Relationship between Successive Flares in the Same Active Region and SHARP Parameters
Authors: Ran Hao , Liu Ying D. , Guo Yang , Wang Rui 
Published: September 2022

Abstract
A solar active region (AR) may produce multiple notable flares during its passage across the solar disk. We investigate successive flares from flare-eruptive ARs, and explore their relationship with solar magnetic parameters. We examine six ARs in this study, each with at least one major flare above X1.0. The Space-weather HMI Active Region Patch (SHARP) is employed in this study to parameterize the ARs. We aim to identify the most flare-related SHARP parameters and lay foundation for future practical flare forecasts. We first evaluate the correlation coefficients between the SHARP parameters and the successive flare production. Then we adopt a Natural Gradient Boost (NGBoost) method to analyze the relationship between the SHARP parameters and the successive flare bursts. Based on the correlation analysis and the importance distribution returned from NGBoost, we select the eight most flare-related SHARP parameters. Finally, we discuss the physical meanings of the eight selected parameters and their relationship with flare production.
Signatures of Impact-driven Atmospheric Loss in Large Ensembles of Exoplanets
Authors: Chance Quadry , Ballard Sarah , Stassun Keivan 
Published: September 2022

Abstract
The results of large-scale exoplanet transit surveys indicate that the distribution of small planet radii is likely sculpted by atmospheric loss. Several possible physical mechanisms exist for this loss of primordial atmospheres, each of which produces a different set of observational signatures. In this study, we investigate the impact-driven mode of atmosphere loss via N-body simulations. We compare the results from giant impacts, at a demographic level, to results from another commonly invoked method of atmosphere loss, photoevaporation. Applying two different loss prescriptions to the same sets of planets, we then examine the resulting distributions of planets with retained primordial atmospheres. As a result of this comparison, we identify two new pathways toward discerning the dominant atmospheric-loss mechanism at work. Both of these pathways involve using transit multiplicity as a diagnostic, in examining the results of follow-up atmospheric and radial velocity surveys.

Les conditions de l’innovation en travail social inhérentes à l’approche centrée sur le DPA-PC
Authors: Deverchère Nelly 
Published: September 2022

Cet article se base sur les résultats d’un travail de recherche mené en 2016 sur la participation des personnes au sein des services publics d’action sociale du Département de la Gironde – collectivité ayant formé une partie de ses travailleurs sociaux à l’approche centrée sur le Développement du Pouvoir d’Agir des Personnes et des Collectivités (DPA-PC). Il cherche à démontrer en quoi cette approche est une forme actuelle d’« innovation en travail social », définie par Stéphane Rullac comme une solution pour articuler de nouvelles réponses du travail social tout en renforçant ses valeurs. Alors que « le travail social peine à faire valoir sa capacité à innover, du fait de son incapacité à la démontrer, et aussi en raison d’une certaine forme de répugnance à le faire » (Rullac, 2021, p. 145), cet article permet de saisir comment les travailleurs sociaux rencontrés détruisent et recréent dans leur activité professionnelle de nouvelles pratiques pour favoriser la participation des personnes accompagnées, et pour leur permettre ainsi de développer leur pouvoir d’agir.
Le chiffrement, ou l’apport de la cryptologie à la sécurisation du stockage, de la transmission et du traitement des données
Authors: Goubin Louis 
Published: September 2022

Le développement des techniques nécessaires au stockage, à la transmission et au traitement des données numériques crée un besoin de plus en plus aigu de sécurisation de ces données. La cryptologie, que l’on appelle souvent la science du secret, apporte des réponses solides, souvent des preuves mathématiques, à la question de la confidentialité des données, et par là même à la protection de la vie privée. Nous proposons ici une excursion à travers la problématique du chiffrement des données, depuis les principes cryptographiques de base jusqu’à des applications plus complexes nécessitant de pouvoir effectuer des calculs sur les données chiffrées. Des perspectives nouvelles s’ouvrent grâce à des techniques récentes ; l’un des grands défis à relever en la matière est d’arriver à articuler sécurité et conformité réglementaire, notamment lorsqu’il s’agit de chaînes d’approvisionnement dans l’industrie ou de plateformes mettant en œuvre une analyse parfois inquiétante des données personnelles de leurs utilisateurs.
L’enjeu des données pour la cyberdéfense
Authors: Danet Didier 
Published: September 2022

L’espace numérique est un champ de conflictualité, où la maîtrise des données est un enjeu dont l’importance ne fait que croître. En effet, contrairement à une vision trop répandue, la cyberdfense ne s’intéresse pas uniquement à la protection des systèmes d’information interconnectés (le contenant), mais s’intéresse tout autant à celle des contenus informationnels, dont les données forment la matière première. Mais si la maîtrise des données devient ainsi un enjeu central de la cyberdéfense, elle est rendue presque illusoire, notamment du fait de la « datafication » du monde, de la révolution numérique à l’œuvre et de nouvelles pratiques sociales affaiblissant la capacité de contrôle des États sur la production et la circulation des données. Dans cet article, nous suggérons d’approfondir deux pistes de réflexion : la première vise à mieux protéger les stocks de données qui sont en possession des institutions civiles et militaires, et la seconde à responsabiliser les acteurs dans la génération des flux de données.
De l’effet contrasté des crises sur les comportements de citoyenneté organisationnelle – Étude dans la filiale tunisienne d’un centre d’appel français
Authors: Ben Hassine Anissa , Fessi Safa , Berrazaga Imen 
Published: September 2022

Les comportements de citoyenneté organisationnelle (CCO), qui peuvent être définis comme des comportements non prescrits à l’avance pour la réalisation d’un travail donné, sont reconnus pour leurs effets bénéfiques aussi bien sur le fonctionnement général de l’organisation que sur les individus qui la composent. L’objectif de cette recherche est d’étudier si les crises modifient la nature et l’intensité de ces comportements. Pour cela, une étude a été menée auprès des téléopérateurs d’un centre d’appel international implanté en Tunisie, avant et pendant la période de la crise du Covid-19. La méthodologie, de type qualitatif, mobilise différentes techniques : la participation observante dans une phase préliminaire, les entretiens exploratoires pour étudier les CCO adoptés et les facteurs incitant/inhibant leur adoption, et la netnographie, utilisée pendant les deux temps de la recherche et particulièrement pendant la crise du Covid-19. Les résultats montrent que si la crise permet de renforcer les CCO envers les individus, en particulier l’altruisme envers les collègues, elle peut considérablement dégrader les CCO envers l’organisation. Le premier résultat s’expliquerait par un soutien organisationnel perçu comme faible au cours de la crise alors que le deuxième trouverait son origine dans la violation du contrat psychologique dont les prémisses se retrouvent dans la réaction de l’entreprise au cours des crises précédentes, en l’occurrence celle de la révolution tunisienne en 2011. Par ailleurs, nous préconisons que l’accompagnement des employeurs de leurs collaborateurs en période d’incertitude est nécessaire afin de renforcer leur engagement. Ceci peut se faire à travers des pratiques de GRH reflétant attention et bienveillance, un accompagnement psychologique et une communication interne transparente.

Authors: Costa Silva Alberto , Abreu-Mendes Pedro , Morgado Afonso , Dinis Paulo , Martins Silva Carlos 
Published: September 2022

Objective: Surgery is the treatment for male lower urinary tract symptoms (LUTS) relat-ed to benign prostatic obstruction (BPO) refractory to pharma-cological treatment or with complications. This study aimed to assess factors associated with the need for surgical reinterven-tion and/or continuation of pharmacological treatment. Materials and methods: A retrospective analysis of patients who underwent prostatic surgery for male LUTS associated with BPO between 1 May 2015 and 1 May 2016, with a minimum follow-up of ﬁve years, in an academic tertiary hospital. The type of surgery, preoperative, postoperative and follow-up analysis were collected in a database. Results: A total of 212 patients were included with a mean age of 70 ± 8.66 years at ﬁve years follow-up. At 5 years, a total of 86.9% of patients do not need pharmacological treatment and 12% required surgical reintervention. Of the preoperative parameters, it was found a relationship between prior prostatitis and the need for second surgery with an odds ratio of 4.6.
Conclusions: Patients should be informed of the potential need for pharmacological treatment following surgery, or even of the need for reintervention. History of prostatitis seems to be a risk factor for reintervention.

Authors: Bhat Maya , Natarajan Archana , Chandra SR , Christropher Rita , Netravathi M 
Published: September 2022

Abstract

Background and Objectives:
X-linked adrenoleukodystrophy (X-ALD) occurs due to the mutation in the ABCD1-gene. Our study was to correlate the clinical, radiological, and biochemical features in a cohort of X-ALD patients.

Methods:
We retrospectively analyzed 48 (M: F: 47:1) biochemically confirmed cases of X-ALD, classified them as cerebral ALD (childhood, adolescent, and adult), adrenomyeloneuropathy, Addisonian only. The Magnetic Resonance Imaging (MRI) of the radiological patterns was classified based on Loes classification.

Results:
The various clinical phenotypes were childhood cerebral X-ALD (58.3%), adolescent cerebral X-ALD (14.6%), adult-cerebral X-ALD (20.8%), Addisonian variant (4.2%), and adrenomyeloneuropathy (AMN) (2.1%). The imaging features were posterior white matter (Pattern-1) observed in 33 (68.75%) patients, cerebellar white matter (Pattern-4) noted in 5 subjects, anterior white matter (Pattern-2) observed in 3 patients, combined parieto-occipital and frontal white matter (Pattern-5) observed in 3 patients, isolated projection fiber (Pattern-3) observed in 1 patient. Rare features of the involvement of optic tract, anterior and lateral columns of cervicodorsal cord, bilateral central tegmental tracts, basal ganglia, and tigroid appearance were observed.

Interpretation:
This is a comprehensive clinical, biochemical, and imaging analysis with follow-up information of one of the largest series of X-ALD patients. The knowledge regarding the clinical features, typical and atypical imaging patterns is of vital importance for early diagnosis and treatment.

Published: September 2022

Abstract

Background:
The outcome in patients of atlanto-axial dislocation (AAD) depends on multiple factors like preoperative optimization, intraoperative distractio and cord manipulation. Certain unfocussed factors such as respiratory reserve and compensatory acclimatization to hypoxia warrant consideration.

Aims:
The purpose of this study is to find the association of postoperative arterial blood gas (ABG) analysis and respiratory reserve in patients of AAD with clinical outcome.

Study Design:
We retrospectively analyzed the available records of patients, operated for AAD, at our institute (n = 66), from January 2014 to November 2018.

Materials and Methods:
Preoperative pulmonary function test (PFT) and the postoperative ABG analysis was noted. Timing of extubation, duration of intensive care unit (ICU) stays, and clinical outcomes (Nurick grade) were noted from the inpatient record and the last outpatient follow up. An independent t-test and analysis of variance were used to find significance.

Results:
In total, 41% (n = 27) patients had body mass index of less than 18.5, and 50% (n = 33) had breath holding time of less than 20 minutes. There was improvement in mean Nurick grade from 3.17 ± 0.8 to 2.76 ± 0.7 in follow up. A trend suggesting that patients with poor preoperative PFT has more ICU duration and worse outcome. In patients with mild acid-base disorders, extubation was possible within 24 hours. Out of 26 patients with ICU duration less than 2 days, 23 patients had “good” outcome, whereas ten out of 40 patients with ICU duration of more than or equal to 2 days had “bad” outcome (P = 0.00).

Conclusion:
Patients having moderate to severe primary or mixed acid-base disorder have a probability of re-intubation or delayed extubation. A strong correlation was seen with the novel grading system (grade >6 had worse outcome).
Transcranial Magnetic Stimulation during Gait
Authors: Mate Kedar K. V. 
Published: September 2022

Abstract
Transcranial magnetic stimulation (TMS) is widely used for therapeutic and research purposes such as cognitive studies, treatment of psychiatric disorders, and Parkinson's disease. In research, TMS is perhaps the only technique that can establish a functional connection between brain regions and task performance. In gait research, often TMS is used to identify the extent to which leg motor cortex is involved in different phases on gait cycle. However, using TMS in gait can be challenging for several technical reasons and physiological variations. The objective of this narrative review is to summarize literature in the field of TMS and gait research and present comprehensive challenges. A comprehensive literature search was conducted in PubMed and Google Scholar to identify all relevant literature on TMS and gait. Several critical challenges could potentially impact the findings. For instance, the use of different protocols to obtain motor threshold. This review presents some of the critical challenges in applying TMS during gait. It is important to be aware of these variations and utilize strategies to mitigate some challenges.

Authors: Rissardo Jamir P. , Caprara Ana L. F. 
Published: September 2022

Abstract

Background/Objective:
Neurosyphilis can be associated with a variety of clinical manifestations. There are only a few cases of neurosyphilis associated with parkinsonism-plus syndromes (PPSs) that have been reported in the literature. We describe a case of an elderly woman who presented with abnormal gait and progressive visual disturbance, probably secondary to neurosyphilis.

Methods:
Literature search was performed in Embase, Google Scholar, Medline, Scielo, and ScienceDirect using a set of terms that included parkinsonism, tremor, and syphilis.

Case Report:
A 64-year-old female was admitted because of vision problems, gait disturbances, and cognitive impairment. The neurological examination revealed bradykinesia, rigidity, and rest tremor. The pupils were bilaterally small and reacted in size to a near object but did not constrict when exposed to bright light. The conjugate eye movements showed a defective downward gaze. On neuropsychological examination, the mini-mental state exam showed a moderate cognitive impairment. Reduced phonemic fluency was observed. A positive serum venereal disease research laboratory (VDRL) test was noted. A cerebrospinal fluid analysis showed positive VDRL. Brain and cervical spine magnetic resonance imaging was normal. An electro-encephalogram showed diffused slow waves. Penicillin G was started. Six months after, the patient had a full recovery of her conjugate eye movements and cognitive functions. Upon further questioning, the patient reported no response with a levodopa attempt.

Conclusions:
To the authors' knowledge, two individuals developed progressive supra-nuclear palsy (PSP), and one presented corticobasal degeneration (CBD), probably associated with neurosyphilis. This is the second case to document the occurrence of a progressive supra-nuclear palsy because of syphilis.

Abstract
The cerebellum is classically linked with control of motor function, such as coordination, balance, and regulation of movement. There is an increasing awareness, now, of the non-motor functions of the cerebellum, and the occurrence of behavioral anomalies with cerebellar disorders. We present the first report of Schmahmann syndrome (cerebellar cognitive affective syndrome [CCAS]) occurring secondary to posterior fossa meningioma excision. A 35-year-old lady with a posterior fossa meningioma developed an infarct of the right posterosuperior cerebellar hemisphere and ipsilateral superior vermis, following suboccipital craniotomy and tumor resection. Few days after the surgery, she presented with aggressive and emotional behavior, irrelevant talk, and emotional lability. The CCAS scale was administered, and she scored poorly on almost all parameters. A neuropsychological evaluation was also done. The occurrence of CCAS, posterior fossa syndrome (PFS), and behavioral abnormalities like abnormal pathological laughter/crying provides further clinical evidence of the “affective” functions of the cerebellum, modulated mainly by the posterior lobe and vermis of the cerebellum.

Abstract

Background:
Neuromyelitis optica (NMO) is an autoimmune demyelinating disorder, mainly characterized by severe optic neuritis, transverse myelitis and the high levels of antibodies against NMO-immunoglobulin G (IgG) or aquaporin-4 (AQP4). HLA-DR and HLA-DQ alleles within the HLA class II region on chromosome 6p21 are known to play a significant role in several autoimmune diseases including NMO. The rationale of the current case-control study is to explore the association of HLA-DRB1 and HLA-DQB1 alleles with the risk of NMO and its association with the clinical and serological markers.

Methods:
A total of 158 samples (38 NMO cases and 120-age and ethnicity matched controls) were genotyped for the HLA-DRB1 and HLA-DQB1 alleles by using PCR-SSP method.

Results:
Our analysis showed significant association of HLA-DRB1*10 allele (OR 2.63, 95% CI: 1.18-5.83, p=0.02) with NMO whereas DRB1*14 showed protective role against NMO (OR 0.33: 95% CI: 0.11-0.94, p=0.043). HLA-DRB1*10 allele also showed significant association in patients with NMO-IgG positive antibody (OR 3.28: 95% CI: 1.42-7.5, p=0.006). There was no association of HLA DQB1 alleles with NMO and also with NMO-IgG antibody. Among the haplotypes groups, HLA-DRB1*10-DQB1*05 (OR 2.61, 95% CI: 1.11-6.1, p=0.03), HLA-DRB1*15-DQB1*03 (OR 4.5, 95% CI: 1.81-11.5, p=0.001) were strongly associated with the risk of NMO, whereas DRB1*14-DQB1*05 (OR 0.20, 95% CI: 0.060-0.721, p=0.008) showed negative association with NMO.

Conclusion:
From this study, it is concluded that the HLA-DRB1*10 and DRB1*10-DQB1*05 and HLA-DRB1*15-DQB1*03 haplotypes may influence the susceptibility to NMO among the South Indians. Additionally we found DRB1*14 allele and DRB1*14-DQB1*05 haplotype showed protective role for NMO.
