Rosette Nebula Outburst Gaia 24djk from the Young Stellar Object V557 Mon
Authors: Carvalho Adolfo S. , Hillenbrand Lynne A. 
Published: February 2025

Abstract
A previously faint young stellar object (YSO), V557 Mon, rapidly brightened in late 2024 and is currently at least ΔG = 3.3 mag brighter than its typical pre-outburst brightness. The ongoing outburst is identified in the Gaia Alerts system as Gaia24djk. We obtained a 1–2.5 μm spectrum of the object and find the spectrum is dominated by line emission and continuum excess consistent with rapid YSO accretion, similar to the star EX Lup during its outburst state. We speculate that the burst, which has not yet reached its peak brightness, may become an FU Ori outburst, which would be evidenced by the emission spectrum turning into an absorption spectrum.
Determination of the Abundance of Mercury from the Hg ii Line at 5677.10 Å in Late B-type Stars. XV. HD 79158 (36 Lyncis)
Authors: Monier Richard 
Published: February 2025

Abstract
The weak line of Hg ii located at 5677.10 Å is not detected in high signal-to-noise ratio NARVAL I profiles of the Helium-weak star HD 79158. This is probably due to the large projected equatorial velocity, the moderate excess of mercury in this star and a lower signal-to-noise ratio of the NARVAL I profile at this wavelength. The synthesis of various spectral intervals also yields new measurements of the abundances of helium, magnesium, aluminium, silicon, titanium, chromium, manganese, iron, yttrium and mercury. The abundance of mercury is estimated from the commonly used Hg ii line at 3983.94 Å which is broadened by rotation and blended with the neighbouring line Y ii at 3982.59 Å. Most of these new measurements agree roughly with previous measurements.

Published: February 2025

Background: Diabetic ketoacidosis (DKA) is a common hyperglycaemic emergency in persons living with diabetes (PLWD), and outcomes of treatment depend on the precipitating factor.Methods: A cross-sectional prospective study of patients admitted in the adult high care unit of Nelson Mandela Central Hospital was carried out from 19 February 2022 to 19 January 2023. Patients were assessed for demographic, clinical profiles and outcomes concerning precipitating factors. The outcomes were duration of admission and discharge from the hospital as alive or dead.Results: There were 55 PLWD, all black African, predominantly females, known with diabetes with a mean age of 38 ± 15.8 years. The main precipitants for DKA in descending order were infections (47%), treatment omission (30%) and a new diagnosis of diabetes (19%). The mean duration of admission for all patients was 8.2 ± 5.3 days. The length of hospital stay was 9.5 ± 5.2 days, 5.6 ± 2.2 days, and 8.6 ± 7.6 days, respectively (p = 0.118). The mortality in all patients was 9 (16.4%), and all but one death was associated with sepsis. There were no significant differences in the HbA1c among patients with infection (13.9 ± 3.8), those who omitted treatment (12.6 ± 4.7) and those newly diagnosed (12.2 ± 2.2) (p = 0.620).Conclusion: The high mortality rates in our DKA patients were mainly related to infections. The high HbA1c indicates poor glycaemic control preceding DKA. Improving glycaemic control, preventing infections, and early treatment of infections can reduce DKA-related mortality among patients.Contribution: This study provides a comprehensive analysis of DKA in resource-limited settings, focusing on its precipitating factors, clinical profiles, and outcomes among adults in the Eastern Cape, South Africa. Infections were identified as the leading precipitant, with poor glycaemic control prevalent across all cases and a mortality rate of 16.4%, primarily due to sepsis. The findings highlight the urgent need for strategies to improve glycaemic control, prevent infections, and ensure timely interventions to reduce DKA-related mortality. This research aligns with the Journal of the Colleges of Medicine of South Africa’s mission to advance clinical practice by addressing critical healthcare challenges in underserved communities, offering insights applicable across the region.
Seasonal trends in methylphenidate use: A mirror of misuse or compliance?
Authors: Schoeman Renata , Benjamin Stefan J. 
Published: February 2025

Background: A steady growth in the use of medication for the treatment of attention-deficit hyperactivity disorder (ADHD) has been evident over the past few decades. While growth attests to increased awareness of ADHD and improved access to diagnosis and treatment, concerns have been raised about poor adherence to treatment and diversion of medication.Aim: This current study explored the seasonal and/or temporal use of methylphenidate (MPH) in South Africa.Setting: The study was conducted in South Africa.Methods: A retrospective database analysis was conducted to examine unit sales of MPH over a 9-year period. The unit sales of MPH were compared to those of atomoxetine for the same period.Results: Unit sales for MPH peaked in May and October, which coincided with the academic high-pressure periods for school learners and university students. This was most evident for MPH immediate release 10 mg. There was a noticeable decrease in unit sales for MPH during December. Atomoxetine demonstrated much less seasonal variation.Conclusion: The seasonal and/or temporal use of MPH fluctuates following the academic calendar. These changes are driven by both temporary interruptions of treatment, such as ‘drug holidays’, and the misuse and diversion of MPH for non-medical use. This holds significant implications for interventions to improve ADHD outcomes. It is crucial to balance accessibility to treatment with the prevention of misuse of MPH.Contribution: Our findings highlight the need to reconsider current policies and regulations regarding the appropriate diagnosis and management of ADHD and the scripting, dispensing and monitoring of MPH.
Salivary interleukin-10 and interleukin-17 – Potential biomarkers for assessing oral cancer and oral potentially malignant disorders – A comparative study
Authors: Jayachandran S , Preethi Manoharan , Nagarajan Nivethitha 
Published: February 2025

Abstract

Background:
Staging of oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMDs) is considered as the most important prognostic indicator, but salivary proteins such as interleukins (ILs) can serve as potential biomarkers. The aim of this study was to assess the presence of salivary IL-10 and IL-17 in OSCC and OPMD (oral submucous fibrosis and oral leukoplakia).

Materials and Methods:
This was a hospital-based, in vivo, cross-sectional, comparative study. A total of 90 patients (N = 90) were included in the study. Whole unstimulated saliva was collected and subjected to enzyme-linked immunosorbent assay (ELISA): 30 from histopathologically confirmed OSCC (Group 1, n = 30), 15 from clinically diagnosed OSMF (Group 2, n = 15), 15 from clinically diagnosed OL (Group 3, n = 15), 15 from patients who had tobacco habits but no clinical lesions of OSCC/OL/OSMF (Group 4, n = 15), and 15 from healthy controls (Group 5, n = 15).

Results:
Statistical analysis was performed by SPSS®25.0 (analysis of variance [ANOVA], Tukey’s post hoc test, and Mann–Whitney U test). Both IL-10 and IL-17 were found in saliva. One-way ANOVA between groups showed IL-10 did not vary significantly within groups (P = 0.853), but IL-17 varied significantly between groups (P = 0.000). Mann–Whitney U test used to compare IL-10 and IL-17 between stage III and IV of OSCC showed that they did not vary significantly.

Conclusion:
IL-17 can indicate the presence of ongoing inflammation toward developing OPMD/OSCC, proving it as a potent diagnostic biomarker. An increase in IL-17 with successive stages of OSCC proves it as a prognostic biomarker for OSCC.

Authors: Karthik Haritha , Nair Tanvi V. , Muthalib Shezla , Devi B. Vaishnavi , Sathish S. , Natanasabapathy Velmurugan , Suresh Nandini 
Published: February 2025

Abstract

Background:
Calcium hydroxide is the most used intracanal medicament, but the presence of its remnants within the root canal before obturation has been found to negatively impact the treatment outcome. Hence, its complete removal is essential for the success of the treatment. Different chelators along with dynamic activation systems for calcium hydroxide retrieval have been reported in the literature.

Aim:
The aim of this study was to assess the efficiency of different calcium chelators acting as an adjunct to dynamic irrigation in calcium hydroxide retrieval and if 1% phytic acid has a role in the retrieval of calcium hydroxide.

Materials and Methods:
This in vitro study included 180 single-rooted mandibular premolars. Access opening followed by working length determination and biomechanical preparation was done. Canals were filled with Metapex. The sample teeth were categorized into 1% phytic acid, maleic acid, and saline groups. The groups were subcategorized based on the use of irrigant agitation techniques such as passive ultrasonic irrigation (PUI), Endovac, combination of Endovac and PUI, and conventional needle agitation. Pre- and postoperative cone-beam computed tomography volumetric percentage difference was measured by manual segmentation using HOROS software. Statistical analysis was performed using analysis of variance with post hoc Tukey’s test with P < 0.05.

Results:
One percent phytic acid showed the maximum calcium hydroxide removal ranging between 97% and 99%, but there was no statistical difference between different chelator groups used along with the different agitation techniques. However, the use of dynamic agitation techniques has shown better calcium hydroxide removal when compared to conventional needle irrigation.

Conclusion:
Calcium chelators showed increased efficiency in calcium hydroxide retrieval compared to saline irrigation when used along with dynamic agitation techniques. There is no difference between the chelator groups when used along with the different agitation techniques.
Impact of Bruxism in Alzheimer’s Disease
Authors: Suganya S. , Balasubramanian K. , Kesavamoorthy Yugesh 
Published: February 2025

Abstract
Bruxism is a clinical condition where a person grinds, clenches, or gnashes their teeth often involuntarily. It can take place during awakefulness or during sleep. The condition is furthermore common in sleep. It affects around 22% of the population globally. It is caused by various factors such as stress, psychological, or temporomandibular disease. This condition was commonly encountered in Alzheimer’s disease (AD). Persistent clenching or grinding causes tooth loss and infections. Due to continuous mastication, cytokines such as interleukin (IL) 6, IL 8, and tumor necrosis factor were produced which might promote Aβ formation causing neuronal death. In this context, we would like to express the role of proinflammatory cytokines in association with AD and to ensure preventive measures toward bruxism.
p-adic Simpson correspondences for principal bundles in abelian settings
Authors: Heuer Ben , Werner Annette , Zhang Mingjia 
Published: February 2025

Abstract
We explore generalizations of the p-adic Simpson correspondence on smooth proper rigid spaces to principal bundles under rigid group varieties G. For commutative G, we prove that such a correspondence exists if and only if the Lie group logarithm is surjective. Second, we treat the case of general G on ordinary abelian varieties, in which case we prove a generalization of Faltings’ “small” correspondence to general rigid groups. On abeloid varieties, we also prove an analog of the classical Corlette–Simpson correspondence for principal bundles under linear algebraic groups.
Становление первых храмов Кронштадта в XVIII — первой половине XIX вв.
Authors: Галимова Е.Ю. 
Published: February 2025

Кронштадт в XVIII в. активно развивался, превращаясь в мощнейшую военную крепость на северо-западе России. В городе базировался Балтийский флот, поэтому проживало много моряков. Для удовлетворения религиозных потребностей военнослужащих по распоряжению Петра I в Кронштадте появились первые храмы. Однако при их строительстве часто возникали различные финансовые и административные трудности. Автор исследует процесс возведения и развития храмов, их роль в объединении прихожан и морально-нравственном воспитании. Анализ исторического опыта по становлению храмов для военнослужащих является особо актуальным в наши дни, когда государство предпринимает определенные шаги в направлении поддержки реализации прав военнослужащих на вероисповедание.
Kronstadt actively developed in the 18th century, turning into the most powerful military fortress in the north-west of Russia. The Baltic fleet was based in the city, so many sailors lived. To meet the religious needs of the military, by order of Peter I, the first churches appeared in Kronstadt. However, during their construction, various financial and administrative difficulties often arose. The author explores the process of construction and development of temples, their role in the unification of parishioners and moral education. An analysis of the historical experience in the formation of temples for military personnel is especially relevant today, when the state is taking certain steps towards supporting the realization of the rights of military personnel to worship.

Objective: To investigate the association between the sociodemographic status and patient satisfaction level with reference to thalassemia management involving tertiary public sectors of Pakistan.
Methodology: This cross-sectional study was conducted from July-Sept 2020, at Bolan Medical Hospital (BMCH) & Sandeman Provincial Hospital (SPH) Quetta. Systematic-random sampling was done to gather data through preformed structured questionnaire. Ethical consideration was acquired before the research. Participants who don’t have hearing or talking issues, without mental confusion or any systemic illness, were part of this research. The satisfaction scale was a 5-item Likert-type. A higher score indicates a higher degree of satisfaction from the respondent.
Results: A total of 100 participants were included in this study. Regarding earning family members, 81% of the respondents have only 1 earning member. More than half (58%) of the fathers of the children were laborers by occupation. Chi square test revealed statistical insignificant relationship of occupation of earning members of family, area of living with level of satisfaction among participants, where p-values were 0.133 and 0.456 respectively. Chi square test showed statistically significant relationship between quality of life and level of satisfaction among participants, where p-value was 0.028.
Conclusion: The present study concluded low satisfaction level among the Pakistani population with reference to the management of the thalassemic major patients in the public sector because of their declined socioeconomic status. Their monthly income could have played a major role in availing the facilities from the public sector that deals with the mass population.

Afro-Latinx, Hispanic, and Latinx Identity: Understanding the Americas
Authors: García Eric Bayruns 
Published: February 2025

Abstract
This article argues that (C) the term “Afro-Latinx” is more apt than “Hispanic” or “Latinx” in a significant number of cases. Three premises support this conclusion. The first premise (P1) is that use of “Afro-Latinx” provides subjects with understanding of how certain events depend on anti-Black racism, US society’s racially unjust structure, and US colonial policy. The second premise (P2) is that neither the term “Hispanic” nor the term “Latinx” provides subjects with this understanding of how certain events depend on anti-Black racism, US society’s racially unjust structure, and US colonial policy. The third premise (P3) is that the term “Afro-Latinx” provides subjects with more understanding of these events than the terms “Hispanic” and “Latinx.” To motivate the argument, the article presents the case of Jose “Kiko” García’s murder by the New York City police and the uprising that ensued.
Black Nausea: Existential Awareness of Antiblack Racism and a Phenomenology of Caution
Authors: Reed Corey 
Published: February 2025

Abstract
When Black agents engage spaces and phenomena that suggest a racialized, potential danger, Black agents shift in their existential understanding of themselves and their phenomenological engagement with the world. This article describes that existential and phenomenological change, and examines the issue of hypothetical anti-Black racism. Utilizing Sartrean and Fanonian conceptions of existential phenomenology, this article explicates three terms: Black nausea, Black vertigo, and a phenomenology of caution. These terms are used to describe the tension that Black agents experience when they are confronted with phenomena related to the history of anti-Black racism, and that confrontation brings their Blackness to the surface of their consciousness. This article argues that “Black paranoia” is an inappropriate label for a justified phenomenology of caution, and that Black freedom includes addressing these nauseating phenomena.
Reparative Racial Justice from Wariness in the Rawlsian Original Position
Authors: Beaudette Spencer William 
Published: February 2025

Abstract
Charles Mills has argued that Rawlsian justice cannot recognize racial injustice, cannot apply to a society so nonideal as the United States, and provides harmful support for “color-blind” approaches to racial justice. This article derives duties of backward-looking reparative justice from a Rawlsian Original Position (OP) by arguing that representatives in the OP know that social groups may exist and that bias tracking those groups may become encoded in social institutions over time, even in ideal circumstances. Representatives will have cause to design historically backward-looking institutions that can investigate claims of institutional bias and make recommendations for repair. This approach improves upon other responses to Mills because it does not make a “lexical error” by relying on a principle of fair equality of opportunity. Finally, this article shows how Rawlsian ideal theory, when applied to a state like the United States, naturally gives way to a nonideal theory like Mills’s own.
