The desulfurization process of high-sulfur coal from Jambi Province, Indonesia was investigated using peroxyacetic acid (PAA) as mild oxidising agent by ultrasonic wave. This study reports the utilization of a mixture of acetic acid and 6% hydrogen peroxide (CH3COOH: H2COOH) under sonication to extract organic sulfur from coal. The ultrasonic shockwave separates sulfur from the coal's macromolecular structure by breaking the chemical connections that hold sulfur to coal. The optimum concentration, temperature, and processing time for the coal desulfurization process were determined using the Central Composite Design-Response Surface Methodology (CCD-RSM) to overcome the traditional methods that make finding the optimal standard difficult and time-consuming. Sonicating coal at 30 ˚C for 30 minutes with 70:30 (CH3COOH: H2COOH) was found to be the ideal parameter. Results shows that all inorganic and some of the organic sulfur could be removed from the coal using mild conditions without severely affecting the coal microstructure as observed in the FESEM-EDX. Through the FTIR analysis, the organic sulfur structural parameters show the relative abundance of aliphatic sulfur (thiol, thiophene and sulfone) and organic matters in these coals decreased after the coal treated by PAA.To clarify its chemical effect, the production regularities of hydroxyl radical under ultrasonic field was determined using the iodine release method. Experimental results also showed that the production rule of hydroxyl radical was consistent with the desulfurization degree. These findings confirmed that the synergistic action of physical and chemical effects of the ultrasonic played an important role in this desulfurization process, which could serve as a reference for further optimizing the coal desulfurization process.

Published: July 2024

Poiseuille flows are crucial in various fields, including engineering and the chemical industry, explaining phenomena such as increased blood pressure in narrowed capillaries and aiding in the design of fluid management systems. Traditionally, studies on Poiseuille flows have focused on Newtonian fluids in non-moving pipes, limiting advancements in the field. This research addresses the gap by exploring the Poiseuille flow of a viscoelastic non-Newtonian second-grade nanofluid. These second-grade fluids, applicable in polymer processing and cosmetics manufacturing, exhibit both shear-thinning and shear-thickening properties under certain conditions. The study analytically solves the flow characteristics of blood nanofluids, reducing the governing equations to ordinary differential equations using standard Poiseuille flow assumptions. The simulation results reveal that among the three nanofluids tested, graphene-blood nanofluid achieves the highest velocity, while copper-blood nanofluid exhibits the lowest. Additionally, the velocity of graphene-blood nanofluid decreases with an increase in volume percentage. This work not only advances the understanding of non-Newtonian fluid dynamics but also provides insights into optimizing fluid management systems in biomedical and industrial applications.

Authors: Yankyera Patrick , Kusi Gabriel , Obeng-Denteh William
Published: July 2024

This paper presents a comprehensive exploration of the morpho-syntactic analysis and the implications of Matthew 8:1-4 within the context of Pentecostal and Charismatic churches in Ghana. The methodology employed involved a meticulous examination of the linguistic structure of the passage, followed by a qualitative investigation of its impact on present-day Christian ministry. The primary objective was to bridge the gap between linguistic analysis and practical application, shedding light on the spiritual and cultural relevance of this biblical text. The findings of this study revealed a twofold significance. First, this study provides a deeper understanding of its original language and structure. Pastors and ministers can leverage this knowledge to enhance the accuracy and impact of their sermons. Second, the spiritual significance of the passage underscores themes of healing, faith, compassion, and inclusion. These findings inspire faith and devotion among church members, emphasizing God’s compassionate nature and encouraging believers to seek divine intervention in their lives. In the realm of testimony-giving practices, this study recommended that Ghanaian Pentecostal and Charismatic churches incorporate the themes of Matthew 8:1-4 into their testimonial narratives. Encouraging congregants to share testimonies aligned with these themes can foster a stronger faith community and a deeper connection between the biblical message and the lives of believers. Ultimately, this study contributes to the body of knowledge by bridging the gap between linguistic analysis and practical ministry application.

Understanding the Variability of Helium Abundance in the Solar Corona Using Three-fluid Modeling and Ultraviolet Observations
Authors: Ofman Leon , Yogesh  , Giordano Silvio
Published: July 2024

The variability of helium abundance in the solar corona and the solar wind is an important signature of solar activity, solar cycle, and solar wind sources, as well as coronal heating processes. Motivated by recently reported remote-sensing UV imaging observations by Helium Resonance Scattering in the Corona and Heliosphere payload sounding rocket of helium abundance in the inner corona on 2009 September 14 near solar minimum, we present the results of the first three-dimensional three-fluid (electrons, protons, and alpha particles) model of tilted coronal streamer belt and slow solar wind that illustrates the various processes leading to helium abundance differentiation and variability. We find good qualitative agreement between the three-fluid model and the coronal helium abundance variability deduced from UV observations of streamers, providing insight on the effects of the physical processes, such as heating, gravitational settling, and interspecies Coulomb friction in the outflowing solar wind that produce the observed features. The study impacts our understanding of the origins of the slow solar wind.
Predictions for Sparse Photometry of Jupiter-family Comet Nuclei in the LSST Era
Authors: Donaldson A. , Snodgrass C. , Kokotanekova R. , Rożek A.
Published: July 2024

The Legacy Survey of Space and Time (LSST) at Vera C. Rubin Observatory will deliver high-quality, temporally sparse observations of millions of solar system objects on an unprecedented scale. Such data sets will likely enable the precise estimation of small-body properties on a population-wide basis. In this work, we consider the possible applications of photometric data points from LSST to the characterization of Jupiter-family comet (JFC) nuclei. We simulate sparse-in-time lightcurve points with an LSST-like cadence for the orbit of a JFC between 2024 and 2033. Convex lightcurve inversion is used to assess whether the simulation input parameters can be accurately reproduced for a sample of nucleus rotation periods, pole orientations, activity onsets, shapes, and sizes. We find that the rotation period and pole direction can be reliably constrained across all nucleus variants tested, and that the convex shape models, while limited in their ability to describe complex or bilobed nuclei, are effective for correcting sparse photometry for rotational modulation to improve estimates of nucleus phase functions. Based on this analysis, we anticipate that LSST photometry will significantly enhance our present understanding of the spin state and phase function distributions of JFC nuclei.
Direct fire-induced reptile mortality in the Sierra Morelos natural protected area (Mexico)
Authors: González-Fernández Andrea , Couturier Stephane , Dotor-Diego Rodrigo , Martínez-Díaz-González Ricardo , Sunny Armando
Published: July 2024

Little is known about fire as an agent of direct animal mortality, and specifically, there is controversy regarding the effects of fire on reptiles. In the Sierra Morelos natural protected area in Mexico, both unplanned (e.g., man-made illegal and accidental burns) and prescribed burns occur during the dry season. In this study, we assessed direct fire-induced reptile mortality in the Sierra Morelos natural protected area by comparing live and dead individuals. Of the 14 reptile species reported in the area, seven were found dead due to fire. One-third of the individuals found in 2021 (34% of 169 ind.) and 2022 (33% of 33 ind.) were killed by fire. The mean density of detected dead individuals was 1.60 ± 2.99 individuals/ha in 2021 and 0.31 ± 0.27 individuals/ha in 2022. Mortality densities were similar in areas subjected to prescribed burns and in areas affected by unplanned burns (W= 37.5, p = 0.4383). Since our survey likely underestimated the actual mortality caused by fire, our findings show the important direct impact of fire on the reptile community of the Sierra Morelos natural protected area and support the notion that anthropogenic fire can represent a serious risk for reptiles in fragile ecosystems.
A new species of Neotropiconyttus Kirkaldy (Hemiptera, Reduviidae) in a cacao plantation from the Colombian Napo Province, including a key to species, and taxonomic notes of the genus

Published: July 2024

A new species of the genus Neotropiconyttus Kirkaldy, 1909 (Hemiptera: Heteroptera: Reduviidae: Harpactorinae: Harpactorini) is described and illustrated. Neotropiconyttus armandoi Gamboa & Gil-Santana, sp. nov. represents the first record of the genus for the Province of Napo in Colombia, and the first description of a male individual in the genus. The male specimen representing the new species was collected on a leaf of cacao (Theobroma cacao L.-Malvaceae). Its remarkable similarity in external coloration and structure with that of the true bug Monalonion dissimulatum Distant, 1883 (Hemiptera: Miridae) inhabiting cacao agroforestry systems suggests that the new species could be part of a mimetic complex that incorporates phytophagous and predator bugs. Comments and figures of type specimens of Neotropiconyttus alboannulatus (Stål, 1855) and Neotropiconyttus dama (Burmeister, 1838), and a key to the species of the genus are also provided.
Un éléphant dans la pièce ? La liberté de l’enseignement comme régime d’accommodement de la religion
Authors: Hennette-Vauchez Stéphanie
Published: July 2024

La présente contribution analyse le régime juridique de l’enseignement privé, fondé sur le principe constitutionnel de la liberté de l’enseignement. Elle propose de lire ce régime comme fondé sur une logique d’accommodement de la religion, c’est-à-dire comme un régime qui, simultanément, reconnaît la légitimité de l’affirmation, par les établissements d’enseignement privé, d’un caractère propre, y compris confessionnel, et aménage, en son nom, l’application des règles communes. Ce faisant, l’article affirme l’intérêt qui s’attache à étudier de près le régime juridique de l’enseignement privé, non seulement au regard de l’importance de la loi Debré de 1959 pour la compréhension du régime français de laïcité mais encore, du fait de la relativisation à laquelle il invite de la présentation commune de la tradition juridique et politique française comme précisément opposée à toute notion d’accommodement – notamment vis-à-vis de la religion.
L’enseignement libre
Authors: Larzul Tanneguy
Published: July 2024

La notion d’enseignement libre recouvre dans notre droit deux réalités distinctes mais complémentaires. Elle renvoie d’abord à la liberté de l’enseignement qui, pour assurer le droit à l’instruction, offre le choix de recourir à tel ou tel mode de scolarisation, dans l’enseignement public, dans l’enseignement privé, sous contrat avec l’État ou hors contrat. Fruit de notre histoire, cette liberté première est désormais établie comme principe fondamental reconnu par les lois de la République de la liberté. C’est une liberté protégée. Dans une perspective plus pédagogique qu’institutionnelle, l’enseignement libre c’est aussi la liberté d’enseigner, c’est-à-dire pour les maîtres la libre détermination des savoirs que l’on transmet et des méthodes pour y parvenir. La liberté de l’enseignement n’implique pas la liberté d’enseigner et cette dernière n’a jamais bénéficié du même statut que la première. C’est une liberté encadrée.
La laïcité et l’enseignement
Authors: Philip-Gay Mathilde
Published: July 2024

Même si elle a ses propres fondements législatifs et constitutionnels, la laïcité de l’enseignement est au cœur du principe fondamental de la laïcité de la République. C’est la volonté d’adoucir les passions qu’elle suscite qui explique tant les particularités des règles s’appliquant aux usagers des écoles publiques, que la spécificité de certains principes encadrant les activités en lien avec l’enseignement dans les établissements publics ou privés, et à l’université.
Les fascistes de la République sociale italienne condamnées à mort
Authors: Nubola Cecilia
Published: July 2024

Dans l’Italie en guerre des années 1943-1945, les femmes trouvent de nouveaux espaces d’action au service de la République sociale italienne de Mussolini. Elles sont employées dans le Service auxiliaire féminin, dans les groupes paramilitaires des Brigades noires, dans les bureaux de police, comme espionnes professionnelles et multiplient les actes de délinquance. Après la guerre, accusées de « collaborationnisme » avec l’envahisseur allemand, elles sont jugées par des tribunaux spéciaux (cours d’assises extraordinaires) et, parmi elles, une dizaine sont condamnées à mort. Aucune condamnation à mort n’est exécutée, la quasi-totalité des femmes retrouvant la liberté après quelques années à la suite de procès en révision ou d’amnisties. L’article retrace à la fois leurs histoires, leurs actions criminelles, leurs motivations et leurs justifications des choix effectués, mais aussi les décisions de justice qui ont conduit aux condamnations, ainsi que la présence de stéréotypes de genre dans le discours juridique et la défense des accusées.
Modeling mosquito-borne disease dynamics via stochastic differential equations and generalized tempered stable distribution
Authors: Sabbar Yassine , Raezah Aeshah A.
Published: July 2024

In this study, we introduce an enhanced stochastic model for mosquito-borne diseases that incorporates quarantine measures and employs Lévy jumps with the generalized tempered stable (GTS) distribution. Our proposed model lacks both endemic and disease-free states, rendering the conventional approach of assessing disease persistence or extinction based on asymptotic behavior inapplicable. Instead, we adopt a novel stochastic analysis approach to demonstrate the potential for disease eradication or continuation. Numerical examples validate the accuracy of our results and compare the outcomes of our model with the GTS distribution against the standard system using basic Lévy jumps. By accounting for the heavy-tailed nature of disease incidence or vector abundance, the GTS distribution enhances the precision of epidemiological models and predictions.

Proust entre le nihilisme schopenhauerien et le symbolisme schellingien : un paradoxe esthétique fondateur pour le XXe siècle ?
Authors: Marot Patrick
Published: July 2024

Que les révolutions opérées par Proust et Faulkner aient souvent
été lues soit sur le mode de la convergence, soit en miroirs inversés,
pose question. Plus spécifiquement centrée sur l’auteur de laRecherche, cette étude entend
interroger certains aspects des réactions, à la lecture de cette œuvre
unanimement mais très diversement érigée en référence, d’écrivains
contemporains ou de cadets comme Valéry, Beckett, Sartre ou Gracq,
dont les approches révèlent à la fois leur propre positionnement dans
le champ romanesque, et les enjeux d’une redéfinition de ce qui est
attendu de la littérature. Au-delà se dessinent peut-être,
explicitement ou non, les implications contradictoires d’un statut
métaphysique de la littérature moderne.
Giono à l’école de Proust
Authors: Morello André-Alain
Published: July 2024

Si l’influence de Faulkner sur Giono est désormais connue et
analysée par la critique, celle de Proust l’est nettement moins.
Pourtant, Giono a lu et relu Proust. Il l’évoque dans une lettre de
1926 à Lucien Jacques, et dans son Journal, il affirme l’avoir lu « au moins
dix fois soigneusement ». Certaines de ses œuvres portent la marque de
cette lecture. Dans Jean le
bleu, Giono semble bien suivre les chemins ouverts par Proust
dans « Combray » : la découverte de la sensualité est associée à celle
de la littérature, et le récit d’enfance est pleinement un
apprentissage de la création, ainsi qu’une exploration du monde
naturel. Si Noé, comme
Le Temps retrouvé, est le
roman du romancier, avec Mort
d’un personnage, Giono se souvient de la mort de la grand-mère
dans Le Côté de
Guermantes.
Les deux côtés de SiomRichard Millet, de Faulkner à Proust
Authors: Laurichesse Jean-Yves
Published: July 2024

L’une des originalités de l’œuvre de Richard Millet est d’entrer en
dialogue tout à la fois avec Faulkner et avec Proust. À partir de La Gloire des Pythre (1995),
l’écrivain construit autour de son village natal, rebaptisé Siom, un
territoire littéraire qu’il peuple de personnages et d’histoires entre
réalité et légende, à la manière du comté de Yoknapatawpha, et dans
une forme polyphonique qui doit aussi quelque chose à Faulkner. Mais
quand, avec Ma vie parmi les
ombres(2002), il entreprend, via un narrateur alter ego, de
partir à la recherche de son enfance et de son histoire familiale,
tout en racontant son cheminement vers l’écriture, c’est sous le signe
d’un rapport proustien à la mémoire, aux sensations, à la lecture.
L’article s’attache à identifier les échos des deux grands romanciers
dans ces deux romans majeurs de la littérature contemporaine.
« Ce petit groupement d’animaux et d’humains de la ferme » Jeanne Bemer-Sauvan, de l’expérience sensible de la campagne à la fusion mystique
Authors: Schoentjes Pierre
Published: July 2024

Mystique de la Ferme
et Mon âme en sabots,
deux livres publiés en 1933 par cette écrivaine aujourd’hui oubliée
sont analysés dans une perspective écopoétique. Une capacité
d’observation exceptionnelle, servie par une écriture au rythme très
maîtrisé, permet à cette écrivaine de ressusciter le monde des
campagnes d’avant 1914-18. L’analyse est l’occasion de montrer comment
dans l’entre-deux-guerres des écrivains ont pu s’inspirer du monde
rural sans tomber dans le régionalisme et en ne taisant pas les
réalités moins plaisantes des campagnes. L’originalité et l’intérêt de
Jeanne Bemer-Sauvan qui, enfant, a fait l’expérience émerveillée de la
nature, réside en ceci que son écriture des sens, éminemment attentive
aux réalités concrètes de la nature, sert de point d’appui à une
vision mystique du monde.

Cet article se focalise sur un groupe spécifique de zones frontalières qui ont été soumises à une exploitation conjointe par des communautés voisines. Une attention particulière est portée aux zones frontalières connues sous le nom de κοιναὶ χῶραι (« régions communes »), attestées quelques inscriptions conservant des détails sur leurs origines et leur statut. Le Péloponnèse hellénistique représente un domaine d’étude fort intéressant, car il fournit un ensemble de témoignages à la fois limité et diversifié.
Les confins au centre : étude de la vitalité de la recomposition identitaire dans La guerra mortal de los sentidos (2002) de Roberto Castillo
Authors: Boyer Émilie
Published: July 2024

La guerra mortal de los sentidos (2002) de Roberto Castillo, écrivain et philosophe hondurien, raconte l’enquête menée par El Buscador del Hablante Lenca pour trouver le dernier locuteur de la langue autochtone lenca. L’histoire se déroule dans la zone frontalière avec le Salvador, autour de la localité fictionnelle d’El Gual, présentée comme un « antiguo pueblo de indios » et se développe dans une accumulation de personnages et de situations qui transforme cet espace des confins en centre fondamental de la recomposition identitaire d’une société héritière des rapports de force coloniaux. Non seulement la narration transforme la zone en centre d’intérêt international – le Buscador est un linguiste espagnol et les habitants reçoivent la visite d’un ambassadeur états-unien – mais elle se peuple aussi d’« indios » habituellement marginalisés dans l’Histoire de la région. Dans une narration fragmentée et foisonnante, Castillo défie les échelles spatiales, les hiérarchies ethniques et les rapports de pouvoir locaux et mondiaux. La succession de portraits parfois contradictoires de l’insaisissable « Hablante Lenca » conteste par exemple le réalisme de la résurrection utopique d’une forme originelle de la langue lenca et la définition homogène d’une identité autochtone.
Ausências, objetos e sujeitos periféricos no documentário brasileiro contemporâneo
Authors: Velasco Leão Daniel
Published: July 2024

Historicamente, o documentário brasileiro se constitui como um discurso sobre o Outro. Em seus primórdios, aventureiros quase todos europeus percorriam o país registrando paisagens e famílias provincianas. Na modernidade, realizado por intelectuais de classe média, dedicou-se a buscar a identidade nacional (ou latino-americana), denunciar as mazelas sociais e “dar voz” aos camponeses e moradores de favelas, todos considerados periféricos. O documentário contemporâneo destaca-se daquelas manifestações por comportar relevantes relatos sobre a classe, o gênero e a raça da pessoa que o realiza. Isto decorre de um duplo movimento: antigos sujeitos passam a virar a câmera para si, enquanto outros sujeitos passam a realizar filmes. Atribui-se tal mudança a circunstâncias históricas que teriam contribuído para ambos movimentos, ademais mutuamente influenciados: o advento de novas tecnologias (permitindo uma democratização da produção e propiciando uma abordagem mais íntima, marca central do “Giro Subjetivo” constatado por Sarlo) e a deflação das narrativas realizadas a partir de rígidos paradigmas sociológicos, que perdem terreno após a queda do Muro de Berlim (e, no Brasil, do final de ditadura) para abordagens mais subjetivas que acentua o lugar de fala. Nessas produções, muitas vezes as “periferias” se tornam novos “centros”. Demonstraremos essa mudança no documentário contemporâneo, mencionando a incontornável produção de Eduardo Coutinho (em sua abertura ao imaginário e ao relato do Outro) e acentuando suas consequências na representação de pessoas indígenas (a partir do emblemático Vídeo nas Aldeias) e negras (especialmente em Sementes — mulheres pretas no poder (Éthel Oliveira e Julia Mariano, 2020)

Published: July 2024

The Sustainable Development Goals (SDGs) were approved by the global community in 2015as a collaborative plan to achieve a sustainable future. The achievement of sustainable development goals needs successful global linkages and partnerships (SGD-17) that can organize resources, share technologies, knowledge, and collaborate efforts between countries and organizations. However, global partnerships and linkages experience several barriers and challenges that hinder their effectiveness and impede advancement towards digitalization, green technologies, and regional diversification. This research intends to make up this gap by addressing aforementioned problems through examining role of global linkages to achieve sustainable development goals, identifying the main challenges and barriers in achieving these objectives, and to recommend polices and suggestions to strengthen these linkages and maximize their impact. To achieve the objectives of the study, a thorough review of academic literature, government reports, industry databases and policy documents, questionnaire survey and expert interviews were carried out to understand the present level of knowledge about global linkages and sustainable development goals. The data was obtained by using well-structured questionnaires through experienced professionals working as academic research, government official, NGOs and private sector professionals working in the construction industry. An online questionnaire was floated among different groups from which 128 returned and 32 were rejected, as the respondents have no understanding about sustainable development. Mean Item Score through SPSS was used to analyze the data.
Utilization of WEAP Software to Assess Current and Future Water Demand of Karachi City
Authors: Hanan Muhammad Abdul , Malik Muhammad Waqas
Published: July 2024

The availability of fresh water in the required quantity is the major challenge in Karachi city. There is a need to evaluate the potential of available water resources and devise a suitable distribution mechanism for the city. This study aims to determine the current water situation of Karachi City and it predicts the future water situation till 2040 considering 30 gallons per capita per day (GPCD) as an annual requirement per person. The study is conducted with the help of WEAP software. WEAP software uses different scenarios to estimate future water needs. In the software, water needs of Karachi from 2020 to 2040 were assessed and analysis of water demand, unmet demand, supply delivered, and demand site coverage was carried out. During modeling, a growth rate of 2.31% per year was used. The result indicates that the water demand will increase to 759.064 million gallons per day (MGD) in 2040, so an extra supply of 336.564 MGD will be required to meet water demands and urbanization of the city. To meet this unmet demand, it is suggested that water leakage be reduced as proposed by the Karachi Water & Sewerage Board (KWSB). Moreover, water conservation techniques and the use of treated wastewater along with the existing water are recommended to reduce the unmet demand.

Published: July 2024

Climate change as a result of global warming has become one of the worlds’ most pressing concerns. The release of greenhouse gases (GHG), primarily carbon dioxide (CO2) emissions into the atmosphere increases global warming. The concrete is the second most used material and cement is the key element in concrete. The cement production releases GHG in the atmosphere, which increases global warming and consequently results in climate change. This research utilizes, fly ash (FA) as 100% replacement of cement in concrete, which will reduce the reliance of construction industry on the cement production and will help to reduce the adverse impacts of climate changes. Moreover, recycled aggregates (RA) prepared from construction and demolition (C&D) wastes are used as varying percentage replacements of natural aggregates (NA) in cement-less recycled aggregate concrete (CRAC), which will help to reduce the depletion of natural resources. This research investigates the influences of varying percentage replacements of NA with RA (0%, 25%, 50%, 75% and 100%) and molarity of NaOH solution (12 M, 14 M and 16 M) on the compressive strength (CS) and flexural strength (FS) of CRAC mixes. A total of 15 CRAC mixes were prepared. Each mix comprised three 100 mm cube specimens and three prism specimens sized 75 mm x 75 mm x 300 mm. The research concluded that the CS and FS decreased with the increase in percentage replacements of NA with RA. Moreover, the CS and FS increased as the molarity of NaOH solution was increased from 12 M to 16 M. The CS and FS was reduced by 29.1% and 31.1% respectively at 100% replacement of NA with RA at 16 M compared to 12 M NaOH solution.

This umbrella review aimed to summarize and provide a general evaluation of the effectiveness of current treatments for male infertility and assess the quality of evidence and possible biases. An umbrella review of systematic reviews and meta-analyses available in PubMed, Web of Science, and Scopus, covering studies published up to October 2023, was conducted. Sperm concentration, morphology, and motility were used as endpoints to evaluate the effectiveness of the treatments. Of 2998 studies, 18 published meta-analyses were extracted, yielding 90 summary effects on sperm concentration (n = 36), sperm morphology (n = 26), and sperm motility (n = 28) on 28 interventions. None of the meta-analyses were classified as having low methodological quality, whereas 12 (66.7%) and 6 (33.3%) had high and moderate quality, respectively. Of the 90 summary effects, none were rated high-evidence quality, whereas 53.3% (n = 48), 25.6% (n = 23), and 21.1% (n = 19) were rated moderate, low, and very low, respectively. Significant improvements in sperm concentration, morphology, and motility were observed with pharmacological interventions (N-acetyl-cysteine, antioxidant therapy, aromatase inhibitors, selective estrogen receptor modulators, hormones, supplements, and alpha-lipoic acid) and nonpharmacological interventions (varicocele repair and redo varicocelectomy). In addition, vitamin supplementation had no significant positive effects on sperm concentration, motility, or morphology. Treatments for male infertility are increasingly diverse; however, the current evidence is poor because of the limited number of patients. Further well-designed studies on single treatment and high-quality meta-analysis of intertreatment comparisons are recommended.
Decannulation Dilemmas - Timing Tracheostomy Tube Removal in Children with Craniofacial Deformities - A Retrospective Study
Authors: Balaji S. M. , Balaji Preetha
Published: July 2024

Introduction:

Tracheostomy decannulation in children with craniofacial deformities poses challenges due to airway obstruction and the developing brain. This study aimed to compare decannulation outcomes based on age at tracheostomy and duration of cannulation so as to identify the best time for decannulation for children with long-term tracheostomy.

Methods:

This retrospective study included 12 children at a single centre who underwent decannulation after prolonged tracheostomy for craniofacial deformities. Data on demographics, clinical features, decannulation process and outcomes were collected. Children were divided into two groups: ≤6 years (n = 7) and >6 years (n = 5) at tracheostomy insertion.

Results:

All children underwent successful decannulation without immediate complications. One case of mild tracheomalacia and one of subglottic stenosis were treated pre-decannulation. Children ≤6 years demonstrated better post-operative adaptation in swallowing and speaking compared to the >6 years group. Notably, early and prolonged tracheostomy in the ≤6 years group was associated with easier adaptation post-decannulation. Social interaction was another challenge, particularly for the >6 years group.

Discussion:

The timing and duration of tracheostomy significantly impacts post-decannulation adaptation, likely due to factors such as neuroplasticity, muscle memory and psychological adjustment. This emphasises the need for comprehensive care, especially for older children. Early tracheostomy in children may allow them to adapt speech and swallowing skills, easing post-decannulation regain of skills. Conversely, older children with fully developed skills may struggle to relearn them after tracheostomy and decannulation. Age at tracheostomy and duration of cannulation influences decannulation outcomes in children with craniofacial deformities. Further research is crucial to develop targeted interventions for better post-operative care, particularly for older children.
The Progression and Prospects of the Gene Expression Profiling in Ovarian Epithelial Cancer

Published: July 2024

Ovarian cancer is one of the most common cancers with a high mortality rate among females worldwide. The understanding of the pathogenesis of the disease is highly important to provide personalized therapy to the patients. Ovarian cancer is as heterogeneous as colon and breast cancer which makes it difficult to treat. The development of gene signature is the only hope in providing targeted therapy to improve the survival of ovarian cancer patients. Malignant epithelial carcinomas are the most common cancers of the ovary with different histological and molecular subtypes and clinical behavior. The development of precursor lesions of ovarian carcinoma in the tubes and endometrium has provided a new dimension to the origin of ovarian cancers. The clinical utility of various gene signatures may not be logical unless validated. Validated gene signatures can aid the clinician in deciding the appropriate line of treatment.
Myomectomy: Choosing the Surgical Approach – A Systematic Review

Published: July 2024

Myomectomy has evolved from open laparotomy to laparoscopy, hysteroscopy, VNOTES and robotic myomectomy. The surgical approach in doing myomectomy depends on the type and location of the myoma and the surgeon’s expertise. Minimally invasive surgery has been the preferred approach due to the benefit of shorter hospital stay, lesser postoperative pain, earlier recovery, minimal blood loss and the cosmetic appearance of the scar. The success of this procedure depends on the incision technique, enucleation, and blood loss prevention by using hemostatic techniques and suturing techniques. Performing myomectomy for a large uterine myoma is a laparoscopic challenge; however, with the use of Lee-Huang point (midpoint between umbilicus and xiphoid) as the primary insertion and camera port, one can easily navigate thru the abdominal cavity in case the uterus is huge obscuring the umbilical port. Laparoscopic Myomectomy can be safely and efficiently performed by experienced laparoscopic surgeons regardless of myoma size, number and location. Removal of large myoma specimen from the abdominal cavity through the laparoscope became a challenge after the use of power morcellator was abandoned. To overcome this problem, the large myoma is placed inside an Endo bag and its edges brought extracorporeally through the port site. The myoma is incised in a C-manner using a scalpel to reduce the size. Myoma can also be removed using in-bag power morcellation. Fertility preservation is the long-term aim of doing myomectomy instead of hysterectomy in the management of leiomyoma aside from alleviating symptoms of abnormal uterine bleeding, urinary frequency and abdominal pain.

Strabismus surgery in a scleral buckle patient is a challenging task that requires precise planning and meticulous surgical skills to accomplish a successful outcome. We report a case of a 32-year-old male who presented with complaints of diminution of vision in the right eye (RE) for 23 years and outward deviation of RE for 5 years after blunt trauma with a ball. The patient was diagnosed with RE total retinal detachment (RD) with traumatic retinal dialysis. He underwent scleral buckling as RD surgery in 2004 followed by silicon oil removal 6 months later elsewhere. On ocular examination of the RE, the best corrected visual acuity was perception of light with accurate projection of rays in all four quadrants, there was grade III relative afferent pupillary defect with an exotropia of 20° on Hirschberg test. The prism bar reflex test revealed an exotropia of 50 prism diopters (PD) [Figure 1]. An anterior segment examination revealed posterior subcapsular and cortical cataracts. After taking a retina clinic opinion, the patient underwent uneventful RE cataract surgery with in-bag implantation of a foldable implant cataract surgery first, followed by strabismus surgery under a guarded visual prognosis. Clinically significant adhesion and the presence of the scleral buckle posed a magnificent challenge during the strabismus surgery. The plan was improvised to 8 mm lateral rectus recession with 4 mm hang loose recession irrespective of a large deviation under local anesthesia. To our surprise, a satisfactory primary position alignment within 10 PD (orthophoria) was achieved, which was maintained on subsequent follow-up visits. We report an interesting and challenging case of restrictive strabismus due to scleral buckle which emphasizes that surgical procedures and their outcomes may not always align with expectations. Therefore, it is necessary to adopt a flexible and customized approach to effectively manage such instances.

Background:

Community-acquired urinary tract infection (CA-UTI) is mostly treated empirically. There are limited studies on pediatric UTIs, their microbiological profile, and resistance patterns. Antimicrobial resistance and even multidrug resistance are on the rise among uropathogens in the pediatric population and may lead to complications in the long run. This study was done to know the microbiological profile and the resistance pattern of CA-UTI in the pediatric population of a tertiary care hospital in a tribal district of northern Odisha among children aged 5–14 years.

Methods:

A hospital-based cross-sectional study was done from January 2021 to June 2021. All cases aged between 5 and 14 years attending the pediatrics outpatient department suspected of UTI were included. Descriptive statistical analysis and regression analysis were done using the statistical software Stata SE 13.

Results:

Out of the total 311 cases, vomiting and pain in the abdomen were the most common clinical presentations. Significant bacterial growth was isolated in 74 samples. Escherichia coli (39.2%) was the predominant isolate. Resistance to cefotaxime (38.2%) and ciprofloxacin (36.4%) is highest and seen in both gram-positive and negative bacteria. Multidrug resistance was detected in 33.7% of the bacterial isolates.

Conclusion:

The present study highlights the problem of the rising resistance pattern of common bacterial pathogens causing CA-UTI in children. Further studies on genotypic resistance and appropriate measures are required to prevent the rapidly spreading resistance among these common uropathogens.
