Abstract
We report on the commensal ASKAP detection of a fast radio burst (FRB), FRB 20211127I, and the detection of neutral hydrogen (H i) emission in the FRB host galaxy, WALLABY J131913–185018 (hereafter W13–18). This collaboration between the CRAFT and WALLABY survey teams marks the fifth, and most distant, FRB host galaxy detected in H i, not including the Milky Way. We find that W13–18 has an H i mass of M
HI = 6.5 × 109
M
⊙, an H i-to-stellar mass ratio of 2.17, and coincides with a continuum radio source of flux density at 1.4 GHz of 1.3 mJy. The H i global spectrum of W13–18 appears to be asymmetric, albeit the H i observation has a low signal-to-noise ratio (S/N), and the galaxy itself appears modestly undisturbed. These properties are compared to the early literature of H i emission detected in other FRB hosts to date, where either the H i global spectra were strongly asymmetric, or there were clearly disrupted H i intensity map distributions. W13–18 lacks a sufficient S/N to determine whether it is significantly less asymmetric in its H i distribution than previous examples of FRB host galaxies. However, there are no strong signs of a major interaction in the optical image of the host galaxy that would stimulate a burst of star formation and hence the production of putative FRB progenitors related to massive stars and their compact remnants.
Massive Protostellar Disks as a Hot Laboratory of Silicate Grain Evolution
Authors: Yamamuro Ryota , Tanaka Kei E. I. , Okuzumi Satoshi 
Published: May 2023

Abstract
Typical accretion disks around massive protostars are hot enough for water ice to sublimate. We here propose to utilize the massive protostellar disks for investigating the collisional evolution of silicate grains with no ice mantle, which is an essential process for the formation of rocky planetesimals in protoplanetary disks around lower-mass stars. We, for the first time, develop a model of massive protostellar disks that includes the coagulation, fragmentation, and radial drift of dust. We show that the maximum grain size in the disks is limited by collisional fragmentation rather than by radial drift. We derive analytic formulae that produce the radial distribution of the maximum grain size and dust surface density in the steady state. Applying the analytic formulae to the massive protostellar disk of GGD27-MM1, where the grain size is constrained from a millimeter polarimetric observation, we infer that the silicate grains in this disk fragment at collision velocities above ≈10 m s−1. The inferred fragmentation threshold velocity is lower than the maximum grain collision velocity in typical protoplanetary disks around low-mass stars, implying that coagulation alone may not lead to the formation of rocky planetesimals in those disks. With future measurements of grain sizes in massive protostellar disks, our model will provide more robust constraints on the sticking property of silicate grains.
New Jupiter and Saturn Satellites Reveal New Moon Dynamical Families
Authors: Sheppard Scott S. , Tholen David J. , Alexandersen Mike , Trujillo Chadwick A. 
Published: May 2023

Abstract
Tens of new moons around both Jupiter and Saturn have been announced on Minor Planet Electronic Circulars (MPECs) in late 2022 and early 2023. Jupiter now has 95 and Saturn 146 confirmed moons. Many smaller and fainter moons have also been detected at these planets but not yet confirmed through MPECs. These discoveries nearly complete the small moon population of Jupiter to about 2 km and Saturn to about 3 km and show new dynamical satellite families. The once lone Carpo is now joined by S/2018 J4, making it a group of two small prograde moons around Jupiter. The Inuit prograde family around Saturn appears to be 3 distinct groupings. S/2004 S24 seems to be a unique distant small Saturn prograde moon, as could be S/2006 S12 and S/2019 S6. S/2006 S20 might be the first found member of a compact Phoebe Saturn moon family.

L’argent liquide n’en finit pas de disparaître du quotidien. Les pièces et les billets, qui constituent encore la forme de référence de l’argent dans les imaginaires, s’effacent peu à peu des gestes ordinaires : payer, donner, recevoir, prêter, partager, mettre de côté et compter. L’article décrit les grandes dimensions de cette numérisation de l’argent, elles ont trait au développement de monnaies intrinsèquement numériques, à l’apparition de nouveaux intermédiaires de paiement et aux innovations du paiement mobile. Il identifie ensuite des axes de recherche pour penser ces transformations. Le reflux de l’argent liquide et l’avènement annoncé de sociétés cashless , les données de l’argent et du paiement, et l’appropriation de l’argent numérique sont l’objet d’investissements disparates par les sciences sociales que l’article cartographie.
L’argent liquide digital
Authors: Pucheu David 
Published: May 2023

Cette contribution propose d’interroger les racines idéologiques des cryptomonnaies à travers l’exploration de la liste de diffusion de la communauté virtuelle des cypherpunks. Réunis autour d’un noyau dur de hackers californiens, les cypherpunks ont esquissé les premiers projets de digital cash visant à doter les individus de moyens de transaction en ligne à la fois anonymes, intraçables et infalsifiables qui ont donné naissance aux cryptomonnaies. Inscrit dans un vaste projet de réformation sociale aux accents utopiques et informés par les courants radicaux de l’économie politique libertarienne, l’argent liquide digital constituait pour ses instigateurs le héraut d’une nouvelle ère, celle de la « crypto-anarchie ». Assimilant indistinctement les interactions sociales et économiques en ligne à une forme de liberté d’expression individuelle sur laquelle les États et les grandes corporations ne pourraient plus exercer aucune emprise, les cyberpunks ont inventé les protocoles cryptographiques destinés à actualiser leur vision. Une vision aujourd’hui nuancée par le déploiement de ces innovations dans le Nouveau Monde industriel du capitalisme digital.
Numérisation, normalisation et institutionnalisation d’une monnaie locale
Authors: Fois Duclerc Mathilde 
Published: May 2023

Depuis 2010, des dizaines de monnaies locales ont été créées en France, d’abord sous forme de coupons de papier. Désormais, certaines circulent aussi sous forme numérique. L’article se fonde sur le cas de l’eusko, créé au Pays basque en 2013 et qui s’est doté d’une forme numérique en 2017. À partir d’une enquête ethnographique au sein de l’association Euskal Moneta « la monnaie basque », l’article retrace les principales étapes de l’introduction de moyens de compte et de paiement numériques. L’article analyse le rôle de ce processus de numérisation dans l’institutionnalisation de la monnaie locale. Nous montrons qu’il opère une double normalisation de la monnaie, par l’ajustement de son fonctionnement aux usages communs de l’argent et par une certaine reconnaissance des outils numériques par les autorités de régulation du secteur bancaire. Cette entrée marginale dans le secteur des services de paiement s’accompagne, chez les responsables de la monnaie, d’un travail visant à conserver l’ancrage militant de la monnaie et la nature de son projet politique.

Authors: Karam Mohammad , Alsaif Abdulmalik , Kahlar Narvair , Hayre Amrit , Vyas Neel , Ekitok Sophie-Rose , Gan Weh Loong , Al-Hity Aws 
Published: May 2023

Background and Objectives:
This study aims to compare the outcomes of pneumatic retinopexy (PnR) versus pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD).

Materials and Methods:
A systematic review and meta-analysis were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. An electronic search was conducted identifying six comparative studies of PnR versus PPV for RRD enrolling 1,061 patients. The primary outcome was visual acuity (VA). Anatomical success and complications were the secondary outcomes.

Results:

No statistically significant difference was observed in VA between the groups. There was a statistically significant difference in the odds of re-attachment favoring PPV over PnR (odds ratio [OR] = 0.29,
P
< 0.00001). No statistically significant difference was found in final anatomical success (OR = 1.00,
P
= 1.00) and the development of cataracts (OR = 0.34,
P
= 0.61). Other complications, including retinal tears and postoperative proliferative vitreoretinopathy, were more frequently reported in the PnR group.

Conclusion:
PPV has a higher rate of primary reattachment compared to PnR for treating RRD with comparable final anatomical success, complications, and VA outcomes.

Influence of whitening additives on the properties of decorative slag-alkali cements and mortars
Authors: Krivenko P. , Puertas F. , Gots V. , Helevera O. , Rogozina N. 
Published: May 2023

The paper shows a comparative study of the influence of whitening additives (kaolin, TiO2 and СаСО3) on the production of decorative alkali-activated slag cement and mortars with a degree of whiteness of at least 70%; as well as their influence on the structure formation and evolution of physico-mechanical properties. According to results obtained, kaolin provides chemical bonding of Na+ into insoluble zeolite-like compounds; and CaCO3 densifies the structure and reduces shrinkage deformations. At the early stages of hardening (up to 7 days), the additions of kaolin and calcite, due to their significant amount (15 and 24%), reduces the compressive strength of the cement paste; nevertheless, at later ages (until 90 days) the difference in strength almost disappears. The high colourfastness and weather resistance of pigmented cements under the influence of ultraviolet radiation and freeze/thaw cycles has been established. A comparative assessment of the economic efficiency has shown that СаСО3 is the best cost-effective additive.
Transcriptomic profiling and classification of skin melanoma based on ultraviolet response
Authors: Xiao* Dongxing , Guo Zhaozhao , Xiong Yuzhen , He Xinqiang , Zhao Chong , Tang Ni 
Published: May 2023

Background:
We aimed to explore the therapeutic biomarker for cutaneous melanoma (CM).

Objectives:
The objective is to provide a novel direction for improving overall survival (OS) for CM.

Methods:
We obtained the gene sets related to ultraviolet (UV) reaction from MsigDB database and CM HTSeq-FPKM data from The Cancer Genome Atlas (TCGA). Gene set variation analysis was used to calculate the enrichment scores in each sample. DAVID and Gene Set Enrichment Analysis (GSEA) were used to explore the function of differentially expressed genes (DEGs) between cluster 1 and cluster 2. The ssGSEA was used to analyze the degree of immune infiltration in samples. Weighted gene co-expression network analysis (WGCNA), protein–protein interaction (PPI) network, and mutation analysis were performed to screen the DEGs related to UV response.

Results:
The samples were divided into the high activity of UV response (cluster 1) and low activity of UV response (cluster 2). We found that cluster 2 was related to poorer OS and had a higher reaction to UV response. Function analysis indicated that the DEGs are involved in angiogenesis, epidermal development, and inflammatory reaction. Furthermore, the cluster 2 had a higher degree of immune infiltration. The results of WGCNA indicated that the genes in the MEyellow module were highly related to UV response, which is involved in the process of angiogenesis, cell migration, and skin development. PPI and mutation analysis indicated that COL5A1 was the risk factor for CM.

Conclusion:

COL5A1 might be an important biomarker and potential therapeutic target of CM.
Bart Syndrome
Authors: Trivedi Madhvi , Mehta Rajesh Dutt , Ghiya Bhikam Chand , Soni Prasoon 
Published: May 2023

Background:
Bart syndrome is one of the rarest forms of aplasia cutis congenita (ACC).

Clinical Description:
We report a sporadic case of a neonate presenting with the absence of skin on the lower limb, tense blisters on fingers, and nail dystrophy.

Management:
Clinical features and skin biopsy confirmed the diagnosis of Bart syndrome. The baby was given symptomatic treatment with regular antimicrobial dressing. Within 2 weeks, the defect healed with the formation of hypopigmented scar and milia. The bullous lesions also disappeared completely.

Conclusion:
Bart syndrome, which is a type of ACC, is an extremely rare occurrence. Although it has an extensive involvement, the lesions if superficial, limited to the epidermis, have a good prognosis. Conservative management is sufficient to cause healing within a short span of time.
Rapid-Onset Obesity with Hypoventilation, Hypothalamic Dysfunction, and Autonomic Dysregulation Neuroendocrine Tumor Syndrome
Authors: Mondal Anurag , De Hriday , Ghosh Apurba , Pal Priyankar , Biswas Debapoma 
Published: May 2023

Background:
Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHAD) syndrome is a rare cause of obesity, characterized by early and rapid onset of obesity, hypoventilation, hypothalamic dysfunction, and autonomic dysfunction. When there is an associated neuroendocrine tumor, (NET) it becomes ROHHAD NET. Hypothalamic dysfunction causes endocrine problems, respiratory dysfunction, and autonomic alterations. It is difficult to distinguish this clinically from other obesity syndromes of genetic origin unless an individualized strategic approach is used.

Clinical Description:
We present a case of a 5-year-old developmentally normal girl with excessive weight gain starting in early childhood and the development of a squint. The clinical phenotype of central hypoventilation and autonomic dysfunction, central hypothyroidism, and central precocious puberty satisfied the criteria for ROHHAD syndrome.

Management:
A right-sided paraspinal supradiaphragmatic mass was identified that was excised and diagnosed as neuroblastoma on histopathology. Since there was no evidence of metastases, chemotherapy was not indicated. Alpha and beta-blockers were started for autonomic dysfunction and high catecholamine levels. Lack of improvement in behavioral manifestations prompted a trial of immunosuppressive therapy, but yielded no results. She ultimately succumbed to a probable cardiorespiratory arrest during sleep.

Conclusions:
ROHHAD syndrome should be considered a differential diagnosis in rapid-onset monogenic obesity and should be managed with a multidisciplinary approach. Prognosis is guarded due to sudden life-threatening events secondary to autonomic dysfunction.
Rare Coexistence of SLC6A9 and TOR1A Gene Mutations in a Neonate Presenting with Hereditary Hyperekplexia and Arthrogryposis Multiplex Congenita
Authors: Patel Bhavya , Bhatt Shwetal , Chanpura Vaishali 
Published: May 2023

Background:Neonatal hyperekplexia is a rare nonepileptiform disorder characterized by an exaggerated startle reflex associated with generalized hypertonia. We report a newborn with mutation in the glycinergic inhibition pathway resulting in hyperekplexia, associated with features of arthrogryposis multiplex congenita.Clinical Description:A 3-day-old newborn born at term vaginally cried immediately after birth and presented with lethargy, poor cry, and abnormal clonic movements of all four limbs. On examination, there was hyperreflexia and hypertonia in all four limbs along with dislocation of the right knee joint. Blood investigations, including tandem mass spectrometry, serum ammonia, serum, and cerebrospinal fluid glycine levels, were normal, ruling out inborn errors of metabolism responsible for hyperekplexia and arthrogryposis. The magnetic resonance imaging (MRI) brain and electroencephalogram were normal, while the MRI spine showed kyphosis. The genetic evaluation showed heterozygous missense mutation in exon 6 of the SLC6A9 gene and homozygous mutation in the TOR1A gene, which explained the hyperekplexia and the arthrogryposis multiplex congenita.Management and Outcome:The patient received supportive care. Oral clonazepam and levetiracetam were started in view of hypertonia and clonic spasms. Feeding was given by intragastric tube as he had poor suck–swallow coordination.Conclusions:This case highlights an interesting and extremely rare combination of hereditary hyperekplexia and arthrogryposis multiplex congenita existing together in the same patient, confirmed by the corroborating genetic mutations. Awareness of such conditions among pediatricians is essential to order appropriate genetic evaluations and treatment accordingly.
Optic Nerve Demyelination Along with Cardiorespiratory Involvement
Authors: Muduli Jayant Kumar , Mitra Meenakshi , Mahipal Shivam 
Published: May 2023

Background:
Multisystem inflammatory syndrome in children (MIS-C) has been described as an illness consisting of inflammation of more than one system of the body with raised inflammatory biomarkers following an infection of COVID-19. There is growing literature regarding the clinical spectrum of the condition. We report an unusual presentation of optic nerve demyelination in a child diagnosed with MIS-C.

Clinical Description:
A 3 years, 10-month-old boy presented with fever, generalized maculopapular rash, conjunctivitis, and bilateral palmar erythema. On examination, the child was febrile with tachypnea, tachycardia, and engorged jugular veins. Chest auscultation revealed basal crepitation. The cardiovascular examination was unremarkable. He had tender hepatomegaly. He developed photophobia and poor vision on the fourth day of admission with weakness of limbs. Ophthalmological examination showed a loss of visual acuity (perception of light only), while the fundoscopy examination was normal.

Management:
Inflammatory biomarkers and COVID-19 antibody titers were elevated. Echocardiography (ECHO) showed dilatation of the coronary arteries and poor ejection fraction. Magnetic resonance imaging of the brain showed bilateral optic nerve demyelination. Thus, the diagnosis was consistent with MIS-C with optic neuritis. Treatment was initiated with intravenous immunoglobulin (IVIG) and intravenous methylprednisolone with other supportive measures. At the 3-week follow-up, the child's vision, power in all four limbs, and echo parameters improved.

Conclusion:
This case creates awareness regarding optic neuritis as a rare presentation of MIS-C with cardiorespiratory and neurological involvement, successfully managed with IVIG and steroids.
Genotype–Phenotype Characteristics of Children with Distal Renal Tubular Acidosis Caused by WDR72 Mutations
Authors: Todkar Mugdha , Harshitha S , Bhatt Girish Chandra 
Published: May 2023

Background:
Distal renal tubular acidosis (dRTA) can be acquired or inherited. Hereditary types of dRTA are mostly seen in the pediatric population, whereas acquired forms predominate in adults. The diagnosis of hereditary dRTA can be confirmed by genetic testing. Five genes are known to cause the disease: ATP6V1B1, ATP6V0A4, FOXI1, SLC4A1, and WDR72. Most of the children with autosomal dominant forms carry mutations in the SLC4A1 gene, whereas the most common mutation in autosomal recessive type is ATP6V0A4 and ATP6V1B1 genes.

Objective:
In this systematic review of case reports, we discuss the clinical features and mutation variants of hereditary dRTA due to homozygous pathogenic variations in the WDR72 gene, which has been recently identified.

Methods:
The PubMed and Google Scholar databases were searched with defined search terms and eligibility criteria independently by different authors.

Results:
Of five full-text articles retrieved, four were finally included which provided data of 14 individuals, all of which had specific mutations in WDR72 gene. The majority of cases were attributed to individuals of Asian descent (71%) with equal distribution of males and females. The mean age of onset was 4.42 years. Amelogenesis imperfecta (AI) was described in 90% of patients, nephrocalcinosis in 62.5%, polyuria in 55.5%, proximal muscle weakness in 55.5%, and rickets in two patients.

Conclusion:
In patients exhibiting features such as metabolic acidosis, hypokalemia, AI, polyuria, nephrocalcinosis, and growth retardation, genetic analysis for WDR72 mutation should be considered.
Congenital Chylothorax with Cytomegalovirus Positivity
Authors: Jain Yash , Jain Shivani , Jain Jenisha , Sharma Minakshi 
Published: May 2023

Background:
Nonimmune hydrops fetalis (NIHF) due to congenital chylothorax (CC) is rare and is usually associated with high mortality. Chylothorax complicated with congenital cytomegalovirus (CMV) infection is extremely rare and the management becomes challenging. We present a case of CC in a preterm infant with associated CMV positivity, which was managed successfully.

Clinical Description:
A 2.25 kg, 34-week female newborn, with antenatally diagnosed hydrops, delivered by emergency cesarean section, presented with pleural effusion and poor respiratory efforts.

Management:
The baby was provided mechanical ventilation and all supportive treatments. Pleural fluid testing was suggestive of high proteins with high white cell counts, predominantly lymphocytes. Baby was also positive for CMV immunoglobulin M with a high number of copies in the urine polymerase chain reaction. The baby initially responded well to oral valgancyclovir but returned with severe respiratory distress on day 20 of life, at which time, was again found to have right-sided chylothorax. This was managed successfully with octreotide at a dose of 8 μg/kg/hour and 90% medium chain triglyceride diet.

Conclusions:
CC should be considered in the differential diagnosis of NIHF. An incidental serological test positivity for CMV may be superimposed on underlying CC. If the latter is managed optimally with close monitoring, the outcome is usually favorable.
