Targeting optimal PD management in children: what have we learned from the IPPN registry?
Authors: Borzych-Dużałka Dagmara , Schaefer Franz , Warady Bradley A. 
Published: May 2020

AbstractNational and international registries have great potential for providing data that describe disease burden, treatments, and outcomes especially in rare diseases. In the setting of pediatric end-stage renal disease (ESRD), the available data are limited to highly developed countries, whereas the lack of data from emerging economies blurs the global perspective. In order to improve the pediatric dialysis care worldwide, provide global benchmarking of pediatric dialysis outcome, and assign useful tools and management algorithms based on evidence-based medicine, the International Pediatric Peritoneal Dialysis Network (IPPN) was established in 2007. In recent years, the Registry has provided comprehensive data on relevant clinical issues in pediatric peritoneal dialysis patients including nutritional status, growth, cardiovascular disease, anemia management, mineral and bone disorders, preservation of residual kidney function, access-related complications, and impact of associated comorbidities. A unique feature of the registry is the ability to compare practices and outcomes between countries and world regions. In the current review, we describe study design and collection methods, summarize the core IPPN findings based on its 12-year experience and 13 publications, and discuss the future perspective.

Zusammenfassung
Hintergrund
Rettungsdienst und Notaufnahmen werden zunehmend durch nichtlebensbedrohlich erkrankte Patienten belastet. In England und den USA wurden zur Versorgung vor Ort bereits vor einigen Jahren Community-paramedic-Systeme etabliert.
Auf diesen Konzepten basierend wurde ein an das deutsche Rettungswesen adaptierte System „Gemeindenotfallsanitäter“ (G-NFS) entwickelt. Das Ziel des G‑NFS ist, eine unnötige Disponierung höherwertiger Rettungsmittel zu reduzieren.

Ziel
Deskriptive Analyse der in den ersten 12 Monaten erhobenen Daten.

Methodik
Es handelt sich um eine retrospektive Beobachtungsstudie auf Basis der Einsatzdokumentation im Jahr 2019.

Ergebnisse
Es wurden 3703 Einsatzprotokolle ausgewertet. Das Durchschnittsalter betrug 62,2 ± 24,7 Jahre. Bei 2186 (61,1 %) Patienten wurde die Behandlungspriorität „0“ gewählt, d. h.: Es lag keine Dringlichkeit der Versorgung vor. 2134 (59 %) Patienten benötigten kein weiteres Rettungsmittel, eine ambulante Versorgung vor Ort war ausreichend. Am häufigsten wurde den Patienten die Vorstellung beim Hausarzt (n = 1422, 38 %) sowie die Vorstellung in der Notaufnahme (n = 1222, 33 %) empfohlen. Aus Sicht der G‑NFS wurden 3058 (85 %) Einsätze von den Leitstellendisponenten richtig kategorisiert.

Diskussion
Durch die gezielte Alarmierung der neu geschaffenen Ressource „Gemeindenotfallsanitäter“ können Patienten ambulant vor Ort versorgt werden und folglich die Institutionen der Notfallversorgung entlastet werden. Im weiteren Projektverlauf ist zu untersuchen, was die Einsatzindikationen bei den 1480 (41 %) Einsätzen mit einer Nachalarmierung von Rettungsmitteln sind und wie die Einschätzung der Leitstelle verbessert werden kann.
A Compact Two-Frequency Notch Filter for Millimeter Wave Plasma Diagnostics

Published: May 2020

AbstractSensitive millimeter wave diagnostics in magnetic confinement plasma fusion experiments need protection from gyrotron stray radiation in the plasma vessel. Modern electron cyclotron resonance heating (ECRH) systems take advantage of multi-frequency gyrotrons. This means that the frequency band of some millimeter wave diagnostics contains more than one narrow-band gyrotron-frequency line, which needs to be effectively suppressed. A compact standard waveguide notch filter based on coupled waveguide resonators with rectangular cross-section is presented which can provide very high suppression of several gyrotron frequencies and has low insertion loss of the passband.
Momentum effects in the cryptocurrency market after one-day abnormal returns
Authors: Caporale Guglielmo Maria , Plastun Alex 
Published: May 2020

AbstractThis paper examines whether there exists a momentum effect after one-day abnormal returns in the cryptocurrency market. For this purpose, a number of hypotheses of interest are tested for the Bitcoin, Ethereum and Litecoin exchange rates vis-à-vis the US dollar over the period 01.01.2015–01.09.2019, specifically whether or not: (H1) the intraday behavior of hourly returns is different on abnormal days compared to normal days; (H2) there is a momentum effect on days with abnormal returns, and (H3) after one-day abnormal returns. The methods used for the analysis include various statistical methods as well as a trading simulation approach. The results suggest that hourly returns during the day of positive/negative abnormal returns are significantly higher/lower than those during the average positive/negative day. The presence of abnormal returns can usually be detected before the day ends by estimating specific timing parameters. Prices tend to move in the direction of the abnormal returns till the end of the day when it occurs, which implies the existence of a momentum effect on that day giving rise to exploitable profit opportunities. This effect (together with profit opportunities) is also observed on the following day. In two cases (BTCUSD positive abnormal returns and ETHUSD negative abnormal returns), a contrarian effect is detected instead.
The Double-Edged Interactions of Prompts and Self-efficacy
Authors: Gentner Nadja , Seufert Tina 
Published: May 2020

AbstractBy activating self-regulation processes, prompts affect strategy use and learning outcomes. This study investigates the effects of cognitive and metacognitive prompts on strategy use and learning outcomes. Since enactive self-regulation processes represent the basis for self-efficacy judgements, we also investigated the effects of cognitive and metacognitive prompts on the development of learners’ self-efficacy. Alternatively, based on the concept of aptitude-treatment interactions, it is proposed that learners’ self-efficacy moderates the effects of prompts on learners’ self-reported online strategy use and their learning outcomes. While learning with hypermedia, N = 70 students either received cognitive and metacognitive prompts or learned without prompts. Self-efficacy was measured before, during, and directly after learning. Learning outcomes were assessed after learning. Strategy use was assessed via self-report and the quality of learning strategies in learners’ notes. Prompting had no effect on self-reported cognitive and metacognitive online strategy use, the quality of learning strategies, and learning outcomes but increased learners’ self-efficacy within the experimental group. Following the theoretical argumentation of aptitude-treatment interactions, moderation analyses indicated that the effect of prompts on learning outcomes was dependent on learners’ self-efficacy during learning. Thus, learners perceived self-efficacy during learning influenced the effectiveness of the prompts. Further research should investigate the interrelations between cognitive, metacognitive, and motivational factors to better understand how self-regulation can effectively be fostered in hypermedia environments.
Spatial structure of woody cover affects habitat use patterns of ocelots in Texas

Published: May 2020

AbstractAbout 80% of the known breeding population of ocelots (Leopardus pardalis) in the USA occurs exclusively on private ranches in northern Willacy and Kenedy counties in South Texas. These private ranches support several large contiguous undisturbed patches of thornscrub, which is preferred by ocelots. Past studies have indicated ocelots in South Texas select for woody patches that contain extremely dense thornscrub (i.e., 95% canopy cover and 85% vertical cover) and require large patches of woody cover to survive. Landscape metrics have been used to explain ocelot habitat use in fragmented areas, but their application in less-fragmented rangelands is lacking. From 2011 to 2018, we used camera traps on the East Foundation’s El Sauz Ranch to assess seasonal habitat use of ocelots relative to landscape structure, configuration, and complexity and other site-level factors in South Texas. Seasonal habitat use and detection were positively influenced by larger mean patch area and lower landscape shape index values. We also observed ocelots were less likely to be detected during periods of drought and exhibited a seasonal trend in detection. Ocelots used woody patches that were larger and more regularly shaped, indicating a preference for areas with a lower degree of fragmentation across the study area. As patches become larger, they will coalesce over time and form larger woody aggregates, which will promote ocelot habitat use. Brush management needs to be strategic as patch area and shape index are a limiting factor to promote ocelot habitat use on working rangelands in South Texas. These results demonstrate the ability to use landscape metrics to discern the effects of spatial structure of vegetation communities relative to ocelot occupancy parameters.
Experimental study on atomization characteristics and dust-reduction performance of four common types of pressure nozzles in underground coal mines
Authors: Han Han , Wang Pengfei , Liu Ronghua , Tian Chang 
Published: May 2020

AbstractPressure nozzle is commonly used in the dust-reduction techniques by spraying of underground coal mines. Based on the internal structure, the pressure nozzle can be divided into the following types: spiral channel nozzle, tangential flow-guided nozzle and X-swirl nozzle. In order to provide better guidance on the selection of nozzles for the coal mine dust-reduction systems by spraying, we designed comparing experiments to study the atomization characteristics and dust-reduction performance of four commonly used nozzles in the coal mine underground with different internal structures. From the experimental results on the atomization characteristics, both the tangential flow-guided nozzle and the X-swirl nozzle have high flow coefficients. The atomization angle is the largest in the spiral non-porous nozzle, and smallest in both the X-swirl nozzle and the spiral porous nozzle. The spraying range and the droplet velocity are inversely proportional to the atomization angle. When the water pressure is low, the atomization performance of the spiral non-porous nozzle is the best among the four types of nozzles. The atomization performance of the X-swirl nozzle is superior to other types when the water pressure is high. Under the high water pressure, the particle size of the atomized droplets is smallest in the X-swirl nozzle. Through the experiments on the dust-reduction performance of the four types of nozzles and the comprehensive analysis, the X-swirl nozzle is recommended for the coal mine application site with low water pressure in the dust-reduction system, while at the sites with high water pressure, the spiral non-porous nozzle is recommended, which has the lowest water consumption and obvious economic advantages.
Caring Actions
Authors: Steyl Steven 
Published: May 2020

AbstractThough the literature on care ethics has mushroomed in recent years, much remains to be said about several important topics therein. One of these is action. In this article, I draw on Anscombean philosophy of action to develop a kind of meta- or proto-ethical theory of caring actions. I begin by showing how the fragmentary philosophy of action offered by care ethicists meshes with Elizabeth Anscombe's broader philosophy of action, and argue that Anscombe's philosophy of action offers a useful scaffold for a theory of caring actions. Following this, I defend an account of caring actions as those that aim to meet needs. I argue that care aims at satisfying eudaimonistic needs, those things without which one cannot flourish. I then consider the place of caring actions in care ethics. I suggest that if caring actions are to be a starting point for an ethical theory, we ought to reject the notion that a caring action must bring about its intended consequences, and I show how the concept of practice better equips us to evaluate caring actions.
Particle trajectories in Weibel filaments: influence of external field obliquity and chaos
Authors: Bret A. , Dieckmann M. E. 
Published: May 2020

When two collisionless plasma shells collide, they interpenetrate and the overlapping region may turn Weibel unstable for some values of the collision parameters. This instability grows magnetic filaments which, at saturation, have to block the incoming flow if a Weibel shock is to form. In a recent paper (Bret, J. Plasma Phys., vol. 82, 2016b, 905820403), it was found by implementing a toy model for the incoming particle trajectories in the filaments, that a strong enough external magnetic field

$\unicode[STIX]{x1D63D}_{0}$

can prevent the filaments blocking the flow if it is aligned with them. Denoting by

$B_{f}$

the peak value of the field in the magnetic filaments, all test particles stream through them if

$\unicode[STIX]{x1D6FC}=B_{0}/B_{f}>1/2$

. Here, this result is extended to the case of an oblique external field

$B_{0}$

making an angle

$\unicode[STIX]{x1D703}$

with the flow. The result, numerically found, is simply

$\unicode[STIX]{x1D6FC}>\unicode[STIX]{x1D705}(\unicode[STIX]{x1D703})/\cos \unicode[STIX]{x1D703}$

, where

$\unicode[STIX]{x1D705}(\unicode[STIX]{x1D703})$

is of order unity. Noteworthily, test particles exhibit chaotic trajectories.
The contribution of orthographic input, phonological skills, and rise time discrimination to the learning of non-native phonemic contrasts
Authors: Bhide Adeetee , Ortega-Llebaria Marta , Fraundorf Scott H. , Perfetti Charles A. 
Published: May 2020

AbstractAlthough learning second language phonology is a difficult task, orthographic input may support the learning of difficult sound contrasts through a process known as orthographic facilitation. We extended this research by examining the effects of orthographic input together with individual differences in three different phonological learning processes, namely, the production of, perception of, and memorization of words containing three Marathi phonemic contrasts (i.e., [k-kh], [], and []) by native English speakers. Moreover, because the [] and [] contrasts were particularly challenging in previous auditory training studies (e.g., Polka, 1991), we used cross-modal training in order to enhance learning by pairing auditory perception tasks with visual orthographic information, the amplification of relevant acoustic cues, and proprioceptive descriptions to the articulation of target phonemes. Results showed significant learning from the pre- to the posttest across tasks and contrasts, supporting the effectiveness of cross-modal training. Furthermore, incongruent orthographic input could inhibit perception, and orthographic input generally supported memory for word pronunciations. Moreover, individual differences regarding phonological skills and nonspeech auditory discrimination predicted participants’ success in different phonological learning processes. These results provide a detailed picture of the complexity between different aspects of second language phonological learning and cross-modal training.

AbstractObjective:To assess the prevalence of underweight, overweight and obesity in French children from 2013 to 2017.Design:Cross-sectional study performed in fourteen regions of France. Physical measures included weight, height and BMI. Underweight, overweight and obesity were defined according to age- and sex-specific BMI cut-off points from the International Obesity Task Force.Setting:France.Subjects:Children (10 159 boys, 9757 girls) from the voluntary, non-representative Diagnoform programme between 2013 and 2017, at the age of 4–12 years.Results:The prevalence of overweight and obesity was higher in girls compared with boys (P < 0·001). Underweight was also more prevalent in girls (P < 0·05). Although there were no significant changes in the prevalence of obesity in boys or girls from 2013 to 2017, a significant decrease in overweight among boys and girls was found (P < 0·001) during the same time period. In contrast, the prevalence of underweight increased in girls and boys (from 10·0 to 20·0 %, P < 0·0001) between 2013 and 2017.Conclusions:Results of the current study show that the prevalence of obesity was stable, while the prevalence of overweight decreased significantly, despite high in French children. Findings suggest also that thinness is becoming an important phenomenon in children. Developing preventive and nutritional programmes in order to modify the lifestyle might help control underweight and obesity in children.
Interplanetary transmissions of life in an evolutionary context
Authors: von Hegner Ian 
Published: May 2020

AbstractThe theory of lithopanspermia proposes the natural exchange of organisms between solar system bodies through meteorites. The focus of this theory comprises three distinct stages: planetary ejection, interplanetary transit and planetary entry. However, it is debatable whether organisms transported within the ejecta can survive all three stages. If the conjecture is granted, that life can indeed be safely transmitted from one world to another, then it is not only a topic pertaining to planetary science but also biological sciences. Hence, these stages are only the first three factors of the equation. The other factors for successful lithopanspermia are the quality, quantity and evolutionary strategy of the transmitted organisms. When expanding into new environments, invading organisms often do not survive in the first attempt and usually require several attempts through propagule pressure to obtain a foothold. There is a crucial difference between this terrestrial situation and the one brought about by lithopanspermia. While invasive species on Earth repeatedly enters a new habitat, a species pragmatically arrives on another solar system body only once; thus, an all-or-nothing response will be in effect. The species must survive in the first attempt, which limits the probability of survival. In addition, evolution sets a boundary through the existence of an inverse proportionality between the exchanges of life between two worlds, thus further restricting the probability of survival. However, terrestrial populations often encounter unpredictable and variable environmental conditions, which in turn necessitates an evolutionary response. Thus, one evolutionary mode in particular, bet hedging, is the evolutionary strategy that best smooth out this inverse proportionality. This is achieved by generating diversity even among a colony of genetically identical organisms. This variability in individual risk-taking increases the probability of survival and allows organisms to colonize more diverse environments. The present analysis to understand conditions relevant to a bacterial colony arriving in a new planetary environment provides a bridge between the theory of bet hedging, invasive range expansion and planetary science.

AbstractThe Earth's climate is rapidly changing. Over the past centuries, aerosols, via their ability to absorb or scatter solar radiation and alter clouds, played an important role in counterbalancing some of the greenhouse gas (GHG) caused global warming. The multicentury anthropogenic aerosol cooling effect prevented present‐day climate from reaching even higher surface air temperatures and subsequent more dramatic climate impacts. Trends in aerosol concentrations and optical depth show that in many polluted regions such as Europe and the United States, aerosol precursor emissions decreased back to levels of the 1950s. More recent polluting countries such as China may have reached a turning point in recent years as well, while India still follows an upward trend. Here we study aerosol trends in the Coupled Model Intercomparison Project Phase 6 (CMIP6) simulations of the GISS ModelE2.1 climate model using a fully coupled atmosphere composition configuration, including interactive gas‐phase chemistry and either an aerosol microphysical (MATRIX) or a mass‐based (One‐Moment Aerosol, OMA) aerosol module. Results show that whether global aerosol radiative forcing is already declining depends on the aerosol scheme used. Using the aerosol microphysical scheme, where the aerosol system reacts more strongly to the trend in sulfur dioxide (SO2) emissions, global peak direct aerosol forcing was reached in the 1980s, whereas the mass‐based scheme simulates peak direct aerosol forcing around 2010.
Gitelman syndrome caused by a novel hemiallelic missense mutation in SLC12A3 revealed by 16q12.2q21 microdeletion

Published: May 2020

AbstractGitelman syndrome (GS) is caused by biallelic mutations in SLC12A3 as an autosomal recessive trait. A patient with a de novo 16q12.2q21 microdeletion showed clinical features of GS. SLC12A3 included in the deletion was analyzed, and a rare missense variant (c.1222A>C [p.N406H]) was identified as hemizygous. Consequently, GS was caused by the revealed SLC12A3 variant owing to chromosomal microdeletion.

AbstractThe earthworm is particularly fascinating to biologists because of its strong regenerative capacity. However, many aspects of its regeneration in nature remain elusive. Here we report chromosome-level genome, large-scale transcriptome and single-cell RNA-sequencing data during earthworm (Eisenia andrei) regeneration. We observe expansion of LINE2 transposable elements and gene families functionally related to regeneration (for example, EGFR, epidermal growth factor receptor) particularly for genes exhibiting differential expression during earthworm regeneration. Temporal gene expression trajectories identify transcriptional regulatory factors that are potentially crucial for initiating cell proliferation and differentiation during regeneration. Furthermore, early growth response genes related to regeneration are transcriptionally activated in both the earthworm and planarian. Meanwhile, single-cell RNA-sequencing provides insight into the regenerative process at a cellular level and finds that the largest proportion of cells present during regeneration are stem cells.
