Authors: Quimuanga Zeca Catuco André , Bunga Vieira dos Santos 
Published: September 2024

Esta pesquisa teve o objetivo de indicar algumas contribuições da metodologia de ensino da Matemática por meio de exploração e resolução de problemas aliados a situações sociais, com o recorte na aplicação de sistemas de equações lineares na análise de malhas viárias com ruas de sentido único. Optou-se por esta abordagem de ensino porque ela possibilitou despertar o interesse e gosto dos alunos pela Matemática e, desta forma estreitar as relações dos alunos com a Matemática, quebrar a prática habitual de transmitir fórmulas, teoremas, axiomas e exercícios, mostrando alguma utilidade dos sistemas de equações lineares em cruzamentos de ruas, para determinar o número de veículos que deve entrar e sair no mesmo cruzamento para que o trânsito seja regularizado. Caraterizada como uma pesquisa pedagógica de abordagem qualitativa, de natureza aplicada, foi desenvolvida com 60 alunos da 12ª Classe da Escola do Magistério CDTE Pedro Benga Lima “Foguetão” do Uíge (Angola) por meio da resolução de duas situações-problemáticas dentro da sala de aula, dividindo os alunos em grupos e uma atividade de campo na quadra nº 6 da Centralidade do Kilomosso, Cidade do Uíge em Angola. Pela satisfação e envolvimento ativos dos alunos durante a realização, os resultados obtidos apontam que a metodologia de ensino da Matemática por meio de exploração e resolução de problemas aliados a situações sociais utilizada, permitiu demonstrar a aplicação de sistemas lineares na análise malhas viárias, comprovando assim que a Matemática está ligada à realidade de todos. Diante disso, espera-se que a metodologia apresentada neste artigo sirva de um indicador e guia para reduzir o insucesso dos alunos na aprendizagem da Matemática.

Los accidentes cerebrovasculares son la tercera causa de muerte en todo el mundo, y la Organización Mundial de la Salud (OMS) predice un aumento del 27% en estas enfermedades para 2025. La hemorragia intraparenquimatosa es una enfermedad cuya incidencia aumenta con la edad. Este aumento se atribuye, entre otros factores, a estilos de vida poco saludables, el alcoholismo y el tabaquismo, así como al envejecimiento de la población, factores que predisponen al aumento de los niveles de presión arterial, que a su vez se considera uno de los principales factores de riesgo para la enfermedad. El propósito de esta investigación es conocer cómo mejorar la prevención, la atención clínica y la investigación de las hemorragias intracerebrales. Estudio en el que se aplica la investigación cualitativa descriptiva. Con un enfoque descriptivo, para brindar un panorama detallado y rico de las experiencias y percepciones de otros investigadores que han realizado trabajos relacionados con el tema de la hemorragia intracerebral traumática, se utilizó el análisis documental: en el que se registraron las publicaciones a partir de diferentes bases de datos, como Pubmed, Scopus, Google Scholar y Scielo, realizando una cuidadosa revisión de estos documentos para asegurar la validez y confiabilidad de los resultados.
On the Origin of a Broad Quasiperiodic Fast-propagating Wave Train: Unwinding Jet as the Driver

Published: October 2024

Abstract
Large-scale extreme-ultraviolet waves commonly exhibit as single wave front and are believed to be caused by coronal mass ejections. Utilizing high spatiotemporal resolution imaging observations from the Solar Dynamics Observatory, we present two sequentially generated wave trains originating from the same active region: a narrow quasiperiodic fast-propagating (QFP) wave train that propagates along the coronal loop system above the jet and a broad QFP wave train that travels along the solar surface beneath the jet. The measurements indicate that the narrow QFP wave train and the accompanying flare’s quasiperiodic pulsations (QPPs) have nearly identical onsets and periods. This result suggests that the accompanying flare process excites the observed narrow QFP wave train. However, the broad QFP wave train starts approximately 2 minutes before the QPPs of the flare, but it is consistent with the interaction between the unwinding jet and the solar surface. Moreover, we find that the period of the broad QFP wave train, approximately 130 s, closely matches that of the unwinding jet. This period is significantly longer than the 30 s period of the accompanying flare’s QPPs. Based on these findings, we propose that the intermittent energy release of the accompanying flare excited the narrow QFP wave train confined propagating in the coronal loop system. The unwinding jet, rather than the intermittent energy release in the accompanying flare, triggered the broad QFP wave train propagating along the solar surface.
Massive Star Formation Starts in Subvirial Dense Clumps Unless Resisted by Strong Magnetic Fields

Published: October 2024

Abstract
Knowledge of the initial conditions of high-mass star formation is critical for theoretical models, but are not well observed. Built on our previous characterization of a Galaxy-wide sample of 463 candidate high-mass starless clumps (HMSCs), here we investigate the dynamical state of a representative subsample of 44 HMSCs (radii 0.13–1.12 pc) using Green Bank Telescope NH3 (1,1) and (2,2) data from the Radio Ammonia Mid-Plane Survey pilot data release. By fitting the two NH3 lines simultaneously, we obtain velocity dispersion, gas kinetic temperature, NH3 column density and abundance, Mach number, and virial parameter. Thermodynamic analysis reveals that most HMSCs have Mach number <5, inconsistent with what have been considered in theoretical models. All but one (43 out of 44) of the HMSCs are gravitationally bound with virial parameter α
vir < 2. Either these massive clumps are collapsing or magnetic field strengths of 0.10–2.65 mG (average 0.51 mG) would be needed to prevent them from collapsing. The estimated B-field strength correlates tightly with density,

, with a similar power-law index as found in observations but a factor of 4.6 higher in strength. For the first time, the initial dynamical state of high-mass formation regions has been statistically constrained to be subvirial, in contradiction to theoretical models in virial equilibrium and in agreement with the lack of observed massive starless cores. The findings urge future observations to quantify the magnetic field support in the prestellar stage of massive clumps, which has rarely been explored so far, toward a full understanding of the physical conditions that initiate massive star formation.
The Formation Rate and Luminosity Function of Fast Radio Bursts
Authors: Chen J. H. , Jia X. D. , Dong X. F. , Wang F. Y. 
Published: September 2024

Abstract
Fast radio bursts (FRBs) are millisecond-duration flashes with unknown origins. Their formation rate is crucial for unveiling physical origins. However, the luminosity and formation rate are degenerate when directly fitting the redshift distribution of FRBs. In contrast to previous forward-fitting methods, we use Lynden-Bell’s c
− method to derive the luminosity function and formation rate of FRBs without any assumptions. Using the nonrepeating FRBs from the first Canadian Hydrogen Intensity Mapping Experiment FRB catalog, we find a relatively strong luminosity evolution, and luminosity function can be fitted by a broken power-law model with a break at 1.33 × 1041 erg s−1. The formation rate declines rapidly as (1 + z)−4.9±0.3 with a local rate of 1.13 × 104 Gpc−3 yr−1. This monotonic decrease is similar to the rate of short gamma-ray bursts. After comparing this function with the star formation rate and stellar mass density, we conclude that the old populations, including neutron stars and black holes, are closely related to the origins of FRBs.
A novel mutation in a case of XY DSD with progressive virilization at puberty
Authors: Wadhwa Jyoti , Namburi Divyasri , Kunnuru Sumana , Kauloorkar Bhoomika , Anne Beatrice 
Published: September 2024

ABSTRACT
We present a case of ambiguous genitalia, not being evaluated at birth and presenting with progressive virilization at puberty. The usual set of differential diagnoses in a patient with the presence of bilateral gonads and progressive virilization includes five alpha-reductase deficiency, 17 beta-hydroxysteroid dehydrogenase 3 deficiency, partial androgen insensitivity syndrome, and partial gonadal dysgenesis. Human chorionic gonadotropin (HCG) stimulation test performed on our patient suggested the presence of five alpha-reductase deficiency with a testosterone/dihydrotestosterone (T/DHT) ratio of 32; however, the genetic analysis revealed the presence of autosomal dominant, heterozygous pathogenic mutation in NR5A1 gene Exon 5 with autosomal dominant heterozygous mutation in DHX37 gene Exon 18. While NR5A1 mutation is a known cause of testicular dysgenesis; DHX37 is a novel gene associated with ambiguous genitalia and there are only a few case reports presenting with a combined mutation. The patient exhibited a high T/DHT ratio on HCG stimulation and also exhibited poor virilization despite being on testosterone therapy for 2 years. Whether these mutations affect five alpha-reductase enzymes inhibiting testosterone to dihydrotestosterone conversion is unknown.
Understanding sexual differentiation: A case series on persistent Mullerian duct syndrome
Authors: Stephen Samuel Frank 
Published: September 2024

ABSTRACT

Introduction:
Persistent Mullerian duct syndrome (PMDS) is a rare form of sexual differentiation, where the failure to produce functional anti-Mullerian hormone (AMH) or a defective type II AMH receptor (AMHRII) leads to the persistence of Mullerian ducts in otherwise normal males.

Materials and Methods:
Cytogenetic testing was done on lymphocyte cultures from samples of peripheral blood. G-banding was done, and cultures were analyzed using the Ikaros software to visualize metaphase chromosomes and reported as per the International System for Human Cytogenetic Nomenclature.

Results:
A series of eight patients with PMDS with 46 XY on karyotyping were identified between 2001 and 2016 from 22 days to 24 years of age. PMDS was diagnosed incidentally through clinical pointers such as inguinal hernia (n = 5, 62.5%) and undescended testes (n = 5, 62.5%). Male type II (n = 4, 50%) was the most common morphological type. Two of the older patients aged 4 and 24 years had intra-tubular germ cell neoplasia and mixed germ cell tumor, respectively.

Conclusion:
Knowledge of the presenting features, morphology, and histopathology of PMDS enables a better understanding of the intricacies of normal and abnormal sexual differentiation.

Published: September 2024

ABSTRACT
Chronic calcific pancreatitis in children is rare, and type 3c diabetes (T3cD) with extensive pancreatic calcification in the first decade of life is even rarer. We describe a case of T3cD in an 11-year-old boy who presented with hyperglycemic osmotic symptoms. Initial pancreatic autoantibody testing was positive for high titer, creating a diagnostic dilemma. This article examines the role of autoimmunity in the pathogenesis of post-pancreatitis diabetes and emphasizes the importance of performing pancreatic imaging before, or in addition to, carrying out pancreatic autoantibody tests, even in pediatric diabetes cases. This unique case also highlights the shortcomings in the current diagnostic criteria for T3cD.

Published: September 2024

Abstract

Background and Aims:
Caudal block is a commonly used regional anesthesia technique providing perioperative analgesia for young children with the disadvantage of a short duration of action after a single shot. Dexamethasone and magnesium as adjuvants could offer significant analgesic benefits. We compared the analgesic effects of dexamethasone or magnesium added to caudal ropivacaine in pediatric patients undergoing infraumbilical surgery.

Methods:
A total of 75 children (aged 6 months–9 years) were randomly assigned to three groups in a double-blinded manner. Group DR received ropivacaine 0.2% 1.5 mL/kg combined with dexamethasone 0.1 mg/kg in 0.9% normal saline, Group MR received magnesium 50 mg in 0.9% normal saline with 0.2% ropivacaine 1.5 mL/kg, and Group R received 1.5 mL/kg of 0.2% ropivacaine. The primary objective was the duration of analgesia. The secondary objectives were the duration of motor blockade, hemodynamic changes such as heart rate, mean arterial pressure, and adverse effects. One-way analysis of variance, Kruskal–Wallis, and Chi-square tests were applied for statistical analysis.

Results:
The groups were comparable with respect to age, sex, and duration of surgery. The hemodynamic parameters were comparable among all groups intraoperatively and postoperatively. The mean duration of analgesia in Group DR was 1216.6 ± 153.5 min, Group MR was 542.3 ± 111.7 min, and Group R was 325.8 ± 37.1 min (P < 0.001). The duration of motor block and adverse effects was comparable among all groups.

Conclusion:
The addition of dexamethasone to caudal ropivacaine significantly prolonged the duration of postoperative analgesia compared to magnesium as an adjuvant.
Low-temperature Radiofrequency Lesioning for Glossopharyngeal Neuralgia
Authors: Chakravarty Ashish 
Published: September 2024

Abstract
Glossopharyngeal neuralgia (GPN) is a rare craniofacial disorder of the ninth cranial nerve characterized by severe neuralgic pain occurring along the distribution of the glossopharyngeal nerve. Antiepileptics such as carbamazepine and oxcarbazepine form the frontline treatment for the condition. Percutaneous radiofrequency thermoablation (PRT) is a minimally invasive neuroablative procedure which has shown good results in medically refractory cases. Currently, for the management of GPN pulsed radiofrequency treatment is preferred over PRT as it offers neuromodulatory rather than neurodestructive effects. Low-temperature PRT has shown to preserve the neuronal architecture and maintain the potential for nerve repair. This modality can be a useful alternative for the management of GPN.
Efficacy and Tolerability of Rizatriptan and Sumatriptan in Acute Migraine in Indian Patients: A Comparison between Two Frontiers
Authors: Kushwah Anjali , Shinde Meghna 
Published: September 2024

Abstract

Introduction:
Migraine is a debilitating, neurological disorder, characterized by episodes of ipsilateral headache, often associated with symptoms such as nausea, vomiting, vertigo, and other sensory symptoms. The role of commonly used triptans (5 HT1B/1D agonists) – rizatriptan and sumatriptan – is very scarcely explored in Indian population with migraine. Thus, this study was done to assess the efficacy and tolerability of 10 mg oral rizatriptan versus 50 mg oral sumatriptan for the treatment of acute moderate-to-severe migraine.

Materials and Methods:
A total of 113 migraine patients attending the neurology outpatient department were enrolled in our study. The efficacy parameters included in our study were pain relief, pain free at 2 h, and sustained pain-free response in both the groups. Adverse drug reactions, if any, were recorded as a measure of tolerability.

Results:
Overall rizatriptan showed superior efficacy in terms of pain relief at 2 h (71.92% vs. 60.71%) with a statistically significant difference at 1.5 h (P = 0.0084) and 2 h (P = 0.0099) and complete abolition of headache (pain free) at all the four time points spaced 30 min apart (43.85% vs. 26.78%). Twenty-four hours sustained pain-free response was also more in the rizatriptan group (63.42% vs. 47.06%) as compared to that in the sumatriptan group. The frequency of adverse effects was seen more in the sumatriptan group (83.89%) than those receiving rizatriptan (49.68%).

Conclusions:
Rizatriptan 10 mg was found to be more efficacious and tolerable as compared to sumatriptan 50 mg.
Occupational Exposure to Artificial Ultraviolet Radiation from Welding in Australia
Authors: Fritschi Lin , Driscoll Tim , Nguyen Ha , Carey Renee N. 
Published: September 2024

Abstract

Background:
Artificial ultraviolet radiation (UVR) is produced during welding and can cause damage to both the eyes (ocular) and the skin (dermal). We aimed to investigate the protection used by welders to reduce their exposure to ocular and dermal UVR.

Methods:
We conducted a cross-sectional online survey in Australia that asked welders about their welding tasks and the control measures they used to protect against UVR exposure.

Results:
There were 634 respondents, of whom 411 undertook welding themselves, 36 supervised other welders, and 130 both supervised and welded. Dermal UVR exposure occurred in 7.8% of welders and 14.4% of supervisors, whereas ocular UVR exposure occurred in 16.8% of welders and 33.1% of supervisors. The use of personal control measures was much lower among supervisors than welders; however, the presence of warning signs or barriers was reported more often by supervisors.

Conclusions:
Despite the well-known acute and chronic effects of exposure to UVR from welding, there are still many welders and supervisors who do not use adequate protection.

Therefore the present study was conducted to investigate the effect of teaching assistants (TA) on the degree of satisfaction of undergraduate students of Anesthesia with training in the internship unit.

MATERIALS AND METHODS:
This descriptive-cross-sectional study was conducted in 2023. The sample of the research was the Anesthesia undergraduate students who were included by census method. First, a questionnaire was designed and psychometric to check the level of satisfaction (ICC = 0.992). then it was given to students who had completed at least 1 unit of internship with TAs. The results were analyzed with SPSS software Version 22 and one-way-ANOVA and independent t-statistical tests (P Value <0.05).

RESULTS:
A total of 60 questionnaires were completed and analyzed. Among them, 39 were female students and 21 were male students who were studying in the 4th, 6th, and 8th semesters. the level of satisfaction of Anesthesia students with training by teaching assistants is at a favorable level with an average of 61.06. There was no statistically significant difference between the variables of gender and academic semester with the degree of satisfaction. 6th-semester students had the highest level of satisfaction with an average satisfaction of 61.63.

CONCLUSION:
According to the results, Anesthesia undergraduate students are satisfied with the clinical training by TAs, at a favorable and high level. Therefore it is recommended that teaching assistants in education be used to improve students’ satisfaction and learning levels.
