataagg. The comparison of new and old relevés shows an increase in species from the classSedo-Scleranthetea(e.g.Trifolium arvense,Erodium cicutarium) and the associationArtemisieto-Agropyretum. In addition, ruderal elements (e.g.Erigeron annuus,Convolvulus arvensis) have also migrated into dry grasslands. A shift in the dominance over time can be recognized as well. In particular,Festuca rupicolaand to some extent alsoStipa capillata, have increased in abundance and frequency.Conclusions: We suggest to include the investigated closed dry grasslands in the allianceFestucion valesiacae. The rank of the character species at association, alliance and order level should be re-analysed. In order to obtain a better syntaxonomic overview of western and eastern alpine dry grassland communities in relation to Eastern European dry grasslands, a comprehensive study is absolutely necessary. Furthermore, long-term vegetation dynamics and vegetation change need to be studied in more detailed future studies.Taxonomic reference: Fischer et al. (2008).Syntaxonomic references: Mucina et al. (2016) for syntaxa from alliance to class level; Braun-Blanquet (1961) for associations.Abbreviations: agg. = aggregate; cf. = confer (means ‘compare’); DCA = Detrended Correspondence Analysis; s. lat. = sensu lato; s. str. = sensu stricto

Authors: Rosenbaum James T. , Weisman Michael H. , Hamilton Hedley , Shafer Cassie , Aslanyan Elin , Howard Richard A. , Ogle Kimberly , Reveille John D. , Winthrop Kevin L. , Choi Dongseok 
Published: October 2021

ObjectiveThe coronavirus disease 2019 (COVID-19) pandemic has created multiple uncertainties regarding rheumatic diseases or their treatment, with regard to the susceptibility to or severity of the viral disease. We aimed to address these questions as they relate to spondyloarthritis (SpA).MethodsWe created a longitudinal survey from April 10, 2020, to April 26, 2021. There were 4723 subjects with SpA and 450 household contacts who participated worldwide. Of these, 3064 respondents were from the US and 70.4% of them provided longitudinal data. To control for the duration of potential risk of COVID-19, the rate of contracting the disease was normalized for person-months of exposure.ResultsIn an analysis of US subjects who provided longitudinal data, the incident rate ratio for the 159 (out of 2157) subjects who tested positive for COVID-19 was 1.16 compared to the US population as adjusted for age and sex (range 0.997–1.361, P = 0.06). A paired evaluation using patients and household members did not show a statistically significant effect to indicate a predisposition for developing COVID-19 as a result of SpA or its treatment. Our data failed to show that any class of medication commonly used to treat SpA significantly affected the risk of developing COVID-19 or increasing the severity of COVID-19.ConclusionThese data do not exclude a small increased risk of developing COVID-19 as a result of SpA, but the risk, if it exists, is low and not consistently demonstrated. The data should provide reassurance to patients and to rheumatologists about the risk that COVID-19 poses to patients with SpA.
Refractive Error Profile of Preterm Infants at 1-Year Follow-up in a Tertiary Care Hospital
Authors: Arora Priyanka , Arora Kamaldeep , Utaal Shubhneek Kaur Dhillon , Bansal Namita 
Published: October 2021

Purpose:
To study the refractive outcome in preterm infants with and without retinopathy of prematurity (ROP) in a tertiary care hospital in North India.

Methods:
This prospective study was conducted on 300 consecutive premature infants with a birth weight of 2 kg or less and a gestational age of 34 weeks or less at birth. The infants were divided into three groups (no ROP, spontaneously regressed ROP, and laser-treated ROP) and were followed up at 1 year of age to assess the presence and type of refractive error in each group.

Results:

The refractive error data were available for 277 neonates (554 eyes). On cycloplegic retinoscopy at 1 year of follow-up, the incidence of myopia was 12.29%, 29.55%, and 48.83% in all three groups, respectively, being most common in the laser-treated group, and the values were statistically significant (
P
< .05). Moreover, high myopia was most prevalent in the laser-treated group (23.25%). A correlation between birth weight and gestational age with spherical equivalent showed that a low birth weight and a low gestational age are more commonly found in infants with a more negative spherical equivalent.

Conclusions:
Infants with laser-treated ROP have a higher incidence of myopia than those with spontaneously regressed ROP or no ROP.

Publication Rate of Abstracts Presented at AAPOS Annual Meetings: From Conference Abstract to Full-Text Article
Authors: Vagge Aldo , Roda Matilde , Nucci Paolo , Siccardi Gabriele , Agrusta Marina , Catti Carlo , Cannavacciuolo Tommaso , Giannaccare Giuseppe , Traverso Carlo Enrico 
Published: October 2021

Purpose:
To review and analyze abstracts presented at American Association for Pediatric Ophthalmology and Strabismus (AAPOS) annual meetings, and to identify publication rates and potential predictive factors for better outcomes.

Methods:
All abstracts accepted for presentation at AAPOS annual meetings from 2013 to 2017 were examined. A comprehensive literature search via PubMed and Scopus was conducted to identify whether the abstracts had been published as full text. A multivariate analysis was achieved to assess the factors related to successful publication, and a Kaplan-Meier analysis was performed to evaluate the publication time course of abstracts.

Results:

Of 819 analyzed abstracts, 437 (53%) were published in peer-reviewed journals with a median impact factor of 2.7. The overall mean time to publication was 3 ± 2.2 years. The multivariate analysis revealed that abstracts were more likely to be published if they were accepted at an AAPOS annual meeting as an oral paper (
P
< .001), if they were prospective (
P
> .001) and multicenter (
P
= .013) studies, and if they had strabismus, retina, and vitreous disorders and diagnosis as main topics (
P
= .022). The Kaplan-Meier analyses revealed significant differences in the publication time distribution for multicenter versus single-center abstracts and paper versus poster and e-poster (
P
< .05).

Conclusions:
More than half of the abstracts accepted for presentation at the AAPOS annual meetings were published in peer-reviewed journals within 3 years from submission to the meeting. The factors associated with a higher publication rate were the prospective study design, multicentricity, and presentation at the meeting as an oral paper.

Authors: Prendergast Erica , Allen Kiona Y. , Mills Michele Grimason , Moran Thomas , Harris Z. Leah , Malakooti Marcelo , Smith Craig M. , Wainwright Mark S. , McCarthy-Kowols Maureen 
Published: October 2021

Background
In patients with acute neurological injury, abrupt temperature change exacerbates increased intracranial pressures and negatively affects perfusion pressure and cerebral blood flow. Critical care nurses must provide coordinated and effective interventions to maintain normothermia without precipitating shivering immediately after acute neurological injury in pediatric patients.

Objective
To improve hyperthermia management in a 40-bed pediatric intensive care unit, an interdisciplinary pediatric critical care team developed, implemented, and evaluated a targeted temperature management protocol.

Methods
The project was guided by the organization’s plan-do-study-act quality improvement process. Quality improvement was assessed retrospectively using electronic medical records of patients meeting eligibility criteria. Samples of pediatric patients who received temperature interventions were compared before and after protocol implementation. The protocol included environmental, pharmacological, and body surface cooling device interventions, as well as use of a bedside shivering assessment scale and stepwise interventions to prevent and control shivering.

Results
Before implementation of the targeted temperature management protocol, 64% of patients had documented temperatures higher than 37.5 °C, and body surface cooling devices were used in 10% of patients. After protocol implementation, more than 80% of patients had documented temperatures higher than 37.5 °C, and body surface cooling devices were used in 62% of patients. Four patients (6%) before and 5 patients (31%) after protocol implementation were treated with body surface cooling without requiring use of neuromuscular blockade.

Conclusions
Creation and implementation of a targeted temperature management protocol increased nurses’ documented use of body surface cooling to manage hyperthermia in pediatric intensive care unit patients with acute neurological injury.
Single ileal segment in a cat-tail configuration for bilateral ureteric strictures
Authors: Singh Abhishek , Parikh Deval , Surwase Pavan Prabhakar , Agrawal Shashank , Ganpule Arvind , Sabnis R. B. , Desai M. R. 
Published: September 2021

Introduction:
Management of bilateral long length ureteric strictures is difficult with few options for reconstruction. In this report, we describe our experience with the use of a single, 15- 20 cm ileal segment for reconstruction of bilateral long length (involving more than 2/3rd ureter) ureteric strictures.

Patients and Methods:
A retrospective analysis of 5 cases operated between 2015 and 2020for bilateral long length ureteric strictures, using a single segment ileal interposition in a cat tail configuration was performed. We evaluated renal function, surgical success, incidence of urinary tract infection and complications of the procedure. Surgical success was defined as an asymptomatic patient with no hydronephrosis and/or prompt drainage of the kidney on radiological investigations.

Results:
The average age of presentation was 42.8 ± 7.4 years (33-53) years). All the cases were secondary to a gynaecological intervention. The mean creatinine prior to surgery was 0.81 ± 0.36 mg % (range 0.5 -1.4 mg%). Mean duration of follow-up was 28.6 ± 20.6 months (Range 10 – 56 months). Mean hospital stay was 14.4 ± 3.36 days (range 12-20 days). Two patients developed ileus and one patient developed deep venous thrombosis in the post-operative period. One patient developed pyelonephritis within one month of surgery. There was no deterioration of renal function with the mean serum creatinine at last follow-up being 0.9 ± 0.36 mg% (range 0.6 – 1.5 mg%).

Conclusion:
The use of an ileal segment in cat-tail configuration for bilateral simultaneous ileal replacement is a feasible and safe option. The medium-term result states that it is effective in the preservation of renal function and provides a good conduit for drainage.
Assessing information on YouTube™ as a quality source for the treatment of varicoceles
Authors: Hong H. Stephen , Lang J. Jacob , Damodaran Shivashankar , Sindhwani Puneet 
Published: September 2021

Introduction:
YouTube™ has grown into one of the largest disseminators of health care information. We assessed the quality of information on varicoceles and their treatment, available on YouTube™.

Methods:
Using a YouTube™ search query with the keyword “varicocele,” the quality of the first 50, nonrepeat videos in English were assessed as a representative group for the topic. DISCERN and Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-AV) standardized tools were utilized by three independent reviewers to grade the quality of these videos based on content, understandability, and actionability.

Results:
The average and median DISCERN score was 31.34 (±9.37) and 31 (interquartile range 25–35), respectively, indicating poor quality. The interrater reliability (IRR) scores ranged from 0.51 to 0.93, indicating fair to excellent reliability. The average PEMAT-AV understandability and actionability scores were 69.8% ±15.4% and 11.0% ±24.6%, respectively, indicating mostly understandable but poor actionability. The t-test results showed that international videos scored higher without statistical significance in the DISCERN or PEMAT-AV scores (P = 0.18, 0.59, and 0.20).

Conclusions:
The current quality of videos on YouTube™ on the topic of varicoceles is of poor quality due to a lack of a holistic approach in explaining the wide range of treatment options available. With the ease of access to produce and disseminate health information, there is a need to create high-quality videos on varicoceles that empower a patient to make an informed decision.
The renewal of the digital humanities. An overview of the transformation of professions in the humanities and social sciences
Authors: Massot Marie-Laure , Tricoche Agnès 
Published: September 2021

This article presents a study of the French-speaking digital humanities. It is based on the experience of two research engineers from the French National Center for Scientific Research (CNRS) who have been studying these issues for the last ten years. They conducted a survey at the École Normale Supérieure (ENS-Paris) which enabled them to draw up an overview of the transformation of the profession of humanities and social sciences research engineers in the context of the digital humanities. The Digit_Hum initiative, which they run in parallel with their respective activities at the ENS, also provided information for this overview thanks to its role as a space for discussion about the digital humanities along with training and structuring of this field at the ENS and the Université Paris Sciences & Lettres (PSL).
Cet article est une réflexion sur les humanités numériques en contexte francophone. Elle s’appuie sur l'expérience de deux ingénieures du Centre National de la Recherche Scientifique travaillant sur ces questions depuis une dizaine d'années. À travers l'enquête qu'elles ont menée à l'École normale supérieure (ENS-Paris), elles dressent un panorama de la transformation du métier d'ingénieur(e) en sciences humaines et sociales dans le contexte des humanités numériques. L'initiative Digit_Hum, qu'elles animent en parallèle de leurs activités respectives à l'École, nourrit également ce témoignage en constituant un espace de discussions, de formations et de structuration des humanités numériques au sein de l'ENS et de l’Université Paris Sciences & Lettres.
El concepto de crisis y sus denominaciones: tipos y causas de las variaciones en la terminología de la crisis económica mundiao
Authors: Alves da Silva Manoel Messias , Zuluaga Molina Juan Felipe 
Published: October 2021

El objetivo de este articulo es presentar el concepto de crisis en el ámbito económico y sus denominaciones en portugués brasileño (PB) y español europeo (EE), por medio del estudio de sus variantes denominativas en ambas lenguas, a saber: crise económica, crise de 2008, grande crise e grande crise global; crisis económica, crisis de 2008, gran crisis y gran crisis de la globalización; respectivamente, todo esto con el fin de identificar los tipos y causas de estas variaciones. Estas variantes, retomando la descripción propuesta por Freixa (2014), presentan los siguientes tipos: variantes morfosintácticas, que son variaciones de carácter inferior al léxico, ya sea por el cambio en su estructura sintagmática o el mantenimiento o cambio del género o el número; o léxicas, que pueden considerarse como la sinonimia propiamente, ya que el cambio es total entre las dos unidades léxicas que tienen el mismo significado. Entre las causas propuestas por la misma autora (2014), solo se considerarán las siguientes: funcional, que tiene su origen en los diferentes registros comunicativos; y estilística, que está relacionada con las opciones y necesidades comunicativas de un autor. Los tipos y las causas de las variaciones se presentarán, ejemplificarán y analizarán, a partir de contextos recopilados en un corpus brasileño y un corpus español del proyecto Valores culturais e didácticos na metáfora de especialidade: as múltiplas imagens da crise económica mundial na imprensa escrita (Valores culturales y didácticos en la metáfora de especialidad: las múltiples imágenes de la crisis económica mundial en la prensa escrita), proyecto de investigación integrado que involucra a la niversidade de Sao Paulo, Unesp, UEM y a la Universidade de Vigo, con fondos de la CAPES (Coordenacao de aperfeicoamento de pessoal de nivel superior, Coordinación de Perfeccionamiento de Personal de Nivel Superior) / DGPU (Dirección General del Patrimonio Universitario). Se concluye que la búsqueda de variantes denominativas es importante para presentar una terminología in vivo ya que, en el caso específico del concepto de crisis y sus enominaciones, ya se han identificado variaciones que van mucho más allá del principio de univocidad.
Public R&D procurement: main factors of effectivness
Authors: Osipova E. V. , Smirnova T. G. 
Published: October 2021

The aim of the study is to analyze the existing problems in R&D procurement for the federal and municipal needs. The authors carried out a comparative analysis of the conducted surveys of the government customers and contractors representing research organizations and universities as well as of bidding documents and evaluation criteria for choosing the best offers in government procurement of social science research. The results of the study show that the currently applied approaches to the effectiveness evaluation of research organizations do not allow the selection of a duly qualified executor of a government order. A customer has to take decisions in conditions of high uncertainty both for the assessment of scientific capacity of a contractor and for the estimation of necessary resources to achieve the set goal. That makes the authors conclude that there is an urgent need in elaboration of alternative competitive criteria.
Sinister Resonance
Authors: Toop David 
Published: September 2021

Sinister Resonance begins with the premise that sound is a haunting, a ghost, a presence whose location is ambiguous and whose existence is transitory. The intangibility of sound is uncanny – a phenomenal presence in the head, at its point of source and all around. The close listener is like a medium who draws out substance from that which is not entirely there.
The history of listening must be constructed from the narratives of myth and fiction, ‘silent’ arts such as painting, the resonance of architecture, auditory artefacts and nature. In such contexts, sound often functions as a metaphor for mystical revelation, forbidden desires, formlessness, the unknown, and the unconscious. As if reading a map of hitherto unexplored territory, Sinister Resonance deciphers sounds and silences buried within the ghostly horrors of Arthur Machen, Shirley Jackson, Charles Dickens, M.R. James and Edgar Allen Poe, Dutch genre painting from Rembrandt to Vermeer, artists as diverse as Francis Bacon and Juan Munoz, and the writing of many modernist authors including Virginia Woolf, Samuel Beckett, and James Joyce.
