We have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, P
out, of only 24.5 days. This “eclipses” the previous record set by λ Tauri at 33.02 days, which held for 68 yr. The inner binary, with an orbital period of P
in = 1.8 days, produces primary and secondary eclipses and exhibits prominent eclipse timing variations with the same periodicity as the outer orbit. The tertiary star eclipses, and is eclipsed by, the inner binary with pronounced asymmetric profiles. The inclinations of both orbits evolve on observable timescales such that the third-body eclipses exhibit dramatic depth variations in TESS data. A photodynamical model provides a complete solution for all orbital and physical parameters of the triple system, showing that the three stars have masses of 6.85, 6.11, and 7.90 M
⊙, radii near those corresponding to the main sequence, and T
eff in the range of 21,000–23,700 K. Remarkably, the model shows that the triple is in fact a subsystem of a hierarchical 2+1+1 quadruple with a distant fourth star. The outermost star has a period of ∼3200 days and a mass comparable to the stars in the inner triple. In ∼20 Myr, all three components of the triple subsystem will merge, undergo a Type II supernova explosion, and leave a single remnant neutron star. At the time of writing, TIC 290061484 is the most compact triple system and one of the tighter known compact triples (i.e., P
out/P
in = 13.7).
Breakaway from a globular body shape: molecular phylogeny reveals the evolutionary history of the enigmatic springtail Mackenziella psocoides
Authors: Schneider Clément , D’Haese Cyrille A.
Published: October 2024

Mackenziella psocoides Hammer, 1953 (Collembola: Mackenziellidae) is a widespread but uncommon springtail. Its unusual body shape (ovoid, with partial coalescence of abdominal segments) has puzzled the specialists for a long time, until the discovery of males allowed to relate the species to a family of globular springtails, the Sminthurididae. Yet, the precise phylogenetic position of M. psocoides, and hence of the Mackenziellidae, remained ambiguous. In this work, we report a new locality for M. psocoides in Germany. We provide the first DNA sequences (nuclear ribosomal DNA operon) for the species, as well as the first images using scanning electron microscopy. We investigate its phylogenetic position based on the molecular data and specify details on its morphology. Our results show that M. psocoides is nested inside of Sminthurididae, as the sister group of Sphaeridia Linnaniemi, 1912. Consequently, Mackenziellidaesyn. nov. is here synonymized with Sminthurididae. We include Mackenziella and Sphaeridia in the Sphaeridiainaesubfam. nov., a replacement name for Sphaeridiinae Richard, 1968 that is a junior homonym of Sphaeridiinae Latreille, 1802 (Coleoptera: Hydrophilidae). Corresponding to its phylogenetic position within Sminthurididae, the evolutionary origin of M. psocoides is younger than previously thought (79 mya +/- 35 my). The lineage accumulated an unusual amount of body modifications involving, among others, the loss of the globular body shape. This rapid rate of evolution is, to our knowledge, unique in springtails. It shows that globular body shape is not an evolutionary dead-end, and the secondary acquisition of a linear body shape and recovery of longitudinal flexibility is still possible.

Published: October 2024

Palm fungi are a diverse and unique group mostly found on Arecaceae hosts. They have been studied for approximately 200 years resulting in a large number of known fungal species representing over 700 genera. The timeline of palm fungal studies could be roughly divided into three phases, based on the methods and frequency of reports. They are the “Historical palm fungi era”, “Classical palm fungi era” and “Molecular palm fungi era”. In the first two periods, the identification of palm fungi was based on morphology, which resulted in a considerable number of morphological species scattered across the data in books, monographs and papers. With the advancement of molecular techniques, studies on palm fungi accelerated. A large number of new species were introduced in the molecular era, especially from Asia, including China and Thailand. However, there is a necessity to link these three generations of studies into a single platform combining data related to host factors, geography and utilisation. Herein, we introduce the palm fungi website: https://palmfungi.org, an integrated data platform for interactive retrieval, based on palm and fungal species. This website is not only a portal for the latest, comprehensive species information on palm fungi, but also provides a new platform for fungal researchers to explore the host-specificity of palm fungi. Additionally, this study uses palmfungi.org and related data to briefly discuss the current status of research on the distribution of palm fungi populations, showing how palmfungi.org links fungi with their palm hosts. Furthermore, the website will act as a platform for collaboration amongst taxonomists, plant pathologists, botanists, ecologists and those who are interested in palms and their relationship with ecological sustainability.
Chlorocillium sinense sp. nov. (Clavicipitaceae) and Calcarisporium guizhouense sp. nov. (Calcarisporiaceae) in Hypocreales from China
Authors: Chen Wan-Hao , Li Dan , Liang Jian-Dong , Ren Xiu-Xiu , Zhao Jie-Hong , Han Yan-Feng
Published: October 2024

Two new species, Chlorocillium sinense and Calcarisporium guizhouense, isolated from a spider and fruiting body of Cordyceps sp., are introduced. Morphological comparisons and phylogenetic analyses based on multigene datasets (ITS+LSU+RPB2+tef-1alpha) support the establishment of the new species. A combined dataset of ITS, LSU, RPB2, and tef-1alpha showed the taxonomic placement of Chlorocillium in Clavicipitaceae for the first time. Pseudometarhizium is regarded as a synonym of Chlorocillium and two Pseudometarhizium species are transferred into the latter based on the phylogenetic analysis and morphological characteristics.
Reflections on Reproductive Justice in the United States from 1989 to 2024
Authors: Simmonds Katherine
Published: October 2024

In 1994, Women of African Descent for Reproductive Justice came together to give voice and vision to the term Reproductive Justice (RJ) and its principles in anticipation of the International Conference on Population and Development and in response to the reproductive rights movement in the United States that white and wealthy women dominated at that time. As a nurse who has worked on the front lines, sidelines, and behind the scenes over the three decades since that auspicious gathering, this article relays some of my professional experiences as they relate to what I believe are among the most pressing issues we face as a global community and as nurses striving to manifest the principles of RJ. The article ends with a call to action for nurses, as there is no time to waste.

Patients and Healthcare Professionals’ Perceptions of Stethoscope Barriers
Authors: Siegmund Lee , Peacock Frank , Bena James , Morrison Shannon
Published: October 2024

Stethoscope hygiene is rarely performed despite evidence that they are a potential source of nosocomial infections. Aseptic touch-free disposable stethoscope diaphragm barriers (touch-free barriers) provide a bacteriologically impervious surface; however, little is known about perceptions of touch-free barriers. The purpose of this study was to determine patients’ and healthcare professionals’ perceptions of stethoscope hygiene habits, cleanliness, and patient safety, after respondents viewed videos of stethoscope hygiene with alcohol versus a touch-free barrier, or no hygiene/no barrier. We conducted a cross-sectional study using survey methodology and convenience sampling. Participants viewed three short videos that showed a provider using each of three stethoscope hygiene techniques (barrier, alcohol, or none), followed by completion of a brief survey. Pearson’s chi-square, Fisher’s exact, Wilcoxon rank sum or Kruskal-Wallis tests were used as appropriate. Bonferroni correction was used to control error rate at 0.05 for each question. The sample size of 240 participants included 119 patients and 121 healthcare professionals. Patients rarely witnessed healthcare professionals cleaning stethoscopes, rated clean stethoscopes as important, and were more likely to choose touch-free barrier as easiest for providers. Healthcare professionals rated stethoscope hygiene as important, reported frequent stethoscope hygiene, and felt that touch-free barrier would improve workflow. Touch-free barriers were viewed positively by respondents. Hospitals should consider touch-free barriers as an important strategy to reduce nosocomial infections.
Advance Directives and the LGBTQ+ Population: Preparing Nurses for Practice
Authors: Miller Blanca , Reitz Erin , Rice Matt
Published: October 2024

The LGBTQ+ population encounters barriers related to advance directive completion in healthcare settings. Nursing curricula lack advance directive education specifically related to the challenges faced by the LGBTQ+ population. Nurses’ lack of understanding of these issues can impact informed end-of-life care choices. Nursing programs must improve advance directive education to prepare students for practice. Active learning and application strategies will provide students with opportunities to understand advance directives and the unique needs of the LGBTQ+ population. Practicing nurses must be able to advocate for LGBTQ+ persons when making informed end-of-life decisions and help them navigate barriers that may arise at the end of life. This article discusses the unique needs of the LGBTQ+ population and presents case examples to illustrate the barriers faced by LGBTQ+ people related to advance directives.

Published: October 2024

Un adolescent, en analyse depuis plusieurs années pour des rituels obsédants, a écrit et publié à compte d’auteur un « roman ». La mise en regard de la clinique de la cure et du texte révèle celui-ci comme le prolongement symptomatique d’une mélancolie plutôt qu’une « sublimation passagère » de l’adolescence.
Rock et cinéphilie : publics de niche et usages du rock dans le cinéma d’auteur
Authors: Bento Ribeiro Ana
Published: October 2024

Au fil de l’histoire, des cinéastes reconnus en tant qu’ « auteurs » utilisent les codes visuels et sonores du rock dans leurs récits filmiques. Ce style musical est ainsi au centre d’une culture cinématographique de niche. Cet article s’intéresse à la question suivante : de quelle manière le cinéma d’auteur s’approprie l’univers du rock dit « alternatif » en construisant des récits à la fois esthétiques, politiques et sociaux très appréciés d’une communauté de fans de cinéma et de musique. On analyse ici les intersections entre rock et cinéma d’auteur, en se penchant sur les collaborations artistiques entre cinéastes et musiciens. Notre discussion s’appuie sur les débats autour de la cinéphilie (De Baecque 2003), du rock et de la performance filmique (Palmer 2020), et des sous-cultures (Hebdige 1979).

Authors: Le Cam Florence , Vidalenche Alexia , de Valeriola Sébastien , Libert Manon , Deseure Brecht
Published: October 2024

À partir d’une analyse de corpus massifs de presse, cet article détaille le processus méthodologique alliant méthodes en humanités numériques et analyses qualitatives pour retracer la carrière d’une journaliste belge, Alice Bron. La recherche mène à dé-assigner Alice Bron de son seul rôle de femme, d’épouse, de bourgeoise. L’étude montre ainsi la densité de la carrière d’Alice Bron dans et hors des journaux au travers de l’analyse de sa médiatisation contrastée, des modes de dénomination dont elle a été l’objet et des formes d’assignation professionnelle genrée visibles dans la presse de l’époque. In fine, elle interroge les différentes mises en visibilité de ses identités publiques, professionnelles et personnelles et explore les rapports entre militantisme, féminisme et journalisme.
Hantologie musicale : la question de la mémoire dans les arts audio
Authors: Zénouda Hervé
Published: October 2024

L’hantologie musicale s’interroge sur le fonctionnement de la mémoire et la place de la captation sonore dans ce processus. L’adossement à une référence culturelle « savante » (Derrida) pour un courant musical expérimental populaire est à souligner. Il permet de réunir des musiciens venus d’horizons différents reliés entre eux non pas par des esthétiques sonores communes mais bien par un questionnement philosophique fondateur. L’anthologie musicale exemplifie ainsi l’effritement des frontières entre genres esthétiques mais aussi entre sphères culturelles différentes (savant/populaire). Elle célèbre de manière originale, dans un dernier soubresaut nostalgique, la fin de la « parenthèse indicielle » des médias analogiques.
Representations of Motherhood and Mothering in Popular Sinhala Lullabies
Authors: Embogama Sumudu
Published: October 2024

Popular Sinhala lullabies passed down orally from generation to generation occupy an ambiguous and neglected space within Sri Lankan music. Nonetheless, when examined closely, these lullabies offer rich and nuanced interpretations of female experiences, particularly concerning motherhood and mothering. These songs either reinforce or challenge patriarchal concepts within their intertextual frameworks. The primary aim of this study was to conduct a feminist critical discourse analysis of selected Sinhala lullabies to explore how they portray the dilemmas faced by women who are mothers or who aspire to be, caught between traditional expectations and the realities of becoming biological mothers. The findings demonstrate how these lullabies capture the complexities of Sinhalese women's experiences, reflecting their frustrations, emotional and physical suffering, and joyful connections with their children. Although the singers of these lullabies remain anonymous, their voices continue to critically engage with societal ideals and standards, revealing the multifaceted nature of mothering and motherhood within the Sinhala community.
Study of Musicality in the Recitation of Religious Hymns
Authors: Sujatha T. K. L.
Published: October 2024

Religious traditions across the globe have their unique ways of reciting sacred hymns based on different melodic structures. Whether it is the chanting of Veda mantras in Hinduism or the recitation of Salaah in Islam or the singing of psalms in Christianity, there is a melodic flow in these hymns. Hymns have their own melodic appeal that makes them stand out among various melodic compositions, regardless of their language. The objective of this paper is to study the musicality of different religious hymns by selecting a few hymns from different traditions. This paper limits its study to the musical aspects of the oral traditions of reciting sacred hymns of different religions and it attempts to explore the unique musical elements in these hymns and also offers an insight into the artistic expressions across different religious cultures, through their musical recitations. Audio samples of the hymns are collected from various sources including field recordings, online resources and interviews. The collected data is subject to musical analysis by giving notations to the selected audio samples using musical notes of the Indian system of music, analyzing tonal variations and vocal techniques, and comparing the musical features to study the similarities and distinctions. The results of the analysis include finding the musical phrases from the chanting of different hymns, listing the observed commonalities and differences, and realizing the limited scope of melody. Eventually, the study accentuates the power of the musical notes, even with limited combinations, in building an effective auditory impact. These findings have significant implications on understanding the role of music in diverse religious traditions. This in turn results in establishing the fact that music has been an integral part of religious practices which takes it beyond the level of entertainment.

Published: October 2024

This research paper discusses the complexity of performing, emphasising one’s traditional arts and belongings to claim and represent one's cultural capital or to meet the stereotypical anticipations of ‘others’ in shared cultural spaces, particularly in the context of sociocultural parades. This research also briefly delves into how the dynamics of disempowerment and empowerment of subcultures affect representing identities in shared spaces. It employs archival observations to analyse the Ruhunu Katatharagama Dewala Asala Perehera procession in Sri Lanka. In particular, the study exemplifies the representation of the identities of the contributing sub-cultures ethnic communities and performance groups of Sri Lanka through their residual, modified and stereotypical cultural performances including the performances by Sinhala, Tamil and Indigenous communities representing Buddhist, Hindu, and other religious beliefs and ideologies.
In Vitro Rooting of Gyrinops walla in Activated Charcoal-Containing Semi-Solid Culture and Filter Paper-Bridged Liquid Culture Systems
Authors: Selvaskanthan S. , Eeswara J. P.
Published: October 2024

Plant tissue culture is the best option in producing planting material for cultivation programmes of Gyrinops walla. Perfection of in vitro rooting protocol for this species is the most decisive step in micropropagation. In the present study the effect of physical state of substrate, different concentrations of sucrose, IBA and NAA in media containing activated charcoal on in vitro rooting was investigated. In experiment-1, 0.2% (w/v) activated charcoal was added in to the ½ MS medium fortified with 30 or 40 g/L sucrose and varying concentrations of IBA or NAA (0, 0.1, 0.5, 1.0 and 2.0 mg/L). In experiment-2, filter paper-bridged liquid medium was used with 40 g/L sugar and varying concentrations of IBA or NAA (0, 0.1, 0.5, 1.0 and 2.0 mg/L). The treatments were arranged in completely randomized design with three replicates. Percentage of rooted microshoots and number of roots per shoot were recorded. The ½ MS semi-solid medium with 0.2% activated charcoal, 40 g/L sucrose and 0.1 mg/L NAA resulted in the significantly highest rooting percentage (50%)while the significantly highest number of roots (6.0) were noted in ½ MS charcoal added (0.2%) basal medium with 40 g/L sucrose and 0.5 mg/L NAA. Shoots supported with filter paper bridge on ½ MS liquid medium, supplemented with 0.5 mg/L IBA, had the highest rooting percentage (66.7%) and the highest mean number of roots per shoot (3.0) (P<0.05). Results confirmed that in vitro rooting of G. walla could be perfected by optimizing the culture medium and its constituents.

Published: October 2024

This study investigated spatial patterns of chronic kidney disease of unknown aetiology (CKDu) patients in Badulupura village. The analysis utilized published locational data for all households, including households affected by CKDu, and all wells used by CKDu-affected patients (CPA wells). The study employed Average Nearest Neighbour (ANN) and Hot Spot Analysis (Getis-Ord Gi*) tools to assess the spatial clustering of CKDu households and CPA wells. The study also explored the impact of topographical factors such as elevation, slope, and distance to watershed boundaries on the spatial distribution of CKDu patients. The ANN analysis revealed a dispersed pattern for all wells, and a random distribution for all households. However, both CKDu households and CPI wells exhibited a clustered pattern, suggesting a location-specific cause for the spatial distribution of the disease. Additionally, overlaying CKDu-affected households on the digital elevation model revealed a concentration of CKDu hot spots in high-elevation areas, while cold spots were observed in low-elevation regions. Furthermore, the t-test was employed to investigate the significance of elevation, slope, and distance to the watershed boundaries in relation to CKDu distribution. The results indicated a significant (p<0.05) prevalence of CKDu in high-elevation areas, while no significant association was found with slope or distance to watershed boundaries. The study revealed the presence of localized CKDu hot spots and cold spots within a small geographical area, highlighting the importance of considering topographical factors and conducting comprehensive hydrogeological and geological studies to gain valuable insights into the spatial distribution of CKDu.
Effect of Coating Chemically Derived Chitosan from Shrimp Shell Wastes on Physical, Microbiological and Sensory Characteristics of Chicken Sausages
Authors: Mithushan P. , Pagthinathan M. , Ravikumar S. , Vahaful Nisath M. F.
Published: October 2024

Sausages have high moisture and protein content, making them extremely vulnerable to microbial deterioration. The antimicrobial qualities of chitosan coating prolong the shelf-life of sausages. The aim of this present study was to evaluate the effect of 0, 0.25, 0.5 and 1% (w/v) of chitosan coatings on microbiological, physical and sensory attributes of chicken sausages in cold storage (-10 °C). Chitosan was extracted from shrimp shell and dissolved in acetic acid to prepare 0.25, 0.5 and 1% of edible chitosan solution and control (0%). Sausages were coated by dipping in chitosan solutions. To find the best percentage of chitosan coating, physical, microbiological and sensory attributes were examined during the storage period. A number of TAB colonies was shown to have increased during the storage; nevertheless, the values were within the acceptable level (5.00 Log (CFU/g) in 0.25, 0.5 and 1% chitosan treated samples in two weeks of storage. The number of TAB colonies was not significantly (P>0.05) reduced between the samples treated with 0.25, 0.5 and 1% of chitosan. Further, hardness values were increased with the chitosan coating, while 1% chitosan-coated sausages had the highest value for hardness (27.93 N). Similarly, the WHC also increased with the chitosan coating. There was no significant difference observed (P>0.05) among 0.25, 0.5, and 1.0% of chitosan coating in WHC. pH values improved with the chitosan coating. Moisture and colour were not significantly (p>0.05) affected by chitosan coating. During storage, deteriorative changes occurred slowly in coated sausages. 1% chitosan coated sausages had the highest overall acceptability and maximum scores for odour, colour, taste, appearance and texture on the day 1 and 4th week of storage. Chitosan coating can be utilized as an edible coating material for the preservation of meat products.
Management Strategies for Older Patients with Diabetes Mellitus
Authors: Kim Won Jun
Published: October 2024

More than 30% of the Korean population aged ≥ 65 years has diabetes. Elderly patients with diabetes mellitus are more likely to have comorbidities and often suffer co-morbid cognitive and physical disabilities, depression, and polypharmacy. Older patients with diabetes and good health status can be treated in the same way as younger patients with diabetes. Treatment should be individualized and simplified as much as possible for patients with reduced functionality and comorbidity. The goal of glycemic control in elderly diabetic patients is to control symptoms of hyperglycemia, prevent hypoglycemic events, delay the occurrence of complications, and help patients maintain healthy lives.
Diabetes and Dietary Proteins-Protein Supplement Intake
Authors: Kim Dasom
Published: October 2024

Diabetes is a growing global health issue, with diet playing a crucial role in prevention and management. Protein, an essential nutrient for growth, repair, and metabolism, can significantly influence diabetes risk and control. High-protein diets, especially those rich in animal proteins, have been linked to increased risk of type 2 diabetes, while plant-based proteins may offer protective benefits. Studies suggest that excessive animal protein intake, particularly from red and processed meats, can increase diabetes risk due to higher saturated fat content. Conversely, plant-based proteins, such as soy, tofu, and nuts, are associated with improved insulin sensitivity and reduced inflammation. Protein supplements—especially whey and soy proteins—are known to help maintain muscle mass and improve metabolic indicators. However, the evidence supporting these benefits remains limited, and excessive protein intake may increase risks of other negative effects, such as impaired kidney function. Therefore, caution is advised when using these supplements. A balanced approach that emphasizes plant-based proteins while moderating animal protein intake is recommended for diabetes prevention and management. Future research should focus on personalized dietary strategies for optimal health outcomes.
Jammed joints and constricted heart: The science of tribology and missing lubricin. A case report on camptodactyly-arthropathy-coxa vara-pericarditis syndrome
Authors: Subramaniam Krishnan Ganapathy , Mohanty Satish , Sharma Dhruva , Tamildasan Komal , Reddy Narahari Srinath
Published: October 2024

An autosomal recessively inherited noninflammatory arthropathy known as camptodactyly, arthropathy, coxa vara, and pericarditis (CACP) syndrome was discovered in 1999. It is distinguished by synoviocyte hyperplasia and subcapsular fibrosis of the synovial capsule, which results in a shortage of lubricin production. The resulting lack of joint lubrication induces increased mechanical stress, causing progressive deformities that become evident with weight-bearing and heightened joint activity. Animal models with a lubricin gene knock-out display similar traits, underscoring the impact of mechanical stress on disrupting type II collagen on the articular surface. The gradual development of pericarditis and constriction often results in misdiagnosis as juvenile rheumatoid arthritis with cardiac involvement, but the defining feature remains the noninflammatory nature of the disease. Early recognition is pivotal, as interventions such as pericardiectomy and recombinant human lubricin hold promise for altering the disease’s natural course. In our familial case of CACP, two siblings exhibited distinct phenotypic variations – one with fibrosis-dominant features and pericardial constriction and the other displaying synovial hyperplasia without pericardial involvement.
Percutaneous closure of aortopulmonary window in a preterm infant
Authors: Gurav Aishwarya Prakash , Kumar Shine , Kumar Raman Krishna
Published: October 2024

Aorto-pulmonary window (APW) is a rare congenital heart disease. The non-restrictive types of APWs present at an early age and require early surgical correction. The transcatheter device closure in young infants pose significant challenges that include hemodynamic instability during arteriovenous loop formation and due to potential encroachment of the occlusive device on vital adjacent structures, and sizing of introducer sheaths and delivery systems. We report a successful transcatheter closure of an AP window in a 1.35 Kg preterm infant with heart failure requiring mechanical ventilation. To the best of our knowledge this is the smallest and youngest baby , wherein transcatheter device closure has been attempted for a non-restrictive aorto-pulmonary window. The procedure was done through a 4 French right femoral venous access, thus avoiding an arterial access. A 0.025 Terumo wire was maneuvered through the pulmonary artery across the APW without formation of an arteriovenous loop. The APW was successfully occluded with a Konar multi-functional device delivered via a 4-French delivery system. The baby could be successfully weaned off the ventilator and could be discharge. On 1 month follow up, baby was in good health and gaining adequate weight. Thus we conclude that careful selection of patients allows successful closure of APW, even in the smallest baby.
Heart failure following cavopulmonary shunt – An unusual story of desmin cardiomyopathy
Authors: Kadiyani Lamk , Ramakrishnan Sivasubramanian , Arava Sudheer Kumar , Seth Sandeep
Published: October 2024

Partial cavopulmonary shunt is an established procedure for patients with abnormal right ventricular (RV) physiology. Late failure of the Glenn shunt is usually due to further progression of the primary disease process. However, there may be surprises, as in our patient. We report an 8-year-old child who was diagnosed with tricuspid valve (TV) dysplasia with borderline RV hypoplasia. He underwent TV repair with a right cavopulmonary shunt. He presented with features of heart failure after 6 years of the surgery. An echocardiographic evaluation suggested a restrictive filling pattern of the RV with preserved size and function. Computed tomography and cardiac magnetic resonance imaging revealed a normal pericardial thickness with no evidence of myocardial involvement. Despite the contradicting clinical and imaging features, endomyocardial biopsy confirmed a diagnosis of desmin cardiomyopathy. Restrictive cardiomyopathy may remain an elusive diagnosis despite extensive imaging. In our case, the altered loading conditions due to a cavopulmonary shunt further masked pathophysiological hemodynamic changes.
Interventional management of an unusual cause of cyanosis in repaired tetralogy of Fallot
Authors: Kadiyani Lamk , Gupta Saurabh Kumar , Ramakrishnan Sivasubramaniam
Published: October 2024

Arterial desaturation following surgical repair of tetralogy of Fallot (TOF) is rare. In most instances, it results from residual right ventricular outflow tract obstruction, causing right-to-left shunt across residual interatrial or interventricular communication. In this report, we present an unusual scenario of arterial desaturation due to a recanalized left cardinal vein in a child with repaired TOF. We also discuss stepwise evaluation that led to successful identification and occlusion of the abnormal venous channel by percutaneous device closure.

Authors: Yumkham Ratna , Nagarathna C , Shakuntala B. S. , Sarada Rajkumari , Yumnam Gargi , Waikhom Bandana
Published: October 2024

ABSTRACT

Background:

The use of SHED might bring advantages for tissue engineering over the use of stem cells from adult human teeth as SHEDs were reported to have higher proliferation rate and increase cell population doublings as compared with stem cells from permanent teeth.

Objective:

The study’s objective was to assess the growth kinetics and tri-lineage differentiation capacity of stem cells derived from human exfoliated deciduous teeth.

Material and Method:

After being propagated through multiple sequential subcultures, adherent fibroblastic cells in the pulp tissue culture from human exfoliation teeth were evaluated to assess their tripotent differentiation potential into bone, cartilage, and adipose cell lineages.

Result:

The stem cells derived from dental pulp had a comparatively high ability for proliferation and successfully differentiated into chondrocytes and osteocytes while less significant for adipocytes.

Conclusion:

Stem cells from Human Exfoliated Deciduous teeth are mesenchymal stem cells which are multipotent and can serve as a promising incentive for therapeutic and future research purposes.

Trigeminal neuralgia (TN) is a debilitating condition characterized by excruciating facial pain resulting from dysfunction in the trigeminal nerve. Treatment options are limited. Noninvasive pulsed radiofrequency (PRF) therapy is an emerging promising approach to managing TN. This therapy provides pain control without tissue damage or unpleasant side effects compared to invasive procedures. Here, we present five cases of trigeminal neuralgia successfully managed with noninvasive PRF therapy. Our case series contributes to the existing literature and supports the potential efficacy of noninvasive PRF therapy for TN.

Objectives:

The current study aimed to evaluate the effectiveness of using a vibration device to ease pain during upper extremity injections. Specifically, the study aims to compare the pain levels of patients who receive the injection with and without the use of vibration therapy. The results of this study may have implications for improving patient outcomes and satisfaction during routine injection procedures.

Material and Methods:

This randomized controlled trial included patients aged 18 years or older who were scheduled to receive an injection in the upper extremity. A total of 60 patients were enrolled and randomized to either the intervention group or the control group using a computer-generated randomization sequence. The level of satisfaction and pain levels were assessed using a visual analog scale. The study was conducted in accordance with the Declaration of Helsinki and approved by the institutional review board.

Results:

The mean pain score immediately after the injection was 4.03 ± 2.11 out of 10 in the vibration group (n = 30), compared to 7.4 ± 1.37 out of 10 in the control group (n = 30) (P < 0.001). Patients in the vibration group also reported higher levels of satisfaction and comfort during the injection (P < 0.001). No adverse events were reported in either group.

Conclusion:

Our study proves that using a vibration device during upper extremity injections can effectively reduce postinjection pain and improve patient satisfaction. Further research is needed to explore this intervention’s long-term effects and feasibility in different clinical settings.
Iatrogenic tracheobronchial rupture in a fragile patient: A case report
Authors: Gonçalves Beatriz , Abreu João , Rodrigues Ricardo , Luís Mariana
Published: October 2024

An acute injury of the tracheobronchial system is a rare but potentially life-threatening condition that can be caused by medical procedures. Diagnosis requires a thorough evaluation of the patient’s medical history, physical examination, and imaging tests. Identification of a tracheal rupture in patients under sedation or general anesthesia may be difficult, and a strong clinical suspicion is essential. Treatment can be conservative or surgical, depending on the severity of the injury and the patients’ clinical status. The key prognostic determinant is a prompt identification and appropriate management.
Efficacy of dexmedetomidine as an adjuvant in transverse abdominal plane blocks for cesarean section pain management: A systematic review and meta-analysis
Authors: Alsultan Dalal
Published: October 2024

Postoperative pain management is a key component of care for women undergoing cesarean section. Although the use of dexmedetomidine (DMD) as an adjuvant to local anesthetics in transverse abdominal plane (TAP) blocks has been investigated, its conclusive evidence on its efficacy and safety remains unclear. A standardized data extraction form, under the guidance of the PRISMA protocol, was devised for selecting relevant studies across eight databases, without restrictions on the publication period. In most of the eight studies reviewed, the group receiving DMD demonstrated a significant extension of the duration of analgesia compared to the control group [mean difference (MD) = -3.37 hours, 95% confidence interval (CI) = -6.10 to -0.65 hours, Z = 2.43, P = 0.02]. The DMD group also showed a significant decrease in Visual Analogue Scale pain scores (MD = -1.38, 95% CI = -2.52 to -0.24, Z = 2.37, P = 0.02) in comparison to the control group. Nevertheless, significant heterogeneity was observed across the studies, potentially due to differences in study design, patient demographics, and dosing protocols, among other factors. The results of this meta-analysis indicate that DMD could be an effective adjuvant to local anesthetics in TAP blocks, potentially improving postoperative pain management and decreasing the need for additional analgesia. Nevertheless, the considerable heterogeneity among the studies warrants cautious interpretation of these results.
Comparison of effects of dexmedetomidine with ketofol and ketofol alone on quality of sedation in pediatric patients undergoing magnetic resonance imaging: A prospective randomized controlled double-blind trial

Published: October 2024

Background and Aim:

Patient movement during magnetic resonance imaging (MRI) is the most frequent cause of artifacts and poor scan quality. Children cannot lie still. Thus, anesthesia is required to keep the child calm and immobile. This randomized double-blinded clinical trial compares the clinical effects of the addition of dexmedetomidine as premedication with ketofol on the quality of sedation. We hypothesized that the addition of dexmedetomidine would improve the quality of sedation.

Methods:

A total of 132 children aged 6 months to 10 years were randomized into groups DK (dexmedetomidine–ketofol) and K (ketofol). DK received an intravenous bolus of dexmedetomidine (0.5 mcg/kg) as premedication 10 minutes prior. Both the groups were induced with ketofol (0.5 mg/kg), and sedation was maintained with propfol infusion (100 mcg/kg/min). The primary objective was the quality of sedation as assessed by the University of Michigan Sedation Scale. Image quality, requirement of rescue propofol dose, recovery, and adverse events were also studied. Data are given as median [interquartile range (IQR)] or frequency.

Results:

All 132 children completed MRI scans. The DK group showed significantly better quality of sedation, 71% versus 47% of children, a median difference of 1 (-0.569 to -0.0969), P < .005, a better quality of scan, a reduced number of additional doses of propofol, and a decreased total dose of propofol. Hemodynamic parameters and recovery times for the two groups were similar. There were no significant side effects in both groups.

Conclusion:

The quality of sedation and the quality of the MRI scan are greatly improved by administering dexmedetomidine (0.5 mcg/kg) 10 minutes before to induction. Additionally, this technique decreases the need of propofol and gives better hemodynamic stability without delaying the recovery time.
Efficacy of epidural anesthesia in minimally invasive cardiac surgery
Authors: Shimizu Chiho , Wakimoto Mayuko , Kita Takashi
Published: October 2024

Introduction:

The most commonly performed minimally invasive cardiac surgery (MICS) is lateral minithoracotomy, which requires one of the most painful incisions. Adequate postoperative pain management is essential for cardiac surgery to prevent perioperative complications. Thoracic epidural analgesia (TEA) is the gold standard for thoracotomy; however, it is still controversial because of the risk of epidural hematoma following systematic heparinization. The objective of our study was to investigate the safety and efficacy of TEA following MICS.

Methods:

The clinical data of patients aged over 18 years who underwent elective MICS and received epidural analgesia along with general anesthesia between January 2014 and March 2019 were reviewed. Data were collected, including patient demographics, operative data, postoperative pain, postoperative course, and complications. Chronic pain was evaluated 6 months after discharge, and we defined it as a NRS score ≧3. Postoperative complications included epidural-related complications.

Results:

Seventy patients were included in the analysis. The mean NRS score was below 2. We collected chronic pain data from 52 patients and found that 11 patients had chronic pain. TEA-related complications were not observed.

Conclusion:

The current observational study revealed that TEA following lateral thoracotomy was effective for acute pain as well as chronic pain without causing any severe epidural-related complications. Protocols to prevent potential devastating complications, including epidural hematoma, should follow the American Society of Regional Anesthesia and Pain Medicine recommendation. If the rules are strictly followed, TEA can be a safe and effective pain management method for patients who undergo MICS.

Data aggregation and sensors data fusion would be very helpful in a number of developing fields, including deep learning, driverless cars, smart cities, and the Internet of Things (IoT). An advanced smart home application will test the upgraded Constrained Application Protocol (CoAP) using Contiki Cooja. Smart home can enhance people’s comfort. Secure authentication between the transmitter and recipient nodes is essential for providing IoT services. In many IoT applications, device data are critical. Current encryption techniques use complicated arithmetic for security. However, these arithmetic techniques waste power. Hash algorithms can authenticate these IoT applications. Mobile protection issues must be treated seriously, because smart systems are automatically regulated. CoAP lets sensors send and receive server data with an energy-efficient hash function to increase security and speed. SHA224, SHA-1, and SHA256 were tested by the CoAP protocol. Proposed model showed that SHA 224 starts secure sessions faster than SHA-256 and SHA-1. The ChaCha ci. This study proposed enhanced ChaCha, a stream cipher for low-duty-cycle IoT devices. For wireless connections between the IoT gateway and sensors with a maximum throughput of 1.5 Mbps, the proposed model employs a wireless error rate (WER) of 0.05; the throughput rises with an increase in the transmission data rate.
Shifted Yangians and Polynomial $R$-Matrices
Authors: Hernandez David , Zhang Huafeng
Published: October 2024

We study the category

\mathcal{O}^{\mathrm{sh}}

of representations over a shifted Yangian. This category has a tensor product structure and contains distinguished modules, the positive prefundamental modules and the negative prefundamental modules. Motivated by the representation theory of the Borel subalgebra of a quantum affine algebra and by the relevance of quantum integrable systems in this context, we prove that tensor products of prefundamental modules with irreducible modules are either cyclic or cocyclic. This implies the existence and uniqueness of morphisms, the

R

-matrices, for such tensor products. We prove the

R

-matrices are polynomial in the spectral parameter, and we establish functional relations for the

R

-matrices. As applications, we prove the Jordan–Hölder property in the category

\mathcal{O}^{\mathrm{sh}}

. We also obtain a proof, uniform for any finite type, that any irreducible module factorizes through a truncated shifted Yangian.
On a Degenerating Limit Theorem of DeMarco–Faber
Authors: Okuyama Yûsuke
Published: October 2024

One of our aims is to complement the proof of DeMarco–Faber’s degenerating limit theorem for the family of the unique maximal entropy measures parametrized by a punctured open disk associated to a meromorphic family of rational functions on the complex projective line, degenerating at the puncture. This complementation is done by our main result, which rectifies a key computation in their argument. We also establish and use a direct and explicit translation from degenerating complex dynamics into quantized Berkovich dynamics, instead of using DeMarco–Faber’s more conceptual transfer principle between those dynamics.
