Abstract

Key Points

Frailty prevalence varies for the Frailty Phenotype, a frailty index, and the Clinical Frailty Scale in transplant candidates.Agreement between these measures for determining frailty status was variable, suggesting they measure different aspects of frailty.The frailty index and the Clinical Frailty Scale were associated with a shorter time to death or waitlist withdrawal in an unadjusted analysis.

Background
Comparisons between frailty assessment tools for waitlist candidates are a recognized priority area for kidney transplantation. We compared the prevalence of frailty using three established tools in a cohort of waitlist candidates.

Methods
Waitlist candidates were prospectively enrolled from 2016 to 2020 across five centers. Frailty was measured using the Frailty Phenotype (FP), a 37-variable frailty index (FI), and the Clinical Frailty Scale (CFS). The FI and CFS were dichotomized using established cutoffs. Agreement was compared using κ coefficients. Area under the receiver operating characteristic (ROC) curves were generated to compare the FI and CFS (treated as continuous measures) with the FP. Unadjusted associations between each frailty measure and time to death or waitlist withdrawal were determined using an unadjusted Cox proportional hazards model.

Results
Of 542 enrolled patients, 64% were male, 80% were White, and the mean age was 54±14 years. The prevalence of frailty by the FP was 16%. The mean FI score was 0.23±0.14, and the prevalence of frailty was 38% (score of ≥0.25). The median CFS score was three (IQR, 2–3), and the prevalence was 15% (score of ≥4). The κ values comparing the FP with the FI (0.44) and CFS (0.27) showed fair to moderate agreement. The area under the ROC curves for the FP and FI/CFS were 0.86 (good) and 0.69 (poor), respectively. Frailty by the CFS (HR, 2.10; 95% CI, 1.04 to 4.24) and FI (HR, 1.79; 95% CI, 1.00 to 3.21) was associated with death or permanent withdrawal. The association between frailty by the FP and death/withdrawal was not statistically significant (HR, 1.78; 95% CI, 0.79 to 3.71).

Conclusion
Frailty prevalence varies by the measurement tool used, and agreement between these measurements is fair to moderate. This has implications for determining the optimal frailty screening tool for use in those being evaluated for kidney transplant.
Developing Nurse Educators’ Self-Editing Skills in English Writing through a Checklist
Authors: Akdemir Ahmet Selçuk 
Published: May 2021

This study investigated the efficiency of self-editing to reduce language errors of nurse educators. To achieve this, a checklist was created and 15 nurse educators from three different universities were educated on how to self-edit throughout 10 weeks. Data were obtained through 3 editing tasks before the 10-week education course and 3 editing tasks after the course. The Wilcox on test analysed pre-tests and post-tests, and found a statistically significant difference in terms of noticing the language errors through self-editing. This study suggests nurse educators use the checklist before submitting a manuscript. Also, this study concludes that self-editing is an efficient way of revealing language errors and increasing accuracy in English writing of nurse educators.
Demographic and clinical characteristics of traumatic shoulder dislocations in an eastern Anatolian city in Turkey: A retrospective single-centre analysis of 181 patients
Authors: Cengiz Ömer , Dırvar Ferdi 
Published: May 2021

Objective: This study aims to investigate demographic and clinical characteristics of traumatic shoulder dislocations in an Eastern Anatolian city (Muş) in Turkey.
Material and Methods: Digital patient database was reviewed to identify the glenohumeral shoulder dislocations admitted to the emergency department between January 2017 and December 2018. Incidence, demographics, recurrence, associated injuries, and mechanism of injury were evaluated.
Results: One hundred and eighty-one patients (140 males, 41 females; mean age: 39.98±20.41 years) experienced traumatic shoulder dislocation during the study period. The incidence was 18,9 per 100,000 person-years. Age distribution peaked between 21 and 30 (94.5% male) and between 61 and 70 years. Primary shoulder dislocation occurred in 153, recurrent dislocations in 28, and anterior dislocations in 177 patients. The mechanism of injury included falls in 144 and sports injuries in 18 cases. The reduction was achieved in 154 patients in the emergency department.
Conclusion: The incidence of traumatic shoulder dislocations in Muş was higher than the study conducted in Turkey but similar to those in Europe, the UK, and the USA. Risk factors included young age (21-40) and participation in sports in men but fall and being in the 6th decade in women.

A Índia, lar do pior surto de Covid-19 em andamento no mundo, relatou mais de 17,6 milhões de casos desde o início da pandemia, no ano passado. Mas o número real, temem os especialistas, pode ser até 30 vezes maior — o que significa mais de meio bilhão de casos. As mortes, que oficialmente estão na casa das 200 mil, também estão subnotificadas e o número real pode ser de 400 mil ou de quase 1 milhão no pior cenário, segundo um estudo da Universidade de Michigan, nos Estados Unidos.
PROBLEMATIC ASPECTS OF LITHUANIAN LEGAL REGULATION OF IMPEACHMENT PROCEDURE TO A MEMBER OF LOCAL MUNICIPAL COUNCIL
Authors:   Kazimieras Simonavičius University,Lithuania, Kaklys Karolis 
Published: May 2021

Although members and mayors of municipal councils are not included in the list of persons who may be subject of Impeachment proceedings under the Constitution, a peculiar variant of the institute of Impeachment is the procedure of premature loss of authority of a mayor or a member of the local municipal council, which is established in Article 25 (1) of the Law on Local Self‐	Government of the Republic of Lithuania. In a democratic system it is vitally important that every local politician who takes an oath takes full responsibility, regardless of whether he works in the majority or minority of the municipal council and/or to which political force he belongs. The problematic aspect is that it is very complicated to initiate the impeachment proceedings on a politician who belongs to the majority and has broken the oath, and there are almost no practical possibilities to complete it as such possibilities remain only theoretical and very poorly feasible. The main tasks of the research is to determine practical and theoretical possibilities to initiate Impeachment proceedings against politiciansin the majority;to revealthe essential problematic aspects of legal regulation of Impeachment procedure to a member (or a mayor) of municipal council and to draw some solutions related to these questions analysed for Lithuanian legislator in order to improve national legal regulation. The research was carried out by employing logical, comparative, system analysis, monitoring, linguistic, empirical, synthesis and generalization methods.
Poking Holes: Looking for Gaps in LIGO/Virgo’s Black Hole Population
Authors: Edelman Bruce , Doctor Zoheyr , Farr Ben 
Published: May 2021

Abstract
Stellar evolution models predict the existence of a gap in the black hole mass spectrum from ∼55 M
⊙–120 M
⊙ due to pair-instability supernovae (PISNe). We investigate the possible existence of such an “upper” mass gap in the second gravitational-wave transient catalog (GWTC-2) by hierarchically modeling the astrophysical distribution of black hole masses. We extend the Truncated and Powerlaw+Peak mass distribution families to allow for an explicit gap in the mass distribution, and apply the extended models to GWTC-2. We find that with the Truncated model there is mild evidence favoring an upper mass gap with log Bayes Factor

, inferring the lower and upper bounds at

and

respectively. When using the Powerlaw+Peak model, we find no preference for the gap. When imposing tighter priors on the gap bounds centered on the expected PISNe gap bounds, the log Bayes factors in favor of a gap mildly increase. These results are however contingent on the parameter inference for the most massive binary, GW190521, for which follow-up analyses showed the source may be an intermediate mass ratio merger that has component masses straddling the gap. Using the GW190521 posterior samples from the analysis in Nitz & Capano (2021), we find an increase in Bayes factors in favor of the gap. However, the overall conclusions are unchanged: there is no preference for a gap when using the Powerlaw+Peak model. This work paves the way for constraining the physics of pair-instability and pulsational pair-instability supernovae and high-mass black hole formation.
Superadiabaticity in Jupiter and Giant Planet Interiors
Authors: Debras Florian , Chabrier Gilles , Stevenson David J. 
Published: May 2021

Abstract
Interior models of giant planets traditionally assume that at a given radius (i.e., pressure) the density should be larger than or equal to the one corresponding to a homogeneous, adiabatic stratification throughout the planet (referred to as the “outer adiabat”). The observations of Jupiter’s gravity field by Juno combined with the constraints on its atmospheric composition appear to be incompatible with such a profile. In this Letter, we show that the above assumption stems from an incorrect understanding of the Schwarzschild–Ledoux criterion, which is only valid on a local scale. In order to fulfill the buoyancy stability condition, the density gradient with pressure in a nonadiabatic region must indeed rise more steeply than the local adiabatic density gradient. However, the density gradient can be smaller than the one corresponding to the outer adiabat at the same pressure because of the higher temperature in an inhomogeneously stratified medium. Deep enough, the density can therefore be lower than the one corresponding to the outer adiabat. We show that this is permitted only if the slope of the local adiabat becomes shallower than the slope of the outer adiabat at the same pressure, as found in recent Jupiter models due to the increase of both specific entropy and adiabatic index with depth. We examine the dynamical stability of this structure and show that it is stable against nonadiabatic perturbations. The possibility of such an unconventional density profile in Jupiter further complicates our understanding of the internal structure and evolution of (extrasolar) giant planets.
System-level Fractionation of Carbon from Disk and Planetesimal Processing
Authors: Lichtenberg Tim , Krijt Sebastiaan 
Published: May 2021

Abstract
Finding and characterizing extrasolar Earth analogs will rely on interpretation of the planetary system’s environmental context. The total budget and fractionation between C–H–O species sensitively affect the climatic and geodynamic state of terrestrial worlds, but their main delivery channels are poorly constrained. We connect numerical models of volatile chemistry and pebble coagulation in the circumstellar disk with the internal compositional evolution of planetesimals during the primary accretion phase. Our simulations demonstrate that disk chemistry and degassing from planetesimals operate on comparable timescales and can fractionate the relative abundances of major water and carbon carriers by orders of magnitude. As a result, individual planetary systems with significant planetesimal processing display increased correlation in the volatile budget of planetary building blocks relative to no internal heating. Planetesimal processing in a subset of systems increases the variance of volatile contents across planetary systems. Our simulations thus suggest that exoplanetary atmospheric compositions may provide constraints on when a specific planet formed.

Published: May 2021

Abstract
Nulling pulsars are pulsars whose observed flux occasionally disappears, but the mechanism behind the cessation is not well understood. Motivated by the correlation between pulse width and nulling fraction found in Sheikh & MacDonald, we compile all 378 nulling pulsars to date with their pulse widths in a machine-readable table. We also include the observing frequency and time resolution of each pulse width measurement. Such a table will be useful for future studies of this population.
Flora of Vladimir Oblast, Russia: an updated grid dataset (1867–2020)
Authors: Seregin Alexey P. 
Published: May 2021

The dataset covers wild tracheophytes (native species, naturalised aliens and casuals) of Vladimir Oblast, Russia. It includes only one occurrence per species per grid square, thereby recently confirmed earlier records are not duplicated. Georeferences are based on the WGS84 grid scheme with 342 squares with areas ranging from 94.7 km2 in the northernmost part to 98.2 km2 on the southern boundary (5′ lat. × 10′ long.). Each occurrence is linked to the corresponding grid square centroid, therefore actual coordinates, habitat details and voucher information are unavailable. In late 2011, the earlier version of the dataset was used for the production of grid maps in the standard "Flora of Vladimir Oblast: checklist and atlas". Additional records, obtained during field excursions of 2012 and 2013, were fully included in the "Flora of Vladimir Oblast: grid data analysis". The stable version of the dataset with 123,054 grid records (as of 1867–2013) was published in GBIF in 2017.
Data obtained in the field during 2014–2020, as well as those extracted from recently published sources, were digitised, structured and finally published in GBIF in April 2021. The last update added 7,000 new grid records. Currently, "Flora of Vladimir Oblast, Russia: an updated grid dataset (1867–2020)" contains 130,054 unique occurrences of 1,465 vascular plant taxa (species, hybrids, species aggregates) from Vladimir Oblast and tiny parts of the adjacent areas. The average number of grid records has grown over the seven years from 363 to 380 species. The grid occurrences are largely based on the field studies by the author, performed during 1999–2020 (121,737 records), as well as on data extracted from the relevant literature, unpublished sources, herbarium collections and citizen science projects (8,317 records). The taxonomic backbone of the occurrence grid dataset follows the accompanying checklist dataset to ensure correct cross-linking of the names. As of April 2021, the dataset on the Vladimir Oblast flora represents the fourth largest dataset on vascular plants of Russia published in GBIF.
Retour sur la coproduction franco-anglo-américaine d’Alice au pays des merveilles de Lou Bunin (1949)
Authors: Roffat Sébastien 
Published: May 2021

L’article revient sur la production, en 1947-1949 d’un film d’animation franco-anglo-américain, Alice au Pays des merveilles, réalisé par Lou Bunin, sculpteur et marionnettiste américain d’extrême-gauche, ami de Diego Rivera et Tina Modotti, qui a fui l’Amérique de la « chasse aux sorcières ». Accueilli par des techniciens, acteurs, cinéastes et producteurs membres du PCF ou proches de lui, Bunin fait venir des États-Unis des animateurs licenciés par Walt Disney pour fait de grève et d’autres « black-listés » comme lui. Le film devait inaugurer une production d’animation française originale. Tourné en deux langues il bénéficie du système d’aide du Crédit national et de la distribution par l’UGC récemment constituée après la saisie par l’État des biens allemands notamment ceux de la Continental, qui participe à son financement. Dans le climat de « guerre froide », le film rencontre l’hostilité de la presse de droite qui s’indigne que les fonds publics aient financé un film « américano-communiste » tandis qu’aux États-Unis Walt Disney fait tout pour entraver la diffusion du film de Bunin qui tomba dans l’oubli. Grâce à l’exploitation inédite des archives du Crédit national et d’autres fonds ainsi que du dépouillement de la presse de l’époque, cet article retrace les conditions de production de ce film et le sort qui fut le sien.

L’article cherche à donner une vision d’ensemble de la vie et de l’œuvre de Tereza D’Amico. Artiste à la solide formation technique, elle choisit à partir de 1957 d’adopter le langage des artistes populaires et autodidactes. Utilisant leur vocabulaire, elle produisit un maniérisme qui s’inspire des spécificités formelles des artistes dits primitifs, que le milieu artistique brésilien était alors en train de « découvrir ». Bien accueilli par les critiques de son temps, son travail pose des questions inhabituelles pour son époque.

Published: May 2021

Background:
Dengue is a common endemic infection in India. Neurological complications involving various parts of the neuro-axis have been reported. We report neurological complications amongst dengue patients admitted to a tertiary hospital in Western India.

Materials and Methods:
Patients admitted in a tertiary hospital in Western India with dengue infection and having neurological symptoms were included in this study. Their history, physical examination, laboratory investigations and imaging studies were obtained from the inpatient records and analysed.

Results:
Between January 2014 to December 2019, a total of 5821 patients were diagnosed with dengue. Of these, 154 (2.64%) had neurological manifestations. Encephalopathy in a setting of multisystem involvement was seen in 31.2% patients, encephalitis with focal features, abnormal imaging and/or abnormal cerebrospinal fluid (CSF) examination was seen in 15.6%, syncope in 27.3% and acute symptomatic seizure in 11.0%. Less common presentations were intracranial haemorrhage (4.5%), Guillain-Barre syndrome (GBS) (3.2%), optic neuritis (1.9%), myositis (1.3%), hypokalemic paralysis (1.3%), ischemic stroke (0.6%), posterior reversible encephalopathy syndrome (PRES) (0.6%), myoclonus (0.6%) and brachial plexopathy (0.6%).

Conclusions:
In this study of patients admitted with dengue, neurological complications due to dengue were seen in 2.64%. Encephalopathy, encephalitis and syncope were the commonest manifestations, followed by acute symptomatic seizures, intracranial haemorrhage and GBS. The entire neuroaxis can be involved in dengue infection. To the best of our knowledge, this is the largest reported study of neurological complications of dengue.

Published: May 2021

The bioavailability of phosphorus and other nutrients in feed for monogastrics is restricted by the presence of phytate. Exogenous supply of phytase produced by bacteria and other microbes can enhance the bioavailability of these nutrients and reduce phosphorus pollution. The objective of the study was to isolate bacteria with phytase-producing potentials from soil; which may be employed for the bioavailability of phosphorus and other nutrients in feed for monogastrics in Nigeria. Top soil samples were collected from two dumpsites in Lagos, Nigeria and bacteria were isolated and screened for potentials to produce phytase. The isolates with phytase potential were primarily identified by their cultural and biochemical characteristics and then confirmed using the 16S rRNA sequencing, after which their expressed phytases were quantified. A total of six isolates belonging to three species were identified as phytase producers. Sequence data analyses revealed these to be Bacillus subtilis (2), Bacillus amyloliquefaciens (3) and Enterobacter cloacae (1) with accession numbers MH879827 and MH879832; MH879828, MH879830 and MH879831; and MH879829 respectively. Phenotypic phytase activity was highest in E. cloacae ODS 29 (9.69 ± 0.04 U/ml) and least in B. subtilis ODS 10 (8.83 ± 0.02 U/ml). In conclusion, phytase-producing Bacillus and Enterobacter species were isolated and characterized from Nigerian soils. These bacteria species could be used in biotechnological applications.

Phytoremediation of diesel and spent engine oil contaminated soil using Kariya (Hildergardia barteri Mast.) seedlings
Authors: Olajuyigbe S.O. , Fayinminnu O.O. , Ayoade A.O. 
Published: May 2021

Using a completely randomized design experiment, the effect of different levels of diesel and spent engine oil contamination (0 mL/kg, 25 mL/kg, 50 mL/kg and 75 mL/kg of soil) on growth performance (seedling height, collar diameter, number of leaves and biomass accumulation) of Hildergardia barteri seedlings were assessed for twelve weeks. The concentration of Lead, Nickel, Copper and Zinc in the plant parts were also determined. Data were analysed using descriptive and inferential statistics at P<0.05 level of significance. There were significant differences in the effects of diesel and spent engine oil on growth performance of seedlings based on contamination levels. Control treatment had the highest height (92.43±5.13 cm), collar diameter (16.23±0.98 mm), number of leaves (11.21±0.47) and total biomass (33.01±12.79 g). Seedlings exposed to 50 mL/kg treatments had the least height (diesel oil: 78.21±7.22 cm; spent engine oil: 79±6.24 cm); those exposed to 75 mL/kg contamination had the least collar diameter (diesel oil: 8.85±1.05 mm, spent engine oil: 12.02±1.01 mm), while seedlings treated with 50 mL/kg diesel oil (2.21±0.37) and 75 mL/kg spent engine oil (4.79±0.55) had the lowest number of leaves. Heavy metal bio-accumulation ranges were: Lead: 0.17-0.39 mg/kg, Nickel: 0.09–0.45 mg/kg, Copper: 0.54–1.08 mg/kg, Zinc: 0.88–1.58 mg/kg. The ability of the seedlings to survive and bio-accumulate heavy metals indicate the potential phytoremediation capabilities of Hildergardia barteri.
