Abstract
We present observations of planetary nebulae with the LOw Frequency ARray (LOFAR) between 120 and 168 MHz. The images show thermal free–free emission from the nebular shells. We have determined the electron temperatures for spatially resolved, optically thick nebulae. These temperatures are 20%–60% lower than those estimated from collisionally excited optical emission lines. This strongly supports the existence of a cold plasma component, which co-exists with hot plasma in planetary nebulae. This cold plasma does not contribute to the collisionally excited lines, but does contribute to recombination lines and radio flux. Neither of the plasma components are spatially resolved in our images, although we infer that the cold plasma extends to the outer radii of planetary nebulae. However, more cold plasma appears to exist at smaller radii. The presence of cold plasma should be taken into account in modeling of radio emission of planetary nebulae. Modelling of radio emission usually uses electron temperatures calculated from collisionally excited optical and/or infrared lines. This may lead to an underestimate of the ionized mass and an overestimate of the extinction correction from planetary nebulae when derived from the radio flux alone. The correction improves the consistency of extinction derived from the radio fluxes when compared to estimates from the Balmer decrement flux ratios.
An Insight into the Coupling of CME Kinematics in Inner and Outer Corona and the Imprint of Source Regions

Abstract
Despite studying coronal mass ejections (CMEs) for several years, we do not yet have a complete understanding of their kinematics. To this end, it is essential to understand the change in kinematics of the CMEs as they travel from the inner corona (<3 R
⊙) up to the higher heights of the outer corona. We conduct a follow-up statistical study of several 3D kinematic parameters of 59 CMEs previously studied by Majumdar et al. (2020). The source regions of these CMEs are identified and classified as active regions (ARs), active prominences (APs), or prominence eruptions (PEs). We study several statistical correlations between different kinematic parameters of the CMEs. We show that the CMEs’ average kinematic parameters change as they propagate from the inner to the outer corona, indicating the importance of a region where the common practice is to perform averaging. We also find that the CME parameters in the outer corona are highly influenced by those in the inner corona, indicating the importance of the inner corona in the understanding of the kinematics. Furthermore, we find that the source regions of the CMEs tend to have a distinct imprint on the statistical correlations between different kinematic parameters, and that an overall correlation tends to wash away this crucial information. The results of this work supports the possibility of different dynamical classes for the CMEs from ARs and prominences, which gets manifested in their kinematics.

Abstract
We present a study of the east–west anisotropy of trapped-proton fluxes in low-Earth orbit based on the measurements of the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA) experiment. The differential intensities of eastward- and westward-traveling protons detected in the South Atlantic Anomaly region were estimated as a function of equatorial pitch angle and drift shell, for six energy bins between 80 MeV and 2 GeV. We found that, as a consequence of the strong atmospheric gradient coupled with the large gyroradius in this energy range, the intensities of eastward fluxes exceed those of westward fluxes by a factor of ∼10–20. However, the reported directional asymmetry also depends on the sign of the local flux gradient, resulting in more intense westward fluxes beyond the radial distances where the inner belt peaks. PAMELA observations can be used to improve the description of the near-Earth radiation environment at lowest altitudes and highest trapping energies, where current theoretical and empirical models are affected by the largest uncertainties.

Published: October 2021

To this day, merely 15% of all estimated fungi species are documented, and in certain regions, its biodiversity is practically unknown. Inside the Fungi Kingdom, macrofungi and lichens assume a critical part in the ecosystem functionality and have a historical connection to mankind's social, clinical and nutritious uses. Despite their importance, the diversity of these groups has been widely overlooked in the sub-Antarctic region of Chile, a crucial area in the study of climate change due to its extraordinary biodiversity and its proximity to Antarctica. Few studies regarding both groups have been conducted in this sub-Antarctic region but data are still scarce and inaccessible, as there are only published in specialized journals, unreachable to local communities.
This publication presents the records available in published scientific and technical reports on macrofungi and lichen diversity. In total, 987 occurrence records of 435 species (106 records of 95 macrofungi species 881 records of 340 lichen species) were digitized and integrated into the regional platform Biodiversity Information System for Aysén (SIB-Aysén) and into GBIF.

Aims: We studied the syntaxonomic position, biodiversity, ecological features, nature conservation value and current status of dry grasslands investigated by Josias Braun-Blanquet more than 60 years ago. Study area: Inner-alpine valleys of Austria. Methods: We sampled 67 plots of 10 m2, following the standardized EDGG methodology. We subjected our plots to an unsupervised classification with the modified TWINSPAN algorithm and interpreted the branches of the dendrogram syntaxonomically. Biodiversity, structural and ecological characteristics of the resulting vegetation units at association and order level were compared by ANOVAs. Results: All the examined grasslands belong to the class Festuco-Brometea. From ten distinguished clusters, we could assign four clusters to validly published associations, while the remaining six clusters were named tentatively. We classified them into three orders: Stipo-Festucetalia pallentis (Armerio elongatae-Potentilletum arenariae, Phleo phleoidis-Pulsatilletum nigricantis, Medicago minima-Melica ciliata community, Koelerio pyramidatae-Teucrietum montani), Festucetalia valesiacae (Sempervivum tectorum-Festuca valesiaca community); Brachypodietalia pinnati (Astragalo onobrychidis-Brometum erecti, Agrostis capillaris-Avenula adsurgens community, Anthericum ramosum-Brachypodium pinnatum community, Ranunculus bulbosus-Festuca rubra community, Carduus defloratus-Brachypodium pinnatum community). Conclusions: The ten distinguished dry grassland communities of the Austrian inner-alpine valleys differ in their ecological affinities as well as their vascular plant, bryophyte and lichen diversity. We point out their high nature conservation importance, as each of them presents a unique habitat of high value.
Taxonomic reference: Names of vascular plants, bryophytes and lichens follow Fischer et al. (2008), Frahm and Frey (2004) and Nimis et al. (2018), respectively.

Itinéraire d’une orthophoniste au cœur de la prévention en orthophonie
Authors: Ercolani-Bertrand Françoise 
Published: October 2021

Pour moi, orthophonie a rimé avec syndicalisme de terrain, ce qui m’a permis de formidables rencontres. Orthophonie a toujours rimé avec passion et envie d’avancer, et donc avec formations. Par chance, j’habite dans un département où orthophonie a toujours rimé avec prévention, domaine qui a été un grand « cheval de bataille » pour moi. Et enfin, orthophonie a toujours rimé avec amitié. Je veux juste ici témoigner de l’importance et de la richesse de la multi-disciplinarité dans le soin, et des échanges de points de vue sur les patients, mais aussi de la nécessité de la prévention.

Un synode très attendu
Authors: Baujard Monique , Grieu Étienne 
Published: October 2021

Le Synode sur la synodalité, dont la dernière étape aura lieu à Rome en 2023, se veut une démarche de longue durée qui doit impliquer l’ensemble des baptisés. En écho à la Lettre au peuple de Dieu de 2018, qui répondait à la crise des abus, il s’agit de penser un modèle d’Église qui écarte tout « cléricalisme ». En France, le collectif « Promesses d’Église » apporte des éléments de réflexion, en mettant en avant le thème de la fraternité et la prise en compte des personnes qui estiment ne pas avoir la parole dans l’Église.

➤ Qualifiés, dès leur parution en 1989, d’« eigentliches Werk », les Beiträge – comme on dit dans le jargon – s’en défendront, eux qui, du point de vue de leur fond, ne sont plus une œuvre pour finir et qui, du point de vue de leur dénomination, ne sont pas appropriés pour commencer. Car non content d’avoir une appellation, ils en ont deux, leur intitulé officiel : Beiträge zur Philosophie et leur titre essentiel : Vom Ereignis , celui-là méritant d’ailleurs autant, sinon plus de réflexion que celui-ci lorsqu’il s’agit d’établir sa traduction. C’est là ce à quoi nous nous employons, expliquant pourquoi il ne faut pas dire « Apports à la philosophie », avant de pointer du doigt la question à expliciter, celle de savoir en quoi ces Contributions à la philosophie contribuent à la philosophie – autrement dit contribuent à la question de la philosophie.

➤ Ce qui est en question dans le manuscrit rédigé par Heidegger entre 1936 et 1938 auquel il a donné le nom de Beiträge zur Philosophie , « Contributions à la philosophie », c’est « De l’ Ereignis », qui en constitue le véritable titre, comme il le précise d’emblée. Il s’agit en effet de penser sous ce nom la co-appartenance de l’homme et de l’être, seule manière de ne plus faire de ce dernier un objet. C’est dans les Beiträge qu’a alors lieu le « tournant » (Kehre) , c’est-à-dire le passage d’une pensée de l’homme dans son rapport à l’être à une pensée de l’être et de sa vérité dans son rapport à l’homme, comme Heidegger l’explique en 1962 au père Richardson. C’est à partir de là que se détermine ce que peut et doit être la pensée à venir, pensée qui, comme le dit la Lettre sur l’humanisme , « agit en tant qu’elle pense » en un faire inapparent et qui ne produit rien, mais qui est cependant plus haut que toute action et que toute production, parce qu’il est l’accomplissement de la projection (du déploiement de l’être en réponse à l’appel de celui-ci). Une telle pensée, qui n’est plus extérieure à ce qui est à penser, consiste à frayer la voie qui doit permettre le passage du premier commencement (grec) à l’autre commencement de la pensée.

➤ La tentative singulière des Contributions à la philosophie n’est peut-être en aucun lieu plus difficile qu’en ce qu’elle cherche à accomplir, dans la langue de Hölderlin, concernant Gott , Götter , Gottheit . Elle l’accomplit d’abord dans la section vii du « livre », qui doit penser le dernier dieu par rapport à mais surtout contre « ceux qui ont été », et surtout, parmi eux, le dieu chrétien. Le dernier dieu apparaît alors, dans son étrange conjonction avec l’« extrême » de la mort, comme celui qui envoie un signe, le signe de notre appartenance à l’Être. Ainsi s’édifie la figure anonyme d’un dieu « unique » et de son « passage », en son opposition frontale, irréductible, avec le Dieu unique du monothéisme. Un « seigneur » ou un « maître » est alors pensé contre un autre, une Herrschaft , maîtrise ou seigneurie, s’oppose à la Herrlichkeit du Dieu unique. Pour quel salut, alors, s’il en est encore un ?

➤ Dans les Beiträge zur Philosophie , Heidegger essaie de penser le « Gotthaftes (divin) » de façon radicalement autre par rapport à la métaphysique classique qui, en tant que theologia rationalis , avait déterminé Dieu comme l’« étant suprême ». Cette étude examine la pensée heideggerienne du Seinsbedürfnis (besoin de l’être) en contraste avec la pensée métaphysique de Dieu et cherche en même temps à mettre en évidence la signification du « dernier Dieu » dans le contexte de l’ajointement de la pensée relevant de l’histoire de l’être comprise par Heidegger comme le passage du « premier commencement » à l’« autre commencement ».

➤ Dans les Beiträge zur Philosophie , le terme heideggérien le plus important pour caractériser l’être de l’étant à l’époque de l’achè­vement de la métaphysique, est celui de Machenschaft, « machination ». L’auteur veut montrer ici que cette notion est fortement inspirée par le concept de « mobilisation » chez Ernst Jünger, au cœur du texte « Contribution à la question de l’être » de 1955 (GA 9), ainsi que des notes rassemblées dans le volume 90 de la Gesamtausgabe . Jünger livre, dans Der Arbeiter , une interprétation de la société comme une totalité pour laquelle l’augmentation de sa propre puissance, qui s’accomplit dans une mobilisation infinie et destructrice, constitue une fin en soi. Il fournit alors « l’optique » nécessaire pour comprendre l’étant, tel qu’il est interprété par Nietzsche, comme volonté de puissance.

Visual Outcomes of Optic Pathway Glioma Treated With Chemotherapy in Neurofibromatosis Type 1
Authors: José Patrícia , Couceiro Rita , Passos João , Jorge Teixeira Filipa 
Published: October 2021

Purpose:
To analyze the visual outcomes following chemotherapy for optic pathway glioma in children with neurofibromatosis type 1.

Methods:
This was a retrospective cohort study of 58 children with optic pathway glioma between 2003 and 2019. Best corrected visual acuity (BCVA) at diagnosis and at the last follow-up visit were analyzed. Correlation tests were performed to determine whether the final BCVA was predicted by the initial BCVA, initial Dodge stage, or retinal nerve fiber layer (RNFL) thickness stability. The first-line chemotherapy regimen included vincristine plus carboplatin (2003 to 2016) and vinblastine (since 2017).

Results:

Twenty-four children (41%) received chemotherapy. The median age at diagnosis was 3 years, and 61% of the children were female. From the first visit to the last follow-up visit, there was a statistically significant difference in mean BCVA in eyes in the no treatment group (
P
= .034) but not in eyes in the chemotherapy group (
P
= .824). A moderate and weak positive correlation was found (
r
= 0.58 and
r
= 0.29, respectively). At the last follow-up visit, BCVA remained stable in 73% and improved in 27% of eyes in the no treatment group, and BCVA worsened in 25%, remained stable in 62%, and improved in 13% of eyes in the chemotherapy group. At the last follow-up visit, BCVA and Dodge stage had a weak negative correlation (
r
= −0.06 and
r
= −0.17, respectively). A negative moderate correlation was identified between RNFL thickness and BCVA at the last follow-up visit (
r
= −0.48 in the no treatment group and
r
= −0.46 in the chemotherapy group).

Conclusions:
Children treated with chemotherapy had worse BCVA, although the treatment arrested the decline or improved BCVA in 75% of the patients with no major side effects.

Chlorhexidine Gluconate Bathing Program to Reduce Health Care–Associated Infections in Both Critically Ill and Non–Critically Ill Patients
Authors: Chapman Leigh , Hargett Lisa , Anderson Theresa , Galluzzo Jacqueline , Zimand Paul 
Published: October 2021

Background
Critical care nurses take care of patients with complicated, comorbid, and compromised conditions. These patients are at risk for health care–associated infections, which affect patients’ lives and health care systems in various ways.

Objective
To gauge the impact of routinely bathing patients with 4% chlorhexidine gluconate solution on the incidence of health care–associated infections in a medical-surgical intensive care unit and a postoperative telemetry unit; to outline the framework for a hospital-wide presurgical chlorhexidine gluconate bathing program and share the results.

Methods
A standard bathing protocol using a 4% chlorhexidine gluconate solution was developed. The protocol included time studies, training, monitoring, and surveillance of health care–associated infections.

Results
Consistent patient bathing with 4% chlorhexidine gluconate was associated with a 52% reduction in health care–associated infections in a medical-surgical intensive care unit. The same program in a postoperative telemetry unit yielded a 45% reduction in health care–associated infections.

Conclusion
A comprehensive daily 4% chlorhexidine gluconate bathing program can be implemented with standardized protocols and detailed instructions and can significantly reduce the incidence of health care–associated infections in intensive care unit and non–intensive care unit hospital settings.

Background Even though many types of stents have been tested in superficial femoral artery (SFA) and popliteal artery (PA), most of these devices have provided an unsatisfactory outcome, probably due their unsuitable anatomical and physiological characteristics. The Supera peripheral stent (Abbott Vascular, Santa Rosa, CA, USA) is a braided interwoven nitinol device specifically designed for treating atherosclerotic lesions of the femoro-popliteal segment. The aim of this multicenter retrospective study was to describe the effectiveness of Supera stents in the management of femoral-popliteal atherosclerotic lesions and to critically analyze our findings in the context of current and past literature. Design and methods In this study we enrolled only patients who satisfied the inclusion criteria: i) patients affected by chronic obstructive arterial disease (COAD) grade II, as per Rutherford classification; ii) patients treated with endovascular revascularization and Supera stent implantation in the femoro-popliteal axis. We retrospectively analyzed the Doppler Ultra-sound (US) follow- up at 12-24 and 36 months to detect the vascular occlusions. The primary patency, primary patency assisted and TLR were described statistically analyzed by survival analysis and the demographic data, clinical data, device safety following stenting were described as frequency and mean value. Results 105 endovascular procedures on 99 patients for femoro-popliteal stenting with Supera were performed in four Italian hospitals. The median follow-up was 39 months (range 6-72), with primary patency rate of 83.1%, 74.3% and 69.5% at 12, 24 and 36 months after the procedure. The primary patency assisted was 89.9%, 76.8% and 73.4% in the same period, while the freedom from TLR values were 92.7%, 91.5% and 89.5% at 12, 24 and 36 months after the procedure, respectively. The mortality rate recorded at 12 months from the Supera implantation was 2.8% (3 out of 99 patients enrolled). Conclusions Our data were in agreement with the current literature, showing the non-inferiority Supera stent in relation to the other stent available. Supera stent showed an excellent safety, effectiveness profile and high durability for the treatment of PAD patients with femoro-popliteal artery disease.
